All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

As described in the background art, the related art automobile has a problem that the space occupied by the waist support airbag adjusting valve and the side wing airbag adjusting valve is large, and the applicant has found that the problem arises because the waist support airbag of the seat is adjusted by the single waist support airbag adjusting valve and the side wing airbag is adjusted by the single side wing airbag adjusting valve, and the space occupied by the waist support airbag adjusting valve and the side wing airbag adjusting valve is large.

In view of the above technical problems, embodiments of the present application provide a seat adjusting valve and a vehicle, in which a plurality of control valves for controlling inflation or deflation of different air bags on a seat are integrated on one seat adjusting valve, so that the occupied space of the seat adjusting valve is reduced.

The principles and features of embodiments of the present application are described below with reference to the drawings, the examples are provided for the purpose of illustrating the embodiments of the present application and are not intended to limit the scope of the embodiments of the present application.

The present embodiments provide a vehicle, which may include a car, a bus, or a van, etc., primarily for carrying people and/or cargo. The vehicle includes automobile body, air pump, seat and seat governing valve, and air pump, seat and seat governing valve all set up in the automobile body, and the seat can include skeleton, cushion, back and a plurality of gasbag, and a plurality of gasbags can include waist and hold in the palm gasbag, flank gasbag and cushion gasbag etc. wherein, waist holds in the palm gasbag and flank gasbag all set up on the back, and the cushion gasbag sets up on the cushion.

Referring to fig. 1 to 5, the seat adjusting valve includes a valve body having an air inlet 110, a plurality of air outlet 120, and a plurality of air passage assemblies including an air inlet channel 130, an air outlet channel 140, and a delivery channel 150, the air inlet channel 130 and the air outlet channel 140 each communicating with the delivery channel 150, the plurality of air inlet channels 130 each communicating with the air inlet 110, the air inlet 110 communicating with an air pump, each air outlet channel 140 respectively communicating with a corresponding air outlet 120, each delivery channel 150 respectively communicating with a different air bag in the seat, inflating the air bag through the air inlet channel 130 and the delivery channel 150, and discharging the air in the air bag from the air outlet 120 through the delivery channel 150 and the air outlet channel 140.

The plurality of control components on the seat adjusting valve can comprise a waist support air bag control component, a side wing air bag control component and a cushion air bag control component, and a conveying channel 150 corresponding to the waist support air bag control component is communicated with the waist support air bag of the seat so as to inflate or deflate the waist support air bag of the seat; the corresponding conveying channels 150 of the flanking air bag control assembly are communicated with the flanking air bags of the seat so as to inflate or deflate the flanking air bags of the seat; the corresponding delivery channel 150 of the cushion airbag control assembly communicates with the cushion airbag of the seat to inflate or deflate the cushion airbag of the seat. The waist support air bags, the side wing air bags, the cushion air bags and the like of the seat are inflated or exhausted, so that a human body feels more comfortable after sitting on the seat.

Each control assembly includes an intake control valve and an exhaust control valve, each control assembly is disposed in a corresponding air passage assembly, and specifically, referring to fig. 4 and 5, the intake control valve is slidably disposed in the intake passage 130, so that the intake port 110 is connected to or disconnected from the delivery passage 150. The air pump provides air pressure and conveys air to the air inlet 110, and when the air inlet 110 is communicated with the conveying channel 150, the air is conveyed into the air bag through the air inlet 110, the air inlet channel 130 and the conveying channel 150 in sequence so as to inflate the air bag. When the gas inlet 110 is disconnected from the delivery channel 150 (see fig. 4), the gas from the gas pump will not be delivered to the delivery channel 150, and therefore, no gas is injected into the airbag.

Referring to fig. 4 and 5, an exhaust control valve is slidably provided in the exhaust passage 140 to connect or disconnect the exhaust port 120 with the delivery passage 150. When the exhaust port 120 communicates with the delivery passage 150, air in the airbag communicating with the delivery passage 150 flows from the delivery passage 150 to the exhaust passage 140 and is discharged from the exhaust port 120 to reduce the amount of air in the airbag.

When the exhaust port 120 is disconnected from the delivery passage 150 (refer to fig. 4), air in the airbag cannot flow to the exhaust passage 140, and thus cannot be exhausted from the exhaust port 120, so that the air in the airbag can be maintained.

According to the seat adjusting valve provided by the embodiment of the application, the plurality of control components for controlling inflation or deflation of different air bags on the seat are integrated on the valve body, so that the occupied space of the seat adjusting valve is reduced.

In some embodiments, the intake control valve may include an intake valve stem 210, referring to fig. 4, the intake valve stem 210 includes first and second seal segments 211 and 212 spaced apart in a direction parallel to an axis of the intake valve stem 210, and an intake rod body 213 connecting the first and second seal segments 211 and 212.

Referring to fig. 5, the air intake passage 130 may include a first fitting pipe section 131, an air intake chamber 132, and a second fitting pipe section 133 sequentially disposed in a direction parallel to an axis of the air intake valve stem 210, and referring to fig. 4 and 5, a first sealing section 211 is provided to pass through the first fitting pipe section 131, a second sealing section 212 is provided to pass through the second fitting pipe section 133, an air intake rod body 213 is provided to pass through the air intake chamber 132, and the air intake chamber 132 communicates with the conveying passage 150.

The air inlet valve rod 210 has a first position and a second position, when the air inlet valve rod 210 is in the first position (refer to fig. 4), the first sealing section 211 and the second sealing section 212 are in sealing engagement with the air inlet cavity 132, that is, the first fitting pipe section 131 and the second fitting pipe section 133 are not conductive to the air inlet cavity 132, and since the air inlet cavity 132 is not conductive to the first fitting pipe section 131, air of the air inlet 110 cannot flow from the first fitting pipe section 131 to the air inlet cavity 132, and therefore no air is replenished in the air inlet cavity 132. The second mating segment 133 is not in communication with the air intake chamber 132, and air within the air intake chamber 132 cannot flow out of the second mating segment 133, and therefore, air within the air intake chamber 132 cannot leak.

When the air inlet valve rod 210 moves to the second position along the direction from the second matching pipe section 133 to the first matching pipe section 131, the first matching pipe section 131 is communicated with the air inlet cavity 132, and the second sealing section 212 is in sealing fit with the air inlet cavity 132. Air from the air inlet 110 flows from the first mating segment 131 to the air inlet chamber 132 and from the air inlet chamber 132 through the delivery channel 150 into the bladder to inflate the bladder.

The air inlet valve rod 210 is in the first position or the second position, the second sealing section 212 is in sealing fit with the air inlet cavity 132, that is, the second fitting pipe section 133 is not communicated with the air inlet cavity 132 all the time, so that air in the air inlet cavity 132 and the air bag is prevented from leaking from the second fitting pipe, and stability of the seat adjusting valve in use is improved.

A first sealing ring 214 may be disposed between the first sealing section 211 and the air intake rod 213, where the first sealing ring 214 seals between the first sealing section 211 and the air intake cavity 132 when the air intake valve stem 210 is in the first position, so as to avoid leakage of the air in the first mating pipe section 131 into the air intake cavity 132.

The outer wall of the second sealing section 212 may be sleeved with a second sealing ring 215, and the second sealing ring 215 seals between the second sealing section 212 and the second matching pipe section 133, so as to avoid leakage of gas in the gas inlet cavity 132 from the second matching pipe section 133.

In some embodiments, the vent control valve may include a vent stem 220, referring to fig. 4, the vent stem 220 includes third and fourth seal segments 221 and 222 spaced apart in a direction parallel to an axis of the vent stem 220, and a vent stem body 223 connecting the third and fourth seal segments 221 and 222.

Referring to fig. 5, the exhaust passage 140 may include a third fitting pipe section 141, an exhaust chamber 142, and a fourth fitting pipe section 143 sequentially disposed in a direction parallel to an axis of the exhaust valve stem 220, and referring to fig. 4 and 5, a third sealing section 221 is provided through the third fitting pipe section 141, one end of the third fitting pipe section 141 is communicated with the exhaust chamber 142, the other end is communicated with the exhaust port 120, a fourth sealing section 222 is provided through the fourth fitting pipe section 143, an exhaust rod body 223 is provided through the exhaust chamber 142, and the exhaust chamber 142 is communicated with the delivery passage 150.

The exhaust valve stem 220 has a third position and a fourth position, and when the exhaust valve stem 220 is in the third position (refer to fig. 4), the third sealing section 221 and the fourth sealing section 222 are in sealing engagement with the exhaust chamber 142, that is, the third engagement section 141 and the fourth engagement section 143 are not in communication with the exhaust chamber 142, and the exhaust chamber 142 is not in communication with the exhaust port 120 because the exhaust chamber 142 is not in communication with the third engagement section 141, so that air in the air bag cannot flow in a direction from the delivery passage 150, the exhaust chamber 142, the third engagement section 141 and the exhaust port 120, and air in the air bag cannot be exhausted from the exhaust port 120.

Since the fourth mating segment 143 and the vent lumen 142 are not conductive, air within the bladder is also unable to flow in a direction from the delivery channel 150, the vent lumen 142, and the fourth mating segment 143. That is, when the exhaust valve stem 220 is in the third position, air within the airbag cannot be exhausted from the exhaust port 120 and cannot leak from the fourth mating segment 143.

When the exhaust valve rod 220 moves to the fourth position along the direction from the fourth matching pipe section 143 to the third matching pipe section 141, the third matching pipe section 141 is communicated with the exhaust cavity 142, the fourth sealing section 222 is in sealing fit with the exhaust cavity 142, the conveying channel 150, the exhaust cavity 142, the third matching pipe section 141 and the exhaust port 120 are communicated, and air in the air bag is sequentially exhausted from the exhaust port 120 to the outside of the valve body through the conveying channel 150, the exhaust cavity 142, the third matching pipe section 141 and the exhaust port 120 so as to deflate the air bag.

When the airbag on the seat needs to be inflated, the exhaust valve rod 220 is controlled to be in the third position, and the air inlet valve rod 210 is controlled to be in the second position; when it is desired to partially or completely exhaust the air within the bladder, the inlet valve stem 210 is controlled to a first position and the outlet valve stem 220 is controlled to a fourth position.

A third sealing ring 224 may be disposed between the third sealing segment 221 and the vent stem 223, where the third sealing ring 224 seals between the third sealing segment 221 and the vent lumen 142 when the vent stem 220 is in the third position to prevent gas in the vent lumen 142 from leaking from the third mating tube segment 141.

The outer wall of the fourth sealing section 222 may be sleeved with a fourth sealing ring 225, and the fourth sealing ring 225 seals between the fourth sealing section 222 and the fourth mating pipe section 143 to avoid leakage of gas in the exhaust chamber 142 from the fourth mating pipe section 143.

In some embodiments, the user may manually control the inlet valve stem 210 to switch between the first and second positions, and may manually control the outlet valve stem 220 to switch between the third and fourth positions, to make the seat adjustment valve more simple in construction.

Of course, in other embodiments, the inlet control valve may also include an inlet stem reset member, which may include an inlet stem reset spring or an inlet stem reset resilient band, disposed between the inlet stem 210 and the valve body, the inlet stem reset member configured to reset the inlet stem 210 from the second position to the first position. The first position is the initial position of the air inlet valve rod 210, when the air bag needs to be inflated, a user can manually apply external force to the air inlet valve rod 210 to enable the air inlet valve rod 210 to be switched from the first position to the second position, after inflation is completed, after the external force applied to the air inlet valve rod 210 is relieved by the user, the air inlet valve rod 210 is reset to the first position from the second position by the air inlet valve rod resetting piece, so that air of the air inlet 110 is prevented from continuously flowing to the air bag, and the air inlet valve rod 210 is reset by the air inlet valve rod resetting piece, so that the air bag is more convenient and rapid.

In the implementation mode that the air inlet valve rod reset piece comprises an air inlet valve rod reset spring, the air inlet valve rod reset spring can be arranged on the first matching pipe section 131, a space is reserved between one end of the first sealing section 211, which is away from the air inlet cavity 132, and one end of the first matching pipe section 131, which is away from the air inlet cavity 132, the air inlet valve rod reset spring is arranged in the space, one end of the air inlet valve rod reset spring is abutted with the first sealing section 211, and the other end of the air inlet valve rod reset spring is abutted with the valve body. When the air inlet valve rod 210 is located at the second position, the air inlet valve rod reset spring is extruded, and after the external force applied to the air inlet valve rod 210 is released, the air inlet valve rod 210 is reset from the second position to the first position by the elastic force of the air inlet valve rod reset spring.

Likewise, the exhaust control valve may further include an exhaust valve stem reset member, which may include an exhaust valve stem reset spring or an exhaust valve stem reset elastic band, disposed between the exhaust valve stem 220 and the valve body, the exhaust valve stem reset member being configured to reset the exhaust valve stem 220 from the fourth position to the third position. The third position is an initial position of the exhaust valve rod 220, when the air in the air bag needs to be partially or completely exhausted, a user can manually apply an external force to the exhaust valve rod 220 to switch the exhaust valve rod 220 from the third position to the fourth position, after the exhaust is completed, the user releases the external force applied to the exhaust valve rod 220, and after the exhaust is completed, the exhaust valve rod resetting piece resets the exhaust valve rod 220 from the fourth position to the third position, so that the air in the air bag is prevented from being continuously exhausted from the exhaust port 120, and the exhaust valve rod 220 is reset through the exhaust valve rod resetting piece, so that the air bag is more convenient and quick.

In the implementation manner that the exhaust valve rod resetting piece comprises an exhaust valve rod resetting spring, the exhaust valve rod resetting spring can be arranged on the fourth matching pipe section 143, a space is reserved between one end of the fourth sealing section 222, which is away from the exhaust cavity 142, and one end of the fourth matching pipe section 143, which is away from the exhaust cavity 142, the exhaust valve rod resetting spring is arranged in the space, one end of the exhaust valve rod resetting spring is in butt joint with the fourth sealing section 222, and the other end of the exhaust valve rod resetting spring is in butt joint with the valve body. When the exhaust valve rod 220 is positioned at the fourth position, the exhaust valve rod return spring is pressed, and after the external force applied to the exhaust valve rod 220 is released, the elastic force of the exhaust valve rod return spring returns the exhaust valve rod 220 from the fourth position to the third position.

Referring to fig. 4 and 5, in some embodiments, the transfer passage 150 may include a first connection passage 151 and a second connection passage 152, one end of the first connection passage 151 communicating with the intake passage 130, and the other end of the first connection passage 151 communicating with the exhaust passage 140; one end of the second connection channel 152 communicates with the first connection channel 151, and the other end communicates with the balloon. When the airbag is inflated, gas from the gas inlet passage 130 flows from the first connection passage 151 to the second connection passage 152, and from the second connection passage 152 to the inside of the airbag. When the airbag is exhausted, the gas in the airbag flows from the second connection passage 152 to the first connection passage 151, flows from the first connection passage 151 to the exhaust passage 140, and finally is exhausted from the exhaust port 120.

In an implementation where the intake passage 130 includes the first mating pipe segment 131, the intake chamber 132, and the second mating pipe segment 133, and the exhaust passage 140 includes the third mating pipe segment 141, the exhaust chamber 142, and the fourth mating pipe segment 143, one end of the first connection passage 151 communicates with the intake chamber 132, and the other end communicates with the exhaust chamber 142. When the airbag is inflated, air flows from the first mating segment 131 to the air intake chamber 132, then flows through the first connecting channel 151 and the second connecting channel 152 in order, and flows from the second connecting channel 152 into the airbag. When the airbag is exhausted, the gas in the airbag flows from the second connection passage 152 to the first connection passage 151, and sequentially flows from the first connection passage 151 to the exhaust chamber 142 and the third fitting tube section 141, and finally is exhausted from the exhaust port 120.

In some embodiments, the seat adjusting valve further includes a plurality of keys 30, and each of the intake control valve and each of the exhaust control valves is provided with a key 30. When the airbag needs to be inflated, the air inlet control valve is switched from the first position to the second position by pressing the key 30 corresponding to the air inlet control valve, so that the air inlet 110 is communicated with the conveying channel 150, and the air in the air inlet 110 can flow into the airbag.
