Therefore, the entire electric balance vehicle 100 will be stronger and stronger, and also protect the electronic components therein, so that the operation of the electric balance vehicle 100 is more stable and the service life is longer. Preferably, the inner cover 2 is an aluminum alloy, so the strength is higher and the structure is more stable. The top cover 1 and the bottom cover 3 are plastics, which can reduce the weight of the entire vehicle body, and also facilitate the process of spraying and coloring the appearance of the vehicle body, and produce anti-fouling and waterproof effects. The conventional electric balance car has no inner cover 2, and the internal electronic components directly bear the weight of the user, and because the balance car travels when it is swaying, it is easy to automatically turn off the power, and the user is easy to use. A fall occurred. The electric balance car 100 of the present invention solves the technical problem precisely.

The rotation mechanism 60 is fixed to the middle of the first inner cover 21 and the second inner cover 22. In the first embodiment, the rotating mechanism 60 includes two bearings 61, a bushing 62 and two retaining springs 63. The two bearings 61 are fixed to the inner ends of the first inner cover 21 and the second inner cover 22, respectively. The sleeve 62 is fixed in the two bearings 61 and fixed to the inner cover 2 via a snap spring 63, so that the left and right inner covers of the inner cover 2 can be rotated by the cooperation of the rotating mechanism 60. By providing such a rotating mechanism 60, the two parts of the body of the electric balance vehicle 100 can freely rotate relative to each other.

In order to mount the above-described rotating mechanism 60, a cylindrical cylinder 24 may be designed at the inward end of the first inner cover 21 and the second inner cover 22, and the bearing 61 and the sleeve 62 are mounted from the outside to the inside through the retaining spring 63. Inside the cylinder 24. In order to limit the relative rotation angle between the first inner cover 21 and the second inner cover 22, the electric balance vehicle 100 further includes a limiting shaft 7, and the length of the limiting shaft 7 in the second inner cover 22 It is longer than the length inside the first inner cover 21. In the present embodiment, the limiting shaft 7 is located between the inward ends of the first inner cover 21 and the second inner cover 22.

Two wheels 50 are rotatably fixed to both sides of the inner cover 2, and the two hub motors 4 are respectively fixed in the two wheels 50. The hub motor 4, also known as the wheel-mounted motor, integrates the power, transmission and braking devices into the hub, thus omitting a large number of transmission components, making the structure of the balancer simpler, achieving better space utilization, and at the same time transmitting Efficiency is improved. Since the hub motor 4 has the characteristics of independent driving of a single wheel, the differential steering of a similar track type vehicle can be realized through different speeds or even reverse rotations of the left and right wheels 50, thereby greatly reducing the turning radius of the vehicle, and in a special case, almost in situ can be realized. Turn.

A plurality of sensors 80 are disposed between the bottom cover 3 and the inner cover 2. Specifically, half of the sensor 80 is disposed between the first bottom cover 31 and the first inner cover 21, and the other half of the sensor 80 is disposed between the second bottom cover 32 and the second inner cover 22. The power source 81 is fixed between the first bottom cover 31 and the first inner cover 21. The controller 82 is fixed between the second bottom cover 32 and the second inner cover 22. This creation requires only one power source 81 and one controller 82 to simultaneously control the two hub motors 4, which is simpler to assemble, more convenient in wiring, and convenient for returning to the factory after the electric balancer 100 is sold. Moreover, the power source 81 and the controller 82 are respectively disposed in the two halves of the vehicle body, which is more space-saving and makes the structure of the entire vehicle body more compact. The wires connecting the power source 81 and the controller 82 and the wires connecting the controller 82 and the hub motor 4 can be passed through the joints of the two halves of the vehicle body, that is, from the left half (or the right half) of the vehicle body. Go to the right half (or the left half).

In the present embodiment, the sensor 80 includes a gyroscope 83, an inductive switch 84, and an acceleration sensor 85. In the actual application, in order to modularize the internal components of the entire device, the acceleration sensor 85 and the gyroscope 83 are disposed on the same circuit board. Fig. 2 shows only the front side of the board due to the viewing angle, and the acceleration sensor 85 and the gyroscope 83 (shown by broken lines in Fig. 2) are disposed on the back side of the board in actual use. The controller 82 is electrically connected to the plurality of sensors 80, the power source 81 and the hub motor 4. The controller 82 controls the corresponding hub motor 4 to drive the corresponding wheel 50 to rotate according to the sensing signal transmitted by the sensor 80.

The sensor switch 84 senses whether the user is standing on the electric balance vehicle 100 to be turned on or off, the controller 82 receives the sensing signal of the sensor switch 84 (ie, turns the signal on or off) to control whether the hub motor 4 is working, and the controller 82 receives the acceleration. The sensing signals of the sensor 85 and the gyroscope 83 are used to control whether the hub motor 4 changes state. In the first embodiment, the inductive switch 84 It is an infrared light sensor. However, this creation does not impose any restrictions on this. In other embodiments, the inductive switch 84 can be a microwave inductive switch, an ultrasonic inductive switch, or any other inductive switch that performs the same function. In the present embodiment, the electric balance vehicle 100 further includes a blocking member 86. When the user steps on the pedal 5, the blocking member 86 blocks the infrared sensing area of the infrared photodetector, and the infrared photodetector is thus turned on. The controller 82 receives the turn-on signal from the inductive switch 84, thereby driving the hub motor 4 to operate.

The balance car of the prior art is that the wheel starts to rotate once the wheel is turned on, and the user cannot easily stand on the balance car. When the user comes down from the balance car, the wheel does not stop rotating, the whole wheel must be pressed to stop the rotation, which has a very large potential danger and is very inconvenient to use. The electric balance vehicle 100 of the present embodiment does not operate as a starting hub motor 4, but drives the wheel 50 by sensing whether the user stands on the pedal 5, thereby avoiding the blind rotation of the balance vehicle in the prior art. Increased security of use. On the other hand, the electric balance vehicle 100 of the present embodiment balances the automatic balance after sensing the pedaling, instead of balancing the power supply, ensuring the safety of the vehicle body, and the rotation of the vehicle body is small, so as to avoid immediately after the power is turned on in the prior art. Self-balancing will cause the car body balance point to be incorrect, and the car body rotation may cause the user to be unable to balance.

The acceleration sensor 85 and the gyroscope 83 collectively detect the motion state of the balancer 100, such as detecting the acceleration and angular velocity of the balancer 100, and the like. The controller 82 drives the hub motor 4 based on the sense signals transmitted by the acceleration sensor 85 and the gyroscope 83 to determine whether the balancer 100 is to change direction or speed. The detection techniques of the acceleration sensor 85 and the gyroscope 83 are conventional techniques and will not be described herein.

In the present embodiment, the electric balance vehicle 100 further includes a U-shaped fixing member 9. Both the sensor 80 and the blocking member 86 are fixed to the U-shaped fixing member 9, so that the mounting of the electronic components of the entire device is modularized, facilitating assembly, wiring, and later maintenance.

In use, the user uses the force of the foot to drive a part or both parts of the vehicle body to twist together, so that the sensor 80 sends a sensing signal to the controller 82, and the controller 82 drives the hub motor 4 according to the internal control program. In turn, the user can turn, move forward or backward, thus achieving "foot control", which is more convenient to use and more flexible in control.

How the controller 82 of the present invention controls the balance car to reach the self-balancing state and controls the advancement, retreat or turning of the wheel 50 is a conventional technique, and details are not described herein. Specific reference Test the current method of balancing car control and the control technology adopted by various balance car manufacturers. For example, the Chinese patent application No. 201320050547.3, the patent name is "smart balance balance control device and smart balance car", this control device can be the controller 82 in this embodiment. Or, as described in Chinese Patent Application No. 201220367045.9, the patent name is "the circuit control device for controlling the balance car motor using the CPLD". Of course, in practical applications, other control devices and control methods may also be selected, such as Chinese Patent Application No. 201310516158.X, and the patent name is "the control method described in the two-wheel self-balancing vehicle control method".

In the embodiment, the electric balance vehicle 100 further includes a charging interface 87, and the charging interface 87 is disposed on the bottom cover 3. Specifically, the charging interface 87 is disposed outside the bottom cover 3 to facilitate charging of the power source 81.

In the present embodiment, the controller 82 has a storage unit 821 that stores the initial balance state of the electric balance vehicle 100 and a correction unit 822 that corrects the current balance state of the electric balance vehicle 100. Specifically, when the electric balance vehicle 100 is shipped from the factory, the storage unit 821 records the data of the vehicle body level. When the electric balance vehicle 100 is used for a period of time, the sensor 80 of the electric balance vehicle 100 may be offset due to the use of the external environment such as temperature and the like, and thus the horizontal reference value of the electric balance vehicle 100 may change accordingly. . At this time, if the horizontal level data at the factory is still used, the control balance vehicle 100 may be inaccurate, long-term use or even an accident. The correcting unit 822 of this embodiment stores a correction program. When the calibration program is run, the electric balance vehicle 100 detects the immediate condition of the sensor 80 and judges and compares the initial level data to determine whether the original data is to be overwritten for re-setting. By setting the calibration program, the control precision and service life of the balance vehicle 100 are greatly improved, and the problem of the flexibility and accuracy of the balance vehicle after using the balance vehicle for a period of time is overcome.

Fig. 6 is a schematic view showing an electric balance vehicle according to a second embodiment of the present creation. Please refer to Figure 6. The only difference between the electric balance vehicle 200 in the second embodiment and the electric balance vehicle 100 in the first embodiment is that the electric balance vehicle 200 further includes a remote controller 210 that receives a control signal from the remote controller 210. Remote control of the electric balancer 200 can be achieved by providing the remote controller 210. The power button and the correction button can be set on the remote controller 210, and the present invention does not limit this. The electric balance car 200 further includes an interface cover 220, and the interface cover 220 covers the charging interface. The interface cover 220 prevents the muddy water splashed by the electric balance vehicle 200 from contaminating the charging interface or even entering the interior of the vehicle body.
