[0026] The following will further describe the specific embodiments of the present invention in conjunction with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] This embodiment provides a magnetic levitation balancing vehicle, which is a specific application of the innovative solution of the present invention on a balancing vehicle. The innovative solution of the present invention can also be applied to traveling devices such as scooters.

[0028] like Figure 1-4 As shown, the balancing vehicle includes a vehicle body 100 and a footrest 200. The vehicle body 100 is provided with a first magnet 110, and the footrest 200 is provided with a second magnet 210. The first magnet 110 and the second magnet 210 are arranged to repel each other. Due to the repulsion between the first magnet 110 and the second magnet 210, the footrest 200 is suspended relative to the vehicle body 100, leaving a gap between the footrest 200 and the vehicle body 100. When a user steps on the footrest 200, uneven road conditions cause the vehicle body 100 to vibrate. The vibration of the vehicle body 100 causes the gap between the footrest 200 and the vehicle body 100 to change, thereby reducing the amplitude of the up and down vibration of the footrest 200, improving the stability of the footrest 200, reducing the impact of the vibration of the vehicle body 100 on the human body, and improving riding comfort.

[0029] The self-balancing vehicle includes a wheel 300 with a hub motor, a battery and a controller installed in the vehicle body 100. The vehicle body 100 is a non-rotatable structure. An angle sensor is installed on the footrest 200. The angle sensor can be a gyroscope or a level. The angle sensor detects changes in the tilt angle of the footrest 200 and wirelessly transmits the tilt angle information of the footrest 200 to the controller, so that the controller controls the forward movement and steering of the self-balancing vehicle. In other optional embodiments, the self-balancing vehicle can also be a twist-type self-balancing vehicle, that is, the vehicle body 100 includes two parts that can swing relative to each other. In this case, the angle sensor can be installed in the vehicle body 100.

[0030] like Figure 3 As shown, the vehicle body 100 has a groove 120, and the footrest 200 is arranged corresponding to the groove 120; the sidewalls of the groove 120 can form a lateral constraint on the footrest 200 to prevent the footrest 200 from being separated from the corresponding position of the vehicle body 100. In other optional embodiments, the upper surface of the vehicle body 100 is a flat surface.

[0031] like Figure 3As shown, the groove 120 has an upwardly inclined sidewall, and the footrest 200 has an inclined wall corresponding to the inclined sidewall. The inclined sidewall and the inclined wall facilitate the rapid alignment of the footrest 200 into the groove 120. In other optional embodiments, the sidewalls of the groove 120 and the corresponding sidewalls of the footrest 200 may also be vertical walls.

[0032] like Figure 3 As shown, the first magnet 110 is installed obliquely on the side wall of the groove 120, so that the first magnet 110 has an upward force and a horizontal force on the second magnet 210, and the upward force is balanced with the sum of the human body's gravity and the pedal's gravity. The side wall of the groove 120 is annular, and the horizontal force of the first magnet 110 on the second magnet 210 at various angles also tends to be balanced, so that the position of the pedal member 200 relative to the vehicle body 100 in the horizontal direction is relatively stable, preventing the pedal member 200 from separating from the vehicle body 100.

[0033] In other optional embodiments, the first magnet 110 may be installed only at the bottom of the groove 120, and the second magnet 210 may be correspondingly installed at the bottom of the footrest 200. In still other optional embodiments, the first magnet 110 may be installed at both the groove wall and the bottom of the groove 120, and the second magnet 210 may be installed at corresponding positions on the footrest 200. In this embodiment, the first magnet 110 corresponding to the side wall of the groove 120 may be vertically arranged to provide only horizontal force on the footrest 200, while the upward force is provided by the first magnet 110 located at the bottom of the groove 120.

[0034] The first magnet 110 includes a first upper magnet 211 and a second upper magnet 212, and the second magnet 210 includes a first lower magnet 111 and a second lower magnet 112. The first upper magnet 211 and the first lower magnet 111 are arranged to repel each other with their north poles, and the second upper magnet 212 and the second lower magnet 112 are arranged to repel each other with their south poles. When the balancing car needs to be stored, the first upper magnet 211 and the second lower magnet 112 are aligned, and the second upper magnet 212 and the first lower magnet 111 are aligned, which will form an attractive force, so that the footrest 200 can be adsorbed on the car body 100 under the action of magnetic force, which facilitates the overall storage of the balancing car and reduces the risk of losing the footrest 200. In this embodiment, the first upper magnet 211 and the second upper magnet 212 are respectively installed on two different footrests 200.

[0035] The first magnet 110 is an electromagnet, and the second magnet 210 is a permanent magnet. In other optional embodiments, the first magnet 110 and the second magnet 210 can both be permanent magnets, or both the first magnet 110 and the second magnet 210 can be electromagnets, or the first magnet 110 can be a permanent magnet and the second magnet 210 can be an electromagnet. When the second magnet 210 is an electromagnet, a battery is provided on the pedal 200 to connect to the second magnet 210, or an inductive coupling coil is provided on both the vehicle body 100 and the pedal 200 to enable the battery in the vehicle body 100 to power the second magnet 210, and no tangible connection structure is required between the pedal 200 and the vehicle body 100.

[0036] like Figure 3 As shown, the groove 120 is polygonal in shape. The first magnet 110 includes multiple independent magnetic units disposed on the sidewalls corresponding to each side of the groove 120. The footrest 200 is polygonal in shape corresponding to the groove 120. This allows the force exerted by each magnetic unit on the footrest 200 to be controlled by individually adjusting the magnetic field strength of each magnetic unit. For example, when the magnetic field strength of the magnetic unit on the left side of the groove 120 increases relative to the magnetic unit on the right side, the footrest 200 moves rightward relative to the vehicle body 100, allowing the horizontal position of the footrest 200 to be adjusted. This adjustment can be made by providing a corresponding button on the vehicle body 100 or by equipping the balancing vehicle with a corresponding remote control. This allows the spacing between the two footrests 200 to better accommodate users of different heights and facilitates users to find the most suitable stepping distance for their needs. Magnetic units may also be disposed at the bottom of the groove 120 to balance the vertical force exerted on the footrest 200. The polygon in this embodiment is a regular hexagon. In other alternative embodiments, the polygon may also be a square, rectangle, octagon, or other shape.

[0037] In other optional embodiments, the groove 120 is circular, and the pedal member 200 is circular corresponding to the groove 120 .

[0038] like Figure 3-4 As shown, the footrest members 200 include two, each of which has a footrest area, and the grooves 120 are two and correspond to the two footrest members 200, so as to reduce the interference between the two footrest members 200. In other optional embodiments, such as Figure 5 As shown, the groove 120 can also be one corresponding to two footrest members 200. In addition, the footrest member 200 can also be one, and the footrest member 200 has two footrest areas, that is, two feet step on the same footrest member 200.
