[0049] The movable plate 3, the fixed plate 2 and the movable plate 3 are movably sleeved on the guide rod 101, and the elastic unit 4 is arranged between the fixed plate 2 and the movable plate 3, and the elastic unit 4 is used for pushing the fixed plate 2 and the movable plate 3 away from each other;

[0050] The driving unit 11 is arranged on the mounting seat 1, and the driving unit 11 is used for driving the movable plate 3 to be close to the fixed plate 2 to complete the locking with the fixed plate 2.

[0052] For example, the mounting bracket 102 is arranged on the mounting seat 1, the guide rod 101 is arranged on the mounting seat 1 and the mounting bracket 102 respectively, the mounting bracket 102 and the mounting seat 1 are provided with a clamping area, the fixed plate 2 and the movable plate 3 are located in the clamping area, and the driving unit 11 is arranged on the mounting bracket 102.

[0053] It should be further pointed out that the purpose of arranging the mounting bracket 102 is to provide a mounting position for the driving unit 11 and limit the movement range of the fixed plate 2 and the movable plate 3.

[0054] For example, the elastic unit 4 is a V-shaped spring, the elastic unit 4 is arranged on the mounting seat 1, one end of the elastic unit 4 abuts against the fixed plate 2, and the other end of the elastic unit 4 abuts against the movable plate 3.

[0058] It also needs to be explained that the motor in the application provides power for the rotation of the driving screw, and the axial movement of the driving screw is realized through the threads on the outer wall of the driving screw and the screw hole. The screwing manner makes the axial movement of the driving screw more stable and accurate, and ensures that the clamping effect of the fixed plate 2 and the movable plate 3 can be effectively realized when the movable plate 3 is pressed.

[0059] It is further explained that the driving screw is separated from the movable plate 3 because the movable plate 3 is prevented from rotating with the rotation of the driving screw. In order to ensure the clamping effect of the fixed plate 2 and the movable plate 3, it is necessary to increase the contact area of the movable plate 3 and the rotating plate 6. However, when the area of the movable plate 3 is large, it will occupy a large space when rotating with the driving screw. Therefore, it is necessary to prevent the movable plate 3 from rotating during the pressing process.

[0060] Exemplarily, the motor is fixed on the mounting bracket 102 by bolts.

[0061] Exemplarily, the elastic unit 4 is provided with mounting holes at both ends, the fixed rod passes through the two mounting holes, one end of the fixed rod is arranged on the mounting seat 1, and the other end of the fixed rod is arranged on the mounting bracket 102.

[0067] Exemplarily, the rotating plate 6 is a fan-shaped structure, and the outer edge of the rotating plate 6 extends into the fixed plate 2 and the movable plate 3.

[0068] In the application, the rotating support 10 is connected with the rotating plate 6 and rotates coaxially.

[0069] It also needs to be explained that the rotating plate 6 is a fan-shaped structure, so that the outer edge of the rotating plate 6 can be located between the fixed plate 2 and the movable plate 3 at any angle when the rotating plate 6 rotates.

[0070] Exemplarily, the rotating plate 6 is also provided with a weight-reducing hole.

[0071] It also needs to be explained that the purpose of arranging the weight-reducing hole is to reduce the weight of the rotating plate 6.

[0072] Exemplarily, the connecting piece 9 includes a frame connecting part and a wheel connecting part, the frame connecting part is connected with the corresponding end of the rotating plate 6, the wheel connecting part is connected with the corresponding fixed support 701, and the frame connecting part and the wheel connecting part are connected through a compression spring.

[0073] It also needs to be explained that the purpose of arranging the compression spring is that when the vehicle drives through uneven road surface, the shock-absorbing spring can absorb the energy brought by bumping, reduce the violent shaking of the vehicle body, quickly absorb the vibration, make the vehicle restore the normal driving state as soon as possible, and effectively reduce the impact of the impact force on the vehicle and the passengers.

[0074] Exemplarily, the connecting piece 9 also includes a piston rod and a cylinder barrel, the piston rod is fixed on the frame connecting part, the cylinder barrel is fixed on the wheel connecting part, the piston rod is movably arranged in the cylinder barrel, and the compression spring is sleeved outside the piston rod and the cylinder barrel.

[0076] Exemplarily, the connecting piece 9 and the frame 7 are connected through a ball hinge.

[0077] It should be noted that the ball hinge connection allows the connecting piece 9 to adjust the position of the two ends of the rotating plate 6 during rotation, avoiding mechanical damage between the connecting piece 9 and the frame 7 due to changes in the position of the wheel 8.

[0078] For example, the connecting piece 9 and the fixed support 701 are connected by a ball hinge.

[0079] It should be noted that the ball hinge between the connecting piece 9 and the fixed support 701 allows the connecting piece 9 to shift without affecting the hinge between the connecting piece 9 and the fixed support 701 during rotation of the rotating plate 6.

[0080] For example, two power motors are provided on the frame 7, and the power motors drive the corresponding wheels 8 respectively.

[0081] It should be noted that two power motors are provided on the frame 7 in the present application, and the power motors are provided on the bottom plate of the frame, so that one power motor can drive one wheel 8, and the two wheels 8 can operate at different speeds. The dual-motor drive system can independently control the speed and torque of each wheel, thereby more accurately adjusting the driving attitude of the vehicle. In complex road conditions, such as turning or driving on uneven road surfaces, the dual-motor drive system can better maintain the stability and maneuverability of the vehicle. According to the driving conditions of the vehicle and the needs of the driver, the dual-motor drive system can dynamically adjust the output power and torque distribution of each motor. This dynamic adjustment helps to reduce energy loss and improve energy utilization efficiency, thereby prolonging the cruising range of the vehicle.

[0082] For example, the center lines of the rotating shafts of the two fixed supports 701 are arranged in line with the center lines of the output shafts of the two power motors.

[0083] It should be noted that in the present application, the center lines of the rotating shafts of the two fixed supports 701 are arranged in line with the center lines of the output shafts of the two power motors. When the wheel 8 rotates relative to the frame 7, the distance between the wheel 8 and the power motor on the frame 7 does not change, which does not affect the transmission distance between the power motor and the corresponding wheel 8, and does not cause transmission failure due to rotation of the wheel 8.
