DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Example 1

[0021] like Figure 1-4 As shown, a flat fork structure with auxiliary support function includes an electric vehicle flat fork 1, which is a rear flat fork of a two-wheeled vehicle or a three-wheeled vehicle, a parallel axis gear reduction box 3 is connected to the outer side of the flat fork 1 through fasteners, a parallel axis gear motor 2 is installed on the inner side of the flat fork 1, and a support leg 4 is connected to the output shaft of the outer side of the parallel axis gear box 3 through fasteners, and a roller 5 is installed on the support leg 4.

[0022] A worm gear reduction box 23 is provided at the front end of the parallel axis gear motor 2. A pinion shaft 21 is provided at the front end of the worm gear reduction box 23, and a cover plate 22 is provided at the rear side thereof. The worm gear reduction box 23 is provided with 8 fixed threaded holes on its outer surface to adjust and fix the angle of the parallel axis gear motor 2.

[0023] The parallel axis gear motor 2 and the flat fork 1 are fixed by fasteners. The flat fork 1 is provided with four annular grooves to facilitate the parallel axis gear motor 2 to be rotated to a suitable position and then fixed on the flat fork 1.

[0024] A worm gear reduction box 23 is provided in the parallel axis gearbox 3, and the worm gear teeth 24 are located in the worm gear reduction box 23. A pinion shaft 21 is provided on one side of the worm gear teeth 24. One side of the pinion shaft 21 is interference fitted on the flat fork 1 through a sleeve A31, and a fan gear 34 is provided below it. The front and rear raised shafts of the fan gear 34 rotate in the reduction box 3 through sleeves B32 and sleeves C33. Sleeves A31 and sleeves B32 are interference fitted on the flat fork 1 and the box cover 35 respectively.

[0025] Shock absorption limiter A36 and shock absorption limiter B37 are respectively provided on both sides of the box cover 35. They limit the rotation angle of the sector gear 34 to ensure that the sector gear 34 can be limited when rotating to the left or the right side.

[0026] Working process: when parking is required, turn off the car key, the controller receives the shutdown signal, and drives the left and right self-locking motors to work through the set program and current. The left and right self-locking motors simultaneously drive the fan gear 34 to make the 5 rollers on the auxiliary support leg 4 touch the ground. When the rollers 5 on the left and right auxiliary support legs 4 touch the ground, the current increases, triggering the set anti-rotation current, and the left and right self-locking motors stop working, giving priority to maintaining the auxiliary support state to make the vehicle body safe and stable. When a person gets off the vehicle, the pressure switch or micro switch is triggered, and the left and right self-locking motors drive the fan gear 34 to make its end contact the shock-absorbing limit A36. The current increases, triggering the set anti-rotation current, the motor stops working, the left and right auxiliary support legs 4 touch the ground and stand upright, the roller 5 is suspended in the air, and the wheels leave the ground to complete parking.

[0027] When it is necessary to switch to the auxiliary support state, the key is turned on and the mode button is pressed once. The left and right self-locking motors simultaneously drive the sector gear 34 to make the auxiliary support leg 4 work, and the roller 5 slides to the set auxiliary support state to keep the vehicle body safe and stable.

[0028] When it is necessary to switch to the folded state, you need to press the mode button once, or switch to the semi-automatic mode, and fold the auxiliary support leg 4 manually or automatically through wheel speed sensing. The left and right motors drive the fan gear 34 and the auxiliary support leg 4 to work at the same time. When the end of the fan gear 34 contacts the shock-absorbing limiter A36, the current increases, and the left and right motors stop working through the set anti-rotation current, completing the folding of the auxiliary support leg 4.

[0029] When the vehicle is parked on a bumpy and uneven road and needs assistance, it is necessary to press the mode button once, and the left and right self-locking motors drive the fan gears 34 to make the left and right supporting legs 4 work. Regardless of whether the left roller or the right roller touches the ground first, the current increases, and the left self-locking motor or the right motor stops working through the set blocking current. When the angle sensor senses that the vehicle body is not at the set horizontal angle, the left and right self-locking motors cooperate to drive the fan gears 34 through the set program to adjust the supporting legs 5 forward and backward to the horizontal angle set by the angle sensor (electronic gyroscope).

[0030] When the vehicle is parked on an uneven or bumpy road, the key is turned off, the controller receives a signal, and the left and right self-locking motors drive the sector gears 34 to make the left and right support legs 4 work. Regardless of whether the left roller or the right roller touches the ground, the current increases, and the left self-locking motor or the right self-locking motor stops working through the set resistance current. When the angle sensor (electronic gyroscope) senses that the vehicle body is not at the set horizontal angle value, the left and right self-locking motors cooperate to drive the sector gears 34 through the set program, so that the support legs 4 are adjusted forward and backward to the horizontal angle value set by the angle sensor (electronic gyroscope), with priority given to the left and right self-locking motors. The vehicle is kept in an auxiliary support state. When a person gets off the vehicle, the pressure switch or micro switch is triggered, and the left and right self-locking motors drive the fan gear 34 to make its end contact the shock-absorbing limit B37. The current increases, triggering the set anti-rotation current. At the same time, the angle sensor (electronic gyroscope) works together. If the angle is not at the set horizontal angle value, the left self-locking motor or the right self-locking motor will work independently through the set program to drive the fan gear 34 to move the support leg 4 to the horizontal angle value set by the angle sensor, that is, parking is completed, so that the vehicle always remains safe, stable and anti-theft.
