[0020] 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.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, a quick installation and disassembly device for the side-mounted motor bracket of an electric motorcycle includes a frame-body connecting device and a motor mounting device connected thereto, the motor mounting device is provided with a side-mounted motor assembly cavity 5 for assembling the side-mounted motor, the frame-body connecting device includes a body base 10, the middle part of the body base 10 is plugged into the connecting device plug 14 through a slot 15, a switch buckle 2 and a switch 3 are respectively provided on both sides thereof, a connecting device fixing tongue 8 is provided in the middle part of the slot 15, a spring 7 is provided on the inner wall thereof, and switch connecting devices 9 are provided on both sides of the connecting device fixing tongue 8.

[0023] A reducer cover 6 is connected to the rear of the motor mounting device to prevent the reducer from being invaded by foreign matter or liquid.

[0024] The side-mounted motor hole shaft cavity 4 in the side-mounted motor assembly cavity 5 is used to place the shaft of the side-mounted motor and is connected to the reducer.

[0025] A base body buffer device 13 is provided below the connector plug 14 , and a fixing tongue groove 12 is provided in the middle thereof.

[0026] The vehicle body base 10 is provided with a handle 1 , and the vehicle body base 10 is separated from the vehicle frame by pulling the handle 1 .

[0027] The reducer housing 6 is provided with a wheel connection hole shaft 11 for positioning.

[0028] Working principle: The vehicle body base 10 is fixedly connected to the vehicle body, and the connecting device plug 14 on the vehicle body base 10 is inserted into the slot 15. During the insertion process, since the lower part of the connecting fixing tongue 8 is arc-shaped, the upward force of the connecting device plug 14 will squeeze the spring 7 to shrink backward so that the connecting device plug 14 is inserted into the slot 15. After insertion, the connecting device fixing tongue 8 matches the fixing tongue groove 12. After the connecting device plug 14 enters the slot, the fixing tongue 8 is pushed out by the spring 7 and enters the fixing tongue groove 12. The inner wall of the fixing tongue groove 12 is covered with rubber to reduce friction between the two, reduce wear and alleviate impact and vibration. Since the upper part of the connecting device fixing tongue 8 is flat, When the door lock is assembled with the fixing tongue groove 12, the fixing tongue 8 will not shake even when subjected to external force from the vehicle body base 10, and the connection is fast, firm and reliable. When disassembling, the switch 3 is pulled backward, and the spring 7 and the fixing tongue 8 are forced backward. The switch 3 and the fixing tongue 8 are connected through the switch connecting device 9 and have the freedom of rotation. At this time, the spring is forced backward to pull the fixing tongue 8 backward out of the fixing tongue groove 12. After being in place, the switch 3 can be rotated to the switch buckle 2 due to its rotational freedom. Finally, it can be separated from the vehicle body base 10 by pulling the handle 1. The disassembly and assembly are convenient and quick. The surface of the base body buffer device 13 is covered with rubber, which can effectively reduce the impact of vibration and impact during driving.

[0029] The side-mounted motor is aligned and assembled through the side-mounted motor assembly cavity 5, and the side-mounted motor hole shaft cavity 4 is placed in the shaft of the side-mounted motor to connect with the reducer. The reducer cover 6 prevents foreign matter and liquid from entering the reducer and affecting the working state.
