Detailed Description

The utility model is further described below with reference to specific examples:

an electric cross-country motorcycle comprises a frame 5, wherein the front end of the frame 5 is connected with a front wheel assembly 6, and the rear end of the frame 5 is connected with a rear wheel assembly 7 through a rear bottom fork 8; one end of the shock absorber 4 is fixed on the frame 5, and the other end is fixed on the rear bottom fork 8.

Wherein the rear bottom fork 8 comprises

The front fork part 1 is used for connecting a frame 5 of the electric cross country motorcycle;

the rear fork part 2 is connected with the tail end of the front fork part 1 and is used for connecting a rear wheel assembly 7 of the electric cross country motorcycle;

the connecting pair 3 is arranged in the front fork part 1 and is positioned at the bottom side of the front fork part 1, and a connecting hole 31 is formed in the connecting pair 3;

and one end of the damper 4 is positioned in the connecting hole 31 and hinged with the connecting pair 3.

As shown in fig. 1-3, each of the front fork 1 and the rear fork 2 includes a left fork arm and a right fork arm, and a connection hole 31 is formed at the top of each fork arm for connecting the frame 5 and the rear wheel assembly 7; the front fork part 1 and the rear fork part 2 are integrally formed to form the rear bottom fork.

The connecting pair 3 is also integrally formed between two fork walls of the front fork part 1, and the connecting pair 3 is of a flat plate structure and is fixedly connected with the bottom sides of the fork arms; the reason for arranging the coupling pair 3 on the underside of the yoke is to adapt the length of the shock absorber 4 in order to reduce the height of the coupling pair 3 as much as possible. An oval connecting hole 31 is formed in the connecting pair 3, in the embodiment, hinged seats 32 protrude from the two sides of the lower end face of the connecting pair 3, where the connecting hole 31 is formed, hinged holes are formed in the hinged seats 32, hinged holes are also formed in one end of the shock absorber 4, when the connecting pair is connected, one end of the shock absorber 4 penetrates through the connecting hole 31 to enable the hinged holes in the shock absorber 4 to be opposite to the hinged holes in the hinged seats 32, at the moment, a hinged shaft penetrates through the space between the shock absorber 4 and the hinged seats 32, and one end of the shock absorber 4 is fixed on the hinged seats 32 to achieve connection. The articulated seat 32 is provided to further reduce the connection position of the shock absorber 4 with the rear fork 8 so as to adapt the length of the shock absorber 4 to achieve the best shock absorption effect. According to the utility model, the positions of the connection points of the shock absorber 4 and the rear bottom fork 8 are greatly reduced by the integrally formed connection pair 3 and the hinge seat 32 structure, so that the shock absorber 4 with a longer length is adapted to absorb shock under the condition that the length of the rear bottom fork 8 is not changed; and this patent has got rid of the link structure between bumper shock absorber 4 and the back chain stay 8 to make the distance between bumper shock absorber 4 and the back chain stay 8 set up more accurately. In other embodiments, the hinge seat 32 may not be provided, and the user may fix one end of the shock absorber 4 directly in the connection hole 31 for use.

Further, the front end of the connecting pair 3 is turned upwards, and the connecting hole 31 is located on the turning fold 33. As shown in fig. 2, the folding line 33 is formed transversely and located at the center of the connecting pair 3, and an included angle is formed between the front end of the connecting pair 3 and the rear end of the connecting pair 3 by the folding line 33. The upward folding of the upper end of the connection pair 3 has the effect of obtaining a support point on the folding trace 33 by folding, thereby increasing the support strength of the whole connection pair 3 and further increasing the service life of the whole rear bottom fork 8.

Further, a reinforcing seat 11 is arranged at the rear end of the front fork part 1, and the width of the reinforcing seat 11 is larger than that of the front end of the front fork part 1; the connection pair 3 is arranged between the reinforcing seats 11. As shown in fig. 2, normally, the front and rear end widths of the two fork arms of the front fork part 1 are substantially the same, while the rear end width of the fork arm is significantly larger than the front end width thereof after the reinforcing seat 11 is provided, and a flared shape is formed between the two fork arms by the reinforcing seat 11. The purpose of setting up and strengthening seat 11 is in order to increase the inboard width of front fork portion 1 to connect through front fork portion 1 is inboard the vice 3 of connection, thereby increase overall structure's steadiness, prevent that back chain stay 8 from splitting or the vice 3 department of connection from splitting when the vehicle traveles.

Further, the bottom of the back fork part 2 is provided with a plurality of hangers 21 for connecting chain guides. As shown in fig. 3, the hanging lug 21 is disposed at the front end of the rear fork 2, a threaded hole is formed in the hanging lug 21, and a chain guide is connected to the threaded hole, so that the chain guide can stabilize a chain of a vehicle to prevent the chain from falling.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered by the protection scope of the utility model.
