Examples

Referring to fig. 1 to 9, the present embodiment provides a shock-absorbing frame for an electric bicycle, including a front frame 1, a rear fork support 13 and a transverse shock absorber, wherein the rear fork support 13 is in an inverted V shape, the rear fork support 13 has three connecting ends, a first connecting end 18 of the rear fork support 13 is rotatably disposed on the front frame 1 through a third rotating shaft 14, and a second connecting end 19 of the rear fork support 13 has a mounting groove 2; one end of the transverse shock absorber is rotationally connected with the third connecting end 20 of the rear fork bracket 13, and the other end of the transverse shock absorber is rotationally connected with the front frame 1; the front frame 1 is provided with a hanging rear mounting rack 15, and the hanging rear mounting rack 15 is positioned above the rear fork support 13 and the transverse shock absorber.

In actual use, the front wheel is mounted on the front frame 1, the rear wheel 17 is mounted on the second connecting end 19 of the rear fork support 13, the rotating shaft of the rear wheel 17 can be mounted through the mounting groove 2, and the storage battery 16 of the electric bicycle can be mounted on the hanging type rear mounting frame 15. When the vehicle body is vibrated, the rear fork support 13 rotates along the front frame 1, the rotating position is the first connecting end 18, and at the moment, the rear fork support 13 and the front frame 1 extrude the transverse shock absorber, so that the transverse shock absorber extrudes and deforms and accumulates elastic potential energy, and vibration can be buffered and damped. Because horizontal bumper shock absorber carries out the shock attenuation through horizontal deformation, can make the personnel of riding less in the range of swing in vertical direction, improve its comfort level of riding.

Through the horizontal installation of bumper shock absorber, bypass the scheme that traditional back fork support 13 bumper shock absorber must push up, it can not influence electric bicycle's width and wheel base, and the installation advantage of bumper shock absorber like this is: when the wheel passes through the speed bump, the rear fork support 13 pushes forwards instead of upwards, and the design change can lead the hanging rear mounting rack 15 to fix the storage battery 16, and the position of the rear mounting rack is not required to be as high as the traditional position to touch the rear wheel 17. Thus, the vehicle is shorter, and the storage battery 16 is low in jumping amplitude along with the rear fork support 13 and the rear wheel 17 by arranging the hanging rear mounting rack 15, so that the reliability and the safety of the storage battery 16 are improved. The rear fork support 13 is designed along the traditional old vehicle type innovation, more accords with the aesthetic examination of people, can make the vehicle fold more narrowly, has more laminating, littleer advantage.

Through the innovation scheme of installing the horizontal bumper shock absorber of back fork support 13 for hanging rear mounting bracket 15 fixed mounting fender, need not be so high apart from rear wheel 17, back fork support 13 pushes up when rear wheel 17 pushes down, rather than upwards the roof pressure touch hanging rear mounting bracket 15, innovation structure function changes like this, just can be when the road conditions is poor, the up-and-down run-out working stroke of tire shortens, just can accord with the operating requirement, make the car shorter like this, littleer, more steady, more pleasing to the eye, more be fit for the safety design scheme who drives the specialty requirement of generation.

And through setting up horizontal bumper shock absorber, it receives the influence in wheel base and space less during the installation, can install this horizontal bumper shock absorber on multiple series's of riding motorcycle type, and the working stroke of horizontal bumper shock absorber need not be very long, can also play the effect of soft tail for shock attenuation effect is also very good when adorning short horizontal bumper shock absorber. The force of the spring is pushed forward each time the shock is absorbed, so that the vehicle is more stable and safer.

As shown in fig. 1 to 9, in some embodiments of the present invention, the third connecting end 20 of the rear fork support 13 is provided with a first rotating shaft 11, and the transverse damper is rotatably provided on the first rotating shaft 11.
