[0013] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, obvious and easy to understand, the specific embodiments of the utility model are described in detail below. In the following description, a large number of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed base body implementation.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0015] The specific embodiments of the utility model are further described in detail below in combination with the drawings.

[0016] By Figs. 1 to 4 It is given, including vertical pipe 1, the left end of vertical pipe 1 is equipped with front support pipe 2, vertical pipe 1 front and rear ends are equipped with guard plate 3 respectively, guard plate 3 is rotatably connected with shock absorber 4 inside, the upper end of shock absorber 4 is rotatably connected with triangular connecting plate 5, the lower end of connecting plate 5 is rotatably connected with guard plate 3, the right end of connecting plate 5 is hingedly connected with rear upper fork 6, the lower side in guard plate 3 is rotatably connected with rear lower fork 8 through rotating pipe 7, rear upper fork 6 is fixedly connected with rear lower fork 8 through rear lifting lug 9.

[0017] In order to facilitate use, the vertical pipe 1 is provided with the seat pipe 10 in the axial direction.

[0018] In order to facilitate observation of the condition of shock absorber 4, the observation groove 11 is formed in the guard plate 3.

[0019] In order to facilitate the increase of structural strength, the reinforcing column 12 is arranged on the rear lower fork 8.

[0020] In order to facilitate the placement of the battery, the placing groove 13 is formed in the front support pipe 2.

[0021] The utility model discloses when using, when the rider is riding, when encountering uneven and bumpy road section, the rear wheel is impacted, the wheel drives rear hanger 9 to swing upwards, rear hanger 9 drives rear upper fork 6 and rear lower fork 8 to swing upwards in turn, rear upper fork 6 drives the right end of connecting plate 5 to swing upwards in turn, the right end of connecting plate 5 swings downwards and drives the left end to swing downwards, and the left end further extrudes shock absorber 4, so that shock absorber 4 swings in the protection board 3, thereby playing the role of shock absorption, when the rear wheel passes uneven road surface, due to the restoring force of shock absorber 4, the right end of connecting plate 5 swings downwards, and rear upper fork 6 and rear lower fork 8 are further swung downwards, and finally the rear wheel swings downwards to the initial position;
