Problems solved by technology

But, after the left and right guard plates are fixedly installed on the left and right guard frames, because the plate surface of the guard plate is greater than the area of ​​the left and right guard frames, the guard plate stretches out the guard frame, and when the motorcycle rolls over, It will cause the guard plate to touch the ground first, resulting in damage to the guard plate
Moreover, because the left and right protective frames of the bumper are stretched to both sides and are in a fixed state, the occupied space increases.
[0003] The motorcycle bumper of the above-mentioned prior art is generally made of relatively thick steel pipes, and the middle part is installed in front of the vehicle frame. Because it is an integral structure, the strength of the bumper is very high, and the connecting part between the bumper and the vehicle frame becomes the weakest part. , after a rollover accident, it often leads to damage to the connecting part, resulting in damage to the frame and high repair costs; on the other hand, once the left and right protective frames of the bumper are damaged due to collision, only the entire bumper can be replaced. Bring a greater economic burden to users

Abstract

Disclosed is a foldable bumper of a motorcycle. A fixed bumper frame, a left protection bumper frame and a right protection bumper frame of the bumper are in independent structure formed independently, the left protection bumper frame and the right protection bumper frame are rotationally mounted on the fixed bumper frame through hinge shafts, positioning blocks used for positioning rotationally are arranged on the left protection bumper frame and the right protection bumper frame respectively, each positioning block is provided with an unfolding positioning hole and a folding positioning hole, two locking devices used for locking the rotation positions of the left protection bumper frame and the right protection bumper frame are arranged on an upper transverse pipe of the fixed bumper frame, fixed seats of the locking devices are fixedly welded on the fixed bumper frame, positioning latches with bent ends are mounted vertically rotationally on the fixed seats through pins and inserted into the positioning holes on the positioning blocks and stay at normal locking state under the pressure of a reset spring. The left protection bumper frame and the right protection bumper frame of the bumper can be unfolded or folded, have protection action during running of the motorcycle or can reduce occupation space during parking, partial parts of the bumper can be replaced respectively, maintenance and replacement cost can be reduced, and the locking devices are not easy to be damaged.
