Abstract

The invention relates to a frame hidden folding structure which comprises a wrench, a first pipe fitting and a second pipe fitting, wherein the first pipe fitting and the second pipe fitting are hinged to each other, notches which are communicated and spliced into a groove are formed in the same side of the first pipe fitting and the second pipe fitting, the wrench is flush with the top of the groove, and a fourth rotating shaft and a limiting rod are arranged in the notches of the first pipe fitting and the second pipe fitting respectively. The middle of the wrench is connected with a fourthrotating shaft through a connecting piece, a first clamping hook matched with the limiting rod is further arranged at one end of the wrench, a locking piece is further arranged at the other end of thewrench, a locking block is further arranged in the notch of the first pipe fitting, a locking hole is formed in the locking block, and the lower portion of the locking piece extends to form a secondclamping hook, and is matched with lock hole. The folding structure box is hidden in the frame plane, and by optimizing the structure, the folding box plane and the frame plane coincide to improve theintegration degree of frame accessories.

Description

technical field [0001] The invention relates to the technical field of folding vehicle frames, in particular to a hidden folding structure of a vehicle frame. Background technique [0002] The whole world is advocating energy conservation and emission reduction, and my country is a well-deserved bicycle power. Folding bicycles have become a very important category of bicycles because of their easy portability and small footprint, and they are becoming more and more popular. Most of the existing folding bicycles will have a folding joint in the middle of the frame. One of the structures is a horizontal folding bicycle. The hinge axis of the folding joint is arranged vertically. During the folding process, the front part of the frame and the rear part of the frame rotate in the horizontal plane. Until close together, for example Chinese patent CN201220473203.9 discloses "folding bicycle frame". The folding structure of this kind of bicycle frame generally protrudes from the ...
