A groove (22) is arranged on the front frame (1) , the rear frame (2) is hinged with the groove (22) in a sliding way, and the front end of the rear frame (2) is hinged with the two side walls of the front part of the groove (22); the rear end of the front frame (1) and the rear frame (2) are provided with the locking device which can lock or release the rear end of the frond frame (1) as well as the relative position of the rear frame (2) corresponding to the end part of the front frame. The folding device has the advantages of simple structure, fast speed in folding and unfolding process, easy operation, and good applicability among folding vehicles.

Description

technical field [0001] The invention relates to a folding vehicle device used for the frame of folding vehicles such as folding bicycles, folding mopeds or folding scooter. Background technique [0002] With the sharp rise of global energy prices and the aggravation of environmental pollution, people pay more and more attention to energy-saving, environmentally friendly and fitness vehicles.

Problems solved by technology

While it brings convenience to people's travel, it also has a little regret, because the folding devices of the frame of the existing folding bicycle generally have the shortcomings of inconvenient folding operation and slow folding speed.

For example, the folding mechanism shown in the utility model whose authorization announcement number is CN 2712782Y and authorization announcement number is CN 2686994Y needs to slide the hinge shaft when folding and unfolding, and the hinge shaft has a quick release locking mechanism. The structure is slightly complicated, and the operation steps are increased, which makes the folding and unfolding of the folding device slower (it takes about 3 to 5 seconds), and the operation is not very convenient, especially when the above folding device is used for folding bicycles, folding mopeds or folding bicycles. The versatility is not strong in folding vehicles such as scooters
