Description

Technical Field

[0001] The utility model relates to the technical field of folding parts, and more specifically, to a folder. Background Art

[0002] For folding vehicles (such as folding bicycles, folding electric vehicles and folding scooters, etc.), in order to facilitate the folding of the uprights, a corresponding folder structure is generally installed between the uprights and the frame. When in use, the folder is in a locked state; when not in use, the folder is in a folded state.

[0003] The lock structure used in the existing folder has poor stability before and after folding, and is prone to shaking during use. Therefore, we make improvements to this and propose a folder.

[0004] For example, a Chinese patent (publication number CN214451580U) discloses a folding device that is easy to operate and a scooter with the folding device. Its specification discloses that the folding structure of the scooter is generally only convenient for folding the scooter, and cannot realize the positioning of the front straight rod of the scooter after folding. It is also necessary to set a locking structure on the scooter body to realize the fixation of the folding structure of the scooter. The locking structure set on the scooter body not only affects the aesthetics of the scooter, but also affects the safety of the scooter when in use. In addition, these locking structures have poor stability after the scooter is folded and fixed, and the front straight rod of the scooter is easy to shake. The above patents can prove the defects of the existing technology. Utility Model Content
