Problems solved by technology

[0002] With the change of modern people's travel habits, folding vehicles are becoming more and more popular due to their advantages of small size, light weight, and portability. Folding vehicles have many functions, many accessories, and complex design. The folding effect often takes cumbersome construction and multiple operation steps
In the existing technology, the folding mechanism and the locking and unlocking mechanism belong to different structural modules. The folding mechanism is designed first, and then the locking mechanism is added on the basis of the folding mechanism, which violates the original design intention of the folding product and makes the finished product bloated.
In addition, people also have high requirements for the convenience of folding folding vehicles. The multiple operation steps are too cumbersome, which will make the operator lose patience and reduce the fit between the product and the market; High locking firmness for safety
