Description

Technical Field

[0001] The utility model relates to the technical field of folding vehicles, in particular to a folding vehicle. Background Art

[0002] When carrying items daily, to reduce the load, users can use a trolley for assisted carrying. Most of the existing trolleys are ordinary flatbed trolleys, which occupy a large area during storage and transportation and are inconvenient to use. In addition, there are also some retractable trolleys that use a telescopic structure to make the trolley occupy a smaller area when not in use. However, usually, the overall height of the trolley in the retracted state is much higher than that in the deployed state, so it is still not very convenient. Therefore, there is a need for a trolley that can fold to carry goods.

[0003] As disclosed in a folding vehicle with the authorization publication number CN220465525U, which relates to the technical field of vehicle folding, including a first bracket, a second bracket, and a limiting device. By setting the first rod section of the first bracket and the second rod section of the second bracket to be rotatably connected, it is convenient for the folding vehicle to switch between the deployed state and the folded state. One end of the first limiting rod is hinged to the first rod section, one end of the second limiting rod is hinged to the second rod section, the other end of the first limiting rod is hinged to the other end of the second limiting rod, and the limiting part is hinged to the first limiting rod and the second limiting rod;

[0004] Although it realizes that when the folding vehicle is in the deployed state, the included angle between the upper edges of the first limiting rod and the second limiting rod is less than 180°. Therefore, when the first rod section and the second rod section tend to approach each other, the upper edges of the first rod section and the second rod section can abut against the limiting part, thereby restricting the first rod section and the second rod section from approaching each other and improving the stability of the folding vehicle in the deployed state. However, it does not solve the problems that the existing folding vehicle is not convenient for convenient mobile walking, not convenient for transporting vertical goods or normal goods, not convenient for the folding vehicle to be folded or deployed in a convenient rotational manner, not convenient for being used as both a two-wheeled vehicle and a four-wheeled vehicle, which greatly affects the flexibility of the folding vehicle to transport goods in multiple states and the convenience of folding and carrying.
