Description

Technical Field

[0001] The utility model relates to the technical field of trailer vehicles, and particularly relates to a multi-functional trailer device for an all-terrain electric scooter. Background Art

[0002] An all-terrain vehicle refers to a vehicle that can travel on any terrain and can move freely on terrains where ordinary vehicles are difficult to maneuver. It is also called an ATV (All-Terrain Vehicle); and its structure is very similar to that of a motorcycle, so many components are common with motorcycles, and it is also called a four-wheel motorcycle. This type of vehicle has multiple uses and is not restricted by road conditions, so it is widely welcomed.

[0003] However, this vehicle has a drawback. Although it has strong terrain adaptability, it has almost no cargo-carrying capacity, so its usage scenarios are still limited; regarding the problem of its cargo-carrying capacity, the current solution is to use an external trailer, connecting the trailer carrying goods to the all-terrain vehicle, which not only solves the cargo-carrying capacity problem but also does not affect its off-road performance.

[0004] Regarding the method of using an external trailer for an all-terrain vehicle, the applicant found in actual research and development that when separating the external trailer from the all-terrain vehicle, if there is a need to adjust the position, it is necessary to re-hitch the trailer to the all-terrain vehicle again, which is rather cumbersome; and if the trailer is transferred alone, it will be laborious to transfer due to its own weight and it is also difficult in complex terrains. Regarding this problem, a new external trailer device is needed. Content of the Utility Model
