Technical Field

[0001] This application relates to the field of camper vehicle accessories technology, and in particular to a support leg structure for a camper vehicle extension box. Background Technology

[0002] Camping vans are used for picnics or outings, providing high-quality sleeping spaces, comfortable living and sleeping environments, and leisure areas for multiple people camping in the wild. Custom-designed camping vans for specific industries integrate personnel transportation and rest. This model effectively solves the contradiction between the limited passenger capacity of all-sleeper vans and the inconvenience of rest in all-seat vans, perfectly meeting the needs of military and police systems and improving the comfort of transportation and camping. When using camping vans, the issue of vehicle expansion needs to be considered.

[0003] For example, Chinese patent application number CN202321740311.2 discloses a camping vehicle with a novel extended box support structure, including a carriage. Lower guide wheels are equidistantly installed at the bottom of the carriage interior. A floor is fixedly installed on top of the lower guide wheels, and upper guide wheels are equidistantly installed on the bottom of the floor. An extension plate is installed through the upper and lower guide wheels, and slots are fixedly provided on both sides of the bottom of the extension plate. A vehicle body is fixedly installed at the bottom of the carriage, and a telescopic sleeve is installed at the bottom of the vehicle body. A telescopic rod is movably installed inside the telescopic sleeve, and an adjusting bolt is threaded onto the surface of the telescopic sleeve. A pre-embedded tooth is fixedly installed on one side of the telescopic sleeve.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist:

[0005] The support structure of the common campervan extension box is basically a separate structure from the extension box. In the actual installation, disassembly and storage process, the support structure of the extension box can easily be lost due to operator carelessness or site chaos. This is not conducive to quick deployment and storage. Moreover, the main component of the extension box support structure that contacts the ground is a pre-embedded tooth (nail-shaped structure), which has a very small contact area with the ground and is easy to damage the ground.
