When the cover 20 is opened, the cover fixing member is separated from the vehicle body mounting member, the three restraint points are simultaneously released, and the cover 20 can be detached from the vehicle body 10 at one time.

Compared with the traditional rotary hinge structure, the vehicle body mounting component and the machine cover fixing component are only arranged on the vehicle body 10 and the machine cover 20 and can be opened when needed, the traditional hinge mechanism is not needed for fixing, and the traditional cable opening structure is not needed for unlocking. This application has adopted hole axle bolt fit formula structure to replace traditional rotatory hinge structure, and overall structure is simple, and convenient to use saves the cost.

The first fixing member 50 fixes the lid 20 at different positions of the body 10 in both the closed and open states by being assembled with the first mounting seat 30 and the lid support 70, respectively. The set of the set cover support 70 can provide a temporary support for the set cover 20 after being separated from the body 10 without providing an additional space for placing the set cover 20. Since the cover support 70 is located at the rear end of the vehicle body 10 and adjacent to the first mounting seat 30, the cover 20 can be directly placed on the cover support 70 after being removed, and the operation is simple. The cover 20 is less likely to collide with and scrape on the vehicle body 10, and the cover 20 can be protected more effectively.

The above description is only for the purpose of illustrating the preferred embodiments of the present application and is not to be construed as limiting the present application in any way, and any modifications, equivalents, improvements and the like made within the scope of the present application are intended to be included therein.
