The main box body is fitted onto the box body fixing plate, and the upper end of the box body fixing plate is mounted on a vehicle frame fixing plate. The upper end of the main box body is detachably connected to the vehicle frame fixing plate via a detachable buckle. A partition is installed inside the main box body to divide its interior into two compartments, an outer compartment door is hinged to one end of the outer compartment, and an inner compartment door is hinged to one end of the inner compartment.

[0005] Optionally, a fan is installed on one side of the main housing, and the outer hatch is flush with the outer compartment port of the main housing when closed, with the hinge of the outer compartment and the outer hatch close to the fan side.

[0006] Optionally, the inner cabin door is flush with the inner compartment port of the main body after closing, the hinge point between the inner compartment and the inner cabin door is away from the fan, and an intelligent driving module is installed inside the inner compartment.

[0007] Furthermore, by releasing the detachable buckle, the main body is freed from the constraint of the frame fixing plate, and downward force is applied to make the main body rotate around the body fixing plate via the rotating auxiliary.

[0008] Furthermore, the side of the box fixing plate is provided with a rotation limiting block, the impact surface of which cooperates with the limiting groove provided at the bottom of the main box to limit the rotation angle of the main box to 155±5°.

[0009] Optionally, the outer hatch is provided with a waterproof connector panel, which is recessed into the interior of the housing.

[0010] Optionally, the rotary pair includes an inner rotating shaft and an outer rotating sleeve connected to the outside of the inner rotating shaft, with a clearance fit tolerance of H7 / g6.
