[0045] like Figure 3As shown, the support frame 110 includes a frame body 111, a slider 112, a support beam 113 and a universal wheel 114. The frame body 111 is provided with a slide groove 101, the slider 112 is slidably connected to the slide groove 101 and can move in the height direction, the support beam 113 is connected to the frame body 111 and encloses a triangle, and the triangular structure increases the stability of the support structure and reduces the load of the frame body 111. Among them, the support beam 113 can be set as a hollow round tube, a hollow square tube, etc. The universal wheel 114 is threadedly connected to the frame body 111 and rolls on the ground, wherein the wheel of the universal wheel 114 is a nylon wheel, which has high strength and impact resistance, and the nylon wheel is suitable for various environments and ground, including indoors and outdoors. It also has high corrosion resistance and chemical resistance, and has strong adaptability to canvas 001 covering in environments such as rugged ground or rainy days. The universal wheel 114 is used to push the frame body 111 to move in all directions, which improves the flexibility and convenience of the movement of the frame body 111. The support frame 110 is connected to the support rod 120 through the slider 112, thereby driving the support rod 120 to move in the height direction and facilitating driving the canvas 001 fixed to the support rod 120 to cover the car body.

[0046] Regarding the structural composition of the support rod 120, specifically:

[0047] like Figure 4 and 5 As shown, the support rod 120 includes a crossbar 121, a roller 122 and a rope connector 123. The crossbar 121 is horizontally arranged. The two ends of the crossbar 121 are detachably connected to two sliders 112 respectively. The sliding of the sliders 112 along the slide groove 101 drives the crossbar 121 to move in the height direction. The connection between the crossbar 121 and the slider 112 can be set to threaded connection, clamping or pin connection. The roller 122 is sleeved on the crossbar 121 and is rotatably connected to the crossbar 121. The rotation of the roller 122 is used to reduce the friction when the canvas 001 is unfolded. The rope connector 123 is installed on the crossbar 121 and connected to the rope 002. The connection between the rope connector 123 and the crossbar 121 can be set to threaded connection, pin connection, etc. The cross bar 121 is connected to the canvas 001 in turn through the rope connector 123 and the rope 002, wherein the rope connector 123 is configured as a hook with an opening, and the opening of the hook extends in a direction close to the second mobile frame 200, so as to fix the rope 002 and prevent the rope 002 from detaching from the rope connector 123.
