A push plate 28 is connected to the lower end of the side wall of the movable slide 22. The push plate 28 is arranged under the wing plate 7, and the push plate 28 is fixed to one end of the cleaning component 8.

[0042] In this embodiment, the L-shaped plate 23 can protect the tarpaulin unfolding and retracting assembly 5 above the storage slot 4. When the L-shaped plate 23 rotates around the slide bar 26 to the other side of the movable slide plate 22, and then drives the slide bar 26 to move along the through slot 25 to the lower end of the connecting slot 24, the lower wall of the L-shaped plate 23 contacts the wing plate 7. At this time, the wing plate 7 supports the L-shaped plate 23. The L-shaped plate 23 and the movable slide plate 22 together form a bench shape. When the movable slide plate 22 is pushed to slide along the side slide slot 10, the movable slide plate 22 drives the push plate 28 to squeeze the cleaning assembly 8, thereby driving the cleaning assembly 8 to clean the residue between the car floor plate 6 and the side compartment plate 9.

[0043] like Fig.10 , Fig.11 and Fig.15As shown, a first wire hole 29 and a second wire hole 30 are provided in parallel on the wing plate 7. The first wire hole 29 is provided close to the inner wall of the side compartment plate 9. The push plate 28 movably passes through the first wire hole 29 and is provided below the wing plate 7.

[0046] In this embodiment, when the movable slide plate 22 is pushed to slide along the side slide groove 10, the movable slide plate 22 drives the push plate 28 to move along the first linear hole 29 and squeeze the telescopic airbag 32. After being squeezed, the volume of the telescopic airbag 32 is reduced and the internal gas enters the first air outlet pipe 33. A part of the gas in the first air outlet pipe 33 is sprayed toward the second linear hole 30 to clean the residue between the car floor 6 and the side compartment plate 9, and the other part of the gas is sprayed toward the first linear hole 29 through the second air outlet pipe 34 to clean the residue in the first linear hole 29. When the movable slide plate 22 drives the push plate 28 to approach the pedal frame 2, the telescopic airbag 32 is stretched to form a negative pressure inside, and the air flows into the telescopic airbag 32 through the one-way air valve 35.

[0047] like Figure 5 and Fig.15 As shown, a protective plate 36 is fixedly provided on the lower wall of the wing plate 7. The protective plate 36 is arranged outside the telescopic airbag 32, and the protective plate 36 is arranged in an L shape.

[0048] In this embodiment, the protection plate 36 can protect the side wall and the lower wall of the telescopic airbag 32 to prevent the telescopic airbag 32 from being damaged by sharp objects.

[0049] like Fig.12 As shown, the lower wall of the movable slide plate 22 is provided with bristles 37, and the bristles 37 are arranged in close contact with the upper wall of the carriage bottom plate 6. The other end of the L-shaped plate 23 is provided with bristles 38, and the bristles 38 and the bristles 37 are arranged in the same length.

[0050] In this embodiment, when the L-shaped plate 23 rotates around the slide rod 26 to the other side of the movable slide plate 22, and then drives the slide rod 26 to move along the through groove 25 to the lower end of the connecting groove 24, the bristles 2 38 on the L-shaped plate 23 are connected with the vehicle floor 6, and when the movable slide plate 22 is pushed to slide along the side slide groove 10, the telescopic airbag 32 blows out the residue in the gap between the vehicle floor 6 and the side vehicle panel 9 through the first air outlet pipe 33 and the second air outlet pipe 34, and at the same time, the bristles 1 37 and the bristles 2 38 clean the surface of the vehicle floor 6, thereby keeping the vehicle clean.

[0051] like Figure 3 and Figure 5 As shown, a thickened beam 39 is provided on the pedal frame 2 , one end of the thickened beam 39 is fixed on the upper wall of the pedal frame 2 , the other end of the thickened beam 39 is fixed on the rear shelf 3 , and the storage groove 4 is provided above the thickened beam 39 .

[0052] In this embodiment, the thickened beam 39 increases the stability of the pedal frame 2 and the rear rack 3 , improves the overall load-bearing strength of the frame, and provides a stable support for the storage slot 4 and the tarpaulin retractable and deployable assembly 5 .

[0054] The main functions of the suspension device 40 include transmitting force and torque, providing buffering, maintaining good contact between the wheel and the ground, ensuring that the wheel moves within a fixed angle, supporting the weight of the wheel, and improving driving smoothness.

[0055] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a front wheel hub 42 is disposed at the lower end of the front frame 1 , and the front wheel hub 42 and the rear wheel hub 41 are disposed at the same level.

[0056] When used for freight, the compartment floor 6 and the side compartment plates 9 form an open compartment space, and the user can put the goods into the compartment space. When unloading, the movable slide plate 22 can be dragged to slide along the side slide groove 10. The movable slide plate 22 drives the push plate 28 to squeeze the telescopic airbag 32. After being squeezed, the volume of the telescopic airbag 32 is reduced and the internal gas enters the first air outlet pipe 33. A part of the gas in the first air outlet pipe 33 is sprayed to the second line hole 30 to clean the residue between the compartment floor 6 and the side compartment plate 9, and the other part of the gas is sprayed to the first line hole 29 through the second air outlet pipe 34 to clean the residue in the first line hole 29. At the same time, the bristles 1 37 and the bristles 2 38 clean the surface of the compartment floor 6, so as to keep the compartment clean. When the movable slide plate 22 drives the push plate 28 to approach the pedal frame 2, the telescopic airbag 32 is stretched to form a negative pressure inside, and the air is refilled into the telescopic airbag 32 by the one-way air valve 35.

[0057] When used for passenger transportation, the L-shaped plate 23 is rotated around the slide bar 26 to the other side of the movable slide plate 22, and then the slide bar 26 is driven to move along the through groove 25 to the lower end of the connecting groove 24, and the lower wall of the L-shaped plate 23 contacts the wing plate 7. At this time, the wing plate 7 supports the L-shaped plate 23, and the L-shaped plate 23 and the movable slide plate 22 together form a bench shape. Then, the movable slide plate 22 is pushed to move along the side slide groove 10 to adjust the movable adjustment component 11 to a suitable position for the user to sit down. After the movable ends of the two groups of first telescopic rods 12 drive the X-shaped member 14 to rise to a suitable height, the second telescopic rod 13 drives the lower end of the first X-shaped member 14 to rise along the limiting groove 18 and move close to the upper end of the X-shaped member 14, thereby adjusting multiple X-shaped members 14 is driven, at this time, the distance between the upper end 1 and the upper end 2 of the X-shaped member 14 increases, and the distance between the lower end 1 and the lower end 2 of the X-shaped member 14 increases, thereby driving the V-shaped member 15 to extend and move away from the storage groove 4, driving the distance between the connecting rods 20 to increase, and the connecting rods 20 unfold the ceiling patchwork 17 through the fixing belt 21 to shade the car. When the second telescopic rod 13 drives the lower end 1 of the first X-shaped member 14 to rise to the uppermost end of the X-limiting groove 18, the V-shaped member 15 extends to the farthest distance. At this time, the third telescopic rod 16 is stretched and inserted into the socket 19 on the side compartment plate 9 for fixing. The third telescopic rod 16 supports the upper X-shaped member 14 and the V-shaped member 15.
