[0028] In order to solve the problems existing in the prior art, an embodiment of the present application provides a vehicle tarpaulin covering device, wherein the vehicle comprises a front and a vehicle box 4 with an open top, such as Figure 1 As shown, the vehicle tarpaulin covering device includes a U-shaped frame, the material of the U-shaped frame is stainless steel; the U-shaped frame includes a cross bar 1 extending along a first direction and located on the top of the vehicle box 4, the first direction is Figure 1 In the middle X direction, two vertical rods 2 are formed by the two ends of the crossbar 1 extending downward. The ends of the two vertical rods 2, away from the crossbar 1, are rotatably connected to the two opposite first outer side walls 41 of the vehicle box 4. Driven by the vertical rods 2, the crossbar 1 can move from the side of the vehicle box 4 away from the front to the side close to the front. A reel 5 is mounted on the top of the second outer side wall 42 of the vehicle box 4 close to the front. The reel 5 extends along the first direction, with one side of the tarpaulin 6 connected to the crossbar 1 of the U-shaped frame and the other side connected to the reel 5. The reel 5 is configured to retract the unfolded tarpaulin 6 located at the top of the vehicle box 4. Here, the reel 5 can rotate clockwise when retracting the tarpaulin 6 and counterclockwise when unfolding the tarpaulin 6.
[0029] In the above embodiment of the present application, the two side portions of the tarpaulin 6 are respectively connected to the cross bar 1 and the reel 5. When the tarpaulin 6 needs to be converted from the unfolded state to the folded state, that is, when the tarpaulin 6 covering the entire top of the car box 4 needs to be retracted, it is only necessary to rotate the reel 5 clockwise. When the reel 5 rotates, the tarpaulin 6 is retracted by the reel 5. Driven by the tarpaulin 6, the cross bar 1 moves from the side of the top of the car box 4 away from the front of the car to the side close to the front of the car. At the same time, the vertical bar 2 rotates relative to the first outer side wall 41 of the car box 4 until the cross bar 1 moves to the edge of the side of the car box 4 close to the front of the car. The cross bar 1 stops moving under the obstruction of the top of the car box 4. At this time, the top of the car box 4 The tarpaulin 6 is rolled up by the reel 5; when the tarpaulin 6 needs to be transformed from the folded state to the unfolded state, that is, when the tarpaulin 6 rolled up by the reel 5 needs to be unfolded and covers the entire top of the vehicle box 4, the reel 5 rotates counterclockwise, and at the same time, the cross bar 1 moves from the side of the vehicle box 4 close to the top front of the vehicle to the side away from the front of the vehicle. When the reel 5 rotates, the tarpaulin 6 is unfolded, and driven by the cross bar 1, the tarpaulin 6 gradually unfolds from the side close to the front of the vehicle box 4 to the side away from the front of the vehicle box 4, until the cross bar 1 moves to the side of the vehicle box 4 away from the front of the vehicle box, and the cross bar 1 stops moving under the obstruction of the top of the vehicle box 4. At this time, the top of the vehicle box 4 is completely covered with the tarpaulin 6. The vehicle tarpaulin and covering device provided by the present application can realize the transformation of the tarpaulin 6 from the folded state to the unfolded state, and from the unfolded state to the folded state, only under the action of the U-shaped frame and the reel 5. It is simple and convenient, does not require other complex structures, and has low production cost.
[0030] In a specific embodiment, the end of the vertical bar 2 of the U-shaped frame that is away from the horizontal bar 1 is connected to the middle position of the bottom of the first outer side wall 41 of the vehicle box 4. In this way, the movement trajectory of the horizontal bar 1 is an arc. When the vertical bar 2 is completely vertical, the horizontal bar 1 is relatively close to the top opening of the vehicle box 4. The sheet 6 swings less during the transition from the unfolded state to the folded state, or vice versa, and is more stable. During the movement of the horizontal bar 1, the sheet 6 will not be unstable due to the sheet 6 being blown by the wind during the transition from the unfolded state to the folded state, or vice versa, due to the horizontal bar 1 being far away from the top of the vehicle box 4.
[0031] In one specific example, the vertical rod 2 extends from one end of the horizontal rod 1 toward the vehicle box 4 and is formed with a rotating portion 3, which is arranged perpendicular to the vertical rod 2. A mounting hole is provided in the middle of the bottom of the first outer wall 41 of the vehicle box 4, and the rotating portion 3 is inserted into the mounting hole. This allows the vertical rod 2 and the vehicle box 4 to be connected as a whole, and the vertical rod 2 can rotate relative to the vehicle box 4, thereby moving the horizontal rod 1 and deploying or retracting the sheet 6.
[0032] In a specific embodiment, if Figure 1 As shown, the device further includes an elastic member 7, which may be a tension spring; one end of the elastic member 7 is rotatably connected to the connection between the first outer side wall 41 of the vehicle box 4 and the vertical rod 2, away from the vehicle front, and the other end is rotatably connected to the vertical rod 2. As the sheet 6 transitions from an unfolded state to a folded state, that is, as the crossbar 1 moves from an edge away from the vehicle front to an edge closer to the vehicle front, the elastic force of the elastic member 7 gradually increases. When the crossbar 1 moves to the edge closer to the vehicle front, the elastic force of the elastic member 7 reaches its maximum. Since the sheet 6 is now connected between the crossbar 1 and the reel 5, after the reel 5 stops rotating, the crossbar 1 will not move under the action of the elastic force of the sheet 6. When the tarpaulin 6 needs to be transformed from a folded state to an unfolded state, the reel 5 rotates counterclockwise, and the vertical rod 2 rotates toward the direction of the car box 4 away from the front of the vehicle under the action of the elastic force of the elastic member 7, that is, the cross bar 1 moves toward the side edge of the car box 4 away from the front of the vehicle. Since the elastic force of the elastic member 7 gradually decreases, when it decreases to a certain extent, the staff needs to manually drive the vertical rod 2 to rotate until the cross bar 1 rotates to the side edge of the car box 4 away from the front of the vehicle. At this time, the tarpaulin 6 is in a fully unfolded state. It should be noted that the entire process of the vertical rod 2 rotating toward the direction of the car box 4 away from the front of the vehicle under the action of the elastic force of the elastic member 7 is monitored on site by staff. When the vertical rod 2 rotates to a certain angle, the staff will drive the vertical rod 2, so the vertical rod 2 will not stop rotating before the cross bar 1 reaches the side edge of the car box 4 away from the front of the vehicle.
[0033] In addition, the provision of the elastic member 7 can also improve the rotational stability of the vertical rod 2 when the vertical rod 2 rotates toward the front of the vehicle, that is, when the cross bar 1 moves toward the edge of the vehicle box 4 close to the front of the vehicle.
[0034] In one embodiment, the device further includes a driving member 9 fixed to the second outer side wall 42 of the vehicle box 4 and located below the reel 5. The driving member 9 is configured to rotate the reel 5. When the sheet 6 needs to be transformed from an unfolded state to a folded state, or vice versa, the driving member 9 is activated to rotate the reel 5. Here, the driving member 9 can drive the reel 5 to rotate clockwise or counterclockwise. The appropriate rotation mode is selected according to whether the sheet 6 is unfolded or folded to achieve rotation of the reel 5.
[0035] In one embodiment, both ends of the crossbar 1 include protruding rods 11, each having a pointed top. When the sheet 6 is fixed to the crossbar 1, the protruding rods 11 can pass through the two ends of the sheet 6 connected to the crossbar 1. In this way, the two ends of the sheet 6 connected to the crossbar 1 can be stably fixed to the crossbar 1 and will not accumulate toward the middle of the crossbar 1, which is conducive to the deployment or folding of the sheet 6. Of course, connecting rings can also be installed at the two ends of the sheet connected to one side of the crossbar 1, and the connecting rings can be mounted on the protruding rods 11, which can also prevent the sheet 6 from accumulating toward the middle of the crossbar 1.
[0036] In a specific embodiment, fixing plates 8 are provided at both ends of the top of the second outer side wall 42 of the vehicle box 4; the two ends of the reel 5 are rotatably connected to the corresponding fixing plates 8. The design of the fixing plates 8 can fix the reel 5 to the second outer side wall 42 of the vehicle box 4, providing support for the reel 5.
[0037] In one embodiment, both sides of the sheet 6 include at least one anti-rolling strip 61, preferably two, extending from one end of the sheet 6 to the other end. Since the sheet 6 is relatively flexible, the anti-rolling strips 61 prevent the opposite sides of the sheet 6 from curling during and after unfolding, and also serve to secure the sheet.
[0038] The vehicle tarpaulin and covering device provided in the present application can cover the top opening of the vehicle box 4 with the tarpaulin 6 through the cooperation of the reel 5, the U-shaped frame, the elastic member 7, the driving member 9 and the tarpaulin 6, and can also retract the tarpaulin 6 covering the top opening of the vehicle box 4. It has a simple structure, low production cost, easy operation, time and labor saving, and is easy to replace and repair after a fault occurs.
[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
