[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] This utility model discloses an integrated automatic roll-up system for truck tarpaulins.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the integrated automatic tarpaulin rolling system for trucks includes a main frame 1 and a truck bed 22. Matching frames 21 are fixedly connected at equal intervals inside the truck bed 22. The main frame 1 is fixedly connected inside the truck bed 22 and outside the matching frames 21. Teeth 2 following the shape of the main frame 1 are formed on each of the main frame 1. A dual-shaft motor 3 is fixedly connected below one of the matching frames 21. Rotating rods 4 are fixedly connected to the output ends of the dual-shaft motors 3. Retaining rings 5 ​​are fixedly connected to both ends of the rotating rods 4. Connecting shafts 6 are fixedly connected to each rotating rod 4. First threaded holes 60 are formed inside each connecting shaft 6. 1. Gears 7 are connected to the outer side of the connecting shaft 6 via a flat key structure. The gears 7 are meshed with the corresponding teeth 2. Grooves 11 are provided on the side of the two main frames 1 that are far apart. Fixing blocks 12 are slidably connected inside the grooves 11. Abutting rings 13 are rotatably connected to the outer side of the fixing blocks 12. Connecting blocks 10 are fixedly connected to the end of the fixing blocks 12 that is far away from the corresponding main frame 1. Bearings 8 are connected inside the connecting blocks 10. The inner ring side of the bearing 8 abuts against the end face of the connecting shaft 6. Bolts 9 are provided inside the bearing 8. Bolts 9 are threadedly connected to the first threaded hole 601.

[0024] In this embodiment, the main frame 1 and the mating frame 21 are fixed to the truck bed 22 by welding or threaded connection. The dual-shaft motor 3 is installed on the mating frame 21 located in the middle, and its bottom can also be connected to the truck bed 22. The rotation of the dual-shaft motor 3 can drive the rotating rod 4 to rotate. When the rotating rod 4 rotates, it can drive the gear 7 to rotate, so that the gear 7 can mesh with the teeth 2 to realize power transmission.

[0025] A gear 7 is connected to the connecting shaft 6, and the gear 7 is limited by the cooperation of a flat key and a keyway. The advantage of this setting is that the gear 7 can be replaced later, thereby extending the service life of the device. When the gear 7 rotates, the inner ring of the bearing 8 that abuts against the gear 7 will also rotate, thereby driving the bolt 9 to rotate. The advantage of this setting is that although the bearing 8 is installed on the connecting block 10, its movement will not interfere with the connecting block 10. At the same time, the connecting block 10 can be moved through the bearing 8.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, the groove 11 is configured as a "U" shaped structure, the connecting block 10 is provided with a second threaded hole 14, the second threaded hole 14 is internally threaded with a lead screw 15, the lead screw 15 is provided with a rotating ring 16, the rotating ring 16 is fixedly connected with a connecting rod 1501, the connecting rod 1501 is provided with a slot 1502, the slot 1502 is rotatably connected with a roller 17, the roller 17 abuts against the main frame 1 and rolls on its outside.

[0027] In this embodiment: When gear 7 rotates, it moves due to meshing with teeth 2. Simultaneously, the connecting block 10 moves along with it due to bolt 9 and bearing 8. At this time, fixing block 12 and contact ring 13 also move within groove 11. The purpose of groove 11 being U-shaped is to prevent fixing block 12 and contact ring 13 from disengaging from their grooves, thereby limiting the movement of connecting block 10. As connecting block 10 moves, lead screw 15 also moves accordingly. Lead screw 15 can move back and forth by rotating, ensuring that roller 17 is in tight contact with one side of main frame 1. In this way, the contact ring 13 and fixing block 12 form a double limit, ensuring that connecting block 10 can stably follow gear 7.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in a preferred embodiment, pull rings 18 are equidistantly connected to the rotating rod 4, and a tarpaulin box 19 is fixedly connected inside the truck bed 22. Tarpaulin is wound inside the tarpaulin box 19 by a torsion spring, and the tarpaulin is connected to the pull rings 18.

[0029] In this embodiment: During the movement of the rotating rod 4, the tarpaulin is raised by the pull ring 18. The tarpaulin is connected to the inside of the tarpaulin box 19 by a torsion spring structure, which ensures that when the tarpaulin returns, it can be rolled up inside the tarpaulin box 19. This allows for operation without manual assistance and facilitates repeated use in the future.

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, the main frame 1 and the mating frame 21 are configured as an open rectangular structure, with a magnet 20 fixedly connected below the crossbar, and a magnetic strip for use with the magnet 20 is provided on the tarpaulin.

[0031] In this embodiment, after the tarpaulin moves to the range of the magnet 20, the magnetic strip on one side of it will be attracted to the magnet 20, ensuring that a part of the tarpaulin is attracted to the top of the mounting frame 21, thereby covering the objects inside the truck bed 22.

[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, the dual-axis motor 3 is electrically connected to the vehicle control device.

[0033] In this embodiment, the operator uses a manual remote control to start the dual-axis motor 3 to make the equipment run, which is convenient for control.

[0034] Working principle: When the tarpaulin is needed, the staff controls the rotating rod 4 to rotate through the remote control device, which drives the gear 7 to mesh and rotate in the teeth 2. At the same time, the rotation of the gear 7 will also cause the inner ring of the bearing 8 to rotate, thereby driving the bolt 9 and the connecting block 10 to rotate.

[0035] In addition, the fixing block 12 and the abutting ring 13 move within the groove 11 without disengaging from the groove and limiting the connection block 10. Meanwhile, as the connection block 10 moves, the lead screw 15 on its structure moves forward by rotating, ensuring that the roller 17 is in tight contact with one side of the main frame 1, so that the connection block 10 can stably follow the gear 7 to move.

[0036] When the gear 7 moves, the equidistant pull rings 18 on the rotating rod 4 will move the tarpaulin inside the tarpaulin box 19, thereby covering the goods. This can greatly reduce manpower and improve work efficiency.

[0037] It should be noted that this application requires the use of a controller or other components with control effects in actual use. Since these are known technologies and not within the scope of protection of this application, they are not shown in this application.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
