Description

Technical Field

[0001] The invention relates to the technical field of vehicle accessories, in particular to a vehicle tarpaulin device that can be quickly installed. Background Art

[0002] As an important covering material, tarpaulin is widely used in transportation, warehousing, construction and other fields. It is mainly used to protect goods and equipment from weather, dust and other external factors. In the transportation industry, the use of tarpaulin is particularly common, especially on freight trucks and trailers. At present, most of the tarpaulin devices on the market are simple in design and single in function. They only cover and protect the goods by spreading the tarpaulin on the roof and then using ropes to tie the reserved holes on the tarpaulin to the trailer. However, this method is not only cumbersome to install, but also requires workers to climb up and down to check whether the tarpaulin at each position is spread flat and bolted firmly. It is not only time-consuming and labor-intensive, but also has only a rough use. The method is to climb up the carriage manually, tie the tarpaulin around the carriage with ropes after the manual laying is completed, and fully cover the cargo on the trailer. However, when unloading, the reverse disassembly operation is required, which is also time-consuming and laborious. Once the automated tarpaulin rolling equipment is used, the design of the installation position of these equipment and the maintenance work need to be considered, which invisibly increases the workload. In this regard, the existing tarpaulin devices do not have a tarpaulin device that can realize multiple combined use modes under the premise of ensuring convenient installation and storage. It is not only inconvenient to install, but also lacks the required functional flexibility and convenience, and cannot be adjusted and used according to the needs of different weather and environments. These problems not only affect the use effect of the tarpaulin, but also greatly reduce the efficiency and safety of cargo transportation. Summary of the invention

[0014] The present invention provides a vehicle-mounted tarpaulin device that can be quickly installed, which has the following beneficial effects:

[0015] 1. The quickly installable vehicle-mounted tarpaulin device provides users with a variety of combined use modes through the installation and use of the tarpaulin device in different directions of the vehicle compartment and the combination design of the movable detachable tarpaulin and the double-layer tarpaulin. It has a convenient unloading mode, and the movable detachable tarpaulin can also be removed and used in a semi-shielded mode to adapt to the needs of different weather and environments, thereby improving the flexibility and convenience of the tarpaulin device.

[0016] Second, the vehicle-mounted tarpaulin device that can be quickly installed can be folded upward around the third cross bar when the tarpaulin device is not in use by manually removing the bolt structure on the corner seat and removing the assembly support of the limit plate on both ends of each rod-shaped structure, so that the tarpaulin device can be folded and stored as a whole on the frame on the top of the car. In particular, it can be folded and stored. When the car itself has a door frame-shaped bracket, the tarpaulin device can be tied to the top of the car frame with a rope, so that the interior space of the car can be exposed and the ventilation measure for the interior space of the car can be achieved; and when the car itself does not have a door frame-shaped bracket, the tarpaulin device can be more conveniently folded and stored inside the car for storage and cleaning.

[0017] 3. The vehicle-mounted tarpaulin device that can be quickly installed can utilize a plurality of triangular stabilizing structures formed by the first cross bar, the second cross bar, the third cross bar, the first diagonal support bar and the second diagonal support bar that constitute the frame assembly to enhance the stable supporting performance of the tarpaulin device.

While ensuring the stable supporting performance of the frame assembly for the double-layer tarpaulin, the double-layer tarpaulin is given its own deformability, and will not be rigidly pulled or collided with strong winds or foreign objects, which can enhance the tear resistance of the tarpaulin device when encountering strong winds or foreign objects.

[0019] 5. The quickly installed vehicle-mounted tarpaulin device has multiple reinforcement designs, such as the corresponding structural design of reinforcement tubes, thickened rings, and diagonal braces, which ensures the stability of the tarpaulin in various weather conditions, reduces damage caused by wind or other external forces, and reflects the stability and safety of the structure.

[0043] The surface of the third cross bar 43 and the parts near the two ends are symmetrically connected with hoop sleeves 431, and the surface of the hoop sleeve 431 is connected with an insertion cap 432. The diagonal support rod 1 44 and the diagonal support rod 2 48 are both provided with curved surface notches at one end near the hoop sleeve 431, and the diagonal support rod 1 44 is inserted into the hoop sleeve 431 through the insertion cap 432, and the diagonal support rod 1 44 is installed in a fit with the hoop sleeve 431 through the curved surface notch.

[0044] Annular grooves 411 are provided on the surface of the first cross bar 41 and at both ends close to the limiting plate 5, and hoop rings 412 are embedded and installed inside the annular grooves 411, and anti-loosening washers 413 are installed on the surface of the first cross bar 41, and inner screw rods 414 are threadedly connected to the middle parts of both ends of the first cross bar 41, and an external sleeve 415 is fixedly connected to the surface of the inner screw rod 414, and the external sleeve 415 is threadedly installed on the surface of the first cross bar 41, and the anti-loosening washers 413 are clamped and installed between the external sleeve 415 and the hoop ring 412 through the inner screw rod 414, and the limiting plate 5 is assembled with the double-layer tarpaulin 1 through the hoop ring 412, the anti-loosening washers 413, the inner screw rod 414 and the external sleeve 415, and the ends of the first cross bar 41 and the second cross bar 42, the ends of the second cross bar 42 and the third cross bar 43, and the ends of the third cross bar 43 and the cross beam 6 are all installed with the limiting plate 5 through the inner screw rod 414 and the external sleeve 415.

[0045] Before use, the first cross bar 41, the second cross bar 42, the third cross bar 43 and the cross beam 6 are respectively inserted into the sleeve portion 11 on the inner side of the double-layer tarpaulin 1, and when the cross beam 6 is longitudinally inserted into the sleeve portion 11, since the open hoop 71 itself is embedded and installed at the two ends of the sleeve portion 11, the cross beam 6 is additionally positioned and clamped in the double-layer tarpaulin 1 by the open hoop 71 while being inserted into the sleeve portion 11; then the double tube 7 is inserted into the double-layer tarpaulin 1 from the top of the double-layer tarpaulin 1, and the double tube 7 is passed through the bottom of the long prism 8, and then a group of ball head connecting rods 73 connected to the left end of the double tube 7 are clamped into the ball head clamping groove 711 from the embedding groove 712. During this period, the ball head connecting rod 73 will actively pull the ball head connecting rod 7 under the pullback action of the spring 74. 3 is tightened toward the inner side of the left end of the double tube 7, and then the double chimeric body 72 is fitted and installed with the corresponding embedding groove 712 and the open hoop 71 to complete the assembly of the left end of the double tube 7 and the open hoop 71 at its left end; then a set of ball head connecting rods 73 connected to the right end of the double tube 7 are inserted into the ball head clamping groove 711 from the embedding groove 712. During this period, the ball head connecting rod 73 will actively tighten the ball head connecting rod 73 toward the inner side of the right end of the double tube 7 under the pulling action of the spring 74, and then the double chimeric body 72 is fitted and installed with the corresponding embedding groove 712 and the open hoop 71 to complete the assembly of the right end of the double tube 7 and the open hoop 71 at its right end, and the portion where the double tube 7 and the double-layer tarpaulin 1 are inserted is waterproofed. After the above assembly is completed, the middle part of the double tube 7 provides support for the bottom of the long prism 8.

[0046] Then the top of the second diagonal brace rod 48 is tilted and passed through the double-layer tarpaulin 1 in sequence, through the thickened ring 45 at the right end of the first cross bar 41, through the reinforcement tube 13, and then through the thickened ring 45 on the surface of the second cross bar 42 and close to the left end, until the top of the second diagonal brace rod 48 corresponds to the surface of the third cross bar 43 and close to the left end. The plug cap 432 is inserted into the hoop 431, so that the curved surface notch at the top of the second diagonal brace rod 48 fits on the hoop 431 on the surface of the third cross bar 43; during this period, when the second diagonal brace rod 48 passes through the first cross bar 41 and the second cross bar 42, the second diagonal brace rod 48 is tilted and displaced as a whole toward the direction of the left end of the third cross bar 43, so that the steel ball 441 corresponds to the entrance and smoothly enters the guide rail 47, and then translates toward the right end of the third cross bar 43 along the horizontal guide of the guide rail 47, so that the steel ball 441 is away from the entrance of the guide rail 47 to prevent derailment, and at the same time, the top of the second diagonal brace rod 48 is inserted into the plug cap 432.

[0047] Then, the reverse operation is adopted to sequentially pass the top of the diagonal brace rod 44 through the double-layer tarpaulin 1, through the thickened ring 45 at the left end of the first cross bar 41, through the square frame 14 on the reinforcement tube 13, through the reinforcement tube 13 and the four-rod frame 482, and then through the thickened ring 45 on the surface of the second cross bar 42 and close to the right end, until the top of the diagonal brace rod 44 corresponds to the plug cap 432 on the surface of the third cross bar 43 and close to the right end and is inserted into the hoop 431, so that the curved notch at the top of the diagonal brace rod 44 fits the third cross bar 4 3; during this period, when the diagonal support rod 48 passes through the first cross bar 41 and the second cross bar 42, similarly, the diagonal support rod 48 is horizontally displaced toward the right end of the third cross bar 43, so that the steel ball 441 smoothly enters the guide rail 47 corresponding to the entrance, and then translates toward the left end of the third cross bar 43 along the horizontal guide of the guide rail 47, and the steel ball 441 is away from the entrance of the guide rail 47 to prevent derailment, and at the same time, the top of the diagonal support rod 48 is inserted into the plug cap 432.

[0048] Then the threaded wheel rod 9 is sequentially passed through the front sleeve 12, the four-rod frame 482, the rectangular frame 442, and the double-headed screw ring 10 inside the reinforcement tube 13 to be exposed from the inside of the double-layer tarpaulin 1. During this period, the threaded wheel rod 9 is threadedly installed with the reinforcement tube 13 and the double-headed screw ring 10 in turn. After the threaded wheel rod 9 is installed out of the inner thread of the double-headed screw ring 10, it is locked by inserting a card wire to prevent the threaded wheel rod 9 and the double-headed screw ring 10 from loosening the threaded installation position, and to prevent the threaded wheel rod 9 from falling off from the double-headed screw ring 10; the rectangular frame 442 and the four-rod frame 482 are jointly fixed by the threaded wheel rod 9 The positioning lock is on the inner side of the reinforcement tube 13, and the steel ball 441 on the surface of the diagonal strut 1 44 and the diagonal strut 2 48 and close to the first cross bar 41 is installed on the inner side of the guide rail 47. Under the action of the gravity of the diagonal strut 1 and the double-layer tarpaulin 1, the bottom ends of the cross structure formed by the diagonal strut 1 44 and the diagonal strut 2 48 are separated from each other, and the angle becomes larger, which will not easily cause the steel ball 441 to reach the entrance of the guide rail 47 and detach from the inner side of the guide rail 47, thereby completing the assembly of the frame assembly 4 on the inner side of the double-layer tarpaulin 1.

[0049] Then in Figure 1On the front and rear surfaces of the double-layer tarpaulin 1 shown in the figure, the two ends of the limit plate 5 are sequentially inserted into the ends of the first cross bar 41 and the second cross bar 42, the ends of the second cross bar 42 and the third cross bar 43, the ends of the third cross bar 43 and the cross beam 6, and the ends between two adjacent cross beams 6. Then, the hoop 412 is engaged with the ring groove 411 so that the hoop 412 is blocked on the front side of the limit plate 5, the anti-loosening gasket 413 is set on the front and rear ends of the first cross bar 41, the second cross bar 42, the third cross bar 43 and the cross beam 6, and then the inner screw 414 is threadedly installed with the external sleeve 415 on the first cross bar 41, the second cross bar 42, the third cross bar 43, and the cross beam 6. The front and rear ends of the rod 43 and the crossbeam 6 threadably lock the limit plate 5 in the frame position of the connection between the double-layer tarpaulin 1 and the elastic frame tarpaulin 2, so that the assembly of the limit plate 5 and the above-mentioned structural components forms a door frame-shaped window at the front and back of the double-layer tarpaulin 1, providing installation space for the movable and removable tarpaulin 3 to be installed in the space covered by the elastic frame tarpaulin 2. Finally, the movable and removable tarpaulin 3 is installed in the space covered by the elastic frame tarpaulin 2 through a zipper. The above operations complete the assembly work of the tarpaulin device before use. The above operations can also be used as the final finished product assembly work of the tarpaulin device in the factory production stage to provide users with a product that can be directly used.

[0050] When the tarpaulin device is an assembled finished product, it is possible to choose not to assemble the limiting plate 5 and the movable detachable tarpaulin 3, so that the frame tarpaulin structure formed by the assembled double-layer tarpaulin 1, frame assembly 4, crossbeam 6, and double pipe fittings 7 can be rotated around the third crossbar 43, and the frame assemblies 4 on both sides can be folded on the top of the double-layer tarpaulin 1 and stored. Some parts of the tarpaulin device can be assembled in advance, and the assembled parts can be effectively folded and stored, thereby reducing the occupied space and the packaging space. At the same time, it is also convenient for the manufacturer to stack the remaining unassembled limiting plates 5 and movable detachable tarpaulin 3 on the folded components for packaging and transportation together. It is also convenient for the user to quickly install and use the tarpaulin device on the vehicle by completing the final assembly of the limiting plates 5 and the movable detachable tarpaulin 3 after receiving the goods.

[0051] In the subsequent use process, the installation direction of the tarpaulin device and the vehicle can be selectively specified according to the use needs: the first one is, Figure 1As shown, the assembled tarpaulin device is installed as a whole on the vehicle in the same direction as the front and rear positions of the movable detachable tarpaulin 3, and the movable detachable tarpaulin 3 is used as the tarpaulin device to carry out one-way loading and unloading of goods at the rear of the vehicle along the movable plate at the rear of the vehicle. The first cross bar 41, the second cross bar 42, the third cross bar 43 and the cross beam 6 with the same length as the vehicle body and the same width as the top width supported by the double-layer tarpaulin 1 are selected for assembly and use, so as to assemble and position the tarpaulin device around the vehicle body; specifically, the left and right side panels of the vehicle body can be welded with corner seats in advance, and the welding positions of the corner seats can be specifically corresponding to the front and rear end positions of the first cross bar 41, the second cross bar 42 and the third cross bar 43, and then the three rod structures are passed through the hole structure on the corner seats, and then the rod bolts are installed and locked on the corner seats by the inner screw rod 414 and the outer sleeve 415, so as to realize the assembly and use of the tarpaulin device around the vehicle body.

[0052] The second type, such as Figure 1 As shown, the assembled tarpaulin device is installed in a direction perpendicular to the front and rear directions of the vehicle according to the front and rear positions of the movable detachable tarpaulin 3, so that the tarpaulin device is installed as a whole on the vehicle, and the movable detachable tarpaulin 3 corresponds to the left and right sides of the vehicle compartment panels, providing a two-way loading and unloading installation and use mode for the vehicle on the left and right sides; the first cross bar 41, the second cross bar 42, the third cross bar 43 and the cross beam 6 with the same width as the compartment are selected to assemble the tarpaulin device as a whole on the vehicle, and the length of the compartment is the same as the double-layer tarpaulin. The tarpaulin device with the same top length supported by the cloth 1 is assembled and used; specifically, the upper corner seats can be welded in advance on the front and rear compartment plates of the compartment, that is, the compartment plates in the same direction as the straight line where the front and rear ends of the vehicle are located, and the welding positions of the corner seats are specifically corresponding to the front and rear end positions of the first cross bar 41, the second cross bar 42, and the third cross bar 43, and then these three rod structures are passed through the hole structure on the corner seats, and then these rod bolts are installed and locked on the corner seats by the inner screw rod 414 and the outer sleeve 415, so as to realize the assembly and use of the tarpaulin device around the compartment.

[0053] By installing and using the tarpaulin device in different positions of the car body, and combining the combined design of the movable detachable tarpaulin and the double-layer tarpaulin, a variety of combined use modes are provided to users, which is convenient for unloading. The movable detachable tarpaulin 3 can also be removed and used in a semi-shielded manner to increase ventilation inside the car body while ensuring shielding and protection of the top of the cargo, thereby adapting to the needs of different weather and environments, and improving the flexibility and convenience of the tarpaulin device.

[0054] In the first mode of use, the long prism 8 is in the same direction as the vehicle's forward movement, so that the tarpaulin device installed in the vehicle compartment can use the external force of the vehicle starting and braking as well as the vehicle on bumpy roads to help the double-layer tarpaulin 1 to dump the rainwater and dirt accumulated on the top of the double-layer tarpaulin 1 along the straight line direction where the front and rear of the vehicle are located. In this way, the foreign matter accumulated on the top of the double-layer tarpaulin 1 can be cleaned up by itself, reducing the load on the top of the double-layer tarpaulin 1 and ensuring the safe use of the double-layer tarpaulin 1.

[0055] In the second usage mode, the long prism 8 is perpendicular to the forward direction of the vehicle. At this time, the tarpaulin device installed in the vehicle compartment can use the external force of the vehicle starting and braking as well as the vehicle on bumpy roads to help the double-layer tarpaulin 1 to dump the rainwater and dirt accumulated on the top of the double-layer tarpaulin 1 in a direction perpendicular to the straight line between the front and rear of the vehicle. In this way, foreign matter accumulated on the top of the double-layer tarpaulin 1 is cleared, the load on the top of the double-layer tarpaulin 1 is reduced, and the safe use of the double-layer tarpaulin 1 is ensured.

[0056] The tarpaulin device can provide an all-round shielding protection for the carriage, and can effectively protect the goods in the carriage from being polluted and invaded by rain and foreign objects, ensuring the safe storage of the items contained inside.

[0057] Through the installation operation described above, after the corner seat is welded to the corresponding position on the car body, in the subsequent use, it is only necessary to open the zipper to remove the cover of the movable detachable tarpaulin 3 on the interior of the car body, so as to realize the function of convenient loading and unloading of goods into the car body.

[0058] At the same time, when the tarpaulin device is not in use, the bolt structure on the corner seat can be manually removed, and the assembly support of the limit plate 5 on both ends of each rod-like structure can be removed, so that the tarpaulin device can be folded upward around the third cross bar 43 to fold the tarpaulin device as a whole and store it on the frame on the top of the car. In particular, it can be folded and stored. When the car itself has a door frame-shaped bracket on the top, the tarpaulin device can be tied to the top of the car frame with a rope, so that the interior space of the car can be exposed and the ventilation measures for the interior space of the car can be implemented. When the car itself does not have a door frame-shaped bracket, the tarpaulin device can be more conveniently folded and stored inside the car for storage and cleaning.

[0059] During use of the tarpaulin device, the multiple triangular stabilizing structures formed by the first cross bar 41, the second cross bar 42, the third cross bar 43, the first diagonal support bar 44 and the second diagonal support bar 48 constituting the frame assembly 4 can be utilized to enhance the stable supporting performance of the tarpaulin device.

[0060] At the same time, the design of thickened ring 45 and thick splint 46 is also utilized, and the guide rail 47 is utilized to provide a sliding motion track for the steel ball 441. Combined with the limiting guidance of the top of the diagonal strut 1 44 and the diagonal strut 2 48 by the plug cap 432, the translational activity range between the first cross bar 41 and the second cross bar 42 during the intersection of the diagonal strut 1 44 and the diagonal strut 2 48 is increased, and a slight translational movement can occur within the horizontal guiding range of the guide rail 47. While ensuring the stable supporting performance of the frame assembly 4 for the double-layer tarpaulin 1, the double-layer tarpaulin 1 itself is given deformability, and will not be rigidly pulled or collided with strong winds or foreign objects, which can enhance the tearing resistance of the tarpaulin device when encountering strong winds or foreign objects.

[0061] Through multiple reinforcement designs, such as the corresponding structural designs of reinforcement tubes, thickened rings, and diagonal braces, the stability of the tarpaulin is ensured in various weather conditions, reducing damage caused by wind or other external forces, and reflecting the stability and safety of the structure.

[0062] The second embodiment is based on the first embodiment. Figures 1 to 8 As shown, the front and rear ends of the long prism 8 are both installed with isosceles trapezoidal frames 16, the isosceles trapezoidal frames 16 are embedded with the limiting plates 5, and the side of the isosceles trapezoidal frame 16 facing the long prism 8 is connected with a latch head 161, and the isosceles trapezoidal frame 16 is inserted into the long prism 8 through the latch head 161. The extension length of the two ends of the long prism 8 is extended by the isosceles trapezoidal frame 16, so as to prevent rainwater and foreign objects from directly adhering to the surface of the elastic frame tarpaulin 2 and dirtying the elastic frame tarpaulin 2, and also prevent rainwater and foreign objects from dirtying the surface of the car body.

[0063] In use, while using the double pipe fitting 7 to clamp and combine two adjacent cross beam rods 6 through the opening hoop 71, the middle part of the double pipe fitting 7 provides support for the bottom ends of the long prism 8, forming a continuous support structure in the shape of a Chinese character 'Ri' at the top of the double-layer tarpaulin 1, dividing the top of the double-layer tarpaulin 1 into independent spaces to separately hold the rainwater and foreign objects falling on the top of the double-layer tarpaulin 1. And due to the structural design that the long prism 8 protrudes from the top of the double-layer tarpaulin 1, the accumulated rainwater is guided and separated along the long prism 8 towards the long edge of the double-layer tarpaulin 1, preventing the concentrated pressure of the continuously accumulated rainwater on the top of the double-layer tarpaulin 1. Also, with the help of the isosceles trapezoidal frame 16 inserted at the end of the long prism 8, the drainage path length of the long prism 8 in the width direction can be extended to assist in guiding the rainwater and foreign objects outside the carriage. At the same time, inside the carriage, standing directly below the position corresponding to the long prism 8, a pole can be used to jack up the middle part of the long prism 8, so as to push and clean up the rainwater and foreign objects accumulated on both sides of the long prism 8 out of the carriage along the guidance of the long prism 8; and during the use of the tarpaulin device together with the vehicle, with the help of the shaking of the carriage, it can assist the rainwater and foreign objects on the top of the double-layer tarpaulin 1 to fall off by themselves.

[0064] The third embodiment, on the basis of the first and second embodiments, please refer to Figures 10 to 12 As shown, opening hoops 71 are installed at both ends of the double pipe fitting 7, and the opening hoops 71 are fitted and installed with the double-layer tarpaulin 1 through the sleeve part 11. The double pipe fitting 7 is inserted into the double-layer tarpaulin 1 and the insertion part is waterproofed. The opening hoops 71 are sleeved on the cross beam rods 6, and double inlays 72 are fitted and installed on the surface of the opening hoops 71. A group of ball joint rods 73 are installed between the double inlays 72 and the opening hoops 71. One end of the ball joint rod 73 away from the double inlay 72 is connected to a spring 74, and the spring 74 is connected to the double pipe fitting 7.

[0065] Threaded rails 701 are installed on the inner sides of the middle parts at both ends of the double pipe fitting 7. Threaded parts 731 are fixedly installed on the surface of the ball joint rods 73. Ball head card slots 711 and embedding slots 712 are opened on the surface of the opening hoops 71 and near the double inlays 72. The ball head card slots 711 communicate with the embedding slots 712. The ball joint rods 73 are fitted and installed with the opening hoops 71 through the cooperation of the ball head card slots 711 and the double inlays 72. The double inlays 72 are fitted and installed with the opening hoops 71 through the embedding slots 712. The ball joint rods 73 are threadedly installed with the double pipe fitting 7 through the cooperation of the threaded parts 731 and the threaded rails 701. The double inlays 72 protrude from the top of the double-layer tarpaulin 1.

[0066] When in use, the ball joint rod 73 itself is elastically connected to the double pipe fitting 7 through the spring 74, and the threaded installation of the threaded portion 731 and the threaded rail 701 is used to partially twist and store the ball joint rod 73 inside the double pipe fitting 7, so that after the threaded installation portion of the threaded portion 731 and the threaded rail 701 is twisted, the ball joint rod 73 itself can not only elastically expand and contract on the axis with the double pipe fitting 7 through the spring 74, but also can radially block the threaded portion 731 on the axis with the help of the threaded rail 701, thereby elastically extending the ball joint rod 73 inside the double pipe fitting 7 The movable space is limited and blocked, which can prevent the spring 74 from being over-tensioned and deformed, and prevent the ball head connecting rod 73 from easily falling off from the double-tube fitting 7, ensuring that the double-tube fitting 7 with the ball head connecting rod 73 can provide a stable support for the bottom of the long prism 8 with the help of assembly with the open hoop 71, and at the same time, it can also assist in supporting the stability and stability between two adjacent cross beams 6 when installed on the top of the double-layer tarpaulin 1, so that there will be no rigid fixed locking installation between the two adjacent cross beams 6, and no excessive shaking will occur relatively.

[0067] The top of the double-layer tarpaulin 1 supported by the crossbeam 6, the double tube 7 and the long prism 8 can provide a stable supporting tarpaulin structure with a certain elastic shaking for the top of the vehicle-mounted tarpaulin. It can not only shake slightly within a safe range as the vehicle moves forward to offset the impact and shaking of the tarpaulin structure by external forces during the vehicle's forward movement; it can also shake down foreign objects accidentally accumulated on the top of the tarpaulin structure, so that the tarpaulin structure can cleverly combine the characteristics of its own structural installation to cleverly utilize the shaking force caused by the bumps on the road when the vehicle moves forward, so as to achieve self-cleaning of the dirt on its top part.

[0068] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
