Description

Technical Field

[0001] This utility model relates to the field of cargo box manufacturing technology, and in particular to a top cover assembly for a box-type cargo box. Background Technology

[0002] The roof assembly of a box truck is a crucial structural component of the truck's top. It acts like a "roof" for the truck, providing shelter and protection for the loaded goods. The roof assembly is an indispensable part of the box truck and plays a key role in the safety of cargo transportation and the overall performance of the truck.

[0003] Traditional designs often lack effective mechanical locking mechanisms, relying more on friction, simple hooks, or buckles to secure the lid. This design is prone to failure when the vehicle encounters vibrations, bumps, or uneven external forces during operation, leading to the lid opening unexpectedly. This can not only cause goods to scatter but also poses serious safety hazards. In addition, the opening and closing methods of traditional lids are usually quite complex, requiring operators to expend considerable effort and time to complete.

[0004] Therefore, those skilled in the art have provided a top cover assembly for a van to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a top cover assembly for a van. Through the forward and reverse rotation of a bidirectional threaded rod, the locking blocks on both sides can be driven to move simultaneously outward or inward. When locking is required, the locking blocks move outward, pass through the sliding groove and the through groove, and finally enter the connecting groove to engage with the locking groove on the connecting rod. This engagement provides a mechanical locking mechanism, effectively preventing the cover from accidentally opening during transportation or loading / unloading. When unlocking is required, the bidirectional threaded rod reverses, the locking blocks move inward, disengage from the locking groove, and the cover can be easily opened. This locking mechanism is relatively independent and can adapt to covers and the front end of the van body of different sizes and designs. By adjusting the size and position of the relevant components, it can be easily applied to different vehicle models.

[0006] To achieve the above objectives, this utility model provides a top cover assembly for a van-type cargo box, including a cargo box body and a cover. A first mounting block is fixedly connected to the center of the front end of the cover. Connecting rods are fixedly connected to both sides of the lower surface of the first mounting block, and each connecting rod has a snap-fit ​​groove in its center. A second mounting block is fixedly connected to the center of the front end of the cargo box body. Connecting grooves are formed on both sides of the upper outer wall of the front end of the second mounting block. Two sliding grooves are formed in the center of the outer wall of the front end of the second mounting block. The inner wall of each sliding groove on the side away from the center of the second mounting block has a... The upper part of the front outer wall of the cargo box body is fixedly connected to two fixing blocks. A rotating part is provided on one side of one of the fixing blocks, and a bidirectional threaded rod is fixedly connected to the other side of the rotating part through the fixing block. Sliding blocks are threaded to both sides of the outer wall of the bidirectional threaded rod. A snap-fit ​​block is fixedly connected to the rear end of each sliding block. The outer wall of the connecting rod is tightly fitted with the inner wall of the connecting groove. The side of the snap-fit ​​block away from the middle of the second mounting block passes through the sliding groove and the through groove into the interior of the connecting groove and snaps into the inner wall of the snap-fit ​​groove.

[0007] Through the above technical solution, the forward and reverse rotation of the bidirectional threaded rod can drive the locking blocks on both sides to move outward or inward simultaneously. When locking is required, the locking blocks move outward, pass through the sliding groove and the through groove, and finally enter the connecting groove and engage with the locking groove on the connecting rod. This engagement provides a mechanical locking mechanism that can effectively prevent the lid from being accidentally opened during transportation or loading and unloading. When unlocking is required, the bidirectional threaded rod reverses, the locking blocks move inward, disengage from the locking groove, and the lid can be easily opened. The rotating parts can be rotated using tools, facilitating manual operation. This locking mechanism is relatively independent and can adapt to lids and the front end of the cargo box body of different sizes and designs. By adjusting the size and position of the relevant components, it can be easily applied to different vehicle models.

[0008] Furthermore, the lower part of the rear end of the box cover is hinged to the upper part of the rear end of the cargo box body via a hinge. A sealing gasket is fixedly connected to the lower surface of the box cover, and the lower end of the sealing gasket is tightly fitted to the upper surface of the cargo box body. The lower surface of the first mounting block is tightly fitted to the upper surface of the second mounting block. Multiple electric push rods are hinged to both sides of the bottom surface of the cargo box body via hinges. The output ends of the multiple electric push rods are all hinged to both sides of the lower surface of the box cover via hinges. Arc-shaped plates are fixedly connected to both sides of the lower surface of the rear end of the box cover, and the outer walls of the arc-shaped plates are slidably fitted to the inner walls of both sides of the rear end of the cargo box body.

[0009] The above technical solution provides a fixed rotating axis through a hinged connection, ensuring that the lid rotates around a fixed point during opening and closing, resulting in structural stability and preventing wobbling or displacement. The sealing gasket effectively prevents rainwater, snow, dust, etc., from entering the cargo compartment through the gap between the lid and the cargo compartment body, keeping the goods clean and dry. The opening and closing of the lid can be automatically controlled by a multi-section electric push rod, reducing the labor intensity of manual operation. In addition, the arc-shaped plate slides along the arc-shaped track on the inner wall of the rear end of the cargo compartment body when the lid is opened and closed, playing a good guiding role and ensuring that the lid closes smoothly and accurately to the correct position.

[0010] Furthermore, the two sides of the bidirectional threaded rod are rotatably connected to the adjacent two sides of the fixed block, respectively;

[0011] By using the above technical solution, and by rotating the two sides of the bidirectional threaded rod to the two sides of the fixed block respectively, it is ensured that the power can be stably and efficiently transmitted from the rotating parts to the bidirectional threaded rod.

[0012] Furthermore, a reinforcing plate is provided inside the box lid;

[0013] Through the above technical solution, the reinforcing plate can effectively resist the bending and deformation of the box cover under force, prevent the box cover from denting or being damaged due to insufficient strength. The reinforcing plate can distribute the force acting on the surface of the box cover more evenly to a larger structural area, thereby improving the overall rigidity of the box cover and making it less prone to deformation.

[0014] Furthermore, the side of the through groove away from the center of the second mounting block is connected to the interior of the connecting groove.

[0015] The above technical solution and design ensure that the snap-fit ​​block can accurately enter the connecting slot after being moved to the predetermined position.

[0016] Furthermore, all the snap-fit ​​blocks are located inside the sliding groove, and the outer walls of the snap-fit ​​blocks are slidably fitted with the inner walls of the sliding groove and the through groove;

[0017] The above technical solution ensures that the snap-fit ​​block can only move along the axis of the sliding groove in the horizontal direction. When the snap-fit ​​block needs to pass through the through groove, its outer wall is also in close contact with the inner wall of the through groove. This ensures that the snap-fit ​​block will not shift its position during the process of entering or exiting the connecting groove, thus guaranteeing the accuracy of the snap-fit ​​process.

[0018] This utility model has the following beneficial effects:

[0019] This utility model proposes a top cover assembly for a van-type cargo box. By reversing the bidirectional threaded rod, the locking blocks on both sides can be driven to move outward or inward simultaneously. When locking is required, the locking blocks move outward, pass through the sliding groove and the through groove, and finally enter the connecting groove and engage with the locking groove on the connecting rod. This engagement provides a mechanical locking mechanism that effectively prevents the lid from being accidentally opened during transportation or loading and unloading. When unlocking is required, the bidirectional threaded rod reverses, the locking blocks move inward, disengage from the locking groove, and the lid can be easily opened. This locking mechanism is relatively independent and can adapt to lids and the front end of the cargo box body of different sizes and designs. By adjusting the size and position of the relevant components, it can be easily applied to different vehicle models. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 2 , Figure 4 and Figure 5 This utility model provides a specific embodiment: a top cover assembly for a box-type cargo box, including a cargo box body 1 and a box cover 2. A first mounting block 3 is fixedly connected to the middle of the front end of the box cover 2. Connecting rods 301 are fixedly connected to both sides of the lower surface of the first mounting block 3. Each connecting rod 301 has a snap-fit ​​groove 302 in the middle. A second mounting block 4 is fixedly connected to the middle of the front end of the cargo box body 1. Connecting grooves 401 are formed on both sides of the upper outer wall of the front end of the second mounting block 4. Two sliding grooves 40 are formed in the middle of the outer wall of the front end of the second mounting block 4. 2. The inner wall of the sliding groove 402 on the side away from the middle of the second mounting block 4 is provided with a through groove 403. Two fixing blocks 101 are fixedly connected to the upper part of the front outer wall of the cargo box body 1. A rotating part 5 is provided on one side of one fixing block 101. The other side of the rotating part 5 passes through the fixing block 101 to the other side of the fixing block 101 and is fixedly connected to a bidirectional threaded rod 501. Sliding blocks 502 are threadedly connected to both sides of the outer wall of the bidirectional threaded rod 501. A snap-fit ​​block 503 is fixedly connected to the rear end of each sliding block 502. The connecting rod 301 The outer walls of both sides are tightly fitted to the inner wall of the connecting groove 401. The side of the snap-fit ​​block 503 away from the middle of the second mounting block 4 passes through the sliding groove 402 and the through groove 403 into the interior of the connecting groove 401 and engages with the inner wall of the snap-fit ​​groove 302. By rotating the bidirectional threaded rod 501 in both directions, the snap-fit ​​blocks 503 on both sides can be driven to move outward or inward simultaneously. When locking is required, the snap-fit ​​block 503 moves outward, passes through the sliding groove 402 and the through groove 403, and finally enters the connecting groove 401 and engages with the snap-fit ​​groove 302 on the connecting rod 301. This locking mechanism provides a mechanical locking system that effectively prevents the lid 2 from being accidentally opened during transport or loading / unloading. When unlocking is required, the bidirectional threaded rod 501 reverses, and the locking block 503 moves inward, disengaging from the locking groove 302, allowing the lid 2 to be easily opened. The rotating part 5 can be rotated using a tool for easy manual operation. This locking mechanism is relatively independent and can adapt to lids 2 and the front end of the cargo box body 1 of different sizes and designs. By adjusting the size and position of the relevant components, it can be easily applied to different vehicle models.

[0029] Reference Figure 1 and Figure 2A top cover assembly for a box-type cargo box includes a cargo box body 1 and a cover 2. A first mounting block 3 is fixedly connected to the middle of the front end of the cover 2. Connecting rods 301 are fixedly connected to both sides of the lower surface of the first mounting block 3. Each connecting rod 301 has a locking groove 302 in the middle. A second mounting block 4 is fixedly connected to the middle of the front end of the cargo box body 1. Connecting grooves 401 are formed on both sides of the upper outer wall of the front end of the second mounting block 4. Two sliding grooves 402 are formed in the middle of the outer wall of the front end of the second mounting block 4. The sliding grooves 402 are far from the second mounting block 1. The inner wall of one side of the middle part of the mounting block 4 is provided with a through groove 403. Two fixing blocks 101 are fixedly connected to the upper part of the front outer wall of the cargo box body 1. A rotating part 5 is provided on one side of one fixing block 101. The other side of the rotating part 5 passes through the fixing block 101 to the other side of the fixing block 101 and is fixedly connected to a bidirectional threaded rod 501. Sliding blocks 502 are threadedly connected to both sides of the outer wall of the bidirectional threaded rod 501. A snap-fit ​​block 503 is fixedly connected to the rear end of each sliding block 502. The outer wall of the connecting rod 301 is connected to the connecting groove 4. The inner wall of 01 fits tightly. The side of the locking block 503 furthest from the middle of the second mounting block 4 passes through the sliding groove 402 and the through groove 403 to the interior of the connecting groove 401 and engages with the inner wall of the locking groove 302. By rotating the bidirectional threaded rod 501, the locking blocks 503 on both sides can be driven to move outwards or inwards simultaneously. When locking is required, the locking block 503 moves outwards, passes through the sliding groove 402 and the through groove 403, and finally enters the connecting groove 401, engaging with the locking groove 302 on the connecting rod 301. This... The snap-fit ​​mechanism provides a mechanical locking system that effectively prevents the lid 2 from being accidentally opened during transport or loading / unloading. When unlocking is required, the bidirectional threaded rod 501 reverses, and the snap-fit ​​block 503 moves inward, disengaging from the snap-fit ​​groove 302, allowing the lid 2 to be easily opened. The rotating part 5 can be rotated using a tool for easy manual operation. This locking mechanism is relatively independent and can adapt to lids 2 and the front end of the cargo box body 1 of different sizes and designs. By adjusting the size and position of the relevant components, it can be easily applied to different vehicle models.

[0030] Reference Figure 2 , Figure 3 and Figure 4The two sides of the bidirectional threaded rod 501 are rotatably connected to the adjacent sides of the fixed block 101. By rotatably connecting the two sides of the bidirectional threaded rod 501 to the two sides of the fixed block 101, it is ensured that the power can be stably and efficiently transmitted from the rotating part 5 to the bidirectional threaded rod 501. The inside of the box cover 2 is provided with a reinforcing plate 203. The reinforcing plate 203 can effectively resist the bending and deformation of the box cover 2 under force, and prevent the box cover 2 from denting or being damaged due to insufficient strength. The reinforcing plate 203 can distribute the force acting on the surface of the box cover 2 more evenly to a larger structural area, thereby improving the overall rigidity of the box cover 2 and making it less prone to deformation. The through groove 403 is far away from the second mounting block 4. One side of each part is connected to the interior of the connecting groove 401. This design ensures that the snap-fit ​​block 503 can accurately enter the connecting groove 401 after moving to the predetermined position. The snap-fit ​​blocks 503 are all located inside the sliding groove 402. The outer wall of the snap-fit ​​block 503 slides and fits against the inner wall of the sliding groove 402 and the through groove 403. This design ensures that the snap-fit ​​block 503 can only move along the axis of the sliding groove 402 in the horizontal direction. When the snap-fit ​​block 503 needs to pass through the through groove 403, its outer wall also fits tightly against the inner wall of the through groove 403. This ensures that the position of the snap-fit ​​block 503 will not shift during the process of entering or exiting the connecting groove 401, thus ensuring the accuracy of the snap-fit ​​process.

[0031] Working principle: First, the lid 2 is closed, but the front locking mechanism is unlocked. The locking block 503 is stationary in the sliding groove 402. When it is necessary to lock the front, the operator uses a tool to rotate the rotating part 5 in the forward direction. This drives the bidirectional threaded rod 501 to rotate. The threads on both sides of the bidirectional threaded rod 501 synchronously drive the sliding block 502 and its connected locking block 503 to move outward horizontally. The locking block 503 slides smoothly along the sliding groove 402, accurately passes through the through groove 403, and finally enters the interior of the connecting groove 401. Thanks to the tight sliding fit between the outer wall of the locking block 503 and the inner walls of the sliding groove 402 and the through groove 403, the locking block 503 remains stable during movement and will not shift. This ensures the accuracy of the locking process. When the locking block 503 moves to the end of the connecting groove 401, its end precisely engages with the locking groove 302 on the connecting rod 301 below the first mounting block 3, thereby firmly locking the front end of the box cover 2 and effectively preventing the box cover 2 from accidentally opening during transportation or loading and unloading. Conversely, when it is necessary to unlock the locking mechanism... When the operator simply rotates the rotating part 5 in the opposite direction, the bidirectional threaded rod 501 will reverse, driving the locking block 503 to move horizontally inward, allowing it to smoothly disengage from the locking groove 302 of the connecting rod 301. The locking block 503 then retracts into the sliding groove 402, thus unlocking the front locking mechanism. When it is necessary to open the box cover 2, the operator extends the multi-section electric push rod 102 via an external controller, smoothly lifting the box cover 2 to a convenient working height. At this time, the box cover 2 can swing smoothly upward around its rear hinge. When the lid 2 is opened, the arc-shaped plate 202 on the lower rear surface of the lid 2 slides against the inner wall of the cargo box, ensuring a smooth and stable opening process. The reinforcing plate 203 inside the lid 2 acts like a skeleton, ensuring the overall structural strength and rigidity of the lid 2 and preventing it from deforming under stress. After the loading and unloading operation is completed, the lid 2 is closed again, and the multi-section electric push rod 102 is operated again to retract it, so that the sealing gasket 201 on the lower surface of the lid 2 is tightly attached to the upper surface of the cargo box body 1, ensuring a good sealing effect.

Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
