Description

Technical Field

[0001] This application relates to the field of pickup truck cargo box technology, and more specifically, to a height-adjustable pickup truck cargo box structure. Background Technology

[0002] Pickup trucks, as multi-purpose vehicles capable of carrying both passengers and cargo, are widely used in freight transportation, engineering operations, agricultural production, and off-road driving due to their flexible application scenarios and strong load-bearing capacity. In their structural design, the cargo box, as a core cargo-carrying component, directly affects the vehicle's practicality and operational efficiency. However, traditional pickup truck cargo boxes mostly adopt an integrated structure that is fixedly connected to the chassis, meaning the cargo box is rigidly fixed to the chassis assembly by welding or bolts. The relative height between the cargo box and the chassis cannot be adjusted, which has gradually revealed many limitations in practical applications. When using forklifts, loading and unloading machines and other equipment to move large goods, if the height of the cargo box does not match the height of the equipment forks, additional auxiliary tools such as wooden boards and metal frames are required. This not only increases the work process, but may also cause the goods to tilt or fall due to the height difference, posing a safety hazard. At the same time, for small goods, if the cargo box of fixed height is too high, manual handling requires repeated bending or tiptoeing, which can easily cause back and leg strain with long-term operation. Therefore, there is an urgent need for a height-adjustable pickup truck cargo box structure. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, this application provides a height-adjustable pickup truck cargo box structure that achieves cargo box height adjustment through a simple mechanical structure.

[0005] This application provides a height-adjustable pickup truck cargo box structure, including a frame, a cargo box, frame end mounts, cargo box end mounts, and adjusting bolts. The frame is fixedly connected to the pickup truck chassis; the cargo box is mounted on the frame; multiple frame end mounts protrude at intervals around the frame, each frame end mount having a box-shaped structure forming a receiving cavity, and having multiple first bolt holes spaced vertically on both sides; multiple cargo box end mounts protrude from the bottom of the cargo box corresponding to the positions of the frame end mounts, forming a convex pillar structure adapted to the receiving cavity, and having multiple second bolt holes spaced vertically on their sides, the hole spacing matching the first bolt holes; multiple adjusting bolts pass through each first bolt hole and the corresponding second bolt hole, locking and fixing the cargo box end mount to the frame end mount.

[0006] In some embodiments, the cargo box end mount and the vehicle frame end mount are clearance-fitted.

[0007] In some embodiments, each adjusting bolt is threaded into the first bolt hole and the second bolt hole, and the end of the adjusting bolt is fitted with a nut.

[0008] In some embodiments, the cargo box is provided with folding handles on its four sides, and the folding handles are connected to the cargo box via a rotating shaft.

[0009] In some embodiments, the device further includes: a plurality of through holes spaced apart on the side wall of the vehicle frame end suspension away from the first bolt hole; a positioning block protruding from the side of the cargo box end suspension away from the second bolt hole, the positioning block being able to extend and retract within each of the through holes; and a spring disposed in the internal cavity of the cargo box end suspension, one end of which is fixedly connected to the bottom of the cargo box end suspension cavity, and the other end of which is fixedly connected to the positioning block.

[0010] In some embodiments, the positioning block can extend into the through hole.

[0011] Compared with the prior art, the technical solution provided in this application includes at least the following technical effects: This application provides a height-adjustable pickup truck cargo box structure that achieves cargo box height adjustment through a simple mechanical structure. Initially, the cargo box is embedded in the receiving cavity of the frame end suspension via a convex structure suspended at the cargo box end. At this time, the adjusting bolts pass through and lock into the corresponding first and second bolt holes. When the cargo box height needs to be adjusted, all adjusting bolts are loosened, allowing relative sliding between the cargo box end suspension and the frame end suspension. The cargo box is then lifted, causing the cargo box end suspension to rise or fall vertically along the receiving cavity of the frame end suspension until the second bolt hole of the cargo box end suspension aligns with the target height first bolt hole of the frame end suspension. After alignment, the adjusting bolts are passed through the aligned bolt holes, and the nuts are tightened sequentially. The preload of the bolts rigidly connects the cargo box end suspension and the frame end suspension. At this point, the height of the cargo box relative to the frame is locked at the target position. Simultaneously, the positioning block can temporarily fix the cargo box. After the cargo box height is positioned, it is then fixed by the adjusting bolts, eliminating the need for continuous force.

[0015] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0017] The following reference Figures 1 to 4 This application describes a height-adjustable pickup truck cargo box structure provided according to some embodiments.

[0018] like Figure 1 , Figure 2 As shown, a height-adjustable pickup truck cargo box structure according to some embodiments of this application includes a frame 1, a cargo box 2, frame end mounts 3, cargo box end mounts 4, and adjusting bolts 5. The frame 1 is fixedly connected to the pickup truck chassis; the cargo box 2 is mounted on the frame 1; multiple frame end mounts 3 are spaced out along the perimeter of the frame 1, each frame end mount 3 having a box-shaped structure forming a receiving cavity, and multiple first bolt holes 31 are spaced out on both sides along the vertical direction; multiple cargo box end mounts 4 are protruding from the bottom of the cargo box 2 corresponding to the positions of the frame end mounts 3, forming a protruding pillar structure adapted to the receiving cavity, and multiple second bolt holes 41 are spaced out on the sides along the vertical direction, the hole spacing matching the first bolt holes 31; multiple adjusting bolts 5 pass through each first bolt hole 31 and the corresponding second bolt hole 41, locking and fixing the cargo box end mount 4 to the frame end mount 3.

[0019] In this embodiment, in the initial state, the cargo box 2 is embedded into the receiving cavity of the frame end suspension 3 through the protruding structure of the cargo box end suspension 4. At this time, the adjusting bolt 5 passes through the first bolt hole 31 and the second bolt hole 41 at the corresponding positions and is locked. When it is necessary to adjust the height of the cargo box 2, all the adjusting bolts 5 are loosened, so that the cargo box end suspension 4 and the frame end suspension 3 can slide relative to each other. The cargo box 2 is lifted, so that the cargo box end suspension 4 rises or falls vertically along the receiving cavity of the frame end suspension 3 until the second bolt hole 41 of the cargo box end suspension 4 is aligned with the target height first bolt hole 31 of the frame end suspension 3. After alignment, the adjusting bolt 5 is passed through the aligned bolt holes, and the nuts are tightened in sequence. The preload of the bolts rigidly connects the cargo box end suspension 4 and the frame end suspension 3. At this time, the height of the cargo box 2 relative to the frame 1 is locked at the target position. The height adjustment of the cargo box 2 is achieved through only a simple mechanical structure.

[0020] In some possible embodiments, such as Figure 3 As shown, the cargo box end suspension 4 and the frame end suspension 3 are clearance fit.

[0021] In this embodiment, the clearance fit provides space for the cargo box end suspension 4 to slide vertically along the cavity of the frame end suspension 3, avoiding jamming caused by size error or assembly error. When adjusting the height of the cargo box 2, the protrusion can smoothly rise and fall along the inner wall of the cavity without having to overcome the interference friction.

[0022] In some possible embodiments, such as Figure 2 As shown, each adjusting bolt 5 is threadedly engaged with the first bolt hole 31 and the second bolt hole 41, and a nut is fitted at the end of the adjusting bolt 5.

[0023] In this embodiment, after the adjusting bolt 5 is screwed into the first bolt hole 31 and the second bolt hole 41, the contact surfaces of the frame end suspension 3 and the cargo box end suspension 4 are pressed together by adjusting the bidirectional clamping force of the head of the adjusting bolt 5 and the nut, which greatly improves the shock resistance of the connection.

[0024] In some possible embodiments, such as Figure 2 As shown, the cargo box 2 has folding handles 6 on its four sides, and the folding handles 6 are connected to the cargo box 2 via a rotating shaft.

[0025] In this embodiment, when it is necessary to raise or lower the cargo box 2 to adjust the height, the operator can apply force by unfolding the handle, without having to directly grasp the edge of the cargo box 2, providing a more stable point of force application. In addition, the folding handle 6 is fully embedded in the side wall of the cargo box 2 when not in use, without increasing the external size of the cargo box 2, thus avoiding affecting vehicle parking or passage through narrow spaces.

[0026] In some possible embodiments, such as Figure 2 , Figure 4As shown, it also includes: multiple through holes 32, spaced apart on the side wall of the frame end suspension 3 away from the first bolt hole 31; a positioning block 42, protruding from the side of the cargo box end suspension 4 away from the second bolt hole 41, the positioning block 42 being able to extend and retract within each through hole 32; a spring 43, disposed in the internal cavity of the cargo box end suspension 4, one end being fixedly connected to the bottom of the cavity of the cargo box end suspension 4, and the other end being fixedly connected to the positioning block 42; the positioning block 42 being able to extend into the through hole 32.

[0027] In this embodiment, initially, the positioning block 42 is fully inserted into the corresponding through hole 32 under the pushing force of the spring 43. After loosening the adjusting bolt 5, the operator needs to adjust the height of the cargo box 2, lifting it up or down. The cargo box end suspension 4 drives the positioning block 42 to move synchronously. The end of the positioning block 42 contacts the edge of the through hole 32 and is squeezed, overcoming the elastic force of the spring 43 and contracting into the internal cavity of the cargo box end suspension 4 until it completely exits the current through hole 32. The cargo box 2 moves to the target height, and the positioning block 42 is just aligned with the corresponding through hole 32. At this time, the elastic force of the spring 43 is released, pushing the positioning block 42 to automatically extend into the corresponding through hole 32, which serves to temporarily fix the cargo box 2. After the height of the cargo box 2 is positioned, it is fixed by the adjusting bolt 5 without the need for continuous force support.

[0028] In operation, the height-adjustable pickup truck cargo box structure initially positions the cargo box 2 within the box-shaped cavity of the frame-end suspension 3 via the protruding structure of the cargo box end suspension 4. The two components form a clearance fit. Adjusting bolts 5 pass through the first bolt hole 31 of the frame-end suspension 3 and the second bolt hole 41 of the cargo box end suspension 4. Through the threaded engagement and the bidirectional clamping force of the end nut, the two suspensions are rigidly locked, and the cargo box 2 is stably fixed to the frame 1. At this time, the positioning block 42 extends into the corresponding through hole 32 under the thrust of the spring 43. When the height of the cargo box 2 needs to be adjusted, all adjusting bolts 5 are first loosened. Because the cargo box end suspension 4 and the frame end... The suspension 3 is a clearance fit, and the protrusion can slide smoothly along the inner wall of the cavity. The operator can apply force through the folding handles 6 around the cargo box 2 to raise or lower the cargo box 2, which will drive the suspension 4 at the end of the cargo box to rise and fall synchronously. During this process, the positioning block 42 will be squeezed by the edge of the through hole 32, overcome the elastic force of the spring 43 to retract and exit the current through hole 32. After the cargo box 2 is raised and lowered to the target height, the spring 43 will push the positioning block 42 to automatically extend into the corresponding through hole 32 to achieve temporary fixation of the cargo box 2. At this time, the second bolt hole 41 is aligned with the first bolt hole 31. The operator can tighten the nut by passing the adjusting bolt 5 through its bolt hole to complete the height locking.
