Description

Technical Field

[0001] This application relates to the field of automotive cargo box technology, and in particular to a lightweight, detachable cargo box structure and vehicle for onboard transport. Background Technology

[0002] A pickup truck is a vehicle type that uses a car-like front end and cab while also featuring an open cargo bed. It combines the characteristics of both passenger and commercial vehicles (passenger and cargo transport), exhibiting significant features as a work vehicle for businesses and families. Its diverse construction caters to a wider range of needs, particularly with numerous options for modifying the open cargo bed. Due to the many advantages of pickup trucks, more and more users are using them for self-driving tours and off-road adventures, showing a trend towards functionalizing them like mid-to-high-end sedans and multi-purpose vehicles. To fully utilize the versatility of the open cargo bed, more and more automakers are designing and improving pickup truck beds, with the addition of a cargo box being one of the main areas of improvement.

[0003] Among related technologies, there is a method of directly integrating a multi-functional camping equipment box into an open cargo compartment. This equipment box integrates components such as cabinets, water tanks, luggage racks, ladders, and bed boards. This multi-functional camping equipment box can solve most of the needs of camping users. However, this camping equipment box is large and heavy. Since the camping equipment box is mostly exposed outside the cargo compartment, it results in high wind resistance during driving. At the same time, it is not fully integrated with the internal structure of the pickup truck cargo compartment itself. The assembly and disassembly process is troublesome and time-consuming. For self-driving tours and off-road trips, it brings users a very poor off-road experience. Furthermore, due to long-term driving on bumpy roads in the wild, the structure of the assembled camping equipment box is unstable and is prone to loosening and making noise. Summary of the Invention

[0004] This application aims to propose a lightweight, detachable cargo box structure and vehicle for off-road use, in order to solve the problems of existing technology where pickup trucks equipped with camping equipment boxes are bulky and heavy, have high wind resistance during driving, and are not fully integrated with the internal structure of the pickup truck itself, making the assembly and disassembly process troublesome and time-consuming, and the structure of the camping equipment box is unstable and prone to loosening and making noise.

[0005] To achieve the above objectives, in a first aspect, embodiments of this application provide a vehicle-mounted lightweight detachable cargo box structure for cross-country use, comprising: A combined frame; the combined frame includes a base bracket, a first support rod, a second support rod, a side wall fixing assembly, and a mounting plate; The base bracket includes a first crossbeam, a second crossbeam parallel to the first crossbeam, and a guide support plate connecting the first crossbeam and the second crossbeam at both ends respectively; the first support rod is fixedly connected to the top surfaces of both ends of the first crossbeam, and the second crossbeam is fixedly connected to the top surfaces of the first crossbeam and the second crossbeam respectively; the mounting plate is fixedly connected to the side end face of the first support rod, the end face of the mounting plate away from the first support rod is fixedly connected to the surface of the vehicle side panel, and the side panel fixing assembly is fixedly connected to the side panel surface at the same height as the mounting plate; The first pull-out panel assembly is fixedly installed on the top surface of the guide support plate; The second pull-out panel assembly is coaxial with the first pull-out panel assembly in the vertical direction, and the first support rod and the inner surface of the second support rod are detachably connected to the four corners of the second pull-out panel assembly.

[0006] According to this application, a lightweight, detachable cargo box structure for vehicle-mounted transport utilizes a modular frame constructed from interconnected hollow steel pipes. This reduces the weight of the cargo box structure and facilitates installation and disassembly. The modular frame is fixedly installed inside the open rear cargo compartment of a pickup truck. The bottom and side panels of the modular frame are bolted to the inner wall of the open rear cargo compartment, ensuring structural stability after installation. A double-row, pull-out first pull-out panel assembly is located at the bottom of the modular frame. A second pull-out panel assembly is detachably connected to the top of the modular frame, which is coaxial with the first pull-out panel assembly in the vertical direction. The height of the second pull-out panel assembly is adjustable. The first and second pull-out panel assemblies facilitate storage while further reducing the weight of the cargo box structure. Furthermore, the entire cargo box structure boasts high space utilization, a compact structure, and ease of use. After installation, it exhibits low wind resistance during driving, enhancing the user experience.

[0007] According to some embodiments of this application, the length of the first crossbeam is greater than the length of the second crossbeam. The first crossbeam and the bottom surface of the first crossbeam are provided with a plurality of limiting protrusions at intervals. A plurality of the guide support plates are provided parallel to each other between the first crossbeam and the second crossbeam. By setting the limiting protrusions, the limiting protrusions fit against the bottom surface of the open cargo box, thereby making the structure of the cargo box structure device more stable after installation and preventing the cargo box structure device from moving left and right.

[0008] According to some embodiments of this application, an L-shaped fixing plate is also included. The first support rod is vertically connected to the top surfaces of both ends of the first crossbeam, and the second support rod is vertically connected to the top surface of the middle of the first crossbeam and the second crossbeam. The L-shaped fixing plate is fixedly connected to the connection points of the first support rod and the first crossbeam, and the connection points of the second support rod and the first crossbeam and the second crossbeam. By fixing the L-shaped fixing plate at the connection points of the second support rod and the first crossbeam and the second crossbeam, the right angle formed by the L-shaped fixing plate and each connection point is fitted, thereby strengthening the structural strength of the connection points and ensuring the structural stability of the cargo box structure device after installation.

[0009] According to some embodiments of this application, the first support rod and the second support rod are provided with weight-reducing through holes along the length direction. The longitudinal section structures of the first support rod and the second support rod are the same. The opposite side surfaces of the first support rod and the second support rod are provided with limiting mounting grooves along the length direction. By providing weight-reducing through holes along the length direction in each support rod, the cargo box structure can be further made lighter. At the same time, by providing limiting mounting grooves along the length direction on the opposite side surfaces of each support rod, it is convenient to fix and facilitates the height adjustment of the second pull-out panel assembly.

[0010] According to some embodiments of this application, the side panel fixing assembly includes a third support rod, a first connecting plate, and a second connecting plate. The second connecting plate is fixedly connected to the side end face of the first connecting plate, and the third support rod is fixedly connected to one side surface of the second connecting plate. By setting the side panel fixing assembly, it is convenient to achieve the function of supporting and fixing the second pull-out panel assembly.

[0011] According to some embodiments of this application, the third support rod is provided along the connection between the first connecting plate and the second connecting plate. The first connecting plate is provided with a fourth mounting hole in the vertical direction, and the second connecting plate is provided with a fifth mounting hole at intervals in the length direction. The fourth and fifth mounting holes facilitate the fixed installation of the side panel fixing assembly on the inner surface of the open carriage side panel, making installation and disassembly convenient.

[0012] According to some embodiments of this application, the longitudinal section structure of the third support rod is the same as that of the first support rod and the second support rod. The first support rod, the second support rod and the third support rod are parallel to each other. By making the first support rod, the second support rod and the third support rod parallel to each other, the structure of the cargo box device is more compact, and at the same time, it can support and fix the second pull-out panel assembly.

[0013] According to some embodiments of this application, the first pull-out panel assembly includes a first placement panel, a first bottom support plate, and a stop plate. The stop plate is fixedly connected to one side end face of the first bottom support plate, and the first bottom support plate is fixedly installed on the top surface of the guide support plate. The bottom surface of the first placement panel is slidably connected to the top surface of the first bottom support plate. An arc-shaped portion is provided on the left end face of the first placement panel. The arc-shaped portion facilitates the pulling out of the bottom surface of the first placement panel and the placement of items. The arc-shaped portion prevents interference between the first placement panel and the inner surface of the open carriage side panel.

[0014] According to some embodiments of this application, the second pull-out panel assembly includes a second placement panel, a second bottom support plate, and an adjustment support assembly. The second placement panel is slidably connected to the second bottom support plate. The adjustment support assembly is fixedly arranged at intervals along the width direction on the bottom surface of the second bottom support plate. The two ends of the adjustment support assembly are detachably connected to the side surfaces of the first support rod and the second support rod, respectively. The second pull-out panel assembly facilitates the placement and retrieval of items, while also increasing space utilization.

[0015] Secondly, this application provides a vehicle, which includes an open cargo compartment and a cargo box structure assembly fixedly installed in the open cargo compartment. The cargo box structure assembly is a lightweight, detachable cargo box structure for vehicle-mounted crossing as described in any one of the first aspect embodiments above.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0025] Among existing pickup truck models, high-end luxury pickups are trending towards the functionality of mid-to-high-end sedans and multi-purpose vehicles. The open cargo bed of pickups is also increasingly featuring functional designs, and the installation of a cargo box is one of the main improvements in pickup trucks. The cargo box can be used to store clothes, rescue tools, tents, food and water. During self-driving tours and long-distance driving, the installation of the cargo box meets the user's need to carry more items. The inventors discovered that existing cargo box mods are mostly retrofitted and installed on open truck beds. While their design prioritizes storage and functionality, they are unsuitable for short off-road self-driving tours. The large size and weight of these mods result in high wind resistance during vehicle movement, leading to a poor off-road driving experience. Furthermore, they are not designed to fully integrate with the internal structure of the pickup truck bed, making assembly and disassembly cumbersome and time-consuming. Additionally, the structural stability of these mods is poor during long-term driving on bumpy roads, causing them to loosen and make noise.

[0026] Based on this, the inventors, through in-depth research, designed a novel lightweight, detachable cargo box structure for off-road driving. This cargo box structure has distinct layers, meeting users' needs for off-road driving while being lightweight and compact. By combining the various components of the cargo box device in a modular design, it facilitates the installation and disassembly of the cargo box device. At the same time, the structure of the cargo box device is designed in full integration with the internal structure of the pickup truck bed, improving the structural stability of the cargo box device after installation and preventing loosening and noise at the connection points. This enhances the user experience when driving the vehicle on off-road self-driving tours.

[0027] The lightweight, detachable off-road cargo box structure disclosed in this application is installed in the open rear cargo bed of a pickup truck and is used to partition and store various types of off-road equipment and items. The lightweight, detachable off-road cargo box structure provided in this application will be described below.

[0028] For ease of description in the following embodiments, an XYZ three-axis Cartesian coordinate system is established. The length direction of the cargo box device 10 is defined as the X-axis, the width direction as the Y-axis, and the height direction as the Z-axis. It should be understood that the X-axis includes both positive and negative directions, and the Y-axis and Z-axis are defined similarly. The coordinate system of the cargo box device 10 can be flexibly set according to actual needs. This application only provides one example and should not be considered a specific limitation imposed on this application.

[0029] Please see Figures 1 to 2 , Figure 1 This application shows a schematic diagram of the structure of the open rear cargo bed of a pickup truck according to some embodiments. Figure 2This application shows a schematic diagram of a pickup truck bed structure with a lightweight, detachable cargo box structure for off-road use, provided in some embodiments. The open cargo box 100 includes a front bulkhead 110, a right side bulkhead 120, a left side bulkhead 130, a rear bulkhead 140, and a bottom bulkhead 150. The open cargo box 100 is a structure carried by the pickup truck itself on the market. The front bulkhead 110 is distributed along the Y-axis direction, and the right side bulkhead 120 and left side bulkhead 130 are respectively vertically fixed to both ends of the front bulkhead 110 along the X-axis direction. The front bulkhead 110, right side bulkhead 120, left side bulkhead 130, and bottom bulkhead 150 form an open cavity. The cargo box structure component 20 is fixedly installed in the open cavity. The bottom bulkhead 150, away from the front bulkhead 110, is rotatably connected to the rear bulkhead 140. The rear bulkhead 140 can rotate around one edge of the bottom bulkhead 150, thereby realizing the opening and closing of the open cargo box 100 to facilitate the installation of the cargo box structure component 20. Please see Figure 1 A reinforcing vertical beam 121 is provided on the inner surface of the right side panel 120 near the connection with the front panel 110. The reinforcing vertical beam 121 is provided with a limiting fixing buckle 1211 and bolt holes for fixing the cargo box structural component 20. At the same time, multiple first mounting holes 122 and second mounting holes 123 are provided along the X-axis direction on the inner surface of the right side panel 120 near the reinforcing vertical beam 121. The first mounting holes 122 and second mounting holes 123 are used to vertically fix the cargo box structural component 20, thereby further fixing the cargo box structural component 20. It can be understood that the reinforcing vertical beam 121 can be a square steel tube, and its setting further improves the structural strength of the right side panel 120. Of course, it is also understandable that the structure of the left side panel 130 is mirror symmetrical to the structure of the right side panel 120. The inner surface of the left side panel 130 is also provided with reinforcing vertical beams, limiting fixing buckles and mounting holes at the positions opposite to the right side panel 120. The fixing structures of the inner surfaces of the left side panel 130 and the right side panel 120 are symmetrically arranged to facilitate further fixing of the cargo box structure component 20. In some embodiments, the surface of the bottom panel 150 is provided with support protrusions 151 and support grooves 152 at intervals along the Y-axis direction. The length of the support protrusions 151 and support grooves 152 extends from the front panel 110 to the rear panel 140. Two third mounting holes 1521 are opened in two adjacent support grooves 152 along the Z-axis direction. Four third mounting holes 1521 form a group. Two groups of third mounting holes 1521 are spaced apart on the surface of the bottom panel 150. The arrangement of the third mounting holes 1521 facilitates the bottom fixing of the cargo box structure assembly 20. It should be noted that the support protrusion 151 and the support groove 152 are actually common surface structure treatment designs in the open cargo box 100 of pickup trucks. In the design of the cargo box structure component 20 in this embodiment, the structure of the support protrusion 151 and the support groove 152 is fully considered. Matching concave and convex parts are also provided at the bottom of the cargo box structure component 20, which engage with the support protrusion 151 and the support groove 152. This design makes full use of the unique structure of the support protrusion 151 and the support groove 152, so that after the cargo box structure component 20 is installed, its bottom fits better with the surface of the bottom panel 150, avoiding wasted space. At the same time, the concave and convex parts at the bottom of the cargo box structure component 20 are engaged with the support protrusion 151 and the support groove 152, which can prevent the lateral movement of the cargo box structure component 20 and ensure the structural stability of the cargo box structure component 20 when the vehicle is driving on bumpy roads. The cargo box structure component 20 is fixedly installed inside the open cargo box 100. The cargo box structure component 20 includes a combined frame 200, a first pull-out panel component 400 and a second pull-out panel component 500. The first pull-out panel component 400 and the second pull-out panel component 500 are stacked on the combined frame 200, and an open storage space is provided between the first pull-out panel component 400 and the second pull-out panel component 500. Optionally, a partition baffle 270 is detachably provided in the middle of the combined frame 200. A first pull-out panel assembly 400 and a second pull-out panel assembly 500 are stacked on both sides of the partition baffle 270 along the Z-axis direction. The first pull-out panel assembly 400 and the second pull-out panel assembly 500 are distributed along the X-axis direction. It can be understood that the first pull-out panel assembly 400 and the second pull-out panel assembly 500 can be pulled out from the tail panel 140. At the same time, the height of the second pull-out panel assembly 500 on both sides of the partition baffle 270 is adjustable, and the height of the second pull-out panel assembly 500 on both sides can be adjusted to different heights according to actual needs. With this design, the entire cargo box structure component 20 is smaller in size and more compact and lightweight. The first pull-out panel component 400 and the second pull-out panel component 500 can meet the user's storage needs, especially for irregularly shaped items such as shovels, jacks, medicine boxes and ropes. The items can be stored securely and are easy to retrieve, which improves the user's experience for short off-road self-driving tours. Please see Figures 3 to 5 , Figure 3 The diagram shows a structural schematic of a combo box 200 provided in some embodiments of this application. Figure 4 Some embodiments of this application are shown to provide a basis for [the application]. Figure 3 A magnified view of part A in the diagram. Figure 5The diagram shows a structural schematic of the side wall fixing assembly 250 provided in some embodiments of this application; the combined frame 200 is generally rectangular in shape, and the combined frame 200 includes a base bracket 210, a side wall fixing assembly 250, a first support rod 221, a second support rod 222, a mounting fixing plate 260, and an isolation baffle 270; the base bracket 210 includes a first crossbeam 211, a second crossbeam 212, and a guide support plate 213; A first mounting part 2112 is provided at the middle position of the first crossbeam 211 and the second crossbeam 212, and two sets of limiting protrusions 2111 are provided at intervals on the bottom surface of the first crossbeam 211 and the second crossbeam 212. There are two limiting protrusions 2111 in each set. The first crossbeam 211 and the second crossbeam 212 are distributed laterally parallel to each other along the Y-axis. The guide support plate 213 is fixedly connected to the side end face of the first crossbeam 211 and the second crossbeam 212 at both ends. Each pair of guide support plates 213 is arranged in parallel along the X-axis direction. The two sets of guide support plates 213 are respectively provided on both sides of the first mounting part 2112. The length of the first crossbeam 211 is greater than the length of the second crossbeam 212. The second mounting part 2113 is provided at both ends of the first crossbeam 211. With this configuration, the base bracket 210 is composed of a first crossbeam 211, a second crossbeam 212, and a guide support plate 213 forming a staircase shape. This makes the cargo box structure component 20 more stable and stronger after installation, preventing it from loosening during driving. At the same time, it can support heavier items. By providing two sets of limiting protrusions 2111 at intervals on the bottom surfaces of the first crossbeam 211 and the second crossbeam 212, with two protrusions in each set, each set of limiting protrusions 2111 fits precisely with the support protrusions 151 and support grooves 152 on the surface of the bottom plate 150. This makes it less likely for the cargo box structure component 20 to wobble from side to side after installation, making the cargo box structure component 20 more secure.

[0030] In some embodiments, a second support rod 222 is fixedly installed on the first mounting portion 2112 of the first crossbeam 211 and the second crossbeam 212 along the Z-axis direction. The second support rod 222 is perpendicular to the first crossbeam 211 and the second crossbeam 212 in the vertical direction. At the connection between the second support rod 222 and the first crossbeam 211 and the second crossbeam 212, L-shaped fixing plates 230 are fixedly installed at both ends. The longitudinal section of the L-shaped fixing plate 230 is a right angle. When connected, one end of the L-shaped fixing plate 230 is fixedly connected to the side surface of the second support rod 222, and the other end is fixedly connected to the side surface of the first crossbeam 211 and the second crossbeam 212. A first support rod 221 is fixedly installed at each of the two ends of the first crossbeam 211 by a second mounting part 2113. It can be understood that the first support rod 221 and the second support rod 222 are parallel in the Z-axis direction. The height of the first support rod 221 is less than that of the second support rod 222. At the same time, the first support rod 221 and the second support rod 222 have the same material structure and the same cross-sectional shape. Weight-reducing through holes are opened in the first support rod 221 and the second support rod 222 along the length direction. Preferably, the height of the first support rod 221 is equal to or less than the height of the side panel. An L-shaped fixing plate 230 is fixedly installed at a right angle at the connection between the first support rod 221 and the first crossbeam 211. The two sides of the L-shaped fixing plate 230 are respectively attached to the surfaces of the first support rod 221 and the first crossbeam 211.

[0031] This design improves the structural strength and stability of the cargo box structure component 20, while also expanding the longitudinal storage space of the cargo box structure component 20. The length of the first support rod 221 on both sides is shorter than the length of the second support rod 222, which facilitates installation and ensures the aesthetics of the cargo box structure component 20 after installation.

[0032] Please see Figure 4 The first support rod 221 and the second support rod 222 have vertically oriented limiting mounting grooves 2221 on their opposite sides. The longitudinal section of the limiting mounting grooves 2221 is concave. The second pull-out panel assemblies 500 installed on both sides of the first support rod 221 and the second support rod 222 are connected and fixed through the limiting mounting grooves 2221. Weight reduction through holes are opened along the length direction on both sides of the limiting mounting grooves 2221 of the first support rod 221 and the second support rod 222, thereby further reducing the mass of the cargo box structure assembly 20. Meanwhile, the limiting installation groove 2221 can also be used to adjust the height of the storage box 300 in the Z-axis direction. In order to make the structure of the storage box 300 more robust after installation, a fixed sheet metal part 240 is fixedly connected to the top two sides of the second support rod 222. The fixed sheet metal part 240 is inverted L-shaped after installation. The fixed sheet metal part 240 is embedded into the limiting installation groove 2221 by the nut of the fixing bolt 241 and then fixed by bolts. In some embodiments, a fixed sheet metal part 240 is fixedly connected to the top two sides of the two second support rods 222. The fixed sheet metal part 240 can be moved up and down in the Z-axis direction along the limiting mounting groove 2221 to adjust its position. After the height is adjusted, it is fixed by the fixing bolt 241. Its storage box 300 is installed below the fixed sheet metal part 240. The bottom of the storage box 300 is provided with a mounting support plate 350 for support. Both ends of the mounting support plate 350 are detachably connected to the support rods.

[0033] Please see Figure 3and Figure 5 Mounting plates 260 are adjustablely and fixedly connected to the surfaces of the two first support rods 221 near the right side panel 120 and the left side panel 130. The mounting plates 260 can be adjusted up and down along the height direction of the first support rods 221. The side of the mounting plate 260 away from the first support rods 221 is fixedly connected to the inner surface of the right side panel 120 and the left side panel 130 by bolts. The surface shape of the side of the mounting plate 260 connected to the side panel fits the surface shape of the side panel, thereby restricting the degree of freedom of the cargo box structure component 20 in the X-axis direction and preventing the cargo box structure component 20 from moving back and forth.

[0034] In some embodiments, a side panel fixing assembly 250 is also fixedly connected to the inner surfaces of the right side panel 120 and the left side panel 130, which are at the same height as the mounting fixing plate 260. The side panel fixing assembly 250 is used in conjunction with the first support rod 211 and the second support rod 222. The side panel fixing assembly 250 includes a third support rod 251, a first connecting plate 252 and a second connecting plate 253. The third support rod 251 has a weight-reducing through hole along its length. The second connecting plate 253 is fixedly disposed on the side end face of the first connecting plate 252. The surface of the first connecting plate 252 has a fourth mounting hole 2521 and the surface of the second connecting plate 253 has a fifth mounting hole 2531. The side panel fixing assembly 250 is installed and fixed to the surface of the car side panel through the fourth mounting hole 2521 and the fifth mounting hole 2531. The third support rod 251 is fixedly connected to the inner surface of the second connecting plate 253 by bolts. The third support rod 251 is distributed along the Z-axis direction. Limiting installation grooves are also provided on both sides of the third support rod 251 along the height direction. The height of the top of the third support rod 251 in the Z-axis direction is equal to the height of the top of the first support rod 221 in the Z-axis direction. It is understandable that, similar to the first support rod 221, side wall fixing components 250 are fixedly installed on the inner surfaces of the right side panel 120 and the left side panel 130, and the two side wall fixing components 250 and the first support rod 221 are arranged in a mirror symmetrical manner with respect to the isolation baffle 270. With this configuration, the side panel fixing component 250 provides support points, facilitating the fixed installation of the storage box 300. At the same time, when used in conjunction with the mounting fixing plate 260, since the inner surfaces of the right side panel 120 and the left side panel 130 are not complete planes, the shape and structure of the side panel fixing component 250 and the mounting fixing plate 260 are designed to fit the side panels, thereby ensuring the stability of the connection and making the structure of the cargo box component 20 more stable after installation. Please see Figure 6 , Figure 6The diagram shows a structural schematic of a first pull-out panel assembly 400 provided in some embodiments of this application. The first pull-out panel assembly 400 includes a first placement panel 410, a first bottom support plate 420, and a stop plate 421. The stop plate 421 is fixedly connected to the width direction end face of the first bottom support plate 420. The first bottom support plate 420 is fixedly installed on the guide support plate 213. The first placement panel 410 is slidably connected to the top surface of the first bottom support plate 420. It should be noted that the sliding connection can be achieved by using a small pulley and a slide rail. For example, the slide rail is fixedly set on the upper surface of the first bottom support plate 420, and the small pulley is fixedly installed on the bottom surface of the first placement panel 410. In this way, the small pulley and the slide rail cooperate with each other, and the small pulley can roll along the slide rail to achieve the sliding connection. In some embodiments, an arc-shaped portion 411 is provided on the left end face of the first placement panel 410. The arc-shaped portion 411 can avoid the wheel position structure inside the open carriage 100, avoid interference between the first placement panel 410 and the bottom surface of the open carriage 100, and at the same time make full use of the interior space of the open carriage 100. A handle 412 is provided on one end face of the first placement panel 410 near the stop plate 421. The handle 412 makes it convenient for the user to pull out the first placement panel 410. Please see Figure 7 , Figure 7 A schematic diagram of the structure of a second pull-out panel assembly 500 provided in some embodiments of this application is shown. The second pull-out panel assembly 500 includes a second placement panel 510, a second bottom support plate 520, and an adjustment support assembly 530. The second placement panel 510 is slidably connected to the second bottom support plate 520. Adjustment support assemblies 530 are fixedly provided at intervals along the width direction on the bottom surface of the second bottom support plate 520. The two ends of the adjustment support assemblies 530 are detachably and fixedly connected to the first support rod 221 and the second support rod 222, respectively.

[0035] It should be noted that the sliding connection between the second placement panel 510 and the second bottom support plate 520 can be achieved by a small pulley and a slide rail. For example, the slide rail is fixedly set on the upper surface of the second bottom support plate 520, and the small pulley is fixedly installed on the bottom surface of the second placement panel 510. In this way, the small pulley and the slide rail cooperate with each other, and the small pulley can roll along the slide rail to achieve the sliding connection. In some embodiments, the adjustable support assembly 530 includes a support strip 531, a connecting block 532, and an adjustable fixing block 533. The two ends of the support strip 531 are respectively vertically connected to the connecting block 532. An adjustable fixing block 533 is installed on the surface of the connecting block 532 away from the support strip 531. The adjustable fixing block 533 is engaged with the limiting mounting groove 2221. Thus, the height of the adjustable support assembly 530 can be adjusted by adjusting the fixing block 533 and the limiting mounting groove 2221. Please see Figures 9 to 10 This embodiment provides an alternative structure for the second pull-out panel assembly 500, which achieves the same technical effect as the cargo box structure assembly in the above embodiment. Figure 9 The present application shows a schematic diagram of the structure of a storage box provided in some embodiments. Figure 10 Some embodiments of this application are shown to provide a basis for [the application]. Figure 9 The enlarged schematic diagram of part B shows that the storage box 300 has an opening on the leftmost end face in the Y-axis direction. The storage box 300 has a storage chamber 320 extending inward from the box opening 310 along the Y-axis direction. A partition 330 is provided in the middle of the storage chamber 320. The surface where the box opening 310 is located is inclined upward. A box cover 311 is snapped to the box opening 310. This improves the aesthetics of the cargo box structure component 20 and reduces the longitudinal section of the storage box 300, thus reducing wind resistance.

[0036] In some embodiments, a mounting support plate 350 is fixedly connected to the bottom of the storage box 300. The mounting support plate 350 is arranged along the Y-axis direction, and two mounting support plates 350 are arranged parallel and spaced apart at the bottom of the storage box 300. Each of the mounting support plates 350 is fixedly connected to both ends of a connecting plate 360. The connecting plate 360 ​​is arranged perpendicular to the mounting support plate 350. The surface of the connecting plate 360 ​​is provided with a limiting sliding hole 361 along the X-axis direction. It can be understood that the two limiting sliding holes 361 in the figure are arranged horizontally spaced apart on the surface of the connecting plate 360. The limiting sliding hole 361 can also be one or three, depending on the actual needs. A T-shaped connecting block 362 is fixedly connected at the limiting sliding hole 361. The T-shaped connecting block 362 is fixed in the limiting sliding hole 361 by a connecting bolt 363.

[0037] This design improves the structural strength of the storage box 300. At the same time, the connecting plate 360 ​​facilitates the vertical height adjustment of the storage box 300. If it is necessary to adjust the space below the storage box 300, the tightness of the T-shaped connecting block 362 can be changed by adjusting the connecting bolt 363. The T-shaped connecting block 362 is embedded in the limiting mounting groove 2221, thereby enabling the storage box 300 to slide vertically along a preset trajectory.

[0038] In some embodiments, a vehicle is also provided, the vehicle including an open cargo compartment 100 and a cargo box structure assembly 20, the cargo box structure assembly 20 being installed inside the open cargo compartment 100, the beneficial effects of which are as described in the above embodiments and will not be repeated here.
