Description

Technical Field

[0001] This application relates to the field of automotive cargo box technology, and in particular to a stackable modular cargo box device and vehicle for vehicle-mounted camping. Background Technology

[0002] A pickup truck is a vehicle type that uses a car-like front end and cab while 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 outdoor camping. To meet these camping needs, especially with the rapid rise in the consumption of high-end luxury pickups, there is a trend towards their functionality shifting towards mid-to-high-end sedans and multi-purpose vehicles. To leverage 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 the direct installation of camping boxes and tents in the open cargo compartment. These camping boxes are equipped with cabinets, water tanks, and bed boards, which can meet most of the needs of camping users. However, due to the complex setup of the camping boxes to meet more integrated functions, they are expensive, bulky, and have an unattractive appearance. They are also cumbersome to use, and the space utilization rate of the open cargo compartment in the rear of the pickup truck is low. Summary of the Invention

[0004] This application aims to propose a stackable modular cargo box device and vehicle for vehicle-mounted camping, in order to solve the problems of high price, excessive size and unsightly appearance of camping boxes mounted on the rear of pickup trucks, cumbersome use, and low space utilization of the open rear cargo box of pickup trucks in the prior art.

[0005] To achieve the above objectives, in a first aspect, embodiments of this application provide a vehicle-mounted camping stackable cargo box device, comprising: A combined frame, the combined frame including a base bracket, a first support rod fixedly connected to both ends of the base bracket, and a second support rod fixedly connected to the top surface of the middle of the combined frame; At least one double-layer pull-out cabinet is fixedly installed on the top surface of the base bracket. The double-layer pull-out cabinet includes a side support plate, a bottom support plate, a pull-out storage cabinet, and a pull-out placement panel. The pull-out storage cabinet is slidably connected to the top surface of the bottom support plate, and the pull-out placement panel is slidably connected to the top surface of the pull-out storage cabinet. The side support plate is vertically fixedly connected to the bottom support plate, wherein the inner surface of the side support plate is in contact with the side surface of the pull-out storage cabinet. At least one storage box is fixedly installed on the top of the combined frame. The storage box and the double-layer pull-out box are coaxial in the vertical direction. The storage box is rectangular in shape. The four corners of the bottom of the storage box are detachably connected to the side surfaces of the first support rod and the second support rod, respectively. The storage box has a storage chamber opened inward from the side end face along the width direction.

[0006] The combined frame is fixedly installed inside the open rear cargo bed of a pickup truck. At the bottom of the combined frame is a double-row, double-layer pull-out cargo box, which includes pull-out storage cabinets and pull-out placement panels. Both the cabinets and panels can be pulled out and slid along their length. The storage cabinets can be used to store food, clothing, and some external medicines, while the area above the placement panels can be used to store cooking utensils, kitchenware, and rescue tools. A storage box is located above the double-layer pull-out cargo box, with a horizontally extending storage compartment on its side. This compartment contains partitions, allowing for the storage of more items. The storage box's height can be adjusted vertically along a support rod, allowing for adjustment of the space above the placement panels for greater user convenience. The overall structure of the cargo box is compact and space-efficient, designed with the dimensions of the open rear cargo bed in mind, resulting in an aesthetically pleasing and user-friendly design. According to some embodiments of this application, the double-layer pull-out box is disposed between the first support rod and the second support rod, and the lengths of the first support rod and the second support rod are greater than the height of the double-layer pull-out box. By vertically disposing the double-layer pull-out box between the first support rod and the second support rod, the space utilization rate of the cargo box device in the open rear cargo compartment of pickup trucks is improved. Furthermore, the fact that the lengths of the first support rod and the second support rod are greater than the height of the double-layer pull-out box facilitates the installation of the storage box.

[0007] According to some embodiments of this application, the double-layer pull-out box further includes a mounting limiting plate, which is vertically fixed to the top surface of the side support plate. The mounting limiting plate has the same length as the pull-out placement panel, and the top surface of the mounting limiting plate is coplanar with the top surface of the pull-out placement panel. The mounting limiting plate facilitates the fixing of the double-layer pull-out box. At the same time, the coplanar arrangement of the top surface of the mounting limiting plate and the top surface of the pull-out placement panel increases the storage space on the top surface of the pull-out placement panel, thereby improving the space utilization rate of the cargo box device.

[0008] According to some embodiments of this application, a first clearance notch and a second clearance notch are provided at intervals on one end face of the mounting limiting plate away from the pull-out placement panel. The first clearance notch and the second clearance notch are respectively attached to the outer surface of the support rod. By setting the first clearance notch and the second clearance notch, the first clearance notch and the second clearance notch are respectively semi-enclosed and attached to the outer surface of the support rod. In this way, the degree of freedom of the double-layer pull-out box is restricted, making the double-layer pull-out box more stable after installation.

[0009] According to some embodiments of this application, the surfaces of the first support rod and the second support rod are provided with limiting installation grooves along the height direction. The longitudinal section structure of the first support rod and the second support rod is the same. The limiting installation grooves are provided on the opposite side surfaces of the first support rod and the second support rod. The limiting installation grooves are used for connecting and fixing the storage box. At the same time, when it is necessary to adjust the height of the storage box, the storage box can be adjusted vertically along the limiting installation grooves and then fixed.

[0010] According to some embodiments of this application, the storage box further includes a mounting support plate and a connecting plate. The mounting support plate is fixedly connected to the bottom surface of the storage box at intervals and parallel. The connecting plate is fixedly connected to both ends of the mounting support plate. The connecting plate is fixedly connected to the support rod. The connecting plate is perpendicular to the mounting support plate. The side surface of the connecting plate away from the mounting support plate abuts against the surfaces of the first support rod and the second support rod, respectively. The mounting support plate makes the storage box structure more robust. The connecting plate facilitates fixing the storage box and adjusting its vertical position.

[0011] According to some embodiments of this application, each of the connecting plates far from the mounting support plate has a plurality of limiting sliding holes on its surface. The limiting sliding holes are fixedly connected to T-shaped connecting blocks by connecting bolts. The T-shaped connecting blocks cooperate with the limiting mounting groove to connect and fix the storage box. By setting the T-shaped connecting blocks, the T-shaped connecting blocks are embedded in the limiting mounting groove. The T-shaped connecting blocks can move vertically along the opening of the limiting mounting groove, thereby cooperating with the limiting mounting groove to adjust the position of the storage box and connect and fix it.

[0012] According to some embodiments of this application, two storage boxes are arranged opposite to each other on both sides of the second support rod, wherein the openings of the storage chambers of the two storage boxes are away from the second support rod, and each storage chamber is provided with a partition along the width direction. By setting two storage boxes on both sides of the second support rod, the storage capacity of the cargo box device is increased, and at the same time, the structure of the cargo box device is made more compact.

[0013] According to some embodiments of this application, the height of the first support rod is less than the height of the second support rod, and the second support rod has fixed sheet metal parts fixedly installed on its two sides near the top. The fixed sheet metal parts facilitate the fixing of the top surface of the storage box. By making the height of the first support rod less than the height of the second support rod, the weight of the cargo box device is reduced, and the production cost is also reduced.

[0014] Secondly, embodiments of this application provide a vehicle, the vehicle including an open cargo compartment and a cargo box device fixedly installed in the open cargo compartment, the cargo box device being a vehicle-mounted camping stacked modular cargo box device as described in any of the embodiments of the first aspect above.

[0015] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0023] 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.

[0024] Among existing pickup truck models, high-end luxury pickups are trending towards mid-to-high-end sedans and multi-purpose vehicles in terms of vehicle functions. More and more open cargo beds are being designed with additional functions, and equipping them with cargo boxes is one of the main improvements in pickup trucks. Cargo boxes can be used to store clothing, rescue tools, tents, food, and water. During self-driving tours and long-distance driving, the addition of cargo boxes meets the needs of users to carry more items. The inventors discovered that existing cargo box devices integrate a large number of functions, but there is no reasonable space optimization design between the various functional areas of the cargo box. At the same time, they do not fully integrate with the open cargo box structure of pickup trucks, resulting in complex structure, high price, excessive size and unsightly appearance. They are also cumbersome to use and have low utilization rate of the open cargo box space of pickup trucks.

[0025] Based on this, the inventors conducted in-depth research and designed a stackable cargo box device for vehicle camping. The cargo box device has a clear layered structure, which can accommodate the separate placement of clothing, rescue tools (shovels, tow ropes, shackles, escape boards and jacks, etc.), tents, food and water resources. It optimizes the internal space of the device, making it smaller and lighter, further reducing its production cost. At the same time, it provides a better user experience and a more aesthetically pleasing appearance. This application discloses a vehicle-mounted camping stackable cargo box device, which is installed in the open rear cargo compartment of a pickup truck and is used to store various types of items in separate areas. The following is a description of the vehicle-mounted camping stackable cargo box device provided by this application.

[0026] 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 the 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 an example and should not be considered as a special limitation on this application.

[0027] Please see Figures 1 to 3 , Figure 1 This application provides schematic diagrams of pickup truck body structures for assembling stacked modular cargo box devices for vehicle camping, according to some embodiments of the present application. Figure 2 This application shows a schematic diagram of the structure of the open rear cargo bed of a pickup truck according to some embodiments. Figure 3 The diagram shows a structural schematic of a stackable cargo box device for pickup truck camping provided in some embodiments of this application. The open cargo box 100 includes a front panel 110, a right side panel 120, a left side panel 130, a rear panel 140, and a bottom panel 150. The front panel 110 is distributed along the Y-axis direction, and the right side panel 120 and the left side panel 130 are respectively vertically fixed to the two ends of the front panel 110 along the X-axis direction. The front panel 110, the right side panel 120, the left side panel 130, and the bottom panel 150 form an open cavity. The cargo box device 20 is fixedly installed in the open cavity. The bottom panel 150, away from the front panel 110, is rotatably connected to the rear panel 140. The rear panel 140 can rotate around one edge of the bottom panel 150 to open and close, so as to facilitate the installation of the cargo box device 20. Please see Figure 2A 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 device 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 device 20, thereby further fixing the cargo box device 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 that 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 those of 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 device 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 device 20. It should be noted that the support protrusion 151 and 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 device 20 in this embodiment, the structure of the support protrusion 151 and support groove 152 is fully considered. Matching concave and convex parts are also provided at the bottom of the cargo box device 20, which engage with the support protrusion 151 and 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 device 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 device 20 are engaged with the support protrusion 151 and the support groove 152, which can prevent the lateral movement of the cargo box device 20 and ensure the structural stability of the cargo box device 20 when the vehicle is driving on bumpy roads. Please see Figure 3 as well as Figure 4 , Figure 4The diagram shows a structural schematic of a combined frame 200 provided in some embodiments of this application; the cargo box device 20 is rectangular in shape, and the combined frame 200 is three-dimensional. The combined frame 200 includes a base bracket 210, a side wall fixing component 250, a first support rod 221, a second support rod 222, a connecting 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 on the middle top surface 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. Each set of limiting protrusions 2111 consists of two protrusions. 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 faces of the first crossbeam 211 and the second crossbeam 212 at both ends. Each set of two guide support plates 213 is arranged in parallel along the X-axis. 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. A 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 structure of the cargo box device 20 more stable and stronger after installation, preventing the cargo box device 20 from loosening during travel. 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 device 20 to sway left and right after installation, making the cargo box device 20 more secure after installation.

[0028] 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 second mounting portions 2113 provided at both ends of the first crossbeam 211. 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. 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.

[0029] This design improves the structural strength and stability of the cargo box device 20, while also expanding the longitudinal storage space of the cargo box device 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 device 20 after installation.

[0030] Please see Figures 3 to 5 , Figure 5 It shows Figure 4 A partially enlarged schematic diagram of part A shows that the first support rod 221 and the second support rod 222 have vertically arranged limiting installation grooves 2221 on their opposite sides. The longitudinal section of the limiting installation grooves 2221 is concave. The storage boxes 300 installed on both sides of the first support rod 221 and the second support rod 222 are connected and fixed through the limiting installation grooves 2221. At the same time, the limiting installation grooves 2221 can also be used to adjust the height of the storage boxes 300 in the Z-axis direction. In order to make the structure of the storage boxes 300 more robust after installation, fixed sheet metal parts 240 are fixedly connected to the top two sides of the second support rod 222. The fixed sheet metal parts 240 are inverted L-shaped after installation. The fixed sheet metal parts 240 are embedded into the limiting installation grooves 2221 by the nuts of the fixing bolts 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.

[0031] Please see Figure 4 and Figure 6 , Figure 6The side panel fixing assembly 250 provided in some embodiments of this application is shown. A connecting fixing plate 260 is adjustablely 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 connecting fixing plate 260 can be adjusted up and down along the height direction of the first support rods 221. The side of the connecting fixing 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 connecting fixing 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 device 20 in the X-axis direction and preventing the cargo box device 20 from moving back and forth.

[0032] In some embodiments, a side wall 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 connecting fixing plate 260. The side wall fixing assembly 250 is used in conjunction with the first support rod 211 and the second support rod 222. The side wall fixing assembly 250 includes a third support rod 251, a first connecting plate 252 and a second connecting plate 253. The second connecting plate 253 is fixedly disposed on the side end face of the first connecting plate 252. A fourth mounting hole 2521 is opened on the surface of the first connecting plate 252 and a fifth mounting hole 2531 is opened on the surface of the second connecting plate 253. The side wall 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 a support point, which facilitates the fixed installation of the storage box 300. At the same time, it works in conjunction with the connecting 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 connecting 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 device 20 more stable after installation. Please see Figure 7 and Figure 8 , Figure 7 The following is a schematic diagram of the structure of the storage box 300 provided in some embodiments of this application. Figure 8 Some embodiments of this application are shown. Figure 7 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 device 20 and reduces the longitudinal section of the storage box 300, thus reducing wind resistance.

[0033] 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.

[0034] 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.

[0035] Please see Figure 3 , Figure 9 and Figure 10 , Figure 9 This application provides a schematic diagram of the structure of a double-layer pull-out box 400 according to some embodiments. Figure 10The diagram shows the structure of a double-layer pull-out cabinet 400 provided in some embodiments of this application when opened. The double-layer pull-out cabinet 400 is mounted on the surfaces of two sets of guide support plates 213 below the combined frame 300. The double-layer pull-out cabinet 400 includes a mounting limiting plate 410, a side support plate 413, a bottom support plate 414, a pull-out storage cabinet 420, and a pull-out placement panel 430. The side end face of the side support plate 413 is fixedly connected to the side end face of the bottom support plate 414, forming an L-shaped right angle with the bottom support plate 414. The pull-out storage cabinet 420 is slidably connected to the upper surface of the bottom support plate 414. It should be noted that the slidable connection can be achieved by using small pulleys and a slide rail. For example, the slide rail is fixedly installed on the upper surface of the bottom support plate 414, and the small pulley is connected to the bottom surface of the pull-out storage cabinet 420. Thus, the small pulley and the slide rail cooperate to achieve the slidable connection. The side surface of the pull-out storage cabinet 420 is attached to the side support plate 413, and the top of the pull-out storage cabinet 420 is slidably connected to the pull-out placement panel 430. It can be understood that the sliding connection between the pull-out storage cabinet 420 and the pull-out placement panel 430 can also be achieved by using small pulleys and slide rails as described above. Of course, it can also be achieved by opening slide grooves on the top of the side panels of the pull-out storage cabinet 420 and setting slide strips at the bottom of the pull-out placement panel 430. The slide strips and slide grooves cooperate to achieve the sliding connection. The pull-out storage cabinet 420 can be used to store some clothes and food-related items and has a waterproof function. In some embodiments, the bottom support plate 414 is fixedly installed on the surface of two guide support plates 213. The top of the side support plate 413 is provided with a mounting limiting plate 410 along the length direction. The side end face of the mounting limiting plate 410 is provided with a first clearance notch 411 and a second clearance notch 412. The first clearance notch 411 is provided to avoid the third support rod 251 of the side wall fixing assembly 250, and the second clearance notch 412 is provided to avoid the first support rod 221. At the same time, the mounting limiting plate 410 can provide better fixation for the double-layer pull-out box 400. Since the pull-out storage cabinet 420 and the pull-out placement panel 430 can be pulled out without interfering with each other, and an open storage space is provided between the pull-out placement panel 430 and the storage box 300, the pull-out placement panel 430 can be used to place sundries, cooking utensils, and rescue tools when the car is off-roading. In addition, the storage space above the pull-out placement panel 430 can be automatically adjusted by adjusting the height of the storage box 300, which can be applied to more scenarios. Furthermore, by setting a handle 431 on the front surface of the pull-out placement panel, the surface where the handle 431 is located is coplanar with the surface where the handle of the pull-out storage cabinet 420 is located, making it more convenient for users to store items.

[0036] In the above embodiment, the cargo box device 20 is configured such that the combined frame 200 is equipped with support rods of different lengths at each preset position of the base bracket 210. The base bracket 210, the first support rods 221 on both sides, and the side fixing components 250 are fitted and fastened to the surface of the open cargo box 100 of the pickup truck model. This ensures the structural strength of the cargo box device 20 while making the structural layout of the cargo box device 20 compact and improving the space utilization of the open cargo box 100. The storage box 300 set on the top of the cargo box device 20 opens towards the left and right side panels of the open cargo box 100. This can be used to store some items that need to be waterproof and is easy to retrieve. The openings of the storage boxes 300 on both sides are made into bevels, which helps to reduce wind resistance after installation and also increases the aesthetics of the cargo box device 20. The entire cargo box device 20 is designed with a fixed frame and a stacked box with adjustable height. It is lightweight, low-cost, and has a more stable and compact structure, making it easy to assemble and disassemble, and improving the utilization of internal space. Meanwhile, the storage box 300, pull-out storage cabinet 420 and pull-out placement panel 430 are arranged at intervals on the frame. The design of each storage compartment fully considers the items and tools that need to be stored in different scenarios, making it more applicable.

[0037] In some embodiments, a vehicle is also provided, the vehicle including an open cargo compartment 100 and a cargo box device 20, the cargo box device 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.
