Description

Technical Field

[0001] This utility model relates to the field of automobile cargo boxes, specifically to a cargo box side panel raising device. Background Technology

[0002] The cargo box includes a floor, side panels rotatably connected to both sides of the floor, and a rear panel rotatably connected to the rear end of the floor. A front panel is fixedly connected to the front end of the floor. The front panel, side panels, and rear panel together with the floor form the cargo box. In order to achieve lightweighting during vehicle manufacturing, the side panel body and the rear panel body are both made by bending metal sheets. Therefore, side pillars are fixedly installed at both ends of the side panel body, and rear pillars are fixedly installed at both ends of the rear panel body. The pillars support and protect the rear panel and side panel from deformation. The side panels and rear panel are hinged to the cargo box floor, and the side panels and rear panel are connected by locking hooks and locking buckles.

[0003] Standard cargo boxes are not tall enough when loading lightweight and bulky goods, resulting in low space utilization. However, existing cargo box heightening devices are fixed to the cargo box, and users cannot flexibly change them according to actual conditions. Based on the above technical problems, the following improvements are proposed. Utility Model Content

[0004] The present invention aims to provide a cargo box side panel raising device to solve the problem of poor flexibility of cargo box raising devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cargo box side panel raising device, comprising a side panel rotatably disposed at the top of the side panel, and a tail panel vertically slidably connected to the rear panel. A first positioning component and a second positioning component are provided between the side panel and the side panel. The side panel can be rotated to be tangent to the outer side of the side panel and fixed by the first positioning component. The side panel can also be rotated to be coplanar with the inner side of the side panel at the top and fixed by the second positioning component. A third positioning component is provided between the tail panel and the side panel. The tail panel slides vertically upward and is fixedly connected to the side panels on both sides by the third positioning component.

[0006] The beneficial effects of this solution are as follows: When only the sides of the cargo box need to be raised, the side panels are rotatably connected to the side rails, rotating the side panels to be vertical and coplanar with the side rails, and then fixed by the second positioning component; when both sides and the rear of the cargo box need to be raised, the tail panel slides up from the rear rails and is fixedly connected by the third positioning component. Through the hinge-type raising and the slider rail telescopic raising structure, users can flexibly switch between raising or not raising the cargo box according to the usage scenario; in addition, this design makes loading and unloading goods more convenient. When loading and unloading goods, the tail panel can be lowered first, and the goods can be unloaded from the rear of the cargo box.

[0007] Preferably, as an improvement, the length of the side panel is the same as the length of the side rail panel, and the length of the tail panel is the same as the length of the rear rail panel.

[0008] Preferably, as an improvement, a guide rail is vertically installed on the inner side of the rear panel, and a slider is fixedly installed on the outer side of the tail panel, with the slider slidably connected to the guide rail.

[0009] The beneficial effects are as follows: the structure, with the guide rail vertically fixed to the inner side of the rear panel and the slider connected to the outer side of the tail panel, forms a precise vertical guiding constraint, effectively limiting the lateral offset and swaying of the tail panel during lifting. Compared to traditional structures without guidance, this design avoids jamming and stagnation caused by rear panel offset. Especially when loading heavy objects (such as goods or equipment) or in windy outdoor environments, it ensures that the rear panel always runs smoothly along the preset trajectory, reducing the risk of goods falling or equipment collisions caused by structural swaying, and significantly improving the safety and reliability during operation.

[0010] Preferably, as an improvement, the first positioning component includes a first pin disposed at both ends of the side plate and a first socket disposed at both ends of the side rail plate, with the first pin and the first socket corresponding to each other.

[0011] The beneficial effects are as follows: when the side of the cargo box does not need to be raised, the side plate is rotated to be vertical and tangent to the side rail, and at the same time the first pin on the side plate is inserted into the first socket, thereby fixing the side plate and preventing the side plate from colliding with the side rail due to shaking during the operation of the vehicle body, thus generating noise.

[0012] Preferably, as an improvement, the second positioning component includes a plurality of first locking hooks disposed at the top of the side panel and a plurality of first locking buckles disposed at the bottom of the side panel, wherein the first locking buckles and the first locking hooks correspond one to one.

[0013] The beneficial effect is that when the side panel is rotated to a vertical position and is coplanar with the inner side of the side panel, the first locking hook on the side panel is engaged with the first locking buckle on the side panel, thereby unilaterally fixing the side panel in the vertical position of the side panel. At this time, it can meet the condition when the cargo box only needs to be raised on the side.

[0014] Preferably, as an improvement, the third positioning component includes a second locking hook and a second pin disposed at both ends of the tail plate, and a second latch and a second socket disposed at both ends of the side plate, wherein the second locking hook and the second latch correspond to each other, and the second latch and the second socket correspond to each other.

[0015] The beneficial effects are: it facilitates fixing the raised tail panel, and the raised tail panel is fixedly connected to the raised side panel, thereby raising both sides and the rear of the cargo box.

[0016] Preferably, as an improvement, a third socket is provided at both ends of the inner side of the rear panel, and the third socket is for the insertion of the second pin.

[0017] The beneficial effect is that by setting a third socket, when the tailgate is in its initial state on the rear panel, the second pin slides vertically downward with the tailgate and corresponds to the third socket. The second pin is inserted into the third socket, thereby fixing the tailgate in its initial state to the rear panel, thus ensuring that the tailgate in its initial state will not collide with the rear panel and generate noise as the vehicle moves.

[0018] Preferably, as an improvement, the slider is located at the bottom of the tail plate, and a first limiting block is provided at the connection between the guide rail and the base plate. The height of the first limiting block is not less than the distance between the slider and the bottom of the tail plate.

[0019] The beneficial effects are as follows: when the tail plate is in the initial state, the bottom end of the slider abuts against the top end of the first limiting block, and the height setting of the first limiting block can ensure that the bottom end of the tail plate does not collide with the base plate when the tail plate falls.

[0020] Preferably, as an improvement, a second limiting block is provided at the top of the guide rail.

[0021] The beneficial effects are: it can prevent the slider from falling off the guide rail and ensure the stability of the tail plate sliding connection. Attached Figure Description

[0024] Example The basic implementation examples are as follows: Figures 1-6 As shown, Figures 1-3 The above-displayed cargo box side panel raising device includes a side plate 2 rotatably connected to a side panel 12. A hinge 122 is fixedly installed on the outer side of the top of the side panel 12. The outer side of the top of the side panel 12 and the horizontal surface of the bottom of the side plate 2 are respectively welded to two blades of the hinge 122. In addition, the rotating seat of the hinge 122 is also fixedly welded to the side of the top of the side panel 12. Several hinges 122 are provided. The side columns 123 at both ends of the side panel 12 are each welded and fixed with a first socket 1231. The first sockets 1231 at both ends are symmetrically arranged. The inner sides of the side plate 2 are each welded and fixed with a first pin 23. The first pin 23 is a spring pin. The first pin 23 and the first socket 1231 together form a first positioning component. When the side plate 2 is rotated to a naturally drooping state, the outer side of the side plate 2 is tangent to the inner side of the side panel 12. At this time, the first pin 23 is inserted into the first socket 1231 to fix the two.

[0025] like Figure 2 As shown, several first locking hooks 121 are bolted at equal intervals to the top of the inner side of the side rail 12, and several first locking buckles 21 are bolted at equal intervals to the bottom of the inner side of the side plate 2. The several first locking buckles 21 correspond one-to-one with the several first locking hooks 121. The first locking hooks 121 and the first locking buckles 21 together form the second positioning component. When the side plate 2 is rotated to the vertical upward position, the bottom surface of the side plate 2 sits on the top surface of the side rail 12, and the inner surface of the side plate 2 is coplanar with the inner surface of the side rail 12. At this time, the several first locking hooks 121 are engaged with the first locking buckles 21, thereby fixing the vertical state of the side plate 2, thereby increasing the height of the side rail 12.

[0026] like Figures 5-6 As shown, several vertically parallel guide rails 131 are fixedly welded to the inner side of the rear panel 13. The bottom and top ends of the guide rails 131 are respectively fixedly welded to the first limiting block 1311 and the second limiting block 1312. Several sliders 31 are fixedly welded to the outer side of the tail plate 3. The sliders 31 correspond one-to-one with the guide rails 131 and are all slidably connected to the guide rails 131. The two ends of the inner side of the tail plate 3 are bolted to the second locking hooks 32. The tail plate 3 is welded to the second pin 33 below the second locking hooks 32. The second pin 33 is also set as a spring pin. The two ends of the inner side of the side plate 2 are bolted to the second latches 22. The side plate 2 is fixedly welded to the second socket 24 below the second latches 22. The second locking hooks 32 correspond to the second latches 22, and the second pins 33 correspond to the second sockets 24. The second locking hooks 32, the second latches 22, the second pins 33, and the second sockets 24 together form the third positioning component.

[0027] When the tail plate 3 is raised vertically, the slider 31 collides with the second limiting block 1312. At this time, the second pin 33 is first inserted into the second socket 24 to fix the vertical height of the tail plate 3. Then, the second locking hook 32 is engaged with the second locking buckle 22 to fix the tail plate 3 to the side plate 2. The rear columns 132 at both ends of the rear rail plate 13 are fixedly welded with a third socket 1321 for the second pin 33 to be inserted. In addition, the slider 31 is welded to the bottom of the tail plate 3, and the height of the limiting block is not less than the distance between the bottom of the slider 31 and the bottom of the tail plate 3.
