Description

Technical Field

[0001] This utility model relates to the field of cargo boxes, and more specifically, to a wing-shaped cargo box structure. Background Technology

[0002] In the logistics and cargo storage sectors, cargo boxes serve as crucial load-bearing and transportation tools, and their structural design directly impacts loading and unloading efficiency, transportation safety, and ease of use. Related technologies typically employ a single-side door structure with a fixed top panel to facilitate rapid loading and unloading. However, in practical applications, it has been found that in palletized transport scenarios, after a forklift lifts the goods, the cargo box lacks sufficient lifting space. Furthermore, the side door, when open, occupies lateral space and obstructs the forklift. This results in limited utilization of the interior cargo box space and even poses a risk of collision during loading and unloading. Utility Model Content

[0003] In view of this, the present invention provides a wing cargo box structure with a larger opening space and operating space.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A flying wing cargo box structure includes a bottom plate, a top plate, a front panel, a rear panel, a left side panel, and a right side panel that can collectively form a closed cavity;

[0006] The first side of the top plate is fixedly connected or pivotally connected to the upper edge of the front panel, and the top plate is also provided with a pivot position; the cavity is provided with a first driving mechanism, which is used to drive the top plate to rotate relative to the rear panel around the pivot position;

[0007] When the second side of the top plate is pivotally connected to the front panel, a second driving mechanism is provided between the top plate and the front panel. The second driving mechanism is used to drive the front panel to rotate relative to the top plate around the second side of the top plate.

[0008] In the above technical solution, the first drive mechanism drives the top panel to rotate and flip upward relative to the rear panel, forming an open state similar to an aircraft wing. This exposes most of the side space and increases the top space of the cargo box, providing a larger, unobstructed loading and unloading opening. Simultaneously, the front panel can be opened or folded in tandem; that is, the second drive mechanism drives the front panel to flip around its connection point with the top panel, further expanding the front opening and eliminating any obstruction to loading and unloading operations. This provides a more unobstructed operating passage, especially when loading and unloading from the front of the cargo box or when using equipment such as forklifts. Therefore, this invention can significantly improve loading and unloading efficiency and convenience, and has a wider range of applications.

[0009] Optionally, in one possible implementation, the first drive mechanism includes a first support base, a second support base, and a first telescopic support member. The first support base is installed in the cavity via a first guide beam, the second support base is installed on the top plate via a second guide beam, and the two ends of the first telescopic support member are rotatably connected to the first support base and the second support base, respectively.

[0010] In the above technical solution, the first support base, the second support base, and the first telescopic support member constitute a stable triangular support structure. The thrust / tension of the telescopic support member acts directly and efficiently on the top plate through the hinge points at both ends. In addition, the hinged design at both ends allows the first telescopic support member to naturally adapt to the angle and position changes caused by the rotation of the top plate around the pivot point during the telescopic process.

[0011] Alternatively, in one possible implementation, the first support is slidably disposed on the first guide beam and fixed by a plurality of first bolts.

[0012] In the above technical solution, by sliding the first support seat along the first guide beam, the installation base point of the telescopic support member on the first guide beam can be precisely adjusted. This allows the application point of the driving force to be optimized according to the length of the cargo box, the center of gravity of the roof, or the distribution of cargo load. Under different cargo loading conditions and roof opening angle requirements, by changing the position of the first support seat on the first guide beam, the stress state of the first telescopic support member can be optimized, making the transmission of driving force more reasonable and reducing the risk of structural deformation and damage caused by uneven stress.

[0013] Alternatively, in one possible implementation, the second support is slidably mounted on the second guide beam and fixed by a number of second bolts.

[0014] In the above technical solution, the stress distribution of the top plate will change significantly under different loading conditions and opening angles. The second support seat is slidably set on the second guide beam of the top plate, and the position of the second support seat can be adjusted according to actual needs, thereby improving the support stability of the top plate.

[0015] Optionally, in one possible implementation, when the second drive mechanism is provided, the second drive mechanism includes a third support seat provided on the top plate, a fourth support seat provided on the front panel, and a second telescopic support member with its two ends respectively hinged to the third support seat and the fourth support seat.

[0016] In the above technical solution, the second drive mechanism allows the front panel to be opened independently of the top panel. Thus, the opening between the front and top panels, and between the top and rear panels, involves both linked and independent operations, making the opening method more flexible and efficient, and improving the cargo compartment's adaptability to different loading and unloading scenarios.

[0017] Alternatively, in one possible implementation, the pivot is located at the center of the top plate, and the top plate is split by the pivot into a first plate connected to the rear panel and a second plate connected to the front panel.

[0018] In the above technical solution, the pivot joint allows the top plate to be configured as a split structure. This enables users to choose the opening position of the top plate according to actual needs, without having to open the entire top plate simultaneously. This provides greater flexibility to adapt to different usage scenarios and effectively reduces the load on the first drive mechanism. It also lowers the requirements for the first drive mechanism and increases its service life.

[0019] Optionally, in one possible implementation, both the first plate and the second plate can rotate relative to the pivot position, and the first driving mechanism is provided in two symmetrically arranged sets, each set being used to drive the rotation of the first plate and the second plate, respectively.

[0020] In the above technical solution, the design of both the first and second plates being rotatable allows both the front and rear panels to be opened, meaning the truck bed can be opened from both sides. This further improves the flexibility of the truck bed and facilitates loading and unloading of goods from both sides of the truck bed by forklifts and other loading and unloading equipment, thereby improving loading and unloading efficiency.

[0021] Optionally, in one possible implementation, the enclosed cavity is further provided with a raised edge, the raised edge having a drainage groove, and the top plate and front panel covering the raised edge.

[0022] In the above technical solution, the drainage grooves on the raised edge form an orderly water flow guidance system. When it rains or the cargo compartment is being washed, the water falling on the top and front panels will flow down their surfaces and cover the raised edge. The drainage grooves can then quickly collect the water and guide it in a specific direction to drain it from the cargo compartment, thus preventing water accumulation.

[0023] Optionally, in one possible implementation, there are two or more of the first driving mechanism and the second driving mechanism.

[0024] In the above technical solution, two or more first drive mechanisms and second drive mechanisms can share the load and jointly bear the weight of the top plate and front panel as well as the external forces, which significantly improves the load-bearing capacity of the cargo box and reduces the probability of a single drive mechanism failing due to excessive force.

[0025] Optionally, in one possible implementation, the base plate is further provided with several fixing anchor rings.

[0026] In the above technical solution, the numerous anchor rings set on the base plate provide a wide variety of fixing points for goods of different shapes, sizes, and weights. Whether it is a regularly shaped box or an irregularly shaped piece of machinery or pipes, they can be connected to the anchor rings using ropes, straps, or other tools to achieve a secure binding and fixation.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. Example 1

[0039] Please refer to Figure 1 This embodiment provides a wing cargo box structure, including a bottom plate 1, a top plate 2, a front panel 3, a rear panel 4, a left side panel 5, and a right side panel 6 that can be used to form a closed cavity; the first side of the top plate 2 is fixedly connected to the upper edge of the front panel 3, and the top plate 2 is also provided with a pivot position 20, which is located on the second side of the top plate 2, that is, the side where the top plate 2 is connected to the rear panel 4; a first driving mechanism 7 is provided in the cavity, which is used to drive the top plate 2 to rotate relative to the rear panel 4 around the pivot position 20.

[0040] Specifically, in this embodiment, the base plate 1, left side plate 5, right side plate 6, and rear panel 4 are relatively fixed structures, with adjacent plates perpendicular to each other. The second side of the top plate 2 is pivotally connected to the upper edge of the rear panel 4 via multiple hinges. The front panel 3 is connected to the first side of the top plate 2, meaning the front panel 3 and the top plate 2 are perpendicular to each other. Thus, the top plate 2 and the front panel 3 are an interconnected whole. When the first drive mechanism drives the top plate 2 to flip, both the top plate 2 and the front panel 3 will open simultaneously.

[0041] In this embodiment, the first drive mechanism 7 drives the top plate 2 to rotate around the pivot 20 and flip upward, forming an open state similar to an airplane wing. This exposes most of the side space and increases the top space of the cargo box, providing a larger, unobstructed loading and unloading opening, making it more convenient for forklifts and other handling equipment to work.

[0042] Please refer to Figures 2-4 In this embodiment, the first drive mechanism 7 includes a first support base 71, a second support base 72, and a first telescopic support member 73. The first support base 71 is installed in the cavity via a first guide beam 41, and the second support base 72 is installed on the top plate 2 via a second guide beam 23. The two ends of the first telescopic support member 73 are rotatably connected to the first support base 71 and the second support base 72, respectively. In this embodiment, the first guide beam 41 can be fitted onto the rear panel 4.

[0043] The first support base 71, the second support base 72, and the first telescopic support member 73 form a stable triangular support structure. The thrust / tension of the telescopic support member acts directly and efficiently on the top plate 2 through the hinge points at both ends. In addition, the hinge design at both ends allows the first telescopic support member 73 to naturally adapt to the angle and position changes caused by the rotation of the top plate 2 around its first side during the telescopic process.

[0044] Please refer to Figure 3 or Figure 4 It should be noted that both ends of the first telescopic support 73 are hinged to the first support base 71 and the second support base 72 via ball head pins 731. One end of the ball head pin 731 is a threaded section, and the other end is a rotatable ball head. Both the first support base 71 and the second support base 72 are provided with threaded holes that mate with the threaded section. The threaded section of the ball head pin 731 is threaded into the threaded hole, and the ball head is connected to the first telescopic support 73.

[0045] The ball joint pin 731 allows the connected component to rotate in any direction around the center of the ball within a certain cone angle range. This allows the first telescopic support 73 to not only accommodate the pure rotational motion of the top plate 2 around the pivot 20, but also compensate for complex relative displacements in the cargo box under the following conditions: Furthermore, when the vehicle travels on bumpy roads or the top plate 2 is opened / remained open in strong winds, the cargo box structure is subjected to complex dynamic loads and vibrations. The ball joint pin 731 hinge effectively absorbs the instantaneous minute angular offsets caused by these dynamic loads, preventing the mechanism from jamming or generating abnormal noise, and ensuring that the opening and closing actions are always smooth and stable.

[0046] Please refer to Figure 2 and Figure 3In this embodiment, the first support base 71 is slidably disposed on the first guide beam 41 and fixed by a plurality of first bolts 711. The first guide beam 41 is vertically attached to the surface of the rear panel 4 and protrudes a certain distance relative to the surface of the rear panel 4. The first support base 71 is provided with a slot, through which the first support base 71 can be slidably engaged on the first guide beam 41. When moved to the target position, it can be locked and fixed by a plurality of first bolts 711.

[0047] By sliding the first support seat 71 along the first guide beam 41, the mounting base point of the telescopic support member on the first guide beam 41 can be precisely adjusted. This allows the application point of the driving force to be optimized according to the length of the cargo box, the center of gravity of the top plate 2, or the distribution of cargo load. Under different cargo loading conditions and the required opening angle of the top plate 2, by changing the position of the first support seat 71 on the first guide beam 41, the stress state of the first telescopic support member 73 can be optimized, making the transmission of driving force more reasonable and reducing the risk of structural deformation and damage caused by uneven stress.

[0048] In addition, please refer to Figure 1 and Figure 4 The second support 72 is slidably mounted on the second guide beam 23 and fixed by several second bolts (not shown in the figure). The second guide beam 23 is horizontally mounted on the top plate 2, that is, the second guide beam 23 is perpendicular to the first guide beam 41. The installation method of the second guide beam 21 and the second support 72 is the same as the installation method of the first guide beam 41 and the first support 71, and will not be described in detail here.

[0049] The stress distribution on the top plate 2 changes significantly under different loading conditions and opening angles. The second support seat 72 is slidably mounted on the second guide beam 23 of the top plate 2, and its position can be adjusted according to actual needs, thereby improving the support stability of the top plate 2. The first telescopic support member 73, as a key component driving the rotation of the top plate 2, directly affects the driving efficiency due to its connection position with the top plate 2. The adjustable sliding feature of the second support seat 72 allows for precise adjustment of the connection point between the first telescopic support member 73 and the top plate 2 based on factors such as the weight of the top plate 2 and the required opening angle during the design and use of the cargo box.

[0050] Please refer to Figure 5In this embodiment, a raised edge 9 is also provided inside the enclosed cavity. The raised edge 9 has a drainage groove 91, and the top plate 2 and the front panel 3 cover the raised edge 9. Specifically, the raised edge 9 is distributed on the left side plate 5, the right side plate 6, and the rear panel 4 at positions that contact the top plate 2 or the front panel 3 when closed. That is, the top plate 2 and the front panel 3 can abut against the raised edge 9 to close the drainage groove 91. The drainage groove 91 has a V-shaped groove structure. The parts of the top plate 2 and the front panel 3 that contact the drainage groove 91 are provided with V-shaped blocks that cooperate with the V-shaped groove. This also provides a certain positioning and guiding function when closed, ensuring the complete closure of the cavity. In addition, the V-shaped groove has a certain slope to facilitate the guidance of water flow.

[0051] The drainage grooves 91 provided on the raised edge 9 form an orderly water flow guidance system. When it rains or the cargo compartment is being cleaned, the water falling on the top plate 2 and the front panel 3 will flow down their surfaces and cover the raised edge 9. The drainage grooves 91 can quickly collect the water and guide it to a specific direction to discharge it from the cargo compartment, thus avoiding water accumulation.

[0052] Please refer to Figure 1 In this embodiment, a plurality of fixing anchor rings 11 are also provided on the base plate 1. The fixing anchor rings 11 are evenly distributed at various positions on the base plate 1. The plurality of fixing anchor rings 11 provided on the base plate 1 provide a wide variety of fixing points for goods of different shapes, sizes and weights. Whether it is a regular-shaped box or an irregularly shaped mechanical equipment, pipes, etc., they can be connected to the fixing anchor rings 11 by ropes, straps or other tools to achieve a stable binding and fixing. Example 2

[0053] Please refer to Figure 6 The difference between this embodiment and embodiment 1 is that the first side of the top plate 2 is pivotally connected to the front panel 3. When the first side of the top plate 2 is pivotally connected to the front panel 3, a second driving mechanism 8 is provided between the top plate 2 and the front panel 3. The second driving mechanism 8 is used to drive the front panel 3 to rotate relative to the top plate 2 around the second side of the top plate 2.

[0054] While the front panel 3 flips open the interior space of the cargo box in sync with the top panel 2, it can also be opened or folded in conjunction. The second drive mechanism 8 drives the front panel 3 to flip around its connection point with the top panel 2, and the flipping direction can be upward or downward, further expanding the front opening and eliminating the obstruction of loading and unloading operations by the front panel 3. Especially when loading and unloading from the front of the cargo box or using equipment such as forklifts, it provides a smoother operating passage. Therefore, this embodiment can significantly improve loading and unloading efficiency and convenience, and has a wider range of application scenarios.

[0055] When the second drive mechanism 8 is provided, the second drive mechanism 8 includes a third support base 81 provided on the top plate 2, a fourth support base 82 provided on the front panel 3, and a second telescopic support member 83 with its two ends hinged to the third support base 81 and the fourth support base 82 respectively. That is, the second drive mechanism 8 of this application has the same structure and principle as the first drive mechanism 7, except that the second drive mechanism 8 is connected to the front panel 3 and the top plate 2. In addition, guide beams matching the third support base 81 and the fourth support base 82 can also be provided on the top plate 2 and the front panel 3, so that the position of the second drive mechanism 8 can also be adaptively adjusted.

[0056] In this embodiment, the second drive mechanism 8 enables the front panel 3 to be opened independently of the top panel 2. Thus, the opening between the front panel 3 and the top panel 2, as well as between the top panel 2 and the rear panel 4, involves both linked and independent operations, making the opening method more flexible and efficient, and improving the cargo compartment's adaptability to different loading and unloading scenarios. Example 3

[0057] Please refer to Figure 7 and Figure 8 The difference between this embodiment and Embodiment 1 is that the pivot joint 20 is located in the middle of the top plate 2. The top plate 2 is split into a first plate 21 connected to the rear panel 4 and a second plate 22 connected to the front panel 3 by the pivot joint 20. It can be understood that the pivot joint 20 makes the top plate 2 a split structure, allowing the user to choose the opening position of the top plate 2 according to actual needs, without having to open the entire top plate 2 simultaneously. This allows for more flexible adaptation to different usage scenarios and effectively reduces the load on the first drive mechanism 7, thereby reducing the requirements on the first drive mechanism 7 and increasing its service life.

[0058] Secondly, in another form, both the first plate 21 and the second plate 22 can rotate relative to the pivot position 20. The first drive mechanism 7 is arranged in two symmetrical sets, and the two sets of first drive mechanisms 7 are used to drive the rotation of the first plate 21 and the second plate 22 respectively.

[0059] The design of both the first plate 21 and the second plate 22 allows both the front panel 3 and the rear panel 4 to be opened, meaning the truck bed can be opened from both sides. This further improves the flexibility of the truck bed and makes it easier for forklifts and other loading and unloading equipment to load and unload goods from both sides of the truck bed at the same time, thus improving loading and unloading efficiency.

[0060] Of course, based on the rotatable first plate 21 and second plate 22, a second drive mechanism 8 can also be provided between the first plate 21 and the rear panel 4, and between the second plate 22 and the front panel 3.

[0061] It should be noted that the first telescopic support 73 and the second telescopic support 83 are electric push rods, hydraulic rods, or cylinders. There are two or more of the first drive mechanism 7 and the second drive mechanism 8.

[0062] Electric push rods, hydraulic rods, or cylinders can all achieve the telescopic drive function, and the diverse options allow users to flexibly choose different drive devices according to their actual needs. Two or more first drive mechanisms 7 and second drive mechanisms 8 can share the load and jointly bear the weight of the top plate 2 and the front panel 3 as well as the forces applied by the outside, which significantly improves the load-bearing capacity of the cargo box and reduces the probability of failure of a single drive mechanism due to excessive force.

[0063] In the description of this utility model, it should be understood that terms such as "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0064] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0065] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
