Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a cargo box and a vehicle. Background Technology

[0002] The cargo box is the core unit of a vehicle such as a light truck. As the physical carrier for storing and transporting goods, the cargo box plays an irreplaceable role in ensuring the safety of goods and improving transportation efficiency.

[0003] However, vehicles in related technologies typically employ a standard rectangular cargo box design to maximize the utilization of internal space and increase the amount of cargo transported per trip. With the widespread adoption of new trucks, this cargo box structure results in significant wind resistance during vehicle operation, increasing vehicle drag and leading to lower energy efficiency. Utility Model Content

[0004] This application provides a cargo box and a vehicle to solve the problem that the cargo box has high wind resistance when the vehicle is running, which increases the vehicle's driving resistance and thus leads to low energy utilization.

[0008] In some optional embodiments, a plurality of first protrusions are spaced apart along the Y direction in the horizontal extension section, and a first air guide groove is formed between two adjacent first protrusions and the horizontal extension section. The first air guide groove extends along the X direction. A plurality of second protrusions are spaced apart along the Y direction in the inclined section, and a second air guide groove is formed between two adjacent second protrusions and the horizontal extension section. Each second air guide groove is connected to one of the first air guide grooves.

The first protrusion and the horizontal extension are integral structures, and the second protrusion and the inclined section are integral structures.

[0010] In some optional embodiments, the height of the first protrusion extending beyond the horizontal extension is m, and the height of the second protrusion extending beyond the inclined section is n, wherein 3mm ≤ m ≤ 8mm and 3mm ≤ n ≤ 8mm.

[0014] In some alternative embodiments, the cargo box further includes a side panel and a side skirt, the side panel being at least partially disposed between the top panel and the bottom panel, the side skirt being connected to the end of the side panel facing away from the top panel in the Z direction, and the side skirt extending from the front post to the rear post in the X direction.

By setting the top panel to be along the X direction and pointing from the front column to the rear column, the top panel includes a horizontally extending section and an inclined section distributed successively. One end of the inclined section is connected to the horizontally extending section, and the other end of the inclined section is inclined towards the side where the bottom panel is located. In the X direction, the length dimension of the top panel is d, the length dimension of the inclined section is c, 5% ≤ c / d ≤ 25%, and the angle e between the inclined direction of the inclined section and the X direction satisfies 2° < e ≤ 30°, thereby guiding the airflow to the rear of the cargo box, improving the vortex phenomenon at the rear of the cargo box, significantly reducing the vortex at the rear of the cargo box, which helps to reduce the negative pressure at the rear of the cargo box, reduce the wind resistance of the vehicle when the cargo box is in operation, and effectively improve the problem of low energy utilization of the vehicle.

Obviously, the described embodiments are merely some embodiments of this application, not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] In the field of cargo boxes, most existing vehicle cargo boxes adopt a standard rectangular structure design. This design aims to increase the amount of cargo transported in a single trip by maximizing the utilization of internal space. However, with the widespread application of new energy trucks, the drawbacks of the rectangular cargo box design have gradually become apparent. Especially when the vehicle is traveling at high speed, a large vortex area is easily formed at the rear of the cargo box, generating significant air turbulence, which in turn increases the drag of the vehicle.

[0037] The vortex at the rear of the cargo box not only increases the vehicle's drag coefficient but also consumes more energy. This is especially true for new energy trucks that rely on battery power, where increased drag directly shortens the vehicle's driving range and reduces its energy efficiency. Therefore, current cargo box designs fail to effectively consider fluid dynamics principles, particularly in reducing the vehicle's drag coefficient, leading to increased driving resistance and consequently, lower energy efficiency.

[0038] Based on this, this application provides a cargo box and a vehicle to solve the problem that the current cargo box has a large drag coefficient, which increases the vehicle's driving resistance and thus leads to low energy utilization.

[0039] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0040] See Figures 1 to 4 As shown, this application provides a cargo box 10, including a cargo box frame 1 and side panels 2. The cargo box frame 1 includes a front column 11 and a rear column 12 arranged along the X direction. The side panels 2 surround the cargo box frame 1 and define a storage space. The side panels 2 include a top panel 23 and a bottom panel 26 arranged along the Z direction on both sides of the cargo box frame 1. Along the X direction, from the front column 11 to the rear column 12, the top panel 23 includes a horizontally extending section 231 and an inclined section 232 successively distributed. One end of the inclined section 232 is connected to the horizontally extending section 231, and the other end of the inclined section 232 is inclined towards the side where the bottom panel 26 is located. Wherein, along the X direction, the length dimension of the top panel is d, the length dimension of the inclined section 232 is c, 5% ≤ c / d ≤ 25%, and the angle e between the inclined direction of the inclined section 232 and the X direction satisfies 2° ≤ e ≤ 30°.

[0041] Optionally, the direction is defined with reference to the vehicle coordinate system. For example, the X direction is parallel to the ground and points forward of the vehicle, used to describe the front-rear direction of the cargo box 10; the Y direction is parallel to the ground and points to the left side of the vehicle, used to describe the left-right direction of the cargo box 10; and the Z direction is parallel to the ground and points upward, used to describe the up-down direction of the cargo box 10.

[0042] Optionally, the cargo box frame 1 refers to the supporting structure of the cargo box 10, specifically a frame structure used to support the cargo box 10, provide a stable load-bearing environment for the goods, and connect to the chassis of the van. The cargo box frame 1 includes multiple columns, crossbeams, and longitudinal beams. These columns, crossbeams, and longitudinal beams are welded or bolted together to form a frame structure. The crossbeams and longitudinal beams constitute the basic skeleton of the cargo box frame 1, providing strength support for the cargo box 10 along the X and Y directions. The columns connect the crossbeams and longitudinal beams and also increase the overall stability of the cargo box frame 1.

[0043] Among the multiple columns of the cargo box frame 1, the column located in front of the cargo box frame 1 and facing the cab along the X direction is the front column 11, and the column located behind the cargo box frame 1 and away from the cab along the X direction is the rear column 12.

[0044] The side panels 2 are used to connect with the cargo box frame 1 and enclose a closed or semi-closed storage space. The side panels 2 can effectively prevent goods from scattering during transportation due to bumps, sudden braking, etc., ensuring the integrity and safety of the goods. In addition, the side panels 2, together with the crossbeams, longitudinal beams, and columns of the cargo box frame 1, can bear the weight of the goods and various forces generated during vehicle movement, enhancing the overall strength and stability of the cargo box 10.

[0045] The enclosure 2 may include a front panel 27, a rear panel 22, a top panel 23, a bottom panel 26, and a side panel 21, depending on its location. The front panel 27 is the panel located in front of the cargo box 10 along the X direction. The rear panel 22 is the panel located behind the cargo box 10 along the X direction. The side panels 21 are the panels located on the left and right sides of the cargo box 10 along the Y direction. The top panel 23 is the panel located above the cargo box 10 along the Z direction. The bottom panel 26 is the panel located below the cargo box 10 along the Z direction.

[0046] Optionally, the top panel 23 has two ends in the X direction, with the first end located on the side of the horizontal extension 231 away from the inclined section 232, and the second end located on the side of the inclined section 232 away from the horizontal extension 231. The length dimension d of the top panel 23 can be understood as the vertical distance between the two ends of the top panel 23 in the X direction.

[0047] Optionally, the length dimension c of the inclined segment 232 can be understood as: the vertical distance in the X direction between the end of the inclined segment 232 that connects with the horizontal extension segment 231 in the X direction and the end of the inclined segment 232 that is away from the horizontal extension segment 231.

[0048] Optionally, the included angle 'e' can be understood as the angle at which the inclined segment 232, with the end connected to the horizontal extension segment 231 as the center of rotation, deflects relative to the X direction and toward the side where the bottom panel 26 is located on the side away from the horizontal extension segment 231. Or it can be understood as the included angle between the inclined segment 232 and the horizontal plane.

[0049] Optionally, the inclined section 232 and the horizontal extension section 231 can be an integral structure or they can be separately formed and sealed together, for example, by welding, fastener fastening or other methods.

[0050] Optionally, the value of c / d can be any value between 5% and 25%, including both 5% and 25%. The value of the included angle e can be any value between 2° and 30°, including both 2° and 30°.

[0051] The cargo box 10 provided in this application includes a cargo box frame 1 and side panels 2. The cargo box frame 1 includes a front column 11 and a rear column 12 arranged along the X direction. The storage space formed by the side panels 2 and the cargo box frame 1 can be used to store goods. The side panels 2 include a top panel 23 and a bottom panel 26 arranged along the Z direction on both sides of the cargo box frame 1. The top panel 23 is arranged along the X direction, pointing from the front column 11 to the rear column 12. The top panel 23 includes a horizontally extending section 231 and an inclined section 232 distributed sequentially. One end of the inclined section 232 is connected to the horizontally extending section 231, and the other end of the inclined section 232 is inclined towards the side where the bottom panel 26 is located. Along the X direction, the length dimension of the top panel 23 is d, and the length dimension of the inclined section 232 is c, where 5% ≤ c / d ≤ 25%. The angle e between the inclined direction of the inclined section 232 and the X direction satisfies 2° < e ≤ 30°. See Appendix. Figure 5a , Figure 5b As can be seen from the cloud map, by designing the top panel 23 as a combination of a horizontal extension section 231 and an inclined section 232, the aerodynamic characteristics of the cargo box 10 are optimized. This allows for the guidance of airflow towards the rear of the cargo box 10, improving the vortex phenomenon at the rear of the cargo box 10. The inclined section 232 can effectively reduce the vortex region at the rear. Figure 5b The vortex region A2 in the middle is smaller than Figure 5aThe vortex zone A1 in the cargo box significantly reduces the vortex at the rear of the cargo box 10, which helps to reduce the negative pressure at the rear of the cargo box 10. Furthermore, the design of the inclined section 232 guides the airflow smoothly, reduces airflow separation, lowers the overall wind resistance of the vehicle when the cargo box 10 is in operation, and effectively improves the problem of low vehicle energy utilization. Especially in the application scenarios of new energy trucks, it can effectively extend the driving range.

[0052] In some optional embodiments, the cargo box 10 provided in one embodiment of this application has a top panel 23 with a length dimension d and an inclined section 232 with a length dimension c, where 10% ≤ c / d ≤ 20%, and the angle e between the inclined direction of the inclined section 232 and the X direction satisfies 4° ≤ e ≤ 20°. Through the above settings, the cargo box 10 provided in one embodiment of this application can effectively improve the vortex phenomenon at the rear of the cargo box 10, significantly reducing the vortex at the rear of the cargo box 10, lowering the drag coefficient of the vehicle on which the cargo box 10 is located, and effectively improving the problem of low vehicle energy utilization.

[0053] In some optional embodiments, c / d can be selected from 12% to 13%, for example, c / d can be selected from 12.1%, 12.2%, 12.3%, 12.4%, 12.5%, etc. e can be selected from 4° to 11°, for example, e can be selected from 4°, 4.4°, 4.5°, 5°, 10°, 10.1°, 10.2°, 10.3°, 10.4°, 10.5°, etc.

[0054] In some optional embodiments, the length dimension d of the top panel 23 of the cargo box 10 provided in one embodiment of this application satisfies the following range: 2m≤d≤17.5m.

[0055] The length dimension d of the top panel 23 can be any value between 2m and 17.5m, including both ends of the range.

[0056] One embodiment of this application provides a cargo box 10. Through the above-described configuration, this embodiment technically ensures that the cargo box 10 can maintain reasonable aerodynamic performance while meeting cargo storage requirements by limiting the length of the top panel 23. Furthermore, the technology in this embodiment can balance the storage capacity and wind resistance performance of the cargo box 10, achieving optimization between transportation efficiency and energy consumption for the vehicle.

[0057] In some alternative embodiments, the cargo box 10 provided in one embodiment of this application has a horizontal extension 231 and an inclined section 232 as an integral structure.

[0058] Alternatively, the horizontal extension 231 and the inclined section 232 can be formed from a single sheet material.

[0059] One embodiment of this application provides a cargo box 10, which, through an integrated structural design, enhances the integrity and sealing of the cargo box 10, avoids additional wind resistance caused by seams, and achieves excellent dustproof and waterproof effects. In other words, it improves the durability and waterproof performance of the cargo box 10, ensuring the safety of goods during transportation.

[0060] In some optional embodiments, the length dimension d of the top panel 23 is in the range of 4m ≤ d ≤ 12m. In some optional embodiments, the length dimension d of the top panel 23 can be 4.2m, 5.8m, or 7.4m.

[0061] Continue reading Figures 1 to 4 As shown, in some optional embodiments, in one embodiment of this application, a cargo box 10 has a horizontal extension section 231 with a plurality of first protrusions 28 spaced apart along the Y direction. A first air guide trough 30 is formed between two adjacent first protrusions 28 and the horizontal extension section 231. The first air guide trough 30 extends along the X direction. A plurality of second protrusions 29 are spaced apart along the Y direction. A second air guide trough 31 is formed between two adjacent second protrusions 29 and the horizontal extension section 231. Each second air guide trough 31 is connected to one of the first air guide troughs 30.

[0062] The first protrusion 28 can extend along the X direction, and the first protrusion 28 can be in the form of a polygonal strip structure. The extension direction of the first protrusion can be parallel to the horizontal extension segment 231. The cross-sectional shape of the first protrusion 28 in the X direction can be triangular, quadrilateral, etc.

[0063] The second protrusion 29 can extend along a direction forming an angle e with the X direction, and the second protrusion 29 can be a polygonal strip structure. The extension direction of the second protrusion 29 can be parallel to the inclined segment 232. The cross-sectional shape of the second protrusion 29 in its extension direction can be triangular, quadrilateral, etc.

[0064] One embodiment of this application provides a cargo box 10, which increases the structural strength of the top panel 23 and optimizes the airflow distribution by providing a first protrusion 28 and a second protrusion 29 on the top panel 23, and correspondingly forming a first air guide slot 30 and a second air guide slot 31. The design of the first protrusion 28, the second protrusion 29, the first air guide slot 30, and the second air guide slot 31 can guide the airflow along a preset path, reduce turbulence, and lower the drag coefficient during driving. This not only improves the mechanical performance of the cargo box 10, but also significantly reduces the vehicle's driving resistance and improves overall energy efficiency.

[0065] In some alternative embodiments, in one embodiment of this application, the cargo box 10 has a first protrusion 28 that protrudes into a horizontal extension section 231 in the direction away from the storage space, and a second protrusion 29 that protrudes into an inclined section 232 in the direction away from the storage space. The first protrusion 28 and the horizontal extension section 231 are integral structures, and the second protrusion 29 and the inclined section 232 are integral structures.

[0066] The first protrusion 28 may protrude from the horizontal extension 231 along the Z direction, or in other words, along a direction perpendicular to the plane of the horizontal extension 231. The second protrusion 29 may protrude from the inclined section 232 along a direction perpendicular to the plane of the inclined section 232.

[0067] The first protrusion 28 and the second protrusion 29 can also be an integral structure. That is to say, the horizontal extension 231, the inclined section 232, the first protrusion 28, and the second protrusion 29 can be an integral structure.

[0068] One embodiment of this application provides a cargo box 10 that avoids occupying storage space by placing the first protrusion 28 and the second protrusion 29 on the outer side of the top panel 23 away from the storage space, while simplifying the manufacturing process of the top panel 23. Furthermore, this arrangement of the first protrusion 28 and the second protrusion 29 helps to ensure a lower drag coefficient and improve the vehicle's energy efficiency without sacrificing cargo storage capacity.

[0069] In some optional embodiments, the cargo box 10 provided in one embodiment of this application has a first protrusion 28 protruding from the horizontal extension section 231 with a height dimension of m, and a second protrusion 29 protruding from the inclined section 232 with a height dimension of n, wherein 3mm≤m≤8mm and 3mm≤n≤8mm.

[0070] The first protrusion 28 protrudes from the horizontal extension 231 along the Z direction, or in other words, in a direction perpendicular to the plane of the horizontal extension 231. The height of the first protrusion 28 is m. The value of m can be any value between 3mm and 8mm, and 5mm can be selected.

[0071] The second protrusion 29 protrudes from the inclined section 232 in a direction perpendicular to the plane of the inclined section 232, with a height dimension of n. The value of n can be any value between 3mm and 8mm, and 5mm can be selected.

[0072] Optionally, m and n can have the same value.

[0073] One embodiment of this application provides a cargo box 10 that ensures a balance between the structural strength and aerodynamic performance of the top panel 23 by limiting the protrusion height of the first protrusion 28 and the second protrusion 29. The choice of height directly affects the airflow guidance effect and the pressure resistance of the top panel 23. The above arrangement can effectively ensure the rigidity of the top panel 23 while reducing wind resistance, ensuring the stability and economy of the vehicle at high speeds.

[0074] In some alternative embodiments, the cargo box 10 provided in one embodiment of this application has the same number of first protrusions 28 and second protrusions 29 and is arranged one-to-one, with each first protrusion 28 and the oppositely arranged second protrusion 29 being an integral structure.

[0075] The angle between the extension direction of each first protrusion 28 and the extension direction of the corresponding second protrusion 29 is the same as the angle e between the inclination direction of the inclined segment 232 and the X direction.

[0076] One embodiment of this application provides a cargo box 10 that forms a continuous airflow channel by matching the number and position of the first protrusion 28 and the second protrusion 29, thereby optimizing the airflow distribution. In principle, this arrangement ensures a smooth transition of airflow over the top panel 23, reducing the generation of vortices. This effectively reduces the drag coefficient and improves vehicle driving efficiency.

[0077] In some optional embodiments, the cargo box 10 provided in one embodiment of this application includes a front panel 27 and a rear panel 22 distributed along the X direction, and a top panel 23 covering the front panel 27 and the rear panel 22. The top panel 23 also includes a blocking section 233, which extends along the inclined direction of the inclined section 232 and is integral with the inclined section 232. In the X direction, the inclined section 232 protrudes from the rear panel 22.

[0078] The portion protruding from the rear panel 22 in the X direction and away from the storage space can be understood as the blocking section 233, and the portion that is inclined and in the direction away from the storage space but does not protrude from the rear panel 22 can be understood as the inclined section 232.

[0079] One embodiment of this application provides a cargo box 10, which provides additional protection by adding a shielding section 233 to the top panel 23 to prevent rainwater from directly intruding into the interior of the cargo box 10. In principle, the shielding section 233 is designed to block direct wind and rain from the rear without affecting normal airflow. In terms of effectiveness, the technology in this embodiment improves the waterproof performance of the cargo box 10, protecting goods from severe weather while maintaining low wind resistance. In other embodiments, drainage holes or guide channels can be added to the shielding section 233 to accelerate rainwater drainage and solve the problem of water accumulation during prolonged rainy weather.

[0080] In some optional embodiments, the cargo box 10 provided in one embodiment of this application further includes a side panel 21 and an arc-shaped panel 24. The side panel 21 is at least partially disposed between the top panel 23 and the bottom panel 26, and the arc-shaped panel 24 is connected between the top panel 23 and the side panel 21. The arc radius of the arc-shaped panel 24 is any value from 40mm to 80mm, including two end values ​​of 40mm and 80mm.

[0081] In one embodiment of this application, the top panel 23 and the side panel 21 are connected at their closest points by an arc-shaped plate 24. The radius of the arc of the arc-shaped plate 24 is greater than or equal to mm, forming a large-rounded arc-shaped plate 24. This large-rounded arc-shaped plate 24 reduces the frontal area of ​​the van during driving, further reducing the drag coefficient of the cargo box 10. In other words, this embodiment improves the external profile of the cargo box 10 by setting an arc-shaped plate 24 between the side panel 21 and the top panel 23, making it more aerodynamic. By setting the arc of the arc-shaped plate 24 to less than or equal to 80 mm, the drag coefficient can be reduced while correspondingly increasing the storage space and improving the cargo-carrying capacity of the cargo box 10.

[0082] As an alternative implementation, the radius of curvature of the arc plate 24 can be set to one of 40mm, 50mm, 55mm, 60mm, 70mm, 80mm, etc., in order to reduce the wind resistance coefficient of the cargo box 10 while taking into account the storage space of the cargo box 10 and improving the performance of the van.

[0083] In other embodiments, different curvatures of the arc plate 24 can be used, or guide fins can be added to the arc plate 24 to adapt to different vehicle speeds and driving environments, and solve the problems of wind resistance and airflow guidance under specific conditions.

[0084] In some alternative embodiments, one embodiment of the present application provides a cargo box 10, which further includes a side panel 21 and a side skirt 25. The side panel 21 is at least partially disposed between the top panel 23 and the bottom panel 26. The side skirt 25 is connected to one end of the side panel 21 that is away from the top panel 23 in the Z direction. The side skirt 25 extends from the front pillar 11 to the rear pillar 12 in the X direction.

[0085] By providing a side skirt 25 below the side panel 21 of the cargo box 10, and extending the side skirt 25 from the front pillar 11 to the rear pillar 12 in the X direction, the side skirt 25 can have a complete side structure, which can effectively reduce the risk of air entering the lower part of the bottom panel 26 of the cargo box 10, and allow more air from the side of the cargo box 10 to be directed to the rear of the cargo box 10, effectively reducing the wind resistance of the whole vehicle.

[0086] Optionally, the side skirt 25 is provided with a clearance part at one end near the rear pillar 12, which can reduce the risk of the side skirt 25 interfering with road obstacles (such as bumps, slopes, speed bumps or potholes) and improve the passability, safety and reliability of the van.

[0087] In some optional embodiments, one embodiment of the present application provides a cargo box 10 with a door opening on the side panel 21. The cargo box 10 also includes a side door 3 and a door lock 4. The side door 3 is connected to the side panel 2 and covers the door opening, and the door lock 4 is hidden inside the side door 3. Technically, this embodiment avoids the door lock 4 becoming an additional source of wind resistance during driving by hiding it inside the side door 3. In principle, the hidden door lock 4 design reduces the exposed structure, making airflow smoother.

[0088] One aspect of this application provides a vehicle including a cargo box 10 as described in any of the above claims, the vehicle being optionally a light truck.

[0089] The vehicle provided in one embodiment of this application includes a cargo box 10 as described in the above embodiments. The storage space formed by the side panels 2 and the cargo box frame 1 can be used to store goods. Furthermore, the structural design of the cargo box 10 can guide the airflow to the rear of the cargo box 10, improving the vortex phenomenon at the rear of the cargo box 10, significantly reducing the vortex at the rear of the cargo box 10, lowering the drag coefficient of the vehicle, and effectively improving the problem of low vehicle energy utilization. This can significantly reduce the vehicle's driving resistance, increase the vehicle's driving speed and range, especially in new energy vehicles, effectively extending the driving distance. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
