Description

Technical Field

[0001] This utility model relates to the field of vehicle body technology, and in particular to a vehicle body and vehicle. Background Technology

[0002] In related technologies, the cargo box, as a crucial load-bearing unit of the vehicle structure, not only undertakes the function of transporting materials, personnel, or equipment, but also needs to withstand loads from the frame, suspension system, and road impacts during operation. Therefore, the structural strength and rigidity of the cargo box have a vital impact on the safety, durability, and service life of the entire vehicle.

[0003] However, some of the vehicle body structures in related technologies are limited by material selection, manufacturing processes, or lightweight requirements during design, resulting in insufficient overall strength. When the vehicle is under heavy load, high speed, or complex operating conditions (such as frequent braking, turning, and bumpy roads), the vehicle body is prone to significant stress concentration, especially in critical areas such as joint welds and corners. Over long-term use, this may lead to cracks, deformation, or even structural breakage. Utility Model Content

The second reinforcing member and the first reinforcing member together define a first reinforcing cavity. The first reinforcing cavity is used to enhance the strength. If stress is concentrated, the first reinforcing cavity shares the stress, reducing the probability of cracks, deformation or structural cracking. Under the premise of ensuring the structural strength of the vehicle body, its crack resistance and overall structural stability are improved, thereby increasing the load capacity of the vehicle body and improving the design total mass of the vehicle under full load conditions, meeting the needs of carrying more loads.

[0013] In some embodiments, the shock absorber is made of shock-absorbing expansion rubber, and there are multiple positioning grooves that extend along the extension direction of the second reinforcing body; wherein at least some of the positioning grooves are provided with viewing holes that are configured to penetrate the second reinforcing body.

[0014] In some embodiments, the outer panel is provided with a headlight mounting hole for mounting a headlight. The first reinforcing cavity is lower than the height of the headlight mounting hole, and on a horizontal plane, the projection of the first reinforcing cavity is located within the projection range of the headlight mounting hole.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The vehicle body 100 of this utility model embodiment is described below with reference to the accompanying drawings.

[0035] Reference Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present utility model, a vehicle body 100 includes: an outer panel 10, a column 20, and a rear panel 30.

[0036] The outer panel 10 encloses a receiving space 11 for holding objects, and the receiving space 11 has a notch 111. The column 20 is connected to the outer panel 10, and the column 20 has a first mating part 21. The rear panel 30 is configured to move relative to the outer panel 10. The rear panel 30 is adapted to block the notch 111, and the rear panel 30 has a second mating part 31, which connects to the first mating part 21 to position the rear panel 30. The outer panel 10 and the column 20 together define a gap space 22. The gap space 22 has a first reinforcing member 23 and a second reinforcing member 24. The first reinforcing member 23 is connected to the column 20, and the second reinforcing member 24 is located on the first reinforcing member 23 on the side of the first reinforcing member 23 facing the outer panel 10. The second reinforcing member 24 and the first reinforcing member 23 together define a first reinforcing cavity 241.

[0037] The vehicle's cargo box 100 is used for placing people or objects, and the cargo box 100's accommodating space 11 is also used for placing people or objects. Specifically, the cargo box 100 is formed by multiple panel structures, including an outer panel 10 and a rear panel 30. The space enclosed by the outer panel 10 has a gap 111, and the rear panel 30 is located at the gap 111. The rear panel 30 is adapted to move relative to the outer panel 10. The rear panel 30 can move to block the gap 111 to prevent people or objects from falling into the accommodating space 11, and the rear panel 30 can move to open the gap 111 to facilitate the transfer of people or objects in the accommodating space 11.

[0038] The outer plate 10 is connected to a column 20, which plays a fixing role. The column 20 is provided with a first mating part 21, and the rear plate 30 is provided with a second mating part 31. The first mating part 21 and the second mating part 31 cooperate to position the rear plate 30, so that the rear plate 30 can move stably. For example, the first mating part 21 is a hole structure, and the second mating part 31 is a connecting column. The connecting column is rotatably provided in the hole structure, so that the rear plate 30 can rotate stably.

[0039] In related technologies, the cargo box, as a crucial load-bearing unit of the vehicle structure, not only undertakes the function of transporting materials, personnel, or equipment, but also needs to withstand loads from the frame, suspension system, and road impacts during operation. Therefore, the structural strength and rigidity of the cargo box have a vital impact on the safety, durability, and service life of the entire vehicle.

[0040] However, some vehicle body structures in related technologies are limited by material selection, manufacturing processes, or lightweight requirements during design, resulting in insufficient overall strength. When vehicles operate under heavy loads, high speeds, or complex conditions (such as frequent braking, turning, and bumpy roads), the vehicle body is prone to significant stress concentration, especially in critical areas such as welded joints and corners. Over long-term use, this can lead to cracks, deformation, or even structural breakage. This structural defect not only reduces the vehicle's load-bearing capacity and operational safety but may also cause increased maintenance costs and decreased operational reliability.

[0041] Therefore, how to improve the crack resistance and overall structural stability of the car body while ensuring its structural strength has become a key issue that related technologies urgently need to address.

[0042] In this embodiment of the utility model, a first reinforcing member 23 and a second reinforcing member 24 are provided in the gap space 22. The first reinforcing member 23 is connected to the column 20, and the second reinforcing member 24 is provided on the first reinforcing member 23. The second reinforcing member 24 is located on the side of the first reinforcing member 23 facing the outer plate 10. The second reinforcing member 24 and the first reinforcing member 23 together define a first reinforcing cavity 241. The strength of the carriage 100 is improved by using the first reinforcing cavity 241. For example, the first reinforcing cavity 241 is provided at the connecting weld, corner and other parts. If the stress is concentrated, the first reinforcing cavity 241 shares the stress, reducing the probability of cracks, deformation or structural cracking. Under the premise of ensuring the structural strength of the carriage 100, its crack resistance and overall structural stability are improved.

[0043] Meanwhile, compared with the integrally formed first and second reinforcing members in related technologies, the present invention is divided into two parts, which reduces costs.

[0044] Specifically, the rear plate 30 is configured to rotate relative to the outer plate 10. The rotation axis of the rear plate 30 is a horizontal axis, which allows the rear plate 30 to flip up and down, facilitating the entry and exit of materials, personnel and equipment. Of course, the rotation axis of the rear plate 30 can also be a vertical axis, which allows the rear plate 30 to flip left and right. Alternatively, the rear plate 30 can be configured to move relative to the outer plate 10. The specifics will not be elaborated here.

[0045] According to the embodiment of the present invention, the vehicle body 100 is provided with a first reinforcing member 23 and a second reinforcing member 24 in the gap space 22. The first reinforcing member 23 is connected to the column 20, and the second reinforcing member 24 is disposed on the first reinforcing member 23. The second reinforcing member 24 and the first reinforcing member 23 together define a first reinforcing cavity 241. The first reinforcing cavity 241 is used to enhance the strength. If the stress is concentrated, the first reinforcing cavity 241 shares the stress, reducing the probability of cracks, deformation or structural cracking. Under the premise of ensuring the structural strength of the vehicle body 100, its crack resistance and overall structural stability are improved, thereby increasing the load capacity of the vehicle body 100 and improving the design total mass of the vehicle under full load conditions, meeting the needs of carrying more loads.

[0046] Reference Figure 3 In some embodiments, the first reinforcing member 23 is provided with a third mating part 231, which mates with the second mating part 31 to position the rear plate 30.

[0047] The first reinforcing member 23 is provided with a third mating part 231, which mates with the second mating part 31. The first reinforcing member 23 plays a reinforcing role, and the second mating part 31 mates with both the first mating part 21 and the third mating part 231, making the rear plate 30 more stable.

[0048] In the above solution, by adding a third mating part 231 to the first mating part 21 to cooperate with the second mating part 31, and the second mating part 31 being located on the first reinforcing member 23, the rear plate 30 is made more stable, improving stability and reliability, further improving overall reliability, and reducing the probability of the rear plate 30 falling off.

[0049] Specifically, the third mating part 231 is a structural hole, and the second mating part 31 is a connecting post. The connecting post passes through the structural hole and is supported by the first reinforcing member 23, which improves the stability of the rear plate 30.

[0050] Reference Figure 2 , Figure 4 In some embodiments, the column 20 includes: a first plate 25 and a second plate 26.

[0051] The first plate 25 is connected to the outer plate 10, and the first mating part 21 is provided on the first plate 25. The second plate 26 is connected to the side of the first plate 25 away from the outer plate 10. The second plate 26 is at least partially constructed as a bent part 261, which bends toward the direction of the first reinforcing member 23. The bent part 261 and the first reinforcing member 23 together define the second reinforcing cavity 262.

[0052] The first plate 25 is connected to the second plate 26. The side of the first plate 25 closest to the outer plate 10 is connected to the outer plate 10. The second plate 26 is located on the side of the first plate 25 away from the outer plate 10. The second plate 26 is connected to the side of the first plate 25 away from the outer plate 10. The second plate 26 is at least partially constructed as a bent portion 261. The bent portion 261 is bent toward the direction of the first reinforcing member 23. The bent portion 261 and the first reinforcing member 23 together define a second reinforcing cavity 262. The second reinforcing cavity 262 between the bent portion 261 and the first reinforcing member 23 plays a reinforcing role. The second reinforcing cavity 262 works together with the surrounding components to improve the overall strength.

[0053] In the above solution, the second reinforcing cavity 262 is defined by the bending part 261 and the first reinforcing member 23. The second reinforcing cavity 262 works in coordination with the surrounding components to improve the overall strength, thereby reducing the probability of damage and improving reliability.

[0054] Specifically, the first plate 25 is located behind the second plate 26, the rear end of the first plate 25 is connected to the outer plate 10, the second plate 26 is located in front of the first plate 25, and the second plate 26 is bent to the right, the bent part being the bend 261.

[0055] Reference Figure 5 In some embodiments, the first reinforcing member 23 includes: a first connecting portion 232, a first reinforcing main body portion 233, and a second connecting portion 234.

[0056] The first connecting portion 232 is welded to the column 20. The first reinforcing main body portion 233 is connected to one end of the first connecting portion 232 and extends away from the first connecting portion 232. The second connecting portion 234 is welded to the column 20 and connects to the other end of the first reinforcing main body portion 233 away from the first connecting portion 232.

[0057] The first reinforcing member 23 is welded to the column 20 through the first connecting part 232 and the second connecting part 234. The first connecting part 232 and the second connecting part 234 are respectively located on opposite sides of the first reinforcing main body 233, thereby stabilizing the first reinforcing main body 233.

[0058] In the above solution, by setting a first connecting part 232 and a second connecting part 234 at both ends of the first reinforcing main body 233, and welding the first connecting part 232 and the second connecting part 234 to the column 20, the first reinforcing member 23 is stably fixed on the column 20. Welding at multiple parts improves connection stability, increases reliability, and reduces the probability of breakage.

[0059] Specifically, the first connecting part 232 is welded to the first plate 25, and the second connecting part 234 is welded to the second plate 26, respectively connecting to different parts, thereby improving the overall stability.

[0060] Reference Figure 5 In some embodiments, the second reinforcing member 24 includes a third connecting portion 242, a second reinforcing main body portion 243, and a fourth connecting portion 244.

[0061] The third connecting part 242 is welded to the first connecting part 232. The second reinforcing main body 243 is arc-shaped, and the second reinforcing main body 243 and the first reinforcing main body 233 together define the first reinforcing cavity 241. The fourth connecting part 244 is welded to the second connecting part 234.

[0062] The second reinforcing member 24 is welded to the column 20 through the third connecting part 242 and the fourth connecting part 244. The third connecting part 242 and the fourth connecting part 244 are respectively located on opposite sides of the second reinforcing main body 243, thereby stabilizing the second reinforcing main body 243.

[0063] In the above solution, by providing a third connecting part 242 and a fourth connecting part 244 at both ends of the second reinforcing main body 243, welding the third connecting part 242 to the first connecting part 232, and welding the fourth connecting part 244 to the second connecting part 234, the second reinforcing member 24 is stabilized. Welding multiple parts improves connection stability, increases reliability, and reduces the probability of breakage.

[0064] The second reinforcing main body 243 is arc-shaped. The arc-shaped second reinforcing main body 243 is adapted to special parts, such as the corner of the outer panel 10. The arc-shaped second reinforcing main body 243 can fit into the corner to support the stability of the outer panel 10.

[0065] Reference Figure 5 In some embodiments, the second reinforcing member 24 further includes a flange portion 245, which is disposed on the second reinforcing main body portion 243. The flange portion 245 is provided with a plurality of drainage holes 2451, which are spaced apart.

[0066] The flanged portion 245 is inclined relative to the second reinforcing main body portion 243. The flanged portion 245 is provided with multiple drainage holes 2451. It can be understood that after the second reinforcing member 24 undergoes electrophoresis, electrophoretic liquid may accumulate inside the second reinforcing member 24. During the subsequent drying process, a large amount of electrophoretic liquid may cause cracking, thereby increasing the probability of rusting later. In this embodiment of the present invention, the drainage holes 2451 play a role in draining liquid, and the multiple drainage holes 2451 drain the electrophoretic liquid accumulated inside.

[0067] In the above scheme, by providing a flanged part 245 on the second reinforcing main body 243, the strength is increased by providing the flanged part 245, and multiple drainage holes 2451 are provided on the flanged part 245 to drain a large amount of internal electrophoretic liquid, thereby reducing the probability of rusting in the later stage.

[0068] Specifically, there are two drain holes 2451, which are arranged alternately along the length of the flange 245 to improve the draining efficiency.

[0069] Reference Figure 5 In some embodiments, the second reinforcing member 24 further includes a flange 245, which is disposed on the second reinforcing main body 243 and has a weight-reducing drainage port 2452.

[0070] The flanged portion 245 is inclined relative to the second reinforcing main body portion 243. The flanged portion 245 is provided with a weight-reducing drain port 2452. It can be understood that after the second reinforcing member 24 undergoes electrophoresis, electrophoretic liquid may accumulate inside the second reinforcing member 24. During the subsequent drying process, a large amount of electrophoretic liquid may cause cracking, thereby increasing the probability of rusting later. In this embodiment of the present invention, the weight-reducing drain port 2452 plays a draining role, and the weight-reducing drain port 2452 discharges the electrophoretic liquid accumulated inside.

[0071] In the above solution, by providing a flange 245 on the second reinforcing main body 243, the strength is increased by providing the flange 245, and a weight-reducing drain port 2452 is provided on the flange 245 to drain more of the internal electrophoretic liquid, thereby reducing the probability of rusting in the later stage. At the same time, the weight-reducing drain port 2452 is used to reduce the weight of the second reinforcing member 24, thereby reducing the overall weight.

[0072] Reference Figure 5 In some embodiments, the second reinforcing member 24 further includes a flange 245, which is disposed on the second reinforcing main body 243. The flange 245 is provided with a plurality of drainage holes 2451, which are spaced apart. The flange 245 is also provided with a weight-reducing drainage port 2452.

[0073] The flanged portion 245 is inclined relative to the second reinforcing main body 243. The flanged portion 245 is provided with a weight-reducing drain port 2452 and multiple drain holes 2451. It can be understood that after the second reinforcing member 24 undergoes electrophoresis, electrophoretic liquid may accumulate inside the second reinforcing member 24. During the subsequent drying process, a large amount of electrophoretic liquid may cause cracking, thereby increasing the probability of rusting later. In this embodiment of the present invention, the weight-reducing drain port 2452 and the drain holes 2451 play a role in draining liquid, and the weight-reducing drain port 2452 and the multiple drain holes 2451 drain the electrophoretic liquid accumulated inside.

[0074] In the above solution, by providing a flanged portion 245 on the second reinforcing main body 243, the strength is increased by the flanged portion 245, and a weight-reducing drain port 2452 and multiple drain holes 2451 are provided on the flanged portion 245. The weight-reducing drain port 2452 and multiple drain holes 2451 are used to drain a large amount of internal electrophoretic liquid, reducing the probability of rusting in the later stage. At the same time, the weight-reducing drain port 2452 is used to reduce the weight of the second reinforcing member 24, thereby reducing the overall weight.

[0075] Reference Figure 1 , Figure 5 In some embodiments, the outer plate 10 has a corner portion 32, and the second reinforcing main body 243 is provided with a positioning groove 2431. A shock absorber is provided in the positioning groove 2431, and the shock absorber abuts against the inner wall of the corner portion 32.

[0076] The outer panel 10 has a corner portion 32. It is understood that stress concentration is more likely to occur at the corner portion in related technologies. The second reinforcing main body 243 is provided with a positioning groove 2431. The positioning groove 2431 is used to position the shock absorber. The shock absorber abuts against the inner wall of the corner portion 32 and provides a buffering effect.

[0077] In the above scheme, by setting the positioning groove 2431 to position the shock absorber, the probability of the shock absorber shifting is reduced, so that the shock absorber always abuts against the inner wall of the corner 32, and the shock absorber always plays a buffering role, thus improving the working stability.

[0078] Specifically, the shock absorber can be a shock-absorbing expansion adhesive, which is squeezed into the positioning groove 2431 and positioned using the positioning groove 2431. The shock absorber can also be an elastic sponge, which provides a cushioning effect based on its elasticity.

[0079] Reference Figure 1 , Figure 5 In some embodiments, the shock absorber is made of shock-absorbing expansion rubber, and the positioning groove 2431 is constructed in multiple ways, with the positioning groove 2431 extending along the extension direction of the second reinforcing main body 243; wherein, at least some of the positioning grooves 2431 are provided with a viewing hole 2433, which is configured to penetrate the second reinforcing main body 243.

[0080] The shock absorber is made of shock-absorbing expansion adhesive. The shock-absorbing expansion adhesive is extruded into the positioning groove 2431. After the shock-absorbing expansion adhesive solidifies, it is fixed in the positioning groove 2431. The positioning groove 2431 has a certain length and extends along the extension direction of the second reinforcing main body 243. The groove structure can further enhance the strength of the second reinforcing main body 243. The positioning groove 2431 is provided with a viewing hole 2433. The viewing hole 2433 is configured to penetrate the second reinforcing main body 243. Observers can view the shock-absorbing expansion adhesive on the inner side from the outside to determine whether shock-absorbing expansion adhesive has been sprayed.

[0081] In the above solution, by setting a positioning groove 2431 extending along the extension direction of the second reinforcing main body 243, the strength of the second reinforcing main body 243 is enhanced by the positioning groove 2431. At the same time, a viewing hole 2433 is provided on the positioning groove 2431 to determine whether to spray shock-absorbing expansion adhesive. The overall structure is simple and practical, reducing the error rate and improving production efficiency.

[0082] In some embodiments, the outer panel 10 is provided with a headlight mounting hole 12 for mounting a headlight. The headlight mounting hole 12 is used to mount a headlight. The first reinforcing cavity 241 is lower than the height of the headlight mounting hole 12. On the horizontal plane, the projection of the first reinforcing cavity 241 is located within the projection range of the headlight mounting hole 12.

[0083] The headlight mounting hole 12 on the outer panel 10 is used to install the headlight. The headlight is fixed on the outer panel 10. The first reinforcing member 23 and the second reinforcing member 24 are located below the headlight. The height of the first reinforcing cavity 241 is lower than the height of the headlight mounting hole 12. When the vehicle is on a horizontal plane, the projection of the first reinforcing cavity 241 on the horizontal plane is small. The projection of the first reinforcing cavity 241 is within the projection range of the headlight mounting hole 12. The first reinforcing cavity 241 is vertically aligned with the headlight mounting hole 12.

[0084] In the above scheme, on the horizontal plane, the projection of the first reinforcing cavity 241 is located within the projection range of the headlight mounting hole 12. Aligning the first reinforcing cavity 241 with the headlight mounting hole 12 reduces the probability of cracking around the headlight mounting hole 12 and improves structural durability.

[0085] Specifically, compared to related technologies, which are limited by the outer contour of the headlights and cannot optimize the corners to reduce stress, and are also affected by the stamping process, which prevents the addition of triangular ribs and other features for reinforcement, and since the corners are visible surfaces and cannot be reinforced by welding sheet metal parts, this utility model embodiment forms a Q-shaped structure by setting the first reinforcing member 23 and the second reinforcing member 24, which plays a reinforcing role and reduces the probability of the vehicle body 100 cracking.

[0086] The vehicle according to an embodiment of the present invention includes the aforementioned cargo box 100.

[0087] According to the vehicle of this utility model embodiment, a first reinforcing member 23 and a second reinforcing member 24 are provided in the gap space 22. The first reinforcing member 23 is connected to the column 20, and the second reinforcing member 24 is provided on the first reinforcing member 23. The second reinforcing member 24 and the first reinforcing member 23 together define a first reinforcing cavity 241. The first reinforcing cavity 241 is used to enhance the strength. If the stress is concentrated, the first reinforcing cavity 241 shares the stress, reducing the probability of cracks, deformation or structural cracking. Under the premise of ensuring the structural strength of the vehicle body 100, its crack resistance and overall structural stability are improved.

[0088] Other configurations and operations of the vehicle body 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
