[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] As described in the background technology, the cargo box of existing pickup trucks or other load-bearing vehicles with cargo boxes is connected to the frame through a cargo box mounting bracket. The cargo box mounting bracket includes a main support plate and side support plates located on both sides of the main support plate. The two side support plates are located on the same side of the main support plate surface, so that the main support plate and the two side support plates are spliced ​​and welded to form a support cavity, and the support cavity is specifically located on the opposite side of the main support plate. The main support plate is used to connect to the cargo box, or also to connect to the wheel cover of the frame, and the side support plate is used to connect to the longitudinal beam and wheel cover of the frame, specifically by welding, and at least two welding points are set between each side support plate and the frame.

[0037] However, since the frame longitudinal beams of some vehicle models have two inherent reinforcement structures on both sides of the installation location of the cargo box mounting bracket, the two reinforcement structures fail to overlap effectively and form a gap that matches the cargo box mounting bracket, resulting in a sudden change in stiffness of the longitudinal beam at the installation location of the cargo box mounting bracket. During vehicle operation, the inherent reinforcement structures on both sides of the cargo box mounting bracket will produce relative displacement, thereby causing the cargo box mounting bracket to deform together, resulting in the weld between the cargo box mounting bracket and the vehicle frame to crack easily.

[0038] In order to overcome the defects in the prior art, the present application provides a cargo box mounting bracket and a vehicle. The cargo box mounting bracket is provided with a reinforcement member on one side of the bracket body, so that the reinforcement member is connected to both the main support member and the side support member, so as to strengthen the structural strength of the cargo box mounting bracket, alleviate the excessive deformation of the bracket body with the longitudinal beam, and prevent the welds between the cargo box mounting bracket and the longitudinal beam from cracking.

[0039] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0040] On the one hand, referring to Figure 1 , Figure 2 and Figure 6 As shown, an embodiment of the present application provides a cargo box mounting bracket, including a bracket body 100 and a reinforcement 200, the bracket body 100 includes a main support 120 and two side supports 130 respectively arranged on opposite sides of the main support 120, the main support 120 is used to connect to the cargo box, and the side support 130 is used to connect to the frame 300 of the vehicle; the main support 120 and the two side supports 130 surround a support cavity 110, the reinforcement 200 is located in the support cavity 110, and is connected to both the main support 120 and the side supports 130.

[0041] Need to explain, Figures 1 to 6 The X, Y, and Z directions shown in FIG. 1 are perpendicular to each other in the three-dimensional space.

[0042] It can be understood that the bracket body 100 of the cargo box mounting bracket is arranged at the mounting position of the longitudinal beam of the frame 300, the longitudinal beam of the frame 300 extends along the X direction, and the bracket body 100 is located above the longitudinal beam as a whole along the Z direction, that is, the side support 130 of the bracket body 100 is connected to the upper surface of the longitudinal beam along the Z direction along the lower surface of the Z direction, and the longitudinal beam has inherent reinforcement structures on both sides of the mounting position along the X direction, and the side support 130 of the bracket body 100 is connected to the longitudinal beam and the inherent reinforcement structures on both sides along the X direction.

[0043] In this way, the bracket body 100 of the cargo box mounting bracket can be set on the frame 300 along the Z direction, specifically welded to the longitudinal beam of the frame 300 and the wheel cover structure of the frame 300, and the cargo box is set on the main support 120 of the bracket body 100 on the side away from the longitudinal beam along the Z direction, and a mounting hole for connecting with the cargo box by bolts is opened on the main support 120.

[0044] In this way, the reinforcement 200 is provided and located in the support cavity 110, and the reinforcement 200 is connected to the side support 130 and the main support 120, so that the reinforcement 200 is just located between the intervals of the reinforcement structures on both sides, and is connected to the reinforcement structures on both sides through the side support 130, and then the reinforcement 200 can be used to improve the structural strength of the support body 100, so that the stability of the structure can be improved, thereby alleviating the influence of the deformation of the longitudinal beam of the frame 300 on the support body 100, and reducing the possibility of cracking and failure of the weld between the support body 100 and the frame 300.

[0045] When the reinforcement 200 is further connected to the installation position between the two reinforcement structures of the frame 300 through the two side supports 130 arranged along the X direction, the reinforcement 200 can be located at the installation position, and the reinforcement 200 is used to achieve an effective connection between the two reinforcement structures, thereby alleviating the sudden change in stiffness of the longitudinal beam of the frame 300 at this position. In the subsequent driving process of the vehicle, the deformation degree of the longitudinal beam of the frame 300 due to the relative displacement between the two reinforcement structures is reduced, and the influence on the cargo box mounting bracket is also reduced, thereby further reducing the possibility of cracking and failure of the welding point between the bracket body 100 and the frame 300.

[0046] Therefore, the cargo box mounting bracket provided in the embodiment of the present application, by arranging a reinforcement 200 in the support cavity 110 of the bracket body 100, so that the reinforcement 200 is connected to both the main support 120 and the side support 130, so as to utilize the reinforcement 200 to improve the structural strength of the bracket body 100, and after the cargo box mounting bracket is connected to the frame 300, the reinforcement 200 can be utilized to mitigate the sudden change in stiffness of the longitudinal beam at that location, alleviate the excessive deformation of the bracket body 100 with the longitudinal beam, and thereby prevent the welds between the cargo box mounting bracket and the longitudinal beam from cracking.

[0047] Furthermore, compared to the existing cargo box mounting bracket which only has a bracket body 100, the cargo box mounting bracket provided in the embodiment of the present application is provided with a reinforcement member 200 in the support cavity 110, and does not increase the occupied volume of the overall space. Therefore, it will not interfere with surrounding structural members during assembly, thus avoiding the need to readjust the surrounding structure of the frame 300 and saving assembly costs.

[0048] In some embodiments, reference Figures 1 to 4 As shown, the main support member 120 includes a support plate portion 121 and a bending portion connected to the support plate portion 121 , and the bending portion is connected to the reinforcement member 200 , thereby improving the structural strength of the support body.

[0049] For details, please refer to Figures 1 to 4 As shown, the bending portion includes a first bending section 122, a second bending section 123 and a third bending section 124 arranged in sequence, the first bending section 122 is connected to the support plate portion 121, the second bending section 123 is opposite to the support plate portion 121, and the third bending section 124 extends toward a side away from the support plate portion 121;

[0050] The support plate portion 121 , the first bending section 122 , the second bending section 123 and the third bending section 124 are all connected to the side support member 130 , and the third bending section 124 is connected to the reinforcement member 200 .

[0051] The support plate portion 121 extends in the opposite direction of the Y direction, the first bending section 122 extends in the opposite direction of the Z direction, the second bending section 123 extends in the opposite direction to the support plate portion 121, and the third bending section 124 extends in the opposite direction to the first bending section 122. By sequentially arranging the first bending section 122, the second bending section 123 and the third bending section 124 that are bent on one side of the support plate portion 121, and making the projections of the second bending section 123 and the third bending section 124 toward the support plate portion 121 along the Z direction as shown in FIG. Figure 4 As shown in the figure, they are all located inside the support plate portion 121, so that a stepped bending structure is formed on one side of the support plate portion 121, so that the side support 130 can be connected to the main support 120 from at least three side edges, thereby improving the structural stability of the cargo box mounting bracket.

[0052] In addition, the stepped bending structure improves the structural stability of the cargo box mounting bracket, and can further ensure the reliability of the connection between the cargo box mounting bracket and the cargo box.

[0053] In a specific implementation, sheet metal parts corresponding to the main support 120 and the two side supports 130 can be respectively provided, and flanges facing the support cavity 110 are provided at the corresponding connecting parts of the main support 120 and the side supports 130, and the main support 120 and the side supports 130 are welded through the flanges, so as to make the cargo box mounting bracket structure compact and reduce the occupation of external space.

[0054] A plurality of weight-reducing holes 212 are provided on the two side supports 130 and the support plate portion 121 , and the weight-reducing holes 212 structure is recessed or convex relative to the plane where the side supports 130 are located, thereby reducing the weight of the cargo box mounting bracket structure and improving the supporting capacity of the side supports 130 .

[0055] Further, see Figure 1 and Figure 5 As shown, the reinforcement member 200 includes a support portion 210, a first connection portion 220 and two second connection portions 230, wherein the first connection portion 220 is disposed on one side of the support portion 210, and the two second connection portions 230 are respectively disposed on opposite sides of the support portion 210 adjacent to the first connection portion 220;

[0056] The support portion 210 is connected to the third bending segment 124 via the first connection portion 220 , and the support portion 210 is connected to the side support member 130 via the second connection portion 230 .

[0057] The support portion 210 is arranged in this way, and the first connection portion 220 is arranged on a side of the support portion 210 corresponding to the third bending section 124 in the opposite direction of the Y direction, so that the support portion 210 is connected to the third bending section 124 through the first connection portion 220, and two second connection portions 230 are respectively arranged on the sides of the support portion 210 corresponding to the side branches 130 on both sides along the X direction, so that the second connection portions 230 are respectively adjacent to the first connection portions 220, and are connected to the side branches 130 through the second connection portions 230 on both sides, so that a stable connection between the reinforcement member 200 and the main branch 120 and the side branch 130 can be achieved.

[0058] In a specific implementation, the first connection part 220 and the second connection part 230 are both located on the side of the support part 210 facing the support cavity 110, so that after the first connection part 220 and the second connection part 230 are respectively connected to the bracket body 100, the whole can be located in the support cavity 110, and the support part 210 forms a shield, so that the cargo box installation bracket structure is compact and the occupancy of the external space is reduced.

[0059] In addition, continue to refer to Figure 1 and Figure 5 As shown, the reinforcement 200 further includes a third connection portion 240 , which is disposed on the support portion 210 . The third connection portion 240 is opposite to the first connection portion 220 , and is used to connect to the vehicle frame 300 .

[0060] By providing a third connection portion 240 opposite to the first connection portion 220 on the support portion 210 along the Y direction, the third connection portion 240 is connected to the vehicle frame 300, specifically, the third connection portion 240 can be connected to the longitudinal beam or the wheel housing. In this way, the number of connection points between the cargo box mounting bracket and the vehicle frame 300 can be increased, and the reliability of the connection between the cargo box mounting bracket and the vehicle frame 300 can be further improved.

[0061] The third connection portion 240 is different from the first connection portion 220 and the second connection portion 230 in that the third connection portion 240 is not limited to being disposed toward the support cavity 110, but may also be disposed away from the support cavity 110 to facilitate the arrangement of welding points during subsequent connection.

[0062] In specific implementation, refer to Figure 5 As shown, the first connection portion 220 , the second connection portion 230 and the third connection portion 240 are all first flanges.

[0063] It can be understood that the first connection part 220, the second connection part 230 and the third connection part 240 are all set as the first flange, the overall structure is simple and compact, and can be directly welded to the parts that need to be connected, and the connection method is simple and reliable.

[0064] Furthermore, such an arrangement can make the reinforcement an integrally formed part, and a sheet metal part is used as a blank of the reinforcement 200. The reinforcement 200 can be formed by stamping and bending the blank, wherein the support portion 210 is a plate structure, and the first connecting portion 220, the second connecting portion 230 and the third connecting portion 240 are all first flanges formed by bending, which is simple to process and has a low processing cost.

[0065] Further, see Figure 1 and Figure 5 As shown, the support portion 210 is parallel to the support plate portion 121 .

[0066] After the reinforcement 200 is connected to the bracket body 100, the extension direction of the support portion 210 is consistent with the extension direction of the support plate portion 121, and both extend in the opposite direction of the Y direction. Since the extension direction of the support plate portion 121 is usually consistent with the extension direction of the installation point of the cargo box and the frame 300, the support portion 210 can fully fill the gap between the reinforcement structure of the frame 300, further reduce the sudden change in the stiffness of the longitudinal beam of the frame 300 at this location, and effectively reduce the possibility of cracking and failure of the weld between the cargo box mounting bracket and the frame 300.

[0067] In some embodiments, at least one of a reinforcing rib 211 and a lightening hole 212 is disposed on the support portion 210 .

[0068] It is easy to understand that by providing reinforcing ribs 211 on the support portion 210, the structural strength of the support portion 210 can be improved, thereby improving the supporting stability of the support portion 210 on the bracket body 100. By providing the weight-reducing holes 212, the weight of the reinforcement 200 can be reduced while ensuring the structural strength of the support portion 210, thereby reducing the overall weight of the cargo box mounting bracket.

[0069] In this embodiment, the support portion 210 is provided with both reinforcing ribs 211 and weight-reducing holes 212, the reinforcing ribs 211 are located in the middle of the support portion 210 and extend along the Y direction, and the weight-reducing holes 212 are evenly distributed on both sides of the reinforcing ribs 211. In other embodiments, only one of the reinforcing ribs 211 and the weight-reducing holes 212 may be provided, and this application does not limit this.

[0070] In some other embodiments, reference Figures 1 to 4 ,and Figure 6 As shown, the main support 120 and the two side supports 130 all have a second flange 111 , and the second flange 111 is used for welding with the vehicle frame 300 .

[0071] In this way, the second flanges 111 are used to realize the connection between the support body 100 and the frame 300, which is convenient for the arrangement of welding points and has a simple structure. In specific implementation, each second flange 111 extends away from the support cavity 110, so as to facilitate the subsequent welding and simplify the operation.

[0072] The second flanges 111 on the two side supports 130 can be connected to the longitudinal beams and wheel housings of the vehicle frame 300 , and the second flanges 111 on the main support 120 are connected to the wheel housings of the vehicle frame 300 .

[0073] On the other hand, an embodiment of the present application provides a vehicle, including a vehicle body and a cargo box mounting bracket in any of the above embodiments, the vehicle body having a frame 300 and a cargo box, and the frame 300 is connected to the cargo box via the cargo box mounting bracket.

[0074] Among them, the cargo box mounting bracket has been described in detail in the above embodiment and will not be repeated here.

[0075] In summary, the cargo box mounting bracket and vehicle provided by the present application, the cargo box mounting bracket arranges a reinforcement 200 in the support cavity 110 of the bracket body 100, so that the reinforcement 200 is connected to both the main support 120 and the side support 130, so as to utilize the reinforcement 200 to improve the structural strength of the bracket body 100, and after the cargo box mounting bracket is connected to the frame 300, the reinforcement 200 can be utilized to mitigate the sudden change in stiffness of the longitudinal beam at that location, alleviate the excessive deformation of the bracket body 100 with the longitudinal beam, and thereby prevent the cracking and failure of the welds between the cargo box mounting bracket and the longitudinal beam.
