DETAILED DESCRIPTION

[0026] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0027] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0028] Next, the embodiments of the present application are described in detail.

[0029] like Figure 1 and Figure 2As shown, the present application provides a cargo box frame, including a cargo box cross beam 10, a cargo box vertical beam 20, a pair of upper side beams 30 and a connecting member 40. The cargo box cross beam 10 is located at the bottom of the cargo box frame and extends along the width direction of the vehicle body. The cargo box vertical beams 20 are located at both ends of the cargo box cross beam 10 and extend along the height direction of the vehicle body. A pair of upper side beams 30 extend along the length direction of the vehicle body, and the upper ends of the cargo box vertical beams 20 are fixed to the upper side beams 30. The connecting member 40 is arranged between the cargo box cross beam 10 and the cargo box vertical beam 20, and the two ends of the connecting member 40 are respectively fixed to the bottom of the cargo box vertical beam 20 and the cargo box cross beam 10.

[0030] The cargo box cross beam 10 includes, from front to back, a first cargo box cross beam 11, a second cargo box cross beam 12 and a third cargo box cross beam 13. The first cargo box cross beam 11, the second cargo box cross beam 12 and the third cargo box cross beam 13 are arranged in parallel and evenly distributed. The third cargo box cross beam 13 is located at the rear end of the cargo box frame.

[0031] Correspondingly, the cargo box vertical beam 20 includes a pair of first vertical beams 21, a pair of second vertical beams 22 and a pair of D-pillars 23. The pair of first vertical beams 21 are respectively located at the two ends of the first cross beam 11 of the cargo box. The pair of second vertical beams 22 are respectively located at the two ends of the second cross beam 12 of the cargo box. The pair of D-pillars 23 are respectively located at the two ends of the third cross beam 13 of the cargo box, and the D-pillars 23 are located at the rearmost end of the cargo box frame. The upper ends of the first vertical beam 21, the second vertical beam 22 and the D-pillars 23 are fixedly connected to the upper side beam 30. The lower parts of the first vertical beam 21 and the second vertical beam 22 are both protruding toward the inner side of the vehicle body to form a wheel avoidance space.

[0032] The connecting member 40 includes a pair of first connecting members 41, a pair of second connecting members 42 and a pair of third connecting members 43. The first connecting member 41 connects the first cross beam 11 of the cargo box with the first vertical beam 21. The second connecting member 42 connects the second cross beam 12 of the cargo box with the second vertical beam 22. The third connecting member 43 connects the third cross beam 13 of the cargo box with the D-pillar 23.

[0033] Furthermore, the cargo box frame of the present application further includes a pair of C-pillars 80 and a rear panel 90 located at the front end of the cargo box. The rear panel 90 connects the pair of C-pillars 80. The front end of the upper side beam 30 is fixedly connected to the C-pillar 80.

[0034] The cargo box cross beam 10 of the cargo box frame of the present application is connected to the cargo box vertical beam 20 at both ends, and the upper end of the cargo box vertical beam 20 is connected to the upper side beam 30. The cargo box cross beam 10, the cargo box vertical beam 20 and the upper side beam 30 together form a skeletal frame structure, which has strong structural stability, can effectively improve the bending stiffness and torsional stiffness of the cargo box frame, reduce problems such as resonance noise of the pickup truck cargo box, and improve the quality of the pickup truck model.

[0035] At the same time, since the overall skeletal frame structure has strong structural stability, the four to five cargo box beams of a traditional pickup truck can be streamlined to three evenly distributed cargo box beams 10 while meeting the overall strength and rigidity requirements, further reducing the weight and cost of the pickup truck.

[0036] In order to further improve the stability of the cargo box frame, the cargo box frame is also provided with a first reinforcing beam 51 and a second reinforcing beam 52 extending along the length direction of the vehicle body. In the present application, the two ends of the first reinforcing beam 51 are respectively fixed to the first connecting member 41 and the second connecting member 42, and the two ends of the second reinforcing beam 52 are respectively fixed to the second vertical beam 22 and the D-pillar 23. In some cases, the two ends of the first reinforcing beam 51 can also be respectively fixed to the first vertical beam 21 and the second vertical beam 22, and the two ends of the second reinforcing beam 52 can also be respectively fixed to the second connecting member 42 and the third connecting member 43.

[0037] Specifically, the cargo box frame of the present application adopts a hybrid design of upper steel and lower aluminum, which takes into account the needs of strength and lightweight. The material of the cargo box cross beam 10 is high-strength aluminum alloy, and the materials of the cargo box vertical beam 20, the upper side beam 30, the connecting piece 40, the first reinforcing beam 51 and the second reinforcing beam 52 are all high-strength steel. Since the density of aluminum is only 1 / 3 of that of steel, the use of the cargo box cross beam 10 made of aluminum alloy can reduce the overall weight of the cargo box frame by about 25%, which is beneficial to reduce the weight of the vehicle body and improve the power economy of pickup trucks (especially new energy pickup trucks). The cargo box cross beam 10 is formed by extrusion process. Compared with the stamping die of steel parts, the development cost of the extrusion die of aluminum material is lower, which can reduce the mold investment cost of the cargo box frame.

[0038] like Figure 3 and Figure 4 As shown, the cargo box cross beam 10 includes an upper wall 101, a lower wall 102 and a pair of side walls 103. A cavity 104 is formed in the cargo box cross beam 10, and a reinforcing rib 105 is arranged in the cavity to strengthen the rigidity and strength of the cargo box cross beam 10 body, thereby improving the load-bearing capacity of the cargo box. In the present application, the reinforcing rib 105 is arranged in a plate shape, and its upper and lower ends are respectively connected to the upper wall 101 and the lower wall 102 of the cargo box cross beam, and extend along the length direction of the cargo box cross beam 10. In the same cargo box cross beam 10, the number of reinforcing ribs 105 is two, which divides the cavity 104 into three parts. It can be understood that the number and shape of the reinforcing ribs 105 can be flexibly designed according to actual needs.

[0039] The connecting member 40 includes a first connecting portion 401 connected to the cargo box cross beam 10 and a second connecting portion 402 connected to the cargo box vertical beam 20. The first connecting portion 401 is arranged horizontally, and one end close to the inner side of the vehicle body is sleeved outside the cargo box cross beam 10 and partially overlaps with the cargo box cross beam 10. The second connecting portion 402 is folded upward from one end of the first connecting portion 401 close to the outer side of the vehicle body.

[0040] The first connection part 401 is connected to the cargo box cross beam 10 by a fastener 60, the second connection part 402 is fixed to the cargo box vertical beam 20 by spot welding, and the cargo box vertical beam 20 is fixed to the upper side beam 30 by spot welding. Due to the difference in melting point and thermal expansion coefficient between aluminum alloy and high-strength steel, it is difficult to fix them by welding, and the production line needs to be redesigned or modified.

[0041] In the cargo box frame of the present application, the connection between the steel connecting part 40 and the aluminum cargo box cross beam 10 is achieved by fasteners 60, and the connection between the steel connecting part 40, the steel cargo box vertical beam 20 and the steel upper side beam 30 is achieved by spot welding, so that the cargo box frame of the present application is compatible with the traditional welding production line, and there is no need to modify the production line for the use of aluminum alloy, which reduces the difficulty of the steel-aluminum connection process and reduces the investment in production line modification.

[0042] Specifically, the fastener 60 of the present application is a bolt. Eight fasteners 60 are provided at one end of each cargo box cross beam 10, of which four fasteners 60 are distributed on the upper wall 101, and the other four fasteners 60 are distributed on the lower wall 102. The type, quantity and distribution of the fasteners 60 can be flexibly designed according to actual needs.

[0043] like Figure 5 and Figure 6 As shown, the bottom of the cargo box frame is connected to the vehicle frame 70 by fasteners 60. The cargo box cross beam 10 is provided with a mounting portion 14, and the mounting portion 14 includes a mounting tube 141 and a threaded sleeve 142. The mounting tube 141 is arranged in a cylindrical shape, extending along the height direction of the vehicle body, and passing through the upper wall 101 and the lower wall 102 of the cargo box cross beam 10. The mounting tube 141 is made of aluminum alloy and is fixed to the upper wall 101 by arc welding. The threaded sleeve 142 is located in the mounting tube 141 and is arranged near the lower part of the mounting tube 141. The threaded sleeve 142 is made of steel and has an interference fit with the mounting tube 141.

[0044] The fastener 60 passes through the frame 70 and the lower wall 102 from bottom to top, extends into the mounting tube 141, and cooperates with the threaded sleeve 142 to realize the connection between the frame 70 and the cargo box cross beam 10. By arranging the mounting portion 14 in the cargo box cross beam 10 and connecting the mounting portion 14 with the frame 70, a high-torque connection between the cargo box cross beam 10 and the frame 70 can be realized, ensuring the connection strength between the cargo box frame and the frame 70, ensuring the structural reliability of the vehicle, and improving the rigidity and deformation resistance of the whole vehicle. At the same time, the design of the mounting portion 14 can facilitate the mass production and assembly of the cargo box frame, which is conducive to reducing manufacturing costs.

[0045] Specifically, the frame 70 includes a pair of frame longitudinal beams 71 and a plurality of frame cross beams 72. A total of four mounting portions 14 are provided on the first cross beam 11 of the cargo box to be fixed to the frame longitudinal beams 71. A total of two mounting portions 14 are provided on the second cross beam 12 of the cargo box to be fixed to the frame longitudinal beams 71. A total of four mounting portions 14 are provided on the third cross beam 13 of the cargo box to be fixed to the frame cross beam 72 at the rear end.

[0046] The present application also provides a vehicle, including a frame 70 and the cargo box frame as described above, wherein the frame 70 is located at the bottom of the cargo box frame, and the frame 70 and the cargo box cross beam 10 are connected by fasteners 60.

[0047] The cargo box frame and vehicle of the present application form a skeleton frame structure by arranging cargo box vertical beams 20 at both ends of the cargo box cross beam 10, and fixing the upper end of the cargo box vertical beam 20 to the upper side beam 30, thereby improving the bending rigidity and torsional rigidity of the cargo box frame and having good structural stability. The cargo box cross beam 10 and the cargo box vertical beam 20 are fixed by arranging a connecting piece 40, thereby improving the connection strength of the cargo box frame.

[0048] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
