[0038] Combination Figure 1 and Figure 3 As shown, the panel 2 can be formed as an integral aluminum panel, covered on the frame 1, and fixedly connected to the frame 1 by welding. Figure 1 and Figure 2 As shown, two (i.e. a pair) first support seats 11 are arranged at intervals along the width direction of the vehicle body, one second support seat 12 is located on the left side of the two first support seats 11, and the other second support seat 12 is located on the right side of the two first support seats 11, and the two second support seats 12 are arranged symmetrically with the longitudinal axis of the vehicle body, a first cross beam 13 is provided in the interval between the two first support seats 11, and the two first support seats 11 are respectively welded to the two ends of the first cross beam 13, and a second cross beam 14 and a third cross beam 15 arranged at intervals along the length direction of the vehicle body are provided between adjacent first support seats 11 and second support seats 12, from front to back, they are the second cross beam 14 and the third cross beam 15, both ends of the second cross beam 14 are respectively welded to the adjacent first support seats 11 and the second support seats 12, and both ends of the third cross beam 15 are respectively welded to the adjacent first support seats 11 and the second support seats 12, and the first support seat 11, the second cross beam 14, the second support seat 12 and the third cross beam 15 form a closed-loop frame structure (i.e. a closed ring-shaped frame structure).

[0039] Exemplarily, multiple pairs of second support seats 12 can be provided and symmetrically arranged on both sides of the two first support seats 11, and a second cross beam 14 and a third cross beam 15 are arranged between the two second support seats 12 along the length direction of the vehicle body (this embodiment is not shown in the figure).

[0040] Exemplarily, the frame 1 and the panel 2 in the present invention are both made of aluminum, wherein the first support seat 11, the second support seat 12, the first crossbeam 13, the second crossbeam 14 and the third crossbeam 15 are made of aluminum alloy extrusion process, and the first crossbeam 13, the second crossbeam 14 and the third crossbeam 15 can adopt a Japanese-shaped cross-section beam, which is beneficial to the lightweight design of the rear seat skeleton structure and has good energy absorption performance.

[0041] The rear seat skeleton structure of the present invention is arranged by two first support seats 11 spaced apart along the width direction of the vehicle body, and the second support seats 12 are arranged on both sides of the two first support seats 11. The two first support seats 11 are connected by a first cross beam 13, and the first support seat 11 and the second support seat 12 are connected by a second cross beam 14 and a third cross beam 15 spaced apart along the length direction of the vehicle body, and a closed-loop frame structure is formed, so that the parts on both sides of the rear seat skeleton structure have better energy absorption and transmission capabilities, while ensuring the lightweight of the overall structure, the strength performance of the overall structure is also guaranteed. When using materials such as aluminum, the rear seat skeleton structure of the present invention can better play the advantages of the lightweight and good strength performance of aluminum materials, and has high feasibility.

[0042] Furthermore, the first support seat 11 and the second support seat 12 are provided with a plurality of closed-loop through holes 10 opened along the width direction of the vehicle body.

[0043] Combination Figure 4 and Figure 5 As shown, the direction perpendicular to the drawing is the width direction of the vehicle body, that is, Figures 1 to 3 In the X-axis direction shown in the figure, the multiple closed-loop through holes 10 on the first support seat 11 exemplarily adopt structures such as rectangular holes and / or triangular holes, extending in the width direction of the vehicle body and passing through the first support seat 11, and the closed-loop through holes 10 on the second support seat 12 can adopt a similar hole structure design, or a different hole structure design, such as a polygonal hole and / or a circular hole. However, it should be understood that in order to ensure the structural strength of the first support seat 11 and the second support seat 12, the closed-loop through holes 10 should be a closed-loop shaped hole structure.

[0044] In this way, by opening a plurality of closed-loop through holes 10 , it is possible to improve the structural strength performance while achieving a lightweight structural design, thereby better realizing the energy absorption and transmission of force.

[0045] Preferably, the ends of the first beam 13, the second beam 14, and the third beam 15 are inserted into the closed-loop through holes 10 at corresponding positions, so that the two ends of the first beam 13 are insert-welded to the two first support seats 11, and the two ends of the second beam 14 and the two ends of the third beam 15 are insert-welded to the first support seat 11 and the second support seat 12 at corresponding positions, which can avoid the problem of cracking caused by insufficient strength of the welding structure and has good structural strength performance.

[0046] Furthermore, the first support seat 11 is provided with a plurality of first connection holes spaced apart along the length direction of the vehicle body, the second support seat 12 is provided with a plurality of second connection holes spaced apart along the length direction of the vehicle body, the first support seat 11 is provided with a first cylindrical member 111 corresponding to the first connection holes, and the second support seat 12 is provided with a second cylindrical member 121 corresponding to the second connection holes.

[0047] Combination Figure 2 As shown, two first connecting holes are spaced apart on the first supporting seat 11 along the Y-axis direction in the figure, and a first cylindrical member 111 is provided at a position corresponding to the first connecting holes, and two second connecting holes are spaced apart on the second supporting seat 12 along the Y-axis direction in the figure, and a second cylindrical member 121 is provided at a position corresponding to the second connecting holes, the first cylindrical member 111 is located in the closed-loop through hole 10 at the corresponding position and is welded and fixed to the side wall of the closed-loop through hole 10, and the second cylindrical member 121 is located in the closed-loop through hole 10 at the corresponding position and is welded and fixed to the side wall of the closed-loop through hole 10.

[0048] In this way, when installing the first support seat 11 and the second support seat 12, connecting parts such as bolts can pass through the first cylindrical member 111 and the second cylindrical member 121, which on the one hand has installation guidance, and on the other hand can improve the structural strength, rigidity and wear resistance of the installation point after installation.

[0049] Furthermore, the third cross beam 15 is provided with a first support member 151 extending toward the rear of the vehicle, and the panel 2 is covered and connected to the third cross beam 15 and the first support member 151; the cross section of the first support member 151 is a U-shaped structure.

[0050] Combination Figure 1 and Figure 2 As shown, one end of the first support member 151 is welded to the third cross beam 15, and the other end extends toward the rear of the vehicle (i.e., in the opposite direction of the Y axis). The panel 2 covers the third cross beam 15 and the first support member 151 and is welded and fixed. Optionally, Figure 6 As shown, the cross-section of the first support member 151 adopts a U-shaped structure to improve its force-bearing performance and weight-reducing performance.

[0051] In this way, the first support member 151 can provide better support for the seats arranged at the corresponding positions on the panel 2, so as to improve the overall supporting performance of the rear seat skeleton structure.

[0052] Furthermore, the frame 1 also includes a fourth cross beam 16, which is spaced apart from the first cross beam 13 along the length direction of the vehicle body, and both ends of the first cross beam 13 and the fourth cross beam 16 are respectively connected to two adjacent first support seats 11 to form a closed-loop frame structure.

[0053] Combination Figure 1 and Figure 2 As shown, both ends of the fourth cross beam 16 are respectively welded to the two first support seats 11, and the fourth cross beam 16 and the first cross beam 13 are spaced apart along the length direction of the vehicle body, and the fourth cross beam 16 is arranged at the front, and the first cross beam 13 is arranged at the rear, forming a structure in which the fourth cross beam 16 and the first cross beam 13 are arranged in sequence from front to rear, and form a closed-loop frame structure with the two first support seats 11.

[0054] In this way, a plurality of closed-loop frame structures are formed by the closed-loop frame structure formed by the first cross beam 13, the fourth cross beam 16 and the two first support seats 11, and the closed-loop frame structure formed by the second cross beam 14, the third cross beam 15, the first support seat 11 and the second support seat 12, thereby ensuring the overall structural performance and strength of the rear seat skeleton structure, and better realizing the energy absorption and transmission of force, thereby meeting the vehicle structural performance requirements.

[0055] Preferably, the fourth cross beam 16 is an arched beam, and the panel 2 is covered and connected to the arched beam. Figure 1 and Figure 2 As shown, the fourth cross beam 16 is an arched beam arched upward (and in the positive direction of the Z axis in the figure), and its two ends are respectively welded to the two first support seats 11. The panel 2 covers the upper end surface of the fourth cross beam 16 and is welded and fixed to support the middle part of the rear seat and avoid other parts of the vehicle structure located below it, which is beneficial to the spatial layout design of the corresponding components.

[0056] Furthermore, the first cross beam 13 is provided with a second support member 131 extending toward the rear of the vehicle, and the panel 2 is covered and connected to the second support member 131; the cross section of the second support member 131 is a U-shaped structure.

[0057] Combination Figure 1 and Figure 2 As shown, one end of the second support member 131 is welded to the first crossbeam 13, and the other end extends toward the rear of the vehicle (ie, toward the opposite direction of the Y axis in the figure). The panel 2 covers the second support member 131 and is welded and fixed. Optionally, Figure 7 As shown, the cross section of the second support member 131 is a U-shaped structure.

[0058] In this way, the second support member 131 can provide better support for the seats arranged at the corresponding positions on the panel 2, so as to improve the overall supporting performance of the rear seat skeleton structure.

[0059] Furthermore, a first seat cushion connection portion 21 is provided on the side of the panel 2 close to the front of the vehicle, a third support member 141 extending toward the first seat cushion connection portion 21 is provided on the second cross beam 14, and the panel 2 is covered and connected to the second cross beam 14 and the third support member 141; the cross-section of the third support member 141 is a U-shaped structure.

[0060] Combination Figure 2 and Figure 3 As shown, the first cushion connection part 21 is a plate-like structure, which is installed on the end surface of the panel 2 away from the frame 1 and is used to connect with the cushion part of the seat. One end of the third support member 141 is welded to the second cross beam 14, and the other end extends toward the first cushion connection part 21 and is welded to the corresponding position on the panel 2. Optionally, in combination with Figure 8 As shown, the cross section of the third support member 141 is a U-shaped structure.

[0061] In this way, the seat cushion can be better connected and fixed through the first seat cushion connecting part 21, and the third support member 141 can provide better support for the seat arranged at the corresponding position on the panel 2, so as to improve the overall supporting performance of the rear seat skeleton structure.

[0062] Furthermore, a second cushion connection portion 122 is provided on the second support seat 12 , and a through hole 22 is provided on the panel 2 corresponding to the second cushion connection portion 122 to accommodate the second cushion connection portion 122 passing therethrough.

[0063] Combination Figures 1 to 3 As shown, the second cushion connection part 122 is welded and fixed on the second support seat 12, and the panel 2 is correspondingly provided with a through hole 22. When the frame 1 and the panel 2 are installed with each other, the second cushion connection part 122 passes through the through hole 22 to be connected with the cushion part of the seat. Fig. 9 As shown, the second cushion connection portion 122 is an L-shaped structure as a whole, one end of which can be welded to the second support seat 12, and the other end is provided with a hook structure for clamping with the relevant structure of the cushion part.

[0064] In this way, by setting the through hole 22, it is convenient for the second cushion connection part 122 to pass through the panel 2 and connect with the cushion part. The second cushion connection part 122 can be used to better connect and fix the cushion to improve the overall supporting performance of the rear seat skeleton structure.
