[0029] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0030] Reference below Figure 1-Figure 4 The vehicle frame assembly 100 according to the embodiment of the present invention is described, which can improve the overall bending and torsion resistance of the power battery 200 and can also increase the connection strength between the vehicle frame assembly 100 and the power battery 200.

[0031] Combination Figure 1-Figure 4 As shown, the vehicle frame assembly 100 according to the first embodiment of the utility model comprises a vehicle frame 1, a mounting crossbeam 2 and at least two mounting brackets 3. The mounting crossbeam 2 and the at least two mounting brackets 3 are both mounted on the vehicle frame 1.

[0032] Specifically, the frame 1 includes a longitudinal beam 11 and multiple cross beams 12, the multiple cross beams 12 are respectively connected between two opposite longitudinal beams 11, and the multiple cross beams 12 are spaced apart in the longitudinal direction, the mounting cross beam 2 is connected between the two opposite longitudinal beams 11, and the mounting cross beam 2 is spaced apart from the multiple cross beams 12, a first battery pack mounting point 21 is provided on the mounting cross beam 2, at least two mounting brackets 3 are provided on a cross beam 12 located behind the mounting cross beam 2, and at least two mounting brackets 3 are spaced apart in the transverse direction (that is, left and right direction) on the cross beam 12, each mounting bracket 3 is provided with a second battery pack mounting point 31, and the first battery pack mounting point 21 and the second battery pack mounting point 31 are used to install the power battery 200.

[0033] The left and right ends of the plurality of cross beams 12 are respectively connected to the two opposite longitudinal beams 11 , and the plurality of cross beams 12 are spaced apart in the front-rear direction, so that the plurality of cross beams 12 and the two longitudinal beams 11 form a force-stable frame structure.

[0034] In addition, the left and right ends of the mounting crossbeam 2 are also connected to the two opposite longitudinal beams 11, so that a stable connection relationship between the mounting crossbeam 2 and the frame 1 can be established, and a first battery pack 200 decoration point for mounting and fixing the power battery 200 is provided on the mounting crossbeam 2, and at least two mounting brackets 3 on the crossbeam 12 located behind the mounting crossbeam 2 are spaced apart along the transverse direction (that is, the left and right direction), and each mounting bracket 3 is provided with a second battery pack mounting point 31 for mounting and fixing the power battery 200, so that a special mounting connection structure can be formed for the power battery 200 through the first battery pack mounting point 21 on the front mounting crossbeam 2 and the second battery pack mounting point 31 on the rear mounting bracket 3, thereby enhancing the overall bending and torsional resistance of the power battery 200 and the connection strength between the power battery 200 and the frame 1 bracket.

[0035] In particular, compared to the traditional frame assembly (the power battery is only directly installed on the vehicle body floor or connected to the vehicle body floor through a simple bracket), the embodiment in this case adds a dedicated mounting beam 2 at the front end of the battery pack 200 and sets a mounting bracket 3 on the beam 12 at the rear end of the battery pack 200 to form a fixed mounting point specifically for the power battery 200. This can effectively increase the bending and torsional resistance of the overall structure of the power battery 200, and can also increase the connection strength between the frame assembly 100 and the power battery 200, thereby effectively improving the durability of the frame assembly 100 and the power battery 200 and avoiding the problem of cracking in the later stage.

[0036] Therefore, by setting up the frame assembly 100, the overall bending and torsion resistance of the power battery 200 can be improved, and the connection strength between the frame assembly 100 and the power battery 200 can be increased, thereby effectively improving the durability of the frame assembly 100 and the power battery 200 and avoiding the problem of cracking in the later stage.

[0037] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 4 As shown, the vehicle frame assembly 100 further includes a connecting bracket 4, which is disposed on the longitudinal beam 11, and the end of the mounting crossbeam 2 is connected to the connecting bracket 4. In the left-right direction, the connecting bracket 4 is connected between the end of the mounting crossbeam 2 and the longitudinal beam 11, so that the mounting crossbeam 2 can establish an indirect connection relationship with the longitudinal beam 11 through the connecting bracket 4, thereby increasing the structural strength and bending and torsional rigidity of the mounting crossbeam 2, and further improving the structural reliability of the mounting crossbeam 2.

[0038] Specifically, combined Figure 1 and Figure 4 As shown, the connecting bracket 4 includes a plurality of side panels 41 and a top panel 42 connected in sequence, the bottoms of the plurality of side panels 41 are connected to the longitudinal beam 11, the tops of the plurality of side panels 41 are connected to the top panel 42, the end of the mounting beam 2 is connected to the top panel 42, and the plurality of side panels 41, the top panel 42 and the longitudinal beam 11 together form a first cavity 43.

[0039] It can be understood that the bottoms of the multiple side panels 41 are connected to the upper end surface of the longitudinal beam 11, the top panel 42 is connected to the tops of the multiple side panels 41, and the top panel 42 is bent relative to the side panels 41, so that the multiple side panels 41, the top panel 42 and the longitudinal beam 11 can jointly define a first cavity 43, so that a connecting bracket 4 with a closed cavity can be constructed, which can effectively enhance the structural stability of the mounting beam 2 near the root of one end of the longitudinal beam 11 (here is the force concentration area where an indirect connection relationship is established between the mounting beam 2 and the longitudinal beam 11), thereby improving the structural reliability of the mounting beam 2.

[0040] Optionally, the welding connection has the advantages of high connection strength and good sealing performance, so the side panel 41 and the longitudinal beam 11 are connected by welding, which can effectively ensure the connection reliability between the side panel 41 and the longitudinal beam 11.

[0041] Alternatively, the end of the mounting beam 2 is connected to the top plate 42 by fasteners. Compared with other connection methods, such as bonding, clamping, etc., the fastener connection method can be easy to install and disassemble, and can also have better connection strength, thereby improving assembly flexibility.

[0042] According to some optional embodiments of the present invention, combined with Figure 1As shown, at least two mounting brackets 3 include a first mounting bracket 5 and a second mounting bracket 6 , the rear end of the first mounting bracket 5 is arranged on the top of the cross beam 12 , and the rear end of the second mounting bracket 6 is arranged on the front side of the cross beam 12 .

[0043] For example, the rear end of the first mounting bracket 5 can be set on the top of the beam 12 at the rear end of the power battery 200, and the rear end of the second mounting bracket 6 can be set on the front side of the beam 12. In this way, a connection relationship can be established with the mounting bracket 3 on different side surfaces of the beam 12, avoiding stress concentration on the same side surface of the beam 12, thereby making the force on the beam 12 more uniform, thereby improving the structural durability of the beam 12.

[0044] Specifically, combined Figure 1-Figure 3 As shown, the second mounting bracket 6 includes a first bracket 61 and a second bracket 62. The rear end of the first bracket 61 is arranged on the front side of the cross beam 12, and the second bracket 62 is arranged on the first bracket 61. The second bracket 62 extends forward, and the second bracket 62 is provided with a second battery pack mounting point 31.

[0045] It can be understood that in order to avoid the problem that the second mounting bracket 6 is subjected to severe stress and easy cracking due to the force arm being too long, in the front-to-back direction, the rear end of the first bracket 61 is connected to the front side of the crossbeam 12, and the rear end of the second bracket 62 is connected to the front end of the first bracket 61, and the second bracket 62 continues to extend forward, and a second battery pack mounting point 31 for mounting and fixing the power battery 200 is provided at the front end of the second bracket 62. Such an arrangement can achieve the effect of shortening the force arm to reduce the stress by adopting the design of a split connection structure of the first bracket 61 and the second bracket 62, thereby improving the durability of the second mounting bracket 6 and the power battery 200.

[0046] Furthermore, combined with Figure 1 and Figure 2 As shown, the second bracket 62 includes a first extension section 621 and a second extension section 622. The first extension section 621 is provided with a second battery pack mounting point 31. The second extension section 622 is connected to the rear side of the first extension section 621. The second extension section 622 is bent relative to the first extension section 621. The end of the second extension section 622 away from the first extension section 621 is connected to the first bracket 61.

[0047] Among them, a second battery pack installation point 31 is set on the front side of the first extension section 621, and the rear side of the first extension section 621 is connected to the front side of the second extension section 622. The second extension section 622 is bent relative to the first extension section 621. In this way, the original path extension direction of the first extension section 621 can be changed, so that it is convenient to match the extension path according to the position of the first bracket 61 to which the rear end of the second extension section 622 is to be connected, thereby improving the rationality of its layout.

[0048] Specifically, combined Figure 1 and Figure 3 As shown, the second bracket 62 includes an upper plate 623 and a lower plate 624, upper plate 623 is provided with upper flanges 6231 on both lateral sides, the lower plate 624 is arranged opposite to the upper plate 623 in the up and down directions, lower flanges 6241 are provided on both lateral sides of the lower plate 624, the upper flanges 6231 are connected to the lower flanges 6241, and the lower plate 624 is connected to the first bracket 61.

[0049] It can be understood that in the up and down directions, the upper plate 623 and the lower plate 624 of the second bracket 62 are arranged opposite to each other, and the upper plate 623 is provided with upper flanges 6231 bent toward the bottom on both lateral sides, and the lower plate 624 is provided with lower flanges 6241 bent toward the top on both lateral sides. The upper plate 623 and the lower plate 624 are connected as a whole through the upper flanges 6231 and the lower flanges 6241, and the lower surface of the lower plate 624 is connected to the upper surface of the first bracket 61. In this way, the above structures are connected in sequence from top to bottom to finally achieve the split connection effect of the second bracket 62 and the first bracket 61, thereby achieving the effect of shortening the force arm (compared with the force arm length of the integrated bracket) to reduce the force, thereby improving the structural durability of the second mounting bracket 6.

[0050] In addition, the second bracket 62 can be connected to the first bracket 61 by snapping and welding the upper plate 623 and the lower plate 624, so that a cavity can be formed, thereby effectively improving the structural stability of the upper root of the second bracket 62 (that is, the connection and installation place of the second bracket 62 and the first bracket 61 and the power battery 200).

[0051] Furthermore, combined with Figure 1 and Figure 2 As shown, a first mounting sleeve 625 is provided at the rear end of the second bracket 62, and a second mounting sleeve 626 is provided at the front end of the second bracket 62. The second bracket 62 is connected to the first bracket 61 through the first mounting sleeve 625, and the second mounting sleeve 626 constitutes a second battery pack mounting point 31.

[0052] Among them, the front end and the rear end of the second bracket 62 are respectively provided with a second mounting sleeve 626 and a first mounting sleeve 625. The second bracket 62 is connected to the first bracket 61 through the first mounting sleeve 625 at its rear end, and the second bracket 62 is connected to the power battery 200 through the second mounting sleeve 626 at its front end. Since the mounting sleeve can strengthen the structural strength at the installation connection point, such an arrangement is conducive to improving the durability of the connection between the second bracket 62 and the first bracket 61 and the second battery pack installation point 31, thereby improving the connection reliability.

[0053] According to the embodiment of the second aspect of the utility model, the vehicle includes a battery pack 200 and the frame assembly 100 of the above embodiment. The vehicle having the frame assembly 100 can enhance the structural strength at the installation point of the battery pack 200, thereby reducing the load borne by the battery pack 200, thereby improving the durability of the frame assembly 100 and the power battery 200, and avoiding the problem of cracking in the later stage.
