[0029] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0030] like Figures 1 to 6As shown, this embodiment provides a vehicle body structure, including: a frame structure 1 and an airbag. The frame structure 1 includes a subframe and a lower body 11. The subframe is connected to the lower body 11. The lower body 11 includes a first longitudinal beam 111, a second longitudinal beam 112, and a crossbeam 113. The first longitudinal beam 111 and the second longitudinal beam 112 are spaced apart along the width direction y of the frame structure. The crossbeam 113 is located between the first longitudinal beam 111 and the second longitudinal beam 112 and is connected to the first longitudinal beam 111 and the second longitudinal beam 112. The airbag is connected to the frame structure 1. The crossbeam 113 has an air storage chamber 101, which communicates with the airbag.

[0031] In this embodiment, the vehicle body structure also includes a rear bumper beam 6, which is connected to the first longitudinal beam 111 and the second longitudinal beam 112. The subframe and the rear bumper beam 6 are spaced apart along the length x of the vehicle frame structure, and the subframe is connected to the first longitudinal beam 111 and the second longitudinal beam 112 to ensure the rigidity of the entire vehicle.

[0032] For other structures of the subframe, please refer to existing technology; they will not be elaborated here.

[0033] In this embodiment, the airbag is an air spring airbag, and the air spring is connected to the subframe via a swing arm. When the air spring needs to extend, the gas in the air storage chamber 101 can be injected into the airbag; when the air spring needs to contract, the gas in the airbag can be extracted into the air storage chamber 101.

[0034] In this embodiment, since the crossbeam 113 has an air storage chamber 101 that communicates with the airbag, the air storage chamber 101 of the crossbeam 113 can inflate or depress the airbag of the air spring to achieve the extension or compression of the air spring. Therefore, the vehicle body structure of this application integrates the air storage function of the air spring tank into the crossbeam 113, eliminating the need for additional air spring tanks and air spring tank fixing brackets, which helps save space in the lower body 11 or passenger compartment, reduce the weight of the entire vehicle, and improve the overall aesthetics of the vehicle.

[0035] Combination Figure 1 and Figure 3 As shown, the lower body 11 also includes a rear floor 114, which is connected to the first longitudinal beam 111, the second longitudinal beam 112 and the crossbeam 113. The rear floor 114 includes a rear luggage compartment area 103, and the orthographic projection of the crossbeam 113 along the height direction z of the frame structure on the rear floor 114 is located within the rear luggage compartment area 103.

[0036] It should be understood that the length direction (x), width direction (y), and height direction (z) of the frame structure are all bidirectional.

[0037] In this embodiment, the crossbeam 113 connects the first longitudinal beam 111 and the second longitudinal beam 112, and the rear floor 114 is connected to the first longitudinal beam 111, the second longitudinal beam 112, and the crossbeam 113, which helps to improve the strength of the lower body 11. Furthermore, since the orthographic projection of the crossbeam 113 along the height z direction of the frame structure on the rear floor 114 is located within the rear luggage compartment area 103, the crossbeam 113 can strengthen and support the rear luggage compartment area 103 to ensure the load-bearing capacity of the rear luggage compartment area 103.

[0038] In this embodiment, combined with Figure 1 , Figure 2 and Figure 6 As shown, the vehicle body structure also includes an air pump 2, which is connected to the first longitudinal beam 111 and communicates with the air storage chamber 101 and the airbag. The air pump 2 is used to inflate or deflate the airbag of the air spring, thereby adjusting the vehicle height and suspension stiffness.

[0039] It should be understood that after the air pump 2 is connected to the air spring's air bladder, when the air spring needs to extend, the air pump 2 will fill the air spring's air bladder with gas from the air storage chamber 101; when the air spring needs to contract, the air pump 2 will extract the gas from the air spring's air bladder into the air storage chamber 101.

[0040] In other embodiments, the air pump 2 may also be connected to the second longitudinal beam 112.

[0041] In this embodiment, the crossbeam 113 is provided with an air port 102, which connects the inside and outside of the air storage chamber 101. The frame structure 1 also includes an air pipe 3, one end of which is connected to the air port 102, and the other end of which is connected to the air pump 2. The air pipe 3 is used to connect the air pump 2 to the air storage chamber 101 to ensure that gas can flow between the airbag and the air storage chamber 101.

[0042] Combination Figures 1 to 3 As shown, the orthographic projection of the air pump 2 along the height direction z of the frame structure onto the rear floor 114 is located within the rear luggage compartment area 103.

[0043] In this embodiment, the first longitudinal beam 111 is provided with an air pump mounting area 104 for mounting the air pump 2, and the air pump mounting area 104 is disposed below the rear trunk area 103. The air pump 2 and the crossbeam 113 are both disposed in the rear trunk area 103 to facilitate communication between the air pump 2 and the air storage chamber 101 of the crossbeam 113, thereby facilitating the inflation or deflation of the airbag.

[0044] In this embodiment, the crossbeam 113 and the subframe are spaced apart along the length x of the frame structure, and the air pump 2 is also spaced apart along the length x of the frame structure. Both the crossbeam 113 and the air pump 2 are spaced apart from the subframe to avoid interference with its installation, thus preventing their arrangement from affecting the subframe's installation.

[0045] Combination Figure 3 As shown, both the first longitudinal beam 111 and the second longitudinal beam 112 are provided with a subframe mounting area 105 for mounting the subframe. Along the length direction x of the frame structure, the subframe mounting area 105 is closer to the driver's seat than the air pump mounting area 104.

[0046] Combination Figure 4 As shown, the vehicle body structure also includes a first mounting bracket 41 and a second mounting bracket 42. The first mounting bracket 41 is detachably connected to the first longitudinal beam 111 via a first fastener 51, and the second mounting bracket 42 is detachably connected to the second longitudinal beam 112 via a first fastener 51. The crossbeam 113 is connected to the first mounting bracket 41 and the second mounting bracket 42.

[0047] Combination Figure 1 and Figure 5 As shown, both the first longitudinal beam 111 and the second longitudinal beam 112 include a beam body 111a, a first ear plate 111b, and a second ear plate 111c. The first ear plate 111b and the second ear plate 111c are connected one-to-one to the two opposite sides of the beam body 111a along the width direction y of the frame structure.

[0048] In this embodiment, the first mounting bracket 41 and the second mounting bracket 42 are "Z-shaped structures" of the same size and shape. Both the first mounting bracket 41 and the second mounting bracket 42 include a first mounting part 411, a connecting part 412 and a second mounting part 413. The connecting part 412 connects the first mounting part 411 and the second mounting part 413. The first mounting part 411 of the first mounting bracket 41 is detachably connected to the beam body part 111a of the first longitudinal beam 111 by two first fasteners 51. The first mounting part 411 of the second mounting bracket 42 is detachably connected to the beam body part 111a of the second longitudinal beam 112 by two first fasteners 51. The crossbeam 113 is connected to the second mounting part 413 of the first mounting bracket 41 and the second mounting part 413 of the second mounting bracket 42 by welding.

[0049] In this embodiment, the crossbeam 113 is connected to the first longitudinal beam 111 via the first mounting bracket 41 and to the second longitudinal beam 112 via the second mounting bracket 42, which helps to improve the strength of the vehicle body structure. Furthermore, the first mounting portion 411 of the first mounting bracket 41 is detachably connected to the beam body portion 111a of the first longitudinal beam 111 via a first fastener 51, and the first mounting portion 411 of the second mounting bracket 42 is detachably connected to the beam body portion 111a of the second longitudinal beam 112 via a first fastener 51, facilitating the disassembly and replacement of the crossbeam 113.

[0050] It should be understood that the number of the first fastener 51 can be selected according to the actual situation.

[0051] Combination Figure 4 and Figure 5 As shown, the first ear plate 111b of the first longitudinal beam 111 is disposed opposite to the first mounting bracket 41 along the height direction z of the frame structure, and a first limiting groove 401 is provided between the first mounting bracket 41 and the first mounting bracket 41; the first ear plate 111b of the second longitudinal beam 112 is disposed opposite to the second mounting bracket 42 along the height direction z of the frame structure, and a second limiting groove is provided between the second mounting bracket 42 and the second mounting bracket 42; the crossbeam 113 is located in the first limiting groove 401 and the second limiting groove, and the crossbeam 113 is detachably connected to the first ear plate 111b by the second fastener 52.

[0052] In this embodiment, the crossbeam 113 includes an air storage section 1131a, a first connecting section 1131b, and a second connecting section. The first connecting section 1131b and the second connecting section are connected along the width direction y of the frame structure to two opposite sides of the air storage section 1131a. The air storage chamber 101 is located inside the air storage section 1131a. The first ear plate 111b of the first longitudinal beam 111 is connected to the first connecting section 1131b by a second fastener 52, and the first ear plate 111b of the second longitudinal beam 112 is connected to the second connecting section by a second fastener 52, so as to avoid the air storage section 1131a being connected to the first ear plate 111b and thus affecting the sealing of the air storage chamber 101.

[0053] In this embodiment, the first connecting part 1131b is located in the first limiting groove 401 and is connected between the first ear plate 111b of the first longitudinal beam 111 and the second mounting part 413 to ensure the connection strength between the cross beam 113 and the first longitudinal beam 111, thereby ensuring the strength of the lower vehicle body 11; the second connecting part is located in the second limiting groove and is connected between the first ear plate 111b of the second longitudinal beam 112 and the second mounting part 413 to ensure the connection strength between the cross beam 113 and the second longitudinal beam 112, thereby ensuring the strength of the lower vehicle body 11.

[0054] In addition, the first connecting part 1131b is detachably connected to the first ear plate 111b of the first longitudinal beam 111 via the second fastener 52, and the second connecting part is detachably connected to the first ear plate 111b of the second longitudinal beam 112 via the second fastener 52, so as to facilitate the disassembly and replacement of the crossbeam 113.

[0055] It should be understood that the number of the second fastener 52 can be selected according to the actual situation.

[0056] For example, the number of second fasteners 52 can be selected based on the width of the crossbeam 113 (the length along the length direction x of the frame structure).

[0057] Combination Figures 3 to 6 As shown, the crossbeam 113 includes a main beam portion 1131, a first flange 1132, and a second flange 1133. The main beam portion 1131 includes an air storage portion 1131a, a first connecting portion 1131b, and a second connecting portion. The air storage chamber 101 is located in the air storage portion 1131a. The first flange 1132 and the second flange 1133 are connected to two opposite sides of the main beam portion 1131 along the length direction x of the frame structure. The first flange 1132 and the second flange 1133 are detachably connected to the rear floor 114 by a third fastener 53.

[0058] In this embodiment, the rear floor 114 includes a first floor 1141 and a second floor 1142. The first floor 1141 and the second floor 1142 are spaced apart from each other along the length x of the vehicle frame structure. The first floor 1141 is closer to the rear bumper beam 6 than the second floor 1142. The first flange 1132 is connected to the first floor 1141 by four third fasteners 53, and the second flange 1133 is connected to the second floor 1142 by four third fasteners 53. This avoids affecting the sealing of the air storage chamber 101 due to the connection between the main beam 1131 and the rear floor 114, thereby preventing the main beam 1131 from losing its air storage function.

[0059] In addition, the first flange 1132 is detachably connected to the first floor 1141 by four third fasteners 53, and the second flange 1133 is detachably connected to the second floor 1142 by four third fasteners 53, so as to facilitate the disassembly and replacement of the crossbeam 113.

[0060] It should be understood that the number of the third fastener 53 can be selected according to the actual situation.

[0061] For example, the number of third fasteners 53 can be selected based on the length of the crossbeam 113 (the length along the width direction y of the frame structure).

[0062] For example, the first fastener 51, the second fastener 52 and the third fastener 53 may be bolts or screws, etc.

[0063] In this embodiment, the vehicle body structure further includes a first sealing structure, a second sealing structure, and a third sealing structure. The first sealing structure is connected between the first ear plate 111b and the first connecting portion 1131b to seal the connection between the first ear plate 111b and the first connecting portion 1131b. The second sealing structure is connected between the first flange 1132 and the first floor 1141 to seal the connection between the first flange 1132 and the rear floor 114. The third sealing structure is connected between the second flange 1133 and the second floor 1142 to seal the connection between the second flange 1133 and the rear floor 114.

[0064] In this embodiment, the first sealing structure, the second sealing structure, and the third sealing structure are all used to isolate the inside and outside of the vehicle. The first sealing structure, the second sealing structure, and the third sealing structure can not only reduce noise, but also block dust, rainwater, and pollutants.

[0065] Specifically, the first sealing structure, the second sealing structure, and the third sealing structure all include a sealing strip and sealant. The sealing strip of the first sealing structure is connected between the first ear plate 111b and the first connecting part 1131b. After the second fastener 52 is connected to the first ear plate 111b and the first connecting part 1131b, the gap is filled with sealant to further improve the sealing effect. The sealing strip of the second sealing structure is connected between the first flange 1132 and the first floor 1141. After the third fastener 53 is connected to the first flange 1132 and the first floor 1141, the gap is filled with sealant to further improve the sealing effect. The sealing strip of the third sealing structure is connected between the second flange 1133 and the second floor 1142. After the third fastener 53 is connected to the second flange 1133 and the second floor 1142, the gap is filled with sealant to further improve the sealing effect.
