[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on June 29, 2023, with application number 202310788057.1, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The embodiments of the present application relate to, but are not limited to, the field of automobile manufacturing technology, and in particular relate to, but are not limited to, a vehicle body structure and a vehicle. Background Art

[0004] With the development of technology, vehicles are appearing more and more in people's lives, and people's requirements for vehicles are getting higher and higher.

[0005] Summary of the Invention

[0006] The following is a summary of the subject matter described in detail herein. This summary is not intended to limit the scope of the claims.

[0007] According to a first aspect of an embodiment of the present application, a vehicle body structure is provided, comprising: a longitudinal beam, a cross beam, a trunk, an air tank, an air pump and a rear suspension; wherein the longitudinal beam and the cross beam are connected to each other, and the longitudinal beam extends into the trunk; the air pump is connected to the longitudinal beam extending into the trunk; the air pump and the air tank are arranged on both sides of the central axis of the vehicle body structure, and are located close to the rear suspension.

[0008] This arrangement effectively reduces vibrations when they reach the longitudinal beams, effectively blocking most of them. Therefore, connecting the air pump to the longitudinal beams can partially block the vibrations generated by the air pump, thereby reducing the impact of the air pump's vibrations on the vehicle body structure, thereby improving the vehicle's ride quality and the stability of other systems.

[0009] Moreover, by arranging the air pump and the air tank on both sides of the central axis of the vehicle body structure, the space occupied by the air pump and the air tank in the length direction of the vehicle is shortened, so that the air pump and the air tank arranged in this way can adapt to various rear overhang lengths, that is, the length from the center of the rear wheel to the rear of the vehicle. Furthermore, the vehicle models that can be adapted to the above-mentioned air pump and air tank arrangement scheme can be expanded.

[0010] In some embodiments, the trunk also includes an expansion floor and a rear panel; the rear panel is connected to one end of the longitudinal beam; in the area enclosed by the longitudinal beam, the cross beam and the rear panel, the lower surfaces of the longitudinal beam, the cross beam and the rear panel are connected to the expansion floor and are flush with each other; the recessed structure formed by extending the expansion floor downward is used as an expansion portion; the air pump and the air tank are located on both sides of the expansion portion along the central axis.

[0011] This arrangement minimizes the number of structures that might interfere with the expansion portion, as the expansion portion is located closest to the rear of the vehicle within the trunk, preventing the expansion portion from excessively interfering with the layout of other structures and preventing other structures from affecting the expansion portion's placement. Furthermore, since the gas tank and air pump are located on either side of the expansion portion along the central axis, the space behind the vehicle's rear suspension can be maximized, thereby improving the overall vehicle's space utilization efficiency.

[0012] In some embodiments, the vehicle body structure further includes an adapter bracket. The adapter bracket is located between the air pump and the longitudinal beam, and includes an air pump connection portion and a longitudinal beam connection portion. The air pump connection portion is connected to the air pump, and the longitudinal beam connection portion is connected to the longitudinal beam. The air pump connection portions are located on both sides of the longitudinal beam connection portion.

[0013] By setting up an adapter bracket, vibration can be better blocked, that is, some vibrations of the air pump can be blocked by the adapter bracket, so that the body structure can have a better vibration elimination effect, and further reduce the impact of the vibration generated by the air pump on the body structure.

[0014] The adapter bracket can also extend the length between the fixing points of the air pump, that is, the distance between the fixing points of the air pump and the longitudinal beam is extended to the distance between the connecting parts of the air pump, thereby improving the fixing stability of the air pump.

[0015] In some embodiments, the air pump connection portion and the longitudinal beam connection portion are located on the same plane and on the same straight line. The cross-section of the adapter bracket along a line perpendicular to the line connecting the air pump connection portion and the longitudinal beam connection portion is concave, and a cavity is defined within the flange of the adapter bracket.

[0016] This arrangement allows the adapter bracket to better block vibrations, thereby improving the vehicle body structure's ability to eliminate vibrations and further reducing the impact of air pump vibrations on the vehicle body structure. The adapter bracket also features a cavity within its flange, which improves its ability to resist vibration deformation and further enhances its ability to block vibration transmission.

[0017] In some embodiments, the vehicle body structure further includes an air pump bracket. The air pump bracket includes a first mating portion, a second mating portion, and a third mating portion. The first mating portion is connected to the longitudinal beam. The second mating portion is connected to the adapter bracket. The third mating portion is connected to the air pump. The line connecting the projections of the first mating portion and the second mating portion on the same plane forms a triangle.

[0018] The smaller area of ​​the air pump that can be used to cooperate with other parts can be replaced with a larger area, thereby reducing the difficulty of connecting the air pump and improving the installation stability of the air pump.

[0019] In some embodiments, the vehicle body structure further includes a first vibration isolation structure and a second vibration isolation structure. The first vibration isolation structure is located between the air pump and the air pump bracket. The second vibration isolation structure is located between the first mating portion of the air pump bracket and the longitudinal beam, and between the second mating portion of the air pump bracket and the adapter bracket. The first vibration isolation structure comprises a composite structure of a spring and a rubber bushing, and the second vibration isolation structure comprises a rubber bushing.

[0020] With this arrangement, the vibration generated by the air pump can be better blocked by the arrangement of the first vibration isolation structure and the second vibration isolation structure, thereby allowing the vehicle body structure to have a better vibration elimination effect, thereby further improving the vehicle's driving experience and the stability of other system operations.

[0021] In some embodiments, the vehicle body structure further includes: a mounting bracket. The mounting bracket is installed on both sides of the air pump bracket, and the mounting bracket and the second matching portion are located on the same straight line. The mounting bracket includes a hook portion extending upward to form a hook shape. The adapter bracket also includes a mounting matching portion. The mounting matching portion is located on both sides of the air pump connecting portion, and the air pump connecting portion is located between the mounting matching portion and the longitudinal beam connecting portion. The mounting matching portion is provided with an opening, and the hook portion and the opening of the mounting matching portion correspond to each other during assembly.

[0022] By providing correspondingly matched hook portions and mounting mating portions, after the air pump is connected to the air pump bracket and the mounting bracket to obtain the first intermediate structure, and after the adapter bracket is connected to the longitudinal beam to obtain the second intermediate structure, the hook portion can be hooked into the opening of the mounting mating portion when the two intermediate structures are installed and mated. This can avoid workers having to constantly lift the air pump and air pump bracket during installation, thereby reducing worker fatigue and improving installation efficiency. Furthermore, when automated installation is used, such a configuration can also avoid the need for a dedicated mechanical structure for lifting, thereby simplifying the mechanical structure for performing the installation and reducing costs.

[0023] In some embodiments, the mounting mating portion is lower than the connection between the air pump connection portion and the longitudinal beam. After installation, a clearance distance is maintained between the hook portion and the mounting mating portion. The mounting mating portion includes an inclined connection structure and is connected to the air pump connection portion via the inclined connection structure.

[0024] This arrangement allows for a space for the hook portion to fit, making it easier for the hook portion to fit with the mounting mating portion, thereby simplifying the installation process. Furthermore, the tilted connection structure can be used to decompose the downward force exerted on the air pump connection by the air pump and its associated structures, thereby reducing the bending force perpendicular to the surface of the tilted connection structure. This, in turn, increases the strength of the tilted connection structure, thereby improving mounting stability during installation.

[0025] In some embodiments, the vehicle body structure further includes: a distribution valve, which is disposed on the mounting bracket and configured to guide the airflow generated by the air pump into different pneumatic circuits.

[0026] In some embodiments, the vehicle body structure further comprises: a bottom plate and a cover plate. The bottom plate is disposed above the crossbeam and the longitudinal beam, and is located on the side of the crossbeam contacting the expansion portion away from the expansion portion. The cover plate is detachably disposed above the crossbeam and the longitudinal beam, and is located on the side of the crossbeam contacting the expansion portion facing the expansion portion. The cover plate is flush with the bottom plate.

[0027] By providing a cover plate flush with the bottom plate, the expansion portion can be temporarily closed in this case, leaving a flat placement space, thereby allowing users to flexibly select different trunk placement space modes according to actual conditions.

[0028] In some embodiments, the longitudinal beam includes a first overlapping flange extending from the bottom of the longitudinal beam; the cross beam includes a third overlapping flange extending from the bottom of the cross beam; the expansion base plate includes a second overlapping flange extending from the top of the expansion portion, and the second overlapping flange is configured to overlap with the first overlapping flange and the third overlapping flange to fix the expansion portion.

[0029] In some embodiments, the first overlapping flange and the longitudinal beam, the third overlapping flange and the transverse beam, and the second overlapping flange and the expansion portion are respectively formed integrally.

[0030] In some embodiments, the longitudinal beams and the transverse beams are used to support other structural components of the vehicle body structure.

[0031] According to a second aspect of the present application, a vehicle is provided, comprising any one of the above-mentioned vehicle body structures, wherein the power system of the vehicle does not include a tail pipe muffler structure.

[0032] This arrangement can avoid interference between the expansion part and the tail pipe muffler structure on the vehicle, so that the vehicle trunk can be expanded through the expansion part without affecting the operation of the vehicle.

[0033] It should be understood that the above general description and the following detailed description are only exemplary and explanatory and are not limiting of the present application. Other aspects will become apparent upon reading and understanding the accompanying drawings and detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0045] With the improvement of living standards, people have the need to use cars for various activities, such as camping, and these activities have placed higher demands on the vehicle's storage space. Since the vehicle needs to take into account both the stability during driving and the vehicle's passability, it is necessary to install an air suspension system on the vehicle. Installing an air suspension system requires installing an air tank and an air pump within the vehicle's body structure. Taking into account various factors in the vehicle's body structure design, the air tank and air pump generally need to be installed in the vehicle's trunk. However, when the air tank and air pump are installed in the trunk, they not only occupy the space at the rear of the vehicle, which limits the expansion of the trunk space, but also are not conducive to solving the vibration caused by the operation of the air pump.

[0046] The present invention provides a vehicle body structure 10. FIG1 is a schematic diagram of a partial structure of the vehicle body structure 10, and FIG2 is a bottom view of the partial structure of the vehicle body structure 10. As shown in FIG1 and FIG2, the vehicle body structure 10 includes a longitudinal beam 11, a cross beam 12, a trunk 13, an air tank 14, an air pump 15, and a rear suspension 23.

[0047] The longitudinal beam 11 and the cross beam 12 are connected to each other and are used to support other structural components of the vehicle body structure 10. The longitudinal beam 11 extends into the trunk 13.

[0048] The projections of the longitudinal beams 11 and the cross beams 12 on the horizontal plane can remain perpendicular to each other, and the vehicle body frame is connected by the connection between the longitudinal beams 11 and the cross beams 12. Subsequent structures are directly or indirectly connected to the body frame composed of the longitudinal beams 11 and the cross beams 12 to form a complete vehicle.

[0049] The air pump 15 is connected to the longitudinal beam 11 extending into the trunk 13. The air pump 15 and the air tank 14 are arranged on both sides of the central axis X of the vehicle body structure 10 and are located near the rear suspension 23.

[0050] Since the air pump 15 generates a large amount of vibration during operation, in order to prevent the vibration generated by the air pump 15 from affecting other parts of the vehicle body structure 10 and the driving experience of the vehicle, the requirements for vibration control of the air pump 15 are relatively strict. In addition, since the longitudinal beam 11 is one of the main supporting structures of the vehicle, its beam wall is thicker and its structure is stronger. Therefore, when the vibration of the air pump 15 is transmitted to the longitudinal beam 11, the longitudinal beam 11 can block most of the vibration, thereby having a good effect of reducing vibration. Therefore, the air pump 15 is connected to the longitudinal beam 11, and the longitudinal beam 11 can block part of the vibration generated by the air pump 15, thereby reducing the impact of the vibration generated by the air pump 15 on the vehicle body structure 10, and further, improving the driving experience of the vehicle and the stability of the operation of other systems.

[0051] FIG2 also shows a longitudinal direction Y, which corresponds to the length of the vehicle. Positioning the air pump 15 and the air tank 14 on either side of the central axis X of the vehicle body structure 10 reduces the space occupied by the air pump 15 and the air tank 14 in the longitudinal direction Y. This arrangement allows the air pump 15 and the air tank 14 to accommodate various rear overhang lengths (i.e., the length from the center of the rear wheel to the rear of the vehicle), thereby expanding the range of vehicle models that can accommodate this arrangement.

[0052] After the air pump 15 and the air tank 14 are arranged as described above, usable space exists below the trunk 13, within the area enclosed by the longitudinal beams 11, the transverse beams 12, and the rear panel 131. Therefore, as shown in Figures 1 and 2, in some embodiments, the trunk 13 may further include an expansion floor 133 and a rear panel 131 defining an expansion portion 132.

[0053] In the area enclosed by the longitudinal beams 11 , transverse beams 12 and rear panel 131 , the lower surfaces of the longitudinal beams 11 , transverse beams 12 and rear panel 131 are connected and flush with the expansion base plate 133 . The expansion base plate 133 extends downward to form a concave structure serving as the expansion portion 132 .

[0054] The air pump 15 and the air tank 14 are located on both sides of the expansion portion 132 along the central axis X.

[0055] 1 shows a vertically extending height direction Z. The aforementioned expansion portion 132 is a concave structure extending downward, that is, the expansion portion 132 extends in a direction opposite to the height direction Z.

[0056] 3 is a cross-sectional view taken along line AA of FIG1 , and FIG4 is a cross-sectional view taken along line BB of FIG1 . The expansion portion 132 is a concave structure extending in a direction opposite to the height direction Z. For details, see FIG3 and FIG4 .

[0057] Through the above arrangement, the volume of the trunk 13 can be expanded through the expansion portion 132. Moreover, since the expansion portion 132 is located in the area enclosed by the longitudinal beam 11, the cross beam 12 and the rear panel 131, the expansion portion 132 is located in the position closest to the rear of the vehicle in the trunk 13, thereby reducing the number of structures that may interfere with the expansion portion 132 to a minimum, avoiding excessive interference of the expansion portion 132 with the arrangement of other structures, and also avoiding other structures affecting the arrangement of the expansion portion 132. At the same time, since the gas tank 14 and the air pump 15 are located on both sides of the expansion portion 132 along the central axis X, it is also possible to maximize the use of the space behind the rear suspension 23 of the vehicle, that is, the space on the side of the rear suspension 23 toward the rear of the vehicle along the length direction Y, thereby improving the space utilization efficiency of the entire vehicle.

[0058] As an important substructure within the vehicle body structure 10, the air pump 15 generates significant vibration during operation. FIG5 illustrates a schematic diagram of the assembly of the air pump 15 and related structures. As shown in FIG5 , in some embodiments, the vehicle body structure 10 further includes an adapter bracket 16 .

[0059] Figure 6 is a schematic diagram of the structure of the adapter bracket 16, and Figure 7 is a schematic diagram of the connection between the adapter bracket 16 and the longitudinal beam 11. Referring to Figures 6 and 7, the adapter bracket 16 is located between the air pump 15 and the longitudinal beam 11, and the adapter bracket 16 includes a longitudinal beam connecting portion 161 and an air pump connecting portion 162, for example, two or more longitudinal beam connecting portions 161 and two or more air pump connecting portions 162. The air pump connecting portion 162 is used to connect to the air pump 15, and the longitudinal beam connecting portion 161 is used to connect to the longitudinal beam 11.

[0060] In the direction in which the adapter bracket 16 extends along the longitudinal beam 11 , the air pump connection portion 162 is located on both sides of the longitudinal beam connection portion 161 . In other words, the longitudinal beam connection portion 161 is sandwiched between the air pump connection portions 162 , as shown in FIG6 .

[0061] Although the longitudinal beam 11 already has a good ability to block vibrations, and the fixing points on the longitudinal beam 11 are sufficient to mount the air pump 15 on the longitudinal beam 11, the provision of the adapter bracket 16 can further block vibrations. In other words, the adapter bracket 16 further blocks some of the vibration of the air pump 15, thereby allowing the vehicle body structure 10 to have a better vibration-eliminating effect, and further reducing the impact of the vibration generated by the air pump 15 on the vehicle body structure 10.

[0062] The adapter bracket 16 can also extend the length between the fixing points of the air pump 15, that is, the distance between the fixing points of the air pump 15 and the longitudinal beam 11 is extended to the distance between the air pump connecting parts 162, thereby improving the fixing stability of the air pump 15.

[0063] In some embodiments, as shown in Figure 6 , the air pump connection portion 162 and the longitudinal beam connection portion 161 are located on the same plane of the adapter bracket 16 and on the same straight line approximately parallel to the longitudinal direction of the adapter bracket 16. The cross-section of the adapter bracket 16 perpendicular to the line connecting the air pump connection portion 162 and the longitudinal beam connection portion 161 is concave, and a cavity 164 is defined within the flange of the adapter bracket 16. In some embodiments, the adapter bracket 16 is stamped and formed from a 1.5 mm thick circular tube, for example, but the present application is not limited thereto.

[0064] The flanges of the adapter bracket 16 are the structures on both sides of the "concave" shape.

[0065] By arranging the air pump connection portion 162 and the longitudinal beam connection portion 161 on the same plane and on the same straight line, the adapter bracket 16 can better block vibration, thereby allowing the vehicle body structure 10 to have a better vibration elimination effect, and further reducing the impact of the vibration generated by the air pump 15 on the vehicle body structure 10.

[0066] Furthermore, the concave cross-section of the adapter bracket 16 enhances its strength, allowing it to better support the air pump 15 while more stably isolating vibrations, thereby achieving a vibration-eliminating effect. The flange of the adapter bracket 16 also includes a cavity 164, thereby improving the adapter bracket's ability to resist vibration deformation and, in turn, further enhancing the adapter bracket's ability to block vibration transmission.

[0067] In some embodiments, the vehicle body structure 10 further includes an air pump bracket 17 .

[0068] Figure 8 shows an exploded view of the assembly shown in Figure 5, excluding the adapter bracket 16. As shown in Figure 8, the air pump bracket 17 includes a first mating portion 171, a second mating portion 172, and a third mating portion 173. The first mating portion 171 is connected to the longitudinal beam 11. The second mating portion 172 is connected to the adapter bracket 16. The third mating portion 173 is connected to the air pump 15.

[0069] By connecting the air pump 15 to the air pump bracket 17, the smaller area of ​​the air pump 15 available for cooperation with other parts can be replaced with a larger area, thereby reducing the connection difficulty of the air pump 15 and improving the installation stability of the air pump 15.

[0070] A line connecting the projections of the first matching portion 171 and the second matching portion 172 on the same plane forms a triangle.

[0071] By making the line connecting the projections of the first matching portion 171 and the second matching portion 172 on the same plane a triangle, the installation stability of the air pump bracket 17 can be improved due to the high stability of the triangular structure, thereby further improving the installation stability of the air pump 15.

[0072] In some embodiments, as shown in FIG. 5 and FIG. 8 , the vehicle body structure 10 further includes a first vibration isolation structure 181 and a second vibration isolation structure 182 .

[0073] The first vibration isolation structure 181 is located between the air pump 15 and the air pump bracket 17 . The second vibration isolation structure 182 is located between the first matching portion 171 of the air pump bracket 17 and the longitudinal beam 11 , and between the second matching portion 172 of the air pump bracket 17 and the adapter bracket 16 .

[0074] It should be noted that the first vibration isolation structure 181 herein being located between the air pump 15 and the air pump bracket 17 refers to the first vibration isolation structure 181 being located between the structure of the air pump 15 and the structure of the air pump bracket 17. As shown in Figures 5 and 8 , although the first vibration isolation structure 181 is located on the side of the air pump bracket 17 that is away from the majority of the air pump 15 structure, since the first vibration isolation structure 181 is located on the mounting structure extending from the air pump 15, and the mounting structure ultimately passes through the air pump bracket 17, the first vibration isolation structure 181 abuts against the mounting structure extending from the air pump 15 and the air pump bracket 17. Therefore, at this time, the first vibration isolation structure 181 is still located between the air pump 15 and the air pump bracket 17.

[0075] Similarly, the second vibration isolation structure 182 is located between the first mating portion 171 of the air pump bracket 17 and the longitudinal beam 11, and between the second mating portion 172 of the air pump bracket 17 and the adapter bracket 16. This means that the second vibration isolation structure 182 is located between the structure of the first mating portion 171 of the air pump bracket 17 and the structure of the longitudinal beam 11, and between the structure of the second mating portion 172 of the air pump bracket 17 and the structure of the adapter bracket 16. As shown in Figures 5 and 8, the first mating portion 171 and the second mating portion 172 have the second vibration isolation structure 182. When the first mating portion 171 is connected to the longitudinal beam 11, the second vibration isolation structure 182 abuts against the longitudinal beam 11 to reduce vibration when the first mating portion 171 is connected to the longitudinal beam 11. When the second mating portion 172 is connected to the adapter bracket 16, the second vibration isolation structure 182 abuts against the air pump connection portion 162 of the adapter bracket 16 to reduce vibration when the second mating portion 172 is connected to the adapter bracket 16.

[0076] The first vibration isolation structure 181 includes a composite structure of a spring and a rubber bushing, and the second vibration isolation structure 182 includes a rubber bushing.

[0077] This arrangement allows different vibration isolation structures to isolate vibrations in different locations. Because the vibration between the air pump 15 and the air pump bracket 17 is greater than the vibration between the adapter bracket 16 and the longitudinal beam 11, a composite structure of a spring and a rubber bushing is selected between the air pump 15 and the air pump bracket 17 to isolate vibrations.

[0078] Since the vibration between the adapter bracket 16 and the longitudinal beam 11 is small, a rubber bushing structure with relatively weak vibration isolation capability can be used to isolate the vibration between the adapter bracket 16 and the longitudinal beam 11. At the same time, since the cost of the rubber bushing structure is lower than that of the composite structure of the spring and the rubber bushing, further cost savings can be achieved while meeting the vibration control requirements.

[0079] The arrangement of the first vibration isolation structure 181 and the second vibration isolation structure 182 can better block the vibration generated by the air pump 15, thereby allowing the vehicle body structure 10 to have a better vibration elimination effect, thereby further improving the vehicle's driving experience and the stability of other system operations.

[0080] In some embodiments, as shown in FIG. 5 and FIG. 8 , the vehicle body structure 10 further includes a mounting bracket 19 .

[0081] The mounting bracket 19 is mounted on both sides of the air pump bracket 17, and the mounting bracket 19 and the second matching portion 172 are located on the same straight line. The mounting bracket 19 includes a hook portion 191 extending upward to form a hook shape.

[0082] In some embodiments, the mounting bracket 19 and the second matching portion 172 are located on the same straight line, that is, the main structure of the mounting bracket 19 and the main structure of the second matching portion 172 are located on the same straight line.

[0083] The adapter bracket 16 also includes mounting mating portions 163. Mounting mating portions 163 are located on either side of the air pump connection portion 162, with the air pump connection portion 162 positioned between the mounting mating portions 163 and the longitudinal beam connection portion 161. Mounting mating portions 163 have openings 1631, and the hook portion 191 mates with the openings 1631 of the mounting mating portions 163 during assembly.

[0084] By providing corresponding matching hook portions 191 and mounting matching portions 163, after completing the connection between the air pump 15 and the air pump bracket 17 and the mounting bracket 19 to obtain the first intermediate structure, and completing the connection between the adapter bracket 16 and the longitudinal beam 11 to obtain the second intermediate structure, when the two intermediate structures are installed and matched, the hook portion 191 is hung into the opening 1631 of the mounting matching portion 163, thereby avoiding the workers from constantly holding the air pump 15 and the air pump bracket 17 during installation, thereby reducing worker fatigue and improving installation efficiency. Moreover, when using automated installation, such a setting can also avoid the need for a dedicated mechanical structure for holding, thereby simplifying the mechanical structure for performing the installation and thereby reducing costs.

[0085] In some embodiments, as shown in FIG. 5 and FIG. 8 , the vehicle body structure 10 further includes a distribution valve 20 .

[0086] The distribution valve 20 is disposed on the mounting bracket 19 and is used to direct the air flow generated by the air pump 15 into different pneumatic circuits.

[0087] By arranging the distribution valve 20 on the mounting bracket 19, the distribution valve 20 can be connected to the air pump 15 before connecting the air pump bracket 17 to the adapter bracket 16 and the longitudinal beam 11. Since the installation at this time is not interfered with by other vehicle body structural parts, the connection accuracy between the distribution valve 20 and the air pump 15 can be improved, thereby improving the air tightness and other performance between the distribution valve 20 and the air pump 15, and further, the working stability of the air pump 15 and the pneumatic circuit connected thereto can be improved.

[0088] Moreover, the space occupied by the distribution valve 20, the air pump 15 and the air tank 14 in the length direction Y can be further shortened, so that the air pump 15 and the air tank 14 arranged in this way can be further adapted to more various rear overhang lengths, and further, the vehicle models that the arrangement of the above-mentioned air pump 15 and the air tank 14 can adapt to can be further expanded.

[0089] 5 and 6 , the mounting portion 163 is lower than the air pump connection portion 162 and the longitudinal beam connection portion 161. After installation, a clearance is maintained between the hook portion 191 and the mounting portion 163.

[0090] In some embodiments, as shown in regions Q1 and Q2 in FIG. 5 , a clearance distance is maintained between the hook portion 191 and the mounting mating portion 163. This prevents the hook portion 191 from contacting the mounting mating portion 163 when the air pump 15 vibrates, thereby preventing the effects of various vibration isolation designs. The specific length of the clearance distance can be flexibly set according to actual needs.

[0091] This arrangement can reserve a matching space for the hook portion 191, making it easier for the hook portion 191 to match with the mounting matching portion 163, thereby improving the ease of installation operation.

[0092] The mounting fitting portion 163 includes an inclined connection structure 1632 and is connected to the air pump connection portion 162 via the inclined connection structure 1632 .

[0093] By setting up the inclined connection structure 1632, the downward force exerted by the air pump 15 and the related structures connected to it on the mounting fitting part 163 can be decomposed, thereby reducing the bending force perpendicular to the surface of the inclined connection structure 1632. Furthermore, the strength of the inclined connection structure 1632 can be improved to improve the mounting stability during the installation process.

[0094] In some embodiments, as shown in FIG1 , the vehicle body structure 10 further includes a bottom plate 21 and a cover plate 22 .

[0095] The bottom plate 21 is disposed on the cross beam 12 and the longitudinal beam 11 , and is located on a side of the cross beam 12 that contacts the expansion portion 132 and is away from the expansion portion 132 .

[0096] The cover plate 22 is detachably mounted on the cross beam 12 and the longitudinal beam 11 and is located on the side of the cross beam 12 that contacts the expansion portion 132 and faces the expansion portion 132. The cover plate 22 is flush with the bottom plate 21.

[0097] Since the expansion portion 132 is a downwardly concave structure, it can be difficult to place items that require a larger surface area. However, by providing a cover plate 22 flush with the bottom plate 21, the expansion portion 132 can be temporarily closed in such situations, leaving a flat storage space. This allows the user to flexibly select different storage space modes for the trunk 13 according to actual conditions.

[0098] In some embodiments, as shown in Figures 1, 3, 4 and 7, the longitudinal beam 11 includes a first overlapping flange 111, and the transverse beam 12 includes a third overlapping flange 121. The first overlapping flange 111 starts from the bottom of the longitudinal beam 11 and extends out of the longitudinal beam 11, and the third overlapping flange 121 starts from the bottom of the transverse beam 12 and extends out of the transverse beam 12.

[0099] Specifically, the cross beam 12 and the longitudinal beam 11 can be long strip structures with a rectangular cross section, including opposite upper surfaces and opposite lower surfaces. That is, in the height direction Z, the upper surface is the upper surface of the cross beam 12 and the upper surface of the longitudinal beam 11, and the lower surface is the lower surface of the cross beam 12 and the lower surface of the longitudinal beam 11. The first overlapping flange 111 is a surface structure extending from the lower surface of the longitudinal beam 11 to the longitudinal beam 11, and the third overlapping flange 121 is a surface structure extending from the lower surface of the cross beam 12 to the cross beam 12. For more details, please refer to Figures 4 and 7.

[0100] The expansion base plate 133 includes a second overlapping flange 1321 extending from the top of the expansion portion 132. The second overlapping flange 1321 is located above the first overlapping flange 111 and the third overlapping flange 121 and overlaps with the first overlapping flange 111 and the third overlapping flange 121.

[0101] In some embodiments, the second overlapping flange 1321 is a portion of the expanded bottom plate 133 outside the expanded portion 132 .

[0102] Moreover, at the overlap of the first overlap flange 111 and the third overlap flange 121 and the second overlap flange 1321, a riveting process can be adopted for the first overlap flange 111 and the second overlap flange 1321, or a process of filling sealant between the first overlap flange 111 and the second overlap flange 1321 can be adopted, or the above processes can be adopted simultaneously, but are not limited to this. Similarly, a riveting process can be adopted for the third overlap flange 121 and the second overlap flange 1321, or a process of filling sealant between the third overlap flange 121 and the second overlap flange 1321 can be adopted, or the above processes can be adopted simultaneously, but are not limited to this.

[0103] It should be noted that the first overlapping flange 111, the third overlapping flange 121 and the second overlapping flange 1321 are only for the convenience of description. In fact, the first overlapping flange 111 and the longitudinal beam 11, the third overlapping flange 121 and the transverse beam 12, and the second overlapping flange 1321 and the expansion portion 132 are all formed integrally.

[0104] This arrangement can better achieve the coordination between the expansion portion 132 and the cross beam 12 and the longitudinal beam 11 , thereby improving the stability of the coordination between the expansion portion 132 and the cross beam 12 and the longitudinal beam 11 .

[0105] The present application also provides a vehicle. The vehicle includes any of the above-described body structures 10. Furthermore, the vehicle's power system does not include a tailpipe muffler structure. For example, the vehicle may be a pure electric vehicle, but is not limited thereto. The vehicle may also be other vehicles that do not require a tailpipe muffler structure.

[0106] This arrangement can avoid interference between the expansion portion 132 and the tail pipe muffler structure on the vehicle, thereby allowing the expansion of the vehicle trunk 13 through the expansion portion 132 without affecting the operation of the vehicle.

[0107] The above embodiments of the present application can complement each other if no conflict occurs.
