Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile manufacturing, in particular to a vehicle body structure and a vehicle. BACKGROUND

[0002] In the related art, with the development of technology, vehicles are increasingly present in people's lives. And people's requirements for vehicles are also getting higher and higher. Among them, with the improvement of living standards, people have the demand to carry out various activities through vehicles, such as camping through vehicles, and these activities all put forward higher requirements for the storage space of the vehicle.

[0003] However, in order to make the vehicle balance and passability when driving, it is necessary to set up an air suspension system on the vehicle. The air pump of the air suspension system will produce a large vibration when running, which is not conducive to the vibration control of the whole vehicle, therefore, it is urgent to design the related vibration control. SUMMARY

[0004] According to a first aspect of the embodiments 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;

[0005] The longitudinal beam and the cross beam are connected to each other, and the longitudinal beam and the cross beam are used to support other structural components of the vehicle body structure; the longitudinal beam extends into the trunk;

[0006] 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 center axis of the vehicle body structure and located close to the rear suspension.

[0007] In this way, when the vibration is transmitted to the longitudinal beam, the structure of the longitudinal beam can block a large amount of vibration, so as to have a good effect of reducing vibration. Therefore, the air pump is connected to the longitudinal beam, and the vibration generated by the air pump can be blocked by the longitudinal beam, so as to reduce the influence of the vibration generated by the air pump on the vehicle body structure, and further improve the driving experience of the vehicle and the stability of the operation of other systems.

[0008] And the air pump and the air tank are arranged on both sides of the center axis of the vehicle body structure, that is, 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 more various rear suspension lengths, that is, the length from the center of the rear wheel of the vehicle to the tail of the vehicle, and further, the vehicle models that the setting scheme of the air pump and the air tank can adapt to can be expanded.

[0009] In some embodiments, the trunk further comprises an expansion part and a rear panel.

[0010] The rear panel is connected to one end of the longitudinal beam; in the area surrounded by the longitudinal beam, the transverse beam and the rear panel, the lower surfaces of the longitudinal beam, the transverse beam and the rear panel are connected to the expanded bottom plate and are flush with each other; the recess structure formed by the downward extension of the expanded bottom plate is the expansion part;

[0011] The air pump and the air tank are located on both sides of the expansion part.

[0012] In this way, since the expansion part is located at the position closest to the tail in the trunk, the number of structures interfering with the expansion part is minimized, avoiding excessive interference with the arrangement of other structures, and also avoiding the influence of other structures on the arrangement of the expansion part. At the same time, since the air tank and the air pump are located on both sides of the expansion part, the space behind the rear suspension of the vehicle can be maximally utilized, thereby improving the space utilization efficiency of the whole vehicle.

[0013] In some embodiments, further comprising: an adapter bracket.

[0014] The adapter bracket is located between the air pump and the longitudinal beam, and the adapter bracket comprises an air pump connecting part and a longitudinal beam connecting part. The air pump connecting part is connected to the air pump, and the longitudinal beam connecting part is connected to the longitudinal beam.

[0015] The air pump connecting part is located on both sides of the longitudinal beam connecting part.

[0016] By setting the adapter bracket, the vibration can be better blocked, that is, some vibrations are further blocked by the adapter bracket, so that the vehicle body structure has better vibration elimination effect, and thus the influence of the vibration generated by the air pump on the vehicle body structure can be further reduced.

[0017] The length between the fixing points of the air pump can also be expanded by the adapter bracket, that is, the distance between the fixing points of the air pump and the longitudinal beam is expanded to the distance between the air pump connecting parts, so that the fixing stability of the air pump can be improved.

[0018] In some embodiments, the air pump connecting part and the longitudinal beam connecting part are located on the same plane and on the same straight line. The cross section of the adapter bracket is "concave", and a cavity is arranged in the flange of the adapter bracket.

[0019] In this way, the adapter bracket can better block the vibration, so that the vehicle body structure has better vibration elimination effect, and thus the influence of the vibration generated by the air pump on the vehicle body structure can be further reduced. In addition, the cavity is arranged in the flange of the adapter bracket, so that the vibration deformation resistance of the adapter bracket can be improved, and thus the vibration transmission blocking capability of the adapter bracket can be further enhanced.

[0020] In some embodiments, further comprising: an air pump bracket.

[0021] The air pump bracket comprises a first fitting part, a second fitting part and a third fitting part. The first fitting part is connected with the longitudinal beam. The second fitting part is connected with the adapter bracket. The third fitting part is connected with the air pump.

[0022] The connecting line of the projections of the first fitting part and the second fitting part on the same plane is a triangle.

[0023] The smaller area of the air pump available for cooperation with other parts can be replaced by a larger area, so that the connection difficulty of the air pump can be reduced, and the installation stability of the air pump can be improved.

[0024] In some embodiments, further comprising a first vibration isolation structure and a second vibration isolation structure.

[0025] 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 fitting part and the longitudinal beam, and between the second fitting part and the adapter bracket.

[0026] 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.

[0027] In this way, the vibration generated by the air pump can be better blocked by the first vibration isolation structure and the second vibration isolation structure, so that the vehicle body structure has better vibration elimination effect, and the driving experience of the vehicle and the stability of other system operation are further improved.

[0028] In some embodiments, further comprising a mounting bracket.

[0029] The mounting bracket is mounted on both sides of the air pump bracket, and the mounting bracket and the second fitting part are located on the same straight line. The mounting bracket comprises a hook part extending upward to form a hook shape.

[0030] The adapter bracket further comprises a mounting fitting part. The mounting fitting part is located on both sides of the air pump connecting part, and the air pump connecting part is located between the mounting fitting part and the longitudinal beam connecting part. The mounting fitting part is provided with an opening, and the hook part and the opening of the mounting fitting part correspond and cooperate when assembled.

[0031] By setting the corresponding hook part and the mounting matching part, the hook part can be hung into the opening of the mounting matching part when the two intermediate structures are installed and matched after the connection of the air pump, the air pump support and the mounting support, and the connection of the adapter support and the longitudinal beam is completed, so that the worker can avoid holding the air pump and the air pump support during installation, thereby reducing the worker's fatigue and improving the installation efficiency. Moreover, when automatic installation is adopted, such a setting can also avoid setting a special mechanical structure for lifting, thereby simplifying the mechanical structure for performing installation, and thereby reducing the cost.

[0032] In some embodiments, the height of the mounting matching part is lower than the air pump connecting part and the longitudinal beam connecting part. And after installation is completed, the hook part and the mounting matching part remain an avoidance distance.

[0033] The mounting matching part comprises an inclined connecting structure, and is connected to the air pump connecting part through the inclined connecting structure.

[0034] In this way, a matching space can be reserved for the hook part, so that the hook part can be more easily matched with the mounting matching part, thereby improving the ease of installation operation. And through the setting of the inclined connecting structure, the downward force exerted by the air pump and the related structures connected thereto on the air pump connecting part can be decomposed, thereby reducing the bending force perpendicular to the surface of the inclined connecting structure, and thereby improving the strength of the inclined connecting structure to improve the mounting stability during installation.

[0035] In some embodiments, it further comprises a bottom plate and a cover plate.

[0036] The bottom plate is arranged on the top surface of the cross beam and the longitudinal beam, and is located on the side of the cross beam away from the expansion part and in contact with the expansion part.

[0037] The cover plate is arranged on the top surface of the cross beam and the longitudinal beam in a detachable manner, and is located on the side of the cross beam facing the expansion part. The cover plate is flush with the bottom plate.

[0038] By setting the cover plate flush with the bottom plate, the expansion part can be temporarily closed in this case, and a flat placement space is left, so that the user can flexibly select different spare tire placement space modes according to the actual situation.

[0039] According to a second aspect of the present application, a vehicle is provided, comprising any of the above vehicle body structures. The power system of the vehicle does not comprise a tailpipe muffler structure.

[0040] In this way, interference between the tailpipe muffler structure on the vehicle and the expansion part can be avoided, so that the expansion part can expand the trunk without affecting the operation of the vehicle.

[0041] It should be understood that the general description above and the following detailed description are only exemplary and explanatory, and are not limiting to the present application. BRIEF DESCRIPTION OF DRAWINGS

[0051] The exemplary embodiments will be described in detail herein below with reference to the drawings. In the following description, the same numbers are used to denote the same elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not representative of all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0052] Since the vehicle needs to balance the stability when driving and the passability of the vehicle, it is necessary to provide an air suspension system on the vehicle. The air suspension system needs to be provided in the vehicle body structure of the vehicle. Considering various factors in the design of the vehicle body structure, the air tank and the air pump generally need to be provided at the trunk of the vehicle. However, when the air tank and the air pump are provided at the trunk, they not only occupy the space of the tail of the vehicle, but also limit the expansion of the trunk space, and are not conducive to solving the vibration caused by the operation of the air pump.

[0053] The embodiment of the present application provides a vehicle body structure 10. Figure 1 The partial structure of the vehicle body structure 10 is shown, Figure 2 The partial structure of the vehicle body structure 10 is shown, Figure 1 As shown in the figure, Figure 2 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.

[0054] The longitudinal beam 11 and the cross beam 12 are connected to each other, and the longitudinal beam 11 and the cross beam 12 are used to support other structural components of the vehicle body structure 10. The longitudinal beam 11 extends into the trunk 13.

[0055] The projection of the longitudinal beam 11 and the cross beam 12 on the horizontal plane can be kept perpendicular to each other, and the vehicle body frame is lapped by the connection of the longitudinal beam 11 and the cross beam 12. Subsequent various structures are directly or indirectly connected to the vehicle body frame composed of the longitudinal beam 11 and the cross beam 12 to form a complete vehicle.

[0056] 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 center axis X of the vehicle body structure 10 and located close to the rear suspension 23.

[0057] Since the air pump 15 generates a large amount of vibration when it operates, in order to avoid the vibration generated by the air pump 15 affecting other parts of the vehicle body structure 10 and the driving experience of the vehicle, the requirement for vibration control is more stringent. Since the longitudinal beam 11 is one of the main support structures of the vehicle, the beam wall is thick and the structure is strong, so when the vibration is transmitted to the longitudinal beam 11, the structure can block a large amount of vibration, thereby achieving a good effect of reducing vibration. Therefore, the air pump 15 is connected to the longitudinal beam 11, and the vibration generated by the air pump 15 can be blocked by the longitudinal beam 11, thereby reducing the influence 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 other system operation.

[0058] In addition, Figure 2A length direction Y, i.e. a length direction of the vehicle, is also shown. The air pump 15 and the air tank 14 are arranged on both sides of the center axis X of the vehicle body structure 10, i.e. the space occupied by the air pump 15 and the air tank 14 in the length direction Y is shortened, so that the air pump 15 and the air tank 14 arranged in this way can be adapted to more various rear overhang lengths, i.e. the length from the center of the rear wheel of the vehicle to the tail of the vehicle, and thus the vehicle models that can be adapted by the arrangement of the air pump 15 and the air tank 14 can be expanded.

[0059] After the air pump 15 and the air tank 14 are arranged in the above-mentioned way, there is space that can be utilized below the trunk 13 and in the area enclosed by the longitudinal beam 11, the cross beam 12 and the rear wall 131. Therefore, as shown in Figure 1 With Figure 2 In some embodiments, the trunk 13 further comprises an expansion part 132.

[0060] In the area enclosed by the longitudinal beam 11, the cross beam 12 and the rear wall 131, the lower surfaces of the longitudinal beam 11, the cross beam 12 and the rear wall 131 are connected with and flush with the expansion floor 133. The recess structure formed by the downward extension of the expansion floor 133 is the expansion part 132.

[0061] The air pump 15 and the air tank 14 are located on both sides of the expansion part 132.

[0062] Specifically, Figure 1 The height direction Z extending vertically is shown. The aforementioned expansion part 132 is a recess structure extending downward, i.e. the expansion part 132 extends in the direction opposite to the height direction Z, i.e. the expansion part 132 is a recess structure extending in the direction opposite to the height direction Z.

[0063] And, Figure 3 Shown is Figure 1 A sectional view along the section line AA, Figure 4 Shown is Figure 1 A sectional view along the section line BB. The expansion part 132 is a recess structure extending in the direction opposite to the height direction Z, which can be referred to Figure 3 With Figure 4 The contents shown.

[0064] Through the above arrangement, the volume of the trunk 13 can be enlarged by the expansion part 132. And, since the expansion part is located in the area surrounded by the longitudinal beam 11, the cross beam 12 and the rear wall 131. Therefore, the expansion part 132 is located in the trunk 13 closest to the rear of the vehicle, so as to minimize the number of structures that interfere with the expansion part 132, avoid excessive interference with the arrangement of other structures, and also avoid the influence of other structures on the arrangement of the expansion part 132. At the same time, since the gas tank 14 and the gas pump 15 are located on both sides of the expansion part 132, the space behind the vehicle rear suspension 23, i.e. the space on the side of the rear suspension 23 facing the length direction Y, can be maximized, so as to improve the space utilization efficiency of the whole vehicle.

[0065] The gas pump 15 is an important substructure in the vehicle body structure 10, and needs to be improved because it generates a large amount of vibration when in operation. Figure 5 A combined schematic diagram of the gas pump 15 and related structures is shown. As Figure 5 shown, in some embodiments, the vehicle body structure 10 further comprises a transfer bracket 16.

[0066] Figure 6 A structural schematic diagram of the transfer bracket 16 is shown, Figure 7 A connection schematic diagram of the transfer bracket 16 and the longitudinal beam 11 is shown. Referring to Figure 6 and Figure 7 shown, the transfer bracket 16 is located between the gas pump 15 and the longitudinal beam 11, and the transfer bracket 16 comprises a longitudinal beam connecting part 161 and a gas pump connecting part 162. The gas pump connecting part 162 is connected to the gas pump 15, and the longitudinal beam connecting part 161 is connected to the longitudinal beam 11.

[0067] The gas pump connecting part 162 is located on both sides of the longitudinal beam connecting part 161.

[0068] Although the longitudinal beam 11 has good vibration blocking ability due to its own characteristics, and the fixing points on the longitudinal beam 11 are sufficient to mount the gas pump 15 on the longitudinal beam 11. However, by arranging the transfer bracket 16, the vibration can be better blocked, i.e. some vibration is further blocked by the transfer bracket 16, so that the vehicle body structure 10 has better vibration elimination effect, and the influence of the vibration generated by the gas pump 15 on the vehicle body structure 10 can be further reduced.

[0069] The length between the fixing points of the gas pump 15 can also be enlarged by the transfer bracket 16, i.e. the distance between the fixing points of the gas pump 15 and the longitudinal beam 11 is enlarged to the distance between the gas pump connecting parts 162, so that the fixing stability of the gas pump 15 can be improved.

[0070] In some embodiments, as Figure 6As shown, the air pump connecting part 162 and the longitudinal beam connecting part 161 are located on the same plane and on the same line. The adapter bracket 16 is concave in cross section, and the flange of the adapter bracket 16 is internally provided with a cavity 164.

[0071] The flange of the adapter bracket 16 is the structure on both sides of the concave shape.

[0072] By arranging the air pump connecting part 162 and the longitudinal beam connecting part 161 on the same plane and on the same line, the adapter bracket 16 can better block vibration, so that the vehicle body structure 10 has better vibration elimination effect, and further, the influence of the vibration generated by the air pump 15 on the vehicle body structure 10 can be further reduced.

[0073] In addition, the cross section of the adapter bracket 16 is concave, which can also enhance the strength of the adapter bracket 16, so that it can better support the air pump 15 and more stably block vibration to eliminate vibration. The flange of the adapter bracket 16 is also internally provided with a cavity 164, so that the vibration deformation resistance of the adapter bracket 16 can be improved, and further, the vibration transmission blocking capability of the adapter bracket 16 can be further enhanced.

[0074] In some embodiments, the vehicle body structure 10 further comprises an air pump bracket 17.

[0075] Figure 8 As shown, the air pump bracket 17 comprises a first matching part 171, a second matching part 172 and a third matching part 173. The first matching part 171 is connected with the longitudinal beam 11. The second matching part 172 is connected with the adapter bracket 16. The third matching part 173 is connected with the air pump 15. Figure 5 Figure 8 By connecting the air pump 15 with the air pump bracket 17, the smaller area available for cooperation with other parts of the air pump 15 can be replaced with a larger area, so that the connection difficulty of the air pump 15 can be reduced, and the installation stability of the air pump 15 can be improved.

[0076] The connecting line of the projections of the first matching part 171 and the second matching part 172 on the same plane is a triangle.

[0077] The connecting line of the projections of the first matching part 171 and the second matching part 172 on the same plane is a triangle.

[0078] By making the connecting line of the projections of the first matching part 171 and the second matching part 172 on the same plane a triangle, since the triangle structure has high stability, the installation stability of the air pump bracket 17 can be improved, and further, the installation stability of the air pump 15 can be further improved.

[0079] In some embodiments, as shown in Figure 5 and Figure 8 ​As shown, the vehicle body structure 10 further comprises a first vibration isolation structure 181 and a second vibration isolation structure 182.

[0080] 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 fitting part 171 and the longitudinal beam 11, and between the second fitting part 172 and the adapter bracket 16.

[0081] It is to be noted that the first vibration isolation structure 181 is located between the air pump 15 and the air pump bracket 17, which means that the first vibration isolation structure 181 is located between the structure of the air pump 15 and the structure of the air pump bracket 17. As shown, Figure 5 And as shown, Figure 8 As shown, although the first vibration isolation structure 181 is located on the side of the air pump bracket 17 away from the structure of the air pump 15, since the first vibration isolation structure 181 is located on the mounting structure extending from the air pump 15, and the mounting structure finally passes through the air pump bracket 17, so that the first vibration isolation structure 181 abuts against the mounting structure 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.

[0082] The first vibration isolation structure 181 comprises a composite structure of a spring and a rubber bushing, and the second vibration isolation structure 182 comprises a rubber bushing.

[0083] In this way, different vibration isolation structures can be used to block vibrations at different positions, that is, the amount of vibration accepted by the position between the air pump 15 and the air pump bracket 17 is still relatively large compared to the position between the adapter bracket 16 and the longitudinal beam 11, so a composite structure of a spring and a rubber bushing is selected to block the vibration.

[0084] The amount of vibration accepted by the position between the adapter bracket 16 and the longitudinal beam 11 is smaller, so a rubber bushing structure with relatively weak vibration blocking ability is used to block the vibration, and the cost of the rubber bushing structure is relatively low compared to the cost of the composite structure of the spring and the rubber bushing.

[0085] Since the vibrations generated by the air pump 15 can be better blocked by the first vibration isolation structure 181 and the second vibration isolation structure 182, the vehicle body structure 10 can have better vibration elimination effect, so as to further improve the driving experience of the vehicle and the stability of other systems.

[0086] In some embodiments, as shown, Figure 5 And as shown, Figure 8 The vehicle body structure 10 further comprises a mounting bracket 19.

[0087] The mounting bracket 19 is mounted on both sides of the air pump bracket 17, and the mounting bracket 19 and the second fitting part 172 are located on the same straight line. The mounting bracket 19 comprises a hook part 191 extending upward to form a hook shape.

[0088] Specifically, the mounting bracket 19 and the second matching part 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 part 172 are located on the same straight line.

[0089] The adapter bracket 16 further includes a mounting matching part 163. The mounting matching part 163 is located on both sides of the air pump connecting part 162, and the air pump connecting part 162 is located between the mounting matching part 163 and the longitudinal beam connecting part 161. The mounting matching part 163 is provided with an opening 1631, and the hook part 191 and the opening 1631 of the mounting matching part 163 correspond and match when assembled.

[0090] By setting the corresponding and matching hook part 191 and the mounting matching part 163, when the air pump 15 and the air pump bracket 17 and the mounting bracket 19 are connected and the adapter bracket 16 and the longitudinal beam 11 are connected, the two intermediate structures are installed and matched, the hook part 191 is hung into the opening 1631 of the mounting matching part 163, so that the worker can avoid holding the air pump 15 and the air pump bracket 17 during installation, thereby reducing the worker's fatigue and improving the installation efficiency. And when using automatic installation, such a setting can also avoid setting a special mechanical structure for lifting, thereby simplifying the mechanical structure for performing installation, and thereby reducing the cost.

[0091] In some embodiments, as shown in Figure 5 As shown in Figure 8 The vehicle body structure 10 further includes a distribution valve 20.

[0092] The distribution valve 20 is arranged on the mounting bracket 19 and is used to guide the airflow generated by the air pump 15 into different pneumatic circuits.

[0093] By arranging the distribution valve 20 on the mounting bracket 19, the distribution valve 20 can be connected with the air pump 15 before the air pump bracket 17 and the adapter bracket 16 and the longitudinal beam 11 are connected. Since there is no interference of other vehicle body structure parts at this time, the connection accuracy between the distribution valve 20 and the air pump 15 can be improved, thereby improving the air tightness and other performances between the distribution valve 20 and the air pump 15, and further improving the working stability of the air pump 15 and the pneumatic circuit connected therewith.

[0094] In addition, 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, thereby making the air pump 15 and the air tank 14 arranged in this way further adapt to more various rear overhang lengths, and further expanding the vehicle models that can be adapted by the arrangement scheme of the air pump 15 and the air tank 14.

[0095] In some embodiments, as shown inFigure 5 and Figure 6 As shown, the height of the mounting fitting part 163 is lower than that of the air pump connection part 162 and the longitudinal beam connection part 161. Furthermore, after installation, a clearance distance is maintained between the hook part 191 and the mounting fitting part 163.

[0096] Specifically, such as Figure 5 In the cases shown in regions Q1 and Q2, a clearance distance is maintained between the hook portion 191 and the mounting mating portion 163. This prevents the hook portion 191 from coming into contact with the mounting mating portion 163 when the air pump 15 vibrates, thus avoiding interference with the vibration isolation design. The specific length of the clearance distance can be flexibly set according to actual needs.

[0097] This design allows for sufficient space to fit the hook part 191, making it easier for the hook part 191 to fit with the mounting part 163, thereby improving the ease of installation.

[0098] The mounting and fitting part 163 includes an inclined connecting structure 1632, and is connected to the air pump connecting part 162 through the inclined connecting structure 1632.

[0099] By setting the inclined connection structure 1632, the downward force exerted on the mounting mating part 163 by the air pump 15 and related structures connected thereto can be decomposed, thereby reducing the bending force perpendicular to its surface on the inclined connection structure 1632, and thus improving the strength of the inclined connection structure 1632, thereby improving the mounting stability during the installation process.

[0100] In some embodiments, such as Figure 1 As shown, the vehicle body structure 10 also includes: a floor plate 21 and a cover plate 22.

[0101] The base plate 21 is disposed on the crossbeam 12 and the longitudinal beam 11, and is located on the side of the crossbeam 12 that is in contact with the expansion section 132 away from the expansion section 132.

[0102] The cover plate 22 is detachably mounted on the crossbeam 12 and the longitudinal beam 11, and is located on the side of the crossbeam 12 that contacts the expansion section 132 and faces the expansion section 132. The cover plate 22 is flush with the bottom plate 21.

[0103] Because the expansion section 132 has a downward-recessed structure, it can be unfavorable for placing items that require a large surface area. However, by providing a cover plate 22 flush with the base plate 21, the expansion section 132 can be temporarily closed in this situation, leaving a flat placement space. This allows users to flexibly choose different placement space modes for the trunk 13 according to their actual needs.

[0104] In some embodiments, as shown in Figure 1 、 Figure 3 、 Figure 4 and Figure 7 , the cross beam 12 and the longitudinal beam 11 comprise a first lap flange 111, the first lap flange 111 extends out of the cross beam 12 or the longitudinal beam 11 from the bottom of the cross beam 12 or the longitudinal beam 11.

[0105] Specifically, the cross beam 12 and the longitudinal beam 11 can be a long strip structure with a rectangular cross section, which comprises opposite upper and lower surfaces, i.e. in the height direction Z, the upper surface is the upper surface of the cross beam 12 and the longitudinal beam 11, and the lower surface is the lower surface of the cross beam 12 and the longitudinal beam 11. The first lap flange 111 is a surface structure extending out of the cross beam 12 and the longitudinal beam 11 from the lower surface of the cross beam 12 and the longitudinal beam 11. More specifically, please refer to the schematic diagram of Figure 7 .

[0106] The expansion bottom plate 133 comprises a second lap flange 1321, the second lap flange 1321 extends out of the expansion portion 132 from the top end of the expansion portion 132. The second lap flange 1321 is located above the first lap flange 111 and is in lap joint with the first lap flange 111.

[0107] Specifically, the second lap flange 1321 is the part of the expansion bottom plate 133 other than the expansion portion 132.

[0108] Moreover, the lap joint between the first lap flange 111 and the second lap flange 1321 can be riveted, or can be filled with sealant, or both, but not limited thereto.

[0109] It should be noted that the first lap flange 111 and the second lap flange 1321 are only for ease of description. In fact, the first lap flange 111 and the longitudinal beam 11, the first lap flange 111 and the cross beam 12, and the second lap flange 1321 and the expansion portion 132 are all integrally formed.

[0110] In this way, the expansion portion 132, the cross beam 12 and the longitudinal beam 11 can be better matched, thereby improving the stability of the matching between the expansion portion 132, the cross beam 12 and the longitudinal beam 11.

[0111] The application also provides a vehicle. The vehicle comprises any one of the vehicle body structures 10 described above. Moreover, the power system of the vehicle does not comprise a tailpipe muffler structure. For example, the vehicle can be a pure electric vehicle, but is not limited thereto. The vehicle can also be other vehicles that do not need to be provided with a tailpipe muffler structure.

[0112] In this way, the expansion part 132 can be arranged without interfering with the tailpipe muffler structure on the vehicle, so that the expansion part 132 can expand the trunk 13 without affecting the operation of the vehicle.

[0113] The above embodiments of the present application can be complementary to each other without conflict.

[0114] It is noted that in the drawings, the dimensions of layers and regions can be exaggerated for clarity. Also, it is to be understood that when a layer or element is referred to as being "on" another layer or element, it can be directly on the other element or intervening layers can also be present.
