Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a vehicle body structure assembly and a vehicle. Background Technology

[0002] In related technologies, some vehicles are equipped with air spring systems to achieve functions such as vibration reduction and buffering. The air spring tank is a key component of the air spring system. When arranging it, it often requires a separate space, which reduces the utilization rate of the vehicle's space and increases the overall weight of the vehicle. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides a vehicle body structure assembly and a vehicle.

[0004] According to a first aspect of this disclosure, the vehicle body structure assembly includes a vehicle body structure and an air spring tank. The vehicle body structure includes a body crossbeam and two body longitudinal beams. The two body longitudinal beams extend in the front-to-back direction and are spaced apart in the left-to-right direction. The body crossbeam extends in the left-to-right direction and connects the two body longitudinal beams. The air spring canister is at least partially opposite to the vehicle body crossbeam; Wherein, the air spring canister extends in the left-right direction and is connected to the vehicle body crossbeam; and / or, the air spring canister extends in the left-right direction and is connected to two vehicle body longitudinal beams.

[0005] The air spring canister extends laterally and is at least partially opposite to the vehicle body crossbeam. Essentially, the air spring canister is integrated into the crossbeam and functions as a part of it, thus meeting the structural strength and torsional stiffness requirements of the crossbeam. For the crossbeam itself, while meeting these requirements, a simplified design is possible, effectively reducing its weight and consequently the overall vehicle weight, facilitating lightweight design. Furthermore, by placing the air spring canister at the crossbeam, the available space is effectively utilized, improving space efficiency.

[0006] In some possible embodiments, the vehicle body beam is formed with a groove extending in the left-right direction, and the air spring canister is at least partially disposed within the groove and serves as part of the vehicle body floor.

[0007] By placing the air spring canister at least partially within the groove, the internal space formed by the vehicle body crossbeam itself can be effectively utilized without needing to create a separate space for the air spring canister, thus reusing existing space and improving space utilization. Furthermore, by placing the air spring canister within the groove of the vehicle body crossbeam, the air spring canister and the vehicle body crossbeam can be considered as a unified "crossbeam structure." For the air spring canister, the vehicle body crossbeam provides the space for its installation, and for the vehicle body crossbeam, the air spring canister itself can be considered as part of the "crossbeam structure," thus reinforcing the structure of the vehicle body crossbeam and improving its strength and rigidity.

[0008] In some possible embodiments, the vehicle body beam includes a beam bottom plate and a beam rear side plate; The bottom plate of the crossbeam extends in the left-right direction and in the front-back direction, the rear side plate of the crossbeam extends in the left-right direction and is arranged to extend at least partially in the up-down direction, and the upper or lower side of the rear side plate of the crossbeam is connected to the front or rear side of the bottom plate of the crossbeam to define the groove.

[0009] The bottom plate of the crossbeam, extending in the front-to-back direction, is connected at an angle to the rear side plate of the crossbeam, extending in the vertical direction, thus defining the aforementioned groove. This design is simple and easy to form. For example, the body crossbeam can be integrally cast, but this disclosure does not limit the specific forming method of the body crossbeam. Furthermore, this disclosure does not limit the specific connection position between the rear side plate and the bottom plate of the crossbeam.

[0010] In some possible embodiments, the rear side plate of the crossbeam includes a rear side plate body and a rear side plate flange; The rear side plate body extends vertically, the upper side of the rear side plate body is connected to the front or rear side of the crossbeam bottom plate, and the rear side plate flange is connected to the lower side of the rear side plate body.

[0011] In this design, the upper side of the rear side panel body is connected to the front or rear side of the crossbeam bottom plate, thus defining a downward-facing groove. This means the air spring canister is positioned below the body crossbeam, effectively utilizing the space in the groove below the crossbeam. Furthermore, the rear side panel flange is connected to the lower side of the rear side panel body, facilitating connection with other structural components of the vehicle body.

[0012] In some possible embodiments, the vehicle body structure also includes a middle vehicle floor and a rear vehicle floor located between the two vehicle longitudinal beams; The front side of the crossbeam bottom plate is connected to the middle vehicle floor, the upper side of the crossbeam rear side plate is connected to the rear side of the crossbeam bottom plate, and the lower side of the crossbeam rear side plate is connected to the rear vehicle floor.

[0013] The upper side of the rear side panel of the crossbeam is connected to the rear side of the bottom plate of the crossbeam, and the lower side of the rear side panel of the crossbeam is connected to the rear vehicle floor. Specifically, the rear side panel flange connected to the lower side of the rear side panel body can be connected to the rear vehicle floor. Since the rear side panel body extends in the vertical direction, it can realize the connection between the middle vehicle floor and the rear vehicle floor where there is a vertical height difference, thus improving the convenience of connection.

[0014] In some possible embodiments, the vehicle body structure assembly further includes two mounting structures; The two mounting structures are respectively connected to the two ends of the vehicle body crossbeam in the left-right direction; and / or, the two mounting structures are respectively connected to the two vehicle body longitudinal beams; The air spring canister is connected to two mounting structures at its left and right ends, respectively.

[0015] The installation structure facilitates the installation and arrangement of the left and right ends of the air spring canister, improving the convenience of installation and connection. This installation structure can be constructed in any suitable manner, and this disclosure does not limit its application. Furthermore, during installation, the installation structure can be connected to the vehicle body crossbeam, the vehicle body longitudinal beam, or both; this disclosure does not limit its application either. When both are connected, the connection strength between the vehicle body crossbeam and the vehicle body longitudinal beam can be effectively improved.

[0016] In some possible embodiments, the mounting structure includes a connecting bracket and a mounting bracket; The connecting bracket connects the left and right ends of the vehicle body crossbeam and the vehicle body longitudinal beam on the same side; The mounting bracket is connected to the connecting bracket and to the air spring cylinder.

[0017] The connecting bracket is used to connect the end of the body crossbeam to the body longitudinal beam on the same side, thereby improving the connection strength between the body crossbeam and the body longitudinal beam. The connecting bracket can be constructed in any suitable shape and structure, and this disclosure does not limit it. Furthermore, the connecting bracket can be connected to the body crossbeam and body longitudinal beam using any suitable connection method, and this disclosure also does not limit it.

[0018] In some possible embodiments, the vehicle body beam is formed with a groove extending in the left-right direction; The connecting bracket covers the left and right ends of the groove to define a mounting cavity, and the mounting bracket is disposed within the mounting cavity; The air spring canister is disposed within the groove and located between the two mounting structures.

[0019] The connecting bracket covers the end of the groove and defines a mounting cavity. This defined mounting cavity is equivalent to forming a "box beam" structure at the end of the vehicle body crossbeam, which can more effectively improve the strength of the end of the vehicle body crossbeam and reduce the occurrence of deformation. In addition, the air spring canister is set in the groove and located between the two mounting brackets. The mounting brackets on the left and right sides can limit the air spring canister, effectively restricting its movement in the lateral direction and improving the stability of the installation.

[0020] In some possible embodiments, the mounting bracket includes a bracket body and at least one first threaded sleeve; The bracket body is connected to the connecting bracket, the first threaded sleeve is connected to the bracket body, and the connecting bracket has at least one first mounting hole opposite to the first threaded sleeve. The air spring canister is connected to the first threaded sleeve through at least one first fastener passing through the first mounting hole.

[0021] The bracket body is connected to the connecting bracket, with a first threaded sleeve providing the mounting base. For example, the edge of the bracket body may have a flange, which is welded to the connecting bracket to improve the stability of the connection. The air spring canister is connected to the first threaded sleeve through at least one first fastener passing through a first mounting hole, thereby achieving the installation and fixation of the air spring canister. However, this disclosure does not limit the method of installation and fixation of the air spring canister. In addition, the bracket body and the connecting bracket described above can also be constructed as an integrally formed structure, which is not limited in this respect.

[0022] In some possible embodiments, the air spring canister includes a canister body and two cover plates; The gas tank body extends in the left and right direction and is internally connected in the left and right direction. The two cover plates are respectively sealed and connected to the two open ends of the gas tank body. The two cover plates are respectively connected to the two ends of the vehicle body crossbeam in the left and right directions; and / or, the two cover plates are respectively connected to the two vehicle body longitudinal beams.

[0023] The cover plate is sealed to the open end of the gas cylinder body, thus sealing the gas inside the gas cylinder. During use, gas can be supplied to the air spring through holes made in the cover plate or the wall of the gas cylinder body. In addition, the cover plate can be used to install on the left and right sides of the air spring gas cylinder. For example, the cover plate can be connected to the aforementioned installation structure, but this disclosure does not limit this.

[0024] In some possible embodiments, the cover plate includes a cover plate body and a connecting plate connected to each other; The cover plate body is sealed to the open end of the gas tank body, and at least one second mounting hole is formed on the connecting plate; Wherein, the second mounting hole is for the first fastener to pass through to connect with the vehicle body crossbeam; and / or, the second mounting hole is for the first fastener to pass through to connect with the vehicle body longitudinal beam.

[0025] The cover plate body serves as a seal to improve sealing performance. The second mounting hole on the connecting plate can be positioned opposite to the first mounting hole and the first threaded sleeve. For example, after the bolt passes through the second mounting hole and the first mounting hole in sequence, a threaded connection with the first threaded sleeve is achieved, which is convenient and has high connection strength. However, this disclosure does not limit the specific structure of the cover plate or the specific connection method with the mounting structure.

[0026] In some possible embodiments, the interior of the gas tank body is provided with at least one first reinforcing plate extending in the left-right direction, the first reinforcing plate being capable of dividing the interior space of the gas tank body.

[0027] The first reinforcing plate effectively supports the interior of the gas tank body, minimizing deformation and enhancing its structural strength. The method of arranging the first reinforcing plate within the gas tank body is not limited in this disclosure. Furthermore, the first reinforcing plate can divide the internal space of the gas tank body, allowing for zoned use of the interior. Additionally, the gas tank body and the first reinforcing plate can be integrally extruded from aluminum; however, this disclosure does not limit the specific material or molding process.

[0028] In some possible embodiments, the gas tank body includes an upper cover plate, a front cover plate, a lower cover plate, and a rear cover plate connected in sequence; The first reinforcing plate extends vertically and connects between the upper cover plate and the lower cover plate; and / or, the first reinforcing plate extends longitudinally and connects between the front cover plate and the rear cover plate.

[0029] The above arrangement can enhance the strength of the gas tank body in both vertical and horizontal directions, minimizing deformation in these directions.

[0030] In some possible embodiments, the air spring canister further includes at least one mounting base connected to at least one side of the canister body in the front-rear direction; The vehicle body structure assembly also includes a vehicle floor, the vehicle floor having at least one first floor hole, and the mounting base being connected to the lower surface of the vehicle floor and disposed opposite to the at least one first floor hole.

[0031] The mounting base facilitates the installation and connection of structural components on the vehicle floor, thereby improving installation stability.

[0032] In some possible embodiments, the mounting base includes a mounting box, at least one second reinforcing plate, and at least one second threaded sleeve; The mounting box is connected to the vehicle floor and the gas tank body, the second reinforcing plate is disposed inside the mounting box, and the second threaded sleeve is connected to the mounting box and disposed opposite to the first floor hole.

[0033] The mounting box provides a mounting base; for example, the rear side of the mounting box can be welded to the front side of the gas tank body, and the upper side of the mounting box can be welded to the lower surface of the vehicle floor, improving the installation strength. A second reinforcing plate is set inside the mounting box to improve the overall structural strength of the mounting box. For example, bolts are sequentially passed through seat mounting holes on the seat inside the vehicle and first floor holes to achieve threaded connection with the second threaded sleeve, which is convenient and has high connection strength, but this disclosure does not limit the specific connection method.

[0034] In some possible embodiments, the mounting base is used to provide seat mounting.

[0035] The mounting base provides support for the seat, ensuring the stability and strength of the seat installation.

[0036] In some possible embodiments, the air spring canister further includes at least one overlapping plate connected to at least one side of the canister body in the front-rear direction; The vehicle body structure assembly also includes a vehicle floor, the vehicle floor having at least one second floor hole, and the overlapping plate having at least one overlapping hole, the second floor hole corresponding to and opposite to the overlapping hole.

[0037] The addition of an overlap plate facilitates connection to the vehicle floor, enhancing ease of connection. The overlap plate can be integrally formed on the rear side of the gas tank body and connects to the aforementioned rear vehicle floor. For example, the overlap plate can overlap the aforementioned rear side panel flange, which in turn overlaps the rear vehicle floor. The overlap holes on the overlap plate are aligned with the flange openings on the rear side panel flange and the second floor hole on the rear vehicle floor, facilitating the insertion and connection of fasteners.

[0038] According to a second aspect of this disclosure, a vehicle is also provided, the vehicle including the aforementioned body structure assembly.

[0039] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: the air spring canister extends in the left-right direction and is at least partially opposite to the vehicle body crossbeam. This is equivalent to the air spring canister being integrated into the vehicle body crossbeam and acting as a partial "crossbeam," thereby meeting the structural strength and torsional stiffness requirements of the vehicle body crossbeam. Furthermore, while meeting the structural strength and torsional stiffness requirements, the design of the vehicle body crossbeam can be simplified, effectively reducing its weight and thus the overall weight of the vehicle, facilitating lightweight vehicle design. Additionally, by placing the air spring canister at the vehicle body crossbeam, the space available at that location can be effectively utilized, improving space utilization.

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0055] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours of a specific structure; directional terms such as "upper," "lower," "left," "right," "front," and "rear" refer to the "upper," "lower," "left," "right," "front," and "rear" as defined in the normal operating state of the vehicle, as detailed in the relevant references. Figure 1 and Figure 2As shown; the terms used, such as "first" and "second", are only used to distinguish one element from another and do not indicate any order or importance.

[0056] Reference Figures 1 to 11 As shown, this disclosure provides a vehicle body structure assembly, which includes a vehicle body structure 1 and an air spring canister 2; the vehicle body structure 1 includes a vehicle body crossbeam 11 and two vehicle body longitudinal beams 12, the two vehicle body longitudinal beams 12 extend in the front-rear direction and are spaced apart in the left-right direction, and the vehicle body crossbeam extends in the left-right direction and connects the two vehicle body longitudinal beams 12; the air spring canister 2 is at least partially opposite to the vehicle body crossbeam 11; wherein, the air spring canister 2 extends in the left-right direction and is connected to the vehicle body crossbeam 11; and / or, the air spring canister 2 extends in the left-right direction and is connected to the two vehicle body longitudinal beams 12.

[0057] In the above technical solution, the air spring canister 2 extends in the left-right direction and is at least partially opposite to the vehicle body crossbeam 11. This means the air spring canister 2 is integrated into the vehicle body crossbeam 11 and can function as part of the "crossbeam," thus meeting the structural strength and torsional stiffness requirements of the crossbeam 11. Furthermore, while meeting the structural strength and torsional stiffness requirements, the crossbeam 11 can be simplified in design, effectively reducing its weight and consequently the overall weight of the vehicle, facilitating lightweight vehicle design. Additionally, by placing the air spring canister 2 at the crossbeam 11, the space available at that location can be effectively utilized, improving space utilization.

[0058] Regarding the connection of the air spring tank 2, it can be connected to the vehicle body crossbeam 11, or to the two vehicle body longitudinal beams 12, or it can be connected to both the vehicle body crossbeam 11 and the vehicle body longitudinal beams 12 at the same time. This disclosure does not limit this.

[0059] Optionally, refer to Figure 1 and Figure 3 As shown, the vehicle body beam 11 has a groove 110 extending in the left-right direction, and the air spring canister 2 is at least partially disposed in the groove 110 and serves as part of the vehicle body floor 3.

[0060] In this embodiment, by at least partially placing the air spring canister 2 within the groove 110, the internal space formed by the vehicle body beam 11 itself can be effectively utilized without creating a separate space for the air spring canister 2, thus reusing the existing space and improving space utilization. In addition, by placing the air spring canister 2 within the groove 110 of the vehicle body beam 11, the air spring canister 2 and the vehicle body beam 11 can be regarded as an integral "beam structure". For the air spring canister 2, the vehicle body beam 11 provides space for its installation and arrangement. For the vehicle body beam 11, the air spring canister 2 itself can be regarded as part of the "beam structure", which also strengthens the structure of the vehicle body beam 11, improving its strength and rigidity. Furthermore, the air spring canister 2 can also serve as part of the vehicle body floor 3, providing floor support.

[0061] In one implementation, reference Figure 3 and Figure 4 As shown, the vehicle body crossbeam 11 includes a crossbeam base plate 111 and a crossbeam rear side plate 112; the crossbeam base plate 111 extends in the left-right direction and in the front-back direction, and the crossbeam rear side plate 112 extends in the left-right direction and at least partially extends in the up-down direction. The upper or lower side of the crossbeam rear side plate 112 is connected to the front or rear side of the crossbeam base plate 111 to define a groove 110.

[0062] In this embodiment, the crossbeam base plate 111 extending in the front-rear direction and the crossbeam rear side plate 112 extending in the vertical direction are connected at an angle to define the aforementioned groove 110, resulting in a simple structure that is easy to form. For example, the vehicle body crossbeam 11 can be integrally cast, but this disclosure does not limit the specific forming method of the vehicle body crossbeam 11. In addition, this disclosure does not limit the specific connection position between the crossbeam rear side plate 112 and the crossbeam base plate 111.

[0063] For example, when the groove 1110 is arranged downwards, the upper side of the rear side plate 112 of the crossbeam is connected to the front or rear side of the bottom plate 111 of the crossbeam, that is, the air spring canister 2 is arranged below the body crossbeam 11. Alternatively, when the groove 1110 is arranged upwards, the lower side of the rear side plate 112 of the crossbeam is connected to the front or rear side of the bottom plate 111 of the crossbeam, that is, the air spring canister 2 is arranged above the body crossbeam 11; this disclosure does not limit this.

[0064] In another embodiment, refer to Figure 4 As shown, the rear side plate 112 of the crossbeam includes a rear side plate body 1121 and a rear side plate flange 1122; the rear side plate body 1121 extends in the vertical direction, the upper side of the rear side plate body 1121 is connected to the front or rear side of the bottom plate 111 of the crossbeam, and the rear side plate flange 1122 is connected to the lower side of the rear side plate body 1121.

[0065] In this embodiment, firstly, the upper side of the rear side panel body 1121 is connected to the front or rear side of the crossbeam bottom plate 111, thus defining the groove 110 facing downwards. That is, the air spring canister 2 is arranged below the body crossbeam 11, effectively utilizing the space of the groove 1110 below the body crossbeam 11. Secondly, the rear side panel flange 1122 is connected to the lower side of the rear side panel body 1121. By providing the rear side panel flange 1122, it is convenient to connect with other structural components of the body structure 1. For example, multiple flange openings 1123 are formed on the rear side panel flange 1122, and multiple corresponding second floor openings can be formed on the rear body floor 32 of the body floor 3. Fasteners pass through the flange openings 1123 and the second floor openings to realize the connection between the rear side panel flange 1122 and the rear body floor 32. However, this disclosure does not limit the specific connection method; for example, welding can also be used for connection. Furthermore, the rear side panel body 1121, the rear side panel flange 112, and the crossbeam bottom plate 111 can be constructed as an integral molding structure, which is convenient for processing and molding.

[0066] In one possible embodiment, refer to Figure 3 As shown, the vehicle body structure also includes a middle vehicle floor 31 and a rear vehicle floor 32 located on the two longitudinal beams 12; wherein, the front side of the crossbeam bottom plate 111 is connected to the middle vehicle floor 31, the upper side of the crossbeam rear side plate 112 is connected to the rear side of the crossbeam bottom plate 111, and the lower side of the crossbeam rear side plate 112 is connected to the rear vehicle floor 32.

[0067] In this embodiment, the upper side of the rear side plate 112 of the crossbeam is connected to the rear side of the bottom plate 111 of the crossbeam, and the lower side of the rear side plate 112 is connected to the rear vehicle floor 32. Specifically, the rear side plate flange 1122 connected to the lower side of the rear side plate body 1121 can be connected to the rear vehicle floor 32. Since the rear side plate body 1121 extends in the vertical direction, the connection between the middle vehicle floor 31 and the rear vehicle floor 32, which have a vertical height difference, can be realized, thus improving the convenience of connection.

[0068] In other embodiments, refer to Figures 3 to 7 As shown, the vehicle body structure assembly also includes two mounting structures 4; the two mounting structures 4 are respectively connected to the two ends of the vehicle body crossbeam 11 in the left and right directions; and / or, the two mounting structures 4 are respectively connected to the two vehicle body longitudinal beams 12; wherein, the air spring tank 2 is respectively connected to the two mounting structures 4 at both ends in the left and right directions.

[0069] In this embodiment, the installation structure 4 facilitates the installation and arrangement of the left and right ends of the air spring canister 2, improving the convenience of installation and connection. The installation structure 4 can be constructed in any suitable way, and this disclosure does not limit its application. Furthermore, during installation, the installation structure 4 can be connected to the vehicle body crossbeam 11, the vehicle body longitudinal beam 12, or both; this disclosure does not limit its application either. In the case of connecting both, the connection strength between the vehicle body crossbeam 11 and the vehicle body longitudinal beam 12 can be effectively improved.

[0070] Optionally, refer to Figures 5 to 7 As shown, the mounting structure 4 includes a connecting bracket 41 and a mounting bracket 42; the connecting bracket 41 connects the ends of the vehicle body crossbeam 11 in the left and right directions and the vehicle body longitudinal beam 12 on the same side; the mounting bracket 42 is connected to the connecting bracket 41 and connected to the air spring canister 2.

[0071] In this embodiment, the connecting bracket 41 is used to connect the end of the body crossbeam 11 to the body longitudinal beam 12 on the same side, thereby improving the connection strength between the body crossbeam 11 and the body longitudinal beam 12. The connecting bracket 41 can be constructed in any suitable shape and structure, and this disclosure does not limit it. Furthermore, the connecting bracket 41 can be connected to the body crossbeam 11 and the body longitudinal beam 12 using any suitable connection method, and this disclosure also does not limit it. For example, the edge of the connecting bracket 41 has multiple edge flanges, which are welded to the body crossbeam 11 and the body longitudinal beam 12 to improve the connection strength.

[0072] Optionally, refer to Figures 3 to 7 As shown, the body beam 11 has a groove 110 extending in the left and right direction; the connecting bracket 41 covers the ends of the groove 110 in the left and right direction to define the mounting cavity, and the mounting bracket 42 is disposed in the mounting cavity; the air spring canister 2 is disposed in the groove 110 and located between the two mounting structures 4.

[0073] In this embodiment, the connecting bracket 41 covers the end of the groove 110 and defines a mounting cavity. This defined mounting cavity is equivalent to forming a "box beam"-like structure at the end of the vehicle body crossbeam 11, thereby more effectively improving the strength of the end of the vehicle body crossbeam 11 and reducing the occurrence of deformation. In addition, the air spring canister 2 is disposed in the groove 110 and located between the two mounting brackets 42. The mounting brackets 42 on the left and right sides can limit the air spring canister 2, effectively restricting the movement of the air spring canister 2 in the left and right directions and improving the stability of the installation.

[0074] In one embodiment, reference is made to... Figures 5 to 7As shown, the mounting bracket 42 includes a bracket body 421 and at least one first threaded sleeve 422; the bracket body 421 is connected to the connecting bracket 41, the first threaded sleeve 422 is connected to the bracket body 421, the connecting bracket 41 has at least one first mounting hole 411 opposite to the first threaded sleeve 422, and the air spring canister 2 is connected to the first threaded sleeve 422 through at least one first fastener passing through the first mounting hole 411.

[0075] In this embodiment, the bracket body 421 is connected to the connecting bracket 41, with the first threaded sleeve 422 providing the mounting base. For example, the edge of the bracket body 421 may have a flange, which is connected to the connecting bracket 41 by welding, thereby improving the stability of the connection. The air spring canister 2 is connected to the first threaded sleeve 422 through at least one first fastener passing through the first mounting hole 411, thereby achieving the installation and fixation of the air spring canister 2. However, this disclosure does not limit the method of installation and fixation of the air spring canister 2. In addition, the bracket body 421 and the connecting bracket 41 described above may also be constructed as an integrally formed structure, which is not limited in this respect.

[0076] In another embodiment, reference is made to... Figures 8 to 11 As shown, the air spring canister 2 includes a canister body 21 and two cover plates 22; the canister body 21 extends in the left and right direction and is internally connected in the left and right direction, and the two cover plates 22 are respectively sealed to the two open ends of the canister body 21; wherein, the two cover plates 22 are respectively connected to the two ends of the vehicle body crossbeam 11 in the left and right direction; and / or, the two cover plates 22 are respectively connected to the two vehicle body longitudinal beams 12.

[0077] In this embodiment, the cover plate 22 is sealed to the open end of the gas tank body 21, thereby sealing the gas inside the gas tank body 21. During use, gas can be supplied to the air spring through openings in the cover plate 22 or the wall of the gas tank body 21. Additionally, the cover plate 22 can be used to mount the air spring gas tank 2 on both sides. For example, the cover plate 22 can be connected to the aforementioned mounting structure 4, but this disclosure does not limit this connection.

[0078] In one embodiment, reference is made to...

[0079] The cover plate body 221 serves as a seal to improve sealing performance. The second mounting hole 2220 on the connecting plate 222 can be positioned opposite to the first mounting hole 411 and the first threaded sleeve 422. For example, after the bolt passes through the second mounting hole 2220 and the first mounting hole 411 in sequence, a threaded connection with the first threaded sleeve 422 is achieved, which is convenient and has high connection strength. However, this disclosure does not limit the specific structure of the cover plate 22 or the specific connection method with the mounting structure 4.

[0080] In another embodiment, reference is made to... Figure 9 As shown, at least one first reinforcing plate 23 extending in the left-right direction is provided inside the gas tank body 21, and the first reinforcing plate 23 can divide the internal space of the gas tank body 21.

[0081] The first reinforcing plate 23 can effectively support the interior of the gas tank body 21, minimizing deformation and improving its structural strength. This disclosure does not limit the arrangement of the first reinforcing plate 23 within the gas tank body 21. Furthermore, the first reinforcing plate 23 can divide the internal space of the gas tank body 21, allowing for zoned use of the interior. Additionally, the gas tank body 21 and the first reinforcing plate 23 can be integrally extruded from aluminum; however, this disclosure does not limit the specific material or molding process.

[0082] In other implementations, refer to Figure 9 As shown, the gas tank body 21 includes an upper cover plate 211, a front cover plate 212, a lower cover plate 213, and a rear cover plate 214 connected in sequence; a first reinforcing plate 23 extends in the vertical direction and is connected between the upper cover plate 211 and the lower cover plate 213; and / or, the first reinforcing plate 23 extends in the front-rear direction and is connected between the front cover plate 212 and the rear cover plate 214.

[0083] In this embodiment, the strength of the gas tank body 21 can be increased in the vertical and horizontal directions and in the front and back directions by the above arrangement, so as to avoid deformation of the gas tank body 21 in the vertical and horizontal directions and in the front and back directions as much as possible.

[0084] Optionally, refer to Figure 11 As shown, the air spring canister 2 also includes at least one mounting base 24, which is connected to at least one side of the canister body 21 in the front-rear direction; the vehicle body structure assembly also includes a vehicle body floor 3, which has at least one first floor hole 301, and the mounting base 24 is connected to the lower surface of the vehicle body floor 3 and is disposed opposite to the at least one first floor hole 301.

[0085] By providing the mounting base 24, it is easier to install and connect structural components on the vehicle floor 3, thereby improving installation stability. For example, the seats inside the vehicle can be connected to the mounting base 24 by fasteners passing through the first floor hole 301, improving the strength and stability of the connection.

[0086] Optionally, refer to Figure 11 As shown, the mounting base 24 includes a mounting box 241, at least one second reinforcing plate 242, and at least one second threaded sleeve 243; the mounting box 241 is connected to the vehicle floor 3 and the gas tank body 21, the second reinforcing plate 242 is disposed inside the mounting box 241, and the second threaded sleeve 243 is connected to the mounting box 241 and disposed opposite to the first floor hole 301.

[0087] In this embodiment, the mounting box 241 provides a mounting base for the seat. For example, the rear side of the mounting box 241 can be welded to the front side of the gas tank body 21, and the upper side of the mounting box 241 can be welded to the lower surface of the vehicle floor 3, thereby improving the installation strength. A second reinforcing plate 242 is disposed inside the mounting box 241 to improve the overall structural strength of the mounting box 241. For example, after the bolts pass through the seat mounting holes on the seat inside the vehicle and the first floor hole 301 in sequence, a threaded connection with the second threaded sleeve 243 is achieved. The connection is convenient and has high strength, but this disclosure does not limit the specific connection method. In addition, the mounting box 241 can also withstand a portion of the impact in the front-rear direction of the vehicle, playing a good reinforcing role.

[0088] In another embodiment, refer to Figure 8 and Figure 9 As shown, the air spring canister 2 also includes at least one overlapping plate 25, which is connected to at least one side of the canister body 21 in the front-rear direction; the vehicle body structure assembly also includes a vehicle body floor 3, which has at least one second floor hole, and the overlapping plate 25 has at least one overlapping hole 250, which corresponds to and is disposed opposite to the overlapping hole 250.

[0089] In this embodiment, the overlapping plate 25 facilitates connection with the vehicle floor 3, improving the ease of connection. The overlapping plate 25 can be integrally formed on the rear side of the gas tank body 21 and connected to the aforementioned rear vehicle floor 32. For example, the overlapping plate 25 can overlap the aforementioned rear side panel flange 1122, and the rear side panel flange 1122 can overlap the rear vehicle floor 32. The overlapping hole 250 on the overlapping plate 25 is aligned with the flange opening 1123 on the rear side panel flange 1122 and the second floor hole on the rear vehicle floor 32, facilitating the insertion and connection of fasteners.
