Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a shock-absorbing and torsion-resistant component, a battery device, and a vehicle. Background Technology

[0002] Currently, an increasing number of vehicles are powered by battery packs. Existing battery packs are flexibly connected to the vehicle via shock-absorbing components, which reduces vibrations transmitted to the battery pack during vehicle operation, thereby extending the battery pack's lifespan. However, existing shock-absorbing components are difficult to replace once they fail or age. Summary of the Invention

[0003] In view of the above problems, this application provides a shock absorption and anti-torsion component, a battery device, and a vehicle, which can solve the problem that existing shock absorption components are difficult to replace after failure or aging.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a battery device, including: a battery housing with a first hanging ear on its outer periphery; a battery cell disposed within the battery housing; a shock-absorbing and anti-torsion assembly, including: a shock-absorbing assembly comprising an outer sleeve, an elastomer, and an inner bushing; the elastomer being disposed within the outer sleeve, and the inner bushing being disposed within the elastomer; a shock-absorbing and anti-torsion bracket, including a first shock-absorbing and anti-torsion bracket and a second shock-absorbing and anti-torsion bracket; the first shock-absorbing and anti-torsion bracket and the second shock-absorbing and anti-torsion bracket being detachably connected and forming an installation space; the outer sleeve being connected to the first shock-absorbing and anti-torsion bracket and at least partially located within the installation space; wherein, one of the inner bushing and the second shock-absorbing and anti-torsion bracket is connected to the first hanging ear.

[0005] When the damping and torsional anti-vibration components fail due to damage or aging, the connection between the first and second damping and torsional anti-vibration brackets is disconnected, and the first damping and torsional anti-vibration bracket and the damping components are disassembled and replaced, or the damping and torsional anti-vibration components are disassembled and replaced. This limitation not only allows for quick installation and replacement of damping components, improving installation efficiency, but also reduces production costs by eliminating the need for complete replacement. Furthermore, by replacing different damping components, the damping and torsional anti-vibration components can have varying degrees of torsional damping capabilities to meet different operating conditions, thereby improving versatility.

[0006] In some embodiments, the first shock-absorbing and torsion-resistant bracket has a through hole; the outer sleeve passes through the through hole and is fixedly connected to the side wall of the through hole. This limitation improves the stability of the outer sleeve connected to the first shock-absorbing and torsion-resistant bracket, thereby enhancing the robustness of the shock-absorbing assembly connected to the bracket.

[0007] In some embodiments, the second shock-absorbing and torsion-resistant bracket includes a side wall and a bottom wall; the side wall and bottom wall enclose an installation space; and a through hole communicates with the installation space. With the above limitations, the outer sleeve can at least partially be installed within the installation space through the through hole, further improving the stability of the outer sleeve connected to the first shock-absorbing and torsion-resistant bracket.

[0008] In some embodiments, the outer surface of the sidewall has a connecting lug; the first shock-absorbing and anti-torsion bracket also has a first mounting hole; the connecting lug has a second mounting hole, and the first shock-absorbing and anti-torsion bracket and the second shock-absorbing and anti-torsion bracket are detachably connected by fasteners passing through the first mounting hole and the second mounting hole. Through the above limitations, not only is the assembly and disassembly efficiency between the first shock-absorbing and anti-torsion bracket and the second shock-absorbing and anti-torsion bracket improved; but the structure is also simple and easy to operate and implement.

[0009] In some embodiments, the shock-absorbing and torsion-resistant bracket further includes a first limiting member located within the installation space; the first limiting member is disposed between the shock-absorbing component and the bottom wall. When the shock-absorbing component moves toward the second shock-absorbing and torsion-resistant bracket, the top surface of the first limiting member abuts against the bottom of the shock-absorbing component, thereby axially limiting the bottom of the elastomer, thus reducing the risk of tensile damage to the elastomer and improving the service life of the shock-absorbing component; at the same time, it can also reduce the risk of the shock-absorbing component directly colliding with the second shock-absorbing and torsion-resistant bracket.

[0010] In some embodiments, the first limiting member includes a suspended wall and two supporting walls; the two supporting walls are spaced apart on the bottom wall, and the suspended wall is suspended by the supporting walls. Through the above limitation, not only can the suspended wall achieve axial limiting of the bottom of the elastomer, but it can also form a suspended space to buffer the deformation of the suspended wall.

[0011] In some embodiments, the middle portion of the suspended wall bends away from the damping component to form a recess. With the above limitation, when the inner bushing moves downwards, the recess can accommodate the bottom of the inner bushing, allowing the bottom of the elastomer to first abut against the suspended walls on both sides of the recess. This reduces the probability of the inner bushing directly colliding with the first limiting member, thereby reducing the risk of damage to the inner bushing and the suspended wall.

[0012] In some embodiments, the bottom wall has a third mounting hole, through which a first bolt passes; one end of the first bolt is located between the bottom wall and the suspended wall, and is spaced apart from the suspended wall. Through the above-described limitations, not only can the shock-absorbing and torsional anti-parallel components be connected to the battery box or the vehicle body's mounting beam; but the structure is also simple and easy to install and operate; simultaneously, placing one end of the first bolt within the suspended space and spaced apart from the suspended wall protects the first bolt, thereby reducing the risk of damage to the first bolt and thus extending its service life.

[0013] In some embodiments, the damping and anti-torsion assembly further includes a second limiting member connected to the top end of the inner bushing. When the inner bushing moves a predetermined distance relative to the bottom end of the outer sleeve, the second limiting member abuts against the outer sleeve to restrict the axial movement of the inner bushing. This limitation enables axial positioning of the top of the elastomer, thereby reducing the risk of tensile damage to the elastomer and improving the service life of the damping assembly.

[0014] In some embodiments, the second limiting member includes: a second limiting plate; and a second limiting buffer pad disposed on the side edge of the second limiting plate facing the outer sleeve. When the inner bushing moves a predetermined distance relative to the bottom end of the outer sleeve, the second limiting buffer pad abuts against the top end of the outer sleeve. Through the above limitation, not only is the top of the elastomer axially limited, but the risk of damage due to direct collision between the second limiting plate and the outer sleeve is also reduced, as are abnormal noises.

[0015] In some embodiments, the outer sleeve includes: a first sleeve, fitted onto the outside of the elastomer and connected to the elastomer; and a second sleeve, fitted onto the outside of the first sleeve and engaged with the first sleeve by an interference fit. Through the above limitations, the disassembly and replacement of the first sleeve and the elastomer not only achieves versatility but also increases the number of disassembly and replacement methods, while also saving costs.

[0016] In some embodiments, the first sleeve includes an annular sidewall and a top wall, with the top wall fixedly connected to the top surface of the elastomer. This limitation not only enhances the bonding strength between the elastomer and the first sleeve, but also reduces the risk of the elastomer aging and failing due to rainwater immersion by covering part of the top wall of the elastomer.

[0017] In some embodiments, the top wall and the inner bushing are spaced apart, and the top surface of the elastomer has a first annular groove located between the top wall and the inner bushing. Through the above-described limitation, an edge region is formed between the side wall of the first annular groove near the inner bushing and the outer side wall of the inner bushing, which can improve the strength of the functional area between the middle of the elastomer and the middle of the inner bushing, thereby reducing the risk of tearing between the elastomer and the inner bushing, and thus increasing the service life of the damping assembly.

[0018] In some embodiments, the inner bushing has a protrusion in the middle, which is embedded in the elastomer. This limitation not only increases the contact area between the inner bushing and the elastomer, improving the bonding strength between them, but also changes the stress distribution, allowing it to withstand both pressure and shear forces, thereby reducing the risk of elastomer tearing.

[0019] In some embodiments, the bottom surface of the elastomer has a second annular groove. Through the aforementioned limitation, an edge region is formed between the side wall of the second annular groove near the inner bushing and the outer wall of the inner bushing. This enhances the strength of the functional area between the middle of the elastomer and the middle of the inner bushing, thereby reducing the risk of tearing between the elastomer and the inner bushing, and thus improving the service life of the damping assembly.

[0020] In some embodiments, the outer wall of the second annular groove bends outward and extends to the bottom surface of the outer sleeve. When the shock-absorbing assembly moves toward the second shock-absorbing torsion bracket or toward the first limiting member, the elastomer abuts against the second shock-absorbing torsion bracket or the first limiting member, which can reduce the probability of hard collision risk and thus improve the service life of the shock-absorbing assembly.

[0021] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a vehicle, including: a body, including a mounting beam; the aforementioned battery device, wherein the internal bushing of the battery device and another of the second shock-absorbing and anti-torsion bracket are connected to the mounting beam.

[0022] By using the aforementioned battery device, vehicles can quickly install and replace shock absorber components, improving installation efficiency; moreover, they do not need to replace all components, reducing production costs. Furthermore, by replacing different shock absorber components, the torsional damping components can have varying degrees of torsional damping capabilities to meet different operating conditions, thereby improving versatility.

[0023] In some embodiments, the inner bushing is connected to the mounting beam, and the second shock-absorbing and torsion-resistant bracket is connected to the first mounting lug. With the above limitations, the battery device can be at least partially mounted below the mounting beam.

[0024] To solve the above-mentioned technical problems, one technical solution adopted in this application is: providing a shock-absorbing and anti-torsion assembly, including: a shock-absorbing assembly, including an outer sleeve, an elastomer, and an inner bushing; the elastomer is disposed inside the outer sleeve, and the inner bushing is disposed inside the elastomer; a shock-absorbing and anti-torsion bracket, including a first shock-absorbing and anti-torsion bracket and a second shock-absorbing and anti-torsion bracket; the first shock-absorbing and anti-torsion bracket and the second shock-absorbing and anti-torsion bracket are detachably connected and enclose an installation space; the outer sleeve is connected to the first shock-absorbing and anti-torsion bracket and is at least partially located in the installation space; wherein, one of the inner bushing and the second shock-absorbing and anti-torsion bracket is connected to a first lug of the battery device.

[0025] By implementing the above limitations, not only can the vibration damping components be installed and replaced quickly, improving installation efficiency, but also, since not all components need to be replaced, production costs can be reduced. Furthermore, by replacing different vibration damping components, the vibration damping and torsional damping components can have different degrees of torsional damping function to meet the needs of different working conditions, thereby improving versatility.

[0026] In some embodiments, the second shock-absorbing and torsion-resistant bracket further includes a sidewall, the outer surface of which has a connecting lug; the first shock-absorbing and torsion-resistant bracket also has a first mounting hole; the connecting lug has a second mounting hole, and the first and second shock-absorbing and torsion-resistant brackets are detachably connected by fasteners passing through the first and second mounting holes. Through the above limitations, not only is the assembly and disassembly efficiency between the first and second shock-absorbing and torsion-resistant brackets improved; but the structure is also simple and easy to operate and implement.

[0027] In some embodiments, the damping and anti-torsion assembly further includes a second limiting member connected to the top end of the inner bushing. When the inner bushing moves a predetermined distance relative to the bottom end of the outer sleeve, the second limiting member abuts against the outer sleeve to restrict the axial movement of the inner bushing. This limitation enables axial positioning of the top of the elastomer, thereby reducing the risk of tensile damage to the elastomer and improving the service life of the damping assembly.

[0028] In some embodiments, the outer sleeve includes: a first sleeve, fitted onto the outside of the elastomer and connected to the elastomer; and a second sleeve, fitted onto the outside of the first sleeve and engaged with the first sleeve by an interference fit. Through the above limitations, the disassembly and replacement of the first sleeve and the elastomer not only achieves versatility but also increases the number of disassembly and replacement methods, while also saving costs.

[0029] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0050] Existing battery packs are flexibly connected to vehicles via shock absorber assemblies, which reduces vibrations transmitted to the battery pack during vehicle operation, thereby extending its lifespan. However, existing shock absorber assemblies are difficult to replace after failure or aging. This is because shock absorber assemblies typically consist of an outer sleeve, an elastomer, and an inner bushing, with both the outer sleeve and inner bushing fixedly connected to the elastomer. One of the battery pack and the vehicle's mounting beam is connected to the outer sleeve, and the other to the inner bushing. When a shock absorber assembly fails, it usually requires complete removal and replacement of the entire assembly from both the battery pack and the vehicle's mounting beam.

[0051] To address the problem of difficulty in replacing existing shock absorber components after failure or aging, this application, after in-depth research, provides a shock absorber and anti-torsion component, as well as a battery device and vehicle using this shock absorber and anti-torsion component. The shock absorber and anti-torsion component includes: a shock absorber assembly comprising an outer sleeve, an elastomer, and an inner bushing; the elastomer is disposed within the outer sleeve, and the inner bushing is disposed within the elastomer; a shock absorber and anti-torsion bracket comprising a first shock absorber and anti-torsion bracket and a second shock absorber and anti-torsion bracket; the first shock absorber and anti-torsion bracket and the second shock absorber and anti-torsion bracket are detachably connected and enclose an installation space; the outer sleeve is connected to the first shock absorber and anti-torsion bracket and is at least partially located within the installation space; wherein, one of the inner bushing and the second shock absorber and anti-torsion bracket is connected to a first lug.

[0052] This application allows for the disassembly and replacement of the first and second shock-absorbing torsion brackets, as well as the shock-absorbing components, by detaching the connection between them. This not only enables rapid installation and replacement of the shock-absorbing components, improving installation efficiency, but also reduces production costs by eliminating the need for complete replacement. Furthermore, by replacing different shock-absorbing components, the shock-absorbing torsion brackets can provide varying degrees of torsional damping capabilities to meet different operating conditions, thereby enhancing versatility.

[0053] See Figures 1 to 4 , Figure 1 This is a cross-sectional schematic diagram of a battery device according to one or more embodiments; Figure 2 This is a structural schematic diagram of a shock-absorbing and torsional-resistant assembly according to one or more embodiments; Figure 3 It is a side view of a shock-absorbing and torsional-resistant assembly according to one or more embodiments; Figure 4 yes Figure 3 The diagram shows a cross-sectional view of AA. This application provides a battery device. The battery device 100 includes a battery housing 10, a battery cell 20, and a shock-absorbing and anti-torsion assembly 30. A first hanging ear 110 is provided on the outer periphery of the battery housing 10. The battery cell 20 is disposed inside the battery housing 10. The shock-absorbing and anti-torsion assembly 30 includes a shock-absorbing component 31 and a shock-absorbing and anti-torsion bracket 32. The shock-absorbing component 31 includes an outer sleeve 311, an elastic body 312, and an inner bushing 313. The elastic body 312 is disposed inside the outer sleeve 311. The inner bushing 313 is disposed inside the elastic body 312. The shock-absorbing and anti-torsion bracket 32 ​​includes a first shock-absorbing and anti-torsion bracket 321 and a second shock-absorbing and anti-torsion bracket 322. The first shock-absorbing and anti-torsion bracket 321 and the second shock-absorbing and anti-torsion bracket 322 are detachably connected and enclose an installation space 3223. The outer sleeve 311 is connected to the first shock-absorbing and anti-torsion bracket 321 and is at least partially located in the installation space 3223. One of the inner bushing 313 and the second shock-absorbing and anti-torsion bracket 322 is connected to the first lug 110.

[0054] The battery housing 10 has a chamber for accommodating individual battery cells 20. The battery housing 10 may include a frame, a top wall, and a bottom wall. The frame is connected between the top and bottom walls and encloses the chamber. The shape of the battery housing 10 can be specifically designed as needed. For example, the shape of the battery housing 10 can be cylindrical, rectangular, etc. The arrangement of the individual battery cells 20 within the battery housing 10 is not limited.

[0055] The first hook 110 serves a connecting function. The first hook 110 is detachably or fixedly connected to the outer periphery of the battery case 10. The number of first hooks 110 can be, but is not limited to, one, two, or more than three. The first hook 110 can be connected to the shock-absorbing and anti-torsion assembly 30, so that the shock-absorbing and anti-torsion assembly 30 is connected to the outer periphery of the battery case 10, providing shock absorption and cushioning for the battery case 10. The number of shock-absorbing and anti-torsion assemblies 30 can be, but is not limited to, one, two, or more than three. When there are multiple shock-absorbing and anti-torsion assemblies 30, the multiple shock-absorbing and anti-torsion assemblies 30 are spaced apart on the outer periphery of the battery case 10. The number of first hooks 110 can be the same as or different from the number of shock-absorbing and anti-torsion assemblies 30. When the number of first lugs 110 is less than the number of shock-absorbing and anti-torsion components 30, multiple shock-absorbing and anti-torsion components 30 can be set on the first lugs 110; or, when the number of first lugs 110 corresponds to the number of shock-absorbing and anti-torsion components 30, the first lugs 110 can be connected one-to-one with the corresponding shock-absorbing and anti-torsion components 30, which is not limited here.

[0056] The outer sleeve 311 may be cylindrical. The outer sleeve 311 may be made of a rigid material. The rigid material may be, but is not limited to, metal or alloy materials. The interior of the outer sleeve 311 provides an installation position for the elastomer 312.

[0057] The elastomer 312 is disposed within the outer sleeve 311. The elastomer 312 provides an installation position for the inner bushing 313. The elastomer 312 may have a through hole (not shown in the figure). The through hole passes through the upper and lower ends of the elastomer 312. The elastomer 312 may be, but is not limited to, rubber, a spring, a nitrogen cylinder, an air spring, and related composite structures. The aforementioned rubber, spring, nitrogen cylinder, air spring, and related composite structures are conventional components and are not limited here. When the elastomer 312 is rubber, the rubber is vulcanized and fixed between the inner wall of the outer sleeve 311 and the outer wall of the inner bushing 313. When the elastomer 312 is of other structures, the elastomer 312 needs to be fixed within the outer sleeve 311, and the fixing method is not limited.

[0058] The inner bushing 313 may be a hollow tube. The inner bushing 313 may be made of a rigid material. The rigid material may be, but is not limited to, metal or alloy materials. The inner bushing 313 may be vulcanized and fixed within the elastomer 312.

[0059] The first damping and anti-torsion bracket 321 and the second damping and anti-torsion bracket 322 can be made of rigid materials. Rigid materials can be, but are not limited to, metal and alloy materials. The first damping and anti-torsion bracket 321 and the second damping and anti-torsion bracket 322 can be connected by, but are not limited to, snap-fit, plug-in, and bolt connections. The installation space 3223 provides an installation position for the aforementioned damping component 31. The outer sleeve 311 is detachably or fixedly connected to the outer periphery of the first damping and anti-torsion bracket 321. In this embodiment, the outer sleeve 311 is welded to or integrally formed onto the outer periphery of the first damping and anti-torsion bracket 321. The outer sleeve 311 may be partially located within the installation space 3223 and partially located outside the installation space 3223; or, the entire outer sleeve 311 may be located within the installation space 3223.

[0060] In this assembly, one of the inner bushing 313 and the second shock-absorbing and anti-torsion bracket 322 is connected to the first hook 110, enabling the shock-absorbing and anti-torsion assembly 30 to be connected to the outer periphery of the battery housing 10. The inner bushing 313 of the shock-absorbing and anti-torsion assembly 30 is connected to the first hook 110. Alternatively, the second shock-absorbing and anti-torsion bracket 322 of the shock-absorbing and anti-torsion assembly 30 is connected to the first hook 110. The connection method can be, but is not limited to, detachable or fixed connections.

[0061] When the shock-absorbing and anti-torsion component 30 fails due to damage or aging, disconnect the connection between the first shock-absorbing and anti-torsion bracket 321 and the second shock-absorbing and anti-torsion bracket 322, disassemble and replace the first shock-absorbing and anti-torsion bracket 321 and the shock-absorbing component 31, or disassemble and replace the shock-absorbing and anti-torsion component 30.

[0062] By implementing the above limitations, not only can the vibration damping components 31 be installed and replaced quickly, improving installation efficiency, but also, since they do not need to be replaced entirely, production costs can be reduced. Furthermore, by replacing different vibration damping components 31, the vibration damping and torsional anti-vibration components 30 can have different degrees of torsional damping function to meet the needs of different working conditions, thereby improving versatility.

[0063] Please see Figure 5 , Figure 5 This is a schematic diagram of a first partial cross-section of a shock-absorbing and torsional-resistant assembly according to one or more embodiments. (Combined with...) Figures 1 to 4 In some embodiments, the first shock-absorbing and anti-torsion bracket 321 has a through hole 3211. An outer sleeve 311 passes through the through hole 3211. The outer side wall of the outer sleeve 311 is fixedly connected to the side wall of the through hole 3211.

[0064] The through hole 3211 provides an installation position for the outer sleeve 311. The shape and size of the through hole 3211 can match the shape and size of the outer sleeve 311, improving the stability of the connection between the outer sleeve 311 and the through hole 3211. The fixing method between the outer wall of the outer sleeve 311 and the side wall of the through hole 3211 can be, but is not limited to, welding. Alternatively, the outer wall of the outer sleeve 311 and the first shock-absorbing anti-torsion bracket 321 can be integrally formed and connected. When it is necessary to replace the shock-absorbing component 31, the first shock-absorbing anti-torsion bracket 321 and the shock-absorbing component 31 can be replaced as a whole.

[0065] By limiting the connection between the outer sleeve 311 and the first shock-absorbing and anti-torsion bracket 321, the stability of the connection between the shock-absorbing component 31 and the shock-absorbing and anti-torsion bracket 32 ​​is improved, thereby enhancing the robustness of the connection between the shock-absorbing component 31 and the shock-absorbing and anti-torsion bracket 32.

[0066] In other embodiments, the outer wall of the outer sleeve 311 and the side wall of the through hole 3211 can be, but are not limited to, interference fit or interference fit, as long as the outer sleeve 311 is stably fixed to the through hole 3211.

[0067] like Figure 5 In some embodiments, the second shock-absorbing and torsion-resistant bracket 322 includes a side wall 3221 and a bottom wall 3222. An installation space 3223 is formed between the side wall 3221 and the bottom wall 3222. A through hole 3211 communicates with the installation space 3223.

[0068] The side wall 3221 and the bottom wall 3222 are detachably or fixedly connected. In this embodiment, the side wall 3221 and the bottom wall 3222 are integrally formed. The mounting space 3223 can be a groove formed by bending or stamping. For example, the mounting space 3223 is a U-shaped groove formed by a bottom wall 3222 and two side walls 3221. This mounting space 3223 can accommodate at least a portion of the outer sleeve 311. The through hole 3211 is located above the mounting space 3223. After passing through the through hole 3211, the outer sleeve 311 is partially accommodated within the mounting space 3223; a portion of the outer sleeve 311 passes through the through hole 3211 and is located outside the mounting space 3223.

[0069] With the above limitations, the outer sleeve 311 can be installed in the installation space 3223 at least partially through the through hole 3211, further improving the stability of the outer sleeve 311 connected to the first shock-absorbing and anti-torsion bracket 321.

[0070] The first shock-absorbing and anti-torsion bracket 321 and the second shock-absorbing and anti-torsion bracket 322 can be connected by, but not limited to, snap-fit, plug-in, and bolt connections.

[0071] Please see Figure 6 , Figure 6 yes Figure 4 A magnified view of part B shown. Combined with... Figures 1 to 5 In some embodiments, the outer surface of the sidewall 3221 has a connecting lug 3224. The first shock-absorbing and anti-torsion bracket 321 also has a first mounting hole 3212. The connecting lug 3224 has a second mounting hole 32241. The first shock-absorbing and anti-torsion bracket 321 and the second shock-absorbing and anti-torsion bracket 322 are detachably connected by a fastener 323 passing through the first mounting hole 3212 and the second mounting hole 32241.

[0072] The connecting ear 3224 is a component extending outward from the sidewall 3221, used for connection. The connecting ear 3224 is detachably or fixedly connected to the outer surface of the sidewall 3221. In this embodiment, the connecting ear 3224 is integrally formed on the outer surface of the sidewall 3221. The number of connecting ears 3224 can be, but is not limited to, one, two, or more than three. In this embodiment, two connecting ears 3224 are provided on the outer surface of the sidewall 3221. The number of the first mounting hole 3212, the second mounting hole 32241, and the fixing member 323 corresponds one-to-one. Furthermore, the first mounting hole 3212 and the second mounting hole 32241 correspond one-to-one. For example, the first mounting hole 3212 and the second mounting hole 32241 are arranged vertically opposite each other. The fixing member 323 can be, but is not limited to, fixing bolts and fixing nuts.

[0073] The above limitations not only improve the efficiency of disassembly and assembly between the first shock-absorbing and anti-torsion bracket 321 and the second shock-absorbing and anti-torsion bracket 322, but also make the structure simple and easy to operate.

[0074] In other embodiments, the first shock-absorbing and anti-torsion bracket 321 and the connecting ear 3224 may also be connected by, but not limited to, snap-fit ​​structures and plug-in structures, which are not limited here.

[0075] See Figure 4 and Figure 5 In some embodiments, the shock-absorbing and torsion-resistant bracket 32 ​​further includes a first limiting member 33 located within the installation space 3223. The first limiting member 33 is disposed between the shock-absorbing component 31 and the bottom wall 3222.

[0076] The first limiting member 33 is detachable or fixed between the shock-absorbing component 31 and the bottom wall 3222. In this embodiment, the first limiting member 33 is fixed between the shock-absorbing component 31 and the bottom wall 3222.

[0077] When the shock absorber 31 moves toward the second shock absorber anti-torsion bracket 322, the top surface of the first limiting member 33 abuts against the bottom of the shock absorber 31, thereby axially limiting the bottom of the elastic body 312, thus reducing the risk of tensile damage to the elastic body 312 and improving the service life of the shock absorber 31; at the same time, it can also reduce the risk of the shock absorber 31 directly colliding with the second shock absorber anti-torsion bracket 322.

[0078] The first limiting member 33 is disposed between the shock-absorbing component 31 and the bottom wall 3222, wherein the first limiting member 33 can be connected to at least one of the bottom wall 3222, the side wall 3221 and the first shock-absorbing anti-torsion bracket 321.

[0079] In some embodiments, the first limiting member 33 is connected to the bottom wall 3222. The first limiting member 33 includes a suspended wall 331 and two supporting walls 332. The two supporting walls 332 are spaced apart on the bottom wall 3222. The suspended wall 331 is suspended through the supporting walls 332.

[0080] In this embodiment, one end of the suspended wall 331 is connected to the upper end of a supporting wall 332, and the other end of the suspended wall 331 is connected to the upper end of another supporting wall 332. The lower ends of both supporting walls 332 and the other supporting wall 332 are connected to the bottom wall 3222. One end of each supporting wall 332 is detachably or fixedly connected to the bottom wall 3222; the other end is detachably or fixedly connected to the end of the suspended wall 331. In this embodiment, the two supporting walls 332 and the suspended wall 331 are integrally formed and connected; and the two supporting walls 332 are welded to the bottom wall 3222. A suspended space 333 is formed between the two supporting walls 332, the suspended wall 331, and the bottom wall 3222.

[0081] Through the above limitations, not only can the suspended wall 331 achieve axial positioning of the bottom of the elastic body 312, but it can also form a suspended space 333 to buffer the deformation of the suspended wall 331.

[0082] In other embodiments, both support walls 332 of the first limiting member 33 are connected to the bottom surface of the first shock-absorbing and anti-torsion bracket 321. The first limiting member 33 wraps around the outer periphery of the shock-absorbing assembly 31.

[0083] In some other embodiments, both support walls 332 of the first limiting member 33 are connected to the corresponding side wall 3221. Alternatively, one of the two support walls 332 of the first limiting member 33 is connected to the bottom wall 3222 and the other is connected to the side wall 3221.

[0084] The first limiting member 33 may be provided with a first limiting buffer pad (not shown in the figure) on the side facing the shock absorption component 31. The first limiting buffer pad can play a buffering role, which can not only reduce the probability of damage caused by direct collision between the shock absorption component 31 and the first limiting member 33, but also reduce the occurrence of abnormal noise problems.

[0085] The aforementioned first limiting buffer pad is detachably or fixedly connected to the surface of the first limiting member 33 facing the outer sleeve 311. In this embodiment, the first limiting buffer pad is fixed to the first limiting member 33. The first limiting buffer pad can be, but is not limited to, a rubber pad or a silicone pad.

[0086] See also Figure 4 and Figure 5 In some embodiments, the middle part of the suspended wall 331 is bent toward the side away from the damping component 31 to form a recess 3311.

[0087] The recessed portion 3311 is groove-shaped. The recessed portion 3311 can be integrally formed at the middle position of the suspended wall 331. The recessed portion 3311 is provided at the bottom of the inner bushing 313, and its area is larger than the bottom area of ​​the inner bushing 313.

[0088] With the above limitations, when the inner bushing 313 moves downward, the recess 3311 can accommodate the bottom of the inner bushing 313, so that the bottom of the elastic body 312 first abuts against the suspended walls 331 on both sides of the recess 3311, which can reduce the probability of the inner bushing 313 directly colliding with the first limiting member 33, thereby reducing the risk of damage to the inner bushing 313 and the suspended walls 331.

[0089] In some embodiments, the bottom wall 3222 has a third mounting hole 32221. A first bolt 35 passes through the third mounting hole 32221. One end of the first bolt 35 is located between the bottom wall 3222 and the suspended wall 331; the other end of the first bolt 35 is spaced apart from the suspended wall 331.

[0090] One end of the first bolt 35 is located within the suspended space 333. The other end of the first bolt 35 is used to connect with the first lug 110 or the mounting beam 1100. The number of the third mounting holes 32221 corresponds to the number of the first bolts 35. The number of the third mounting holes 32221 and the number of the first bolts 35 can be, but is not limited to, one, two, or more than three. In this embodiment, the number of the third mounting holes 32221 and the number of the first bolts 35 are both two, which can improve the stability of the second shock-absorbing and anti-torsion bracket 322 connected to the first lug 110 or the mounting beam 1100.

[0091] The above-mentioned limitations not only enable the shock-absorbing and anti-torsion assembly 30 to be connected to the battery box 10 or the vehicle body mounting beam 1100, but also make the structure simple and easy to install and operate. At the same time, placing one end of the first bolt 35 in the suspended space 333 and spaced apart from the suspended wall 331 can protect the first bolt 35, thereby reducing the risk of damage to the first bolt 35 and improving its service life.

[0092] Please see Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of a second partial cross-section of a shock-absorbing and torsional-resistant assembly according to one or more embodiments; Figure 8 yes Figure 7 A magnified view of part C shown. Combined with... Figures 1 to 6 In some embodiments, the shock-absorbing and anti-torsion assembly 30 further includes a second limiting member 34. The second limiting member 34 is connected to the top end of the inner bushing 313. When the inner bushing 313 moves a predetermined distance relative to the outer sleeve 311 toward the bottom end of the outer sleeve 311, the second limiting member 34 abuts against the outer sleeve 311 to restrict the axial movement of the inner bushing 313.

[0093] The second limiting member 34 is detachably or fixedly connected to the top end of the inner bushing 313. In this embodiment, the second limiting member 34 is fixedly connected to the top end of the inner bushing 313.

[0094] By limiting the elastic body 312 as described above, the top of the elastic body 312 can be axially restricted, thereby reducing the risk of tensile damage to the elastic body 312 and thus improving the service life of the damping component 31.

[0095] In some embodiments, the second limiting member 34 includes a second limiting plate 341 and a second limiting buffer pad 342. The second limiting buffer pad 342 is disposed on one side edge of the second limiting plate 341 facing the outer sleeve 311. When the inner bushing 313 moves a predetermined distance relative to the bottom end of the outer sleeve 311, the second limiting buffer pad 342 abuts against the top end of the outer sleeve 311.

[0096] The second limiting buffer pad 342 serves a cushioning function. The second limiting buffer pad 342 is detachably or fixedly connected to the surface of the second limiting plate 341 facing the outer sleeve 311. In this embodiment, the second limiting buffer pad 342 is fixed to the second limiting plate 341. The second limiting buffer pad 342 can be, but is not limited to, a rubber pad or a silicone pad.

[0097] By limiting the elastic body 312 axially, the risk of damage caused by direct collision between the second limiting plate 341 and the outer sleeve 311 can be reduced, as well as abnormal noise.

[0098] See Figure 7 and Figure 8 In some embodiments, the outer sleeve 311 includes a first sleeve 3113 and a second sleeve 3114. The first sleeve 3113 is sleeved on the outside of the elastic body 312 and is connected to the elastic body 312. The second sleeve 3114 is sleeved on the outside of the first sleeve 3113. The second sleeve 3114 and the first sleeve 3113 are engaged by an interference fit.

[0099] Both the first sleeve 3113 and / or the second sleeve 3114 can be cylindrical. The first sleeve 3113 and / or the second sleeve 3114 can be made of rigid material. Rigid material can be, but is not limited to, metal and alloy materials. The interior of the first sleeve 3113 provides an installation position for the elastomer 312. The elastomer 312 can be fixedly connected between the first sleeve 3113 and the inner bushing 313. For example, the elastomer 312 can be vulcanized and fixed between the first sleeve 3113 and the inner bushing 313.

[0100] By implementing the above limitations, the disassembly and replacement of the first sleeve 3113 and the elastomer 312 not only achieves versatility, but also increases the number of disassembly and replacement methods, and saves costs.

[0101] In some embodiments, the first sleeve 3113 includes an annular sidewall 3111 and a top wall 3112. The top wall 3112 is fixedly connected to the top surface of the elastomer 312.

[0102] The annular sidewall 3111 and the top wall 3112 are detachably or fixedly connected. In this embodiment, the annular sidewall 3111 and the top wall 3112 are integrally formed. The top wall 3112 can be fixed to the top surface of the elastomer 312 by vulcanization, but is not limited to vulcanization.

[0103] The above-mentioned limitations not only enhance the bonding strength between the elastomer 312 and the first sleeve 3113, but also reduce the risk of the elastomer 312 aging and failing due to rainwater immersion by the top wall 3112 covering part of the top wall of the elastomer 312.

[0104] In some embodiments, the top wall 3112 and the inner bushing 313 are spaced apart. The top surface of the elastomer 312 has a first annular groove 3121. The first annular groove 3121 is located between the top wall 3112 and the inner bushing 313.

[0105] The first annular groove 3121 is recessed. Alternatively, the first annular groove 3121 can be annular. The first annular groove 3121 can be integral; or, the first annular groove 3121 can be spaced apart.

[0106] With the above-mentioned limitations, an edge region is formed between the side wall of the first annular groove 3121 near the inner bushing 313 and the outer wall of the inner bushing 313, which can improve the strength of the functional area between the middle of the elastomer 312 and the middle of the inner bushing 313, thereby reducing the risk of tearing between the elastomer 312 and the inner bushing 313, and thus improving the service life of the shock absorption assembly 31.

[0107] In some embodiments, the inner bushing 313 has a protrusion 3131 at its center. The protrusion 3131 is embedded within the elastomer 312.

[0108] The protrusion 3131 is detachably or fixedly connected to the outer periphery of the middle portion of the inner bushing 313. In this embodiment, the protrusion 3131 is integrally formed on the outer periphery of the middle portion of the inner bushing 313. The protrusion 3131 may be arranged in a ring shape.

[0109] By limiting the above, not only can the contact area between the inner bushing 313 and the elastomer 312 be increased, and the bonding strength between the inner bushing 313 and the elastomer 312 be improved, but the stress mode can also be changed, that is, it can be subjected to pressure and shear force, thereby reducing the risk of tearing of the elastomer 312.

[0110] In some embodiments, the bottom surface of the elastomer 312 has a second annular groove 3122.

[0111] The second annular groove 3122 is recessed. The second annular groove 3122 can be integral; alternatively, it can be spaced apart. The depths of the first annular groove 3121 and the second annular groove 3122 can be the same or different. In this embodiment, the depth of the first annular groove 3121 is greater than the depth of the second annular groove 3122. Furthermore, the first annular groove 3121 and the second annular groove 3122 can both be annular. The radial dimension of the first annular groove 3121 is smaller than the radial dimension of the second annular groove 3122.

[0112] With the above-mentioned limitations, the side wall of the second annular groove 3122 near the inner bushing 313 forms an edge region between the outer wall of the inner bushing 313 and the inner bushing 313, which can improve the strength of the functional area between the middle of the elastomer 312 and the middle of the inner bushing 313, thereby reducing the risk of tearing between the elastomer 312 and the inner bushing 313, and thus improving the service life of the shock absorption assembly 31.

[0113] In some embodiments, the outer wall of the second annular groove 3122 bends outward and extends to the bottom surface of the outer sleeve 311.

[0114] The bottom of the elastomer 312 protrudes from the bottom surface of the outer sleeve 311.

[0115] When the shock absorber 31 moves toward the second shock absorber and anti-torsion bracket 322 or toward the first limiting member 33, the elastic body 312 abuts against the second shock absorber and anti-torsion bracket 322 or the first limiting member 33, which can reduce the probability of hard collision risk and thus improve the service life of the shock absorber 31.

[0116] Please see Figure 9 , Figure 9 This is an exploded view of a single battery cell according to one or more embodiments. (Combined with...) Figures 1 to 8 The battery cell 20 can be a rechargeable battery, which refers to a battery cell 20 that can be recharged after discharge to activate the active materials and continue to be used. The battery cell 20 can include, but is not limited to, lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, etc.

[0117] In some embodiments, the battery cell 20 may include a housing 206, an electrode assembly 205, and a cover 202. The housing 206 has a communicating cavity and a mounting port. The number of electrode assemblies 205 may be one or more; the electrode assemblies 205 are mounted within the cavity of the housing 206. The cover 202 is connected to the housing 206 and covers the mounting port. The housing 206 is filled with an electrolyte, such as an electrolyte solution.

[0118] The electrode assembly 205 may include an anode electrode and a cathode electrode, as well as a separator disposed between the anode electrode and the cathode electrode. During the charging and discharging process of the battery cell 20, active ions (e.g., lithium ions) repeatedly insert and extract between the anode electrode and the cathode electrode. The separator can, to some extent, prevent short circuits between the anode electrode and the cathode electrode, while allowing active ions to pass through. The battery cell 20 may also include a safety valve 204 (also called a pressure relief valve), two terminals 203, and two connecting members 201 (also called current collectors). The safety valve 204 may be disposed on the cover plate 202, for example, the safety valve 204 may be fixed to the cover plate 202. The safety valve 204 is used to brake and release the internal electrolyte when the internal pressure or temperature of the battery cell 20 reaches a threshold, thereby reducing the internal pressure or temperature of the battery cell 20. For example, the safety valve 204 may be a temperature-sensitive valve, a pressure-sensitive valve, etc. Two terminals 203 can be disposed on the cover plate 202, namely the positive terminal and the negative terminal, and each terminal 203 is connected to a corresponding connecting member 201. The connecting member 201 is located between the cover plate 202 and the electrode assembly 205, and is used to electrically connect the electrode assembly 205 and the terminal 203. The housing 206 is a hollow structure, and the material of the housing 206 can be metal or plastic; for example, the material of the housing 206 can be copper, iron, aluminum, steel, aluminum alloy, etc.

[0119] Please see Figure 10 , Figure 10 This is a structural schematic diagram of a vehicle based on one or more embodiments. (Combined with...) Figures 1 to 9 This application provides a vehicle. The vehicle 1000 can be, but is not limited to, a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be, but are not limited to, pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles. A battery device 100 is installed inside the vehicle 1000. The battery device 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery device 100 can be used to power the vehicle 1000. For example, the battery device 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the power supply from the battery device 100 to the motor 300. For example, this controls the power requirements for starting, navigating, and driving the vehicle 1000. The battery device 100 can not only serve as the operating power source for the vehicle 1000 but also as the driving power source for the vehicle 1000, replacing or partially replacing gasoline or natural gas to provide driving power for the vehicle 1000.

[0120] Vehicle 1000 includes a body (not shown in the figure) and the aforementioned battery device 100. The body includes a mounting beam 1100. An inner bushing 313 in the battery device 100 and another of the second shock-absorbing and torsion-resistant brackets 322 are connected to the mounting beam 1100 of the body so that the battery device 100 is connected to the body via the shock-absorbing and torsion-resistant assembly 30.

[0121] During vehicle 1000 operation, vibrations generated by the vehicle body are transmitted through the mounting beam 1100 to the shock-absorbing and torsion-resistant assembly 30, and then through the shock-absorbing and torsion-resistant assembly 30 to the battery box 10. The shock-absorbing and torsion-resistant assembly 30 plays a role in shock absorption and torsion resistance, reducing the vibration and torsion generated by the battery box 10 and its internal battery cells 20 along with the mounting beam 1100. It should be noted that in this embodiment, the battery device 100 is the same as the battery device 100 described in the above embodiments, and will not be repeated here.

[0122] By using the aforementioned battery device 100, the vehicle can not only quickly install and replace the shock absorber components 31, improving installation efficiency, but also reduce production costs by eliminating the need for complete replacement. Furthermore, by replacing different shock absorber components 31, the shock absorber torsional damping components 30 can have varying degrees of torsional damping function to meet different operating conditions, thereby improving versatility.

[0123] The first mounting lug 110 can be connected to the inner bushing 313 or the second shock-absorbing and anti-torsion bracket 322. The mounting beam 1100 can be connected to the second shock-absorbing and anti-torsion bracket 322 or the inner bushing 313. The positions of the first mounting lug 110 and the mounting beam 1100 on the inner bushing 313 and the second shock-absorbing and anti-torsion bracket 322 can be determined according to the actual situation and are not limited here.

[0124] In some embodiments, the inner bushing 313 of the shock-absorbing and torsion-resistant assembly 30 is connected to the vehicle body's mounting beam 1100. The second shock-absorbing and torsion-resistant bracket 322 of the shock-absorbing and torsion-resistant assembly 30 is connected to the first lug 110 of the battery box 10.

[0125] The inner bushing 313 is detachably connected to the mounting beam 1100. For example, the inner bushing 313 is connected to the mounting beam 1100 via a second bolt 36. The second shock-absorbing and anti-torsion bracket 322 is detachably connected to the first lug 110. For example, the second shock-absorbing and anti-torsion bracket 322 is connected to the first lug 110 via a first bolt 35.

[0126] With the above limitations, the battery device 100 can be at least partially mounted below the mounting beam 1100.

[0127] In other embodiments, the inner bushing 313 of the shock-absorbing and torsion-resistant assembly 30 is connected to the first lug 110 of the battery box 10. The second shock-absorbing and torsion-resistant bracket 322 of the shock-absorbing and torsion-resistant assembly 30 is connected to the vehicle body's mounting beam 1100.

[0128] The inner bushing 313 is detachably connected to the first lug 110. For example, the inner bushing 313 is connected to the first lug 110 via a second bolt 36. The second shock-absorbing and anti-torsion bracket 322 is detachably connected to the mounting beam 1100. For example, the second shock-absorbing and anti-torsion bracket 322 is connected to the mounting beam 1100 via a first bolt 35.

[0129] With the above constraints, the battery device 100 is at least partially supported above the mounting beam 1100.

[0130] In some embodiments, the inner bushing 313 is provided with a bushing hole 3132. The second limiting plate 341 is provided with a limiting hole (not shown in the figure). The second bolt 36 passes through the bushing hole 3132 and the limiting hole in sequence, so that the shock-absorbing and anti-torsion assembly 30 is connected to the mounting beam 1100 or the first lug 110.

[0131] When the inner bushing 313 is connected to the mounting beam 1100 or the first hanging lug 110 by the second bolt 36, the second limiting plate 341 can also play a certain supporting role, so that the shock-absorbing and anti-torsion assembly 30 is more stably connected to the mounting beam 1100 or the first hanging lug 110.

[0132] See Figures 1 to 10 This application provides a shock-absorbing and torsion-resistant assembly. The shock-absorbing and torsion-resistant assembly 30 includes a shock-absorbing component 31 and a shock-absorbing and torsion-resistant bracket 32. The shock-absorbing component 31 includes an outer sleeve 311, an elastic body 312, and an inner bushing 313. The elastic body 312 is disposed within the outer sleeve 311. The inner bushing 313 is disposed within the elastic body 312. The shock-absorbing and torsion-resistant bracket 32 ​​includes a first shock-absorbing and torsion-resistant bracket 321 and a second shock-absorbing and torsion-resistant bracket 322. The first shock-absorbing and torsion-resistant bracket 321 and the second shock-absorbing and torsion-resistant bracket 322 are detachably connected and form an installation space 3223. The outer sleeve 311 is connected to the first shock-absorbing and torsion-resistant bracket 321 and is at least partially located in the installation space 3223. One of the inner bushing 313 and the second shock-absorbing and torsion-resistant bracket 322 is connected to a first lug 110 of the battery device 100.
