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 prone to internal structural damage and failure during use, further reducing their lifespan. Utility Model Content

[0003] In view of the above problems, this application provides a shock-absorbing and torsion-resistant component, a battery device, and a vehicle, which can solve the problems of existing shock-absorbing components being prone to internal structural damage and failure during use, thereby reducing their service life.

[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 in the battery housing; a shock-absorbing and anti-torsion assembly, including: an outer sleeve; an elastic body disposed in the outer sleeve; the elastic body having a through hole; an inner bushing disposed in the through hole; one of the outer sleeve and the inner bushing being connected to the first hanging ear; wherein, the top surface of the elastic body has a first annular groove, and / or, the bottom surface of the elastic body has a second annular groove.

[0005] The top surface of the elastomer has a first annular groove; and / or the bottom surface of the elastomer has a second annular groove, which enables the bonding force between the middle part of the elastomer and the middle part of the outer sleeve to be greater than the bonding force between the top of the elastomer and the top of the outer sleeve; and / or enables the bonding force between the middle part of the elastomer and the middle part of the outer sleeve to be greater than the bonding force between the bottom of the elastomer and the bottom of the outer sleeve, thereby reducing the risk of elastomer tearing, thereby increasing the bonding force between the middle part of the elastomer and the middle part of the outer sleeve, and thus increasing the service life of the shock absorption and anti-torsion assembly, etc.

[0006] In some embodiments, the top end of the outer sidewall of the first annular groove is flush with the top end of the outer sleeve, and the top end of the inner sidewall of the first annular groove is flush with the top end of the inner bushing; and / or the bottom end of the outer sidewall of the second annular groove is flush with the bottom end of the outer sleeve, and the bottom end of the inner sidewall of the second annular groove is flush with the bottom end of the inner bushing. By these limitations, the bonding force between the upper outer sidewall of the elastomer and the upper inner sidewall of the outer sleeve is improved, as is the bonding force between the upper inner sidewall of the elastomer and the upper outer sidewall of the inner bushing; and / or, the bonding force between the lower outer sidewall of the elastomer and the lower inner sidewall of the outer sleeve is improved, as well as the bonding force between the lower inner sidewall of the elastomer and the lower outer sidewall of the inner bushing is improved, thereby reducing the risk of elastomer tearing, etc.

[0007] In some embodiments, the top end of the inner bushing protrudes beyond the top end of the outer sleeve; and / or the bottom end of the inner bushing protrudes beyond the bottom end of the outer sleeve. These limitations not only enhance the bonding strength between the inner bushing and the elastomer but also provide mounting positions for subsequent limiting components and the first bolt, etc.

[0008] In some embodiments, the depth of the first annular groove is 3%-5% of the length of the elastomer; and / or the depth of the second annular groove is 3%-5% of the length of the elastomer. By defining these dimensions, not only can the edge region formed between the upper part of the elastomer and the upper part of the outer sleeve be sufficiently large; and / or, the edge region formed between the lower part of the elastomer and the lower part of the outer sleeve be sufficiently large, thereby improving the strength of the functional area between the middle part of the elastomer and the middle part of the outer sleeve, but also reducing usage costs, etc.

[0009] In some embodiments, the damping and anti-torsion assembly includes a limiting component connected to the inner bushing. The limiting component is configured such that when the inner bushing moves axially a predetermined distance relative to the outer sleeve, the limiting component abuts against the outer sleeve to restrict the movement of the inner bushing relative to the outer sleeve. This limitation enables axial positioning of the elastomer, thereby reducing the risk of tensile damage to the elastomer and improving the service life of the damping and anti-torsion assembly.

[0010] In some embodiments, the limiting component includes a first limiting component connected to the top end of the inner bushing; when the inner bushing moves a predetermined distance relative to the outer sleeve towards the bottom end of the outer sleeve, the first limiting component abuts against the top end of the outer sleeve to restrict the axial movement of the inner bushing; and / or the limiting component includes a second limiting component connected to the bottom end of the inner bushing; when the inner bushing moves a predetermined distance relative to the outer sleeve towards the top end of the outer sleeve, the second limiting component abuts against the bottom end of the outer sleeve to restrict the axial movement of the inner bushing. Through the above limitations, axial limiting of the top of the elastomer and / or axial limiting of the bottom of the elastomer can be achieved, thereby reducing the risk of tensile damage to the elastomer and thus improving the service life of the shock-absorbing and anti-torsion component.

[0011] In some embodiments, the first limiting component includes: a first limiting plate, including a first limiting portion; a first limiting buffer pad disposed on the surface of the first limiting portion facing the outer sleeve; when the inner bushing moves a predetermined distance relative to the outer sleeve towards the bottom end of the outer sleeve, the first limiting buffer pad abuts against the top end of the outer sleeve; and / or the second limiting component includes: a second limiting plate, including a second limiting portion; a second limiting buffer pad disposed on the surface of the second limiting portion facing the outer sleeve; when the inner bushing moves a predetermined distance relative to the outer sleeve towards the top end of the outer sleeve, the second limiting buffer pad abuts against the bottom end of the outer sleeve. Through the above limitations, not only is axial limiting of the top of the elastomer achieved; and / or axial limiting of the bottom of the elastomer achieved, but the risk of damage due to direct collision between the first limiting portion and the outer sleeve is also reduced; and / or the risk of damage due to direct collision between the second limiting portion and the outer sleeve is also reduced; at the same time, abnormal noises can also be reduced.

[0012] In some embodiments, the first limiting component includes a first limiting plate, which includes a first limiting portion; wherein the circumferential edge of the first limiting plate forms the first limiting portion, and the central region of the first limiting plate is recessed towards the inner bushing to form a connecting portion; a first limiting buffer pad is disposed around the connecting portion; the connecting portion is connected to the top end of the inner bushing. Through the above limitations, not only is the contact area between the first limiting buffer pad and the top end of the outer sleeve increased, but the first limiting plate is also installed on the top end of the inner bushing, while also providing an installation position for the subsequent installation of the first bolt.

[0013] In some embodiments, the inner bushing has a first connecting hole, the bottom wall of the connecting part has a second connecting hole communicating with the first connecting hole, and the second limiting plate has a third connecting hole communicating with the first connecting hole. Through the above limitations, not only is the stability of the first limiting plate locked to the top of the inner bushing and the stability of the second limiting plate locked to the top of the inner bushing improved, but the shock-absorbing and torsion-resistant assembly can also be connected to the first lug or the mounting beam.

[0014] In some embodiments, the top of the inner bushing has a first mounting groove, and the connecting portion is embedded in the first mounting groove. This limitation improves the stability of the first limiting plate connected to the inner bushing; it also reduces the size of the shock-absorbing and anti-torsion assembly in the first direction.

[0015] In some embodiments, one of the bottom wall of the connecting portion and the bottom wall of the first mounting groove has a first snap-fit ​​portion, and the other has a first snap-fit ​​groove, with the first snap-fit ​​portion engaging with the first snap-fit ​​groove. Through the above-described limitations, not only is the first limiting plate connected to the top of the inner bushing, but the structure is also simple and easy to install and operate.

[0016] In some embodiments, the limiting component includes a first limiting component, and the outer sleeve includes an annular sidewall and two second lugs disposed on the outer surface of the annular sidewall. The end of each second lug away from the annular sidewall forms a mounting portion with a mounting hole, which is higher than the first limiting component. The outer sleeve is connected to the first lug or a mounting beam, etc., through the mounting holes in the mounting portions of the two second lugs. This not only ensures that the second lugs of the outer sleeve are stably connected to the first lug or mounting beam, but also provides a simple structure and ease of installation and operation. Furthermore, the mounting portion being higher than the first limiting component reduces the risk of the first limiting component colliding with the first lug or mounting beam, thereby improving the service life of the shock-absorbing and torsional anti-vibration component.

[0017] In some embodiments, the surface of the first limiting component facing the outer sleeve is provided with a first annular protrusion; during the rest and movement of the inner bushing relative to the outer sleeve, the first annular protrusion remains in contact with the inner or outer wall surface of the outer sleeve; and / or the surface of the second limiting component facing the outer sleeve is provided with a second annular protrusion; during the rest and movement of the inner bushing relative to the outer sleeve, the second annular protrusion remains in contact with the inner or outer wall surface of the outer sleeve. Through the above limitations, the first annular protrusion can shield the upper part of the elastomer; and / or, the second annular protrusion can shield the lower part of the elastomer, thereby reducing the risk of the upper and / or lower parts of the elastomer aging and failing due to exposure to rainwater and dust.

[0018] 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 another of the outer sleeve and inner bushing of the battery device is connected to the mounting beam.

[0019] By installing the aforementioned battery device in a vehicle, the top surface of the elastomer has a first annular groove; and / or the bottom surface of the elastomer has a second annular groove, which enables the bonding force between the middle part of the elastomer and the middle part of the outer sleeve to be greater than the bonding force between the top surface of the elastomer and the top end of the outer sleeve; and / or enables the bonding force between the middle part of the elastomer and the middle part of the outer sleeve to be greater than the bonding force between the bottom surface of the elastomer and the bottom end of the outer sleeve, thereby reducing the risk of tearing of the top surface of the elastomer, thereby increasing the bonding force between the middle part of the elastomer and the middle part of the outer sleeve, and thus increasing the service life of the shock absorption and anti-torsion components, etc.

[0020] In some embodiments, the outer sleeve is connected to the mounting beam, and the inner bushing is connected to the first lug of the outer sleeve. With the above limitations, the battery device can be at least partially mounted below the mounting beam.

[0021] In some embodiments, the vehicle body includes two spaced-apart mounting beams, with a second mounting lug of the outer sleeve located below the mounting beams, thereby suspending the battery pack of the battery unit between the two mounting beams. Through this limitation, the two mounting beams clamp a portion of the battery pack, thereby improving the stability of the battery unit suspended on the vehicle body.

[0022] In some embodiments, the inner bushing is connected to the first lug via a first bolt. The top end of the first bolt is located within a groove formed by the connection portion of the battery device, and the bottom end of the first bolt extends out of the inner bushing and connects to the first lug. This limitation not only achieves the connection between the shock-absorbing and torsional anti-parallel components and the battery housing, but also simplifies the structure and facilitates installation and operation. Furthermore, it reduces the probability of the top of the first bolt directly colliding with the mounting beam, thereby reducing the risk of damage to the mounting beam; it also reduces the risk of damage to the first bolt itself.

[0023] In some implementations, the distance between the first limiting component of the battery device and the mounting beam is greater than 5 mm. By limiting the distance, not only can the probability of the first limiting component directly colliding with the mounting beam be reduced, thereby reducing the risk of damage to the mounting beam; it can also reduce the risk of damage to the first limiting component, thereby improving the service life of the shock absorption and anti-torsion components.

[0024] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a shock-absorbing and anti-torsion component, including: an outer sleeve; an elastomer disposed inside the outer sleeve; the elastomer having a through hole; the top surface of the elastomer having a first annular groove, and / or the bottom surface of the elastomer having a second annular groove; an inner bushing disposed inside the through hole, and one of the outer sleeve and the inner bushing being connected to a first lug of the battery box.

[0025] By implementing the above limitations, the bonding force between the middle part of the elastomer and the middle part of the outer sleeve can be made greater than the bonding force between the top surface of the elastomer and the top end of the outer sleeve; and / or, the bonding force between the middle part of the elastomer and the middle part of the outer sleeve can be made greater than the bonding force between the bottom surface of the elastomer and the bottom end of the outer sleeve, thereby reducing the risk of tearing of the top surface of the elastomer, thereby increasing the bonding force between the middle part of the elastomer and the middle part of the outer sleeve, and thus increasing the service life of the shock absorption and anti-torsion component, etc.

[0026] In some embodiments, the damping and anti-torsion assembly includes a limiting component connected to the inner bushing. The limiting component is configured such that when the inner bushing moves axially a predetermined distance relative to the outer sleeve, the limiting component abuts against the outer sleeve to restrict the movement of the inner bushing relative to the outer sleeve. This limitation enables axial positioning of the elastomer, thereby reducing the risk of tensile damage to the elastomer and improving the service life of the damping and anti-torsion assembly.

[0027] In some embodiments, the limiting component includes a first limiting component connected to the top end of the inner bushing; when the inner bushing moves a predetermined distance relative to the outer sleeve towards the bottom end of the outer sleeve, the first limiting component abuts against the top end of the outer sleeve to restrict the axial movement of the inner bushing; and / or the limiting component includes a second limiting component connected to the bottom end of the inner bushing; when the inner bushing moves a predetermined distance relative to the outer sleeve towards the top end of the outer sleeve, the second limiting component abuts against the bottom end of the outer sleeve to restrict the axial movement of the inner bushing. Through the above limitations, axial limiting of the top and / or bottom of the elastomer can be achieved, thereby reducing the risk of tensile damage to the elastomer and improving the service life of the shock-absorbing and torsional-resistant component.

[0028] 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.

[0056] 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 connects the top wall and the bottom wall 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.

[0057] 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 hooks 110 is less than the number of shock-absorbing and anti-torsion assemblies 30, multiple shock-absorbing and anti-torsion assemblies 30 can be provided on the first hooks 110; or, the number of first hooks 110 and the number of shock-absorbing and anti-torsion assemblies 30 can be connected in a one-to-one correspondence, which is not limited here.

[0058] The outer sleeve 31 may be cylindrical. The outer sleeve 31 may be made of a rigid material. The rigid material may be, but is not limited to, metal or alloy materials. The outer sleeve 31 provides an installation position for the elastomer 32.

[0059] The elastomer 32 has a through hole 321. The through hole 321 extends through the upper and lower ends of the elastomer 32. The through hole 321 provides installation space for the inner bushing 33. The elastomer 32 can be, but is not limited to, rubber, springs, nitrogen cylinders, air springs, and related composite structures. The rubber, springs, nitrogen cylinders, air springs, and related composite structures are conventional components and are not limited here. When the elastomer 32 is made of rubber, the rubber is vulcanized and fixed inside the outer sleeve 31. When the elastomer 32 is of other structures, the elastomer 32 needs to be fixed inside the outer sleeve 31, and the fixing method is not limited.

[0060] The inner bushing 33 can be a hollow tube. The inner bushing 33 can be made of a rigid material, including but not limited to metals and alloys. The inner bushing 33 is disposed within the through hole 321 of the elastomer 32. The inner bushing 33 can be fixed within the through hole 321. When the elastomer 32 is rubber, the rubber is vulcanized and fixed between the outer sleeve 31 and the inner bushing 33.

[0061] One of the outer sleeve 31 and the inner bushing 33 is connected to the first lug 110, thereby connecting the shock-absorbing and anti-torsion assembly 30 to the outer periphery of the battery housing 10. Specifically, the outer sleeve 31 of the shock-absorbing and anti-torsion assembly 30 is connected to the first lug 110. Alternatively, the inner bushing 33 of the shock-absorbing and anti-torsion assembly 30 is connected to the first lug 110. The above connection method can be, but is not limited to, detachable or fixed.

[0062] When the top surface of the elastomer 32 has a first annular groove 322, the bonding force between the middle part of the elastomer 32 and the middle part of the outer sleeve 31 is greater than the bonding force between the top of the elastomer 32 and the top of the outer sleeve 31.

[0063] Alternatively, the bottom surface of the elastomer 32 may have a second annular groove 323, such that the bonding force between the middle part of the elastomer 32 and the middle part of the outer sleeve 31 is greater than the bonding force between the bottom of the elastomer 32 and the bottom of the outer sleeve 31.

[0064] Alternatively, when the top surface of the elastic body 32 has a first annular groove 322 and the bottom surface of the elastic body 32 has a second annular groove 323, the bonding force between the middle part of the elastic body 32 and the middle part of the outer sleeve 31 is not only greater than the bonding force between the top of the elastic body 32 and the top of the outer sleeve 31, but also the bonding force between the middle part of the elastic body 32 and the middle part of the outer sleeve 31 is greater than the bonding force between the bottom of the elastic body 32 and the bottom of the outer sleeve 31.

[0065] The presence of a first annular groove 322 on the top surface of the elastomer 32, and / or a second annular groove 323 on the bottom surface of the elastomer 32, enables the bonding force between the middle part of the elastomer 32 and the middle part of the outer sleeve 31 to be greater than the bonding force between the top of the elastomer 32 and the top of the outer sleeve 31; and / or enables the bonding force between the middle part of the elastomer 32 and the middle part of the outer sleeve 31 to be greater than the bonding force between the bottom of the elastomer 32 and the bottom end of the outer sleeve 31, thereby reducing the risk of tearing of the elastomer 32 and increasing the bonding force between the middle part of the elastomer 32 and the middle part of the outer sleeve 31, thus improving the service life of the shock-absorbing and anti-torsion assembly 30.

The bottom of the inner bushing 33 protrudes from the bottom of the outer sleeve 31, wherein the bottom surface of the inner bushing 33 is lower than the bottom surface of the outer sleeve 31.

[0077] The above-mentioned limitations not only enhance the bonding strength between the internal bushing 33 and the elastomer 32, but also provide installation positions for subsequent limiting components and the first bolt 36.

[0101] By limiting the elastic body 32 as described above, not only is the top axial limit of the elastic body 32 achieved, and / or the bottom axial limit of the elastic body 32 achieved, but the risk of damage caused by direct collision between the first limiting part 3411 and the outer sleeve 31 is also reduced, and / or the risk of damage caused by direct collision between the second limiting part and the outer sleeve 31 is also reduced, as well as abnormal noises.

[0102] Continue reading Figures 1 to 9 In some embodiments, the first limiting component 34 includes a first limiting plate 341. The first limiting plate 341 includes a first limiting portion 3411. The first limiting portion 3411 is formed on the circumferential edge of the first limiting plate 341.

The connecting portion 3412 is detachably or fixedly connected to the top of the inner bushing 33, which is not limited here.

[0104] The above-mentioned limitations not only increase the contact area between the top of the first limiting buffer pad 342 and the top of the outer sleeve 31, but also allow the first limiting plate 341 to be installed on the top of the inner bushing 33, while also providing an installation position for the subsequent first bolt 36.

[0105] Similarly, in other embodiments, the second limiting buffer pad 352 can be an integral structure or a separate structure. When the second limiting buffer pad 352 is an integral structure, it is disposed on the end face of the second limiting plate 351 facing the outer sleeve 31.

[0113] The above limitations improve the stability of the first limiting plate 341 connected to the inner bushing 33; and also reduce the size of the shock-absorbing and anti-torsion assembly 30 in the first direction X.

[0118] The above-mentioned limitations not only allow the first limiting plate 341 to be connected to the top of the inner bushing 33, but also make the structure simple and easy to install and operate.

[0119] Please see Figure 10 , Figure 10 yes Figure 8 A magnified view of part D is shown. Combined with... Figures 1 to 9 In some embodiments, one of the surface of the second limiting plate 351 and the bottom of the inner bushing 33 has a second engaging portion 3512. The other of the surface of the second limiting plate 351 and the bottom of the inner bushing 33 has a second engaging groove (not shown in the figure). The second engaging portion 3512 and the second engaging groove engage.

[0120] In this embodiment, a second engaging portion 3512 is provided on the surface of the second limiting plate 351. The second engaging portion 3512 is integrally formed on the second limiting plate 351. A second engaging groove is provided at the bottom of the inner bushing 33.

[0123] The above-mentioned limitations not only allow the second limiting plate 351 to be connected to the bottom end of the inner bushing 33, but also make the structure simple and easy to install and operate.

[0124] In some embodiments, the limiting component includes a first limiting component 34. The outer sleeve 31 includes an annular sidewall 311 and two second lugs 312 disposed on the outer surface of the annular sidewall 311. The end of the second lug 312 away from the annular sidewall 311 forms a mounting portion 3121 with a mounting hole 3122. The mounting portion 3121 is higher than the first limiting component 34.

[0125] The annular sidewall 311 is cylindrical and is used to accommodate the elastic body 32. The second hook 312 is detachably or fixedly connected to the outer surface of the annular sidewall 311. In this embodiment, the second hook 312 is integrally formed on the outer surface of the annular sidewall 311. The two second hooks 312 can be symmetrically arranged on the outer surface of the annular sidewall 311, which can improve the stability of the shock-absorbing and anti-torsion assembly 30 installed on the outer periphery of the battery box 10. The number of mounting holes 3122 on each mounting part 3121 can be, but is not limited to, one, two, or more than three.

[0126] The outer sleeve 31 is connected to the first hook 110 or the mounting beam 1100, etc., through the mounting holes 3122 of the mounting parts 3121 in the two second hooks 312. The mounting part 3121 is higher in the first direction than the first limiting component 34 in the first direction, that is, the surface of the mounting part 3121 is higher than the top of the first limiting component 34.

[0127] The outer sleeve 31 is connected to the first hook 110 or the mounting beam 1100 through the mounting holes 3122 of the mounting portions 3121 in the two second hooks 312. This not only ensures that the second hooks 312 of the outer sleeve 31 are stably connected to the first hook 110 or the mounting beam 1100, but also results in a simple structure that is easy to install and operate. In addition, the mounting portions 3121 are higher than the first limiting component 34, which reduces the risk of the first limiting component 34 colliding with the first hook 110 or the mounting beam 1100, thereby improving the service life of the shock-absorbing and anti-torsion component 30.

Figure 12 As shown, the first annular protrusion 343 is disposed at the bottom edge of the first limiting buffer pad 342, wherein the first annular protrusion 343 is in contact with the inner sidewall of the outer sleeve 31.

[0131] The first annular protrusion 343 can be detachably or fixed to the first limiting plate 341 and / or the first limiting buffer pad 342. The first annular protrusion 343 can be integrally formed or separately formed. The first annular protrusion 343 is arranged in a ring shape. When the first annular protrusion 343 is in contact with the inner wall surface of the outer sleeve 31, the top of the elastic body 32 can be provided with a relevant avoidance structure (not shown in the figure) to reduce motion interference, etc. The first annular protrusion 343 can be made of a flexible material, such as a plastic part.

[0132] And / or, similarly, the aforementioned second annular protrusion 353 can be disposed on the second limiting plate 351 and / or the second limiting buffer pad 352 of the second limiting assembly 35. For example... Figure 11 As shown, the second annular protrusion 353 is disposed at the top edge of the second limiting plate 351, wherein the second annular protrusion 353 maintains contact with the outer side wall of the outer sleeve 31. Figure 12 As shown, the second annular protrusion 353 is disposed at the top edge of the second limiting buffer pad 352, wherein the second annular protrusion 353 is in contact with the inner sidewall of the outer sleeve 31.

[0133] The second annular protrusion 353 can be detachably or fixed to the second limiting plate 351 and / or the second limiting buffer pad 352. The second annular protrusion 353 can be integrally or separately configured. The second annular protrusion 353 is arranged in a ring shape. When the second annular protrusion 353 is in contact with the inner wall surface of the outer sleeve 31, the bottom of the elastic body 32 can be provided with a relevant avoidance structure (not shown in the figure) to reduce motion interference, etc. The second annular protrusion 353 can be made of a flexible material, such as a plastic part.

[0134] With the above-mentioned limitations, the first annular protrusion 343 can shield the upper part of the elastomer 32; and / or, the second annular protrusion 353 can shield the lower part of the elastomer 32, thereby reducing the risk of the upper and / or lower parts of the elastomer 32 aging and failing due to exposure to rainwater and dust.

[0135] In some embodiments, both the elastomer 32 and the inner bushing 33 are elliptical cylinders. That is, the transverse cross-sectional shape of the elastomer 32 and the inner bushing 33 can be elliptical. The outer sleeve 31, the first limiting plate 341, and the second limiting plate 351 can all be made of rigid materials to improve strength, etc.

[0136] Please see Figure 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.

[0137] 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.

[0138] 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.

[0139] Please see Figure 13 , Figure 13 This is a structural schematic diagram of a vehicle according to one or more embodiments. (In conjunction with...) Figures 1 to 12This 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.

[0140] The vehicle 1000 includes a body (not shown in the figure) and the aforementioned battery assembly 100. The body includes a mounting beam 1100. Another of the outer sleeve 31 and inner bushing 33 in the battery assembly 100 is connected to the mounting beam 1100 of the body.

[0141] 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 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.

[0142] By installing the aforementioned battery device 100 in the vehicle 1000, the top surface of the elastomer 32 has a first annular groove 322; and / or the bottom of the elastomer 32 has a second annular groove 323, which enables the bonding force between the middle part of the elastomer 32 and the middle part of the outer sleeve 31 to be greater than the bonding force between the top of the elastomer 32 and the top of the outer sleeve 31; and / or enables the bonding force between the middle part of the elastomer 32 and the middle part of the outer sleeve 31 to be greater than the bonding force between the bottom of the elastomer 32 and the bottom end of the outer sleeve 31, thereby reducing the risk of tearing of the elastomer 32, thereby increasing the bonding force between the middle part of the elastomer 32 and the middle part of the outer sleeve 31, and thus increasing the service life of the shock-absorbing and anti-torsion assembly 30, etc.

[0143] The first lug 110 can be connected to the outer sleeve 31 or the inner bushing 33. The mounting beam 1100 can be connected to the inner bushing 33 or the outer sleeve 31. The positions of the first lug 110 and the mounting beam 1100 on the outer sleeve 31 and the inner bushing 33 can be determined according to the actual situation and are not limited here.

[0144] In some embodiments, the outer sleeve 31 of the shock-absorbing and torsion-resistant assembly 30 is connected to the vehicle body's mounting beam 1100. The inner bushing 33 of the shock-absorbing and torsion-resistant assembly 30 is connected to the first lug 110 of the battery box 10.

[0145] The outer sleeve 31 is detachably connected to the mounting beam 1100. For example, the outer sleeve is connected to the mounting beam 1100 by a second bolt. Specifically, the second bolt passes through the mounting hole 3122 of the mounting portion 3121 on the second lug 312 and is connected to the mounting beam.

[0146] The inner bushing 33 is detachably connected to the first hanging lug 110. For example, the inner bushing 33 is connected to the first hanging lug 110 via a first bolt 36. Specifically, the first bolt 36 passes sequentially through the second connecting hole 34121 of the connecting portion 3412 in the first limiting plate 341, the first connecting hole 331 of the inner bushing 33, and the third connecting hole 3511 of the second limiting plate 351, and connects to the first hanging lug 110. The number of the second bolt and the first bolt 36 can be determined according to actual conditions and is not limited here.

[0147] With the above limitations, the battery device 100 can be at least partially mounted below the mounting beam 1100.

[0148] In other embodiments, the outer sleeve 31 of the shock-absorbing and torsion-resistant assembly 30 is connected to the first lug 110 of the battery box 10. The inner bushing 33 of the shock-absorbing and torsion-resistant assembly 30 is connected to the vehicle body's mounting beam 1100.

[0149] The outer sleeve 31 is detachably connected to the first lug 110. For example, the outer sleeve 31 is connected to the first lug 110 by a second bolt. The inner bushing 33 is detachably connected to the mounting beam 1100. For example, the inner bushing 33 is connected to the mounting beam 1100 by a first bolt 36.

[0150] With the above limitations, the battery device 100 is at least partially supported above the mounting beam 1100.

[0151] In some embodiments, the vehicle body includes two spaced-apart mounting beams 1100. A second lug 312 of the outer sleeve 31 is disposed below the mounting beams 1100, thereby suspending the battery box 10 of the battery device 100 between the two mounting beams 1100.

[0152] The two mounting beams 1100 can be set along the length or width of the battery box 10.

[0153] With the above-mentioned constraints, the two mounting beams 1100 clamp part of the battery box 10, thereby improving the stability of the battery device 100 suspended on the vehicle body.

[0154] In some embodiments, the inner bushing 33 is connected to the first lug 110 by a first bolt 36. The top end of the first bolt 36 is located within a groove formed by the connection portion 3412 of the battery device 100. The bottom end of the first bolt 36 extends out of the inner bushing 33 and is connected to the first lug 110.

[0155] The tip of the first bolt 36 is lower than the tip of the connecting portion 3412. The groove provides a receiving position for the tip of the first bolt 36.

[0156] By implementing the above limitations, not only is the connection between the shock-absorbing and anti-torsion component 30 and the battery box 10 achieved, but the structure is also simple and easy to install and operate. At the same time, the probability of the top of the first bolt 36 directly colliding with the mounting beam 1100 is reduced, thereby reducing the risk of damage to the mounting beam 1100. In addition, the risk of damage to the first bolt 36 is also reduced.

[0157] In some embodiments, the distance between the first limiting component 34 of the battery device 100 and the mounting beam 1100 is greater than 5 mm.

[0158] The aforementioned spacing can be the length in the first direction X. Specifically, the spacing between the first limiting component 34 and the mounting beam 1100 can be, but is not limited to, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm.

[0159] By limiting the spacing, not only can the probability of the first limiting component 34 directly colliding with the mounting beam 1100 be reduced, thereby reducing the risk of damage to the mounting beam 1100; it can also reduce the risk of damage to the first limiting component 34, thereby improving the service life of the shock absorption and anti-torsion component 30.

[0160] In some embodiments, when the outer sleeve 31 is connected to the mounting beam 1100 and the inner bushing 33 is connected to the first lug 110, the mounting beam 1100 may be provided with mounting holes (not shown in the figure). The outer sleeve 31 has two second lugs 312. Each second lug 312 is provided with a mounting hole 3122. The number and position of the mounting holes correspond to the number and position of the mounting holes 3122. Second bolts (not shown in the figure) sequentially connect the mounting holes and the mounting holes 3122 to allow the battery device 100 to be mounted on the mounting beam 1100.

[0161] Please see Figure 14 , Figure 14 yes Figure 1 A magnified view of part B shown. Combined with... Figures 1 to 13In some embodiments, the mounting beam 1100 is provided with at least two mounting portions 1101. The mounting portions 1101 are detachable or fixed to the side of the mounting beam 1100. When a portion of the mounting beam 1100 is far from the shock-absorbing and torsion-resistant assembly 30 on the battery box 10, the mounting beam 1100 and the shock-absorbing and torsion-resistant assembly 30 can be connected via the mounting portions 1101 to meet different mounting beam 1100 shape requirements. One end of the mounting portion 1101 is connected to the mounting beam 1100, and the other end of the mounting portion 1101 is connected to the second lug 312 of the shock-absorbing and torsion-resistant assembly 30.
