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 improving battery lifespan. However, existing shock-absorbing components are prone to aging and failure due to internal structural aging, which further reduces 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 aging 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 hook on its outer periphery; a battery cell disposed in the battery housing; a shock-absorbing and anti-torsion assembly, including: an outer sleeve with an annular sidewall and a bottom wall; the annular sidewall and the bottom wall forming a receiving groove; the bottom wall having an opening; an elastic body disposed in the receiving groove and having an opening communicating with the opening; the bottom surface of the elastic body being exposed through the opening; an inner bushing disposed in the opening; the bottom end of the inner bushing being at least partially disposed in the opening, and one of the outer sleeve and the inner bushing being connected to the first hook; wherein, the outer surface of the bottom end of the inner bushing has a first flange; the first flange being at least partially located in the opening.

[0005] By having the first flange of the inner bushing located at least partially within the opening of the outer sleeve, the bottom surface of the elastomer can be shielded, reducing the risk of the elastomer aging and failing due to exposure to the outside and immersion in rainwater, thereby improving the service life of the shock-absorbing and anti-torsion components.

[0006] In some embodiments, the first flange is fitted and fixedly connected to the exposed bottom surface of the elastomer. This limitation not only improves the bonding force between the inner bushing and the elastomer but also better shields the exposed bottom surface of the elastomer, thereby reducing the risk of aging and failure due to rainwater immersion.

[0007] In some embodiments, the thickness of the first flange is the same as the thickness of the bottom wall of the outer sleeve; the entire first flange is located within the opening. With the above-described limitation, the bottom of the first flange is flush with the bottom wall of the outer sleeve, making it easier for the first lug or mounting beam to be positioned by the outer sleeve.

[0008] In some embodiments, the first flange is annular, and the opening is circular; the outer diameter of the first flange is 90%-95% of the aperture of the opening. By limiting the outer diameter of the first flange to the range of the aperture of the opening, not only can the area of ​​the exposed bottom surface of the elastomer covered by the first flange be increased, thereby further reducing the risk of the elastomer aging and failing due to exposure to rainwater, etc.; it can also reduce the risk of blockage during the movement of the first flange relative to the opening, thereby facilitating the relative movement of the elastomer between the outer sleeve and the inner bushing.

[0009] In some embodiments, the thickness of the first flange is greater than the thickness of the bottom wall of the outer sleeve; wherein, along the thickness direction of the first flange, a portion of the first flange protrudes beyond the opening and extends into the receiving groove; and / or, a portion of the first flange protrudes beyond the opening and extends outside the receiving groove. Through the above limitations, it is ensured that during the vibration of the inner bushing, the first flange remains partially at the opening and will not dislodge, thereby always shielding the exposed bottom surface of the elastomer, thus reducing the risk of the elastomer aging and failing due to exposure to rainwater, etc.

[0010] In some embodiments, the exposed bottom surface of the elastomer has a relief groove; a portion of the first flange is embedded in the relief groove. The relief groove can be used to embed the first flange and increase the contact area with the first flange, etc.; at the same time, it can also reduce the risk of motion interference between the elastomer and the inner bushing, etc.

[0011] In some implementations, there are multiple openings, perforations, and internal bushings, each corresponding to the other. By limiting these quantities, the shock absorption and torsional resistance effects can be improved.

[0012] In some embodiments, the top surface of the elastomer and the top of the inner bushing are both lower than the opening of the receiving groove. By defining the positional relationship between the elastomer and the inner bushing relative to the receiving groove, it is possible not only to reduce the probability of the top surface of the elastomer and the top of the inner bushing directly colliding with the first mounting lug or the mounting beam on the vehicle body, thereby reducing the risk of damage to the first mounting lug or the mounting beam on the vehicle body; but also to reduce the risk of damage to the elastomer and the inner bushing, thereby improving the service life of the shock absorption and anti-torsion components.

[0013] In some embodiments, the distance between the top surface of the elastomer and the opening of the receiving groove is greater than or equal to 5 mm and less than or equal to 10 mm; and / or the distance between the top of the inner bushing and the opening of the receiving groove is greater than or equal to 5 mm and less than or equal to 10 mm. By limiting the above distances, not only is the risk of damage to the first mounting lug or the mounting beam on the vehicle body further reduced; but the risk of damage to the elastomer and the inner bushing is also reduced; at the same time, the size of the shock-absorbing and anti-torsion assembly can also be reduced.

[0014] In some embodiments, the outer surface of the top end of the inner bushing has a second flange, which is fitted and fixedly connected to the top surface of the elastomer. This limitation not only enhances the bonding force between the elastomer and the inner bushing but also improves the stability of the inner bushing when mounted on the elastomer.

[0015] In some embodiments, the outer diameter of the second flange is larger than the aperture of the opening. By defining the relationship between the outer diameter of the second flange and the aperture of the opening, the orthographic projection of the second flange onto the bottom wall of the outer sleeve at least partially overlaps with the bottom wall. The second flange exerts a certain compressive force on the elastomer and the bottom wall, thereby improving the shock absorption and torsional resistance effects.

[0016] In some embodiments, the top of the annular sidewall of the outer sleeve has two outwardly extending second lugs, each lug having a mounting hole. By defining the second lugs, the ease of mounting the outer sleeve to the first lug or the mounting beam can be improved.

[0017] In some embodiments, the top surface of the second lug is flush with the top end face of the annular sidewall of the outer sleeve. When the second lug is installed on the first lug or the mounting beam, the first lug or the mounting beam can at least cover the opening of the receiving groove, thereby preventing at least part of the rainwater from entering the receiving groove, thus reducing the risk of the elastomer aging and failing due to exposure to rainwater immersion; at the same time, the top surface of the second lug and the annular sidewall of the outer sleeve can also play a certain supporting role, thereby improving the support stability, etc.

[0018] In some embodiments, the second lug connects to the top of the annular sidewall of the outer sleeve to form a corner, and the outer angle of the corner is arc-shaped. By defining the corner as arc-shaped, it is convenient for the elastomer to be installed in the receiving groove of the outer sleeve.

[0019] In some embodiments, both the receiving groove and the elastomer are frustum-shaped, with the diameter of the frustum gradually decreasing along the direction from the opening of the receiving groove to the bottom wall. Through the above-described constraints, the annular sidewall of the outer sleeve can provide a certain supporting force to the elastomer, further enhancing the bonding force between the elastomer and the outer sleeve, thereby reducing the risk of damage to the elastomer and thus extending the service life of the shock-absorbing and torsional-resistant assembly.

[0020] 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.

[0021] By having the first flange of the inner bushing located at least partially within the opening of the outer sleeve, the bottom surface of the elastomer can be shielded, reducing the risk of the elastomer aging and failing due to exposure to the outside and immersion in rainwater, thereby improving the service life of the shock-absorbing and anti-torsion components.

[0022] In some embodiments, the outer sleeve is connected to the mounting beam, and the inner bushing is connected to the first mounting lug of the battery device. With the above limitations, the battery device can be at least partially mounted below the mounting beam.

[0023] 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. This limitation improves the stability of the battery unit suspended on the vehicle body.

[0024] In some embodiments, the inner bushing is connected to the first lug via a first bolt. The tip of the first bolt is located within the receiving groove of the outer sleeve, and the bottom end of the first bolt extends from the opening of the outer sleeve out of the receiving groove and connects to the first lug; wherein the tip of the first bolt is lower than the opening of the receiving groove. Through the above limitations, not only is the connection between the shock-absorbing and torsional anti-vibration components and the battery box achieved, but the structure is also simple and easy to install and operate; at the same time, the probability of the tip of the first bolt directly colliding with the mounting beam is reduced, thereby reducing the risk of damage to the mounting beam; additionally, the risk of damage to the first bolt is also reduced.

[0025] In some implementations, the distance between the top of the first bolt and the mounting beam is greater than 5 mm. By limiting the distance, not only can the probability of the top of the first bolt directly colliding with the mounting beam be reduced, thereby reducing the risk of damage to the mounting beam, but the risk of damage to the first bolt can also be reduced, thus improving the service life of the shock absorption and anti-torsion components.

[0026] To solve the above-mentioned technical problems, one technical solution adopted in this application is: providing a shock-absorbing and torsional anti-vibration component, comprising: an outer sleeve, including an annular sidewall and a bottom wall; the annular sidewall and the bottom wall surround to form a receiving groove; the bottom wall has an opening; an elastic body, disposed in the receiving groove, having an opening communicating with the opening; the bottom surface of the elastic body is exposed through the opening; an inner bushing, disposed in the opening; the bottom end of the inner bushing is at least disposed in the opening; wherein, the outer surface of the bottom end of the inner bushing has a first flange; the first flange is at least partially located in the opening.

[0027] By placing at least a portion of the first flange of the inner bushing within the opening of the outer sleeve, the bottom surface of the elastomer can be shielded, reducing the risk of the elastomer aging and failing due to exposure to the outside and immersion in rainwater, thereby improving the service life of the shock-absorbing and anti-torsion assembly.

[0028] In some embodiments, the thickness of the first flange is the same as the thickness of the bottom wall of the outer sleeve; the entire first flange is located within the opening. This limitation not only further enhances the bonding force between the inner bushing and the elastomer, but also shields the exposed bottom surface of the elastomer, thereby reducing the risk of aging and failure due to rainwater immersion.

[0029] In some embodiments, the top surface of the elastomer and the top of the inner bushing are both lower than the opening of the receiving groove. By defining the positional relationship between the elastomer and the inner bushing relative to the receiving groove, it is possible not only to reduce the probability of the top surface of the elastomer and the top of the inner bushing directly colliding with the first mounting lug or the mounting beam on the vehicle body, thereby reducing the risk of damage to the first mounting lug or the mounting beam on the vehicle body; but also to reduce the risk of damage to the elastomer and the inner bushing, thereby improving the service life of the shock absorption and anti-torsion components.

[0030] In some embodiments, the top of the annular sidewall of the outer sleeve has two outwardly extending second lugs, the top surface of which is flush with the end face of the top of the annular sidewall of the outer sleeve. When the second lugs are installed on the first lug or the mounting beam, the first lug or the mounting beam can at least cover the opening of the receiving groove, thereby preventing at least part of the rainwater from entering the receiving groove, thus reducing the risk of the elastomer aging and failing due to exposure to rainwater immersion; at the same time, the top surface of the second lugs and the annular sidewall of the outer sleeve can also play a certain supporting role, thereby improving the support stability, etc.

[0054] Existing battery devices are flexibly connected to vehicles using shock-absorbing components, which reduces vibrations transmitted to the battery device during vehicle operation, thereby improving battery life. However, during use, the internal structure of existing shock-absorbing components is prone to aging and failure, thus reducing their lifespan. The inventors have discovered that this failure is due to the aging of the elastomer in the shock-absorbing component, caused by partial exposure to rainwater and other factors.

When the opening 321 is a through hole, the through hole and the opening 3121 are connected, and the through hole passes through the upper and lower ends of the elastomer 32. When the opening 321 is a blind hole, the bottom of the blind hole and the opening 3121 are connected, and the top of the blind hole does not pass through the upper end of the elastomer 32. When there are two or more openings 321, both or more openings 321 are through holes; or both or more openings 321 are blind holes; or one or more openings 321 are through holes; or one or more openings 321 are blind holes.

[0062] The elastomer 32 can be, but is not limited to, rubber, springs, nitrogen cylinders, air springs, and related composite structures. The aforementioned rubber, springs, nitrogen cylinders, air springs, and related composite structures are conventional components and are not limited here. When the elastomer 32 is rubber, the rubber is vulcanized and fixed within the receiving groove 313 and fixedly connected to the outer sleeve 31. When the elastomer 32 is of other structures, the elastomer 32 needs to be fixed within the receiving groove 313, and the fixing method is not limited.

[0065] Please see Figure 7 , Figure 8 , Figure 9 as well as Figure 10 , Figure 7 yes Figure 3 A magnified view of part B shown; Figure 8 This is a schematic diagram of a third partial section of a shock-absorbing and torsional-resistant assembly according to one or more embodiments; Figure 9 This is a schematic diagram of a fourth partial section of a shock-absorbing and torsional-resistant assembly according to one or more embodiments; Figure 10 This is a fifth partial cross-sectional schematic diagram of a shock-absorbing and torsional-resistant assembly according to one or more embodiments. (Combined with...) Figures 1 to 6 The first flange 331 is fixedly or detachably connected to the outer side of the bottom end of the inner bushing 33. In this embodiment, the first flange 331 is integrally formed on the outer side of the bottom end of the inner bushing 33. The upper part of the first flange 331 is located outside the opening 3121, and the lower part of the first flange 331 is located inside the opening 3121. Alternatively, the upper part of the first flange 331 is located inside the opening 3121, and the lower part of the first flange 331 is located outside the opening 3121, as shown below. Figure 8 Alternatively, both the upper and lower parts of the first flange 331 are located outside the opening 3121, such as... Figure 9 Alternatively, the entire first flange 331 may be disposed within the opening 3121, such as... Figure 10 .

[0066] When the elastomer 32 is in its natural state, the first flange 331 is at least partially located within the opening 3121. When the elastomer 32 is in a vibration-resistant torsional state, the first flange 331 is at least partially located within the opening 3121. That is, regardless of the state of the elastomer 32, the first flange 331 on the inner bushing 33 is always at least partially located within the opening 3121, which can cover the bottom surface of the elastomer 32.

[0067] By having the first flange 331 of the inner bushing 33 located at least partially within the opening 3121 of the outer sleeve 31, the bottom surface of the elastomer 32 can be shielded, reducing the risk of the elastomer 32 aging and failing due to exposure to the outside and being soaked by rainwater, thereby improving the service life of the shock-absorbing and anti-torsion assembly 30.

[0068] In some embodiments, the first flange 331 is attached to and fixedly connected to the exposed bottom surface of the elastomer 32.

[0069] The exposed bottom surface of the elastomer 32 refers to the portion of the bottom surface of the elastomer 32 exposed through the opening 3121. The top surface of the first flange 331 and the exposed bottom surface of the elastomer 32 are disposed adjacent to each other. The fixing method may be, but is not limited to, vulcanization fixing.

[0070] The above-mentioned limitations not only enhance the bonding force between the inner bushing 33 and the elastomer 32, but also better shield the exposed bottom surface of the elastomer 32, thereby reducing the risk of the elastomer 32 aging and failing due to exposure to rainwater.

[0071] The thickness of the first flange 331 can be the same as or different from the thickness of the bottom wall 312 of the outer sleeve 31. The thickness of the first flange 331 can be the length in the first direction X, such as... Figure 7 As shown.

[0072] Please see Figure 11 , Figure 11 This is a schematic diagram of a sixth partial cross-section of a shock-absorbing and torsional-resistant assembly according to one or more embodiments. (In conjunction with...) Figures 1 to 10 In some embodiments, the thickness of the first flange 331 is the same as the thickness of the bottom wall 312 of the outer sleeve 31. The first flange 331 is entirely located within the opening 3121.

[0073] The top surface of the first flange 331 is flush with the surface of the bottom wall 312; the bottom surface of the first flange 331 is flush with the bottom surface of the bottom wall 312. When the first flange 331 is in contact with the exposed bottom surface of the elastomer 32, the unexposed bottom surface of the elastomer 32 is also in contact with the bottom surface of the bottom wall 312 of the outer sleeve 31.

[0074] With the above-mentioned limitations, the bottom of the first flange 331 is flush with the bottom wall of the outer sleeve 31, making it easier for the first lug 110 or the mounting beam 1100 to be limited by the outer sleeve 31.

[0075] In one specific embodiment, when the thickness of the first flange 331 is the same as the thickness of the bottom wall 312 of the outer sleeve 31, the bottom surface of the elastic body 32, the inner surface of the bottom wall 312, and the top surface of the first flange 331 are flush and fitted together, such as being horizontally arranged.

[0076] In other embodiments, the thickness of the first flange 331 is greater than the thickness of the bottom wall 312 of the outer sleeve 31. Specifically, along the thickness direction of the first flange 331, a portion of the first flange 331 protrudes from the opening 3121 and extends into the receiving groove 313.

[0077] That is, the top surface of the first flange 331 is higher than the inner surface of the bottom wall 312, such as Figure 9 And / or, a portion of the first flange 331 protrudes beyond the opening 3121 and extends beyond the receiving groove 313, as shown below. Figure 8 and Figure 9 That is, the bottom surface of the first flange 331 protrudes beyond the bottom surface of the bottom wall 312.

[0078] Through the above limitations, it is ensured that during the vibration of the internal bushing 33, the first flange 331 will always remain at the opening 3121 and will not come out, thereby always being able to cover the exposed bottom surface of the elastomer 32, thereby reducing the risk of the elastomer 32 aging and failing due to exposure to rainwater.

[0079] In one specific embodiment, when a portion of the first flange 331 protrudes from the opening 3121 and extends into the receiving groove 313 along the thickness direction of the first flange 331, the exposed bottom surface of the elastomer 32 has a relief groove 322; a portion of the first flange 331 is embedded in the relief groove 322.

[0080] like Figure 9 The aforementioned clearance groove 322 can be used to embed the first flange 331 and increase the contact area with the first flange 331; at the same time, it can also reduce the risk of motion interference between the elastomer 32 and the inner bushing 33.

[0081] In some other embodiments, the thickness of the first flange 331 is less than the thickness of the bottom wall 312 of the outer sleeve 31, such as... Figure 10 Along the thickness direction of the first flange 331, the bottom surface of the first flange 331 is located inside the opening 3121, wherein the first flange 331 is sufficient to cover the exposed bottom surface of the elastomer 32.

[0082] In some embodiments, the first flange 331 is annular. The opening 3121 is circular. The outer diameter of the first flange 331 is 90%-95% of the diameter of the opening 3121.

[0083] The aperture can be a diameter. Specifically, the outer diameter of the first flange 331 can be, but is not limited to, 90%, 90.5%, 91%, 91.5%, 92%, 92.5%, 93%, 93.5%, 94%, 94.5%, and 95% of the aperture of the opening 3121, etc., and is not limited here.

[0084] By limiting the outer diameter of the first flange 331 within the aperture range of the opening 3121, not only can the area of ​​the exposed bottom surface of the elastomer 32 covered by the first flange 331 be increased, thereby further reducing the risk of the elastomer 32 aging and failing due to exposure to rainwater, etc.; it can also reduce the risk of the first flange 331 being blocked during its movement relative to the opening 3121, thereby facilitating the relative movement between the outer sleeve 31 and the inner bushing 33 through the elastomer 32, etc.

[0085] In some embodiments, there are multiple openings 3121, holes 321, and inner bushings 33. Furthermore, the number of openings 3121, holes 321, and inner bushings 33 are all configured in a one-to-one correspondence.

[0086] The number of openings 3121, holes 321, and inner bushings 33 can be, but is not limited to, one, two, or more than three. An inner bushing 33 is disposed inside each hole 321, and the first flange 331 of each inner bushing 33 is located on an opening 3121, achieving a one-to-one correspondence. In this embodiment, the number of openings 3121, holes 321, and inner bushings 33 are all two. Furthermore, the two openings 3121 are symmetrically arranged on the bottom wall 312 of the outer sleeve 31.

[0087] By limiting the aforementioned quantities, the shock absorption and torsional resistance effects can be improved.

[0088] In some embodiments, the top surface of the elastomer 32 and the top of the inner bushing 33 are both lower than the opening 3131 of the receiving groove 313.

[0089] The opening 3131 of the receiving groove 313 can be located at the top of the annular sidewall 311. When the battery device 100 vibrates, the movement of the top surface of the elastomer 32 and the top of the inner bushing 33 is confined within the receiving groove 313.

[0090] By limiting the positional relationship between the elastomer 32 and the inner bushing 33 relative to the receiving groove 313, it is possible not only to reduce the probability of the top surface of the elastomer 32 and the top of the inner bushing 33 directly colliding with the first hanger 110 or the mounting beam 1100 on the vehicle body, thereby reducing the risk of damage to the first hanger 110 or the mounting beam 1100 on the vehicle body; but also to reduce the risk of damage to the elastomer 32 and the inner bushing 33, thereby improving the service life of the shock absorption and anti-torsion assembly 30.

[0091] In one specific embodiment, the distance between the top surface of the elastomer 32 and the opening 3131 of the receiving groove 313 is greater than or equal to 5 mm and less than or equal to 10 mm. And / or, the distance between the top end of the inner bushing 33 and the opening 3131 of the receiving groove 313 is greater than or equal to 5 mm and less than or equal to 10 mm.

[0092] Wherein, distance refers to length along the first direction X. Specifically, the distance between the top surface of the elastic body 32 and the opening 3131 of the receiving groove 313 can be, but is not limited to, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm. And / or, the distance between the top end of the inner bushing 33 and the opening 3131 of the receiving groove 313 can be, but is not limited to, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm.

[0093] By limiting the distance as described above, the risk of damage to the first lug 110 or the mounting beam 1100 on the vehicle body is further reduced; the risk of damage to the elastomer 32 and the internal bushing 33 is also reduced; and the size of the shock absorption and anti-torsion assembly 30 is also reduced.

[0094] The distance between the top surface of the elastic body 32 and the opening 3131 of the receiving groove 313 can be greater than or equal to the distance between the top of the inner bushing 33 and the opening 3131 of the receiving groove 313. In this embodiment, the distance between the top surface of the elastic body 32 and the opening 3131 of the receiving groove 313 can be greater than the distance between the top of the inner bushing 33 and the opening 3131 of the receiving groove 313.

[0095] In some embodiments, the outer surface of the top end of the inner bushing 33 has a second flange 332. The second flange 332 is attached to and fixedly connected to the top surface of the elastomer 32.

[0096] When the inner bushing 33 has the aforementioned second flange 332, the opening 321 is a through hole. The inner bushing 33 is connected to the upper and lower ends of the elastic body 32 through the through hole. The aforementioned second flange 332 is detachably or fixedly connected to the outer surface of the top end of the inner bushing 33. In this embodiment, the second flange 332 is integrally formed on the outer surface of the top end of the inner bushing 33. The aforementioned second flange 332 and first flange 331 are arranged vertically opposite each other. The outer diameter of the second flange 332 and the outer diameter of the first flange 331 can be the same or different. In this embodiment, for example, the outer diameter of the second flange 332 is smaller than the outer diameter of the first flange 331, etc.

[0097] The above limitations not only enhance the bonding force between the elastomer 32 and the inner bushing 33, but also improve the stability of the inner bushing 33 when installed on the elastomer 32.

[0098] In some embodiments, the outer diameter of the second flange 332 is larger than the aperture of the opening 3121.

[0099] The outer diameter of the second flange 332 refers to the length extending outward along the outer side wall of the inner bushing. By defining the relationship between the outer diameter of the second flange 332 and the aperture of the opening 3121, the orthographic projection of the second flange 332 onto the bottom wall 312 of the outer sleeve 31 at least partially overlaps with the bottom wall 312. The second flange 332 exerts a certain compressive force on the elastomer 32 and the bottom wall 312, thereby improving the shock absorption and torsional resistance effects.

[0100] In some embodiments, the top end of the annular sidewall 311 of the outer sleeve 31 has two outwardly extending second lugs 314. The second lugs 314 have mounting holes 3141.

[0101] The second lug 314 can be installed on the first lug 110 or the mounting beam 1100 through the mounting hole 3141. The second lug 314 can be detached or fixed to the outer periphery of the top end of the outer sleeve 31. In this embodiment, the second lug 314 is integrally formed on the outer sleeve 31. The two second lugs 314 can be symmetrically arranged on the top end of the annular sidewall 311 of the outer sleeve 31, which can improve the force balance on both sides of the shock-absorbing and anti-torsion component 30. The number of mounting holes 3141 on each second lug 314 can be, but is not limited to, one, two, or more than three. In addition, the number of openings 3121, holes 321, and inner bushings 33 are all two, and the two second lugs 314, two openings 3121, two holes 321, and two inner bushings 33 are all located on the same center line.

[0102] By limiting the second lug 314, the convenience of installing the outer sleeve 31 on the first lug 110 or the mounting beam 1100 can be improved, thereby improving installation efficiency.

[0103] In some embodiments, the top surface of the second lug 314 is flush with the end face of the top of the annular sidewall 311 of the outer sleeve 31.

[0104] Here, "flush" means that the top surface of the second lug 314 and the top surface of the top of the annular sidewall 311 are on the same horizontal plane. When the second lug 314 is installed on the first lug 110 or the mounting beam 1100, the first lug 110 or the mounting beam 1100 can at least cover the opening 3131 of the receiving groove 313, thereby preventing at least part of the rainwater from entering the receiving groove 313, thus reducing the risk of the elastomer 32 aging and failing due to exposure to rainwater immersion; at the same time, the top surface of the second lug 314 and the annular sidewall 311 of the outer sleeve 31 can also play a certain supporting role, thereby improving the support stability, etc.

[0105] In some embodiments, the second lug 314 is connected to the top end of the annular sidewall 311 of the outer sleeve 31 to form a corner (not shown in the figure). The outer corner of the corner is arc-shaped.

[0106] By defining the corners as arc-shaped, it is easier for the elastomer 32 to be installed in the receiving groove 313 of the outer sleeve 31.

[0107] In some embodiments, both the receiving groove 313 and the elastic body 32 are frustum-shaped. The diameter of the frustum gradually decreases along the direction from the opening 3131 of the receiving groove 313 to the bottom wall 312.

[0108] With the above limitations, the annular sidewall 311 of the outer sleeve 31 can provide a certain support force for the elastomer 32, further enhance the bonding force between the elastomer 32 and the outer sleeve 31, thereby reducing the risk of damage to the elastomer 32 and thus improving the service life of the shock absorption and anti-torsion assembly 30.

[0109] Specifically, the outer sleeve 31 can also be frustoconical. The outer sleeve 31 matches the shape of the receiving groove 313 and the elastomer 32, further enhancing the bonding force between the elastomer 32 and the outer sleeve 31, thereby reducing the risk of damage to the elastomer 32. In other embodiments, the outer sleeve 31 can also be frustoelliptical. Furthermore, both the outer sleeve 31 and the inner bushing 33 can be made of rigid materials, which can improve the rigidity of the outer sleeve 31 and the inner bushing 33.

[0110] Please see Figure 6 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.

[0111] 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.

[0112] 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.

[0113] Please see Figure 12 , Figure 12 This is a structural schematic diagram of a vehicle according to one or more embodiments. (In conjunction with...) Figures 1 to 11 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.

[0114] Vehicle 1000 includes a body (not shown in the figure) and the aforementioned battery device 100. The body includes a mounting beam 1100. Another of the outer sleeve 31 and inner bushing 33 in the battery device 100 is connected to the mounting beam 1100 of the body so that the battery device 100 is connected to the body via a shock-absorbing and anti-torsion assembly 30.

[0115] 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.

[0116] By installing the battery device 100 in the vehicle 1000, the first flange 331 of the inner bushing 33 is at least partially located in the opening 3121 of the outer sleeve 31, which can cover the bottom part of the elastomer 32, reduce the risk of the elastomer 32 aging and failing due to exposure to the outside and being soaked by rainwater, thereby improving the service life of the shock absorption and anti-torsion assembly 30.

[0117] 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.

[0118] 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.

[0119] The outer sleeve 31 is detachably connected to the mounting beam 1100. For example, the outer sleeve is bolted to the mounting beam 1100 via a second bolt. The inner bushing 33 is detachably connected to the first lug 110. For example, the inner bushing 33 is bolted to the first lug 110 via a first bolt 34.

[0120] With the above limitations, the battery device 100 can be at least partially mounted below the mounting beam 1100.

[0121] 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.

[0122] The outer sleeve 31 is detachably connected to the first lug 110. The inner bushing 33 is detachably connected to the mounting beam 1100.

[0123] With the above limitations, the battery device 100 is at least partially supported above the mounting beam 1100.

[0124] In some embodiments, the vehicle body includes two spaced-apart mounting beams 1100. A second lug 314 of the outer sleeve 31 is disposed below the mounting beams 1100, thereby suspending the battery box 10 between the two mounting beams 1100.

[0125] The two mounting beams 1100 can be set along the length or width of the battery box 10.

[0126] 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.

[0127] In some embodiments, the inner bushing 33 is connected to the first lug 110 by a first bolt 34. The top end of the first bolt 34 is located within the receiving groove 313. The bottom end of the first bolt 34 extends out of the receiving groove 313 from the opening 3121 and is connected to the first lug 110.

[0128] The inner bushing 33 is connected to the first lug 110 via the first bolt 34, thereby connecting the shock-absorbing and anti-torsion assembly 30 and the battery box 10. The top of the first bolt 34 is lower than the opening 3131 of the receiving groove 313.

[0129] 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 34 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 34 is also reduced.

[0130] In some embodiments, the distance between the top of the first bolt 34 and the mounting beam 1100 is greater than 5 mm.

[0131] The aforementioned spacing can be the length in the first direction X. Specifically, the spacing between the top of the first bolt 34 and the mounting beam 1100 can be, but is not limited to, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm.

[0132] By limiting the spacing, not only can the probability of the top of the first bolt 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 bolt 34, thereby improving the service life of the shock absorption and anti-torsion assembly 30.

[0133] A receiving groove 313 extends from the opening 3121 at the bottom end of the first bolt 34 and connects to the first lug 110. A washer 35 is fitted on the first bolt 34. The washer 35 is located between the bottom of the inner bushing 33 and the first nut (not shown in the figure) to further reduce vibration transmission, etc.

[0134] Please see Figure 13 , Figure 13 yes Figure 1 A magnified view of a portion of point A is shown. (Combined with...) Figures 1 to 12 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 hanging lug 110, the mounting beam 1100 may be provided with mounting holes 11001. The outer sleeve 31 has two second hanging lugs 314. Each second hanging lug 314 is provided with a mounting hole 3141. The number and position of the mounting holes 11001 correspond to the number and position of the mounting holes 3141. A second bolt sequentially connects the mounting holes 11001 and the mounting holes 3141, so that the battery device 100 can be mounted on the mounting beam 1100.

[0135] Review Figures 2 to 5 , Figures 6 to 11This application provides a shock-absorbing and torsional-resistant assembly. The shock-absorbing and torsional-resistant assembly 30 includes an outer sleeve 31, an elastomer 32, and an inner bushing 33. The outer sleeve 31 includes an annular sidewall 311 and a bottom wall 312. The annular sidewall 311 and the bottom wall 312 form a receiving groove 313. The bottom wall 312 has an opening 3121. The elastomer 32 is disposed in the receiving groove 313 and has an opening 321 communicating with the opening 3121. The bottom surface of the elastomer 32 is exposed through the opening 3121. The inner bushing 33 is disposed in the opening 321. The bottom end of the inner bushing 33 is at least disposed in the opening 3121. The outer surface of the bottom end of the inner bushing 33 has a first flange 331; the first flange 331 is at least partially located in the opening 3121.

[0136] In some embodiments, the first flange 331 is abutted and fixedly connected to the exposed bottom surface of the elastomer 32. The thickness of the first flange 331 is the same as the thickness of the bottom wall 312 of the outer sleeve 31; the entire first flange 331 is located within the opening 3121. The thickness of the first flange 331 is greater than the thickness of the bottom wall 312 of the outer sleeve 31; wherein, along the thickness direction of the first flange 331, a portion of the first flange 331 protrudes from the opening 3121 and extends into the receiving groove 313; and / or, a portion of the first flange 331 protrudes from the opening 3121 and extends outside the receiving groove 313. The exposed bottom surface of the elastomer 32 has a relief groove 322; a portion of the first flange 331 is embedded in the relief groove 322.

[0137] In some embodiments, the first flange 331 is annular and the opening 3121 is circular; the outer diameter of the first flange 331 is 90-95% of the diameter of the opening 3121. In some embodiments, there are multiple openings 3121, holes 321, and inner bushings 33, and they are arranged in a one-to-one correspondence.

[0138] In some embodiments, the top surface of the elastomer 32 and the top tip of the inner bushing 33 are both lower than the opening 3131 of the receiving groove 313. The distance between the top surface of the elastomer 32 and the opening 3131 of the receiving groove 313 is greater than or equal to 5 mm and less than or equal to 10 mm; and / or the distance between the top tip of the inner bushing 33 and the opening 3131 of the receiving groove 313 is greater than or equal to 5 mm and less than or equal to 10 mm.

[0139] In some embodiments, the outer surface of the top end of the inner bushing 33 has a second flange 332, which is attached to and fixedly connected to the top surface of the elastomer 32. The outer diameter of the second flange 332 is larger than the aperture of the opening 3121.

[0140] In some embodiments, the top end of the annular sidewall 311 of the outer sleeve 31 has two outwardly extending second lugs 314, each with a mounting hole 3141.
