Description

Technical Field

[0001] This utility model relates to the field of battery cells, specifically to a support base for battery cells. Background Technology

[0002] In the field of battery technology, cell support brackets, as key structural components of battery modules, are widely used in new energy vehicles, energy storage systems, and other scenarios. Their core function is to provide stable mechanical support for the cells, ensuring their positional stability and protection under complex operating conditions. Simultaneously, they must meet comprehensive performance requirements such as heat dissipation, insulation, and vibration resistance, making them an important branch of battery pack structure design and manufacturing technology. Furthermore, existing cells can be assembled using support brackets to form battery modules.

[0003] Existing battery cell support brackets typically employ a bracket-type structure, made of metal or composite materials, and assemble the battery cells to the housing using connection methods such as slots, snap-fits, or bolts. Specifically, the bracket body has positioning grooves or limiting structures to accommodate the battery cells and is fixedly connected to the housing. At the same time, multiple battery cells can be combined for use through external snap-fit ​​structures.

[0004] However, existing cell support technologies still have certain drawbacks. The direct connection between the bracket and the housing, and the simple plug-in assembly of the cell and bracket, allow external vibrations to be easily transmitted to the cell through the bracket, increasing the risk of axial movement. Traditional solutions require the addition of independent damping pads between the bracket and the housing, but the protection effect on the cell is still unsatisfactory, affecting the stability of cell installation. Furthermore, the existing brackets provide insufficient support and protection for the cell, making it susceptible to displacement under long-term slight movement, affecting the consistency and reliability of the cell. Therefore, a highly protective support is urgently needed to improve the stability and reliability of cell installation. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a support base for battery cells, so as to solve the technical problem in the background art of how to improve the support and protection effect of battery cells, thereby enhancing the stability and reliability of the support base.

[0006] The objective of this utility model is achieved through the following means:

[0007] A support base for a battery cell includes a base with a receiving cavity formed thereon. A mounting hole is formed at the top of the receiving cavity. A support portion for supporting the battery cell is formed at the bottom of the base. A support portion for positioning and support is provided in the middle of the support portion. A through hole is provided on the support portion. A protective portion is formed on the side of the base. At least two through-holes are provided on the protective portion. Protective bushings are nested in pairs on the inner wall of the receiving cavity. The outer side of the protective bushings is connected to the receiving cavity via a clamping structure. A through-hole is provided inside the protective bushing. The through-hole is rectangular, and a longitudinal limiting protrusion and a transverse limiting protrusion are formed on the inner wall of the through-hole. The longitudinal and transverse limiting protrusions are symmetrically arranged on the inner wall of the through-hole.

[0008] Furthermore, as described above, there are two sets of both the longitudinal and transverse limiting protrusions, and the two sets of longitudinal and transverse limiting protrusions are symmetrically distributed on the inner side of the rectangular socket hole. The longitudinal and transverse limiting protrusions are composed of hemispherical protrusions, so that arc-shaped surfaces are formed on the longitudinal and transverse limiting protrusions.

[0009] By symmetrically setting two sets of longitudinal limiting protrusions and two sets of transverse limiting protrusions on the inner side of the rectangular socket, and the limiting protrusions are hemispherical protrusions forming an arc surface, the battery cell can be limited in both longitudinal and transverse directions when it is inserted into the socket, effectively preventing the battery cell from moving axially. Compared with the traditional simple insertion fit, it improves the positioning accuracy and stability of the battery cell and enhances the support and protection effect of the battery cell.

[0010] Furthermore, as described above, the protective bushing is made of protective silicone and includes an outer mounting portion and an inner limiting portion.

[0011] The protective bushing is made of protective silicone, which has good shock absorption properties, can absorb external vibrations, reduce the transmission of vibrations to the battery cell, and reduce the axial movement of the battery cell caused by vibration.

[0012] Specifically, the outer mounting part is made of rigid material to facilitate matching and installation with the housing cavity, while the inner limiting part is made of soft material to limit the battery cell. The overall structure improves the protection performance of the support base for the battery cell and solves the problem of unsatisfactory protection effect caused by the direct installation and connection of the traditional bracket to the box.

[0013] Furthermore, as described above, the inner wall of the receiving cavity is provided with an insertion groove for the mating and holding structure. The holding structure includes multiple snap-fit ​​protrusions distributed on the outer side of the protective bushing. The protective bushing is mated and inserted into the insertion groove through the snap-fit ​​protrusions and wedge-tightly mated.

[0014] An inserting groove is arranged on the inner wall of the containing cavity, and a clamping protrusion is arranged on the outer side surface of the protective lining. The clamping protrusion is inserted and wedged tightly in cooperation with the inserting groove, so that the stable connection between the protective lining and the containing cavity is realized. This connection mode is simple and reliable, can ensure that the protective lining will not loosen during use, thereby ensuring the continuous stable support and protection of the protective lining for the battery cell, and solves the problem that the support seat may shift due to infirm connection in the traditional solution.

[0015] In the above description, further, the protection parts are symmetrically distributed on both sides of the base, and the protection parts are arranged in a "日" shape.

[0016] The protection parts are symmetrically distributed on both sides of the base and arranged in a "日" shape, which increases the overall strength and stability of the support seat. When the battery cell is subjected to external collision or vibration, the acting force can be effectively dispersed and buffered, the influence on the battery cell is reduced, the support protection effect on the battery cell is further improved, and the use reliability of the support seat is enhanced.

[0017] In the above description, further, a plurality of longitudinal limiting protrusions and transverse limiting protrusions are provided, and the longitudinal limiting protrusions and the transverse limiting protrusions are distributed in a linear array.

[0018] By arranging the longitudinal limiting protrusions and the transverse limiting protrusions distributed in a linear array, the battery cell can be limited more uniformly and comprehensively, the end part of the battery cell is effectively constrained longitudinally and transversely in the sleeving hole, which further prevents the battery cell from axial movement, and improves the stability and reliability of battery cell installation.

[0019] In the above description, further, the outer side surface of the base is respectively provided with a butt joint groove and a butt joint protrusion, and the butt joint groove and the butt joint protrusion are oppositely distributed on both sides of the base.

[0020] By oppositely arranging the butt joint groove and the butt joint protrusion on the outer side surface of the base, it is convenient for butt joint assembly among a plurality of support seats, and the support seats can be flexibly combined according to actual requirements, so as to meet the installation requirements of battery cells with different specifications.

[0021] The beneficial effects of this utility model are as follows: The inner wall of the receiving cavity is fitted with nested protective bushings, and the outer surface of the protective bushings is connected to the receiving cavity via a clamping structure, allowing the protective bushings to be securely installed within the receiving cavity. One end of the battery cell is inserted into the socket hole, so that the end of the battery cell contacts the support and bearing parts. When external vibrations are transmitted to the support base, the protective bushings can directly protect the battery cell, reducing the direct impact of the base on the battery cell under vibration and improving the stability of the battery cell installation. The longitudinal and transverse limiting protrusions can respectively limit the contact of the battery cell in the longitudinal and transverse directions, effectively preventing axial movement of the battery cell and reducing the problem of displacement caused by long-term slight movement. This further enhances the support and protection performance of the support base for the battery cell, ensuring the stability and reliability of the battery cell installation. The protective part and the clearance slot can, to a certain extent, block direct collisions between external objects and the battery cell, playing a protective role and further ensuring the installation and protection of the battery cell on the support base.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following describes the solution in further detail with reference to the accompanying drawings and embodiments.

[0031] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] In this embodiment, refer to Figures 1-6 The specific implementation of a battery cell support includes a base 1, a receiving cavity 2 formed on the base 1, an installation hole 3 formed on the top of the receiving cavity 2, a support part 4 for supporting the battery cell formed on the bottom of the base 1, a support part 5 for supporting and positioning provided in the middle of the support part 4, a through hole 6 provided on the support part 5, a protective part 7 formed on the side of the base 1, at least two through-holes 8 provided on the protective part 7, a protective bushing 9 nested in pairs on the inner wall of the receiving cavity 2, the outer side of the protective bushing 9 being connected to the receiving cavity 2 by a clamping structure, a through socket 10 provided inside the protective bushing 9, the socket 10 being rectangular in shape, and the inner wall of the socket 10 having a longitudinal limiting protrusion 11 and a transverse limiting protrusion 12 respectively, the longitudinal limiting protrusion 11 and the transverse limiting protrusion 12 being symmetrically arranged on the inner wall of the socket 10.

[0033] In this embodiment, the conductive clearance slot can reduce the overall weight of the support base while ensuring the structural strength of the protective part, thereby improving the safety and stability of the battery cell during use.

[0034] The support section stably supports the battery cell, providing basic support. The mounting section allows for more precise positioning of the battery cell, and the through-hole design may be used for connection or fixation with other components, further ensuring the stability of the battery cell's position on the support base and improving the overall reliability of the support base.

[0035] Specifically, in this embodiment, the through hole is used to pass through the battery cell connecting wire.

[0036] The longitudinal limiting protrusion 11 and the transverse limiting protrusion 12 are each provided in two sets, and the two sets of longitudinal limiting protrusion 11 and the two sets of transverse limiting protrusion 12 are symmetrically distributed on the inner side of the rectangular socket hole 10. The longitudinal limiting protrusion 11 and the transverse limiting protrusion 12 are composed of hemispherical protrusions, so that arc-shaped surfaces are formed on the longitudinal limiting protrusion 11 and the transverse limiting protrusion 12.

[0037] By symmetrically setting two sets of longitudinal limiting protrusions 11 and two sets of transverse limiting protrusions 12 on the inner side of the rectangular socket 10, and the limiting protrusions are hemispherical protrusions forming an arc surface, the battery cell can be limited in both longitudinal and transverse directions when it is inserted into the socket 10, effectively preventing the battery cell from moving axially. Compared with the traditional simple insertion fit, it improves the positioning accuracy and stability of the battery cell and enhances the support and protection effect of the battery cell.

[0038] Specifically, the longitudinal limiting protrusion 11 and the transverse limiting protrusion 12 can contact the outer side of the battery cell to form a wedge, so that the battery cell can be installed and protected stably.

[0039] The protective bushing 9 is made of protective silicone and includes an outer mounting part 13 and an inner limiting part 14.

[0040] The protective bushing 9 is made of protective silicone. Silicone has good shock absorption properties, which can absorb external vibrations, reduce the transmission of vibrations to the battery cell, and reduce the axial movement of the battery cell caused by vibration.

[0041] Specifically, the outer mounting part 13 is made of rigid material to facilitate matching and installation with the receiving cavity 2, while the inner limiting part 14 is made of soft material to limit the battery cell. The overall structure improves the protection performance of the support base for the battery cell and solves the problem of unsatisfactory protection effect caused by the direct installation and connection between the traditional bracket and the box.

[0042] Specifically, the protective bushing 9 is made of two types of silicone rubber (or other high-performance elastomers) with different hardnesses bonded together through a co-vulcanization process. For example, the outer layer is a high-hardness silicone rubber (such as Shore A 70-80 degrees), and the inner layer is a low-hardness silicone rubber (such as Shore A 30-40 degrees).

[0043] The inner wall of the receiving cavity 2 is provided with an insertion groove 15 for the mating and holding structure. The holding structure includes a snap-fit ​​protrusion 16, which is distributed on the outer side of the protective bushing 9. The protective bushing 9 is mated and inserted into the insertion groove 15 through the snap-fit ​​protrusion 16 and wedge-tightly mated.

[0044] An insertion slot 15 is provided on the inner wall of the receiving cavity 2, and a snap-fit ​​protrusion 16 is provided on the outer side of the protective bushing 9. The snap-fit ​​protrusion 16 is matched with the insertion slot 15 and inserted and wedge tightly, so as to achieve a stable connection between the protective bushing 9 and the receiving cavity 2. This connection method is simple and reliable, and can ensure that the protective bushing 9 will not loosen during use, thereby ensuring the continuous and stable support and protection of the battery cell by the protective bushing 9. This solves the problem that the support seat may shift due to the insecure connection in the traditional solution.

[0045] Specifically, the clamping protrusions 16 are distributed around the outer mounting portion 13, and the clamping protrusions 16 and the outer mounting portion 13 are of an integrally formed structure.

[0046] The protection portions 7 are symmetrically distributed on both sides of the base 1, and the protection portions 7 are arranged in a "ri" shape (a Chinese character shaped like the numeral 8).

[0047] The protection portions 7 are symmetrically distributed on both sides of the base 1 and arranged in a "ri" shape, which increases the overall strength and stability of the support seat. When the battery cell is subjected to external collision or vibration, the acting force can be effectively dispersed and buffered, the influence on the battery cell is reduced, the supporting and protection effect on the battery cell is further improved, and the use reliability of the support seat is enhanced.

[0048] A plurality of the longitudinal limiting protrusions 11 and the transverse limiting protrusions 12 are provided, and the longitudinal limiting protrusions 11 and the transverse limiting protrusions 12 are distributed in a linear array.

[0049] Providing the longitudinal limiting protrusions 11 and the transverse limiting protrusions 12 distributed in a linear array can limit the battery cell more uniformly and comprehensively. The end part of the battery cell is effectively constrained longitudinally and transversely in the socket hole 10, which further prevents the battery cell from axial movement and improves the stability and reliability of battery cell installation.

[0050] The outer side surface of the base 1 is respectively provided with a docking groove 17 and a docking protrusion 18, and the docking groove 17 and the docking protrusion 18 are oppositely distributed on both sides of the base 1.

[0051] The docking groove 17 and the docking protrusion 18 are oppositely arranged on the outer side surface of the base 1, which facilitates docking and assembling among a plurality of support seats. The support seats can be flexibly combined according to actual requirements to meet the installation requirements of battery cells of different specifications.

[0052] The specific application principle in this embodiment is as follows:

[0053] The protective bushings 9 are nested and installed in pairs within the receiving cavity 2 of the base 1, so that the outer surface of the protective bushings 9 is connected to the insertion slot 15 through the snap-fit ​​protrusion 16. The protective bushings 9 can be securely installed in the receiving cavity 2. One end of the battery cell is inserted into the socket 10, so that the end of the battery cell contacts the support part 4 and the support part 5. At the same time, another support seat is fitted on the top of the battery cell, so that both ends of the battery cell can be installed and supported. When external vibration is transmitted to the support seat, the protective bushings 9 can directly provide a certain degree of protection for the battery cell, reducing the impact of vibration on the battery cell from the base 1. The direct impact of this improves the stability of the battery cell installation. The longitudinal and lateral limiting protrusions 12 can respectively limit the contact of the battery cell in the longitudinal and lateral directions, effectively preventing the battery cell from axially moving and reducing the problem of displacement caused by long-term slight movement. This further enhances the support and protection performance of the support base for the battery cell, ensuring the stability and reliability of the battery cell installation. By setting the protective part 7 and the clearance slot 8 on the side of the base 1, the direct collision of external objects with the battery cell can be blocked to a certain extent, playing a role in protecting the battery cell and further ensuring the installation and support protection of the battery cell on the support base.
