Description

Technical Field

[0001] This application relates to the field of battery pack technology, and in particular to a cell mounting structure and battery pack. Background Technology

[0002] Currently, battery cells in battery packs are mostly fixed to the battery pack casing using bolts or adhesive to ensure the stability of the cells during installation. However, bolted connections require tools for installation and removal, making assembly complex and reducing production efficiency. Adhesive bonding, on the other hand, is highly susceptible to adhesion strength due to the properties of the adhesive and the application process, potentially leading to cell loosening and compromising battery safety. Utility Model Content

[0003] In view of this, this application aims to propose a cell mounting structure that simplifies the cell mounting process while ensuring the cell mounting effect.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: A battery cell mounting structure includes a base connected to the battery pack housing, a movable component rotatably mounted on the base, and a snap-fit ​​seat located at the bottom of the battery cell. The base is provided with a support platform for placing the battery cell. At least one side of the support platform is provided with the movable member. The movable member includes an abutment part and a snap-fit ​​part. The snap-fit ​​part is provided with a buckle. Both the buckle and the abutting part extend toward the side where the battery cell is located, and the buckle base is provided with a buckle groove; As the battery cell is placed on the support platform, the abutting part can be pressed by the snap-fit ​​seat, causing the snap-fit ​​part to rotate toward the battery cell side and the snap-fit ​​into the slot.

[0005] Furthermore, the end of the latching part is provided with a pressing part, which extends away from the buckle; the pressing part is pressed to drive the latching part to rotate away from the battery cell and disengage the buckle from the slot, and as the latching part rotates, the abutting part can push the latching seat upward.

[0006] Furthermore, the pressing part includes a pressing block extending to the other side of the snap-fit ​​part relative to the buckle; the pressing block is provided with a concave arc-shaped pressing surface, and / or, the pressing block is provided with a pattern.

[0007] Furthermore, the base is provided with a limiting plate, which is located on the side of the movable member away from the support platform; the limiting plate is used to abut against the snap-fit ​​part to limit the rotation angle of the movable member.

[0008] Furthermore, the abutting portion includes an abutting block extending toward one side of the battery cell, and the locking portion includes an upwardly extending locking block; the abutting block and the locking block are perpendicular to each other, and the connection between the abutting block and the locking block is hinged to the base.

[0009] Furthermore, when the buckle is engaged with the battery cell, the top of the support platform is flush with one side of the abutment block.

[0010] Furthermore, the end of the abutment block is provided with a snap-fit ​​protrusion, and the support platform is provided with a snap-fit ​​groove; when the buckle is snapped into the slot, the snap-fit ​​protrusion snaps into the snap-fit ​​groove.

[0011] Furthermore, the card holder is integrally formed on the bottom of the battery cell housing.

[0012] Furthermore, the movable parts are configured as a plurality of ones distributed on opposite sides of the support platform, and the snap-fit ​​slots are configured as a plurality of ones corresponding one-to-one with each of the movable parts.

[0013] Compared with related technologies, this application has the following advantages: (1) The battery cell mounting structure described in this application, through the cooperation of the movable part and the snap-fit ​​seat, allows the snap-fit ​​seat at the bottom of the battery cell to press the abutment part, thereby driving the snap-fit ​​part to rotate and causing the snap-fit ​​to snap into the slot, which can realize the quick snap-fit ​​and fixation of the battery cell and the base, simplifying the battery cell installation operation, and thus facilitating the installation and fixation of the battery cell in the battery pack.

[0014] (2) By setting the pressing part, the pressing part can be pressed to drive the snap-fit ​​part to rotate away from the battery cell, so that the snap-fit ​​can be disengaged and the abutting part can be pushed upward against the snap-fit ​​seat, so that the battery cell connected to the snap-fit ​​seat can be separated from the base, thereby simplifying the battery cell disassembly operation and facilitating the disassembly and maintenance of the battery cell.

[0015] (3) By setting the arc-shaped pressing surface on the pressing block, the fit between the hand and the pressing block can be improved when pressing the pressing block, making the pressing operation more comfortable. At the same time, the pattern setting can increase the friction between the hand and the pressing block, and prevent slippage during the pressing process.

[0016] (4) By limiting the rotation angle of the moving part by the limiting plate, it can prevent the moving part from rotating too far away from the battery cell during the battery cell installation process, which would prevent the card holder from effectively contacting the abutment part and thus prevent the moving part from rotating into place, thereby ensuring the smoothness of the battery cell installation process.

[0017] (5) By setting the abutment block and the snap block to be perpendicular to each other, the moving part can fit the shape of the bottom edge of the snap block after the battery cell is installed in place. At the same time, the snap block can be used to form a limiting constraint on the snap block, further improving the fixing effect of the battery cell.

[0018] (6) By setting one side of the abutment block to be flush with the top of the support platform, the support platform and the abutment block together form a stable support for the card seat, avoiding the tilting or uneven force on the battery cell due to the height difference between the support platform and the abutment block, thereby improving the stability of the battery cell installation.

[0019] (7) By the matching of the snap-fit ​​protrusion and the snap-fit ​​groove, the snap-fit ​​protrusion can engage with the snap-fit ​​groove while the snap-fit ​​is snapped into the groove, thereby restricting the rotation of the moving part and preventing the snap-fit ​​from accidentally coming out of the groove, thus ensuring the reliability of the snap-fit.

[0020] (8) By integrally molding the connector and the cell housing, the connection strength of the connector at the bottom of the cell can be improved, and the connector can be prevented from falling off. At the same time, the integral molding design can eliminate the assembly steps between the connector and the cell housing, which simplifies the cell manufacturing process to a certain extent.

[0021] (9) By distributing the movable parts on opposite sides of the support platform, the opposite sides of the snap-fit ​​base can be fixed, avoiding the single-layer force on the snap-fit ​​base that could cause the battery cell to tilt or be misaligned during installation. At the same time, the multiple snap-fit ​​slots correspond one-to-one with the multiple movable parts, which can form a multi-point fixation of the snap-fit ​​base, further improving the connection effect between the battery cell and the base, thereby improving the installation stability of the battery cell.

[0022] Another object of this application is to provide a battery pack having the cell mounting structure described above.

[0023] The battery pack and / or the cell mounting structure described in this application have the same technical effects as related technologies, and will not be repeated here. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides a cell mounting structure suitable for mounting a cell 4 on a battery pack housing.

[0032] In related technologies, the battery cells 4 in the battery pack are mostly fixed to the battery pack casing using bolt connections or adhesive bonding. However, bolt connections require tools for installation and removal, making assembly complex and reducing production efficiency. Adhesive bonding, on the other hand, is greatly affected by the adhesive properties and application process, potentially leading to loosening of the battery cells 4 and compromising battery safety.

[0033] In view of this, in order to overcome the shortcomings of related technologies, the cell mounting structure of this embodiment combines... Figures 1 to 3 As shown, the overall design includes a base 1 that connects to the battery pack housing, a movable part 2 that is rotatably mounted on the base 1, and a snap-fit ​​seat 3 located at the bottom of the battery cell 4.

[0034] The base 1 has a support platform 101 for placing the battery cell 4. At least one side of the support platform 101 has a movable member 2, which includes an abutment portion and a locking portion. The locking portion has a latch 203. Both the latch 203 and the abutment portion extend towards the side where the battery cell 4 is located, and the locking seat 3 has a slot 301. As the battery cell 4 is placed on the support platform 101, the abutment portion can be pressed by the locking seat 3, causing the locking portion to rotate towards the battery cell 4 and engaging the latch 203 into the slot 301.

[0035] Thus, through the cooperation between the movable part 2 and the snap-fit ​​seat 3, the snap-fit ​​seat 3 at the bottom of the battery cell 4 can press the abutment part to drive the snap-fit ​​part to rotate so that the snap-fit ​​203 can be snapped into the slot 301, thereby realizing the quick snap-fit ​​and fixation of the battery cell 4 and the base 1, simplifying the installation operation of the battery cell 4, and thus facilitating the installation and fixation of the battery cell 4 in the battery pack.

[0036] Based on the above general introduction, specifically, in this embodiment, the base 1 is connected inside the battery pack housing, and the base 1 can be integrally formed with the battery pack housing to ensure the stability of the battery cell 4 inside the battery pack housing after the base 1 and the battery cell 4 are snapped together.

[0037] In some exemplary embodiments, the end of the latching portion is provided with a pressing portion that extends away from the latch 203. The pressing portion is pressed, causing the latching portion to rotate away from the battery cell 4 and disengaging the latch 203 from the slot 301. As the latching portion rotates, the abutment portion can push the latching seat 3 upward.

[0038] By setting the pressing part, pressing the pressing part can drive the locking part to rotate away from the battery cell 4, causing the buckle 203 to disengage, and the abutting part to push upward against the locking seat 3, so that the battery cell 4 connected to the locking seat 3 can be separated from the base 1, thereby simplifying the disassembly operation of the battery cell 4 and facilitating the disassembly and maintenance of the battery cell 4.

[0039] In some exemplary embodiments, the pressing part includes a pressing block 5 extending to the other side of the engaging part relative to the latch 203. The pressing block 5 is provided with a concave arc-shaped pressing surface 501. By providing the arc-shaped pressing surface 501 on the pressing block 5, the fit between the hand and the pressing block 5 can be improved when pressing the pressing block 5, making the pressing operation more comfortable.

[0040] Meanwhile, the pressing block 5 has a pattern, which can increase the friction between the hand and the pressing block 5 and prevent slippage during pressing.

[0041] In specific implementation, the pressing block 5 of this embodiment is provided with an arc-shaped pressing surface 501 and a pattern, and the pattern can preferably be set in the arc-shaped pressing surface 501.

[0042] In some exemplary embodiments, a limiting plate 102 is provided on the base 1, and the limiting plate 102 is located on the side of the movable member 2 away from the support platform 101. The limiting plate 102 is used to abut against the snap-fit ​​portion to limit the rotation angle of the movable member 2.

[0043] It is understandable that if the rotating tape of the movable part 2 is too large on the side away from the battery cell 4, the abutment part will be in an upward orientation. At this time, when the locking seat 3 presses on the abutment part, the angle of the abutment part will be poor, which will affect the locking seat 3 from driving the movable part 2 to rotate, and will not be conducive to the engagement between the movable part 2 and the locking seat 3.

[0044] By limiting the rotation angle of the movable part 2 by the limiting plate 102, it is possible to prevent the movable part 2 from rotating excessively away from the battery cell 4 during the installation process, which would prevent the locking seat 3 from effectively contacting the abutment part and thus prevent the movable part 2 from rotating into place, thereby ensuring the smoothness of the battery cell 4 installation process.

[0045] In some exemplary embodiments, the abutting portion includes an abutting block 201 extending toward one side of the battery cell 4, and the locking portion includes an upwardly extending locking block 202. The abutting block 201 and the locking block 202 are perpendicular to each other, and the connection between the abutting block 201 and the locking block 202 is hinged to the base 1.

[0046] By setting the abutment block 201 and the locking block 202 to be perpendicular to each other, after the battery cell 4 is installed in place, the movable part 2 can fit the shape of the bottom edge of the locking seat 3. At this time, the locking block 202 is in contact with the side of the locking seat 3, so that the locking block 202 constitutes a limiting constraint on the locking seat 3. Thus, the locking block 202 itself, as well as the buckle 203 on the locking block 202, can simultaneously constrain the battery cell 4 to prevent the battery cell 4 from coming off upward or shaking in the horizontal direction, further improving the fixing effect of the battery cell 4.

[0047] In some exemplary embodiments, when the clip 203 is engaged with the battery cell 4, the top of the support platform 101 is flush with one side of the abutment block 201. By setting one side of the abutment block 201 to be flush with the top of the support platform 101, the support platform 101 and the abutment block 201 together form a stable support for the locking seat 3, avoiding the battery cell 4 from being tilted or subjected to uneven force due to the height difference between the support platform 101 and the abutment block 201, thereby improving the stability of the battery cell 4 installation.

[0048] In some exemplary embodiments, the end of the abutment block 201 is provided with a snap-fit ​​protrusion 2011, and the support platform 101 is provided with a snap-fit ​​groove 1011. When the buckle 203 is engaged with the slot 301, the snap-fit ​​protrusion 2011 is engaged in the snap-fit ​​groove 1011.

[0049] It is understandable that, without the snap-fit ​​protrusion 2011 and snap-fit ​​groove 1011, if the battery cell 4 moves upward due to external force, the snap-fit ​​seat 3 that moves with the battery cell 4 will push against the snap fastener 203, which will easily drive the movable part 2 to rotate and cause the snap fastener 203 to completely disengage from the slot 301, ultimately causing the battery cell 4 to separate from the base 1.

[0050] Therefore, by the engagement of the snap-fit ​​protrusion 2011 and the snap-fit ​​groove, when the snap-fit ​​203 is snapped into the snap-fit ​​groove 301, the snap-fit ​​protrusion 2011 can engage with the snap-fit ​​mating groove 1011 to restrict the rotation of the movable part 2, keep the abutment block 201 flush with the support platform 101, thereby preventing the snap-fit ​​203 from accidentally coming out of the snap-fit ​​groove 301 and ensuring the reliability of the snap-fit.

[0051] In some exemplary embodiments, the connector 3 is integrally formed on the bottom of the cell 4's housing. By integrally forming the connector 3 with the cell 4's housing, the connection strength of the connector 3 at the bottom of the cell 4 can be improved, preventing the connector 3 from falling off. At the same time, the integral design can eliminate the assembly steps between the connector 3 and the cell 4's housing, simplifying the manufacturing process of the cell 4 to some extent.

[0052] In some exemplary embodiments, the movable members 2 are configured as a plurality of ones located on opposite sides of the support platform 101, and the snap-fit ​​slots are configured as a plurality of ones corresponding one-to-one with each movable member 2.

[0053] By distributing the movable parts 2 on opposite sides of the support platform 101, the corresponding sides of the snap-fit ​​base 3 can be fixed, preventing the battery cell 4 from tilting or shifting due to single-layer stress on the snap-fit ​​base 3. At the same time, the multiple snap-fit ​​slots correspond one-to-one with the multiple movable parts 2, forming a multi-point fixation of the snap-fit ​​base 3, further improving the connection effect between the battery cell 4 and the base 1, thereby improving the installation stability of the battery cell 4.

[0054] In specific implementation, each of the opposite sides of the support platform 101 in this embodiment is provided with a movable member 2, and the snap-fit ​​slots are configured as two on opposite sides of the snap-fit ​​base 3. Of course, on any side of the support platform 101, multiple movable members 2 can also be provided to ensure that if a single movable member 2 is damaged, the other movable members 2 can still effectively fix the snap-fit ​​base 3, that is, the battery cell 4, thereby improving the redundancy of the battery cell installation structure.

[0055] It is worth noting that, regarding the cell mounting structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still based on... Figures 1 to 3 As shown.

[0056] The cell mounting structure of this embodiment includes a base 1 connected to the battery pack housing, a movable part 2 rotatably disposed on the base 1, and a snap-fit ​​seat 3 disposed at the bottom of the cell 4.

[0057] The base 1 has a support platform 101 for placing the battery cell 4. At least one side of the support platform 101 has a movable member 2, which includes an abutment portion and a locking portion. The locking portion has a latch 203. Both the latch 203 and the abutment portion extend towards the side where the battery cell 4 is located, and the locking seat 3 has a slot 301. As the battery cell 4 is placed on the support platform 101, the abutment portion can be pressed by the locking seat 3, causing the locking portion to rotate towards the battery cell 4 and engaging the latch 203 into the slot 301.

[0058] Furthermore, the abutment portion includes an abutment block 201 extending towards the battery cell 4, and the locking portion includes an upwardly extending locking block 202. The abutment block 201 and the locking block 202 are perpendicular to each other, and the connection between the abutment block 201 and the locking block 202 is hinged to the base 1. When the latch 203 is engaged with the battery cell 4, the top of the support platform 101 is flush with one side of the abutment block 201. The end of the abutment block 201 is provided with a locking protrusion 2011, and the support platform 101 is provided with a locking mating groove 1011. When the latch 203 is engaged with the latching groove 301, the locking protrusion 2011 is engaged within the locking mating groove 1011.

[0059] Additionally, the end of the latching portion is provided with a pressing portion, which extends away from the latch 203. When the pressing portion is pressed, it drives the latching portion to rotate away from the battery cell 4, causing the latch 203 to disengage from the slot 301. As the latching portion rotates, the abutment portion can push the latching seat 3 upwards. The pressing portion includes a pressing block 5 extending relative to the latch 203 to the other side of the latching portion. The pressing block 5 has a concave arc-shaped pressing surface 501 and a pattern.

[0060] Furthermore, a limiting plate 102 is provided on the base 1, located on the side of the movable member 2 away from the support platform 101. The limiting plate 102 is used to abut against the snap-fit ​​part to limit the rotation angle of the movable member 2. The snap-fit ​​seat 3 is integrally formed on the bottom of the housing of the battery cell 4. The movable members 2 are configured as multiple ones distributed on opposite sides of the support platform 101, and the snap-fit ​​slots are configured as multiple ones corresponding one-to-one with each movable member 2.

[0061] In the preferred embodiment of the above-mentioned cell mounting structure, the specific settings and arrangements of the movable part 2, the snap-fit ​​protrusion 2011, the snap-fit ​​mating part, etc. can still be referred to the descriptions in the above-mentioned exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the movable part 2, the snap-fit ​​protrusion 2011, the snap-fit ​​mating part, etc. can also be referred to the descriptions in the above-mentioned exemplary embodiments.

[0062] The battery cell mounting structure of this embodiment adopts the above design. Through the cooperation of the movable part 2 and the snap-fit ​​seat 3, the snap-fit ​​seat 3 at the bottom of the battery cell 4 can press the abutment part to drive the snap-fit ​​part to rotate so that the buckle 203 is snapped into the slot 301. This can realize the quick snap-fit ​​and fixation of the battery cell 4 and the base 1, simplifying the installation operation of the battery cell 4, thereby facilitating the installation and fixation of the battery cell 4 in the battery pack, and has good practicality.

[0063] An embodiment of the second aspect of this application provides a battery pack having the cell mounting structure described above.

[0064] The cell mounting structure of this embodiment enables the rapid installation and removal of the cell 4 in the battery pack housing. While ensuring the fixation effect of the cell 4, it simplifies the installation and removal steps of the cell 4, so as to facilitate the assembly and maintenance of each cell 4 in the cell pack.

[0065] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
