[0002] A battery cell is the smallest power supply unit in a battery pack. Typically, battery cells in a battery pack are connected in series or parallel to connect to external circuits or systems.

[0003] The conventional methods for securing battery cells in a battery pack are adhesive bonding or bracket connection. Adhesive-bonded cells are inconvenient to disassemble for maintenance, while bracket-connected cells offer better detachability. However, conventional cell brackets are integrated, with multiple cells mounted on the same bracket. This necessitates redesigning the bracket when different numbers of cells or cell specifications are required, hindering the improvement of the versatility of the cell bracket system. Utility Model Content

[0004] In view of this, this application aims to provide a cell support structure to improve the versatility of the cell support structure.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A battery cell support includes two clamping portions and an adjusting portion connected between the two clamping portions; The adjustment part can adjust the distance between the two clamping parts so that the two clamping parts are clamped together on the battery cell; Multiple battery cell brackets can be connected together in sequence, and adjacent clamping parts between adjacent battery cell brackets can be detachably connected, so that the battery cells clamped by each battery cell bracket are arranged at intervals along a preset direction.

[0006] Furthermore, the adjusting part includes a screw with opposite thread directions at both ends, and the two clamping parts are screwed to the two ends of the screw respectively.

[0007] Furthermore, the screw is provided with a handle, which can be operated to rotate the screw.

[0008] Furthermore, a guide structure is provided between the two clamping parts, which can guide the two clamping parts to move closer or further apart in a preset direction.

[0009] Furthermore, the guide structure includes guide holes provided on each of the clamping portions, and a first guide rod arranged along the preset direction; The two ends of the first guide rod are respectively inserted into the guide holes of the two clamping parts.

[0010] Furthermore, each of the clamping parts includes a second guide rod, two clamping blocks slidably connected to both ends of the second guide rod, and a locking member capable of fixing each clamping block to the second guide rod; The clamps together form a receiving space in which at least a portion of the battery cell can be embedded.

[0011] Furthermore, each of the clamping blocks has an extension section, in which the second guide rod passes; The locking element is located on the extension section and can abut against the second guide rod.

[0012] Furthermore, the cell support includes a third guide rod arranged along the preset direction, and the second guide rods of the two clamping portions are slidably connected to the third guide rod.

[0013] Furthermore, the locking element includes a bolt screwed onto the extension section, the bolt being capable of abutting against the second guide rod.

[0014] Furthermore, one of the clamping parts is provided with a slot extending perpendicular to the preset direction, and the other clamping part is provided with an insert that is adapted to the shape of the slot.

[0015] Compared with related technologies, this application has the following advantages: (1) The cell bracket described in this application, by setting an adjustment part and a clamping part, allows the clamping parts of multiple cell brackets to be detachably connected, enabling multiple brackets to be connected in series, so that the cells can be arranged in a preset direction to meet the assembly requirements of battery packs of different capacities, which is beneficial to improving the versatility of the cell bracket; at the same time, the adjustment part has the adjustment capability to adjust the spacing of the clamping parts, so that the two clamping parts can clamp cells of different sizes, further enhancing the adaptability of the cell bracket to cells of different specifications, which is beneficial to improving versatility.

[0016] (2) The dual-rotation screw can drive the two clamping parts to move in opposite directions simultaneously by rotating, ensuring that the clamping force of the two clamping parts is evenly distributed, making the clamped battery cell posture more regular. At the same time, the thread structure, due to its self-locking property, can naturally maintain the position of the clamping part when there is no external force, and has strong clamping stability.

[0017] (3) The handle makes it easy for the operator to turn the screw without the need for additional tools and saves physical effort.

[0018] (4) The guide structure is used to guide the movement of the two clamping parts, so that the two clamping parts move stably, reduce the non-axial stress on the screw, the screw is not easy to bend under force and the clamping parts are not easy to tilt, which is conducive to improving the adjustment accuracy.

[0019] (5) The guide hole and the first guide rod have a simple and practical structure. The cooperation between the first guide rod and the guide hole can effectively limit the movement direction of the clamping part, so that the clamping part can move stably. The processing and assembly are relatively convenient and the cost is low.

[0020] (6) The clamping part adopts the structure of a second guide rod, a clamping block and a locking member. The clamping block can slide on the second guide rod and can adjust its position according to the shape and size of the battery cell to form a suitable accommodating space. The locking member can fix the clamping block, thereby realizing flexible clamping of battery cells of different specifications. It has strong adaptability and is conducive to improving the versatility of the battery cell bracket.

[0021] (7) The extension section of the clamping block can enhance the anti-tilting ability of the clamping block, so that the clamping block can maintain a better posture to adapt to the battery cell, and enhance the clamping stability of the clamping block. At the same time, the locking part can firmly fix the position of the clamping block on the second guide rod, so that the clamping block will not easily loosen during use, thus ensuring the clamping effect on the battery cell.

[0022] (8) A third guide rod is provided so that the second guide rods of the two clamping parts are slidably connected to it, which further improves the stability and guidance of the movement of the clamping parts; the locking part is made of bolts, which is easy to operate. The clamping block can be fixed and released by tightening or loosening the bolts, which is convenient and quick.

[0023] (9) One clamping part is equipped with a slot and the other with a plug. This structure facilitates the detachable connection between adjacent cell brackets. The connection method is simple and reliable, and can quickly realize the assembly and disassembly of multiple cell brackets, which is beneficial to the production and maintenance of battery packs.

[0024] This application also proposes a battery pack having the aforementioned cell support structure.

[0025] The battery pack described in this application has the aforementioned cell support structure. By providing an adjustment section and a clamping section, the clamping sections of multiple cell supports can be detachably connected, enabling the series connection of multiple supports. This allows the cells to be arranged in a preset direction, adapting to the assembly requirements of different capacitance values ​​in the battery pack. This improves the versatility of the cell support structure and enhances the flexibility of cell arrangement in the battery pack. Simultaneously, the adjustment section's adjustable capability allows for adjustment of the spacing between the clamping sections, enabling two clamping sections to hold cells of different sizes. This further enhances the cell support structure's adaptability to different cell specifications, enriching the range of cell specifications that can be configured in the battery pack.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0031] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. 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.

[0032] 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.

[0033] An embodiment of the first aspect of this application provides a battery cell support that can adapt to various specifications and quantities of battery cells, and has good versatility.

[0034] A battery cell is the smallest power supply unit in a battery pack. Typically, battery cells in a battery pack are connected in series or parallel to connect to external circuits or systems.

[0035] In related technologies, the conventional methods for fixing battery cells in battery packs are adhesive bonding or bracket bonding. Adhesive-bonded cells are inconvenient to disassemble for maintenance, while bracket bonding provides better removability. However, conventional cell brackets are integrated, with multiple cells mounted on the same bracket. This means that when different numbers of cells or different cell specifications are needed, the bracket needs to be redesigned, which is not conducive to improving the versatility of the cell bracket system.

[0036] In view of this, in order to overcome the shortcomings of related technologies, the cell support in this embodiment combines... Figures 1 to 3 As shown, the overall design includes two clamping parts 1 and an adjusting part 2 connected between the two clamping parts 1.

[0037] The adjusting part 2 can adjust the distance between the two clamping parts 1 so that the two clamping parts 1 are clamped together on the battery cell 5. Multiple battery cell brackets can be connected together in sequence, and the adjacent clamping parts 1 between adjacent battery cell brackets can be detachably connected, so that the battery cells 5 clamped by each battery cell bracket are arranged at intervals along a preset direction.

[0038] Therefore, by setting the adjustment part 2 and the clamping part 1, the clamping parts 1 of multiple cell brackets can be detachably connected, enabling multiple brackets to be connected in series. This allows the cell 5 to be arranged in a preset direction, adapting to the assembly requirements of battery packs of different capacities, and improving the versatility of the cell bracket. Simultaneously, the adjustment capability of the adjustment part 2 allows for adjustment of the spacing between the clamping parts 1, enabling two clamping parts 1 to clamp cell 5 of different sizes, further enhancing the adaptability of the cell bracket to cell 5 of different specifications, and improving versatility.

[0039] Based on the above general introduction, specifically, the preset direction is the stacking direction of the battery cells 5. For example, when the battery cells 5 are square battery cells 5 or blade battery cells 5, the preset direction is the width direction of the battery cells 5. By setting brackets on each battery cell 5, the battery cells 5 are arranged sequentially at intervals along the width direction.

[0040] Combination Figure 3 and Figure 4 As shown, in some exemplary embodiments, the adjusting part 2 includes a screw 201 with oppositely oriented threads at both ends, and two clamping parts 1 are screwed to the two ends of the screw 201 respectively.

[0041] With this configuration, the dual-rotation screw 201 can synchronously drive the two clamping parts 1 to move in opposite directions, ensuring that the clamping force of the two clamping parts 1 is evenly distributed, making the clamped battery cell 5 more regular in posture. At the same time, due to its self-locking property, the thread structure can naturally maintain the position of the clamping part 1 when there is no external force, and has strong clamping stability.

[0042] It should be noted that there can be one or two screws 201 between the two clamping parts 1. When two screws 201 are arranged, both screws 201 need to be rotated simultaneously to make the two clamping parts 1 move in a coordinated manner. Of course, in addition to adopting the form of a double-direction screw, the screw 201 can also adopt the form of a single-direction screw, with one end of the screw pivotally connected to one clamping part 1 around itself as an axis, and the other end screwed to the other clamping part 1.

[0043] Based on the adjusting section 2, including the screw 201, continue to refer to Figure 3 and Figure 4 In some exemplary embodiments, the screw 201 is provided with a handle 202, which can be operated to rotate the screw 201. The handle 202 makes it convenient for the operator to turn the screw 201 without the need for additional tools and saves physical effort.

[0044] The handle 202 can take the form of a handle, handwheel, knob, etc., which can turn the screw 201 by manually operating the handle 202; the handle 202 can also take the form of a structure that cooperates with tools, such as a hexagonal prism or a square prism, so that the screw 201 can be turned using a wrench-like tool.

[0045] Still combined Figure 3 and Figure 4 As shown, in some exemplary embodiments, a guide structure 3 is provided between the two clamping parts 1. The guide structure 3 can guide the two clamping parts 1 to move closer or further apart in a preset direction. The guide structure 3 is used to guide the movement of the two clamping parts 1, so that the two clamping parts 1 move stably, reducing the non-axial stress on the screw 201. The screw 201 is not easily bent by force and the clamping parts 1 are not easily tilted, which helps to improve the adjustment accuracy.

[0046] For example, based on the provision of a guide structure 3 between the two clamping parts 1, in some exemplary embodiments, the guide structure 3 includes a guide hole 302 provided on each clamping part 1, and a first guide rod 301 arranged in a preset direction. The two ends of the first guide rod 301 pass through the guide holes 302 of the two clamping parts 1 respectively. The first guide rod 301 is arranged parallel to the screw 201.

[0047] The guide hole 302 and the first guide rod 301 have a simple and practical structure. The cooperation between the first guide rod 301 and the guide hole 302 can effectively limit the movement direction of the clamping part 1, so that the clamping part 1 can move stably. Moreover, the processing and assembly are relatively convenient and the cost is low.

[0048] Preferably, anti-detachment ends 3011 with larger diameters can be provided at both ends of the first guide rod 301, so that the end of the first guide rod has a stepped shaft structure, and the anti-detachment ends 3011 are slidably disposed in the guide hole 302. The anti-detachment ends 3011 are used to prevent the end of the first guide rod from detaching from the guide hole 302, thereby causing the guiding function to fail.

[0049] Reference Figure 1 and Figure 3 In some exemplary embodiments, each clamping portion 1 of the cell holder includes a second guide rod 101, two clamping blocks 102 slidably connected to both ends of the second guide rod 101, and a locking member 103 capable of fixing each clamping block 102 to the second guide rod 101. The clamping blocks 102 collectively enclose a receiving space, within which at least a portion of the cell 5 can be embedded. The second guide rods 101 of the two clamping portions 1 are arranged parallel to each other. Specifically, the receiving space can accommodate one end of the cell 5, allowing the clamping portion to clamp onto that end of the cell 5.

[0050] The clamping part 1 adopts the structure of a second guide rod 101, a clamping block 102 and a locking member 103. The clamping block 102 can slide on the second guide rod 101 and can adjust its position according to the shape and size of the battery cell 5 to form a suitable accommodating space. The locking member 103 can fix the clamping block 102, thereby realizing flexible clamping of battery cells 5 of different specifications. It has strong adaptability and is conducive to improving the versatility of the battery cell bracket.

[0051] Taking the square battery cell 5 as an example, the clamping block 102 is clamped at the four corners on one side of the square battery cell 5 along its length direction. It consists of three rectangular plates, which are in contact with the three adjacent surfaces of the battery cell 5 respectively. One of the rectangular plates is located on the side of the battery cell 5 that extends along its length and height direction, so that after the two battery cell supports are assembled together, the battery cells 5 on the battery cell supports are kept apart to prevent short circuits, corrosion and unnecessary chemical reactions.

[0052] Reference Figure 3 As shown, based on the second guide rod 101 provided between the clamping blocks 102 and locked by the locking member 103, in some exemplary embodiments, each clamping block 102 has an extension 1021 in which the second guide rod 101 passes. The locking member 103 is provided on the extension 1021 and is capable of abutting against the second guide rod 101.

[0053] In this way, the extension section 1021 of the clamping block 102 can enhance the anti-tilting ability of the clamping block 102, so that the clamping block 102 can maintain a better posture to fit the battery cell 5, and enhance the clamping stability of the clamping block 102. At the same time, the locking member 103 can firmly fix the position of the clamping block 102 on the second guide rod 101, so that the clamping block 102 will not easily loosen during use, thus ensuring the clamping effect on the battery cell 5.

[0054] It is understandable that two sets of guide structures 3 and two screws 201 can be set between the two clamping parts 1. That is, screws 201 and guide structures 3 can be set simultaneously between the two clamping blocks 102 on the same side of the two clamping parts 1, which is beneficial to improving the stability of the battery cell bracket in clamping the battery cell 5.

[0055] In some exemplary embodiments, the locking member 103 is provided on the extension section 1021. The locking member 103 includes a bolt screwed onto the extension section 1021, which abuts against the second guide rod 101. The bolt used for the locking member 103 facilitates operation; the clamping block 102 can be fixed and released quickly and easily by tightening or loosening the bolt.

[0056] Of course, in addition to bolts, a pin can also be used to fix the position of the second guide rod 101 on the extension section 1021 by passing through the extension section 1021 and the second guide rod 101. Preferably, two or more bolts can be provided along the extension section 1021 to improve the connection strength between the extension section 1021 and the second guide rod 101.

[0057] Reference Figures 1 to 3 , Figure 5 As shown, in some exemplary embodiments, the cell support includes a third guide rod 4 arranged along a preset direction, and the second guide rods 101 of both clamping parts 1 are slidably connected to the third guide rod 4. Providing the third guide rod 4, so that the second guide rods 101 of both clamping parts 1 are slidably connected to it, further improves the stability and guidance of the movement of the clamping parts 1.

[0058] Simultaneously, when the locking member 103 is unlocked, operating the third guide rod 4 can move both second guide rods 101 at the same time, so as to adjust the distance between the two clamping blocks 102 of the clamping part 1. In order to prevent the third guide rod 4 from disengaging from the second guide rod 101, anti-disengagement blocks 401 are provided at both ends of the third guide rod 4.

[0059] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some exemplary embodiments, one clamping part 1 is provided with a slot 104 extending perpendicular to a preset direction, and another clamping part 1 is provided with an insert 105 adapted to the shape of the slot 104.

[0060] In this way, a slot 104 is provided in one clamping part 1 and an insert 105 is provided in the other. This structure facilitates the detachable connection between adjacent cell brackets. The connection method is simple and reliable, and can quickly realize the assembly and disassembly of multiple cell brackets, which is beneficial to the production and manufacturing of battery packs and subsequent maintenance.

[0061] The specific shape of the slot 104 can be, for example, T-shaped or trapezoidal, and the insert 105 can be adapted to the shape of the slot 104. Based on the clamping part 1 including two clamping blocks 102, slots 104 can be provided on both clamping blocks 102 on one clamping part 1, and inserts 105 can be provided on both clamping blocks 102 on the other clamping part 1.

[0062] It is worth noting that, regarding the cell support in this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still provided by... Figures 1 to 5 As shown, it may include, for example, two clamping parts 1 and an adjusting part 2 connected between the two clamping parts 1.

[0063] The clamping part 1 includes two clamping blocks 102, a second guide rod 101 is provided between the two clamping blocks 102, an extension section 1021 is provided on the clamping block 102, and a bolt is screwed onto the extension section 1021. After the bolt is tightened, the second guide rod 101 can be pressed onto the extension section 1021.

[0064] Among them, two opposing clamping blocks 102 on different clamping parts 1 are screwed together with screw rods 201. The ends of the screw rods 201 connected to the two clamping blocks 102 have opposite screw threads. The screw rods 201 are provided with cylindrical handles 202, and the handles 202 are provided with anti-slip knurling.

[0065] Among them, a first guide rod 301 is slidably connected between two opposing clamping blocks 102 on different clamping parts 1, and a third guide rod 4 is slidably connected between two second guide rods 101.

[0066] In the preferred embodiment of the battery cell bracket above, the specific configuration and arrangement of the clamping part 1 and the adjusting part 2, etc., can still be referred to the description in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the clamping part 1 and the adjusting part 2, etc., can also be referred to the description in the above exemplary embodiments.

[0067] The cell holder in this embodiment adopts the above design. By setting the adjustment part 2 and the clamping part 1, the clamping parts 1 of multiple cell holders can be detachably connected, enabling multiple holders to be connected in series. This allows the cell 5 to be arranged in a preset direction, adapting to the assembly requirements of battery packs of different capacities, which is beneficial to improving the versatility of the cell holder. At the same time, the adjustment part 2 has an adjustment capability, which can adjust the spacing of the clamping parts 1, so that two clamping parts 1 can clamp cell 5 of different sizes, further enhancing the adaptability of the cell holder to cell 5 of different specifications, which is beneficial to improving versatility.

[0068] An embodiment of the second aspect of this application provides a battery pack having a cell support provided in the embodiment of the first aspect of this application.

[0069] For example, the battery cell 5 can be a square battery cell, and a battery cell bracket can be set at each end of the length direction of the battery cell 5, so that adjacent battery cells 5 are connected by a structure of four sets of slots 104 and inserts 105, which helps to improve the connection stability between battery cells 5, and at the same time has a stronger ability to maintain the distance between adjacent battery cells 5.

[0070] The battery pack of this embodiment has the aforementioned cell support. By providing the adjustment part 2 and the clamping part 1, the clamping parts 1 of multiple cell supports can be detachably connected, enabling multiple supports to be connected in series. This allows the cells 5 to be arranged in a preset direction, adapting to the assembly requirements of different capacitance values ​​in the battery pack. This is beneficial to improving the versatility of the cell support and thus enhancing the flexibility of the cell 5 arrangement in the battery pack.

[0071] Meanwhile, the adjustment part 2 has the ability to adjust the spacing of the clamping parts 1, so that the two clamping parts 1 can clamp battery cells 5 of different sizes, further enhancing the adaptability of the battery cell bracket to battery cells 5 of different specifications, which is conducive to enriching the specifications of battery cells 5 that can be configured in the battery pack.

[0072] The above descriptions are merely some embodiments of this application and are not intended to limit this application.
