Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a buffer spacer assembly, a battery device, and an electrical appliance. Background Technology

[0002] Battery devices are widely used in electronic devices such as mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and power tools, etc.

[0003] When assembling battery devices, it is necessary to install buffer spacers such as rubber on the individual battery cells to separate adjacent cells and buffer the expansion of the cells. Improving the universality of buffer spacers is a research direction in battery technology. Utility Model Content

[0004] This application provides a buffer spacer assembly, a battery device, and an electrical device that improves the versatility of the buffer spacer structure.

[0005] In a first aspect, embodiments of this application provide a buffer interval assembly, including a main frame and a thickness adjustment module. The main frame has a first surface and a second surface opposite to each other along its own thickness direction. The first surface is used to connect a battery cell. The main frame is provided with a first connecting portion, at least part of which is disposed on the second surface. The thickness adjustment module is located on the side where the second surface is located and has a second connecting portion. The thickness adjustment module can be connected to the main frame by docking the second connecting portion with the first connecting portion, and the first connecting portion and the second connecting portion are configured to be detachably connected.

[0006] By adopting the above technical solution, the buffer spacer assembly is designed to include a main frame and a thickness adjustment module. The main frame and the thickness adjustment module are detachably connected. The thickness of the buffer spacer assembly can be adjusted by removing or installing the thickness adjustment module on the main frame, thereby matching battery devices with different battery cell spacing requirements and improving the versatility of the buffer spacer assembly.

[0007] In some embodiments of this application, there are multiple thickness adjustment modules, which are stacked along a first direction. One of the thickness adjustment modules located on both sides is connected to the second surface. The first direction is the arrangement direction from the first surface to the second surface. The thickness adjustment modules have opposite third and fourth surfaces along the first direction. At least a portion of the second connecting part is disposed on the third surface. The thickness adjustment module has a third connecting part, at least a portion of which is disposed on the fourth surface. The third connecting part is adapted to the second connecting part. Two adjacent thickness adjustment modules are detachably connected through adjacent third and second connecting parts.

[0008] The above technical solution employs a multi-layered thickness adjustment module design, with detachable connections between adjacent thickness adjustment modules achieved through the second and third connecting parts. This makes thickness adjustment more flexible and efficient: users can add or remove modules layer by layer on the main frame as needed to quickly adjust the overall thickness of the buffer interval component without replacing the entire structure; at the same time, the standardized connection method between modules ensures structural stability and simplifies the disassembly and assembly process, significantly improving adjustment efficiency and ease of operation, and meeting the needs of different working conditions.

[0009] In some embodiments of this application, the second connecting part is inserted into, snapped into, or magnetically engaged with the first connecting part, and / or the second connecting part is inserted into, snapped into, or magnetically engaged with the third connecting part.

[0010] The above technical solutions offer advantages such as easy and quick alignment and installation with a stable structure through plug-in connection, simple operation without the need for additional fasteners through snap-fit ​​connection, and contactless automatic adsorption and positioning with support for quick assembly and disassembly. All three methods can improve the convenience of modular assembly.

[0011] In some embodiments of this application, the first connecting portion includes a first socket, the third connecting portion includes a second socket, and the second connecting portion includes a plug-in structure adapted to the first socket and the second socket respectively.

[0012] By adopting the above technical solution and using a combination of sockets and plug-in structures, rapid and accurate alignment and installation can be achieved, improving assembly efficiency. At the same time, this design facilitates standardized production, reduces manufacturing costs, and supports rapid disassembly and assembly and flexible combination of modules to meet different thickness adjustment requirements, thereby improving the maintainability and adaptability of the overall structure.

[0013] In some embodiments of this application, the thickness adjustment module includes an adjustment frame, which is provided with the third surface and the fourth surface.

[0014] By adopting the above technical solution, the thickness adjustment module is designed as an adjustment frame that matches the size and shape of the main frame. This allows the module to be more closely and seamlessly connected to the main frame, improving the overall structure and stability. At the same time, the unified shape facilitates standardized production and assembly, reduces manufacturing costs, and ensures that the thickness adjustment module is evenly stressed when it is superimposed on the main frame, reducing the possibility of local stress concentration, enhancing the durability of the entire component, and resulting in a neat and beautiful appearance.

[0015] In some embodiments of this application, the thickness adjustment module includes a connector, the adjustment frame has a third insertion hole on the third surface, a portion of the connector is inserted into the third insertion hole, and another portion of the connector is located outside the third insertion hole and forms the second connecting portion.

[0016] By adopting the above technical solution, the thickness adjustment module is designed to include a connector, and the connector is inserted into the third socket and exposed to form the second connection part. Compared with the method of directly machining the second connection part on the thickness adjustment module, the machining difficulty can be reduced. Moreover, the connector is small in size and light in weight, which makes it easy to install and disassemble, while saving material costs.

[0017] In some embodiments of this application, the buffer spacer assembly further includes a protective film, the first surface having an adhesive layer for connecting the battery cell, and the protective film removably covering the adhesive layer.

[0018] By adopting the above technical solution, the removable protective film can effectively reduce the possibility of the adhesive layer being contaminated or oxidized during transportation and assembly, and improve the reliability of the subsequent bonding of the adhesive layer to the battery cell; at the same time, the protective film is easy to peel off, the operation is simple, and it does not affect the assembly efficiency.

[0019] In some embodiments of this application, the main frame has a length direction and a width direction, and the length and width of the main frame are configured to be smaller than the length and width of the battery cell, respectively; along the length direction of the main frame, at least one end of opposite ends of the protective film is provided with a first positioning portion extending out of the main frame, the length of the first positioning portion being equal to half the difference between the length of the battery cell and the length of the main frame; along the width direction of the main frame, at least one side of opposite sides of the protective film is provided with a second positioning portion extending out of the main frame, the length of the second positioning portion being equal to half the difference between the width of the battery cell and the width of the main frame.

[0020] By adopting the above technical solution, the protective film is designed with a first positioning part and a second positioning part. The length of the first positioning part is equal to the difference between half the length of the battery cell and the length of the main frame, and the length of the second positioning part is equal to the difference between half the width of the battery cell and the width of the main frame. When connecting the main frame and the battery cell, the first positioning part and the second positioning part are aligned with the long side and the short side of the battery cell, respectively, so that the main frame can be quickly and accurately positioned in the center area of ​​the battery cell, reducing manual alignment errors and improving assembly efficiency. At the same time, it can make the buffer spacer component evenly stressed between two adjacent battery cells, improving structural stability and optimizing the overall performance of the battery module.

[0021] In some embodiments of this application, the first positioning part has a first positioning edge parallel to the length direction of the main frame, and / or the second positioning part has a second positioning edge parallel to the width direction of the main frame.

[0022] By adopting the above technical solution, a first positioning edge and a second positioning edge are set parallel to the length and width directions of the main frame, respectively. The first positioning edge and the second positioning edge can directly and accurately fit with the corresponding edge of the battery cell, realize rapid visual alignment, effectively reduce the possibility of installation offset of the buffer interval component, further simplify the positioning operation, and improve the accuracy and efficiency of assembly.

[0023] In some embodiments of this application, the protective film is a flexible element.

[0024] Using the above technical solution, the protective film is a flexible component, which makes it easy to use the protective film to position the main frame and then remove the protective film, thereby facilitating the subsequent connection of the adhesive layer to the battery cell.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0055] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0057] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0058] In this application, "multiple" means two or more (including two).

[0059] During the assembly of battery cells, a buffer spacer structure (such as a buffer pad) is usually installed between adjacent battery cells to separate them and buffer the expansion forces generated during charging and discharging. Buffer pads are typically made of rubber or other elastic materials, capable of absorbing volume changes in the battery cells and preventing direct contact between them, thereby reducing the risk of short circuits or mechanical damage.

[0060] However, existing buffer pads typically employ a fixed thickness design, making it difficult to adapt to the needs of different battery models or varying expansion characteristics, resulting in poor versatility. Furthermore, the thickness of existing buffer spacers is difficult to adjust after assembly, limiting their ability to cope with different operating conditions or variations in the expansion of individual battery cells.

[0061] Therefore, there is an urgent need for a buffer space structure with adjustable thickness and greater adaptability to improve its universality.

[0062] In view of this, this application provides a buffer interval component, which solves the above-mentioned technical problems by adding a removable thickness adjustment module to the main frame.

[0063] It should be noted that the battery cells described in the embodiments of this application are applicable to battery devices and electrical equipment using battery devices.

[0064] Electrical equipment can include vehicles, mobile phones, portable devices, laptops, ships, spacecraft, electric toys, and power tools, etc. Vehicles can be gasoline-powered cars, natural gas-powered cars, or new energy vehicles; new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. Spacecraft include airplanes, rockets, space shuttles, etc. Electric toys include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Power tools include metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers, etc. This application does not impose any special limitations on the above-mentioned electrical equipment.

[0065] For ease of explanation, the following embodiments use a vehicle as an example of electrical equipment.

[0066] Combined with appendix Figure 1 As shown in the illustration, this application provides an electrical device, which is a vehicle 1000. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery device 100 is installed inside the vehicle 1000, and 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 battery device 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during starting, navigation, and driving.

[0067] In some embodiments of this application, 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 fuel or natural gas to provide driving power for the vehicle 1000.

[0068] Combined with appendix Figure 2 As shown, this application provides a battery device, including a battery housing 10, a battery cell 20, and a buffer spacer assembly 30 described below.

[0069] The battery housing 10 provides a space for housing the battery cells 20, and the battery housing 10 can adopt various structures. In some embodiments, the battery housing 10 may include a first housing 1 and a second housing 2, which are mutually capped, and together define a space for housing the battery cells 20. Both the first housing 1 and the second housing 2 can be hollow structures with one open end, with the second housing 2 capping the open side of the first housing 1 so that the first housing 1 and the second housing 2 together define the space; alternatively, the second housing 2 can be a plate-like structure, and the first housing 1 can be a hollow structure with one open side, with the open side of the second housing 2 capping the open side of the first housing 1. Of course, the battery housing 10 formed by the first housing 1 and the second housing 2 can be of various shapes, such as a cylinder, a cuboid, etc.

[0070] The buffer spacing assembly 30 is installed inside the battery cell 20 and is located between two adjacent battery cells 20.

[0071] Combined with appendix Figure 3-5 As shown, this application embodiment provides a buffer interval assembly 30, including a main frame 31 and a thickness adjustment module 32. The main frame 31 has a first surface 311 and a second surface 312 opposite to its own thickness direction. The first surface 311 is used to connect the battery cell 20. The main frame 31 is provided with a first connecting part 313. The thickness adjustment module 32 is located on the side where the second surface 312 is located and has a second connecting part 321. The thickness adjustment module 32 can be connected to the main frame 31 through the docking of the first connecting part 313 and the second connecting part 321. The first connecting part 313 and the second connecting part 321 are configured to be detachably connected.

[0072] In this embodiment, the main frame 31 serves as a support structure for the buffer spacing assembly 30, and its first surface 311 is used to fix the battery cell 20. The main frame 31 can be supported by metal, plastic, or elastic materials. In some embodiments, the main frame 31 is made of elastic materials such as rubber, silicone rubber, or thermoplastic polyurethane. Elastic materials can absorb vibration and the deformation and expansion of the battery cell 20, reducing the possibility of damage to two adjacent battery cells 20 due to expansion.

[0073] In this embodiment, the second surface 312 of the main frame 31 is provided with a first connecting portion 313, which facilitates docking with the thickness adjustment module 32. In some embodiments, the interior of the main frame 31 may be designed with reinforcing ribs or cavities to balance weight and strength, and the edges of the main frame 31 may be processed into chamfers or sealed structures to assist in insulation and shock absorption.

[0074] In this embodiment, the thickness adjustment module 32 is detachably connected to the main frame 31 via the second connecting part 321. The material of the thickness adjustment module 32 and the main frame 31 can be the same or different. For example, the thickness adjustment module 32 can be made of metal, plastic, or elastic material (e.g., rubber). The number of thickness adjustment modules 32 can be one or multiple as described below.

[0075] The first connecting part 313 is located on the second surface 312 of the main frame 31, and the second connecting part 321 is provided on the thickness adjustment module 32. The two can be connected by means of plug-in, snap-fit, magnetic attraction or thread.

[0076] The buffer spacing component 30 is designed to include a main frame 31 and a thickness adjustment module 32. The main frame 31 and the thickness adjustment module 32 are detachably connected. When it is necessary to adjust the thickness of the buffer spacing component 30, the thickness of the buffer spacing component 30 can be adjusted by removing or installing the thickness adjustment module 32 on the main frame 31, thereby matching the battery device 100 with different battery cell 20 spacing requirements, and thus improving the versatility of the buffer spacing component 30.

[0077] Combined with appendix Figure 6 and 7 As shown, in some examples, optionally, there are multiple thickness adjustment modules 32, which are stacked along a first direction X. One of the thickness adjustment modules 32 located on both sides is connected to the second surface 312. The first direction X is the arrangement direction from the first surface 311 to the second surface 312. The thickness adjustment module 32 has opposite third surfaces 322 and fourth surfaces 323 along the first direction X. At least a portion of the second connecting portion 321 is disposed on the third surface 322. The thickness adjustment module 32 has a third connecting portion 324. At least a portion of the third connecting portion 324 is disposed on the fourth surface 323. The third connecting portion 324 is adapted to the second connecting portion 321. Two adjacent thickness adjustment modules 32 are detachably connected through adjacent third connecting portions 324 and second connecting portions 321.

[0078] The thickness adjustment module 32 is designed to be multiple, and the multiple thickness adjustment modules 32 adopt a multi-layer stacked design and are arranged sequentially along the thickness direction (first direction X) of the main frame 31. One of the thickness adjustment modules 32 located on both sides refers to the outermost thickness adjustment module 32 located in the stacked structure formed by the multiple thickness adjustment modules 32. This thickness adjustment module 32 is used to connect to the second surface 312, and the other outermost thickness adjustment module 32 is set away from the second surface 312.

[0079] Each thickness adjustment module 32 has a third surface 322 and a fourth surface 323 opposite to each other along its own thickness direction, wherein the third surface 322 is provided with a second connecting portion 321, and the fourth surface 323 is provided with a matching third connecting portion 324.

[0080] The second connecting part 321 and the third connecting part 324 between adjacent thickness adjustment modules 32 cooperate to achieve a detachable connection between the modules. The stacked thickness adjustment module 32 allows for flexible adjustment of the total thickness according to actual needs, and each module can be replaced or reassembled as an independent unit.

[0081] Taking the three thickness adjustment modules 32 in the figure as an example, the second connecting part 321 of the thickness adjustment module 32 closest to the main frame 31 is connected to the first connecting part 313 of the main frame 31. The third connecting part 324 of the thickness adjustment module 32 is used to connect to the second connecting part 321 of another thickness adjustment module 32. The second connecting part 321 of the thickness adjustment module 32 furthest from the main frame 31 is used to connect to the third connecting part 324 of the middle thickness adjustment module 32, thereby completing the stacked connection of the three thickness adjustment modules 32 on the main frame 31.

[0082] When it is necessary to adjust the thickness of the buffer interval component 30, this can be achieved by increasing or decreasing the number of thickness adjustment modules 32. This design expands the thickness adjustment range and is suitable for the height compensation requirements of battery cells 20 of different specifications.

[0083] As can be seen from the above description, this embodiment adopts a design of multiple thickness adjustment modules 32 stacked together, and realizes the detachable connection of two adjacent thickness adjustment modules 32 through the second connecting part 321 and the third connecting part 324, making the thickness adjustment more flexible and efficient: users can add or remove modules layer by layer on the main frame 31 according to their needs, and quickly adjust the overall thickness of the buffer interval component 30 without replacing the overall structure; at the same time, the standardized connection method between modules not only ensures the structural stability, but also simplifies the disassembly and assembly process, significantly improving the adjustment efficiency and ease of operation, and meeting the needs of different working conditions.

[0084] In some examples, the second connecting portion 321 may optionally be engaged with the first connecting portion 313 by insertion, snap-fit, or magnetic attraction, and / or the second connecting portion 321 may be engaged with the third connecting portion 324 by insertion, snap-fit, or magnetic attraction.

[0085] The above embodiments indicate that the second connecting part 321 can be connected to the first connecting part 313 and the third connecting part 324 by means of plug-in engagement, snap-in engagement or magnetic engagement.

[0086] Among them, the plug-in mating can adopt the structure of plug-in hole and plug-in structure 3211 to achieve rapid alignment and installation. The mating has the advantages of accurate positioning, strong shear resistance, and convenient disassembly and assembly.

[0087] In some embodiments, the first connecting portion 313 may be designed to include a socket (e.g., the first socket 3131 described below), and the second connecting portion 321 may be designed to include a plug-in structure 3211. When the first connecting portion 313 includes a socket and the second connecting portion 321 includes a plug-in structure 3211, the third connecting portion 324 may also include a socket (e.g., the second socket 3241 described below), and the socket may be a blind hole structure.

[0088] Alternatively, the second connecting part 321 can be designed to include a socket, and the first connecting part 313 can be designed to include a plug structure 3211 (e.g., a plug). This embodiment is not shown in the figure.

[0089] In addition, the second connecting part 321 and the third connecting part 324 need to be designed to be arranged in opposite directions along the thickness direction of the thickness adjustment module 32, so that the thickness adjustment module 32 can be easily connected to the main frame 31 and other thickness adjustment modules 32, thus realizing the design of the thickness adjustment module 32 as a standard part.

[0090] The snap-fit ​​connection is achieved through the engagement of elastic buckles and slots (this embodiment is not shown in the figure). In some embodiments, both the first connecting part 313 and the third connecting part 324 may include elastic buckles, and the second connecting part 321 may include a slot, or vice versa. The snap-fit ​​connection has a self-locking function and is not easily loosened under vibration, thus improving the connection stability between the main frame 31 and the thickness adjustment module 32, and also improving the connection stability between two adjacent thickness adjustment modules 32.

[0091] Magnetic attraction refers to the connection between two parts using the attraction of a magnetic structure (not shown in the figure). For example, a magnetic structure can be provided on the second surface 312 of the main frame 31, and magnetic structures can be provided on the third surface 322 and the fourth surface 323 of the thickness adjustment module 32, or the materials of the main frame 31 and the thickness adjustment module 32 can be designed to include magnetic materials.

[0092] As can be seen from the above description, this embodiment uses plug-in, snap-in, or magnetic connection to connect the second connecting part 321 to the first connecting part 313 and the third connecting part 324 respectively. Plug-in connection facilitates quick alignment and installation and has a stable structure. Snap-in connection is easy to operate and does not require additional fasteners. Magnetic connection can achieve contactless automatic adsorption and positioning and supports quick disassembly and assembly. All three methods can improve the convenience of modular assembly.

[0093] Of course, in addition to the methods mentioned above, the connecting part can also adopt threaded fastening, hook and loop fasteners (Vessel fasteners), or interference fit, etc. This embodiment will not list them all.

[0094] Combined with appendix Figure 4 and attached Figure 5 As shown, in some examples, optionally, the first connecting portion 313 includes a first socket 3131, the third connecting portion 324 includes a second socket 3241, and the second connecting portion 321 includes a plug-in structure 3211 adapted to the first socket 3131 and the second socket 3241 respectively.

[0095] The first socket 3131 can be a blind hole, and the plug-in connector can be cylindrical, block-shaped, or other shapes. The size and shape of the plug-in structure 3211 are matched with the first socket 3131 and the second socket 3241, respectively, so that the plug-in structure 3211 can be directly inserted into the first socket 3131 or the second socket 3241.

[0096] The plug-in structure 3211 can be a fixed connection (e.g., welding) or a structure integrally formed on the thickness adjustment module 32, or it can be a separate plug-in component 326 as described below.

[0097] The number of first sockets 3131, second sockets 3241, and plug-in structures 3211 can be one or more. Multiple plug-in structures 3211 connected to multiple first sockets 3131 one-to-one can improve the stability of the connection between the main frame 31 and the thickness adjustment module 32. Similarly, multiple plug-in structures 3211 connected to multiple second sockets 3241 one-to-one can improve the stability of the connection between two adjacent thickness adjustment modules 32.

[0098] This embodiment uses a combination of sockets and plug-in structure 3211 to achieve rapid and accurate alignment and installation, improving assembly efficiency. At the same time, the sockets and plug-in structure 3211 facilitate standardized production, reduce manufacturing costs, and support rapid disassembly and assembly and flexible combination of modules to meet different thickness adjustment requirements, thereby improving the maintainability and adaptability of the overall structure.

[0099] Combined again with the appendix Figure 5 As shown, in some examples, the thickness adjustment module 32 optionally includes an adjustment frame 325, which has a third surface 322 and a fourth surface 323.

[0100] Both the adjustment frame 325 and the main frame 31 mentioned above can be rectangular frames, or they can be triangular frames, polygonal frames, circular frames, etc. This embodiment will not list them one by one.

[0101] The adjustment frame 325 is matched with the main frame 31, and the two have the same or basically the same shape and size. For example, the length difference between the adjustment frame 325 and the main frame 31 is no more than 10mm, and the width difference is no more than 10mm.

[0102] Designing the thickness adjustment module 32 as an adjustment frame 325 that matches the size and shape of the main frame 31 allows the module to be more closely and seamlessly connected to the main frame 31, improving the overall structure and stability. At the same time, the unified shape facilitates standardized production and assembly, reduces manufacturing costs, and ensures that the thickness adjustment module 32 and the main frame 31 are stacked evenly, reducing the possibility of local stress concentration, enhancing the durability of the entire component, and resulting in a neat and beautiful appearance.

[0103] Combined with appendix Figure 8 As shown, in some examples, optionally, the thickness adjustment module 32 includes a connector 326, the adjustment frame 325 has a third socket 3221 on the third surface 322, a portion of the connector 326 is inserted into the third socket 3221, and another portion of the connector 326 is located outside the third socket 3221 and forms a second connection portion 321.

[0104] The connector 326 can be columnar, block-shaped, or other structures. When the connector 326 is inserted into the third socket 3221 of the adjusting frame 325, part of the connector 326 is exposed to form the aforementioned connector structure 3211.

[0105] When it is necessary to adjust the thickness of the buffer interval assembly 30, the connector 326 and the adjustment module can be selectively added. Alternatively, the buffer interval assembly 30 may only have the main frame 31 and the connector 326, without the adjustment frame 325, thereby further reducing the thickness of the buffer interval assembly 30.

[0106] The thickness adjustment module 32 is designed to include a connector 326, with the connector 326 partially inserted into the third socket 3221 and exposed to form the second connection part 321. Compared with the method of directly machining the second connection part 321 on the thickness adjustment module 32, the machining difficulty can be reduced. Moreover, the connector 326 is small in size and light in weight, making it easy to install and disassemble, while saving material costs.

[0107] Combined with appendix Figure 3 Appendix Figure 6 and appendix Figure 9 As shown, in some examples, the buffer spacing assembly 30 may optionally include a protective film 33, the first surface 311 of which is provided with an adhesive layer for connecting the battery cell 20, the protective film 33 being removably covered by the adhesive layer.

[0108] The protective film 33 can be made of materials such as PE (polyethylene) release film or PET (polyester) release film. PE release film has good flexibility and is suitable for curved surface bonding, while PET release film has higher temperature resistance and tear resistance.

[0109] Before installing the buffer spacer assembly 30, the operator needs to remove the protective film 33 to expose the adhesive layer so that it can adhere to the surface of the battery cell 20.

[0110] The removable protective film 33 can effectively reduce the possibility of the adhesive layer being contaminated or oxidized during transportation and assembly, and improve the reliability of the subsequent bonding of the adhesive layer to the battery cell 20; at the same time, the protective film 33 is easy to peel off, the operation is simple, and it does not affect the assembly efficiency.

[0111] In some examples, optionally, the main frame 31 has a length direction and a width direction, the length and width of the main frame 31 being configured to be smaller than the length and width of the battery cell 20, respectively; along the length direction of the main frame 31, at least one of the opposite ends of the protective film 33 is provided with a first positioning portion 331 extending out of the main frame 31, the length of the first positioning portion 331 being equal to half the difference between the length of the battery cell 20 and the length of the main frame 31; along the width direction of the main frame 31, at least one of the opposite sides of the protective film 33 is provided with a second positioning portion 332 extending out of the main frame 31, the length of the second positioning portion 332 being equal to half the difference between the width of the battery cell 20 and the width of the main frame 31.

[0112] The main frame 31 is designed to be smaller than the battery cell 20 in both length and width, which can save materials and reduce costs.

[0113] The protective film 33 extends into a first positioning portion 331 and a second positioning portion 332. The length of the first positioning portion 331 is precisely matched to half the difference between the length of the battery cell 20 and the length of the main frame 31, and the length of the second positioning portion 332 is also matched to half the difference between the width of the battery cell 20 and the width of the main frame 31. This design allows the protective film 33 to not only protect the adhesive layer but also serve a positioning function.

[0114] During installation, the operator only needs to align the first positioning part 331 of the protective film 33 with the long side of the battery cell 20 and the second positioning part 332 with the short side of the battery cell 20 to make the main frame 31 automatically centered.

[0115] This mechanical alignment method significantly reduces the risk of errors caused by manual intervention, improves assembly efficiency, and allows the buffer spacing component 30 to be evenly stressed between two adjacent battery cells 20, thereby improving structural stability and optimizing the overall performance of the battery module.

[0116] In some examples, the first positioning part 331 may optionally have a first positioning edge 3311 parallel to the length direction of the main frame 31, and / or the second positioning part 332 may have a second positioning edge 3321 parallel to the width direction of the main frame 31.

[0117] The first positioning part 331 has a first positioning edge 3311 parallel to the length direction of the main frame 31, and the second positioning part 332 has a second positioning edge 3321 parallel to the width direction of the main frame 31. These two sets of edges form a standard right-angled reference plane, which can directly and closely fit with the corresponding long and short sides of the battery cell 20. This structure upgrades the positioning function from simple size matching to geometric reference alignment, achieving dual positioning protection.

[0118] A first positioning edge 3311 and a second positioning edge 3321 are respectively set parallel to the length and width directions of the main frame 31. The first positioning edge 3311 and the second positioning edge 3321 can directly and accurately fit with the corresponding edge of the battery cell 20, realize rapid visual alignment, effectively reduce the possibility of installation offset of the buffer interval assembly 30, further simplify the positioning operation, and improve the accuracy and efficiency of assembly.

[0119] In some examples, the protective film 33 is optionally a flexible element.

[0120] Flexible components refer to thin-film materials with a certain degree of bending flexibility and deformability, which can conform to the surface of the main frame 31 and adapt to its contour changes. This flexible characteristic allows it to protect the adhesive layer without affecting the structural rigidity of the main frame 31, and can compensate for minor assembly errors through deformation during installation.

[0121] The flexible component can be polyethylene (PE) release film, polyester (PET) release film, polypropylene (PP) release film, etc., which will not be listed one by one in this embodiment.

[0122] The protective film 33 is a flexible component, making it easier to remove from the adhesive layer and reducing residue or damage to the adhesive layer. Furthermore, the flexible nature of the component allows the installation of the main frame 31 to be similar to the process of applying a screen protector to a mobile phone; for example, first... Figure 6 Align the first positioning edge 3311 and the second positioning edge 3321 with the edge of the battery cell 20. Then, first peel off the part of the first positioning edge 3311 and the second positioning edge 3321 that is away from the protective film, and stick the corresponding adhesive layer to the battery cell 20. Then peel off and press to stick. Finally, peel off the first positioning part 331 and the second positioning part 332 to achieve tool-free and precise installation.
