Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field of new energy storage equipment, and in particular to a splicing cell bracket, bracket splicing body, cell module and battery pack. Background Technology
[0002] In battery cell modules, as the number of individual battery cells changes, the model of the battery cell bracket also needs to be adjusted and adapted. To improve the adaptability of the battery cell bracket, a universal cylindrical battery cell splicing bracket is disclosed in Chinese patent document CN218887364U. It achieves concave-convex splicing combination between multiple brackets through connectors. However, due to the structural design of the connectors, adjacent brackets can be easily disassembled, making it difficult for the bracket to adapt to working conditions such as drops, vibrations, and bumps. Utility Model Content
[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a splicing cell bracket, bracket splicing body, cell module and battery pack with reliable and stable splicing and higher structural strength.
[0004] The purpose of this disclosure is achieved through the following technical solution:
[0005] A splicing battery cell bracket includes a bracket body, on which a first splicing structure and a second splicing structure are provided. The first splicing structure is used to engage with the second splicing structure on another bracket body, so that two adjacent bracket bodies can be detachably spliced.
[0006] The splicing-type battery cell support also includes a mating structure;
[0007] The mating structure is fixedly mounted on the bracket body;
[0008] When two adjacent support bodies are detachably spliced, the mating structure is coaxially opposite to the mating structure on the other support body, and the mating structure and the mating structure on the other support body are locked together.
[0009] In some embodiments, the number of the mating structures is at least two, including at least one first mating structure and at least one second mating structure; when two adjacent bracket bodies are detachably spliced, each of the first mating structures is respectively used to be coaxially opposite to the corresponding second mating structure on the other bracket body, and connected to each other through a first locking member.
[0010] In some embodiments, the first locking member is mounted on the first mating structure, and the first mating structure is locked to a second mating structure on another bracket body by the first locking member.
[0011] In some embodiments, the second mating structure has a threaded locking hole, the wall of which is used to thread into the first locking member on the first mating structure on another bracket body.
[0012] In some embodiments, the first locking element is a screw, bolt, nut, or latch.
[0013] In some embodiments, the support body has a splicing surface, and the first splicing structure and the second splicing structure are both disposed on the splicing surface. The mating structure protrudes from one side of the splicing surface. A clearance recess is formed on the other side of the splicing surface, and the clearance recess is coaxially opposite to the mating structure. When the splicing surfaces of two adjacent support bodies are fitted together, the clearance recess of one support body is used to partially mate with the mating structure of the other support body.
[0014] In some embodiments, the mating structure on the support body is used to abut against the mating structure on another support body to form a support column structure when two adjacent support bodies are detachably spliced together.
[0015] A bracket assembly includes at least two spliced cell brackets according to any of the above embodiments; between two adjacent bracket bodies, a first splicing structure on one bracket body is concave-convexly fitted to a second splicing structure on the other bracket body, and a mating structure on one bracket body is locked to a mating structure on the other bracket body.
[0016] A battery cell module includes at least two individual battery cells and a spliced battery cell bracket according to any of the above embodiments; at least two of the individual battery cells are arranged and installed in the bracket body, and at least two of the individual battery cells are electrically connected sequentially in the arrangement direction.
[0017] A battery pack includes a housing and a cell module according to any of the above embodiments, wherein the cell module is disposed within the housing.
[0018] Compared with the prior art, this disclosure has at least the following advantages:
[0019] The aforementioned modular battery cell support structure features a first and a second splicing structure on its main body. Between two adjacent support bodies, the first splicing structure on one support body can engage with the second splicing structure on the other, enabling detachable splicing between the two support bodies. Furthermore, because the support body has a fixed mating structure, when two adjacent support bodies are detachably spliced, the mating structure on one support body can be coaxially aligned with the mating structure on the other support body. By locking these mating structures together, the connection between the two adjacent support bodies becomes more secure, reducing the likelihood of accidental disassembly under conditions such as drops, vibrations, or bumps.

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.
[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0033] Please see Figure 1 and Figure 2 One embodiment of the modular battery cell support 10 includes a support body 100 and a mating structure. The support body 100 is provided with a first splicing structure 111 and a second splicing structure 112. The first splicing structure 111 is used to engage with the second splicing structure 112 on another support body 100, allowing adjacent support bodies 100 to be detachably spliced. The mating structure is fixedly disposed on the support body 100. When adjacent support bodies 100 are detachably spliced, the mating structure is coaxially opposite to the mating structure on the other support body 100, and the mating structure and the mating structure on the other support body 100 are locked together. In this embodiment, the second splicing structure 112 is a protrusion, and the first splicing structure 111 is a latch; the protrusion and the latch engage in a tight, interlocking fit.
[0034] It is understandable that, since the support body 100 is provided with a first splicing structure 111 and a second splicing structure 112, between two adjacent support bodies 100, the first splicing structure 111 on one support body 100 can engage with the second splicing structure 112 on the other support body 100, thus enabling detachable splicing between the two adjacent support bodies 100. Furthermore, because the support body 100 is fixedly provided with a mating structure, when two adjacent support bodies 100 are detachably spliced, the mating structure on one support body 100 can be coaxially aligned with the mating structure on the other support body 100. By locking the mating structure on one support body 100 to the mating structure on the other support body 100 together, the connection between the two adjacent support bodies 100 becomes more secure, reducing the possibility of accidental disassembly between the two support bodies 100 under conditions such as drops, vibrations, and bumps.
[0035] Please see Figure 1 and Figure 2 In some embodiments, the number of mating structures is at least two, including at least one first mating structure 1111 and at least one second mating structure 1211. When two adjacent support bodies 100 are detachably spliced, each first mating structure 1111 is coaxially opposite to the corresponding second mating structure 1211 on the other support body 100, and is interconnected by a first locking member 1113. It can be understood that by having each first mating structure 1111 on one support body 100 coaxially opposite to the corresponding second mating structure 1211 on the other support body 100, and then connecting each first mating structure 1111 on one support body 100 to the corresponding first mating structure 1111 on the other support body 100 via the first locking member 1113, more than two connection points can be formed between the two adjacent support bodies 100, further enhancing the connection strength between them.
[0036] Please see Figure 2 In some embodiments, a first locking member 1113 is mounted on a first mating structure 1111, and the first mating structure 1111 is locked to a second mating structure 1211 on another bracket body 100 by the first locking member 1113. It can be understood that, in two adjacent bracket bodies 100, by locking the first locking member 1113 mounted on the first mating structure 1111 of one bracket body 100 to the second mating structure 1211 on the other bracket body 100, the connection strength between the two adjacent bracket bodies 100 can be flexibly changed by adjusting the first locking member 1113.
[0037] Please see Figure 2In some embodiments, the second mating structure 1211 has a threaded locking hole 1201, the wall of which is used to thread-fit with the first locking member 1113 on the first mating structure 1111 of another bracket body 100. It can be understood that, in two adjacent bracket bodies 100, by having the first locking member 1113 on the first mating structure 1111 of one bracket body 100 partially pass through the threaded locking hole 1201 on the second mating structure 1211 of the other bracket body 100 and thread-fit with the wall of the threaded locking hole 1201, the connection strength between the two adjacent bracket bodies 100 can be flexibly changed by twisting the first locking member 1113.
[0038] In some embodiments, the second mating structure 1211 is provided with a second locking member, which is used to lock into a first locking member 1113 on the first mating structure 1111 on another bracket body 100. It can be understood that by locking the first locking member 1113 on the first mating structure 1111 of one bracket body 100 to the second locking member on the second mating structure 1211 of the other bracket body 100, the connection strength between two adjacent bracket bodies 100 can be flexibly changed by adjusting either the first locking member 1113 or the second locking member.
[0039] The locking connection between the first locking member 1113 and the second mating structure 1211 can be implemented in the following ways:
[0040] In some embodiments, the first locking member 1113 is a screw. Specifically, in two adjacent bracket bodies 100, the first locking member 1113 is a screw, and the second locking member is a threaded sleeve. By locking the screw in the threaded hole of the threaded sleeve, each first mating structure 1111 on one bracket body 100 can be fastened to the corresponding second mating structure 1211 on the other bracket body 100. Please refer to [link / reference]. Figure 2 Alternatively, the screws installed on the first mating structures 1111 on one bracket body 100 can be directly locked into the threaded locking holes 1201 on the corresponding second mating structure 1211 on the other bracket body 100.
[0041] In some embodiments, the first locking member 1113 is a screw. Specifically, in two adjacent bracket bodies 100, the screws installed on the first mating structures 1111 on one bracket body 100 are directly locked into the screw holes opened on the corresponding second mating structures 1211 on the other bracket body 100. Alternatively, the first locking member 1113 can be a screw, and the second locking member can be a mating member. By locking the screws into the screw holes of the mating members, the first mating structures 1111 on one bracket body 100 can be fastened together with the corresponding second mating structures 1211 on the other bracket body 100.
[0042] In other embodiments, the first locking member 1113 is a bolt. Specifically, in two adjacent bracket bodies 100, the bolts installed on each of the first mating structures 1111 on one bracket body 100 are directly locked into the threaded holes opened in the corresponding second mating structures 1211 on the other bracket body 100. Alternatively, the first locking member 1113 can be a bolt, and the second locking member can be a nut. By making the bolt and nut threadedly engaged, each of the first mating structures 1111 on one bracket body 100 can be fastened together with the corresponding second mating structures 1211 on the other bracket body 100.
[0043] In some embodiments, the first locking element 1113 is a nut. Specifically, in two adjacent bracket bodies 100, the nuts installed on the first mating structures 1111 on one bracket body 100 are directly locked onto the threaded ends formed on the corresponding second mating structures 1211 on the other bracket body 100. Alternatively, the first locking element 1113 can be a nut, and the second locking element can be a bolt. By making the nut and bolt threadedly engage, the first mating structures 1111 on one bracket body 100 can be fastened together with the corresponding second mating structures 1211 on the other bracket body 100.
[0044] In some embodiments, the first locking member 1113 is a latch. Specifically, in two adjacent support bodies 100, the latches installed on the first mating structures 1111 on one support body 100 are directly locked and fastened to the corresponding latching positions formed on the second mating structures 1211 on the other support body 100. Alternatively, the first locking member 1113 can be a latch, and the second locking member can be a mating fastener. By locking the latch and the mating fastener together, the first mating structures 1111 on one support body 100 can be fastened together with the corresponding second mating structures 1211 on the other support body 100.
[0045] Please see Figure 1 and Figure 2In some embodiments, the support body 100 has a splicing surface, and both the first splicing structure 111 and the second splicing structure 112 are disposed on the splicing surface. A mating structure protrudes from one side of the splicing surface. A clearance recess 1112 is formed on the other side of the splicing surface, and the clearance recess 1112 is coaxially opposite to the mating structure. When the splicing surfaces of two adjacent support bodies 100 are fitted together, the clearance recess 1112 of one support body 100 is used to partially mate with the mating structure of the other support body 100. It can be understood that since both the first splicing structure 111 and the second splicing structure 112 are disposed on the splicing surface, when the splicing surfaces of two adjacent support bodies 100 are fitted together, by having the first splicing structure 111 on one support body 100 mate with the second splicing structure 112 on the other support body 100, the two adjacent support bodies 100 can be detachably spliced. Furthermore, since the clearance recess 1112 and the mating structure are coaxially opposite each other, when the clearance recess 1112 of one support body 100 partially mates with the mating structure of another support body 100, the mating structure on one support body 100 can be coaxially opposite to the mating structure of the other support body 100. Moreover, by locking the mating structure on one support body 100 to the mating structure of the other support body 100 together, the two adjacent support bodies 100 can be more securely connected.
[0046] Please see Figure 1 and Figure 2 In this embodiment, the support body 100 includes an upper frame 110 and a lower frame 120. The upper frame 110 and the lower frame 120 are positioned opposite each other and are interlocked. The upper frame 110 has an upper splicing portion 1110, and the lower frame 120 has a lower splicing portion 1210. The upper splicing portion 1110 and the lower splicing portion 1210 form a splicing surface. Both the upper splicing portion 1110 and the lower splicing portion 1210 have protruding mating structures. Both the upper splicing portion 1110 and the lower splicing portion 1210 have clearance recesses 1112. Each mating structure is positioned opposite to the corresponding clearance recess 1112.
[0047] Please see Figure 2In some embodiments, the mating structure on the support body 100 is used to abut against the mating structure on another support body 100 to form a supporting column structure when the two adjacent support bodies 100 are detachably spliced. It can be understood that when the two adjacent support bodies 100 are detachably spliced, by making the mating structure on one support body 100 abut against the mating structure on the other support body 100, the mating structure on one support body 100 and the mating structure on the other support body 100 can form a supporting column structure, thereby simultaneously improving the strength of the frame structure after the two adjacent support bodies 100 are connected, thus better installing the battery cell 20. In this embodiment, both the first mating structure 1111 and the second mating structure 1211 are columnar, but this is not limited here; those skilled in the art can also set the first mating structure 1111 and the second mating structure 1211 into other shapes as needed.
[0048] Please see Figure 1 and Figure 2 This disclosure also provides a bracket assembly, including at least two spliced cell brackets 10 according to any of the above embodiments; between two adjacent bracket bodies 100, a first splicing structure 111 on one bracket body 100 is engaged with a second splicing structure 112 on the other bracket body 100, and a mating structure on one bracket body 100 is locked to a mating structure on the other bracket body 100. It can be understood that when two adjacent bracket bodies 100 are detachably spliced, the mating structure on one bracket body 100 can be coaxially opposite to the mating structure on the other bracket body 100, and by locking the mating structure on one bracket body 100 to the mating structure on the other bracket body 100 together, the connection between the two adjacent bracket bodies 100 can be made more secure, reducing the possibility of accidental disassembly between the two bracket bodies 100 under conditions such as drops, vibrations, and bumps.
[0049] Please see Figure 2 and Figure 3 This disclosure also provides a battery cell module, including at least two individual battery cells 20 and a spliced battery cell bracket 10 of any of the above embodiments; the at least two individual battery cells 20 are arranged and installed within the bracket body 100, and the at least two individual battery cells 20 are sequentially electrically connected in the arrangement direction. It can be understood that by arranging and installing at least two individual battery cells 20 within the bracket body 100, and sequentially electrically connecting the at least two individual battery cells 20 in the arrangement direction, the at least two individual battery cells 20 can be connected in series or parallel to form a circuit to supply power to the outside.
[0050] This disclosure also provides a battery pack, including a housing and a cell module from any of the above embodiments, wherein the cell module is disposed within the housing. It is understood that by disposing of the cell module within the housing, a battery pack with stable power supply can be formed, thereby better adapting to operating conditions such as drops, vibrations, and bumps.
[0051] Compared with the prior art, this disclosure has at least the following advantages:
[0052] The aforementioned splicing cell support 10, because the support body 100 is provided with a first splicing structure 111 and a second splicing structure 112, allows for detachable splicing between adjacent support bodies 100. The first splicing structure 111 on one support body 100 can engage with the second splicing structure 112 on the other support body 100. Furthermore, because the support body 100 is fixedly provided with a mating structure, when adjacent support bodies 100 are detachably spliced, the mating structure on one support body 100 can be coaxially aligned with the mating structure on the other support body 100. By locking the mating structure on one support body 100 to the mating structure on the other support body 100 together, the connection between adjacent support bodies 100 becomes more secure, reducing the possibility of accidental disassembly under conditions such as drops, vibrations, and bumps.
[0053] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
