[0029] Please refer to Figure 1 and Figure 2This utility model provides a battery cell module 100, which includes a housing 10 and a plurality of battery cells 20 fixed within the housing 10. The housing 10 includes a support assembly. The support assembly is disposed at both ends of the battery cells 20. The support assembly includes a plurality of spaced-apart fixing brackets 11. A plurality of fixing parts 113 are provided on two adjacent fixing brackets 11. The fixing parts 113 are used to fix the ends of the battery cells 20.
[0030] Specifically, the battery cell 20 in this embodiment is a cylindrical battery cell 20. The support assembly is disposed on both sides of the end face of the cylindrical battery cell 20. It can be understood that the battery cells 20 in this embodiment are arranged in multiple rows, with two adjacent fixing brackets 11 used to fix one row of battery cells 20. In this embodiment, the housing 10 is a plastic part, meaning that all fixing brackets 11 are plastic parts. By dividing the support assembly into multiple fixing brackets 11, the size of a single plastic part is reduced, thereby reducing the mold opening cost of a single plastic part. Furthermore, when it is necessary to disassemble a single or part of the battery cells 20 inside the housing 10, only the fixing bracket 11 corresponding to the battery cell 20 needs to be disassembled, avoiding the complete disassembly of the entire support assembly, thus reducing the difficulty and cost of maintenance.
[0031] Furthermore, in this embodiment, at one end of the battery cell 20, the fixing bracket 11 includes two first brackets 111 and a second bracket 112. The second bracket 112 is disposed between the two first brackets 111. A fixing part 113 is provided on the side of the first bracket 111 facing the second bracket 112. A fixing part 113 is provided on both sides of the second bracket 112 facing the two first brackets 111.
[0032] It is understood that in this embodiment, the first bracket 111 is used to fix the two rows of battery cells 20 on the edge, and the second bracket 112 is used to fix the battery cell 20 located in the middle. The fixing portion 113 of the first bracket 111 facing the second bracket 112 is correspondingly arranged with the fixing portion 113 of the second bracket 112 facing the first bracket 111, for engaging and fixing the battery cell 20 located between the first bracket 111 and the second bracket 112. That is, the two fixing portions 113 facing each other are correspondingly arranged between two adjacent fixing brackets 11.
[0033] Specifically, in this embodiment, the battery cells 20 are arranged in three rows, and correspondingly, there are two first brackets 111 and two second brackets 112. The upper first bracket 111 and the upper second bracket 112 are used to fix the battery cells 20 in the first row. The upper second bracket 112 and the lower second bracket 112 are used to fix the battery cells 20 in the second row. The lower second bracket 112 and the lower first bracket 111 are used to fix the battery cells 20 in the third row. Of course, in other embodiments, the battery cells 20 can be arranged in two rows, with two first brackets 111 and one second bracket 112. The battery cells 20 can be arranged in four or five rows, etc., by increasing the number of second brackets 112 accordingly. The specific positional relationship is consistent with the arrangement of the upper three rows of battery cells 20, and will not be repeated here. This utility model does not limit the arrangement of the battery cells 20 or the number of second brackets 112.
[0034] Furthermore, on the second bracket 112, the fixing part 113 on one side is staggered with the fixing part 113 on the other side. It can be understood that, in this embodiment, the staggered arrangement of the adjacent rows of battery cells 20 can reduce the overall size of the battery cell module 100 and further reduce the mold opening cost of the housing 10 parts.
[0035] Specifically, in this embodiment, the fixing part 113 is a fixing groove. The shape of the fixing groove matches the side shape of the battery cell 20. It can be understood that in this embodiment, two fixing grooves arranged opposite each other between two adjacent fixing brackets 11 clamp a battery cell 20. Since the battery cell 20 in this embodiment is a cylindrical battery cell 20, the fixing groove is set as an arc-shaped groove. Of course, in other embodiments, when the battery cell 20 has other shapes, such as a square column, the fixing groove can be set as a "V" shaped groove or a square groove. This utility model does not limit the shape of the battery cell 20.
[0036] Please refer to Figure 3 In this embodiment, a baffle 114 is also provided on the fixing bracket 11. The baffle 114 is located at the fixing part 113 and is used to limit the position of the battery cell 20. It can be understood that in this embodiment, the shape of the fixing part 113 is consistent with the shape of the side of the battery cell 20. In order to prevent the battery cell 20 from falling off the fixing bracket 11, the baffle 114 is provided to abut against the end face of the battery cell 20.
[0037] Furthermore, in this embodiment, the end face of the battery cell 20 is provided with positive and negative tabs 21. A clearance hole 115 is provided on the baffle 114 to allow the electrodes of the battery cell 20 to pass. Specifically, in this embodiment, the clearance hole 115 is a semi-circular hole. It can be understood that between two adjacent fixing brackets 11, the two clearance holes 115 merge into a single circular hole to expose the tabs 21 on the end face of the battery cell 20, facilitating the operation of the battery cell module 100.
[0038] Please refer to Figure 2 In this embodiment, the housing 10 further includes two end caps 12. The two sides of the fixing bracket 11 are respectively fixedly connected to the end caps 12. It can be understood that the end caps 12 are located on both sides of the transverse arrangement direction of the battery cells 20. The end caps 12 are correspondingly arranged with the sides of the battery cells 20. The fixing bracket 11 is connected to the housing 10 by screws, adhesive, or other means; this utility model does not limit the connection method of the fixing bracket 11.
[0039] To improve the versatility of the end cover plate 12, in this embodiment, the battery cells 20 are arranged symmetrically, that is, the number of battery cells 20 in the first row and the third row are the same and are set accordingly, and the two ends of the battery cells 20 in the second row extend beyond the battery cells 20 in the first row or the battery cells 20 in the third row by the same distance, so that the end cover plate 12 can be replaced left and right or installed upside down.
[0040] Furthermore, to ensure a tight fit between the end cover plate 12 and the battery cell 20, the end cover plate 12 has a mating surface 121 on the side facing the battery cell 20 to mate with the battery cell 20. Specifically, in this embodiment, the battery cell 20 is arranged in three rows, wherein the number of battery cells 20 in the second row is greater than the number of battery cells 20 in the first or third row, that is, the two sides of the battery cell 20 are convex. Correspondingly, the mating surface 121 is set as a concave shape corresponding to the two sides of the three rows of battery cells 20.
[0041] The housing 10 also includes two side plates 13 located on the sides of the battery cells 20. The side plates 13 are connected to the end caps 12 and / or the mounting brackets 11. Specifically, the side plates 13 are located on both sides of the battery cells 20 in the vertical arrangement direction. The mounting brackets 11 are located on both sides of the battery cells 20 in the axial direction. The end caps 12 are located on both sides of the battery cells 20 in the transverse arrangement direction. It is understood that the end caps 12, the mounting brackets, and the side plates 13 are interconnected to form the housing 10, collectively enclosing the battery cells 20 within it.
[0042] Specifically, in this embodiment, the cells 20 are glued together with each other, between the cells 20 and the end cover plate 12, and between the cells 20 and the fixing bracket 11.
[0043] In this embodiment, the side plate 13 is an epoxy board to improve the insulation performance of the battery cell module 100.
[0044] The working principle and process of the battery cell module 100 in this embodiment of the utility model are as follows:
[0045] For example, first install one side of the fixing bracket 11, then sequentially install the battery cell 20 between the fixing parts 113 of the first bracket 111 and the second bracket 112, or between the fixing parts 113 of the two second brackets 112. The battery cell 20 is installed in place when it abuts against the baffle 114. Since the fixing parts 113 on both sides of the second bracket 112 are staggered, all the battery cells 20 are staggered after being positioned sequentially. Then, the battery cells 20 are fixed together with filler glue. Then install the other side of the fixing bracket 11. Simply slip the fixing bracket 11 onto the battery cells 20 sequentially. Install the end cover plate 12 on both sides of the battery cell 20, and then fix the side plate 13 to the end cover plate 12 and the fixing bracket 11. After installation, the battery cell 20 is located inside the housing 10, and the tab 21 at the end of the battery cell 20 is exposed through the clearance hole 115 of the fixing bracket 11.
[0046] It should be noted that the above installation sequence is only an example, and the installation sequence of the battery cell module 100 can be interchanged. This utility model only limits the positional relationship of the above-mentioned fixing bracket 11, end cover plate 12, side plate 13 and battery cell 20, and does not limit their installation sequence. Relevant technicians can operate according to specific needs.
[0047] When it is necessary to maintain the battery cell 20, if only one or part of the battery cell 20 needs to be removed, it is only necessary to remove or destroy the fixing bracket 11 corresponding to the battery cell 20 to be repaired.
[0048] The beneficial effects of the battery cell module 100 provided in this embodiment of the present invention include:
[0049] The battery cell module 100 of this utility model includes a housing 10 and a plurality of battery cells 20 fixed within the housing 10. The housing 10 includes a support assembly. The support assembly is disposed at both ends of the battery cells 20. The support assembly includes a plurality of spaced-apart fixing brackets 11. A plurality of fixing parts 113 are provided on two adjacent fixing brackets 11. The fixing parts 113 are used to fix the ends of the battery cells 20. By dividing the support assembly on one side of the housing 10 into a plurality of fixing brackets 11 and splicing them together, the volume of a single part on the housing 10 is reduced, thereby reducing the size of the mold for a single part, reducing the mold opening cost of the plastic part of the housing 10, and reducing the glue cost of a single part; when maintenance is required, only one or a portion of the fixing brackets 11 need to be disassembled, without having to completely dismantle and destroy the support assembly, thus reducing maintenance costs.
[0050] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
