[0002] In related technologies, multiple cells in a battery module are typically positioned using a plastic bracket to maintain spacing and insulation between rows of cells. The plastic bracket usually has a concave surface that fits the outer circumference of the cell.

Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the 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. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0039] This application provides a cell positioning frame, a support assembly, and a battery module. These will be described in detail below.

[0040] Figure 1 This is a perspective view of one embodiment of the battery module provided in this application. Figure 1As shown, the battery module 1 includes a battery assembly 10, which includes multiple rows of battery cells 11 arranged at intervals. Multiple cells 11 in each row are arranged at intervals in the arrangement direction.

[0041] The battery module 1 also includes a foam 20, which wraps at least a portion of the battery assembly 10 to position and protect the multiple cells 11 of the battery assembly 10.

[0042] In addition, such as Figure 2 As shown, the battery module 1 also includes a support assembly 30. The support assembly 30 is positioned between adjacent rows of battery cells 11 to allow for the positioning of multiple battery cells 11 within the battery module 10. Figures 2 to 4 As shown, the bracket assembly 30 includes a cell positioning frame 31, which includes a positioning plate 311. The positioning plate 311 includes plate surfaces 3111 located on both sides of its thickness direction Y. The plate surface 3111 includes a plurality of first concave surfaces 3112 arranged along the length direction X of the positioning plate 311. The first concave surfaces 3112 are adapted to the outer peripheral surface 111 of the cell 11.

[0043] Therefore, when the bracket assembly 30 is positioned between two adjacent rows of battery cells 11, the two side plates 3111 of the positioning plate 311 of the battery cell positioning frame 31 are adapted to the outer peripheral surface 111 of the corresponding battery cell 11 through the first concave surface 3112, so as to position the relative position between the two adjacent rows of battery cells 11, making the position of the two adjacent rows of battery cells 11 more stable. Moreover, by adapting the multiple first concave surfaces 3112 of the same side plate 3111 of the positioning plate 311 to the outer peripheral surface 111 of multiple battery cells 11 in the same row of battery cells 11, multiple battery cells 11 in the same row of battery cells 11 can be positioned, so that the relative position of multiple battery cells 11 in the same row of battery cells 11 remains stable.

[0044] It should be noted that the first concave surface 3112 is adapted to the outer peripheral surface 111 of the battery cell 11, meaning that the shape of the first concave surface 3112 is the same as or similar to the shape of the outer peripheral surface 111 of the battery cell 11, so that the first concave surface 3112 and the outer peripheral surface 111 of the battery cell 11 cooperate with each other for positioning. For example, when the battery cell 11 is a cylindrical battery cell, the first concave surface 3112 and the outer peripheral surface 111 of the battery cell 11 have similar or identical arc surfaces.

[0045] In some embodiments, the multiple first concave surfaces 3112 on both sides of the positioning plate 311 can be staggered, thereby causing the adjacent rows of cells 11 on both sides of the positioning plate 311 to be staggered, which is beneficial to improve the compactness of the arrangement of the adjacent rows of cells 11 and reduce the gap width W between the adjacent rows of cells 11.

[0046] In some embodiments, the expanding foam 20 may be used to wrap at least a portion of the bracket assembly 30 to keep the relative positions of the bracket assembly 30 and the battery cell 11 stable, which is beneficial to improving the connection stability between the bracket assembly 30 and the battery cell 11.

[0047] Specifically, the same end of a plurality of cells 11 of the battery assembly 10 extends out of the same side of the expanding foam 20, so that the expanding foam 20 encloses a portion of the plurality of cells 11 of the battery assembly 10. The cell positioning frame 31 of the support assembly 30 is located within the expanding foam 20, so that the expanding foam 20 encloses the cell positioning frame 31.

[0048] In some embodiments, such as Figures 5 to 8 As shown, the cell positioning frame 31 also includes a first wiring section 312, which is located on one side of the positioning plate 311 in the width direction Z, and forms a first wiring channel 3121 extending along the length direction X of the positioning plate 311. Therefore, the wiring harness 42 connected to the temperature probe 41 can be installed in the first wiring channel 3121, allowing the wiring harness 42 to extend along the length direction X of the positioning plate 311 between adjacent rows of cells 11. The installation of the wiring harness 42 is more stable and convenient, unaffected by interference from the cells 11, which helps improve the assembly efficiency of the battery module 1.

[0049] It should be noted that the first wiring channel 3121 can be a channel defined by the wiring structure 3122, or the first wiring channel 3121 can be a slot, a through hole or other space that can accommodate the wire harness 42.

[0050] The first wiring section 312 may include multiple wiring structures 3122 protruding from one side of the positioning plate 311 in the width direction Z, and these multiple wiring structures 3122 are arranged along the length direction X of the positioning plate 311. The multiple wiring structures 3122 form a first wiring channel 3121. Therefore, while ensuring that the first wiring channel 3121 provides a better limiting effect on the wire harness 42, the material used in the first wiring section 312 can be reduced, which helps to reduce the weight and cost of the cell positioning frame 31.

[0051] In some embodiments, the wiring structure 3122 may include at least two limiting protrusions 3123 protruding from one side of the positioning plate 311 in the width direction Z. The at least two limiting protrusions 3123 are distributed on both sides of the first wiring channel 3121 along the thickness direction Y of the positioning plate 311. Thus, the wire harness 42 can be confined within the first wiring channel 3121 by the at least two limiting protrusions 3123, so that the wire harness 42 is isolated from the outer peripheral surface 111 of the battery cell 11.

[0052] Among them, such as Figure 8As shown, the wiring structure 3122 may include three limiting protrusions 3123. Two of the three limiting protrusions 3123 are located on the same side of the first wiring channel 3121 and are close to the same first concave surface 3112. The other of the three limiting protrusions 3123 is located on the other side of the first wiring channel 3121 and is located away from the first concave surface 3112.

[0053] Of course, the wiring structure 3122 may also include two, four or more limiting protrusions 3123, as long as at least two limiting protrusions 3123 are located on both sides of the first wiring channel 3121 and can limit the wire harness 42 within the first wiring channel 3121.

[0054] At least one limiting protrusion 3123 has a first anti-detachment part 3124 protruding from one end away from the positioning plate 311. The first anti-detachment part 3124 is located on the side of the limiting protrusion 3123 facing the first wiring channel 3121. Thus, the first anti-detachment part 3124 can abut and limit the wire harness 42 in the first wiring channel 3121, reducing the risk of the wire harness 42 detaching from the first wiring channel 3121 in a direction away from the positioning plate 311.

[0055] It should be noted that at least one limiting protrusion 3123 of a portion of the wiring structure 3122 may be provided with a first anti-detachment part 3124, or at least one limiting protrusion 3123 of all wiring structures 3122 may be provided with a first anti-detachment part 3124. Of course, the latter can further improve the limiting effect on the wire harness 42.

[0056] Specifically, a wiring structure 3122 is provided for each first concave surface 3112. At least one limiting protrusion 3123 of the wiring structure 3122 is close to the corresponding first concave surface 3112, and at least another limiting protrusion 3123 is far away from the first concave surface 3112.

[0057] Of course, the first wiring channel 3121 can also pass through the wiring structure 3122 to form a through hole or a groove-shaped first wiring channel 3121.

[0058] In some embodiments, such as Figures 4 to 6 As shown, the positioning plate 311 may also have multiple supporting protrusions 313 protruding on one side of its width direction Z, and these supporting protrusions 313 are arranged along the length direction X of the positioning plate 311. Therefore, when the cell positioning frame 31 is placed between two adjacent rows of cells 11, the positioning plate 311 can be supported on the base plate below the cells 11 by the multiple supporting protrusions 313, giving the positioning plate 311 a certain height for better positioning of the cells 11. At the same time, it can also reduce the material used in the cell positioning frame 31, which helps to reduce the weight and cost of the cell positioning frame 31.

[0059] Specifically, at least two support protrusions 313 can be located at both ends of the positioning plate 311 along its length X, so that the support protrusions 313 can stably support the positioning plate 311. Alternatively, at least one support protrusion 313 can be located at the middle of the positioning plate 311 along its length X, to further improve the support stability of the positioning plate 311.

[0060] In this embodiment, the multiple support protrusions 313 and the first wiring portion 312 can be located on the same side of the positioning plate 311. Alternatively, the multiple support protrusions 313 and the first wiring portion 312 can be located on both sides of the positioning plate 311. Of course, the former allows the wiring harness 42 to be located below the positioning plate 311, which is beneficial when the wiring harness 42 is connected to the temperature probe 41, allowing the temperature probe 41 to be closer to the end of the battery cell 11 where the electrode post is located.

[0061] In some embodiments, the multiple support protrusions 313 and the first wiring portion 312 may be located on the same side of the positioning plate 311. Moreover, in the width direction Z of the positioning plate 311, the height of the support protrusions 313 is greater than the height of the first wiring portion 312, so that the first wiring portion 312 maintains a certain distance from the bottom plate below the battery cell 11.

[0062] In some embodiments, a mounting portion 3131 may be provided on one side of the positioning plate 311 in the width direction Z. This mounting portion 3131 has a mounting groove 3132 for mounting the temperature probe 41. Thus, the temperature probe 41 of the temperature monitoring component can be installed in the mounting groove 3132 of the mounting portion 3131, thereby making the installation of the temperature probe 41 more stable and convenient.

[0063] The mounting portion 3131 and the first wiring portion 312 can be distributed on both sides of the positioning plate 311 along the width direction Z. This allows the temperature probe 41 to be positioned as close as possible to the end of the battery cell 11 where the electrode post is located, thereby improving the accuracy of the temperature probe 41 in monitoring the temperature of the battery cell 11.

[0064] like Figure 5 As shown, the mounting groove 3132 extends through the mounting portion 3131 along the width direction Z of the positioning plate 311. The positioning plate 311 has a through hole 3113 communicating with the mounting groove 3132. This through hole 3113 extends through the positioning plate 311 along the width direction Z of the positioning plate 311. Therefore, the wire harness 42 can be connected to the temperature probe 41 in the mounting groove 3132 through the through hole 3113, making the connection between the wire harness 42 and the temperature probe 41 more convenient. Furthermore, the end of the wire harness 42 connected to the temperature probe 41 is limited by the through hole 3113.

[0065] In some embodiments, such as Figure 3As shown, the mounting portion 3131 includes a second concave surface 3134 adapted to the outer peripheral surface 111 of the battery cell 11, and a mounting groove 3132 is formed in the second concave surface 3134 with a slot 3133. Therefore, when the temperature probe 41 is placed in the mounting groove 3132, the temperature probe 41 can directly or indirectly contact the outer peripheral surface 111 of the battery cell 11 through the slot 3133 or through a heat-conducting component, thereby improving the accuracy of the temperature probe 41 in detecting the temperature of the battery cell 11.

[0066] Thermally conductive adhesive 50 can be filled between the inner circumferential surface of the temperature probe 41 and the mounting groove 3132, so that the temperature probe 41 can contact the outer circumferential surface 111 of the battery cell 11 through the thermally conductive adhesive 50, and the heat of the battery cell 11 can be quickly transferred to the temperature probe 41 through the thermally conductive adhesive 50, which is beneficial to improving the accuracy of the temperature probe 41 in monitoring the temperature of the battery cell 11.

[0067] In some embodiments, the width direction Z of the wire harness 42 located in the first wiring channel 3121 can be aligned with the width direction Z of the positioning plate 311 of the cell positioning frame 31. This reduces the space occupied by the wire harness 42 in the thickness direction Y of the positioning plate 311 within the first wiring channel 3121, which helps to reduce the minimum gap between adjacent rows of cells 11.

[0068] The thickness H of the wire harness 42 of the bracket assembly 30 can be less than or equal to the minimum spacing L between two adjacent rows of cells 11, so that the wire harness 42 can be accommodated between two adjacent rows of cells 11.

[0069] In addition, the width W of the wire harness 42 of the bracket assembly 30 can be greater than the minimum spacing L between two adjacent rows of cells 11, so that the wire harness 42 has sufficient size to stably transmit temperature signals.

[0070] Specifically, such as Figure 9 As shown, the thickness H of the wire harness 42 can be greater than or equal to 1.28 mm and less than or equal to 1.48 mm. Furthermore, the minimum spacing L between two adjacent rows of cells 11 is greater than or equal to 2.55 mm and less than or equal to 2.75 mm. Therefore, the thickness H of the wire harness 42 can be less than the minimum spacing L between two adjacent rows of cells 11. Specifically, the thickness H of the wire harness 42 can be 1.3 mm, 1.38 mm, 1.4 mm, etc., and the minimum spacing L between two adjacent rows of cells 11 can be 2.6 mm, 2.65 mm, 2.7 mm, etc.

[0071] Alternatively, the width W of the wire harness 42 can be greater than or equal to 2.9 mm and less than or equal to 3.1 mm, thereby making the width W of the wire harness 42 greater than the minimum spacing L between two adjacent rows of battery cells 11. The width W of the wire harness 42 can be 2.95 mm, 3 mm, 3.05 mm, etc.

[0072] In some embodiments, such as Figure 8 As shown, a second wiring portion 314 is provided at least one end of the positioning plate 311 in the length direction X, and the second wiring portion 314 defines a second wiring channel 3141 extending in the width direction Z of the positioning plate 311. Therefore, the portion of the wire harness 42 near the end of the positioning plate 311 can be installed in the second wiring channel 3141, making the installation position of the wire harness 42 more stable and facilitating the extension of the end of the wire harness 42 away from the temperature probe 41 along the width direction Z of the positioning plate 311 to connect with the connector.

[0073] It should be noted that the second wiring channel 3141 can be a channel defined by the second wiring section 314, or the second wiring channel 3141 can be a slot, a through hole or other space that can accommodate the wire harness 42.

[0074] The second wiring section 314 can be located on one side of the positioning plate 311 in the thickness direction Y. This allows full use of the space on both sides of the positioning plate 311 in the thickness direction Y, ensuring that the installation of the second wiring section 314 does not increase the total length of the cell positioning frame 31.

[0075] In some embodiments, the second wiring portion 314 includes a plurality of limiting portions 3142 protruding from the positioning plate 311. The plurality of limiting portions 3142 are distributed on both sides of the second wiring channel 3141, thereby confining the wire harness 42 within the second wiring channel 3141. A second anti-detachment portion 3143 protrudes from the side of the limiting portion 3142 facing the second wiring channel 3141. Thus, the second anti-detachment portion 3143 can abut against the wire harness 42 within the second wiring channel 3141 to prevent the wire harness 42 from detaching from the second wiring channel 3141 in a direction away from the positioning plate 311.

[0076] Of course, the second wiring channel 3141 can also pass through the second wiring section 314, so that the second wiring channel 3141 is a groove or through hole structure.

[0077] In some embodiments, the first concave surface 3112 of the positioning plate 311 can be bonded to the outer peripheral surface 111 of the corresponding battery cell 11, thereby improving the connection stability between the positioning plate 311 and the battery cell 11, and thus improving the positioning effect of the battery cell positioning frame 31 on the battery cell 11.

[0078] In this design, at least one first concave surface 3112 of the positioning plate 311 may be provided with an adhesive groove 3114. Adhesive can be placed in the adhesive groove 3114. When the first concave surface 3112 of the positioning plate 311 is attached to the corresponding outer peripheral surface 111 of the battery cell 11, the first concave surface 3112 can be stably bonded to the outer peripheral surface 111 of the battery cell 11 through the adhesive in the adhesive groove 3114. This prevents the adhesive from being squeezed out by the first concave surface 3112 and the outer peripheral surface 111 of the battery cell 11, thus avoiding affecting the bonding effect between the first concave surface 3112 and the outer peripheral surface 111 of the battery cell 11.
