Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a cell positioning frame, a support assembly, and a battery module. Background Technology

[0002] In related technologies, multiple cells in a battery module are typically positioned using plastic brackets to maintain spacing and insulation between rows of cells. Temperature probes are also installed between the cells to monitor their temperature and transmit the temperature signals via wiring harnesses.

[0003] However, the wiring harness connected to the temperature probe is usually placed between the battery cells. Due to the small gap between the battery cells, it is difficult to set up the wiring harness connected to the temperature probe. Utility Model Content

[0004] The embodiments of this application provide a cell positioning frame, a support assembly, and a battery module, which can improve the technical problem that the small gap between the cells of the battery module makes it difficult to set up the wiring harness connected to the temperature probe.

[0005] In a first aspect, embodiments of this application provide a cell positioning frame, comprising:

[0006] A positioning plate, the positioning plate comprising plate surfaces located on both sides in its thickness direction, at least a portion of the plate surfaces being adapted to the outer peripheral surface of the battery cell;

[0007] The wiring section is located on one side of the positioning plate in the width direction. The wiring section forms a wiring channel extending along the length direction of the positioning plate. The width of the wiring channel in the thickness direction is greater than or equal to 1.6 mm and less than or equal to 2.2 mm.

[0008] In some embodiments, the wiring portion includes a plurality of limiting protrusions protruding from one side of the positioning plate in the width direction, the plurality of limiting protrusions being distributed on both sides of the wiring channel along the thickness direction of the positioning plate. The plurality of limiting protrusions can confine the wire harness within the wiring channel, keeping the wire harness isolated from the outer peripheral surface of the battery cell.

[0009] In some embodiments, the length of the limiting protrusion is greater than or equal to 2 mm and less than or equal to 4 mm in the length direction. This allows the limiting protrusion to have a relatively long length, effectively limiting the wire harness while avoiding material waste caused by excessive length of the limiting protrusion.

[0010] In some embodiments, in the thickness direction, the thickness of the limiting protrusion is greater than or equal to 1 mm and less than or equal to 1.5 mm, so that the limiting protrusion has high strength and can effectively limit the wire harness. At the same time, it avoids the limiting protrusion being too thick, which would cause the limiting protrusion to occupy too much space and increase the overall thickness of the cell positioning frame.

[0011] In some embodiments, at least one of the limiting protrusions has an anti-detachment portion at one end away from the positioning plate, and the anti-detachment portion is located on the side of the limiting protrusion facing the wiring channel. The anti-detachment portion can abut and limit the wire harness in the wiring channel, reducing the risk of the wire harness detaching from the wiring channel in a direction away from the positioning plate.

[0012] In some embodiments, the minimum distance between the anti-detachment portion of the limiting protrusion located on one side of the wiring channel and the limiting protrusion located on the other side of the wiring channel is greater than or equal to 0.8 mm and less than or equal to 1.2 mm. This allows the anti-detachment portion to effectively confine the wire harness within the wiring channel. At the same time, it also prevents the minimum distance between the anti-detachment portion of the limiting protrusion located on one side of the wiring channel and the limiting protrusion located on the other side of the wiring channel from being too small, which would make it difficult to install the wire harness into the wiring channel.

[0013] In some embodiments, the wiring channel includes a bottom surface spaced apart from the anti-detachment part. In the width direction of the positioning plate, the distance between the bottom surface and the anti-detachment part is greater than or equal to 3 mm and less than or equal to 5 mm. This ensures sufficient space between the anti-detachment part and the bottom surface of the wiring channel to accommodate the wire harness, while preventing excessive spacing between them from causing the wire harness to sway within the wiring channel.

[0014] In some embodiments, the cell positioning frame further includes a plurality of mounting portions located on one side of the positioning plate along the width direction and spaced apart along the length direction. Each mounting portion forms a mounting groove for mounting a temperature probe. This allows the temperature probe of the temperature monitoring component to be mounted within the mounting groove of the mounting portion, making the installation of the temperature probe more stable and convenient.

[0015] Secondly, embodiments of this application provide a support assembly, including:

[0016] A battery cell positioning frame, as described above, includes a positioning plate and a wiring section. The positioning plate includes plate surfaces located on both sides in its thickness direction. Each plate surface includes a plurality of first concave surfaces arranged along the length direction of the positioning plate, the first concave surfaces being adapted to the outer peripheral surface of the battery cell. The wiring section is located on one side of the positioning plate in the width direction, and the wiring section forms a wiring channel extending along the length direction of the positioning plate. The width of the wiring channel in the thickness direction is greater than or equal to 1.6 mm and less than or equal to 2.2 mm.

[0017] The temperature monitoring component includes a temperature probe and a wiring harness that are interconnected. The temperature probe is mounted on the cell positioning frame, and the wiring harness is mounted in the wiring channel of the cell positioning frame.

[0018] Thirdly, embodiments of this application provide a battery module, including:

[0019] Battery cell assembly, comprising multiple rows of battery cells spaced apart;

[0020] The bracket assembly is as described above, and the bracket assembly is provided between two adjacent rows of the battery cells.

[0021] In some embodiments, there are multiple support assemblies, with multiple rows of battery cells arranged between adjacent support assemblies. Therefore, multiple support assemblies can detect the temperature of battery cells at different locations within the battery assembly via temperature monitoring components, which helps improve the accuracy of battery assembly temperature detection.

[0022] In some embodiments, at least four rows of battery cells are arranged between two adjacent support assemblies. This allows for effective temperature monitoring of various parts of the battery assembly while minimizing the number of support assemblies, thus reducing the cost of the battery module.

[0023] In some embodiments, at least one of the support assemblies is located between the first row of cells and the second row of cells to facilitate temperature detection in the edge region of the battery module near the width direction; and / or, at least one of the support assemblies is located between the last row of cells and the penultimate row of cells to facilitate temperature detection in the edge region of the battery module near the width direction.

[0024] The beneficial effects of the embodiments of this application are as follows:

[0025] In this embodiment, the positioning plate of the battery cell positioning frame includes plate surfaces located on both sides of its thickness direction, and the plate surfaces include a plurality of first concave surfaces disposed along the length direction of the positioning plate and adapted to the outer peripheral surface of the battery cell. When the positioning plate is placed between two adjacent rows of battery cells, each of the first concave surfaces of the positioning plate is adapted to the outer peripheral surface of the corresponding battery cell to position the two adjacent rows of battery cells.

[0026] Building upon this, a wiring section is provided on one side of the positioning plate in the width direction, forming a wiring channel extending along the length direction of the positioning plate. The width of this channel in the thickness direction is greater than or equal to 1.6 mm and less than or equal to 2.2 mm. This allows the wiring harness connected to the temperature probe to be installed within the wiring channel, extending along the length of the positioning plate between adjacent rows of cells. The installation of the wiring harness is more stable and convenient, unaffected by cell interference, thus improving the assembly efficiency of the battery module. Simultaneously, by ensuring the width of the wiring channel in the thickness direction is greater than or equal to 1.6 mm and less than or equal to 2.2 mm, the channel can accommodate the wiring harness without making the positioning plate too thick, allowing the cell positioning frame to be suitable for battery modules with small cell gaps.

Detailed Implementation

[0036] 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.

[0037] This application provides a cell positioning frame, a support assembly, and a battery module. These will be described in detail below.

[0038] Figure 1 This is a perspective view of one embodiment of the battery module provided in this application. Figure 2 This is a top view of one embodiment of the battery assembly and support assembly provided in this application. Figure 1 and Figure 2 As 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.

[0039] The battery module 1 may also include a foam that wraps at least a portion of the cell 11 assembly to position and protect the multiple cells 11 of the cell 11 assembly.

[0040] In addition, such as Figure 2As 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 support 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, and at least a portion of the plate surfaces 3111 adapts to the outer peripheral surface 111 of the cell 11. The plate surfaces 3111 may include a plurality of first concave surfaces 3112 disposed along the length direction X of the positioning plate 311, and these first concave surfaces 3112 adapt to the outer peripheral surface 111 of the cell 11.

[0041] 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.

[0042] 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 11, the first concave surface 3112 and the outer peripheral surface 111 of the battery cell 11 have similar or identical arc surfaces.

[0043] 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 between the adjacent rows of cells 11.

[0044] In some embodiments, at least a portion of the bracket assembly 30 may be wrapped with expanding foam 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.

[0045] 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, so that the expanding foam encapsulates 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, so that the expanding foam encapsulates the cell positioning frame 31.

[0046] In some embodiments, such as Figures 4 to 6 As shown, the cell positioning frame 31 also includes a wiring section 312, which is located on one side of the positioning plate 311 in the width direction Z, and forms a wiring channel 3121 extending along the length direction X of the positioning plate 311. This allows the wiring harness 42 connected to the temperature probe 41 to be installed within the wiring channel 3121, extending 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, thus improving the assembly efficiency of the battery module 1. Simultaneously, by ensuring that the width of the wiring channel 3121 in the thickness direction Y is greater than or equal to 1.6 mm and less than or equal to 2.2 mm, the wiring channel 3121 can accommodate the wiring harness 42 without causing the positioning plate 311 to become excessively thick. This allows the cell positioning frame 31 to be suitable for battery modules 1 with smaller gaps between the cells 11.

[0047] It should be noted that the wiring channel 3121 can be a channel defined by the wiring structure 3122, or the wiring channel 3121 can be a slot, a through hole, or other space that can accommodate the wire harness 42.

[0048] The wiring section 312 may include a plurality of limiting protrusions 3123 protruding from one side of the positioning plate 311 in the width direction Z. These limiting protrusions 3123 are distributed on both sides of the wiring channel 3121 along the thickness direction Y of the positioning plate 311. Thus, the wiring harness 42 can be confined within the wiring channel 3121 by the multiple limiting protrusions 3123, keeping the wiring harness 42 isolated from the outer peripheral surface 111 of the battery cell 11.

[0049] In some embodiments, at least one limiting protrusion 3123 may have an anti-detachment portion 3124 protruding from one end away from the positioning plate 311, with the anti-detachment portion 3124 located on the side of the limiting protrusion 3123 facing the wiring channel 3121. Thus, the anti-detachment portion 3124 can abut and limit the wire harness 42 within the wiring channel 3121, reducing the risk of the wire harness 42 detaching from the wiring channel 3121 in a direction away from the positioning plate 311.

[0050] It should be noted that some of the multiple limiting protrusions 3123 may be provided with anti-detachment parts 3124, or all of the limiting protrusions 3123 may be provided with anti-detachment parts 3124. Of course, the latter can further improve the limiting effect on the wire harness 42.

[0051] In some embodiments, the routing portion 312 includes routing structures 3122 respectively disposed corresponding to a plurality of first concave surfaces 3112, and each routing structure 3122 includes at least two limiting protrusions 3123. The at least two limiting protrusions 3123 of the routing structures 3122 are spaced apart along the length direction X, and are distributed along the thickness direction Y on both sides of the routing channel 3121. The routing structures 3122 correspond to the first concave surfaces 3112 at their respective locations. At least one limiting protrusion 3123 of the routing structure 3122 is located on the side of the routing channel 3121 closest to the first concave surface 3112 corresponding to the routing structure 3122. At least another limiting protrusion 3123 of the routing structure 3122 is located on the side of the routing channel 3121 away from the first concave surface 3112 corresponding to the routing structure 3122.

[0052] Specifically, the trace structure 3122 may include three limiting protrusions 3123, one of which is located on the side of the trace channel 3121 near the first concave surface 3112 corresponding to the trace structure 3122. The other two limiting protrusions 3123 are located on the side of the trace channel 3121 away from the first concave surface 3112 corresponding to the trace structure 3122. Moreover, in the length direction X, one of the limiting protrusions 3123 is located between the other two limiting protrusions 3123.

[0053] In some embodiments, the length of the limiting protrusion 3123 in the length direction X can be greater than or equal to 2 mm and less than or equal to 4 mm. This allows the limiting protrusion 3123 to have a relatively long length, effectively limiting the wire harness 42 while avoiding material waste due to excessive length of the limiting protrusion 3123.

[0054] The length of the limiting protrusion 3123 can be 2.2mm, 2.4mm, 2.7mm, 3mm, 3.1mm, 3.5mm, 3.8mm, etc., depending on the structure of the limiting protrusion 3123 and the positioning plate 311.

[0055] Furthermore, in the thickness direction Y, the thickness of the limiting protrusion 3123 can be greater than or equal to 1 mm and less than or equal to 1.5 mm to give the limiting protrusion 3123 high strength, enabling it to effectively limit the wire harness 42. At the same time, it avoids the limiting protrusion 3123 being too thick, which would cause it to occupy too much space and increase the overall thickness of the cell positioning frame 31.

[0056] The thickness of the limiting protrusion 3123 can be 1.2mm, 1.3mm, 1.4mm, etc., depending on the structure of the limiting protrusion 3123 and the positioning plate 311.

[0057] In some embodiments, such as Figure 6 As shown, the anti-detachment part 3124 of the limiting protrusion 3123 on one side of the wiring channel 3121 and the limiting protrusion 3123 on the other side of the wiring channel 3121 can have a relative distance H1 in the thickness direction Y that is greater than or equal to 0.8 mm and less than or equal to 1.2 mm. This allows the anti-detachment part 3124 to effectively confine the wire harness 42 within the wiring channel 3121. At the same time, it can also prevent the minimum distance between the anti-detachment part 3124 of the limiting protrusion 3123 on one side of the wiring channel 3121 and the limiting protrusion 3123 on the other side of the wiring channel 3121 from being too small, which would make it difficult to install the wire harness 42 into the wiring channel 3121.

[0058] The anti-detachment part 3124 of the limiting protrusion 3123 located on one side of the wiring channel 3121 and the relative distance H1 of the limiting protrusion 3123 located on the other side of the wiring channel 3121 in the thickness direction Y can be 0.83mm, 0.86mm, 0.88mm, 0.9mm, 0.97mm, 1mm, 1.07mm, 1.1mm, 1.15mm, 1.18mm, etc.

[0059] In some embodiments, the wiring channel 3121 includes a bottom surface spaced apart from the anti-detachment part 3124. In the width direction Z of the positioning plate 311, the distance H2 between the bottom surface and the anti-detachment part 3124 is greater than or equal to 3 mm and less than or equal to 5 mm. This ensures sufficient space between the anti-detachment part 3124 and the bottom surface of the wiring channel 3121 to accommodate the wire harness 42, while preventing excessive spacing between the anti-detachment part 3124 and the bottom surface of the wiring channel 3121, which could cause the wire harness 42 to sway within the wiring channel 3121.

[0060] The distance H2 between the bottom surface and the anti-detachment part 3124 can be 3.2mm, 3.5mm, 3.8mm, 4mm, 4.2mm, 4.6mm, etc., and there is no restriction here.

[0061] In some embodiments, such as Figure 3 As shown, the cell positioning frame 31 may also include multiple mounting portions 3131, which are located on one side of the positioning plate 311 along the width direction Z. These mounting portions 3131 are spaced apart along the length direction X, and each mounting portion 3131 forms a mounting groove 3132 for mounting a temperature probe 41. Therefore, the temperature probe 41 of the temperature monitoring component can be installed in the mounting groove 3132 of the mounting portion 3131, making the installation of the temperature probe 41 more stable and convenient.

[0062] It should be noted that the mounting part 3131 can form one or more mounting slots 3132, and each mounting slot 3132 can be used to mount the temperature probe 41.

[0063] Multiple mounting portions 3131 and wiring portions 312 can be distributed along the width direction Z on both sides of the positioning plate 311. That is, the wiring portions 312 are located on one side of the positioning plate 311 along the width direction Z, and the multiple mounting portions 3131 are located on the other side of the positioning plate 311 along the width direction Z. As a result, the temperature probe 41 can 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] In some embodiments, such as Figure 3 and Figure 6 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 3 As 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 can be filled between the inner circumferential surface of the temperature probe 41 and the mounting groove 3132, so that the temperature probe 41 contacts the outer circumferential surface 111 of the battery cell 11 through the thermally conductive adhesive. This allows the heat of the battery cell 11 to be quickly transferred to the temperature probe 41 through the thermally conductive adhesive, which helps to improve the accuracy of the temperature probe 41 in monitoring the temperature of the battery cell 11.

[0067] In some embodiments, such as Figure 6As shown, a wire-clamping structure 314 may be provided on at least one side of the positioning plate 311 in the thickness direction Y. This wire-clamping structure 314 defines a wire-clamping channel 3141 extending along the width direction Z of the positioning plate 311. Thus, the wire outlet section of the wire harness 42 can be installed within the wire-clamping channel 3141, making the installation position of the wire harness 42 more stable and facilitating the connection of the wire harness 42 to the connector on the side of the positioning plate 311 in the width direction Z, away from the temperature probe 41.

[0068] It should be noted that the wire-clamping channel 3141 can be a channel defined by the wire-clamping structure 314, or the wire-clamping channel 3141 can be a slot, a through hole, or other space that can accommodate the wire harness 42.

[0069] In some embodiments, the wire-holding structure 314 includes a plurality of limiting portions 3142 protruding from one side of the positioning plate 311 in the thickness direction Y. The plurality of limiting portions 3142 are distributed on both sides of the wire-holding channel 3141, thereby confining the wire harness 42 within the wire-holding channel 3141. An anti-detachment protrusion 3143 is provided on the side of the limiting portion 3142 facing the wire-holding channel 3141. Thus, the anti-detachment protrusion 3143 can abut against the wire harness 42 within the wire-holding channel 3141 to prevent the wire harness 42 from detaching from the wire-holding channel 3141 in a direction away from the positioning plate 311.

[0070] Of course, the wire-clamping channel 3141 can also pass through the wire-clamping structure 314, so that the wire-clamping channel 3141 is a groove or through hole structure.

[0071] This application also provides a support assembly, which includes a cell positioning frame. The specific structure of the cell positioning frame is as described in the above embodiments. Since this support assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0072] The bracket assembly 30 may include a cell positioning frame 31 and a temperature monitoring component. The structure of the cell positioning frame 31 may refer to the above embodiments. The temperature monitoring component includes a temperature probe 41 and a wire harness 42 connected to each other. The temperature probe 41 is installed on the cell positioning frame 31, and the wire harness 42 is installed in the wiring channel 3121 of the cell positioning frame 31.

[0073] This application also provides a battery module, which includes a bracket assembly. The specific structure of the bracket assembly is as described in the above embodiments. Since this battery module adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] The battery module 1 may include a battery assembly 10 and a support assembly 30. The battery assembly 10 includes multiple rows of cells 11 arranged at intervals. A support assembly 30 is provided between two adjacent rows of cells 11. The structure of the support assembly 30 can refer to the above embodiments.

[0075] In some embodiments, the number of support assemblies 30 can be multiple, with multiple rows of battery cells 11 arranged between adjacent support assemblies 30. Thus, multiple support assemblies 30 can detect the temperature of the battery cells 11 at different locations in the battery assembly 10 via a temperature monitoring component, which helps improve the accuracy of temperature detection in the battery assembly 10.

[0076] This design allows for the arrangement of at least four rows of battery cells 11 between two adjacent support assemblies 30. This enables effective temperature monitoring of various parts of the battery assembly 10 while minimizing the number of support assemblies 30, thus reducing the cost of the battery module 1.
