[0005] With the rapid development of new energy technologies, new energy batteries are emerging in an endless stream. While people are placing higher and higher demands on the performance of new energy batteries, battery safety is also receiving more and more attention.

[0006] In order to ensure sufficient safety, most batteries on the market are equipped with temperature sensors. The temperature sensor is adhered to the large surface of the battery cell through thermal conductive structural adhesive. A clamping bracket is set above the temperature sensor and connected to the temperature sensor through the back adhesive, so that the temperature sensor is clamped by the clamping bracket.

[0007] Technical issues

[0008] However, since the clamping bracket is formed by vacuum molding, when the battery pack vibrates, the clamping bracket cannot clamp the temperature sensor, and may even cause the temperature sensor to detach from the battery cell, resulting in inaccurate temperature collection by the temperature sensor, ultimately posing a safety hazard.

[0010] In one aspect of the present application, a temperature sensor fixing assembly is provided, comprising:

[0011] A fixed bracket, the fixed bracket having a pressing end and a connecting end, the pressing end is configured to press the temperature sensor, and the connecting end has a first clamping structure;

[0012] The connecting row and the corresponding connecting end of the connecting row are provided with a second clamping structure that cooperates with the first clamping structure. When the first clamping structure and the second clamping structure are clamped with each other, the pressing end can press the temperature sensor.

[0013] In some implementations, one of the first and second clamping structures is a clamping plate having a clamping space, and the other is a clamping plug-in plate, at least a portion of which extends into the clamping space and is clamped to the clamping plate.

[0014] In some implementations, the card space is interference-fitted with the card board.

[0015] In some implementations, the snap-fitting plate includes a first plate segment and a second plate segment spaced apart along a height direction, with a snap-fitting space between the first plate segment and the second plate segment. When the first snap-fitting structure and the second snap-fitting structure are snapped into each other, the first plate segment and the second plate segment respectively abut against two sides of the snap-fitting plate.

[0016] In some implementations, the first plate segment is located above the second plate segment, the second plate segment has at least one snap-fit ​​protrusion on a side facing the first plate segment, and the snap-fit ​​board has at least one snap-fit ​​through hole that cooperates with the at least one snap-fit ​​protrusion.

[0017] In some implementations, the first plate segment is provided with a deformation notch corresponding to the clamping protrusion, and the deformation notch is opposite to the clamping protrusion.

[0018] In some implementations, at least one of the sides of the first board segment and the card patch panel that abut against each other has an abutting slope.

[0019] In some implementations, the pressing end is provided with a receiving groove, the temperature sensor is disposed in the receiving groove, and the temperature sensor fixing assembly further includes a thermal pad, which is disposed on a side of the temperature sensor facing away from the fixing bracket.

[0020] In some implementations, the receiving groove is in an inverted U shape.

[0021] In some implementations, the fixing bracket further includes at least two connecting members, at least one connecting member is respectively provided on both sides of the fixing bracket in the width direction, and the fixing bracket is configured to be connected to the CCS bracket through the connecting members.

[0024] In some implementations, the width of the compression end is smaller than the width of the connection end.

[0025] Another aspect of the present application provides a CCS assembly, including: a temperature sensor fixing assembly and battery cells, wherein there are multiple battery cells and connecting bars, the connecting bars connect the battery cells, and the temperature sensor abuts the battery cells.

[0026] In another aspect of the present application, a battery pack is provided, including a CCS assembly and an aluminum busbar.

[0027] Beneficial effects

[0028] Applying the technical solution of the present application, the temperature sensor fixing assembly includes a fixed bracket and a connecting row. The fixed bracket has a clamping end and a connecting end. The clamping end is configured to clamp the temperature sensor, and the connecting end has a first clamping structure. The corresponding connecting end of the connecting row is provided with a second clamping structure that cooperates with the first clamping structure. When the first clamping structure and the second clamping structure are clamped with each other, the clamping end can clamp the temperature sensor. The first clamping structure of the connecting end is clamped with the second clamping structure on the connecting row, so that the connecting row clamps the fixed bracket and then compresses the temperature sensor. Since the fixed bracket is clamped with the connecting row, the position of the connecting row is fixed, which can prevent the fixed bracket from moving when it is vibrated, and thus prevent the temperature sensor from moving and causing errors in temperature detection, avoiding safety hazards, and thus improving the accuracy of temperature detection.

[0045] The present application provides a temperature sensor fixing assembly, a CCS assembly, and a battery pack, wherein the battery pack includes the CCS assembly.

[0046] As shown in Figures 1 to 6, the temperature sensor mounting assembly includes a mounting bracket 10 and a connecting bar 20. The mounting bracket 10 has a clamping end 11 and a connecting end 12. The clamping end 11 is configured to clamp the temperature sensor 30, and the connecting end 12 has a first engaging structure 121. The connecting bar 20 is provided with a second engaging structure 21 corresponding to the connecting end 12, which cooperates with the first engaging structure 121. When the first engaging structure 121 and the second engaging structure 21 are engaged with each other, the clamping end 11 can compress the temperature sensor 30.

[0047] By engaging the first engaging structure 121 of the connecting end 12 with the second engaging structure on the connecting row 20, the connecting row 20 is able to press the fixing bracket 10 and further compress the temperature sensor 30. Since the fixing bracket 10 is engaged with the connecting row 20, the position of the connecting row 20 is fixed, which can prevent the fixing bracket 10 from moving when subjected to vibration, and thus prevent the temperature sensor 30 from moving, causing errors in temperature detection and avoiding safety hazards, thereby improving the compression and fixing effect of the temperature sensor 30.

[0048] As shown in Figures 3 and 5, one of the first clamping structure 121 and the second clamping structure 21 is a clamping clamp 100, which has a clamping space, and the other is a clamping plug-in plate 110, at least a portion of which extends into the clamping space and is clamped to the clamping clamp 100.

[0049] One of the first clamping structure 121 and the second clamping structure 21 is a clamping plate 100 , and the other is a clamping plug-in plate 110 . The clamping plug-in plate 110 is inserted into the clamping space to enable the fixing bracket 10 to press the connecting row 20 or the connecting row 20 to press the fixing bracket 10 .

[0050] In this embodiment, the first engaging structure 121 has an engaging space, and the second engaging structure 21 is a engaging plate 110. During installation, the pressing end 11 of the fixed bracket 10 presses against the temperature sensor 30. The end of the connecting bar 20 adjacent to the fixed bracket 10 is formed with a downwardly concave engaging plate 110. The connecting bar 20 is installed toward the fixed bracket 10, so that the engaging plate 110 extends into the engaging space. The connecting bar 20 compresses the fixed bracket 10, thereby ensuring that the temperature sensor 30 is fixed in a fixed position.

[0051] Optionally, the first clamping structure 121 is a clamping plug-in board 110 , and the second clamping structure 21 has a clamping space. The specific setting method can be selected according to actual needs.

[0052] In this embodiment, the card space and the card board 110 are interference fit.

[0053] The interference fit method can ensure the connection reliability between the first clamping structure 121 and the second clamping structure. Even if subjected to vibration or impact, the fixing bracket 10 and the connecting row 20 still maintain the same relative position.

[0054] As shown in Figures 3 to 6, the snap-fitting clamp 100 includes a first plate segment 101 and a second plate segment 102 spaced apart along the height direction, and there is a snap-fitting space between the first plate segment 101 and the second plate segment 102. When the first snap-fitting structure 121 and the second snap-fitting structure 21 are snapped into each other, the first plate segment 101 and the second plate segment 102 respectively abut against both sides of the snap-fitting plate 110.

[0055] The lengths of the first plate segment 101 and the second plate segment 102 are adapted to the length of the card board 110 to ensure that the first plate segment 101 and the second plate segment 102 have a sufficiently large contact area with the card board 110 .

[0056] In this embodiment, the first plate segment 101 is located above the second plate segment 102, and the second plate segment 102 has at least one snap-fit ​​protrusion 103 on the side facing the first plate segment 101, and the snap-fit ​​plug-in board 110 has at least one snap-fit ​​through hole 211 that cooperates with at least one snap-fit ​​protrusion 103.

[0057] For example, there are two engaging protrusions 103 and two engaging through-holes 211, with the two engaging protrusions 103 spaced apart on the second plate segment 102 and the two engaging through-holes 211 correspondingly formed on the connecting bar 20. When the first plate segment 101 and the second plate segment 102 clamp the plug-in board 110, that is, when the first plate segment 101 and the second plate segment 102 respectively abut against two sides of the connecting bar 20, the engaging protrusions 103 extend into the engaging through-holes 211.

[0058] Optionally, the number of the engaging protrusions 103 and engaging through-holes 211 can be greater to ensure the connection between the fixing bracket 10 and the connecting bar 20. The number of the engaging protrusions 103 and engaging through-holes 211 is not arbitrary. Too few engaging protrusions 103 and engaging through-holes 211 will reduce the connection between the fixing bracket 10 and the connecting bar 20. Too many engaging protrusions 103 and engaging through-holes 211 will not be conducive to the processing of the fixing bracket 10 and will reduce the structural strength of the connecting bar 20.

[0059] In another embodiment of the present application not shown, the snap-fit ​​protrusion 103 is provided on the first plate segment 101 , the second plate segment 102 presses the second snap-fit ​​structure 21 upward, and the snap-fit ​​protrusion 103 on the first plate segment 101 extends downward into the snap-fit ​​through hole 211 .

[0060] In this embodiment, at least one of the sides of the first plate segment 101 and the card board 110 that abut against each other has an abutting inclined surface 120 .

[0061] Illustratively, the upper surface of the card plug-in board 110 is horizontal, and the lower surface of the first plate segment 101 has an abutment slope 120. Optionally, the abutment slope 120 is tilted upward in a direction approaching the connection row 20 to facilitate the card plug-in board 110 entering the card connection space, while the extrusion force on the card plug-in board 110 gradually increases in a direction approaching the pressing end 11.

[0062] As shown in FIG. 4 , the first plate segment 101 is provided with a deformation notch 104 corresponding to the locking protrusion 103 , and the deformation notch 104 is opposite to the locking protrusion 103 .

[0063] Exemplarily, the deformation notch 104 is rectangular and corresponds to two snap-fit ​​protrusions 103. By providing the deformation notch 104, the structural strength of the first plate segment 101 can be reduced, so that a certain deformation occurs when the second snap-fit ​​structure 21 extends into the snap-fit ​​space of the first snap-fit ​​structure 121, thereby facilitating the second snap-fit ​​structure 21 to enter the snap-fit ​​space.

[0064] The arrangement of the deformation notch 104 corresponding to the snap-fit ​​protrusion 103 can avoid the snap-fit ​​protrusion 103 after the fixed bracket 10 is produced, thereby avoiding reducing the clamping force between the first plate segment 101 and the second plate segment 102. At the same time, when the fixed bracket 10 is connected to the connecting row 20, it is possible to observe through the deformation notch 104 whether the snap-fit ​​protrusion 103 and the snap-fit ​​through hole 211 are in place, thereby ensuring the accuracy and effectiveness of the assembly.

[0065] As shown in FIG3 , the pressing end 11 is provided with a receiving groove 14 , and the temperature sensor 30 is disposed in the receiving groove 14 . The temperature sensor fixing assembly further includes a thermal pad 80 , which is disposed on a side of the temperature sensor 30 facing away from the fixing bracket 10 .

[0066] Exemplarily, the temperature sensor 30 includes an aluminum substrate 31 and a sensor body 32. The sensor body 32 is disposed between the aluminum substrate 31 and the bottom of the receiving groove 14. The aluminum substrate 31 is sized to match the thermal pad 80. A thermally conductive adhesive is disposed between the thermal pad 80 and the aluminum substrate 31. Before the temperature sensor 30 is connected to the fixing bracket 10, the thermal pad 80 is bonded to the bottom surface of the temperature sensor 30. This improves assembly efficiency. The receiving groove 14 is adapted to the temperature sensor 30, compressing and positioning the temperature sensor 30 while also protecting it.

[0067] In this embodiment, the receiving groove 14 is in an inverted U shape.

[0068] The bottom of the accommodating groove 14 contacts the top surface of the temperature sensor 30 . Double-sided tape is provided on the top surface of the temperature sensor 30 , and the temperature sensor 30 is connected to the fixing bracket 10 through the double-sided tape.

[0069] As shown in FIG. 2 to FIG. 6 , the fixing bracket 10 further includes at least two connectors 13 . At least one connector 13 is provided on each side of the fixing bracket 10 in the width direction, and the fixing bracket 10 is connected to the CCS bracket 60 via the connectors 13 .

[0070] Exemplarily, the connecting member 13 is a riveted column, and the connecting row 20 is riveted to the CCS bracket 60. After riveting, the connecting row 20 is connected to the connecting end 12 on the fixed bracket 10 through the second clamping structure 21. Then, the fixed bracket 10 is riveted to the CCS bracket 60 through the connecting member 13. The setting of the two connecting members 13 can avoid the connection row 20 from being misaligned when it is installed.

[0071] In this embodiment, the fixing bracket 10 is an injection molded part. The structural hardness and strength of the fixing bracket 10 are greater than those of the CCS bracket 60 , thereby better pressing the temperature sensor 30 .

[0072] In this embodiment, the pressing end 11 and the connecting end 12 are respectively located at two ends of the fixing bracket 10 in the length direction.

[0073] Exemplarily, the two connecting members 13 are spaced apart along the width direction of the fixing bracket 10 .

[0074] In this embodiment, in the height direction of the fixing bracket 10 , the vertical distance between the pressing end 11 and the connecting row 20 is greater than the vertical distance between the connecting end 12 and the connecting row 20 .

[0075] In the height direction of the fixing bracket 10 , the pressing end 11 is located above the connecting end 12 , so that the connecting end 12 is pressed by the connecting row 20 and the pressing end 11 is driven to press the temperature sensor 30 .

[0076] In this embodiment, the width of the pressing end 11 is smaller than the width of the connecting end 12 .

[0077] The temperature sensor 30 is relatively small in width. By setting the width of the clamping end 11 to be smaller than the width of the connecting end 12 , the temperature sensor 30 can be better positioned to prevent it from moving. At the same time, the wider connecting end 12 can improve the connection effect between the connecting row 20 and the fixing bracket 10 .

[0078] The present application also provides a CCS assembly, which includes a temperature sensor fixing assembly and battery cells. There are multiple battery cells and connecting bars 20 . The connecting bars 20 connect the battery cells, and the temperature sensors 30 abut the battery cells.

[0079] The CCS assembly includes multiple temperature sensor fixing assemblies. Multiple connecting bars 20 connect multiple battery cells in series to form multiple battery strings. Multiple temperature sensors 30 are set on the multiple battery strings. The temperature sensors 30 are pressed and fixed to the battery cells by fixing brackets 10. The temperature sensors 30 collect heat data on the battery cells through thermal pads 80. The bonding of the thermal pads 80 and the temperature sensors 30 can speed up the assembly of the CCS assembly.

[0080] After multiple connecting bars 20 connect multiple battery cells in series, an output aluminum bar 40 is set on the connecting bar 20 at one end of any CCS assembly, and a flexible printed circuit (FPC) 50 is set between two adjacent battery strings.

[0081] The present application also provides a battery pack including a CCS assembly and an aluminum busbar.

[0082] Exemplarily, the battery pack includes two CCS assemblies, which are connected in parallel through parallel aluminum bars. One of the output aluminum bars 40 on the two CCS assemblies is connected to the positive electrode column, and the other is connected to the negative electrode column. Multiple PCB boards 70 are also provided at one end of the CCS assembly. The connecting bar 20, the flexible circuit board 50 and the battery management system (BMS) of the battery pack are all connected to the PCB board 70.

[0083] The embodiment of the present application achieves the following technical effects: by setting a temperature sensor fixing assembly including a fixing bracket 10 and a connecting row 20, the fixing bracket 10 has a clamping end 11 and a connecting end 12, the clamping end 11 is configured to clamp the temperature sensor 30, and the connecting end 12 has a first clamping structure 121, and the connecting row 20 is provided with a second clamping structure 21 corresponding to the connecting end 12, which cooperates with the first clamping structure 121. When the first clamping structure 121 and the second clamping structure 21 are clamped with each other, the clamping end 11 can clamp the temperature sensor 30, and the first clamping structure 121 of the connecting end 12 is clamped with the second clamping structure on the connecting row 20, so that the connecting row 20 presses the fixing bracket 10 and then presses the temperature sensor 30. Since the fixing bracket 10 is clamped with the connecting row 20, the position of the connecting row 20 is fixed, which can prevent the fixing bracket 10 from moving when subjected to vibration, and thus prevent the temperature sensor 30 from moving, thereby avoiding errors in temperature detection and safety hazards, thereby improving the clamping and fixing effect of the temperature sensor 30.
