Description

Battery collection components and battery packs

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 22, 2023, with application number 202323168900.0. The entire contents of the above application are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of battery technology, and in particular to a battery collection component and a battery pack. Background Art

[0003] In a battery pack, a CCS (Cells Contact System) is usually used to realize high-voltage series and parallel connection of battery cells, as well as temperature sampling and cell voltage sampling functions of the battery. The sampling signal will be transmitted to the BMS (Battery Management System) through a cable. The AFE (analog front end, also known as the battery sampling chip) module in the BMS processes it and converts it into a digital signal, which is then processed by the BMS. Currently, there are usually two ways to set up the CCS components of power batteries. One is to arrange the temperature sensing unit of the CCS component on the top of the battery cell. However, since a liquid cooling plate is usually set on the top of the battery cell, the temperature sensing unit cannot accurately collect the battery cell temperature. The second is to arrange the temperature sensing unit of the CCS component separately on the side of the battery cell. However, arranging the temperature sensing unit separately requires repositioning and gluing, which is difficult to install and has low efficiency. SUMMARY OF THE INVENTION

[0032] It should be noted that the present application does not limit the specific installation position of the matching portion 44 , which may be arranged at a peripheral position on the bracket 1 corresponding to the jack 41 , or may be arranged inside the jack 41 .

[0033] In one embodiment, a snap-fit ​​protrusion 431 is protruded from the side wall 42a of the latch 42 at a position close to the end 42b thereof, and a snap-fit ​​groove 441 communicating with the insertion hole 41 is provided at a position corresponding to the periphery of the insertion hole 41 of the bracket 1; wherein, the latch 42 is inserted into the insertion hole 41, and the snap-fit ​​protrusion 431 is snap-fitted and fixed in the snap-fit ​​groove 441; the snap-fit ​​portion 43 includes the snap-fit ​​protrusion 431; the mating portion 44 includes the snap-fit ​​groove 441; when the latch 42 is inserted into the insertion hole 41, the snap-fit ​​protrusion 431 is snap-fitted and fixed in the snap-fit ​​groove 441, thereby fixing the fixing base 2 relative to the bracket 1 in the up and down directions, thereby improving the installation stability of the fixing base 2 and the temperature measuring unit 3.

[0034] The present application does not limit the specific shape of the pin. The cross-section of the pin can be circular, square, or irregular, and the user can set it according to the actual product structure and needs.

[0035] In one embodiment, the latch is square in shape. This application does not limit the specific number of the fastening protrusions 431 and the fastening grooves 441. The fastening protrusions 431 may be one and correspondingly provided on one side wall 42a of the latch 42, or two and correspondingly provided on two side walls 42a of the latch 42, or three or four.

[0036] In one embodiment, the latch 42 has the locking protrusions 431 protruding from both side walls 42a in the first direction F1; the bracket 1 is correspondingly provided with two locking grooves 441; that is, in the first direction F1, the two side walls 42a of the latch 42 are relatively provided with two locking protrusions 431, so that the upper and lower limiting fixation of the latch 42 is more balanced and stable.

[0037] In order to make the connection between the socket 41 and the plug 42 smoother and faster, in one embodiment, a guide plate 45 is provided in the socket 41, and the guide plate 45 divides the socket 41 into a first socket 411 and a second socket 412; correspondingly, a guide groove 46 is provided at the end 42b of the plug 42, and the two side walls of the guide groove 46 in the first direction F1 are penetrated to separate the plug 42 into a first plug plate 421 and a second plug plate 422; the guide plate 45 is plugged into and matched with the guide groove 46, and the first plug plate 421 is inserted into the first socket 411, and the second plug plate 422 is inserted into the second socket 412. By providing the guide plate 45 and the guide groove 46, not only can the insertion of the socket 41 and the pin 42 be smoother and faster; but also, the first plug plate 421 and the first socket 411, the second plug plate 422 and the second socket 412 can be divided in the second direction F2, and the socket 41 and the pin 42 can be further limited in the second direction F2, thereby further improving the stability of the installation of the fixing base 2.

[0038] Specifically, in the first direction F1, a first snap-fitting protrusion 4311 is protruded from at least one side wall of the first plug-in plate 421, and a second snap-fitting protrusion 4312 is protruded from at least one side wall of the second plug-in plate 422; the end face of the guide plate 45 is flush with the periphery of the insertion hole 41; the bracket 1 is provided with a first snap-fitting groove 4411 at the periphery of the first insertion hole 411, and a second snap-fitting groove 4412 at the periphery of the second insertion hole 412; in the first direction F1, the side walls of the first snap-fitting groove 4411 and the second snap-fitting groove 4412 are both through-set, and the first snap-fitting groove 4411 and the second snap-fitting groove 4412 correspond to the positions of the first snap-fitting protrusion 4311 and the second snap-fitting protrusion 4312 respectively and are snap-fitted and fixed; wherein, in the second direction F2, one side surface of the guide plate 45 forms the side wall of the first snap-fitting groove 4411 and / or the second snap-fitting groove 4412.

[0039] By providing the first snap-fit ​​protrusion 4311 and first snap-fit ​​groove 4411, and the second snap-fit ​​protrusion 4312 and second snap-fit ​​groove 4412, the latch 42 can be fixed in an upward and downward position, thereby improving the installation stability of the fixing base 2. Furthermore, the first snap-fit ​​groove 4411 and the second snap-fit ​​groove 4412 are correspondingly provided at the periphery of the first insertion hole 411 and the periphery of the second insertion hole 412, and the first snap-fit ​​groove 4411 and the second snap-fit ​​groove 4412 are formed inwardly along a side surface of the guide plate 45. When the first snap-fit ​​groove 4411 and the second snap-fit ​​groove 4412 are respectively snap-fitted with the first snap-fit ​​protrusion 4311 and the second snap-fit ​​protrusion 4312, the space occupied by the first snap-fit ​​protrusion 4311 and the second snap-fit ​​protrusion 4312 is reduced, thereby making the connection between the fixing base 2 and the bracket 1 more compact and reducing the overall volume of the battery collection assembly 100.

[0040] In one embodiment, at least one groove 423 is formed at the end 42b of the latch 42. The two side walls of the groove 423 in the second direction F2 are penetrated and respectively penetrate the first plug plate 421 and the second plug plate 422. By providing the groove 423, the first plug plate 421 and the second plug plate 422 are hollowed out, which not only saves the material of the latch 42 and reduces the cost, but also reduces the weight of the latch 42.

[0041] In one embodiment, the fixing base 2 includes a mounting portion 23 and a connecting portion 24. The mounting portion 23 is disposed on the side 200b of the battery module 200 and extends vertically. The connecting portion 24 is disposed at the upper end 23a of the mounting portion 23 and extends toward the bracket 1. The battery collection assembly 100 also includes a detachable connecting structure 4 disposed between the lower surface of the connecting portion 24 and the upper surface 1a of the bracket 1. The first end 21 includes the upper end 23a of the mounting portion 23. The temperature measuring unit 3 is disposed on the mounting portion 23. The provision of the connecting portion 24 allows the fixing assembly to be detachably mounted on the upper surface of the bracket. The detachable connecting structure 4 is disposed between the lower surface of the connecting portion 24 and the upper surface 1a of the bracket 1. This reduces the overall vertical dimensions of the fixing base 2 and the bracket 1 after assembly, thereby reducing the vertical dimensions of the battery collection assembly 100.

[0042] Specifically, the detachable connection structure 4 includes a latch 42 provided on the lower surface of the connecting portion 24 and a socket 41 provided on the upper surface 1a of the bracket 1. The latch 42 plugs into and mates with the socket 41. A relief groove 12 is defined on the upper surface 1a of the bracket 1 at a position corresponding to the periphery of the socket 41. The relief groove 12 is provided near the mounting portion 23 and extends through the sidewall of the mounting portion 23. The latch 42 is inserted into the socket 41, and the connecting portion 24 is at least partially disposed within the relief groove 12. The relief groove 12 accommodates a portion of the connecting portion 24, thereby making the assembled structure of the fixing base 2 and the bracket 1 more compact, thereby reducing the overall volume of the battery collection assembly 100.

[0043] Please refer to Figures 2, 6 and 7. The fixing base 2 has a first side surface 25 facing the battery module 200, and a second side surface 26 opposite to the first side surface 25. The fixing base 2 has a second end 22 away from the bracket; the first side surface 25 is provided with a mounting groove 251 at a position close to the second end portion 22, and the mounting groove 251 is provided for the temperature measuring unit 3 to be placed; the second side surface 26 is provided with a second wiring groove 261, and the second wiring groove 261 is connected to the mounting groove 251 through a wire hole 252, so that the connecting wire 31 of the temperature measuring unit 3 is passed from the wire hole 252 to the second wiring groove 261, and the second wiring groove 261 is penetrated through the side wall facing the first end portion 21, so that the connecting wire 31 of the temperature measuring unit 3 extends from the second wiring groove 261 to the first wiring groove 11.

[0044] During the installation process, the temperature measuring unit 3 is placed in the installation groove 251, and the connecting wire 31 of the temperature measuring unit 3 is passed through the wire hole 252, so that the connecting wire 31 of the temperature measuring unit 3 is wrapped around the second side surface 26 and placed in the second wiring groove 261. The connecting wire 31 of the temperature measuring unit 3 extends to the first wiring groove 11 through the second wiring groove 261; in this way, not only the routing of the connecting wire 31 of the temperature measuring unit 3 on the fixing seat 2 is more reasonable, but also the connection of the connecting wire 31 of the temperature measuring unit 3 from the fixing seat 2 to the first wiring groove 11 can be facilitated.

[0045] Specifically, further referring to Figure 7, a concave-convex structure 27 is formed on the bottom wall of the second wiring groove 261, so that the connecting line 31 of the temperature measuring unit 3 extends along the concave-convex structure 27, and a pressure plate 28 is provided at the notch of the second wiring groove 261. The pressure plate 28 corresponds to the position of the wire hole 252, and the pressure plate 28 is provided corresponding to the concave portion 27a of the concave-convex structure 27 to suppress and limit the connecting line 31 in the concave portion 27a of the concave-convex structure 27; through the cooperation of the concave-convex structure 27 and the pressure plate 28, the alternating fixation of the connecting line 31 is achieved, thereby improving the installation stability of the connecting line 31 of the temperature measuring unit 3.

[0046] To facilitate the installation of the connecting wire 31, in one embodiment, referring to FIG8 , an installation gap 29 is formed between the pressing plate 28 and the two opposite side walls of the wire-passing hole 252.

The pressing plate 28 is provided at the notch of the second wiring groove 261 to press and fix the connecting wire 31 in the wire-passing hole 252. At the same time, since the installation gap 29 is formed between the pressing plate 28 and the two opposite side walls of the wire-passing hole 252, the presence of the installation gap 29 not only facilitates the connecting wire 31 to pass through the wire-passing hole 252, but also facilitates the user to adjust the shape and extension direction of the connecting wire 31 passing through the wire-passing hole 252, thereby making the installation of the connecting wire 31 more convenient.
