[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following is for reference. Figures 1-6 Description of a sampling component 100 for a battery according to an embodiment of the present invention.

[0036] like Figures 1-6 As shown, the sampling component 100 for a battery according to an embodiment of the present invention includes: a PCB board 10 and a sampling sheet 30.

[0037] The PCB board 10 has a fuse 11, which is adapted to be electrically connected to the sampling harness 20 of the battery; the sampling chip 30 is electrically connected to the fuse 11 and adapted to be electrically connected to the battery cell.

[0038] It should be noted that the PCB board 10 mentioned below refers to Printed Circuit Board, and will not be described again below.

[0039] As some embodiments of this application, the battery cell has terminals, the PCB board 10 has wire harness pads 40 and sampling pads 31, the sampling pads 30 can be electrically connected to the terminals by soldering, or the sampling pads 30 and the terminals can be electrically connected by other components, the fuse 11 is etched on the PCB board 10, the sampling pads 30 are electrically connected to the sampling pads 31, the sampling pads 31 are electrically connected to the fuse 11, the fuse 11 is electrically connected to the wire harness pads 40, and the wire harness pads 40 are electrically connected to the sampling wire harness 20, so that the terminals of the battery cell are electrically connected to the sampling wire harness 20, and the sampling wire harness 20 is electrically connected to the battery controller, the battery controller can be configured as a BMS (BATTERY MANAGEMENT SYSTEM).

[0040] The sampling sheet 30 can be made of, but is not limited to, copper, nickel, etc. As some embodiments of this application, the sampling sheet 30 is constructed as a nickel sheet. As some embodiments of this application, such as... Figure 1 As shown, the surface of the sampling piece 30 has an observation port 14, through which the weld joint can be observed to see whether it meets the requirements.

[0041] It should be noted that the PCB board 10 has low material cost and can only serve as a carrier for the fuse 11. Long-distance transmission of voltage, temperature signals, etc. can be achieved through the sampling harness 20. The sampling harness 20 can be constructed as a wire harness or an FFC (Flexible Flat Cable). This configuration can effectively save etching area, simplify the process flow of the PCB board 10, improve the production efficiency of the sampling component 100, and reduce the cost of the sampling component 100.

[0042] It should be noted that the fuse 11 serves as overcurrent protection. The battery sampling harness 20 is responsible for transmitting the electrical signals collected from the battery cell. During the charging and discharging process, the current in the sampling harness 20 may increase abnormally due to issues such as battery cell failure or external short circuit. At this time, the fuse 11, which is electrically connected to the sampling harness 20, can quickly melt and reduce the risk of a large current passing through the sampling harness 20 and the PCB board 10, thereby protecting the battery cell, sampling chip 30, sampling harness 20, and BMS.

[0043] Therefore, by using a PCB board 10 (Printed Circuit Board) for the sampling component 100 in the battery, compared with the technical solution using an FPC (Flexible Printed Circuit Board), the process flow can be simplified, the production cycle can be shortened, and the cost of the sampling component 100 can be reduced. By electrically connecting the fuse 11 to the battery's sampling harness 20, and electrically connecting the sampling piece 30 to the fuse 11 and to the battery cell, the sampling component 100 can automatically melt and break when short-circuited or when the current is too high, which helps to improve the safety of the sampling component 100.

[0044] In some embodiments of this utility model, such as Figures 1-5 As shown, the PCB board 10 has a sampling pad 31, the sampling pad 30 is soldered to the sampling pad 31, and one end of the fuse 11 is electrically connected to the sampling pad 31.

[0045] Among them, such as Figures 2-5 As shown, the sampling pad 31 is soldered to the PCB board 10. In some embodiments of this application, the sampling pad 31 and the PCB board 10 can be soldered together by gold finger soldering. Alternatively, in some embodiments of this application, the sampling pad 30 and the sampling pad 31 can be soldered together by through-hole soldering. The fuse 11 has two opposite ends, one end of which is electrically connected to the sampling pad 31 and the other end is electrically connected to the wire harness pad 40.

[0046] By providing the PCB board 10 with sampling pads 31, the sampling pads 30 can be easily connected to the PCB board 10 via the sampling pads 31, thereby enabling a stable electrical connection between the battery cell and the PCB board 10. This is beneficial for improving the accuracy of the sampling assembly 100. Furthermore, this arrangement reduces the difficulty of connecting the fuse 11 to the sampling pads 30, thereby improving the production efficiency of the sampling assembly 100.

[0047] In some embodiments of this utility model, such as Figures 1-5 As shown, the PCB board 10 has a wire harness pad 40, and the other end of the fuse 11 is electrically connected to the wire harness pad 40.

[0048] As some embodiments of this application, such as Figure 2 and Figure 3 As shown, the wire harness pads 40 and the PCB board 10 are soldered together using gold finger soldering. This is one of the embodiments of this application. Figure 4 and Figure 5As shown, the wire harness pad 40 is soldered to the PCB board 10 via through-hole soldering. The fuse 11 has two opposing ends, one of which is electrically connected to the sampling pad 31, and the other end is electrically connected to the wire harness pad 40. In some embodiments of this application, the fuse 11 is connected to the sampling pad 31 by soldering, and in some embodiments of this application, the fuse 11 is connected to the wire harness pad 40 by soldering.

[0049] By providing the PCB board 10 with wire harness pads 40, the sampling wire harness 20 can be easily electrically connected to the PCB board 10, and the fuse 11 can be connected between the sampling wire harness 20 and the sampling plate 30. When the battery sampling assembly 100 is working, the electrical signal of the battery cell is transmitted to the sampling wire harness 20 through the sampling plate 30 and the PCB board 10, providing a stable transmission path for the electrical signal and ensuring that the sampling assembly 100 can obtain accurate information about the battery cell in real time, thereby enabling precise monitoring of the battery status. In addition, the wire harness pads 40 also provide reliable mechanical fixing points for the sampling wire harness 20, fixing its position on the PCB board 10 and improving the reliability of the sampling assembly 100.

[0050] In some embodiments of this utility model, such as Figures 2-5 As shown, the sampling pad 31 includes a first pad body 32 and a plurality of first connecting parts 33. The first connecting parts 33 are connected to the first pad body 32 and are electrically connected to at least one fuse 11.

[0051] In this embodiment, the first connecting portion 33 is connected to the first pad body 32. As some embodiments of this application, the connection method between the first connecting portion 33 and the first pad body 32 can be, but is not limited to, welding, bolting, etc. As some embodiments of this application, the first connecting portion 33 and the first pad body 32 are integrally formed. There can be multiple first connecting portions 33, including, but not limited to, two, three, four, etc. As some embodiments of this application, such as... Figure 2 As shown, the three first connecting parts 33 are integrally formed with the first pad body 32.

[0052] In some embodiments of this application, the first connecting portion 33 is electrically connected to one fuse 11; in some embodiments of this application, the first connecting portion 33 is electrically connected to multiple fuses 11. In some embodiments of this application, among the multiple first connecting portions 33, some first connecting portions 33 are electrically connected to one fuse 11 respectively, and other first connecting portions 33 are electrically connected to multiple fuses 11 respectively.

[0053] By including a first pad body 32 and multiple first connecting portions 33 in the sampling pad 31, it is easy to connect the sampling pad 31 to multiple fuses 11, reducing the manufacturing difficulty of the sampling component 100. Moreover, it can form overcurrent protection on the PCB board 10, which is beneficial to improving the safety performance of the sampling component 100.

[0054] In some embodiments of this utility model, such as Figures 2-5 As shown, there are multiple wire harness pads 40, and at least one wire harness pad 40 includes a second pad body 41 and a second connecting part 42. The second connecting part 42 is connected to the second pad body 41 and is electrically connected to the fuse 11.

[0055] The number of wire harness pads 40 is multiple, and the number of wire harness pads 40 can be, but is not limited to, two, three, four, etc. As some embodiments of this application, at least one wire harness pad 40 includes a second pad body 41 and a second connecting portion 42. For example, all wire harness pads 40 include a second pad body 41 and a second connecting portion 42, or some wire harness pads 40 include a second pad body 41 and a second connecting portion 42. As some embodiments of this application, such as... Figure 2 and Figure 4 As shown, there are four wire harness pads 40, two of which include a second pad body 41 and a second connection portion 42.

[0056] The second connecting part 42 is connected to the second pad body 41. The connection between the second connecting part 42 and the second pad body 41 can be, but is not limited to, welding, bolt connection, etc. As some embodiments of this application, the second connecting part 42 and the second pad body 41 are connected by welding. As some embodiments of this application, the second connecting part 42 and the second pad body 41 are integrally formed.

[0057] By including at least one wire harness pad 40 with a second pad body 41 and a second connection portion 42, it is easy to electrically connect the fuse 11 to the wire harness pad 40, thereby facilitating the connection of the fuse 11 between the sampling wire harness 20 and the sampling piece 30, which helps to reduce the manufacturing difficulty of the sampling assembly 100.

[0058] In some embodiments of this utility model, such as Figures 1-5 As shown, there are multiple fuses 11 and multiple wire harness pads 40, with each fuse 11 and wire harness pad 40 corresponding to the other.

[0059] As some embodiments of this application, such as Figure 2 and Figure 4As shown, there are four fuses 11 and four wire harness pads 40. The four fuses 11 and the four wire harness pads 40 are set in a one-to-one correspondence. The four fuses 11 are respectively connected between the sampling pad 31 and the corresponding wire harness pad 40.

[0060] As some embodiments of this application, such as Figure 3 and Figure 5 As shown, there are two fuses 11 and two wire harness pads 40. The two fuses 11 and the two wire harness pads 40 are set in a one-to-one correspondence. The two fuses 11 are respectively connected between the sampling pad 31 and the corresponding wire harness pad 40.

[0061] This configuration allows each fuse 11 to correspond to a wire harness pad 40, thereby enabling each fuse 11 to correspond to a sampling wire harness 20. This provides precise overcurrent protection for the corresponding circuits. Furthermore, by configuring multiple fuses 11 and multiple wire harness pads 40 in a one-to-one correspondence, the occurrence of a fuse blowout will not affect other circuits, which helps to improve the reliability of the sampling component 100.

[0062] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the wire harness pad 40 has a first through hole 43, and the PCB board 10 has a second through hole 12, with the first through hole 43 corresponding to the second through hole 12.

[0063] As some embodiments of this application, such as Figure 5 As shown, there are two wire harness pads 40. Each wire harness pad 40 has a first through hole 43 and a second through hole 12 formed on the PCB board 10. The number of first through holes 43 and second through holes 12 are the same and they are set one-to-one so that the two wire harness pads 40 are soldered to the PCB board 10 by through hole soldering.

[0064] As some embodiments of this application, such as Figure 4 As shown, there are four wire harness pads 40, two of which include a second pad body 41 and a second connecting part 42, and the other two wire harness pads 40 include a second pad body 41. Each second pad body 41 has a first through hole 43 and a second through hole 12 formed on the PCB board 10. The number of first through holes 43 and second through holes 12 are the same and they are set one-to-one, so that the four wire harness pads 40 are soldered to the PCB board 10 by through-hole soldering.

[0065] This configuration allows the wire harness pad 40 to be soldered to the PCB board 10 via through-hole soldering, which helps reduce the difficulty of connecting the wire harness pad 40 to the PCB board 10, improves production efficiency, and reduces product weight, which is beneficial for the lightweight design of the sampling component 100.

[0066] In some embodiments of this utility model, such as Figures 1-5 As shown, at least a portion of the structure of the fuse 11 is constructed as an arc segment.

[0067] In some embodiments of this application, a portion of the fuse 11 is constructed as an arc segment; in some embodiments of this application, the entire structure of the fuse 11 is constructed as an arc segment. In some embodiments of this application, the line width of the fuse 11 may be, but is not limited to, 0.15 mm; the fusing current of the fuse 11 may be, but is not limited to, 8 A; and the maximum current carrying time of the fuse 11 may be, but is not limited to, 3 seconds.

[0068] By constructing at least a portion of the structure of the fuse 11 as an arc segment, the length of the fuse 11 can be increased within a limited installation area, thereby improving the reliability of the fuse 11 and thus enhancing the safety of the sampling assembly 100.

[0069] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the PCB board 10 has at least one positioning groove 13.

[0070] As some embodiments of this application, the PCB board 10 has a positioning groove 13. As some embodiments of this application, the PCB board 10 has multiple positioning grooves 13. For example, the PCB board 10 has two positioning grooves 13, which are disposed at opposite ends of the PCB board 10. By having at least one positioning groove 13 on the PCB board 10, the mounting position of the PCB board 10 can be quickly determined, which facilitates fixing the PCB board 10 and helps to reduce the installation difficulty of the sampling component 100.

[0071] According to the sampling assembly of the present utility model embodiment, such as Figure 1 As shown, it includes: an isolation plate 50, a connecting strip 54, a sampling assembly 100, and a sampling harness 20. The sampling assembly 100 is the aforementioned sampling assembly 100 for the battery. The sampling assembly 100 is disposed on the isolation plate 50. The connecting strip 54 is connected between the battery cell and the sampling piece 30. The sampling harness 20 is electrically connected to the fuse 11 and is adapted to be electrically connected to the battery controller.

[0072] The sampling component 100 is disposed on the isolation plate 50. In some embodiments of this application, the sampling component 100 and the isolation plate 50 are connected by bolts. In other embodiments, the sampling component 100 and the isolation plate 50 are connected by riveting. The connecting strip 54 is connected between the battery cell and the sampling piece 30. The material of the connecting strip 54 can be, but is not limited to, conductive materials such as copper and aluminum.

[0073] Specifically, the connector 54 is connected between the terminal of the battery cell and the sampling piece 30. The sampling piece 30 is electrically connected to the sampling piece pad 31 of the PCB board 10. The fuse 11 is connected between the sampling piece pad 31 and the wire harness pad 40. The wire harness pad 40 is electrically connected to the sampling wire harness 20. The sampling wire harness 20 can be electrically connected to the controller to transmit electrical signals to the controller.

[0074] As some embodiments of this application, the isolation plate 50 includes a plate body 51 and an assembly 52. ​​The assembly 52 is disposed on the plate body 51 and defines an assembly groove 55. The assembly groove 55 is along a first direction (i.e., Figure 1 As shown in direction A, the sampling harness 20 can be inserted into the assembly 52 along the first direction, and part of the structure of the sampling harness 20 is assembled in the assembly slot 55.

[0075] The isolation plate 50 may be, but is not limited to, made of plastic (PC), rubber, etc. Along the height direction of the sampling assembly, one end of the mounting component 52 is fixed to the plate body 51. In some embodiments of this application, the plate body 51 and the mounting component 52 are integrally formed. In some embodiments of this application, the plate body 51 and the mounting component 52 are bonded together. The end of the mounting component 52 facing away from the plate body 51 is open, so that the mounting component 52 defines an assembly groove 55. The assembly groove 55 can provide an assembly position for the sampling harness 20. Furthermore, the mounting component 52 has a simple structure, which helps to reduce the assembly difficulty of the sampling harness 20 and improve the assembly efficiency and economic efficiency of the sampling assembly. Along the first direction (i.e.... Figure 1 As shown in direction A), the mounting slot 55 penetrates the assembly 52 so that at least a portion of the sampling harness 20 can be smoothly mounted from the open end of the mounting slot 55 into the mounting slot 55, and along the first direction (i.e. Figure 1 (As shown in direction A) can be moved.

[0076] As some embodiments of this application, the number of assembly 52 is multiple, and the number of assembly 52 can be, but is not limited to, two, three, four, etc. As some embodiments of this application, the number of assembly 52 is a fifth.

[0077] As some embodiments of this application, the assembly 52 includes two mounting portions 53, which are spaced apart and correspondingly arranged to define the assembly groove 55. This can be understood as the two mounting portions 53 being spaced apart and symmetrically arranged to define the assembly groove 55.

[0078] Two mounting portions 53 are spaced apart and correspondingly arranged to define a first direction (i.e., ...) between the two mounting portions 53. Figure 1The assembly slot 55 (as shown in direction A) penetrates the assembly 52. ​​This arrangement makes the forming method of the assembly slot 55 reasonable, reduces the forming difficulty of the assembly slot 55, and has a simple structure, which helps to reduce the assembly difficulty of assembling the sampling harness 20 into the assembly slot 55 and improves the assembly efficiency of the sampling harness 20.

[0079] As some embodiments of this application, such as Figure 6 As shown, the mounting part 53 includes a first sub-part 531 and a second sub-part 532. The second sub-part 532 is connected between the first sub-part 531 and the plate body 51. The distance between the two second sub-parts 532 of the mounting part 52 is greater than the distance between the two first sub-parts 531.

[0080] The first sub-part 531 and the second sub-part 532 can be connected, but are not limited to, by integral molding or bonding. The second sub-part 532 is connected between the corresponding first sub-part 531 and the plate body 51. The interval between the two second sub-parts 532 is greater than the interval between the two first sub-parts 531. This arrangement allows the sampling harness 20 to be reliably engaged in the assembly slot 55 and to move along the first direction (i.e., within the assembly slot 55) within the first direction. Figure 1 (As shown in direction A) can be moved.

[0081] Specifically, the sampling harness 20 is aligned with the open end of the assembly slot 55. During assembly, the sampling harness 20 first drives the two first sub-parts 531 to move in a direction away from each other, so that the harness can be smoothly engaged between the two second sub-parts 532. After the harness has completely passed through the first sub-parts 531, the first sub-parts 531 move towards each other under the elastic force of the mounting part 53, so that the mounting part 53 returns to its initial state. Since the distance between the two second sub-parts 532 is greater than the distance between the two first sub-parts 531, the two first sub-parts 531 can restrict the sampling harness 20 from moving out of the assembly slot 55 from the open end of the assembly slot 55, thereby realizing that the sampling harness 20 moves along the first direction (i.e., ...) within the assembly slot 55. Figure 1 The sampling harness 20 can be moved in the direction shown in A without moving out of the assembly slot 55, thereby improving the relative reliability and working stability of the sampling harness 20 position.

[0082] The battery according to the present invention includes the sampling assembly of the above embodiments. By using a PCB board 10 (Printed Circuit Board) for the sampling component 100 in the battery, compared with the technical solution of using an FPC (Flexible Printed Circuit Board), the process flow can be simplified, the production cycle can be shortened, and the cost of the sampling component 100 can be reduced. By electrically connecting the fuse 11 to the sampling harness 20 of the battery, and electrically connecting the sampling piece 30 to the fuse 11 and to the battery cell, the sampling component 100 can be automatically melted when short-circuited, which is beneficial to improving the safety of the sampling component 100.
