[0031] It can be understood that the connecting piece 10, the sampling plate 20 and the supporting member 30 constitute the main structure of the battery sampler 100, and the sampling plate 20 and the connecting piece 10 are electrically connected, so that the sampling plate 20 and the connecting piece 10 can be pre-installed, thereby saving the assembly process of the battery sampler 100, and the first fixing portion 31 and the second fixing portion 32 are arranged on one side of the supporting member 30, so that the supporting member 30 can provide an installation position for other components, and the first fixing portion 31 and the second fixing portion 32 are arranged at intervals, so that the first fixing portion 31 and the second fixing portion 32 do not affect each other, the connecting piece 10 is fixedly connected to the first fixing portion 31, so that the connecting piece 10 and the supporting member 30 are connected, and the sampling plate 20 is fixedly connected to the second fixing portion 32, so that the sampling plate 20 and the supporting member 30 are connected. This arrangement facilitates the installation of the connecting piece 10 and the sampling plate 20 on the supporting member 30, thereby saving the installation steps of the connecting piece 10 and the sampling plate 20, and thereby improving the assembly efficiency of the battery sampler 100.

[0032] Specifically, according to the arrangement of the battery cells 200 in the battery pack, multiple sampling plates 20 can be used, thereby meeting the sampling requirements of the battery sampler 100 for the battery pack.

[0033] Therefore, by providing the first fixing portion 31 and the second fixing portion 32 on the carrier 30, it is convenient to fix the connecting piece 10 on the first fixing portion 31, and the sampling plate 20 on the second fixing portion 32. This arrangement facilitates the fixing of the connecting piece 10 on the carrier 30, and the fixing of the sampling plate 20 on the carrier 30, thereby saving the installation process of the battery pack, facilitating installation and disassembly, and not affecting the connection stability during the transportation of the battery pack.

[0034] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, a first connecting portion 11 is provided on the connecting sheet 10 , and a second connecting portion 21 is provided on the sampling plate 20 . The first connecting portion 11 is fixedly connected to the first fixing portion 31 , and the second connecting portion 21 is fixedly connected to the second fixing portion 32 .

[0035] In this way, the first connecting portion 11 is located on one side of the connecting piece 10, and the first connecting portion 11 is arranged toward the supporting member 30, so that the first connecting portion 11 and the first fixing portion 31 can be connected correspondingly, and then the connecting piece 10 and the supporting member 30 can be fastened and connected. The second connecting portion 21 is located on one side of the sampling plate 20, and the second connecting portion 21 is arranged toward the supporting member 30, so that the second connecting portion 21 and the second fixing portion 32 can be connected correspondingly, and then the sampling plate 20 and the supporting member 30 can be fastened and connected. In this way, the connecting piece 10, the sampling plate 20 and the supporting member 30 can be fastened and connected without adding other components, thereby ensuring the function of the battery sampler 100, and avoiding other components from occupying the space of the battery sampler 100, thereby improving the assembly efficiency of the battery sampler 100 and saving material costs.

[0036] Alternatively, if Figure 1-Figure 3 As shown, the first fixing portion 31 is configured as at least one of a hot rivet stud and a buckle, and the second fixing portion 32 is configured as at least one of a hot rivet stud and a buckle.

[0037] It should be noted that the first fixing portion 31 and the second fixing portion 32 may be selected from hot riveting posts or buckles, which can be more tightly connected to the first connecting portion 11 and the second connecting portion 21, thereby saving the installation space between the connecting piece 10, the sampling plate 20 and the carrier 30, as well as the assembly time of the connecting piece 10, the sampling plate 20 and the carrier 30, thereby improving the assembly efficiency of the battery sampler 100. For example, the hot riveting posts facilitate the softening and plasticity of the first fixing portion 31 and the second fixing portion 32.

[0038] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the sampling plate 20 includes: a first connecting piece 22 and a second connecting piece 23 , the first connecting piece 22 is fixedly connected to the carrier 30 , the second connecting piece 23 is electrically connected to the first connecting piece 22 , and the second connecting piece 23 is electrically connected to the connecting piece 10 .

[0039] It can be understood that the first connecting piece 22 extends along the length direction of the carrier 30, so as to increase the connection area between the first connecting piece 22 and the carrier 30, the second connecting portion 21 is located on the first connecting piece 22, so that the first connecting piece 22 can be connected to the carrier 30, the second connecting piece 23 is located on one side of the first connecting piece 22, and the second connecting piece 23 is connected to the connecting piece 10, so that the sampling plate 20 and the connecting piece 10 can be connected, and the connecting piece 10 is connected between the positive and negative poles of two adjacent battery cells 200, so that the first connecting piece 22 can sample the poles of the battery cells 200.

[0040] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the sampling plate 20 further includes: a third connecting piece 24, the third connecting piece 24 is connected to the first connecting piece 22, and the third connecting piece 24 is suitable for transmitting voltage.

[0041] That is, the third connecting piece 24 is located on the other side of the first connecting piece 22 and is connected to the first connecting piece 22 . The third connecting piece 24 is away from the carrier 30 , so that the third connecting piece can transfer voltage to the cell housing.

[0042] For example, an etching circuit is disposed inside the sampling plate 20 , and the etching circuit is connected to the second connecting piece 23 and the third connecting piece 24 , so that a fuse can be formed in the circuit, thereby improving the stability of the battery sampler 100 .

[0043] Alternatively, if Figure 1-Figure 3 As shown, the connecting piece 10 is connected to the first fixing portion 31 by welding, bolting, riveting or bonding; the sampling plate 20 is connected to the second fixing portion 32 by welding, bolting, riveting or bonding.

[0044] Such connection can save the connection steps between the connecting piece 10 and the first fixing part 31, and between the sampling plate 20 and the second fixing part 32, thereby improving the assembly efficiency between the connecting piece 10, the sampling plate 20 and the carrier 30, and further saving the installation process of the battery pack.

[0045] In some specific embodiments of the present invention, the carrier 30 is a plastic sheet structure, and the sampling plate 20 is one of a flexible circuit board and a printed circuit board.

[0046] It can be understood that the plastic sheet structure can be slightly deformed and has a relatively light weight. When there is a front-to-back difference in the battery cell 200 pole within the tolerance range, the carrier 30 is slightly deformed, so that the connecting piece 10 can fit more closely to the battery cell pole, and the connection stability between the connecting piece 10 and the carrier 30 can be ensured, thereby ensuring the performance of the battery sampler 100. The flexible circuit board is composed of an insulating film, a conductor and an adhesive, so as to ensure the reliability of the sampling plate 20. Moreover, the flexible circuit board has the characteristics of high wiring density, light weight, thin thickness, good bending properties, etc., which facilitates the installation of the sampling plate 20. In addition, a printed circuit board can also be used.

[0047] In some specific embodiments of the present invention, Figure 2 As shown, the carrier 30 is provided with a through hole 33, which is suitable for the battery pole to pass through, so that the connecting piece 10 can be installed. In other words, the through hole 33 is located on the carrier 30, and the through holes 33 are evenly spaced along the length direction of the carrier 30, so that the battery pole can pass through the through hole 33, and then the carrier 30 provides a mounting position for the connecting piece 10.

[0048] According to the battery pack of the utility model, it includes: a battery and the battery sampler 100 of the above embodiment. By setting the first fixing part 31 and the second fixing part 32 on the carrier 30, it is convenient to fix the connecting piece 10 on the first fixing part 31, and the sampling plate 20 on the second fixing part 32. This arrangement makes it convenient for the connecting piece 10 to be fixed on the carrier 30, and the sampling plate 20 to be fixed on the carrier 30, thereby saving the installation process of the battery pack, facilitating installation and disassembly, and not affecting the connection stability during the transportation of the battery pack.

[0049] Among them, Figure 1-Figure 3 As shown, the sampling plate 20 includes: a third connecting piece 24, and the third connecting piece 24 is used to connect with the battery shell. Such a configuration enables the third connecting piece 24 to collect the voltage of the battery, thereby facilitating the management and control of the battery pack.
