[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0033] The composite adapter sheet 100 according to the embodiment of the utility model is first described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 3 As shown, the composite adapter 100 according to the embodiment of the present utility model includes: an adapter body.

[0035] Specifically, the adapter body includes a first functional segment 10 and a second functional segment 20. The first functional segment 10 is made of a first material and is suitable for welding with a first component of a battery. The second functional segment 20 is made of a second material and is suitable for welding with a second component of a battery. One end of the first functional segment 10 blends with one end of the second functional segment 20 to form a blending segment 30 connecting each other.

[0036] In other words, if Figures 1 to 3As shown, the composite adapter sheet 100 according to the embodiment of the utility model mainly includes an adapter sheet body, and the adapter sheet body mainly includes a first functional segment 10 and a second functional segment 20, wherein the first functional segment 10 is a first material, and the first material is the same as the material of the welding surface of the first component of the battery, so as to facilitate welding the first functional segment 10 and the first component of the battery together; the second functional segment 20 is a second material, and the second material is the same as the material of the welding surface of the second component of the battery, so as to facilitate welding the second functional segment 20 and the second component of the battery together.

[0037] It should be noted that the first component may be a pole or a lug of a battery, the second component may be a lug or a pole of a battery, the first component and the second component may also be other components of the battery, which may be determined according to actual needs.

[0038] like Figure 2 and Figure 3 As shown, during manufacturing, the first end of the first functional segment 10 can be brought into contact with the first end of the second functional segment 20, and the first end of the first functional segment 10 and the first end of the second functional segment 20 can be heated to a molten state, and the height of the one with a larger density can be higher than the one with a smaller density. For example, when the density of the first material is greater than the density of the second material, the height of the first functional segment 10 can be higher than the height of the second functional segment 20, so that when the first end of the first functional segment 10 and the first end of the second functional segment 20 are in a molten state, the first material and the second material are blended, and after cooling, a blending segment 30 can be formed, and the blending segment 30 can reliably connect the first functional segment 10 and the second functional segment 20 together.

[0039] Therefore, according to the composite adapter sheet 100 provided in this embodiment, the first functional segment 10 and the second functional segment 20 can be connected together through the fusion segment 30 formed by the fusion of the first functional segment 10 and the second functional segment 20. Compared with the prior art, the structure of the composite adapter sheet 100 can be effectively simplified, which is convenient for production and manufacturing, and the connection effect is good, which can ensure the performance of the battery.

[0040] In some embodiments of the present invention, the density of the first material is greater than that of the second material, the first functional segment 10 and the second functional segment 20 are distributed along the first direction, and the size of the first functional segment 10 in the first direction is smaller than the size of the second functional segment 20 in the first direction.

[0041] In other words, in order to prevent the composite adapter sheet 100 from being too heavy, the sizes of the first functional segment 10 and the second functional segment 20 may be set according to their densities.

[0042] Specifically, Figure 2 and Figure 3As shown, the first functional segment 10 and the second functional segment 20 can be distributed along the first direction, and the first direction can be the length direction of the composite adapter 100. The dimension of the first functional segment 10 in the first direction is d1, and the dimension of the second functional segment 20 in the first direction is d2. When the density of the first material is greater than the density of the second material, d1<d2, thereby effectively avoiding the excessive weight of the composite adapter 100, thereby avoiding the excessive weight of the battery affecting the performance of the electrical equipment.

[0043] According to an embodiment of the present invention, the adapter body includes a plurality of first functional segments 10 , and the plurality of first functional segments 10 are spaced apart along the second direction.

[0045] In this embodiment, multiple first functional segments 10 can be welded to multiple first components of the battery. When the first component is a pole, the composite adapter 100 can be suitable for batteries with multiple groups of poles, and is conducive to the layout of the first functional segment 10 and the second functional segment 20, so as to facilitate setting the weight of the adapter body to a smaller range.

[0046] In some embodiments of the present invention, the first functional section 10 is provided with a plurality of first welding portions 11 extending along the first direction, the first welding portions 11 are suitable for being welded to the first component, and the plurality of first welding portions 11 are spaced apart along the second direction.

[0047] Specifically, a plurality of first welding portions 11 extending along the first direction are provided at one end of the first functional segment 10 away from the second functional segment 20. During manufacturing, one or more notches can be processed at one end of the first functional segment 10 away from the second functional segment 20 using a cutting device, and a plurality of first welding portions 11 distributed along the second direction can be formed at one end of the first functional segment 10 away from the second functional segment 20 through the notches, so that the composite adapter 100 can be welded to a plurality of first components of the battery, and when the first component is a pole, the composite adapter 100 can be welded to a plurality of positive poles or negative poles of the battery, so that the composite adapter 100 can be applied to batteries with multiple sets of poles.

[0048] According to an embodiment of the present invention, the second functional section 20 is provided with a plurality of second welding portions 21 extending along the first direction, the second welding portions 21 are suitable for being welded to the second component, and the plurality of second welding portions 21 are spaced apart along the second direction.

[0050] In some embodiments of the present invention, the first functional section 10 is provided with a first welding portion 11 extending along the first direction, and the width of the first welding portion 11 is greater than the width of each second welding portion 21 .

[0051] That is to say, Figure 1 and Figure 2 As shown, a portion of the first functional segment 10 away from the second functional segment 20 can be formed as a first welding portion 11. When in use, the first welding portion 11 is suitable for welding with the first member on one side in the thickness direction thereof. In the case where the second functional segment 20 is provided with a plurality of second welding portions 21, the width of the first welding portion 11 is greater than the width of each second welding portion 21, so that the current flow capacity of the first welding portion 11 can be ensured, thereby ensuring the performance of the battery.

[0053] Specifically, the first component may be a positive electrode post or a negative electrode post of a battery, and the second component may be a positive electrode lug or a negative electrode lug of the battery.

[0054] In some embodiments of the present invention, the adapter plate body is formed as a strip-shaped plate extending along the first direction.

[0055] In detail, during production, the adapter sheet body can be manufactured as a strip-shaped sheet extending along the first direction. The strip-shaped sheet structure is suitable for most batteries and is conducive to production.
