[0028] Figure 1 1 is a front view showing a substrate holder of a battery according to an embodiment of the present invention. Figure 2 This is a side view showing a substrate holder of a battery according to an embodiment of the present invention.

[0029] like Figure 1 and Figure 2 As shown, the substrate support 1 of the battery of the utility model comprises a support body 11 and fins 12. The support body 11 has a substrate storage portion 111 for storing the substrate and support legs 112. The substrate storage portion 111 is a hollow flat plate structure for storing the substrate of the battery. The support legs 112 are located at both ends below the substrate storage portion 111 ( Figure 1 The two sides of the flat substrate storage portion 111 ( Figure 1 The front and back sides of the paper, Figure 2 The left and right sides of the substrate receiving portion 111 are provided with a set of fins 12, respectively. Preferably, two sets of fins 12 are symmetrically arranged across the substrate receiving portion 111. Each set of fins 12 includes a plurality of fins 12 extending along the length direction of the substrate receiving portion 111 ( Figure 1 A plurality of fins 12 are arranged in a left-right direction (in the left-right direction) and are perpendicular to the surface of the substrate storage portion 111, and the bottom surface of the fin 12 is coplanar with the lower surface of the substrate storage portion 111.

[0030] In this embodiment, if Figure 1 As shown, each group of fins 12 includes 9 fins, but the number is not limited to this. Figure 2As shown, in the present embodiment, the fin 12 is in the shape of a thin plate in the form of a right-angled trapezoid, wherein the lower base of the right-angled trapezoid overlaps with the surface of the substrate storage portion 111, the upper base of the right-angled trapezoid is parallel to the surface of the substrate storage portion 111, and the waist of the right-angled trapezoid perpendicular to the upper and lower bases is perpendicular to the surface of the substrate storage portion 111 and is coplanar with the bottom surface of the substrate storage portion 111.

[0031] Next, the width of the upper surface of the substrate storage portion 111, that is, Figure 2 The width W1 shown is called the minimum width of the substrate holder, which is the sum of the width of the fin 12 and the width of the lower surface of the substrate storage portion 111, that is, Figure 2 The width W2 shown is referred to as the maximum width of the substrate holder. Since the fin 12 is formed in a thin sheet shape, it can be easily cut off a part or completely removed from the substrate storage portion 111, so that the substrate holder 1 becomes Figure 3 In order to facilitate the cutting operation of the fin, a cut, a thin-walled portion or a shallow groove may be formed in advance on the fin 12 .

[0032] Next, refer to Figure 4 , Figure 5 and Figure 6 , describing the structure of a battery using the substrate support of the present invention. Figure 4 1 is an exploded perspective view showing a battery using a battery holder according to an embodiment of the present invention. Figure 5 1 is a perspective view showing a battery after being assembled using a battery holder according to an embodiment of the present invention. Figure 6 This is a perspective view showing a state after the battery is assembled using the battery holder according to one embodiment of the present invention with a changed width.

[0033] like Figure 4 As shown, a battery using a battery holder according to an embodiment of the present invention includes a substrate holder 1 , a substrate 2 , a guide plate 3 , an insulating plate 4 , a battery housing 5 , a bottom cover 6 and a label 7 .

[0034] When the width of the upper surface of the battery housing 5 used is greater than or equal to the maximum width of the substrate support 1, during assembly, the fins of the substrate support 11 are retained and assembled directly. Figure 5 As shown, the fins 12 of the substrate holder 1 abut against the upper surface of the battery housing 5, and the maximum width of the substrate holder is less than or equal to the width of the upper surface of the battery housing 5, so that the substrate 2 is firmly supported on the battery housing 5 by the substrate holder 1 and the width of the substrate holder 1 does not exceed the width of the battery housing 5.

[0035] On the other hand, when the width of the upper surface of the battery case 5 used is smaller than the maximum width of the substrate holder 1 but greater than or equal to the minimum width of the substrate holder 1, the maximum width of the substrate holder 1 can be changed by cutting off a part of the fin 12 or cutting off the fin 12 as a whole, so that it is smaller than or equal to the width of the upper surface of the battery case 5 and then installed. Figure 6 Status shown.

[0036] By changing the maximum width of the substrate holder 1 as described above, the substrate holder 1 can be adapted to battery cases 5 of different types, thereby achieving the effect of reducing mold costs, unit prices of parts, and management costs.

[0037] As mentioned above, although one embodiment of the substrate holder of the present invention has been described, the present invention is not limited to the above-mentioned embodiment, and various changes can be made within the scope not departing from the gist of the present invention.

[0038] For example, in the above embodiment, the fin 12 is in the shape of a trapezoidal thin plate, but the shape of the fin 12 may be other shapes such as a triangle or a rectangle.

[0039] In the above embodiment, one set of fins is symmetrically formed on both sides of the holder body 11 , but one set of fins may be formed only on one side of the holder body 11 .

[0040] In addition, in the above embodiments, two different types of batteries are used as an example for description. However, the substrate support 1 of the present invention can be used for multiple different types of batteries, as long as the fins 12 are cut accordingly according to the battery types.

[0041] It is obvious to those skilled in the art that various omissions, changes and modifications can be made to the present invention without departing from the spirit or scope of the present invention. Therefore, it should be understood that the present invention includes changes and modifications within the scope of the attached claims and their equivalents. In particular, it should be understood that any combination of any part or all of any two or more of the above-mentioned embodiments and their modifications can be understood to be within the scope of the present invention.
