[0024] For the embodiment of the battery holder 1 of the present invention, please refer to Figure 1 and Figure 2 As shown, it includes a first supporting seat 11, a second supporting seat 12, a plurality of latching holes 13, and a plurality of latching portions 14. The first supporting seat 11 has a plurality of first accommodating holes 111 arranged in a staggered manner. The second supporting seat 12 is connected to the first supporting seat 11. The second supporting seat 12 has a plurality of second accommodating holes 121 arranged in a staggered manner. The positions of the plurality of second accommodating holes 121 correspond to the positions of the plurality of first accommodating holes 111, and the corresponding second accommodating holes 121 and first accommodating holes 111 are used to accommodate a battery 2. The plurality of latching holes 13 are provided on the first supporting seat 11. The plurality of latching portions 14 are provided on the second supporting seat 12.

[0025] Therefore, the present invention provides the multiple card holes 13 on the first supporting seat 11 of the battery holder 1, and provides the multiple snap parts 14 on the second supporting seat 12 of the battery holder 1, so that the battery holder 1 and another battery holder 1 can be combined through the multiple card holes 13 and the multiple snap parts 14, for example, assembled and combined in a buckled manner, thereby improving the convenience and stability of the overall structure.

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, the corresponding first receiving hole 111 and the second receiving hole 121 are coaxially arranged, and the battery 2 is inserted into the corresponding first receiving hole 111 and the second receiving hole 121, so that the corresponding first receiving hole 111 and the second receiving hole 121 respectively receive and secure the two ends of the battery 2. For example, the battery 2 can be a cylindrical lithium-ion battery, but is not limited to this.

[0027] To explain the detailed arrangement and structure of the plurality of latch holes 13, please refer to Figures 1 to 3 As shown, in this embodiment, the first supporting seat 11 has a first front side 112 and a first rear side 113 opposite to each other. The first front side 112 of the first supporting seat 11 is farther away from the second supporting seat 12 than the first rear side 113. The plurality of latching holes 13 are disposed on the first front side 112 of the first supporting seat 11 and are arranged in a staggered manner. Figure 3As shown, in this embodiment, each of the latching portions 13 has a body 131 and a through hole 132. The body 131 is formed into a ring shape by protruding forward from the first front side 112 of the first supporting base 11, and the through hole 132 is formed on the sidewall of the body 131. For example, the shape of the body 131 may include a circular ring, a square ring, a triangular ring, or a polygonal ring, but is not limited thereto.

[0028] To explain the detailed arrangement and structure of the plurality of buckle portions 14, please refer to Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the second supporting base 12 has a second front side 122 and a second rear side 123 opposite to each other. The second front side 122 of the second supporting base 12 is closer to the first supporting base 11 than the second rear side 123. The second front side 122 of the second supporting base 12 is connected to the first rear side 113 of the first supporting base 11, and the plurality of latching portions 14 are disposed on the second rear side 123 of the second supporting base 12 and are arranged in a staggered manner.

[0029] like Figure 4 As shown, in this embodiment, each of the latching portions 14 comprises a butting protrusion 141, a positioning protrusion 142, and a latching spring arm 143. The butting protrusion 141 and the positioning protrusion 142 each protrude rearward from the second rear side 123 of the second support base 12 and form a U-shape. The latching spring arm 143 extends rearward from the second rear side 123 of the second support base 12 to form a strip, and the rear end of the latching spring arm 143 further forms a barbed latching end 1431. In this embodiment, the positioning protrusion 142 connects the butting protrusion 141 and the latching spring arm 143.

[0030] To illustrate the specific assembly method between the battery brackets 1, please refer to Figure 5 and Figure 6As shown, when the battery holder 1 is assembled with another battery holder 1, the multiple latching portions 14 of the second supporting seat 12 of the battery holder 1 will be aligned with the multiple latching holes 13 of the first supporting seat 11 of the other battery holder 1. The positioning protrusions 142 and latching spring arms 143 of the multiple latching portions 14 will be aligned and inserted into the bodies 131 of the multiple latching holes 13, respectively. The latching ends 1431 of the multiple latching spring arms 143 will be guided along the sidewalls of the bodies 131 of the multiple latching holes 13, causing the multiple latching spring arms 143 to retract and deform inward. When the abutting protrusions 141 of the multiple snap-fit ​​parts 14 abut against the main bodies 131 of the multiple snap-fitting parts 13, the snap-fitting ends 1431 of the multiple snap-fitting elastic arms 143 will respectively spring outward, so that the snap-fitting ends 1431 of the multiple snap-fitting elastic arms 143 are respectively tightly snapped into the through holes 132 of the multiple snap-fitting parts 13, thereby achieving the function of fixing the battery holder 1 to another battery holder 1.

[0031] In order to enhance the assembly strength between the battery brackets 1, as Figure 3 and Figure 4 As shown, in this embodiment, two adjacent latching holes 13 are disposed opposite to each other, and two adjacent buckle portions 14 are disposed opposite to each other corresponding to the plurality of latching holes 13 .

[0032] For example, the through holes 132 of two adjacent latching portions 13 are respectively opened in opposite directions. For example, the through hole 132 of one latching portion 13 may be disposed upward on the side wall of its body 131, while the through hole 132 of the other latching portion 13 may be disposed downward on the side wall of its body 131. The two adjacent latching portions 14 are respectively disposed in opposite directions. For example, the latching spring arm 143 of one latching portion 14 may be located above its abutting protrusion 141 and positioning protrusion 142, and the latching end 1431 of the latching spring arm 143 may be protruding upward to form a barb shape. The latching spring arm 143 of the other latching portion 14 may be located below its abutting protrusion 141 and positioning protrusion 142, and the latching end 1431 of the latching spring arm 143 may be protruding downward to form a barb shape. In this way, the snap arm 143 with the snap end 1431 protruding upward will be snapped into the snap hole portion 13 with the through hole 132 facing upward, and the snap arm 143 with the snap end 1431 protruding downward will be snapped into the snap hole portion 13 with the through hole 132 facing downward, so as to strengthen the assembly strength between the battery holders 1 by snapping in opposite directions.

[0033] Based on the above embodiments of the present invention, a battery module can be further provided, wherein the battery module includes the battery holder 1 in the above embodiments. The relevant structural configuration of the battery holder 1 is as described above, so it will not be repeated here.

[0034] In summary, the present invention improves the battery bracket structure through the above-mentioned structure, by arranging the multiple card holes on the first supporting seat of the battery bracket and arranging the multiple buckle parts on the second supporting seat of the battery bracket, so that the battery bracket and another battery bracket can be combined through the multiple card holes and the multiple buckle parts, thereby achieving the effect of improving the stability of the overall structure.
