Please refer to FIG. 4 to FIG. 9. FIG. 4 is an exploded perspective view of the battery holder 10 of the battery device S of the present invention, and FIG. 4 is also an exploded view of the battery holder 10 of the present invention; FIG. 5 and FIG. FIG. 7 is a partial cross-sectional view of the lower frame body 11 of the battery holder; FIG. 8 is a partially enlarged plan view of the lower frame body 11 of the battery holder; FIG. 8 is a lower frame view of the lower frame body 11 of the battery holder A partial cross-sectional view of the body 11 is enlarged; FIG. 9 is a partial plan view of the lower frame 11. As shown, the wall of the lower frame 11 forming the respective perforations 11a is defined as a ring side wall 113, and each ring side wall 113 is along a longitudinal direction (i.e., the Z-axis direction shown in FIG. 5), from the side of the top surface 111. The direction of the bottom surface 112 (shown in FIG. 7) is recessed to form three recesses 11b, three The grooves 11b are not in communication with each other, and the three grooves 11b are spaced apart from each other, and the three grooves 11b correspond to the ring side walls 113 as three curved walls 1131. The three curved walls 1131 may have substantially the same outer shape, that is, the three grooves 11b may be substantially equally divided side walls 113. In this embodiment, the three recesses 11b are used to separate the ring sidewalls 113 into three curved walls 1131. However, the number of the recesses 11b is not limited thereto, and may be four according to requirements. More than one.

Referring to FIG. 7 and FIG. 8 together, the depth of each recess 11b defined by the concave surface of the top surface 111 is defined as a groove depth D1, and the depth of the through hole 11a in the longitudinal direction (the Z-axis direction as shown in the figure) is defined as a hole depth D2, the groove depth D1 is not equal to the hole depth D2, and each groove depth D1 is not less than one-half of the hole depth D2; preferably, the groove depth D1 may be two-thirds of the pierce depth D2 . Since the groove depth D1 is not equal to the piercing depth D2, the three arcuate walls 1131 separated by the ring side walls 113 are adjacent to the bottom surface 112 and are connected to each other, that is, as shown in FIG. Each of the curved walls 1131 includes a first portion 113A separated from each other and a second portion 113B connected to each other, and the three curved walls 1131 are not completely separated from each other, and thus, the mechanism for securing the respective curved walls 1131 strength. In other words, the groove depth D1 is not equal to the design of the piercing depth D2, and the design of the groove wall depth 1D is equal to the piercing depth D2, so that the curved walls 1131 have relatively good mechanical strength.

In addition, since the second portion 113B of the ring side wall 113 adjacent to the bottom surface 112 is not partitioned by the groove 11b, one end of the battery 20 can be effectively held. In other words, each of the ring side walls 113 includes a first portion 113A of three curved walls 1131 which can be moderately elastically deformed by an external force, and a second portion 113B which is not easily deformed by an external force, and transmits the two different properties. The portion of each ring sidewall 113 will effectively hold the battery 20. It is worth mentioning that the second portion 113B of each ring side wall 113 assumes an annular structure, and the diameter of the through hole 11a is equal to or slightly smaller than the outer diameter of the battery 20, and thus, the battery 20 can be effectively held.

As shown in FIG. 7 and FIG. 8 , the diameter of each of the through holes 11 a is gradually increased from the bottom surface 112 toward the top surface 111 , and the diameter of the through hole 11 a on the bottom surface 112 is substantially equal to the electric diameter. The outer diameter of the pool. In other words, the distance R1 of the curved wall 1131 adjacent to the inner side surface of the top surface 111 and the central axis of the through hole 11a is greater than the distance R2 of the curved inner wall 1131 adjacent to the inner side surface of the bottom surface 112 and the central axis of the through hole 11a.

As shown in FIGS. 5 and 6, each of the ring side walls 113 is formed with three convex portions 114, and the three convex portions 114 are formed by at least two curved walls 1131 at a position adjacent to the top surface 111 toward the central axis C of the through hole 11a. The protrusions are formed, and the respective convex portions 114 are correspondingly located at the corners of the curved wall 1131. Each of the protrusions 114 may be substantially rectangular, but not limited thereto, and the shape of the protrusions 114 may be changed according to requirements. As shown in FIG. 7, in practical applications, the distance R3 between the inner side surface 1141 of each convex portion 114 and the central axis may be substantially equal to or slightly less than one-half of the outer diameter of the battery.

Please refer to FIG. 9 , which is a top view of the lower frame 11 . In practical applications, the perforations 11a of the lower frame 11 may be in a circular shape, and the shortest distance between the three convex portions 114 and the center point O of the perforations 11a may be substantially the same. In addition, the three convex portions 114 may be correspondingly located at three equal positions of the through holes 11a which are formed in a circular shape, that is, the angle between any two convex portions 114 and the central axis of the through holes 11a is substantially the same. It is 120 degrees. As shown by the perforation 11a on the left side of FIG. 9, the three convex portions 114 may be correspondingly located on the two curved walls 1131, that is, one of the curved walls 1131 has two convex portions 114, and one of the curved walls 1131 It is included with only one convex portion 114, and the other curved wall 1131 does not have any convex portion 114. In different embodiments, as shown by the perforations 11a on the right side of FIG. 9, the three convex portions 114 may also be correspondingly located on the three curved walls 1131, and the three convex portions 114 are disposed adjacent to each other.

As shown in FIGS. 5 to 7, the lower frame body 11 further includes a plurality of escape grooves 12c, and each of the escape grooves 12c corresponds to a side of each of the convex portions 114 opposite to the central axis C of the through hole 11a. The geometric design of the outer shape, depth and width of the escaping groove 12c may be changed according to requirements, and only one of the exemplary aspects is shown in the figure, and is not limited thereto.

As described above, as shown in FIGS. 5 to 7, when one end of the single battery 20 (shown in FIG. 3) is moved in the longitudinal direction from one side of the top surface 111 toward the bottom surface 112, the corresponding insertion hole is inserted. In the case of 11a, the three convex portions 114 will be capped by the battery 20, and The portion of the corner of the curved wall 1131 to which the three convex portions 114 are connected will be elastically deformed to the corresponding escape groove 12c, and correspondingly generate an elastic restoring force, and the elastic restoring force will cause the three convex portions 114 to be clamped. Hold the battery 20.

In practical applications, each convex portion 114 is adjacent to one end of the top surface 111, and may have a guiding structure 1142. The guiding structure 1142 may be in the shape of a slope, and the guiding structure 1142 enables the battery 20 to enter more easily. Perforation 11a. Of course, the guiding structure 1142 may also be in the shape of a rounded corner, which is not limited herein.

As described above, as shown in FIGS. 3, 7, and 9, through the arrangement of the three convex portions 114, in the process of inserting the perforations 11a on the side of the top surface 111 of the lower frame 11 of the battery 20, three The convex portion 114 will guide the battery 20 such that the center line of the battery 20 substantially overlaps the central axis C of the through hole 11a, so that the battery 20 is correctly fixedly disposed on the lower frame 11, whereby the conventional technique can be avoided. Because the battery is not properly placed in the battery holder, the problem of subsequent assembly cannot be performed.

As shown in FIG. 7 and FIG. 8 , the convex portion 114 is adjacent to one end of the top surface 111 , and may be substantially flush with the top surface 111 , but is not limited thereto; however, each convex portion 114 is adjacent to one end of the top surface and The distance of the top surface 111 is smaller than the distance D3 between the end of each convex portion 114 adjacent to the bottom surface 112 and the bottom of the adjacent groove 11b. The convex portion 114 is disposed adjacent to the top surface 111, so that the corner portion of the curved wall 1131 can be elastically deformed when the convex portion 114 is abutted by the battery 20, so that the elastic restoring force is relatively easy to be generated, and thus It is made that the convex portion 114 relatively easily grips the battery 20 closely. Of course, in different embodiments, the convex portion 114 is adjacent to one end of the top surface 111, or may be spaced apart from the top surface 111 by a predetermined distance.

Specifically, as shown in FIG. 8, the length of each convex portion 114 in the longitudinal direction (ie, the depth direction of the through hole 11a, the Z-axis direction shown in FIG. 8) is smaller than the depth D1 of each groove, and thus, convex When the battery 20 is inserted into the through hole 11a, the portion 114 elastically deforms the arcuate wall 1131 easily. In other words, if the length of the convex portion 114 in the longitudinal direction is greater than or equal to the groove depth D1, the convex portion 114 will not easily elastically deform the curved wall 1131 when the battery 20 is inserted into the through hole 11a, or the curved wall 1131 The amount of elastic deformation will be relatively small, and as such, the clamping force of the projections 114 to hold the battery 20 will be relatively small.

It is to be noted that, as shown in FIG. 7 and FIG. 10, the lower frame body 11 may be provided with a plurality of limiting structures 115 on one side of the bottom surface 112, and the portions of the plurality of limiting structures 115 are correspondingly located in the plurality of perforations. In the case of 11a, the plurality of limiting structures 115 can limit the range of movement of the battery 20 located in the through hole 11a in the longitudinal direction (the Z-axis direction as shown in FIG. 7) so that the battery 20 disposed in the through hole 11a cannot pass. The through hole 11a is separated from the lower frame 11 by an opening formed by the bottom surface 112. In the embodiment of the present invention, the parts of the two limiting structures 115 are located in the same perforation 11a at the same time, but not limited thereto, and in different applications, correspondingly limited to a single perforation 11a. The number of bit structures 115 may also be one or more than three. In the embodiment in which the lower body 11 does not have the plurality of limiting structures 115, the battery holder 10 may be any member that is independent of the battery holder 10 (for example, the conductive plates B1, B2 of the battery device S of the present invention). The effect of limiting the range of movement of the battery 20 disposed in the perforation 11a in the longitudinal direction is achieved.

As shown in FIG. 1 to FIG. 3, the opposite sides of the upper frame body 12 are defined as a top surface 121 and a bottom surface 122, respectively. The upper frame body 12 has a plurality of through holes 12a extending therethrough, and the side wall forming the through hole 12a is defined as a ring side wall. 123. The ring sidewall 123 is recessed from the top surface 121 toward the bottom surface 122 to form three recesses 12b. The three recesses 12b are spaced apart from each other, and the three recesses 12b partition the ring sidewalls 123 into three arcs. The shape wall 1231 has a convex portion 124 protruding toward the central axis of the through hole 12a at a corner of each of the curved walls 1231. The upper frame 12 is formed with a relief groove 12c on a side of each convex portion 124 opposite to the through hole 12a. The upper body 12 is disposed on the bottom surface 122, and is further provided with a plurality of limiting structures 125. A portion of each of the limiting structures 125 is correspondingly located in the through hole 12a. The ring side wall 123 of the upper frame 12, the three recesses 12b, the three curved walls 1231, the three convex portions 124, the plurality of escape grooves 12c and the plurality of limiting structures 125 are connected to each other, and the lower frame The ring side wall 113 of the body 11 , the three recesses 11 b , the three curved walls 1131 , the three convex portions 114 , and the plurality of relief grooves 11 c have a plurality of limiting structures 115 All the same, no longer repeat them here. In other words, in practical applications, the lower frame body 11 and the upper frame body 12 can be manufactured by using the same mold, so that cost can be saved and installation can be facilitated. Of course, in different applications, the upper frame 12 may be manufactured by the same mold as the lower frame 11 , and the upper frame 12 only needs to be associated with the lower frame 11 to limit the battery 20 .

Please refer to FIG. 10, which is a cross-sectional view showing the battery holder 20 of the present invention holding the battery 20. When the battery 20 is inserted into the battery holder 10, each of the convex portions 114, 124 will clamp the battery 20 corresponding to the outer side wall of the top battery 20, and the two end faces of the battery 20 will correspond to the limit of the upper frame 12. The bit structure 125 and the limiting structure 115 of the lower frame 11.
