[0047] Based on this technical solution, the first connecting portion 2121 can be slid along the first direction X to adjust the distance between the first limiting portion 2122 and the second limiting portion 2132, so that the size of the first limiting groove 100 can be adjusted to accommodate batteries 8 of different models or different sizes, improving the versatility; the first connecting portion 2121 and the second connecting portion 2131 arranged at intervals can prevent the second connecting portion 2131 from interfering with the sliding of the first connecting portion 2121, and the operation is convenient and fast. In one embodiment, by providing an accommodating space 13 on the frame 1, a plurality of positioning mechanisms 2 can be arranged in the accommodating space 13, increasing the number of batteries 8 that the bracket can store. At the same time, the plurality of positioning mechanisms 2 can also be used to respectively accommodate multiple models or multiple sizes of batteries 8, so that the bracket can store multiple models or multiple sizes of batteries 8 at the same time, further improving the versatility.

[0048] In this embodiment, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs, and the first direction X, the second direction Y, and the third direction Z respectively correspond to the width direction, the length direction, and the height direction of the battery 8. In this embodiment, adjusting the distance between the first limiting portion 2122 and the second limiting portion 2132 can accommodate batteries 8 of different width sizes.

[0049] In this embodiment, two positioning mechanisms 2 are provided in the accommodating space 13, and the two positioning mechanisms 2 respectively accommodate two sizes of batteries 8.

In this way, sliding the first connecting portion 2121 can simultaneously adjust the sizes of multiple limiting grooves, and the operation is more convenient.

[0051] Preferably, the multiple first limiting portions 2122 are uniformly distributed on the first connecting portion 2121 along the first direction X; the multiple second limiting portions 2132 are uniformly distributed on the second connecting portion 2131 along the first direction X.

[0052] Refer to Figures 1 - 3 , the frame 12 provided by the embodiment of the present utility model is provided with a first through hole 121, a second through hole 122, a third through hole 123, and a fourth through hole 124 that communicate with the accommodating space 13. Providing through holes on the frame 12 can reduce the weight of the frame 1 and reduce the material cost of the frame 12.

[0053] Optionally, the number of the first through holes 121 may be one or more; the number of the second through holes 122 may be one or more; the number of the third through holes 123 may be one or more; the number of the fourth through holes 124 may be one or more.

[0056] In this embodiment, the second connecting portion 2131 is slidably connected to the first positioning member 211.

[0057] In some other embodiments, the second connecting portion 2131 may also be fixedly connected to the first positioning member 211.

The sliding of the second connecting portion 2131 can be guided and positioned by the second sliding groove 21132 to ensure that the second connecting portion 2131 can move smoothly and accurately on the second positioning member 221, with simple operation and convenient use; at the same time, the relative interference between the sliding of the first connecting portion 2121 and the sliding of the second connecting portion 2131 can be avoided by the spaced first sliding groove 21131 and the second sliding groove 21132.

[0059] Refer to Figure 2 , Figures 4 - 9The bracket provided in the embodiment of the utility model also includes a first fastener 3; the first positioning member 211 has a first connecting groove 21133 connected to the first slide groove 21131, the first connecting portion 2121 has a plurality of first connecting holes 21211 distributed along the first direction X, the first fastener 3 is passed through the first connecting groove 21133 along the second direction Y, and the first fastener 3 is connected to the hole wall of the first connecting hole 21211. In this way, after the battery 8 is placed in the first limiting groove 100, the first limiting member 212 can be slid so that the first limiting portion 2122 and the second limiting portion 2132 clamp and fix the battery 8, and then the first fastener 3 is passed through the first connecting groove 21133 and connected to the hole wall of any first connecting hole 21211, so that the first limiting member 212 can be locked on the first positioning member 211 and the sliding of the first limiting member 212 can be limited, so that the distance between the first limiting portion 2122 and the second limiting portion 2132 can be maintained and the first limiting portion 2122 and the second limiting portion 2132 can stably clamp the battery 8, thereby preventing the battery 8 from slipping off the positioning mechanism 2 and realizing the positioning of the battery 8 in the first direction X.

[0063] The aperture of the first connection hole 21211 is B mm, and the length of the first connection through slot 21133 in the first direction X is D mm, satisfying: B < D. In this way, by loosening the first fastener 3, the head of the first fastener 3 is disengaged from the side wall surface of the first positioning member 211 facing away from the first connection portion 2121. Since B < D, sliding the first limiting member 212 can drive the first fastener 3 to move along the first connection through slot 21133, so that the distance between the first limiting portion 2122 and the second limiting portion 2132 can be adjusted to accommodate batteries 8 of different widths. That is, loosening the first fastener 3 can achieve the unlocking between the first limiting member 212 and the first positioning member 211; by tightening the first fastener 3, the head of the first fastener 3 abuts against the side wall surface of the first positioning member 211 facing away from the first connecting member, and the first positioning member 211 can be clamped and fixed by the head of the first fastener 3 and the first connection portion 2121 to achieve the locking between the first positioning member 211 and the first limiting member 212, so as to maintain the distance between the first limiting portion 2122 and the second limiting portion 2132. Therefore, by tightening or loosening the first fastener 3, the locking or unlocking between the first positioning member 211 and the first limiting member 212 can be achieved, which is convenient to adjust and simple to operate.

[0064] Refer to Figures 1 - 3 , the first through hole 121 is located on the side of the first connection through slot 21133 facing away from the battery 8. The first direction X and the third direction Z intersect to form a first plane. Along the second direction Y, the positive projection of the groove wall of at least one first connection through slot 21133 on the first plane is within the range of the positive projection of the hole wall of at least one first through hole 121 on the first plane. In this way, the first through hole 121 can provide an operating space for the first fastener 3, so that the staff can more quickly achieve the locking or unlocking of the first positioning member 211 on the first limiting member 212 through the first fastener 3 through this operating space, improving the operation convenience.

[0065] Refer to Figure 1 , Figures 4 - 6 , Figure 8 and Figure 10 , the first positioning assembly 21 provided by the embodiment of the present invention further includes a first height positioning block 214. The first height positioning block 214 includes a main body portion 2141 and a buckle portion 2142. The buckle portion 2142 is connected to the main body portion 2141, and a buckle hole 21122 for buckling connection with the buckle portion 2142 is provided on the first positioning member 211. By using the buckle portion 2142 and the buckle hole 21122, the height of the battery 8 in the first limiting groove 100 can be adjusted by replacing different first height positioning blocks 214. That is, the provided bracket in this embodiment is not only applicable to the width change of the battery 8, but also applicable to the height change of the battery 8, further improving the versatility.
