[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] like Figures 1 to 6 As shown, a battery holder 100 according to an embodiment of the present utility model comprises a holder body 10 and a connection structure 20. A battery compartment 11 for installing a battery is formed inside the holder body 10, and the connection structure 20 comprises a first connection member and a second connection member which are arranged on the outer wall of the holder body 10 and can cooperate with each other, and two battery holders 100 are detachably connected through the first connection member and / or the second connection member.

[0029] In this embodiment, the battery holder 100 adopts a separate design, that is, each battery holder 100 can only install one battery, and when multiple batteries need to be installed, multiple battery holders 100 can be connected to form a holder group. Through such a setting, when installing different numbers of batteries, battery holders 100 with the same number of batteries can be selected for assembly, that is, the actual number of battery compartments 11 is the same as the actual number of batteries, and there is no vacant battery compartment 11, so the overall space utilization rate is higher and the use is more flexible.

[0030] Specifically, the first connecting member may be a boss 21 protruding from the outer wall surface of the bracket body 10, and the second connecting member may be a groove 22 recessed in the outer wall surface of the bracket body 10, and the boss 21 may be inserted into the groove 22 of another battery holder 100 to achieve positioning and connection of the two battery holders 100. After the boss 21 is inserted into the groove 22, the two battery holders 100 are closely attached to each other to further improve space utilization.

[0031] It should be noted that each battery holder 100 may be provided with only the first connecting member or only the second connecting member. For example, one of the battery holders 100 is provided with three grooves 22, and each of the other three battery holders 100 is provided with only one boss 21, then the battery holder provided with three grooves 22 can be connected with the other three battery holders provided with only one boss 21 to form the desired configuration of the battery holder group.

[0032] Of course, the bosses 21 and the grooves 22 may also be provided on a single battery holder 100 at the same time, and the number and positions of the bosses 21 and the grooves 22 included in each battery holder 100 are the same. In this case, only one mold needs to be opened during production, which makes production more convenient.

[0033] To prevent the two battery holders 100 from being separated, the width of the side of the boss 21 connected to the holder body 10 is smaller than the width of the side away from the holder body 10, that is, the boss 21 is larger outside and smaller inside in the radial direction of the battery compartment 11, and the bottom width of the corresponding groove 22 is larger than its opening width. Therefore, after the boss 21 is inserted into the groove 22, the two battery holders 100 cannot be directly released from the radial direction, and the stability is higher.

[0034] In a preferred embodiment, the boss 21 can be a T-shaped protrusion, and the groove 22 can be a T-shaped groove. Such a setting can limit and fix the boss 21 from both sides, thereby further improving the fixing effect, reducing shaking, and preventing the boss 21 from abnormally detaching from the groove 22.

[0035] like Figure 1 As shown, the boss 21 and the groove 22 extend along the axial direction of the bracket body 10 on the outer wall of part of the bracket body 10 respectively, and do not penetrate the side wall of the bracket body 10 as a whole. Therefore, the groove 22 is formed with an entrance 221 only on one side wall of the bracket body 10, and the other side is a closed design. Therefore, the boss 21 can only enter and exit from one side of the groove 22, avoiding the situation that the battery holder 100 may detach from the other side after installation, thereby improving stability.

[0036] It is conceivable that the length of a single boss 21 and groove 22 can be shortened, and multiple bosses 21 and grooves 22 with shorter lengths can be arranged along the same straight line on the outer wall of the bracket body 10, and the spacing between two adjacent connection structures 20 can be the same or different.

[0037] In actual use, the battery arrangement usually adopts a two-dimensional planar distribution structure. To match this distribution mode, each battery holder 100 needs to be connected to multiple other battery holders 100, so multiple bosses 21 and multiple grooves 22 need to be provided on the holder body 10. It is conceivable that the bosses 21 and grooves 22 can be arranged irregularly on the holder body 10, and the number of the bosses 21 and the grooves 22 can be the same or different to form a battery holder group of a desired configuration.

[0038] The arrangement of two adjacent battery holders 100 is horizontal, vertical or oblique. For this purpose, a horizontal group connection structure 31 and a vertical group connection structure 32 are provided on the outer wall of the holder body 10. The two structures respectively include a group of relatively arranged bosses 21 and grooves 22, and the bosses 21 and grooves 22 in the two structure groups are perpendicular to each other. Four other battery holders 100 can be installed on the periphery of each battery holder 100, and when the holder group is formed, the battery holders 100 are distributed in a "well" shape.

[0039] In order to further improve the space utilization, multiple battery holders 100 can be arranged in a honeycomb shape, and each battery holder 100 is externally connected to 6 other battery holders 100. To this end, two additional groups of oblique group connection structures 33 are required, each group of oblique group connection structures 33 includes a group of protrusions 21 and grooves 22 relatively arranged on the bracket body 10, and the two groups of oblique group connection structures 33 are distributed on both sides of the longitudinal group connection structure 32.

[0040] In a preferred embodiment, the angle between the boss 21 in the longitudinal group connection structure 32 at the top of the main support 10 and the boss 21 in the oblique group connection structures 33 on both sides is 30 degrees. Therefore, the angles between the two groups of oblique group connection structures 33 and the transverse group connection structure 31 are both 60 degrees, and 6 other battery supports 100 can be connected to the periphery of a single battery support 100, and adjacent battery supports 100 are closely attached to each other to form a honeycomb structure.

[0041] By setting the above four groups of structures, a single battery holder 100 has up to eight connection points, so that a single battery holder 100 can be connected to four or six other battery holders 100 at the same time, which is more flexible. The above four groups of structures have covered all connection methods, so the total number and position of the bosses 21 and the grooves 22 are determined, and no other bosses 21 or grooves 22 are required to reduce production costs and difficulty, and prevent interference with other battery holders 100 during connection.

[0042] Under the above setting quantity, position and angle of the bosses 21 and the grooves 22, multiple battery holders 100 are connected and fixed in a regular arrangement form ("well" shape and honeycomb shape). It should be understood that the actual setting quantity and angle between the bosses 21 and the grooves 22 can be adjusted to change the arrangement of the battery holders 100 in the holder group.

[0043] In one embodiment, the bracket body 10 is a cylindrical structure, and the boss 21 is connected to other adjacent bosses 21 / grooves 22 by an arc surface. Of course, in other embodiments, the bracket body 10 can also be a regular polygonal structure, that is, the boss 21 is connected to other adjacent bosses 21 / grooves 22 by a plane.

[0044] At the same time, the boss 21 in the longitudinal group connection structure 32 is located between the two bosses 21 of the two groups of oblique group connection structures 33, that is, the three bosses 21 are located on the same side, and the arrangement form is relatively regular. Of course, the positions of the bosses 21 and the grooves 22 in any structure group can also be swapped, and this embodiment is not limited.

[0045] The present embodiment also provides a battery holder 100, comprising a holder body 10 and a connection structure 20. The holder body 10 is an integral structure, and a battery compartment 11 for installing some batteries is formed therein. The connection structure 20 comprises at least one first connection portion and at least one second connection portion arranged on the outer wall of the holder body 10, and the first connection portion or the second connection portion is used to cooperate with the second connection portion or the first connection portion of another battery holder 100 to detachably connect the two battery holders 100 together. The first connection portion is a boss 21 protruding from the outer wall of the holder body 10, and the second connection portion is a groove 22 recessed in the holder body 10 and capable of cooperating with the boss 21. The connection structure 20 includes a transverse group connection structure 31, a longitudinal group connection structure 32, and two groups of oblique group connection structures 33 located on both sides of the longitudinal group connection structure 32, each of which includes a group of bosses 21 and grooves 22 arranged opposite to each other, and the diameter of the transverse group connection structure 31 is perpendicular to the diameter of the longitudinal group connection structure 32, and the bosses 21 and grooves 22 in the longitudinal group connection structure 32 are arranged longitudinally on the bracket body 10. One group of oblique group connection structures 33 includes a boss 21 or groove 22 located on the left side of the longitudinally arranged boss 21, and a groove 22 or boss 21 located on the right side of the longitudinally arranged groove 22, and the other group of oblique group connection structures 33 includes a boss 21 or groove 22 located on the right side of the longitudinally arranged boss 21, and a groove 22 or boss 21 located on the left side of the longitudinally arranged groove 22. Therefore, the battery bracket 100 has multiple groups of connection mechanisms, and multiple battery brackets 100 can have a variety of different fixed positions, which is highly flexible.

[0046] In a preferred embodiment, the angle between the boss 21 or the groove 22 in the longitudinal group connection mechanism 32 and the boss 21 or the groove 22 in the two groups of oblique group connection structures 33 on the same side is 30 degrees. Therefore, when assembling multiple battery racks 100, the angle between adjacent battery racks 100 is fixed and arranged in a tic-tac-toe or honeycomb shape, and the arrangement is regular.

[0047] like Figure 7-8 As shown, this embodiment also provides a battery pack 200, which is formed by connecting a plurality of the above-mentioned battery assemblies 100, and the adjacent batteries 100 are connected and fixed by a first connector and a second connector, wherein at least part of the battery compartment 11 contains batteries. The battery pack 200 can have a variety of connection modes, such as the single string structure shown in the figure, the three string structure shown in the figure, the multi-string two parallel structure shown in the figure, and the multi-string three parallel (honeycomb) structure shown in the figure, or can be set to other special-shaped structures according to actual conditions, and the specific connection mode can be selected according to the actual number of batteries, container size and dimensions, etc., with high flexibility.
