Description

Lithium battery module with compact structure

Technical Field

The utility model relates to the technical field of battery modules, in particular to a lithium battery module with a compact structure.

Background

In the lithium battery module, can realize placing the battery as much as possible in limited space, reduce lithium battery weight, improve power density etc. and be the trade and pursue all the time, among the current lithium battery module, its inside assembly support volume is great, has occupied more space and weight, and it is great to lithium battery module promotion energy density and compact structure influence.

Thus, the prior art is deficient and needs improvement.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a lithium battery module with a compact structure.

The technical scheme of the utility model is as follows: the utility model provides a lithium battery module with a compact structure, which comprises: casing subassembly, a plurality of lithium cell, support device, be formed with accommodation space in the casing subassembly, a plurality of lithium cell and support device are all located in the accommodation space, support device includes a plurality of support units, and each support unit is including being used for fixing two supports at the battery cell both ends respectively, be formed with a plurality of holding chambeies on the support, the support is kept away from corresponding one side of battery cell is formed with the separation blade, the separation blade is used for spacingly the tip of lithium cell is formed with mounting groove on the partial separation blade, and is partial be formed with the installation projection on the separation blade, just mounting groove with installation projection and corresponding support unit phase-match.

Further, the lithium battery cell has a cylindrical shape,

further, the holding cavity is cylindrical and matched with the lithium battery unit.

Furthermore, the blocking pieces at the adjacent positions of the three accommodating cavities are triangular, and three angles of the triangle are respectively and correspondingly located at the accommodating cavities.

Further, the housing assembly includes an upper cover, a middle case, and a lower cover.

Detailed Description

The utility model is described in detail below with reference to the figures and the specific embodiments.

Referring to fig. 1 to fig. 4, in the present embodiment, the present invention provides a compact lithium battery module, including: casing subassembly, a plurality of lithium cell, support device, be formed with accommodation space in the casing subassembly, a plurality of lithium cell and support device are all located in the accommodation space, support device includes a plurality of support units, and each support unit is including being used for respectively fixing two supports 2 at the battery cell both ends, 2 are formed with a plurality of holding chambeies 21 on the support, support 2 keeps away from corresponding one side of battery cell is formed with separation blade 22, separation blade 22 is used for spacingly lithium cell's tip, part be formed with mounting groove 24 on the separation blade 22, part be formed with installation projection 23 on the separation blade, just mounting groove 24 with installation projection 23 and corresponding support unit phase-match. When this scheme uses, correspond two support 2 places a battery unit both ends that correspond respectively, and two are adjacent form on the support 2 mounting groove 24 month the assembly can be realized in the cooperation of installation projection 23 each other to realize the assembly of a plurality of battery unit end to end, adopt this kind of mode, support 2's small, light in weight can effectively reduce the volume and the weight of lithium cell module, make the structure compacter, energy density is higher, can satisfy the user demand.

Further, the lithium battery unit is cylindrical.

Furthermore, the blocking pieces 22 adjacent to the three accommodating cavities 21 are triangular, and three angles of the triangle are respectively and correspondingly located at the accommodating cavities 21.

Further, the housing assembly includes an upper cover 1, a middle case 2, and a lower cover 3.

Further, the material of the middle shell 2 is aluminum alloy.

To sum up, this scheme's beneficial effect lies in: the whole structure is compact, the volume and the weight occupied by the bracket are small, and the energy density and the weight of the battery module can be effectively improved

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
