Detailed Implementation

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0027] See Figure 1-5 The combined lithium battery silicone sleeve shown includes individual silicone sleeves fitted onto the lithium battery cell 12. Multiple individual silicone sleeves are arranged in a matrix, and adjacent individual silicone sleeves are inserted into each other along a direction parallel to the axis of the individual silicone sleeves. The combined lithium battery silicone sleeve also includes a lower positioning frame disposed below the individual silicone sleeves and an upper positioning frame disposed above the individual silicone sleeves. The upper positioning frame is provided with multiple upper positioning rings 6 that correspond one-to-one with the upper end of the individual silicone sleeves, and the lower positioning frame is provided with multiple lower positioning rings 1 that correspond one-to-one with the lower end of the individual silicone sleeves. The upper positioning frame and the lower positioning frame are detachably connected by multiple bolts 10.

[0028] Through the implementation of the above technical solution, in use, the individual silicone sleeves are first placed on the lithium battery cells 12. Then, multiple lithium battery cells 12 with the silicone sleeves on are inserted one by one into the lower positioning ring 1 of the lower positioning frame. During the insertion of the lower positioning ring 1, adjacent silicone sleeves are also inserted and connected. After all the lithium battery cells 12 are assembled, the upper positioning frame is installed, so that the upper positioning ring 6 on the upper positioning frame is placed on the upper end of the individual silicone sleeves. Finally, the upper positioning frame and the lower positioning frame are locked together with multiple bolts 10. After the lithium battery module is assembled into a whole, the silicone sleeves are connected to each other to form an integrated heat dissipation structure, which effectively increases the heat dissipation effect. The silicone sleeves of adjacent cells are connected by contact heat conduction, which facilitates overall thermal management. At the same time, due to this design, the lithium battery cells 12 are better protected and their stability is increased. Furthermore, the number of individual silicone sleeves in this combined lithium battery silicone sleeve can be freely assembled according to the number of individual silicone sleeves in the lithium battery module. Only the upper and lower positioning frames of different specifications need to be replaced, which provides greater flexibility.

[0029] In this embodiment, to further provide a single silicone sleeve, the single silicone sleeve includes a cylindrical sleeve body 3, an upper annular stop 8 fixedly disposed on the upper end of the sleeve body 3, and a lower annular stop 2 sleeved on the lower end.

[0030] This design provides better protection for the lithium battery cell 12. The upper annular stop 8 and the lower annular stop 2 increase the contact area, thereby improving heat dissipation.

[0031] The single silicone sleeve in this utility model is made of thermally conductive silicone material with high thermal conductivity, electrical insulation, flexibility and temperature resistance.

[0032] In this embodiment, the upper outer side of the lower annular stop 2 is provided with an annular sleeve that fits onto the lower end of the sleeve body 3, and the lower outer side is provided with a lower annular right-angle groove 15, into which the lower positioning ring 1 is fitted. This arrangement allows the upper end of the lower annular stop 2 to fit onto the lower end of the sleeve body 3, while the lower positioning ring 1 fits into the lower annular right-angle groove 15, thus defining its position.

[0033] In this embodiment, an upper annular right-angle groove 18 is provided on the outer side of the upper annular stop 8, and the upper positioning ring 6 is sleeved in the upper annular right-angle groove 18. This arrangement allows the upper positioning ring 6 to be sleeved in the upper annular right-angle groove 18, thus defining its position.

[0034] In this embodiment, the sleeve 3 has a first insert 5 and a first slot 4 respectively on both sides in the first direction, and the sleeve 3 has a first insert 5 and a first slot 4 respectively on both sides in the second direction, with the first direction and the second direction being perpendicular to each other. For example, in one embodiment, the first insert 5 and the first slot 4 are both T-shaped, and the sleeve 3 is arranged in a clockwise direction along the circumference as a first insert 5, a first insert 5, a first slot 4, and a first slot 4. The first insert 5 and the first slot 4 adjacent on the left and right sides of the sleeve 3 are inserted into each other, and the first insert 5 and the first slot 4 adjacent on the top and bottom sides of the sleeve 3 are inserted into each other.

[0035] In this embodiment, the plurality of lower positioning rings 1 are connected by a first connecting rod 16, and the plurality of upper positioning rings 6 are connected by a second connecting rod 7. A plurality of lower mounting brackets 13 are fixedly connected between the plurality of first connecting rods 16, and a plurality of upper mounting brackets 9, corresponding one-to-one with the positions of the lower mounting brackets 13, are fixedly connected between the plurality of second connecting rods 7. Bolts 10 pass through the lower mounting brackets 13 and the upper mounting brackets 9. This design allows both the lower mounting brackets 13 and the upper mounting brackets 9 to have a hollow structure, facilitating better heat dissipation.

[0036] In this embodiment, mounting plates are provided in the middle of both the lower mounting bracket 13 and the upper mounting bracket 9. Each mounting plate has a through hole through which a bolt 10 passes. The upper end of the bolt 10 is locked by a nut 11. The bolt 10 passes through the lower through hole from bottom to top, then through the upper through hole, and is then locked by the nut 11.

[0037] In this embodiment, a support tube 14 is fixedly connected to the upper side of the mounting plate provided on the lower mounting bracket 13, and a countersunk hole 17 is provided on the lower side of the mounting plate provided on the lower mounting bracket 13.

[0038] With this configuration, the support tube 14 is used to support the upper and lower mounting plates, thereby increasing structural stability.
