Embodiment

[0024] Please refer to Figures 1-4 , the present invention is a lithium battery connection bracket, including a bracket for installing and connecting the lithium battery body 2; the bracket includes a plurality of connecting pieces 1 for fixing the lithium battery body 2, and the connecting piece 1 includes a positive end cap 12 sleeved outside the positive electrode of the lithium battery body 2, a negative end cap 11 sleeved outside the negative electrode of the lithium battery body 2, a knob 13 arranged on the sides of the negative end cap 11 and the positive end cap 12, a connecting groove 16 opened on the sides of the negative end cap 11 and the positive end cap 12, a connecting protrusion 17 extending on the sides of the negative end cap 11 and the positive end cap 12, a limiting block 14 integrally arranged at the corners of the outer sides of the negative end cap 11 and the positive end cap 12, and a protective pad 18 fittingly arranged on the side wall of the inner cavity 15 of the negative end cap 11 and the positive end cap 12.

[0025] Specifically, in the lithium battery connection bracket involved in the present application, the bracket is composed of a plurality of separated connecting pieces 1, so that the assembly quantity and assembly length of the bracket can be determined according to the actual connection and installation requirements of the lithium battery body 2, which is convenient for adjustment. Compared with the current fixed bracket structure, it has high practicability, simple overall structure, convenient combination and assembly, and low manufacturing cost. The connecting grooves 16 and connecting protrusions 17 arranged on the sides of the negative end cap 11 and the positive end cap 12 are used for the combined assembly between adjacent connecting pieces 1. After the connecting grooves 16 and connecting protrusions 17 of adjacent connecting pieces 1 are sequentially matched with each other, they are linearly arranged side by side to form a bracket for the combined connection of a plurality of lithium battery bodies 2.

[0026] Further, the protective pad 18 is sleeved on the peripheral side of the end of the lithium battery body 2, and the protective pad 18 is in contact and fit with the inner end of the thread of the knob 13; the limiting block 14 is in contact with the end of the lithium battery body 2, and the end corner of the limiting block 14 covers the outer opening edge of the cavity 15; equidistant continuous stripes are arranged on the peripheral side of the knob 13, and the inner end of the thread of the knob 13 is threadedly penetrated through the negative end cover 11 and the side surface of the positive end cover 12;

[0027] Specifically, the protective pad 18 is used for protecting the lithium battery body 2. When the negative end cover 11 and the positive end cover 12 are externally squeezed, the protective pad 18 deforms itself to achieve buffering of the squeezing effect and reduce the pressure borne by the end of the lithium battery body 2. The limiting block 14 integrally arranged at the outer corner of the side surfaces of the negative end cover 11 and the positive end cover 12 is used to block the movement of the lithium battery body 2. The setting of the knob 13 is also used to fix the position of the lithium battery body 2 relative to the negative end cover 11 and the positive end cover 12.

[0028] Further, a connecting groove 16 is arranged on the side surface of the negative end cover 11 and is matched with a connecting protrusion 17 extending from the side surface of the adjacent negative end cover 11. Similarly, a connecting groove 16 is arranged on the side surface of the positive end cover 12 and is also matched with a connecting protrusion 17 extending from the side surface of the adjacent positive end cover 12; the connecting groove 16 is arranged as a trapezoidal depression, and the connecting protrusion 17 is arranged as a trapezoidal protrusion. The connecting grooves 16 and the connecting protrusions 17 arranged on the side surfaces of the negative end cover 11 and the positive end cover 12 are arranged oppositely;

[0029] Specifically, the connecting grooves 16 and the connecting protrusions 17 arranged on the side surfaces of the negative end cover 11 and the positive end cover 12 are used for the combined assembly of adjacent connectors 1. After the connecting grooves 16 and the connecting protrusions 17 of adjacent connectors 1 are sequentially matched with each other, they are linearly arranged side by side to form a bracket for the combined connection of multiple lithium battery bodies 2.

[0030] Further, several connectors 1 in the bracket are linearly arranged side by side, and the distance between adjacent brackets is greater than the thickness of two knobs 13;

[0031] Specifically, the number of connectors 1 used in a single-row bracket and the number of brackets arranged side by side are determined by the actual connection requirements of the lithium battery body 2. However, it should be noted that the distance setting between the brackets arranged side by side is used to facilitate the rotation operation of the knob 13 and also for the rapid dissipation of the heat generated by the lithium battery body 2 during operation.

[0032] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification. These embodiments are selected and specifically described in this specification in order to better explain the principle and practical application of the present utility model, so that those skilled in the relevant art can well understand and utilize the present utility model. The present utility model is only limited by the claims and their full scope and equivalents.
