Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, in particular to a lithium battery pack with a fast wiring structure. Background Technique

[0002] With the wide application of lithium batteries in various fields such as portable electronic devices and electric vehicles, higher requirements are put forward for the assembly and maintenance of lithium battery packs. The wiring process of traditional lithium battery packs is cumbersome, time-consuming and prone to errors, which not only affects production efficiency, but also may lead to a decline in battery performance or even safety accidents due to improper wiring.

[0003] A Chinese patent with the publication number CN207651552U discloses a battery pack that is convenient for wiring connection. The patent includes a battery pack protective case, which is a hollow rectangular structure, and four groups of batteries are arranged in the battery pack protective case. The batteries are tightly connected, and the unconnected peripheries of the batteries are connected to the inner wall of the battery pack protective case through fixing parts. A cavity is provided in the battery pack protective case, and the cavity is fixedly connected between the battery and the battery pack protective case. A sleeve is arranged in the cavity, and the sleeve is fixedly connected to the bottom wall in the cavity. One end of the sleeve away from the cavity is provided with a telescopic rod, and one end of the telescopic rod is movably sleeved in the sleeve. By providing a cavity that can place the connecting wire, the connecting wire can be placed in the cavity when not in use, preventing damage from air and the environment. By providing a wire pressing wheel in the cavity that can adjust the wire length, it is convenient for users to use according to needs, and the limiting position of the connecting wire also facilitates connection.

[0004] Based on the above search and in combination with the prior art, it is found that:

[0005] In the existing device, by providing a cavity that can place the connecting wire and setting it in the cavity to prevent damage from air and the environment, but the connecting wires of lithium battery packs all have protective skins, which can effectively block the influence of the external environment. Instead, setting the cavity will occupy more space, which is not conducive to the flexible assembly of the battery pack. When wiring, a longer wire needs to be pulled out, and the wire cannot be reset and is exposed outside, which will cause danger and is not conducive to actual use. Content of the Utility Model

[0006] To solve the above technical problems, the present utility model proposes a lithium battery pack with a fast wiring structure. In this device, lithium batteries are placed on connection seats, and the lithium batteries are assembled by means of clamping, which can be flexibly assembled according to requirements into a battery pack of a suitable size, with relatively high practicality. The positive and negative poles of the battery pack are separated by a pair of protection plates, and wire winding rods on the pair of protection plates wind the wires. When wiring is required, the wires are pulled, and the wire winding rods rotate accordingly. The clockwork springs inside the wire winding rods are tightened. After wiring is completed, the wires are released, and the clockwork springs inside the wire winding rods reset, so that the wires can be restored to their original positions, avoiding the danger caused by the exposure of overly long wires being pulled.

The positive and negative electrodes of the pair of lithium batteries 9 are placed in opposite positions. A fixing plate 10 is sleeved on the multiple lithium batteries 9. Multiple through holes 11 are formed in the fixing plate 10. The size of the multiple through holes 11 corresponds to that of the lithium batteries 9. Multiple fourth clamping openings 12 are formed in the fixing plate 10. Fourth clamping openings 12 corresponding in position are formed in the bottom frame 1. A fourth clamping block 13 is clamped between the fourth clamping openings 12 between the fixing plate 10 and the bottom frame 1. The same-pole ends of the multiple lithium batteries 9 are connected with nickel sheets 14. In this device, the lithium batteries 9 are placed on the connection seats 2. The multiple connection seats 2 are horizontally connected by clamping the first clamping block 3 with the first clamping opening 4. The multiple connection seats 2 are vertically connected by clamping the second clamping block 6 with the second clamping opening 5. The adjacent connection seats 2 are connected by the third clamping block 8 to the third clamping openings 7 at the bottom of the adjacent connection seats 2, which can improve the stability between the connection seats 2. In the same way, the multiple connection seats 2 are clamped and fixed to the bottom frame 1.
