Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a lithium battery pack box. Background Art

[0002] At present, lithium batteries are gradually gaining favor in the market due to their relatively long lifespan. However, due to the low energy density of a single lithium battery, the market generally uses multiple single lithium batteries connected in series to form a lithium battery pack to meet the energy needs. In existing technologies, multiple groups of lithium batteries will generate a lot of heat when working at the same time. The poor heat dissipation of the box used for lithium battery assembly can directly lead to the lithium battery being exposed to high temperature for a long time, which may eventually shorten the life of the lithium battery and even cause safety hazards.

[0003] The prior art discloses a lithium battery assembly box with application number CN202022553401.3, which sets forth a heat dissipation component, and connects the heat dissipation rods and the support plate to introduce heat generated by a lithium battery placed between the heat dissipation rods and with the bottom surface fixed to the upper end of the support plate into the heat dissipation box at the lower end of the assembly box through the heat dissipation rods, thereby realizing heat transfer inside the assembly box and avoiding excessive heat inside the assembly box and shortening the life of the lithium battery. By setting up the heat dissipation box, a groove is provided at the upper end of the heat-conducting bottom plate at a position corresponding to the heat dissipation rod, and heat dissipation plates are provided on both sides of the groove. When the heat dissipation rod transfers the heat inside the assembly box to the heat dissipation box, the heat passes between two adjacent heat dissipation plates and is then exported to the outside of the heat dissipation box through the heat dissipation holes by the airflow of the blast pipe.

[0004] However, there are still certain defects in the prior art. For example, the technical solution described in the above patent lacks an auxiliary installation mechanism for the battery during use, which makes the installation more troublesome and the connection method more complicated. At the same time, the installation of the battery requires manual assistance, and lithium batteries have a certain degree of risk of spontaneous combustion, and the installation workers have a certain degree of risk of injury.

[0028] like Figure 2 As shown, a power connection plate 11 is fixedly connected to the front inner side wall of the installation box 1, a power contact plate 12 is fixedly connected to the outer side of the power connection plate 11, a telescopic slot 13 is opened on the top of the rear end of the installation box 1, and movable support rods 14 are fixedly connected to both sides of the rear end of the installation box 1.

[0029] By installing the power connection plate 11 and the power contact plate 12 at the front end of the box body 1, the battery can be put into use. The control support plate 2 is supported by the telescopic groove 13, so that the control support plate 2 can assist in supporting the battery supporting plate 5 and is assisted in movement by the movable support rod 14.

[0030] like Figure 3 As shown, the outer side of the control support plate 2 is slidably connected to the inner side of the telescopic groove 13, and the outer side of the control support plate 2 is toothed with a transmission gear 21, and the end of the transmission gear 21 away from the control support plate 2 is toothed with a driven gear 22, and the bottom end of the driven gear 22 is fixedly connected to a gear fixing support rod 23, and the outer side of the driven gear 22 is toothed with a supporting connecting rod 24.

[0031] The inclined part of the front end of the control support plate 2 is used to assist in supporting the battery supporting plate 5. After the battery supporting plate 5 is used to support the battery, the battery supporting plate 5 is moved toward the bottom end, and the control support plate 2 is moved toward the rear end, driving the transmission gear 21 to rotate, and the transmission gear 21 drives the driven gear 22, so that the driven gear 22 drives the support connecting rod 24 to move, so that the support connecting rod 24 can be driven toward the rear end, so that the battery supporting plate 5 can move toward the bottom end.

[0032] like Figure 4 As shown, a feed bearing plate 31 is fixedly connected to the outer side of the feed bracket 3 , and a feed fixing plate 32 is fixedly connected to the rear end of the feed bracket 3 .

[0033] The material loading plate 31 and the material loading fixing plate 32 on the outside of the material loading bracket 3 are used to support the material receiving box 4 , so as to facilitate the introduction of the battery loading plate 5 on the inside of the material receiving box 4 into the installation box 1 .
