Description

TECHNICAL FIELD

[0001] The utility model relates to a cylindrical battery support with pressure relief channel belongs to cylindrical battery support technical field. BACKGROUND

[0002] The role of the battery support in the cylindrical battery module is to install and position multiple single batteries. In the traditional cylindrical module, the bottom end face of the battery provided with the explosion-proof valve is closely attached to the bottom support, which causes the explosion-proof valve to be unable to normally open. The corresponding improved technical solution is to set a pressure relief port at the bottom. However, after the explosion-proof valve is opened due to thermal runaway of a certain battery, the discharged gas is still at the bottom of the battery, and cannot be discharged to the outside of the battery pack. The heat continuously spreads in the battery pack, which seriously affects the safety of other batteries, and even causes more serious safety hazards. Therefore, it is crucial to develop a cylindrical battery support with a pressure relief channel. SUMMARY

[0003] The utility model provides a cylindrical battery support with pressure relief channel in view of the deficiency existing in the prior art.

[0004] The utility model solves the technical problems in the above technical scheme as follows:

[0005] A cylindrical battery support with a pressure relief channel, comprising a cylindrical battery, a battery fixing disc adapted to the cylindrical battery is arranged below the cylindrical battery, a pressure relief hole is arranged on the battery fixing disc, a spliced support is arranged below the battery fixing disc, a pressure relief channel is arranged inside the spliced support, pressure relief channel splicing pieces are arranged on the left and right sides of the spliced support, and a plurality of fixing disc splicing holes and fixing disc splicing heads adapted to the fixing disc splicing holes are arranged on the front and back sides of the battery fixing disc.

[0006] Further, the pressure relief channel splicing piece comprises a convex connecting piece and a concave connecting groove.

[0007] Further, the number of the convex connecting piece and the concave connecting groove is one.

[0008] Further, the pressure relief hole penetrates through the corresponding position on the spliced support and communicates with the pressure relief channel.

[0009] Further, the number of the fixing disc splicing hole and the fixing disc splicing head is two.

[0010] Further, the fixing disc splicing hole and the adjacent fixing disc splicing head are connected to form a heat dissipation air duct.

[0011] Further, the lower end face of the fixing disc splicing hole and the fixing disc splicing head is on the same horizontal line as the lower end face of the battery fixing disc.

[0012] Compared with the prior art, the utility model has the advantages of:

[0013] Multiple battery bracket units are connected longitudinally and transversely through the cooperation of convex connectors and concave connecting grooves, as well as the cooperation of fixing plate assembly holes and fixing plate assembly heads. This facilitates quick and easy installation and forms a battery bracket group. At the bottom, except for the pressure relief channel, the connection of multiple brackets naturally forms a heat dissipation duct, which can serve as the bottom duct for radial heat dissipation of cylindrical batteries. In the event of thermal runaway in a cylindrical battery, the released gas enters the pressure relief channel through the pressure relief hole and is discharged outwards, reducing the risk of thermal spread throughout the battery module. This design is effective and improves the safety factor. The pressure relief channel and heat dissipation duct are arranged in parallel, allowing for use with a cooling fan to accelerate the discharge of released gas, reducing the concentration of released gas, lowering the risk of explosion, further improving the safety factor, and increasing work efficiency.
