Problems solved by technology

Automobile power battery packs are made of aluminum alloy materials, which have high temperature corrosion resistance and good heat transfer performance. With the development of energy saving, environmental protection and lightweight of automobiles, and the internal structure of battery pack shells is becoming more and more complex, the use of steel plates and aluminum alloys can no longer meet the requirements. Lightweight and internal complex structure requirements, so it is necessary to design a new battery pack case

Embodiment 1

[0018] like Figure 1-3 As shown in the figure, the SMC composite material molded battery pack case includes a lower case body 1. The lower case body 1 is a lower case body 1 formed by hot-melting glass fiber reinforced plastic, and the upper part of the lower case body 1 is open. The lower housing body 1 is provided with a first battery pack mounting portion 2 and a second battery pack mounting portion 3, and between the first battery pack mounting portion 2 and the second battery pack mounting portion 3 are sequentially arranged side-by-side The first intermediate battery pack mounting portion 4 , the second intermediate battery pack mounting portion 5 and the third intermediate battery pack mounting portion 6 , between the first battery pack mounting portion 2 and the first intermediate battery pack mounting portion 4 , the first intermediate battery Between the pack mounting portion 4 and the second intermediate battery pack mounting portion 5, between the second intermedi...

Embodiment 2

[0022] The molding process of the SMC composite molded battery case, including the upper mold and the lower mold (not marked in the figure). After injecting the hot-melt glass fiber reinforced plastic liquid, one-time molding obtains the SMC composite molded battery case. Under the premise of reducing weight, the shell strength is strengthened, it has good high temperature resistance and corrosion resistance, and the sealing performance is greatly improved.

Abstract

A SMC composite molded battery case and a molding process thereof are disclosed in the invention, A low shell body is integrally formed by fib reinforced plastic hot melt, Between that mount portionsof each battery pack, a horizontal corrugation is arrange, A limit groove is arranged on that inn wall of the first side of the lower housing body, A support boss is arrange on that inner wall of thesecond side of the low housing body, A first protrusion is provided in the first battery pack mounting portion, the upper surface of the first bump is provided with a horizontal groove, The second battery pack mounting part is provided with a second protrusion, a vertical protrusion is arranged on the inner wall of the lower case body, an anti-dumb notch is arranged at a corner of the upper edge of the lower case body, the left and right sides on the second side outer wall are respectively provided with concave parts, a convex part is arranged between the two concave parts, and the ground of the convex part is provided with an external groove. Made of glass fiber reinforced plastics (FRP) by hot melt forming, the shell strength is strengthened under the premise of lightening weight, and has good high temperature corrosion resistance, and greatly improves the sealing performance.

Description

technical field [0001] The invention relates to the technical field of electric vehicle accessories, in particular to an SMC composite material molded battery case and a molding process thereof. Background technique [0002] As the carrier of the battery module, the electric vehicle battery pack shell plays a key role in the safe work and protection of the battery module. Its appearance design is mainly carried out from the aspects of material, surface anti-corrosion, insulation treatment, product identification and so on. The traditional vehicle battery pack shell is cast with steel plate, aluminum alloy and other materials. Steel battery pack casing is the most primitive power battery pack casing material, which is generally welded by cast steel plates. The automotive power battery pack adopts aluminum alloy material, which has high temperature corrosion resistance and good heat transfer. With the development of automobile energy saving, environmental protection and ligh...
