Embodiment Construction

[0019] Such as Figure 1-4 As shown, the high-strength battery box includes a lower casing 1 and an upper cover plate 2. The lower casing 1 is in the shape of a square barrel and is made of two layers of materials, including an inner stainless steel layer 11 and an outer carbon fiber layer. 12. The carbon fiber layer 12 is bonded to the outer surface of the stainless steel layer 11 by glue. The upper cover plate 2 is in the shape of a square plate. There is a square groove 21 on the inner side of the upper cover plate 2, and the upper end of the lower shell 1 can be snapped into In the groove 21, the side of the upper cover plate 2 is provided with a threaded hole 22, and the upper end of the lower housing 1 is correspondingly provided with a connecting hole 13, and the upper cover plate 2 is buckled on the top of the lower housing 1 and then inserted into the threaded hole 22 by a bolt. fixed.

[0020] The lower shell 1 has two layers, and the carbon fiber layer 12 can prote...

Abstract

The invention provides a high-strength battery case. The high-strength battery case comprises a lower casing and an upper cover plate, wherein the lower casing is in a square barrel shape and preparedfrom two layers of materials including an inner stainless steel layer and an outer carbon fiber layer, and the carbon fiber layer is stuck to the outer surface of the stainless steel layer through glue; the upper cover plate is in a square plate shape, a square groove is formed in the inner side of the upper cover plate, the upper end of the lower casing can be clamped into the groove, threaded holes are formed in the side edge of the upper cover plate, connecting holes are formed correspondingly in the upper end of the lower casing, and the upper cover plate is buckled to the upper part of the lower casing and then is fixed by inserting bolts into the threaded holes. The lower casing of the battery case is provided with double layers of materials, a stainless steel plate has better rigidity and strength, the carbon fiber material is lighter in weight, so that with adoption of the double layers of materials for the lower casing of the battery case, requirements for strength and rigidity are met, and the requirement for light weight is also met.

Description

technical field [0001] The invention belongs to the technical field of battery boxes and relates to a high-strength battery box. Background technique [0002] Battery Cases (Battery Cases, Enclosures), or battery cases, battery protection boxes, battery case shells, are used to accommodate and protect power batteries of electric and hybrid vehicles or ships, batteries of mobile phones or computers. In extreme cases, for example, when a car collides, the power battery may burn, explode, and produce toxic substances during the puncture impact, and the battery may be damaged, resulting in a safety accident. The main problems of battery boxes currently on the market are low mechanical strength, small box capacity, and heavy weight. If an aluminum box is used, although the weight is reduced, the strength is not very satisfactory. For this reason, a battery box with high strength, large capacity and light weight is required. The introduction of new materials, new processes, and ...
