Embodiment Construction

[0027] Such as figure 1 , figure 2 As shown, a corrugated sandwich protective structure for an electric vehicle battery box includes a box body 1 and a box cover 2. The box body 1 is composed of a bottom plate 11 and four bottom wall panels 12 fixed around the bottom plate 11. The top non-enclosed casing for accommodating batteries; the box cover 2 includes a top plate 21 and four top panel wall panels 22 fixed around the top plate 21, and the box body 1 and the box cover 2 are formed by The fixing part arranged outside the upper end of the bottom wall panel 12 and the auxiliary fixing part arranged outside the lower end part of the top wall panel 22 are fixed together, and both the fixing part and the auxiliary fixing part are made of steel plates. The positioning hole is used to fasten the box body 1 and the box cover 2 into one body through the fixing piece and the auxiliary fixing piece through the bolt to form a closed space.

Abstract

The invention discloses a corrugated sandwich protective structure of a battery box of an electric vehicle. The protective structure comprises a box body and a box cover, wherein the box body is not closed at top, is composed of a baseplate and a baseplate wallboard fixed around the baseplate and is used for accommodating batteries; the box cover comprises a top plate and a top-plate wallboard fixed around the top plate, and the box cover and the box body are buckled so as to form a closed space. The protective structure is characterized in that the baseplate and the baseplate wallboard are respectively made of a corrugated sandwich protective plate. According to the invention, the box body and the box cover are made of the corrugated sandwich protective plates, so that the batteries can be prevented from being damaged; the corrugated sandwich protective structure has the advantages of high specific stiffness, high specific strength, high fatigue life, strong impact resistance and shock resistance, good impacting energy absorption property, light weight, and the like, thereby facilitating the promotion and application of electric vehicles and passenger cars.

Description

technical field [0001] The invention relates to a vehicle battery box, in particular to a corrugated sandwich protective structure suitable for the battery box of an electric vehicle. Background technique [0002] At present, with economic development, environmental pollution and other problems are becoming more and more serious, and there are more and more environmental protection measures and policies, especially the rapid development of electric vehicles and hybrid vehicles in recent years, making it possible for electric vehicles and hybrid vehicles to replace traditional vehicles , will greatly save energy and reduce vehicle exhaust pollution, which is in line with the environmental protection concept of green and low-carbon transportation industry. As the most important energy source of electric vehicles and hybrid vehicles, the battery voltage is increased, the number of battery cells and the total structural volume of the battery are increased, so as to ensure the po...
