High-voltage line protection device of new energy automobile

Abstract

The invention discloses a high-voltage line protection device of a new energy automobile. The high-voltage line protection device comprises a fixed strip, wherein a through groove is formed in the bottom of the fixed strip, two groups of positioning strips are welded with two sides of the bottom of the fixed strip, two groups of guide strips are symmetrically welded with two sides of an upper surface of each fixed strip, two groups of sliding blocks are arranged between the two groups of guide strips in a sliding way, each two groups of sliding blocks are arranged in the guide strips at equaldistance in an array way, capsules are arranged in a groove, cavities are formed in the capsules, the two groups of capsules are of semi-circular annular structures, sealing plates are fixedly arranged at two ends of the capsules, non-Newtonian fluid layers are poured into the cavities, thermal isolation layers are arranged on surfaces of inner circles of the capsules, two baffle plates are weldedwith a through hole, top rods are arranged in the two baffle plates in a penetrating way, outer circles of the top rods are arranged between the two groups of baffle plates, a spring is fixedly arranged, and spherical spring plugs are symmetrically screwed with two sides of the sliding blocks. By the high-voltage line protection device, protection of a high-voltage line during the collision process is achieved, and electric leakage is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of high voltage wires for automobiles, and in particular relates to a protective device for high voltage wires of new energy automobiles. Background technique [0002] With the advancement of science and technology and the continuous improvement of human living standards, the problems of energy shortage and environmental pollution have become increasingly prominent. As far as the automobile industry is concerned, new energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, and the adoption of new vehicle power devices), and the integration of advanced technologies in vehicle power control and drive to form It has become a major development trend to replace traditional power with new energy vehicles with advanced technical principles, new technologies and new structures. [0003] As an important part of electric new energy vehicles, high-vol...
