Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] Such as Figure 1-Figure 5 As shown, the present invention consists of a switch base 1, a guide rail 2, a blocking cover 3, a magnet 4, a collision cam 5, a roller 6, a connecting rod 7, a mandrel 8, a switch box 9, a shock reducing plug 10, a shock absorbing spring 11, a wiring Parts such as block 12, switch moving block 13, butterfly steel wire 14 and positioning sleeve 15 are formed. Wherein, the guide rail 2 is a square tube structure with open front and rear ends, and a blocking cover 3 is installed on the front end of the guide rail 2, and the front port of the guide rail 2 is sealed by the blocking cover 3. The rear end of the guide rail 2 is plugged with a magnet 4, which is fixedly connected with the guide rail 2, and the magnet 4 seals the rear port of the guide rail 2. The switch base 1 is a vertical plate structure and is located on one side below t...

Abstract

The invention discloses a safety switch for cutting electricity in collision of an electric automobile. A guide rail is arranged at the top of a switch base; a collision cam is arranged in the guide rail; a groove is arranged on the bottom surface of the collision cam; a trolley wheel is arranged in the groove and supported by the top of a mandril; the mandril is arranged in a switch box; a locating sleeve is fixedly sleeved in the middle of the mandril; the upper end of the locating sleeve is connected with the switch box through a butterfly steel wire; a switch motion block is fixed at the lower end of the locating sleeve; and two wiring blocks in contact and match with the motion block are installed on the switch box. When being collided, the electric automobile can act automatically and quickly to break a triggering switch and cut a circuit of a power battery pack which supplies power to the outside, electric leakage generated by collision is avoided, the problem of electric leakage caused by collision the electric automobile is solved, and the safety requirement of the electric automobile is satisfied. The invention has the advantages of usage of mechanical structure, simple structure, easy assembly and sensitive and reliable work.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a collision power-off safety switch on the electric vehicle. Background technique [0002] At present, the technology of new energy vehicles, especially electric vehicles, has gradually matured, and electric vehicles have entered the stage of test and demonstration operation. During the use of electric vehicles, collisions will inevitably occur, and after the collision, leakage will occur due to damage to the high-voltage circuit such as insulation damage, which will cause the body and chassis to be charged, which will easily cause secondary injuries to the occupants and vehicles, and even cause Start a fire. How to maximize the safety of people and vehicles in the car and meet the safety requirements of electric vehicles is a technical problem that electric vehicle companies need to solve urgently. Contents of the invention [0003] The technical proble...
