Embodiment Construction

[0016] The present invention will be further described below in conjunction with drawings and embodiments.

[0017] Such as Figure 1-Figure 5 As shown, the present invention consists of components such as switch base 1, guide rail 2, blocking cover 3, magnet 4, collision cam 5, roller 6, connecting rod 7, mandrel 8, switch box 9, shock absorbing plug 10 and shock absorbing spring 11. constitute. 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 the guide rail 2. The top of the switch base 1 is bent horizontally and connected to the side of the bottom...

Abstract

The invention discloses an impact cut-off switch driving mechanism of an electric vehicle. The top of a switch seat is provided with a guide rail; the front end of the guide rail is sealed by a plug and the back end of the guide rail is provided with a magnet; the guide rail is internally provided with an impact cam, the undersurface of the impact cam is provided with a groove, and the back end surface of the groove is a curved surface with a lifting characteristic; the groove is internally provided with an idler wheel, the center of the idler wheel is hinged with one end of a connecting rod,and the other end of the connecting rod is hinged with the guide rail; and the idler wheel is supported by the top of a central spindle which is arranged in a switch box in a penetrated mode, and theswitch box is connected with the guide rail fixedly. When electric vehicles are subjected to impact, the impact cut-off switch driving mechanism can act automatically and rapidly so as to disconnect a trigger switch, thus cutting off a circuit of a power battery pack for supplying power externally, thereby avoiding the electric leakage caused by the impact, solving the problem of the electric leakage due to the impact of the electric vehicles, and meeting the safety requirement of the electric vehicles. The impact cut-off switch driving mechanism is simple in mechanical structure and flexibleand reliable in operation, and easy to assemble.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a driving mechanism for a collision power-off 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...
