Automobile anti-pinch device sensitive to trigger, convenient to install and low in cost

Abstract

The invention relates to an automobile anti-pinch device sensitive to trigger, convenient to install and low in cost. The device comprises an anti-pinch strip body, a fixed support, a sealing cover, aconnecting wire, a wire interface and an anti-pinch controller; the anti-pinch strip body is an insulating rubber body whose interior is hollow, a first conductor, a second conductor, a third conductor and a fourth conductor are arranged on the inner surface of the insulating rubber body, and a wire is arranged in each conductor; the four conductors are arranged on the inner surface of the insulating rubber body at equal intervals in the circumferential direction, and a gap is reserved between every two conductors; an assembling part is arranged at the lower part of the insulating rubber body; and a resistor is arranged at the end of the anti-pinch strip body, and the two ends of the resistor are electrically connected with the wires. The device has the advantages that the structure is simple, the sensitivity is high, the cost is low, the technical problem that an anti-pinch module is low in sensitivity and cannot detect the state of an obstacle is solved, so that the sensitivity reduction and even failure caused by abrasion or oxidation of conductor parts are avoided, and the use safety is improved.

Description

technical field [0001] The invention relates to the technical field of automobile anti-clamping, in particular to an automobile anti-clamping device which is sensitive to trigger, easy to install and low in cost. Background technique [0002] At present, with the improvement of people's living standards, cars have entered thousands of households, and they play an increasingly important role in life, bringing a lot of convenience to people's travel, and at the same time better satisfying people's needs for comfort. Require. But when the car enters people's life, more and more relevant safety issues revolve around the car drivers and their families. For every person who rides in a car, unexpected safety protection problems arise, the most common of which is the problem that passengers, especially children, are inadvertently caught by the door caused by the rapid closing of the car door. In many cities There have been incidents in which car doors injure passengers in China. ...

AI Technical Summary

Problems solved by technology

[0004] The existing designs all have the following defects: during the starting process after the door is closed, or when the door is closed during driving, if the passenger is outside the door and the body or clothing is caught by the door, he will immediately fall down and be involved in the bottom of the car. and potentially fatal

But this device has changed the structural structure of the car door, and the cost is higher
