Automobile anti-pinch strip with high sensitivity

Abstract

The invention relates to an automobile anti-pinch strip with high sensitivity. The anti-pinch strip comprises an anti-pinch strip body with a compressible elastomer, a sealing cover, a wire and a wireopening. One end of the wire penetrates through the sealing cover to be connected with the anti-pinch strip body, and the other end is connected with the wire opening. The compressible elastomer internally comprises a first wire, a second wire, a first conductor, a second conductor and a resistor. The first wire and the second wire penetrate through the first conductor and the second conductor respectively, the first conductor and the second conductor are connected through the resistor, and the bottom end of the compressible elastomer is connected with the steel belt. When a foreign matter isclamped by an automobile door, the compressible elastomer on the anti-clamping strip is extruded, so that the first electric conductor and the second electric conductor are in contact with each other, the resistor is in short-circuit, a changed signal is transmitted to an ECU of a system, so that the anti-pinch function is achieved, and the anti-pinch triggering angle reaches 90 degrees. The anti-pinch strip is high in sensitivity and good in anti-pinch effect.

Description

technical field [0001] The invention relates to the technical field of automobile door anti-pinch, in particular to an automobile anti-pinch strip with high sensitivity. Background technique [0002] With the acceleration of the development and update of passenger cars, automakers no longer simply require auto suppliers to provide corresponding components according to drawings and standards, but require them to provide reliable, comfortable, and durable anti-pinch systems. It is required to have good sealing performance, anti-noise, anti-dust and vibration reduction after assembly, and sensitive anti-pinch effects, and requires small odor and elegant appearance. [0003] Most of the automobile anti-pinch strips in the prior art are fastened to the inner sheet metal of the automobile door through metal brackets. The number of parts is large, the weight is heavy, and the assembly process is many, so it is inconvenient to install. On the inner sheet metal of the door, these sc...

AI Technical Summary

Problems solved by technology

[0005] 1) poor airtightness of the car;

[0006] 2) The conductive part is separated from the anti-pinch part, the wires are exposed, which affects the appearance, and it is inconvenient to use and the sensitivity is not high

[0008] 3) Its anti-pinch trigger angle range is narrow, and it cannot achieve the effect of sensitive anti-pinch
