Automobile anti-pinch strip with high sensitivity and good sealing performance

Abstract

The invention relates to an automobile anti-pinch strip with high sensitivity and good sealing performance. The anti-pinch strip comprises an anti-pinch strip body with a compressible pipe, the leadsI, II, III and IV are respectively positioned in the conductors I, II, III and IV, and the conductors I, II, III and IV are circumferentially arranged in the compressible tube at equal intervals. A steel belt and a reinforcing rib for increasing the pull-out force are connected below the anti-pinch strip body, when the compressible pipe is subjected to the external extrusion, at least two conductors are in contact with each other, so that the short circuit is caused, the conduction of the internal circuits and the parallel connection of resistors are realized. The current change is caused by the change of the resistance of the loop resistors, the changed signals are transmitted to an ECU (electronic control unit) of a system, so that an anti-pinch function is realized, and an anti-pinch trigger angle of the anti-pinch strip reaches 360 degrees. The anti-pinch strip has the advantages of being high in anti-pinch sensitivity and good in sealing performance and has the very good market application prospect.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile anti-pinch strip with high sensitivity and good sealing performance. Background technique [0002] In recent years, with the rapid development of automobile technology, higher requirements have been put forward for the safety performance of the entire vehicle. The vehicles used by people are usually equipped with electric sliding doors to bring passengers more convenient and comfortable rides. experience. While the application of electric sliding doors brings convenience, a potential risk must also be taken into account, that is, the sliding door may pinch passengers during electric movement. In order to meet the technical requirements of preventing passengers from being pinched, the general electric sliding door will know the obstacle state by detecting the motor current parameters, or set up an anti-pinch bar, so as to know the obstacle state more directly, a...

AI Technical Summary

Problems solved by technology

This existing anti-pinch structure has a defect: when the driver drives the car immediately after closing the door, 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 may Cause injury or death; When closing the tailgate or side door of the car, when the hand, other parts or objects are accidentally in the closed state of the door, the hand or other parts will be pinched, which has a certain degree of safety hazard

[0005] 1) Sensitive anti-pinch cannot be realized;

[0006] 2) The sealing performance is poor. When a small object accidentally falls into the car, there will be a problem of blocking the water leakage system of the car door;

[0007] 3) The anti-pinch trigger angle cannot be guaranteed. When the car door is clamped by foreign objects at different angles, it cannot be sensitively touched, which brings unnecessary trouble to the user and sometimes even creates danger.

[0008] In view of the above-mentioned defects, the inventor has designed a car anti-pinch strip with high sensitivity and good sealing performance of the present invention, which has the advantages of high sensitivity and good sealing performance, and there is no report about the present invention
