Automobile braking warning sensor

Abstract

The invention relates to an automobile braking warning sensor, which comprises a shell, a line A and a line B, wherein the line A is connected with the line B; the line A and the line B are arranged in the shell; at least one line C is arranged between the line A and the line B; two ends of the line C are respectively connected with the line B and the line A; the line C is provided with at least one resistor; the lines A, B and C are solidified on the surface of a circuit board; a first warning point is formed at the connection part of the lines A and B; and a second warning point is formed at the connection part of the lines B and C. The invention adopts a two-stage circuit design principle, and the resistor is added, so that the warning sensor has reasonable product structure, good shielding effectiveness, stable and reliable signal transmission, can realize repeatedly warning so as to be convenient for a driver to master the time for replacing a brake sheet, and prevent the potential safety hazard of vehicles and improve the traveling safety factor.

Description

technical field [0001] The invention belongs to the technical field of vehicle accessories, in particular to a sensor, especially an automobile brake alarm sensor. Background technique [0002] The brake system is one of the important parts of the car, and its normality will be directly related to the safety of people's lives and property. Therefore, discovering and overhauling the brake system in time is one of the effective measures to reduce the accident rate and maintain the safety of people's lives and properties. At present, most of the existing brake alarm systems are single-point alarm systems, which have low alarm sensitivity, often false alarms, and easily cause traffic accidents. It is impossible to judge and predict whether the brakes will fail in advance. [0003] figure 1 It is a schematic diagram of the internal structure of an existing automobile brake alarm sensor, wherein the primary alarm point 9 is formed by connecting line B and line C. When the brake...

Problems solved by technology

Since the detection accuracy of the existing alarm sensor for the degree of wear of the brake pads and the use time after the alarm is not high, it is impossible to effectively measure the wear degree of the brake pads, so that the driver cannot accurately grasp the time to replace the brake pads, resulting in a complete failure of the brake pads. Malfunction, causing great hidden danger to driving safety
