Automobile temperature sensor and protection device

Abstract

The invention discloses an automobile temperature sensor and protection device, which comprises a sensor and a locking device, wherein the right end of the sensor is connected with a damping device, and a wrapping layer wraps the sensor and the damping device. A casing pipe sleeves the outer surface of the wrapping layer, the exterior of the casing pipe is provided with a circular pipe hoop, and the locking device is arranged in an inner cavity of the wrapping layer and is connected with the left end of the sensor. By arranging the damping device, the automobile temperature sensor and protection device can relieve the shock born by the sensor during the operation process of an automobile; by arranging the locking device, the sensor and an external protection device cannot break away from each other during the driving jolt of the automobile; and by arranging the circular pipe hoop, the protection device and the sensor can be connected tightly, thereby guaranteeing the accuracy of the sensor.

Description

technical field [0001] The invention relates to the technical field of automobile sensors, in particular to an automobile temperature sensor and a protection device. Background technique [0002] Temperature is a basic physical quantity, and all processes in nature are closely related to temperature. The temperature sensor is the earliest developed and most widely used type of sensor. The market share of temperature sensors greatly exceeds that of other sensors. Since the beginning of the seventeenth century, people have been using temperature for measurement. With the development of industrial technology, people began to use sensors in industrial equipment, such as temperature sensors for automobiles. In the prior art, temperature sensors have the following disadvantages: on the one hand, some sensors are exposed in various working environments and are very easy to damage. , so that the service life of the sensor is short and needs to be replaced. On the one hand, the te...

Problems solved by technology

With the development of industrial technology, people began to use sensors in industrial equipment, such as temperature sensors for automobiles. In the prior art, temperature sensors have the following disadvantages: on the one hand, some sensors are exposed in various working environments and are very easy to damage. , so that the service life of the sensor is short and needs to be replaced. On the one hand, the temperature sensor is prone to breakage due to vibration during the operation of the car. On the other hand, the current temperature sensor is not directly connected with the sensor protection. The sleeve phase contact makes the sensitivity of the temperature sensor not high, thus affecting the working reliability of the temperature sensor
