A built-in protection type automotive expansion tank sensor

Abstract

The invention discloses a sensor for a built-in protection type automobile expansion tank, which includes a housing, a temperature sensor is screwed to the rear end of the left inner wall of the housing, and the left side of the temperature sensor extends out of the left side wall of the housing. The rear end of the right inner wall of the housing is equipped with a bimetal that is in contact with the front terminal of the temperature sensor. The right inner wall of the housing is located on the front side of the bimetal and has a first contact installed. A partition is installed in the middle of the cavity, and a second contact is installed in the middle of the left and right ends of the front side of the partition. The center of the front end of the left and right inner walls of the housing is connected to a rotating shaft through bearing rotation, and the outer wall of the rotating shaft is on the right. The sides are fitted with rectangular plates. The built-in protective car expansion water tank sensor not only has the function of prompting the driver that the temperature sensor is damaged and the engine temperature is too high, but also can detect and remind the water tank leakage to prevent the engine from overheating and damage.

Description

Technical field[0001]The present invention relates to the technical field of temperature sensor, in particular a built-in protective vehicle expansion water tank sensor.Background technique[0002]Automotive water tanks, also known as radiators, is the main machine parts in the automobile cooling system, and the function is to dissipate heat, and the cooling water absorbs heat in the water jacket, and the heat flows to the heat sink, and then returns to the water jacket, and reaches the temperature. It is an integral part of the automobile engine. The automotive water tank temperature sensor is a main component for detecting the temperature of the cooling water. The automotive water tank sensor is installed in the automotive instrument system. The temperature of the car engine cooling water is detected, so that the driver can intuitively understand the cooling water. The actual operating temperature and timely take the correct measures to ensure the normal play of the car function. Wh...

[0002] The car water tank, also known as the radiator, is the main part of the car cooling system. Its function is to dissipate heat. The cooling water absorbs heat in the water jacket. After flowing to the radiator, the heat dissipates, and then returns to the water jacket to circulate to achieve temperature regulation. , is an integral part of the car engine. The car water tank temperature sensor is the main component used to detect the temperature of the cooling water. The car water tank sensor is installed in the car instrument system. The sensor detects the temperature of the car engine cooling water, so that the driver can intuitively understand the cooling water temperature. The actual working temperature, and take corresponding correct measures in time to ensure the normal function of the car. In actual use, the temperature sensor will inevitably be aged and damaged if it is used for a long time. Once damaged, the car cooling system will be paralyzed, and it cannot Detecting and reminding water tank leakage may easily cause engine overheating damage, so a protective water tank sensor is now designed
