Description

Technical Field

[0001] The utility model specifically relates to the technical field of sensors, in particular to a car shell temperature sensor. Background Art

[0002] The car shell temperature sensor is also called the ambient temperature sensor. It is a component of the automatic air conditioning control system. The external ambient temperature sensor is generally installed on the front bumper mounting bracket and is also a thermistor. Its function is to detect the temperature outside the car. The control system will determine the control method based on the difference between the external temperature and the internal temperature. For example, when the ambient temperature is low, the system will disconnect the compressor clutch power supply and stop the air conditioning refrigeration system.

[0003] The existing external temperature sensor is a temperature probe that is directly fixed to the front bumper of the car. However, after long-term bumps and driving of the vehicle, it will become loose or fall off, resulting in the sensor's inaccurate external temperature sensing and large errors; it is impossible to transmit the real temperature data to the central control system. Utility Model Content
