Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to an automotive water temperature gauge. Background Technology

[0002] During the use of a car, coolant is needed to cool the engine to ensure it operates at its normal operating temperature. For ease of management and control, the coolant temperature is usually displayed inside the vehicle using a water temperature gauge so that the driver can see it clearly.

[0003] Water thermometers are generally classified into mechanical and electronic types. Mechanical thermometers measure temperature using mechanical components (such as expansion tubes, temperature sensors, and pointers). Electronic thermometers, on the other hand, process the signals detected by the temperature sensor through a circuit board and display the data on a digital screen.

[0004] In the existing technology, the circuit board inside most electronic water temperature gauges is usually installed in the housing of the water temperature gauge by bonding or setting fasteners. Although this connection method can achieve a firm installation of the circuit board in the housing, it is inconvenient for staff to disassemble and repair the circuit board when it malfunctions.
