Description

Technical Field

[0001] The utility model relates to the technical field of automobile water temperature sensors, in particular to a novel automobile water temperature sensor. Background Art

[0002] The use of sensor technology in the automotive field is also relatively common. The automotive water temperature sensor is an important component of the engine control system. The structure of the automotive water temperature sensor includes a metal shell, the outside of the metal shell is provided with a thread that cooperates with the automobile engine, the inside of the metal shell is provided with a thermistor, and a connector connecting the thermistor and external equipment.

[0003] The utility model patent application document with announcement number "CN208026392U" discloses an automobile water temperature sensor, which is mainly composed of a metal shell, a connector, a thermistor, a hexagonal base, an adsorption plate and a negative ion film. The water temperature sensor of this technical solution can detect water temperature more accurately.

[0004] The automobile water temperature sensor disclosed in the above document has the following defects: the water temperature sensor is removed from the automobile by using a tool to rotate the hexagonal base counterclockwise to rotate the thread out of the threaded hole of the automobile. If there are no external tools, the water temperature sensor cannot be removed from the automobile, and replacement and maintenance cannot be completed, so the practicality is poor.

[0005] It can be seen from this that the existing automobile water temperature sensor does not have a good disassembly structure, and it is necessary to improve the existing deficiencies and provide a new automobile water temperature sensor. Utility Model Content

[0009] Furthermore, the disassembly assembly includes a connecting plate, a chamber is provided inside the connecting plate, a slider is slidably connected inside the chamber, the slider is fixed in two and symmetrically arranged, a spring is installed between the two sliders, a clamping block is installed at the end of the slider away from the spring, one end of the clamping block passes through the connecting plate and extends outward, an installation groove is provided on the outer surface of the base, a connecting shaft is installed inside the installation groove, the outer surface of the connecting shaft is rotatably connected to the connecting plate, a connecting block is provided on the upper surface of the base, a mounting hole is provided in the middle of the connecting block, and a clamping block is installed in the mounting hole.

[0013] Furthermore, the outer surface of the shell and the outer surface of the disassembly assembly are coated with a high temperature resistant coating.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model squeezes two blocks so that the two sliders slide toward one end closer to each other in the chamber while the spring gradually contracts. When the blocks are separated from the mounting hole and are flush with the outer surface of the connecting plate, the connecting plate can be pulled outward so that the connecting plate moves axially downward with the connecting shaft as the center. When the connecting plate is separated from the mounting groove, the external thread of the shell is separated from the threaded hole by pressing the connecting plate with a finger and then turning it counterclockwise. The water temperature sensor can be removed from the car, which is convenient for replacement and maintenance, and has a better use effect.
