Description

Technical Field

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

[0002] The vehicle sensor is the input device of the vehicle computer system. It converts various operating information of the vehicle during operation, such as vehicle speed, temperature of various media, engine operating conditions, etc., into electrical signals and transmits them to the computer so that the engine is in the best working state. There are many vehicle sensors. When judging the failure of the sensor, we should not only consider the sensor itself, but also the entire circuit where the failure occurs. Therefore, when finding the fault, in addition to checking the sensor, we should also check the wiring harness, connectors, and related circuits between the sensor and the electronic control unit.

[0003] Car tires are an important component of a car and play a vital role in ensuring the safe driving of the car. The function of the tire pressure monitoring system is to automatically monitor the tire pressure in real time during the driving of the car, and to alarm for tire leakage and low pressure to ensure driving safety.

[0004] In the prior art, the tire pressure sensor is not convenient to disassemble after installation, and the air nozzle needs to be fixed and the sensor needs to be twisted for disassembly, which has a certain impact on the replacement and maintenance of the sensor.

[0005] Since the tire pressure sensor uses a button battery, it has a limited amount of power. After a period of time, the power runs out and needs to be replaced. The sensor needs to be disassembled as a whole and the battery needs to be replaced. The replacement process is too cumbersome. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The automobile sensor realizes rapid installation and removal of the sensor by arranging structures such as a shell, a fixed sleeve, and a pressure relief pad. The slider is placed in the slide groove and the shell is pressed downward, the pressure relief pad is contracted, the connecting tube contacts the air nozzle, the shell is rotated, and the thread groove rotates along with the slide groove. When the slider is rotated to the bottom of the slot, the spiral coil is engaged with the outer spiral groove, so that the connecting tube is connected to the air nozzle, and the force pressing the shell is released. The pressure relief pad releases the force restriction, drives the shell to pop up, and the slider is stuck in the slot to fix the position of the shell. Conversely, the shell is pressed and rotated in the opposite direction to make the spiral coil break away from the restriction of the outer spiral groove, pull the shell out, and make the shell away from the fixed sleeve, so that the sensor can be quickly installed and removed.

[0014] 2. The automobile sensor realizes rapid replacement of batteries by setting structures such as a back cover, a shell, and a battery rack. The back cover is rotated in the opposite direction on the top of the shell to separate the back cover from the range of the shell, so that the battery rack is exposed to the air. The button battery with exhausted power is pushed out and a new battery is put in, with the positive side against the positive block and the negative side against the negative block, so that the battery power can normally supply power to the controller. The back cover is then pressed against the top of the shell and rotated clockwise to combine the back cover with the shell, thereby achieving the effect of rapid installation and removal of the battery.
