Description

Light tire built-in tire pressure monitoring device with replaceable battery

Technical Field

The utility model belongs to the technical field of safety monitoring, a motor vehicle tire pressure monitoring devices is related to.

Background

In order to guarantee the driving safety, the automobile tire pressure monitoring (detecting) device is forcibly installed by domestic and foreign legislation, the function of the device monitors (detects) the tire pressure of the automobile tire in real time, and alarms the abnormal condition of the tire pressure through sound and light to remind a driver to predict in advance and process the occurrence of driving accidents caused by tire reasons, and the device belongs to the active safety category. The existing monitoring device with built-in sensor for monitoring (detecting) the tire pressure of the automobile tire basically adopts a fully closed structure, and a pressure sensor, a chip component PCB and a battery are sealed in a shell by using sealant. When the service life of the battery is up to the limit or the battery fails, the sensor is scrapped because the battery cannot be replaced. Not only increases the cost of automobile users, but also causes the increase of electronic garbage pollution and is irretrievable. Meanwhile, in order to make the device have a long service life, a battery with high capacity needs to be adopted, so that the volume and the weight of the product are increased.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to disclose a built-in tire pressure monitoring devices of light tire of interchangeable battery.

The utility model provides a technical problem's scheme be adopt pressure sensor, chip module PCB circuit board, battery and casing constitute tire pressure monitoring devices, pressure sensor is in the casing, there is the through-hole on the casing, pressure sensor and through-hole intercommunication, there is an annular fender in the bottom of casing, chip module PCB circuit board is lamellar circular, in annular fender, pressure sensor connects chip module PCB circuit board, there is the external screw thread annular fender outside, the battery is placed in a bottle lid-shaped battery box, the battery box has the internal thread with the external screw thread fit of annular fender, there is the negative pole piece above the battery, there is the positive plate below, the positive pole piece and the positive plate connect the positive negative pole of chip module PCB circuit board respectively, chip module PCB circuit board still is connected with the radio frequency antenna; the tyre inflating valve has one casing with one arc plate with longitudinal sliding slot, one ball with axial thread hole and with hollow screw penetrating the sliding slot, and the ball is in the bottom of the arc plate.

When the tire pressure monitoring device is installed, the tire pressure monitoring device is placed in a tire, and the hollow screw penetrates through the sliding groove and is screwed into the threaded hole of the spherical body, so that the arc-shaped plate is fixed at the position of the valve; when the battery needs to be replaced, the hollow screw is detached, the tire pressure monitoring device is taken out from the tire, the battery box is unscrewed, the battery is taken out for replacement, and the operation is reversed after a new battery is loaded, so that the replacement of the battery and the installation of the tire pressure monitoring device are completed.

A sealing gasket is further arranged between the upper surface of the pressure sensor and the shell, a hole channel is formed in the sealing gasket and corresponds to the through hole, and therefore the measuring accuracy can be improved.

The utility model discloses tire pressure monitoring device can solve the sensor and do not have the trouble and only cause whole sensor condemned problem when becoming invalid because of battery life to limit. The user does not need to find a manufacturer and a professional technician to automatically disassemble, replace and install the battery according to the required battery model. The method and the structure prolong the service life of the sensor, increase the safety guarantee, save the use cost of users and avoid the electronic garbage generated by scrapping. And the volume and the weight of the product are reduced, so that the pressure detection precision is improved.
