Description

Technical Field

[0002] The PCB board of the smart tire receiver usually includes functional modules such as a microcontroller, a wireless communication module (such as Bluetooth, WiFi or RF module), a sensor interface, and a power management circuit. In order to prevent impurities in the air from directly corroding the circuits, chips, components, etc. on the PCB board of the smart tire receiver, it needs to be isolated from the outside world.

[0003] The external packaging structure of the intelligent tire receiver in the prior art is basically divided into two types: one is composed of an upper cover plate and a lower base plate, which is made of ABS plastic mold injection. The circuit board is embedded in the lower base plate holder, and the upper cover plate is fixed to the lower base plate by a buckle fastening device. This structure has low cost but single function; the other is composed of a rectangular metal through-hole shell and front and rear side cover plates, which are made by CNC processing technology. Different height slots are set in the metal shell to facilitate the fixing of the circuit board. The side cover plates at both ends need to reserve through holes for the wiring harness, and the sealing is achieved by sealing adhesive bonding. This structure has high cost, poor sealing reliability of the two side plates and low installation efficiency. The above two structures do not have a display module in terms of function, and cannot view the tire status in real time. When the tire has abnormal conditions such as abnormal tire pressure, excessive temperature, excessive load, and unbalanced load during the actual driving of the vehicle, it is impossible to provide early warning prompts to the driver, thereby affecting the driving safety of the vehicle.

[0004] Therefore, it is very important to study an external packaging structure for intelligent tire receivers that has a display module, is tightly sealed and easy to assemble. Utility Model Content
