  • Patent number: 10583701
    Abstract: A tire pressure detector with protection shell is applied to a wheel. The wheel has a rim having an air tap and a tire mounted around the rim, with an air pressure space formed between the tire and the rim. The tire pressure detector includes a shell and a detector body. The shell is movably disposed in the air pressure space, and the detector body is disposed in a housing space of the shell. The detector body is includes a detection module for detecting the air pressure in the air pressure space, generating a pressure signal, and wirelessly transmitting the pressure signal. Therefore, by improving the structural strength of the tire pressure detector with the shell, the tire pressure detector is conveniently installed without the need of other additional tools.

  • Publication number: 20190390951
    Abstract: A tire tread detection apparatus and tire pressure detector setting apparatus with tire tread detection function are provided. The tire tread detection apparatus includes a body casing, a driving unit, a measuring member, a position member, and a sense member. The driving unit, the measuring member, and the positioning member are connected. The driving unit is applied for driving the measuring member to protrude outward from the body casing for measuring the tire tread depth of the tire. The sense member generates a measurement signal corresponding to the positioning member, such that the measurement signal indicates a tire tread depth value. Therefore, the tire tread depth is efficiently and accurately acquired.

  • Publication number: 20190360859
    Abstract: The present invention provides a vibration sensor, which comprises a circuit board having an accommodating space. A sensing assembly is disposed in the accommodating space. A recess for magnet sliding is disposed in the sensing assembly. Dispose a magnet in the recess and then dispose a coil layer on an arbitrary side or both sides of the sensing assembly. Furthermore, a lubricating layer is coated on the recess. Alternatively, the recess can be a vacuum structure or a hollow cross-sectional structure for reducing the friction between the recess and the magnet. Alternatively, the coil layer can be coated with a protective layer or multiple layers can be stacked. Without increasing the area of the sensor, the sensing on the variation of magnetic flux can be improved. Accordingly, the vibration sensor according to the present invention can achieve wideband detection of vibrations.
