Abstract:
A waterproof housing without any screwing structure includes a top waterproof module, a waterproof gasket disposed on the top waterproof module, and a bottom waterproof module detachably combined with the top waterproof module. The top waterproof module has a top case, a transparent plate, and a resilient film. The top case has a touch-control window and a fingerprint hole, the transparent plate is fixed on the inner surface of the top case and entirely shields the touch-control window, and the resilient film is fixed between the inner surface of the top case and the transparent plate to shield the fingerprint hole. When a smart phone is received in the waterproof housing, the resilient film can be pressed to trigger the fingerprint function of the smart phone. The top and bottom waterproof modules are combined with each other to compress the waterproof gasket.
Abstract:
A carrier module of a tire pressure monitoring device includes a plastic carrier and a metallic tube. The plastic carrier has a trough and a tube extended from a bottom portion of the trough. The trough has an airflow channel penetratingly formed on the bottom portion thereof, and the trough is in air communication with the tube by the airflow channel The metallic tube is seamlessly formed on an inner surface of the tube of the plastic carrier. The metallic tube has an inner screw thread formed on an inner surface thereof for detachably screwing to a nozzle of a tire. Thus, by seamlessly forming the metallic tube on the inner surface of the tube of the plastic carrier, the tire pressure monitoring device of the instant disclosure has a better airproof effect and a longer service life.
