Patent Application
20200148017
The present application claims the benefit of Chinese Patent Application No. 201821850820.X filed on Nov. 9, 2018, the contents of which are incorporated herein by reference in its entirety.
The present disclosure relates to an automobile accessory, and in particular to a universal tire pressure sensor device which can use a metal air valve and a rubber air valve and can adjust angles.
An automobile tire pressure sensor is an accessory that is often installed on automobiles. When an original part is damaged or out of power, it is necessary to replace with a replacement part. There are two types of tire pressure sensors available in the market. One is applied for angle adjustable metal air valve and the other is applied for rubber air valve. These two are not universal. The problem that arises is that the sensor can only be installed with a metal air valve, but cannot be replaced by a rubber air valve; or the sensor can only be installed with a rubber air valve, but cannot be replaced by a metal air valve. Hence, maintenance becomes difficult because corresponding matching components must be used. In order to maintain the consistency with the original air valve (metal or rubber), a maintenance personnel must prepare an inventory of both metal and rubber sensors. This increases pressure on inventory and capital cost for the agent.
In view of the existing deficiencies, the present disclosure provides a universal tire pressure sensor device which can use both a metal valve and a rubber valve and can adjust angles.
The technical solution adopted by the present disclosure to solve the technical problem is as follows:
A tire pressure sensor device may include a housing mounted with a sensor body, an air valve, and a connecting portion extending from the housing for mounting the air valve. The connecting portion may be provided with a first groove in a shape of a spherical cap, and a bottom surface of the first groove may be provided with a strip-shaped through-hole penetrating through a bottom portion of the first groove. A plastic plug may be detachably mounted on and mating with the first groove. A top portion of the plastic plug may be provided with a second groove. The plastic plug may be further provided with a circular through-hole penetrating through a bottom surface of the second groove. The air valve may be fixedly connected to the housing by screws passing through the strip-shaped through-hole, or the strip-shaped through-hole and the circular through-hole.
Preferably, a bottom portion of the plastic plug may extend around the circular through-hole to form an extending portion that is fittingly embedded into the strip-shaped through-hole, and the circular through-hole may extend through the extending portion.
Preferably, the second groove may be an oval-shaped groove.
Preferably, the first groove may be provided with a flat surface on an inner wall corresponding to a long side direction of the strip-shaped through-hole, and a surface of the plastic plug that corresponds to the flat surface may also be planar in shape.
Preferably, the connecting portion may be a column body having a semi-circular ring-shaped cross section.
Preferably, the plastic plug may be in the shape of a spherical cap, and a height of the spherical cap may be greater than a radius of the spherical cap.
Preferably, the plastic plug may be an elastic deformable plastic plug, or the plastic plug may be made of hard plastic.
The beneficial effects of the present disclosure are as follows:
In the present disclosure, the first groove has the shape of a spherical cap and can facilitate angle adjustment and installation of a metal air valve, and the strip-shaped through-hole can facilitate fixing of a screw. The plastic plug is configured to allow a rubber air valve to be mounted on the housing, which can be fitted with either a metal air valve or a rubber air valve. The angle of installation can also be adjusted. This can solve the problem that the conventional tire pressure sensor is not universal for angle adjustable metal and rubber air valves.
