Benefits of technology

"The present invention is a wireless tire-pressure monitor that can be easily and securely attached to a wheel rim to monitor tire pressure or temperature. It is positioned outside of the wheel rim to prevent interference from the wheel rim and the wheel, and is not easily damaged during attaching or detaching wheel procedure. The monitor has a cylindrical body, a seal assembly, a screw, and a sensor. The seal assembly is mounted around the body on opposite sides of the wheel rim wall and abuts the flange on the body. The screw is screwed into the air passage and squeezes the seal assembly against the wheel rim wall. The sensor is mounted on the body. Therefore, the wireless tire-pressure monitor is easily and securely attached the wheel rim to detect pressure and temperature of the wheel."

Problems solved by technology

However, the conventional tire valve deteriorates from heat and the environment and eventually breaks off the wheel rim or must be replaced.
Therefore, the conventional tire valve shown in FIG. 12 could be damaged by attaching or detaching the wheel (92).

first embodiment

[0025] With reference to FIGS. 1 and 2, a wireless tire-pressure monitor in accordance with the present invention includes a body (10), a seal assembly, a screw (20), and a sensor (40).

[0026] The body (10) is cylindrical and made of metal material. The body (10) has an outside surface (11), an inside end (111), an outside end (112), exterior ribs (14), a flange (12) and an air passage (13). The exterior ribs (14) are formed on the outside surface (11) at the outside end (112). The flange (12) is formed around the outside surface (11). The air passage (13) is defined coaxially through the body (10) and has an inside end and an interior thread (131). The inside end of the air passage (13) corresponds to the inside end (111) of the body (10). The interior thread (131) is defined at the inside end of the air passage (13).

[0027] The seal assembly is positioned around the outside surface (11) of the body (10) and has an outer washer (30), a seal (31), a backing ring (33) and an inner was...

second embodiment

[0032] With reference to FIG. 5, the wireless tire-pressure monitor in accordance with the present invention further includes a tubular gasket (45) and an exterior thread (14a) formed on the outside surface (11) at the outside end (112) of a body (10). The tubular gasket (45) has an opening (451), an interior thread (452) and exterior ribs (453). The tubular gasket (45) is secured into the opening (411) in the casing (41) and screwed onto the outside surface (11) of the body (10). Since the tubular gasket (45) is screwed onto the body (10), the sensor (40) can be directly separated from the body (10) without detaching the wheel (not shown) from the wheel rim (50). The opening (451) in the tubular gasket (45) allows that the air passage (13) of the body (10) to communicate with the casing (41). Therefore, the pressure detector (421) and the temperature sensor (422) detect the tire pressure and temperature inside the wheel.

[0033] With reference to FIG. 6, a third embodiment of the wir...

Abstract

A wireless tire-pressure monitor mainly has a cylindrical body, a seal assembly, a screw and a sensor. The cylindrical body is mounted through a hole in a wheel rim wall and has an air passage, an interior thread defined in the air passage and a flange formed around the body. The seal assembly is mounted around the body on opposite sides of the wheel rim wall and abuts the flange on the body. The screw is screwed into the air passage and squeezes the seal assembly against the wheel rim wall. The sensor is mounted on the body. Therefore, the wireless tire-pressure monitor is easily and securely attached to the wheel rim to detect pressure and temperature of the wheel. Further, the sensor is positioned outside of the wheel rim to prevent the wireless detecting signals from being interfered by the wheel rim or wheel.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a wireless tire-pressure monitor, and more particularly to a wireless tire-pressure monitor that is easily and securely attached to a wheel rim and a sensor for detecting tire pressure and temperature positioned outside of the wheel rim to prevent the wireless detecting signals from being interfered by the wheel rim and the wheel. [0003] 2. Description of Related Art [0004] A tire-pressure detector or monitor is mounted on each wheel to detect the wheel's pressure or temperature. Therefore, the driver can monitor the status of each wheel to increase driving safety. [0005] With reference to FIG. 12, a conventional tire valve capable of sensing and transmitting tire pressure includes a body (80), a valve core (81), a detector (82) and a resilient outer cover (83). The body (80) has two opposite ends. The detector (82) is screwed onto one end of the body (80). The resilient outer cover ...
