Description

Tire monitoring device

The present invention relates to a tire monitoring device, and more particularly to a tire monitoring device that can monitor tire wear conditions.

The regulations on the reduction of accidents and pedestrian safety of steam locomotives in the world are increasingly strengthened. At present, the US regulations have clearly regulated that the vehicle must have a built-in tire pressure monitoring system (TPMS), which can be used to tires when the car is moving. Do real-time automatic monitoring, when the tire pressure is too low or the temperature is too high, send a warning signal to the driver, inform the driver to help the tires to pump or replace the tires to ensure safe driving.

In addition to the temperature and pressure of the tire, the wear state of the tire is also an important criterion for evaluating whether a tire is usable. Once the tire is excessively worn, it may cause insufficient tire grip, poor drainage, high tire temperature, and even severe cases. Puncture.

In order to monitor the wear state of the tire, Patent No. 200639082 discloses a system and method that can be applied to monitor the wear state of the tire by embedding a uniquely identified radio frequency identification (RFID) tag in the tire, and when the RFID tag is damaged, it indicates that the tire is The wear condition has reached the standard for tire replacement. Its RFID tags can be distributed at different depths of the tire or across the same depth of the tire to determine the wear state of the tire.

However, although RFID tags have many advantages, their high cost is a major drawback that they cannot be widely used in the market. Except for the high cost of RFID tags themselves, in order to detect the signals transmitted by RFID tags, it is necessary to detect the signals transmitted by RFID tags. With a strong sensing device to periodically detect the signal emitted by the RFID tag, the strong sensing device has a high energy consumption, and the signal emitted by the RFID tag is easily interfered by other electromagnetic fields such as car parts, which is prone to misjudgment.

Patent No. I317703 discloses a mechanism for detecting a carcass and a tread of a tire by using a photoelectric element. The photoelectric element is embedded in the tire, and when the tire is worn to a certain extent, a crack is generated, and external light is transmitted through the crack to the photoelectric element. The component receives light and generates a signal to warn the driver that the tire should be replaced. However, the photovoltaic element also has a high cost. In addition, when the tire is worn to a certain extent, it may wear together with the photovoltaic element before the crack is generated, and the photoelectric element is damaged, and the driver's effect cannot be demonstrated.

Accordingly, it is an object of the present invention to provide a tire monitoring apparatus that monitors tire wear conditions and that can substantially reduce costs and reduce the likelihood of misjudgment.

One aspect of the present invention provides a tire monitoring apparatus that is disposed on a tire that includes a tread on which a plurality of grooves are disposed, and that the groove has a depth relative to the tire mask. The tire monitoring device comprises a wire and a controller electrically connected to form a circuit. The wire is disposed on the tire and has a wear section. The distance between the wear section and the tread is less than the depth of the groove, and the tire is worn to The position of the wire wear section will break the wear section and cause the circuit to form an open circuit to judge the wear state of the tire.

In accordance with an embodiment of the invention, the controller includes a sensing element that senses the temperature and/or pressure of the tire.

According to an embodiment of the invention, the controller includes a signal processing component for integrating and transmitting the status signal of the tire.

According to an embodiment of the invention, the controller is a Tire Pressure Monitoring System (TPMS).

According to an embodiment of the invention, a display is further included for displaying the wear state, temperature or pressure of the tire.

The invention utilizes a circuit formed by a wire and a controller to monitor the wear state of the tire. When the tire wears to a certain extent, the wire wear section is broken and the circuit is broken, and the tire monitoring device sends a signal to the driver to Warn the driver to change the tires. The consumable-wire used in the present invention is cheaper and easier to manufacture than the conventional RFID tag and photoelectric component, and can greatly reduce the production cost. In addition, it can be integrated with the commercially available tire pressure monitoring system (TPMS), while monitoring the wear status, temperature and pressure of the tires, allowing the driver to obtain multiple guarantees at the most economical cost.
