  As shown in FIG. 3, when the bottom seat 2 is screwed into the tire valve and the air pressure in the tire is larger than the set value of the spring 7, the moving portion 6 is moved upward by the force that the air pressure pushes up through the moving piece 24. As a result, the concave metal fitting 61 of the moving part 6 and the conductive socket 3 are separated from each other and are turned off. On the other hand, when the air pressure in the tire is smaller than the set value of the spring 7, the concave metal fitting 61 of the moving part 6 and the conductive socket 3 come into contact with each other by the pressing force of the spring 7, and the current flows to the battery unit (button battery) 9, metal The contact piece 91, the pressure adjusting unit 8, the spring 7, the moving unit 6, the conductive socket 3, the conductive cover 4, and the alarm device 10 flow to form a conductive circuit, and the circuit board 11 of the alarm device 10 is connected to the alarm lamp 12. A light emitting diode is turned on to generate an alarm signal indicating insufficient tire pressure. At the same time, the short-range wireless communication module 13 that has detected the warning signal transmits a short-range wireless signal to the external communication terminal (smartphone), and can reliably notify the user of the warning even in the daytime when it is difficult to see.

  Further, an insulating tape (not shown) that covers a part of the upper surface of the contact portion 32 of the conductive socket 3 can be provided. Since a large contact area between the lower surface of the flat plate portion 62 of the concave metal fitting 61 and the upper surface of the contact portion 32 of the conductive socket 3 may cause malfunction, it is desirable to adjust the contact area. The means for adjusting the contact area is not limited to the insulating tape.

  Next, a tire management method using the above-described tire pressure alarm will be described. FIG. 5 is a conceptual diagram showing a mechanism of a tire management method using a tire pressure alarm.

On the other hand, dealers are always worried about how to secure stable and loyal customers and how often they receive frequent visits, but use this application. With this, it becomes possible to firmly enclose customers.
Conventionally, postcards have been used to guide customers to visit stores, but it was time-consuming and limited to vehicle inspection guidance. Even if the store visit frequency is high, it stops once a year. However, in the tire management method of the present invention, the store visit information is automatically transmitted to the customer at an appropriate time, so that it is possible to save the trouble of sending the postcard at the store. In addition, with this tire management method, a tire pressure alarm is mounted on the car, and the tire pressure naturally decreases (average 0.5% / month decrease), so an alarm is triggered by the flashing of the alarm in about three months. Therefore, the driver is encouraged to visit the store to fill the tire pressure, and the frequency of customer visits increases once every three months.

The advantages that the customer, the dealer, and the business manager enjoy are as follows.
(1) Merits for customers The tire management and vehicle management of vehicles possessing the vehicle can be performed finely, and the safety and fuel efficiency of the driver are improved. You can enjoy the detailed service of the dealer.

Increased once every 3 to 4 months from the beginning, strengthened cooperation with customers, strengthened customer engagement, leading to increased sales.
(3) Merits for business managers Sales can be increased by selling this application. Since the application is activated for the first time in combination with a tire pressure alarm device, the sales of this alarm device will expand with the sales of the application.

Further, in the tire management method described above, the following steps can be further added. That is, after the tire pressure alarm is mounted on the vehicle tire, (A) the short-range wireless communication module of the tire pressure alarm transmits a warning signal indicating that the tire pressure is insufficient to the customer communication terminal by short-range wireless transmission. And (B) a step in which notification information is transmitted from the dealer communication terminal to the customer communication terminal, and the tire management can be performed in conjunction with the steps (A) and (B). The contents of this tire management method are as follows.
In the tire management method, the tire pressure alarm notifies the smartphone application of a decrease in air pressure. Also, tire pressure history and vehicle management history can be used. It can be used as a tool that can send information to the driver in a timely manner. As a result, the driver can drive with more peace of mind.
Information from the alarm to the driver's smartphone application includes tire pressure drop information. Further, when the driver receives the information on the decrease in air pressure from the alarm device, the tire having decreased air pressure is filled with the air pressure.
This application makes it easy for the driver to receive information from the alarm and to ensure vehicle maintenance for safe vehicle operation. The driver can understand the state of pneumatic filling at a necessary timing, and it is easy to receive appropriate services from a tire dealer or a maintenance shop.

The operational flow of the tire management method is as follows.
When the tire pressure drops, the LED blinks, and the short-range wireless communication module notifies the smartphone of the tire pressure drop wirelessly. The driver receives information from the alarm and replenishes the tire pressure at the tire dealer or maintenance shop.
The driver inputs the history information to the smartphone application to complete the pneumatic filling on the smartphone screen. Since the cycle of the tire pressure drop can be predicted based on the history information, the tire pressure is filled within the cycle.
