Tyre prick alarm device

Abstract

The invention discloses a tyre pin-in alarm, which comprises the following parts: wireless signal launching device, wireless signal receiving device and current signal transmission belt, wherein the current signal transmission belt is set in the inner surface of tyre with even metal silver yarn printing on the surface; the adjacent metal silver yarns keep certain distance; one end of each adjacent row of metal silver yarn connects an integral, which is extended to the wireless signal launching device through wire to connect the alarming device; when the pin pierces in the inner layer of tyre, the pin touches the metal silver yarn on the current signal transmission belt to generate short-circuit, which launches the alarming signal through triggering the wireless launching device; the wireless receiving mode receives the signal to start the alarming loudspeaker, acoustic loudspeaker system or laser projector. The invention can find condition and alarm in time, which is easy to maintain and avoids the accident.

Description

Technical field: [0001] The invention relates to an alarm device, in particular to a tire nailing alarm which can give an alarm in time when a tire is pierced by a metal nail. Background technique: [0002] When the car is driving on the road, it is inevitable that nails will be stuck. When the nail pierces the inner layer of the tire, the nail will be tightly surrounded by the high-quality and elastic rubber of the tire, so the tire will It will not leak air. Generally, the tire pressure of a car will drop when the nail is nailed for 5-6 kilometers, and the pressure drop will occur. However, the existing tire alarm device is generally a pressure measuring device. If there is no obvious pressure relief, the alarm that the tire has been nailed cannot be issued, thereby causing potential safety hazards. [0003] The car tire and the inner layer itself are non-electric, non-conductive, and non-magnetic objects, and the nails inserted into the tire from the road are also non-ch...

When the nail pierces the inner layer of the tire, the nail will be tightly surrounded by the high-quality and elastic rubber of the tire, so the tire will It will not leak air. Generally, the tire pressure of a car will drop when the nail is nailed for 5-6 kilometers, and the pressure drop will occur. However, the existing tire alarm device is generally a pressure measuring device. If there is no obvious pressure relief, the alarm that the tire has been nailed cannot be issued, which will bring safety hazards

[0003] The car tire and the inner layer itself are non-electric, non-conductive, and non-magnetic objects, and the nails inserted into the tire from the road are also non-charged. In the existing tire, no short circuit and loop of current can be formed, so that it cannot pass through the circuit. Break to sense nails driven into tires
