Description

Tires equipped with sensors (3)

The invention relates to a structure of a tire and its accessories; in particular, it relates to a tire provided with a sensor.

Existing sensors commonly used to detect tires, such as tire pressure sensors, are combined with air nozzles of rims to measure the air pressure in the tires by virtue of the structure in which the sensors are located in the tires. After the aforementioned tire pressure sensor installed on the rim valve senses the air pressure in the tire, it will transmit the air pressure data to the outside, such as the trip computer, and judge whether the tire pressure in the tire is abnormal, and then issue a warning signal to the driver signal.

The above-mentioned tire pressure sensor located at the rim air nozzle can be used to detect the air pressure inside the tire because the tire pressure is the same everywhere inside the tire. However, the position of this kind of tire pressure sensor is close to the wheel rim and far from the tire body, which is more suitable for measuring the tire pressure values with equal pressure everywhere, and is relatively limited in measuring the values of other tires.

In view of this, the object of the present invention is to provide a structure in which the sensor is integrated inside the tire, so that the physical state parameters of the tire can be better sensed by the sensor adjacent to the tire itself.

In order to achieve the purpose of the above invention, the present invention provides a tire provided with a sensor, which includes a tire and a sensor combined inside the tire.

The tire 10 also has a film 14, which is combined with the tire inner wall 121, and the surrounding of the film 14 is pasted or heated. Fused on the surface of the inner wall 121 of the tire, a flat receiving portion 141 is formed between the film 14 and the inner wall 121 of the tire. The side forms an elastic edge that can be closed after stretching. Preferably, the cutout 142 is located in the middle of the film 14 .

The sensor 20 is used to sense more than one physical state parameter of the tire 10 , and then wirelessly transmit data of each physical state parameter to the outside. The sensor 20 has a housing 22 and a tenon 24 combined with the housing 22. The tenon 24 includes a neck 241 connected to the bottom of the housing 22 and a bottom plate 242 connected to the neck 241. The neck 241 spreads the edges on both sides of the cutout 142 and passes through the cutout 142, so that the bottom plate 242, which is wider than the neck portion 241 and the cutout 142, is accommodated in the accommodating portion 141 for positioning, and the sensor 20 is fixed to the tire The tire inner wall 121 of 10.

In the above preferred embodiment of the present invention, the sensor 20 is a tire pressure detector. Preferably, the more than one physical state parameter may be selected from the group consisting of tire pressure, temperature, acceleration and sound. With the difference of the measured physical state parameter, the sensor 20 is provided with Air pressure sensing element, temperature sensing element, gyroscope, gravity sensor or sound sensing element; the sensor 20 can sense various physical state parameters of the tire 10 nearby.

When the sensor 20 senses the tire pressure and wirelessly transmits the physical state parameter data to the outside, the external receiver receiving the data, such as the vehicle’s trip computer, can use this to determine whether the tire is blown out; when the sensor 20 senses When the temperature is high, it can be judged whether the temperature of the tire 10 is too high or too low. When the sensor 20 senses the acceleration, it can be judged by the vibration of the tire 10 running on the road whether the road is dry or wet, the speed of the vehicle, Whether the tire 10 deviates from its positioning or the inclination angle of the tire 10 on the uphill and downhill sections can be judged by whether the driving direction of the vehicle is consistent with the direction of the tire 10; when the sensor 20 senses the sound, the data of the sound can be reflected by the road surface The thickness of the tire 10 is judged. In the present invention, the sensor 20 is fixed on the inner wall 121 of the tire 10. When sensing various physical state parameters of the tire 10, better data with higher accuracy can be obtained, so as to analyze various aspects of vehicle driving. The state enhances the safety of the road.

The preferred position of setting the film 14 on the tire inner wall 121 in the above-mentioned preferred embodiment is further described. The tire body 12 has a tread portion 122, two belly portions 123 connected to both sides of the tread portion 122, and two bead portions 124 respectively connected to the ends of the belly portions 123. The tire inner wall 121 covers the tread portion 122 and the inner side of the abdomen 123 of the second child. In order to enable the sensor 20 to better sense the acceleration of the tire 10 when it rolls, or to better sense the acceleration of the tire 10 due to road vibration, the position of the sensor 20 can be set at the point of contact with the road surface. The tread portion 122 is in the middle. In order to form the above structure, the film 14 is bonded to the middle of the tire inner wall 121 at an equidistant distance from the second belly 123 so that the sensor 20 can pass through the film 14 and be bonded to the middle of the inner surface of the tread portion 122 Location.

Further explain the structure of the tenon 24 matching the cutout 142 of the film 14 in the above-mentioned preferred embodiment and the way of penetration and fixing. 3 to 5, the film 14 is a rectangular film, the slit 142 is a linearly extending slit and is formed in the middle of the film 14; the neck 241 of the tenon 24 is a circular cylinder, The bottom plate 242 is a long rectangular plate and is combined with the neck 241 in the middle. The bottom plate 242 has two long sides 2421, and the width between the two long sides 2421 is greater than the width of the neck 241. When the tenon 24 When combined with the slit 142, the long side 2421 is first parallel to the direction in which the slit 142 extends, and the narrower sides of the bottom plate 242 are inserted into the slit 142 by elastically opening both sides of the slit 142. In the receiving portion 141 , when the bottom plate 242 is put into the receiving portion 141 , the edges on both sides of the cutout 142 will elastically clamp against the neck portion 241 .

Next, as shown in FIG. 4 to FIG. 5 , the housing 22 together with the tenon 24 is rotated by 90 degrees to become the state shown in FIG. 6 . In this way, the direction in which the two long sides 2421 of the bottom plate 242 extend is perpendicular to the direction in which the slit 142 extends. At this time, since the length of the two long sides 2421 is far greater than the degree that the two sides of the slit 142 can be opened, the tenon 24 can be better. It is positioned at the inside of the film 14 and will not fall off. In addition, in order to resist the installation of the tire 10 on the vehicle, the rolling force of the sensor 20 will be thrown away from the film 14 during driving, and the tangential direction of the outer surface of the tread portion 122 where the film 14 is provided is defined as a reference direction A, the notch 142 is a slit extending straight, and the direction along the straight line is the same as the reference direction A.
