Description
Technical Field
The present invention relates to a tire and a structure of a fitting thereof; and more particularly to a tire provided with a sensor.
Background
The conventional sensors for detecting tires, such as tire pressure sensors, are mounted on the air nozzles of the rim, and measure the air pressure in the tire by means of the structure of the sensors located in the tire. After the tire pressure sensor arranged at the rim air tap senses the air pressure in the tire, the air pressure sensor can transmit the air pressure data to the outside, such as a travelling computer for receiving, judge whether the tire pressure in the tire is abnormal or not and further send out a signal for warning a driver.
The tire pressure sensor arranged at the air tap of the wheel rim can be used for detecting the air pressure in the tire because the tire pressures in all positions in the tire are the same. However, the tire pressure sensor is located near the rim and far from the tire body, so that the tire pressure sensor is suitable for measuring the tire pressure value with equal pressure at each position, and is limited in measuring other tire values.

Detailed Description
In order to more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Referring to fig. 1 to 6, a tire 100 provided with a sensor according to a preferred embodiment of the present invention includes a tire 10 and a sensor 20 combined with the tire 10, wherein the tire 10 is mounted on a vehicle in use, and when the tire 10 is mounted on the vehicle, the sensor 20 senses a physical state of the tire 10 when the vehicle is stationary, started or running.
The tire 10 has a tire body 12, an inner sidewall 121 is formed on the inner side surface of the tire body 12, the tire 10 further has a film 14, the film 14 is combined with the inner sidewall 121, the periphery of the film 14 is adhered or thermally fused to the surface of the inner sidewall 121, a flat accommodating part 141 is formed between the film 14 and the inner sidewall 121, the film 14 has a notch 142 communicated with the accommodating part 141, two sides of the notch 142 form edges which are elastic and can be closed after being unfolded, and preferably, the notch 142 is located in the middle of the film 14.
The sensor 20 is used for sensing more than one physical state parameter of the tire 10 and then wirelessly transmitting data of each physical state parameter. The sensor 20 has a housing 22 and a latch 24 coupled to the housing 22, the latch 24 includes a neck portion 241 connected to the bottom of the housing 22 and a bottom plate 242 connected to the neck portion 241, the neck portion 241 extends the edges of the two sides of the notch 142 to pass through the notch 142, so that the bottom plate 242 with a width larger than the width of the neck portion 241 and the notch 142 is received in the receiving portion 141 for positioning, and the sensor 20 is fixed to the tire inner wall 121 of the tire 10.
In the preferred embodiment of the present invention, the sensor 20 is a tire pressure detector. Preferably, the one or more physical state parameters may be selected from the group consisting of tire pressure, temperature, acceleration and sound, and the sensor 20 is provided with an air pressure sensing element, a temperature sensing element, a gyroscope, a gravity sensor or a sound sensing element according to the measured physical state parameters; each physical condition parameter of the tire 10 can be sensed nearby with the sensor 20.
When the sensor 20 senses the tire pressure and transmits the physical state parameter data to the outside wirelessly, a receiver for receiving the data from the outside, such as a vehicle computer, can determine whether the tire is burst; when the sensor 20 senses the temperature, it can determine whether the temperature of the tire 10 is too high or too low, and when the sensor 20 senses the acceleration, it can determine whether the road surface is dry or wet, the vehicle running speed, whether the tire 10 is deviated from the location by determining whether the vehicle running direction is consistent with the direction of the tire 10, or whether the tire 10 runs at an inclination angle on a downhill road section; when the sensor 20 senses the sound, the thickness of the tire 10 can be determined according to the data of the road surface reflected sound. The sensor 20 is fixed on the inner wall 121 of the tire 10, so that better and higher-accuracy data can be obtained when various physical state parameters of the tire 10 are sensed, and the safety of the road is improved by analyzing various running states of the vehicle.
Further illustrating the preferred location of the film 14 on the sidewall 121 in the preferred embodiment described above. The tire body 12 has a tread portion 122, two web portions 123 connected to both sides of the tread portion 122, and two bead portions 124 connected to the ends of the respective web portions 123, and the inner sidewall 121 covers the inner side surfaces of the tread portion 122 and the two web portions 123. In order to enable the sensor 20 to better sense the acceleration of the tire 10 when rolling, or to better sense the acceleration of the tire 10 due to the vibration of the road surface, the sensor 20 may be disposed at a position in the middle of the tread portion 122 contacting the road surface. In order to form the above structure, the rubber sheet 14 is bonded to the inner sidewall 121 at an intermediate position equidistant from the two web portions 123, so that the sensor 20 can be bonded to the inner surface of the tread portion 122 at an intermediate position through the rubber sheet 14.
Further illustrating the configuration of the tongue 24 engaging the notch 142 of the film 14 and the manner of penetration fastening in the preferred embodiment described above. Referring to fig. 3 to 5, the film 14 is a rectangular film, and the slit 142 is a slit extending linearly and formed in the middle of the film 14; the neck portion 241 of the latch 24 is a circular column, the bottom plate 242 is a long rectangular plate and is coupled to the neck portion 241 in the middle, the bottom plate 242 has two long sides 2421, the width between the two long sides 2421 is greater than the width of the neck portion 241, when the latch 24 is coupled to the notch 142, the narrow two sides of the bottom plate 242 are inserted into the receiving portion 141 from the notch 142 in a manner that the long sides 2421 are parallel to the extending direction of the notch 142 and the two sides of the notch 142 are elastically opened, and after the bottom plate 242 is inserted into the receiving portion 141, the edges of the two sides of the notch 142 are elastically clamped against the neck portion 241.
Next, as shown in fig. 4 to 5, the housing 22 and the latch 24 are rotated by 90 degrees to be in the state shown in fig. 6. In this way, the extending direction of the two long sides 2421 of the bottom plate 242 is perpendicular to the extending direction of the slit 142, and since the length of the two long sides 2421 is much longer than the opening degree of the two sides of the slit 142, the tenon 24 can be positioned in the film 14 without falling off. In addition, in order to resist the installation of the tire 10 on a vehicle, the sensor 20 is thrown away from the rubber sheet 14 by the rolling force during driving, the tangential direction of the outer side surface of the tread portion 122 where the rubber sheet 14 is provided is defined as a reference direction a, and the slit 142 is a linearly extending slit and is oriented in the same direction as the reference direction a along the linearly extending direction. In this way, the direction in which the sensor 20 is swung is mainly the extending direction of the notch 142, rather than the direction in which the two sides of the notch 142 are opened, so that the sensor 20 is preferably prevented from being separated from the notch 142.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications to the present invention as described and claimed should be included in the scope of the present invention.
