Description

Tire wear reminder structure

The invention relates to a tire wear reminding structure, in particular to a rib of a rubber material having different hardness and color in the tire when the tire is depleted to a certain standard, which can promptly indicate the timing of the tire wear and need to be replaced, and at the same time Vibration and abnormal sound prompts to ensure the driving safety effect.

According to the tire, the tire is a circular rubber product that is mounted on the vehicle and can roll on the ground. Since the tire must bear various deformation, load, force and high and low temperature effects while the vehicle is running, the tire must have high bearing performance. , traction performance, cushioning performance, high wear resistance, flex resistance, grip, low rolling resistance and heat generation.

In terms of grip, the tire tread is in contact with the ground, which is the main basis for vehicle grip. Especially when driving in rainy weather or wet road, good tires will have good wetland grip performance and also represent the vehicle. It can drive safely; the performance of the grip has a direct and absolute correlation with the pattern on the surface of the tire. The pattern on the surface of the tire increases the friction between the surface of the tire and the road surface to prevent the tire from slipping, but it will cause long-term driving. Tire loss, the tire tread is getting thinner, the tire's grip performance is reduced, the driver must replace the tire in time, otherwise it will be easy to slip, which will affect the safety of driving and endanger the life and property of others and others, so the driver Need to pay attention to the tire wear situation.

Usually, the driver checks the degree of tire wear by visual inspection. Therefore, the judgment standard of wear varies from person to person. Since there is no certain standard of tire wear judgment, the tire grip performance is often deteriorated and the driver still drives on the road. Therefore, a car accident occurred.

Therefore, the relevant industry has developed a tire structure that can be prompted when the tire wear is to a certain extent, in view of the fact that there is no standard to limit the degree of wear of the tire track to be replaced, and there is a concern about driving safety.

For example, the new patent No. M411357 of China is a puncture-proof tire and a tire with a wear state. The puncture-proof tire mainly comprises: a tire body, and the tire body further comprises a plurality of radial distribution warning layers. Each warning layer is composed of puncture-proof materials, and the warning layers have different color displays, and the display of different colors of the warning layers is provided for the rider to clearly understand the current degree of tire wear and as Remind and warn about the role of tire replacement.

Another example is the tire wear mark new patent of China No. M466033, which uses the tire tread as a reference surface, with the center of the tire as a central axis, extending inwardly from the tire tire, and different in the tire tread. One or several tire wear marks are embedded in the depth and at different positions. The tire wear marks may be of the same shape and the same color, or may be composed of different shapes and different colors. During the use of the tire, the tires are worn out due to the tires. The tire wear mark embedded in the above-mentioned tires will be exposed in order according to the depth of the embedded, and provide a hint of the degree of wear of the tire, thereby achieving the purpose of warning that the user needs to replace the tire, so as to improve the driving safety of the vehicle. .

Another example is China's new certificate No. M436578, which is a tire with a color warning degree of wear. It places a colored layer between the inner carcass and the surface of the carcass. The surface of the tire skin is worn away before the tire wears to the possibility of causing danger to the vehicle, and the colored tire layer is exposed after the surface of the tire skin is worn away, and has a function of alerting the user to replace the tire.

However, the above-mentioned new patent No. M411357, the new patent No. M466033, and the new patent No. M436578 are all developed for visual warnings, and no other warning effects are provided. If the user does not observe carefully, there will still be tire wear. The situation that needs to be replaced but the user is still unaware of it, and still driving on the road jeopardizes the safety of driving.

Now, the present inventors have further developed the present invention in view of the lack of the conventional tire described above after actual use.

The main object of the present invention is to provide a tire wear reminding structure, which is based on the prompt of replacement after tire wear in daily life, and the safety check of the vehicle user before driving is based on, but after the inspection, the basis There is no clear regulation on the state of the tire after the wear is required to be replaced. For the convenience and user's use habits, the internal structure of the tire provided by the present invention solves the requirement of replacing the tire on time, and solves the previous standard of tire wear replacement. Blur zone. When the tire is depleted to a certain standard, the rib rubber with different hardness in the tire is exposed, and the effect of vibration and abnormal sound is generated when driving.

The above main object of the present invention is achieved by the following specific technical means:

A tire wear reminding structure comprises a tire inner layer, a hard warning layer and a tire body outer layer; the hard warning layer is disposed on the inner surface of the tire body, and the surface of the hard warning layer is provided with at least one rib. The outer surface of the tire body is disposed on the surface of the hard warning layer, so that the hard warning layer and the rib are embedded inside the outer layer of the tire body, and the hard warning layer and the outer layer of the tire body are made of rubber materials with different hardness and different colors. The hardness of the hard warning layer is greater than the hardness of the outer layer of the tire body; accordingly, in addition to the color of the hard warning layer and the outer layer of the tire body, the user is reminded that the tire has been worn to a state that needs to be replaced, and at the same time The ribs of the material hardness are exposed, and the vibration and sound generated during driving are different from the outer layer of the tire body contacting the ground, and further reminds the user that the tire needs to be replaced by the sense of body and sound.

The tire wear warning structure as described above, wherein when the plurality of ribs are provided on the surface of the hard warning layer, the ribs are disposed at equal angular intervals.
