Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically a tire. Background Technology

[0002] As the only core component of a vehicle in contact with the road surface, tires play a crucial role in transmitting driving force, braking force, and cushioning road impacts. Their performance directly affects vehicle driving safety and stability. With the rapid development of automotive intelligent technology, smart tires have become an important direction for industry development in order to achieve real-time monitoring of road conditions and improve driving safety. Currently, smart tires generally collect information such as road friction, bumpiness, and smoothness by equipping them with sensors, thereby providing data support for vehicle braking, anti-skid, steering adjustment, and other safety control strategies. These sensor-equipped smart tires have been gradually applied in various vehicle types, including passenger cars and commercial vehicles.

[0003] However, the existing implementations of the aforementioned smart tires still have the following problems. In terms of sensor installation and use, most adopt an external design, that is, the sensor is fixed to the tire surface by adhesive or mechanical connection. This installation method exposes the sensor directly to the external environment during vehicle operation, making it susceptible to rain, mud and sand erosion, and impact from road debris. At the same time, abnormal forces caused by tire bumps and tread friction can easily lead to sensor displacement and detachment, causing interruption of road condition monitoring. Uneven force and signal attenuation can also cause perception deviations, making it impossible to accurately capture subtle changes in road conditions. This makes it difficult to meet the needs of intelligent driving for refined monitoring of road information. In terms of sensor and tire integration compatibility, since sensors generally cannot withstand the high temperatures during the tire vulcanization process, existing technologies cannot achieve embedded integration of sensors and tires. They can only rely on external installation, which not only damages the integrity of the tire structure but also increases the later maintenance cost of the sensor, thus restricting the development process of integrated and lightweight smart tires. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a tire that improves the accuracy of road condition monitoring.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tire, comprising a tire carcass, a buffer belt assembly fixedly connected to the outer surface of the tire carcass, an inner liner fixedly installed inside the tire carcass, a bead filler component fixedly installed inside the inner liner, a sensor mounting bag fixedly installed inside the inner liner, a PE film fixedly installed on the outer surface of the sensor mounting bag, and a sensor body fixedly installed inside the sensor mounting bag.

[0006] As a preferred embodiment of this invention, a steel wire ring component is fixedly connected inside the tire carcass.

[0007] As a preferred embodiment of this invention, the outer surface of the PE film is fixedly connected with adhesive, and the inner end of the adhesive is movably connected to the outer surface of the sensor body.

[0008] In a preferred embodiment of this invention, the width of the sensor mounting bag is greater than that of the sensor body, and the depth of the sensor mounting bag is greater than that of the sensor body.

[0009] As a preferred embodiment of this invention, the PE film has high temperature resistance and is U-shaped.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model incorporates an inner liner, a sensor mounting bag, adhesive, and a sensor body. The sensor mounting bag is fixed inside the tire crown liner, isolating it from external environmental interference such as rain, mud, and tire tread friction. Its size-adaptive design, along with the adhesive securing the sensor body, ensures that the sensor remains stationary and stable during driving, guaranteeing continuous and stable operation. Furthermore, the embedded design allows the sensor to be directly attached to the core area of ​​tire stress, accurately capturing subtle signals such as friction, bumpiness, and smoothness transmitted from the road surface. This avoids the perception deviations caused by uneven stress and signal attenuation in external sensors, significantly improving the accuracy of road condition monitoring.

[0012] 2. This utility model, by setting up a bead filler component, a steel wire ring component, a tire carcass, and a buffer belt assembly, uses the tire carcass as the core support carrier. The buffer belt assembly can enhance the strength and impact resistance of the tread and reduce tread deformation. The steel wire ring component inside the tire carcass and the bead filler component inside the inner liner work together to strengthen the connection stability between the bead and the rim, preventing the bead from detaching or deforming when the tire is rotating at high speed or driving on bumpy roads. This ensures that the tire maintains stable contact with the road surface and provides a basic structural guarantee for the normal driving of the vehicle. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 2 As shown, this utility model provides a tire, including a tire carcass 3, a buffer belt assembly 5 fixedly connected to the outer surface of the tire carcass 3, an inner liner 4 fixedly installed inside the tire carcass 3, a bead filler component 1 fixedly installed inside the inner liner 4, a sensor mounting bag 6 fixedly installed inside the inner liner 4, a PE film 7 fixedly installed on the outer surface of the sensor mounting bag 6, and a sensor body 9 fixedly installed inside the sensor mounting bag 6.

[0018] The tire carcass 3 serves as the basic support structure for the tire. The buffer belt assembly 5 on its outer surface can enhance the strength and stability of the tread. The inner liner 4 is located inside the tire carcass 3 and plays an airtight role. At the same time, it provides an installation base for the bead filler component 1 and the sensor mounting bag 6. The sensor mounting bag 6 is structurally formed by the PE film 7 on its outer surface. The sensor body 9 installed inside can realize the embedding of the sensor, avoiding the problem of external sensors being prone to abnormal stress or falling off in the prior art. This lays the structural foundation for the fine perception of tire road conditions and meets the integrated design requirements of intelligent tires.

[0019] Among them, the carcass 3 is internally fixedly connected with a steel wire ring component 2.

[0020] As a key component connecting the tire and the rim, the wire bead component 2 enhances the strength and rigidity of the bead area, ensuring a stable fit between the tire and the rim during assembly and driving.

[0021] The outer surface of the PE film 7 is fixedly connected with adhesive 8, and the inner end of the adhesive 8 is movably connected to the outer surface of the sensor body 9.

[0022] The adhesive 8 is mainly used to help fix the sensor body 9, so that the sensor body 9 can be kept in a stable position inside the sensor mounting bag 6.

[0023] The width of the sensor mounting bag 6 is greater than that of the sensor body 9, and the depth of the sensor mounting bag 6 is greater than that of the sensor body 9.

[0024] The sensor mounting bag 6 is designed to match the size of the sensor body 9 to prevent the sensor body 9 from being damaged by external friction, impact, etc. due to partial exposure.

[0025] Among them, PE film 7 has high temperature resistance and is U-shaped.

[0026] The PE film 7 can withstand temperatures above 185°C. The U-shaped design of the PE film 7 is designed to fit the inner contour of the inner liner 4 to form a pocket-like space, providing a suitable mounting cavity for the sensor body 9.

[0027] Working principle and usage process of this utility model:

[0028] When a vehicle is in motion, the tire is the only component in contact with the road surface. Information about the road surface's friction, bumpiness, and smoothness is transmitted through the tire tread and tire carcass 3 to the inner liner 4 area. At this time, the sensor body 9, embedded in the sensor mounting bag 6, can directly sense these road surface action signals and convert them into electrical signals or data information. The tire constructs the sensor mounting bag 6 through a PE film 7. The PE film 7 has high temperature resistance and can maintain structural integrity in the high-temperature environment of the tire vulcanization process. After vulcanization, its U-shaped structure fits into the inner side of the inner liner 4 to form a pocket-shaped cavity. Because the sensor body 9 adopts an embedded design, it avoids the perception deviation caused by external environmental interference such as rain, mud, impact, or uneven force on external sensors. It can more accurately capture subtle changes in the road surface. The collected road surface state data can be further transmitted to the vehicle control system to provide a basis for vehicle braking, steering, anti-skid, and other safety control strategies, ultimately improving driving safety and driving stability.

[0029] The tire uses the carcass 3 as its core support carrier. Its outer surface buffer belt assembly 5 can enhance the strength and impact resistance of the tread, disperse the force transmitted by the road surface during vehicle driving, and reduce tread deformation. The steel wire ring component 2 inside the carcass 3 and the bead filler component 1 inside the inner liner 4 work together to strengthen the connection stability between the bead and the rim, prevent the bead from detaching or deforming when the tire is rotating at high speed or driving on bumpy roads, ensure that the tire maintains stable contact with the road surface, and provide basic structural protection for normal vehicle driving. At the same time, the inner liner 4 maintains stable internal tire pressure due to its airtight characteristics, and avoids abnormal air pressure from affecting driving safety and tire life.
