Description

Technical Field

[0001] This utility model relates to the field of tire internal support bodies, specifically a self-cooling tire internal support body device. Background Technology

[0002] Tire support structures are a technology used to enhance tire performance and safety, especially in the event of tire loss of pressure or a blowout, providing additional support to ensure continued safe driving. The background of this technology can be traced back to the limitations of traditional tires. Traditional pneumatic tires rely on internal air pressure to maintain their shape and load-bearing capacity, but when subjected to a puncture, leak, or blowout, the tire quickly loses support, leading to loss of vehicle control and increasing the risk of accidents. To address this problem, tire support structure technology was developed.

[0003] When a vehicle is in motion, the tire contacts and rolls with the ground, generating friction between the inner support structure, the tire's interior, and the rim. In the event of tire depressurization or a blowout, the inner support structure directly bears the vehicle's weight, increasing the contact area with the tire's interior and intensifying friction, leading to rapid heat accumulation. If not cooled promptly, excessively high temperatures will accelerate material aging and may even cause the inner support structure to deform or fail.

[0004] However, existing technologies lack devices for cooling the tire's internal support structure, making it difficult to cool the internal support structure in high-temperature environments and after a tire blowout. Therefore, a self-cooling tire internal support structure device is proposed. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a self-cooling tire internal support device.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] This utility model discloses a self-cooling tire inner support device, comprising several inner support members, which are connected end to end to form an annular inner support body. Several through holes are opened on both sides of the inner support body, and the several through holes are arranged in a ring array. The several through holes are inclined in the same direction along their arrangement direction. High-pressure air zone and low-pressure air zone are formed on both sides of the through holes respectively. As the inner support body rotates, air flows from the high-pressure zone to the low-pressure zone of the through holes and carries away heat.

[0008] Furthermore, the through hole has an elongated linear structure, and the elongated linear through hole is arranged along the outer ring side of the inner support towards the inner ring side.

[0009] Furthermore, a large hole and a small hole are formed on both sides of the through hole, and air flows along the side of the small hole toward the side of the large hole.

[0010] Furthermore, the through hole has a wavy shape on the radial cross-section of the inner support.

[0011] Furthermore, the inner wall of the through hole transitions from the large hole to the small hole with a circular arc.

[0012] Furthermore, the inclination angle of the through hole is 5°~25°.

[0013] The beneficial effects of this utility model are as follows: By opening through holes on the side wall of the inner support body, which is its radial surface, and by setting the through holes at an angle, with each through hole tilted towards the direction of the previous through hole, when the vehicle is running with a flat tire, the outside air is squeezed into the inner support body position inside the tire after being crushed by the tire. When the tire drives the inner support body to continue rotating at high speed, the partition between any two tilted through holes forms a structure similar to a fan blade. When the tire drives the inner support body to rotate in one direction, it will drive the airflow from the high-pressure area of ​​the through hole to the low-pressure area, forming a fan-like effect. Furthermore, the through holes continuously draw in and expel airflow. During the continuous rotation of the inner support body driven by the tire, the airflow flowing through the tilted through holes will carry away a large amount of heat, reducing the heat accumulation on the inner support body, so that the inner support body can achieve self-cooling after the tire blows out as the tire rotates.

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] like Figures 1-3As shown, the present invention provides a self-cooling tire inner support device, which includes several inner support members. The several inner support members are connected end to end to form an annular inner support body 1. Several through holes 2 are opened on both sides of the inner support body 1. The several through holes 2 are arranged in a ring array. The several through holes 2 are inclined in the same direction along their arrangement direction. High pressure zone and low pressure zone are formed on both sides of the through holes 2 respectively. Air flows from the high pressure zone to the low pressure zone of the through holes 2 as the inner support body 1 rotates and carries away heat.

[0021] When a vehicle is in motion, the tire contacts and rolls with the ground, generating friction between the inner support 1, the tire's interior, and the rim. In the event of tire depressurization or a blowout, the inner support 1 directly bears the vehicle's weight, increasing the contact area with the tire's interior and intensifying friction, leading to rapid heat accumulation. If not cooled in time, excessively high temperatures will accelerate material aging and may even cause the inner support 1 to deform or fail. However, current technology lacks a device for cooling the tire's inner support 1, making it difficult to cool it in high-temperature environments and after a tire blowout.

[0022] To enable the inner support body 1 to achieve self-cooling through airflow after a tire blowout, through holes 2 are made in the side wall of the inner support body 1, which is its radial surface. The through holes 2 are inclined, each oriented towards the previous one. When the vehicle is deflating, external air is compressed by the tire and forced into the inner support body 1. As the tire drives the inner support body 1 to continue rotating at high speed, the partition between any two inclined through holes 2 forms a fan-like structure. When the tire drives the inner support body 1 to rotate in one direction, it drives airflow from the high-pressure area of ​​the through holes 2 to the low-pressure area, creating a fan-like effect. As the inner support body 1 rotates, the inner wall of the inclined through holes 2 does work on the air, drawing air in from the intake side. Because air is drawn in, the air pressure on the intake side decreases, creating a low-pressure area. The inner wall of the inclined through holes 2 compresses the air and accelerates it towards the exhaust side, causing the air pressure on the exhaust side to increase, creating a high-pressure area. The principle is as follows: Under centrifugal force, the inclined through-holes 2 of the rotating inner support 1 push air outwards, and the airflow is unidirectional according to the inclination direction of the through-holes 2. High-pressure and low-pressure zones are formed according to the direction of airflow, and airflow is continuously drawn in and discharged through the through-holes 2. During the continuous rotation of the inner support 1 driven by the tire, the airflow flowing through the inclined through-holes 2 carries away a large amount of heat, reducing heat accumulation on the inner support 1. This allows the inner support 1 to self-cool itself after a tire blowout as the tire rotates. Simultaneously, because the through-holes 2 are arranged in a ring array, the heat dissipation efficiency is the same in different areas of the inner support 1, preventing differences in heat dissipation efficiency in different areas of the inner support 1 that could lead to differences in metal fatigue strength at different temperatures.

[0023] In order to make the heat dissipation of the inner support body 1 faster, in one embodiment, the through hole 2 is in the form of a long strip-shaped structure, and the long strip-shaped through hole 2 is arranged along the outer ring side to the inner ring side of the inner support body 1. Since the inner support body 1 has a certain thickness, the long strip-shaped through hole 2 has the largest contact area with the air. When the air flows through the through hole 2, more heat is taken away, and the heat dissipation effect generated by the inner support body 1 as the tire rotates after a tire blowout is better.

[0024] Furthermore, a large hole 21 and a small hole 22 are formed on both sides of the through hole 2, respectively. Air flows from the small hole 22 side towards the large hole 21 side. Based on the tilt angle of the through hole 2 in the above embodiment, the air flows unidirectionally within the through hole 2, resulting in higher air pressure at the large hole 21. Air flows from the high-pressure area to the low-pressure area, and then flows out from the large hole 21. Furthermore, according to the Venturi effect, the cross-sectional change from the small hole 22 to the large hole 21 accelerates the airflow, further promoting the airflow entering from the small hole 22 and exiting from the large hole 21. Through these principles, the airflow speed within the through hole 2 is accelerated, improving the heat dissipation efficiency of the inner support 1.

[0025] Since the airflow inside a tire may not be smooth after a tire blowout, in order to optimize the airflow efficiency, in one embodiment, the through hole 2 is wavy in the radial section of the inner support 1, so that the inner wall of the through hole 2 is also wavy; therefore, a wavy partition is formed between the inner walls of the two through holes 2, which acts like a fan blade.

[0026] The corrugated baffle can guide airflow more smoothly through the baffle, reduce the generation of turbulence and eddies, and improve airflow efficiency. The corrugated design can increase the contact area with the airflow without increasing the length of the fan blades, thereby increasing the air volume. The corrugated fan blades can reduce airflow separation and the generation of turbulence, as well as change the natural frequency of the fan blades, avoiding resonance with the airflow or other components, thereby reducing noise caused by turbulence.

[0027] Since the inner support 1 needs to bear the weight of the vehicle after a tire blowout, in order to reduce the impact of other factors on the structural strength of the inner support 1, the structure of the corrugated baffle can better resist the vibration caused by airflow, thereby improving the stability and durability of the baffle, and dispersing the stress on the baffle when it is under high-speed rotation and pressure, reducing the risk of fatigue damage.

[0028] In one embodiment, the inner wall of the through hole 2, from the large hole 21 to the small hole 22, is rounded; this allows the airflow to flow more smoothly and improves the airflow efficiency.

[0029] In one embodiment, the tilt angle of the through hole 2 is 5° to 25°. The tilt angle of the through hole 2 is designed so that the partition directly above the through hole 2 can act like a fan blade when rotating, thereby driving airflow and improving heat dissipation efficiency. However, the tilt angle of the through hole 2 and the partition is not necessarily better the larger it is. If the tilt angle of the through hole 2 is too large, it may result in insufficient support force of the partition for the inner support body 1 under greater pressure after a tire blowout, affecting the structural strength of the inner support body 1. Therefore, it is necessary to control the tilt angle of the through hole 2 and the partition within a reasonable range so that it can drive airflow when rotating and provide sufficient structural strength for other parts of the inner support body 1, thereby improving safety during use.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
