[0001] The invention discloses a tire blowout safety rim, and particularly relates to the technical field of automobile parts. Background Art

[0002] In recent years, my country's automobile industry has developed rapidly, which has provided a broad market space for the automobile wheel industry. At the same time, with the improvement of people's living standards, people have put forward higher requirements on the safety of automobile wheels.

[0003] We know that when a car is driving fast, a tire burst can easily cause a major safety accident. In order to improve the safety of car wheels and avoid safety accidents, technicians in the car wheel industry have also done diligent research.

[0004] Most of the existing tire explosion-proof rings are fixed to the outer wall of the automobile rim by bolt connection. When the tire rotates for a long time, the tire explosion-proof ring is easily disconnected due to acceleration or braking, causing the explosion-proof function to fail. Summary of the invention

[0005] The purpose of the present invention is to provide a tire blowout safety rim to solve the problem proposed in the above background technology that the existing tire blowout-proof ring is mostly fixed to the outer wall of the automobile rim by bolt connection. When the tire rotates for a long time, the tire blowout-proof ring is very likely to break due to acceleration or braking, resulting in failure of the blowout-proof function.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tire blowout safety rim, comprising a rim, wherein the left and right outer walls of the rim are fixedly mounted with retaining rings, a rim groove is formed on the right portion of the outer wall of the rim, limiting grooves are uniformly formed on the circumference of the inner cavity bottom wall of the rim groove, a tire blowout-proof ring is clamped in the inner cavity of the rim groove, the inner wall of the rim groove contacts the outer wall of the tire blowout-proof ring, support sheets are uniformly fixedly mounted on the outer wall of the tire blowout-proof ring, support pads are uniformly fixedly mounted on the inner wall of the tire blowout-proof ring, and support feet are uniformly fixedly mounted on the inner wall of the tire blowout-proof ring, and the support feet are located in the inner cavity of the limiting groove.

[0007] Preferably, the tire explosion-proof ring, the support plate and the support foot are integrally injection molded.

[0008] Preferably, the thickness of the supporting foot is the same as the depth of the limiting groove.

[0009] Preferably, the end of the support sheet is provided with an arc.

[0010] Preferably, a first friction surface is provided on the inner circumference of the rim groove.

[0011] Preferably, the left and right outer walls of the tire explosion-proof ring are both provided with a second friction surface.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1) The tire explosion-proof ring, support plate and support pad in this device are integrally formed by injection molding. The tire explosion-proof ring is sleeved in the inner cavity of the wheel rim groove. During the acceleration or deceleration of the car, the tire explosion-proof ring is not easy to break;

[0014] 2) The device has a limit groove on the inner wall of the rim groove, and a support foot is provided on the inner wall of the tire explosion-proof ring. The support foot is engaged with the limit groove to increase the friction between the rim and the tire explosion-proof ring, so as to avoid the friction between the rim and the tire explosion-proof ring being too small, so that the wheel hub cannot transmit effective driving force, steering force and braking force through the tire explosion-proof ring when the tire bursts;

[0015] 3) The device is provided with a support sheet on the outer wall of the tire explosion-proof ring, and the friction between the tire explosion-proof ring and the tire is increased by the support sheet to avoid too small friction between the tire and the tire explosion-proof ring. When the tire bursts, the wheel hub cannot transmit effective driving force, steering force and braking force to the tire through the tire explosion-proof ring. The device has a simple structure and is easy to use. It can effectively avoid the occurrence of the tire explosion-proof ring disconnection phenomenon and effectively increase the friction between the tire explosion-proof ring and the tire and the rim.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present invention provides a tire explosion safety rim, which effectively avoids the occurrence of the tire explosion-proof ring disconnection phenomenon and effectively improves the friction between the tire explosion-proof ring and the tire and the rim. Figure 1 , Figure 2 and Figure 4 , including a rim 100, a retaining ring 110 is fixedly installed on the left and right outer walls of the rim 100, a rim groove 120 is opened on the right part of the outer wall of the rim 100, the rim groove 120 is used to install the tire explosion-proof ring 200, and the bottom wall of the rim groove 120 is uniformly opened with limiting grooves 130 on the circumference, and the limiting grooves 130 are used to clamp with the supporting pads 220 on the inner wall of the tire explosion-proof ring 200;

[0023] See also Figure 2 and Figure 3 The inner cavity of the wheel rim groove 120 is clamped with a tire explosion-proof ring 200, the inner wall of the wheel rim groove 120 contacts the outer wall of the tire explosion-proof ring 200, the outer wall circumference of the tire explosion-proof ring 200 is evenly fixed with a support sheet 210, the inner wall circumference of the tire explosion-proof ring 200 is evenly fixed with a support foot 220, the support foot 220 is located in the inner cavity of the limiting groove 130, the tire explosion-proof ring 200, the support sheet 210 and the support foot 220 are all rubber structures, the tire explosion-proof ring 200, the support sheet 210 and the support foot 220 are all rubber structures, and the tire explosion-proof ring 200 is evenly fixed with a support sheet 210. The ring 200 effectively fills the inner diameter difference of the rim 100, preventing the tire from rolling into the groove bottom or detaching from the rim 100 after the tire loses pressure, and uses the deflated tire to effectively support and form a rubber pad to prevent the metal rim 100 from directly touching the bottom and slipping. The support sheet 210 on the outer wall of the tire explosion-proof ring 200 forms a reliable gear structure inside the rim 100, which is tightly engaged with the deflated tire. The wheel in the crawler drive mode can also normally transmit driving force, steering force and braking force to the ground after the tire bursts.
