[0033] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] refer to Figures 1 to 4The present application provides a burst-proof tire 1, comprising: a carcass 10, the carcass 10 comprising a crown 11 and a sidewall 12. The crown 11 is circumferentially (eg Figure 1 The axial direction of the crown 11 (as shown in the R direction) extends. Figure 1 Sidewalls 12 are provided on both sides of the tires 12 along the circumferential direction (as shown in the X direction). Figure 1 The circumferential direction R surrounds the axial direction X. The crown 11 is the main part in contact with the ground during the driving of the car, and is located between the shoulders on both sides of the tire body 10. The shoulder is the transition area between the crown 11 and the sidewall 12.

[0035] For ease of understanding, the following Figure 1 The external structure of the explosion-proof tire provided in the embodiment of the present application is introduced in detail. Figure 1 A three-dimensional diagram of a run-flat tire 1 according to an embodiment of the present application is shown.

[0036] like Figure 1 As shown in FIG. 1 , a first drainage groove 110 and a second drainage groove 111 that are interconnected are provided on the outer surface of the crown 11 (ie, the tread 1100 described later).

[0037] Specifically, the first drainage groove 110 is arranged along the circumferential direction (eg Figure 1 The second drainage groove 111 extends in the axial direction (as shown in the R direction). Figure 1 The X direction is shown in the figure.

[0038] Continue to refer Figure 1 , the first drainage groove 110 and the second drainage groove 111 respectively include a plurality of first drainage grooves 110, and the plurality of second drainage grooves 111 are arranged at equal intervals along the axial direction X, and the plurality of second drainage grooves 111 are arranged at equal intervals along the circumferential direction R. Exemplarily, 7 first drainage grooves 110 are arranged at intervals along the axial direction X, and the second drainage grooves 111 and the first drainage grooves 110 are arranged perpendicular to each other to form a mesh structure. On the one hand, it is convenient for the accumulated water to move and be discharged in the first drainage grooves 110 and the second drainage grooves 111. On the other hand, it can play an effect of increasing the friction between the explosion-proof tire 1 and the ground. It should be noted that the first drainage grooves 110 and the second drainage grooves 111 of the present application are not limited to the above-mentioned structure, and structures that can realize that the first drainage grooves 110 and the second drainage grooves 111 are evenly distributed on the outer surface of the crown 11 and are interconnected internally belong to the protection scope of the present application.

[0039] like Figure 1 As shown in FIG. 1 , the outer surface of the sidewall 12 is provided with a third drainage groove 112 .

[0040] Specifically, the third drainage groove 112 is arranged along the axial direction (eg Figure 1 For example, referring to Figure 1The third drainage groove 112 extends from the sidewall 12 of the tire body 10 to the tire shoulder, and the third drainage groove 112 is arc-shaped as a whole.

[0041] Continue to refer Figure 1 The third drainage groove 112 includes a plurality of third drainage grooves 112, which are arranged on the outer surface of the sidewall 12 at equal intervals along the circumferential direction R. Along the axial direction X, one end 1121 of the third drainage groove 112 close to the crown 11 is connected to the second drainage groove 111. Exemplarily, the plurality of third drainage grooves 112 are connected to the plurality of second drainage grooves 111 in a one-to-one correspondence, so that when the tire moves in the waterway, the water in the second drainage groove 111 can be discharged from the third drainage groove 112 through the squeezing between the ground and the carcass 10, thereby enhancing the grip of the tire.

[0042] When a car brakes suddenly, the tire of the car may burst due to severe friction between the tire and the ground, or the tire hits a sharp object, etc. Therefore, the embodiment of the present application provides a burst-proof tire 1 to solve the problem that when the car brakes, the tire rubs violently against the ground and hits a sharp object, it is easy to cause a burst.

[0043] Combine the following Figures 2 to 4 The working principle of the explosion-proof tire 1 provided in the embodiment of the present application is described in detail.

[0044] Figure 2 A cross-sectional view of a run-flat tire 1 according to an embodiment of the present application is shown. Figure 2 and Figure 3 As shown, the carcass 10 has a circumferential direction (such as Figure 2 The reinforcing member 30 extends along the circumferential direction R and is accommodated in the first chamber 20. Exemplarily, the reinforcing member 30 is made of a tensile-resistant material, such as aramid, cotton nylon, polyester or other high molecular polymer materials.

[0045] The crown 11 extends along the circumferential direction R and has a tread 1100 and a second cavity 21 extending along the circumferential direction R. The tread 1100 surrounds the second cavity 21 and extends in the radial direction (eg Figure 2 The second chamber 21 is spaced apart from the first chamber 20 on one side close to the tread 1100 , and illustratively, the circumferential direction R intersects the radial direction Y. The wear-resistant layer 40 extends along the circumferential direction R and is accommodated in the second chamber 21 .

[0046] Therefore, the embodiment of the present application can prevent the sharp object from directly puncturing the tire body 10 when the tire body 10 is pressed over the surface of the sharp object by the reinforcement member 30 disposed in the first chamber 20. In addition, the embodiment of the present application can reduce the probability of tire blowout during braking by providing the wear-resistant layer 40 disposed in the second chamber 21 to provide wear resistance to the tire body 10. In addition, the second chamber 21 is disposed on the side of the first chamber 20 that is closer to the tread 1100 in the radial direction, that is, the wear-resistant layer 40 is located on the radial Y outer side of the reinforcement member 30, and can also filter large sharp objects to prevent larger sharp objects from directly puncturing the tire body 10, thereby playing a multi-layer protection role.

[0047] In some possible implementations, reference Figure 2 The first chamber 20 includes a first portion 201 and a second portion 202 that are interconnected, and the second portion 202 is disposed in the axial direction of the first portion 201 (eg Figure 2 The first portion 201 is disposed in the tread crown 11, and the second portions 202 located on both sides of the first portion 201 are respectively disposed in the sidewalls 12 located on both sides of the tread crown 11.

[0048] refer to Figure 3 Combined with Figure 2 The reinforcement member 30 includes a first reinforcement member 301 and a second reinforcement member 302 connected to each other, and the second reinforcement member 302 is arranged in the axial direction of the first reinforcement member 301 (such as Figure 3 On both sides of the first cavity 20 (shown in the X direction), the first reinforcement 301 is accommodated in the first part 201 of the first cavity 20, and the second reinforcements 302 located on both sides of the first reinforcement 301 are respectively accommodated in the second parts 202 located on both sides of the first part 201, which can simultaneously protect the surface and both sides of the carcass 10. Exemplarily, the first part 201 is an arcuate annular cavity, the first reinforcement 301 is an arcuate annular pad, the second part 202 is a vertical annular cavity, and the second reinforcement 302 is a vertical annular pad.

[0049] It should be noted that the embodiment of the present application does not impose any specific restrictions on the connection method between the first reinforcement 301 and the second reinforcement 302. For example, it can be a fixed connection, or it can be integrally formed, as long as it can protect the surface and both side surfaces of the tire body 10 at the same time.

[0050] In some possible implementations, reference Figure 4 The wear-resistant layer 40 includes a circumferential direction (such as Figure 4 The annular net 401 is arranged inside the wear-resistant layer 40, that is, the wear-resistant layer 40 is provided with an annular net 401 extending in the radial direction (as shown in the R direction). Figure 4The projection of the annular net 401 at least partially overlaps with the projection of the tread crown 11. The annular net 401 can prevent large sharp objects from passing through and directly puncturing the tire body 10, thereby improving the anti-spiking performance of the tire.

[0051] Exemplarily, the material of the annular mesh 401 includes stainless steel, for example, the annular mesh 401 can be a wire mesh; but not limited to this, the embodiment of the present application does not impose any specific restrictions on the material of the annular mesh 401, as long as it can prevent sharp objects from directly piercing the tire body 10.

[0052] That is, on the one hand, the annular net 401 can effectively prevent large spikes from passing through, and on the other hand, the reinforcement 30 can also effectively prevent small spikes from passing through when the explosion-proof tire 1 passes over the surface of the small spikes. Therefore, the embodiment of the present application plays a multi-layer protection role through the combination of the annular net 401 of the wear-resistant layer 40 and the reinforcement 30, which can effectively prevent the tire from bursting due to hitting spikes during the driving of the vehicle.

[0053] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions.
