Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a tire sidewall protection device. Background Art

[0002] In the automotive field, tires are one of the key components to ensure the normal driving of vehicles. From the outside to the inside, tires can be divided into tread, shoulder, sidewall, and bead. The tread, as the outermost layer, directly contacts the ground, and achieves grip, drainage, and wear resistance through its pattern design. The hardness of the sidewall affects the comfort of the vehicle, and tire information is usually printed on it; the shoulder, as the transition area between the tread and the sidewall, is of great significance to the lateral stability, steering response, and prevention of side slip of the tire. The shoulder design is relatively tough to enhance the handling performance. The bead is responsible for contacting the wheel hub and needs to be made of solid rubber material to ensure strength and sealing.

[0003] In actual use, the sidewall of the tire plays a role in comfort and is the most fragile. When the vehicle is turning, the sidewall is easy to hit the curb and cause the tire to be damaged. The existing authorization announcement number is CN202294098U, which includes a tire body, which is assembled on various vehicles for ground rolling, an outer protective ring, which is arranged on the tire surface of the tire body, an inner protective ring, which is arranged on the tire surface of the tire body near the hub connection, and a protective member, which is arranged between the outer protective ring and the inner protective ring, and is used to protect the tire surface of the tire body. Through the cooperation of the outer protective ring and the protective member, the tire surface of the shoulder and the sidewall of the tire body is covered, so that the tire surface of the tire body is isolated from the outside world, and through the connection between the inner protective ring and the protective member, the tire surface of the sidewall of the tire body and the toe mouth is protected, which can prevent the tire from sliding and rubbing against the toe mouth of the tire body, so as to achieve good tire sidewall protection effect, avoid scratches on the tire sidewall, and ensure the service life of the tire.

[0004] The applicant has found that the prior art adopts an airbag structure, and the outer protection ring is easily affected by the airbag structure and swings up and down during driving, which accelerates the damage to the sidewall. Utility Model Content

[0021] In order to make the technical purpose, technical solution and beneficial effects of the present utility model clearer, the technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] The utility model provides a tire sidewall 3 protection device, as shown in the figure, the device includes a protection ring for sticking to the outer side of the tire sidewall 3, and the protection ring includes an adhesive layer 6, a deformation layer 7 and an inner protection layer 8 arranged in sequence from the inside to the outside. Among them, the deformation layer 7 is annular, and the deformation layer 7 is stuck to the tire sidewall 3 through the adhesive layer 6. The center line of the deformation layer 7 coincides or approximately coincides with the center line of the wheel hub 5, and the inner protection layer 8 is arranged on the deformation layer 7 at equal intervals along the circumferential direction of the deformation layer 7 (tire sidewall 3).

[0023] If multiple inner protective layers 8 are only arranged in the circumferential direction of the tire sidewall 3, although the width of the inner protective layer 8 is small, it is still large in the radial direction of the tire sidewall 3. If the deformation of the tire sidewall 3 is large, it will inevitably affect the combination of the inner protective layer 8 and the deformation layer 7. Therefore, an optional implementation is that the inner protective layer 8 is arranged in a matrix on the outside of the deformation layer 7, that is, a large inner protective layer 8 is divided into multiple small inner protective layers 8 in the radial direction of the tire to avoid damage to the inner protective layer 8 due to excessive stretching or compression.

[0024] As an optional implementation, the inner protective layer 8 is configured as a layer having flexibility and wear resistance. Specifically, the inner protective layer 8 can be configured as carbon fiber cloth, ultra-high molecular weight polyethylene cloth, aramid fiber cloth, or the like.

[0025] As an optional embodiment, the deformation layer 7 is configured as a layer that can follow the deformation of the tire sidewall 3. Specifically, the deformation layer 7 is anti-slip cloth, polyester fiber cloth, PVC cloth or polyester cloth, etc. Among the above, the anti-slip cloth, polyester fiber cloth, PVC cloth or polyester cloth are all existing technologies.

[0026] As an optional embodiment, the adhesive layer 6 is configured as a layer coated on the deformation layer 7, which is elastic and can maintain stable adhesion during dynamic movement of the tire. At the same time, in order to facilitate the removal of damage, the adhesive layer 6 is configured as a peeling glue, and the peeling glue is a rubber-based adhesive or a chloroprene adhesive. Optionally, the peeling glue can also be an adhesive of a modified polyvinyl butyral-based material coated on the inner protective layer 8. Among the above, the glue is all prior art.

[0027] The inner protective layer 8 is glued to the deformable layer 7 , and the glue layer between the inner protective layer 8 and the deformable layer 7 can also be the adhesive layer 6 .

[0028] Furthermore, it also includes an outer protective layer arranged on the outside of the inner protective layer. The outer protective layer is set to a nylon coating. The outer protective layer can effectively increase the surface smoothness and wear resistance. At the same time, nylon has good weather resistance, can resist ultraviolet radiation, rain erosion and temperature changes, and extend the service life of its inner layers.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
