[0029] The terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, in addition to including the listed elements, other elements not explicitly listed can also be included.

[0030] Please refer to Figure 1 , Figure 2 The first aspect of the embodiments of the present application provides an emergency tire repair patch for emergency repair of the tire of an automobile. It should be noted that the repair of the tire referred to herein means temporary repair of the tire, and the purpose is to ensure that the automobile can continue to travel at a certain speed (for example, 60km / h~90km / h) within a certain time, so as to drive off the main road or to the nearest maintenance site for professional maintenance.

[0031] In the embodiment, the emergency tire repair patch comprises a protective layer 1 and a rubber patch 2, wherein the rubber patch 2 is attached to the protective layer 1. Specifically, the rubber patch 2 comprises a wear-resistant layer 21 and an adhesive layer 22, wherein the adhesive layer 22 is attached between the protective layer 1 and the wear-resistant layer 21. Thus, when the tire is punctured due to wear, aging, or the puncture of sharp objects such as nails, glass, stones, etc. during driving, the rubber patch 2 is first torn off from the protective layer 1, and then the adhesive layer 22 of the rubber patch 2 is adhered and filled in the damaged area on the outer surface of the tire, which facilitates the driver to repair the tire in emergency and improves the safety of the personnel and the vehicle during driving. Compared with the way of replacing the spare tire or waiting for road rescue, the utility model is beneficial to greatly shorten the time consumption of tire repair and timely reduce the impact caused by tire puncture. It is worth mentioning that the damage on the outer surface of the tire refers to the damage on the tire tread, especially the damage in the pattern groove area.

[0032] Since the pattern groove on the outer surface of the tire has a certain influence on the adhesive rubber patch 2, in the embodiment, in order to adapt to the pattern groove area on the tire tread, the adhesive layer 22 is made of soft material. Specifically, the soft material can be a high-elasticity polymer material with reversible deformation, and preferably, the Shore hardness of the adhesive layer 22 is less than or equal to 25 degrees. In this way, during the process of adhering the rubber patch 2 to the damaged area on the outer surface of the tire, due to the elasticity and plasticity of the adhesive layer 22 of the rubber patch 2, a part of the rubber patch 2 can be deformed and filled in the recessed area on the tire tread, so that the adhesive layer 22 has sufficient adhering area with the outer surface of the tire, thereby realizing sufficient adhesion to the damaged area of the tire.

[0033] Further, in order to make the rubber patch 2 adhere closely and reliably to the damaged area of the tire and be applicable to the repair of small puncture or damage, in the embodiment, the Brookfield viscosity of the adhesive layer 22 is 1800 cps to 4000 cps (centipoise·second). Specifically, the adhesive layer 22 can be in a "semi-solid" state and comprises an adhesive (such as rosin resin, synthetic resin). In this way, when there are foreign matters in the damaged area of the tire and it is inconvenient to clean, due to the high adhesive property of the adhesive layer 22, not only can the foreign matters be completely adhered and wrapped to prevent air leakage, but also the rubber patch 2 can be closely and firmly adhered to the outer surface of the tire.

[0034] According to the understanding of the inventor, the depth of the pattern groove of the passenger car tire is usually not more than 10 mm, and in consideration of ensuring the consistency of the repaired tire in appearance, preferably, the thickness of the rubber patch 2 is less than or equal to 10 mm.

[0035] Further, in order to ensure the air tightness of the repaired tire, in the embodiment, the adhesive patch 2 further comprises an air tight layer 23. The air tight layer 23 is located between the wear-resistant layer 21 and the adhesive layer 22, and specifically, can be glued between the wear-resistant layer 21 and the adhesive layer 22, which is beneficial to further prevent air leakage and ensure the stability of the tire pressure. Preferably, the air tight layer 23 is made of chlorinated butyl rubber or brominated butyl rubber with excellent air tightness.

[0036] Further, in order to improve the tensile shear strength of the adhesive patch 2, the air tight layer 23 has a grid line (not shown in the figure). Specifically, the grid line is formed by a plurality of fine lines intersecting with each other, and the grid line is arranged on the outer surface of the air tight layer 23 or embedded in the air tight layer 23, so as to disperse the load between the automobile tire and the ground and ensure the adhesion tightness of the adhesive patch 2 and the tire.

[0037] In the embodiment, the protective layer 1 is arranged opposite to the wear-resistant layer 21 relative to the adhesive layer 22. Specifically, the protective layer 1 comprises a PE film 11, and the bottom surface of the PE film 11 is attached to the outer surface of the adhesive layer 22, so as to reduce the loss of moisture in the adhesive layer 22 and ensure that the adhesion performance of the adhesive patch 2 meets the emergency use requirements within a certain period of time. It should be noted that the PE film 11 does not have adhesion performance, and the adhesion between the PE film 11 and the adhesive layer 22 is realized based on the adhesion performance of the adhesive layer 22, which is beneficial to reduce the adhesion force between the PE film 11 and the adhesive patch 2 and facilitate the user to tear off the adhesive patch 2 for use.

[0038] In the embodiment, when the tire repair is completed, in order to ensure the grip of the adhesive patch 2 adhered to the damaged part of the tire, the outer surface of the wear-resistant layer 21 can be provided with a knurled or toothed pattern (not shown in the figure), which forms a pattern similar to the tire pattern, so as to increase the friction between the adhesive patch 2 and the ground.

[0039] In some embodiments, the number of adhesive patches 2 on the protective layer 1 can be multiple, and in the embodiment, the number of adhesive patches 2 is nine, and the nine adhesive patches 2 are arranged in an array on the protective layer 1. It should be noted that the nine adhesive patches 2 have different size specifications, and the length, width and thickness thereof are not the same. It can be understood that in other embodiments, the adhesive patches 2 on the protective layer 1 can be arranged to have the same length and width and different thickness, or the same length and different width and thickness, or the same width and different length and thickness, etc., which is beneficial to the driver to select according to the size of the damaged part of the tire and the tire pattern.

[0040] The second aspect of the embodiment of the utility model discloses an automobile tool bag which comprises the emergency tire repair patch of the above-mentioned embodiment, so that the automobile tool bag has the characteristics of better practicability.

[0041] Further, as Figure 1As shown, the automobile tool package can further include a measuring tool 3. The measuring tool 3 is in the shape of a pin and is attached to the protective layer 1 by adhesive tape, and is used to measure the size of the damage on the outer surface of the tire, to assist the driver in selecting an appropriate emergency tire repair patch. Specifically, the measuring tool 3 includes a hand-held portion 31 and a measuring portion 32, wherein the measuring portion 32 is integrally formed with the hand-held portion 31, and a scale (not shown) is formed on the measuring portion 32. In this way, when the driver notices that the tire is damaged, the size of the damage and the corresponding pattern can be measured by the measuring tool 3 first, and then an appropriate patch 2 is selected, and the patch 2 is torn off from the protective layer 1 for emergency treatment. It should be noted that the measurement here refers to approximate measurement, which is convenient for the operator to estimate the approximate size of the patch 2 to be used, and to select an appropriate patch 2.

[0042] In order to facilitate understanding of the design concept of the present application, the following briefly describes the operation process:

[0043] During the driving of the automobile, after the driver finds the information reminding of the insufficient tire pressure, the automobile is first stopped and the double flash warning light is turned on, then the emergency triangular warning stand is placed, and then the position and size of the tire damage are checked and determined, and the tire damage is simply cleaned to ensure the adhesion of the patch 2. Then the emergency tire repair patch is taken out and the matching patch 2 is torn off from the protective layer 1, the adhesive layer 22 of the patch 2 is manually attached and adhered to the damage on the outer surface of the tire, and finally the emergency triangular warning stand is retracted and the driving continues to the nearest repair station. It should be noted that since there are various reasons for tire damage, when the tire is punctured by a sharp object such as a nail, glass or stone, and the sharp object is embedded in the tire, in order to ensure the safety of the operation, the driver only needs to simply clean the tire damage, then manually adhere the adhesive layer 22 of the patch 2 to the damage on the outer surface of the tire, and ensure that the adhesive layer 22 wraps the outer surface of the sharp object.

[0044] Compared with the prior art, the present application has the following beneficial effects:

[0045] The present application provides an adhesive layer 22 for adhering and filling the damage on the outer surface of the tire on the protective layer 1, and a wear-resistant layer 21 for contacting the ground on the adhesive layer 22. When the tire is punctured due to wear, aging or a sharp object, the driver can repair the tire in a short time, which is beneficial to improve the safety of personnel and vehicles during driving.

[0046] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
