[0016] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, an airbag structure for emergency escape and rescue includes an airbag body 1 formed by connecting multiple airbag materials. The rear end face of the airbag body 1 is provided with at least one first folding groove 11. When the airbag body 1 is inflated, its cross-section is a triangular or trapezoidal structure. When the airbag body 1 is in the stored state, the rear end of the airbag body 1 folds inward along the first folding groove 11. This facilitates the folding of the entire airbag body 1, reduces the volume of the folded airbag, and makes the airbag easier to carry and use. like Figure 3 As shown, at least one second folding groove 12 is provided on each of the opposite sides of the airbag body 1. When the airbag body 1 is in the stored state, both sides of the airbag body 1 fold inward along their respective second folding grooves 12, facilitating the unfolding and folding of the airbag body 1 and making it easy to use. The airbag body 1 is made of nylon + TPU composite material, PA + PE composite material, or PVC material, ensuring that the airbag body 1 has sufficient strength and preventing easy damage. The joints of multiple airbag materials are heat-pressed and sealed, and each seal is provided with stitching to ensure that the airbag as a whole has good sealing performance and stability. The airbag body 1 has anti-slip pads 13 on both the top and bottom surfaces. The top surface of the airbag body 1 is used to contact the side of a motorcycle or the bottom of a car that needs to be rescued and freed, while the bottom surface of the airbag body 1 is in contact with the ground. The surface of the anti-slip pads 13 is sprayed with multiple anti-slip patterns in the horizontal or vertical direction. The multiple anti-slip patterns are arranged at equal intervals and are made of polyurea material. This structure facilitates greater contact friction between the airbag body 1 and the ground and the supported object, ensuring that the airbag can stably support the object after inflation. In this way, when the airbag body 1 is inflated, the rear end and the left and right sides are fully extended, and its top surface is tilted at a certain angle, which can form a tilting support for the tilted motorcycle, so that the user can quickly right the motorcycle or get it out of trouble.

[0018] like Figure 1 , Figure 2 and Figure 4 As shown, the airbag body 1 has a hole, and a base 14 is provided at the hole. A valve core assembly 01 is fixedly installed on the base 14. The valve core assembly 01 is used to connect to an adapter air pump for inflation, facilitating the inflation and deflation of the airbag body 1 and greatly simplifying its use. The base 14 and the valve core assembly 01 can be located on the side or the top surface, etc., depending on the specific application.

[0019] like Figure 4 As shown, the base 14 is provided with a connecting post 15, the bottom side of the connecting post 15 is provided with multiple limit buckles 16, and the inner side of the connecting post 15 is provided with a threaded hole 17, and the top edge of the threaded hole 17 is provided with a pressure plate 18; the connecting post 15 facilitates the installation of the valve core assembly 01, facilitates the stable connection between the valve core assembly 01 and the connecting post 15, and also facilitates flexible disassembly and assembly according to usage requirements.

[0021] like Figure 3 and Figure 8 As shown, an airbag structure for emergency escape and rescue includes an airbag body 1 formed by connecting multiple airbag materials. The front and rear faces of the airbag body 1 are provided with at least one first folding groove 11. When the airbag body 1 is inflated, it is a rectangular or polygonal structure. When the airbag body 1 is in a collapsed state, the rear end of the airbag body 1 folds inward along the first folding groove 11. This facilitates the folding of the entire airbag body 1, reduces the volume of the folded airbag, and makes it easier to carry and use the airbag. like Figure 3 As shown, at least one second folding groove 12 is provided on each of the opposite sides of the airbag body 1. When the airbag body 1 is in the stored state, both sides of the airbag body 1 fold inward along their respective second folding grooves 12, facilitating the unfolding and folding of the airbag body 1 and making it easy to use. The airbag body 1 is made of nylon + TPU composite material, PA + PE composite material, or PVC material, ensuring that the airbag body 1 has sufficient strength and preventing easy damage. The joints of multiple airbag materials are heat-pressed and sealed, and each seal is provided with stitching to ensure that the airbag as a whole has good sealing performance and stability. The airbag body 1 has anti-slip pads 13 on both the top and bottom surfaces. The top surface of the airbag body 1 is used to contact the side of a motorcycle or the bottom of a car that needs to be rescued and freed, while the bottom surface of the airbag body 1 is in contact with the ground. The surface of the anti-slip pads 13 is sprayed with multiple anti-slip patterns in the horizontal or vertical direction. The multiple anti-slip patterns are arranged at equal intervals and are made of polyurea material. This structure facilitates greater contact friction between the airbag body 1 and the ground and the supported object, ensuring that the airbag can stably support the object after inflation. like Figure 1 , Figure 2and Figure 4 As shown, the airbag body 1 has a hole, and a base 14 is provided at the hole. A valve core assembly 01 is fixedly installed on the base 14. The valve core assembly 01 is used to connect to the adapter air pump for inflation, which facilitates the inflation and deflation of the airbag body 1 and greatly facilitates the use of the airbag body 1.

[0022] like Figure 4 As shown, the base 14 is provided with a connecting post 15, the bottom side of the connecting post 15 is provided with multiple limit buckles 16, and the inner side of the connecting post 15 is provided with a threaded hole 17, and the top edge of the threaded hole 17 is provided with a pressure plate 18; the connecting post 15 facilitates the installation of the valve core assembly 01, facilitates the stable connection between the valve core assembly 01 and the connecting post 15, and also facilitates flexible disassembly and assembly according to usage requirements.

[0023] In this way, when the airbag body 1 is inflated, the front end, rear end and left and right sides are fully expanded, forming a rectangular structure, which can provide support for the car, so that users or rescuers can repair tires or perform emergency rescue operations.

[0024] Example 3

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, an airbag structure for emergency escape and rescue includes an airbag body 1. The rear end face of the airbag body 1 is provided with at least one first folding groove 11. When the airbag body 1 is inflated, its cross-section is a triangular or trapezoidal structure. When the airbag body 1 is in the stored state, the rear end of the airbag body 1 folds inward along the first folding groove 11. This facilitates the folding of the entire airbag body 1, reduces the volume of the folded airbag, and makes it easier to carry and use the airbag.

[0026] like Figure 3 As shown, at least one second folding groove 12 is provided on each of the opposite sides of the airbag body 1. When the airbag body 1 is in the stored state, the two sides of the airbag body 1 fold inward along their respective second folding grooves 12, which facilitates the unfolding and folding of the airbag body 1 and makes it easy to use. The airbag body 1 is made of nylon + TPU composite material, PA + PE composite material, or PVC material to ensure that the airbag body 1 has sufficient strength and avoids easy damage. In addition, the joints are heat-pressed and sealed to ensure that the airbag as a whole has good sealing performance. The top and bottom surfaces of the airbag body 1 are provided with anti-slip pads 13. The surface of the anti-slip pads 13 is sprayed with multiple anti-slip patterns horizontally or vertically. The multiple anti-slip patterns are arranged at equal intervals and are made of polyurea material. This structure facilitates greater contact friction between the airbag body 1 and the ground and the supported object, ensuring that the airbag can stably support the object after inflation.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the airbag body 1 has a hole, and a base 14 is provided at the hole. A valve core assembly 01 is fixedly installed on the base 14. The valve core assembly 01 is used to connect to the adapter air pump for inflation, which facilitates the inflation and deflation of the airbag body 1 and greatly facilitates the use of the airbag body 1.

[0028] like Figure 4 As shown, the base 14 is provided with a connecting post 15, the bottom side of the connecting post 15 is provided with multiple limit buckles 16, and the inner side of the connecting post 15 is provided with a threaded hole 17, and the top edge of the threaded hole 17 is provided with a pressure plate 18; the connecting post 15 facilitates the installation of the valve core assembly 01, facilitates the stable connection between the valve core assembly 01 and the connecting post 15, and also facilitates flexible disassembly and assembly according to usage requirements.

[0029] like Figure 1 As shown, the valve core assembly 01 includes a valve body 2, a sealing cap 4, and a connecting band 3. The valve body 2 is threadedly connected to the threaded hole 17. The connecting band 3 is sleeved on the connecting post 15, and the sealing cap 4 is threadedly connected to the connecting post 15. The sealing cap 4 is pressed tightly onto the connecting band 3. The valve body 2 facilitates the restriction of the gas expulsion inside the airbag, which ensures that the airbag remains in an inflated state after being inflated. It also facilitates the expulsion of the gas in the airbag using the valve body 2 after use. The cooperation between the connecting band 3 and the sealing cap 4 facilitates the sealing of the opening at the top of the connecting post 15, thereby ensuring the stability of the air inlet and outlet of the airbag body 1.

[0030] like Figure 5 As shown, the valve body 2 is provided with a threaded connection part 21, which facilitates connection with the threaded hole 17. A pressure plate 22 is provided above the threaded connection part 21 on the valve body 2. A sealing gasket is provided at the bottom of the pressure plate 22. The pressure plate 22, in conjunction with the sealing gasket, is easily pressed onto the pressure table 18, thereby achieving a seal between the valve body 2 and the valve core. A hexagonal body 24 is provided in the center of the top surface of the pressure plate 22, which facilitates the assembly and disassembly of the valve body 2, thus simplifying its use. A pressing rod 25 is provided in the center of the valve body 2. The top of the pressing rod 25 protrudes from the pressure plate 22, allowing for easy pressing during venting to expel gas from the airbag body 1. Furthermore, the top of the pressure plate 22 is provided with an air hole 23 communicating with the interior of the valve body 2. The air hole 23 facilitates the flow of gas into or out of the airbag body 1; pressing the pressing rod 25 during venting allows gas to be expelled through the air hole 23.

[0031] like Figure 6As shown, the connecting strip 3 is provided with a sleeve plate 31, and the sleeve plate 31 has a sleeve hole 32 in the middle. The sleeve hole 32 is fitted onto the connecting post 15, thereby facilitating the installation of the connecting strip 3. The limiting buckle 16 is used to limit the connecting strip 3 and ensure the stability of the connecting strip 3 on the connecting post 15. The sleeve plate 31 is provided with a handle 33 on its side; the handle 33 is used to pull the connecting strip 3. The end of the connecting strip 3 near the end without the handle 33 is provided with a sealing head 34, and the sealing head 34 is provided with a sealing plug 35. The sealing head 34 and the sealing plug 35 are used to facilitate sealing the cap.

[0032] like Figure 7 As shown, the top of the sealing cover 4 is provided with a sealing ring 41, and both the sealing cover 4 and the sealing ring 41 are provided with an insertion hole 42 in the middle. The sealing head 34 and the sealing plug 35 can seal the insertion hole 42, which makes it convenient for the top of the sealing cover 4 to open and close, thereby facilitating the inflation and deflation of the airbag.

[0033] Example 4

[0034] like Figures 1-8 As shown, an airbag body includes the aforementioned airbag structure for emergency escape and rescue.

[0035] Working principle: In the storage state, the airbag body 1 can be folded inward along the first folding groove 11 at the rear end and the second folding grooves 12 on the opposite sides, greatly reducing the volume for easy carrying; in use, first pull the connecting strap 3 by the handle 33 on the connecting strap 3, remove the plug 35 at the sealing head 34, open the insertion hole 42 in the middle of the sealing cover 4 and the sealing ring 41, and then connect the adapter air pump to the valve body 2 of the valve core assembly 01. The air pump inflates the airbag body 1 through the air hole 23 on the valve body 2. After inflation, the airbag body 1 has a triangular or trapezoidal cross-section, and the anti-slip pad 13 on its bottom surface (which can increase the friction with the ground) The contact friction with the supported object ensures stable support for the object. At the same time, the valve body 2 can restrict the internal gas from escaping to maintain the airbag's inflated state. After use, press the pressing rod 25 of the pressure plate 22 protruding from the top of the valve body 2, and the gas in the airbag will be discharged from the air hole 23. After venting, the airbag body 1 is folded inward along the first and second folding grooves 12 to restore the storage state. Throughout the process, the material of the airbag body 1 ensures strength, the heat-pressed sealing of each connection and the sealing ring 41 of the sealing cover 4 ensure airtightness, and the limit buckle 16 on the connecting column 15 can fix the connecting strap 3 to ensure stability during inflation, deflation, storage and use.

[0036] In summary, compared with the prior art, this application provides a first folding groove 11 at the rear end of the airbag body 1 and second folding grooves 12 on both sides of the airbag body 1. This structure facilitates the folding of the airbag body 1 when not in use.
