Technical Field

[0001] This utility model relates to the field of backpack technology, and in particular to a folding backpack. Background Technology

[0002] A folding backpack is an innovative backpack design that effectively reduces the space it occupies when not in use through a special folding mechanism. This type of backpack is especially suitable for users who need to carry a backpack frequently, such as students, travelers, and business people. Its design not only takes into account portability but also the backpack's capacity and durability, ensuring that users have a good user experience in various environments.

[0003] In outdoor sports, when users are tired and need to sit down to rest, the bottom of a traditional backpack often comes into contact with the ground, leading to pollution and moisture problems. In certain situations, if the backpack can be used as a seat cushion, it will greatly improve the comfort of outdoor sports. Users can unfold the backpack seat cushion to avoid the backpack directly contacting the ground, thereby reducing the risk of pollution and moisture and bringing users an extra comfortable experience.

[0019] Reference Figure 1 - Figure 4As shown, this utility model provides a technical solution: a folding backpack, including a backpack body 1, a shoulder strap 2 fixedly connected to one side of the backpack body 1, an inflation device 3 installed at the bottom of the inner wall of the backpack body 1, an inflation head 4 installed at the bottom of the inflation device 3, an air cushion 5 fixedly connected to the bottom of the backpack body 1, the output end of the inflation head 4 placed inside the air cushion 5, and a support rod 6 fixedly connected to the bottom of the air cushion 5. By placing the inflation head 4 inside the air cushion 5, the worker can activate the inflation device 3 to inflate the air cushion 5 through the inflation head 4, causing the air cushion 5 to expand and form a... The rectangular seat cushion features an inflatable air cushion 5. When not in use, the air cushion 5 can be folded and stored without taking up much space. When the user uses the backpack outdoors, the air cushion 5 can be inflated and rotated forward to the user's buttocks. When the user sits down, the air cushion 5 is positioned between the user's buttocks and the ground. At the same time, the air cushion 5 provides support for the bottom of the backpack body 1, preventing the bottom of the backpack body 1 from directly contacting the ground and causing contamination. It also isolates the user from ground moisture, providing a comfortable sitting experience and preventing the user's clothing from being affected by ground moisture or stains.

[0020] Reference Figure 4 As shown in this embodiment: a sub-hook and loop fastener 7 is fixedly connected to the bottom of the backpack body 1, and a female hook and loop fastener 8 is fixedly connected to one side of the top of the air cushion 5. The surfaces of the sub-hook and loop fastener 7 and the female hook and loop fastener 8 are attached together. By setting the sub-hook and loop fastener 7 and the female hook and loop fastener 8, the staff can rotate the air cushion 5 forward, so that the sub-hook and loop fastener 7 on the top of the air cushion 5 are attached to the female hook and loop fastener 8, so that the air cushion 5 is fixed to the bottom of the backpack body 1 and forms a right angle with the backpack body 1, thereby placing it at the user's buttocks position so that the user can sit down at any time.

[0021] Reference Figure 1 , Figure 3 and Figure 4 As shown in this embodiment: both ends of the support rod 6 are rotatably connected to rubber plates 9, and holes 10 are opened on the surface of the rubber plates 9. Both sides of the backpack body 1 are fixedly connected to sleeve rods 11. When the staff rolls the air cushion 5 completely onto the surface of the support rod 6, the support rod 6 is located at the bottom of the backpack body 1. At this time, due to the stretchable design of the rubber material of the rubber plate 9, the rubber plate 9 is pulled so that the holes 10 are inserted into the surface of the sleeve rods 11, forming a pull on the support rod 6, fixing the support rod 6 to the bottom of the backpack body 1. This makes it easy for the staff to roll up and fix the air cushion 5, reducing the space occupied by the air cushion 5 when it is not in use.

[0022] Reference Figure 1 and Figure 2As shown in this embodiment: a limiting plate 12 is fixedly connected to one side of the rubber plate 9. The limiting plate 12 is placed on one side of the air cushion 5. The limiting plate 12 restricts the air cushion 5 on one side when it is rolled up on the surface of the support rod 6, preventing the air cushion 5 from sliding off the surface of the support rod 6 after it is rolled up and tightened, making the air cushion 5 more secure and stable after it is rolled up and fixed.

[0023] Reference Figure 1 , Figure 3 and Figure 4 As shown in this embodiment: a silicone pad 13 is fixedly connected to one side of the backpack body 1, and a thermal pad 14 is fixedly connected to the other side of the backpack body 1. The silicone pad 13 is placed at the bottom of the air cushion 5 and in contact with the ground. When the silicone pad 13 contacts the ground, the high friction and waterproof properties of the silicone pad 13 prevent the bottom of the air cushion 5 from sliding between the ground and the user when the user sits on top of the air cushion 5, causing discomfort or accidental slippage. The thermal pad 14 makes the air cushion 5 softer, more comfortable, and provides a certain degree of thermal insulation, making it less likely to get cold when used in cold weather.

[0024] Reference Figure 1 , Figure 3 and Figure 4 As shown in this embodiment: a zipper 15 is installed on the top of the backpack body 1. The zipper 15 is located on the surface of the upper half of the backpack body 1. The backpack body 1 has a central axis symmetrical structure. Through the upper and lower axis symmetrical design of the backpack body 1, and the zipper 15 being set on the outer side of the upper half of the backpack body 1, when the zipper 15 is opened, the top of the backpack body 1 can be folded down into the bottom of the inner wall of the backpack body 1, so that the inner side of the top of the backpack body 1 is tightly attached to the inner wall of the bottom of the backpack body 1, so that the top of the backpack body 1 is tucked into the bottom of the backpack body 1 to form a shoulder bag style, reducing the space occupied by the backpack body 1 by half, thus making it more convenient for users to carry and use.

[0025] Working Principle: The inflation head 4 is placed inside the air cushion 5, allowing the operator to activate the inflation device 3 to inflate the air cushion 5, forming a rectangular seat cushion. Because of its inflatable design, the air cushion 5 can be folded and stored away without taking up much space when not in use. When the user uses the backpack outdoors, the air cushion 5 can be inflated and rotated forward to face the user's hips. When the user sits down, the air cushion 5 is positioned between the user's hips and the ground. Simultaneously, the air cushion 5 provides support for the bottom of the backpack body 1, preventing direct contact between the bottom of the backpack body 1 and the ground, thus avoiding contamination and isolating it from ground moisture, providing the user with a comfortable environment. A comfortable sitting experience is provided, preventing users' clothing from being affected by wet or dirty ground. The design incorporates a male Velcro 7 and a female Velcro 8, allowing the operator to rotate the air cushion 5 forward. This causes the male Velcro 7 and female Velcro 8 to align, securing the air cushion 5 to the bottom of the backpack body 1 at a right angle, placing it at the user's hip position for easy sitting. When the operator rolls the air cushion 5 completely over the support rod 6, the support rod 6 is positioned at the bottom of the backpack body 1. The stretchable design of the rubber plate 9 allows for further manipulation, enabling the hole 10 to insert into the surface of the sleeve rod 11, forming a support... The support rod 6 is pulled to fix it to the bottom of the backpack body 1, making it easier for staff to roll up and fix the air cushion 5, reducing the space occupied by the air cushion 5 when not in use. The limiting plate 12 restricts the air cushion 5 on one side when it is rolled up on the surface of the support rod 6, preventing it from slipping off the surface of the support rod 6 after being rolled up and tightened, making the air cushion 5 more secure and stable after being rolled up. The silicone pad 13 is placed on the bottom of the air cushion 5 in contact with the ground. When the silicone pad 13 is in contact with the ground, the high friction and waterproof properties of the silicone pad 13 prevent the bottom of the air cushion 5 from sliding between the ground and the ground when the user sits on top of the air cushion 5. In case of user discomfort or accidental slip, the thermal pad 14 makes the air cushion 5 softer, more comfortable, and provides even insulation, preventing the user from getting cold in cold weather. The backpack body 1 features a symmetrical design with zippers 15 on the outer side of the upper part. When the zipper 15 is opened, the top of the backpack body 1 can be folded down into the bottom of the inner wall of the backpack body 1, making the inner side of the top of the backpack body 1 fit tightly against the inner wall of the bottom of the backpack body 1. This allows the top of the backpack body 1 to be tucked into the bottom of the backpack body 1, forming a shoulder bag style, reducing the space occupied by the backpack body 1 by half, thus making it more convenient for the user to carry and use.
