Description

Technical Field

[0001] The present application relates to the field of household articles, and in particular to an airbag with internal support. Background Art

[0002] An air mattress is a highly flexible and elastic mattress that expands in volume when inflated. Advantages: An air mattress's elasticity doesn't easily deform, making it very comfortable to sleep on, like a spring bed, and easy to carry around. The pillar-shaped air mattress, resembling a honeycomb, consists of several small airbags that increase air flow across the surface, making it highly breathable.

[0003] The pillar-type airbags currently in use are completely supported internally by inflation. In actual use, if a single pillar airbag leaks, that part will sink significantly, reducing the customer experience. In addition, there is no other supporting structure inside, which causes the other airbags next to the pillar airbag to be subjected to greater force, which may further cause overall leakage and affect the overall service life. Utility Model Content

[0007] By adopting the above technical solution, when the top airbag and the lower airbag are inflated, their lower surfaces will gradually press the first protection block and the second protection block inside the main airbag downward and upward synchronously. At this time, the support spring contracts and only supports the top airbag and the lower airbag. When damage occurs in the top airbag and the lower airbag, the internal gas escapes. At this time, the force of the support spring can push the first protection block and the second protection block to move, replacing the top airbag and the lower airbag for support.

[0008] Preferably, a connecting airbag is provided on the side of the main airbag, a connecting groove is provided inside the connecting airbag, and the top airbag and the lower airbag are connected via the connecting airbag.

[0009] By adopting the above technical solution, the second buckling part and the interior of the lower airbag are inflated through the inflation port, and the gas gradually enters the second buckling part and the interior of the lower airbag. At this time, some of the gas will enter the first buckling part through the connecting groove in the connecting airbag.

[0010] Preferably, a first buckling portion is circumferentially provided on the lower side surface of the top airbag, and a second buckling portion is circumferentially provided on the upper side surface of the lower airbag.

[0011] By adopting the above technical solution, the upper and lower parts of the main airbag are located inside the first buckling part and the second buckling part, and the first buckling part and the second buckling part are buckled to the upper and lower ends of the main airbag respectively, which is convenient for connection with the main airbag.

[0012] Preferably, there are multiple communicating airbags, which are respectively located on the side of the main airbag in a uniform circumferential portion, and the multiple communicating grooves inside the communicating airbags are respectively connected to the inside of the first buckling part and the second buckling part.

[0015] By adopting the above technical solution, the first buckling portion and the second buckling portion are buckled to the upper and lower ends of the main airbag respectively, which is convenient for connection with the main airbag.

[0016] Preferably, an inflation port is provided on the outer side of the second buckling portion.

[0017] By adopting the above technical solution, the second buckling portion and the interior of the lower airbag are inflated through the inflation port, and the gas gradually enters the second buckling portion and the interior of the lower airbag.

[0018] Preferably, the first protection block and the second protection block are made of rubber, and both ends of the support spring are respectively connected to the inside of the first protection block and the second protection block.

[0019] By adopting the above technical solution, when the lower airbag and the top airbag are deflated, weight is applied to the main airbag and the support spring, and the first protective block and the second protective block can ensure that the support spring will not puncture the main airbag.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application inflates the top and bottom airbags, causing their lower surfaces to gradually and synchronously press the first and second protective blocks inside the main airbag downward and upward. At this time, the support springs contract, leaving only the top and bottom airbags for support. When damage occurs in the top and bottom airbags, the gas inside escapes, and the force of the support springs pushes the first and second protective blocks to move, replacing the top and bottom airbags in providing support. This prevents excessive force on other parts, which could cause overall damage.

[0022] 2. The present application inflates the interior of the second buckling part and the lower airbag through the inflation port, and the gas gradually enters the interior of the second buckling part and the lower airbag. At this time, some of the gas will enter the first buckling part through the connecting groove in the connecting airbag, and the gas will gradually fill the first buckling part and the interior of the top airbag, so that the whole can be inflated conveniently.
