DETAILED DESCRIPTION

[0037] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1 to 10As shown, this embodiment proposes a hidden, carry-on modular airbag unit, comprising a back panel 1 and a shoulder strap 2 arranged on the back panel 1, characterized in that an airbag assembly is additionally provided, the airbag assembly comprising an annular airbag module 4, a shoulder strap airbag module 2-1, an interface assembly, a gas trigger module 5 and a plurality of airbag modules, the annular airbag module 4 being arranged on the back panel 1, the shoulder strap airbag module 2-1 being arranged in the shoulder strap 2, the plurality of airbag modules being connected to the circumference of the annular airbag module 4 and the shoulder strap airbag module 2-1 by means of the interface assembly, the annular airbag module 4 being communicated with the shoulder strap airbag module 2-1, the gas trigger module 5 being arranged on the back panel 1 and being communicated with the annular airbag module 4, and the gas trigger module 5 driving the airbag module to expand toward the direction of the human body after being triggered.

[0039] In this embodiment, a shoulder strap 2 is provided on the front end face of the back plate 1, and an airbag assembly is added to the back plate 1 and the shoulder strap 2. The airbag assembly includes an annular airbag module 4, a shoulder strap airbag module 2-1, an interface assembly, a gas trigger module 5 and several airbag modules. The annular airbag module 4 and the shoulder strap airbag module 2-1 are both airbag columns that can play a supporting and protective role, and the storage openings are hidden and stored in the outer lining of the back plate 1 and the outer lining of the shoulder strap 2 respectively by means of Velcro or hooks. The annular airbag module 4 is set on the front end face of the back plate 1 by hooks, sewing or zippers. A plurality of airbag modules are connected on the circumference of the annular airbag module 4 and the shoulder strap airbag module 2-1. At least one side of the plurality of airbag modules is connected and fixed to the corresponding position by hooks. The upper end of the annular airbag module has a shoulder strap airbag module 2-1 extending to the shoulder strap 2. 2-1 is arranged on the shoulder strap 2 by means of a snap fastener, sewing or zipper, and the connection point of the airbag module is connected to the connection point of the annular airbag module 4 and the connection point of the shoulder strap airbag module 2-1 by means of an interface component. The airbag module is folded and stored at the corresponding position, and the storage opening is hidden by a hidden button and Velcro. The gas trigger module 5 is arranged on the back plate 1 and is connected to the annular airbag module 4. When the gas trigger module 5 is accidentally triggered, gas is instantly filled into the annular airbag module 4. The gas enters each airbag module through the annular airbag module 4 and the shoulder strap airbag module 2-1, causing each airbag module to instantly expand, and the expansion direction is toward the human body, so that the airbag module can better fit the human body, thereby playing a comprehensive wrapping protection role, avoiding collision or scratches after the person carrying the load falls. The carrier can be a backpack, clothes or vest, etc.

[0040] In the prior art, airbags are often of an integral structure. When damage occurs somewhere, the entire structure often needs to be replaced. This is a cumbersome and costly process, and the airbag has a low reuse rate. In this embodiment, the inventors have specially designed a modular airbag structure. The annular airbag module 4 and the shoulder belt airbag module 2-1 are respectively connected to the safety airbag module by means of a detachable interface assembly. Several airbag modules are distributed along the circumference to provide all-round protection for the human body. When damage occurs somewhere in the airbag module, the airbag module can be easily removed and installed by removing the interface assembly, reducing unnecessary costs and facilitating operation. This ensures the integrity and timeliness of the protection after carrying the airbag unit. The airbag module can also be upgraded separately or a more comprehensive airbag assembly can be added later.

[0041] In the prior art, airbags are mostly in the form of integral airbag columns, but the gaps between the airbag columns are not protected. Sharp objects can easily enter the gaps or be scratched, resulting in a small protection area and insufficient protection. At the same time, the shape of the airbag column is not easy to fit the human body, and it only adds a buffer outside the human body. Existing airbag protective clothing is available in the form of clothes and vests. When purchasing, it is necessary to purchase airbag protective clothing of appropriate size according to the body shape. If the airbag protective clothing does not fit the body, the human body may sway in the airbag space. In this embodiment, the airbag modules designed by the inventor are reasonably distributed and have a large protection area. Foreign objects are not easy to enter between adjacent airbags, and the airbag modules can be attached to various carriers such as backpacks. When using a backpack, people will use the backpack shoulder straps and waist belt to adjust it to fit the body for a comfortable feeling. This further ensures the tightness between the airbag and the body, ensures that the airbag module fits the human body better after being inflated, and the human body will not sway in the space between the airbag modules, further improving the protection effect. Because the backpack's shoulder straps and waist belt are adjustable, users can reduce their worries about choosing the wrong size.

[0042] Furthermore, it also includes,

[0043] The interface assembly includes a fixing clip 6, a first flexible folding plate 7 and a second flexible folding plate 8. The fold line of the first flexible folding plate 7 is set at the interface end of the airbag module, and the interface end of the annular airbag module 4 and the interface end of the shoulder belt airbag module 2-1 are both connected to the fold line of the second flexible folding plate 8. The two ends of the first flexible folding plate 7 are folded along the fold line toward the side close to the airbag module, and the two ends of the second flexible folding plate 8 are folded toward the side away from the annular airbag module 4 and the shoulder belt airbag module 2-1. Line folding; the outer ends of the second flexible folding plate 8 are symmetrically swung inward and are provided with pressure plates 9, the pressure plate 9 and the second flexible folding plate 8 clamp the first flexible folding plate 7, the first flexible folding plate 7, the second flexible folding plate 8 and the pressure plate 9 are sealed and attached to the corresponding interfaces; the first flexible folding plate 7 and the second flexible folding plate 8 are provided with connected vents on the folding lines; after the two fixing clips 6 are buckled together, there is a circular channel 10 in the middle, and the vent is stretched and attached to the inner wall of the circular channel 10.

[0044] In this embodiment, the fold line of the first flexible folding plate 7 is set at the interface end of the airbag module, and the interface end of the annular airbag module 4 and the interface end of the shoulder belt airbag module 2-1 are both connected to the fold line of a second flexible folding plate 8. The two ends of the first flexible folding plate 7 are folded along the fold line toward the side close to the airbag module, and the fold line position is preferably the middle fold line. The two ends of the second flexible folding plate 8 are folded along the fold line toward the side away from the annular airbag module 4 and the shoulder belt airbag module 2-1. The setting positions of the two folding plates can be interchanged. The first flexible The folding plate 7 and the second flexible folding plate 8 are both U-shaped and can be folded. The first flexible folding plate 7 is placed between the second flexible folding plate 8 and the pressure plate 9. With the help of the three clamping and fixing, the pressure plate 9 and the second flexible folding plate 8 clamp the first flexible folding plate 7 together to realize the connection between the airbag module and the annular airbag module 4 and the shoulder belt airbag module 2-1 respectively. The fixing clips 6 are arranged in pairs. The fixing clips 6 are a two-half buckled structure. A pair of fixing clips 6 are connected to the position of the airbag module interface. The middle part after buckling forms a circle The first flexible folding plate 7, the second flexible folding plate 8 and the pressing plate 9 are all sealed and attached to the corresponding interfaces. The sealing connection method is preferably a sealing gasket, an adhesive seal, a welding seal, a gluing seal, a magnetic seal or a clamping sealing component. The first flexible folding plate 7 and the second flexible folding plate 8 are both provided with a connected vent on the fold line. After the vent is opened, it is attached to the inner wall of the circular channel 10. The vent connects the two airbag modules to realize the circulation of gas. When installing, only the first The flexible flap 7 is placed between the second flexible flap 8 and the pressure plate 9, and then the pressure plate 9 presses the first flexible flap 7 onto the second flexible flap 8. The first flexible flap 7, the second flexible flap 8 and the pressure plate 9 are squeezed against each other to complete the connection. When disassembling, the sealed connection is cancelled, and then the first flexible flap 7 is removed from between the pressure plate 9 and the second flexible flap 8. This makes the installation and disassembly of the airbag module very convenient. When a local airbag module is damaged, only the local airbag module needs to be replaced.

[0045] The fixing clip 6 is laterally provided with a slot. When the airbag module is not expanded, it is in a sheet shape. The first flexible folding plate 7, the second flexible folding plate 8 and the pressure plate 9 form a connecting unit. When the fixing clip 6 is used, the slot is used to accommodate the edges of the connecting unit and the airbag module. The edges of the connecting unit and the airbag module on both sides are inserted into the slot. The bottom of the slot is a U-shaped constriction. The fixing clip 6 wraps the connecting unit. The outer edge of the connecting unit enters the U-shaped constriction. The U-shaped constriction plays a gathering and limiting role, making the connecting unit fit more tightly.

[0046] The shape of the vent after being expanded is preferably circular to ensure smooth gas flow in the inflation channel. In this embodiment, the inventor's design of the circular channel 10 is more in line with the expansion trend direction at the interface, so that the flexible folding plate fits the inner wall of the circular channel 10 more closely and ensures good sealing.

There is a chest strap between the two shoulder straps 2. After the chest airbag module 12 is expanded, it will be controlled between the chest strap and the human chest, so that it fits the human body more closely. A first pull rope 13 is connected between the outer end of the shoulder airbag module 11 and the outer end of the chest airbag module 12 in a snap-fit ​​manner. When the two airbag modules are expanded at the same time, the chest airbag module 12 is expanded toward the human body, and the outer end of the shoulder airbag module 11 is pulled inward by means of the first pull rope 13, so that the shoulder airbag module 11 moves toward the human body, thereby fitting the shoulder, preventing the shoulder airbag module 11 from floating, and ensuring the protective effect.
