Description

An airbag-type backpack back panel Technical Field

[0001] This utility model relates to the technical field of backpack carrying systems, specifically to an airbag-type backpack back panel. Background Technology

[0002] The core of the intermittent dynamic carrying system theory lies in intermittent dynamic pressure, where at least two sets of skin alternately bear pressure, ensuring that at least one set of skin is never under pressure. Intermittent dynamic pressure serves as the underlying logic for alleviating fatigue, heat, and other problems caused by continuous static pressure. This intermittent dynamic pressure can be traced back to a medical treatment method—intermittent pneumatic compression. The principle of intermittent pneumatic compression is that local pressure causes temporary ischemia; as the pressure dissipates, blood flow is rapidly restored due to the heart's pumping action, thus promoting blood circulation. In the medical field, this is a relatively mature physical rehabilitation method. For example, the rapid relief of ischemic rest pain after applying foot pulse compression devices, and the positive effect of continuous intermittent pneumatic pressure on the feet and calves of limping patients on the average systolic blood flow of the popliteal artery. Applying this to backpacks can promote blood circulation in the pressure-bearing areas of the body.

[0003] Unlike pneumatic boots used in rehabilitation, which apply pressure to specific areas of the body, a carrying system is essentially a pressure transfer device. A well-designed carrying system distributes pressure evenly across the body, both bearing the weight of the backpack and providing support between the backpack and the body. Therefore, an intermittent dynamic carrying system is essentially a dynamically alternating pressure transfer system and does not create pressure on the body itself.

[0004] Furthermore, because a proper distribution of force and a backpack positioned slightly away from the body enhance ventilation, this invention proposes a carrying system with an airbag-type back panel that balances ventilation with the other two points:

[0005] Firstly, it transforms the static pressure of a backpack into dynamic pressure. The principle of dynamic pressure is similar to that of massage, which is a positive pressure feedback that helps improve comfort.

[0006] Secondly, dynamic fit. Summary of the Invention

[0007] This invention proposes an airbag-type backpack back panel, which solves the problems in related technologies where prolonged backpack carrying accelerates muscle fatigue due to pressure on muscles and blood vessels, and causes discomfort due to poor ventilation, increased humidity and temperature in the contact area.

[0009] Backpack;

[0010] A shoulder strap assembly that is fastened to a backpack, the shoulder strap assembly including a scapular pad on which two shoulder straps are provided;

[0011] Back panel attached to the backpack;

[0015] Shoulder pads glued to the shoulder straps;

[0016] Back pads are bonded to the scapular padding board;

[0017] The bottom lumbar support pad and side lumbar support pad are bonded to the waist belt;

[0018] Air pump set;

[0019] The shoulder pads, back pads, bottom support lumbar pads, and side lumbar pads are all equipped with airbags inside. Each airbag is connected to an air pump assembly via an air tube. The air pump assembly is electrically connected to a control processor, an electromyography sensor, and an external power supply.

[0020] Preferably, the airbag component is provided with airbag cavities distributed in a mesh pattern.

[0021] Preferably, the airbag component includes a first airbag and a second airbag, wherein the first airbag and the second airbag are provided with a plurality of airbag cavities arranged in an alternating manner, the airbag cavities on the first airbag are connected to each other, the airbag cavities on the second airbag are connected to each other, and the sizes of the first airbag and the second airbag are compatible.

[0025] Preferably, each shoulder strap has a plug at its end, and the backpack has a buckle.

[0026] The beneficial effects of this utility model are as follows:

[0027] In this utility model, the detachable design of the backpack, combined with the modular design of the dynamic support mechanism, allows users to adjust the position of the air cushions at the shoulder, back, and waist pressure points according to their body shape, thus adapting to users of different body types. Furthermore, the air cushions can be flexibly removed and added, making it highly practical.

[0028] In this invention, electromyography (EMG) sensors collect and detect EMG signals in the heavy-load area to identify muscle fatigue. This activates the dynamic support mechanism, controlling the grid-designed airbags on the airbag components for dynamic support. The airbags in different areas of the airbag components are alternately inflated and deflated, causing the airbag components to deform and adjust their contact position with the skin. This causes the shoulder pads, back pads, bottom lumbar pads, and side lumbar pads to deform, thereby adjusting their contact position with the body and creating ventilation channels. Dynamic compression is applied to the stress points when the body is being carried, improving the comfort of the back stress points and ensuring dynamic fit of the parts in contact with the body.

[0043] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0044] Example

[0045] As shown in Figures 1 to 5, this embodiment proposes an airbag-type backpack back panel, including a detachable backpack. The backpack comprises: a shoulder bag 1, designed to be wider at the top and narrower at the bottom from the front, and angled inwards from the sides to centralize the center of gravity; shoulder strap components 2 fastened to the shoulder bag 1, the shoulder strap components 2 including a scapula pad 22, with two shoulder straps 21 on the scapula pad 22, each with a plug 25 at its end; and buckles 26 on the shoulder bag 1. The fastening design allows for easy disassembly and reassembly, and the height can be adjusted to fit the user's body shape. The back panel 3 fastened to the shoulder bag 1 features a ventilated design and an arched design that conforms to the structure of the human back. The height of the back panel 3, which is fastened to the back bag 1, adapts to the curves of the user's back and waist, improving fit. The waist belt 4, which is installed on the back panel 3, is fixed to the back panel 3 by connecting ribs 41, enhancing the stability of the connection between the waist belt 4 and the back panel 3. Both the shoulder strap component 2 and the waist belt 4 are provided with an adhesive layer 6 and an intermittent airbag dynamic support structure 5. The intermittent airbag dynamic support structure 5 is modularly set and pasted on the adhesive layer 6. The intermittent airbag dynamic support structure 5 is used to dynamically adjust the deformation of the airbags in the stress-bearing parts of the shoulder strap component 2 and the waist belt 4, providing dynamic support in the contact parts with the body, effectively relieving muscle fatigue caused by long-term carrying and improving carrying comfort. The intermittent airbag dynamic support structure 5 includes: a shoulder pad 51 bonded to the shoulder strap 21; a back pad 52 bonded to the scapular pad 22; a bottom support lumbar pad 53 and a side lumbar pad 54 bonded to the waist belt 4; and an air pump assembly 55. Each of the shoulder pad 51, back pad 52, bottom support lumbar pad 53, and side lumbar pad 54 is equipped with an airbag component 8. Each airbag component 8 is connected to the air pump assembly 55 through an air tube 56. The air pump assembly 55 is electrically connected to a control processor 7, an electromyography sensor 71, and an external power source. This transforms the negative pressure from the backpack into dynamic positive pressure, promotes blood flow, relieves fatigue, and establishes a ventilation channel to reduce temperature and humidity at the pressure point.

[0046] The airbag component 8 is provided with airbag cavities distributed in a mesh pattern. To ensure the stability of the carrying strap and the simplicity of the structure, an alternating mesh pattern is adopted. The airbag component 8 deforms alternately to promote airflow in the carrying system. The airbag component 8 includes a first airbag 81 and a second airbag 82. The first airbag 81 and the second airbag 82 are provided with several airbag cavities arranged in an alternating pattern. The airbag cavities on the first airbag 81 are interconnected, and the airbag cavities on the second airbag 82 are interconnected. The sizes of the first airbag 81 and the second airbag 82 are matched. The first airbag 81 and the second airbag 82 inflate and deflate intermittently to optimize pressure and promote active airflow in the gaps. The pressure area is divided into two groups of stress points. Each group of stress points is inflated in turn to provide support. The inflated group corresponds to skin pressure, and blood flow is temporarily obstructed. The uninflated group does not have skin pressure, and blood flow is normal.

[0047] The backpack 1 is provided with a fastening panel 11, which has a multi-layered, downward-facing hanging opening. The scapula pad 22 is provided with an inner fastening panel 23, which has a multi-layered, upward-facing hanging opening. The top of the back panel 3 is fastened to the hanging opening by a hanging buckle 31, and the inner fastening panel 23 is fastened to the hanging opening by an S-shaped buckle 24. The fastening height between the scapula pad 22 and the fastening panel 11 can be flexibly adjusted. By adaptively adjusting the height of the shoulder strap 21 according to the user's body shape, the shoulder strap 21 can fit the user's body more closely. It can also be adjusted in conjunction with the shoulder pad 51 to ensure that the shoulder pad 51 completely covers the user's shoulders and chest underarms, thereby improving carrying comfort.

[0048] The two sides of the bottom end of the back panel 3 extend outward, and the back bag 1 is provided with a foot sleeve 32. The two sides of the bottom end of the back panel 3 are inserted into the foot sleeve 32, so that the back panel 3 forms a triangular support for the back bag 1, increasing the stability of the structure.

[0049] In this embodiment, a modular design is adopted: combined with the shape of the human body's pressure area, it is integrated with the back panel 3. At the same time, taking into account the different shoulder widths of different people, the back pad 52, shoulder pad 51, side lumbar pad 54 and bottom lumbar pad 53 are modularly attached to the shoulder strap 21 and waist belt 4, which allows users to adjust the fixed position of the back pad 52 at the shoulder blade, the fixed position of the side lumbar pad 54 and bottom lumbar pad 53 at the waist, and the fixed position of the shoulder pad 51 at the shoulder and under the armpit according to their own size.

[0050] To ensure the intermittent airbags meet ergonomic requirements and achieve optimal body compliance, special consideration was given to the arrangement of blood vessels and muscle direction in the shoulder area. All airbag components 8 are designed with a mesh pattern, enabling dynamic support. The original shoulder stress area is divided into two groups: shoulder pads 51 and back pads 52, with the two groups alternating in pressure. Similarly, the lumbar region, which is in contact with the body, is divided into two groups: a bottom lumbar pad 53 and a side lumbar pad 54, providing alternating support in a continuous cycle. This concentrates the original pressure on one group, leaving the other group unaffected, ensuring consistent protection. One group of body areas does not contact the backpack, so the blood flow to the uncompressed group is unobstructed, while there is enough space for ventilation and heat dissipation. According to the above pressure zone division method, the pressure group bears all the load, and the pressure is twice the original pressure. However, the underlying logic of this support system is alternating support, which is in line with the effective way to promote blood flow in the field of hemodynamics - intermittent pneumatic compression (IPC). The principle of IPC is that applying pressure to muscles intermittently can significantly promote blood flow velocity. This principle is used to enhance the blood flow velocity in pressure areas such as the shoulders, accelerate local muscle metabolism, and relieve fatigue.

[0051] A dynamic support system is achieved through the combination of airbags and a control system (the control system being an existing combination of smart hardware). Airbags, as an inflatable material, possess advantages such as being lightweight, easily moldable, and having no foreign body sensation. Using airbags as unit supports offers significant advantages. With the assistance of smart hardware, theoretically, it is possible to achieve an adaptive dynamic support state automatically without subjective control. From the perspective of the backpack itself, the size of the airbags is easily molded, making them ideal for modular design. They are also low-cost. Considering the school environment for junior high school students, as well as future maintenance and cleaning, airbags are the optimal solution.

[0052] As shown in Figure 7, the control system of the intermittent airbag dynamic support structure 5 is as follows: First, the electromyography sensor 71 receives the body's state in the pressure area—physiological dimensions, pressure state, fatigue state, and thermal comfort; second, the control processor 7 processes the received information, such as adjusting the opening state of the intermittent airbag dynamic support structure 5; third, the control air pump group 55 performs various functions to achieve reasonable force transmission, fit, ventilation, and stability; fourth, the electromyography sensor 71 collects information again for a new round of judgment; through the pre-set program of the intelligent hardware, it autonomously collects, judges, executes, and outputs information, reducing or eliminating the need for the user's attention to achieve the expected purpose.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
