Technical Field

[0001] This utility model belongs to the technical field of wearable devices, and specifically discloses a half-body inflatable exoskeleton for the elderly that saves effort. Background Technology

[0002] The upper body of the human body is mainly supported by the legs. As people age, their physical functions gradually decline, resulting in slow and sluggish movements, weak leg strength, and difficulty in moving. Utility Model Content

[0003] This invention provides a half-body inflatable exoskeleton for the elderly, which provides auxiliary support for the upper body and reduces the stress on the legs, thereby improving the problem of mobility difficulties for the elderly.

[0004] The aforementioned pneumatic half-body exoskeleton for the elderly includes an airbag axillary support, titanium alloy support plates, a chest strap, and a waist belt. The two titanium alloy support plates are curved plates adapted to the human waist, with their top surfaces concave downwards to form cylindrical axillary support tubes. A flat support surface is provided inside the axillary support tube. The top surface of the airbag axillary support is a downward-concave arc surface, while the bottom surface, when not under pressure, is a downward-convex arc surface. Its sides conform to the inner wall of the axillary support tube. The airbag axillary support and the axillary support tube are inserted and fitted together, with the top surface outside the axillary support tube and the bottom surface inside. The top surface of the airbag armpit support is in flexible contact with the human body. When the air is compressed, it fills the armpit support cylinder, increasing the pressure area and reducing the pressure transmitted from the upper body weight to the waist belt. This is the principle behind saving effort. The chest belt is connected to two titanium alloy support plates, and the two ends are joined to form a chest fixation ring. The waist belt is located below the chest belt and is connected to the two titanium alloy support plates, and the two ends are joined to form a waist fixation ring. The chest fixation ring and waist fixation ring are used to fix the two titanium alloy support plates to both sides of the human body and are located between the armpit and the waist.

[0005] The aforementioned inflatable half-body exoskeleton for the elderly has four pressure levels for the airbag armpit support: 2.0 bar, 3.0 bar, 4.0 bar, and 5.0 bar, to suit people of different weights.

[0006] In the aforementioned inflatable half-body exoskeleton for the elderly, a lower fixing plate, a support spring, an upper adjusting plate, a positioning pin, and a positioning spring are installed inside the armpit support cylinder. Multiple positioning holes are sequentially arranged from top to bottom on the side wall of the armpit support cylinder. The lower fixing plate is fixed inside the armpit support cylinder and located below the positioning holes. The upper adjusting plate and the lower fixing plate are connected by a support spring. A pin hole is provided on the side wall of the upper adjusting plate, and the top surface of the upper adjusting plate serves as a support surface. The positioning pin slides into the pin hole via the positioning spring. The positioning pin is inserted into one of the multiple positioning holes via the positioning spring to fix the upper adjusting plate. This allows for adjustable position of the airbag armpit support, adapting to different body shapes and heights.

[0007] In the aforementioned half-body inflatable exoskeleton for the elderly, a spring positioning post is vertically installed on the top surface of the lower fixing plate; the support spring is sleeved outside the spring positioning post, and its top end is fixedly connected to the bottom surface of the upper adjusting plate.

[0008] In the aforementioned half-body inflatable exoskeleton for the elderly, each titanium alloy support plate includes an upper support plate, a tongue plate, and a lower support plate; the armpit support tube is set inside the upper support plate; two tongue plates are fixedly connected to the lower part of the upper support plate; the two tongue plates are inserted into the lower support plate, and the tongue plates are connected to the lower support plate by a pivot.

[0009] In the aforementioned half-body inflatable exoskeleton for the elderly, a chest strap loop is provided on the upper support plate, and a waist strap loop is provided on the lower support plate. The chest strap passes through the chest strap loop and is movably connected to the titanium alloy support plate to accommodate different human body shapes with different chest sizes. The waist strap passes through the waist strap loop and is movably connected to the titanium alloy support plate to accommodate different human body shapes with different waist sizes.

[0010] In the aforementioned inflatable half-body exoskeleton for the elderly, both the chest and waist belts are equipped with adjustable buckles to accommodate different body shapes with varying chest and waist sizes.

[0011] In the aforementioned inflatable half-body exoskeleton for the elderly, each titanium alloy support plate has a sponge pad on the side that fits against the human body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The aforementioned inflatable half-body exoskeleton for the elderly uses a chest strap and waist belt to secure two titanium alloy support plates to both sides of the body, positioned between the armpits and waist. The top surface of the airbag armpit supports the armpits, providing auxiliary support to the upper body under compression, reducing the burden on the legs. This can improve mobility issues for the elderly. It is also effortless to wear, lightweight, comfortable, and aesthetically pleasing. It is easy to manufacture, simple to wear, and harmless to the human body.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] This embodiment provides a labor-saving half-body inflatable exoskeleton for the elderly, including an airbag armpit support 1, a titanium alloy support plate 2, a chest strap 3, and a waist belt 4. The two titanium alloy support plates 2 are arc-shaped plates adapted to the human waist, with their top surfaces concave downwards to form cylindrical armpit support cylinders 2.1. A support surface, which is flat, is provided inside the armpit support cylinder 2.1. The top surface of the airbag armpit support 1 is a downward-concave arc surface, and the bottom surface, when not under pressure, is a downward-convex arc surface. The sides are flush with the inner surface of the armpit support cylinder 2.1. Wall adaptation; the airbag axillary support 1 is inserted and fitted with the axillary support tube 2.1, with the top surface located outside the axillary support tube 2.1 and the bottom surface located inside the axillary support tube 2.1 and supported by the support surface; the chest strap 3 is connected to two titanium alloy support plates 2, and the two ends are connected to form a chest fixation ring; the waist strap 4 is located below the chest strap 3 and is connected to the two titanium alloy support plates 2, and the two ends are connected to form a waist fixation ring; the chest fixation ring and the waist fixation ring are used to fix the two titanium alloy support plates 2 on both sides of the human body and are located between the armpit and the waist.

[0027] People vary in height, weight, and build. To suit most groups, the internal pressure of the airbag armpit support 1 is divided into four levels, as listed below.

[0028]

[0029] The aforementioned half-body inflatable exoskeleton for the elderly uses a chest strap 3 and a waist strap 4 to fix two titanium alloy support plates 2 to both sides of the body, located between the armpits and waist. The top surface of the airbag armpit support 1 supports the armpits and compresses under force to provide auxiliary support for the upper body, reducing the force on the legs and solving the problem of saving effort, as follows.

[0030] Basis 1: Based on Newton's laws of motion, the airbag armpit support 1 is an irregularly shaped airbag component. Its top surface is a downward-concave arc surface that matches the armpit, while the lower part is elliptical and slides within the armpit support cylinder 2.1. The internal pressure is divided into four levels, which can be selected according to individual body differences. The airbag armpit support 1 is similar to a pair of crutches supporting the armpit. When the gas in the airbag armpit support 1 is compressed, a strong internal energy is generated inside. This internal energy is constrained by the armpit support cylinder 2.1, generating an upward reaction force, thus functioning as a gas spring. This reaction force is opposite to the direction of the upper body's weight, achieving a force-saving effect.

[0031] The weight of the upper body minus 2 × the reaction force generated by the airbag armpit support 1 equals the force transmitted to the waist belt 4, which is the reason for saving effort. Reducing the weight-bearing load on the legs of the elderly can bring them great comfort.

[0032] Basis 2: According to Pascal's principle, when the airbag armpit support 1 is not under pressure, its bottom surface is a downward-convex arc surface, and there is a point contact between the bottom surface and the support surface inside the armpit support cylinder 2.1, with a gap between them. When pressure is applied, the airbag armpit support 1 expands, its long axis shortens, and its short axis lengthens, filling the armpit support cylinder 2.1. Because gas is compressible, the greater the weight, the greater its internal energy. The internal energy generates a strong upward reaction force, which is opposite to the direction of the upper body's gravity, thus achieving the effect of saving effort.

[0033] To accommodate differences in body height, the following solutions are provided:

[0034] In the aforementioned inflatable half-body exoskeleton for the elderly, the axillary support cylinder 2.1 contains a lower fixing plate 5, a support spring 6, an upper adjusting plate 7, a positioning pin 8, and a positioning spring 9. Multiple positioning holes are sequentially arranged on the side wall of the axillary support cylinder 2.1 from top to bottom. The lower fixing plate 5 is fixed inside the axillary support cylinder 2.1 and located below the positioning holes. The upper adjusting plate 7 and the lower fixing plate 5 are connected by the support spring 6. The side wall of the upper adjusting plate 7 has a pin hole, and the top surface of the upper adjusting plate 7 serves as a support surface. The positioning pin 8 is slidably inserted into the pin hole via the positioning spring 9. The positioning pin 8 is inserted into one of the multiple positioning holes via the positioning spring 9 to fix the upper adjusting plate 7. The length of the airbag axillary support 1 extending out of the axillary support cylinder 2.1 varies depending on the position of the upper adjusting plate 7, thus adapting to different heights.

[0035] In the aforementioned labor-saving half-body inflatable exoskeleton for the elderly, a spring positioning post 10 is vertically installed on the top surface of the lower fixing plate 5; a support spring 6 is sleeved on the spring positioning post 10, and its top end is fixedly connected to the bottom surface of the upper adjusting plate 7. The support spring 6 and the upper adjusting plate 7 are assembled first, and then the support spring 6 is sleeved on the spring positioning post 10 to achieve quick positioning and installation.

[0036] To accommodate the curvature of the human body, the following solutions are provided:

[0037] In the aforementioned pneumatic half-body exoskeleton for the elderly, each titanium alloy support plate 2 includes an upper support plate 2.2, a tongue plate 2.3, and a lower support plate 2.4; an armpit support tube 2.1 is disposed within the upper support plate 2.2; two tongue plates 2.3 are fixedly connected to the lower part of the upper support plate 2.2; the two tongue plates 2.3 are inserted into the lower support plate 2.4, and the tongue plates 2.3 and the lower support plate 2.4 are connected by a pivot 2.5. In this embodiment, the lower fixing plate 5 is connected to the upper support plate 2.2, and the tongue plates 2.3 are fixed below the lower fixing plate 5.

[0041] To address comfort concerns, the following solutions are offered:

[0042] In the aforementioned inflatable half-body exoskeleton for the elderly, each titanium alloy support plate 2 has a sponge pad 12 on the side that fits against the human body. The inflatable airbag armpit support 1 conforms well to the human body, the titanium alloy support plate 2 is made using a one-piece compression molding process, and the sponge pad 12 serves as a soft inner lining, making it very comfortable to wear.
