Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to an airbag driving component. Background Art

[0002] The physical functions of the elderly decline with age, among which the decline of walking function is a problem faced by most elderly people. Walking, as a complex behavioral system, requires the coordination of nerves, bones and muscles, and comprehensive regulation of speed, frequency, height, step length, stride, direction and posture, and completes a series of walking cycles through the coordination between two multi-segment lower limbs and the whole body. The impact of aging on human bones, muscles, nerves, etc. is manifested in: decreased bone density, more fragile bones and easy to break; degenerative changes such as atrophy of muscle fibers; decreased reaction speed and cognitive ability. Physiological aging and pathological changes lead to changes in the gait of the elderly, with gait deformation phenomena such as leaning forward, slow and low foot lifting, dragging on the ground, arcing, foot inversion, swaying, etc., accompanied by looking down and stopping. The degeneration of walking function reduces the ability of the elderly to live independently and the quality of life, making them more prone to accidents such as gait deformation and instability and falling, and may also cause psychological problems such as loss and inferiority.

[0003] Lower limb power-assisted exoskeletons are an external device that solves the above problems. However, traditional rigid lower limb power-assisted exoskeletons have some inevitable disadvantages: (1) Poor comfort. The rotation axes of the human body and the exoskeleton in the sagittal plane (i.e., the symmetry plane of the human body) must be aligned. If they are not completely aligned, the rigid connecting rods connected by the joints will hinder the movement of the biological joints, which may cause the user to fall or get injured. In addition, due to differences in user physiological size, force habits, etc., rigid exoskeletons must use additional sensors and mechanism designs to achieve compatibility with different groups of people; (2) Poor portability. Rigid lower limb power-assisted exoskeletons are heavy and bulky, and are not lightweight and flexible, making them inconvenient for the elderly to use in daily activities. Utility Model Content

The present invention is described in detail below in conjunction with the drawings.

[0026] Example 1

[0027] like Figures 1 to 5 As shown, an airbag driving component includes a leg baseband 1, an air guide tube assembly 2, two L-shaped airbags 3 and a plurality of intermediate airbags 4, the two L-shaped airbags 3 and the plurality of intermediate airbags 4 are arranged in a row and at equal intervals on the back of the leg baseband 1, the two L-shaped airbags 3 are respectively arranged at the upper end and the lower end of the back of the leg baseband 1, one side of the L-shaped airbag 3 is fixedly connected to the leg baseband 1, and the other side of the L-shaped airbag 3 is a free end, the plurality of intermediate airbags 4 are located between the two L-shaped airbags 3, one end edge of the intermediate airbag 4 is movably connected to the leg baseband 1, and the two L-shaped airbags 3 and the plurality of intermediate airbags 4 are respectively connected to an air source through the air guide tube assembly 2. Specifically, when using the embodiment of the present application, an airbag driving component of the embodiment of the present application is arranged on each thigh, and the airbag driving component is arranged on the back of the human thigh, and the leg base band 1 fits closely to the back of the human thigh. Preferably, the upper end of the leg base band 1 is located at the buttocks or the waist or between the two; when the L-shaped airbag 3 and the middle airbag 4 are not inflated with gas, the airbags are not squeezed against each other; when working, the gas source inputs gas into the upper L-shaped airbag 3 through the air guide tube assembly 2 for inflation, and the gas then enters the multiple middle airbags 4 for inflation, and finally enters the lower L-shaped airbag 3 for inflation. The upper ends of the L-shaped airbag 3 and the leg base band 1 are located at the buttocks or the waist or between the two, that is, the upper L-shaped airbag 3 is also located there. When the L-shaped airbag 3 is inflated, The fixed end (the side where the L-shaped airbag 3 is fixedly connected to the leg base band 1) and the free end (the other side of the L-shaped airbag 3) of the L-shaped airbag 3 expand simultaneously, but the fixed end is constrained by the leg base band 1 and can therefore only expand outward, and the free end of the L-shaped airbag 3 is simultaneously subjected to squeezing forces from the intermediate airbag 4 and the fixed end of the L-shaped airbag 3, thereby transferring the force (torque) to the fixed end. In other words, the fixed end of the L-shaped airbag 3 provides a good fulcrum for the driving array. Furthermore, a plurality of intermediate airbags 4 expand sequentially from top to bottom in the arrangement direction, squeezing each other to generate squeezing forces, forming a bridge-type continuous structure that can transmit force. Under the bridge-type continuous structure that can transmit force, force is transmitted from the waist or buttocks to the legs, assisting the user in lifting their thighs and achieving walking assistance, with a novel structure.

[0028] In this embodiment, the upper and lower ends of the front end surface of the leg base band 1 are respectively provided with leg fixing straps 5. Preferably, the leg fixing straps 5 are elastic straps or cloth straps. Of course, the two ends of the leg fixing straps 5 can be detachably connected to the leg base band 1, or one end of the leg fixing straps 5 can be detachably connected to one side of the leg base band 1, and the other end of the leg fixing straps 5 can be fixedly connected to the other side of the leg base band 1. The detachably connected leg fixing straps 5 are convenient for adjusting the connection position between the leg fixing straps 5 and the leg base band 1 according to different thigh sizes, and are flexible to use. The leg fixing straps 5 and the leg base band 1 can be detachably connected using conventional techniques such as adjustment buckles and locks; when elastic straps are used, the two ends of the leg fixing straps 5 can also be fixedly connected to the leg base band 1, which can adapt to thighs of different sizes.

[0029] In this embodiment, a plurality of movable brackets 6 are also movably arranged on the back of the leg base band 1, and the plurality of movable brackets 6 are arranged in a row at equal intervals, and the movable brackets 6 correspond to the intermediate airbags 4 one by one, and the movable brackets 6 are connected to one end edge of the intermediate airbags 4. Preferably, the intermediate airbags 4 are rectangular, elliptical or circular. Specifically, under the above arrangement, the movable brackets 6 can be movably connected to the back of the leg base band 1, and the movable brackets 6 are connected to the intermediate airbags 4 one by one. When the intermediate airbags 4 are inflated, it is convenient for the multiple intermediate airbags 4 to move and squeeze each other.

[0030] In this embodiment, the movable bracket 6 includes two movable connecting members 7 arranged opposite to each other. One end of the two movable connecting members 7 can be connected to the back of the leg base band 1 by sewing. A connection gap is formed between the other ends of the two movable connecting members 7. The edge of one end of the two intermediate airbags 4 is connected to the connection gap formed between the other ends of the two movable connecting members 7. Specifically, the airbag is formed by hot-pressing and bonding two pieces of non-retractable TPU flexible fabric. The side of the airbag penetrates the airway of the airway assembly 2 to achieve the expansion and contraction of the airbag. The outer edge of the airbag is sealed by hot-pressing bonding and then connected to the connection gap formed between the other ends of the two movable connecting members 7. The installation is accurate and convenient. Preferably, the movable connecting member 7 is a deformable material, such as TPU flexible fabric.

[0031] In this embodiment, the two movable connecting members 7 are arranged in a triangle. Specifically, the above arrangement is conducive to improving the stability and reliability of the connection between the movable connecting member 7 and the intermediate airbag 4.

[0032] Example 2

[0033] The difference between the second embodiment and the first embodiment is that the movable connecting member 7 is made of flexible cloth.

[0034] Example 3

[0035] The difference between the present embodiment 3 and the embodiment 1 is that the movable connecting member 7 is made of elastic material. Specifically, the movable connecting member 7 made of elastic material has elastic recovery ability, so that when the L-shaped airbag 3 and the middle airbag 4 expand and squeeze each other, the movable connecting member 7 is deformed under its elasticity, and when the L-shaped airbag 3 and the middle airbag 4 shrink, the movable connecting member 7 drives the middle airbag 4 to return to its original position under its elastic recovery force.
