An accommodating space 113 is formed between the two opening and closing members 111, and the accommodating space 113 can be used for a user to place a leg therein, so that the support assembly 100 is fixed on the leg of the user.

In order to facilitate the disassembly and assembly of the supporting component 100, the opening and closing piece 111 is designed as follows:

opening and shutting 111 includes puttee portion 1111, coupling mechanism 1112 and installation department 1113, and puttee portion 1111 has seted up cooperation mouth 1111a, coupling mechanism 1112 includes upset pole 1112a and linked switch 1112b, and upset pole 1112a is the zigzag, and upset pole 1112a top is inlayed and is located cooperation mouth 1111a, and the flex point pin joint in installation department 1113 of its bottom, and linked switch 1112b supports the bottom of pressing upset pole 1112 a.

The transmission assembly 200 comprises a first transmission disc 210, a second transmission disc 220 and a clutch switch 230, wherein the first transmission disc 210 is rotatably fixed on the upper support member 110, the second transmission disc 220 is fixedly connected with the lower support member 120, the second transmission disc 220 is in transmission connection with the first transmission disc 210, and the clutch switch 230 drives the first transmission disc 210 to be in clutch connection with the second transmission disc 220.

The first transfer disk 210 includes: the base plate 211, the connecting ring 212, the diaphragm spring 213 and the cover ring 214, wherein a base shaft 211a extends from the center of one end of the base plate 211, the base shaft 211a is rotatably fixed on the lower supporting member 120, a matching surface is formed at the other end of the base plate 211, the connecting ring 212 is fixed on the matching surface, an interlayer is arranged between the connecting ring 212 and the matching surface, one end of the connecting ring 212, which is far away from the matching surface, is fixedly connected with the cover ring 214, the connecting ring 212 and the cover ring 214 are clamped and fixed on the outer edge of the diaphragm spring 213, the second transmission disc 220 is arranged on the interlayer, a connecting shaft 221 extends from one end of the second transmission disc 220, the connecting shaft sequentially penetrates through the connecting ring 212, the diaphragm spring 213 and the cover ring 214.

The clutch switch 230 includes a base 231, a button 232 and a return spring 233, the base 231 is annular, the base 231 is fixed on the upper support 110, the button 232 is coaxially disposed in the base 231, the button 232 extends to form a pressing end, one end of the return spring 233 is fixedly connected to the pressing end, and the other end of the return spring 233 presses the telescopic end of the diaphragm spring 213. Meanwhile, a clamping groove is formed in the inner side of the base 231 and is L-shaped, a clamping end is formed on the outer side of the button 232, and the clamping end is embedded in the clamping groove. And will press when button 232 to the rotary button 232 causes the bottom in joint end embedding L shape joint groove, thereby makes to support the flexible end that presses diaphragm spring 213 of holding the end, thereby pushes second driving plate 220 to basal disc 211, makes second driving plate 220 support and presses in basal disc 211, thereby first driving plate 210 drives second driving plate 220 through frictional force and rotates, thereby drives support piece 120 swing down.

It should be noted here that the second transmission disc 220 is disposed between the connection ring 212 and the cover ring 214, and when the user needs to remove the power depending on the manual walking, the diaphragm spring 213 is in a natural state, and the size of the interlayer is slightly larger than the thickness of the second transmission disc 220, so that a gap is left between the first transmission disc 210 and the second transmission disc 220, thereby removing the power of the walking aid and allowing the user to walk by using the manual walking. Contrary to the above process, when power is needed to connect and power is needed to perform power-assisted walking, the clutch switch 230 drives the diaphragm spring 213 to deform, then the second transmission disc 220 is pushed to the first transmission disc 210, the second transmission disc 220 is pressed against the matching surface, and the first transmission disc 210 drives the second transmission disc 220 under the action of friction force.

The motor 300 is preferably a dc servo motor, and the battery supplies power to the motor 300, so that the motor 300 rotates reciprocally to drive the lower support member 120 to swing reciprocally, and the transmission mode of the motor 300 and the transmission assembly 200 is not limited in principle, and the transmission mode capable of driving the first transmission disc 210 to rotate is also applicable.

Since the walking of the person requires the reciprocating swing of the legs, which means that the first driving disk 210 needs to be rotated back and forth, the servo motor itself can realize the reciprocating rotation, but it is inevitable that the continuous reciprocating rotation of the motor 300 itself will also cause the vibration. To solve this problem, a reversing mechanism 400 is disposed between the motor 300 and the base shaft 231, and the reversing mechanism 400 includes: the motor comprises a sun gear 410, a planetary gear 420 and a connecting rod 430, wherein the sun gear 410 is fixedly connected with the output end of the motor 300, the planetary gear 420 is meshed with the sun gear 410, two ends of the connecting rod 430 are respectively connected with the axes between the sun gear 410 and the planetary gear 420, a swing rod 440 extends outwards from the base shaft 211a in the radial direction, and the free end of the swing rod 440 is fixed on one side end face of the planetary gear 420. It should be noted here that the free end of the swing link 440 should be rotatably fixed to the end surface of the planetary gear 420, and the connection point of the swing link 440 and the planetary gear 420 cannot be arranged on the rotation shaft of the planetary gear 420, otherwise the reversing mechanism 400 would be locked.

The upper support 110 and the lower support 120 are hinged to each other, and a receiving space is formed in each of the upper support 110 and the lower support 120 for receiving the leg of the user, thereby fixing the walking aid to the leg of the person with the knee of the person at the hinge of the upper support 110 and the lower support 120. The second driving plate 220 is fixedly connected to the lower supporting member 120, and the motor 300 drives the first driving plate 210 to rotate in a reciprocating manner, so as to drive the second driving plate 220 to rotate, and finally drive the lower supporting member 120 to swing in a reciprocating manner along the hinge. Meanwhile, the clutch switch 230 can be pressed to drive the first transmission plate 210 and the second transmission plate 220 to be separated and combined, so that power-assisted walking and mode switching depending on manual walking can be realized. By using the walking aid of the invention, the motor 300 can be used for driving the lower support piece 120 to swing back and forth, so that the legs of a user can be driven to swing, and the physical strength consumed by the user in walking can be effectively reduced.

The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the protection scope of the claims of the present invention.
