[0013] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] The present invention provides a walking aid, comprising: a support component 100, a transmission component 200 and a motor 300, wherein the support component 100 is sleeved on the user's legs, the motor 300 is used to provide power to make the support component 100 swing and thus drive the user's legs to walk, and the transmission component 200 is used to control the support component 100 to be separated from the power of the motor 300, and can also make the support component 100 connect with the power of the motor 300.

[0015] The support assembly 100 includes an upper support member 110 and a lower support member 120, and one end of the upper support member 110 is hinged to one end of the lower support member 120, and both the upper support member 110 and the lower support member 120 include two opening and closing members 111, the opening and closing members 111 are arc-shaped, and the concave surfaces of the two opening and closing members 111 are arranged opposite to each other, and one end of one opening and closing member 111 is hinged to one end of the other opening and closing member 111, and the other ends of the two opening and closing members 111 are connected to each other through buckles 112. A receiving space 113 is formed between the two opening and closing members 111, and the receiving space 113 can be used for the user to place the legs therein, so that the support assembly 100 is fixed to the user's legs.

[0016] In order to facilitate the disassembly and assembly of the support assembly 100, the opening and closing member 111 is designed as follows:

[0017] The opening and closing member 111 includes a legging portion 1111, a connecting mechanism 1112 and a mounting portion 1113. The legging portion 1111 is provided with a mating opening 1111a. The connecting mechanism 1112 includes a flip rod 1112a and a connecting switch 1112b. The flip rod 1112a is Z-shaped. The top end of the flip rod 1112a is embedded in the mating opening 1111a. The inflection point of its bottom is pivotally connected to the mounting portion 1113. The connecting switch 1112b presses against the bottom end of the flip rod 1112a.

[0018] The transmission assembly 200 includes a first transmission plate 210, a second transmission plate 220 and a clutch switch 230. The first transmission plate 210 is rotatably fixed to the upper support member 110, the second transmission plate 220 is fixedly connected to the lower support member 120, the second transmission plate 220 is transmission-connected to the first transmission plate 210, and the clutch switch 230 drives the first transmission plate 210 to clutch the second transmission plate 220.

[0019] The first transmission disk 210 includes: a base disk 211, a connecting ring 212, a diaphragm spring 213 and a cover ring 214. A base shaft 211a extends from the center of one end of the base disk 211, and the base shaft 211a is rotatably fixed to the lower support member 120. A mating surface is formed at the other end of the base disk 211, and the connecting ring 212 is fixed to the mating surface, and an interlayer is present between the connecting ring 212 and the mating surface. The end of the connecting ring 212 away from the mating surface is fixedly connected to the cover ring 214, and the connecting ring 212 and the cover ring 214 clamp and fix the outer edge of the diaphragm spring 213. The second transmission disk 220 is arranged in the interlayer, and a connecting shaft 221 extends from one end of the second transmission disk 220, and the connecting shaft passes through the connecting ring 212, the diaphragm spring 213 and the cover ring 214 in sequence, and the free end of the connecting shaft 221 is fixedly connected to the lower support member 120.

[0020] The clutch switch 230 includes a base 231, a button 232 and a return spring 233. The base 231 is annular and fixed to the upper support 110. The button 232 is coaxially built into 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. The other end of the return spring 233 presses against the telescopic end of the diaphragm spring 213. At the same time, a clamping groove is provided on the inner side of the base 231, and the clamping groove 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. When the button 232 is pressed and rotated, the clamping end is embedded in the bottom end of the L-shaped clamping groove, so that the pressing end presses the telescopic end of the diaphragm spring 213, thereby pushing the second transmission disk 220 toward the base disk 211, so that the second transmission disk 220 is pressed against the base disk 211, so that the first transmission disk 210 drives the second transmission disk 220 to rotate through friction force, thereby driving the lower support member 120 to swing.

[0021] It should be noted here that the second transmission disc 220 is disposed between the interlayer of the connecting ring 212 and the cover ring 214. When the user relies on human power to walk and needs to disconnect from the power, 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, so that the walker is disconnected from the power and allows the user to walk with human power. In contrast to the above process, when the user needs to connect to the power for assisted walking, the clutch switch 230 drives the diaphragm spring 213 to deform, and then pushes the second transmission disc 220 toward the first transmission disc 210, and makes the second transmission disc 220 press against the mating surface, so that the first transmission disc 210 drives the second transmission disc 220 under the action of friction.

[0022] The motor 300 preferably adopts a DC servo motor, which is powered by a battery. The motor 300 rotates back and forth, thereby driving the lower support member 120 to swing back and forth. As for the transmission method of the motor 300 and the transmission assembly 200, in principle, there is no restriction, and any transmission method that can drive the first transmission disk 210 to rotate is feasible.

[0023] Since people need to swing their legs back and forth when walking, this means that the first transmission disc 210 needs to rotate back and forth. The servo motor itself can achieve reciprocating rotation, but it is inevitable that the motor 300 itself will cause vibrations when it rotates back and forth continuously. To address this problem, a reversing mechanism is provided between the motor 300 and the base shaft 211a. The reversing mechanism includes: a sun gear 410, a planetary gear 420 and a connecting rod 430. The sun gear 410 is fixedly connected to the output end of the motor 300, the planetary gear 420 is meshed with the sun gear 410, and the two ends of the connecting rod 430 are respectively connected to the axis between the sun gear 410 and the planetary gear 420. The base shaft 211a extends radially outward with a swing rod 440, and the free end of the swing rod 440 is fixed to one side end face of the planetary gear 420. It should be noted here that the free end of the rocker arm 440 should be rotatably fixed to the end face of the planetary gear 420, and the connection point between the rocker arm 440 and the planetary gear 420 cannot be set on the rotating shaft of the planetary gear 420, otherwise the reversing mechanism will get stuck.

[0024] The upper support 110 and the lower support 120 are hinged to each other, and a receiving space is formed in both the upper support 110 and the lower support 120 for placing the user's legs, so that the walker is fixed to the human leg, and the human knee is at the hinge between the upper support 110 and the lower support 120. The second transmission disc 220 is fixedly connected to the lower support 120, and the motor 300 drives the first transmission disc 210 to rotate back and forth, thereby driving the second transmission disc 220 to rotate, and finally driving the lower support 120 to swing back and forth along the hinge. At the same time, the clutch switch 230 can be pressed to drive the first transmission disc 210 and the second transmission disc 220 to be clutched, so that power-assisted walking and mode switching relying on human walking can be realized. Using the walker of the present invention, the motor 300 can be used to drive the lower support 120 to swing back and forth, thereby driving the user's legs to swing, thereby effectively reducing the physical strength consumed by the user in walking.

[0025] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
