[0017] The present invention provides an omnidirectional and stable walking-assist robot for the elderly. It has the following beneficial effects: 1. The elderly person uses an omnidirectional stable walking-assist robot. The inner concave surfaces of the first rotating wall and the second rotating wall are in contact with the elderly person's legs, preventing the first rotating wall and the second rotating wall from causing a greater sense of pressure on the legs. The damping rotator drives the second rotating wall to rotate, so that the elderly person's legs are supported to sit up. Multiple damping rotators control the triangular support plate, the first rotating wall and the second rotating wall to rotate in a coordinated manner, so that the elderly person is in a walking state. The alternative strap method is not easy to dislocate, making the elderly person safer to walk, and solves the problem that the buckle binding method will cause discomfort to the user and is easy to separate, causing the elderly to fall.

[0018] 2. The elderly man uses an all-round stable walking-assist robot. The large area of ​​silicone shoe covers and the pressure of elastic strips make the elderly man feel less oppressive when using it, and the elderly man's shoes are not easily dislocated from the soleplate. The elderly man's legs pass through the steel wire at this time. The surface of the steel wire is covered with a thermal insulation plastic layer. The two ends of the plastic-dipped steel wire are pulled by the wire feeder to adjust the diameter of the steel wire winding. The contraction of the steel wire makes the elderly man's legs contact the second turning wall more closely and is not easily dislocated. The elderly man's feet and legs are in close contact with the walking structure, and because of the large area of ​​contact, the elderly man feels better when using it.

[0019] 3. The elderly person uses an all-around stable walking-assist robot. The armrest assembly rotates so that the elderly person is supported when sitting up, preventing him from becoming unstable and falling down. When walking, the elderly person holds the armrest assembly and wraps the elastic belt around his back. Since the elderly person cannot be in an upright position when walking and leans forward at a certain angle, the coordination of the branch pipe, front wheel and rear wheel allows the elderly person to be stably protected when walking forward. The soft support of the rubber curved plate makes the elderly person feel better when using it, preventing the elderly person from becoming unstable and falling down, solving the problem of not being able to provide all-around protection according to the elderly person's usage situation.

[0020] 4. The elderly man uses an all-around stable walking robot. The pulling rope is set between the connecting curved plate and the winding roller. The connecting curved plate is close to the elderly man's abdomen. The shortening of the pulling rope gives the elderly man an upward pulling force, thereby counteracting the gravity when the elderly man stands up, avoiding the problem of difficulty in getting up and easy falling when using the walking robot.

[0021] 5. The elderly man uses an all-round stable walking-assist robot. The more turns of the steel wire, the less squeezed the elderly man feels, and the less likely the elderly man's legs are to be misaligned with the first and second rotating walls. A rubber handle is fixedly connected to the surface of the bending tube away from the electric cylinder. The electric cylinder makes the bending tube retractable. The elderly man holds the rubber handle to gain leverage to stand up. The length of the bending tube and the diameter of the steel wire ring can be adjusted to meet the usage needs of different elderly people, making the all-round protection effect of the elderly better.

The surfaces of the first rotating wall 53 and the second rotating wall 54 are both concave.

[0026] The shoe of the elderly is inserted into the foot connection assembly 51, and the foot connection assembly 51 covers the shoe of the elderly. The inner concave surface of the first rotating wall 53 and the second rotating wall 54 contacts the leg of the elderly, preventing the first rotating wall 53 and the second rotating wall 54 from causing a greater pressure on the leg. The damping rotator 57 drives the second rotating wall 54 to rotate, so that the leg of the elderly is supported to sit up. The multiple damping rotators 57 control the triangular support plate 52, the first rotating wall 53 and the second rotating wall 54 to rotate in coordination, so that the elderly is in a walking state. The alternative strap method is not easy to be dislocated, making the elderly safer to walk, and solves the problem that the buckle binding method causes discomfort to the user and is easy to separate, causing the elderly to fall.

[0028] When in use, a magnetic plate is fixedly connected to the top of the bottom plate 511 near the silicone shoe cover 513. The magnetic plate and the magnetic plate 514 are magnetically attracted to each other, so that the silicone shoe cover 513 is restricted on the top of the bottom plate 511. Preferably, the magnetic plate 514 is connected to the bottom plate 511 by bolts. The elderly's shoes are inserted into the silicone shoe cover 513, and then the elastic pressure strip 515 is pressed to limit the silicone shoe cover 513. The large area of ​​the silicone shoe cover 513 is combined with the pressure of the elastic pressure strip 515, so that the elderly feel less oppression when using it. In addition, the elderly's shoes are not easily misaligned with the sole plate 511. The elderly's legs are now passing through the steel wire 554. The surface of the steel wire 554 is covered with a heat-insulating plastic layer. The two ends of the plastic-dipped steel wire 554 are pulled and stressed by the wire feeder 553, thereby adjusting the diameter of the wound steel wire 554. The rotating roller 551 makes the resistance smaller when the diameter of the steel wire 554 is adjusted. The contraction of the steel wire 554 makes the elderly's legs more closely contact with the second rotating wall 54 and not easily misaligned. The elderly's feet and legs are in close contact with the walking structure, and because of the large-area contact, the elderly have a better sense of use.

[0030] When in use, the elderly person's feet are limited by the foot connection assembly 51, the elderly person's calves are close to the first rotating wall 53, and the elderly person's thighs are close to the second rotating wall 54. The first rotating wall 53 and the second rotating wall 54 enable the elderly person to be supported when walking. In this process, the connecting curved plate 56 is fixedly connected to the pulling assembly 33, and the elderly person holds the surface of the armrest assembly 31. The first rotating wall 53 and the second rotating wall 54 rotate to enable the elderly person to sit up. In this process, the armrest assembly 31 rotates to support the elderly person when sitting up, preventing the elderly person from becoming unstable and falling when sitting up. When walking, the elderly person holds the armrest assembly 31 and wraps the elastic belt 6 around the elderly person's back. Since the elderly person cannot be in an upright position when walking and leans forward at a certain angle, the cooperation of the branch pipe 2, the front wheel 1 and the rear wheel 4 is used to ensure that the elderly person can be stably protected when leaning forward to walk. The soft support of the rubber curved plate 35 makes the elderly person feel better when using it, and prevents the elderly person's upper body from becoming unstable and falling, solving the problem of not being able to provide all-round protection according to the elderly person's usage.

One end of the pulling rope 334 is fixedly mounted on the surface of the winding roller 333, and the other end of the pulling rope 334 is fixedly mounted on the surface of the connecting bent plate 56.

[0032] When in use, the elderly sit on the edge of the bed with their legs bent. It is difficult for them to stand up by themselves, and they are easily driven to lose stability and fall by the first rotating wall 53 and the second rotating wall 54. In this device, the electric turntable 313 drives the inner rotating drum 312 to rotate, so that the electric cylinder 314 rotates its axis parallel to the ground. At this time, the end face of the bending tube 315 is close to the elderly. The elderly hold the bending tube 315 with their hands. Then, the electric turntable 313 drives the inner rotating drum 312 to rotate in the opposite direction, and the electric cylinder 314 rotates in the opening shell 311.

[0034] When in use, the plastic plate 555 is sleeved on the surface of the steel wire 554, and then heated to make the plastic sheet 556 and the plastic plate 555 glued together. When the elderly's legs pass through the steel wire 554, the wire feeder 553 controls the steel wire 554 to be in an expanded state. The diameter of the steel wire 554 loop is large, so that the elderly's legs are not disturbed when passing through. Subsequently, the steel wire 554 is driven to tighten, and the plastic plates 555 are driven to move closer to each other. The plastic sheet 556 is set between the elderly's legs and the steel wire 554 to prevent the elderly's legs from being disturbed when in use. The elderly will feel uncomfortable due to being squeezed. The more turns of the steel wire 554, the less squeezed the elderly will feel, and the elderly's legs will be less likely to be misaligned with the first rotating wall 53 and the second rotating wall 54. A rubber handle is fixedly connected to the surface of the bending tube 315 away from the electric cylinder 314. The electric cylinder 314 makes the bending tube 315 retractable. The elderly can hold the rubber handle to gain leverage to stand up. The length adjustment of the bending tube 315 and the adjustable diameter of the steel wire 554 can meet the usage needs of different elderly people, making the all-round protection effect of the elderly better.
