A slider 53 is mounted on the lead screw 52. A drive motor 54 is mounted on one of the fixed blocks 51 via a mounting bracket. The drive end of the drive motor 54 passes through the fixed block 51 and is connected to the lead screw 52. A locking block 55 is rotatably sleeved on the slider 53. A baffle 531 is provided on the opposite side of the slider 53 and is respectively attached to the locking block 55. A seating plate 56 is mounted on the locking block 55. A first locking structure 57 and a second locking structure 58 are respectively provided on one of the handrails 4 and the seating plate 56.

[0036] The first locking structure 57 includes: a fixing rod 571, a connecting block 572, a female pin 573, and a male pin 574.

[0037] The fixed rod 571 is installed on one of the handrails 4. Two connecting blocks 572 are slidably installed on the fixed rod 571 and located above the lead screw 52. The two connecting blocks 572 are connected by a guide rod. The seating plate 56 is located on the opposite side of the two connecting blocks 572. The female pin 573 and the male pin 574 are respectively installed on the connecting block 572 and the seating plate 56. The seating plate 56 is locked by the female pin 573 and the male pin 574.

[0038] The second locking structure 58 includes: two connecting blocks 581, a stop block 582, a telescopic rod 583, a limit block 584, and a spring 585.

[0043] Specifically, when a patient needs to use this invention for walking, firstly, the patient holds the support platform 33 or supports themselves on the support platform 33 with their arm, and finally, the patient applies a pushing force with their hand or body to move.

[0044] When a patient needs to ride in this utility model, firstly, the male pin 574 is separated from the female pin 573. Secondly, the riding plate 56 is rotated, which in turn causes the locking block 55 to rotate on the slider 53. At the same time, the riding plate 56 drives the second locking structure 58 to rotate. When the limiting block 584 rotates to contact the limiting rod 41, the riding plate 56 continues to rotate. At this time, the limiting block 584 gradually moves, which in turn causes the telescopic end of the telescopic rod 583 to retract. At the same time, the spring 585 is compressed. When the limiting block 584 rotates to the limit... After the bottom of the positioning rod 41 is reached, the spring 585 rebounds, causing the telescopic rod 583 and the limiting block 584 to reset, thus locking the limiting rod 41 between the limiting block 584 and the stop block 582, preventing the seating board 56 from rotating. Next, the locking plate 64 is rotated to disengage it from the foot pedal 63. Then, the foot pedal 63 is rotated to rest on the seat 62. At this point, the patient can sit on the seating board 56 and place their feet on the foot pedal 63. Finally, the user pulls the lever to move the patient.

[0045] When it is necessary to adjust the seating plate 56 to a comfortable position, firstly, start the drive motor 54, which in turn drives the lead screw 52 to rotate, thereby driving the slider 53 to move, which in turn drives the baffle 531 to move, thereby driving the locking block 55, seating plate 56, first locking structure 57 and second locking structure 58 to move in sequence. After the seating plate 56 moves to a comfortable position, the seating plate 56 can be rotated to make it horizontal.

[0046] In summary, according to an embodiment of the present invention, an assistive device for helping the elderly stand and walk can, on the one hand, drive the seat plate 56 to move via the drive motor 54, thereby adjusting the position of the seat plate 56 and thus adjusting the comfort of the patient's body and feet when sitting; on the other hand, through the cooperation of the second locking structure 58 and the limiting rod 41, the seat plate 56 can maintain stability when the patient sits.
