A carrying component is provided on the support plate 3, a sitting-up component is provided on the fixing frame 2, and an auxiliary component is provided on the support plate 3.

[0021] The carrying component includes a third threaded rod 23 rotatably connected to the back of the support plate 3. The outer threads of the third threaded rod 23 are opposite in direction. Four movable blocks 25 are threadedly connected to the outer threads of the third threaded rod 23. The movable blocks 25 have a first threaded through hole threadedly connected to the third threaded rod 23. A guide rod 24 is fixedly connected to the inside of the support plate 3. A guide through hole of the same size as the guide rod 24 is opened inside the movable blocks 25. A fixing ring 17 is fixedly connected to the left side of the movable blocks 25. The fixing ring 17 is semi-circular. A first motor 4 is fixedly installed on the right side of the support base 1. A worm gear 5 is fixedly connected to the output shaft of the first motor 4. Two rotating cylinders 6 are rotatably connected to the inner bottom wall of the support base 1. A worm wheel 7 is fixedly connected to the outer side of the rotating cylinder 6. The worm gear 5 and the worm wheel 7 mesh with each other. A first threaded rod 8 is threadedly connected to the inside of the rotating cylinder 6. A threaded groove is opened inside the rotating cylinder 6 that is threadedly connected to the first threaded rod 8. One end of the first threaded rod 8 is fixedly connected to the bottom of the support plate 3.

[0022] It should be noted that by setting up the carrying component, when the elderly walk with the aid of walking, the cane can be placed on the left side of the support plate 3, and the two canes are fixed by four fixing rings 17 respectively, which makes it easy to carry the cane. In addition, the height of the support plate 3 can be adjusted according to the length of the cane, reducing the problem of the cane being blocked by ground obstacles and affecting the user's walking, making it convenient for the user to use.

[0023] Please see Figure 2-4The sitting assembly includes a fixed frame 2 with a fixed seat 9 slidably connected to its inner side. The inner walls of the front and back of the fixed frame 2 are provided with grooves. The front and back of the fixed seat 9 are fixedly connected with sliders that are slidably connected to the grooves. The inner side of the fixed seat 9 is rotatably connected to a seat plate 10. A second motor 16 is fixedly installed on the top of the fixed frame 2. The output shaft of the second motor 16 is fixedly connected to a second threaded rod 18. The inside of the fixed seat 9 is provided with a second threaded through hole that is threadedly connected to the second threaded rod 18. A support frame 11 is fixedly connected to the top of the fixed seat 9. A baffle 12 is slidably connected to the top of the support frame 11. The right side of the baffle 12 is inclined. Two telescopic rods 20 are fixedly connected to the top of the support frame 11. One end of the telescopic rod 20 is fixedly connected to the inner top wall of the baffle 12. A second spring 21 is sleeved on the outer side of the telescopic rod 20. One end of the second spring 21 is fixedly connected to the inner top wall of the baffle 12. The other end of the second spring 21 is fixedly connected to the top of the support frame 11.

[0024] When the seat 10 is rotated to a vertical position for storage, the seat 10 presses against the inclined surface of the baffle 12, pushing the baffle 12 to slide upward. When the seat 10 moves to the left side of the baffle 12, the tension of the second spring 21 drives the baffle 12 to reset, and the baffle 12 limits the seat 10.

[0025] It should be noted that by setting up the sitting-standing component, when the elderly person changes from a sitting to a standing position, the elderly person sits on the seat board 10 and is helped to stand up by moving the elderly person upward. The seat board 10 can also be flipped and stored to reduce the obstruction of the elderly person's movement.

[0026] Please see Figure 1-3 The auxiliary components include two movable slots 22 on the top of the support plate 3. A connecting plate 19 is slidably connected inside the movable slot 22. A handle 13 is fixedly connected to the inner side of the connecting plate 19. A locking rod 14 is slidably connected inside the connecting plate 19. The top of the support plate 3 has multiple slots that are adapted to the size of the locking rod 14. A first spring 15 is sleeved on the outer side of the locking rod 14. The two ends of the first spring 15 are fixedly connected to the top of the connecting plate 19 and the outer side of the locking rod 14, respectively.

[0027] It should be noted that, through the setting of auxiliary components, the position of handle 13 can be adjusted according to the user's needs, making it easier for the user to hold and support it.

[0028] The working principle of the above embodiments is as follows: This walking and sitting-up assistive device for the elderly allows the cane to be placed on the left side of the support plate 3 when the elderly are walking with the aid, positioning the cane inside the fixing ring 17. By rotating the third threaded rod 23, the guide rod 24 limits the movable block 25, causing the fixing ring 17 to move closer to the cane, clamping and securing it for easy carrying and placement. Furthermore, by activating the first motor 4, the output shaft of the first motor 4 drives the worm gear 5 to rotate, causing the worm wheel 7 meshing with the worm gear 5 to rotate through the rotating cylinder 6. This causes one end of the first threaded rod 8 to extend the support plate 3 upwards, adjusting the height of the support plate 3 according to the length of the cane, reducing the problem of the cane obstructing the user's walking due to ground obstacles. Additionally, when the elderly need to sit down to rest, they can pull the stop... The plate 12 moves upward, causing the telescopic rod 20 to extend and pull the second spring 21, so that the baffle 12 no longer restricts the seat plate 10. The seat plate 10 is rotated to be placed horizontally, making it easier for the elderly to sit on the seat plate 10 and change the elderly patient from a standing position to a sitting position. Then, by starting the second motor 16, the second threaded rod 18 is driven to rotate, which drives the fixed seat 9 to slide on the slide groove through the slider, and drives the seat plate 10 to move downward, so that the elderly patient can sit down slowly. It assists the elderly patient when getting up and sitting down. When the elderly person walks with the walker, the locking rod 14 is pulled to disengage it from the locking groove, which removes the restriction on the connecting plate 19 and allows the connecting plate 19 to slide inside the movable groove 22. The position of the handle 13 can be adjusted according to the user's needs, so that the user can hold it for support and make it convenient for the user to use.
