The roller column 105 is slidably connected to the support frame 101 and is located inside the support frame 101. The moving component 107 is located on the seat plate 104. On one side, the adjusting component 108 is located on the connecting shell 103, and the controller 109 is located on the side of the auxiliary arm 102 away from the connecting shell 103. When the elderly need to rest after walking for a long time, the moving component 107 is adjusted by the controller 109 to make the roller column 105 enter the interior of the support frame 101, and the contact between the roller column 105 and the ground is changed to the state where the fixed support leg 106 is in contact with the ground. Then, the adjusting component 108 is controlled by the controller 109 to make the adjusting component 108 adjust the seat board 104 to facilitate the elderly to sit on the seat board 104 and rest.

By starting the servo motor 117, the servo motor 117 drives the first threaded rod 110 to rotate. When the first threaded rod 110 rotates, it drives the rotating sleeve 114 to rotate, thereby driving the transmission belt 116 to run, and the transmission belt 116 drives the driven sleeve 115 to rotate. The second threaded rod 111 is rotated by rotating the driven sleeve 115, and the sliding sleeve 112 is moved downward on the first threaded rod 110 and the second threaded rod 111 by rotating the first threaded rod 110 and the second threaded rod 111 on the connecting shell 103. Under the action of the sliding sleeve 112, the connecting frame 113 rotates the seat plate 104 on the support frame 101, making the seat plate 104 perpendicular to the connecting shell 103, thereby realizing the adjustment of the seat plate 104, which is convenient for the elderly to rest after walking for a long time.

[0037] In this embodiment, the walking aid component also includes a pad 118 and a fixed column 119, one end of the fixed column 119 is fixedly connected to the support frame 101, and the other end of the fixed column 119 is fixedly connected to the auxiliary arm 102, the pad 118 is fixedly connected to the support frame 101, and is located below the seat 104, the pad 118 is used to support the seat 104, and the fixed column 119 is used to improve the stability of the auxiliary arm 102 and the support frame 101.

[0038] In this embodiment, the moving component 107 includes a driving motor 120, a rotating shaft 121, a supporting plate 122 and a cam 123. The supporting plate 122 is fixedly connected to the pad 118 and is located on one side of the pad 118. The rotating shaft 121 is rotatably connected to the supporting plate 122 and passes through the supporting plate 122. The driving motor 120 is fixedly connected to the rotating shaft 121 and is located on one side of the rotating shaft 121. The driving motor 120 is fixedly connected to the pad 118. The cam 123 is fixedly connected to the rotating shaft 121 and is located on a side of the rotating shaft 121 away from the driving motor 120. When the driving motor 120 is started, the rotating shaft 121 is driven by the driving motor 120 to rotate, so that the cam 123 rotates along with the rotating shaft 121, thereby indirectly adjusting the height of the roller column 105.

[0039] In this embodiment, the moving assembly 107 further includes an I-shaped frame 124, an adjusting rod 125 and an adjusting seat 126. The adjusting rod 125 is rotatably connected to the cam 123 and is located on one side of the cam 123. The adjusting seat 126 is movably connected to the adjusting rod 125 and is located on one side of the adjusting rod 125. The I-shaped frame 124 is fixedly connected to the adjusting seat 126 and is located on a side of the adjusting seat 126 away from the adjusting rod 125. The I-shaped frame 124 is fixedly connected to the roller column 105. Then, the rotation of the cam 123 drives the adjusting rod 125 to move, and at the same time, drives the adjusting seat 126 to move up and down. Through the up and down movement of the adjusting seat 126, the I-beam 124 is moved in the supporting frame 101, thereby adjusting the height of the roller column 105, so that the state in which the fixed support leg 106 is in contact with the ground is changed to the state in which the roller column 105 is in contact with the ground, making it easier for the elderly to push the auxiliary arm 102 to walk, thereby reducing the consumption of the elderly during walking.

[0040] When using the auxiliary walking device, when the elderly need to rest after walking for a long time, the drive motor 120 is started by the controller 109, and the drive motor 120 drives the rotating shaft 121 to rotate, so that the cam 123 rotates along with the rotating shaft 121, and the rotation of the cam 123 drives the adjusting rod 125 to move, and at the same time, drives the adjusting seat 126 to move upward. The upward movement of the adjusting seat 126 causes the I-shaped frame 124 to move upward in the support frame 101, so that the roller column 105 and the fixed support leg 106 are in contact with the ground. Then, the servo motor 117 is started by the controller 109, and the servo motor 117 drives the first threaded rod 110 to rotate. When the first threaded rod 110 rotates, it drives the rotating sleeve 114 to rotate, thereby driving the transmission belt 116 to run, and the transmission belt 116 drives the driven sleeve 115 to rotate. The rotation of the driven sleeve 115 causes the second threaded rod 111 to rotate, and the first threaded rod 110 and the second threaded rod 111 rotate on the connecting shell 103, so that the sliding sleeve 112 moves downward on the first threaded rod 110 and the second threaded rod 111. Under the action of the sliding sleeve 112, the connecting frame 113 causes the seat plate 104 to rotate on the support frame 101, and the seat plate 104 is perpendicular to the connecting shell 103, thereby realizing the adjustment of the seat plate 104, which is convenient for the elderly to rest after walking for a long time.

[0041] Second, see Figure 4 , the present invention also provides a walking aid assist device control system, the controller 109 includes a drive motor output module 127, a servo motor output module 128, a power supply module 129, a detection module 130 and a safety protection module 131;

[0042] The servo motor output module 128 is used to start the servo motor 117 and adjust the seat 104;

[0043] The driving motor output module 127 is used to start the driving motor 120 and adjust the height of the roller column 105;

[0044] The power supply module 129 is used to provide power for the operation of the device;

[0045] The detection module 130 is used to detect the operating status of the drive motor 120 and the servo motor 117;

[0046] The safety protection module 131 is configured to immediately cut off the power supply module 129 when the detection module 130 detects abnormal resistance in the operation of the drive motor 120 and the servo motor 117 .

[0047] Thirdly, please refer to Figure 5 The present invention also provides a method for controlling a walking aid device, comprising:

[0048] S1. Determine whether the current user needs to rest;

[0049] S2. If a break is needed, the controller 109 starts the drive motor 120, which drives the rotating shaft 121 to rotate, thereby causing the cam 123 to rotate along with the rotating shaft 121;

[0050] S3. The rotation of the cam 123 drives the adjustment rod 125 to move, and at the same time, drives the adjustment seat 126 to move upward. The upward movement of the adjustment seat 126 causes the I-shaped frame 124 to move upward in the support frame 101, so that the roller column 105 and the fixed support leg 106 are in contact with the ground;

[0051] S4. The servo motor 117 is then started by the controller 109. The servo motor 117 drives the first threaded rod 110 to rotate. When the first threaded rod 110 rotates, the rotating sleeve 114 is driven to rotate, thereby driving the transmission belt 116 to run. The transmission belt 116 drives the driven sleeve 115 to rotate. The rotation of the driven sleeve 115 causes the second threaded rod 111 to rotate.

[0052] S5. By rotating the first threaded rod 110 and the second threaded rod 111 on the connecting shell 103, the sliding sleeve 112 moves downward on the first threaded rod 110 and the second threaded rod 111. Under the action of the sliding sleeve 112, the connecting frame 113 rotates the seat plate 104 on the support frame 101, making the seat plate 104 perpendicular to the connecting shell 103, thereby achieving adjustment of the seat plate 104.
