For example, as shown in Figures 1 and 2, the walking aid has two modes of operation, an automatic movement mode and a manual movement mode.

When the walking aid is in the automatic motion mode, the operating state of the active wheel assembly 100 is regulated by the master control assembly 300, so that the active wheel assembly 100 drives the driven wheel assembly 200 to operate, thereby coordinating the user's movement state and reducing the difficulty of the user's walking . Specifically, the number of the active wheel assemblies 100 can be set to two groups, and the main control assembly 300 realizes the forward, backward, left and right directions of the walking device by regulating the speed and the running direction of the two groups of active wheel assemblies 100 . Movement to the right. Further, the main control assembly 300 can be set as a sensor device such as an infrared sensor, a ranging sensor or an ultrasonic sensor, so as to detect the user's movement state and movement trend, and then regulate the operation state of the active wheel assembly 100; or, the main control assembly 300 can be set to It is a rocker 320 or several buttons, so that the user can control the operation state of the active wheel assembly 100 through the rocker 320 or buttons.

When the walking aid is in the manual motion mode, the auxiliary wheel assembly 400 is driven to descend by the lifting assembly 500, so that the auxiliary wheel assembly 400 is in contact with the ground, and the relative height of the active wheel assembly 100 is raised, and the active wheel assembly 100 is not connected to the ground. ground contact. At this time, the auxiliary wheel assembly 400 and the driven wheel assembly 200 cooperate with each other, and the user can manually push the frame assembly 600 to make the auxiliary wheel assembly 400 and the driven wheel assembly 200 roll and move, so as to achieve the effect of walking. .

Further, in this mode, the driving wheel 110 and the driven wheel assembly 200 cooperate together.

When the walking aid is in the fully automatic motion mode, the camera component 330 monitors the user's movement angle and transmits the first driving signal to the main control center 310 ; the sensor component 340 monitors the user's movement speed and transmits it to the main control center 310 The second drive signal; the main control center 310 transmits a second trigger signal to the motor 120 according to the first drive signal and the second drive signal, so that the motor 120 automatically adjusts the corresponding operating state according to the second trigger signal, thereby regulating the driving wheel The running direction and running speed of 110 make the walking device realize the function of moving forward, backward, left and right. Since the user does not need to perform any operation during this process, the camera assembly 330 and the sensor assembly 340 can monitor the user's movement state and movement trend, thereby regulating the movement of the active wheels 110 and improving the user's experience. Further, by setting the first button, the user can control the switches of the camera assembly 330 and the sensor assembly 340 through the first button, so as to facilitate the transition between the semi-automatic motion mode and the fully automatic motion mode.

When the walking device is in the manual motion mode, the drive unit 550 drives the gear 530 to rotate, thereby driving the rack 520 to slide down on the guide rail 540, and at the same time, the rack 520 drives the connecting piece 420 to move downward, so that the auxiliary wheels 430 is in contact with the ground while raising the relative height of the active wheels 110 without the active wheels 110 in contact with the ground. At this time, the auxiliary wheel 430 and the driven wheel assembly 200 work together, so that the user can manually push the frame assembly 600 to make the auxiliary wheel 430 and the driven wheel assembly 200 roll and move, so as to achieve the effect of walking.

In addition, when the walking aid is in the fixed mode, the push rod assembly 130 drives the motor 120 to rise, thereby driving the driving wheel 110 to rise, so that the driving wheel 110 does not contact the ground, while the fixed frame 140 contacts the ground. The wheel 430 is not in contact with the ground, so that the fixing frame 140 effectively fixes the position of the walking aid, restricts the movement of the driven wheel assembly 200, and prevents the moving of the walking aid. Then, the seat 710 and the second positioning member 740 are buckled and connected, so that the seat 710 is in a horizontal state, which is convenient for the user to sit on the seat 710 for rest, which improves the function of the walking aid and improves the user's experience in use. . Further, by setting the second button, the user can control the operation of the push rod assembly 130 through the second button.
