[0025] By adopting the above technical solution, by setting the chair body, when the user sits on the chair body, at this time the user can control the driving motor to work through the controller, so that the driving shaft of the driving motor can drive the rotating wheel to rotate. Since the rotating wheel is rotatably installed with the crawler, the crawler can move on the ground.

[0026] Preferably, connection grooves are formed on both the left and right sides of the mounting frame, the connection grooves communicate with the rotating groove, gears are arranged inside the connection grooves, the gears are installed on the outer wall surface of the rotating rod, adjusting plates are arranged on both the left and right sides of the mounting frame, fixing plates are arranged on both the left and right sides of the adjusting plates, a tooth groove is formed on one side of the adjusting plate, and the tooth groove meshes with the gear.

Then the gyroscope sensor can control the lead screw slide table to work, so that the slide table of the lead screw slide table can drive the connecting rod to move through the mounting plate, thereby adjusting the position of the chair body on the top surface of the mounting frame. When the crawler moves up and down on the stairs, the center of gravity position of the mounting frame can be adjusted, enhancing the comfort of the user when sitting.

[0034] Preferably, support grooves are respectively opened on the left and right sides of the mounting frame. One end of the rotating wheel is fixedly connected with a support ring, and the support ring is rotatably installed with the support groove.

[0036] In summary, the present invention mainly has the following beneficial effects:

[0037] 1. By setting up the chair body, when the user sits on the chair body, the user can control the driving motor to work through the controller at this time, so that the driving shaft of the driving motor can drive the rotating wheel to rotate. Since the rotating wheel is rotatably installed with the crawler, the crawler can move on the ground. By setting up the gyroscope sensor, when the crawler moves up and down on the stairs, the gyroscope sensor can detect the center of gravity of the chair body at this time. At this time, the gyroscope sensor can control the screw slide table to work, so that the slide table of the screw slide table can drive the connecting rod to move through the mounting plate, thereby adjusting the position of the chair body on the top surface of the mounting frame, so that when the crawler moves up and down on the stairs, the center of gravity position of the mounting frame can be adjusted, and the comfort of the user when sitting can be improved;

[0038] 2. By setting up the crawler, when the crawler moves on the uneven road surface, if the bottom surface of the mounting frame is about to touch the ground, the user can control two servo motors to work through the controller at this time, so that the driving shaft of the servo motor can drive the rotating rod to rotate. At this time, the mounting block can move on the bottom surface of the mounting frame, thereby taking in and releasing the crawler. When the rotating rod rotates, it can drive the gear to rotate. Since the gear meshes with the tooth groove, the rotating rod can drive the adjusting plate to move when rotating, thereby adjusting the positions of several pressing wheels, so that the pressing wheels can move downward, so as to increase the height between the mounting frame and the ground, avoid the bottom surface of the mounting frame from touching the ground, improve the service life of the mounting frame, and at the same time can move on different terrains, thereby increasing the walking range, so that the user can go to any place he wants to go by himself.
