The track device 6 is on both sides of the motion control device 7. The chair wheel is installed on both sides of the main body box 3. The track device 6 is on the inner side of the chair wheel. The track device 6 adopts electric transmission, and the chair wheel at the bottom of the chair wheel adopts electric and human power mixed transmission. The front of the main body box 3 is a leg and foot support device 2. Four lifting wheel devices 5 are installed in front of the motion control device 7, and four lifting wheel devices 5 are also installed at the back.

As a detailed description of the above scenario:

The structure of the main body box 3 includes: two circular holes at the front positions on both sides of the outside for installing the armrest devices 1 on both sides, a larger circular hole at the rear positions on both sides of the outside for installing the chair wheels, the rear is connected to the lighting and heating device 8, a backrest device 9 is installed at the rear position of the upper outside, the lower front position of the outside of the main body box 3 is connected to the leg support 50 device, and the bottom of the main body box 3 is directly connected to the motion control device 7.

The structure of the motion control box includes: a connecting head for docking with the crawler device 6 on both sides, and a protruding piece on the front and rear of the motion control box. The protruding parts and the front and rear non-protruding parts each have a connecting hole connected to the lifting wheel device 5. Therefore, the front and rear protruding parts are each connected to two lifting wheel devices 5, and the front and rear non-protruding parts are each connected to one lifting wheel device 5 on the left and right, totaling eight lifting wheel devices 5.

The structure of the lighting and heating device 8 includes: a connecting plate 13 connected to the main body box 3, two lamp holders 16 extending from the plate and extending through a certain bending to eventually be located behind the left and right armrests 47 and slightly higher than the backrest, and a lighting and heating lamp 11 that can be adjusted 360° in front is connected to the head of the bracket.

The structure of the lighting heating lamp 11 includes: a lighting rotating disk 12 parallel to the ground connected to the lamp stand 16 of the lighting device, and a light fixture 10 is installed on each of the opposite sides of the lighting rotating disk 12 and connected to the ring belt 15 in the middle of the cylindrical lamp through a rotating shaft 51. In the middle of the front is a square block-shaped adjustable high-power lighting lamp 14, and the heating lamp 11 is surrounded by the lighting lamp 14.

The structure of the lifting wheel device 5 includes: the lifting wheel connecting frame 26 at the top is responsible for connecting with the motion control device 7, the upper lifting rod 19 and the lower lifting rod 23 are installed in the lifting cylinder 24, wherein the upper lifting rod 19 is connected to the fixed shaft and installed in the lifting wheel connecting frame 26, the lower lifting rod 23 is connected to the lifting wheel retracting shaft 22, the upper lifting rod 19 and the lower lifting rod 23 are used to realize the lifting and lowering of the lifting wheel, the lifting wheel retracting shaft 22 is installed in the lifting wheel control frame 21, and the lifting wheel control frame 21 has a built-in motor to control the lifting and lowering of the lifting wheel. At the same time, the lifting wheel has a built-in pressure sensor.

In this embodiment, the process of going upstairs is explained by an example: when the wheelchair is about to go upstairs, the upstairs button 42 is pressed, and then the crawler device 6 rotates left and right in the opposite direction to realize the wheelchair turning 180 degrees clockwise in situ, so that the wheelchair faces the stairs. Then the upper half lifting rods 19 and the lower half lifting rods 23 of all lifting wheel devices 5 extend from both ends of the lifting rod sleeve 20 at the same time, and at the same time, the lifting wheel retracting shaft 22 of the lifting wheel control frame 21 starts to rotate to lower the lifting wheels, until the eight lifting wheel devices 5 reach the same horizontal plane and support the wheelchair, so that the wheelchair main box 3 and other devices are raised by 10 cm above the plane. After that, the wheelchair moves slowly until the lifting wheels 7 33 and 8 34 touch the step wall. At this time, the pressure sensors of the lifting wheels feel the side pressure, and the lifting wheels 1 27, 28, 39, 4 30, 5 31 and 6 32 continue to descend to support the wheelchair, so that the lifting wheels of the lifting wheels 7 33 and 8 34 are tangent to the second step surface, and then the wheelchair continues to move forward slowly until the lifting wheels 5 31 and 6 32 touch the step wall. At this time, the pressure sensors of the lifting wheels 5 31 and 6 32 feel the side pressure, and the upper lifting rods of the lifting wheels 5 31 and 6 32 are The upper and lower lifting rods 19 and the lower half lifting rod 23 are simultaneously retracted into the lifting rod sleeve 20 until the lifting wheels of the fifth lifting wheel 31 and the sixth lifting wheel 32 are tangent to the second step surface, and then the wheelchair continues to move forward slowly, and so on. When the seventh lifting wheel 33 and the eighth lifting wheel 34 touch the step wall, the movement of the seventh lifting wheel 33 and the eighth lifting wheel 34 touching the first step wall is repeated. When the fifth lifting wheel 31 and the sixth lifting wheel 32 or the third lifting wheel 29 and the fourth lifting wheel 30 or the first lifting wheel 27 and the second lifting wheel 28 touch the step wall, the mechanical movement of the fifth lifting wheel 31 and the sixth lifting wheel 32 touching the first step wall is repeated, thereby realizing the automatic ascending of the wheelchair.

In this embodiment, the process of going downstairs is described as an example: when going downstairs, the downstairs button 43 is pressed, and then the upper half lifting rods 19 and the lower half lifting rods 23 of all the lifting wheel devices 5 are extended from the two ends of the lifting rod sleeve 20 at the same time, and at the same time, the lifting wheel retracting shaft 22 of the lifting wheel control frame 21 starts to rotate to lower the lifting wheels until the eight lifting wheel devices 5 reach the same horizontal plane and support the wheelchair, so that the wheelchair main box 3 and other devices are raised by 10 cm above the plane. When the wheelchair moves to the first step, it will move slowly. When the pressure sensors of the lifting wheels of the lifting wheels 1 27 and the lifting wheels 2 28 sense that there is no support below, the upper half lifting rod 19 and the lower half lifting rod 23 of the lifting wheels 1 27 and the lifting wheels 2 28 will simultaneously rise out of the lifting rod sleeve 20, so that the lifting wheels 1 27 and the lifting wheels 2 28 will descend until they are tangent to the first step surface of the downstairs. Then the lifting wheels 1 27 and the lifting wheels 2 28 will stop descending, and then the wheelchair will continue to move slowly. Similarly, when the pressure sensors of the lifting wheels 5 31 and the lifting wheels 6 32 or the lifting wheels 3 29 and the lifting wheels 4 30 or the lifting wheels 1 27 and the lifting wheels 2 28 sense that there is no support below, the mechanical movement of the lifting wheels 1 27 and the lifting wheels 2 28 when they descend the first step will be repeated. When the lifting wheels 7 33 and the lifting wheels 8 34 are descending the first step, the mechanical movement of the lifting wheels 1 27 and the lifting wheels 2 28 when they descend the first step will be repeated. When the lifting wheel 7 33 and the lifting wheel 8 34 are going down the next step, when the pressure sensor senses that there is no support below, the upper half lifting rod 19 and the lower half lifting rod 23 of the other six lifting wheel devices 5 except the lowering wheel 7 and the lifting wheel 8 34 are simultaneously retracted into the lifting rod sleeve 20, so that the wheelchair main body box 3 and other devices are lowered together with the lifting wheel 7 33 and the lifting wheel 8 34 until they are tangent to the next step surface. According to this rule, the process of the wheelchair automatically going upstairs is realized.
