And, the telescopic rod of the travelling wheel electric push rod 91 is retracted, so as to drive the travelling wheel turning arm 92 to turn upwards, and further drive the travelling wheel axle 42 to turn upwards, thereby driving the travelling wheel 41 to turn upwards and be higher than the travelling crawler mechanism 3; in addition, the telescopic rod of the universal wheel electric push rod 101 is retracted, so that the universal wheel turning arm 102 is driven to turn upwards, and the universal wheel installation seat connecting rod 53 is driven to turn upwards, so that the universal wheel 51 is driven to turn upwards and be higher than the travelling crawler mechanism 3.
At the same time, the traveling crawler power assembly 11 is switched to transmit power.
Specifically, the telescopic rod of the clutch electric push rod 73 extends, and the clutch slider 71 is pushed by the shift rod 72 to move outwards along the output shaft of the motor 6 until the clutch slider 71 is matched with the concave-convex groove teeth 16 on the track sprocket 112, that is, the clutch slider 71 is closely matched with the track sprocket 112.
At this time, the motor 6 is operated, and the generated power is sequentially transmitted to the track driving pulley 34 through the clutch shoe 71, the track sprocket 112 and the track driving sprocket 111, so that the track 33 is driven to run, so that the track 33 is driven to travel along the ground at a slow speed.
2. The working mode of climbing stairs specifically comprises the following steps:
(1) When the stair climbing is prepared, firstly, a control rod or a control button on a vehicle body handrail is operated to control the extension rod of the track live push rod 81 to extend, the track overturning arm 82 is driven to overturn downwards, and then the track balancing rod 83 is driven to overturn downwards, so that the track 33 is driven to overturn downwards and flatten, and then the ground is attached. And, the telescopic rod of the travelling wheel electric push rod 91 is controlled to retract, the travelling wheel turning arm 92 is driven to turn upwards, and the travelling wheel axle 42 is driven to turn upwards, so that the travelling wheel 41 is driven to turn upwards and be higher than the travelling crawler mechanism 3; in addition, the telescopic rod of the universal wheel electric push rod 101 is controlled to retract, the universal wheel turning arm 102 is driven to turn upwards, and the universal wheel installation seat connecting rod 53 is driven to turn upwards, so that the universal wheel 51 is driven to turn upwards and be higher than the travelling crawler mechanism 3.
Then, the control lever or the control button is operated to control the extension rod of the clutch electric push rod 73 to extend, and the clutch slide block 71 is pushed by the deflector rod 72 to move outwards along the output shaft of the motor 6 until the clutch slide block 71 is matched with the concave-convex groove teeth 16 on the track sprocket 112, that is, the clutch slide block 71 is closely matched with the track sprocket 112.
Then, the control lever or the control button is operated to control the motor 6 to work, and the generated power is transmitted to the crawler belt driving pulley 34 through the clutch slider 71, the crawler belt sprocket 112 and the crawler belt driving sprocket 111 in sequence to drive the crawler belt 33 to run, so that the crawler belt 33 walks along the ground at a slower speed.
(2) When the distance measuring sensor 13 detects that a step exists, the control unit sends out a control instruction, the telescopic rod of the crawler electric push rod 81 retracts, the crawler overturning arm 82 is driven to overturn upwards, the crawler balancing rod 83 is driven to overturn upwards, and the travelling crawler mechanism 3 is driven to overturn upwards to be lifted.
At the same time, the motor 6 continues to drive the track 33 to run, and the track 33 on the upper side contacts the lobe of the first step and climbs upward.
(3) After the upper track 33 climbs the first step, the travelling crawler mechanism 3 is kept in a lifting state, and the motor 6 is kept to drive the track 33 to run until the upper track 33 contacts the convex angle of the second step, and the lower track 33 still contacts the ground below the stairs. At this time, the vehicle body safely passes over the convex corner of the step.
(4) When the upper crawler 33 continues to climb upwards and the lower crawler 33 contacts the first stage of step, the distance measuring sensor 13 cannot detect the step, the control unit sends a control instruction, the telescopic rod of the crawler electric push rod 81 stretches out to drive the crawler overturning arm 82 to overturn downwards so as to drive the crawler balance rod 83 to overturn downwards, the crawler 33 is driven to overturn downwards and flatten, and after the crawler 33 is flattened, the whole length of the crawler is longer, at least 4-5 steps can be contacted, so that the acting point can be obviously increased, the electric stair climbing walker is more stable in the stair climbing process, no left and right shaking occurs, the potential safety hazard is avoided, and the requirements of special groups such as the elderly, the disabled and the like for going upstairs and going normally are met.
During this process, the holding motor 6 continues to drive the track 33.
(5) When the upper crawler belt 33 climbs up the landing of the stair top, the traveling crawler mechanism 3 is kept in the flattened state, and at the same time, the motor 6 is kept to drive the crawler belt 33 continuously. At this time, the vehicle body safely passes over the convex corner of the step.
(6) When the vehicle body integrally climbs up the platform at the top of the stairs, that is, the upper and lower tracks 33 climb up the platform at the top of the stairs, the traveling crawler mechanism 3 is kept in a flattened state, and at the same time, the motor 6 is kept to drive the tracks 33 continuously. At this time, the traveling crawler 3 travels at a slower speed along the ground of the landing at the top of the stairs.
It should be noted that the present invention is also applicable to descending along stairs, and the principle is the same as above, and is not described herein.
