10, ultrasonic sensor can be used in range sensor 70, is mainly used for incuding clean robot 100 at a distance of barrier or to be cleaned
The distance of step such as turns to or climbs step to make corresponding reaction.
Clean robot 100 climbs the step of step are as follows:
As shown in Fig. 8 to 16, it is followed successively by the schematic diagram of step 1 to 9；
Step 1: assuming that clean robot 100 at this time in first step, is intended to climb to second step, first leg 50 is located at
Close to the position of second step, the second supporting leg 60 is located remotely from the position of second step, starts clean robot 100；
Step 2: the first lifting assembly 51 and the second lifting assembly 61 act, and the first stepper motor 512 is along the first screw rod
513 move toward the direction close to the first connecting plate 52, and second stepper motor 612 is along the second screw rod 613 toward close to the second connection
The direction of plate 62 moves, while chassis 10 is raised to the height higher than second step；
Step 3: first servo motor 552 and/or the second servo motor 652 starting, drive the first moving wheel 556 and/or
The movement of second moving wheel 656, drives clean robot 100 to move toward the direction close to second step, and chassis 10 is close to front position
Part take to second step, range sensor 70 incudes first leg 50 at a distance of the distance between second step, to preset away from
From when, first servo motor 552 and/or 652 stopping of the second servo motor movement；
Step 4: the movement of the first stepper motor 512 moves the first screw rod 513 relative to the first stepper motor 512, by the
One moving parts 55 improve, and are equivalent to and lift first leg 50；
Step 5: the movement of the second moving parts 65 moves toward the direction of second step, takes first leg 50 to second
Rank, and the chassis 10 of majority is located at second step, second supporting leg of the induction of range sensor 70 60 at a distance of second step away from
From, until when pre-determined distance, 65 stopping of the second moving parts movement；
Step 6: second stepper motor 612 acts, and moves the second screw rod 613 relative to second stepper motor 612, by the
Two moving parts 65 improve, and are equivalent to and lift the second supporting leg 60；
Step 7: the movement of the first moving parts 55, the direction movement in orientation, takes the second supporting leg 60 to second step forward,
Clean robot 100 completes one step of climbing；
Step 8: walking driver 31 acts, and makes omni-directional wheel 33 along second step transverse movement, and drive chassis 10
12 transverse movement of universal wheel laterally cleans second step；
Step 9: swept away second step, turned in corner, walking driver 31 stops, the first moving parts 55 and/
Or second moving parts 65 drive omni-directional wheel 33 toward the direction of rotation of the first accessory whorl 35 and the second accessory whorl 36 move, complete corner
It turns to, when continuing to climb step, keeps first leg 50 in front, climbing sequence of second supporting leg 60 at rear.
The operation of the recyclable above-mentioned steps 2 to 9 of the climbing of multiple steps.
Clean robot 100 of the present invention can connect when in use to be equipped with inside external power supply or clean robot 100
Power storage cell, wherein inside sets power storage cell and can move in a big way, not by the length limitation of electric power connection line.
The switching of multiple directions of motion may be implemented in clean robot 100 of the present invention, in handoff procedure clean robot without
It need to turn round with converting motion direction, save space, can be turned to transverse movement and at narrow space corner, and climb
It is orderly smooth to climb step, can effectively clean at stair.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
One embodiment of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
