The working principle of the cleaning robot in this embodiment is as follows:
when the cleaning robot is in a non-mopping state, as shown in fig. 3 and 19, the mopping mechanism 100 is located at the initial position, the first mopping assembly 110 and the second mopping assembly 120 are staggered, the projection of the first mopping assembly in the vertical direction partially overlaps the projection of the second mopping assembly in the vertical direction, and the third motor 161 and the fourth motor 171 are not operated.
The steps of the cleaning robot entering the mopping state from the non-mopping state are as follows:
s01, controlling the output shaft of the fifth motor 211 to rotate, wherein the output shaft of the fifth motor 211 drives the cam to rotate, the cam drives the sheeting and mopping mechanism 100 to move downwards after rotating, and when the fifth motor 211 drives the cam to rotate by 90 degrees, the sheeting and mopping mechanism 100 descends to the middle position as shown in FIG. 19;
and S02, controlling the output shafts of the first motor 131 and the second motor 141 to rotate after the fifth motor 211 drives the cam to rotate for 90 degrees, and continuing to rotate the output shaft of the fifth motor 211 at the moment (the fifth motor 211 drives the cam to rotate for 180 degrees totally and then stops working). An output shaft of the first motor 131 drives the first gear 133 to rotate clockwise (in fig. 8) through the first transmission case 132, and drives the first mopping assembly 110 to move relative to the robot body 300 through the engagement between the first gear 133 and the first rack 163, so that the projection of the first mopping assembly 110 in the vertical direction deviates from the projection of the robot body in the vertical direction; an output shaft of the second motor 141 drives the second gear 143 to rotate counterclockwise (in fig. 8) through the second transmission case 142, and drives the fifth driving assembly 170 and the second mopping assembly 120 to move relative to the robot body 300 through the engagement between the second gear 143 and the second rack 173, so that the projection of the second mopping assembly 120 in the vertical direction deviates from the projection of the robot body in the vertical direction;
s03, controlling the first motor 131 and the second motor 141 to stop working after the first motor 131 and the second motor 141 work for a preset time, wherein the preset time may be 2S in this embodiment; at this time, the first mopping assembly 110 and the second mopping assembly 120 move to the position shown in fig. 2 relative to the robot body 300, and at this time, the first mopping assembly 110, the second mopping assembly 120, the second driving assembly 160 and the fifth driving assembly 170 move to the position shown in fig. 8 and 21 relative to the robot body 300; at the moment, the projection of the first mopping assembly along the vertical direction is not overlapped with the projection of the second mopping assembly along the vertical direction;
and S04, after the cam is driven by the fifth motor 211 to rotate by 180 degrees totally, the fifth motor 211 stops working, and the cam rotates to drive the tabletting and mopping mechanism 100 to move downwards to the lowest position. Before the floor mopping mechanism 100 descends, the first floor mopping assembly 110 is lower than the second floor mopping assembly 120, so that the first floor mopping assembly 110 contacts with the ground firstly during the descending process of the floor mopping mechanism 100, the first floor mopping assembly 110 contacts with the ground, the first floor mopping assembly 110 cannot move downwards any more, the first floor mopping assembly 110 presses the driving spring 150 to compress the driving spring 150, then the second floor mopping assembly 120 continues to move downwards, and the floor mopping mechanism 100 moves to the lowest position when the second floor mopping assembly 120 also contacts with the ground; the state of the cleaning robot at this time is as shown in fig. 1, fig. 2, fig. 8, fig. 15, fig. 16, and fig. 22;
s05, the third motor 161 drives the first floor mopping assembly 110 to rotate, the fourth motor 171 drives the second floor mopping assembly 120 to rotate, and the cleaning robot enters a floor mopping state.
The steps of the cleaning robot entering the non-mopping state from the mopping state are as follows:
s11, controlling the third motor 161 and the fourth motor 171 to stop working, so that the first mopping assembly 110 and the second mopping assembly 120 do not rotate any more, and at this time, the cleaning robot is as shown in fig. 22;
s12, the output shafts of the fifth motor 211, the first motor 131 and the second motor 141 are controlled to rotate (the rotation direction of the output shaft of the first motor 131 in step S12 is opposite to the rotation direction of the output shaft of the first motor 131 in step S02, and the rotation direction of the output shaft of the second motor 141 in step S12 is opposite to the rotation direction of the output shaft of the second motor 141 in step S02), and after the fifth motor 211 drives the cam to rotate, each return spring pushes the tablet and floor mopping mechanism 100 to move upwards. An output shaft of the first motor 131 drives the first gear 133 to rotate counterclockwise (in fig. 12) through the first transmission case 132, and drives the first mopping assembly 110 to move relative to the robot body 300 through the engagement between the first gear 133 and the first rack 163, so that the projection of the first mopping assembly 110 in the vertical direction moves to the projection of the robot body in the vertical direction; an output shaft of the second motor 141 drives the second gear 143 to rotate clockwise (in fig. 12) through the second transmission case 142, and drives the fifth driving assembly 170 and the second mopping assembly 120 to move relative to the robot body 300 through the engagement between the second gear 143 and the second rack 173, so that the projection of the second mopping assembly 120 along the vertical direction moves to the projection of the robot body along the vertical direction;
s13, when the fifth motor 211 drives the cam to rotate 90 degrees, the return spring pushes the sheeting and mopping mechanism 100 to rise to the middle position as shown in FIG. 21; before the floor mopping mechanism 100 is lifted, the first floor mopping assembly 110 is vertically flush with the second floor mopping assembly 120, and the driving spring 150 is compressed by the first floor mopping assembly 110, so that the driving spring 150 which is originally compressed in the process of lifting the floor mopping mechanism 100 is gradually extended, and the extended driving spring 150 pushes the first floor mopping assembly 110 to descend, so that the first floor mopping assembly 110 can vertically move downwards relative to the second floor mopping assembly 120, so that the first floor mopping assembly 110 is vertically misaligned with the second floor mopping assembly 120 as shown in fig. 21, and at this time, the output shaft of the fifth motor 211 continues to rotate (the fifth motor 211 drives the cam to rotate by 180 degrees in total and then stops working);
s14, controlling the first motor 131 and the second motor 141 to stop working after the first motor 131 and the second motor 141 work for a preset time, wherein the first mopping assembly 110 and the second mopping assembly 120 move to the positions shown in fig. 20 relative to the robot body 300, and the projection of the first mopping assembly in the vertical direction is partially overlapped with the projection of the second mopping assembly in the vertical direction;
s15, when the fifth motor 211 drives the cam to rotate 180 ° in total and then the fifth motor 211 stops working, the return spring pushes the sheeting and mopping mechanism 100 to rise to the initial position as shown in fig. 6, and the mopping mechanism 100 on the cleaning robot is shown in fig. 3 and 19.
As can be seen from comparing fig. 2 and 3, the floor space of the cleaning robot in fig. 3 is smaller than that of the cleaning robot in fig. 2, so that it is convenient for a user to store the cleaning robot.
