The cleaning robot brings great convenience to the life of people, liberates the hands of people and is more and more favored by people. However, the existing cleaning robot has the condition that the height of the floor mopping module cannot be recorded, and user experience is influenced.
In view of this, the present invention provides a cleaning robot, and aims to solve the technical problem that the cleaning robot in the prior art affects user experience due to the fact that the height of a floor mopping module cannot be recorded. Please refer to fig. 1 and fig. 2, which illustrate an embodiment of a cleaning robot according to the present invention.
Referring to fig. 1 and 2, a cleaning robot 100 according to the present invention includes a base 1, an executing portion 2, a lifting mechanism 3, and a detecting and positioning device 4, wherein the executing portion 2 is used to connect a cleaning member 6; the lifting mechanism 3 is connected with the base 1 and the executing part 2 and is used for driving the executing part 2 to move up and down relative to the base 1; the detection positioning device 4 is used for detecting the position of the cleaning piece 6 and positioning the lifting mechanism 3. In the scheme, the lifting mechanism 3 drives the executing part 2 to move, so that the cleaning piece moves up and down relative to the base 1, and when the cleaning piece moves to the original position, the cleaning piece stops at the original position through positioning, so that the problem that the cleaning robot 100 cannot record the height of the cleaning piece to influence user experience is avoided.
It should be noted that, in this embodiment, the cleaning member 6 is a mop. Further, the up-down direction in the present application is the up-down positional relationship between the respective components of the cleaning robot 100 in normal operation, and if the specific attitude is changed, the directional indication is changed accordingly.
In addition, the origin position may be a position where the cleaning member 6 moves away from the base 1, or may be other specific positions, which is not limited herein. In the present embodiment, the origin position is a position where the cleaning member 6 moves to be close to the base 1, that is, a highest point to which the cleaning member 6 can move.
Meanwhile, in an embodiment, after the cleaning member 6 stops at the original position, the driving direction of the lifting mechanism 3 may be switched, and the executing portion 2 is driven to move in a direction opposite to the previous moving direction.
Further, in an embodiment, the detecting and positioning device 4 is a sensor, and the cleaning robot 100 further includes a control device electrically connected to the lifting mechanism 3 and the sensor.
Furthermore, in order to improve the integration of the cleaning robot 100 to achieve the effect of reducing the volume, the sensor is a touch sensor 41 disposed on the moving stroke of the implement part 2, and the touch sensor 41 is electrically connected to the control device. In this embodiment, the contact sensor 41 is located on the moving stroke of the actuator 2, and is configured to contact with the actuator 2, so that the cleaning member stops at the original position. Since the actuator 2 must be movably installed, a space corresponding to a moving stroke of the actuator 2 needs to be installed to avoid interference with the actuator 2 when designing the cleaning robot 100. Therefore, when the contact sensor 41 is disposed on the moving stroke of the executing part 2, another corresponding space is not required to be disposed for disposing the contact sensor 41, so as to reduce the size of the cleaning robot 100, and further, the cleaning of a relatively narrow space is facilitated, thereby eliminating dead angles.
It should be noted that the control device is a circuit board assembly, and the circuit board assembly is electrically connected to the lifting mechanism 3 and the touch sensor 41, so that when the executing portion 2 contacts the touch sensor 41, the circuit board assembly can respond quickly and control the lifting mechanism 3 to stop moving, so that the cleaning member stops at the origin position.
It can be understood that the circuit board assembly is in the prior art, and the touch sensor 41 and the lifting mechanism 3 may be controlled, which is not described herein again. The form of arrangement of the touch sensor 41 is not limited, and may be a micro switch type sensor, or may be another form of touch sensor 41.
In another embodiment, the sensor comprises a photoelectric sensor formed with a light path extending horizontally and over the active travel of the implement portion 2. The position of the actuator 2 is detected by the photoelectric sensor. Specifically, when the executing part 2 is located at a position close to the base 1, the optical path of the photoelectric sensor is blocked, and the photoelectric sensor makes feedback after detecting a corresponding signal.
Because the driving shaft of a power source like a driving motor is blocked in the normal working process, the output current of the driving motor or the like measuring power output intensity index parameter can fluctuate greatly. In one embodiment, the lifting mechanism 3 includes a lifting driving component and a lifting executing component, the lifting executing component is connected with the base 1 and the executing part 2, the lifting driving component is used for providing power for the lifting mechanism 3, and at least one motion parameter of the lifting driving component can be obtained; the detection positioning device 4 is arranged on the stroke of the lifting execution component or the execution part 2 and is used for providing resistance when contacting with the lifting execution component.
Specifically, in this embodiment, the setting form of the detection positioning device 4 is not limited, and may be a form of a limiting block, the limiting block is disposed on one side of the base 1 close to the executing portion 2, and when the cleaning member 6 moves to the original point position, the limiting block is located between the executing portion 2 and the base 1 to limit the executing portion 2 to continue moving upward, so as to block the movement of the lifting driving assembly, and further change the corresponding movement parameter of the lifting driving assembly.
The detection positioning device 4 can also be a compression spring which is arranged on one side of the base 1 close to the executing part 2, and when the cleaning piece 6 is located at the original position, the compression spring is compressed at the limit position so as to limit the executing part 2 to move upwards continuously. The detection and positioning device 4 can also be in other forms.
The scheme utilizes the characteristic of a power source such as a driving motor and the like to judge the original position of the cleaning piece 6. When the actuator 2 moves to a position close to the base 1, the detection positioning device 4 prevents the lift actuator from moving so that the corresponding parameters of the lift drive assembly, such as current, fluctuate significantly.
It will be appreciated that a sensing mechanism may also be provided in this embodiment to sense fluctuations in the current to the lift drive assembly and make adjustments accordingly. Specifically, in this scheme, the detection device is the control device. Therefore, after the control device acquires the corresponding parameters output by the lifting driving assembly, the lifting driving assembly is controlled to stop driving, so that the cleaning piece is temporarily stopped at the original point position.
The arrangement form of the lifting mechanism 3 is not limited, and the lifting mechanism can be in a gear and rack transmission mode, a belt and chain transmission mode or other forms. In this embodiment, the lifting mechanism 3 includes a lifting driving component and a lifting executing component, the lifting executing component is connected to the base 1 and the executing part 2, and the lifting driving component is used for providing power for the lifting mechanism 3; the lifting executing assembly comprises a screw rod 31, a nut and a guide mechanism, the executing part 2 moves on the base 1 along the guide mechanism, the screw rod 31 is rotatably arranged on the base 1, the nut is arranged on the executing part 2, and the screw rod 31 is meshed with the nut; the lifting drive assembly is connected to the lead screw 31. The scheme is that the screw rod 31 is matched with the screw nut to realize that the cleaning piece 6 moves up and down, the structure is simple and reliable, and the cost is saved.
Furthermore, in order to increase the moving space of the cleaning member 6, a transmission shaft 21 is convexly arranged on the executing part 2 in the direction away from the base 1, and one end of the transmission shaft 21 away from the executing part 2 is used for connecting the cleaning member 6. According to the scheme, the cleaning piece 6 extends out of the shell of the cleaning robot 100 through the transmission shaft 21, so that the cleaning piece 6 can move conveniently.
Further, in order to avoid the position of the executing part 2 from shifting when moving in the up-down direction, in this embodiment, the guiding mechanism includes a guiding shaft 34 disposed on the base 1, the guiding shaft 34 extends in the up-down direction, and the executing part 2 is provided with a guiding hole for sliding along the guiding shaft 34. The accuracy of the moving stroke of the executing part 2 is improved by matching the guide hole with the executing part 2, and meanwhile, the executing part 2 can move up and down on the screw rod 31 conveniently, so that the movement of the cleaning piece 6 is smoother and more stable.
Further, the specific driving arrangement of the lifting mechanism 3 is not limited. In an embodiment, the lifting mechanism 3 includes a brush motor 32 and an encoder 33, the brush motor 32 drives the executing portion 2 to move, and the encoder 33 is configured to obtain a rotation angle of a driving shaft of the brush motor 32.
It is understood that the encoder 33 may be a magnetic encoder or a grating encoder, and is not limited thereto. The encoder 33 may also record the corresponding power pattern output by the brush motor 32.
In another embodiment, the lifting mechanism 3 includes a stepping motor, and the driving portion is formed at the stepping motor. The embodiment records the output rotation angle, rotation speed and the like by utilizing the pulse counting characteristic of the stepping motor.
In another embodiment, the lifting mechanism 3 includes a brushless motor driving the actuator 2 to move, and a hall sensor for acquiring a rotation angle of a driving shaft of the brushless motor. The embodiment can also record the rotating speed output by the brushless motor by utilizing the Hall sensor.
