Description
TECHNICAL FIELD
[0001] The invention relates to the technical field of cleaner
robots, and more particularly to a lifting device for a mopping
roller of a cleaner robot.
DESCRIPTION OF RELATED ART
[0002] At present, mopping rags of most of cleaner robots on the
market each are fixed on the bottom of the robot in an
externally-mounted manner. Because of the externally-mounted
manner, there are mainly the following disadvantages that: 1). the
rag cannot be automatically cleaned and needs to be removed for
cleaning frequently during a process of floor mopping; and 2). the
rag is fixed on the bottom of the robot and cannot be lifted, and
the rag needs to be close to the floor in order to achieve cleaning
effect.
[0003] In this way, the cleaner robot will not be able to cross
obstacles. Now the general home environment requires the cleaner
robot to be able to cross the obstacle with at least 15 mm high or
a step with 15 mm high. But because the rag is fixed on the bottom
of the robot and close to the floor, the mopping rags of the
cleaner robots on the market cannot cross such obstacles.
[0004] However, the actual home environment will have a variety of
small steps, such as small carpets, wire raceways, floor decoration
corners and other obstacles. Now the mopping rag installed on the
cleaner robot on the market cannot cross the obstacles, or the
robot will be stuck because of the obstacles, which seriously
affects user's experience of the cleaner robot and seriously
affects normal operations of intelligent robots in the actual home
environment.
[0005] Moreover, since the mopping rag on the cleaner robot is
fixed and close to the floor, if the rag is wet, it will damage the
floor if the rag contacts the ground or wood floor for a long
time.
[0006] A Chinese patent application No. 201110007817.8 (with a
publication No. CN102578958A), filed on Jan. 5, 2011, published on
Jul. 18, 2012 and entitled "robot with a workpiece lifting device",
discloses a robot with a workpiece lifting device. The robot with a
workpiece lifting device includes a robot body and the workpiece
lifting device disposed inside the robot body. The workpiece
lifting device includes a workpiece and a lifting drive assembly.
The lifting drive assembly includes a drive motor and a rotator
connected to a drive shaft of the drive motor, the rotator is
provided with a bevel cam, and a fixing frame is arranged above the
workpiece and movably connected inside the robot body. A top end of
the fixing frame abuts against an inclined surface on a lower side
of the bevel cam. The robot with the workpiece lifting device as
disclosed is simple in structure, convenient in operation and high
in working efficiency, and can be used for effectively cleaning a
glass to-be-cleaned.
[0007] The above patent document discloses a robot with a workpiece
lifting device, however the robot with a workpiece lifting device
still has a relatively complex structure, is not flexible enough to
use, the control of lifting is not accurate and the lifting
automation is not high.

[0035] The invention provides a lifting device for a mopping roller
of a cleaner robot.
[0036] Referring to FIG. 1 through FIG. 8, in an embodiment of the
invention, as to the lifting device for a mopping roller of a
cleaner robot, the cleaner robot includes a robot body 1, and the
robot body 1 is disposed with a cleaning device 8. The cleaning
device 8 includes the mopping roller 7. The mopping roller 7 is
disposed with a rag. The lifting device 2 is disposed inside the
robot body 1. The lifting device 2 includes a driving mechanism,
and the driving mechanism is connected with the cleaning device
8.
[0037] The robot body 1 is provided with a roller-support frame 81,
and the cleaning device 8 is disposed on the roller-support frame
81.
[0038] In the embodiment, preferably, the driving mechanism
includes a slider 3.
[0039] In the embodiment, further and preferably, the slider 3 is a
made of a metal material. That is, the driving mechanism includes a
metal slider 3.
[0040] In the embodiment, preferably, the driving mechanism may
include a drive motor, a fixing frame, a screw rod and the metal
slider 3.
[0041] In the embodiment, the cleaning device 8 is installed on the
roller-support frame 81, and preferably, two sides of the
roller-support frame 81 are provided with rotation shafts 4
respectively, a base 9 is disposed below the roller-support frame
81, and the base 9 is connected with the roller-support frame 81 by
the rotation shafts 4.
[0042] Furthermore, preferably, the roller-support frame 81 is made
of a plastic material.
[0043] The cleaning device 8 of the invention can realize the
lifting and lowering of the mopping roller 7 or the rag on the
mopping roller 7, under the control of the lifting device 2.
[0044] At present, under the action of the lifting device, it can
realize the lifting and lowering of the rag of the mopping roller.
When a floor mopping is required, the rag can be lowered and close
to the floor under the control of the host software to realize
floor mopping, and when there is no need of floor mopping, under
the control of the host software, the mopping roller is lifted up
and leaves the floor/ground.
[0045] In the embodiment, the cleaning device 8 of the invention is
hung on the roller-support frame 81, and thus the lifting device 2
can lift up the mopping roller 7 based on the roller-support frame
81.
[0046] Since the cleaning device 8 is disposed on the
roller-support frame 81 in a non-fixed way (i.e., in a movable
way), when being lifted up by an external force, the cleaning
device 8 can be lifted without the control of software and other
mechanisms, which makes it easier for the actual operation of the
invention to randomly deal with problems such as crossing obstacles
or steps. The cleaning device 8 can automatically rise when
encountering obstacles on the floor, during a process of floor
cleaning.
[0047] In the embodiment, the cleaning device 8 is provided with a
bump 31, the driving mechanism or the metal slider 3 is configured
(i.e., structured and arranged) to control lifting and lowering of
the cleaning device 8 by the bump 31.
[0048] The configuration of the bump 31 makes the connection
between the lifting device 2 and the cleaning device 8 is more
firmly, and the lifting control of the cleaning device 8 is more
effective.
[0049] Moreover, preferably, the bump 31 is disposed at a middle
position of an edge of the cleaning device 8.
[0050] As shown in FIG. 5, FIG. 5 shows a state of the lifting
device 2 is not working, the slider 3 is at a lowest position, the
mopping roller 7 of the cleaning device 8 is in free contact with
the floor 6, and at this time, the cleaning device 8 is in a
working state or a ready working state.
[0051] As shown in FIG. 6, FIG. 6 shows the slider 3 of the lifting
device 2 is lifted up, the cleaning device 8 is lifted up
correspondingly, so that the mopping roller 7 of the cleaning
device 8 leaves the floor 6 to a suitable height and stops
working.
[0052] In another embodiment of the invention, two sides of the
cleaning device 8 are provided with springs 5 respectively, one end
(first end) of each of the springs 5 is connected to the cleaning
device 8, and the other end (second end opposite to the first end)
of each of the springs 5 is connected to the robot body 1.
[0053] Preferably, the robot body 1 is provided with spring
limiting mechanisms (may also be referred to as spring limiters)
51, and the other ends (second ends) of the springs 5 are connected
with the spring limiting mechanisms 51 respectively.
[0054] In the embodiment, during the cleaning device 8 cleans a
floor, a friction force applied from the cleaning device 8 onto the
floor 6 is resulting from a downward force generated by the springs
5 on the two sides of the cleaning device 8, i.e., the springs 5
make the mopping roller 7 have a certain friction force against the
floor 6, so as to achieve the improved effect of floor mopping.
[0055] In the embodiment, FIG. 7 is a schematic state view of the
cleaning device 8 being not lifted up, and FIG. 8 is a schematic
state view of the cleaning device 8 been lifted up.
[0056] The above are only preferred embodiments of the invention,
and does not limit the patent protection scope of the invention. On
the premise of not departing from the spirit and scope of the
invention, the invention will have various modification and
improvements. Under the inventive concept of the invention,
equivalent structural transformations made by using the description
and the attached drawings of the invention, or direct/indirect
application in other related technical fields are all included in
the scope of patent protection of the invention.
