Fig. 2 is a side view of a scraping device 100 provided in an embodiment of the present application. Fig. 3 is a bottom view of the scraping device 100 provided in the embodiments of the present application. Fig. 4 is a schematic view of a use state of the scraping apparatus 100 according to the embodiment of the present application. Fig. 5 is an exploded view of the scraping device 100 provided in the embodiments of the present application. Fig. 6 is an exploded view of a portion of the wiper device 100 according to an embodiment of the present disclosure.

As shown in fig. 1 to 6, a scraping apparatus 100 according to an embodiment of the present application includes: a base 10, a double scraper 20 (i.e. two scrapers 20), a friction member 30 and a transmission assembly 40.

Wherein, the double scraping elements 20 are respectively arranged at two opposite sides of the base 10, the friction element 30 is movably arranged on the outer surface 11 of the base 10, and the friction element 30 is in transmission connection with the double scraping elements 20 through the transmission assembly 40. The outer surface 11 of the base 10 is a surface of the base 10 abutting against the surface to be cleaned, or the outer surface 11 is a surface of the base 10 and the surface to be cleaned, which are attached to each other.

When the wiping device 100 is moved to wipe the surface to be cleaned, the friction member 30 is moved backward relative to the base 10 by the friction force with the surface to be cleaned, so that the friction member 30 drives the wiping member 20 located at the front side in the traveling direction away from the surface to be cleaned through the transmission assembly 40 to be inoperative, and drives the wiping member 20 located at the rear side in the traveling direction close to the surface to be cleaned to perform wiping work (e.g., wiping).

In the present embodiment, the scraping device 100 comprises two scraping elements 20, respectively arranged on two opposite sides of the base 10, for example on two opposite long sides of the base 10 in fig. 1-4. The friction member 30 is movably disposed on the outer surface 11 and is displaceable relative to the outer surface 11. In use, the friction member 30 can rub against the surface to be cleaned to generate a friction force, and the generated friction force is large enough to enable the friction member 30 to move backward relative to the outer surface 11 (i.e. relative to the base 10) under the action of the friction force, and further drive the two scraping members 20 to move through the transmission assembly 40.

Specifically, the scraping device 100 includes a base 10 and a top cover 60, the top cover 60 further includes a top wall 61 and a side wall 62, the side wall 62 is disposed around the circumference of the top wall 61, the top cover 60 can be fixedly covered on the base 10 to form an accommodating cavity with a hollow interior, and the transmission assembly 40 is disposed in the accommodating cavity. The friction member 30 is in driving connection with the double scraping members 20 through the driving assembly 40, i.e. the friction member 30 can drive the two scraping members 20 to move through the driving assembly 40.

The present application is not limited to the specific form of the drive assembly 40. For example, any of a plurality of different parts (gears, racks, cams, eccentrics, sliders, belts, links, etc.), different connections (abutments, articulations, sliding connections, rack-and-pinion connections, belt connections, pin-and-slot connections, etc.) may be included to cooperate with each other to effect the transfer of the movement of the friction member 30 to the two scraping members 20 and thus the driving of the scraping members 20.

In the embodiment of the present application, the scraping device 100 moves to scrape the surface to be cleaned, which may be a user manually moves the scraping device 100 to scrape the surface to be cleaned, or an internal motor drives the scraping device 100 to move to scrape the surface to be cleaned, and this application is not limited thereto.

Optionally, in other embodiments, the scraping apparatus 100 further comprises a walking assembly including a walking motor, a walking wheel, and the like, so that the scraping apparatus 100 can automatically walk without manual driving.

Alternatively, in other embodiments, the scraping device 100 may be a glass cleaning robot, which, in addition to the above-mentioned walking assembly, also comprises sensors, intelligent control systems, etc., for example, which can plan the cleaning route.

In the present embodiment, the friction member 30 does not operate to drive the scraping member 20 located at the front side in the traveling direction away from the surface to be cleaned through the transmission assembly 40, and drives the scraping member 20 located at the rear side in the traveling direction close to the surface to be cleaned to perform the scraping operation.

The driving of the scraping element 20 away from the surface to be cleaned may be the driving of the scraping element 20 to retract into the scraping device 100, or may be performed in other manners, such as folding, pushing over the scraping element 20, etc., so that the front end of the scraping element 20 can be away from the surface to be cleaned, and thus the scraping element 20 can be disabled.

Accordingly, the driving of the scraping member 20 close to the surface to be cleaned for the scraping operation may be to drive the scraping member 20 to protrude toward the surface to be cleaned, or may be to drive the scraping member 20 in another form, such as to raise (straighten) the scraping member 20, etc., so that the front end of the scraping member 20 is close to (e.g., in abutment with) the surface to be cleaned, thereby enabling the scraping operation. The present application does not limit the operation of the scraper 20, as long as the scraper 20 can be switched between operating and non-operating.

As shown in fig. 2-4, in the present embodiment, a wipe 90 is also fixedly disposed on the outer surface 11 of the base 10 for better wiping of the surface to be cleaned. For example, the wipe 90 may be a wipe or sponge or the like. The wipes 90 may be in two pieces, oppositely disposed on opposite sides of the base 10.

Further, as shown in fig. 2, the friction member 30 is disposed in the wipe 90, and the friction member 30 protrudes from the wiping surface of the wipe 90, so that the friction member 30 can better perform a relative friction with the surface to be cleaned.

As shown in fig. 5, the outer surface 11 of the base 10 may be formed in a stepped shape with a center protruding from opposite sides thereof, so that the wiping surface of the wiper 90 may be flush with the outer surface 11 of the middle portion of the base 10 after the wiper 90 is fixed to the outer surfaces 11 of the sides, thereby facilitating wiping by a user.

As shown in fig. 2, in the free state, the front end portions of the two scraping members 20 on the left and right sides may be slightly higher than the wiping surface of the wiper 90, thereby reserving a certain movement space for the scraping members 20. As shown in fig. 4, when the scraping apparatus 100 moves in the direction B (i.e. right side in the figure) to scrape the surface to be cleaned (not shown in the figure), the friction member 30 is subjected to a friction force to move backward (i.e. to move leftward) relative to the base 10, the transmission assembly 40 inside the scraping apparatus 100 further drives the front scraping member 20 (i.e. the right scraping member 20) to be retracted away from the surface to be cleaned, and does not perform a scraping operation, and drives the rear scraping member 20 (i.e. the left scraping member 20) to be extended close to the surface to be cleaned (at this time, the front end of the rear scraping member 20 can abut against the surface to be cleaned) to perform a scraping operation.

In the embodiment of the present application, the scraping device 100 may be used to scrape and clean a surface such as a glass surface, a desktop, a wall surface, a ground, a blackboard, and the like, that is, the surface to be cleaned may be any one of a glass surface, a desktop, a wall surface, a ground, a blackboard surface, and the like, which is not limited in this application.

As shown in fig. 1-5, the scraping apparatus 100 further comprises a mounting base 80, the scraping element 20 is fixed on the mounting base 80, and the transmission assembly 40 is in transmission connection with the scraping element 20 through the mounting base 80.

As shown in fig. 1-4, a gap is formed between the side wall 62 of the cap 60 and the base 10, which gap provides clearance for the scraping element 20 to move so that the scraping element 20 can move away from or closer to the surface to be cleaned.

The present application does not limit the specific structure of the scraper 20, and the scraper 20 may be any device capable of performing a scraping operation, such as a scraper bar, a scraper, a sweeper brush, or the like.

In the present embodiment, the scraping member 20 may be a scraping strip.

Optionally, the scraping strip may be made of plastic or rubber.

Alternatively, the wiper strip may be curved, with the middle opposite ends projecting away from the base 10 (i.e., the two opposing wiper strips now being "()" shaped), to better collect water.

Alternatively, the scraping members 20 of each side may be composed of a plurality of scraping bars (or scrapers, sweeping brushes, etc.). For example, the plurality of wiper strips may be consecutive or parallel to each other to constitute the wiper member 20.

The friction member 30 should have a sufficient coefficient of friction to generate sufficient friction, and the friction member 30 should also be wear resistant, soak resistant, and corrosion resistant. The present application is not limited to the specific form of the friction member 30. In the present embodiment, the friction member 30 is a friction block. For example, the friction block may be made of plastic, rubber, resin, metal, leather, or the like. The friction block can be made of different materials in a corresponding rotation mode according to different surfaces to be cleaned.

Preferably, the friction block may be made of leather, which may be animal leather or artificial leather. For example, the animal leather may be cow leather, sheep leather, donkey leather, or the like.

More preferably, the friction block is made of cowhide, which has a suitable friction coefficient, is cheap and easily available, and is wear-resistant, immersion-resistant, corrosion-resistant, and has a long service life.

It will be understood that the displacement of the friction member 30 with respect to the base 10 is limited and controllable, and in the present embodiment, the friction member 30 is moved quickly by the action of the friction force to the maximum displacement and is maintained at the maximum displacement, at which the two scraping members 20 are also brought to the preset position and are maintained at the preset position. In this preset position, one of the scraping members 20 is retracted and not operated, while the other scraping member 20 is extended to perform the scraping operation, and at this time, the scraping device 100 is integrally moved to make the rear scraping member 20 perform the scraping operation, and during the scraping operation, the friction member 30 is kept stationary relative to the base 10, and there is no relative movement therebetween, that is, the friction member 30 and the base 10 are relatively displaced only in the following two cases, namely, the first case is: when the scraping device 100 is attached to the surface to be cleaned to start the scraping action; the other situation is that: when the scraping device 100 is reversed, and in both cases, the relative displacement of the friction member 30 with respect to the base 10 occurs instantaneously and then remains in the above-mentioned preset position, remaining relatively still.

According to the scraping device 100 provided by the embodiment of the application, the friction member 30 disposed on the base 10 can rub against the surface to be cleaned to generate a friction force, when the scraping device 100 moves to the right, the friction member 30 moves to the left due to the friction force to the left, and can further drive the right scraping member 20 to be retracted and not work through the transmission assembly 40, and drive the left scraping member 20 to be extended to perform a scraping work. When the scraping device 100 is moved to the edge of the surface to be cleaned, without rotating the scraping device 100, the scraping device 100 can be directly controlled to move to the left, and at this time, under the action of the friction force, the friction member 30 drives the positions of the two scraping members 20 through the transmission assembly 40 to switch, that is, the scraping member 20 on the right side is extended to perform the scraping work, and the scraping member 20 on the left side is retracted to be out of work. The whole scraping process of the scraping device 100 provided by the embodiment of the application has continuity, the surface to be cleaned can be cleaned in a reciprocating mode like a blackboard, the operation is simpler and more convenient, the cleaning efficiency of a user can be improved, and dead angles cannot be formed on the surface to be cleaned, so that the cleaning effect is improved.

To describe the function of the scraping device 100 more fully, it is mentioned in the above description whether it is the front scraping element 20 or the rear scraping element 20; and whether the scraper 20 on the left side or the scraper 20 on the right side, the purpose is to illustrate two scraper 20 arranged oppositely, and in use, whether the scraper is moved forward and backward or moved left and right to perform a scraping operation, one scraper 20 of the two scrapers performs a scraping operation, and the other scraper 20 does not perform a scraping operation, which is not limited in the present application.

For ease of description and understanding, the scraping device 100 provided herein will be further described in the following description with a glass surface as the surface to be cleaned, that is, the scraping device 100 may be understood as a glass wiper hereinafter.

As shown in fig. 5 and 6, a connecting through hole 12 penetrating through the base 10 is formed in the base 10, and the transmission assembly 40 includes a connecting member 42 movably disposed in the connecting through hole 12 and a translation member 43 movably disposed in the base 10.

When the scraping device moves to scrape the surface to be cleaned, the friction member 30 drives the translation member 43 to move backwards relative to the base 10 in the traveling direction through the connecting member 42, the translation member 43 further drives the scraping member 20 at the front side of the traveling direction to be away from the surface to be cleaned and not to work, and drives the scraping member 20 at the rear side of the traveling direction to be close to the surface to be cleaned for scraping work.

That is, the friction member 30 drives the translation member 43 to move through the connecting member 42, and the translation member 43 is limited to move only in the horizontal direction and cannot move in the vertical direction. The translation member 43 is able to move backwards in the direction of travel with respect to the base 10, under the action of the friction member 30, the translation member 43 transmitting this movement further to the double scraping members 20, in turn bringing about the movement of the scraping members 20.

The specific form of the connecting member 42 is not limited in the present application, as long as the movement of the friction member 30 is transmitted to the translation member 43, and the translation member 43 is driven to translate.

Fig. 7 is a schematic cross-sectional view at AA in fig. 3. As shown in fig. 7, in the embodiment of the present application, the connecting member 42 includes a transmission belt 42a and two pulleys 42b, the two pulleys 42b are spaced apart and rotatably connected to the base 10, the transmission belt 42a is disposed around the two pulleys 42b, one side of the transmission belt 42a is fixedly connected to the friction member 30, and the other side is drivingly connected to the translation member 43.

Specifically, in the present embodiment, the transmission can be performed by the transmission belt 42a, in this case, a slot can be formed on the hole wall of the connecting through hole 12, the pulley 42b can be rotatably connected in the slot, the two pulleys 42b are disposed at an interval, and the transmission belt 42a is wrapped on the outer sides of the two pulleys 42 b. The two pulleys 42b have the same outer diameter, and the planes of the two rotation shafts should be parallel to the outer surface 11, so that the friction members 30 provided on the transmission belt 42a are also parallel to the outer surface 11.

When the friction member 30 moves backward under the action of the friction force, the transmission belt 42a is driven to rotate, and the translation member 43 is driven to move by the transmission belt 42 a.

The present application does not limit the transmission form of the transmission belt 42a and the translation member 43. In the embodiment of the present application, the driving belt 42a is in mesh transmission with the translation member 43.

At this time, a first saw-tooth structure 42c is provided on a side of the transmission belt 42a facing the translation member 43, a second saw-tooth structure 43a is provided on a side of the translation member 43 facing the transmission belt 42a, and the transmission belt 42a and the translation member 43 are in mesh transmission through the first saw-tooth structure 42c and the second saw-tooth structure 43 a.

Further, in order to perform better connection fixing of the transmission belt 42a, as shown in fig. 7, in the embodiment of the present application, the transmission belt 42a is a toothed belt, the pulley 42b is a serrated wheel, and the toothed belt and the serrated wheel are engaged with each other.

As shown in fig. 5 and 6, the transmission assembly 40 further includes a swinging member 41 hinged in the base 10, and the double scraping members 20 are respectively fixedly connected with two ends of the swinging member 41; the flat member 43 is in transmission connection with the swinging member 41, and when the scraping device 100 moves to scrape the surface to be cleaned, the flat member 43 drives one end of the swinging member 41 on the front side of the traveling direction to be away from the surface to be cleaned and drives one end on the rear side of the traveling direction to be close to the surface to be cleaned.

Specifically, the oscillating member 41 is hinged to the inner surface of the base 10 and can oscillate relative to the base 10, and two ends of the oscillating member 41 are respectively fixedly connected to the double scraping members 20, so that the oscillating member 41 can drive the double scraping members 20 to oscillate.

Thus, when the scraping device 100 moves rightward, the friction member 30 moves leftward due to the leftward friction force, and at this time, the friction member 30 can sequentially pass through the connecting member 42 and the sliding member 43 to drive the oscillating member 41 to oscillate, so that the right end of the oscillating member 41 is lifted, and further the scraping member 20 at the right end is driven to be retracted and away from the glass surface and not work, and meanwhile, the left end of the oscillating member 41 is driven to fall down, and the scraping member 20 at the left end is driven to be extended and close to the glass surface (for example, to be attached to the glass surface) to conduct scraping work.

When the glass is moved to the edge of the glass, the scraping device 100 can be controlled to move leftwards, and at this time, the direction of the friction force applied to the friction member 30 changes, so that the swinging member 41 can be driven to swing in the opposite direction, and the positions of the double scraping members 20 are switched.

As shown in fig. 4-6, the oscillating member 41 can be fixedly coupled to the scraping member 20 by a mounting seat 80.

Further, the oscillating member 41 and the mount 80 can be formed by an integral molding process, thereby facilitating the improvement of the mechanical strength of the connection therebetween.

Alternatively, the integral molding process may be an injection molding process.

The swinging member 41 is hinged to the inner surface of the base 10, and the application does not limit how the swinging member 41 is hinged to the inner surface of the base 10. For example, a rotating shaft may be provided on a side wall of the swinging member 41, and the rotating shaft may be rotatably connected to a rotating shaft mounting seat on the inner surface of the base 10, so as to realize the hinge joint of the two.

In addition, in other embodiments, a hinge hole is formed in the middle of the swinging member 41, a hinge shaft is fixedly disposed in the hinge hole, and a hinge seat is disposed on the inner surface of the base, extends into the hinge hole and is rotatably connected with the hinge shaft. At this time, a mounting hole is formed on the hinge base, and the hinge shaft can be inserted into the mounting hole and can rotate relative to the mounting hole. With the above arrangement, the bottom surface of the swinging member is made closer to the inner surface of the base, thereby making the swinging of the swinging member more controllable.

In the embodiment of the present application, as shown in fig. 6, the two ends of the swinging member 41 are respectively provided with a protruding portion 41a relative to the middle portion, and the lower surface of the translation member 43 is slidably connected with the upper surface of the swinging member 41 to press the protruding portions 41a, so as to drive the swinging member 41 to swing.

That is, the translation member 43 is disposed above the swinging member 41 and is slidably connected to the swinging member, and since the swinging member 41 is hinged to the inner surface of the base 10, the swinging member 41 is provided with a protruding portion 41a at each of both ends thereof, and the protruding portion 41a is higher than the middle portion of the swinging member 41. Since the translation member 43 is restricted to move back and forth in the horizontal direction, when the translation member 43 moves toward one end of the swinging member 41, the protrusion 41a of the end is pressed, and the end of the swinging member 41 is driven to be pressed down and the other end is tilted up.

Specifically, when the scraping device 100 moves to the right, the friction member 30 moves to the left due to the friction force to the left, and at this time, the link member 42 drives the translation member 43 to move to the left, and the translation member 43 presses the protrusion 41a at the left end of the swinging member 41, so that the left end of the swinging member 41 is pressed down and the right end is tilted up. The wiper member 20 at the left end is further caused to be pressed down close to the glass surface for wiping operation, and the wiper member 20 at the right end is caused to be tilted away from the glass surface for non-operation.

Further, as shown in fig. 6, the translation member 43 is divided into a left portion connected to the friction member 30 through the connecting member 42 (i.e., the second sawtooth structure 43a is provided on the left portion), and a right portion slidably connected to the swinging member 41, and the shape of the right portion is adapted to the shape of the swinging member 41, so as to facilitate sliding relative to the swinging member 41 and to facilitate pressing the swinging member 41.
