As shown in fig. 1-6, the present embodiment provides a scraping device 100 comprising a base 10, double scraping members 20 (i.e., two scraping members 20), a friction member 30, and a transmission assembly 40.
Wherein, the double scraping members 20 are respectively arranged at two opposite sides of the base 10, the friction members 30 are movably arranged on the outer surface 11 of the base 10, and the friction members 30 are in transmission connection with the double scraping members 20 through the transmission assembly 40. The outer surface 11 of the base 10 is a surface where the base 10 abuts against the surface to be cleaned, or the outer surface 11 is a surface where the base 10 abuts against the surface to be cleaned.
When the scraping device 100 moves to scrape the surface to be cleaned, the friction member 30 moves backward with respect to the base 10 by the frictional force with the surface to be cleaned, so that the friction member 30 drives the scraping member 20 located at the front side in the traveling direction away from the surface to be cleaned by the transmission assembly 40 without working, and drives the scraping member 20 located at the rear side in the traveling direction close to the surface to be cleaned to perform scraping work (for example, to perform wiping).
In an embodiment of the present application, the scraping device 100 includes two scraping members 20 disposed on opposite sides of the base 10, such as 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 is capable of rubbing against a surface to be cleaned to generate a frictional force, and the frictional force generated is sufficiently large that the friction member 30 is capable of moving rearwardly relative to the outer surface 11 (i.e., relative to the base 10) under the influence of the frictional force, and further drives the two scraping members 20 in motion via 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, so as to form an internally hollow accommodating cavity, and the transmission assembly 40 is disposed in the accommodating cavity. The friction member 30 is in driving connection with the double scraper members 20 by means of a driving assembly 40, i.e. the friction member 30 is capable of driving the two scraper members 20 in motion by means of the driving assembly 40.
The specific form of the drive assembly 40 is not limited by the present application. For example, any of a number of different components (gears, racks, cams, eccentrics, slides, belts, links, etc.), different connection relationships (abutment, articulation, sliding connection, gear-rack connection, belt connection, pin-runner connection, etc.), may be included to effect the transfer of the motion of the friction member 30 to the two wiper members 20 and thus drive the wiper members 20 in motion.
In the embodiment of the present application, the scraping device 100 may be moved to scrape the surface to be cleaned, the user may manually move the scraping device 100 to wipe the surface to be cleaned, or the internal motor may drive the scraping device 100 to move to scrape the surface to be cleaned, which is not limited in the present application.
Optionally, in other embodiments, the scraping device 100 further includes a walking assembly, where the walking assembly includes a walking motor, a walking wheel, and other devices, so that the scraping device 100 may perform automatic walking without manual driving.
Alternatively, in other embodiments, the scraping device 100 may be a glass wiping robot, which includes sensors and an intelligent control system, etc. in addition to the above-described travelling assembly, for example, capable of planning a wiping route.
In the embodiment of the present application, the friction member 30 is not operated by driving the scraping member 20 located at the front side in the traveling direction away from the surface to be cleaned by the transmission assembly 40, and the scraping member 20 located at the rear side in the traveling direction is driven to approach the surface to be cleaned for scraping operation.
Wherein driving the scraper 20 away from the surface to be cleaned may be driving the scraper 20 to retract into the interior of the scraper 100, or may be by other means, such as folding, pushing the scraper 20 over, etc., so that the front end of the scraper 20 can be moved away from the surface to be cleaned, thereby enabling the scraper 20 to be deactivated.
Accordingly, the wiper 20 may be driven to approach the surface to be cleaned to perform a wiping operation, or the wiper 20 may be driven to protrude toward the surface to be cleaned, or may be driven by other means such as raising (straightening) the wiper 20, etc., so that the front end of the wiper 20 approaches the surface to be cleaned (e.g., abuts against the surface to be cleaned) to enable a wiping operation. The present application is not limited to the operating form of the scraper member 20, as long as the scraper member 20 can be switched between operating and not operating.
In an embodiment of the present application, as shown in fig. 2-4, a wiper 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 wipe 90 may be in two pieces, disposed opposite each other on opposite sides of the base 10.
Further, as shown in fig. 2, the friction member 30 is disposed in the wiper 90, and the friction member 30 protrudes from the wiping surface of the wiper 90, so that the friction member 30 can perform better relative friction with the surface to be cleaned.
As shown in FIG. 5, the outer surface 11 of the base 10 may be stepped with opposite sides protruding in the middle so that the wiping surface of the wipe 90 is flush with the outer surface 11 of the middle portion of the base 10 after the wipe 90 is secured over the outer surfaces 11 on both 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, so that a certain movable space is reserved for the scraping members 20. As shown in fig. 4, when the scraping device 100 moves in the direction B (i.e., right side in the drawing) to scrape a surface to be cleaned (not shown in the drawing), the friction member 30 is moved backward (i.e., leftward) with respect to the base 10 by a friction force, the front-side scraping member 20 (i.e., right-side scraping member 20) is further retracted away from the belt cleaning surface by the transmission assembly 40 inside the scraping device 100 without scraping, and the rear-side scraping member 20 (i.e., left-side scraping member 20) is extended to come close to the surface to be cleaned (at this time, the front end of the rear-side scraping member 20 may abut against the surface to be cleaned) to perform scraping.
In the embodiment of the present application, the scraping device 100 may be used to scrape and clean a glass surface, a desktop, a wall surface, a ground surface, a blackboard surface, etc., that is, the surface to be cleaned may be any one of a glass surface, a desktop, a wall surface, a ground surface, a blackboard surface, etc., which is not limited in this application.
As shown in fig. 1-5, the scraping device 100 further comprises a mounting block 80, the scraping element 20 being secured to the mounting block 80, the transmission assembly 40 being in transmission connection with the scraping element 20 via the mounting block 80.
As shown in fig. 1-4, a gap is formed between the side wall 62 of the top cover 60 and the base 10 that provides a movable space for the scraper 20 to enable the scraper 20 to be moved away from or toward the surface to be cleaned.
The specific structure of the scraping member 20 is not limited in the present application, and the scraping member 20 may be any one of a bar, a blade, a brush cleaner, and the like capable of performing a scraping operation, for example.
In an embodiment of the application, the scraping element 20 may be a scraper bar.
Alternatively, the scraping strip can be made of plastic or rubber materials.
Optionally, the scraping strips are arc-shaped, and the opposite ends of the middle part of the scraping strips protrude in a direction away from the base 10 (namely, the two scraping strips opposite to each other are in a ()' shape at the moment), so that water collection can be better performed.
Alternatively, the scraping element 20 on each side may be comprised of a plurality of scraping strips (or blades, brushes, etc.). For example, the plurality of wiper strips may be in tandem or parallel to one another to form the wiper 20.
The friction member 30 should have a sufficient coefficient of friction to generate sufficient friction, and the friction member 30 should also be resistant to wear, immersion, and corrosion. The specific form of the friction member 30 is not limited by the present application. In the embodiment of the present application, 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. According to the different surfaces to be cleaned, the friction blocks can rotate correspondingly and are made of different materials.
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, etc.
More preferably, the friction block is composed of a cowhide having a suitable coefficient of friction, being inexpensive and readily available, and being resistant to wear, immersion, corrosion, and having a long service life.
It will be appreciated that the amount of displacement of the friction member 30 relative to the base 10 is limited and controllable, and in embodiments of the present application, the friction member 30 is quickly moved to and held at a maximum displacement by friction force, at which time the two scraping members 20 are brought to and held at the preset position. In this preset position, one of the scraping elements 20 is retracted and the other scraping element 20 is extended to enable scraping operation, at which time the scraping device 100 moves as a whole to cause the rear scraping element 20 to perform scraping operation, during which the friction element 30 remains stationary relative to the base 10, with no relative movement therebetween, that is to say, the friction element 30 and the base 10 are displaced relative to each other only in the first case when the scraping device 100 is brought into engagement with the surface to be cleaned to start the scraping action, and in the second case when the scraping device 100 is reversed and in both cases the relative displacement of the friction element 30 and the base 10 occurs instantaneously, and then remains relatively stationary in the above-mentioned preset position.
According to the scraping device 100 provided by the embodiment of the application, the friction piece 30 arranged on the base 10 can generate friction with the surface to be cleaned to generate friction force, when the scraping device 100 moves rightwards, the friction piece 30 moves leftwards due to the leftwards friction force, and the right scraping piece 20 can be further driven to be retracted and not operated through the transmission assembly 40, and the left scraping piece 20 is driven to be extended to carry out scraping operation. When the scraping device 100 is moved to the edge of the surface to be cleaned, the scraping device 100 can be directly controlled to move leftwards without rotating the scraping device 100, and at this time, the friction member 30 drives the positions of the double scraping members 20 to be switched by the transmission assembly 40 under the action of friction force, namely, the right scraping member 20 is extended to perform scraping operation, and the left scraping member 20 is retracted to be not operated. The whole scraping process of the scraping device 100 provided by the embodiment of the application has continuity, can wipe the surface to be cleaned in a reciprocating manner like a blackboard, is simpler and more convenient to operate, can improve the wiping efficiency of a user, and can not form wiping dead angles on the surface to be cleaned, thereby being beneficial to improving the wiping effect.
For the purpose of more complete description of the function of the scraping device 100, reference is made to the front side scraping member 20, the rear side scraping member 20, and the left side scraping member 20, the right side scraping member 20, both for the purpose of illustrating the two scraping members 20 disposed opposite each other, and in use, whether the scraping member 20 performs the scraping operation by traveling back and forth or the scraping operation by moving left and right, and neither scraping member 20 performs the scraping operation, as the present application is not limited thereto.
For convenience of description and understanding, the scraping device 100 provided by the present application will be further described with a glass surface as a 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, the base 10 is provided with a connecting through hole 12 penetrating through the base 10, and the transmission assembly 40 includes a connecting piece 42 movably arranged in the connecting through hole 12 and a translation piece 43 movably arranged in the base 10.
When the scraping means is moved to scrape the surface to be cleaned, the friction member 30 drives the translation member 43 by the connecting member 42 to move rearward in the traveling direction with respect to the base 10, the translation member 43 further drives the scraping member 20 located on the front side in the traveling direction away from the surface to be cleaned without operation, and drives the scraping member 20 located on the rear side in the traveling direction close to the surface to be cleaned to perform scraping operation.
That is, the friction member 30 drives the translation member 43 to move via the link member 42, and the translation member 43 is restricted to move only in the horizontal direction and not in the vertical direction. Under the action of the friction element 30, the translation element 43 is able to move backwards in relation to the base 10 in the direction of travel, the translation element 43 transmitting this movement further to the double scraper 20, thus driving the scraper 20 to move.
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 can be transferred to the translation member 43, and the translation member 43 is driven to translate.
Fig. 7 is a schematic cross-sectional view of the AA view of fig. 3. As shown in fig. 7, in the embodiment of the present application, the connecting member 42 includes a driving belt 42a and two pulleys 42b, the two pulleys 42b are disposed at intervals and rotatably connected to the base 10, the driving belt 42a is disposed around the two pulleys 42b, one side of the driving belt 42a is fixedly connected to the friction member 30, and the other side is in driving connection with the translation member 43.
Specifically, in this embodiment, the transmission may be performed by the transmission belt 42a, at this time, a slot may be formed on the wall of the connection through hole 12, and the pulleys 42b are rotatably connected in the slot, and the two pulleys 42b are disposed at intervals, and the transmission belt 42a is wrapped around the outer sides of the two pulleys 42 b. The outer diameters of the two pulleys 42b are the same, and the planes of the two rotating 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 friction force, the transmission belt 42a can be driven to rotate, and the translation member 43 is driven to move by the transmission belt 42 a.
The transmission form of the transmission belt 42a and the translation member 43 is not limited in the present application. In the embodiment of the present application, the transmission belt 42a is engaged with the translation member 43.
At this time, a first saw-tooth structure 42c is provided on the side of the driving belt 42a facing the translation member 43, a second saw-tooth structure 43a is provided on the side of the translation member 43 facing the driving belt 42a, and the driving belt 42a and the translation member 43 are engaged and driven by the first saw-tooth structure 42c and the second saw-tooth structure 43 a.
Further, for better connection fixation 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, and the pulley 42b is a saw gear, and the toothed belt and the saw gear are meshed 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, the double scraping members 20 are fixedly connected to both ends of the swinging member 41, respectively, and the translation 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 translation member 43 drives one end of the swinging member 41 located at the front side in the traveling direction to be away from the surface to be cleaned, and drives one end located at the rear side in the traveling direction to be close to the surface to be cleaned.
Specifically, the swinging member 41 is hinged to the inner surface of the base 10, and can swing relative to the base 10, and two ends of the swinging member 41 are fixedly connected with the double scraping members 20 respectively, so that the swinging member 41 can drive the double scraping members 20 to swing.
Thus, when the scraping device 100 moves rightwards, the friction member 30 moves leftwards due to the leftwards friction force, and at this time, the friction member 30 can drive the swinging member 41 to swing sequentially through the connecting member 42 and the translation member 43, so that the right end of the swinging member 41 is lifted, and then the scraping member 20 at the right end is driven to be retracted and not work away from the glass surface, and meanwhile, the left end of the swinging member 41 is driven to be dropped, 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 perform scraping work.
When the glass is moved to the edge position, the scraping device 100 can be controlled to move leftwards, and at the moment, the direction of the friction force applied to the friction piece 30 is changed, so that the swinging piece 41 can be driven to swing in the opposite direction, and the positions of the double scraping pieces 20 are switched.
As shown in fig. 4-6, the oscillating member 41 may be fixedly coupled to the scraper member 20 by a mounting block 80.
Further, the swinging member 41 and the mount 80 may be manufactured by an integral molding process, thereby advantageously improving 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 present application is not limited to how the swinging member 41 is hinged to the inner surface of the base 10. For example, a rotation shaft may be provided on a side wall of the swing member 41, and the rotation shaft may be rotatably coupled to a rotation shaft mounting seat on an inner surface of the base 10, thereby achieving hinge connection of the two.
In addition, in other embodiments, a hinge hole is provided in the middle of the swing member 41, a hinge shaft is fixedly provided in the hinge hole, and a hinge seat is provided on the inner surface of the base, and extends into the hinge hole and is rotatably connected with the hinge shaft. At this time, a mounting hole is formed in the hinge seat, and the hinge shaft may be fitted into the mounting hole and may be rotated with respect to the mounting hole. By the arrangement, the bottom surface of the swinging piece is closer to the inner surface of the base, so that the swinging of the swinging piece is more controllable.
The present application is not limited as to how the translation member 43 is in driving connection with the swing member 41. In the embodiment of the present application, as shown in fig. 6, the opposite middle parts of the two ends of the swinging member 41 are respectively provided with a protruding part 41a, and the lower surface of the translation member 43 is slidably connected with the upper surface of the swinging member 41, so as to press the protruding part 41a, thereby driving the swinging member 41 to swing.
That is, the translation member 43 is disposed above the swing member 41 and both are slidably connected, and since the swing member 41 is hinged to the inner surface of the base 10, both ends of the swing member 41 are each provided with a boss 41a, which boss 41a is higher than the middle portion of the swing member 41. Since the translation member 43 is restricted to move forward and backward in the horizontal direction, when the translation member 43 moves toward one end of the swinging member 41, the protrusion 41a of the end can be pressed, and the end of the swinging member 41 is driven to be depressed, and the other end is tilted.
Specifically, when the scraping device 100 moves rightward, the friction member 30 moves leftward due to the leftward friction force, and at this time, the translation member 43 is driven to move leftward by the connection member 42, and the translation member 43 presses the boss 41a at the left end of the swing member 41, so that the left end of the swing member 41 is depressed and the right end is tilted. The wiper 20 further driving the left end is pressed close to the glass surface to perform wiping work, and the wiper 20 driving the right end is tilted away from the glass surface to be inoperative.
Further, as shown in fig. 6, the translation member 43 is divided into a left side portion and a right side portion, the left side portion is connected with the friction member 30 through the connection member 42 (i.e., the second saw tooth structure 43a is provided at the left side portion), the right side portion is slidably connected with the swing member 41, and the shape of the right side portion can be adapted to the shape of the swing member 41 to facilitate sliding relative to the swing member 41 and to facilitate pressing of the swing member 41.
Fig. 8 is a schematic diagram of the connection of the orientation assembly 50 provided by an embodiment of the present application. As shown in fig. 5, 6 and 8, the scraping device 100 further comprises an orientation assembly 50, the orientation assembly 50 being adapted to orient the displacement of the translatory element 43 such that the translatory element 43 remains reliably connected to the oscillating element 41. The orientation assembly 50 controls the displacement of the translators 43 so that the translators 43 do not disengage from the oscillating members 41, thereby improving the usability of the scraping device 100.
Here, the orientation unit 50 reliably connects the translation member 43 and the swinging member 41, and the orientation unit 50 controls the movement track of the translation member 43, so that the translation member 43 and the swinging member 41 are not separated, always remain connected, and relatively displace according to a predetermined track.
As shown in fig. 8, in the embodiment of the present application, the orientation assembly 50 includes a roller 51 and a guide rail 52 that are used in cooperation with each other, the roller 51 is rotatably disposed on the upper surface of the translation member 43 through a rotation shaft, and the guide rail 52 is fixedly disposed on the inner surface of the top wall 61. The roller 51 can roll along the guide rail 52.
In other embodiments, the positions of the rollers 51 and the guide rails 52 may be reversed. The roller 51 may be rotatably provided on the inner surface of the top wall 61, and the guide rail 52 may be fixedly provided on the upper surface of the translation member 43, similarly to the above.
The specific arrangement of the orientation assembly 50 is not limited in the present application, as long as the above-described displacement orientation can be achieved. For example, in other embodiments, the orientation assembly may include a slide pin and a slide slot that are mutually adapted. At this time, a mounting wall may be provided at an edge of the base 10, a slide pin may be provided on one of an inner surface of the mounting wall and a side surface of the translation member, and a slide groove may be provided on the other of the inner surface of the mounting wall and the side surface of the translation member.
In the embodiment of the application, as shown in fig. 3, 5 and 6, the friction members 30 comprise two friction members 30 disposed on opposite sides of the outer surface 11, the two friction members 30 each being in driving engagement with the double scraper members 20 by a set of driving assemblies 40. Wherein, two translation members 43 in two sets of transmission components 40 are fixedly connected through a synchronizing member 70 so as to realize synchronous movement of the two translation members 43. Through the arrangement, on one hand, synchronous movement of the two translation members 43 can be realized, and on the other hand, better control of displacement of the translation members 43 is facilitated, and reliable connection of the translation members 43 and the swinging members 41 is facilitated.
As shown in fig. 6, in the embodiment of the present application, the synchronizing member 70 is in a frame shape, and two sides of the synchronizing member are fixedly connected with the translation member 43, respectively, and in other embodiments, the synchronizing member 70 may also be in other shapes, such as an "X" shape, etc., which is not limited in the present application.
The two translation members 43 and the synchronizing member 70 are manufactured by an integral molding process. By the arrangement, the stability of mechanical connection can be improved. For example, the integral molding process may be injection molding.
As shown in fig. 6, in the embodiment of the present application, two swinging members 41 are also provided at opposite sides of the base 10, and each swinging member 41 is connected to the double scraping member 20, by which the scraping member 20 can be more controlled to be lifted and lowered.
Alternatively, the two swinging members 41 and the two mounting seats 80 may be manufactured by an integral molding process to improve the stability of the mechanical connection. For example, the integral molding process may be injection molding.
