Abstract
Description
Technical Field
[0001] This application relates to the field of daily cleaning products technology, and in particular to a scraping device and scraping assembly. Background Technology
[0002] Over time, glass windows are exposed to both internal and external environmental factors, accumulating dust and impurities on their surface. This affects the appearance of the windows and also hinders light transmission, necessitating frequent cleaning. Magnetic window cleaners have greatly simplified window cleaning. They utilize two mutually attracting cleaning plates that adhere to the inner and outer surfaces of the glass. Users push the inner plate, moving the outer plate along with it, achieving simultaneous cleaning of both the inner and outer surfaces of the window. This method offers high cleaning efficiency and safety.
[0003] In related technologies, glass cleaners typically have a wiping agent and a squeegee on the contact surface with the glass. The wiping agent is used to scrub and clean the glass surface, removing larger dirt particles, while the squeegee removes water stains. The wiping agent is located in the center of the contact surface, and the squeegee is usually a single piece located at the edge of the contact surface.
[0004] When using this glass cleaner, the user needs to move it with the object to be wiped in front and the squeegee behind to clean the glass surface. If the user needs to change direction during movement, they must rotate the cleaner to continue cleaning in the opposite direction, resulting in a discontinuous cleaning action and inconvenience. Furthermore, this type of glass cleaner is not effective at cleaning corners of the glass, easily creating blind spots. These factors contribute to the low cleaning efficiency of existing glass cleaners. Summary of the Invention
[0005] This application provides a scraping device and scraping assembly, which has higher wiping efficiency and is conducive to improving the wiping effect.
[0006] In a first aspect, a scraping device is provided, comprising a base, dual scraping components, a friction component, and a transmission assembly. The dual scraping components are respectively disposed on opposite sides of the base, and the friction component is movably disposed on the outer surface of the base. The friction component is connected to the dual scraping components via the transmission assembly. When the scraping device moves to scrape the surface to be cleaned, the friction component moves backward relative to the base under the action of friction with the surface to be cleaned. This causes the friction component to drive the scraping component located at the front side in the travel direction away from the surface to be cleaned and stop working, and drives the scraping component located at the rear side in the travel direction to approach the surface to be cleaned for scraping.
[0007] According to the scraping device provided in this application, the friction element disposed on the outer surface of the base can generate frictional force by rubbing against the surface to be cleaned. When the scraping device moves to the right, the friction element moves to the left relative to the base due to the frictional force to the left. Furthermore, the right-side scraper can be retracted and inactive via a transmission assembly, while the left-side scraper is extended for scraping. When the scraping device is moved to the edge of the surface to be cleaned, there is no need to rotate the scraping device; it can be directly controlled to move to the left. At this time, under the action of friction, the friction element drives the position of the two scrapers to switch via the transmission assembly. That is, the right-side scraper is extended for scraping, while the left-side scraper is retracted and inactive. The scraping device provided in this application provides a continuous scraping process, capable of repeatedly wiping the surface to be cleaned like erasing a blackboard. This simplifies operation, improves user wiping efficiency, and avoids creating dead corners on the surface, thus enhancing the wiping effect.
[0008] Optionally, the scraping device moves to scrape the surface to be cleaned. This can be done by the user manually moving the scraping device to wipe the surface, or by an internal motor driving the scraping device to move to scrape the surface to be cleaned. This application does not limit this.
[0009] Optionally, the scraping device also includes a walking component, which includes a walking motor and walking wheels, thereby enabling the scraping device to move automatically without human intervention.
[0010] Optionally, the wiping device can be a glass cleaning robot, which, in addition to the aforementioned walking components, also includes sensors and an intelligent control system, such as the ability to plan the wiping route.
[0011] Alternatively, driving the scraper away from the surface to be cleaned can be achieved by driving the scraper to retract into the scraping device, or by other means, such as folding or pushing the scraper away, so that the front end of the scraper can move away from the surface to be cleaned, thereby preventing the scraper from working.
[0012] Optionally, driving the scraper to approach the surface to be cleaned for scraping can be achieved by extending the scraper towards the surface, or by other means, such as raising (straightening) the scraper so that its front end is close to (e.g., in contact with) the surface to be cleaned, thereby enabling the scraping operation. This application does not limit the operating mode of the scraper, as long as it can switch between working and non-working modes.
[0013] Optionally, to better handle the cleaning of the surface, a wiping material is also fixedly mounted on the outer surface of the base. For example, the wiping material can be a wiping cloth or a sponge. There can be two wiping materials, positioned opposite each other on opposite sides of the base.
[0014] Optionally, the friction element is disposed within the wiping material and protrudes from the wiping surface of the wiping material, thereby enabling the friction element to better rub against the surface to be cleaned.
[0015] Optionally, the outer surface of the base can be stepped, with the middle protruding relative to the two sides. In this way, after the wiping material is fixed on the mating surfaces on both sides, the wiping surface of the wiping material can be flush with the outer surface of the middle part of the base, thus making it convenient for the user to wipe and use.
[0016] Optionally, in the free state, the front ends of the two scraping parts on the left and right sides can be slightly higher than the wiping surface of the object being wiped, thus providing some room for the scraping parts to move.
[0017] Optionally, the scraping device can be used to scrape and clean surfaces such as glass surfaces, desktops, walls, floors, and blackboards. In other words, the surface to be cleaned can be any one of glass surfaces, desktops, walls, floors, blackboards, etc., and this application does not limit it.
[0018] Optionally, the scraping component can be any of the following devices capable of performing scraping operations: scraper, scraper blade, cleaning brush, etc.
[0019] Alternatively, the scraper can be made of plastic or rubber.
[0020] Optionally, the scraper is arc-shaped, with the two opposite ends protruding away from the base (i.e., the two opposite scrapers form a "()" shape), which allows for better water collection.
[0021] Optionally, the scraping component on each side may consist of multiple scraper strips (or scrapers, cleaning brushes, etc.). For example, the multiple scraper strips may be connected one after another or arranged in parallel to each other to form the scraping component.
[0022] In one possible design, the transmission assembly includes a swing member hinged to the inner side of the base, and the dual scraping members are fixedly connected to both ends of the swing member; the friction member is drivenly connected to the swing member, and when the scraping device moves to scrape the surface to be cleaned, the friction member drives one end of the swing member located in the forward direction of travel away from the surface to be cleaned, and drives one end located in the rear direction of travel closer to the surface to be cleaned.
[0023] According to the scraping device provided in this application, the two scraping components are fixedly mounted on both sides of the swing component, and the transmission of the friction component to the scraping component is more stable and controllable, thereby enabling more convenient and efficient switching control of the two scraping components.
[0024] Optionally, the swing element is hinged to the inner surface of the base.
[0025] Optionally, a hinge hole is provided in the middle of the swing member, and a hinge shaft is fixedly installed in the hinge hole. A hinge seat is provided on the inner surface of the base, and the hinge seat extends into the hinge hole and is rotatably connected to the hinge shaft. With the above arrangement, the bottom surface of the swing member is closer to the inner surface of the base, thereby making the swing of the swing member more controllable.
[0026] Alternatively, the swing element can also be hinged to the inner surface of the top cover. For example, the inner surface of the top wall or the outer surface of the side wall.
[0027] In one possible design, the transmission assembly further includes a translational member, which is driven by the friction member to move rearward relative to the base in the direction of travel, and the translational member further drives the oscillating member to oscillate.
[0028] Optionally, the translational component can directly drive the oscillating component to oscillate, or it can be indirectly driven to oscillate through other components.
[0029] In one possible design, the translational member moves backward relative to the oscillating member to press the oscillating member, thereby driving the oscillating member to oscillate.
[0030] Optionally, the translational member can also lift (or support) the oscillating member, thereby driving the oscillating member to oscillate.
[0031] In one possible design, the two ends of the swing member have raised portions relative to the middle portion, and the translational member moves backward to press the raised portions, thereby driving the swing member to swing.
[0032] Optionally, the overall shape of the swinging component can be U-shaped, V-shaped, W-shaped, etc.
[0033] In one possible design, the lower surface of the translational member is slidably connected to the upper surface of the oscillating member. With this configuration, the oscillating member can support and limit the translational member's movement, thus making the translational member's motion more controllable.
[0034] Optionally, the translational member and the oscillating member can also be connected by a rolling connection. In this case, a roller can be provided on the mating surface of one of them, and a guide rail adapted to the roller can be provided on the other.
[0035] Optionally, the translational member and the oscillating member may not be connected (or in contact), and the oscillating member is pressed only after the two have undergone relative displacement.
[0036] In one possible design, the translational member or the oscillating member is provided with a sliding rib, and the translational member and the oscillating member are slidably connected by the sliding rib. This arrangement allows for smoother relative sliding between the translational member and the oscillating member.
[0037] In one possible design, the translational member is provided with a first sliding pin, and the swing member is provided with an inclined guide groove. The first sliding pin is slidably disposed in the inclined guide groove. The translational member moves backward to press the swing member through the inclined guide groove, thereby driving the swing member to swing.
[0038] Optionally, the first sliding pin can be a single pin, and the inclined guide groove can be U-shaped or V-shaped.
[0039] Optionally, there can be two first sliding pins and two inclined guide grooves arranged alternately. The first sliding pins and the inclined guide grooves correspond one-to-one. The inclined guide grooves are inclined upward from the inside to the outside and are connected to a horizontally arranged clearance groove on the inner side.
[0040] In one possible design, the scraping device further includes a directional component for orienting the displacement of the translational member, ensuring a reliable connection between the translational member and the oscillating member. This directional component can control the displacement of the translational member, preventing it from detaching from the oscillating member, thereby improving the performance of the scraping device.
[0041] In one possible design, the scraping device includes a top wall, and the orientation component includes a roller and a guide rail that cooperate with each other; the roller is rotatably disposed on one of the inner surface of the top wall and the upper surface of the translational member, and the guide rail is disposed on the other of the inner surface of the top wall and the upper surface of the translational member.
[0042] In one possible design, the base has an edge with a mounting wall, and the orientation component includes a mutually adapted second sliding pin and a sliding groove; the second sliding pin is disposed on one of the inner surface of the mounting wall and the side surface of the translational member, and the sliding groove is disposed on the other of the inner surface of the mounting wall and the side surface of the translational member.
[0043] In one possible design, the scraping device further includes a connector, and the base has a connecting through hole. The connector is movably disposed in the connecting through hole, and the friction element is connected to the transmission assembly through the connector.
[0044] In one possible design, the friction element is disposed on the connector, which is connected to the transmission assembly via an elastic element, allowing the connector to elastically extend and retract in a direction perpendicular to the outer surface of the base. This configuration enables timely compensation after wear of the friction element, ensuring more reliable contact between the friction element and the glass surface to generate friction.
[0045] Alternatively, the elastic element can be a spring.
[0046] In one possible design, the friction element drives the connector to move along the length of the connecting through hole, the length of the travel being parallel to the direction of travel.
[0047] In one possible design, the friction element is fixedly mounted on the connector, and the friction element includes at least a friction block or a suction cup.
[0048] Here, "friction component" is a general concept, including friction blocks or suction cups, etc. Friction components can also be other parts that can rub against the surface to be cleaned to generate friction. This application does not limit the specific form or quantity of friction components. For example, the friction component may include one friction block and one suction cup, or it may include multiple suction cups (e.g., two) or multiple friction blocks, etc.
[0049] Alternatively, the friction block can be made of materials such as plastic, rubber, resin, metal, or leather.
[0050] Optionally, the friction block can be made of leather, which can be animal leather or synthetic leather. For example, the animal leather can be cowhide, sheepskin, donkey hide, etc.
[0051] Optionally, the friction block is made of cowhide, which has a suitable coefficient of friction, is inexpensive and readily available, and is wear-resistant, immersion-resistant, corrosion-resistant, and has a long service life.

[0054] In one possible design, the contact surface between the translational member and the base is provided with multiple smooth protrusions. This reduces the friction between the translational member and the base, facilitating relative sliding between them.
[0055] In one possible design, the friction element comprises two friction elements disposed on opposite sides of the base, each friction element being connected to the dual scraping element via a transmission assembly; wherein, the two translational elements in the two transmission assemblies are fixedly connected by a synchronizing element to achieve synchronous movement of the two translational elements.
[0056] Optionally, the two translational members and the synchronization member are manufactured using an integral molding process.
[0057] In one possible design, the scraping device further includes a mounting base, through which the oscillating member is fixedly connected to the scraping member.

[0085] The technical solutions of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.
[0086] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0087] In the description of this application, it should be understood that the terms "upper", "lower", "side", "inner", "outer", "top", "bottom", etc., indicate the orientation or positional relationship based on the installation orientation or positional relationship, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0088] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same component or part. For the same part in the embodiments of this application, the reference numerals may only be used to mark one part or component as an example. It should be understood that the reference numerals are also applicable to other identical parts or components.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.
[0090] Firstly, this application provides a scraping device, which can be the aforementioned glass wiper, capable of scraping and cleaning glass surfaces. Furthermore, this scraping device can also be used to scrape and clean other surfaces such as desktops, walls, floors, and blackboards; this application does not limit its application to this.
[0091] Figure 1 This is a schematic diagram of the overall assembly of the scraping device 100 provided in the embodiments of this application. Figure 2 This is a side view of the scraping device 100 provided in the embodiments of this application. Figure 3 This is a bottom view of the scraping device 100 provided in the embodiments of this application. Figure 4 This is a schematic diagram of the usage state of the scraping device 100 provided in the embodiments of this application. Figure 5 This is an exploded view of the scraping device 100 provided in an embodiment of this application. (See attached image.) Figure 1-5 As shown, the scraping device 100 provided in this application embodiment includes: a base 10, a double scraping member 20 (i.e., two scraping members 20), a friction member 30, and a transmission assembly 40.
[0092] The dual scraping components 20 are respectively disposed on opposite sides of the base 10, and the friction component 30 is movably disposed on the outer surface 11 of the base 10. The friction component 30 is connected to the dual scraping components 20 via the transmission assembly 40. The outer surface 11 of the base 10 is the surface on which the base 10 abuts against the surface to be cleaned, or in other words, the outer surface 11 is also the surface on which the base 10 and the surface to be cleaned are in mutual contact.
[0093] When the scraping device 100 moves to scrape the surface to be cleaned, the friction member 30 moves backward relative to the base 10 under the action of friction with the surface to be cleaned, so that the friction member 30 drives the scraping member 20 located on the front side of the travel direction away from the surface to be cleaned and does not work, and drives the scraping member 20 located on the rear side of the travel direction to approach the surface to be cleaned to perform scraping work (e.g., wiping water).
[0094] In this embodiment, the scraping device 100 includes two scraping elements 20, respectively disposed on two opposite sides of the base 10, for example... Figure 1-4 On the two opposite long sides of the base 10, friction elements 30 are movably disposed on the outer surface 11 and can be displaced relative to the outer surface 11. In use, the friction elements 30 can generate frictional force by rubbing against the surface to be cleaned, and the generated frictional force is large enough that the friction elements 30 can move backward relative to the outer surface 11 (i.e., relative to the base 10) under the action of the frictional force, and further drive the two scraping elements 20 to move through the transmission assembly 40.
[0095] 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 circumferentially arranged around the top wall 61. The top cover 60 can be fixedly fitted onto the base 10, thereby forming an internally hollow receiving cavity. The transmission assembly 40 is disposed within this receiving cavity. The friction element 30 is connected to the dual scraping elements 20 via the transmission assembly 40, that is, the friction element 30 can drive the two scraping elements 20 to move via the transmission assembly 40.
[0096] This application does not limit the specific form of the transmission component 40. For example, it may include the cooperation of any number of different components (gears, racks, cams, eccentric wheels, sliders, belts, connecting rods, etc.) and different connection relationships (abutment, hinge, sliding connection, gear-rack connection, belt connection, pin-slide connection, etc.) to realize the transmission of the motion of the friction component 30 to the two scraping components 20, thereby driving the scraping components 20 to move.
[0097] In the embodiments of this application, the scraping device 100 moves to scrape the surface to be cleaned. This can be done by the user manually moving the scraping device 100 to wipe the surface to be cleaned, or by the internal motor driving the scraping device 100 to move to scrape the surface to be cleaned. This application does not limit this.
[0098] Alternatively, in other embodiments, the scraping device 100 may further include a walking component, which includes a walking motor and walking wheels, thereby enabling the scraping device 100 to walk automatically without human intervention.
[0099] Alternatively, in other embodiments, the wiping device 100 can be a glass cleaning robot, which, in addition to the aforementioned walking components, also includes sensors and an intelligent control system, such as the ability to plan the wiping route.
[0100] In this embodiment, the friction member 30 drives the scraping member 20 located at the front side of the travel direction away from the surface to be cleaned and does not work through the transmission assembly 40, and drives the scraping member 20 located at the rear side of the travel direction to approach the surface to be cleaned to perform scraping work.
[0101] The driving of the scraper 20 away from the surface to be cleaned can be achieved by driving the scraper 20 to retract into the scraping device 100, or by other means, such as folding or pushing the scraper 20, so that the front end of the scraper 20 can be away from the surface to be cleaned, thereby preventing the scraper 20 from working.
[0102] Accordingly, the squeegee 20 is driven close to the surface to be cleaned to perform the squeegee operation. This can be achieved by driving the squeegee 20 to extend towards the surface, or by other means, such as raising (straightening) the squeegee 20 so that its front end is close to (e.g., in contact with) the surface to be cleaned, thereby enabling the squeegee operation. This application does not limit the operating mode of the squeegee 20, as long as it can switch between working and non-working modes.
[0103] like Figure 2-4 As shown in this embodiment, in order to better clean the surface, a wiping material 14 is also fixedly provided on the outer surface 11 of the base 10. For example, the wiping material 14 can be a wiping cloth or a sponge. There can be two wiping materials 14, which are arranged opposite each other on opposite sides of the base 10.
[0104] Furthermore, such as Figure 2 As shown, the friction element 30 is disposed inside the wiping object 14 and protrudes from the wiping surface of the wiping object 14, thereby enabling the friction element 30 to better rub against the surface to be cleaned.
[0105] like Figure 5 As shown, the outer surface 11 of the base 10 can be stepped, with the middle protruding relative to the two sides. In this way, after the wiping material 14 is fixed on the outer surfaces 11 on both sides, the wiping surface of the wiping material 14 can be flush with the outer surface 11 of the middle part of the base 10, which makes it convenient for the user to wipe and use.
[0106] like Figure 2 As shown, in the free state, the front ends of the two scraping parts 20 on the left and right sides can be slightly higher than the wiping surface of the object 14, thus providing a certain amount of room for the scraping parts 20 to move. Figure 4As shown, when the scraping device 100 moves in direction B (i.e., to the right in the figure) to scrape the surface to be cleaned (not shown in the figure), the friction member 30 is subjected to friction and moves backward (i.e. to the left) relative to the base 10. Furthermore, the transmission component 40 inside the wiping device 100 drives the front scraping member 20 (i.e., the right scraping member 20) to be retracted away from the surface to be cleaned, so as not to perform scraping work, and drives the rear scraping member 20 (i.e., the left scraping member 20) to be extended to approach 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 scraping work.
[0107] In this application embodiment, the scraping device 100 can be used to scrape and clean surfaces such as glass surfaces, desktops, walls, floors, and blackboards. That is to say, the surface to be cleaned can be any one of glass surfaces, desktops, walls, floors, blackboards, etc., and this application does not limit it.
[0108] like Figure 1-5 As shown, the scraping device 100 also includes a mounting base 80, on which the scraping component 20 is fixed, and the transmission assembly 40 is connected to the scraping component 20 through the mounting base 80.
[0109] like Figure 1-4 As shown, a gap is formed between the sidewall 62 of the top cover 60 and the base 10, which provides room for the scraper 20 to move away from or near the surface to be cleaned.
[0110] This application does not limit the specific structure of the scraping component 20. For example, the scraping component 20 can be any of the following devices that can perform scraping operations: scraper, scraper, cleaning brush, etc.
[0111] In this embodiment, the scraping element 20 can be a scraper strip.
[0112] Alternatively, the scraper can be made of plastic or rubber.
[0113] Optionally, the scraper is arc-shaped, with the two opposite ends protruding away from the base 10 (i.e., the two opposite scrapers are in the shape of "()"), which can better collect water.
[0114] Optionally, the scraper 20 on each side may consist of multiple scraper strips (or scrapers, cleaning brushes, etc.). For example, the multiple scraper strips may be connected one after another or parallel to each other to form the scraper 20.
[0115] The friction element 30 should have a sufficient coefficient of friction to generate sufficient frictional force, and it should also be wear-resistant, immersion-resistant, and corrosion-resistant. This application does not limit the specific form of the friction element 30. In the embodiments of this application, the friction element 30 is a friction block. For example, the friction block can be made of materials such as plastic, rubber, resin, metal, or leather. Depending on the surface to be cleaned, the friction block can be adapted to rotate with different materials.
[0116] Preferably, the friction block can be made of leather, which can be animal leather or artificial leather. For example, the animal leather can be cowhide, sheepskin, donkey hide, etc.
[0117] More preferably, the friction block is made of cowhide, which has a suitable coefficient of friction, is inexpensive and readily available, and is wear-resistant, immersion-resistant, corrosion-resistant, and has a long service life.
[0118] It should be understood that the displacement of the friction element 30 relative to the base 10 is limited and controllable. In this embodiment, the friction element 30 is quickly moved to the maximum displacement position under the action of friction and is held at the maximum displacement position. At this time, the two scraping elements 20 are also driven to reach the preset position and are held at the preset position. At the preset position, one of the scraping elements 20 is retracted and does not work, while the other scraping element 20 is extended and can perform scraping work. At this time, the scraping device 100 moves as a whole to enable the rear scraping element 20 to perform scraping work. During the scraping work, the friction element 30 remains stationary relative to the base 10, and there is no relative movement between the two. That is to say, the friction element 30 and the base 10 only undergo relative displacement in the following two cases: the first case is when the scraping device 100 is attached to the surface to be cleaned and begins to scrape; the other case is when the scraping device 100 changes direction. In the above two cases, the relative displacement between the friction element 30 and the base 10 occurs instantaneously, and then it is held at the above preset position, remaining relatively stationary.
[0119] According to the scraping device 100 provided in this application embodiment, the friction element 30 disposed on the base 10 can generate frictional force by rubbing against the surface to be cleaned. When the scraping device 100 moves to the right, the friction element 30 moves to the left due to the frictional force to the left, and can further drive the right scraping element 20 to be retracted and not work through the transmission component 40, while driving the left scraping element 20 to be extended for scraping. When the scraping device 100 is moved to the edge of the surface to be cleaned, there is no need to rotate the scraping device 100; the scraping device 100 can be directly controlled to move to the left. At this time, under the action of frictional force, the friction element 30 drives the position of the two scraping elements 20 to switch through the transmission component 40, that is, the right scraping element 20 is extended for scraping, while the left scraping element 20 is retracted and not work. The scraping device 100 provided in this application embodiment has a continuous scraping process, and can repeatedly wipe the surface to be cleaned like wiping a blackboard. The operation is simpler, which can improve the user's wiping efficiency and will not form a wiping dead corner on the surface to be cleaned, thereby improving the wiping effect.
[0120] To more comprehensively describe the function of the scraping device 100, the terms mentioned above, whether referring to the front scraper 20, the rear scraper 20, the left scraper 20, or the right scraper 20, are all intended to illustrate that, in use, whether the two scraper 20 are moving back and forth or moving left and right to perform the wiping work, only one scraper 20 performs the wiping work while the other scraper 20 does not. This application does not limit this.
[0121] For ease of description and understanding, the following description will use a glass surface as the surface to be cleaned to further explain the scraping device 100 provided in this application. That is, the scraping device 100 in the following description can be understood as a glass wiper.
[0122] Figure 6 This is a schematic diagram of the installation structure of the swing member 41 provided in the embodiment of this application. Figure 7 This is a schematic diagram of the structure of the base 10 provided in the embodiments of this application. Figure 8 This is a schematic diagram of the connection structure between the swing member 41 and the scraper mounting base 80 provided in the embodiments of this application.
[0123] like Figure 5-8As shown, the transmission assembly 40 includes a swing member 41 hinged within the base 10, and two scraping members 20 fixedly connected to both ends of the swing member 41. A friction member 30 is drive-connected to the swing member 41. When the scraping device 100 moves to scrape the glass surface, the friction member 30 drives the front end of the swing member 41 away from the glass surface and drives the rear end of the swing member 41 closer to the glass surface. By fixing the two scraping members 20 to both sides of the swing member 41, the transmission of the scraping members 20 by the friction member 30 is more stable and controllable, enabling more convenient and efficient switching control of the two scraping members 20.
[0124] In this embodiment, the swing member 41 is hinged to the inner surface of the base 10. Specifically, the swing member 41 is hinged to the inner surface of the base 10 and can swing relative to the base 10. Both ends of the swing member 41 are fixedly connected to the double scraper member 20, thereby enabling the swing member 41 to drive the double scraper member 20 to swing.
[0125] Thus, when the scraping device 100 moves to the right, the friction element 30 moves to the left due to the frictional force to the left. At this time, the friction element 30 can drive the swinging element 41 to swing, so that the right end of the swinging element 41 is lifted, thereby driving the right end of the scraping element 20 to be retracted and away from the glass surface and stop working. At the same time, the left end of the swinging element 41 is dropped, driving the left end of the scraping element 20 to be extended and close to the glass surface (e.g., attached to the glass surface) to perform scraping work.
[0126] When the device moves to the edge of the glass, the scraping device 100 can be controlled to move to the left. At this time, because the direction of the friction force on the friction element 30 changes, the swinging element 41 can be driven to swing in the opposite direction, and the position of the double scraping element 20 is switched.
[0127] In this embodiment, the swing member 41 is hinged to the inner surface of the base 10. In other embodiments, the swing member 41 may also be hinged to other parts inside the scraping device 100, and this application does not limit this. For example, the swing member 41 may also be hinged to the inner surface of the top wall 61 or the side wall 62.
[0128] like Figure 6 As shown, the swing member 41 can be fixedly connected to the scraper member 20 through the mounting base 80.
[0129] Furthermore, the swing element 41 and the mounting base 80 can be manufactured using an integral molding process, which helps to improve the mechanical strength of their connection.
[0130] Alternatively, the one-piece molding process can be injection molding. In this case, both the swing component 41 and the mounting base 80 can be made of plastic material.
[0131] like Figure 6 As shown, the two ends of the swing member 41 have raised portions 41d relative to the middle portion. That is, the swing member 41 has a "U"-shaped structure with raised ends and a concave middle. The two raised ends of the "U"-shaped structure can be fixedly connected to the scraper member 20 through the scraper member mounting seat 80 respectively.
[0132] The swing member 41 is hinged to the inner surface of the base 10. This application does not limit how the swing member 41 is hinged to the inner surface of the base 10. For example, a pivot can be provided on the side wall of the swing member 41, and the pivot can be rotatably connected to the pivot mounting seat on the inner surface of the base 10, thereby realizing the hinge between the two.
[0133] like Figure 7 , 8 As shown in this embodiment, the swing member 41 has a hinge hole 41a in the middle, and a hinge shaft 41b is fixedly disposed in the hinge hole 41a. A hinge seat 12 is disposed on the inner surface of the base 10, and the hinge seat 12 extends into the hinge hole 41a and is rotatably connected to the hinge shaft 41b. At this time, a mounting hole is formed on the hinge seat 12, and the hinge shaft 41b can be inserted into the mounting hole and can rotate relative to the mounting hole. Through the above arrangement, the bottom surface of the swing member 41 is closer to the inner surface of the base 10, thereby making the swing of the swing member 41 more controllable.
[0134] Figure 9 This is a schematic diagram of the structure of the transmission component 40 provided in the embodiment of this application. Figure 10 This is a partial structural schematic diagram of the transmission assembly 40 provided in the embodiments of this application. Figure 11 This is an exploded view of a portion of the structure of the transmission assembly 40 provided in the embodiments of this application. Figure 12 yes Figure 3 A cross-sectional schematic diagram from the perspective of AA.
[0135] like Figure 6-12 As shown, the base 10 has a connecting through hole 13 that penetrates the outer surface 11, and the scraping device 100 also includes a connector 42 movably disposed within the connecting through hole 13. The transmission assembly 40 also includes a translational member 43 movably disposed within the base 10.
[0136] Friction member 30 is connected to transmission assembly 40 via connector 42. At this time, friction member 30 drives translation member 43 to move backward relative to outer surface 11 in the direction of travel via connector 42, and translation member 43 further drives oscillating member 41 to oscillate.
[0137] In other words, the friction member 30 drives the translation member 43 to move through the connecting member 42. The translation member 43 is restricted to moving only in the horizontal direction and cannot move in the vertical direction. Under the action of the friction member 30, the translation member 43 can move backward relative to the outer surface 11 in the direction of travel. The translation member 43 further transmits this movement to the swing member 41 to drive the swing member 41 to swing, thereby driving the scraping member 20 to move.
[0138] This application does not limit how the translation member 43 drives the swing member 41 to swing. The translation member 43 can directly drive the swing member to swing, or it can indirectly drive the swing member to swing through other components.
[0139] Optionally, the translating member 43 itself or other third-party components can press one side of the swing member 41, thereby driving the swing member 41 to swing.
[0140] Alternatively, the translational member 43 itself or other third-party components can lift (or support) one side of the swing member 41, thereby driving the swing member 41 to swing.
[0141] like Figure 6 , 8 As shown in the embodiment of this application, the two ends of the swing member 41 have raised portions 41d relative to the middle portion, and the translation member 43 moves backward to press the raised portions 41d on the rear side, thereby driving the swing member 41 to swing.
[0142] Here, "raised up" can also be understood as "protruding" or "bulging out", that is, the two ends of the swing member 41 protrude upward relative to the middle part, so as to be higher than the middle part.
[0143] At this time, the overall shape of the swing member 41 is "U" shaped. In other embodiments, the overall shape of the swing member 41 can be any shape with both sides protruding from the middle, such as "V", "W", or wave.
[0144] In this embodiment, the lower surface of the translational member 43 is slidably connected to the upper surface of the swing member 41. With this configuration, the swing member 41 can support the translational member 43 to limit its movement, thereby making the movement of the translational member 43 more controllable.
[0145] Specifically, such as Figure 9-11 As shown, the translational member 43 is divided into a left part and a right part. The left part is connected to the friction member 30 through the connector 42, and the right part is slidably connected to the swing member 41. The shape of the right part is adapted to the shape of the swing member 41 and is also "U" shaped, and is correspondingly set inside the opening of the "U" shaped swing member 41.
[0146] At this time, in the non-pressed state (i.e., free state), the translation member 43 is supported on the swing member 43 and is located in the middle part of the swing member 43. The side wall of the translation member 43 does not press the raised part 41d, so the swing member 43 does not swing.
[0147] In the pressed state, the friction member 30 drives the translation member 43 to move backward relative to the swing member 41. The rear side wall of the translation member 43 (specifically, the rear side wall of the right side of the translation member 43) presses against the surface of the raised part 41d, causing the swing member 43 to swing, the rear end to be pressed down, and the front end to be raised, thereby causing the scraper member 20 to move.
[0148] Alternatively, in other embodiments, the translational member 43 and the swing member 41 may be rolled together. In this case, a roller may be provided on the mating surface of one of them, and a guide rail adapted to the roller may be provided on the other.
[0149] Alternatively, in other embodiments, in the non-pressed state (i.e., free state), the translational member 43 and the swinging member 41 may not be connected (or in contact), and the swinging member 41 is pressed only after the two undergo relative displacement.
[0150] At this time, the lower surface of the translation member 43 can abut against the inner surface of the base 10, so that the right side of the translation member 43 is "suspended" above the swing member 41, and the lower surface of the right side of the translation member 43 does not contact the upper surface of the swing member 41.
[0151] In this embodiment, the translation member 43 is disposed above the swing member 41 and the two are slidably connected. Since the swing member 41 is hinged to the inner surface of the base 10, the swing member 41 has a "U" shaped structure with both ends raised and the middle recessed. The translation member 43 can move back and forth in the horizontal direction. Thus, when the translation member 43 moves toward one end of the swing member 41, it can press that end, thereby driving that end of the swing member 41 to be pressed down and the other end to be raised.
[0152] Specifically, when the wiping device 100 moves to the right, the friction element 30 moves to the left due to the frictional force to the left. At this time, the connecting element 42 drives the translational element 43 to move to the left. The translational element 43 presses down on the left end of the swing element 41, causing the left end of the swing element 41 to be pressed down and the right end to be lifted up. This further drives the left end of the wiping element 20 to be pressed down close to the glass surface to perform wiping work, and drives the right end of the wiping element 20 to be lifted away from the glass surface and not to work.
[0153] In this embodiment, the translation member 43 or the swing member 41 is provided with a sliding rib 43a, and the translation member 43 and the swing member 41 are slidably connected by the sliding rib 43a.
[0154] Specifically, in order to reduce friction and allow smooth sliding between the translational member 43 and the oscillating member 41, a sliding rib 43a is provided on the lower surface of the translational member 43 (i.e., the lower surface of the right side portion). The lower surface of the translational member 43 and the upper surface of the oscillating member 41 are slidably connected by the sliding rib 43a. Figure 10 , 11 As shown, the sliding rib 43a can be set at the two corners of the lower surface of the right side portion.
[0155] In other embodiments, the sliding rib 43a can also be provided on the upper surface of the swing member 41 to achieve a similar effect, and this application does not limit this.
[0156] like Figure 9-12 As shown, the friction element 30 is fixedly mounted on the connector 42. The connector 42 is connected to the translational element 43 via an elastic element 44, allowing the connector 42 to elastically extend and retract relative to the translational element 43 in a direction perpendicular to the outer surface 11. This configuration allows for timely compensation after wear occurs in the friction element 30, ensuring more reliable contact between the friction element 30 and the glass surface to generate friction.
[0157] like Figure 11 , 12 As shown, the connector 42 includes a mounting plate 42a, abutment posts 42b, and limiting hooks 42c. The friction member 30 is fixedly mounted on the outer side of the mounting plate 42a, and the two abutment posts 42b and the limiting hooks 42c are fixedly mounted on the inner side of the mounting plate 42a.
[0158] The translational member 43 has a snap-fit hole 43c and two abutment holes 43b on its side facing the connector 42. The two abutment pins 42b extend into the two abutment holes 43b respectively. An elastic element 44 is provided between the front end of the abutment pin 42b and the top wall of the abutment hole 43b. For example, the elastic element 44 can be a spring.
[0159] The limiting hook 42c engages with the engaging hole 43c, thus compressing the elastic element 44. The hook portion of the limiting hook 42c restricts its movement outward from the engaging hole 43c, keeping the elastic element 44 constantly compressed. Simultaneously, the engaging hole 43c has an accommodating space, preventing the hook portion from further inward movement. When compressed, the hook portion moves inward, allowing the entire connecting member 42 to extend and retract relative to the translational member 43.
[0160] When the friction element 30 is displaced relative to the base 10, the abutment post 42b acts as a limit, that is, when the friction element 30 moves to the maximum displacement position, the abutment post 42b abuts against the wall of the connecting through hole 13. It is easy to understand that at this time, the double scraping element 20 is also moved to the preset position.
[0161] Optionally, the connector 42 can move along the length of the connecting through hole 13, the length being parallel to the direction of travel.
[0162] Figure 13 This is a connection diagram of the directional component 50 provided in an embodiment of this application. For example... Figure 9 , 13 As shown, the scraping device 100 also includes a directional component 50, which is used to orient the displacement of the translational member 43 so that the translational member 43 and the oscillating member 41 remain reliably connected. The directional component 50 can control the displacement of the translational member 43 so that the translational member 43 does not detach from the oscillating member 41, thereby improving the performance of the scraping device 100.
[0163] like Figure 13 As shown in this embodiment, the orientation component 50 includes a roller 51 and a guide rail 52 that cooperate with each other; the roller 51 is rotatably mounted on the upper surface of the translational member 43 via a rotating shaft, and the guide rail 52 is fixedly mounted on the inner surface of the top wall 61. The roller 51 can roll along the guide rail 52.
[0164] In other embodiments, the positions of the roller 51 and the guide rail 52 can be interchanged. The roller 51 can be rotatably mounted on the inner surface of the top wall 61, and the guide rail 52 can be fixedly mounted on the upper surface of the translation member 43, achieving a similar effect as described above.
[0165] This application does not limit the specific arrangement of the orientation component 50, as long as it can achieve the aforementioned displacement orientation function. For example, in other embodiments, the orientation component may include mutually compatible sliding pins and sliding grooves. In this case, a mounting wall can be provided at the edge of the base 10, the sliding pin can be provided on one of the inner surface of the mounting wall and the side surface of the translational member, and the sliding groove can be provided on the other of the inner surface of the mounting wall and the side surface of the translational member.
[0166] like Figure 3-11As shown in this embodiment, the friction element 30 includes two friction elements 30, which are disposed on opposite sides of the outer surface 11. Each friction element 30 is connected to the double scraping element 20 via a transmission assembly 40. The two translational elements 43 in the two transmission assemblies 40 are fixedly connected by a synchronizing element 70 to achieve synchronous movement of the two translational elements 43. This arrangement not only achieves synchronous movement of the two translational elements 43 but also facilitates better control of the displacement of the translational elements 43, and promotes a reliable connection between the translational elements 43 and the oscillating element 41.
[0167] like Figure 10 , 11 As shown in the embodiment of this application, the synchronizing member 70 is in the shape of a frame, with the two sides fixedly connected to the translation member 43 respectively. In other embodiments, the synchronizing member 70 may also be in other shapes, such as an "X" shape, etc., which is not limited in this application.
[0168] The two translational components 43 and the synchronizing component 70 are manufactured using a one-piece molding process. This arrangement improves the stability of the mechanical connection. For example, this one-piece molding process can be injection molding.
[0169] At this time, the translational member 43 and the synchronizing member 70 can form a frame-like structure, which can slide relative to each other on the two swinging members 41.
[0170] like Figure 6 , 8 As shown in the embodiment of this application, two swing members 41 are also disposed on opposite sides of the base 10, and each swing member 41 is connected to the double scraper member 20. Through the above arrangement, the scraper member 20 can be better controlled in raising and lowering.
[0171] Optionally, the two swing members 41 and the two scraper mounting bases 80 can be manufactured using a one-piece molding process to improve the stability of the mechanical connection. For example, this one-piece molding process can be injection molding.
[0172] like Figure 1 , 5As shown in Figure 13, in this embodiment of the application, the scraping device 100 further includes a winding device 90, which includes a knob 91, a winding shaft 92, a wire-blocking cylinder 93, and a safety rope 94. The knob 91 includes a connecting block that passes through the top wall 61 and is fixedly connected to the internal winding shaft 92. The winding shaft 92 is surrounded by the wire-blocking cylinder 93. The safety rope 94 is wound around the winding shaft 92, with one end fixedly connected to the winding shaft 92, and the other end passing through a first wire outlet hole 95 on the wire-blocking cylinder 93 and a second wire outlet hole 96 on the side wall 62 before connecting to a fixing ring (not shown in the figure). In use, the scraping device 100 can be placed on the outside of the glass, and the user can simply fasten the fixing ring.
[0173] Furthermore, the lower end of the winding spool 92 is also provided with a line-blocking part, which is arranged close to the line-blocking cylinder 93, thereby effectively confining the safety rope 94 within the space formed by the line-blocking part and the line-blocking cylinder 93.
[0174] like Figure 5 As shown in this embodiment, the scraping device 100 further includes a magnetic attraction device 99, which includes magnets 99a, magnet mounting bases 99b, and magnet fixing frames 99c. There can be four magnets 99a, all fixedly mounted on the magnet mounting bases 99b. The magnet mounting bases 99b can be made of thick iron sheets or steel sheets, etc., to securely mount and fix the magnets 99a. The magnet fixing frames 99c also fix the magnets 99a, preventing relative displacement of the magnets 99a in the horizontal direction.
[0175] Alternatively, in other embodiments, an electromagnet may be provided in the scraping device 100 to replace the magnetic attraction device 99, or a magnetic material such as an iron block or steel block may be provided to replace the magnet 99a (in which case mutual attraction can be achieved by providing a magnet on the opposite end of the glass scratch). This application does not limit this.
[0176] The top cover 60 is detachably mounted on the base 10. This application does not limit the connection method between the top cover 60 and the base 10. For example... Figure 7 , 13 As shown in this embodiment, multiple screw holes 16 are provided on the base 10, and correspondingly multiple nut posts 63 are provided on the inner surface of the top cover 60. During installation, it is only necessary to let the screw pass through the screw holes 16 and then screw it into the nut post 63.
[0177] like Figure 7 As shown, the base 10 also has a wiping material mounting hole 15, through which the wiping material 14 can be mounted and fixed on the outer surface 11. Optionally, the wiping material mounting hole 15 can be a threaded hole or a snap-fit hole, etc.
[0178] like Figure 7 As shown, a magnet limiting post 17 is also provided on the base 10. The magnet mounting base 99b can be provided with a corresponding through hole so that the magnet limiting post 17 can be inserted into the through hole, thereby achieving the function of positioning and fixing the magnet mounting base 99b.
[0179] Figure 14 This is a schematic diagram of another example of the scraping device 100 provided in this application embodiment. Compared with the previous embodiment, in this embodiment, the friction element 30 is a suction cup, which is fixedly installed on the connecting element 42. During scraping, the suction cup can firmly adhere to the glass surface. Under the action of this adhesion force, friction can also be generated between the suction cup and the glass surface, thereby driving the double scraping elements 20 to move.
[0180] Figure 15 This is a schematic diagram of another example of the scraping device 100 provided in the embodiments of this application. Figure 16 yes Figure 15 A cross-sectional diagram from the perspective of the middle BB.
[0181] Compared to the aforementioned embodiments, in this embodiment, the friction element 30 is a roller rotatably connected to the connector 42. In this embodiment, the friction element 30 is a roller that can rotate relative to the connector 42 to a certain extent. The roller can roll or slide against the glass surface, thereby generating frictional force. This frictional force is further transmitted to the connector 42, thereby driving the double scraper 20 to move.
[0182] Specifically, a mounting groove 42d is formed on the outer surface of the connector 42, and the roller is rotatably mounted in the mounting groove 42d via a rotating shaft. It should be understood that the upper part of the roller should protrude from the mounting groove 42d to allow friction with the glass surface. The mounting groove 42d has an arc-shaped bottom surface. In the free state, the roller is located in the middle of the mounting groove 42d and directly opposite the apex of the arc-shaped bottom surface. At this time, there may be a gap between the roller and the apex, or the roller may abut against the apex. Figure 15 , 16 As shown, a groove 42e can be opened on the side of the connector 42, and the roller shaft is slidably disposed in the groove 42e. When subjected to friction, the roller undergoes horizontal displacement. At this time, the roller abuts against the arc-shaped bottom surface of the mounting groove 42d, and the roller cannot continue to roll. At this time, the friction can be transmitted from the roller to the connector 42 through the arc-shaped bottom surface.
[0183] Figure 17 This is a schematic diagram of another example of the scraping device 100 provided in the embodiments of this application. Figure 17 As shown, the main difference between this embodiment and the previous embodiment lies in the connection relationship between the translation member 43 and the swing member 41.
[0184] like Figure 17 As shown, in this embodiment, the translation member 43 is provided with a first sliding pin 43d, and the swing member is provided with an inclined guide groove 41c. The first sliding pin 43d is slidably disposed in the inclined guide groove 41c. The translation member 43 moves backward to press the swing member 41 through the inclined guide groove 43, thereby driving the swing member 41 to swing.
[0185] Specifically, the translation member 43 is provided with a first sliding pin 43d on the side facing the swing member 41, and the swing member 41 is provided with a "V"-shaped inclined guide groove 41c on the side facing the translation member 43. The first sliding pin 43d is slidably disposed in the inclined guide groove 41c so that the translation member 43 can drive the swing member 41 to swing.
[0186] In the free state, the first sliding pin 43d can be located at the bottom of the "V"-shaped inclined guide groove 41c. When the scraping device 100 moves to the right to scrape the glass surface, under the action of friction, the translation member 43 moves backward, which causes the first sliding pin 43d to move backward relative to the inclined guide groove 41c. At this time, since the translation member 43 can only perform translation, the first sliding pin 43d exerts pressure on the lower side wall of the inclined groove on the rear side. Under the pressure of the first sliding pin 43d, the swing member 41 swings to the left, the left scraping member 20 is dropped to get close to the glass surface to perform scraping work, and the right scraping member 20 is lifted to move away from the glass surface and not work.
[0187] Alternatively, the inclined guide groove 41c can also be U-shaped.
[0188] Optionally, there can be two first sliding pins 43d and two alternating inclined guide grooves 41c. The first sliding pins 43d and the inclined guide grooves 41c correspond one-to-one. The inclined guide grooves 41c are inclined upwards from the inside out, and each has a horizontally arranged clearance groove connected to its inner side. When the first sliding pin 43d moves backward relative to the inclined guide groove 41c, the rear first sliding pin 43d presses against the lower side wall of the rear inclined guide groove 41c, and the front first sliding pin 43d slides into the horizontally arranged clearance groove.
[0189] Optionally, such as Figure 17 As shown, multiple smooth protrusions 43e are provided on the contact surface between the translation member 43 and the base 10. This reduces the friction between the translation member 43 and the base 10, facilitating relative sliding between them.
[0190] On the other hand, this application also provides a scraping component 1000. Figure 18 This is a schematic diagram of the structure of the scraping assembly 1000 provided in an embodiment of this application. Figure 18As shown, the scraping assembly 1000 includes a first scraping device 200 and a second scraping device 300 that can be attracted to each other, wherein at least one of the first scraping device 200 and the second scraping device 300 is the scraping device 100 provided in any of the foregoing embodiments.
[0191] Furthermore, the scraping assembly 1000 also includes an anti-sucking barrier 400, and the first scraping device 200 is connected and fixed to the second scraping device 300 through the anti-sucking barrier 400.
[0192] Optionally, the first scraping device 200 is provided with a wire winding device, and the second scraping device 300 is provided with a magnetic adjustment device.
[0193] Optionally, the first scraping device 200 and the second scraping device 300 are provided with magnets of different polarities.
[0194] Optionally, one of the first scraping device 200 and the second scraping device 300 is provided with a magnet, and the other is provided with a magnetic material such as an iron block or a steel block.
[0195] Optionally, the first scraping device 200 and the second scraping device 300 are attracted to each other by an electromagnet.
[0196] Optionally, at least one of the first scraping device 200 and the second scraping device 300 is further provided with a travel motor. The travel motor is used to drive the scraping device to move.
[0197] Since the scraping assembly 1000 adopts the scraping device 100 provided in the above embodiment, the scraping assembly 1000 also has the same technical effect as the aforementioned scraping device 100, which will not be described in detail here.
[0198] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
