In a first aspect, an embodiment of the present invention provides a scraping device, including: a support 10, and a control assembly 16, a sensing assembly, a driving assembly 11, a swinging mechanism 13 and at least two scraping assemblies 14 which are arranged on the support 10; the control assembly 16 is electrically connected with the sensing assembly and the driving assembly 11 respectively; the swinging mechanism 13 is hinged with the support 10, and at least two scraping assemblies 14 are respectively connected with two ends of the swinging mechanism 13 and are positioned on two opposite sides of the support 10; the sensing assembly is used for acquiring the moving direction of the scraping device on the scraping surface 24; the control assembly 16 is used for controlling the driving assembly 11 to drive the swinging mechanism 13 to swing according to the moving direction, so that the scraping assembly 14 positioned at the front side of the moving direction is far away from the scraping surface 24, and the scraping assembly 14 positioned at the rear side of the moving direction is close to the scraping surface 24.

Illustratively, as shown in fig. 1, a sensing assembly, a control assembly 16, a drive assembly 11, a swing mechanism 13, and at least two wiper assemblies 14 are disposed on the frame 10. Wherein, the sensing assembly is electrically connected with the control assembly 16, and the control assembly 16 is electrically connected with the driving assembly 11. Correspondingly, the drive assembly 11 is drivingly connected to the oscillating mechanism 13, so as to drive the movement of at least two wiper assemblies 14 arranged on the oscillating mechanism 13.

In some embodiments, at least two of the wiping assemblies 14 are positioned on opposite sides of the frame 10 to facilitate efficient removal of soil as the wiping device is moved across the wiping surface 24, wherein the wiping assemblies 14 near the rear side in the direction of movement are in constant contact with the wiping surface 24. The oscillating mechanism 13 and the scraping assemblies 14 can be arranged in a manner as shown in fig. 2, the two scraping assemblies 14 are arranged oppositely, and the oscillating mechanism 13 can be perpendicular to the two scraping assemblies 14 and fixedly connected with the two scraping assemblies 14. The swinging mechanism 13 is shown in fig. 2 as two parallel connecting beams, and in other embodiments, the number and form of the connecting beams are not limited. For example, the number of the grooves may be 1, 3, 4, etc., and the grooves may intersect each other to form an X-shape, or may be W-shaped, etc. The oscillating mechanism 13 and the scraping assembly 14 can be integrally formed, which is beneficial to improving the mechanical strength of the connection between the two. Of course, it may be processed separately. When the swing mechanism 13 and the scraping assembly 14 are not integrally formed, they can be connected by means of screws, snaps, glue, etc. so as to facilitate quick removal and replacement when needed.

The sensing component is electrically connected with the control component 16, and the control component 16 is electrically connected with the driving component 11, that is, the sensing component, the control component and the driving component can transmit electric signals on the basis of supplying the basic power supply 15. The power supply 15 may be directly provided on the bracket 10 as shown in fig. 1, or may be provided on the bracket 10 with a power supply 15 interface connected to the three, and the power supply is connected to an external power supply through a wire.

A sensing assembly located on the carriage 10 can obtain a sense of the direction of movement of the scraping device across the scraping surface 24 as the scraping device is moved relative to the scraping surface 24. The control assembly 16 controls the driving assembly 11 to drive the swinging mechanism 13 to swing according to the moving direction of the scraping device, namely the traveling direction, so that the scraping assembly 14 positioned at the front side of the moving direction is lifted upwards, namely moves away from the scraping surface 24, and at the moment, the scraping assembly 14 positioned at the front side of the moving direction is separated from the scraping surface 24 and is not in contact with the scraping surface 24 in an inactive state. Meanwhile, due to the movement of the swing mechanism 13, the scraping component 14 located at the rear side in the moving direction is driven to fall downwards, i.e. to move towards the direction close to the scraping surface 24, at this time, the scraping component 14 located at the rear side in the moving direction is in a working state in contact with the scraping surface 24, so as to clean the scraping surface 24 along with the movement of the scraping device, for example, in combination with the cleaning component 30 in the subsequent embodiment, the cleaning or wiping of the scraping component 14 is facilitated by the contact wetting of the cleaning component 30. The wiping assembly 14 can be telescoping toward or away from the wiping surface 24, and can be rotatable to achieve a perpendicular or parallel orientation relative to the wiping surface 24.

In addition, the scraping device can also comprise a top cover 104, and the top cover 104 further comprises a top plate 17 and side plates, wherein the side plates are arranged around the circumference of the top plate 17 so as to form a groove-shaped structure in an enclosing manner. The top cover 104 can be fixedly covered on the support frame 10, thereby forming a hollow accommodating cavity. Illustratively, the control assembly 16, the drive assembly 11, and the oscillating mechanism 13 may be disposed within the receiving cavity.

In some embodiments, the scraping device moves to scrape the scraping surface 24, which may be manually moved by a user, or the scraping device is driven by a driver, such as a motor, an air cylinder, etc., without limitation. When the walking stick is driven by the driver, automatic walking can be realized.

In this embodiment, the scraping surface 24 may be a glass surface, a desktop surface, a wall surface, a floor surface, a blackboard surface, etc., which is not limited in this application.

The control assembly 16 is housed within the support 10. The control component 16 may be a Micro Controller Unit (MCU), or other general purpose Processor, a Central Processing Unit (CPU), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), an off-the-shelf Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, a discrete hardware component, etc., without limitation. The power source 15 may be a lithium battery, an alkaline battery, a nickel-metal hydride battery, etc., without limitation.

In addition, in order to further improve the automation degree of the scraping device, a sensor, an intelligent control system and the like can be correspondingly arranged, so that the scraping surface 24 can be scanned, and a cleaning path can be automatically established.

As shown in fig. 2, the oscillating mechanism 13 may include a connecting beam, and at least two scraping assemblies 14 are connected to both ends of the connecting beam, respectively, and two or more connecting beams may be provided for improving stability. At least two scraping assemblies 14 are respectively connected with two ends of the swinging mechanism 13 in a fixed connection mode, a hinged connection mode and the like. Meanwhile, the number of the scraping assemblies 14 arranged at each end of the swinging mechanism 13 may be 1, 2, 3, 4, etc. as shown in fig. 3, and the number arranged at the two ends may be equal or unequal, which is not specifically limited in this embodiment. In order to realize that when the scraping device moves, the swing mechanism 13 drives one end of the scraping assemblies 14 arranged at the two ends of the swing mechanism 13 to be in contact with the scraping surface 24 and the other end of the swing mechanism to be far away from the scraping surface 24, as shown in fig. 2 and 9, the swing mechanism 13 can be hinged to one side of the support 10 close to the top cover 104 and can swing relative to the support 10, so that the swing mechanism 13 can drive the scraping assemblies 14 to swing, namely, the scraping assemblies 14 at one end of the swing mechanism 13 are close to the scraping surface 24 and the scraping assemblies 14 at the other end of the swing mechanism 13 are far away from the scraping surface 24 while swinging. Specifically, a swing mechanism mounting groove 102 may be formed in the bracket 10, and in cooperation, a rotating shaft is disposed on the swing mechanism 13, and the rotating shaft is rotatably mounted in the swing mechanism mounting groove 102, so as to realize the hinge joint between the two. In order to realize more stable and controllable swing of the swing mechanism 13, a hinge hole may be further formed in the middle of the swing mechanism 13 (when the swing mechanism 13 includes a connection beam, the middle of the connection beam may be formed), a rotation shaft is fixedly disposed in the hinge hole, a swing mechanism mounting groove 102 is disposed on the inner surface of the bracket 10, the rotation shaft is embedded in the mounting groove, and the swing mechanism can rotate relative to the mounting groove. The driving assembly 11 is in driving connection with the swinging mechanism 13, and may be in contact driving or non-contact driving, as long as the driving assembly 11 can drive the swinging mechanism 13 to swing in a specified direction by acting force when necessary.

When the scraping device moves, the sensing assembly acquires the moving direction of the sensing assembly, the control assembly 16 sends a driving instruction to the driving assembly 11 according to the moving direction information, the driving assembly 11 correspondingly drives the swing mechanism 13 to swing according to the driving instruction, so that the end, located on the front side of the moving direction, of the swing mechanism 13 is far away from the scraping surface 24, meanwhile, the end, located on the rear side of the moving direction, of the driving mechanism is close to the scraping surface 24, the scraping assemblies 14 are respectively arranged at two ends of the swing mechanism 13, and therefore the fact that the scraping assemblies 14 located on the front side of the moving direction are far away from the scraping surface 24 and the scraping assemblies 14 located on the rear side of the moving direction are close to the scraping surface 24 is achieved. When the moving directions of the scraping devices are opposite, the corresponding driving assemblies 11 drive the swinging mechanisms 13 to swing in opposite directions, so that the scraping assemblies 14 at two ends of the swinging mechanisms 13 correspondingly switch the working states.

As shown in fig. 4, when the scraping apparatus moves along the direction indicated by the arrow in fig. 4 (i.e., from right to left), the sensing element captures the moving direction from right to left, and the control element 16 correspondingly controls the driving element 11 to drive the swinging mechanism 13 to swing clockwise, at this time, the scraping element 14 on the right side is close to the scraping surface 24 and contacts the scraping surface 24, and the scraping element 14 on the left side is far from the scraping surface 24 and separates from the scraping surface 24. With continued movement of the scraping device, the scraping assembly 14 on the right side begins to scrape.

As shown in fig. 8, when the scraping apparatus moves in the direction indicated by the arrow in fig. 8 (i.e., from left to right), the sensing component acquires the moving direction from left to right, and the control component 16 correspondingly controls the driving component 11 to drive the swinging mechanism 13 to swing counterclockwise, at this time, the scraping component 14 on the right side starts to lift up from the contact scraping surface 24, i.e., is far away from the scraping surface 24, until it is separated from the scraping surface 24. The scraping assemblies 14 on the left side move downwards from the position where the scraping assemblies do not contact the scraping surface 24, namely, the scraping assemblies are close to the scraping surface 24 until the scraping assemblies contact the scraping surface 24, and at the moment, along with the switching of the moving direction of the scraping device, the corresponding scraping assemblies 14 on the two ends of the swinging mechanism 13 are correspondingly switched into the working state. As the scraping device continues to move, the scraping assembly 14 on the left side begins to scrape.

In some embodiments, the drive assembly 11 may be a rotary motor. The output mode of the rotating electric machine, i.e., the output shaft thereof, is a rotational output. The output shaft of the rotating motor is in transmission connection with the swinging mechanism 13, so that the swinging mechanism 13 is driven to swing relative to the bracket 10. Specifically, the output shaft of the rotating motor can be directly connected with the hinged shaft of the swing mechanism 13, and can also be in transmission connection through intermediate mechanisms such as gears, racks, synchronous belts, connecting rods and the like, and the application does not limit the specific transmission form.

When the scraping device moves, the moving direction of the scraping device is sensed and obtained through the sensing assembly, the control assembly 16 controls the rotating motor to rotate, and then the swinging mechanism 13 is driven to swing relative to the support 10, so that the scraping assembly 14 located on the front side in the moving direction is separated from the scraping surface 24, and the scraping assembly 14 located on the rear side in the moving direction is in contact with the scraping surface 24. When the moving direction of the scraping device is switched, the corresponding control component 16 switches the current direction of the rotating motor, so that the rotating direction of the output shaft of the rotating motor is changed, and the switching of the swinging direction of the swinging mechanism 13 is realized.

In some embodiments, the drive assembly 11 may include at least two rotary motors. Thereby improving the stability of the swing mechanism 13. Taking two rotating electric machines as an example, the two rotating electric machines are respectively arranged at two ends of the swinging mechanism 13, and output shafts of the rotating electric machines are respectively positioned at two sides of a hinged shaft of the swinging mechanism 13 and the bracket 10. An eccentric part is arranged on the output shaft of each rotating motor, so that the output shaft of each rotating motor is correspondingly abutted against the two ends of the swinging mechanism 13 through the eccentric parts. The eccentric directions of the eccentric parts at the two ends of the swing mechanism 13 should be different, so that the swing mechanism 13 can be correspondingly pushed to swing when necessary. The eccentric part can be a swing rod fixedly arranged on an output shaft of the rotating motor, and can also be an eccentric wheel, and the shape of the eccentric wheel can be an elliptical eccentric wheel, a sector eccentric wheel, a water drop eccentric wheel and the like. The embodiment of the present application is not particularly limited thereto.

In some embodiments, the drive assembly 11 may also be a linear motor. Illustratively, when the number of the linear motors is one, the output shaft of each linear motor can be hinged to one of the two ends of the swing mechanism 13, and the control assembly 16 controls the extension and retraction of the output shaft of the linear motor to drive the swing mechanism 13 and the hinged side of the swing mechanism to lift up or fall down, and correspondingly, the other end of the swing mechanism 13 is driven to move oppositely. When the number of the linear motors is at least two, taking two as an example, the two linear motors are respectively arranged at two sides of a hinge shaft hinged by the swing mechanism 13 and the bracket 10, and meanwhile, output shafts of the two linear motors can be respectively hinged with two ends of the swing mechanism 13, so that one of the two linear motors is controlled to extend and the other one of the two linear motors is controlled to retract through coordination of the control assembly 16, and in order to ensure the stability of the mechanism, the extension amount and the retraction amount should be correspondingly complemented. Furthermore, a deformation element may also be provided in order to compensate for errors occurring in both. The hinge may be a direct hinge of the output shaft of the linear motor and the swing mechanism 13, or a hinge via a third connecting member, such as a rope, a connecting rod, an elastic member, etc. When the hinge is a direct hinge, the portion of the output shaft of the linear motor that is hinged to the swing mechanism 13 should be deformed to compensate for the lateral displacement of the swing mechanism 13 during rotation.

In some embodiments, the driving assembly 11 may also be an electromagnet 21. The electromagnet 21 may be composed of an iron core and a coil, and the control module 16 controls the energization state of the coil, thereby realizing the switching of the presence or absence of the attraction force of the electromagnet 21. Correspondingly, the control component 16 controls the current direction of the coil, so as to realize the switching of the polarity of the electromagnet 21. At least one counterpart 22 can also be provided on the pivoting mechanism 13. By energizing or switching the polarity of the electromagnet 21, the mating member 22 is driven to move closer to or away from the electromagnet 21, and the swing mechanism 13 is driven to swing. The engaging member 22 and the electromagnet 21 can form a magnetic attraction engagement, and the engaging member 22 can be a metal capable of being attracted by the electromagnet 21, such as iron, nickel, cobalt, etc., as required. Or may be a magnet with a polarity, without limitation. Preferably, the engaging member 22 is disposed at a portion where the swing mechanism 13 is connected to the wiping assembly 14 to increase the torque, so that the electromagnet 21 can be driven with a smaller power, and when the power is supplied by the internal power supply 15, the power consumption is reduced, and the endurance is increased.

In still another embodiment, referring to fig. 4, the swing mechanism 13 is two independent supporting mechanisms, namely a first supporting mechanism 131 and a second supporting mechanism 132. The first support mechanism 131 and the second support mechanism 132 are movably connected to the two wiping assemblies 14, respectively, such that the two wiping assemblies 14 are movable in a vertical direction along the first support mechanism 131 and the second support mechanism 132. The two scraping assemblies 14 are respectively provided with a magnetic assembly 23, and an electromagnet 21 is arranged opposite to the magnetic assembly 23 in the vertical direction.

In some embodiments, when one electromagnet 21 is provided, it is correspondingly disposed on one side of the swinging mechanism 13, that is, the electromagnet 21 corresponds to one end of the swinging mechanism 13 where the engaging element 22 is disposed, and when the control component 16 controls the polarity of the electromagnet 21 to be the same as that of the engaging element 22, the electromagnet 21 and the engaging element 22 generate a repulsive force, and at this time, one end of the swinging mechanism 13 where the engaging element 22 is disposed moves away from the electromagnet 21, that is, toward the direction close to the scraping surface 24, and correspondingly, the other end of the swinging mechanism 13 moves toward the direction away from the scraping surface 24. When the moving direction is switched, the control component 16 switches the current direction of the coil, at this time, the polarity of the electromagnet 21 is switched to be different from that of the mating member 22, and the electromagnet 21 and the mating member 22 generate an adsorption force, at this time, one end of the swing mechanism 13, which is provided with the mating member 22, is close to the electromagnet 21, i.e., moves in a direction away from the scraping surface 24, and correspondingly, the other end of the swing mechanism 13 moves in a direction close to the scraping surface 24.

In some embodiments, the sensing assembly includes a friction member and a sensor. Wherein the sensor is electrically connected to the control assembly 16. The sensor is arranged in correspondence with the friction member so that it can pick up the direction of movement of the friction member, the direction of movement of the scraping device being obtained by the fact that the direction of movement of the friction member is always opposite to the direction of movement of the scraping assembly 14. The friction member is movably disposed on the frame 10, and when the scraping device moves, the friction member contacts with the scraping surface 24 to generate a certain friction force, and the friction member is movably disposed on the frame 10, so that the friction member moves in a direction opposite to the moving direction of the scraping device under the driving of the friction force.

In order to provide sufficient friction between the friction member and the scraping surface 24 to drive the friction member relative to the scraping device, the friction member may have a sufficient coefficient of friction. The specific material of the friction member in this embodiment is not limited, and for example, the friction member may be made of plastic, silicone, rubber, resin, or the like. Of course, the friction member may be selected appropriately according to the specific material of the scraping surface 24 in order to expand the range of use of the scraping device and to make it more suitable for use.

A cleaning assembly 30 is provided below the frame 10 for wiping stains from the scraping surface 24. A through containing groove is arranged in the center of the cleaning component 30 which is arranged on the same side with the sensing component and is used for containing the sensing support 19, so that the distance between the sensing support 19 and the scraping surface 24 meets a preset distance interval. For example, when using a photosensor, the predetermined distance interval is 0.5mm to 1 mm. When a sensor such as a microswitch is used, the friction portion 251 is required to abut against the wiping surface 24, and the predetermined distance interval may be set to-0.1 mm to 0 mm.

The translation portion 28 is used for limiting the swing amplitude of the swing mechanism 13 when the swing mechanism 13 drives the scraping assembly 14 to swing, so as to prevent the swing amplitude of the swing mechanism 13 from being separated from the driving assembly mounting groove 103 due to overlarge swing amplitude.

When the displacement sensor is arranged corresponding to the friction part 251, it collects the displacement direction of the friction part 251 during movement, for example, the movement direction of the scraping device is obtained according to the position of the sensor itself by the distance from the friction part 251 to the sensor. Further, the moving direction of the wiper device may be acquired by acquiring the moving direction of the translation unit 28 by a displacement sensor so that the displacement sensor is provided corresponding to the translation unit 28.

Correspondingly, the first and second travel switches 26 and 27 may be provided at the maximum displacement of the friction portion 251 or the translation portion 28 in both directions, respectively. When the scraping device moves, the friction part 251 or the translation part 28 moves in the direction opposite to the moving direction, and when the scraping device moves to the maximum stroke, the first travel switch 26 or the second travel switch 27 is triggered by pressing, so that the control component 16 determines the moving direction according to the positions of the first travel switch 26 and the second travel switch 27, and further obtains the moving direction of the scraping device.

When the scraping device moves to the left, the friction part 251 will move to the right, when it moves to the maximum displacement, the travel switch on the right side is pressed, and the control assembly 16 obtains the moving direction of the scraping device through the position of the travel switch.

The friction portion 251 can be elastically extended and contracted in a direction perpendicular to the scraping surface 24 due to the elastic member. This kind of mode of setting can in time compensate after friction portion 251 takes place wearing and tearing for friction portion 251 is more reliable carries out the butt with scraping face 24, in order to produce sufficient frictional force, ensures that the response subassembly accurately acquires scraping device's moving direction.

At the same time, the friction force between the translation portion 28 and the top plate 17 can be reduced.
