[0027] Now, exemplary embodiments will be described more fully with reference to the drawings. However, the exemplary embodiments can be implemented in a variety of forms and should not be understood to be limited to the embodiments described herein. Rather, by providing these embodiments, the present application will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. In the drawings, the same reference numerals indicate the same or similar structures, and therefore detailed descriptions thereof will be omitted.

[0028] 1 to 10, the wiping mechanism 10 includes a wiping assembly 100 and a vibration assembly 200. The wiping assembly 100 includes a plurality of vibration plates 110, a link 120 is provided between two adjacent vibration plates 110, and the two adjacent vibration plates 110 can move synchronously via the link 120. At least one of the plurality of vibration plates 110 is provided with a connection part 1110. The vibration assembly 200 includes a vibration device and a vibration link 210, and one end of the vibration link 210 is connected to the vibration device and the other end is transmission-connected to the connection part 1110. The vibration assembly 200 is arranged to drive the vibration link 210 to reciprocate in a predetermined direction, and the vibration link 210 is arranged to reciprocate the plurality of vibration plates 110 when reciprocating in the predetermined direction.

[0029] In the wiping mechanism 10 provided by the present application, the wiping assembly 100 includes a plurality of vibrating plates 110, and the vibrating assembly 200 can drive the vibrating link 210 to reciprocate along a predetermined direction. Then, when the vibrating link 210 reciprocates along the predetermined direction, it can reciprocate the vibrating plate 110 at which the connection part 1110 is located. Since a link 120 is provided between two adjacent vibrating plates 110, when one vibrating plate 110 reciprocates, it can synchronously reciprocate the other vibrating plate 110 via the link 120. When the frequency of the reciprocating motion is relatively high, the reciprocating motion of the vibrating plate 110 can be considered as high-frequency vibration, which increases the vibration area of ​​the wiping mechanism and improves the cleaning efficiency and cleaning effect of the wiping mechanism.

[0030] 3 and 4, in one embodiment of the present application, the connection portion 1110 is a connecting groove, and the other end of the vibration link 210 is located in the connecting groove to realize the power transmission connection. Here, the vibration link 210 is arranged to abut against the side wall of the connecting groove when reciprocating in a predetermined direction, thereby causing the plurality of vibration plates 110 to reciprocate. The connecting groove facilitates assembly of the power transmission connection between the vibration link 210 and the vibration plates 110, and also facilitates installation, removal, and maintenance of the wiping mechanism 10.

[0031] 2 to 10 , the wiping assembly 100 includes two diaphragms, i.e., a first diaphragm 111 and a second diaphragm 112, which are identical in shape and size to each other or essentially identical to each other. Of course, the wiping assembly 100 may also include three, four, or more diaphragms 110, and this is not a limitation of the present application. Hereinafter, specific details of the wiping mechanism will be described in detail based on the wiping assembly 100 including two diaphragms.

[0032] 1 , the wiping mechanism further includes a bottom plate 300. The wiping assembly 100 and the vibrating assembly 200 are assembled to the bottom plate 300, the vibrating device is fixedly connected to the bottom plate 300, the plane in which the vibrating plate 110 reciprocates is parallel or essentially parallel to the plane in which the bottom plate 300 is located, the vibrating plate 110 and the bottom plate 300 are installed at a distance from each other, and the two vibrating plates 110 are connected to the bottom plate 300 via a position restriction structure, which forms a position restriction on the movement of the two vibrating plates 110 in the thickness direction of the bottom plate 300, thereby causing the vibrating plate 110 to reciprocate in a plane parallel or essentially parallel to the bottom plate 300.

[0033] The position restriction structure includes a position restriction arm and a position restriction portion, and a position restriction groove is formed in the position restriction portion. For example, position control arms are provided on both opposite sides of the first diaphragm 111 and the second diaphragm 112, and a position control portion is provided on the bottom plate 300, and the position control arms are located in the position control grooves to form position control against movement of the multiple diaphragms 110 in the thickness direction of the bottom plate 300; alternatively, position control portions are provided on both opposite sides of the first diaphragm 111 and the second diaphragm 112, and a position control arm is provided on the bottom plate 300, and the position control arm is located in the position control grooves to form position control against movement of the multiple diaphragms 110 in the thickness direction of the bottom plate 300; alternatively, a position control arm is provided on the first diaphragm 111, a position control portion is provided on the second diaphragm 112, and a position control portion and a position control arm are provided on the bottom plate 300, and the position control arm is located in the position control grooves to form position control against movement of the multiple diaphragms 110 in the thickness direction of the bottom plate 300. Here, the position restriction groove formed by the position restriction portion can accommodate the movement of the position restriction arm when the vibration plate 110 moves back and forth without interfering with the position restriction arm, and by adjusting the height of the position restriction groove in the thickness direction of the bottom plate 300, the size of the gap between the vibration plate 110 and the bottom plate 300 can be adjusted.

[0034] The position control arm may be flat and the position control portion may be rectangular and annular, and the position control arm and the position control portion form surface contact, and when the vibration plate 110 moves back and forth, the position control arm cooperates with the position control portion to form a guide action for the vibration plate 110, improving the stability and reliability of the vibration plate 110 during high-frequency vibration.

[0035] Here, in order to improve the strength of the position restriction structure, the position restriction arm and the diaphragm 110 or the bottom plate 300 are integrally formed, and the position restriction portion and the bottom plate 300 or the diaphragm 110 or the bottom plate 300 are integrally formed. Of course, the position restriction arm can be bonded, welded, engaged, riveted, etc. to the diaphragm 110 or the bottom plate 300, and the position restriction portion can be bonded, welded, engaged, riveted, etc. to the bottom plate 300 or the diaphragm 110 or the bottom plate 300, but this application is not limited thereto.

[0036] 2 to 6, two adjacent vibrating plates 110 reciprocate in opposite directions. By reciprocating two adjacent vibrating plates 110 in opposite directions, the vibration area of ​​the wiping mechanism is increased, improving the cleaning efficiency and cleaning effect of the wiping mechanism, and balancing the force caused by left and right vibration during vibration, improving the stability of the wiping mechanism.

[0037] A rotation shaft is provided on the bottom plate 300, and a through hole is provided at the middle position of the link 120. The link 120 is assembled to the rotation shaft on the bottom plate 300 via the through hole, thereby realizing rotation relative to the bottom plate 300.

[0038] The vibration plate 110 is provided with an accommodation space, and both ends of the link 120 are respectively located within the accommodation spaces of the two adjacent vibration plates 110. When one of the two adjacent vibration plates 110 moves back and forth, the link 120 is swung, thereby causing the other vibration plate 100 to move back and forth in the opposite direction via the link 120.

[0039] The accommodating space is a notch provided in the vibration plate 110, and as shown in Figures 4 and 5, a first notch 1111 is provided in the first vibration plate 111 and a second notch 1121 is provided in the second vibration plate 112, and both ends of the link 120 are located within the notches of the two adjacent vibration plates 110, respectively, and when one of the two adjacent vibration plates 110 moves back and forth, the side wall of the notch abuts against the link 120, causing the link 120 to oscillate, and further causing the other vibration plate 110 to move back and forth in the opposite direction via the link 120. For example, when the first diaphragm 111 reciprocates, the side wall of the first notch 1111 abuts against the link 120, causing the link 120 to swing, and the other end of the link 120 abuts against the second notch 1121 of the second diaphragm 112, causing the second diaphragm 112 to reciprocate in the opposite direction. Here, the accommodating space may also be a groove formed in the diaphragm 110, and the end of the link 120 may extend into the groove to move the diaphragm 110. The present application does not limit the specific structure of the accommodating space, and any accommodating space structure that can cooperate with the link 120 to achieve a transmission action is within the scope of protection of the present application.

[0040] For example, both ends of link 120 are located only in first notch 1111 and second notch 1121, respectively, and are not connected to first diaphragm 111 and second diaphragm 112. Acting force is transmitted between the ends of link 120 and first diaphragm 111 and second diaphragm 112 by abutment, thus facilitating assembly of first diaphragm 111, second diaphragm 112, and link 120, as well as facilitating maintenance.

[0041] For example, when both ends of the link 120 are located in the first notch 1111 and the second notch 1121, the both ends of the link 120 may be pivotally connected to the first diaphragm 111 and the second diaphragm 112, respectively. Connection holes may be provided at the ends of the link 120, pivot posts may be provided on the first diaphragm 111 and the second diaphragm 112, and the link 120 may be fitted onto the pivot posts through the connection holes, thereby realizing the pivotal connection between the link 120 and the first diaphragm 111 and the second diaphragm 112. Alternatively, connection holes may be provided on the first diaphragm 111 and the second diaphragm 112, pivot posts may be provided at the ends of the link 120, and the link 120 may extend into the connection holes through the pivot posts, thereby realizing the pivotal connection between the first diaphragm 111 and the second diaphragm 112.

[0042] For example, three links 120 are provided between the first diaphragm 111 and the second diaphragm 112. When the first diaphragm 111 reciprocates, the three links 120 are oscillated simultaneously, and the second diaphragm 112 can be reciprocated simultaneously via the three links 120. Because there is a gap between the end of the link 120 and the side wall of the notch, the delay time of the second diaphragm 112 relative to the first diaphragm 111 is short, and the first diaphragm 111 and the second diaphragm 112 can be considered to be moving synchronously. Of course, one, two, four, or more links 120 may also be provided between the first diaphragm 111 and the second diaphragm 112, and the present application is not limited thereto.

[0043] 7 to 10, in one embodiment of the present application, the reciprocating motion of a plurality of vibrating plates 110 is in the same direction. By making the reciprocating motion of two adjacent vibrating plates 110 in the same direction, the vibration area of ​​the wiping mechanism is increased, and the cleaning efficiency and cleaning effect of the wiping mechanism are improved.

[0044] Two adjacent diaphragms 110 are fixedly connected via a link 120, i.e., the first diaphragm 111 and the second diaphragm 112 can move in perfect synchronization without delay. Here, both ends of the link 120 can be connected to the first diaphragm 111 and the second diaphragm by adhesive, welding, engagement, riveting, etc., in order to facilitate the assembly and maintenance of the first diaphragm 111 and the second diaphragm. Of course, the link 120 and the first diaphragm 111 and the second diaphragm can be integrally formed, thereby improving the structural strength of the vibration assembly 200 and ensuring that the first diaphragm 111 and the second diaphragm 112 move in perfect synchronization.

[0045] For example, three links 120 are provided between the first diaphragm 111 and the second diaphragm 112, and when the first diaphragm 111 reciprocates, the second diaphragm 112 can be simultaneously reciprocated via the three links 120. Of course, one, two, four or more links 120 may also be provided between the first diaphragm 111 and the second diaphragm 112, and the present application is not limited thereto.

[0046] In one embodiment of the present application, one of two adjacent diaphragms 110 is provided with a connecting portion 1110, and the connecting portion 1110 and the link 120 are respectively installed on both sides in the width direction of the diaphragm 110. For example, as shown in Figures 4 and 5, the connecting portion 1110 and the link 120 are located on both sides in the width direction of the first diaphragm 111. By respectively installing the connecting portion 1110 and the link 120 on both sides in the width direction of the diaphragm 110, it is easy to connect the vibration link 210 to the diaphragm 110 in a transmission manner, and it is easy to structurally arrange the vibration assembly 200 relative to the diaphragm 110.

[0047] The connecting portion 1110 and the link 120 are respectively disposed on the same side in the width direction of the other diaphragm 110. For example, as shown in FIGS. 4 and 5, the connecting portion 1110 and the link 120 are disposed on the same side in the width direction of the second diaphragm 112. By disposing the connecting portion 1110 and the link 120 on both sides in the width direction of the first diaphragm 111, the connecting portion 1110 and the link 120 are disposed on the same side in the width direction of the second diaphragm 112. By disposing the vibrating assembly 200 in a space other than the first diaphragm 111 and the second diaphragm 112, the first diaphragm 111 and the second diaphragm 112 can be disposed closely together, and the layout of the multiple diaphragms 110 can be made more compact. As a result, the cleaning member is driven by the two diaphragms 110 to quickly and continuously wipe the area to be cleaned, and the dirt removal efficiency and dirt removal effect of the wiping mechanism are further improved.

[0048] 4, 5, 8 and 9, the wiping mechanism further includes a reset assembly 130. The reset assembly 130 includes a fixed arm 131 and an elastic arm 132. The fixed arm 131 is fixedly connected to the bottom plate 300, and the elastic arm 132 is connected to the fixed arm 131. The elastic arm 132 is located on the diaphragm 110. When the diaphragm 110 is in its initial position, the elastic arm 132 is in a free state. When the diaphragm 110 moves back and forth away from the initial position, the elastic arm 132 can come into contact with the elastic arm 132 to deform it. By installing the reset assembly 130, on the one hand, positional restrictions are formed for the first vibration plate 111 and the second vibration plate 112 in the direction of reciprocating motion, and on the other hand, the elastic arm 132 increases the movement speed of the first vibration plate 111 and the second vibration plate 112 at the stage when the elastic deformation of the elastic arm 132 recovers during reciprocating motion, thereby improving the wiping effect of the first vibration plate 111 and the second vibration plate 112.

[0049] 4 and 8, two reset assemblies 130 are provided on the first diaphragm 111 and the second diaphragm 112, and one reset assembly 130 acts simultaneously on the first diaphragm 111 and the second diaphragm 112. Mounting holes are provided in the elastic arms 132 of the reset assemblies 130, and protruding posts are provided on the first diaphragm 111 and the second diaphragm 112. After the reset assemblies 130 are attached to the first diaphragm 111 and the second diaphragm 112, the protruding posts are inserted into the mounting holes, and when the first diaphragm 111 and the second diaphragm 112 reciprocate, the elastic arms 132 are deformed by the protruding posts provided on the first diaphragm 111 and the second diaphragm 112. Here, one reset assembly 130 includes two parallel elastic arms 132, and the two elastic arms 132 are connected via three fixed arms 131. The three fixed arms 131 are located in the intermediate region between the first vibration plate 111 and the second vibration plate 112, respectively, and are located on both sides of the opposite side. The fixed arms 131 and the fixed plate 400 can be fixedly connected by a method such as screws.

[0050] The reset assembly 130 may be an integral frame structure, and may be made of a plastic or metal material with excellent elasticity.

[0051] 4 and 8, the two reset assemblies 130 and the three links 120 are alternately installed along the direction of reciprocating motion to improve the effect of the reset assemblies 130 on the first diaphragm 111 and the second diaphragm 112. Of course, the two reset assemblies 130 may also be installed adjacent to each other, and the present application is not limited thereto.

[0052] The bottom plate 300 is provided with first position restricting blocks at both ends of the first diaphragm 111, and the first position restricting blocks are installed on the bottom plate 300 to restrict the range of reciprocating motion of the first diaphragm 111. The bottom plate 300 is provided with second position restricting blocks at both ends of the second diaphragm 112, and the second position restricting blocks are used to restrict the range of reciprocating motion of the second diaphragm 112. Here, the first and second position restricting blocks may be elastic rubber blocks, providing a cushioning effect.

[0053] Specifically, as shown in Figures 6 and 10, an assembly notch 1112 is provided in the first vibration plate 111, and a water-discharging nozzle 200 is installed near the assembly notch 1112 of the first vibration plate 111. The water-discharging nozzle 200 is used to connect to a water-discharging device via a hose, and water flowing out from the water-discharging device flows through the water-discharging nozzle 200 to the first vibration plate 111 and the second vibration plate 112, wetting the wiping cloths of the first vibration plate 111 and the second vibration plate 112 or injecting cleaning liquid into the wiping cloths of the first vibration plate 111 and the second vibration plate 112, thereby improving the cleaning effect.

[0054] One or more water-spouting nozzles may be installed; that is, an assembly notch 1112 may be similarly provided on the second diaphragm 112, and a water-spouting nozzle may be installed near the assembly notch 1112 of the second diaphragm 112. Water may be spouted from the multiple water-spouting nozzles onto the first diaphragm 111 and the second diaphragm 112, respectively, to improve the uniformity of the water spouting, thereby enabling the wiping cloths on the first diaphragm 111 and the second diaphragm 112 to be uniformly wetted. Here, the water-spouting device may be connected to the cleaning liquid outlet of the water tank, and the cleaning liquid may flow to the water-spouting device through the cleaning liquid outlet of the water tank. The output / flow rate of the water-spouting device may be adjustable, thereby controlling the amount of water spouting according to actual needs.

[0055] Specifically, independent hook-sided Velcro strips are provided on the surfaces of the multiple diaphragms 110, i.e., one independent hook-sided Velcro strip is provided on each of the first diaphragm 111 and the second diaphragm 112. By providing one independent hook-sided Velcro strip on each of the first diaphragm 111 and the second diaphragm 112, it becomes easy to assemble wiping cloths on the first diaphragm 111 and the second diaphragm 112. The wiping cloths may be directly attached to the hook surfaces of the Velcro strips. Furthermore, gaps formed by the hook-sided Velcro strips make it easy to spray water onto the wiping cloths on the first diaphragm 111 and the second diaphragm 112 through the multiple water-spouting nozzles, thereby making it possible to uniformly wet both the wiping cloths on the first diaphragm 111 and the second diaphragm 112. Furthermore, by attaching the wiping cloths to the hook surface of the Velcro strips, it becomes easy to clean and replace the wiping cloths.

[0056] 2, the wiping mechanism further includes a fixed plate 400. The fixed plate 400 is fitted to the bottom plate 300 to form an accommodating space, the vibrating assembly 200 is disposed within the accommodating space, the fixed plate 400 is provided with a wiping window, the first vibrating plate 111 and the second vibrating plate 112 are exposed through the wiping window, and the first vibrating plate 111 and the second vibrating plate 112 are positioned on the same plane as the fixed plate 400, so that the first vibrating plate 111 and the second vibrating plate 112 and the surface of the fixed plate 400 together form a wiping surface, that is, a wiping cloth may be attached to the surface of the fixed plate 400 by providing hook-shaped Velcro.

[0057] The size of the wiping window must satisfy the requirement that it does not interfere with the reciprocating motion of the first vibration plate 111 and the second vibration plate 112, and the shape of the wiping window must match the shape of the structure formed by combining the first vibration plate 111 and the second vibration plate 112, so that the size of the gap between the spatial wiping window and the first vibration plate 111 and the second vibration plate 112 can prevent foreign matter on the surface to be wiped from passing through the gap and entering the inside of the wiping mechanism.

[0058] Specifically, the vibration assembly 200 includes a vibration device and a vibration link 210. The vibration device may be a motor, which outputs power through an output shaft of the motor, and a rear drive wheel is connected to the output shaft of the motor, and the drive wheel has an asymmetric structure, and the vibration link 210 is connected to the output shaft of the motor through the drive wheel, and the asymmetric rotation of the drive wheel realizes reciprocating motion, thereby realizing the reciprocating motion of the multiple vibration plates 110.

[0059] The vibration link 210 includes a first segment and a second segment, the first segment and the second segment being formed in an L-shape, the first segment of the vibration link 210 connecting the drive wheel and the second segment so that the vibration link 210 extends to a predetermined position, and the extension direction of the first segment is perpendicular to the extension direction of the second segment so that the reciprocating motion direction of the vibration link 210 is approximately perpendicular to the running direction of the machine.

[0060] A vibration damper 220 is fitted to the first segment of the vibration link 210. The vibration damper 220 damps vibration and reduces jitter during exercise driven by the drive wheel, allowing the vibration link 210 to vibrate smoothly within its range of motion. The vibration damper 220 is made of a soft material, and may have a rubber structure. Meanwhile, the vibration damper 220 can also protect the vibration link 210 from damage due to interference with other components.

[0061] The rotation speed of the motor can be adjusted according to the operating environment of the wiping mechanism, and different cleaning effects can be achieved by adjusting the preset reciprocating period of the reciprocating motion of the vibrating plate 110, i.e., adjusting the vibration frequency of the vibrating plate 110. For example, when operating on flat ground, the preset reciprocating period is automatically and dynamically adjusted to be longer, and the water volume of the water pump is automatically and dynamically adjusted to be smaller; when the automatic cleaning device operates on less flat ground, the preset reciprocating period is automatically and dynamically adjusted to be shorter, and the water volume of the water pump is automatically and dynamically adjusted to be larger, thereby achieving better cleaning effects.

[0062] An embodiment of the present application further provides a cleaning device, and as shown in Fig. 11, the cleaning device 20 includes the above-mentioned wiping mechanism 10. The cleaning device 20 may be, for example, a mop / scrub robot, a vacuum suction robot, a window climbing robot, etc.

[0063] In the cleaning device provided by the present application, the wiping assembly in the wiping mechanism includes a plurality of vibrating plates, and the vibrating assembly can drive a vibrating link to reciprocate along a predetermined direction, and the vibrating link can then reciprocate the vibrating plate at which the connecting portion is located when reciprocating along the predetermined direction, and a link is provided between two adjacent vibrating plates, so that when one vibrating plate reciprocates, the other vibrating plate can be synchronously reciprocated through the link, and when the frequency of the reciprocating motion is relatively high, the reciprocating motion of the vibrating plate can be regarded as high-frequency vibration, which increases the vibration area of ​​the wiping mechanism and improves the cleaning efficiency and cleaning effect of the cleaning device. For more beneficial effects of the cleaning device, please refer to the description in the above embodiment of the cleaning device, and further description thereof will be omitted here.

[0064] Specifically, the cleaning device 20 may further include a mobile platform, a sensing system, a control system, a drive system, a cleaning module, an energy system, and a human-machine interaction system.

[0066] The sensing system includes a positioning device located above the mobile platform, a buffer located at the front of the mobile platform, and sensing devices such as cliff sensors, ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers located at the bottom of the mobile platform to provide various position and motion status information of the machine to the control system. Cliff sensors are installed at the bottom of the mobile platform and in front and rear of the drive wheel assembly. The cliff sensors are used to prevent the automatic cleaning equipment from falling when reversing, thereby avoiding damage to the automatic cleaning equipment. The positioning devices include, but are not limited to, cameras and laser ranging devices. Each assembly in the sensing system may operate independently or in cooperation to more accurately achieve the intended function. The cliff sensors and ultrasonic sensors identify the surface to be cleaned and determine its physical characteristics, including the surface material and cleaning level. These sensors can be combined with cameras, laser ranging devices, and other sensors to achieve more accurate determinations. Here, a buffer is provided at the front part of the moving platform, which detects objects in the travel path of the automatic cleaning equipment via a sensor system, for example an infrared sensor, so that the automatic cleaning equipment can pass through the objects detected by the buffer.

[0067] The control system is installed on a circuit board within the mobile platform and includes a computing processor, such as a central processing unit or an application processor, in communication with a non-transitory memory, such as a hard disk, flash memory, or random access memory, wherein the application processor is configured to receive environmental information sensed by the plurality of sensors transmitted from the sensing system, use a position estimation algorithm to draw a real-time map of the environment in which the automatic cleaning equipment is located based on obstacle information fed back from the laser ranging device, and autonomously determine a driving path based on the environmental information and the environmental map, and then control the drive system to perform operations such as moving forward, backward, and steering based on the autonomously determined driving path.

[0068] The drive system includes a drive motor, a drive wheel assembly, and a steering assembly. The drive motor provides power for turning the drive wheel assembly and the steering assembly.

[0069] The energy system includes a rechargeable battery, and a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit may be connected to the rechargeable battery, and the charging control circuit, the battery pack charging temperature detection circuit, and the battery undervoltage monitoring circuit are further connected to a single-chip microcomputer control circuit.

[0070] The human-machine interaction system may include buttons on a main body panel for allowing a user to select functions, a display screen and / or an indicator light and / or a speaker for displaying the current machine status or function selection items to the user, and a mobile phone client program. For a path-navigation type cleaning device, the mobile phone client can display a map of the environment in which the machine is located and the location of the device to the user, thereby providing the user with richer and more user-friendly functions.
