DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present application.

[0051] It should be noted that, in order to facilitate the description of the cleaning piece fixing assembly 100, the fixing component 1 is placed in the up-down direction, and since the fixing component 1 and the connecting component 2 are both arranged below the fixing component 1, in order to clearly show the structure of the present application, the cleaning piece fixing assembly 100 is inverted in Figure 1 , in other words, the up-down direction of the cleaning piece fixing assembly 100 in the actual use scene is the up-down direction marked in Figure 1 . The cleaning piece fixing assembly 100 can be used for a sweeping robot or a window-cleaning robot.

[0052] The first aspect embodiment of the present application provides a cleaning piece fixing assembly 100, which comprises a fixing component 1 and a connecting component 2. The fixing component 1 has a first end face and a second end face in the thickness direction thereof. The first end face is used for fixing a cleaning piece, and the second end face is arranged adjacent to a robot main body. The connecting component 2 penetrates through the first end face and the second end face, and the side of the connecting component 2 away from the second end face extends into the robot main body. The connecting component 2 has an open position and a locking position. In the open position, the fixing component 1 can be separated from the robot main body, and in the locking position, the fixing component 1 is connected with the robot main body.

[0053] As shown in Figure 1 , the first end face of the fixing component 1 is a lower end face, and the second end face of the fixing component 1 is an upper end face, that is, the lower end face of the fixing component 1 is used for fixing a cleaning piece. For example, the cleaning piece can be a cleaning cloth, or the cleaning piece is a brush.

[0054] For example, as shown in Figure 1 , the lower end face of the fixing component 1 can be provided with a magic tape. The cleaning piece is fixed to the lower end face of the fixing component 1 through the magic tape, or the cleaning piece is installed on the lower end face of the fixing component 1 through magnetic attraction or clamping and the like.

[0055] The connecting component 2 penetrates the fixing component 1 in the up-down direction, and the upper end of the connecting component 2 can extend into the robot body, and the lower end of the connecting component 2 is flush with the lower end surface of the fixing component 1, or the lower end of the connecting component 2 is recessed relative to the lower end surface of the fixing component 1, in other words, the lower end of the connecting component 2 does not protrude beyond the lower end surface of the fixing component 1, so that the protrusion of the connecting component 2 can avoid affecting the stability of the connection between the cleaning piece and the fixing component 1, and if the connecting component 2 protrudes outward, the protruding connecting component 2 will lift the cleaning piece, which not only reduces the contact area between the cleaning piece and the fixing component 1, but also has the risk of scratching the cleaning surface.

[0056] The connecting component 2 has an open position and a locking position, and the connecting component 2 is rotatable relative to the fixing component 1 to switch between the open position and the locking position. In the open position, the fixing component 1 can be separated from the robot body, and in the locking position, the fixing component 1 is connected to the robot body.

[0057] In this way, the connecting component 2 is used to quickly connect the fixing component 1 and the robot body, improve the assembly efficiency of the cleaning piece, and the rotatable connecting component 2 conveniently realizes locking and opening, and the disassembly and assembly of the fixing component 1 can be realized without professional tools, which simplifies the connection process and improves the user experience.

[0058] As shown in Figure 2 and Figure 3 The fixing component 1 is provided with a connecting groove 11 and a connecting hole 12, the connecting hole 12 is located on the inner bottom surface of the connecting groove 11, and the connecting hole 12 penetrates the fixing component 1.

[0059] The connecting groove 11 is a circular groove, the connecting hole 12 is located at the bottom of the connecting groove 11, and the connecting hole 12 penetrates the fixing component 1, the diameter of the connecting hole 12 is smaller than the diameter of the connecting groove 11, and the lower end surface of the fixing component 1 is further provided with unlocking and locking marks, which are located on the periphery of the connecting groove 11. By setting the unlocking and locking marks, the operator can easily identify whether the connecting component 2 is currently in the locking state or the open state.

[0060] In some embodiments, the connecting component 2 includes a connecting knob 21 and a locking rod 22, the locking rod 22 is connected to the side of the connecting knob 21 away from the second end surface, in the locking position, the locking rod 22 is adapted to abut the inner bottom surface of the connecting seat 4 in the robot body to connect the fixing component 1 and the robot body, in the open position, the connecting knob 21 and the locking rod 22 are separated from the inner bottom surface of the connecting seat 4 to separate the fixing component 1 from the robot body, and in the locking position, the connecting knob 21 and the locking rod 22 extend into the robot body to connect the fixing component 1 and the robot body. See Figure 4As shown, the connecting knob 21 comprises a body and a cap, both of which are cylindrical, the cap has a larger diameter than the body, and the height of the cap is smaller than that of the body. When the connecting knob 21 is placed in the up-down direction, the locking rod 22 is located at the upper end of the body, and the rotation of the connecting knob 21 drives the rotation of the locking rod 22.

[0061] It should be noted that when the positions of the connecting knob 21 and the locking rod 22 are opposite to the position of the connecting hole 12, in other words, when the positions of the connecting knob 21 and the locking rod 22 in the up-down direction are opposite to the position of the connecting hole 12, the connecting knob 21 and the locking rod 22 can freely pass through the connecting hole 12 so that the locking rod 22 can extend into or out of the robot body.

[0062] When the positions of the locking rod 22 and the connecting hole 12 are staggered, the locking rod 22 can be in contact with the upper end surface of the fixed component 1, and the connecting component 2 cannot be separated from the fixed component 1, in other words, when the positions of the locking rod 22 and the connecting hole 12 are staggered, and at this time the locking rod 22 is located in the connecting hole 12.

[0063] Optionally, an arrow direction mark is arranged on the cap, when the connecting knob 21 rotates, the arrow direction mark can point to the unlocking and locking marks, so as to facilitate the operator to identify the on-off state of the connecting component 2 and improve the user experience.

[0064] In this way, the connecting knob 21 can be placed in the connecting groove 11, avoiding the exposure of the connecting knob 21, reducing or avoiding the risk of wear of the connecting knob 21 on the to-be-cleaned plane, and the connecting hole 12 can avoid the falling of the connecting knob 21 from the fixed component 1, thereby improving the connection stability of the fixed component 1 and the robot body.

[0065] As shown in Figure 4 As shown, the extension direction of the locking rod 22 is arranged orthogonally to the extension direction of the connecting knob 21. In this way, when the locking rod 22 extends into the robot body, the contact area between the locking rod 22 and the robot body can be increased, thereby ensuring the connection stability of the fixed component 1 and the robot body.

[0066] In some embodiments, a recessed part 111 is arranged on the inner bottom surface of the connecting groove 11, the recessed part 111 is recessed towards the direction away from the first end surface, and a first limiting protrusion 23 is arranged on the side end surface of the connecting knob 21 close to the connecting groove 11, when the connecting component 2 is converted between the open position and the locking position, the first limiting protrusion 23 is movable in the recessed part 111.

[0067] As shown in Figure 3 and Figure 4As shown, the inner bottom surface of the connecting groove 11 is concave upward to form a recessed portion 111, and a stepped portion 112 is formed between the recessed portion 111 and the inner bottom surface of the connecting groove 11. The upper end surface of the connecting knob 21 is provided with a first limiting protrusion 23, and the first limiting protrusion 23 is located in the recessed portion 111. When the connecting knob 21 rotates, the first limiting protrusion 23 is always located in the recessed portion 111, thereby limiting the rotation range of the connecting knob 21, avoiding the rotation angle of the connecting knob 21 being too large, and preventing the connecting knob 21 from repeatedly changing between the locked and unlocked positions, thereby improving the assembly precision and user experience.

[0068] Optionally, a third limiting protrusion 24 can also be arranged on the connecting knob 21. When the connecting knob 21 extends into the connecting hole 12, the lower end surface of the third limiting protrusion 24 abuts against the upper end surface of the fixed component 1. In other words, the third limiting protrusion 24 is used to limit the connecting knob 21 in the up-down direction, thereby preventing the connecting knob 21 from falling out of the connecting hole 12 when the connecting knob 21 is in the unlocked position.

[0069] In this way, the recessed portion 111 can provide installation space for the first limiting protrusion 23, improve the space utilization, and facilitate the lightweight design of the cleaning device.

[0070] In some embodiments, the fixed component 1 is provided with a second limiting protrusion 13, the second limiting protrusion 13 is located in the recessed portion 111, and the second limiting protrusion 13 is arranged on the moving path of the first limiting protrusion 23.

[0071] As shown in Figure 3 and Figure 4 The second limiting protrusion 13 is located in the recessed portion 111, and the position of the second limiting protrusion 13 is opposite to the position of the locking mark. In other words, the rotation area of the first limiting protrusion 23 in the recessed portion 111 is located between the stepped portion 112 and the second limiting protrusion 13. In other words, when the first limiting protrusion 23 rotates to the position of the second limiting protrusion 13, the connecting knob 21 is in the locked position. Conversely, when the first limiting protrusion 23 rotates to the stepped portion 112, the connecting knob 21 is in the unlocked position.

[0072] In this way, the rotation of the connecting knob 21 is limited by the first limiting protrusion 23 and the second limiting protrusion 13, thereby preventing the connecting knob 21 from rotating and moving when the fixed component 1 changes position on the robot body, and preventing the connecting knob 21 from rotating to the unlocked position and causing the locking to fail.

[0073] In some embodiments, the cleaning component fixing assembly 100 further comprises a floating component 3, the floating component 3 is located on the second end surface, one end of the floating component 3 is connected to the fixed component 1, and the other end of the floating component 3 can extend into the robot body to make the fixed component 1 approach or move away from the robot body.

[0074] See Figure 5 and Figure 6 As shown in FIG. 1 and FIG. 2, the lower end of the floating component 3 is connected with the upper end surface of the fixed component 1, and the upper end of the floating component 3 can extend into the robot body.

[0075] When the fixed component 1 is connected with the robot body, the floating component 3 can provide the fixed component 1 with a moving allowance in the up-down direction, in other words, when the fixed component 1 is subjected to a pressure in the up-down direction, the fixed component 1 can move close to or away from the robot body due to the presence of the floating component 3. In this way, the floating of the fixed component 1 can be realized by using the floating component 3, and when the fixed component 1 is subjected to an external force, the overall floating of the fixed component 1 can be realized, and the cleaning member can adaptively float along the surface to be cleaned during cleaning, so that the cleaning pressure distribution is more uniform, and the cleaning effect is improved.

[0076] In some embodiments, the floating component 3 comprises a support 31, a guide column 32 and an elastic member 33. One end of the guide column 32 extends into the support 31, and the guide column 32 is movable along the height direction of the support 31. The other end of the guide column 32 can extend into the robot body. The elastic member 33 is located between the guide column 32 and the support 31.

[0077] As shown in FIG. 1 and FIG. 2, the lower end of the floating component 3 is connected with the upper end surface of the fixed component 1, and the upper end of the floating component 3 can extend into the robot body. Figure 5 Figure 6 As shown in FIG. 1 and FIG. 2, the lower end of the floating component 3 is connected with the upper end surface of the fixed component 1, and the upper end of the floating component 3 can extend into the robot body.

[0078] The elastic member 33 is located between the inner bottom surface of the guide column 32 and the support 31. For example, the elastic member 33 can be a spring, and the elastic member 33 can also be an elastic sheet. The upper end of the elastic member 33 abuts against the guide column 32, and the lower end of the elastic member 33 abuts against the inner bottom surface of the support 31.

[0079] In this way, the guide column 32 can be used to improve the precision of the movement of the fixed component 1, and the elastic member 33 can not only provide a certain floating buffer, but also ensure the resetting of the fixed component 1.

[0080] In some embodiments, the side wall of the support 31 is provided with a guide groove 311 extending along the height direction of the support 31. The guide column 32 is provided with a guide block 321, and the guide block 321 is clamped in the guide groove 311 and is movable in the guide groove 311.

[0081] As shown in FIG. 1 and FIG. 2, the lower end of the floating component 3 is connected with the upper end surface of the fixed component 1, and the upper end of the floating component 3 can extend into the robot body. Figure 5 Figure 6 ​​As shown, the guide groove 311 extends in the vertical direction, and there are two guide grooves 311. The two guide grooves 311 are arranged at intervals in the circumferential direction of the support 31. The outer wall surface of the guide column 32 is provided with a guide block 321. The guide block 321 is locked in the slot and can move in the guide groove 311. The guide groove 311 can improve the movement accuracy of the guide column 32 in the support 31 and reduce the risk of misalignment of the fixed part 1.

[0082] When an external force pushes the fixed component 1 upward, it causes the guide post 32 to move upward along the guide groove 311 and compresses the internal spring. When the external force is removed, the compressed spring releases its elasticity, pushing the guide post 32 and the fixed component 1 downward to reset, so that they always fit against the surface to be cleaned, thus realizing the up-and-down floating of the fixed component 1.

[0083] In some embodiments, the guide post 32 has a receiving cavity, and the elastic member 33 is located in the receiving cavity. One end of the elastic member 33 abuts against the inner bottom surface of the receiving cavity, and the other end of the elastic member 33 abuts against the inner bottom surface of the support 31.

[0084] See Figure 6 As shown, the guide post 32 has a receiving cavity extending in the vertical direction. The elastic member 33 extends into the receiving cavity. The upper end of the elastic member 33 abuts against the bottom surface of the receiving cavity, and the lower end of the elastic member 33 abuts against the inner bottom surface of the support 31. The receiving cavity can improve the accuracy of the contraction and extension of the elastic member 33 and prevent the elastic member 33 from being misaligned.

[0085] See Figure 6 As shown, the support 31 is also provided with a connecting protrusion 312 inside. The connecting protrusion 312 extends along the height direction of the support 31, and the connecting protrusion 312 extends at least partially into the elastic member 33.

[0086] For example, the connecting protrusion 312 is integrally formed with the support 31, or the connecting protrusion 312 is integrally formed with the fixing component 1, thereby improving the structural strength of the connecting protrusion 312. The connecting protrusion 312 can be used to radially limit the elastic element 33 and prevent the spring from being misaligned.

[0087] In some embodiments, a first adsorption member 34 is provided on the side of the guide post 32 away from the first end face, and the first adsorption member 34 is used to adsorb and connect with the second adsorption member 6 in the robot body.

[0088] See Figure 5 and Figure 6 As shown, the upper end of the guide post 32 is provided with a first adsorption member 34. When the fixing component 1 is connected to the robot body, the upper end of the guide post 32 extends into the robot body, and the first adsorption member 34 is adsorbed and connected with the second adsorption member 6 inside the robot body. By using the first adsorption member 34 and the second adsorption member 6 for adsorption connection, rapid connection and positioning can be achieved.

[0089] Optionally, when the first adsorption component 34 and the second adsorption component 6 adsorb, a sound will be emitted. The sound indicates that the fixed component 1 and the robot body have been positioned. At this time, the connection knob 21 can be rotated to lock, thereby improving the accuracy of the connection between the fixed component 1 and the robot body and the user experience.

[0090] In some embodiments, on a projection plane parallel to the length and width directions of the fixed component 1, the connecting component 2 and the floating component 3 are arranged diagonally at intervals.

[0091] See Figure 1 As shown, on the projection plane parallel to the length and width directions of the fixed component 1, taking the outer contour of the projection of the fixed component 1 as a rectangle as an example, the connecting component 2 and the floating component 3 are respectively set at the four corners of the rectangle, and the connecting component 2 and the floating component 3 are located on the diagonal of the rectangle. This setting ensures the stability of the connection and also ensures the floating nature of the fixed component 1.

[0092] It should be noted that if the outer contour of the projection of the fixed component 1 is a circle, the connecting component 2 and the floating component 3 are arranged in the circumferential direction of the circle, and the circumferential angle between the connecting component 2 and the floating component 3 can be 180°.

[0093] In some embodiments, if there are two connecting parts 2 and two floating parts 3, the two connecting parts 2 are arranged diagonally on the projection plane parallel to the length and width directions of the fixed part 1, and the two floating parts 3 are arranged diagonally on the projection plane parallel to the length and width directions of the fixed part 1.

[0094] It should be noted that when there are two connecting parts 2 and two floating parts 3, the two connecting parts 2 are arranged diagonally, the two floating parts 3 are arranged diagonally, or one of the two connecting parts 2 is arranged diagonally with one of the two floating parts 3, and the remaining connecting part 2 is arranged diagonally with the other remaining floating part 3.

[0095] If there is one connecting component 2 and three floating components 3, the connecting component 2 and one of the three floating components 3 are arranged diagonally on the projection plane parallel to the length and width directions of the fixed component 1.

[0096] It should be noted that when there is only one connecting part 2 and three floating parts 3, one of the three floating parts 3 is arranged diagonally, and the remaining two floating parts 3 are arranged diagonally.

[0097] If there are three connecting parts 2 and one floating part 3, one of the three connecting parts 2 and the floating part 3 are arranged diagonally, and the remaining two connecting parts 2 are arranged diagonally.

[0098] If there are four connecting parts 2 and no floating parts 3, the four connecting parts 2 are respectively located at the four inner corners of the fixed part 1, and the connecting knob 21 in the connecting parts 2 plays the role of guiding the up and down floating.

[0099] A second aspect of the present invention provides a cleaning device, including a cleaning component fixing assembly 100 and a robot body. The cleaning component fixing assembly 100 is any one of the cleaning component fixing assemblies in the first aspect. The robot body includes a base 200, and the cleaning component fixing assembly 100 is connected to the base 200.

[0100] See Figure 7 As shown, the cleaning component fixing assembly 100 is located below the base 200, the upper ends of the connecting component 2 and the floating component 3 both extend into the base 200, and the cleaning component is located below the fixing component 1.

[0101] See Figure 8 As shown, the base 200 is provided with a connecting seat 4 and a mounting hole 5. The locking rod 22 in the connecting part 2 of the cleaning part fixing assembly 100 can extend into the connecting seat 4, and the floating part 3 in the cleaning part fixing assembly 100 can extend into the mounting hole 5.

[0102] For example, the connecting seat 4 and the base 200 are integrally formed. For instance, when the base 200 is a plastic part, the connecting seat 4 and the base 200 are integrally injection molded. The opening position of the mounting hole 5 corresponds to the position of the floating part 3, and the opening position of the connecting seat 4 corresponds to the position of the connecting part 2.

[0103] For example, the connecting seat 4 has a cavity 41 and a limiting hole 42. The limiting hole 42 connects the cavity 40 and the outside. When the connecting part 2 in the cleaning part fixing assembly is in the open position, the locking rod 22 in the connecting part 2 can freely pass through the limiting hole 42. When the connecting part 2 in the cleaning part fixing assembly is in the locked position, the locking rod 22 in the connecting part 2 is staggered with the limiting hole 42 and the locking rod 22 abuts against the inner bottom surface of the cavity 41 inside the connecting seat 4.

[0104] See Figure 5 and Figure 8As shown, the connecting seat 4 is provided with a limiting hole 42 on the side facing the fixing component 1. The inner contour of the limiting hole 42 is the same as the outer contour formed by the locking rod 22 and the upper end of the connecting knob 21. For example, the inner contour of the limiting hole 42 is a closed annular shape formed by a rectangle and a circle, while the outer contour of the shape formed by the locking rod 22 and the upper end of the connecting knob 21 is the same as a closed annular shape formed by a rectangle and a circle. In this way, when the locking rod 22 is facing the limiting hole 42, the locking rod 22 and part of the connecting knob 21 can freely pass through the limiting hole 42.

[0105] Conversely, when the locking rod 22 and the connecting knob 21 are rotated and misaligned with the limiting hole 42, the lower end face of the locking rod 22 abuts against the inner bottom surface of the cavity 41, thereby achieving the connection between the fixing component 1 and the base 200.

[0106] When the cleaning component fixing assembly 100 is connected to the base 200, the locking rod 22 and part of the connecting knob 21 extend into the mounting hole 5.

[0107] This configuration provides mounting space for the connecting knob 21 and locking lever 22 using the connecting base 4, and also provides displacement space for the connecting component 2.

[0108] In some embodiments, a second adsorption member 6 is provided in the mounting hole 5, and the second adsorption member 6 can be adsorbed and connected to the first adsorption member 34 in the floating member 3.

[0109] See Figure 8 As shown, the position of the second adsorption member 6 corresponds to the position of the first adsorption member 34. For example, the first adsorption member 34 can be a magnetic metal, such as an iron sheet or iron block, and the second adsorption member 6 can be a magnet. By using the first adsorption member 34 and the second adsorption member 6 for adsorption connection, quick connection and positioning can be achieved. Furthermore, the fact that the two are adsorbed together can prevent the locking rod 22 from suddenly falling off due to the lack of connection force between the fixing part 1 and the base 200 after unlocking. It also serves to protect the operator and the fixing part 1.

[0110] A third aspect of the present invention provides a cleaning system comprising: Cleaning equipment, such as the cleaning equipment in any of the second aspects; Cleaning equipment can be placed inside the base station.

[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
