On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] It should be understood that the terms used herein are only for the purpose of describing specific example embodiments and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "include", "comprise", "contain", and "have" are inclusive, and therefore specify the existence of stated features, steps, operations, elements and / or parts, but do not exclude the existence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not interpreted as necessarily requiring them to be performed in the specific order described or illustrated, unless the execution order is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0042] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0043] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is turned over, then the elements described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0044] A self-moving cleaning device is an intelligent household cleaning device that automatically sweeps away dust, debris and crumbs on the floor. The self-moving cleaning device works by sensing the surroundings through a built-in sensor system and using a motorized brush and vacuum cleaner to clean the floor. It can clean the entire room according to a preset route or random movement, and can also avoid obstacles and edges.

[0045] Modern self-moving cleaning equipment is usually equipped with multiple functions. For example, a mop cleaning component is added to realize a mopping function. The mop of the mop cleaning component can be a rotating type that can rotate, a vibrating type that can vibrate, or a traditional fixed type. However, when the above mop cleaning components are used to clean the floor near the wall or cabinet, the mopping effect cannot meet the user's satisfaction. The reason is that when the body of the self-moving cleaning equipment moves to contact the wall or cabinet, the mop and other cleaning parts cannot move toward the wall or cabinet, resulting in the mop cleaning component being able to perform mopping operations only within a certain range, and being unable to cover all areas near the wall or cabinet.

[0046] In view of this, the present embodiment provides a self-moving cleaning device, which aims to improve its structure so that cleaning parts such as a mop can be extended or retracted into the body to perform all-round cleaning of the wall or cabinet edge.

[0047] The following is combined with Figure 1-10 The structure of the self-moving cleaning device provided in this embodiment is described.

[0048] Figure 1 The structure diagram of the self-moving cleaning device according to the embodiment of the utility model is schematically shown. Figure 2 The structure diagram of the self-moving cleaning device according to the embodiment of the utility model when the cleaning member is retracted is schematically shown. Figure 3The structure diagram of the self-moving cleaning device according to the embodiment of the utility model is schematically shown when the cleaning member is extended. It should be noted that: Figure 1 A schematic diagram showing the bottom structure of the self-moving cleaning device is shown, Figure 2 and Figure 3 Only a partial structural schematic diagram of the lower shell of the self-moving cleaning device body is shown.

[0049] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 As shown in , the self-moving cleaning device 100 provided in this embodiment includes a body 10, a telescopic driving assembly 20 and a cleaning assembly 30, the telescopic driving assembly 20 is installed on the body 10, the cleaning assembly 30 includes a cleaning member 31, the cleaning assembly 30 is connected to the telescopic driving assembly 20, and the telescopic driving assembly 20 is used to drive the cleaning assembly 30 to move, so as to drive at least a part of the cleaning member 31 of the cleaning assembly 30 to extend or retract from one side of the body 10. Specifically, the telescopic driving assembly 20 has an extended state and a retracted state that can be switched to each other. Figure 3 In the extended state, at least part of the body of the cleaning member protrudes outward from the circumferential side wall of the body. Figure 2 In the retracted state, the cleaning member is placed on the inner side of the circumferential side wall of the machine body.

[0050] Among them, the body 10 of this embodiment serves as the installation base of various functional components, which includes an upper shell (not shown in the figure) and a lower shell 11 connected to each other, running wheels 12 for driving the body 10 to move, and a dust suction component 13 for absorbing dust.

[0051] The telescopic drive component 20 of the present embodiment is installed on the body 10, for example, between the upper shell and the lower shell 11. The "telescopic" in the telescopic drive component 20 can be understood as driving the cleaning member 31 of the cleaning component 30 to extend or retract, and cannot be simply understood as the driving form of the telescopic drive component 20 being a telescopic form. As long as the driving structure has the function of driving the cleaning member 31 to extend and retract, it can be used as the telescopic drive component 20 of the present embodiment. The feasible implementation methods of the telescopic drive component 20 are given below.

[0052] The cleaning assembly 30 of this embodiment can be an existing mopping assembly or an electric brush assembly. When the cleaning assembly 30 of this embodiment is a mopping assembly, the cleaning member 31 can be a mop, and the structure of the mopping assembly driving the mop to mop can be a rotating form, a vibrating form or a fixed form. In addition, when the cleaning assembly 30 of this embodiment is a mopping assembly, the self-moving cleaning device 100 can be equipped with an electric brush assembly on the side away from the mopping assembly.

[0053] The cleaning member 31 of this embodiment is at least partially extended or retracted from one side of the machine body 10 under the drive of the telescopic drive assembly, where "at least partially" can be understood as a part, a large part or the whole of one side of the cleaning member 31, and "extended or retracted from one side of the machine body 10" should be understood in a broad sense, for example, it can be understood that the cleaning member 31 is extended or retracted within one side of the orthographic projection range of the bottom of the machine body 10 on the ground, so the position of the cleaning member 31 should be located within the orthographic projection range or within the contour range of the machine body 10, and it cannot be understood that the cleaning assembly 30 must be located inside the machine body 10. For example, a receiving groove 111 can be provided on the outer wall surface of the bottom wall of the lower shell 11 of the machine body 10 of this embodiment, the receiving groove 111 is open at the bottom, and at least one side in the horizontal direction is provided with an inlet and outlet opening, and the cleaning member 31 is located in the receiving groove 111 and extends or retracts at the inlet and outlet opening. The cleaning member 31 in the receiving groove 111 is not completely located in the body 10 , but is only located in the receiving groove 111 at the bottom of the body 10 , and may be partially located in the receiving groove 111 in the vertical direction, but may not be completely accommodated in the receiving groove 111 .

[0054] In some examples, optionally, the number of cleaning components 30 of the present embodiment can be two, for example, two cleaning components 30 for mopping the floor can form a complete working surface, but only one cleaning component 30 can be connected to the telescopic drive component 20 of the present embodiment, because when cleaning the corner of a wall on one side, only one cleaning member 31 needs to be extended. When the self-moving cleaning device 100 provided by the embodiment of the utility model is used to wipe the ground near the bottom of the wall, the telescopic drive component 20 can drive a cleaning member 31 close to the wall in a cleaning component 30 to extend from one side of the body 10, so that the cleaning component 30 can cover the ground near the bottom of the wall, and can clean the right angle between the wall and the ground, which can improve the cleaning effect and cleaning efficiency near the bottom of the wall compared to the existing self-moving cleaning device 100. When it is not necessary to clean the vicinity of the wall, the extended cleaning component 30 is retracted so that the two cleaning components 30 can form a completed working surface during walking.

[0055] The telescopic drive assembly 20 of this embodiment can have various structural forms. In some examples, optionally, the telescopic drive assembly 20 of this embodiment includes a first drive component 21 and a transmission mechanism 22. The first drive component 21 is installed on the body 10, and the transmission mechanism 22 is connected to the first drive component 21 and the cleaning component 30 respectively, and is used to drive the cleaning member 31 to extend or retract, that is, the transmission mechanism 22 has the above-mentioned extended state and retracted state.

[0056] The first driving component 21 of the present embodiment can generate driving force by being powered on, and transmit the driving force to the transmission mechanism 22 of the present embodiment, and then the transmission mechanism 22 performs the conversion between transmission and driving force, and finally drives the cleaning member 31 of the present embodiment to extend or retract. Of course, the telescopic driving assembly 20 of the present embodiment can also be directly a telescopic rod assembly or a swing rod assembly, etc. The telescopic rod assembly can be pneumatic, electric or hydraulic, and drives the cleaning assembly 30 to move linearly by its own telescopic movement to achieve the extension or retraction of the cleaning member 31. The swing rod assembly can drive the cleaning assembly 30 to swing by its own swing to achieve the extension or retraction of the cleaning member 31.

[0057] Figure 4 The structure diagram of the telescopic drive assembly of the self-moving cleaning device according to the embodiment of the utility model is schematically shown. Figure 5 The schematic diagram (I) schematically shows a partial structure diagram of a cleaning component of a self-moving cleaning device according to an embodiment of the utility model, Figure 6 Schematically showing a partial structural diagram of a cleaning assembly 30 of a self-moving cleaning device according to an embodiment of the utility model (II);

[0058] Combined with Figure 4 , Attachment Figure 5 and attached Figure 6 As shown in, in some examples, optionally, the first driving component 21 of the present embodiment includes a first motor 211, and the transmission mechanism 22 of the present embodiment includes a first transmission gear 221 and a first transmission rack 222, the first transmission gear 221 is respectively connected to the first motor 211 and the first transmission rack 222, the first transmission rack 222 is connected to the cleaning assembly 30, and is used to drive the cleaning assembly 30 to move linearly along a first direction, and the first direction is parallel to the length direction of the first transmission rack 222.

[0059] The rotating shaft of the first motor 211 is coaxially connected to the first transmission gear 221 and can rotate synchronously. The first transmission gear 221 and the first transmission rack 222 are meshed with each other. The first transmission rack 222 is fixedly connected to the cleaning component 30. When the rotating shaft of the first motor 211 rotates, it drives the first transmission gear 221 to rotate, and then drives the first transmission rack 222 and the cleaning component 30 to move in a straight line to realize the extension or retraction of the cleaning member 31.

[0060] Of course, the structural form of the first transmission mechanism 22 of this embodiment is not limited to this. Other mechanisms that can convert the rotational motion of the shaft of the first motor 211 into linear motion can also be used as the transmission mechanism 22 of this embodiment, such as a crank-connecting rod mechanism, a screw mechanism, a bevel gear mechanism, etc., which are not listed one by one in this embodiment.

[0061] Combined with the attachment again Figure 5 and attached Figure 6 As shown in , in some examples, optionally, the transmission mechanism 22 of this embodiment further includes a transmission frame 223 , the transmission frame 223 is connected to the cleaning assembly 30 , and the first transmission rack 222 is connected to the cleaning assembly 30 through the transmission frame 223 .

[0062] The transmission frame 223 serves as a connecting structure connecting the first transmission rack 222 and the cleaning component 30, and also serves as an installation structure of the cleaning component 30. The transmission frame 223 is provided with a mounting hole or a mounting groove (not shown in the figure) and other structures. The cleaning component 30 is inserted into the mounting hole or the mounting groove. The first transmission rack 222 and the transmission frame 223 are connected in a fixed manner. The fixed connection method can be welding or threaded connection, or the two can be formed as one piece during processing.

[0063] In some examples, the transmission frame 223 is optionally slidably connected to the machine body 10. The transmission frame 223 is designed to be slidably connected to the machine body 10, so that the transmission frame 223 moves driven by the first transmission gear 221 and slides in the machine body 10, which can improve the stability of the transmission frame 223 during movement, thereby improving the stability of the telescopic movement of the cleaning member 31.

[0064] Figure 7 A partial structural diagram of the housing of a self-moving cleaning device according to an embodiment of the utility model is schematically shown.

[0065] Combined with Figure 7 As shown in, in some examples, optionally, the transmission frame 223 is provided with a sliding hole 2231 and a sliding member 2232, the sliding member 2232 has a first end and a second end opposite to each other (not marked in the figure), the first end is connected to the body 10, and the second end is passed through the sliding hole 2231 and is provided with a limiting portion 22321, and the limiting portion 22321 is used to limit the movement of the transmission frame 223 away from the first end.

[0066] A sliding hole 2231 and a sliding member 2232 are provided on the transmission frame 223. The sliding member 2232 can be a structure such as a screw. The first end of the sliding member 2232 is the tip of the screw, and the second end of the sliding member 2232 is an end of the screw with a nut. During assembly, the first end is first passed through the sliding hole 2231 and threadedly connected to the body 10, and then the second end is located in the sliding hole 2231, and the nut is gap-fitted or counteracted with the transmission frame 223 around the sliding hole 2231. The nut can limit the movement of the transmission frame 223 away from the first end.

[0067] In addition, in order to further improve the stability of the transmission frame 223 during the movement so that the transmission frame 223 can move along the first direction, the present embodiment further improves the structure of the transmission frame 223 and the body 10.

[0068] Figure 7 The following is a schematic diagram showing a partial structure of the housing of the self-moving cleaning device according to an embodiment of the present invention. Figure 8 for Figure 7 Enlarged view of part a.

[0069] Combined with Figure 6 , Attachment Figure 7 and attached Figure 8 As shown in , in some examples, the transmission frame 223 of this embodiment is provided with a first guide structure 2233, and accordingly, a second guide structure 112 is provided on the lower shell 11 of the body 10, and the first guide structure 2233 and the second guide structure 112 cooperate to guide the movement of the transmission frame 223 along the first direction.

[0070] In some examples, optionally, the first guide structure 2233 of the present embodiment includes a first guide plate 22331 and a second guide plate 22332 arranged relatively to each other along a second direction, the second direction being perpendicular to the first direction, and the second guide structure 112 includes a support boss 1121, and the support boss 1121 is located between the first guide plate 22331 and the second guide plate 22332.

[0071] The first guide plate 22331 and the second guide plate 22332 are parallel to each other and can be vertically installed on the transmission frame 223. The length direction of the first guide plate 22331 and the second guide plate 22332 extends along the first direction shown in the figure. The support boss 1121 can be a runway shape as shown in the figure, or a rectangle or other similar shapes. When the transmission frame 223 moves, the first guide plate 22331 and the second guide plate 22332 are limited by the support boss 1121 to guide the moving direction of the transmission frame 223.

[0072] In some examples, optionally, the second guide structure 112 of the present embodiment further includes a support bar 1122, the first guide plate 22331 is located between the support bar 1122 and the support boss 1121, the first guide plate 22331 is provided with a plurality of protrusions 223311 along the first direction, and a plurality of ribs 11221 are provided on the side of the support bar 1122 facing the first guide plate 22331 along the aforementioned first direction, a plurality of grooves 11222 are formed between the plurality of ribs 11221, the number of the grooves 11222 is greater than the number of the protrusions 223311, and the plurality of protrusions 223311 are located one-to-one in some of the plurality of grooves 11222.

[0073] The length direction of the support bar 1122 extends along the first direction shown in the figure. The support bar 1122 is not only used to support the first guide plate 22331 adjacent to it, but also a plurality of grooves 11222 are provided on the support bar 1122, and a plurality of protrusions 223311 are provided on the first guide plate 22331. The number of grooves 11222 is greater than the number of protrusions 223311. The plurality of protrusions 223311 convert the surface contact of the first guide plate 22331 with the support boss 1121 and the support bar 1122 into point contact, thereby reducing the friction between the first guide plate 22331 and the support boss 1121 and the support bar 1122. Of course, the protrusion 223311 can also be provided on the second guide plate 22332 of this embodiment to reduce the friction between the second guide plate 22332 and the support boss 1121.

[0074] Combined with the attachment again Figure 5 and attached Figure 6 As shown in , in some examples, optionally, the cleaning assembly 30 of this embodiment includes a second driving component 32, and the second driving component 32 is connected to the cleaning member 31 and is used to drive the cleaning member 31 to perform a cleaning action.

[0075] The second driving component 32 of this embodiment may include a second motor 321, and the rotation of the rotating shaft of the second motor 321 drives the cleaning member 31 to perform a cleaning action. For example, when the cleaning member 31 is a mop, the second motor 321 can drive the cleaning member 31 to rotate to mop the floor. Of course, the second driving component 32 of this embodiment can also be a vibration member (this embodiment is not shown in the figure), which drives the cleaning member 31 to mop the floor through vibration.

Accordingly, the telescopic drive component 20 of this embodiment is provided with a matching component. Figure 3 When the mating assembly is in the extended state, the telescopic drive assembly 20 is in the first position. Figure 2 When in the retracted state, the mating component is located at the second position, and the in-position detection component 40 is used to detect whether the mating component is in the first position or the second position.

[0077] When the mating assembly is in the first position, the cleaning member 31 moves to the extreme position outside the body 10. When the mating assembly is in the second position, the transmission frame 223 drives the cleaning member 31 to move to the inside of the receiving groove 111, and can abut against or have a gap with the side wall of the receiving groove 111.

[0078] The in-place detection component 40 can determine whether the cleaning member 31 has moved to the extreme position outside the body 10, ensuring the cleaning effect of the cleaning member 31 on the wall or the ground near the cabinet during cleaning, and can determine whether the cleaning member 31 is located at the extreme position in the accommodating groove 111, so that the two cleaning members 31 can form a complete cleaning surface when the self-mobile cleaning device 100 moves back and forth.

[0079] In some examples, optionally, the mating component of the present embodiment includes a first in-place detection member 41 and a second in-place detection member 42 installed at intervals in the body 10, and the telescopic drive component 20 includes a first mating structure 224 and a second mating structure 225 arranged at intervals; the mating component as a whole is in the first position, and the first mating structure 224 is connected to the first in-place detection member 41, and the mating component as a whole is in the second position, and the second mating structure 225 is connected to the second in-place detection member 42.

[0080] The first in-place detection member 41 and the second in-place detection member 42 of this embodiment can be existing contact sensors. When the first matching structure 224 abuts against the first in-place detection member 41, the first in-place detection member 41 transmits the signal of the detected first matching structure 224 to the controller inside the self-moving cleaning device 100 (not shown in the figure). When the second matching structure 225 abuts against the second in-place detection member 42, the second in-place detection member 42 transmits the signal of the detected second matching structure 225 to the controller inside the self-moving cleaning device 100, so that the controller determines whether the cleaning member 31 is retracted or extended to the preset position.

[0081] Of course, the structural form of the in-place detection component 40 of this embodiment is not limited to the above-mentioned first in-place detection component 41 and second in-place detection component 42. For example, the in-place detection component 40 can also be a distance sensor, which detects the distance from the transmission frame 223 or the transmission rack through infrared or other means. The controller of the self-mobile cleaning device 100 determines whether the cleaning component 31 is retracted or extended to the preset position based on the detected distance.

[0082] In some examples, optionally, when the transmission mechanism 22 of the present embodiment includes a first transmission gear 221, a first transmission rack 222, and a transmission frame 223, the first matching structure 224 mentioned above can be directly provided at one end of the first transmission rack 222, and the first matching structure 224 can be integrally formed with the first transmission rack 222, so that the first transmission rack 222 can realize the in-position detection function in addition to transmission, and has multiple uses in one. In addition, the second matching structure 225 can be formed on the second guide plate 22332 on the transmission frame 223, which can also improve the functionality of the second guide plate 22332.
