[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] It should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "back", "side", "circumferential" and the like in the present invention indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the words "first", "second" and the like are only used to distinguish multiple components or structures with the same or similar structures, and do not represent any special limitation on the arrangement order or connection relationship.

[0042] Please refer to Figures 1 to 7The embodiment of the present invention provides a side brush device 100 for a sweeping machine, which is used to be assembled on a chassis (not shown in the figure) of a sweeping robot (not shown in the figure) to clean dust, debris and other debris on the floor. The side brush device 100 for a sweeping machine includes: a rotating shaft 1, a side brush seat 2, a rotating and telescopic side brush arm 3 and a telescopic control component 4.

[0043] Among them, the rotating shaft 1 is transmission-connected with the driving member to receive the torque of the driving member. The side brush seat 2 is fixedly connected to the rotating shaft 1 so as to rotate around the rotating shaft 1 under the drive of the rotating shaft 1. The side brush seat 2 has a winding assembly chamber a inside, and the side of the side brush seat 2 has an opening b connecting the winding assembly chamber a with the outside. The rotating telescopic side brush arm 3 has a first end 31 and a second end 32, the first end 31 is arranged in the winding assembly chamber a, and the second end 32 extends from the opening b. The telescopic control component 4 is arranged on the outside of the rotating shaft 1, and can fix or loosen the first end 31 of the rotating telescopic side brush arm 3 and the side brush seat 2. That is, the telescopic control component 4 can control the first end 31 of the rotating telescopic side brush arm 3 and the side brush seat 2 to be in a first state of fixed connection, or in a second state of loosening.

[0044] When the side brush holder 2 is released, the side brush holder 2 can be rotated to adjust the length of the rotating telescopic side brush arm 3 extending out of the side brush holder 2. When the first end 31 of the rotating telescopic side brush arm 3 is in the second state of separation and release from the side brush holder 2, please refer to Figure 3 Taking the counterclockwise rotation of the side brush holder 2 as an example, since the first end 31 of the rotating telescopic side brush arm 3 is stationary and the side brush holder 2 is rotating, there is a speed difference between the two. Therefore, the side brush holder 2 can retract the rotating telescopic side brush arm 3 into the retracting assembly cavity a, thereby reducing the length of the rotating telescopic side brush arm 3 extending out of the opening b. Please refer to Figure 2 Similarly, when the rotating telescopic side brush arm 3 is rolled up, if the side brush seat 2 rotates clockwise, the rotating telescopic side brush arm 3 rolled up in the rolling assembly cavity a can be thrown out and extended from the opening b of the side brush seat 2, thereby increasing the length of the rotating telescopic side brush arm 3 extending out of the opening b.

[0045] When fixed, the rotating telescopic side brush arm 3 and the side brush holder 2 can rotate synchronously. When the first end 31 of the rotating telescopic side brush arm 3 is in a first state of fixed connection with the side brush holder 2, at this time, since the rotation speeds of the side brush holder 2 and the rotating telescopic side brush arm 3 are the same, the length of the rotating telescopic side brush arm 3 extending out of the opening b remains unchanged.

[0046] Since the side brush assembly has a rotating telescopic side brush arm 3 with a first end 31 disposed in the winding assembly cavity a of the side brush seat 2 and a second end 32 extending from the opening b of the side brush seat 2, and a telescopic control assembly 4 disposed outside the rotating shaft 1, which can fix or release the first end 31 of the rotating telescopic side brush arm 3 with the side brush seat 2, and adjust the length of the rotating telescopic side brush arm 3 extending from the side brush seat 2 when the side brush seat 2 rotates; when cleaning the side edge, the side brush cleaning area can be increased by extending the length of the rotating telescopic side brush arm 3 extending from the side brush seat 2 to ensure cleaning to the right-angle corner position; and when cleaning in an I-shaped shape, the side brush cleaning area can be reduced by shortening the length of the rotating telescopic side brush arm 3 extending from the side brush seat 2. In this way, the side brush assembly has the advantages of adjustable side brush cleaning area and good cleaning effect at the right-angle corner position.

[0047] In order to realize the control of the connection state between the first end 31 of the rotating telescopic side brush arm 3 and the side brush holder 2 by the telescopic control component 4, optionally, please refer to Figure 4 In this embodiment, the telescopic control assembly 4 includes an electromagnet 41, an armature and a permanent magnet 43. The electromagnet 41 is concentrically arranged on the outer side of the rotating shaft 1 and located on the upper side of the side brush seat 2. The armature and the first end 31 of the rotating telescopic side brush arm 3 are fixedly matched, and can drive the first end 31 to be adsorbed on the electromagnet 41. That is, when the electromagnet 41 is energized to generate a magnetic field, the fixed armature and the first end 31 of the rotating telescopic side brush arm 3 can be adsorbed. That is, when the electromagnet is energized, the first end 31 of the rotating telescopic side brush arm 3 is released from the side brush seat 2. The permanent magnet 43 is fixedly matched in the winding assembly cavity a of the side brush seat 2 and is located on the lower side of the first end 31. When the electromagnet 41 is powered off, the rotating telescopic side brush arm 3 and the armature are adsorbed and fixed in the side brush seat 2 by the permanent magnet 43. It can be understood that after the electromagnet 41 absorbs the first end 31 of the rotating telescopic side brush arm 3, after the side brush seat 2 is rotated to adjust the length of the rotating telescopic side brush arm 3 extending out of the side brush seat 2, the electromagnet 41 is powered off, and the first end 31 of the rotating telescopic side brush arm 3 is absorbed and fixed by the permanent magnet, so that the length of the rotating telescopic side brush arm 3 extending out of the side brush seat 2 can be maintained at the adjusted length.

[0048] Optionally, see Figure 4 and Figure 5In the present embodiment, the side brush seat 2 comprises a side brush base 21 and a side brush cover 22. The side brush seat 2 is bowl-shaped. The outer periphery of the side brush seat 2 is provided with a fixed-length brush arm 5 extending outward. The center of the side brush seat 2 has a connecting shaft 211 fixedly connected to the rotating shaft 1. Specifically, the connecting shaft 211 has a plug-in slot c, the rotating shaft 1 is inserted into the plug-in slot c, and is fixed by fasteners. The side brush cover 22 is covered on the bowl mouth of the side brush base 21, and the side brush cover 22 and the side brush base 21 cover the inside to form the above-mentioned winding assembly chamber a. The center of the side brush cover 22 has a through hole o to facilitate the passage of the rotating shaft 1, the connecting shaft 211, the armature, and the first end 31 of the rotating and telescopic side brush arm 3. The side brush base 21 and the side brush cover 22 cover to form the above-mentioned opening b.

[0049] In order to prevent the rotating telescopic side brush arm 3 from shrinking too much when adjusting the length of the extended side brush holder 2, a mechanical positioning structure is designed to ensure the shrinkage length. Figure 7 In this embodiment, a positioning column 221 is provided at the bottom of the side brush cover 22 , and the positioning column 221 is used to limit and fix the first end 31 of the rotating telescopic side brush arm 3 between the rotating telescopic side brush arm 3 and the side brush seat 2 .

[0050] Optionally, see Figure 4 and Figure 6 In this embodiment, the first end 31 of the rotating telescopic side brush arm 3 has an annular boss 311, which is sleeved on the connecting shaft 211; the armature is an iron ring 42 sleeved and fixedly connected to the outer periphery of the annular boss 311 of the first end 31. In this way, when the electromagnet is energized, the armature can drive the first end 31 of the rotating telescopic side brush arm 3 to move upward and be attracted and fixed on the electromagnet.

[0051] In order to make the process of extending or retracting the rotating side brush arm into the winding assembly cavity a of the side brush holder 2 smoother, optionally, please refer to Figure 5 In this embodiment, the opening b extends along the circumference of the side brush holder 2, and the height of the opening b gradually increases from one end to the other end. That is, while the first end 31 of the rotating side brush arm rises or falls along the connecting shaft 211, the rotating side brush arm rolls up or extends.

[0052] Optionally, see Figure 2 and Figure 3In this embodiment, the fixed-length brush arm 5 and the rotating telescopic side brush arm 3 both extend outward along the involute of the side brush base 21. In this way, when the side brush base 2 rotates along the involute direction, it encounters less resistance. Of course, in other embodiments, the fixed-length brush arm 5 and the rotating telescopic side brush arm 3 may also extend radially along the side brush base 21, which is not specifically limited here. Optionally, the side brush device 100 of the sweeper has two fixed-length brush arms 5 and one rotating telescopic side brush arm 3. The two fixed-length brush arms 5 and the rotating telescopic side brush arm 3 are equally spaced and distributed on the periphery of the side brush base 2. Of course, in other embodiments, the number of fixed-length brush arms 5 and rotating telescopic side brush arms 3 is not limited thereto, and may also be only a plurality of rotating telescopic side brush arms 3, or a combination of a plurality of fixed-length brush arms 5 and a plurality of rotating telescopic side brush arms 3, which is not specifically limited here.

[0053] Optionally, see Figure 2 and Figure 3 In this embodiment, the free ends of the fixed-length brush arm 5 and the rotating telescopic side brush arm 3 have slots e for fixing the bristles 7. That is, the bristles 7 are detachably fixed in the slots e of the fixed-length brush arm 5 and the rotating telescopic side brush arm 3. In this way, when the bristles 7 are damaged, they can be removed by the bristles 7, avoiding the need to replace the entire brush strip.

[0054] In order to allow the rotating telescopic side brush arm 3 to be rolled up in the rolling assembly cavity a of the side brush holder 2, optionally, please refer to Figure 6 In this embodiment, the rotating telescopic side brush arm 3 is a brush strip arm made of a flexible material, for example, the rotating telescopic side brush arm 3 is made of a soft rubber material. In order to make it easier for the rotating telescopic side brush arm 3 to be rolled up in the rolling assembly chamber a, optionally, the side wall of the rotating telescopic side brush arm 3 near the first end 31 has bending notches d arranged at equal intervals, and the bending notches d make the rotating telescopic side brush arm 3 bend at the bending notches d when the side brush holder 2 rotates to be rolled up in the rolling assembly chamber a. That is, since the rotating telescopic side brush arm 3 at the bending notch d position is thinner, it is easier to bend there, so that the rotating telescopic side brush arm 3 is easier to rotate and be accommodated in the rolling assembly chamber a of the side brush holder 2.

[0055] In order to provide torque to the shaft 1 and facilitate the assembly of the shaft 1 and the electromagnet 41, optionally, please refer to Figure 1 and Figure 4In this embodiment, the side brush device 100 of the sweeping machine also includes a side brush box assembly 6. The side brush device 100 of the sweeping machine can be fixedly connected to the chassis of the robot body (not shown in the figure) through the side brush box assembly 6. The side brush box assembly 6 includes a side brush box housing 61, a drive motor 62 and a transmission gear 63. The rotating shaft 1 is rotatably configured on the side brush box housing 61. The electromagnet 41 is fixedly mounted on the side brush box housing 61 and is located on the outside of the rotating shaft 1. The transmission gear 63 is configured in the side brush box housing 61. Specifically, the side brush box housing 61 includes a side brush box lower cover 611 and a side brush box upper cover 612 that cover each other. The driving member is a drive motor 62 that is fixedly mounted on the side brush box housing 61 and is transmission-connected to the rotating shaft 1 through the transmission gear 63.

[0056] Another aspect of the embodiment of the present invention provides a sweeping robot (not shown in the figure), including a robot body, the chassis of the robot body is equipped with the sweeping machine side brush device 100 as described above, and part of the cleaning area of ​​the sweeping machine side brush device 100 is located outside the contour range of the robot body. Since the sweeping robot has all the structures and connection relationships of the sweeping machine side brush device 100, it has all the advantages of the sweeping machine side brush device 100, which will not be described in detail here.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
