[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] The present application first proposes a side brush assembly 10, such as Figures 1 to 6 As shown, Figure 1 is a schematic structural diagram of an embodiment of a side brush assembly of the present application, Figure 2 yes Figure 1 A schematic top view of an embodiment, Figure 3 yes Figure 1 A side view schematically showing an embodiment, Figure 4 yes Figure 1 Another side view of the embodiment, Figure 5 yes Figure 1 A schematic side view of a partial structure of an embodiment, Figure 6 1 is a schematic diagram of the structure of the first state of the side brush assembly of the present application. The side brush assembly 10 includes a side brush frame 13, a first cleaning member 11, and a second cleaning member 12. The side brush frame 13 includes a main body 133, a first support portion 131, and a second support portion 132. The first end of the first support portion 131 is disposed on the main body 133; the first end of the second support portion 132 is disposed on the main body 133 and extends to the same side of the rotation plane of the main body 133 as the first support portion 131; the first cleaning member 11 is mounted on the second end of the first support portion 131; the second cleaning member 12 is mounted on the second end of the second support portion 132; Figure 2 As shown, a third distance d3 between the end of the first cleaning member 11 away from the main body 133 and the rotation axis A of the main body 133 is greater than a fourth distance d4 between the end of the second cleaning member 12 away from the main body 133 and the rotation axis A of the main body 133; Figure 3 , Figure 4 As shown, a third angle a3 between the end of the first cleaning member 11 away from the main body 133 and the rotation axis A is greater than a fourth angle a4 between the second cleaning member 12 and the rotation axis A.

[0021] The first cleaning member 11 and the second cleaning member 12 are components that can perform cleaning operations on the surface B to be cleaned. The main body 133 can drive the first support portion 131 and the second support portion 132 to rotate, thereby driving the first cleaning member 11 and the second cleaning member 12 to rotate to clean the surface B to be cleaned. For example, the first cleaning member 11 and the second cleaning member 12 can contact the surface B to be cleaned to perform cleaning operations such as scraping or sweeping the surface B to be cleaned. The first cleaning member 11 and the second cleaning member 12 can also perform cleaning operations on the surface B to be cleaned by spraying cleaning materials or other methods, which are not specifically limited. The surface B to be cleaned can be, for example, Figure 6 The plane shown may also be an uneven operating surface, etc., and is not specifically limited.

[0022] It should be noted that a third distance d3 between the end of the first cleaning member 11 away from one end of the main body 133 and the rotation axis A of the main body 133 is greater than a fourth distance d4 between the end of the second cleaning member 12 away from one end of the main body 133 and the rotation axis A of the main body 133. When the main body 133 drives the first cleaning member 11 and the second cleaning member 12 to rotate, the outer contour of the cleaning area formed by the first cleaning member 11 can be further away from the rotation axis A of the main body 133 relative to the outer contour of the cleaning area formed by the second cleaning member 12.

[0023] In an application scenario, such as Figure 6 As shown, in the first state, the first cleaning member 11 and the second cleaning member 12 are in contact with the surface to be cleaned B to achieve cleaning.

[0024] It should be noted that, in the present embodiment, the third angle a3 is greater than the fourth angle a4, and the specific angles of the third angle a3 and the fourth angle a4 are not limited. For example, the third angle a3 may be 60 degrees, 90 degrees, etc., and the fourth angle a4 may be 30 degrees, 45 degrees, etc. The third angle a3 being greater than the fourth angle a4 facilitates the realization that the third distance d3 is greater than the fourth distance d4. In an application scenario, due to the presence of the third angle a3 and the fourth angle a4, the main body 133 can be controlled to displace close to the surface to be cleaned B during rotation, so as to increase the contact area between the first cleaning member 11, the second cleaning member 12 and the surface to be cleaned B and the force acting on the surface to be cleaned B, thereby increasing the cleaning force.

[0025] The beneficial effect of the above arrangement is that the side brush assembly 10 includes a side brush frame 13, a first cleaning member 11, and a second cleaning member 12, and the first cleaning member 11 is installed at the second end of the first supporting portion 131, and the second cleaning member 12 is installed at the second end of the second supporting portion 132. The structure is simple, and the first cleaning member 11 and the second cleaning member 12 are easy to repair and replace, which can improve the user experience, and the arrangement of the two cleaning members can improve the dust removal effect of the side brush assembly 10, thereby improving the cleaning effect of the surface B to be cleaned; the second supporting portion 132 and the first supporting portion 131 extend toward the same side of the rotation plane of the main body 133, so that the second cleaning member 12 and the first cleaning member 11 extend toward the same side of the rotation plane of the main body 133, so that the second cleaning member 12 and the first cleaning member 11 can simultaneously clean the surface B to be cleaned; further, the third distance d3 between the end of the first cleaning member 11 away from one end of the main body 133 and the rotation axis A of the main body 133 is greater than the distance d4 between the second cleaning member 11 and the rotation axis A of the main body 133. The fourth distance d4 between the end of the cleaning member 12 away from one end of the main body 133 and the rotation axis A of the main body 133 can make the outer contour of the cleaning area formed by the first cleaning member 11 farther away from the rotation axis A of the main body 133 relative to the outer contour of the cleaning area formed by the second cleaning member 12, thereby expanding the range of the total cleaning area of ​​the side brush assembly 10; and the third distance d3 is greater than the fourth distance d4, which can improve the dust removal ability and cleaning effect of the side brush assembly 10 for the area to be cleaned close to the rotation axis A of the main body 133; further, the third angle a3 between the first cleaning member 11 and the rotation axis A is greater than the fourth angle a4 between the second cleaning member 12 and the rotation axis A, which is convenient for reducing the mutual interference between the first cleaning member 11 and the second cleaning member 12, and it is convenient to achieve that the third distance d3 is greater than the fourth distance d4, and the setting of the angle is convenient for increasing the force of the first cleaning member 11 and the second cleaning member 12 on the surface B to be cleaned when they contact the surface B to be cleaned, thereby improving the dust removal ability. Therefore, this embodiment can increase the cleaning range of the side brush assembly 10, improve the cleaning effect, and has a simple and reliable structure.

[0026] It should be noted that in the above settings, the third distance d3 is greater than the fourth distance d4, and the third angle a3 is greater than the fourth angle a4, which can be achieved by setting the structure of the side brush holder 13 and / or setting the shape and size of the first cleaning member 11 and the second cleaning member 12, without specific limitation.

[0027] Optionally, the structure of the side brush holder 13 is set. For example, the side brush holder 13 of the present embodiment includes a main body 133, a first support portion 131, and a second support portion 132. The first end of the first support portion 131 is arranged on the main body 133; the first end of the second support portion 132 is arranged on the main body 133 and extends to the same side of the rotation plane of the main body 133 as the first support portion 131; Figure 2As shown, a first distance d1 between the end of the second end of the first support portion 131 and the rotation axis A of the main body 133 is greater than a second distance d2 between the end of the second end of the second support portion 132 and the rotation axis A of the main body 133. Figure 3 , Figure 4 As shown, a first angle a1 between the second end of the first support portion 131 and the rotation axis A is greater than a second angle a2 between the second end of the second support portion 132 and the rotation axis A.

[0028] The beneficial effect of the above arrangement is that a first distance d1 between the end of the second end of the first supporting portion 131 and the rotation axis A of the main body 133 is greater than a second distance d2 between the end of the second end of the second supporting portion 132 and the rotation axis A of the main body 133, so as to facilitate the third distance d3 between the end of the first cleaning member 11 away from the main body 133 and the rotation axis A of the main body 133 to be greater than a fourth distance d4 between the end of the second cleaning member 12 away from the main body 133 and the rotation axis A of the main body 133, thereby facilitating the outer contour of the cleaning area formed by the first cleaning member 11 to be further away from the rotation axis A of the main body 133 relative to the outer contour of the cleaning area formed by the second cleaning member 12, so that The total cleaning area of ​​the side brush assembly 10 can be expanded; further, the first angle a1 between the second end of the first support portion 131 and the rotation axis A is greater than the second angle a2 between the second end of the second support portion 132 and the rotation axis A, so that the third angle a3 between the end of the first cleaning member 11 away from the main body 133 and the rotation axis A is greater than the fourth angle a4 between the second cleaning member 12 and the rotation axis A, thereby facilitating the reduction of mutual interference between the first cleaning member 11 and the second cleaning member 12, and facilitating the third distance d3 to be greater than the fourth distance d4, and the setting of the angle facilitates the improvement of the force of the first cleaning member 11 and the second cleaning member 12 on the surface B to be cleaned when they contact the surface B to be cleaned, thereby improving the dust removal ability. Therefore, this embodiment can improve the cleaning range of the side brush assembly 10, improve the cleaning effect, and has a simple and reliable structure.

[0029] Optionally, the structure of the side brush holder 13 is set. For example, a first distance d1 between the end of the second end of the first support portion 131 and the rotation axis A of the main body 133 is greater than a second distance d2 between the end of the second end of the second support portion 132 and the rotation axis A of the main body 133. Figure 3 , Figure 4 As shown, the first angle a1 between the second end of the first support portion 131 and the rotation axis A is greater than the second angle a2 between the second end of the second support portion 132 and the rotation axis A; and the first cleaning member 11 and the second cleaning member 12 are consistent in shape and size.

[0030] Specifically, in the above-mentioned setting, the shapes and sizes of the first cleaning member 11 and the second cleaning member 12 are consistent, that is, the setting of the third distance d3, the fourth distance d4, the third angle a3, and the fourth angle a4 is achieved only by setting the first distance d1, the second distance d2, the first angle a1, and the second angle a2. That is, the limitation that the third distance d3 is greater than the fourth distance d4 and the third angle a3 is greater than the fourth angle a4 can be achieved only by the structural setting of the side brush holder 13. Therefore, this setting method can reduce the complexity of user assembly, facilitate users to successfully install the first cleaning member 11 and the second cleaning member 12 on the first support part 131 and the second support part 132 respectively, reduce the risk of assembly errors, and improve the user experience.

[0031] In other embodiments, only the shapes or sizes of the first cleaning member 11 and the second cleaning member 12 may be different, so as to adjust the third distance d3, the fourth distance d4, the third angle a3, and the fourth angle a4 to meet different usage requirements, which is not specifically limited.

[0032] Optionally, in some application scenarios, the cleaning area formed by the first cleaning member and the cleaning area formed by the second cleaning member can be partially overlapped, connected or spaced, without specific limitation. For example, when the cleaning area formed by the first cleaning member and the cleaning area formed by the second cleaning member are partially overlapped, the cleaning force of the overlapping part can be increased, and the cleaning effect of the side brush can be improved; for another example, when the cleaning area formed by the first cleaning member and the cleaning area formed by the second cleaning member are connected, the total cleaning area of ​​the side brush can be increased, and the cleaning effect can be improved.

[0033] Optionally, in an application scenario, such as Figure 1 As shown, the first cleaning member 11 and the second cleaning member 12 are brush bodies. The above arrangement is convenient for improving the dust removal ability of the side brush assembly 10, thereby improving the cleaning effect of the side brush assembly 10 on the surface B to be cleaned.

[0034] Optionally, the side brush assembly 10 is applied to a cleaning robot, and the cleaning robot can clean the surface to be cleaned by using the side brush assembly 10 .

[0035] Alternatively, if Figure 5 As shown, a third extension length h3 of the end of the first cleaning member 11 away from the main body 133 in a direction parallel to the rotation axis A of the main body 133 is smaller than a fourth extension length h4 of the end of the second cleaning member 12 away from the main body 133 in the parallel direction.

[0036] Specifically, when the main body 133 drives the first cleaning member 11 and the second cleaning member 12 to approach the surface B to be cleaned, the second cleaning member 12 first contacts the surface B to be cleaned. When the side brush assembly 10 further approaches the surface B to be cleaned, the first cleaning member 11 and the second cleaning member 12 can contact the surface B to be cleaned at the same time. This arrangement is convenient for adjusting the cleaning method based on the application scenario. For example, when the cleaning requirement is low or the cleaning requirement range is small, only the second cleaning member 12 can be controlled to perform cleaning operations on the area to be cleaned on the surface B to be cleaned close to the main body 133. This can reduce the power consumption of the cleaning robot, and can achieve flexible adjustment of the cleaning operation area of ​​the side brush assembly 10, thereby improving the flexibility of use and applicability to multiple scenarios.

[0037] It should be noted that, in the above configuration, the third extension length h3 is smaller than the fourth extension length h4, which can be achieved by configuring the structure of the side brush holder 13 and / or configuring the shapes and sizes of the first cleaning member 11 and the second cleaning member 12, without any specific limitation.

[0038] Optionally, the structure of the side brush holder 13 is configured, for example, a first extension length h1 of the first support portion 131 in a direction parallel to the rotation axis A of the main body 133 may be configured to be smaller than a second extension length h2 of the second support portion 132 in the parallel direction.

[0039] like Figure 5 As shown, the setting of the first extension length h1 and the second extension length h2 facilitates the third extension length h3 of the first cleaning member 11 in a direction parallel to the rotation axis A of the main body 133 to be smaller than the fourth extension length h4 of the second cleaning member 12 in the parallel direction.

[0040] Optionally, the structure of the side brush holder 13 is configured. For example, a first extension length h1 of the first support portion 131 in a direction parallel to the rotation axis A of the main body portion 133 can be configured to be smaller than a second extension length h2 of the second support portion 132 in the parallel direction, and the first cleaning member 11 and the second cleaning member 12 are consistent in shape and size.

[0041] Specifically, in the above-mentioned setting, the first cleaning member 11 and the second cleaning member 12 are consistent in shape and size, that is, the setting of the third extension length h3 being less than the fourth extension length h4 is achieved only by setting the first extension length h1 to be less than the second extension length h2, that is, the limitation of the third extension length h3 being less than the fourth extension length h4 can be achieved only by the structural setting of the side brush holder 13. Therefore, this setting method can reduce the complexity of user assembly, and facilitates users to successfully install the first cleaning member 11 and the second cleaning member 12 on the first support part 131 and the second support part 132 respectively, thereby reducing the risk of assembly errors and improving the user's experience.

[0042] In other embodiments, only the shapes or sizes of the first cleaning member 11 and the second cleaning member 12 may be different, so as to adjust the third extension length h3 and the fourth extension length h4 to meet different usage requirements, which is not specifically limited.

[0043] Optionally, the control of the cleaning force can also be achieved by controlling the elastic strength of the first cleaning member 11 and the second cleaning member 12. In an application scenario, when the third extension length h3 is less than the fourth extension length h4, and the elastic strength of the first cleaning member 11 is less than or equal to the elastic strength of the second cleaning member 12, when the main body 133 drives the first cleaning member 11 and the second cleaning member 12 to contact the surface B to be cleaned, the deformation of the second cleaning member 12 is larger, so the interaction force between it and the surface B to be cleaned is greater, which can facilitate the targeted cleaning of the cleaning area formed by the second cleaning member 12 with stronger force; for another example, the third extension length h3 is less than the fourth extension length h4, and the elastic strength of the first cleaning member 11 can be controlled to be greater than the elastic strength of the second cleaning member 12, so that when the main body 133 drives the first cleaning member 11 and the second cleaning member 12 to contact the surface B to be cleaned, the cleaning force of the first cleaning member 11 on the surface B to be cleaned is greater than or equal to the cleaning force of the second cleaning member 12 on the surface B to be cleaned.

[0044] In other embodiments, the cleaning force can be adjusted by adjusting the magnitude relationship between the third extension length and the fourth extension length, and the magnitude relationship between the elastic strength of the first cleaning member and the elastic strength of the second cleaning member. For example, the third extension length can be controlled to be greater than or equal to the fourth extension length, and then the elastic strength of the first cleaning member and the elastic strength of the second cleaning member can be adjusted in a targeted manner, etc., and the specifics are not limited.

[0045] In other embodiments, according to the use requirements of the cleaning robot, the third extension length can be separately set to be greater than or equal to the fourth extension length, without limiting the elastic strength of the first cleaning member and the elastic strength of the second cleaning member.

[0046] Optionally, the adjustment of the size relationship between the third extension length and the fourth extension length can be achieved by controlling the size relationship between the first extension length and the second extension length and / or the length size of the first cleaning member and the length size of the second cleaning member.

[0047] Alternatively, if Figure 2 As shown, the difference between the third distance d3 and the fourth distance d4 is: 3-12 mm.

[0048] Specifically, Figure 2As shown, the third distance d3 is greater than the fourth distance d4, and the difference between the two is 3-12mm, for example, 3mm, 3.3mm, 4mm, 4.6mm, 5mm, 6.87mm, 7mm, 8.3mm, 9.5mm, 10mm, 11mm, 11.55mm or 12mm, etc., without specific limitation.

[0049] The beneficial effect of the above arrangement is that it can effectively expand the total cleaning range of the side brush assembly 10, reduce the cleaning blind spots of the cleaning robot (such as the area to be cleaned near the main body 133), and improve the cleaning effect.

[0050] Optionally, the difference between the third distance d3 and the fourth distance d4 may be set to 3-12 mm by setting the difference between the first distance d1 and the second distance d2.

[0051] This arrangement facilitates controlling the difference between the third distance d3 and the fourth distance d4 to be 3-12 mm, that is, the difference between the third distance d3 and the fourth distance d4 can be easily achieved to be 3-12 mm by structurally arranging the first support portion 131 and the second support portion 132, thereby improving the structural simplicity of the first cleaning member 11 and the second cleaning member 12 and reducing production costs.

[0052] Optionally, the difference between the third distance d3 and the fourth distance d4 is 5-10mm (for example, 5mm, 6.5mm, 7.2mm, 8mm, 10mm, etc.). This setting can reduce the cleaning blind spots of the cleaning robot (for example, the area to be cleaned near the main body 133) while reducing the overall structural size of the side brush assembly 10 and reducing the occupation of external space.

[0053] In other embodiments, the difference between the third distance d3 and the fourth distance d4 may also be 6-9 mm, 5.8-7 mm, etc., which is not specifically limited.

[0054] Optionally, according to the use requirements of the cleaning robot, the difference between the third distance d3 and the fourth distance d4 can be flexibly adjusted, and the specific details are not limited.

[0055] Optionally, the difference between the third distance d3 and the fourth distance d4 may be 5-10 mm, 6-9 mm or 5.8-7 mm, etc., by controlling the difference between the first distance d1 and the second distance d2.

[0056] In other embodiments, the third distance and the fourth distance may be adjusted by controlling the sizes of the first cleaning member and the second cleaning member.

[0057] Optionally, the difference between the third extension length h3 and the fourth extension length h4 is 3-12 mm.

[0077] Optionally, the first cleaning member 11 and the second cleaning member 12 may be detachably connected to the first supporting portion 131 and the second supporting portion 132 respectively by means of snap connection or the like, which is not specifically limited.

[0080] In other embodiments, the first support portion, the second support portion and the main body portion may also be detachably connected by snapping or other means or fixedly connected by bonding or other means, and the specific connection is not limited thereto.

[0081] Optionally, the side brush holder 13 includes a plurality of first support portions 131 and a plurality of second support portions 132 , and the plurality of first support portions 131 and the plurality of second support portions 132 are cross-connected and spaced apart.

[0082] The above-mentioned arrangement facilitates the installation of multiple first cleaning members 11 and multiple second cleaning members 12, and can improve the overall cleaning effect; further, the above-mentioned arrangement facilitates the realization of multiple first cleaning members 11 and multiple second cleaning members 12 being cross- and spaced apart, which can reduce the mutual interference between the first cleaning members 11 and the second cleaning members 12, and since the first cleaning members 11 and the second cleaning members 12 have different structural features (for example, different angles with the rotation axis A, etc.), this arrangement can improve the distribution uniformity of the first cleaning members 11 and the second cleaning members 12, and thus can improve the uniformity of the overall cleaning effect of the side brush assembly 10, and improve the user experience.

[0083] Optionally, the side brush holder 13 includes at least two first support portions 131 and at least two second support portions 132, and the at least two first support portions 131 and at least two second support portions 132 are cross-shaped and spaced apart, and the two first support portions 131 are centrally symmetrically arranged about the main body portion 133, which can improve the distribution uniformity of the first cleaning member 11, and thereby improve the uniformity of the cleaning effect.

[0084] Optionally, the two second support portions 132 are centrally symmetrically arranged with respect to the main body portion 133 , which can improve the distribution uniformity of the second cleaning members 12 , and further improve the uniformity of the cleaning effect.

[0086] The above-mentioned arrangement can make the cleaning area formed by the third cleaning member closer to the main body than the cleaning area formed by the second cleaning member, thereby further improving the dust removal ability and cleaning effect of the side brush assembly on the area to be cleaned close to the main body; further, in an application scenario, when the cleaning area formed by the third cleaning member does not completely overlap with the cleaning areas formed by the second cleaning member and the first cleaning member, the arrangement of the third cleaning member can also increase the cleaning range of the side brush assembly.

[0087] Optionally, the fifth extension length of the third cleaning member in a direction parallel to the rotation axis of the main body is greater than the fourth extension length, so as to further improve the flexibility of use of the side brush assembly. For example, only the third cleaning member can be controlled to perform cleaning operations on the surface to be cleaned, so as to achieve focused cleaning of the area to be cleaned that is closer to the rotation axis of the main body. Therefore, the lower limit of the cleaning range of the cleaning robot can be further narrowed, thereby improving the flexibility of use.

The first end of the first support portion 131 is arranged on the main body 133; the first end of the second support portion 132 is arranged on the main body 133, and extends to the same side of the rotation plane of the main body 133 as the first support portion 131; the first distance d1 between the end of the second end of the first support portion 131 and the rotation axis A of the main body 133 is greater than the second distance d2 between the end of the second end of the second support portion 132 and the rotation axis A of the main body 133, and the first angle a1 between the second end of the first support portion 131 and the rotation axis A is greater than the second angle a2 between the second end of the second support portion 132 and the rotation axis A.

[0092] The side brush holder 13 includes a first support portion 131 and a second support portion 132 arranged on the main body 133, which is convenient for installing the first cleaning member 11 and the second cleaning member 12; the second support portion 132 and the first support portion 131 extend toward the same side of the rotation plane of the main body 133, so that the second cleaning member 12 and the first cleaning member 11 extend toward the same side of the rotation plane of the main body 133, so that the second cleaning member 12 and the first cleaning member 11 can simultaneously clean the surface B to be cleaned; further, a first distance d1 between the end of the second end of the first support portion 131 and the rotation axis A of the main body 133 is greater than a second distance d2 between the end of the second end of the second support portion 132 and the rotation axis A of the main body 133, so as to realize that a third distance d3 between the end of the first cleaning member 11 away from one end of the main body 133 and the rotation axis A of the main body 133 is greater than a distance d3 between the end of the second cleaning member 12 away from one end of the main body 133 and the rotation axis A of the main body 133 The fourth distance d4 between the lines A, so that the outer contour of the cleaning area formed by the first cleaning member 11 is farther away from the rotation axis A of the main body 133 than the outer contour of the cleaning area formed by the second cleaning member 12, so that the range of the total cleaning area of ​​the side brush assembly 10 can be expanded; further, the first angle a1 between the second end of the first support portion 131 and the rotation axis A is greater than the second angle a2 between the second end of the second support portion 132 and the rotation axis A, so that the third angle a3 between the end of the first cleaning member 11 away from the main body 133 and the rotation axis A is greater than the fourth angle a4 between the second cleaning member 12 and the rotation axis A, so that the mutual interference between the first cleaning member 11 and the second cleaning member 12 is reduced, and the third distance d3 is greater than the fourth distance d4, and the setting of the angle is convenient to increase the force of the first cleaning member 11 and the second cleaning member 12 on the surface B to be cleaned when contacting the surface B to be cleaned, thereby improving the dust removal ability. Therefore, this embodiment can increase the cleaning range of the side brush assembly 10 and improve the cleaning effect.

[0093] The present application further proposes a cleaning robot, which includes the side brush assembly mentioned above.

[0094] The specific implementation and working principle of the side brush assembly can be found in the above embodiments and will not be described in detail here.

[0095] Optionally, the main body 133 is rotatably connected to the bottom plate of the cleaning robot, and the cleaning robot can drive the main body 133 to rotate. The main body 133 is rotatably connected to the bottom plate of the cleaning robot, so that the cleaning robot can drive the main body 133 to rotate, thereby driving the first cleaning member 11 and the second cleaning member 12 to rotate, thereby facilitating the cleaning operation.

[0096] Optionally, the side brush assembly also includes a lifting member, which is mounted on the bottom plate of the cleaning robot, and the lifting member is provided with a lifting surface; wherein the main body is used to connect with the driving member of the cleaning robot, and the main body can rotate along a first direction or a second direction relative to the lifting member, wherein the main body rotates along the first direction relative to the lifting member so that the first cleaning member and the second cleaning member move away from the surface to be cleaned along the lifting surface so as to separate from the surface to be cleaned; the main body rotates along the second direction relative to the lifting member so that the first cleaning member and the second cleaning member move close to the surface to be cleaned along the lifting surface so as to contact the surface to be cleaned; the first direction is opposite to the second direction.

[0097] The first cleaning member and the second cleaning member extend toward a side of the main body away from the bottom plate; the first direction may be counterclockwise or clockwise, and correspondingly, the second direction may be clockwise or counterclockwise.

[0098] The cleaning component of the present embodiment includes a side brush member and a lifting member, and the lifting member limits the movement of the side brush member. When the main body of the side brush member rotates relative to the lifting member along a first direction, the first cleaning member and the second cleaning member can move along the lifting surface away from the surface to be cleaned, so that the first cleaning member and the second cleaning member are separated from the surface to be cleaned, so that the first cleaning member and the second cleaning member can avoid objects that do not need to be cleaned on the surface to be cleaned; when the main body rotates relative to the lifting member along a second direction, the first cleaning member and the second cleaning member can move along the lifting surface close to the surface to be cleaned, so that the first cleaning member and the second cleaning member contact the surface to be cleaned and continue to clean the surface to be cleaned. That is, under the control of the driving member of the cleaning robot, the main body of the cleaning component of the present embodiment rotates relative to the lifting member along the first direction or the second direction, so that the first cleaning member and the second cleaning member can avoid objects on the surface to be cleaned and continue to complete the cleaning work after avoiding the objects, which can improve the user experience.

[0099] Among them, in some application scenarios, the first cleaning member and the second cleaning member are brush bodies, and the objects that do not need to be cleaned may be, for example, objects on the surface to be cleaned that affect subsequent cleaning. For example, the objects may be liquids, and the brush body may be wetted by the liquid. The wet brush body may affect subsequent cleaning. Based on this, the brush body of the present application can avoid the liquid on the surface to be cleaned, thereby solving the problem of the brush body of the cleaning robot being wetted by the liquid on the surface to be cleaned. Alternatively, the objects that do not need to be cleaned may be objects that are easily damaged by the brush body, for example, the objects may be carpets, and the brush body may damage the carpet during contact with the carpet. Based on this, the brush body of the present application can be separated from the surface to be cleaned, that is, separated from the contact surface with the carpet, thereby avoiding the situation where the brush body of the cleaning robot damages the carpet.

[0100] Optionally, the cleaning robot further comprises a driving member connected to the main body, and configured to drive the main body to rotate along the first direction or the second direction relative to the lifting member.

[0101] Different from the prior art, the side brush holder of the present application includes a first support part and a second support part arranged on the main body, which is convenient for installing the first cleaning member and the second cleaning member; the second support part and the first support part extend toward the same side of the rotation plane of the main body, which is convenient for the second cleaning member and the first cleaning member to extend toward the same side of the rotation plane of the main body, so as to realize that the second cleaning member and the first cleaning member can clean the surface to be cleaned at the same time; further, a first distance between the end of the second end of the first support part and the rotation axis of the main body is greater than a second distance between the end of the second end of the second support part and the rotation axis of the main body, so as to realize that a third distance between the end of the first cleaning member away from one end of the main body and the rotation axis of the main body is greater than a third distance between the end of the second cleaning member away from one end of the main body and the rotation axis of the main body. Four distances, so that the outer contour of the cleaning area formed by the first cleaning member is farther away from the rotation axis of the main body relative to the outer contour of the cleaning area formed by the second cleaning member, so that the range of the total cleaning area of ​​the side brush assembly can be expanded; further, the first angle between the second end of the first support portion and the rotation axis is greater than the second angle between the second end of the second support portion and the rotation axis, so that the third angle between the end of the first cleaning member away from the main body and the rotation axis is greater than the fourth angle between the second cleaning member and the rotation axis, so that it is easy to reduce the mutual interference between the first cleaning member and the second cleaning member, and it is easy to achieve that the third distance is greater than the fourth distance, and the setting of the angle is easy to increase the force of the first cleaning member and the second cleaning member on the surface to be cleaned when they contact the surface to be cleaned, thereby improving the dust removal ability. Therefore, this embodiment can increase the cleaning range of the side brush assembly and improve the cleaning effect.
