[0054] As shown in Figure 1 and Figure 3 The embodiment of the present application provides a rolling brush device 100, which is mainly used for cleaning equipment such as a sweeping robot, so that the rolling brush device 100 has a floating structure, and is convenient for obstacle crossing and cleaning. The rolling brush device 100 comprises a shell 110, a rolling brush assembly 120, an elastic soft body structure 130, a driving member 140 and a counterweight 150.

[0055] The shell 110 comprises a first end 1101 and a second end 1102 arranged oppositely along a first direction, and the shell 110 is provided with a containing cavity 113. A first opening 1121 in communication with the containing cavity 113 is formed on the side of the shell 110 facing the surface to be cleaned, and a second opening 1111 in communication with the containing cavity 113 is arranged on the inner side of the shell 110 facing the cleaning equipment, and the side of the shell 110 away from the second opening 1111 is hinged to the body (not shown in the figure) of the cleaning equipment, so as to facilitate the rotation of the shell 110 relative to the body;

[0056] It should be noted that the first direction is the length direction of the shell 110, which is also the axis direction of the roller brush 121. In addition, for the convenience of description, the cleaning surface is taken as an example of the ground, the side of the shell 110 away from the second opening 1111 is the first side, the side of the shell 110 provided with the second opening 1111 is the second side, and the first side and the second side are arranged on both sides in the width direction of the shell 110.

[0057] Referring to Figure 4 As shown, the roller brush assembly 120 is rotationally connected with the shell 110, the roller brush assembly 120 is located in the accommodating cavity 113, and the roller brush assembly 120 comprises a roller brush 121, a part of the roller brush 121 protrudes from the first opening 1121, and the driving member 140 drives the roller brush assembly 120 to rotate relative to the shell 110, so that the roller brush 121 sweeps the ground.

[0058] The driving member 140 is connected with the roller brush assembly 120 for driving the roller brush assembly 120 to rotate, and the driving member 140 is arranged at the first end 1101 of the shell 110. The counterweight 150 is arranged at the second end 1102 of the shell 110 to achieve equal weight at the first end 1101 and the second end 1102 of the shell 110, prevent the roller brush assembly 120 from tilting to one end, and avoid uneven cleaning. It should be noted that the driving member 140 can be a driving motor or a combination of a driving motor and a reduction box.

[0059] The elastic soft structure 130 is provided with a dust collection channel 133, and the elastic soft structure 130 is provided with a dust collection opening 1321 in communication with the dust collection channel 133, the dust collection opening 1321 is in communication with a dust collection bag (not shown in the figure) of the sweeping robot, so that the dust and garbage swept by the roller brush 121 pass through the dust collection channel 133 and the dust collection opening 1321 into the dust collection bag of the sweeping robot. The side of the elastic soft structure 130 away from the dust collection opening 1321 is connected at the second opening 1111, and the position of the elastic soft structure 130 with the dust collection opening 1321 is connected with the body of the cleaning device. Specifically, the first side of the shell 110 is hingedly connected with the body of the sweeping robot, and the second side of the shell 110 is fixedly connected with the body through the elastic soft structure 130.

[0060] The roller brush device 100 provided in the embodiments of this application connects the second side of the housing 110 to the body of the sweeping robot via an elastic soft structure 130. Simultaneously, the first side of the housing 110 is hinged to the body. Due to the rotation of the hinged position, the first side of the housing 110 can float upwards, and the elastic soft structure 130 can retract and deform, allowing the first side of the housing 110 to float upwards as well. This allows the roller brush device 100 to float completely on the body of the sweeping robot. Thus, when the sweeping robot encounters a protrusion or obstacle on the ground, the first side of the housing 110 floats and rises under the retraction of the elastic soft structure 130, and the second side of the housing 110 rises via the hinge connection between the housing 110 and the body. This allows the housing 110 and the roller brush assembly 120 installed within the housing 110 to float and rise as a whole, thereby overcoming obstacles. This eliminates the need for a lifting device to achieve obstacle-crossing functionality, and avoids the need for detection and identification to control the activation of a lifting device, thus improving its obstacle-crossing and obstacle-avoidance capabilities.

[0061] The roller brush device 100 of this embodiment achieves its floating function through the elastic soft structure 130 and the hinge method. Its structure is simple, easy to assemble, improves assembly efficiency, reduces product production costs, and enhances the product's market competitiveness. After passing over an obstacle, due to the gravity of the counterweight 150 installed at the second end 1102 of the housing 110 and the driving component 140 installed at the first end 1101, the housing 110 and the roller brush assembly 120 installed in the housing 110 naturally droop, thereby allowing the roller brush 121 to contact the cleaning surface and achieve the cleaning function.

[0062] like Figure 1 and Figure 2 As shown, in one embodiment, the roller brush device 100 further includes a linkage mechanism 160, which includes a first support 161, a second support 162, a first link 163, and a second link 164.

[0063] The first bracket 161 and the second bracket 162 are spaced apart and are respectively fixedly connected to the body;

[0064] One end of the first connecting rod 163 is hinged to the first bracket 161, that is, the end of the first connecting rod 163 near the first bracket 161 is hinged to the first bracket 161, and the other end of the first connecting rod 163 is hinged to the housing 110, that is, the end of the first connecting rod 163 away from the first bracket 161 is hinged to the housing 110.

[0065] One end of the second connecting rod 164 is hinged to the second support 162, that is, the end of the second connecting rod 164 close to the second support 162 is hinged to the second support 162, and the other end of the second connecting rod 164 is hinged to the shell 110, that is, the end of the second connecting rod 164 away from the second support 162 is hinged to the shell 110. Exemplarily, the shell 110 is respectively provided with a first lug and a second lug, the end of the first connecting rod 163 away from the first support 161 is hinged to the first lug, that is, a connecting hole is formed in the end of the first connecting rod 163 and the first lug, and the hinging of the two is realized by a pin shaft or a screw, and the end of the second connecting rod 164 away from the second support 162 is hinged to the second lug, that is, a connecting hole is formed in the end of the second connecting rod 164 and the second lug, and the hinging of the two is realized by a pin shaft or a screw. Of course, the hinging mode is not limited to this, and the hinging mode of the first connecting rod 163 and the second connecting rod 164 to the shell 110 can also be realized by other hinging structures, which will not be enumerated and described here.

[0066] Specifically, the length of the first connecting rod 163 is equal to the length of the second connecting rod 164. In this way, the second side of the shell 110 is more balanced when rotating, preventing tilting during the floating rising process.

[0067] Further, the connecting rod mechanism 160 further comprises a third connecting rod 165 and a fourth connecting rod 166.

[0068] The third connecting rod 165 is arranged in parallel with the first connecting rod 163, and one end of the third connecting rod 165 is hinged to the first support 161, and the other end of the third connecting rod 165 is hinged to the shell 110, so that the first connecting rod 163 and the third connecting rod 165 form a double connecting rod structure.

[0069] The fourth connecting rod 166 is arranged in parallel with the second connecting rod 164, and one end of the fourth connecting rod 166 is hinged to the second support 162, and the other end of the fourth connecting rod 166 is hinged to the shell 110, so that the second connecting rod 164 and the fourth connecting rod 166 form a double connecting rod structure.

[0070] The length of the first connecting rod 163, the length of the second connecting rod 164, the length of the third connecting rod 165, and the length of the fourth connecting rod 166 are all equal.

[0071] In this embodiment, the first connecting rod 163 and the third connecting rod 165 form a double connecting rod structure, so that the first connecting rod 163 and the third connecting rod 165 are respectively connected with the hinge points of the first support 161 and the hinge points of the shell 110, and the connecting lines of the hinge points form a parallelogram structure, so that the resistance is smaller when rotating, and the rotation is more smooth. Similarly, the second connecting rod 164 and the fourth connecting rod 166 also form a double connecting rod structure, so that the second connecting rod 164 and the fourth connecting rod 166 are respectively connected with the hinge points of the first support 161 and the hinge points of the shell 110, and the connecting lines of the hinge points form a parallelogram structure, so that the resistance is smaller when rotating, and the rotation is more smooth. In this way, the entire connecting rod mechanism 160 rotates more smoothly.

[0072] Continuing to refer to Figure 1 As shown in the drawings, in one embodiment, the first support 161 is arranged on the side opposite to the first connecting rod 163 and the second connecting rod 164, and the second support 162 is arranged on the side opposite to the second connecting rod 164 and the first connecting rod 163. In this way, the first support 161 and the second support 162 are arranged opposite to each other, and are both arranged on the inner side of the first connecting rod 163 and the second connecting rod 164, so as to reduce the occupied space.

[0073] The first support 161 is provided with a first positioning column 1611 and a first positioning hole 1612 in the second direction, the first positioning column 1611 and the first positioning hole 1612 are arranged at intervals, and the diameter of the first positioning column 1611 is smaller than the hole diameter of the first positioning hole 1612; the second support 162 is provided with a second positioning column 1621 and a second positioning hole 1622 in the second direction, the second positioning column 1621 and the second positioning hole 1622 are arranged at intervals, and the diameter of the second positioning column 1621 is smaller than the hole diameter of the second positioning hole 1622; wherein the second direction is perpendicular to the first direction. Specifically, the first support 161 is connected with the fuselage through the first positioning column 1611 and the first positioning hole 1612, such as a first connecting hole (not shown in the drawings) matched with the first positioning column 1611, a first connecting column (not shown in the drawings) matched with the first positioning hole 1612, a second connecting hole (not shown in the drawings) matched with the second positioning column 1621, and a second connecting column (not shown in the drawings) matched with the second positioning hole 1622. The first positioning column 1611 is inserted into the first connecting hole, the first connecting column is inserted into the first positioning hole 1612, so as to realize the connection between the first support 161 and the fuselage, and the second positioning column 1621 is inserted into the second connecting hole, and the second connecting column is inserted into the second positioning hole 1622, so as to realize the connection between the second support 162 and the fuselage. This connection mode is convenient for assembly and improves the assembly efficiency.

[0074] It should be noted that the second direction is the height direction of the shell 110, that is, the vertical direction. In addition, the diameter of the first positioning column 1611 is smaller than the hole diameter of the first positioning hole 1612, the first positioning column 1611 is located on the side of the first support 161 away from the shell 110, and the first positioning hole 1612 is arranged on the side of the first support 161 close to the shell 110.

The connecting line of the first positioning column 1611 and the second positioning column 1621 is crossly arranged with the first positioning hole 1612 and the second positioning hole 1622, so as to balance the structural strength of the first positioning column 1611, the first connecting hole, the first connecting column, the first positioning hole 1612, the second connecting column, the second positioning hole 1622, and the second positioning column 1621 and the second connecting hole.

[0075] As shown in the drawings, in one embodiment, the elastic soft structure 130 includes an arc-shaped soft body 131 and a flexible pipe 132. Figure 7 to Figure 9

[0076] As shown in the drawings, in one embodiment, the elastic soft structure 130 includes an arc-shaped soft body 131 and a flexible pipe 132. Figure 5 Specifically, as shown in the drawings, one side of the arc-shaped soft body 131 close to the second opening 1111 is formed with an open end, and a ring-shaped clamping groove 1311 is defined along the edge of the open end and clamped with the edge of the second opening 1111. In this way, the arc-shaped soft body 131 is connected with the shell 110 by clamping the ring-shaped clamping groove 1311 with the edge of the second opening 1111 of the shell 110, which facilitates the assembly of the elastic soft structure 130 and the shell 110 and improves the assembly efficiency.

[0077] The flexible pipe 132 is connected with the arc-shaped soft body 131 at one end close to the arc-shaped soft body 131, and is optionally integrally formed with the arc-shaped soft body 131. The flexible pipe 132 defines the dust collection channel 133 together with the arc-shaped soft body 131, and is provided with the dust collection opening 1321 at the other end away from the arc-shaped soft body 131. The other end of the flexible pipe 132 away from the arc-shaped soft body 131 is connected with the machine body. In this way, the arc-shaped soft body 131 and the flexible pipe 132 can both retract when encountering an obstacle, which facilitates the floating and rising of the roller brush device 100.

[0078] Further, the flexible pipe 132 is formed with a ring-shaped flange 1323 along the circumference of the dust collection opening 1321. In this embodiment, the ring-shaped flange 1323 is connected with the shell 110. Specifically, a plurality of riveting holes can be arranged along the circumference of the ring-shaped flange 1323, and the ring-shaped flange 1323 is connected with the shell 110 by riveting or the like.​

[0079] As shown in Figure 7 In one embodiment, the dust collecting port 1321 is isosceles trapezoidal. Of course, in other embodiments, the dust collecting port 1321 can also be rectangular, pentagonal, etc.

[0080] As shown in Figure 9 In the embodiment of the arc-shaped soft body 131, a plurality of reinforcing ribs 1312 are arranged in the annular clamping groove 1311. In this embodiment, the reinforcing ribs 1312 increase the structural strength of the arc-shaped soft body 131, avoid the arc-shaped soft body 131 from being broken due to repeated retraction, and improve the reliability of the product.

[0081] In the embodiment of the arc-shaped soft body 131 and the flexible pipe 132, the projection area of the flexible pipe 132 on the dust collecting port 1321 in the direction of the second opening 1111 is smaller than the surface area of the arc-shaped soft body 131. In this way, when the elastic soft body structure 130 deforms, the arc-shaped soft body 131 is more likely to deform, and due to its large area, it is balanced in force and is not easy to break.

[0082] As shown in Figure 1 and Figure 6 In any one of the above embodiments, the shell 110 includes an upper shell 111 and a bottom shell 112.

[0083] The driving member 140 and the counterweight member 150 are arranged in the upper shell 111, and the upper shell 111 is provided with the second opening 1111. The bottom shell 112 is connected with the upper shell 111 and defines the accommodating cavity 113, and the first opening 1121 is arranged in the bottom shell 112. In this embodiment, the shell 110 is composed of the upper shell 111 and the bottom shell 112, which are detachably connected, facilitating the assembly of the roller brush assembly 120.

[0084] In addition, it should be noted that the upper shell 111 and the bottom shell 112 are made of hard plastic material by injection molding, such as polyphenylene sulfide injection molding.

[0085] As shown in Figure 8As shown, in the embodiment of the arc-shaped soft body 131, the arc-shaped soft body 131 comprises a first edge 1313, a second edge 1314, a third edge 1315 and a fourth edge 1316 connected in sequence, the length of the first edge 1313 is less than the length of the third edge 1315, and the third edge 1315 is arranged close to the bottom shell 112. In this embodiment, the first edge 1313, the second edge 1314, the third edge 1315 and the fourth edge 1316 are arranged to form a trapezoidal structure, so that the first edge 1313 is closest to the hinge position of the linkage mechanism 160 and the shell 110, and the third edge 1315 is farthest from the hinge position of the linkage mechanism 160 and the shell 110. Therefore, since the force on the hinge position of the linkage mechanism and the shell 110 is the largest, by making the length of the third edge 1315 longer, the stress bearing area is increased, and damage to the arc-shaped soft body 131 is prevented.

[0086] Further, the reinforcing ribs 1317 are arranged at the connection regions of the third edge 1315 and the second edge 1314 and the third edge 1315 and the fourth edge 1316 to improve the connection strength and prevent the arc-shaped soft body 131 from being easily damaged.
