[0046] Mobile robots (such as sweeping robots) are equipped with a roller brush module, which cleans the floor.

[0047] In existing roller brush operation modules, the main roller brush component is axially fixed at one end and can rotate, while the other end is limited. This allows the roller brush to rotate along the axial direction at one end, resulting in unilateral floating. Unilateral floating prevents the roller brush operation module from adhering well to the ground, leading to poor cleaning performance.

[0048] This utility model proposes an operation module.

[0049] Please see Figure 2 , Figure 4 In one embodiment of this utility model, the working module includes a first seat 100 and a roller brush mechanism 200. The first seat 100 is provided with a mounting cavity 110, and the mounting cavity 110 has a cavity opening 112; furthermore, the first seat 100 is formed by combining two components.

[0050] Furthermore, the roller brush mechanism 200 includes a second seat 210 and a roller brush portion 220 disposed on the second seat 210. The second seat 210 is located in the mounting cavity 110. Comparing the structures of the second seat 210 and the mounting cavity 110, when the structure of the mounting cavity 110 is significantly larger than the second seat 210, the second seat 210 can completely fall out of the cavity opening 112 of the mounting cavity 110 when the cleaning device is lifted from the ground, and the second seat 210 can remain within the mounting cavity 110 when the cleaning device is placed on the ground. When the second seat 210 is configured with a smaller lower half and a larger upper half, the smaller lower half of the second seat 210 can pass through the mounting cavity 110, while the larger upper half can rest against the cavity wall of the mounting cavity 110. When the cleaning device is lifted from the ground, the larger upper half restricts the second seat 210 from completely falling out of the mounting cavity 110. Furthermore, the roller brush portion 220 can form a cleaning area, and the structure of the cleaning area varies depending on the structure of the roller brush portion. In some embodiments, when the roller brush portion 220 is configured as a tracked roller brush, that is, when the roller brush is configured as a single roller brush, the tracked roller brush can form an approximately rectangular cleaning area during cleaning. In this case, the cleaning area of ​​the roller brush portion 220 can be relatively large compared to a single roller brush. Further, in some embodiments, the roller brush portion 220 is provided with at least two roller brushes 221, and the two roller brushes 221 are arranged side by side (see...). Figure 6It should be noted that the roller brush section 220, composed of two roller brushes 221 arranged side by side, can form an approximately rectangular cleaning area during cleaning. This results in a relatively large cleaning area compared to a single roller brush 221. In some embodiments, the roller brush section 220 can also be configured with three roller brushes 221, which are also arranged side by side. The second base 210 has a first mounting portion 211 and a second mounting portion 212 at opposite ends. In some embodiments, the first mounting portion 211 and the second mounting portion 212 are configured as a circular shaft structure or a circular hole structure fixed to the second base 210. The first mounting part 211 is connected to the first seat 100 via a swing arm 300, and the second mounting part 212 is connected to the first seat 100 via another swing arm 300. One end of the swing arm 300 is hinged to the first seat 100, and the other end of the swing arm 300 is hinged to the second seat 210. The hinge position of at least one end of the swing arm 300 can be tilted. It should be noted that in this embodiment, there are two swing arms 300. One swing arm 300 is hinged to the first mounting part 211 of the second seat 210, and the other swing arm 300 is hinged to the second mounting part 212 of the second seat 210. In this embodiment, the tilting position of at least one end of the swing arm 300 can be categorized into the following examples. First, the hinge position of the swing arm 300 tilts to the first seat 100, but not to the hinge position of the second seat 210. The second type is where the hinge position of the swing arm 300 with the first seat 100 does not deflect, but the hinge position with the second seat 210 deflects. The third type is where the hinge positions of the swing arm 300 with both the first seat 100 and the second seat 210 deflect.

[0051] When the second seat 210 encounters resistance from the ground in any direction, it can deflect, causing the roller brush 221 to deflect as well. It should be noted that the resistance from the ground can be either direct or indirect. Direct resistance can occur in several ways: first, during the movement of the cleaning device and its working module, the inclined protrusion 111 on the ground contacts the second seat 210, causing it to be obstructed; second, during the movement of the cleaning device and its working module, the inclined protrusion 111 on the ground contacts the second seat 210, causing it to be obstructed. Indirect resistance can occur through the transmission of the roller brush 221. Furthermore, depending on the deflection at different hinge positions, the deflection of the second seat 210 can be categorized into several cases. The first scenario involves the swing arm 300 deflecting at its hinge position with the first seat 100, but not with its hinge position with the second seat 210. In this case, both the second seat 210 and the swing arm 300 can deflect at their hinge positions with the first seat 100. The second scenario involves the swing arm 300 not deflecting at its hinge position with the first seat 100, but deflecting at its hinge position with the second seat 210. In this case, the second seat 210 can deflect at its hinge position with the second seat 210. The third scenario involves the swing arm 300 deflecting at its hinge positions with both the first seat 100 and the second seat 210. In this case, the second seat 210 can deflect at its hinge position with the second seat 210, and the swing arm 300 can also deflect at its hinge position with the first seat 100.

[0052] By employing a first mounting portion and a second mounting portion respectively provided at opposite ends of the second seat 210, with the first mounting portion 211 connected to the first seat 100 via a swing arm 300 and the second mounting portion 212 connected to the first seat 100 via another swing arm 300, one end of the swing arm 300 is hinged to the first seat 100 and the other end is hinged to the second seat 210, and the hinge position of at least one end of the swing arm 300 can be tilted, so that when one end of the second seat 210 tilts up, the other end can also tilt up, thus allowing both ends of the second seat 210 to have a certain degree of floating. Compared with the prior art where only one side tilts up, this allows for better contact with the ground, thereby solving the technical problems existing in the prior art.

[0053] Furthermore, when the roller brush section 220 consists of two roller brushes 221 arranged side by side, the second seat 210 can be tilted to allow the approximately rectangular cleaning area to fit well with the ground. For example, when there is a carpet on the ground, when the cleaning equipment moves the working module, one side of the second seat 210 is first resisted by the carpet. At this time, the second seat 210 tilts. Depending on the direction of the resistance experienced by the second seat 210, when the resistance experienced by the second seat 210 is perpendicular to the axis of the roller brush 221, the front side of the second seat 210 can be completely lifted, which simultaneously lifts the roller brush 221 located on the front side completely. This allows the roller brush 221 located on the front side to fall onto the carpet after being fully lifted, thus creating a better fit between the roller brush 221 and the carpet. When the resistance experienced by the second seat 210 is tilted relative to the axis of the roller brush 221, only one corner of the approximately rectangular cleaning area formed by the two roller brushes 221 will lift first, while the other corner will not lift. The corner that does not lift can cooperate with the two corners on the other side to form an approximately triangular cleaning area. The triangular cleaning area can also make the roller brush 220 fit better with the ground, further improving the cleaning effect.

[0054] In this embodiment, the second seat 210 is connected to the first seat 100 via two swing arms 300, and at least one hinged end of each swing arm 300 can swing, meaning that both ends of the seat can swing, allowing the second seat 210 to float in multiple directions. It should be noted that when the roller brush section 220 uses two side-by-side roller brushes 221, the multi-directional floating during operation ensures that both roller brushes 221 touch the ground simultaneously, guaranteeing an effective cleaning area, and preventing one from touching the ground while the other does not. This problem does not exist with a single roller brush.

[0055] In one embodiment, the swing arm 300 may have the following structure: one end of the swing arm 300 is provided with a first mounting hole 310, and the other end is provided with a second mounting hole 320. The first mounting hole 310 is rotatably connected to the first base 100. In some embodiments, the first base 100 is provided with a first mounting shaft that cooperates with the first mounting hole 310 of the swing arm 300, that is, the first mounting shaft is rotatably connected to the first mounting hole 310, and the second mounting hole 320 is rotatably connected to the second base 210. In this case, the second base is provided with a second mounting shaft, and the second mounting shaft is rotatably connected to the second mounting hole 320. That is, the first mounting portion 211 and the second mounting portion 212 on the second base 210 are configured as the second mounting shaft, wherein at least one rotatable connection position is a clearance fit, and the clearance is configured as a first clearance 600. In some embodiments, the two ends of the swing arm 300 may be provided with a round shaft structure. In this case, the first base 100 is provided with a round hole structure, and the first mounting portion 211 and the second mounting portion 212 on the second base 210 are configured as round hole structures. It should be noted that, by using the clearance fit between the mounting hole and the mounting shaft to achieve the sway between the second seat 210 and the swing arm 300 or between the swing arm 300 and the first seat 100, the second seat 210 can be connected to the swing arm 300. Furthermore, the clearance fit between the mounting hole and the round shaft structure facilitates the connection and assembly of the swing arm 300 with the first seat 100 and the second seat 210, reduces assembly difficulty, and also reduces the production precision and production cost of both. Furthermore, the first mounting shaft and the second mounting shaft are provided with rotating mounting positions. The length of the rotating mounting position is greater than the wall thickness of the swing arm 300. It should be noted that the length of the rotating mounting position is greater than the wall thickness of the swing arm 300, which means that the length of the rotating mounting position is greater than the depth of the mounting holes (first mounting hole and second mounting hole). When the swing arm 300 swings, since the length of the rotating mounting position is greater than the depth of the mounting hole, the rotating mounting position can limit the deflection angle of the swing arm 300 to a certain extent. In this way, the swing arm 300 can be prevented from detaching from the rotating mounting position, that is, the swing arm 300 can be prevented from detaching from the mounting shaft.

[0056] In one embodiment, a portion of the swing arm 300 is located in the mounting cavity 110, the first seat 100 is provided with a mounting groove 120, and another portion of the swing arm 300 is located in the mounting groove 120. A second gap 800 is provided between the two opposing groove walls of the swing arm 300 and the mounting groove 120, and between the swing arm 300 and the cavity wall of the mounting cavity 110. Further, referring to... Figure 7To enable the second seat 210 to swing more effectively within the mounting cavity 110, a protrusion 111 is formed on the cavity wall of the mounting cavity 110. The protrusion 111 is located between the two ends of the swing arm 300, and a second gap 800 is provided between the protrusion 111 and the swing arm 300. In other words, a second gap 800 is provided between the protrusion 111 on the cavity wall of the mounting cavity 110 and the swing arm 300. Thus, the protrusion 111 reduces the contact area between the second seat 210 and the cavity wall of the mounting cavity 110, reducing friction and facilitating better swinging of the second seat 210.

[0057] In one embodiment, reference Figure 5 , Figure 7 The first gap 600 is 0.05mm-4mm, and the second gap 800 is 0.05mm-6mm. Within this gap range, the structure of the working module can be more compact, while also allowing the second seat 210 to swing. It should be noted that when the first gap 600 is less than 0.05mm and the second gap 800 is less than 0.05mm, the space left for the second seat 210 is limited, making the second seat 210 sluggish when swinging and causing it to float unevenly in multiple directions. However, if the first gap 600 is greater than 4mm and the second gap 800 is greater than 6mm, the gap is too large, which would cause the second seat 210 to contact the first seat 100. Understandably, if the gap is too large, the floating range of the second seat 210 will also increase, making it easier for the second seat 210 to contact the first seat 100, thus affecting the floating effect of the second seat 210.

[0058] In one embodiment, reference Figure 2 , Figure 3The roller brush mechanism 200 further includes a first guide portion 230 disposed on the second seat 210, wherein the first guide portion 230 is disposed on the side of the second seat 210 facing the ground, and the first guide portion 230 is provided with a first guide surface 231, which is disposed around the outer side of the second seat 210. It should be noted that the side of the first guide surface 231 closest to the ground is inclined toward the inside of the second seat 210. Furthermore, the second seat 210 can indirectly receive the resistance of the ground through the first guide surface 231. That is to say, when the cleaning equipment moves the working module, the resistance generated by the protrusion 111 on the ground can be indirectly transmitted to the second seat 210 through the first guide surface 231. At this time, the second seat 210 is resisted and swayed, thereby causing the roller brush 221 to sway. Since the side of the first guide surface 231 closest to the ground is inclined toward the interior of the second seat 210, when the first guide surface 231 is continuously subjected to resistance, the resistance can generate a vertically upward separation, thereby lifting the second seat 210, so that the second seat 210 is located above the protrusion 111 on the ground.

[0059] In one embodiment, reference Figure 2 , Figure 3 The first guide portion 230 is configured as a ring structure, and the first guide surface 231 is located on the outer side of the ring structure. That is, the first guide surface 231 is also configured as a ring structure. In this case, the first guide surface 231 can enclose and form an inverted truncated pyramidal spatial structure. Furthermore, when the working module follows the cleaning equipment forward, backward, left, or right and encounters the protrusion 111, the first guide surface 231 on the ring structure can cause the second seat 210 to be lifted by resistance. In some embodiments, a protective frame is also provided on the first guide portion 230, in which case the first guide surface 231 is located on the outer side of the protective shell. Furthermore, the protective frame can be configured as a rust-free metal material, which can improve the durability of the first guide surface 231.

[0060] In one embodiment, reference Figure 3 , Figure 4The first seat 100 is also provided with a second guide portion 240, which has a second guide surface 241. The second guide surface 241 can transfer the resistance it receives to the first guide surface 231. This arrangement is to place part of the structure on the first guide surface 231 on the first seat 100, so as to avoid the structure of the first guide surface 231 being too large, which would result in the structure of the first guide portion 230 being too large and affecting the space of the roller brush 221. In other words, placing part of the structure of the first guide surface 231 on the first seat 100 can make the structure of the first guide portion 230 more compact. When the more compact first guide portion 230 is installed on the second seat 210, it can reduce the space occupied by the second seat 210, ensuring that the second seat 210 has enough space for the roller brush portion 220, thereby avoiding affecting the space of the roller brush 221. In this embodiment, the guide surface on the working module is divided into two parts, with one part set in the first guide section 230 and the other part set on the first base. This allows the working module to have a large guide area while avoiding affecting the space of the roller brush 221.

[0061] In one embodiment, reference Figure 2 The second guide portion 240 is configured as two, and the extension direction of the two second guide portions 240 is perpendicular to the rotation axis of the roller brush portion 220. They are respectively arranged on both sides of the roller brush mechanism 200. This is so that when the cleaning equipment drives the working module to turn left and right and encounters the protrusion 111, the larger guide surface (the combination of the first guide surface 231 and the second guide surface 241) can easily lift the second seat 210.

[0062] In one embodiment, reference Figure 3 The second guide portion 240 is configured as a protruding elongated structure 111, wherein the second guide surface 241 is provided on the protruding elongated structure 111, which makes the second guide portion 240 more complete, and thus makes the second guide surface 241 on the second guide portion 240 more complete. In some embodiments, the second guide portion 240 may be configured as a multi-segment protruding structure 111.

[0063] In one embodiment, reference Figure 4 The swing arm 300 is provided with multiple bending sections 330. These bending sections allow the swing arm 300 to better fit with the first seat 100 and the second seat 210, making the working module more compact. At the same time, the multiple bending sections also give the swing arm 300 better stability. When the second seat 210 sways, the multiple bending sections of the swing arm 300 can distribute the force appropriately, avoiding concentration in one place. Appropriate force distribution makes the swing arm 300 more stable and reduces the risk of deformation.

[0064] In one embodiment, the roller brush mechanism 200 further includes a universal structure (not shown), and the swing arm 300 is connected to the first seat 100 and the second seat 210 through the universal structure. The swing arm 300 can be connected to the first seat 100 and the second seat 210 through the universal structure to realize the hinge of the swing arm 300 with the first seat 100 and the second seat 210, and at least one hinge position can realize the swing.

[0065] In one embodiment, the structure of the mounting cavity 110 is larger than that of the second seat 210. To prevent the second seat 210 from falling out of the mounting cavity 110 when the cleaning device is picked up, a limiting portion 112 is provided on the cavity wall of the mounting cavity 110 (see...). Figure 8 The roller brush mechanism 200 further includes an abutment portion 250 disposed on the second seat 210 (see...). Figure 8 The abutting part 250 can be mounted on the limiting part 112. By mounting the abutting part 250 on the limiting part 112, the second seat 210 can be prevented from falling out of the mounting cavity 110.

[0066] In one embodiment, in order to counteract the force exerted on the ground by the two roller brushes 221 during cleaning, the two roller brushes 221 rotate in opposite directions. The rotation direction of the two roller brushes 221 can be towards the middle of the two roller brushes 221 or towards the outside of the two roller brushes 221. In this way, when the cleaning equipment moves the working module, the reaction force generated by the working module can be reduced on the cleaning equipment, avoiding the situation where the cleaning equipment moves too fast or too slow.
