Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to sweeping devices and cleaning equipment. Background Technology

[0002] When cleaning equipment cleans a surface, it is usually necessary to control the working state of the cleaning components, such as rotation, lifting, or swinging. For example, when it is necessary to adjust the compaction of the cleaning components to adapt to different cleaning needs, the lifting component can adjust the height of the cleaning components in a timely manner; when it is necessary to avoid obstacles or stop the cleaning work, the lifting component will retract the cleaning components to avoid unnecessary contact and damage.

[0003] In related technologies, lifting components typically generate relative motion through threaded engagement, thereby converting rotational motion into axial lifting motion, which in turn drives or abuts the cleaning components to control their lifting. This lifting component occupies a large axial space, reducing the cleaning equipment's maneuverability in low-ceilinged spaces, and limiting the lifting height of the cleaning components due to space constraints. Utility Model Content

[0004] To address or partially address the problems existing in the related technologies, this application provides a cleaning device and cleaning equipment that can reduce space occupation, improve maneuverability, and increase the lifting height of the cleaning components.

[0005] The first aspect of this application provides a cleaning device, including a cam, a translational member, and a cleaning member;

[0006] The cam is configured to rotate clockwise or counterclockwise and is in transmission cooperation with the translational component, used to drive the translational component to move linearly in a preset direction when rotating;

[0007] The translational member has a transmission part on the side facing the cleaning member; the cleaning member has a mating part that drives and cooperates with the transmission part at one end near the translational member, and the mating part is rotatably configured to convert the linear motion of the transmission part into the rotational motion of the mating part.

[0008] In one embodiment, the translational member is provided with an abutment groove, the cam is at least partially received in the abutment groove, and at least a portion of its outer peripheral surface is formed as a contact surface for contacting the abutment groove;

[0009] When the cam rotates, the contact surface moves along the groove wall of the abutment groove to push the translational member to move in a preset direction.

[0010] In one embodiment, the groove wall of the abutment groove includes an adapter groove and a first contact portion and a second contact portion disposed opposite to each other. The adapter groove connects the first contact portion and the second contact portion respectively, and the first contact portion and the second contact portion intersect the preset direction respectively.

[0011] The contact surface of the cam moves from the first contact portion along the adapter groove to the second contact portion, or from the second contact portion along the adapter groove to the first contact portion, so as to push the first contact portion or the second contact portion, causing the translational member to move linearly in the preset direction.

[0012] In one embodiment, the gap between the first contact portion and the second contact portion is d, the maximum radial dimension of the cam is x, and the maximum radius is r;

[0013] Where x ≤ d < 2r.

[0014] In one implementation,

[0015] The gap d between the first contact portion and the second contact portion is equal to the maximum radial dimension x of the cam.

[0016] In one embodiment, the transmission part includes a rack, and the mating part includes a gear.

[0017] In one embodiment, the transmission part includes a protrusion, and the mating part includes a groove; or,

[0018] The transmission part includes a groove, and the mating part includes a protrusion.

[0019] In one embodiment, the translational member is provided with a sliding portion in the preset direction;

[0020] The cleaning device further includes a housing for housing the translational member, and the inner wall of the housing is provided with a fixing part along the preset direction. The fixing part is matched with the sliding part to support the translational member and allow the sliding part to move linearly along the fixing part.

[0021] In one embodiment, the cleaning component includes a side brush, one end of which is used to clean the surface to be cleaned, and the other end of which is fixedly connected to the mating part, so that when the mating part rotates, the side brush rotates synchronously.

[0022] A second aspect of this application provides a cleaning device, including the cleaning apparatus described above.

[0023] The technical solution provided in this application can include the following beneficial effects: The cleaning device of this application includes a cam, a translational member, and a sweeping member; the cam is configured to rotate clockwise or counterclockwise and is driven to cooperate with the translational member, used to drive the translational member to move linearly in a preset direction when rotating; the translational member has a transmission part on the side facing the sweeping member; the sweeping member has a mating part at one end near the translational member that is driven to cooperate with the transmission part, and the mating part is rotatably configured to convert the linear motion of the transmission part into the rotational motion of the mating part. By converting the rotational motion of the cam into horizontal linear motion through the translational member, and then converting the linear motion of the transmission part into the rotational motion of the mating part through the transmission part and the mating part, the cleaning member rotates as a whole around the mating part as the rotation center, thereby increasing the maximum lifting height and eliminating the need for longitudinal movement, which can reduce the longitudinal dimension and improve the passability of the cleaning equipment.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0039] See Figures 1-3This embodiment provides a cleaning device 100, including a cam 10, a translational member 20, and a cleaning member 30. The cam 10 is configured to rotate clockwise or counterclockwise and is in transmission cooperation with the translational member 20, used to drive the translational member 20 to make linear motion in a preset direction when rotating. The translational member 20 is provided with a transmission part 21 on the side facing the cleaning member 30. The cleaning member 30 is provided with a mating part 31 that is in transmission cooperation with the transmission part 21 at one end near the translational member 20, and the mating part 31 is rotatably configured to convert the linear motion of the transmission part 21 into the rotational motion of the mating part 31.

[0040] Since the cam 10 is a rotating component with a protruding part, when the cam 10 rotates clockwise or counterclockwise, its radial dimension in the preset direction will decrease and increase regularly. Therefore, when the translation component 20 is engaged with the cam 10, the translation component 20 will achieve linear motion due to the change in the push stroke of the cam 10 in the preset direction.

[0041] When the translational component 20 moves linearly, the transmission part 21 moves linearly synchronously. The mating part 31 engages with the transmission part 21 and is rotatably mounted. Therefore, when the transmission part 21 moves linearly, it will drive the mating part 31 to rotate, thereby driving the entire cleaning component to rotate, causing the cleaning component to flip, for example, flipping in the direction F shown in the figure or flipping in the opposite direction of F. When the cleaning component flips, for example, the part in contact with the surface to be cleaned rises, thereby separating from the surface to be cleaned, or falls, thereby contacting the surface to be cleaned, or further increases the pressure acting on the surface to be cleaned, so as to improve the cleaning effect.

[0042] The cleaning component 30 can be used to clean the surface to be cleaned, such as the ground, and the preset direction can be parallel to the surface to be cleaned, such as the horizontal direction.

[0043] In this embodiment, the rotational motion of the cam 10 with varying stroke is converted into the linear motion of the translational member 20, and then the linear motion is converted into the flipping motion of the cleaning member. This achieves the lifting and lowering of the cleaning member while increasing the maximum lifting height. Since it does not require longitudinal movement, the longitudinal dimension can be reduced, which is beneficial to improving the passability of the cleaning equipment 200. Furthermore, by setting the mating position of the mating part 31 and the transmission part 21, the pressure acting on the surface to be cleaned can be increased, thereby improving the cleaning effect.

[0044] refer to Figure 4 In one embodiment, the translation member 20 is provided with an abutment groove 22, the cam 10 is at least partially housed in the abutment groove 22, and at least part of its outer peripheral surface 11 is formed as a contact surface for contacting the abutment groove 22; when the cam 10 rotates, the contact surface moves along the groove wall of the abutment groove 22 to push the translation member 20 to move in a preset direction.

[0045] The abutment groove 22 can be a groove with an opening on one side. When the cam 10 rotates, its outer peripheral surface 11 with the maximum radius can form a contact surface, contacting the groove wall of the abutment groove 22. Since the thrust of the contact surface in the preset direction changes with the rotation of the cam 10, the groove wall of the abutment groove 22 will be subjected to thrust in different directions of the contact surface, thus achieving linear motion in the preset direction. However, the abutment groove 22 can also be configured without an opening, and there is no specific limitation on this.

[0046] refer to Figures 4-6 In one embodiment, the groove wall of the abutment groove 22 includes an adapter groove 25 and a first contact portion 23 and a second contact portion 24 disposed opposite to each other. The adapter groove 25 connects the first contact portion 23 and the second contact portion 24 respectively, and the first contact portion 23 and the second contact portion 24 intersect with a preset direction respectively. The contact surface of the cam 10 moves from the first contact portion 23 along the adapter groove 25 to the second contact portion 24, or from the second contact portion 24 along the adapter groove 25 to the first contact portion 23, so as to push the first contact portion 23 or the second contact portion 24, so that the translation member 20 makes a linear movement in the preset direction.

[0047] The adapter groove 25 can match the shape of the cam 10 so that when the contact surface of the cam 10 passes through the adapter groove 25, there is no abutting force between it and the adapter groove 25, thus avoiding the adapter groove 25 from limiting the cam 10, thereby enabling the contact surface of the cam 10 to rotate through the adapter groove 25 and switch between the first contact part 23 and the second contact part 24.

[0048] In this embodiment, the first contact portion 23 and the second contact portion 24 do not coincide with the preset direction and may have a preset included angle of less than 90 degrees. In this embodiment, the first contact portion 23 and the second contact portion 24 may be arranged in parallel and perpendicular to the preset direction.

[0049] When the contact surface of the cam 10 moves from the first contact portion 23 along the adapter groove 25 to the second contact portion 24, or from the second contact portion 24 along the adapter groove 25 to the first contact portion 23, due to the change in the push stroke, a force perpendicular to the first contact portion 23 or the second contact portion 24 will be generated, that is, a force in the preset direction, which will push the first contact portion 23 or the second contact portion 24 to realize the translation member 20 moving in the preset direction.

[0050] refer to Figure 6 In one embodiment, the gap between the first contact portion 23 and the second contact portion 24 is d, the maximum radial dimension of the cam 10 is x, and the maximum radius is r; wherein, x≤d<2r.

[0051] The gap between the first contact portion 23 and the second contact portion 24 can be the distance between the first contact portion 23 and the second contact portion 24 in a preset direction. For example, the preset direction is K, and the direction K can be perpendicular to the plane of the first contact portion 23 and the second contact portion 24.

[0052] Among them, the maximum radial dimension of cam 10 refers to the maximum length of cam 10 as a whole on the plane of rotation, and the maximum radius refers to the distance from the center of rotation to the farthest end of the protrusion.

[0053] In this embodiment, to ensure a large push stroke of cam 10 and to prevent cam 10 from spinning freely in the gap, x ≤ d < 2r is set. For ease of understanding, for example, the distance from the rotation center O of cam 10 to the first contact part 23 in the preset direction is m, and the distance to the second contact part 24 is n, where m + n = d.

[0054] Since r is the maximum radius, in order for the cam 10 to make contact with the first contact part 23 and the second contact part 24 respectively, it is necessary to set r > m and r > n. Therefore, 2r > m + n, that is, 2r > d.

[0055] Since x is the maximum radial dimension, it includes the maximum radius r and the extension line passing through the center of rotation to the other end of the outer circumferential surface 11.

[0056] In one embodiment, x < d, the cam 10 can separate from the second contact portion 24 when it contacts the first contact portion 23, and can separate from the first contact portion 23 when it contacts the second contact portion 24. In this embodiment, to achieve self-locking of the cleaning member 30, a self-locking mechanism can be added to limit the cam 10 so that the cleaning member 30 maintains a constant height when subjected to external force.

[0057] In one embodiment, the gap d between the first contact portion 23 and the second contact portion 24 is equal to the maximum radial dimension x of the cam 10, i.e., x = d. When the cam 10 reaches its maximum thrust, it simultaneously abuts against the first contact portion 23 and the second contact portion 24 in a preset direction. At this time, since the contact points of the first contact portion 23, the second contact portion 24, and the cam 10 coincide in the preset direction, the first contact portion 23 and the second contact portion 24 can only apply abutting force to the cam 10 in the preset direction, and cannot form torque to drive the cam 10 to rotate. Therefore, self-locking is achieved, preventing the cleaning component 30 from flipping when subjected to external force. It can lock the lifting or lowering height of the cleaning component 30, which is beneficial for controlling the cleaning component 30.

[0058] In other embodiments, d < x can also be set. Before the cam 10 rotates clockwise or counterclockwise to the maximum push stroke in the preset direction, it simultaneously abuts against the limit with the first contact part 23 and the second contact part 24 and cannot continue to rotate. Although the translation member 20 has movement in the preset direction, the movement stroke is small, which makes the cooperation stroke of the cooperation part 31 of the cleaning member 30 also small, which may be detrimental to the lifting and lowering of the cleaning member 30. However, it should be noted that even if d < x, if the difference between the two is not large, lifting and lowering can still be achieved. Moreover, when x and d are close, after the cleaning part 30 is subjected to external force, the first contact part 23 or the second contact part 24 will exert a thrust on the cam 10. Since the values ​​of x and d are close, the cam 10 almost abuts against the first contact part 23 or the second contact part 24 in a preset direction. The torque formed by the force of the first contact part 23 or the second contact part 24 cannot overcome the friction between the cam 10 and the first contact part 23 and the second contact part 24, and can also make the cam 10 self-lock, so that the cleaning part 30 cannot be overturned by external force. However, this is only an example, and the specific values ​​are not limited in this embodiment.

[0059] refer to Figure 2 and Figure 5 In one embodiment, the cam 10, the translation member 20 and the cleaning member 30 are distributed from top to bottom, and the transmission part 21 is provided on the bottom surface of the translation member 20.

[0060] The cam 10 can be connected to a drive shaft, which passes through the cam 10, for example, through a through hole 12 provided in the cam 10. The through hole 12 and the drive shaft are coaxially arranged. The cam 10 rotates around the axis of the drive shaft, driving the translational member 20 to move linearly in a preset direction. The transmission part 21 is provided on the bottom surface of the translational member 20, and the mating part 31 can be provided at one end of the cleaning member. Thus, through the transmission part 21 and the mating part 31, the cleaning member is rotated around the mating part 31 as the rotation center.

[0061] In one embodiment, the cleaning device 100 includes a bearing 50, which can be integrally formed with a cam. A drive shaft passes through a coaxial through hole 12 of the bearing 50 and the cam 10, which can drive the bearing 50 and the cam 10 to rotate synchronously.

[0062] refer to Figure 2 and Figure 3 In one embodiment, the transmission part 21 includes a rack and the mating part 31 includes a gear.

[0063] The rack moves linearly in a preset direction, driving the meshing gear to rotate. The rotation of the gear causes the cleaning component to flip, that is, the cleaning component flips with the axis of the gear as the center of flipping, thereby lifting or lowering, so as to achieve separation, contact and pressure from the ground.

[0064] In one embodiment, the transmission part 21 includes a protrusion and the mating part 31 includes a groove; or, the transmission part 21 includes a groove and the mating part 31 includes a protrusion.

[0065] The protrusion or groove of the transmission part 21 moves in a preset direction, driving the groove or protrusion of the mating part 31 to rotate. The principle is the same as that of the rack and pinion, and will not be described in detail here.

[0066] In one embodiment, the translational member 20 is provided with a sliding portion 26 in a preset direction; the cleaning device 100 also includes a housing 40, which is used to house the translational member 20, and the inner wall surface of the housing 40 is provided with a fixing portion in a preset direction. The fixing portion is matched with the sliding portion 26 to support the translational member 20 and to allow the sliding portion 26 to move linearly along the fixing portion.

[0067] The housing 40 can be an outer shell with a cavity formed by installing an upper housing and a lower housing, and the housing 40 has an opening so that the cleaning member 30 can extend from inside the housing 40 to outside the housing 40.

[0068] The sliding part 26 of the translation member 20 and the fixed part of the housing 40 are arranged in a preset direction. The fixed part is at least housed in the sliding part 26, so that after the translation member 20 is pushed by the cam 10 in the preset direction, it slides on the fixed part through the sliding part 26 and moves in the preset direction.

[0069] In addition to supporting the translation member 20 and guiding it in a preset direction, the fixing part also limits the translation member 20 in other directions, preventing it from moving in other directions and improving its stability.

[0070] In one embodiment, the sliding part 26 can be a groove, and the fixing part can be a boss. However, the sliding part 26 can also be a boss, and the fixing part can be a groove, or other mating forms, as long as the sliding part 26 can move along the fixing part in a preset direction.

[0071] refer to Figures 1-3 In one embodiment, the cleaning component 30 includes a side brush, one end of which is used to clean the surface to be cleaned, and the other end is fixedly connected to the mating part 31 so that the side brush rotates synchronously when the mating part 31 rotates.

[0072] The side brush extends from the mating part 31, with one end fixed to the mating part 31 and the other end provided with bristles for cleaning the surface to be cleaned. When the mating part 31 rotates under the transmission action of the transmission part 21 of the translational member 20, it drives the side brush to rotate. The bristles of the side brush flip around the mating part 31 as the center of rotation, thereby lifting off the ground or contacting the ground, realizing the lifting and lowering of the side brush. Corresponding to the aforementioned application function implementation device embodiment, this application also provides a cleaning device and a corresponding embodiment.

[0073] Figure 7 This is a schematic block diagram of the system structure of the cleaning equipment shown in the embodiments of this application.

[0074] See Figure 7 This embodiment also provides a cleaning device 200, which includes the cleaning device 100 as described above.

[0075] The cleaning equipment 200 can be a sweeping robot, a mopping robot, a sweeping and mopping robot, a window cleaning robot, etc., and this embodiment does not make specific limitations.

[0076] The cleaning device 200 provided in this embodiment is equipped with the above cleaning device 100. Since the cleaning device 100 occupies less longitudinal space, the longitudinal dimension of the cleaning device 200 can be reduced, achieving a compact design. This is beneficial for cleaning in low and narrow areas, improving passability. Furthermore, since the cleaning component 30 of the cleaning device 100 has a larger lifting range, the cleaning effect can also be improved.
