[0043] In view of the above problems, the embodiment of the present application provides a transmission mechanism which can optimize the control mode, improve compatibility and facilitate the functional expansion of the cleaning device.

[0044] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0045] Referring to Figure 1 and Figure 2 The embodiment provides a cleaning device 100, which comprises a cleaning assembly 10, a driving mechanism 20 and a tangential mechanism 30. The driving mechanism 20 comprises a first transmission group (not shown in the figure), a second transmission group (not shown in the figure) and a driving member 21, the driving member 21 is switchably connected to the first transmission group or the second transmission group, and is used for inputting driving force to the first transmission group or the second transmission group; the first transmission group and the second transmission group are connected to the cleaning assembly 10 respectively, and the first transmission group and the second transmission group are configured to output driving force in opposite directions; the tangential mechanism 30 is connected with the driving member 21, and is used for cutting off the connection between the driving member 21 and the first transmission group, and connecting the driving member 21 to the second transmission group.

[0046] Among them, the driving mechanism 20 is configured to rotate in a forward direction or a reverse direction, for example, rotate in a clockwise direction or rotate in a counterclockwise direction, so as to output driving force in a forward direction or a reverse direction.

[0047] Among them, the first transmission group and the second transmission group can be arranged from the driving member 21 to the cleaning assembly 10, and the first transmission group and the second transmission group can have partially shared transmission components, but can also be arranged independently, and the embodiment does not make specific limitation.

[0048] For ease of understanding, one working condition of the cleaning device 100 is described below.

[0049] The driving member 21 rotates forward, and is in driving connection with the first transmission group. The first transmission group does not change the output direction of the driving force of the driving member 21, so that the cleaning assembly 10 rotates forward. When it is necessary to change the rotation direction of the cleaning assembly 10, the driving member 21 is driven by the tangential assembly 30 to be disconnected from the first transmission group and connected with the second transmission group. Since the driving force output by the driving member 21 is forward, the second transmission group changes the driving force direction to be reverse, so that the cleaning assembly 10 reverses. Therefore, the cleaning assembly 10 can be controlled to rotate forward or reverse when the rotation direction of the driving member 21 does not change, which optimizes the control mode of the cleaning assembly 10 and enhances the functionality of the cleaning device 100, and is conducive to the intelligent design of the cleaning device 100.

[0050] Reference Figure 2 and Figure 3 In one embodiment, the driving member 21 includes a driving shaft 22 which is movable in the axial direction and rotatable about the axis. The driving shaft 22 is in connection with the first transmission group at a first preset position in the axial direction, and is in connection with the second transmission group at a second preset position in the axial direction. The tangential mechanism 30 is connected with the driving shaft 22, and is used to drive the driving shaft 22 to switch between the first preset position and the second preset position in the axial direction.

[0051] The driving shaft 22 is arranged to be movable in the axial direction, for example, to ascend or descend along the axis, and rotatable about the axis, for example, to rotate clockwise or counterclockwise.

[0052] The first transmission group and the second transmission group are distributed in the axial direction of the driving shaft 22, so that the driving shaft 22 can be connected with the first transmission group or the second transmission group when ascending or descending in the axial direction.

[0053] The tangential mechanism 30 can be connected with the driving shaft 22 by means of key connection, pin connection, clamping, etc., and can drive the driving shaft 22 to ascend or descend synchronously when ascending or descending in the direction parallel to the axial direction of the driving shaft 22, so as to switch the driving shaft 22 between the first preset position and the second preset position.

[0054] Reference Figure 3 In one embodiment, the tangential mechanism 30 includes a tangential motor 33, a tangential transmission group 32 and a tangential action member 31. The tangential transmission group 32 is connected with the tangential motor 33 and the tangential action member 31 respectively, and is used to transmit the power of the tangential motor 33 to the tangential action member 31, so as to drive the tangential action member 31 to move in the direction parallel to the axial direction of the driving shaft 22. The tangential action member 31 extends at least partially to the driving shaft 22, and is connected with the driving shaft 22.

[0055] The tangential motor 33 drives the tangential transmission set 32 to rotate, and the tangential transmission set 32 controls the tangential action member 31 to move in a direction parallel to the axial direction of the driving shaft 22. For example, when the tangential motor 33 rotates forward, the tangential transmission set 32 rotates forward, and the tangential action member 31 rises, thereby synchronously driving the driving shaft 22 to rise. When the tangential motor 33 reverses, the tangential transmission set 32 reverses, and the tangential action member 31 descends, thereby synchronously driving the driving shaft 22 to descend, but not limited to this.

[0056] Reference Figure 3 and Figure 4 In one embodiment, the tangential transmission set 32 includes a tangential rotating member 320, a lead screw 323, and a damping member 324. The tangential rotating member 320 is connected to the tangential motor 33, and is provided with a threaded hole. The lead screw 323 is arranged in the threaded hole and is provided with an external thread. The damping member 324 is connected to both sides of the axis of the lead screw 323 and is used to abut against the tangential rotating member 320. The axis of the lead screw 323 is parallel to the axis of the driving shaft 22.

[0057] The external thread of the lead screw 323 and the internal thread of the tangential rotating member 320 are matched. When the tangential rotating member 320 rotates under the driving of the tangential motor 33, a torque is output to the lead screw 323, so that the lead screw 323 is subjected to the damping force of the damping member 324, and the lead screw 323 and the tangential rotating member 320 are relatively rotated, and then the tangential rotating member 320 is lifted along the axis of the lead screw 323.

[0058] Since the axis of the lead screw 323 is parallel to the axis of the driving shaft 22, and the tangential action member 31 is connected to the tangential rotating member 320, when the tangential rotating member 320 is lifted along the axis of the lead screw 323, the tangential action member 31 is lifted, which is equivalent to being lifted along the axis of the driving shaft 22, and then the driving shaft 22 is lifted.

[0059] The tangential action member 31 can extend from the tangential rotating member 320 towards the driving shaft 22. The circumferential direction of the driving shaft 22 can be provided with a protrusion, a gear or a fixed rod, etc. The tangential action member 31 abuts against the driving shaft 22 to drive the driving shaft 22 to move along the axial direction. The tangential action member 31 can also be connected to the driving shaft 22 by a key connection, a pin connection, etc., which is not limited in the embodiment.

[0060] Reference Figure 5 In one embodiment, the damping member 324 includes a sliding part 3240, which is configured to synchronously rotate under the driving of the tangential rotating member 320.

[0061] The sliding part 3240 has a preset damping force. When the tangential rotating part 320 rotates on the screw rod 323, the damping part 324 is fixed with the screw rod 323, the tangential rotating part 320 can move in the axial direction, for example, rise or fall, when the tangential rotating part 320 moves to the stroke limit of the screw rod 323, the sliding part 3240 of the damping part 324 abuts, at this time, if the damping part 324 and the screw rod 323 continue to be fixed, the tangential rotating part 320 cannot continue to rotate, which may cause the tangential motor 33 to be blocked. In the embodiment, the preset damping force of the sliding part 3240 is less than the torque of the tangential rotating part 320, so that the sliding part 3240 can rotate synchronously under the driving of the tangential rotating part 320 when the tangential rotating part 320 abuts, and then the sliding part 3240, the screw rod 323 and the tangential rotating part 320 rotate synchronously, avoiding the risk of motor blocking.

[0062] In one embodiment, the tangential rotating part 320 includes a tangential gear 321 and a shaft sleeve 322, the tangential gear 321 is sleeved outside the shaft sleeve 322, the shaft sleeve 322 is provided with a threaded hole, the screw rod 323 is arranged in the threaded hole and is screwed with the shaft sleeve 322; the shaft sleeve 322 includes a clamping base and a protruding column, the threaded hole penetrates through the protruding column and the clamping base along the axis; wherein the tangential gear 321 is sleeved on the protruding column, the radius of the protruding column is less than the radius of the clamping base and the tangential gear 321 respectively, so that a gap for clamping the tangential action part 31 is formed between the clamping base and the tangential gear 321.

[0063] The tangential gear 321 can be provided with an inner hole for connecting with the protruding column. The outer circumferential surface of the protruding column is fixed with the gear, and the inner wall surface of the threaded hole is screwed with the screw rod 323.

[0064] The protruding column and the tangential gear 321 can be provided with matched limiting fixing parts. After the tangential gear 321 is installed on the protruding column, the tangential gear 321 is fixed with the protruding column and is limited in the axial direction of the protruding column, so that the end surface of the tangential gear 321 close to the clamping base can form a gap with the surface of the clamping base close to the tangential gear 321. When the tangential action part 31 is arranged in the gap, the tangential gear 321 and the clamping base abut the opposite sides of the tangential action part 31, so as to fix the tangential action part 31.

[0065] Reference Figures 3 to 5 In one embodiment, the tangential action part 31 includes a lifting plate 310, the lifting plate 310 includes a first abutting surface and a second abutting surface in the axial direction of the driving shaft 22, and the lifting plate 310 is provided with a through hole; the first abutting surface abuts the tangential gear 321, the second abutting surface abuts the clamping base, and the through hole is arranged through the protruding column.

[0066] The first abutting surface and the second abutting surface of the lifting plate 310 can be arranged perpendicularly to the axis of the driving shaft 22 and the lead screw 323, and the first abutting surface and the second abutting surface extend from the lead screw 323 to the driving shaft 22, so that the part close to the lead screw 323 is clamped by the tangential gear 321 and the clamping base to achieve axial limiting, and the part is provided with a through hole to be penetrated by the protruding column to achieve circumferential limiting, so as to fix the lifting plate 310.

[0067] In one of the embodiments, the driving mechanism 20 further comprises a driving motor and a driving gear 23, the driving motor is in transmission connection with the driving gear 23, the driving shaft 22 penetrates through the driving gear 23 and is fixed with the driving gear 23; the driving gear 23 comprises a gear body and a lifting part, the lifting part extends along the axial direction of the driving shaft 22 at the end surface of the gear body; the lifting plate 310 is provided with an arc-shaped slot, the arc-shaped slot is used for clamping the lifting part, and the first abutting surface and the second abutting surface are further in abutment with the lifting part to drive the lifting part to lift.

[0068] The driving motor outputs power to the driving gear 23, and the driving gear 23 and the driving shaft 22 are coaxial and relatively fixed. When the driving gear 23 rotates, the driving shaft 22 rotates synchronously.

[0069] The lifting part can be arranged at the lower end surface of the gear body and extend along the axial direction. The part close to the driving shaft 22 of the lifting plate 310 is provided with an arc-shaped slot, the arc-shaped slot has one side opening, the arc-shaped slot is clamped on the lifting part, and then the first abutting surface and the second abutting surface are in abutment with the lifting part.

[0070] For ease of understanding, for example, the tangential motor 33 can drive the tangential gear 321 to rotate, the tangential gear 321 drives the shaft sleeve 322 to rotate synchronously, because the shaft sleeve 322 and the lead screw 323 are in threaded connection, when the shaft sleeve 322 and the tangential gear 321 rotate relatively, the shaft sleeve 322 and the tangential gear 321 will ascend or descend along the axial direction as a whole, drive the clamped lifting plate 310 to ascend or descend synchronously, drive the lifting part by the lifting plate 310, and then drive the driving gear 23, because the driving gear 23 and the driving shaft 22 are fixed, the driving shaft 22 follows the driving gear 23 to ascend or descend, completes the switching between the first preset position and the second preset position, and then realizes the switching of the first transmission group and the second transmission group, changes the output working condition of the cleaning assembly 10.

[0071] In the embodiment, because the tangential gear 321 moves in the axial direction, a worm gear transmission can be arranged between the driving motor and the tangential gear 321, the preset thickness of the worm gear in the axial direction is greater than or equal to the stroke of the tangential gear 321 on the lead screw 323, so that the tangential gear 321 can always maintain transmission when ascending or descending.

[0072] Reference Figure 1 And Figure 2In one of the embodiments, the cleaning assembly 10 is configured to be swingable relative to the driving shaft 22, having a preset swing-out position and a retracted position; the driving shaft 22 drives the cleaning assembly 10 to rotate and swing, and keeps the cleaning assembly 10 in the swing-out position or the retracted position in the tangential direction.

[0073] During the operation of the cleaning device 100, there can be a situation that requires edge cleaning to swing out, or a situation that requires obstacle avoidance, cleaning interruption, or avoidance of part of the surface to be cleaned to retract. In these states, if the cleaning assembly 10 needs to change the rotation direction, the related art cleaning device 100 needs to change the rotation direction of the driving shaft 22, and the change of the rotation direction of the driving shaft 22 will cause the swing of the cleaning assembly 10.

[0074] In this embodiment, the driving shaft 22 drives the cleaning assembly 10 to rotate and swing, and in the tangential direction, the driving shaft 22 is switched between the first transmission group and the second transmission group. Since the first transmission group and the second transmission group are configured to output power in opposite directions, for example, the number of gears of the first transmission group is A, and the number of gears of the second transmission group is A+1, the rotation direction of the cleaning assembly 10 is changed after tangential switching. However, since the swing direction of the cleaning assembly 10 is only controlled by the rotation direction of the driving shaft 22, the cleaning assembly 10 will remain in the swing-out or retracted state without changing the rotation direction of the driving shaft 22. At this time, if the rotation direction of the driving shaft 22 is changed, the rotation direction and the swing direction of the cleaning assembly 10 will be changed simultaneously. If the rotation direction of the driving shaft 22 is changed while being tangential, the swing direction of the cleaning assembly 10 will be changed, but the rotation direction will remain unchanged.

[0075] Therefore, in this embodiment, the tangential mechanism 30 can separately control the output torque direction of the driving shaft 22 to the cleaning assembly 10, so as to realize the combined switching of multiple working states and rapid switching, and provide multiple working modes.

[0076] Moreover, the tangential mechanism 30 is combined with the driving mechanism 20. Compared with the traditional setting of two large motors to separately control the rotation and swing of the cleaning assembly 10, the integration of the cleaning device 100 is improved, and the space occupation is reduced.

[0077] Corresponding to the foregoing application function implementation device embodiments, the present application also provides a cleaning device 100, a cleaning equipment 1000, and corresponding embodiments.

[0078] Referring to Figure 6 The present embodiment also provides a cleaning equipment 1000, which comprises the cleaning device 100 as described above.

[0079] The cleaning equipment 1000 can be a sweeping robot, a mopping robot, a sweeping and mopping integrated robot, a window cleaning robot, etc., which is not limited in the present embodiment.

[0080] The cleaning device 1000 provided by the embodiment is provided with the cleaning device 100, and the cleaning device 100 occupies a smaller space, so that a larger space can be obtained in the body of the cleaning device 1000, which is beneficial to the arrangement and design of the modules of the cleaning device 1000, improves the space utilization of the cleaning device 1000, and is also beneficial to reducing the volume of the cleaning device 1000 and realizing compact design.
