[0042] To solve the above problems, the embodiment of the present application provides a transmission mechanism which can optimize the control mode, improve the compatibility, and be beneficial to the function expansion of the cleaning equipment.

[0043] The technical solutions of the embodiment of the present application are described in detail below with reference to the drawings.

[0044] Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The embodiment provides a transmission mechanism 10 applied to a cleaning equipment, the transmission mechanism 10 comprises a driving member 11, a clutch member 12, a first transmission group 13 and a second transmission group 14; the driving member 11 is used for transmission connection with a driving motor, and is configured to be movable along a first preset direction; the clutch member 12 is arranged on the driving member 11, and is provided with a clutch part 121; the first transmission group 13 comprises a first transmission member 131, and the first transmission member 131 is provided with a first matching part 1311 matched with the clutch part 121; the second transmission group 14 comprises a second transmission member 141, and the second transmission member 141 is provided with a second matching part 1411 matched with the clutch part 121; the first transmission group 13 and the second transmission group 14 are respectively used for outputting power, and are configured to have opposite output directions; wherein the first transmission member 131, the clutch member 12 and the second transmission member 141 are sequentially arranged on the driving member 11 along the first preset direction, and the first transmission member 131 and the second transmission member 141 are fixed in the first preset direction.

[0045] The first transmission group 13 and the second transmission group 14 can be used for connecting a cleaning assembly 21, and are used for driving the cleaning assembly 21 to move.

[0046] The embodiment sets that the first transmission member 131 and the second transmission member 141 are fixed in the first preset direction, when the clutch member 12 moves along with the driving member 11 in the first preset direction, the clutch member 12 can be engaged with the first transmission member 131 or the second transmission member 141 and realize transmission. Since the output directions of the first transmission group 13 and the second transmission group 14 are opposite, the power output direction of the transmission mechanism 10 can be controlled through the movement of the clutch member 12, so that the same direction power output can be realized when the driving motor rotates forward and reversely, the control scheme is increased, the control mode is optimized, the compatibility can be improved, and the function expansion of the cleaning equipment is beneficial.

[0047] For the convenience of description, it is assumed that the first transmission group 13 does not change the direction of power input when outputting power, and the second transmission group 14 is opposite to the first transmission group 13. For example, when the driving member 11 rotates forward with the driving motor, if the control clutch 12 is combined with the first transmission member 131, the control clutch 12 drives the first transmission member 131 to rotate, so that the first transmission group 13 outputs power in the same direction, i.e. forward power; if the control clutch 12 is combined with the second transmission member 141, the control clutch 12 drives the second transmission member 141 to rotate, so that the second transmission group 14 outputs power in the opposite direction, i.e. reverse power. By using the same principle, when the driving motor reverses, the first transmission group 13 will output reverse power, and the second transmission group 14 will output forward power.

[0048] Therefore, the transmission mechanism 10 of the embodiment can output forward or reverse power when the driving member 11 rotates forward, and can also output forward or reverse power when the driving member 11 reverses, so that the ascending and descending of the cleaning assembly 21 can be controlled when the driving motor rotates forward or reverses.

[0049] In the prior art, the forward rotation of the driving motor is generally used to control the transmission mechanism 10 to output forward power, and the reverse rotation of the driving motor is used to control the transmission mechanism 10 to output reverse power. For example, the forward power can be used to control the cleaning assembly 21 to descend, and the reverse power can be used to control the cleaning assembly 21 to ascend. However, when the driving motor is connected to multiple mechanisms, if another mechanism needs the driving motor to rotate forward, the cleaning assembly 21 can only be driven to descend by the forward power and cannot be adjusted according to actual needs. However, the transmission mechanism 10 of the embodiment can adjust the direction of the output power according to needs, and can control the cleaning assembly 21 to ascend or descend when the driving motor rotates forward or reverses.

[0050] Referring to Figure 3 and Figure 4 In one embodiment, the driving member 11 includes a rotating shaft, and the control clutch 12 is provided with a through hole 120 in the first preset direction; the rotating shaft is arranged in the through hole 120 and fixedly connected with the control clutch 12.

[0051] In the embodiment, the rotating shaft is arranged to be movable in the first preset direction and rotatable in the second preset direction. The first preset direction can be in the axial direction Y, such as ascending or descending, and the second preset direction can be in the circumferential direction R, such as clockwise rotation or counterclockwise rotation.

[0052] Since the rotating shaft passes through the through hole 120 and is fixedly connected to the clutch 12, when the rotating shaft rotates in the circumferential direction R and moves in the axial direction Y, the clutch 12 rotates and moves synchronously with the rotating shaft, and the rotation direction and movement direction are the same. When the clutch 12 engages with the first transmission member 131 or the second transmission member 141, it can drive the first transmission member 131 or the second transmission member 141 to rotate synchronously.

[0053] See Figure 3 and Figure 5 In one embodiment, the first transmission member 131 and the second transmission member 141 are respectively provided with through holes 1310 and 1410 (not shown in the figure) along a first preset direction; the driving member 11 is sequentially inserted through the through holes 1310 and 1410, and is slidably connected to the first transmission member 131 and the second transmission member 141 respectively.

[0054] The rotating shaft is configured to move along a first preset direction and rotate along a second preset direction. The first preset direction can be axial movement along the Y axis, such as rising or falling, and the second preset direction can be circumferential rotation along the R axis, such as clockwise or counterclockwise rotation.

[0055] The driving member 11 is slidably connected to the first transmission member 131 and the second transmission member 141 in both the axial direction Y and the circumferential direction R. Thus, the driving member 11 can rotate and move relative to the first transmission member 131 and the second transmission member 141. Since the driving member 11 is fixedly connected to the clutch member 12, when the clutch member 12 moves with the driving member 11 in the axial direction Y to a position close to the first transmission member 131 or the second transmission member 141 and engages, it can drive the first transmission member 131 or the second transmission member 141 to rotate synchronously, thereby connecting and transmitting with the first transmission group 13 or the second transmission group 14.

[0056] See Figure 4 and Figure 5 In one embodiment, the clutch 12 is provided with clutch portions 121 on both sides in a first preset direction; the first transmission member 131 and the second transmission member 141 are respectively provided with a first mating portion 1311 and a second mating portion 1411 on the side facing the clutch 12.

[0057] The clutch 12 is engaged with the first mating part 1311 on one side of the first preset direction by the clutch part 12, and the clutch 12 is engaged with the second mating part 1411 on the other side of the first preset direction, thereby driving the first transmission member 131 or the second transmission member 141 to rotate.

[0058] For example, the first preset direction is upward, the upper end face and the lower end face of the clutch part 12 are respectively provided with a clutch part 121, the first transmission part 131 can be arranged on the upper side of the clutch part 12, the lower end face of the first transmission part 131 is provided with a first matching part 1311, and the second transmission part 141 can be arranged on the lower side of the clutch part 12, the upper end face of the second transmission part 141 is provided with a second matching part 1411, so as to realize the matching with the first transmission part 131 when the clutch part 12 moves upward and the matching with the second transmission part 141 when the clutch part 12 moves downward.

[0059] Referring to Figures 3 to 5 In one embodiment, the clutch part 121 is provided with a clamping protrusion, and the first matching part 1311 and the second matching part 1411 are respectively provided with a clamping recess; and / or, the clutch part 121 is provided with a clamping recess, and the first matching part 1311 and the second matching part 1411 are respectively provided with a clamping protrusion.

[0060] The clutch part 121 can be provided with a clamping protrusion, the clamping protrusion can protrude from the end face of the clutch part 12 towards the first transmission part 131 and the second transmission part 141, and can be a boss, a ball or other protruding structures, which are not limited in the embodiment; the first transmission part 131 and the second transmission part 141 can be provided with a clamping recess corresponding to the clamping protrusion, when the clutch part 12 matches with the first transmission part 131 or the second transmission part 141, the clamping protrusion is embedded in the clamping recess, so as to realize clamping, and the clutch part 12 can drive the first transmission part 131 or the second transmission part 141 to move.

[0061] It can be understood that the clutch part 121 can also be provided with a clamping recess, the clamping recess can be recessed from the end face of the clutch part 12 towards the first transmission part 131 and the second transmission part 141, and the first transmission part 131 and the second transmission part 141 can be provided with a clamping protrusion corresponding to the clamping recess, so as to realize clamping.

[0062] The number of the clamping protrusion and the clamping recess is not limited in the embodiment.

[0063] Referring to Figures 3 to 5 In one embodiment, the clutch part 121, the first matching part 1311 and the second matching part 1411 are all provided with a sawtooth structure, the sawtooth structure includes a clamping protrusion and a clamping recess, when the sawtooth structure of the clutch part 121 matches with the sawtooth structure of the first matching part 1311 or the second matching part 1411, the clamping protrusion arranged on the clutch part 121 is embedded in the clamping recess of the first matching part 1311 or the second matching part 1411, and the clamping protrusion arranged on the first matching part 1311 or the second matching part 1411 is embedded in the clamping recess of the clutch part 121, so that the sawtooth structures are engaged, thereby enhancing the reliability of the fixed connection and improving the transmission effect.

[0064] Participate Figure 1 and Figure 2In one embodiment, the first transmission group 13 and the second transmission group 14 are respectively used to connect with the cleaning assembly 21 to control the lifting movement of the cleaning assembly 21.

[0065] The first transmission group 13 and the second transmission group 14 respectively obtain the driving force of the driving motor to control the lifting movement of the cleaning assembly 21. For example, when the driving motor rotates forward, the first transmission group 13 can output forward power to control the cleaning assembly 21 to descend, and the second transmission group 14 can output reverse power to control the cleaning assembly 21 to ascend; when the driving motor reverses, the first transmission group 13 can output reverse power to control the cleaning assembly 21 to ascend, and the second transmission group 14 can output forward power to control the cleaning assembly 21 to descend.

[0066] The transmission mechanism 10 of the embodiment can control the lifting movement of the cleaning assembly 21 respectively through the clutch 12 and the first transmission group 13 or the second transmission group 14.

[0067] Referring to Figure 1 and Figure 2 To realize that the power output directions of the first transmission group 13 and the second transmission group 14 are opposite, in one embodiment, the first transmission group 13 includes a first gear group, and the second transmission group 14 includes a second gear group; the number of gears of the first gear group is n, the number of gears of the second gear group is B=n+1, and n is a positive integer greater than or equal to 1.

[0068] The first gear group and the second gear group can be gear groups with parallel axes. When the axes of the gears in the gear group are parallel to each other, if the number of external meshing pairs of the gears is even, the rotation directions of the first gear and the last gear are opposite; if the number of external meshing pairs of the gears is odd, the rotation directions of the first gear and the last gear are the same.

[0069] The first transmission member 131 can be the first gear of the first transmission group 13, and the second transmission member 141 can be the first gear of the second transmission group 14.

[0070] The cleaning assembly 21 can be provided with a cleaning rotating gear 210 for transmission connection with the first transmission group and the second transmission group, respectively. The cleaning rotating gear 210 is coaxially fixed with the cleaning member to drive the cleaning member to rotate.

[0071] When n = 1, the gear number A of the first gear set = 1, only the first gear is arranged, the first gear is combined with the clutch 12, and the rotating direction of the clutch 12 is opposite, the cleaning rotating gear 210 is engaged with the first gear of the first gear set, and a gear set with two gears is formed. Since the rotating direction of the cleaning rotating gear 210 and the first gear of the first gear set is opposite, the rotating direction of the clutch 12 is the same, and the rotating direction of the driving member 11 is also the same. The gear number B of the second gear set = 2, and the first gear and the last gear are engaged. When the first gear is combined with the clutch 12 and is transmitted to the engaged last gear, the rotating direction of the first gear is opposite to that of the clutch 12, the rotating direction of the last gear is opposite to that of the first gear, and the rotating direction of the driving member 11 is the same. Therefore, the cleaning rotating gear 210 engaged with the last gear is opposite to the last gear, and the rotating direction of the driving member 11 is opposite. It can be understood that when n = 2, A = 2, and B = 3. The rotating direction of the power output by the first gear set is opposite to that of the driving member 11, and the rotating direction of the power output by the second gear set is the same as that of the driving member 11.

[0072] The number of the first gear set and the second gear set is arranged in the embodiment, so that the rotating directions of the power output by the two gear sets are controlled, and the ascending and descending of the cleaning assembly 21 can be controlled when the driving member 11 rotates forward or reversely.

[0073] Corresponding to the foregoing application function implementation device embodiment, the application further provides a cleaning device, a cleaning equipment and corresponding embodiments.

[0074] Figure 6 is a system structure schematic block diagram of the cleaning device shown in the embodiment of the application.

[0075] Referring to Figure 6 The embodiment provides a cleaning device 20, which comprises the transmission mechanism 10 as described above.

[0076] The cleaning device 20 can further comprise a cleaning assembly 21 and a driving motor 22. The driving motor 22 is in transmission connection with the driving member 11. The cleaning assembly 21 is connected with the first transmission set 13 and the second transmission set 14 respectively. When the driving motor 22 transmits power to the driving member 11, the driving member 11 drives the clutch 12 to move. The clutch 12 is combined with the first transmission member 131 or the second transmission member 141, so as to drive the first transmission set 13 or the second transmission set 14 to move, and then output power to the cleaning assembly 21. Since the rotating directions of the power output by the first transmission set 13 and the second transmission set 14 are different, the rotating direction of the power output can be controlled, so as to control the ascending and descending of the cleaning assembly 21.
