Referring to fig. 1 to 4, a manual-automatic cleaning mechanism includes a rotatable cleaning assembly 1, a driving assembly 2 in power transmission connection with the cleaning assembly 1, and a traveling wheel assembly 3, wherein a transmission shaft 11 is disposed at an end of the cleaning assembly 1. The transmission shaft 11 is connected with a clutch component 4. Drive assembly 2 passes through motor and gear reduction box and constitutes, and drive assembly includes the driving gear, and the output gear meshing of driving gear and motor, the middle part of driving gear are connected with the pinion through the bearing, and the pinion meshing is connected on the drive belt, the opposite side meshing back second gear of drive belt. The structure of the gear reduction box is not limited to the structure shown in the drawings, and other gear reduction boxes may be employed. The cleaning assembly 1 comprises a cleaning brush main body, and transmission shafts 11 are arranged at two ends of the cleaning brush main body. The walking wheel assembly 3 comprises two symmetrical walking wheels which are connected with a transmission shaft 11 through a clutch component 4.

The clutch member 4 includes a first gear 41 in driving connection with the drive assembly 2 and a second gear in driving connection with the road wheel assembly 3. A plurality of clutch teeth 43 protruding inwards are uniformly arranged in the first gear 41 and the second gear 42 along the circumferential direction at intervals. A clutch plate 12 is arranged in the transmission shaft 11, a sliding groove 13 is arranged on the transmission shaft 11, and the clutch plate 12 is movably arranged in the sliding groove 13. The transmission shaft 11 is arranged at a distance from the first gear 41 and the second gear 42. There is a gap between the transmission shaft 11 and the first gear 41 and the second gear 42, and this gap is used as a movement space of the clutch plate 12 in the first gear 41 and the second gear 42, so that the clutch plate 12 slides in the sliding groove 13 when pushed by the clutch teeth 43, and when the clutch plate 12 is pushed to the limit position, there is at least a certain gap between the clutch plate 12 and the first gear 41 and the second gear 42, and mutual interference friction between the two is avoided. The second gear 42 is engaged with a gear in the road wheel assembly 3, and the outer side of the second gear 42 is rotatably connected to a bearing. The first gear 41 meshes with the output of the gear reduction box.

The clutch plate 12 is movably disposed in the transmission shaft 11, and the rotation of the first gear 41 or the second gear 42 rotates the clutch teeth 43 and pushes the clutch plate 12, so that the clutch plate 12 drives the transmission shaft 11 to rotate. The clutch teeth 43 are provided with a pushing surface A and a pushing surface B, the clutch plate 12 is provided with a pushing surface C and a pushing surface D, the pushing surface A is in contact with the pushing surface C to enable the clutch teeth 43 to push the clutch plate 12 to rotate, and the pushing surface B is in contact with the pushing surface D to enable the clutch teeth 43 to push the clutch plate 12 to move in the transmission shaft 11. The pushing surface B contacts with the pushing surface D so as to push the clutch plate 12 to slide in the sliding groove 13 in a reciprocating manner. The outermost end positions of the pushing surfaces B and D are contacted to push the clutch plate 12 to the straight outermost side. The pushing surface A and the pushing surface C are plane pushing surfaces, the pushing surface B is an arc pushing surface, and the pushing surface D is an inclined pushing surface. The power transmission to the transmission shaft 11 is realized by the cooperation of the clutch plate 12 and the clutch teeth 43. The number of the clutch teeth 43 is 3, and the clutch plate 12 is in a central symmetrical structure.

Referring to fig. 5 and 6, when the first gear 41 rotates counterclockwise relative to the transmission shaft 11, the pushing surface a rotates to be close to the pushing surface C, and after the pushing surface a and the pushing surface C contact each other, since both pushing surfaces are plane pushing surfaces and are adhered together, the pushing surface C is pushed to start to rotate synchronously, at this time, the clutch plate 12 cannot slide in the sliding groove 13, the transmission shaft 11 is driven to rotate synchronously by the clutch plate 12, and the cleaning assembly 1 starts to rotate. In this case, as the transmission shaft 11 starts to rotate, the other clutch plate 12 on the transmission shaft 11 also starts to rotate relative to the second gear 42, and the rotation direction of the clutch plate 12 is counterclockwise. Then, when the clutch plate 12 rotates, the pushing surface D of the clutch plate will approach the pushing surface B, and since the arc pushing surface B and the pushing surface D of the inclined surface will not be clamped, the pushing surface D is pushed under the action of the pushing surface B, so that the clutch plate 12 is pushed along the sliding groove 13, and the two ends of the clutch plate 12 and all the clutch teeth 43 of the second gear repeat the above-mentioned movement. During the rotation, the pushing surface D of the clutch plate 12 is always in contact with the pushing surface B, so that the power of the driving assembly 2 is not transmitted to the road wheel through the transmission shaft 11 and the clutch plate 12. In this case, power transmission is performed between one clutch plate 12 and the gear, and power transmission is not performed between the other clutch plate 12 and the other gear, and only the clutch plate slides back and forth in the sliding groove 13. On the contrary, the counterclockwise rotation of the second gear 42 can be obtained (the section of the connection part of the second gear 42 and the transmission shaft 11 is the same as that in fig. 5). That is, when any clutch plate 12 receives power transmission, the other clutch plate 12 is in repeated sliding motion and does not transmit any power.

Therefore, the transmission shaft 11 passes through the first gear 41 into the second gear 42 so that the clutch plate 12 is correspondingly positioned in the first gear 41 and the second gear 42, and the transmission shaft 11 is in power transmission connection with the first gear 41 or the second gear 42 through the clutch plate 12 so as to selectively enter the electric sweeping mode and the manual sweeping mode.

When the leaf sweeping machine is in an electric sweeping mode, the driving assembly 2 is started and drives the first gear 41 to rotate, the first gear 41 pushes the pushing surface C of the clutch plate 12 through the pushing surface a to enable the transmission shaft 11 to drive the sweeping assembly 1 to rotate, and the pushing surface B of the other clutch plate 12 is in contact with the pushing surface D to enable the other clutch plate to slide in the second gear 42. The travelling wheels can be pushed, and the rotation speed of the second gear 42 is smaller than that of the first gear 41 due to the slow rotation speed of the travelling wheels during pushing, so that the second gear 42 is considered to be stationary relative to the first gear 41 in this case. The second gear 42 rotates anticlockwise and cannot cause the push surface A of the clutch tooth 43 on the second gear 42 to be in contact with the push surface C of the clutch plate 12, only the first gear 41 provides power for the transmission shaft 11, the walking wheel assembly 3 can normally (anticlockwise rotate) move forward under the condition that the cleaning assembly 1 rotates freely, the leaf sweeping machine can move forward, and at the moment, electric leaf sweeping is achieved.

When the leaf sweeping machine is in a manual sweeping mode, the driving assembly 2 is closed, the traveling wheel assembly 3 rotates, the second gear 42 pushes the pushing surface C of the clutch plate 12 through the pushing surface A to enable the transmission shaft 1411 to drive the sweeping assembly 1 to rotate, and the pushing surface B of the other clutch plate 12 is in contact with the pushing surface D to enable the other clutch plate to slide in the first gear 41, which is in the manual sweeping mode. The first gear 41 is at a standstill, the clutch plate 12 on the transmission shaft 11 rotates counterclockwise relative to the first gear 41, and the clutch plate 12 slides back and forth in the sliding groove 13 due to the pushing surface B. Therefore, the leaf machine is swept in the promotion and is advanced, and walking wheel subassembly 3 drives when advancing and cleans subassembly 1 rotation, cleans 1 rotational speed of group this moment and decides by walking speed, and the rotation of walking wheel can not be with power transmission to drive assembly 2 again simultaneously, realizes manually sweeping the leaf.

Under electric cleaning mode and manual cleaning mode, transmission shaft 11 obtains only power input, because the existence of clutch disc 12, can not interfere each other between this power input, decide the rotational speed that cleans subassembly 1 by drive assembly under the electric mode, walking wheel assembly 3 is static or motion all can not influence this moment, clean subassembly 1 is in under the rotational speed state than ideal always this moment, make the operator avoid walking fast always, clean the effect and be in the optimum state always, drive the brush after slowing down through the gear box, can make the brush obtain great transmission moment of torsion, play better cleaning effect. Under the condition that no power supply exists (manual mode), the walking wheel assembly 3 is pushed to rotate, and the cleaning assembly 1 can synchronously rotate, so that the cleaning function is realized, and the manual-automatic integrated cleaning is realized.

The gear reduction box can also be reasonably replaced by the existing conventional speed reduction parts such as a planetary gear reduction box or a belt speed reduction. A lithium battery is selected as a power supply to supply power for the motor. Meanwhile, a gear reduction box can be omitted, and a low-speed large-torque motor is selected to directly drive the transmission shaft, so that an electric driving mode is realized.

FIG. 7 is a perspective view of the leaf sweeper, wherein the sweeping assembly is located within a sweeper head of the leaf sweeper, the traveling wheel assembly is located below the sweeper head, and the motor and gear reduction box are located within a housing of the leaf sweeper.
