[0002] A cleaning robot is a type of smart household cleaning appliance that can automatically sweep, vacuum, and mop the floor. Depending on the functions of the application, there are vacuum robots, mopping robots, and robots that can mop and vacuum all in one. With the advancement of science and technology and the improvement of people's quality of life, cleaning robots have entered the lives of more and more people.

[0003] The existing tray-type mopping cleaning robot mops the surface to be cleaned by rotating the mop tray during the sweeping and vacuuming process. If you want to mop a larger area, you need to extend the tray cloth from the robot. The tray cloth will inevitably collide with obstacles during cleaning, and when the robot is in motion, the tray cloth will cause the cleaning mechanism to reverse excessively, causing damage to the swing drive mechanism that drives the cleaning mechanism to swing, affecting its use. In this case, the general practice is to install a torsion spring or other buffer structure at the connection between the cleaning mechanism and the swing drive mechanism, but this structure can only cope with a small range of reversal and cannot adapt to a larger angle of reversal. Summary of the invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a cleaning module with a clutch function, which can cope with a larger angle of reversal than a torsion spring or other replacement structure, thereby improving the applicability of the cleaning robot.

[0008] When the external force received by the second gear is greater than the matching force between the first clutch component and the second clutch component, the first clutch component and the second clutch component are disengaged to realize the second gear to rotate relative to the first gear.

[0015] Beneficial effects of the utility model:

[0016] The utility model discloses a cleaning module with a clutch function, by arranging a first clutch component and a second clutch component in a swing transmission assembly connected between a swing driving mechanism and a cleaning mechanism.

[0028] A cleaning robot is a type of smart household cleaning appliance that can automatically sweep, vacuum, and mop the floor. Depending on the functions of the application, there are vacuum robots, mopping robots, and robots that can mop and vacuum all in one. With the advancement of science and technology and the improvement of people's quality of life, cleaning robots have entered the lives of more and more people.

[0029] The existing tray-type mopping cleaning robot mops the surface to be cleaned by rotating the mop tray during the sweeping and vacuuming process. If you want to mop a larger area, you need to extend the tray cloth from the robot. The tray cloth will inevitably collide with obstacles during cleaning, and when the robot is in motion, the tray cloth will cause the cleaning mechanism to reverse excessively, causing damage to the swing drive mechanism that drives the cleaning mechanism to swing, affecting its use. In this case, the general practice is to install a torsion spring or other buffer structure at the connection between the cleaning mechanism and the swing drive mechanism, but this structure can only cope with a small range of reversal and cannot adapt to a larger angle of reversal.

[0030] In order to solve the above problems, this embodiment discloses a cleaning module with a clutch function, and its structure is as follows: Figures 1 to 4 As shown, the cleaning module includes a swing driving mechanism 100 and a cleaning mechanism 107, wherein the swing driving mechanism 100 is used to drive the cleaning mechanism 107 to swing;

[0031] The swing drive mechanism 100 includes a swing housing 101, a swing drive member 102 mounted on the swing housing 101, and a swing transmission assembly 103. The swing transmission assembly 103 includes a first gear 104, a second gear 105, a first clutch member 200 coaxially rotating with the first gear 104, and a second clutch member 204 coaxially rotating with the second gear 105. The first gear 104 is drivingly connected to the swing drive mechanism 100, and the second gear 105 is drivingly connected to the cleaning mechanism 107. The first clutch member 200 cooperates with the second clutch member 204 to realize the coaxial rotation of the first gear 104 and the second gear 105.

[0032] When the external force received by the second gear 105 is greater than the matching force between the first clutch 200 and the second clutch 204 , the first clutch 200 and the second clutch 204 are disengaged to enable the second gear 105 to rotate relative to the first gear 104 .

[0033] It should be noted that the swing driving member 102 in this embodiment is preferably a stepping motor, the swing transmission assembly 103 further includes a third gear 106, a rack 108 is provided on the side of the cleaning mechanism 107 away from its cleaning end, and the second gear 105, the third gear 106 and the rack 108 are meshed in sequence. The working principle of how the swing driving member 102 drives the first gear 104, the second gear 105, and the third gear 106 to swing the cleaning mechanism 107 belongs to the prior art and will not be repeated here.

[0034] Specifically, the present embodiment provides a cleaning module with a clutch function, in which a first clutch 200 and a second clutch 204 are arranged in a swing transmission assembly 103 connected between a swing drive mechanism 100 and a cleaning mechanism 107. Under normal circumstances, the first clutch 200 and the second clutch 204 cooperate to realize the transmission of the first gear 104 and the second gear 105, thereby ensuring the normal connection between the swing drive mechanism 100 and the cleaning mechanism 107; if the tray cloth collides with an obstacle and the external force received is greater than the cooperation force between the first clutch 200 and the second clutch 204, the first clutch 200 and the second clutch 204 will be disengaged so that the second gear 105 rotates relative to the first gear 104, thereby avoiding damage caused by excessive reversal of components such as the swing drive member 102 and the swing transmission assembly 103, and effectively improving the service life and applicability of the cleaning robot.

[0035] Furthermore, the first clutch member 200 includes a first body 201 coaxially rotating with the first gear 104, and a blind hole 202 is provided on one end face of the first body 201 away from the first gear 104, and the inner side wall of the blind hole 202 extends outward and is equidistantly provided with a plurality of arc surfaces 203; the second clutch member 204 includes a second body 205 coaxially rotating with the second gear 105, and a protrusion 206 adapted to the arc surface 203 is provided on one side of the second body 205. Figure 3 and Figure 4 It can be seen that the protrusion 206 sinks into the arc surface 203 to realize the cooperation between the first clutch member 200 and the second clutch member 204; when the external force is greater than the friction between the protrusion 206 and the arc surface 203, the protrusion 206 is deformed and disengaged from the above-mentioned arc surface 203, and sinks into the adjacent arc surface 203, completing the clutch of the swing transmission assembly 103.

[0036] Preferably, there are two protrusions 206, which are symmetrically arranged about the second body 205. In addition, the second body 205 and the protrusions 206 are integrally formed, and the second body 205 is an elastic structure, preferably a silicone structure, so as to ensure the stability of the first clutch 200 and the second clutch 204 when they are engaged.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
