Description

Technical Field

[0001] The present disclosure relates to the technical field of commercial cleaning robots, and in particular to a cleaning mop flipping mechanism with clutch and limit switch functions. Background Art

[0002] A cleaning robot is a robot that can automatically complete cleaning tasks. It can perform various cleaning tasks such as vacuuming, mopping, and window cleaning, reducing people's housework burden. Cleaning robots are usually equipped with sensors and intelligent algorithms, which can autonomously plan cleaning paths, avoid obstacles, and make corresponding adjustments according to environmental changes. Some advanced cleaning robots also have artificial intelligence functions, which can learn and adapt to different home environments and provide more personalized cleaning services. The emergence of cleaning robots has effectively improved the quality of life and work efficiency.

[0003] The mop of the existing cleaning robot on the market is in a ground-hugging state when the robot is working, and is in a lifted state when not working. The lifting height is very limited. In complex environments, such as entering an elevator with a high step, it is inevitable that the mop mechanism will be bumped during work, causing permanent damage to the product. In order to solve the problems of the prior art, a mop flipping mechanism is designed, that is, when it is not working, the mop is flipped above the robot body. In order to further optimize the final effect of this solution, and further considering the possibility that the motor may be stuck due to a complex environment when working, this mechanism also adds a motor flip clutch structure. When the motor is driven to rotate and encounters an external force that jams the motor, the clutch will disengage, causing the two ends of the entire rotating shaft to disengage, ensuring that the motor will not be stuck and damaged due to reverse force applied to the motor. Summary of the invention

[0004] The purpose of the present invention is to provide a cleaning mop flipping mechanism with clutch and limit switch functions to solve the technical problem in the prior art that the mop of a cleaning robot is in a ground-hugging state when the robot is working, and in a lifted state when not working, and the lifting height is very limited. In complex environments, such as entering an elevator with a high step, it is inevitable that the mop mechanism will be hit during operation, causing permanent damage to the product.

[0005] To achieve the above objectives, the present disclosure adopts the following technical solutions:

[0006] The present invention provides a cleaning mop flipping mechanism with clutch and limit switch functions, comprising a main body, a rotating mechanism arranged on the main body, the rotating mechanism being connected to a mop swing arm via a rotating shaft, a mop assembly being arranged at the other end of the mop swing arm, a driving mechanism being arranged on the main body and capable of driving the rotating mechanism to rotate, and a limit switch trigger and a clutch being arranged on the rotating mechanism.

[0007] Optionally, the clutch includes a left end of a gear clutch connected to the main body, one end of the left end of the gear clutch is connected to one end of the right end of the gear clutch, the other end of the right end of the gear clutch is connected to a first spring, the other end of the first spring is connected to a limit switch trigger, and a first spring movably connected to the limit switch trigger is arranged inside the right end of the gear clutch.

[0008] Optionally, the driving mechanism includes a driving motor connected to the main body, and a rotating shaft gear of the driving motor is meshedly connected to the left end of the gear clutch.

[0009] Optionally, one end of the mop swing arm is fixedly connected to a rotating rod that is convenient for connection with a rotating shaft and a limit switch trigger, and the end of the rotating rod is provided with a groove for convenient connection.

[0010] Optionally, a triangular groove for saving materials is provided on the mop swing arm, and the triangular shape of the triangular groove can provide the mop swing arm with better structural stability.

[0011] Optionally, a mop box is provided on the mop assembly to protect the mop assembly.

[0012] Optionally, a more solid mop base is provided at the bottom of the mop assembly.

[0013] Optionally, a connecting socket is provided at one end of the mop swing arm, and an outer wall of the mop assembly is connected to a connecting rod corresponding to the connecting socket and conveniently inserted therein.

[0014] Optionally, the outer wall of the connecting rod is sleeved with a shock-absorbing connecting pad.

[0015] Optionally, a pair of second springs for shock absorption are provided on the mop assembly.

[0016] Optionally, a rectangular connection block is provided on the main body to facilitate the connection and engagement of the device.

[0017] Optionally, a plurality of connecting posts for connecting devices are provided on the main body.

[0018] Optionally, a connection hole for connecting with a screw is provided on the connection column.

[0019] Optionally, a connection card box is provided on the main body to facilitate the connection of the device.

[0020] Optionally, a slot is provided inside the connection card box, and the slot is a groove into which the connection block can be inserted.

[0021] Compared with the prior art, the beneficial effect of the present invention is that when the driving motor receives an electrical signal, the driving shaft rotates, and the shaft drives the entire mop assembly to realize the function of mopping. The up and down flipping of the mop is the stop state position of the entire mechanism controlled by the limit switch. Because the limit switch is a vulnerable component, when the limit switch fails, the entire rotating mechanism does not stop in time when it should stop, and the motor is still rotating, but the structural parts of the entire mechanism have collided, which may cause permanent damage to the motor. To avoid this situation, the clutch structure will be disengaged first when the motor is still running after the limit switch fails, and one end of the motor is separated from the mop assembly. In this way, the motor is equivalent to an unloaded state, ensuring the safety of the motor. The clutch body includes a left end of a gear clutch, a right end of a gear clutch that is directly connected to the motor gear and can be disengaged from the left end of the gear clutch, and a first spring that does not easily disengage the right end of the gear clutch. The mop mechanism has a smooth up and down flipping mechanism, which enables the cleaning robot to be in two states: working and not working, and the motor that controls the mop flipping by the mop position change will not cause permanent damage to the phone in the clutch mechanism when it is stuck.

For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0034] See also Figure 1-3The present invention provides a mop flipping mechanism for cleaning with clutch and limit switch functions, including a main body 1, a connecting card box 21 for convenient device connection is arranged on the main body 1, a slot 22 is arranged inside the connecting card box 21, and the slot 22 is a groove for the connecting block to be inserted, a rectangular connecting block 23 for convenient device connection and connection is arranged on the main body 1, a plurality of connecting columns 18 for connecting between devices are arranged on the main body 1, and a connecting hole 19 connected with a screw is arranged on the connecting column 18, a rotating mechanism 2 is arranged on the main body 1, the rotating mechanism 2 is connected to a mop swing arm 3 through a rotating shaft 6, a mop assembly 4 is arranged at the other end of the mop swing arm 3, a mop box 17 for protecting the mop assembly 4 is arranged on the mop assembly 4, a more solid mop base 25 is arranged at the bottom of the mop assembly 4, a pair of second springs 15 for shock absorption are arranged on the mop assembly 4, a driving mechanism for driving the rotating mechanism 2 to rotate is arranged on the main body 1, and a limit switch trigger 7 and a clutch 8 are arranged on the rotating mechanism 2.

[0035] like Figure 2-3 As shown, one end of the mop swing arm 3 is fixedly connected to the rotating rod 20 that is convenient for connecting with the rotating shaft 6 and the limit switch trigger 7. The ends of the rotating rod 20 are provided with grooves for convenient connection. The mop swing arm 3 is provided with a triangular groove 16 that saves materials. The triangular shape of the triangular groove 16 can make the mop swing arm 3 have better structural stability. The triangle can provide better structural stability in some cases. This is because the three corners of the triangle support each other, making the force transmission more uniform and reducing the risk of structural deformation and collapse. One end of the mop swing arm 3 is provided with a connecting socket 24, and the outer wall of the mop assembly 4 is connected to the connecting rod 13 that corresponds to the connecting socket 24 and is convenient for inserting it. The outer wall of the connecting rod 13 is sleeved with a shock-absorbing connecting pad 14.

[0036] like Figure 1 and Figure 3 As shown, the clutch 8 includes a gear clutch left end 10 connected to the main body 1, one end of the gear clutch left end 10 is connected to one end of the gear clutch right end 11, the other end of the gear clutch right end 11 is connected to a first spring 12, the other end of the first spring 12 is connected to the limit switch trigger 7, and the interior of the gear clutch right end 11 is provided with a first spring 12 movably sleeved with the limit switch trigger 7.

[0037] like Figure 1-2 As shown, the driving mechanism includes a driving motor 5 connected to the main body 1 , and the shaft gear of the driving motor 5 is meshedly connected with the left end 10 of the gear clutch.

[0038] Working principle: when it is necessary to use the cleaning mop flipping mechanism with clutch and limit switch functions, the drive motor 5 first receives an electrical signal to drive the shaft to rotate. Since the shaft gear of the drive motor 5 is meshed with the left end 10 of the gear clutch, the shaft gear of the drive motor 5 drives the entire mop assembly 4 to realize the mop flipping function. The up and down flipping of the mop is the stop state position of the entire mechanism controlled by the limit switch. Because the limit switch is a vulnerable component, when the limit switch fails, the entire rotating mechanism 2 does not stop in time when it should be stopped, and the drive motor 5 is still rotating, but the structural parts of the entire mechanism have collided, which may cause permanent damage to the drive motor 5. To avoid this situation, the clutch 8 will be disengaged first when the limit switch trigger 7 fails and the drive motor 5 is still running, and one end of the motor is separated from the mop assembly 4. In this way, the drive motor 5 is equivalent to an unloaded state, thereby ensuring the safety of the drive motor 5.

[0039] Furthermore, the clutch 8 body includes a gear clutch left end 10, which is directly connected to the motor gear, a gear clutch right end 11 which can be disengaged from the gear clutch left end 10, and a first spring 12 which prevents the gear clutch right end 11 from being easily disengaged.
