Description

Technical Field

[0001] The utility model relates to the technical field of sweeping robots, in particular to a sweeping robot. Background Art

[0002] A sweeping robot is an intelligent household appliance that automatically cleans floors. It integrates modern sensing, artificial intelligence, and automated control technologies, replacing manual cleaning tasks. A sweeping robot typically has a central sweep mechanism on its bottom for cleaning the floor. During operation, the robot repeatedly travels around the room following a pre-set route. The central sweep mechanism's central sweep shaft rotates continuously, driving the roller brush to clean the floor. Foreign matter, such as human, dog, or cat hair or filaments, can often become entangled in the roller brush as it passes over the floor, affecting the proper rotation of the central sweep shaft, ultimately impacting subsequent cleaning efficiency and the cleanliness of the floor. To address this issue, some sweeping robots incorporate a hair-cutting assembly on the central sweep shaft to remove foreign matter from the roller brush. To ensure stable power supply to the cutting assembly, a power supply is often included. However, since the central sweep shaft rotates and the roller brush frequently needs to be disassembled for repair or replacement, connecting a wire to power the cutting assembly is inconvenient and affects the proper operation of the central sweep mechanism.

DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below with reference to the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0032] This embodiment relates to a sweeping robot, referring to Figure 1-Figure 3The invention comprises a bottom housing 100, a middle sweep assembly 200, a power transmission assembly 300, a drive assembly 400, and a cutting assembly 500. The bottom housing 100 houses a control circuit board (not shown). The middle sweep assembly 200 is rotatably mounted on the bottom housing 100 and is detachable for easy cleaning and maintenance. A roller brush 210 is mounted on the outer periphery of the middle sweep assembly 200 for cleaning the floor. The power transmission assembly 300 is mounted on one end of the middle sweep assembly 200 and is electrically connected to the control circuit board. The drive assembly 400 is detachably mounted within the middle sweep assembly 200 and is electrically connected to the power transmission assembly 300. The cutting assembly 500 is detachably mounted within the middle sweep assembly 200 and is connected to the output terminal of the drive assembly 400. The cutting end of the cutting assembly 500 is exposed outside the middle sweep assembly 200 to cut foreign matter from the roller brush 210. During the movement of the sweeping robot, the center sweep assembly 200 rotates, and the outer roller brush 210 of the center sweep assembly 200 also rotates to clean the floor. During the cleaning process, foreign objects on the floor often become entangled in the roller brush 210 of the center sweep assembly 200. Foreign objects such as human or animal hair, filaments, etc. are often entangled in the roller brush 210 of the center sweep assembly 200. The cutting end of the cutting assembly 500 is exposed outside the center sweep assembly 200 to cut foreign objects entangled in the roller brush 210 and prevent them from interfering with the rotation of the center sweep assembly 200. The cutting assembly 500 is directly mounted on the center sweep assembly 200, facilitating timely cleaning. Furthermore, the sweeping robot uses the power transmission assembly 300 to charge and power the drive assembly 400, simplifying the charging process of the drive assembly 400 and avoiding the difficulty of disassembling, replacing, or repairing the center sweep assembly 200 when charging the drive assembly 400. Without the constraints of cables, it also facilitates the replacement or repair of the cutting assembly 500 within the center sweep assembly 200.

[0033] Furthermore, the power transmission component 300 is electrically connected to the control circuit board, and the drive component 400 is electrically connected to the power transmission component 300. The drive component 400 drives the cutting component 500 to cut foreign objects such as hair, which is active cutting. This robot vacuum is also equipped with a sensor (not shown in the drawings) that controls the start and stop of the cutting component 500 via the control circuit board. If the robot vacuum detects that it is operating on a carpet, it will stop cutting foreign objects to ensure that carpets are not accidentally cut. In other embodiments, users can customize the cutting start and stop logic according to different application scenarios.

[0034] In some embodiments, the sweeping robot may also be equipped with a suction device and a dust box connected to the suction device to suck the cut hair and other foreign matter into the dust box, thereby realizing automatic cleaning of hair and other foreign matter.

[0035] Further, refer to Figure 2 and Figure 4-Figure 6The cutting assembly 500 includes a movable blade assembly connected to the output end of the drive assembly 400 and a fixed blade member 530 assembled within the middle sweep assembly 200 and cooperating with the movable blade assembly. Specifically, the cutting area of the movable blade assembly overlaps with the cutting area of the fixed blade member 530. Driven by the drive assembly 400, the movable blade assembly performs horizontal reciprocating motion relative to the fixed blade member 530, cooperating with the fixed blade member 530 to shear foreign matter from the roller brush 210.

[0036] Specifically, refer to Figure 2 and Figure 4-Figure 6 The movable blade assembly includes a movable blade pressure member 510 connected to the output end of the drive assembly 400 on one side, and a movable blade member 520 detachably mounted on the movable blade pressure member 510. Driven by the drive assembly 400, the movable blade pressure member 510 moves, thereby driving the movable blade member 520 to perform horizontal reciprocating motion relative to the fixed blade member 530 to cut foreign matter from the roller brush 210.

[0037] Further, refer to Figure 5-Figure 7 The movable blade pressure member 510 has a latching post 512 on its side facing the movable blade member 520, extending toward the movable blade member 520. The movable blade member 520 has a latching hole 521 that engages with the latching post 512. The latching post 512 passes through the latching hole 521 and is exposed on the side of the movable blade member 520 facing the fixed blade member 530. The latching connection between the latching post 512 and the latching hole 521 facilitates user replacement of the movable blade pressure member 510 or the movable blade member 520, as well as assembly. Furthermore, the fixed blade member 530 is provided with a clearance hole 531 for circumventing the clamping post 512. The clamping post 512 extends through the clamping hole 521 and is exposed on the side of the movable blade member 520 facing the fixed blade member 530. When the driving assembly 400 drives the movable blade pressing member 510 to move, thereby driving the movable blade member 520 to perform horizontal reciprocating motion, the clearance hole 531 in the fixed blade member 530 clears the clamping post 512, thereby preventing the horizontal reciprocating motion of the movable blade member 520 from being affected. In addition, since the fixed blade member 530 is fixed to the middle sweep assembly 200 via fasteners such as screws, a travel hole for the fastener to clear the fastener is provided in the movable blade assembly to prevent the fastener from restricting the horizontal reciprocating motion of the movable blade assembly.

[0038] In this embodiment, referring to Figure 5-Figure 7The cutting assembly 500 further includes a pressing piece spring 540 that passes through the movable blade 520 and is engaged at one end with the side of the movable blade pressing piece 510 facing away from the movable blade 520, and at the other end with the side of the fixed blade 530 facing away from the movable blade 520. The pressing piece spring 540 is used to press the movable blade 520 against the fixed blade 530. The pressing piece spring 540 locks the movable blade pressing piece 510 and the fixed blade 530 together, clamping the movable blade 520 therebetween, ensuring that the movable blade 520 is tightly attached to the fixed blade 530 to cut foreign matter from the roller brush 210. Specifically, the pressure piece spring piece 540 is clamped on the side of the movable knife pressure piece 510 facing away from the movable knife piece 520, and is provided with an abutment column 541 extending obliquely to both sides, and a buckle 542 is provided at the other end; the movable knife pressure piece 510 is provided with a first groove 511 corresponding to the abutment column 541, the movable knife piece 520 is provided with a first mounting hole 522 for the pressure piece spring piece 540 to pass through, and the fixed knife piece 530 is provided with a second mounting hole 532 for the pressure piece spring piece 540 to pass through, and the second mounting hole 532 is provided on the fixed knife piece 530. A second groove 5321 is defined within the mounting hole 532. A pressure piece spring 540 is disposed within the first mounting hole 522. A contact post 541 extends through the first groove 511 and abuts against the side of the movable blade pressure piece 510 facing away from the movable blade 520. A latch 542 extends through the second mounting hole 532 and engages with the second groove 5321. The contact post 541 and latch 542 cooperate to lock the movable blade 520 between the movable blade fixed piece and the fixed blade 530, ensuring the locking effect of the pressure piece spring 540. The pressure piece spring 540 is elastic and does not affect the sliding of the movable blade assembly. In some embodiments, the pressure piece spring 540 can also be another locking member.

[0039] In this embodiment, referring to Figure 6-Figure 7The driving assembly 400 includes: a driving device 410 electrically connected to the power transmission assembly 300, an eccentric wheel 420 fixedly mounted on the output shaft of the driving device 410, and a ball 430; one end of the ball 430 is rollingly connected to the eccentric wheel 420, and the other end is rollingly connected to the side of the movable blade pressure piece 510 facing the driving assembly 400. Specifically, a limiting portion 513 is provided on the side of the movable knife pressure piece 510 facing the output shaft of the driving device 410, and the limiting portion 513 is provided with a limiting groove 5131 for the ball 430 to be placed, and an arc-shaped rolling groove 421 is provided on the peripheral side of the eccentric wheel 420 for the ball 430 to roll; the arc-shaped rolling groove 421 extends away from the output shaft of the driving device 410 around the central axis of the eccentric shaft, and the arc-shaped rolling groove 421, the ball 430 and the limiting groove 5131 cooperate to convert the circular motion of the ball 430 and the eccentric wheel 420 into a horizontal reciprocating motion of the movable knife pressure piece 510 relative to the fixed knife piece 530, thereby driving the movable knife piece 520 to perform horizontal reciprocating motion relative to the fixed knife piece 530, so that the movable knife piece 520 and the fixed knife piece 530 cooperate to complete the cutting work. The specific process is: turn on the driving device 410, the output shaft of the driving device 410 rotates, and then drives the eccentric wheel 420 to rotate, the ball 430 rolls along the arc groove 421 on the eccentric wheel 420, and then the ball 430 drives the movable knife pressure piece 510 to perform horizontal reciprocating motion, and finally drives the movable knife piece 520 to perform horizontal reciprocating motion relative to the fixed knife piece 530.

[0040] Further, refer to Figure 3 The middle sweep assembly 200 includes a first housing 220 rotatably mounted on the bottom housing 100 via a rotating shaft, and a second housing 230 detachably mounted on the first housing 220, facilitating replacement of the cutting assembly 500 within the middle sweep assembly 200. The first housing 220 and the second housing 230 each define mounting slots for the drive assembly 400. A roller brush 210 is disposed on the outer periphery of the first and second housings 220, 230, for cleaning the floor.

[0041] Specifically, the first shell 220 and the second shell 230 are respectively provided with outwardly extending comb teeth 240 corresponding to the exposed cutting end of the cutting component 500. The comb teeth 240 are used to locate and comb foreign matter such as hair, thereby facilitating cutting by the cutting component 500. At the same time, the comb teeth 240 can also protect the cutting component 500 and prevent damage to the cutting component 500 due to accidental contact with hard objects or impurities during the cutting process.

[0042] In this embodiment, referring to Figure 3The power transmission component 300 includes a first coil 310 electrically connected to the control circuit board and housing a wireless charging transmitter, and a second coil 320 housing a wireless charging receiver electrically connected to the wireless charging transmitter. The second coil 320 is electrically connected to the drive device 410. Specifically, the first coil 310 is mounted on the rotating shaft of the first housing 220, while the second coil 320 is mounted on the rotating shaft of the first housing 220 and positioned between the first coil 310 and the rotating shaft. The first coil 310 is electrically connected to the control circuit board, wirelessly transmitting power between the first coil 310 and the second coil 320, while the second coil 320 is electrically connected to the drive device 410. This simplifies the charging process of the drive component 400, eliminates cable restrictions, and facilitates subsequent replacement of the mid-sweep component 200.

[0043] The sweeping robot also includes: a middle sweep gear box assembly for driving the middle sweep assembly 200 to rotate. The middle sweep gear box assembly is electrically connected to the control circuit board. One end of the middle sweep gear box assembly is for the rotating shaft on the first shell 220 to be placed.
