Description

Technical Field

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

[0002] A sweeping robot, also known as an automatic sweeper, smart vacuum cleaner, or cleaning robot, is a type of smart home appliance that can clean the floor within a specific area. During operation, a sweeping robot typically uses the rotation of its brush to lift foreign objects from the ground in the area it passes through. This foreign matter is then sucked up by a suction component and deposited in a dirt storage chamber, thereby completing the cleaning process. During the cleaning process, foreign matter inevitably becomes entangled in the brush. This foreign matter typically consists of human or animal hair, flocs, or filaments. Over time, this accumulation not only affects the proper rotation of the brush, thus affecting subsequent cleaning efficiency and the cleanliness of the floor after cleaning, but also easily harbors dirt and grime. To promptly remove foreign matter entangled in the brush, two methods are currently used: adding a trimming assembly to the brush and manually removing it. The former presents a risk of cuts when replacing the brush, while the latter offers low cleaning efficiency and compromises user experience, thus urgently requiring improvement.

DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] 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.

[0031] This embodiment relates to a cleaning robot, referring to Figure 1-Figure 3, including: a bottom shell 100, a shell 200, a first drive assembly 300, a second drive assembly 400 and a shearing assembly 500. The bottom shell 100 is detachably equipped with a roller brush for cleaning the floor (not shown in the drawings); the shell 200 is movably assembled on the bottom shell 100, and a second transmission member 210 is provided on one side of the shell 200. The first drive assembly 300 is fixedly arranged on the bottom shell 100, wherein the first drive assembly 300 includes: a first drive device 310 and a first transmission member 320. The first drive device 310 is provided with a first output shaft 311 arranged horizontally. The first transmission member 320 is fixedly sleeved on the first output shaft 311 and cooperates with the second transmission member 210 to make the shell 200 move forward or backward relative to the bottom shell 100 in the direction of the roller brush. The second drive assembly 400 is fixedly mounted on the housing 200 and includes: a second drive device 410 and an eccentric wheel 420; the second drive device 410 is fixedly mounted on the housing 200 and is provided with a second output shaft 411 arranged vertically; the eccentric wheel 420 is fixedly sleeved on the second output shaft 411, and the eccentric wheel 420 is provided with an eccentric shaft 421 extending away from the second output shaft 411. The shearing assembly 500 is mounted on the housing 200 and includes: a first shearing piece 510 and a second shearing piece 520; one end of the first shearing piece 510 is detachably mounted on the eccentric shaft 421; the second shearing piece 520 is detachably mounted on the housing 200 and is located in the same vertical direction as the first shearing piece 510. In this embodiment, the first shearing member 510 is detachably mounted on the eccentric shaft 421, which is fixedly mounted on the second output shaft 411. When the second drive device 410 is driven, the second output shaft 411 and the eccentric shaft 421 rotate, driving the first shearing member 510 to move under the influence of the eccentric shaft 421. The first shearing member 510 acts as a "moving blade," while the second shearing member 520, fixedly mounted on the housing 200, acts as a "fixed blade." The two shearing members cooperate to shear foreign matter, such as human or animal hair, filaments, or flocs. In this embodiment, the foreign matter is human or animal hair. In other embodiments, the foreign matter may also be filaments or flocs.

[0032] In this embodiment, referring to Figure 1-Figure 3The working process of the cleaning robot for shearing foreign objects is as follows: drive the first driving device 310, and the first transmission member 320 cooperates with the second transmission member 210 to make the shell 200 move relative to the bottom shell 100 toward the roller brush; under the action of the second driving device 410, the eccentric shaft 421 drives the first shearing member 510 to reciprocate relative to the second shearing member 520. Specifically, the first shearing member 510 performs horizontal reciprocating motion relative to the second shearing member 520, and the two cooperate to shear foreign objects on the roller brush, so that after the user uses the cleaning robot to clean the floor, the first driving component 300 and the second driving component 400 can be driven to shear foreign objects entangled on the roller brush in time, without the need for manual cleaning, which is convenient and fast, and greatly improves the efficiency of cleaning foreign objects on the roller brush. When the user needs to replace or repair the roller brush, the first drive device 310 is activated, driving the first output shaft 311 to rotate in the opposite direction. The first transmission member 320 cooperates with the second transmission member 210 to move the housing 200 relative to the bottom shell 100 away from the roller brush. This prevents the shear assembly 500 from injuring the user and improves the safety of the cleaning robot. In this embodiment, the first drive device 310 and the second drive device 410 are servo motors. In some embodiments, the first drive device 310 and the second drive device 410 can also be motors.

[0033] In this embodiment, referring to Figure 3-Figure 5 The cleaning robot further includes: a movable block 600 located between the first shearing member 510 and the eccentric shaft 421, movably assembled on the housing 200, and sleeved on one end of the eccentric shaft 421. The first shearing member 510 is detachably assembled on the side of the movable block 600 facing away from the eccentric shaft 421. Specifically, a movable hole 610 for inserting the eccentric shaft 421 is opened on the movable block 600. The eccentric shaft 421 is inserted into the movable hole 610. The first shearing member 510 is detachably assembled on the side of the movable block 600 facing away from the eccentric shaft 421. When the second driving device 410 is turned on, the eccentric shaft 421 cooperates with the movable block 600 to convert the circular motion of the second output shaft 411 into the horizontal shearing motion of the first shearing member 510. Finally, the first shearing member 510 and the second shearing member 520 cooperate to complete the shearing of foreign matter.

[0034] In some embodiments, the end of the eccentric shaft 421 close to the first shearing piece 510 can also be set as an eccentric nail. A groove is provided on the first shearing piece 510. The eccentric nail is placed at the groove position of the first shearing piece 510, and the circular motion of the second output shaft 411 can be converted into the horizontal shearing motion of the first shearing piece 510, thereby completing the function of shearing foreign matter.

[0035] In this embodiment, the first transmission member 320 is a gear, and the second transmission member 210 is a longitudinally disposed rack. The first transmission member 320 and the second transmission member 210 mesh with each other to cause the housing 200 to move relative to the bottom housing 100 toward the roller brush. When the first drive device 310 is activated, the first output shaft 311 rotates the gear. Since the rotating gear meshes with the longitudinally disposed rack, and since the rack is fixed, the rotational motion of the gear is converted into linear motion of the rack. Since the rack is fixed to the housing 200, this is further converted into linear motion of the housing 200, causing the housing 200 to perform longitudinal linear motion relative to the bottom housing 100. The meshing of the rack and gear is characterized by high precision and high reliability, ensuring stability and accuracy during movement. The combined structure of the gear and rack is relatively simple, making it easy to manufacture and maintain.

[0036] In some embodiments, the first transmission member 320 and the second transmission member 210 may also be a combination of a ball and a screw.

[0037] Further, refer to Figure 1 and Figure 3-Figure 5 The bottom shell 100 is provided with a support frame 110 that protrudes upward and has a cavity 111 therein. The support frame 110 is provided with a movable groove 112 that communicates with the cavity 111. In this embodiment, the support frame 110 and the housing 200 are arranged on the same straight line, and the roller brush can be detachably assembled in the cavity 111, making it convenient for users to replace the roller brush. When the first driving device 310 is turned on, the first transmission member 320 cooperates with the second transmission member 210 to move the housing 200 relative to the bottom shell 100 toward the support frame 110. The first shearing member 510 and the second shearing member 520 follow the movement of the housing 200 and extend into the movable groove 112 to shear foreign matter on the roller brush. Since there are foreign objects of varying depths wrapped around the roller brush, in this embodiment, the first transmission member 320 is a gear and the second transmission member 210 is a rack. The user can control the first drive device 310 to drive the gear to rotate, thereby controlling the meshing position of the gear and the rack, and thereby controlling the distance between the shell 200 and the support frame 110, and ultimately achieving the length of the first shearing member 510 and the second shearing member 520 extending into the movable groove 112, that is, the length entering the cavity 111, so as to cut the foreign objects of varying depths wrapped around the roller brush, and the cutting position is flexible.

[0038] In this embodiment, referring to Figure 3-Figure 5The housing 200 is provided with an upwardly extending mounting groove 220 on a side facing the shearing assembly 500. A pressing piece 700 is provided between the mounting groove 220 and the end of the shearing assembly 500 near the movable block 600. Specifically, in this embodiment, the second shearing member 520 is located above the first shearing member 510, which is near the mounting groove 220. The pressing piece 700 is recessed in the middle and has two sides extending upwardly at an angle. The upwardly extending portion of the pressing piece 700 abuts against the side of the first shearing member 510 facing the mounting groove 220, thereby abutting the first shearing member 510 toward the second shearing member 520. This makes the abutment between the first shearing member 510 and the second shearing member 520 tighter, ensuring that the first shearing member 510 and the second shearing member 520 are tightly fitted to complete the shearing operation. In addition, the pressing piece 700 can also provide additional support to prevent the side of the first shearing member 510 away from the movable block 600 from deviating due to insufficient support, thereby failing to cooperate with the second shearing member 520 to complete the shearing operation.

[0039] Further, refer to Figure 4-Figure 6 The cleaning robot also includes a cover 800 that is detachably mounted on the side of the housing 200 where the shearing assembly 500 is mounted. The cover 800 cooperates with the housing 200 to tightly cover the shearing assembly 500 on the housing 200, preventing the shearing assembly 500 from falling off and facilitating subsequent maintenance and replacement of the shearing assembly 500. The cover 800 is provided with a first mounting post 810 extending downward. The pressing piece 700 is provided with a first mounting hole 710. The first mounting post 810 extends into the first mounting hole 710 and cooperates with the mounting groove 220 to fix the pressing piece 700. Specifically, the first mounting hole 710 is provided in the middle recessed portion of the pressing piece 700 for the first mounting post 810 to be inserted. After the cover 800 is covered on the housing 200, the first mounting post 810 extends into the first mounting hole 710 and cooperates with the mounting groove 220 to fix the pressing piece 700.

[0040] In this embodiment, the pressing piece 700 is an elastic piece. In some embodiments, the pressing piece 700 can also be a spring.

[0041] Further, refer to Figure 4-Figure 6 The first shearing piece 510 is provided with a first avoidance hole 511 for avoiding the first mounting column 810, and the second shearing piece 520 is provided with a second avoidance hole 521 for avoiding the first mounting column 810 and corresponding to the position of the first avoidance hole 511, so as to prevent the first mounting column 810 from restricting the horizontal movement of the first shearing piece 510 relative to the second shearing piece 520.

[0042] In this embodiment, referring to Figure 4-Figure 6The first shearing piece 510 and the second shearing piece 520 overlap at their shearing locations, and the second shearing piece 520 is located between the cover 800 and the first shearing piece 510, while the first shearing piece 510 is located between the housing 200 and the second shearing piece 520. Furthermore, the cover 800 is provided with a second mounting post 820 extending downwardly. The second shearing piece 520 is provided with a second mounting hole 522. The second mounting post 820 cooperates with the second mounting hole 522 to secure the second shearing piece 520 between the cover 800 and the first shearing piece 510. The second shearing piece 520 is placed between the cover 800 and the first shearing piece 510, and the second mounting post 820 and the second mounting hole 522 cooperate to confine the two shearing pieces between the cover 800 and the first shearing piece 510, preventing the second shearing piece 520 from shifting or falling, while not hindering the horizontal movement of the first shearing piece 510, thereby facilitating installation and replacement.

[0043] In this embodiment, the width of the first shearing piece 510 is shorter than the width of the movable groove 112. When the shearing assembly 500 extends into the movable groove 112 and finally enters the cavity 111 of the support frame 110, the second driving device 410 is turned on, and the first shearing piece 510 performs horizontal shearing movement relative to the second shearing piece 520. The width of the first shearing piece 510 is shorter than the width of the movable groove 112, which makes it convenient for the first shearing piece 510 to perform horizontal shearing movement in the movable groove 112 after extending into the movable groove 112, thereby avoiding the movable groove 112 limiting the movement range of the first shearing piece 510, resulting in the inability to complete the shearing of foreign objects on the roller brush in the cavity 111 of the support frame 110.

[0044] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
