Description

Technical Field

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

[0002] A robot vacuum, also known as an automatic sweeper, smart vacuum, or robotic vacuum cleaner, is a household appliance that automatically cleans floors in a room. It relies primarily on infrared radiation for navigation and positioning, and has a built-in vacuum system to absorb debris such as dust and debris. These robots typically use a brushing and vacuuming method to first suck debris into their own waste collection bin, completing the cleaning process. Generally, a robot vacuum is controlled by a microcomputer and can perform functions such as automatic navigation, obstacle avoidance, scheduled scheduling, and automatic recharging. It is a type of smart home appliance that brings great convenience to people's daily lives.

[0003] Most existing sweeping robots can only clean the floor surface and are unable to effectively clean the bottom of walls and corners, resulting in poor cleaning results in these areas, reducing the practicality and user experience of sweeping robots. Therefore, a new cleaning mechanism is needed that can effectively clean the bottom of walls and corners. Utility Model Content

[0004] In view of the existing deficiencies, the utility model provides a cleaning mechanism for an indoor sweeping robot, which solves the problem that the existing sweeping robots can only clean the ground surface but cannot effectively clean the bottom of the wall and the corners.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A cleaning mechanism of an indoor sweeping robot comprises a first upright plate and a second upright plate, the second upright plate being disposed behind the first upright plate, a telescopic assembly being disposed between the first and second upright plates, a connecting plate being fixedly disposed on the left side of the first upright plate, and two groups of cleaning units being disposed on the left side of the connecting plate;

[0007] The cleaning unit includes a belt, a support shaft, a bracket, a pulley, a transmission wheel, a cleaning belt, a cleaning brush, a driven bevel gear, an active bevel gear and a driving motor. The bracket is arranged to have a hollow right-angled triangle structure, and its right end is fixedly connected to the connecting plate. The three corners inside the bracket are penetrated by the support shaft, and a transmission wheel is assembled on the support shaft on the lower side of the bracket. The transmission wheels are connected by a cleaning belt transmission. A cleaning brush is fixed on the lower end of the cleaning belt, and a pulley is assembled on the support shaft on the upper side of the bracket. The pulleys are connected by a belt transmission. The upper end of the support shaft at the right angle on the bracket is equipped with a driven bevel gear, and the driving motor is assembled on the connecting plate. The output end of the driving motor is equipped with a driving bevel gear, and the driving bevel gear is meshed with the driven bevel gear for transmission connection.

[0008] Furthermore, a first top plate is fixed on the top of the first vertical plate, a second top plate is fixed on the top of the second vertical plate, a slider is fixed on the first top plate, a slide rail is fixed on the second top plate, and the slider is slidably connected with the slide rail.

[0009] Furthermore, the cleaning unit is a right triangle structure as a whole, and the two groups of cleaning units are arranged in a right triangle structure, and after the cleaning unit is assembled on the sweeping robot body, its overall longitudinal width is greater than the width of the sweeping robot body.

[0010] Furthermore, the telescopic assembly comprises a front fixing frame, a cross link, a rear fixing frame, an electric push rod, a first connecting shaft, a slide groove and a second connecting shaft, the front fixing frame is fixedly connected to the first vertical plate, the rear fixing frame is fixedly connected to the second vertical plate, two groups of cross links with X-shaped structures are provided between the front fixing frame and the rear fixing frame, the two left ends of the cross links are connected to the front fixing plate through the first connecting shaft, the upper and lower ends of the front fixing frame are provided with slide grooves, and the first connecting shaft on the rear side of the front fixing frame is stuck in the slide groove, the two right ends of the cross links are connected to the rear fixing plate through the second connecting shaft, the two groups of the second connecting shafts are connected by an electric push rod, and the second connecting shaft on the rear side of the rear fixing frame is slidably connected to them.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The utility model can effectively clean the bottom and corners of the wall through two sets of cleaning units with a right-angled triangle structure, has strong adaptability, significantly improves the cleaning effect, and ensures the overall cleanliness of the indoor environment.

[0013] 2. In the utility model, a first top plate is fixed on the top of the first vertical plate, a second top plate is fixed on the top of the second vertical plate, a slider is fixed on the first top plate, and a slide rail is fixed on the second top plate. The slider and the slide rail are slidably connected with each other. This design further enhances the stability of the entire cleaning mechanism. At the same time, the sliding connection between the slider and the slide rail enhances the stability of the entire cleaning mechanism during movement, ensuring that the cleaning mechanism will not loosen or shift during the cleaning process.

[0014] 3. The utility model's right-angled triangle structure allows the cleaning unit to fit snugly into wall corners, effectively cleaning these areas. This ensures the cleaning brush can reach deep into corners, removing hard-to-reach dust and dirt, and enhancing cleaning effectiveness. Furthermore, when the cleaning unit is mounted on the robot vacuum, its overall longitudinal width is greater than the robot's width. This design allows the outer end of the cleaning unit to extend beyond the robot's body, facilitating cleaning of the bottom of the wall without leaving any blind spots, thus improving cleaning efficiency and effectiveness.

[0015] 4. The telescopic assembly provided in the present invention can control the telescopic movement of the cleaning unit to adapt to cleaning work in different positions. When the electric push rod is started, it will pull the second connecting shaft to move forward. Due to the X-shaped structure of the cross-link, when the second connecting shaft moves backward, it will drive the cross-link to rotate and extend, while increasing the distance between the front fixing frame and the rear fixing frame, thereby driving the cleaning unit to move forward and extend from the bottom of the sweeping robot, making it easier to clean the corners. Conversely, when the electric push rod is extended, the second connecting shaft moves backward, driving the cross-link to rotate and compress, thereby reducing the distance between the front fixing frame and the rear fixing frame, thereby driving the cleaning unit to retract and retract it to the bottom of the sweeping robot, making it easier to clean the flat bottom area without taking up too much space.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example:

[0028] like Figures 1 to 9 As shown, a cleaning mechanism of an indoor sweeping robot comprises a first upright plate 1 and a second upright plate 3. The second upright plate 3 is provided on the rear side of the first upright plate 1. A telescopic assembly 2 is provided between the first upright plate 1 and the second upright plate 3. A connecting plate 6 is fixedly provided on the left side of the first upright plate 1. Two groups of cleaning units 5 are provided on the left side of the connecting plate 6.

[0029] The cleaning unit 5 includes a belt 51, a support shaft 52, a bracket 53, a pulley 54, a transmission wheel 55, a cleaning belt 56, a cleaning brush 57, a driven bevel gear 58, an active bevel gear 59 and a drive motor 510. The bracket 53 is set to a hollow right-angled triangle structure, and its right end is fixedly connected to the connecting plate 6. The three corners of the bracket 53 are all penetrated by the support shaft 52. The transmission wheel 55 is installed on the support shaft 52 on the lower side of the bracket 53. The transmission wheels 55 are connected by a cleaning belt 56. A cleaning brush 57 is fixed at the lower end of the cleaning belt 56. A pulley 54 is installed on the support shaft 52 on the upper side of the frame 53, and the pulleys 54 are connected by a belt 51. The upper end of the support shaft 52 at a right angle on the bracket 53 is equipped with a driven bevel gear 58, and the connecting plate 6 is equipped with a driving motor 510. The output end of the driving motor 510 is equipped with an active bevel gear 59, and the active bevel gear 59 is meshed with the driven bevel gear 58 for transmission connection. This design solves the problem that most existing intelligent sweeping robots can only clean the ground surface, and cannot effectively clean the bottom of the wall and the corners, resulting in poor cleaning effect.

[0030] In this embodiment, a first top plate 8 is fixedly mounted on top of the first upright plate 1, and a second top plate 4 is fixedly mounted on top of the second upright plate 3. A slider 7 is fixedly mounted on the first top plate 8, and a slide rail 9 is fixedly mounted on the second top plate 4. The slider 7 and the slide rail 9 are slidably connected. This design further enhances the stability of the entire cleaning mechanism. The slidable connection between the slider 7 and the slide rail 9 enhances the stability of the entire cleaning mechanism during movement, ensuring that the cleaning mechanism will not loosen or shift during the cleaning process.

[0031] In this embodiment, the cleaning units 5 are generally shaped like a right triangle, with two groups of cleaning units 5 arranged in a right triangle configuration. When the cleaning units 5 are mounted on the robot vacuum, their overall longitudinal width is greater than the width of the robot vacuum. This right triangle configuration allows the cleaning units 5 to fit snugly into corners, effectively cleaning these areas and ensuring that the cleaning brushes 57 can reach deep into these corners, removing hard-to-reach dust and dirt and enhancing the cleaning effect. Furthermore, when the cleaning units 5 are mounted on the robot vacuum, their overall longitudinal width is greater than the width of the robot vacuum. This design allows the outer ends of the cleaning units 5 to extend beyond the robot vacuum, facilitating cleaning of the bottom portion of the wall without leaving any blind spots, thereby improving cleaning efficiency and effectiveness.

[0032] In this embodiment, the telescopic assembly 2 comprises a front fixing frame 21, a cross link 22, a rear fixing frame 23, an electric push rod 24, a first connecting shaft 25, a slide 26, and a second connecting shaft 27. The front fixing frame 21 is fixedly connected to the first vertical plate 1, and the rear fixing frame 23 is fixedly connected to the second vertical plate 3. Two sets of X-shaped cross links 22 are disposed between the front fixing frame 21 and the rear fixing frame 23. The left ends of the cross links 22 are connected to the front fixing plate via the first connecting shaft 25. Slide grooves 26 are defined at both the upper and lower ends of the front fixing frame 21, and the first connecting shaft 25 on the rear side of the front fixing frame 21 snaps into the slide grooves 26. The right ends of the cross links 22 are connected to the rear fixing plate via the second connecting shaft 27. The two sets of second connecting shafts 27 are connected by the electric push rod 24, and the second connecting shaft 27 on the rear side of the rear fixing frame 23 is slidably connected to the second connecting shaft 27. The telescopic assembly 2 can control the telescopic movement of the cleaning unit 5 to accommodate cleaning operations at different locations. When the electric push rod 24 is activated, it pulls the second connecting shaft 27 forward. Due to the X-shaped structure of the cross-link 22, when the second connecting shaft 27 moves backward, it drives the cross-link 22 to rotate and extend, and at the same time increases the distance between the front fixing frame 21 and the rear fixing frame 23, thereby driving the cleaning unit 5 forward and extending from the bottom of the sweeping robot to facilitate cleaning corners. Conversely, when the electric push rod 24 extends, the second connecting shaft 27 moves backward, driving the cross-link 22 to rotate and compress, causing the distance between the front fixing frame 21 and the rear fixing frame 23 to decrease, thereby driving the cleaning unit 5 to retract and retract it to the bottom of the sweeping robot, making it easier to clean flat bottom areas without taking up too much space.

[0033] The working principle of the cleaning mechanism of an indoor sweeping robot is as follows: first, the second vertical plate 3 and the second top plate 4 in the mechanism are fixedly connected to the sweeping robot, the first vertical plate 1 is connected to the second vertical plate 3 through the telescopic component 2, and the slider 7 on the first top plate 8 is matched with the slide rail 9 on the second top plate 4. In actual use, when cleaning a flat floor, the telescopic assembly 2 is in a compressed state. At this time, the cleaning unit 5 is located at the bottom of the robot body. The driving wheel 55 on the cleaning unit 5 drives the cleaning belt 56 to rotate, and the cleaning belt 56 drives the cleaning brush 57 to rotate to clean the floor. At the same time, since the overall longitudinal width of the cleaning unit 5 after being assembled on the robot body is greater than the width of the robot body, the outer end of the cleaning unit 5 can extend out of the robot body, thereby facilitating the cleaning of the bottom of the wall without leaving any blind spots, thereby improving the cleaning efficiency and effect. When it is necessary to clean the corner area, the electric push rod 24 in the telescopic assembly 2 is activated and controlled to retract. The electric push rod 24 pulls the second connecting shaft 27 to move forward. Due to the X-shaped structure of the cross link 22, when the second connecting shaft 27 moves backward, it drives the cross link 22 to rotate and extend, and at the same time increases the distance between the front fixing frame 21 and the rear fixing frame 23, thereby driving the cleaning unit 5 to move forward and extend from the bottom of the robot body, making it convenient to clean the corner area.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
