[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are only for the purpose of describing specific embodiments and are not intended to limit this invention. Figures 1 to 4As shown, in one embodiment of the present invention, a single-drive double-roller mechanism for sweeping and cleaning is involved, including a base plate 1, a cleaning component 2, a roller brush component 3, a driving component 4 and a linkage component 5. The base plate 1 is provided with a roller brush bin 11, the cleaning component 2 is provided on the base plate 1 and is located on one side of the roller brush bin 11, the roller brush component 3 is provided in the roller brush bin 11, the driving component 4 is provided on one side of the roller brush bin 11 and is driven and connected to the roller brush component 3, the linkage component 5 includes a linkage base 51, a linkage shaft 52, a transmission belt Belt 53 and linkage element 54, the linkage base 51 is set on the bottom plate 1, the linkage shaft 52 is rotatably set on the linkage base 51, and the linkage element 54 is set on the linkage shaft 52. One end of the transmission belt 53 is connected to the linkage shaft 52 and the other end is connected to the driving component 4. When the driving component 4 drives the roller brush assembly 3 to rotate, it also drives the linkage shaft 52 to rotate; the linkage element 54 is connected to the cleaning component 2 to drive the cleaning component 2 to rotate, and the cleaning component 2 cleans the garbage and dust towards the roller brush bin 11. This embodiment uses a single driving component 4 to drive the roller brush assembly 3 and the cleaning component 2 at the same time, realizing the sharing and maximum utilization of the power source, effectively reducing energy consumption and manufacturing costs. The roller brush assembly 3 rotates at high speed under the direct action of the driving component 4, effectively peeling off and rolling up ground stains and stubborn dirt, while the cleaning component 2 is indirectly driven through the linkage mechanism and rotates synchronously to assist in collecting garbage and dust at the edge and front end. The design of the linkage assembly 5, especially the precise coordination of the linkage shaft 52, the transmission belt 53 and the linkage element 54, ensures efficient and stable power transmission. This design not only simplifies the transmission structure and reduces energy loss during the transmission process, but also improves the overall stability and durability of the system, reducing maintenance costs and failure rates. The rotary cleaning method of the cleaning assembly 2, combined with its cleaning path planning toward the roller brush bin 11, effectively promotes the directional concentration of garbage and dust, creating favorable conditions for the subsequent deep cleaning of the roller brush assembly 3. This collaborative operation mode greatly improves the efficiency and effectiveness of the cleaning operation, making the cleaning process smoother and more efficient.
[0025] Power installation areas 12 are located on either side of the base plate 1. Steering wheels 13 are installed on one side of the base plate 1, forming a triangular arrangement with the power installation areas 12. In this embodiment, the steering wheels 13 on one side of the brush chamber 11 form a stable triangular support structure with the power installation areas 12, greatly enhancing the robot's flexibility and maneuverability in complex terrain. This triangular arrangement effectively disperses stress during operation, making the robot vacuum more stable when turning, avoiding obstacles, or navigating small obstacles, reducing vibration and noise, and extending the robot's service life.
[0026] There are two groups of cleaning components 2, and the two groups of cleaning components 2 are respectively arranged on both sides of the base plate 1. Specifically, the cleaning component 2 includes a cleaning rotating element 21, a cleaning rotating gear 22 and a cleaning brush 23. The cleaning rotating element 21 is arranged on the base plate 1, and the cleaning rotating gear 22 is arranged on the cleaning rotating element 21. One end of the cleaning brush 23 is connected to the cleaning rotating element 21, and the cleaning rotating element 21 is connected to the linkage element 54 in a transmission connection. In this embodiment, the design of two groups of cleaning components 2 being respectively deployed on both sides of the base plate 1 demonstrates a high degree of functional integration and efficiency optimization. This configuration uses the cleaning rotating element 21 as the core power transmission medium, combined with the precise transmission of the cleaning rotating gear 22, to ensure that the cleaning brush 23 can operate at a stable and efficient speed. The cleaning brush 23 is directly connected to the cleaning rotating element 21, effectively utilizing the powerful power of the single drive source, realizing bilateral synchronous cleaning, and significantly expanding the coverage area of a single cleaning. The application of the linkage element 54 not only simplifies the mechanical structure, but also enhances the coordination between the components, so that the two-group cleaning operation can work closely together and clean the ground without dead angles.
[0027] The cleaning rotating element 21 is a rotating gear, and the linkage element 54 is a rotating pinion. The rotating pinion meshes with the rotating gear to drive the rotating gear. In this embodiment, the precise meshing of the rotating pinion and the rotating gear enables the efficient distribution and transmission of power from a single input to the dual rollers, significantly enhancing the smoothness and reliability of power transmission. The rotating gear, as the cleaning actuator, directly acts on the ground through its rotational motion, effectively improving cleaning coverage and efficiency. At the same time, the gear transmission reduces energy loss during the transmission process, ensuring sustained power for the cleaning operation.
[0028] The roller brush assembly 3 includes a roller brush bracket 31 and a cleaning roller brush 32 mounted on the roller brush bracket 31. The roller brush bracket 31 is arranged on one side of the roller brush compartment 11. The two ends of the cleaning roller brush 32 are rotatably mounted on the roller brush bracket 31. The cleaning roller brush 32 is located on the upper side of the roller brush compartment 11. Specifically, the drive assembly 4 includes a drive bracket 41, a drive motor 42, and a drive connection element 43. The drive bracket 41 is arranged on one side of the roller brush bracket 31. The drive motor 42 is mounted on the drive bracket 41. One end of the drive connection element 43 is connected to the drive motor 42 and the other end is connected to the cleaning roller brush 32. In this embodiment, by cleverly placing the roller brush bracket 31 on one side of the roller brush compartment 11, not only is the cleaning roller brush 32 fully exposed to the area to be cleaned, but it also facilitates subsequent maintenance and replacement. The two ends of the cleaning roller brush 32 are rotatably mounted on the roller brush bracket 31, enhancing operational stability and durability while ensuring uniform cleaning results.
[0029] The linkage shaft 52 is provided with a synchronous pulley 521. One end of the drive coupling element 43 is connected to the drive belt 53, and the other end is connected to the synchronous pulley 521. This embodiment achieves efficient power transmission and distribution, allowing both cleaning rollers to rotate simultaneously from a single drive source, simplifying the transmission system and reducing overall energy consumption and manufacturing costs. The use of the synchronous pulley 521 ensures the synchronization and precision of the rotation of the two rollers, avoiding uneven cleaning caused by speed differences, and improving cleaning efficiency and quality.
[0030] Multiple linkage bases 51 are provided, and the linkage shaft 52 is rotatably mounted on the multiple linkage bases 51. In this embodiment, by dispersing the support points, the stability and load-bearing capacity of the linkage shaft 52 are effectively enhanced, allowing a single drive source to more evenly and efficiently drive the dual rollers to rotate synchronously, reducing wear and failure that may be caused by the concentration of a single force point.
[0031] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
