[0037] In one embodiment of this utility model, such as Figure 1-7 As shown, a brush disc for a robotic vacuum cleaner is provided, comprising: a disc body 1, a main hollow area 2, and a secondary hollow groove 3. The parts mounting area is formed by the main hollow area 2; the disc body 1 has an inner ring and an outer ring, respectively, for the parts mounting area and the bristle mounting area; the main hollow area 2 includes an opening 201, a mounting platform 202, an arc-shaped strip 203, and a connecting straight strip 204. The opening 201 is located at the center of the disc body 1, and the mounting platform 202 is located at the center of the opening 201; the arc-shaped strip 203 is positioned between the mounting platform 202 and the opening 201, and both ends of the arc-shaped strip 203 are connected to the inner wall of the opening 201. The strip 203 bends along the direction of the mounting platform 202, and several arc-shaped strips 203 are provided symmetrically at intervals with the mounting platform 202 as the center; the connecting straight strip 204 is provided between the connection intersection of at least two arc-shaped strips 203 and the edge of the mounting platform 202; the secondary hollow groove 3 is provided with several strips, which are respectively recessed in the mounting platform 202, the arc-shaped strips 203 and the connecting straight strips 204; the disc body 1, the mounting platform 202, the arc-shaped strips 203, the connecting straight strips 204 and the secondary hollow groove 3 are integrally formed.

[0038] This utility model provides a brush disc for a robotic vacuum cleaner, employing a main hollow area 2 and a secondary hollow groove 3 to form a lightweight hollow composite structure, effectively reducing the weight of the disc body 1. By setting the main hollow area 2, while reducing the overall weight, the design of the disc body 1, mounting platform 202, arc-shaped strip 203, and connecting straight strip 204 ensures the brush disc has sufficient structural strength and stability, guaranteeing efficient operation of the robotic vacuum cleaner. By setting the secondary hollow groove 3 on the mounting platform 202, arc-shaped strip 203, and connecting straight strip 204, the amount of material used is reduced, lowering the overall weight and effectively reducing the load on the robotic vacuum cleaner. The integrated molding of the disc body 1, mounting platform 202, arc-shaped strip 203, connecting straight strip 204, and secondary hollow groove 3 avoids the need for splicing between parts, effectively reducing friction and collision noise between parts, and eliminating the need for additional connectors, thus directly reducing the overall weight. This makes the robotic vacuum cleaner operate more quietly and flexibly, creating a more comfortable cleaning environment for users.

[0039] Specifically, the main hollow area 2 includes an opening 201, a mounting platform 202, an arc-shaped strip 203, and a connecting straight strip 204. The opening 201 is located at the center of the disk body 1, and the mounting platform 202 is located at the center of the opening 201. The arc-shaped strip 203 is positioned between the mounting platform 202 and the opening 201, with both ends of the arc-shaped strip 203 connected to the inner wall of the opening 201. The arc-shaped strip 203 bends along the direction of the mounting platform 202, allowing external forces to be distributed more evenly on the brush disk structure, effectively avoiding local stress concentration, reducing the risk of deformation or damage caused by excessive local stress, and enhancing the overall durability and reliability of the structure.

[0040] Among them, several arc-shaped strips 203 are arranged symmetrically around the mounting platform 202. In this embodiment, the arc-shaped strips 203 are arranged symmetrically around the mounting platform 202 to form multiple support points, which not only enhances the structural strength, but also effectively disperses the external forces generated during operation and prevents deformation or damage caused by uneven local stress.

[0041] Furthermore, the connecting straight bar 204 is disposed between the connection point of at least two arc-shaped bars 203 and the edge of the mounting platform 202, forming a stable triangular reinforcement and stress transmission structure, which effectively transmits the external force on the arc-shaped bars 203 to the mounting platform 202 evenly and efficiently, thereby enhancing the overall structural rigidity.

[0042] Preferably, the disc body 1 is circular. In other embodiments, the disc body 1 can also be a circular rectangle, square, or other shapes that meet the usage requirements.

[0043] Preferably, the surface of the disc body 1 is provided with brush holes 401, forming a brush mounting area 4. The orientation of the brush holes 401 is the same as the recessed direction of the secondary hollow groove 3. The co-directional layout of the brush holes 401 and the secondary hollow groove 3 allows the brush mounting area 4 and the secondary hollow groove area to effectively disperse external forces during operation, improving the cleaning stability of the sweeping robot.

[0044] Preferably, the outer ring of the disk body 1 is provided with a plurality of openings 5, which are centrally symmetrically arranged around the mounting platform 202 on the outer ring of the disk body 1. The arrangement of the openings 5 ​​reduces the amount of material used in the disk body 1, and further realizes the lightweighting of the brush disk without affecting the overall structural strength of the brush disk.

[0045] Preferably, the outer ring of the disk body 1 is provided with weight-reducing grooves 6, and there are several weight-reducing grooves 6. The several weight-reducing grooves 6 are centrally symmetrically opened on the outer ring of the disk body 1 with the mounting platform 202 as the center. The weight-reducing grooves 6 directly reduce the amount of material used in the disk body 1, further realizing the lightweighting of the brush disk, and also making it easier to open brush bristle holes 401 on the side of the disk body 1.

[0046] Preferably, the mounting platform 202 is provided with a positioning port 7 and connecting holes 8. The positioning port 7 is located at the center of the mounting platform 202, and several connecting holes 8 are arranged symmetrically around the positioning port 7 along the outer ring of the mounting platform 202. The positioning port 7 provides a clear positioning for the docking of the brush plate and the drive shaft of the sweeping robot, reducing installation errors, ensuring that the brush plate is in the center position during initial installation, ensuring the dynamic balance of the brush plate during high-speed rotation, avoiding vibration and noise caused by installation deviations, and improving the stability and reliability of the sweeping robot operation.

[0047] Furthermore, the brush plate used by the sweeping robot also includes a first groove 9 and a second groove 10 with the same recess direction as the secondary hollow groove 3. The first groove 9 is opened on the table surface of the mounting platform 202, and the second groove 10 is opened on the inner bottom surface of the first groove 9. Several connecting bars 204 are arranged radiating outward from the periphery of the mounting platform 202 with the mounting platform 202 as the center. The opening end 15 of the first groove 9 and the opening end 15 of the second groove 10 are both opened between adjacent connecting bars 204, and both shrink from the outer circle of the mounting platform 202 to the inner circle of the mounting platform 202. The opening end 15 of the first groove 9 and the opening end 15 of the second groove 10 are opposite to each other.

[0048] In this embodiment, the opening ends 15 of the first and second grooves are located between adjacent connecting straight bars 204, contracting from the outer ring to the inner ring of the mounting platform 202 and facing each other. When the brush disk rotates, the contraction structure of the opening ends 15 of the first and second grooves promotes the acceleration and convergence of airflow. The airflow speed increases in the contraction channel, which, in conjunction with the airflow guided by the secondary hollow groove 3, can reduce the air resistance when the brush disk rotates and reduce the noise generated by air friction.

[0049] Specifically, the mounting platform 202 is equipped with a connector for positioning the disk body 1.

[0050] Furthermore, the connector includes a positioning plate 11 and a fastening pin 12. One end of the positioning plate 11 is a circular locking end, and the other end is a rounded rectangle, which guides the positioning plate 11 to quickly insert into the positioning port 7, shortening the installation time and reducing the installation difficulty. The diameter of the circular locking end of the positioning plate 11 is larger than the diameter of the rounded rectangle end of the positioning plate 11. When the positioning plate 11 is inserted into the positioning port 7, the circular locking end forms a limiting structure, effectively preventing the positioning plate 11 from axially moving or shaking within the positioning port 7, thus enhancing the stability of the positioning. The circular locking end of the positioning plate 11 is provided with a mating hole for engaging with the connecting hole 8, and the rounded rectangle end of the positioning plate 11 is provided with an insertion hole. The fastening pin 12 passes through the insertion hole and connects with the insertion hole, effectively preventing brush plate displacement or detachment due to unstable connection, ensuring the stable and efficient operation of the sweeping robot.

[0051] Preferably, the secondary hollow groove 3 on the surface of any arc-shaped strip 203 is provided with at least one connecting circular block 13 or connecting elongated block 14, wherein the diameter of the connecting circular block 13 is smaller than the length of the connecting elongated block 14. The connecting circular block 13 or connecting elongated block 14 acts as an additional support node, and these block structures can effectively disperse stress when the brush plate is subjected to external force during the operation of the sweeping robot.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
