[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Please see Figure 1-4 This utility model provides a technical solution: a side brush structure for a robotic vacuum cleaner that simultaneously cleans and vacuums, comprising:

[0035] Connecting structure 1, the top of which is mounted on the robot vacuum cleaner;

[0036] The side brush housing 2 is assembled at the bottom of the connecting structure 1, and a through hole 3 is provided thereon. The outside of the through hole 3 is connected to the negative pressure generating device on the sweeping robot through the connector 4.

[0037] A side brush holder 5 is disposed inside the side brush housing 2, and a side brush 6 is assembled at its bottom. Several ventilation structures are provided on the side brush holder 5, and the ventilation structures are connected to the through hole 3.

[0038] Servo motor 9, whose rotation drive shaft is connected to the side brush holder 5.

[0039] When the above structure is in use, the servo motor 9 drives the side brush holder 5 to rotate, causing the side brush 6 to rotate. This sweeps the dust around the side brush structure to the area below the side brush holder 5. The negative pressure generating device operates, creating an inward-drawing airflow within the ventilation structure and connector 4, which draws the dust below the side brush holder 5 into the robot's filtration device for filtering and collection. This allows the side brush structure to integrate dust sweeping and vacuuming functions, achieving simultaneous sweeping and vacuuming and improving sweeping efficiency.

[0040] The ventilation structure includes external flow ports 7 spaced circumferentially on the side brush holder 5, and internal flow ports 8 extending outward from the external flow ports 7 and communicating with the inner cavity of the side brush housing 2. The external flow ports 7 are arc-shaped strips, and several internal flow ports 8 extend radially outward from the outer side of the external flow ports 7 and penetrate the side brush holder 5. As a result, when the servo motor 9 drives the side brush holder 5 and the side brush 6 to rotate, the ventilation structure rotates synchronously, and the negative pressure generating device creates a spiral inward airflow within the ventilation structure, thereby improving the dust collection performance and efficiency.

[0041] A support frame 10 is provided inside the side brush housing 2, and a sealing felt ring 11 is provided on the surface of the support frame 10. The sealing felt ring 11 abuts against the side brush seat 5. This provides support for the side brush seat 5, making it more stable when rotating.

[0042] The connection structure 1 includes a mounting plate 12, a first connecting seat 13, and a second connecting seat 14. The top of the mounting plate 12 is mounted on the sweeping robot, and the rotating block 15 at its bottom is rotatably mounted on the limiting port 16 of the first connecting seat 13 via a rotating shaft. Both the first connecting seat 13 and the rotating block 15 are provided with first mounting holes 17 that mate with the rotating shaft. Fasteners pass through the second mounting holes 18 of the first connecting seat 13 and the rotating block 15 to position the first connecting seat 13 and the rotating block 15. The first connecting seat 13 mates with the second connecting seat 14, and the second connecting seat 14 mates with the side brush housing 2. When the side brush needs to be replaced or maintained after a period of use, the fasteners are loosened, and the first connecting seat 13 and the second connecting seat 14 are pushed and pulled, causing the bottom of the side brush structure to flip along the rotating shaft, exposing the side brush 6 for replacement or maintenance. This simplifies the component replacement and maintenance process, eliminating the need for complete disassembly of the side brush and subsequent disassembly and reassembly of the side brush assembly, shortening the manual replacement time and improving ease of use.

[0043] The arc-shaped notch 19 on the surface of the limiting port 16 fits tightly against the surface of the rotating block 15 to improve the structural connection between the mounting plate 12 and the first connecting seat 13 and the stability of the relative sway of the structure.

[0044] An electric cylinder 20 is installed at the bottom of the first connecting seat 13, and the output end of the electric cylinder 20 is connected to the second connecting seat 14. This enables the side brush structure to be raised and lowered. The electric cylinder 20 drives the side brush structure to be raised and lowered, so that the distance between the side brush seat 5, the side brush 6 and the ground is controllable, thereby improving the dust collection efficiency of the ventilation structure on the side brush seat 5 and the cleaning efficiency of the side brush 6.

[0045] At least one elastic guide seat 21 is provided at the bottom of the second connecting seat 14. The movable shaft 22 is elastically slidably connected to the elastic guide seat 21 by a spring and docks with the third connecting seat 24 through a connecting block 23. The third connecting seat 24 is assembled on the fourth connecting seat 25 of the side brush housing 2. A position sensor 26 is provided at the bottom of the second connecting seat 14 on the moving path of the movable shaft 22. This allows the main body of the side brush structure to elastically dock with the connecting structure 1 through the movable shaft 22. When the side brush structure comes into contact with an obstacle and is about to collide, the main body of the side brush structure is pushed, causing the movable shaft 22 to slide along the elastic guide seat 21. The position sensor 26 senses the movement of the movable shaft 22 and associates it with the controller of the sweeping robot to achieve emergency braking and stop, avoiding damage to the components due to collision. When the side brush structure disengages from the obstacle, the force on the main body of the side brush structure is removed, and it automatically resets and resumes normal operation through the spring. The position sensor 26 can be a pressure sensor. When the movable shaft 22 presses against the position sensor 26, the position sensor 26 senses the pressing force and performs associated braking. Of course, the position sensor 26 can also be other types of sensors to realize robot associated braking based on the motion sensing of the movable shaft 22.

[0046] In summary, due to the adoption of the above technical solution, the side brush structure of the robotic vacuum cleaner with simultaneous cleaning and vacuuming in this embodiment has the following advantages compared with the prior art:

[0047] This utility model's robotic vacuum cleaner side brush structure, through the arrangement of a side brush base with ventilation, a side brush, a servo motor, and a connector for a negative pressure generator, achieves a multi-functional integrated design for floor sweeping and vacuuming, enabling simultaneous sweeping and vacuuming and improving sweeping efficiency. The rotating block's connection to the first connecting seat and the fastener locking mechanism simplify the component replacement and maintenance process, eliminating the need for complete disassembly of the side brush before assembly, shortening manual replacement time and improving ease of use. The electric cylinder drives the side brush structure's lifting and lowering, making the distance between the side brush base / brush and the ground controllable, thereby improving the vacuuming efficiency of the ventilation structure on the side brush base and the sweeping efficiency of the side brush. The main body of the side brush structure is elastically connected via a movable shaft and, in conjunction with a positioning sensor, can detect obstacles and perform emergency braking, preventing collisions that could damage components and extending their lifespan.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
