Description

Technical Field

[0001] This utility model relates to the field of sweeping robot technology, specifically to a side brush extension mechanical structure. Background Technology

[0002] A robotic vacuum cleaner is a smart home appliance that uses built-in sensors, navigation systems, and cleaning components to move automatically in the indoor environment and complete the task of cleaning the floor.

[0003] During the cleaning process, the side brush is one of the important cleaning components of the robot vacuum cleaner. The side brush is usually installed at the bottom edge of the robot vacuum cleaner. Its main function is to sweep the dust and debris on both sides and in the corners of the robot's direction of travel toward the robot's suction port area so that they can be sucked into the dust collection box.

[0004] Currently, most robotic vacuum cleaners on the market have relatively fixed side brush positions. When the robot moves, the side brush cleans at a fixed angle and range. The side brush of the robotic vacuum cleaner cannot swing outward, resulting in defects such as incomplete corner cleaning, blind spots in edge cleaning, and difficulty in cleaning around obstacles. Multiple cleanings are required to achieve the desired effect, resulting in a poor user experience. Utility Model Content

The drive component is connected to the swing arm bracket, and the side brush component is assembled on the swing arm bracket. The drive component drives the swing arm bracket to rotate, and the swing arm bracket drives the side brush component to rotate.

[0007] Furthermore, the drive assembly includes a drive component, a transmission gear, and a rotating component. The rotating component is provided with a meshing part and is connected to the swing arm bracket. The drive component drives the transmission gear to rotate, and the transmission gear drives the rotating component to rotate through the meshing part. The rotating component drives the swing arm bracket to rotate.

[0008] Furthermore, the inner wall of the rotating component is provided with at least one pushing block, the swing arm bracket has movable slots corresponding to the number of pushing blocks, and there is a protrusion between two adjacent movable slots.

[0009] Furthermore, a connecting part is provided on one side of the swing arm bracket, and the connecting part is equipped with a torsion spring for connecting with the housing of the sweeping robot.

[0010] Furthermore, it also includes a base for mounting the drive assembly and the swing arm assembly, the base being equipped with a first limiting block and a second limiting block for limiting the rotation angle of the swing arm support.

[0011] Furthermore, the side brush assembly includes a drive body, a mounting shell, a side brush, and a transmission component. One side of the mounting shell is provided with a fixing member for assembling the drive body, the side brush is assembled on the other side of the mounting shell, and the transmission component is assembled inside the mounting shell.

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 protection scope of the present utility model.

[0027] like Figures 1-2 As shown, the robotic vacuum cleaner includes a housing 100, and the housing 100 is equipped with at least one side brush extending mechanical structure 200, such as... Figures 3-7 As shown, a side brush extension mechanical structure includes a drive component, a swing arm bracket 202, and a side brush assembly 300. The drive component is connected to the swing arm bracket 202, and the side brush assembly 300 is mounted on the swing arm bracket 202. The drive component drives the swing arm bracket 202 to rotate, and the swing arm bracket 202 drives the side brush assembly 300 to rotate.

[0028] The side brush assembly 300 includes a drive body 301, a mounting shell 303, a side brush 305, and a transmission component. A fixing member 302 for mounting the drive body 301 is provided on one side of the mounting shell 303. The drive body 301 and the fixing member 302 are connected by bolts. The side brush 305 is mounted on the other side of the mounting shell 303. The transmission component is mounted inside the mounting shell 303. The drive body 301 drives the side brush 305 to rotate through the transmission component. Specifically, the transmission component includes a turbine, a gear set 306, and a driven gear 304. The drive body 301 is a conventional servo motor. The drive body 301 drives the turbine to rotate. The turbine meshes with the gear set 306. The gear set 306 further meshes with the driven gear 304. The driven gear 304 is connected to the side brush 305 and drives the side brush 305 to rotate.

[0029] The fixing member 302 is provided with at least one limiting slot 307, and the swing arm bracket 202 is provided with limiting protrusions 212 corresponding to the number of limiting slots 307. The swing arm bracket 202 is fitted onto the fixing member 302, and the limiting protrusions 212 are inserted into the interior of the limiting slots 307, thereby causing the swing arm bracket 202 to drive the mounting shell 303 to rotate in the same direction.

[0030] It also includes a base 204 for mounting the drive assembly and the swing arm assembly, the base 204 being equipped with a first limiting block 203 and a second limiting block 208 for limiting the rotation angle of the swing arm bracket 202;

[0031] The drive assembly includes a drive component 209, a transmission gear 205, and a rotating component 207. The rotating component 207 is provided with a meshing part 206 and is connected to the swing arm bracket 202. The inner wall of the rotating component 207 is provided with at least one push block 214. The swing arm bracket 202 has movable slots 210 corresponding to the number of push blocks 214, and there is a protrusion 213 between two adjacent movable slots 210. The rotating component 207 is fitted onto the swing arm bracket 202, and the push blocks 214 are located in the movable slots 210. A connecting part 211 is provided on one side of the swing arm bracket 202. The connecting part 211 is equipped with a torsion spring 201 for connecting with the robot vacuum cleaner housing 100. Preferably, the connecting part 211 is provided with a connecting rod, and the top end of the connecting rod is provided with a barb to prevent the torsion spring 201 from disengaging from the connecting rod.

[0032] The driving component 209 is a conventional servo motor. The driving component 209 drives the transmission gear 205 to rotate. The transmission gear 205 drives the rotating component 207 to rotate through the meshing part 206. The rotating component 207 drives the swing arm bracket 202 to rotate. The swing arm bracket 202 drives the mounting shell 303 to rotate, so that the side brush 305 has two working states: the side brush 305 swings out and the side brush 305 retracts.

[0033] 1. With the side brush 305 in the retracted state, the drive component 209 drives the transmission gear 205 to rotate counterclockwise. The transmission gear 205 meshes with the meshing part 206, causing the rotating component 207 to rotate clockwise. The pushing block 214 slides in the movable groove 210 until it contacts the protrusion 213 on the left side. The rotating component 207 continues to rotate, and the pushing block 214 pushes the swing arm bracket 202 to rotate clockwise through the protrusion 213. The mounting shell 303 also rotates clockwise until the connecting part 211 is blocked by the first limit block 203. At this time, the torsion spring 201 is in a tensioned state, the mounting shell 303 is parallel to the base 204, and the side brush 305 is in the retracted state.

[0034] 2. When the side brush 305 is in the outward swing state, the driving component 209 drives the transmission gear 205 to rotate clockwise. The transmission gear 205 meshes with the meshing part 206, and causes the rotating component 207 to rotate counterclockwise. The pushing block 214 slides away from the left protrusion 213. The swing arm bracket 202 rotates counterclockwise under the tension of the torsion spring 201 until the connecting part 211 is blocked by the second limiting block 208. The mounting shell 303 and the base 204 have an inclined angle, and the side brush 305 is in the outward swing state. In this embodiment, the outward swing angle of the side brush 305 is 60°.

[0035] Compared with traditional technology: the drive component 209 drives the transmission gear 205 to rotate, the transmission gear 205 drives the rotating component 207 to rotate through the meshing part 206, the rotating component 207 drives the swing arm bracket 202 to rotate, the swing arm bracket 202 drives the mounting shell 303 to rotate, and the side brush 305 has two working states: the side brush 305 swings out and the side brush 305 retracts. When the side brush 305 swings out, it can greatly increase the cleaning coverage, improve the cleanliness of corners, reduce the number of repeated cleanings, and improve cleaning efficiency.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
