Detailed Implementation

[0019] like Figure 1 As shown, this utility model discloses a brush cleaning system for a curbstone robot, comprising: a frame 1, a first brush cleaning mechanism 2, a second brush cleaning mechanism 3, a multi-link telescopic mechanism 5, and a lifting mechanism 4. The frame 1 is arranged in an inverted L-shape, with a guide rail 6 at its horizontal end. A slider 7 is slidably mounted on the guide rail 6, and the slider 7 is driven by a cylinder 8. The first brush cleaning mechanism 2 is connected to the slider 7 via the lifting mechanism 4 for lifting and lowering. The second brush cleaning mechanism 3 is arranged perpendicular to the first brush cleaning mechanism 2, and is horizontally telescopically connected to the vertical end of the frame 1 via the multi-link telescopic mechanism 5.

[0020] like Figure 2 and Figure 3As shown, the lifting mechanism 4 includes: a movable support 41, a rack 42, a lifting guide rail 43, a lifting mechanism connector 44, a lifting slider 45, a lifting gear 46, and a lifting motor 47. The movable support 41 is connected to the slider 7. The rack 42 and the lifting guide rail 43 are mounted on the movable support 41. The lifting mechanism connector 44 is slidably connected to the lifting guide rail 43 through the lifting slider 45. The lifting motor 47 is mounted on the lifting mechanism connector 44. The lifting gear 46 meshes with the rack 42 and moves up and down along the rack 42 under the drive of the lifting motor 47.

[0021] The motion transmission process of the lifting mechanism 4 is as follows: the lifting motor 47 outputs rotational motion and drives the lifting gear 46 to rotate synchronously. The lifting gear 46, through its cooperation with the rack 42, combined with the guiding action of the slider 45 and the lifting guide rail 43, realizes the lifting mechanism connecting piece 44's lifting motion along the movable support 41. The lifting mechanism connecting piece 44 is connected to the first brush cleaning mechanism 2, thereby driving the first brush cleaning mechanism 2 to perform lifting motion.

[0022] like Figure 4 As shown, the multi-link telescopic mechanism 5 includes: a base 51, a lead screw 52, ​​a lead screw slider 53, a telescopic connecting rod 54, a lead screw motor 55, and a lifting end face 56. The base 51 is installed on the vertical end of the frame 1. The two ends of the lead screw 52 are rotatably connected to the base 51, and the lead screw slider 53 is slidably mounted on the lead screw 52. The telescopic connecting rod 54 consists of two connecting rods arranged in a scissor-like configuration. One end of the first connecting rod is connected to the lead screw slider 53, and the other end is connected to the lower end of the lifting end face 56. One end of the second connecting rod is connected to the lower end of the base 51, and the other end is connected to the upper end of the lifting end face 56. The lead screw motor 55 drives the lead screw 52 to rotate, causing the lead screw slider 53 to move up and down along the lead screw 52, ​​which in turn drives the lifting end face 56 to telescopically move via the telescopic connecting rod 54.

[0023] The motion transmission process of the multi-link telescopic mechanism 5 is as follows: the lead screw motor 55 outputs rotational motion and drives the lead screw 52 to rotate synchronously. The lead screw 52 drives the lead screw slider 53 to move up and down through the screw engagement transmission. The lead screw slider 53 converts its up and down motion into telescopic motion through the telescopic connecting rod 54. This telescopic motion is transmitted to the second brush cleaning mechanism 3 through the lifting end face 56, thereby realizing the telescopic motion of the second brush cleaning mechanism 3.

[0024] like Figure 1 , 2As shown in Figure 4, the first brush cleaning mechanism 2 and the second brush cleaning mechanism 3 have identical structures, both including: a disc brush assembly, a drive assembly, a crank-rocker assembly, a connecting rod assembly, and a cleaning mechanism frame. The first brush cleaning mechanism 2 includes a first disc brush assembly 21, a first drive assembly 22, a first crank-rocker assembly 23, a first connecting rod assembly 24, and a first cleaning mechanism frame 25. The second brush cleaning mechanism 3 includes a second disc brush assembly 31, a second drive assembly 32, a second crank-rocker assembly 33, a second connecting rod assembly 34, and a second cleaning mechanism frame 35.

[0025] like Figure 5 and 6 As shown, taking the first brush cleaning mechanism 2 as an example, the first disc brush assembly 21 includes a central disc brush 211 and four vibrating disc brushes 212. The first drive assembly 22 includes five brush cleaning motors 221 and corresponding motor mounts 222, with each of the five brush cleaning motors 221 driving its respective disc brush. The output shaft of each brush cleaning motor 221 is connected to its corresponding disc brush via a first crank-rocker assembly 23. The vibrating disc brushes 212 are connected to the central disc brush 211 and the first cleaning mechanism frame 25 via a first connecting rod assembly 24. The first cleaning mechanism frame 25 of the first brush cleaning mechanism 2 is connected to the lifting mechanism connector 44, and the cleaning mechanism frame of the second brush cleaning mechanism 3 is connected to the lifting end face 56 of the multi-link telescopic mechanism 5.

[0026] The first crank rocker assembly 23 includes a driving gear 231, a driven gear 232, a cleaning crank 233, and a disc brush 234. The output shaft of the brush cleaning motor 221 is connected to the driving gear 231. The driven gear 232 is rotatably connected to the motor base 222 via a rotating shaft and meshes with the driving gear 231. The eccentric shaft on the driven gear 232 is connected to one end of the cleaning crank 233. The other end of the cleaning crank 233 is connected to the top end of the disc brush 234. The bottom end of the disc brush 234 is connected to the center of the corresponding disc brush.

[0027] The motion transmission process of the first crank rocker assembly 23 is as follows: the brush cleaning motor 221 outputs rotational motion and drives the drive gear 231 to rotate synchronously. The drive gear 231 drives the driven gear 232 to rotate through meshing transmission. When the driven gear 232 rotates, it drives the cleaning crank 233 to perform planar motion. The cleaning crank 233 drives the disc brush 234 to perform reciprocating motion. The reciprocating motion of the disc brush 234 is further transmitted to the corresponding disc brush, so that the disc brush performs reciprocating motion synchronously, thereby realizing the high-frequency reciprocating motion function of the crank rocker assembly.

[0028] The first linkage assembly 24 includes four connecting rods 241, a central rotating seat 242, and four vibrating rotating seats 243. The central rotating seat 242 is fixed to the brush rod of the central disc brush, and the vibrating rotating seats 243 are respectively installed on the brush rods of the corresponding vibrating disc brushes. The two ends of the connecting rods 241 are hinged to the vibrating rotating seats 243 and the central rotating seat 242, respectively. One end of the first cleaning mechanism frame 25 is provided with a connecting seat, and the other end is provided with a connecting ring. The connecting rod 241 has a through hole in the middle, and the connecting ring passes through the through hole of the connecting rod 241. The connecting seat of the first brush cleaning mechanism 2 is connected to the lifting mechanism connecting piece 44, and the connecting seat of the second brush cleaning mechanism 3 is connected to the lifting end face 57 of the multi-link telescopic mechanism 5.

[0029] The first brush cleaning mechanism 2 of this utility model can realize the alternating up-and-down movement of the central disc brush 211 and the vibrating disc brush 212 through the above-described structure. The motion transmission process is as follows: When the central disc brush 211 moves downward, the disc brush rod 234 and the central rotating support 242 connected to it move downward synchronously with the central disc brush 211; when the central rotating support 242 moves downward, through the connecting rod 241 connected to it and with the help of the fulcrum of the connecting ring of the first cleaning mechanism frame 25, the downward movement of the central rotating support 242 is converted into the upward movement of the vibrating rotating support 243. When the vibrating rotating support 243 moves upward, the disc brush rod 234 and the vibrating disc brush 212 connected to it move downward synchronously, thereby realizing the alternating up-and-down movement of the central disc brush 211 and the vibrating disc brush 212.

[0030] In practice, an additional set of connecting rod assemblies with the same structure can be set below the first connecting rod assembly 24 as needed. The two ends of the connecting rod of this set of connecting rod assemblies are connected to the central rotating seat and the four vibrating rotating seats respectively, but no through hole is provided in the middle and it is not connected to the connecting ring of the first cleaning mechanism frame 25.

[0031] For complex terrains like curb stones, traditional roller brushes cannot fully adhere to the surface, resulting in incomplete cleaning. The linkage structure consisting of the central disc brush 211 and four vibrating disc brushes 212 is more suitable for handling flat or slightly uneven surfaces, especially in narrow spaces between curb stones where roller brushes have difficulty accessing. The disc brush design can form an all-round cleaning coverage.

[0032] The brush parts of the central disc brush 211 and the four vibrating disc brushes 212 are all made of wear-resistant synthetic fiber material. This effectively removes dirt without damaging the surface of the curbstone.

[0033] like Figure 7 As shown, the present invention provides a curbstone robot, which includes two sets of brush cleaning systems, wherein the brush cleaning system adopts the above-mentioned brush cleaning system for curbstone robots.

[0034] Two sets of brush cleaning systems are connected by aluminum profile connectors 14. A housing 15 is provided around the two sets of brush cleaning systems. A drive wheel 10 is located on one side of the housing 15, and a driven support wheel 11 is connected to the other side. The drive wheel 10 can be replaced with various sizes. The driven support wheel 11 includes a driven support wheel cylinder 12 and a driven support wheel hub 13. The driven support wheel cylinder 12 is connected to the driven support wheel hub 13, providing support when the curb robot is not working, thus enabling the curb robot to move smoothly on various road surfaces, while providing sufficient traction and maneuverability, and ensuring the machine stays close to the curb when working. A water spray mechanism 9 is provided on the aluminum profile connectors 14. The water spray mechanism 9 is used to rinse away residue after brush cleaning, ensuring the curb is thoroughly cleaned.

[0035] Working Principle: Based on the actual shape of the curbstone, the positions of the first brush cleaning mechanism 2 and the second brush cleaning mechanism 3 are adjusted using the lifting mechanism 4, the multi-link telescopic mechanism 5, and the cylinder 8, respectively. During the adjustment process, a crank-rocker assembly is used to convert the rotational motion of the brush cleaning motor into the linear or angular motion of the disc brush, achieving precise position adjustment. This ensures that the two sets of brush cleaning mechanisms can fully conform to the curbstone. During the cleaning process, the high-frequency reciprocating vibration of the disc brush thoroughly cleans the surface of the curbstone, effectively reducing damage to the curbstone while achieving complete cleaning.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the concept of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
