[0032] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in conjunction with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed according to the specific implementation situation by adding or reducing connection accessories. Each technical feature in the present utility model can be combined interactively without conflicting with each other, referring to Figure 1-8 .

[0033] A side sweeping module for a floor sweeper with telescopic bristles, comprising a gear box 1. Inside the gear box 1, there are a driving motor 2, a first rotating shaft 31, a second rotating shaft 32, a third rotating shaft 33, a rotating sleeve 5 and a damping shaft 7. An output gear 21 is provided on the output shaft of the driving motor 2. A first rotating gear 41 and a second rotating gear 42 are provided on the first rotating shaft 31. A third rotating gear 43 and a fourth rotating gear 44 are provided on the second rotating shaft 32. A fifth rotating gear 45 is provided on the third rotating shaft 33. A sixth rotating gear 46 is provided on the rotating sleeve 5. The output gear 21 meshes with the first rotating gear 41. The second rotating gear 42 meshes with the third rotating gear 43. The fourth rotating gear 44 meshes with the fifth rotating gear 45. The fifth rotating gear 45 meshes with the sixth rotating gear 46. Inside the rotating sleeve 5, there is a lifting sleeve 6. The lower end of the lifting sleeve 6 extends outside the gear box 1 and is provided with a bristle mounting cylinder 9. The bristle mounting cylinder 9 is provided with circumferentially distributed bristles 91. The inner wall of the rotating sleeve 5 is provided with internal threads 51. The outer wall of the lifting sleeve 6 is provided with external threads 61 adapted to the internal threads 51. The damping shaft 7 extends into the lifting sleeve 6 and a damping rubber ring (not shown in the figure) is provided between the damping shaft 7 and the inner wall of the lifting sleeve 6. The bottom of the gear box 1 is provided with a receiving sleeve 8. The receiving sleeve 8 is provided with a bristle contraction notch 81.

[0034] During specific applications, when the floor sweeper starts working and needs to use the side sweeping module to sweep the corners, the drive motor 2 starts working. The drive motor 2 drives the output gear 21 to rotate. The output gear 21 drives the first rotating gear 41 to rotate. The first rotating gear 41 drives the second rotating gear 42 to rotate. The second rotating gear 42 drives the third rotating gear 43 to rotate. The third rotating gear 43 drives the fourth rotating gear 44 to rotate. The fourth rotating gear 44 drives the fifth rotating gear 45 to rotate. The fifth rotating gear 45 drives the sixth rotating gear 46 to rotate. The sixth rotating gear 46 drives the rotating sleeve 5 to rotate. Since the damping shaft 7 forms a damping contact with the lifting sleeve 6 through a damping rubber ring, when the rotating sleeve 5 rotates, due to the damping effect of the damping rubber ring on the lifting sleeve 6, the lifting sleeve 6 will not rotate synchronously with the rotating sleeve 5. At this time, since the rotating sleeve 5 and the lifting sleeve 6 are threadedly connected through the internal thread 51 and the external thread 61, the threaded connection structure formed by the external thread 61 and the internal thread 51 can drive the lifting sleeve 6 to descend, so that the brush mounting sleeve 9 and the brush 91 extend downward from the storage sleeve 8 and start the floor sweeping work. When it is necessary to store the brush 91, the above process can be reversed to retract the brush mounting sleeve 9 and the brush 91 upward. During the upward storage process of the brush 91, since the brush contraction notch 81 is provided on the storage sleeve 8, the brush 91 can be smoothly stored inside the storage sleeve 8 through the brush contraction notch 81.

[0035] In this embodiment, the brush contraction notch 81 is provided at the bottom of the storage sleeve 8. The brush contraction notch 81 forms a guiding inclined surface 811 and a storage arc surface 812 at the bottom of the storage sleeve 8. On the one hand, through the guiding inclined surface 811 and the storage arc surface 812, the brush 91 can be stored more smoothly, avoiding the situation of storage jamming and making the storage smoother; on the other hand, through the guiding inclined surface 811 and the storage arc surface 812, the brush 91 can also be protected to avoid damage to the brush 91.

[0036] In some embodiments, the damping shaft 7 is fixedly installed in the gearbox 1. An annular recess 71 is provided at the lower end of the damping shaft 7 extending into the inner wall of the lifting sleeve 6. The damping rubber ring is arranged at the annular recess 71. The outer wall of the damping rubber ring is frictionally connected with the inner wall of the lifting sleeve 6. The damping shaft 7 can be fixedly connected to the gearbox 1 through screws. The gearbox is provided with a damping shaft installation groove. The inside of the damping shaft installation groove has a flat position. The damping shaft is provided with a matching installation flat position, so as to realize the radial fixed installation through the flat position.

[0037] In some embodiments, a first limiting block 52 is provided on the inner wall of the rotating sleeve 5, and a second limiting block 62 that cooperates with the first limiting block 52 is provided on the outer wall of the lifting sleeve 6. When the lifting sleeve 6 descends to the lowest point, the first limiting block 52 and the second limiting block 62 limit each other to restrict the relative rotation between the rotating sleeve 5 and the lifting sleeve 6.

[0038] In specific applications, after the lifting sleeve 6 descends to a preset position, the relative rotation between the lifting sleeve 6 and the rotating sleeve 5 is restricted by the first limiting block 52 and the second limiting block 62. At this time, the lifting sleeve 6 descends to the lowest point, and the driving motor 2 continues to drive the rotating sleeve 5 to rotate. The rotating sleeve 5 drives the lifting sleeve 6 to rotate synchronously through the structure of the first limiting block 52 and the second limiting block 62, and the lifting sleeve 6 drives the brush mounting sleeve 9 and the brush 91 to rotate synchronously to achieve the floor sweeping function. In this state, the lifting sleeve 6 rotates against the damping force of the damping rubber ring. In this technical solution, the lifting and floor sweeping of the brush 91 can be achieved by one driving motor 2, saving components, simplifying the structure, and reducing the implementation cost.

[0039] In some embodiments, both the output gear 21 and the first rotating gear 41 are helical gears; helical gears have better torque transmission performance and less noise.

[0040] In some embodiments, the first rotating gear 41 and the second rotating gear 42 together form a first double gear, and the third rotating gear 43 and the fourth rotating gear 44 together form a second double gear; the sixth rotating gear 46 and the rotating sleeve 5 are integrally formed components.

[0041] In some embodiments, the receiving sleeve 8 is provided with a receiving stepped position 83 on the inner wall of its lower part where the brush contraction notch 81 is opened, and the receiving stepped position 83 is used to receive the brush 91. When the brush 91 is in the received state, the head of the brush 91 close to the brush mounting sleeve 9 is received in the receiving stepped position 83.

[0042] In some embodiments, the lifting sleeve 6 includes an external thread portion 601 and a connecting portion 602. The external thread 61 is provided on the inner wall of the external thread portion 601. The lower end of the damping shaft 7 extends into the inner cavity of the external thread portion 601, and the connecting portion 602 extends through from the lower end of the rotating sleeve 5 and is fixedly connected to the brush mounting cylinder 9.

[0043] In some embodiments, the gearbox 1 includes a lower housing 11 and an upper housing 12, and the receiving sleeve 8 and the lower housing 11 are integrally formed; a housing connection clip 111 is provided on the side wall of the lower housing 11, and a housing connection buckle 121 that cooperates with the housing connection clip 111 is provided on the side wall of the upper housing 12. The housing connection buckle 121 is buckled at the housing connection clip 111 to fixedly connect the upper housing 12 and the lower housing 11. By providing the housing connection clip 111 and the housing connection buckle 121, the quick assembly of the upper housing 12 and the lower housing 11 can be realized, and the production efficiency can be improved.

[0044] In some embodiments, a rotating sleeve mounting hole 101 for the rotating sleeve 5 to pass through is formed in the gearbox 1. The lower end of the rotating sleeve 5 passes through the rotating sleeve mounting hole 101 and extends to the bottom of the gearbox 1. A rotating sleeve limiting ring 102 is provided inside the gearbox 1 near the rotating sleeve mounting hole 101. A limiting step 53 that cooperates with the rotating sleeve limiting ring 102 is provided on the outer wall of the rotating sleeve 5. The limiting step 53 is cooperatively and limitedly mounted at the rotating sleeve limiting ring 102. A rotating sleeve limiting sleeve 103 is provided on the upper inner wall of the gearbox 1. The upper end of the rotating sleeve 5 extends into the rotating sleeve limiting sleeve 103. The rotational mounting of the rotating sleeve 5 is realized through the rotating sleeve mounting hole 101, the rotating sleeve limiting ring 102, and the rotating sleeve limiting sleeve 103.
