Technical Field

[0001] This utility model relates to the technical field of roller brush lifting devices for sweeping robots, specifically a roller brush lifting device. Background Technology

[0002] Currently, robotic vacuum cleaners are widely used for cleaning in homes and public places. Their roller brushes, as the core cleaning component, need to flexibly adjust their height to achieve optimal cleaning results when facing different floor conditions. Existing roller brush lifting devices, to meet the cleaning needs of complex floors, often employ complex mechanical structures such as multi-linkage and gear transmissions. This not only results in a large overall size and high assembly difficulty, but also increases the number of parts, raising production and assembly costs. Furthermore, the complex structure requires more maintenance and upkeep, further increasing operating costs. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a roller brush lifting device. Through the cooperation of a sliding frame and a bracket, the roller brush can be lifted at an angle. The overall structure is simple and clear, and the operation is convenient. At the same time, it is easy to assemble, reducing production and maintenance costs.

[0004] To achieve its technical objectives, this utility model adopts the following technical solution:

The sliding frame is slidably mounted inside the groove, and a through-hole is formed at the bottom. Mounting holes communicating with the through-hole are formed at both ends of the sliding frame. A baffle and a ramp integrally formed with the sliding frame are respectively provided on the left and right sides of the mounting holes. A support is movably mounted between the baffle and the ramp, and a roller is mounted on the end of the support near the ramp. The support is fixedly connected to the upper wall of the roller brush, and the support can move obliquely up and down along the ramp, thereby driving the roller brush to move obliquely up and down.

[0006] Preferably, the bracket is provided with a U-shaped groove with an opening facing downward at one end near the roller, and a roller is fitted in the U-shaped groove.

[0007] More preferably, the rollers are fitted onto the rollers near both ends.

[0008] More preferably, the U-shaped slot has two roller slots corresponding to the position of the roller.

[0009] Preferably, the bracket is fixedly connected to the connecting column and the upper wall of the roller brush by bolts.

[0010] More preferably, the bracket has a limiting hole, and the bolt is installed in the limiting hole.

[0011] More preferably, the lower end of the bolt passes through the limiting hole and is threaded to one end of the connecting column, and the other end of the connecting column is integrally formed with the upper wall of the roller brush.

[0012] Preferably, it also includes a driving component, which is kinetically connected to the sliding frame and can push the sliding frame to slide left and right along the slide groove.

[0013] More preferably, the drive component includes a rack disposed on the upper surface of the sliding frame and the two are integrated into a single design.

[0014] More preferably, the drive unit further includes a motor and a gear, the gear being sleeved on the end of the motor shaft, and the gear meshing with the rack.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention achieves the oblique lifting and lowering function of the roller brush simply and ingeniously by setting grooves and slots on the mounting plate, and combining them with structures such as sliding frame, baffle, roller ramp and support.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] A roller brush lifting device is mainly installed inside a robotic vacuum cleaner to assist in the lifting and lowering of its roller brush 4; such as Figure 1 and Figure 2 As shown, the assembly includes a mounting plate 1, a sliding frame 2, and a bracket 3. A roller brush 4 is mounted below the mounting plate 1, and a groove 5 is provided on the mounting plate 1. The sliding frame 2 is slidably mounted inside the groove 5, and a slot 6 is provided through the bottom. Mounting holes 7 are provided at the left and right ends of the sliding frame 2, communicating with the slot 6. A baffle 8 and a ramp 9 integrally formed with the sliding frame 2 are respectively provided on the left and right sides of the mounting holes 7. A bracket 3 is movably mounted between the baffle 8 and the ramp 9. A roller 12 is mounted on the end of the bracket 3 near the ramp 9. The bracket 3 is fixedly connected to the upper wall of the roller brush 4. The bracket 3 can be raised and lowered obliquely along the ramp 9, thereby driving the roller brush 4 to be raised and lowered obliquely.

[0030] As a preferred option, such as Figure 5As shown, the bracket 3 is provided with a U-shaped groove 10 with an opening facing downward at one end near the roller ramp 9. A roller 11 is installed in the U-shaped groove 10. Rollers 12 are fitted on the rollers 11 near both ends. The U-shaped groove 10 is provided with two roller slots 13 corresponding to the rollers 12. This design allows the bracket 3 to be assembled quickly and can better adapt to industrial production.

[0031] As a preferred option, such as Figure 1 , Figure 2 and Figure 6 As shown, the bracket 3 is fixedly connected to the connecting column 14 and the upper wall of the roller brush 4 by bolts; specifically, the bracket 3 has a limiting hole 15, and a bolt is installed in the limiting hole 15. The lower end of the bolt passes through the limiting hole 15 and is threaded to one end of the connecting column 14. The other end of the connecting column 14 is integrally formed with the upper wall of the roller brush 4. This design enables the bracket 3 and the roller brush 4 to move synchronously.

[0032] As a more preferred embodiment, the roller brush lifting device further includes a driving component, which is connected to the sliding frame 2 and can push the sliding frame 2 to slide left and right along the slide groove 5.

[0033] More preferably, the drive component includes a rack 16, which is disposed on the upper surface of the sliding frame 2 and the two are integrated into one piece.

[0034] As a preferred embodiment, the drive unit also includes a motor 17 and a gear 18. The gear 18 is sleeved on the end of the rotating shaft of the motor 17, and the gear 18 meshes with the rack 16. The rotation of the rotating shaft of the motor 17 drives the gear 18 to rotate, thereby causing the sliding frame 2 to move.

[0035] It should be noted that the bracket 3 and the sliding frame 2 are not fixed. The bracket 3 is installed (simply placed) between the baffle 8 and the ramp 9.

[0036] The operation method of this utility model is as follows:

[0037] Retraction and Storage: When the shaft of motor 17 rotates clockwise, the sliding frame 2 moves to the left under the action of rack 16 and gear 18. When the sliding frame 2 slides to the left and contacts the right end of the support 3 near the ramp 9, the ramp 9 of the sliding frame 2 will first push the support 3 to the left. During this process, due to the gravity of the brush 4, the support 3 will drive the brush 4 to move to the left, and the brush 4 will eventually retract into the outer shell. When the brush 4 reaches the preset retraction position, the sliding frame 2 continues to slide to the left. The support 3 overcomes the gravity of the brush 4, and the roller 12 of the support 3 will roll up to the right along the ramp 9, thereby driving the brush 4 to rise and lift, completing the storage of the entire brush 4.

[0038] Extended Use: When the roller brush 4 needs to be extended out of the housing for use, the motor 17 rotates counterclockwise, and the sliding frame 2 moves to the right under the action of the rack 16 and the gear 18. At this time, under the gravity of the roller brush 4, the roller 12 of the bracket 3 rolls down to the left along the rolling slope 9, thereby driving the roller brush 4 down; then the end of the bracket 3 near the baffle 8 (left end) will contact the baffle 8, and the baffle 8 will push the bracket 3 to the right, thereby driving the roller brush 4 to move to the right, and finally extending out of the housing.

[0039] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
