2. A hidden homing lifting device for a sweeping robot as claimed in claim 1, characterized in that: The middle part of the vertical frame (6) is a rectangular frame, and the upper and lower end surfaces of the vertical frame (6) are both provided with rectangular frames; the upper end surface of the vertical frame (6) is provided with a crossbeam and a support plate, and the crossbeam and the support plate are used to support the speed change mechanism (52) and the motor (53).

3. A hidden homing lifting device for a sweeping robot as claimed in claim 2, characterized in that: The vertical frame (6) and the bottom frame (2) are arranged vertically.

4. A hidden homing lifting device for a sweeping robot as claimed in claim 2, characterized in that: The vertical frame (6) is embedded in the wall or in the cabinet.

5. The hidden homing lifting device for a sweeping robot as claimed in claim 1, characterized in that: When the lifting platform (1) is at the upper limit position, the lifting platform (1) is hidden in the cabinet body or is covered by the cabinet board.

6. The hidden homing lifting device for a sweeping robot as claimed in claim 2, characterized in that: The bottom frame (2) is embedded in the ground, and a floating platform is arranged on the bottom frame (2); when the lifting platform (1) falls close to the bottom frame (2), the floating platform avoids the lifting platform (1), so that the lifting platform (1) and the ground are aligned, making it easy for the sweeping robot to enter the lifting platform (1); when the lifting platform (1) is lifted and leaves the bottom frame (2), the floating platform floats up, and the floating platform and the ground are aligned.

7. A hidden homing lifting device for a sweeping robot as claimed in claim 6, characterized in that: The floating platform is arranged on the bottom frame (2) via an elastic device and a limiting device.

8. The hidden homing lifting device for a sweeping robot as claimed in claim 1, characterized in that: The counterweight device (7) comprises at least three mass plates, and the mass plates are assembled and placed in a counterweight box.
