By integrating a lifting mechanism onto the straight beam on the side of the home elevator car, the problem of limited space in the home elevator shaft is solved, achieving safe and reliable elevator braking. This method is suitable for home elevator shafts with small top-floor space and large pit space.

AI Technical Summary
The lifting mechanism of home elevators is difficult to install in elevator shafts with limited space on the top floor and in the pit. Existing installation methods take up too much space and cannot effectively ensure elevator safety.
The lifting mechanism is integrated on the straight beam on the side of the car, with part of it located below the car. The vertical stroke of the lifting rope is greater than the maximum stroke of the car. The speed limiter maintains a safe distance from the lifting mechanism. The transmission component converts the lifting motion of the lifting rod into rotational motion, driving the wedge block of the safety clamp to clamp the guide rail and ensure safe braking.
It reduces the space occupied on the top floor and bottom of the elevator shaft, prevents the speed governor from loosening or disengaging when the car hits the top, and ensures that the safety brake is triggered immediately in case of overspeed, thereby improving the safety and installation flexibility of the elevator.

Abstract
Claims
1. A home lift, characterized in that The system includes a speed limiter (1) mounted on a guide rail (4), a car (2), and a lifting mechanism (3) mounted on a straight beam (21) on the side of the car (2). A lifting rope (11) is wound around the speed limiter (1), and the lifting rope (11) is connected to the lifting mechanism (3) to pull the lifting mechanism (3) vertically upward. Part of the lifting mechanism (3) is located below the side of the car (2), and the vertical travel of the lifting rope (11) is greater than the vertical travel of the car (2), so that when the car (2) is at its highest position, there is at least a safe distance between the speed limiter (1) and the lifting mechanism (3). The lifting mechanism (3) includes at least a vertically arranged and liftable lifting rod (31), a rotating component (32) rotatably mounted on the straight beam (21), and a transmission component (33) that drives the lifting rod (31) and the rotating component (32). The transmission component (33) is used to convert the lifting motion of the lifting rod (31) into the rotational motion of the rotating arm. When the speed limiter (1) is working, the lifting rod (31) is pulled up by the lifting rope (11) to drive the rotating component (32) to rotate. The rotation of the rotating component (32) is used to drive the wedge block (5) of the safety clamp to move.
2. A home lift according to claim 1, characterised in that One end of the transmission component (33) is hinged to the lifting rod (31), and the other end is hinged to the rotating component (32); the rotating component (32) is in a lower position relative to the transmission component (33).
3. A home lift according to claim 2, characterised in that An actuating element (35) is provided between the rotating element (32) and the wedge block (5) of the safety clamp. One end of the actuating element (35) is connected to the wedge block (5) of the safety clamp, and the other end is hinged to the rotating element (32). The rotating element (32) is in a low position relative to the wedge block (5) of the safety clamp.
4. A home lift according to claim 2, characterised in that, The bottom of the lifting rod (31) is provided with a connector (34), which is fixedly connected to the top of the transmission component (33).
5. A home lift according to claim 1, characterized in that The straight beam (21) is provided with a mounting seat (36), the mounting seat (36) is connected to the bottom of the straight beam (21), and the rotating part (32) is hinged to the mounting seat (36).
6. A home lift according to claim 1, characterized in that The lifting rod (31) is provided with an elastic element (38) for driving the lifting rod (31) to elastically reset.
7. A home lift according to claim 1, characterized in that, The straight beam (21) is provided with a guide seat (22), and the guide seat (22) is provided with a guide hole extending in the vertical direction. The lifting rod (31) passes through the guide hole.
8. A home lift according to claim 7, characterised in that A limiting member (37) is fixedly provided on the lifting rod (31). The limiting member (37) is located above the guide seat and abuts against the upper part of the guide seat to limit the initial position of the lifting rod (31) relative to the straight beam (21).
9. A home lift according to claim 8, characterised in that The limiting member (37) is threadedly connected to the lifting rod (31).
10. A home elevator according to claim 1, characterized in that The lifting rod (31) is provided with a connecting assembly for connecting the lifting rope (11), the connecting assembly comprises a first connecting plate (61) fixedly connected with the lifting rod (31), and a second connecting plate (62) connected with the first connecting plate (61) and used for fixing the lifting rope (11).
