[0024] Reference Figure 1-5 The utility model embodiment provides a lift car structure, which includes a box body 1, a movable door 2 is arranged on the side of the box body 1, the lower surface of the movable door 2 and the bottom surface of the interior of the box body 1 are on the same plane, the left side surface of the interior of the box body 1 is fixedly connected to the handrail 4, the left side surface of the interior of the box body 1 is fixedly connected to the auxiliary inner selection plate 3, the auxiliary inner selection plate 3 is directly above the handrail 4, and a button is arranged on the inner side of the box body 1 near the movable door 2. The installation position of the auxiliary inner selection plate 3 is relatively low, which can ensure that the person in the wheelchair can press the internal button.

[0025] The auxiliary internal selection plate 3 includes a bottom plate 301, a baffle 302, a pull rope 303, a pull ring 304, a cover plate 305, a key slot 306, a slide slot 307, a limit plate 308, a protruding block 309, a fixed shaft 310, a pulley 311, and a roller 312. The bottom plate 301 is fixedly connected to the left inner surface of the box body 1, the slide slot 307 vertically passes through the bottom plate 301, the center of the front side surface of the bottom plate 301 is connected to the slide slot 307, the key slot 306 is arranged on the side surface of the slide slot 307 away from the inner surface of the box body 1, and a key is arranged inside the key slot 306.

[0026] The limiting plate 308 is fixedly connected to the side surface of the slide groove 307, the limiting plate 308 is L-shaped, there are two limiting plates 308 and they are symmetrical about the cover plate 305, the roller 312 is away from the cover plate 305 and contacts the side surface of the limiting plate 308, the pull rope 303 passes through the channel formed by the side surface of the slide groove 307 and the side surface of the limiting plate 308, the baffle 302 is fixedly connected to the side surface of the slide groove 307 near the bottom edge, and the horizontal position of the limiting plate 308 is close to the cover plate 305 to block the protruding block 309, thereby limiting the highest moving position of the cover plate 305.

[0027] The fixed shaft 310 is fixedly connected to the side surface of the slide groove 307. There are four fixed shafts 310 distributed at the four corners of the side surface of the slide groove 307. The cylindrical surface of the fixed shaft 310 is fixedly connected to the bearing, and the pulley 311 is fixedly connected to the outer cylindrical surface of the bearing.
