The width direction of the bottom 40, i.e., the door opening direction of the door, the depth direction of the bottom 40, i.e., the direction from the elevator car door to the rear wall of the car opposite to the door, and the thickness direction of the bottom 40, i.e., the thickness direction of the bottom 40 itself.

Specifically, the support assembly 20 includes a first fixing member 22, a reinforcing member 21, and a second fixing member 23, one side of the first fixing member 22 is connected to the reinforcing member 21, and the other side is connected to the second fixing member 23, and has a sill 30 for connecting an elevator car; one side of the reinforcement member 21 is connected with the first fixing member 22, the other side is connected with the foot guard plate 10, and the reinforcement member 21 extends along the thickness direction of the car bottom 40 of the elevator car; one side of the second fixing element 23 is connected to the first fixing element 22 and the other side extends away from the first fixing element 22 for connection to the car bottom 40 of the elevator car.

In addition, the first fixing member 22 is formed by matching and assembling the first fixing plate 221, the bending plate 222 and the top plate 223, preferably, the first fixing plate 221 and the bending plate 222 are integrally formed, and the top plate 223 is independently processed after bending, so that the process difficulty is low.

Specifically, the top of the first fixing plate 221, the top of the bending plate 222 and the top plate 223 are connected by welding, so as to ensure the connection strength between the three, and reduce the welding cost. Of course, in other embodiments, the connection means such as bonding and riveting may be used. In addition, the first fixing member 22 may be directly integrally formed while being connected to the reinforcement member 21 and the sill 30, not limited to the combination of the above-described structures.

In this way, the relative position between the extension plate 232 and the car bottom 40 can be freely adjusted, so that the extension plate 232 can be conveniently connected to the car bottom 40 with different depths.

Further, at least one side of the extension plate 232 and the second fixing plate 231 has a second flange 233, and the second flange 233 can strengthen the bending resistance of the second fixing member 23, thereby improving the overall stability of the device.
