[0002] Elevators, as indispensable vertical transportation equipment in modern buildings, are widely used in residential, commercial, industrial, and public buildings, greatly improving the space utilization efficiency and the convenience of personnel movement. With the acceleration of urbanization and the increase in high-rise buildings, elevator technology is constantly innovating and developing to meet the growing demands for safety, comfort, efficiency, and intelligence. An elevator system mainly consists of a traction system, a guide system, a door system, a car system, a weight balancing system, an electric drive system, an electrical control system, and a safety protection system. Among these, the car system is the core component that directly carries passengers or goods, and its structural design directly affects the passenger experience and safety. The elevator car floor, as the bottom support structure of the car system, is not only the basic platform for passengers to stand or place items, but also bears the important responsibilities of connecting the car frame, bearing loads, transmitting power, and integrating various functional components.

[0003] Currently, elevator car bottoms mainly use reinforced ribs welded onto iron plates, which typically require painting. This type of elevator car bottom requires painting, and the reinforcing ribs are welded onto the iron plate, making the process complex, resulting in high production costs, and also high costs for subsequent replacement of damaged parts.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] This utility model discloses a galvanized steel elevator car bottom. The car bottom plane and the reinforcing ribs are detachably connected by fasteners. The car bottom plane and the reinforcing ribs can be manufactured separately and then assembled together by fasteners, which reduces welding, making the manufacturing process very convenient and the production cost low. Damaged parts can be replaced separately instead of replacing the whole car, and the replacement cost of damaged parts is low. The car bottom plane is made of galvanized steel plate, which eliminates the need for painting and grinding, reducing the number of processes and making it more environmentally friendly.
