Description

Technical Field

[0001] The utility model belongs to the technical field of passenger elevators, and particularly relates to a passenger elevator car bottom structure. Background Art

[0002] The passenger elevator car bottom structure is an important part of the elevator car. Its main function is to support the bottom of the elevator car and ensure the safety of passengers and goods.

[0003] For example, a Chinese patent with publication number CN218465280U discloses an elevator car bottom structure, in which side beams are arranged at both ends of two brackets, and the cross-section of the side beams is ∟-shaped. Shock-absorbing pads are symmetrically fixedly installed at both ends of the two side beams, and car bottom plate side beams are fixedly installed on the shock-absorbing pads. The cross-section of the car bottom plate side beams is Z-shaped, and the top surface of the shock-absorbing pads is fixedly connected to the lower surface of the top extension surface of the car bottom plate side beams. Reinforcing ribs are also fixedly installed between the car bottom plate side beams. The reinforcing ribs are in an inverted "X" shape. The top surface of the reinforcing ribs is on the same horizontal plane as the top surface of the car bottom plate side beams, and the bottom of the reinforcing ribs is connected to the upper surface of the bottom extension surface of the car bottom plate side beams. A bottom plate is fixedly installed on the reinforcing ribs and the car bottom plate side beams, and a bending portion is vertically downwardly arranged at the right end of the bottom plate, and the bending portion is fixedly connected to the car door sill.

[0004] Although the above-mentioned public patent can effectively reduce the overall thickness and better adapt to the elevator shaft and pit space, there are still some defects that need to be improved. The bottom plate structure is a hollow structure with low strength, and there may be safety hazards such as deformation, cracking or even breakage, which will not only affect the normal operation of the elevator, but also pose a threat to the safety of passengers. In addition, the connection between the bottom plate and the side beam through anti-sway glue is not stable enough, and shaking or displacement occurs during the operation of the elevator, causing discomfort and safety hazards to passengers. In addition, when the bottom plate needs to be maintained or replaced, this connection method also brings troubles in disassembly, which increases the difficulty and time cost of maintenance work.
