Description

Technical Field

[0001] This invention relates to the field of elevators, specifically to an elevator car ventilation structure. Background Technology

[0002] As an enclosed space, the air quality inside an elevator car is crucial. National standards require ventilation openings at the top and bottom of the car, with specific requirements for the effective area of ​​these openings: the effective area of ​​ventilation openings at the top and bottom of the car should not be less than 1% of the car's effective area. The gaps around the car doors can be included in the calculation of the ventilation opening area, but should not exceed 50% of the required effective area.

[0003] Traditional elevator cars rely on gaps between the car walls and floor, and between the car walls and roof for ventilation. Increasing ventilation requires increasing these gaps, which are often visible to passengers and detract from the overall aesthetics. Furthermore, traditional elevators are equipped with specialized ventilation equipment (fans, air conditioners, etc.) to enhance ventilation, further increasing costs. Summary of the Invention

When the air volume is small, the air flows directly into the car from the hollow part of the ceiling assembly 5. When the air volume is large, part of the air enters the car through the ventilation hole 5022 of the first lamp holder plate and the ventilation hole 5023 of the second lamp holder plate, and part of the air flows into the car through the hollow part of the ceiling assembly 5.

[0068] Continue reading Figures 12-14In one embodiment of the present invention, the car wall assembly 2 includes four car wall modules spliced ​​end to end, namely a front car wall module 2a, a left car wall module 2b, a rear car wall module 2c, and a right car wall module 2d.

The folded edge structure includes a first folded edge 201 and a second folded edge 202 connected by fasteners. The fasteners include bolts and rivet nuts fixed to the folded edge structure. The rivet nuts are spaced between the first folded edge 201 and the second folded edge 202 and fixed to one of the folded edges. The bolt passes through the other folded edge and is connected to the rivet nut, so that when the first folded edge 201 and the second folded edge 202 are connected, a car wall ventilation opening 203 can be formed between them. The second folded edge 202 covers the car wall ventilation opening 203 by a bending structure.
