Description

Technical Field

[0001] This utility model relates to the field of elevators, specifically a ventilated elevator car top structure. Background Technology

[0002] In modern high-rise buildings, elevator cars serve as a frequently used vertical transportation vehicle, and the quality of their interior environment directly affects the user experience. Elevator cars are mainly composed of basic structures such as the car floor, car walls, and car roof.

[0003] Within the current realm of elevator technology, the ventilation system on the elevator car roof has revealed shortcomings. On one hand, its ventilation performance is generally unsatisfactory. During continuous elevator operation, especially during peak hours, a large number of passengers frequently enter and exit the car, significantly increasing the passenger density. At this time, the insufficient ventilation capacity of the car roof becomes prominent, hindering the influx of fresh air and resulting in stuffy and unpleasant air inside the car. On the other hand, existing elevator car roof ventilation systems lack flexible adjustment mechanisms. Passengers' needs for air circulation vary with the seasons. For example, in the hot summer, people crave stronger ventilation to cool down, while in the cold winter, excessive ventilation can lead to excessively low temperatures inside the car, causing discomfort. However, because the ventilation effect cannot be effectively adjusted according to actual needs, it is difficult to meet passengers' expectations for a comfortable riding experience in different environments.

[0004] Based on the above issues, the applicant proposes a ventilated elevator car top structure. Utility Model Content

[0005] The purpose of this invention is to provide a ventilated elevator car top structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ventilated elevator car top structure includes a car top assembly, which includes a car top plate and a ventilation adjustment plate. The car top plate is provided with a plurality of car top ventilation holes. The ventilation adjustment plate is disposed on the car top plate and covers the car top ventilation holes. The ventilation adjustment plate is provided with a plurality of adjustable ventilation holes corresponding to the positions of the car top ventilation holes. The ventilation adjustment plate can adjust its position on the car top plate to change the overlap area between the car top ventilation holes and the adjustable ventilation holes, thereby changing the ventilation effect of the elevator car top structure.

[0008] Furthermore, both the ventilation holes on the car roof and the adjustable ventilation holes are oblong-shaped holes.

[0009] Furthermore, the ventilation adjustment plate is connected to the ventilation hole on the car roof via an adjustment bolt, and the position of the ventilation adjustment plate on the car roof can be adjusted by loosening the adjustment bolt.

[0010] Furthermore, at least one of the front, rear, left, and right sides of the car roof panel is provided with a number of car roof ventilation holes and ventilation adjustment plates.

The ceiling assembly is a hollow annular structure, which includes a rear frame, a front frame disposed opposite to the rear frame, and two lamp holder plates respectively connected between the rear frame and the front frame. The two lamp holder plates are located on the left and right sides of the rear frame.

[0012] Furthermore, there is a gap between the lamp holder plate and the car roof plate.

[0013] Furthermore, the lamp holder plate includes a horizontal section and an inclined section connected to the horizontal section. The horizontal section is closer to the center of the ceiling assembly, and the inclined section faces away from the center of the ceiling assembly. The horizontal section has a plurality of first lamp holder plate ventilation holes, and the inclined section has a plurality of second lamp holder plate ventilation holes. The second lamp holder plate ventilation holes face the adjacent car wall. The first and second lamp holder plate ventilation holes correspond to the lamps in the ceiling assembly and are able to transmit light into the car.

[0014] Furthermore, it also includes a guardrail assembly installed on the upper part of the car roof assembly.

[0015] Furthermore, a protective cover is provided on the guardrail assembly, which covers the ventilation holes on the car roof and has filter holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) This utility model provides car roof ventilation holes on the car roof panel, which improves the ventilation volume of the car roof. At the same time, it provides a ventilation adjustment plate, which can adjust the ventilation effect of the car roof assembly as needed.

[0018] 2) This utility model provides a first lamp holder plate ventilation hole and a second lamp holder plate ventilation hole on the ceiling. The first lamp holder plate ventilation hole and the second lamp holder plate ventilation hole can both provide ventilation and serve as a light-transmitting decorative function.

[0019] 3) This utility model has a protective cover with filter holes on the guardrail assembly, which can prevent dust and other debris from entering the car, and ensure the cleanliness and hygiene of the car while providing ventilation. Attached Figure Description
