[0002] Elevator handrails are widely used in elevator cars, mainly for safety protection, support and fatigue relief, and some also serve as decoration.

[0003] Some elevator handrails are equipped with LED lights to enhance the decorative effect, but the brightness of these LED lights often cannot be adjusted.

[0004] In addition, as an enclosed space, the elevator car needs to pay attention to the internal air quality. The national standard requires that ventilation holes should be set on the upper and lower parts of the car, and there are clear requirements for the effective area of ​​the ventilation holes: the effective area of ​​the ventilation holes located on the upper and lower parts of the car should not be less than 1% of the effective area of ​​the car. The gaps around the car door can be included in the calculation of the ventilation hole area, but should not be greater than 50% of the required effective area. Traditional elevator cars are ventilated through the gaps between the car wall and the car bottom, and between the car wall and the car top. Increasing the ventilation volume requires increasing the gaps, and larger gaps are often visible to passengers, affecting the overall appearance. Summary of the invention

[0037] Continue reading Figure 5 In one embodiment of the present invention, the illuminant 300 is disposed on the lower side of the armrest mounting seat 200 and is also located on the outer side of the armrest body 201. The light shielding plate 302 is rotatably connected to the outer side of the armrest body 201 and is located lower than the position of the illuminant 300. The illuminant 300 is preferably an LED light strip, and the elastic member 301 is preferably a spring, which is disposed at both ends of the light shielding plate 302 and is connected between the armrest mounting seat 200 and the light shielding plate 302. In addition, the elastic member 301 can also adopt a torsion spring, a spring sheet, or other structures.

[0038] It should be noted that the term "inside" mentioned above refers to the side facing the inside of the elevator car, and "outside" refers to the side facing the hoistway.

[0039] The present invention also provides a method for adjusting the brightness of elevator car wall lighting, comprising: A vent 100 is provided on the car wall assembly 1. The handrail assembly 2 and the lighting assembly 3 as described above are installed inside the vent 100 of the car wall assembly 1. The lighting assembly 3 includes a light emitter 300, an elastic member 301 and a light shielding plate 302. The handrail assembly 2 covers the vent 100, the light emitter 300 illuminates the car wall assembly 1, and the light shielding plate 302 partially covers the light emitter 300. By controlling the elevator to move up and down, the airflow entering the vent 100 from the hoistway is increased. The airflow impacts the light shielding plate 302 and drives the light shielding plate 302 to rotate toward the side away from the light emitter 300, reducing the degree of covering the light shielding plate 302 on the light emitter 300, thereby increasing the degree of illumination of the car wall assembly 1 by the light emitter 300. By controlling the elevator to be stationary, the airflow entering the vent 100 from the hoistway is reduced, the degree of covering the light shielding plate 302 on the light emitter 300 is increased, thereby reducing the degree of illumination of the car wall assembly 1 by the light emitter 300.

[0040] Among them, when the elevator is stationary, the elastic member 301 is in a normal state, and the shading plate 302 is close to the light source 300, causing a large shielding to the light source 300, and the lighting brightness is low at this time. When the elevator is running, the airflow of the hoistway enters the vent 100 and impacts the shading plate 302, driving the shading plate 302 to rotate toward the side away from the light source 300, reducing the degree of covering the light source 300 by the shading plate 302, and the elastic member 301 is in a stretched state, and the lighting brightness is relatively large. When the elevator is stationary again, the elastic member 301 drives the shading plate 302 to reset in the direction close to the light source 300, and the lighting brightness returns to the original state. When the elevator accelerates, the amount of airflow entering the vent from the hoistway will further increase, causing the shading plate 302 to further rotate toward the side away from the light source 300, further reducing the degree of covering the light source 300 by the shading plate 302, and the lighting brightness will be enhanced at this time. When the elevator decelerates, the amount of air entering the vent from the hoistway will decrease, causing the shading plate 302 to rotate less towards the side away from the light source 300, thereby reducing the degree of covering of the light source 300 by the shading plate 302, and the lighting brightness will be weakened.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
