Description

Technical Field

[0001] The present invention relates to the field of elevators, and in particular to an elevator car ventilation and lighting handrail device and an elevator car wall lighting brightness adjustment implementation method. Background Art

[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 is often unable to be adjusted.

[0004] Furthermore, as a confined space, elevator cabins require attention to internal air quality. National standards require ventilation holes in the upper and lower sections of the cabin, with clear requirements for their effective area: the effective area of each vent located above and below the cabin should not be less than 1% of the cabin's effective area. The gaps around the cabin door can be included in the calculation of the ventilation area, but should not exceed 50% of the required effective area. Traditional elevator cabins are ventilated through the gaps between the cabin wall and the floor, and between the cabin wall and the ceiling. Increasing ventilation requires increasing these gaps, and larger gaps are often visible to passengers, affecting the overall aesthetics. Summary of the Invention

[0005] The object of the present invention is to provide an elevator car ventilation lighting handrail device and an elevator car wall lighting brightness adjustment method to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A ventilation and lighting handrail device for an elevator car comprises a car wall assembly, a handrail assembly and a lighting assembly, wherein a ventilation opening is provided on the car wall assembly, the handrail assembly is provided on the inner side of the car wall assembly and blocks the ventilation opening, the lighting assembly comprises a light-emitting body, an elastic member and a sunshade, the light-emitting body is provided on the handrail assembly to illuminate the car wall assembly, the sunshade is movably connected to the handrail assembly and / or the car wall assembly and partially covers the light-emitting body, the sunshade is moved by the impact of the airflow entering from the ventilation opening, thereby changing the degree of coverage of the light-emitting body by the sunshade, and further adjusting the degree of illumination of the car wall assembly by the light-emitting body, and the elastic member is used to drive the sunshade to reset.

[0008] Furthermore, the handrail assembly includes a handrail mounting seat and a handrail body, the handrail mounting seat is connected to the car wall assembly, and the handrail body is connected to the handrail mounting seat.

[0009] Furthermore, the upper and lower edges of the vent are respectively provided with side panels, the upper side of the armrest mounting seat is connected to the part of the car wall assembly located on the upper side of the vent by fasteners, and the lower side of the armrest mounting seat is connected to the side panels of the upper and lower edges of the vent of the car wall assembly by fasteners.

[0010] Furthermore, the armrest mounting seat has an inner cavity connected to the ventilation port, and an air outlet corresponding to the sunshade is provided on the lower side of the inner cavity.

[0011] Furthermore, the car wall assembly includes at least two upper and lower car wall modules, and a ventilation opening is formed between adjacent car wall modules. An air guide plate assembly is provided on the outer side of the car wall assembly at a position corresponding to the ventilation opening. The air guide plate assembly guides the airflow in the shaft to the ventilation opening. The inner side of the air guide plate assembly and the lower outer side of the handrail mounting seat are connected between the side plates of the upper and lower edges of the ventilation opening of the car wall assembly through fasteners, and a gasket is sandwiched between the side plates of the upper and lower edges of the ventilation opening.

[0012] Furthermore, the light emitting body and the sunshade are both arranged on the lower side of the armrest mounting seat and are also located on the outside of the armrest body. The position of the sunshade is lower than that of the light emitting body, and the elastic member is connected between the armrest mounting seat and the sunshade.

[0013] Furthermore, an air guide plate assembly is provided on the outer side of the car wall assembly at a position corresponding to the vent, and the air guide plate assembly guides the airflow in the hoistway to the vent.

[0014] Furthermore, an upper air guide channel and a lower air guide channel connected to the ventilation port are formed between the air guide plate assembly and the outer side of the car wall assembly. The upper air guide channel and the lower air guide channel are separated up and down by the ventilation port, and the upper air guide channel and the lower air guide channel are not directly connected.

The handrail mounting seat 200 is connected to the car wall assembly 1 , and the handrail body 201 is connected to the handrail mounting seat 200 .

[0048] Further reading Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 12 In one embodiment of the present invention, the upper and lower edges of the vent 100 are each provided with side panels 101. The handrail mounting base 200 is an elongated structure having an inner cavity communicating with the vent 100.

The structural design of the armrest mounting seat 200 can make the airflow blow toward the sun visor 302 as much as possible.

[0049] Continue reading Figure 5 、 Figure 10 、 Figure 11In one embodiment of the present invention, the car wall assembly 1 includes three upper and lower car wall modules 102, and vents 100 are formed between adjacent car wall modules 102.

A gasket 402 is sandwiched between the side plates 101 at the upper and lower edges of the vent 100.

[0050] Further reading Figure 5 、 Figure 10 、 Figure 11 In one embodiment of the present invention, the air guide plate assembly 4 includes an upper air guide plate 403 and a lower air guide plate 404 arranged up and down, the upper air guide plate 403 is an L-shaped structure, and the lower air guide plate 404 is an inverted L-shaped structure. An upper air guide channel 400 connected to the vent 100 is formed between the upper air guide plate 403 and the outer side of the car wall assembly 1, and a lower air guide channel 401 connected to the vent 100 is formed between the lower air guide plate 404 and the outer side of the car wall assembly 1. The upper air guide channel 400 and the lower air guide channel 401 are separated up and down by the vent 100. The upper air guide channel 400 and the lower air guide channel 401 are blocked by the lateral parts of the upper air guide plate 403 and the lower air guide plate 404, and the two are not directly connected. The lateral parts on both sides of the upper air guide plate 403 and the lower air guide plate 404 extend inward and are inserted into the vent 100. Gaskets 402 are set on the lateral extension parts of the upper air guide plate 403 and the lower air guide plate 404. The lateral extension parts of the upper air guide plate 403 and the lower air guide plate 404, the gaskets, and the second handrail mounting seat connection part 2002 are overlapped and clamped between the side panels 101 at the upper and lower edges of the vent 100 by fasteners, so that the vent 100 is formed between the upper and lower car wall modules 102.

[0051] Continue reading Figure 5 In one embodiment of the present invention, the illuminator 300 is disposed below the armrest mounting base 200 and also outside the armrest body 201. The light shield 302 is pivotally connected to the outside of the armrest body 201 and positioned below the illuminator 300. The illuminator 300 is preferably an LED light strip, and the elastic member 301 is preferably a spring, disposed at both ends of the light shield 302 and connected between the armrest mounting base 200 and the light shield 302. Alternatively, the elastic member 301 may be a torsion spring, a spring, or other similar structure.

[0052] It should be noted that the term "inside" mentioned above refers to the side facing the interior of the elevator car, and "outside" refers to the side facing the hoistway.

[0053] The present invention also provides a method for adjusting the brightness of elevator car wall lighting, comprising:

[0054] A vent 100 is formed in the car wall assembly 1. The handrail assembly 2 and lighting assembly 3, as described above, are mounted inside the vent 100 of the car wall assembly 1. The lighting assembly 3 comprises a light-emitting element 300, an elastic member 301, and a light shield 302. The handrail assembly 2 covers the vent 100, while the light-emitting element 300 illuminates the car wall assembly 1. The light shield 302 partially shields the light-emitting element 300. By controlling the elevator to move up and down, airflow from the hoistway into the vent 100 is increased. This airflow impacts the light shield 302, causing it to rotate away from the light-emitting element 300, reducing the coverage of the light shield 302 on the light-emitting element 300 and thereby increasing the illumination of the car wall assembly 1 by the light shield 300. By controlling the elevator to stop, airflow from the hoistway into the vent 100 is reduced, increasing the coverage of the light shield 302 on the light-emitting element 300 and thereby reducing the illumination of the car wall assembly 1 by the light shield 300.

[0055] When the elevator is stationary, the elastic member 301 is in its normal state, and the light shield 302 is close to the light source 300, significantly obstructing the light source 300. At this point, the lighting brightness is low. When the elevator is in operation, airflow from the hoistway enters the vent 100 and impacts the light shield 302, causing the light shield 302 to rotate away from the light source 300, reducing the degree of coverage of the light source 300 by the light shield 302. At this point, the elastic member 301 is in a stretched state, and the lighting brightness is high. When the elevator stops again, the elastic member 301 forces the light shield 302 to return toward the light source 300, restoring the lighting brightness to its original state. When the elevator accelerates, the amount of airflow from the hoistway entering the vent further increases, causing the light shield 302 to rotate further away from the light source 300, further reducing the degree of coverage of the light shield 302 by the light shield 302. At this point, the lighting brightness increases. When the elevator decelerates, the amount of air entering the vent from the shaft will decrease, causing the shading plate 302 to rotate less toward the side away from the light source 300, thereby reducing the degree of coverage of the light source 300 by the shading plate 302, and the lighting brightness will be weakened.

[0056] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
