Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-11 An illuminated elevator handrail structure includes a handrail assembly 2 and an illumination assembly 3 installed inside a car wall assembly 1. A ventilation opening 100 is horizontally arranged on the car wall assembly 1, and the handrail assembly 2 blocks the ventilation opening 100. The illumination assembly 3 includes a light-emitting element 300, an elastic element 301, and a light-shielding plate 302. The light-emitting element 300 is disposed on the handrail assembly 2 to illuminate the car wall assembly 1. The light-shielding plate 302 is rotatably connected to the handrail assembly 2 and partially covers the light-emitting element 300. The light-shielding plate 302 is moved by the airflow entering through the ventilation opening 100, thereby changing the degree of coverage of the light-emitting element 300 by the light-shielding plate 302, and thus adjusting the degree of illumination of the car wall assembly 1 by the light-emitting element 300. The elastic element 301 is used to drive the light-shielding plate 302 to return to its original position.

[0030] Continue reading Figure 4 In one embodiment of the present invention, the handrail assembly 2 includes a handrail mounting base 200 and a handrail body 201. The handrail mounting base 200 is connected to the car wall assembly 1, and the handrail body 201 is connected to the handrail mounting base 200.

[0031] Further reading Figure 4 and Figure 11In one embodiment of this utility model, the upper and lower edges of the ventilation opening 100 are respectively provided with side plates 101. The handrail mounting base 200 is a long strip structure with an inner cavity communicating with the ventilation opening 100. The upper outer side of the handrail mounting base 200 has a vertically arranged first handrail mounting base connecting part 2001, which is connected to the portion of the car wall assembly 1 located above the ventilation opening 100 by fasteners. The lower part of the handrail mounting base 200 extends horizontally outward to form a second handrail mounting base connecting part 2002, which extends into the ventilation opening 100 of the car wall assembly 1 and is connected to the side plates 101 of the upper and lower edges of the ventilation opening 100 of the car wall assembly 1 by fasteners. Several air outlets 2000 corresponding to the light shield 302 are provided on the lower side of the inner cavity of the handrail mounting base 200. An opening communicating with the ventilation port 100 is formed between the first handrail mounting base connecting part 2001 and the second handrail mounting base connecting part 2002. The two ends of the handrail mounting base 200 are closed. Airflow enters the inner cavity of the handrail mounting base 200 through the opening and then exits only from the air outlet 2000. The structural design of the handrail mounting base 200 enables the airflow to be blown as much as possible toward the light shield 302.

[0032] Continue reading Figure 4 In one embodiment of this utility model, the car wall assembly 1 includes three upper and lower car wall modules 102, and a ventilation opening 100 is formed between adjacent car wall modules 102. The number and position of the handrail assemblies 2 correspond one-to-one with the ventilation openings 100. An air guide plate assembly 4 is provided on the outer side of the car wall assembly 1 at the position corresponding to the ventilation opening 100. The air guide plate assembly 4 guides the airflow of the shaft to the ventilation opening 100. The inner side of the air guide plate assembly 4 and the second handrail mounting base connecting part 2002 of the handrail mounting base 200 are connected to the side plates 101 of the upper and lower edges of the ventilation opening 100 of the car wall assembly 1 by fasteners. A gasket 402 is sandwiched between the side plates 101 of the upper and lower edges of the ventilation opening 100.

[0033] Further reading Figure 4 , Figure 9 , Figure 10In one embodiment of this utility model, the air guide plate assembly 4 includes an upper air guide plate 403 and a lower air guide plate 404 arranged vertically. The upper air guide plate 403 has an L-shaped structure, and the lower air guide plate 404 has an inverted L-shaped structure. An upper air guide channel 400 communicating with the ventilation opening 100 is formed between the upper air guide plate 403 and the outer side of the car wall assembly 1. A lower air guide channel 401 communicating with the ventilation opening 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 vertically by the ventilation opening 100. The upper air guide channel 400 and the lower air guide channel 401 are blocked by the lateral portions of the upper air guide plate 403 and the lower air guide plate 404, and the two are not directly connected. The horizontal portions on both sides of the upper air guide plate 403 and the lower air guide plate 404 extend inward and are inserted into the ventilation opening 100. A gasket 402 is provided on the horizontal extension portion of the upper air guide plate 403 and the lower air guide plate 404. The horizontal extension portion of the upper air guide plate 403 and the lower air guide plate 404, the gasket, and the second handrail mounting base connection portion 2002 are stacked and clamped between the side plates 101 on the upper and lower edges of the ventilation opening 100 by fasteners, so that the ventilation opening 100 is formed between the upper and lower car wall modules 102.

[0034] Continue reading Figure 4 In one embodiment of this utility model, the light-emitting element 300 is disposed on the lower side of the handrail mounting base 200 and also on the outer side of the handrail body 201. The light-shielding plate 302 is rotatably connected to the outer side of the handrail body 201, and its position is lower than that of the light-emitting element 300. The light-emitting element 300 is preferably an LED light strip, and the elastic element 301 is preferably a spring, which is disposed at both ends of the light-shielding plate 302 and connects the handrail mounting base 200 and the light-shielding plate 302. In addition, the elastic element 301 can also adopt a torsion spring, a spring sheet, or other structures.

[0035] It should be noted that the term "inner side" mentioned above refers to the side facing the inside of the elevator car, while "outer side" refers to the side facing the shaft.

[0036] The method for adjusting the lighting brightness of elevator car walls according to this utility model includes:

[0037] By controlling the elevator's vertical movement, the airflow entering the ventilation opening 100 in the shaft is increased. This airflow impacts the light-shielding plate 302, causing it to rotate away from the light-emitting element 300. This reduces the degree to which the light-shielding plate 302 obstructs the light-emitting element 300, thereby increasing the illumination of the car wall assembly 1 by the light-emitting element 300. Conversely, by controlling the elevator to stand still, the airflow entering the ventilation opening 100 in the shaft is reduced, increasing the degree to which the light-shielding plate 302 obstructs the light-emitting element 300, thus reducing the illumination of the car wall assembly 1 by the light-emitting element 300.

[0038] When the elevator is stationary, the elastic element 301 is in its normal state, and the light-shielding plate 302 is close to the light-emitting element 300, causing significant obstruction of the light-emitting element 300, resulting in low lighting brightness. When the elevator is running, the airflow in the shaft enters the ventilation opening 100 and impacts the light-shielding plate 302, causing it to rotate away from the light-emitting element 300, reducing the degree of obstruction. At this time, the elastic element 301 is in a stretched state, resulting in higher lighting brightness. When the elevator stops again, the elastic element 301 causes the light-shielding plate 302 to return to its original position, moving closer to the light-emitting element 300, and the lighting brightness returns to its original state. When the elevator accelerates, the airflow into the ventilation opening in the shaft further increases, causing the light-shielding plate 302 to rotate further away from the light-emitting element 300, further reducing the degree of obstruction, and thus increasing the lighting brightness. When the elevator decelerates, the airflow into the ventilation opening in the shaft decreases, causing the light shield 302 to rotate less to the side away from the light source 300, thereby reducing the degree of shading of the light source 300 by the light shield 302, and thus weakening the lighting brightness.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
