Description

Technical Field

[0001] This utility model relates to the field of elevator light curtain technology, and more specifically to an elevator light curtain device. Background Technology

[0002] An elevator light curtain is a safety protection device for elevator doors made using the principle of photoelectric sensing. It is suitable for all elevators and protects the safety of passengers entering and exiting the elevator. An elevator light curtain consists of three main parts: an infrared transmitter and receiver installed on both sides of the elevator car door and a special flexible cable. Due to environmental protection and energy conservation needs, more and more elevators have eliminated the power supply box. Some brands of light curtains still have to use a power supply box due to their poor resistance to electromagnetic interference. However, with the popularization of the concept of green elevators, power supply box-free light curtains are a trend, because a lot of energy will inevitably be lost during the 220V to 24V conversion.

[0003] Insufficiency of existing technology: Existing light curtain equipment may misjudge or miss detection due to environmental interference factors such as dust, rain, strong light, and debris. The light curtain may misjudge external objects as obstacles, causing the elevator door to not close, or it may miss some small objects or people, causing danger when the door closes. Moreover, the reaction speed of the light curtain may have a certain delay, especially in environments with large changes in light, such as strong light or extremely dark environments. This delay may cause the elevator door to fail to identify passengers entering or leaving in time when closing, thus creating safety hazards. Utility Model Content

[0008] Furthermore, the bottom end of the second pressure plate is fixedly connected to the side of the elastic spring, and a wiping cloth is connected to the top end of the second pressure plate, the top end of the wiping cloth being connected to the side of the auxiliary mechanism.

[0009] Furthermore, the rotating mechanism includes a driving gear and a driven gear.

[0010] Furthermore, the auxiliary mechanism includes an outer fixing frame and a transparent protective plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by incorporating a cleaning mechanism, facilitates the regular removal of these contaminants, ensuring the normal operation of the light curtain sensor. When the surface of the light curtain sensor is covered with dirt, the infrared beam may be affected, causing the sensor to fail to accurately detect the presence of objects or people, resulting in misjudgments or missed detections. The cleaning mechanism can regularly remove accumulated dust, ensuring the surface of the light curtain is clean, thereby improving the recognition accuracy of the light curtain. Long-term accumulation of dirt may lead to corrosion or damage to the components of the light curtain sensor, shortening its service life. Regular cleaning can reduce these potential damages and extend the overall service life of the light curtain.

[0014] 2. This utility model, by incorporating a supplementary lighting mechanism, provides an additional light source, enhancing the stability and penetration of the infrared signal, enabling the light curtain system to operate normally in relatively dark environments. In situations of strong light, weak light, or significant lighting variations, the recognition accuracy of the light curtain may decrease, especially when the lighting is unstable, as the sensor may be affected by ambient light interference. The supplementary lighting mechanism, by providing necessary light, effectively reduces interference from external light sources, improving the stability of the light curtain system. The core function of an elevator light curtain is to prevent passengers or objects from being trapped by elevator doors. The supplementary lighting mechanism ensures that the light curtain sensor can still operate normally even in low-light conditions, thereby effectively reducing safety accidents caused by light curtain malfunctions or misjudgments.

The bottom end of the spring 201 is fixedly connected to the side of the rotating plate 106. A soft brush 203 is fixedly connected to the top end of the first pressure plate 202. The top end of the soft brush 203 is connected to the side of the auxiliary mechanism 4.

[0026] The bottom end of the second pressure plate 204 is fixedly connected to the side of the spring spring 201, and the top end of the second pressure plate 204 is connected to a wiping cloth 205, the top end of the wiping cloth 205 is connected to the side of the auxiliary mechanism 4.

[0027] The rotating mechanism 3 includes a driving gear 303 and a driven gear 304. A rotating rod 302 is fixedly connected to the side of the driving gear 303. A micro motor 301 is fixedly connected to the top of the rotating rod 302. The side of the micro motor 301 is fixedly connected to the top of the auxiliary mechanism 4. The side of the driving gear 303 meshes with the side of the driven gear 304. The inner side of the driven gear 304 is fixedly connected to the side of the support rod 105.

[0028] The auxiliary mechanism 4 includes an outer fixed frame 401 and a transparent protective plate 402.

[0030] The working principle of this utility model is as follows: When the elevator light curtain is running, the opening and closing of the elevator door is controlled by the cooperation between the infrared lamp 403 and the sensor plate. When the infrared lamp 403 is exposed to weak or strong light, its function will be affected. Therefore, supplementary light bulbs 404 are installed on both sides of the infrared lamp 403 to adjust the light intensity it receives, so that the infrared lamp 403 has a certain reaction time to extend its service life. In addition, dust or other impurities are easily attached to the surface of the infrared lamp 403, which may cause it to open or close accidentally during operation.

[0031] Therefore, a transparent protective plate 402 is placed on the outside of the infrared lamp 403. This not only keeps the surface of the infrared lamp 403 clean, but also allows for the cleaning of dust adhering to the surface of the transparent protective plate 402, thus ensuring the service life of the light curtain. The rotating plate 106 is controlled by the rotating motor 101 to move on the surface of the solenoid 102 and the auxiliary rod 103. A spring spring 201 and a first pressure plate 202 are installed on the side of the rotating plate 106. The elasticity of the spring spring 201 keeps the soft brush 203 on the side of the first pressure plate 202 in close contact with the side of the transparent protective plate 402. The movement of the rotating plate 106 drives it to clean the surface of the transparent protective plate 402. After the dust is cleaned, the water marks left on the surface of the transparent protective plate 402 also need to be cleaned.

[0032] Therefore, after the support rod 105 engages with the driven gear 304 and the driving gear 303, the micro motor 301 is started, and the rotating plate 106 is rotated. Then, the wiping cloth 205 on the surface of the second pressure plate 204 is pressed against the transparent protective plate 402 to clean the water marks, so as to ensure the smooth operation of the light curtain.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
