Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator technology, specifically to an elevator escape car with emergency lighting linkage. Background Technology
[0002] With the continuous development of elevator technology, the safety and reliability of elevators, as an indispensable vertical transportation tool in modern buildings, remain a focus of attention. Especially in emergencies such as fires and earthquakes, the ability of the elevator car to provide effective escape for trapped personnel has become a crucial indicator of elevator performance.
[0003] Existing elevator lighting designs primarily focus on the interior of the elevator car, aiming to provide passengers with a suitable lighting environment during normal travel. Through reasonable lamp layout and brightness adjustment, these designs can, to a certain extent, meet passengers' basic needs for viewing floor displays, operating buttons, and observing the interior environment. However, this car-centric lighting design proves inadequate in emergency escape situations. When an elevator encounters an emergency and people are trapped inside, needing to escape through the safety doors, while the interior lighting can illuminate the space and help them locate the safety doors, it is ineffective for illuminating the external escape routes. After opening the safety doors, trapped passengers often face a dimly lit or even completely dark environment, making it difficult for them to quickly and accurately assess the external escape routes, such as the presence of obstacles or whether the escape direction is correct. In such situations, trapped passengers are highly susceptible to collisions, falls, and other accidents due to poor visibility, which not only delays escape time but may also lead to injuries, further increasing the difficulty and danger of escape. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an elevator escape cabin with emergency lighting linkage, solving the problems mentioned in the background art.
[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows: An elevator escape car with emergency lighting linkage, including a car and a door panel installed on the car; A connecting plate is installed on the door panel, a drive wheel is rotatably installed on the car, a synchronous belt is driven on the drive wheel, the door panel is connected to the synchronous belt through the connecting plate, and the two door panels are respectively connected and fixed to the synchronous belts on the upper and lower sides of the drive wheel; The car is equipped with a top plate, a safety door is mounted on the top plate, first lights are mounted on both sides of the safety door on the top plate, support plates are mounted on both sides of the safety door on the top plate, second lights are mounted on the support plates, a cam is mounted on the pivot of the safety door, and a push switch is mounted on one side of the safety door on the top plate. The second lights are connected to an external power source through the push switch.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, pulleys are rotatably mounted on the connecting plate, guide rails are mounted on the car, and the door panel slides at the upper limit of the car via the pulleys and guide rails.
[0008] The beneficial effects of adopting the above-mentioned further solutions are: This structure makes the door panel move more smoothly and steadily, reducing friction and resistance during movement and lowering the probability of malfunctions such as jamming or shaking. Simultaneously, the limit-sliding design ensures the door panel always moves along the predetermined trajectory, preventing deviation or derailment. This improves the accuracy and reliability of door opening and closing, ensuring the door can open or close quickly and stably in emergencies, providing a safety net for occupants to escape. Furthermore, the structure is simple and compact, occupying little space and minimizing its use within the car, thus promoting efficient use of the interior space.
[0009] Furthermore, when the safety door is opened, the cam rotates with the safety door and triggers a push-button switch, and the second lighting lamp is connected to an external power source through the push-button switch.
[0010] The beneficial effects of adopting the above-mentioned further solutions are: The system achieves linkage between the secondary lighting and the opening of the safety door. In an emergency, when personnel open the safety door, a cam rotates with the door, triggering a push-button switch, and the secondary lighting immediately illuminates without requiring manual intervention, ensuring timely illumination. This illuminates the external escape route for personnel exiting the elevator car, allowing them to quickly see their surroundings and avoid dangers such as collisions and falls due to insufficient light, greatly improving the safety and efficiency of the escape and buying valuable escape time.
[0011] Furthermore, ventilation openings are provided on the top plate.
[0012] The beneficial effects of adopting the above-mentioned further solutions are: Ventilation vents ensure air circulation within the elevator car. During normal elevator operation, vents prevent the accumulation of stale air and odors, providing passengers with a comfortable environment. In emergencies, when people are trapped inside, vents prevent oxygen deprivation, maintaining normal breathing and protecting their lives. This prevents discomfort or even death caused by oxygen deficiency, allowing passengers to remain alert and in good physical condition for escape or while awaiting rescue.
[0013] Furthermore, the first and second lights are each provided in two sets, and the two sets of first and second lights are symmetrically distributed on both sides of the safety door.
[0014] The beneficial effects of adopting the above-mentioned further solutions are: The symmetrically distributed design of multiple sets of lights increases the illumination range and brightness. Inside the elevator car, two sets of primary lights evenly illuminate every corner, ensuring sufficient lighting for personnel regardless of their location, facilitating various operations such as locating escape tools and assessing the surrounding environment. Outside the car, two sets of secondary lights are symmetrically distributed on either side of the safety doors, providing escapers with a clear and comprehensive view, illuminating all directions of the external escape route, reducing blind spots, and enabling them to accurately assess their surroundings, avoiding misdirection or accidents due to insufficient light, thus improving the safety and success rate of escape.
[0015] Furthermore, a motor is installed at the top of the car, and the transmission wheel is driven by the motor. When the transmission wheel rotates, it drives the two door panels to move in opposite directions through a synchronous belt and a connecting plate.
[0016] The beneficial effects of adopting the above-mentioned further solutions are: The motor drives the transmission wheel to rotate, which in turn moves the door panel via a synchronous belt and connecting plate. This transmission method offers advantages such as smooth transmission, accurate transmission ratio, and high efficiency. The motor provides stable and powerful force, ensuring the door panel can open and close quickly and smoothly. The synchronous belt drive precisely controls the door panel's movement distance and speed, avoiding problems such as incomplete opening and closing or uneven speed caused by transmission errors. In emergencies, rapid and accurate door opening and closing can buy time for personnel to escape, improving escape efficiency. Furthermore, this transmission method has a simple structure, is easy to maintain, and reduces equipment failure rate and maintenance costs.
[0017] This utility model provides an elevator escape car with emergency lighting linkage. It has the following beneficial effects: The primary lighting inside the elevator car provides ample and even illumination. During normal elevator operation, it facilitates passenger movement; in emergencies, when people are trapped inside awaiting rescue or preparing for initial escape, the primary lighting ensures clear visibility, allowing them to accurately locate escape tools and assess their surroundings, preventing collisions, trampling, and other dangers caused by insufficient light.
[0018] The second lighting fixture located outside the car is activated via a linkage mechanism between a cam on the safety door hinge and a push-button switch on the ceiling. When the safety door is opened, the cam rotates with the door, triggering the push-button switch, and the second lighting fixture illuminates instantly. In an emergency escape, the environment outside the car may be relatively dark. The timely activation of the second lighting fixture illuminates the external escape route for people exiting the car, helping them see surrounding obstacles, stairwell locations, etc., ensuring a safe and smooth escape.

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.
[0023] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows: Example 1: An elevator escape car with emergency lighting linkage includes a car 2, a door panel 1 installed on the car 2, a connecting plate 101 installed on the door panel 1, a drive wheel 104 rotatably installed on the car 2, and a synchronous belt 105 driven on the drive wheel 104. The door panel 1 is connected to the synchronous belt 105 through the connecting plate 101, and the two door panels 1 are respectively connected and fixed to the synchronous belts 105 on the upper and lower sides of the drive wheel 104. A pulley 102 is rotatably installed on the connecting plate 101, and a guide rail 103 is installed on the car 2. The door panel 1 slides at the upper limit of the car 2 through the pulley 102 and the guide rail 103. This structure makes the movement of the door panel 1 more stable and smooth, reduces the friction and resistance during the movement of the door panel 1, and reduces the probability of door panel 1 jamming, shaking and other malfunctions. Meanwhile, the limiting sliding design ensures that door panel 1 always moves along the predetermined trajectory during movement, preventing deviation or derailment. This improves the accuracy and reliability of door panel 1's opening and closing, ensuring that it can open or close quickly and stably in emergencies, thus providing a guarantee for personnel escape. Furthermore, the structure is simple and compact, occupying little space and not excessively encroaching on the effective space inside the car 2, which is beneficial for the rational use of the car 2's interior space. A motor is installed at the top of the car 2, and the transmission wheel 104 is driven by the motor. When the transmission wheel 104 rotates, it drives the two door panels 1 to move in opposite directions via the synchronous belt 105 and connecting plate 101. The motor drives the transmission wheel 104 to rotate, and then the synchronous belt 105 and connecting plate 101 drive the door panels 1 to move. This transmission method has the advantages of smooth transmission, accurate transmission ratio, and high efficiency. The motor can provide stable and powerful power, ensuring that door panel 1 can open and close quickly and smoothly. The synchronous belt 105 drive can precisely control the moving distance and speed of the door panel 1, avoiding problems such as incomplete opening and closing or uneven speed of the door panel 1 caused by transmission errors. In emergencies, the rapid and accurate opening and closing of the door panel 1 can buy time for personnel to escape and improve escape efficiency. At the same time, this transmission method has a simple structure, is easy to maintain, and reduces the equipment failure rate and maintenance costs.
[0024] Example 2: To further improve the safety and practicality of the elevator escape car in emergency situations, for example, such as... Figures 1 to 4As shown, this utility model also includes: a top plate 204 installed at the top of the car 2, and a ventilation opening 208 provided on the top plate 204, which can ensure the air circulation inside the car 2. When the elevator is running normally, the ventilation opening 208 can prevent the air inside the car 2 from becoming polluted and odors from accumulating, providing passengers with a comfortable riding environment. In an emergency, when people are trapped in the car 2, the ventilation opening 208 can prevent oxygen deficiency in the car 2, maintain normal breathing, ensure the safety of people's lives, and avoid physical discomfort or even life-threatening situations caused by oxygen deficiency. It is conducive to people maintaining a clear mind and good physical condition for escape or waiting for rescue. A safety door 203 is installed on the top plate 204. First lighting lamps 201 are installed on both sides of the safety door 203 on the top plate 204. Support plates 202 are installed on both sides of the safety door 203 on the top plate 204. Second lighting lamps 205 are installed on the support plates 202. There are two sets of first lighting lamps 201 and second lighting lamps 205, and the two sets of first lighting lamps 201 and second lighting lamps 205 are symmetrically distributed on both sides of the safety door 203. The symmetrical distribution of multiple sets of lighting lamps increases the lighting range and brightness. Inside the car 2, two sets of first lights 201 can evenly illuminate every corner of the car 2, so that people can have sufficient lighting no matter where they are in the car 2, which makes it convenient for them to perform various operations, such as looking for escape tools and checking the surrounding environment. Outside the car 2, two sets of second lights 205 are symmetrically distributed on both sides of the safety door 203, providing escapers with a clear and comprehensive view, illuminating all directions of the external escape route, reducing blind spots, enabling escapers to accurately judge the surrounding situation, and avoiding going the wrong way or having accidents due to insufficient light, thus improving the safety and success rate of escape. A cam 207 is installed at the pivot of the safety door 203, and a push switch 206 is installed on the top plate 204 on one side of the safety door 203. The second lights 205 are connected to an external power source through the push switch 206. When the safety door 203 is opened, the cam 207 rotates with the safety door 203 and triggers the push switch 206. The second lights 205 are connected to an external power source through the push switch 206, realizing the linkage between the opening of the second lights 205 and the safety door 203. In an emergency escape, when personnel open the safety door 203, the cam 207 rotates with the safety door 203, triggering the push-button switch 206, and the second lighting 205 immediately illuminates, requiring no additional manual operation and ensuring timely lighting. This illuminates the external escape route for personnel exiting the elevator car 2, allowing them to quickly see their surroundings and avoid dangers such as collisions and falls due to insufficient light, greatly improving the safety and efficiency of the escape and buying valuable escape time.
[0025] Working principle: Under normal circumstances, the motor installed at the top of the car 2 drives the transmission wheel 104 to rotate. The transmission wheel 104 drives the connecting plate 101 to move through the synchronous belt 105. Since the two door panels 1 are respectively connected and fixed to the synchronous belts 105 on the upper and lower sides of the transmission wheel 104, and the door panels 1 slide at the upper limit of the car 2 through the pulley 102 and the guide rail 103, when the transmission wheel 104 rotates, it will drive the two door panels 1 to move in opposite directions through the synchronous belt 105 and the connecting plate 101, so as to realize the opening and closing operation of the door panels 1.
[0026] A safety door 203, a first lighting lamp 201, a support plate 202, and a second lighting lamp 205 on the support plate 202 are installed on the top plate 204 of the elevator car 2. Two sets of the first lighting lamp 201 and the second lighting lamp 205 are provided, symmetrically distributed on both sides of the safety door 203. A cam 207 is installed at the pivot of the safety door 203, and a push-button switch 206 is installed on one side of the safety door 203 on the top plate 204. The second lighting lamp 205 is connected to an external power source through the push-button switch 206. When the elevator encounters an emergency and needs to escape through the safety door 203 on the top plate 204, the safety door 203 is opened. At this time, the cam 207 rotates with the safety door 203. When the cam 207 rotates to a certain position, it triggers the push-button switch 206, causing the second lighting lamp 205 to light up and provide illumination for the escaping personnel.
