Description

Technical Field

[0001] The utility model relates to the technical field of elevator components, and more specifically, to a safety lighting device for an elevator. Background Art

[0002] An elevator is a mechanical device used for vertical transportation of people or goods within a building, and is widely used in high-rise buildings, shopping malls, hotels, hospitals, residences and other places. The design and functions of an elevator can vary depending on its use and the type of building, but generally include the following main components: a car, a door system, a drive system, a control system, guide rails, a counterweight, and a lighting device. The lighting device inside the elevator not only provides sufficient light to ensure the comfort and safety of passengers, but also enhances the aesthetics and experience inside the elevator. The lighting inside the elevator is usually automatically managed by the elevator control system and adjusted according to the operating state of the elevator. For example, when the elevator stops at a certain floor and is not in use, the lighting will be automatically dimmed or turned off to save energy, and when someone enters the elevator, the lighting will be automatically turned on or brightened.

[0003] However, the existing lighting devices for elevators have the following problems when in use:

[0004] (1) According to the existing elevator structure principle, the elevator is provided with two doors, the car door and the landing door. The car door is the door that moves with the elevator car. Landing door leaves are provided on each floor and are linked to open. This necessarily results in a movement gap between the car door and the landing door, which should not be greater than 35 mm according to the national standard requirements. The illumination in this gap is usually insufficient. If the passengers cannot observe clearly, it is easy for personal belongings to fall into this gap and fall into the hoistway. If an object with a small diameter size (high heels, shopping cart wheels, stick-shaped objects, etc.) gets stuck in this gap, it will further cause the person carrying the item to stay here for a long time, posing a great danger;

[0005] (2) The current elevator lighting device only provides simple lighting inside the elevator and cannot actively remind of different operating conditions and risks according to different states. For example, it cannot remind and warn of some illegal behaviors of passengers and some routine operations of maintenance personnel, which is likely to cause potential safety hazards.

[0006] The utility model can actively remind passengers of safety risk points, remind and stop illegal behaviors, improve the safety of passengers when taking the elevator, and standardize the behavior of taking the elevator safely. Summary of the Utility Model

[0007] The purpose of the utility model is to solve the technical problems put forward in the above background art and provide a safety lighting device for an elevator.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will combine with the drawings in the embodiments of the present utility model Figures 1-4 to clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0027] Please refer to Figures 1-4 , in the embodiments of the present utility model, a safety lighting device for an elevator includes: a car 1, a first monitoring mechanism, a detection mechanism 7, a first controller 6, and a second controller 601. A car door 101 is provided on one side of the car 1. A first sill 2 is fixedly provided at the bottom end of the side of the car 1 where the car door 101 is provided. A lighting strip 3 for reminding passengers of the elevator operation status is installed on the first sill 2. The first monitoring mechanism and the second controller 601 are fixedly provided on the car 1 and are signal-connected. The first monitoring mechanism is used to monitor whether the elevator reaches the leveling position, and the second controller 601 is used to control the opening and closing of the car door 101. The first controller 6 is fixedly provided on the car 1 and is used to control the opening and closing of the lighting strip 3. The detection mechanism 7 is fixedly provided on the car door 101 and is signal-connected to the first controller 6 and is used to detect the opening and closing state of the car door 101.

[0028] Further, the first sill 2 includes a first part provided below the car door 101 and a second part protruding outside the car door 101. The bottom ends of the first part and the second part are fixedly connected, and the upper ends are spaced apart. The first part is provided with a downward-opening U-shaped groove 202. A plurality of sliders 102 are fixedly connected to the lower end of the car door 101, and one end of the slider 102 is hooked into the U-shaped groove 202.

[0029] The slider 102 is hooked inside the U-shaped groove 202 to assist the car door 101 in sliding on the first sill 2 to realize the opening and closing of the car door 101. Moreover, the bottom of the slider 102 is hook-shaped, which can better cooperate with the U-shaped groove 202 and has an additional protection function of preventing the car door 101 from derailing, protecting against accidents where the door leaf derails due to passengers or goods hitting the elevator door.

[0030] Further, a car footrest 201 is further provided at the bottom of the first sill 2. An inspection opening is provided on the car footrest 201. The second controller 601 is installed on the side of the car footrest 201 close to the car 1.

[0031] Further, a second sill 5 is provided at the entrance and exit of each floor leading to the car 1. The second sill 5 is spaced apart from the first sill 2. The lighting strip 3 is embedded on the side of the first sill 2 facing the second sill 5. A landing footrest 501 is provided at the bottom of the second sill 5, and the landing footrest 501 is disposed opposite to the car footrest 201 provided at the bottom of the first sill 2.

[0032] Further, a lamp slot 203 is provided on the side of the first sill 2 close to the second sill 5, and the lighting strip 3 is embedded in the lamp slot 203.

[0033] Further, a detection groove 502 is formed on one side of the second sill 5 close to the car 1. The first monitoring mechanism includes a detection column 503 located inside the detection groove 502. An auxiliary hole 204 is provided on one side of the first sill 2 close to the second sill 5. The detection column 503 is engaged with the auxiliary hole 204 for monitoring the state of the car 1. The lighting strip 3 is installed in the lamp groove 203. The lighting strip 3 is protected by the first sill 2 and, through the bevel angle of the lamp groove 203, completely covers the gap area between the elevator sills to remind passengers of this dangerous area. At the same time, the lighting strip 3 can emit different lights according to different states of the elevator. When the car 1 reaches the landing, the detection column 503 sends a detection signal to the auxiliary hole 204. After this signal is received by the second controller 601, an opening signal is sent, and the car door 101 is opened.

[0034] Further, the detection mechanism 7 includes two sensing elements 701 respectively fixed to the upper ends of the two doors of the car door 101. The two sensing elements 701 are arranged in a matching manner. When the car door 101 is opened, the two sensing elements 701 on the detection mechanism 7 are separated, transmitting a separation signal to the first controller 6, so that the first controller 6 receives the opening information and can send an opening light instruction to the lighting strip 3. When the car door 101 is closed, the sensing elements 701 are in contact with each other, and the detection mechanism 7 sends a contact signal. The first controller 6 receives the closing information sent by the detection mechanism 7, so that the first controller 6 sends a closing light operation instruction to the lighting strip 3.

[0035] Specifically, since the second controller 601 shares a set of control systems with the first controller 6, when the second controller 601 receives a signal, the first controller 6 can also receive the signal synchronously. When the second controller 601 receives the signal from the first monitoring mechanism and issues an opening signal to open the car door 101, the first controller 6 correspondingly issues an opening signal to the detection mechanism 7, and issues a signal to control the lighting strip 3 to emit a yellow light and flash. When the car door 101 is fully opened, the lighting strip 3 is constantly lit with a green light. When the car door 101 is closed, the lighting strip 3 also flashes yellow. When the car door is fully closed, the lighting strip 3 automatically turns off. If the car 1 is not in the leveling position and a passenger forcibly opens the car door 101, at this time, if the car door 101 is forcibly opened and the detection mechanism 7 does not receive the opening signal, the sensing element 701 is manually separated, and the auxiliary hole 204 does not receive the signal of the detection column 503. At this time, the first controller 6 issues an instruction to the lighting strip 3. After the lighting strip 3 turns on a red light, it flashes and is accompanied by a voice reminder "The door leaf has been opened. Danger, danger. Please stop the illegal operation." In the inspection and maintenance mode (when maintaining and inspecting the device), it can be set according to the user's usage habits. When maintaining and servicing the elevator (when elevator maintenance personnel maintain and service the elevator as required: a voice reminder "Please apply a door stop device after opening the door and pay attention to the dangerous gap" should be added, and the display mode of the light strip is also different, and it should be a flashing yellow light), at the same time, it can make passengers notice the light at this place, playing a role in avoiding dangerous areas.

[0036] Preferably, the elevator is equipped with a built-in broadcast device, which is used to remind passengers that the car door 101 is opened when the car door 101 is opened, and to remind passengers that the car door 101 is closed and the elevator is about to rise when the car door 101 is closed. While the voice broadcast is accompanied by the flashing of the lighting strip 3, the safety of passengers during elevator rides is improved, and the behavior of taking the elevator safely is standardized.

[0037] In the embodiment of the present utility model, when the car 1 normally ascends or descends to the leveling position, a signal is sent to the auxiliary hole 204 through the detection column 503 in the second sill 5. The auxiliary hole 204 receives the signal and forwards it to the second controller 601. The second controller 601 sends an opening signal, and the car door 101 slowly opens. When it opens, the sensing element 701 separates. At this time, the detection mechanism 7 sends a signal to the first controller 6. The first controller 6 receives the signal from the detection mechanism 7 and sends an opening light signal to the lighting strip 3. When the car door 101 is fully opened, the lighting strip 3 remains constantly on until it is about to close. When it slowly closes, since the second controller 601 and the first controller 6 share the same control system, when the second controller 601 sends a closing signal, the first controller 6 can send an instruction to the lighting strip 3 to make the lighting strip 3 return to the flashing state again, reminding the passengers that the car door 101 is in the closing state at this time. After the car door 101 is closed, the first controller 6 sends an instruction to turn off the lighting strip 3. At this time, the car 1 resumes the working state and continues to ascend or descend.

[0038] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these changes and modifications.
