Abstract
Description
Technical Field
[0001] This utility model relates to the field of emergency lighting equipment technology, and in particular to an emergency lighting device for elevator cars. Background Technology
[0002] Elevator car emergency lighting is an important component of the elevator safety system. It provides lighting inside the car when the main power fails, facilitating passenger escape or waiting for rescue. Sufficient lighting can effectively reduce passenger panic in emergencies, helping them remain calm and respond rationally to unexpected situations. At the same time, it provides necessary light for rescuers to clearly see the situation inside the car, facilitating rescue operations and improving rescue efficiency.
[0003] To enhance aesthetics, existing high-end elevators use embedded emergency lighting devices. These devices require precise embedding into pre-reserved slots in the car during installation. The installation process involves meticulous calibration to ensure the device is flush with the car surface and prevent gaps that could affect lighting performance or aesthetics. If internal components of the light fixture are damaged, repairs require removing surrounding decorative parts before taking out the fixture. This process is complex, time-consuming, and can damage the car's interior due to repeated disassembly and reassembly, resulting in high repair costs and low efficiency. The current solution is to design a sliding or flip-up installation structure, installing rails on both sides of the pre-reserved slots in the car, with the light fixture mounted on a tray that can slide along the rails. When maintenance is needed, the lights can be slid out of the car along the slide rail by operating the external control handle, making it convenient for maintenance personnel to inspect them. However, the elevator operating environment is still complex, with a lot of dust and moisture inside the car. The emergency lighting device will accumulate dust, affecting the lighting effect. However, the outer shell of the emergency lighting device is mostly a one-piece design, making it difficult to open the shell for internal cleaning. Only the surface can be wiped. Over time, the accumulated dust will adhere to the lights, batteries and circuit boards, thus affecting the efficiency of cleaning and disassembly, and reducing the service life of the device. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0032] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides an emergency lighting device for an elevator car, comprising a frame 1, a disassembly and assembly mechanism 2 provided on the front side of the frame 1, the disassembly and assembly mechanism 2 being used for quick disassembly and assembly of the outer shell, thereby improving the efficiency of cleaning and maintenance of the device, a control board 3 being fixedly installed on the left end of the rear side of the inner wall of the frame 1, a backup power supply 4 being fixedly installed in the middle of the rear side of the inner wall of the frame 1, and a lighting device 5 being fixedly installed on the front side of the backup power supply 4. The control board 3 is used to switch the backup power supply 4, so that the lighting device 5 can be started in an emergency, a connector 7 being fixedly installed on the rear bottom side of the frame 1, and a heat dissipation device 6 being provided in the middle of the bottom wall of the frame 1.
[0033] The disassembly and assembly mechanism 2 includes a transparent shell 201. The rear side of the transparent shell 201 is set on the front side of the frame 1. The upper and lower sides of the transparent shell 201 are fixedly connected to the mounting frames 202, so that the transparent shell 201 completes the initial engagement and stability with the frame 1 under the sliding of the mounting frames 202. The two mounting frames 202 have engagement grooves 203 on the opposite sides. The upper and lower ends of the front side of the frame 1 are engaged with the corresponding engagement grooves 203. The left and right sides of the frame 1 are rotatably connected to two locking plates 204. Then, when the locking plates 204 are flipped, the grooves 205 on one side can engage with one side of the mounting frames 202, so as to complete further locking. At the same time, the fixing effect is improved with the cooperation of the locking components 206. The adjacent sides of the multiple locking plates 204 are provided with grooves 205. The left and right sides of the two mounting frames 202 are engaged with the corresponding grooves 205, and the disassembly of the device is completed, which improves the disassembly and assembly efficiency. The bottom side of one side of the locking plate 204 is provided with a locking component 206.
[0034] The locking assembly 206 includes multiple locking posts 2061. One end of each locking post 2061 is fixedly connected to the bottom side of a corresponding locking plate 204. When the locking plate 204 is flipped, the locking posts 2061 are flipped synchronously. Two locking slots 2062 are provided on both the left and right sides of the transparent shell 201, so that the locking posts 2061 can engage with the locking slots 2062 to improve the fixing effect. The other end of each locking post 2061 engages with the corresponding locking slot 2062.
[0035] Specifically, in the disassembly and assembly mechanism 2 on the front side of the frame 1, the engaging groove 203 on the side away from the mounting frame 202 can complete the initial installation with the frame 1. Then, the locking plate 204 connected to the frame 1 rotates and flips, and the groove 205 on the adjacent side engages with the left and right sides of the mounting frame 202. The locking post 2061 at the bottom of one side flips synchronously and engages with the locking groove 2062 on the left and right sides of the transparent shell 201 to improve the fixing effect. Conversely, disassembly is improved to increase efficiency. The control plate 3 at the left end of the rear side of the inner wall of the frame 1 switches the backup power supply 4 in the middle of the rear side of the inner wall to start the emergency lighting equipment 5 on its front side. The connector 7 fixed on the rear side of the bottom and the heat dissipation equipment 6 in the middle of the bottom wall work together to improve the overall cleaning and maintenance efficiency.
[0036] Reference Figure 1 , Figure 2 and Figure 5 The heat dissipation device 6 includes an extraction fan 601, the top of which is fixedly connected to the bottom of the frame 1. The inner bottom wall of the frame 1 has multiple flow grooves 602, through which airflow can be discharged. A filter shell 603 is fixedly installed on the top of the frame 1, and the bottom of the filter shell 603 is connected to the top of the frame 1. The filter shell 603 and the filter disc 604 can filter the gas, preventing particles from mixing in and damaging the equipment inside the device. Two filter discs 604 are fixedly connected to the left and right sides of the top wall of the filter shell 603. A dehumidification plate 605 is fixedly installed on the inner wall of the filter shell 603. The dehumidification plate 605 can adsorb water vapor in the airflow, thereby improving the heat dissipation effect.
[0037] Specifically, after the extraction fan 601 is started, the airflow inside the frame 1 flows out through multiple flow channels 602 opened in the inner bottom wall to achieve basic heat dissipation. The bottom of the filter shell 603 fixedly installed on the top of the frame 1 is connected to the top of the frame 1. The external gas is first initially filtered by two filter discs 604 fixedly connected to the left and right sides of the top wall of the filter shell 603, and then enters the interior of the filter shell 603. The dehumidification plate 605 fixedly installed on the inner wall adsorbs the water vapor contained in the airflow. The gas after drying enters the interior of the frame 1 to replenish the internal airflow. The filter shell 603 and the filter discs 604 work together to filter particulate impurities in the gas to prevent particles from mixing in and damaging the equipment inside the device. The dehumidification plate 605 reduces the impact of water vapor in the airflow on the equipment and works synergistically with the extraction fan 601 and the flow channels 602 to improve the overall heat dissipation effect.
[0038] Reference Figure 1 , Figure 4 and Figure 5 The heat dissipation device 6 also includes two rubber pillars 606, the tops of which are fixedly connected to the bottom left and right sides of the exhaust fan 601 respectively; rubber pads 207 are fixedly connected to the front and rear sides of the inner walls of multiple locking plates 204, and the inner wall dimensions of the multiple rubber pads 207 are matched with the outer wall dimensions of the mounting frame 202; the control board 3 is electrically connected to the backup power supply 4, the lighting device 5 and the connector 7 respectively, and the top of the connector 7 is fixedly connected to the bottom of the backup power supply 4.
[0039] Specifically, the two rubber pillars 606 can reduce the risk of damage to the bottom of the extraction fan 601, the multiple rubber pads 207 can improve the fixing effect on the mounting frame 202, and the electrical connection with the backup power supply 4, the lighting equipment 5 and the connector 7 respectively can enable the power switching of the lighting equipment 5.
[0040] Reference Figure 1 , Figure 2 and Figure 3 The left and right rear ends of the frame 1 are each fixedly connected to two mounting plates 8, and the front of the mounting plates 8 are each provided with mounting holes 9; the disassembly and assembly mechanism 2 also includes multiple protrusions 208, and the adjacent sides of the multiple protrusions 208 are respectively fixedly connected to the outer wall of the locking plate 204.
[0041] Specifically, the connection between the mounting plate 8 and the mounting hole 9 facilitates the installation and adjustment of the device's mounting position, and the multiple protrusions 208 facilitate the use of the locking plate 204.
[0042] Working principle: The locking plate 204, which is rotatably connected to the left and right sides of the frame 1, flips over, and the groove 205 on the adjacent side separates from the mounting frame 202 fixed to the upper and lower sides of the transparent shell 201. This releases the fixing of the locking plate 204 to the mounting frame 202. In the locking component 206 at the bottom of one side of the locking plate 204, the locking post 2061 flips over with the locking plate 204 and simultaneously separates from the locking grooves 2062 on the left and right sides of the transparent shell 201. Pulling the transparent shell 201 causes the engaging groove 203 on the side away from the mounting frame 202 to separate from the upper and lower ends of the front side of the frame 1, thus completing the removal of the transparent shell 201. Conversely, the mounting frame 202 slides, causing the engaging groove 203 to engage with the front side of the frame 1, achieving initial stability. The locking plate 204 flips over, causing the groove 205 to engage with the mounting frame 202 and the locking post 2061 to engage with the locking groove 2062, thus fixing the device and completing the installation. Through the above disassembly and assembly operations, the device can be easily opened for cleaning and maintenance, improving cleaning and maintenance efficiency and extending the service life of the device.
[0043] Furthermore, by starting the extraction fan 601, airflow is drawn through multiple flow channels 602, causing the airflow inside the device to flow downwards and be discharged through the flow channels 602. The bottom of the filter shell 603, which is fixedly installed at the top of the frame 1, is connected to the top of the frame 1. Outside air is first filtered by two filter discs 604 fixedly connected to the left and right sides of the top wall of the filter shell 603 to remove particulate impurities, and then enters the interior of the filter shell 603. The dehumidification plate 605, which is fixedly installed on the inner wall, adsorbs the moisture in the airflow to complete the drying. The filtered and dried air enters the interior of the frame 1 and exchanges heat with the equipment inside the device. After absorbing heat, it is discharged by the extraction fan 601 through the flow channels 602 with the internal airflow, improving the heat dissipation effect. The filter shell 603 and the filter discs 604 work together to prevent particulate impurities from entering and damaging the internal equipment. The dehumidification plate 605 reduces the impact of moisture on the equipment. The whole system works together to prevent the heat dissipation airflow from carrying too many particulate impurities and damaging the equipment.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
