Description

Technical Field

[0001] This application relates to the field of emergency lights, and more particularly to an emergency light with switchable emergency lighting modes. Background Technology

[0002] Emergency lights are safety lighting devices specifically designed for sudden power outages or extremely dangerous scenarios. Their core function is to automatically activate and provide continuous and reliable lighting when the main power supply system fails or when there is a sudden danger in the on-site environment. They can also serve as auxiliary functions such as evacuation guidance and hazard warning. They are key equipment in building fire protection, industrial safety, and public emergency systems.

[0003] Currently, most conventional dual-head emergency lights on the market have exposed emergency lighting heads, relying solely on the PC material of the light-transmitting cover for basic impact resistance. While this structure may meet basic protection needs in normal environments, it poses serious safety hazards in extreme disaster scenarios such as earthquakes or partial building collapses. When an earthquake causes wall collapse or falling rocks, the exposed emergency lighting head will directly bear the impact and pressure of the falling rocks. Existing light-transmitting covers are only single-layered or simply double-layered structures, and the connection bracket between the light head and the main body lacks dedicated impact-resistant buffering. If a falling rock impacts the light head, it can easily cause the light-transmitting cover to shatter, the LED light-emitting module to deform and be damaged, or even cause the entire light head to detach, rendering the emergency light completely ineffective. Utility Model Content

[0004] In order to ensure that the emergency light can still activate the backup lighting device when the emergency light head is damaged by falling rocks, this application provides an emergency light with switchable emergency lighting modes.

[0005] This application provides an emergency light with switchable emergency lighting modes, which adopts the following technical solution: An emergency light with switchable emergency lighting modes includes an emergency light holder, a load-bearing plate, a load-bearing spring, a light assembly, an auxiliary emergency light, and a push block. The emergency light holder is mounted on a wall. The load-bearing plate is horizontally positioned above the emergency light holder and slides vertically onto the emergency light holder. The light assembly is mounted on the upper surface of the load-bearing plate. The load-bearing spring keeps the load-bearing plate away from the emergency light holder. The auxiliary emergency light is located on one side of the emergency light holder and is fan-shaped. The auxiliary emergency light rotates around the center of the fan shape and is connected to the emergency light holder. The emergency light holder has a clearance hole for the auxiliary emergency light to protrude. The push block is mounted on the load-bearing plate and abuts against the inclined side wall of the auxiliary emergency light. When the load-bearing plate is supported by a heavy object, the push block pushes the auxiliary emergency light to rotate and protrude from the emergency light holder.

[0006] By adopting the above technical solution, through the linkage structure of the load-bearing plate, load-bearing spring and push block, the load-bearing plate moves down and pushes the fan-shaped auxiliary emergency light out of the lamp holder when a rock falls, which solves the problem of no backup lighting after the traditional emergency light head is damaged. It achieves the effect of automatically switching to auxiliary emergency lighting when the main emergency light is damaged, ensuring that emergency lighting is not interrupted in extreme disaster scenarios.

[0007] Optionally, the auxiliary emergency light is equipped with a protective plate, which is located on the side wall of the auxiliary emergency light that does not contact the push block. When the auxiliary emergency light protrudes from the emergency light base, the inclined protective plate can guide heavy objects such as falling rocks to fall.

[0008] By adopting the above technical solution, when the auxiliary emergency light is exposed, the protective plate is in an inclined state, which can guide falling rocks and other heavy objects to slide down. This can not only prevent falling rocks from damaging the auxiliary emergency light again, but also reduce the pressure of heavy objects on the light body, thereby improving the survival and working stability of the auxiliary emergency light in disaster scenarios.

[0009] Optionally, the load-bearing plate is provided with a support member for maintaining auxiliary lighting. The support member includes a support block, a support rotating plate, and a support spring. The support block is disposed on the lower end surface of the load-bearing plate. The emergency lamp holder is provided with a through hole to facilitate the entry of the support block into the interior of the emergency lamp holder. The lower end surface of the support rotating plate is rotatably connected to the support block. The support spring is used to keep the upper end surface of the support rotating plate away from the support block. When the support block enters the interior of the emergency lamp holder through the through hole, the upper end surface of the support rotating plate abuts against the inner top wall of the emergency lamp holder.

[0010] By adopting the above technical solution and utilizing the mechanical limiting structure of the retaining component, the auxiliary emergency light can be locked in position after the load-bearing plate moves down, ensuring that the auxiliary emergency light continues to maintain its turned-out lighting state and preventing the load-bearing spring from resetting and causing the auxiliary light to retract, thus ensuring the continuity and reliability of the auxiliary lighting.

[0011] Optionally, the light assembly includes two emergency lights, each emergency light having a mounting base and a rotating lamp head. The load-bearing plate is provided with two mounting tubes, which correspond to the two emergency lights. The mounting tubes are vertically arranged and located on the upper surface of the load-bearing plate. The mounting base is provided with mounting components, and the rotating lamp head is rotatably connected to the mounting base in a horizontal direction.

[0012] By adopting the above technical solution, and through the design of the mounting tube and the horizontally rotatable lamp head, the modular installation of the lamp group and the flexible adjustment of the lighting angle can be realized. This not only facilitates the disassembly and maintenance of the emergency light, but also adapts to the lighting range requirements of different scenarios, thereby improving the lighting adaptability of the main emergency light.

[0013] Optionally, the lamp holder is provided with a rotating rod, which is horizontally positioned. Several positioning strips are provided on the outer wall of the rotating rod, with the length of each positioning strip parallel to the length direction of the rotating rod. These positioning strips are evenly distributed circumferentially along the axis of the rotating rod. The rotating lamp head is provided with a rotating block, which has a rotating hole. The rotating block is rotatably connected to the rotating rod through the rotating hole. Several positioning grooves are provided within the rotating hole, distributed along the axis of the rotating hole. These positioning grooves are used to engage the positioning strips.

[0014] By adopting the above technical solution, relying on the locking cooperation between the positioning strip on the rotating rod and the positioning groove of the rotating block, multi-angle positioning of the rotating lamp head can be achieved, avoiding angular displacement of the lamp head due to vibration and other factors, ensuring the stability of the main emergency light's lighting direction, and guaranteeing the accuracy of evacuation lighting.

[0015] Optionally, the mounting component includes a snap-fit ​​block and a rotating cover. The mounting lamp holder is in the shape of a cylindrical tube. The snap-fit ​​block is disposed on the outer side wall of the mounting lamp holder. The inner side wall of the mounting tube has a snap-fit ​​groove. The mounting tube is snapped into the snap-fit ​​block through the snap-fit ​​groove. The rotating cover is coaxially disposed with the mounting lamp holder. The rotating cover is rotatably connected to the outer side wall of the mounting tube. The rotating cover is threadedly connected to the outer side wall of the mounting tube.

[0016] By adopting the above technical solution, using a snap-fit ​​block and a rotating cover with a threaded locking structure, the emergency light can be quickly snapped in and securely fixed, combining easy disassembly and assembly with connection stability, thus reducing the difficulty of installing and maintaining the emergency light.

[0017] Optionally, the mounting component further includes a corrugated pipe, one end of which is disposed on the mounting lamp holder, and the other end of which is disposed on the rotating lamp head. The wires of the rotating lamp head pass through the corrugated pipe, the mounting lamp holder, and the mounting tube in sequence and are inserted into the emergency lamp holder.

[0018] By adopting the above technical solution, the rotating lamp head wires are wrapped and protected with corrugated tubing, which not only meets the wiring requirements of the rotating lamp head, but also prevents the wires from breaking due to bending or wear, thus ensuring the safety and stability of the main emergency light circuit connection.

[0019] Optionally, the auxiliary emergency light is provided with a first metal conductive sheet, and the emergency light holder is provided with a second metal conductive sheet. The second metal conductive sheet is electrically connected to the power supply in the emergency light holder. When the auxiliary emergency light is exposed outside the emergency light holder, the first metal conductive sheet and the second metal conductive sheet are in contact.

[0020] By adopting the above technical solution, the contact conduction structure of the metal conductive sheet when the auxiliary emergency light is rotated out is utilized to realize the power-off when the auxiliary light is stored and the automatic power-on when it is popped out. No additional electronic control module is required, which reduces standby power consumption and ensures that the auxiliary light lights up as soon as it pops out, thereby improving emergency response efficiency and reliability.

[0021] Optionally: The auxiliary emergency light is provided with a first magnet, and the emergency light holder is provided with a second magnet on its side wall. When the auxiliary emergency light is located inside the emergency light holder, the first magnet and the second magnet attract each other.

[0022] By adopting the above technical solution, the auxiliary emergency light can be firmly fixed in the storage slot by the attraction force of the two magnets. This not only prevents the emergency light from loosening or accidentally popping out during daily transportation, installation, or minor vibration scenarios, ensuring the structural stability of the equipment in standby mode, but also ensures that when a falling rock impacts and triggers the load-bearing plate to move downwards, the magnetic attraction force can be smoothly overcome by the pushing force of the push block, ensuring that the auxiliary emergency light rotates out smoothly without jamming. In summary, this application includes at least one of the following beneficial technical effects: 1. Through the linkage triggering structure of the load-bearing plate, load-bearing spring and push block, the auxiliary emergency light is automatically rotated out when the main emergency light is damaged by falling rocks. With the limit locking function of the holding component, the auxiliary light can be kept in the lighting state continuously. At the same time, the tilting protective plate of the auxiliary light can resist the secondary impact of falling rocks, and the linkage conduction structure of the metal conductive sheet ensures that the auxiliary light lights up immediately after popping out and has no standby power consumption. The entire link from triggering, maintaining, protection to power supply solves the problem of easy failure of traditional emergency lights in disasters, and realizes uninterrupted emergency lighting in extreme scenarios. 2. Through the installation tube, the horizontally rotatable lamp head, and the snap-fit ​​structure of the positioning strip and positioning groove, the main emergency light's lighting angle can be flexibly adjusted and precisely positioned, avoiding vibration-induced deviation in the lighting direction. The snap-fit ​​block and the threaded locking structure of the rotating cover achieve a combination of quick disassembly and secure fixing. At the same time, the corrugated pipe protects the rotating lamp head's wires, eliminating the risk of wire wear and breakage caused by lamp head rotation, thus balancing the convenience of installation and maintenance with the long-term structural stability. 3. When the auxiliary emergency light is stored, it achieves power-off standby by separating it with a metal conductive sheet, eliminating the energy loss of an additional power control module and reducing the overall standby power consumption of the device.

Two mounting tubes 21 are mounted on the load-bearing plate 2, corresponding to two guide tubes 7. The mounting tubes 21 and guide tubes 7 are coaxially aligned and fixedly mounted on the upper surface of the load-bearing plate 2. The mounting tubes 21 communicate with the guide tubes 7. The mounting base 41 is cylindrical and has mounting components 43 for mounting onto the mounting tubes 21. The mounting components 43 include two snap-fit ​​blocks 431, a rotating cover 432, and a corrugated pipe 433. The two snap-fit ​​blocks 431 are circumferentially distributed along the axis of the mounting tube 21 and are fixedly mounted. The mounting tube 21 has two snap-fit ​​grooves 211 on the inner side wall of the mounting tube 21, which are used to snap with two snap-fit ​​blocks 431. The rotating cover 432 is coaxially arranged with the mounting tube 41 and is rotatably connected to the outer side wall of the mounting tube 41. The inner side wall of the rotating cover 432 is threadedly connected to the outer side wall of the mounting tube 21. One end of the corrugated tube 433 is fixedly set on the mounting tube 41, and the other end of the corrugated tube 433 is fixedly set on the rotating lamp head 42. The wire side of the rotating lamp head 42 passes through the corrugated tube 433, the mounting tube 41, the mounting tube 21, and the guide tube 7 and then passes into the emergency lamp holder 1 and is connected to the power supply in the emergency lamp holder 1.

[0032] Reference Figure 3 and Figure 4 The lamp holder 41 is also provided with two rotating rods 44, which are distributed circumferentially along the axis of the lamp holder 41. The rotating rods 44 are horizontally arranged and coaxially arranged. The rotating rods 44 are fixedly set on the outer wall of the lamp holder 41.

The inner wall of the rotating hole 46 is provided with several positioning grooves 47, the length direction of which is parallel to the axis of the rotating hole 46. The positioning grooves 47 are evenly distributed circumferentially along the axis of the rotating hole 46. The positioning strips 441 are used to engage with the positioning grooves 47.

[0033] Reference Figure 2 and Figure 5Two auxiliary emergency lights 5 are located on either side of the emergency light holder 1. A clearance hole 11 is provided on the corresponding side wall of the emergency light holder 1. The auxiliary emergency lights 5 are fan-shaped, with the arc surface of each auxiliary emergency light 5 located below it. Each auxiliary emergency light 5 is rotatably connected to the emergency light holder 1 along its central axis. Two push blocks 6 correspond to the two auxiliary emergency lights 5 and are fixedly mounted on the lower end face of the load-bearing plate 2. A guide slope 61 is provided on the lower end face of the push block 6 and on the side wall of the push block 6 facing the auxiliary emergency light 5. The guide slope 61 is used to abut against the side wall of the auxiliary emergency light 5 located within the emergency light holder 1. A protective plate 53 is provided on the side wall of the auxiliary emergency light 5 that is not in contact with the push block 6. A first magnet 51 is provided on the auxiliary emergency light 5, and a second magnet 12 is provided on the side wall of the emergency light holder 1. Reference Figure 2 and Figure 5 When the auxiliary emergency light 5 is located inside the emergency light holder 1, the protective plate 53 is attached to the side wall of the emergency light holder 1. The first magnet 51 on the auxiliary emergency light 5 and the second magnet 12 on the emergency light holder 1 are attracted to each other. A first metal conductive sheet 52 is fixedly installed on the auxiliary emergency light 5, and a second metal conductive sheet 13 is installed inside the emergency light holder 1. The second metal conductive sheet 13 is electrically connected to the power supply inside the emergency light 4. When the load-bearing plate 2 is impacted by falling rocks or other heavy objects, the side wall of the push block 6 abuts against the side wall of the auxiliary emergency light 5, and the auxiliary emergency light 5 rotates to the outside of the emergency light holder 1. The first metal conductive sheet 52 contacts the second metal conductive sheet 13, the auxiliary emergency light 5 is lit, and the protective plate 53 is tilted to guide falling rocks or other heavy objects away from the emergency light holder 1.

[0034] Reference Figure 2 and Figure 6 The load-bearing plate 2 is provided with a support member 8 for maintaining auxiliary lighting. The support member 8 includes a support block 81, two support rotating plates 82 and two support springs 83. The support block 81 is fixedly set on the lower end surface of the load-bearing plate 2. The emergency lamp holder 1 is provided with a through hole 14 to facilitate the support block 81 to enter the interior of the emergency lamp holder 1. The two support rotating plates 82 are located on the opposite side walls of the support block 81. The lower end surface of the support rotating plates 82 is rotatably connected to the support block 81 in the horizontal direction. The two support springs 83 correspond to the two support rotating plates 82. The support springs 83 are set horizontally. One end of the support spring 83 is fixedly set on the support rotating plate 82 and the other end of the support spring 83 is fixedly set on the support block 81. When the load-bearing plate 2 is impacted by heavy objects such as falling rocks, the support block 81 enters the emergency lamp holder 1 through the through hole 14. The support spring 83 drives the support rotating plate 82 to rotate. The upper end of the support rotating plate 82 abuts against the inner top wall of the emergency lamp holder 1.

[0035] The implementation principle of an emergency light with switchable emergency lighting modes according to an embodiment of this application is as follows: In normal state, after the emergency light holder 1 is fixed to the wall, the main emergency light 4 is installed by the snap-fit ​​block 431 and the snap-fit ​​groove 211 of the mounting tube 21, and then locked by the screw thread of the rotating cover 432. The rotating lamp head 42 can be adjusted by the cooperation of the rotating block 45 and the rotating rod 44. The positioning strip 441 is snapped into the positioning groove 47 to lock the angle. After being protected by the corrugated tube 433, the wire passes through each component in sequence and is connected to the power supply of the emergency light holder 1. Provides daily lighting; two auxiliary emergency lights 5 are housed in the through holes 14 on both sides of the emergency light holder 1, and are fixedly positioned by the attraction of the first and second magnets 12. At this time, the first and second metal conductive sheets 13 are separated, the auxiliary lights are powered off and in standby mode, and the protective plate 53 is attached to the side wall of the light holder; the load-bearing plate 2 is supported by the guide tube 7 and the load-bearing spring 3 and is in a horizontal state; the holding block 81 of the holding member 8 is suspended above the through hole 14 of the light holder, and the holding rotating plate 82 is tightly attached to the side wall of the holding block 81 under the tension of the holding spring 83, and the whole is in a standby state.

[0036] When a disaster such as an earthquake causes falling rocks to hit the load-bearing plate 2, the load-bearing plate 2 is driven by the impact force to move the guide tube 7 downward and compress the load-bearing spring 3. The push block 6, which moves downward at the same time, abuts against the side wall of the auxiliary emergency light 5 through the guide slope 61. The thrust overcomes the magnetic attraction force and causes the auxiliary light to rotate around the central axis to the outside of the lamp holder. During the rotation process, the first and second metal conductive plates 13 come into contact and conduct the power supply, and the auxiliary light automatically lights up. At the same time, the protective plate 53 is in an inclined state, which can guide subsequent falling rocks to slide down and avoid the auxiliary light from being subjected to secondary impact, thereby making up for the lighting function that the main emergency light 4 may lose due to damage.

[0037] When the load-bearing plate 2 moves down to the designated position, the holding block 81 enters the emergency light holder 1. The holding plate 82 rotates to both sides under the elastic force of the holding spring 83. Its upper end abuts against the inner top wall of the light holder to form a mechanical limit, preventing the load-bearing spring 3 from rebounding and causing the load-bearing plate 2 to move upward. This keeps the push block 6 in contact with the auxiliary emergency light 5, ensuring that the auxiliary light will not retract into the light holder. At the same time, the metal conductive sheet is in stable contact, and the auxiliary light can continue to provide illumination until the emergency power is exhausted or the main power is restored. After the disaster ends, the holding component 8 can be manually released to reset all components and the system returns to its normal standby state.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
