Description

Technical Field

[0001] This invention relates to the field of emergency lighting technology, and more specifically to an intelligent emergency lighting control device. Background Technology

[0002] Emergency lighting provides illumination in emergency situations, such as power outages, fires, and earthquakes. It helps people evacuate quickly and safely, reducing chaos and panic, and helping them find exits and other key locations. However, emergency lighting is usually fixed in place. When people are trapped, it can be difficult for them to pinpoint the location of the emergency lights, making it difficult to quickly guide them.

[0003] Currently, there are some existing technologies that can control the switching on and off of lights via a voice-activated switch. For example, patent publication number CN216556863U mainly uses a voice-activated switch to control the lights, thus increasing the practicality of the intelligent emergency dual-headed light. In the event of a power outage in an emergency, the circuit breaker sensor detects the power failure, and the controller controls the battery to supply power to the lights, enabling normal operation. However, analysis shows that this technology has the following drawbacks: when there is a lot of smoke in the environment, the light illumination range of the emergency lights is limited, and the brightness of the light is blocked by the smoke, making it difficult to clearly illuminate the environment and resulting in a dark environment. Trapped individuals cannot quickly and accurately find the emergency lights. Based on this, the present invention provides an intelligent emergency lighting control device with a simple and ingenious structure that can automatically adjust its orientation and focus the light according to the location of the trapped person. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an intelligent emergency lighting control device to solve the technical problem that emergency lighting lights cannot automatically focus towards the location of disaster victims when there is a large amount of smoke in the environment.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An intelligent emergency lighting control device includes:

[0007] The enclosure has a light on top and a directional indicator light pointing to the safety exit. The enclosure is equipped with a smoke sensor and a voice-activated switch inside, which is connected to the smoke sensor.

[0008] A housing with refracting plates slidably mounted on both sides, each refracting plate being driven by two transmission components to move out of or retract into the housing; the transmission components are connected to a voice-activated switch; and

[0009] The switching component, located inside the housing and connected to the transmission component, drives two refractive plates extending from the housing to rotate in opposite directions, adjusting the light from the lighting fixtures towards the victims and focusing the light.

[0010] As a further aspect of the present invention: grooves are provided on both sides of the housing, and sealing strips are provided in the grooves; when the transmission assembly drives the refractive plate to translate, the refractive plate slides relative to the grooves and squeezes the sealing strips.

[0011] As a further aspect of the present invention: the two refractive plates are symmetrically arranged, and the two transmission components are symmetrically arranged, wherein the transmission components include:

[0012] The main gear is rotatably mounted inside the housing and driven to rotate by a drive source connected to a voice-activated switch. The main gear meshes with a main rack that is slidably mounted inside the housing.

[0013] A main shaft, fixedly connected to one side of a refractive plate, with two main shafts located between the two refractive plates. The top of the main shaft is rotatably connected to an assembly block, which is slidably mounted within a housing. The main shaft is connected to a main rack, and a secondary gear is coaxially fixedly mounted on the main shaft.

[0014] The secondary rack is movably installed inside the housing. When the refraction plate extends out of the housing, the main rack drives the secondary rack to move through the switching assembly, and makes it mesh with the secondary gear, thereby driving the refraction plate to rotate.

[0015] As a further aspect of the present invention: a stop is rotatably mounted on the main shaft, and when the refractive plate extends out of the housing, the stop abuts against the side wall of the housing; the switching assembly includes:

[0016] A wedge block is fixed to the main rack, and an inclined surface is provided on the side of the wedge block near the auxiliary gear. The distance between the top of the inclined surface and the auxiliary gear is smaller than the distance between the bottom of the wedge block and the auxiliary gear.

[0017] A guide block, fixed to the secondary rack and slidingly engaged with the inclined surface of the wedge block, wherein the top of the secondary rack is connected to the slider via an elastic telescopic rod, and the slider is slidably installed within the housing; and

[0018] A fixed block is fixed on a rotating ring, which is coaxially rotatably connected to the main shaft. A movable block is slidably mounted on the rotating ring, and the movable block is connected to the fixed block by an elastic element. The movable block is fixedly connected to the main rack. When the stop block abuts against the side wall of the housing, the main rack continues to move, causing the movable block to move synchronously. The movable block then slides away from the fixed block and stretches the elastic element, and the secondary rack meshes with the secondary gear.

[0019] As a further aspect of the present invention, a limiting plate is provided on the wedge block.

[0020] As a further aspect of the present invention: the smoke sensor is connected to the brightness switch of the lighting lamp.

[0021] As a further aspect of the present invention: an alarm is also provided on the enclosure, and the alarm is connected to a smoke sensor.

[0022] The beneficial effects of this invention are:

[0023] (1) In this invention, when the concentration of smoke in the environment reaches the threshold, the sound control switch is turned on to monitor human voices in the environment. The controller of the device calculates the location of the victim based on the sound control switch. Then, the two transmission components drive the two refractive plates to extend out of the housing. After the refractive plates extend out of the housing, the switching component drives the transmission component to rotate the two refractive plates in opposite directions to adjust the light of the lighting lamp towards the victim and focus the light. This can achieve automatic focusing of the light of the lighting lamp when there is a lot of smoke in the environment and focus it towards the location of the victim. This can quickly and accurately illuminate the area around the trapped person, ensuring that the trapped person can find the lighting lamp in time and move towards the safety exit according to the direction indicator. The two transmission components control the rotation of the two refractive plates respectively, which can achieve different rotation angles of the two refractive plates. This allows for adaptive adjustment of the rotation angles of the two refractive plates when there are victims in multiple directions, so as to accurately control the focusing range and focusing direction of the light, thereby assisting the victim to escape the disaster area quickly.

[0024] (2) In this invention, when the concentration of smoke in the environment reaches the threshold, the drive source drives the main gear to rotate, thereby driving the main rack to move, and then the main shaft moves synchronously to push the refraction plate out of the housing. The sound control switch is turned on to monitor human voices in the environment. The controller of the device calculates the location of the victim based on the sound control switch. Then the main rack drives the secondary rack to move through the switching component and meshes with the secondary gear to drive the refraction plate to rotate, which can focus the light of the lighting lamp towards the location of the victim.

[0025] (3) In this invention, when the secondary rack descends to the bottom of its movement path, the secondary rack and the secondary gear are on the same horizontal line. At this time, the refracting plate is fully extended out of the shell, and the stop block abuts against the side wall of the shell. Due to the limiting effect of the stop block, when the main rack continues to move, it will drive the movable block to move synchronously. Then the movable block slides away from the fixed block and stretches the elastic element. During this process, the main shaft cannot be translated. And due to the meshing transmission of the secondary rack and the secondary gear, the main shaft will rotate, which can realize the rotation of the refracting plate and enable the light to be focused towards the direction of the disaster victim.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-7 As shown, the present invention is an intelligent emergency lighting control device, comprising:

[0038] The box 1 has a light 2 on its top and a directional indicator light 3 pointing to the safety exit. The box 1 is equipped with a smoke sensor 5 and a voice-activated switch inside it. The voice-activated switch is connected to the smoke sensor 5.

[0039] A housing 6 has two slidably mounted refractive plates 7 on its sides. Each refractive plate 7 is driven by two transmission components 8 to move horizontally, extending out of or retracting into the housing 6. The transmission components 8 are connected to a sound-activated switch.

[0040] The switching component 9, which is located inside the housing 6 and connected to the transmission component 8, is used to drive the two refractive plates 7 extending out of the housing 6 to rotate in opposite directions, so as to adjust the light of the lighting lamp 2 toward the victim and focus the light.

[0041] In one embodiment, both the smoke sensor 5 and the voice-activated switch are existing technologies. This application does not improve them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of this application.

[0042] The enclosure 1 is equipped with a monitoring module that can monitor the power grid status in real time and immediately activate the emergency lighting mode when the voltage drops or drops to zero. The enclosure 1 is also equipped with a backup battery pack to ensure that its capacity is sufficient to ensure that the emergency lights can continue to operate. When the monitoring module detects that the power grid voltage is lower than the preset threshold or is completely disconnected, the emergency lighting control device will be activated, the backup battery pack will immediately start to supply power, and activate and light up all the preset emergency indicators and lights 2.

[0043] In practical application, in the initial state, the two refractive plates 7 are housed within the housing 6. When the mains voltage drops below a preset threshold or is completely disconnected, the emergency lighting control device is activated, and the backup battery pack immediately starts supplying power. At this time, the smoke sensor 5 monitors the smoke concentration in the environment. When the smoke concentration in the environment reaches a threshold, the sound-activated switch is turned on to monitor human voices in the environment. The device's controller calculates the location of the victim based on the sound-activated switch. Subsequently, the two transmission components 8 drive the two refractive plates 7 to translate and extend out of the housing 6. After the refractive plates 7 extend out of the housing 6, the switching component 9 drives the transmission component 8 to rotate the two refractive plates 7 in opposite directions to adjust... The light from the main lighting unit 2 is directed towards and focused on the victims. Even in environments with heavy smoke, the light from the main lighting unit 2 is automatically focused towards the victims, quickly and accurately illuminating their surroundings. This ensures that the victims can spot the main lighting unit 2 in time and move towards the safety exit according to the directional indicator 3. The two transmission components 8 control the rotation of the two refraction plates 7, allowing them to rotate at different angles. This enables the refraction plates 7 to be adjusted adaptively when victims are present in multiple directions, thus precisely controlling the focusing range and direction of the light and helping victims escape the disaster area quickly.

[0044] like Figures 1-3As shown, in a preferred embodiment of the present invention, grooves 10 are respectively provided on both sides of the housing 6, and a sealing strip 11 is provided in the groove 10; when the transmission assembly 8 drives the refractive plate 7 to translate, the refractive plate 7 slides relative to the groove 10 and squeezes the sealing strip 11.

[0045] In practical applications, when no disaster occurs, the sealing strip 11 can seal the groove 10, thereby preventing dust from entering the housing 6 and ensuring the stability of the device.

[0046] like Figures 3-8 As shown, in a preferred embodiment of the present invention, the two refractive plates 7 are symmetrically arranged, and the two transmission components 8 are symmetrically arranged. The transmission components 8 include:

[0047] The main gear 801 is rotatably mounted inside the housing 6 and is driven to rotate by a drive source, which is connected to a voice-activated switch. The main gear 801 meshes with the main rack 802, which is slidably mounted inside the housing 6.

[0048] A main shaft 803 is fixedly connected to one side of a refraction plate 7, and two main shafts 803 are located between two refraction plates 7. The top of the main shaft 803 is rotatably connected to an assembly block 806, and the assembly block 806 is slidably installed inside the housing 6. The main shaft 803 is connected to a main rack 802, and a secondary gear 804 is coaxially fixedly mounted on the main shaft 803.

[0049] The secondary rack 805 is movably installed inside the housing 6. When the refraction plate 7 extends out of the housing 6, the main rack 802 drives the secondary rack 805 to move through the switching component 9 and make it mesh with the secondary gear 804 to drive the refraction plate 7 to rotate.

[0050] In one embodiment, the driving source can be a motor assembly, a gear assembly or a pulley assembly driven by a motor, as long as it can make the main gear 801 rotate. This embodiment does not make specific limitations here.

[0051] In practical application, when the concentration of smoke in the environment reaches a threshold, the drive source drives the main gear 801 to rotate, thereby driving the main rack 802 to move, which in turn causes the main shaft 803 to move synchronously, so as to push the refraction plate 7 out of the housing 6. The sound control switch is turned on to monitor human voices in the environment. The controller of the device calculates the location of the victim based on the sound control switch. Then, the main rack 802 drives the secondary rack 805 to move through the switching component 9 and makes it mesh with the secondary gear 804, so as to drive the refraction plate 7 to rotate, which can focus the light of the lighting lamp 2 towards the location of the victim.

[0052] like Figures 3-8As shown, in a preferred embodiment of the present invention, a stop 12 is rotatably mounted on the main shaft 803. When the refractive plate 7 extends out of the housing 6, the stop 12 abuts against the side wall of the housing 6. The switching assembly 9 includes:

[0053] A wedge block 901 is fixed on the main rack 802, and an inclined surface is provided on the side of the wedge block near the auxiliary gear 804. The distance between the top of the inclined surface and the auxiliary gear 804 is smaller than the distance between the bottom of the wedge block and the auxiliary gear 804.

[0054] A guide block 902 is fixed to the secondary rack 805 and slides in engagement with the inclined surface of the wedge block 901. The top of the secondary rack 805 is connected to the slider 903 via an elastic telescopic rod 904, and the slider 903 is slidably installed inside the housing 6.

[0055] A fixed block 906 is fixed on a rotating ring 909, and the rotating ring 909 is coaxially rotatably connected to the main shaft 803. A movable block 907 is slidably mounted on the rotating ring 909, and the movable block 907 is connected to the fixed block 906 through an elastic element 908. The movable block 907 is fixedly connected to the main rack 802. When the stop block 12 abuts against the side wall of the housing 6, the main rack 802 continues to move, driving the movable block 907 to move synchronously. Then, the movable block 907 slides away from the fixed block 906 and stretches the elastic element 908, and the secondary rack 805 meshes with the secondary gear 804.

[0056] In one embodiment, the elastic telescopic rod 904 is a structure composed of nested multi-stage tubular components. In practical applications, it can also employ a gear and rack structure or an electric telescopic rod; this embodiment does not impose specific limitations. The elastic element 908 can be selected from, for example... Figure 8 The spring shown can be replaced by other elastic components, such as silicone pillars, spring sheets, etc., which are not specifically limited in this embodiment.

[0057] It should be noted that during the movement of the main rack 802, before the stop block 12 abuts against the side wall of the housing 6, the main rack 802 pushes the movable block 907 to move. At this time, the thrust of the main rack 802 is insufficient to stretch the elastic element 908. The movable block 907 and the fixed block 906 move synchronously, that is, the main shaft 803 moves synchronously.

[0058] In practical application, when the main rack 802 moves, it drives the wedge block 901 to move synchronously. When the wedge block 901 moves to the point where its inclined surface contacts the guide block 902, the guide block 902 contacts the top of the inclined surface. Subsequently, the main rack 802 continues to move, and relative sliding occurs between the inclined surface and the guide block 902, causing the guide block 902 to descend. The secondary rack 805 descends synchronously, and during this process, the elastic telescopic rod 904 is stretched. When the secondary rack 805 descends to the bottom of its movement path, the secondary rack 805 and the secondary gear 804 are in position. At the same horizontal line, the refracting plate 7 is fully extended from the housing 6, and the stop block 12 abuts against the side wall of the housing 6. Due to the limiting effect of the stop block 12, when the main rack 802 continues to move, it will drive the movable block 907 to move synchronously. The movable block 907 slides away from the fixed block 906 and stretches the elastic element 908. During this process, the main shaft 803 cannot move horizontally, and due to the meshing transmission of the auxiliary rack 805 and the auxiliary gear 804, the main shaft 803 will rotate, which can realize the rotation of the refracting plate 7, so that the light can be focused towards the direction of the disaster victim.

[0059] like Figures 4-5 As shown, in a preferred embodiment of the present invention, a limiting plate 905 is provided on the wedge block 901; in practical applications, the limiting plate 905 can prevent the guide block 902 from sliding off the preset path, ensuring the stability of the device operation.

[0060] like Figures 1-2 As shown, in a preferred embodiment of the present invention, the smoke sensor 5 is connected to the brightness switch of the lighting lamp 2; in practical applications, the brightness of the lighting lamp 2 can be adaptively controlled according to the ambient smoke concentration monitored by the smoke sensor 5, avoiding the problem of dim lighting when the smoke concentration is high.

[0061] like Figures 1-2 As shown, in a preferred embodiment of the present invention, the housing 1 is also equipped with an alarm 4, and the alarm 4 is connected to the smoke sensor 5; in practical applications, the alarm 4 can emit a buzzing sound to help the victims find the lighting 2, thereby accelerating the search for a safe exit.

[0062] Working principle of the invention: The above embodiments of the invention provide an intelligent emergency lighting control device. When the concentration of smoke in the environment reaches a threshold, the sound-activated switch is turned on to monitor human voices in the environment. The controller of the device calculates the location of the victim based on the sound-activated switch. Subsequently, two transmission components 8 drive two refraction plates 7 to translate and extend out of the housing 6. After the refraction plates 7 extend out of the housing 6, the switching component 9 drives the transmission components 8 to rotate the two refraction plates 7 in opposite directions to adjust the light of the lighting lamp 2 towards the victim and focus the light. This enables automatic focusing of the light of the lighting lamp 2 towards the victim when there is a lot of smoke in the environment, and can quickly and accurately illuminate the area around the trapped person, ensuring that the trapped person can find the lighting lamp 2 in time and move towards the safety exit according to the direction indicator 3. The two transmission components 8 control the rotation of the two refraction plates 7 respectively, which can achieve different rotation angles of the two refraction plates 7. This allows for adaptive adjustment of the rotation angles of the two refraction plates 7 when there are victims in multiple directions, so as to accurately control the focusing range and focusing direction of the light, thereby assisting the victim to quickly escape the disaster area.

[0063] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
