[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] In order to solve the technical problem that emergency indicator devices in the prior art cannot provide guidance for escapees, this utility model provides an emergency indicator device that provides guidance for escapees by forming lasers, thereby facilitating escape.

[0034] Please see Figure 1 The emergency indication device provided in this embodiment includes a housing 10 and a main control board 20, a power module 30, a lighting module 40, a laser generator 50, and a guidance module 60 installed on the housing 10. The power module 30, the lighting module 40, and the laser generator 50 are all connected to the main control board 20. The power module 30 is used to supply power to the main control board 20; the lighting module 40 provides illumination; the laser generator 50 is used to generate laser light; and the guidance module 60 is located on one side of the laser generator 50 and is used to change the path of the laser light generated by the laser generator 50 so that the laser guides people to escape.

[0035] Specifically, the emergency indication device comprises a housing 10, a main control board 20, a power module 30, a lighting module 40, a laser generator 50, and a guidance module 60. All of these components are housed within the housing 10. The main control board 20 is connected to the power module 30, lighting module 40, and laser generator 50. The power module 30 supplies power to the main control board 20, lighting module 40, and laser generator 50, maintaining their operation. In the event of an emergency such as a fire, the guidance module 60 alters the path of the laser generated by the laser generator 50, directing it towards the escape direction, thus providing guidance for those escaping and facilitating their escape, thereby ensuring their safety.

[0036] In this embodiment, the lighting module 40 can provide alarm and lighting.

[0037] In this embodiment, the main control board 20 includes a logic judgment module, a voltage acquisition module, a lithium battery charging management module, a stepper motor drive module, and a laser drive module. The logic judgment module uses a 32-bit CS32F103C8T7 MCU chip, the stepper motor drive module uses a SY6703HFC dedicated motor drive chip, and the lithium battery charging module uses an SLM6900 dedicated battery charging management chip. This combined chip solution of the main control board 20 can be used to implement functions such as logic signal processing, lithium battery charging and discharging, stepper motor driving, laser driving, and passive signal judgment.

[0038] In one embodiment, the outer casing 10 has a first pillar 11, and the main control board 20 is fixed to the first pillar 11. Specifically, the main control board 20 can provide stability inside the outer casing 10 through the pillar.

[0039] In one embodiment, please refer to Figure 1 The power module 30 includes two power boards. The two power boards are connected to the main control board 20 and the lighting module 40, respectively. The power board connected to the main control board 20 is equipped with an AC / DC power supply component and a DC / DC isolation module. The AC / DC power supply component and the DC / DC isolation module are model LH25-10B24ER2 and IB0505S-W75R3, respectively. This design features a wide main power input voltage range, strong anti-interference capability, and stable output voltage. The other power board is equipped with a large-capacity lithium battery and a lithium battery protection module. The lithium battery has a capacity of 3450mAh to ensure battery life. The lithium battery protection module uses a BM3451SMDC battery management chip, which can detect the voltage, charging and discharging current, and ambient temperature of each lithium battery cell.

[0040] In one embodiment, please refer to Figure 1The outer casing 10 also has a second column 12, and the lighting module 40 includes a light panel, which is fixed to the second column 12. Specifically, the light panel can be fixed to the outer casing 10 via the second column 12.

[0041] In this embodiment, the light board is an LED light board, which is equipped with an LED driver module and multiple LEDs. The LED driver module uses a dedicated LED driver chip of model PT4110. This chip is a high-efficiency boost converter chip that can drive multiple LEDs. It has the advantages of a large number of LEDs connected in series in a single channel and low power consumption. The LEDs are used to provide lighting.

[0042] Please see Figure 1 The two power boards are respectively fixed to the first column 11 and the second column 12 and are respectively connected to the main control board 20 and the light board. Specifically, the main control board 20, the light board and the two power boards form a four-circuit board structure. The main control board 20 and one of the power boards are electrically connected by wires, and the light board and the other power board are electrically connected by double-row pins. Through the four-circuit board structure and the fixation of the first column 11 and the second column 12, the stacked design of the main control board 20, the power module 30 and the lighting module 40 is realized, which greatly reduces the space occupation of the emergency indicator device, reduces the size of the emergency indicator device, and makes the device lightweight and portable.

[0043] Understandably, the guiding module 60 can change the laser path through reflection or refraction.

[0044] In one embodiment, please refer to Figure 1 The guidance module 60 includes a reflector 61 with a laser reflecting surface. This surface reflects the laser generated by the laser generator 50, guiding personnel through the reflected laser. Specifically, the laser reflecting surface is planar. By using the reflector 61, the guidance module 60 can alter the laser path of the laser generator 50 through reflection from the laser reflecting surface, thereby providing guidance for personnel escape.

[0045] In one embodiment, please refer to Figure 1 The rotating drive component 62 is connected to the main control board 20. The guidance module 60 also includes the rotating drive component 62. The rotating drive component 62 is connected to the main control board 20 and is used to drive the reflector 61 to rotate, so that the laser reflecting surface forms a reflected laser b within a fan-shaped area. Specifically, the rotating drive component 62 drives the reflector 61 to rotate, so that the incident angle and reflection angle entering the laser reflecting surface continuously change within a certain range, thereby forming a dynamic laser that is generally oriented towards the escape direction, which can alert the escape personnel and facilitate their escape.

[0046] In one embodiment, the range of the fan-shaped region is between 0 and 180°. Specifically, the reflector 61 can be a plane mirror or a multi-prism with four or more prisms. Taking a plane mirror as an example, when the laser reflecting surface is perpendicular to the laser reflecting surface through the rotation of the reflector 61, the incident angle and reflection angle of the laser are both zero. At this time, the original laser and the reflected laser b overlap.

[0047] As the reflector 61 rotates continuously, the incident angle of the laser increases continuously between 0 and 90°, and the reflection angle also increases continuously between 0 and 90°. In addition, the normal angle changes continuously between 0 and 90°, thus forming a laser reflection region between 0 and 180°.

[0048] When the laser beam rotates with the reflector 61 and becomes parallel to the laser reflecting surface, the incident laser beam a is parallel to the normal and no reflected laser beam b is formed.

[0049] In one embodiment, the reflector 61 is a prism structure, and the laser reflecting surface is formed on the side of the reflector 61. Specifically, as the laser rotates with the reflector 61,

[0050] It is understandable that the number of edges on the reflector 61 can be adaptively set according to actual needs, but it must be at least a four-sided structure. The more edges there are, the smaller the range of the resulting fan-shaped area. When the reflector 61 is a four-sided prism, the range of the fan-shaped area will be between 0-180°; when the reflector 61 is a hexagonal prism, the range will be between 0-120°; and when the reflector 61 is a dodecagonal prism, the range will be between 0-60°. As the reflector 61 rotates, the laser light will be reflected by each surface of the reflector 61, forming a continuously circulating reflected laser beam b within a certain range.

[0051] In one embodiment, the reflector 61 is a prism. Specifically, by setting the reflector 61 as a prism, a reflected laser b in the range of 0-180° will be formed.

[0052] like Figure 3 As shown, when a laser is incident on one end of the laser reflecting surface (i.e., the starting position of the laser reflecting surface), the incident laser a is located on one side of the normal, with both the incident angle and the reflection angle being 45°, and the reflected laser b is pointing downwards.

[0053] like Figure 4 As shown, when the reflector 61 rotates until the incident laser a is perpendicular to the laser reflecting surface (i.e., the initial position of the laser reflecting surface), the incident laser a overlaps with the normal. At this time, the incident angle and reflection angle of the laser are both zero, and the reflected laser b will be directed towards the laser generator 50 in a horizontal direction.

[0054] like Figure 5As shown, when the incident laser a is incident on the other end of the laser reflecting surface (i.e., the tail end of the laser reflecting surface) as the reflector 61 rotates, the incident laser a is located on the other side of the normal, and the incident angle and reflection angle are both 45°. The reflected laser b is pointing upwards, and finally a reflected laser b is formed in the range of 0-180°.

[0055] In one embodiment, the rotation drive 62 includes a stepper motor connected to the main control board 20. Specifically, the rotation of the reflector 61 is driven by the stepper motor.

[0056] In this embodiment, please refer to Figure 1 and 2 The housing 10 also includes two aviation connectors 13, two charging status indicator lights 14, and two buttons 15. Aviation connector XT1 connects to one of the power boards for AC 220V power supply, while aviation connector XT2 connects to the main control board 20 for passive fire signal reception. Both charging status indicator lights 14 are connected to the main control board 20; indicator light 14HL1 indicates the charging status, and indicator light 14HL2 indicates the fully charged status. Button 15SB1 is a power switch button 15, connected between aviation connector 13XT1 and the power board, used to control the connection and disconnection of external power. Button 15SB2 is a test button 15, connected to the main control board 20. The front panel of the housing 10 has an image to guide personnel to escape, and the rear panel of the housing 10 can be connected to a shock absorber and fixed to a wall.

[0057] Specifically, when the external main power supply is connected through the aviation connector 13XT1 and the power switch button 15SB1 is pressed, the device is powered by the external power supply. The external power supply converts AC220V to DC15V through the power board for charging the lithium battery. At the same time, the power board internally converts DC5V and DC3.3V to power the stepper motor, laser generator 50, and main control board 20MCU, respectively. The main control board 20MCU controls the corresponding relays to put the lithium battery on the power board into the charging state. During charging, the charging status indicator 14HL1 on the panel lights up. After the lithium battery is fully charged, the charging status indicator 14HL2 on the panel lights up. If an external alarm signal is transmitted to the device through the aviation connector 13XT2 or the test button 15SB2 is pressed, the main control board 20MCU receives the alarm or test signal and controls the corresponding relay to activate, thereby activating the laser generator 50, rotating the stepper motor, and illuminating the LED panel. When the external power supply fails, pressing the power switch button 15SB1 will activate the device, which will then be powered by the lithium battery on the battery board. The MCU on the main control board 20 will control the corresponding relays, causing the lithium battery to discharge. If an external alarm signal is received by the device at this time, either through the aviation connector 13XT2 interface or by pressing the test button 15SB2, the device will be activated.

[0058] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0059] When an alarm signal is triggered in an emergency such as a fire, the MCU on the main control board 20 receives the alarm or test signal and controls the corresponding relay to activate, thereby illuminating the laser generator 50 and the LED board. The stepper motor rotates, causing the reflector 61 to rotate synchronously. The laser generator 50 generates a laser and projects it onto the reflector 61. Driven by the stepper motor, the reflector 61 forms a continuously circulating reflected laser b within a range of 0-180°. The direction of the reflected laser b beam indicates the escape route for personnel.
