Description

Technical Field

[0001] This disclosure relates to the field of warning lights, and more particularly to a multifunctional warning light. Background Technology

[0002] Warning lights, as core devices widely used in various warning scenarios, directly affect the efficiency of warning information transmission due to their coverage and stability. Most existing warning lights are cylindrical or polyhedral in shape, with light evenly distributed 360 degrees. They provide either visual or audible warnings, or both. The warning light is fixed at red and blue, and the warning sound is generally a pre-set audio message, making them unsuitable for scenarios where the content needs to be changed temporarily.

[0003] Existing vehicle warning lights mostly do not support cigarette lighter control and cannot be used on portable mobile stands such as tripods, limiting their application scenarios. Summary of the Invention

[0004] In view of this, the present disclosure provides a multi-functional warning light, characterized in that it includes: a middle frame, a light-transmitting cover mounted on the top of the middle frame, a top cover mounted on the top of the light-transmitting cover, a bottom cover mounted on the bottom of the middle frame, a battery and a main board disposed within the middle frame, the battery being electrically connected to the main board, a charging port also provided on the side wall of the middle frame, the charging port being electrically connected to the battery and the main board, a communication module, a speaker, and LEDs mounted on the main board, a reflector being installed between the main board and the light-transmitting cover, the main board receiving instructions from the terminal to modify the voice broadcast content via the communication module, and controlling the speaker to broadcast according to the modified voice broadcast content; the charging port includes a DC power interface and a USB interface; a connecting nut is provided in the middle of the bottom cover. The main board receives instructions from the terminal via the built-in communication module, such as control instructions to modify the voice broadcast content, and then drives the speaker to accurately broadcast according to the updated voice content, realizing flexible adjustment and output of voice information, suitable for scenarios where content needs to be changed temporarily. In addition, the charging port of this multi-functional warning light is designed as a dual-interface type, including both a standard DC power interface that can be adapted to a cigarette lighter, and a universal USB interface, to adapt to different power supply and charging scenarios. The bottom cover has a central access nut for easy installation and fixing, connection to external brackets or other equipment, which enhances the applicability and installation flexibility of the overall structure.

[0005] In some embodiments, the motherboard receives voice input commands or control commands sent by the terminal to control the multi-functional warning light to turn on and off, and / or control the horn and / or LED beads to operate. For different horn alarm modes and application scenarios, corresponding broadcast content can be set as needed.

[0006] In some embodiments, a positioning module is installed on the motherboard, and the motherboard sends location information to the terminal through the positioning module. The motherboard receives forced alarm commands from the terminal, controls the horn and LEDs to operate, and sends real-time location information to the terminal. Location information can be latitude and longitude coordinates or electronic map location information. Each multi-functional warning light can send location information to the terminal, facilitating unified management and allocation of multiple multi-functional warning lights.

[0007] In some embodiments, the system also includes a cigarette lighter and a spring wire. The spring wire is a three-core cable, comprising a DC positive wire, a DC negative wire, and a control signal wire. One end of the spring wire is connected to the cigarette lighter, and the other end is inserted into a DC power interface. The cigarette lighter has two control switches that control the horn and / or the LED. The cigarette lighter and spring wire provide a convenient and stable onboard power supply for the multi-function warning light. This connection method is not only convenient and quick but also makes full use of the vehicle's own electrical system, ensuring the multi-function warning light operates continuously and reliably in various driving environments.

[0008] In some embodiments, the middle frame is also provided with two buttons, which are located on the two side walls of the middle frame opposite to the charging port. The motherboard receives commands input from the two buttons to control the speaker and / or LED beads. The commands input from the two buttons may include turning the strobe mode on and off, switching the LED bead color, adjusting the LED bead brightness, turning the speaker alarm mode on and off, and adjusting the speaker volume.

[0009] In some embodiments, the reflector is horn-shaped, one end of the reflector is fixed to the main board, the light-transmitting cover is overlaid on the reflector, the horn is located inside the reflector, the top of the horn is flush with the top of the light-transmitting cover, and the LED is located outside the reflector.

[0010] In some embodiments, the LEDs include red, blue, and yellow LEDs, arranged alternately. This alternating arrangement of colored LEDs creates a uniform distribution throughout the ring, ensuring that regardless of the color emitted, corresponding LEDs illuminate at all angles of the multi-functional warning light, resulting in uniform LED color and excellent warning effect.

[0011] The multi-functional warning light disclosed in this application integrates multiple functional units on its mainboard assembly, including a communication module for wireless or wired data transmission, a speaker for emitting sound alerts, and LEDs for illumination. A reflector structure is also provided between the mainboard and the light-transmitting cover. This reflector effectively reflects and guides light, improving the luminous effect and warning visibility of the LEDs. The mainboard receives instructions from the terminal via its built-in communication module, such as control instructions to modify the voice broadcast content, thereby driving the speaker to accurately broadcast the updated voice content. This allows for flexible adjustment and output of voice information, suitable for scenarios where content needs to be changed temporarily. Furthermore, the multi-functional warning light is equipped with a dual-interface charging port, including a standard DC power interface for use with cigarette lighters and a universal USB interface to adapt to different power supply and charging scenarios. A nut is located in the center of the bottom cover for easy installation and fixation, connection to an external bracket, or connection to other devices, enhancing the overall structural applicability and installation flexibility.

[0015] To fully understand this disclosure, detailed steps and structures will be presented in the following description to illustrate the technical solutions of this disclosure. Preferred embodiments of this disclosure are described in detail below; however, other embodiments may also be implemented in addition to these detailed descriptions.

[0016] Figure 1 Structural diagrams of multi-functional warning lights provided for some examples; Figure 2 Explosion structure diagrams for multi-functional warnings provided as examples; Figure 3 A schematic diagram of the charging port of a multi-functional warning light provided as an example; Figure 4 A schematic diagram of the bottom structure of a multi-functional warning light provided as an example. (Reference) Figure 1-3 The multi-functional warning light is cylindrical in shape, wider at the bottom and narrower at the top. It may include: a middle frame 1, a light-transmitting cover 2 installed on the top of the middle frame 1, a top cover 3 installed on the top of the light-transmitting cover 2, and a bottom cover 4 installed at the bottom of the middle frame 1. A battery 18 and a main board 15 are located inside the middle frame 1. The battery 18 is electrically connected to the main board 15. A charging port 110 is also provided on the side wall of the middle frame 1. The charging port 110 is electrically connected to the battery 18 and the main board 15. A communication module (not shown), a speaker 19, and LED beads 15a are installed on the main board 15. A reflector 6 is installed between the main board 15 and the light-transmitting cover 2. The main board 15 receives instructions from the terminal to modify the voice broadcast content through the communication module and controls the speaker 19 to broadcast according to the modified voice broadcast content.

[0017] The terminal can be equipment in a command center, a personal mobile phone or computer, a vehicle with a display screen and communication functions, etc. The communication module can be a 4G or 5G communication chip, which is installed on the motherboard 15 on the side opposite to the LED bead 15a. For example, at a car accident scene, it can broadcast "Accident ahead, slow down"; in rainy or snowy weather, it can be changed to "Slippery roads in rainy or snowy weather, please drive carefully"; at a traffic jam intersection, it can be changed to "Congestion ahead, please keep a safe distance" or "Congestion ahead, please change your route in advance", etc. The battery 18 is fixed to the middle frame 1 by a battery pressure plate 11 and screws. Battery foam is also provided between the battery 18 and the middle frame 1 to protect the battery 18.

[0018] refer to Figure 2 and 3 The charging port 110 may include a DC power interface 112 and a USB interface 111. The DC power interface 112 includes a DC positive port (e.g., DC 12V positive), a DC negative port (e.g., DC 12V negative), and a control line port. The USB interface 111 may be a TYPE-C charging interface. A charging board 16 is provided inside the charging port 110, and the charging board 16 is electrically connected to the motherboard 15. A charging plug 9 is also provided outside the charging port 110 to seal the charging port 110.

[0019] refer to Figure 2 The middle frame 1 has a protrusion in the center to accommodate the speaker 19. The main board 15 and the reflector cup 6 both have holes in their centers. The main board 15 and the reflector cup 6 are fitted onto the protrusion, with the top of the speaker 19 protruding outside the protrusion. The reflector cup 6 is horn-shaped, with one end fixed to the main board 15. The light-transmitting cover 2 covers the reflector cup 6, and the speaker 19 is located inside the reflector cup 6. The top of the speaker 19 is flush with the top of the light-transmitting cover 2, and the LED beads 15a are located outside the reflector cup 6. A speaker sealing ring 7 is also installed between the top of the speaker 19 and the light-transmitting cover 2 to better seal the speaker 19. The top cover 3 has multiple sound holes 3a in the middle corresponding to the top of the speaker 19. A mesh plate 10 is provided between the speaker 19 and the top cover 3, covering the sound holes 3a and the top of the speaker 19 to prevent external dust, rain, snow, or other dirt from entering the speaker 19.

[0020] The LED 15a includes red, blue, and yellow LEDs, arranged alternately. In some embodiments, one red, one blue, and one yellow LED can form a group, and multiple groups of these LEDs can surround the mainboard 15 to form a complete LED 15a. In other embodiments, three red, three blue, and three yellow LEDs can form a group, and multiple groups of these LEDs can surround the mainboard 15 to form a complete LED 15a. This alternating arrangement of LEDs of different colors results in a uniform distribution of LEDs throughout the ring, ensuring that regardless of the color emitted, corresponding LEDs illuminate at all angles of the multi-functional warning light, providing uniform color emission and excellent warning effect.

[0021] refer to Figure 4 The bottom cover 4 has a connecting nut 41 in the middle. The connecting nut 41 can be used to install various brackets, allowing the multi-functional warning lights to be used in various temporary structures. Multiple multi-functional warning lights installed on the brackets can be used to enclose various temporary controlled areas or safe areas. Combined with... Figure 2Multiple magnets 12 are disposed between the bottom cover 4 and the battery 18, and are respectively installed in multiple grooves of the bottom cover 4. Each groove has multiple evenly distributed holes at its bottom. These holes not only effectively reduce the physical shielding effect on the built-in magnets 12, ensuring that the magnetic force can fully penetrate and function, but also provide good ventilation and heat dissipation channels for the internal battery 18, helping to extend battery life and maintain stable device operation. The magnets 12 have strong adsorption capabilities, allowing the multi-functional warning light to be firmly attached to the surface of various iron products, such as car roofs or temporary tin sheds, making installation flexible and convenient.

[0022] refer to Figure 5 and Figure 6 The multi-functional warning light may also include a cigarette lighter 30 and a spring wire 50. The spring wire 50 is a three-core cable, consisting of a DC positive wire, a DC negative wire, and a control signal wire. One end of the spring wire 50 connects to the cigarette lighter 30, and the other end is inserted into the DC power interface 112. The cigarette lighter 30 has two control switches (31, 32), which can control the horn and / or the LED bulb. By using the cigarette lighter 30 and the spring wire 50, a stable onboard power supply can be conveniently provided for the multi-functional warning light. This connection method is not only convenient and quick but also makes full use of the vehicle's own electrical system, ensuring that the multi-functional warning light continues to work reliably in various driving environments.

[0023] Two control switches (31, 32) control the operation of the horn and / or LEDs, including switching the strobe mode, changing the LED color, adjusting the LED brightness, switching the horn alarm mode, and adjusting the horn volume. One of the control switches can also be used as a power switch; that is, when the power switch is pressed for the first time, the multi-functional warning light is powered on, and when pressed again, the horn and / or LEDs can be controlled to operate.

[0024] Continue to refer to Figure 1 and 2 The middle frame 2 also has two buttons (21, 22), which are located on the two side walls of the middle frame 2 opposite to the charging port 110. The main board 15 receives commands from the two buttons to control the speaker and / or LEDs. The two buttons (21, 22) include a power button 21 and a toggle button 22. Commands input by the two buttons can include turning the strobe mode on / off, switching the LED color, adjusting the LED brightness, turning the speaker alarm mode on / off, and adjusting the speaker volume.

[0025] In this embodiment, the control of the speaker and / or LED beads by the two control switches (31, 32) and the two buttons (21, 22) can be described as follows: The control switch 31 or the power button 21 is used to control the LED beads to work in the first working mode. For example, pressing it once will turn on the red and blue alternating flashing mode (specifically, the red LED bead flashes twice, the blue LED bead flashes twice, and then the red and blue LED beads flash twice synchronously at the same frequency). Pressing it a second time will turn off the first working mode, and so on. The flashing frequency of the LED beads can be 3-5Hz.

[0026] In the first working mode, press and hold the control switch 31 or the power button 21 for 3 seconds or more to turn on or activate the horn alarm mode. At the same time, the LEDs in the current mode will remain on. Press and hold again for 3 seconds or more to turn off or deactivate the horn alarm mode, and repeat in this cycle.

[0027] The speaker volume is set to maximum by default. To reduce the speaker volume, double-click control switch 31 or power button 21, then press and hold to adjust to the desired volume. The longer you hold the button, the lower the volume becomes. When the volume reaches zero, it returns to maximum. Release the button to complete the volume adjustment. During speaker volume adjustment, the speaker alarm mode and LEDs remain in their current states.

[0028] The control switch 32 or the toggle button 22 is used to control the LED beads to operate in the second working mode. For example, pressing it once switches to the red LED bead strobe mode, pressing it a second time switches to the blue LED bead strobe mode, pressing it a third time switches to the yellow LED bead strobe mode, pressing it a fourth time switches to the red LED bead clockwise rotation strobe mode, pressing it a fifth time switches to the yellow LED bead clockwise rotation strobe mode, pressing it a sixth time switches to the red and blue LED bead clockwise rotation strobe mode, pressing it a seventh time switches to the red and blue LED bead alternating strobe mode (specifically, the red LED bead flashes twice, the blue LED bead flashes twice, and then the red and blue LED bead flashes twice synchronously at the same frequency), and pressing it an eighth time turns off the second working mode; the LED bead flashing frequency can be 3-5Hz.

[0029] In the second working mode, press and hold the control switch 32 or the switch button 22 to turn on the speaker voice broadcast mode and play the voice content. At the same time, the LEDs in the current mode remain on. Press and hold again for 3 seconds or more to turn off the voice broadcast mode, and repeat in this cycle.

[0030] In the second operating mode, to adjust the speaker volume, double-click control switch 32 or toggle button 22. Other changes are as described above and will not be repeated here. If you need to modify the speaker's voice announcement content, you can do so through the terminal.

[0031] As is easily understood, the horn alarm mode and the horn voice broadcast mode can only be used in one mode at a time; once activated, the latter will replace the previous mode.

[0032] In some embodiments, the motherboard 15 receives voice input commands or control commands sent by a terminal to control the multi-functional warning light to turn on and off, and / or to control the horn 19 and / or LED beads 15a to operate. At this time, the multi-functional warning light also has a microphone device electrically connected to the motherboard for receiving voice input commands. The motherboard receiving voice input commands to control the horn and / or LED beads may include switching the strobe mode on / off, switching the LED bead color, adjusting the LED bead brightness, switching the horn alarm mode on / off, adjusting the horn volume, switching the forced alarm mode on / off, broadcasting the current remaining battery power, and broadcasting the current location.

[0033] The motherboard 15 receives control commands from the terminal to control the operation of the speaker 19 and / or LED beads 15a. These commands can include switching the strobe mode on / off, changing the LED bead color, adjusting the LED bead brightness, switching the speaker alarm mode on / off, adjusting the speaker volume, switching the forced alarm mode on / off, checking the remaining battery power, checking the current location, and checking the current operating mode. They also include editing, modifying, and uploading voice broadcast content, editing, modifying, and uploading speaker alarm modes (e.g., alarm modes for public security, fire, traffic police, emergency, civil defense, medical, municipal, railway, and water conservancy facilities), and modifying the LED bead flashing frequency. For different speaker alarm modes and application scenarios, corresponding broadcast content can be set as needed.

[0034] In some embodiments, a positioning module (not shown) is installed on the motherboard 15, which sends location information to the terminal. The positioning module can be a Beidou chip or a GPS chip. The positioning module and the communication module can be integrated into a single module, installed on the side of the motherboard 15 opposite to the LED bead 15a. The location information can be latitude and longitude information or electronic map location information, etc. Each multi-functional warning light can send location information to the terminal, facilitating unified management and allocation of multiple multi-functional warning lights by the terminal.

[0035] In some embodiments, the motherboard 15 receives a forced alarm command sent by the terminal, controls the horn 19 and LED beads 15a to operate, and sends real-time location information to the terminal. When the multi-function warning light is in the on / activated state, when the terminal issues a forced alarm command, the red LED beads of the multi-function warning light flash at a certain frequency (e.g., 8-10Hz), accompanied by a horn alarm sound, and simultaneously reports the current location information. During the forced alarm process, all current operating modes of the multi-function warning light are immediately overridden. Once the forced alarm is deactivated, it automatically reverts to the previous operating mode. One terminal can simultaneously send forced alarm commands to multiple multi-function warning lights to control all or some of the multi-function warning lights in a certain area to activate forced alarms, enhancing the warning effect and expanding the warning range. For moving multi-function warning lights (e.g., vehicle-mounted), after receiving the real-time location information sent by the multi-function warning light activating the forced alarm, the terminal can make timely adjustments based on the latest location information, allowing for flexible deployment.

[0036] When the multi-function warning light receives a forced alarm command and is in the process of triggering a forced alarm, you can double-click the power button to deactivate the alarm. Alternatively, you can deactivate the forced alarm via the terminal. After deactivating the forced alarm, the terminal will update synchronously, cancel the alarm notification for the corresponding multi-function warning light, and restore it to its initial state. During a forced alarm, if the multi-function warning light experiences abnormal conditions such as battery depletion or circuit failure, the terminal will display that the device is in a faulty state to remind the user to repair or replace it promptly.

[0037] The multi-functional warning light disclosed in this application supports multiple control methods, including voice operation, button operation, vehicle cigarette lighter operation, and terminal operation, making it convenient and flexible to use. Furthermore, the multi-functional warning light supports both USB charging and DC power supply, ensuring reliable power supply and high visibility.

[0038] The multi-functional warning light disclosed in this application integrates multiple functional units on its mainboard assembly, including a communication module for wireless or wired data transmission, a speaker for emitting sound alerts, and LEDs for illumination. A reflector structure is also provided between the mainboard and the light-transmitting cover. This reflector effectively reflects and guides light, improving the luminous effect and warning visibility of the LEDs. The mainboard receives instructions from the terminal via its built-in communication module, such as control instructions to modify the voice broadcast content, thereby driving the speaker to accurately broadcast the updated voice content. This allows for flexible adjustment and output of voice information, suitable for scenarios where content needs to be changed temporarily. Furthermore, the multi-functional warning light is equipped with a dual-interface charging port, including a standard DC power interface for use with cigarette lighters and a universal USB interface to adapt to different power supply and charging scenarios. A nut is located in the center of the bottom cover for easy installation and fixation, connection to an external bracket, or connection to other devices, enhancing the overall structural applicability and installation flexibility.
