Abstract
Description
Technical Field
[0001] This application relates to the field of flashlight technology, and in particular to a dual-powered electronically controlled tactical flashlight. Background Technology
[0002] A flashlight is a handheld, portable electronic lighting tool. Most existing tactical flashlight switches require pressing a mechanical switch at the tail to turn on the power, and then lightly touching the head to switch modes to strobe mode. This is not well adapted to different people and different scenarios, and is not convenient to use. Utility Model Content
[0003] To address the shortcomings of existing technologies, the purpose of this application is to provide a dual-powered electronically controlled tactical flashlight, which solves the problem of not being well adapted to different people and different scenarios, and being inconvenient to use.
[0004] The above-mentioned objective of this application is achieved through the following technical solution: a dual-position electronically controlled tactical flashlight, comprising a shell, a head within the shell with a light-emitting unit for floodlighting, an LED switch PCBA for adjusting the brightness of the light-emitting unit on the inner side of the head, a main board PCBA for driving the LED switch PCBA on the inner side of the head, a head switch button for switching flashlight light modes and quick triggering on the outer side of the head, a head switch PCBA for electrical connection with the head switch button on the inner side of the head, a tail switch button for turning the flashlight on and off on the outer side of the tail, a tail switch PCBA for electrical connection with the tail switch button on the inner side of the tail, the main board PCBA being electrically connected to both the head switch PCBA and the tail switch PCBA, and a battery pack for continuously powering the main board PCBA in the middle of the shell.
[0005] Furthermore, a charging port is provided on the outer side of the casing head, and a charging board PCBA for charging and discharging the battery pack is provided on the inner side of the casing head.
[0006] Furthermore, the charging port uses a Type-C interface.
[0007] Furthermore, the light-emitting unit adopts a lamp panel.
[0008] In summary, this application includes at least one of the following beneficial technical effects: In emergency situations requiring direct activation of the strobe light, since the battery pack continuously powers the mainboard PCBA, the user simply needs to press and hold the head switch button. The head switch PCBA will then send a signal to the mainboard PCBA's MCU. Once the MCU detects that the signal duration exceeds a set threshold (e.g., 0.5 seconds), it will immediately interrupt any current operating mode and prioritize activating the highest-level strobe program, driving the light-emitting unit into strobe mode. This mechanism ensures that users can trigger a strong light deterrent with the fastest speed and simplest operation in critical moments, without needing to pre-power on via the tail switch or switch between multiple modes, significantly improving tactical response efficiency. When adjusting the flashlight brightness, the user can first power on the flashlight using the tail switch button, then switch between different brightness modes using the head switch button. Depending on the number of presses (e.g., 1 to 6 times), the user can sequentially switch between low, medium, high, ultra-high, strobe, and off modes. After use, a light press of the tail switch button sends a power-off command, putting the flashlight into the off state. This design balances rapid tactical response with ease of daily use, significantly improving the product's usability and user experience.
[0009] 2. In practical use, users can conveniently charge the flashlight via the charging port. The battery pack capacity is set at 37Wh, balancing long battery life and powerful performance while meeting the energy capacity restrictions for air transport, achieving an ideal balance between energy storage and portability. Furthermore, the charging system supports Type-C to Type-C connections, automatically identifying the device being charged and matching the appropriate voltage and current. In outdoor scenarios, a fully charged flashlight can also provide emergency charging for regular mobile phones and other devices, further expanding the device's practicality and portability.

[0012] The present application will be further described in detail below with reference to the accompanying drawings.
[0013] Example, refer to Figures 1-7 A dual-mounted electronically controlled tactical flashlight includes a housing 1. Inside the housing 1, a head-mounted light-emitting unit 2 for floodlighting is provided. Inside the head-mounted unit 1, an LED switch PCBA3 for adjusting the brightness of the light-emitting unit 2 is provided. Inside the head-mounted unit 1, a main board PCBA4 for driving the LED switch PCBA3 is provided. Outside the head-mounted unit 1, a head switch button 5 for switching flashlight modes and quick triggering is provided. Inside the head-mounted unit 1, a head switch PCBA6 for electrical connection to the head switch button 5 is provided. Outside the tail-mounted unit 1, a tail switch button 7 for turning the flashlight on and off is provided. Inside the tail-mounted unit 1, a tail switch PCBA8 for electrical connection to the tail switch button 7 is provided. The main board PCBA4 is electrically connected to both the head switch PCBA6 and the tail switch PCBA8. A battery pack 9 for continuously powering the main board PCBA4 is located in the middle of the housing 1.
[0014] In emergency situations requiring direct activation of the strobe light, since battery pack 9 continuously powers the mainboard PCBA4, the user simply needs to press and hold the head switch button 5. The head switch PCBA6 will then send a signal to the MCU on the mainboard PCBA4. Once the MCU detects that the signal duration exceeds a set threshold (e.g., 0.5 seconds), it will immediately interrupt any current operating mode and prioritize activating the highest-level strobe program, driving the light-emitting unit 2 into strobe mode. This mechanism ensures that the user can trigger a strong light deterrent with the fastest speed and simplest operation in critical moments, without needing to pre-power on via the tail switch or switch between multiple modes, significantly improving tactical response efficiency. When adjusting the flashlight brightness, the user can first power on the flashlight via the tail switch button 7, putting it into the "power on" state, and then switch between different brightness modes via the head switch button 5. Depending on the number of presses (e.g., 1 to 6 times), the user can sequentially switch between low brightness, medium brightness, high brightness, ultra-brightness, strobe, and off modes. After use, a light press of the tail switch button 7 sends a power-off command, putting the flashlight into the "power off" state. This design balances rapid tactical response with ease of daily use, significantly improving the product's usability and user experience.
[0015] A charging port 10 is located on the outer side of the head of the outer casing 1, while a charging board PCBA 11 for charging and discharging the battery pack 9 is located on the inner side of the head of the outer casing 1. In actual use, users can conveniently charge the flashlight through the charging port 10. The battery pack 9 has a capacity of 37Wh, balancing long battery life and strong performance while meeting the energy capacity restrictions for air transport, achieving an ideal balance between energy storage and portability. In addition, the charging system supports Type-C to Type-C connection, automatically identifying the device being charged and matching the appropriate voltage and current. In outdoor scenarios, the flashlight, when fully charged, can also provide emergency charging for regular mobile phones and other devices, further expanding the device's practicality and convenience for carrying when outdoors.
[0016] Charging port 10 uses a Type-C interface. When using the device, the Type-C interface supports reversible insertion, preventing wear and tear caused by incorrect insertion. Simultaneously, this interface type is compatible with charging cables for mainstream mobile phones, laptops, and other digital devices, eliminating the need for users to carry dedicated cables when out and about; a single cable can meet the charging needs of the flashlight and other devices, greatly enhancing convenience. Furthermore, the Type-C interface supports higher power transmission, contributing to faster charging speeds and further optimizing the product's practical value.
[0017] The light-emitting unit 2 adopts a lamp board design. By adopting a lamp board design for the light-emitting unit 2, precise positioning of the LED light-emitting core can be achieved. Combined with optical lenses or reflectors, a more uniform and dark spot-free ideal light spot can be formed, improving the lighting quality and visual effect, and meeting the stringent requirements of tactical lighting for light shape quality.
[0018] Working principle: 1. In an emergency requiring direct activation of the strobe light, since battery pack 9 continuously powers the mainboard PCBA4, the user only needs to press and hold the head switch button 5. The head switch PCBA6 will then send a signal to the MCU on the mainboard PCBA4. Once the MCU detects that the duration of this signal exceeds a set threshold (e.g., 0.5 seconds), it will immediately interrupt any current operating mode and prioritize activating the highest-level strobe program, driving the light-emitting unit 2 into strobe mode. This mechanism ensures that the user can trigger a strong light deterrent with the fastest speed and simplest operation in a crisis, without needing to pre-power on via the tail switch or switch between multiple modes, significantly improving tactical response efficiency.
[0019] 2. When adjusting the flashlight brightness, the user can first turn on the flashlight using the tail switch button 7 to put it into the "on" state, and then switch between different brightness modes using the head switch button 5. Depending on the number of presses (e.g., 1 to 6 times), the user can sequentially switch between low brightness, medium brightness, high brightness, ultra-brightness, strobe, and off modes. After use, a light press of the tail switch button 7 sends a power-off command, putting the flashlight into the "off" state. This improves the device's rapid response and ease of daily use, significantly enhancing the product's practicality and user experience.
[0020] The embodiments described in this specific implementation are 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.
