[0002] A flashlight, also known as a hand flashlight, is a portable lighting tool that uses batteries to provide illumination through light-emitting elements such as LEDs or bulbs. Its core function is to provide mobile and reliable light in environments where there is no fixed light source. It is widely used in many scenarios such as outdoor exploration, emergency rescue, daily maintenance, security patrol, and home backup. With the development of technology, users have put forward higher requirements for the functionality, reliability, and user experience of flashlights. A single lighting mode is no longer sufficient to meet the needs of use in complex scenarios. Therefore, focusing flashlights with multi-mode switching functions such as spotlight and floodlight have emerged.

[0003] Most commonly used focusing flashlights on the market employ mechanical focusing, primarily relying on mechanical contact switches to change the beam's focal length, thus switching between focused and floodlight effects. However, the frequent switching of traditional methods leads to contact oxidation and physical wear, which over time can cause poor contact, increased resistance, or even complete failure, severely impacting product lifespan. Furthermore, the mechanical sliding structure requires clearance, affecting the flashlight's overall sealing and making it difficult to achieve high levels of waterproofing and dustproofing, resulting in a higher failure rate in harsh outdoor environments. Therefore, those skilled in the art provide a flashlight with a nylon lens combination optical focusing device to address the problems mentioned in the background art. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figures 1-10As shown, this utility model provides a technical solution: a nylon lens combination optical focusing device flashlight, including a first housing 1 for protection, a second housing 2, and a mounting frame 3 for support. The second housing 2 is fixedly connected to one side of the first housing 1, and the mounting frame 3 is fixedly connected between the first housing 1 and the second housing 2. A combination optical lens 4 is fixedly connected to the upper part of the inside of the mounting frame 3, an LED light group 5 is fixedly installed to the upper part of the inside of the mounting frame 3, a PCB board 6 is fixedly connected to the middle part of the inside of the mounting frame 3, and a switching component 7 for adjusting the level of the LED light group 5 is installed inside the mounting frame 3.

[0026] Furthermore, the user operates the switching component 7 to generate an electrical signal. The control circuit on the PCB board 6 receives the signal and drives the LED light group 5 to emit light in different modes. The light passes through a fixed nylon composite optical lens 4, which integrates floodlight, focusing, and floodlight optical structures to ultimately form the desired lighting effect. This achieves electronic light pattern switching without moving the lens, abandoning the traditional mechanical moving focusing structure. The combination of electronic switching and fixed composite optical lens 4 significantly improves focusing reliability, waterproofness, and impact resistance. At the same time, the nylon lens material is heat-resistant and has good light transmission, ensuring stable and efficient output of the device in various modes. In addition, a sealing gasket is provided at the connection between the first housing 1, the second housing 2, and the mounting frame 3. The sealing gasket is compressed when the first housing 1, the second housing 2, and the mounting frame 3 are fastened together, tightly filling all mechanical gaps and forming a physical barrier. This effectively prevents the intrusion of liquid water and dust, achieving and maintaining the core structural guarantee of IPX5 or even higher waterproof and dustproof ratings. This significantly improves the reliability, durability, and safety of the flashlight in harsh environments such as humid, dusty, or rainy days.

[0027] It should be noted that the LED light group 5 is composed of independent LED chips, corresponding to floodlighting, spotlighting and floodlighting respectively. The working principle is that the control circuit on the PCB board 6 receives the instruction from the switching component 7 or the pressing switch 13, and precisely drives the specific LED chip or chip combination to emit light. The floodlight LED uses a color temperature of 5700K to achieve wide illumination, the spotlight LED uses a color temperature of 6500K to achieve long-distance projection, and the ultra-bright mode activates both groups of LEDs to the maximum power at the same time. After the light is shaped by the corresponding optical structure of the rear nylon combination optical lens 4, it finally outputs a highly efficient and distinct beam, which greatly improves the lighting adaptability, energy utilization efficiency and system reliability.

[0028] As one implementation method in this embodiment, please refer to Figures 6-10As shown, the switching component 7 includes a dial inner component 701 and an outer dial 702. The dial inner component 701 is installed inside the mounting frame 3. The outer dial 702 is rotatably connected to the upper part of the outer side of the first housing 1, and the output end of the outer dial 702 passes through the first housing 1. The output end of the outer dial 702 is fixedly installed in the middle of the dial inner component 701.

[0029] A first magnet 703 is fixedly installed on one side of the dial inner component 701. Two Hall effect sensors 704 are fixedly installed on one side of the PCB board 6. The two Hall effect sensors 704 are symmetrically arranged on both sides of the dial inner component 701. The first magnet 703 is located between the two Hall effect sensors 704. A spring plate 705 is fixedly connected to one side of the mounting frame 3. The spring plate 705 is located outside the dial inner component 701. A Hall effect switch 706 is installed on one side of the PCB board 6. Two guide grooves 707 are opened on the side of the dial inner component 701 near the mounting frame 3. Two limit grooves 708 are opened on the inner wall of each of the two guide grooves 707. Two mounting grooves 709 are opened on one side of the mounting frame 3. Springs 710 are fixedly connected to the inner wall of each of the two mounting grooves 709. Limit balls 711 are fixedly connected to the front end of each of the two springs 710. The limit balls 711 and the limit grooves 708 are matched.

[0030] Furthermore, when the user rotates the outer dial 702, it causes the inner dial component 701 to rotate. The first magnet 703, fixed to the inner dial component 701, changes position accordingly. Two symmetrically arranged Hall effect sensors 704 detect the change in magnetic field and convert it into an electrical signal. Combined with the Hall effect switch 706, this signal identifies the gear position. When the inner dial component 701 rotates, the guide groove 707 on the inner dial component 701 moves relative to the limiting ball 711 on the mounting frame 3. When adjusted to the first gear position, the two limiting balls 711, under the action of the spring 710, respectively engage with the limiting grooves 708 on the outer side of the two guide grooves 707, thereby... To achieve precise positioning and fixation of the first gear, when the dial inner component 701 is turned to the second gear, the limiting ball 711 engages with the limiting groove 708 in the middle of the guide groove 707, thereby achieving precise positioning and fixation of the second gear. When the dial inner component 701 is turned to the third gear, the spring plate 705 cooperates with the concave and convex structure on the dial inner component 701 to produce a clear gear position feel and positioning, thereby realizing completely non-contact electronic gear switching, completely avoiding mechanical contact wear and oxidation, greatly improving switching life and reliability, while having a compact structure, clear operating feel, and stable operation in harsh environments.

[0031] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the bottom of the first housing 1, the second housing 2 and the mounting frame 3 are all provided with a second magnet 8, and a metal back clip 9 is fixedly connected to the lower outer side of the second housing 2.

[0032] Furthermore, a magnetic field is generated by the second magnet 8 set at the bottom, which allows the flashlight to be attracted and fixed to the iron surface, achieving hands-free lighting. At the same time, the metal back clip 9 on the outside of the second shell 2 uses its elastic structure to clamp onto the edge of backpacks, belts and other objects, achieving portable fixation. This significantly improves the flashlight's portability and the versatility of its application scenarios. The magnetic function allows for quick positioning and stable hanging, while the back clip provides a reliable way to carry it. The combination of the two greatly enhances the product's practicality and user experience.

[0033] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, a power indicator light 10 is provided on the upper part of the outer side of the first housing 1, a charging port 11 is provided on one side of the mounting frame 3, and multiple grooves 12 are provided on the lower part of the outer side of the first housing 1.

[0034] Furthermore, the power indicator light 10 receives the power signal from the PCB board 6 and displays the remaining power of the battery 14 in a visually intuitive way with multi-color lights, allowing users to keep track of the power supply status in real time. The Type-C charging port 11 provides a fast, reversible charging experience, greatly improving charging convenience. The multiple grooves 12 significantly enhance grip stability and anti-slip effect by increasing surface friction and fit, optimizing the human-computer interaction experience, and achieving a comprehensive improvement in power visualization management, convenient charging operation, and grip safety.

[0035] As one implementation method in this embodiment, please refer to Figure 1 and Figure 4 As shown, a push switch 13 is installed in the middle of the outer dial 702. The output end of the push switch 13 is set on the PCB board 6. The combined optical lens 4 is made of nylon. A battery 14 is installed in the mounting frame 3. A reflector 15 is set in the mounting frame 3 and is located below the combined optical lens 4.

[0036] Furthermore, the push-button switch 13 located at the center of the outer dial 702 sends electrical signals to the PCB board 6 to achieve integrated control of power on / off, cyclic dimming, and mode switching. When the push-button switch 13 is short-pressed, it sends a short pulse signal to the PCB board 6. After receiving the signal, the PCB board 6 cycles through the brightness levels of the current mode according to a preset sequence and has a memory function, retaining the brightness level the next time the device is powered on. When the push-button switch 13 is long-pressed for several seconds, the PCB board 6 recognizes it as a power-off command, cuts off the power supply to the LED light group 5, and remembers the current level and brightness. Additionally, if the push-button switch 13 is quickly and continuously pressed twice, the PCB board 6 recognizes it as a special mode. Special commands trigger the ultra-bright mode or strobe function. The nylon composite optical lens 4 utilizes its high temperature resistance, high light transmittance, and deformation resistance to ensure stable output of multi-mode light effects such as focused light and floodlight. The built-in battery 14 provides power to the entire system, significantly improving the portability and ease of use of the device. The reflector 15 efficiently collects and redirects the light emitted by the LED light group 5, reflecting most of the light that was originally scattered to the side to the front. Working in conjunction with the composite optical lens 4, it converges or adjusts these reflected lights into a long-range or floodlight beam that meets the design requirements, significantly improving the utilization efficiency of the light source and the lighting effect, making the light spot more uniform and the brightness higher.

[0037] Working principle: The user moves the outer dial 702 with their finger. The rotation of the outer dial 702 causes the dial inner component 701, which is fixedly connected to it, to rotate together. When the dial inner component 701 rotates, the guide groove 707 on the dial inner component 701 will move relative to the limiting ball 711 on the mounting frame 3. When adjusted to the first position, the two limiting balls 711 are respectively engaged in the limiting groove 708 on the outer side of the two guide grooves 707 under the action of the spring 710, thereby achieving precise positioning and fixation of the first position. When component 701 is turned to the second position, the limiting ball 711 engages with the limiting groove 708 in the middle of the guide groove 707, thereby achieving precise positioning and fixation of the second position. When the inner component 701 is turned to the third position, the spring plate 705 cooperates with the concave and convex structure on the inner component 701 to produce a clear gear feel and positioning, thus forming three distinct gear positions: floodlight, spotlight, and non-locking position. A first magnet 703 is installed on the inner component 701. When the inner component 701 rotates, the first magnet... The position of 703 changes accordingly. Since two Hall effect sensors 704 are symmetrically mounted on the PCB board 6, when the first magnet 703 rotates to different positions, it will change the magnetic field strength at the Hall effect sensor 704 near it. The two Hall effect sensors 704 and the Hall effect switch 706 combine the detected magnetic signals into different level signal combinations and transmit them to the PCB board 6. The PCB board 6 determines the user-selected level based on the received specific level combination and drives the LED light group 5 to work in the corresponding mode. When in the floodlight mode, the PCB board 6 controls the floodlight LED in the LED light group 5 to light up at the set brightness. When in the spotlight mode, the PCB board 6 controls the spotlight LED in the LED light group 5 to light up at the set brightness. When in the extreme brightness mode, the PCB board 6 controls the floodlight LED and spotlight LED in the LED light group 5 to light up simultaneously, thereby achieving the extreme brightness. The adjustment process is without physical contact, avoiding the failure caused by arc oxidation and wear of traditional mechanical switches, and greatly improving the life and reliability of the device.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
