Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a flashlight to prevent accidental activation, including a body 1, with a connecting plate 101 integrally formed inside the body 1. A PCB assembly 2 is detachably connected to one side of the connecting plate 101, and an LED light board 3 is detachably connected to the other side of the connecting plate 101. A reflector 4 is provided on one side of the LED light board 3 and is fixed inside the body 1 by abutment. A mounting groove 102 recessed inward is provided on one side of the outer wall of the body 1. A gear shift knob 6 is slidably installed at one end of the mounting groove 102. A limiting structure that can cooperate with the gear shift knob 6 and the mounting groove 102 is provided. A mechanical linkage control structure is provided between the gear shift knob 6 and the PCB assembly 2. A mode button 7 is inserted into the other end of the mounting groove 102. The bottom of the mode button 7 is provided with a contact that can cooperate with the PCB assembly 2.

[0023] The tube body 1 and the connecting plate 101 are integrally formed from aluminum alloy to ensure structural rigidity. The PCB assembly 2 integrates power management and brightness control circuits and is symmetrically fixed to both sides of the connecting plate with the LED light board 3 by screws. The two are electrically connected by wires to form a symmetrical layout of the circuit control end and the light-emitting end. The bottom of the dial 6 is equipped with a T-shaped mechanical linkage. When sliding along the mounting groove 102, the linkage pushes the conductive slider assembly inside the tube body. In the locked position, the linkage pushes the slider to cut off the PCB power circuit; in the low light position, the linkage pushes the slider to connect the contact piece to the current-limiting resistor circuit, reducing the LED power supply current through the resistor to achieve low light; in the high light position, the linkage pushes the slider to connect the contact piece directly to the positive terminal of the battery to the LED circuit, with the current at full capacity, achieving high light. The linkage and the slider are engaged by a beveled guide groove to ensure stable force transmission during sliding and avoid jamming. The dial 6 and the mode button 7 are located on the same plane and on the same straight line, and the structural parts inside the tube body 1 are all located behind the conical arc of the reflector cup 4, maximizing the use of the internal space of the tube body 1.

[0024] Please see Figures 2 to 5 The bottom of the gear shift knob 6 is embedded with a ball spring 602. One end of the bottom inner wall of the mounting groove 102 is provided with several gear grooves 103. The several gear grooves 103 are evenly distributed along the movement trajectory of the ball spring 602. Each gear groove 103 is a corresponding ball inner surface groove structure of the ball spring 602.

[0025] The ball spring 602 consists of a stainless steel ball and a cylindrical helical spring, and is embedded in the stepped blind hole at the bottom of the dial 6. The gear position groove 103 at the bottom of the mounting slot 102 is a groove on the inner surface of the ball, which is evenly distributed along the sliding direction of the dial 6, corresponding to the locking, low light, and high light positions. When switching gears: the dial 6 is pushed to overcome the spring preload, and the steel ball disengages from the current groove; when sliding to the next gear, the steel ball is engaged in the new groove under the action of the spring force, producing a click-through feel. At the same time, the spherical meshing structure between the steel ball and the groove achieves physical gear position limitation. The purely mechanical feedback is precise and gear position switching can be sensed without electrical signals; the high fit between the inner surface groove of the ball and the steel ball makes the limiting stability better than the planar structure, improving the consistency of the operating feel and adapting to the blind operation needs in complex outdoor environments.

[0026] Furthermore, the limiting structure includes a limiting magnet 601, which is installed at the bottom of the gear shift knob 6, and a magnetic attraction part corresponding to the limiting magnet 601 is embedded on the inner wall of one end of the mounting groove 102.

[0027] The limiting magnet 601 is a neodymium iron boron magnet, fixed to the bottom of the dial 6 near the locking position via a countersunk hole and anaerobic adhesive. A magnetic block is embedded in the inner wall of the mounting groove 102 corresponding to the locking position, with opposite poles to the magnet. In the locked state, when the dial 6 slides to the leftmost position, the magnet and magnetic block attract each other, and the ball simultaneously engages with the locking position groove. With this double limiting, the dial 6 requires a significant pushing force to slide, completely preventing accidental unlocking. When unlocking, a pushing force is applied, causing the dial 6 to disengage from the magnetic attraction and compress the ball spring 602, entering the low or high light position. The magnetic attraction only applies to the locking position and does not interfere with smooth switching between other positions. Magnetic attraction strengthens the locking position, preventing accidental unlocking due to light touches on the dial 6. The layered limiting mechanism, combining mechanical and magnetic forces, ensures locking reliability while differentiating between locking / unlocking and position switching operations through varying pushing forces, balancing safety and ease of use, and adapting to the rapid unlocking needs of outdoor emergency scenarios.

[0028] Furthermore, the mode button 7 has an umbrella-shaped structure, including a flat button structure at the top and a trigger rod structure at the bottom. An insertion part 104 is provided at the other end of the bottom inner wall of the mounting groove 102. The trigger rod structure is inserted into the insertion part 104 and extends into the cylinder body 1. The bottom end of the trigger rod structure is provided with a contact point that can cooperate with each other at the corresponding position of the PCB assembly 2. A reset spring 701 is provided between the bottom of the flat button and the inner wall of the mounting groove 102.

[0029] The mode button 7 has an umbrella-shaped structure consisting of a flat pressing part and a cylindrical trigger rod. A flexible silicone cap is fitted to the bottom of the trigger rod and inserted into the insertion part 104 of the mounting slot 102. When pressed, the silicone cap deforms to fit the mode trigger area of ​​the PCB assembly 2, acting like a ring-shaped printed electrode. Different pressing durations correspond to different modes. After release, the return spring 701 pushes the button back to its original position, and the silicone cap returns to its original shape, achieving a momentary, flexible trigger. The button trigger is only recognized by the PCB when the toggle switch 6 is disengaged, completely avoiding accidental touches and crosstalk. The flexible silicone trigger balances reliability and tactile feedback, avoiding wear issues associated with rigid contacts. The logic chain from toggle switch unlocking to button triggering structurally eliminates accidental touches, adapting to rapid mode switching in complex outdoor scenarios.

[0030] Furthermore, a charging interface is provided on the PCB assembly 2, and a charging port docking groove 105 is provided on the outer wall of one side of the cylinder body 1 at the position corresponding to the charging structure.

[0031] PCB assembly 2 integrates a Type-C charging interface, with a gap reserved between the edge of the interface and the inner wall of the body 1 to avoid assembly interference; the charging port docking groove 105 on the outer wall of the body 1 is a rectangular recessed groove with rounded chamfers around the groove to guide the insertion of the charging plug, and a gap is reserved between the bottom of the groove and the charging interface to prevent the plug from directly squeezing the interface; the inner wall of the docking groove is sprayed with a hydrophobic and dustproof coating to reduce the probability of dust and water droplet adhesion and extend the life of the interface.

[0032] Furthermore, a connecting thread 106 is provided on the inner wall of the end of the cylinder body 1 away from the reflector cup 4.

[0033] The connecting thread 106 is machined on the inner wall of the tail section of the cylinder body 1. The inner wall of the adapter component (such as the battery compartment) is machined with a corresponding female thread. An O-ring can be optionally fitted to the tail end face. The thread balances sealing performance and disassembly efficiency. The standardized interface supports expansion such as battery compartment capacity expansion and magnetic tail cover, meeting users' needs for extended battery life and functional expansion.

[0034] Furthermore, the abutting part is a limiting pressure ring 5. The opening of the cylinder body 1 near the reflector cup 4 is provided with a snap-fit ​​structure corresponding to the limiting pressure ring 5. One end of the limiting pressure ring 5 abuts against the opposite end of the reflector cup 4, and the other end of the reflector cup 4 covers the outside of the light-emitting part of the LED light panel 3 and abuts against one side surface of the LED light panel 3.

[0035] The limiting pressure ring 5 is an aluminum alloy ring part. The front end opening of the cylinder body 1 is provided with an annular groove. The pressure ring 5 is provided with a corresponding snap-fit ​​protrusion and snaps into the groove. One end of the pressure ring 5 abuts against the end step of the reflector cup 4. The snap-fit ​​limiting method of the pressure ring 5 is relatively more efficient and stable in assembly.

[0036] Furthermore, the edge of the mounting groove 102 opening is provided with a snap-fit ​​structure, and a decorative panel 8 is detachably connected to it through the snap-fit ​​structure. The surface of the decorative panel 8 is provided with through grooves corresponding to the gear shift knob 6 and the mode button 7.

[0037] The decorative panel 8 has two sets of elastic barbs along its edge, corresponding to the slots in the mounting groove 102. Pressing the decorative panel 8 causes the barbs to engage in the slots, enabling tool-free assembly and disassembly. A long, narrow groove is cut into the surface of the decorative panel, corresponding to the gear shift knob 6, slightly wider than the knob and covering its sliding travel. A circular groove corresponds to the mode button 7, slightly larger in diameter than the button. The groove edges are chamfered to eliminate sharp edges and improve operational comfort. By concealing the internal mechanical structure, the appearance is cleaner and more unified. The elastic clips facilitate maintenance, and the chamfered groove optimizes the operating feel, solving the problems of dust accumulation and hand injuries associated with exposed structures, thus balancing protection and ease of use.

[0038] Working Principle: The integrated connecting plate 101 within the tube body 1 integrates the PCB assembly 2 and the LED light board 3. The reflector cup 4, via a limiting pressure ring 5, precisely surrounds the LED light board 3, ensuring the LED is positioned at the focal point. When the gear selector knob 6 slides, the ball spring 602 engages with the corresponding gear groove in the tube body 1, providing tactile feedback and basic limiting. The gear is locked by a limiting magnet 601, which enhances anti-accidental touch protection. The T-shaped connecting rod at the bottom of the knob 6 simultaneously pushes the conductive slider inside the tube, indirectly switching the power supply circuit of the PCB assembly 2, achieving high light, low light, and power-off locking gear logic. The mode button 7 uses an umbrella-shaped structure, triggered by elastic silicone, and only responds after the gear selector knob 6 is unlocked, completing the switching of modes such as strobe and SOS at the current gear. Ultimately, through the functional layering from the gear selector knob 6 to the mode button 7, the dual anti-accidental touch protection of mechanical limiting combined with magnetic reinforcement, and the circuit control of the mechanical connecting rod, a reliable locking, precise switching, and scene-adaptable lighting system is constructed, meeting the safety operation requirements in complex outdoor environments.

[0039] It should be noted that the specific model and specifications of PCB assembly 2 and LED light board 3 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The power supply and operating principle of PCB assembly 2 and LED light board 3 are clear to those skilled in the art and will not be described in detail here.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
