[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-10 This utility model discloses a magnetically controlled LED high-intensity flashlight, including a flashlight body 1, a head cover 7 at the bottom of the flashlight body 1, an aluminum-based lamp plate 11 at the bottom of the head cover 7, a circuit board 13 inside the head cover 7, an MCU integrated on the circuit board 13, a Hall effect sensor switch 131 integrated on the circuit board 13, a positioning ring 20 movably sleeved on the outside of the head cover 7, and a sensing magnetic block 23 matching the Hall effect sensor switch 131 on the positioning ring 20.

[0030] Specifically, the flashlight body 1 has a tail cap 3 on its top, and a magnet 5 is fixedly installed inside the tail cap 3.

[0031] In this embodiment, the magnet 5 allows the flashlight body 1 to be attached to a metal object, freeing the user's hands and adapting to different application scenarios. The tail cap 3 is interference-fitted with the flashlight body 1 to ensure assembly stability.

[0032] Specifically, the head cover 7 has a front cover 9 at its bottom, the front cover 9 has a lamp holder 10 inside, the aluminum-based lamp plate 11 is located at the bottom of the lamp holder 10, and the flashlight body 1 has a battery 6 inside that is electrically connected to the circuit board 13.

[0033] In this embodiment, the flashlight body 1 is interference-fitted with the head cover 7, and the front cover 9 is interference-fitted with the head cover 7 to improve assembly stability. The lamp holder 10 is used to support the aluminum-based lamp plate 11. The battery 6 is a rechargeable battery 6, which is charged through the charging interface 17.

[0034] Specifically, the aluminum-based lamp panel 11 is provided with a number of lamp beads, and the front cover 9 is provided with a lens 12 corresponding to the aluminum-based lamp panel 11.

[0035] In this implementation scheme, the multi-LED design increases the light intensity and provides wide-range, high-brightness illumination. The lens 12 is divided into compartments with the same number of LEDs, and each LED corresponds to an independent compartment.

[0036] Specifically, a steel ball sleeve 19 is fixedly installed inside the head cover 7. A steel ball 191 is movably installed inside the steel ball sleeve 19 by a spring. One end of the steel ball sleeve 19 extends to the outside of the head cover 7. The inside of the steel ball sleeve 19 is not connected to the inside of the head cover 7, and the outside of the steel ball sleeve 19 is fixed to the head cover 7 without gaps, so there will be no water leakage. The head cover is made of plastic material, which will not affect the sensing cooperation between the sensing magnetic block 23 and the Hall effect sensor switch 131. The positioning ring 20 has several positioning holes 22 inside. The end of the steel ball 191 away from the steel ball sleeve 19 extends into the inside of one of the positioning holes 22.

[0037] In this embodiment, the steel ball 191, together with the spring, is used to position the positioning ring 20. When the positioning ring 20 rotates, the relative position of the sensing magnetic block 23 changes. The Hall element detects the change in magnetic field strength and outputs a pulse signal. The MCU switches the preset brightness level according to the signal characteristics (such as frequency or amplitude). Each level has a corresponding positioning hole 22 to achieve positioning. When the positioning ring 20 rotates, the positioning ring 20 abuts against the steel ball 191 through the positioning hole 22, compressing the spring to rebound and avoid it. When the next positioning hole 22 is opposite to the steel ball 191, the spring rebounds and pushes the steel ball 191 into the interior of the positioning hole 22, thereby achieving the positioning of the positioning ring 20 and the shift ring 8.

[0038] Specifically, the head cover 7 is movably fitted with a shift ring 8 for driving the positioning ring 20.

[0039] In this embodiment, the shift ring 8 and the positioning ring 20 are engaged by a protrusion, so that when the shift ring 8 is rotated, the shift ring 8 drives the positioning ring 20 to rotate and switch gears.

[0040] Specifically, the circuit board 13 has a switch 14 and a charging interface 17 integrated on both sides. The switch 14 has a button 15 fitted on it. The cover 7 has a button retaining ring 16 fitted on one side and connected to the outside of the button 15. The cover 7 has a waterproof plug 18 corresponding to the charging interface 17 on the other side.

[0041] In this embodiment, the waterproof plug 18 protects the charging interface 17. By removing the waterproof plug 18, the charging cable can be connected to the charging interface 17 to charge the battery 6. The button 15 is a silicone waterproof button 15. The switch 14 presses the button 15 against one side of the inner wall of the head cover 7. The protruding part in the middle of the button 15 is fitted into the inside of the button pressure ring 16. Since the outer edge of one end of the button 15 is pressed tightly, there will be no water leakage when pressing the button 15. The switch 14 is used to switch the lighting mode.

[0042] Specifically, a leather case 2 is fitted over the outside of the flashlight body 1, and a pen clip 4 is fitted over the top of the flashlight body 1.

[0043] In this implementation, the pen clip 4 can be clipped to a pocket for easier use, and the leather case 2 is made of soft material for a more comfortable touch.

[0044] Specifically, sealing rings 21 are provided on the exterior of the flashlight body 1 and the head cover 7, as well as inside the front cover 9.

[0045] In this embodiment, sealing rings 21 are provided at both ends of the flashlight body 1, located inside the tail cap 3 and the head cap 7 respectively. Sealing ring 21 is provided on the head cap 7, located inside the front cover 9. Sealing ring 21 is provided inside the front cover 9, located on the outer ring of the lens 12. The arrangement of multiple sealing rings 21, combined with the tight connection of interference fit, effectively ensures the structural stability of the product.

[0046] In summary, this magnetically controlled LED high-power flashlight utilizes Hall effect magnetic induction technology to achieve contactless gear switching. Rotating the shift ring 8 causes the internal magnetic block to shift, triggering the Hall element and completely eliminating the physical wear and waterproofing risks associated with traditional mechanical switches 14. Its magnetically attached tail cap 3 design securely adheres to metal surfaces, freeing up hands for complex work scenarios. The fully sealed structure, combined with multiple waterproof rings and a silicone waterproof button 15, ensures complete isolation of the core circuitry from the external environment. The steel ball 191 spring positioning system provides clear gear feedback, and the lens 12's compartmentalized design ensures even beam distribution. The overall structure, through interference fit and the ergonomic design of the leather case 2 and pen clip 4, combines high protection with portability, making it a promising candidate for widespread application.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
