Description

Technical Field

[0001] This application relates to the field of flashlight technology, and in particular to a magnetically controlled rotating structure for a diving flashlight. Background Technology

[0002] A diving flashlight, or diving light for short, is a professional lighting tool designed and manufactured specifically for underwater environments.

[0003] Most existing devices use push-button diving flashlights, but when used in environments with high water depth and high water pressure, the pressure is too great, making it difficult for users to press the button. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a magnetically controlled rotating structure and assembly method for a diving flashlight, which solves the problem that users have difficulty pressing the button due to excessive pressure when using it in environments with high water depth and high water pressure.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a magnetically controlled rotating structure for a diving flashlight, including a lamp holder and a lamp head, the lamp head being disposed on the lamp holder, a copper ring being disposed inside the lamp holder, a PCB main board being disposed inside the copper ring, a switch assembly for corresponding to different speeds of the flashlight being electrically connected to the PCB main board, and a rotating assembly for controlling the on / off state of the switch assembly being disposed on the lamp holder.

[0006] Furthermore, the switching assembly includes three Hall switches, which are respectively disposed on the top surface of the PCB motherboard and electrically connected. The rotating assembly includes a rotating ring and a magnet. The rotating ring is rotatably disposed on the lamp holder. The inner wall of the rotating ring has a receiving groove, and the magnet is disposed in the receiving groove.

[0007] Furthermore, the rotating assembly also includes steel balls and springs. The inner wall of the rotating ring is provided with a placement groove, the spring is placed in the placement groove, the steel ball is placed in the placement groove and abuts against one end of the spring, and the arc surface of the steel ball abuts against the top surface inside the lamp holder.

[0008] Furthermore, four positioning slots are provided on the top surface inside the lamp holder. The four positioning slots are located on the same arc line, and the steel ball abuts against one positioning slot. Three of the positioning slots correspond to three Hall switches.

[0009] Furthermore, a limiting groove is provided on the inner wall of the lamp holder, and the PCB motherboard is located in the limiting groove.

[0010] Furthermore, a limit block is provided on the lamp holder, and the limit block abuts against the inner wall of the rotating ring.

[0011] Furthermore, the outer wall of the lamp holder is provided with an annular groove, and a sealing ring is provided inside the annular groove.

[0012] Furthermore, a limiting pad is provided on the top surface of the lamp holder, and the top surface of the limiting pad abuts against the top surface inside the lamp head.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. In use, the three Hall switches correspond to the high, medium, and low brightness levels of the flashlight. Rotating the rotating ring on the lamp holder causes the magnet embedded in its inner wall to rotate. When the magnet approaches a Hall switch, the magnetic field strength reaches a preset threshold, triggering the switch and activating the corresponding circuit to switch to the appropriate brightness level. As the rotating ring continues to rotate, the magnet sequentially triggers different Hall switches, thus achieving flexible adjustment of the brightness level. This magnetically controlled rotating structure eliminates the need for axial reciprocating pressing, completely avoiding the problem of being unable to switch brightness levels due to excessive water resistance in high-depth, high-pressure environments. This significantly improves the ease of operation and reliability for divers under high-pressure conditions.

[0014] 2. The spring continuously provides elastic force to the steel ball, ensuring its spherical surface remains firmly in contact with the inner top surface of the lamp holder. As the rotating ring rotates, the steel ball rolls on its smooth top surface. Its spherical design converts sliding friction into rolling friction, significantly reducing rotational resistance. This makes gear shifting smooth and fluid with a clear feel, greatly improving the experience and efficiency of adjustment.

[0015] 3. The interaction between the steel ball and the positioning slots enables clear tactile feedback of the brightness levels and precise circuit control. When the steel ball engages in the first positioning slot, the circuit is disconnected, which is the "off" position of the flashlight. Continuing to rotate the ring, the steel ball slides into the subsequent three positioning slots, triggering the corresponding low, medium, and high brightness levels. This structure ensures clear and stable mechanical positioning for each level, providing users with strong tactile feedback. Users can accurately identify and switch levels by touch alone, without visual inspection, greatly improving the certainty and convenience of operation in dark or high-pressure underwater environments.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Example, refer to Figures 1-3 A magnetically controlled rotating structure for a diving flashlight includes a lamp holder 1 and a lamp head 2. The lamp head 2 is mounted on the lamp holder 1. A copper ring 11 is disposed inside the lamp holder 1, and a PCB main board 12 is disposed inside the copper ring 11. A switch assembly 3 for different flashlight speeds is electrically connected to the PCB main board 12. A rotating assembly 4 for controlling the on / off state of the switch assembly 3 is disposed on the lamp holder 1. The switch assembly 3 includes three Hall switches 31, which are respectively disposed on the top surface of the PCB main board 12 and electrically connected. The rotating assembly 4 includes a rotating ring 41 and a magnet 42. The rotating ring 41 is rotatably mounted on the lamp holder 1, and a receiving groove 411 is formed on the inner wall of the rotating ring 41. The magnet 42 is disposed in the receiving groove 411.

[0020] In use, the three Hall switches 31 correspond to the high, medium, and low brightness levels of the flashlight, respectively. Rotating the rotating ring 41 on the lamp holder 1 causes the magnet 42 embedded in its inner wall to rotate. When the magnet 42 approaches a Hall switch 31, the magnetic field strength reaches a preset threshold, triggering the switch and activating the corresponding circuit to switch to the corresponding brightness level. As the rotating ring 41 continues to rotate, the magnet 42 sequentially triggers different Hall switches 31, thus achieving flexible adjustment of the brightness level. This magnetically controlled rotating structure eliminates the need for axial reciprocating pressing, completely avoiding the problem of being unable to switch brightness levels due to excessive water resistance in high-depth, high-pressure environments, significantly improving the ease of operation and reliability for divers under high-pressure conditions.

[0021] The rotating assembly 4 also includes a steel ball 43 and a spring 44. The inner wall of the rotating ring 41 has a placement groove 412, within which the spring 44 is positioned. The steel ball 43 is also positioned within the groove and abuts against one end of the spring 44. The curved surface of the steel ball 43 abuts against the top surface inside the lamp holder 1. The spring 44 continuously provides elastic force to the steel ball 43, ensuring its spherical surface remains firmly against the top surface inside the lamp holder 1. When the rotating ring 41 rotates, the steel ball 43 rolls on its smooth top surface. Its spherical design converts sliding friction into rolling friction, significantly reducing rotational resistance. This makes gear shifting smooth and fluid with a clear feel, greatly improving the experience and efficiency of adjustment.

[0022] Four positioning slots 13 are formed on the top surface of the lamp holder 1, and the four positioning slots 13 are located on the same arc. The steel ball 43 abuts against one of the positioning slots 13, and three of the positioning slots 13 correspond to three Hall switches 31. Four positioning slots 13 are precisely machined along the same arc on the top surface of the lamp holder 1. This design, through the cooperation of the steel ball 43 and the positioning slots 13, achieves a clear tactile feel for the different brightness levels and precise circuit control. When the steel ball 43 is engaged in the first positioning slot 13, the circuit is disconnected, which is the "off" position of the flashlight. Continuing to rotate the rotating ring 41, the steel ball 43 will slide into the subsequent three positioning slots 13 in sequence, triggering the corresponding low, medium, and high brightness levels respectively. This structure ensures that each level has a clear and stable mechanical positioning, providing the user with strong tactile feedback. The user can accurately identify and switch levels by feel alone, without visual inspection, greatly improving the certainty and convenience of operation in dark or high-pressure underwater environments.

[0023] A limiting groove 14 is formed on the inner wall of the lamp holder 1, and the PCB main board 12 is located within the limiting groove 14. The PCB main board 12 is precisely positioned and firmly constrained by being embedded in the limiting groove 14 on the inner wall of the lamp holder 1, ensuring the accuracy and consistency of the relative positions between the PCB main board 12 and the Hall switch 31 and the rotating magnet 42 on it, thereby guaranteeing the reliability of the speed triggering. Secondly, it effectively prevents the PCB main board 12 from shifting or loosening when the flashlight is subjected to impact or vibration during carrying or underwater, improving the stability and vibration resistance of the overall structure, and facilitating quick and accurate installation of the main board.

[0024] A limiting block 15 is provided on the lamp holder 1, and the limiting block 15 abuts against the inner wall of the rotating ring 41. The core function of this limiting block 15 is to axially limit the rotating ring 41, preventing it from unnecessary movement or falling off along the axis of the lamp holder 1 during the use or carrying of the flashlight. Through continuous contact with the inner wall of the rotating ring 41, it ensures that the rotating ring 41 maintains stable rotation on a preset path, avoiding frictional noise, wear, or gear malfunction caused by loose parts, and improving the reliability of the structure.

[0025] The outer wall of the lamp holder 1 is provided with an annular groove 16, and a sealing ring 17 is provided in the annular groove 16. This structure, through the sealing ring 17 embedded in the annular groove 16 of the outer wall of the lamp holder 1, is compressed when the lamp head 2 is tightened with the lamp holder 1, forming an elastic sealing interface, which effectively prevents external moisture, gas and impurities from entering the interior of the lamp holder 1 from the joint gap.

[0026] A limiting pad 18 is provided on the top surface of the lamp holder 1, and the top surface of the limiting pad 18 abuts against the top surface inside the lamp head 2. When the lamp head 2 is finally tightened, its top surface abuts tightly against the top surface inside the lamp head 2, which effectively avoids excessive pressure or direct hard contact of metal parts, and also prevents the lamp head 2 from being tightened too much, thus improving the convenience of the device.

[0027] Working principle: In use, rotating the rotating ring 41 on the lamp holder 1 causes the magnet 42 embedded in its inner wall to rotate, compressing the spring 44 with the steel ball 43. When the steel ball 43 is engaged in the first positioning slot 13, the circuit is disconnected, which is the "off" position of the flashlight. Continuing to rotate the rotating ring 41, when the magnet 42 approaches the first Hall switch 31, the magnetic field strength reaches a preset threshold, triggering the switch and connecting the corresponding circuit to switch to the low brightness level. As the rotating ring 41 continues to rotate, the magnet 42 sequentially triggers different Hall switches 31, namely the medium brightness level and the high brightness level, thus achieving flexible adjustment of the brightness. This magnetically controlled rotating structure eliminates the need for axial reciprocating pressing operations, completely avoiding the problem of being unable to switch brightness due to excessive water resistance in high-depth, high-pressure environments, significantly improving the ease of operation and reliability for divers under high-pressure conditions.

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.
