DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0025] The present utility model embodiment provides a flashlight adjustment module 1000, such as Figure 1-3 The flashlight adjustment module 1000 includes: a housing 100, a PCB board 200 and an adjustment component 300. A mounting frame 101 is provided in the housing 100, a through hole 102 is provided on the mounting frame 101, and a window 601 connected to the mounting frame 101 is opened on the housing 100; the PCB board 200 is located in the housing 100, a potentiometer 2011 is provided on the PCB board 200, and a switch 2021 is located at the through hole 102; the adjustment component 300 is arranged on the mounting frame 101, the adjustment component 300 is rotatably connected to the housing 100, and the adjustment component 300 is partially exposed through the window 601 The mounting frame 101 is provided with a receiving groove 104 which is respectively connected with the through hole 102 and the window 601. The adjusting component 300 passes through the through hole 102 and is arranged adjacent to the switch 2021. An elastic member 500 is provided between the adjusting component 300 and the through hole 102. There is a movable gap between the adjusting component 300 and the receiving groove 104, so that the switch 2021 can be triggered by pressing the adjusting component 300 through the window 601 to switch the gear. The adjusting component 300 is connected with the potentiometer 2011 so that when the adjusting component 300 rotates through the window 601, the potentiometer 2011 is adjusted to focus.

[0026] The adjustment component 300 is arranged on the mounting frame 101, and the mounting frame 101 is provided with a receiving groove 104, and there is a certain movable gap between the adjustment component 300 and the receiving groove 104, so that the adjustment component 300 can be displaced relative to the receiving groove 104. The adjustment component 300 can be displaced in the housing 100 by pressing the adjustment component 300 through the window 601 connected to the mounting frame 101, so as to trigger the switch 2021 on the PCB board 200 to achieve gear switching. The adjustment component 300 is connected to the potentiometer 2011 on the PCB board 200, and the adjustment component 300 is rotated through the window 601 to achieve the focus adjustment of the potentiometer 2011. This design makes the structure of the flashlight adjustment module 1000 simpler. At the same time, the user can adjust the brightness and focal length of the flashlight more conveniently and simply by pressing and rotating the part of the adjustment component 300 exposed in the window 601.

[0027] Specifically, an elastic member 500 is disposed between the adjustment component 300 and the through hole 102 , which can provide a certain buffer and stability to prevent the adjustment component 300 from loosening or shaking during the process of pressing the switch 2021 .

[0028] Further, refer to Figure 2 The shell 100 includes a cover plate 600 , a window 601 is disposed on the cover plate 600 , a sinking groove 103 is opened on the shell 100 , and the cover plate 600 is disposed in the sinking groove 103 .

[0029] By providing a window 601 on the cover plate 600, the adjustment capability of pressing or rotating the adjustment assembly 300 can be realized through the window 601. A sinking groove 103 is provided on the housing 100, and the cover plate 600 is arranged in the sinking groove 103, so that the cover plate 600 can be fixed and stabilized. The sinking groove 103 provides a space for accommodating the cover plate 600, so that the cover plate 600 can be firmly fixed on the housing 100 to prevent it from loosening or shaking. It helps to maintain the overall structure of the housing 100 stable and prevent the cover plate 600 from accidentally falling off or shifting.

[0030] refer to Figure 1 and Figure 3 The PCB board 200 includes a vertically arranged horizontal plate 201 and a vertical plate 202, the switch 2021 is arranged on the vertical plate 202, the potentiometer 2011 is arranged on the horizontal plate 201, and the adjustment component 300 includes a rotating shaft 302, a pressing rod 303 and a dial wheel 301. One end of the rotating shaft 302 is rotatably connected to the housing 100, and the other end is connected to the potentiometer 2011. The dial wheel 301 is clamped with the rotating shaft 302, and a part of the dial wheel 301 is exposed through the window 601. One end of the pressing rod 303 is in contact with the rotating shaft 302, and the other end passes through the through hole 102 and corresponds to the switch 2021. An elastic member 500 is provided between the pressing rod 303 and the through hole 102.

[0031] The two ends of the rotating shaft 302 are rotatably connected to the housing 100 and the potentiometer 2011 respectively, and the rotating shaft 302 is engaged with the dial wheel 301. By turning the dial wheel 301 exposed outside the window 601 to control the rotation of the rotating shaft 302, the potentiometer 2011 can be adjusted, thereby adjusting the brightness and focal length of the flashlight light. This arrangement makes the adjustment operation of the flashlight adjustment module 1000 more convenient, and the user can achieve precise adjustment through a relatively simple rotation.

[0032] Specifically, the PCB board 200 adopts a vertical connection method of the vertical board 202 and the horizontal board 201, the switch 2021 is set on the vertical board 202, and the potentiometer 2011 is set on the horizontal board 201, so that the connection structure is more compact, the space can be effectively utilized, and the volume of the entire module is small, which is easy to carry and use.

[0033] Specifically, one end of the pressing rod 303 abuts against the rotating shaft 302, and the other end passes through the through hole 102 and corresponds to the switch 2021, and an elastic member 500 is provided between the pressing rod 303 and the through hole 102. By pressing the part of the dial wheel 301 exposed outside the window 601, the adjustment component 300 is displaced in the housing 100 toward the switch 2021, so that the rotating shaft 302 squeezes the pressing rod 303, and the pressing rod 303 passes through the through hole 102 and contacts the switch 2021, thereby triggering the switch 2021 to switch gears. This design makes the operation more convenient, and the user can switch different brightness gears by simply pressing the window 601 without additional operations.

[0034] Specifically, an elastic member 500 is disposed between the pressing rod 303 and the through hole 102 , which can provide a certain buffer and stability to prevent the adjustment component 300 from loosening or shaking during use.

[0035] Furthermore, in this embodiment, the outer surface of the thumbwheel 301 is provided with anti-slip stripes.

[0036] The presence of the anti-skid stripes can provide additional friction and increase the anti-skid performance of the dial wheel 301. When the user touches the dial wheel 301 with a finger or palm, the anti-skid stripes can increase the friction between the finger and the surface of the dial wheel 301, reducing the possibility of slipping. Better anti-skid function helps to provide better operational control and accuracy, and prevents fingers from accidentally slipping or sliding over the target position during use.

[0037] Specifically, the design of the anti-slip stripes can increase the durability of the thumbwheel 301. The texture of the stripes can provide additional surface protection and reduce scratches and wear on the surface of the thumbwheel 301. This durability helps to extend the service life of the thumbwheel 301 and reduce the frequency of repair and replacement.

[0038] Of course, there are many types of anti-slip stripes to choose from, for example, multiple vertical stripes are set on the outer surface of the dial wheel 301 along the height direction of the dial wheel 301. For another example, multiple horizontal stripes are set on the outer surface of the dial wheel 301 along the width direction of the dial wheel 301. For another example, oblique diagonal stripes are set on the outer surface of the dial wheel 301. Or, grid stripes or diamond stripes are laid flat on the outer surface of the dial wheel 301.

[0039] refer to Figure 1 and Figure 3 A first limiting hole 105 passing through the accommodating groove 104 and a second limiting hole 106 corresponding to the through hole 102 are provided in the mounting frame 101, wherein the second limiting hole 106 is connected to the first limiting hole 105, the rotating shaft 302 is provided in the first limiting hole 105, the pressing rod 303 is provided in the second limiting hole 106, the dial wheel 301 is provided in the accommodating groove 104, and the width of the first limiting hole 105 is greater than the width of the rotating shaft 302.

[0040] The rotating shaft 302 is disposed in the first limiting hole 105, which can limit the range of motion of the rotating shaft 302 and prevent the rotating shaft 302 from exceeding the predetermined range. The pressing rod 303 is disposed in the second limiting hole 106, and is connected to the first limiting hole 105, so that the pressing rod 303 is pressed by the rotating shaft 302, ensuring that the pressing rod 303 can be stressed and displaced to contact the switch 2021. This limiting function can improve the stability and reliability of the adjustment assembly 300.

[0041] Specifically, the width of the first limiting hole 105 is greater than the width of the rotating shaft 302. This design allows the rotating shaft 302 to have a certain movable gap in the width direction of the first limiting hole 105, so that the rotating shaft 302 can be laterally displaced in the first limiting hole 105. This ensures that the rotating shaft 302 can move and displace the pressing rod 303, and finally achieve contact with the switch 2021, so that the gear of the flashlight is switched.

[0042] refer to Figures 3 to 5 A first sealing member 401 is provided between the rotating shaft 302 and the first limiting hole 105 , and a second sealing member 402 is provided between the pressing rod 303 and the second limiting hole 106 .

[0043] The first seal 401 and the second seal 402 can provide sealing performance. The first seal 401 between the rotating shaft 302 and the first limiting hole 105 can prevent dust, moisture or other impurities from entering the gap between the rotating shaft 302 and the limiting hole and entering the via hole 102, thereby protecting the normal operation of the internal components. Similarly, the second seal 402 between the pressing rod 303 and the second limiting hole 106 can prevent dust, moisture or other impurities from entering the gap between the pressing rod 303 and the limiting hole, protecting the reliability and durability of the internal mechanism.

[0044] Specifically, by providing the first seal 401 and the second seal 402, the risk of contamination and damage to the internal components can be reduced, thereby improving the maintenance performance of the adjustment component 300. The first seal 401 and the second seal 402 can prevent impurities in the external environment from entering the key components, reduce the frequency of cleaning and maintenance, and extend the service life of the adjustment component 300.

[0045] On the other hand, the presence of the first seal 401 and the second seal 402 can improve the reliability of the adjustment component 300. They can prevent the adverse factors in the external environment from affecting the internal mechanism, and maintain the stability and normal operation of the internal components. Therefore, there are many choices for the material of the seal, for example: rubber (such as nitrile rubber, silicone rubber, fluororubber, etc.), rubber seals have good elasticity and corrosion resistance, and are suitable for general sealing applications. Polytetrafluoroethylene (PTFE), PTFE is a material with excellent chemical resistance, temperature resistance and low friction coefficient. Polyurethane (PU), polyurethane has good wear resistance and oil resistance, and is suitable for some sealing applications that require wear resistance and oil resistance. Metal seals, metal seals are usually made of metal materials such as stainless steel, copper, aluminum, etc., and have good high temperature resistance and pressure resistance.

[0046] refer to Figure 3 The dial wheel 301 is provided with a center hole 3011 , and the dial wheel 301 is sleeved on the rotating shaft 302 through the center hole 3011 . The rotating shaft 302 is provided with a positioning protrusion 30221 , and the inner wall of the center hole 3011 is provided with a positioning groove 3012 corresponding to the positioning protrusion 30221 .

[0047] By providing a positioning protrusion 30221 on the rotating shaft 302 and providing a corresponding positioning groove 3012 on the inner wall of the central hole 3011 of the dial wheel 301, the accurate positioning of the dial wheel 301 and the rotating shaft 302 can be achieved through the cooperation between the positioning protrusion 30221 and the positioning groove 3012. The cooperation between the positioning protrusion 30221 and the positioning groove 3012 can ensure that the position of the dial wheel 301 on the rotating shaft 302 is fixed, and prevent it from being offset or loosened during use. This positioning function helps to keep the relative position of the dial wheel 301 and the rotating shaft 302 consistent, improves the stability of the connection between the rotating shaft 302 and the dial wheel 301, and also improves the stability of the adjustment component 300 when moving or rotating.

[0048] Specifically, the positioning protrusion 30221 and the positioning groove 3012 cooperate to achieve accurate positioning of the dial wheel 301 on the rotating shaft 302. The design of the positioning protrusion 30221 and the positioning groove 3012 can provide a reliable mutual locking mechanism, so that the rotating shaft 302 can rotate or move with the dial wheel 301, ensuring the accuracy and repeatability of the adjustment result.

[0049] Specifically, the design of the positioning protrusion 30221 and the positioning groove 3012 can enhance the stability of the entire structure. By establishing a fixed positioning connection between the rotating shaft 302 and the dial 301, the looseness and shaking of the structure can be reduced, and the stability and reliability of the entire adjustment assembly 300 can be improved. Performance degradation or failure caused by structural instability can be avoided.

[0050] refer to Figure 3 and Figure 4 The potentiometer 2011 is a hollow shaft potentiometer. The rotating shaft 302 includes a limiting section 3021, a connecting section 3022 and a receiving section 3023 which are connected in sequence. The limiting section 3021 is rotatably connected to the shell 100. The receiving section 3023 is inserted into the hollow shaft potentiometer. The positioning protrusion 30221 is provided on the connecting section 3022. The connecting section 3022 is engaged with the dial 301. A first supporting portion 3024 is provided between the connecting section 3022 and the receiving section 3023. An expanded hole is formed in the first limiting hole 105. The first sealing member 401 is placed between the first supporting portion 3024 and the bottom of the expanded hole groove.

[0051] On the one hand, by rotatably connecting the limit section 3021 with the shell 100, the limiting function of the rotating shaft 302 can be realized. The cooperation between the limit section 3021 and the shell 100 can limit the rotation range of the rotating shaft 302, ensuring that the rotating shaft 302 can only rotate within the specified range. This limiting function helps to prevent the rotating shaft 302 from exceeding the set range, avoiding misoperation or damage to the equipment. By inserting the accommodating section 3023 into the hollow shaft potentiometer, a convenient adjustment function can be achieved. As a part of the adjustment component 300, the hollow shaft potentiometer can adjust the parameters of the hollow shaft potentiometer by rotating the accommodating section 3023 to achieve fine adjustment of the circuit or equipment. This design makes the adjustment more intuitive and convenient, and improves the user's operating experience.

[0052] On the other hand, by providing a positioning protrusion 30221 on the connecting section 3022 and engaging with the positioning groove 3012 in the central hole 3011 of the dial wheel 301, the dial wheel 301 can be precisely positioned on the rotating shaft 302. The cooperation between the positioning protrusion 30221 and the dial wheel 301 can ensure that the position of the dial wheel 301 on the connecting section 3022 is fixed, preventing it from being offset or loosened during use. This precise positioning function helps to improve the accuracy and reliability of adjustment.

[0053] It should be noted that the potentiometer 2011 is a resistor element having three lead terminals and whose resistance value can be adjusted according to a certain change rule. In this embodiment, the potentiometer 2011 is a hollow shaft potentiometer, which has a hollow shaft for insertion, and a protrusion 20111 (such as Figure 3As shown). After the receiving section 3023 is inserted into the hollow shaft potentiometer, the protrusion 20111 can position the receiving section 3023 so that the receiving section 3023 and the hollow shaft are relatively engaged and fixed. When the receiving section 3023 rotates, the hollow shaft can be driven to rotate to adjust the gear position of the hollow shaft potentiometer, thereby achieving the purpose of adjusting the flashlight.

[0054] Specifically, the first supporting portion 3024 is provided between the connecting section 3022 and the accommodating section 3023 to support the first sealing member 401. An expansion hole is formed in the first limiting hole 105, and the first sealing member 401 is placed between the first supporting portion 3024 and the bottom of the expansion hole groove to achieve the sealing function of the first sealing member 401 on the first limiting hole 105, thereby preventing foreign substances from entering the interior of the rotating shaft 302. At the same time, the design of the first supporting portion 3024 can support and stabilize the first sealing member 401, thereby ensuring its sealing performance and reliability.

[0055] It should be noted that, in this embodiment, the second sealing member 401 is disposed between the rotating shaft 302 and the first limiting hole 105. The first sealing member 401 itself has a certain deformation capability, so when the rotating shaft 302 is pressed to trigger the switch 2021, the connecting section 3022 of the rotating shaft 302 can move in a certain horizontal direction to make the limiting section 3021 contact the switch 2021. At the same time, when the rotating shaft 302 is pressed, the force-bearing area of ​​the rotating shaft 302 is mainly concentrated in the limiting section 3021 at the upper end of the rotating shaft 302, and the rotating shaft 302 will deflect with the accommodating section 3023 as the rotation center, and there is almost no lateral displacement at the accommodating section 3023, which will not affect the cooperation between the accommodating section 3023 and the hollow rotating shaft, so it can be ensured that the potentiometer 2011 is not affected when the rotating shaft 302 is pressed, and the limiting section 3021 can trigger the switch 2021 to operate.

[0056] refer to Figure 3 and Figure 5 The pressing rod 303 includes a contact section 3031 and a pressing section 3032 that are connected to each other. The contact section 3031 is in contact with the limiting section 3021. The pressing section 3032 is formed with a second supporting portion 3033 and a limiting groove 3034 that are adjacently arranged. The limiting groove 3034 is arranged on the side of the second supporting portion 3033 facing the contact section 3031. The second sealing member 402 is arranged in the limiting groove 3034. The elastic member 500 is sleeved on the pressing section 3032. One end of the elastic member 500 is in contact with the side of the second supporting portion 3033 facing the pressing section 3032, and the other end is in contact with the through hole 102.

[0057] By abutting the abutment section 3031 against the limiting section 3021, the pressure of the rotating shaft 302 can be transmitted to the pressing rod 303, so that the pressing rod 303 moves and contacts the switch 2021. The cooperation between the abutment section 3031 and the limiting section 3021 can also limit the movement range of the pressing rod 303, ensuring that the pressing rod 303 can only perform a pressing operation within a specified range. Such abutment and limiting function helps prevent misoperation or damage to the device.

[0058] Specifically, the second sealing member 402 and the elastic member 500 are respectively arranged on opposite sides of the second supporting portion 3033 , so as to avoid mutual influence between the second sealing member 402 and the elastic member 500 , and ensure that the pressing process of the pressing rod 303 is stable and smooth.

[0059] Specifically, by providing the second supporting portion 3033 and the limiting groove 3034 on the pressing section 3032, and providing the second sealing member 402 in the limiting groove 3034, the second sealing member 402 can be supported and the second limiting hole 106 can be sealed. The second sealing member 402 is placed in the limiting groove 3034 to prevent foreign substances from entering the second limiting hole 106 or even the through hole 102. At the same time, one side of the second supporting portion 3033 can support and stabilize the second sealing member 402, and the other side can limit and support the elastic member 500 to ensure the reliability of the elastic member 500.

[0060] Specifically, by arranging an elastic member 500 on the pressing section 3032, the pressing rod 303 can actively restore to its initial position through the elastic member 500 after being subjected to force to press the switch 2021, so that the pressing rod 303 has elastic force as a whole. This elastic force helps to provide operational stability and operational feedback of the pressing rod 303, so that the user can better perceive the force and changes of the pressing operation.
