Description

Technical Field

[0001] This utility model relates to the field of outdoor lighting technology, and in particular to a dual-segment flashlight switch and flashlight. Background Technology

[0002] Flashlights have become an indispensable lighting tool for outdoor activities. The on / off function and function adjustment of a flashlight mainly rely on button operation. When the user presses a button on the flashlight, the button transmits data to the circuit board, thereby realizing the flashlight's on / off state and the switching of brightness or mode.

[0003] Currently, flashlights on the market mainly employ two button control methods: a single-button design and a multi-button combination design. Single-button flashlights have limited functional expandability, making it difficult to meet users' diverse needs for brightness adjustment, signal flashing, and special lighting modes. While multi-button combinations can achieve more functions, the layout of multiple buttons increases operational complexity, especially in dark environments where users must repeatedly fumble around to locate the desired button. Furthermore, because multi-button structures generally require more space on the flashlight's surface, the flashlight body needs to be extended to accommodate the additional buttons, increasing overall size and impacting portability.

[0004] Therefore, existing technologies still need improvement. Utility Model Content

Detailed Implementation

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] In outdoor adventure scenarios, flashlights play a crucial role as essential lighting equipment. Their working principle is as follows: when the user presses the flashlight's function button, mechanical contact generates an electrical signal, which is transmitted to the control circuit board. This signal, through a preset program, enables core functions such as turning the light on and off, adjusting brightness, and switching modes. However, current flashlight designs on the market have some limitations: single-button designs restrict functionality, while multiple-button layouts complicate operation.

[0033] Based on this, the embodiments of this application disclose a dual-stage flashlight with on / off switch, such as... Figure 1 and Figure 2As shown, the dual-stage flashlight switch includes a control circuit board 100, a button 200, and a conductive component. The control circuit board 100 is provided with a switch 110 and a conductive component 120. The button 200 is located directly above the switch 110. The button 200 is hollow, forming a first mounting cavity 210. The conductive component includes a first elastic element 310, a second elastic element 320, and a floating conductive element 330. The first elastic element 310 is arranged around the button 200 to support the button 200. The floating conductive element 330 is disposed in the first mounting cavity 210 and at least partially extends out of the first mounting cavity 210. The second elastic element 320 is disposed inside the first mounting cavity 210. One end of the second elastic element 320 abuts against the inner wall of the first mounting cavity 210, and the other end abuts against the floating conductive element 330.

[0034] This dual-stage flashlight switch can be used in flashlights, achieving function switching through segmented tactile feedback provided by a single button 200. In actual use, the switch 110 and the conductive element 120 are fixedly mounted on the control circuit board 100, and the floating conductive element 330 is movably positioned between the conductive element 120 and the button 200; one end of the second elastic element 320 is fixed to the inner wall of the button 200, and the other end is fixed to the floating conductive element 330; the first elastic element 310 is arranged around the button 200 to support the button 200.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, when button 200 is not pressed, the first elastic element 310 lifts the entire button 200. At this time, there is a certain distance between the floating conductive element 330 and the conductive element 120, so there is no connection between the floating conductive element 330 and the conductive element 120. When button 200 is pressed, the first elastic element 310 is squeezed, button 200 moves down, the floating conductive element 330 contacts the conductive element 120 and becomes connected. At this time, the control circuit board 100 forms a circuit through the conductive element 120 and the floating conductive element 330. When button 200 is pressed, the first elastic element 310 continues to compress and move downward (towards switch 110). At this time, the conductive element 120 presses against the floating conductive element 330, causing the floating conductive element 330 to move upward (towards away from switch 110). The floating conductive element 330 presses against the second elastic element 320 located in the first mounting cavity 210. At the same time, button 200 descends to its maximum depth and contacts switch 110 located on control circuit board 100, thereby opening and closing switch 110.

[0036] Therefore, the segmented tactile feedback provided by the first elastic element 310, the second elastic element 320, and the floating conductor 330 corresponds to different usage modes and brightness levels of the flashlight with varying tactile force. It is evident that this embodiment allows for flashlight function switching with a single button, optimizing the switching process and reducing the space occupied by the button on the flashlight surface, making the flashlight more compact and portable. Specifically, when the user lightly presses button 200, they can switch the flashlight's brightness or mode. During this process, the first elastic element 310 is compressed, while the second elastic element 320 remains uncompressed, allowing for easy function switching with a light press. When the user presses button 200 harder, the flashlight is switched on and off. In this case, the first elastic element 310 is compressed, the conductor 120 abuts against the floating conductor 330, and the conductor 120 pushes the floating conductor 330 upwards, compressing the second elastic element 320 as well. Therefore, the user needs to apply greater pressure to complete this operation.

[0037] In this embodiment, each time the flashlight user lightly presses button 200, the electrical signal generated by the mechanical contact is transmitted to the control circuit board 100. The control circuit board 100 adjusts the flashlight's brightness according to a preset program. When the user needs to adjust the flashlight's brightness or switch modes, they can lightly press the conductive element multiple times in succession to achieve functions such as brightness adjustment or mode switching through the number of mechanical contacts.

[0038] Before the flashlight leaves the factory, the relationship between the number of button presses 200 and the preset program on the control circuit board 100 can be preset. The number of button presses 200 can be 1, 2, 3, 4, or even more. In one embodiment, the flashlight brightness is preset to three levels: pressing button 200 once provides the brightest illumination; pressing button 200 twice provides medium illumination; and pressing button 200 three times provides the dimmest illumination. Pressing button 200 firmly turns the flashlight on and off.

[0039] In one embodiment, different electrical signals can be generated by pressing the button 200 for varying durations. These signals are transmitted to the control circuit board 100, which can then adjust the flashlight's brightness according to a preset program. Specifically, a long press of the button 200 results in the dimst flashlight brightness, while a short press results in the brightest. A hard press of the button 200 lowers it to its maximum depth and contacts the switch 110, thus turning the flashlight on and off.

[0040] In this embodiment, as Figure 2As shown, the conductive element 120 is configured as a conductive post, and there are two conductive posts, namely the first conductive post 121 and the second conductive post 122. The first conductive post 121 and the second conductive post 122 are distributed on both sides of the switch 110 at intervals. When the button 200 is pressed lightly, the button 200 moves downward, the first elastic element 310 is compressed, and the floating conductive element 330 abuts against the two conductive posts. The control circuit board 100 forms a circuit through the two conductive posts and the floating conductive element 330.

[0041] In another embodiment disclosed in this utility model, such as Figure 4 As shown, the button 200 includes a first pressing member 220 and a second pressing member 230; the first pressing member 220 is hollow and forms a first mounting cavity 210; the outer side wall of the first pressing member 220 extends outward to form an annular outer edge 221; the annular outer edge 221 abuts against the first elastic member 310; one end of the second pressing member 230 is connected to the first pressing member 220, and the other end is used to abut against the switch 110.

[0042] Specifically, the first pressing member 220 has a first mounting cavity 210 inside, the cross-sectional shape of the first pressing member 220 is a regular "T" shape, the cross-sectional shape of the second pressing member 230 is an inverted "T" shape, and the first pressing member 220 is connected to the second pressing member 230; the floating guide member 330 is annular in shape, sleeved at the connection position of the first pressing member 220 and the second pressing member 230, and one side of the floating guide member 330 abuts against the second pressing member 230.

[0043] When the first pressing member 220 is not under force, the first elastic member 310 supports the first pressing member 220, so that the floating conductor 330 and the conductive post maintain a certain distance, and there is no conductivity between the floating conductor 330 and the conductive post. When the first pressing member 220 is gently pressed, the first pressing member 220 moves down, and the first elastic member 310 is compressed. The floating conductor 330 contacts the two conductive posts. At this time, the control circuit board 100 forms a circuit through the two conductive posts and the floating conductor 330. When the first pressing member 220 is pressed down heavily, the first pressing member 220 moves down, and the first elastic member 310 continues to compress. At this time, the conductive post presses against the floating conductor 330, and the floating conductor 330 compresses the second elastic member 320. At this time, the second pressing member 230 descends to its maximum depth and presses the switch 110 set on the control circuit board 100, thereby realizing the on / off of the flashlight switch.

[0044] In this embodiment, the floating conductor 330 is arranged in a ring between the first pressing member 220 and the second pressing member 230. The second pressing member 230 provides a certain supporting force to the floating conductor 330, preventing the floating conductor 330 from descending on its own and contacting the conductive post to form a circuit, thus ensuring circuit safety and reliability of the flashlight circuit system during operation.

[0045] In one implementation, such as Figure 2 and Figure 4 As shown, the first mounting cavity 210 is an annular cavity; a screw hole 222 is provided at the center of the first pressing member 220; the end of the second pressing member 230 connected to the first pressing member 220 is provided with a thread 231; the second pressing member 230 is inserted into the screw hole 222 and screwed into the first pressing member 220. An annular floating conductor 330 is arranged around the connection position of the first pressing member 220 and the second pressing member 230, and the first pressing member 220 and the second pressing member 230 are screwed together, making the vertical distance from the second pressing member 230 to the switch 110 adjustable, reducing the frequency of failures and lowering maintenance costs.

[0046] Specifically, in actual use, the end of the floating conductor 330 extending out of the annular cavity abuts against the second pressing member 230. This design ensures that when the first pressing member 220 is lightly pressed, the floating conductor 330 can abut against the conductive post; simultaneously, when the first pressing member 220 is pressed hard, the path of the floating conductor 330 moving upward to compress the second elastic member 320 is extended, allowing the user to receive clear force feedback. Different force feedbacks correspond to different flashlight usage modes and brightness, thus helping the user quickly locate the desired mode and brightness. In this way, multiple functions can be switched without multiple buttons, reducing the cumbersome function switching of existing flashlights and improving the convenience of flashlight use.

[0047] In this embodiment, as Figure 4 As shown, the control circuit board 100 is also provided with a cover 130; the cover 130 is an insulating component, one end of the first elastic member 310 abuts against the annular outer edge 221 on the first pressing member 220, and the other end abuts against the cover 130. With this design, when the first pressing member 220 is pressed lightly or heavily, the first elastic member 310 can be effectively compressed, and at the same time, the first elastic member 310 is isolated from the control circuit board 100 to avoid short circuit.

[0048] In one embodiment, the floating conductor 330 is recessed inward on the side opposite to the floating conductor 330 to form a groove; wherein, one end of the second elastic member 320 abuts against the inner wall of the first pressing member 220, and the other end abuts against the groove, ensuring that when the first elastic member 310 is pressed hard, the floating conductor 330 moves upward under the action of the conductive member 120 and compresses the second elastic member 320, so that the flashlight user receives different force feedback.

[0049] Based on the above embodiments, such as Figure 1 and Figure 2As shown, this utility model also discloses a dual-segment flashlight, including a power supply 400, a housing assembly 500, a light source assembly 600, and a dual-segment flashlight switch as described in any one of the above. The button 200 is movably disposed at the end of the housing assembly 500; the housing assembly 500 includes an upper housing 510 and a lower housing 520; the upper housing 510 and the lower housing 520 are connected to form a second mounting cavity; the power supply 400, the control circuit board 100, and the conductive component are all disposed in the second mounting cavity.

[0050] Specifically, the power supply 400 is disposed in the second mounting cavity, and its two ends are connected to the control circuit board 100 and the light source assembly 600, respectively. The button 200 extends at least partially outside the second mounting cavity for easy pressing by the user, thereby switching the flashlight function. When the button 200 is pressed lightly or firmly, the electrical signal generated by the mechanical contact is transmitted to the control circuit board 100, which outputs according to a preset program to adjust the on / off state of the light source assembly 600 or the illumination brightness.

[0051] Furthermore, in some embodiments, the upper housing 510 and the lower housing 520 can be an integral structure, that is, the upper housing 510 and the lower housing 520 are integrally fitted onto the battery, control circuit board 100, and conductive components; similarly, the upper housing 510 and the lower housing 520 can also be designed as a detachable structure, that is, the upper housing 510 and the lower housing 520 are connected and fixed by connectors, such as screws, or by clips. The shape of the upper housing 510 and the lower housing 520 is not limited in this application, and can be cylindrical or columnar, etc. In this embodiment, the light source assembly 600 is disposed on the housing assembly 500 at the end opposite to the button 200; the light source assembly 600 includes an indicator light 610 and a front cover 620; the indicator light 610 is electrically connected to the power supply 400; the front cover 620 is fitted onto the second mounting cavity at the end near the indicator light 610.

At this time, preset lighting levels can be switched sequentially by repeatedly pressing the button; when the button is pressed heavily, the first elastic element continues to compress, and at this time, the conductive element pushes the floating conductive element to squeeze the second elastic element, while the button contacts the switch, realizing the opening and closing of the switch.
