[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] like Figures 1 to 11As shown, this embodiment provides a dual rotary switch headlamp body 100, which includes a multi-light source lens 1, a power control box 2, a light source adjustment switch 3, and a brightness adjustment switch 4. The multi-light source lens 1 is equipped with a main light source 11 and multiple auxiliary light sources 12. The multi-light source lens 1 is mounted on the power control box 2, which includes a control circuit board 23. The main light source 11 and the multiple auxiliary light sources 12 are all electrically connected to the control circuit board 23. The light source adjustment switch 3 includes a rotating ring 31 and a first magnet 32. The rotating ring 31 is rotatably mounted on the power control box 2, and the first magnet 32 ​​is located at one end of the rotating ring 31 near the power control box 2. The control circuit board 23 is equipped with multiple first Hall sensors 231, the number of which is the same as the number of auxiliary light sources 12. The rotating ring 31 can drive the first magnet 32 ​​to rotate to a position opposite to the first Hall sensors 231, thereby allowing different light source modes to be switched by rotating the rotating ring 31. The brightness adjustment switch 4 includes a knob 41 and a connector 42. The connector 42 is located at one end of the knob 41 near the power control box 2. An encoder 233 is also provided on the control circuit board 23. The connector 42 can be connected to the encoder 233, and the brightness of different modes of light sources can be adjusted by rotating the knob 41.

[0047] It should be noted that a Hall sensor is a component capable of detecting changes in a magnetic field. When a magnet approaches a Hall sensor, the Hall sensor senses the change in magnetic field strength and converts it into an electrical signal output. In this embodiment, multiple first Hall sensors 231 are associated with multiple auxiliary light sources 12 one by one. By moving the first magnet 32 ​​to face different first Hall sensors 231, the corresponding auxiliary light source 12 is triggered to operate, thereby achieving the switching of different light source modes.

[0048] An encoder is a sensor that converts mechanical quantities such as rotation angle and speed into continuous electrical signals. In this embodiment, after connector 42 is inserted into encoder 233, rotating knob 41 converts the rotation of knob 41 into a series of continuous electrical pulses (or phase-changing signals). The pulse signals output by encoder 233 are transmitted to the main control module (such as a microcontroller) of the lamp. After receiving the pulse signals, the main control module converts them into linearly changing PWM control signals, and finally achieves stepless brightness adjustment by adjusting the driving power of the light source.

[0049] Both the first Hall sensor 231 and the encoder 233 are existing technologies, and their specific structures will not be described in detail here.

[0050] The dual rotary switch headlamp body 100 provided in this embodiment uses two independent rotary adjustment switches to control the light source mode and brightness respectively. Specifically, different light source modes can be switched by rotating the rotating ring 31, and the brightness of different light source modes can be steplessly adjusted by rotating the knob 41, so that users can easily switch different light source modes and brightness according to the usage scenario. Moreover, the rotary adjustment switch is more reliable and durable than the traditional button switch.

[0051] Optionally, such as Figure 2 and Figure 5 As shown, in this embodiment, the multi-source lens 1 is provided with four auxiliary light sources 12, and the control circuit board 23 is provided with four first Hall sensors 231, thereby enabling the switching of four different light source modes. It is understood that in some other embodiments, the number of auxiliary light sources 12 and first Hall sensors 231 can be set according to actual needs, as long as the number of both is the same, and there is no limitation here.

[0052] Furthermore, such as Figure 6 As shown, an anti-slip structure 312 is provided on the outer circumferential surface of the rotating ring 31, which facilitates the user to rotate the rotating ring 31.

[0053] like Figure 3 and Figure 4 As shown, the power control box 2 also includes a front housing 21, a rear cover 22, a battery compartment 24, and a battery 25. The front housing 21 and the rear cover 22 are detachably connected, forming a receiving cavity between them. The control circuit board 23, the battery compartment 24, and the battery 25 are all housed within this cavity. A first clearance hole 211 is provided on the front end plate of the front housing 21. The control circuit board 23 is located near the first clearance hole 211, allowing the main light source 11 and multiple auxiliary light sources 12 to pass through the first clearance hole 211 and connect electrically to the control circuit board 23. A insertion hole 212 is also provided on the front housing 21, specifically on the side end plate of the front housing 21. The connector 42 can connect to the encoder 233 through the insertion hole 212. The battery compartment 24 is located between the control circuit board 23 and the back cover 22. The battery 25 is located inside the battery compartment 24. The battery 25 is electrically connected to the control circuit board 23 through the battery compartment 24, thereby supplying power to the control circuit board 23.

[0054] Optionally, such as Figure 3 and Figure 4As shown, in this embodiment, the front housing 21 has a slot 215, and the rear cover 22 has a protrusion 221. The protrusion 221 can engage with the slot 215, thereby achieving the snap-fit ​​fixation between the front housing 21 and the rear cover 22. The structure of the protrusion 221 and the slot 215 is simple and facilitates quick assembly and disassembly of the front housing 21 and the rear cover 22 by the user. It is understood that in some other embodiments, the front housing 21 and the rear cover 22 can also adopt other types of structures to achieve a detachable connection, such as a screw connection, which is not limited here.

[0055] like Figure 3 As shown, the battery compartment 24 is also provided with a shell coating 26. By providing the shell coating 26, on the one hand, it can absorb external impacts and reduce the impact of vibration on the internal battery 25 and circuit, reducing the risk of the battery 25 becoming loose, having poor contact, or the circuit being damaged. On the other hand, the shell coating 26 will fit tightly with the battery compartment 24, filling gaps and helping to improve the sealing of the battery compartment 24, preventing rainwater and dust from entering the interior and protecting the battery 25 and circuit safety.

[0056] like Figure 3 and Figure 6 As shown, the front housing 21 is provided with multiple limiting grooves 213. The light source adjustment switch 3 also includes a first ball plunger 33. The first ball plunger 33 is located at one end of the rotating ring 31 near the front housing 21 and is spaced apart from the first magnet 32. The first ball plunger 33 can move into the limiting groove 213, and when the first ball plunger 33 moves into the limiting groove 213, the first magnet 32 ​​can move to the position opposite to the first Hall sensor 231.

[0057] Specifically, multiple first Hall sensors 231 are arranged in an arc with uniform intervals on the control circuit board 23, and multiple limiting grooves 213 are arranged in a circumferentially with uniform intervals outside the first clearance hole 211. The projection of the rotating ring 31 on the front housing 21 coincides with the circumference formed by the multiple limiting grooves 213. The projection of the rotating ring 31 on the control circuit board 23 coincides with the arc formed by the multiple first Hall sensors 231. The arc length between any two adjacent limiting grooves 213 is equal to the arc length between any two adjacent first Hall sensors 231. Each first Hall sensor 231 has a corresponding limiting groove 213. The first ball-head plunger 33 and... The arc length between the first magnets 32 is an integer multiple of the arc length between any two adjacent limiting grooves 213. Optionally, in this embodiment, it is twice the arc length. Therefore, when the first ball-head plunger 33 is located within a limiting groove 213 and the first magnet 32 ​​is opposite to a first Hall sensor 231, when the clockwise rotating ring 31 moves the first ball-head plunger 33 into the adjacent next limiting groove 213, the first magnet 32 ​​can move to a position opposite to the next first Hall sensor 231. When the counter-clockwise rotating ring 31 moves the first ball-head plunger 33 into the adjacent previous limiting groove 213, the first magnet 32 ​​can move to a position opposite to the previous first Hall sensor 231. By setting the limiting grooves 213, it is easier for users to accurately switch between different light source modes.

[0058] like Figure 3 and Figure 6 As shown, the control circuit board 23 is also equipped with two second Hall sensors 232. One second Hall sensor 232 controls the headlight to turn on, and the other second Hall sensor 232 controls the headlight to turn off. The light source adjustment switch 3 also includes a second magnet 34 and a second ball plunger 35. The second magnet 34 and the second ball plunger 35 are also arranged at one end of the rotating ring 31 near the front housing 21, and are spaced apart from each other. The second ball plunger 35 can also move into the limiting groove 213, and when the second ball plunger 35 moves into the limiting groove 213, the second magnet 34 can move to the position opposite to the second Hall sensor 232.

[0059] It should be noted that the second Hall sensor 232 is also existing technology, and its specific structure and working principle will not be described in detail here.

[0060] Specifically, two second Hall sensors 232 are arranged in an arc-shaped interval on the control circuit board 23. The projection of the rotating ring 31 on the control circuit board 23 coincides with the arc formed by the two second Hall sensors 232. The arc length between the two second Hall sensors 232 is equal to the arc length between any two adjacent limiting grooves 213, and each of the two second Hall sensors 232 has a corresponding limiting groove 213. The arc length between the second magnet 34 and the second ball plunger 35 is equal to the arc length between any two adjacent limiting grooves 213. Therefore, when the second ball plunger 35 is located in the corresponding open limiting groove 213, the second magnet 34 is opposite to the second Hall sensor 232 that controls the opening; when the second ball plunger 35 is located in the corresponding closed limiting groove 213, the second magnet 34 is opposite to the second Hall sensor 232 that controls the closing. This configuration allows the user to easily switch the headlamp on and off.

[0061] Optionally, such as Figure 3 As shown, in this embodiment, a fluorescent sticker 27 is also provided on the front housing 21. By providing the fluorescent sticker 27, the headlamp can be quickly found or identified in the dark environment, avoiding loss and improving safety when using it at night.

[0062] like Figure 1 , Figure 8 and Figure 9 As shown, a connector 5 is provided on the front housing 21. The connector 5 is roughly in the shape of a water bottle cap. The connector 5 includes a mounting part 51 and a fixing part 52. The mounting part 51 is a ring-shaped structure. The multi-light source lens 1 is disposed on the inner ring side of the mounting part 51. The rotating ring 31 is rotatably sleeved on the outer ring of the mounting part 51. The fixing part 52 is disposed at one end of the mounting part 51 near the front housing 21. A second clearance hole 521 is provided on the fixing part 52. The second clearance hole 521 can communicate with the first clearance hole 211. The main light source 11 can pass through the second clearance hole 521 and the first clearance hole 211 in sequence, and then be electrically connected to the control circuit board 23. The fixing part 52 is used to install the connector 5 on the front housing 21.

[0063] Optionally, such as Figure 3 and Figure 9As shown, in this embodiment, the front housing 21 also has two first mounting holes 214, and the connector 5 has two second mounting holes 522. The first mounting holes 214 and the second mounting holes 522 are provided in a one-to-one correspondence, and the first mounting holes 214 can communicate with the second mounting holes 522. Therefore, by setting fasteners to pass through the first mounting holes 214 and the second mounting holes 522, the connector 5 can be fixed to the front housing 21. It is understood that in some other embodiments, the connector 5 and the front housing 21 can also be fixedly connected by other means, such as snap-fit, which is not limited here. It is also understood that in other embodiments, the connector 5 and the front housing 21 can be an integral structure, which is not limited here.

[0064] Furthermore, to ensure that the rotating ring 31 can rotate stably on the connecting member 5, such as... Figure 6 and Figure 11 As shown, in this embodiment, the rotating ring 31 is provided with an inner ring flange 311, and the mounting part 51 is provided with an outer ring step 511. The outer ring step 511 can form a groove with the front housing 21, and the inner ring flange 311 can be rotatably disposed in the groove. Through this arrangement, not only is the rotation of the rotating ring 31 more stable, but the rotating ring 31 can also be axially limited to prevent it from falling off the connecting member 5.

[0065] like Figure 8 and Figure 11 As shown, a first sealing element 9 is provided between the multi-light source lens 1 and the connector 5, and a second sealing element 10 is provided between the connector 5 and the front housing 21. By providing the first sealing element 9 to seal the gap between the multi-light source lens 1 and the connector 5, and by providing the second sealing element 10 to seal the gap between the connector 5 and the front housing 21, external rainwater and dust can be prevented from entering the interior of the dual rotary switch headlamp body 100, thereby avoiding contamination of the main light source 11 and the auxiliary light source 12, and further protecting the battery 25 and circuit safety.

[0066] Optionally, such as Figure 8 and Figure 11 As shown, in this embodiment, an auxiliary light plate 6 is also provided between the multi-source lens 1 and the connector 5. Multiple auxiliary light sources 12 are electrically connected to the auxiliary light plate 6, and the auxiliary light plate 6 is electrically connected to the control circuit board 23. By setting the auxiliary light plate 6, the blind spots of the main light source 11 can be eliminated, and the light can be softened to avoid strong light glare. It is suitable for scenarios such as close-range operation and nighttime warning, making the lighting more flexible and comprehensive.

[0067] It should be noted that the auxiliary light plate 6 is existing technology, and its specific structure and working principle will not be described in detail here.

[0068] Furthermore, to facilitate the mounting of the multi-source lens 1 and the auxiliary light plate 6 onto the connector 5, such as... Figure 9 As shown, in this embodiment, an inner ring step 53 is also provided between the mounting part 51 and the fixing part 52, wherein the auxiliary light plate 6 is disposed on the fixing part 52, and the multi-source lens 1 is disposed on the inner ring step 53. This arrangement facilitates the installation and positioning of the multi-source lens 1 and the auxiliary light plate 6.

[0069] like Figure 8 and Figure 11 As shown, a lens holder 7 is also provided between the multi-source lens 1 and the auxiliary light plate 6. The lens holder 7 is used to position the multi-source lens 1. Specifically, as shown... Figure 2 and Figure 8 As shown, in this embodiment, both the main light source 11 and the auxiliary light source 12 are conical protruding structures. The mirror holder 7 is provided with multiple concave conical groove structures, and both the main light source 11 and the auxiliary light source 12 can be placed in the corresponding conical groove structures. By setting the mirror holder 7, displacement of the multi-light source lens 1 can be prevented, ensuring the lighting effect. At the same time, it can also protect the edge of the multi-light source lens 1, help improve the sealing performance, and reduce the assembly difficulty of the multi-light source lens 1.

[0070] It should be noted that the mirror holder 7 is existing technology, and its specific structure and working principle will not be described in detail here.

[0071] like Figure 8 and Figure 11 As shown, a pressure ring 8 is provided at the end of the connector 5 away from the front housing 21. The inner diameter of the pressure ring 8 is smaller than the diameter of the multi-light source lens 1, and the outer diameter of the pressure ring 8 is larger than the outer diameter of the rotating ring 31. By setting the pressure ring 8, the axial movement of the multi-light source lens 1 and the rotating ring 31 is further restricted, thereby ensuring that the dual rotary switch headlamp body 100 can provide safe and stable illumination.

[0072] The dual rotary switch headlamp body 100 provided in this embodiment uses two independent rotary adjustment switches to control the light source mode and brightness respectively. Specifically, different light source modes can be switched by rotating the rotating ring 31, and the brightness of different light source modes can be steplessly adjusted by rotating the knob 41, so that users can easily switch different light source modes and brightness according to the usage scenario. Moreover, the rotary adjustment switch is more reliable and durable than the traditional button switch.

[0073] like Figure 12As shown, this embodiment also provides a headlamp, which includes a headband 200, a headband clip 300, and a dual rotary switch headlamp body 100 as described above. The headband clip 300 is mounted on the dual rotary switch headlamp body 100, and the headband 200 is threaded through the headband clip 300. When using this headlamp, the user can wear the dual rotary switch headlamp body 100 on their head through the headband 200, use one hand to rotate the rotating ring 31 to control the switch of the dual rotary switch headlamp body 100, and rotate the rotating ring 31 to switch different light source modes. The other hand can rotate the knob 41 to steplessly adjust the brightness of different light source modes. The headlamp has a simple overall structure and is easy to operate, meeting the lighting needs of different occasions.

[0074] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
