Description

Technical Field

[0001] This utility model belongs to the field of headlamp technology, and in particular relates to a multifunctional magnetic headlamp. Background Technology

[0002] In outdoor activities, night work, rescue operations, and underground mining operations, headlamps are often required for illumination. Traditional headlamps, with their structural design and functionality, struggle to meet the growing needs of users and suffer from the following shortcomings:

[0003] Traditional headlamps typically use a single, fixed headlamp structure that cannot be replaced or rotated, making it difficult to adapt to changing ambient lighting conditions and limiting the flexibility of headlamp use.

[0004] When the headlamp's battery is depleted, the user needs to remove the entire headlamp to charge it, which not only affects the smoothness of continuous use but also causes some inconvenience, especially in situations where long-term lighting is required, such as outdoors. The traditional headlamp's functional design can no longer meet the needs of continuous lighting.

[0005] The headband design also has shortcomings in terms of wearing comfort and ease of operation. Traditional headlamps mostly use a fixed strap or D-ring buckle, which makes the operation of adjusting the tightness cumbersome, time-consuming and troublesome, and it is difficult to quickly adjust the headband length to adapt to different head sizes or emergency situations.

[0006] Traditional split-type headlamps do not have internal batteries and cannot be removed for separate use. The headlamp and battery are connected by external wires, resulting in a visually cluttered and unattractive appearance. They also affect the adjustment of the headband and limit the flexibility of headlamp use.

[0007] Against this backdrop, the design of this product incorporates several innovations to address the aforementioned problems. Utility Model Content

The lateral damping pins 604 are rotatably connected to the headlamp part 7. That is, when the magnetic attraction part 6 is magnetically assembled onto the lamp holder 1, the metal pillars 605 are in contact with the elastic metal contacts 102, so that the headlamp part 7 forms a conductive electrical connection with the elastic metal contacts 102 and the metal connecting piece through the lateral damping pins 604.

[0045] Further reference Figure 6-7As shown, the headlamp unit 7 includes a lamp housing 701, a lens cover 702, a bracket 703, a second rechargeable battery 704, a button 705, a flexible circuit board 706, a lamp assembly 709, a contact spring 707, and a second charging interface 708. The bracket 703 is fixedly installed inside the lamp housing 701, and the second rechargeable battery 704 is arranged inside the bracket 703. The flexible circuit board 706 is laid on the outside of the bracket 703, and the lamp assembly 709 is mounted on the flexible circuit board 706.

The flexible circuit board 706 is electrically connected to the second rechargeable battery 704, the button 705, the lamp assembly 709, and the second charging interface 708. Both ends of the second charging interface 708 are connected to the lateral damping pins 604 on both sides through the contact spring 707.

[0046] Furthermore, the headband component 3 includes an elastic connecting strap 301 and an adjustment component 8. Both the left and right sides of the power supply housing 2 have strap holes 201. One end of the elastic connecting strap 301 passes through the strap hole 201 and then folds back to connect to the power supply housing 2, forming a length-adjustable telescopic closed-loop strap 302. The telescopic closed-loop strap 302 and the elastic connecting strap 301 are movably connected by the adjustment component 8. The elastic connecting strap 301 contains several wavy, coated copper wires, with both ends of the coated copper wires connected to corresponding elastic metal contacts 10. 2 is electrically connected to the power supply component 5. The adjustment component 8 includes a traction block 801, a roller 802, a traction belt 803, and Velcro.

The traction block 801 is provided with a movable roller 802 on one side of the slot 804. The telescopic closed loop belt 302 passes through the slot 804 and forms a rolling telescopic connection with the roller 802. The inner side of the traction belt 803 is provided with Velcro, which is used to detachably bond to the outer side of the elastic connecting belt 301.

[0047] In this embodiment, to facilitate wearing and use, a rolling adjustment component 8 is designed. Pulling the traction belt 803 drives the roller 802 to roll, so that the telescopic closed loop belt 302 is in a rolling elongation state relative to the roller 802, which in turn drives the elastic connecting belt 301 to a contraction state. This allows the elastic connecting belt 301 to quickly scale up to the user's head and be fastened by Velcro. The entire headband component 3 can be adapted and worn flexibly in one step, and the operation is simple.

[0048] It should be noted that the reference Figure 12As shown, the elastic connecting strip 301 is provided with several wavy coated fine copper wires. The elastic connecting strip 301 is made of braided material, and the coated fine copper wires can be hidden inside the braided material, so that the elastic connecting strip 301 has a slight elasticity and elongation. At the same time, the coated fine copper wires are also in a stretching state with a straightening tendency, so as to achieve better design and use requirements.

[0049] Further reference Figure 8-11 As shown, the power supply component 5 includes a first circuit board 202, a first charging interface 203, a single-ended bipolar battery 204, a first indicator light 205, and a first transparent lampshade 206. The first circuit board 202 is fixedly installed inside the power supply housing 2. The first charging interface 203 is located at the bottom of the power supply housing 2. A through battery mounting hole is located at the rear of the power supply housing 2, and a removable single-ended bipolar battery 204 is installed in the battery mounting hole. Several first indicator lights 205 are provided on the first circuit board 202. The first transparent lampshade 206 is located on the upper surface of the power supply housing 2, and the first indicator lights 205 are located below the first transparent lampshade 206. The first circuit board 202 is electrically connected to the first charging interface 203, the single-ended bipolar battery 204, and the first indicator lights 205. The power supply component 5 is an independently powered component. It can be used to charge its own single-ended bipolar battery 204 and store electricity. It can also be used to connect to the headlamp 7 via insulated thin copper wire to provide power to the headlamp 7 and extend its usage time.

[0050] Furthermore, the power supply housing 2 is provided with a conductive spring 208 for connecting to the single-ended bipolar battery 204. The conductive spring 208 is electrically connected to the first circuit board 202, and the first circuit board 202 is electrically connected to the coated fine copper wire. The power supply housing 2 is provided with a detachable screw cap 2010 on one side of the battery assembly hole. The screw cap 2010 is provided with a coiled compression spring 2011 for pressing against the single-ended bipolar battery 204.

[0051] Specifically, the inner wall of the screw cap 2010 is provided with several arc-shaped protrusions 2012, and the arc-shaped protrusions 2012 are provided with arc-shaped recesses 2013. The power supply housing 2 is provided with an arc-shaped groove 2014 on the outer side of the battery assembly hole, and the arc-shaped groove 2014 is provided with an arc-shaped buckle 2015. The arc-shaped protrusions 2012 are rotated into the arc-shaped groove 2014, so that the arc-shaped buckle 2015 and the arc-shaped recesses 2013 are fastened together.

[0052] Furthermore, the lamp assembly 709 includes a COB lamp 7091 disposed at the front end, a red lamp 7092 and a white lamp 7093 located on one side of the COB lamp 7091, with the red lamp 7092 located directly below the white lamp 7093. The COB lamp 7091 is the main light source and is relatively bright, while the red lamp 7092 and the white lamp 7093 are secondary light sources. When the main light source and the secondary light source are lit together, the maximum lumen value is 600 lm, which can be used as a high beam, a low beam, and for nighttime use.

[0053] Specific operating principle:

[0054] First, the headlamp component 4 can be used as an independent lighting unit. It can be removed or separated from the lamp holder 1, allowing the headlamp component 4 to be used independently. The second rechargeable battery 704 provides power to the flexible circuit board 706, the second rechargeable battery 704, the button 705, the lamp assembly 709, the second charging interface 708, etc. For example, in narrow and difficult-to-illuminate places, the headlamp component 4 can be directly removed and held by hand for illumination, which is simple and convenient.

[0055] Secondly, the headlamp 7 is magnetically connected to the lamp holder 1 via the magnetic part 6, allowing the headlamp 7 to rotate relative to the magnetic part 6 at a certain angle as needed, facilitating adjustment of the illumination angle. The conduction method formed after the magnetic connection is as follows: output of the single-head bipolar battery 204 --- insulated fine copper wire --- elastic metal contact 102 (one side) --- metal post 605 --- lateral damping pin 604 --- contact spring 707 (one side) --- second charging interface 7 08---Flexible circuit board 706---Second charging interface 708---Contact spring 707 (other side)---Lateral damping pin 604---Metal post 605---Elastic metal contact 102 (other side)---Insulated fine copper wire--Back to single-head bipolar battery 204, thus forming a long-lasting power supply circuit when using magnetic lighting. Even if the single-head bipolar battery 204 is depleted, it can still be switched to use for independent lighting of headlamp component 4. It should be noted that the flexible circuit board 706 has a built-in control circuit detection setting. When magnetically attached, the flexible circuit board 706 detects the connection of the single-head bipolar battery 204. The single-head bipolar battery 204 serves as a power output terminal to power the COB LED beads 7091, red LED beads 7092, and white LED beads 7093. The second rechargeable battery 704 stores electricity for charging and remains in a usable state with power after the headlamp component 4 is removed. When removed and not magnetically attached, the flexible circuit board 706 does not detect the connection of the single-head bipolar battery 204, and the headlamp component 4 is used for independent lighting.

[0056] In summary, this utility model provides a multi-functional magnetic headlamp. The magnetic design allows for a magnetic connection between the headlamp component 4 and the lamp holder 1. The modular design facilitates easy assembly and disassembly, making it convenient to replace the headlamp component 4. The magnetic part 6 is rotatably connected to the headlamp part 7, allowing the user to rotate the headlamp part 7 to the desired angle to meet multi-angle lighting needs. This solves the problems of traditional headlamps not being usable independently, having a fixed angle, and being difficult to adjust, making lighting more flexible and convenient. The headlamp part 7 is equipped with an independent second rechargeable battery 704, eliminating the need for users to remove the entire magnetic headlamp for charging each time. Even if the second rechargeable battery 704 in the headlamp part 7 is depleted, it can be recharged using a second rechargeable battery. The second charging port 708 connects to the first charging port 203 of the power supply component 5 to provide timely power and extend battery life. This solves the problems of insufficient battery life and unsightly external wire connections in traditional headlamps, and avoids interruptions in use due to charging. It provides reliable battery life for long-term outdoor activities. The headband component 3 uses a combination of rollers 802 and Velcro. Users only need to pull the traction strap 803 to make the rollers 802 roll, which quickly adjusts the length of the telescopic closed loop strap 302. This allows for quick adjustment of the elastic connecting strap 301 to fit the user's head shape and improve wearing comfort and ease of adjustment. It greatly simplifies the cumbersome adjustment methods of traditional fixing straps or D-ring buckles, making wearing and adjustment faster and more accurate.
