[0043] Reference Figure 1~Figure 5, which is the first embodiment of the utility model, proposes
[0044] A headlamp, comprising:
[0045] Main body 100;
[0046] The lamp head 200 is movably arranged on the main body 100;
[0047] The fixing belt 300 is disposed on the main body 100 and is used to fix the main body 100 to the head.
[0048] In this embodiment, in order to solve the problem that the angle adjustment of the lamp head in the related art is usually limited and the user may not get enough light in some cases, the main body 100 of the headlamp is made of light and strong materials, with a compact structure and easy to wear. The main body 100 is provided with a power supply device, a circuit control module and a heat dissipation system to ensure that the headlamp can emit light continuously and stably. The lamp head 200 is designed to be movable and connected to the main body 100 through a rotating joint or a slide rail structure, so that the lamp head 200 can be flexibly adjusted at multiple angles according to the user's viewing angle requirements. The lamp head 200 is equipped with an efficient LED light source with adjustable brightness and is equipped with an optical lens to achieve spotlighting or floodlighting. The two sides or the rear of the headlamp main body 100 are equipped with fixing straps 300, which are preferably made of elastic and comfortable materials to adapt to different head circumferences and ensure comfort when wearing. The fixing belt 300 is connected to the main body 100 through an adjustable buckle or Velcro. The user can fasten the fixing belt 300 to the head as needed, so as to stably fix the headlamp on the head, so that the headlamp can always maintain a stable lighting state in scenes such as outdoor activities and night work, without affecting the freedom of head movement. In this embodiment, the lamp head 200 is designed to be mobile, and the lamp head 200 can be moved when needed to ensure that the user gets enough light in certain situations.
[0049] Furthermore, the main body 100 has an installation space 110 and further includes:
[0050] A fixing column 400 is disposed in the installation space 110;
[0051] A first rotating member 500 is rotatably disposed on the fixed column 400;
[0052] The connecting rope 600 has one end disposed on the first rotating member 500 and the other end disposed on the lamp holder 200 . The connecting rope 600 is wound around the first rotating member 500 , and the lamp holder 200 is moved and disposed on the main body 100 through the connecting rope 600 .
[0053] In this embodiment, a dedicated installation space 110 is provided inside the main body 100, and the space is intended to accommodate and support the movement and rotation mechanism of the lamp holder 200. A fixed column 400 is provided in the installation space 110, and the fixed column 400 is fixed inside the main body 100, serving as a fulcrum for the rotation and movement of the lamp holder 200. A first rotating member 500 is rotatably provided on the fixed column 400, and the rotating member has a degree of rotational freedom and can rotate 360 degrees around the fixed column 400. One end of the connecting rope 600 is fixed to the first rotating member 500, and the other end is fixed to the lamp holder 200. The connecting rope 600 is wound around the first rotating member 500 to form a reel-like effect. When the first rotating member 500 is rotated, the connecting rope 600 will be wound or unfolded with the rotation of the rotating member, thereby realizing the up and down movement and angle adjustment of the lamp holder 200 on the main body 100. The lamp head 200 is connected to the main body 100 via a connecting rope 600. By pulling or loosening the connecting rope 600, or rotating the first rotating member 500, the lamp head 200 can be flexibly moved and positioned on the main body 100, so that the user can quickly and conveniently adjust the illumination direction and illumination height of the headlamp according to actual needs, thereby improving the convenience and practicality of using the headlamp.
[0054] Further, the fixed column 400 has a clamping gap 410, and the first rotating member 500 includes:
[0055] The rotating cylinder 510 is rotatably mounted on the fixed column 400 and has a mounting cavity 520. The mounting cavity 520 is sleeved on the fixed column 400. One end of the connecting rope 600 is mounted on the rotating cylinder 510 and is used to drive the rotating cylinder 510 to rotate.
[0056] One end of the first elastic member 530 is clamped in the clamping gap 410 , and the other end is clamped on the rotating cylinder 510 . The first elastic member 530 is used to provide a force for restoring the rotating cylinder 510 .
[0057] In this embodiment, in the structure of the main body 100, a clamping gap 410 is specially provided on the fixed column 400 for installing the first elastic member 530 to realize the automatic reset function of the rotating cylinder 510. The first rotating member 500 mainly includes a rotating cylinder 510 part, which is rotatably arranged on the fixed column 400 and forms a mounting cavity 520 therein. There is a small rotating cavity in the mounting cavity 520, and the rotating cavity and the mounting cavity 520 are connected. The rotating cavity and the fixed column 400 are in close contact to ensure that the rotating cylinder 510 rotates smoothly on the fixed column 400. One end of the connecting rope 600 is fixed on the rotating cylinder 510. When the connecting rope 600 is pulled or loosened, the rotating cylinder 510 can be driven to rotate around the fixed column 400, thereby adjusting the position of the lamp head 200. At the same time, the first elastic member 530 is cleverly designed and installed in the clamping gap 410 of the fixed column 400, one end of which is clamped and fixed in the clamping gap 410, and the other end is connected to the rotating cylinder 510. When the rotating cylinder 510 is rotated by external force, when the external force is removed, the first elastic member 530 will generate a restoring force due to its own elastic properties, pushing the rotating cylinder 510 back to its original position, so that the lamp head 200 can automatically return to the preset default position when no external force is applied, thereby improving the convenience and stability of the headlamp.
[0058] Furthermore, it also includes:
[0059] The guide cylinder 700 is disposed in the installation space 110 , and the connecting rope 600 passes through the guide cylinder 700 . The guide cylinder 700 is used to prevent the connecting rope 600 from being entangled.
[0060] In this embodiment, in order to prevent the connecting rope 600 from getting tangled when automatically winding, a guide cylinder 700 is added in the installation space 110 inside the main body 100 structure. The guide cylinder 700 is fixed in an appropriate position. Its main function is to provide guidance for the connecting rope 600 to prevent the connecting rope 600 from getting tangled when the lamp head 200 moves and rotates. In specific implementation, one end of the connecting rope 600 is fixed on the rotating cylinder 510, and the lifting and angle adjustment of the lamp head 200 are achieved by winding on the rotating cylinder 510, while the other end of the connecting rope 600 is fixed on the lamp head 200. In the process of extending from the lamp head 200 to the rotating cylinder 510, the connecting rope 600 will pass through the guide cylinder 700 and shuttle in an orderly manner through the cavity inside the guide cylinder 700, ensuring that when the lamp head 200 moves arbitrarily, the rope will not be tangled due to random swinging, thereby effectively improving the convenience and safety of the headlamp operation.
[0061] Furthermore, it also includes:
[0062] The rotating wheel 800 is rotatably disposed on the rotating cylinder 510 and has a plurality of protrusions 810 arranged at intervals along the circumference. The protrusions 810 have a first clamping end 820, a connecting end 830, and a second clamping end 840 which are sequentially connected and disposed;
[0063] The second rotating member 900 has a first end 910, a second end 920 and a third end 930 arranged in sequence. The second end 920 is rotatably set on the main body 100. A first arc segment 940 is provided between the first end 910 and the second end 920, and a second arc segment 950 is provided between the second end 920 and the third end 930. After the rotating wheel 800 rotates counterclockwise, a second clamping end 840 drives the second rotating member 900 to rotate counterclockwise by abutting against the first end 910. The connecting end 830 abuts against the first arc segment 940 and the second arc segment 950 in sequence. The connecting end 830 drives the second rotating member 900 to rotate clockwise by abutting against the third end 930. The connecting end 830 slides out of the second arc segment 950. After the rotating wheel 800 rotates clockwise, one connecting end 830 abuts against the first end 910, driving the second rotating member 900 to rotate counterclockwise. The other first clamping end 820 is clamped and set on the third end 930.
[0064] In this embodiment, a rotatable rotating wheel 800 is added to the rotating cylinder 510 inside the main body 100 structure, and a plurality of structures with protrusions 810 are evenly spaced along the circumferential direction on the rotating wheel 800. Each protrusion 810 is composed of three continuous parts, namely a first clamping end 820, a connecting end 830 and a second clamping end 840, which are connected and arranged together in sequence. The second rotating member 900 is designed as a special linkage member, which has a first end 910, a second end 920 and a third end 930 arranged in sequence, and the second end 920 is rotatably connected to the main body 100 structure. A first arc segment 940 is formed between the first end 910 and the second end 920 of the second rotating member 900, and a second arc segment 950 is formed between the second end 920 and the third end 930.
[0065] When the connecting rope is pulled out, the rotating wheel 800 rotates counterclockwise, and the second clamping end 840 of one of the protrusions 810 will first abut against the first end 910 of the second rotating member 900, and the second rotating member 900 will be pushed to rotate counterclockwise through this contact. As the rotating wheel 800 continues to rotate, the connecting end 830 of the protrusion 810 will slide through the first arc segment 940 and the second arc segment 950 in sequence, and when it reaches the end of the second arc segment 950, it will abut against the third end 930 of the second rotating member 900, driving the second rotating member 900 to rotate clockwise. At this time, the connecting end 830 will slide out of the second arc segment 950, completing a complete interactive action. Conversely, when the connecting rope is retracted, the rotating wheel 800 rotates clockwise, and one of the connecting ends 830 will first abut against the first end 910 of the second rotating member 900, and the second rotating member 900 will be pushed to rotate counterclockwise again. As the rotating wheel 800 rotates clockwise, the first clamping end 820 of the other protrusion 810 will be timely clamped to the third end 930 of the second rotating member 900, thereby locking the position of the second rotating member 900. Through this precise mechanical linkage design, the headlamp cannot be retracted at will after being pulled out during operation, and can only be retracted manually.
[0066] Furthermore, the second rotating member 900 is rotatably and slidably disposed on the rotating cylinder 510, and the second rotating member 900 includes:
[0067] A sliding rod 960, slidably disposed on the main body 100;
[0068] A lever 970 is rotatably disposed on the sliding rod 960, and a first end 910, a second end 920 and a third end 930 are all located on the lever 970;
[0069] The second elastic member 980 has one end disposed on the main body 100 and the other end disposed on the lever 970 . The second elastic member 980 is used to provide a force for the lever 970 to approach the rotating wheel 800 .
[0070] In this embodiment, the second rotating member 900 can not only rotate on the main body 100, but also slide and adjust on the rotating cylinder 510. The second rotating member 900 is mainly composed of a sliding rod 960 and a lever 970. The sliding rod 960 is slidably arranged along the main body 100. The lever 970 is rotatably arranged on the sliding rod 960. When the rotating wheel 800 rotates, the corresponding end point of the lever 970 will interact with the protrusion 810 on the rotating wheel 800, so that the headlight can be fixedly extended when the length of the headlight is different. In order to facilitate the recovery of the lamp holder 200, the present solution designs the sliding rod 960 as a structure that slides on the main body 100. By pulling the sliding rod 960 outward, the sliding rod 960 is away from the rotating wheel 800, and the lever 970 cannot limit the protrusion 810. Due to the action of the first elastic member 530, the connecting rope 600 will drive the lamp holder 200 to automatically recover. After the recovery is completed, the sliding rod 960 is released, and the second elastic member 980 drives the sliding rod 960 to reset, ensuring that when there is no external force, the lever 970 can automatically reset to a state close to the rotating wheel 800, so as to be ready to effectively interact with the protrusion 810 on the rotating wheel 800 at any time, thereby improving the sensitivity and reliability of the headlamp operation.
[0071] Furthermore, the main body 100 has a snap-fitting hole 120 , which is in communication with the installation space 110 , and the lamp holder 200 is snap-fitted and disposed in the snap-fitting hole 120 .
[0072] In this embodiment, in order to realize the automatic resetting of the lamp holder 200, a snap-in hole 120 is designed on the main body 100. After the connecting rope 600 is recovered, it drives the lamp holder 200 to be reset. A guiding slope is designed on the lamp holder 200. When the lamp holder 200 approaches the snap-in hole 120, due to the effect of the guiding slope, the lamp holder 200 will be snapped into the snap-in hole 120, thereby realizing the automatic resetting of the lamp holder 200.
[0073] Furthermore, the main body 100 has a first mounting hole 130 and a second mounting hole 140, and the first mounting hole 130 and the second mounting hole 140 both have an opening 150. The fixing belt 300 has a fourth end 310 and a fifth end 320, and the fourth end 310 and the fifth end 320 are respectively clamped and arranged in the first mounting hole 130 and the second mounting hole 140 through the opening 150.
[0074] The main body 100 further has a third mounting hole 160 , and the fixing belt 300 has a sixth end 330 , which is disposed in the third mounting hole 160 .
[0075] The main body 100 has an arc-shaped end surface 340 , and the arc-shaped end surface 340 is used to abut against the forehead.
[0076] In this embodiment, two mounting holes are provided on the structure of the main body 100, namely, a first mounting hole 130 and a second mounting hole 140, and both mounting holes are designed with openings 150, in order to facilitate the insertion and fixation of the fixing belt 300. The two ends of the fixing belt 300, namely, the fourth end 310 and the fifth end 320, are respectively fixed in the holes through the openings 150 of the first mounting hole 130 and the second mounting hole 140, so as to ensure the stable connection between the fixing belt 300 and the main body 100, and also facilitate the user to adjust the length of the fixing belt 300 according to the size of the head circumference. In addition, a third mounting hole 160 is also provided on the main body 100, and the sixth end 330 of the fixing belt 300 is inserted and fixed in the hole, so as to further disperse the force of the fixing belt 300 and improve the stability and comfort of wearing the headlamp. One side of the main body 100 is designed as an arc-shaped end surface 340, which fits the contour of the human forehead. When the headlamp is worn, the arc-shaped end surface 340 can naturally and comfortably abut the user's forehead, reducing the discomfort caused by long-term wearing, and also ensuring that the headlamp can still maintain the best lighting position during intense exercise or shaking. This design fully considers the user experience and improves the convenience and comfort of using the headlamp.
