Description

Technical Field

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

[0002] In dark environments (such as nighttime maintenance, outdoor camping, and emergency repairs), where both hands need to be used simultaneously, traditional handheld lighting devices have limitations in their usability. To address this, head-mounted lights (such as miner's lamps and headlamps) have been introduced to free up the user's hands. These lights allow the illumination area to move with the head and the user's field of vision, greatly improving ease of use. Most head-mounted lights are equipped with a headband to secure them to the user's head.

[0003] However, most head-mounted lights are quite large, and wearing them on the head can cause significant weight and fatigue for users over a long period of time. Utility Model Content

[0004] In view of this, the present invention provides a headlamp to solve the problem that the existing headlamp is too large, which causes a significant burden when worn on the head and easily leads to user fatigue after prolonged use.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figure 1-10 As shown, a headlamp includes a lamp body 1 and a connecting component. The lamp body 1 has a length of no more than 6cm, a width of no more than 2.5cm, and a height of no more than 2.5cm. The front end of the lamp body 1 is provided with a light-emitting component 6 for illumination. The connecting component is detachably connected to the lamp body 1. The connecting component is configured to detachably fix the lamp body 1 to the support structure of a wearable accessory. Designing the lamp body 1 to be a compact shape with a maximum size of no more than 6cm not only effectively controls the materials used in the headlamp, reduces the overall weight of the headlamp, and reduces the burden when wearing the headlamp, but also makes it easier to store and carry the headlamp. When the support structure is glasses, the headlamp is first placed on the outside of the temple of the glasses, and the direction of the light is consistent with the direction of the glasses. Then, the lamp body 1 is detachably connected to the outside of the temple of the glasses through the connecting component, so as to replace the headlamp to help the user achieve nighttime illumination. It can be worn without feeling and will not cover the head skin, which is conducive to heat dissipation of the head.

[0036] In one embodiment, the dimensions of the lamp body 1 after being connected to the annular cover 64 are 2.4-6cm in length, 1.28-2.5cm in width, and 1.28-2.5cm in height.

[0037] In one embodiment, the dimensions of the lamp body 1 after being connected to the annular cover 64 are 2.4-5cm in length, 1.28-2cm in width, and 1.28-2cm in height.

[0038] In one embodiment, the dimensions of the lamp body 1 after being connected to the annular cover 64 are 2.4-4cm in length, 1.28-1.5cm in width, and 1.28-1.5cm in height.

[0039] In one embodiment, the dimensions of the lamp body 1 after being connected to the annular cover 64 are 2.4-3cm in length, 1.28-1.3cm in width, and 1.28-1.3cm in height.

[0040] In this embodiment, the dimensions of the lamp body 1 after being connected to the annular cover 64 are preferably 2.4cm in length, 1.28cm in width, and 1.28cm in height, and it is made of aluminum or aluminum alloy or similar lightweight material. Thanks to its small size and lightweight material, the weight of the headlamp can be limited to less than 6 grams. Compared with the existing headlamps that weigh hundreds of grams, the headlamp of this application can truly achieve imperceptible wearing and effectively improve the wearing comfort. The side wall of the lamp body 1 is provided with heat dissipation grooves along its circumference in order to increase the heat dissipation area of ​​the lamp body 1 and improve the heat dissipation efficiency of the headlamp.

[0041] Specifically, the supporting structure includes hat brims, eyeglass frames, or headdresses.

[0042] Example 1:

[0043] like Figure 1 , Figure 8 , Figure 10 As shown, the connecting component is a spring clip 100. The end of one arm of the spring clip 100 is detachably connected to the rear end of the lamp body 1. In this embodiment, the end of the arm and the rear end of the lamp body 1 can be detachably connected by any means such as plugging or snapping. The orientation of the spring clip 100 is perpendicular to the illumination direction of the headlamp. The user can use the spring clip 100 to hold the temple of the glasses or the brim of the hat and fix the headlamp on the outside of the temple of the glasses or the brim of the hat for use, so that the headlamp can be used to connect to various load-bearing structures.

[0044] Specifically, the inner front end of each of the two clamping arms is provided with a clamping groove 101 for engaging the temple. In one embodiment, the two clamping grooves 101 have different widths to accommodate two different thicknesses of temples.

[0045] Example 2:

[0046] like Figure 2-3 As shown, the connecting assembly further includes a base 3 and a strap 7. A limiting shaft 24 is provided on the first side wall of the base 3, and a buckle 23 is provided on the second side wall of the base 3. The end of the strap 7 is sleeved on the limiting shaft 24. Several locking holes 71 are evenly distributed along the length direction on the front end of the strap 7. The buckle 23 can be locked into any locking hole 71. The inner side wall of the strap 7 and the side wall of the base 3 together form a constraint channel a through which the temples of the eyeglasses pass. By selecting different locking holes 71 and buckles 23 to lock into, the cross-sectional area of ​​the constraint channel a can be adjusted to accommodate the binding of temples of different diameters, ensuring that the headlamp is stably bound to the temples.

[0047] In this embodiment, a through first positioning groove 35 is provided on the first side wall of the base 3 along the width direction of the base 3, and a through second positioning groove 36 is provided on the second side wall of the base 3 along the width direction of the base 3. The limiting shaft 24 is provided on the inner wall of the first positioning groove 35, and the buckle 23 is provided on the inner wall of the second positioning groove 36. When the headlamp is tied to the temple of the mirror by the strap 7, the strap 7 will be in a taut state. At this time, the rear end of the strap 7 will be engaged in the first positioning groove 35, and the front end of the strap 7 will be engaged in the second positioning groove 36. The first positioning groove 35 and the second positioning groove 36 form a limit on the strap 7, preventing the strap 7 from shifting in the length direction of the base 3, making the structure of the constraint channel a more stable, thereby ensuring the installation stability of the headlamp on the temple.

[0048] Example 3:

[0049] like Figure 4-7 As shown, the connecting assembly further includes a base 3, a strap 7, a clamping block 81, and an elastic element 82. A limiting shaft 24 is provided on the first side wall of the base 3, and a spring-loaded groove 25 is provided on the second side wall of the base 3. A through-hole 26 is also provided on the base 3, penetrating both sides and intersecting with the spring-loaded groove 25. The clamping block 81 is slidably or partially slidably connected within the spring-loaded groove 25. An avoidance opening 83 is provided on the clamping block 81 that can connect with the through-hole 26. The through-hole 26 and the avoidance opening 83 can form a passageway b. The end of the strap 7 passes through the passageway b and is sleeved on the limiting shaft 24. The elastic element 82 is located at the bottom of the spring-loaded groove 25 and is used to drive the clamping block 81 to slide, forcing the avoidance opening 83 to offset from the through-hole 26. The strap 7 is clamped within the passageway b by the squeezing action between the inner wall of the avoidance opening 83 and the inner wall of the through-hole 26. The inner wall of the strap 7 and the side wall of the base 3 together form a constraint channel a through which the temple of the eyeglasses passes. By changing the clamped area at the front end of the strap 7, the cross-sectional area of ​​the constraint channel a can be adjusted. In use, first press down or pull the exposed end of the clamping block 81 so that the clearance opening 83 slides with the clamping block 81 and aligns with the through opening 26. Then, the front end of the strap 7 passes through the passage channel b, and then the control force on the clamping block 81 is released. At this time, the elastic element 82 will drive the clamping block 81 to reset, forcing the clearance opening 83 to be offset from the through opening 26. The corresponding part of the strap 7 in the passage channel b is clamped by the squeezing action of the inner wall corner of the clearance opening 83 and the inner wall corner of the through opening 26, thereby limiting the movable end of the strap 7. The user can slide the strap 7 along the passage channel b to adjust the clamped part of the strap 7, thereby changing the cross-sectional area of ​​the constraint channel a.

[0050] In this embodiment, the elastic element 82 is a spring, and the clamping block 81 has a receiving cavity that opens toward its bottom wall. The spring is sleeved in the receiving cavity, with one end of the spring extending out of the receiving cavity and abutting against the bottom wall of the spring pressure groove 25, and the other end of the spring abutting against the inner wall of the receiving cavity.

[0051] Furthermore, the front end of the strap 7 has a dimension in at least one direction that is larger than the dimension in the corresponding direction of the through-hole 26. This is to restrict the front end of the strap 7 from passing through the through-hole 26 (not shown in the figure) when it is used, so that the front end of the strap 7 cannot pass through the through-passage b. This serves to prevent the front end of the strap 7 from coming loose and to ensure that the strap 7 is stably attached to the temple of the glasses.

[0052] Example 4:

[0053] Furthermore, the connecting assembly includes a base 3 and a strap 7. A limiting shaft 24 is provided on the first side wall of the base 3. The end of the strap 7 is sleeved on the limiting shaft 24. The inner side of the front end of the strap 7 can be detachably connected to the second side wall of the base 3 via Velcro. The hook side of the Velcro is placed on the second side wall of the base 3, and the velvet side is distributed along the length of the strap 7 on its inner side (not shown in the figure). The inner side wall of the strap 7 and the side wall of the base 3 together form a constraint channel a through which the temple of the eyeglasses passes. The cross-sectional area of ​​the constraint channel a can be adjusted by changing the connection area at the front end of the strap 7.

[0054] Specifically, the strap 7 is made of rubber or silicone to increase the frictional resistance between the strap 7 and the temple, thereby improving the grip of the strap 7 on the temple.

[0055] In this embodiment, the combined length of the lamp body 1 and the connecting component is no more than 3.5cm, the width is no more than 1.9cm, and the height is no more than 1.9cm. It is compact in shape and lightweight, and can be worn without being felt.

[0056] In one embodiment, the lamp body 1 has a built-in battery that powers the light-emitting component 6. The battery can be a dry cell battery or a rechargeable battery (not shown in the figures).

[0057] Furthermore, a straight wall 33 is connected between the first and second sidewalls of the base 3. The straight wall 33 can form a constraint channel a with the inner sidewall of the strap 7. Since a considerable number of glasses are made of acetate, the cross-section of their temples is mostly rectangular or waist-shaped. When the headlamp is tied to the outside of such temples, with the strap 7 tightened, the straight wall 33 will be tightly pressed against the outer sidewall of the temple. The temple can provide a certain limit and support for the headlamp through the straight wall 33, preventing the headlamp from swinging around the temple and making the headlamp installation more stable. A rubber pad 34 is laid on the straight wall 33. When the lamp body 1 is tied to the temple and the straight wall 33 is tightly pressed against the outer sidewall of the temple, the outer sidewall of the temple will squeeze the rubber pad 34, thereby increasing the frictional resistance between the lamp body 1 and the temple through the rubber pad 34, improving the anti-slip ability between the two and improving the connection stability.

[0058] Furthermore, the rear end of the lamp body 1 is connected to a quick-release structure 4, and a snap-fit ​​notch 31 is provided on the side wall of the base 3 facing away from the constraint channel a. The base 3 is preferably made of plastic material with a certain degree of elasticity. The snap-fit ​​notch 31 is set in the same direction as the constraint channel a. The outline of the quick-release structure 4 matches the snap-fit ​​notch 31 and is detachably snapped into the snap-fit ​​notch 31.

[0059] Furthermore, the cross-section of the snap-fit ​​notch 31 is circular, and the width of its side opening is smaller than its inner diameter. A protrusion 32 is provided at the side opening of the snap-fit ​​notch 31, and a groove 42 corresponding to the protrusion 32 is provided on the quick-release structure 4. In this embodiment, the cross-section of the snap-fit ​​notch 31 is circular, and the width of its side opening is smaller than its inner diameter. A protrusion 32 is provided at the side opening of the snap-fit ​​notch 31, and a groove 42 is provided on the quick-release structure 4 corresponding to the protrusion 32. The quick-release structure 4 can be snapped by pressing... The side opening of the notch 31 is inserted into the notch 31 and is detachably connected to the base 3, so that the user can remove the quick-release structure 4 and the lamp body 1 separately, avoiding the need to reconnect the base 3 and the temple. When the quick-release structure 4 is inserted into the notch 31, a part of the quick-release structure 4 will be engaged in the side opening of the notch 31, and the protrusion 32 will be engaged with the groove 42, thereby limiting the radial, circumferential and axial displacement of the quick-release structure 4 in the notch 31, and fixing it in the notch 31.

[0060] Furthermore, the rear end of the lamp body 1 is provided with a ball head 52, and the front end of the quick-release structure 4 is provided with a ball seat 41. The ball head 52 is snapped into the ball seat 41. When in use, the user can move the lamp body 1 so that the lamp body 1 can swing and position itself through the ball joint structure to change the illumination angle of the light-emitting component 6 relative to the direction of the glasses, and flexibly adjust the lighting area to meet different lighting needs of the user, such as following the viewing angle for illumination, or illuminating the ground in front of the user below the viewing angle.

[0061] Specifically, the quick-release structure 4 is made of plastic, the lamp body 1 is made of aluminum, and the lens 63 is made of acrylic plastic. This design ensures structural strength while effectively reducing the overall weight of the headlamp, minimizing its impact on eyeglasses, facilitating a seamless wearing experience, and enhancing the user experience.

[0062] Furthermore, the light-emitting component 6 includes an LED 61, a condenser cup 62, a lens 63, and an annular cover 64. The lamp body 1 has a mounting cavity 51 that opens towards its front end. The LED 61 is disposed on the bottom wall of the mounting cavity 51. The condenser cup 62 is fitted inside the mounting cavity 51, and its narrow end surrounds the LED 61. The lens 63 is disposed at the opening of the mounting cavity 51. The annular cover 64 is fixed to the front end of the lamp body 1 and presses the LED 61, the condenser cup 62, and the lens 63 into the mounting cavity 51 through its inner ring structure. The light emitted by the LED 61 is refracted and focused by the cup wall of the condenser cup 62 and then emitted through the lens 63, forming an illuminated area within the field of vision of the eyeglass wearer.

[0063] Specifically, a sealing ring 65 is provided between the inner ring of the annular cover 64 and the periphery of the lens 63. The sealing ring 65 closes the gap between the two to improve the airtightness of the mounting cavity 51, prevent moisture or impurities from entering, and extend the service life of the lamp bead 61.

[0064] Furthermore, the headlamp also includes a wire 91 and a flexible cable tie 92. One end of the wire 91 passes through the rear end of the lamp body and is electrically connected to the light-emitting component. The cable tie 92 has a cable channel through which the power supply wire 91 passes and a socket cavity 93 for the temple to pass through. The cable tie 92 is sleeved on the wire 91 through the cable channel. The cross-section of the socket cavity 93 has a major axis and a minor axis, and the cross-section can be waist-shaped, rectangular, or rhomboid to fit the contour of the temple. The cable tie 92 is sleeved on the temple through the socket cavity 93. The cable tie 92 helps the wire 91 to run along the direction of the temple, which not only improves the integration of the headlamp device and the glasses and enhances the appearance, but also protects the connection end of the wire 91 to the lamp body 1, preventing the end from easily breaking due to long-term bending or external pulling, thus extending the service life of the headlamp device.

[0065] Specifically, both the quick-release structure 4 and the ball head 52 have wiring holes for the power supply wire 91 to pass through. The wire 91 passes through the wiring hole of the quick-release structure 4, the inner cavity of the ball seat 41, and the wiring hole of the ball head 52 in sequence, and finally enters the mounting cavity 51 to be electrically connected to the lamp bead 61.

[0066] like Figure 2 As shown, in this embodiment, the wire harness 92 is a hollow structure with both ends through it, and its inner cavity forms a wire harness channel. The wire harness 92 is sleeved on the wire 91 through the wire harness channel, and the wire harness channel also serves as a connection channel for the temple to be sleeved.

[0067] In one embodiment, the wire harness 92 is fixed to the wire 91 by adhesive bonding (not shown in the figure).

[0068] In one embodiment, the wire harness 92 is integrally formed with the wire 91 (not shown in the figures).
