[0026] Example

[0027] like Figure 1-4As shown, this embodiment provides a head-mounted headlamp comprising a head base 1 and a lamp head 2. The head base 1 is intended to be worn on a user's head, and the lamp head 2 is intended to emit light. The lamp head 2 includes a mounting shell 21 hinged to the upper surface of the head base 1. Specifically, the mounting shell 21 and the head base 1 are connected by a hinge seat and a pin, allowing the lamp head 2 to rotate about the pin, thereby changing the angle of illumination of the light. The mounting shell 21 is embedded with a heat dissipation bracket 22. The heat dissipation bracket 22 is made of aluminum or an aluminum alloy material with good thermal conductivity. The mounting shell 21 is made of plastic. During processing, the mounting shell 21 and the heat dissipation bracket 22 are made of plastic-coated aluminum injection molding. The top of the heat dissipation bracket 22 is bolted to an LED light board 23. The surface of the LED light board 23 is welded with LED lamp beads 24. The LED light board 23 and the LED lamp beads 24 emit light directly. The outer side of the mounting shell 21 is provided with a lampshade 25. The mounting shell 21 is a circular tubular structure, and the inner wall of the lampshade 25 can be along the mounting shell 21. The outer wall of the lampshade 25 is arranged to slide up and down, and the top of the lampshade 25 is covered with a flat lens 26. The flat lens 26 is a new optical flat metalens in the prior art. The flat metalens is a flat optical device with a surface micro-nano structure that modulates the phase of the incident light and converges the image. It is manufactured in large quantities through semiconductor chip technology. It has the characteristics of small thickness, light weight, simple structure, and low cost. By sliding the lampshade 25 back and forth on the mounting shell 21, the flat lens 26 can be moved close to or away from the LED lamp bead 24, thereby adjusting the illumination effect of the light and realizing the switching between high beam and low beam.

[0028] Specifically, a gland 27 is detachably connected to the top of the mounting housing 21. The mounting housing 21 and the gland 27 are fixed together by a threaded connection. A light-transmitting opening is provided in the middle of the gland 27, corresponding to the LED lamp beads 24, to prevent the gland 27 from blocking the light from the LED lamp beads 24. The bottom of the lampshade 25 is provided with a folded edge 251 that bends toward the mounting housing 21 and abuts against the bottom of the gland 27. The gland 27 has two left and right parts. First, the gland 27 presses the LED light board 23 tightly, improving the structural strength of the LED light board 23 and preventing it from loosening. Second, the gland 27 acts as a limiter for the lampshade 25. When the lampshade 25 moves upward and reaches the upper part of the mounting housing 21, the folded edge 251 contacts the gland 27, preventing the lampshade 25 from moving further, preventing it from separating from the mounting housing 21 and thus limiting its travel.

[0029] Furthermore, at least one first sealing groove is formed on the outer side of the pressure cover 27, and a first sealing ring 271 is embedded in the first sealing groove. The first sealing ring 271 is arranged to abut against the lampshade 25. In this embodiment, there are two first sealing grooves and two first sealing rings 271. The first sealing ring 271 has two functions. First, the first sealing ring 271 acts as a waterproofing agent, preventing external liquid from entering the interior of the lamp head 2 through the gap between the lampshade 25 and the mounting shell 21 and contaminating the LED lamp board 23 and the LED lamp beads 24. Second, the first sealing ring 271 increases the friction between the lampshade 25 and the mounting shell 21, so that after the user moves the position of the lampshade 25, the lampshade 25 will not slide easily, which can ensure that the lampshade 25 can remain in the designated position and prevent the light irradiation position from changing during use.

[0030] Furthermore, at least one second sealing groove is defined on the inner side of the gland 27. A second sealing ring 272 is embedded in the second sealing groove and abuts against the outer wall of the mounting shell 21. In this embodiment, there are two second sealing grooves and two second sealing rings 272. The second sealing rings 272 fill the gap between the gland 27 and the mounting shell 21, preventing external liquid from entering the interior of the lamp holder 2 through the gap between the gland 27 and the mounting shell 21, thereby improving the waterproof performance.

[0031] Specifically, the top cover of the lampshade 25 is provided with a transparent pressing plate 28, which can be made of glass. The pressing plate 28 is used to shield the plane lens 26 to prevent external dust and the like from contaminating the plane lens 26. The top of the lampshade 25 is threadedly connected to a cover 29, the bottom of which is arranged to abut against the surface of the pressing plate 28, and the lower surface of the pressing plate 28 is arranged to abut against the upper surface of the plane lens 26. The cover 29 presses the pressing plate 28 and the plane lens 26 together, thereby achieving the installation of the plane lens 26 and the pressing plate 28 and preventing the plane lens 26 and the pressing plate 28 from loosening.

[0032] Specifically, the head base 1 is internally provided with a control circuit board 11 and a battery 13. The control circuit board 11 is electrically connected to the battery 13 and is integrated with an on / off button 12 embedded in the surface of the head base 1. The control circuit board 11 integrates a circuit module for controlling the on / off of the LED lamp beads 24 and a power module, thereby controlling the operation of the headlight. Pressing the on / off button 12 turns the LED lamp beads 24 on or off, and the battery 13 is used to provide power for the LED lamp beads 24.

[0033] Furthermore, a wire conduit 18 is fixedly connected to the surface of the header 1. The ends of the wire conduit 18 are respectively connected to the header 1 and the mounting shell 21. The control circuit board 11 is connected to the LED light board 23 via internal wires passing through the wire conduit 18. In this embodiment, the connection between the wire conduit 18, the header 1, and the mounting shell 21 is waterproofed to improve waterproof performance.

[0034] Furthermore, the control circuit board 11 is integrated with an indicator light 14, which is embedded in the surface of the head base 1. There are multiple indicator lights 14, and the higher the brightness of the LED lamp beads 24, the more indicator lights 14 will light up. By pressing the switch button 12 multiple times, the brightness of the LED lamp beads 24 can be changed. For example, pressing it once turns on the LED lamp beads 24 and the brightness is at the lowest brightness. Continue pressing to gradually increase the brightness. After the brightness reaches the maximum, continue pressing to turn off the LED lamp beads 24.

[0035] Furthermore, a data interface 15 and a charging interface 16 are embedded in the bottom of the headrest 1, and the data interface 15 and the charging interface 16 are respectively electrically connected to the control circuit board 11. The data interface 15 is used to connect the data line to update the data of the chip of the control circuit board 11, and the charging interface 16 is used to connect the charging line to charge the battery 13.

[0036] Furthermore, buckles 17 are fixedly connected to both sides of the headrest 1. The headrest 1 is worn on the user's head by connecting the straps via the buckles 17.

[0037] The working principle of the present invention is as follows: the headrest 1 is tied to the user's head with a strap, the user can turn on the headlamp by pressing the switch button 12, and then according to needs, the lamp head 2 can be rotated to change the angle of illumination, and by pulling the lampshade 25, the distance between the plane lens 26 and the LED lamp bead 24 can be changed to switch between high beam and low beam. It has strong adaptability and is easy to use.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
