Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a headlamp. Background Art

[0002] In the prior art, headlamps are commonly used lighting equipment in the wild, mining areas and other environments. They are worn on the head and illuminate the road ahead through the front lighting, freeing the hands to a certain extent.

[0003] The existing utility model patent with announcement number CN208579184U discloses a lithium battery headlamp, including a lithium battery headlamp device body, a headlamp and a lithium battery. A headlamp is arranged in front of the lithium battery headlamp device body, and the headlamp is fixedly connected to the lithium battery headlamp device body. A lithium battery is arranged behind the headlamp, and the lithium battery is connected through the headlamp. A circuit board is arranged at the bottom of the headlamp, and the circuit board is fixedly connected to the headlamp. A connector is arranged at the middle part of the top of the circuit board, and the connector is fixedly connected to the circuit board. A power-on head is arranged, and the power-on head and the hidden wire inside the first hidden port on the lithium battery can be pulled out and connected to the headlamp to energize the headlamp. After use, the hidden wire and the power-on head can be retracted, which saves the use space well. An adjuster is arranged, and the length of the connecting belt can be adjusted by the adjuster according to the size of the user's head.

[0004] However, the headlamp of this application is large in size, does not fit the shape of the head, is uncomfortable to wear, and only has a spotlighting effect, a small lighting range, and the length of the connecting belt can only be adjusted directly through an adjuster. The shape of a human head is irregular, so this application cannot quickly locate the head to a suitable position. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a headlamp with a simple structure, small size, better adaptability to the shape of the head, large lighting range, good lighting effect and adjustable up and down rotation in view of the above-mentioned deficiencies in the prior art.

[0006] To achieve the above-mentioned purpose, the following technical scheme is adopted: a headlamp, comprising a shell and an arc-shaped base, a headband is passed through the arc-shaped base, a mounting base is provided in the shell, a circuit board is provided on the first surface of the mounting base, a lithium battery is provided on the second surface of the mounting base, LED lamp beads are provided on the circuit board, a lampshade groove is provided in the shell, a light-transmitting hole is provided in the lampshade groove corresponding to the position of the LED lamp beads, a lampshade is embedded in the lampshade groove, a light-collecting bowl is provided on one side of the lampshade, which extends from the light-transmitting hole and covers the outside of the LED lamp beads, the light-collecting bowl comprises a first light-blocking cover covering the outside of the LED lamp beads, a second light-blocking cover is provided in the first light-blocking cover with a height lower than the first light-blocking cover, a light-collecting protrusion is provided in the second light-blocking cover with a height between the first light-blocking cover and the second light-blocking cover, a light-guiding ring with a diameter greater than the inner diameter of the first light-blocking cover is provided on the other side of the lampshade, and the light-guiding ring is spliced ​​by a plurality of hexagonal protrusions to form a honeycomb structure.

[0007] By adopting the above technical solution, the circuit board can embed the LED lamp beads on the circuit board through four protrusions on the upper, lower, left and right sides. The lithium battery can be charged and discharged and has a long battery life. The arc surface of the arc base is facing the forehead, so it is not easy to feel pain when worn on the forehead. Since the human forehead also has a certain curvature, the arc base can also be more suitable for the human forehead. The function of the lampshade groove is to position the lampshade to prevent the lampshade from shifting after installation. The first light blocking cover in the focusing bowl completely covers the LED lamp beads, so there is little light leakage. The LED lamp beads are high-brightness LED lamp beads, and the light they emit is diffuse. Most of the outer edge light is refracted back through the first light blocking cover, thereby focusing the light source for the first time. The light source then passes through the focusing protrusion, which is equivalent to a convex lens, thereby further converging the light source, and finally the scattered light around the focusing protrusion is blocked again by the second light blocking cover, thereby increasing the concentration of the light source again, and the concentration effect of the light source is increased through three concentrations, and finally a honeycomb light guide ring is formed by splicing hexagonal protrusions. The shape of the light guide ring is also circular, and the loss of light brightness of the light source is smaller than that of other shapes. At the same time, this shape can effectively prevent glare, improve the lighting effect, and increase the lighting range, so that the light source has a certain brightness without being dazzling, and can also reduce the size of the headlamp through a single LED lamp bead, making the headlamp lighter and more comfortable to wear.

[0008] A headlamp can be further configured as follows: a rotation groove is provided on the arc-shaped base, a rotating block is provided in the rotation groove and is protruded toward the shell body, the shell body and the rotating block cooperate to realize the shell body rotating up and down along the arc-shaped base, and headband grooves for the headband to pass through are provided on the left and right sides of the rotation groove.

[0009] Using the above technical solution, the shape of the rotating block is an inverted U-shape, the middle block is cylindrical, the shell is rotatably connected to the rotating block, the headband is inserted into the headband groove on one side, then fits with the side of the arc base away from the shell, and then passes out from the headband groove on the other side. The outer side of the headband groove can be provided with an oblique groove to make it easier to remove the headband.

[0010] A headlamp can be further configured as follows: a rotating base is provided on one side of the shell facing the arc-shaped base, a rotating upper cover is provided on the rotating base, and an arched groove for a rotating block to rotate is provided on opposite sides of the rotating base and the rotating upper cover, the rotating base and the rotating upper cover are positioned on the upper and lower sides of the arched groove by multiple groups of grooves and protrusions, at least one group of grooves and protrusions is fixed between the rotating upper cover and the rotating base by bolts, and the arched groove is provided for the rotating block to rotate and realize the rotation of the shell along the arc-shaped base.

[0011] By adopting the above technical scheme, the rotating base and the rotating upper cover are both arched, and the two arched grooves are matched by the grooves and the protrusions to form a circular groove, and the circular groove is provided for the rotating block to rotate. At this time, the shell can rotate along the arc base. When the two rotate, when the shell flips up or down to a certain angle, it will abut against the arc base, thereby limiting its rotation angle. The bolts are inserted from the rotating upper cover and fixed to the rotating base. The position of the bolts can be in the middle. Arc grooves can be provided at the upper and lower ends of the rotating groove for the bolts to pass through, thereby preventing the bolts from colliding with the arc base when rotating, thereby increasing the service life. At the same time, because the other parts of the rotating upper cover abut against the arc base, the up and down flipping angles can be limited, so that the headlight will not hit the glasses, thereby increasing the safety and stability of the headlight.

[0012] A headlamp may be further configured as follows: a first baffle and a second baffle arranged in parallel are provided on the first surface of the mounting base plate, and the lithium battery is located between the first baffle and the second baffle.

[0013] By adopting the above technical solution, the first baffle plate and the second baffle plate can prevent the lithium battery from shifting, making the lithium battery easier to place.

[0014] A headlamp can be further configured as follows: a switch button is provided on the upper side or lower side of the shell, a charging port is provided on the left side or right side of the shell, and the charging port is covered with a waterproof silicone pad that can be rotatably arranged with the shell.

[0015] Using the above technical solution, the shape of the switch button adopts a larger rectangular structure with rounded edges. Since most people turn on and off the headlights with their right hand or left thumbs, setting the switch button at the top or bottom is more in line with daily living habits. The charging port can be used for repeated charging of the headlight, and the waterproof silicone pad can protect the charging port, thereby increasing the waterproof effect of the entire headlight.

[0016] A headlamp can be further configured as follows: at least two adjustment buckles are provided on the headband, and anti-slip grooves are provided at the upper and lower ends of each adjustment buckle.

[0017] By adopting the above technical solution, the headbands on both sides can be adjusted at the same time through the adjustment buckle, so that the headbands can be adjusted to the most comfortable angle, and the headlight will not be misaligned due to unilateral adjustment, resulting in poor lighting effect.
