Description

Technical Field

[0001] This utility model relates to the field of helmet light technology, specifically a multifunctional helmet light. Background Technology

[0002] A helmet light is a portable lighting device that can be worn on the head and mounted on a safety helmet or helmet using a fixing device. It combines the light source with the user's head, so that the light moves synchronously with the line of sight, thereby providing direct and stable lighting while the hands are engaged in other tasks. It is widely used in fields such as fire rescue, mining operations, outdoor exploration, cycling and industrial maintenance, and has become an important auxiliary tool for professional operations and outdoor activities.

[0003] Existing helmet lights have certain drawbacks. There is a significant contradiction between high brightness and battery life and heat dissipation. In pursuit of high lumen output, many products set the "ultra-bright" setting to only last for a few minutes before automatically and drastically reducing the brightness due to overheating. This results in insufficient usable brightness over long periods, failing to meet the demand for continuous high-brightness illumination. Furthermore, the fixed modes are limited and lack adaptability. In professional scenarios such as firefighting, traditional helmet lights often rely on elastic bands to be tied to the outer edge of the helmet, making installation cumbersome and interfering with firefighters' goggles and other equipment, affecting ease of use and safety. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional helmet light to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multifunctional helmet light includes a helmet light body, which includes a lighting module, a drive control module, and a telescopic bracket. The telescopic bracket includes a helmet bracket, a buckle, and a main shell. The helmet bracket has a telescopic buckle on its exterior, a bracket on the buckle, and a bracket accessory on the bracket. The main shell for mounting the lighting module is located between the bracket accessory and the bracket. A screw and a compression spring are disposed inside the buckle, and one end of the screw passes through the helmet bracket. The lighting module includes a PCBA located at the light outlet of the main housing and LED beads mounted on the PCBA. An upper housing is provided outside the main housing. A reflector and reflector accessories are provided outside the LED beads. The reflector and reflector accessories are both located inside the upper housing. The drive control module includes a battery, a button bracket, and a button. The main housing has a battery compartment for installing the battery. The battery compartment has a battery spring and a battery accessory at both ends. The battery accessory has a battery contact piece on its exterior. The openings at both ends of the battery compartment are provided with end caps and waterproof rings. The main housing has a button bracket on its exterior, and the button is mounted on the button bracket.

[0006] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: a locking block is provided on the side of the bracket near the main shell, and multiple locking slots are provided on the main shell to cooperate with the locking block. The engagement of the locking block with different locking slots realizes the angle adjustment of the main shell relative to the bracket.

[0007] In one alternative: the buckle is provided with a fixing bracket, the fixing bracket is provided with a fixing block, and the fixing block is snapped into the bracket.

[0008] In one alternative: the helmet bracket has a fixing buckle inside, and the fixing buckle is equipped with a compression spring and a fixing clip.

[0009] In one alternative: the upper shell is provided with a plurality of screws, and the main shell is provided with a waterproof ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The frame of the multi-functional helmet light is made of die-cast aluminum, which has good thermal conductivity and excellent heat dissipation. The battery is replaceable, and the battery compartment is made of all-aluminum structure with a certain degree of explosion-proof performance. It uses a low-power MCU to control a high-precision LED constant current driver chip, which accurately controls the light current to achieve long battery life and optimal brightness. While obtaining sufficient illumination, it keeps the hands free, greatly improving the safety and efficiency of operation. The helmet light's beam is always aligned with the user's field of vision, eliminating the trouble of deliberately aiming a traditional flashlight and avoiding accidents such as tripping and collisions caused by blind spots. The light head has a lifting structure and a quick-release structure, which can be clipped onto the fire helmet for easy replacement, reducing fatigue caused by frequent head rotation.
