Description

Technical Field

[0001] The utility model relates to the technical field of headlights, in particular to a wireless charging headlight. Background Art

[0002] A headlamp is an essential piece of equipment for outdoor activities, such as night hiking and camping. Although some people say that a flashlight is almost as effective as a headlamp, the newer headlamps use energy-saving technologies, such as LED cold light technology, and innovative lamp cup materials on high-end headlamps, which are incomparable to flashlights of affordable prices. So, a headlamp can replace a flashlight, but a flashlight cannot replace a headlamp.

[0003] The charging structure of a traditional headlamp is generally configured with a charging port for connecting to a charging head to complete charging of the power supply. For example, an LED headlamp disclosed in Chinese patent announcement number "CN216844214U" includes a shell and a support plate. The lower end of the shell is rotatably connected to the lower end of the support plate. The support plate is used to connect to the human head. A light guide plate is fixed to the front end of the shell. A light board, a circuit board and a battery are fixed in the shell from front to back in sequence. A button for controlling the on and off of the LED lamp beads on the light board is fixed on the circuit board, and a button for triggering the button is installed on the side wall of the shell.

[0004] With the continuous development of the times, people have put forward higher requirements for the charging methods of headlights. Although the traditional wired charging method is reliable, it seems single and somewhat cumbersome. In comparison, the wireless charging method is more convenient and practical, and can better meet people's needs. Based on this, in order to further improve the applicability of existing headlights, we propose a wireless charging headlight. Utility Model Content
