Description

Technical Field

[0001] The invention relates to a flashlight, in particular to a flashlight with Beidou positioning and short message position sending functions. Background Art

[0002] With the improvement of living standards, people pay more and more attention to the quality of life. Holiday travel is increasing. The travel destinations have changed from scenic spots to development tours. Some people even backpack in pursuit of returning to nature and go deep into primeval forests, deserts and other uninhabited areas. Once an emergency occurs in this situation, how to send their location information to inform family and friends in real time and request rescue becomes a problem.

[0003] The positioning system occupies an increasingly important position in our lives. When we go out, we will use mobile navigation and WeChat to share our location in real time so that rescue can be implemented quickly in an emergency. Of course, the prerequisite is that there must be a network signal. When there is a network, you can use the mobile phone to send GPS location information and find your location easily. In the absence of network signals or poor communication conditions, such as when natural disasters such as earthquakes and tsunamis cause communication interruptions, how can you send your own positioning information, real-time location tracking and emergency rescue; or when you are abroad and cannot join the country's network in time, how can you send your own positioning information.

[0004] As outdoor sports become more and more popular, flashlights have become a must-have item for outdoor activities. Rechargeable flashlights are a new type of lighting tool that uses light-emitting diodes as light sources. They are energy-saving, durable, and bright. Rechargeable flashlights are handheld electronic lighting tools that can be recharged repeatedly. They are green and environmentally friendly. They usually use LED bulbs with a long lifespan and are suitable for nighttime outings and power outages. At present, flashlights are mainly used for lighting, so their functions are relatively simple. Summary of the invention
