The utility model discloses a dual-mode charging anti-wolf flashlight, which relates to the technical field of flashlights and comprises a barrel shell, and a lighting component and an electric shock component are arranged at the front end of the barrel shell. A rechargeable lithium battery electrically connected with the lighting assembly and the electric shock assembly is arranged in the barrel shell, a plurality of mounting notches are formed in the outer wall of the barrel shell, and photovoltaic panels are fixedly connected into the mounting notches. And the hand-cranking power generation assembly is arranged at the tail end part of the barrel shell. According to the utility model, on one hand, the photovoltaic panel is connected with the internal rechargeable lithium battery through a circuit to convert solar energy into electric energy to be stored, and on the other hand, the hand-cranking power generation assembly drives the generator through hand cranking to generate electric energy to be supplied to the rechargeable lithium battery; the rechargeable lithium battery can be charged through hand-cranking operation in the absence of sunlight. The power output of the hand-cranking device is matched with the requirement of the battery, and it is ensured that the flashlight can still work even in the environment without illumination for a long time.

The invention provides an energy-saving flashlight with multiple power generation modes, which belongs to the technical field of flashlights and comprises a flashlight main body, a speed increasing mechanism, a clamping mechanism, a power generation mechanism and a switching mechanism. Wherein the flashlight main body is internally provided with a lighting assembly and has a basic lighting function; the speed increasing mechanism is arranged on the flashlight body, the output end of the speed increasing mechanism is electrically connected with an energy storage battery arranged in the flashlight body, and the speed increasing mechanism can convert low-speed rotation generated by external force driving into high-speed rotation so as to improve the power generation efficiency; the clamping mechanism is arranged on the inner side wall of the flashlight body, the speed increasing mechanism is clamped and fixed to the clamping mechanism, and the clamping mechanism can achieve limiting and rapid disassembly and assembly of the speed increasing mechanism; and the input end of the power generation mechanism is fixedly connected with the input shaft of the speed increasing mechanism, and the power generation mechanism comprises four rotating arm assemblies. The device integrates two modes of gyroscope stirring power generation and ball throwing power generation, power generation can be maintained through stirring or throwing, and continuous high-frequency power generation is not needed.
