AI Technical Summary

Technical Problem

The existing hand-crank flashlights are prone to friction with the lamp shell during the handle flip, which makes it difficult to operate. Users need to control the distance between the handle and the lamp shell, which increases the difficulty of operating the hand-crank power generation.

Method used

The bevel design is adopted to form a height gap between the rocker arm and the lamp shell. The rocker arm is positioned using the limiting plate and the cushion to reduce friction, and optimize the rocker rotation angle by pulling the gap and raising the block to simplify operation.

Benefits of technology

The rocker arm and the lamp shell are frictionless, and the user can rotate the handle at will without adjusting the force control spacing, reducing the difficulty of hand-crank operation and making the operation simpler and lighter.

Abstract

According to the technical scheme, the hand-operated flashlight is characterized in that the hand-operated flashlight comprises a lamp shell, the lamp shell is provided with a rocker arm used for power generation, a rotary disc is installed on the lamp shell, a first shaft is rotationally connected between one end of the rocker arm and the rotary disc, a handle knob is installed at the other end of the rocker arm, and the lamp shell is provided with a long-strip-shaped groove where the rocker arm and the handle knob are placed in a rotating mode. The upper end of the inclined face is higher than the side face of the lamp shell where the inclined face is located so that a height gap can be formed between the rocker arm and the lamp shell, the overturning angle of the handle can be limited through the inclined face design, the distance between the overturned handle and the lamp shell of a mobile phone can be guaranteed, and a user can rotate the handle at will; and the distance between the handle and the lamp shell does not need to be controlled by adjusting the force, so that the hand-cranking operation difficulty of the flashlight is reduced, and the operation is simpler.
