Problems solved by technology
This kind of self-generating device, due to the axial movement design of the magnetic element, the movement of the magnetic element stops immediately when the user stops shaking the flashlight, and it cannot generate power when the flashlight is in non-axial movement, making the power generation intermittent and improving the power generation efficiency. Not high; moreover, the magnetic element needs elastic elements at both ends in the torch to allow the magnetic element to bounce back and forth in the barrel to increase the chance of the generator, and the magnetic element will lose part of its mechanical energy when it contacts the elastic element and bounces, and the design of the elastic element also Take up more space

The invention discloses an electronic device and a self-power generation device thereof. The self-power generation device comprises a hollow sleeve body and a magnetic element, wherein a shaft lever which is positioned at the shaft center is arranged in the hollow sleeve body, a coil is at least wound on the sleeve body, the magnetic element is movably sleeved on the shaft lever, gap is retained between the magnetic element and the coil on the hollow sleeve body, the axial length is less than the axial length of a hollow part in the hollow sleeve body, and the magnetic element generates outward lines of magnetic force and at least part of the lines are vertical to the coil; at least part of sub-vector at the direction of the coil at the direction of the hollow sleeve is vertical to the shaft lever, and at least part of the sub-vector is parallel to the shaft lever; and the gravity center of the magnetic element is staggered with the shaft lever. The self-power generation device can carry out power generation when in axial motion and non-axial motion of a vibrator, thereby improving the power generation efficiency.
Description
technical field [0001] The invention relates to the field of electronics, in particular to electronic equipment and a self-generating device thereof. Background technique [0002] Portable electronic devices, such as mobile phones and MP3 players, are favored and adopted by more and more people due to their light and small size, portability and ease of use. These devices are mainly powered by rechargeable batteries and need to be recharged frequently. The most important charging method for portable electronic devices is to use a charger to connect to an external power source to charge. Due to the need for an external power source, this method cannot be used outdoors where there is no power source. [0003] The prior art also provides a self-powered device that mainly utilizes wind energy, solar energy, and mechanical energy to generate electricity. However, when the self-powered device uses wind energy to generate electricity, the volume of the mechanism required is relati...
