Embodiment
[0019] Such as figure 1 , figure 2 As shown, an automatic battery charging device includes a machine box 1, which includes a battery box 3, a spring buffer mechanism 6, a guide rail transmission mechanism and a rack and pinion mechanism, and a generator 2 is arranged in the battery box 3 , battery 4, rectification voltage regulation and charging circuit 5, generator 2 has two groups in the present embodiment, is symmetrically arranged in the battery case 3, rectification voltage regulation and charging circuit 5 is placed below the battery 4, and the guide rail transmission mechanism It includes L-shaped guide rails 9 and concave grooves. There are two concave grooves, which are respectively arranged on both sides of the machine box 1. The grooves are fitted together so that the L-shaped guide rail 9 slides relatively in the concave groove to ensure that the battery box 3 moves linearly along the direction of the guide rail. High-quality polytetrafluoroethylene is used as r...

The invention discloses an automatic battery charging device and method. The automatic battery charging device comprises a machine box; a battery box, a spring buffering mechanism, a guide rail transmission mechanism and a gear and rack mechanism are arranged in the machine box; a power generator, a battery and a rectification and voltage regulation and charging circuit are arranged in the battery box; the guide rail transmission mechanism comprises an L-shaped guide rail and a concaved groove; the gear and rack mechanism comprises a gear and a rack, wherein the gear is connected with the power generator and the rack is connected with the machine box. When people move, the damping mass in an excitation device moves in an oscillation mode, the linear vibration movement is converted into the rotating movement through a gear and rack transmission pair, the power generator is driven to rotate and generate power finally, and accordingly the electromechanical conversion is implemented.
Description
technical field [0001] The invention relates to the field of renewable energy, in particular to an automatic battery charging device and a method thereof. Background technique [0002] With the rapid development of science and technology, a series of electronic products have entered people's lives. People often need some electronic devices in their lives, such as mobile phones, computers, cameras, etc. The energy supply of these devices mainly comes from batteries. While battery technology has come a long way, the electrical capacity of batteries still limits the usefulness of these electronic devices. At present, there are also self-charging devices such as solar charging, piezoelectric ceramics to collect electric energy, etc., but solar charging is limited by conditions such as location and weather, and piezoelectric ceramics have relatively low power generation efficiency. Therefore, proposing a new charging method is of great significance to our life. Contents of th...
