Vehicle-mounted wireless charging base vibration power generation device with high power generation efficiency

Abstract

The invention specifically relates to a vibration power generation device for a vehicle-mounted wireless charging stand with high reliability, good structural stability and high power generation efficiency. The vibration generating device includes a plurality of vibrating layers parallel to each other. The vibrating layer includes a planar honeycomb grid formed by a plurality of honeycomb units. The six sides in the honeycomb unit are made of vibration generators or elastic deformation bodies. Each corner is made up of wires; the vibration generating body includes two helical generating coils coiled with each other to form a DNA double helix structure; along the axial direction of the generating coil, multiple sets of generating units are arranged between the two generating coils; in the generating unit The initial gap between the two permanent magnets can be set very small. When the gap changes, the induced current is very large, which effectively improves the power generation efficiency.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted wireless charging, in particular to a vibration power generation device for a vehicle-mounted wireless charging stand with high power generation efficiency. Background technique [0002] In order to facilitate the charging of mobile phones, there is a new type of wireless charging stand. The principle is to use the principle of vibration coupling to transfer the electric energy on the wireless charging stand to the battery of the mobile phone, but the wireless charging stand itself also needs to be connected to the power supply, which also makes the wireless charging stand Application is limited. In existing cars, most mobile phone charging devices use the cigarette lighter as a power source, or directly lead the power cord from the battery in the engine compartment, and connect the cigarette lighter or power cord to the wireless charging stand to charge the mobile phone. However, the wir...

[0005] And the power generation efficiency of the current vibration power generation device is also low, mainly because the principle of the current vibration power generation device is to generate current by cutting the magnetic induction line through the conductor, but limited by the space, the moving range of the conductor is generally small, so the power generation efficiency is very low
