Vehicle vibration power generation device with USB interface

Abstract

The invention relates to a vehicle vibration power generation device with a USB interface. The device adopts a heavy hammer and a double-acting type ratchet wheel as a vibration pickup mechanism, a gear set is a vibration mechanical energy transmission mechanism, a direct current permanent magnet generator is an electromechanical energy conversion mechanism, and an electric energy processing circuit with a USB interface processes irregular direct current electric energy, and supplies power to a vehicle-mounted electronic device. The vehicle vibration power generation device uses the double-acting type ratchet wheel mechanism for vibration pickup, converts rectilinear motion in vehicle running to rotational motion, and drives the low damping permanent magnet direct current generator to work through the efficient gear mechanism, and compared with a common linear type vibration power generation device, the transmission and conversion efficiency of vibration mechanical energy can be significantly improved. The vehicle vibration power generation device with the USB interface generates power by renewable energy, the vibration pickup efficiency, and the energy transmission and conversion efficiency are high, the working life is long, the USB interface is adopted to be suitable for the use of most vehicle-mounted electronic devices, and the universality is strong.

Description

technical field [0001] The present invention relates to the technology of converting the mechanical energy of vehicle vibration into electric energy, in particular to the device of heavy hammer and ratchet type vibration pickup mechanism, DC permanent magnet generator and its realization method, specifically adopting heavy hammer, double-action ratchet, gear set , a DC permanent magnet generator, a power processing circuit with a USB interface, a magnetic attraction, and a housing, and realizes a device that converts vibration mechanical energy during vehicle driving into electrical energy. Background technique [0002] Vehicles are becoming more and more popular in life and production, and the applications of related portable electronic devices are also increasing, such as: car navigators, driving recorders, handheld electronic devices for drivers and passengers, etc. These electronic devices mainly rely on on-board power supply or built-in Batteries provide electricity, wh...

AI Technical Summary

Problems solved by technology

[0003] 1. The use of on-board power supply requires the output of electric energy by the car generator, which will increase the fuel consumption of the vehicle. In today's high oil price, it is obviously not economical and increases environmental pollution

[0004] 2. Portable electronic devices powered by batteries have a short battery life and need to carry charging equipment, and the use of batteries also causes pollution

[0005] 3. Many vehicle-mounted portable electronic devices are powered by USB power supply. The original vehicle power supply needs to be connected to an external power converter to convert the 12V cigarette lighter power supply to USB power supply. The secondary power supply efficiency is low and the cost is high.

[0006] 4. Messy power cords affect the cleanliness and beauty of the car
