Abstract

The invention discloses a small-size light-weight linear generator system possessing a double-stroke free piston motor. The small-size light-weight linear generator system includes the double-stroke free piston motor and a linear generator. The double-stroke free piston motor includes a single cylinder which is used to inhale the fuel and the air and a piston which is arranged in the single cylinder, makes the linear reciprocating motion, and at the same time presses the fuel and the air. The linear motor includes a mover which makes the reciprocating motion and a magnet which is arranged on the mover and generates the magnetic force. The inside of the single motor is provided with an air release valve which opens and closes synchronously with the action frequency of the linear generator. The motor system can realize the action synchronous opening and closing of the valve and the motor without arranging an individual synchronous device.

Description

technical field [0001] The invention relates to a linear generator, in particular to a small and lightweight linear generator system with a two-stroke free-piston engine. Background technique [0002] In recent years, with the development of portable electrical and electronic products such as mobile phones, notebook computers, and electric tools, the requirements for high performance and light weight of portable power supplies have also increased rapidly. In addition, electric vehicles and electric bicycles, which are expected to be widely used in the future, will inevitably require larger-capacity portable power supplies, so the research and development work related to portable power supplies has become a current hot spot. [0003] In terms of portable power supply, the technology that is currently applied and studied more is the power supply system using lithium batteries and other batteries. However, the portable power supply in the form of a storage battery has many dis...
