Problems solved by technology

Therefore, there are disadvantages such as very large starting current, large size of the starting device, and high cost.
[0015] Second, when the use conditions of the free piston linear generator are different, the average pressure of the combustion gas in the cylinder will continue to change, so the natural frequency of the system will also change greatly with the change of use conditions, so it is difficult to Disadvantages such as stable use and complicated control
[0016] Third, when only the explosive force generated by the combustion gas in the cylinder is used to generate vibration, it is difficult to generate a high natural frequency, which has the disadvantage of making it difficult to reduce size and weight

Embodiment Construction

[0043] The small and lightweight linear generator system with two-stroke free-piston engine provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] figure 1 It is a longitudinal structural sectional view of an embodiment of a small-scale and light-weight linear generator system with a two-stroke free-piston engine provided by the present invention. Figure 2 to Figure 5 forfigure 1 The schematic diagram of each working state of the linear generator system is shown.

[0045] In various forms of linear generators, the structure of the mover has a great influence on the weight of the mover and the efficiency of the generator. The invention is only applicable in the case of linear generators using magnets. Furthermore, the present invention is only described for a small and lightweight linear generator system using a two-stroke engine.

[0046] like figure 1 As shown, the small-scale l...

Abstract

Provided is a small sized light linear generator system having a two-stroke free piston engine, comprising a cylinder having an induction chamber and a combustion chamber, a motor rack arranged at one end of the cylinder, an outer stator fixed inside the motor rack, an inner stator fixed inside the motor rack and having a gap with the outer stator, a rotor carrying out straight reciprocating motion along the gap formed by the outer stator and the inner stator, a magnet installed upon the rotor, a plurality of helical compressing springs arranged inside the motor rack, used for supporting the reciprocating motion of the rotor, and leading to the resonance motion of the rotor, a piston arranged inside the cylinder, connected with rotor for carrying out reciprocating motion, and compressing the fuel and air inside the combustion chamber, a snifter valve arranged upon the cylinder and used for providing fuel and air for the interior of the induction chamber, an induction flow path communicating the induction chamber and the combustion chamber, and an exhaust port arranged upon the cylinder. With the above technical scheme, the free piston linear generator is likely to operate under resonance state, thereby improving the generating efficiency and output power.

Description

technical field [0001] The present invention relates to a small-sized and lightweight linear generator system with a two-stroke free-piston engine, in particular to a two-stroke free-piston engine in which the magnet constituting the movable part is elastically supported by a helical compression spring so that resonance is easily generated small and lightweight linear generator system. Background technique [0002] Recently, with the development of portable electronic and electrical 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,...
