Problems solved by technology

[0004] Since the two cylinders of the existing free-piston internal combustion linear generator set are located at both ends of the permanent magnet linear generator, the stroke of the mover is not long enough due to space constraints, so the efficiency of the system cannot be greatly improved
In addition, the existing free-piston internal combustion linear generator sets cannot widely use a variety of fuels, including hydrogen

Embodiment 1

[0017] Example 1 as figure 1 shown. Embodiment 1 comprises two permanent magnet linear generators containing mover 6, stator 7, contains the internal combustion engine of two single cylinders 3, piston 4, ignition and fuel injection system 1, intake and exhaust valve 2, comprises straight rod, The spring lever 12 that the support that the straight rod middle end is provided with, the push rod that the straight rod two ends are provided with constitutes. The ignition and fuel injection system 1 is installed in the middle of the top of the cylinder 3, the intake and exhaust valves 2 are installed on both sides of the ignition and fuel injection system 1 at the top of the cylinder, the cylinder 3 is connected with the stator 7, and the piston push rod connector 5 is connected with the The main shaft of the mover 6 is docked, the mover 6 is fixed in the linear motor stator 7 through the upper positioning guide plate 9 and the lower positioning guide plate 11, the engine push rod ...

Embodiment 2

[0019] Example 2 as figure 2 shown. The difference between embodiment 2 and embodiment 1 is that the permanent magnet linear generators are arranged in two pairs, that is, there are four permanent magnet linear generators, and every two constitute a pair. Every pair of permanent magnet linear generators is the same as Embodiment 1, forming two groups, and the power is greater. The present invention can also adopt the combination form of 3 pairs or more than 3 pairs.

[0020] The thermal efficiency of the invention is 20% higher than that of the traditional internal combustion engine, and when combined with the permanent magnet linear generator, the power of the generator is greatly improved, and the efficiency of the generator is greater than 97%. The biggest highlight is that it can use a variety of fuels, including hydrogen.

Abstract

The invention discloses a pairwise abreast-arrangement free piston permanent-magnet linear generator, belongs to the technical field of electric vehicle engines and mainly solves the problem that system efficiency cannot be improved greatly by an existing free piston permanent-magnet linear generator. The pairwise abreast-arrangement free piston permanent-magnet linear generator is characterized by comprising permanent-magnet linear generators and internal combustion engines, wherein the permanent-magnet linear generators are arranged pairwise and symmetrically and arranged abreast; the internal combustion engines are arranged at one ends of the permanent-magnet linear generators, and upper positioning guide plates are arranged at ports. The other ends of the permanent-magnet linear generators are provided with bouncing levers, each bouncing lever comprises a straight rod, a support seat and push rods, wherein the support seat is arranged in the middle end of the straight rod, and the push rods are arranged at two ends of the straight rod. The support seats are fixed on a generator fixing bottom plate, the push rods at two ends are matched with two rotors respectively, and ends of the rotors, adjacent to the push rods, are provided with push rod magnetism isolation bars. The pairwise abreast-arrangement free piston permanent-magnet linear generator has the advantages that system efficiency is greatly improved and various fuels can be used, and is mainly used for free piston type internal-combustion linear generator units of power sources of electric vehicles.

Description

technical field [0001] The invention belongs to the technical field of generators for electric vehicles, and in particular relates to a dual-double side-by-side free-piston permanent-magnet linear generator for electric-driven vehicle power sources. Background technique [0002] Electric vehicles have been developed and researched all over the world in recent years, and China is no exception. But the effect obtained is not ideal, and still can not be widely promoted, and its main bottleneck is that the battery of the power source cannot be solved. Using hybrid power, but the energy saving can only be about 25%, and the cost is high, so it is difficult to popularize. [0003] At present, in the auxiliary power unit of the series hybrid electric vehicle, the combination of the free piston generator and the linear generator replaces the ordinary engine and the rotary generator, and the crank connecting rod mechanism is omitted, which reduces the weight of the system and improv...
