Technical field
The invention belongs to power and drive technology field are and in particular to a kind of oscillating engine, its technology can be not only used for Conventional engine field, but also as a kind of new micro power source dynamical system.
Background technology
With the development of modern advanced, the portable electric appts of every field are popularized very much, provide and continue Permanent electric energy has just become critical problem.The power supply great majority that at present electronic equipment uses be with lithium battery be leading just Take formula chemical energy storage battery, this kind of battery life is short, and charge capacity is less, and the charging interval is long, and energy density is relatively low.If energy Enough develop a kind of energy density high, long operational time, supplements energy convenient portable energy source system, it will have wide city Field prospect.
Liquid carbon hydrogen fuel has a lot of advantages compared with common batteries, and it has very high energy density, such as cycloalkane The energy density of class is exactly 50 times of general commercial battery；And compared with the chemical energy storage battery of equal energy, liquid State hydrocarbon fuel more easily transports and stores, and the advantage also having energy supplement simple and fast.Therefore, at present to liquid Hydrocarbon fuel is that the research of the electromotor of the energy is greatly necessary.
If but electromotor is miniaturized, because hydrocarbon fuel energy density is high, electromotor overall power density can significantly carry Rise, fuel source extensively, builds the micro power source dynamical system great potential based on electromotor in addition.In recent years, with Developing rapidly of micro-machining techniques, also brings wide development space for micropower system.Currently, world many countries are all Accelerate the paces developing tiny engine, various forms of tiny engine model machines come out one after another, such as miniature gas turbine, micro- Type pendulum engine, Micro-rotary engine based on Wankel rotary engine etc..But above-mentioned micro power source dynamical system Output and efficiency are still relatively low, all not yet form the product of maturation.
Content of the invention
The present invention is in order to solve problem of the prior art, there is provided a kind of small volume, lightweight, power to weight ratio is high, output work The miniature oscillating engine of four strokes of the big circular piston of rate.
The invention discloses a kind of miniature oscillating engine of four strokes of circular piston, including a pair positioned opposite sending out Motivation cylinder cap, center pendulum and central shaft；Wherein, the middle inside described engine cylinder cover is annular through-hole, logical in annular Hole both sides cylinder cap is provided with two symmetrical annular compartments, and four ends angle is equipped with screw hole；The centre of described center pendulum is band There is the circular connector of through hole, two ends are arranged with the circular piston being connected with circular connector；Described central shaft is worn simultaneously Cross the annular through-hole on two engine cylinder lids positioned opposite and the center being arranged between engine cylinder cover positioned opposite The through hole of the circular connector of pendulum is so as to engine cylinder cover positioned opposite and center pendulum are combined into one and electric with by output The electromotor of work(is connected.
Improve further, two symmetrical annular compartments are divided into four symmetrical combustion chambers by described circular piston.
Improve further, be equipped with each described combustion chamber near the end of annular compartment and respectively relative to cloth The air inlet put and air vent.
Improve further, described center pendulum is arranged in the annular combustion chamber of engine cylinder cover.
Improve further, described circular piston is in close contact with the wall of annular compartment, and increases on circular piston Sealing ring.
The operation principle of the present invention is：Through the combustion gas of premix, burning is entered by the engine cylinder cover with air inlet Chamber；Control system gathers the phase place of central shaft, controls plug ignition in the swing arm compressed gas end of a period moment, lights intracavity combustion Gas, promotes swing arm acting, and meanwhile a corresponding side cavity opens air vent, discharges waste gas；Four combustor are carried out successively Air-breathing, compression, expansion working, exhaust process, central shaft is connected with electromotor, exports electric work by electromotor.
The beneficial effects of the present invention is：
1）The design adopts four symmetrical annular firing chambeies, and in same cylinder body, work chamber is many, and output is bigger.
2）For the shape of center pendulum, using circular piston and circular chamber, the paste on wall of circular piston and annular compartment Close preferably, and sealing ring increased on circular piston, reduce leakage further so that torque factor is more excellent, more powerful it is ensured that Compression ratio, also substantially increases stability and efficiency simultaneously.

Specific embodiment
As shown in Figure 1-2, the engine cylinder cover 1 of the miniature oscillating engine of four strokes of a kind of circular piston, this starts The middle of machine cylinder cap 1 inner side is annular through-hole 11, is provided with two symmetrical annular compartments 12 on the cylinder cap of annular through-hole both sides, Four ends angle is provided with for being fixedly connected two symmetrical annular compartment all-in-one-piece screw holes 13；It is all provided with each annular compartment There are end and air inlet 14 positioned opposite respectively and the air vent 15 of close annular compartment.
As shown in Figure 3-4, the center pendulum 2 of the miniature oscillating engine of four strokes of a kind of circular piston, described center pendulum Centre be circular connector 21 with through hole, two ends are the symmetrical round property piston being structure as a whole with connector 22.
As seen in figs. 5-6, first will be positioned opposite for two engine cylinder covers, then lay center pendulum 2 between engine cylinder cover, Then central shaft 3 also cross the annular through-hole 11 on two engine cylinder covers 1 positioned opposite and is arranged on positioned opposite Engine cylinder cover between the circular connector 21 of center pendulum 2 through hole, then by screw pass through two engine cylinder lids on Screw hole 13 fastened so that central shaft, center pendulum, engine cylinder cover are combined into the four of circular piston of the present invention The miniature oscillating engine of stroke；Wherein, center pendulum 2 is arranged in the annular combustion chamber of engine cylinder cover, the circle of center pendulum Two symmetrical annular compartments 12 are divided into four symmetrical combustion chambers, four symmetrical combustion chamber size phases by shape piston 22 Deng working method is identical, and stroke order is different；Circular piston is in close contact with the wall of annular compartment, and on circular piston Increase sealing ring, reduce leakage further so that torque factor is more excellent, more powerful.After having combined, lead to through the combustion gas of premix Cross the engine cylinder cover with air inlet 14 and enter combustion chamber, control system gathers the phase place of central shaft, compresses combustion in center pendulum The gas end of a period moment controls plug ignition, lights intracavity combustion gas, promotes swing arm acting, meanwhile a corresponding side cavity opens Air vent 15, discharges waste gas；Four combustor carry out air-breathing successively, compression, expansion working, exhaust process, central shaft and generating Machine is connected, and exports electric work by electromotor.
