Description

Technical Field

[0001] The invention relates to the technical field of engines, in particular to a dual-rotor variable lever arm engine. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. Internal combustion engines usually convert chemical energy into mechanical energy. The term engine can be applied to power generation devices or the entire machine including the power device.

[0003] The piston engines widely used in automobiles currently have the following shortcomings:

[0004] In the process of doing work, this kind of engine converts the reciprocating linear motion of the piston into circular motion through the crankshaft connecting rod mechanism. Due to its low mechanical energy conversion efficiency and small torque, most of the energy of the engine is converted into vibration and becomes useless work. In addition, the effective diameter of the engine's intake and exhaust valves is limited by size, and a lot of energy is consumed during intake and exhaust. Therefore, the efficiency of the piston engine is not high. Summary of the invention

[0005] The object of the present invention is to provide a dual-rotor variable lever arm engine to solve the problem of low working efficiency in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: the engine is mainly composed of a cylinder body, an inner rotor, an air guide hole, a sealing guide shoe, an outer rotor, an exhaust port, a shaft, a spark plug, an air inlet and left and right end covers.

[0007] Preferably, the cylinder (1) is composed of two annular cylinders A and B arranged in series, cylinder A is for intake and compression, and cylinder B is for work and exhaust. The inner wall circles of cylinders A and B are respectively secanted by a circle which is eccentric to the inner wall circle of the cylinder and has a radius equal to that of the inner rotor to form a concave arc surface.

[0008] Preferably, the air inlet (9) is arranged on the cylinder body A, the exhaust port (6) is arranged on the cylinder body B, and the spark plug (8) is arranged on the concave arc surface of the inner wall circle of the cylinder body B.

[0009] Preferably, the inner rotor (2) is two circular discs with a sector-shaped notch, and is connected to the shaft (7) as a whole by a key, and is respectively clamped in three circular ring discs with the same inner and outer diameters of the outer rotor (5), and is eccentrically arranged with the center of the concave arc surface on the inner wall circle of the cylinder body A and the cylinder body B as the center of the circle, and respectively seals the concave arc surface on the inner wall circle of the cylinder body A and the cylinder body B, and is positioned by relying on the cylinder body A and the cylinder body B, the shaft (7), and the left and right end covers 10.

[0010] Preferably, the outer rotor (5) is a hollow cylinder formed by connecting three annular disks with the same inner and outer diameters and two symmetrically arranged sector blocks, and is axially penetrated from the side by a circle with a radius equal to the radius of the sealing guide shoe (4) and a center on the edge of a coincident straight line of the two symmetrically arranged sector-shaped connecting blocks, and its cross section is an asymmetric cross section with half of a circular arc on one side of the sector-shaped connecting block. After the sealing guide shoe (4) is inserted into the circle, the cross section is combined with the cross section of the sealing guide shoe (4) to form an approximate sector shape, and the approximate sector shape is basically consistent with the sector-shaped notch of the inner rotor (2). The air guide hole (3) is arranged on the annular disk in the middle of the outer rotor (5).

[0011] Preferably, the outer rotor (5) is arranged concentrically with the two annular cylinder bodies, cylinder body A and cylinder body B, and is positioned by cylinder body A and cylinder body B and left and right end covers 10.

[0012] Preferably, the sealing guide shoe (4) is arranged on the outer rotor (5) and can rotate freely around the center of the circle. In cylinder body A, the inner rotor (2) drives the outer rotor (5) to rotate synchronously in cylinder body A through the sealing guide shoe (4); in cylinder body B, the outer rotor (5) drives the inner rotor (2) to rotate synchronously in cylinder body B through the sealing guide shoe (4).

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The twin-rotor variable lever arm engine is achieved through the cooperation of the cylinder body, inner rotor, air guide hole, sealing guide shoe, outer rotor, exhaust port, shaft, spark plug, air inlet and left and right end covers. When the inner rotor pushes the outer rotor to rotate synchronously in the cylinder body, the closed space formed between the two and the inner wall of the cylinder body continuously expands and shrinks, thereby completing the cycle of intake, compression, work and exhaust.

[0015] 1. Due to the unique inner and outer rotor structure, the engine realizes a rotating working mode. There is no piston and crankshaft connecting rod mechanism, so the efficiency can be greatly improved, while the volume is reduced and the manufacturing cost is reduced.

[0016] 2. Using a dual-cylinder structure, one cylinder takes in air and compresses, and the other cylinder does work and exhausts, so that the compressor no longer needs intake and exhaust valves, and the intake and exhaust are unobstructed, which improves the intake and exhaust efficiency and reduces the failure rate and manufacturing cost.

[0017] 3. Due to the unique inner and outer rotor structure, the thrust generated by the explosion of the mixed oil and gas when the engine is working is always perpendicular to the radius of the inner rotor, and the torque is maximum. In addition, based on the inner rotor lever arm, the lever arm can also continuously change (increase or decrease) within a certain range, further increasing the engine torque.

[0018] 4. Since there are no inlet and exhaust valves, the inner and outer rotors rotate around their respective centers during operation, and the speed of the inner and outer rotors can be very high after being counterweighted.

[0019] Compared with the prior art, the beneficial effects of the present invention are: novel conception, ingenious design, and unique inner and outer rotor structure, which makes the engine lever arm variable, has large torque, high efficiency, small size, simple and reliable structure.

[0034] As a preferred solution of this embodiment: the cylinder body 1 is composed of two annular cylinder bodies A and B arranged in series, one for intake and compression, and the other for power and exhaust. The inner wall circles of the cylinder body A and the cylinder body B are respectively sected by a circle eccentric to the inner wall circle of the cylinder body and having a radius equal to the inner rotor 2 to form a concave arc surface.

[0035] As a preferred solution of this embodiment: the air inlet 9 is arranged on the cylinder A, the exhaust port 6 is arranged on the cylinder B, and the spark plug 8 is arranged on the concave arc surface of the inner wall of the cylinder B, which can ignite the compressed oil-gas mixture in the cylinder B.

[0036] As a preferred solution of this embodiment: the inner rotor 2 is two discs with a sector-shaped notch, and is connected to the shaft 7 by a key and has the center of the concave arc surface on the inner wall of the cylinder body A and the cylinder body B as the center of the circle. It is respectively clamped in three circular ring discs with the same inner and outer diameters of the outer rotor 5, and is eccentrically arranged with the cylinder body A and the cylinder body B to seal the concave arc surface on the inner wall of the cylinder body A and the cylinder body B, and can rotate freely in the two annular cylinder bodies of the cylinder body A and the cylinder body B.

[0037] As a preferred solution of this embodiment, the outer rotor 5 is placed concentrically with the two annular cylinder bodies A and B, and is positioned by the cylinder bodies A and B, the shaft (7), and the left and right end covers 10. It can rotate freely in the annular cylinder bodies A and B.

[0038] As a preferred solution of this embodiment: the outer rotor 5 is a hollow cylinder connected by three circular ring disks with the same inner and outer diameters and two symmetrically arranged sector blocks. It is axially penetrated from the side by a circle with a radius equal to the radius of the sealing guide shoe 4 and a center on the edge of a coincident straight line of two symmetrically arranged sector connecting blocks. Its cross section is an asymmetric cross section with half of a circular arc on one side of the sector connecting block. After the sealing guide shoe 4 penetrates into it, the cross section is combined with the cross section of the sealing guide shoe 4 to form an approximate sector shape, which is just basically consistent with the sector notch of the inner rotor 2. The air guide hole 3 is set on the circular ring disk in the middle of the outer rotor 5. For easy installation, the cylinder body 1 and the outer rotor 5 should be processed separately.

[0039] As a preferred solution of this embodiment: the sealing guide shoe 4 is placed on the outer rotor 5 and can rotate freely around its center. In cylinder body A, the inner rotor 2 pushes the outer rotor 5 to rotate synchronously through the sealing guide shoe 4. In cylinder body B, the outer rotor 5 pushes the inner rotor 2 to rotate synchronously through the sealing guide shoe 4.

[0040] Working principle: Figure 2 As shown, when the engine is running, driven by the shaft 7 in the cylinder body A, the inner rotor 2 pushes the outer rotor 5 to rotate in the clockwise direction through the sealing guide shoe 4, and the outer rotor 5 divides the cavity in the cylinder body A into two parts, V1 and V2. The oil-gas mixture is sucked into V1 from the air inlet 9, and at the same time, the oil-gas mixture sucked in last time is compressed in V2; because the outer rotor 5 in the cylinder body A and the cylinder body B are connected as a whole, at this time, the outer rotor 5 in the cylinder body B pushes the inner rotor 2 to rotate in the clockwise direction through the sealing guide shoe 4, and divides the cavity in the cylinder body B into two parts, V3 and V4. The compressed oil-gas mixture introduced from the cylinder body A last time is ignited and exploded to do work in V3, and the force arm at this time gradually approaches the maximum, and at the same time, the exhaust gas after the previous work in V4 is discharged through the exhaust port 6, and the air guide hole 3 is blocked at the same time.

[0041] The inner and outer rotors in cylinder A and cylinder B continue to rotate until Figure 3 When in the position shown, V1 in cylinder A continues to inhale the oil-gas mixture, and the oil-gas mixture inhaled last time in V2 begins to be pressed into the cavity being formed between the outer rotor 5 and the concave arc surface of the inner wall of cylinder A; the combustion gas in V3 in cylinder B continues to do work, the lever arm is gradually getting smaller, and the exhaust gas after the previous work in V4 is about to be discharged.

[0042] The inner and outer rotors in cylinder A and cylinder B continue to rotate until Figure 4At the position shown, the air intake process of V1 in cylinder A is completed, and the oil-gas mixture inhaled last time in V2 has been compressed into the cavity formed between the outer rotor 5 and the concave arc surface of the inner wall circle of cylinder A, and V2 disappears; at this time, the air guide hole 3 begins to be unblocked, and the oil-gas mixture inhaled last time compressed in cylinder A begins to enter the cavity being formed between the outer rotor 5 and the concave arc surface of the inner wall circle of cylinder B through the air guide hole 3; the work of the combustion gas in V3 in cylinder B is about to end, and the lever arm at this time is equal to the lever arm of the inner rotor, the exhaust gas after the previous work is completely discharged, and V4 disappears.

[0043] The inner and outer rotors in cylinder A and cylinder B continue to rotate until Figure 5 At the position shown, the compressed oil-gas mixture in cylinder A that was sucked in last time will be swept into the cavity formed between the outer rotor 5 and the concave arc surface of the inner wall of cylinder B. At this time, the air inlet 9 of cylinder A is blocked, and a new round of compression process begins; the work of the gas in cylinder B is finished, V3 disappears, and the lever arm at this time is equal to the lever arm of the inner rotor, and the high-pressure exhaust gas after work is discharged from the exhaust port 6.

[0044] The inner and outer rotors in cylinder A and cylinder B continue to rotate until Figure 6 At the position shown, the compression process of V2 in cylinder A continues, and the air guide hole 3 is blocked again. The spark plug 8 in cylinder B begins to ignite the compressed mixed oil and gas introduced into the cavity formed between the outer rotor 5 and the concave arc surface of the inner wall of cylinder B. A new round of work process begins, and the force arm at this time begins to gradually increase, and the purpose of power output is achieved through continuous cycles.
