[0006] Preferably, on the cross section of the shaft perpendicular to the rotary valve, the openings of the first air passage and the second air passage are at a central angle spanning 45 to 65 degrees.

[0007] Preferably, at least one of the rotating shaft or the shaft body includes a notch, and the linkage mechanism includes a positioning block disposed between the notch and an actuator.

Implementation Method

[0008] Please refer to Figures 1 and 2, which illustrate a kinetic energy conversion device that is driven by high-pressure gas and then converted into rotational kinetic energy by a crank mechanism. The kinetic energy conversion device includes a valve chamber 10, a rotary valve 20, a gas chamber 40, and a power output mechanism.

[0009] The valve chamber 10 forms an annular chamber, which is connected to an inlet 11 for supplying the high-pressure gas and an outlet 12 for allowing the gas in the chamber 40 to be discharged. A shaft 25 of the rotary valve 20 passes through a bearing 15 and is disposed in the annular chamber. The outer contour of the rotary valve 20 conforms to the inner contour of the annular chamber. The rotary valve 20 has a first air passage 21 aligned with the inlet 11 and a second air passage 22 aligned with the outlet 12, with an included angle between the first air passage 21 and the second air passage 22.

[0010] In order to better understand the spirit of the present invention, the angle between the first air passage 21 and the second air passage 22 shown in the figure is a right angle. The first air passage 21 and the second air passage 22 will be connected to the air inlet 11 or the air outlet 12 depending on the rotation angle of the rotary valve 20.

[0011] The gas chamber 40 is connected to the valve chamber 10, and a piston 45 is provided inside the gas chamber 40. In addition, in this embodiment, the valve chamber 10 and the gas chamber 40 are separated by a platform 30, which also has through holes that are aligned with the extension of the annular gas chamber, so that the interior of the gas chamber 40 is connected to the valve chamber 10.

[0012] The power output mechanism includes a turntable 62, an extension rod 61, a rotating shaft 63, and a linkage mechanism 65. The rotating shaft 63 is positioned in the housing of the air chamber 40 and connected to the turntable 62, such that the rotation center of the rotating shaft 63 is coaxial with the axis of the turntable 62. The two ends of the extension rod 61 are respectively connected to one side of the piston 45 and the radial end defined by the turntable 62. The turntable 62 and the extension rod 61 form the aforementioned crank mechanism, and the rotational displacement is output by the rotating shaft 63. The linkage mechanism 65 is configured to cause the rotating shaft 63 to rotate synchronously with the shaft 25 of the rotary valve 20 and output kinetic energy.

[0013] The linkage mechanism 65 transmits the rotational displacement of the rotating shaft 63 back to the shaft 25 of the rotary valve 20, thus maintaining the rotation of the rotary valve 20 and controlling the intermittent entry of high-pressure gas into the gas chamber 40. The high-pressure gas pushes the piston 45, and the vertical displacement of the piston 45 is converted into the rotational displacement of the rotating shaft 63. In addition, at least one of the shaft 25 of the rotary valve 20 and the rotating shaft 63 can be connected to an additional actuator (not shown), and the kinetic energy output by the linkage mechanism 65 causes the actuator to rotate synchronously.

[0014] In addition, in this embodiment, as an identification feature, the turntable 62 has a triangular outline, but is not limited thereto.

[0015] In one embodiment, the linkage mechanism 65 includes a first pulley 66, a second pulley 67, and a belt 68. The first pulley 66 is positioned on the shaft 25 of the rotary valve 20, and the second pulley 67 is positioned on the rotating shaft 63, such that the rotation center of the second pulley 67 is coaxial with the axis of the rotating shaft 63. The belt 68 connects the first pulley 66 and the second pulley 67.

[0016] In the aforementioned embodiment, the first pulley 66 and the second pulley 67 may have a plurality of teeth and are paired with a toothed belt 68 to ensure synchronous rotation between them. The linkage mechanism 65 is configured to cause the rotating shaft 63 and the shaft 25 of the rotary valve 20 to rotate at equal angles. However, the linkage mechanism 65 may also be a gear, and the combination of gears may also produce deceleration motion. It is not limited to this.

[0017] In one embodiment, on the cross-section of the shaft 25 perpendicular to the rotary valve 20, with the shaft 25 as the center, the openings of the first air passage 21 and the second air passage 22 span a central angle of 45 to 65 degrees. The size of the opening determines whether the first air passage 21 and the second air passage 22 are simultaneously closed or simultaneously open at the same time. The size of the opening can be determined by the overall rotational efficiency.

[0018] In one embodiment, the shaft 25 and the rotating shaft 63 each include a notch 251 and a notch 631. The linkage mechanism 65 includes a positioning block 71 and a positioning block 72 inserted into the notch 251 and a positioning block 731, which are then connected in series to the input shaft of the actuator. Furthermore, the first pulley 66 and the second pulley 67 may also include corresponding notches that cooperate with the notches 251 and a positioning block 71. Taking the positioning block 71 as an example, the positioning block 71 is inserted into the notch 251 of the first pulley 66 and the shaft 25, allowing the first pulley 66 and the shaft 25 to rotate synchronously.

[0019] However, at least one of the rotating shaft 63 or the shaft body 25 may include a notch 251, 631 to output the kinetic energy of the linkage mechanism 65 using a positioning block.

[0020] Please refer to Figures 3 to 13, which illustrate the continuous operation diagram of the kinetic energy conversion device. Based on the aforementioned structure, the source of force on the displacement of the piston 45 inside the air chamber 40 varies slightly in different time sequences. In this continuous operation diagram, the angle between the first air passage 21 and the second air passage 22 is a right angle, and the central angle between the opening of the first air passage 21 and the opening of the second air passage 22 is approximately 60 degrees, which are taken as the conditions for continuous operation.

[0021] Figures 4 to 6, 8 to 10, 12, and 13 are schematic diagrams of the continuous operation. Figure 4 shows the first air passage 21 fully open as 0 degrees. The subsequent figures show the positions of the other components as the first air passage 21 rotates 30 degrees clockwise around the axis of the shaft 25. Figures 3, 7, and 11 are side views of the kinetic energy conversion device at 0 degrees, 90 degrees, and 180 degrees, respectively.

[0022] As shown in Figure 4, at this time, the distance between the piston 45 and the first air passage 21 is the shortest (at the highest position), the opening of the first air passage 21 is completely open, and the opening of the second air passage 22 is completely closed, allowing high-pressure gas to enter the air chamber 40 from the air inlet 11, pushing the piston 45. The piston 45 pushes the extension rod 61 to make the turntable 62 rotate. Then, the force is sequentially transmitted to the rotating shaft 63, the second pulley 67, the belt 68, the first pulley 66, and then to the rotary valve 20 (as shown in Figure 2), causing the rotary valve 20 to rotate.

[0023] As shown in Figure 5, as the rotary valve 20 rotates clockwise, the opening of the first air passage 21 is gradually closed. The piston 45 continues to move downward, and the rotary valve 20 will continue to rotate until the opening of the first air passage 21 is completely closed.

[0024] As shown in Figure 6, as the rotary valve 20 rotates clockwise, the opening of the second air passage 22 gradually opens, allowing the high-pressure gas inside to be discharged towards the air outlet 12. The piston 45 maintains its downward displacement inertia, which also causes the rotary valve 20 to continue rotating clockwise.

[0025] As shown in Figures 7 and 8, as the rotary valve 20 rotates clockwise, the opening of the second air passage 22 is fully opened, releasing the internal pressure. The piston 45 can still continue to move downwards due to its own inertia.

[0026] As shown in Figure 9, as the rotary valve 20 rotates clockwise, the opening of the second air passage 22 is gradually closed. During this stage, if the piston 45 has insufficient inertia to produce downward displacement, it can also continue to move downward through the pulling of the belt 68.

[0027] As shown in Figure 10, as the rotary valve 20 rotates clockwise, the opening of the first air passage 21 is gradually opened, allowing high-pressure gas to enter the air chamber 40 again from the air inlet 11 and push the piston 45.

[0028] As shown in Figures 11 and 12, as the rotary valve 20 rotates clockwise, the opening of the first air passage 21 is fully opened, and the opening of the second air passage 22 is fully closed. A large amount of high-pressure gas enters the air chamber 40 from the air inlet 11, pushing the piston 45 to its lowest position, at which point the piston 45 is at its longest distance from the first air passage 21. When this force is transmitted from the extension rod 61 to the turntable 62, combined with the rotational torque of the turntable 62, the extension rod 61 is rotated upwards due to inertia. This force also causes the rotating shaft 63 to rotate, and then is transmitted to the rotary valve 20.

[0029] As shown in Figure 13, as the rotary valve 20 rotates clockwise, the opening of the first air passage 21 is gradually closed, and the piston 45 is displaced upward by the inertia of the extension rod 61.

[0030] The remaining continuous actions follow the same pattern until the piston 45 rises to its highest position. The force that causes the piston 45 to move upward can be the pushing force of the extension rod 61 due to inertia, or it can be driven by the pulling force of the belt 68.

[0031] The aforementioned operating method is merely an illustrative example. In other embodiments, the kinetic energy conversion device of the present invention can be operated primarily by high-pressure gas, and secondarily by the inertia of the piston 45, the extension rod 61, or the belt 68 at different times. In this way, the kinetic energy conversion device of the present invention can operate continuously, outputting rotational kinetic energy through the shaft 25, the rotating shaft 63, and / or the positioning blocks 71, 72.
