AI Technical Summary

Technical Problem

When it is necessary to drive a circular object with a larger diameter to rotate, if a force is applied at the center of the circle, a large force is required to make the circular object rotate, and the driving shaft is very easy to damage when driven by a power source such as a motor. At the same time, if the rotational force is applied to the center position and the edge position of the circular object at the same time, a reaction force hedging will occur, resulting in the circular object being unable to rotate.

Method used

A power transmission mechanism is designed, including an inertial wheel, a drive wheel, a one-way rotary connection and a drive assembly. By setting the drive wheels in the circumference of the inertial wheel and using a one-way rotating connection to prevent the hedging of the reaction force, the power transmission mechanism can ensure that the circular object obtains a higher rotation speed when the input is small.

Benefits of technology

It realizes the high rotation speed of the driving circular object with a larger diameter under the input of a smaller force, avoids damage to the drive shaft, and solves the problem of reaction force hedging, ensuring that the circular object can rotate smoothly.

Description

Power transmission mechanism and equipment using the same Technical Field

[0001] The present invention relates to the field of driving force transmission devices, in particular to a power transmission mechanism and equipment using the power transmission mechanism. Background Art

[0002] Existing driving force transmission devices basically transmit rotational force by applying an external force to the edge of a circular object or to the center of the circular object. Transmitting rotational force through the edge of the circle is a labor-saving lever. However, the larger the radius, the smaller the percentage of the moving arc length to the circumference of the circle, which means that the rotation speed of the circle is reduced. Transmitting rotational force through the center of the circle is a labor-intensive lever, but it can solve the problem of the small percentage of the moving arc length, thereby ensuring that the circular object can achieve a higher rotation speed. Therefore, when outputting the same torque, since torque T = F*r, where F is the force and r represents the lever arm length, only a smaller force needs to be input at the edge of the circle to drive the object to rotate, while a larger force needs to be input at the center of the circle to drive the object to rotate. Technical issues

Using a motor or other power source to drive the object can easily damage the drive shaft.

Beneficial effects

[0016] By providing a drive wheel around the circumference of the inertia wheel, the drive wheel transmits a rotational force to the inertia wheel, creating a force-saving lever. Only a relatively small force is required to drive the inertia wheel in rotation. Simultaneously, the first drive shaft on the inertia wheel ensures that the circular object achieves a high rotational speed. Furthermore, if a rotational force is simultaneously applied to both the center and the edge of the circular object, the reaction forces between the two forces will counteract each other, potentially locking the inertia wheel and preventing it from rotating. To overcome this problem, the present invention provides a second unidirectional rotating connector between the drive wheel and the second drive shaft. When the two forces counteract each other, the drive wheel rotates slightly in the opposite direction relative to the second drive shaft, eliminating the impact of the counteracting forces between the two rotational forces and preventing continued rotation in the original direction after becoming stuck.

[0017] Furthermore, by providing a fluid pipe component around the circumference of the inertia wheel, the direction of the force exerted by the fluid discharged from the outlet of the fluid pipe component on the first drive wheel is the same as the direction of rotation of the inertia wheel. Transmitting the rotational force to the inertia wheel via the fluid acts as a force-saving lever, requiring only a relatively small input force to drive the inertia wheel. Simultaneously, the first drive shaft on the inertia wheel ensures that the inertia wheel achieves a high rotational speed. Furthermore, if a rotational force is simultaneously applied to the center and edge of a circular object, the reaction forces between the two forces will counteract each other, potentially causing the inertia wheel to become stuck and unable to rotate. To overcome this problem, the present invention provides a first unidirectional rotating connector between the inertia wheel and the first drive shaft. When the two forces counteract each other, the inertia wheel rotates slightly in the opposite direction relative to the first drive shaft, eliminating the impact of the reaction force between the two forces and preventing continued rotation in the original direction after becoming stuck. Furthermore, in this embodiment, because the liquid or gas is in a soft state, the reaction force exerted on the inertia wheel is very small, extending its service life and making it more suitable for locations with a large inertia wheel radius.

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments. Modes for Carrying Out the Invention

[0035] Referring to Figures 1 to 3 , the power transmission mechanism in this embodiment includes an inertia wheel 11, a drive wheel 12, a first one-way rotating connector 13, a second one-way rotating connector 14, and a drive assembly 15. Preferably, both the first one-way rotating connector 13 and the second one-way rotating connector 14 utilize ratchet mechanisms. Alternatively, the first one-way rotating connector 13 and the second one-way rotating connector 14 may utilize one-way bearings.

[0036] The inertia wheel 11 is provided with a first drive wheel portion 111 and a first drive shaft 112. The first drive wheel portion 111 and the first drive shaft 112 are both arranged coaxially with the inertia wheel 11. The drive wheel 12 is meshed with the first drive wheel portion 111. The diameter of the drive wheel 12 is smaller than the diameter of the first drive wheel portion 111. The drive wheel 12 is provided with a second drive shaft 121. The second drive shaft 121 is arranged coaxially with the drive wheel 12. The first drive wheel portion 111 is provided on the outer peripheral wall of the inertia wheel 11.

[0037] The first drive wheel portion 111 is connected to the first drive shaft 112 via a first one-way rotating connection 13. The first one-way rotating connection 13 includes a first inner rotating portion 131 and a first outer rotating portion 132 arranged in a radial direction. The first drive wheel portion 111 is fixedly connected to the first inner rotating portion 131, and the first drive shaft 112 is fixedly connected to the first outer rotating portion 132. The first one-way rotating connection 13 also includes a first ratchet 133, which is located between the first inner rotating portion 131 and the first outer rotating portion 132. The inner peripheral wall of the first outer rotating portion 132 is provided with a plurality of first teeth 134 arranged along the circumferential direction. The first end of the first ratchet 133 is hinged to the first inner rotating portion 131, and the second end of the first ratchet 133 abuts against the first teeth 134, so that the first outer rotating portion 132 can only rotate unidirectionally in the first direction relative to the first inner rotating portion 131.

[0038] The drive wheel 12 is connected to the second drive shaft 121 via a second one-way rotating connector 14. The second one-way rotating connector 14 includes a second inner rotating portion 141 and a second outer rotating portion 142 arranged radially. The second outer rotating portion 142 is unidirectionally rotatable relative to the second inner rotating portion 141, and the second direction is the same as the rotation direction of the flywheel 11. The first direction is opposite to the second direction. The drive wheel 12 and the second outer rotating portion 142 are integrally formed, and the second drive shaft 121 is fixedly connected to the second inner rotating portion 141. The second one-way rotating connection member 14 also includes a second ratchet 143, which is located between the second inner rotating part 141 and the second outer rotating part 142. A plurality of second teeth 144 arranged along the circumferential direction are provided on the inner peripheral wall of the second outer rotating part 142. The first end of the second ratchet 143 is hinged to the second inner rotating part 141, and the second end of the second ratchet 143 abuts against the second teeth 144, so that the first outer rotating part 132 can only rotate unidirectionally along the first direction relative to the first inner rotating part 131.

[0039] The first drive shaft 112 and the second drive shaft 121 are both drivingly connected to the drive assembly 15. The drive assembly 15 includes a power source 151, a first transmission member 152, a second transmission member 153, and an intermediate gear 154. Preferably, the power source 151 is an electric motor. Alternatively, the power source 151 may be an internal combustion engine or a force application rod, which can apply force manually (e.g., by pedaling or hand cranking).

[0040] The drive shaft of the power source 151 is provided with a second drive wheel portion 155 and a third drive wheel portion 156, which are arranged coaxially therewith. The first outer rotating portion 132 is provided with a fourth drive wheel portion 135, which is arranged coaxially therewith. The first transmission member 152 is wound around the second and fourth drive wheel portions 155, 135. Both the first and second transmission members 152, 153 are transmission belts or chains. The third drive wheel portion 156 meshes with an intermediate gear 154. The second drive shaft 121 is also provided with a fifth drive wheel portion 122, which is arranged coaxially therewith. The second transmission member 153 is wound around the intermediate gear 154 and the fifth drive wheel portion 122.

[0041] As can be seen from the above, by providing a drive wheel around the circumference of the inertia wheel and transmitting the rotational force to the inertia wheel through the drive wheel, a force-saving lever is employed. Only a relatively small force is required to drive the inertia wheel to rotate. At the same time, the first drive shaft on the inertia wheel can ensure that the circular object achieves a high rotational speed. Furthermore, if a rotational force is simultaneously applied to both the center and the edge of the circular object, the reaction forces between the two forces will counteract each other, potentially blocking the inertia wheel and rendering it unable to rotate. To overcome this problem, the present invention provides a second unidirectional rotating connector between the drive wheel and the second drive shaft. When the two forces counteract each other, the inertia wheel rotates slightly in the opposite direction relative to the second drive shaft, thereby eliminating the impact of the reaction forces between the two rotational forces and preventing it from continuing to rotate in the original direction after becoming stuck.

[0042] The device incorporating the first embodiment of the power transmission mechanism of the present invention may include a bicycle, a four-wheeled vehicle, an electric vehicle, a ship, a power generation device, an air compressor, or an electric aircraft, among others. The electric vehicle may include an electric bicycle, an electric tricycle, an electric four-wheeled vehicle, or an electric vehicle with four or more wheels. The device incorporating the first embodiment of the power transmission mechanism of the present invention may further include a solar cell assembly for powering the drive assembly.

[0043] Figures 4 and 5 are schematic structural diagrams of a bicycle using the first embodiment of the power transmission mechanism of the present invention. In Figure 4, the power source 151 is a pedal, and the inertia wheel 11 is the rear wheel of the bicycle.

[0044] Figure 6 shows a schematic diagram of the structure of a four-wheeled electric vehicle utilizing the first embodiment of the power transmission mechanism of the present invention. The power transmission mechanism can be arranged horizontally within the vehicle body, with the axis of the flywheel extending vertically. The purpose of the four-wheeled electric vehicle's onboard flywheel 11 is to output rotational power, which is converted into electrical energy by a generator to charge the battery. By simultaneously driving the flywheel 11 from both the center and the edge of the circle, the force applied by the edge of the circle can be reduced due to the large radius of the circle.

[0045] Figure 7 is a schematic diagram of the structure of a ship using the first embodiment of the power transmission mechanism of the present invention. In Figure 7, the output shaft of the inertia wheel 11 is connected to the input shaft of the generator 10 on the ship.

[0046] Figure 8 is a schematic diagram of the structure of an air compressor using the first embodiment of the power transmission mechanism of the present invention. The output shaft of the inertia wheel 11 drives the piston to move and compress the gas.

[0047] As a description of the second embodiment of the power transmission mechanism of the present invention, only the differences from the first embodiment of the power transmission mechanism described above will be described below.

[0048] Referring to Figure 9, in this embodiment, the drive assembly 25 includes a power source 251 and a connecting shaft 252. The connecting shaft 252 is provided with a first bevel gear portion 253 and a second bevel gear portion 254 at each end. The first drive shaft 212 is provided with a third bevel gear portion 213, which is coaxially arranged with the first drive shaft 212 and meshes with the first bevel gear portion 253. The second drive shaft 221 is provided with a fourth bevel gear portion 222, which is coaxially arranged with the second drive shaft 221 and meshes with the second bevel gear portion 254. The shaft portion of the power source 251 is coaxially arranged and fixedly connected to the second drive shaft 221. In this embodiment, the power source 251 includes a hand crank 2511, which is manually cranked to provide driving force. The first drive wheel portion 211 is disposed on the outer peripheral wall of the flywheel 21.

[0049] By arranging a driving wheel 22 at the circular edge of the inertia wheel 21, the driving wheel 22 transmits the rotational force to the inertia wheel 21, which is a force-saving lever. Only a small force needs to be input to drive the inertia wheel 21 to rotate. At the same time, the first driving shaft 212 on the inertia wheel 21 can ensure that the inertia wheel 21 obtains a higher rotation speed.

[0050] As a description of the third embodiment of the power transmission mechanism of the present invention, only the differences from the first embodiment of the power transmission mechanism described above will be described below.

[0051] Referring to Figure 10 , in this embodiment, there are at least two inertia wheels 31 and two drive wheels 32. One inertia wheel 31 and one drive wheel 32 constitute a power transmission assembly 30. Of two adjacent power transmission assemblies 30, in the direction of driving force transmission, the first drive shaft 312 of the upstream power transmission assembly 30 is drivingly connected to the second drive shaft 321 of the downstream power transmission assembly 30. The upstream power transmission assembly 30 is the one closest to the power source 351.

[0052] As a description of a fourth embodiment of the power transmission mechanism of the present invention, only the differences from the first embodiment of the power transmission mechanism described above will be described below.

[0053] Referring to Figure 11 , in this embodiment, there are at least two inertia wheels 41 and drive wheels 42. One inertia wheel 41 and one drive wheel 42 constitute a power transmission assembly 40. The first drive shaft 412 and the second drive shaft 421 in each power transmission assembly 40 are both drivingly connected to the drive assembly 45. The inertia wheels 41 in each power transmission assembly 40 are coaxially arranged, and the drive wheels 42 in each power transmission assembly 40 are coaxially arranged. The output shaft of each inertia wheel 41 is connected to the input shaft of a generator 43.

[0054] FIG11 is a schematic structural diagram of a four-wheeled vehicle using a fourth embodiment of a power transmission mechanism according to the present invention.

[0055] Figure 12 shows a front view of an electric aircraft utilizing a fourth embodiment of the power transmission mechanism of the present invention. Figure 13 shows a top view of an electric aircraft utilizing a fourth embodiment of the power transmission mechanism of the present invention. The electric aircraft has an appropriately sized inertia wheel 41 horizontally positioned atop a cockpit 44, based on its required power and its specific requirements.

[0056] As a description of the fifth embodiment of the power transmission mechanism of the present invention, only the differences from the first embodiment of the power transmission mechanism described above will be described below.

[0057] 14 and 15 , in this embodiment, the driving assembly 55 includes a first power source 551 and a second power source 552 . The first power source 551 is drivingly connected to the first driving shaft 512 , and the second power source 552 is drivingly connected to the second driving shaft 521 .

[0058] As a description of the second embodiment of the power transmission mechanism of the present invention, only the differences from the first embodiment of the power transmission mechanism described above will be described below.

[0059] 16 , the power transmission mechanism includes an inertia wheel 61 , a first one-way rotating connector (not shown), a fluid supply device 66 , a fluid pipe component 64 , and a drive assembly 65 . The fluid pipe component 64 is in communication with the fluid supply device 66 .

[0060] The inertia wheel 61 is provided with a first drive wheel portion 611 and a first drive shaft 612. Both the first drive wheel portion 611 and the first drive shaft 612 are arranged coaxially with the inertia wheel 61. The inertia wheel 61 and the first drive shaft 612 are connected by a first unidirectional rotating connection. The first unidirectional rotating connection includes a first inner rotating portion and a first outer rotating portion arranged radially. The first outer rotating portion can only rotate unidirectionally in a first direction relative to the first inner rotating portion. In this embodiment, the first direction is counterclockwise. The first drive wheel portion 611 is fixedly connected to the first outer rotating portion, and the first drive shaft 612 is fixedly connected to the first inner rotating portion. The first drive shaft 612 is drivingly connected to the drive assembly 65. The outlet 641 of the fluid tube component 64 faces the first drive wheel portion 611. The direction of the force exerted by the fluid discharged from the outlet 641 of the fluid tube component 64 on the first drive wheel portion 611 is the same as the direction of rotation of the inertia wheel 61. The fluid can be either a gas or a liquid. The first one-way rotating connector in this embodiment has the same structure as that in the first embodiment, and will not be described in detail herein. The fluid supply device 66 may be a water pump or an air compressor.

[0061] The first driving wheel portion 611 includes blades 610 arranged on the outer peripheral wall of the inertia wheel 61. The plurality of blades 610 extend outward from the outer peripheral wall of the inertia wheel 61 along the radial direction of the inertia wheel 61. The arrangement of the blades 610 facilitates better absorption of the force applied to the inertia wheel 61 by the fluid. Industrial Applicability

[0062] By providing a fluid pipe component or a drive wheel around the circumference of the inertia wheel, the direction of the force applied by the drive wheel or the fluid discharged from the outlet of the fluid pipe component to the first drive wheel portion is the same as the direction of rotation of the inertia wheel. Transmitting the rotational force to the inertia wheel via the drive wheel or the fluid acts as a force-saving lever, requiring only a relatively small input force to drive the inertia wheel to rotate. Simultaneously, the first drive shaft on the inertia wheel ensures that the inertia wheel achieves a high rotational speed. Furthermore, if a rotational force is simultaneously applied to the center and edge of the same circular object, the reaction forces between the two forces will counteract each other, causing the inertia wheel to seize and become unable to rotate. To overcome this problem, the present invention provides a first unidirectional rotating connector between the inertia wheel and the first drive shaft, and a second unidirectional rotating connector between the drive wheel and the second drive shaft. When the two forces counteract each other, the inertia wheel rotates slightly in the opposite direction relative to the first drive shaft, or the drive wheel rotates slightly in the opposite direction relative to the second drive shaft, thereby eliminating the impact of the counteracting forces between the two rotational forces and preventing continued rotation in the original direction after being stuck. In addition, in this embodiment, because the liquid or gas is in a soft state, the reverse force applied to the inertia wheel is very small, which can extend the service life. It is more suitable for places with a large radius of the inertia wheel and has good industrial applicability.

[0063] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
