Description

Technical Field

[0001] The present invention relates to the technical field of power generation devices, and particularly to an energy-saving power generation device for fitness equipment. Background Art

[0002] With the continuous rise of the fitness craze in recent years, more and more people have engaged in fitness activities. As a common fitness equipment, the dynamic bicycle has been widely promoted. It drives the flywheel to rotate by human power and uses the inertia of the flywheel to provide adjustable resistance, so as to meet the personalized exercise needs of different users. In order not to cause energy waste, people gradually convert the kinetic energy generated by the dynamic bicycle into electrical energy and store it through an energy-saving power generation device.

[0003] At present, traditional energy-saving power generation devices usually generate electricity by the way of the driving wheel contacting the flywheel. The flywheel drives the driving wheel to rotate through friction, and the driving wheel drives the generator shaft to rotate and generate electricity. Although this way can achieve the purpose of power generation, after long-term use, due to the large inertia generated by the large-scale movement of the human body, the inertia force drives the dynamic bicycle to shake for a long time. The flywheel follows the shaking of the dynamic bicycle and drives the driving wheel to shake. The displacement generated by the shaking of the two makes the gap between the driving wheel and the flywheel larger, the contact surface smaller, and even the contact surfaces are separated from each other, resulting in a significant reduction in power generation efficiency. Users need to check and adjust frequently, which greatly reduces the practicability of the power generation device. Moreover, after long-term use, dust will accumulate on the surfaces of the flywheel and the driving wheel, and the dust will reduce the friction force of the contact surfaces of the two, affecting the power generation efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an energy-saving power generation device for fitness equipment to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: An energy-saving power generation device for fitness equipment includes a bottom plate support. A power storage base and a bearing are installed on the bottom plate support. Positioning components are symmetrically and rotatably installed on the power storage base. A first electric telescopic rod is installed between the positioning components and the bottom plate support. A cleaning device is installed on the positioning components. A power generation rotating rod is rotatably installed between the positioning components through a bearing. An induction driving wheel is installed on the power generation rotating rod. A power generation component is installed on the power generation rotating rod. The power generation component is connected to the positioning component. The power generation component is connected to the power storage base through a wire component. The first electric telescopic rod and the positioning component are both connected to the power storage base through a wire component.

[0006] A control system is provided inside the power storage base, which is used to control the entire power generation device. The power storage base can store the electrical energy transmitted by the power generation component, and can also store energy for the power storage base through external charging. The power storage base provides electrical energy for the first electric telescopic rod and the second electric telescopic rod. The control system is interconnected with the control system of the dynamic bicycle and shares data.

[0007] First, install the bottom plate support near the power bicycle so that the induction drive wheel is aligned with the flywheel of the power bicycle. After that, the staff makes the first electric telescopic rod extend or contract through the control system. The output shaft of the first electric telescopic rod drives the positioning side plate to rotate, so that the end of the positioning side plate is aligned with the center point of the flywheel of the power bicycle.

[0008] The positioning component includes a positioning side plate, which is rotatably installed on the power storage base platform. There is a groove on one side of the positioning side plate. A second electric telescopic rod is installed in the groove. A pre-tightening force slider is installed on the output shaft of the second electric telescopic rod. The pre-tightening force slider is slidably connected to the positioning side plate. A bearing is installed on the pre-tightening force slider. A power generation rotating rod is installed between the pre-tightening force sliders through the bearing. One side of the pre-tightening force slider is connected to the power generation component, and the other side of the pre-tightening force slider is connected to the cleaning device. The second electric telescopic rod is connected to the power storage base platform through a wire assembly.

[0009] After that, the control system activates the second electric telescopic rod. The second electric telescopic rod drives the pre-tightening force slider to extend forward. The pre-tightening force slider drives the power generation rotating rod to move through the bearing. The power generation rotating rod drives the induction drive wheel to move, so that the induction drive wheel is in close contact with the flywheel. After that, the output shaft of the second electric telescopic rod further extends forward, so that the induction drive wheel continues to move. At this time, the induction drive wheel cannot continue to move under the blockage of the flywheel, so that the power generation rotating rod cannot move either. Subsequently, the positioning slider connected to the power generation rotating rod through the bearing, as well as the positioning slide rod and the anti-disengagement block on the positioning slider, cannot move. Under the thrust of the second electric telescopic rod, the sliding box overcomes the elastic force of the pre-tightening force spring, compresses the pre-tightening force spring and continues to slide in the groove of the positioning side plate until the pre-tightening force spring is completely compressed. The control system stops the second electric telescopic rod. At this time, the induction drive wheel is in close fit with the flywheel. After the pre-tightening force spring is compressed, it gives an anti-thrust to the anti-disengagement block, so that the anti-disengagement block has a tendency to slide away from the sliding box. The anti-disengagement block transmits the thrust through the positioning slide rod, the positioning slider, the bearing and the power generation rotating rod to the induction drive wheel finally, so that the induction drive wheel generates a pre-tightening force on the flywheel, increasing the friction between the induction drive wheel and the flywheel. And when the induction wheel and the flywheel are displaced and move away from each other, under the elastic force of the pre-tightening force spring, the anti-disengagement block will slide in the direction away from the sliding box, thereby driving the induction drive wheel to move in the direction of the flywheel, ensuring that the induction drive wheel is always in close fit with the flywheel.

[0010] The pre-tightening force slider includes a sliding box and a positioning slide rod. The sliding box is connected to the output shaft of the second electric telescopic rod. The sliding box is slidably connected to the positioning side plate. One end of the positioning slide rod penetrates through the sliding box and is installed with a positioning slider. The other end of the positioning slide rod is installed with an anti-disengagement block. A pre-tightening force spring is installed between the anti-disengagement block and the sliding box. One side of the positioning slider is connected to the power generation component, and the other side of the positioning slider is connected to the cleaning device.

[0011] The induction drive wheel includes a drive runner, which is installed on the power generation rotating rod. A drive outer tire is installed on the drive runner. An induction ring is movably installed on the drive runner. The induction ring is fitted with the drive outer tire. A fixed rod is installed inside the drive runner. A limiting piece is installed on the fixed rod. An induction piece is slidably installed between the limiting pieces. A strip-shaped groove is provided on the induction piece. The fixed rod penetrates through the strip-shaped groove. Spring connecting plates are symmetrically installed on the induction piece. A return spring is installed between the spring connecting plate and the inner wall of the drive runner. A piezoelectric element is installed inside the drive runner. An induction contact is installed on the induction piece. The induction contact corresponds to the position of the piezoelectric element. A drive gear is installed on one side of the drive runner. The drive outer tire is made of rubber or other materials with a high coefficient of friction. Due to the characteristics of rubber, the drive outer tire is prone to dust contamination, and the dust on the flywheel is easily attached to the surface of the drive outer tire.

[0012] When the user pedals the power bicycle, with the rotation of the flywheel, the induction drive wheel is driven to rotate. The induction drive wheel drives the power generation component to generate electricity through the power generation rotating rod. An extrusion force will be generated at the contact surface between the induction drive wheel and the flywheel. Under the action of the extrusion force, the part of the drive outer tire in contact with the flywheel is squeezed and undergoes a slight deformation. The deformation of the drive outer tire drives the drive outer ring to squeeze the induction piece. The induction piece overcomes the elastic force of the return spring and drives the induction contact to squeeze the piezoelectric element. After being pressed, the piezoelectric element generates an electric current and transmits it to the control system. The control system analyzes the magnitude of the pressure received by the piezoelectric element through the magnitude of the current, thereby analyzing the magnitude of the extrusion force received by the drive outer tire, and judging the contact situation between the induction drive wheel and the flywheel according to the magnitude of the extrusion force. When the extrusion force is too small, the control system activates the positioning component and repeats the previous operation to apply a pre-tightening force to the induction drive wheel. At the same time, according to the time interval between the electrical signals transmitted by multiple piezoelectric elements, the rotation speed of the induction drive wheel can be analyzed. A short time interval indicates a fast rotation speed of the induction drive wheel, and vice versa, it indicates a slow rotation speed of the induction drive wheel.

[0013] The cleaning device includes a connecting plate, an air extraction component, and an air extraction connecting piece. The connecting plate member is connected to the positioning slider. A bearing is fitted on the connecting plate member. The air extraction component is connected to the cleaning and dust suction component through the air extraction connecting piece. The cleaning and dust suction component is installed on the connecting plate member. A cleaning connecting rod is installed on the cleaning and dust suction component. The air extraction component is rotationally connected to the cleaning connecting rod. A cleaning cylinder is installed on the connecting plate member. The output shaft of the cleaning cylinder is connected to the cleaning and dust suction component.

[0014] When the pressure data transmitted according to the induction drive wheel is good, but the rotational speed of the flywheel of the exercise bike is quite different from the rotational speed of the monitored induction drive wheel, it proves that the friction between the flywheel and the induction drive wheel has decreased. At this time, the control system activates the cleaning cylinder, and the output shaft of the cleaning cylinder pushes the dust collection box forward. The air extraction housing connected to the dust collection box through the air extraction connecting piece, and the air extraction gear connected to the dust collection box through the cleaning connecting rod, slide forward together with the dust collection box, so that the entire air extraction assembly slides along with the cleaning and dust collection assembly. When the air extraction gear meshes with the transmission gear, the control system stops the contraction of the output shaft of the cleaning cylinder. At this time, the opening of the dust collection box is near the transmission outer tire, and the bristles on the cleaning roller in the dust collection box just contact the transmission outer tire.

[0015] The air extraction assembly includes an air extraction housing and an air extraction gear. The air extraction housing is connected to the cleaning and dust collection assembly through an air extraction connecting piece. The air extraction gear is rotatably connected to the cleaning connecting rod. An eccentric and rotatable gear connecting rod is installed on the air extraction gear. One end of the gear connecting rod is rotatably installed with a piston connecting rod, and one end of the piston connecting rod is rotatably installed with a piston head. The piston head is slidably installed in the air extraction assembly. An air outlet pipe is installed at one end of the air extraction housing. A one-way opening and closing air outlet valve is provided at the connection between the air outlet pipe and the air extraction housing. An air inlet pipe is installed on the air extraction housing. A one-way opening and closing air inlet valve is provided at the connection between the air inlet pipe and the air extraction housing. One end of the air inlet pipe is internally connected to the cleaning and dust collection assembly. The air extraction gear is meshed and driven with the cleaning and dust collection assembly. The connecting plate member is slidably connected to the positioning side plate.

[0016] The transmission gear rotates together with the induction drive wheel. The transmission gear drives the air extraction gear to rotate. The air extraction gear drives the gear connecting rod to rotate eccentrically. The gear connecting rod drives the piston head to reciprocate inside through the piston connecting rod. When the piston head moves forward, it will squeeze the gas in the air extraction housing. At this time, the air outlet valve at the connection between the air outlet pipe and the air extraction housing opens under the pressure, allowing the gas to be discharged. When the piston head moves backward, the cavity between the piston head and the air extraction housing becomes larger, generating a negative pressure. At this time, the air inlet valve at the connection between the air inlet pipe and the air extraction housing opens, sucking the gas in the air extraction box into the air extraction housing, so that a negative pressure is generated in the air extraction box. The air extraction box sucks the air in the dust collection box, generating a negative pressure in the dust collection box, and blocking the dust through the filter screen to prevent the dust from entering the air extraction housing through the air extraction box. This process repeats, generating a continuous suction force in the dust collection box, sucking away the dust on the surface of the transmission outer tire, and also sucking the dust swept by the cleaning roller into the dust collection box.

[0017] The cleaning and dust suction assembly includes a dust suction box and a cleaning rotating shaft. The cleaning rotating shaft is rotatably installed in the dust suction box. One end of the cleaning rotating shaft penetrates through the dust suction box and is equipped with a cleaning gear. The cleaning gear is in meshing transmission with an air extraction gear. A cleaning roller is installed on the cleaning rotating shaft. An air extraction box is installed on the dust suction box. The air extraction box is internally connected to the dust suction box. An air inlet pipe is internally connected to the air extraction box. A filter screen is provided at the connection between the air extraction box and the dust suction box. A cleaning connecting rod is installed on the dust suction box. The dust suction box is installed on a connecting plate member. The dust suction box is connected to an air extraction connecting piece. Brush hairs are provided on the cleaning roller. The dust suction box is connected to the output shaft of a cleaning air cylinder.

[0018] While the air extraction gear rotates, it drives the cleaning gear to rotate. The cleaning gear drives the cleaning roller to rotate through the cleaning rotating shaft. The cleaning roller rotates in the opposite direction relative to the induction transmission wheel. The brush hairs on the cleaning roller rotate in the opposite direction to the transmission outer tire, and more quickly sweep the dust on the transmission outer tire. The swept dust is sucked away by the dust suction box. At the same time, under the action of the dust suction box, the dust is more likely to fall off from the transmission outer tire. The cleaned transmission outer tire adsorbs the dust on the flywheel, and then is cleaned again. Eventually, both the flywheel and the transmission outer tire can be cleaned.

[0019] The power generation assembly includes a power generation outer shell and a rotor connecting piece. The power generation outer shell is connected to a positioning slider. A power generation rotating rod is rotatably connected to the power generation outer shell. A stator connecting piece is installed inside the power generation outer shell. A stator coil is installed on the stator connecting piece. A PMG auxiliary exciter is installed inside the power generation outer shell. The PMG auxiliary exciter is rotatably connected to the power generation rotating rod. The rotor connecting piece is installed on the power generation rotating rod. A rotor coil is installed on the rotor connecting piece.

[0020] When the power generation rotating rod rotates, it drives the PMG auxiliary exciter to operate and generate current, and supplies power to the rotor coil, causing the rotor coil to generate magnetic force. The rotor coil is driven to rotate through the rotor connecting piece. The magnetic induction lines of the rotor coil are cut by the surrounding stator coils, causing current to be generated in the stator coils. The current enters the power storage base through the wire assembly and is stored by the power storage base.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention drives the induction transmission wheel to be in close contact with the flywheel of the power bicycle through the positioning assembly, and the pre-tightening force slider causes the induction transmission wheel to generate a pre-tightening force on the flywheel, increasing the friction force between the induction transmission wheel and the flywheel. And when the induction wheel and the flywheel are displaced and move away from each other, under the elastic force of the pre-tightening force spring, the anti-disengagement block will slide in the direction away from the sliding box, thereby driving the induction transmission wheel to move towards the flywheel, ensuring that the induction transmission wheel is always in contact with the flywheel and improving the power generation efficiency.

[0022] The squeezing force received by the induction drive wheel is converted into an electrical signal. The control system analyzes the magnitude of the squeezing force received by the induction drive wheel based on the magnitude of the current, and determines the contact situation between the induction drive wheel and the flywheel according to the magnitude of the squeezing force. When the squeezing force is too small, the pre-tightening force of the induction drive wheel is adjusted through the positioning component to ensure good contact between the induction drive wheel and the flywheel. At the same time, by analyzing the time interval of the electrical signals transmitted by multiple piezoelectric elements, the purpose of detecting the rotation speed of the induction drive wheel is achieved.

[0023] The flywheel drives the induction drive wheel to rotate, thereby driving the operation of the air extraction component. The air extraction component drives the cleaning and dust suction component to operate synchronously. The bristles on the cleaning roller and the transmission outer tire rotate in opposite directions, and the dust on the transmission outer tire is swept off more quickly. The dust suction box generates continuous suction, so that the dust on the surface of the transmission outer tire is sucked away, and the dust swept by the cleaning roller is also sucked into the dust suction box, ensuring the cleanliness of the induction drive wheel and the flywheel, preventing the reduction of the friction force between the two due to dust, and achieving the purpose of ensuring the power generation efficiency through self-cleaning.

[0024] The induction drive wheel is used to drive the power generation component. The power generation rotating rod drives the PMG auxiliary exciter to operate and generate current, so that the rotor coil is energized to become an electromagnet. Then, the rotor rotates to cut the magnetic induction lines by the stator coil, and the stator coil generates current, thereby achieving the purpose of power generation; the electric energy transmitted by the power generation component stored in the power storage base station can also be charged externally to store energy for the power storage base station.

[0025] The first electric telescopic rod is used to drive the positioning side plate to rotate, realizing the automatic adjustment of the angle of the positioning side plate, which is convenient for the subsequent contact between the induction drive wheel and the flywheel.

[0050] After that, the control system activates the second electric telescopic rod 32. The second electric telescopic rod 32 drives the pre-tightening force slider 33 to extend forward. The pre-tightening force slider 33 drives the power generation rotating rod 8 to move through the bearing 9. The power generation rotating rod 8 drives the induction transmission wheel 7 to move, making the induction transmission wheel 7 come into close contact with the flywheel. After that, the output shaft of the second electric telescopic rod 32 further extends forward, causing the induction transmission wheel 7 to continue moving. At this time, the induction transmission wheel 7 cannot continue to move due to the blockage of the flywheel, so that the power generation rotating rod 8 cannot move either. Subsequently, the positioning slider 331 connected to the power generation rotating rod 8 through the bearing 9, as well as the positioning slide rod 333 and the anti-disengagement block 335 on the positioning slider 331, cannot move. Under the thrust of the second electric telescopic rod 32, the sliding box 332 overcomes the elastic force of the pre-tightening force spring 334, compresses the pre-tightening force spring 334 and continues to slide in the groove of the positioning side plate 31 until the pre-tightening force spring 334 is completely compressed. The control system stops the second electric telescopic rod 32. At this time, the induction transmission wheel 7 is in close fit with the flywheel. After the pre-tightening force spring 334 is compressed, it gives a reverse thrust to the anti-disengagement block 335, making the anti-disengagement block 335 tend to slide away from the sliding box 332. The anti-disengagement block 335 transmits the thrust through the positioning slide rod 333, the positioning slider 331, the bearing 9 and the power generation rotating rod 8 to the induction transmission wheel 7 ultimately, causing the induction transmission wheel 7 to generate a pre-tightening force on the flywheel, increasing the friction between the induction transmission wheel 7 and the flywheel. And when the induction wheel and the flywheel are displaced and move away from each other, under the elastic force of the pre-tightening force spring 334, the anti-disengagement block 335 will slide in the direction away from the sliding box 332, thereby driving the induction transmission wheel 7 to move in the direction of the flywheel, ensuring that the induction transmission wheel 7 is always in contact with the flywheel.

[0051] When the user pedals the exercise bike, with the rotation of the flywheel, it drives the induction transmission wheel 7 to rotate. The induction transmission wheel 7 drives the power generation assembly 6 to generate electricity through the power generation rotating rod 8. An extrusion force will be generated on the contact surface between the induction transmission wheel 7 and the flywheel. Under the action of the extrusion force, the part of the transmission outer tire 71 in contact with the flywheel is squeezed and undergoes a slight deformation. The deformation of the transmission outer tire 71 drives the transmission outer ring to squeeze the induction sheet 75. The induction sheet 75 overcomes the elastic force of the return spring 76 and drives the induction contact 77 to squeeze the piezoelectric element 78. The piezoelectric element 78 generates an electric current after being pressed and transmits it to the control system. The control system analyzes the magnitude of the pressure received by the piezoelectric element 78 through the magnitude of the current, thereby analyzing the magnitude of the extrusion force received by the transmission outer tire 71, and judging the contact situation between the induction transmission wheel 7 and the flywheel according to the magnitude of the extrusion force. When the extrusion force is too small, the control system activates the positioning assembly 3 and repeats the previous operation to apply a pre-tightening force to the induction transmission wheel 7. At the same time, according to the time interval between the electrical signals transmitted by multiple piezoelectric elements 78, the rotation speed of the induction transmission wheel 7 can be analyzed. A short time interval indicates that the induction transmission wheel 7 rotates fast, and vice versa, it indicates that the induction transmission wheel 7 rotates slowly.

[0052] When the pressure data transmitted according to the induction drive wheel 7 is good, but there is a large difference between the rotational speed of the power bike flywheel and the monitored rotational speed of the induction drive wheel 7, it proves that the friction between the flywheel and the induction drive wheel 7 has decreased. At this time, the control system activates the cleaning cylinder 55, and the output shaft of the cleaning cylinder 55 pushes the dust suction box 541 forward to slide. The air extraction housing 525 connected to the dust suction box 541 through the air extraction connecting piece 53, and the air extraction gear 523 connected to the dust suction box 541 through the cleaning connecting rod 57, all slide forward together with the dust suction box 541. As a result, the entire air extraction assembly 52 follows the cleaning and dust suction assembly 54 to slide. When the air extraction gear 523 meshes with the transmission gear 711, the control system stops the output shaft of the cleaning cylinder 55 from contracting. At this time, the opening of the dust suction box 541 is near the transmission outer tire 71, and the bristles on the cleaning roller 543 in the dust suction box 541 just contact the transmission outer tire 71.

[0053] The transmission gear 711 rotates together with the induction drive wheel 7. The transmission gear 711 drives the air extraction gear 523 to rotate. The air extraction gear 523 drives the gear connecting rod 522 to rotate eccentrically. The gear connecting rod 522 drives the piston head 524 to reciprocate inside through the piston connecting rod 521. When the piston head 524 advances, it will squeeze the gas inside the air extraction housing 525. At this time, the air outlet valve at the connection between the air outlet pipe 527 and the air extraction housing 525 opens under the pressure, allowing the gas to be discharged. When the piston head 524 retreats, the cavity between the piston head 524 and the air extraction housing 525 becomes larger, generating a negative pressure. At this time, the air inlet valve at the connection between the air inlet pipe 526 and the air extraction housing 525 opens, sucking the gas in the air extraction box 542 into the air extraction housing 525. As a result, a negative pressure is generated in the air extraction box 542. The air extraction box 542 sucks the air in the dust suction box 541, generating a negative pressure in the dust suction box 541 and blocking the dust through the filter screen to prevent the dust from entering the air extraction housing 525 through the air extraction box 542. Repeating like this, a continuous suction force is generated in the dust suction box 541, sucking away the dust on the surface of the transmission outer tire 71, and also sucking the dust swept by the cleaning roller 543 into the dust suction box 541.

[0054] While the air extraction gear 523 rotates, it drives the cleaning gear 56 to rotate. The cleaning gear 56 drives the cleaning roller 543 to rotate through the cleaning rotating shaft 544. The cleaning roller 543 rotates in the opposite direction to the induction drive wheel 7. The bristles on the cleaning roller 543 and the transmission outer tire 71 rotate in opposite directions, and more quickly sweep off the dust on the transmission outer tire 71. The swept dust is sucked away by the dust suction box 541. At the same time, under the action of the dust suction box 541, the dust is more likely to fall off from the transmission outer tire 71. The cleaned transmission outer tire 71 will adsorb the dust on the flywheel, and then be cleaned again. Eventually, both the flywheel and the transmission outer tire 71 can be cleaned.
