Description

Technical Field

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

[0002] As the fitness craze continues to heat up in recent years, more and more people are engaged in fitness exercises. Power bicycles are widely promoted as a common fitness equipment. They use human power to drive the flywheel to rotate and use the flywheel inertia to provide adjustable resistance to meet the personalized exercise needs of different users. In order to avoid wasting energy, people gradually convert the kinetic energy generated by power bicycles into electrical energy storage through energy-saving power generation devices.

[0003] At present, traditional energy-saving power generation devices usually generate electricity by contacting a transmission wheel with a flywheel. The flywheel drives the transmission wheel to rotate through friction, and the transmission wheel drives the generator shaft to rotate to generate electricity. Although this method 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 power bicycle to shake for a long time, and the flywheel shakes with the power bicycle and drives the transmission wheel to shake. The shaking of the two produces displacement, which makes the gap between the transmission wheel and the flywheel larger, the contact surface is reduced, and even the contact surfaces are separated from each other, resulting in a significant reduction in power generation efficiency. Users are required to check and adjust frequently, which greatly reduces the practicality of the power generation device. Moreover, dust will accumulate on the surface of the flywheel and the surface of the transmission wheel after long-term use. The dust will reduce the friction of the contact surface between 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 technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an energy-saving power generation device for fitness equipment, comprising a base plate support, a power storage base and a bearing are installed on the base plate support, a positioning assembly is symmetrically and rotatably installed on the power storage base, a first electric telescopic rod is installed between the positioning assembly and the base plate support, a cleaning device is installed on the positioning assembly, a power generation rotating rod is rotatably installed between the positioning assemblies through a bearing, an induction transmission wheel is installed on the power generation rotating rod, a power generation assembly is installed on the power generation rotating rod, the power generation assembly is connected to the positioning assembly, the power generation assembly is connected to the power storage base through a wire assembly, and the first electric telescopic rod and the positioning assembly are both connected to the power storage base through the wire assembly.

[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 electric energy transmitted by the power generation components, and can also store energy for the power storage base through external charging. The power storage base provides electric energy for the first electric telescopic rod and the second electric telescopic rod. The control system is interconnected with the power bicycle control system and shares data.

[0007] First, install the base support near the power bicycle so that the induction drive wheel is aligned with the flywheel of the power bicycle. After that, the staff uses the control system to extend or retract the first electric telescopic rod. 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 assembly includes a positioning side plate, which is rotatably mounted on the power storage base. A groove is provided on one side of the positioning side plate, in which a second electric telescopic rod is mounted, a preload slider is mounted on the output shaft of the second electric telescopic rod, the preload slider is slidably connected to the positioning side plate, a bearing is mounted on the preload slider, a power generation rotating rod is mounted between the preload sliders via bearings, the preload slider on one side is connected to the power generation assembly, the preload slider on the other side is connected to the cleaning device, and the second electric telescopic rod is connected to the power storage base via a wire assembly.

[0009] Afterwards, the control system starts the second electric telescopic rod, and the second electric telescopic rod drives the preload slider to extend forward, and the preload slider drives the power generating rod to move through the bearing, and the power generating rod drives the induction transmission wheel to move, so that the induction transmission wheel is in close contact with the flywheel. Afterwards, the output shaft of the second electric telescopic rod extends further forward, so that the induction transmission wheel continues to move. At this time, the induction transmission wheel cannot continue to move due to the obstruction of the flywheel, so that the power generating rod cannot move either. Subsequently, the positioning slider connected to the power generating rod through the bearing, as well as the positioning slider and the anti-slip 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 preload spring, compresses the preload spring and continues to slide in the groove of the positioning side plate. The second electric telescopic rod moves until the preload spring is completely compressed, and the control system stops the second electric telescopic rod. At this time, the induction drive wheel is tightly fitted with the flywheel, and the preload spring is compressed to give a reverse thrust to the anti-slip block, so that the anti-slip block has a tendency to slide away from the sliding box, and the anti-slip block finally transmits the thrust to the induction drive wheel through the positioning slide bar, the positioning slide block, the bearing and the generating rotating rod, so that the induction drive wheel generates a preload force on the flywheel, thereby 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 action of the elastic force of the preload spring, the anti-slip 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 fit with the flywheel.

[0010] The preload 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 passes through the sliding box and is equipped with a positioning slider. The other end of the positioning slide rod is equipped with an anti-slip block. A preload spring is installed between the anti-slip 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 transmission wheel includes a transmission wheel, which is mounted on a power generation rod, a transmission outer tire is mounted on the transmission wheel, an induction ring is movably mounted on the transmission wheel, the induction ring is engaged with the transmission outer tire, a fixed rod is mounted inside the transmission wheel, a limit plate is mounted on the fixed rod, an induction plate is slidably mounted between the limit plates, a strip groove is provided on the induction plate, the fixed rod passes through the strip groove, a spring connecting plate is symmetrically mounted on the induction plate, a reset spring is mounted between the spring connecting plate and the inner wall of the transmission wheel, a piezoelectric element is mounted inside the transmission wheel, an induction contact is mounted on the induction plate, the induction contact corresponds to the position of the piezoelectric element, and a transmission gear is mounted on one side of the transmission wheel. The transmission outer tire is made of rubber or other materials with a high friction coefficient. Due to the characteristics of rubber, the transmission outer tire is easily contaminated with dust, and the dust on the flywheel is easily attached to the surface of the transmission outer tire.

[0012] When the user pedals the power bicycle, as the flywheel rotates, it drives the induction drive wheel to rotate, and the induction drive wheel drives the power generation component to generate electricity through the power generation rod. An extrusion pressure is generated on the contact surface between the induction drive wheel and the flywheel. Under the action of the extrusion pressure, the contact part between the transmission outer tire and the flywheel is squeezed and slightly deformed. The transmission outer tire is deformed and drives the transmission outer ring to squeeze the induction sheet. The induction sheet overcomes the elastic force of the reset spring and drives the induction contact to squeeze the piezoelectric element. After the piezoelectric element is compressed, it generates current and transmits it to the control system. The control system analyzes the pressure on the piezoelectric element through the current, thereby analyzing the extrusion pressure on the transmission outer tire, and judges the contact situation between the induction drive wheel and the flywheel according to the extrusion pressure. When the extrusion pressure is too small, the control system starts the positioning component and repeats the previous operation to apply a preload to the induction drive wheel. At the same time, the rotation speed of the induction drive wheel can be analyzed according to the interval time of the electrical signals transmitted by multiple piezoelectric elements. A short interval time indicates that the rotation speed of the induction drive wheel is fast, and vice versa.

[0013] The cleaning device includes a connecting plate, an exhaust assembly and an exhaust connecting piece. The connecting plate is connected to the positioning slider, a bearing is embedded on the connecting plate, the exhaust assembly is connected to the cleaning and dust collection assembly through the exhaust connecting piece, the cleaning and dust collection assembly is installed on the connecting plate, a cleaning connecting rod is installed on the cleaning and dust collection assembly, the exhaust assembly is rotatably connected to the cleaning connecting rod, a cleaning cylinder is installed on the connecting plate, and the output shaft of the cleaning cylinder is connected to the cleaning and dust collection assembly.

[0014] When the pressure data transmitted by the induction drive wheel is good, but the speed of the flywheel of the powered bicycle is significantly different from the monitored speed of the induction drive wheel, it proves that the friction between the flywheel and the induction drive wheel is reduced. At this time, the control system turns on the cleaning cylinder, and the output shaft of the cleaning cylinder pushes the dust box to slide forward. The exhaust shell connected to the dust box through the exhaust connector, and the exhaust gear connected to the dust box through the cleaning connecting rod, slide forward with the dust box, so that the exhaust assembly as a whole slides with the cleaning dust assembly. When the exhaust gear engages 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 box is located near the transmission outer tire, and the bristles on the cleaning roller in the dust box just contact with the transmission outer tire.

[0015] The suction component includes an suction shell and an suction gear. The suction shell is connected to the cleaning and dust collection component through an suction connecting piece. The suction gear is rotatably connected to the cleaning connecting rod. A gear connecting rod is eccentrically and rotatably installed on the suction gear. A piston connecting rod is rotatably installed at one end of the gear connecting rod. A piston head is rotatably installed at one end of the piston connecting rod. The piston head is slidably installed in the suction component. An air outlet pipe is installed at one end of the suction shell. A one-way opening and closing air outlet valve is provided at the connection between the air outlet pipe and the suction shell. An air inlet pipe is installed on the suction shell. A one-way opening and closing air inlet valve is provided at the connection between the air inlet pipe and the suction shell. One end of the air inlet pipe is communicated with the interior of the cleaning and dust collection component. The suction gear is meshed with the cleaning and dust collection component for transmission, and the connecting plate is slidably connected to the positioning side plate.

[0016] The transmission gear rotates with the induction transmission wheel, and the transmission gear drives the exhaust gear to rotate. The exhaust gear drives the gear connecting rod to rotate eccentrically. The gear connecting rod drives the piston head to slide back and forth through the piston connecting rod. When the piston head moves forward, it will squeeze the gas in the exhaust shell. At this time, the exhaust valve located at the connection between the exhaust pipe and the exhaust shell opens under the action of pressure to discharge the gas. When the piston head retreats, the cavity between the piston head and the exhaust shell becomes larger, generating negative pressure. At this time, the intake valve located at the connection between the intake pipe and the exhaust shell opens, and the gas in the exhaust box is sucked into the exhaust shell, thereby generating negative pressure in the exhaust box. The exhaust box sucks the air in the dust collection box, generating negative pressure in the dust collection box, and blocks the dust through the filter screen to prevent the dust from entering the exhaust shell through the exhaust box. This reciprocating process makes the dust collection box generate continuous suction, so that the dust on the surface of the transmission outer tire is sucked away, and the dust swept by the sweeping roller is sucked into the dust collection box.

[0017] The cleaning dust collection assembly includes a dust collection box and a cleaning shaft, which is rotatably installed in the dust collection box, one end of the cleaning shaft passes through the dust collection box and is installed with a cleaning gear, the cleaning gear is meshed with the exhaust gear for transmission, a cleaning roller is installed on the cleaning shaft, an exhaust box is installed on the dust collection box, the exhaust box is connected to the inside of the dust collection box, the air intake pipe is connected to the inside of the exhaust box, a filter is provided at the connection between the exhaust box and the dust collection box, a cleaning connecting rod is installed on the dust collection box, the dust collection box is installed on the connecting plate, the dust collection box is connected to the exhaust connecting piece, the cleaning roller is provided with bristles, and the dust collection box is connected to the output shaft of the cleaning cylinder.

[0018] When the vacuum gear rotates, it drives the cleaning gear to rotate. The cleaning gear drives the cleaning roller to rotate through the cleaning shaft. The cleaning roller rotates in the opposite direction to the induction drive wheel. The bristles on the cleaning roller rotate in the opposite direction to the drive tire and sweep the dust on the drive tire more quickly. The swept dust is sucked away by the dust collection box. At the same time, under the action of the dust collection box, the dust is more easily removed from the drive tire. The cleaned drive tire will absorb the dust on the flywheel, and then be cleaned again, so that both the flywheel and the drive tire can be cleaned in the end.

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

[0020] When the generating rod rotates, it drives the PMG auxiliary exciter to run and generate current, and energizes the rotor coil, causing the rotor coil to generate magnetic force, which drives the rotor coil to rotate through the rotor connector. The magnetic flux lines of the rotor coil are cut by the surrounding stator coil, causing current to be generated in the stator coil. The current enters the power storage base through the wire assembly and is stored in 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 drive wheel and the flywheel of the power bicycle to fit closely for transmission through the positioning component, and uses the preload slider to make the induction drive wheel generate a preload force on the flywheel, thereby 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 action of the elastic force of the preload spring, the anti-slip 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 contact with the flywheel, thereby improving the power generation efficiency.

[0022] The induction drive wheel converts the extrusion pressure it experiences into an electrical signal. The control system analyzes the extrusion pressure on the induction drive wheel through the current and determines the contact between the induction drive wheel and the flywheel based on the extrusion pressure. When the extrusion pressure is too small, the preload force of the induction drive wheel is adjusted through the positioning component to ensure that the induction drive wheel and the flywheel maintain good contact. At the same time, the speed detection of the induction drive wheel is achieved by analyzing the interval time of the electrical signals transmitted by multiple piezoelectric elements.

[0023] The flywheel is used to drive the induction drive wheel to rotate, thereby driving the operation of the exhaust component, and the exhaust component drives the cleaning and dust collection components to operate synchronously. The bristles on the cleaning roller rotate in the opposite direction to the transmission outer tire and sweep the dust on the transmission outer tire more quickly. The dust collection box generates continuous suction to suck away the dust on the surface of the transmission outer tire, and also makes the dust swept by the cleaning roller be sucked into the dust collection box, thus ensuring the cleanliness of the induction drive wheel and the flywheel, preventing the friction between the two from being reduced due to dust, and achieving the purpose of ensuring power generation efficiency through self-cleaning.

[0024] The induction drive wheel is used to drive the generating assembly, and the generating rod drives the PMG auxiliary exciter to operate and generate current, so that the rotor coil is energized to become an electromagnet. After that, the rotor rotates so that the magnetic flux lines are cut by the stator coil, and the stator coil generates current, thereby achieving the purpose of power generation. The electric energy transmitted by the generating assembly stored in the storage base can also be stored in the storage base through external charging.

[0025] The first electric telescopic rod is used to drive the positioning side plate to rotate, so as to realize automatic adjustment of the angle of the positioning side plate, thereby facilitating the subsequent contact between the induction transmission wheel and the flywheel.

[0048] When the generating rotor 8 rotates, it drives the PMG auxiliary exciter 65 to run and generate current, and energizes the rotor coil 64, so that the rotor coil 64 generates magnetic force, and drives the rotor coil 64 to rotate through the rotor connector 61. The magnetic flux lines of the rotor coil 64 are cut by the surrounding stator coil 62, so that current is generated in the stator coil 62. The current enters the power storage base 2 through the wire assembly and is stored in the power storage base 2.

[0049] The working principle of the present invention is as follows: first, the bottom plate support 1 is installed near the power bicycle, so that the induction transmission wheel 7 is aligned with the flywheel of the power bicycle, and then the staff extends or contracts the first electric telescopic rod 4 through the control system, and the output shaft of the first electric telescopic rod 4 drives the positioning side plate 31 to rotate, so that the end of the positioning side plate 31 is aligned with the center point of the flywheel of the power bicycle, such as Figure 1 As indicated by the arrow.

[0050] Afterwards, the control system starts the second electric telescopic rod 32, and the second electric telescopic rod 32 drives the preload slider 33 to extend forward, and the preload slider 33 drives the power generating rod 8 to move through the bearing 9, and the power generating rod 8 drives the induction transmission wheel 7 to move, so that the induction transmission wheel 7 is in close contact with the flywheel. Afterwards, the output shaft of the second electric telescopic rod 32 extends further forward, so that the induction transmission wheel 7 continues to move. At this time, the induction transmission wheel 7 cannot continue to move due to the obstruction of the flywheel, so that the power generating rod 8 cannot move either. Then, the positioning slider 331 connected to the power generating rod 8 through the bearing 9, as well as the positioning slider 333 and the anti-slip block 335 on the positioning slider 331 are all unable to move. Under the thrust of the second electric telescopic rod 32, the sliding box 332 overcomes the elastic force of the preload spring 334, compresses the preload spring 334 and continues to be in the groove of the positioning side plate 31 When the induction wheel 7 is displaced from the flywheel, the anti-slip block 335 will slide in the direction away from the sliding box 332, thereby driving the induction wheel 7 to move in the direction of the flywheel, thereby ensuring that the induction wheel 7 is always in contact with the flywheel.

[0051] When the user pedals the power bicycle, as the flywheel rotates, the induction transmission wheel 7 is driven to rotate, and the induction transmission wheel 7 drives the power generation component 6 to generate electricity through the power generation rotating rod 8. The contact surface of the induction transmission wheel 7 and the flywheel will generate an extrusion force. Under the action of the extrusion force, the contact part of the transmission outer tire 71 and the flywheel is squeezed and slightly deformed. The transmission outer tire 71 is deformed and drives the transmission outer ring to squeeze the induction sheet 75. The induction sheet 75 overcomes the elastic force of the reset spring 76 and drives the induction contact 77 to squeeze the piezoelectric element 78. The piezoelectric element 78 generates current after being compressed and is transmitted to the control system. The control system analyzes the pressure on the piezoelectric element 78 through the current, thereby analyzing the extrusion pressure on the transmission outer tire 71, and judges the contact between the induction transmission wheel 7 and the flywheel according to the extrusion pressure. When the extrusion pressure is too small, the control system turns on the positioning component 3, repeats the previous operation, and applies a preload force to the induction transmission wheel 7. At the same time, the rotation speed of the induction transmission wheel 7 can be analyzed according to the interval time of the electrical signals transmitted by multiple piezoelectric elements 78. A short interval time indicates that the rotation speed of the induction transmission wheel 7 is fast, otherwise, the rotation speed of the induction transmission wheel 7 is slow.

[0052] When the pressure data transmitted by the induction drive wheel 7 is good, but the speed of the flywheel of the power bicycle is significantly different from the monitored speed of the induction drive wheel 7, it proves that the friction between the flywheel and the induction drive wheel 7 is reduced. At this time, the control system turns on the cleaning cylinder 55, and the output shaft of the cleaning cylinder 55 pushes the dust box 541 to slide forward. The suction shell 525 connected to the dust box 541 through the suction connector 53, and the suction gear 523 connected to the dust box 541 through the cleaning connecting rod 57, slide forward together with the dust box 541, so that the suction assembly 52 as a whole follows the cleaning dust assembly 54 to slide. When the suction gear 523 is engaged with the transmission gear 711, the control system stops the retraction of the output shaft of the cleaning cylinder 55. At this time, the opening of the dust box 541 is located near the transmission outer tire 71, and the bristles on the cleaning roller 543 in the dust box 541 just contact with the transmission outer tire 71.

[0053] The transmission gear 711 rotates together with the induction transmission wheel 7, and the transmission gear 711 drives the air pumping gear 523 to rotate, and the air pumping gear 523 drives the gear connecting rod 522 to rotate eccentrically, and the gear connecting rod 522 drives the piston head 524 to slide back and forth through the piston connecting rod 521. When the piston head 524 moves forward, it squeezes the gas in the air pumping shell 525. At this time, the air outlet valve located at the connection between the air outlet pipe 527 and the air pumping shell 525 opens under the action of pressure to discharge the gas. When the piston head 524 retreats, the cavity between the piston head 524 and the air pumping shell 525 becomes larger, generating negative pressure At this time, the air intake valve located at the connection between the air intake pipe 526 and the exhaust shell 525 is opened, and the gas in the exhaust box 542 is sucked into the exhaust shell 525, so that the exhaust box 542 generates negative pressure, and the exhaust box 542 sucks the air in the dust box 541, so that the dust box 541 generates negative pressure, and blocks the dust through the filter to prevent the dust from entering the exhaust shell 525 through the exhaust box 542. This reciprocating process makes the dust box 541 generate continuous suction, so that the dust on the surface of the transmission outer tire 71 is sucked away, and the dust swept by the cleaning roller 543 is also sucked into the dust box 541.

[0054] When the exhaust 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 shaft 544. The cleaning roller 543 rotates in the opposite direction to the induction drive wheel 7. The bristles on the cleaning roller 543 rotate in the opposite direction to the transmission outer tire 71, and sweep the dust on the transmission outer tire 71 more quickly. The swept dust is sucked away by the dust collection box 541. At the same time, under the action of the dust collection box 541, the dust is more easily removed from the transmission outer tire 71. The cleaned transmission outer tire 71 will absorb the dust on the flywheel, and then be cleaned again, so that both the flywheel and the transmission outer tire 71 can be cleaned in the end.
