Description

Technical Field

[0001] The utility model belongs to the technical field of energy harvesting, and particularly relates to an energy harvesting device and a walking machine. Background Art

[0002] A walking machine is a kind of fitness equipment in the community. Its functions are to enhance cardiopulmonary function, lower limb and lumbar muscle strength, improve lower limb flexibility and coordination ability, and improve the stability of each joint of the lower limb. The user stands on the two pedals of the walking machine and controls the front and back movement of the two pedals to imitate walking so as to achieve the purpose of fitness. However, most of the existing walking machines only provide basic exercise functions and fail to fully collect and utilize the energy wasted during the fitness process. The publication number CN203060677U discloses a power-generating walking machine, which achieves the purpose of power generation by connecting a driven wheel and a driven shaft to a power generation motor through a power pedal. However, a series of power generation structures of this application are located outside the walking machine and occupy a large space. Therefore, there is a lack of a device that can minimize the occupied space, effectively convert the energy generated when using the walking machine, store the collected energy for other electrical devices near the walking machine, and conform to the current global trend of sustainable development and environmental protection. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides an energy harvesting device and a walking machine. When a user stands on the footrest and swings the pedal rod during movement, the pedal rod drives the rotating assembly of the energy harvesting device to rotate. The rotation of the rotating assembly drives the permanent magnet assembly to rotate, so that a displacement is generated between the permanent magnet assembly and the magnetoelectric coil, thereby generating electric energy, and the electric energy can be stored in the electric energy storage assembly. The collected energy can supply power to other electrical devices near the walking motor, avoiding waste of energy.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An energy harvesting device includes a housing, a rotating assembly, a permanent magnet assembly, a magnetoelectric coil assembly, and an electric energy storage assembly. The rotating assembly, the permanent magnet assembly, and the magnetoelectric coil assembly are all arranged inside the housing. One end of the rotating assembly can be connected to a pedal, the other end of the rotating assembly is connected to the permanent magnet assembly, the permanent magnet assembly is connected to the magnetoelectric coil assembly, and the other end of the magnetoelectric coil assembly penetrates through the housing and can be connected to a support frame.

[0006] Preferably, the rotating assembly includes an input shaft, the input shaft is rotationally connected to the housing through a first bearing. A connecting piece is sleeved at one end of the input shaft close to the permanent magnet assembly. The inner ring of the connecting piece is provided with a second bearing. The second bearing is a one-way bearing. A first rotating shaft is sleeved inside the inner ring of the second bearing. One end of the first rotating shaft away from the connecting piece is sleeved with a permanent magnet assembly.

[0007] Preferably, the connecting member is a first gear. A second gear is rotatably arranged on the first rotating shaft through a third bearing. The third bearing is a one-way bearing. The first gear and the second gear are arranged in a mirror image. Both the first gear and the second gear are bevel gears. The first gear and the second gear are simultaneously meshed through a sixth gear. The rotating shaft on the sixth gear is fixed to the inner wall of the housing through a bearing.

[0008] Preferably, the permanent magnet assembly includes a fifth gear, a fourth gear, and a plurality of third gears. The fifth gear is sleeved on one end of the first rotating shaft away from the connecting member. A plurality of permanent magnets are arranged on one side of the fifth gear away from the connecting member. The plurality of third gears are respectively meshed with the fifth gear. The plurality of third gears are circumferentially distributed along the outer edge of the fifth gear. The fourth gear is an internal gear fixed to the inner wall of the housing. The plurality of third gears are all meshed with the fourth gear. Third rotating shafts respectively penetrate through the centers of the plurality of third gears. One end of each third rotating shaft away from the rotating assembly is fixed to the magnetoelectric coil assembly.

[0009] Preferably, the magnetoelectric coil assembly includes a connecting disc and a second rotating shaft. One end of each third rotating shaft away from connecting the rotating assembly is fixed to the connecting disc. The plurality of third rotating shafts are fixed along the circumference of the connecting disc. A plurality of magnetoelectric coils are arranged on one side of the third rotating shaft fixed to the connecting disc. The plurality of magnetoelectric coils are respectively electrically connected to an electric energy storage assembly. The second rotating shaft is fixedly arranged on one side of the connecting disc away from the magnetoelectric coils. The second rotating shaft is rotatably connected to one side of the housing away from the input shaft through a fourth bearing.

[0010] A walking machine adopts the above energy collection device, and includes two groups of columns, pedal rods, and foot pedals arranged in a mirror image. An armrest is arranged between the columns. The energy collection device is arranged between the columns and the pedal rods.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0012] 1. When the user is using the walking machine, the user stands on the foot pedal. When exercising, the pedal rod swings, and the pedal rod drives the rotating assembly of the energy collection device to rotate. The rotation of the rotating assembly drives the permanent magnet assembly to rotate, so that a displacement is generated between the permanent magnet assembly and the magnetoelectric coil, thereby generating electric energy, and the electric energy can be stored in the electric energy storage assembly. The collected energy can supply power to other electrical devices near the walking motor, avoiding waste of energy.

[0013] 2. When the pedal swings clockwise, it drives the input shaft to rotate clockwise. The input shaft drives the first gear to rotate clockwise. The first gear drives the sixth gear to rotate counterclockwise. The sixth gear drives the second gear to rotate counterclockwise. The second gear drives the third bearing to rotate counterclockwise. The third bearing drives the first rotating shaft to rotate counterclockwise. The first rotating shaft drives the fifth gear to rotate counterclockwise. At this time, since the locking directions of the second bearing and the third bearing are opposite, the inner and outer rings of the second bearing can rotate relative to each other. Therefore, the first gear does not drive the second bearing to rotate, and thus does not affect the rotation of the first rotating shaft that is in interference fit with the inner ring of the second bearing;

[0014] When the pedal swings counterclockwise, it drives the input shaft to rotate counterclockwise. The input shaft drives the first gear to rotate counterclockwise. The first gear drives the second bearing to rotate. The second bearing drives the first rotating shaft to rotate counterclockwise, thereby driving the fifth gear to rotate counterclockwise. At this time, since the locking directions of the second bearing and the third bearing are opposite, the inner and outer rings of the third bearing can rotate relative to each other. Therefore, the rotation of the second gear does not drive the third bearing to rotate and does not interfere with the rotation of the first rotating shaft. Therefore, the first rotating shaft still rotates counterclockwise;

[0015] After converting the bidirectional rotation of the pedal into the counterclockwise rotation of the fifth gear through the rotating assembly, the fifth gear drives the third gear to rotate. The third gear drives the third rotating shaft to rotate, thereby driving the permanent magnet assembly and the magnetoelectric coil assembly to cooperate with each other to generate electric energy. Through the design of the rotating assembly, the bidirectional swing of the pedal can be converted into the unidirectional rotation of the first rotating shaft and the third rotating shaft, and electric energy can be continuously generated when the pedal swings clockwise and counterclockwise, improving the power generation efficiency.

[0016] 3. The permanent magnet is installed on the fifth gear, and the magnetoelectric coil is installed on the connecting disc. Since the fifth gear and the third gear rotate in opposite directions, the fifth gear and the connecting disc rotate in opposite directions, which can make the permanent magnet and the magnetoelectric coil rotate in opposite directions. Compared with the fixed permanent magnet, the number of times the magnetoelectric coil cuts the magnetic induction lines of the permanent magnet per unit time doubles, which can significantly improve the power generation efficiency. Moreover, the magnetoelectric coil and the permanent magnet are compressed in a relatively small space, saving the space occupied by the entire energy collection device and reducing the volume of the energy collection device.

[0017] 4. By setting the first gear and the second gear as bevel gears, and setting the sixth gear to mesh with the first gear and the second gear, compared with other structures that transmit force through cylindrical gears, the bevel gear structure set in this application can reduce the space occupied between the gears, save the space occupied by the entire energy collection device, and reduce the volume of the energy collection device.

[0018] 5. The rotating assembly, the permanent magnet assembly, and the magnetoelectric coil assembly are firmly fixed in the housing. The input shaft and the second rotating shaft use corresponding bearings relative to the housing, enabling the input shaft, the second rotating shaft, and the sixth gear to rotate smoothly relative to the housing, reducing energy loss caused by friction and wear between components, and improving the overall mechanical efficiency and service life of the device.

[0019] 6. The electric energy output by the magnetoelectric coil assembly can be stored in the electric energy storage assembly, and the electric energy storage assembly can be fixed on the housing.

[0020] 7. A stable foot pedal unit is formed. The swinging of the foot pedal drives the rotation of the input shaft, thereby driving the entire energy collection device to work and collecting the residual energy generated when the user exercises. The dense texture design on the foot pedal can prevent the user's feet from slipping during exercise, improving the safety of the device.

[0021] 8. The upright column, the pedal rod, the foot pedal, and the handrail form a set of stable fixing frames to support the entire walking machine device and bear the weight of the user. The handrail provides support for the user during exercise to prevent loss of balance. BRIEF DESCRIPTION OF THE DRAWINGS
