Description

Technical Field

[0001] The utility model relates to the field of power generation devices, in particular to a human-powered power generation device and a pulling fitness device. Background Art

[0002] In some related technologies, the main operating modes of human-powered power generation devices can be divided into hand-cranking mode and foot-operated mode. The hand-cranking power generation device is more common due to its relatively compact structure and ease of use.

[0003] However, the output power of hand-cranked generators is generally low, ranging from a few watts to 20 watts, making it difficult to maintain a high output power (e.g., 20 watts or above). This is primarily due to the inherent design of hand-cranked generators, which rely on the user's arm to rotate the crank, thereby driving the internal generator module to generate electricity. Based on the external structure of existing hand-cranked generators, the muscles involved in their use are primarily the forearm muscles (such as the brachioradialis, flexor carpi radialis, and flexor carpi ulnaris) for force generation, the shoulder muscles (such as the deltoid and rotator cuff) for stability, and the back muscles (such as the latissimus dorsi, trapezius, and rhomboids) for stability. However, according to human anatomy, the muscles used to rotate the crank are primarily responsible for more precise and intricate movements such as grasping, twisting, and controlling finger, thumb, and wrist movements, rather than for generating power for actions that require higher power, such as moving, pushing, and pulling.

[0075] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments use associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core part of the present application being overwhelmed by too much description. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0076] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0077] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0078] In the embodiments of this application, the human-powered power generation device uses a pull cord to drive a pulley to generate electricity. This allows users to achieve power generation through different postures and by utilizing more muscle groups, creating conditions for high-power generation. Furthermore, regarding the rewinding of the pulley, compared to coil springs used in similar applications, the elastic colloid in the embodiments of this application relies on twisting and deformation to provide the rewinding force for the pull cord, which helps avoid noise. Unlike coil springs, the force required when the degree of curling is high does not significantly increase, which helps reduce power loss, facilitates high power generation, and provides a more stable rope-pulling process.

[0079] In addition to simply generating electricity, the human-powered power generation device in the embodiments of the present application can also be used as a tension resistance generator for a tension fitness device due to its use of a pull rope, enabling tension training. The tension fitness device provides tension resistance to the pull rope, requiring the user to pull the rope with a certain amount of force to achieve muscle training. Different pulling postures can be used to train different muscle groups. Compared to using counterweights or electric motors to provide tension resistance, counterweights take up more space and are bulky. While electric motors can be compact and lightweight, they consume electricity during operation, which can be inconvenient to use regardless of whether they are rechargeable or powered by an external power supply. Using the human-powered power generation device in the present application to provide tension resistance not only reduces space requirements and consumes no electricity, but also generates electricity, making it easy to install in offices, homes, and other places, allowing people to exercise at home or in the office, eliminating the need for a dedicated gym. The tension resistance can also be easily adjusted by controlling the operating current of the load or energy storage unit connected to the power generation unit.

[0080] Embodiments of the human-powered power generation device of the present utility model:

[0081] In one embodiment, please refer to Figures 1 to 3 The main body of the human-powered power generation device is cylindrical and includes a device housing. The device housing may include a junction box 110 located at the bottom of the human-powered power generation device, and a power generation unit housing 120, a rope unit housing 130, and a rewinding unit housing 140 sequentially arranged above the junction box 110. The rope unit housing 130 may include a first housing 131 and a second housing 132 to facilitate the assembly of the rope unit. Please refer to Figure 4 A power generation unit 200, a rope pulling unit 500 and a reverse winding unit 600 are provided in the device shell.

[0082] The power generation unit 200 includes a power input member 210. The power generation unit 200 is used to convert the rotational kinetic energy input by the power input member 210 into electrical energy. Rotational kinetic energy is the kinetic energy generated by the rotation of an object. The pull rope unit 500 includes a pulley 510 and a pull rope 520. The pull rope 520 has a fixed end fixedly connected to the pulley 510 and a pulling end for the user to pull. When pulled, it can drive the pulley 510 to rotate. A one-way transmission structure 400 is provided between the pulley 510 and the power input member 210. When the pulley 510 rotates in a first direction, the one-way transmission structure 400 is used to drive the power input member 210 to rotate. When the pulley 510 rotates in an opposite second direction, the one-way transmission structure 400 stops driving the power input member 210. The reverse winding unit 600 includes an elastic colloid 610 and a pulling seat 620. The pulling seat 620 is positioned on the device housing and is spaced apart from the rope pulley 510 along the axial direction of the rope pulley 510. The elastic colloid 610 is connected between the pulling seat 620 and the rope pulley 510. When the power input member 210 rotates in a first direction, the elastic colloid 610 is twisted and deformed, accumulating elastic force. This elastic force is used to drive the rope pulley 510 to rotate in a second direction when the pulling rope 520 is released. With this structure, a user can input energy into the human-powered power generation device by pulling the pulling rope 520 to generate electricity. The reverse winding unit 600 then rewinds the pulling rope 520, meeting repeated pulling requirements.

[0083] The structure and function of each component will be introduced in detail below.

[0084] It should be noted that, in some embodiments, the human-powered power generation device may further include a speed change unit 300 for realizing speed-changing transmission, which is used to realize speed-increasing transmission from the pulley 510 to the power generation unit 200, and can increase the rotation speed of the power input part 210 of the power generation unit 200, so that the power generation unit 200 operates in the high-efficiency power generation range, which is conducive to achieving greater power generation power.

[0085] In order to more clearly illustrate the specific embodiments of the present invention, the present application describes the embodiments in terms of the upper, lower, front, and rear positions shown in the figures. Of course, those skilled in the art will understand that the orientations defined in the embodiments are merely examples to more clearly illustrate the positional relationships between the various components, and do not limit the embodiments of the present invention to being arranged in this manner.

[0086] The connection method between the above-mentioned junction box 110, power generation unit housing 120, rope pull unit housing 130 and rewind unit housing 140 is not limited. For example, it can be flange connection, riveting, threaded connection, and radial positioning can be achieved by plug-in connection and fixed by fasteners. Those skilled in the art can choose the corresponding connection method according to the specific structure. In order to avoid the structure shown in the figure being too complicated and affecting the expression of the core solution, the figure does not fully reflect the specific assembly structure between the various parts of the device housing. In addition, in some other embodiments, the device housing of the human-powered power generation device can also be other shapes, such as a square box shape, a round box shape, etc.

[0087] The power generation unit 200 is fixed in the power generation unit housing 120, and its specific type is not limited, for example, it can be an AC generator or a DC generator. The specific structure of the power generation unit 200 can refer to the existing structure in the relevant technology. Considering that it has no direct relevance to the innovative content of this application and the technical problems to be solved, it will not be described here. The main part of the power generation unit 200 is fixed on the power generation unit housing 120, and the power input part 210 can be an input shaft, which can be a solid shaft or a hollow shaft. Those skilled in the art can understand that in some other embodiments, the power input part 210 of the power generation unit 200 can also be the main part, and the input shaft can be fixed on the power generation unit housing 120. That is, by replacing the stator and the rotor of the power generation unit 200, the relative rotation between the stator and the rotor can also be achieved.

[0088] In order to transmit the electric energy generated by the power generation unit 200 to the outside, in one embodiment, please refer to Figure 4 , a wire threading hole 121 is provided on the bottom wall of the power generation unit housing 120, and the wire threading hole 121 is connected to the junction box 110. The power generation unit 200 can be connected to a cable, and the cable passes through the wire threading hole 121 into the junction box 110 and is connected to the connector 220 at the bottom of the junction box 110. The above-mentioned connector 220 forms the power output end of the power generation unit 200, and other electrical components can be connected to the connector 220, and the power supply is achieved by relying on the power generation unit 200. The provision of the junction box 110 and the connector 220 is conducive to improving the appearance and is also convenient for adapting to different electrical components. Those skilled in the art will understand that in some other embodiments, the junction box 110 can also be omitted, for example, the transmission of electric energy can be achieved directly through the cable led out from the power generation unit 200, and the lead-out position of the cable can also be set on the upper part or outer peripheral surface of the device shell.

[0089] The power generation unit 200 generates heat during operation. To ensure stable operation of the power generation unit 200 , heat dissipation holes 122 may be provided on the outer wall of the power generation unit housing 120 .

[0090] The power input member 210 (input shaft) of the power generation unit 200 passes through the opening on the bottom wall of the rope unit housing 130 and is connected to the speed change unit 300. The bottom of the speed change unit 300 is provided with an output shaft 320, and the output shaft 320 is provided with a plug hole. The plug hole is for the power input member 210 of the power generation unit 200 to be inserted and limited along the circumferential direction to achieve power transmission. Those skilled in the art should know that power transmission between the input shaft of the power generation unit 200 and the speed change unit 300 in this application can be achieved through any form, such as a flat key, spline, coupling, flange, etc., or a planar structure can be provided on the outer surface of the input shaft, and the plug hole can be set to a matching shape to achieve power transmission by relying on the planar structure.

[0091] There is no limitation on the fixing method of the speed change unit 300 on the device housing. In a specific embodiment, a connecting flange is provided at the bottom of the speed change unit 300, and the speed change unit 300 is fixed to the rope unit housing 130 through the connecting flange.

[0092] The speed change unit 300 can be modular, or the device housing can be used as a mounting base to assemble various components, each of which forms the speed change unit. In one embodiment, the speed change unit 300 can utilize a planetary reducer, achieving increased speed by reversing the input shaft 310 and output shaft 320. To achieve increased speed and a larger transmission ratio, the output shaft 320 can be connected to the sun gear of the planetary gear train and connected to the input shaft of the power generation unit 200. The ring gear is fixed relative to the device housing, and the planet carrier, serving as the input component of the speed change unit 300, can be connected to the input shaft 310.

[0093] The input shaft 310 and the output shaft 320 of the speed change unit 300 are coaxially arranged. The input shaft 310 is coaxially connected to the pulley 510, and the output shaft 320 is coaxially connected to the power input member 210 of the power generation unit 200, which is beneficial to improving transmission efficiency and achieving higher power generation.

[0094] Those skilled in the art will appreciate that in some other embodiments, the speed change unit 300 may be replaced with other forms, such as a fixed-axis gear transmission. When a planetary gearbox is used, a planetary gearbox with two or more stages may also be used.

[0095] In one embodiment, the rope pulley 510 of the rope pulling unit 500 is rotatably assembled in the rope pulling unit housing 130, and a wheel groove 511 is provided on the rope pulley 510. The wheel groove 511 can be used for the pulling rope 520 to be wound and the pulling rope 520 is positioned along the axial direction of the rope pulley 510. The pulling rope 520 can be made of a belt body with a roughly rectangular cross-section. The width of the belt body matches the width of the wheel groove 511, which has better tensile strength and stability. In some other embodiments, the rope pulley 510 can also omit the wheel groove 511, and the pulling rope 520 can also adopt other cross-sectional shapes, such as circular, square, etc. The fixed end of the pulling rope 520 can be fixedly connected to the rope pulley 510 in any way, such as bonding, clamping, fastening with fasteners, etc.

[0096] Those skilled in the art will appreciate that in order for the user to operate the pulling rope 520, the pulling end of the pulling rope 520 needs to extend outside the device housing. Figure 5 A rope through-hole 1311 is provided on the sidewall of the rope unit housing 130. The direction of the rope through-hole 1311 extending through the rope unit housing 130 corresponds to the outer circumference of the rope pulley 510 and is substantially tangential to the circumferential surface corresponding to the bottom wall of the wheel groove 511, thereby reducing friction between the pull rope 520 and the device housing. In other embodiments, the rope through-hole 1311 can also be provided at other locations within the device housing. Friction between the pull rope 520 and the device housing can be reduced by providing a curved surface or roller at the inner opening of the rope through-hole 1311.

[0097] In order to facilitate the user to operate the pulling rope 520, in one embodiment, the pulling end of the pulling rope 520 is connected to a pull ring 530, and the pull ring 530 can be a pull ring of fixed shape or a pull ring that can be flexibly deformed. Figure 10 The pull ring 530 includes a rotating shaft portion 533 arranged parallel to the axis of the pulley 510. A rotatable sleeve 534 is mounted on the rotating shaft portion 533 for the user to grasp. The rotatable sleeve 534 prevents the user's wrist from being hooked when the direction of force applied to the pull ring 530 changes, making it more comfortable to use, preventing injury to the user's hand, and maintaining stable power generation.

[0098] In order to facilitate the installation of the rotating sleeve 534, in one embodiment, please refer to Figure 10The pull ring 530 is an isosceles trapezoidal structure. The pull ring 530 includes a first half ring 531 and a second half ring 532 which are symmetrically arranged along the line connecting the midpoints of the two bottoms of the isosceles trapezoid. The first half ring 531 and the second half ring 532 are butt-jointed along the axial direction of the rope pulley 510. The first butt joint ends of the first half ring 531 and the second half ring 532 are simultaneously inserted into the rope body fixing seat 536, and the rope body fixing seat 536 is fixedly connected to the pulling rope 520; the second butt joint ends of the first half ring 531 and the second half ring 532 have an overlapping section, and a ring body fixing screw 537 is passed through the overlapping section. The ring body fixing screw 537 is used to fix the second butt joint end, and a screw through-hole for installing the ring body fixing screw 537 is provided on the rotating sleeve 534, which can conveniently realize the fixation of the first half ring 531 and the second half ring 532.

[0099] When assembling the pull ring 530, the first butt ends of the first and second half rings 531, 532 are respectively inserted into the insertion holes on the rope fixing base 536. The second butt ends of the first and second half rings 531, 532 are respectively inserted into the support end plates 535 at the axial ends of the rotating sleeve 534. The first and second butt ends of the first and second half rings 531, 532 are then fixed with screws to secure the entire pull ring 530. A removable cover 5343 can be provided over the screw holes on the rotating sleeve 534 to prevent it from affecting the gripping feel. Furthermore, in some embodiments, the rotating sleeve 534 can include an inner support sleeve 5341 and an outer protective sleeve 5342, with the outer protective sleeve 5342 providing a better feel and appearance.

[0100] In order to facilitate the flexible rotation of the rotating sleeve 534, please refer to Figure 10 The rotating sleeve 534 can be rotatably assembled on the rotating shaft portion 533 through the pull ring bearing 538. Considering the installation of the pull ring bearing 538, the outer diameter of the second butt end is not larger than the inner ring diameter of the pull ring bearing 538. The pull ring bearing 538 can be sleeved on the rotating shaft portion 533 through the second butt ends of the first half ring 531 and the second half ring 532.

[0101] The pulling rope 520 and the rope fixing base 536 can be fixedly connected in any manner. For example, rope connecting screws can be passed through both the pulling rope 520 and the rope fixing base 536, and the pulling rope 520 and the rope fixing base 536 can be fixedly connected by the rope connecting screws. Of course, the pulling rope 520 and the rope fixing base 536 can also be fixedly connected by crimping, clamping, hot melting, etc.

[0102] Please refer to Figure 4In one embodiment, a housing cavity 512 is provided in the radially central portion of the sheave 510. The housing cavity 512 forms an opening on the lower end surface of the sheave 510, and at least a portion of the speed change unit 300 is embedded in the housing cavity 512. To achieve the rotational assembly of the sheave 510, in one specific embodiment, a wheel body rotating shaft 513 is provided at the upper end of the sheave 510. The wheel body rotating shaft 513 can be a solid shaft or a hollow shaft, and is used to mount an upper bearing 541. The lower end of the sheave 510 is provided with a cylindrical portion 515. The cylindrical portion 515 is used to mount a lower bearing 542 and can form an avoidance passage to allow the speed change unit 300 to enter the housing cavity 512.

[0103] The first shell 131 and the second shell 132 of the rope pull unit housing 130 are respectively provided with an upper bearing seat and a lower bearing seat for mounting the upper bearing 541 and the lower bearing 542. Those skilled in the art should know that an axial positioning structure, such as a positioning step, can be provided on the upper bearing seat and the lower bearing seat to achieve axial and radial positioning of the rope pulley 510. The rope pull unit housing 130 adopts the form of a split first shell 131 and a second shell 132, which can facilitate the installation of the speed change unit 300 and the rope pulley 510. For example, the speed change unit 300 and the rope pulley 510 can be installed in sequence on the first shell 131, and then the second shell 132 is installed. The upper bearing 541 and the lower bearing 542 can be first installed on the rope pulley 510 and then assembled with the corresponding bearing seats.

[0104] A one-way transmission structure 400 is provided between the sheave 510 and the input shaft 310 of the speed change unit 300. The structural form of the one-way transmission structure 400 is not limited. For example, it can be formed by at least one of a one-way bearing, a one-way clutch, and a ratchet structure. The one-way clutch can adopt a friction one-way clutch, a roller one-way clutch, etc. The specific structure of the one-way transmission structure 400 can refer to the existing structures in the relevant technology. Considering that it has no direct relevance to the innovative content of this application and the technical problems to be solved, it will not be described here. A transmission component mounting portion is provided at the top of the accommodating cavity 512 on the sheave 510, and the transmission component mounting portion is used to install the one-way transmission structure 400. In some other embodiments, the sheave 510 and the speed change unit 300 can also be arranged in sequence along the axial direction of the sheave 510.

[0105] In one embodiment, the pulling seat 620 in the reverse winding unit 600 is positioned on the top of the device housing, for example, it can be supported on the device housing. Figure 4 and Figure 5 A positioning groove 141 is provided on the top end surface of the rewinding unit housing 140 , and the pulling seat 620 is installed in the positioning groove 141 , which can achieve positioning in a direction perpendicular to the axis of the rope pulley 510 .

[0106] In one embodiment, a first hanging member 514 is provided on the top surface of the rope pulley 510. The pulling seat 620 may include a disc-shaped main portion and a second hanging member 621 that protrudes downward from the axis of the main portion. The elastic colloid 610 may be annular and is pulled by the first hanging member 514 and the second hanging member 621. Both the first hanging member 514 and the second hanging member 621 may be hooks, which can prevent the elastic colloid 610 from detaching, thereby improving reliability.

[0107] The material of the elastic colloid 610 can be selected according to performance requirements, for example, it can be rubber, silicone, etc. For example, the annular elastic colloid 610 can be made of a rubber band. In order to achieve higher rebound performance and service life, the rubber band can be an industrial rubber band. For example, in some embodiments, the thickness of the elastic colloid is not less than 1 mm and the width is not less than 3 mm. In actual use, since the forward and reverse rotation frequency of the pulley 510 is relatively high, the elastic colloid 610 can be considered to be replaced after being used for a long time to achieve a better user experience. In order to facilitate replacement, an operating hole 142 is provided on the wall of the installation cavity on the device housing for accommodating the elastic colloid 610. The operating hole 142 is set corresponding to the interval between the pulling seat 620 and the pulley 510, so that the elastic colloid 610 can be replaced without disassembling the rewinding unit housing 140.

[0108] In some other embodiments, the elastic colloid 610 between the pulling seat 620 and the rope pulley 510 can also be replaced with other structural forms. For example, the elastic colloid 610 can be a rod-shaped structure, and its cross-sectional shape is not limited. For example, the cross-sectional shape can be circular, elliptical, rectangular, regular polygonal, etc. In addition, the two ends of the elastic colloid 610 can be provided with annular hanging holes to be respectively hung on the rope pulley 510 and the pulling seat 620, or fixed to the rope pulley 510 and the pulling seat 620 by screws. It can also be clamped and fixed by a clamping member provided on the pulling seat 620 and / or the rope pulley 510. In this case, the elastic colloid 610 can also be a sheet-like structure. In some embodiments, the clamping member can be two clamping plates, and a bolt can be provided between the two clamping plates. By tightening the bolt, the two clamping plates can be brought closer to each other, thereby clamping the portion of the elastic colloid 610 located between the two clamping plates. It should be noted that the size of the elastic colloid 610 can be selected as needed.

[0109] In some other embodiments, the first hanging member 514 and the second hanging member 621 can also be replaced with other structural forms, for example, a T-shaped structure, including a connecting column arranged along the axis of the rope pulley 510 and a hanging rod perpendicularly connected to the end of the connecting column, the hanging rod including a first rod body and a second rod body located on both sides of the connecting column, used to connect the elastic colloid 610; the corresponding elastic colloid 610 can be set at two locations, and when the pulling rope 520 is fully rewound, the two elastic colloids 610 can be parallel to the axial direction of the rope pulley 510, or arranged in an X-shaped cross, that is, the lower end is connected to the first side of the hanging rod of the first hanging member 514, and the upper end is connected to the second side of the hanging rod of the second hanging member 621. In order to prevent the elastic colloid 610 from slipping, grooves can be provided on the first hanging member 514 and the second hanging member 621 for the hanging parts of the elastic colloid 610 to be embedded.

[0110] In some embodiments, the pull seat 620 is rotatably mounted on the device housing, and its position during rotation is adjustable to change the pre-twist amount of the elastic body 610. Thus, before pulling the pull cord 520, the elastic body 610 can be pre-tightened by rotating the pull seat 620 to achieve a preload effect.

[0111] In a specific embodiment, please refer to Figure 6 、 Figure 7 The device housing has a first end surface 143, and the pulling seat 620 has a second end surface 622. The first end surface 143 and the second end surface 622 are arranged opposite each other along the axial direction of the rope pulley 510. The first end surface 143 has positioning protrusions 144, which are evenly distributed along the circumference. The second end surface 622 has positioning recesses 624 (for example, which can be blind holes or through holes) evenly distributed along the circumference. The positioning recesses 624 are for the positioning protrusions 144 to be inserted into to determine the rotation position of the pulling seat 620 and prevent the pulling seat 620 from rotating in the opposite direction under the elastic force of the elastic colloid 610. The positioning recesses 624 can also be evenly distributed along the circumference, and the number can be the same as the positioning protrusions 144.

[0112] It should be noted that the number and specific arrangement of the positioning protrusions 144 and positioning recesses 624 are not limited, as long as they can achieve the desired adjustment of the rotational position of the pulling seat 620. In some other embodiments, the positioning protrusions 144 and positioning recesses 624 can be arranged non-uniformly around the circumference, in which case the positioning position of the pulling seat 620 can be adjusted by rotating the entire circumference. In some other embodiments, the number of positioning recesses 624 can be an integer multiple of the number of positioning protrusions 144, enabling more precise adjustment of the elastic force. Alternatively, the number of positioning protrusions 144 can be one.

[0113] In order to facilitate the positioning protrusion 144 to be smoothly embedded in the positioning recess 624, the top surface of the positioning protrusion 144 can be a hemispherical surface, and the bottom surface of the blind hole can also be an adaptive hemispherical surface, which can also reduce the scratching of the positioning protrusion 144 on the second end surface 622.

[0114] In some other embodiments, the recess on the second end surface 622 may also be a through hole, which can be used for the positioning protrusion 144 to be embedded in. Of course, in some other embodiments, the positioning protrusion 144 may also be provided on the second end surface 622, and the positioning recess 624 may be provided on the first end surface 143.

[0115] When the elastic force of the elastic colloid 610 needs to be adjusted, the pulling seat 620 can be lifted up to disengage the positioning protrusion 144 from the positioning recess 624, and then the pulling seat 620 can be rotated. The rotation angle can be the corresponding angle between two adjacent positioning protrusions 144 (that is, the angle between the line connecting one of the positioning protrusions 144 and the rotation axis of the traction seat 620 and the line connecting the other adjacent positioning protrusion 144 and the rotation axis of the traction seat 620), or an integer multiple of the angle. Then, the traction seat 620 is released downward to embed the positioning protrusion 144 into different positioning recesses 624, thereby realizing the change of the rotational positioning position of the traction seat 620, and the elastic force adjustment of the elastic colloid 610 can be realized.

[0116] In some other embodiments, please refer to Figure 8 and Figure 9 The positioning protrusion 144 on the first end surface 143 can also be a support block having an inclined guide surface 1441. For example, the cross-section of the support block can be a right-angled trapezoid. The inclined guide surface 1441 can be provided on one side of the support block along the circumference of the rope pulley 510, and a blocking surface 1442 can be provided on the other side of the support block along the circumference of the rope pulley 510. The inclined guide surface 1441 corresponds to the slanted waist of the right-angled trapezoid, and the blocking surface 1442 corresponds to the straight waist of the right-angled trapezoid. At the same time, the positioning recess 624 on the second end surface 622 can be an adapter groove that matches the shape of the positioning protrusion 144. The adapter groove has a sloped surface 6241 that matches the inclined guide surface 1441 and a limiting surface 6242 that matches the blocking surface 1442. When the pulling seat 620 is rotated, the pulling seat 620 can be lifted up by cooperating with the inclined guide surface 1441 and the slope 6241 until the positioning protrusion 144 is completely separated from the positioning recess 624; continue to rotate the pulling seat 620, and the positioning protrusion 144 on the pulling seat 620 can move to the next adjacent positioning recess 624 or other positioning recess 624, and automatically embed into the corresponding positioning recess 624 by relying on the pulling force of the elastic colloid 610, thereby realizing the elastic force adjustment of the elastic colloid 610. During the adjustment process, there is no need to pull up the pulling seat 620 by applying axial force. The positioning position can be adjusted by simply rotating the pulling seat 620, which is more convenient to use.

[0117] In some embodiments, the side of the positioning protrusion 144 facing the second end surface 622 may be a support plane, facilitating a more stable support on the second end surface 622. In some other embodiments, the positioning protrusion 144 may also have a triangular structure, and the side of the positioning protrusion 144 facing the second end surface 622 may be pointed. Furthermore, in some other embodiments, the positioning protrusion 144 may be provided on the second end surface 622, and the positioning recess 624 may be provided on the first end surface 143.

[0118] In some other embodiments, the rotational positioning position of the pulling seat 620 can also be adjusted through other structures. For example, a set screw can be provided on the side wall of the positioning groove 141, and the set screw can be used to press against the outer peripheral surface of the pulling seat 620, thereby fixing the pulling seat 620 after it is rotated to a new position. In another example, a positioning protrusion can be provided on one of the side wall of the positioning groove 141 and the outer peripheral surface of the pulling seat 620, and a positioning recess can be provided on the other. During adjustment, the pulling seat 620 is pulled up to separate the positioning protrusion from the positioning recess. After rotating the pulling seat 620 to the new position, the positioning protrusion and the positioning recess are then engaged along the axial direction of the pulling seat 620. This can also adjust the rotational positioning position of the pulling seat 620.

[0119] In one embodiment, if Figure 6 and Figure 7 The device housing includes a housing body and a first pad 145, which is positioned on the housing body. The pulling seat 620 includes a seat body and a second pad 623, which is positioned on the seat body. The first end surface 143 is disposed on the first pad 145, and the second end surface 622 is disposed on the second pad 623. First protrusions 1451 are circumferentially distributed on the bottom surface of the first pad 145. The first protrusions 1451 can be inserted into the housing groove 146 on the rewind unit housing 140 to achieve the positioning of the first pad 145. Second protrusions 6231 are circumferentially distributed on the top surface of the second pad 623. The second protrusions 6231 can be inserted into the seat body groove 625 on the pulling seat 620 to achieve the positioning of the second pad 623. In some other embodiments, the first pad 145 and the second pad 623 may also be positioned in other ways, such as by fixing them on the shell body with screws, or by positioning them circumferentially on the shell body through a positioning plane on the outer periphery of the first pad 145.

[0120] The first pad 145 and the second pad 623 are provided to facilitate the molding of the positioning protrusion 144 and to facilitate replacement of the positioning protrusion 144 after wear. The first pad 145 and the second pad 623 can be made of plastic, which is low in cost and easy to process into an adaptive shape.

[0121] In one embodiment, the rewind unit housing 140 is fixed to the rope pulling unit housing 130 by flanges and bolts. The rewind unit housing 140 can be removed by removing the bolts, thereby realizing the disassembly and assembly of the first pad 145 and the second pad 623.

[0122] When the user pulls the pull cord 520, the human-powered generator needs to be connected to a corresponding fixed object to balance the pulling force of the pull cord 520. The fixed object can be any object, such as a table, a wall, etc. The human-powered generator can be fixed in any manner, for example, it can be hung on a fixed object via a hanging ring, or the device housing can be provided with a flange and connected to the fixed object by screws.

[0123] In one embodiment, please refer to Figure 11 The device housing is connected to a device connection base 700, which includes a sliding sleeve portion 710. The sliding sleeve portion 710 is used to be movably mounted on the corresponding guide column 800, which can change the position of the human power generation device on the guide column 800 to conveniently meet different usage requirements. The device housing and the device connection base 700 can be an integrated structure or a separate structure. The structure of the above-mentioned guide column 800 is not limited, for example, it can be as follows Figure 11 The profile shown can adopt a common structure as shown in the figure, with four sides, each of which is provided with a profile slot 802. In some other embodiments, the guide post 800 can also be a solid post, a hollow post, etc., and the cross-section can be circular, elliptical, regular polygonal, etc. During use, the guide post 800 can be fixed to a table, wall, or other fixed object to serve as a positioning function for the device connector 700.

[0124] In some other embodiments, please refer to Figure 12 , more than two human-powered power generation devices can be installed on a guide column 800, so as to meet the needs of exercising both arms at the same time, or for more than two users to use at the same time. Figure 13 As shown in the dotted and solid lines in FIG, when the positions of the two hands of the user pulling the pulling rope 520 change, the human-powered power generation device can move along with the position changes of the hands, so that the pulling rope 520 of the human-powered power generation device is perpendicular to the guide column 800, which is beneficial to improving the power generation efficiency.

[0125] The two ends of the guide column 800 can be provided with fixing seats 801 to connect with the fixed object. Figure 14The fixing base 801 may be L-shaped and include a first fixing plate 8011 fixedly connected to the guide column 800 and a second fixing plate 8012 fixedly connected to another object. The first fixing plate 8011 may be fixed to the end surface of the guide column 800 by screws parallel to the guide column 800, while the second fixing plate 8012 may be fixed to the corresponding fixed object by screws perpendicular to the guide column 800. In some other embodiments, for a table with a profile, the human-powered power generation device may be directly fixed to the profile provided on the table.

[0126] In order to fix the human power generation device on the guide column 800, in a specific embodiment, please refer to Figure 15 The device connection base 700 also includes a connecting ring 730. The sliding sleeve portion 710 and the connecting ring 730 can be fixedly connected by screws. The connecting ring 730 is provided with screw holes, which can be tightened and fixed between the rewind unit housing 140 and the pull rope unit housing 130 by screws. In some other embodiments, the sliding sleeve portion 710 can also be integrally connected to the device housing, or connected to the device housing via other fixing structures, such as being directly fixed to the outer circumference of the device housing via screws perpendicular to the axis of the rope pulley 510. Since the direction for pulling the pull rope 520 is backward, in order to balance the force, the device connection base can be fixed to the front side of the device housing.

[0127] A guide block 711 is fixed on the inner wall of the sliding sleeve part 710, and the guide block 711 has a sliding mating surface for fitting with the guide column 800, and the sliding mating surface is formed of a ceramic material. The base of the guide block 711 can be made of plastic material, and a ceramic layer is provided on the surface. This structure can refer to the existing structure in the relevant technology and will not be described here. The use of this structure can smoothly ensure the sliding of the sliding sleeve part 710, for example, it can move smoothly and freely along the guide column 800 following the pulling direction of the traction rope 520 by the user, ensuring that the user's pulling force is converted to drive the pulley 510 to a greater extent, which is beneficial to improve the power generation efficiency. There is no limit to the fixing method of the guide block 711 and the sliding sleeve part 710, such as bonding, fastener connection, snap connection, etc. In one embodiment, please refer to Figure 15 、 Figure 16 , a screw hole can be provided on the side wall of the sliding sleeve portion 710 , and a screw passes through the screw hole and is threadedly connected to the guide block 711 to fix the guide block 711 to the sliding sleeve portion 710 .

[0128] In some other embodiments, the guide block 711 may also be replaced with a plastic having a self-lubricating function, such as Teflon, nylon, etc. In addition, the guide block 711 and the sliding sleeve portion 710 may be an integral structure.

[0129] According to different user needs, in some embodiments, a locking mechanism can also be provided on the device connection base 700, and the locking mechanism is used to lock the device connection base 700 on the guide column 800. For example, if the user needs to exercise the arm muscles and shoulder muscles, he can refer to Figure 13 Facing or facing away from the human-powered power generation device, fix the two human-powered power generation devices on a fixed object and pull the pulling ropes 520 of the two human-powered power generation devices at the same time.

[0130] Please refer to Figures 16 to 18 The locking mechanism may include an operating handle 740, which is for the user to manually rotate to switch between the locked state and the unlocked state. The operating handle 740 is used for locking and unlocking operations without the need for other tools, and the operation is convenient. In a specific embodiment, the locking mechanism may include a locking nut 750 and a locking screw 760 fixedly connected to the operating handle 740. The head of the locking screw 760 can be embedded in the profile groove 802 on the corresponding side of the profile along the axial direction of the profile, and abut against the inner wall of the closing side of the profile groove 802 in a direction perpendicular to the corresponding side of the profile. In addition, the rod of the locking screw 760 has a square shaft portion 761, which can be adapted to the profile groove 802 to limit the rotation of the locking screw 760. The end of the locking screw 760's rod passes through the sidewall of the sleeve portion 710 and is threaded into a threaded hole provided on the locking nut 750. When the locking nut 750 is rotated by the operating handle 740, the device connector 700 can be conveniently abutted and locked to the guide post 800, or unlocked. In some other embodiments, the locking mechanism can also be replaced with other structural forms. For example, a stud is connected to the operating handle 740, and a threaded hole is provided on the sidewall of the sleeve portion 710. The operating handle 740 drives the stud to rotate, causing the stud to abut against the guide post 800, thereby achieving locking in the form of a set screw. For another example, the sleeve portion 710 can adopt a shrink sleeve to achieve locking by tightly hugging the guide post 800. In another example, pin holes arranged axially on the guide post 800 can be provided, and a positioning pin can be inserted into the sleeve portion 710 to achieve locking.

[0131] Please refer to Figure 18 The end of the locking nut 750 away from the locking screw 760 can be provided with a rotating shaft 751, which is assembled to the device connecting seat 700 through the bearing. To facilitate the installation of the bearing, please refer to Figure 15 A detachable movable stopper 712 can be provided on the device connecting seat 700. After the bearing is assembled on the rotating shaft 751 on the locking nut 750, it can be installed on the device connecting seat 700 in a direction perpendicular to the axial direction of the locking nut 750, and then rely on the movable stopper 712 to abut to achieve the positioning of the locking nut 750. The movable stopper 712 can be fixed to the device connecting seat 700 by screws.

[0132] The guide column 800 is more suitable for horizontal fixing. In order to adapt to different installation scenarios, such as installation on a flat desktop, in some embodiments, please refer to Figures 19 to 20 The device connection seat can be a ball head connection seat 900, which is fixed to the device housing. The ball head connection seat 900 can include a connecting ball head 910. The human-powered power generation device also includes a device mounting seat 920 for connecting to the device housing. The device mounting seat 920 includes an external structure for fixing to a corresponding object. The device mounting seat 920 is provided with a ball head mounting cavity 922, and the connecting ball head 910 is embedded in the ball head mounting cavity 922 to achieve yaw. The device mounting seat 920 has a length direction, and the external structure is provided at one end of the length direction of the device mounting seat 920. The external structure is used to fix the device mounting seat 920 in the vertical direction. By adopting the connecting ball head 910, the human-powered power generation device can adaptively adjust its own posture according to the pulling direction of the user, so as to ensure that the pulling direction is tangent to the pulley 510, thereby ensuring a higher power generation efficiency. In order to prevent the human-powered power generation device from swinging downward when idle, in a specific embodiment, a support member 930, such as a columnar support column, can be provided on the human-powered power generation device or the device mounting base 920, so that the human-powered power generation device can remain upright and more beautiful.

[0133] Among them, the external structure can use the card slot 941 and the push bolt 942 to connect the device mounting base 920 to the panel of the desktop, and then tighten the push bolt 942 to fix the device mounting base 920 to the desktop.

[0134] Please refer to Figure 19 The device mounting base 920 is provided with a ball head slot extending along its length.
