Description

Technical Field

[0001] This utility model relates to the field of human-powered power generation devices. Background Technology

[0002] Some human-powered power generation devices rely on pulling a pull rope to work. The pull rope is wound around a rope wheel. When the pull rope is pulled, it can drive the rope wheel to rotate, thereby driving the power generation unit to work and converting rotational kinetic energy into electrical energy.

[0003] To enhance user comfort, a handle can be installed at the end of the pull rope, allowing the user to grip it and distribute the force of the pull rope's reaction force on their hand. When the human-powered generator is used in fitness settings, for even greater comfort, the handle can be made rotatable. This requires a pivot point with a sleeve for the user to grip. This prevents hand discomfort caused by relative rotation when there is a tendency for the handle to rotate relative to the user's hand, such as when pulling the pull rope by swinging the arms from side to side.

[0004] However, since the handle is a pull ring structure, in order to rotatably fit the sleeve onto the pull ring, the pull ring needs to be set as a split structure that separates along the axial direction of the sleeve. This can easily affect the structural stability of the pull ring, and the handle is prone to damage during use, thus affecting the reliability of the product. Utility Model Content

[0005] This invention provides a human-powered power generation device and a handle structure that can avoid affecting the structural stability of the handle in order to achieve rotation.

[0012] In one embodiment, the sleeve further includes at least two bushing assemblies joined circumferentially along the sleeve, the bushing assemblies being supported between the handle frame and the support sleeve to allow the end face coupling member to be rotatably mounted on the handle frame.

[0013] In one embodiment, the bushing assembly is positioned circumferentially on the end face coupling member along the sleeve.

[0014] In one embodiment, the inner wall of the support sleeve is provided with a positioning groove or a positioning protrusion, and the bushing assembly is provided with an adapter protrusion for embedding in the positioning groove or an adapter groove for embedding the positioning protrusion, so that the bushing assembly is positioned on the end face coupling member along the circumference of the sleeve.

[0015] In one embodiment, the axial end of the sleeve support is provided with a limiting step, which allows the bushing assembly to be positioned along the axial direction of the sleeve.

[0016] In one embodiment, the seam of the bushing assembly is offset from the seam of the two adjacent end face coupling members along the circumference of the sleeve.

[0019] In one embodiment, the cylindrical assembly includes an assembly body and an inner flange disposed at the end of the assembly body. The handle structure further includes an axial fastener, which fixes the end face coupling member to the inner flange along the circumference of the sleeve.

[0020] In one embodiment, a cover layer is further included, which covers the entire circumference of the sleeve.

[0021] In one embodiment, the handle frame further includes a frame connecting portion connected between the sleeve mounting portion and the rope connecting portion, wherein the length of the sleeve mounting portion is greater than the length of the rope connecting portion, the sleeve mounting portion and the rope connecting portion are centrally aligned, and the handle frame is an isosceles trapezoidal structure.

[0022] In one embodiment, the handle frame is a closed-loop structure.

[0023] Secondly, this application provides a human-powered power generation device, comprising:

[0024] The generator main unit includes a pull rope unit, which includes a pull rope and a pull rope. The pull rope is wound around the pull rope and is used by a user to pull the pull rope to drive the pull rope to rotate.

[0028] The beneficial effects of this utility model are:

[0029] According to the handle structure in the embodiments of this utility model, each cylindrical assembly can be arranged around the sleeve mounting part of the handle frame and spliced ​​together along the circumference of the sleeve to form a sleeve. Thus, it is not necessary to set the handle frame as a split structure to fit the sleeve axially outside the handle frame. At the same time, the coupling member crosses the splicing part between two adjacent cylindrical assemblies. The coupling member is fixedly connected to the two corresponding cylindrical assemblies located on both sides of the splicing seam, which enables each cylindrical assembly to maintain the spliced ​​state and rotate relative to the sleeve mounting part, satisfying the rotation requirements of the sleeve. Since the sleeve located outside the sleeve mounting part has a larger size than the sleeve mounting part, although the sleeve mounting part adopts a split structure, it is easier to ensure the structural strength after circumferential splicing, which is beneficial to ensuring the structural stability of the handle.

[0069] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification.

[0071] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art.

[0073] In the embodiments of this utility model, the sleeve for the user to grip in the handle structure adopts a circumferential splicing structure. The sleeve can be installed radially to the sleeve mounting part on the handle frame. Compared with setting the handle frame as a split structure and assembling it with the sleeve along the sleeve axis, using the coupling member to keep the various cylinder assembly parts in a spliced ​​state is beneficial to ensuring the structural stability of the handle.

[0074] To more clearly illustrate the specific embodiments of this utility model, the following description uses the top and bottom orientations shown in the figures. Of course, this orientation limitation in the embodiments is merely an example to more clearly illustrate the positional relationships between the various components, and does not limit the embodiments of this utility model to this arrangement.

[0075] An embodiment of the human-powered power generation device of this utility model:

[0076] Please refer to Figures 1 to 4 In one embodiment, the human-powered power generation device includes a power generation unit 1000 and a pull handle 2000. During operation, the power generation unit 1000 is connected to a corresponding fixed object, and the user repeatedly pulls the pull handle 2000 to generate electricity.

[0077] In addition to generating electricity, the aforementioned human-powered power generation device can also be used as a resistance generator in a resistance training device to achieve resistance training. The resistance training device can provide resistance to the resistance rope 1220. Users need to pull the resistance rope 1220 with a certain amount of force to achieve the training purpose.

[0078] The specific structure of the human-powered power generation device will be described below.

[0079] Please refer to Figure 1 , Figure 5 and Figure 6In some embodiments, the generator main unit 1000 may include a device housing 1100, a rope pulling unit 1200, a speed changing unit 1300, a generator unit 1500, etc.

[0080] The rope-pulling unit 1200 includes a rope pulley 1210 and a pull rope 1220. The rope pulley 1210 is rotatably mounted on the device housing 1100. The pull rope 1220 is wound around the rope pulley 1210 to drive the rope pulley 1210 to rotate when pulled out. The pull rope 1220 has a fixed end that is fixedly connected to the rope pulley 1210 and a pull end for the user to pull.

[0081] In one embodiment, the rope pulley 1210 of the rope unit 1200 is rotatably mounted in the device housing 1100 via a first bearing 1231 and a second bearing 1232. The rope pulley 1210 is provided with a groove, which allows the pulling rope 1220 to be wound around and positions the pulling rope 1220 along the axial direction of the rope pulley 1210.

[0082] The pull rope 1220 can be a belt with a roughly rectangular cross-section. The width of the belt matches the width of the pulley groove, resulting in better tensile strength and stability. In some other embodiments, the pulley 1210 may omit the pulley groove, and the pull rope 1220 may also have other cross-sectional shapes, such as circular or square. The fixed end of the pull rope 1220 can be fixedly connected to the pulley 1210 in any way, such as by bonding, snapping, or fastening.

[0083] The speed change unit 1300 is used to achieve speed-increasing transmission from the pulley 1210 to the power generation unit 1500, which can increase the rotational speed of the power input component of the power generation unit 1500, enabling the power generation unit 1500 to operate in the high-efficiency power generation range and facilitating the achievement of greater power generation. The specific structural form of the speed change unit 1300 is not limited; for example, it can be a modular unit, or the device housing 1100 can be used as a mounting base to assemble different components, forming the speed change unit 1300. In one embodiment, the speed change unit 1300 can be a planetary reducer or a fixed-axis gear transmission.

[0084] Please refer to Figure 5 and Figure 6 In some embodiments, the pulley 1210 has a hollow structure, and at least a portion of the speed change unit 1300 is disposed in the internal cavity of the pulley 1210, which helps to save axial dimensions.

[0085] The transmission unit 1300 has a transmission input shaft 1310. A one-way transmission structure 1400 is provided between the transmission input shaft 1310 and the pulley 1210. The structure of the one-way transmission structure 1400 is not limited, and can be formed by one of the following: a one-way bearing, a one-way clutch, or a ratchet structure. The one-way clutch can be a friction one-way clutch, a roller one-way clutch, etc. The specific structure of the one-way transmission structure 1400 can refer to existing structures in related technologies. Considering that it is not directly related to the innovative content and technical problem to be solved in this application, it will not be described in detail here.

[0086] The power generation unit 1500 converts the rotational kinetic energy transmitted from the pulley 1210 into electrical energy, where rotational kinetic energy is the kinetic energy generated by the rotation of an object. The power generation unit 1500 is fixed within its housing and its specific type is not limited; for example, it can be an AC generator or a DC generator. In one specific embodiment, the power generation unit 1500 includes a power input component, which is drive-connected to the output component of the transmission unit 1300. The specific connection method can refer to existing structures in related technologies; however, considering that it is not directly related to the innovative content and technical problem to be solved in this application, it will not be described in detail here.

[0087] In order to transmit the electrical energy generated by the power generation unit 1500 to the outside, in one embodiment, please refer to Figure 2 , Figure 5 and Figure 6 A connector 1800 is provided on the bottom wall of the device housing 1100. The connector 1800 forms the power output terminal of the power generation unit 1500, and other electrical components can be connected to the connector 1800 to achieve power supply through the power generation unit 1500.

[0088] When the user pulls the pull rope 1220 out of the device housing 1100, the pull rope 1220 wound on the rope wheel 1210 can drive the rope wheel 1210 to rotate in the first direction of rotation, thereby driving the power generation unit 1500 to rotate. The power generation unit 1500 converts the rotational kinetic energy into electrical energy to realize human-powered power generation. After the pulling action is completed, the pull rope 1220 is unwound. In order to realize repeated pulling, the human-powered power generation device also includes a rewinding unit 1600. The rewinding unit 1600 is located on the top side of the rope wheel 1210 unit and is used to rewind the pull rope 1220 that has been pulled out of the device housing 1100 onto the rope wheel 1210 to prepare for the next pulling process. At the same time, the one-way transmission structure 1400 can disconnect the power transmission path between the rope wheel 1210 and the power generation unit 1500 to ensure the effective rewinding of the pull rope 1220.

[0089] The specific structure of the rewind unit 1600 will be described below.

[0090] The rewinding unit 1600 includes an elastic colloid 1610, a support roller group 1620, a fixed tension member 1631, and a movable tension member 1632.

[0091] The elastic colloid 1610 can elastically stretch and contract along its own length. The material of the elastic colloid 1610 can be selected according to performance requirements, such as rubber, silicone, etc. For example, the annular elastic colloid 1610 can be made of rubber band. To achieve high resilience and service life, industrial rubber bands can be used. For example, in some embodiments, the thickness of the elastic colloid 1610 is not less than 1 mm and the width is not less than 3 mm. In some other embodiments, the elastic colloid 1610 between the traction seat and the rope pulley 1210 can also be replaced with other structural forms. For example, the elastic colloid 1610 can be a rod-shaped structure with no limitation on its cross-sectional shape, such as a circular, elliptical, rectangular, or regular polygonal cross-section.

[0092] The support roller assembly 1620 includes support rollers 1621 distributed around the rotation axis of the rope sheave, which is the rotation axis of the rope sheave 1210. Each support roller 1621 has its own axis of rotation and an outer peripheral surface for supporting the elastic colloid 1610. The rotational assembly method of the support rollers 1621 is not limited; exemplarily, in one specific embodiment, please refer to... Figures 5 to 10 The support roller assembly 1620 is mounted on the rope pulley 1210. Please refer to [reference needed]. Figure 6 , Figure 9 The top of the pulley 1210 is provided with rollers 1622, and each roller 1622 is located on the same circumference. In some other embodiments, each roller 1622 may also be arranged in a polygonal, elliptical or other shapes.

[0093] The bottom end of the roller shaft 1622 is fixedly connected to the rope pulley 1210, and the top end of the roller shaft 1622 is connected to the same fixing ring 1623. The support roller 1621 has an assembly hole at its rotation axis. The support roller 1621 is fitted onto the roller shaft 1622 through the assembly hole and is axially positioned by the fixing ring 1623. In this way, the support roller 1621 can be rotatably mounted on the rope pulley 1210 along its respective rotation axis. The support roller 1621 can be a cylinder or other shapes, such as a cylinder that is thinner at both ends and thicker in the middle, or a cylinder that is thicker at both ends and thinner in the middle, or a cylinder with an annular groove on its surface.

[0094] The support roller 1621 can be made of a material with self-lubricating properties, such as PTFE (Polytetrafluoroethylene), which is more conducive to reducing the friction between it and the elastic colloid 1610 and facilitating the elastic stretching and deformation of the elastic colloid 1610.

[0095] In the illustrated embodiment, the support roller assembly 1620 is mounted on the rope wheel 1210. When the rope wheel 1210 rotates, it drives the support roller assembly 1620 to rotate. The support roller assembly 1620 can apply a certain rotational driving force to the elastic colloid 1610, thereby facilitating the uniform stretching of different parts of the elastic colloid 1610. In some other embodiments, the support roller assembly 1620 can also be mounted on other components besides the rope wheel 1210, such as the adjusting seat 1640 described below. When the manual power generation device does not have the adjusting seat 1640, the support roller assembly 1620 can also be mounted on the device housing 1100.

[0096] The fixed traction member 1631 is fixedly installed relative to the device housing 1100 when the manual power generation device is working. To achieve the rewinding of the traction rope 1220, a movable traction member 1632 is connected to the rope pulley 1210. The first end of the elastic gel 1610 is connected to the fixed traction member 1631, and the second end of the elastic gel 1610 is connected to the movable traction member 1632. The distance from the movable traction member 1632 to the rotation axis of the rope pulley is greater than the distance from the support roller 1621 to the rotation axis of the rope pulley. Thus, when the rope pulley 1210 rotates in the first direction of rotation, the movable traction member 1632 causes the elastic gel 1610 to wrap around the support roller assembly 1620, causing the elastic gel 1610 to stretch and accumulate elastic force. This elastic force is used to provide a driving force to the rope pulley 1210 to rotate in a second direction opposite to the first direction of rotation.

[0097] It should be noted that the elastic colloid 1610 can be wrapped around the support roller assembly 1620 in a layered or spiral manner. For example, the elastic colloid 1610 can be an elastic band, which can be wrapped around the support roller assembly 1620 in a layered manner when the movable pulling member 1632 rotates around the axis of rotation of the rope wheel. Alternatively, the elastic colloid 1610 can be an elastic rope, such as an elastic rope with a circular cross-section, which can be wrapped around the support roller assembly 1620 in a spiral manner when the movable pulling member 1632 rotates around the axis of rotation of the rope wheel. To ensure that the elastic colloid 1610 is wrapped around the support roller assembly 1620 in a uniform spiral manner, in one specific embodiment, the connection points between the elastic colloid 1610 and the fixed pulling member 1631 and the connection points between the elastic colloid 1610 and the movable pulling member 1632 can be spaced apart along the axial direction of the rope wheel 1210.

[0098] In one specific embodiment, the elastic colloid 1610 is a closed annular colloid, the fixed pulling member 1631 is a first column mounted on the adjusting seat 1640, and the movable pulling member 1632 is a second column mounted on the rope wheel 1210. The first column extends downwards, and the second column extends upwards. The first end of the elastic colloid 1610 is attached to the first column, and the second end of the elastic colloid 1610 is attached to the second column. The use of a closed annular colloid and the suspended column allows for the attachment of both ends of the elastic colloid 1610, facilitating its disassembly, assembly, and replacement. Furthermore, the closed annular shape of the elastic colloid 1610 is equivalent to using two elastic colloids 1610 simultaneously to generate elasticity, which helps ensure sufficient rewinding driving force.

[0099] To prevent the elastic colloid 1610 from detaching from the first and / or second pillars, an annular positioning groove or hook can be provided on the outer circumferential surface of the first and / or second pillars, and the end of the elastic colloid 1610 can be embedded in the annular positioning groove or hook. In some other embodiments, the two ends of the elastic colloid 1610 can be connected to the fixed tension member 1631 and the movable tension member 1632 in other ways, such as by fasteners such as screws or clamps. The fixed tension member 1631 and the movable tension member 1632 can also be provided with a clamping structure for clamping and fixing the elastic colloid 1610.

[0100] Depending on factors such as the length of the pull rope 1220 and the diameter of the pulley 1210, when the manual power generator is working, from the time the pull rope 1220 is fully retracted into the device housing 1100 to the time it is fully extended, the rotation angle of the pulley 1210 can be less than or equal to a complete circumference (360 degrees); the rotation angle of the pulley 1210 can also be greater than 360 degrees. Correspondingly, the number of rotations of the pulley 1210 can be less than or equal to one rotation, or greater than one rotation. When the number of rotations of the pulley 1210 is greater than one rotation, the fixed pulling member 1631 is positioned outside the area enclosed by the support rollers 1621, and the distance from the movable pulling member 1632 to the rotation axis of the pulley is greater than the distance from the fixed pulling member 1631 to the rotation axis of the pulley, so that the amount of wrapping of the fixed pulling member 1631 on the support roller assembly 1620 is greater than one rotation. It should be noted that when the support roller assembly 1620 is set on the adjusting seat 1640 or the device housing 1100, the support roller assembly 1620 is fixed relative to the device housing 1100 when the human power generation device is working. At this time, the fixed tensioning member 1631 can also be set inside the area enclosed by the support roller 1621.

[0101] To ensure that the pull rope 1220 can be fully retracted when not being pulled, and to facilitate adjustment of the force applied by the user when pulling the pull rope 1220, in some embodiments, the human-powered generator includes an adjusting seat 1640. A fixed pulling member 1631 is fixed to the adjusting seat 1640. The adjusting seat 1640 is mounted on the device housing 1100 and is adjustable in circumferential position along the rope pulley 1210. The adjusting seat 1640 is used to drive the fixed pulling member 1631 to move circumferentially along the rope pulley 1210 when adjusting the circumferential position, thereby changing the tension of the elastic colloid 1610. The adjusting seat 1640 has a tension adjustment direction for tensioning the elastic colloid 1610 (e.g., ...). Figure 11 (As indicated by the arrow in the image), the relaxation adjustment direction for relaxing the elastic colloid 1610.

[0102] In one specific embodiment, the adjusting seat 1640 includes an annular body 1641 and a support beam 1642. The support beam 1642 is disposed within the annular body 1641, and a fixing tension member 1631 is fixed to the support beam 1642. The annular body 1641 can form an observation channel for observing the elastic colloid 1610, facilitating the understanding of the usage of the elastic colloid 1610. Optionally, the support beam 1642 is detachably mounted on the annular body 1641 along the axial direction of the pulley 1210. This allows the elastic colloid 1610 to be easily replaced by removing the support beam 1642 and simultaneously removing the fixing tension member 1631.

[0103] The aforementioned adjusting seat 1640 forms an inner cavity at one axial end of the human-powered generator to accommodate the elastic colloid 1610. The inner cavity has an opening for the elastic colloid 1610 to be exposed. The human-powered generator also includes a protective net 1700, which is detachably sealed at the opening. The protective net 1700 prevents foreign objects from entering the interior of the human-powered generator and also improves heat dissipation. In some other embodiments, without the adjusting seat 1640, an opening can be provided at the top of the device housing 1100, and the protective net 1700 can be directly disposed at the top of the device housing 1100.

[0104] In some embodiments, two slots may be provided on the top surface of the annular body 1641, and both ends of the support beam 1642 are respectively embedded in the slots in the vertical direction, thereby enabling the support beam 1642 to be easily assembled and disassembled without the use of tools. In some other embodiments, the support beam 1642 may also be detachably assembled to the annular body 1641 in other ways, such as by fixing it to the support beam 1642 with screws. In some other embodiments, the support beam 1642 may also be a cantilever beam.

[0105] After the adjusting seat 1640 is adjusted to the correct position, it needs to be positioned relative to the device housing 1100. Those skilled in the art will understand that this positioning can be achieved in any way. For example, the adjusting seat 1640 can be directly fixed to the outer peripheral wall of the device housing 1100 using screws; alternatively, a set screw can be provided on the outer peripheral wall of the device housing 1100, and the adjusted seat 1640 can be tightened by the set screw. Besides the above-mentioned fastening method, in some other embodiments, positioning can also be achieved in other ways. For example, positioning grooves distributed circumferentially can be provided on the device housing 1100, and positioning protrusions can be provided on the adjusting seat 1640. Positioning of the adjusting seat 1640 can be achieved by having the positioning protrusions embed into different positioning grooves.

[0106] In one specific embodiment, please refer to Figures 5 to 7 The device housing 1100 has a mounting cavity located on one axial side of the pulley 1210, and at least a portion of the adjusting seat 1640 is embedded in the mounting cavity; the human-powered generator also includes first teeth 1651 distributed circumferentially within the mounting cavity along the pulley 1210 (see...). Figure 11 The second tooth 1661 (see) is distributed circumferentially along the pulley 1210 on the side of the adjusting seat 1640 near the pulley 1210. Figure 11 The first tooth 1651 has a limiting surface 1652 on one side corresponding to the tension adjustment direction. The limiting surface 1652 is used to abut against the limiting adapter surface 1662 on the second tooth 1661 to restrict the adjustment seat 1640 from rotating in the relaxation adjustment direction.

[0107] Please refer to Figure 11 In one specific embodiment, the human-powered generator includes an adjusting and positioning component, which comprises a first positioning ring 1650 and a second positioning ring 1660. The first positioning ring 1650 is circumferentially positioned on the device housing 1100 along the rope pulley 1210, and a first tooth 1651 is disposed on the first positioning ring 1650. The second positioning ring 1660 is circumferentially positioned on an adjusting seat 1640 along the rope pulley 1210, and a second tooth 1661 is disposed on the second positioning ring 1660. The circumferential positioning of the first positioning ring 1650 and the second positioning ring 1660 can be achieved in any form. Taking the second positioning ring 1660 as an example, a positioning protrusion can be provided on the top of the second positioning ring 1660, and a positioning cavity for the positioning protrusion to be inserted can be provided on the adjusting seat 1640.

[0108] It should be noted that the first positioning ring 1650 can also be fixed to the device housing 1100 or be integrally formed with the device housing 1100, and the second positioning ring 1660 can also be fixed to the adjusting seat 1640 or be integrally formed with the adjusting seat 1640; in some embodiments, please refer to Figure 12The first positioning ring 1650 can be provided with a first countersunk hole 1655, and the second positioning ring 1660 can be provided with a second countersunk hole 1665. The first positioning ring 1650 can be fixed to the device housing 1100 by a screw passing through the first countersunk hole 1655, and the second positioning ring 1660 can be fixed to the adjusting seat 1640 by a screw passing through the second countersunk hole 1665. The head of the screw can be recessed into the corresponding countersunk hole to avoid affecting the fit between the first positioning ring 1650 and the second positioning ring 1660. The first positioning ring 1650 and the second positioning ring 1660 can be complete rings, or they can be spliced ​​together along the circumference of the wheel axle, which is convenient for processing.

[0109] Those skilled in the art will understand that, in order to position the adjusting seat 1640 by means of the limiting surface 1652 of the first tooth 1651 and the limiting mating surface 1662 of the second tooth 1661, the limiting surface 1652 should have a certain angle, for example, parallel to the axis of the rope pulley 1210, or, please refer to Figure 12 The top of the limiting surface 1652 faces the tension adjustment direction relative to the bottom (e.g., Figure 12 As indicated by the arrow in the diagram, the first tooth 1651 is tilted, thus forming a wedge-shaped space. This wedge-shaped space allows the wedge-shaped teeth formed by the second tooth 1661 to engage. This not only positions the adjusting seat 1640 circumferentially along the rope wheel but also helps prevent the adjusting seat 1640 from detaching from the device housing 1100 axially along the rope wheel, ensuring stable positioning of the adjusting seat 1640. A slight tilt at the top of the limiting surface 1652 relative to its bottom towards the direction of relaxation also achieves a limiting function.

[0110] To facilitate adjustment of the position of the adjusting seat 1640, and consequently the position of the fixing tensioning member 1631, in some embodiments, the first tooth 1651 has a ramp surface 1653 on the side corresponding to the relaxation adjustment direction, and the second tooth 1661 has a ramp fitting surface 1663 that matches the ramp surface 1653. When the adjusting seat 1640 rotates in the tension adjustment direction, the adjusting seat 1640 moves in the direction of disengagement from the mounting cavity under the interaction of the ramp surface 1653 and the ramp fitting surface 1663. In this way, the user only needs to rotate the adjusting seat 1640 in the tension adjustment direction to rotate the second tooth 1661 on the adjusting seat 1640 to the next first tooth 1651 on the device housing 1100, making operation more convenient.

[0111] To prevent the adjusting seat 1640 from detaching from the device housing 1100, in some embodiments, one of the limiting surface 1652 and the limiting adapter surface 1662 is provided with a positioning protrusion 1654, and the other is provided with a positioning recess 1664. The positioning protrusion 1654 is used to be inserted into the positioning recess 1664 circumferentially along the pulley 1210 to limit the movement of the adjusting seat 1640 away from the first tooth 1651. Please refer to... Figure 11 The positioning protrusion 1654 can be a spherical structure, which facilitates entry into the positioning recess 1664 under the guidance of the spherical surface, thus improving the reliability of operation.

[0112] In some embodiments, the human-powered generator may further include an axial elastic band 1671, which also prevents the adjusting seat 1640 from detaching from the device housing 1100. The axial elastic band 1671 is elastically stretched between the adjusting seat 1640 and the rope wheel 1210 along the axis of rotation of the rope wheel. The axial elastic band 1671 can twist when the rope wheel 1210 rotates relative to the adjusting seat 1640. The axial elastic band 1671 can both apply a pulling force to the adjusting seat 1640 to prevent the adjusting seat 1640 from moving axially away from the device housing 1100 along the rope wheel 1210 and drive the pull rope 1220 to rewind by the elastic force generated by its own torsional deformation.

[0113] In one specific embodiment, please refer to Figures 7 to 9 The axial elastic belt 1671 is an annular closed belt. A first crossbeam 1672 is provided on the pulley 1210, and the first end of the annular closed belt is hooked onto the first crossbeam 1672. A second crossbeam 1673 is provided on the adjusting seat 1640, and the second end of the annular closed belt is hooked onto the second crossbeam 1673. The use of an annular closed belt facilitates the connection of the axial elastic belt 1671.

[0114] Please refer to Figure 9 The first crossbeam 1672 can be configured as follows: a crossbeam support 1674 protrudes from the end face of the rope pulley 1210 near the adjusting seat 1640, and the crossbeam support 1674 has a crossbeam through hole perpendicular to the rotation axis of the rope pulley. The end of the first crossbeam 1672 is fixed in the crossbeam through hole; each support roller 1621 is located on the same distribution circle, and the side of the crossbeam support 1674 away from the rotation axis of the rope pulley does not extend beyond the distribution circle. To fix the end of the first crossbeam 1672 in the crossbeam through hole, for example, a screw hole can be provided on the hole wall of the crossbeam through hole, and a set screw can be inserted to fix the first crossbeam 1672. In some other embodiments, an external thread can be provided on the outer circumferential surface of the first crossbeam 1672 and threadedly connected to the crossbeam through hole.

[0115] Please refer to Figure 7 , Figure 10The second crossbeam 1673 can be configured as follows: the second crossbeam 1673 can be shared with the support beam 1642 on the adjusting seat 1640. In order to facilitate the positioning of the axial elastic band 1671, the support beam 1642 can be provided with a positioning groove for the end of the axial elastic band 1671 to be positioned.

[0116] Please refer to Figure 6 In some embodiments, the human-powered generator may further include a damping element 1680, which also prevents the adjusting seat 1640 from detaching from the device housing 1100. The damping element 1680 may be disposed between the outer peripheral surface of the adjusting seat 1640 and the cavity wall of the mounting cavity to provide resistance to the movement of the adjusting seat 1640 relative to the device housing 1100. In one specific embodiment, the damping element 1680 is at least one elastic rubber ring, which is sleeved on the outer peripheral surface of the adjusting seat 1640.

[0117] The rewinding unit 1600, which includes the aforementioned elastic colloid 1610 and support roller assembly 1620, facilitates low-noise operation of the manual power generation device. In contrast, coil springs are prone to friction and noise during winding; furthermore, coil springs have a limited lifespan, and their rewinding force tends to weaken significantly after a certain working time. The elastic colloid 1610 and support roller assembly 1620 help maintain a stable rewinding force for a longer period. When the elastic colloid 1610 needs replacement, it can be easily removed by detaching the protective net 1700 and support beam 1642, or simply by removing the protective net 1700. Alternatively, the adjusting seat 1640 can also be removed for disassembly and assembly.

[0118] In some other embodiments, the rewind unit 1600 may also be in other structural forms, such as a coil spring.

[0119] The following will be combined with the appendix Figures 13 to 15 The handle structure of the pull handle 2000 is described in detail. The handle structure includes a sleeve 2100, a handle frame 2200, and a coupling element (e.g., an end-face coupling element 2300). The sleeve 2100 is for the user to grip and is rotatably mounted on the handle frame 2200. This prevents hand discomfort caused by the handle rotating relative to the hand when there is a relative rotational tendency between the handle and the user's palm, such as when a person pulls the pull rope 1220 by swinging their arm from side to side. In some embodiments, please refer to... Figures 13 to 15The sleeve 2100 includes two cylindrical assembly portions 2110 joined together circumferentially along the sleeve 2100. The sleeve 2100 is formed by joining the cylindrical assembly portions 2110. Those skilled in the art will understand that in some other embodiments, the number of cylindrical assembly portions 2110 may be three or more. In this case, the shape and size of each cylindrical assembly portion 2110 may be the same or different, as long as they can be joined together circumferentially along the sleeve 2100 to form a complete cylindrical body.

[0120] The handle frame 2200 has a first side and a second side. The handle frame 2200 includes a sleeve mounting portion 2210 located on the first side and a rope connecting portion 2220 located on the second side. Each cylinder assembly portion 2110 is arranged around the sleeve mounting portion 2210 and is rotatable around it. The rope connecting portion 2220 is used to connect to the object being pulled. It should be noted that the sleeve 2100 can be directly rotatably mounted on the sleeve mounting portion 2210, or rotatably mounted on the sleeve mounting portion 2210 via a rotating fitting. For example, the inner diameter of the sleeve 2100 can be configured to be larger than the outer diameter of the sleeve mounting portion 2210, thereby allowing direct rotatable mounting on the sleeve mounting portion 2210; or, as described below, the sleeve 2100 can be rotatably mounted on the sleeve mounting portion 2210 via the end face coupling member 2300 and the bushing assembly 2400.

[0121] The sleeve mounting portion 2210 and the rope connecting portion 2220 are integrated into a single structure, which helps ensure the overall structural strength and reliability of the handle frame 2200. In some other embodiments, the handle frame 2200 also includes a frame connecting portion 2230 connecting the sleeve mounting portion 2210 and the rope connecting portion 2220. The length of the sleeve mounting portion 2210 is greater than the length of the rope connecting portion 2220, and the sleeve mounting portion 2210 and the rope connecting portion 2220 are centrally aligned. The handle frame 2200 has an isosceles trapezoidal structure, which helps to ensure that the operator's pulling force is consistent with the length direction of the pull rope 1220, allowing the user's pulling force to act more effectively on the pull rope 1220 and preventing the handle 2000 from tilting relative to a plane perpendicular to the length direction of the pull rope 1220. In some other embodiments, the handle frame 2200 can also be other shapes, such as semicircular, triangular, etc.

[0122] In some embodiments, the handle frame 2200 is a closed-loop structure without any intermediate breaks, resulting in high structural integrity and better structural strength. The handle frame 2200 can be formed by welding the ends of bent wire, or it can be integrally formed by casting, forging, powder metallurgy, or other methods.

[0123] When the handle frame 2200 adopts a closed-loop structure, in order to facilitate the connection between the pull handle 2000 and the pull rope 1220, in some embodiments, please refer to... Figure 14The pull rope 1220 includes a main body 1221 and a folded portion 1222. The transition portion between the main body 1221 and the folded portion 1222 wraps around the rope connection portion 2220. The handle structure also includes a rope buckle 1240, which has a rope passage. The main body 1221 and the folded portion 1222 have overlapping portions that pass through the rope passage simultaneously. A corresponding fastener 1241 passes through the rope buckle 1240 and the overlapping portions, thereby fixing the main body 1221 and the folded portion 1222 to the rope buckle 1240. The fastener 1241 can be a screw, rivet, or the like that that passes through the rope buckle 1240 and the overlapping portions. For example, in one specific embodiment, along the overlapping direction of the main body 1221 and the folded portion 1222, a threaded hole is provided on one side wall of the rope passage, and a screw hole is provided on the other side wall. The fastener 1241 can be a screw, which passes through the screw hole and is threaded into the threaded hole. Those skilled in the art will understand that in some other embodiments, the connection between the rope connector 2220 and the pull rope 1220 can also be replaced with any other form, as long as it can satisfy the pulling of the pull handle 2000 to the pull rope 1220.

[0124] The coupling element spans the splicing portion between two adjacent cylindrical assembly parts 2110, and is simultaneously fixedly connected to the two corresponding cylindrical assembly parts 2110 located on both sides of the splicing portion, so that each cylindrical assembly part 2110 remains in a spliced ​​state. Those skilled in the art will understand that the coupling element can be connected to the outer circumferential surface of the cylindrical assembly part 2110, the end face of the cylindrical assembly part 2110, or the inner circumferential surface of the cylindrical assembly part 2110.

[0125] By designing the sleeve 2100 as a separate structure and the handle frame 2200 as a single piece, the sleeve 2100 can be rotatably assembled onto the sleeve mounting portion 2210 of the handle frame 2200 in a circumferential splicing manner. A stable sleeve shape is maintained through a coupling component, meeting the user's gripping needs. Simultaneously, the sleeve 2100 located outside the sleeve mounting portion 2210 has a larger size than the sleeve mounting portion 2210. Compared to designing the handle frame 2200 as a separate structure, this makes it easier to ensure the structural strength of the spliced ​​parts, thus contributing to the structural stability of the handle.

[0126] At least a portion of the coupling element can be an end-face coupling element 2300, which is located at the axial end of the sleeve 2100 and fixedly connected to the end face of the sleeve 2100. Using an end-face coupling element 2300 helps ensure the flatness of the outer circumferential surface of the sleeve 2100. In one specific embodiment, please refer to... Figures 13 to 15The coupling element consists of two end-face coupling elements 2300. Each end-face coupling element 2300 includes a plate portion 2310 and a sleeve support portion 2320. The sleeve support portion 2320 protrudes from the plate portion 2310 near the sleeve 2100 and is arc-shaped. The sleeve support portions 2320 are assembled to form a support sleeve. The cylinder assembly portion 2110 is radially supported on the outer circumferential surface of the support sleeve along the sleeve 2100 to achieve radial positioning. The support sleeve formed by the sleeve support portions 2320 of the end-face coupling element 2300 provides support for the sleeve 2100, which helps improve the structural stability between the sleeve 2100 and the end-face coupling element 2300. In some other embodiments, the end-face coupling element 2300 may only be connected to the end face of the cylinder assembly portion 2110.

[0127] In one specific embodiment, the cylinder assembly 2110 includes an assembly body 2111 and an inner flange 2112 disposed at the end of the assembly body 2111. The handle structure also includes an axial fastener 2340, which fixes the end face coupling member 2300 to the inner flange 2112 along the circumference of the sleeve 2100. Figure 13 In the middle, because the cross-section passes through the circumferential splicing gap of the cylinder assembly 2110 and the circumferential splicing gap of the bushing assembly 2400, the cylinder assembly 2110 and the bushing assembly 2400 are not shown as cross-sectional lines.

[0128] The aforementioned axial fastener 2340 can be, for example, a screw, rivet, or other structure. The inner flange 2112 on the cylindrical assembly 2110 facilitates the formation of a larger end face area, which is beneficial for connecting the axial fastener 2340. In some other embodiments, other fixing methods can be used between the cylindrical assembly 2110 and the coupling member, such as bonding or welding. Those skilled in the art will understand that the inner flange 2112 on the cylindrical assembly 2110 can also be omitted; for example, the sleeve 2100 can have a thicker wall, in which case the axial fastener 2340 can be directly connected to the end face of the sleeve 2100's wall.

[0129] To ensure smooth rotation of the sleeve 2100, in some embodiments, the handle structure further includes at least two bushing assemblies 2400 spliced ​​circumferentially along the sleeve 2100. The bushing assemblies 2400 are supported between the handle frame 2200 and the support sleeve, so that the end face coupling member 2300 can be rotatably assembled onto the handle frame 2200. The bushing assemblies 2400 can be spliced ​​circumferentially along the sleeve 2100 to form a sleeve structure. The bushing material can be copper, ceramic, PEEK (Polyetheretherketone), nylon, etc. Preferably, a material with self-lubricating properties, such as PTFE (Polytetrafluoroethylene), can be used.

[0130] In some embodiments, the bushing assembly 2400 can be positioned circumferentially on the end face coupling member 2300 along the sleeve 2100. This ensures that the sleeve 2100, the end face coupling member 2300, and the bushing assembly 2400 are relatively fixed and integrally rotatably assembled on the sleeve mounting portion 2210, which helps guarantee the positional stability of the bushing assembly 2400 within the handle. In one specific embodiment, the inner wall of the support sleeve is provided with a positioning groove or a positioning protrusion, and the bushing assembly 2400 is provided with an adapter protrusion for embedding in the positioning groove or an adapter groove 2410 for embedding the positioning protrusion, so that the bushing assembly 2400 is positioned circumferentially on the end face coupling member 2300 along the sleeve 2100. In some other embodiments, the bushing assembly 2400 can also be positioned circumferentially on the end face coupling member 2300 by other means, such as bonding.

[0131] To ensure stable assembly of the bushing assembly 2400 between the handle frame 2200 and the support sleeve, in some embodiments, a limiting step 2330 is provided at the axial end of the sleeve support portion 2320. The limiting step 2330 provides axial positioning for the bushing assembly 2400 along the sleeve 2100. Of course, the limiting step 2330 can also be omitted, especially when the bushing assembly 2400 is bonded to the end face coupling member 2300, or when the axial dimension of the bushing assembly 2400 matches the axial spacing between the upper and lower end face coupling members 2300.

[0132] In some embodiments, axial limiting structures 2240 can be provided on the sleeve mounting portion 2210 at both axial ends of the sleeve 2100. The end face coupling member 2300 and the sleeve 2100 are positioned between the two axial limiting structures 2240 along the axial direction of the sleeve 2100. Providing the axial limiting structures 2240 can prevent the sleeve 2100 from moving axially on the handle frame 2200, which is beneficial for the user to accurately operate the pull handle 2000. The axial limiting structures 2240 can adopt different structural forms, for example... Figure 13 As shown, a collar is provided on the sleeve mounting portion 2210, and the axial limiting structure 2240 is formed by the collar. Using a collar as the axial limiting structure 2240 results in a relatively simple structure. In some other embodiments, the axial limiting structure 2240 can also take other forms. For example, an annular groove with an outer diameter smaller than that of the adjacent portion can be provided on the sleeve mounting portion 2210, and a shoulder can be formed on the sleeve mounting portion 2210, relying on the shoulder as the axial limiting structure 2240; or, for example, a snap ring, locating pin, etc. can be assembled on the sleeve mounting portion 2210 as the axial limiting structure 2240.

[0133] In some embodiments, the splice seam of the bushing assembly 2400 and the splice seam of the adjacent end face coupling members 2300 are staggered along the circumference of the sleeve 2100, so that each bushing assembly 2400 and each end face coupling member 2300 can mutually enhance the splice stability of the other.

[0134] The sleeve 2100 can be installed separately using the coupling member and the cylindrical assembly 2110 spliced ​​along the circumference of the sleeve 2100. However, this structure can also easily form seams on the surface of the sleeve 2100. In some embodiments, the handle structure further includes a cover layer 2500 that covers the entire circumference of the sleeve 2100, thereby avoiding the impact of seams on the feel. The cover layer 2500 can be an elastic cushioning layer that covers the outer circumferential surface of the sleeve 2100, which helps to improve grip comfort. The forming method of the cover layer 2500 is not limited. For example, it can be formed by winding a sheet onto the sleeve 2100, the sheet can be bonded to the outer circumferential surface of the sleeve 2100, it can be formed by dip molding, or it can be formed by insert injection molding / overmolding. When the handle frame 2200 does not have a closed-loop structure, the cover layer 2500 can also be an elastic cylinder. The elastic cylinder can be fitted onto the handle frame 2200 through the broken part of the handle frame 2200, and then fitted onto the sleeve 2100.

[0135] During assembly, the bushing assembly 2400, the end face coupling member 2300, and the cylinder assembly 2110 can be installed radially along the sleeve mounting portion 2210 in sequence. Then, the end face coupling member 2300 and the cylinder assembly 2110 are fixed together by the axial fastener 2340. When the above-mentioned pull handle 2000 is pulled, the sleeve 2100 can rotate on the sleeve mounting portion 2210, which helps to improve the user's operating comfort; and the end face coupling member 2300 and the cylinder assembly 2110 of the sleeve 2100 can easily form a more stable connection, which helps to ensure the structural stability of the handle.

[0136] After the power generator is used, to prevent the handle 2000 from drooping and pulling on the elastic band, and to avoid inconvenience in storage, in some embodiments, a handle positioning part 1110 is provided on the outer peripheral surface of the generator main unit 1000. The rope connection part 2220 of the handle positioning part 1110 is embedded on the side near the generator main unit 1000. The handle positioning part 1110 and / or the handle frame 2200 are magnetic, so as to magnetically fix the handle to the handle positioning part 1110. The magnetic nature of the handle positioning part 1110 and / or the handle frame 2200 means that the handle positioning part 1110 and / or the handle frame 2200 can generate a magnetic field themselves, or that they are provided with magnetic components that can generate a magnetic field. For example, please refer to Figure 2 , Figure 2This is also a schematic diagram of the handle storage structure. In some embodiments, the outer peripheral surface of the device housing 1100 is provided with an arc-shaped groove, and an arc-shaped magnetic sheet 1111 is fixed in the arc-shaped groove. The magnetic sheet 1111 can form a magnetic field to attract and pull the handle 2000. The handle 2000 can be attracted and fixed at the arc-shaped groove to achieve storage.
