Description

Novel self-generating wheel structure of axle wheel without differential synchronous rotation TECHNICAL FIELD

[0001] The utility model relates to generating wheel technical field especially novel self-generating wheel structure of axle wheel without differential synchronous rotation. BACKGROUND

[0002] The current power generation device refers to the mechanical equipment that other forms of energy are converted into electric energy, it is driven by water turbine, steam turbine, diesel engine or other power machinery, and the energy that water flow, air flow, fuel combustion or atomic nucleus fission generates is converted into mechanical energy and is given to the generator core, and then the generator core is converted into electric energy. The generator core has a wide range of uses in industrial and agricultural production, national defense, science and technology and daily life.

[0003] There are many kinds of power generation devices, and rotating generator core is one of the common ones. The existing rotating generator core is composed of multiple coils and multiple pole magnetic rings. At present, the rotating generator core is applied to the rotating wheels of scooters, skating shoes, trolleys, bicycles and the like, so that the rotating wheels generate electricity during walking and power the connected components to realize light emission or other entertainment effects.

[0004] There are many patent literatures about light-emitting wheels, such as the authorized announcement No. 218839052 U discloses a blow molding light-emitting wheel, wherein the light-emitting assembly includes a coil winding and a circuit board, and the coil winding, the circuit board and the lamp beads are electrically connected. It further includes a magnetic core, which is rotationally assembled with the light-emitting assembly. The magnetic field formed by the magnetic core is outward, so when the coil winding rotates (i.e. when the wheel body moves), the coil winding cuts the magnetic field formed by the magnetic core to generate current. During installation, the external tool connecting rod is inserted into the second bearing, the magnetic core (the middle part of the magnetic core forms a hollow mounting channel), and the first bearing in sequence, and then the screw cap or nut is screwed into the end of the external tool connecting rod (the end of the external tool connecting rod forms an external thread matched with the screw cap or nut) to lock, so as to rotationally connect the wheel body on the external tool connecting rod. Finally, the light-emitting wheel is connected to the external vehicle body through the external tool connecting rod.

Best mode of the present application

[0046] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to explain and illustrate the present application, and are not used to limit the present application.

[0047] The utility model discloses a novel self-generating wheel body structure of axle wheel no differential synchronous rotation as shown in figures 1-6, the purpose is to make the rotation of the middle rotating shaft rod 302 can drive the rotation of the wheel 1, and the angular velocity of both rotation is same, the wheel 1 can generate electricity in the walking process, the self-generating wheel body structure can be applied to the wheel body at the front fork of the tricycle as the representative, therefore the wheel body is driven to rotate by the pedal rotation, and there is no generating electricity wheel in the aspect at present.

[0048] Specifically, the self-generating wheel body structure includes a fixed component and a rotatable component coupled, the rotatable component includes a wheel 1, the wheel 1 includes a hub 101 and a tire 102 wrapped outside the hub 101, a connecting member 2 is arranged in the rotatable component, the connecting member 2 is connected at the center part of the hub 101, the connecting member 2 is provided with a mounting position 201 for installing a power component 3, the power component 3 is connected at the mounting position and fixed with the connecting member 2, that is, the power component 3 drives the rotation of the connecting member 2, the power component 3 is driven by a power source to generate torque, and then drives the rotatable component to rotate around an axis relative to the fixed component.

[0049] The central axis of the wheel 1 and the connecting member 2 coincides with the rotation center line of the power component 3, that is, the connecting member 2 is located at the central part of the wheel 1 and coincides with the center line of both, so that the rotation force generated by the connecting member 2 when rotating under force can be evenly transmitted to the periphery of the wheel 1 to drive the wheel 1 to rotate together, as known from the following, the power component 3 is driven by the foot, therefore, the central axis of the wheel 1 and the connecting member 2 coincides with the rotation center line of the power component 3, not only helps the rotation force of the power component 3 to transmit to the connecting member 2 and the wheel 1, but also makes the user (child) to step more smoothly, and there is no phenomenon that the resistance (child's stepping force) changes due to the change of the resistance arm when the wheel 1 walks, or the phenomenon that the wheel 1 bounces when walking due to eccentricity. The rotation surface of the wheel 1 and the connecting member 2 is perpendicular to the rotation center line of the power component 3, therefore the wheel 1 is vertically arranged when fixed on the child's car, therefore the above-mentioned setting is beneficial to the wheel 1 to walk forward and backward when the power component 3 rotates.

[0050] The combination of the fixed part and the rotatable part is provided with a corresponding magnetic ring 4 and a generator core 5; the rotatable part rotates relative to the fixed part, so that the generator core 5 and the magnetic ring 4 rotate relative to each other to cut the magnetic force lines to generate current. According to the prior art, the generator core 5 includes a coil group, a circuit board and other components, and the relative rotation between the magnetic ring 4 and the coil group in the generator core 5 cuts the magnetic force lines to generate current, which is the prior art and will not be described here.

[0051] The self-generating wheel body is a specific structure of the generating wheel:

[0052] As shown in FIGS. 1-6, the self-generating wheel body is a specific introduction of the generating wheel. The generator core 5 is fixedly installed on the fixed part, and the magnetic ring 4 is fixedly installed on the connecting member 2. Specifically, the fixed part includes a front fork 6, which is part of a child's car. The lower end of the front fork 6 is connected to an end cover 7, and the end cover 7 is provided with an inlay position 701. The corresponding side of the generator core 5 is provided with a boss 501, which is fitted into the inlay position 701, so that the generator core 5 is inlaid and fixed on the end cover 7. In this generating wheel, the current generated by the generator core 5 is output to the electrical components (such as light emitting lamps, horns or other low-power electrical instruments) on the child's car for use. Therefore, the structure also includes an outgoing wire 12, the inner end of which is connected to the generator core 5, and the outer end of which is connected to the end cover 7 and the internal space of the front fork 6. Therefore, the generator core 5 is in a fixed state, avoiding the phenomenon of winding the outgoing wire 12 caused by the rotation of the generator core 5.

[0053] The hub 101 is connected to a protective cover 8, and the middle part of the protective cover 8 is formed with a convex ring 801. The magnetic ring 4 is inlaid in the convex ring 801 and is used in position corresponding to the generator core 5. That is, during the running of the wheel 1, the magnetic ring 4 is driven to rotate relative to the generator core 5 to generate electricity. The protective cover 8 prevents foreign objects from entering the hub 101 and causing damage.

[0054] The self-generating wheel body is a specific structure of the first embodiment of the light-emitting wheel:

[0055] Figures 9 to 16 illustrate a specific embodiment of the self-generating wheel that is a light-emitting wheel. The generator core 5 is connected to the wheel hub 101, and the magnetic ring 4 is fixedly mounted on a fixed component. The fixed component includes a front fork 6, which is part of the children's bicycle. A boss 601 is provided on the inner side of the lower end of the front fork 6, extending towards the center of the wheel hub 101. The magnetic ring 4 is connected to the boss 601. The generator core 5 is located in the middle of the wheel hub 101, corresponding to and matching the position of the magnetic ring 4. Several light-emitting lamps 11 are connected to the generator core 5, and the current generated by the generator core 5 is directly supplied to the light-emitting lamps 11 fixedly connected to it. Therefore, in this embodiment, there is no need to consider the issue of leading wires outward from the generator core 5; thus, the generator core 5 rotates with the wheel body 1, while the magnetic ring 4 remains stationary.

[0056] In the aforementioned power generation wheel and light-emitting wheel, bearings 9 are provided on both sides of the connecting member 2; the inner ring of the bearing 9 is fixedly connected to the connecting member 2, and the outer ring of the bearing 9 is fixed to the front fork 6 fixed to the fixed component or the end cap 7 connected to the front fork 6, so that the connecting member 2 can be rotatably assembled in the front fork 6.

[0057] The self-generating wheel body is a specific structure of the second embodiment of the light-emitting wheel:

[0058] Figures 17 to 21 illustrate a specific embodiment of the self-generating wheel that is a light-emitting wheel. The generator core 5 is connected to the hub 101, and the magnetic ring 4 is fixedly mounted on a fixed component. The fixed component includes a fork 6, and a connector 10 is provided at the lower end of the fork 6. The inner side of the connector 10 extends towards the center of the hub 101, and the magnetic ring 4 is connected to the connector 10. The power component 3 is rotatably disposed in the connector 10. A major difference between this embodiment and the first embodiment is that, as shown in Figure 18, a channel is provided in the middle of the connector 10, and the rotation of the power component 3 is disposed in the channel without bearings. The generator core 5 is disposed in the middle of the hub 101 and is matched with the position of the magnetic ring 4.

[0059] However, in both the first and second embodiments, the generator core 5 and the hub 101 can be integrally formed, or the generator core 5 can be detachably fixed in the hub 101. That is, the generator core 5 is fixed in the integrally formed hub 101. When manufacturing the hub 101, the generator core 5 is placed into the mold and integrally injection molded to form the hub 101. In this case, the generator core 5 is wrapped in the hub 101. This structure will make the generator core 5 more stable in the hub 101 and less prone to loosening. Alternatively, the side of the hub 101 is formed with a mounting port 1011 for assembling the generator core 5. The circumferential groove 10111 is provided, and the axial protrusion 502 is provided on the generator core 5. When the generator core 5 is assembled into the mounting port 1011, the protrusion 502 is inserted into the groove 10111 for limiting the relative rotation between the generator core 5 and the hub 101. This structure involves manufacturing the hub 101 and then placing the generator core 5 into it for installation. Although this structure is not as stable as the one-piece molding structure above, the generator core 5 will not be easily damaged by being immersed in the high-temperature raw materials during the injection molding of the hub 101. Therefore, each has its advantages and disadvantages, and the choice can be made according to the actual process and cost.

[0060] As shown in Figure 13, several light-emitting lamps 11 are equidistantly distributed on the outer periphery of the generator core 5. The included angle θ1 between adjacent light-emitting lamps 11 is set to a range of 55~65°. The above-mentioned angle setting allows the number of light-emitting lamps 11 to be kept at around 5~7. Therefore, the inventor has found that this number is sufficient to ensure that the light-emitting lamps 11 light up and form a halo shape when the wheel 1 rotates at a low speed. The desired effect will not be failed due to a small number of light-emitting lamps 11, nor will the manufacturing cost be increased due to a large number of light-emitting lamps 11, thus reducing the marginal effect.

[0061] The light-emitting lamp 11 can be positioned towards the outer periphery of the wheel 1 as shown in Figure 13, so that the light shines on the groove of the wheel hub 101 and then is emitted through the protective cover 8. In this structure where the self-generating wheel is a light-emitting wheel, the protective cover 8 is made of a light-transmitting material, which not only protects the interior but also facilitates the emission of light. Alternatively, the light-emitting lamp 11 can be positioned on one side of the protective cover 8, perpendicular to the plane of rotation of the wheel 1, so that the light emitted by the light-emitting lamp 11 is directly emitted into the protective cover 8, which helps to improve the light emission brightness of the light-emitting lamp 11.

[0062] As another improvement, as shown in Figures 15 and 22, the generator core 5 is provided with an external power supply interface 13, which is electrically connected to the coil group of the generator core 5. The current generated by the generator core 5 is delivered to the external power supply interface 13. The external power supply interface 13 is used for connecting to the corresponding plug of the light strip. The light strip can be fixed in the hub 101 and then plugged into the external power supply interface 13, so that the current generated by the generator core 5 is output to the light strip.

[0063] As shown in Figures 7, 8, and 16, the power component 3 includes a rotating shaft 302 and a foot pedal 301. The rotating shaft 302 is integrally formed, providing good stability. The rotating shaft 302 includes a force-bearing section 3021, a middle section 3022, and an action section 3023 connected in sequence. The foot pedal 301 is connected to the force-bearing section 3021. The action section 3023 is inserted into the mounting position 201 of the connecting member 2. Since the rotation of the rotating shaft 302 drives the rotation of the connecting member 2, the front end of the action section 3023 is D-shaped, and the interior of the mounting position 201 forms a matching D-axis cavity. Inserting the front end of the action section 3023 into the mounting position 201 prevents slippage between the action section 3023 and the connecting member 2 in the rotational direction, allowing the power of the action section 3023 to be transmitted to the connecting member 2 for synchronous rotation. The action section 3023 also has a groove 30231 for installing a sealing ring, enhancing the fit between the sealing ring and the mounting position 2. The clamping force on the inner wall of 01 also enhances the synchronous rotation effect of the strengthening section 3023 and the mounting position 201 in the connecting member 2; the distance D1 between the force-bearing section 3021 and the rotation center line is 1 / 3 to 1 / 2 of the distance D2 between the wheel 1 and the rotation center line; when a child steps on the pedal 301, the force is applied to the force-bearing section 3021, so the lever arm of this force with respect to the rotation center line is D1; ​​under the premise of a fixed torque to overcome the rotation of the wheel 1, the larger the lever arm, the smaller the force, and the smaller the lever arm, the larger the force; and as can be seen from daily use, the pedal 301 is mounted on the force-bearing section 3021 by rotating through a bearing. Considering the width of the conventional pedal 301, the inventor has found that the above distance setting can ensure that the force is appropriate, that is, the wheel 1 can be rotated without a heavy force, making it easy for children to step on, and preventing the conventional pedal from scraping against the ground and affecting the stepping.

[0064] The angle θ2 between the middle section 3022 tilting outward and the vertical line on the horizontal plane is in the range of 22~32°. The angle θ2 is set under the premise that the force acting on the force-bearing section 3021 is appropriate. The outward tilting of the middle section 3022 can not only prevent the middle section 3022 itself from scraping against the outside of the front fork 6 when it rotates, but also keep the pedal 301 on the force-bearing section 3021 at a certain distance from the front fork 6, so as to prevent the child's shoes from scraping against the outside of the front fork 6 during pedaling and affecting the use.

[0065] The hub 101 has a center mounting position 1012, the outline of which matches the outer outline of the connecting member 2. The connecting member 2 is located in the mounting position. The connecting member 2 includes several side surfaces 202 located around its periphery. There are more than three side surfaces 202, meaning that the part of the connecting member 2 with side surfaces 202 can be triangular, quadrilateral, or polygonal, etc. As can be seen from Figures 3 and 12, the matching of the outline of the mounting position 1012 with the outer outline of the connecting member 2 means that the mounting position 1012 is recessed and has a resistance surface corresponding to the side surface 202. The side surface 202 and the resistance surface are face to face. All side surfaces 202 are perpendicular to the rotation plane of the wheel 1, and the several side surfaces 202 are arranged to surround the rotation center line. Therefore, when the connecting component 2 rotates, the force can be evenly transmitted to each side 202. Since the side 202 is perpendicular to the rotation plane of the wheel 1, the rotational force of the side 202 can be almost entirely directly applied to the resistance surface when it rotates. The transmission of rotational force is more thorough, avoiding the loss of force due to wasted effort, which is beneficial for the child's stepping force to be transmitted to the rotation of the wheel 1.

[0066] This invention provides a self-generating wheel structure that enables synchronous rotation of the axle and wheel without differential speed, filling a gap in the existing market for such self-generating wheels. The power component is a connecting member fixed in the wheel. The rotation of the power component drives the wheel to rotate and causes the generator core to generate current for use. This self-generating wheel structure overcomes the limitation of traditional power-generating wheels and light-emitting wheels, which can only be used in scooters, roller skates, and strollers where the central connecting axle does not need to rotate. It allows power-generating wheels and light-emitting wheels to be used on the wheels located on the front fork, such as children's tricycles, so that the wheel can generate electricity or light synchronously by rotating the wheel through pedaling.

[0067] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
