Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of power generation wheel, especially a novel self power generation wheel body structure of axle wheel no differential synchronous rotation. BACKGROUND

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

[0003] There are many types of power generation devices, and rotating generator core is one of the common types. 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, roller skates, trolleys, bicycles and the like, so that the rotating wheels generate electricity during walking and power the connected components to achieve lighting or other entertainment effects.

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.

DETAILED DESCRIPTION

[0046] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used for illustrating and explaining the utility model, and are not used for limiting the utility model.

[0047] As shown in the drawings, Figures 1 to 6 The utility model discloses a novel self-generating wheel body structure of differential-free synchronous rotation of axle wheel, which aims at enabling the rotating shaft rod 302 in the middle to drive the rotation of the wheel 1 when rotating, and the angular velocities of the rotation of the rotating shaft rod 302 and the wheel 1 are the same, and the wheel 1 can generate electricity for use in the process of walking. The self-generating wheel body structure can be applied to the wheel body located at the front fork of a tricycle as a representative, and therefore the wheel body is driven to rotate by the rotation of the pedal. At present, there is no such generating wheel disclosed.

[0048] Specifically, the self-generating wheel body structure comprises a fixed component and a rotatable component which are coupled; the rotatable component comprises a wheel 1, and the wheel 1 comprises a wheel hub 101 and a tire 102 wrapped outside the wheel hub 101; a connecting member 2 is arranged in the rotatable component, and the connecting member 2 is connected to the center of the wheel hub 101; after the connecting member 2 is connected to the wheel hub 101, the wheel hub 101 and the connecting member 2 do not slip; the connecting member 2 is provided with a mounting position 201 for mounting a power component 3, the power component 3 is connected to the mounting position and fixed to 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 in turn 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 the wheel 1, so that the rotation force generated by the connecting member 2 when it is forced to rotate can be evenly transmitted to the wheel 1 to drive the wheel 1 to rotate; as will be described below, the power component 3 is driven by the foot, so that the central axis of the wheel 1 and the connecting member 2 coincides with the rotation center line of the power component 3, which not only helps the power component 3 to transmit the rotation force 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 arm changes when the wheel 1 walks, which causes the resistance (the stepping force of the child) to change, or the wheel 1 walks and jolts due to the 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, so that the wheel 1 is vertically arranged when it is fixed to the child's car, and the above arrangement is beneficial to the rotation of the power component 3 to drive the wheel 1 to move forward and backward.

[0050] The combination of the fixed component and the rotatable component is provided with a corresponding magnetic ring 4 and a generator core 5; the rotatable component rotates relative to the fixed component, so that the generator core 5 and the magnetic ring 4 rotate relative to each other to cut the magnetic force line to generate current. According to the prior art, the generator core 5 includes coil groups, circuit boards and other components, and the relative rotation of the magnetic ring 4 and the coil groups in the generator core 5 cuts the magnetic force line 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 Figures 1 to 6 , it is a specific introduction of the self-generating wheel body, the generator core 5 is fixedly installed on the fixed component, and the magnetic ring 4 is fixedly installed on the connecting member 2; specifically, the fixed component includes a front fork 6, the front fork 6 is part of the child's car, the lower end of the front fork 6 is connected with an end cover 7, 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, the boss 501 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 lamp, horn or other low power electrical instruments) on the child's car for use, so that the structure further includes an outgoing wire 12, the inner end of the outgoing wire 12 is connected with the generator core 5, and the outer end of the outgoing wire 12 is upward through the internal space of the end cover 7 and the front fork 6; therefore, the generator core 5 is in a fixed state, avoiding the phenomenon that the generator core 5 rotates to cause the outgoing wire 12 to be wound.

[0053] A protective cover 8 is connected to the side of the hub 101. A convex ring 801 is formed in the middle of the protective cover 8. The magnetic ring 4 is embedded in the convex ring 801 and is used in a corresponding and matching manner with the generator core 5. That is, when the wheel 1 is moving, it drives the magnetic ring 4 to rotate relative to the generator core 5 to generate electricity. The function of the protective cover 8 is to prevent foreign objects from entering the hub 101 and causing damage.

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

[0055] like Figures 9 to 16 The diagram illustrates a first embodiment of this 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 center 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] like Figures 17 to 21 The image shows a detailed description of the first embodiment of this self-generating wheel, which 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, with a connector 10 at its lower end. The inner side of the connector 10 extends towards the center of the hub 101. The magnetic ring 4 is connected to the connector 10, and the power component 3 is rotatably disposed within the connector 10. A key difference between this embodiment and the first embodiment is that... Figure 18 It can be seen that a channel is provided in the middle of the connector 10, and the rotation of the power component 3 is set in the channel. There is no bearing. The generator core 5 is set in the middle of the hub 101 and is matched with the magnetic ring 4.

[0059] But no matter the first embodiment or the second embodiment, the generator core 5 and the wheel hub 101 can be integrally provided, or the generator core 5 is detachably fixed in the wheel hub 101, that is, the generator core 5 is fixed in the integrally formed wheel hub 101, and when the wheel hub 101 is made, the generator core 5 is put into the mold to form the wheel hub 101 by integral injection molding, and the generator core 5 is wrapped in the wheel hub 101, which will make the stability of the generator core 5 in the wheel hub 101 better and less likely to loosen; or, the wheel hub 101 is formed with a mounting port 1011 for assembling the generator core 5, and the circumferential direction of the mounting port 1011 is provided with a fixing groove 10111, and the axial direction of the generator core 5 is provided with a convex edge 502, when the generator core 5 is assembled to the mounting port 1011, the convex edge 502 is inserted into the fixing groove 10111 for limiting, so as to limit the relative rotation of the generator core 5 and the wheel hub 101; this structure is to put the generator core 5 into the installation after the wheel hub 101 is made, although this structure is not as stable as the above-mentioned integral molding, but the generator core 5 will not be easily damaged by soaking in high-temperature raw materials during the injection molding of the wheel hub 101, so there are advantages and disadvantages, and the actual process and cost can be selected.

[0060] As shown in Figure 13 , a plurality of light emitting lamps 11 are equidistantly distributed on the outer periphery of the generator core 5; the range of the included angle θ1 between adjacent light emitting lamps 11 is 55-65°, and the setting of the above-mentioned included angle allows the number of light emitting lamps 11 to be kept at about 5-7, so the inventor has found that this number can already meet the requirements that the light emitting lamps 11 form a light ring in the rotating state after the light emitting lamps 11 are bright when the wheel 1 rotates at a low speed, and the number of light emitting lamps 11 is not too small to achieve the desired effect, nor is the number of light emitting lamps 11 too large to increase the production cost and reduce the marginal effect.

[0061] The light emitting lamp 11 can be arranged towards the outer periphery of the wheel 1 as shown in Figure 13 , so that the light is irradiated on the channel of the wheel hub 101 and then emitted through the protective cover 8; in the structure of the self-generating wheel body as a light-emitting wheel, the protective cover 8 is made of light-transmitting material, which not only has the effect of protection inside, but also is beneficial to the emission of light; or, the light emitting lamp 11 is perpendicular to the rotating plane of the wheel 1 towards one side of the protective cover 8, that is, the light emitted by the light emitting lamp 11 is directly emitted in the protective cover 8, which helps to improve the light efficiency and brightness of the light emitting lamp 11.

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

[0063] As shown in Figure 7 , Figure 8 and Figure 16 , the power component 3 includes the rotating shaft rod 302 and the pedal 301; the rotating shaft rod 302 is integrally formed and has good stability; the rotating shaft rod 302 includes the stress section 3021, the middle section 3022 and the action section 3023 connected in sequence, and the pedal 301 is connected to the stress section 3021; the action section 3023 is inserted and installed in the installation position 201 of the connecting component 2; since the rotation of the rotating shaft rod 302 drives the rotation of the connecting component 2, the front end of the action section 3023 is in the shape of a D shaft, the inside of the installation position 201 is formed with a D shaft insertion cavity matched with the D shaft, the front end of the action section 3023 is inserted into the installation position 201, so that the action section 3023 and the connecting component 2 do not slip in the rotation direction, and the power of the action section 3023 during rotation can be transmitted to the connecting component 2 to synchronously rotate; the action section 3023 is also provided with a groove 30231 for installing a sealing ring, so as to enhance the pressing force of the sealing ring with the inner wall of the installation position 201 after installation, and also enhance the synchronous rotation effect of the action section 3023 with the installation position 201 of the connecting component 2; the distance D1 between the stress section 3021 and the rotation center line is 1 / 3-1 / 2 of the distance D2 between the wheel 1 and the rotation center line; when the child pedals the pedal 301, the force is applied to the stress section 3021, so the force arm of the force to the rotation center line is D1; under the premise of a fixed torque to overcome the rotation of the wheel 1, the greater the force arm, the smaller the force, and the smaller the force arm, the greater the force; and as known from daily use, the pedal 301 is rotatably assembled on the stress section 3021 by a bearing, and under the premise of comprehensively considering the width of the conventional pedal 301, the inventor finds that the above distance setting can not only ensure that the force is appropriate, that is, the wheel body 1 can be rotated without heavy force, but also make it easy for children to pedal, and the conventional pedal will not be scratched with the ground during use to affect the pedaling.

[0064] The angle θ2 between the middle section 3022 and the vertical line on the horizontal plane is in the range of 22-32°, and the angle θ2 is set on the premise that the force acting on the force receiving section 3021 is appropriate, so that the outward inclination of the middle section 3022 not only avoids scratching the outer side of the front fork 6 when the middle section 3022 rotates, but also keeps the pedal 301 on the force receiving section 3021 away from the front fork 6, so as to avoid scratching the outer side of the front fork 6 by the child's shoes during pedaling and affecting use.

[0065] The hub 101 is provided with an assembly position 1012 in the center, the assembly position 1012 is matched with the outer contour of the connecting member 2, and the connecting member 2 is located in the assembly position; the connecting member 2 includes a plurality of side surfaces 202 located on the periphery, the number of the side surfaces 202 is more than three, that is, the part of the connecting member 2 where the side surfaces 202 are located can be triangular, quadrangular or polygonal; from Figure 3 and Figure 12 As can be seen, the assembly position 1012 is recessed to form a resistance surface corresponding to the side surface 202, and the side surface 202 corresponds to the resistance surface; all the side surfaces 202 are perpendicular to the rotation plane of the wheel 1, and the plurality of side surfaces 202 are arranged around the rotation center line. Therefore, when the connecting member 2 rotates, the force can be evenly transmitted to each side surface 202, and since the side surface 202 is perpendicular to the rotation plane of the wheel 1, that is, the rotational force of the side surface 202 can be directly applied to the resistance surface during rotation, the transmission of the rotational force is more complete, avoiding the loss of useless work, and facilitating the transmission of the child's pedaling force to the rotation of the wheel 1.
