However, the current practice is that these electrical components are powered by dry batteries or electronic batteries installed on the car. As we know, the capacity of dry batteries and electronic batteries is limited, and the batteries need to be frequently replaced during use, and the waste batteries will cause certain pollution to the environment, which can no longer meet people's increasing environmental protection awareness. Therefore, it is necessary to improve the current type of toy cars so that they can automatically generate a certain amount of electric energy when sliding to provide electric energy for the electrical components on them. Therefore, people have developed power generation wheels.

[0003] The power generation wheel generally includes a magnetic ring and a winding coil group. During the movement of the power generation wheel, the magnetic ring and the winding coil group rotate relative to each other, forming a movement of cutting magnetic induction lines to generate current, and the current is transmitted to the electrical components for use. The current basic method is to connect the winding coil group of the power generation wheel to the electrical components with wires. However, this method is prone to wire entanglement in the universal power generation wheel. Therefore, it is necessary to develop a conductive structure for the universal power generation wheel to overcome the above defects. Content of the Utility Model

Detailed implementation manners

[0026] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0027] As Figures 1 to 6 shown, a conductive structure of a universal power generation wheel includes a wheel carrier 1. A power generation wheel 2 is rotatably arranged on the wheel carrier 1. The power generation wheel 2 is a power generation wheel with a structure that can output the current generated during rotation for external use and has been publicly disclosed. A fixed column 3 is arranged on the wheel carrier 1. A first connecting piece 4, an insulating sleeve 5, and a first bearing 6 are installed on the fixed column 3. A second connecting piece 8 and a second bearing 9 are installed on the insulating sleeve 5. The insulating sleeve 5 is made of rubber material and has an insulating function; the fixed column 3, the first connecting piece 4, the first bearing 6, the second connecting piece 8, and the second bearing 9 are all made of conductive materials, for example, metal materials such as copper or steel can be used; in combination with Figures 2 to 4It can be seen that the first connecting member 4 and the first bearing 6 are directly inserted into the fixed column 3, and the first connecting member 4, the first bearing 6 and the fixed column 3 are physically connected, so the current of the first connecting member 4, the fixed column 3 and the first bearing 6 can be conducted; after the first connecting member 4 is installed on the fixed column 3, the second connecting member 8 and the second bearing 9 are installed on the insulating sleeve 5 above the first connecting member 4 (that is, the inner rings of the second connecting member 8 and the second bearing 9 match the outer diameter of the insulating sleeve 5), the second connecting member 8 and the second bearing 9 are directly connected, the two can conduct current, and the insulating sleeve 5 isolates the current conduction between the fixed column 3 and the second connecting member 8 and the second bearing 9.

[0028] It is known from the prior art that the generator wheel 2 has a coil group inside, and the internal coil group of the generator wheel 2 will generate current when it moves. One of the electrodes of the coil group (for example, the positive electrode) is electrically connected to the first connecting piece 4, and the other electrode of the generator wheel 2 (for example, the negative electrode) is electrically connected to the second connecting piece 8; one of the electrodes of the electrical instrument 12 is electrically connected to the first bearing 6, and the other electrode of the electrical instrument 12 is electrically connected to the second bearing 9; that is, the coil group of the generator wheel 2, the first connecting piece 4, the fixing column 3, the first bearing 6, the electrical instrument 12, the second bearing 9, and the second connecting piece 8 form a current closed loop, so the current generated by the coil group of the generator wheel 2 is transmitted to the electrical instrument 12 for use.

[0029] Combination Figure 3 as well as Figure 4 It can be seen that the insulating sleeve 5 is located above the first connecting member 4; the insulating sleeve 5 has a bottom ring edge 501, and a spring 7 is installed in the insulating sleeve 5, the lower end of the spring 7 is connected to the bottom ring edge 501, and the upper end of the spring 7 is connected to the second connecting member 8; in this embodiment, the setting of the spring 7 helps to separate the first connecting member 4 and the second connecting member 8 so that the two will not conduct electricity.

[0030] A slot 301 is provided on the fixing column 3. After the first bearing 6 is installed, a shaft retaining ring 10 is installed above the first bearing 6 so that the shaft retaining ring 10 is fixed in the slot 301 to prevent the first bearing 6 from escaping outwards. In actual design, a threaded section may be provided at the upper end of the fixing column 3. A nut may then be screwed into the threaded section until the inner ring of the first bearing 6 is supported, thereby also achieving a fixing effect.

[0031] The inner part of the wheel frame 1 has an inner frame 101. Embedding positions 1013 are arranged on both sides of the inner frame 101. The embedding positions 1013 are correspondingly assembled at the middle position of the power generation wheel 2. In practice, the middle position of the power generation wheel 2 is the inner ring of the bearing, and the embedding positions 1013 are embedded and assembled in the inner ring of the bearing; a wire groove 1011 is opened above the embedding positions 1013, and a wire bobbin pin 1012 is arranged at the top of the inner frame 101. The wire groove 1011 communicates with the wire bobbin pin 1012; the wires at both poles of the coil group of the power generation wheel 2 will pass through the wire groove 1011, then penetrate from below the wire bobbin pin 1012, and then pass out from above the wire bobbin pin 1012, and then are respectively connected to the first connecting piece 4 and the second connecting piece 8. As Figure 5 shown, in this structure, there are two wire bobbin pins 1012, which is beneficial for the inner frame 101 to be inserted upward into the wheel frame 1 body for positioning and installation.

[0032] It includes a mounting frame 11, and an electrical appliance 12 is fixed on the mounting frame 11; the electrical appliance 12 can be a small electrical component such as a light-emitting lamp or a horn. In this embodiment, the electrical appliance 12 is a light-emitting lamp, and the current generated by the power generation wheel 2 is transmitted upward to make the light-emitting lamp emit light.

[0033] In this embodiment, when the wheel frame 1 is fixed to the mounting frame 11, the first bearing 6 and the second bearing 9 are embedded in the mounting frame 11. The mounting frame 11 is reserved with a cavity for placing the first bearing 6 and the second bearing 9, so that the first bearing 6 and the second bearing 9 are in a separated state as Figure 1 shown, and the two will not be in contact and conduct electricity; the electrical appliance 12 includes a circuit board 1201, and the circuit board 1201 is fixed in the mounting frame 11. As can be seen from Figure 6 this, there is also a preset position in the mounting frame 11 for the circuit board 1201 to be inserted and fixed; the inner ring of the first bearing 6 is connected to the fixing column 3, the inner ring of the second bearing 9 is connected to the insulating sleeve 5, and the outer rings of the first bearing 6 and the second bearing 9 are both fixed to the inner wall of the cavity reserved by the mounting frame 11. The lower end of the fixing column 3 is fixed to the wheel frame 1. Therefore, the first bearing 6 and the second bearing 9 can enable the wheel frame 1 to rotate relative to the mounting frame 11.

[0034] Metal sheets 12012 are connected to the positive and negative poles of the circuit board 1201 respectively, and the metal sheets 12012 are respectively connected to the outer rings of the first bearing 6 and the second bearing 9 to make the electricity connected and conduct electricity; in practice, capacitors, rectifiers, and voltage regulators are also arranged in the circuit board 1201 to achieve the functions of filtering, converting alternating current into direct current and stably outputting, so as to improve the stability of power transmission and use of the power generation wheel 2; an IC control board can also be arranged, and the program preset in the IC control board will control the lighting effect of the light-emitting lamp.

[0035] The circuit board 1201 is also provided with a plug interface 12011 so that other small electrical components can be installed as needed. The plug can be directly inserted into the plug interface 12011, which is very convenient.

[0036] A capacitor 12013 is also provided on the circuit board 1201. The capacitor 12013 can store electricity. The current generated when the generator wheel 2 rotates will be transmitted to the capacitor 12013 for storage. When the generator wheel 2 stops, the stored electricity in the capacitor 12013 will be output to the light to maintain power consumption for a period of time.

[0037] like Figure 8 As shown, it is a schematic diagram of another structural form of the wheel frame 1, on which a light 102 is arranged, and the light 102 is electrically connected to the generator wheel 2; that is, the current generated by the generator wheel 2 can be transmitted to the electrical instrument 12 in the mounting frame 11 through the joint action of the fixing column 3, the first connecting member 4, the first bearing 6, the second connecting member 8 and the second bearing 9, and can also be simultaneously transmitted to the light 102 installed on the wheel frame 1 for use. The light 102 is directly arranged on the wheel frame 1, and there is no problem of wire entanglement when the wheel frame 1 rotates.

[0038] like Figure 7 As shown, the utility model also requests protection for a cart, including the universal generator wheel conductive structure mentioned above. When the cart is in use, the universal generator wheel conductive structure is adopted, and there will be no problem of wire entanglement.
