Description

A self-generating luminous wheel frame structure and cart thereof Technical Field

[0001] The utility model relates to the technical field of power-generating wheels, in particular to a self-generating and luminous wheel frame structure and a cart thereof. Background Art

[0002] Common carts today are equipped with a generator wheel to provide a light-emitting function. As the cart moves, the generator wheel rotates, generating electricity that is then fed into a light source. This type of power generation and lighting is based on the law of electromagnetic induction, discovered by British scientist Michael Faraday. The principle states that when a conductor in a closed circuit cuts through magnetic flux lines in a magnetic field, a current is generated in the conductor. This phenomenon is called electromagnetic induction, and the resulting current is called induced current.

[0003] However, the current structures for power generation and lighting all separate the generator wheel from the light-emitting component. For example, the Chinese patent document (patent number: CN202320500271.8, patent name: A self-generated light-emitting cart) discloses that it "includes a frame, at least one generator wheel is provided below the frame; a light-emitting component is provided on the frame, and the generator wheel is electrically connected to the light-emitting component; the frame includes a rod body and a support plate, the rod body includes a handle, and the support plate is hinged to the rod body; the generator wheel is rotatably connected to the bottom of the rod body. The benefit of the present invention is that when the frame is pushed or pulled, the generator wheel rotates, emitting current for the light-emitting component to emit light."

[0004] In the structure disclosed in the above patent document, the light-emitting component is arranged on the vehicle frame, that is, the current generated by the generator wheel is to be led to the vehicle frame by wires for use. However, since this design must take into account both aesthetics and practicality, it has high requirements for wiring and is complicated to install. If the generator wheel fails and affects the light emission, it needs to be replaced, and the wiring must be reconnected, which is relatively cumbersome. Technical Solutions

The first light-emitting lamp 4 is fixed in the mounting position 1011. The power generation component 3 generates current which is led out to the first light-emitting lamp 4 through the wire 11 for use.

[0039] As one embodiment, the light-emitting component includes a second light-emitting lamp 5, which is fixed at the upper end of the frame 1. In this embodiment, the second light-emitting lamp 5 is arranged in a circular shape, and the power generation component 3 generates current which is led out to the second light-emitting lamp 5 through the wire 11 for use.

[0042] In addition, the second light emitting lamp 5 is covered with a light-transmitting ring 6 , and the light emitted by the second light emitting lamp 5 will be emitted through the light-transmitting ring 6 , which also has a protective effect on the second light emitting lamp 5 .

[0043] The mounting position 1011 is detachably connected to a light-transmitting cover 9, which can be fixed to the mounting position 1011 by snap-fitting or screw-tightening. The light emitted by the first light-emitting lamp 4 will be emitted through the light-transmitting cover 9, which also has a protective effect on the first light-emitting lamp 4.

[0044] The upper end of the frame 1 is provided with a top cover 8, the middle portion of which is inserted into the insertion rod 7. A through-hole 801 is provided on the top cover 8, and screw holes are provided on the frame 1. The screw holes correspond to the positions of the through-holes 801. By passing a screw through the through-holes 801 and tightening it into the screw holes, the top cover 8 is fixed to the upper end of the frame 1. The top cover 8 seals and shields the upper end of the frame 1. As can be seen from Figure 3, the inner side of the top of the light-transmitting ring 6 is provided with a step, and the edge of the top cover 8 is pressed into the step, thereby pressing the light-transmitting ring 6.

[0045] The frame 1 includes an inner frame 101 and an outer frame 102 that are arranged in a covering manner. The inner frame 101 is provided with a first wiring position 1012, a second wiring position 1013 and a first wire hole 1014 for leading the power supply line 11; the top of the outer frame 102 is provided with a second wire hole 1021; the first wiring position 1012 and the second wiring position 1013 are slotted, so that the wire 11 can be embedded and arranged. The wire 11 led out from the power generation component 3 extends through the first wiring position 1012 to the first light-emitting lamp 4 for use. The wire 11 can also extend further upward through the second wiring position 1013, the first wire hole 1014, and the second wire hole 1021 to the second light-emitting lamp 5 and the third light-emitting lamp 10 for use, with a compact structure.

[0046] The power generation component 3 includes a mounting member 301, a winding group 302, a circuit board 303 and a magnetic ring 304.

The hub 201 is detachably provided with a side cover 202. The magnetic ring 304 is fixed to the inner wall of the side cover 202. Glue can be applied to the outer wall of the magnetic ring 304, and then embedded and fixed to the inner wall of the side cover 202. Then, screws are screwed in to fix the side cover 202 to the hub 201; the circuit board 303 and the winding group 302 are fixed to the mounting member 301. Bearings are installed at both ends of 301, the inner ring of the bearing at one end is connected and fixed to the mounting component 301, and the outer ring of the bearing is connected and fixed to the wheel hub 201, and the inner ring of the bearing at the other end is connected and fixed to the mounting component 301, and the outer ring of the bearing is connected and fixed to the side cover 202, so that the wheel hub 201 and the side cover 202 can rotate relative to the mounting component 301; the circuit board 303 and the winding group 302 are fixed to the mounting component 301 and cannot move, so that when the wheel hub 201 and the side cover 202 rotate and drive the magnetic ring 304 to rotate, the movement of cutting the magnetic lines of force occurs, so that the winding group 302 generates current, and the winding group 302 transmits the current to the circuit board 303 and finally transmits it to the light-emitting component for use.
