[0028] Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same reference numerals.

[0029] Refer to Figure 1 、 2 A first embodiment of the rim device 200 of the present invention capable of generating electricity is suitable for mounting a tire to form a wheel and can be used for mounting on a wheel axle (not shown) of a vehicle.

[0031] The inner frame portion 31 has an outward-facing central disk surface 310 and has a central groove 311 recessed in the central disk surface 310 along the axis 30, a plurality of locking holes 312 recessed in the central disk surface 310 and spaced apart around the axis 30 on the outer peripheral side of the central groove 311, and a plurality of communication channels 313 recessed in the central disk surface 310 and extending radially outward from the central groove 311 to the respective spoke portions 33. Each locking hole 312 is adapted to receive a bolt (not shown) for locking to the wheel axle. The communication channels 313 respectively extend through the locking holes 312.

[0032] On the outer side surface of each spoke portion 33, a receiving groove 331 communicating with the corresponding communication channel 313 is concavely provided. Each receiving groove 331 can be used to receive electronic components such as LED lights (not shown in the figure) or a energy storage device (shown in the figure). The decorative plates 7 are respectively installed on the spoke portions 33 and respectively cover and shield the receiving grooves 331.

[0033] Since there are many structural types of the spoke portions 33 of the rim body 3, and the icon style of the present invention is only for illustration, during implementation, the spoke portions 33 are not limited to the icon style.

[0034] Refer to Figure 2 、 3 、4, the power generation mechanism 4 is embedded and fixed in the central groove 311 and can be driven by the rim body 3 to rotate for power generation. Since the power generation mechanism 4 is not the focus of the creation of the present invention, it will not be described in detail herein.

[0035] The covering mechanism 5 includes an annular seat unit 51 coaxially installed and fixed on the central disk surface 310 along the axis 30, and a decorative cover 54 coaxially installed and fixed on the inner peripheral side of the seat unit 51. An annular installation space 510 is defined inside the seat unit 51, and an inner ring space 511 located on its inner peripheral side and communicating with the central groove 311 is defined around. The decorative cover 54 covers and shields the inner ring space 511. The covering mechanism 5 also has a ventilation channel structure 55 provided between the seat unit 51 and the decorative cover 54 and communicating the outside with the inner ring space 511.

[0036] The seat unit 51 includes an annular inner seat 52 coaxially installed and fixed on the central disk surface 310, and an annular outer seat 53 coaxially installed and fixed on the inner seat 52. The outer seat 53 has an outer ring body portion 531 installed on the inner seat 52 and cooperating with the inner seat 52 to define the installation space 510 and the inner ring space 511, and an annular installation wall portion 532 radially protruding from the inner peripheral surface of the outer ring body portion 531 into the inner ring space 511. In this embodiment, the inner seat 52 is inserted and buckled to the rim body 3 through a plurality of buckle portions 520 spaced around the axis 30. However, during implementation, the installation and fixation method of the inner seat 52 on the rim body 3 is not limited thereto. For example, it can also be fixed by bolt screwing.

[0037] Refer to Figure 3 、 4, 5. The decorative cover 54 includes a plate body 541 installed and fixed in the inner ring space 511 at a radial interval from the outer ring body portion 531, and a plurality of fins 543 protruding from the plate body 541 toward the mounting wall portion 532 at intervals around the axis 30. The length of each fin 543 protruding toward the mounting wall portion 532 gradually increases radially inward from the outer peripheral edge of the plate body 541, and abuts against the mounting wall portion 532 at its maximum protruding length.

[0038] In this first embodiment, the plate body 541 has a plurality of fastening portions 542 distributed at intervals around the axis 30, and is installed and fixed to the outer ring seat 53 in such a way that the fastening portions 542 penetrate and fasten to the mounting wall portion 532 along the direction of the axis 30. However, in implementation, there are many ways to install and fix the plate body 541 to the outer ring seat 53, not limited to the above method. For example, it can also be fixed by bolting.

[0039] Refer to Figure 4 , 5 , 6. The breathable channel structure 55 has an annular outer ring channel 551 disposed between the outer peripheral edge of the plate body 541 and the outer ring body portion 531 and communicating with the outside, and a plurality of breathable grooves 552 disposed between the opposite sides of the fins 543 and communicating the outer ring channel 551 with the inner ring space 511. The breathable grooves 552 communicate with the central groove 311 through the inner ring space 511.

[0040] The circuit mechanism 6 is installed in the installation space 510 and can be used to convert the alternating current generated by the power generation mechanism 4 into direct current. In implementation, the circuit mechanism 6 can be electrically connected to the electronic components installed in the accommodation groove 331 for directly supplying power to drive the electronic components. For example, but not limited to, for supplying power to drive a tire pressure detector or a lighting component, etc. In implementation, the circuit mechanism 6 can also be electrically connected to the energy storage module installed in the accommodation groove 331 so that the circuit mechanism 6 stores the generated electrical energy in the energy storage module.

[0041] Refer to Figure 2 , 3 , 6. When the wheel rim device 200 of the present invention is used to make a wheel and installed on a vehicle, during the driving process of being driven to rotate, the wheel rim body 3 will drive the power generation mechanism 4 to rotate synchronously, so that the power generation mechanism 4 rotates to generate electricity. At the same time, since the breathable channel structure 55 communicates the outside with the inner ring space 511, the outside air can be introduced into the inner ring space 511 through the breathable channel structure 55, and the heat energy dissipated by the power generation mechanism 4 in the inner ring space 511 can be dissipated. In addition, part of the airflow entering the central groove 311 and the inner ring space 511 will also be dispersed into the accommodation groove 331 of the spoke portion 33 through the communication groove 313, which also helps with heat dissipation.

[0042] In this embodiment, the fin 543 is designed to extend in an arc shape from the outer peripheral edge of the plate body 541 towards the inner peripheral edge. However, in actual implementation, in another embodiment of the present invention, the fin 543 can also be designed to extend radially straight.

[0043] Refer to Figure 7 、 8 A second embodiment of the rim device 200 capable of generating electricity according to the present invention differs from the first embodiment in the structural design of the covering mechanism 5. For the convenience of description, only the differences of the embodiments will be described below.

[0044] In this second embodiment, the covering mechanism 5 includes the ring seat unit 51 and the decorative cover 54, and has the air permeable channel structure 55.

[0045] The ring seat unit 51 includes the inner ring seat 52 fixed to the central disk surface 310, and the outer ring seat 53 installed on the inner ring seat 52. The decorative cover 54 is not provided with the fins, and the decorative cover 54 is stacked and fixed to the mounting wall portion 532 of the outer ring seat 53 to cover the inner ring space 511.

[0046] The inner ring seat 52 has an annular inner ring body portion 521 installed on the inner frame portion 31 and having an inner ring side surface 522 facing the central disk surface 310, and a plurality of fin portions 523 extending from the inner ring side surface 522 towards the central disk surface 310 at intervals around the axis 30. Each fin portion 523 abuts against the central disk surface 310 and extends from the outer peripheral edge to the inner peripheral edge of the inner ring body portion 521.

[0047] The air permeable channel structure 55 has a plurality of air permeable grooves 552 respectively located between the opposite sides of the fin portions 523, communicating the outside with the inner ring space 511. The air permeable grooves 552 will communicate with the central groove 311 through the inner ring space 511, and some of the air permeable grooves 552 communicate with the communication grooves 313.

[0048] During the process of the rim device 200 capable of generating electricity according to the present invention being driven to rotate and generate electricity, the heat generated by the power generation mechanism 4 can also be assisted in dissipating through the structural design of the air permeable grooves 552 of the air permeable channel structure 55, and the communication grooves 313 connecting the air permeable grooves 552 and the inner ring space 511 can also be used to assist in heat dissipation.

[0049] Refer to Figure 9 、 10 A third embodiment of the rim device 200 capable of generating electricity according to the present invention differs from the second embodiment in the structural design of the inner ring seat 52 and the air permeable channel structure 55.

[0050] In this third embodiment, the fin portion is not provided on the inner ring seat 52, and the inner ring side surface 522 of the inner ring body portion 521 abuts against the central disk surface 310.

[0051] The ventilation channel structure 55 has a plurality of ventilation grooves 552 that are spaced apart around the axis 30 and are recessed in the inner ring side surface 522 of the inner ring body portion 521. Each ventilation groove 552 extends from the outer peripheral edge to the inner peripheral edge of the inner ring body portion 521 to communicate the outside with the inner ring space 511, and some of the ventilation grooves 552 communicate with the communication groove 313.

[0052] Through the structural design of the ventilation grooves 552 of the ventilation channel structure 55, it can also be used to dissipate the heat energy generated by the operation of the power generation mechanism 4.

[0053] It must be noted that in the above-mentioned embodiments, during implementation, it is not necessary for the rim body 3 to be provided with the communication groove 313 and the accommodation groove 331, and when the accommodation groove 331 is not provided, the decorative plate 7 is not necessary either.

[0054] In summary, through the structural design of the ventilation channel structure 55 of the covering mechanism 5 installed on the rim body 3, during the power generation process in which the power generation mechanism 4 is driven to rotate by the rim body 3, the heat energy generated by the power generation mechanism 4 can be effectively dissipated, and the situation of overheating of the power generation mechanism 4 can be avoided. Therefore, the rim device 200 of the present invention is indeed a quite innovative, convenient and practical creation, and can indeed achieve the purpose of the present invention.

[0055] The above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. All simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still belong to the scope of the present invention.
