Description

[Technical field]

[0001] The present invention relates to a rim, and more particularly to a rim device used for wheels of two-wheeled or four-wheeled automobiles. [Background technology]

[0002] The wheels of two-wheeled and four-wheeled vehicles are filled with air between the rim and the tire. If the air pressure (hereafter referred to as tire air pressure) is insufficient, the tire will bend excessively, increasing rolling resistance and adversely affecting fuel efficiency. In addition, if air pressure management is neglected, a puncture may be noticed late, which may impair driving stability.

[0003] Therefore, the installation of a tire pressure detection device is recommended to monitor and manage tire pressure. Currently, the tire pressure detection device generally used has a sensor located on the wheel rim, and an information processing unit that analyzes the detection signal received from the sensor and displays it in an easy-to-understand manner is located on the panel side.

[0004] However, since the above-mentioned conventional tire pressure detection device does not have any means for displaying the detection results other than on the panel side, it is not possible to know the tire pressure at a glance.

[0005] Moreover, Patent Document 1 discloses a conventional rim with a display device. [Prior art documents] [Patent documents]

[Diagram 5] FIG. 2 is a cross-sectional view showing the configuration of the rim device of the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Figures 1 to 3 show an embodiment of a rim device 200 of the present invention, and by mounting a tire (not shown) to this rim device 200, a wheel suitable for mounting on a wheel shaft (not shown) of a vehicle can be formed.

[0012] In addition, the rim device 200 is configured so that a tire pressure sensor 900 can be attached. The tire pressure sensor 900 can detect the tire pressure, which is the air pressure inside the tire, and wirelessly transmit a tire pressure signal to an information processing unit (not shown) arranged in the vehicle.

[0013] The rim device 200 comprises a rim body 31 that can be fixed to the wheel shaft of a vehicle, a power generation means 4 arranged in the center of the rim body 31, a tire pressure display means 8 attached to the rim body 31 and electrically connected to the power generation means 4, a power generation section cover 32 attached to the rim body 31 so as to cover the power generation means 4 from the outside, and a plurality of transparent covers 33 arranged at intervals from each other on the side of the rim body 31 so as to surround the center of the rim body 31.

[0014] A tire and a tire pressure sensor 900 can be attached to the rim body 31, and a plurality of storage spaces 310 are formed on the side of the rim body 31 away from the central axis 40 and arranged so as to open to the outside, and the transparent cover 33 is attached to each storage space 310 so as to shield the storage space 310.

[0015] The power generating section cover 32 is attached to the center between the transparent covers 33 on the above-mentioned side surface of the rim body 31 and shields the power generating means 4 .

[0016] Detailed explanations of the specific configurations of the rim body 31, the generator cover 32, and the transparent covers 33 are omitted since they are not the point of the present invention. Naturally, they may have shapes and configurations other than those shown in the drawings.

[0017] As shown in Figures 2, 4 and 5, the power generation means 4 includes a rotor module 5 fixed to the rim body 31 so as to rotate together with the rim body 31 and electrically connected to a tire pressure display means 8, a stator module 6 attached to the rotor module 5 so as to be rotatable relative to the rotor module 5 about the central axis 40 of the wheel shaft of the vehicle to which the rim device 200 is attached, and a weight 7 fixed to the stator module 6 so that its center of gravity is located below the stator module 6, so that the stator module 6 rotates relative to the rotor module 5 when the rotor module 5 rotates together with the rim body 31.

[0018] The rotor module 5 has a holding frame 51 and a plurality of coil units 52 fixed in the holding frame 51. The holding frame 51 is fixed to the rim body 31 so as to be coaxially rotatable with the rim body 31 about the central axis 40 as a rotation axis, and has a mounting part 511 in which an opening 512 opening toward the side is formed, and a side cover 513 attached to the mounting part 511 so as to cover the opening 512. The mounting part 511, together with the side cover 513, defines an axial space 510 in which each coil unit 52 is housed. Each coil unit 52 is fixed to the mounting part 511 so as to surround the central axis 40.

[0019] The stator module 6 is configured to have an axial rod portion 61 that passes through the holding frame 51 to be rotatable relative to the mounting portion 511 and the side cover 513, and a plurality of magnets 62 that are fixed to the axial rod portion 61 and spaced apart from each other around the central axis 40 so as to be located within the axial space 510. The weight 7 passes through the side cover 513 of the axial rod portion 61 and is fixed to the mounting end portion 611 exposed to the outside of the holding frame 51.

[0020] 1 and 5, the tire pressure display means 8 comprises a wireless communication module 81 capable of receiving a tire pressure signal wirelessly transmitted from a tire pressure sensor 900, a plurality of light-emitting modules 82, and a control module 83 that is signal-connected to the wireless communication module 81 and each of the light-emitting modules 82. In this embodiment, the wireless communication module 81 is integrated onto a single circuit board together with the control module 83, and is disposed in a space shielded by the power generation unit cover 32 of the rim body 31.

[0021] Each light-emitting module 82 is accommodated in a corresponding accommodation space 310 and is shielded by a corresponding transparent cover 33. Each light-emitting module 82 can emit light in response to the control of the control module 83, and the light emitted from the light-emitting module 82 can be seen from outside the transparent cover 33.

[0022] The control module 83 is signal-connected to the wireless communication module 81 and each light-emitting module 82, and can obtain the corresponding tire pressure value by analyzing the tire pressure signal from the wireless communication module 81, and controls the light-emitting module 82 to change the light-emitting mode based on the tire pressure value.

[0023] Specifically, the control module 83 controls the brightness, color, and frequency of light emitted by each light-emitting module 82 by changing the light-emitting mode in response to changes in the tire air pressure values.

[0024] In this way, since each light-emitting module 82 is accommodated in a respective accommodation space 310 away from the central axis 40, when the wheel rotates, the light emitted by each light-emitting module 82 appears in a ring shape.

[0025] As shown in Figures 2 to 4, with the above configuration, when the rotor module 5 rotates together with the rim body 31 of the wheel running relative to the ground while the vehicle is running, the rotor module 5 becomes a rotor that rotates together with the rim body 31, and the weight 7 fixed to the stator module 6 always hangs down due to its own weight so that the center of gravity is located below the stator module 6, and the stator module 6 becomes a stator that does not rotate relative to the ground, and the power generation means 4 can generate electricity by electromagnetic induction between each coil unit 52 of the rotor module 5, which rotates relative to the ground, and each magnet 62 of the stator module 6, which does not rotate relative to the ground.

[0026] The tire pressure display means 8 is activated in response to the electricity generated by the rotor module 5, receives the tire pressure signal transmitted by the tire pressure sensor 900 (see FIG. 1), and controls the brightness, color and frequency of the light emitted by the light-emitting module 82 according to the tire pressure value corresponding to the received tire pressure signal by changing the light-emitting mode, thereby not only indicating the tire pressure but also creating an excellent visual effect.

[0027] In addition, in this embodiment, the receiving space 310 in which each light emitting module 82 is arranged is covered by the transparent cover 33, but it is also possible to leave the transparent cover 33 undone and expose each light emitting module 82.

[0028] Furthermore, in this embodiment, the tire pressure display means 8 has a plurality of light-emitting modules 82, but the present invention can be implemented with only one light-emitting module 82.

[0029] To sum up, the rim device 200 of the present invention provides the power generation means 4 and the tire pressure display means 8, and thus the tire pressure can be displayed on the tire pressure display means 8 while the vehicle is running, and the tire pressure display means 8 can emit light in a ring shape by rotating the rim device 200, creating a brilliant visual effect. Therefore, the object of the present application can be reliably achieved.

[0030] Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications are possible without departing from the gist of the present invention. [Explanation of symbols]
