Description
Technical field
The utility model relates to a kind of light-emitting device, especially a kind of automotive hub light-emitting device be arranged on automobile.
Background technology
In the safety traffic field, the Wheel luminous of automobile can not only play the effect of decoration, can also play side-marker lamp's warning function simultaneously, yet because wheel is rotaryed connection with car body, usually the realization of Wheel luminous function need to be by being built in the storage battery power supply in wheel, and not only fluorescent lifetime is short for this, needs frequent charge or replacing and cause using trouble, and increased the weight of wheel, with the theory of present pursuit lightweight wheel hub, run in the opposite direction.The way of another possibility is to use the power supply of vehicle itself, but power transmission is become again to a difficult point to the light source on wheel hub.
The utility model content
In order to solve the shortcoming that overcomes prior art, the utility model proposes a kind of wheel hub light-emitting device of the wireless power transmission based on the coupling of magnetic field resonance, can supportingly be arranged on automotive hub and realize the wheel hub lighting function.
The technical solution adopted in the utility model can be described as:
A kind of automotive hub light-emitting device, comprise the LED light source that is fixed on the automotive hub outside and the light-emitting device power supply that is arranged on car body and is connected with automotive battery, wherein said LED light source is connected with the light-emitting device power supply by the power transmission module, described power transmission module comprises a plurality of output primary and a plurality of primary windings that are coupled with described output primary, wherein said output primary arranges the automotive hub inboard and is connected with LED light source, and primary winding is arranged on car body and is connected with the light-emitting device power supply, described device also comprises the solar cell be arranged on automotive hub, described solar cell is connected with LED light source.
As a kind of improvement of above technical scheme, described output primary automotive hub center shaft relative to primary winding is coaxially arranged.
As a kind of improvement of above technical scheme, described light-emitting device power supply is converted into high-frequency alternating current for the electric power transport module by the direct current (DC) of automotive battery.
The beneficial effects of the utility model are:
The light-emitting wheel hub that the utility model proposes utilizes the magnetic field Wireless power transmission by a plurality of coils of mutual coupling, is aided with solar cell for supplying power, has avoided the drawback that storage battery is set in wheel hub or conducts electricity by contact, and reliable in structure is durable.
The accompanying drawing explanation
Fig. 1 is principle schematic of the present utility model.
The specific embodiment
The utility model proposes a kind of automotive hub light-emitting device, can supportingly be arranged on automotive hub and realize the wheel hub lighting function.In exemplary concrete an enforcement, this device comprises the LED light source 1 that is fixed on the automotive hub outside and is arranged on car body and the light-emitting device power supply 3 be connected with automotive battery 2.In this embodiment, LED light source 1 can adopt a plurality of LED lamp pearls to form multiple different pattern or shape.
LED light source is connected with light-emitting device power supply 3 by power transmission module 4, described power transmission module 4 comprises a plurality of output primary 41 and a plurality of primary windings 42 that are coupled with described output primary, wherein said output primary 41 arranges the automotive hub inboard and is connected with LED light source 1, and primary winding 42 is arranged on car body and is connected with light-emitting device power supply 2, described device also comprises the solar cell 5 be arranged on automotive hub, described solar cell 5 is connected with LED light source 1, as automobile electric is battery-powered, supplements.
Further, output primary 41 is coaxially arranged with the preferred relative automotive hub center shaft of primary winding 42.
In the utility model, light-emitting device power supply 3 is connected with the storage battery of automobile, direct current (DC) is converted into to high-frequency alternating current for electric power transport module 4.
In sum, the wheel hub light-emitting device that the utility model proposes utilizes the magnetic field Wireless power transmission by a plurality of coils of mutual coupling, is aided with solar cell for supplying power, has avoided the drawback that storage battery is set in wheel hub or conducts electricity by contact, reliable in structure is durable, is worthy to be popularized.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
