ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a dial device, and more particularly to a dial device for a steering wheel of an automobile co-operating with a mobile telephone.
2. Description of the Related Art
A conventional mobile telephone having a hand-free receiver in accordance with the prior art is mounted in an automobile so that the driver in the automobile can perform the dialogue function during driving the steering wheel of the automobile without having to hold the mobile telephone during driving.
However, the driver still has to press the press buttons on the mobile telephone for performing a dial function whereby the driver's hand has to leave the steering wheel so as to press the press buttons while the driver has to turn around his head to watch the numbers on the press buttons for dialing the correct telephone numbers so that the drive's view of sight will deviate the direction of travel of the automobile, thereby easily causing danger to the driver during driving.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a dial device for a steering wheel of an automobile comprising:
a steering wheel having an annular frame; and
an annular film keyboard tightly mounted on the annular frame of the steering wheel and including a connecting terminal connected to a wireless emitter so that the annular film keyboard supplies a pressing dial signal which is transmitted to a main processor through the wireless emitter in a wireless transmission manner;
wherein, the annular film keyboard co-operates with the steering wheel so that a driver can hold the steering wheel and can press the annular film keyboard so as to dial synchronously, thereby achieving a dial function.
The dial device further comprises a plurality of equally spaced elastic press button switches mounted on the annular film keyboard.
According to an embodiment of the present invention, the wireless emitter is bonded on the annular frame of the steering wheel by a snap member.
According to an embodiment of the present invention, the main processor is connected to a mobile telephone by an interface card.
In such a manner, the dial device is installed on the steering wheel whereby the driver can hold the steering wheel, and can press the press button switches of the annular film keyboard synchronously so as to perform the dial function so that the driver's hand does not have to leave the steering wheel for performing the dial function, thereby greatly enhancing the driver's safety during driving the steering wheel.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
