Referring to FIGS. 1 to 3, the electronic device control button in accordance with an exemplary embodiment of the present invention is applicable to a control device of an electronic device mounted inside the vehicle, for example, a sound device and a navigation device.
Referring to FIGS. 1 to 3, the electronic device control button in accordance with an exemplary embodiment of the present invention includes a jog-shuttle 3, a base part 3a, a return spring 5, and a sliding part 7.
The jog-shuttle 3 is a control button to control various electronic devices including a navigation device (not shown) for the vehicle in a rotation and push scheme.
For example, the jog-shuttle 3 is provided on a center fascia panel 1 and may control the electronic devices in a rotation and push scheme.
Further, the base part 3a supports the jog-shuttle 3, and may be slidably moved on the center fascia panel 1 in upward and downward directions, that is, may be slidably installed in a reference position.
In addition, a clearance space 3b is formed on the base part 3a and the center fascia panel 1 so that the base part 3a may be slidably moved in the vertical direction.
In this case, the reference position signifies a home position state of the jog-shuttle 3 which may adjust a volume of the electronic device through the jog-shuttle 3 when a map function of a navigation device (not shown) maintains initialization.
Moreover, the return spring 5 is installed at the center fascia panel 1, and limits an upward movement of the jog-shuttle 3 and recovers the jog-shuttle 3 to the reference position.

In addition, the guide pins 7b are provided at both sides of the base part 3a, respectively, and are slidably coupled with the sliders 7a, respectively.
Furthermore, the slider 7a is formed therein with a guide groove 7c for guiding the relative movement of the guide pin 7b. 
FIG. 5 is a schematic view illustrating a contact state and a separated state of a contact point on a printed circuit board (PCB) by moving the electronic device control button of the vehicle in accordance with an exemplary embodiment of the present invention.
Referring to FIG. 5, a terminal part 11 in accordance with an exemplary embodiment of the present invention is provided at the jog-shuttle 3, and makes contact with or is separated from a slot of a PCB 9 to apply and block different electrical signals to and from the electronic device.
In this case, the PCB 9 is a signal processor which processes an electrical signal for controlling the overall operation of the electronic device, volume, and display.
The terminal part 11 includes a first terminal part 11a, a second terminal part 11b, and a third terminal part 11c. 
When the jog-shuttle 3 is located at the reference position, the first terminal part 11a makes contact with a first slot 9a of the PCB 9 for supplying power. Alternatively, when the jog-shuttle 3 is slidably moved upward from the reference position, the first terminal part 11a makes contact with the first slot 9a of the PCB 9.
In contrast, when the jog-shuttle 3 is slidably moved in upward and downward directions, the second terminal part 11b makes contact with and is separated from a second slot 9b of the PCB 9 to which an electrical signal for adjusting a volume of the electronic device of the vehicle is applied.
When the jog-shuttle 3 is located at the reference position, the second terminal part 11b makes contact with the second slot 9b. When the jog-shuttle 3 is slidably moved in the upward direction from the reference position, the second terminal part 11b is separated from the second slot 9b. 
Further, when the jog-shuttle 3 is slidably moved in upward and downward directions, the third terminal part 11c makes contact with or is separated from a third slot 9c of the PCB 9 to which an electrical signal for controlling extension and reduction of a display size of the electronic device, that is, a map of a navigation device.
When the jog-shuttle 3 is slidably moved in the upward direction from the reference position, the third terminal part 11c makes contact with the third slot 9c. When the jog-shuttle 3 is moved to the reference position from the upward direction, the third terminal part 11c is separated from the third slot 9c. 
Hereinafter, a control state of the electronic device control button of the vehicle in accordance with an exemplary embodiment of the present invention will be described in detail with reference to FIG. 3 and FIG. 5.
First, at normal times, the jog-shuttle 3 is located in the reference position, and the second terminal part 11b makes contact with the second slot 9b of the PCB 9.
In this case, the driver may control the volume of the electronic device by rotating the jog-shuttle 3 without moving the jog-shuttle 3 from the reference position while driving the vehicle.
Meanwhile, when there is a need to control the display size of the electronic device, for example, when the driver needs to reduce and extend the navigation map (not shown) while driving the vehicle, the driver slidably moves the jog-shuttle 3 located at the reference position in the upward direction of the center fascia panel 1.
In this case, the base part 3a is slidably moved in the upward direction through the clearance space 3b formed on the base part 3a and the center fascia panel 1.
Further, when the base part 3a is moved, the guide pin 7b is moved from the slider 7a and the jog-shuttle 3 is slidably moved in the upward direction from the reference position.
In this case, if the jog-shuttle 3 is slidably moved, the return spring 5 is compressed in the upward direction to limit the upward movement of the jog-shuttle 3.
As described above, when the jog-shuttle 3 is slidably moved in the upward direction, the third terminal part 11c makes contact with the third slot 9c of the PCB 9.
When the electrical signal for controlling the display size of the electronic device is applied to the third terminal, the driver may control the display size of the electronic device by rotating the jog-shuttle 3.
In this case, an electrical signal for controlling a size of a map of a navigation device (not shown) mounted in the vehicle is applied to a display of the electronic device so that the size of the map in the navigation device may be adjusted.
Further, if the driver removes the force from the jog-shuttle 3, the control of the display size in the electronic device is terminated.
Accordingly, the jog-shuttle 3 is moved to the reference position from the upward direction due to the elastic restoring force of the return spring 5 and a contact point of the third terminal part 11c is separated from the third slot 9c. 
Next, when the jog-shuttle 3 is moved to the reference position, the second slot 9b of the PCB 9 makes contact with the second terminal part 11b. 
In this way, if the jog-shuttle 3 is moved to the reference position, the driver may control the volume of the electronic device by merely rotating the jog-shuttle 3 without slidably moving the jog-shuttle 3.
In this case, the volume of the navigation device and the volume of the sound device may be controlled by applying an electrical signal for controlling the volume of the navigation device (not shown) mounted inside the vehicle and an electrical signal for controlling the volume of the sound device as the electrical signal for controlling the volume of the electronic device.
As is seen from the forgoing description, the electronic device control button of the vehicle in accordance with an exemplary embodiment of the present invention allows the driver to conveniently and rapidly control other functions in addition to playback and volume adjustment of the electronic device by slidably moving the jog-shuttle 3.
Further, since the driver may rapidly and safely control a map reduction and extension function of the electronic device such as the navigation device by vertically moving the jog-shuttle, convenience of the driver may be improved.
An exemplary embodiment of the present invention is disclosed herein, but the present invention is not limited to the disclosed embodiments, and, on the contrary, is intended to cover various modifications and equivalent arrangements included within the appended claims and the detailed description and the accompanying drawing of the present invention.
