       FIG. 1  is a front view illustrating a movement of an electronic device control button of a vehicle in accordance with an exemplary embodiment of the present invention,  FIG. 2  is a rear view illustrating a center fascia panel of an electronic device control button in accordance with an exemplary embodiment of the present invention, and  FIG. 3  is a rear view illustrating a moved state of the electronic device control button on the center fascia panel in accordance with an exemplary embodiment of the present invention. 
     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  3   a , 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  3   a  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  3   b  is formed on the base part  3   a  and the center fascia panel  1  so that the base part  3   a  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 this case, the return spring  5  is bent toward the base part  3   a  and a bent portion of the return spring  5  makes contact with the jog-shuttle  3 . 
     For example, the return spring  5  may include a plate spring having a plate shape which is bent toward to the base part  3   a.    
     That is, when the jog-shuttle  3  is slid upward by an external force, the return spring  5  is compressed in the upward direction by the jog-shuttle  3  to limit the upward movement of the jog-shuttle  3 . 
     In addition, if the external force is removed from the jog-shuttle  3 , the return spring  5  moves the jog-shuttle  3  in the downward direction to the reference position due to an elastic restoring force. 
       FIG. 4  is a cross-sectional view taken along line A-A of the center fascia panel of an electronic device control button in accordance with an exemplary embodiment of the present invention. 
     Referring to  FIG. 3  and  FIG. 4 , the sliding part  7  in accordance with an exemplary embodiment of the present invention is provided between the base part  3   a  and the center fascia panel  1  and slidably moves the jog-shuttle  3  in upward and downward directions. 
     The sliding part  7  includes sliders  7   a  and guide pins  7   b.    
     The sliders  7   a  are provided at both sides of the center fascia panel  1  corresponding to right and left sides of the base part  3   a , respectively. 
     In addition, the guide pins  7   b  are provided at both sides of the base part  3   a , respectively, and are slidably coupled with the sliders  7   a , respectively. 
     Furthermore, the slider  7   a  is formed therein with a guide groove  7   c  for guiding the relative movement of the guide pin  7   b.    
       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  11   a , a second terminal part  11   b , and a third terminal part  11   c.    
     When the jog-shuttle  3  is located at the reference position, the first terminal part  11   a  makes contact with a first slot  9   a  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  11   a  makes contact with the first slot  9   a  of the PCB  9 . 
     In contrast, when the jog-shuttle  3  is slidably moved in upward and downward directions, the second terminal part  11   b  makes contact with and is separated from a second slot  9   b  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  11   b  makes contact with the second slot  9   b . When the jog-shuttle  3  is slidably moved in the upward direction from the reference position, the second terminal part  11   b  is separated from the second slot  9   b.    
     Further, when the jog-shuttle  3  is slidably moved in upward and downward directions, the third terminal part  11   c  makes contact with or is separated from a third slot  9   c  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  11   c  makes contact with the third slot  9   c . When the jog-shuttle  3  is moved to the reference position from the upward direction, the third terminal part  11   c  is separated from the third slot  9   c.    
     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  11   b  makes contact with the second slot  9   b  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  3   a  is slidably moved in the upward direction through the clearance space  3   b  formed on the base part  3   a  and the center fascia panel  1 . 
     Further, when the base part  3   a  is moved, the guide pin  7   b  is moved from the slider  7   a  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  11   c  makes contact with the third slot  9   c  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  11   c  is separated from the third slot  9   c.    
     Next, when the jog-shuttle  3  is moved to the reference position, the second slot  9   b  of the PCB  9  makes contact with the second terminal part  11   b.    
     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.
