Front panel driving device

Abstract

A front panel driving apparatus for a car audio system comprises a main chassis, a slider base fitted inside the main chassis, and a slider. A plurality of roller structures are provided for promoting a more stable motion of the slider. The roller structures are formed between the slider base and the slider. A front panel is opened or closed by translating vertically when the slider moves back and forth. A lower end portion of the front panel is hinged upon a front end portion the slider. Projections that are protruded from both upper ends of the front panel are mounted inside generally vertical tracks of a front frame that is attached to a front of the main chassis.

Description

technical field [0001] The present invention relates to a front panel driving device of a car audio system including a display portion occupying a large part of the front surface of the car audio system. More particularly, the present invention relates to a front panel driving device which contributes to smoother and more stable operation of the front panel when opening / closing. Background technique [0002] People pay more and more attention to the car entertainment system, especially the car audio system as one of the basic configurations of the car. Various types of media players are now installed in cars. [0003] For example, US Patent No. 6,398,168 discloses a pull-down system in which a car audio system includes a front display panel that translates vertically when recording media is inserted or ejected. [0004] FIG. 1 is a side view of a front panel driving device for a car audio system according to the related art. FIG. 2 is a plan view of a part of a front pane...

AI Technical Summary

Problems solved by technology

This vibration eventually shakes the car stereo front panel connected to the front part of the slider 25

And this vibration of the front panel may also damage other parts or cause mechanical failure

This problem will occur more frequently under difficult driving conditions, such as on a bumpy road, and most drives are excited by the vibration of the front panel

[0014] However, reducing the space between the slider 25 and the main chassis to prevent vibration of the front panel is not a good idea as it will make it more difficult to assemble the slider and front panel

Also, if this is done, the slide 25 could fall into the main chassis
