ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an on-vehicle electronic device assembly to be installed in a vehicle.
2. Description of the Related Art
Conventionally, an electronic device such as an audio device, a communication device, a navigation device, or a like device is installed into a mounting space such as a 1DIN space, a 2DIN space, or a like space formed in an instrument panel of a vehicle.
In this case, the housing of an electronic device is electrically connected to a vehicle body serving as ground so as to shield electronic components contained in the housing against noise, static electricity, and the like. To establish this grounding, when the electronic device is installed into the mounting space, a fixing portion of the housing is brought in contact with a metallic portion of a vehicle body and fixed onto the vehicle body with bolts.
Thus, the conventional electronic device cannot be removed from a vehicle for independent use.
SUMMARY OF THE INVENTION
An object of the present invention is to solve the above-mentioned problem in the conventional on-vehicle electronic device assembly and to provide an on-vehicle electronic device assembly allowing the housing of an electronic device to be electrically connected to a vehicle body serving as ground so as to shield electronic components contained in the housing as well as allowing the electronic device to be removed from the vehicle for independent use.
Another object of the present invention is to provide an on-vehicle electronic device assembly enabling a CD player to be used as an electronic device thereof and capable of preventing a disc slipping off a user's hand, when placing or removing the disc on or from the CD player, from entering far into the interior of the CD player.
According to the present invention, an on-vehicle electronic device assembly includes a mount frame fixed on a metallic portion of a vehicle body, a carriable unit disposed in the mount frame such that it can be removed from the mount frame, and urging means made of metal and mounted on the mount frame for urging the carriable unit in a direction of moving the carriable unit away from the mount frame.
The carriable unit includes a carrier case having a grounding metal piece insertion hole formed therein in a position corresponding to the urging means, a metallic chassis disposed in the carrier case so as to shield electronic components, and a grounding metal piece loosely fitted into the grounding metal piece insertion hole for electrically connecting the metallic chassis and the urging means.
In this case, when the carriable unit is pressed into the mount frame against an urging force exerted by the urging means, the grounding metal piece electrically connects the metallic chassis to the urging means. As a result, the metallic chassis is electrically connected to a vehicle body serving as ground to thereby shield the electronic components contained in the carriable unit against noise, static electricity, and the like.
Also, when the carriable unit is drawn out from the mount frame, the metallic chassis is electrically disconnected from a vehicle body serving as ground.
Thus, not only is the grounding effect improved, but also the carriable unit removed from the mount frame can be connected to a household power unit and used outside a vehicle. Also, a resin portion of the carrier case is not susceptible to formation of scratches, thereby maintaining design appearance thereof.
Since the grounding metal piece is loosely fitted into the grounding metal piece insertion hole, leaving a clearance therearound, any error of manufacture of the mount frame, carriable unit, or like component is absorbed by the clearance. Accordingly, the metallic chassis and a vehicle body serving as ground can be electrically connected together in a removable manner.
An on-vehicle electronic device assembly according to another aspect of the present invention includes an outer frame, a CD player disposed in the outer frame such that the CD player can be advanced and retracted, and disc entry prevention means for preventing a disc from entering far into the interior of the CD player through a clearance formed between the outer frame and the CD player when the CD player is situated at an advanced position.
When the CD player is drawn out to the advanced position thereof, a clearance is formed between the outer frame and the CD player; however, the disc entry prevention means prevents a disc from entering far into the interior of the CD player through the clearance.
Accordingly, even when a disc slips off a user's hand when the user attempts to place the disc on the CD player or to remove the disc from the CD player, the disc is prevented from entering far into the interior of the CD player through the above-mentioned clearance.
Also, when an on-vehicle electronic device cannot be disposed horizontally in a center console of a vehicle, the disc entry prevention means prevents a disc from entering far into the interior of the CD player through the clearance formed between the outer frame and the CD player and thus from being scratched.
