[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle audio device.

[0002]

[Prior art]

 As shown in FIG. 4, an operating portion of a conventional vehicle audio device has audio electronic components mounted on both sides of a board 50, and one side 50a of the board 50 has tact switch 51 together with audio electronic components. And a lamp 52. The other surface 50b of the substrate 50 is provided with a connector 53 together with audio electronic components. The substrate 50 is housed in a casing (not shown) and integrated as an operating portion of an in-vehicle audio device, and is fastened to an opening of a vehicle panel.

[0003]

[Problems to be solved by the device]

 However, the conventional vehicle audio equipment mounts the audio electronic components on both sides of the board 50, which complicates the production process, and the tact switch 51 is a surface mount type in which the back side is not exposed. Since this is necessary, it may lead to higher costs. Furthermore, because the panel is not detachably attached, it was necessary to take additional measures to prevent expensive audio equipment from being stolen when the user leaves the vehicle. Therefore, the present invention has been made in view of the above-mentioned circumstances, and a substrate for electronic components and the like is provided in a casing in which an operating portion of an audio device is integrated, so that a compact structure can be achieved and the attachment / detachment can be reliably performed. It is possible to provide an in-vehicle audio device that eliminates the conventional drawbacks.

[0004]

[Means for Solving the Problems]

 The present invention includes an operation unit, a circuit board on which at least these electronic components are mounted, and a detachable unit main body equipped with a connector for connecting to the main unit, and a nose fixed to the panel section of a car on which the main unit is mounted. It is characterized in that a detachable hinge part and a locking means are provided between the piece and the piece. Also, the circuit boards on which electronic components were mounted consisted of multiple sheets, which were placed parallel to each other, and the electronic components except the connector were mounted on only one side of each. Further, the plurality of circuit boards are integrally mounted on a common mounting plate. Further, a lamp was attached to the electronic component mounting surface of at least one of the circuit boards, and the attachment plate was a light-transmitting transparent plate. Further, a mounting pin protruding type switch is attached to the electronic component mounting surface of at least one of the circuit boards.

[0005]

[Action]

 The main body of the detachable part is detachably attached to the panel inside the vehicle by the hinge part and the locking means. If a plurality of circuit boards in the attachment / detachment section are used and a single-sided printed circuit board is used and electronic components are mounted on only one side, the process of assembling electronic components is simple and easy. Moreover, if these plural circuit boards are integrally attached to a common single mounting plate, the circuit board can be made compact. Further, if the mounting plate is a translucent plate, the operating part can be illuminated by the lamp mounted on the circuit board. If a switch with a mounting pin protruding type is attached to the circuit board, the attachment / detachment section will be cheaper.
