Description

[Detailed description of the invention] This invention is a vehicle radio operation button mounting structure,
In particular, a push button for operating the pointer located adjacent to the radio display is incorporated into the front panel of the radio.
This invention relates to an operation button mounting structure for a vehicle radio that is improved so that the operation button can also be attached to and removed from the radio unit at the same time as the front panel is attached to and removed from the radio unit.

Vehicles are usually equipped with a vehicle radio set, that is, a car radio, either as standard equipment or as an option, and the occupants can turn the tuning knob or press the tuning button. It is possible to select a favorite station and enjoy the broadcast. A conventional example of a vehicle radio equipped with operation buttons for easily selecting a radio station is the one shown in FIG. 1, for example. This vehicle radio is equipped with a radio unit 1 containing a tuner, an amplifier and other electrical parts and circuits, a variable condenser, and a volume with their respective operating rods 4 and 5 protruding from both ends of the front. A display section 2 and a pointer 3 that can be slid horizontally along the display section 2 are installed on the front surface, and an operation button 6 for tuning is installed below the display section 2. An opening 1 on the front through which the operation button 6 is inserted
A front panel 7 having holes 11 through which the operating rods 4 and 5 are passed is attached, and operating knobs 8 and 12 are fixed to the operating rods 4 and 5, respectively. When listening to a radio broadcast, the user turns on the operating knob 12 to turn on the radio, turns the operating knob 8 or presses the operating button 6 to move the pointer 3, and simultaneously selects a station.

However, in the vehicle radio configured as described above, the front panel 7 is made of a single panel material in which a display window 9 and an opening 10 are formed, and the pointer 3 that slides left and right within the display section 2 is operated. button 6,
The display section 2 is either built into the radio unit 1 or is attached integrally with it, so normally,
Changing the operation button 6 or the like to one having a different shape or structure involves difficulty in attaching and detaching the button. However, just as different countries have established different standards for vehicles, each country often has its own standards for the external structure of vehicle radios (for example, measures against protrusions). For example, in some countries, because the operation button 6 protrudes from the radio body toward the interior of the vehicle, it may be required that the corners of the button 6 be rounded to a certain degree or more in order to protect the occupants from injury. be. In such a case, the structure of the operation button 6 must be changed in order to conform the configuration of the vehicle radio to various standards, but in the case of the above-mentioned conventional vehicle radio, the operation button 6 is not the same as the radio unit 1.
Since the radio unit 1 has an integrated structure, it is necessary to increase the number of models of the radio unit 1, which makes product management complicated and increases management man-hours.

The present invention was developed by focusing on these conventional problems, and its purpose is to configure the operating buttons of a vehicle radio separately from the radio unit and attach them to the front panel, and to The operation button can be attached to the radio unit at the same time as the panel is attached, and while the radio unit can be mass-produced as a single model, the shape of the operation button can be changed by simply changing the front panel. The objective is to reduce the manufacturing cost of radios and to simplify product management.
