Description

[Detailed Description of the Invention] The present invention relates to a panel lighting mechanism mounted on the front of a car radio, car stereo, etc.

In conventional car radios, car stereos, etc., the center dial A is illuminated, as shown in Figure 1, but the knobs B located on the left and right of it are not illuminated. . Therefore, when operating these knobs B at night, it is difficult to confirm the position of the knobs B due to the darkness inside the car, and you have to grope to find them.Furthermore, the functions of the knobs B are written on the panel. However, it was too dark to read, so I had to rely on my memory to operate it.

In order to eliminate these drawbacks, conventionally the panel section attached to the front of the playback device was made of a light-transmitting material, and the light emitter placed at the rear of the panel was made to emit light. There were some that were designed to improve the visibility of the character display on the panel and the operability of the knobs.

However, the light emitting body placed in the panel part,
Because it is formed to be directly embedded in the acrylic panel section, or because the luminous body is constructed by integrally laminating a luminescent layer and an electrode layer on a metal electrode, the panel section that emits light is The problem was that the texture was poor and the light emitting body was expensive. In addition, the means for supplying power to the light emitter is
Since the panel part is assembled after directly connecting the light emitter in the playback device, processing accuracy is required for positioning the light emitter and the panel part, making assembly work difficult. There was a problem.

The present invention aims to solve the above-mentioned drawbacks, and includes a dial part protruding from the front of the playback device, rotary shaft parts such as variable resistors protruding from the left and right sides of this dial part, and a dial part protruding from the front of the playback device. and a panel frame that is attached to the front of the playback device and has a frame and a window hole that fits into the rotating shaft, and a light-transmissive panel that has a hole into which the rotating shaft is inserted. mated,
Furthermore, a plate made of a light-transmitting member is fitted into the frame portion, a contact piece is formed on the side surface of the dial portion to be a recess in a horizontal direction from the side surface, and a light emitting element is embedded in the panel portion. In addition, by providing a terminal on the window hole side that can freely go in and out of the window hole and contact the contact piece, it not only improves visibility and operability at night and in dark places, but also improves the luminescence of the panel part. The purpose is to provide a panel lighting mechanism for car stereos, etc., which has a soft feel, is inexpensive, and is easy to assemble.

Hereinafter, the present invention will be explained based on the drawings. FIG. 2 is an exploded perspective view of the panel lighting function according to the present invention, and FIG. 3 is an assembled plan view thereof. Reference numeral 1 denotes a playback device such as a car radio or a car stereo, and a rectangular parallelepiped dial portion 2 is protruded from the center of the front surface thereof. Number 3 is the dial, and this part is illuminated. In addition, on the left and right sides of the dial part 2,
A sliding/show type contact piece 4 is provided horizontally in a concave portion from the side surface. This contact piece 4 is connected to a power source. Above dial part 2

Reference numeral 13 denotes a panel attached to the front surface of the reproduction device 1, and this panel 13 is made of a light-transmitting member such as glass, acrylic, or polycarbonate. Therefore, it may be transparent or translucent. In the center, there is a window hole 1 in which the dial part 2 fits.
4 is formed. In addition, the left and right panel portions 13
Holes 15a and 15b into which the male screw portions 6 of the variable resistors 7 and 8 are inserted are formed in holes 15a and 13b, and characters 16 such as function names and company names are displayed. Furthermore, lamps are provided on the panel portions 13a and 13b.
Light emitting elements 17a and 17b such as LEDs are buried. In addition, the window holes 14 of the panel parts 13a and 13b
On the side, there are terminals 18a that can be freely contacted with the contact piece 4,
18b is provided in the window hole 14 so as to be freely accessible.
It is urged toward the window hole 14 side by a spring.

Therefore, the female screws 11 are screwed into the male screw portions 6 of the variable resistors 7 and 8, and the male screw portions 6 are connected to the panel 1.
After inserting into the holes 15a and 15b of No. 3, the female screw 12
are screwed together, and the panel 13 is fixed in a clamped state using both screws 11 and 12. As a result, the light emitting element 17
a, 17b are connected to the power source via terminals 18a, 18b→contact piece→. After that, the knobs 9 and 10 are fitted onto the rotating shaft 5. And the light emitting element 17a,
When 17b is made to emit light, the light is emitted from panel section 13.
The knobs 9 and 10 are illuminated by diffused reflection inside the knobs a and 13b, and their positions can be confirmed. Also, character 1
The characters can be read by the light that passes through 6.

FIG. 4 is an exploded perspective view showing another embodiment of the panel illumination mechanism. In the drawing, 19 is playback device 1
A window hole 14 into which the dial portion 2 fits is formed in the center of the panel frame. In addition, rectangular frame portions 2 are provided on the left and right sides of the window hole 14.

The panels 21a and 21 are made of a light-transmitting material such as glass, acrylic, or polycarbonate.
is fitted thereon, and a plate 22 made of a light-transmitting member is pasted thereon. Characters 16 are displayed on the plate 22 by printing or cutting. In addition, the overlapped frame portions 20a, 20
Holes 23 into which male threaded portions 6 of variable resistors 7 and 8 are inserted are formed in the bottom plate b, panels 21a and 21b, and plate 22. The above frame part 20
A, 20b are provided with light emitting elements 17a, 17b and terminals 18a, 18b. Note that portions of the panels 21a and 21b corresponding to the light emitting elements 17a and 17b are cut out. In addition, playback device 1
The attachment to is the same as in the previous embodiment.

As mentioned above, the present invention has a dial part protruding from the front of the playback device, a rotary shaft part such as a variable resistor, etc. protruding from the left and right sides of this dial part, and a rotary shaft part such as a variable resistor that is fitted onto the dial part and the rotary shaft part. a panel frame that is attached to the front of the reproduction device and has a window hole and a frame portion, and a light-transmissive panel portion that has a hole into which the rotating shaft portion is inserted is fitted into the frame portion; A plate made of a light-transmitting member is fitted into the frame portion, a contact piece is formed on the side surface of the dial portion to be a concave portion in a horizontal direction from the side surface, and a light emitting element is embedded in the panel portion. On the side of the window hole, a terminal is provided which can move in and out of the window hole and can come into contact with the contact piece.

Therefore, visibility and operability at night or in a dark place can be improved, and the light emitted from the panel becomes indirect, resulting in a softer texture. Further, the light emitting body can be used at a lower cost than conventional light emitting bodies, and the electrical connection to the light emitting body and the assembly work of the panel section are simplified.
