Abstract

(57) [Abstract] [Purpose] To provide a panel attachment / detachment mechanism that can be removed smoothly from an on-vehicle electronic device and that can use a wide panel surface. [Structure] A recess 1b for mounting a panel 2 is provided on an escutcheon 1a provided on the front surface of a main body 1. An eject knob 3 is provided at the right end of the escutcheon 1a. A slider 4 provided with the eject knob 3 is supported by the right side surface of the main body 1 so as to be freely pushed back, and is biased toward the panel 2 by a spring 6. Further, a lock lever 7 which is actuated by an actuating portion 4b of the slider 4 to release the lock of the panel 2 when the eject knob 3 is pushed is rotatably provided. The panel 2 mounted on the main body 1 can be removed by pushing the eject knob 3 to disengage the first engaging recess 2b from the hook 7b and pulling out the right end portion of the panel 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel attaching / detaching mechanism in an electronic device.

[0002]

[Prior art]

 Conventionally, in a vehicle-mounted audio device whose front panel is detachably configured, as shown in FIGS. 4 to 6, a recess 11b is provided in a main body panel 11a of a main body 11 of the audio device, and left and right sides of the recess 11b are provided. Engaging recesses 11c and 11d were provided in the section.

Further, in the panel 12 fitted in the recess 11b, operation knobs, a display unit and the like are arranged at positions other than the hole 12b for inserting the cassette tape.

Thus, when the panel 12 is attached to the main body panel 11a, the protrusion 12a provided on the left side surface of the panel 12 is fitted into the concave portion 11c, and then the right end is pushed toward the main body panel 11a side. The lock claw 14 provided on the right side of the device contacts the corner of the main body panel 11a, enters the panel 12, and protrudes when facing the recess 11d to lock the panel 12.

Further, when removing the panel 12, the eject knob 13 provided on the panel 12 is pushed to cause the lock claw 14 to enter the panel 12, and the panel 12 is removed in the reverse order of the above-mentioned mounting. ..

[Problems to be solved by the device]

 However, the above-mentioned conventional panel attachment / detachment mechanism is built into the panel on which the eject knob is attached / detached. When the eject knob is pressed, the lock is released, but with this, the panel is pushed in and the operation is contrary to removing it. Therefore, it was not possible to remove the panel smoothly.

Further, since the eject knob is inside the panel, the area for disposing other knobs, the display portion, etc. is reduced, which is a design limitation.

The present invention has been made in view of the above points, and an object thereof is to solve a drawback of the conventional example, to provide a panel attaching / detaching mechanism which can be smoothly detached and can use a wide panel surface. It is in the place of providing.

[0009]

[Means for Solving the Problems]

 The panel attaching / detaching mechanism of the present invention is an electronic device in which a panel is detachably provided in a front concave portion of a main body, and a slider supported on one side of the main body so as to be pushed back and a slider attached to the slider. An eject knob provided on the front surface, a lock lever supported by the main body so as to rotate in a direction in which when the eject knob is pushed, the slider is actuated by the slider and the engagement with the panel is released, and the lock lever. A first engaging recess provided near one side of the panel so as to engage with the second engaging recess and a second engaging recess protruding from the other side of the panel and provided in the front recess. With the fitting projection, the eject knob is pushed to release the engagement between the lock lever and the panel, and the panel is removed.

[0010]

[Action]

 According to this invention, since the eject knob is provided on the main body side, it can be easily removed without affecting the removal of the removable panel.

[0011]

【Example】

 An embodiment of the panel attaching / detaching mechanism according to the present invention will be described with reference to FIGS.

In the figure, reference numeral 1 is a main body of a vehicle-mounted audio device having a front panel detachable, and 1 a is an escutcheon provided on the front surface of the main body 1. 1b is a recess surrounded by the escutcheon 1a, and the panel is attached thereto. Reference numeral 1c is a second engaging recess provided on the inner left side of the escutcheon 1a, with which the projection of the panel engages. 1d is a hole for the eject knob 3 provided in the escutcheon 1a.

Reference numeral 2 denotes a panel detachably provided in the recess 1b, 2a denotes a projection provided on the left side of the panel 2 so as to engage with the second engagement recess 1c of the escutcheon 1a, and 2b engages with the hook 7b. The first engaging concave portion 2c is provided near the right side portion of the panel 2 so as to fit together, and 2c is a side wall forming the first engaging concave portion 2b.

Reference numeral 4 denotes a slider that is supported by the two bosses 5 that are attached to the eject knob 3 and that are erected on the main body so as to be pushed back to the right side of the main body 1, and 4a is a long hole through which the two bosses 5 are inserted. 4b is an operating portion for operating the lock lever, and 6 is a spring for urging the slider 4 toward the panel 2.

Reference numeral 7 is a lock lever that is actuated by the slider 4 and rotates about the fulcrum boss 8. Reference numeral 7a is an upwardly inclined portion that is actuated by sliding contact with the actuating portion 4b. 7b is the first engagement of the panel 2. A hook that engages with the recess 2b and locks. 7c is an inclined portion of the hook 7b.

The attaching / detaching operation and action of the panel attaching / detaching mechanism of the present invention configured as above will be described.

When the panel 2 is mounted on the main body 1, the protrusion 2a provided on the left side of the panel 2 is fitted into the second engaging recess 1c provided in the inner recess 1b of the escutcheon 1a, and then on the right side of the panel 2. When the portion is pushed toward the main body 1, the side wall 2c of the panel 2 contacts the inclined portion 7c provided on the hook 7b of the lock lever 7, and the lock lever is rotated counterclockwise. When the side wall 2c of the panel 2 passes the hook 7b, the lock lever 7, which is urged to rotate clockwise by a spring (not shown), rotates clockwise, and the hook 7b engages with the first engaging recess 2b. Then lock panel 2.

To remove the panel 2 from the main body 1, the eject knob 3 is pushed. As a result, the operating portion 4b of the slider 4 slides on the inclined portion 7a of the lock lever 7 to rotate the lock lever 7 counterclockwise. Therefore, the hook 7b and the first engaging recess 2b of the panel 2 are disengaged, and the panel 2 can be smoothly removed in the reverse order of the above-mentioned mounting. When the eject knob 3 is released, it is returned to a predetermined position where the boss 5 and the edge of the long hole 4a are in contact with each other, because the eject knob 3 is urged toward the panel 2 by the spring 6.

[0019]

[Effect of the device]

 Since the panel attaching / detaching mechanism according to the present invention is configured as described above, no force is applied to the panel even when the eject knob is pressed, so that the panel can be removed smoothly.

Further, since the panel surface can be used freely without being affected by the eject knob, it is possible to design freely.

Moreover, it has excellent features such as a simple structure and easy implementation because it can be constructed at low cost.
