Abstract

(57) [Abstract] [Purpose] To provide a panel attaching / detaching mechanism that saves space and reduces the cost in a vehicle-mounted electronic device. [Structure] The audio device body 1 has a recess 1a and an engagement recess 1b.
Is provided. A projection 2a and a lock lever 3 are rotatably supported on the operation panel 2 and are urged to rotate right by a torsion spring 4. When the detaching knob 5 is pushed from the mounted state shown in FIG. 1, the contact portion 5b is actuated by the inclined portion 5b to rotate the lock lever 3 to the left. As a result, the hook 3a is disengaged from the pull-in operation panel 2. When the knob 5 is released, the knob 5 returns to a predetermined position by the rotational biasing force of the lock lever 3.

[Problems to be solved by the device]

 However, the above-described conventional panel attaching / detaching mechanism has a large space required for the attaching / detaching mechanism, and thus has been greatly restricted in product design.

Further, the number of parts is large and the cost is high.

The present invention has been made in view of the above points, and an object thereof is to provide a panel attaching / detaching mechanism that solves the drawbacks of the conventional example, saves the space of the mechanism, and reduces the cost. It is in.

[0008]

[Means for Solving the Problems]

 The panel attaching / detaching mechanism of the present invention is a panel attaching / detaching mechanism for an in-vehicle electronic device in which an operation panel can be removed, an engaging concave portion provided in the electronic device main body, a knob provided through the panel, and By a panel provided with a lock lever linked and pivotally biased in the locking direction by the first spring member, when the panel is pushed in, the engaging recess is engaged with the lock lever to lock the panel. It is configured like this.

When the knob is urged toward the back surface of the panel by the second spring member and the knob is pushed, the lock lever is rotated and the lock is released, and the panel is moved by the second spring member. It is configured to be pushed out.

[0010]

[Action]

 According to this invention, the engaging recess provided in the electronic device main body, the knob provided through the panel, and the lock linked to the knob and pivotally biased in the locking direction by the first spring member. With a panel provided with a lever, when the panel is pushed in, the engaging recess is engaged with the lock lever to lock the panel.

Further, a second spring member is provided on the knob to urge it toward the back surface of the panel, and when the knob is pushed, the lock lever is rotated to release the lock, and the second spring member is used. The panel is pushed forward.

【Example】

 An embodiment of the panel attaching / detaching mechanism according to the present invention will be described with reference to FIGS. The same parts as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

FIG. 1 is a plan sectional view showing a first embodiment of the present invention, FIG. 2 is a plan sectional view showing a state where an operation panel is unlocked in the first embodiment, and FIG. FIG. 14 is a plan sectional view showing a state in which the lock of the operation panel is released in the second embodiment. In the figure, 1b is an engaging recess provided at the right end of the audio equipment body 1. Reference numeral 3 denotes a lock lever, which is rotatably supported by a fulcrum shaft 2c provided on the operation panel 2 and is urged to rotate counterclockwise by a torsion spring 4. 3a is a hook and 3b is an abutting portion.

Reference numeral 5 denotes a knob for taking out the operation panel 2, which is provided so as to penetrate the operation panel 2 and is supported so as to be freely pushed back. Reference numeral 5a is a tip portion, 5b is an inclined portion, 5c is a flat portion, and 5d is a flange. Reference numeral 6 denotes a tension spring, which is stretched between the flange 5d and the operation panel 2 and biases the knob 5 rearward.

The operation of the present invention configured as above will be described. In the first embodiment, as shown in FIGS. 1 and 2, when the projection 2a is engaged with the recess 1a and the operation panel 2 is pushed in, the hook 3a of the lock lever 3 is retracted, and the operation panel 2 is moved. While being attached to the audio equipment body 1, the operation panel 2 is locked by entering the engaging recess 1b provided at the right end of the audio equipment body 1. In this way, as shown in FIG. 1, the operation panel 2 is mounted on the audio equipment body 1.

When the knob 5 is pushed to remove the operation panel 2, the contact portion 3b of the lock lever 3 is rotated counterclockwise by the inclined portion 5b of the knob 5, and the hook 3a is pulled in and engaged. To cancel. Next, the operation panel 2 is pulled out.

When the knob 5 is released, the lock lever 3 is rotated clockwise by the rotational biasing force, so that the contact portion 3b pushes up the inclined portion 5a, and the knob 5 returns.

In the second embodiment, as shown in FIG. 3, the knob 5 is biased rearward by the tension spring 6, but the rotational biasing force of the lock lever 3 by the torsion spring 4 is larger. The knob 5 is normally biased forward and is in a predetermined position.

When the knob 5 is pushed to remove the operation panel 2, the engagement between the hook 3a and the engagement recess 1b is released as in the first embodiment. When the tip portion 5a of the knob 5 comes into contact with the audio equipment main body 1, the abutting portion 3b of the lock lever 3 is located on the flat portion 5c of the knob 5 and thus easily slides.

As a result, the operation panel 2 is pushed forward from the audio device body 1 by the tension spring 6.

[0021]

[Effect of device]

 Since the panel attaching / detaching mechanism according to the present invention is configured as described above, the attaching / detaching mechanism can be realized in a narrow space. Moreover, since no space is required in the audio equipment itself, the degree of freedom in product design increases.

Further, since the number of parts can be reduced, the cost can be reduced.
