[0011]

The above-mentioned conventional panel attaching / detaching mechanism has a problem that the mechanism is complicated, the number of parts is large, and the number of assembling steps is large. In addition, there is a disadvantage that the structure of the mechanical part is large and restricts the design of the entire device.

The present invention has been made in view of the above points, and an object of the present invention is to provide a panel attaching / detaching mechanism in which the number of components is small and an attaching / detaching operation is smoothly performed by a simple mechanism. .

[0013]

According to the present invention, there is provided a panel attaching / detaching mechanism for attaching / detaching a panel of an in-vehicle acoustic device to / from an acoustic device, from which an operation panel is detachable. Having a hook locking portion for supporting the holding member having a shape so as to be able to move in and out of the audio device main body and to be rotatable, and urging the holding member with a spring in a protruding direction and a locking direction to lock the detachable panel at its mounting position. The lever is rotatably supported by the audio equipment main body and is urged by a spring in the locking direction.

[0014]

According to the panel attaching / detaching mechanism of the present invention, when the detachable panel is detached from the main body, the holding member projects from the main body by the elastic force of the spring. In this state, when one end of the detachable panel is locked to the main body and the other end is pushed in, the holding member rotates against the elasticity of the spring, and the hook locking portion locks the detachable panel.

Further, when the detachable panel is pushed in, the holding member is pushed into the main body, the locking lever rotates against the elasticity of the spring, and the hook engaging portion locks the detachable panel at the mounting position. The acoustic device is used with the detachable panel mounted on the main body in this manner.

When the detachable panel is removed, when the locking of the locking lever is released by a release knob or the like, the holding member pushes the detachable panel by the elastic force of the spring while retaining the detachable panel. The detachable panel is held at a position away from the main body, and when it is pulled by hand, the holding member rotates against the elasticity of the spring, the latch of the detachable panel is released, and the detachable panel is removed from the main body. Can be. In this way, the detachable panel can be easily removed without dropping from the main body.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A panel attaching / detaching mechanism according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing a movable portion in a panel attaching / detaching mechanism according to an embodiment of the present invention. Reference numeral 17 shown in the figure denotes a mounting bracket, which is fastened to the main body panel 1 shown in FIGS.

The leaf spring 20 having the pressing portions 20a and 20b is fastened to the mounting member 17. The shaft 22 is the mounting bracket 1
7, the round hole of the locking lever 18 and the long hole 19b of the holding member 19 are inserted and locked by the retaining ring 23.

The locking lever 18 is rotatably supported by the shaft 22, and is pushed by the pressing portion 20 a of the leaf spring 20, and the projection at the rear end thereof is pressed against the mounting member 17. A hook locking portion 18 for locking the detachable panel is provided above and below the locking lever 18.
a, 18a are provided, and an inclined portion 18b pressed by a release knob is provided at the front center. Further, a guide groove 18c for guiding the holding member 19 is provided at the center.

The holding member 19 includes a shaft 22 and a guide groove 18.
c so as to be rotatable and slidable, and the sliding contact portion 19c
Is pressed by the pressing portion 20 b of the leaf spring 20, and the projection at the rear end is pressed against the mounting bracket 17. Further, it is urged by a tension coil spring 21 so as to protrude forward. Further, a hook locking portion 19a for locking the detachable panel is provided in front of the holding member 19. The holding member 19 can be moved in the front-rear direction by being guided by the shaft 22 and the guide groove 18c as shown in FIG. 3, but its movement range is limited by the length of the elongated hole 19b.

Next, the operation of the panel attaching / detaching mechanism will be described with reference to FIGS. 2, 4 and 5. When attaching the detachable panel 2 to the main body panel 1, first, the recess 2a at the left end of the detachable panel 2 is engaged with the projection 1a of the main panel 1 as shown in FIG. Then, when the detachable panel 2 is lightly pushed, the holding member 19 rotates against the elasticity of the leaf spring 20, and as shown in FIG. Is locked. When the detachable panel 2 is further pushed in, the locking lever 18 is pushed by the detachable panel 2 and rotates against the elasticity of the leaf spring 20 as shown in FIG. Put in. FIGS. 4C and 2A show a state in which the detachable panel 2 is mounted. As shown in FIG. 4C, the recess 2 c of the detachable panel 2 is locked by the hook locking portion 18 a of the locking lever 18. Further, as shown in FIG. 2A, the holding member 19 is retracted against the elasticity of the tension coil spring 21. In this state, the audio equipment is used.

When the detachable panel 2 is removed, FIG.
Is pressed in against the elasticity of the spring. 4 (a) to 4 (c), the illustration of the release knob 24 is omitted.

The inclined portion 18b of the locking lever 18 is pushed by the release knob 24, and the locking lever 18 rotates against the elasticity of the leaf spring 20, and the locking of the detachable panel 2 is released.
Then, the holding member 19 protrudes from the position shown in FIG. 2A to the position shown in FIG. 2B by the elasticity of the tension coil spring 21. FIG. 5A shows a state before the holding member 19 protrudes, and FIG. 5B shows a state after the holding member 19 protrudes. Since the pressing portion 20b of the leaf spring 20 is in sliding contact with the sliding portion 19c of the holding member 19, the movement of the holding member 19 is reduced. Further, the sliding contact portion 19c is inclined so that the movement of the holding member 19 is smooth.

In the state shown in FIG. 2B, the holding member 19
Is urged clockwise by a leaf spring 20 and a tension coil spring 21 to securely hold the detachable panel 2. In this state, when the detachable panel 2 is pulled by hand, the holding member 19 rotates against the elasticity of the spring, and the detachable panel 2 can be removed. In this way, the detachable panel can be easily removed without dropping from the main body.

[0025]

According to the panel attaching / detaching mechanism of the present invention, there is no possibility that the panel is accidentally dropped during the attaching / detaching operation. In addition, since the attachment / detachment operation is smooth, it gives a feeling that the product is a luxury product.

Further, the number of parts and the number of assembling steps are small, so that significant cost reduction and stable quality can be achieved.

Also, since the occupied space of the mechanism is small, it can be shared with many models, and mass production of parts becomes possible.
