Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting / demounting device for a control unit, and more particularly to a mounting / demounting device for a main body of a control unit equipped with operation switches for operating a vehicle-mounted audio device.

[0002]

[Prior art]

 In-vehicle audio equipment has tended to become higher-grade and more expensive in recent years, but this has caused a problem that the possibility of being stolen increases.

For example, Japanese Utility Model Publication No. 62-16030 discloses a configuration in which a main body of an audio device and the control unit are separately provided, and a control unit is selectively attachable to and detachable from a front panel of the main body. There is. If this is applied to the on-vehicle audio equipment, the driver can easily remove only the control unit when leaving the vehicle and take it outside the company, so even if the main body is removed from the vehicle body, it can not be used. The advantage is that it is less likely to be taken away.

[0004]

[Problems to be solved by the device]

 When the control unit is detachably attached to the main body in this way, the holding device when the control unit is attached to the main body becomes a problem. Swing-type latching devices are commonly used, but it is preferable that they fit within the smallest dimensions possible.

The present invention was devised on the basis of such knowledge, and its main purpose is to set the mounting state of the control unit to the main body portion without complicating the structure and increasing the size. It is an object of the present invention to provide a control unit attachment / detachment device that is configured to be stably supported.

[0006]

[Means for Solving the Problems]

 According to the present invention, such a purpose is to arrange the control unit between a state in which substantially the entire portion is received in the receiving portion provided on the front panel of the main body and a state in which one side of the receiving portion is popped up from the receiving portion. A control unit attachment / detachment device configured to be tiltably supported is attached to a base plate fixed to the bottom surface of the receiving section so that its free end can be freely retracted from the bottom surface of the receiving section, and is always attached. The push-out member that is elastically urged in the protruding direction and the push-out member that is pivotally attached to the push-out member so as to be able to engage with one side of the control unit are always tilted in the direction that engages with one side of the control unit. The biased holder member, the engaging claw provided on the push-out member to hold the push-out member in the position where the push-out member is recessed, the push button provided on the base plate, and the push-member pivot. Is accomplished by a swing latch swings about an axis perpendicular to, and also to that having a latch means comprising a resilient means for urging the Suingura pitch the direction of engagement with the engaging claw thing.

[0007]

[Action]

 With this configuration, the push-out member pushes out the rear surface of the control unit to realize a so-called pop-up operation, so that the operation of removing the control unit from the main body can be easily performed. Also, since both sides of the control unit are elastically supported in the popped-up state, it is possible to prevent the control unit from falling off in the protruding state. The engagement of the engaging claw and the swing latch holds the position of the push-out member in a state where the control unit is received in the receiving portion.

【Example】

 Hereinafter, a configuration of the present invention will be described in detail with reference to specific embodiments shown in the accompanying drawings.

FIG. 1 is a perspective view showing a front portion of, for example, a CD deck as an on-vehicle audio equipment to which the present invention is applied, showing a state in which a control unit 1 is removed from a front panel 2 of a main body. As shown in the figure, the control unit 1 is in the shape of a horizontally long plate, and is provided with operation switches and indicators on the front surface thereof. The front unit of the CD deck mounted on the instrument panel of the vehicle. It is adapted to be received by the receiving portion 3 formed on the panel 2.

As shown in FIG. 2 and FIG. 3 as well, recesses 4 and 5 that are open outward and on the back side are provided on both sides in the longitudinal direction of the control unit 1. An extruding member 6 is provided on one side of the bottom surface 3a of the receiving portion 3 in the longitudinal direction.

The push-out member 6 is pivotally attached to the base plate 7 fixed to the back surface of the front panel 2 via a pin shaft 8 and is substantially in the same plane as the bottom surface 3 a of the receiving portion 3 (see FIG. 2). (See FIG. 3) and a position (see FIG. 3) in which the free end portion located on one corner side of the receiving portion 3 projects from the bottom surface 3a (see FIG. 3). A torsion coil spring 9 is wound around the pin shaft 8 to constantly elastically urge the pushing member 6 in the protruding direction.

The push-out member 6 has a triangular shape in a plan view, and a holder member 11 is pivotally attached to a top of the free end facing the inside of the main body through a pin shaft 10. A torsion coil spring 12 is also wound around the pin shaft 10 of the holder member 11, and the holder member 11 is constantly elastically urged toward the center of the receiving portion 3. The free end of the holder member 11 is formed with a hook portion 13 which can be engaged with the recess 4 on one side of the control unit 1. The recess 4 on one side and the hook portion 13 constitute a first engaging means.

A stopper 14 for contacting the rear surface of the substrate 7 and defining the protruding position of the pushing member 6 is provided in the vicinity of the pivot portion of the holder member 11 of the pushing member 6.

On the other corner side in the longitudinal direction of the receiving portion 3, a set of protrusions 15 is provided so as to be substantially parallel to the bottom surface 3 a of the receiving portion 3. The projection 15 can be inserted into the recess 5 on the other side of the control unit 1. The recess 5 on the other side and the set of protrusions 15 form second engaging means.

As shown in FIGS. 4 and 5, at a position below the pushing member 6 on the substrate 7, the tilting shaft of the pushing member 6, that is, a swing about an axis orthogonal to the axis of the pin shaft 8 is swung. As can be seen, a triangular swing latch 16 is pivoted with its first apex. A hook 18 that can be engaged with a claw 17 provided on the lower surface of the pushing member 6 is formed on the second top portion of the swing latch 16. A torsion coil spring 19 for constantly elastically urging the swing latch 16 in a direction to engage the hook 18 with the claw 17 of the pushing member 6 is wound around the swing shaft 20 of the swing latch 16.

A push button 21 is provided on the front surface of the substrate 7 so as to be capable of projecting and retracting from the bottom surface 3 a of the receiving portion 3. The push-in direction end portion 21a of the push button 21 is linked to the third top portion of the swing latch 16.

The control unit 1 is provided with an operation rod 22 penetrating the front and back of the control unit 1 at a position where it can contact the head of the push button 21 when mounted on the front panel 2. With the control unit 1 mounted, by pushing the operation rod 22 in the direction shown by the arrow A in FIG. 4, the head of the push button 21 is pushed in, and the swinging force is resisted against the biasing force of the torsion coil spring 19. Since the latch 16 rotates clockwise as seen in FIG. 4, the engagement between the claw 17 and the hook 18 is released.

In the attachment / detachment device of the control unit 1 according to the present invention, the control unit 1 is received in the receiving portion 3 in the mounted state, one side of which is shown in FIG. It is in the engaged state. At this time, the push-out member 6 is in a state of being retracted from the bottom surface 3a of the receiving portion 3, and the claw 17 of the push-out member 6 and the hook 18 of the swing latch 16 are engaged with each other to hold the retracted position of the push-out member 6. ing. In this mounted state, the control unit 1 is electrically connected to the main body via the connection terminals (not shown) provided on both the control unit 1 and the bottom surface 3a of the receiving portion 3, and the control unit is controlled. The main body can be controlled by various operation switches on the front of the unit 1.

When the control unit 1 is removed, by pushing the tip of the operation rod 22 exposed on the front surface of the control unit 1, the engagement state between the claw 17 and the hook 18 is released as described above. Therefore, the pushing member 6 projects due to the biasing force of the torsion coil spring 9, and one side in the longitudinal direction of the control unit 1 pops up from the receiving portion 3 as shown in FIG.

At this time, the control unit 1 tilts with the engaging portion between the depression 5 and the projection 15 on the other side as a fulcrum, and the pushing member 6 is displaced from the center of the receiving portion 3 in the longitudinal direction to the outside. Since it tilts as a fulcrum, the locus on one side of the control unit 1 and the locus of the free end of the pushing member 6 do not match, but the holder member 11 engaged with the recess 4 on one side of the control unit 1 pushes the pushing member. 6, the holder member 11 is elastically urged in the direction in which the hook portion 13 bites into the recess 4, so that the length of the control unit 1 is long even in the protruding state shown in FIG. The engaged state of both side portions in the direction is suitably maintained.

From this state, when one side of the control unit 1 is pulled in the direction of arrow C in FIG. 3 with the engaging portion between the depression 5 and the protrusion 15 as a fulcrum, the hook portion 13 has an inclined surface and the depression 4 on one side. Since the holder member 11 tilts in the direction of arrow E, the engagement of the same portion is easily released. Alternatively, the control unit 1 is moved in the direction of arrow B in FIG. 3 against the biasing force of the torsion coil spring 12 with respect to the holder member 11 to release the engagement state between the depression 5 on the other side and the projection 15 first. In addition, the hook portion 13 of the holder member 11 may be detached from the recess 4 on one side.

When mounting the control unit 1, contrary to the above, by inserting the hook portion 13 of the holder member 11 into the recess 4 on one side and moving the control unit 1 in the direction of arrow B, The depression 5 on the other side and the projection 15 can be engaged with each other, and by further pushing in the control unit 1, the pushing member 6 is also pushed in in the recess direction. When the retracted position shown in FIG. 2 is reached, the hook 18 of the swing latch 16 rides on the tapered surface 17a of the claw 17 of the pushing member 6 and they engage with each other, and the control unit 1 is received in the receiving portion 3. It is held in the installed state. Alternatively, first, the recess 5 on the other side and the protrusion 15 are engaged with each other, and then, regardless of the protruding state or the retracted state of the pushing member 6, if one side of the control unit 1 is pushed in the direction of the arrow D, the holder member 11 Tilts in the direction of arrow E, and the engagement between the recess 4 on one side and the hook portion 13 is realized.
