Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted device such as a disk player and a tape player mounted on an automobile, and more particularly to a vehicle-mounted device in which an operation unit is detachably attached to a device body. Regarding the operation device.

[0002]

2. Description of the Related Art In-vehicle devices such as disk players and tape players, which are fixedly mounted in vehicles such as automobiles, have been increasing the number of automobile crimes aimed at these types of in-vehicle devices. Therefore, it is known that, for example, by adopting a structure that makes it possible to easily attach and detach the device body, the user can remove the device body from the car and store it in a safe place when the user is unwary and away from the car for a long time. There is. However, no matter how simple the device body is, it is not so easy to attach and detach the device body, and it is not easy to transport the device body having a corresponding size and weight.

Therefore, as disclosed in Japanese Utility Model Laid-Open No. 4-132684, only an operation unit called a nose piece has been made detachable, and the equipment body to which the operation unit is attached is fixed inside an automobile. An in-vehicle device to be installed has been proposed and is already in practical use. In other words, if the operation unit is detachable, it is not possible to operate the device body with this operation unit removed, so there is a low possibility that the device body inside the vehicle will be stolen in the absence of the operation unit. If it is only, there is an advantage that it can be easily attached and detached and transported.

The appearance color of the operation unit of the vehicle-mounted device and the body of the device has not been painted so far because it depends only on the molding color, but recently, the vehicle-mounted device is also unique. Since various appearance colors have been desired, for example, an attempt has been made to paint the front and side surfaces of the operation unit to desired colors.

[0005]

As described above, it has been attempted to coat a detachable operation unit with a desired color to enhance the design. However, in this type of vehicle-mounted device, Not only the front and side surfaces of the operation unit, but also the back surface and the nose mounting surface of the device body (the surface on which the operation unit is mounted) will be exposed to the outside.
If you really want to improve the design, paint not only on the operation unit but also on the exposed surface of the device body (for example, paint of the same color)
Is desirable. However, if you actually paint the back surface of the operation unit or the nose mounting surface of the device body, when the operation unit is not removed, the two surfaces that are in close contact with each other will bite the paint due to heat, and The inconvenience arises that it becomes easy to peel off partially.

In addition, an operating unit for an in-vehicle device of this type is usually provided with an engaging recess at one end thereof, which engages with a hooking protrusion on the device body side and serves as a rotation fulcrum at the time of attachment / detachment. The other end is provided with a lock groove that can hold the mounted state when it is locked by the claw on the device body side, and the connector part connected to the connector terminal on the device body side is provided in the center part. When mounting the operation unit on the device body,
After inserting the hooking protrusion into the engaging recess, the operation unit is rotated toward the nose mounting surface of the device body, and the rear surface of the operation unit is pressed against the nose mounting surface, whereby the connector portion is While being elastically contacted with the connector terminal, a locked state in which the lock groove is locked by the claw portion can be obtained. Further, as described above, in the configuration in which the elastic force is applied from the connector terminal on the device body side to the central portion of the mounted operation unit, the central portion of the operation unit that has been used for a long time is slightly swelled toward you. The warp (plastic deformation) that occurs is likely to occur. However, in the conventional operation unit having such a warp, the lock groove is locked to the claw portion when the operation unit is mounted on the main body of the device by a rotating operation with the engaging recess provided on one end side as a fulcrum. The other end abuts on the nose mounting surface before being locked, and the position is likely to be regulated. In that case, the user cannot lock the operation unit by the normal mounting method. You have to forcibly bend the operation unit by pushing firmly on, so that it takes time to install it,
It is easy to damage the operation unit itself.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a small protrusion is provided on the exposed surface of the operation unit and the device body so that the back surface of the operation unit in a mounted state makes point contact with the nose mounting surface of the device body. Even if the paint is applied, the paint does not bite due to heat. Also, by ensuring a clearance for the height dimension of the small projection between the end of the operating unit in the mounted state on the lock mechanism side and the nose mounting surface of the device body, the central part of the operating unit is Even if a bulging warp occurs, the operation unit at the time of mounting is easily locked to the device body without being restricted in position by the nose mounting surface.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In the operating device for an on-vehicle device according to the present invention, the operating unit is detachably attached to the device body fixedly installed in the vehicle, and one end of the operating unit is connected to the device body. For mounting on a vehicle, an engaging portion serving as a rotation fulcrum at the time of attachment / detachment is provided, and at the other end of the operation unit, a locked portion that can hold a mounted state when locked to the device body is provided. In a device operating device, a mounting surface (nose mounting surface) of the device body facing the operating unit in a mounted state
Then, a small projection having a minute height is provided on at least one of the back surfaces of the operation unit facing the mounting surface. In addition, it is preferable that a plurality of the small protrusions are scattered at appropriate places.

If such a structure is adopted, the back surface of the operation unit in the mounted state can be brought into point contact with the nose mounting surface of the main body of the device, rather than surface contact, so that the mounting surface and the back surface can be painted. Even if it is applied, the coating does not bite due to heat, and therefore, the exposed surfaces of the operation unit and the device main body can be applied with the same color, and the designability can be significantly improved.

If the small protrusion is provided on the side closer to the engaging portion than the engaged portion in the state where the operation unit is attached to the device body, the lock mechanism side of the operation unit in the attached state. It is possible to secure a clearance corresponding to the height dimension of the small protrusion between the end portion (on the locked portion side) and the nose mounting surface of the device body. Therefore, even if the operation unit that has been used for a long period of time has a warp such that the central portion bulges, the operation unit when mounted can make an overstroke toward the nose attachment surface side by utilizing the clearance. Therefore, the position of the operation unit is not restricted by the nose mounting surface when it is mounted, and the locked state with the device body can be easily obtained without applying excessive force.

A biasing member (not shown) or the like for pushing out from inside a is provided. Further, the inner bottom surface located in the recess 3a of the decorative portion 3 is a nose attachment surface 9 facing the back surface 4b of the operation unit 4, and this nose attachment surface 9 is located on the right side of the figure from the center. A plurality of convex portions 9a having a spherical shape with a tapered tip and a small height are formed integrally or separately at a plurality of locations. In this embodiment, the exposed surface of the device body 1 (the surface of the decorative portion 3 and the nose mounting surface 9) is coated with a metallic color.

On the other hand, the front surface of the operation unit 4 is the operation surface 4a.
The operation surface 4a is provided with various operation buttons (not shown), a liquid crystal display panel, and the like, and a cassette insertion port 10 is opened at the upper center. Also,
At the right end of the operation unit 4 in the drawing, an engaging recess 1 that engages with the hooking protrusion 6 of the device body 1 and serves as a rotation fulcrum when attaching and detaching.
1 is provided, and a lock groove 12 is provided at the left end portion in the drawing so that the mounting state can be held when the lock claw 7 of the device body 1 is engaged. A connector portion (not shown) for connecting to the connector portion of the device body 1 is provided at the lower center of the operation unit 4. The exposed surface of the operation unit 4 is also painted in the same color as the exposed surface of the device body 1.

When mounting such an operation unit 4 on the decorative portion 3 of the device body 1, first, the hooking projection 6 of the device body 1 is inserted into the engagement recess 11 to engage them. The operating unit 4 is rotated toward the nose mounting surface 9 of the device body 1 with this engaging point as a fulcrum. That is, by rotating the operation unit 4 in the direction of arrow A in FIG.
The device body 1 is inserted into the recess 3a. Then, when the back surface 4b of the operation unit 4 is rotated until it becomes substantially parallel to the nose mounting surface 9, the back surface 4b abuts on the lock claw 7 of the device body 1 in the vicinity of the lock groove 12, so that the lock claw 7 is aforesaid. The arrow B in FIG. 2 resists the biasing force of the spring member.
When the operation unit 4 is further rotated in the direction of arrow A, the lock claw 7 separates from the back surface 4b and enters the lock groove 12 as shown in FIG. Therefore, in this state, the lock claw 7 locks the lock groove 12 by the urging force of the spring member, so that the operation unit 4 is mounted and held in the recess 3a of the device body 1 without falling off. , Will be locked. When the mounting of the operation unit 4 is completed in this way, the connector portion of the operation unit 4 is in a state of elastically contacting the connector terminal of the device body 1, so that power supply and signal transmission are performed between them. It will be. Further, since the protrusions 9a are scattered on the right side of the figure from the center of the nose attachment surface 9, when the operation unit 4 is completely attached, the rear surface 4b and the nose attachment surface 9 have the protrusions. It opposes via the clearance C corresponding to the height dimension of the portion 9a.

When the operation unit 4 in the mounted state is taken out from the device main body 1, if the lock release button 8 is pushed by a predetermined amount with a finger, the lock claw 7 is rotationally driven in a direction to be separated from the lock groove 12. Therefore, the locked state is released, and therefore the recess 3a is formed by the urging force of the urging member.
The operation unit 4 can be easily removed from the device body 1 by releasing the engagement between the engagement recess 11 and the latching projection 6 while holding the operation unit 4 to be pushed out from the inside by hand.

As described above, the vehicle-mounted audio equipment according to the present embodiment is provided with high designability by coating the exposed surfaces of the equipment body 1 and the operation unit 4 with the same metallic color. Conventionally, such painting is
The coating on the nose mounting surface 9 and the back surface 4b is not adopted because it is apt to bite due to heat, but in the present embodiment, as described above, the nose mounting surface 9 is dotted with the convex portions 9a having a spherical tip. Therefore, when the operation unit 4 is mounted, the back surface 4b and the nose mounting surface 9 face each other in a point contact state. Therefore, both surfaces 4b and 9 are painted. However, the coating does not bite due to heat.

Further, in the present embodiment, as described above, on the right side of the figure from the center of the nose mounting surface 9, in other words, on the side closer to the engaging recess 11 than the lock groove 12 with the operation unit 4 mounted, Since all the projections 9a are located, the left side of the operation unit 4 in the mounted state in the drawing (the lock groove 1
A clearance C corresponding to the height dimension of the convex portion 9a is secured between the end (on the second side) and the nose mounting surface 9. Therefore, even if the operation unit 4 that has been used for a long period of time undergoes a warp (plastic deformation) such that the central portion bulges due to the elastic force from the connector terminal, the operation unit 4 is operated when mounted on the device body 1. The end of the unit 4 on the lock groove 12 side can be slightly overstroked toward the nose mounting surface 9 side by using the clearance C. therefore,
Even when the operation unit 4 is warped, the lock claw 7 can be locked in the lock groove 12 without being restricted in position by the nose mounting surface 9 when the operation unit 4 is mounted on the device body 1, and an excessive force is applied. Even if not, the locked state with the device body 1 can be easily obtained.

In the above-described embodiment, the case where the convex portion 9a is formed on the nose mounting surface 9 of the device body 1 has been described, but even if the similar convex portion is formed on the rear surface 4b of the operation unit 4, it is almost the same. The same effect can be obtained.

Further, even if the engaging mechanism, the locking mechanism, the unlocking mechanism or the like between the both ends of the operation unit 4 and the device body 1 is an in-vehicle device different from the above-mentioned embodiment, the present invention is directly applied. It goes without saying that you can do it.

The present invention is embodied in the form described above and has the following effects.

At least one of the nose mounting surface of the device body facing the mounted operation unit and the back surface of the operation unit facing the mounting surface is provided with a small projection having a minute height. Therefore, the back surface of the operation unit in the mounted state can be brought into point contact with the nose mounting surface of the device body instead of surface contact, so that even if the mounting surface or the back surface is painted, the coating due to heat does not occur. Sticking does not occur. As a result, the exposed surfaces of the operation unit and the device body can be painted in a desired color, and the designability can be significantly improved.

If the small protrusions are provided closer to a portion which is a pivotal fulcrum at the time of attachment / detachment than a portion constituting the lock mechanism in a state where the operation unit is attached to the main body of the apparatus, the small protrusion can be installed. It is possible to secure a clearance corresponding to the height of the small protrusion between the end of the operation unit on the lock mechanism side and the nose mounting surface of the device body. therefore,
Even when the operation unit that has been used for a long period of time has a warp such that the central portion bulges, the operation unit when mounted uses the clearance and the mounting surface is not restricted by the nose mounting surface. It can be overstroked to the side, and the locked state with the device body can be easily obtained without applying excessive force.
