Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle electronic device having an operation unit on the front surface of a device body such as an on-vehicle audio system, and more particularly to a model capable of detaching the operation unit from the device body. And for the model in which the operation unit is fixed so as not to separate from the device body,
The present invention relates to a vehicle-mounted electronic device to which an operation unit having the same structure can be applied.

[0002]

11 and 12 are perspective views of a vehicle-mounted electronic device (vehicle-mounted audio device) in which an operation unit is rotatably provided. The device body 1 is composed of a chassis 2 and a nose portion 3 provided in the front portion thereof. The chassis 2 is embedded in a storage recess formed in a console panel or the like in an automobile, and the nose portion 3 is installed so as to be substantially flush with the front surface of the console panel. Chassis 2
A drive mechanism for a cassette tape, a disc selection drive mechanism for selecting and driving a plurality of discs (compact disc (CD) or mini disc (MD)), and the like are housed inside. Further, the chassis 2 has an FM and AM tuner, an audio amplifier, and a control circuit built therein. An operation unit 4 is provided on the front surface 3 a of the nose portion 3. A display device 5 such as a liquid crystal panel and various operating bodies 6 such as push buttons are provided on an operation panel on the front surface of the operation unit 4. A pair of support pieces 7 are provided on both sides of the front surface 3a of the nose portion 3,
The operation unit 4 is rotatably supported on the support piece 7 by a support shaft 8.

FIG. 11 shows a state in which the operation unit 4 is in a closed posture overlapping the front surface 3a of the nose portion 3, and FIG.
Shows a state in which the operation unit 4 is rotated forward with the support shaft 8 as a fulcrum, and the front face 3a is exposed and in an open posture. In the open position of FIG. 12, the front surface 3a of the nose portion 3 is exposed, and a recording medium such as a cassette tape or a plurality of disks can be inserted and ejected from the medium insertion opening 3b opened in the front surface 3a. Figure 11
In the closed position shown in FIG. 3, the operation panel of the operation unit 4 occupies the entire front surface of the device body, and various operations are performed by the operation body 6, for example, driving operation of cassette tape or disk, AM or FM.
The channel selection operation and the like are performed, and various operating states can be displayed on the display device 5.

There are two types of this kind of vehicle-mounted electronic equipment. The first method allows the operation unit 4 to be arbitrarily detached from the device body 1. In this method, by removing the operation unit 4 from the device body 1 and carrying the operation unit 4 alone outside the vehicle, it becomes impossible to operate the device body 1 and the device body 1 is prevented from being stolen from the inside of the vehicle. Can be prevented. In the second method, the operation unit 4 is attached so that it cannot be removed from the device body 1. This is the device body 1
Is used in an area where there is no risk of being stolen from the inside of the vehicle, or when it is assumed that the operation unit and the device body 1 are integrated and taken out when going out of the vehicle.

[0005]

As described above, there are two types of in-vehicle electronic devices, that is, the operation unit 4 is removable from the device body 1 and the one that is not removable.
The structure inside the device body 1 is common to both models, and the basic structure and appearance design of the operation unit 4 are also common to both models. However, one model requires a mechanism for locking the operation unit 4 to the device body 1 and a detaching operation mechanism for removing the operation unit 4 from the device body 1, and the case of the operation unit 4 and the nose portion 3 are required.
Must have a structure capable of accommodating each of the above mechanisms.
On the contrary, in a device in which the operation unit 4 cannot be removed from the device body 1, it is not necessary to house the above-mentioned mechanisms in the operation unit 4 and the nose portion 3. Therefore, when designing and manufacturing an in-vehicle electronic device, the nose portion 3 and the operation unit 4 are not combined with each other as described above.
It must be tailored to each type of equipment. Therefore, the case of the operation unit 4 and the nose portion 3
Since it is necessary to separately provide a mold for injection molding in order to have a structure adapted to each model, the manufacturing cost becomes high. Further, the case of the nose section 3 and the operation unit 4 is different for each model, and it is necessary to manage parts for each model, which also increases the manufacturing cost.

In the case where the operation unit 4 is detachably provided from the nose portion 3, an operating body for rotating the operation unit 4 from the closed posture shown in FIG. 11 to the open posture shown in FIG. It is necessary to provide an operation button) on the front surface of the operation unit 4, and an operation body for detaching the operation unit 4 from the device body 1 in the closed posture shown in FIG. 11 is required. As described above, when the operation body for rotating the operation unit to the open posture and the operation body for detaching the operation unit 4 from the device body 1 are separately provided, each operation body is supported in a movable state. Since the mechanism for this is separately provided inside the same operation body 4, the structure in the operation unit 4 becomes complicated. Further, there is a high possibility that the two types of operating bodies provided in the operation unit 4 are mistakenly operated, and for example, when the operation unit 4 is rotated from the closed posture shown in FIG. 11 to the open posture shown in FIG. As a result, there arises a problem that the operation unit 4 is detached from the device body 1.

The present invention solves the above-mentioned problems of the prior art. For example, a nose part or a model in which the operation unit can be detached from the device body or the operation unit is not detached from the device body. The purpose is to enable the case of the operation unit to be used as a common part.

Further, according to the present invention, when the operation unit is rotatable with respect to the device body and the operation unit is detachable from the device body, the operation unit can be rotated and removed by a single operation body. The purpose is to enable.

The operation unit 30 is attached / detached to / from 0. In FIG. 4, the locking hook 26 a at the tip of the rotation lock member 26, which is urged clockwise by the tension spring 28, is locked to the lock piece 22 of the rotation base 20, and the rotation base 20.
Is locked in a closed posture overlapping the front surface 12a of the nose portion 12. That is, the rotation base 20 is locked by the rotation lock mechanism including the rotation lock member 26 and the lock piece 22.

When the operation unit 30 is mounted on the rotation base 20 in the locked state, first, the fixing hook projection 3 on the right end face of the case 31 of the operation unit 30 is attached.
4 is fitted into a retaining hole 24a provided at the right end of the rotary base 20 in the figure. Then, when the operation unit 30 is rotated in the direction of the rotation base 20 with the fitting portion between the fixed hooking protrusion 34 and the hooking hole 24a as a fulcrum, the movable hooking protrusion 35a is formed.
Is locked in the locking hole 24b at the left end of the rotation base 20 in the figure. That is, in the movable latching mechanism K1, the slider 35 is slidable in the storage space S, and the return spring 39 causes X1.
Since the movable latching protrusion 35a slides inside the latching piece 23b of the rotation base 20, the movable latching protrusion 35a temporarily retracts from the elongated hole 31b and further returns to the return spring. It is projected into the retaining hole 24b by the urging force of 39.
As a result, the operating unit 30 is locked with respect to the rotation base 20 by the disengagement lock mechanism formed by the movable engagement protrusion 35a and the engagement hole 24b so as not to be disengaged.

When the operation unit 30 is mounted on the rotary base 20 and the rotary base 20 and the operation unit 30 are in the closed posture shown in FIG. 4, the convex connector 41 provided on the back surface of the operation unit 30 has the nose. Front surface 12a of part 12
It is fitted to the concave connector 42 formed on the. Therefore, the operation body 33 arranged on the operation panel 31a on the surface of the operation unit 30 can instruct the operation of various mechanisms and circuits in the device body 10. Further, the illumination unit of the operation panel 31a can be illuminated by the electric power sent from the device body 10, and the display device 32 can be operated.

When loading the cartridge C into the device body 10 from 2b or ejecting the cartridge C from the device body 10, the first operating body 36 is pushed in the first direction (Y2 direction). When the operating body 36 is pressed, the drive shaft 37 integrated with the operating body 36 passes through the elongated hole 31d of the case 31 and pushes the tip of the rotation lock member 26 in the device body 10. Since the shaft 27, which is the center of rotation of the rotation lock member 26, is located below the hook 26a at the tip of the rotation lock member 26, the tip of the rotation lock member 26 is pushed by the drive shaft 37. The member 26 rotates counterclockwise as shown by the chain line in FIG.

As a result, the hook 26a is locked by the lock piece 2.
2, the lock by the rotation lock mechanism is released. When the lock is released, the elastic force of the torsion spring 25 causes the rotation base 20 and the operation unit 30 attached to the rotation base 20 to rotate to the open position shown by the chain line in FIG. In the open position, the rotation base 20 and the operation unit 30 are in a position substantially perpendicular to the front surface 12a of the nose portion 12, and the upper part of the front surface 12a of the nose portion 12 is exposed. The insertion opening 12b formed on the exposed front surface 12a

When the operation unit 30 in the open position shown by the chain line in FIG. 4 is returned to the closed position, the operation unit 30 is manually rotated in the counterclockwise direction in FIG. Operation unit 30
Is returned to the solid line state, the locking hook 26a of the rotation lock member 26 is locked by the lock piece 22 of the rotation base 20, and the rotation base 20 and the operation unit 30 are locked again. When the first operating body 36 is slid in the second direction (X2 direction) in the closed posture shown by the solid line in FIG. 4,
That is, when the first operation body 36 is slid in the direction along the surface of the operation panel 31a, the drive shaft 37 causes the slider 35 to move.
Is moved in the X2 direction, the movable locking projection 35a protruding from the elongated hole 31b is retracted, and the movable locking projection 35a comes out of the locking hole 24b. This allows the operation unit 30 to be detached from the rotation base 20 and the device body 10. By taking the detached operation unit 30 out of the vehicle and carrying it, it becomes possible to prevent the on-vehicle electronic device from being stolen.

The tip end of 26 is pushed, the rotation lock member 26 rotates counterclockwise, and the locking hook 26a of the rotation lock member 26 and the lock piece 22 are unlocked.
Then, due to the elastic force of the torsion spring 25, the rotation base 20 and the operation unit 30 rotate to the open posture shown by the broken line in FIG. Then, the front surface 12a of the nose portion 12 is exposed, and the cartridge C can be taken in and out from the insertion opening 12b. In the above embodiment, the movable hooking mechanism K1 is used.
When the lock by the rotation lock member 26 is released in both the model in which is stored and the model in which the fixed locking mechanism K2 is stored, the elastic force of the torsion spring 25 causes the rotation base 20 and the operation unit. 30 and 30 can be rotated in the opening direction. However, it is also possible to rotate the rotation base 20 and the operation unit 30 by the power of the motor. For example, the support shaft 1 is attached to the rotation base 20.
