DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle electronic device in which a display area and an operation area are enlarged by providing a movable nose in front of a main unit.

[0002]

2. Description of the Related Art In general, on-vehicle electronic devices such as car audios have various operation keys and a display unit, a tape cassette and a C / C on a front panel mounted on the front of a main unit.
Although an insertion port for inserting a medium such as D is provided, when the display unit is enlarged or the number of operation keys is increased with the recent multifunctionalization, these display units, operation keys and It becomes difficult to dispose all the insertion ports and the like in the limited space of the front panel.

On the other hand, an on-vehicle electronic device disclosed in Japanese Utility Model Laid-Open Publication No. 6-4612 or the like has an insert for inserting a medium into a front panel (fixed nose) fixed to the front of a main unit. An opening is provided, and a movable nose is installed at a position covering the insertion opening so as to be tiltable. The movable nose is provided with a display unit and various operation keys,
The insertion opening can be opened and closed by moving the movable nose between a predetermined standing posture (steady posture) and a tilting posture. In an in-vehicle electronic device having such a movable nose, the entire front surface of the movable nose in the upright posture can be used as a display area or a key operation area, and the movable nose is rotated only when a medium is inserted or ejected. Since the insertion opening only needs to be exposed, a relatively large display unit and a large number of operation keys can be arranged in a limited space.

However, in the case of a vehicle-mounted electronic device in which the movable nose is moved between the standing posture and the tilting posture, only a partial area of the front panel is exposed even when the movable nose is tilted. However, there is a problem that it is difficult to secure a space for disposing the display unit and the operation keys on the front panel. Also, because the movable nose protrudes forward in a tilted posture when the front panel is exposed,
When a passenger in the cabin moves his hand near the front panel,
There was a problem that the movable nose in a tilted position became an obstacle.

Therefore, the present applicant has previously filed Japanese Patent Application No. 11-02 / 1999.
No. 3881 proposes an in-vehicle electronic device in which a movable nose can be housed in a main unit by a driving force of a motor. According to this conventional proposal, after the movable nose in a steady position covering the front of the front panel is rotated by approximately 90 degrees, the movable nose can be inserted into the space of the main unit via the opening of the front panel. Therefore, the insertion port, the display unit, the operation keys, and the like can be arranged with a margin in a wide area of the front panel. Further, when the front panel is exposed, the movable nose in the housed state does not interfere, so that the usability is improved. In addition, since the movable nose can be automatically changed by the driving force of the motor, the operability is excellent.

[0006]

As described above, although the vehicle-mounted electronic device proposed in Japanese Patent Application No. Hei 11-023881 has various advantages, the movable nose accommodated in the space of the main unit is not limited. The end face is exposed in the opening of the front panel, and the dust and the like easily enter the main unit through the gap in the space defined around the movable nose in the storage position, and the like. There is still room for improvement in that there are factors that reduce it.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided an electronic device for a vehicle in which a movable nose is accommodated in a space of a main body device. Opening is automatically covered with a door member, and the opening and closing mechanism of the door member is simplified as much as possible. In such an in-vehicle electronic device, the end surface of the movable nose housed in the space of the main body device and the gap in the space defined around the movable nose are covered with the door member and are not exposed. In addition, even when the movable nose is stored, there is no need to worry about spoiling the appearance and unity, and there is no need to worry that the surface of the movable nose in the storage position is contaminated with dust or the like.

Reference numeral 7 is elastically biased about the support shaft 36 in the direction of arrow F1. The state in which the upper side 37c of the selection member 37 is in contact with the spring hooking piece 34c is the allowable rotation limit of the selection member 37 in the F1 direction. Further, the winding portion of the torsion spring 38 has a function as a compression spring. That is, since the winding portion is interposed between the selection member 37 and the retaining member, the selection member 37 is always elastically pressed against the control plate portion 34a in the arrow G direction. .

At the rear end of the selection member 37, a small projection 39 is provided so as to project toward the control plate 34a. When the small projection 39 is in the arc guide portion 41 of the control plate portion 34a, the selecting member 37 can rotate within the length of the arc guide portion 41. However, when the small protrusion 39 is fitted into the lock portion 42 of the control plate portion 34a, the small protrusion 39 is retained in the lock portion 42 because the winding portion of the torsion spring 38 is urged in the direction of arrow G. Then, the selection member 37 is in the lightly locked state. Further, the front end of the selection member 37 is vertically branched via the groove 44, and the tip of the lower branch piece extending forward is the selection restricting portion 43a.

Is the sliding portion 43c.

Next, the attitude control operation of the movable nose 10 and the opening / closing operation of the door member 15 will be described.

As shown in FIG. 1, since the movable nose 10 in the normal posture covers the front of the front panel 3, the control surface 10a of the movable nose 10 is exposed in the vehicle interior. FIG.
FIG. 7A shows an operation state of the attitude control means 20 at this time. That is, as shown in FIG. 4, in the reciprocating drive mechanism 21, the rotating body 24 is stopped in a state where it is rotated clockwise to the final point, and the slider 23 is drawn into the housing 2 and stopped. . FIG. 7A
As shown in the figure, the control pin 32 of the posture switching arm 31 connected to the side surface 10d of the movable nose 10 is located at the front end of the upwardly inclined guide portion 33b of the bent piece 23b of the slider 23, and the distribution member 34 is located at the rear end of the normal posture path 35a. The control pin 32 also slides on the first sliding portion 43b of the selecting member 37 to move the groove 4
4 is inside. That is, the selection member 37 is rotated in the direction of the arrow F <b> 2, and is in the lightly locked state in which the small protrusion 39 is fitted into the lock portion 42. At this time, the door member 15 pivotally supported by the front panel 3 and urged by the spring member 16 in a direction to close the opening 7 is pushed into the movable nose 10 against the urging force of the spring member 16. Have been. For this reason, the door member 15 is held between the rear surface of the movable nose 10 and the fixed control surface 6 of the front panel 3 in a fully opened state that is substantially vertical.

When the movable nose 10 is moved from the normal position to the storage position, the rotating body 24 is moved by the driving force of the motor 29 by, for example, pressing an operation button provided on the control surface 10a. Rotate counterclockwise. Then, the rotating body 24 reaches the state of FIG. 6 through the state of FIG. 5, and the motor 29 stops. Meanwhile, the slider 23
The reciprocating movement of moving forward and backward is performed by the motion converting means 27. FIG. 5 shows a state where the slider 23 has advanced most forward. The movable nose 10 moves from the state of FIG. 7A to the state of FIG. 8 while the slider 23 advances from the state of FIG. 4 to the state of FIG. The state shifts to the state shown in FIG. Also, while the slider 23 is retracted from the state of FIG. 5 to the state of FIG.
The state shown in FIG. 8A shifts from the state shown in FIG. 8B to the state shown in FIG.

First, the process of moving the movable nose 10 from the normal position to the maximum protruding position will be described.
7A, the control nose 32 of the posture switching arm 31 moves forward in the steady posture path 35a of the control plate portion 34a, and the movable nose 10 in the steady posture moves forward without tilting from the state of FIG. 7B, the control pin 32 abuts on the front end of the steady posture path 35a. Further, as the movable nose 10 moves forward, the upright door member 15 gradually tilts by the urging force of the spring member 16.

When the slider 23 further advances from the state shown in FIG. 7B, the support pin 12 at the lower end of the movable nose 10 advances, but the control pin 32 is restricted and the support pin 13 cannot advance. The movable nose 10 is shown in FIG.
Rotating clockwise from the state shown in FIG. 8B, FIG.
State. In this process, the control pin 32 moves from the upper inclined guide portion 33b of the slider 23 to the lower inclined guide portion 33c via the linear guide portion 33a, and descends in the switching path 35c of the control plate portion 34a. Go. Then, as shown in FIG. 8A, when the control pin 32 reaches the rear end of the downward inclined guide portion 33c, the slider 23 is in the most advanced state, and at this time, the control pin 32 is moved to the lower end of the switching path 35c ( Since the movable nose 10 is located at the front end of the storage posture path 35b), the movable nose 10 has a maximum protruding posture in which the control surface 10a is horizontal. Also, the movable nose 10
Is rotated to the maximum projecting position, the door member 15 is pressed onto the projection 23f of the slider 23 by the urging force of the spring member 16, and the projection 23f supports the half-open door member 15.

Thereafter, since the slider 23 retreats, the control pin 32 is moved to the storage posture path 35 of the control plate portion 34a.
Retreat along b. Therefore, the movable nose 10 moves through the opening 7 into the housing 2 while keeping the horizontal posture, and is stored in the empty space 4. During the transition from the state of FIG. 8A to the state of FIG. 8B, the control pin 32 retreats in the storage attitude path 35b. In this process, the control pin 32 is the second side of the lower side of the selection member 37. The selection member 37 is rotated in the direction of the arrow F1 so that the small protrusion 39 is disengaged from the lock portion 42 of the control plate portion 34a and enters the arc guide portion 41. As a result, the lightly locked state of the selection member 37 is released, and the arc guide portion 41 is released.
The selecting member 37 is supported within the movable range of
Can be turned around the center. When it is detected that the movable nose 10 is completely stored in the empty space 4, the driving of the motor 29 is stopped.

When the movable nose 10 is thus stored in the space 4, the opening 7 is closed by the door member 15, as shown in FIG. 8B. That is, the lower end 10 b of the movable nose 10 and the lower end 10 b
If the gap in the space 4 defined around the outside is exposed on a part of the fixed control surface 6, the aesthetic appearance and the sense of unity are impaired. If you cover it, you will not feel strange when viewed from the outside. In addition, since dust and the like hardly enter the space 4 from the gap, the surface of the movable nose 10 in the storage position is less likely to be contaminated with dust and the like.

Next, the movable nose 10 in the retracted position is moved forward.
When standing up to the normal posture, the motor 29 is started and the rotating body 24 is rotated clockwise in FIG. 6 by the driving force. In the process in which the rotating body 24 shifts from the state of FIG. 6 to the state of FIG. 5, the slider 23 advances from the state of FIG. 8B to the state of FIG. Has advanced. Meanwhile, the control pin 32
Moves forward along the storage posture path 35b of the control plate portion 34a, but since the control pin 32 contacts the second sliding portion 43c of the selection member 37, the selection member 37 once rotates in the direction of arrow F2. Then, as shown in FIG. 9A, when the control pin 32 moves to the front end of the storage posture path 35b and separates from the selection member 37, the selection member 37 is rotated in the arrow F1 direction by the torsion spring 38, and this selection is performed. The front end of the storage attitude path 35b is closed by the selection restricting portion 43a of the member 37. Also, in this process, the door member 15 having closed the opening 7 abuts on the projection 23f of the slider 23 and is pushed open.

When the rotating body 24 further rotates clockwise from the state shown in FIG. 5, the slider 23 retreats, but the control pin 32 is blocked by the selection restricting portion 43a and cannot return to the storage posture path 35b. As shown in FIG. 9 (B), the control pin 32 lifted by the downwardly inclined guide portion 33c of the retreating slider 23 is guided into the switching path 35c of the control plate portion 34a. Therefore, as the slider 23 retreats, the control pin 32 slides in the linear guide portion 33a while being held in the switching path 35c, but the support pin 12 retreats, so that the upper end 10c of the movable nose 10 Is lifted upward, and the movable nose 10 rotates so as to stand up. When the slider 23 further retreats,
The control pin 32 is lifted by the upper inclined guide portion 33b to reach the upper end of the switching path 35c (the front end of the steady posture path 35a), and the movable nose 10 is in a vertically upright state as shown in FIG.

When the movable nose 10 rotates, the door member 15 is moved to the upper end 10c of the movable nose 10.
Of the slider 23 is separated from the projection 23f of the slider 23, and thereafter, is separated from the projection 23f of the slider 23.
Is pushed into the upper end surface and the back surface of the movable nose 10, and FIG.
As shown in FIG. 0 (A), the movable nose 10 is in elastic contact with the back surface.

When the slider 23 retreats further from the state shown in FIG. 10A, the movable nose 10 approaches the front panel 3 while standing up, as the control pin 32 retreats in the steady posture path 35a. As shown in FIG. 10 (B), the stationary posture is set to cover the fixed control surface 6. Therefore,
The door member 15 is pushed into the back surface of the movable nose 10, and the door member 15 is disposed between the back surface of the movable nose 10 in the normal posture and the fixed control surface 6 in the state of FIG. In this process, the control pin 32 is connected to the selection member 3.
7 and enters the first sliding portion 43b. Therefore, when the control pin 32 moves to the rear end in the groove 44, the selection member 37 is rotated in the direction of the arrow F2, and the small protrusion 39 coming out of the arc guide portion 41 is locked as shown in FIG. The selection member 37 enters the lightly locked state.

As described above, in this embodiment, when the movable nose 10 is inserted into the space 4 of the main unit 1 from the opening 7 of the front panel 3, the door member 15 is automatically opened.
Is closed, the end face of the stored movable nose 10 and the gap in the cavity 4 are covered with the door member 15 and are not exposed. In the process in which the movable nose 10 in the retracted position advances from the opening 7, the door member 15 is pushed open by the projection 23 f of the slider 23 and is held in a half-open state. The door member 15 can be pushed in at the corners, the upper end surface, the back surface, and the like of the movable nose 10 in the process of shifting to the steady posture while rotating approximately 90 degrees. Therefore, the control surface 10a of the movable nose 10, which is provided with the operation keys 11a, 11b, etc., is rich in unevenness.
However, there is no fear of interfering with the door member 15 and hindering its operation.

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

A front panel provided at the front of the main unit and having an opening for exposing a space in the main unit; a stationary position in which at least an operation member is disposed on the surface to cover the front of the front panel; A movable nose that can be selected from a stored posture rotated into the space by being rotated approximately 90 degrees from a posture, and a posture control that includes a slider and a motor drive unit and moves the movable nose between a steady posture and a stored posture. Means, and a door member provided so as to be able to open and close the opening, and when the movable nose is in the retracted position, the door member closes the opening and the movable nose moves forward from the opening. Since the movable nose is an in-vehicle electronic device configured to push and open the door member, the end surface of the movable nose stored in the cavity of the main device, and the gap in the cavity defined around the movable nose, No longer exposed it is covered with the A member. Therefore, even when the movable nose is stored, there is no need to worry about spoiling the beauty and unity, and there is no need to worry that the surface of the movable nose in the storage position is contaminated with dust or the like.

Further, if the slider is provided with a projection for supporting the door member in a half-open state, and the projection keeps the door member away from the surface of the movable nose, operation keys such as operation keys can be provided. Interference between the surface of the movable nose having the unevenness and the door member can be reliably avoided.
