Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for opening and closing a panel provided on an in-vehicle audio device or the like for operation or display.

[0002]

2. Description of the Related Art In recent years, in audio equipment and navigation equipment provided in a vehicle, a panel for operation or display is configured to be openable and closable so that a disc is stored in the back of the panel and the disc or the like is opened when the panel is opened. Consideration is being given to making it possible to take it in and out.

An example of the structure is shown in FIGS. 10 and 11. In the figure, a panel housing recess 202a is provided at an appropriate position on the fixed side panel 202, and a chassis 201 that opens forward is provided behind the panel housing recess 202a. Chassis 2
A storage space S as shown in FIG. 11 is secured in 01. The storage space S accommodates, for example, recording media for audio and navigation (compact disc, mini disc, cassette tape, etc.).
An insertion opening 202b is formed in the panel storage recess 202a, and a recording medium is taken in and out of the storage space S through the insertion opening 202b.

An opening / closing panel 205 is housed in the panel housing recess 202a. The open / close panel 205 includes an operation unit 203 including buttons and the like, and a display unit 204 including a display and the like, and is closed to be vertically held in the panel storage recess 202a as shown in FIGS. 10 and 11A. It is possible to open and close the position and the open position where the closed position is developed as shown in FIG. 11C.

The chassis 20 is used as the opening / closing device.
A slide member 20 that can slide in the front-back direction
6 is installed, and its front end is connected to the lower end of the opening / closing panel 205 so as to be relatively rotatable via a pin 205a. A protrusion 2 protruding laterally is provided on the top of the opening / closing panel 205.
05b is provided, and the projection 205b is provided with a guide groove 207 provided on the inner surface of the side wall front portion of the panel storage recess 202a.
It is fitted inside. The guide groove 207 extends in the vertical direction, and has a shape in which a lower end portion thereof is curved in an arc shape slightly forward.

In this apparatus, when the slide member 206 slides forward from the closed position shown in FIG. 11 (A), the upper end of the open / close panel 205 descends while the open / close panel 205 inclines with the slide ( (B) in the figure, the open / close panel 205 finally reaches an open position where it is substantially horizontal ((C) in the figure). In this state, a recording medium such as a cassette tape, a CD, an MD can be easily taken in and out of the storage space S.

[0007]

The panel is generally provided in the vicinity of the driver's seat and is often operated by the driver while seated and viewing the display. To facilitate confirmation of such operations and displays, for example, FIG.
As shown in (a), the operation panel 205 is opened so that the operation panel 205 jumps up (that is, the lower end portion of the panel floats to the front side), and the operation panel position in this open state is raised so that the operation panel 205 is operated at the open position. (In the illustrated example, the position of the insertion opening 202b is lowered as the panel is flipped up).

However, when the above-mentioned flip-up motion is performed, if the gap 208 between the upper surface of the opening / closing panel 205 and the top wall of the panel housing recess 202a is small, the upper end of the panel 205 moves from the closed position to the open position. Interferes with the ceiling wall (see the chain double-dashed line in FIG. 12B), and the opening / closing panel 205 cannot be opened. Therefore, in order to enable such a panel operation, the gap 208 must be increased, and the appearance becomes worse accordingly.

In view of such circumstances, the present invention allows the opening / closing panel to be opened to a position preferable for its operation and display confirmation while keeping the gap between the upper end of the opening / closing panel in the closed state and the peripheral edge of the panel storage portion small. It is an object of the present invention to provide a panel opening / closing device capable of performing the above.

[0010]

As a means for solving the above-mentioned problems, the present invention provides an opening / closing panel provided on a fixed side panel in a panel storage portion provided on the fixed side panel. A panel opening / closing device that moves between a closed position to be housed and an open position that expands forward and upward from the closed position, wherein a drive output unit that outputs a driving force for opening and closing, and a drive output unit of the drive output unit. A drive conversion mechanism that causes the open / close panel to perform a small turning operation of turning around the front end of the upper end or the vicinity thereof by output and then perform a main turning operation to the open position, is provided. As a conversion mechanism, a fixed side member including the fixed side panel and a member fixed to the fixed side panel, and a slide drive in the front-rear direction by the output of the drive output unit, and at least the front side. The fixed-side member is supported so as to slide in a region corresponding to a small turning motion while moving up and down, and is connected to the opening / closing panel so as to be relatively rotatable at a predetermined rotation fulcrum above the lower end portion thereof. Provided between the fixed side member and the open / close panel, and the open / close panel is configured so that the open / close panel performs the small turning motion and the main rotating motion in accordance with the forward sliding motion of the slide member. And a guide mechanism for guiding the.

According to this structure, the opening / closing panel is not first turned to the open position, but the opening / closing panel is first rotated at its upper end front portion or its upper end front portion so as not to interfere with the peripheral edge of the panel storage portion. Since a small turning operation is performed around the vicinity, and then the main turning operation is performed to the open position, the gap between the top end of the open / close panel and the peripheral edge of the panel storage part is kept sufficiently small, but there is no interference between the two and it is good. The opening / closing panel can be opened and closed, and the opening / closing panel can be deployed at a relatively high position that is easy for the user to operate.

In the present invention, as the drive conversion mechanism, a fixed side member including the fixed side panel and a member fixed to the fixed side panel, and a slide output in the front-rear direction by the output of the drive output unit, and While being supported by the fixed side member so as to slide at least in a region corresponding to the small turning motion while being moved up and down,
A slide member that is connected to the open / close panel so as to be relatively rotatable at a predetermined rotation fulcrum above the lower end of the open / close panel, and is provided between the fixed-side member and the open / close panel. And a guide mechanism for guiding the open / close panel so that the open / close panel performs the small turning motion and the main rotating motion in accordance with the sliding motion.

According to this structure, the slide member slides forward or downward from the closed position, so that the open / close panel receives the guidance of the guide mechanism to perform the small turning operation, and then the slide operation of the slide member. With this, the main rotation operation is performed to the closed position.

In this device, the drive converting mechanism is configured to return the open / close panel to the closed position by the reverse drive force of the drive output section from the movement from the closed position to the open position. Is more preferable. As a result, the open / close panel is automatically driven in both the opening direction and the closing direction.

In order to slidably support the slide member as described above, for example, a protrusion is provided on one of the slide member and the fixed member, and the other end extends in the front-rear direction and is fitted with the protrusion. At least the front end portion of the guide groove may be curved so that the opening / closing panel rotation fulcrum of the slide member makes a circular motion around the rotation center of the small turning motion as well as providing a guide groove to be recessed.

Further, the guide mechanism includes a projecting portion provided on one of the open / close panel and the fixed member and a guide groove provided on the other side, into which the projecting portion is fitted. The guide groove is formed in a shape corresponding to a small turning guide portion having an arc shape centering on the turning center of the small turning operation or a shape similar thereto, and a trajectory drawn by a predetermined portion of the opening / closing panel in the main turning operation. It is preferable to continuously have the above-described main rotation guide portion.

To slide the slide member while raising and lowering the slide member by the output of the drive output unit, for example, the output end of the drive output unit is a pinion, and a rack meshing with the pinion is attached to the slide member in the sliding direction. At least a part of the rack may be curved so that the meshing surface of the rack and the pinion always maintains a constant meshing height, regardless of the vertical movement of the slide member during sliding. .

According to this structure, it is not necessary to move the pinion up and down according to the slide member, and the slide member is combined with the slide and the lift with a simple structure in which at least a part of the rack is curved. It is possible to perform complicated operations.

The drive conversion mechanism may be independent, but if the drive conversion mechanisms are provided on both the left and right sides and these drive conversion mechanisms are connected to the left and right ends of the opening and closing panel, the opening and closing panel is supported and the opening and closing drive is performed. It can be performed in a more stable state.

A storage space for the recording medium can be secured between the left and right drive conversion mechanisms, and the recording medium can be taken in and out of the storage space below the open / close panel in the open position. It is also possible to do.

The rotational force of the double gear 36 is transmitted to the other slide member 19 via the transmission shaft 37 and the other double gear 36,
As a result, the left and right slide members 19 are simultaneously driven to slide.

Further, as a feature of this device, the shape of the rack 19r is an irregular shape along the through groove 20. That is, the front side portion of the rack 19r has an arcuate shape or a substantially arcuate curved shape (arcuate shape in the illustrated example) in the direction of lowering toward the front, and the rear side portion of the rack 19r has a substantially arcuate direction of decreasing toward the rear. The curved surface of the rack 19r and the pinion 36p are kept at a substantially constant height regardless of the vertical movement associated with the slide of the slide member 19.

From the front end of the slide member 19, a shaft supporting portion 19a extends obliquely upward. On the other hand, on the back surface of the opening / closing panel 16, a pair of left and right connecting portions 16 projecting rearward from a position above the lower end (a substantially intermediate position in the figure).

In addition, in the proper place of the fixed side panel 10,
A through hole 10d into which the connecting portion 16b is inserted from the front when the panel is closed is provided (FIG. 8).

A circuit board 40 is fixed to the bottom of the lower chassis 12. On the circuit board 40, two limit switches 41 and 42 are mounted in addition to the control circuit element. The limit switch 41 detects that the slide member 19 has retracted to the rearmost position (the position corresponding to the panel closed position).
2 is to detect that the slide member 19 has advanced to the frontmost position.

Specifically, a downward operating portion 19e is formed at the rear end of the slide member 19. On the other hand, each of the limit switches 41, 42 has a detection unit 41a,
The swinging members 43 and 44 cover the horizontal shaft 41 so as to cover 42a.
It is mounted so as to be swingable around b and 42b, and operated portions 43a and 44a are provided so as to project upward at the swinging end portions of the swinging members 43 and 44, respectively.

When the slide member 19 reaches the slide front end position and the slide rear end position, the operating portion 19e operates the operated portions 43a and 44a of the swinging members 43 and 44, respectively. The oscillating members 43 and 44 that have moved are the detecting portions 41 of the limit switches 41 and 42.
a, 42a. The operating portions 19e of the brackets 43, 44 reliably move (i.e., do not swing) even though the slide member 19 slides while moving up and down.
It is provided in consideration of operating the detection units 41a and 42a.

Next, the operation of this device will be described.

1 and 2 show a state in which the open / close panel 16 is in the closed position. In this state, the slide member 19 is retracted to the rearmost position, and the projecting portion 16c of the opening / closing panel 16 is located at the substantially uppermost end of the guide groove 26 provided in the fixed side panel 10. This fixed side panel 10
And the slide member 19 allows the open / close panel 16 to
The panel 10 is held in an upright state in a panel storage recess 10a (see FIG. 5 etc.).

When a command signal to open the panel is input to the control circuit of the circuit board 40 from this closed position, the control circuit activates the motor 31 of the drive output section 30 to cause both of the drive output section 30 to operate. The pinion 37 is rotated in the forward direction (clockwise direction in FIG. 1). As a result, the slide member 19 starts to slide forward.

At the beginning of the slide, the lower chassis 12
Since the side pin 13 is located inside the curved portion 21 of the through groove 20, the slide member 19 slides forward while sinking. On the other hand, the protrusion 16 c at the upper part of the opening / closing panel 16 moves along the inside of the small-turn guide portion 27 of the guide groove 26. as a result,
The opening / closing panel 16 performs a small turning motion of rotating around the upper end front portion 16p or the vicinity thereof (FIG. 5). By this small turning operation, the opening / closing panel 16 is prevented while avoiding interference between the panel upper end front portion 16p and the peripheral edge of the panel storage recess 10a.
Can be tilted to an appropriate angle.

Next, the pin 13 is connected to the straight portion 22 of the through groove 20.
When the slide member 19 moves to, the slide member 19 slides straight forward while maintaining its height, while the protrusion 16
c descends substantially straight in the main rotation guide portion 28 (FIG. 6). Then, the pin 13 causes the curved portion 23 on the rear side of the through groove 20 to be curved.
When the slide member 19 enters, the slide member 19 continues to slide while moving upward, and accordingly, the protrusion 16c advances along the lower end portion of the main rotation guide portion 28, that is, the portion curving forward. When it reaches the end, as shown in FIG. 7, the lower end of the open / close panel 16 is flipped up high, and the open / close panel 16 reaches the open position where the open / close panel 16 itself faces substantially upward. At this point, the slide member 1
The operating portion 19e of 9 operates the operated portion 44a of the swinging member 44 provided on the front limit switch 42, and the swinging member 44 swinging by this operation causes the limit switch 42 to swing.
The detector 42a of is operated. As a result, the slide member 1
It is detected that 9 has reached the foremost end position, and the operation of the motor 30 is stopped at that time.

In this open position, the driver can easily operate the switches (check the display if the open / close panel 16 has a display portion) while sitting. Also,
Since the open position is at a relatively high position, the upper insertion opening 10b
Not only can the disc D or the like be inserted into or removed from the upper housing 14 through the lower housing 12, but also the disc D or the like can be inserted into or removed from the lower chassis 12 through the lower insertion opening 10c without any trouble.

If the opening / closing panel 16 is suddenly rotated from the closed position shown in FIG. 1, the upper end of the opening / closing panel 16 and the fixed side panel 1 shown in FIG.
If the gap 11 with the peripheral edge of the opening 0 is small, the upper end of the opening / closing panel 16 interferes with the peripheral edge of the opening when the opening / closing panel 16 is rotated, and the opening operation cannot be performed. Therefore, the gap 11 must be increased. In the device shown in this embodiment, first, the opening / closing panel 16 is caused to perform a small turning motion centered on the upper end front part 16p or the vicinity thereof, and thereby the posture is adjusted, and then the main turning motion is performed to the open position. Therefore, it is possible to perform the opening operation without difficulty while keeping the gap 11 small. Therefore, by reducing the gap 11, it is possible to improve the appearance and prevent dust and the like from entering the interior of the panel.

When a command signal for returning from the open position to the closed position is input, the reverse operation of the motor 30 is performed. As a result, the pinion 36p rotates in the reverse direction (counterclockwise direction in FIG. 7), and as a result, the opening / closing panel 16 returns to the closed position in FIG. 1 by an operation that is completely opposite to the above-described opening operation. That is, the opening / closing panel 16 performs the main rotation operation to a position near the closed position as shown in FIG. 5, and then performs a small turning operation to be set in the closed position. At the time of returning to the closed position, as shown in FIG. 1, the operating portion 19e of the slide member 19 operates the operated portion 43a of the swinging member 43 provided on the limit switch 41 on the rear side. The swinging member 43 operates the detecting portion 41a of the limit switch 41. As a result, a detection signal is output from the limit switch 41,
The control circuit receiving the signal stops the reverse operation of the motor 30.

The operation in the closing direction may be manually performed by the user.

In addition, the present invention can take the following embodiments.

In the above embodiment, the opening / closing panel 16 is provided with the projection 16c, and the fixed side panel 10 is provided with the guide groove 26. On the contrary, the opening / closing panel 16 side is provided with the guide groove.
A protrusion that fits in the guide groove may be provided on the fixed side panel 10 side. Further, it is possible to provide the protrusion or the guide groove not on the fixed side panel 10 but on the chassis 12 side.

In the present invention, the rack 19r of the slide member 19 can be linear. In this case, at least the pinion 36p of the drive output unit 30 can be moved up and down, and the pinion 36p is biased toward the rack 19r,
It suffices that the pinion 36p and the rack 19r always keep meshing with each other regardless of the elevation of the slide member 19. However, if the rack shape as shown in the figure (the shape that curves in accordance with the lifting operation of the slide member 19) is used, the drive output unit 3
It is possible to maintain the meshed state of the pinion 36p and the rack 19r without complicating 0.

The small turning guide portion 27 does not have to have a strict circular arc shape, and may have a shape similar to this. In short, any shape may be used as long as the small turning operation can be realized while avoiding the interference between the upper end front portion 16p of the opening / closing panel 16 and the peripheral edge of the panel storage recess.

In the above-described embodiment, the drive conversion mechanism DM is provided on the left and right sides. However, when it is not necessary to secure a storage space for a recording medium, a single drive conversion mechanism DM is used. The open / close panel 16 may be supported.

The "panel housing portion" according to the present invention is not limited to surrounding the opening / closing panel 16 over the entire circumference like the panel housing recess 10a, and has at least a wall portion facing the upper end of the opening / closing panel 16. All you have to do is do it. Therefore, for example, the lower end of the open / close panel 16 in the closed position may be opened downward.

In the present invention, the open / close command signal for the open / close panel 16 can be set appropriately. For example, it may be configured such that the ACC terminal, which is operated by operating the engine key of the vehicle, is turned on / off, and the opening operation is performed by ACC-ON and the closing operation is performed by ACC / OFF.
