Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter opening / closing mechanism, and more particularly, to a shutter that can be easily opened / closed as a shutter for a display of an operation panel of a vehicle and a protective cover of the operation.

[0002]

2. Description of the Related Art As shown in FIGS. 8 (A) and 8 (B), an instrument panel of an automobile is provided with an operation device / display device such as an audio device or an air conditioner at a central position between a driver seat and a passenger seat. A center display unit 1 (abbreviated as CDU) which is a module in which the above items are combined is provided.
By the way, the operation panel 4 of the CDU 1 may be covered with a shutter 3 that can be opened and closed in order to prevent malfunction and improve design, and in particular, when the room is exposed to the outside such as an open car, Operation panel 4 on CDU1
A shutter is provided as a protective cover to protect from rain and wind. In addition, as the shutter 3, a user manually opens and closes the shutter, and an automatic shutter using the power of a motor is proposed.

[0003]

However, in the completely manual type shutter 3, as shown in FIG. 8B, the user opens and closes the shutter 3 from the accommodating portion 2 and sets it in a predetermined position. All of the above have to be done by the user, and the operation is very troublesome. On the other hand, in the case of the automatic shutter, there is a problem that the cost is increased because a motor and a control function must be provided.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a semi-automatic shutter which has good operability in opening and closing operations and which does not increase the cost.

[0005]

In order to solve the above problems, the present invention opens and closes a shutter, which is a protective cover for opening and closing a protected portion of a display unit and / or an operating unit mounted on a vehicle, in a semi-automatic manner. A shutter opening / closing mechanism, wherein a slit-shaped accommodation port through which the shutter enters and exits is formed in a front panel of the display device and / or the operation device, and a loop-shaped guide rail is provided inside the accommodation port. A telescopic guide pin that slides on the guide rail is connected to one end of the shutter to continuously change the width of the guide rail in the sliding direction.
The expansion guide pin is urged in the extension direction, and as the expansion guide pin automatically slides on the guide rail in the direction in which the width of the guide rail expands, the shutter connected to the expansion guide pin is The opening / closing mechanism of the shutter is provided, which is characterized by automatically entering and exiting through the accommodation opening. In the guide rail, the looped outward path may be used as a passage when the shutter is closed and the return path may be used as a passage when the shutter is opened.

According to the above structure, the operation of housing the shutter in the housing opening when the shutter is closed and the operation of pulling the shutter out of the housing opening when the shutter is opened can be performed automatically instead of manually. it can. The power source for the shutter operation utilizes the urging force of the extension guide pin in the extension direction.
That is, since the width of the guide rail in which the telescopic guide pin is slidably fitted is continuously changed,
By the urging force in the extension direction, the telescopic guide pin automatically slides in the direction in which the width of the guide rail expands.
The shutter is automatically put in and taken out through the accommodation opening to open and close in conjunction with the sliding movement of the expansion and contraction guide pin.

When the telescopic guide pin slides along the loop-shaped outward path of the guide rail, the shutter automatically pops out from the accommodation opening, and when sliding along the loop-shaped return path. The shutter is automatically sucked into the accommodation opening.

Therefore, the operability of opening and closing the shutter can be improved, and since the motor and the control device are not used, it is possible to manufacture at low cost.

The extension guide pin is connected to the shutter by a link via a spring, and the distance and angle between the extension guide pin and the shutter are variable.

In the opening / closing operation of the shutter, the shutter draws the same locus at the time of opening and at the time of closing by merely moving in and out of the accommodation port, whereas the telescopic guide pin has a guide rail fitted therein. Since it is a loop, it will draw different trajectories when it is opened and when it is closed. Therefore, by connecting the expansion guide pin to the shutter with a link via the spring,
The distance and angle between the telescopic guide pin and the shutter can be made variable, and it is possible to absorb the difference in the loci.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. The shutter 12 of the present embodiment has the structure shown in FIG.
Center display unit (CDU) 10
It is used as a protective cover for the operation panel (protected portion) 13.

As shown in FIGS. 1 to 6, the shutter 12 vertically projects a latch 12c near the lower end 12a and connects one end of a link 17 near the upper end 12b. The other end of the link 17 is connected to a piston portion 18 in a tubular portion 16 described later. The tube portion 16 is
An expansion guide pin 15 in the depth direction of the drawing is provided at the upper end, and a piston portion 18 to which the other end of the link 17 is connected is slidably accommodated in the internal space, and the expansion guide pin 15 and the piston portion 18 Spring S1 in between
Is intervening.

The telescopic guide pin 15 is fitted in the guide rail 14 formed in a loop shape, and as shown in FIG. 7, both ends 15a and 15b which are relatively slidable.
A spring S2 is interposed between them to urge them in the extension direction. The width of the guide rail 14 in the depth direction of the paper in FIG. 1 is changed. That is, as shown in FIG. 7 which is a development view of the guide rail 14 formed in a loop shape, the distance between the wall surfaces 12a with which both ends of the extendable guide pin 15 are in sliding contact is continuously made different.

A shutter 12 is provided above the operation panel 13.
The storage port 11 is horizontally formed in a slit shape, and when the upper end of the shutter 12 is inserted into the storage port 11, the telescopic guide pin 15 is slidable on the loop-shaped guide rail 14 provided inside the panel. Fits inside.

FIG. 1 shows a state in which the shutter 12 is horizontally accommodated in the CDU 10 through the accommodation port 11 (open state), and the operation panel 13 is exposed. In this state, the latch 12c of the shutter 12 is locked to the panel side, the expansion / contraction guide pin 15 is arranged at the position A, the piston portion 18 in the cylindrical portion 16 is pulled up by the link 17, and the spring S1 is compressed. It is in a state of being.

In the state shown in FIG. 1, the lower end portion 12 of the shutter 12 is
When a is pushed to release the locking, as shown in FIG. 7, the spring S2 extends and the telescopic guide pin 15 automatically moves in the direction in which the width of the guide rail 14 expands.
Stop at the position. That is, as shown in FIG.

Thereby, the user can pull out the shutter from the accommodation opening 11 only by pushing the lower end portion 12a of the shutter 12, and by stopping at the position B, the shutter 12 does not violently collide with the operation panel 13.

From this state, as shown by the arrow in FIG. 2, the lower end portion 12a of the shutter 12 is pushed and the latch 12 is pushed.
c is locked to the locked portion 19 under the operation panel 13.
At this time, the expansion / contraction guide pin 15 moves to the position C where the width is narrowed against the spring S2.

Next, FIGS. 4 to 6 show an operation of opening the shutter 12. When the lower end portion 12a of the shutter 12 is pushed as shown in FIG. 4 from the state shown in FIG. 3, the shutter 12 is unlocked, and the piston portion 18 is pushed downward by the extension of the spring S1 in the tubular portion 16. At the same time, the telescopic guide pin 15 moves from the C position to the D position.

The telescopic guide pin 15 rides over the rib 14b at the D position, and then the spring S2 extends to automatically slide in the direction in which the width of the guide rail 14 widens and stop at the E position. That is, as shown in FIG.

From this state, the lower end portion 1 of the shutter 12 is
By pushing in 2a, as shown in FIG. 6, the telescopic guide pin 15 moves over the rib 14a via the F position and moves to the A position, and the latch 12c is locked to the panel side. At this time, the piston portion 18 in the tubular portion 16
Is pushed upward against the spring S1.

In the opening / closing operation of the shutter 12, the shutter 12 draws the same locus when opened and closed, whereas the telescopic guide pin 15 draws different loci when opened and closed. Therefore,
The expansion guide pin 15 is formed by the piston portion 18 connected by the link 17 and the tubular portion 16 including the spring S1.
By varying the distance and angle between the shutter 12 and the shutter 12, the above difference in the trajectory is absorbed.

With the above arrangement, when the shutter 12 is closed, the user only has to perform the pushing operation twice, and the shutter 12 can be automatically pulled out from the accommodation port 11. Similarly, when the shutter 12 is opened, the push operation only needs to be performed twice, and the shutter 12 is automatically sucked into the accommodation port 11. Therefore, the operability of the opening / closing operation of the shutter 12 can be improved, and since the semi-automatic is realized without using a motor or a control device, the manufacturing cost can be reduced.

[0023]

As is apparent from the above description, according to the present invention, the telescopic guide pin is automatically slid in the direction in which the width of the guide rail is widened by the urging force of the telescopic guide pin in the extension direction. By utilizing this, it is possible to automatically perform the operation of housing the shutter in the housing opening when the shutter is closed and the operation of pulling the shutter out of the housing opening when the shutter is opened. Therefore, the operability of the opening / closing operation of the shutter can be improved without using a motor or a control device, and the manufacturing cost can be reduced.

Further, the expansion guide pin is connected to the shutter by a link via the spring, and the distance and angle between the expansion guide pin and the shutter are made variable so that the expansion guide pin can be closed and opened. The difference in the loci of can be absorbed.
