Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a door for covering the front surface of an operating panel of an audio equipment, and in particular, it relates to a door for covering the front surface of an operating panel of audio equipment, and in particular, a door that automatically opens using a drive means and a switch. This relates to the door opening/closing mechanism that opens and closes the door.

[Prior Art] In an operation panel of an audio device, a door is provided to cover the front surface in order to prevent dust and improve the appearance.

As such a door, a rotating flat plate door as shown in FIG. 10 is widely used. In FIG. 10, an opening 32 is provided at the center of the front surface of an escutcheon 31 of the device, and an operation panel 33 is provided behind this opening 32. As shown in FIG. The opening 33 has a door 3 that covers the opening 33.
4 is provided on substantially the same plane as the front surface of the escutcheon 31. This door 34 is always urged in the opening direction by the urging force of a spring 35, and a closing pin 36 is provided at the end of the back surface thereof. On the other hand, a movable locking portion 37 is provided on the surface of the escutcheon 31 facing the opening 32 to lock the pin 36 from the front surface toward the rear. FIG. 11 shows such a locking portion 37.
FIG. That is, the locking portion 37 is normally held by elastic means (not shown).
As shown in A, the locking position is such that it protrudes inside the opening 32, and the pin 36 can be locked when facing backward from the front surface thereof. The front surface of the locking portion 37 is an inclined surface, and when this slope is pressed from the front by the pin 36, it is pushed into the non-locking position as shown in B. It's becoming like that. Further, as shown in FIG. 10, a push button 38 is provided near the locking portion 37 of the escutcheon 31, and when this push button 38 is pressed, the locking portion 37
7 is pushed into the unlocked position.

The door 34 in FIG. 10 having the above configuration
The operation is performed as follows. First, Figure 10A
When opening the door 34 from a closed state as shown in FIG. 1, the door 34 can be automatically opened by simply pressing the push button 38. That is, by pressing the push button 38, the locking portion 37 is pushed into the non-locking position, and the pin 36 is released. As a result, the door, now in its free state, is opened as shown in FIG. 10B by the biasing force of the opening spring 35. Further, when closing the door 34 from the open state as shown in FIG. 10B, the door 34 is rotated by pushing up the door 34 by hand against the biasing force of the spring 35. In this case, the pin 36 of the door 34 comes into contact with the inclined surface of the front surface of the locking part 37 in the locking position, so the door 34 is further held in this state.
4, as shown in FIG. 11B, the pin 36 pushes the locking part 37 into the non-locking position, and after overcoming this, the locking part 37 protrudes to the locking position again. Then, lock the pin 36 from the front side to the rear. Therefore, the door 34 is locked in the closed position as shown in FIG. 10A.

[Problems to be Solved by the Invention] However, in the door 34 configured as shown in FIG. 10, the door 34 can be opened automatically by pressing the push button 38, but when the door 34 is closed, Since the door 34 must be pushed up by hand, it has the disadvantage of poor operability. In particular, if the pin 36 provided on the back of the door 34 is not pushed in sufficiently until it is securely locked in the locking part 37, the door 34 will open due to the biasing force of the spring 35, and the door 34 will be forced open again. You'll have to push it up.

In addition, since the door 34 is opened using the spring 35, when the door 34 is opened, the door 34 collides with the device body 31, and as a result, a large load is applied to the structure around the door 34. It also has the disadvantage of causing damage and deformation, reducing durability.

On the other hand, when the operation panel 33 of the door opening/closing mechanism as shown in FIG. 10 is provided with a push-lock type operation means, the following disadvantages arise. Here, the push-lock type is a type that is movable in the front-back direction and is locked at two positions, front and rear, with different forward projection dimensions. An example of an arrangement in which such a push-lock type operation knob 39 is provided is shown. In this case, the closed position of the door 34 is determined by the operation panel 3 due to the miniaturization of the equipment.
3, and normally, as shown in FIG. It is arranged close to the operation knob 39 so that there is only a slight gap l between the two. In such an arrangement, when closing the door 34, the operating knob 39 must be pushed into the storage position before the door 34 is closed. However, if you accidentally try to close the door 34 when the operating knob 39 is not in the retracted position but in the operating position shown in FIG.
4 hits and it gets caught. In this case, in a door opening/closing mechanism in which the door 34 is closed by manual pressure, if the pressing force is strong, the door 34 may be deformed or damaged. In addition, for devices that use a drive motor to close the door,
Without a means to detect that the door has reached the closed position, the door 34 will be left in the partially open position with the operating knob 39 hooked, as shown in FIG. 13B. On the other hand, there is a type of door opening/closing mechanism that includes a switch that detects when the door has reached the closed position (end) and shuts off power to the drive motor in response to an end detection signal from the switch. This type of door opening/closing mechanism is usually equipped with a malfunction prevention mechanism, and if the end is not detected within a certain period of time, it is assumed that there has been an abnormality such as a jam, and the door is driven in the opening direction. Warning sounds and warning displays are now available. However, when the end detection mechanism and malfunction prevention mechanism are provided in this way, the number of parts such as switches and timers increases significantly, the configuration becomes complicated, and even if the operating knob 39 protrudes, the closing operation cannot be performed as it is. This results in wasted time and driving power.

The present invention was proposed to solve the problems of the prior art as described above, and its purpose is to:
Both opening and closing operations of the door can be performed automatically at a stable speed using a drive means, providing a highly stable door opening/closing mechanism with excellent operability and no risk of damage or deformation. It is to be.

In addition, in a configuration in which a push-lock type operating means is provided in the operation panel section, when the operating means is in a forward position with a large protruding dimension, it eliminates the possibility of accidentally closing the door. The purpose is to improve the safety of the vehicle, eliminate waste of time and driving power, and simplify the configuration.

are connected to each other, and can rotate in two directions depending on the rotational direction of the drive motor 6. Chassis 7
A guide gear 9 having the same pitch as the drive gear 8 is provided on the left side of the drive gear 8 .

As shown in FIG. 2, racks 11 are provided on both sides of the lower surface of the slide plate (slide member) 10, and the racks 11 mesh with the drive gear 8 and guide gear 9 to rotate the drive gear 8. It is designed to slide back and forth. In this case, the slide plate 10 is provided with a long guide hole 10a in the front-rear direction, and a guide pin 12 fixed to the upper surface of the chassis 7 is inserted into the guide hole 10a, so that the slide plate 10 is guided in the front-rear direction. It is becoming more and more like this. A door plate 13 is stacked on top of the slide plate 10, and both members are connected via a connecting spring 14. According to the sliding direction of the slide plate 10, the door plate 13 moves forward. to a closed position or a rearward open position. In this case, like the slide plate 10, the door plate 13 is provided with a guide hole 13a that is elongated in the front-rear direction, and this guide hole 13a
The guide pin 12 fixed to the upper surface of the chassis 7
By inserting it, it is guided in the front and back direction. In addition, by resisting the elastic force of the connection spring 14, the door plate 13

A closing switch 17 is provided at a position facing the rear end of the door plate position 3 and is fixed to the upper surface of the chassis 6, so that the door plate 13 is further moved from the rear open position to the slide plate 10. When the door plate 13 moves rearward by a predetermined distance, it is pressed against the rear end of the door plate 13.

As shown in FIG. 3, the push-lock knob 18 of the operating knob 4 is provided with a regulating switch (regulating means) 19 that turns on and off in conjunction with the push-lock knob 18, and is connected to the circuit of the closing switch 17. There is. This regulating switch 19 is turned on when the operating knob 4 is in the rear storage position as shown in FIG. 3A, operating the circuit of the closing switch 17, and When the operating knob 4 is in the forward operating position as shown in FIG. 3, it is turned off and the circuit of the closing switch 17 is cut off.

In addition, the door opening/closing mechanism of this embodiment as described above is specifically designed to control a case where the radio section, the deck section, and the control section are arranged in three layers, one above the other, as shown in Fig. 4. Used as a door opening/closing mechanism.

Next, the operation of the door opening/closing mechanism of this embodiment will be explained.

First, in the closed state of the door 15 as shown in FIGS. 5A and 6A, in order to open the door 15, press the opening "PUSH" display part of the door 15. The opening switch 5 is pressed via the button. As a result, a release signal is sent from the release switch 5 to the drive motor 6, and the drive motor 6 starts rotating. Due to this rotation, the drive gear 8 starts rotating clockwise in FIG.
As a result, the slide plate 10 slides rearward (to the right in the figure), and the door plate 13 moves in the opening direction via the connection spring 14.
FIG. 6B shows such a state in the middle of opening. In this case, the door 15 of the door plate 13 is
It is pushed up to the upper end of the inner locking part 20. Finally, as shown in FIG. 6C, the door 1
5 and the door plate 13 are the slide plate 1
0 and is housed in the chassis 7, and the front side of the operation panel 3 is completely opened as shown in FIG. 5B.

Next, when closing the door 15 from the open state as shown in FIG. 5B and FIG. Door plate 1
3 moves rearward against the connection spring 14 and presses the closing switch 17 at its rear end. As a result, a closing signal is sent from the closing switch 17 to the drive motor 6, and the drive motor 6 starts rotating. This rotation causes the drive gear 8
starts rotating counterclockwise in FIG. 6, the slide plate 10 slides forward (to the left in the figure), and the door plate 1
3 moves in the closing direction. In this case, door 15
is gradually rotated downward by the closing spring 16 as it is pulled out to the front of the inner case 20. Finally, as shown in FIG. 6A, the door 15 that has been completely pulled out to the front of the chassis 7 is rotated downward by the biasing force of the closing spring 16, and as shown in FIG. 5A. As shown, the front side of the operation panel 3 is completely closed.

As explained above, in this embodiment, both the opening and closing operations of the door are performed by the drive motor 6.
This can be done automatically using the driving force of , and the speed can be stabilized. In particular, regarding the closing operation, in the conventional technique shown in FIG. 10, the door 34 had to be pushed up by hand, which had the disadvantage of low operability. Since the closing switch 17 provided at the rear of the door plate 13 is simply pressed by pressing the door plate 13, the operability is excellent. Also, as in the past, the door 34
Since the door 15 is not opened by the spring 35, no large impact force is applied to the area around the door 15, so there is no risk of damage or deformation, and safety is excellent. In this case, in this embodiment, a closing spring 16 is used, but unlike the opening spring used in the prior art, this closing spring 16 is different from the opening spring used in the prior art, and the dead weight of the door 15 also has a closing force. Since it works as a spring, it is sufficient to use a spring with extremely small biasing force.
Since the structure is such that it acts gradually, there are no problems such as impact force related to the load.

Furthermore, in this embodiment, since a regulating switch 19 is provided which is interlocked with the push lock volume 18 of the operating knob 5, when the operating knob 14 is in the operating position protruding forward, the door may be accidentally blocked. The fear of doing something is gone. That is, as shown in FIG. 3B, when the operating knob 4 is in the forward operating position, the regulating switch 19 is turned off and the circuit of the closing switch 17 is cut off. 15 is pressed and the closing switch 17 is pressed, the closing switch 17
A blockage signal is not sent from the drive motor 6 to the drive motor 6, and blockage can be reliably prevented. Therefore, safety in this respect is improved, and there is no wastage of time or driving force. Furthermore, compared to the case where an end detection mechanism and a malfunction prevention mechanism are provided, the number of parts is smaller and the configuration is simpler.

Note that the present invention is not limited to the above-mentioned embodiment, and the guide configuration of the slide plate 10 can be changed as appropriate. For example, as shown in FIG. It is also possible to provide a structure in which the inside is slid.

Further, the closing switch 17 is connected to the door plate 1.
3, it is also possible to adopt a configuration in which the pressing operation is performed using a protrusion 13c provided on a part of the door plate 13, as shown in FIGS. 8 and 9. . Figure 8 shows door plate 1
Raise a part of 3 upward and close the blockage switch 17.
is provided above the door plate 13, and FIG. 9 shows an example in which a part of the door plate 13 is bent downward, the protrusion 13c is made to protrude below the slide plate 10, and the closing switch 17 is slid. This is an example in which it is provided below the plate 10.

Furthermore, instead of providing a regulating switch, a regulating means for mechanically stopping the door member may be provided as the regulating means.

[Effects of the Invention] As explained above, according to the present invention, both the opening and closing operations of the door can be automatically performed at a stable speed by the door driving means, and the operability is excellent and damage is prevented. It is possible to provide a highly safe door opening/closing mechanism that does not cause any risk of deformation or deformation. In addition, in a configuration in which a push-lock type operating means is provided in the operation panel section, when the operating means is in a forward position with a large protruding dimension, it eliminates the possibility of accidentally closing the door. improve safety,
Eliminates waste of time and driving force. Furthermore, there is an advantage in simplifying the configuration.
