Panel drive device

Technical field

TECHNICAL FIELD [0001] The present invention relates to a panel drive device that drives a movable nose that covers a front panel disposed on a front surface of a main body device of an in-vehicle device such as a car audio.

Background art

[0002] In an in-vehicle audio device such as a cassette tape player or a CD player, various operation keys, a display unit, or a media inlet have been arranged on a front panel attached to the front surface of the main unit. Since the display unit has become larger and the number of operation keys has increased along with the functionalization, all of these display units, operation keys, media inlets, etc. should be placed in a limited space on the front panel. Has become difficult.

[0003] To solve this problem, a media slot is provided on the front panel, a display unit and various operation keys are provided on the movable nose that covers the front panel, and this movable nose is mounted on the slide member. By rotating the movable nose in conjunction with the reciprocating motion of the slide member, the media inlet disposed on the front panel is closed with the movable nose, or the media inlet is exposed. It is comprised so that it can be in a state.

[0004] When the slide member is retracted to the retracted position as viewed from the operator, the movable nose is in an upright state, and the media slot entrance located behind the movable nose is covered by the movable nose. Yes. When the slide member is moved from the retracted position to the advanced position, the movable nose rotates about the rotation fulcrum and the lower end protrudes toward the near side, and the media moves along with the rotation of the movable nose.揷 entrance is exposed.

[0005] According to such a movable nose type panel drive device, the entire surface of the closed movable nose can be used as a display area or a key operation area, and the movable nose can be used only when a medium is inserted or ejected. Since it is only necessary to rotate and expose the media inlet, there is an advantage that a relatively large display portion and many operation keys can be arranged in a limited space. However, when the movable nose rotates, interference between the movable nose and the front panel becomes a problem. [0006] In relation to this problem, for example, the movable nose is configured to rotate around the guide pin by moving forward and backward together with the slide member. A movable nose that avoids contact between the movable nose and the front panel provided in the opening of the main unit due to the trace of the upper back of the main unit entering the inside of the main unit opening. As a means to solve the problem that the circuit board and circuit elements housed in the movable nose are greatly restricted, the upper and rear surfaces of the movable nose and the lower part of the movable nose are required. A slide member rotatably connected to the fulcrum, a driving means for moving the slide member in the front-rear direction of the main unit, and an assembly rotatably connected to the upper fulcrum of the movable nose. And a power transmission mechanism interposed between the arm and the slide member, and the arm is advanced substantially integrally with the slide member in the process of moving the slide member from the retracted position to the advanced position. Later, there is a technique for moving the slide member relatively forward with respect to the alarm (for example, see Patent Document 1).

[0007] Patent Document 1: Japanese Patent Laid-Open No. 2000-40882

[0008] However, in the panel drive device configured as described above, the position is determined by being pinched by two grooves, that is, the pivot fulcrum pin force provided on the arm, the groove of the slide member, and the groove of the power transmission mechanism. Therefore, if the backlash of the pivot point of the arm becomes large, the arm is twisted and as a result, when the posture of the arm and the movable nose becomes unstable with respect to the driving of the movable nose or the vibration from the outside, Interference with other parts may cause abnormal noise. Moreover, since the rotation fulcrum pin of the arm is not supported by the immovable member, there is a concern about the strength effect over time.

[0009] The present invention solves the above-described problems, and provides a panel drive device that reliably avoids interference between the movable nose and the front panel and enables a stable opening and closing operation of the movable nose. Objective.

The structure will be described with reference to these drawings.

A nose pin 5 is fixed to the lower part of the movable nose 3. The movable nose 3 is pivotally attached to the slide member 11 by a nose pin 5. That is, the nose pin 5 forms a lower fulcrum of the movable nose and is rotatably connected to the slide member 11 via the nose pin 5. The slide member is a U-shaped plate as shown in FIG. 3, and a nose pin 5 is supported on a rising portion 48 at the end in the width direction.

The slide member 11 is placed on a chassis 7 to which the main body device 1 is assembled. A long hole 40 formed in the slide member 11 in the front-rear direction is fitted with a pin 41 implanted in the chassis 7 to restrict the movement direction of the slide member 11 in the front-rear direction. A rack 42 is formed on the side part of the slide member 11 that is long in the front-rear direction. The pinion 43 meshes with this rack 42, the pinion 43 meshes with the small gear 44, and the large tooth coaxial with the small gear 44 A worm 46 fits in the car 45, and the worm 46 is connected to a motor 47 that can be rotated forward and backward.

The pinion 43, the small gear 44, and the large gear 45 are supported by the chassis 7. These long hole 40, pin 41, rack 42, pinini 43, / J, gear 44, large gear 45, worm 46, motor 47, etc. are for moving the slide member 11 in the front-rear direction of the main unit 1. It constitutes the drive means.

[0018] A slide pin 12 of the slide member 11 is implanted in the rising portion 48 at the end in the width direction of the slide member 11. The arm groove 9 is engaged with the slide pin 12. The arm groove 9 is an arc-shaped long groove formed in the arm 13. The middle part of the arm 13 is rotatably supported by a base pin 8 planted in the rising part of the chassis 7. An arm pin 6 is implanted in a portion of the arm 13 opposite to the side engaged with the slide pin 12, and this arm pin 6 engages with a nose groove 10 formed on the side of the movable nose 3. ing. Since the configurations of the nose pin 5, the arm pin 6, the base pin 8, the arm 13 and the like described for one side in the width direction are also provided on the opposite side in the width direction, they are denoted by the same reference numerals in FIG.

[0019] In the panel drive device having a force and a structure, the rotation and translational motion of the movable nose 3 pivotally attached to the slide member 11 is engaged with the slide pin 12 of the slide member 11 and the chassis 7 The arm 13 is pivotally attached to the arm groove 9 and the arm pin 6 of the arm 13 is engaged with the nose groove 10 of the movable nose 3 and the like.

[0020] The operation will be described with reference to FIGS.

An arm 13 that is rotatably connected by a base pin 8 fixed to the chassis 7 is provided with an arm groove 9 that engages with the slide pin 12 of the slide member 11, and is a slide that is driven by a driving means. The rotation angle of the arm 13 is determined by the translation amount of the member 11.

The movable nose 3 is provided with a nose groove 10 that engages with the arm pin 6 of the arm 13, and the movable nose 3 is rotatable with the nose pin 5 provided at the lower part of the movable nose 3 as a fulcrum. Both are connected.

In the panel drive device configured as described above, the posture of the movable nose 3 is a force determined by the translation position of the slide member 11 and the rotation angle of the arm 13. The rotation angle of the arm 13 is the translation of the slide member 11. The position of the movable nose 3 is determined by the position of the slide member 1 It is determined only by the translation position of 1.

[0023] Normally, as shown in FIG. 1, the movable nose 3 is stood and stored in the front panel 2. However, the movable nose 3 is rotated when a medium is taken in and out of the main unit 1. The media entrance 4 needs to be exposed. In that case, in order to make the gap between the front panel 2 and the movable nose 3 as small as possible, the movable nose 3 is moved together with the slide member 11 in the forward direction indicated by the arrow A as shown in FIG. Translate to.

In this case, the arm 13 is rotated by the slide pin 12 of the slide member 11 with the base pin 8 as a fulcrum, but the arm groove 9 provided in the arm 13 has the nose pin 5 and the arm pin 6 movable together with the nose 3 in the translational direction. Since the question that travels a certain distance is formed to move the same way, the movable nose 3 remains upright. Therefore, the upper end portion of the movable nose 3 moves outward without interfering with the overhang portion of the front panel panel 2.

Further, when the slide member 11 is translated, as shown in FIG. 5, the arm 13 rotates in the direction of the arrow B with the base pin 8 as a fulcrum. The arm pin 6 is movable nose more delayed than the nose pin 5 in the translation direction.
