Description

  The present invention relates to a panel drive device that, when opening a panel, rotates the panel after translation.

  In a conventional in-vehicle panel drive device, in order to emphasize designability, the front panel of the panel drive device and the design panel in the vehicle are arranged on the same curve, and the front panel is almost in the design panel in the vehicle. Some are configured to be stored without gaps. In this case, if the panel is opened only by the pivoting operation, the panel comes into contact with the surrounding design panel. Therefore, when opening the panel, it is necessary to translate the panel to a position protruding from the design panel, and then move to a rotation operation (see, for example, Patent Document 1).

  In the panel driving device disclosed in Patent Document 1, one end is pivotally connected to the lower part of the panel and is movable in the front-rear direction, and an arm whose one end is pivotally connected to the upper part of the panel; And a power transmission mechanism interposed between the arm and the slide member. In this power transmission mechanism, when the slide member is moved forward from the retracted position, the arm is translated substantially integrally with the slide member, and the panel is erected. The panel is tilted by relatively translating.

Japanese Patent No. 3821325

  However, in the panel driving device disclosed in Patent Document 1, the position of the arm rotation shaft is fixed by the power transmission mechanism when the panel is rotated, and thus the rotation speed of the arm cannot be controlled. There was a problem that the rotation speed of the panel could not be controlled. For this reason, when positioning is performed by bringing the panel into contact with the stopper when the panel is opened, there is a problem that the panel collides with the stopper at a high speed and a collision noise is generated. In addition, there is a problem that the panel vibrates due to a sudden movement change from the translation operation to the rotation operation, and a collision sound of the component parts is generated by this vibration.

  The present invention has been made to solve the above-described problems. In a panel driving device that rotates after translating the panel when opening the panel, the rotational speed of the arm is controlled with a simple configuration. Thus, an object of the present invention is to provide a panel drive device that can control the rotational speed of the panel.

The panel drive device according to the present invention includes a panel storage portion provided on an end surface of the main body device, a panel which is stored in the panel storage portion and can be opened and closed on the side opposite to the main body device side, and a first fulcrum of the panel.

Via a second arm pivotally connected to the main body device, an arm pin provided on the second arm, and an arm pin formed on and engaged with the slide base. and a cam groove for controlling the rotational speed of the second arm, the cam groove includes a first cam profile for projecting & Shelves from the panel accommodating unit by translating the panel, the main unit side of the first cam profile is formed, the second rotating the panel And arm-shaped portion is formed on the main unit side of the second cam profile, and a third cam profile which the rotational speed of the panel to decelerate the panel open state, the first cam profile, a slide Inclining by the first angle with respect to the moving direction of the slide base so that the translation amount of the second fulcrum by the rotation of the first and second arms is substantially the same as the translation amount of the base, The second cam shape portion has a small second angle with respect to the first angle so as to reduce the translation amount of the second fulcrum by the rotation of the first and second arms with respect to the translation amount of the slide base. The third cam-shaped portion is inclined with respect to the second angle so that the translation amount of the second fulcrum by the rotation of the first and second arms follows the translation amount of the slide base. It is characterized by being formed to be inclined by a large third angle .

Embodiment 1 FIG.
As shown in FIG. 1, the panel drive unit 1 is provided with a panel housing 3 on the end surface (for example, the front surface) of the main body device 2. The panel housing 3 is provided with a media insertion slot 4 through which a recording medium such as a music CD (Compact Disc) or a DVD (Digital Versatile Disc) is taken in and out of the main body device 2.
In addition, the panel housing 3 is provided with a panel 5 that can be opened and closed on the side opposite to the main body device 2 side (for example, in front of the main body device 2). A display unit 6 and operation keys 7 are arranged on the panel 5. In the panel storage state, the panel 5 is stored in an upright state in the panel storage unit 3 as shown in FIG. On the other hand, when the recording medium is taken in and out of the main unit 2, the panel 5 is opened to expose the media insertion slot 4 (panel open state) as shown in FIGS.

  Further, in order to emphasize designability, the panel 5 is arranged on the same curve as the edge of the design panel 2 a of the main body device 2 and the panel storage unit 3, and is stored in the panel storage unit 3 with almost no gap. Therefore, when the panel 5 is opened, in order to prevent contact with the panel storage unit 3, it is necessary to shift the panel 5 in the panel storage state to a position protruding from the panel storage unit 3 and then to move to a rotation operation.

Next, a mechanism for opening and closing the panel 5 in the panel drive device 1 as described above will be described with reference to FIGS. In FIG. 2, only the left side portion is shown as viewed from the back side of the panel driving device 1, but the right side portion is also configured in the same shape. 3 to 6, a chassis 11 and a guide plate 15 described later are not shown.
As shown in FIGS. 2 to 6, engagement protrusions 5 a and 5 b are formed on the upper and lower portions of both side surfaces of the panel 5. In addition, a U-shaped slide base 8 is provided on the back surface of the panel 5 so as to be movable in the panel mounting direction with respect to the main body device 2 (one end can protrude and retract from the panel storage portion 3). An engagement hole 8a is formed at one end of both side walls of the slide base 8, and an engagement protrusion (first fulcrum) 5a is rotatably connected.
Cam grooves 9 extending in the front-rear direction are formed on both side walls of the slide base 8. The cam groove 9 controls the rotation speed and rotation angle of the second arm 18 via an arm pin 20 described later. The shape of the cam groove 9 will be described later.

A first guide groove 10 extending in the front-rear direction is formed on the bottom surface of the slide base 8. Two chassis collars 12 a and 12 b that are rotatably provided on the bottom surface of the chassis 11 of the main body device 2 are engaged with the first guide groove 10. A guide pin 13 is attached to the rear side of both side walls of the slide base 8, and a slide collar 14 is rotatably attached to the guide pin 13.
On the other hand, guide plates 15 fixed to the chassis 11 are provided outside the both side walls of the slide base 8. A second guide groove 16 extending in the front-rear direction is formed on the rear side of the guide plate 15, and an engaging protrusion 15a is formed on the front side. The slide collar 14 is engaged with the second guide groove 16.

  Thus, the slide base 8 is driven by an electric drive device (not shown) by the engagement of the chassis collars 12a and 12b with the first guide groove 10 and the engagement of the slide collar 14 with the second guide groove 16. It is configured to be movable only in the front-rear direction by force.

A substantially L-shaped first arm 17 whose one end can protrude and retract from the panel housing 3 is provided on the back surface of the panel 5. An engagement hole 17a is formed at one end of the first arm 17 and is rotatably connected to an engagement protrusion (second fulcrum) 5b. An engagement hole 17 b is formed at the other end of the first arm 17. Further, the first arm 17 is formed with a stopper 17c with which one end of a first torsion coil spring 25 described later is engaged.
An engagement hole 18 a formed at one end of a substantially L-shaped second arm 18 is rotatably connected to the engagement hole 17 b by a pin 19. An engagement hole 18b is formed at the other end of the second arm 18, and is rotatably connected to the engagement protrusion 15a. An arm pin 20 that engages with the cam groove 9 is attached to the lower end of the second arm 18 on the other end side.

  A panel contact portion 21 is provided at the upper end of the back surface of the panel 5. As shown in FIG. 3, the panel storage portion 3 is provided with a first positioning portion 22 that contacts the panel contact portion 21 in the panel storage state. Further, as shown in FIG. 6, the panel storage portion 3 is provided with a second positioning portion 23 that comes into contact with the panel contact portion 21 in the panel open state. The maximum inclination angle of the panel 5 is positioned by the second positioning portion 23. Further, as shown in FIG. 3, a recess 24 is formed on the back surface of the panel 5 to prevent contact between the panel 5 and the second positioning portion 23 when the panel is housed.

Further, a first torsion coil spring (first elastic member) 25 is attached to the second arm 18 and the first arm 17 via a pin 19. The first torsion coil spring 25 has one end engaged with the stopper 17 c of the first arm 17 and the other end engaged with the second arm 18, so that the first arm 17 is always at an angle with the second arm 18. Energize in the direction of narrowing (panel opening direction).
The second arm 18 is formed with an arm stopper 26 that contacts the first arm 17. The arm stopper 26 restricts the angle between the second arm 18 and the first arm 17 so as not to be smaller than a slightly wider angle than the panel 5 can be completely closed.
Further, a second torsion coil spring (second elastic member) 27 is attached to the second arm 18 and the chassis 11 via an engagement protrusion 15a. One end of the second torsion coil spring 27 engages with the chassis 11 and the other end engages with the second arm 18, thereby biasing the second arm 18 in the direction in which the second arm 18 is always raised (panel storage direction).

Next, the configuration of the cam groove 9 configured as described above will be described.
The cam groove 9 changes the height of the position of the arm pin 20 engaged by the movement of the slide base 8, and accordingly, the second arm 18 is rotated about the engagement hole 18b. As shown in FIG. 7, the cam groove 9 has three types of cam-shaped portions 9a to 9c corresponding to the panel state.
The 1st cam shape part 9a is a part in which the arm pin 20 is located between a panel accommodation state after a panel translation (after protrusion). The first cam-shaped portion 9a is a second fulcrum by the rotation of the first and second arms 17 and 18 with respect to the translation amount of the first fulcrum (engagement protrusion 5a) of the panel 5 due to the movement of the slide base 8. It is formed in a shape (inclination angle) such that the translation amount of the (engagement protrusion 5b) is substantially the same. Thereby, the panel 5 can be translated and protruded / stored from the panel storage portion 3.

  The second cam-shaped portion 9b is a portion where the arm pin 20 is positioned between the state after panel translation and the state immediately before the panel opening (the state immediately before the panel opening state (maximum inclination angle)). The second cam-shaped portion 9b reduces the translation amount of the second fulcrum due to the rotation of the first and second arms 17, 18 with respect to the translation amount of the first fulcrum of the panel 5 due to the movement of the slide base 8. It is formed in such a shape (small inclination angle with respect to the first cam shape portion 9a). Thereby, the position in the front-rear direction of the first fulcrum and the second fulcrum of the panel 5 can be relatively separated, and the panel 5 can be rotated upward.

  The 3rd cam shape part 9c is a part in which the arm pin 20 is located between the panel open state immediately before the panel open state. The third cam-shaped portion 9 c causes the translation amount of the second fulcrum caused by the rotation of the first and second arms 17 and 18 to follow the translation amount of the first fulcrum of the panel 5 due to the movement of the slide base 8. It is formed in such a shape (a large inclination angle with respect to the second cam shape portion 9b). Thereby, it can suppress that the position of the front-back direction of the 1st fulcrum of the panel 5 and a 2nd fulcrum is left | separated, and the rotational speed of the panel 5 can be decelerated.

Next, the operation of the panel drive device 1 configured as described above will be described with reference to FIGS. Below, the operation | movement at the time of opening the panel 5 is demonstrated.
In the panel storage state shown in FIG. 3, the panel 5 is pressed and held against the panel storage portion 3 side by the arm stopper 26 and the second torsion coil spring 27. That is, the first torsion coil spring 25 urges the first arm 17 toward the second arm 18 (panel opening direction), but in the panel storage state, the arm stopper 26 does not move the second arm 18 toward the second arm 18 side. Since it is restricted, the urging force by the first torsion coil spring 25 does not act. In the panel storage state, the second torsion coil spring 27 urges the second arm 18 in the direction in which the second arm 18 is raised (panel storage direction). At the same time, the arm stopper 26 also urges the first arm 17 in the panel storage direction.
Therefore, in the panel storage state, the panel 5 is held in a state where the panel contact portion 21 is always pressed against the first positioning portion 22. Thereby, it can suppress that the panel 5 rattles by vibration etc.

  When the slide base 8 is advanced from the retracted position by the electric drive device from such a panel storage state, the arm pin 20 moves upward along the first cam shape portion 9a. As a result, the second arm 18 rotates in the panel advancing direction with the engagement hole 18b as a fulcrum, and the first arm 17 pushes out the panel 5. Here, the first cam shape portion 9a controls the rotation speed and the rotation angle of the second arm 18 so that the translation amounts of the first fulcrum and the second fulcrum of the panel 5 are substantially the same. Therefore, the panel 5 translates while standing, and is in a state of protruding from the panel housing 3 (post-translational state) as shown in FIG.

  Further, when the panel 5 is being translated, if the angle between the first arm 17 and the second arm 18 begins to gradually open, the urging force of the first torsion coil spring 25 starts to act, An urging force is applied in the direction in which the panel 5 is pushed out. For this reason, the panel 5 can be moved from the panel storage portion 3 without contact even when the gap between the panel storage portion 3 and the panel 5 is small, and the design is improved.

  Thereafter, when the slide base 8 is further advanced from the state shown in FIG. 4, the arm pin 20 is gently moved upward along the second cam-shaped portion 9b. As a result, the second arm 18 gently rotates in the panel advancing direction with the engagement hole 18b as a fulcrum, and the first arm 17 pushes out the panel 5. Here, the second cam-shaped portion 9b controls the rotation speed and the rotation angle of the second arm 18 so that the positions of the first fulcrum and the second fulcrum of the panel 5 in the front-rear direction are relatively separated. Yes. Therefore, the panel 5 starts to rotate upward from the standing state and rotates to a state shown in FIG. 5 (a state immediately before the panel contact portion 21 and the second positioning portion 23 abut).

  Thereafter, when the slide base 8 is further advanced from the state shown in FIG. 5, the arm pin 20 is accelerated along the third cam-shaped portion 9c and moved upward. As a result, the second arm 18 accelerates and rotates in the panel advancing direction with the engagement hole 18b as a fulcrum, and the first arm 17 pushes out the panel 5. Here, the second cam-shaped portion 9b controls the rotation speed and the rotation angle of the second arm 18 so that the first and second fulcrum positions of the panel 5 are relatively close to each other. Yes. Therefore, the rotation speed of the panel 5 is decelerated, and the panel 5 comes into contact with the second positioning portion 23 while gently rotating, so that the panel is opened as shown in FIG. Thus, by reducing the rotational speed of the panel 5 immediately before the panel 5 is in the panel open state, the collision sound between the panel contact portion 21 and the second positioning portion 23 can be reduced.

  When the panel is open, the position of the second arm 18 is fixed by the contact between the arm pin 20 and the rear end of the cam groove 9, and the angle between the second arm 18 and the first arm 17 by the first torsion coil spring 25. Is biased in the direction of narrowing (the direction in which the panel 5 is pressed against the slide base 8). Therefore, it can suppress that the panel 5 shakes by vibration etc.

With the above operation, the panel 5 is opened and the media insertion slot 4 is exposed, so that the user can insert and remove the recording medium from the main unit 2 via the media insertion slot 4.
When the panel 5 is housed in the panel housing portion 3 from the panel open state, the slide base 8 is moved backward. As a result, the panel 5 operates in the opposite direction to the above operation and can shift to the panel storage state.

As described above, according to the first embodiment, the slide base 8 is connected to the first fulcrum of the panel 5, the first arm 17 is connected to the second fulcrum of the panel 5, and the first arm 17 is connected to the first arm 17. Since the connected second arm 18 is configured to be controlled to rotate by the cam groove 9 of the slide base 8, the rotation speed and the rotation angle of the second arm 18 can be controlled with a simple configuration. The rotation speed can be controlled.
In addition, immediately before the panel 5 is in the panel open state, the second arm 18 is positioned on the rear side of the cam groove 9 so that the first and second fulcrum positions of the panel 5 are relatively close to each other. Since the third cam-shaped portion 9c that increases the rotation speed is provided, the rotation speed of the panel 5 can be reduced, the panel 5 is prevented from colliding with the second positioning portion 23 at a high speed, and the collision sound is generated. Can be reduced.

In addition, since the conventional panel driving apparatus has only one arm, when the elastic member is used to urge the arm to prevent rattling due to the vibration of the panel, the arm is moved in the panel storage direction or the panel opening. It could only be energized in one direction. Therefore, in the case where the panel is not in the urging direction by the elastic member, rattle noise due to rattling when the panel vibrates may occur.
On the other hand, in the panel drive device 1 according to the first embodiment, the two arms 17 and 18 are provided, the first torsion coil spring 25 that urges the first arm 17 in the panel opening direction, and the second arm 18 are housed in the panel. Since the second torsion coil spring 27 biased in the direction is provided, the panel abutting portion 21 is moved to the first positioning portion 22 or the panel 5 regardless of whether the panel 5 is in the panel storage state or the panel open state. The second positioning portion 23 can be pressed and held, and rattling when the panel 5 vibrates can be suppressed to reduce the generation of vibration noise. Moreover, the opening and closing of the panel 5 by vibration can also be suppressed.

In the first embodiment, the arm stopper 26 is formed on the second arm 18, but may be formed on the first arm 17.
Further, in the present invention, any constituent element of the embodiment can be modified or any constituent element of the embodiment can be omitted within the scope of the invention.
