Description

  The present invention relates to an in-vehicle panel device in which a movable panel having a display screen is disposed so as to be able to appear and retract in a casing, and in particular, configured so that the movable panel protrudes outward from the casing while tilting. The present invention relates to an in-vehicle panel device.

  In recent years, in order to enable passengers in the rear seats of a vehicle cabin to view televisions, DVDs, etc. in a comfortable posture, a movable panel having a display screen is retractably stored in, for example, a casing installed on the ceiling, An in-vehicle panel device configured such that the movable panel is tilted and protrudes outward from the housing is becoming widespread. In this type of in-vehicle panel device, since a thin casing is strongly desired, the movable panel must be stored in a substantially parallel posture with respect to the installation surface of the casing in the casing. In order to shift the movable panel to a desired tilt posture outside the housing, a drive mechanism is required that allows the movable panel to slide relative to the housing while changing the tilt angle.

Normally, in a conventional in-vehicle panel device equipped with such a drive mechanism, the front end of a slider (drive bracket) that moves back and forth by the drive force of a motor built in the housing is rotatable to the rear end of the movable panel. And a pivot arm interlocking with the slider via a cam mechanism is pivotally coupled to appropriate portions on both sides of the movable panel. Then, as the movable panel driven by the motor through the slider protrudes outward from the inside of the casing, the rotating arm advances obliquely forward of the casing and increases the tilt angle with respect to the slider. The movable panel connected to the arm shifts to a desired tilting posture (see, for example, Patent Document 1).
JP 2004-149057 A

  However, when the movable arm is connected to the movable panel as in the above-described conventional in-vehicle panel device, the movable panel is rotated to the rear of both sides of the movable panel during use when the movable panel is projected outward. Since the moving arm is exposed, there is a problem that the design is remarkably impaired. In addition, when the tilt angle of the movable panel with respect to the installation surface of the housing is as small as about 40 degrees, for example, a stable support structure that supports the movable panel with the tension force of the pivot arm cannot be realized. There was also a problem that play was likely to occur.

  The present invention has been made in view of the situation of the prior art as described above, and an object of the present invention is to realize a simple structure that does not require a rotating arm to be connected to a movable panel that leans out from the housing. Therefore, an object of the present invention is to provide an in-vehicle panel device that has improved design and is less likely to cause backlash.

  In the present invention, a drive bracket that slides in a housing using a motor as a drive source is rotatably connected to a rear end portion of a movable panel, and the tilt guide extends in a direction inclined with respect to the slide movement direction of the drive bracket. In the state where the rear extension part is introduced into the inclined guide part, the rear extension part of the integrated bracket fixed to the movable panel is slidably engaged with the guide groove having the part. The tilt angle of the movable panel is changed as the slide moves.

  According to the vehicle-mounted panel device of the present invention, the integral bracket is fixed to the movable panel driven by the driving means via the drive bracket, and the rear extension portion of the integral bracket has the inclined guide portion in the housing. Since the guide bracket is slidably engaged, if the drive bracket slides and moves with the rear extension portion being introduced into the inclined guide portion, the position of the movable panel changes as the posture of the integrated bracket changes. The tilt angle changes. Therefore, the movable panel can be protruded from the housing while being tilted and shifted to a desired tilting posture, and a simple structure that does not require the rotation arm to be connected to the movable panel can be realized. As a result, this in-vehicle panel device has significantly improved design as compared with the structure in which the rotating arm is exposed when in use, and can avoid backlash caused by the rotating arm. Reduction can be expected.

  An in-vehicle panel device according to the present invention includes a movable panel having a display screen, a casing having an opening for allowing the movable panel to enter and exit, driving means including a motor built in the casing, and the movable panel. A drive bracket that is pivotally connected to a rear end portion of the housing, and that is slidably moved in the direction close to and away from the opening by the driving means, and a driving member provided on a fixing member in the housing. A guide groove having an inclined guide portion extending in a direction inclined with respect to a moving direction of the bracket; and an integrated bracket having a rearward extension portion fixed to the movable panel and slidably engaged with the guide groove. The movable panel driven by the driving means via the drive bracket protrudes outward from the housing state housed in the housing and tilts by a predetermined angle. The reciprocating movement is possible between the extended state and the rearward extending portion of the integrated bracket is slidably engaged with the inclined guide portion, and the sliding movement of the drive bracket causes the movement of the drive bracket. The tilt angle of the movable panel was changed.

  In the in-vehicle panel device configured as described above, the integrated bracket is fixed to the movable panel driven by the driving means via the driving bracket, and the rearward extension portion of the integrated bracket serves as the inclined guide portion within the housing. When the drive bracket slides in a state where the rear extension portion is introduced into the inclined guide portion, the movable panel is moved as the posture of the integrated bracket changes. The tilt angle changes. Therefore, the movable panel can be protruded from the housing while being tilted to shift to a desired tilting posture, and there is no need to connect a rotating arm to the movable panel.

  In the above configuration, the guide groove has a parallel guide portion that communicates with the inclined guide portion, and the parallel guide portion is parallel to the sliding movement direction of the drive bracket on the back side in the housing with respect to the inclined guide portion. It is preferable that the movable panel extends, and the movable panel can be immersed in the casing in a posture parallel to the sliding movement direction of the drive bracket, so that the casing can be thinned easily. .

  In this case, a cushion member is attached in the vicinity of the opening in the housing, and an inclined closed end portion that is inclined to the opposite side to the side where the cushion member exists is formed at the back end portion of the parallel guide portion. By introducing the rear extension of the integrated bracket into the closed end, the cushioned member ensures the rattle noise of the movable panel during storage when it is configured to elastically contact the cushion member. Can be prevented. In addition, when the rear extension part of the integrated bracket is not introduced into the inclined closed end part of the guide groove, the movable panel and the cushion member can be kept out of contact with each other. There is no possibility that the cushion member will have an adverse effect.

  In the above configuration, the first chassis and the second chassis are fixed in the housing, the first chassis is provided with a guide groove, and extends linearly to the second chassis. Since the second guide groove is provided and the drive bracket is slidably engaged with the second guide groove, a simple and strong structure for smoothly sliding the drive bracket can be realized.

  Further, in the above configuration, when the casing is installed on the back surface of the seat in the vehicle interior, the movable panel protrudes above the casing and is arranged on the back side of the headrest of the seat. Since the passenger in the rear seat can see the display screen of the movable panel in an easy posture during use, the vehicle panel device is easy to use.

  In this case, the escape groove that communicates with the end of the guide groove on the opening side is formed, and the escape groove is provided with an erroneous entry prevention means that does not allow the rear extension portion to enter during normal use. When an excessive external force is applied from the headrest side to the movable panel tilted at a predetermined angle outside the housing, this external force causes the rear extension part to enter the escape groove against the erroneous entry prevention means. In this case, it is preferable for the passenger in the front seat to reduce the impact even if the headrest collides with the movable panel.

  As a means for preventing such erroneous entry, for example, a narrow portion is formed at the entrance portion of the escape groove, and when an external force that can widen the groove width of this narrow portion is applied, the rear extension portion passes through the narrow portion. Then, it may be configured to be able to enter the escape groove.

  In addition, a lever member urged by a spring member is provided in the housing as an erroneous entry preventing means, and the urging force of the lever member prevents the rear extension portion from entering the escape groove during normal use. When the external force acting against the urging force of the lever member is applied, the rear extending portion may be allowed to enter the escape groove. When the external force that resists the force is removed, the rearward extension portion can be quickly returned from the escape groove to the normal guide groove. Therefore, even when an external force such as the rear seat occupant forcibly pulling the movable panel toward the front acts during use, the movable panel can be rotated by allowing the rear extension part of the integrated bracket to enter the escape groove. Thus, a damage accident is less likely to occur, and if the external force is removed, the original use state can be automatically restored.

  In this case, the second lever member is rotatably held on a common spindle with the lever member, and the second lever member is spring-biased in a direction away from the lever member, and is movable. If the second lever member is configured to elastically contact the drive bracket when the panel is tilted at a predetermined angle outside the housing, rattle noise during use due to play of the drive bracket can be suppressed.

  The embodiment will be described with reference to the drawings. FIG. 1 is an explanatory view showing the installation location of the on-vehicle panel device according to the first embodiment of the present invention, and FIG. 3 is an explanatory diagram of a rear view corresponding to FIG. 2, FIG. 4 is an explanatory diagram of a bottom view corresponding to FIGS. 2 and 3, and FIG. 6 is a side view explanatory view corresponding to FIG. 5, FIG. 7 is a bottom view explanatory view corresponding to FIGS. 5 and 6, and FIG. FIG. 9 is a side view showing a state immediately before the movable panel in the housed state is protruded outside the housing, and FIG. 9 is a side view showing a state in which the movable panel protrudes out of the housing and is tilted. It is explanatory drawing of.

  In the in-vehicle panel device 1 shown in these drawings, the movable panel 2 can be moved in and out of the housing 3, and the movable panel 2 approaching from the housing 3 is tilted by about 40 degrees (see FIG. 5). It has become. As shown in FIG. 1, the in-vehicle panel device 1 has a housing 3 installed on the back surface of a front seat 30 in a vehicle interior so that the movable panel 2 can protrude above the housing 3. When in use, the movable panel 2 in a tilted posture that protrudes upward from the housing 3 is disposed on the back side of the headrest 31 of the front seat 30. Therefore, the panel device 1 does not get in the way of the passenger compartment, and the passenger in the rear seat can see the display screen 2a of the movable panel 2 in an easy posture when in use.

  The configuration of the in-vehicle panel device 1 will be described. The panel device 1 includes a movable panel 2 and a box-shaped housing that has an opening 3 a for allowing the movable panel 2 to appear and retract and can accommodate the movable panel 2. The body 3, the first chassis 4 and the second chassis 5 fixed in the housing 3, driving means including the motor 6 and the gear group 7 incorporated in the housing 3, and the movable panel 2. A drive bracket 8 that is rotatably connected to the rear end portion and slides in the housing 3, and a boomerang-shaped integrated bracket 9 that is fixed to both side surfaces of the movable panel 2 are provided.

  The movable panel 2 has a display screen 2a composed of a liquid crystal display (LCD) or the like on the front side, and the movable panel 2 can be stored in the casing 3 in a posture substantially parallel to the installation surface of the casing 3. It is. A single-open door 10 is attached to the opening 3 a of the housing 3, and this door 10 is always elastically biased in the closing direction by a torsion spring 11. When the movable panel 2 protrudes outward from the housing 3, the door 10 is pushed open by the movable panel 2 as shown in FIGS. 5 and 9, and the movable panel 2 is stored in the housing 3. As shown in FIG. 2, the door 10 is closed by the urging force of the torsion spring 11, so that the opening 3 a is closed by the door 10. A cushion member 12 made of rubber or the like is attached in the vicinity of the opening 3a in the housing 3.

  The first chassis 4 is disposed to face both side surfaces of the housing 3, and the second chassis 5 is disposed to face the inner side of the first chassis 4. A first guide groove 13 is provided in the first chassis 4, and an engagement pin 9 a provided at the rear end portion of the integrated bracket 9 is inserted into the first guide groove 13 to be slidably engaged. Match. The first guide groove 13 is mainly formed as a broken line-shaped groove in which the parallel guide portion 13a and the inclined guide portion 13b communicate with each other, but the end on the back side of the parallel guide portion 13a is the side where the cushion member 12 exists. It becomes the inclination closed end part 13c of the shape inclined to the opposite side. In addition, the foremost portion (the end portion on the opening 3a side) of the first guide groove 13 communicates with a clearance groove 14 that extends substantially at right angles to the parallel guide portion 13a. On the other hand, the second chassis 5 is provided with a second guide groove 15 extending linearly, and a plurality of engagement pins 8 a provided on the drive bracket 8 are inserted into the second guide groove 15. It is slidably engaged. The parallel guide portion 13 a of the first guide groove 13 extends parallel to the second guide groove 15, but the inclined guide portion 13 b extends inclined with respect to the second guide groove 15.

  In addition, although the groove width of the entrance part of the relief groove 14 is formed so as to be narrow so that the engagement pin 9a of the integrated bracket 9 cannot enter, the groove width of the narrow part can be widened. When an external force is applied, a width dimension is secured such that the engagement pin 9a can enter the escape groove 14.

  The front end portion of the drive bracket 8 and the rear end portion of the movable panel 2 are connected to each other via a support shaft 16 so as to be freely rotatable. The drive bracket 8 is driven by the motor 6 via the gear group 7 and performs a reciprocating linear movement along the second guide groove 15, that is, a sliding movement in the direction of approaching and separating from the opening 3 a in the housing 3. When the drive bracket 8 slides, the rear end portion of the movable panel 2 slides integrally, so that the movable panel 2 is driven by the motor 6 via the drive bracket 8.

  The integrated bracket 9 is formed with a tail-like rearward extending portion 9b projecting obliquely rearward, and an engaging pin 9a is projected from the rearward extending portion 9b. Since the integrated bracket 9 is fixed to the side surface of the movable panel 2, when the rear end portion of the movable panel 2 slides integrally with the drive bracket 8, the engaging pin 9 a of the integrated bracket 9 enters the first guide groove 13. Move while being guided. At this time, when the engaging pin 9a moves while being guided by the parallel guide portion 13a, the integrated bracket 9 does not tilt, so the movable panel 2 slides integrally with the drive bracket 8 without tilting. When the joint pin 9a moves while being guided by the tilt guide portion 13b, the tilt angle of the boomerang-shaped integrated bracket 9 changes, so that the movable panel 2 slides while tilting in the same manner as the integrated bracket 9.

  Next, in the in-vehicle panel device 1, an operation for storing and holding the movable panel 2 in the housing 3 and an operation for projecting the movable panel 2 out of the housing 3 and shifting to a desired tilting posture will be described in detail. To do.

  When not in use, as shown in FIGS. 2 to 4, the movable panel 2 is housed in the housing 3 in a posture substantially parallel to the installation surface of the housing 3 (the back surface of the front seat 30). At this time, the drive bracket 8 is in the innermost position in the housing 3 and the movable panel 2 is immersed in the housing 3, and accordingly, the engagement pin 9 a of the rear extension portion 9 b of the integrated bracket 9 is provided. Since the first guide groove 13 is introduced into the inclined closed end portion 13c at the innermost portion, the distal end portion of the movable panel 2 is in elastic contact with the cushion member 12 near the opening 3a. That is, when the movable panel 2 is stored, the driving pin 8 is driven by driving means such as the motor 6 to slide away from the opening 3a to reach the position shown in FIG. Although it is introduced into the inclined closed end portion 13c, the engaging pin 9a is introduced into the parallel guide portion 13a as shown in FIG. 8 until just before that, so that the movable panel 2 remains in non-contact with the cushion member 12. The second guide groove 15 and the parallel guide portion 13a are maintained in a parallel posture and enter the housing 3. However, when the engaging pin 9a is introduced into the inclined closed end portion 13c, the movable panel 2 is slightly tilted forward in the casing 3, so that the distal end portion of the movable panel 2 is elastically applied to the cushion member 12. Since the movable panel 2 is stored elastically by this, the generation of rattle noise is reliably suppressed (see FIG. 2). However, when the engaging pin 9a of the integrated bracket 9 is not introduced into the inclined closed end portion 13c, the cushion member 12 is separated from the movable panel 2, so that the movable panel 2 moves in and out of the housing 3. There is no possibility that the cushion member 12 sometimes interferes with the movable panel 2.

  When the housed movable panel 2 is projected outward from the housing 3, the drive bracket 8 is slid in the direction close to the opening 3a by the drive means such as the motor 6. Accordingly, the drive bracket 8 first moves from the position shown in FIGS. 2 and 3 to the position shown in FIG. 8, and accordingly, the engaging pin 9a of the integrated bracket 9 is introduced from the inclined closed end portion 13c to the parallel guide portion 13a. Therefore, the movable panel 2 projects outward from the housing 3 while maintaining a posture parallel to the second guide groove 15 and the parallel guide portion 13a. When the drive bracket 8 slides and the engaging pin 9a is introduced from the parallel guide portion 13a to the inclined guide portion 13b, the posture of the integrated bracket 9 gradually changes as the drive bracket 8 slides. As the engaging pin 9a moves toward the opening 3a along the inclined guide portion 13b, the inclination angle of the movable panel 2 increases as shown in FIG. When the drive bracket 8 slides to the foremost position shown in FIGS. 5 and 6, the engaging pin 9a is detached from the inclined guide portion 13b and moved to the foremost portion of the first guide groove 13 (the end portion on the opening 3a side). As a result, the tilt angle of the movable panel 2 becomes maximum (about 40 degrees), and the drive bracket 8 stops. Since the vehicle-mounted panel device 1 is used in this state, the passenger in the rear seat can see the display screen 2a of the movable panel 2 in an easy posture.

  The engaging pin 9a that has reached the forefront portion of the first guide groove 13 is positioned at the entrance portion of the escape groove 14, but as described above, the groove width of the entrance portion of the escape groove 14 is the engagement width. Since the pin 9a is formed so narrow that the pin 9a cannot enter and has a narrow portion, there is no possibility that the engagement pin 9a may accidentally enter the escape groove 14, and therefore the movable panel 2 is held in a desired tilted posture. Is done. However, when an excessive external force is applied to the movable panel 2 from the headrest 31 side, the engaging pin 9a can pass through the narrow portion and enter the escape groove 14 by the external force. Even if the headrest 31 collides with the movable panel 2, the impact is alleviated.

  When the movable panel 2 in the tilted position shown in FIGS. 5 to 7 is housed in the housing 3 again, the motor 6 is rotated in the reverse direction to slide the drive bracket 8 away from the opening 3a. Just do it. At that time, as the engaging pin 9a of the integrated bracket 9 moves to the inner side of the housing 3 along the inclined guide portion 13b, the tilt angle of the movable panel 2 decreases, and the engaging pin 9a When it is introduced into the parallel guide portion 13a, the tilt angle of the movable panel 2 becomes zero. When the engaging pin 9a is introduced from the parallel guide portion 13a to the inclined closed end portion 13c, the drive bracket 8 stops and the movable panel 2 returns to the housed state shown in FIGS.

  As described above, in the in-vehicle panel device 1 according to the present embodiment, the integrated bracket 9 is fixed to the movable panel 2 driven by the motor 6 via the drive bracket 8, and the integrated bracket 9 extends rearward. Since the engaging pin 9 a provided on the protruding portion 9 b is slidably engaged with the first guide groove 13 in the housing 3, the engaging pin 9 a is introduced into the inclined guide portion 13 b of the first guide groove 13. When the drive bracket 8 is slid while being moved, the tilt angle of the movable panel 2 changes as the posture of the integrated bracket 9 changes. Therefore, the movable panel 2 can be protruded from the housing 3 while being tilted to be shifted to a desired tilting posture, and a simple structure that does not require the rotation arm to be connected to the movable panel 2 is realized. As a result, the on-vehicle panel device 1 has significantly improved design as compared with the structure in which the rotating arm is exposed when in use, and can avoid play caused by the rotating arm, thereby improving the quality and the rattle noise. Can be expected to be reduced.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Here, FIG. 10 is an explanatory view in a side view showing a state in which the movable panel is housed in the in-vehicle panel device according to the second embodiment, and FIG. 11 is a panel device that causes the movable panel to protrude in a desired tilting posture. FIG. 12 is an explanatory diagram of a main part showing a pair of lever members in FIG. 11, and FIG. 13 is an explanatory diagram of an essential part in a top view corresponding to FIG. The parts corresponding to those in FIGS. 1 to 9 are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIGS. 10 to 13, in the in-vehicle panel device 20 according to the second embodiment, the front part in the housing 3 can be rotated around a common support shaft 23 outside the first chassis 4. A first lever member 21 and a second lever member 22 which are held and spring-biased in a direction away from each other are provided, which is greatly different from the first embodiment described above. Although not shown, the first and second lever members 21 and 22 have built-in torsion springs that elastically contact opposite inner wall surfaces, and the torsion springs push both lever members 21 and 22 apart. It is spring-biased. Further, by bringing the stopper portion 21a of the first lever member 21 and the stopper portion 22a of the second lever member 22 into contact with the restriction pin 24, the lever members 21 and 22 are arranged at predetermined positions, respectively. Yes.

  The first lever member 21 is disposed in the vicinity of the entrance of the escape groove 14 communicating with the foremost portion (the end portion on the opening 3a side) of the first guide groove 13, The engagement pin 9a slidably engaged with the one guide groove 13 is prevented from entering the escape groove 14. However, in the second embodiment, the groove width of the entrance portion of the relief groove 14 is not particularly narrow, so that if the force against the urging force of the first lever member 21 is applied, the engagement pin 9a is It is possible to enter the escape groove 14.

  Therefore, as shown in FIG. 11, when the movable panel 2 protrudes in a desired tilting posture, when an excessive external force is applied to the movable panel 2 from the headrest side, or the movable panel 2 is forced from the rear seat side. When an external force such as pulling forward acts on the movable panel 2, the movable panel 2 can be rotated while the engaging pin 9 a enters the escape groove 14, and therefore, a damage accident caused by this type of external force is less likely to occur. ing. Further, when this kind of external force is removed, the engagement pin 9a can be pushed back from the escape groove 14 to the first guide groove 13 by the biasing force of the first lever member 21, so that it automatically returns to the original use state. It becomes possible to make it.

  On the other hand, the distal end bending portion 22 b of the second lever member 22 is disposed at a position passing through the window portion 4 a of the first chassis 4 and adjacent to the second guide groove 15 of the second chassis 5. As shown in FIG. 11, when the movable panel 2 protrudes in a desired tilting posture, the distal end bending portion 22b of the second lever member 22 is in elastic contact with the engagement pin 8a of the drive bracket 8, so that the drive bracket The rattle noise at the time of use resulting from the play of 8 can be suppressed.

  In each of the above embodiments, the in-vehicle panel devices 1 and 20 in which the housing 3 is installed on the back surface of the front seat 30 in the vehicle interior have been described. However, the housing is installed in another location (for example, a ceiling surface) in the vehicle interior.
