Description

  The present invention relates to a display panel device used for an in-vehicle audio device, an in-vehicle navigation device, and the like.

  Conventionally, a display panel device capable of panning and tilting a display panel has been proposed (see, for example, Patent Document 1). This display panel device is used, for example, in an in-vehicle audio device, and the tip of each of a pair of sliders that can move in the front-rear direction of the device body (housing) is pivotally coupled to the lower part of the back surface of the display panel. (An angle is variable), and the other end portion of the support arm whose one end portion is rotatably attached in the apparatus main body has a structure in which the upper part of the back surface of the display panel is pivot-supported (the angle is variable).

In such a display panel device, the pair of sliders are individually moved back and forth to change the upward angle of the display panel pivotally supported at the tip of the support arm (tilt operation), or to change the horizontal angle thereof. You can change (pan operation).
JP 2003-69920 A

  However, in the above-described conventional display panel device, the display panel is pivotally supported at one point of the end of the support arm, and the other two points of the display panel are pushed and pulled by the slider, whereby the upward angle and the horizontal angle of the display panel are pulled. Therefore, the support of the display panel is likely to be unstable, and thus a display panel that is particularly heavy is likely to be affected by external vibration. In this respect, it is not preferable to mount the conventional display panel device on a vehicle having a poor vibration environment.

  Further, in the conventional display panel device, the display panel pivotally supported at one point of the other end of the support arm whose one end is fixed to the device main body (housing) is pressed against the other two points, and the posture of the display panel is pulled. Therefore, the allowable posture and position of the display panel are limited. For example, since some torque is always generated at the pivot support point by the support arm by pushing and pulling the display panel at two points, the display panel cannot be moved back and forth in a state where the display panel is maintained in a fixed posture. Further, for example, the display panel cannot be tilted so that its display surface faces downward (downward tilt).

  The present invention has been made to solve such a conventional problem, and enables more stable support of the display panel unit and allows the display panel unit to take more postures. A display panel device is provided.

  With such a configuration, the display panel unit is supported by the panel support member so as to be rotatable with respect to the axis along one end thereof, so that the shaft support of the display panel unit is not a point support like a pivot support. It becomes possible. If the panel support member, the first shaft body, and the second shaft body are evenly moved in the front-rear direction by the main movement mechanism, the first sub movement mechanism, and the second sub movement mechanism, the display panel unit is It moves in the front-rear direction while maintaining the posture.

The display panel unit rotates together with the panel support member by the pushing operation with respect to and the pulling operation of the second shaft body with respect to the back surface of the display panel unit. On the other hand, when the first shaft is moved rearward by the first sub-moving mechanism and the second shaft is moved forward by the second sub-moving mechanism, the back surface of the display panel unit of the first shaft The display panel rotates together with the panel support member in the opposite direction to that described above by the pulling operation with respect to and the pressing operation of the second shaft body on the display panel unit.

  Further, in the display panel device according to the present invention, the display panel unit is provided at each of both end portions sandwiching the rotation axis of the panel support member on the back surface thereof and extends along the end portion. Each of the first shaft body and the second shaft body has a ball body formed at a tip portion, and the ball body is formed in a pivot receiving groove of the guide member. It can be set as the structure fitted so that sliding is possible.

  With such a configuration, the first shaft body and the second shaft slidably pivotally coupled in the direction along the both end portions with the rotation axis of the panel support member on the back surface of the display panel unit sandwiched therebetween. The shaft body can be specifically realized.

  Further, in the display panel device according to the present invention, the pivot receiving groove formed in the guide member has a sliding surface having a shape corresponding to the ball body and is open to the outside through the open slit portion. The open slit portion is tapered outward from the pivot receiving groove, and one of the first shaft body and the second shaft body passes through the open slit portion and has a tip portion thereof. It can be set as the structure by which the said ball body formed in this is inserted in the said pivot receiving groove.

Will come to be. While the ball body is supported so as not to be detached from the pivot receiving groove, the shaft body and the open slit portion do not interfere at all during the pivot operation (pan operation of the display panel unit).

  Furthermore, in the display panel device according to the present invention, the guide member may be formed of an elastic body.

  With such a configuration, the ball body can be fitted into the pivot receiving groove of the guide member very tightly. As a result, the ball body can slide in the pivot receiving groove with very little play. .

  Note that a synthetic resin having lubricity such as silicon resin or polyacetal resin (POM) can be used as the elastic body forming the guide member.

And a drive mechanism for moving the sub-slide member in the front-rear direction.

  With such a configuration, it is possible to specifically realize the first sub-movement mechanism that moves the first shaft body in the front-rear direction and the second sub-movement mechanism that moves the second shaft body in the front-rear direction. It becomes like this.

  According to the display panel device of the present invention, the display panel unit is not pivotally supported but is pivotally supported by the panel support member at one end thereof so that the display panel unit can tilt in the front-rear direction around the axis along the one end. In addition, since the display panel unit can be rotated in the left-right direction together with the panel support member, the display panel unit can be supported more stably and the display panel unit can be placed in more postures. become.

  The first shaft body 60a is mounted on the bracket portion 52a of the slide plate 51a in the first sub moving mechanism 50a, and the second shaft body 60b is mounted on the bracket portion 52b of the slide plate 51b in the second sub moving mechanism 50b. Is installed. The first shaft body 60a (second shaft body 60b) includes a mounting plate 61a (61b), a shaft portion 62a (62b) protruding from one end surface of the mounting plate 61a (61b), and a shaft portion 62a ( 62b) is provided with a ball body 63a (63b) fixed to the tip. Then, the mounting plate 61a (61b) is fixed to the bracket portion 52a (52b) of the slide plate 51a (51b) by screwing or the like, and the ball body 63a (63b) fixed to the tip of the shaft portion 62a (62b) slides. It protrudes further forward from the tip of the plate 51a (51b).

  The panel support bracket 20 that supports the display panel unit 10 so as to be rotatable (rotation axis Ay) is supported by the support plate 32 of the main slide plate 31 so as to be rotatable (rotation axis Az). The ball body 63a of the shaft body 60a is slidably fitted into the pivot receiving groove 111a of one guide member 11a provided on the back surface of the display panel unit 10, and the ball body 60b of the second shaft body 60b is slidably mounted on the display panel unit. 10 is slidably fitted in a pivot receiving groove 111b of the other guide member 11b provided on the back surface of the guide member 11b. That is, the ball body 63a of the first shaft body 60a and the ball body 63b of the second shaft body 60b are disposed at both end portions sandwiching the rotation axis (Az) of the panel support bracket 30 of the display panel unit 10. The guide members 11a and 11b are pivotally coupled to each other.

  As shown in FIG. 2A, the guide member 11a (guide member 11b) is formed with a pivot receiving groove 110a (110b) extending in the vertical direction with a spherical inner surface in a substantially rectangular parallelepiped block. The pivot receiving groove 110a (110b) is structured to open outward through the opening slit portion 111a (111b). The open slit 111a (111b) extends in a taper shape outward from the pivot receiving groove 110a (110b) (see FIG. 2B). As shown in FIGS. 2B and 2C, the shaft portion 62a (62) extending from the mounting plate 61a (61b) of the first shaft body 60a (second shaft body 60b) is an open slit portion 111a. The ball body 63a (63b) at the tip is inserted into the pivot receiving groove 110a (110b). As a result, the first shaft body 60a (second shaft body 60b) has a movement component in the AA ′ direction shown in FIG. 2B with the ball body 63a (63b) as a fulcrum, and FIG. Pivoting motion having a movement component in the BB ′ direction shown in FIG. 2 is possible, and the ball body 63a (63b) slides in the pivot receiving groove 110a (110b) (CC ′ direction shown in FIG. 2C). Movement).

  The guide member 11a (11b) and the ball body 63a (63b) may be made of metal, but the guide member 11a (11b) is an elastic body having lubricity such as silicon or polyacetal resin (POM). There may be. Thus, when the guide member 11a (11b) is formed of an elastic body, the ball body 63a (63b) can be fitted into the pivot receiving groove 110a (110b) very tightly (for example, the ball body 63a ( The inner diameter of the pivot receiving groove 110a (110b) can be slightly smaller than the diameter of 63b). As a result, the ball body 63a (63b) is in a state where there is very little play in the pivot receiving groove 110a (110b). It becomes slidable. Further, the shaft portion 62a (62b) hits the wall surface of the open slit 111a (111b) by a pivoting operation (a panning operation of the display panel unit 10 described later) in the pivot receiving groove 110a (110b) of the ball body 63a (63b). Even if that happens, the perceived sound is extremely low (prevention of abnormal noise).

  The display panel unit 10 supported by the panel support bracket 20 so as to be rotatable about the horizontal support shafts 12a and 12b (axis Ay) is disposed on the front side of the device main body 100 as shown in FIG. A first moving body 30 for moving back and forth, and a first shaft body 60a and a second shaft body 60b, which are slidably pivotally coupled to guide members 11a and 11b fixed to the display panel unit 10, for moving back and forth. The sub movement mechanism 50 a and the second sub movement mechanism 50 b are provided on the bottom plate of the apparatus main body 100.

  The control system for driving the display panel unit 10 is configured as shown in FIG. 4, for example. In FIG. 4, the control circuit 200 is configured to control the drive motor 37 of the main moving mechanism 30 and the first sub moving mechanism 50a based on operation signals from the front / rear operation key 210 and the pan / tilt operation key 220 operated by the user. Drive control of the drive motor 57a and the drive motor 57b of the second sub moving mechanism 50b is performed. The control circuit 200 is configured on a circuit board (not shown), and the circuit board is installed inside the apparatus main body 100. Further, the front / rear operation key 210 and the pan / tilt operation key 220 may be provided on the front surface of the display panel unit 10 or may be provided on the remote control operation unit. When provided in the remote control operation unit, operation signals from the front / rear operation key 210 and the rotation operation key 220 are provided to the control circuit 200 by radio.

  The front / rear operation key 210 has a front movement key 211 and a rear movement key 212. When the front movement key 211 is operated, a control signal for moving the display panel unit 10 forward is output, and when the rear movement key 212 is operated, a control signal for moving the display panel unit 10 backward is output. . The pan / tilt operation key 220 includes an upper tilt key 221, a lower tilt key 223, a right pan key 222, and a left pan key 224. When the upper tilt key 221 is operated, a control signal for directing the display surface of the display panel unit 10 upward is output, and when the lower tilt key 223 is operated, the display screen of the display panel unit 10 is directed downward. When the right pan key 222 is operated, a control signal for rotating the display panel unit 10 in the clockwise direction and directing the display surface to the left when viewed from the user is output. When the left pan key 224 is operated, a control signal for rotating the display panel unit 10 counterclockwise and directing the display screen to the right when viewed from the user is output.

  In the display panel device as described above, the display panel unit 10 can be driven as follows.

  For example, when the forward movement key 211 of the forward / backward operation key 210 is operated, the control circuit 200 causes the main slide plate 31 of the main movement mechanism 30, the first sub movement mechanism based on the control signal from the front movement key 211. The drive motors 37, 57a, and 57b are driven so that the slide plates 51a and 51b of the second sub moving mechanism 50b and the second sub moving mechanism 50b are simultaneously advanced (no relative movement). Due to the synchronized forward movement of the main slide plate 31 and the slide plates 51a and 51b, the display panel unit 10 moves forward while maintaining a posture (for example, an upright posture). On the other hand, when the rear movement key 212 is operated, the control circuit 200 simultaneously retracts the main slide plate 31 and the slide tables 51a and 51b based on the control signal from the rear movement key 212 (no relative movement). The drive motors 37, 57a and 57b are driven. As the main slide plate 31 and the slide plates 51a and 51b are moved backward in synchronization with each other, the display panel unit 10 moves backward while maintaining the posture.

  When the left pan key 224 of the pan / tilt operation key 220 is operated, the control circuit 200 stops the main slide plate 31 of the main moving mechanism 30 based on a control signal from the left pan key 224. The drive motors 57a and 57b are driven so that the slide plate 51a of the first sub movement mechanism 50a is moved backward and the slide plate 51b of the second sub movement mechanism 50b is moved forward (the drive motor 37 is stopped). Then, the end portion on the fixed side of the guide member 11a to which the ball body 63a of the first shaft body 60a of the display panel unit 10 is pivotally coupled is pulled rearward, and the second shaft body 60b of the display panel unit 10 is pulled back. The end of the guide member 11b to which the ball body 63b is pivotally connected is pushed forward. Accordingly, as shown in FIG. 5A, the panel support bracket 20 is centered on the vertical support shaft 40 (Az) so that the display screen of the display panel unit 10 is directed to the right (R) side when viewed from the user. Turn counterclockwise (left pan operation).

  On the other hand, when the right pan key 222 is operated, the control circuit 200 stops the main slide plate 31 of the main moving mechanism 30 based on the control signal from the right pan key 222, and the first sub moving mechanism 50a. The drive motors 57a and 57b are driven so that the slide plate 50a of the second sub-movement mechanism 50b moves backward and the slide plate 51b of the second sub-movement mechanism 50b moves backward (the drive motor 37 is stopped). Then, contrary to the case described above, the end portion on the fixed side of the guide member 11a to which the ball 63a of the first shaft body 60a of the display panel unit 10 is pivotally coupled is pushed forward, and the display panel unit The end portion on the fixed side of the guide member 11b to which the ball body 63b of the ten second shaft body 60b is pivotally coupled is pulled backward. Accordingly, as shown in FIG. 5B, the panel support bracket 20 is centered on the vertical support shaft 40 (Az) so that the display screen of the display panel unit 10 faces the left (L) side as viewed from the user. Turn clockwise (right pan operation).

  Further, when the lower tilt key 223 is operated on the pan / tilt operation key 220, the control circuit 200 moves the main slide plate 31 of the main moving mechanism 30 backward based on the control signal from the lower tilt key 223, and the first The drive motors 37, 57a, and 57b are driven so that the slide plates 51a and 51b of the second sub-movement mechanism 50a and the second sub-movement mechanism 50b are simultaneously advanced. Then, the panel support bracket 20 that supports the lower end portion of the display panel unit 10 so as to be freely rotatable (corresponding to the rotation axis Ay: corresponding to the horizontal support shafts 12a and 12b) is pulled rearward, and both side end portions of the display panel unit 10 are supported. The ball body 63a of the first shaft body 60a and the ball body 63b of the second shaft body 60b, which are slidably pivotally coupled to the guide members 11a and 11b fixed to the front, advance. Thereby, as shown in FIG. 6A, the display panel unit 10 is centered on the horizontal support shafts 12a and 12b (axis Ay) so that the lower end of the display panel unit 10 is retracted and the display surface faces downward. To rotate (down tilt operation).

  On the other hand, when the upper tilt key 221 is operated, the control circuit 200 advances the main slide plate 31 of the main moving mechanism 30 based on the control signal from the upper tilt key 221, and also the first sub moving mechanism 50a and the first sub moving mechanism 50a. The drive motors 37, 57a, and 57b are driven so that the slide plates 51a and 51b of the second sub moving mechanism 50b are simultaneously retracted. Then, the panel support bracket 20 that rotatably supports the projecting end portion of the display panel unit 10 is pushed forward, and fixed to both side end portions of the display panel unit 10 but is slidable on the moving members 11a and 11b. The ball body 63a of the first shaft body 60a and the ball body 63b of the second shaft body 60b, which are pivotally coupled to each other, retreat. Accordingly, as shown in FIG. 7, the display panel unit 10 rotates about the horizontal support shafts 12a and 12b (axis Ay) so that the lower end of the display panel unit 10 moves forward and the display surface faces upward. Move (up tilt operation).

  Even if the direction (Ay) of the horizontal support shafts 12a and 12b of the display panel unit 10 changes variously (Ay1, Ay2, etc. in FIG. 1) due to the pan operation of the display panel unit 10 by the rotation of the panel support bracket 20, the display described above. The panel unit 10 can be tilted. Even if the tilt (tilt angle) of the display panel unit 10 supported by the panel support bracket 20 varies in various ways, the panel support bracket 20 is rotated as described above. The pan operation of the display panel unit is possible. Therefore, for example, as shown in FIG. 8A, the display panel unit 10 positioned in front of the device main body 100 operates so that its display surface faces upward and to the left as viewed from the user (upper tilt operation + right (Pan operation) or as shown in FIG. 8 (b), the display surface can be moved downward and to the right as viewed from the user (down tilt operation + left pan operation).

  In the display panel device as described above, the display panel unit 10 is supported by the panel support bracket 20 so as to be rotatable with respect to the horizontal support shafts 12a and 12b at the lower end portions thereof. Since the main slide plate 31 is rotatably supported with respect to a direction Az orthogonal to both the direction (Ay) and the front-rear direction (Ax) of the support shafts 12a and 12b, the change in the attitude of the display panel unit 10 This allows more stable support while allowing In addition, the main support mechanism 20 is moved back and forth by the main moving mechanism 30, and the first shaft body 60 a and the second shaft body slidably pivotally coupled to the guide members 11 a and 11 b provided at both end portions of the display panel unit 10. Since the back-and-forth movement of the shaft body 60b can be individually controlled, the display panel unit 10 can be placed in more postures.
