Description

  The present invention is applied to an audio device or a navigation device mounted on a vehicle, and relates to a panel device in which panel units such as a display panel unit and an operation panel unit that can take a plurality of postures are arranged on the front surface of a casing.

  Some audio devices and navigation devices mounted on a vehicle have a structure in which a display panel unit capable of taking a plurality of inclined postures is arranged on the front surface of a housing. For example, the casing is installed in the instrument panel so that the display panel unit is exposed in the vehicle compartment. In such an audio device and navigation device, the display panel unit is inclined at an angle that is easy for the occupant to see. Usually, since the occupant's line of sight is higher than the display panel, the display panel unit is inclined backward. It is made to lean backward.

  In recent years, there are vehicles in which the tilt angle of the instrument panel is increased due to the design of the passenger compartment. In an audio device or a navigation device in which a casing is installed in the instrument panel of such a vehicle, the casing is not in a backward tilted position in order to align the display panel unit with the eyes of the occupant from above. In some cases, it may be necessary to adopt a forward leaning posture inclined forward. In the panel device that must be installed in the vehicle in this way, a mechanism is required for causing the display panel unit disposed on the front surface of the casing to be tilted forward.

Thus, a panel device having a mechanism for causing the display panel unit to lean forward is proposed (see Patent Document 1). In this conventional panel device, the display panel unit is supported by pulling a lower part of the display panel unit supported rotatably at predetermined positions on both side surfaces into the main body (housing). I try to lean forward.

The arm member will advance. Then, in the process in which the arm member is advanced, the pin of the arm member is the first of the upper and lower guide portions of the slide member guide portion formed on the slide member that is advanced and slid and the bracket guide portion formed on the bracket. It is guided upward by both of the inclined movement guide portions. As a result, the arm member moves forward and the second end moves upward, and the first end on the opposite side of the arm member according to the movement of the second end (on the first fulcrum) The panel unit can be rotated about the first fulcrum portion to have a forward inclined posture inclined forward with respect to the housing.

  Further, in the panel device according to the present invention, the bracket guide portion is configured to lower the pin guided by the upper and lower guide portions that advance with the sliding movement of the slide member from the first position to the second position. A second inclined movement guide portion for guiding, and the upper and lower guide portions of the slide member guide portion and the second inclined movement guide portion of the bracket guide portion function as the panel backward inclination posture driving portion of the arm driving mechanism. It can be set as the structure to do.

  With such a configuration, the pin provided at the second end portion of the arm member is restricted from relative movement in the front-rear direction with respect to the slide member by the upper and lower guide portions of the slide member guide portion. The arm member further advances along with the advance slide to the second position. Then, in the process in which the arm member is advanced, the pins of the arm member are the upper and lower guide portions of the slide member guide portion formed on the slide member that is advanced and slid and the second of the bracket guide portion formed on the bracket. It is guided downward by both of the inclined movement guide portions. As a result, the arm member moves forward while the second end moves downward, and the first end on the opposite side of the arm member according to the movement of the second end (on the first fulcrum) The panel unit can be rotated about the first fulcrum portion and can be in a rearward tilted posture tilted rearward with respect to the housing.

  Further, in the panel device according to the present invention, the bracket guide portion includes a front / rear restricting portion that restricts movement of the pin in the front / rear direction, and the slide member guide portion is a pin that is restricted from moving in the front / rear direction. Has a front / rear guide portion that guides sliding so as not to prevent the sliding movement of the slide member, and the front / rear guide portion of the slide member guide portion and the front / rear restricting portion of the bracket guide portion of the arm drive mechanism It can be set as the structure which functions as the said panel opening drive part.

  With such a configuration, the movement of the pin provided in the second end portion of the arm member in the front-rear direction is restricted by the restriction portion of the bracket guide portion formed on the bracket. As a result, the forward movement of the second fulcrum portion of the panel unit that is rotatably engaged with the first end portion of the arm member is restricted. In this state, in the process in which the first fulcrum is pushed forward by the further advancement slide of the slide member, the pin whose movement in the front-rear direction is regulated does not interfere with the advancement slide of the slide member. Since the guide is guided, the second fulcrum portion in a state in which the forward movement is restricted can follow the advancement of the first fulcrum portion, whereby the panel unit further falls and the front surface of the housing It can be an open posture to release.

  According to the panel device of the present invention, when the slide member advances and slides, the panel unit moves forward and takes a forward leaning posture due to the movement of the arm member accompanying the advance and slide. A mechanism for retracting the lower end of the panel unit is not required. Therefore, it is not necessary to move the member (mechanism) for drawing the lower end of the panel unit to the back of the casing, and it is not necessary to extend the depth of the casing for the member (mechanism). Therefore, it becomes possible to assume a forward tilt posture in which the panel unit is tilted forward on the front surface of the housing without increasing the size as much as possible.

Then, when maintaining the forward tilting posture of the display panel unit 10, the control circuit 70 cuts off the power supply to the motor 50 when recognizing that the slide member 30 is in the first position.

  When power is continuously supplied from the control circuit 70 to the motor 50, the motor 50 further rotates forward from the state in which the display panel unit 10 is in the forward inclined posture, and the slide member 30 further advances and slides. Then, as shown in FIG. 11, the relative movement in the front-rear direction with respect to the slide member 30 is still restricted by the upper and lower guide grooves 301 of the slide guide groove 300 formed in the slide member 30 with the terminal pins 63 a and 63 b of the arm members 40 a and 40 b. In this state, the arm members 40a and 40b further advance as the slide member 30 advances and slides. As the arm members 40 a and 40 b advance, the terminal pins 63 a and 63 b of the arm members 40 a and 40 b move from the upper and lower guide grooves 301 of the slide member guide groove 300 and the apex guide groove portion 202 of the bracket guide groove 200. The second inclined movement guide groove 203 is guided downward.

  As a result, the arm members 40a and 40b move forward while the second ends provided with the terminal pins 63a and 63b move downward, and the arm members 40a and 40b corresponding to the movement of the second ends are moved. The display panel unit 10 is pulled back through the second support pins 62a and 62b provided at the first end by the movement of the second end opposite to 40b. As a result, the display is performed centering on the first support pins 61a and 61b (first fulcrum portions) that rotatably connect the front end portions of the slide side standing plates 33a and 33b of the slide member 30 to the side portions of the display panel unit 10. Contrary to the case described above (see FIG. 9), the panel unit 10 rotates so as to incline backward.

  Then, the slide member 30 advances and slides to a predetermined position (second position), and the terminal pins 63a and 63b are formed between the upper and lower guide groove portions 301 and the horizontal guide groove portion 302 of the slide member guide groove 300 as shown in FIG. After reaching the boundary part and reaching the boundary part between the second inclined movement guide groove part 203 and the movement restriction guide groove part 204 of the bracket guide groove 200, the display panel unit 10 is inclined backward by a predetermined angle with respect to the housing 110. Inclined posture (see FIG. 3). The control circuit 70 further recognizes the advance position (second position) of the slide member 30, that is, the backward tilt posture of the display panel unit 10 based on the rotation amount signal output from the rotation sensor 56. When maintaining the backward tilting posture of the display panel unit 10, the control circuit 70 cuts off the power supply to the motor 50 when recognizing that the slide member 30 is in the second position.

  When power is continuously supplied to the motor 50 from the control circuit 70, the motor 50 further rotates forward from the state where the display panel unit 10 is in the backward tilted posture, and the slide member 30 further advances and slides. Then, as shown in FIG. 13, the terminal provided in the 2nd end part of arm member 40a, 40b by the control part 204 of the bracket guide groove 200 formed in bracket 20a, 20b (bracket side standing board 22a, 22b). Since the movement of the pins 63a and 63b in the front-rear direction is restricted, the movement (advance) of the arm members 40a and 40b is restricted. As a result, the forward movement of the second support pins 62a and 62b that rotatably couple the first ends of the arm members 40a and 40b to the sides of the display panel unit 10 is restricted. In this state, in the process in which the first support pins 61a and 62 are pushed out by the further advancement slide of the slide member 30, as shown in FIGS. Terminal pins 63a, 63b provided at the second ends of the arm members 40a, 40b so that the second support pins 62a, 62b, which are restricted from moving toward the first member, follow the first support pins 61a, 61. It is slidably guided by the horizontal guide groove 302 of the slide member guide groove 300 formed in the slide member 30 (slide guide side upright plates 33a and 33b). Thus, as the slide member 30 advances and slides, the arm members 40a and 40b are provided with the second support pins 62a and 62b around the second ends provided with the terminal pins 63a and 63b. The display panel unit 10 is further tilted by rotating so that the end portion moves downward.

  Then, in the process in which the first support pins 61a and 61b are further pushed out by the further advancement slide of the slide member 30, the second advancement without disturbing the advancement slide of the slide member 30, as shown in FIGS. Terminal pins 63a and 63b provided at the second ends of the arm members 40a and 40b are further formed on the slide member 30 so that the support pins 62a and 62b are driven with respect to the first support pins 61a and 61b. It is slidably guided by the inclined guide portion 302 of the slide member guide groove portion 300. Thereby, as the slide member 30 moves forward, the arm members 40a and 40b are provided with the second support pins 62a and 62b provided around the second end portion provided with the terminal pins 63a and 63b. The display panel unit 10 is further tilted by rotating so that one end portion moves downward.

  Then, as shown in FIGS. 7 and 8, the slide member 30 advances and slides to the most advanced position, and the terminal pins 63a and 63b provided at the second ends of the arm members 40a and 40b are the slide member guide groove portions. When guided to the terminal guide groove 304 of 300, the limit of following of the first support pins 61a and 61b of the second support pins 62a and 62 provided at the first ends of the arm members 40a and 40b is reached. At this time, the protrusion 321 formed on the slide member 30 (side sliding plate 32b) pushes the second position detection switch 74, and the second position detection switch 74 is turned on. As a result, the control circuit board 70 cuts off the power supply to the motor 50, and the motor 50 stops. In this state, the display panel unit 10 assumes an open posture in which the escutcheon 111 of the housing 110 is opened (see FIG. 4). The control circuit 70 that cuts off the power supply to the motor 50 by the ON operation of the second position detection switch 74 recognizes that the display panel unit 10 is in the open posture based on the ON operation of the second position detection switch 74. ing.

  According to the panel device according to the embodiment as described above, when the slide member 30 advances and slides, the display panel unit 10 and the front panel are tilted forward by the movement of the arm members 40a and 40b accompanying the advance and slide. Since it is in a posture (see FIGS. 5, 6, 9, and 10), a mechanism for pulling the lower end portion of the display panel unit 10 into the housing 110 as in the prior art is not required. Therefore, it is not necessary to move a member (mechanism) for pulling the lower end portion of the display panel unit 10 to the back of the housing 110, and it is not necessary to extend the depth of the housing 110 for that member. Therefore, the display panel unit 10 can be placed in a forward tilted posture in which the display panel unit 10 is tilted forward on the front surface of the housing 110 without increasing the size of the device (housing 110).

  Further, by continuing the sliding movement of the slide member 30, the display panel unit 10 is sequentially tilted backward (see FIG. 12) and opened to open the front surface of the housing 110 (see FIG. 7). FIG. 8).

  When the slide member 30 is slid back into the housing 110, each part is driven in the opposite direction as described above. As a result, the display panel unit 10 is moved from the open position to the backward tilt position, the forward tilt position, and the standing position. The posture is changed in the order of the posture.

  The panel device 100 as described above is installed in an instrument panel 500 of a vehicle, for example, as shown in FIGS. That is, as shown in FIG. 17, the display screen 10a of the display panel unit 10 in the standing posture (see FIG. 1) is placed in the instrument panel 500 having a relatively large tilt angle so that the display screen 10a is aligned with the surface of the instrument panel 500. A body 110 is installed. When the occupant uses the display panel unit 10, as shown in FIG. 18, the display panel unit 10 moves forward with respect to the housing 10 in order to match the occupant's eyes from above (see the broken line block arrow). An inclined forward leaning posture is adopted. As a result, the occupant can easily visually recognize the information displayed on the display screen 10a by looking from above. Note that when the disk D is inserted into a disk device (not shown) provided in the housing 110 or when the disk D is ejected, the display panel unit 10 is brought into an open posture as shown in FIG. . As a result, the disc insertion slot 112 formed in the escutcheon 111 of the housing 110 is exposed (see FIG. 4), and in this state, the disc D is inserted into the disc insertion slot 112 obliquely from above, or It is discharged obliquely upward.
