Be energized.

The operation of the above-configured in-vehicle monitor device will be described in detail. In the storage position illustrated in FIG. 2, the display 10 is in the lying position in which the screen 13 faces downward, and is completely stored in the housing 20, that is, in the dashboard 1. At this time, the lid 1a of the dashboard 1 is closed by the urging force of a spring (not shown), and is still out of contact with the roller 12 of the display 10. Slide base 40
Is at the position shown in FIG. 9 (behind the display 10),
The display 10 is linked to the link member 80 by a tension spring 91.
Is biased in a direction to hold the storage position. Thereby, even if vibration occurs in the vehicle, the display 10 does not rattle, and generation of unpleasant noise can be prevented.

When a predetermined display projecting operation is performed, a control circuit (not shown) rotates the motor 62 in the forward direction,
The rotation is transmitted to the left and right pinions 65 via the worm wheel 63, the gear member 64, and a reduction gear mechanism (not shown), and the slide base 40 starts moving in the direction B of FIG. I do. The movement of the slide base 40 is guided by the guide grooves 51 b of the rack member 51 and the guide grooves 32 of the cam member 30. Elongate hole 42a with movement of slide base 40
The end face of FIG. 9 is the cam follower 11 of the display 10.
a, the cam follower 11a moves inside the cam groove 31 while moving upward through the long hole 42a. Along with this, the display 10 rises while moving as shown in FIG.
The posture of the display 10 at each position is determined by the shape of the cam groove 31 and the connection position of the link member 80.

When the display 10 rises, the roller 1
2 comes into contact with the lower surface of the lid 1a and pushes it open while rolling on the lid 1a. The display 10 rises smoothly until it reaches the state shown in FIG. 5 through the states shown in FIGS. 2 to 3 and 4 in order, and assumes the upright posture in the state shown in FIG. 5, and at this time, the lid 1a is in the most opened state. Thereafter, the display 10 falls down in the opposite direction. At this time, as shown by a two-dot chain line in FIG. 5, the top of the display 10 (portion where the roller 12 is provided) moves substantially parallel to the lid 1a in the open position. The lid 1a does not move in the closing direction even if the display 10 falls down since the shape of the cam groove 31 is determined so as to perform the operation. As a result, it is as if the display 10 is moving independently of the lid 1a, and the sense of quality is not lost.

When the state shown in FIG. 6 is reached, the slide base 40 is positioned at the forefront, the operating member turns on the position detection switch, and in response to this, the control circuit stops the motor 62. When the operation for storing the display 10 is performed after use, the motor 62 is rotated in the reverse direction, and the display 10 is driven to the storage position by the reverse operation. At that time, the lid 1a does not move until the display 10 stands upright,
Thereafter, the display 1 is driven by the urging force of a spring (not shown).
It closes following the storing operation of 0.

As described above, in the present embodiment, since the roller 12 that rolls on the lid 1a is provided on the display 10, the lid 1a can be opened and closed smoothly and the generation of sliding noise can be prevented. . Also, lid 1
Since the contact portion 12b of the roller 12 that rolls on the lower surface of the a is made of rubber, the vehicle vibrates while the display 10 is moving or in use, and the roller 12 hits the lid 1a. Can be minimized. Also,
Since the roller 12 is pressed in one direction by the compression spring, the roller 12 itself does not rattle and the generation of low-pitched sound is suppressed.

Further, by the action of the spring 91, generation of sound due to rattling of the display 10 can be suppressed. That is, when the display 10 is driven from the storage position to the use position, the link member 80 initially rotates counterclockwise in the drawing counterclockwise against the urging force of the spring 91 so that the display 10 stands upright. Thereafter, it rotates clockwise, that is, in the biasing direction of the spring 91. Therefore, the display 10 is urged toward the storage position by the spring 91 until the display 10 stands upright from the storage position, but is urged toward the use position by the same spring 91 after standing upright. Therefore, even at the use position, the display 10 does not rattle due to the vibration of the vehicle, and the generation of unpleasant noise can be prevented.

In the above embodiment, the motor 61, the slide base 40, the cam groove 31 and the link mechanism 80 serve as driving means, the lid 1a of the dashboard 1 serves as a cover member, and the spring 15 serves as biasing means. Configure.

The form of the movement and the change of the posture of the display are not limited to those shown in FIGS. 2 to 6, but may be any other form as long as the display is configured to abut the lid member on the vehicle side and push it open. May be. For example, the display may simply rotate about a predetermined axis.
The mounting position of the roller may be any position as long as it can contact the lid member, and is not particularly limited to the corner between the back surface and the top surface.

[0031]

According to the present invention, since the display is provided separately from the lid member on the vehicle side, there is no need to consider the shape and color of the vehicle side when manufacturing the monitor device. In addition, when the display moves from the storage position to the use position, a part of the display comes into contact with the lid member and pushes the lid member open, so that the display driving mechanism and the lid member are connected. In addition to reducing the number of man-hours when the vehicle is mounted, the operation of the occupant when using the display is reduced as compared with the case where the display is protruded after the lid is manually opened. If a roller is provided at a contact position with the lid member of the display, and the roller is configured to push open the lid member while rolling on the lid member, the lid member can be smoothly opened with the movement of the display. , The occurrence of sliding noise can be prevented. If at least a portion of the roller that is in contact with the lid member is formed of rubber, even when the lid member hits the display due to vibration or the like, generation of unpleasant noise can be suppressed to a minimum. If the roller is urged toward one of the shaft supports by the urging means, rattling of the roller can be eliminated and low-pitched noise can be prevented. When the display reaches the use position when the display is tilted in the opposite direction via the upright posture, if the display changes its posture without moving the lid member from the upright posture to the use position posture, it is opened once Undesired movements such as the lid member being driven in the closing direction can be prevented, and a sense of quality can be obtained.
