Description

[Detailed description of the invention] The present invention is a display device for a car. Specifically, the display device swings (left and right rotation) and tilts (up and down rotation).
The present invention relates to a direction changing device that performs a motion.

Recently, a translucent map membrane has been installed on the display surface of a CRT (Cathode Ray Tube) to generate bright spots on the display surface of the cathode ray tube, and the bright spots are shown on the map membrane to show the driver's current location. A CRT display device has been developed to display the vehicle's driving position. This device calculates the driving route of the car using a microcomputer using the car's driving signals obtained from rotation detectors installed on the car's wheels and direction detectors such as a year-round compass, and based on the calculation output. CRT
This creates a bright spot above the vehicle that moves along the path of the vehicle. This kind of CRT display device is
It is usually fixed to the dash board near the driver's seat, and the display surface is oriented toward the driver for easy viewing.

On the other hand, this CRT display device is sometimes used in rallies and the like, and in this case, it is better for a navigator sitting in the passenger seat to operate the device. In such a case, loosen the fixing screws on the device, turn the display toward the passenger seat, tighten the screws, then loosen the screws again after the rally is over, turn the device toward the driver, and then turn the screws back on. must be tightened.

In this way, since conventional CRT display devices are fixed to the vehicle's dashboard board, the orientation of the display surface cannot be changed.If the orientation of the display surface must be changed, it is necessary to change the orientation of the display surface as described above. tedious work becomes necessary.
Also, if the operator is higher or lower than the standard sitting height, the CRT display set for the standard person will be very difficult to see.

This invention is a new invention that improves the above-mentioned drawbacks of the conventional technology.The purpose of this invention is to easily move the display surface of a display device mounted on a vehicle in a desired direction vertically or horizontally using a rotary lever or the like. The goal is to provide a device that can.

This rotating shaft 18d is slightly movable in the longitudinal direction, and is positioned in either a pushed-in position (in the direction of arrow A) or a pulled-out position (in the direction of arrow B) by a detent mechanism 18e provided on the pivot wall 18c. be done. Further, a gear bearing 19 having teeth on its inner surface is fixed to the pivot wall 118b, and lock teeth 18f are formed near the gear bearing 19 on the rotating shaft 18d. When the rotating shaft 18d is pushed in, the locking teeth 18f mesh with the teeth of the gear cutting bearing 19 to lock the rotating shaft 18d from rotating.
When the rotating shaft 18d is pulled out, these meshes are released and the rotating shaft 18d can freely rotate. These gear bearings and lock teeth form a lock member. A rotating shaft 18g is rotatably inserted into the tip of the rotating shaft 18d coaxially therewith. An eccentric cam disc 20 is attached to this rotating shaft 18g, and the eccentric cam disc 20 has a cam groove 20a as clearly shown in FIG.
A piece 22 attached to the tip of the wire 21 is movably fitted into the cam groove 20a. 23 is a wire guide. Although not shown in FIG. 3, a return mechanism such as a torsion coil spring for returning the rotating shaft 18g is provided between the pivot wall 18a and the rotating shaft 18g. A rotational force is applied to the eccentric cam disc 20 in the counterclockwise direction in FIGS. 3 and 4,

The lock plate 24 is attached to the shaft body 7 so that it can be rotated by a predetermined amount in the tilt (up and down) direction, and cannot be rotated in the left and right directions. Reference numerals 26 and 27 are clip plates, which are connected and supported together by a shaft 28;
This shaft rod 28 is supported by the cut and raised piece 10d of the holding plate 10. Inside the clip plates 26 and 27 are lock pads 29 and 3 made of felt material.
0 is pasted. 31 and 32 are springs, and the pads 29, 3 of the clip plates 26, 27
The clip plates 26 and 27 are inserted between the opposite ends of the clip plates 26 and 27 to constantly press the lock pads 29 and 30 against the lock plate 24. 3

With a force of 32, its short axis faces toward the clip plates 26 and 27. One end of a lever 34 is attached to the end of the operating cam 33, and the wire 21 is attached to the other end of this lever 34. These clip plates, operating cams, springs, etc. form a locking member. Reference numeral 35 denotes a wire guide attachment portion, which is attached to the holding plate 10. In addition, FIG. 5 is a partial rear view of the rotating shaft portion as seen from the rear after assembly.

Next, a tilting operation for moving the main body 1 in the vertical direction will be described.

Pull out the rotary knob 4 toward you and remove the gear bearing 19.
Disengage the lock teeth 18f and rotate the rotating shaft 18d.
After making it rotatable, the rotation knob 4 is rotated.
This rotational force is transmitted to the threaded rod 11 via the gear group 18h, causing it to rotate. As threaded rod 11 rotates, nuts 12 and 13 move toward or away from each other. Therefore, the hinge member 16 moves up and down, and the holding plate 10 connected to the hinge member 16 is rotated in the up and down direction about the bearing sleeve 10a, so that the display surface 1a of the main body 1 is directed in a desired direction. At this time, the lock plate 24 connected to the holding plate 10 by the clip plates 26 and 27 also moves up and down about the pin 25. When the rotary knob 4 is pushed in after the display surface 1a has moved by a predetermined amount, the lock teeth 18
f meshes with the gear bearing 19, the rotating shaft 18d and the threaded rod 11 stop rotating, and the main body 1 is locked. Therefore, even if vibrations are applied to the display device, the elevation angle of the main body 1 does not change at all, and even if the rotation knob 4 is carelessly rotated, the main body 1 does not move.

Next, the operation of rotating the main body 1 in the left-right direction will be explained.

When the rotary knob 5 is rotated in the direction of arrow A in FIG. 2, the eccentric cam disc 20 is rotated in the direction of the arrow in FIG. 4, and the piece 22 moves in the cam groove 20a to pull the wire 21. This wire 21
When the lever 34 is pulled, the operating cam 33 is rotated, and the long axis of the operating cam 33 approaches the direction of the clip plates, and these two clip plates 2
6 and 27 are pushed open against the force of springs 31 and 32 to release the clamping force of the lock plate 24. When the main body 1 is pressed in either the left or right direction in this state, the retaining plate 10, rotating plate 8, and rotating bearing plate 9 rotate smoothly around the shaft 7, and the two clip plates 26 27 slides on the lock plate 24, and the main body 1 swings left and right. When the rotation knob 5 is released after the main body 1 has been rotated by a predetermined angle, the knob 5 is returned to the previous position by the return torsion coil spring of the rotation shaft 18g (knob 5) and the tension of the wire 21 is removed. power is released,
The clip plate 2 is rotated by the force of the rotation knob 4 springs 31 and 32.
6 and 27 strongly clamp the lock plate 24 and lock the rotating plate 8 and the holding plate 10 so that they cannot rotate.
Therefore, the main body 1 is swingably held at a desired position.
In this state, as mentioned above, the clip plate 2
6 and 27 strongly clamp the lock plate 24, so that it will not move even if vibration is applied to the main body 1.

In addition, in the embodiment described above, the retaining plate 10
The horizontal rotation position of the holding plate, that is, the main body 1, is locked by clip plates 26 and 27 attached to the holding plate 10. 8 and a suitable fixing member, for example, a locking mechanism using a known detent mechanism may be provided between the rotary plate 8 and the mounting plate 6. In this case, the locking mechanism may be provided between the rotating plate 8 and the mounting plate 6. It can be rotated and positioned from side to side.

As explained in detail above, according to the present invention,
Since the display surface of a display device mounted near the driver's seat of a vehicle can be rotated in the left-right direction, the display surface can now be observed not only by the driver but also by a person sitting in the passenger seat. In addition, since the display device can be rotated vertically, it has become possible for all users to easily view the display surface, regardless of the sitting height of the user. In addition, the elevating mechanism for vertical movement of the main body is installed on a rotary plate that rotates left and right together with the main body.
A first control means for controlling the rotation of the threaded rod of the elevating mechanism and a second control means for controlling the clamping force of the locking member to inhibit left and right rotation of the holding plate can be operated independently. Therefore, not only can the main body be rotated up and down at any rotational position in the horizontal direction of the main body, but the mechanism is also compact.

In the above-mentioned embodiment, a vehicle running position display device was used as an example, but the display device of the present invention is not limited to this, and can be used as a CRT for rear confirmation.
Of course, the present invention can also be applied to various display devices using displays, liquid crystals, EL elements, etc.
