It consists of The display is provided with a pair of lock pins that can protrude laterally, and the slide rail is provided with a plurality of holes in which the lock pins can be engaged, and a knob provided on the display is manually operated. , The slide rail and the display are protruded from the housing, the display is rotated to a desired angle, the lock pin is fitted into the hole, and the display is held at that angle. It is configured as follows.

[0003] However, such a conventional in-vehicle display device has a drawback that operability is poor because the display must be manually operated to set the display in a use state or return to a storage state. . In order to solve this conventional problem, the present applicant has developed an in-vehicle display device capable of automatically performing operations from drawing out the display to stand-up and storage by a simple operation. We filed a patent application with -170354.

The present invention has been made to provide a vehicle-mounted display device which is capable of performing a series of operations from drawing out of the display to stand-up and storage, eliminating the drawbacks of the conventional vehicle-mounted display device, and having excellent operability. An object of the present invention is to further improve the invention of the prior application, and to provide an in-vehicle display device configured to be able to reliably hold a desired set angle when the display is started up in a use state.

The angle is set according to the number of rotations of the motor (it does not matter if the position varies depending on the product)
It is held by the electromagnetic brake of the motor driver. However, since the display of the in-vehicle display device has a considerable weight, the holding force is weak only by holding by the electromagnetic brake, and in the worst case, the display may fall down due to vibration or the like. An object of the present invention is to provide an in-vehicle display device having a lock mechanism for avoiding such disadvantages and securely holding the display at a set angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view showing a state where a display of an in- vehicle display device according to an embodiment of the present invention is housed . In the drive mechanism of this device,
The same components are denoted by the same reference numerals, and redundant description will be omitted.

In the figure, reference numeral 40 denotes a switch for supporting the display 3.
A solenoid lock mechanism provided on the ride body 2,
This solenoid lock mechanism 40 is driven by the second motor 7.
The final drive gear 37 of the second gear train 8 to be driven
A plurality of holes 41 arranged in the circumferential direction and
And a fixed rod 43
The operation is performed by a solenoid 42. Also, the drive gear
As shown in FIG. 2B, a position detecting gear 44 is
Meshes with each other and faces one side of this position detection gear 44
And a photo reflector 45 is installed.

FIG. 3 illustrates the control principle of the solenoid lock mechanism 40. The light is projected from the photo reflector 45 to the position detection gear 44, the reflected light is received, and the rotation angle of the drive gear 37 is adjusted. (Accordingly, the rotation angle of the display 3) is detected, and a detection pulse signal from the photo reflector 45 is input to the control microcomputer to control the control microcomputer.
The display 3 is held at a desired angular position by driving the solenoid 42 according to a control signal from the microcomputer and inserting the locking rod 43 into the hole 41 of the driving gear 37 to lock.

The plurality of holes 41 of the drive gear 37 are provided for each angle of the drive gear 37 which makes a required rising angle (for example, 80 °, 90 °, 100 °, 110 °) with respect to the horizontal position of the display 3. The fixing rod 43 of the solenoid 42 is inserted into one of these holes 41 and the angle of the display 3 is maintained, but the angle is set (changed).
In this case, it goes without saying that the fixing rod 43 must be accurately inserted into the predetermined hole 41. The operation for this is performed as follows. FIG. 4A is an operation chart thereof. That is, when the angle is changed, the solenoid 42 is pulled (the retreating direction of the rod 43), and then the motor 7 is rotated. When the input rotation pulse reaches a specified rotation (the number of rotations not affected by the variation due to the product), the solenoid 42 is made free (the forward direction of the rod 43). After the free operation, the motor 7 is continued to be driven for about one second (depending on the timing when the solenoid 42 is released and the timing when the rod 43 can be reliably inserted by driving the motor 7).

By the way, once the display 3 is stored,
The initial angle at the time of re-starting after setting is to be the angle set before storage , so
The angle before storage is stored. Specifically, the position
After the detection gear 44 detects a reference angle, for example, 80 °
This is performed by storing the number of pulses. And the criteria
Since the number of pulses after detecting the angle is stored,
Before the rod 43 is inserted into the hole 41 for degree setting,
The extra number of pulses may be counted due to slippage, etc.
There is no accumulated error caused by
Can be set .

FIG. 4B shows an operation chart when the display 3 rises from the horizontal position (0 °) to the reference angle 80 °.
With the start, a pulse is simultaneously generated with the start of the rising operation of the motor 7. Angle detection sensor means 80 ° ON
(H → L) The motor 7 is driven for about one second more than that, so that the rod 43 of the solenoid 42 can be securely fitted into the hole 41 and locked.

When the rising angle of the display 3 is set to 80/90/100/110 as described above, the down button 14 and the up button 15 are operated so that the motor 7 is turned 10 degrees during this time. Be able to rotate with feeling. FIG. 4 (c) is an operation chart with a sense of 10 °, which detects the rising or falling of the pulse, and makes the solenoid 42 free at the third time. Solenoid 4
2 is set to free, and the motor 7 is driven for one second thereafter. If the rod 43 of the solenoid 42 locks into the hole 41 within one second, the rotation of the motor 7 will slip for the remaining time.

In the above-described display rising angle determination operation, no trouble occurs when the operation is performed normally, but the angle position is changed to a predetermined value (80) by a tampering operation (forcibly lowering the display during the angle determination operation).
(゜, 90 °, 100 °, 110 °), there is a possibility that the angle position will be 80 ° or less. In this case, since the lock by the rod 43 due to the driving of the solenoid 42 is not performed, the display 3 may fall down due to vibration or the like. In order to avoid such a problem, in the present invention, the operation at 80 ° or more is always monitored by the angular position detecting means (the position detecting gear 44 and the photo-reflector 45 in the above embodiment) for detecting the reference angular position 80 °. When the angle position is less than 80 °, the motor 7 is rotated forward (rotated in the rising direction of the display 3), and the rod 43 of the solenoid 42 rises under the control of a controller (control microcomputer). Angle 8
The lock is performed by fitting into the hole 41 of the drive gear 37 corresponding to 0 °.

In the above-described embodiment, the rotation of the position detecting gear 44 is detected by the photo reflector 45 as the position detecting means. However, the rotation of the drive gear 37 itself may be detected by a photo reflector or the like. Further, as the detecting means of 80 °, a position such as the driving gear 37 and the arcuate gear 38 whose position changes according to the rotation angle of the display 3 can be detected by a mechanical switch or another sensor.

[0024]

As described above , according to the present invention, the display
When pulling out the ray and turning it to set it in use,
In response to the position detecting means detecting a predetermined rotation position,
Activate the holding means in the direction to hold the display, and
The motor is driven further in the same direction for a predetermined time after the operation of
Therefore, even if the operation timing of the holding means is too early,
