Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for a vehicle electric mirror capable of adjusting a mirror angle by remote control.

(Prior Art) In a conventional remote control device for a vehicle electric mirror,
A supporting portion for swingably supporting the mirror portion, and a pair of operating rods that are disposed at a substantially right-angled positional relationship with respect to the supporting portion and protruded and retracted are defined by the supporting portion and the pair of operating rods. It is known that the mirror is driven by a motor and a gear mechanism disposed in a space to adjust the angle of the mirror in the vertical and horizontal directions (for example, see Japanese Patent Application Laid-Open No. 60-155492).

(Problem to be Solved by the Invention) In a conventional remote control device for a vehicle electric mirror,
Operating rods that are driven vertically and horizontally with respect to the pivot center of the mirror holder that supports the mirror are disposed in a substantially right angle positional relationship. Further, the mirror is inclined in the left-right direction so as not to be perpendicular to the traveling direction of the vehicle body but to face the side of the vehicle body in order to obtain a rear view for the driver. Therefore, it is good to adjust the mirror in the left-right direction. However, in the case of adjusting the mirror in the up-down direction, the mirror image also moves in the left-right direction. There was a problem that the property was poor.

The present invention has been made in view of the above-described problems of the related art, and an object of the present invention is to adjust the angle of the mirror in the up-down direction, and it is necessary to adjust the angle in the left-right direction again. It is an object of the present invention to provide a remote control device for a vehicle electric mirror which does not have good operability.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a first aspect of the present invention is a support section for swingably supporting a mirror mounting holder, a vertical drive section for tilting the mirror upward or downward, and a mirror. Remote control device for an electric mirror for a vehicle, provided with a drive unit including a left and right drive unit for tilting the drive unit to the left or right, and driving the up / down drive unit and the left / right drive unit via drive control means by a switch operation. In the above, the drive control means controls the drive of the vertical drive unit in accordance with the mirror upward operation or the downward operation of the switch, and the image projected on the mirror moves right and left with the upward or downward inclination of the mirror. It is a control means for correcting and controlling the leftward and rightward angles by the right and left drive units as much as possible.

A second aspect of the present invention is characterized in that the drive control means is a control means for turning on the left and right drive units for a predetermined time after the up and down drive unit is turned off.

A third aspect of the present invention is characterized in that the drive control means is a control means for alternately and repeatedly controlling the up-down drive unit and the left-right drive unit a plurality of times.

According to a fourth aspect of the present invention, the drive control means is a control means for intermittently turning on the left and right drive units when the vertical drive unit is in the ON state.

The driving control unit may be configured to control the left and right driving units at a lower speed than the up and down driving unit when the up and down driving unit is in the ON state.
It is characterized by a control means for ON control.

(Operation) According to the first aspect, when the mirror is adjusted upward or downward, the image projected on the mirror does not move to the left or right with the upward or downward tilt of the mirror. Tilt can be automatically corrected.
Therefore, it is not necessary to perform a leftward angle correction operation or a rightward angle correction operation each time the mirror is adjusted upward or downward.

According to the second aspect, the left and right drive units are controlled to be ON for a predetermined time after the up and down drive units are turned off. Therefore, the vertical direction adjustment of the mirror and the correction of the left and right tilts associated therewith are separately performed. be able to.

According to the third aspect, since the up-down drive unit and the left-right drive unit are alternately and repeatedly controlled a plurality of times, the up-down drive unit and the left-right drive unit are not simultaneously turned on, and the mirror is turned up and down. The adjustment and the correction of the left and right inclination accompanying the adjustment can be performed separately.

According to the fourth aspect, since the left and right driving units are intermittently turned ON when the vertical driving unit is in the ON state, the image is projected on the mirror even though the vertical driving unit is in the ON state. The left and right tilts of the mirror can be automatically corrected by the amount by which the image moved left and right.

According to the fifth aspect, when the up / down driving unit is in the ON state, the left / right driving unit is ON-controlled at a lower speed than the up / down driving unit, so that the up / down driving unit and the left / right driving unit are simultaneously turned on. Despite this, the left and right tilts of the mirror can be automatically corrected by the amount that the image projected on the mirror has moved left and right.

As a result, the angle of the mirror in the vertical direction can be adjusted without moving the image of the mirror in the horizontal direction.

Similarly, when the push button is pressed, the mirror is turned to the right so that the image of the mirror does not move in the left and right direction by the amount of the upward movement of the mirror.

That is, as shown in FIGS. 1 to 4, the drive control means 3 controls the drive of the up / down drive unit 18 in accordance with the mirror downward operation of the push button switch group (switch) 4;
The angle correction control is performed by the left and right drive unit 17 to the left by an amount corresponding to the rightward movement of the image projected on the mirror with the downward inclination of the mirror. The drive control means 3 controls the drive of the up / down drive unit 18 in response to the mirror upward operation of the push button switches (switches) 4, and the image projected on the mirror follows the upward tilt of the mirror. The angle correction control is performed by the left and right drive unit 17 rightward by the amount of movement to the left.

Therefore, when the mirror is adjusted upward or downward, the leftward and rightward inclinations are automatically corrected so that the image projected on the mirror does not move left and right with the upward or downward inclination of the mirror. Can be. Therefore, it is not necessary to perform a leftward angle correction operation or a rightward angle correction operation each time the mirror is adjusted upward or downward.

Further, after the vertical drive unit 18 for tilting the mirror upward or downward is turned off, the left / right drive unit 17 for tilting the mirror left or right is ON-controlled for a predetermined time, so that the mirror vertical adjustment and And the correction of the left and right inclinations can be separately performed.

The mirror is turned on so that the mirror is turned to the left, and turned off after a predetermined time. And the above ON-O
By repeating FF multiple times, the angle of the mirror can be adjusted in the vertical direction without moving the image in the horizontal direction.

Similarly, when the push button is pressed, the mirror is turned to the right so that the image of the mirror does not move in the left and right directions by the amount of the upward movement of the mirror.
