Abstract

When an obstacle appears in front of the vehicle or the side mirror may be damaged by interference with other vehicles, the side mirror is automatically detected and an alarm sounds and the side mirror is automatically folded, thereby preventing the side mirror from being damaged. To prevent it. In order to realize this, in the automatic folding and alarming apparatus of the side mirror for automobiles according to the present invention, an ultrasonic sensor 2 is installed as an obstacle detecting means in the housing 3 of the side mirror 1, and the signal of the ultrasonic sensor is provided. The receiving control unit operates the buzzer. At this time, the controller is configured to operate the motor 8 as a power source so that the side mirrors linked thereto are folded toward the vehicle body.

Technical Field of the Invention

The present invention relates to an automatic folding and alarm device for a side mirror for a vehicle, and more particularly, when an obstacle appears in front of the side mirror and a possibility of collision occurs, the side mirror is automatically folded toward the vehicle body and an alarm sounds. Relates to automatic folding and alarming of

[Private Technology]

In general, the side mirrors of the vehicle, along with the rearview mirrors installed in the cabin, are provided at both sides of the vehicle so that the situation of the rear and side of the vehicle can be observed while driving.

Therefore, while driving, the driver grasps the situation of the rear roads on the left and right sides of the driving lane, and frequently checks the side mirrors for protection driving when the lane is changed. Such a side mirror is an important device for safe driving of a vehicle.

This side mirror is installed to protrude outward of the door in its function. For this reason, the side mirror often breaks by hitting an obstacle appearing in front or the side mirror of another vehicle.

In order to overcome this disadvantage, it has been proposed to fold the side mirrors toward the rear of the vehicle so that the mirror portion is in close contact with the door. These side mirrors are folded into the door as needed to prevent it from colliding with obstacles or other vehicles or reducing damage. In addition, the force hitting the rear of the vehicle body from the front side to the rear side is flipped back, absorbing the force, and preventing the side mirror from being broken.

[Technical problem to be achieved]

However, the conventional side mirror structure, whether fixed or folding, maintains its unfolded state while the vehicle is running, and thus still suffers from damage caused by collisions with obstacles or other vehicles appearing in the front or rear.

In addition, the conventional folding side mirrors are inconvenient to use because the driver has to go out of the vehicle and fold or unfold as necessary.

The present invention has been made to solve the problems of the prior art, the present invention automatically detects when an obstacle appears in the front of the vehicle or interference with other vehicles, and automatically detects the alarm sound, the side mirror is It is an object of the present invention to provide an automatic folding and alarming device for a vehicle side mirror that is automatically folded.

[Configuration and Function of Invention]

As a means for realizing the above object, the present invention proposes an automatic folding and alarming apparatus for a side mirror for a vehicle having a configuration described below.

That is, the present invention is configured so that the obstacle detection means is installed in the housing of the side mirror, and the control unit receiving the signal of the detection means operates the alarm means. In addition, the control unit is characterized in that the side mirror linked to the motor is folded toward the vehicle body by operating the motor when there is a risk of collision with an obstacle or another vehicle.

According to this configuration, when the side mirror folding and alarming apparatus of the present invention approaches an obstacle or other vehicle appearing in front of the vehicle to the collision possible area, the sensing means detects this and sends a signal to the control unit. In addition to operating the alarm means, the motor is operated so that the side mirror is automatically folded.

EXAMPLE

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment for implementing this invention is demonstrated in detail based on an accompanying drawing.

The accompanying drawings are overall configuration diagrams showing an automatic folding and alarming apparatus for a side mirror for a vehicle according to the present embodiment.

Reference numeral 1 in the drawings refers to the entire side mirror. The side mirror 1 is provided with an ultrasonic sensor 2 as a sensing means for observing an obstacle appearing in front of the vehicle or a collision with another vehicle.

In addition, the housing 3 of the side mirror 1 extends inwardly of the vehicle body 4 and is rotatably coupled by a hinge 5, and is formed in a semicircular shape at its tip, and has a gear formed on the outer circumference thereof. Gear 6 is installed. To the gear of the driven gear 6, a drive gear 7 directly connected to the motor 8 is engaged. As the motor 8, a forward and reverse rotation motor is used.

The ultrasonic sensor 2 and the motor 8 are connected to the controller of this embodiment. This control unit may use an electronic control unit (ECU) when applied to an actual vehicle.

Here, the ultrasonic sensor 2 sends a signal to the controller when an obstacle or another vehicle that appears in front of the vehicle approaches the collisionable area A.

The control unit compares and analyzes the signals of the ultrasonic sensor 2 to determine whether a collision occurs, and when a collision is determined, the motor 8 is operated to show a side mirror 1 interlocked with the motor 8. Fold toward the vehicle body as shown by the dotted line 1 '.

In addition, when it is determined that the collision with the obstacle or other vehicles, the control unit is connected to the alarm means for alerting to inform the driver. The alarm means may be a buzzer or a horn mounted on a vehicle.

According to the above-described configuration of the embodiment, the side mirror folding and alarming device, when there is a collision with the obstacle or other vehicles appearing in front of the vehicle, the ultrasonic sensor 2 detects this and sends a signal to the control unit, The control unit operates the buzzer and operates the motor 8 so that the side mirror 1 is automatically folded toward the vehicle body.

[Effects of the Invention]

Through the embodiments described above, it can be seen that the automatic folding and alarm device of the side mirror for automobiles according to the present invention substantially solves the problems of the prior art.

That is, according to the present invention, when the side mirror is likely to collide with an obstacle appearing in front of the vehicle or another vehicle, the side mirror is automatically sensed and an alarm sounds and the side mirror is automatically folded, thereby preventing damage to the side mirror. It has the effect of preventing in advance.

On the other hand, the present invention is not limited to the above-described specific preferred embodiment, and any person having ordinary skill in the art to which the invention belongs without departing from the gist of the invention claimed in the claims, various modifications Would be possible.
