Description

Field of view enlargement device when vehicle reverses

The present invention relates to an apparatus for expanding a field of view when reversing a vehicle. More specifically, when the vehicle is retracted, the rearview mirror is automatically enlarged and the rear lights are adjusted to remove the blind spots while the rear view is maximized. The present invention relates to a device for expanding the field of view at the time of reversing the vehicle so that it can be secured.

In general, when driving a vehicle, traffic conditions on the left, right, or right rear side are observed through side mirrors or room mirrors mounted inside and outside the vehicle.

In general, when the vehicle is reversed, the driver's body is twisted backwards regardless of the experienced person or the beginner, and the rear window glass is mainly focused on the rear window glass to assist the rear mirror.

However, if the driver's body is twisted backward when the vehicle is parked backwards, it is not only unstable and extremely inconvenient, but also difficult to cope with the sudden situation. In addition, if you back up with only the rear view mirror or side mirror, you are more likely to have blind spots with unrecognized rear obstacles. The risk is considerably higher.

Of course, in some cases, a larger sized room mirror may be added instead of a room sized mirror mounted at the time of shipment of the vehicle to minimize blind spots, but this may not be easy to spread sunvisor. In addition, in the event of an accidental collision, there is a higher risk of fatally damaging the safety of the driver or passenger.

Therefore, the present invention was devised to solve the above-mentioned problems, and an object of the present invention is to automatically enlarge the size of the room mirror at the time of reversing the vehicle and to selectively increase the brightness of the reversing light through the room mirror only. The present invention provides a device for expanding a field of view when reversing a vehicle, which may reduce the risk of an accident by minimizing blind spots even when viewed from the rear.

In order to achieve the above object, a device for expanding a field of view when reversing a vehicle includes a first and a second auxiliary mirror installed on a bottom surface and a side of a room mirror main body so as to be slidable, and the first and second auxiliary mirrors. First and second motors coupled to each other so as to be inserted and withdrawn, and driven in the forward and reverse directions, a reverse detection switch for detecting a reverse shift state of the vehicle, and first and second motors according to a detection signal of the reverse detection switch. It is characterized in that it comprises a control unit for controlling an electric signal to be turned on and off at the same time as the first, second motor drive unit to forward and reverse rotation.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a block diagram schematically illustrating a configuration of a device for expanding a field of view at the time of reversing a vehicle according to the present invention.

In the figure, reference numeral 10 denotes a room mirror of the present invention, which is provided with a main mirror 12 attached to the front surface of the main body 11, and particularly the first, 2 auxiliary mirrors 14 and 16 are built-in.

The first and second auxiliary mirrors 14 and 16 are slidably installed on guide rails (not shown), and the first and second motors 20 are respectively provided at one end of the auxiliary mirrors 14 and 16. 30 is connected to enable insertion and withdrawal of the auxiliary mirrors 14 and 16 into the room mirror body 11, for example in a rack and pinion manner.

Reference numeral 40 denotes a reverse detection switch, which is installed on the reverse shift gear side (not shown) to detect a reverse shift state of the vehicle.

Reference numeral 50 denotes a control unit which inputs an electrical signal of the reverse sensing switch 40 to drive the first and second motors 20 and 30 forward and reverse by the first and second motor drivers 22 and 32. It is to control the output so that the electrical signal, and the main reversing light 60 can be turned on.

Furthermore, for example, if the auxiliary reversing light switch 70 is additionally installed on the shift lever (not shown) or in another convenient position, and the auxiliary reversing light 80 is additionally installed on the rear side of the vehicle body in which the main reversing light 60 is installed. In addition, since the brightness of the auxiliary reversing lamp 80 is adjusted to the brightness of the normal main reversing lamp 60 when the vehicle is reversed, it is very preferable.

Of course, even in this case, the controller 50 receives the electrical signal from the auxiliary reverse light switch 70 and outputs a signal to enable the auxiliary reverse light 80.

The operation process of the apparatus for expanding a field of view when the vehicle is reversed according to the present invention provided as above will be described in more detail with reference to the flowchart of FIG. 2.

After the reverse gear is shifted in order to reverse the vehicle (step S1), the reverse shift state is input to the controller 50 by the reverse detection switch 40. Subsequently, when it is determined in the step S2 that the gear shift in accordance with the reverse shift has been made, the control unit 50 outputs an electrical signal so that the main reverse light 60 is turned on (S3 step) and at the same time the room mirror main body 11 The first and second auxiliary mirrors 14 and 16 are pulled out from the bottom and side surfaces of the base plate (S4 step).

At this time, the first and second motors 20 and 30 can be rotated in the forward or reverse directions through the first and second motor driving units 22 and 32, respectively. 2 Auxiliary mirrors 14 and 16 are pulled out (in this case, it is assumed to rotate in the forward direction for convenience).

On the other hand, if it is determined in the step S2 that the reverse shift has not been performed, it is determined whether the first and second auxiliary mirrors 14 and 16 are in their original positions, that is, in a state of being inserted into the main body 11. S7 step)

At this time, if it is determined in the S7 determination step that it is not in the home position, the controller 50 senses the rotation angles of the first and second motors 20 and 30 and drives the rotation direction in the reverse direction. The auxiliary mirrors 14 and 16 are returned to their original positions so that the auxiliary mirrors 14 and 16 are inserted into the main body 11 which is in the state before the vehicle reverse shift. (S8 step)

Furthermore, if it is judged that the switch 70 is "on" in the S5 determination step when the auxiliary reverse light switch 70 is further installed, the auxiliary reverse light 80 is turned on together with the main reverse light 60 so as to be rearward. Makes the field of vision even brighter.

According to the present invention described above, the size of the rearview mirror is automatically enlarged when the vehicle is retracted to extend the range of the rear view to minimize blind spots of the field of vision and to further increase the brightness of the rear lights. Not only can it be greatly reduced, but also the usability can be increased.
