## Abstract

An apparatus for driving a headlight cover includes a rotary shaft rotated by a motor and covered with shields. A rotary member extends from the rotary shaft, rotates with the rotary shaft, and has at least one protrusion on a surface. A plurality of guides are fitted around the rotary member and have grooves on inner sides, respectively, to receive the protrusion of the rotary member. An elastic member is fitted on the guides.

## Claims

### Claim 1

An apparatus for driving a headlight cover, comprising:
a rotary shaft rotating by a motor and covered with shields;
a rotary member extending from the rotary shaft, the rotary member rotating with the rotary shaft and having at least one protrusion on a surface thereof;
a plurality of guides fitted around the rotary member and having grooves on inner sides thereof, respectively, to receive the protrusion of the rotary member; and
an elastic member fitted on the guides.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the motor is a direct-current (DC) motor.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein each of the guides further has a support which extends the elastic member when the guides rotate with the rotary shaft.

### Claim 4 (depends on 3)

The apparatus of claim 3, wherein a support of a first guide of the plurality of guides is coupled to a first end of the elastic member to extend the elastic member in a first direction, and a support of a second guide is coupled to a second end of the elastic member to extend the elastic member in a second direction.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the grooves allow the protrusion to turn at predetermined angles.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein a groove of a first guide of the plurality of guides allows the protrusion to turn in a second direction, and a groove of a second guide allows the protrusion to turn in a first direction.

### Claim 7 (depends on 1)

The apparatus of claim 1, further comprising a stopper preventing the guides from rotating in predetermined directions.

### Claim 8 (depends on 7)

The apparatus of claim 7, wherein the stopper prevents a first guide of the plurality of guides from rotating in a second direction and a second guide from rotating in a first direction.

### Claim 9 (depends on 1)

The apparatus of claim 1, further comprising:
a first stopper preventing a second guide of the plurality of guides from rotating in a direction opposite to a rotational direction of the rotary shaft when the second guide returns after rotating with the rotary shaft and preventing the second guide from rotating in the rotational direction of the rotary shaft when a second guide rotates with the rotary shaft; and
a second stopper preventing the second guide of the plurality of guides from rotating in the direction opposite to the rotational direction of the rotary shaft when the second guide returns after rotating with the rotary shaft and preventing the second guide from rotating in the rotational direction of the rotary shaft when the second guide rotates with the rotary shaft.

### Claim 10 (depends on 1)

The apparatus of claim 1, further comprising a controller controlling the motor in accordance with a speed of a vehicle.

### Claim 11 (depends on 10)

The apparatus of claim 10, wherein when the vehicle breaks down, the controller stops the control.

### Claim 12 (depends on 1)

The apparatus of claim 1, wherein the guides are arranged in parallel on the rotary member and rotate selectively in accordance with rotational directions of the rotary shaft rotating by the motor.

### Claim 13 (depends on 7)

The apparatus of claim 7, wherein the stopper is disposed at a side of supports of the guides.
