When the pair of supports 54 and 56, which are projected by the driving unit 70, are projected at different speeds, the top shape of the sunshade 10 can be curved or inclined.

A pair of supports 54 and 56 are connected to the upper ends of both end portions of the sunshade 10, and among the supports 54 and 56 simultaneously protruding when protruding toward the window 4, the support 56 protrudes at a high speed. ) Reaches the end of the high side of the window 4, the support 54 protruding at a slow speed reaches the low side end of the window 4.

Thus, even if the upper end of the window 4 is made of curved or inclined surface, it is possible to cover the entire window 4 by installing the sunshade 10 having the same or similar shape as the shape of the window 4.

At this time, since the power of the driving unit 70 is transmitted to the auxiliary shading film 12 by the power transmission unit 80, the auxiliary shading film 12 along with the shading film 10 also appears on the side of the auxiliary window (6). Therefore, it is possible to cover the small auxiliary window 6 which is disposed on one side of the window 4 by using the auxiliary sunscreen 12.

Support 50 is provided on the top of the sunshade 10, the upper support 52 is in close contact with the top of the window 4, the first support 54 connected to one side of the upper support 52, and the upper end And a second support 56 connected to the other side of the support 52, and a third support 58 connected to the auxiliary sunscreen 12.

Since the upper support 52 is formed in the same shape as the upper shape of the window 4 and the upper shape of the sunscreen 10, the sunscreen 10 may be completely protruded by the first support 54 and the second support 56. At this time, the upper support 52 is in close contact with the top of the window 4 to cover the entire window (4).

The first support 54, the second support 56, and the third support 58 are formed in a panel shape which is installed to be protruded from the inside of the vehicle door 2 to the window 4, and has a narrow width. It can be made to be easily sunk to the window 4 side from the inside of the door (2).

Here, the third support 58 is a gear tooth is formed on one side so that the rise or fall by the power transmission unit 80 is connected to the end of the driven shaft 86 to be described later in a rack and pinion manner.

Accordingly, the third support 58 is raised or lowered by the rotational movement of the driven shaft 86 transmitted from the driving unit 70 to raise or lower the auxiliary sunscreen 12.

The driving unit 70 includes a first wire 76 to which the first support 54 is connected, a second wire 78 to which the second support 56 is connected, and a first to which the first wire 76 is wound. And a double drum 74 having a winding portion 74a and a second winding portion 74b on which the second wire 78 is wound, and a motor 72 for driving the double drum 74.

The first wire 76 is provided with a first flow piece 76b and connected to the first support 54, and the second wire 78 is provided with a second flow piece 78b and a second support 56. Since the double drum 74 is rotated by the driving of the motor 72, the first flow piece (76b) and the second flow piece (78b) installed on the first wire 76 and the second wire (78). The elevating and lifting up the first support 54 and the second support 56.

Here, the first winding portion 74a and the second winding portion 74b have different diameters, and the diameter of the first winding portion 74a is smaller than that of the second winding portion 74b, so the double drum ( It can be seen that the amount of movement of the first wire 76 is small compared to the amount of movement of the second wire 78 when 74 is rotated one turn.

Therefore, the distance and the speed at which the first flow piece 76b and the first support 54, which are installed on the first wire 76, rises, are determined by the second flow piece 78b and the second support which are installed on the second wire 78 ( 56 becomes small compared with the rising distance and speed.

Since the height at which the first support 54 and the second support 56 are lifted in the same time is different, even if both ends of the upper end of the sunshade 10 start to rise equally from the take-up roll 30, The end on the 54) side is raised slowly compared to the end on the second support 56 side.

Therefore, the first support 54 and the second support 56 both reach the upper end of the window 4 at the moment when the ascent of the sunscreen 10 is completed and the driving of the motor 72 is stopped, the upper support 52 is It adheres to the top of the window 4 and covers the entire window 4.

Since the first wire 76 and the second wire 78 are formed in a closed curve wound between the first pulley 76a and the second pulley 78a and the double drum 74, a single motor 72 is provided. As a result, when the pair of supports 54 and 56 are simultaneously raised and lowered, power transmission can be easily performed.

The straight wire is easy to transmit power when the support is wound around the drum to lower the support, but when the wire is released from the drum and the support is raised, a guide must be provided to the top of the window to maintain a constant direction of the wire. It can be seen that the structure of the drive unit 70 of the vehicle sunshade according to an embodiment of the invention is a simple structure compared to the drive unit having a straight wire.

The drive unit 70 of the vehicle sunshade according to an embodiment of the present invention is also provided with a guide 77 for supporting the first wire 76 and the second wire 78, the first flow piece (76b) and the first Two flow pieces 78b are slidably installed in the guide 77.

As a result, when the first wire 76 and the second wire 78 are moved by the motor 72 and the double drum 74, the first flow piece connected to the first wire 76 and the second wire 78 ( 76b) and the second flow piece 78b slide along the guide 77 in the vertical direction to shed the first support 54 and the second support 56 toward the window 4.

Since the guide 77 is provided inside the door 2 to allow the first flow piece 76b and the second flow piece 78b to flow in the vertical direction, the guide 77 has a simple structure compared to the driving part provided with the straight wire. It can be seen that.

In addition, since the first wire 76 and the second wire 78 are provided with a pipe-shaped covering member 79, the first wire 76 and the second wire 78 are separated from the path during the movement of the power transmission. This can prevent malfunctions that do not occur.

The power transmission unit 80 is provided with a main gear 82 provided on the rotating shaft of the first pulley 76a, and a driven gear 84 connected to the main gear 82 in a bevel gear manner, and having a third support 58. ) Includes a driven shaft 86 connected in a rack and pinion manner.

Therefore, when the first pulley 76a is rotated by the first wire 76, the main gear 82 connected to the rotation shaft of the first pulley 76a is rotated, and the main gear 82 is geared in a bevel gear manner. As the driven gear 84 is rotated, the power transmission direction is changed, and the driven shaft 86 is rotated.

Since the driven shaft 86 rotated in this way is connected to the third support 58 in a rack and pinion manner, the rotational movement of the driven shaft 86 is converted into a linear motion of the third support 58 to form the auxiliary sunscreen 12. Will be raised or lowered.

Here, the third support 58 is installed so as to be retracted to the inside and the outside of the guide member 59 installed in the door 2, so that when the rotational force of the driven shaft 86 is transmitted, it is raised or lowered in the vertical direction. The sunscreen 12 is raised or lowered to the side of the auxiliary window (6).

Of course, the power transmission unit 80 may be applied to various embodiments that can raise or lower the auxiliary sunscreen 12, but those skilled in the art who are familiar with the technical configuration of the present invention can be easily changed and implemented. The drawings and descriptions will be omitted.

Looking at the operation of the vehicle shade device according to an embodiment of the present invention configured as described above are as follows.

First, when the occupant operates the control switch 70a to block sunlight while driving the vehicle, power is applied to the motor 72 so that the double drum 74 rotates counterclockwise on the drawing. And the second wire 78 raises the first flow piece 76b and the second flow piece 78b.

The first support piece 54 and the second support piece 56 are lifted to the window side by the first flow piece 76b and the second flow piece 78b that are raised along the guide 77, and the sunscreen 10 and The upper support 52 is raised to cover the window (4).

At this time, the first wire 76 wound on the first winding portion 74a having a smaller diameter than the second winding portion 74b has a distance that is moved when the double drum 74 is rotated once. Since it is small compared to 78, the first support 54 is raised at a slower speed compared to the second support 56.

When the driving of the motor 72 is continued and the protrusion of the sunscreen 10 is completed, the upper end of the first support 54 reaches the upper end of the lower window 4, and the upper end of the second support 56 is The top of the high window 4 is reached so that the upper support 52 is in close contact with the top of the window 4.

At this time, the rotational force of the first pulley 76a is transmitted to the third support 58 by the power transmission unit 80 consisting of the main gear 82, the driven gear 84, and the driven shaft 86. The lifting or lowering speed of the third support 58 is determined by the rack axion structure provided between the coaxial 86 and the third support 58.

In addition, since the auxiliary window 6 is generally formed smaller than the window 4, the ascending or descending speed of the third support 58 is compared with the first support 54 and the second support 56. It is desirable to design the shape of the rack and pinion to be the smallest.

As a result, a curved surface or an inclined surface is provided at the top, and the window 4 provided with the auxiliary window 6 can be completely covered.

When inserting the sunshade membrane 10 to the door 2 side, the occupant begins to descend the sunshade membrane 10 when the operator operates the control switch 70a reversely, when the power is applied to the motor 72, the double drum 74 is Rotating clockwise in the drawing, the first and second wires 76 and 78 lower the first flow piece 76b and the second flow piece 78b by the rotation of the double drum 74. .

At this time, the first wire 76 wound on the first winding portion 74a having a smaller diameter than the second winding portion 74b has a distance that is moved when the double drum 74 is rotated once. Since it is small compared to 78, the first support 54 is lowered at a slower speed compared to the second support 56.

In the state where the driving of the motor 72 is continued and the insertion of the sunshade film 10 is completed, the upper end of the first support 54 and the upper end of the second support 56 simultaneously reach the take-up roll 30. Both ends of the 52 are in close contact with the take-up roll 30.

At this time, the rotational force of the first pulley 76a is transmitted to the third support 58 by the driven shaft 86. When the first pulley 76a is rotated clockwise, the rotational movement of the driven shaft 86 is also reversed. Since the third support 58 connected in a rack and pinion manner to the driven shaft 86 is lowered to lower the auxiliary sunscreen 12.

As a result, it is possible to cover the window 4 made of various shapes and provided with the auxiliary window 6, it is possible to provide a vehicle awning device that reduces the number of parts.

8 is a perspective view showing a connection structure of a double drum of a vehicle shade device according to another embodiment of the present invention.

Referring to FIG. 8, in the vehicle sunshade according to another embodiment of the present invention, a coating member 179 is applied to the skin of the first wire 176 and the second wire 178, and the coating member 179 is applied. Since the first wire 176 and the second wire 178 is in close contact with the first winding portion 174a and the second winding portion 147b, the dual drum 174 and the covering member 179 without a separate power transmission member. The first wire 176 and the second wire 178 is moved by friction between the) to perform power transmission.

Therefore, compared to an embodiment in which gear teeth are formed on the double drum 74 (see FIG. 4), the first wire (76: FIG. 4), and the second wire (78: FIG. 4), the power transmission is simpler. It can be seen that.

Of course, the power transmission structure between the dual drum and the first wire and the second wire can be applied in various ways, but those skilled in the art who are aware of the technical configuration of the present invention can easily implement various embodiments by simple design changes.
