Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an electric rear curtain device that removes direct sunlight shining through the windshield of an automobile.

[Conventional technology]

In automobiles, direct sunlight may shine through the windshield when the vehicle is parked or in traffic jams.

Particularly in the summer, the temperature inside the vehicle may rise significantly in some areas. Also, the lights of cars following you at night can cause glare. Therefore, various types of sunshades are attached to automobiles.

Among such sunshades, rear curtains are often used as those attached to the rear window side. This rear curtain is installed on the rear package inside the rear window, and is stretched vertically between it and the ceiling interior material to block sunlight and lights that come in through the rear window.

The mainstream of such rear curtains is a roll-up type that is biased in the winding direction. The tip of the rear curtain is then grasped with the hand, pulled up, and secured to the ceiling interior material, allowing it to be stretched vertically.

[The problem that the idea attempts to solve]

However, since the rear curtain as described above is manually raised and lowered, it is necessary to go to the mounting position each time the rear curtain is raised and lowered. Therefore, it has been impossible to raise and lower the rear curtain from the driver's seat while driving.

In addition, if the winding force is too strong for manually raised and lowered curtains, not only will it be difficult to pull up, but the curtain will wind up too quickly when you let go of it, causing the hooks at the ends to collide with the rear curtain storage case. There was a risk that the rear curtain or storage case would be damaged.

On the other hand, if the winding force is too weak, the winding will not take place even if the hand is released, resulting in poor operability.

Furthermore, such a structure can only be used in two ways: covering the entire surface of the rear window or not, and cannot be stopped at an intermediate position in the vertical direction of the rear window. Therefore, it was not possible to use the device appropriately depending on the angle of incidence of direct sunlight.

The purpose of the present invention is to overcome the above-mentioned problems and provide an electric rear curtain that can be raised and lowered electrically from a distance, and can be stopped at any position. do.

[Means to solve the problem]

The means of the present invention to solve the problem consists of a winding shaft that is attached to the back of the package tray and that always biases one end of the curtain in the winding direction by a spring force, and an electric motor that is attached to the other end of the curtain. a pulley provided in a housing within the moving body and driven by an electric motor; a wire wound around the pulley or rewound; a hook provided at the other end of the wire; An electric rear curtain device comprising: a locking tool provided near the upper end of a rear window and locking the hook;

[Operation] The wire is raised and lowered by locking the hook at the other end of the wire to a locking tool near the upper end of the rear window and operating the electric motor to wind up and unwind the pulley.

Therefore, a movable body attached to the other end of the curtain and containing an electric motor moves up and down, thereby raising and lowering the curtain. At this time, the winding shaft on the back of the rear package always biases one end of the curtain with a spring force, so the curtain is stretched under tension.

〔Example〕

Next, embodiments of the present invention will be described in detail based on the drawings.

As shown in FIG. 1, two winding shafts 4 (one winding shaft 4 is shown in FIG. 1) are located on the back side of a package tray 3 provided behind the rear seat 2 of an automobile 1. It is attached in the longitudinal direction of the tray 3. These winding shafts 4 are automatic winding shafts 4 having built-in springs 17, and are provided with protective covers 5a to protect the curtains 5. One end of the curtain 5 is biased in the winding direction by the winding shaft 4, and is normally wound up and stored within the protective cover 5a.

Further, the package tray 3 is provided with openings 6 for pulling out the curtains 5 of the two winding shafts 4, as shown in FIG.

The other end of the curtain 5 is held by a hollow cylindrical housing 8 containing an electric motor 7.

A moving body 18 has a structure in which an electric motor 7 is built into a housing 8. The electric motor 7 is configured to rotate forward or reverse by operating a switch 16 (see FIG. 2) provided at a driver's seat or the like.

As shown in FIG. 3, inside the movable body 18, an electric motor 7 is incorporated, and pulleys 10 are attached to the left and right shafts of the electric motor 7. The rotation directions of the pulleys 10 on both sides are made to be the same.

The pulley 10 is driven by the electric motor 7 to rotate forward or backward. Accordingly, the wire 9 wound around the pulley 10 is wound up or rewound, the length of the wire 9 can be adjusted, and the movable body 18 can be moved up and down. The wire 9 can be a thread, a thin plastic strip, a wire, or the like. A hook 11 is attached to the other end of the wire 9. The hook 11 is attached to a locking tool 12 shown in FIG. This locking tool 12 is attached by inserting its one end 12a into a garnish 14 attached to a rear window weather strip 13 above the package tray 3. 15 is a rear window.

In order to use the electric rear curtain 5 of this embodiment having such a configuration, first, the hooks 11 are attached to the locking tools 1.
Lock at 2. Switch 1 installed in the driver's seat, etc.
6 to rotate the electric motor 7 in the forward direction. Normal rotation refers to the rotational direction in which the curtain 5 rises, that is, the rotational direction in which the movable body 18 rises. Then, the pulley 10 in the movable body 18 rotates and the wire 9 is wound around the pulley 10, and the movable body 18
rises. Accordingly, the curtain 5 held by the movable body 18 is pulled out against the elastic force of the spring within the winding shaft 4. The curtain 5 that has been pulled out is tensioned with a certain tension, and the rear window 1
5 Cover the entire area. In this state, the rear window 15
This allows you to block sunlight from entering the vehicle interior.

Next, when storing the curtain 5 on the take-up shaft 4, the switch 16 is operated to reverse the electric motor 7. Reversal refers to the rotational direction in which the curtain 5 descends, that is, the rotational direction in which the movable body 18 descends. Then, the pulley 10 in the movable body 18 rotates, the wire 9 wound around the pulley 10 is pulled out from the movable body 18, and the movable body 18 descends. Along with this, the curtain 5 held on the moving body 18
is wound up by the elastic force of the spring within the winding shaft 4. At this time, hook 1 is attached to rear window 15.
Only the wire 9 that is locked to the locking tool 12 by the wire 1 is present. Therefore, rear visibility is not obstructed.

When the curtain 5 is not in use, the hook 11 can be removed from the locking tool 12, the curtain 5 can be wound up on the winding shaft 4, and the movable body 18 can be placed in the drawer opening 6 formed in the package tray 3. . In this case, since the movable body 18 is fitted into the drawer opening 6, it is possible to prevent noise from being generated inside the vehicle due to vibrations of the vehicle or the like.

In addition, the curtain 5 of the present invention has a rear window 15.
It can be stopped at any position in the vertical direction.

That is, this can be done by stopping the movement of the moving body 18 at an arbitrary position. Therefore, for example, the lower half of the rear window 15 may be covered, or the rear window 15 may be
It is possible to avoid covering the upper one-third of the area, and it can be selected and used as appropriate depending on the angle of incidence of direct sunlight.

In addition, although the above example shows an example in which the number of winding shafts 4 is two or less, this number is limited to the rear window 15 of an automobile.
There may be three or more depending on the shape and size. Further, in the above embodiment, the curtain 5 is used for a rear window 15, but it can be similarly used for a quarter window curtain 5, etc.

Further, although an example has been shown in which the locking tool 12 is attached to the garnish 14, it may also be attached to the ceiling of an automobile.

[Effect of idea]

The present invention achieves the following effects by having the above configuration.

(1) By locking the hook at the other end of the wire to the locking tool and driving the electric motor to rotate the pulley, the movable body attached to the other end of the curtain moves up and down, and the curtain moves up and down. Therefore, the curtain is reliably pulled out and stored, and stretched in the vertical direction of the rear window.

(2) Since the curtain is raised and lowered using an electric motor, the curtain can be raised and lowered simply by operating a switch, providing excellent operability. What's more, the curtains can be raised and lowered with a single switch without having to go near the curtains, so you can operate them from the driver's seat even while driving.

(3) Since the curtain is raised and lowered by driving an electric motor, the curtain can be stopped at any desired position, greatly expanding the ways in which the curtain can be used.

(4) Since the motor is incorporated into the moving body attached to the other end of the curtain, the structure is extremely simple, and changes to the body panel side can be minimized.

(5) Even if the electric motor fails, it can be operated manually.
