Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an electric rear curtain device for blocking direct sunlight that is inserted through a window glass of an automobile.

[Conventional technology]

In a car, direct sunlight may come in through the windshield when parking or in a traffic jam. Particularly in the summer, the temperature inside the vehicle compartment may be partly significantly increased.
Also, the lights of the following vehicles at night may become dazzling.
Therefore, various sunshades are attached to automobiles.

Among such awnings, a rear curtain is often used as one attached to the rear window side. This rear curtain is mounted on the package tray inside the rear window, and is stretched vertically with the ceiling interior material to block sunlight and lights that enter through the rear window.

The mainstream of such a rear curtain is a winding type that is biased in the winding direction. Then, the front end of the rear curtain is grasped and pulled up by hand, and the rear curtain is stretched in the vertical direction by being locked to the ceiling interior material.

[Problems to be solved by the device]

However, since the above-mentioned rear curtain is manually moved up and down, it is necessary to look back one by one or go to the back seat each time it is moved up and down, and operate it by hand with an uncomfortable posture, which is very troublesome. Moreover, there is a problem that the operation cannot be performed while driving.

In the case of manually raising and lowering, not only is it difficult to pull up if the winding force is too strong, but it is also suddenly wound up when you release your hand, and the hook at the tip collides with the storage case of the rear curtain. Could damage the rear curtain and storage case. On the contrary, if the winding force is too weak, there is a problem that the operability is poor because the film cannot be wound even when the hand is released.

Further, with such a structure, there are only two ways of use, that is, whether the entire surface of the rear window is covered or not, and it is not possible to stop the rear window at an intermediate position in the vertical direction. Therefore, it could not be used properly depending on the incident angle of direct sunlight.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the above-mentioned problems and to provide an electric rear curtain device capable of electrically raising and lowering a rear curtain from a distant position and further stopping the rear curtain at an arbitrary position. And

[Means for Solving the Problems]

Means for solving the problems include a winding shaft driven by an electric motor, which is attached to the back surface or front surface of a package tray and has one end of a curtain fixed, and a moving shaft attached to the other end of the curtain. Body, a pulley that is provided in the housing of the moving body and is always urged in the winding direction by a spring, a wire that is wound or unwound on the pulley, and a hook that is provided at the other end of the wire. And an engaging member which is provided near the upper end of the rear window and engages with the hook.

[Action]

The hook on the other end of the wire is locked to a locking tool near the upper end of the rear window to operate the electric motor. Then, the winding shaft rotates and the curtain is pulled out from the winding shaft or stored.

Along with this, the wire is wound around or rewound on the pulley urged by the spring force. At this time, a spring acts on the moving body in a direction in which the wire is always wound around the pulley, that is, in a direction in which the wire is always raised. Therefore, the curtain mounted between the moving body and the winding shaft is tensioned and stretched over the rear window.

〔Example〕

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 3, two winding shafts 4 are provided on the back surface of the package tray 3 provided behind the rear seat 2 of the automobile 1.
(One of the take-up shafts 4 is shown in FIG. 3), which is attached in the longitudinal direction of the tray 3. These take-up shafts 4 are driven by an electric motor 7, and a moving body 18 above the package tray 3 is moved.
The curtain 5 can be moved up and down by moving up and down. The wire 9 is attached to the moving body 18, and the hook 11 attached to the tip of the wire 9 is attached to the rear window 15
It is held by being locked to one end of a locking tool 12 provided on the.

As shown in FIG. 1, the electric rear curtain device of the present invention is provided with a winding shaft 4 on the back surface of the package tray 3.
It is designed to be rotated by an electric motor 7. The electric motor 7 can be normally or reversely rotated by a switching operation of a switch 16 (see FIG. 1) provided in a driver's seat or the like. Winding curtain 4 on winding shaft 4
A protective cover 5a is provided to protect the. Curtain 5
One end of the curtain 5 is attached to the winding shaft 4, and the other end of the curtain 5 is attached to the moving body 18.

In addition, as shown in FIG.
An outlet 6 of a curtain 5 of one winding shaft 4 is bored. The curtain 5 has a structure that moves up and down from the back surface of the package tray 3 to the front surface through the drawer opening 6.

The moving body 18 is a hollow cylindrical housing 8 and a spring 17.
And the pulley 10. A spring 17 is built in the housing 8, and pulleys 10 are attached to both ends of the spring 17. The spring 17 is always biased in the direction in which the wire 9 is wound around the pulley 10, that is, in the direction in which the curtain 5 is pulled upward.

The pulley 10 is normally or reversely rotated by driving the electric motor 7. Along with this, the wire wound around the pulley 10 is taken up or unwound,
The length of the wire 9 can be adjusted to move the moving body 18 up and down. As the wire 9, a thread, a thin plastic strip, a wire or the like can be used. A hook 11 is attached to the other end of the wire 9. This hook 11 is attached for locking to the locking tool 12 shown in FIG. The lock 12 is attached to the rear window weather strip 13 above the package tray 3.
It can be attached by inserting its one end 14 into. 15 is a rear window.

In order to use the electric rear curtain device of this embodiment having such a structure, first, the hook 11 is locked to the locking tool 12. By operating the switch 16 provided in the driver's seat or the like, the electric motor 7 is normally rotated. Here, the forward rotation means the rotation direction in which the curtain 5 rises, that is, the rotation direction in which the moving body 18 rises. Then, the pulley 10 in the moving body 18 rotates, and the wire 9 is urged by the spring 17
Rolled up to 10. Therefore, the curtain 5 becomes the winding shaft 4.
The wire 9 is wound around the pulley 10 by being pulled out from the wire 10, the wire 9 is shortened, and the moving body 18 rises,
The curtain 5 covers the entire rear window 15.

In this state, since the curtain 5 is pulled upward by the force of the spring 17, the curtain 5 is tensioned and stretched over the rear window 15, so that the sunlight that enters the passenger compartment can be blocked.

Curtain 5 that covers the entire rear window 15 as described above
To lower, operate switch 16 to move electric motor 7
Reverse. Here, the reverse rotation means the rotation direction in which the curtain 5 descends, that is, the rotation direction in which the moving body 18 descends. Then, the pulley 10 in the moving body 18 rotates against the force of the spring 17, the wire 9 wound around the pulley 10 is pulled out, the moving body 18 descends, and the curtain 5 attached to the moving body 18 is removed. It is wound around the winding shaft 4.
In this state, only the wire 9 locked to the locking tool 12 by the hook 11 exists in the rear window 15 and does not hinder the rear view. When lowering the moving body 18, that is,
When winding the curtain 5 on the winding shaft 4, the electric motor 7 is used.
The winding force of must be greater than the force of spring 17.

Also, when the curtain 5 is not used, the hook 11 is a locking device.
After removing from 12, the curtain is wound around the winding shaft 4 and the moving body 18 is placed on the drawer opening 6 formed in the package tray 3. In that case, since the moving body 18 is fitted in the outlet 6, it is possible to prevent the noise in the vehicle from being generated due to the vibration of the vehicle or the like.

Further, the electric curtain device of the present invention can stop the curtain 5 at any position in the vertical direction of the rear window 15. That is, the lifting and lowering of the moving body 18 can be stopped at an arbitrary position. This can be done by stopping the rotation of the electric motor 7 at an arbitrary position on the winding shaft 4 driven by the electric motor 7. Therefore, for example, it is possible to cover the lower half of the rear window 15 or not to cover the upper third of the rear window 15, and select and use it according to the incident angle of direct sunlight. can do.

In the above example, the number of winding shafts 4 is two or less, but this number may be three or more depending on the shape and size of the rear window 15 of the automobile. Further, although the curtain 5 for the rear window 15 is used in the above embodiment, the curtain 5 for the quarter window and the like can be used in the same manner.

Also, although the example in which the locking tool 12 is attached to the rear window weatherstrip 13 is shown, it may be applied to the ceiling of an automobile.
