Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automobile sunroof that is equipped with a sunshade and that is electrically opened and closed.

(Prior Art) Some automobile sunroofs have a sunshade that can be opened and closed separately from the sunroof.

With conventional automotive sunroofs, it is difficult to tell from the inside of the vehicle whether the sunroof is open or closed, especially if the sunroof is tilted up and the sunshade is closed. There was a risk of getting out of the car with the door open, and when it rained, rain would get into the car, which was undesirable from a theft-prevention standpoint.

(Problems to be Solved by the Invention) The present invention has been made by focusing on such conventional problems.When the sunshade is in the closed position, the sunroof is always in the closed position. The purpose is to solve problems.

(Means for solving the problem) The gist of the present invention to achieve this purpose is as follows:
In a car sunroof equipped with a sunshade, in which the sunroof is opened and closed by an electric motor, a sunshade closed position detection switch that operates when the sunshade is fully closed is installed at the end of the sunshade's movement trajectory on the closed position side. When the sunshade is closed and the sunshade closed position detection switch is activated, a reverse drive circuit rotates the motor to drive the sunroof in the closing direction, and when the sunshade is in the closed position, the sunshade closed position detection switch is activated. A sunroof for an automobile, characterized in that the motor drive circuit is provided with a forward rotation drive circuit that disables energization to the motor and disables driving the sunroof in the opening direction when the sunroof is in the closed position. It consists in a device to prevent forgetting to close the door.

(Function) In the device for preventing forgetting to close the sunshade having the above configuration, the sunroof cannot be opened when the sunshade is in the closed position, and when the sunshade is closed, the sunroof is also closed electrically. The sunroof is always placed in the closed position.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 4 show an embodiment of the present invention.

As shown in FIGS. 1, 3, and 4, a sunroof 3 and a sunshade 4 are attached to a roof 2 of an automobile 1 for opening and closing a roof opening 2a. The sunroof 3 is configured to be electrically opened and closed between a closed position shown in FIG. 3 and an open position (tilt-up position) shown in FIG. 4. That is, the sunroof 3 is connected to a cable 5 that is routed around the roof opening 2a and is driven by a motor M shown in FIG. 2, and is driven in the opening direction by normal rotation of the motor M. is tilted up, and driven in the closing direction (tilted down) by the reverse rotation of the motor M.

On the other hand, the sunshade 4 can be manually opened and closed between the closed position shown in FIG. 3 and the open position shown in FIG. 4.

As shown in FIG. 2, the drive circuit 6 of the motor M
In the figure, 7 is a power source, and 8 and 9 are first and second relays, respectively.

The first relay 8 includes a coil 81 and a switch 82.
When the coil 81 is energized, the switch 82 switches from the ground terminal 82a to the power supply terminal 82b, thereby closing the normal rotation circuit of the motor M.

Similarly, the second relay 9 consists of a coil 91 and a switch 92, and when the coil 91 is energized, the switch 92 switches from the ground side terminal 92a to the power side terminal 92b, and reverses the rotation of the motor M. Close the circuit.

The forward rotation drive circuit 8a that energizes the coil 81 and closes the normal rotation circuit includes an open side terminal 10a of the operating switch 10, a first switch portion 11a of the sunshade closed position detection switch 11, and a sunroof open detection switch. The switch 12 is connected in series.

On the other hand, in the reverse drive circuit 8b, which energizes the coil 91 and closes the reverse circuit, the operation switch 1
The closing side terminal 10b of 0 and the second switch section 11b of the sunshade closed position detection switch 11 which switches in conjunction with the first switch section 11a are connected in parallel, and the closing side terminal 10b and the second switch section 11b are connected in parallel. A sunroof close detection switch 13 is connected in series.

Each switch part 11a, 11b of the sun shade closed position detection switch 11 is provided at the end of the movement trajectory of the sun shade 4 on the closed position side so as to be able to detect that the sun shade 4 is in the closed position.
It is designed to be opened and closed by the engaging end 4a of the sunshade 4. That is, Sunshade 4
When is in the closed position, the first switch part 11a is open, the second switch part 11b is closed,
When the sunshade 4 is in the open position, the first switch section 11a is closed and the second switch section 11b is open.

Regarding the sunroof open detection switch 12 and the sunroof close detection switch 13, the sunroof 3
is in the open position, the open detection switch 12
is open and the closing detection switch 13 is closed. When the sunroof 3 is in the closed position, the opening detection switch 12 is closed and the closing detection switch 13 is open.

In the automobile sunroof forgetting-to-close prevention device having the above configuration, when the sunroof 3 and sunshade 4 are both in the closed position as shown in FIG. 3, the first switch portion 11a is open.
Even if the operation switch 10 is switched to the open terminal 10a, the switch 82 of the first relay 8 remains switched to the ground terminal, the normal rotation circuit of the motor M is not closed, and the motor M is stopped. There is. Therefore, sunroof 3 does not open.

When the sunshield 4 is opened in the state shown in FIG. 3, the first switch portion 11a is closed, so when the operating switch 10 is switched to the open side terminal 10a, the forward rotation drive circuit 8a is closed, and the first relay 8 The coil 81 is energized, and the switch 82 connects the power supply side terminal 8.
2b, the normal rotation circuit is closed, the motor M rotates in the normal direction, the cable 5 is driven, and the sunroof 3 is opened (tilted up). When the sunroof 3 is displaced to the open position, the sunroof open detection switch 12 is opened and the motor M is stopped.

When the sunshade 4 is closed in the state shown in FIG. 4, the second switch portion 11b is closed. At this time, since the close detection switch 13 is closed, the reverse drive circuit 8b is closed, and the second relay 9
The coil 91 is energized, the switch 92 is switched to the power supply terminal 92b, the reversing circuit is closed, the motor M is reversed, the cable 5 is driven in the opposite direction, and the sunroof 3 is closed (tilted). down). When the sunroof 3 is displaced to the closed position, the close detection switch 13 is opened and the motor M is stopped.

Also, when the operating switch 10 is switched to the closing terminal 10b in the state shown in FIG. 4, the motor M rotates in reverse in the same manner as described above, and the sunroof 3 closes.

(Effect of the invention) With the device for preventing forgetting to close a sunroof for an automobile according to the present invention, the sunroof cannot be opened when the sunroof is in the closed position, and when the sunroof is closed with the sunroof open, the sunroof is closed. Since the sunroof is driven in the same direction, it is possible to reliably prevent forgetting to close the sunroof.
