Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an electric sunroof device for an automobile, and particularly to a safety device when the sunroof is closed.

(Prior Art) In general, an electric sunroof device for a car is an opening provided in the roof of the car that can be opened and closed by a lid member operated by a motor, allowing sunlight to enter the cabin of the car. be.

By the way, in conventional electric sunroof devices, once the motor switch for operating the motor is operated, the lid member continues to operate until the opening is completely opened or closed. If the person in the passenger seat were to stick their hands or head out of the roof opening without noticing this, there was a risk that their hands or head would get caught between the periphery of the opening and the lid member. .

Therefore, in order to solve this problem, as described in Japanese Unexamined Patent Application Publication No. 55-145019, a detection plate is arranged around the opening of the roof and on one side of the sliding roof. Some devices are equipped with a detector that operates in conjunction with the detection plate when an obstacle comes into contact with it.

However, this method increases the number of parts, reduces the effective area of the opening, and furthermore, even if a person simply tries to put his or her head out of the opening, there is a problem that the detection plate is likely to come into contact with the detection plate, resulting in malfunction. Ta.

There is also another conventional device in which the lid member is temporarily stopped before the roof opening is completely closed, and then when the motor switch is operated again, the lid member completely closes the opening. This device had the disadvantage that the switch operation was complicated.

(Purpose of the invention) This invention was devised in view of the conventional problems as described above, and the object is to provide an electric sunroof device for an automobile that improves safety without complicating switch operations. It is an object.

(Invented tank bottom) The structural features are that the wind deflector member, which rises and falls in conjunction with the opening/closing operation of the sunroof lid member, is supported so as to be slidable back and forth, and this wind deflector member also slides forward. A switch member is provided that is activated when the wind deflector is moved, and when a foreign object inserted into the opening of the roof comes into contact with the wind deflector member, the switch member is activated to stop power supply to the motor.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a roof panel of an automobile. A substantially rectangular opening 2 is formed in the roof panel 1, and a lid member 3 is provided in the opening 2 so as to be slidable in the front and rear directions.

An outer peripheral portion 5e of a frame 5 is fixed to the peripheral edge of the opening 2 of the roof panel 1 via a reinforcing plate 4 disposed on the indoor side.

This frame 5 has a rectangular shape with an indoor opening 5a corresponding to the opening 2 in the center, and almost all the space is between an inner flat part 5d of the outer peripheral part 5e and a peripheral edge 5f of the opening 5a. A protrusion 5d is formed around the periphery.

A bracket 6, which is a wind deflector support member, is arranged on the upper surface of the front part of the protrusion 5d facing the opening 2. A horizontal part 6b in the center with a part bent vertically forward, and this horizontal part 6
It consists of a planar L-shaped part 6c with the tip of b bent downward and its right end bent forward.

The bracket 6 is slidably provided in the front and rear directions relative to the frame 5 by inserting a pin 7 into a long hole 6d bored in the horizontal portion 6b and fixing the pin 7 to the protruding portion 5d. It is being

In addition, the vertical portion 6a of the bracket 6 and the protruding portion 5 of the frame 5
A chevron-shaped leaf spring 8 is disposed in the vehicle width direction between the front and rear wheels d, and the bracket 6 is attached to the rear of the leaf spring 8.

Further, a wind deflector 10 is attached to the bracket 6 via a shaft 9 inserted through the L-shaped portion 6c, and this shaft 9 is connected to a stay 12 disposed on the side of the opening 2. The deflector 10 is designed to rise and fall in conjunction with the opening and closing movement of the lid member 3. That is, when the stay 12 rotates upward, the wind deflector 10 is moved to the third position by the spring force of the spring 11 attached to the shaft 9. It is erected to the upright position shown by the dashed line in the figure, and when the stay 12 rotates downward, it is stored in the retracted position shown by the solid line in the figure.

When stored, the rear end of the wind deflector 10 projects further rearward than the front edge of the opening 5a of the frame 5.

Also, "a stop switch 13 is provided below the protrusion 5b at the front of the room 5, and the switch knob 13a of this stop switch 13 is inserted through the through hole 5c of the inclined part of the protrusion 5b." The stop switch 13 is brought into contact with the vertical portion 6a of the bracket 6, and is thus turned on and off by the sliding movement of the bracket 6.

Further, the peripheral edge 5f of the opening 5a of the frame 5 is fixed together with the peripheral edge of the opening of the top sealing 14 disposed below the roof panel 1 by a seaming welt 15.

On the other hand, the lid member 3 has a frame 17 on the lower side of the panel 16.
It is formed by fixing the trim 18 through the lid member 3, and an elastic member 19 is attached to the outer periphery of the lid member 3.

FIG. 4 shows a circuit for operating the lid member 3,
In the figure, 20 is a motor that opens the lid member 3 by rotating it in the forward direction, and closes the lid member 3 by rotating it in the reverse direction, and 21 is connected to the battery 23 via the fuse 22 and the stop switch 13. This motor switch 21 rotates the motor 20 in the forward direction when the interlocking contacts 21a and 21b are on the terminals a and c,
When the terminals are on the d side, the motor 20 is rotated in the opposite direction.

Next, the effects will be explained.

In order to open the opening 2 in this electric sunroof device, the contacts 21a and 21b of the motor switch 21 are pushed toward the terminals a and c.

Then, the motor 20 rotates forward, and the lid member 3 slides rearward to open the opening 2.

To close the opening 2 opened as shown in "-", the contacts 21a and 21b of the motor switch 21 are moved toward the terminal bd.

Then, the motor 20 rotates in the opposite direction, and the lid member 3 slides forward to close the opening 2.

At this time, when the lid member 3 has slid a predetermined distance from the fully open position, the stay 12 is pushed by the lid member 3 and rotates downward, and the wind deflector 10 moves as shown by the solid line in FIG. The lid member 3 smoothly and completely closes the opening 2.

By the way, if a hand or the like is caught between the wind deflector 10 and the lid member 3 while closing the opening 2, the wind deflector 10 receives a forward force from the hand, and the bracket 6 It slides forward against the leaf spring 8.

Then, the stop switch 13 is turned off, cutting off the motor switch 21 and the battery 23, and power supply to the motor 20 is stopped.

Rotation of motor 20 stops.

Then, when the hand is removed from between the wind deflector 10 and the lid member 3, the bracket l-6 slides backward by the spring force of the spring 8, the stop switch 13 is turned on again, and the power supply to the motor 20 is restarted. , the motor 20 rotates again, thereby closing the opening 2.

In this device as described above, when a part of the body such as a hand is caught between the wind deflector and the lid member, the stop switch is turned off and the rotation of the motor is stopped. It can prevent injuries and greatly improve safety.

Furthermore, simply by removing the hand between the wind deflector and the lid member, the rotation of the motor is restarted and the lid member is closed, so the switch operation is very simple as in the conventional case.

Furthermore, the device of this embodiment has the following effects compared to the device described in the above-mentioned conventional publication.

■ There is no need to provide a separate feeler, so the number of parts is small.

■ The conventionally installed wind deflector is used as a feeler, so it looks just as good as a conventional sunroof device.

■ There is nothing protruding into the opening, so the opening will not be narrowed.

■ The touch sensor of this device is located so that it does not get in the way of the occupants when the roof is opened or closed.

■ The hand or head is caught between the lid and the front edge of the opening, and only at that time is the tactile element brought to the operating position, so there is no malfunction in this device.

FIG. 5 shows an operating circuit of a second embodiment of the present invention. In this embodiment, unlike the above embodiment, a stop switch 13 is provided to cut off the terminal d of the motor switch 21 and the battery 23. contact 21 of motor switch 21
The stop switch 13 stops power supply to the motor 20 only when the terminals a and 21b are turned toward the terminals A and D and the motor 20 is rotating in reverse.
