Description

[Detailed Description of the Invention] This invention relates to a side window glass suction prevention device for preventing the side window glass of an automobile from being sucked out.

Even if the side window glass of a car is closed, when the vehicle speed increases, there is a phenomenon in which the side window glass is sucked out by the negative pressure generated on the outside of the side window glass. When this phenomenon occurs, even if the side window glass is closed, a gap is created between the side window glass and the car body, and outside air enters the cabin through this gap, causing unpleasant noise. There was a drawback.

Therefore, as shown in Japanese Patent Application Laid-open No. 58-20514 (automobile window frame structure) and Utility Model Application No. 57-114071 (door glass support structure), when the door is closed, the closed door glass Consideration has been given to preventing the door glass from being sucked out during high-speed driving by effectively bringing a weather strip on the outside of the vehicle into close contact with the periphery of the vehicle, or by forcibly pressing down on the door glass from the outside. There is.

However, in these conventional glass suction prevention devices, if the biasing mechanism that holds the glass does not release due to some reason when opening the door glass, the door glass is not held by the biasing mechanism. If the door glass is forced to open in this state, problems such as a sliding noise occurring between the glass retainer and the door glass and an unreasonable load being placed on the power window motor arise.

This idea was created in view of the problems mentioned above. For example, even when the speed of the car is very high, the side window glass will not be sucked out to the outside and a gap will be created between it and the car body. It is an object of the present invention to provide a side window glass suction prevention device that can prevent the door glass from opening while being pressed by the glass presser. .

That is, in the suction prevention device configured in this way, for example, when the glass presser lever 16 is unlocked and the side window glass 11
The following describes the operation when both doors are closed and the vehicle speed is above a certain speed. In this case, the lock switch 21, the glass close switch 23
Both door close switches 24 are opened and output "H" level signals through the respective low pass filters 22a to 22c, and the vehicle speed detection circuit 26 also outputs "H" level signals. This allows the first

This becomes a level signal and supplies an “H” level signal to the motor forward/reverse drive circuit 37. In other words, the lock motor 14 rotates in the direction of arrow a in FIG.
At the same time, the gear 15 also rotates in the direction of the arrow a. This rotation of the gear 15 causes the glass presser lever 16 to rotate from the position shown by the broken line to the position shown by the solid line. When the glass holding lever 16 is rotated to the position shown by the solid line, the side window glass 11 is prevented from being sucked out in the direction of the arrow b. In other words, the side window glass 11 is attached to the glass holding part 1 of the glass holding lever 16.
Locked by 8. As a result, the lock switch 21 in FIG. 2 is closed and the first AND gate AND ₁ is closed.
outputs an “L” level signal, and the lock motor 38
stops.

By the way, when the side window glass 11 is locked by the glass holding portion 18 of the glass holding lever 16, the unlock switch 27 opens. As a result, an "H" level signal is supplied to one terminal of the fourth AND gate _AND4 . In this way, when the side window glass 11 is locked, if the glass opening operation switch 29, which is operated when opening the side window glass 11, or the door opening operation switch 34, which is operated when opening the door, is closed. , 3rd Nand Gate
The output of NAND ₃ changes from "L" level to "H" level. As a result, the flip-flop 36
is set and its Q output becomes "H" level. Therefore, since the "L" level signal is input to the first NAND gate NAND ₁ , its output becomes "H" level, and the fourth AND gate
The output of AND ₄ becomes "H" level. Note that when the vehicle speed falls below a certain value, the output of the vehicle speed detection circuit 26 becomes "L" level, and the second AND gate AND ₂
The output becomes "L" level. Therefore, even if the Q output of the flip-flop 36 is at the "L" level, when the vehicle speed falls below a certain value, the first NAND gate is activated.
The output of NAND ₁ becomes "H" level, and the output of the fourth AND gate AND ₄ also becomes "H" level. In other words, when the side window glass 11 is opened, the door is opened, or the vehicle speed drops below a certain value, the fourth
The output of the AND gate _AND4 becomes "H" level, and the motor forward/reverse drive circuit 37 is activated. In other words,
The lock motor 14 rotates in the direction opposite to arrow a in FIG. Therefore, the gear 15 also rotates in the opposite direction to the arrow a. Further, due to the rotation of the gear 15, the glass presser lever 16 is rotated from the position shown by the solid line to the position shown by the broken line. As a result, the side window glass 11 is moved by the glass holding lever 16.
The lock by the glass holding part 18 is released.
In this case, since the unlock switch 27 is closed, the output of the fourth AND gate _AND4 changes from the "H" level to the "L" level. As a result, flip-flop 36 is reset. Further, the lock switch 21 is opened and the first AND gate is opened.
The output of AND ₁ becomes "L" level. Eventually, the motor forward/reverse drive circuit 37 ceases to operate, and the lock motor 14 stops.

Here, when the glass opening operation switch 29 is closed, that is, when the side window glass 11 is opened, when the lock by the glass holding part 18 is released and the unlocking switch 27 is closed, the NOR gate NOR receives an "H" level signal. , and the electromagnetic relay switch 30 is driven by the relay drive circuit 33. This causes the power window motor 31 to operate and the side window glass 11 to open.

As described above, according to this invention, when the vehicle speed is above a certain speed, the side window glass is closed, and the door is closed, the biasing mechanism that prevents the side window glass 11 from being sucked out is activated, and the vehicle speed is maintained at a constant speed. Since the operation of the biasing mechanism is canceled in response to the following or when the side window glass 11 is opened or the door is opened, even if the speed of the car is very high, for example, the side window glass It is possible to prevent the air from being sucked out to the outside and to prevent a gap from forming between itself and the vehicle body, thereby eliminating unpleasant noises. Furthermore, since the side window glass is opened in response to the release of the biasing mechanism, it is possible to prevent the side window glass from opening while being pressed by the biasing mechanism. .
