Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a stopping device for a power window in a vehicle that is driven up and down by a window regulator equipped with a motor.

(Prior Art) In the case of a conventional window regulator, the vertical movement of the window glass is stopped when the load on the motor 10 for driving the window glass increases.

(Problems to be solved by the invention) Therefore, in the case of conventional window regulators, there is a problem in that a considerable stopping force is required to stop the window glass, and the window glass cannot be easily stopped. Ta.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a stopping device for a vehicle power window that can easily and accurately stop the window glass.

(Means for Solving the Problems) The stopping device for a vehicle power window of the present invention covers the edge of a window glass that is driven up and down by a motor from the lower end of the front edge to the rear edge of the upper edge. The electrically conductive detection body attached to the window glass is electrically conductively connected to a conductive plate attached in a glass run with which the front edge of the window glass comes into sliding contact when the window glass is raised and lowered, and the motor and the conductive plate are connected to It has a configuration in which it is connected via a controller incorporating a switch that opens the contact due to a change in capacitance when a part of the sensor comes into contact with the detection object.

(Function) The front edge of the window glass, which is driven up and down by a motor, is connected to a conductor plate attached to the glass run that slides into contact with the front edge of the window glass. When a part of the human body comes into contact with the detection object attached to the conductive plate, the contacts of a switch built into the controller that connects the motor and the conductive plate and activated by a change in capacitance open, causing the motor to rotate. The window glass stops moving up and down, and the movement of raising and lowering the window glass is stopped mid-way up and down.

(Example) Next, an example of the present invention will be described with reference to the drawings.

In a power window assembled to a door of a vehicle, a window regulator R installed in a door panel P to drive the window glass 1 up and down has a motor 2 connected to a battery (not shown) via a main switch, A sector gear 4 is rotatably supported on a base 3 attached to the door panel P and is rotated in forward and reverse directions by the forward and reverse rotation of the motor 2; It is equipped with an X-arm type lift arm 5 whose end is horizontally slidably connected to a guide member 6, and is attached horizontally to the lower end of the window glass 1, so that both ends of the lift arm 5 are horizontally slidable. The window glass 1 is connected to the window glass 1 via a guide fitting 7 that is movably connected, and the window glass 1 is fitted around the front and rear edges of the door panel P to guide the vertical movement of the window glass 1. It is raised and lowered by sliding on glass runs 8 made of elastic material fitted in a pair of front and rear glass channels 9, 9, which are vertically arranged parallel to the vicinity of the end and have a substantially U-shaped cross section. be moved.

A narrow film-like conductive detection body 10 is applied near the edge of the window glass 1 from the lower end of the front edge 1a to the rear end of the upper edge 1b, and is coated with, for example, a conductive paint mixed with metal powder. The movable terminal 11 is formed by painting or pasting a conductive metal foil tape, and is connected to the lower end of the movable terminal 11 and bent into a U-shape.
The lower end of the movable terminal 11 is fixed to the lower end while being held therebetween, and a contact piece 11a that projects downward is formed at the lower end of the movable terminal 11.

A strip-shaped conductive plate 12 is attached along the entire length of the inner surface of the glass run 8 in the front glass channel 9, and is attached to the inner surface of the glass run 8 in the front glass channel 9.
The movable terminal 11 comes into sliding contact with the conductive plate 12 by the vertical movement, and the conductive plate 12 and the detection body 10 are electrically conductively connected at each vertical position of the window glass 1.

The controller 13 detects the detection object 10 at the front edge 1a and upper edge 1b of the window glass 1 when a part of the human body is rising and falling.
The controller 1 is connected to the lower end of the conductor plate 11 in order to stop the rotation of the motor 2 when the controller 1
3 incorporates a high frequency oscillation circuit and a switch connected to the output side of the high frequency oscillation circuit and the motor 2, respectively, and a detection body 10 which becomes a touch electrode when the human body is connected to the input side of the high frequency oscillation circuit. When the human body comes in contact with the motor 2, the capacitance of the human body is added to the high frequency oscillation circuit, and the capacitance of the high frequency oscillation circuit changes, causing the contact of the switch to open and the motor 2
is stopped, and the raising and lowering operation of the window glass 1 is stopped midway through the raising and lowering.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, a conductive detection body 10 is attached to the edge of the window glass 1, which is driven up and down by the motor 2, from the lower end of the front edge 1a to the rear end of the upper edge 1b, and the window glass 1 is A conductive plate 12 attached to the glass run 8 with which the vicinity of the front edge 1a of the window glass 1 comes into sliding contact when the window glass 1 is raised and lowered.
The motor 2 and the conductor plate 12 are electrically conductively connected to each other through a controller 13 incorporating a switch that opens the contact due to a change in capacitance when a part of the human body comes into contact with the detection object 10. It is connected.

Therefore, if a human body comes into contact with the vicinity of the edge of the window glass 1 while the window glass 1 is being raised or lowered, the raising and lowering operation of the window glass 1 is immediately stopped, simplifying the operation to stop the window glass 1, and preventing the raising and lowering operation of the window glass 1. It can be stopped accurately.

In addition, since the detection object 10 attached near the edge of the window glass 1 is connected to the controller 13 via the conductor plate 12 attached to the glass run 8, the wiring from the detection section to the control section is compact. It is stored in
It is possible to avoid a problem in which the wiring gets caught in the movement of the window glass 1 up and down.

(Effects of the invention) In other words, the present invention includes a conductive detection body attached to the edge of a window glass that is driven up and down by a motor from the lower end of the front edge to the rear end of the upper edge; The front edge is electrically conductively connected to a conductor plate attached to the glass run that slides into contact with the glass run when moving up and down. By connecting via a controller that incorporates a switch whose contacts open when a change in the temperature of have an effect.
