DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for detecting the position of a door window panel in a power window apparatus of a motor vehicle, particularly a sashless door type vehicle.

[0002]

2. Description of the Related Art In a door in which a window panel is automatically raised and lowered by a power window regulator, when a foreign object is caught while the door window panel is being lifted, the power is detected by detecting a load of a power motor. There are known various types of devices in which the ascending drive of the window regulator is stopped or the drive is inverted to the descending drive to prevent foreign matter from being caught.

In a power window device having such a function of preventing foreign matter from being caught, a position detecting switch for detecting when the door window panel rises to a position near a fully closed position is provided on the door body. The detection function cancels the foreign substance trapping prevention function, so that the foreign substance trapping prevention function does not work even when the door window panel is fully closed and the load on the power motor increases.

[0004] This position detection switch is required to have a high mounting position accuracy in order to determine the foreign matter trapping prevention area of the door window panel, but in the case of a sashless door type vehicle,
Since the peripheral edge of the door window panel is in direct contact with the vehicle-side door weather strip attached to the vehicle-body opening edge and the required seal reaction force is generated, the fully closed position is set, and the components that constitute the power window regulator Of the position detection switch, it is difficult to obtain the mounting position accuracy of the position detection switch due to variations in the molding accuracy and the assembly accuracy of the above, and the assembly accuracy of the door window panel and the vehicle body side door weather strip.

On the other hand, Japanese Patent Application Laid-Open No. 7-259433 discloses a mounting structure for the above-described position detection switch, in which a position detection switch is disposed on a door side member so as to be vertically movable, while a member on a door window panel side is provided. An operating member that engages with the position detection switch when the door window panel is raised to move the position detection switch upward, and raises the door window panel to the fully closed position to adjust the position detection switch upward. A configuration in which the position detection switch is fixed at a position is disclosed.

[0006]

However, such a mounting structure of the slide adjustment type of the position detecting switch not only requires a large number of parts but is structurally complicated and disadvantageous in cost. It is unavoidable that the provision of the slide adjusting mechanism increases the size of the entire structure of the position detection switch, and makes it difficult to arrange the layout within the narrowly restricted door body.

SUMMARY OF THE INVENTION Accordingly, the present invention provides a door window panel position detecting device capable of improving the position detection accuracy of the door window panel by the position detecting switch without adjusting the mounting position of the position detecting switch.

The door window panel 10 is arranged so as to be able to move up and down in a slightly inclined state by a front guide rail 11 and a rear guide channel 12 fixed to the door inner panel 1A. The main arm 5 and the sub arm 7 are automatically moved up and down along the front guide rail 11 and the guide channel 12 by the expansion and contraction operation of the main arm 5 and the sub arm 7.

The drive circuit (not shown) of the power motor 4 detects the load of the power motor 4, and if the load exceeds a predetermined value, determines that a foreign object has been caught and stops or lowers the power motor 4. In addition, a foreign matter trapping prevention circuit for inverting driving is incorporated.

At the front end of the lower edge of the door window panel 10 and at the rear end of the main channel 8, window-side stoppers 13 are provided, while the waist reinforcement 15 of the door inner panel 1A also has two front and rear doors. A stopper 14 is provided, and the fully closed position of the door window panel 10 is regulated by engagement of the window-side stopper 13 and the door-side stopper 14.

As shown in FIG. 3, the door-side stopper 14 has a vertically long hole 15a formed in the waist reinforcement 15.
And the door-side stopper 14 is vertically adjusted in its mounting position within the length range of the elongated hole 5a.
However, at the position where the peripheral edge thereof is raised to a state in which a required sealing reaction force is obtained by directly contacting the vehicle body side door weather strip mounted on the vehicle body opening edge (not shown), a window is formed in the door side stopper 14. The side stopper 13 is engaged to regulate the fully closed position of the door window panel 10.

Reference numeral 20 denotes a position detecting switch for detecting a predetermined ascending position of the door window panel 10 and canceling the operation of a foreign object trapping prevention circuit in the drive circuit of the power motor 4 based on the detected signal. The detection switch 20 is provided at one of the window-side stopper 13 and the door-side stopper 14, for example, at the door-side stopper 14.

On the other hand, when the door window panel 10 is raised on the window side stopper 13, it engages with an arm 21 as an actuated part for opening and closing the contact of the position detection switch 20 near the fully closed position, An arm pusher 22 is provided as an operating body for rotating the arm portion 21 to operate a switch.

The position detection switch 20 is a door-side stopper 1
4 is fitted to a holder 23 fixed by rivets 24, and snap portions 20a provided on upper and lower surfaces are engaged with and fixed to snap holes 23a provided on upper and lower walls of the holder 23.

As shown in FIG. 4, the arm portion 21 of the position detection switch 20 is set at the initial position a at the position of the arm pusher 2.
When the front end of the door window panel 10 is engaged and turned upward, the contact point is located at a predetermined near-closed position before the fully closed position of the door window panel 10, for example, at a turning position b corresponding to a position 4 mm before the fully closed position. The arm pusher 22 can be freely rotated along with the upward movement of the arm pusher 22 with the contacts being turned on to a rotation position c corresponding to the fully closed position of the door window panel 10 after that.

The lower end of the arm pusher 22 is joined to the window-side stopper 13, and an end cap 22a made of a synthetic resin material such as nylon is fitted at the tip.

The door window panel 10 slightly rolls in the front-rear direction by a clearance set between the front guide rail 11, the guide channel 12, and a slider (not shown). Since the window panel 10 is moved up and down while slightly tilting backward, the door window panel 10 tends to roll backward.

For this reason, the window side stopper 1
The rear window side stopper 13 of the door window panel 10 is provided below the substantially center of gravity of the door window panel 10, while the rear side door stopper 14 of the door side stoppers 14 is Stopper 13
Is provided on the vertical trajectory line, so that even if the door window panel 10 falls backward when ascending, the engagement load is not excessively restricted and the fully closed position is regulated.

Therefore, in this embodiment, the position detection switch 20 is provided on the rear door stopper 14 on the rear side, while the arm pusher 22 is provided on the window side stopper 13 on the rear side, so that the arm portion 21 and the arm pusher 22 are provided.
When the door window panel 10 is tilted in the rearward rolling direction when the door window panel 10 is raised, the door window panel 10 is not affected by the vertical displacement due to the tilt. It is set below the center of gravity.

As described above, since the door window panel 10 has a slightly upward and downward moving trajectory inclined backward, the arm portion 21 and the arm pusher 22 are arranged to protrude behind the door-side stopper 14 and the window-side stopper 13. Then, as the door window panel 10 rises,
The point of engagement between the arm 1 and the arm pusher 22 can be moved toward the free end of the arm 21.

According to the structure of the above embodiment, when the door window panel 10 is raised by operating a window opening / closing switch (not shown), a period from the fully opened position until the position detection switch 20 is operated as described later. If the load on the power motor 4 of the power window regulator 2 exceeds a predetermined value in the foreign matter trapping prevention region, it is determined that the foreign matter is trapped and the drive of the power motor 4 is stopped, or the drive is reversed and lowered. Thus, the function of preventing foreign matter from being trapped is obtained.

When the door window panel 10 rises to the vicinity of the fully closed position, the tip of the arm pusher 22 provided on the window side stopper 13 engages with the arm 21 of the position detection switch 20 provided on the door side stopper 14. When the arm 21 is pivoted upward from the initial position a, and the arm 21 is pivoted to the contact input position b corresponding to a raised position 4 mm before the fully closed position of the door window panel 10, the arm 21 is moved to the position. The detection switch 20 is turned on (for example, turned on), and sends a cancel signal to the foreign substance trapping prevention circuit incorporated in the drive circuit of the power motor 4 to cancel the foreign substance trapping prevention function.

The arm 21 is provided on the door window panel 10.
Can be freely rotated with the contacts turned on to a turning position c corresponding to the fully closed position of the door window panel 13 and the door-side stopper 14 and the window-side stopper 13 are engaged from the contact turning position b.
