Description

  The present invention relates to an X-arm type window regulator that raises and lowers a vehicle window glass.

  In general, a sliding door having a lifting window is installed on the side surface of a one-box vehicle. However, if the sliding door is opened with the window glass open, a child may get caught from the window or get out of his arm, and it will be caught between the side frame of the entrance / exit and the window frame, resulting in a serious accident. There is a worry that will occur.

  Conventionally, with respect to a sliding door of a vehicle, a pivotable lift arm whose one end is connected to a window glass and the other end is linked to a drive source, and is linked to the lift arm and can be moved integrally with the pivoting movement of the lift arm. The movable body has a movable body and a detection member that operates in accordance with the movable operation of the movable body. The window glass is moved up and down by the pivoting operation of the lift arm, and the movable body is movable according to the pivot angle of the lift arm. 2. Description of the Related Art A window opening / closing device for a sliding door for a vehicle that detects an open state of a window that is opened / closed by raising / lowering a window glass by the operation of a detection member is known (patent documents 1 to 5).

The window opening / closing device of the vehicle sliding door is slidable in the vehicle front-rear direction along the side of the vehicle body to open and close the window, and the window opening for detecting the opening state of the window. The stopper mechanism is connected to the detection mechanism and the window opening detection mechanism via a cable, and restricts sliding in the vehicle front-rear direction when the window is opened.
In such a sliding door, when the window glass does not completely close the window portion, even if the sliding door is opened, the sliding door is not completely opened, that is, half opened. , Informing passengers that the windows are open and preventing accidents.

In order to achieve the function described above, a window opening detection mechanism is attached to the window regulator mechanism, and a stopper mechanism is attached to a lower guide roller guided by a lower guide rail provided in the vehicle body with respect to the lower end of the slide door, The window opening detection mechanism is coupled to a stopper mechanism via a connection cable.
In such a mechanism, the window opening detection mechanism detects the position of the lift arm coupled to the drive device of the window regulator mechanism, and the connection member is pulled by detecting the position of the lift arm to stop the stopper member of the stopper mechanism. The position of is changed.

For example, when the window glass is descending, the stopper member comes into contact with the vehicle body while the sliding door slides backward in the vehicle, that is, in the half-open state of the door, and the sliding door further slides backward. Stopped.
Also, when the window glass has completely closed the window, the window opening detection mechanism changes the position of the stopper member via the cable, allowing further sliding to the rear of the sliding door, A fully open state of the sliding door is obtained.

JP 2002-013349 A Japanese Patent No. 3786596 JP 2007-154656 A Japanese Patent No. 3931453 Japanese Patent No. 3931537

However, in the conventional window opening / closing device for a sliding door for a vehicle, a window opening detection mechanism (cam plate and detection lever) is attached to the window regulator mechanism (additional components are added), or the cam plate and detection lever By changing the shape, the position of the lift arm corresponding to the opening of the window glass (opening of the window) was detected.
Therefore, conventionally, since the position of the lift arm corresponding to the opening of the window glass is changed by changing the size of the window, it is necessary to change the number of components and the shape of the cam plate and the detection lever. As a result, there were problems such as having to change the assembly process.
Moreover, it is necessary to be able to easily cope with both types of doors that need to detect the opening of the window, such as sliding doors, and doors that do not need to detect the opening of the window.

  Therefore, the present invention has an object to solve the above-described problems of the prior art, and can detect the opening of the window without significantly changing the assembly process, and needs to detect the opening of the window. An object of the present invention is to provide a window regulator that can easily cope with both types of doors and doors that do not need to detect the opening of the window.

  The present invention includes a lift arm that is pivotally attached to the vehicle body via a shaft, and an equalizer arm that is pivotally attached to the lift arm, and a driven gear that meshes with a drive mechanism at one end of the lift arm. Fixed, one end of the equalizer arm is engaged with a fixed guide channel fixed to the vehicle body so as to be movable in the axial direction, and the other end of the lift arm and the other end of the equalizer arm are lifted to support the window glass. In order to solve the above-described problem, a window regulator that is movably engaged with a guide channel in the axial direction thereof is fixed so that the shaft is rotated in conjunction with the lift arm, and a switch is disposed adjacent to the shaft. Install and change the shape of the cross section of the shaft over a certain angle in the circumferential direction at the part adjacent to the switch, The outer periphery of the shaft away against the said switch in accordance with the rotation, by switching the ON / OFF of the switches, the angle of the lift arm, i.e., detects the position of the window glass.

  The window glass is provided on the sliding door of the vehicle body, and a stopper device for restricting the opening of the sliding door is installed, and an ON / OFF signal of the switch is transmitted to the control device of the stopper device. The stopper device may be released when the window glass is in the closed position, and the stopper device may be operated when the window glass is in another position.

According to the present invention, it is possible to reliably detect the position of the window glass simply by changing the shape of the shaft and installing a switch, so the number of parts and the shape of the parts can be compared with those that do not need to detect the position of the window glass. There are few differences, no significant changes in the assembly process are required, and the cost is low.
Moreover, it can respond easily to any door which needs to detect the opening degree of a window part, and the door which does not need by the presence or absence of a switch.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a window regulator installed on a sliding door of a vehicle body, FIG. 2 is an exploded perspective view of main parts of the window regulator, and FIG. 3 is a perspective view of main parts of the window regulator.
The window regulator of this embodiment is for raising and lowering a vehicle window glass. As shown in FIG. 1, a lift arm 1, an equalizer arm 2, a driven gear 3, a fixed guide channel 4 and an elevation guide channel 5 are provided. Prepare.

The lift arm 1 and the equalizer arm 2 intersect with each other at an intermediate portion thereof and are axially attached. A driven gear 3 is fixed to one end of the lift arm 1.
The driven gear 3 is driven by a drive mechanism 6 installed on a slide door of the vehicle body. The drive mechanism 6 has a motor 7 and a pinion 8 connected to the output shaft of the motor 7, and the driven gear 3 is engaged with the pinion 8.
Rollers are rotatably mounted on the other end of the lift arm 1 and the both ends of the equalizer arm 2, respectively.
A roller attached to one end of the equalizer arm 2 is engaged with the fixed guide channel 4 so as to be movable in the axial direction.
The roller mounted on the other end of the lift arm 1 and the roller mounted on the other end of the equalizer arm 2 are engaged with the lifting guide channel 5 so as to be movable in the axial direction.

The fixed guide channel 4 is attached to the door of the vehicle body along the front-rear direction, and the lifting guide channel 5 supports the lower end of the window glass.
Therefore, when the motor 7 is operated to rotate the pinion 8, the driven gear 3 meshed with the pinion 8 rotates, and the other end of the lift arm 1 fixed to the driven gear 3 rotates up and down. Then, the other end of the equalizer arm 2 pivotally attached to the lift arm 1 also rotates up and down. As a result, the raising / lowering guide channel 5 moves up and down, and the window glass supported by the lifting guide channel 5 moves up and down.
Further, as the lifting guide channel 5 moves up and down, the roller engaged with the lifting guide channel 5 moves, and the roller engaged with the fixed guide channel 4 also moves.
The above structure is the same as that of the conventional X arm type window regulator.

In the present embodiment, although not shown, a stopper device for restricting the opening of the slide door is installed on the vehicle body.
As shown in FIG. 2, the lift arm 1 is mounted on a base plate 9 fixed to the slide door via a shaft 10. The shaft 10 passes through the base plate 9 in a rotatable manner, and one end portion of the shaft 10 protruding from the surface of the base plate 9 is fixed to the lift arm 1 by caulking. Therefore, when the lift arm 1 rotates, the shaft 10 also rotates by the same angle.

  As shown in FIG. 3, a switch 11 is installed on the back surface of the base plate 9 adjacent to the other end of the shaft 10, and the movable terminal 12 of the switch 11 is moved away from a fixed terminal (not shown) provided on the switch body. It is biased to approach the shaft 10. Then, when the movable terminal 12 contacts or separates from the fixed terminal, the switch 11 is turned ON / OFF, and the electrical signal is transmitted to the control device of the stopper device.

The cross section of the shaft 10 is basically circular, but the portion adjacent to the switch 11 (in this embodiment, the other end of the shaft 10) has a large diameter portion over a certain angle in a part of the circumferential direction. 13 is formed. The angle at which the large-diameter portion 13 is formed is equal to the angle at which the lift arm 1 rotates in order to raise and lower the window glass from the opening start position to the fully open position.
Further, when the window glass is at the intermediate position and the fully opened position of the lifting limit, the large diameter portion 13 faces the movable terminal 12 of the switch 11, and when it is in the closed position, the large diameter portion 13 is the movable terminal. 12 is off.

As shown in FIG. 4, when the large-diameter portion 13 faces the switch 11, the movable terminal 12 is pressed against the outer periphery of the large-diameter portion 13 to contact the fixed terminal, and the switch 11 is turned on. . Then, the control device of the stopper device receives the electric signal from the switch 11 to operate the stopper device and restricts the opening of the slide door. Therefore, the sliding door cannot be completely opened, and a pinching accident caused by opening the sliding door while the window is open can be prevented.
On the other hand, as shown in FIG. 5, when the large diameter portion 13 is detached from the switch 11, the movable terminal 12 is separated from the fixed terminal by the biasing force, and the switch 11 is turned off. Then, the control device of the stopper device receives the electric signal from the switch 11 and releases the stopper device. Therefore, the sliding door can be opened when the window is closed.

When the door of the vehicle body is not a sliding door, the switch 11 is not installed because a stopper device for restricting the opening of the door is unnecessary. In this case, the other structure does not need to be changed from when the stopper device is installed.
The cross-sectional shape of the shaft 10 is not limited to the above embodiment. For example, the other end of the shaft 10 protruding from the back surface of the base plate 9 may be a partial circle that can contact the switch 11 over a certain angle.
Alternatively, when the window glass is in the closed position, the switch is turned on to release the stopper device, and when the window glass is in another position, the switch is turned off and the stopper device is activated.

It is a front view of the window regulator which shows embodiment of this invention. It is a principal part disassembled perspective view of the window regulator which shows embodiment of this invention. It is the principal part perspective view seen from the back surface of the window regulator which shows embodiment of this invention. It is a rear view of a switch and a shaft when the switch is ON. It is a rear view of a switch and a shaft when the switch is OFF.
