[Industrial applications]

 The present invention relates to an improvement of a vehicle window glass opening / closing mechanism.

[0002]

[Prior Art]

 In recent years, a rounded design has been adopted as a vehicle shape of a vehicle, particularly a passenger car, mainly in order to reduce air resistance during traveling. Along with this, the opening and closing mechanism has been improved so that the door window glass is curved to match the curved surface of the door and the window glass moves up and down along the curved surface of the door.

Further, in order to prevent noise during traveling from entering the passenger compartment, the cross-sectional shape of the glass run is improved in response to the curved surface of the window glass, and the close contact with the window glass is strengthened. Is designed to be.

[0004]

[Problems to be solved by the device]

 However, in such an opening / closing mechanism, a loud pop-up noise may occur when closing the window glass. For this reason, an attempt was made to attach a foam of rubber or synthetic resin to the contact surface of the window glass of the glass run, but even if the effect was recognized in the initial stage, especially when the opening / closing mechanism is an electric window Since the pushing force of the glass is extremely large, the foam or the glass run itself may be deformed over time and the effect may be reduced.

The above-mentioned problem is that when the opening / closing mechanism is of an electric type, the circuit opens when the rising window glass comes into contact with the glass run and overcurrent flows to the motor. This is because it is designed to stop the rotation of the handle after feeling that the load on the handle has suddenly increased in the case of the manual type. Therefore, it is inevitable to make a loud noise when the edge of the window glass suddenly hits the glass run.

An object of the present invention is to provide a vehicle window glass opening / closing mechanism in which the above-mentioned conventional drawbacks are eliminated by a simple structure.

[0007]

[Means for Solving the Problems]

 The vehicle window glass opening / closing mechanism of the present invention is characterized in that an upper limit stopper having a shock absorbing function is provided at the operating end position corresponding to the window glass closing position of the manual or electric type opening / closing mechanism. Therefore, the problem can be solved.

【Example】

 Embodiments of the present invention will be described in detail with reference to the drawings. 1 is a wire drum type opening / closing mechanism, and FIG. 2 is an explanatory view of the relevant parts showing an X-arm type opening / closing mechanism.

In the wire-drum type opening / closing mechanism of FIG. 1, a glass lift base that is an operation unit that transmits the rotation of the wire drum 5 supported by a door body (not shown) to the wire 3 and supports the lower end of the window glass 6. 2 is raised or lowered along the guide rail 1. The wire 3 is locked to the glass lift base 2, and the upper and lower pulleys 30 and 31 that guide the wire 3 are rotatably supported by the upper and lower brackets 32 and 33 fixed to the door body, respectively. Is integrally fixed to the upper and lower brackets 32 and 33. The wire drum 5 is rotationally driven by a motor (not shown) or manually.

In such a manual or electric vehicle window glass opening / closing mechanism, a lower end on which the glass lift base 2 abuts has been conventionally located at the operation end position of the guide rail 1 corresponding to the lower limit position of the window glass 6. Although the stopper 9 is provided, no stopper is provided at the portion corresponding to the window glass closing position at the rising limit. The feature of this embodiment is that the upper limit stopper 7 having a shock absorbing function is provided at the operating end position corresponding to the closed position of the window glass 6.

As shown in FIG. 3, the upper limit stopper 7 is slidably fitted to a stopper main body 21 fixed to an upper bracket 32 via a screw 34 and a protrusion protruding downward from the main body 21. It has a combined cylindrical cover 22 and a compression coil spring 23 which is housed in the cover 22 and biases the cover 22 downward with respect to the stopper body 21. The stopper body 21 may be fixed to the guide rail 1.

When the glass lift base 2 continues to move upward by being pulled by the wire 3, the upper edge of the glass lift base 2 directly or on the contact portion 8 (FIG. 1) provided on the upper edge of the upper limit stopper 7 The cover 22 is slightly raised while coming into contact with the cover 22 and compressing the spring 23 therein. By the buffer function at this time, the rising speed of the glass lift base 2 and the window glass 6 is moderated, and at the same time, an overcurrent flows to the motor of the wire drum 5 to open the circuit and stop the motor, or to handle it with the feel of that time. Therefore, the edge of the window glass 6 is smoothly stored in the glass run (not shown). In this way, the shock when closing the window glass 6 is absorbed, and the generation of the thrusting sound is reduced.

The glass run is made of rubber or soft synthetic resin having a substantially concave section, and when the window glass is closed, holds the other edge surfaces except the lower edge of the window glass in the recess. In addition, it prevents rainwater and dust from entering the passenger compartment and prevents the window glass from vibrating.

As shown in FIG. 3, the stopper body 21 is provided with an ear portion 24 projecting therefrom, and an elongated hole 25 parallel to the guide rail 1 is formed therein, and the aforementioned screw 34 is inserted into the elongated hole 25. It is screwed into the screw hole of the bracket 32. Finely adjust the position of the upper limit stopper 7 by loosening the screw 34, sliding the sweeper main body 21 up and down along the guide rail 1, tightening the screw 34 again, and fixing the stopper main body 21 to the bracket 32. You can By allowing the mounting position of the upper limit stopper 7 to be finely adjusted as described above, the position of the upper limit stopper 7 can be set so that an optimum shock absorbing function can be obtained.

In the X-arm type opening / closing mechanism shown in FIG. 2, the motor 16 is supported by the opening / closing mechanism body 10 fixed to the door body, and the arm 14 is pivotally attached to the body 10 via the shaft 11. The gear 12 is integrally fixed to one end of the arm 14. A roller is attached to the other end of the arm 14 and is fitted into the guide groove of the glass support frame 13 supporting the window glass 6 so as to be rotatable. A pinion (not shown) driven by the motor 16 is rotatably supported by the opening / closing mechanism main body 10, and the pinion meshes with the gear 12.

When the motor 16 is operated, its rotation is transmitted to the drive pinion through the reduction gear, and the rotation of the drive pinion moves the gear 12, and as a result, the arm 14 pivots about the axis 11. Therefore, the roller attached to the arm 14 rolls in the guide groove of the glass supporting frame 13, whereby the glass supporting frame 13 moves up and down together with the window glass 6.

Also in this opening / closing mechanism, conventionally, no stopper for restricting the rising limit of the window glass 9 is attached to the gear 12 which is the operating portion, and the teeth of the gear 12 are provided beyond the rising limit of the window glass 9. It was being done. In the opening / closing mechanism of this embodiment, the upper limit stopper 17 is provided at the operating end position of the gear 12 corresponding to the closed position of the window glass 6. The upper limit stopper 17 is configured in exactly the same way as the upper limit stopper 7 shown in FIG. 3, and contacts the upper edge of the main body 10 or the contact portion 18 provided at the upper edge of the main body 10 when the window glass 6 rises, Similar to the wire drum type opening / closing mechanism, the window glass 6 stops rising, and its edge is smoothly stored inside the glass run. Therefore, the generation of thrust noise is reduced.

In the embodiment shown in FIG. 3, the spring 23 is configured to obtain a shock absorbing function, but a shock absorbing means using rubber or hydraulic pressure may be used.

[Effect of the device]

 According to the vehicle window glass opening / closing mechanism of the present invention, when the actuating part including the glass lift base or the gear comes into contact with the upper limit stopper directly or through the contact part, the rising speed is moderated and at the same time the overcurrent is generated. As the motor runs and the motor stops, the edges of the glazing are smoothly stored inside the glass run, thus reducing the generation of unpleasant popping noises.

Similarly, even in the manual window glass opening / closing mechanism, the rotation of the handle is slowed down by hand, so that the edge of the window glass 6 is smoothly stored inside the glass run. Therefore, the generation of thrust noise is reduced.

As yet another effect, in the window glass opening / closing mechanism of the present invention, the edge of the window glass is smoothly accommodated inside the glass run, so that the life of the glass run is greatly extended and a heavy load is applied. Since there is no deformation, no wind noise is generated and the quietness inside the vehicle can be maintained.
