Description

Window regulator

The present invention relates to a window regulator that holds a window glass and moves it up and down, and more particularly, to a window regulator that is characterized by a structure for attaching a window glass and a carrier plate.

The vehicle window regulator moves the window glass by moving the carrier plate attached to the lower end of the window glass up and down with a lifting cable. For example, the window regulator of Patent Document 1 includes a glass holder that holds a lower end portion of a window glass, a carrier plate that is fastened to the glass holder, an ascending cable and a descending cable that are connected to the carrier plate at one end, And a driving device for moving the cable for lowering and the cable for lowering in the axial direction.

JP 2011-63158 A

In the window regulator as described above, when the raising cable and the carrier plate are connected below the fastening position between the glass holder for holding the window glass and the carrier plate, the pulling direction by the raising cable is changed. Since there is an angle difference in the moving direction with respect to the carrier plate, it is assumed that a large rotational moment is applied to the glass holder when the window glass is raised. Such a large rotational moment acting on the glass holder may cause a problem in the case of a so-called railless type window regulator that does not use a guide rail for guiding the carrier plate in the up-and-down direction of the window glass. In other words, since the railless type window regulator does not distribute the load due to the guide rail, the load due to the rotational moment concentrates on the fastening position between the glass holder and the carrier plate, and the glass holder may be deformed or broken. In particular, when the window glass reaches top dead center, the rotational moment applied to the fastening position between the glass holder and the carrier plate increases, and the glass holder may be deformed or broken.

An object of the present invention is to provide a window regulator capable of suppressing deformation or damage of the glass holder even when a large load is applied to the fastening position between the glass holder and the carrier plate.

The window regulator according to an aspect of the present invention includes a glass holder, a carrier plate, a lifting cable, a drive unit, and a support unit. The glass holder holds the lower end of the window glass. The carrier plate is fastened with the glass holder. One end of the ascending cable is connected to the carrier plate below the fastening position between the glass holder and the carrier plate. The drive unit is connected to the other end of the lifting cable and moves the lifting cable in the axial direction. The support portion is erected upward from the carrier plate so as to abut or approach the vehicle inner side surface of the glass holder. When the window glass reaches the upper end restraining position, the support portion abuts on the vehicle inner side surface of the glass holder. It is possible to receive a force applied to the holder. In such a window regulator, when the window glass reaches the upper end restraining position, the supporting part receives the force applied to the glass holder, so that the glass holder can be prevented from being deformed or damaged. Can be used in common.

The support part can be formed integrally with the carrier plate. For example, by manufacturing a carrier plate having a support portion by integral molding with a synthetic resin material, the support portion having the above-described function can be easily provided.

The window regulator can be a so-called railless type window regulator that does not use a guide rail for guiding the carrier plate in the vertical direction of the window glass. In addition, when a guide rail for guiding the carrier plate in the up-and-down direction of the window glass is provided, an upper direction changing portion that is provided at the upper end of the guide rail and changes the direction of the ascending cable can be further provided. In this case, parts can be shared between the railless type window regulator and the window regulator including the guide rail.

According to the present invention, when the window glass is raised, the glass holder is supported by the support portion provided on the carrier plate, whereby deformation and damage of the glass holder can be suppressed. Therefore, it is possible to use a conventional glass holder in a so-called railless type window regulator that does not have a guide rail for guiding the carrier plate in the up-and-down direction of the window glass, that is, regardless of the presence or absence of the guide rail. Therefore, it is possible to share the same glass holder.

The cable holding portion 73 is provided below the insertion hole 74 for fastening the carrier plate 32 and the glass holder 31. The window regulator is attached to the vehicle door so that the carrier plate moves in the interior space of the door structure. Here, when sufficient space for the movement of the carrier plate cannot be secured on the upper side of the door structure by securing the strength of the frame in the door structure, the upper end position of the movement of the carrier plate is the same as that in the normal door structure. It is below the upper end position. In such a case, in order to make the window opening of the vehicle fully closed by the window glass, the window glass is enlarged so that it can be fully closed even if the upper end position is on the lower side. Alternatively, it is necessary to connect the carrier plate and the window glass by separating the distance from the lower end position of the window glass to the connection position of the carrier plate and the rising side cable. However, when the window glass is enlarged, a glass holder and a carrier plate that can withstand the weight of the window glass are required. In order to connect the conventional glass holder to the carrier plate by separating the distance from the connecting position of the carrier plate and the rising side cable to the lower end of the window glass, the fastening position of the glass holder and the carrier plate is set to the carrier plate. Although it is necessary to move away from the connecting position with the ascending cable in the upward direction of the vehicle, if the connecting position and the fastening position are separated from each other, a moment around the connecting position is generated as will be described later, and a force is applied to the glass holder. There is a risk that the glass holder will be damaged. That is, according to the present invention, by providing a support portion that can reinforce the strength of the glass holder, the glass holder can be prevented from being damaged even if a conventional glass holder is used.

The support portion 72 is erected upward from the carrier plate so as to abut or approach the vehicle inner side surface of the glass holder, and when the window glass reaches the upper end restraining position where the window opening is fully closed, the glass holder It is an example of the structure which can contact | abut to the vehicle inner side surface, and can receive the force added to a glass holder. In this embodiment, the support portion 72 is erected upward from the main body portion 71 of the carrier plate 32, and is formed along the vehicle inner side surface (specifically, the inner piece 55) of the glass holder 31. The support portion 72 only needs to be able to receive a force applied to the glass holder 31 at the upper end restraining position. In the present embodiment, when the window glass 20 reaches the upper end restraining position by contacting the vehicle inner side surface 55a. The moment force received by the glass holder 31 is received. The connection means between the support portion 72 and the main body portion 71 of the carrier plate 32 is not limited. For example, the support portion 72 is integrally molded with a synthetic resin material, bonded with an adhesive, or fastened with a bolt or the like. Thus, the main body 71 may be continuously extended upward. Moreover, since the support part 72 should just contact | abut to the vehicle inner side surface of the glass holder 31 when the window glass 20 reaches | attains an upper end restraint position, you may contact | abut the vehicle inner side surface 55a of the inner piece 55. FIG. When the glass holder 31 receives a moment force, the support portion 72 and the glass holder 31 come close to each other, and the support portion 72 and the vehicle inner side surface 55a are arranged close to each other with a contactable gap. Also good. When the window glass 20 reaches the upper end restraining position, the support portion 72 can contact the vehicle inner side surface 55 a of the glass holder 31 and receive a force applied to the glass holder 31. As will be described later, when the carrier plate 32 is raised by the raising cable 33, a rotational moment is applied to the carrier plate 32 and the glass holder 31. In particular, when the window glass 20 reaches the upper end restraining position (when the upper end portion of the window glass 20 is fitted into a glass run provided on the upper portion of the window opening, the window glass 20 completely closes the window opening). The rotational moment load applied to the carrier plate 32 and the glass holder 31 is maximized. The rotational moment at this time acts in a direction in which the upper part of the carrier plate 32 and the glass holder 31 is rotated to the outside of the vehicle. Therefore, a moment acts on the glass holder 31 from the carrier plate 32 so that the window glass 20 rotates to the outside of the vehicle, but the rotational movement of the window glass 20 is limited by the first sash 13 and the second sash 14. Since the rotation of the glass holder 31 is also limited, the moment is concentrated on the glass holder 31. When the normal glass holder 31 is used, the glass holder 31 is destroyed by the moment concentrated on the glass holder 31, but the support portion 72 of the carrier plate 32 and the inner piece 55 are in contact with each other, When the carrier plate 32 rotates relative to the glass holder 31 and the support portion 72 and the inner piece 55 approach and come into contact with each other, the moment concentrated on the glass holder 31 can be relaxed by the support portion 72. .

The support portion 72 only needs to be able to support the vehicle inner side surface of the glass holder 31 so that the glass holder 31 can be prevented from being deformed or damaged by the rotational moment force applied near the fastening position between the glass holder 31 and the carrier plate 32. . In the illustrated example, the upper end position of the support portion 72 does not reach the upper end position of the inner piece 55 of the glass holder 31, but the upper end position of the support portion 72 reaches the upper end position of the inner piece 55 of the glass holder 31. May be. Further, the side surface shape of the support portion 72 facing the vehicle inner side surface 55a can be made the same shape as the vehicle inner side surface 55a of the glass holder 31. The support portion 72 has a surface that contacts the vehicle inner side surface 55a on the side surface of the inner piece 55, but may be a contact portion that can contact the vehicle inner side surface 55a and receive a force applied to the glass holder 31. For example, it may be a flat surface that is in surface contact with the vehicle inner side surface 55a or a protrusion that linearly contacts the vehicle inner side surface 55a. Moreover, the upper end edge of the support part 72 has the inclined surface 80 inclined facing the vehicle outer side. The inclined surface 80 guides the glass holder 31 to a predetermined position so that the work for assembling the glass holder 31 to the carrier plate 32 is facilitated. The inclined surface 80 can be omitted.

(2-3) Elevating Operation FIG. 5 is an explanatory diagram for explaining the operation when the window glass is raised by the window regulator. In FIG. 5, the left side is the inside of the vehicle, and the right side is the outside of the vehicle. The window regulator 30 moves the carrier plate 32 up and down by winding and unwinding the ascending cable 33 and the descending cable 34 by driving the drive motor 36. As a result, the window glass 20 held by the glass holder 31 can be raised and lowered.

The upper cable guide 37 around which the ascending cable 33 is hung is disposed on the indoor side of the movement locus of the window glass 20 so as not to hinder the movement of the window glass 20. Therefore, as shown in FIG. 5, the pulling direction B by the lifting cable 33 is inclined with respect to the rising direction A of the window glass 20 by the inner lead angle θ. Further, in the carrier plate 32, the vertical position at which the lifting cable 33 is coupled is defined as the coupling position with the lifting cable 33, and the vertical position of the bolt 61 and the nut 62 that fastens the glass holder 31 and the carrier plate 32. As a fastening position with the glass holder 31, the connection position with the raising cable 33 is located below the fastening position with the glass holder 31. The connection position of the carrier plate 32 with the lifting cable 33 is that the traction force T from the lifting cable 33 acts on the carrier plate 32 when the carrier plate 32 is lifted by the lifting cable 33. Is referred to as a lift point, and the upward position of the lift point is defined as a first position P1. The traction force T from the ascending cable 33 acting on the lift point acts on the carrier plate 32 in the traction direction B as shown in the figure. The fastening position of the glass holder 31 and the carrier plate 32 is a fastening position of the bolt 61 and the nut 62, and the upward position of this fastening position is the second position P2. As shown in FIG. 5, the first position P1 is offset downward by a distance α with respect to the second position P2.

The glass holder 31 holds the window glass 20 guided by the first sash 13 and the second sash 14, and is fastened to the carrier plate 32 by bolts 61 and nuts 62. Of the traction force T for raising the carrier plate 32 by the raising cable 33, the first component T1 acts in the ascending direction A of the window glass 20, and the second component T2 intersects the ascending direction A of the window glass 20. Act on. At this time, since the glass holder 31 fastened to the carrier plate 32 holds the window glass 20 guided by the first sash 13 and the second sash 14, the rotational movement of the window glass 20 in the ascending direction A is performed. It is regulated. Therefore, when the second component force T <b> 2 of the traction force T is applied to the carrier plate 32, a rotational moment M that rotates the carrier plate 32 around the fastening position between the glass holder 31 and the carrier plate 32 is generated. Such a rotational moment M increases as the distance α, which is an offset amount between the first position P1 and the second position P2, increases. Further, the larger the offset amount between the lift point and the fastening position in the vehicle inside / outside direction becomes, the larger it becomes. Moreover, it is estimated that the rotational moment M becomes the largest when the window glass 20 reaches the upper end restraining position.

The rotational moment M applied to the fastening position of the carrier plate 32 and the glass holder 31 acts in a direction in which the inner piece 55 of the glass holder 31 is inclined toward the inside of the vehicle, but the support portion 72 of the carrier plate 32 is the inner piece of the glass holder 31. 55, the elastic deformation of the glass holder 31 can be suppressed. Even when the support portion 72 of the carrier plate 32 is disposed with a predetermined gap from the inner piece 55 of the glass holder 31, after the inner piece 55 is elastically deformed and comes into contact with the support portion 72, the support portion 72. By receiving the rotational moment M, it is possible to suppress the inner piece 55 from being plastically deformed.

(3) Other Embodiments Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. For example, the window regulator of the present invention can be applied even when the above moment acts on the glass holder, and the breakage of the glass holder can be suppressed.

The present invention can be applied to a window regulator that raises and lowers the window glass by electric or manual operation.
