Detailed Description
Hereinafter, a window glass raising/lowering device according to an embodiment of the present invention will be described with reference to the drawings. The embodiments described below are merely examples, and the window glass lifting device of the present invention is not limited to the embodiments described below.
As shown in fig. 1 and 2, a window glass lifting device 1 of the present embodiment includes: a drive section 2; a moving member 3 to which a window glass W is attached; a cable 4 that is wound and unwound by the driving unit 2 to move the moving member 3; a pulley 5 provided on the side of the ascending direction of the window glass W and converting the direction of the cable 4; and a pulley bracket 6 having a support portion 61 for supporting the pulley 5. In the present embodiment, the window glass up-down device 1 further includes a guide member 7 that guides the moving member 3.
The window glass lifting device 1 is attached to a predetermined attachment object and lifts and lowers a window glass W. The window regulator 1 of the present embodiment is a window regulator to be mounted on a door panel P (see fig. 2) or the like mounted on a vehicle body, for example. The window regulator 1 may be mounted to an object other than the door panel P of the vehicle body. In the present specification, regarding each member of the window glass up-down device 1, the direction in which the window glass W is raised in the direction in which the window glass W is raised when the window glass up-down device 1 is attached to the object is referred to as "up", "up" or "raising direction", and the direction in which the window glass W is lowered is referred to as "down", "down" or "lowering direction".
As shown in fig. 1 and 2, the window glass up-down device 1 of the present embodiment is provided with a drive unit 2 on the lower end side of the window glass up-down device 1, a pulley 5 on the upper end side of the window glass up-down device 1, and a guide member 7 along the up-down direction between the drive unit 2 and the pulley 5. However, the structure of the window glass lifting device 1 is not limited to the illustrated structure. The window regulator 1 may have another known structure such as a structure in which the drive unit is provided near the center of the guide member 7 in the longitudinal direction.
The drive unit 2 is a drive source for driving the cable 4. The driving unit 2 may be configured to electrically drive the cable 4, or may be configured to manually drive the cable 4. In the present embodiment, as shown in fig. 1, the driving unit 2 includes a motor 21 and a drum 22. The motor 21 is configured to be capable of rotating forward and backward and to rotate the drum 22 forward and backward. Thereby, the cable 4 connected to the drum 22 is wound around the drum 22 and paid out from the drum 22.
The cable 4 is operated by the driving unit 2 to move the moving member 3 connected to the cable 4 in the up-down direction. In the present embodiment, the wire 4 is connected to the reel 22 and the moving member 3 of the driving unit 2. In the present embodiment, as shown in fig. 1, the cable 4 has a first cable 41 and a second cable 42. One end (not shown) of each of the first wire 41 and the second wire 42 is connected to the driving unit 2 (the drum 22). The other ends of the first cable 41 and the second cable 42 are connected to the moving member 3.
In the present embodiment, the first cable 41 is a raising cable, extends in a raising direction from the driving unit 2 (the drum 22) toward the pulley 5, and is switched in direction by the pulley 5 to extend in a lowering direction toward the moving member 3. In the present embodiment, the second cable 42 is a lowering cable and extends in a downward direction from the moving member 3 toward the driving unit 2. In addition, a known control cable can be used as the cable 4. In the present embodiment, the cable 4 is configured by 2 cables, but may be configured by 1 cable.
The moving member 3 is moved up and down by the cable 4, and the window glass W connected to the moving member 3 is moved up and down. In the present embodiment, the moving member 3 is attached to the guide member 7, and moves in the longitudinal direction of the guide member 7 to move the window glass W up and down. As shown in fig. 2, the moving member 3 has a window glass connecting portion 31, and the window glass W is directly or indirectly attached to the window glass connecting portion 31. When the window glass W is attached to the moving member 3, for example, the lower end of the window glass W is connected to the moving member 3 by moving downward by the upper end portion of the window glass lifting device 1 attached to the door panel P, that is, laterally of the pulley 5 and the pulley bracket 6.
In the present embodiment, as shown in fig. 1, the moving member 3 has a first connecting portion 32a to which an end portion of the first cable 41 is connected and a second connecting portion 32b to which an end portion of the second cable 42 is connected. The shape or structure of the moving member 3 is not limited to the illustrated shape or structure.
The guide member 7 guides the moving member 3 so as to move the moving member 3 along a predetermined movement path. The guide member 7 has a predetermined length in the vertical direction so as to move the moving member 3 and the window glass W by a predetermined moving length. In the present embodiment, as shown in fig. 1 and 2, a pulley 5 is attached to one end (upper end) side of a guide member 7 via a pulley bracket 6, and a driving unit 2 is connected to the other end (lower end) side of the guide member 7.
In the present embodiment, the guide member 7 is formed in an elongated plate shape extending along the moving path of the moving member 3. In the present embodiment, the guide member 7 is curved in an arcuate shape along the longitudinal direction of the guide member 7 so as to follow the curvature of the door panel P, similarly to the window glass W. The guide member 7 is not particularly limited in shape as long as it can guide the moving member 3 along a predetermined moving path.
The pulley 5 is a member that rotates about a predetermined axis X (see fig. 3) for converting the extending direction of the cable 4. In the present embodiment, the pulley 5 is rotatably supported by the pulley bracket 6. Specifically, as shown in fig. 3, the pulley 5 is rotatably attached to the support portion 61 of the pulley bracket 6 via the shaft member AX. The structure of the shaft member AX is not particularly limited as long as it can axially support the pulley 5 so as to be rotatable with respect to the pulley holder 6. For example, in the present embodiment, the shaft member AX is formed of one member, but may be formed of a plurality of members.
As shown in fig. 3 and 4, the pulley 5 includes: one end surface 51 facing the support portion 61 of the pulley bracket 6, the other end surface 52 on the opposite side of the one end surface 51, and a cable guide groove 53 for guiding the cable 4. As shown in fig. 3 and 4, the cable guide groove 53 is formed so as to be recessed radially inward from the outer periphery of the pulley 5. In the present specification, the radially inner portion of the cable guide groove 53 is referred to as a bottom B of the cable guide groove 53 (see fig. 4), and the cable 4 is guided along the bottom B.
The pulley bracket 6 is a member that supports the pulley 5. As described above, the pulley bracket 6 has the support portion 61 that supports the pulley 5. In the present embodiment, as shown in fig. 3, 5, and 6, the pulley bracket 6 further includes a guide fixing portion 62 fixed to the guide 7, and an attachment portion 63 attached to an attachment object such as the door panel P. In the present embodiment, a support portion 61 is provided on the upper end side of the sheave bracket 6, an attachment portion 63 is provided on the lower end side, and a guide member fixing portion 62 is provided between the support portion 61 and the attachment portion 63. The guide member fixing portion 62 is a portion fixed to the guide member 7 by a known fixing means such as welding or bolts. The mounting portion 63 is mounted to a mounting target portion such as the door panel P using a fastening member BL such as a bolt.
In the present embodiment, the pulley bracket 6 has a width similar to that of the guide member 7, and is formed of an elongated bent plate-like member extending in the vertical direction. In the present embodiment, the support portion 61 and the guide member fixing portion 62 extend substantially on the same plane, and the attachment portion 63 extends substantially parallel to the support portion 61 and the guide member fixing portion 62, apart from the guide member 7 in the thickness direction of the guide member 7.
The shape and structure of the pulley bracket 6 are not limited to those shown in the drawings. For example, the pulley bracket 6 may be configured to be attached to the door panel P at the support portion 61 without the attachment portion 63. For example, the pulley bracket 6 may be attached to the door panel P by projecting a shaft member (a member that axially supports the pulley 5 in the same manner as the shaft member AX) from a surface 61c of the support portion 61 on the opposite side to an opposing surface 61b described later, and engaging the shaft member with an insertion hole of the door panel P. The material of the pulley bracket 6 is not particularly limited, and is made of metal, resin, or the like having predetermined rigidity.
As shown in fig. 3 and 4, the support portion 61 of the pulley bracket 6 includes: a shaft support portion 61a that supports the pulley 5, and an opposing surface 61b that faces the one end surface 51 side of the pulley 5. The support portion 61 is a portion that supports the pulley 5. In the present embodiment, as shown in fig. 1 and 3, the end edge Ea on the ascending direction side of the facing surface 61b is located at a position facing the one end surface 51 of the pulley 5 in the axis X direction of the pulley 5. In the present embodiment, as shown in fig. 1 and 5, when the pulley 5 is viewed in the direction of the axis X, the end edge Ea of the support portion 61 is formed so as to curve along the outer peripheral portion of the one end surface 51 of the pulley 5. Thus, the support portion 61 does not protrude substantially upward from the upper end of the pulley 5, and the window glass up-down device 1 is made compact in the vertical direction.
The shaft support portion 61a is a portion that supports the pulley 5. In the present embodiment, as shown in fig. 3 and 4, the shaft support portion 61a has a through hole H through which the shaft member AX is inserted, and the pulley 5 is rotatably supported by the pulley bracket 6 via the shaft member AX inserted through the through hole H. In the present embodiment, the pulley 5 is attached to the pulley bracket 6 by attaching the shaft member AX to the pulley bracket 6, but a shaft portion having the same function as the shaft member AX may be provided in advance in the shaft support portion 61a of the pulley bracket 6.
The pulley 5 rotates in a state where one end surface 51 of the pulley 5 faces the facing surface 61b of the support portion 61. In the present embodiment, at least a part of one end surface 51 of the pulley 5 abuts against the facing surface 61b of the support portion 61, and slides in the rotation direction of the pulley 5. The facing surface 61b is the entire surface of the support portion 61 facing the one end surface 51 of the pulley 5 in the direction of the axis X, and is independent of whether or not it is in contact with the pulley 5.
In the present embodiment, as shown in fig. 3 and 4, the facing surface 61b is configured such that the end E on the ascending direction side extends in a direction including the axis X direction of the pulley as a directional component so that the distance between the one end surface 51 on the outer peripheral portion of the pulley 5 on the ascending direction side and the facing surface 61b is larger than the distance between the one end surface 51 on the shaft support portion 61a side and the facing surface 61 b.
Here, the "end E on the ascending direction side" of the facing surface 61b refers to a predetermined region from the end edge Ea on the ascending direction side in the facing surface 61 b. In the present embodiment, as shown in fig. 5, the "end E on the ascending direction side" of the facing surface 61b is a predetermined region from the curved end edge Ea extending along the outer peripheral portion of the pulley 5. In the present embodiment, as shown in fig. 3 and 4, the sheave bracket 6 includes a flat portion 611 extending substantially parallel to the one end surface 51 of the sheave 5, and a separating portion 612 located on the side of the flat portion 611 in the upward direction and extending in the direction of separating from the one end surface 51 of the sheave 5, and an end E is formed at the separating portion 612.
In addition, the "interval between the one end surface 51 on the shaft support portion 61a side and the facing surface 61 b" means the minimum interval between the one end surface 51 and the facing surface 61b at a position closer to the shaft support portion 61a than the end portion E of the facing surface 61 b. For example, when the one end surface 51 and the facing surface 61b slide on the shaft support portion 61a side with respect to the end portion E, the distance is defined as the distance between the sliding portions. Therefore, the "interval between the one end surface 51 on the shaft supporting portion 61a side and the facing surface 61 b" is, for example, an interval that is the smallest interval between the one end surface 51 and the facing surface 61b at all times even if the interval between the one end surface 51 and the facing surface 61b is locally increased due to a portion where a lightening hole is provided in the pulley 5, a portion where the thickness of the pulley 5 is locally reduced in the vicinity of the shaft supporting portion 61a, or the like.
The phrase "the end E on the side of the ascending direction extends in a direction including the axis X direction of the pulley 5 as a directional component" means that the end E of the facing surface 61b does not extend along a plane perpendicular to the axis X (a direction parallel to the one end surface 51 of the pulley 5), but extends away from the one plane perpendicular to the axis X. In the present embodiment, as shown in fig. 3 and 4, the pulley bracket 6 is bent or bent at the end E of the facing surface 61b so as to extend obliquely away from the one end surface 51 of the pulley 5 at a position facing the end E. In the present embodiment, as shown in fig. 4, the facing surface 61b of the end portion E has an upward surface in which the perpendicular line V includes the axis X direction of the pulley 5 as a directional component. In the present embodiment, the facing surface 61b is a curved surface at the end portion E, but may be an inclined flat surface. The facing surface 61b may be bent substantially perpendicularly so as to extend substantially parallel to the axis X at the end E on the upward direction side of the sheave bracket 6.
As described above, the facing surface 61b of the pulley bracket 6 is formed such that the end E on the side of the upward direction extends in the direction including the axis X direction of the pulley 5 as a directional component so that the interval between the one end surface 51 and the facing surface 61b is larger than the interval between the one end surface 51 on the side of the shaft support portion 61a and the facing surface 61 b. Therefore, for example, as shown in fig. 4, even when a burr BR is generated at the end edge Ea of the end portion E of the pulley bracket 6 during forming or machining, the contact between the one end surface 51 of the pulley 5 and the burr BR can be suppressed. This can suppress breakage of the pulley 5 due to contact between the burr BR of the pulley bracket 6 and the one end surface 51 of the pulley 5. Further, when the window glass W is attached to the window glass lifting device 1 attached to the object to be attached such as the door panel P, when the lower end of the window glass W passes through the upper end of the window glass lifting device 1, the lower end of the window glass W can be prevented from colliding with the pulley 5 or the pulley bracket 6 and causing the pulley 5 to contact the burr BR. Therefore, according to the window glass lifting device 1 of the present embodiment, breakage of the pulley 5 due to the burr BR can be suppressed. Further, if the length of the pulley bracket 6 is increased in order to separate the front end portion of the pulley bracket 6 from the pulley 5 in order to prevent the pulley 5 from contacting the burr at the front end portion of the pulley bracket 6, the corner of the end face of the front end portion of the pulley bracket 6 and the facing surface 61b may contact the window glass W, thereby damaging the window glass W. However, since the facing surface of the front end portion of the pulley bracket 6 faces upward by separating the facing surface of the pulley bracket 6 from the outer peripheral portion of the pulley as described above, the window glass W is less likely to be damaged even if the front end portion of the pulley bracket 6 contacts the window glass W.
In the present embodiment, as shown in fig. 4, the end E of the sheave bracket 6 on the side in the upward direction has a curved portion that separates from the sheave 5. By providing the end portion E with a curved portion, the angle between the perpendicular line V of the facing surface 61b at the portion where the end edge Ea of the burr BR is formed and the line L parallel to the one end surface 51 of the pulley 5 becomes smaller than in the case where the end portion E is not curved (for example, in the case where the end edge Ea is positioned at the same position, but the end portion E is an inclined plane). Therefore, even when the burr BR is generated at the end edge Ea of the pulley bracket 6, the extending direction of the burr BR is not easily directed toward the one end surface 51 of the pulley 5. Therefore, breakage of the pulley 5 can be further suppressed.
In the present embodiment, as shown in fig. 3 and 4, the pulley bracket 6 has the flat portion 611 and the separated portion 612, and as shown in fig. 4, the separated portion 612 provided at the end portion E is formed in a region on the ascending direction side of the bottom portion B of the cable guide groove 53 of the pulley 5. In this case, even if a force (see arrow AR in fig. 4) is applied from the cable 4 to the pulley 5 so that the one end face 51 is pressed toward the facing surface 61b when the cable 4 is operated, the one end face 51 abuts on the flat portion 611, and the wobbling of the pulley 5 is suppressed. Therefore, by suppressing the wobbling of the pulley 5, the damage or breakage due to the contact between the pulley 5 and the burr BR can be further suppressed. Further, since the pulley bracket 6 has the flat portion 611 and the separation portion 612, abnormal noise generated by the pulley 5 and the burr BR can be suppressed.
