Description

  The present invention relates to a window regulator, and more particularly to a window regulator attached to a vehicle door.

JP 2001-199236 A

  Patent Document 1 discloses a cable-type window regulator 100 provided on a vehicle door as shown in FIG. The window regulator 100 includes a guide rail 101 arranged in the vertical direction, a carrier plate 102 that is slidably provided on the guide rail and supports the window glass W, and rollers provided at the upper and lower ends of the guide rail 101. Or a direction changing member 103 such as a pulley, a loop of the inner cable 104 wound around the upper and lower direction changing members 103, and motor-driven cable driving devices 105 and 106 for reciprocating and circulating the loop of the inner cable 104. .

  Such a window regulator 100 is accommodated in the interior space of the door consisting of an outer panel and an inner panel 107, and the guide rail 101 and the cable driving devices 105 and 106 are fixed to the inner panel 107 with screws or the like. The inner panel 107 is made of a synthetic resin reinforced with a metal plate.

  In Patent Document 1, the guide rail 101 and the drum 105 of the cable drive device are attached to the inner surface (the side facing the outer panel) of the inner panel, and the motor is equipped with a motor and a speed reducer that drives the drum to the outer surface (inner side). An auxiliary machine assembly structure for a vehicle door is disclosed in which a part 106 is attached and the output shaft of the speed reducer passes through the inner panel 107. Other auxiliary machines such as the door speaker 108 are also attached to the inner panel 106.

  On the other hand, in order to make it easy to attach the window regulator, etc. to the inner panel, the window regulator, inner handle, lock, speaker, etc. are assembled in advance on the panel called the module panel, and the large opening provided in the inner panel of the door There is a method of mounting so that the module panel is closed. In this method, door auxiliary machines are attached in advance and modularized (unitized), so that the door assembly process is simplified.

  There is also known a so-called railless window regulator in which a guide rail is not used and a direction changing member such as a pulley and a cable driving device are attached to an inner panel. In this case, the carrier plate is not guided by the guide rail, the window glass is guided by the door sash or the glass run channel, and the carrier plate is indirectly guided by the glass run channel through the window glass.

  Since the conventional window regulator attached to the module panel has an element supporting the tension of the inner cable attached to the module panel, it is necessary to increase the rigidity of the module panel. Based on the demand for lighter vehicles, it is desirable to reduce the thickness and thickness of the module panel. However, as the thickness of the panel is increased, the rigidity and strength of the module panel will decrease, and the load when the window glass is raised and lowered may be repeatedly received. Due to the cable tension before assembly to the door, the deformation and durability of the module panel becomes a problem.

  It is an object of the present invention to provide a window regulator capable of performing a predetermined function by making use of the rigidity of an inner panel or reinforcement to prevent deformation and a decrease in durability even if the module panel is thinned. It is an issue.

  The window regulator according to the present invention (Claim 1) is a window regulator that is attached to a door of a vehicle, and includes a direction changing member that is respectively attached to upper and lower sides of a door inner panel or a reinforcement by an attaching screw, and the direction change thereof. A loop of an inner cable that is hung around a member, a carrier plate that is attached to the loop of the inner cable and supports a window glass, and a motor-driven cable driving device for reciprocating circulation of the loop of the inner cable; A module panel that is attached to the inner panel or the reinforcement together with the direction changing member by the mounting screw is provided.

  In such a window regulator, the upper and lower direction change members are each composed of a set of four pieces arranged in front and rear of the door, and the loop of the inner cable is routed in an eight-letter shape. It is preferable that a carrier plate is attached to each of the portions extending in the vertical direction. Further, it is preferable that at least one of the direction changing members is a pulley that is rotatably provided around a mounting screw. Further, it is preferable that the cable driving device is attached in the vicinity of the speaker hole of the module panel.

  In the window regulator of the present invention (Claim 1), the module panel to which the door accessory is attached is attached to the inner panel or the reinforcement together with the direction changing member. For this reason, since various accessory devices can be attached to the inner panel together, the attaching operation is simple, and a large force is not applied to the module panel, so that it can be made thin. That is, the direction change member that supports the reaction force of the inner cable is attached to the module panel, but is also attached to the inner panel or the reinforcement at the same time, so the reaction force of the tension of the inner cable is a highly rigid inner panel. Or supported by reinforcement. Therefore, the module plate can be made thin.

  In addition, the reaction force which a direction change member should support with the direction change of an inner cable is so large that the angle of direction change is large. For example, when the direction change angle is 180 degrees, that is, when the direction is reversed, a supporting force that is twice the tension is required. On the other hand, the force for supporting the cable driving device is maximum, that is, when the tension on the sending side is zero, the tension on the winding-side inner cable is sufficient. Accordingly, the reaction force of the inner cable to be supported by the module panel may be small, and the required plate thickness and strength may be reduced accordingly.

  The upper and lower direction change members are each composed of a set of four pieces arranged on the front and rear sides of the door, the inner cable loops are arranged in an eight-letter shape, and the carrier plates are respectively provided in the portions extending in the vertical direction of the inner cables. In the case of the attached window regulator (Claim 2), the window glass can be stably supported at the two front and rear positions.

  Further, when at least one of the direction changing members is a pulley that is rotatably provided around a mounting screw (Claim 3), the movement of the inner cable is smooth. Further, when the cable driving device is attached in the vicinity of the speaker hole of the module panel (Claim 4), the cable driving device can be easily attached to the module panel using the speaker hole.

  Next, an embodiment of the window regulator of the present invention will be described with reference to the drawings. 1 is a schematic side view showing an embodiment of a door provided with the window regulator of the present invention, FIG. 2 is an enlarged sectional view taken along line II-II in FIG. 1, and FIG. 3 is an enlarged sectional view taken along line III-III in FIG. FIG. 4 is a perspective view showing an embodiment of a cable driving device according to the present invention, and FIGS. 5a and 5b are a front view and a side view of the cable driving device of FIG. 4, respectively.

  FIG. 1 shows a state in which a door of a vehicle, particularly a front door 10 of an automobile, is viewed from the inside of the vehicle. The door 10 includes an outer panel 11 provided on the outer surface, an inner panel 12 provided on the inner side of the vehicle, and a sash 13 provided on the upper portion thereof. A glass run channel for slidably guiding the window glass W up and down is provided at the mouth portion of the sash 13 and the front portion of the door.

  The outer panel 11 protrudes outward as shown in FIG. 2, and the inner panel 12 protrudes inward (inside the room). Accordingly, when the periphery of the outer panel 11 and the inner panel 12 is overlapped and fixed by welding or the like, a cavity 15 is formed inside. The cavity 15 is equipped with equipment such as a window regulator 16. The outer panel 11 and the inner panel 12 are thin steel plate press-formed products. The inner panel 12 may be a synthetic resin panel reinforced with a metal plate.

  Returning to FIG. 1, the inner panel 12 has a large opening 17 in the center, and the opening 17 is closed by a module panel 18. The module panel 18 is a thin plate made of synthetic resin or the like, and in this embodiment, a speaker hole 19 for mounting the speaker is formed in the lower part of the front side (left side in FIG. 1). The module panel 18 can be manufactured by hot press molding or injection molding a synthetic resin sheet.

  The window regulator 16 is attached to the periphery of the opening 17 at the upper and lower portions of the inner panel 12, and includes an upper front pulley 21, an upper rear pulley 22, a lower front pulley 23, and a lower rear pulley 24 as direction change members. Each pulley and a cable driving device 25 attached to the module panel 18 are provided. The four pulleys 21 to 24 have inner cables 26, 27, 28 stretched in a horizontal 8-shaped loop shape, and carrier plates are respectively provided at portions extending in the longitudinal direction on the front side and the rear side. 29 and 30 are connected. No guide rail is used. The cable driving device 25 can also be attached to the inner panel 12 or the reinforcement 12a arranged in the vertical direction indicated by an imaginary line. Furthermore, when using a guide rail, it can also be attached to the guide rail.

  One end of the loop of the inner cables 26, 27, and 28 is locked to the drum of the cable driving device 25, extends obliquely rearward, is turned downward by the upper rear pulley 22, and the other end is engaged with the rear carrier plate 30. The first inner cable 26 to be stopped, one end is locked to the rear carrier plate 30, extends downward, is turned obliquely forward by the lower rear pulley 24, is turned by the upper front pulley 21, and extends downward. A second inner cable 27 whose other end is locked to the front carrier plate 29, and one end locked to the front carrier plate 29, extending downward, being turned by the lower front pulley 23, and obliquely rearward The other end is divided into a third inner cable 28 that is extended to the drum of the cable driving device 25 and that has the other end. However, it may be one continuous inner cable.

  The inner cables 26 to 28 are conventionally known ones used in cable type window regulators. That is, each of the inner cables 26 to 28 is known as an inner cable of a pull control cable in which metal strands are twisted together and a metal cable end is cast or fixed by caulking. In some cases, a synthetic resin coat may be provided on the outer periphery of the stranded wire of the metal strand. In this embodiment, an outer casing (conduit) is not used. However, an outer casing may be used. An outer casing is a well-known thing which consists of the armor layer which wound the metal wire of a square cross section helically, and the synthetic resin protective layer provided in the surface. In some cases, a synthetic resin liner is provided inside the armor layer.

  The carrier plates 29 and 30 are provided with a mounting step portion and a mounting hole for mounting to the lower end of the window glass W, and are provided with a locking portion for locking the cable ends of the two inner cables. It is made of a plate. There is also a case of a synthetic resin product in which metal parts are insert-molded. Since the window regulator 16 does not use a guide rail, a sliding portion that slides with the guide rail is not provided. In some cases, the front carrier plate 29 and the rear carrier plate 30 are integrated into a long plate in the front-rear direction.

  As shown in FIG. 2, the upper front pulley 21 is a well-known disk-shaped part having a guide groove 31 on the outer periphery and a mounting hole 32 in the center. In the window regulator 16, the support shaft of the pulley is provided. The screw 33 is also attached to the reinforcement 34 arranged in a lateral direction so as to be rotatable. The lateral reinforcement 34 is fixed to the vicinity of the inner edge of the opening 17 of the inner panel 12 by welding or the like, similar to the vertical reinforcement 12a described above, and is a reinforcing part integrated with the inner panel 12. It also serves to protect passengers against collisions from the side of the vehicle. In the window regulator 16, the module panel 18 is also attached together with the front upper pulley 21 using the screw 33. Reference numeral 35 denotes a cylindrical spacer, and reference numeral 36 denotes a nut. The spacer 35 can be fixed to the module panel 18 or can be fixed to the reinforcement 34 or the inner panel 12.

  As shown in FIG. 3, the lower front pulley 23 is the same component as the upper front pulley 21, and is rotatably attached to the inner panel 12 by screws 33. Similarly to the upper front pulley 21, the module panel 18 is attached together with the front lower pulley 22 using the screw 33. The spacer 35 and the nut 36 are the same as in the case of the upper front pulley 21.

  The attachment state of the upper rear pulley 22 to the inner panel 12 is substantially the same as the attachment state of the upper front pulley 21, and the attachment state of the lower rear pulley 24 is substantially the same as the attachment state of the lower front pulley 23. is there. In addition, as a direction change member, it can replace with a pulley and can also employ | adopt the well-known slide guide provided with the circular arc-shaped guide groove which guides an inner cable slidably.

  As shown in FIG. 4, the cable drive device 25 rotationally drives the housing 40, a drive shaft 41 rotatably provided in the housing 40, a drum 42 attached to the drive shaft 41, and the drive shaft 41. It consists of a motor M and a reducer G. The housing 40 has three arms 44 extending in the radial direction, and includes a drum housing portion 45 for housing the drum 42 and a motor mounting portion 46 for mounting the motor M. Then, the cable drive device 25 is attached to the module panel 18 by screwing the arm 44 to the module panel 18. The same applies to the case where the cable driving device 25 is attached to the inner panel 12 or the longitudinal reinforcement 12a. In this embodiment, since an outer casing is not used, the housing 40 is not provided with an outer mounting portion. As shown in FIG. 5 a, the two inner cables 26, 28 are routed with respect to the housing 40 so as to extend substantially opposite to each other.

  The drum 42 has a locking hole for locking the cable ends 26a, 28a fixed to the ends of the first inner cable 26 and the third inner cable 28, and a guide for winding the vicinity of the end of the inner cable in opposite directions. This is a known one having a groove and a central hole into which the drive shaft 41 is fitted.

  The housing 40 and the drum 42 are usually made of synthetic resin having high strength, but other materials may be used. The housing 40 is attached to the module panel 18 with three screws as shown in FIG. 5b. The housing 40 can be separated into a motor housing and a drum case, and can be attached to both sides of the module panel 18, the inner panel 12, or the longitudinal reinforcement 12 a. As the speed reducer G, for example, a worm speed reducer composed of a worm fixed to the output shaft of the motor M and a worm gear connected to the drive shaft 41 is used. A reduction gear can be interposed between the output shaft and the worm. A rubber damper may be interposed between the worm gear and the drive shaft.

  The cable driving device 25 is preferably provided with an extension mechanism for the inner cables 26 and 28. As a result, the entire loop of the inner cables 26, 27, 28 can be loosened during assembly, and a predetermined tension can be applied after assembly. As such an extension mechanism, for example, the drum 42 is divided into two by a plane perpendicular to the axis and engaged with each other by ratchet teeth rows, and elastically pressed against each other by a wave washer or the like, or a housing For example, one that elastically biases the inner cable laterally at a position protruding from 40.

  As the extension mechanism, a mechanism that shifts the attachment position of the pulleys 21 to 24 to the inner panel 12 in the direction of extending the wiring length can also be adopted. In addition, a spring that urges the cable end in the direction of extending the cable routing length by being interposed between the locking portions of the carrier plates 29 and 30 and the cable end may be employed.

  In the window regulator 16 configured as described above, first, the pulleys 21 to 24 are attached to the reinforcement 34 and the inner panel 12. Then, the first to third inner cables 26 to 28 are hung around the pulleys 21 to 24 together with the carrier plates 29 and 30 and the cable driving device 25, the module panel 18 is fitted into the screw 33, and the nut 36 is tightened. Finally, the window regulator 16 is assembled by attaching the cable driving device 25 to the module panel 18 or the inner panel 12 or the vertical reinforcement 12a. After the assembly, the inner cable extending mechanism described above removes the slack of the entire inner cable loop and applies an appropriate tension to the inner cable.

  When attaching the cable driving device 25 to the module panel 18 or the longitudinal reinforcement 12a, it is preferable to insert the hand from the speaker hole 19 in FIG. 1 to support the cable driving device 25. When the cable driving device 25 is separated into the motor housing and the drum case, only the drum case is connected to the loop of the inner cables 26 to 28, and the motor housing is connected to the module panel 18 or the inner panel 12 or vertically. You may make it attach from the front side of this reinforcement 12a.

  However, in addition to the above, other assembling methods such as attaching the front lower pulley 23 or the rear lower pulley 25 last may be employed. In that case, a notch is provided in a portion corresponding to the pulleys 23 and 25 of the module panel 18. You may provide the cover which covers the notch separately.

  As shown in FIG. 1, in the window regulator 16 configured as described above, when the motor M is rotated in one direction and the drum is rotated, for example, counterclockwise, the third inner cable 28 is wound around the drum. The first inner cable 26 is sent out from the drum. Thereby, the loop of the inner cables 26 to 28 circulates in the direction of arrow D, the front and rear carrier plates 29 and 30 are lowered, the window glass W is lowered, and the window is opened. When the motor M rotates in the reverse direction, the drum rotates clockwise, the loop of the inner cables 26 to 28 circulates in the direction of the arrow U, the window glass W rises, and the window is closed.

  The window regulator 16 can sufficiently support the strong reaction force of the inner cable because the pulleys 21 to 24 as the direction changing members are attached to the reinforcement or the inner panel 12. That is, in the case of the direction changing member, the inner cables 26 to 28 are changed in direction in the range of 90 to 180 degrees, particularly 120 ° to 150 °, so that the reaction force is large, but the pulleys 21 to 24 are rigid. Since they are attached to the high reinforcement 34 or the inner panel 12, their reaction force can be sufficiently supported.

  On the other hand, since the two inner cables 26 and 28 extend in a substantially linear direction in the cable driving device 25, it is not necessary to support a strong reaction force. A large force is not applied. Therefore, even if the module panel 18 that is thinner and lower in strength and rigidity than before is employed, the window glass W can be raised and lowered smoothly without bending or warping. When the cable driving device 25 is attached to the inner panel 12 or the longitudinal reinforcement 12a, of course, the reaction force of the tension of the inner cable is not applied to the module panel 18. However, when the cable drive device 25 is shipped and transported in a state where it is attached to the module panel 18, it can be assembled to the door as it is, and it is not necessary to transfer it to the vertically oriented module panel 12 a or the inner panel 12, which is preferable.

  The four pulleys 21 to 24 may be temporarily attached to the module panel 18 using the screws 33 and transferred to the inner panel 12 when assembled to the door. Accordingly, the module panel 18 can be shipped, transported and delivered in a state where the cable driving device 25 and the four pulleys 21 to 24 are set as a set. A structure in which the pulleys 21 to 24 are locked to the module panel 18 may be employed so that the positions of the pulleys 21 to 24 are not shifted when the screw 33 is removed. For example, when the spacer 35 of FIGS. 2 and 3 is configured integrally with the module panel 18, the pulleys 21 to 24 are not displaced even if the screw 33 is removed.

  In the embodiment of the window regulator, four pulleys are employed, but the cable driving device 25 may be disposed at the position of the front lower or rear lower pulley, and the pulleys may be omitted. In that case, an eight-shaped loop is formed by the three pulleys and the cable driving device 25. Further, if the central portion of the window glass W is supported by one carrier plate, two upper and lower pulleys are sufficient.

  In the above-described embodiment, the window regulator provided on the door of the automobile has been described. However, a window regulator for a lift gate (back door) and a window regulator for another vehicle such as a construction machine or a trailer house may be employed. it can.
