Description

The present invention relates to a window regulator for a vehicle door, and more particularly to a method for assembling a window regulator sub-assembly before being fixed to the vehicle door.

  In recent years, instead of a window regulator that fixes a metal guide rail in a vehicle door, a window regulator that fixes a resin panel formed integrally with the guide rail in the vehicle door has been adopted (for example, Patent Document 1). ). On the resin panel, a pulley is pre-supported by being positioned above and below the guide rail, and a wire coupled to a slider base that is supported by the guide rail so as to be movable up and down is wound around a winding drum via the pulley, and a window regulator As a result, the number of parts is reduced, the weight is reduced, and the strength is increased. When fixing the window regulator sub-assembly to the vehicle door, the resin panel is coupled to the door panel (inner panel) by the coupling bolt inserted into the shaft hole of the pulley, and the window glass is coupled to the slider base.

  In a window regulator equipped with such a resin panel, the pulley supported by the resin panel supports the pulley body rotatably on the pulley bracket in order to eliminate the friction with the resin panel and ensure the rotation. It is common to use a pulley assembly.

International Publication No. 2011/095414 Pamphlet

  When a window regulator subassembly is assembled in a window regulator having a resin panel, the pulley assembly must be supported on the resin panel in a state where a wire tension load is applied to the pulley body. For this reason, if the pulley assembly is randomly supported on the resin panel without considering the tension load on the pulley body, the wire wrapped around the pulley body may come off or the pulley assembly (pulley body) may be damaged. There is a risk of malfunction.

The present invention has been completed based on the awareness of the above problems. When the pulley assembly is supported on the resin panel, the wire wound around the pulley body comes off or the pulley assembly (pulley body) is damaged. It is an object of the present invention to provide a method for assembling a window regulator sub-assembly that can reliably prevent such a malfunction.

The method for assembling the window regulator sub-assembly according to the present invention includes the step of preparing a resin panel in which a guide rail extending in the vertical direction and a fitting recess located in at least one of the upper and lower sides of the guide rail are integrally formed; A step of holding a slider base to which a window glass is fixed to a guide rail so as to be movable up and down; and a wire fixed to the slider base is wound around a pulley body of a pulley assembly, and the pulley assembly is fitted into the fitting recess In the step of fitting the pulley assembly into the fitting recess, a first step of winding the wire around the pulley body of the pulley assembly for less than one revolution; fitting the axis of the pulley assembly into the fitting body. Tilted with respect to the axis of the recess, and the pulley body of the pulley assembly A second step of fitting a portion corresponding to the ear winding region into the fitting recess of the resin panel; and tilting the axis of the pulley assembly in a direction coinciding with the axis of the fitting recess; A third step of fitting a portion corresponding to the wire non-winding region of the pulley body into the fitting recess of the resin panel is performed in order (Claim 1).

  The resin panel extends in the center direction from the peripheral edge of the fitting recess when viewed in plan, and overlaps with the pulley body of the pulley assembly fitted in the fitting recess, and the pulley body is fitted into the fitting panel. A pulley retaining protrusion that prevents the recess from coming out is formed. In the second step, the axis of the pulley assembly is tilted with respect to the axis of the fitting recess, and the fitting below the pulley retaining protrusion is performed. It is preferable to insert a portion of the pulley assembly corresponding to the wire winding region of the pulley body into the recess.

  The resin panel is formed with a wire retaining protrusion that extends in the center direction from the peripheral edge of the fitting recess when viewed in plan, and in the second step, the axis of the pulley assembly is connected to the fitting recess. It is preferable to insert a portion of the pulley assembly corresponding to the wire winding region of the pulley body into the fitting recess below the wire pull-out projection.

  The resin panel is formed with an elastic protrusion extending in the center direction from the peripheral edge of the fitting recess when seen in a plan view. In the third step, the axis of the pulley assembly is connected to the fitting recess. It is preferable that a portion of the pulley assembly corresponding to the wire non-winding region of the pulley assembly is fitted into the fitting recess while being tilted in a direction matching the axis and elastically deforming the elastic protrusion. ).

  The wire retaining protrusion extends in a central direction from a peripheral edge portion of the fitting recess when viewed in plan, and overlaps with a pulley body of the pulley assembly fitted in the fitting recess, and the pulley body is the fitting recess. It is also preferable to serve as a pulley pull-out preventing protrusion that prevents the pulley from coming off.

  According to the first aspect of the present invention, the portion of the pulley assembly corresponding to the wire winding region of the pulley body (particularly the region where the tension load of the drive wire is applied most) is first fitted into the fitting recess, and then the pulley The part of the assembly corresponding to the non-winding region of the pulley body is fitted in the fitting recess, so that the pulley body is wound around the pulley body even though the tension load of the drive wire is applied to the pulley body. Problems such as disconnection of the drive wire and damage of the pulley assembly (pulley body) can be reliably prevented.

According to the second aspect of the present invention, since the pulley pull-out projection formed on the resin panel directly presses the pulley body of the pulley assembly, the pulley body is driven even when the window regulator sub-assembly is delivered (loaded). Even if a tension load of the wire is applied or an unexpected impact is applied to the pulley assembly, it is possible to reliably prevent the pulley body from coming off (disengaging) from the fitting recess of the resin panel.

  According to the third aspect of the present invention, when the window regulator sub-assembly is delivered (loaded), even if a tension load of the drive wire is applied to the pulley body or an unexpected impact is applied to the pulley assembly, the pulley body It is possible to reliably prevent the drive wire wound around the wire from coming out of the fitting recess.

  According to the invention which concerns on Claim 4, the ease of insertion to the insertion recessed part of a pulley assembly can be improved.

  According to the fifth aspect of the present invention, when the window regulator sub-assembly is delivered (loaded), even if a tension load of the drive wire is applied to the pulley body or an unexpected impact is applied to the pulley assembly, the pulley body It is possible to reliably prevent the pulley assembly having the detachment from the fitting recess of the resin panel. Further, since it is not necessary to separately form the wire retaining protrusion and the pulley retaining protrusion, the structure of the resin panel can be simplified and the manufacture can be facilitated.

It is the figure which looked at the window regulator by this invention from the vehicle inner side. It is the figure which looked at the window regulator by this invention from the vehicle front-back direction. It is sectional drawing which follows the IV-IV line of FIG. It is an enlarged plan view which shows the structure of the insertion recessed part of resin-made panels. It is an expansion perspective view which shows the structure of the insertion recessed part of resin-made panels. FIGS. 7A to 7D are process diagrams for fitting the pulley assembly in a state where the tension load of the drive wire is applied to the fitting recess of the resin panel.

In the figure, the window regulator 1 in the state of the window regulator sub-assembly before being assembled into the vehicle door is depicted. The directions in the following description are based on the directions indicated by the arrows in the figure.

  The window regulator 1 has an H shape when viewed macroscopically from the vehicle width direction (the vehicle outer side or the vehicle inner side) and is made of a resin that is slightly curved from the vehicle inner side toward the vehicle outer side when viewed from the vehicle longitudinal direction. A resin panel 10 made of a molded product is provided. A linear guide rail 11 and a guide rail 12 extending in the vertical direction are integrally formed on the vehicle front side and the vehicle rear side of the resin panel 10, respectively. On the guide rail 11 and the guide rail 12, a slider base 13 and a slider base 14 to which a window glass (not shown) is fixed are supported so as to be movable up and down.

  In the resin panel 10, fitting recesses 20 a, 20 b, 20 c, and 20 d are integrally formed so as to be positioned above and below the guide rail 11 and the guide rail 12. Pulley assemblies 30a, 30b, 30c, and 30d are fitted in the fitting recesses 20a, 20b, 20c, and 20d, respectively. The four fitting recesses 20a-20d and the four pulley assemblies 30a-30d have the same structure.

  A drive drum 15 and a motor unit 16 that rotationally drives the drive drum 15 in the forward and reverse directions are supported at the center of the resin panel 10. A drive wire W1 is wound around the drive drum 15. The drive wire W1 is connected to the slider base 13 after one end thereof is changed in direction by the pulley assembly 30b, and the other end is connected to the pulley assembly 30c. After changing direction, it is coupled to the slider base 14. The slider base 13 and the slider base 14 are coupled by a drive wire W2 (a member different from the drive wire W1) whose direction is changed by the pulley assembly 30a and the pulley assembly 30d. Accordingly, when the driving drum 15 is rotationally driven in the forward and reverse directions by the motor unit 16, the slider base 13 and the slider base 14 (window glass) are guided by the guide rail 11 and the guide rail 12 to move up and down. 1 and 2, the top dead center position of the slider base 13 and the slider base 14 in which the window glass (not shown) is fully closed with the window regulator 1 incorporated in the vehicle door, and the window glass (see FIG. 1). (Not shown) shows both the slider base 13 in the fully open state and the bottom dead center position of the slider base 14.

  With reference to FIGS. 4 to 6, the configuration of the fitting recess 20a and the pulley assembly 30a will be described in detail by representing the fitting recess 20a-20d and the pulley assembly 30a-30d having the same structure.

  As shown in FIGS. 4 to 6, the insertion recess 20a has a substantially circular shape when seen in a plan view, and a through hole 21 is formed at the center thereof. Rigid retaining protrusions (wire retaining protrusions, pulley retaining protrusions) 22 and elastic retaining protrusions (elastic protrusions) 23 are independent of the fitting recess 20a so as to face each other with the through hole 21 in the center portion sandwiched from the radial direction. Is formed. The elastic retaining protrusion 23 is made of a material that is softer and more easily elastically deformed than the rigid retaining protrusion 22 (for example, a leaf spring material). The rigid retaining protrusion 22 and the elastic retaining protrusion 23 are both included in a broad sense elastic member, and the terms “rigidity” and “elasticity” are used to indicate the relative hardness of both protrusions.

  The rigid retaining protrusion 22 and the elastic retaining protrusion 23 form a cantilever shape by the peripheral edge portion of the fitting recess 20a, and approach each other from the periphery of the fitting recess 20a toward the center when viewed in plan. It extends. The rigid retaining projection 22 extends in the horizontal direction from the peripheral portion of the fitting recess 20a toward the center portion, and the elastic retaining projection 23 seems to hang (bow) from the peripheral portion of the fitting recess 20a toward the center portion. It has an arc shape (curved shape) extending in the direction.

  As shown in FIG. 4, the pulley assembly 30 a includes a pulley body 31, a pulley bracket 32, and a nut member 33 that rotatably supports the pulley body 31 on the pulley bracket 32.

  The pulley body 31 has a bottom flange portion 311 and a top surface flange portion 312 that are all disk-shaped, and a wire guide groove 313 formed between the bottom surface flange portion 311 and the top surface flange portion 312. The drive wire W2 fixed to the slider base 13 and the slider base 14 is wound around the wire guide groove 313. An insertion hole 314 for inserting the nut member 33 is formed at the center of the pulley body 31.

  The pulley bracket 32 includes a pulley support surface 321 that supports the bottom flange portion 311 of the pulley body 31, and a fitting cylinder portion that extends downward from the center portion of the pulley support surface 321 and is fitted into the through hole 21 of the fitting recess 20a. 322. A standing wall portion 323 is formed on a part of the pulley support surface 321 in the circumferential direction, and this standing wall portion 323 is a wire winding region of the pulley body 31 (wire guide groove 313), particularly when viewed in plan view. The region where the tension load of the drive wire W2 is applied most is covered.

  The nut member 33 is composed of a shaft member that is inserted into the insertion hole 314 of the pulley body 31 and is caulked and fixed to the lower end portion of the fitting cylinder portion 322 of the pulley bracket 32. A flange portion 331 is formed at the upper end portion of the nut member 33 so as to come into contact with the top flange portion 312 of the pulley body 31. A bolt insertion hole 332 through which a coupling bolt (not shown) for incorporating the window regulator 1 in the sub-assy state into the vehicle door is inserted is formed in the center portion of the nut member 33.

  In a state where the pulley assembly 30a is fitted in the fitting recess 20a configured as described above, the rigid retaining protrusion 22 and the elastic retaining protrusion 23 sandwich the pulley body 31 of the pulley assembly 30a when viewed in plan. It overlaps with the pulley body 31. The distal end portion of the rigid retaining protrusion 22 faces the top surface flange portion 312 of the pulley body 31, and the distal end portion of the elastic retaining protrusion 23 is positioned inside the wire guide groove 313 of the pulley body 31. Thus, since the rigid retaining protrusion 22 and the elastic retaining protrusion 23 directly press the pulley body 31 of the pulley assembly 30a, the pulley body 31 is prevented from coming off (disengaging) from the fitting recess 20a of the resin panel 10. It can be surely prevented. In addition, the rigidity prevention protrusion 22 can improve the prevention function of the pulley assembly 30a having the pulley body 31, and the elastic prevention protrusion 23 can improve the ease of insertion of the pulley assembly 30a into the fitting recess 20a. Furthermore, the durability of the elastic retaining protrusion 23 is improved by setting the elastic displacement amount of the elastic retaining protrusion 23 small when the pulley assembly 30 a having the pulley body 31 is fitted into the fitting recess 20 a of the resin panel 10. Can do.

  The rigid retaining protrusion 22 is located on the farthest side from the drive drum 15 and the motor unit 16, and when viewed in plan, the wire winding region of the pulley body 31 (wire guide groove 313), particularly the tension load of the drive wire W2. Covers the area where the most is. Thereby, in addition to the prevention prevention function of the pulley assembly 30a which has the pulley main body 31, the rigid prevention protrusion 22 can be made to bear the prevention prevention function of the drive wire W2 wound around the pulley main body 31. The elastic retaining protrusion 23 is located on the side closest to the drive drum 15 and the motor unit 16, and when viewed in plan, the wire non-winding region of the pulley body 31 (wire guide groove 313), that is, the tension of the drive wire W2. It covers an area where no load is applied.

  The window regulator 1 configured as described above is assembled as follows. First, the slider base 13 and the slider base 14 are supported on the guide rail 11 and the guide rail 12 of the resin panel 10 so as to be movable up and down. Next, the drive wire W1 having one end and the other end fixed to the slider base 13 and the slider base 14 and the intermediate portion wound around the drive drum 15 is wound around the pulley body 31 of the pulley assembly 30b and the pulley assembly 30c. Then, the pulley assembly 30b and the pulley assembly 30c in a state where the tension load of the drive wire W1 is applied are fitted into the fitting recess 20b and the fitting recess 20c of the resin panel 10. At the same time, the drive wire W2 having one end and the other end fixed to the slider base 13 and the slider base 14 is wound around the pulley body 31 of the pulley assembly 30a and the pulley assembly 30d, and a tension load is applied to the drive wire W2. The pulley assembly 30a and the pulley assembly 30d are fitted into the fitting recess 20a and the fitting recess 20d of the resin panel 10.

  Now, with reference to FIGS. 7A to 7D, the process of fitting the pulley assembly 30a in a state where the tension load of the drive wire W2 is applied into the fitting recess 20a of the resin panel 10 will be described in more detail. .

  First, as shown in FIG. 7A, the drive wire W2 is wound around the wire guide groove 313 of the pulley body 31 of the pulley assembly 30a by less than one rotation (first step).

  Next, as shown in FIG. 7B, the axis of the pulley assembly 30a is tilted with respect to the axis of the fitting recess 20a, and the portion of the pulley assembly 30a corresponding to the wire winding region of the pulley body 31 is fitted into the fitting recess. Fit into 20a (second step). More specifically, the inclination angle of the axis of the pulley assembly 30a with respect to the axis of the insertion recess 20a is maximized, and the wire winding region of the pulley body 31 (particularly, the region where the tension load of the drive wire W2 is most applied) and the rigidity With the circumferential position of the retaining protrusion 22 shifted, a portion of the pulley assembly 30a corresponding to the wire winding region of the pulley body 31 is fitted into the fitting recess 20a, and then the axis fitting recess 20a of the pulley assembly 30a. The wire winding area of the pulley main body 31 (particularly, the area where the tension load of the drive wire W2 is applied most) and the circumferential position of the rigid retaining protrusion 22 are made to coincide with each other while gradually reducing the inclination angle with respect to the axis. Thereby, the part corresponding to the wire winding area | region of the pulley main body 31 among the pulley assemblies 30a is inserted in the insertion recessed part 20a below the rigid removal prevention protrusion 22. FIG.

  Next, as shown in FIG. 7C, the axis of the pulley assembly 30a is tilted in a direction coinciding with the axis of the fitting recess 20a, and a portion of the pulley assembly 30a corresponding to the non-winding region of the pulley body 31 is formed. Fit into the fitting recess 20a (third step). At this time, the elastic retaining protrusion 23 is pushed down by the pulley support surface 321 of the pulley bracket 32 to be elastically deformed, and is elastically restored within the wire guide groove 313 of the pulley body 31 to return to the free state. In this state, the rigid retaining protrusion 22 and the elastic retaining protrusion 23 overlap the pulley body 31 of the pulley assembly 30a, and the pulley body 31 is prevented from coming off (disengaging) from the fitting recess 20a (fourth step). ).

  Through the above steps, as shown in FIG. 7D, the window regulator 1 in the sub-assy state before being assembled into the vehicle door is completed. In the present embodiment, a portion of the pulley assembly 30a corresponding to the wire winding region of the pulley main body 31 (particularly, the region where the tension load of the drive wire W2 is applied most) is first fitted into the fitting recess 20a (second step). Thereafter, the portion of the pulley assembly 30a corresponding to the non-winding region of the pulley body 31 is fitted into the fitting recess 20a (third step), so that the tension load of the drive wire W2 is applied to the pulley body 31. However, it is possible to reliably prevent problems such as the drive wire W2 wound around the pulley body 31 coming off and the pulley assembly 30a (pulley body 31) being damaged.

  The window regulator 1 in the sub-assembled state couples the resin panel 10 to the door panel (inner panel) with a coupling bolt (not shown) inserted into the bolt insertion hole 332 of the nut member 33, and at the same time attaches to the slider base 13 and the slider base 14. By combining window glass (not shown), the window regulator 1 in a completed state is incorporated into the vehicle door.

  Here, the step of manufacturing the window regulator 1 in the sub-assy state and the step of incorporating the window regulator 1 in the sub-assy state into the vehicle door are performed in different manufacturing lines or different manufacturing plants. It is essential to sandwich the delivery process (carry-in process) of the window regulator 1 in the sub-assembly state. In this delivery process (carry-in process), the tension load of the drive wire W2 may be applied to the pulley body 31, or an unexpected impact may be applied to the pulley assembly 30a. In the present embodiment, the rigid retaining protrusion 22 and the elastic retaining protrusion 23 directly hold down the pulley body 31 of the pulley assembly 30a. It is possible to reliably prevent the resin panel 10 from coming off (disengaging) from the fitting recess 20a. In addition, it is possible to reliably prevent the drive wire W2 wound around the pulley body 31 from coming out of the fitting recess 20a.

  The advantageous effects of the fitting structure of the fitting recess 20a and the pulley assembly 30a described in the present embodiment can be obtained in exactly the same manner by the fitting structure of the fitting recess 20b-20d and the pulley assembly 30b-30d.

  In the above embodiment, the so-called double guide type window regulator 1 in which the slider base 13 and the slider base 14 are supported by the guide rail 11 and the guide rail 12 positioned in the longitudinal direction of the vehicle so as to be movable up and down has been described as an example. However, the present invention can be similarly applied to a so-called single guide type window regulator in which a single slider base is supported on a single guide rail so as to be movable up and down. When the present invention is applied to a single guide type window regulator, a mode in which the pulley assembly is supported above and below the guide rail, or a pulley drive is supported on the upper part of the guide rail while a wire drive mechanism is provided on the lower part of the guide rail. A supporting mode (so-called lower end drive) is possible. That is, the present invention is established as long as the pulley assembly is supported on at least one of the upper and lower sides of the guide rail of the resin panel.

  In the above embodiment, the case where the rigid retaining protrusion (wire retaining protrusion, pulley retaining protrusion) 22 and the elastic retaining protrusion (elastic protrusion) 23 are provided one by one has been described as an example. It is sufficient that at least one retaining protrusion 23 is provided, and an embodiment in which two or more of these one or both are also possible.

  In the above embodiment, when the distal end portion of the rigid retaining protrusion 22 is opposed to the top flange portion 312 of the pulley body 31 and the distal end portion of the elastic retaining protrusion 23 is positioned inside the wire guide groove 313 of the pulley body 31. Has been described as an example. However, the aspect in which the rigid retaining protrusion 22 and the elastic retaining protrusion 23 are provided is not limited thereto. For example, both the rigid retaining protrusion 22 and the elastic retaining protrusion 23 are opposed to the top flange portion 312 of the pulley body 31. Is also possible.

  In the above embodiment, when viewed in plan, the distal end portion of the rigid retaining protrusion 22 extends to a position where it overlaps with the top flange portion 312 of the pulley body 31, but is not limited thereto, and when viewed in plan In addition, a mode in which the distal end portion of the rigid retaining protrusion 22 extends to the vicinity of the peripheral edge portion of the top flange portion 312 of the pulley body 31 is also possible.

  In the above embodiment, the case where the rigid retaining protrusion 22 serves as both the pulley retaining protrusion and the wire retaining protrusion has been described as an example. However, the insertion recesses 20a, 20b, 20c, and 20d of the resin panel 10 are described. A rigid retaining protrusion as a pulley retaining protrusion and a rigid retaining protrusion as a wire retaining protrusion may be separately formed on the peripheral edge.
