JP 2006-28973 A

Since the guide rail of Patent Document 1 is made of metal, it is necessary to apply grease to the surface of the guide rail (the entire sliding contact portion with the slider). If grease is not applied, the sliding resistance of the slider made of synthetic resin with respect to the guide rail is increased, so that the sliding operation of the slider becomes unsmooth. Furthermore, wear of the sliding contact portion between the guide rail and the slider is promoted.
However, if grease is applied, there is a risk that the hand will be soiled by the grease when the guide rail is assembled to the vehicle door. Furthermore, since it is necessary to apply grease to the guide rail, the manufacturing cost of the guide rail is increased accordingly.

  The present invention provides a vehicle window regulator device that can smoothly slide a slider without applying grease to the surface of the guide rail and that can effectively suppress wear of a sliding contact portion between the guide rail and the slider. The purpose is to do.

  The window regulator device for a vehicle according to the present invention includes a slider fixed to a slide window that moves up and down relative to a door panel of a vehicle door, and is fixed to the door panel and extends in the ascending / descending direction, and slidably supports the slider. Guide rail, at least one wire turning member provided on the guide rail, a drive wire that moves around the wire turning member and moves up and down together with the slider, and a drive that moves the drive wire up and down A window regulator device for a vehicle comprising a drum, wherein the guide rail includes a resin sliding contact portion that extends in the extending direction and is longer in the extending direction than the slider, and is in sliding contact with the slider. It is said.

  The slidable contact portion may be a protrusion that protrudes toward the slider.

  You may form the hollow part extended along the extension direction of this protrusion in the inside of the said protrusion.

In the present invention, since the sliding contact portion of the guide rail is made of resin, the slider slides smoothly with respect to the guide rail without applying grease to the sliding contact portion.
Further, since it is not necessary to apply grease, there is no possibility that the hand is soiled by the grease when the guide rail is assembled to the vehicle door, and the manufacturing cost of the guide rail can be further reduced.
Moreover, since the sliding contact portion formed on the guide rail is longer than the slider, the entire sliding contact portion does not contact the slider at the same time, and each part (part) of the sliding contact portion sequentially contacts the slider. Therefore, the sliding contact portion is not easily worn.

  If the sliding contact portion is a ridge as in the second aspect of the invention, the sliding operation of the slider with respect to the guide rail becomes smoother.

  According to the third aspect of the present invention, since the ridge formed with the hollow portion can be elastically deformed, when the slider (slide window) rattles in the vehicle width direction or the front-rear direction, the rattling is reduced. It can be absorbed by the ridge formed.

Three protrusions are integrally provided on the outer peripheral surface of the drum cover wall 31, female screw holes 33 are formed in the two protrusions, and the remaining one protrusion penetrates the protrusion. A screw insertion hole 34 is formed.

The guide rail unit 21 is slidably attached with a slider 40 which is an integrally molded product made of resin. As a resin material constituting the slider 40, for example, PA66-GF can be used.
The slider 40 is a member having a cross-sectional shape shown in the figure, and includes a fitting groove 41 having an L-shaped cross section that extends in the up-down direction and opens at both the upper and lower end surfaces and the rear end surface. The slider 40 further includes an auxiliary fitting groove 42 extending in the vertical direction and a wire fixing hole 43 penetrating the slider 40 in the vertical direction. In addition, a bolt insertion hole 44 that penetrates the protrusion in the vehicle width direction is formed in the protrusion formed at the front end portion of the slider 40.

One end of a first wire (drive wire) 46 and a second wire (drive wire) 50 is attached to the slider 40.
A stopper 47 having a larger diameter than the first wire 46 is fixed to one end of the metal first wire 46, and another stopper (not shown) is attached to the other end. On the other hand, a stopper 51 having a diameter larger than that of the second wire 50 is fixed to one end of the metal second wire 50, and another stopper (not shown) is attached to the other end.
Both the first wire 46 and the second wire 50 are attached to the slider 40 separated from the guide rail unit 21. Specifically, the end of the first wire 46 opposite to the stopper 47 is inserted into the wire fixing hole 43 from above and the end of the second wire 50 opposite to the stopper 51 is inserted downward. The wire is inserted into the wire fixing hole 43 in a state where the wire is fixed.

Then, an integrated body composed of the slider 40, the first wire 46, and the second wire 50 is attached to the guide rail 22. Specifically, this integrated object is approached from above to the upper end portion of the guide rail 22, the upper end portion of the front half of the guide rail 22 is fitted into the fitting groove 41 from below, and the guide wall 22 b on the rear side is fitted. The upper end is fitted into the auxiliary fitting groove 42 from below. Then, since the inner surface of the fitting groove 41 comes into contact with the upper ends of the first and second protrusions 23 and 24, the relative movement in the front-rear direction and the relative movement in the vehicle width direction of the slider 40 with respect to the guide rail 22 is restricted. The
The connection holes formed in the lower end surface of the pulley support member 25 and the connection holes 32 formed in the upper end surface of the drum housing 28 are formed in the upper and lower ends of the guide rail 22 integrated with the slider 40 in this way. The guide rail unit 21 including the guide rail 22, the pulley support member 25, and the housing 28 is assembled by fitting and fixing each.
Note that when the slider 40 is attached to the guide rail 22, the unitary object composed of the slider 40, the first wire 46, and the second wire 50 is approached from below to the lower end of the guide rail 22, The lower end portion of the front half may be fitted into the fitting groove 41 from above, and the lower end portion of the rear guide wall 22b may be fitted into the auxiliary fitting groove 42 from above. Further, the slider 40 may be attached to the guide rail 22 after one of the pulley support member 25 and the housing 28 is fixed to the guide rail 22.

An intermediate portion of the first wire 46 is wound around a wire support groove that is recessed in the entire peripheral surface of the pulley (wire changing member) 53. The pulley 53 is rotatably supported by a metal bracket 54 via a rotation support shaft 55 extending in the vehicle width direction. The bracket 54 has a bolt (not shown) protruding on the back surface thereof inserted into the through-mounting hole 26 from the outside of the vehicle, and a nut (not shown) is screwed to the tip of the bolt protruding to the inside of the pulley support member 25. By doing so, it is attached to the pulley support member 25.
The end of the first wire 46 on the stopper 47 side and the end of the second wire 50 on the stopper 51 side are fixed to the drive drum 57. A wire support groove is provided in the entire peripheral surface of the drive drum 57, and two locking recesses 58 communicating with the wire support groove are provided in the side surface of the drive drum 57 (one in FIG. 2). Only one is shown). The stopper 47 and the stopper 51 are fitted in the two locking recesses 58 so as to be respectively removed, and the vicinity of the end portion of the first wire 46 on the stopper 47 side and the end portion of the second wire 50 on the stopper 51 side. The vicinity is wound around the wire support groove of the drive drum 57 (the winding directions of the first wire 46 and the second wire 50 are opposite to each other). The drive drum 57 is housed in the drum mounting recess 29 of the housing 28 in a state where the inner end of the center through hole is rotatably fitted to the rotation support projection 30.
The drive drum 57 is rotated by the power of the motor 60 fixed to the motor bracket 61 that is a metal disk. The motor bracket 61 includes a rotation support shaft 62 that protrudes toward the inner side of the vehicle, and two through holes 63 that are respectively formed in two protrusions that protrude outward in the radial direction. In the motor bracket 61, the rotation support shaft 62 is fitted to the outer side end portion of the center through hole of the drive drum 57 so as to be relatively rotatable, and the bolt 64 inserted into the two through holes 63 from the outside of the vehicle is inserted into the female screw hole 33. By being screwed together, the drum cover 28 is fixed to the drum housing 28 in contact with the vehicle outer surface. When the motor bracket 61 is fixed to the drum housing 28, the drive drum 57 supported by the rotation support shaft 62 can be rotated in the drum mounting recess 29, and the output rotation shaft of the motor 60 is connected via a speed reduction mechanism (not shown). And linked to the drive drum 57.

The guide rail unit 21, slider 40, first wire 46 (stopper 47), second wire 50 (stopper 51), pulley 53 (bracket 54, rotation support shaft 55), drive drum 57, motor 60, motor bracket described above. 61 and the bolt 64 are components of the window regulator device 20. The window regulator device 20 unitized as described above is disposed in the regulator housing space 13 through the working opening 12a formed in the inner panel 12, and a pair of through holes 27 formed in the upper end of the pulley support member 25. The bolt 65 inserted from the vehicle interior side is screwed into the female screw hole of the fixing member fixed to the vehicle inner side surface of the outer panel 11, and the bolt 66 inserted from the vehicle outer side to the screw insertion hole 34 is fixed to the vehicle outer surface of the inner panel 12. The outer panel 11 and the inner panel 12 are fixed by screwing into the female screw holes of the fixing member.
Further, when the window holder 71 is fixed to the lower edge portion of the slide window 16 and the slide window 16 is lowered and the window holder 71 is opposed to the slider 40, the tip of the bolt 70 penetrated into the bolt insertion hole 44 from the inside of the vehicle. Are screwed into a female screw hole (not shown) of the window holder 71 to fix the slider 40 and the window holder 71 to each other. When a door trim (not shown) is attached to the inner surface of the inner panel 12, the vehicle door 10 is completed.

  When the window switch provided on the door trim of the vehicle door 10 is operated from the initial position (neutral position) to the opening operation direction, the motor 60 that receives current from the power source (not shown) rotates in the forward direction and the drive drum 57 is shown in FIGS. 3 counterclockwise. Then, the first wire 46 is discharged from the drive drum 57, while the second wire 50 is wound up by the drive drum 57, and the portion of the first wire 46 and the second wire 50 located on the front side of the pulley 53 causes the pulley 53 to be wound. The first wire 46 and the second wire 50 are lowered while being rotated, and the portion located on the rear side of the pulley 53 is raised, so that the slider 40 and the slide window 16 are lowered along the guide rail 22. On the other hand, when the window switch is operated in the closing operation direction, the motor 60 receiving the current from the power source reverses and the drive drum 57 rotates in the clockwise direction in FIGS. Therefore, while the second wire 50 is discharged from the drive drum 57, the first wire 46 is wound up by the drive drum 57, and the portion of the first wire 46 and the second wire 50 located on the front side of the pulley 53 causes the pulley 53 to be wound. The first wire 46 and the second wire 50 are raised while being rotated, and the portion of the first wire 46 and the second wire 50 located behind the pulley 53 is lowered, so that the slider 40 and the slide window 16 are raised along the guide rail 22. If the window switch is returned to the initial position, the supply of current from the power source to the motor 60 is cut off, so that the motor 60 stops rotating.

In the present embodiment described above, since the guide rail 22 is a resin-made extruded product, the weight can be reduced as compared with the case where the guide rail main body 22c is made of metal (for example, iron), and (resin injection molding). It is possible to reduce the manufacturing cost (compared with the product).
Moreover, since the guide rail 22 is an extrusion molded product, the manufacturing cost is low despite being a two-color molded product using two types of resin raw materials.

Further, the first protrusion 23 and the second protrusion 24 of the guide rail 22 are made of a resin raw material (POM) having a sliding resistance smaller than that of the resin raw material constituting the guide rail main body 22c. Therefore, when the comparison (test) is performed under the same conditions (the same temperature, humidity, etc.) as the first protrusion 23 and the second protrusion 24 made of the same material as the guide rail body 22c, the slider Since the sliding resistance of the 40 first protrusions 23 and the second protrusions 24 is reduced, the slider 40 can be smoothly slid relative to the guide rail 22.
Furthermore, since the guide rail body 22c is made of PP-LGF (PP containing glass fiber), the guide rail body 22c exhibits high rigidity. Therefore, the guide rail 22 can support the slider 40 in a stable state.
Moreover, since the first ridge 23, the second ridge 24, and the slider 40 are all made of resin, it is not necessary to apply grease to the guide rail 22 in order to make the slider 40 slide smoothly. Therefore, there is no possibility that the hand is soiled by the grease when the guide rail 22 is assembled to the vehicle door 10. Furthermore, since no grease is required, the manufacturing cost of the guide rail 22 can be reduced accordingly.

In addition, since the first and second ridges 23 and 24 formed on the guide rail 22 are longer in the vertical direction than the slider 40, the entire first and second ridges 23 and 24 are sliders when the slider 40 slides. The parts (parts) of the first and second ridges 23 and 24 do not contact the slider 40 at the same time, and sequentially contact the slider 40. Therefore, the first protrusion 23 and the second protrusion 24 are not easily worn (if the slider 40 is formed with a sliding contact portion corresponding to the first protrusion 23 and the second protrusion 24, the slider 40 slides. (Sometimes, the entire sliding contact portion is always in contact with the guide rail 22, so that the sliding contact portion is easily worn).
Further, since the deformation-permissible grooves 23a are formed in the two first ridges 23, the front first ridge 23 can be elastically deformed in the front-rear direction, and the rear first ridge 23 is in the vehicle width direction. It can be elastically deformed. Therefore, when the slider 40 (slide window 16) rattles in the vehicle width direction or the front-rear direction, this rattling can be absorbed by the two first protrusions 23.

As mentioned above, although this invention was demonstrated using the said embodiment, this invention can be implemented, giving various changes.
For example, the guide rail body 22c and the slider 40 may be made of metal (for example, iron).
Further, the first and second ridges 23 and 24 and the guide rail body 22c may be formed separately and then integrated. For example, even if the resin guide rail main body 22c is formed by primary injection molding, and the first protrusion 23 and the second protrusion 24 are formed on the surface of the guide rail main body 22c by secondary injection molding (insert molding). Good. Alternatively, the metal guide rail main body 22c may be formed by press molding or the like, and the first protrusion 23 or the second protrusion 24 may be formed on the surface of the guide rail main body 22c by injection molding (insert molding).
Moreover, you may form a deformation | transformation tolerance groove | channel (hollow part) not only in the 1st protrusion 23 side but in the 2nd protrusion 24 side.
Further, the first protrusion 23 (second protrusion 24) penetrates the inside of the first protrusion 23 (second protrusion 24) in the vertical direction as a hollow portion instead of the deformation-permissible groove (the side portion is exposed). No) A through hole may be provided.
Moreover, you may make the cross-sectional shape of the 1st protrusion 23 and the 2nd protrusion 24 into a shape different from the above-mentioned thing.

さらにガイドレール２２を三種類以上の樹脂原料によって成形してもよい。この場合も、第１突条２３及び第２突条２４を構成する樹脂原料の方が、ガイドレール本体２２ｃを構成する樹脂原料よりも、スライダ４０との摺動抵抗が小さくなるように樹脂原料を選択する。
またプーリ５３の代わりに、プーリ支持部材２５に対して回転不能で周面にワイヤ支持溝を有する固定式ワイヤガイドを固定してもよい。
さらにワイヤ変向部材を複数設けても良い。例えば、ガイドレールユニット２１の上下両端部に一対のワイヤ変向部材を設け、駆動ドラム５７をワイヤ変向部材とは異なる場所に設けてもよい。 You may shape | mold the guide rail main body 22c, the 1st protrusion 23, the 2nd protrusion 24, and the slider 40 using the resin raw material different from the above. However, also in this case, the resin raw material constituting the first ridge 23 and the second ridge 24 is resin so that the sliding resistance with the slider 40 is smaller than the resin raw material constituting the guide rail body 22c. Select raw materials. For example, the following table combinations are possible. In addition, you may put glass fiber in the resin raw material of the slider 40 as needed.

Further, the guide rail 22 may be formed of three or more kinds of resin raw materials. Also in this case, the resin raw material constituting the first ridge 23 and the second ridge 24 is such that the sliding resistance with the slider 40 is smaller than the resin raw material constituting the guide rail body 22c. Select.
Further, instead of the pulley 53, a fixed wire guide that cannot rotate with respect to the pulley support member 25 and has a wire support groove on the peripheral surface may be fixed.
Further, a plurality of wire turning members may be provided. For example, a pair of wire turning members may be provided at the upper and lower ends of the guide rail unit 21 and the driving drum 57 may be provided at a location different from the wire turning member.
