Description

  The present invention relates to a fixing structure for fixing a component to a door panel.

Parts are attached to the doors of automobiles, and typical examples include a window regulator that drives the window glass up and down, a speaker, a door lock, and an inner handle.
It is also possible to attach each of these parts directly to the door panel. However, in that case, it is difficult to manage each component, and the work becomes complicated. On the other hand, there is a method in which all parts are attached to a panel-like fixture and attached to the door as a module. However, in the automobile industry, there is a demand for further weight reduction and cost reduction, and it is desired to attach components without the fixture itself.

  In view of the above-described problems, an object of the present invention is to provide a component fixing structure that does not require a complicated mounting process and can be reduced in weight and cost.

The fixing structure of the present invention is a part fixing structure for attaching a part temporarily placed on a conveying jig to a panel from the jig, and includes a part having a through hole and a jig for temporarily placing the part. The assembly set consisting of a tool and a temporary placement pin that is inserted through one opening of the through hole of the component and connects the component and the jig is aligned with the axis of the through hole of the component and the axis of the mounting hole of the panel. In this manner, the fixing pin is pushed out from the through hole of the part by inserting the fixing pin from the other opening of the through hole through the mounting hole so as to be separated from the jig, and the part is fixed to the panel. It is characterized by doing.
In such a fixing structure, a female screw is formed in the through hole of the component, and a male screw that is screwed to the female screw is formed on the temporary placement pin and the fixing pin. It is preferable that an engagement portion capable of transmitting torque around the shaft center is formed at the tip of the mounting pin. Furthermore, it is preferable that the component is a pulley of a window regulator and the panel is a door panel.
Further, in this fixing structure, a female screw is formed in the through hole of the component, a male screw that is screwed to the female screw is formed in the fixing pin, and the tip of the fixing pin and the temporary placement pin An engaging portion capable of transmitting torque around the axis is formed at the tip of the shaft, and the temporary placement pin inserted into the through hole may be held by a magnetic force.

  The fixing structure of the present invention is a part fixing structure for attaching a part temporarily placed on a conveying jig to a panel from the jig, and a part having a through hole and a jig temporarily placing the part. The assembly set consisting of a tool and a temporary placement pin that is inserted through one opening of the through hole of the component and connects the component and the jig is aligned with the axis of the through hole of the component and the axis of the mounting hole of the panel. In this manner, the fixing pin is pushed out from the through hole of the part by inserting the fixing pin from the other opening of the through hole through the mounting hole so as to be separated from the jig, and the part is fixed to the panel. Therefore, it is easy to attach the component to the panel. In addition, since the jig can be reused by returning it to the manufacturer after use, the cost can be reduced and the assembled panel can be reduced in weight.

FIG. 3 shows a window regulator 40 having a pulley having a fixing structure according to the present invention.
As shown in FIG. 3, the window regulator 40 is attached to the door panel P, and includes four pulleys 10, an inner cable 41 routed in the pulleys, and a window glass 42 that is fixed to the inner cables and is fixed to the window cables 42. The carrier plate 43 that supports the inner cable and the drive device 44 that drives the inner cable back and forth. The window regulator does not use a guide member that supports the movement trajectory of the carrier plate, and the window glass 42 is guided up and down by the window glass run R of the door D. Further, the window regulator 40 is such that only the pulley 10 and the driving device 44 are fixed to the door panel P.

FIG. 1a shows the state (fixed state) of the pulley 10 of the window regulator when it is fixed to the door panel.
The pulley 10 includes a cylindrical pulley shaft 12 having a center hole 11 in which a female screw is formed, a cylindrical pulley body 14 having a groove 13 disposed on the outer periphery thereof, and a U-shape that covers the pulley shaft and the pulley body. And a bolt 16 formed with a male screw inserted into the center hole 11 of the pulley shaft via the door panel P.

  A flange 17 is formed at the end of the pulley shaft 12 on the bolt mounting side, and the other end of the pulley shaft 12 is caulked to the pulley bracket 15. As a result, the pulley body 14 is held so as to be rotatable with respect to the pulley shaft 12 and not coming off the pulley shaft 12. The pulley 10 is attached to an attachment hole 18 formed in the convex portion 18a of the door panel P. Thus, by attaching the pulley 10 to the convex part 18a of the door panel P, the vertical movement space of the carrier plate connected with the pulley 10 via the cable is ensured. Further, the pulley bracket 15 prevents the cable from coming out of the groove 13 of the pulley body 14.

  A communication hole 20 concentric with the center hole 11 of the pulley shaft is formed in the bottom portion 19 of the pulley bracket. The pulley 10 is attached so that the center of the U-shaped opening of the pulley bracket 15 and the attachment hole 18 of the door panel P are aligned. Further, a claw 22 that engages with the door panel P is formed at one end of the opening of the pulley bracket 15. This prevents the pulley shaft 12 from rotating together when the bolt 16 is inserted into the center hole 11 and the bolt 16 is screwed together.

  Further, a protrusion 25 is formed at the tip of the bolt 16. This protrusion 25 is engaged with a slit 33 at the tip of a temporary placement pin, which will be described later. The length of the threaded portion of the bolt 16 and the threaded portion of the pulley shaft are formed to be substantially the same.

  With this configuration, the bolt 16 and the pulley shaft 12 are fixed by inserting the bolt 16 into the center hole 11 of the pulley shaft 12, and further, the bolt 16 and the pulley shaft 12 are disposed between them. And the door panel P interposed therebetween.

FIG. 1b shows a state in which the pulley 10 from which the bolt 16 has been removed is temporarily placed on the plate-like jig 30, that is, a state of the pulley in the assembly set 40a before being attached to the door panel P (temporary placement state).
At this time, the bottom 19 of the pulley bracket 15 is in contact with the jig 30 so that the center hole 11 of the pulley shaft 12 of the pulley 10 and the temporary placement hole 31 of the jig 30 overlap. That is, the pulley 10 is disposed on the jig 30 such that the U-shaped opening of the pulley bracket faces the outside. And the pulley 10 and the jig | tool 30 are connected by inserting the temporary placement pin 32 in which the external thread was formed in the center hole 11 of a pulley shaft via the jig | tool 30, and the pulley 10 is attached to the jig | tool 30. It is done. In this state, the pulley body 14 cannot be removed from the pulley shaft 13 because of the flange 17.

  A slit 33 is formed at the tip of the temporary placement pin 32 to engage with the protrusion 25 of the bolt 16 described above. The slit 33 is configured to protrude from the range of the screw portion of the center hole when the temporary pin 32 is inserted into the center hole 11. Since the temporary placement pin 32 is formed in this way, the bolt 16 is inserted from the opening of the center hole 11 on the side where the temporary placement pin 32 is not inserted, as will be described later. The slit 33 can be engaged. Two or three slits 33 may be formed so as to intersect.

  A method of attaching the pulley 10 attached to the jig 30 is shown in FIG. First, the pulley temporarily placed on the jig 30 is disposed so as to be positioned in the mounting hole 18 of the door panel. Next, the bolt 16 is inserted into the center hole 11 of the pulley shaft through the door panel P (see FIG. 2a). Then, the bolt 16 is screwed to the back of the center hole 11 of the pulley shaft. Thereby, the pulley 10 is attached to the door panel P, the temporary placement pin 32 is pushed out from the center hole 11 of the pulley shaft, and the jig 30 is removed from the pulley (see FIG. 2b).

  As a conveyance jig 30 for temporarily placing (accommodating) the window regulator 40 including the pulley 10, there is a rectangular panel type as shown in FIG. 45b and a concave storage portion 46 formed between the mounting portions thereof, and a handle 47 formed at the upper end thereof. The jig 30 is formed so that the upper mounting portion 45a and the lower mounting portion 45b are slightly inclined (see FIG. 4b). By providing the angle in this way, the window regulator used for the curved window glass can be stored in the same structure as the structure attached to the door panel.

Two temporary placement holes 31 are formed in each of the upper and lower mounting portions 45a and 45b, and three drive device temporary placement holes 31a are formed to temporarily place the drive device in the storage portion 46. . Further, the storage portion 46 is formed with a hole 48 for cost reduction, material saving and weight reduction.
The jig 30 is made of, for example, a metal such as stainless steel or aluminum (Al), or a synthetic resin such as polypropylene (PP) or polybutylene terephthalate (PBT).

  Since it is comprised in this way, the window regulator 40 can be integrated and accommodated. Further, the collection after the window regulator is attached and the subsequent conveyance are also easy because of the panel type. FIG. 5 shows an assembly set 40 a in which the window regulator 40 is temporarily placed on the jig 30. As described above, the jig 30 can be temporarily placed in a structure substantially the same as the structure in which the window regulator is attached to the door panel.

As shown in FIGS. 6 a and 6 b, the assembly set 35 temporarily placed on the jig 30 accommodates the temporary placement pins 32 so as to be movable up and down, and includes a storage portion 49 fixed to the jig 30. .
Since it is configured in this way, even if the temporary placement pin 32 is pushed out by the bolt 16, the temporary placement pin 32 is not separated from the jig 30. Therefore, it is easy to collect the assembly set 45a after removing the pulley 10.

FIG. 7 shows a state where the pulley 10 is temporarily placed on the jig 50 by the temporary placement pins 51.
In this jig 50, instead of the temporary placement hole 31 of the jig 30 of FIG. 4, the temporary placement pin 51 is welded to the surface of the mounting portion to which the pulley 10 is fixed, and the periphery of the temporary placement pin 51. A magnet 52 is fixed to the magnet.

  Since the jig 50 is configured in this way, the pulley 10 is temporarily placed in the center hole 11 of the pulley shaft 12 of the pulley 10 with the bottom 19 of the U-shaped pulley bracket and the jig 50 in contact with each other. A pin 32 is inserted and temporarily placed (see FIG. 6a). Here, the bottom portion 19 of the pulley bracket is attracted to the magnet 52 of the jig.

  Next, the jig 50 is brought into contact with the door panel P (see FIG. 7a), and in this state, the bolt 16 is inserted into the center hole 11 of the pulley shaft 12 through the door panel P (see FIG. 7b). Thereby, the temporary placement pin 51 is pushed out, and at the same time, the jig 50 is separated from the pulley 10.

FIG. 8 a shows the state of the pulley 10 temporarily placed on the jig 60.
As shown in FIG. 8 c, the jig 60 has a temporary placement hole 62 in a groove shape and continues to the upper end. In addition, a slide portion 63 that slides and stores the temporary placement pin 61 is provided on the back surface of the temporary placement hole 62. The slide portion 63 is formed with an opening 63 a for operating the temporary placement pin 61.
The temporary placement pin 61 includes a slider 64 that slides on the slide portion 63 and a pin body 65 that is provided at the center thereof so as to be movable up and down. Support walls 64 a are formed at both ends of the slider 64. The height of the support wall 64 a is formed to be substantially the same as the stroke length of the pin body 65.

  With this configuration, the assembly set 66 inserts the pin main body 65 of the temporary placement pin 61 into the temporary placement hole 62 of the jig 60 and simultaneously slides the slider 64 onto the slide portion 63. At this time, since the slider 64 is provided with the support wall 64a, the pin body 65 can perform a stroke necessary for temporarily placing and removing the pulley 10, and the pin body 65 is not separated from the slide portion 63. Further, in this state, the temporary setting hole 62 is brought into contact with the central hole 11 of the pulley shaft 12 of the pulley 10, and the pin main body 65 of the temporary setting pin is inserted into the central hole 11 of the pulley shaft, thereby forming an assembly set 66.

Moreover, when attaching the pulley 10 to the door panel P from the assembly set 66, the pin main body 65 is pushed out by inserting the volt | bolt 16 (refer FIG. 8c). However, since the slider 64 is supported by the slide portion 63, the temporary placement pin 61 is not separated from the jig 60. Further, as shown in FIG. 8c, a claw 67 is provided at the upper end of the groove to prevent the temporary placement pin 61 from coming off by bending.
Such a structure is preferable when the window regulator attached as shown in FIG. 8d is used for a curved window glass. That is, in this case, the pulley pushes the temporary placement pin in the direction of the arrow in parallel with the glass surface, but the pitch (stroke) of the temporary placement pins arranged at the top and bottom at that time is increased by the inclination. In this structure, the temporary placement pin can be moved up and down along the groove, and the increase in pitch can be eliminated.

Next, a structure for attaching the threaded component 70 to the panel P will be described with reference to FIGS. 9a to 9c.
The threaded component 70 of FIG. 9a includes a through hole 71 having a female thread. The assembly set 74 is assembled by inserting the temporary placement pin 73 through the jig 72 from one opening of the through hole.
By inserting a bolt 75 into the assembly set 74 through the panel P from the other opening of the through hole, the threaded component 70 carried by the jig 72 can be attached to the panel P.
As described above, the fixing structure of the present invention can easily attach components to large articles such as automobile doors, and can attach only necessary components. Examples of such parts include a window regulator attached to the door panel, a speaker attached to the door panel, a door lock, an inner handle, and the like.
