Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guide member mounting structure for a drive device in a wind regulator of an automobile.

Conventionally, this type of drive device houses a drum pivotally supported by a drum shaft in a case with one drive side open, and wires for lifting and lowering are wound around this drum, and wires for lifting and lowering are wound around the drum. It has a structure in which it is connected to a drive source such as a motor or an operating handle.

In order to guide the two wires extending from the inside of the case, a guide member made of synthetic resin is used, for example, as shown in FIG. A protruding shape was fitted into a case (not shown).

However, with this plug shape,
The drawback was that the mold used for molding was complicated, resulting in high costs.

The present invention aims to provide a guide member mounting structure for a wind regulator that can reduce manufacturing costs by making the guide member a shape that facilitates the production of a molding die.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 6. First, the general structure of the wind regulator will be described, and then the guide member will be described.

Reference numeral 1 denotes a rail plate installed in an automobile door and running approximately vertically.A carrier plate 2 supporting a window glass (not shown) slides vertically along the rail 1a formed on the right side edge of the rail plate 1. It is attached so that it can move freely.

3 is a board attached to the inner panel,
A motor 4 and a decelerator 5 connected to the motor 4 and consisting of a worm and a worm wheel are installed on the inside of the vehicle, sandwiching a window hole (not shown) made in the board 3, and the output of the decelerator 5 is A drive device 6 is attached to the outer side of the board 3 in conjunction with the shaft.

The drive device 6 houses a drum 8 pivotally supported by a drum shaft 8a in a substantially horseshoe-shaped case 7 that opens toward the inside of the vehicle. Further, from the upper end surface of the case 7, the free ends of the lifting wire 9 and the pulling wire 10, whose proximal ends are wound around the drum, are directed toward the carrier plate 2 through cable conduits 11 and 12, respectively. It has been extended.

Although the guide member 13 of the present invention is interposed between the case 7 and the proximal ends of the cable conduits 11 and 12,
This structure will be explained in detail later.

The tip of the wire 9 heads downward after passing around a guide roller 14 pivotally attached to the upper end of the rail plate 1, and its end 9a is fixed to the center of the carrier plate 2.

The tip of the wire 10 is inserted into the guide groove 15a of the guide plate 15 at the upper end of the rail plate 1, then directed downward and inserted into the semicircular guide groove 16a of the guide plate 16 at the lower end of the rail plate 1. After that, the terminal 10a is fixed in the center of the carrier plate 2 at a position adjacent to the terminal 9a.

Thus, by the forward and reverse rotation of the motor 4, the drive device 6 winds up or unwinds the wires 9 and 10, respectively, and the carrier plate 2 reciprocates up and down on the rail 1a. , car windows can now be opened and closed.

As shown in FIG. 5, the guide member 13 is integrally molded from a synthetic resin material using a mold.
A pair of left and right plugs 17 and 18 are connected.
A pair of left and right cylindrical portions 17a, 18a, which are approximately cylindrical with a bottom, are arranged side by side at intervals such that their respective axes are parallel to each other;
Mounting plates 17b are integrally connected to the base of the tube 8a and are arranged in a V-shape so as to form a desired angle with respect to the axial direction of the cylinder portion.
18b, and a thin flexible hinge portion 19 that connects the adjacent end surfaces of the mounting plates 17b and 18b.

In FIG. 4, the mounting plate 1 of the plug 17 on the left
Grooves 20 that are approximately U-shaped when viewed from the front are provided at the left end, lower end surface, and right end surface along the center line of the thickness of the plate 7b.
A split groove 23 is cut from the top surface so as to communicate with both the recessed hole 21 of the cylindrical portion 17a and the wire insertion hole 22 passing through the bottom of the recessed hole 21.

Similarly, a U-shaped groove 24 is formed in the mounting plate 18 of the right plug 18 along the center line of the plate thickness, and a wire insertion hole 2 is formed in the bottom of the concave hole 25 of the cylindrical part 18a.
6 is drilled.

Reference numerals 27 and 28 are engagement protrusions connected to the inner end surfaces of the upper surfaces of the mounting plates 17b and 18b of the plugs 17 and 18, respectively.

What is shown in FIG. 6 is a case 7 made of a molded metal plate to which the guide member 13 is attached, and includes a bottomed cylindrical drum storage part 7a for storing the drum 8 and a rectangular box-like wire insertion part 7b. A plurality of flanges 30 having mounting holes 29 are provided in series on the opening edge of the drum storage portion 7a.

A pair of short and long U-shaped notch grooves 32 and 33 are cut into the end surface 31 of the wire insertion portion 7b and are open at the top.

Therefore, in order to attach the guide member 13 to the case 7, the plug 1 of the guide member 13 must be
7 so that the groove 20 fits into the notch groove 32, and the plug 18 and the groove 24 fit into the notch groove 33.
The guide member 13 may be inserted into the case 7 in FIG. 6 from above.

During this installation, as shown by the imaginary line in FIG.
The cylindrical portion 18a can be attached at a desired angle.

As explained in detail above, the guide member mounting structure of the wind regulator of the present invention is such that the guide member is connected to a cylindrical part having a wire insertion hole and a mounting plate connected to the base end thereof and having a groove on the circumferential surface. When molding the guide member, the guide member, whose respective axes of the pair of cylindrical parts are parallel to each other, is connected to the case by a flexible hinge. It has a structure that is inserted into a notched groove.

Therefore, there is a degree of freedom between the plugs connected by the flexible hinge portion, making the installation work easier and the work time shorter.

Furthermore, since the respective axes are parallel during mold molding, there is an advantage that costs can be reduced by simplifying the mold structure of the guide member.

Further, since the intersection angle of the cylindrical portion of the guide member can be freely set, there is an advantage that versatility is improved and the product can be made smaller and lighter.
