DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor mounting structure and a power window regulator employed in, for example, a power window device.

[0002]

2. Description of the Related Art As a conventional motor mounting structure and a power window regulator, for example, those employed in a power window apparatus shown in FIGS. 11 to 13 are known.

As shown in FIG. 11, a power window device 8 is provided on an inner panel 80 constituting an automobile door.
1 is provided. The power window device 81 includes an X-arm type regulator 82 and a motor 83. The regulator 82 includes a base 84 and the base 8
4 and a sector gear 85 rotatably supported. The regulator 82 opens and closes the window glass by rotating the sector gear 85. A plurality of (only one is shown in FIG. 11) weld bolts 86 are welded and fixed to the base 84 so as to protrude from the base 84.

[0004] The inner panel 80 includes the base 8
A bolt insertion hole 87 that penetrates at each position corresponding to the 4 weld bolts 86 is formed. The weld bolt 86 is inserted into these bolt insertion holes 87. At this time, the tip side of the weld bolt 86 protrudes toward the inside of the inner panel 80 (the lower side in FIG. 11).

A housing 88 of the motor 83 is formed of a resin material, and motor mounting legs 89 are formed on the outer peripheral side thereof at respective positions corresponding to the weld bolts 86 of the base 84. (See FIG. 13). The motor mounting leg 89 has the weld bolt 8
A mounting hole 9 corresponding to 6 and penetrating along its axial direction;
0 is formed. The weld bolts 86 projecting toward the inside of the inner panel 80 are inserted into the mounting holes 90, respectively. A worm (not shown) is provided at the tip of the rotation shaft (armature rotation shaft) of the motor 83. The worm is connected to the housing 88
The worm wheel 91 is rotatably supported in the inside. The worm wheel 91 is connected to an output shaft 94 via a rubber cushion 92 and an iron plate 93.

[0006] The output shaft 94 is provided with a gear 95.
With the motor 83 fixed, the gear 9
5 is arranged to mesh with the teeth of the sector gear 85. That is, the output shaft 94 penetrates the inner panel 80, and is rotatably supported by a bearing hole 84a provided in the base 84 corresponding to the output shaft 94,
The positioning is done. And at this time, the gear 95
Are arranged so as to mesh with the teeth of the sector gear 85.

The motor 83 is fixed to the inner panel 80 together with the regulator 82 by screwing a nut 96 from the tip of the weld bolt 86. In the automobile door configured as described above, when the motor 83 is driven, the sector gear 85 of the regulator 82 is rotated, and the window glass is opened and closed.

[0008]

By the way, in the case of the motor 83 fixed to the inner panel 80 by the screwing of the weld bolt 86 and the nut 96 as described above, the motor mounting leg 89 of the housing 88 has these welds. The fastening force of the bolt 86 and the nut 96 is constantly applied along its axial direction. When such a continuous force is applied to the housing 88 (motor mounting leg 89) formed of a resin material, the motor mounting leg 89 contracts along its axial direction due to a creep phenomenon. . As a result, the weld bolt 86 and the nut 96
Is gradually reduced.

Here, for example, when the window glass is fully closed in the closing operation and the closing operation is sharply restricted, the rotational force of the motor 83 (the output shaft 94) driving the regulator 82 is reduced An attempt is made to rotate the motor 83 as a force. At this time, when the fastening force of the weld bolt 86 and the nut 96 is loose, as shown in FIG.
It rotates within the range of play between the weld bolt 86 and the mounting hole 90. As described above, when the rotation of the motor 83 itself is repeated with the fastening force of the weld bolt 86 and the nut 96 loosened, the nut 9
6 gradually loosens, and eventually the nut 96 comes off, and the motor 83 itself comes off.

In order to prevent a decrease in the fastening force due to the contraction of the motor mounting leg 89 along the axial direction, for example, as shown in FIG.
It has also been proposed to insert a metal collar 97 into the housing. That is, since the collar 97 is made of metal, it does not contract in the above-described axial direction, and the weld bolt 86
Also, the fastening force of the nut 96 is not reduced. However, in this case, there is another problem that the number of parts increases by the amount of the collar 97 and the cost increases.

An object of the present invention is to provide a motor mounting structure that can prevent the motor from falling off without increasing the cost.

A plurality (three) of weld bolts 11a, 11b, 11c are welded and fixed to the base 8 so as to protrude from the base 8.

The motor 7 includes a main body 12 and an output
It is composed of As shown in FIG. 2, the housing 14 of the output portion 13 is formed in a substantially bottomed cylindrical shape with a resin material, and has an axial hole 14a formed in the center of the bottom thereof, and a coaxial hole 14a formed in the bottom. A bearing wall 14b extending inward in the axial direction is formed to avoid this. The housing 14
An extension portion 14c is formed at the bottom of the base member to extend outward in the axial direction, avoiding the coaxial hole 14a. The housing 1
A substantially cylindrical worm case portion 14d communicating with the main body portion 12 is formed in a part of the cylindrical portion 4. Further, as shown in FIG. 5, on the outer peripheral side of the housing 14, the weld bolts 11a to 11a of the base 8 are provided.
Motor mounting leg 1 formed at each position corresponding to 1c
5 are formed. The motor mounting legs 15 are provided with mounting holes 15a, 15b, and 15 that respectively penetrate in the axial direction corresponding to the weld bolts 11a to 11c.
c is formed. As shown in FIG. 6 and FIG. 7, the base 8 (weld bolt 1) of one of the mounting holes 15a to 15c is attached to the mounting hole 15a.
On the side facing 1a), a substantially cylindrical boss 15d protruding along the inner peripheral surface is formed. The opening of the housing 14 is covered with a cover 13a.

A rotating shaft (not shown) of the main body 12 is interposed in the worm case 14d. A worm (not shown) is provided on the rotating shaft. In the housing 14, a worm wheel 16 is rotatably supported on the outer peripheral side of the bearing wall 14b. The worm wheel 16 meshes with the worm of the rotating shaft. In the housing 14, the bearing wall 14b
An output shaft 17 is rotatably supported on the inner peripheral side of the shaft.
In the output shaft 17, a portion of the housing 14 protruding from the extending portion 14c is provided with a gear 20. The worm wheel 16 and the output shaft 17 are connected via a rubber cushion 18 and an iron plate 19. That is, when the rotation shaft of the main body 12 rotates, the worm wheel 16 rotates, and the rotation force is transmitted to the output shaft 17 via the rubber cushion 18 and the iron plate 19, so that the output shaft 17 and the gear 20 rotate. ing.

In the extending portion 14c of the housing 14, an annular elastic ring 21 formed of, for example, a closed-cell foam is fixed to an axially intermediate portion of the outer peripheral surface thereof. The output shaft 1 is provided on the base 8 of the regulator 6.
The bearing hole 8a corresponding to 7 is formed.

The inner panel 5 is provided with a housing recess 5a large enough to house the motor 7 from the inside (inside the room). Bolt insertion holes 22a, 22b, and 22c penetrate at respective positions corresponding to the weld bolts 11a to 11c of the base 8 in the accommodation recess 5a.
Are formed. Note that the bolt insertion hole 22a corresponding to the mounting hole 15a in which the boss 15d is formed has an inner diameter equal to the outer diameter of the boss 15d. And
When the output portion 13 of the motor 7 is attached to the inner panel 5, the boss 15d is fitted into the bolt insertion hole 22a (see FIGS. 1, 2, and 6).

A through hole 5b is formed in the housing recess 5a at a position corresponding to the extension 14c of the housing 14. The through hole 5b is formed to be larger than the outer diameter of the extension 14c and smaller than the outer diameter of the elastic ring 21. The inner panel 5 has a hole 5c for inserting the regulator 6 into a gap between the outer panel 4 and the inner panel 5.

The power window device 3 (the regulator 6 and the motor 7) is mounted on an automobile door as follows. First, the regulator 6 is inserted into the gap between the outer panel 4 and the inner panel 5 from the hole 5c. Then, the weld bolts 11 a to 11 c of the regulator 6 are inserted into the bolt insertion holes 22 a to 22 c of the inner panel 5. At this time, the distal ends of the weld bolts 11a to 11c protrude inward (inside the room) in the accommodation recess 5a of the inner panel 5 (see FIG. 2).

Next, as shown in FIG.
The mounting holes 15a to 15c of the motor 7 are respectively fitted into the welding bolts 11a to 11c protruding from the motor 7 (in the figure, the welding bolts 11b and 11c and the mounting holes 15b and 15c are omitted). At this time, the tip of the output shaft 17 is fitted into the bearing hole 8a of the base 8 to position the output shaft 17, and the gear 20 is fitted and inserted so as to mesh with the teeth of the sector gear 9. The boss 15d is fitted in the bolt insertion hole 22a. In this state, the nut 23 is screwed from the distal end side of the weld bolts 11a to 11c so that the regulator 6
And the motor 7 is fixed to the inner panel 5.

At this time, the extension 14c of the housing 14 penetrates through the through hole 5b of the inner panel 5 and projects into the gap between the outer panel 4 and the inner panel 5. The distal end of the elastic ring 21 fixed to the outer peripheral surface of the extending portion 14c is in contact with the inner panel 5,
The motor 7 is pressed and bent in a direction opposite to the direction in which the motor 7 is mounted, and is compressed and adhered to the inner panel 5 and the housing 14 so as to close the through hole 5b. For this reason, even if, for example, water drops enter through the window glass entrance 1a formed between the outer panel 4 and the inner panel 5, the motor 7 excluding the extension 14c and the gear 20 of the output shaft 17 causes the water drops to enter. Exposure is prevented.

A lower end of a window glass (not shown) is attached to the upper arm 10 of the power window device 3 thus attached. More specifically, the lower end of the window glass is inserted into the same gap from the window glass entrance 1a formed between the outer panel 4 and the inner panel 5, and is fixed to the upper arm 10.

Then, the door trim 2 is fixed inside the inner panel 5 (inside the room). In the vehicle door thus configured, when the motor 7 is driven, the sector gear 9 of the regulator 6 is rotated, and the upper arm 10 is moved up and down. Then, the window glass is moved up and down to perform an opening and closing operation.

As described in detail above, according to the present embodiment, the following effects can be obtained. (1) In the present embodiment, the base 8 (weld bolt 11) of the mounting hole 15a formed in the motor mounting leg 15 is formed.
A boss 15d was formed on the side facing a). On the other hand, the inner diameter of the bolt insertion hole 22a formed in the inner panel 5 was formed to be equal to the outer diameter of the boss 15d. When attaching the regulator 6 and the motor 7 to the inner panel 5, the boss 15d and the bolt insertion hole 22a are fitted, and in this state, the nut 23 is screwed into the weld bolt 11a from the tip end side. The regulator 6 and the motor 7 were fixed to the inner panel 5. At this time, the output shaft 17 was positioned by fitting the tip of the output shaft 17 into the bearing hole 8a of the base 8. Therefore, even if the housing 14 (motor mounting leg 15) contracts along the axial direction due to the creep phenomenon, and the fastening force between the weld bolt 11a and the nut 23 is reduced, the fitting between the boss 15d and the bolt insertion hole 22a is not required. The positioning of the housing 14 (motor 7) can be ensured by the output shaft 17 positioned in the axial direction. Then, for example, when the window glass is fully closed in the closing operation and the closing operation is sharply restricted, the rotational force of the motor 7 (the output shaft 17) driving the regulator 6 becomes a reaction force, and the motor 7 is stopped. Even if it is attempted to rotate, the rotation can be suitably prevented. For this reason, loosening and falling off of the nut 23 can be prevented, and falling off of the motor 7 can be suppressed.

(2) In this embodiment, the boss 15d can be formed at the same time as the original step of forming the housing 14 (motor mounting leg 15). On the other hand, bolt insertion hole 2
2a can also be formed in accordance with the original process of processing the inner panel 5. Therefore, the motor can be prevented from falling off without increasing the manufacturing cost.

(3) In the present embodiment, the boss 15d is formed only on the motor mounting leg 15 in which the mounting hole 15a is formed among the plurality (three) of the motor mounting legs 15. Therefore,
For example, as compared with the case where the same boss is formed on all the motor mounting legs 15, the mounting holes 15a to 15b for the above-described weld bolts 11a to 11c and the bolt insertion holes 22a to 22c are provided.
The tolerance of the positional accuracy of the position 15c can be increased, and the assemblability can be improved.

(4) In this embodiment, the motor 7 and the regulator 6 are fixed to the inner panel 5 by connecting the motor 7 and the regulator 6 with the inner panel 5 interposed therebetween.
And a bolt connecting the power window device 3 including the motor 7 and the power window device 3 to the inner panel 5.
Bolts 11a to 1
1c. Further, the step of connecting the regulator 6 and the motor 7 and the step of fixing the power window device 3 to the inner panel 5 can be the same step. Therefore, the cost of the power window device 3 can be reduced, and the cost of the automobile door including the power window device 3 can be reduced.

(5) In the present embodiment, the inner panel 5
Since the housing 7 is provided with a housing recess 5a large enough to house the motor 7, the motor 7 can be housed in the housing recess 5a. Therefore, even if the motor 7 is disposed on the indoor side of the inner panel 5, the motor 7 does not protrude toward the indoor side. As a result, the vehicle interior can be kept wide with the door trim 2 fixed inside the inner panel 5 (inside the cabin).

(6) In this embodiment, since a large load is applied, the support can be ensured. (7) In the present embodiment, the output shaft 17 supported by the bearing hole 8a of the base 8 can position the output shaft 17 with respect to the inner panel 5 of the motor 7 in the radial direction.

(8) In this embodiment, the output shaft 17 can be positioned in the circumferential direction with respect to the inner panel 5 of the motor 7 by fitting the boss 15d and the bolt insertion hole 22a. Note that the embodiment of the present invention is not limited to the above-described embodiment, and may be modified as follows.

In the above embodiment, the housing recess 5a is provided in the inner panel 5, and the motor 7 is provided in the housing recess 5a.
Are arranged, but the accommodation recess 5a may not be provided. In the above-described embodiment, three motor mounting legs 15 (mounting holes 15a to 15c) are provided.

In the above embodiment, the mounting hole 1
Although the boss 15d is provided on the motor mounting leg 15 in which the 5a is formed, it may be provided on the motor mounting leg 15 in which the mounting hole 15b or 15c is formed. Further, bosses may be provided on the motor mounting legs 15 in which any two of these mounting holes 15a to 15c are formed, or bosses may be provided on all the motor mounting legs 15.

In the above-described embodiment, the boss 15d is formed in a substantially cylindrical shape, and the bolt insertion hole 22a is formed in the inner panel 5 so as to fit the boss 15d. The shape for such fitting is not limited to the above. For example, a boss projecting in a polygonal shape is formed, and a polygonal bolt insertion hole is formed in the inner panel 5 so as to fit in the boss. May be.

As shown in FIG. 8, a boss 31 is formed on the inner panel 5 side in accordance with the position of the bolt insertion hole 22a, and the boss 31 is fitted on the motor mounting leg 15 side so as to fit with the boss 31. A mating hole 32 may be formed. Also in this case, the positioning of the housing 14 (motor 7) can be ensured by the fitting of the boss 31 and the fitting hole 32 and the positioned output shaft 17.

In the above embodiment, the weld bolts 11a to 11a welded to the base 8 of the regulator 6
The motor 7 was fixed to the inner panel 5 by screwing the nut 1c and the nut 23. On the other hand, as shown in FIG.
Weld nut 36 and bolt 3 welded to base 8
7, the motor 7 may be fixed to the inner panel 5.

The motor 7 may be fixed to the inner panel 5 using a tapping screw, for example. In the above embodiment, the boss 15d is connected to the inner panel 5
10, a fitting hole 41 is formed in the base 8, as shown in FIG. 10, for example, while the fixing portion 15 protrudes in correspondence with the fitting hole 41. It is also possible to form a fitting projection 42 to fit the fitting hole 41 and the fitting projection 42.

The fitting hole 41 and the fitting projection 42 may be formed in a substantially rectangular shape extending in the radial direction of the output shaft 17. In particular, the radial length of the fitting hole 41 is set to be longer than the radial length of the fitting projection 42, and the inner of the motor 7 is fitted by fitting the fitting hole 41 and the fitting projection 42. Only the circumferential positioning of the output shaft 17 with respect to the panel 5 is performed,
A required play may be provided in the same radial direction. By providing the play in the radial direction as described above, a mounting error in the radial direction can be absorbed, and the mountability of the motor 7 can be improved.

Incidentally, a similar shape may be applied to the boss 15d and the bolt insertion hole 22a. The fixing mode of the motor 7 adopted in the above embodiment is an example, and for example, the motor 7 may be directly fixed only to the inner panel 5. In short, any structure may be used as long as the output shaft 17 of the motor 7 is positioned and the housing 14 of the motor 7 is mounted on a predetermined panel by the coupling means.

In the above embodiment, the present invention is applied to a power window device, but may be applied to, for example, a sunroof device. Further, another device may be used as long as the output shaft 17 of the motor 7 drives a load and the operation of the load is sharply regulated.
