Description

[Detailed description of the invention] This invention is an automobile in which the window opening/closing handle attached to the inside surface of the door of an existing automobile is removed, and a window motor is connected to the mounting shaft to open/close the window by power. This invention relates to improvements to window opening/closing devices.

Conventionally, as shown in FIG. 1, this type of device has a case 8 that houses a window motor 1, which is composed of an upper case 8a and a lower case 8b to which the motor 1 is fixed. A base (not shown) is fixed to the inner panel 11 attached to the inner panel 12, and the hollow output shaft 6 of the wind motor 1 is fixed to the inner panel 12.
A type is known in which the output shaft 6 is connected to the mounting shaft 15 through a connector 16 that faces the mounting shaft 15 provided on the mounting shaft 15 and engages with the output shaft 6 and the mounting shaft 15, respectively. The connector 16 is formed into a cylindrical body that is inserted into the hollow output shaft 6, and the output shaft 6 is attached to the outer periphery of the connector 16.
An engagement protrusion 16 that engages with an engagement groove 6a' provided in the
a' and a spline groove 16b that engages with a spline 15b provided on the mounting shaft 15 on its inner periphery to transmit the rotational force of the output shaft 6 to the mounting shaft 15 via the connector 16. . However, mounting shaft 1
The amount of protrusion from the inner panel 11 varies depending on the vehicle model, and in models with a small amount of protrusion, the inner panel 11 may move away from the inner panel 12 due to the weight of the window motor 1 and case 8 when the door is strongly closed. As a result, the wind motor 1 also moves in the same direction and the mounting shaft 15
In some cases, the connector 16 was disengaged from the output shaft 6, or the output shaft 6 and the connector 16 were disengaged from each other. Furthermore, if eccentricity occurs between the output shaft 6 and the mounting shaft 15, it will cause abnormal noise and reduce transmission efficiency, so a play H is provided between the inner circumference 6b of the output shaft 6 and the connector 16 to prevent eccentricity However, due to this play H, the weight of the wind motor 1 and the case 8 cannot be received by the mounting shaft 15 via the connector 16, and all this weight is absorbed by the inner lining 11. It will be received at the fixed part. Many of the inner linings 11 have a fragile structure mainly made of cardboard, and have the disadvantage that the fixed portions of the inner linings 11 are damaged and the case 8 falls off due to the impact when the door is closed.

Also, as shown in FIG. 2, a spring pin 1 connects a window opening/closing handle (not shown) to a mounting shaft 15.
7 to prevent the connector 16 from coming off in the axial direction with respect to the mounting shaft 15, and the inner circumference 6 of the output shaft 6.
A plurality of claws 20 extending in the axial direction at appropriate intervals are provided on the outer periphery of the connector 16 that fits into the connector 16, and the side surface of the dish-shaped washer 21 is brought into contact with the vicinity of the tips of the plurality of claws 20. It is also known that the connector 16 is fixed to the output shaft 6 by tightening the screw 22 to spread the tips of the claws 20 in the radial direction. In the case of this method, even when the door is strongly closed, the inner lining 11 will not float, so the connector 16 and the mounting shaft 15 or the output shaft 6 will not come out of engagement, but the output shaft 6 and the mounting shaft 15 The eccentricity of the output shaft 6 cannot be absorbed, and there are disadvantages in that abnormal noise is generated with each rotation of the output shaft 6 and the transmission efficiency is reduced.

The present invention solves the above-mentioned conventional drawbacks, and provides an automobile window opening/closing method that does not cause damage to the connecting part of the inner lining to the case, does not cause the case to fall off, and does not cause abnormal noise or decrease in transmission efficiency. The purpose of this device is to provide a device in which a case containing a window motor is fixed to the inner lining of a car door, and the case is inserted into the hollow output shaft of the window motor to connect the output shaft and the window opening/closing handle. In an automobile window opening/closing device in which an output shaft is connected to a mounting shaft through connectors that engage with the mounting shafts, the connectors are engaged with the mounting shaft by being prevented from coming off in the axial direction by a retaining member. and the connector is loosely fitted onto the inner periphery of the output shaft, and an engagement protrusion provided on the connector is engageable with an engagement groove provided on the inner periphery of the output shaft; A small diameter shaft protruding in the axial direction is provided at the end opposite to the mounting shaft, and a stepped portion is formed on the inner peripheral edge of the output shaft opposite to the mounting shaft, and a push nut is press-fitted into the small diameter shaft, and the back surface of the push nut is This is achieved by using an automobile window opening/closing device that is pressed against the stepped surface of the stepped portion.

An embodiment of the automobile window opening/closing device according to the present invention will be described below with reference to FIG.

1 is a window motor, and the motor 1 has a worm 2 formed at the tip of an armature shaft (not shown).
, a reduction gear 3 that meshes with the worm 2, and a reduction gear 3 that is rotatably supported by the gear case 4.
It has a hollow output shaft 6 to which rotation of is transmitted via a buffer member 5. The output shaft 6 has a washer 7,
7 to fix it in the axial direction to the gear case 4. In this embodiment, the buffer member 5 is fixed to the outer peripheral surface of the output shaft 6. Reference numeral 8 denotes a case that houses the window motor 1, and an upper case 8a.
and a lower case 8b to which the motor 1 is fixed with screws 9. Upper case 8a and lower case 8b are fixed with screws 10. 11 is a lining attached to an inner panel 12 of an automobile door.

The case 8 is fixed to the inner lining 11 by a bolt 13a that is inserted between the inner panel 12 and the inner lining 11 through the inner lining 11 and into the lower case 8b.
At least two caul plates 13 having a
4 by screwing them together. Reference numeral 15 denotes a mounting shaft for a window opening/closing handle rotatably provided on a base (not shown) of a window regulator fixed to the inner panel 12, and the mounting shaft 15 is fixed in the axial direction. This mounting shaft 15 includes the inner panel 12, lining 11 and lower case 8b.
It penetrates through holes 12a, 11a, and 8c, respectively, and protrudes into the vehicle interior, facing the output shaft 6. By rotating the mounting shaft 15, a link mechanism (not shown) attached to the window glass can be driven to raise and lower the window glass.

16 is a connector that engages with the output shaft 6 and the mounting shaft 15, respectively, and connects them. This connector 16
is formed into a cylindrical body to be inserted into the hollow output shaft 6, and can be engaged with an engagement groove 6a provided on the outer periphery of the connector 16 on the inner periphery 6b of the output shaft 6, thereby preventing rotation of the output shaft 6. An engaging protrusion 16a for transmitting force is provided, and a spline groove 16b is provided on the inner periphery of the engaging protrusion 16a to engage with a spline 15b provided at the tip of the mounting shaft 15. and is transmitted to the mounting shaft 15. Here, output shaft 6 and mounting shaft 1
In order to absorb the eccentricity between 5 and 5, the inner circumference 6 of the output shaft 6
b and the outer periphery 16d of the connector 16 and the engagement groove 6
A play is provided between each of the engagement protrusions 16a and 16a.
In other words, the connector 16 is loosely fitted onto the inner circumference 6b of the output shaft 6. If the tip of the mounting shaft 15 is, for example, a serration, the inner circumference of the connector 16 may be a serration groove, that is, the inner circumference of the connector 16 has a shape that engages with the shape of the tip of the attachment shaft 15. It's fine.

The connector 16 is prevented from coming off in the axial direction with respect to the mounting shaft 15 using a spring pin 17 that serves as a retaining member, but this spring pin 17 is used as a window opening/closing handle for manual operation on the mounting shaft 15 in existing automobiles. If a spring pin (not shown) is used to connect the parts, the parts can be used effectively. Also connector 1
6 is integrally provided with a small diameter shaft 16c protruding in the axial direction at the end opposite to the mounting shaft 15, and a stepped portion 6c is provided on the inner peripheral edge of the output shaft 6 on the opposite side to the mounting shaft 15.
, and the push nut 18 is connected to the small diameter shaft 1.
6c, and press the back surface of the push nut 18 against the stepped surface 6d of the stepped portion 6c via the washer 19. Therefore, the weight of the wind motor 1 and the case 8 can be supported by the mounting shaft 15 via the output shaft 6, the washer 19, the push nut 18, the small diameter shaft 16c, and the connector 16, and the weight is absorbed by the lower case 8b and the inner lining. 11 will not be affected. Therefore, even if the lining 11 has a fragile structure, it is possible to prevent the fastening portion of the lining 11 from being damaged or the case 8 to fall off due to the impact when the door is closed. Further, since the play described above absorbs the eccentricity between the output shaft 6 and the mounting shaft 15, no abnormal noise is generated every time the output shaft 6 rotates, and no reduction in transmission efficiency occurs. Further, an output shaft 6 is connected to a mounting shaft 15 fixed in the axial direction via a connector 16.
is fixed in the axial direction, so even if a force is applied to the lining 11 in the direction away from the inner panel 12 due to the weight of the window motor 1 and case 8 when the door is strongly closed, the output shaft 6 will not move and the connection will be maintained. Child 1
6 and the mounting shaft 15 or the connector 16 and the output shaft 6 never come out of engagement.

The outer diameter and inner diameter of the washer 19 are determined so that the outer circumferential surface of the washer 19 does not interfere with the inner circumferential surface of the stepped portion 6c even if the output shaft 6 and the mounting shaft 15 are eccentric.
Further, the washer 19 may be omitted; in that case, a push nut 18 having a shape such that the back surface of the push nut 18 comes into contact with the stepped surface 6d may be used.

Next, the installation order of this device will be explained.

First, an insertion hole 11b is formed in the inner lining 11 facing each of the insertion holes 8d drilled at a plurality of locations in the lower case 8b.
Each patch plate 13 with a bolt 13a implanted therein is placed on the back of the lining 11 removed from the inner panel 12, and the bolt 13a is inserted into the insertion hole 11.
b, 8d and temporarily tighten with nuts 14. Thereafter, the inner lining 11 is attached to the inner panel 12, and the spline groove 16b provided on the inner circumference of the connector 16 is engaged with the spline 15b provided at the tip of the mounting shaft 15, and the spring pin 17 is used to engage the spline groove 16b provided on the inner circumference of the connector 16. 16 is prevented from coming off in the axial direction with respect to the mounting shaft 15. After that, the hollow output shaft 6 is inserted into the connector 16, and the wind motor 1 is fixed to the lower case 8b with screws 9.
The lower case 8b is positioned relative to the inner lining 11 so that the mounting shaft 15 and the mounting shaft 15 are arranged on substantially the same axis, and the nut 14 is used to finally fasten the two. At this time, even if some eccentricity occurs, this eccentricity is absorbed because play is provided between the output shaft 6 and the connector 16. Next, a washer 19 is inserted into the small diameter shaft 16c provided at one end of the connector 16, and a push nut 18 is press-fitted into the shaft 16c, and the back surface of the push nut 18 is pushed onto the stepped surface 6d of the output shaft 6 via the washer 19. guess. Finally, the upper case 8a is fixed to the lower case 8b using screws 10 to complete the assembly.

In this way, according to the present invention, even though play is provided between the output shaft and the connector to absorb the eccentricity between the output shaft and the mounting shaft, all the weight of the wind motor and the case is supported by the mounting shaft. This makes it possible to prevent damage to the fastening part of the inner lining with the case or to prevent the case from falling off, and also to prevent the play from causing abnormal noise or reducing transmission efficiency with each rotation of the output shaft. can be prevented.
Furthermore, since the output shaft is fixed in the axial direction of the mounting shaft via the push nut and the connector, the output shaft will not move and the connector will not move even if force is applied to the lining in the direction away from the inner panel when the door is strongly closed. This has excellent effects such as being able to prevent the attachment shaft or connector from disengaging from the output shaft.
