Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention particularly relates to an opening/closing device for a member to be opened and closed, such as an automobile window or a sunroof. This invention relates to an improvement in a power supply device for a self-propelled switchgear when moving.

[Prior Art] A conventional example of this type of self-propelled power A%'7T and a power window regulator, which has a side of 1" and is contrary to passenger cars, will be explained in detail.

This kind of self-propelled park window regulation...
Fix the drive source to the door side 1. The X-arm method from 6M is an alternative to the wire 1 drive method, and is used for driving (by moving the arm along with the window glass.

This is advantageous in that it greatly reduces the number of parts1 and makes effective use of the door space.

Proposals for this type of self-propelled power window L. This will be partially explained using the configuration of Utility Model Application Publication No. 60-68284 as an example.

The power window disclosed in the same publication is the 17th
In the figure: 1 (glass fixed to the lower end of the window glass 10, the L holder 12,
A motor 14 which is fixed to the motor 14 and capable of forward and reverse rotation, and a bigon gear 18 which is rotationally driven by the motor 14 through a motor 16. , fixed to the interior panel of the door in the vertical direction 4;

Therefore, according to this power window, since the four windows are driven by the rack 20 and the vinyl gear 18, the number of parts is small, and moreover, only the glue 20 is fixed vertically to the door-in panel. Therefore, the space inside the door can be used effectively.

[Problems that the invention is trying to solve] By the way, I have already mentioned the self-propelled power window).
In the evening, the drive source for opening and closing, the drive source for opening and closing, moves between the window crows 10 and 1, which are the members to be opened and closed. , the lead wire for feeding power to this module 14 is also connected to the module 14.
-・Evening 14 You can now move freely inside the door! ,
``l must be eliminated.

Here, in addition to the power window mechanism, there are various other mechanical members inside the door, so the motor 1
If the flexible glue wire, which has a deflection equal to the amount of movement stroke 4, is moved without any restrictions, it may cause failures in the functions of various mechanisms.
1 (Power window does not function due to broken wire [7,
There is a possibility that it will disappear.

(However, until now, there has been no power supply device that can supply power to the movable drive source of this type of self-propelled power window without any problems.And,
This was one of the reasons why the self-propelled switchgear of the type 1) had not yet been put into practical use.

Therefore, the purpose of the present invention is to solve the conventional problem of interference 1°, to minimize the bending of the lead wire even when moving the drive source, and to The purpose of the present invention is to provide a power supply device for a self-propelled opening/closing device that can smoothly move the lead wire in a narrow space such as a 1-ton door without any trouble. .

Means for Solving Problem E] The present invention provides a self-propelled switchgear in which a drive source for driving the opening and closing of a member to be opened and closed moves together with the member to be opened and closed. ...support one end of a lead wire for feeding power to the drive source at one point on an orthogonal line that roughly bisects the loaf, and connect the other end of the lead wire to the drive source; According to the movement of the source, the lead wire is swung from a point i on the orthogonal line to the center L7.

[Function] In the present invention, by moving the drive source and swinging the lead wire accordingly, it is possible to connect the drive source from the fixed end to the drive source at the moving end. It is said that Here, the center of oscillation is the moving stroke of the driving source.
It is a point on the 1σ intersection line that roughly divides the area in half. Therefore, the required minimum length of the lead wire is when the driving λ source is approximately at the center of the moving loaf, while the required maximum length of the lead wire is.

This occurs when the driving sources exist at both ends of the direction of movement.

The difference between the minimum and maximum length t1 of the lead wire is approximately the same as the difference in length between the hypotenuse and other sides of the triangle,
By bending the lead wire at least by this difference, it is possible to prevent problems such as breakage of the lead wire. The amount of deflection of the lead wire in the case of the present invention is, for example, [
Compared to the case where the bending is required for the movement stroke of the drive source, it is extremely short, and this bending part can be easily handled, and the bending part of the lead wire does not get caught on other ams etc. due to the movement of the drive source. It is possible to reliably prevent harmful effects such as storage.

In order to provide this kind of deflection, it is easiest to wind the lead wire in a spiral shape.This increases the rigidity of the lead wire that undergoes oscillating displacement, so it can be used, for example, in automobile power windows. However, the lead wire is less likely to vibrate during running.

In addition, it is difficult to completely prevent vibration by simply making the lead wire spiral, and the noise caused by this can be solved by placing a sound deadening material inside the inner panel of the door, but it is even more preferable. As a countermeasure, a guide shaft can be provided to guide the swinging of the lead wire.

When this guide shaft is swung, the drive source usually moves in a straight line rather than in an arc centered around the oscillation center. The guide shaft may be made to be slidable in a direction perpendicular to this direction, or the guide shaft itself may be made telescopic.

[Example] Hereinafter, an example in which the present invention is applied to a self-propelled power window regulator will be specifically described with reference to the drawings.

The slide support member 100 has a long rectangular shape 10 whose longitudinal direction is perpendicular to the moving direction of the motor 0.
1, and is fitted into this J↓ hole 101 so that the slider 102 can slide in the direction of the arrow in FIG. The first clamper 104 is detachable.

The slider 102 has a narrow portion 102a narrower than the notch width in the fishing rod direction of the long hole 101, and wide portions 102 on both sides of the narrow portion 102a, as shown in FIG.
b and 102c, and by fitting into the elongated hole 101 as shown in FIG. 8, movement is allowed only in the longitudinal direction of the elongated hole 101. In addition, in order to realize the fitting form as shown in FIG.

All you have to do is move 02.

Further, on this slider 102, the guide shaft 90
A drum-shaped rotation support part 103 is provided to rotatably support a hook part 92 formed at one end of the clamp, and a second clamper 105 is detachably attached.

The lead wire 80 taken out from the motor body 61
is first clamped by a first clamper 104 which is attached to the slide support member 100 by elastic deformation as shown in FIG. 16, and then by a second clamper 105 which is attached to the slider 102 by elastic deformation. It is designed to be clamped by. Note that the second clamper 105 slides together with the slider 102, so the second clamper 105 slides together with the slider 102, so the second clamper 105 slides together with the slider 102. The lead wire 80 between the second clampers 104 and 1r) 5 is given an appropriate bend.

Next, the operation of the power window will be explained.

The driving principle of this power window is similar to the conventional rack-binion system proposal, in which the output of the motor body 61 is
While being decelerated by the gear in the gear housing 62,
This is done by transmitting the signal to the pinion gear 50 having a rotating shaft in a direction perpendicular to the output shaft of the motor body 61.

When this driving force is transmitted, the binion gear 50 rotates while meshing with the rack 40, but the rack 40 is fixed to the door inner plate 32 via the bracket 41 and the mounting piece 41a. Because there is, Binyonggi?
The SO rotates and moves along the rack 40.

The pinion gear 50 is connected to the motor 60. Since the supporting member 70 and the window glass 30, which is the member to be opened and closed, are integrally supported, these members move together with the pinion gear 50, and the window glass 30 is opened and closed by the forward and reverse rotation of the motor 60. It becomes possible to move.

In this way, in a self-propelled power window, the motor body 61 is used together with the window glass 30, which is a member to be opened and closed.
will also be moved.

Therefore, a power supply device for supplying power to the moving motor body 61 operates as described below to supply power to the motor body 61.

Connection end side 8 of the lead wire 80 to the motor main body 61
0b is supported by a slide support member 100 formed on the gear housing 62 that moves together with the motor body 61. More specifically, the first and second clampers 104
．． 105 and is clamped with an appropriate deflection.

Here, by driving the motor 60, for example, the window 3
If you move 0 from the bottom, it will be at the bottom of Figure 1.

The motor 60 moves from the state shown by the broken line at the bottom, through the state shown by the solid line at the center position, and then to the state shown by the broken line at the top. At this time, the lead wire 80 is supported by the guide shaft 90 and swings around the pivot piece 85 of the inner panel 201.

In this case, the motor 60 moves linearly along the rack 40 while the guide shaft 90 swings, so in order to ensure this swing, the slider 102 is inserted into the elongated hole of the slide support member 100. 101, thereby making it possible to swing the guide shaft 90.

When the lead wire 80 swings, the length of the spiral portion 81 wound around the guide shaft 90 remains unchanged, and only the sliding bone of the slider 102 causes the lead wire 80 to move.
By flexing, the movement of the motor 60 can be followed.

The amount of deflection at this time can be determined by placing the center of oscillation on the orthogonal line -1- which roughly bisects the moving stroke of the motor taro 0, as shown in Figure 1. The amount of deflection can be set by bending the lead wire 80 between the first and second clampers 104 and 105 for 1 minute. Since the amount of deflection is small, there is extremely little risk that the movement of this part will interfere with other mechanisms, and it is possible to construct a window glass or shutter with fewer failures.

In addition, in this embodiment, the movement stroke of motor 0 is 7.-
・The length of the guide shaft 90 is set to about 400 mm]7, and the movement range of the slider 102 at this time is 40 mm.

The window glass 30 is often approximately trapezoidal as shown in FIG. Preferably, if <, in this way, l increases the length from the swinging fulcrum on the left side of FIG. 1 to the movement trajectory of Mo. :, What is the length of the guide shaft 90? < If the swing angle is the same, the amount of movement of the sweeper can be reduced.

In addition, in the case of the embodiment -1, the spiral shape 81
2. This is for the convenience of being easily supported on the guide shaft 90. Since the part ' is not pulled, for example, it may be supported on the kite shaft 90 by a clamper without being twisted in a spiral shape [2].

<Second Example> This second example includes 1. Is it possible to have a guide shaft that supports the lead wire 80 as in the first embodiment, or to make the guide shaft itself extendable and retractable instead of having this movable end be slidable? '-, Guide shaft and lead wire ＼”8

That is, in this second embodiment, as shown in FIG.

0a and 110b are connected together, around which the helical form 81 of the lead wire 80 is wound with a winding force i.

Note that the fixed end side of the guide shaft 110 is rotatably supported on the inner panel 201 side by the rotation support piece 85 as in the first embodiment)-11, and the movable end side is supported by the gear housing 62. It is rotatably supported by a rotatable piece 86 which is fixed at the part gt1.

Further, both ends of the guide shaft 110 are fixed 1.1, and a bellows member 120 is installed to surround the spiral shape 81.

In this second embodiment, the swing of the guide shaft 110 following the movement of the motor 60 is controlled by the guide shaft 11.
0 itself is expanded/contracted J5. Since the length is 14, there is no need for a slide to allow the moving end side of the guide shaft to slide as in the first embodiment. Also,

is inserted and supported.

The support piece 88 fixed to the gear housing 62 also has the same structure as the support piece 87 shown in FIG.

As shown in FIG. 15, the lead wire 8 is attached to the drum part 88a.
The lead wire 80 is wound around the movable end side of the lead wire 80, and is supported by inserting the lead wire 80 into a hole 88c formed in the side surface 88b.

Even with such a simple configuration, when the window regulator is driven as shown in FIG. 12, the lead wire 80 can be swung by the expansion and contraction of the lead wire 80 itself.

At this time, by selecting a predetermined material for the lead wire 80, the rigidity of the helical form 81 can be increased, or a sensor output line, etc. for realizing other additional functions of motor drive can be connected in a helical form. By forming the lead wire 80, the rigidity can be increased, and by devising in this way, the vibration of the lead wire 80 when the vehicle is running can be reduced, and the generation of abnormal noise can be reduced. In addition, door panel 201.2
02 may be formed with a sound deadening material.

In each of the above-mentioned embodiments, when viewed from the moving end side of the window glass 30, the output shaft of the motor body 61 (coincident with the center line P) is arranged so as to coincide with the center line of the window glass 30 in the thickness direction. It is configured. Therefore, the center line of the window glass 30 (i.e., the center line P
) to the center line of the rack-binion (line R shown in FIGS. 3 and 4) that generates the driving force that drives the window glass 30 in the vertical direction, compared to the conventional rack-binion.
It is much shorter than the pinion method.

As a result, the rotational moment acting on the window glass 30 in proportion to the distance is significantly smaller than before, and the frictional force with the window frame that occurs when opening and closing can be reduced.
By arranging the motor 60 which has conventionally low torque, there is also the effect that efficient and reliable opening/closing operations can be ensured.

Note that the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention.

For example, vehicle doors are generally curved, and the motor 60
The movement path of the robot is also curved as shown in FIG. Therefore, the rotation support points at both ends of the guide shafts 90 and 110 have a degree of freedom in the thickness direction of the door.
It is preferable that the drum portion around which the hook portions at both ends of the guide shaft are wound has a shape with a sufficient width in the door thickness direction, or that a universal joint or the like is used.

Note that the present invention is not necessarily applied to power windows, but can be applied to devices in various fields that drive opening and closing members to be opened and closed.

For example, in the case of automobiles, it can also be used as a power supply device for driving sunroofs to open and close, which has been a problem in recent years.

[Effects of the Invention] As explained below, according to the present invention, in a self-propelled switchgear in which the drive source moves together with the member to be opened and closed, the lead wire that supplies power to the moving drive source is connected to the drive source. It is possible to provide a power supply device that can be smoothly swung to follow the movement of the power supply device, and can reliably prevent problems such as wire breakage due to getting caught in surrounding mechanisms.
