Description

Wire drive device and window glass lifting device

The present invention relates to a wire drive device and a window glass elevating device.

Conventionally, window glass elevating devices used in automobiles have been known. (See, for example, Prior Document 1). The window glass elevating device includes a wire driving device that winds in and unwinds the wire required for the elevating operation of the window glass. The wire drive includes a wire, a wire drum around which the wire is wound, and a drum housing that rotatably houses the wire drum.

Such a wire drive device is provided with a drum accommodating wall portion that forms a drum accommodating space in the drum housing. The drum accommodating wall portion is arranged so that the inner peripheral surface thereof and the outer peripheral surface of the wire drum form a slight gap, and guides and regulates the wires to be wound and unwound by the rotation of the wire drum. The reason for doing this is that when the tension of the wire is loosened, the wire tends to float due to its own rigidity, and it is difficult to achieve good winding and unwinding even if the wire drum simply rotates.

By the way, in the process of assembling the wire drive device, there is a process of accommodating the wire drum in the drum accommodating space of the drum housing. However, since the wire is wound around the wire drum, the wire may be lifted and caught on the drum accommodating wall when the wire drum is accommodated. In that case, it is necessary for the operator to accommodate the wire drum while pulling the wire or pressing the wire, which causes a deterioration in productivity. Therefore, an object of the present invention is to provide a wire driving device in which a free portion of the wire wound around the wire drum when accommodating the wire drum does not get caught in the drum accommodating wall portion.

The technical idea of the present invention can be applied to a wire driving device for winding and unwinding a wire.

First, the window glass elevating device 3 will be briefly described with reference to FIG.

The window glass elevating device 3 realizes the elevating operation of the window glass 2 provided on the side door 1. The window glass elevating device 3 includes a guide rail 4, a carrier plate 5, and a wire driving device 6.

The guide rail 4 supports the carrier plate 5. The guide rail 4 is provided with a bracket 41 in the middle portion thereof, and is fixed to the panel portion 11 constituting the side door 1 by the bracket 41. A wire pulley 42 for guiding the first wire 7 is fixed to the upper end portion of the guide rail 4, and a wire guide 43 for guiding the second wire 7 is fixed to the lower end portion of the guide rail 4. Has been done.

The carrier plate 5 supports the window glass 2. A hook member 51 is attached to the central portion of the carrier plate 5, and the rail portion 44 of the guide rail 4 is sandwiched by the hook member 51 so that the carrier plate 5 can move along the rail portion 44 to the rail portion 44. It is loosely fitted. A wire end locking portion 52 for locking the first wire 7 is formed at the upper end portion of the carrier plate 5, and a second wire 7 is locked at the lower end portion of the carrier plate 5. A wire end locking portion 53 is formed.

The wire drive device 6 winds in and unwinds the first wire 7 and the second wire 7. In the wire driving device 6, a bracket 91 is attached to a drum housing 9 accommodating a wire drum 8, and the bracket 91 is fixed to a panel portion 11 constituting the side door 1. A wire end locking portion 82 (see FIG. 2) for locking the first wire 7 is formed on one side portion of the wire drum 8, and a second wire drum 8 is formed on the other side portion of the wire drum 8. A wire end locking portion 83 (see FIG. 3) for locking the wire 7 of the above is formed.

With such a configuration, when the wire drum 8 rotates to wind the first wire 7 and unwind the second wire 7, the carrier plate 5 rises along the guide rail 4. In this way, the window glass 2 supported by the carrier plate 5 rises (see the arrow U in FIG. 1). On the contrary, when the wire drum 8 rotates to feed out the first wire 7 and wind the second wire 7, the carrier plate 5 descends along the guide rail 4. In this way, the window glass 2 supported by the carrier plate 5 descends (see arrow D in FIG. 1).

Next, the wire drive device 6 will be described in detail with reference to FIGS. 2 to 4.

In FIG. 2, the wire driving device 6 winds in and unwinds the wire 7 required for the raising / lowering operation of the window glass 2 (see FIG. 1). The wire driving device 6 includes a wire 7, a wire drum 8, and a drum housing 9.

The wire 7 is a flexible long body. Here, the first wire 7 connecting the carrier plate 5 and the wire driving device 6 via the wire pulley 42 (see FIG. 1) which is a direction changing member is defined as “raising wire 7A”. Further, the second wire 7 connecting the carrier plate 5 and the wire driving device 6 via the wire guide 43 (see FIG. 1) which is a direction changing member is defined as “lowering wire 7B”.

The ascending wire 7A and the descending wire 7B are wound around the wire drum 8.
As shown in FIG. 3, the wire drum 8 has a substantially cylindrical shape, and a spiral groove 84 is formed on the outer peripheral surface 8s thereof. Therefore, when the wire drum 8 is rotated in one direction by the electric motor 10 (see FIG. 2), the ascending wire 7A is further wound along the spiral groove 84, and the descending wire 7B is unwound from the spiral groove 84. .. On the contrary, when the wire drum 8 is rotated in the other direction by the electric motor 10, the descending wire 7B is further wound along the spiral groove 84, and the ascending wire 7A is unwound from the spiral groove 84.

In FIG. 4, in the drum housing 9, a drum accommodating space 92 having a substantially cylindrical shape for accommodating the wire drum 8 rotatably is formed by a drum accommodating wall portion 93. The drum accommodating wall portion 93 is arranged so that the inner peripheral surface 93s and the outer peripheral surface 8s of the wire drum 8 have a slight gap d (gap d <diameter φ of the ascending wire 7A and the descending wire 7B). There is. Therefore, when the ascending wire 7A is wound around the wire drum 8, the ascending wire 7A is fed along the inner peripheral surface 93s of the drum accommodating wall portion 93 and continuously fits in the spiral groove 84 (see FIG. 3). I will go. Further, when the descending wire 7B is wound around the wire drum 8, the descending wire 7B is sent along the inner peripheral surface 93s of the drum accommodating wall portion 93 and is continuously accommodated in the spiral groove 84.

By the way, when rotating some kind of cylinder and winding some long body, the long body is always stretched in the tangential direction of the cylinder. Therefore, in the drum housing 9 of the wire driving device 6, the wire passage 94 is connected in the tangential direction to the drum accommodating space 92, and the ascending wire 7A stretched in the tangential direction of the wire drum 8 is the wire passage 94. Designed to pass through. Further, the wire passage 95 is connected to the drum accommodating space 92 in the tangential direction, and the descending wire 7B stretched in the tangential direction of the wire drum 8 is designed to pass through the wire passage 95. In the drum housing 9, the drum accommodating space 92 and the two

wire passages

94 and 95 are connected by one outlet portion 96, which will be described later.

With such a configuration, when the wire drum 8 is rotated in one direction by the electric motor 10, the ascending wire 7A can be wound in and the descending wire 7B can be unwound at the same time. At this time, the ascending wire 7A is sent into the drum accommodating space 92 through the wire passage 94 (see arrow F1 in FIG. 2), and the descending wire 7B is sent out of the drum accommodating space 92 through the wire passage 95. Sent (see arrow F2 in FIG. 2). On the contrary, when the wire drum 8 is rotated in the other direction by the electric motor 10, the lowering wire 7B can be wound in and the ascending wire 7A can be unwound at the same time. At this time, the descending wire 7B is sent into the drum accommodating space 92 through the wire passage 95 (see arrow R2 in FIG. 2), and the ascending wire 7A is sent out of the drum accommodating space 92 through the wire passage 94. Sent (see arrow R1 in FIG. 2).

Next, the feature points of the drum housing 9 according to the first embodiment and their effects will be described with reference to FIGS. 5 and 6.

As shown in FIG. 5, in the drum housing 9 according to the first embodiment, the drum accommodating wall portion 93 is the ascending wire 7A or descending from the wire drum 8 accommodated in the drum accommodating space 92 to the outside of the drum housing 9. It has a lead-out port 96 for leading out the wire 7B. Further, the drum accommodating wall portion 93 has an accommodating opening portion 97 forming an opening for accommodating the wire drum 8 in the drum accommodating space 92.

Further, in the drum housing 9, the introduction surface 98 is formed in the accommodating opening 97 of the drum accommodating wall portion 93. The introduction surface 98 has a shape obtained by rotating an inclined straight line in the axial cross section of the drum accommodating wall portion 93 as a bus L and rotating the gene L around the central axis C of the wire drum 8. Therefore, the entrance portion of the drum accommodating space 92 has a tapered shape that gradually expands toward the outside (see the cross-sectional view taken along the line XX in FIG. 5).

Explaining the shape of the introduction surface 98 in detail, when the intersection point of the tip surface 93t on the axial direction side of the drum accommodation wall portion 93 and the introduction surface 98 is “intersection point p1”, the intersection point is from the inner peripheral surface 93s of the drum accommodation wall portion 93. The distance Dr to p1 is designed to satisfy the following mathematical formula M1. That is, the distance Dr is equal to or larger than the diameter φ of the ascending wire 7A and the descending wire 7B.
Formula M1: Dr ≧ φ

This is because, for example, as shown in FIG. 6, when the wire drum 8 is accommodated in the drum accommodating space 92, the tensions of the ascending wire 7A and the descending wire 7B wound around the wire drum 8 are loosened. Even if these

wires

7A and 7B are lifted from the outer peripheral surface 8s of the wire drum 8 (see the marked portion in FIG. 6A), the free portion from the wire drum 8 is the accommodation port portion of the drum accommodating wall portion 93. This is to prevent being caught in 97.

Further, as shown in FIG. 5, the shape of the introduction surface 98 will be described in detail. When the intersection of the inner peripheral surface 93s of the drum accommodating wall portion 93 and the introduction surface 98 is set to “intersection point p2”, the drum accommodating wall portion 93 The distance Da from the tip surface 93t to the intersection p2 is designed to satisfy the following mathematical formula M2. That is, the distance Da is larger than the distance Dr from the inner peripheral surface 93s of the drum accommodating wall portion 93 to the intersection p1 described above.
Formula M2: Da> Dr

wires

7A and 7B are lifted from the outer peripheral surface 8s of the wire drum 8, the free portion from the wire drum 8 can be gradually pressed along the introduction surface 98 to easily accommodate the wire drum 8. (See arrow E in (B) of FIG. 6).

Regarding this point, the introduction surface 98 has a generatrix having a curve gently bulging toward the inner peripheral side, and the generatrix is rotated around the central axis C (see the two-dot chain line V in the enlarged view of FIG. 5). ) Is preferable. In this case, the free portion of the ascending wire 7A or the descending wire 7B can be guided so as to gradually approach the outer peripheral surface 8s of the wire drum 8 along the introduction surface 98, and the wire drum 8 can be more easily accommodated in the drum. It can be accommodated in the space 92. Even in this case, it is assumed that the above-mentioned mathematical formulas M1 and M2 are satisfied.

As described above, the accommodation port 97 of the drum accommodating wall portion 93 is the wire of the wires 7 (raising wire 7A, descending wire 7B) wound around the wire drum 8 when accommodating the wire drum 8. An introduction surface 98 is formed to guide the free portion from the drum 8 into the drum accommodating space 92. According to the wire driving device 6, when the wire drum 8 is accommodated in the drum accommodating space 92, the wire drum 8 among the wires 7 (raising wire 7A and descending wire 7B) wound around the wire drum 8 is used. It is possible to prevent the free portion of the drum from being caught on the drum accommodating wall portion 93. Further, the wire 7 (the ascending wire 7A and the descending wire 7B) can be gradually pressed and guided into the drum accommodating space 92. As a result, the wire drum 8 can be easily accommodated, and as a result, productivity can be improved.

Here, with reference to FIG. 7, the detailed structure of the first drum housing 9 to which other technical ideas are applied will be described.

In the drum housing 9, the introduction surface 98 formed in the accommodating opening 97 of the drum accommodating wall 93 is formed so that the introduction surface 98 is limited to a part of the region. In the drum housing 9, two introduction surfaces 98 are formed.

The first introduction surface 98 is obtained by rotating an inclined straight line in the axial cross section of the drum accommodating wall portion 93 as a bus L1 and rotating the bus L1 about a parallel axis C1 parallel to the central axis C. It has a shape. At this time, the parallel axis C1 is closer to the first introduction surface 98 than the central axis C. The first introduction surface 98 is provided between the outlet side portions 93S / 93S provided on both sides of the outlet portion 96 and one side and the other side of the outlet side portions 93S / 93S. It is formed in the intermediate portion 93C and the outlet side portion 93S on one side of the intermediate portion 93C.

The second introduction surface 98 is obtained by rotating an inclined straight line in the axial cross section of the drum accommodating wall portion 93 as a bus L2 and rotating the bus L2 about a parallel axis C2 parallel to the central axis C. It has a shape. At this time, the parallel axis C2 is closer to the second introduction surface 98 than the central axis C. The second introduction surface 98 is provided between the outlet side portions 93S / 93S provided on both sides of the outlet portion 96 and one side and the other side of the outlet side portions 93S / 93S. It is formed in the intermediate portion 93C and the outlet side portion 93S on the other side of the intermediate portion 93C.

As described above, the reason why the introduction surface 98 is provided on the outlet side portion 93S of the drum accommodating wall portion 93 is that the ascending wire 7A and the descending wire 7B are easily lifted from the outer peripheral surface 8s of the wire drum 8 in such a region. be. For example, in the ascending wire 7A wound around the wire drum 8, a portion extending in the tangential direction is constrained by the wire passage 94, so that when the tension of the ascending wire 7A is relaxed, the ascending wire is released from the outlet portion 96. It is easy to lift up at the outlet side portion 93S, which is the winding direction side of 7A.

In addition, the introduction surfaces 98 and 98 are provided on the

outlet side portions

93S and 93S on both sides of the outlet portion 96, respectively, because the wire drum 8 is provided in the upside down direction with respect to the drum accommodating space 92 of the drum housing 9. This is because the same wire drive device 6 can be used for the side door 1 (see FIG. 1) on the opposite side of the vehicle body by accommodating the above. That is, the wire drive device 6 of the window glass elevating device 3 used for the side door 1 on the right side of the vehicle body and the wire drive device 6 of the window glass elevating device 3 used for the side door 1 on the left side of the vehicle body are shared (with the left and right side doors 1). Because you can use the same one).

As described above, the drum accommodating wall portion 93 is between the outlet side portions 93S / 93S provided on both sides of the outlet portion 96 and one side and the other side of the outlet side portions 93S / 93S. It has an intermediate portion 93C provided. The introduction surface 98 is formed on at least one side of the outlet side portion 93S. According to the wire driving device 6, when the tension of the wire 7 (raising wire 7A / lowering wire 7B) wound around the wire drum 8 is relaxed, the wire 7 (raising wire 7A / lowering wire 7B) It is possible to prevent the free portion from the wire drum 8 from being caught on the drum accommodating wall portion 93. Further, the wires 7 (7A and 7B) can be gradually pressed and guided into the drum accommodating space 92. As a result, the wire drum 8 can be easily accommodated, and as a result, productivity can be improved.

Next, with reference to FIG. 8, the detailed structure of the second drum housing 9 to which other technical ideas are applied will be described.

In the drum housing 9, the introduction surface 98 formed in the storage port portion 97 of the drum storage wall portion 93 is formed in the same manner as the drum housing 9 according to the first embodiment described above. On top of that, a plurality of protrusions 90 are formed in the accommodating opening 97 of the drum accommodating wall 93.

The radial inner tip surface 90s of each protrusion 90 is formed continuously with the inner peripheral surface 93s of the drum accommodating wall portion 93, and the tip surface 90s and the outer peripheral surface 8s of the wire drum 8 are formed. It is formed so as to have a slight gap d (see FIG. 4. Gap d <diameter φ of the ascending wire 7A and the descending wire 7B).
The protruding portion 90 extends inward in the radial direction so as to extend the tip surface 93t on the axial side of the drum accommodating wall portion 93.

This is because after the wire drum 8 is accommodated in the drum accommodating space 92, the tension of the wires 7 (raising wire 7A and descending wire 7B) wound around the wire drum 8 is loosened, and these wires are used. Even if 7 (raising wire 7A, lowering wire 7B) is lifted from the outer peripheral surface 8s of the wire drum 8, the free portion from the wire drum 8 is released from the drum accommodating space 92 along the introduction surface 98. This is to prevent. In other words, the raised portion of these wires 7 (raising wire 7A, lowering wire 7B) is pressed by the tip surface 90S of the protruding portion 90 continuous with the inner peripheral surface 93s, and is drummed along the introduction surface 98. This is because it can be prevented from unraveling from the accommodation space 92.

As described above, the wire 7 (raising wire 7A, lowering wire 7B) wound around the wire drum 8 moves to the outside from the opening of the drum accommodating space 92 in the accommodating port 97 of the drum accommodating wall portion 93. A protruding portion 90 is formed to prevent this from happening. According to the wire driving device 6, even if the tension of the wire 7 (raising wire 7A, lowering wire 7B) wound around the wire drum 8 after accommodating the wire drum 8 is loosened, the wire 7 (raising wire 7A. It is possible to prevent the free portion of the descending wire 7B) from the wire drum 8 from unraveling from the drum accommodating space 92. As a result, it is possible to prevent the wire 7 (raising wire 7A, lowering wire 7B) from being entangled.

Next, the feature points of the drum housing 9 according to the second embodiment and their effects will be described with reference to FIGS. 9 and 10.

As shown in FIG. 9, also in the drum housing 9 according to the second embodiment, the introduction surface 98 is formed in the storage port portion 97 of the drum storage wall portion 93. The introduction surface 98 is formed in the same manner as the drum housing 9 according to the first embodiment.

On top of that, in the drum housing 9 according to the second embodiment, a plurality of restraining portions 99 are formed in the accommodating opening portion 97 of the drum accommodating wall portion 93. Each restraining portion 99 has a slight gap d between the tip surface 99s on the inner side in the radial direction and the outer peripheral surface 8s of the wire drum 8 (see FIG. 4. Gap d <diameter φ of the ascending wire 7A and the descending wire 7B). It is formed so as to be. The restraining portion 99 extends inward in the radial direction so as to extend the tip surface 93t on the axial side of the drum accommodating wall portion 93. Therefore, the introduction surface 98 of the drum accommodating wall portion 93 has a shape in which only the portion where the restraining portion 99 is formed is curved (see the XX cross-sectional view of FIG. 9).

This is because, for example, as shown in FIG. 10, after the wire drum 8 is accommodated in the drum accommodating space 92, the tensions of the ascending wire 7A and the descending wire 7B wound around the wire drum 8 are loosened. Even if these wires 7 (raising wire 7A and lowering wire 7B) are lifted from the outer peripheral surface 8s of the wire drum 8, the free portion from the wire drum 8 is formed from the drum accommodating space 92 along the introduction surface 98. This is to prevent it from unraveling. In other words, since the raised portion of these wires 7 (raising wire 7A and lowering wire 7B) is caught by the restraining portion 99, it is possible to prevent the wires 7 from being unwound from the drum accommodating space 92 along the introduction surface 98. (See arrow G in (B) of FIG. 10).

As described above, in the accommodation port 97 of the drum accommodating wall portion 93, the wire 7 (raising wire 7A, descending wire 7B) wound around the wire drum 8 extends from the opening of the drum accommodating space 92 to the outside. A suppression unit 99 that suppresses movement is formed. According to the wire driving device 6, even if the tension of the wire 7 (raising wire 7A, lowering wire 7B) wound around the wire drum 8 after accommodating the wire drum 8 is loosened, the wire 7 (raising wire 7A. It is possible to prevent the free portion of the descending wire 7B) from the wire drum 8 from unraveling from the drum accommodating space 92. As a result, it is possible to prevent the wire 7 (raising wire 7A, lowering wire 7B) from being entangled.

Here, with reference to FIG. 11, the detailed structure of the third drum housing 9 to which other technical ideas are applied will be described.

In the drum housing 9, the restraining portion 99 formed in the accommodating opening portion 97 of the drum accommodating wall portion 93 is formed only in a partial region. In the drum housing 9, two restraining portions 99 are formed.

The first suppressing portion 99 is formed at a position adjacent to one side of the outlet portion 96. The first restraining portion 99 extends inward in the radial direction so as to extend the tip surface 93t (see FIG. 9) on the axial side of the drum accommodating wall portion 93. Therefore, the introduction surface 98 of the drum accommodating wall portion 93 has a shape in which only the portion where the restraining portion 99 is formed is curved. However, it is also possible that the portion of the drum accommodating wall portion 93 excluding the accommodating opening portion 97 is expanded in diameter at a position adjacent to one side of the outlet portion 96, whereby the restraining portion 99 is formed (FIG. 11). (See the alternate long and short dash line in the YY cross section).

The second suppressing portion 99 is formed at a position adjacent to the other side of the outlet portion 96. The second restraining portion 99 extends inward in the radial direction so as to extend the tip surface 93t on the axial side of the drum accommodating wall portion 93. Therefore, the introduction surface 98 of the drum accommodating wall portion 93 has a shape in which only the portion where the restraining portion 99 is formed is curved. However, it is also possible that the portion of the drum accommodating wall portion 93 excluding the accommodating opening portion 97 is expanded in diameter at a position adjacent to the other side of the outlet portion 96, whereby the restraining portion 99 is formed (FIG. 11). (See the alternate long and short dash line in the ZZ cross section).

In this way, the restraining portion 99 is provided at a position adjacent to the outlet portion 96 in such a region when the tension of the ascending wire 7A and the descending wire 7B is loosened by the rotation of the wire drum 8. The wire 7 (raising wire 7A, lowering wire 7B) tends to rise from the outer peripheral surface 8s of the wire drum 8. For example, in the ascending wire 7A wound around the wire drum 8, the portion extending in the tangential direction is restricted to the wire passage 94, so that when the tension of the ascending wire 7A is relaxed, the ascending wire 7A is used in the vicinity of the outlet portion 96 for ascending. It is easy to lift up at the beginning of winding of the wire 7A.

In addition, the restraining

portions

99 and 99 are provided at positions adjacent to the outlet portions 96 on both sides of the outlet portion 96, because the wire drum 8 is provided in the upside-down direction with respect to the drum accommodating space 92 of the drum housing 9. This is because the same wire drive device 6 can be used for the side door 1 (see FIG. 1) on the opposite side of the vehicle body by accommodating the above. That is, the wire drive device 6 of the window glass elevating device 3 used for the side door 1 on the right side of the vehicle body and the wire drive device 6 of the window glass elevating device 3 used for the side door 1 on the left side of the vehicle body are shared (with the left and right side doors 1). Because you can use the same one).

As described above, the suppressing portion 99 is formed at a position adjacent to the outlet portion 96. According to the wire drive device 6, even if the tension of the wire 7 (raising wire 7A / lowering wire 7B) wound around the wire drum 8 is loosened by the rotation of the wire drum 8, the wire 7 (raising wire 7A / lowering) It is possible to prevent the free portion of the wire 7B) from the wire drum 8 from unraveling from the drum accommodating space 92. As a result, it becomes possible to further prevent the wire 7 (raising wire 7A, lowering wire 7B) from being entangled.

As described above, it can be said that the restraining portion 99 is a protrusion provided on the inner peripheral surface of the drum accommodating wall portion 93 on the opening side. Although it has a simple structure, it has the above-mentioned effects.
