DETAILED DESCRIPTION

[0023] Hereinafter, a window regulator of one embodiment of the present application will be described with reference to the drawings. The window regulator is a lifting device that is fitted to a vehicle door for a vehicle and lifts and lowers a window glass of the vehicle. In particular, the present window regulator adopts a structure that reduces the moment generated by a yoke section of a drive motor by working on the layout of a guide rail. Furthermore, hereinafter, the lifting direction, the up direction, and the down direction of the window glass will be simply referred to as the lifting direction, the up direction, and the down direction. In addition, hereinafter, left, right, front, back, and up and down will be defined as shown in each drawing and described. Furthermore, in this embodiment, the lifting direction is the same as the up and down direction of the window regulator, and the vehicle width direction is the same as the front and back direction of the window regulator. In addition, the direction orthogonal to the lifting direction and the vehicle width direction is the left and right direction of the window regulator.

[0024] (Structure of vehicle door for vehicle)

[0025] Here, with reference to Figure 1 , the vehicle door for vehicle D to which the window regulator 1 is fitted will be described before the window regulator 1 is described. The vehicle door for vehicle D is provided to an automobile (vehicle). Furthermore, in Figure 1 , the vehicle door for vehicle D in which an outer panel is omitted is illustrated.

[0026] As shown in Figure 1 , the vehicle door for vehicle D includes a door main body Dl, a window glass G of the vehicle supported so as to be freely lifted and lowered along a glass guide (not shown) provided to the door main body Dl, and a window regulator 1 fitted to the door main body Dl to lift and lower the window glass G.

[0027] The door main body D1 has a storage portion D11 that stores the window glass G and a door window frame D12 that is provided above the storage portion D11. The storage portion D11 has an inner panel D13 on the inside of the vehicle cabin that is a door panel and an outer panel (not shown) on the outside of the vehicle cabin, and a door interior space is formed between the inner panel D13 and the outer panel. As shown in Figure 2 The window regulator 1 is attached to the inner panel D13 in the door interior space. In addition, as shown in Figure 1 The window regulator 1 is attached so as to be inclined toward the rear side in the vehicle front-rear direction with respect to the door main body D1.

[0028] (Configuration of the window regulator)

[0029] As shown in Figure 3 The window regulator 1 has a rail 2 that is provided along a lifting direction, a carrier 3 that supports the window glass G and is slidably attached to the rail 2, an up-side cable 4 and a down-side cable 5 that pull the carrier 3 so as to lift the carrier 3 along the rail 2, a drive portion 6 that is provided at a lower end portion (one end portion in the lifting direction) of the rail 2 and drives the up-side cable 4 and the down-side cable 5, and a pulley 7 (direction conversion portion) that is provided at an upper end portion (the other end portion in the lifting direction) of the rail 2 and converts the direction of the up-side cable 4.

[0030] In addition, as shown in Figure 4 The window regulator 1 has an up-side sliding bush 11 that is attached to an end portion of the up-side cable 4 on the carrier 3 side, an up-side spring 12 that imparts tension to the up-side cable 4 via the up-side sliding bush 11, a down-side sliding bush 13 that is attached to an end portion of the down-side cable 5 on the carrier 3 side, and a down-side spring 14 that imparts tension to the down-side cable 5 via the down-side sliding bush 13. That is, the window regulator 1 is a cable drive type window regulator that uses the cables 4, 5 to lift the carrier 3, and is a lower end rail type window regulator in which the drive portion 6 is provided at the lower end portion of the rail 2.

[0031] As shown in Figure 2 The rail 2 is an elongated metal member that extends along the lifting direction, and the upper end portion thereof is fixed to the inner panel D13 and the lower end portion thereof is fixed to the drive portion 6 (of the drum housing 44). In addition, the rail 2 is curved so as to protrude toward the outside of the vehicle cabin in the vehicle width direction.

[0032] As shown in Figure 4As shown, the guide rail 2 has: a flat plate portion 21 extending in the lifting direction; a right side plate portion 22 and a left side plate portion 23 (side plate portions) erected forward from the left and right ends of the flat plate portion 21 in the direction of its short side (orthogonal to the lifting direction); a right flange portion 24 protruding to the right from the front end of the right side plate portion 22; and a left flange portion 25 protruding to the left from the front end of the left side plate portion 23. The guide rail 2 supports the support plate 3 on the left side plate portion 23 and allows the support plate 3 to slide freely.

[0033] like Figure 3 As shown, one end of the ascending cable 4 is connected to the rotating drum 42 of the drive unit 6 (described later). The ascending cable 4 is released upward from the drive unit 6 and reaches the pulley 7. After the pulley 7 changes the direction downward, the other end of the ascending cable 4 is fitted to the support plate 3. On the other hand, one end of the descending cable 5 is connected to the rotating drum 42 of the drive unit 6. The descending cable 5 is released upward from the drive unit 6, and the other end of the descending cable 5 is fitted to the support plate 3.

[0034] Furthermore, the rising side cable 4a, which is positioned between the drive unit 6 and the pulley 7, is located on the flat plate portion 21 of the guide rail 2. When viewed from the vehicle width direction (the direction of the rotation axis of the rotating drum 42), the rising side cable 4a is overlapped with the flat plate portion 21 of the guide rail 2. As described above, the guide rail 2 is curved in the vehicle width direction; therefore, the rising side cable 4a positioned between the drive unit 6 and the pulley 7 is pressed against the middle portion of the flat plate portion 21 of the guide rail 2 in the vertical direction (see reference). Figure 2 Therefore, the flat plate portion 21 of the guide rail 2 functions as a cable support structure that supports the rising side cable 4a arranged between the drive unit 6 and the pulley 7 at the middle part in the vertical direction. On the other hand, the rising side cable 4b arranged between the pulley 7 and the support plate 3 and the descending side cable 5 of the rising side cable 4 are located at a position offset from the guide rail 2. When viewed from the width direction (rotation axis direction of the rotating drum 42), the rising side cable 4b and the descending side cable 5 are offset from the guide rail 2 in the left-right direction.

[0035] like Figure 4 and Figure 5 As shown, the support plate 3 is a plate-shaped component made of resin such as polyacetal, and is configured as a flat plate portion 21 facing the guide rail 2. The support plate 3 has two mounting holes 31, 31 on the left and right sides for mounting the window glass G; and a rail mounting portion 32, which is disposed on the rear side. Figure 4a left-right direction center of the inside (the right side of the inside in the figure); an ascending-side housing portion 33 provided on the left side of the rail fitting portion 32; a descending-side housing portion 34 provided on the left side of the ascending-side housing portion 33; a notch portion 35 provided on the right side of the rail fitting portion 32 on the rear side, avoiding the ascending-side cable 4a on the flat portion 21 of the rail 2; and a contacted portion 36 provided on the right side lower end portion of the notch portion 35, for the position limiting portion 64 of the drive portion 6 to contact.

[0036] The fitting holes 31, 31 are used to fasten, with bolts, a glass holder (not shown) that is fixed to the window glass G. By fastening the glass holder to the fitting holes 31, 31 with bolts, the window glass G is fitted to the sash 3 via the glass holder.

[0037] The rail fitting portion 32 is fitted so as to be slidable with respect to the left side plate portion 23 of the rail 2. That is, the sash 3 is supported by the rail fitting portion 32 so as to be liftable and lowerable with respect to the left side plate portion 23 of the rail 2.

[0038] As shown in Figure 4 The ascending-side housing portion 33 houses the ascending-side sliding bushing 11 and the ascending-side spring 12. Thus, in the ascending-side housing portion 33, the end portion of the ascending-side cable 4 on the sash 3 side is fitted via the ascending-side sliding bushing 11 and the ascending-side spring 12. On the other hand, the descending-side housing portion 34 houses the descending-side sliding bushing 13 and the descending-side spring 14. Thus, in the descending-side housing portion 34, the end portion of the descending-side cable 5 on the sash 3 side is fitted via the descending-side sliding bushing 13 and the descending-side spring 14.

[0039] The notch portion 35 extends in the lifting direction, and due to the notch portion 35, the sash 3 does not contact the ascending-side cable 4a that is routed between the drive portion 6 and the pulley 7. The separate contact of the ascending-side cable 4a that is routed between the drive portion 6 and the pulley 7 with respect to the rail 2 differs depending on the position in the lifting direction on the rail 2, and therefore the depth of the notch portion 35 in the front-rear direction is a depth at which the ascending-side cable 4a does not contact the sash 3 even when the sash 3 is positioned at the upper end position or the lower end position of the rail 2 at which the ascending-side cable 4a is farthest from the rail 2 (when the window glass G is fully opened or fully closed).

[0040] As shown in Figure 6 The pulley 7 has a pulley main body 37 that winds the ascending-side cable 4 and directionally converts the ascending-side cable 4, and a pulley shaft 38 that supports the pulley main body 37 so as to be rotatable.

[0041] The pulley shaft 38 penetrates the pulley support portion 26 provided at the upper end portion of the rail 2, and is fixed to the pulley support portion 26. In addition, a bolt portion 38a for fixing to the inner panel D13 is formed at the top end (rear end) of the pulley shaft 38. Therefore, as shown in Figure 2As shown, the upper end portion of the guide rail 2 is fixed to the inner panel D13 by a pulley shaft 38.

[0042] As shown in FIG. 1, the window regulator 1 includes a guide rail 2, a carrier 3, a drive section 6, and a belt 8. The guide rail 2 is a long member extending in the front-rear direction of the vehicle, and is provided on the inner panel D13 of the vehicle body. The carrier 3 is a long member extending in the front-rear direction of the vehicle, and is provided on the outer panel D14 of the vehicle body. The drive section 6 is a member for driving the carrier 3 in the up-down direction, and is provided on the inner panel D13. The belt 8 is a long member extending in the front-rear direction of the vehicle, and is provided on the inner panel D13. The belt 8 is a member for connecting the guide rail 2 and the carrier 3, and is provided so as to be wound around the pulley 7 provided on the guide rail 2 and the pulley 9 provided on the carrier 3. Figure 7 and Figure 8 As shown, the drive section 6 has a drive motor 41 capable of forward-reverse rotation driving, with a speed reducer 51, a resin-made rotary drum 42 driven to rotate by the drive motor 41, and a resin-made housing 43 that houses the rotary drum 42 and holds the drive motor 41. The housing 43 has a drum housing 44 into which the lower end portion of the guide rail 2 is fitted, and which houses and allows the rotary drum 42 to rotate, and a motor housing 45 that holds the drive motor 41.

[0043] The rotary drum 42 has the end portions of the ascending-side cable 4 and the descending-side cable 5 on the drive section 6 side connected thereto, and performs winding and unwinding of the ascending-side cable 4 and the descending-side cable 5 by rotation. In addition, the rotary drum 42 is configured to unwind the ascending-side cable 4 from the right-side cable unwinding position PI (first cable unwinding position), and to unwind the descending-side cable 5 from the left-side cable unwinding position P2 (second cable unwinding position). The right-side cable unwinding position PI of the rotary drum 42 (cable unwinding position of the ascending-side cable 4) overlaps the guide rail 2 in the left-right direction (orthogonal direction orthogonal to the up-down direction), and the left-side cable unwinding position P2 of the rotary drum 42 (cable unwinding position of the descending-side cable 5) is offset from the guide rail 2 in the left-right direction. Thus, it is configured such that, among the ascending-side cable 4a unwound from the right-side cable unwinding position PI of the rotary drum 42 to the pulley 7 and the descending-side cable 5 unwound from the left-side cable unwinding position P2 of the rotary drum 42 to the carrier 3, only the ascending-side cable 4a unwound from the right-side cable unwinding position PI of the rotary drum 42 to the pulley 7 overlaps the guide rail 2 in the left-right direction.

[0044] The drive motor 41 has a resin-made speed reducer 51 built into the motor housing 45 and pivotally mounting the rotary drum 42 to an output shaft, and a yoke section 52 (motor main body) provided adjacent to the right side of the speed reducer 51, rotating the rotary drum 42 via the speed reducer 51. The yoke section 52 includes a core formed by laminating metal plates, a copper wire wound around the core, a magnet generating a magnetic field around the core, and a metal yoke for holding the magnet, and is a heavy body in which most of the components are made of metal components. In particular, the drive section 6, the other components (speed reducer 51, rotary drum 42, and housing 43) of the drive motor 41 are made of resin, and the yoke section 52 is mainly made of metal components, and thus the yoke section 52 becomes a high-weight portion in the drive section 6 and the drive motor 41. Further, the yoke section 52 can be said to be a high-weight portion of the window regulator 1.

[0045] When the drive motor 41 is driven in forward rotation, the rotary drum 42 is driven in forward rotation, and in conjunction therewith, the descending side cable 5 is paid out and the ascending side cable 4 is taken up. Thus, the pallet 3 is pulled upward by the ascending side cable 4 and moves in the upward direction. Thus, the window glass G attached to the pallet 3 is raised (raising operation of the window glass G). On the other hand, when the drive motor 41 is driven in reverse rotation, the rotary drum 42 is driven in reverse rotation, and in conjunction therewith, the ascending side cable 4 is paid out and the descending side cable 5 is taken up. Thus, the pallet 3 is pulled downward by the descending side cable 5 and moves downward. Thus, the window glass G attached to the pallet 3 is lowered (lowering operation of the window glass G). By these operations, the pallet 3 and the window glass G are raised and lowered along the guide rail 2.

[0046] The rotary drum housing 44 is formed with: two fixing holes 61, 61 for fixing the rotary drum housing 44 to the inner panel D13 with bolts 61a, 61a; a rotary drum accommodating portion 62 that accommodates the rotary drum 42 and makes the rotary drum 42 rotatable; a fitting hole 63 that is provided at the right upper portion of the rotary drum accommodating portion 62, fits the lower end portion of the guide rail 2, and is provided at the front side (the proximal side in (a)) of the fitting hole 63; and a position restricting portion 64 that is provided at the front side of the fitting hole 63 and contacts the contacted portion 36 of the pallet 3 in the fully open state of the window glass G. Figure 7 The position restricting portion 64 contacts the contacted portion 36 of the pallet 3 in the fully open state of the window glass G and restricts the downward movement of the pallet 3.

[0047] The fitting hole 63 fits the lower end portion of the guide rail 2. The lower end portion of the guide rail 2 is fixed to the rotary drum housing 44 by the fitting hole 63. The fitting hole 63 is provided so as to overlap the cable pay-out position P1 on the right side of the rotary drum 42 accommodated in the rotary drum accommodating portion 62 in the left-right direction (a direction orthogonal to the raising and lowering direction and the vehicle width direction), and thus the guide rail 2 fitted in the fitting hole 63 is provided so as to overlap the cable pay-out position P1 on the right side of the rotary drum 42 in the left-right direction. Therefore, the guide rail 2 is configured so as to overlap the ascending side cable 4a that is paid out from the cable pay-out position P1 on the right side of the rotary drum 42 to the belt pulley 7 in the left-right direction. Thus, it is possible to bring the guide rail 2 close to the yoke portion 52 of the drive motor 41. In the present embodiment, the guide rail 2 and the yoke portion 52 are provided so as to overlap in the left-right direction.

[0048] The motor housing 45 houses the speed reducer 51, the output shaft of the speed reducer 51 is pivotally attached to the rotary drum 42, and the opening of the rotary drum accommodating portion 62 of the rotary drum housing 44 is covered. In addition, three fixing portions 71, 71, 71 for fixing the motor housing 45 to the rotary drum housing 44 are formed in the motor housing 45. Furthermore, a part of the three fixing portions 71 is disposed at a position overlapping the guide rail 2 in the left-right direction.

[0049] (Action and Effect of the Embodiment)

[0050] According to the above-described configuration of the embodiment, in the left-right direction (orthogonal direction to the up-down direction), the guide rail 2 is arranged so as to overlap the up-side cable 4a that is paid out from the right-side cable pay-out position Pl of the rotating drum 42 to the pulley 7, among the up-side cable 4a that is paid out from the right-side cable pay-out position Pl of the rotating drum 42 to the pulley 7 and the down-side cable 5 that is paid out from the left-side cable pay-out position P2 of the rotating drum 42 to the bracket 3, whereby the width dimension of the window regulator 1 can be reduced, and the stress on the inner panel D13 due to the moment caused by the weight of the yoke portion 52 can be reduced.

[0051] That is, due to the impact at the time of closing the vehicle door D, a strong inertial force in the vehicle width direction is generated in the yoke portion 52 that is a high-weight portion, and a moment that has the yoke portion 52 as a force point and has the guide rail 2 as a rotation fulcrum (rotation axis) and has the fixed portion (the fixed holes 61, 61 and the bolt portion 38a of the pulley shaft 38) of the inner panel D13 as an action point is generated. Therefore, the farther apart the yoke portion 52 and the guide rail 2 are in the left-right direction (orthogonal direction to the up-down direction), the stronger stress is generated on the inner panel D13 according to the principle of a lever.

[0052] In this regard, in the above-described configuration of the embodiment, in which the yoke portion 52 is adjacent to the right side of the speed reducer 51, the guide rail 2 is configured so as to overlap the up-side cable 4a that is paid out from the right-side cable pay-out position Pl of the rotating drum 42, and therefore the yoke portion 52 can be brought closer to the guide rail 2, and the stress on the inner panel D13 due to the moment caused by the weight of the yoke portion 52 at the time of closing the vehicle door D can be reduced. Thus, the damage or the bending of the inner panel D13 can be suppressed.

[0053] In addition, in the conventional window regulator, due to the impact at the time of closing the vehicle door D, it is possible that vibration of the guide rail 2 in the torsion direction caused by the weight of the yoke portion 52 results in the guide rail 2 coming into contact with the bracket 3 and generating a knocking sound, but by bringing the yoke portion 52 closer to the guide rail 2 in the left-right direction, the vibration of the guide rail 2 caused by the weight of the yoke portion 52 can also be reduced, and the torsion of the guide rail 2 and the generation of the knocking sound of the guide rail 2 caused by the bracket 3 can be suppressed.

[0054] Further, in view of these effects, the distance between the yoke portion 52 (e.g., the center thereof) and the guide rail 2 (e.g., the center thereof) in the left-right direction is preferably equal to or less than the distance between the guide rail 2 (e.g., the center thereof) and the fixed portion (e.g., the center thereof) of the inner panel D13 in the left-right direction.

[0055] In addition, since the ascending-side cable 4a that is disposed between the driving section 6 and the pulley 7, the ascending-side cable 4b that is disposed between the pulley 7 and the support plate 3, and the descending-side cable 5 are among the cables that are disposed on the guide rail 2, only the ascending-side cable 4a that is disposed between the driving section 6 and the pulley 7 is configured to be disposed on the guide rail 2, and thus, the width dimension (dimension in the left-right direction) of the guide rail 2 can be reduced. Thus, the power window regulator 1 can be made lighter.
