Detailed Implementation

[0030] Hereinafter, a method for assembling a window regulator and guide rail according to an embodiment of the present invention will be described with reference to the accompanying drawings. This window regulator is a lifting device installed inside a vehicle door (e.g., an automobile) to raise and lower the window glass of the vehicle door. In particular, this window regulator is a window regulator in which a guide structure for improving the assembly workability of the guide rail is provided in the support plate and the rotating cylinder housing. Furthermore, the direction of raising and lowering the vehicle window glass will be simply referred to as the raising and lowering direction. Additionally, the left-right, front-back, and up-down directions will be defined below as shown in the figures. Furthermore, in this embodiment, the raising and lowering direction is set to be consistent with the up-down direction of the window regulator, and the vehicle width direction is set to be consistent with the front-back direction of the window regulator. Furthermore, the direction orthogonal to the raising and lowering direction and the vehicle width direction is defined as the left-right direction of the window regulator.

[0031] (Components of a car window regulator)

[0032] like Figures 1 to 3 As shown, the window regulator 10 is mounted on the vehicle door 1 and includes: a guide rail 11, which is arranged along the lifting direction; a support plate 12, which supports the window glass 3 and is slidably mounted on the guide rail 11; an upward cable 13 and a downward cable 14, which pull the support plate 12; a drive unit 15, which is arranged at the lower end of the guide rail 11 and drives the upward cable 13 and the downward cable 14; a pulley 16, which is arranged at the upper end of the guide rail 11 via a pulley bracket 18 and changes the direction of the upward cable 13; and a cable guide 17, which is arranged at approximately the center of the long side of the guide rail 11 and supports the upward cable 13 arranged between the pulley 16 and the drive unit 15. That is, the window regulator 10 is a cable-driven window regulator that uses cables 13 and 14 to raise and lower the support plate 12, and it is a lower end rail type window regulator with the drive unit 15 disposed at the lower end of the guide rail 11.

[0033] One end of the ascending cable 13 is fitted to the support plate 12, and the other end is connected to the rotating drum 22 of the drive unit 15 via the pulley 16 (described later). On the other hand, one end of the descending cable 14 is fitted to the support plate 12, and the other end is connected to the rotating drum 22.

[0034] The drive unit 15 includes: a motor 21; a cylindrical rotating drum 22 driven by the motor 21 to rotate, thereby winding and unwinding the ascending cable 13 and the descending cable 14; a reducer (not shown) that transmits the rotation of the motor 21 to the rotating drum 22; and a housing 25 including a drum housing 23 and a motor housing 24. The drum housing 23 is fitted with the lower end of the guide rail 11, houses the rotating drum 22, and allows the rotating drum 22 to rotate freely. The motor housing 24 holds the motor 21. The reducer is built into the motor housing 24 and is fixed to the drum housing 23. Furthermore, the motor housing 24 connects the output shaft of the reducer to the rotating drum 22 and covers the opening of the drum housing 71 (described later) of the drum housing 23. Details of the drum housing 23 will be described later.

[0035] When motor 21 is driven in a forward direction, rotating drum 22 rotates forward, and simultaneously, the descending cable 14 is released and the ascending cable 13 is wound up. As a result, the support plate 12 is pulled upward in the lifting direction by the ascending cable 13. Consequently, the window glass 3 mounted on the support plate 12 rises. Conversely, when motor 21 is driven in a reverse direction, rotating drum 22 reverses, and simultaneously, the ascending cable 13 is released and the descending cable 14 is wound up. Consequently, the support plate 12 is pulled downward in the lifting direction by the descending cable 14. Consequently, the window glass 3 mounted on the support plate 12 descends. Thus, the support plate 12 and the window glass 3 rise and fall along the guide rail 11.

[0036] like Figure 1 and Figure 3 As shown, the guide rail 11 is formed by bending a long, plate-shaped metal plate outwards from the outside of the carriage with a specified curvature, and is configured to tilt towards the rearward side relative to the vehicle door 1 in the forward-backward direction of the vehicle.

[0037] In addition, such as Figure 2 and Figure 4 As shown in (a), the guide rail 11 integrally comprises: a base plate portion 31 extending in the lifting direction; a right side plate portion 32 and a left side plate portion 33, which are erected forward from both ends in the width direction orthogonal to the lifting direction and extend in the lifting direction; a right flange portion 34 protruding to the right from the front end of the right side plate portion 32 and extending in the lifting direction; and a left flange portion 35 protruding to the left from the top end of the left side plate portion 33 and extending in the lifting direction. The right flange portion 34 and the left flange portion 35 are formed to be substantially parallel to the base plate portion 31. That is, it can also be said that the right side plate portion 32 is erected rearward from the right flange portion 34, and the left side plate portion 33 is erected rearward from the left flange portion 35. The guide rail 11 supports the support plate 12 via the right side plate portion 32 and allows the support plate 12 to slide freely. Furthermore, in this embodiment, the bottom plate portion 31 is a flat plate portion guided by the first fitting guide wall 81, and the right flange portion 34 is a flat plate portion guided by the first insertion guide wall 61. Additionally, the right side plate portion 32 is a side plate portion guided by the second insertion guide wall 62 and the second fitting guide wall 82.

[0038] Next, refer to Figures 4 to 6 The pallet 12 is described below. Figure 4 As shown, the support plate 12 is made of resin (e.g., polyacetal resin) and has: a plate-shaped main body 40; two mounting holes 41, 42 formed at the left and right ends of the main body 40 for mounting the window glass 3; and a track mounting part 42 formed on the rear surface side of the main body 40. Figure 5 The guide rail 11 has a cable assembly 43 located slightly to the right of the center of the inner side of (a); a descending cable assembly 43 disposed on the left side of the rail assembly 42; an ascending cable assembly 44 disposed on the left side of the descending cable assembly 43; and a plurality of sliding fins 45 that press against the right flange 34 and the left flange 35 of the guide rail 11. Additionally, the support plate 12 has an insertion guide 46 formed on the upper side of the rail assembly 42.

[0039] Two mounting holes 41, 41 are used to assemble two glass retainers (not shown) fixed to the window glass 3. By assembling the two glass retainers fixed to the window glass 3 into the mounting holes 41, 41, the window glass 3 is assembled onto the support plate 12 via the two glass retainers.

[0040] The descending side cable assembly 43 is fitted with one end of the descending side cable 14. On the other hand, the ascending side cable assembly 44 is fitted with one end of the ascending side cable 13. That is, the support plate 12 is pulled downward in the lifting direction by the descending side cable 14 via the descending side cable assembly 43, and pulled upward in the lifting direction by the ascending side cable 13 via the ascending side cable assembly 44.

[0041] The rail assembly part 42 includes: an upper sliding part 51 formed at the upper end of the main body part 40, which slides on the right side plate part 32 of the guide rail 11; and a lower sliding part 52 formed at the lower end of the main body part 40, which slides on the right side plate part 32 of the guide rail 11. The upper sliding part 51 and the lower sliding part 52 have a right sliding surface that slides on the right surface of the right side plate part 32, and a left sliding surface that slides on the left surface of the right side plate part 32, sliding relative to both the front and back surfaces of the right side plate part 32. Figure 4 As shown in (b), the upper sliding portion 51 and the lower sliding portion 52 are configured to allow the right side plate portion 32 and the right flange portion 34 of the guide rail 11 to be inserted. This configuration allows the support plate 12 to be slidably mounted onto the guide rail 11 by inserting the upper sliding portion 51 and the lower sliding portion 52 into the right side plate portion 32 and the right flange portion 34 of the guide rail 11. Furthermore, the upper sliding portion 51 is an example of an insertion portion for inserting the guide rail 11.

[0042] like Figure 4 (b) Figure 5 and Figure 6 As shown, the insertion guide portion 46 includes: a plate-shaped first insertion guide wall 61, which is formed by extending the front inner surface 51a of the upper sliding portion 51 upward (near the front in the insertion direction) from the upper edge of the upper sliding portion 51; and a plate-shaped second insertion guide wall 62, which is formed by extending the right sliding surface 51b of the upper sliding portion 51 upward from the upper edge of the upper sliding portion 51. The front inner surface 51a of the upper sliding portion 51 is an inner surface facing the front surface of the right flange portion 34 of the guide rail 11, and is an example of the first inner surface of the insertion portion. Furthermore, the right sliding surface 51b of the upper sliding portion 51 is an inner surface facing the right surface of the right side plate portion 32 of the guide rail 11, and is an example of the second inner surface of the insertion portion. To improve rigidity, the first insertion guide wall 61 is formed to be wider than the front inner surface 51a of the upper sliding portion 51.

[0043] The rear surface of the first insertion guide wall 61 is continuously formed without steps with the front inner surface 51a of the upper sliding portion 51. The rear surface of the first insertion guide wall 61 serves as a guide surface in the front-rear direction to guide the right flange portion 34 of the guide rail 11 into the upper sliding portion 51. Therefore, by sliding the right flange portion 34 of the guide rail 11 into contact with the rear surface of the first insertion guide wall 61 while moving the guide rail 11 towards the upper sliding portion 51, the right flange portion 34 of the guide rail 11 is guided into the upper sliding portion 51 in the front-rear direction and inserted into the upper sliding portion 51.

[0044] On the other hand, the left surface of the second insertion guide wall 62 is continuously formed without steps with the right sliding surface 51b of the upper sliding portion 51. The left surface of the second insertion guide wall 62 becomes a guide surface in the left-right direction to guide the right side plate portion 32 of the guide rail 11 into the upper sliding portion 51. Therefore, by sliding the right side plate portion 32 of the guide rail 11 into contact with the left surface of the second insertion guide wall 62 while moving the guide rail 11 towards the upper sliding portion 51, the right side plate portion 32 of the guide rail 11 is guided into the upper sliding portion 51 in the left-right direction and inserted into the upper sliding portion 51.

[0045] Thus, through the first insertion guide wall 61, the right flange portion 34 of the guide rail 11 is guided into the upper sliding portion 51 in the front-back direction, and through the second insertion guide wall 62, the right side plate portion 32 of the guide rail 11 is guided into the upper sliding portion 51 in the left-right direction. Therefore, when the right flange portion 34 and the right side plate portion 32 of the guide rail 11 are inserted into the upper sliding portion 51, the guide rail 11 is naturally aligned with the upper sliding portion 51 in both the left-right and front-back directions through the first and second insertion guide walls 61 and 62. Therefore, without special alignment, the right side plate portion 32 and the right flange portion 34 of the guide rail 11 can be easily inserted into the upper sliding portion 51.

[0046] Next, refer to Figure 4 , Figure 7 and Figure 8 The rotating cylinder housing 23 will be described below. For example... Figure 7 and Figure 8 As shown, the rotating cylinder housing 23 includes: a rotating cylinder housing 71 for housing the rotating cylinder 22 and allowing the rotating cylinder 22 to rotate freely; two fixing holes 72, 72 for fixing the rotating cylinder housing 23 to the inner panel (not shown) of the vehicle door 1; a fitting hole 73 for inserting and fitting the lower end of the guide rail 11; and a fitting guide 75 formed on the upper side of the fitting hole 73.

[0047] like Figure 4 (c) Figure 7 and Figure 8As shown, the fitting guide portion 75 integrally comprises: a plate-shaped first fitting guide wall 81, which is formed by extending the rear inner surface 73a of the fitting hole 73 upward (near the front in the insertion direction) from the edge of the fitting hole 73; and a plate-shaped second fitting guide wall 82, which is formed by extending the right inner surface 73b of the fitting hole 73 upward from the edge of the fitting hole 73. The rear inner surface 73a of the fitting hole 73 is the inner surface facing the rear surface of the bottom plate portion 31 of the guide rail 11, and is an example of the first inner surface of the fitting hole 73. In addition, the right inner surface 73b of the fitting hole 73 is the inner surface facing the right surface of the right side plate portion 32 of the guide rail 11, and is an example of the second inner surface of the fitting hole 73. Furthermore, the fitting hole 73 is formed to be inclined forward to match the curvature of the guide rail 11, and correspondingly, the first fitting guide wall 81 and the second fitting guide wall 82 are also formed to be inclined forward.

[0048] The front surface of the first fitting guide wall 81 is continuously formed without steps with the rear inner surface 73a of the fitting hole 73. The front surface of the first fitting guide wall 81 serves as a guide surface in the front-rear direction to guide the bottom plate portion 31 of the guide rail 11 into the fitting hole 73. Therefore, by sliding the bottom plate portion 31 of the guide rail 11 into contact with the front surface of the first fitting guide wall 81 while moving the guide rail 11 toward the fitting hole 73, the bottom plate portion 31 of the guide rail 11 is guided into the fitting hole 73 in the front-rear direction and inserted into the fitting hole 73.

[0049] On the other hand, the left surface of the second fitting guide wall 82 is continuously formed without steps with the right inner surface 73b of the fitting hole 73. The left surface of the second fitting guide wall 82 becomes a guide surface in the left-right direction to guide the right side plate portion 32 of the guide rail 11 into the fitting hole 73. Therefore, by sliding the right side plate portion 32 of the guide rail 11 into contact with the left surface of the second fitting guide wall 82 while moving the guide rail 11 toward the fitting hole 73, the right side plate portion 32 of the guide rail 11 is guided into the fitting hole 73 in the front-back direction and inserted into the fitting hole 73.

[0050] Thus, the bottom plate portion 31 of the guide rail 11 is guided into the fitting hole 73 in the front-to-back direction by the first fitting guide wall 81, and the right side plate portion 32 of the guide rail 11 is guided into the fitting hole 73 in the left-to-right direction by the second fitting guide wall 82. Therefore, when the guide rail 11 is inserted and fitted into the fitting hole 73, the guide rail 11 is naturally aligned with the fitting hole 73 in the left-to-right direction and the front-to-back direction by the first fitting guide wall 81 and the second fitting guide wall 82. Therefore, the guide rail 11 can be easily inserted into the fitting hole 73 without special alignment.

[0051] Here, refer to Figure 9 and Figure 10The guide rail assembly operation (the assembly method of guide rail 11) will be described. In this embodiment, after the guide rail 11 is assembled onto the pallet 12, the lower end of the guide rail 11, which is assembled onto the pallet 12, is assembled onto the rotary drum housing 23. Therefore, the assembly operation of assembling the guide rail 11 onto the pallet 12 is described as the first guide rail assembly operation, and the assembly operation of assembling the lower end of the guide rail 11, which is assembled onto the pallet 12, onto the rotary drum housing 23 is described as the second guide rail assembly operation.

[0052] First, refer to Figure 9 The assembly operation of the first guide rail is described below. The assembly operation of the first guide rail is performed with the pulley bracket 18 and pulley 16 assembled at the upper end of the guide rail 11.

[0053] In the first guide rail assembly operation, firstly, as Figure 9 As shown in (a), at the lower end of the guide rail 11, the right flange portion 34 is brought into contact with the first insertion guide wall 61. Specifically, the front surface of the right flange portion 34 is brought into contact with the rear surface of the first insertion guide wall 61.

[0054] After that, as Figure 9 As shown in (b), while keeping the right flange 34 in contact with the first insertion guide wall 61, the guide rail 11 is slid to the right, and at the lower end of the guide rail 11, the right side plate 32 comes into contact with the second insertion guide wall 62. Specifically, the right surface of the right side plate 32 comes into contact with the left surface of the second insertion guide wall 62.

[0055] Once the right flange 34 and the right side plate 32 are in contact with the first insertion guide wall 61 and the second insertion guide wall 62 respectively, as Figure 9 As shown in (c), while the right flange 34 and the right plate 32 are slidably contacted with the first insertion guide wall 61 and the second insertion guide wall 62 respectively, the guide rail 11 is moved towards the upper sliding portion 51, thereby inserting the right flange 34 and the right plate 32 into the upper sliding portion 51. When the right flange 34 and the right plate 32 are slidably contacted with the first insertion guide wall 61 and the second insertion guide wall 62 respectively, while the guide rail 11 is moved towards the upper sliding portion 51, the right flange 34 and the right plate 32 are guided by the first insertion guide wall 61 and the second insertion guide wall 62 into the upper sliding portion 51, and the right flange 34 and the right plate 32 are inserted into the upper sliding portion 51. Then, the guide rail 11 is inserted until the lower end of the guide rail 11 passes the lower sliding portion 52, thereby assembling the guide rail 11 onto the support plate 12.

[0056] Next, refer to Figure 10 The assembly operation of the second guide rail will be explained. As mentioned above, the assembly operation of the second guide rail is performed after the assembly operation of the first guide rail, and is performed while the guide rail 11 is mounted on the tray 12.

[0057] During the assembly of the second guide rail, such as Figure 10 As shown in (a), at the lower end of the guide rail 11, the base plate portion 31 is brought into contact with the first fitting guide wall 81. Specifically, the rear surface of the base plate portion 31 is brought into contact with the front surface of the first fitting guide wall 81.

[0058] After that, as Figure 10 As shown in (b), while keeping the base plate 31 in contact with the first fitting guide wall 81, the guide rail 11 is slid to the right, and at the lower end of the guide rail 11, the right side plate 32 comes into contact with the second fitting guide wall 82. Specifically, the right surface of the right side plate 32 comes into contact with the left surface of the second fitting guide wall 82.

[0059] Once the base plate 31 and the right side plate 32 come into contact with the first fitting guide wall 81 and the second fitting guide wall 82 respectively, as Figure 10 As shown in (c), while the base plate 31 and the right side plate 32 are in sliding contact with the first fitting guide wall 81 and the second fitting guide wall 82 respectively, the guide rail 11 is moved toward the fitting hole 73, thereby inserting the lower end of the guide rail 11 into the fitting hole 73. When the base plate 31 and the right side plate 32 are in sliding contact with the first fitting guide wall 81 and the second fitting guide wall 82 respectively, and the guide rail 11 is moved toward the fitting hole 73, the base plate 31 and the right side plate 32 are guided into the fitting hole 73 by the first fitting guide wall 81 and the second fitting guide wall 82, and the lower end of the guide rail 11 is inserted into the fitting hole 73. Thus, the lower end of the guide rail 11 is fitted into the fitting hole 73, and the guide rail 11 is assembled into the rotary cylinder housing 23.

[0060] (The role and effects of the implementation method)

[0061] According to the configuration described above, since the first fitting guide wall 81 and the second fitting guide wall 82 are provided in the rotary cylinder housing 23, when the guide rail 11 is inserted and fitted into the fitting hole 73, the guide rail 11 is naturally aligned with the fitting hole 73 in the left-right and front-back directions by means of the first fitting guide wall 81 and the second fitting guide wall 82. Therefore, the guide rail 11 can be easily inserted into the fitting hole 73 without special alignment. In other words, simply contacting the bottom plate portion 31 and the right side plate portion 32 of the guide rail 11 with the first fitting guide wall 81 and the second fitting guide wall 82 is sufficient to align the guide rail 11 in the left-right and front-back directions during insertion. This improves the ease of assembly of the guide rail 11. This also effectively benefits from the viewpoint of automating the assembly operation of the second guide rail.

[0062] Furthermore, according to the configuration of the above embodiment, since the first fitting guide wall 81 and the second fitting guide wall 82 are provided at the edge of the fitting hole 73, the first fitting guide wall 81 and the second fitting guide wall 82 will function as reinforcing ribs, thereby improving the rigidity of the fitting hole 73.

[0063] For example, in this type of window regulator 10, when the window glass 3 is raised or lowered (especially at the start of raising or lowering), a force that causes the window glass 3 to tilt in the forward or backward direction of the vehicle will come into play, and the guide rail 11 may bend to the left or right due to this force. If the guide rail 11 bends to the left or right, the raising and lowering of the window glass 3 will be reduced, resulting in a problem where the window glass 3 cannot be raised or lowered smoothly.

[0064] In this regard, in the above embodiment, the rigidity of the wall constituting the fitting hole 73 is improved by the first fitting guide wall 81 and the second fitting guide wall 82, thereby suppressing the bending of the guide rail 11 in the left and right directions through the fitting hole 73 and preventing the reduction of the lifting and lowering performance of the window glass 3.

[0065] Furthermore, according to the configuration of the above embodiment, since the first insertion guide wall 61 and the second insertion guide wall 62 are provided on the tray 12, when the guide rail 11 is inserted into the upper sliding portion 51, the guide rail 11 is naturally aligned with the upper sliding portion 51 in the left-right and front-back directions by means of the first insertion guide wall 61 and the second insertion guide wall 62. Therefore, without special alignment, the right side plate portion 32 and the right flange portion 34 of the guide rail 11 can be easily inserted into the upper sliding portion 51. In other words, simply contacting the right side plate portion 32 and the right flange portion 34 of the guide rail 11 with the first insertion guide wall 61 and the second insertion guide wall 62 is sufficient to align the guide rail 11 in the left-right and front-back directions during insertion. This improves the ease of assembly of the guide rail 11. This also effectively benefits from the viewpoint of automating the first guide rail assembly operation.

[0066] Furthermore, according to the configuration of the above embodiment, since the first insertion guide wall 61 and the second insertion guide wall 62 are provided at the edge of the upper sliding part 51, the first insertion guide wall 61 and the second insertion guide wall 62 will function as reinforcing ribs, thereby improving the rigidity of the upper sliding part 51.

[0067] For example, in this type of window regulator 10, when the window glass 3 is raised or lowered (especially when it starts to rise or fall), the force that causes the window glass 3 to tilt in the direction of the vehicle's front and rear will come into play. Since this force applies a strong load to the upper sliding part 51, it may cause the upper sliding part 51 to break.

[0068] In this regard, in the above embodiment, the rigidity of the constituent wall of the upper sliding part 51 is improved by the first insertion guide wall 61 and the second insertion guide wall 62, thereby preventing or suppressing the upper sliding part 51 from breaking due to the tilt of the window glass 3.

The flat plate portion is guided by the first fitting guide wall 81. A second fitting guide wall 82 is formed by extending the inner surface of the fitting hole 73 that faces the side plate portion (right plate portion 32 or left plate portion 33) of the guide rail 11. The side plate portion is guided by the second fitting guide wall 82. For example, it is also possible to... Figure 11 As shown, the first fitting guide wall 81 is formed by extending the inner surface of the fitting hole 73 that faces the front surface of the right flange portion 34, and the right flange portion 34 of the guide rail 11 is guided by the first fitting guide wall 81. The second fitting guide wall 82 is formed by extending the inner surface of the fitting hole 73 that faces the left surface of the right side plate portion 32, and the right side plate portion 32 is guided by the second fitting guide wall 82.

It is possible to form the first insertion guide wall 61 by extending the inner surface of the upper sliding portion 51 that faces the flat plate portion (bottom plate portion 31, right flange portion 34 or left flange portion 35) of the guide rail 11, and the flat plate portion is guided by the first insertion guide wall 61, and the second insertion guide wall 62 is formed by extending the inner surface of the upper sliding portion 51 that faces the side plate portion (right plate portion 32 or left plate portion 33) of the guide rail 11, and the side plate portion is guided by the second insertion guide wall 62. For example, it can also be configured such that the inner surface of the upper sliding portion 51 facing the rear surface of the right flange portion 34 is extended to form a first insertion guide wall 61, through which the right flange portion 34 of the guide rail 11 is guided, and the inner surface of the upper sliding portion 51 facing the left surface of the right side plate portion 32 is extended to form a second insertion guide wall 62, through which the right side plate portion 32 is guided.

[0073] Furthermore, although the guide rail 11 is configured in the above embodiment to have a base plate portion 31, a right side plate portion 32, a left side plate portion 33, a right flange portion 34, and a left flange portion 35, it is not limited thereto.
