Description

  The present invention relates to a window regulator for raising and lowering a window glass of a vehicle door and a vehicle door structure using the window regulator.

Patent 3274317 Special table 2002-522678

  Patent Document 1 discloses a wire type window regulator device as shown in FIG. In the wire type window regulator device, a drum for winding a wire for raising and lowering the window glass is pivotally supported by a base extending from the guide rail. Therefore, it can be set as the outerless type which does not require an outer pipe for a wire. From the vicinity of the center of the guide rail 101 of the window regulator 100, a base portion 102 extends sideways. A cup-shaped case portion 104 surrounding the outer peripheral surface and the upper surface of the drum 103 is attached to the base portion 102. The drum 103 is pivotally supported by a cylindrical drum support portion protruding from the top surface of the case portion 104. Further, a drive mechanism 105 is arranged from the opening side of the case portion 104, the output shaft of the drive mechanism 105 is engaged with the drum 103, the drum 103 is sandwiched between the case portion 104 and the drive mechanism 105, and the mounting screw 106 is used. Can be attached to one piece.

  Further, the window regulator disclosed in Patent Document 2 also discloses a plate-like member that extends in a lateral direction from the vicinity of the middle of a guide rail called a support portion. In this device, a cylindrical inner space for accommodating the drum is formed in the plate-like member, and a drive cable introduction path is formed so as to communicate with the inner space from the outer peripheral edge of the plate-like member.

  When a part is lightened, its strength tends to decrease. The interior of an automobile door is formed in a hollow shape, and various components are incorporated in the hollow interior. A window regulator is one of the components. These various parts, window regulators or door inner panels may be individually reduced in weight, but such weight reduction has a limit in maintaining the strength of the parts themselves.

  The window regulator needs to be easily assembled or maintained. For example, an opening is formed in the center of the inner panel of an automobile, and wind glass, guide rails, etc. are arranged outside the room (the hollow interior side of the door) that allows water to enter from the opening. In addition, electrical components such as a motor are arranged indoors where waterproofing is required. The guide rail must be placed outside the room allowing water to enter. Therefore, a long guide rail is inserted into the outdoor side from the opening, and the upper and lower ends of the guide rail are fixed to the outdoor side surface around the opening. Since such an operation is difficult to assemble, the cable may be damaged at the periphery of the opening of the inner panel during the assembly. Furthermore, if the structure is such that parts are removed to the outside of the room when disassembling for maintenance or the like, work on both the inside and outside is required with the opening as a boundary, and the work becomes complicated.

  According to the window regulator of Patent Document 1, the drum 103 is housed in the case portion 104 and the case portion 104 is covered by the drive mechanism 105. For this reason, since the load applied when the wind screen is raised and lowered is transmitted from the drum 103 to the base portion 102, if the base portion 102 or the guide rail is further reduced in weight, the strength of the component itself that supports the raising and lowering of the wind screen is maintained. There is a risk of disappearing. Further, in Patent Document 2, since it is considered that the drum is sandwiched between the indoor side and the outdoor side member, assembly work and maintenance work become complicated. In addition, a groove is formed in the plate-like member to protect the cable from the outdoor side, but the indoor side is not protected, so there is a risk of scratching the cable near the outer edge of the opening formed in the inner panel. .

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a window regulator that can reduce the weight of the door and facilitate assembly work and maintenance work, and a door structure using the window regulator.

  A window regulator according to the present invention (Claim 1) is a window regulator that is attached to an inner panel in which an opening of a vehicle door is formed, and has a guide rail that has upper and lower mounting portions attached to the inner panel, and a guide for the guide rail. A motor bracket that extends laterally from the rail, a motor that is fixed to the motor bracket, and a mounting portion that extends beyond the motor. The mounting portion and the mounting portion of the guide rail open the inner panel. It is characterized by being fixed around the part.

  In such a window regulator, a communication port is formed in the motor bracket, an output shaft is extended from the communication port, and the motor is arranged on the indoor side or the outdoor side of the motor bracket, and is rotated by the output shaft of the motor, It consists of a drum that winds up the inner cable that raises and lowers the wind glass, and a housing that is inserted into the communication port and is attached to the motor bracket and pivotally supports the drum from the opposite side of the motor.

  The window regulator according to the present invention (Claim 1) is fixed in the vicinity of the periphery of the opening by an attaching portion provided above and below the guide rail and an attaching portion provided on the motor bracket. Therefore, since the opening of the inner panel can be equally supported at a large number of points without being biased, the window regulator can act as a reinforcing member even if the opening of the inner panel is wide. Moreover, since the window regulator and the door panel can be integrated to support the load related to the raising and lowering of the window glass and to maintain the strength, the thickness of each member can be reduced. Therefore, it is possible to increase the indoor living space by effectively utilizing the space inside the door. Furthermore, the weight of the entire door is reduced.

  In such a window regulator, a communication port is formed in the motor bracket, an output shaft is extended from the communication port, and the motor is arranged on the indoor side or the outdoor side of the motor bracket, and is rotated by the output shaft of the motor, It consists of a drum that winds up the inner cable that raises and lowers the wind glass, a drum that passes through the communication port, is attached to the motor bracket, and a housing that pivotally supports the drum from the opposite side of the motor. When the guide groove of the inner cable leading from the outer periphery to the communication port is formed on the surface on the indoor side (Claim 2), even if the drum is disposed in the communication port of the motor bracket, it is locked to the drum. The inner cable is guided to the drum by the guide groove so as not to interfere with the motor bracket. Therefore, the drum can be rotated inside the communication port to wind up the inner cable, so that the thickness can be reduced by the thickness of the motor bracket. Further, since the guide groove is formed by bending the motor bracket, the bent portion acts as a reinforcing rib, so that the strength of the motor bracket can be increased and the plate thickness can be further reduced. Furthermore, since the indoor side of the inner cable is protected by the guide groove, the inner cable is prevented from being damaged at the outer edge of the opening of the inner panel during assembly.

  Further, when the housing includes a storage portion that rotatably stores the drum, and a flange portion that extends outward from the opening end of the storage portion, and is fixed to the motor bracket by the flange portion on the outdoor side (claim) Item 3) Since the drum can be supported with a simple structure in which the drum is sandwiched between the housing and the motor, assembly is easy. Further, the housing includes a storage portion that rotatably stores the drum, and a flange portion that extends outward from an opening end of the storage portion, the storage portion is inserted from the communication port toward the outside, and the flange portion is inserted. When locking to the motor bracket indoors (Claim 4), a structure in which the drum is sandwiched with a simple structure is adopted, the housing is fixed to the motor bracket from the indoor side, and the drum is stored in the housing from the indoor side. Then, the opening side of the storage part is closed with a motor as it is. Then, since all work is performed from the indoor side, assembly and subsequent maintenance can be easily performed.

  Further, the housing has a pair of arm portions, and a cable groove that communicates from the end surface to the storage portion is formed on the indoor side surface of the arm portion so as to communicate with the guide groove of the motor bracket. When the end surface is inclined so as to gradually approach the indoor side as it goes to the storage part (Claim 5), it is easy to draw the inner cable provided on the outdoor side of the motor bracket to the storage part on the indoor side.

  As shown in FIG. 1, the carrier plate 3 is a plate-like member guided by a bent portion of the guide rail 2. The carrier plate 3 is formed with a box-shaped locking portion 3 a for locking the inner cable 13. A cylindrical or disk-shaped cable end 14 formed integrally with the inner cable by casting or the like is accommodated in the end of the inner cable 13 and locked in the box-shaped interior at the locking portion 3a. In this embodiment, a spring 16 for taking the slack of the inner cable 13 is housed between the inner surface of the box-shaped locking portion 3 a and the cable end 14. The spring 16 is preferably a compression coil spring, and is disposed so as to surround the inner cable 13 and the cable end 14. Such a locking portion 3a of the carrier plate 3 and a portion guided by the guide rail 2 may be formed as separate parts and insert-molded into a base made of a steel plate. Further, the material of the portion guided by the guide rail 2 is preferably polyoxymethylene or nylon, particularly polyoxymethylene (POM), in order to improve slidability.

  The pulley 8 is pivotally supported at the upper end of the guide rail 2, and guides the rising inner cable 13a at the outer peripheral edge. On the other hand, the cable guide 9 includes an arc-shaped outer peripheral wall that can change the direction of the lowering inner cable 13b. The cable guide 9 is made of polyoxymethylene (POM) having high slidability. Moreover, it can replace with the cable guide 9 and can also use the pulley 8, and it can replace with the above-mentioned pulley 8 and the cable guide 9 can also be used. However, it is preferable to use the pulley 8 because the rising inner cable 13a has a large load.

  The motor bracket 4 shown in FIG. 4 is made of a plate-shaped member, particularly a metal plate, and is attached to the vicinity of the middle of the guide rail 2 by a fastening member or by welding. The motor bracket 4 extends from the guide rail 2 to the rear side (left side in FIG. 2), and is fixed to the outdoor side surface of the inner panel 31 in the vicinity beyond the opening 31a. A substantially circular communication port 4a is formed in the vicinity of the center of the motor bracket 4, and the housing portion 11 of the housing 6 is inserted into the communication port 4a from the indoor side. The communication port 4a is an elongated hole that is elongated in the direction in which the inner cable 13a for raising and the inner cable 13b for lowering (see FIG. 1) extend continuously from the substantially circular part at the center and the circular part. 4b, 4b. Further, two attachment portions 4c and 4c such as welding nuts are formed on the outer peripheral edge on the rear side of the motor bracket 4, and are fixed to the inner panel 31 with fasteners such as screws. In this embodiment, an elongate mounting seat is provided on the rear outer peripheral edge along the direction in which the rising inner cable 13a and the lowering inner cable 13b (see FIG. 1) extend. A mounting hole 4e for fixing the housing 6 is formed around the communication port 4a.

  The motor 7 includes a motor main body 7a and a speed reducer 7b. A hook-shaped portion extends from the outer periphery of the speed reducer 7b, and a fixing hole 7c for fixing to the housing 6 is formed in the hook-shaped portion. Is formed. In this embodiment, a worm gear reducer is used as the reducer 7b, the worm wheel is arranged concentrically with the drum 5, and the motor body 7a is disposed between the guide rail 2 and the rising inner cable 13a (see FIG. 1). It is arranged. Thereby, space saving of the whole window regulator 1 can be achieved.

  As shown in FIG. 5b, the drum 5 is housed in the housing 6 and then disposed inside the communication port 4a (see FIG. 4). For this reason, the motor bracket 4 is provided with guide grooves 4d and 4d formed by bending in a U-shape or V- or U-shape so that the inner cable 13 wound around the drum 5 does not interfere with the motor bracket 4. Yes. The inner cable 13 is guided to the drum 5 without interfering with the motor bracket 4 by the guide groove 4d. Thereby, it functions as a protector so that the inner cable 13 cannot be seen from the indoor side. Further, the guide groove 4d formed by bending acts as a bead for reinforcing the motor bracket 4 and increases the strength.

  Returning to FIG. 1, the window regulator 1 of the present invention is fixed to the periphery of the opening 31 a at a total of four points including the upper and lower ends of the guide rail 2 and the two mounting portions 4 c and 4 c on the outer periphery of the motor bracket 4. Yes. Therefore, the window regulator 1 has a structure that can uniformly support the load applied by the raising and lowering of the window glass W at the four points, so that the thickness of each member can be reduced and the weight can be reduced. The material of the guide rail 2 and the motor bracket 4 can be SGCC, SPCC, or a metal plate coated and plated with them. The plate thickness of the guide rail 2 can be reduced to about 0.7 to 1.6, preferably about 1.0 to 1.2 mm. Such a guide rail 2 can be efficiently manufactured by bending a metal plate by press working or roll forming. When the inner panel 31 is curved outward so as to follow the shape of the door D, the entire guide rail 2 can be similarly curved (see FIG. 3).

  Moreover, since the window regulator 1 acts as a reinforcing member of the opening 31a (see FIG. 2) of the inner panel 31, the thickness of the inner panel 31 can be reduced. In this embodiment, two attachment portions on the outer periphery of the motor bracket 4 are formed, but the number of attachment portions can be increased or decreased according to the size of the opening 31a. In that case, it is preferable to disperse and arrange the supporting portions so as not to be biased as much as possible.

  Next, the housing 6 will be described with reference to FIGS. 4 and 5a. The housing 6 includes two housing portions 11 for housing the drum 5 and cable grooves 12 a and 12 a extending outward so as to communicate the housing portion 11 with the guide grooves 4 d and 4 d of the motor bracket 4. Arm portions 12 and 12 and a flange portion 10 in which a mounting hole 10a for fixing the housing 6 to the motor bracket is formed.

  A housing space for housing the drum 5 of the housing portion 11 is opened on the indoor side surface of the housing 6, and cable grooves 12 a and 12 a extend along the arm portion 12 so as to communicate with the housing space. Extends and reaches the tip of the arm. A columnar projection 11b is formed on the top surface 11a (see FIG. 5b) of the storage unit 11, and the drum 5 is pivotally supported. Further, the width of the cable grooves 12a, 12a is formed to be larger than the diameter of the inner cable 13, and when the housing 6 is formed of a synthetic resin, it is easy to form. On the other hand, in the portion where the cable grooves 12a, 12a communicate with the storage portion 11, the gap L between the drum 5 and the inner peripheral wall of the storage portion 11 prevents the inner cable 13 from being disturbed by the inner cable 13 coming off the drum 5. Smaller than the diameter of The portion of the inner peripheral wall of the storage portion 11 that forms the gap L is a random winding prevention wall 11c. The housing 6 is preferably made of a material having high slidability in consideration of contact with the drum 5 and the inner cable 13, and particularly preferably POM.

  The storage portion 11 and the arm portion 12 are disposed so as to protrude outward from the circular portion at the center of the communication port 4a of the motor bracket 4 and the long holes 4b and 4b. On the other hand, the collar portion 10 is fixed to the indoor side surface of the motor bracket 4. The arm portions 12 and 12 projecting to the outdoor side are arranged so as to communicate with the guide grooves 4d and 4d of the motor bracket 4, and guide the cable grooves 12a and 12a to the guide grooves 4d and 4d. The end surfaces formed at the distal end portions of the arm portions 12 and 12 are inclined so as to gradually approach the indoor side toward the storage portion 11. The inclined portion is an inclined portion 12b. Further, a claw-shaped protrusion 11d is formed on the outer peripheral surface of the housing portion 11 of the housing 6 (FIG. 5b), and when the housing 6 is inserted into the communication port 4a of the motor bracket 4, it is elastically deformed in the communication port 4a. The housing 6 is temporarily fixed to the motor bracket.

  Next, the procedure for locking the inner cable 13 to the drum 5 will be described with reference to FIG. First, the rising inner cable 13a and the lowering inner cable 13b extending from the pulley 8 and the cable guide 9 (see FIG. 3) extend from the outdoor side of the motor bracket 4 to the indoor side through the elongated holes 4b and 4b. At that time, the cable end 14 (see FIG. 1) provided at the tip of the inner cable 13 is guided to the indoor side of the motor bracket 4 so as to rise upward by the inclined portion 12b formed in the housing 6 (FIG. (See arrow 6). Therefore, it is easy to guide the inner cable 13 from the outdoor side to the indoor side. Next, the guided inner cable 13 is locked to the drum 5.

  Returning to FIG. 4, the procedure for attaching the drum 5, the housing 6 and the motor 7 to the motor bracket 4 will be described. First, the housing portion 11 of the housing 6 is fitted into the communication port 4a from the top surface 11a side from the indoor side surface of the motor bracket 4. When the housing 6 is fitted, the housing 6 is temporarily fixed to the motor bracket 4 by the projections 11 d formed on the outer peripheral surface of the storage portion 11. Next, the drum 5 is inserted into the storage unit 11. Then, the motor 7 is disposed so that the temporarily fixed drum 5 is confined in the storage portion 11, and the rotation shaft of the motor 7 is engaged with the central axis of the drum 5 so as to be sandwiched with the top surface 11 a of the housing 6. In this state, a fastener such as a bolt 15 is inserted from the indoor side of the motor bracket 4 to fasten the motor 7. Thus, since all the members can be assembled from the indoor side, the assembling work is easy. Further, since the inner panel 31 can be disassembled from the indoor side even after the assembly, work efficiency during maintenance is high.

  In the window regulator 1 thus formed, the inner cable 13 is disposed outside the motor bracket 4, and only a necessary portion, that is, a portion locked to the drum 5 is guided from the communication port 4 a to the inside of the storage portion 11. It is burned. Therefore, only a portion that needs waterproofing can be arranged on the indoor side, and a portion where water can enter can be arranged on the outdoor side of the motor bracket 4. Also, since all parts are assembled from one side during assembly, work efficiency is high. Further, when the assembled window regulator 1 is inserted from the opening 31 a of the inner panel 31 and attached to the inner surface of the inner panel 31, most of the inner cable 13 is disposed on the outdoor side by the motor bracket 4. Therefore, the inner cable 13 is not damaged at the outer peripheral edge of the opening 31a.

  FIG. 7 illustrates another embodiment in which the drum 5 is locked to the motor bracket 4. In addition, the same code | symbol is attached | subjected to the same part as the window regulator 1, and the description is abbreviate | omitted. As for the housing 20 shown in FIG. 7, the arm part 12 is not formed. And it attaches to the motor bracket 4 from the outdoor side with the volt | bolt 15, and it latches so that the drum 5 may be pinched | interposed by the top | upper surface 20a and the motor 7. FIG. The housing 6 is provided with a hook-shaped mounting portion 20 b for locking with the motor bracket 4. It is a structure that can be attached to the motor bracket 4 with one attachment by the attachment portion 20b. Therefore, since the structure is simple, the housing can be reduced in size and space is saved.

  In this embodiment, since the guide rail 2 is used as a beam member that reinforces the opening 31a of the inner panel 31, the thickness of the entire door can be reduced by 10 to 20 mm accordingly. Further, the weight of the door can be reduced to 100 to 200 g. Thus, according to the present Example, the space inside the door D can be used effectively or the indoor living space can be enlarged. Also, since there is room in the thickness direction in the hollow interior of the door, it is necessary to widen the indoor space or to provide a large space for installing other equipment such as a speaker protruding from the speaker hole 31c into the hollow portion of the door. Can do.
