Description

  The present invention relates to a vehicle door opening / closing device for driving a slide door of a vehicle and a method of mounting the same.

  Rear doors in one-box cars, wagons and vans are often provided with sliding slide doors, and in recent years their opening and closing operations have been automated. As a general configuration of a vehicle door opening and closing apparatus for automatically opening and closing a slide door, a rail member provided along the side of the body and a wire for opening and closing the door through an arm by being driven along the rail member And the drive part which drives a wire is provided (for example, refer patent document 1, patent document 2).

  In order to stably open and close the slide door, it is preferable to support the slide door at three points, the upper rail, the center rail and the lower rail. By providing the drive unit on the center rail, the foot space of the rear seat can be enlarged, or the freedom in layout for mounting other devices can be increased.

  When attaching the vehicle door opening and closing device to a vehicle, there is a concern that the wire may be damaged or the wire itself may be damaged before the wire is pulled around and connected to the arm, so care must be taken in handling. In addition, the drive unit for driving the wire has a large size because the mechanism for applying tension to the wire is included. Therefore, it has also been proposed to use a belt which does not require a complicated tension mechanism instead of a wire (see, for example, Patent Document 3). Further, the rail member is made of stainless steel or painted in the case of a steel material in view of the rustproof performance.

The mounting seat 26 is formed of a vertical surface that conforms to the peripheral shape of the insertion hole 116, and is curved in plan view. The mounting seat 26 has holes 26a at the four corners. The two front holes 26a penetrate substantially in the front-rear direction, and the two rear holes 26a substantially penetrate in the vehicle width direction. A seal 46 sandwiched between the quarter panel 20 and the inner surface of the mounting seat 26 is provided. The seal 46 is a waterproof and dustproof material and is formed in a rectangular ring shape with four corners.

  The front guide portion 42a includes a slightly short rear linear portion 48 and a curved portion 50 that continuously curves inward in the vehicle width direction from the front of the linear portion 48, and the curved portion 34 of the rail 16b in plan view It has a shape along with it. The front guide portion 42 a has an upper plate 52, a lower plate 54, and a guide plate 56 provided so as to extend from the straight portion 48 to the curved portion 50. The guide plate 56 connects the upper plate 52 and the lower plate 54, forms a smooth surface from the linear portion 48 to the curved portion 50, and exerts the guiding action of the belt 40.

  The front guide portion 42 a further has a timing pulley 60 provided at the front end of the bending portion 50 and a hinge bracket 62 provided coaxially rotatably with the timing pulley 60.

  The timing pulley 60 is rotatably provided by the upper plate 52 and the lower plate 54 in a direction in which the rotation axis is in the vertical direction. The timing pulley 60 turns the belt 40 at the front end of the belt guide 24. That is, the belt 40 is turned 180 ° via the timing pulley 60 to move between the front side position and the back side position of the guide plate 56.

  Further, the front guide portion 42 a has a finisher fixing portion 64 and a plate mounting seat 66 which are provided side by side on the upper surface of the upper plate 52 in the straight portion 48. The finisher fixing portion 64 is one of the fixing portions of the finisher 17 (see FIG. 2). The finisher fixing portion 64 is provided in a range surrounded by the mounting seat 26 in the mounting direction of the finisher 17. An inner portion of the finisher fixing portion 64 is connected to the mounting seat 26. An L-shaped protection plate 67 is attached to the plate attachment seat 66. The protective plate 67 protects the belt guide portion 24 against external force from the side surface.

  The rear guide portion 42b is slightly longer than the front guide portion 42a, and has a linear shape along the long portion 32 of the rail 16b in a plan view. The rear guide portion 42 b has an upper plate 72, a lower plate 74, and a guide plate 76. The upper plate 72, the lower plate 74, and the guide plate 76 correspond to the upper plate 52, the lower plate 54, and the guide plate 56 of the front guide portion 42a.

  The rear guide portion 42 b further includes a stopper rib 80, a pulley holder 84, and a timing pulley 86. The stopper rib 80 is provided on the upper surface near the front end of the upper plate 72 and on the lower surface near the front end of the lower plate 74. The pulley holder 84 is provided at the rear end of the rear guide portion 42b. The timing pulley 86 is rotatably held by a pulley holder 84 about a vertical axis. The timing pulley 86 turns the belt 40 at the rear end of the belt guide 24. That is, the belt 40 is turned 180 ° via the timing pulley 86 to move between the front side position and the back side position of the guide plate 76.

  The guide plates 56 and 76, the upper plates 52 and 72, and the lower plates 54 and 74 are base frames formed in the belt guide portion 24 along the rails 16b, and other hinge brackets 62 and pulley holders 84 are provided. And holds pulleys. The guide plates 56 and 76, the upper plates 52 and 72, and the lower plates 54 and 74, which are base frame bodies, are large parts but are formed of resin materials 45a, 45b and 45c and are lightweight. The rail 16b is generally made of metal from the viewpoint of strength to support the door 14, but the belt guide portion 24 is separate from the rail 16b, so that resinification is possible. Further, since the belt guide portion 24 is made of resin separately from the rail 16b, the configuration divided into the front guide portion 42a and the rear guide portion 42b is easily realized, and the advancing / retreating of the rear guide portion 42b It is easy to realize the configuration of the rotation mechanism.

  The drive portion 27 projects obliquely backward from the inner side surface of the mounting seat 26 and projects into the vehicle compartment from the insertion hole 116 (see FIG. 14) of the quarter panel 20, and as described above, the motor 28; It has a bypass portion 29 and a gear portion 30.

  As shown in FIG. 5, the motor 28 has a cylindrical shape, and includes a yoke 28a, a front gear portion 28b, an output shaft 28c, and a connector 28d. The rotation of the yoke 28a is decelerated by the planetary gear mechanism in the front gear portion 28b and transmitted to the coaxial output shaft 28c. The connector 28d is a receptacle type and is provided on the side surface of the front gear portion 28b. Although the front gear portion 28b constitutes a reduction mechanism together with the rear gear portion 30, it is an integral part of the yoke 28a and the connector 28d, and therefore is a part of the motor 28 for the convenience of description.

  A small diameter bevel gear 28e is provided at the tip of the output shaft 28c, and is inserted into the obliquely forward gear portion 30. The motor 28 is rotationally controlled by a controller 138 (see FIG. 17) connected via the connector 28d. A regenerative brake is set to the motor 28, and a clutch and a torque limiter are unnecessary. Further, the motor 28 may be of a silent type.

  The gear portion 30 is configured around a common vertical shaft 110 with the detour portion 29 and has a small diameter bevel gear 28 e and a large diameter bevel gear 112. The small diameter bevel gear 28e is a pinion gear and is provided on the output shaft 28c of the motor 28 as described above. The large diameter bevel gear 112 is fixed to the upper portion of the vertical shaft 110, and teeth are provided along the outer periphery of the lower surface. The small diameter bevel gear 28e meshes with the teeth on the lower surface of the large diameter bevel gear 112, and together with the front gear portion 28b, forms a reduction mechanism to obtain a sufficient reduction ratio. While the small diameter bevel gear 28e is made of metal, the large diameter bevel gear 112 meshing with it is made of resin, and the generation of sound from the meshing surface is reduced.

  The detouring portion 29 is a portion for detouring a part of the belt 40 from the belt guide portion 24 into the vehicle interior, and has a timing pulley 29a and two guide pulleys 29b and 29c. The timing pulley 29 a is fixed to the lower part of the vertical shaft 110 and rotates integrally with the vertical shaft 110 and the large diameter bevel gear 112. The vertical shaft 110 is pivotally supported at its upper end and lower end by a bearing 110a (however, illustration is omitted on the lower end side). A gear coupling 110 b is provided between the large diameter bevel gear 112 and the timing pulley 29 a.

  The front side guide pulley 29b and the rear side guide pulley 29c are arranged substantially in the front-rear direction, and are rotatably provided by the resin materials 45a and 45b in the direction in which the rotation axis is in the vertical direction. The guide pulleys 29b and 29c are provided on the front and back of the timing pulley 29a via a belt 40, and guide the belt 40 so as to be wound about 260 degrees with respect to the timing pulley 29a. As a result, the driving force of the timing pulley 29a is sufficiently transmitted to the belt 40, and it circulates in both forward and reverse directions.

  Belt 40 is U-turned by timing pulleys 60 and 86 at the front and back ends of belt guide portion 24. Also, the belt 40 detours from between between the two guide pulleys 29 b and 29 c to the timing pulley 29 a in the detour 29 at the inner side of the circulation path. Furthermore, the belt 40 is guided in an arc shape by the guide plate 56 at the curved portion 50 at the outer side of the circulation path. Thus, the belt 40 is rotationally driven by the belt guide portion 24, and the belt connector 44 fixed to the belt 40 can reciprocate along the outer surface from the front end to the rear end.

  As shown in FIG. 6, the drive portion 27 is connected to the curved portion 50 in the front guide portion 42a, and by taking such a connection form, the drive portion 27 projects obliquely backward to the vehicle interior side. The protrusion amount is suppressed and the indoor space is hardly reduced.

  Further, in plan view, the rotational axis of the motor 28 is set to an angle θ of 15 ° to the vehicle interior side with respect to the direction from the bending portion 50 to the rear, that is, the X2 direction. It is preferable that the angle θ be set in the range of 0 ° to 30 °. By connecting the drive portion 27 in accordance with the curved portion 50, the rotation axis of the motor 28 can be set within this angular range, whereby the protrusion of the yoke 28a in the vehicle width direction can be suppressed. In particular, when the yoke 28a is disposed within the width W of the center rail 16b in the vehicle width direction, the entire structure becomes compact and there is almost no protrusion to the vehicle interior side.

  Further, in plan view, the center-to-center distance L2 between the rear guide pulley 29c and the timing pulley 29a is set smaller than the center-to-center distance L1 between the front guide pulley 29b and the timing pulley 29a. As a result, the angle θ can be easily reduced, and the protrusion of the yoke 28 a in the vehicle width direction can be further suppressed.

  As shown in FIG. 7, at the rear end portion of the guide plate 56 in the front guide portion 42a, two long hole posts (convex portions) 68a and 70a which project inward and are juxtaposed in the front-rear direction are provided. The long hole post 68a is in the vicinity of the rear end of the guide plate 56, and the long hole post 70a is provided slightly forward thereof. The long hole post 70a is slightly longer than the long hole post 68a, and a bolt hole 70c is provided at the center.

  The front end portion of the guide plate 76 in the rear guide portion 42b is provided with two long holes (fitting holes) 68b and 70b penetrating in the vehicle width direction and juxtaposed in the front-rear direction. The long hole 70 b is in the vicinity of the front end of the guide plate 76, and the long hole 68 b is provided slightly behind it. The lower protruding portion 26 b of the mounting seat 26 protrudes downward by h from the lower surface of the lower plate 54.

  As shown in FIG. 8, the long hole post 68 a is inserted into the long hole 68 b, and both form a fitting mechanism 68. The long hole post 70 a is inserted into the long hole 70 b, and both form a fitting mechanism 70. The long hole post 68 a has substantially the same length as the thickness of the guide plate 76. The long hole post 70 a is longer than the thickness of the guide plate 76 and slightly protrudes inward from the inner surface of the guide plate 76. The width in the vertical direction of the long holes 68 b and 70 b is a size such that the long hole posts 68 a and 70 a can be fitted with almost no gap. The width in the front-rear direction of the long holes 68b and 70b is slightly longer than the long hole posts 68a and 70a.

  Further, the bolt 91 is screwed into the bolt hole 70 c of the long hole post 70 a via the washer (retaining portion) 90. The washer 90 is fixed in the form of a flange at the end of the long hole post 70a. The provision of the washer 90 prevents the long hole post 70a from coming out of the long hole 70b, and allows the operator to handle the front guide portion 42a and the rear guide portion 42b in an integrated manner.

  A gap 93 is formed between the guide plate 76 and the washer 90. The front end portion of the rear guide portion 42b is displaceable in the vehicle width direction within the range of the gap 93, so the rear guide portion 42b is slightly in a horizontal plane centering on the rear end portion 56a (see FIG. 6) of the guide plate 56. It is possible to rotate (see the phantom line in FIG. 6). That is, the rear guide portion 42b can be advanced and retracted in the front-rear direction with respect to the front guide portion 42a of the connection partner by the two sets of fitting mechanisms 68 and 70 provided on the front and rear sides, and can be rotated. There is. The two sets of fitting mechanisms 68, 70 have a simple structure, are easy to assemble, and are inexpensive to manufacture. Since the fitting mechanism 68 and the fitting mechanism 70 are provided slightly apart in the front-rear direction, the rear guide portion 42b can prevent forward and backward movement of the front-rear direction and prevent the rear guide portion 42b from rotating on the vertical surface. Since the front end portion of the rear guide portion 42b is sandwiched by the upper plate 52 and the lower plate 54 of the front guide portion 42a, the advancing and retracting operation is further stabilized.

  The washer 90 has the function of preventing the long hole post 70a from coming off as described above, but also functions as a rotation limiter of the rear guide portion 42b. The long hole post 68a closer to the rotation center (rear end 56a) than the long hole post 70a may be set slightly longer to provide the washer 90 on the long hole post 68a. When provided on the hole post 70a, the angular accuracy as a rotation limiter is high, and the working pressure is small and stable.

  The stopper rib 80 prevents the rear guide portion 42b from approaching the front guide portion 42a excessively, and secures the strength at this portion. Further, within the range of the clearance between the stopper rib 80 and the rear end of the upper plate 52 and the lower plate 54, the rear guide portion 42b can be advanced and retracted with respect to the front guide portion 42a. The moving allowance for advancing and retreating is set to a necessary and sufficient length, and the rear guide portion 42 b is moved forward excessively in the mounting process of the vehicle door opening and closing device 10 and unnecessary slack is not generated in the belt 40 . The gap in the longitudinal direction with respect to the long hole posts 68a and 70a in the long holes 68b and 70b is set larger than the gap between the stopper rib 80 and the rear end of the upper plate 52 and the lower plate 54. The guide plate 76 of the rear guide portion 42 b is disposed slightly inside the guide plate 56 of the front guide portion 42 a and does not contact the belt 40. Thereby, the resistance when driving the belt 40 can be reduced.

  As shown in FIG. 9, the hinge bracket 62 is coaxial with the timing pulley 60 at the tip of the front guide portion 42a and is rotatably provided. The hinge bracket 62 is a rectangle whose cross section is open on one side, and has a side plate 62a, a bolt hole 62b, an upper plate 62c, and a lower plate 62d. The bolt hole 62b is provided at the center of the side plate 62a. The upper plate 62c is connected from the upper side of the side plate 62a. The lower plate 62d is connected from the lower side of the side plate 62a. The upper plate 62c is partially sandwiched between the upper plate 52 of the front guide portion 42a and the upper surface of the timing pulley 60, and the lower plate 62d is partially formed of the lower plate 54 of the front guide portion 42a and the lower surface of the timing pulley 60. It is supported by each in between. In this manner, the hinge bracket 62 is rotatable coaxially and independently with the timing pulley 60. A small claw 42c is provided at the tip of the front guide portion 42a. The claw 42c functions as a stopper that restricts rotation by abutting on a part of the upper plate 62c. The hinge bracket 62 can tolerate an angular error of the mounting surface on the vehicle side and is easy to fix. Further, the hinge bracket 62 has a coaxial structure with the timing pulley 60, so that the hinge structure can be realized rationally and easily.

  As shown in FIGS. 10 and 11, the pulley holder 84 is provided at the end of the rear guide portion 42b, and holds the timing pulley 86 rotatably about the vertical axis. The rear guide portion 42 b has upper and lower claws 92 provided at the end portions of the upper plate 72 and the lower plate 74 and a block body 94 connecting the upper plate 72 and the lower plate 74 at the connecting portion with the pulley holder 84.

The belt 40 omitted in FIGS. 10 and 11 is wound around the timing pulley 86 and passes between the half cylinder plate 84a. The pulley holder 84 can be fixed at one touch by engaging the two claws 92 with the claw holes 84 e by pressing the rear end portion of the rear guide portion 42 b forward. At the connection portion between the rear guide portion 42 b and the pulley holder 84, the block 84 f abuts on the upper and lower surfaces of the block 94 to be stabilized.

  The pulley holder 84 further has an engagement piece 86g at the rear end. The engagement piece 86g is U-shaped in a plan view, the U-shaped bottom portion is directed inward, and one end is connected to the half cylinder plate 84a. A claw 86h is provided on the side surface of the engagement piece 86g. The engagement piece 86 g is a member fixed to a fixing bracket 96 provided on the quarter panel 20.

  The fixing bracket 96 includes an inner plate 96a, an upper plate 96b connected from the upper side of the inner plate 96a, a lower plate 96c connected from the lower side, and a rear plate 96d connected from the rear side. Lower ribs 96e project in opposite directions from the front ends of the upper plate 96b and the lower plate 96c, respectively. The upper plate 96 b is provided with a notch 96 f for avoiding interference with the shaft of the timing pulley 86. The rear plate 96d is not connected to the upper plate 96b and the lower plate 96c, and a nail hole 96g is provided at the center.

  By pressing the pulley holder 84 against the fixing bracket 96, the claw 86h engages with the claw hole 96g and can be fixed at one touch. In the fixing bracket 96, the upper plate 96b and the lower plate 96c abut on the upper and lower surfaces of the pulley holder 84, and the rib 96e abuts on the entire surface of the engaged piece 84d to make the pulley holder 84 in all directions. Keep it stable. The fixing bracket 96 may be fixed to the top rear end of the rail 16b.

  The engagement structure between the claw 92 and the claw hole 84e and the engagement structure between the claw 86h and the claw hole 96g are so-called snap fit, and the structure provided on one of the parts is not limited to the illustrated structure. It is sufficient if it has a structure in which the other recess is fitted and hooked using the.

  As shown in FIG. 12, the belt connector 44 is connected to the belt 40, and the meshing portion 100 meshed with and fixed to the teeth of the belt 40, and the meshing portion 100 and the arm 22 (see FIG. 2). And a connecting portion 102 connecting the two.

  The meshing portion 100 includes a biting plywood 100a, an upper plate 100b connected from an upper side of the biting plywood 100a, and an engagement piece 100c protruding from a lower side. The biting plywood 100a has five ridges 100d slightly higher than the width of the belt 40 and extending in the vertical direction, and four valleys 100e formed between the ridges 100d. Engage with 4 teeth. The biting plywood 100a is formed by, for example, pressing. Two bolt holes 100f are provided in parallel in the upper plate 100b. The engagement piece 100c has an angled cross section, and its tip is directed downward.

  The connecting portion 102 includes, in order from the top, a fastening piece 102a, a belt gripping piece 102b, a bending piece 102c, and an arm connection piece 102d. The fastening piece 102a is horizontal, and two bolt holes 102e are provided in parallel. By screwing a bolt into the bolt hole 100 f and the bolt hole 102 e, the upper plate 100 b and the fastening piece 102 a are fastened. The belt gripping piece 102b is a vertical member for gripping the belt 40 together with the biting plywood 100a, and has a long rectangular engaging hole 102f with which the engaging piece 100c is engaged. The bending piece 102c is a member that is slightly long in the vertical direction, and connects the belt gripping piece 102b and the arm connection piece 102d while bending in two steps at a loose angle. The arm connection piece 102 d is a slightly elongated member, and a bolt is screwed into two bolt holes 102 g arranged in parallel to be connected to the arm 22.

  In the belt connector 44 configured as described above, the ridges 100 d and the valleys 100 e of the biting plywood 100 a mesh with the teeth of the belt 40 so that they are securely fixed to the belt 40. Further, it is the four teeth of the belt 40 that the biting plywood 100a is engaged, so that sufficient fixed strength can be obtained and the width in the front-rear direction can be narrowed. By narrowing the width of the belt connector 44 in the front-rear direction, the opening degree of the door 14 can be increased accordingly.

  The number of teeth of the belt 40 with which the biting plywood 100a is engaged is desirably four teeth or three teeth in view of narrowing the width of the belt connector 44 and fixed strength.

  As shown in FIG. 13, the belt 40 has a shape in which peak portions 40 a and valley portions 40 b extending in the width direction (height direction based on the vehicle 12) on the tooth surface side are alternately arranged, A tooth cloth 40c, a tooth rubber layer 40d, a plurality of core wires 40e, and a back rubber layer 40f are provided. The tooth cloth 40c is provided on the tooth surface. The tooth rubber layer 40d forms a peak portion 40a and a valley portion 40b. The plurality of core wires 40 e are provided around the tooth rubber layer 40 d and wound in the circumferential direction. The back rubber layer 40f is provided on the outside of the tooth rubber layer 40d via the core wire 40e. The mountain portion 40a corresponds to a tooth. A shallow recess 40g extending in the width direction is provided at the top of the peak 40a. The tooth cloth 40c is a nylon cloth which has been lubricated. The core wire 40e is made of glass fiber. The tooth rubber layer 40d and the back rubber layer 40f are chloroprene rubber.

  In the belt 40, sufficient tensile strength can be obtained by the core wire 40e, and further, sufficient tooth surface strength can be obtained by the tooth cloth 40c. In addition, the provision of the recessed portion 40g causes the peak portion 40a to be elastically deformed according to the shape of the other valley portion to be meshed and to be reliably meshed, and the valley portion 40b also contact the other peak portion without any gap. Can. The belts 40 are preferable because they do not easily get scratched with each other even when contacting with other devices when the vehicle door opening and closing device 10 is assembled. Further, unlike the iron wire, the belt 40 is free from rusting and no treatment such as application of grease is required. The belt 40 is incorporated in the belt guide portion 24 in advance, and the work of drawing is unnecessary.

  The belt 40 is manufactured, for example, as follows. First, the tooth cloth 40c which is sewn in a cylindrical shape is wound around a cylindrical mold provided with an axial tooth mold on the outer peripheral surface. The core wire 40e is wound in a spiral shape with a narrow interval around it. Furthermore, after chloroprene rubber is wound around it, it is heated, pressurized and vulcanized to plasticize the chloroprene rubber, leach out a part from the interstices of the core wire 40e, and press the tooth cloth 40c against the mold tooth surface A mountain portion 40a and a valley portion 40b are formed. The portion exuded from the gap of the core wire 40e becomes a tooth rubber layer 40d, and the outside portion of the core wire 40e becomes a back rubber layer 40f. The molded body thus obtained is removed from the mold and cut into round slices to obtain a belt 40.

  The vehicle door opening and closing device 10 configured as described above is formed of a relatively large component such as the front guide portion 42a, the rear guide portion 42b, the mounting seat 26 and the like, and is light in weight as a whole. The vehicle door opening and closing device 10 and the rail 16b are separately configured, and each of them is light in weight and excellent in portability. Since the vehicle door opening and closing device 10 is combined with the center rail 16b, the lower rail 16c does not have a drive portion, and the rear seat foot space is enlarged or the layout freedom for mounting other devices is increased. There is no impact on the strength of the platform floor and no reinforcement is required.

  Next, the quarter panel 20 to which the vehicle door opening and closing device 10 is attached will be described, and further, a method of attaching the vehicle door opening and closing device 10 to the quarter panel 20 will be described with reference to FIGS.

  As shown in FIG. 14, the quarter panel 20 has a tire house 21, a filler opening 18, a rear end section 113, and a rail mounting recess 114. The door rear end section 113 is a section that supports and supports the rear end side when the door 14 is closed.

  The rail mounting recess 114 is a recess to which the rail 16 b and the belt guide portion 24 are attached, which is provided between the fuel inlet 18 and the tire house 21 and extends in the front-rear direction of the vehicle 12. It curves toward the vehicle interior along the end section 113. The rail mounting recess 114 has an insertion hole 116, a plurality of rail mounting holes 118, and a plurality of posts 120. Further, the rail mounting recess 114 can be divided into a linear long surface 114b that extends in the front-rear direction at the rear and a curved surface 114a that curves continuously in the vehicle width direction from the front of the long surface 114b. The curved surface 114a is a portion to which the curved portion 34 of the rail 16b and the curved portion 50 of the front guide portion 42a are attached. The long surface 114b is a portion to which the long portion 32 of the rail 16b, the straight portion 48 of the front guide portion 42a, and the rear guide portion 42b are attached.

  The insertion hole 116 is a rectangular hole into which the drive portion 27 is inserted, and is provided on the curved surface 114 a between the striker 117 and the bending portion 34. The striker 117 is a member engaged with the lock portion of the door 14 to hold the door 14 in the closed state. In a vehicle 12 having a sliding door 14, the striker 117 is generally provided to project forward at a section rear surface 113 a in the rear end section 113 of the door. The section rear surface 113a is a generally vertical surface (Y-Z plane) in the front-rear direction, and it is rational and preferable to provide the insertion hole 116 below the striker 117 at the section rear surface 113a. The post 120 is a fixing portion to which the finisher 17 is attached.

  The height width of the insertion hole 116 is set to be larger than the height of the drive portion 27 by h (see FIG. 7) or more. In the vicinity of the four corners of the insertion hole 116, bolt holes 121 are provided. Among them, the front two are provided indoors than the insertion hole 116, and the rear two are provided rearward than the insertion hole 116. That is, all the four bolt holes 121 are provided on the side of the insertion hole 116, the required width in the vertical direction is small, and the mounting seat 26 and the rail mounting recess 114 can be set narrow.

  A curved surface 114a which is a front portion of the rail mounting recess 114 forms a curved surface corresponding to the curved portion 34 of the rail 16b. A fixing bracket 96 is provided in the vicinity of the rear end of the rail mounting recess 114. A bolt hole 122 is provided in the vicinity of the front end of the curved surface 114a.

  In the method for attaching the vehicle door opening and closing device 10 to the quarter panel 20, first, as shown in FIG. 14, the rail 16b is attached to the rail attachment recess 114 (rail attachment step). The rail 16 b is fixed by bolting the mounting hole 38 and the rail mounting hole 118. The upper surface of the attached rail 16b and the lower side 116a of the insertion hole 116 have substantially the same height.

  Next, the rails 16b are painted in the same color together with the quarter panel 20 (rail painting step). As a result, the rails 16b and the quarter panel 20 can be completely the same color, and the appearance is improved. Also, the rail 16b can be omitted at least for finish painting up to this point. The rails 16b are already mounted in the rail mounting recess 114, and are not transported alone by the operator after this, and there is no risk of damage or peeling off of the coating. Therefore, it is hard to rust even if it uses inexpensive steel instead of expensive stainless steel. In addition, since the vehicle door opening and closing device 10 is not attached to the rail attachment recess 114 at this time, the paint does not adhere to the belt 40 and the pulleys.

  Thereafter, the vehicle door opening and closing device 10 is attached to the rail attachment recess 114 (main body attachment step). In this step, first, as shown in FIG. 14, the entire vehicle door opening and closing device 10 is moved so that the drive unit 27 is inserted into the insertion hole 116. At this time, the direction in which the vehicle door opening and closing device 10 is moved is backward or diagonally backward according to the size and direction of the drive portion 27 and the insertion hole 116, but is adjusted to the angle θ (see FIG. 6) of the axial center of the motor 28. The drive portion 27 is easily inserted into the insertion hole 116 when it is moved.

  As shown in FIG. 15 (a), the lower projecting portion 26b of the mounting seat 26 is allowed to pass above the rail 16b, and the driving portion 27 is inserted into the insertion hole 116 to project into the vehicle interior. At this time, a gap 126 is secured between the upper indoor side surface 124 of the rail 16 b and the surface of the rail mounting recess 114. The depth of the gap 126 is slightly larger than h. Then, as shown by the white arrows, the detour portion 29 and the mounting seat 26 are lowered downward or obliquely downward along the surface of the rail mounting recess 114.

  As shown in FIG. 15 (b), when the lower protruding portion 26b of the mounting seat 26 enters the gap 126, the upper indoor side surface 124 serves as a retainer for the lower protruding portion 26b. In particular, the gap 126 is provided along the curved portion 34 of the rail 16b, and the lower protruding portion 26b is provided along the curved portion 50 of the front guide portion 42a to correspond to this. The reference numeral 26b acts as a retaining member in both the front-rear direction and the vehicle width direction, and the belt guide portion 24 is stabilized. Further, the lower surface of the lower plate 54 abuts on the upper surface of the rail 16 b. Thereby, as shown in FIG. 16, the belt guide portion 24 is stably and temporarily placed on the upper surface of the rail 16b, and does not fall even if the operator releases the hand, and the positional deviation is also almost not Absent. Furthermore, since the lower projecting portion 26b overlaps the rail 16b in a side view, the mounting seat 26 is disposed downward accordingly, and the height width of the rail mounting recess 114 and the finisher 17 can be narrowed. it can. Further, in the development of the vehicle 12, the design freedom and the design freedom of the quarter panel 20 are improved.

  As shown in FIG. 16, when inserting the drive portion 27 rearward into the insertion hole 116, the rear guide portion 42b is slightly rotated clockwise in plan view with respect to the front guide portion 42a. The pulley holder 84 at the rear end is retracted outward to a position where it does not interfere with the fixing bracket 96. Thereafter, the rear guide portion 42b is rotated counterclockwise in a plan view with respect to the front guide portion 42a, and the pulley holder 84 at the rear end is displaced toward the indoor side and inserted into the fixing bracket 96 The rear end of the portion 24 is fixed (see FIGS. 2 and 10). At this time, an easy operation is possible by a snap fit in which the claw 86h of the engagement piece 86g (see FIG. 10) is engaged with the claw hole 96g. The snap fit by the claw 86 h and the claw hole 96 g is an engagement structure in the vehicle width direction, and a displacement margin in the height direction is unnecessary at this portion, and the height width of the rail mounting recess 114 may be set narrow. it can. Further, since the vehicle door opening and closing device 10 is a separate structure from the rail 16b, it is lightweight and easy for the operator to handle. The vehicle door opening and closing device 10 is a belt type without wire, and can prevent contact with the surroundings due to wire routing.

  The action of the rear guide portion 42b is to change the direction of the belt 40 by the timing pulley 86 at the rear end, and no other large load is applied. Further, the timing pulley 86 is held by the pulley holder 84, and the pulley holder 84 is fixed to the rail mounting recess 114 via the fixing bracket 96 and is stable. Therefore, the rear guide portion 42b may not be fixed to the rail mounting recess 114 at any other place, and bolt fastening is not necessary.

  Next, a bolt is screwed in from the bolt hole 62 b of the hinge bracket 62 and fastened to the bolt hole 122. Thus, the belt guide portion 24 is fixed to the rail mounting recess 114. By the way, although the separation distance between the bolt hole 122 to which the front end of the belt guide portion 24 is fixed and the fixing bracket 96 to which the rear end is fixed may have some variations due to manufacturing errors, as shown in FIGS. Since the long hole posts 68a and 70a are inserted into the long holes 68b and 70b, the rear guide portion 42b is connected to be able to move forward and backward with respect to the front guide portion 42a. Can be absorbed. The order of the fixing operation of the rear end of the belt guide portion 24 by the pulley holder 84 and the fixing bracket 96 and the fixing operation of the front end of the belt guide portion 24 by the hinge bracket 62 does not matter.

  Further, as shown in FIG. 2, the finisher 17 is attached to the rail attachment recess 114. The finisher 17 is fixed to the plurality of posts 120 of the rail mounting recess 114 and the finisher fixing portion 64 of the mounting seat 26. The mounting seat 26 occupies a certain area, and the post 120 can not be provided in this part, but as described above, the finisher fixing portion 64 is provided within the range surrounded by the mounting seat 26 in the mounting direction of the finisher 17 By using the finisher fixing portion 64 as one of the posts 120, the finisher 17 can be fixed in many places without bias. Further, the finisher fixing portion 64 is connected to the mounting seat 26 at the back and is fixed to the rail mounting recess 114 by the four holes 26 a via the mounting seat 26, so that the finisher 17 can be reliably made. It can support. In addition, since the belt guide portion 24 is covered by the finisher 17, there is no need to particularly coat it.

  As shown in FIG. 17, bolts are screwed into the four bolt holes 121 and holes 26 a from the vehicle interior to fix the mounting seat 26 to the rail mounting recess 114. A seal 46 is interposed between the mounting seat 26 and the rail mounting recess 114 to achieve waterproofing and dustproofing. In this manner, the separately configured rail 16b and the vehicle door opening and closing device 10 are individually attached to the rail attachment recess 114 respectively.

  The tire house 21 and the fuel pipe cover 128 are bulging out on the indoor side surface of the quarter panel 20. The fuel pipe cover 128 covers the fuel pipe communicating with the fuel tank from the fuel supply port 18, and gradually bulges downward from the portion of the fuel supply port 18, and the lower part thereof is connected to the upper part of the tire house 21.

  A seat belt retractor 132 for winding the seat belt 130 is attached to the inner surface of the quarter panel 20 by a lower anchor 134 at a position slightly above the tire house 21 and in front of the fuel pipe cover 128. Many recent vehicles inside and outside of Japan employ a three-point seat belt for the rear seat, and a corresponding seat belt retractor 132 is often provided at this position. A speaker 136 for audio is provided on the diagonally upper front of the seat belt retractor 132. A controller 138 for controlling the vehicle door opening / closing device 10 is provided at the lower corner of the quarter panel 20 in front of the lower end of the tire house 21.

  As understood from FIG. 17, in a side view, the drive unit 27 of the vehicle door opening and closing device 10 is disposed in a space 140 surrounded by the seat belt retractor 132, the fuel pipe cover 128 and the tire house 21. That is, it is a space 140 in the upper part in the front half of the tire house 21, in the front part in the lower part of the fuel pipe cover 128 and under the seat belt retractor 132. As described above, the drive unit 27 can be disposed in the relatively narrow space 140 because the dimensions in the vehicle width direction and the height direction are reduced.

  Further, by disposing the drive portion 27 in the space 140, a layout without interference with other devices is possible, and the amount of protrusion of the drive portion 27 to the vehicle interior side can be suppressed. The tire house 21, the fuel pipe cover 128 and the seat belt retractor 132 are in the usual arrangement and hardly affected by the layout due to the presence of the drive unit 27.

  The indoor side of the quarter panel 20 is covered by a not-shown interior panel in which only the speaker 136 is meshed except for the window 142. Since the protrusion of the drive unit 27 to the indoor side is suppressed, it is not necessary to provide an unnatural bulging also in the portion covering the drive unit 27 of the interior panel. Although FIG. 17 is a perspective view so that a three-dimensional positional relationship can be grasped, the state of the side view will be clearly understood from FIG.

  The vehicle door opening and closing device 10 is attached to the quarter panel 20 at only five bolt holes 121 and four bolt holes 122 with respect to bolting, which are close to the opening of the door 14 and workability It is located in a good place.

  In the above example, the vehicle door opening and closing device 10 is applied to the left side of the vehicle 12 provided with the fuel inlet 18, but a symmetrical device may be used for the right side. The vehicle door opening and closing device 10 is not limited to the opening and closing of the rear side door 14, and may be applied to, for example, a door of a two-door car.

  The rails 16b are painted after being attached to the vehicle 12, but may be prepainted, rustproofed, or otherwise pretreated if necessary. The rails 16b may be formed of stainless steel, carbon, aluminum, resin or the like according to design conditions.

  The rail 16b and the belt guide portion 24 may be partially fixed directly, or, for example, the fixing bracket 96 may be provided directly on the upper end of the rear end of the rail 16b. The belt guide portion 24 may be attached later than the rail 16b.

  The long holes 68b and 70b into which the long hole posts 68a and 70a are inserted do not necessarily have to be long hole shapes, and it is sufficient if the width in the front-rear direction is longer than the long hole posts 68a. You may be responsible for The two elongated holes 68 b and the elongated holes 70 b may be replaced by one elongated hole having an envelope shape that encloses them in a side view. In this case, the long hole posts 68a and 70a may be substituted by one convex portion having an envelope shape that encloses them in a side view. The two sets of fitting mechanisms 68 and 70 are not limited to the above-described form, and a convex portion protruding in the vehicle width direction from either one of the front guide portion 42a and the rear guide portion 42b is provided on the other, and the convex portion is fitted It may be formed by the mating fitting hole. The structure which makes the back guide part 42b rotatable with respect to the front guide part 42a is not limited to said form, For example, you may provide a vertical axis of rotation. The configuration in which the rear guide portion 42b can be advanced and retracted with respect to the front guide portion 42a is not limited to the above embodiment, and for example, a fitting mechanism in the longitudinal direction may be provided.

  The present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be freely modified without departing from the scope of the present invention.
