Abstract

<P>PROBLEM TO BE SOLVED: To smoothly open and close a door of a car body even by either of a swing slide mode or a swing mode. <P>SOLUTION: A striker 50 has an inclined part 52 slantingly extending in the separating direction of a rotary latch 55 from the tip of a leg part 51a. When opening the door of the car body in the swing slide mode, since the rotary latch 55 separates via the inclined part 52 of the stroker 50, even when the rotary latch 55 reaches up to the tip of the leg part 51a without rotating only up to a half latch position since a moving speed of the door is fast, the rotary latch can be further rotated up to an unlatching position by the inclined part 52. Since the leg part 51a extends on a plane orthogonal to a latch shaft 56 of the rotary latch 55, when closing the door of the car body in the swing mode, the rotary latch 55 engages from the leg part 51a, and rotation of the rotary latch 55 is not interfered with the inclined part 52. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a vehicle door opening / closing structure that supports a door attached to an opening of a vehicle body in an openable / closable manner.

  A vehicle such as an automobile is provided with a door for opening and closing an opening for getting on and off the vehicle. The door is supported by the vehicle body by an opening / closing structure and can be freely opened and closed. When the door is closed to the fully closed position, the door is held by the vehicle body by a door lock mechanism. This door lock mechanism is of a type in which a rotatable latch (hereinafter referred to as “rotation latch”) is provided at the end of the door, and the rotation latch is rotationally engaged with a striker fixed to the opening end of the vehicle body. It has been known.

  On the other hand, the door opening / closing structure includes a swing type in which the door is rocked via a hinge and a slide type in which the door is slid along the side surface of the vehicle body. When a swing-type opening / closing structure is adopted, the number of parts can be reduced and the structure can be simplified. However, since the door overhang is large, it is difficult to open / close the door in a narrow parking lot. There is a case. On the other hand, when the sliding opening / closing structure is adopted, it is possible to reduce the amount of overhang of the door and facilitate the opening / closing operation of the door in a narrow parking lot or the like. There is a problem that is easily influenced by the situation. Therefore, it has two open / close modes, a slide mode that opens and closes in a sliding manner and a swing mode that opens and closes in a swing manner, and has both the advantages of both the slide and swing types, and according to the usage environment and the operator's intention. A swing-sliding open / close structure that can be used properly has been proposed.

  In addition, in the swing / sliding type opening / closing structure, in order to suppress the influence of the slide rail on the vehicle body structure, the door is slid in the vehicle front-rear direction and the four-bar linkage mechanism that translates the door inward and outward of the vehicle body An open / close structure has been developed in which a slide mechanism that moves in a separate manner is provided separately.

  In this opening / closing mechanism, when the door is opened and closed in the swing mode, the movement trajectory of the door end has a large turning radius around the hinge axis of the door, but the door provided with a four-bar linkage mechanism and a sliding mechanism With this open / close structure, when the door is opened in the swing / slide mode, the movement trajectory of the door end when the door is once pulled out to the outside of the vehicle body is a small rotation around the swing axis of the four-bar linkage mechanism The radius. In other words, when opening in the swing / slide mode, the radius of movement of the door end near the door closing end becomes smaller than when opening in the swing mode. On the other hand, the striker is formed in a substantially U-shape composed of a pair of leg portions and a connecting portion for connecting the leg portion, and the rotation latch is engaged with and disengaged from the one leg portion. The boundary portion between and is formed in a shape close to a right angle. Further, the rotation latch is always urged in the unlatching direction by the urging force of the spring, and when the ratchet restraining force provided in the vicinity of the rotation latch is applied, each rotation position of the half latch position or the full latch position of the rotation latch is applied. The position can be held. For this reason, when the moving speed of the door is high when the door is opened from the fully closed state, the end surface of the rotating latch comes into contact with the inner side of the striker leg before the rotating latch is returned to the unlatched position. In some cases, the force to open the door may cause a frictional resistance to stop the rotation of the rotary latch and prevent the door from opening.

Therefore, for example, as shown in FIG. 12, a door lock mechanism 60 has been proposed in which a latch engaging portion 62a of a striker 62 serving as a front end edge on the door 61 entry side is disposed substantially perpendicular to the door entry locus I ( Patent Document 1). According to the door lock mechanism 60, it is possible to optimize the degree of engagement between the latch engagement portion 62a of the striker 62 and the striker engagement portion 63a of the rotation latch 63 and prevent the rotation latch from being caught.

  However, since the proposal of the above-mentioned patent document 1 inclines the striker in accordance with the intrusion direction of the rotary latch, and has a dedicated swing / slide type configuration, if the same configuration is applied to the swing type, the intrusion of the rotary latch into the striker Since the direction changes, it cannot function normally, and it becomes difficult to apply to a door opening / closing structure having two opening / closing modes of swing / slide mode and swing mode.

  On the other hand, in the door opening / closing structure having the above two opening / closing modes, in order to allow the rotation latch and the striker to be shared normally in each opening / closing mode, the thickness of the striker is reduced, or the striker leg is It is possible to make it longer. It is also conceivable to provide a striker with a drive device such as a motor and to extend and retract the striker in accordance with the position of the rotary latch. However, if the thickness of the striker is reduced, there is a problem that the rigidity is lowered. If the length of the leg portion of the striker is increased, the striker may come into contact with a door lock mechanism provided with a rotation latch. In addition, if the striker is provided with a driving device, the structure becomes complicated and there is a problem of cost increase.

  An object of the present invention is to smoothly open and close a door of a vehicle body in both a swing / slide mode and a swing mode.

In other words, the first connecting arm 27 and the second connecting arm 30 connect the vehicle body 11 and the slider 26 to form a four-bar linkage mechanism 33. The door 12 can be pulled out from the fully closed position in the vehicle outward direction, that is, in parallel to the outside of the vehicle body. Further, by moving the slider 26 along the slide rail 25 while the front door 12 is pulled out of the vehicle body 11, the front door 12 can be moved in the vehicle longitudinal direction along the vehicle body 11. . A pair of support arms 34a and 34b are connected between the front door 12 and the base member 21, and the weight of the front door 12 is supported by these support arms 34a and 34b.

  As shown in FIGS. 3 and 4, a control arm 35 for controlling the opening / closing operation of the front door 12 is provided at the tip of the second connecting arm 30 disposed on the vehicle interior side on the slider 26 side. A guide rail 36 for controlling the control arm 35 is fixed to the base plate 24.

  The control arm 35 is formed shorter than the second connection arm 30 and is formed integrally with the second connection arm 30 at the base end portion thereof. The axial direction is orthogonal to the axial direction of the second connecting arm 30. That is, the second connecting arm 30 is formed in an L shape in which the control arm 35 is integrally provided. As a result, the control arm 35 is rotatably supported by the slider 26 by the pin member 29 together with the second connecting arm 30. On the other hand, the guide rail 36 includes a straight portion 36a extending in the vehicle front-rear direction parallel to the slide rail 25, and a curved portion 36b that is continuous with the straight portion 36a and bends with respect to the straight portion 36a.

The closed cable 43b is connected to the slider 26 from the front side of the vehicle via a reversing pulley 44b. Accordingly, when the electric motor 41 is operated and the open cable 43a is wound around the drum 42, the slider 26 is pulled by the open cable 43a and moves toward the stroke end of the slide rail 25 on the vehicle rear side. At this time, the closed cable 43b is fed out from the groove portion as the drum 42 rotates. On the contrary, when the electric motor 41 rotates in the reverse direction and the closed cable 43b is wound around the drum 42, the slider 26 is pulled by the closed cable 43b and moves toward the stroke end of the slide rail 25 on the vehicle front side. At this time, the open-side cable 43a is fed out from the groove as the drum 42 rotates.

  The electric motor 41 is connected to a control unit (not shown) having a CPU, a memory and the like. When an opening / closing switch (not shown) provided in the driver's seat is operated, the electric motor 41 is operated by the control unit according to the operation signal. The operation of is controlled.

  Next, the opening / closing operation | movement of the front door 12 by this opening / closing structure 20 is demonstrated based on FIGS. FIGS. 5A to 5C are perspective views showing the opening / closing operation of the front door 12 in the swing / slide mode, and FIGS. 6A to 6D are explanations showing the operating state of the opening / closing structure 20 in the swing / slide mode. FIGS. 7A to 7C are perspective views showing details of the operation state of the four-bar linkage mechanism 33 in the swing / slide mode, and FIGS. 8A and 8B are operations of the opening / closing structure 20 in the swing mode. It is explanatory drawing which shows a state.

  The opening / closing structure 20 can be switched between a swing / slide mode and a swing mode under the control of the first lock mechanism 23a and the front door lock mechanism 23b, and the first lock mechanism 23a is in a fastening state. The open / close structure 20 is set to the swing / slide mode, and the front door 12 is opened and closed by the four-bar linkage mechanism 33. In addition, when the lock mechanism 23 is released, the front door lock mechanism 23b is engaged, and the opening / closing structure 20 is set to the swing mode so that the front door 12 can swing together with the base member 21. .

  Next, the opening / closing operation of the swing / sliding door opening / closing structure of the present embodiment will be described. First, the opening / closing operation | movement of the front door 12 in swing mode is demonstrated.

  When the front door 12 is in the fully closed position as shown in FIG. 5 (a), the slider 26 is positioned at the stroke end of the slide rail 25 on the vehicle front side as shown in FIGS. 6 (a) and 7 (a). The engaging pin 37 of the control arm 35 is positioned at the tip of the curved portion 36b of the guide rail 36 and is not engaged with the guide rail 36.

  From this state, when the front door lock mechanism 23b is released while the first lock mechanism 23a is locked, the slide actuator 40 is activated and pulled by the open cable 43a, and the slider 26 moves along the slide rail 25 in the vehicle. When the movement is started toward the rear stroke end, a driving force directed toward the vehicle front side is applied to the front door 12 by the traction force of the open cable 43a. Accordingly, as shown in FIG. 6B, the front door 12 is guided by the four-bar linkage mechanism 33 and starts moving in parallel toward the outside of the vehicle body 11.

  Next, when the front door 12 opens more than a predetermined opening, the engagement pin 37 of the control arm 35 is engaged with the curved portion 36b of the guide rail 36 as shown in FIG. Thus, the opening / closing operation of the front door 12 is controlled. That is, when the slider 26 moves, the engaging pin 37 of the control arm 35 moves along the curved portion 36b as the slider 26 moves, and the control arm 35 turns about the pin member 31. The link mechanism 33 is operated and the front door 12 is pulled out in a swinging direction toward the outside of the vehicle. Then, as shown in FIGS. 6C and 7C, when the front door 12 is opened to the position where the connecting arms 27 and 30 are orthogonal to the axial direction of the slide rail 25, the engaging pin 37 is bent. The rotation of the control arm 35 stops from the part 36b to the straight part 36a. The movement trajectory of the end portion of the front door 12 at this time is a small radius of rotation about the swing axis of the substantially four-bar linkage mechanism 33 relative to the base member 21.

  Next, when the slider 26 further moves along the slide rail 25, the engagement pin 37 of the control arm 35 is guided to the straight portion 36a of the guide rail 36, and as shown in FIG. 11 slidably moves along the outside of the vehicle 11, and when the slider 26 moves along the slide rail 25 to the stroke end on the vehicle rear side, the operation of the slider 26 stops and the front door 12 stops at the fully open position. To do. In these series of operations, the support arms 34 a and 34 b that support the weight of the front door 12 follow the opening and closing operation of the front door 12 without hindering the opening and closing operation of the front door 12. As described above, in the opening / closing structure 20, the opening / closing operation of the front door 12 is performed continuously from the fully closed position to the outside of the vehicle body and the sliding operation in the vehicle longitudinal direction after being pulled out. The operation can be smoothed and the vehicle quality can be improved.

  Next, the opening / closing operation of the front door 12 in the swing mode will be described. As shown in FIG. 8A, the slider 26 stops on the slide rail 25 at the stroke end on the fully closed side, and the front door lock mechanism 23b is locked while the front door 12 is in the fully closed position. When the first locking mechanism 23a is released in this state, the base member 21 can swing about the opening / closing central axis of the hinge shaft 22 with respect to the vehicle body 11. As a result, as shown in FIG. 8B, the front door 12 can be manually opened and closed in a swing manner. At this time, since the front door lock mechanism 23b is locked, the four-bar linkage mechanism 33 does not operate, and the front door 12 opens and closes integrally with the base member 21 in a swing manner. At this time, the movement trajectory of the end portion of the front door 12 has a large turning radius around the hinge shaft 22 of the door.

  6 and 8, in the opening / closing structure 20, a striker 50 is provided on the vehicle body 11 side between the vehicle rear end of the front door 12 and the vehicle body 11, and the striker 50 is provided on the front door 12 side. A rear door lock device 54 having a rotation latch 55 that engages with the rear door lock device 54 is provided. 6 and 8, the structure and reference numerals of the rotary latch are omitted.

  FIG. 9 is a plan view of the striker 50, and FIGS. 10A to 10E are explanatory views showing the operating state of the striker 50 and the rotation latch 55 in the swing / slide mode. FIGS. c) is an explanatory view showing an operating state of the striker 50 and the rotation latch 55 in the swing mode. 10 and 11, the diagrams on the left side are diagrams showing the rotation state of the rotation latch 55 corresponding to the diagrams on the right side.

  As shown in FIGS. 9 and 10, the striker 50 includes a pair of leg portions 51 a and 51 b, an inclined portion 52, and a connecting portion 53. The pair of leg portions 51a, 51b is on a plane orthogonal to the latch shaft (rotation shaft) 56 of the rotation latch 55 and extends in parallel with the longitudinal direction of the vehicle body, and the leg portion 51a on the side engaged with the rotation latch 55 rotates. It is formed shorter than the leg portion 51b on the side not engaged with the latch 55. The inclined part 52 extends in a direction away from the latch shaft 56 of the rotation latch 55 from the tip of the leg 51a, that is, in the direction of the tip of the leg 51b. The boundary portion between the leg portion 51a and the inclined portion 52 is chamfered and formed in an arc shape, and the radius of curvature of the inner side a is smaller than that of the outer side b. The connecting portion 53 extends from the tip of the leg portion 51b to the tip of the inclined portion 52 at a right angle to connect the two. The striker 50 is formed by bending or casting a bar.

  On the other hand, as shown in FIG. 10, a latch groove 55a is formed on the outer periphery of the rotation latch 55, and the striker 50 is provided so as to be detachable from the rotation latch 55 by the latch groove 55a. A latch shaft 56 is provided at the shaft center of the rotation latch 55, and the rotation latch 55 is rotatable between the full latch position and the unlatching position around the latch shaft 56. Further, the leg portions 51 a and 51 b of the striker 50 described above are provided so as to be parallel in a plane orthogonal to the latch shaft 56.

  Next, the operation of the striker 50 and the rotation latch 55 in the swing / slide mode will be described with reference to FIG. First, as shown in FIG. 10A, when the front door 12 is in the fully closed position, the rotation latch 55 is in the full latch position, and the leg portion 51a of the striker 50 is fitted into and abuts the latch groove 55a. ing. The rotation latch 55 is always urged in the unlatching direction by an urging force of a return spring (not shown), and when a restraining force of a ratchet (not shown) provided close to the rotation latch 55 is applied, the half latch of the rotation latch 55 is actuated. Each rotational position of the position and the full latch position can be held. When the front door 12 starts to move parallel to the outside of the vehicle body 11 by the four-bar linkage mechanism 33 from this state, when the moving speed of the front door 12 is fast, as shown in FIG. 55 moves to the tip of the leg 51a while rotating only to the half latch position.

  When the front door 12 is further pulled out of the vehicle body 11 from this state, a part of the rotation latch 55 moves to the inclined portion 52 of the striker 50 and is rotated by the inclined portion 52 as shown in FIG. , And in combination with the biasing force of the return spring, it rotates from the half latch position toward the unlatch position. Then, as shown in FIG. 10D, the rotation latch 55 is rotated to the unlatched position by the urging force of the return spring until it reaches the inclined portion 52 completely. Finally, as shown in FIG. 10 (e), the rotation latch 55 is separated from the inclined portion 52 as the front door 12 is pulled out. As a result, the striker 50 comes out of the latch groove 55a. The engagement state is released. When the front door 12 is pulled into the vehicle body 11, the rotation latch 55 is engaged by the inclined portion 52 and operates in the reverse order as described above.

  That is, when the pair of leg portions 51a and 51b are formed to have the same length and are directly connected by the connecting portion 53 without providing the inclined portion 52 in the striker 50, the boundary portion between the leg portion 51a and the connecting portion 53 becomes a right angle. Close shape. Further, since the rotation latch 55 is always urged in the unlatching direction by the urging force of the return spring, it automatically rotates to the unlatched position by the urging force of the return spring when the restraining force of the ratchet is released. However, the rotation radius of the movement locus of the end portion of the front door 12 in the swing / slide mode is small, and the base end direction of the rotation latch 55 and the opening direction of the front door 12 are shifted as shown in FIG. . For this reason, if the moving speed of the front door 12 is slow, the rotary latch 55 is returned to the unlatched position by the urging force of the return spring before reaching the tip of the leg 51a, so that it can be detached from the leg 51a. If the moving speed is high, the end surface of the rotation latch 55 may come into contact with the leg 51a of the striker 50 or the inner side of the connecting portion 53 before the rotation latch 55 is returned to the unlatched position, and the front door 12 is opened. The force to be tried may become a frictional resistance that stops the rotation of the rotation latch 55 further, and the front door 12 may not be opened. Therefore, for example, when the vehicle body 11 is inclined, the front door 12 may not be smoothly opened when the moving speed of the front door 12 must be increased. On the other hand, if the striker 50 is provided with the inclined portion 52, the rotation latch 55 rotates at the inclined portion 52 even when the rotation latch 55 reaches the tip of the leg portion 51 a while rotating only to the half latch position. , And in combination with the urging force of the return spring, it rotates from the half latch position toward the unlatch position, so that the end surface of the rotation latch 55 is not caught by the striker 50 and the front door 12 is opened without being affected by the moving speed. It becomes possible.

  Next, the operation of the striker 50 and the rotation latch 55 in the swing mode will be described with reference to FIG. First, the front door lock mechanism 23b is fastened to release the first door lock mechanism 23a, and when the front door 12 is pulled into the vehicle body 11 in a state where the front door 12 can swing together with the base member 21, First, as shown in FIG. 11A, the rotation latch 55 is engaged with the leg 51a at the unlatched position, and guides the striker 50 into the latch groove 55a. Next, as shown in FIG. 11B, the rotation latch 55 rotates in the direction of the full latch position against the urging force of the return spring while moving in the direction in which the front door 12 is closed. Then, as shown in FIG. 11 (c), while further moving in the closing direction of the front door 12, it rotates to the full latch position, and the rotation is finished in a state where the leg 51a is drawn into and brought into contact with the latch groove 55a. . As described above, when the front door 12 is swung together with the base member 21, the rotation latch 55 engages with the leg portion 51 a of the striker 50, so that the rotation is not interfered by the inclined portion 52 and the front door 12 is smoothly closed. It becomes possible to make it. Further, as shown in FIG. 9, since the radius of curvature of the inner side “a” is smaller than the outer side “b” at the boundary portion between the leg portion 51 a and the inclined portion 52, the rotation latch 55 slightly contacts with and comes into contact with the inclined portion 52. Even in such a case, a force is applied in the closing direction of the front door 12, and the inclined portion 52 does not interfere with the rotation of the rotation latch 55 to the full latch position.
