[0007] Patent Document 2: Japanese Patent Application Laid-Open No. 2004-175199 Summary of the Invention

[0008] Problems to be solved by the invention

[0009] In the above-mentioned conventional technology, for example, due to the need to mount batteries under the floor, it is sometimes impossible to arrange the lower rails inside the vehicle.

[0010] In this case, as in Patent Document 2, a sliding door structure in which the lower arm itself rotates may be adopted.

[0011] However, in such a structure, if a cable is passed through the underside of the lower arm as in Patent Document 1, the cable may swing as the sliding door opens and closes. Furthermore, as the sliding door opens and closes, the width between the vehicle body and the door changes. Therefore, the excess length of the cable may sag when the door closes, potentially damaging the cable or hindering smooth door opening and closing.

[0012] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a sliding door structure that can smoothly open and close the sliding door even if the lower arm itself rotates, while suppressing damage to the cable.

[0013] Means for solving problems

[0014] The latch mechanism is adapted to engage the latching portion and the latch catch when the sliding door is in the fully opened position, thereby maintaining the sliding door in the fully opened position. The latch mechanism is adapted to engage the latching portion and the latch catch when the sliding door is in the fully opened position. The latch mechanism is adapted to engage the latching portion and the latch catch when the sliding door is in the fully opened position. The latch mechanism is adapted to engage the latching portion and the latch catch when the sliding door is in the fully opened position.

[0015] In the above structure, the second component is characterized in that it is composed of a link mechanism.

[0016] In the structure, it is characterized in that the link mechanism is constructed to include: a rod, one end of which is connected to the latch portion and is arranged along the lower arm in the direction of the sliding door; and a rotating body, which is connected to the other end of the rod and can rotate around the rotation axis.

[0017] In the structure, it is characterized in that the rotating body has a pushing piece on the side opposite to the rod across its rotation center, the first component has a cable and a cable action component that moves according to the movement of the cable, and the pushing piece and the cable action component are arranged in close positions when the sliding door is in the fully open position.

[0018] Effects of the Invention

[0019] According to the present invention, the full-open latch component is composed of a first component on the sliding door side relative to the rotation axis of the lower arm and a second component on the vehicle body side. Therefore, even if the lower arm rotates along with the opening and closing of the door, the first component and the second component will not twist around the rotation axis, which can suppress damage to the first component and the second component and enable smooth opening and closing of the front door and the rear door.

Figure 7 This is a perspective view showing a state in which the rear engaging hole and the engaging protrusion of the reinforcing bracket of the sliding door structure in the present embodiment are engaged. Figure 8 This is a perspective view of the lower arm in this embodiment as seen from below.

[0078] like Figures 2 to 8 As shown, a side member 10 extending in the front-rear direction of the vehicle body 2 is provided at the lower end of the opening of the vehicle body 2. A front lower rail 11 and a rear lower rail 12 are provided on the upper surface side of the side member 10 so as to follow the side member 10.

[0079] A reinforcement bracket 13 is provided between the rear end portion of the front lower rail 11 and the front end portion of the rear lower rail 12 .

[0080] The reinforcement bracket 13 is formed into a hollow box shape and has vertically upright walls 14 around it. A flange 15 extending outward from the vehicle body 2 is integrally formed at the lower edge of the reinforcement bracket 13 .

[0081] Furthermore, the reinforcement bracket 13 includes a front support surface 16 and a rear support surface 17 at both ends in the front-rear direction, which are inclined relative to the front-rear direction of the vehicle body 2. The front support surface 16 and the rear support surface 17 are formed so that the direction perpendicular to the front support surface 16 and the direction perpendicular to the rear support surface 17 intersect on the inner side of the vehicle body 2.

[0082] A front engaging hole 18 and a rear engaging hole 19 , each having a substantially quadrilateral shape and serving as an engaged portion, are formed on the front supporting surface 16 and the rear supporting surface 17 , respectively.

[0083] The reinforcement bracket 13 includes a recessed portion 20 formed by recessing a standing wall portion 14 located on the outer side of the vehicle body 2 in a substantially central portion in the front-rear direction toward the vehicle interior.

[0084] A lock 21 for engaging a latch mechanism of the front door 5 described later is provided at a position of the side member 10 corresponding to the recess 20 of the reinforcement bracket 13. The flange 15 of the reinforcement bracket 13 and the lock 21 are fastened to the side member 10 via bolts 22.

[0085] like Figure 4 As shown, the front lower rail 11 and the upper surface of the reinforcement bracket 13 are connected via a front lower rail bracket 30 .

[0086] A support plate 31 that curves downward along the front support surface 16 is integrally formed with the front lower rail bracket 30. A front hole portion (not shown) having substantially the same shape as the front engagement hole 18 is formed at a position of the support plate 31 corresponding to the front engagement hole 18 of the reinforcement bracket 13.

[0087] A cushioning member 33 made of, for example, a resin material is provided around the front hole.

[0088] In addition, if Figure 5 As shown, similarly, the upper surface of the rear lower rail 12 and the reinforcement bracket 13 are connected via the rear lower rail bracket 34. Figure 5 As shown, a support plate 35 that is bent downwardly along the rear support surface 17 is integrally formed on the rear lower rail bracket 34. A rear hole portion (not shown) having substantially the same shape as the rear engagement hole 19 is formed at a position of the support plate 35 that corresponds to the rear engagement hole 19 of the reinforcement bracket 13.

[0089] A cushioning member 33 made of, for example, a resin material is provided around the rear hole.

[0090] like Figure 5 As shown in FIG. 1 , a reinforcement member 36 is attached to the upper surface of the reinforcement bracket 13. A stepped portion 37 is formed on the interior side of the vehicle body 2 of the reinforcement member 36 so as to protrude upward.

[0091] A space is formed between the lower surface of the step-shaped portion 37 and the upper surface of the reinforcing bracket 13. This space serves as a support space into which a support piece 43 of a hook member 42 described later is inserted.

[0092] Next, the structure of the sliding door will be described.

[0093] like Figure 2 and Figure 3 As shown, a lower arm 40 is attached to the lower portion of the front door 5 so as to protrude toward the interior side of the vehicle body 2 .

[0094] A sliding door bracket 41 is mounted on the lower portion of the front door 5, and a hook member 42 is mounted on the sliding door bracket 41. The hook member 42 is formed into a substantially L-shape, with its lower end extending toward the vehicle interior. The protruding portion of the hook member 42 serves as a support piece 43, which is inserted into the space formed in the stepped portion 37 of the reinforcement member 36.

[0095] The lower arm 40 is rotatably attached to the lower end portion of the hook member 42 .

[0096] A lower roller 48 is rotatably mounted on a distal end portion of the lower arm 40 . The lower roller 48 engages with the front lower rail 11 and is guided along the front lower rail 11 .

[0097] An engaging protrusion 44 serving as an engaging portion that protrudes obliquely from one side and engages with the front engaging hole 18 is provided in a midway portion of the lower arm 40 .

[0098] The engaging protrusion 44 includes a protrusion portion 45 that is inserted into and engaged with the front engaging hole 18 , and a base portion 46 that extends toward both sides at a base end portion of the protrusion portion 45 .

[0099] A fully closing latch member 47 is attached near the base end portion of the lower arm 40 . When the front door 5 is fully closed, the fully closing latch member 47 engages with the striker 21 to hold the front door 5 in a closed state.

[0100] Furthermore, a full-open latch member 50 is attached to the lower surface of the front lower rail 11 . The full-open latch member 50 holds the front door 5 in an open state when the front door 5 is fully opened.

[0101] In addition, if Figure 7 As shown, the rear door 6 is also attached to a lower arm 40 , and the lower arm 40 is provided with an engaging protrusion 44 as an engaging portion that engages with the rear engaging hole 19 of the reinforcement bracket 13 .

[0102] Next, the full-open latch member 50 will be described.

[0103] Furthermore, the fully opening latch member 50 has the same structure in the front door 5 and the rear door 6 .

[0104] Figure 9 This is a perspective view of the lower arm 40 portion as viewed from below. Figure 10 It is a three-dimensional diagram of the rotating body.

[0105] like Figure 9As shown, the full-open latch member 50 includes a rotating member 51 rotatably mounted on the lower arm 40 via a rotating shaft 53. A latch claw 52 serving as a latch portion is provided at the distal end of the rotating member 51 and engages with a full-open striker (not shown) when the front door 5 is fully opened.

[0106] One end of a rod 54 provided along the lower arm 40 is provided on a side portion of the rotating shaft 53 of the rotating member 51 on the opposite side from the latch claw 52 .

[0107] Furthermore, a rotating body 55 is provided at the attachment portion of the hook member to the lower arm 40. The rotating body 55 is coaxially attached to the rotating shaft 49 that rotatably supports the lower arm 40.

[0108] Two protruding members 56 protruding substantially in the radial direction are provided on the outer periphery of the rotating body 55 . One protruding member 56 is connected to the other end of the rod 54 .

[0109] And, in Figure 9 When the rotating body 55 rotates in the clockwise direction, the rotating member 51 rotates in the clockwise direction via the rod 54, and the latch claw 52 rotates in the clockwise direction. By rotating the latch claw 52 in the clockwise direction, the engagement between the full-opening lock catch and the latch claw 52 is released.

[0110] A push piece 57 is formed at the distal end of the other protruding member 56. The push piece 57 is formed in an arc shape by bending the distal end about a substantially horizontal axis.

[0111] The rotating member 51, the rod 54 and the rotating body 55 constitute the connecting rod mechanism of the second member of the present invention.

[0112] like Figure 7 as well as Figure 10 As shown, a cable support member 60 is provided near the upper portion of the rotation shaft 49. The cable support member 60 is connected to one end of a cable 61. The other end of the cable 61 is connected to a door handle (not shown), and the cable 61 is pulled by operating the door handle.

[0113] One end of a cable actuating member 62 is attached to the cable supporting member 60. The cable actuating member 62 is formed in a substantially L-shape and is attached to the lower arm 40 so as to be rotatable around a corner thereof.

[0114] A cylindrical pushing portion 63 extending in the axial direction of the rotation shaft 49 is provided at the other end of the cable actuating member 62 .

[0115] The cable 61 , the cable support member 60 , and the cable actuating member 62 constitute the first member of the present invention.

[0116] Figure 10 The rear door 6 is shown in a fully closed state. In this state, the push piece 57 of the rotating body 55 is separated from the push portion 63 of the cable actuating member 62. Furthermore, when the rear door 6 is fully opened, the lower arm 40 rotates about the rotation axis as the rear door 6 opens, thereby placing the push piece 57 of the rotating body 55 and the push portion 63 of the cable actuating member 62 in close proximity.

[0117] Next, the operation of this embodiment based on such a configuration will be described.

[0118] In the present embodiment, when the front door 5 is closed, the front door 5 moves in the closing direction while the lower roller 48 of the front door 5 is guided by the front lower rail 11 .

[0119] Then, the rear end portion of the front door 5 moves toward the vehicle body 2 while being guided by the front lower rail 11 , and the front door 5 is closed.

[0120] When the front door 5 is fully closed, the engaging protrusion 44 provided on the lower arm 40 is inserted into the front engaging hole 18 of the reinforcing bracket 13 .

[0121] In addition, the rear door 6 also moves while the lower roller 48 of the lower arm 40 is guided by the rear lower rail 12. When the rear door 6 is fully closed, the engaging protrusion 44 provided on the lower arm 40 is inserted into the rear engaging hole 19 of the reinforcing bracket 13.

[0122] When the front door 5 or the rear door 6 is opened to the fully open state, the latch claw 52 of the fully open latch member 50 engages with the fully open striker to hold the front door 5 or the rear door 6 in the fully open state.

[0123] When the front door 5 or the rear door 6 is closed, the cable 61 is pulled by operating the door handle, thereby causing the cable operating member 62 to move through the cable supporting member 60. Figure 10 Rotate in clockwise direction.

[0124] By the rotation of the cable actuating member 62 , the pushing portion 63 pushes the pushing piece 57 of the rotating body 55 , and the rotating body 55 rotates in the clockwise direction.

[0125] In this case, the pusher 63 is formed into a cylindrical shape extending in the axial direction of the rotating shaft, and the pusher piece 57 is formed into an arc shape on a substantially horizontal axis. Therefore, the pusher 63 and the pusher piece 57 abut each other with a curved surface. Therefore, the contact resistance can be reduced, and damage to the pusher 63 or the pusher piece 57 can be suppressed.

[0126] Furthermore, the curved surface of the pushing portion 63 abuts against the curved surface of the pushing piece 57 while intersecting at approximately 90°. Therefore, the force generated by the rotation of the cable actuation member 62 can be reliably transmitted to the pushing piece 57 .

[0127] And, in Figure 9 When the rotating body 55 rotates in the clockwise direction, the rotating member 51 rotates in the clockwise direction via the rod 54, and the latch claw 52 rotates in the clockwise direction. By rotating the latch claw 52 in the clockwise direction, the engagement between the full-opening lock and the latch claw 52 is released, and the closing operation can be performed.

[0128] As described above, in this embodiment, the fully-open latch component 50 includes a fully-open latch component that causes the latch claw 52 (latch portion) to move to an engaged position or an unengaged position relative to the lock buckle, and the portion of the fully-open latch component 50 that is closer to the sliding door side than the rotating shaft 49 is composed of a first component, and the portion of the fully-open latch component 50 that is closer to the vehicle body side than the rotating shaft 49 is composed of a second component that is moved by the first component.

[0129] Thus, the full-open latch component 50 is composed of a first component on the sliding door side relative to the rotating shaft 49 of the lower arm 40 and a second component on the vehicle body side. Therefore, even if the lower arm 40 rotates along with the opening and closing of the door, the first component and the second component will not twist around the rotating shaft, which can suppress damage to the first component and the second component and enable smooth opening and closing of the front door 5 and the rear door 6.

[0130] Furthermore, in this embodiment, the second member is composed of a link mechanism.

[0131] Thus, the second member that actuates the fully-opening latch member 50 is a link mechanism, and when the latch portion is actuated to the engaged position or the disengaged position relative to the lock catch, no excess length is generated as in the conventional cable 61. Therefore, the front door 5 and the rear door 6 can be opened and closed smoothly.

[0132] In addition, in this embodiment, the connecting rod mechanism is constructed to include: a rod 54, one end of which is connected to the latch claw 52 (latch part) and is arranged along the lower arm 40 in the direction of the front door 5 and the rear door 6; and a rotating body 55, which is connected to the other end of the rod 54 and can rotate around the rotating shaft 49.

[0133] As a result, the rotating shaft 49 of the lower arm 40 is made identical to the rotation center of the rotating body 55 of the connecting rod mechanism. Therefore, the fully opening latch component can be operated with high precision in coordination with the movement of the lower arm 40, the number of components can be further reduced, and space can be saved around the lower arm 40.

[0134] In addition, in this embodiment, the rotating body 55 has a pushing piece 57 on the side opposite to the rod 54 separated by its rotation center, and the first component has a cable 61 and a cable action component 62 that moves according to the movement of the cable, and the pushing piece 57 and the cable action component 62 are arranged in close positions when the sliding door is in the fully open position.

[0135] Thus, the push piece 57 and the cable operating member 62 are arranged close to each other in the fully opened position. Therefore, the movement of the cable 61 is not transmitted to the rotating body 55 except in the fully opened position of the front door 5 and the rear door 6. Therefore, the latch part does not move excessively except in the fully opened position of the front door 5 and the rear door 6, and no operating noise is generated.

[0136] As mentioned above, although embodiment of this invention was described, various design changes can be made to this invention within the range which does not deviate from the summary.

[0137] In the above embodiment, the case where both the front door 5 and the rear door 6 are sliding doors has been described as an example. However, the present invention is also applicable to a case where only the front door 5 or the rear door 6 is a sliding door.
