Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the sliding door drive mechanism described in Patent Document 1 had the following problems. First, because the cable baffle is provided as a separate component, installation is complicated and the number of parts increases. Second, because there is a gap between the rear window trim and the guide rail, the internal sheet metal structure can be observed through this gap in the front view, and the existence of the gap itself affects the appearance of the vehicle. Furthermore, since all the door opening and closing cables move below the guide rail, the door hinge connected to the cable bracket interferes with the rear window trim during door opening and closing, and after prolonged operation, this may cause deformation, wear and dirt on the rear window trim, affecting the appearance of the vehicle.

[0005] The object of the present invention is to provide a sliding door drive mechanism that can improve the appearance, durability, and ease of installation of a vehicle. [Means for solving the problem]

[0006] A sliding door drive mechanism according to one technical proposal of the present invention is for driving a sliding door to open and close, and comprises a guide rail having a front pulley case at the front and a rear pulley case at the rear, a hinge having one end connected to the sliding door and the other end having a load roller, a closing cable connected to the hinge at a closing cable terminal and guided by a front pulley provided in the front pulley case, an opening cable connected to the hinge at an opening cable terminal and guided by a rear pulley provided in the rear pulley case, and a connector connected to the opening cable and the closing cable, and the opening cable or the closing cable The sliding door is driven to open and close the sliding door by a motor which drives the load roller to slide back and forth along the sliding surface of the guide rail, the guide rail includes a baffle which extends below the sliding surface, the closing cable terminal is positioned in the vertical direction such that when moved by the closing cable the closing cable moves along the baffle, and the opening cable terminal is positioned in the vertical direction such that when moved by the opening cable the opening cable slides in the space above the sliding surface on the guide rail.

[0007] According to this proposed technology, the guide rail is equipped with a baffle that extends below the sliding surface, and the door closing cable terminal is positioned in the vertical direction such that when moved by the door closing cable, the door closing cable moves along the baffle, the door opening cable moves in the space located above the sliding surface on the guide rail, and the door closing cable moves below the guide rail along the baffle. In other words, the guide rail equipped with the baffle also serves as the cable baffle for the door closing cable, eliminating the need to separately create a door closing cable baffle and reducing the number of parts.

[0008] In the above technical proposal, it is preferable that the baffle is formed by bending the guide rail.

[0009] This allows the baffle to be formed by bending the plate material that forms the guide rail, eliminating the need for additional parts or installation work, reducing the number of parts, and improving ease of installation.

[0010] In the above proposed technology, it is preferable that a rubber strip is fixed to the baffle, the rubber strip is provided with a pair of position-retaining ribs extending in the longitudinal direction of the rubber strip, and the door closing cable moves along the rubber strip between the pair of position-retaining ribs.

[0011] As a result, when the sliding door is closed when viewed from the side of the vehicle, the opening cable is positioned within the guide rail and is blocked. When the sliding door is open, the closing cable is exposed outside the rubber strip, but is blocked by the sliding door itself, so it does not affect the appearance of the vehicle. In addition, a simple structure of a pair of position limiting ribs effectively guides the movement of the closing cable along the rubber strip. Furthermore, the hinge is positioned outside the rubber strip in the vehicle width direction and does not directly contact the rubber strip, preventing deformation or excessive wear of the rubber strip. Moreover, the rubber strip also serves as a cable baffle for the closing cable, reducing the number of parts.

[0012] In the above proposed technology, the rubber strip preferably comprises a fixing portion having a recess formed therein for fixing the rubber strip to the baffle when the baffle is inserted, and an extension portion extending from the lower end of the fixing portion until it contacts the vehicle body sheet metal, and the door closing cable preferably moves along the outer surface of the fixing portion.

[0013] This allows the rubber strip to be attached to the baffle in a simple manner, and because the rubber strip extends until it contacts the vehicle's sheet metal, there is no gap between the rubber strip and the guide rail when viewed from the side of the vehicle, making the internal sheet metal structure invisible and improving the appearance.

[0014] In the above proposed technology, it is preferable that a guide bracket is provided in front of the rubber strip, fixed below the guide rail, and that the guide bracket has an opening through which the door closing cable enters and exits, and that the door closing cable moves along the rubber strip after passing through the opening.

[0015] As a result, by positioning the guide bracket in front of the rubber strip, the closing cable that bypasses the front pulley case can be effectively guided to the rubber strip, and wear on the tip of the rubber strip caused by the closing cable is suppressed.

[0016] In the above proposed technology, it is preferable that the guide bracket is provided with a locking portion, the guide rail is provided with a locked portion, and the guide bracket is fixed to the guide rail by the locking of the locking portion and the locked portion.

[0017] This allows the guide bracket to be secured to the guide rail using a snap-fit ​​mechanism, making it easy and convenient to operate, and also allowing the guide bracket to be attached to the cable and delivered together with the product.

[0018] In the above-described technical proposal, it is preferable that the part of the guide bracket that comes into contact with the door closing cable has a recess for storing grease.

[0019] This design, which includes a recess in the guide bracket, allows grease to be applied to the recess during maintenance, making operation easier and reducing wear on the rubber strip.

[0020] In the above proposed technology, it is preferable that a housing space is formed between the lower part of the sliding surface of the guide rail and the baffle, in which a part of the front pulley case is arranged.

[0021] This enables the effective utilization of the space below the guide rail to arrange the front pulley case, bringing the front pulley case closer to the guide bracket and reducing the possibility of interference between the closing door cable and other members.

[0022] In the above technical solution, the hinge is further provided with a guide roller for guiding the movement of the hinge along the guide rail, and the opening door cable terminal is preferably provided below the guide roller so as to be coaxial with the guide roller.

[0023] This allows the attachment of the opening door cable terminal using the axis of the guide roller, with a simple structure.

Embodiments for Carrying Out the Invention

[0025] Below, an embodiment of the vehicle sliding door drive mechanism 10 according to the present invention will be described with reference to the drawings. In each figure, X represents the vehicle's longitudinal direction, Y represents the vehicle's width direction, and Z represents the vehicle's vertical direction (up and down direction).

[0026] As shown in Figure 1, the vehicle 1 of this embodiment is equipped with a sliding door 4 that opens and closes a door opening 3 provided on the side 2s of the vehicle body 2. Specifically, the vehicle 1 is provided with a plurality of guide rails (upper guide rail 11, center guide rail 12, lower guide rail 13) extending in the vehicle longitudinal direction X, and a plurality of hinges (upper hinge 21, center hinge 22, lower hinge 23) connected to each of these guide rails. That is, the sliding door 4 of this embodiment is supported on the side 2s of the vehicle body 2 via these guide rails and hinges. Furthermore, by moving each hinge along the direction of extension of each guide rail, the sliding door 4 of this embodiment is configured to move along the vehicle longitudinal direction X while remaining along the side 2s of the vehicle body 2.

[0027] In other words, the sliding door 4 of this embodiment moves toward the front of the vehicle (left side in Figure 1) to close the door opening 3, resulting in a fully closed state, and moves toward the rear of the vehicle (right side in the drawing) to open the door opening 3, resulting in a fully open state that allows occupants of the vehicle 1 to get in and out. Furthermore, the vehicle 1 of this embodiment is provided with a sliding door drive mechanism 10 that opens and closes the sliding door 4 based on the driving force of an actuator driven by a motor 7.

[0028] The sliding door drive mechanism 10 of this embodiment is applied to a center guide rail 12 (an example of a guide rail according to the present invention), and the sliding door drive mechanism 10 will be described in detail below with reference to Figures 2 to 9.

[0029] The sliding door drive mechanism 10 for opening and closing the sliding door 4 comprises a guide rail 12, a hinge 22, a closing cable 8, an opening cable 9, and a motor 7.

[0030] A front pulley case 5 is provided in front of the guide rail 12. More specifically, referring to Figures 5, 6, and 9, the front pulley case 5 is provided on the vehicle side of the curved portion that curves inward in the vehicle width direction Y at the tip of the guide rail 12, and a front pulley 51 is provided in the front pulley case 5. A rear pulley case 6 is provided behind the guide rail 12. Referring to Figure 6, the rear pulley case 6 is located behind the rear end of the guide rail 12 in the vehicle longitudinal direction X, but is positioned close to the rear end of the guide rail 12, and a rear pulley 61 is provided in the rear pulley case 6. In this invention, when it is said that a rear pulley case 6 is provided behind the guide rail 12, it is sufficient that the rear pulley case 6 is located further rearward than the front pulley case 5 of the guide rail 12, and the rear pulley case 6 does not necessarily have to be located behind the guide rail 12 in the longitudinal direction.

[0031] Referring to Figure 7, the guide rail 12 has a baffle 16 that extends below the sliding surface 15, and the baffle 16 is formed by bending the guide rail 12. Specifically, the guide rail 12 is formed by bending a plate material to create a sliding surface 15 on which the load roller 24 provided on the hinge 22 slides, and a baffle 16 that extends downward from the sliding surface 15 in the vehicle's vertical direction Z.

[0032] Furthermore, a rubber strip 18 having a fixing portion 180 and an extension portion 181 is fixed to the baffle 16. A recess 182 is formed in the fixing portion 180, and the rubber strip 18 is fixed to the baffle 16 by inserting the baffle 16 into the recess 182. The extension portion 181 extends from the lower end of the fixing portion 180 until it contacts the vehicle body sheet metal 2a. More specifically, referring to Figure 7, the extension portion 181 extends downward from the lower end of the fixing portion 180 so as to inclinate outward in the vehicle width direction Y, and finally contacts the upper surface of the vehicle body sheet metal 2a. In this way, the rubber strip 18 contacts the vehicle body sheet metal 2a, so that when viewed from the front outside the vehicle, there is no gap between the rubber strip 18 and the vehicle body sheet metal 2a due to the contact, and the vehicle body sheet metal 2a on the inside of the vehicle is not exposed.

[0033] The rubber strip 18 is provided with a pair of position-regulating ribs 18a and 18b that extend along the longitudinal direction of the rubber strip 18, and the door closing cable 8, described later, moves along the rubber strip 18 between the pair of position-regulating ribs 18a and 18b. As the door closing cable 8 moves along the outer surface of the fixed part 180, the rubber strip 18 covers the portion of the fixed part 180 corresponding to the entire stroke of the door closing cable 8 in the longitudinal direction.

[0034] One end of the hinge 22 is connected to the sliding door 4, or more specifically, one end of the hinge 22 is pivotally attached to the sliding door 4. A load roller 24 is provided at the other end of the hinge 22, and a guide roller 25 is provided on the hinge 22 to guide the movement of the hinge 22 along the guide rail 12. The hinge 22 is also provided with an open cable terminal 91 and a closed cable terminal 81. The closed cable 8 is connected to the hinge 22 via the closed cable terminal 81 and is guided to the front pulley 51. Specifically, the closed cable 8 is attached to the closed cable terminal 81, and the closed cable terminal 81 is attached to the hinge 22. The open cable 9 is connected to the hinge 22 via the open cable terminal 91 and is guided to the rear pulley 61. Specifically, the open cable 9 is attached to the open cable terminal 91, and the open cable terminal 91 is attached to the hinge 22. The door opening cable terminal 91 is located below the guide roller 25 so as to be coaxial with the guide roller 25. More specifically, the door opening cable terminal 91 and the guide roller 25 share the same axis 25s.

[0035] More specifically, the hinge 22 is provided with a door closing cable terminal mounting member to which the door closing cable terminal 81 is attached, and the door closing cable terminal 81 is, for example, a shaft provided to protrude from the hinge 22. The door closing cable 8 is attached to the door closing cable terminal 81, and the door closing cable terminal 81 is attached to the door closing cable terminal mounting member and connected to the hinge 22.

[0036] Furthermore, the hinge 22 is provided with a door opening cable terminal mounting member to which the door opening cable terminal 91 is attached. The door opening cable terminal 91 is, for example, a shaft that protrudes from the hinge 22 (as described above, in this embodiment, the shaft used as the door opening cable mounting member is coaxial with the shaft 25s of the guide roller 25). The door opening cable 9 is attached to the door opening cable terminal 91, and the door opening cable terminal 91 is attached to the door opening cable terminal mounting member and connected to the hinge 22.

[0037] The door closing cable terminal 81 is positioned in the vehicle's vertical direction Z so that when moved by the door closing cable 8, the door closing cable 8 moves along the baffle 16, and the door opening cable terminal 91 is positioned in the vehicle's vertical direction Z so that when moved by the door opening cable 9, the door opening cable 9 slides in the space above the sliding surface 15 on the guide rail 12.

[0038] Specifically, referring to Figure 7, one end of the hinge 22 extends to the outside of the guide rail cover 17 (the guide rail cover may be a windowpane) and is connected to the sliding door 4 via a connecting mechanism (not shown). A load roller 24 is provided at the other end of the hinge 22, and a guide roller 25 is provided above the load roller 24. The guide roller 25 slides along the guide groove of the guide rail 12, so that the sliding of the load roller 24 along the sliding surface 15 does not deviate from the guide rail 12.

[0039] The door opening cable 9 moves the hinge 22 by moving the door opening cable end 91, which is located below the guide roller 25 so as to be coaxial with the guide roller 25, and also slides along the inner surface of the guide rail 12 in the vehicle width direction Y.

[0040] The door closing cable 8 moves the hinge 22 by moving the door closing cable terminal 81, which is located below the load roller 24 in the vehicle vertical direction Z and outward in the vehicle width direction Y, and also moves along the rubber strip 18.

[0041] Referring to Figures 4 and 8, a guide bracket 88 is provided in front of the rubber strip 18 and fixed below the guide rail 12. The guide bracket 88 has an opening 88a through which the door closing cable 8 enters and exits. After passing through the opening 88a, the door closing cable 8 moves along the rubber strip 18. As a result, the door closing cable 8 is smoothly guided through the guide bracket 88 to the moving surface between the position regulating ribs 18a and 18b in the rubber strip 18.

[0042] Furthermore, the guide bracket 88 is provided with a locking portion 88b, and the guide rail 12 is provided with a locked portion 12b, and the guide bracket 88 is fixed to the guide rail 12 by locking the locking portion 88b and the locked portion 12b together. The locking portion 88b is, for example, a locking claw, and the locked portion 12b is, for example, an opening.

[0043] The part of the guide bracket 88 that comes into contact with the door closing cable 8 is provided with a recessed portion 88c where grease is stored. Referring to Figure 4, the recessed portion 88c has a structure that is recessed from the outside to the inside in the vehicle width direction Y, and by storing grease in the recessed portion 88c, the door closing cable 8 can be effectively lubricated.

[0044] Referring to Figure 9, a dwelling space S is formed between the lower part of the sliding surface 15 of the guide rail 12 and the baffle 16, and a part of the front pulley case 5 is provided therein. In this embodiment, the dwelling space S is close to the opening 88a of the guide bracket 88, and the closing cable 8 pulled from the front pulley 51 can be directly guided into the guide bracket 88 without interfering with other members, and the closing cable 8 can be further lubricated before being guided to the rubber strip 18.

[0045] The door closing cable 8 is pulled through the door closing cable sleeve 80 and guided to the front pulley 51, and after being guided by the front pulley 51, it continues to pass through the guide bracket 88 and is attached to the hinge 22 by being connected to the door closing cable terminal 81.

[0046] The door opening cable 9 is pulled through the door opening cable sleeve 90 and guided to the rear pulley 61, and then connected to the door opening cable terminal 91 to be attached to the hinge 22.

[0047] Motor 7 is connected to the door opening cable 9 and the door closing cable 8. When the actuator is driven by motor 7, the door closing cable 8 or the door opening cable 9 is driven, causing the load roller 24 of the hinge 22 connected to the door closing cable 8 or door opening cable 9 to slide back and forth along the sliding surface 15 of the guide rail 12, thereby driving the sliding door 4 to open and close. Figure 6 shows the front-to-back range in which the hinge 22 can move along the guide rail 12.

[0048] In a front view of the side of the vehicle, when the sliding door 4 is closed, the opening cable 9 is located inside the guide rail 12 and is blocked by the guide rail cover 17. When the sliding door 4 is open, the closing cable 8 is exposed outside the rubber strip 18, but is blocked by the sliding door 4 itself, resulting in a good appearance for the vehicle.

[0049] Furthermore, since the door closing cable terminal 81 is located outside the vehicle width direction Y relative to the rubber strip 18, the door closing cable terminal 81 does not come into direct contact with the rubber strip 18 during movement, and the door closing cable terminal 81 can be easily designed to prevent deformation or excessive wear of the rubber strip 18.

[0050] Although preferred embodiments of the present invention have been described above, these embodiments are subject to various modifications.

[0051] For example, the above embodiment shows the sliding door drive mechanism applied to a vehicle, but the present invention is not limited thereto, and the sliding door drive mechanism can be applied to any sliding door.

[0052] For example, in the above embodiment, a sliding door 4 that opens to the rear is shown, but the present invention is not limited thereto, and the sliding door 4 may be a sliding door that opens to the front.

[0053] For example, in the above embodiment, a configuration was shown in which a recess 182 is formed in the fixing portion 180 of the rubber strip 18, which fixes the rubber strip 18 to the baffle 16 by inserting the baffle 16. However, the present invention is not limited to this, and the fixing portion 180 and the extension portion 181 of the rubber strip 18 may be a single sheet-like rubber strip, and the fixing portion 180 may be bonded and fixed to the outer surface of the vehicle of the baffle 16 with an adhesive.

[0054] For example, in the above embodiment, a configuration is shown in which a locking portion 88b is provided on the guide bracket 88 and a locked portion 12b is provided on the guide rail 12. However, the present invention is not limited to this, and a configuration in which a locked portion is provided on the guide bracket and a locking portion is provided on the guide rail is also possible.

[0055] For example, in the above embodiment, the hinge and the cable end bracket are shown to be integrally configured, but the present invention is not limited thereto, and the hinge may be configured separately from the cable end bracket.

[0056] The present invention has been described above with reference to specific examples. However, the present invention is not limited to these specific examples. Designs obtained by persons skilled in the art by appropriately modifying these specific examples are included within the scope of the present invention, as long as they possess the features of the present invention.
