[0002] This application claims the benefit of Korean Patent Application No. 10-2020-0134126, filed on October 16, 2020, with the Korean Intellectual Property Office, which is incorporated herein by reference. Technical Field

[0003] This invention relates to a structure for preventing sliding doors from shaking. Background Technology

[0004] Typically, a vehicle has a passenger compartment of a predetermined size in which the driver or accompanying passengers can sit. The passenger compartment door is installed on the vehicle body to open or close the passenger compartment.

[0005] The sliding passenger compartment opening / closing door includes a front sliding door and a rear sliding door. The front sliding door is installed at the front of the vehicle in the longitudinal direction, and the rear sliding door is installed at the rear of the vehicle in the longitudinal direction. The front and rear sliding doors are typically installed to move along tracks installed on the vehicle body or doors.

[0006] However, the sliding passenger compartment opening / closing door in the related technology requires three tracks (upper track, middle track, and lower track), which support the upper, middle, and lower parts of the door respectively during opening or closing. Furthermore, the sliding passenger compartment opening / closing door also requires track-related components. For this reason, the sliding passenger compartment opening / closing door in the related technology has the following problems: increased vehicle weight and number of components, and reduced design freedom.

[0007] Therefore, a dual-track door system for vehicles has been developed, in which the sliding door is slidably supported only by a middle track and a lower track. For example, Korean Patent No. 10-1684536 (Sliding Door System for Vehicles) discloses that a door track (i.e., the middle track) is installed on the sliding door, and a body track (i.e., the lower track) is installed on the vehicle body. The sliding door opens or closes as the central slider, which is engaged with the door track, and the lower slider, which is engaged with the body track, move.

[0008] However, reference Figure 1In the sliding structure of the related technology, two support points are formed vertically to support the sliding door. These two support points include contact point A between the vehicle track 10 and the lower slider, and contact point B between the middle track 20 and the central slider. However, this presents a problem where the sliding door rotates about the imaginary axis X connecting the contact points. Furthermore, because the support points for the sliding door are only formed on the imaginary axis X, when a load is applied to the sliding door, only one contact point A remains in the load direction (the direction of the imaginary axis X). Therefore, the problem is that the sliding door cannot be stably supported, and it will wobble when moving. Summary of the Invention

[0009] This invention relates to a structure for preventing a sliding door from shaking. A specific embodiment relates to such a structure for preventing a sliding door from shaking in a vehicle equipped with a sliding door and having only a lower track.

[0010] The embodiments of the present invention provide a novel structure that prevents the sliding door from shaking and supports the load when the sliding door is opened or closed in a vehicle equipped with a sliding door and having only a lower track.

[0011] An exemplary embodiment of the present invention provides a structure for preventing a sliding door from rocking, the structure comprising: a slider rotatably connected to a track; a movable support unit fixed to a door on one side of the movable support unit and rotatably connected to the slider on the other side of the movable support unit, and configured to support the door; and a latch-claw locking unit comprising a latch and a claw, the latch and the claw being configured to lock or unlock each other during rotation, wherein when the latch rotates by being latched by a latching member, the latch and the claw cooperate to restrict movement of the slider in a first direction or movement of the movable support unit in a second direction.

[0012] According to the embodiments of the present invention, the following effects are achieved.

[0013] First, the rotational factor required to rotate the door in a vehicle equipped with a sliding door in the relevant technology is eliminated, thus minimizing the shaking of the door during operation.

[0014] Secondly, the upper and central components configured to move the doors in vehicles equipped with sliding doors in related technologies have been removed, thus increasing the design freedom of the vehicle and ensuring the overall interior space.

[0015] Third, when the door is operated, the movable support unit and the track roller unit can support the door while preventing it from shaking.

[0016] Fourth, in order to prevent the door from shaking, when the door moves in either the first or second direction, the movement of the door in the other direction is controlled and restricted. Attached Figure Description

[0027] The following description, with reference to the accompanying drawings, details a structure for preventing a sliding door from rocking according to an exemplary embodiment of the invention. The terms or words used herein should not be construed as limited to their ordinary or dictionary meanings, and are to be interpreted as meanings and concepts consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concepts of the terms, in order to best describe his / her own invention.

[0028] According to an exemplary embodiment of the present invention, the vehicle has only a lower track 100 (a track disposed on the lower side of the vehicle), and has neither a middle track 20 (a track disposed on the lower side of the vehicle). Figure 1 The central track of the vehicle shown is not on the upper track 30 (set in the middle). Figure 1 The track on the upper side of the vehicle shown.

[0029] The sliding door 1 includes a front door and a rear door, and a structure for preventing the sliding door from rocking, according to an exemplary embodiment of the present invention, is applied to the lower track 100 of either the front door or the rear door. Therefore, the structures for preventing the sliding door from rocking applied to the front door and the rear door are identical in configuration and operating principle. However, in this specification, an example of the structure for preventing the sliding door from rocking being applied to either sliding door 1 will be described.

[0030] Figure 2 A schematic diagram illustrating the state of a structure for preventing a sliding door from shaking, according to an exemplary embodiment of the present invention, applied to a vehicle door, and Figure 3 for Figure 2 An enlarged schematic diagram of part E in the diagram.

[0031] refer to Figure 2 and Figure 3 According to an exemplary embodiment of the present invention, a structure for preventing the sliding door from shaking is provided on the underside of the vehicle body 2 and the door 1, and includes a lower track 100, a track roller unit 200, a slider 300, a movable support unit 400, and a latching-claw locking unit 500.

[0032] In this configuration, the track roller unit 200 moves in the longitudinal direction (T direction) of the vehicle body 2, and the T direction is defined as the first direction in this specification. Furthermore, the movable support unit 400 moves in the width direction (L direction) of the vehicle body 2, and the L direction is defined as the second direction in this specification.

[0033] Figure 4 This is a schematic diagram illustrating the lower track according to an exemplary embodiment of the present invention.

[0034] refer to Figure 4The lower rail 100 extends in the longitudinal direction of the vehicle body 2 and is installed on the vehicle body 2. In an exemplary embodiment of the present invention, the lower rail 100 is a straight rail.

[0035] Roller groove 102 is formed on one surface of lower track 100 (the surface facing door 1). First stop pin 106 is disposed on one side of lower track 100. First stop pin 106 may be a snap-fit ​​member, which may be snapped by a first snap-fit ​​member 510 described below, and may have various shapes. In an exemplary embodiment of the invention, first stop pin 106 has an approximately cylindrical shape.

[0036] The track roller unit 200 is rotatably connected to the lower track 100. A first roller 202 is disposed on one surface of the track roller unit 200 and inserted into the roller groove 102 of the lower track 100. When the first roller 202 is inserted into the roller groove 102, the track roller unit 200 can roll along the lower track 100 in a first direction. In this case, the first roller 202 functions as a bearing.

[0037] Figure 5 This is a schematic diagram illustrating the engagement state of the slider and the track roller unit according to an exemplary embodiment of the present invention. Figure 6 To show along Figure 5 A schematic diagram of the cross section obtained by line SS′ in the diagram.

[0038] The slider 300 is fixedly mounted to the track roller unit 200 on one side in its longitudinal direction. The slider 300 has a predetermined length and a predetermined width. In this case, the predetermined length refers to the length of the slider when it does not interfere with the door 1 when the door 1 is fully closed. The predetermined width refers to the width of the slider when it can support the door 1. The length and width of the slider 300 can be set without restriction.

[0039] The slider 300 has an internal space extending along its longitudinal direction, into which the movable support unit 400, described below, can be inserted. The internal space can be referred to as a movement path, along which the movable support unit 400 can roll. There are no restrictions on the location of the internal space formed in the slider 300. Furthermore, the areas of the slider 300 other than the internal space can have structures and materials that maintain the rigidity of the slider 300.

[0040] refer to Figure 6 The internal space has roller movement paths 304a and 304b and a support member movement path 302. The second roller 402, which will be described below, can move in the roller movement paths 304a and 304b, and the support member 401 can move in the support member movement path 302. Figure 6The roller movement paths 304a and 304b are shown to be formed on both sides of the support member movement path 302, but the shape of the internal space can vary depending on the shape of the moving support unit 400.

[0041] A movable hole 306 is formed on one surface of the slider 300 and extends in the longitudinal direction of the slider 300. The second abutment 406, which will be described below, can move along the movable hole 306.

[0042] Figure 7 This is a schematic diagram illustrating a movable support unit according to an exemplary embodiment of the present invention.

[0043] The movable support unit 400 includes a support member 401 and a second roller 402. One end of the support member 401 can be fixedly mounted to the vehicle door 1 via a mounting bracket 408. The support member 401 may have a structure and material with sufficient rigidity to support the vehicle door 1. The second roller 402 is disposed at the other end of the support member 401. According to an exemplary embodiment of the present invention, the second roller 402 is disposed on both sides of the support member 401; however, there is no limitation on the position and number of the second rollers 402 disposed on the support member 401.

[0044] As described above, the movable support unit 400 can be inserted into the internal space of the slider 300, the internal space having a shape corresponding to the shape of the movable support unit 400, and the movable support unit 400 can roll. In this case, the second roller 402 serves as a bearing. When the movable support unit 400 mounted on the door 1 is connected to the slider 300 mounted on the track roller unit 200, the door 1 and the body 2 face each other. In this case, the movable support unit 400 can move relative to the slider 300 in a second direction.

[0045] The second striking pin 406 is disposed on one side of the movable support unit 400. The second striking pin 406 may be a snap-fit ​​member, which may be snapped by a second snap-fit ​​member 530, which will be described below, and may have various shapes. In an exemplary embodiment of the invention, the second striking pin 406 has an approximately cylindrical shape.

[0046] Figure 8 To show when viewed from above Figure 5 The diagram shows a snap-fit ​​locking unit.

[0047] The latch-claw locking unit 500 can lock or unlock the latch and claw together by rotating the latch and claw, thereby controlling the movement of the slider 300 in the first direction and the movement of the moving support unit 400 in the second direction. The latch-claw locking unit 500 includes a first latch 510, a first claw 520, a second latch 530, and a second claw 540.

[0048] The first engaging member 510 includes a first insertion groove 512 and a guide member. The first insertion groove 512 is recessed inward so that the first striking pin 106 can be inserted into the first insertion groove 512. The guide member is disposed on both sides of the first insertion groove 512 and configured to guide the first striking pin 106 so that the first striking pin 106 is inserted into the first insertion groove 512. The first engaging member 510 is rotatably connected to the track roller unit 200. However, as long as the first striking pin 106 can be inserted into the first insertion groove 512, the first engaging member 510 can be rotatably engaged to the slider 300.

[0049] The first card connector 510 includes a first card slot 513 and a first card connector unlocking part 515. The first card slot 513 is formed to be engaged by a first card claw 520, so that the first card connector 510 and the first card claw 520 are locked to each other. The first card connector unlocking part 515 is configured to have a path such that when the first card connector 510 is unlocked from the first card claw 520, the first card claw 520 can contact and move along the path to the first card connector unlocking part 515.

[0050] The first latching spring (which assists in the rotation of the first latching member 510) can be disposed on the rotation shaft 517 of the first latching member 510. With the first insertion slot 512 spaced apart from the first abutment 106, the first latching spring can move in the direction toward the first abutment 106 (based on...). Figure 8 A spring force is applied to the first latching member 510 in the clockwise direction of the rotation axis of the first latching member. Therefore, the first latching member 510 can maintain its posture so as to be latched by the first abutment 106.

[0051] One end of the first rod 550 can be rotatably connected to the first latching member 510. The rotation axis 519 of the first rod 550 is spaced apart from the rotation axis 517 of the first latching member 510, such that the first latching member 510 moves in one direction (based on the movement of the first rod 550). Figure 8 The first snap-fit ​​component rotates clockwise on its rotating shaft.

[0052] The first latch 520 includes a first latching portion 523, a first latch unlocking portion 525, and a first connecting portion 526. The first latching portion 523 has a shape corresponding to the first latching groove 513 and is configured to insert into the first latching groove 513, so that the first latch 520 can be locked to the first latching member 510. The first latch unlocking portion 525 has a shape corresponding to the first latch unlocking portion 515 and is configured to provide a path along which the first latch 520 can contact and move with the first latch 510. The first connecting portion 526 can be connected to a second rod 560. One end of the second rod 560 is rotatably connected to the first connecting portion 526.

[0053] In an exemplary embodiment of the present invention, the first latching portion 523 has an approximate hook shape, but there is no limitation on the shape of the first latching portion 523, as long as the first latching portion 523 corresponds to the first latching groove 513. The first claw 520 is positioned on one side of the first latching member 510 and is rotatably connected to the slider 300.

[0054] The first pawl spring (which assists in the rotation of the first pawl 520) can be mounted on the rotation shaft 527 of the first pawl 520. The first pawl spring can be positioned in the opposite direction to the direction in which the first latching spring applies its elastic force (based on...). Figure 8 A spring force is applied to the first pawl 520 in the counterclockwise direction of the rotation axis of the first pawl. Therefore, the first pawl 520 can assist the first latching member 510 in maintaining its posture so that it can be latched by the first abutment 106.

[0055] refer to Figure 8 The second latch 530 and the second latch 540 have shapes similar to the first latch 510 and the first latch 520, respectively.

[0056] The second latching member 530 includes a second insertion groove 532 and a guide member. The second insertion groove 532 is recessed inward so that the second striking pin 406 can be inserted into the second insertion groove 512. The guide member is disposed on both sides of the second insertion groove 532 and configured to guide the second striking pin 406 so that the second striking pin 406 is inserted into the second insertion groove 532. The second latching member 530 is rotatably connected to the slider 300. In this case, the second insertion groove 532 is positioned near the moving hole 306.

[0057] The second latching member 530 includes a second latching groove 533 and a second latching member unlocking part 535. The second latching groove 533 is formed to be engaged by a second latching claw 540, thereby locking the second latching member 530 and the second latching claw 540 together. The second latching member unlocking part 535 is configured such that the second latching claw 540 can contact and move along this path. In an exemplary embodiment of the present invention, the second latching part 543 has an approximate hook shape, but the shape of the second latching part 543 is not limited, as long as the second latching part 543 corresponds to the second latching groove 533.

[0058] The second locking spring (which assists in the rotation of the second locking member 530) can be disposed on the rotation shaft 537 of the second locking member 530. With the second insertion slot 532 spaced apart from the second abutment 406, the second locking spring can move in the direction towards the second abutment 406 (based on...). Figure 8 A spring force is applied to the second latch 530 in the counterclockwise direction of the rotation axis of the second latch. Therefore, the second latch 530 can maintain its posture so as to be latched by the second abutment 406.

[0059] The other end of the second rod 560 is rotatably connected to the second latching member 530. The rotation axis 539 of the second rod 560 is spaced apart from the rotation axis 537 of the second latching member 530, such that the second latching member 530 moves in another direction (based on...) Figure 8 The second snap-fit ​​component rotates counterclockwise on its rotating shaft.

[0060] The second latch 540 includes a second latching portion 543, a second latch unlocking portion 545, and a second connecting portion 546. The second latching portion 543 has a shape corresponding to the second latching groove 533 and is configured to insert into the second latching groove 533, so that the second latch 540 can be locked to the second latching member 530. The second latch unlocking portion 545 has a shape corresponding to the second latch unlocking portion 535 and is configured to provide a path along which the second latch 540 can contact and move with the second latch 530. The second connecting portion 546 can be connected to the first rod 550. The other end of the first rod 550 is rotatably connected to the second connecting portion 546.

[0061] The second pawl spring (which assists in the rotation of the second pawl 540) can be mounted on the rotation shaft 547 of the second pawl 540. The second pawl spring can be positioned in the opposite direction to the direction in which the second latching spring applies its elastic force (based on...). Figure 8 A spring force is applied to the second pawl 540 in the clockwise direction of the rotation axis of the second pawl. Therefore, the second pawl 540 can assist the second latching member 530 in maintaining its posture so that it can be latched by the second abutment 406.

[0062] Figure 9A and Figure 9B This is a schematic diagram illustrating the process of operating the structure for preventing a sliding door from rocking according to an exemplary embodiment of the present invention when the door moves from a closed state to an open state. Figure 10A and Figure 10B This is a schematic diagram illustrating the process of operating a structure for preventing a sliding door from rocking according to an exemplary embodiment of the present invention when the door moves from an open state to a closed state.

[0063] First, refer to Figure 9A and Figure 9B The process of operating the anti-shaking structure according to an exemplary embodiment of the present invention is described when the door 1 is moved from the closed state to the open state.

[0064] Figure 9A The door 1 is shown in the closed position. The track roller unit 200 is positioned on the lower track 100 in the fully closed position of the door 1, and the movable support unit 400 is fully inserted into the slider 300. In this case, the second striker 406 is positioned at one end of the movable hole 306.

[0065] The first latching member 510 rotates slightly in the second direction, causing the first striking pin 106 to insert into the first insertion slot 512. Since the first latching portion 523 is engaged by the first latching slot 513, the first latching member 510 and the first latching claw 520 are locked together and cannot rotate. Therefore, because the first latching member 510 and the first latching claw 520 are locked, the track roller unit 200 cannot move in the first direction (specifically, in the direction in which the door 1 opens in the first direction). In this situation, the door 1 and the slider 300 connected to the track roller unit 200 naturally cannot move in the first direction.

[0066] The second latch 530 rotates slightly in the second direction, causing the second insertion slot 532 to face the second abutment 406. Since the second latch unlocking part 535 and the second latch unlocking part 545 are in contact with each other, the second latch 530 and the second latch 540 are not locked together. Therefore, the movable support unit 400 can move in the second direction (specifically, in the direction in which the door 1 and the body 2 are away from each other).

[0067] In this state, the operation of the second latch 530 and the second latch 540 will be described. As the movable support unit 400 moves, the second striker 406 moves to the other side of the movable hole 306 and then inserts into the second insertion slot 532. When the movable support unit 400 moves further, the second latch 530 moves in one direction (based on...) Figure 9AThe second latching member rotates in the clockwise direction (based on the rotation axis of the second latching member), while the second latch 540 rotates in the other direction (based on the rotation axis of the second latching member). Figure 9A The second claw rotates counterclockwise on the rotation axis of the second claw. In this case, when the second latching part 543 moves along the second latching member unlocking part 535 and is then latched by the second latching groove 533, the second latching member 530 and the second claw 540 are locked together and cannot rotate.

[0068] The process of operating the first lever 550 and the second lever 560 will be described. When the second jaw 540 rotates, the first lever 550 moves in the direction toward the position of the first latch 510, so that the first latch 510 is positioned in another direction (based on...). Figure 9A The first latching member rotates in the counterclockwise direction (on the rotation axis of the first latching member). Furthermore, when the second latching member 530 rotates, the second rod 560 moves in a direction toward the position of the second latching member 530, so that the second pawl 540 rotates in one direction (based on...). Figure 9A The first latch rotates clockwise on the rotation axis of the first latch 510. With the first latch 510 and the first latch 520 locked together, the first latch 523 is pulled out of the first latch slot 513 and moves along the first latch unlocking part 515 by the operation of the first lever 550 and the second lever 560, thereby unlocking the first latch 510 and the first latch 520. Therefore, the track roller unit 200 can move in the first direction (specifically, in the direction in which the door 1 opens).

[0069] Figure 9B The state is such that the movable support unit 400 cannot move in the direction in which the door 1 and the body 2 are far apart from each other along the second direction, while the track roller unit 200 can move in the direction in which the door 1 is opened along the first direction.

[0070] Subsequently, when door 1 is operated in the direction of door 1 opening, the first latch 510 operates in the other direction ( Figure 9B It rotates clockwise. As described above, the first latching member 510 rotates smoothly by the elastic force of the first latching member spring.

[0071] On the other hand, when door 1 moves from the open state to the closed state, the process of operating the structure for preventing the sliding door from shaking according to the exemplary embodiment of the present invention can be performed in the reverse order of the above process, and those skilled in the art can refer to... Figure 10A and Figure 10B Fully understand the process.

[0072] Meanwhile, according to an exemplary embodiment of the present invention, the slider 300 and the movable support unit 400 can prevent the door 1 from shaking while it is opening or closing, and since the door 1 moves linearly only in either the first or second direction, it can further prevent the door 1 from shaking.

[0073] The invention has been described with reference to limited exemplary embodiments and accompanying drawings, but is not limited thereto. The described exemplary embodiments can be modified or altered in various ways by those skilled in the art within the spirit of the invention and within the scope of its equivalents, including the appended claims.
