[0002] This application claims the benefit of Korean Patent Application No. 10-2020-0129546, filed on October 7, 2020, with the Korean Intellectual Property Office, which is incorporated herein by reference. Technical Field
[0003] The implementation plan relates to a device for preventing the sliding doors of a vehicle from shaking. Background Technology
[0004] Typically, a vehicle has a passenger compartment of a predetermined size in which the driver or accompanying passenger can sit. A passenger compartment door is mounted 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 along the longitudinal direction of the vehicle, and the rear sliding door is installed at the rear along the longitudinal direction of the vehicle. The front and rear sliding doors are typically installed to move along tracks installed on the vehicle body or doors.
[0006] Figure 1 To illustrate the vehicle body, the vehicle has doors that open or close in a sliding manner as described in the related art. The doors in the related art (which operate in a sliding manner to open or close the passenger compartment) include an upper rail 10, a central rail 20, and a lower rail 30. The upper rail 10 is configured to support the upper part of the door 1 when it slides, ensuring forward / backward sliding operation of the door 1 engaged with the vehicle body 2. The central rail 20 is configured to support the middle part of the door 1 when it slides, and the lower rail 30 is configured to support the lower part of the door 1 when it slides.
[0007] However, since the tracks 10, 20 and 30 used to slide the door 1 and the components associated with the tracks 10, 20 and 30 are mounted on the vehicle body, there are concerns that the weight of the vehicle and the number of vehicle components will increase, and the design freedom of the vehicle will be reduced.
[0008] Therefore, a two-track door device for vehicles (in which only the central and lower tracks support the door, allowing it to slide) has been developed to solve the aforementioned problems in related technologies. As an example of this technology, Korean Patent No. 10-1584536 discloses a sliding door device for vehicles.
[0009] The prior art shows a configuration in which a door track (central track) is mounted on the sliding door and a body track is mounted on the body, such that a central slider engaged with the door track and a lower slider engaged with the body track can move to open or close the sliding door.
[0010] Reference Figure 1 In the related art, a sliding structure has two support points supporting a sliding door, including a contact point A between a vehicle body rail and a lower slider and a contact point B between a central rail and a central slider. However, as shown in Figure 2 There is a problem in that the vehicle door 1 rocks in a direction indicated by an arrow shown in Figure 2 There is a concern that the rocking of the vehicle door 1 generates a gap between the vehicle door and a door frame when the vehicle door is opened or closed, and the rocking of the vehicle door 1 deteriorates the marketability of the vehicle. SUMMARY
[0011] Embodiments of the present application relate to an apparatus for preventing a sliding door of a vehicle from rocking.
[0012] In an exemplary embodiment, the apparatus includes a central rail installed to a middle portion of a door panel of a vehicle door coupled to a vehicle body. A vehicle door rail is installed to a lower side of the door panel. A vehicle body rail is coupled to the vehicle body to be opposite to the vehicle door rail. A vehicle body rail slider is coupled to one face of the vehicle body rail to be slidable in a front-rear direction along the vehicle body rail. A vehicle door rail slider is coupled to the vehicle door rail to be slidable in the front-rear direction along the vehicle door rail. A transmission wheel is rotatable in response to a movement of the vehicle body rail slider. A speed reducer is directly connected to the transmission wheel and is configured to reduce a rotational speed of the transmission wheel. A second arm is hingedly coupled to the speed reducer and is configured to move the vehicle door rail slider.
[0013] Embodiments can provide an apparatus for preventing a sliding door of a vehicle from rocking, in which the apparatus has a vehicle door opened or closed in a sliding manner and a transmission wheel structure for preventing the sliding door from rocking during an operation of opening or closing the vehicle door.
[0014] As compared to a two-rail type sliding door having only a central rail and a lower rail in the related art, the apparatus according to embodiments of the present application configured as described above can support the vehicle door at three support points. Accordingly, it is possible to stably open or close the sliding door without rocking, and it is possible to prevent a gap between the vehicle door and a door frame from being generated due to the rocking of the vehicle door.
[0015] Since the apparatus for preventing a sliding door of a vehicle from rocking has a relatively simple structure, the apparatus for preventing a sliding door of a vehicle from rocking according to embodiments of the present application can be easily applied without additionally changing a structure of a sliding door in the related art.
[0016] Since the transmission wheel and the speed reducer are used, the rotation amount of the second arm, which rotates according to the moving distance of the body rail slider when the door is opened, can be adjusted. Thus, the operation trajectory of the door can be changed to a desired trajectory when the door is opened or closed, thereby obtaining an effect of improving the design freedom.

[0027] Referring to the accompanying drawings, the device for preventing the sliding door of a vehicle from rocking according to the present invention (hereinafter referred to as the "anti-rocking device") includes: a central track 120, a door track 130, and a body track 140, wherein the central track 120 is installed at the center of the door panel 110 of the door 100 which is engaged with the body 2 of the vehicle, the door track 130 is installed on the lower side of the door panel 110, and the body track 140 is engaged with the body 2 to be opposite to the door track 130.
[0028] The central track 120, door track 130, and body track 140 are all strip-shaped or rod-shaped and extend parallel to the door panel 110. In this exemplary embodiment, the central track 120 and door track 130 are both track shapes including a pair of rods, and the body track 140 has a frame 141 formed in the form of a quadrilateral tubular member.
[0029] The anti-sway device according to the present invention includes: a vehicle body track slider 170 and a door track slider 180, wherein the vehicle body track slider 170 is engaged to one side of a vehicle body track 140 in the direction of the door panel 110 so as to be slidable along the vehicle body track 140 in the front-rear direction; and the door track slider 180 is engaged to a door track 130 so as to be slidable along the door track 130 in the front-rear direction.
[0030] In order to slide the vehicle body track slider 170 in response to the operation of the door 100, the first arm 190 is connected to the vehicle body track slider 170.
[0031] Specifically, a bracket hinge 192 located on one side of the first arm 190 is hinged to a bracket 191 attached to the door panel 110, and a slider hinge 193 located on the other side of the first arm 190 is hinged to the body 171 of the vehicle track slider 170.
[0032] In order to slide the door track slider 180 in response to the operation of the door 100, the second arm 200 is connected to the door track slider 180.
[0033] Specifically, the door track slider 180 has a vertical surface 181 that engages with the door track 130, and a horizontal surface 182 that is bent to be perpendicular to the vertical surface 181. One hinge 201 of the second arm 200 is hingedly engaged with the door track slider 180, while the other hinge 202 of the second arm 200 is hingedly engaged with the shaft (not shown) of the reducer 160, which is mounted on a mounting plate 211 of a fixing unit 210 attached to the vehicle body 2. A drive wheel 150 with a cable 151 wound around it is mounted on the upper side of the reducer 160.
[0034] The speed reducer 160 is directly connected to the transmission wheel 150 attached to the upper side of the speed reducer 160, and functions to reduce the rotational speed (rpm) of the transmission wheel 150. Accordingly, the amount of rotation of the second arm 200, which is hingedly coupled to the shaft of the speed reducer 160, is adjusted according to the reduction ratio of the speed reducer 160.
[0035] The cable 151 wound around the transmission wheel 150 extends along the conveying roller 142 provided on the frame 141 of the body rail 140, and is returned to the transmission wheel 150 via the connecting roller 172 provided on the main body 171 of the body rail slider 170.
[0036] Accordingly, when the body rail slider 170 moves in the front and rear direction in response to the operation of the door 100, the cable 151 extended via the connecting roller 172 of the body rail slider 170 is moved by being forced in the clockwise or counterclockwise direction, and the transmission wheel 150 is rotated by the movement of the cable 151. In a state in which the rotational speed of the transmission wheel 150 is reduced by the speed reducer 160, the rotational force of the transmission wheel 150 is transmitted to the other hinge 202 of the second arm 200, thereby rotating the second arm 200.
[0037] On the other hand, the central rail slider 122 is installed to be movable in the front and rear direction along the central rail 120 of the door panel 110, and is connected to the central rail rotation member 121 attached to the body 2.
[0038] Accordingly, by the operation of opening or closing the door 100, the central rail slider 122 connected to the central rail rotation member 121 moves in the front and rear direction along the central rail 120.
[0039] In the anti-shaking device according to the present application configured as described above, by the operation of opening or closing the door 100, the body rail slider 170 and the door rail slider 180 are respectively slid in the front and rear direction on the body rail 140 and the door rail 130. Further, in response to the above operation, the first arm 190 and the second arm 200 are opened and unfolded in a direction toward the outside of the body 2, or are folded in a direction toward the inside of the body 2. The detailed operation will be described below.
[0040] Next, the operation of the device for preventing the shaking of the sliding door of the vehicle according to the present application configured as described above will be described.
[0041] Figures 6A to 6E To show a schematic view of the state of the sliding door operation of the vehicle according to the present application.
[0042] The drawings show the operating state in which the door 100 mounted to the vehicle body 2 is opened. For the convenience of description, the side on which the first arm 190 is mounted is defined as the front side, and the side on which the second arm 200 is mounted is defined as the rear side.
[0043] First, in the state in which the door 100 is closed as shown in FIG. 1, the door 100 is positioned parallel to the vehicle body rail 140, the vehicle body rail slider 170 is positioned at the front end of the vehicle body rail 140, and the door rail slider 180 is positioned at the rear end of the door rail 130. Figure 6A
[0044] In this state, when the door 100 moves rearward upon opening, the first arm 190 coupled to the door panel 110 moves rearward along with the movement of the door 100, thereby starting to move the vehicle body rail slider 170 rearward, as shown in FIG. 2. Figure 6B
[0045] In this state, when the door 100 continues to move rearward, as shown in FIG. 3, the cable 151 extending via the connecting roller 172 of the rearwardly moving vehicle body rail slider 170 is moved by the clockwise force, the transmission wheel 150 rotates according to the movement of the cable 151, and, in the state in which the rotation speed of the transmission wheel 150 is reduced by the speed reducer 160, the rotation force of the transmission wheel 150 is transmitted to the other hinge 202 of the second arm 200, so that the second arm 200 is unfolded toward the outside of the vehicle 2, and the door rail slider 180 moves forward along the door rail 130. Figure 6C By the operation of opening the door 100, the central rail slider 122 connected to the central rail turning member 121 attached to the vehicle body 2 moves forward along the central rail 120.
[0046] Next, as the door 100 continues to move rearward, as shown in FIG. 4, the vehicle body rail slider 170 moves rearward, and the door rail slider 180 moves forward. As shown in FIG. 5, when the door 100 of the vehicle is completely opened, in the state in which the first arm 190 and the second arm 200 are completely unfolded toward the outside of the vehicle 2, the vehicle body rail slider 170 and the door rail slider 180 are positioned at the points closest to each other.
[0047] Figure 6D On the other hand, the operation of closing the door 100 according to the present application is performed in the reverse order of the operation of opening the door 100. Figure 6E
[0048]
[0049] Accordingly, when the vehicle door 100 is opened or closed, the anti-rattling device according to the present application, which is operated as described above, can support the movement of the vehicle door 100 at three points by the vehicle body rail slider 170, the vehicle door rail slider 180, and the central rail slider 122. Thus, compared to the configuration in the related art in which the movement of the vehicle door is supported at two points by only the central slider and the lower slider, it is possible to prevent rattling of the vehicle door 100, to stably open or close the vehicle door 100, and to prevent a gap between the vehicle door and the vehicle door frame from being generated due to rattling of the vehicle door.
