Description

Technical Field

[0001] The invention relates to a vehicle sliding door switch device. Background Art

[0002] Doors are installed on the sides of vehicles to enable passengers to enter and exit the vehicle compartment or to load or unload cargo onto or from the vehicle.

[0003] For example, a sliding door is installed at a side of a vehicle, and the sliding door is configured to slide in a longitudinal direction of the vehicle and open / close the side of the vehicle.

[0004] The sliding door in the closed state pops up a predetermined distance in the lateral direction of the vehicle, and then slides in the longitudinal direction of the vehicle to open. To close the sliding door, the sliding door is operated in the reverse order.

[0005] In the related art, a central rail for guiding the sliding operation of the sliding door is installed on the side of the vehicle, and a roller moving along the central rail is installed on the sliding door. The sliding door should be ejected as far as possible in the lateral direction of the vehicle to ensure the operable space of the central rail and the roller and prevent the inner surface of the sliding door from interfering with the outer surface of the vehicle.

[0006] However, if the distance that the sliding door pops out from the outer surface of the vehicle increases, there is a problem that passengers waiting to enter the vehicle or people staying near the vehicle may be injured by a collision caused by the sliding door popping out.

[0007] Furthermore, when the sliding door is closed, the center rail installed at the side of the vehicle is exposed to the outside of the vehicle, which affects the appearance of the vehicle. Summary of the invention

[0008] The present invention relates to a vehicle sliding door switch device. The present invention relates to a vehicle sliding door switch device capable of opening and closing a sliding door located at a side of a vehicle and opened and closed in a longitudinal direction of the vehicle.

[0009] Embodiments of the present invention provide a vehicle sliding door opening and closing device that can stably open and close a sliding door without using a center rail and can minimize the distance that the sliding door protrudes from a side of the vehicle during the operation of opening and closing the sliding door.

[0010] According to one embodiment of the present invention, a vehicle sliding door switch device is provided, which includes: a bracket slidably installed along the longitudinal direction of the vehicle; a pair of connecting rods rotatably installed on the bracket in a manner spaced apart from each other, one end of the pair of connecting rods being hinged to the sliding door of the vehicle; and a pop-up unit, which is used to pop the sliding door out of the vehicle body by rotating the pair of connecting rods at the initial stage of the opening operation of the sliding door.

[0011] In the vehicle sliding door opening and closing device, the pop-up unit may include rollers installed at the other ends of the pair of links and a moving guide member that rotates the pair of links at an initial stage of an opening operation of the sliding door by guiding a trajectory of the rollers.

[0012] In a vehicle sliding door switch device, the movable guide may include: a first pop-up section formed in the lateral direction of the vehicle, a sliding section formed in the longitudinal direction of the vehicle, and a second pop-up section formed in an arc shape and connecting the outer end of the first pop-up section and one end of the sliding section.

[0013] In the vehicle sliding door switch device, when the pair of links moves along the bracket, the pair of rollers can rotate the pair of links while moving in the first pop-up section and the second pop-up section, thereby popping out the sliding door.

[0014] In a vehicle sliding door switch device, a pair of rollers may rotate more when the rollers move in a first pop-up section than when they move in a second pop-up section.

[0015] In the vehicle sliding door switch device, when the roller moves in the sliding section, in order to keep the sliding door in a popped-up state, a pair of links may not rotate further.

[0016] In the vehicle sliding door switch device, the pair of links may include a first link and a second link arranged to be spaced apart in a longitudinal direction of the vehicle, and the roller may be mounted on the other end of the first link.

[0017] In the vehicle sliding door switch device, when the sliding door is closed, the roller may be positioned further toward the front of the sliding door than the first link rotation axis of the first link in the sliding direction.

[0018] In the vehicle sliding door opening and closing device, the moving guide may be formed to have a concave cross-section, whereby the roller may be positioned and moved inside the moving guide.

[0019] The vehicle sliding door opening and closing device may further include a guide rail mounted on the vehicle body along a longitudinal direction of the vehicle and a slider slidably mounted on the guide rail, the bracket being mounted on the slider.

[0020] In a vehicle sliding door switch device, a plurality of sliders may be provided and may be mounted on a bracket in a manner of being spaced apart from each other.

[0021] In a vehicle sliding door opening and closing device, a door frame may be mounted on the sliding door, and one end of each of a pair of links may be hinged to the door frame.

[0022] In a vehicle sliding door switch device, a bracket, a pair of connecting rods and a door frame may form a parallelogram four-link.

[0023] In a vehicle sliding door switch device, a door frame may be installed at an upper portion and a lower portion of the sliding door.

[0024] The vehicle sliding door switch device may also include: a drive motor mounted on the vehicle, a screw rotatably mounted on the vehicle to be arranged along the longitudinal direction of the vehicle, the screw being rotated by the drive motor, and a moving block connected to the screw in a nut-screw fastening manner, the moving block moving along the axial direction of the screw and being fastened to the bracket when the screw is tightened, wherein when the drive motor is rotated, the bracket can move along the longitudinal direction of the vehicle.

[0025] In the vehicle sliding door switch device according to the embodiment of the present invention having the above-mentioned configuration, both the upper and lower parts of the sliding door slide in a supported state. Therefore, even if the center rail is not used, the sliding door can be stably operated.

[0026] Since the center rail is not used, the problem of deterioration in the appearance quality of the vehicle due to installation of the center rail on the side of the vehicle can be prevented.

[0027] In addition, the space for the sliding door opening and closing operation inside the vehicle body is minimized. Therefore, the interior space and the space for installing the battery can be further expanded. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Hereinafter, a vehicle sliding door switch device 20 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0038] According to an embodiment of the present invention, a vehicle sliding door switch device 20 may include: a bracket 23 slidably mounted along the longitudinal direction of the vehicle 1; a pair of connecting rods 21, 22 rotatably mounted on the bracket 23 and spaced apart from each other, one end of the pair of connecting rods 21, 22 being hinged to the sliding door 12 of the vehicle 1; and a pop-up unit, which is used to rotate the pair of connecting rods 21, 22 in the initial stage of opening the sliding door 12 so that the sliding door 12 pops out from the body 11 of the vehicle 1.

[0039] Figure 1 and Figure 2 2 shows a vehicle 1 using the vehicle sliding door switch device 20 according to the embodiment of the present invention.

[0040] The sliding door 12 may be installed at a side of the body 11 of the vehicle 1 along the longitudinal direction of the vehicle 1. The sliding door 12 may be opened to allow passengers to enter and exit the cabin of the vehicle 1 or to load and unload cargo into and from the vehicle 1.

[0041] Here, the vehicle 1 may include a private vehicle (PBV). Most PBVs may be implemented as electric vehicles. In order to utilize the interior space or for other purposes, the vehicle 1 as a PBV may be configured so that the side of the vehicle 1 is opened as wide as possible. To this end, the sliding door 12 may be installed on the side of the vehicle body 11 in a manner of opening and closing in opposite directions.

[0042] The vehicle sliding door opening and closing device 20 according to the embodiment of the present invention may be installed on the inner surface of the sliding door 12 so that the sliding door 12 is opened and closed along the side of the vehicle 1 .

[0043] The bracket 23 may be mounted on the vehicle body 11 in a manner that it can slide along the longitudinal direction of the vehicle 1. The bracket 23 needs to slide along the longitudinal direction of the vehicle 1. Therefore, the bracket 23 may be mounted via the guide rail 25 and the slider 26, rather than being directly mounted on the vehicle body 11.

[0044] The guide rail 25 may be fixedly installed along the longitudinal direction of the vehicle body 11. The slider 26 may be slidably installed on the guide rail 25. The bracket 23 may be installed on the slider 26.

[0045] An LM guide is preferably used as the guide rail 25. Accordingly, friction can be reduced when the sliding door 12 is opened and closed, whereby the sliding door 12 can also slide with a small force.

[0046] The bracket 23 can be assembled to the slider 26 at multiple points thereon. Thus, the bracket 23 can slide stably.

[0047] The plurality of connecting rods 21, 22 may interconnect the bracket 23 and the sliding door 12. The connecting rods 21, 22 may enable the sliding door 12 to pop out at the initial stage of opening the sliding door 12, occupying less space, and maintain its pop-out state during the sliding operation. Accordingly, the space required for passengers to enter and exit the vehicle 1 and the battery installation space may be further ensured.

[0048] The door frame 12 a may be installed on the inner surface of the sliding door 12 so that the connecting rods 21 , 22 are connected to the sliding door 12 .

[0049] The connecting rods 21 and 22 may be arranged in pairs, one of which is the first connecting rod 21 and the other is the second connecting rod 22. The first connecting rod 21 and the second connecting rod 22 spaced apart from each other may be hinged to the bracket 23 and the door frame 12a. That is, the middle portion of the first connecting rod 21 may be hinged to the bracket 23 in a manner rotatable around the first connecting rod rotation axis L1, and one end thereof may be connected to the door frame 12a with the first connecting rod door frame rotation axis B1 as a hinge axis. The second connecting rod 22 may also be connected to the bracket 23 in a manner rotatable around the second connecting rod rotation axis L2, and one end of the second connecting rod may be hinged to the door frame 12a with the second connecting rod door frame rotation axis B2 as a hinge axis.

[0050] The length between the hinged parts of the first link 21 and the second link 22 on the bracket 23 is the same as the length between the hinged parts of the first link 21 and the second link 22 on the door frame 12a. Figure 4 In the embodiment, the length between the first link rotation axis L1 and the second link rotation axis L2 may be the same as the length between the first link gantry rotation axis B1 and the second link gantry rotation axis B2. In addition, the first link 21 and the second link 22 may be formed in such a manner that they have equal lengths from their respective rotation centers (where they are hinged to the bracket 23) to their respective other ends (where they are hinged to the gantry 12a). That is, in Figure 4 In the embodiment, the length between the first link rotation axis L1 and the first link gantry rotation axis B1 may be the same as the length between the second link rotation axis L2 and the second link gantry rotation axis B2.

[0051] The bracket 23, the first link 21, the second link 22 and the door frame 12a can form a parallelogram of four joints. Accordingly, the sliding door 12 can be popped out from the side of the vehicle body 11 by a predetermined distance. Then, the sliding door 12 can slide along the longitudinal direction of the vehicle 1 in its popped-out state.

[0052] The sliding door 12 may be located in the same line as the side of the vehicle 1 in the closed state. However, the sliding door 12 needs to be spaced apart from the outer surface of the vehicle body 11 by a predetermined distance when sliding to open and close. For this purpose, a pop-up unit may be provided. The pop-up unit may pop the sliding door 12 out of the vehicle body 11 by rotating the first link 21 and the second link 22 at the beginning of the opening operation of the sliding door 12. In addition, the pop-up unit may rotate the first link 21 and the second link 22 in the opposite direction to the direction in which the first link 21 and the second link 22 are rotated when the sliding door 12 is opened at the end of the closing operation of the sliding door 12, thereby enabling the sliding door 12 to be located in the same line as the vehicle body 11.

[0053] To this end, the ejection unit may include a roller 21 a mounted on the other end portion of the first link 21 and a moving guide 24 guiding a trajectory of the roller 21 a.

[0054] The roller 21 a may be rotatably installed on the other end portion of the first link 21 .

[0055] The moving guide 24 may accommodate the roller 21a therein. The other end of the first link 21 moving with the bracket 23 may move the moving guide 24, thereby rotating the first link 21. The first link 21 may rotate in this manner, whereby the sliding door 12 may be operated to pop out from the vehicle body 11 or retract therein.

[0056] The moving guide 24 may be formed to have a concave cross-section, whereby the roller 21 a may be located inside the moving guide 24 .

[0057] In the early stage of the opening operation of the sliding door 12, the moving guide 24 can rotate the first link 21 to pop up the sliding door 12 in the early stage of the opening operation of the sliding door 12, or can prevent the first link 21 from rotating while the sliding door slides to open and close. The moving guide 24 can have a profile including a first pop-up section S1, a second pop-up section S2, and a sliding section S3, for guiding the sliding door 12 to slide after popping out. That is, the first pop-up section S1 of the moving guide 24 can be formed along the lateral direction of the vehicle 1, the sliding section S3 can be formed along the longitudinal direction of the vehicle 1, and the second pop-up section S2 can be formed in an arc shape and connect the outer side end of the first pop-up section S1 and one end of the sliding section S3. If the roller 21a is located in the first pop-up section S1 and the second pop-up section S2, the relative position of the first link rotation axis L1 of the first link 21 and the roller 21a can change, and the first link 21 can be rotated accordingly.

[0058] When the bracket 23 slides in the longitudinal direction of the vehicle 1, the roller 21a may move in the first pop-up section S1. As a result, the first link 21 may also rotate, so that the sliding door 12 in the closed state is partially popped out.

[0059] Thereafter, the bracket 23 may move in the second pop-up section S2 while continuing to slide. As a result, the first link 21 may rotate, thereby completing the pop-up of the sliding door 12. The rotation amount of the first link 21 when the roller 21a moves in the first pop-up section S1 may be greater than the rotation amount of the first link 21 when the roller 21a moves in the second pop-up section S2. As a result, the pop-up amount of the sliding door 12 may also be greater.

[0060] When the pop-up of the sliding door 12 is completed, and thus the roller 21a moves in the sliding section S3, the relative positions of the first link rotation axis L1 of the first link 21 and the roller 21a may not be changed. As a result, the first link 21 may not rotate. Accordingly, the second link 22 and the door frame 12a may not rotate relative to each other. As a result, the sliding door 12 may maintain its pop-up state. In this state, the bracket 23 may move, and thus the sliding door 12 may slide to open and close.

[0061] The second link 22 may form a parallelogram four-link with the first link 21, the bracket 23 and the door frame 12a. As a result, the second link 22 may move like the first link 21. Therefore, when the roller 21a is mounted on the first link 21 and the roller 21a moves on the moving guide 24, the roller 21a and the moving guide 24 may not affect the operation of the second link 22.

[0062] In addition, the roller 21 a and the moving guide 24 may be installed along the direction of the second link 22 instead of the first link 21 .

[0063] In order to automatically close and open the sliding door 12 , a driving motor 27 , which outputs a rotational force when powered, may be installed, whereby the bracket 23 may be moved.

[0064] The driving motor 27 may be installed at one side of the vehicle body 11 and may output a rotational force when powered. The driving motor 27 may rotate in opposite directions when the sliding door 12 is opened and closed.

[0065] The screw 28 may be rotatably mounted on the vehicle 1 in a manner arranged along the longitudinal direction of the vehicle 1. The screw 28 may be rotated by the drive motor 27. One end of the screw 28 may be connected to the drive motor 27, and the other end thereof may be supported on a screw seat 28a mounted on the vehicle body 11.

[0066] The moving block 29 may be coupled to the screw rod 28 in a nut-screw fastening manner. The moving block 29 may be fastened to the bracket 23. The moving block 29 and the bracket 23 may be fastened to each other using a fastening unit 23a formed on one side of the bracket 23 in a bent form.

[0067] The connection between the screw rod 28 and the moving block 29 can convert the rotational motion of the screw rod 28 into the linear motion of the moving block 29. The linear motion of the moving block 29 can move the bracket 23 in the longitudinal direction of the vehicle 1, thereby sliding the sliding door 12 in the longitudinal direction of the vehicle 1.

[0068] If the driving motor 27, the screw rod 28, and the moving block 29 are not installed, the sliding door 12 may be installed to be opened and closed.

[0069] The vehicle sliding door switch device 20 constructed as above can be installed at the upper and lower parts of the sliding door 12, respectively, so that the sliding door 12 can be opened and closed by respectively guiding the upper and lower parts of the sliding door 12. The door frame 12a can be installed at the upper and lower parts of the sliding door 12, respectively. Using the door frame 12a, the vehicle sliding door switch device 20 can be connected to the sliding door 12.

[0070] However, the driving motor 27, the screw rod 28 and the moving block 29 may be installed at one of the upper and lower parts of the sliding door 12, preferably at the upper part of the sliding door 12. Accordingly, when the upper part of the sliding door 12 is operated, the lower part thereof may be operated along the same track as the upper part. Therefore, the sliding door 12 may be opened and closed.

[0071] In addition, if Figure 1 and Figure 2 As shown, in the case where a pair of sliding doors 12 are installed on one side of the vehicle 1, the vehicle sliding door switch devices 20 described above can be constructed to be symmetrical to each other, thereby being able to be used for the sliding doors 12 respectively.

[0072] The operation of the vehicle sliding door switch device 20 according to the embodiment of the present invention having the above configuration is described as follows.

[0073] Figure 6 The state where the sliding door 12 is closed is shown. In the state where the sliding door 12 is closed, the sliding door 12 and the vehicle body 11 may be arranged on the same line.

[0074] Figure 7 An initial pop-up state of the sliding door 12 is shown.

[0075] When a passenger operates a switch mounted on the vehicle 1 to open the sliding door 12 , the driving motor 27 may rotate, thereby rotating the screw 28 .

[0076] When the screw 28 moves the moving block 29 along the longitudinal direction of the screw 28 , the bracket 23 may also move along the guide rail 25 together with the moving block 29 .

[0077] When the bracket 23 starts to move in the longitudinal direction of the vehicle 1 , as the bracket 23 moves, the first link 21 and the second link 22 may also move together with the bracket 23 .

[0078] At this time, the roller 21a can move inside the moving guide 24. As a result, the first link 21 can rotate. The first link rotation axis L1 of the first link 21 can move along the moving block 29 along the longitudinal direction of the vehicle 1, and the roller 21a can move inside the moving guide 24. As a result, the first link 21 can rotate around the first link rotation axis L1. At this time, the first link 21 can rotate in a direction to move the sliding door 12 away from the vehicle body 11. The first link 21, the door frame 12a, the second link 22 and the bracket 23 can form a parallelogram of four links. As a result, when the first link 21 rotates around the bracket 23, the second link 22 can also rotate in the same direction as the first link 21. Therefore, the door frame 12a can be spaced apart from the bracket 23. Accordingly, the sliding door 12 can be ejected from the vehicle body 11.

[0079] From the closed state of the sliding door 12 to its initial open state, the roller 21a can move slightly toward the inner side of the vehicle 1 in the first pop-up section S1 of the moving guide 24. Figure 6 , the roller 21a may be positioned further toward the front of the sliding door 12 than the first link rotation axis L1 of the first link 21 in the sliding direction (the line A2 is located on the right side of the line A1). Figure 7As shown, when the first link 21 rotates while moving along the bracket 23, the first link rotation axis L1 of the first link 21 can be located on the same line as the roller 21a, and the center of the roller 21a can move slightly from point R1 to point R2 toward the inner side of the vehicle 1. Accordingly, this movement can limit the excessive extension of the sliding door 12 in the lateral direction of the vehicle 1.

[0080] Figure 8 The final state in which the sliding door 12 is ejected is shown.

[0081] As the drive motor 27 continues to rotate, the bracket 23 may move along the guide rail 25 in the longitudinal direction of the vehicle 1. As a result, the first link 21 and the second link 22 may also continue to move.

[0082] At this time, the first link 21 may also move toward the second ejection section S2 of the moving guide 24. As a result, the first link 21 may eject the sliding door 12 from the vehicle 1 while rotating about the first link rotation axis L1.

[0083] When the roller 21 a moves in the first and second pop-up sections S1 and S2 of the moving guide 24 , the sliding door 12 may also pop up in the lateral direction of the vehicle 1 while sliding in the longitudinal direction of the vehicle 1 .

[0084] Fig. 9 A state is shown in which the sliding door 12 slides after ejection is completed.

[0085] As the driving motor 27 rotates, the bracket 23 may continue to move along the guide rail 25. Thereafter, the first link 21 and the second link 22 may also move along the longitudinal direction of the vehicle 1.

[0086] The roller 21a can move along the sliding section S3 of the moving guide 24. As a result, the first link 21 and the second link 22 and the bracket 23 can move along the longitudinal direction of the vehicle 1 without further rotation. Therefore, the sliding door 12 can be fully opened at the side of the vehicle 1.

[0087] When the sliding door 12 moves a predetermined distance, the sliding door 12 may stop, thereby maintaining its open state. For example, a striker (not shown) mounted on the sliding door 12 may be hooked to a latch (not shown) mounted on the vehicle body 11 and thereby fixed thereto. As a result, the sliding door 12 may maintain its open state.

[0088] In order to close the sliding door 12, the above-mentioned operation of opening the sliding door 12 may be performed in reverse order. Accordingly, the sliding door 12 may be closed.

[0089] When the driving motor 27 rotates in the reverse direction, the other constituent elements may operate in the reverse direction to the opening direction of the sliding door 12. As a result, the sliding door 12 may be closed.
