In such a structure using multiple guide rails, the multiple guide rails are generally connected in parallel, and there is inevitably a gap or surface difference between two adjacent guide rails. Therefore, when the roller of the hinge mechanism slides from one guide rail to another, obvious vibration or abnormal sound will be generated due to the surface difference of the guide rail surface or the gap between the two guide rails, resulting in a poor customer experience. Utility Model Content
[0003] The utility model is made in view of the above problems, and its purpose is to provide a guide rail assembly and a sliding door sliding structure having the guide rail assembly, which can make the roller slide smoothly from one guide rail to another and reduce the vibration or abnormal sound when the roller is transferred.
[0004] In order to achieve the above-mentioned purpose, a guide rail assembly of one embodiment of the utility model comprises: a plurality of guide rails, which are connected in sequence, and rollers connected to the sliding door of the vehicle roll in sequence on the plurality of guide rails; and a plurality of transition components, which are arranged on a first guide rail which is one of two adjacent guide rails, and are arranged in a manner of spanning the first guide rail and a second guide rail which is the other of the two adjacent guide rails, and when the roller is transferred between the first guide rail and the second guide rail, at least a portion of the roller rolls on the transition component.
[0005] According to such a structure, when the roller is transferred between the first guide rail and the second guide rail through the transition member, even if there is a gap or surface difference between the two guide rails, the roller can not contact the edge between the first guide rail and / or the second guide rail. Therefore, the vibration of the roller caused by the gap or surface difference between the first guide rail and the second guide rail can be prevented, and the roller can be transferred between the first guide rail and the second guide rail more smoothly, thereby improving the user experience.
[0006] In the guide rail assembly of the present invention, the transition member may be a tongue protruding from the first guide rail to the second guide rail, and the second guide rail is provided with a groove for inserting the tongue, and the axial width of the groove of the roller is smaller than the axial width of the roller.
[0007] According to such a structure, the roller can be supported by the two edges of the groove so that the roller can be smoothly transferred between the second guide rail and the tongue piece, thereby further eliminating the vibration of the roller and further improving the user experience.
[0008] In the above-mentioned guide rail assembly, preferably, the tongue piece has a transition portion whose height gradually decreases toward the second guide rail, one end of the transition portion close to the second guide rail is lower than the surface of the second guide rail for the roller to roll, and the other end of the transition portion close to the first guide rail is not lower than the surface of the second guide rail, and when the tongue piece is inserted into the groove, the other end is located in the groove.
[0009] According to such a structure, the roller can contact with the other end of the transition part or leave from the other end of the transition part within the range of the groove. Thus, the height difference caused by the roller contacting the tongue outside the groove can be prevented, and the roller can be transferred between the groove and the tongue more smoothly.
[0010] In the above-mentioned guide rail assembly, preferably, the tongue also has a connecting portion connecting the transition portion and the first guide rail, a part of the connecting portion is located in the groove, the height of the connecting portion is the same as the height of the other end of the transition portion, and there is a smooth transition between the connecting portion and the other end.
[0011] According to such a structure, the roller can be transferred between the tongue piece and the first guide rail more smoothly.
[0012] In the above-mentioned guide rail assembly, preferably, the tongue also has an extension portion extending from the connecting portion to the opposite side of the transition portion on the first guide rail, and the roller rolls on the extension portion after being transferred to the first guide rail. A rolling panel for the roller to roll on is provided on the second guide rail and extends along the second guide rail, and the groove is provided on the rolling panel.
[0013] According to such a structure, during manufacturing, it is only necessary to connect the tongue piece to the surface of the first guide rail. Compared with the method of setting the tongue piece on the edge of the first guide rail, the step of aligning the connecting portion with the edge of the first guide rail can be omitted, so that manufacturing can be facilitated. In addition, by providing a rolling panel for the roller to roll on the second guide rail, during manufacturing, it is only necessary to make a groove on the rolling panel and attach the rolling panel with the groove to the surface of the second guide rail. In this way, the manufacturing efficiency of the second guide rail 12 can be improved.
[0014] In the above-mentioned guide rail assembly, preferably, the axial width of the roller of the groove gradually narrows as it moves away from the first guide rail.
[0015] According to such a structure, when the roller rolls from the groove toward the surface of the second guide rail, the roller can gradually rise along the two edges of the groove, thereby alleviating the vibration when the roller transfers to the surface of the second guide rail and improving the user experience.
[0016] In the above-mentioned guide rail assembly, preferably, the end portion of the groove away from the first guide rail is in an arc shape curved in a direction away from the first guide rail.
[0017] According to such a structure, the roller can move smoothly from the groove to the surface of the second guide rail, reducing the vibration of the roller when transferring from the groove to the surface of the second guide rail, thereby further improving the user experience.
[0018] In the guide rail assembly of the present invention, the transition member can also be a seesaw arranged on the outside of the first guide rail in the width direction and capable of rotating around an axis portion arranged on the first guide rail, the roller includes a main wheel and a secondary wheel arranged coaxially, the diameter of the secondary wheel is smaller than the diameter of the main wheel, and is arranged on the side of the main wheel facing the seesaw, when the roller transfers from the second guide rail to the first guide rail, the secondary wheel rolls on the seesaw, so that the seesaw rotates in the direction of the first guide rail due to the gravity of the secondary wheel.
[0019] According to such a structure, since a seesaw and a secondary wheel are provided, when the roller transfers between the first guide rail and the second guide rail, the seesaw can be used to lift the roller to prevent the roller from contacting the edges of the ends of the two guide rails, thereby preventing the vibration of the roller caused by the gap and surface difference between the two guide rails, and enabling the roller to transfer more smoothly between the first guide rail and the second guide rail, thereby improving the user experience.
[0020] In the above-mentioned guide rail assembly, it is preferred that a biasing member is provided on the shaft portion, and the biasing member biases the seesaw in a direction to rotate the seesaw toward the second guide rail.
[0021] According to such a configuration, the rocker can be reset in a simple manner when the secondary wheel is not in contact with the rocker.
[0022] In the above-mentioned guide rail assembly, it is preferred that a limiting portion is provided on the same side of the first guide rail in the width direction as the seesaw, at the shaft portion or at a position closer to the second guide rail than the shaft portion, and the limiting portion limits the further rotation of the seesaw in the direction of the force applied by the force-applying component by abutting against the seesaw, so that when the secondary wheel just contacts the seesaw, the projection of the axis of the rotating shaft of the roller on the surface of the second guide rail for the roller to roll is located within the second guide rail.
[0023] According to such a structure, the seesaw can be prevented from excessively rotating, and the secondary wheel can be ensured to smoothly ride on the seesaw. In addition, it can be ensured that the roller is lifted by the seesaw when passing through the gap between the first guide rail and the second guide rail, and the main wheel of the roller is prevented from contacting the edge of the end of the guide rail to generate vibration and abnormal sound.
[0024] In addition, a sliding door sliding structure according to one embodiment of the present invention comprises the above-mentioned guide rail assembly; and a hinge mechanism, one end of which is connected to the sliding door, and the other end of which has a load-bearing wheel serving as the roller.

[0050] (First Embodiment)
[0051] Reference Figures 1 to 4 , the guide rail assembly of the first embodiment is described. Figures 1 to 4 In the figure, (a) is a top view when the roller 14 is viewed from above, (b) is a cross-sectional view along the line AA in (a), and (c) is a cross-sectional view along the line B1-B1, line B2-B2, line B3-B3, and line B4-B4 in (a). Figure 2 (d) is Figure 2 The enlarged view of the dotted line part in (c) is Figure 3 (d) is Figure 3 An enlarged view of the dotted line portion in (c).
[0052] like Figure 1 As shown in (a), the guide rail assembly of the first embodiment comprises: a first guide rail 11 and a second guide rail 12 connected in sequence, and a tongue piece 13 as a transition member of the utility model, which is arranged on the first guide rail 11 and is arranged in a manner that straddles the first guide rail 11 and the second guide rail 12.
[0053] Specifically, if Figure 1 As shown, the tongue piece 13 has: a transition portion 131 whose height gradually decreases toward the second guide rail 12, a connection portion 132 connecting the transition portion 131 and the first guide rail 11, and an extension portion 133 extending from the connection portion 132 to the opposite side of the transition portion 131 on the first guide rail 11. In addition, a rolling panel 17 for the roller 14 to roll is installed on the second guide rail 12, and the rolling panel 17 extends along the second guide rail 12 and has a certain height. One end 1311 of the transition portion 131 of the tongue piece 13 is lower than the surface of the rolling panel 17, and the other end 1312 of the transition portion 131 is higher than the surface of the rolling panel 17. In addition, the height of the connection portion 132 is the same as the height of the other end 1312 of the transition portion 131, and there is a smooth transition between the connection portion 132 and the other end 1312 of the transition portion 131.
[0054] The second guide rail 12 is provided with a groove 121 for the tongue piece 13 to be inserted into. Figure 2As shown, the groove 121 is provided on the rolling panel 17, and the axial width of the roller 14 of the groove 121 is smaller than the axial width of the roller 14. Figure 1 As shown in (a), the axial width of the roller 14 of the groove 121 gradually narrows as it moves away from the first guide rail 11. In addition, the end of the groove 121 away from the first guide rail 11 is in an arc shape that is curved in a direction away from the first guide rail 11. Figure 1 As shown in (b), when the tongue piece 13 is inserted into the groove 121 , the other end 1312 of the transition portion 131 is located in the groove 121 , and a part of the connecting portion 132 is located in the groove 121 .
[0055] Reference Figures 1 to 4 The operation of the roller in the first embodiment will be described.
[0056] Figure 1 It indicates the state where the roller 14 rolls on the surface of the rolling panel 17 of the second guide rail 12. Figure 2 As shown in (c) and (d), when the roller 14 rolls from the second guide rail 12 to the top of the groove 121, the roller 14 is supported by the two edges of the groove 121 because the axial width of the roller 14 in the groove 121 is smaller than the axial width of the roller 14. At this time, the roller 14 has not yet contacted the transition portion 131, so the roller 14 is Figure 1 The state where the central point contacts the rolling panel 17 and rolls becomes Figure 2 The state in which the left and right sides of the vehicle are in contact with the rolling panel 17 and rolling.
[0057] When the roller 14 further rolls toward the first guide rail 11, Figure 3 As shown, the roller 14 is in contact with the transition portion 131 while being supported by the two edges of the groove 121, and is in contact with the transition portion 131 and the rolling panel 17 at three locations, namely, one in the center and two in the left and right. Then, as the roller 14 continues to roll, the roller 14 moves upward along the transition portion 131 and is no longer supported by the two edges of the groove 121, and is in contact with the transition portion 131 at one location in the center and rolls.
[0058] As the roller 14 moves further, Figure 4 As shown, the roller 14 passes through the connecting portion 132 and further moves to the extending portion 133, thereby completing the transfer from the second guide rail 12 to the first guide rail 11. After being transferred to the first guide rail 11, the roller 14 rolls on the extending portion 133.
[0059] In addition, when the roller 14 is transferred from the first guide rail 11 to the second guide rail 12, contrary to the above process, the roller 14 passes through the connecting portion 132 and the transition portion 131 in sequence, and then becomes a state of being supported by the two edges of the groove 121, and then contacts the arc-shaped end of the groove 121 and enters the surface of the rolling panel 17 of the second guide rail 12.
[0060] As described above, in this embodiment, since the tongue piece 13 is provided, when the roller 14 transfers between the first guide rail 11 and the second guide rail 12, even if there is a gap or a surface difference between the two guide rails, the roller 14 can roll on the tongue piece 13 without contacting the edge of the end of the first guide rail 11 and / or the second guide rail 12. Therefore, the tongue piece 13 can prevent the vibration of the roller 14 caused by the gap or the surface difference between the first guide rail 11 and the second guide rail 12, and the roller 14 can transfer between the first guide rail 11 and the second guide rail 12 more smoothly, thereby improving the user experience.
[0061] In addition, since a groove 121 for inserting the tongue 13 is provided in the second guide rail 12, and the axial width of the roller 14 of the groove 121 is smaller than the axial width of the roller 14, the roller 14 can be supported by the two edges of the groove 121 so that the roller 14 can be smoothly transferred between the second guide rail 12 and the tongue 13, thereby further eliminating the vibration of the roller 14.
[0062] In addition, the axial width of the roller 14 of the groove 121 gradually narrows as it moves away from the first guide rail 11. Therefore, when the roller 14 rolls from the groove 121 toward the surface of the rolling panel 17 of the second guide rail 12, the roller 14 can gradually rise along the two edges of the groove 121, thereby alleviating the vibration when the roller 14 is transferred to the surface of the rolling panel 17 of the second guide rail 12, thereby improving the user experience.
[0063] In addition, since the end of the groove 121 away from the first guide rail 11 is in an arc shape curved in the direction away from the first guide rail 11, the roller 14 can move smoothly from the groove 121 to the surface of the rolling panel 17 of the second guide rail 12, thereby alleviating the vibration of the roller 14 when transferring from the groove 121 to the surface of the rolling panel 17 of the second guide rail 12, thereby further improving the user experience.
[0064] In addition, one end 1311 of the transition portion 131 is lower than the surface of the rolling panel 17 of the second guide rail 12 on which the roller 14 rolls, and the other end 1312 of the transition portion 131 is higher than the surface of the rolling panel 17 of the second guide rail 12, and the other end 1312 of the transition portion 131 is located in the groove 121. Therefore, the roller 14 can contact with the other end 1312 of the transition portion 131 within the range of the groove 121, or leave from the other end 1312 of the transition portion 131, thereby preventing the height difference caused by the roller 14 contacting the tongue piece 13 outside the groove 121, and allowing the roller 14 to transfer between the groove 121 and the tongue piece 13 more smoothly.
[0065] In addition, the tongue piece 13 further includes a connecting portion 132 connecting the transition portion 131 and the first guide rail 11, a portion of the connecting portion 132 is located in the groove 121, and the height of the connecting portion 132 is the same as the height of the other end 1312 of the transition portion 131. Therefore, the roller 14 can be transferred between the tongue piece 13 and the first guide rail 11 more smoothly.
[0066] In addition, the tongue piece 13 also has an extension portion 133 extending from the connection portion 132 to the opposite side of the transition portion 131 on the first guide rail 11, and the roller 14 rolls on the extension portion 133 after being transferred to the first guide rail 11. Therefore, during manufacturing, it is only necessary to connect the tongue piece 13 to the surface of the first guide rail 11. Compared with the method of providing the tongue piece 13 on one side of the end of the first guide rail 11, the step of aligning the connection portion 132 with the surface of the first guide rail 11 can be omitted, so that manufacturing can be facilitated.
[0067] In addition, a rolling panel 17 for the roller 14 to roll is provided on the second guide rail 12. Therefore, during manufacturing, it is only necessary to make a groove 121 on the rolling panel 17 and attach the rolling panel 17 with the groove 121 to the surface of the second guide rail 12. In this way, the manufacturing efficiency of the second guide rail 12 can be improved.
[0068] (Second Embodiment)
[0069] Reference Figure 5 to Figure 7 , the guide rail assembly of the second embodiment is described. Figure 5 to Figure 7 In the figure, (a) is a side view observed from the axial direction of the roller 14', and (b) is a top view observed from above in (a).
[0070] like Figure 5As shown in (a), the guide rail assembly of this embodiment does not have the tongue 13 in the above-mentioned first embodiment. Instead, a seesaw 15 which also serves as a transition member is provided on the outer side of the first guide rail 11 in the width direction, and the seesaw 15 can rotate around the shaft 16 provided on the first guide rail 11. In addition, the roller 14' in this embodiment includes a main wheel 141 and a secondary wheel 142 which are coaxially arranged. The diameter of the secondary wheel 142 is smaller than the diameter of the main wheel 141, and is provided on the side of the main wheel 141 facing the seesaw 15. The seesaw 15 is arranged so that when the roller 14' is transferred from the second guide rail 12 to the first guide rail 11, the secondary wheel 142 rolls on the seesaw 15, so that the seesaw 15 rotates in the direction of the first guide rail 11 due to the gravity of the secondary wheel 142.
[0071] Although not shown in the figure, a force applying member such as a torsion spring is provided on the shaft portion 16, and the force applying member applies force to the seesaw 15 in a direction to rotate the seesaw 15 toward the second guide rail 12. A limit portion is provided on the same side as the seesaw 15 in the width direction of the first guide rail 11, and the limit portion can limit the seesaw 15 from further rotating in the direction of the force applying member by contacting the seesaw 15, so that the seesaw 15 can rotate in the direction of the force applying member. Figure 5 As shown, when the secondary wheel 142 just contacts the rocker 15, the projection of the axis O of the rotation axis of the roller 14' on the surface of the second guide rail 12 for the roller 14' to roll is located inside the second guide rail 12. The specific structure and installation position of the limiter are not particularly limited, for example, it can be integrally provided with the shaft portion 16, or it can be provided on a side closer to the second guide rail 12 than the shaft portion 16.
[0072] The operation of the roller 14 ′ according to the present embodiment will be described.
[0073] When the roller 14' is located at a position of the second guide rail 12 away from the seesaw 15, the seesaw 15 is in a position where the force-applying member and the limiting portion are in a position where the force-applying member and the limiting portion are in a position where the seesaw 15 is ... seesaw 15 is in a position where the Figure 5 The state shown in (a).
[0074] When the roller 14' rolls toward the first guide rail 11, Figure 5 When the secondary wheel 142 shown in (a) is in contact with the rocker 15 and further rolls toward the first guide rail 11, as shown in Figure 6 As shown, the roller 14 ′ is lifted by the rocker 15 , so that the main wheel 141 is not in contact with the first guide rail 11 or the second guide rail 12 .
[0075] When the roller 14 'is Figure 6 When the state further rolls toward the first guide rail 11, as Figure 7As shown, the seesaw 15 rotates toward the first rail 11 due to the gravity of the secondary wheel 142, and the roller 14' continues to roll along the seesaw 15 to the position where the main wheel 141 contacts the first rail 11. Then, the main wheel 141 rolls along the first rail 11, and the seesaw 15 remains in contact with the secondary wheel 142 due to the force application component.
[0076] In this embodiment, Figure 7 In the state shown, the main wheel 141 or the bracket on which the main wheel 141 is mounted is locked to the first guide rail 11 by a locking mechanism (not shown) disposed on the first guide rail 11, so that the roller 14' can be kept in a Figure 7 so that the roller 14' will not move further to the position where the secondary wheel 142 is separated from the rocker 15.
[0077] On roller 14' Figure 7 In the state shown, when transferring from the first guide rail 11 to the second guide rail 12, in contrast to the above process, the secondary wheel 142 of the roller 14' rolls on the seesaw 15, and when the roller 14' passes through the gap between the first guide rail 11 and the second guide rail 12, the main wheel 141 does not contact the first guide rail 11 or the second guide rail 12. Then, when the roller 14' moves to a position where the projection of the main axis is located on the second guide rail 12 and continues to roll, the main wheel 141 contacts the second guide rail 12, and the secondary wheel 142 is separated from the seesaw 15. Under the action of the force-applying member, the seesaw 15 abuts against the above-mentioned limiting portion provided on the first guide rail 11 and stops rotating.
[0078] As described above, in this embodiment, since the seesaw 15 and the secondary wheel 142 are provided, when the roller 14' is transferred between the first guide rail 11 and the second guide rail 12, the seesaw 15 can be used to lift the roller 14' to prevent the roller 14' from contacting the edges of the ends of the two guide rails, thereby preventing the vibration of the roller 14' caused by the gap and surface difference between the two guide rails, and enabling the roller 14' to transfer more smoothly between the first guide rail 11 and the second guide rail 12.
[0079] In addition, a force applying member is provided on the shaft 16, so that the seesaw 15 can be reset in a simple manner when the secondary wheel 142 is not in contact with the seesaw 15. In addition, by providing a limiter, the seesaw 15 can be prevented from excessively rotating, ensuring that the secondary wheel 142 can smoothly ride on the seesaw 15.
[0080] In addition, when the secondary wheel 142 just contacts the seesaw 15, the projection of the rotating axis of the roller 14' on the rolling surface of the second guide rail 12 for the roller 14' is located inside the second guide rail 12, thereby ensuring that the roller 14' is lifted by the seesaw 15 when passing through the gap between the first guide rail 11 and the second guide rail 12, thereby preventing the main wheel 141 of the roller 14' from contacting the edge of the end of the guide rail to generate vibration and abnormal noise.
[0081] Reference Figure 8 , an example of a sliding door sliding structure using the guide rail assembly of the utility model is described.
[0082] like Figure 8 As shown, the sliding door sliding structure has a hinge mechanism 2, one end of which is connected to the sliding door not shown in the figure, and the other end has a load-bearing wheel as the roller in the utility model. In the sliding door sliding structure, the second guide rail 12 is fixed to the body of the vehicle, and the first guide rail 11 extends in the door opening direction between the second guide rail 12 and the body. After the load-bearing wheel is transferred from the second guide rail 12 to the first guide rail 11 via the transition member, the first guide rail 11 can further slide along the second guide rail 12 in the door opening direction driven by the load-bearing wheel. In order to clearly show the first guide rail 11, the second guide rail 12 and the hinge mechanism 2, Figure 8 The display of transition components is omitted.
[0083] As mentioned above, although the preferred embodiment of the present invention has been described, the present invention is not limited thereto, and various modifications are possible without departing from the spirit of the present invention.
[0084] The first and second embodiments above describe the guide rail assembly having the first guide rail 11 and the second guide rail 12, but are not limited thereto. The guide rail assembly may also have a plurality of guide rails, which are sequentially connected, and the rollers roll on the plurality of guide rails sequentially.
[0085] When there are a plurality of guide rails, there may be a plurality of transition members provided on a first guide rail which is one of two adjacent guide rails and provided so as to straddle the first guide rail and a second guide rail which is the other of the two adjacent guide rails.
[0086] In addition, the transition member of the present invention is not limited to the tongue 13 and the seesaw 15 mentioned above, as long as at least a part of the roller rolls on the transition member when the roller transfers between the first guide rail 11 and the second guide rail 12, thereby avoiding colliding with the edge of the end of the guide rail.
[0087] In the first embodiment, the other end 1312 of the transition portion 131 is higher than the surface of the second guide rail 12 , but the present invention is not limited thereto.
[0088] In the first embodiment, the axial width of the roller 14 of the groove 121 gradually narrows as it moves away from the first guide rail 11, but the present invention is not limited thereto. The width of the groove 121 is not particularly limited and may be a constant width.
[0089] In the first embodiment, the end of the groove 121 away from the first guide rail 11 is an arc shape that is curved in a direction away from the first guide rail 11, but the invention is not limited thereto. The shape of the end of the groove 121 away from the first guide rail 11 is not limited as long as the vibration of the roller 14 when transferring to the second guide rail 12 can be alleviated.
[0090] In the first embodiment, the tongue piece 13 has the extension portion 133, and the roller 14 rolls on the extension portion 133 after being transferred to the first guide rail 11, but the invention is not limited thereto. The tongue piece 13 may not have the extension portion, but may be installed on one side of the end of the first guide rail 11 close to the second guide rail 12, and the connection portion 132 may be flush with the surface of the first guide rail 11. In the case where the extension portion is not provided, the rolling panel 17 may not be provided on the second guide rail 12.
[0091] In the second embodiment described above, the roller 14' is not further moved to the position where the secondary wheel 142 is separated from the seesaw 15 due to the action of the locking mechanism after the roller 14' is transferred to the first guide rail 11, but the invention is not limited thereto. For example, if the roller 14' needs to be further moved on the first guide rail 11 according to design requirements, the locking mechanism may not be provided, the seesaw may be designed to be bilaterally symmetrical, and the force-applying component on the shaft may be adjusted to a component capable of bidirectional force-applying.
[0092] As mentioned above, the guide rail assembly is applied to Figure 8 The sliding door sliding structure shown is described in the manner, but is not limited thereto. The guide rail assembly can also be applied to other forms of sliding door sliding structures, as long as there are multiple guide rails.
[0093] The present invention has been described above with reference to a specific example. However, the present invention is not limited to the specific example. A design obtained by a person skilled in the art by making appropriate design changes to the specific example is also included in the scope of the present invention as long as it has the features of the present invention.
