[0032] As a specific embodiment of the present application, reference is made to Figure 1 , Figure 2 and Figure 3The sliding door opening device 100 of the embodiment can include a middle rail 10 fixedly connected at a vehicle body and two guide assemblies 20. The middle rail 10 fixedly connected at the vehicle body is in sliding cooperation with a hinge 30 fixedly connected at a vehicle door. The middle rail 10 can include a curved portion 101 extending from the vehicle door towards a middle position of the vehicle. The two guide assemblies 20 are used to guide a pull cable 40 for slidingly driving the hinge 30, each of the two guide assemblies 20 is arranged at a position close to one of the two ends of the middle rail 10, and part or all of the structure of the guide assembly 20 arranged at a position close to the end of the middle rail 10 is arranged between the two ends of the middle rail 10.

[0033] In the embodiment, the extension direction of the middle rail 10 is the front-rear direction of the vehicle, i.e., the X direction, and the curved portion 101 extends towards the inside of the vehicle, i.e., the curved portion extends towards the Y direction, i.e., the left-right direction of the vehicle. In the embodiment, part or all of the structure of the guide assembly 20 arranged at the end of the middle rail 10 close to the curved portion 101 is arranged between the two ends of the middle rail 10, so that the size of the entire opening device in the X direction and the Y direction, especially the size in the Y direction, can be effectively reduced, the size of the sliding door in the Y direction is saved, the space utilization is improved, and the comfort of the second-row passengers is improved.

[0034] In the embodiment, since one guide assembly 20 is arranged at each of the two ends of the middle rail 10, arranging one or both of the two guide assemblies 20 at a position between the two ends of the middle rail 10 can reduce the space in the X direction, and arranging the guide assembly close to the curved portion 101 at a position between the two ends of the middle rail 10 can save the space in the X direction and the space in the Y direction, so that the space for arranging the vehicle door body is relatively reduced, the space for arranging other components is increased, the space of the second row, the third row or the aisle is improved, and the user experience is improved. The space includes the size of the guide assembly 20 itself and the distance between the guide assembly 20 and the middle rail 10.

[0035] Specifically, in the actual center rail 10, generally speaking, the left end side is flat, and a curved structure (bend) is formed near the right end, and the guide assembly 20 at this position is hidden in the center rail 10. The guide assembly 20 near the left end is not set between the two ends of the center rail 10, which is not good for the appearance, so in this application, only the guide assembly 20 near the right end of the center rail 10 is set between the two ends of the center rail 10. The left end guide assembly can be selectively set between the two ends of the center rail 10 according to the actual vehicle requirements. When the left end guide assembly is set between the two ends of the center rail 10, its structure is consistent with that between the right end and the left end, and the improvement of the center rail 10 is consistent. The following is a specific description of only the guide assembly 20 near the right end of the center rail 10 being set between the two ends of the center rail 10.

[0036] As one of the specific embodiments, in this embodiment, the guide assembly 20 at the right end of the center rail 10 is set between the two ends of the center rail 10, which can save about 65-75 mm in the Y direction, for example, about 65 mm, 70 mm or 75 mm in the Y direction, thereby increasing the space of the second row of seats in the Y direction and improving the user experience.

[0037] As one of the specific embodiments of the present application, referring to Figure 4 , Figure 5 and Figure 6 , each guide assembly 20 of this embodiment can include a connecting plate 21 and a guide box 22. The connecting plate 21 is fixedly connected with the vehicle body. The guide box 22 is connected with the connecting plate 21, and the guide box 22 is located between the two ends of the center rail 10.

[0038] Specifically, the center rail 10 and the guide assembly 20 of this embodiment are fixedly connected with the vehicle body, and there is no connection relationship between the center rail 10 and the guide assembly 20, only a positional relationship. In this embodiment, the guide box 22 is fixedly connected with the vehicle body through the connecting plate 21. The guide box 22 is located between the two ends of the center rail 10. Thus, the space at the right end of the center rail 10 is saved, and the use of the guide assembly 20 is not affected.

[0039] As one of the specific embodiments of the present application, the center rail 10 of this embodiment is a hollow pipe, and a notch 11 extending from one end of the center rail 10 to the other end of the center rail 10 is arranged at the end position of the center rail 10, and the guide box 22 is arranged in the center rail 10 at the position of the notch 11.

[0040] As one of the specific embodiments of the present application, referring to Figure 7The middle rail 10 of the embodiment can include two oppositely arranged first groove edges 12 and two oppositely arranged second groove edges 13, each of the second groove edges 13 including a first part 131 and a second part 132, wherein the first part 131 of one of the second groove edges 13 is an opening 14 extending in a direction parallel to the direction in which the rail extends, and the notch 11 is arranged at the position of the second part 132 of the other of the second groove edges 13 of the middle rail 10.

[0041] Specifically, as shown in Figure 7 , the cross section of the middle rail 10 forms the first groove edges 12 arranged in parallel in the up-down direction and the second groove edges 13 arranged in the left-right direction, and the opening 14 is arranged below the second groove edges 13, which is used for placing and running the hinge and the guiding connecting component. The notch 11 is arranged above the right second groove edge 13. Since the guiding box 22 of the guiding structure needs to be arranged in the middle rail 10 in the embodiment, and the middle rail 10 mainly provides guidance for the hinge 30 (see Figure 8 ), the hinge 30 needs to move back and forth in the middle rail 10, so the guiding box 22 needs to be arranged above to avoid the position of the hinge 30.

[0042] As a specific embodiment of the present application, the size of the second part 132 of the second groove edge 13 of the embodiment is adapted to the size of the guiding box 22. The size of the second groove edge 13 is 60-65 mm. Specifically, the size of the second part 132 of the second groove edge 13 is increased by about 10-15 mm due to the need to arrange the guiding box 22. For example, the size can be increased by 10 mm, 12 mm, 13 mm or 15 mm.

[0043] As a specific embodiment of the present application, referring to Figure 5 , the guiding box 22 of the embodiment can include a hollow disc-shaped box body 221 and a roller 222 arranged inside the box body 221 and rotationally connected with the box body 221. The box body 221 is provided with an inlet 223 and an outlet 224 tangent to the circumferential direction of the box body 221, and the pull cable 40 enters the box body 221 through the inlet 223, is wound around the roller 222, and then extends out of the box body 221 through the outlet 224. The positions of the inlet 223 and the outlet 224 in the embodiment are schematic, and the positions thereof can be exchanged.

[0044] Specifically, in the embodiment, the pull cable 40 changes direction through the guiding box 22, so that the pull cable 40 can extend from the power end to the hinge 30 end.

[0045] Specifically, referring to Figure 1The sliding door opening device 100 in the embodiment can further include a driving motor 50 and a winding wheel 60. The driving motor 50 is connected with the winding wheel 60 and drives the winding wheel 60 to rotate. Then, the pulling rope 40 on the winding wheel 60 pulls the hinge 30 to slide in the middle rail 10 after passing through the roller 222.

[0046] Specifically, the winding wheel 60 is driven by the driving motor 50 to rotate. When rotating, the pulling rope 40 around the winding wheel 60 moves back and forth. The pulling rope 40 is connected with the hinge 30 through the guide assembly 20 at both ends. When the pulling rope 40 moves back and forth, the hinge 30 is pulled to move back and forth, thereby driving the sliding door to slide back and forth.

[0047] The design of the driving motor 50 and the winding wheel 60 in the embodiment can make the sliding door directly controlled by the electric control to open and close.

[0048] As a specific embodiment of the present application, the connecting plate 21 in the embodiment is a curved plate. A through hole parallel to the extending direction of the middle rail 10 is arranged at the connecting plate 21. The connecting plate 21 is connected with the guide box 22 at the position of the through hole.

[0049] Specifically, the connecting plate 21 in the embodiment is mainly related to the structure of other positions of the vehicle body. It can be curved or other shapes that can meet the requirements.

[0050] Part of the connecting plate 21 in the embodiment is parallel to the middle rail 10. The other part is bent at the end position of the middle rail 10. A through hole is arranged at the connecting plate 21. The guide box 22 is connected with the connecting plate 21 at the through hole.

[0051] As a specific embodiment of the present application, the middle rail 10 in the embodiment is formed in a curved shape near one end position. The part or all of the structure of the guide assembly 20 arranged near the end with the curved shape is located between the two end positions of the middle rail 10. The guide assembly 20 arranged near the other end is located outside the middle rail 10.

[0052] Specifically, the right end portion of the middle rail 10 is formed in a curved shape, so that the door can be moved in a curved position when the rail is moved to the right end position, avoiding interference with other parts of the vehicle. In actual installation of the middle rail 10 in the vehicle, the curved shape is curved toward the inside of the vehicle, so that the guide assembly 20 provided at the middle rail 10 can be hidden inside. The left end portion of the middle rail 10 is a straight rail, so that the guide assembly 20 located at the left end portion is not provided at the middle rail 10, avoiding the partial structure of the guide assembly 20 from being seen from the rail, and thus, as one embodiment, the guide assembly 20 located at the left end portion is provided at the left side of the middle rail 10. In this way, the Y-direction space can be saved without affecting the appearance.

[0053] As one embodiment of the present application, the present embodiment provides a vehicle which can include the sliding door opening device 100 described above.

[0054] It will thus be appreciated that those skilled in the art will be able to devise numerous other arrangements without departing from the scope of the present application as defined by the appended claims, wherein claims, the embodiments disclosed in this specification and drawings are to be considered in all respects as illustrative only and not restrictive in character, so that only the claims are restrictive and that these are to be given their broadest interpretation.
