[0002] In the structural design of sliding doors, in order to arrange the rear slide rails, the sliding door must have a relatively long groove on the side wall. This groove is exposed during vehicle driving or parking. On the one hand, this groove is extremely easy to accumulate dirt, resulting in wear of the sliding door rollers during use; on the other hand, this groove is prone to generating gas eddies during high-speed driving, generating NVH noise and increasing vehicle energy consumption; at the same time, the appearance of this groove is exposed, which also greatly damages the overall appearance level of the vehicle.

[0003] In the prior art, such as a curtain-type sliding door guide rail groove shielding device and an automobile with a sliding door with the patent number CN204701428U, a guide rail groove is provided on the sliding door guide rail, a bracket is fixedly arranged inside the sliding door, and the guide rail groove is slidably matched with the bracket. The curtain-type sliding door guide rail groove shielding device includes: a roller blind device, the roller blind device includes a roller blind and a mandrel for fixedly arranging on the vehicle body, the roller blind is fixedly wound around the mandrel, and the roller blind includes a free end for fixedly connecting with the bracket. After the bracket pulls the free end to unfold the roller blind, the roller blind shields the guide rail groove. The curtain-type sliding door guide rail groove shielding device and the automobile with a sliding door provided by the present invention solve the problem of the exposure of the guide rail groove in the prior art, not only improving the safety performance, but also reducing the wind resistance coefficient of the whole vehicle, reducing fuel consumption, improving the working environment of the guide rail, and prolonging the service life of the guide rail.

[0004] However, in the prior art, a zipper structure is used, and a retractor is needed to retract the zipper to shield this sliding door groove. However, this structure has problems in the seam matching between the rear corner window glass and the zipper, and between the zipper and the side wall. It is easy to generate gaps between their mutual fittings, and air flow may flow in during high-speed driving to generate wind noise. On the other hand, the zipper structure is relatively soft and is also prone to generating abnormal noises during driving, which affects the NVH performance of the vehicle. Summary of the Invention

Detailed implementation manners

[0028] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0029] The embodiment of the present application provides a sliding door guide rail assembly and an automobile with a sliding door, which can solve the problem in the prior art that when using a zipper structure, a retractor is required to retract the zipper to cover the sliding door groove. However, there are problems with the seam matching between the rear corner window glass and the zipper, and between the zipper and the side wall. Gaps are likely to occur during their cooperation, and air flow may flow in during high-speed driving, generating wind noise. On the other hand, the zipper structure is relatively soft and is also prone to generating abnormal noises during driving, affecting the NVH performance of the vehicle.

[0030] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, on the one hand, the present application provides a sliding door guide rail assembly, which includes:

[0031] A sliding door guide rail 2, which is used to be arranged on the side wall body 1 and is located within the window opening range;

[0032] A rear corner window assembly 3, which includes a rear corner window guide groove 31, a rear corner window 32 and a driving mechanism 33. The rear corner window guide groove 31 is used to be arranged on the side wall body 1 and is located above the window opening. The upper end of the rear corner window 32 is used to extend into the rear corner window guide groove 31, and the driving mechanism 33 is used to drive the rear corner window 32 to move after the door is closed to cover the outside of the sliding door guide rail 2.

[0033] When installing the sliding door guide rail assembly, the sliding door guide rail 2 is used to be arranged on the side body 1 and located within the window opening range. The rear corner window guide groove 31 is used to be arranged on the side body 1 and located above the window opening. The upper end of the rear corner window 32 is used to extend into the rear corner window guide groove 31. The driving mechanism 33 is used to drive the rear corner window 32 to move after the vehicle door is closed, so as to cover the outside of the sliding door guide rail 2. Since after the vehicle door is closed, the driving mechanism 33 drives the rear corner window 32 to move to cover the outside of the sliding door guide rail 2, and before the vehicle door is opened, the driving mechanism 33 drives the rear corner window 32 to move to expose the sliding door guide rail 2, the structure added outside the side body 1 is reduced, the gaps are reduced, and thus the wind noise can be effectively reduced. It solves the problem in the prior art that when using a zipper structure, a retractor is needed to wind up the zipper to block this sliding door groove, but there are problems with the seam matching between the rear corner window glass and the zipper and between the zipper and the side body. Gaps are likely to be generated during their cooperation, and air flow may flow in during high-speed driving to generate wind noise. On the other hand, the zipper structure is relatively soft and is also likely to generate abnormal noises during driving, which affects the NVH performance of the vehicle.

[0034] In some optional embodiments, the rear corner window 32 is configured such that when the upper end of the rear corner window 32 is at the first design height, the rear corner window 32 blocks the sliding door guide rail 2, and when the upper end of the rear corner window 32 is at the second design height, the sliding door guide rail 2 is out of the projection range of the rear corner window 32 on the side body 1.

By adjusting the position in the height direction, the sliding door guide rail 2 can be blocked or exposed.

[0036] In some optional embodiments, the distance between the first design height and the second design height is less than the depth of the rear corner window guide groove 31.

[0037] In this embodiment, the distance between the first design height and the second design height is less than the depth of the rear corner window guide groove 31, that is, the upper end of the rear corner window 32 is always located within the rear corner window guide groove 31. When it is necessary to block the sliding door guide rail 2, the rear corner window 32 moves downward, and when it is necessary to expose the sliding door guide rail 2, the rear corner window 32 moves upward, which not only ensures the smoothness of the process of blocking the sliding door guide rail 2 but also reduces the movement range.

[0038] In this example, the depth of the rear corner window guide groove 31 is greater than or equal to the width of the sliding door guide rail 2 plus a reserved width, and the reserved width is 7 mm.

[0039] In another embodiment, the rear corner window 32 is consistent with a conventional vehicle window glass.

When the rear corner window 32 is at the lowest point of the rear corner window guide groove 31, the sealed bubble tube abuts against the outer side of the rear corner window 32. The sealed bubble tube can fill irregular gaps and has a good deformation effect, further improving the sealing effect, preventing sundries and dirt from falling on the sliding door guide rail 2, and also having a certain effect of reducing noise.

[0050] As Figure 1 and Figure 2 shown, in some alternative embodiments, it further includes two side guide grooves 34 arranged at intervals. The side guide grooves 34 are located on both sides of the rear corner window 32 along the vehicle length direction, and a driving mechanism 33 is used to drive the rear corner window 32 to move within the side guide grooves 34.

[0051] In this embodiment, the sliding door guide rail assembly further includes two side guide grooves 34 arranged at intervals. The side guide grooves 34 are located on both sides of the rear corner window 32 along the vehicle length direction, and a driving mechanism 33 is used to drive the rear corner window 32 to move within the side guide grooves 34, providing a sliding guide groove, which can ensure that the rear corner window 32 remains stable during the lifting process, avoid deviation or jamming, improve the stability of the sliding process, and the side guide grooves 34 themselves are closely attached to the rear corner window 32, which can also prevent sundries and dirt from entering, improve the sealing effect, and reduce the noise caused by the entry of air flow at the same time.

[0052] In some alternative embodiments, it further includes a corner window control unit. The corner window control unit is signal-connected to the driving mechanism 33. The corner window control unit is used to receive the sliding signal of the electric sliding door 5 and adjust the position of the rear corner window 32 according to the signal.

[0053] In this embodiment, the sliding door guide rail assembly further includes a corner window control unit. The corner window control unit is signal-connected to the driving mechanism 33. The corner window control unit is used to receive the sliding signal of the electric sliding door 5 and adjust the position of the rear corner window 32 according to the signal. When the corner window control unit receives the sliding open signal of the electric sliding door 5, the corner window control unit starts the driving mechanism 33 to drive the rear corner window 32 to move and expose the sliding door guide rail 2. When the electric sliding door 5 is in the open state and receives the sliding close command, the electric sliding door 5 performs the closing action, and the electric sliding door 5 sends a closing completion signal to the corner window control unit. The corner window control unit controls the rear corner window 32 to move to block the sliding door guide rail 2.

[0054] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, on the other hand, the present application also provides an automobile with a sliding door, which includes the above-mentioned sliding door guide rail assembly.

Since after the vehicle door is closed, the driving mechanism 33 drives the rear corner window 32 to move to cover the outside of the sliding door guide rail 2, and before the vehicle door is opened, the driving mechanism 33 drives the rear corner window 32 to move to expose the sliding door guide rail 2, the structure added outside the side body 1 is reduced, the gaps are reduced, and thus the wind noise can be effectively reduced, solving the problem in the prior art that when using a zipper structure, a retractor is needed to retract the zipper to block this sliding door groove, but there are problems with the seam matching between the rear corner window glass and the zipper and between the zipper and the side body, and it is easy to generate gaps between their mutual cooperation. The airflow may flow in during high-speed driving to generate wind noise. On the other hand, the zipper structure is relatively soft and is also prone to generate abnormal noises during driving, which affects the NVH performance of the vehicle.

[0056] In this embodiment, the rear corner window 32 is configured such that when the upper end of the rear corner window 32 is at the first design height, the rear corner window 32 blocks the sliding door guide rail 2, and when the upper end of the rear corner window 32 is at the second design height, the sliding door guide rail 2 is out of the projection range of the rear corner window 32 on the side body 1, indicating that the moving direction of the rear corner window 32 is the height direction. By adjusting the position in the height direction, the sliding door guide rail 2 can be blocked or exposed.

[0057] In this embodiment, the distance between the first design height and the second design height is less than the depth of the rear corner window guide groove 31, that is, the upper end of the rear corner window 32 is always located within the rear corner window guide groove 31. When it is necessary to block the sliding door guide rail 2, the rear corner window 32 moves downward, and when it is necessary to expose the sliding door guide rail 2, the rear corner window 32 moves upward, which not only ensures the smoothness of the process of blocking the sliding door guide rail 2 but also reduces the movement range.
