[0027] It should be understood that various modifications may be made to the embodiments disclosed herein. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the utility model will occur to those skilled in the art.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] The utility model provides a sliding door guide rail structure, including a shielding member 1, a storage portion 2, a guide rail 3 installed on a vehicle body 100, and a hinge 4 slidably installed on the guide rail 3, the storage portion is arranged corresponding to the position of the hinge 4 when the sliding door 400 is opened, the two ends of the shielding member 1 are respectively connected to the hinge 4 and the storage portion 2, the shielding member 1 is used to extend from the storage portion 2 to cover the guide rail 3 or to be retracted in the storage portion 2 to expose the guide rail 3.

[0030] Combination Figures 1 to 4 As shown, the sliding direction of the sliding door 400 is the direction shown by the X-axis in the figure, and the hinge 4 is installed on the sliding door 400. When opening the sliding door 400, the user can pull the sliding door 400 in the opposite direction of the X-axis in the figure, so that the hinge 4 slides in the opposite direction of the X-axis along the guide rail 3. The shielding member 1 should be designed accordingly according to the actual shape of the guide rail 3. For example, for the common straight-line guide rail 3, the shielding member 1 is a strip structure similar thereto, so as to play a sufficient shielding and covering role (the specific structure of the shielding member 1 is not limited, as long as it can cover the guide rail 3). In this embodiment, one end of the shielding member 1 with the strip structure moves in the opposite direction of the X-axis with the hinge 4, so that the shielding member 1 gradually shrinks; when closing the sliding door 400, the user can pull the sliding door 400 in the positive direction of the X-axis in the figure, so that the hinge 4 slides in the positive direction of the X-axis along the guide rail 3, and one end of the shielding member 1 moves in the positive direction of the X-axis with the hinge 4, so that the shielding member 1 gradually extends out from the storage portion 2.

[0031] It is understandable that the shielding member 1 should have a certain flexibility so that the shielding member 1 can be retracted into the storage portion 2 , for example, the material of a car seat belt can be referred to.

[0032] The storage portion 2 may be a storage box with a certain volume, corresponding to the position of the hinge 4 when the sliding door 400 is opened. This does not limit the storage portion 2 to be exactly the same as the position of the hinge 4, but means that the position of the storage portion 2 has a certain correspondence with the position of the hinge 4 when the sliding door 400 is opened. For example, when the sliding door 400 is opened, the hinge 4 is located at the end of the guide rail 3, and the storage portion 2 can be located at any position near the end of the guide rail 3, as long as it does not hinder the process of the shielding member 1 extending and retracting. For example, the storage box can be set along the guide rail 3. Figure 4 On the opposite end of the middle X axis (or installed at the rear of the vehicle, i.e. Figure 1 One end of the shielding member 1 is connected to the hinge 4 in the opposite direction of the X-axis, and the other end is connected to the storage box. The end of the shielding member 1 connected to the hinge 4 moves in the opposite direction of the X-axis, so that the shielding member 1 is contracted and stacked in the storage box; the end of the shielding member 1 connected to the hinge 4 moves in the positive direction of the X-axis, so that the shielding member 1 extends out of the storage box (the storage box scheme is not shown in the figure).

[0033] Preferably, combined Figure 5 As shown, the storage portion 2 includes a rotating shaft 21, and the rotating shaft 21 is rotatably mounted on the vehicle body 100. One end of the shielding member 1 is connected to the rotating shaft 21 so that the shielding member 1 is rolled up on the outer periphery of the rotating shaft 21. Figure 3 and Figure 4 As shown, one end of the shielding member 1 is connected to the hinge 4, and the other end is connected to the rotating shaft 21. When the end of the shielding member 1 connected to the hinge 4 moves in the opposite direction of the X-axis, the end of the shielding member 1 connected to the rotating shaft 21 rotates along with the rotating shaft 21, so that the shielding member 1 is gradually rolled up on the outer periphery of the rotating shaft 21, avoiding random stacking of the shielding member 1 when it is contracted, and at the same time, the space occupied by the storage portion 2 and the contracted shielding member 1 can be minimized.

[0034] More preferably, the storage portion 2 further comprises an elastic member 22 , and two ends of the elastic member 22 are respectively connected to the rotating shaft 21 and the vehicle body 100 , so as to drive the rotating shaft 21 to rotate and retract the shielding member 1 .

[0035] Combination Figures 3 to 5As shown, the elastic member 22 can be an elastic component such as a torsion spring or a coil spring, and its two ends are respectively connected to the rotating shaft 21 and the body 100. After the sliding door 400 is closed, the shielding member 1 extends out and drives the rotating shaft 21 to rotate relative to the body 100. The elastic member 22 can accumulate a certain elastic potential energy. In this way, when the sliding door 400 is opened, the end of the shielding member 1 connected to the hinge 4 moves in the opposite direction of the X-axis, and the elastic potential energy of the elastic member 22 is released, so that the end of the shielding member 1 connected to the rotating shaft 21 is retracted as the rotating shaft 21 rotates, and the elastic force of the elastic member 22 is used to keep the shielding member 1 taut, thereby avoiding the problem of stacking and jamming of the shielding member 1 with a certain flexibility, and ensuring that the movement of the shielding member 1 is relatively smooth.

[0036] Combination Figure 1 and Figure 2 As shown, when the sliding door 400 is closed, the shielding member 1 extends from the storage portion 2, and the shielding member 1 after being extended is located on the side of the guide rail 3 facing the external space, thereby forming a covering effect on the guide rail 3. It should be noted that in this embodiment, the size of the shielding member 1 can be designed as needed (for example, the width of the shielding member 1 can be close to the width of the guide rail 3), as long as it can play a certain covering effect on the guide rail 3, and its specific size is not limited.

[0037] Optionally, combined Figures 3 to 5 As shown, the storage portion 2 also includes a mounting frame 23, which is mounted on the vehicle body 100 and is rotatably connected to the rotating shaft 21. The elastic member 22 is a coil spring, and the two ends of the coil spring are respectively connected to the rotating shaft 21 and the mounting frame 23. A mounting surface is provided on the vehicle body 100, and the mounting frame 23 is arranged opposite to the mounting surface, so that the two ends of the rotating shaft 21 are respectively rotatably connected to the mounting frame 23 and the mounting surface, thereby improving the connection stability of the rotating shaft 21. The end of the coil spring close to the inner side is fixedly connected to the rotating shaft 21, and the end of the coil spring close to the outer side is fixedly connected to the mounting frame 23, so that the coil spring can be driven to contract when the rotating shaft 21 rotates. The number of coils, gaps and other parameters of the coil spring should be determined according to the limit tension of the shielding member 1 and the size of the installation space of the coil spring limited by the vehicle body 100, so as to avoid the excessive elastic force of the coil spring from damaging the shielding member 1 or causing impact force on the surrounding parts when the elastic force of the coil spring is released.

[0038] Specifically, the storage portion 2 is installed on the vehicle body 100 and is located at one end of the guide rail 3 close to the rear of the vehicle.

[0039] Combination Figure 3 and Figure 4 As shown, the storage portion 2 is installed on the vehicle body 100 at one end of the guide rail 3 close to the rear of the vehicle (i.e., the end opposite to the X-axis), and is basically at a minimum distance from the guide rail 3 to avoid occupying too much space and affecting the layout design of other vehicle structures.

[0040] Furthermore, a connecting bracket 11 is provided at one end of the shielding member 1, and a mounting portion is extended on the connecting bracket 11 toward the hinge 4, and through holes are respectively provided on the mounting portion and the hinge 4, and the mounting portion of the connecting bracket 11 is connected to the hinge 4 through a fastener 12 (such as a bolt, a pin, etc.).

[0041] The specific shape of the connecting bracket 11 can be designed according to the shape of the shielding member 1. Figure 3 As shown, a connecting bracket 11 is provided at the end of the strip-shaped shielding member 1, and the width of the connecting bracket 11 is substantially the same as that of the shielding member 1. A mounting portion is provided on the connecting bracket 11 and extends toward the hinge 4, and its structure is similar to a mounting plate structure with a mounting hole. Another mounting hole is provided on the end of the hinge 4 close to the rear of the vehicle (i.e., the end facing the opposite direction of the X-axis), so that the mounting portion can be connected to the hinge 4 by a fastener 12, and the hinge 4 drives the shielding member 1 to extend from or retract to the storage portion 2 through the connecting bracket 11. The connecting bracket 11 generally has higher rigidity than the shielding member 1, so that the connecting bracket 11 plays a role in maintaining the flatness of the outer shape of the end of the shielding member 1, and the connection stability between the shielding member 1 and the hinge 4 can be improved by the connecting bracket 11.

[0042] Combination Figure 1 and Figure 2 As shown, the vehicle body 100 is provided with a side window 200 and a decorative strip 300 corresponding to the edge of the side window 200. There is a certain gap between the edge of the side window 200 in the opposite direction of the Z axis in the figure and the edge of the decorative strip 300 in the positive direction of the Z axis in the figure. The shielding member 1 is used to cover the guide rail 3 between the side window 200 and the decorative strip 300. In the conventional vehicle model, the shielding member 1 is not provided at the gap between the side window 200 and the decorative strip 300, resulting in the guide rail 3 being exposed on one side in the positive direction of the Y axis in the figure. The shielding member 1 in this embodiment fills the gap between the side window 200 and the decorative strip 300, forming a covering effect on the guide rail 3. In order to ensure the covering effect of the shielding member 1 on the guide rail 3, one side edge of the shielding member 1 is located within the edge of the side window 200 facing the decorative strip 300, and preferably has a certain gap with the side edge of the side window 200, so as to ensure that the friction force on the shielding member 1 is minimized and the shielding member 1 is prevented from being worn.

[0043] In addition, in traditional vehicles without a shielding member 1, in order to ensure the appearance quality, the guide rail 3 and the side window 200 need to maintain the same color. In order to ensure the sliding performance of the guide rail 3, a more complex and high-cost process is required to change the color of the guide rail 3. The shielding member 1 in this embodiment replaces the guide rail 3 and becomes a part of the vehicle appearance. Compared with the guide rail 3, there is no need to consider the sliding performance of the guide rail 3 when changing the color of the shielding member 1. The process of maintaining the same color between the shielding member 1 and the side window 200 is relatively simple (usually the side window 200 and the shielding member 1 are both black), which not only reduces costs but also ensures the high quality of the vehicle appearance.

[0044] Furthermore, combined with Figure 1 and Figure 2 As shown, the edge of the decorative strip 300 (the edge along the positive side of the Z axis in the figure) and the edge of the guide rail 3 (the edge along the negative side of the Z axis in the figure) are spaced apart to form a slide groove 5. Optionally, part of the structure of the vehicle body 100 can extend to the bottom of the slide groove 5 to form a slide groove 5 with a U-shaped cross-section together with the decorative strip 300 and the guide rail 3, and the edge of the shielding member 1 (the edge along the Z axis direction in the figure) is slidably connected in the slide groove 5.

[0045] In this way, the slide groove formed by the decorative strip 300 and the guide rail 3 can guide the sliding process of the shielding member 1, ensure that the sliding process of the shielding member 1 is relatively smooth, and ensure that the surface of the shielding member 1 is flat. By designing the gap between the shielding member 1 and the decorative strip 300 and the guide rail 3, the friction force of the shielding member 1 during the extension and contraction process can be minimized to avoid wear of the shielding member 1.

[0046] Combination Figure 2 As shown, the guide rail 3 is concave to form a guide groove 31, and then combined with Figure 6 As shown, the hinge 4 is provided with a pulley block 41, and the hinge 4 is slidably installed in the guide groove 31 through the pulley block 41. The concave guide rail 3 is easier to be covered than the convex guide rail 3, which is conducive to covering and protecting by the shielding member 1. The pulley block 41 installed on the hinge 4 may include a plurality of pulleys arranged in different directions, for example Figure 6 In the figure, the hub surface of one group of pulleys is arranged perpendicular to the horizontal plane to bear the vertical gravity, and the hub surface of the other group of pulleys is arranged parallel to the horizontal plane to bear the deflection force. In this way, the pulley group 41 can ensure the sliding performance of the sliding door 400 along the guide rail 3 and avoid the sliding door 400 from deflecting during the sliding process.

[0047] The sliding door guide rail structure of the utility model connects one end of the shielding member 1 to the hinge 4 and the other end to the storage portion 2. When the sliding door 400 is opened, the hinge 4 can drive the shielding member 1 to slide, so that the shielding member 1 is retracted in the storage portion 2, thereby exposing the guide rail 3, so that the sliding door 400 can be smoothly opened along the guide rail 3; when the sliding door 400 is closed, the hinge 4 drives the shielding member 1 to slide in the opposite direction, so that the shielding member 1 extends from the storage portion 2, thereby covering the guide rail 3, preventing dust, sand and gravel from adhering to the guide rail 3 and aggravating wear, playing a certain protective role for the guide rail 3, and improving the service life of the sliding door guide rail structure; at the same time, after the sliding door 400 is closed, the shielding member 1 covers the guide rail 3, preventing the guide rail 3 with a concave-convex structure from being exposed, which is beneficial to improving the aerodynamic performance of the whole vehicle; in addition, the shielding member 1 replaces the guide rail 3 to become a vehicle appearance component. When changing the color, for example, compared with the guide rail 3, the appearance process of the shielding member 1 is relatively simple and the cost is relatively low.

[0048] The utility model also provides a vehicle, comprising the sliding door guide rail structure.

[0049] The vehicle of the present invention adopts a sliding door guide rail structure on the side of the vehicle, for example, to realize the opening and closing of the sliding door 400, wherein one end of the shielding member 1 is connected to the hinge 4, and the other end is connected to the storage portion 2. When the sliding door 400 is opened, the hinge 4 can drive the shielding member 1 to slide, so that the shielding member 1 is retracted in the storage portion 2, thereby exposing the guide rail 3, so that the sliding door 400 can be smoothly opened along the guide rail 3; when the sliding door 400 is closed, the hinge 4 drives the shielding member 1 to slide in the opposite direction, so that the shielding member 1 extends out from the storage portion 2, Thereby, it serves to cover the guide rail 3, preventing dust, sand and gravel from adhering to the guide rail 3 and aggravating wear, and plays a certain protective role for the guide rail 3, thereby increasing the service life of the sliding door guide rail structure; at the same time, after the sliding door 400 is closed, the shielding member 1 covers the guide rail 3 to prevent the guide rail 3 with a concave-convex structure from being exposed, which is beneficial to improving the aerodynamic performance of the entire vehicle; in addition, the shielding member 1 replaces the guide rail 3 to become a vehicle appearance component. When changing the color, for example, compared with the guide rail 3, the appearance process of the shielding member 1 is relatively simple and the cost is relatively low.
