[0052] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0055] In the vehicle manufacturing industry, sliding doors are widely used in various vehicle types, including MPVs, SUVs, and passenger / cargo vans, due to their advantages such as saving lateral space and improving passenger accessibility. Hinges are the core transmission and support components connecting the vehicle body and the sliding door. However, current vehicle sliding door hinges still have shortcomings in terms of stability and reliability, making it difficult to meet the vehicle's requirements for stable operation of the sliding door system.

[0056] Based on the above-mentioned technical problems, this application proposes a hinge module. However, it should be noted that the hinge module of this application can be applied not only to the sliding doors of vehicles, but also to other structural components that need to slide. The following examples are for the purpose of describing the various embodiments of this application, taking the application of the hinge module to the sliding door of a vehicle as an example, but they should not be regarded as a limitation of this application, and the following content will not elaborate on this.

[0057] like Figures 1-6As shown, the hinge module according to an embodiment of this application includes a first mounting base 11, a first slider 12, and a connecting arm 13. The first slider 12 includes a first sliding bracket 121, a first limiting wheel 122, and a first load-bearing wheel 123. The first limiting wheel 122 and the first load-bearing wheel 123 are rotatably mounted on the first sliding bracket 121. The rotation axis of the first limiting wheel 122 is arranged at an angle to the rotation axis of the first load-bearing wheel 123, so that the first slider 12 restricts the walking direction of the first load-bearing wheel 123 through the first limiting wheel 122. The two ends of the connecting arm 13 are rotatably connected to the first sliding bracket 121 and the first mounting base 11, respectively. A guide wheel 133 is provided on the connecting arm 13, and the guide wheel 133 is used to guide the rotation direction of the connecting arm 13.

[0058] In other words, the first mounting seat 11 can be installed on the structural component to be slidable, such as the sliding door 200 of the vehicle 1000. After the first mounting seat 11 is installed on the sliding door 200, the first load-bearing wheel 123 can slide on the bearing surface constructed by the body 100 of the vehicle 100. By sliding or rolling the first load-bearing wheel 123, the sliding door 200 can slide relative to the body 100, thereby enabling the sliding door 200 to open or close.

[0059] During the sliding or rolling of the first load-bearing wheel 123, the first limiting wheel 122 can limit the position of the first load-bearing wheel 123 in its axial direction. For example, the rotation axis of the first load-bearing wheel 123 can be the left-right direction of the vehicle 1000, and the rotation axis of the first limiting wheel 122 can be the up-down direction of the vehicle 1000. The first limiting wheel 122 can cooperate with the limiting surface constructed by the vehicle body 100 to limit the position of the first load-bearing wheel 123 in the left-right direction, thereby limiting the position of the sliding door 200 in the left-right direction. As a result, when the sliding door 200 slides in the front-back direction to open or close, the relative position of the sliding door 200 is limited, so that the sliding door 200 can open or close more stably.

[0060] Furthermore, in the example of this application, the rotation axis of the first limiting wheel 122 is arranged at an angle to the rotation axis of the first load-bearing wheel 123. Taking the rotation axis of the first load-bearing wheel 123 as an example where it is in the left-right direction of the vehicle 1000, the rotation axis of the first limiting wheel 122 does not have to be in the up-down direction. That is, the rotation axis of the first load-bearing wheel 123 and the rotation axis of the first limiting wheel 122 are not perpendicular to each other, as long as the first limiting wheel 122 can perform the function of limiting the axial position of the first load-bearing wheel 123. The position of the rotation axis of the first limiting wheel 122 does not need to be restricted. Similarly, as long as the first load-bearing wheel 123 can support the sliding door 200 and drive the sliding door 200 to slide, the rotation axis of the first load-bearing wheel 123 can also be made not to extend in the left and right direction. For example, the rotation axis of the first load-bearing wheel 123 has an angle with the straight line in the left and right direction. The angle can be an acute angle. Therefore, the rotation axis of the first load-bearing wheel 123 and the rotation axis of the first limiting wheel 122 do not need to be restricted.

[0061] Furthermore, when the sliding door 200 moves from the closed position to the open position, the sliding door 200 needs to move outward relative to the vehicle body 100. This outward movement refers to moving a certain distance away from the vehicle body 100. Specifically, the vehicle body 100 has a doorway. When the sliding door 200 is inside the doorway, the outer surface of the vehicle body 100 near the doorway can be coplanar with the outer surface of the sliding door 200. When the sliding door 200 opens, it can first move outward a certain distance and then slide along the outer surface of the vehicle body 100, thereby opening the doorway. This outward movement of the sliding door 200 when opening can be achieved through the connecting arm 13 in this embodiment. Specifically, both ends of the connecting arm 13 are rotatably connected to the first sliding bracket 121 and the first mounting base 11, respectively. Therefore, when the connecting arm 13 rotates relative to the first sliding bracket 121, in the left-right direction of the vehicle 1000, the first... The mounting base 11 moves away from the first sliding bracket 121. To ensure the sliding door 200's posture when open, the end of the connecting arm 13 can be rotatably connected to the first mounting base 11. The connecting arm 13 is provided with a guide wheel 133, which guides the rotation direction of the connecting arm 13. The length and rotation angle of the connecting arm 13 can control the distance of the sliding door 200 from the vehicle body 100. By controlling the distance of the sliding door 200 from the vehicle body 100, the posture of the sliding door 200 when open can be adjusted, which can also better restrict the sliding door 200, so that the sliding door 200 can be opened relatively stably. Similarly, during the closing process of the sliding door 200, the cooperation of the first mounting base 11, the first slider 12, and the connecting arm 13 can also make the sliding door 200 close relatively stably, with high reliability and good stability.

[0062] Therefore, as can be seen from the above, the hinge module disclosed in the above embodiments of this application, through the cooperation of the first sliding bracket 121, the first limiting wheel 122 and the first load-bearing wheel 123, can not only better support the sliding door 200, but also limit the relative position of the sliding door 200 by limiting the relative position of the first load-bearing wheel 123, so that the sliding door 200 can be opened or closed more stably. Furthermore, the two ends of the connecting arm 13 are rotatably connected to the first sliding bracket 121 and the first mounting base 11 respectively. The connecting arm 13 is provided with a guide wheel 133, which is used to guide the rotation direction of the connecting arm 13. This can better control the distance between the sliding door 200 and the vehicle body 100 when it is open, as well as control the posture of the sliding door 200, thereby further improving the stability of the sliding door 200. Thus, the hinge module of this application has high reliability and stability. When the structural components are configured with the hinge module of this application, they can have high reliability and stability.

[0063] Furthermore, by enabling the connecting arm 13 to rotate, this application effectively reduces the space occupied by the hinge module in the left-right direction when the sliding door 200 is closed. This results in a more compact overall structure of the hinge module, which is beneficial for its placement in devices such as the vehicle 1000. For example, when the hinge module of this embodiment is placed on the vehicle 1000, the rotation of the connecting arm 13 reduces the overall size of the hinge module in the left-right direction, preventing it from excessively occupying the battery pack's installation space. This, in turn, helps to increase the energy density of the battery pack and thus increases the driving range of the vehicle 1000.

[0064] Therefore, according to the hinge module of this application embodiment, the hinge module cooperates with the first sliding bracket 121, the first limiting wheel 122 and the first load-bearing wheel 123, and is connected to the connecting arm 13, with both ends of the connecting arm 13 respectively rotatably connected to the first sliding bracket 121 and the first mounting base 11. The connecting arm 13 is provided with a guide wheel 133, which is used to guide the rotation direction of the connecting arm 13. This makes the hinge module of this application have high reliability and stability. When the structural component is configured with the hinge module of this application, it can have high reliability and stability.

[0065] In some embodiments of this application, such as Figure 5 and Figure 6As shown, the first sliding bracket 121 includes a first mounting plate 1211 and a second mounting plate 1212. The first mounting plate 1211 and the second mounting plate 1212 are arranged at intervals along the axial direction of the first limiting wheel 122. The first slider 12 also includes a second limiting wheel 124. The first limiting wheel 122 is rotatably mounted on the first mounting plate 1211, and the second limiting wheel 124 is rotatably mounted on the second mounting plate 1212.

[0066] In other words, the hinge module can use the first limiting wheel 122 and the second limiting wheel 124, which are set at intervals, to jointly limit the first load-bearing wheel 123. By adding the second limiting wheel 124, the limiting effect on the first load-bearing wheel 123 can be improved, which can further improve the stability of the first load-bearing wheel 123, thereby improving the stability of the sliding door 200 when sliding.

[0067] In addition, the first limiting wheel 122 and the second limiting wheel 124 are respectively mounted on different mounting plates (i.e., the first mounting plate 1211 and the second mounting plate 1212). The first limiting wheel 122 and the second limiting wheel 124 are less likely to interfere with each other, and it is easier to make the first limiting wheel 122 and the second limiting wheel 124 have sufficient installation space, which helps to reduce the assembly difficulty of the first limiting wheel 122 and the second limiting wheel 124 and improve the assembly efficiency of the first limiting wheel 122 and the second limiting wheel 124.

[0068] For example, since the first limiting wheel 122 and the second limiting wheel 124 are respectively mounted on the spaced-apart first mounting plate 1211 and second mounting plate 1212, the first limiting wheel 122 and the second limiting wheel 124 can be limited by different limiting surfaces. In this way, the diameters of the first limiting wheel 122 and the second limiting wheel 124 can be the same or different according to actual needs, thereby improving the flexibility of the arrangement of the first limiting wheel 122 and the second limiting wheel 124.

[0069] In the above-mentioned technical method, by setting the first mounting plate 1211 and the second mounting plate 1212, and the first limiting wheel 122 and the second limiting wheel 124 respectively mounted on the spaced-apart first mounting plate 1211 and the second mounting plate 1212, the limiting effect on the first load-bearing wheel 123 can be improved, the stability of the first load-bearing wheel 123 can be further improved, and thus the stability of the sliding door 200 during sliding can be improved. In addition, it is easier to make the first limiting wheel 122 and the second limiting wheel 124 have sufficient installation space, which helps to reduce the assembly difficulty of the first limiting wheel 122 and the second limiting wheel 124 and improve the assembly efficiency of the first limiting wheel 122 and the second limiting wheel 124.

[0070] It should be noted that the axial direction of the first limiting wheel 122 is the same as the direction of the rotation axis of the first limiting wheel 122.

[0071] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the first limiting wheel 122 is axial in the up-down direction, the first mounting plate 1211 is located below the second mounting plate 1212, and the first load-bearing wheel 123 is mounted on the first mounting plate 1211.

[0072] In other words, both the first load-bearing wheel 123 and the first limiting wheel 122 are mounted on the first mounting plate 1211. This allows the first limiting wheel 122 to effectively limit the first load-bearing wheel 123. Furthermore, compared to the second limiting wheel 124, the first limiting wheel 122 plays a primary role in limiting the first load-bearing wheel 123. Therefore, the diameter and material of the first limiting wheel 122 can be individually controlled to improve its structural strength, thereby reliably limiting the first load-bearing wheel 123. The second limiting wheel 124 is located on... Above the first load-bearing wheel 123, it can serve as an auxiliary limit for the first load-bearing wheel 123. Therefore, the diameter and material of the second limit wheel 124 can be controlled separately according to actual needs, so that the structural strength of the second limit wheel 124 is slightly worse than that of the first limit wheel 122. This application does not impose any restrictions on this. In addition, it can be understood that the first limit wheel 122 and the second limit wheel 124 can also have completely identical structural features, that is, the first limit wheel 122 and the second limit wheel 124 are completely identical in diameter and material. This application does not impose any restrictions on this.

[0073] Furthermore, the first load-bearing wheel 123 and the first limiting wheel 122 are both mounted on the first mounting plate 1211, and the second limiting wheel 124 is mounted on the second mounting plate 1212. The structure is relatively compact, which can effectively reduce the size of the first slider 12 in the vertical direction, which is beneficial to the miniaturization design of the hinge module.

[0074] In the above-mentioned technical method, by arranging the first limiting wheel 122 and the first load-bearing wheel 123, the limiting effect of the first limiting wheel 122 and the second limiting wheel 124 on the first load-bearing wheel 123 can be improved. Furthermore, directly mounting the first load-bearing wheel 123 on the first mounting plate 1211 is beneficial to improving the compactness of the first slider 12, thereby facilitating the miniaturization design of the hinge module.

[0075] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, at least two first limiting wheels 122 are provided, and the first load-bearing wheel 123 is rotatably installed between two adjacent first limiting wheels 122.

[0076] In other words, the first limiting wheel 122 plays a major role in limiting the first load-bearing wheel 123. Therefore, by increasing the number of first limiting wheels 122 and arranging the first load-bearing wheel 123 between two adjacent first limiting wheels 122, the limiting effect on the first load-bearing wheel 123 can be improved, making the first load-bearing wheel 123 move more stably, which in turn helps the sliding door 200 to be opened or closed more stably.

[0077] For example, there may be two or more first limiting wheels 122, and this application does not limit this. In addition, the number of first load-bearing wheels 123 may also be two or more according to actual needs, and this application does not limit this either.

[0078] In the above-mentioned technical method, by setting the number of the first limiting wheels 122 and arranging the position of the first load-bearing wheels 123, the limiting effect of the first load-bearing wheels 123 can be improved, so that the first load-bearing wheels 123 can move more stably, which in turn helps the sliding door 200 to be opened or closed more stably.

[0079] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the second limiting wheel 124 and the connecting arm 13 are rotatably mounted on opposite sides of the second mounting plate 1212, and the rotation axis of the connecting arm 13 at the rotatable connection with the second mounting plate 1212 is collinear with the rotation axis of the second limiting wheel 124.

[0080] In other words, the second limiting wheel 124 and the connecting arm 13 are rotatably mounted on opposite sides of the second mounting plate 1212, which can better utilize the space on both sides of the second mounting plate 1212, which is conducive to the integrated and miniaturized design of the first slider 12, and thus conducive to the miniaturized design of the hinge module.

[0081] Furthermore, by making the rotation axis of the connecting arm 13 at the rotatable connection point with the second mounting plate 1212 collinear with the rotation axis of the second limiting wheel 124, the stability of the connecting arm 13 and the second limiting wheel 124 during limiting can be improved. If the rotation axis of the connecting arm 13 at the rotatable connection point with the second mounting plate 1212 is not collinear with the rotation axis of the second limiting wheel 124, there will be two different rotation axes on the same second mounting plate 1212, which will easily result in two points with different forces on the second mounting plate 1212, thus making the second mounting plate 1212 unstable, and consequently making both the connecting arm 13 and the second limiting wheel 124 unstable during rotation.

[0082] In the above-mentioned technical approach, the arrangement of the installation positions of the second limiting wheel 124 and the connecting arm 13 can facilitate the integrated and miniaturized design of the first slider 12, thereby facilitating the miniaturized design of the hinge module. In addition, by designing the rotation axis of the connecting arm 13 and the rotation axis of the second limiting wheel 124 to be collinear, the stability of the connecting arm 13 and the second limiting wheel 124 can be improved, thereby enhancing the stability of the hinge module and, consequently, the stability of the sliding door 200.

[0083] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the two ends of the connecting arm 13 have a first bushing 131 and a second bushing 132 respectively. The hinge module also includes a first pin and a second pin. The first pin passes through the first bushing 131 to rotatably connect one end of the connecting arm 13 to the first sliding bracket 121, and the second pin passes through the second bushing 132 to rotatably connect the other end of the connecting arm 13 to the first mounting base 11.

[0084] In other words, the cooperation between the first bushing 131 and the first pin, and the cooperation between the second bushing 132 and the second pin, can better realize the rotational connection between the connecting arm 13 and the first sliding bracket 121 and the first mounting seat 11. This can better improve the anti-deformation ability between the connecting arm 13 and the first sliding bracket 121, and between the connecting arm 13 and the first mounting seat 11. As a result, the connecting arm 13 and the first sliding bracket 121, and between the connecting arm 13 and the first mounting seat 11, are less likely to wobble or deviate during rotation, thus improving the rotational stability between the connecting arm 13 and the first sliding bracket 121, and between the connecting arm 13 and the first mounting seat 11.

[0085] In addition, the split design of the first bushing 131 and the second bushing 132, together with the independent first pin and second pin, can ensure that the rotation of the two ends of the connecting arm 13 does not interfere with each other, which can improve the flexibility of mechanical movement and facilitate smoother angle adjustment of the connecting arm 13.

[0086] Furthermore, this assembly structure simplifies the installation process. The plug-in and pull-out engagement of the pins and bushings (the fit between the first bushing 131 and the first pin, and the fit between the second bushing 132 and the second pin) reduces assembly difficulty and facilitates later maintenance and component replacement. Simultaneously, the rigid contact between the bushings and pins (the fit between the first bushing 131 and the first pin, and the fit between the second bushing 132 and the second pin) reduces stress concentration, extends the service life of components by distributing loads, and provides reliable support for the long-term stable operation of the equipment.

[0087] In the above-mentioned technical method, the cooperation between the first bushing 131 and the first pin, and the cooperation between the second bushing 132 and the second pin, can effectively improve the rotational stability between the connecting arm 13 and the first sliding bracket 121, and between the connecting arm 13 and the first mounting base 11. It also has good flexibility, which is conducive to the smooth angle adjustment of the connecting arm 13. Furthermore, the plug-in cooperation between the pin and the bushing (the cooperation between the first bushing 131 and the first pin, and the cooperation between the second bushing 132 and the second pin) can reduce the assembly difficulty and reduce stress concentration, thereby improving the service life.

[0088] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the first sliding bracket 121 includes a first mounting plate 1211, a second mounting plate 1212, and a connecting plate 1213. The connecting plate 1213 is connected between the first mounting plate 1211 and the second mounting plate 1212 and forms a first mounting groove with the first mounting plate 1211 and the second mounting plate 1212. One end of the connecting arm 13 is rotatably installed in the first mounting groove. And / or, the first mounting base 11 includes a base plate 111 and a folding plate 112. The folding plate 112 is connected to the base plate 111 and forms a second mounting groove with the base plate 111. The other end of the connecting arm 13 is rotatably installed in the second mounting groove.

[0089] In the above-mentioned technical method, the first assembly groove connects the first and second mounting plates 1212 through the connecting plate 1213 to form a relatively stable frame, which can provide better limiting for the end of the connecting arm 13 and can better improve the structural stability of the transmission process. Similarly, the second assembly groove can also provide better limiting for the end of the connecting arm 13 and can better improve the structural stability of the transmission process.

[0090] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the rotation axes at both ends of the connecting arm 13 are parallel to the rotation axis of the guide wheel 133, and the shape formed by the lines connecting the rotation axes at both ends of the connecting arm 13 and the rotation axis of the guide wheel 133 in the projection plane perpendicular to the rotation axis of the guide wheel 133 is a triangle.

[0091] In other words, the parallel rotation axis design ensures that the movement directions of the connecting arm 13 and the guide wheel 133 are more aligned, reducing the additional torque caused by the intersecting rotation axes. This reduces energy loss during mechanical operation and makes the rotation of the connecting arm 13 more stable. Secondly, the triangular rotation axis layout within the projection plane utilizes the geometric stability of triangles to form a rigid support system between the connecting arm 13 and the guide wheel 133. This structure effectively distributes external loads, maintaining balanced force transmission even under complex working conditions, significantly reducing the risk of component deformation due to excessive stress at a single point, and extending the equipment's service life. Furthermore, the triangular layout provides a more reasonable range of motion angles for the connecting arm 13, which, combined with the parallel axis design, also helps improve the guiding accuracy of the guide wheel 133.

[0092] In the above-mentioned technical approach, the parallel rotation axis design can reduce the additional torque caused by the intersection of rotation axes, thereby reducing energy loss during mechanical operation and making the rotation of the connecting arm 13 more stable. The triangular layout of the rotation axis can better distribute external loads, which is beneficial to improving the structural stability of the connecting arm 13 and also to improving the guiding accuracy of the guide wheel 133.

[0093] In some embodiments of this application, such as Figures 7-9 , Figure 18 As shown, the first slider 12 also includes a balance wheel 125, which is rotatably mounted on the first sliding bracket 121 and spaced apart from the first load-bearing wheel 123 along the walking direction of the first load-bearing wheel 123. The rotation axis of the balance wheel 125 is parallel to the rotation axis of the first load-bearing wheel 123.

[0094] For example, the first load-bearing wheel 123 travels in the front-to-back direction, and the first sliding bracket 121 extends in the front-to-back direction. When the hinge module 1 is arranged between the vehicle body 100 and the sliding door 200, as the sliding door 200 slides, the center of gravity of the sliding door 200 changes continuously relative to the hinge module 1. When the sliding door 200 deflects along the first load-bearing wheel 123 due to the change in the center of gravity, the balance wheel 125 can abut against the track surface arranged on the vehicle body 100, thereby enabling the sliding door 200 to slide relatively stably.

[0095] For example, there may be one or more balance wheels 125. Balance wheels 125 may be provided on both the front and rear sides of the first load-bearing wheel 123. This application does not impose any restrictions.

[0096] More specifically, as described below, in the second groove 212, the balance wheel 125 can roll on the downward-facing groove surface of the second groove 212.

[0097] In addition, it needs to be further explained that when the center of gravity of the sliding door 200 changes, but the stability of the sliding door 200 is not affected, the balance wheel 125 is only located in the second slide groove 212 and does not need to roll against the groove surface of the second slide groove 212. When the sliding door 200 deflects due to the change in the center of gravity, the balance wheel 125 limits the sliding door 200 to slide stably by being limited by the second slide groove 212.

[0098] In the above-mentioned technical method, by setting the balance wheel 125, the sliding door 200 is less likely to be affected by the instability of the center of gravity, which can help the sliding door 200 slide stably.

[0099] This application also proposes a sliding assembly 10 having the hinge module described in the above embodiments.

[0100] like Figures 5-13 As shown, the sliding assembly 10 according to the embodiment of this application includes a hinge module and a slide rail assembly 2. The slide rail assembly 2 includes a first slide rail 21 and a second slide rail 22. The first limiting wheel 122 and the first load-bearing wheel 123 can be slidably engaged with the first slide rail 21, and the guide wheel 133 is engaged with the second slide rail 22.

[0101] In other words, the first slide rail 21 has a bearing surface, and the first load-bearing wheel 123 can slide on the first slide rail 21, thereby driving the sliding door 200 to slide. The first limiting wheel 122 can effectively limit the position of the first load-bearing wheel 123 by cooperating with the first slide rail 21, thereby making the first load-bearing wheel 123 slide stably along the first slide rail 21. Furthermore, since both the first limiting wheel 122 and the first load-bearing wheel 123 are cooperating on the first slide rail 21, the axial load of the first load-bearing wheel 123 can be effectively transmitted to the first limiting wheel 122. Thus, through the limiting between the first limiting wheel 122 and the first slide rail 21, the limiting of the first load-bearing wheel 123 can be effectively improved, resulting in high reliability and good stability.

[0102] The connecting arm 13 can rotate well through the cooperation of the guide wheel 133 and the second slide rail 22, so that the sliding door 200 can slide to the outside of the vehicle body 100 and then slide along the vehicle body 100 to open the sliding door 200.

[0103] In this example, the first slide rail 21 and the second slide rail 22 are independent of each other and work together to guide the first limit wheel 122 and the guide wheel 133 respectively. They can also form a double constraint on the first slider 12 to a certain extent, thereby reducing the risk of the first slider 12 shaking during movement, making the hinge module operate more stably, and thus making the sliding door 200 open or close more stably.

[0104] According to the sliding assembly 10 of this application embodiment, by setting the first slide rail 21, the second slide rail 22 and the hinge module 1 of the above embodiment, the hinge module 1 can cooperate well with the two independent first slide rails 21 and second slide rails 22. In this way, while guiding the first limiting wheel 122 and the guide wheel 133 respectively, it can also form a double constraint on the first slider 12 to a certain extent. This can better reduce the risk of the first slider 12 shaking during movement, so that the hinge module can operate more stably, and thus the sliding door 200 can be opened or closed more stably.

[0105] In some embodiments of this application, such as Figure 8 and Figure 9 As shown, the first slide rail 21 has a first slide groove 211 and a second slide groove 212 with opposite openings. The first slider 12 also includes a second limiting wheel 124. The first limiting wheel 122 and the first load-bearing wheel 123 are both adapted to the first slide groove 211, and the second limiting wheel 124 is adapted to the second slide groove 212.

[0106] In the above-mentioned technical method, the first load-bearing wheel 123 plays a role in bearing the load of the sliding door 200, and the first limiting wheel 122 plays a role in limiting the first load-bearing wheel 123. By adapting both the first load-bearing wheel 123 and the first limiting wheel 122 into the first slide groove 211, the first load-bearing wheel 123 can be effectively limited, which is conducive to the stable movement of the first load-bearing wheel 123. Furthermore, by adapting the second limiting wheel 124 into the second slide groove 212, the axial load of the first load-bearing wheel 123 can be effectively offset, which can effectively improve the stability of the first load-bearing wheel 123.

[0107] For example, the rotation axis of the first limiting wheel 122 and the rotation axis of the second limiting wheel 124 are parallel but not collinear. Furthermore, the two side walls of the first slide groove 211 and the two side walls of the second slide groove 212 are also not coplanar. Thus, when the first limiting wheel 122 slides in the first slide groove 211 and the second limiting wheel 124 slides in the second slide groove 212, the first limiting wheel 122 and the second limiting wheel 124 slide along two non-coplanar sliding planes, respectively. Thus, by cooperating with the first limiting wheel 122 and the second limiting wheel 124, the swaying of the sliding door 200 can be reduced in the direction perpendicular to the rotation axis of the first limiting wheel 122 or the rotation axis of the second limiting wheel 124, thereby improving the stability of the sliding door 200 during sliding.

[0108] In some embodiments of this application, such as Figure 8 and Figure 9 , Figure 12 and Figure 13As shown, one end of the second slide rail 22 is connected to one end of the first slide rail 21, and the other end of the second slide rail 22 is bent away from the first slide rail 21 to form an arc-shaped rail. The second slide rail 22 has a third groove 220 and a first slot 2201 located at the other end of the second slide rail 22. The second groove 212 has a second slot 2111. At least two guide wheels 133 are provided, including a first guide wheel 1331 and a second guide wheel 1332. The first guide wheel 1331 and the second guide wheel 1332 are spaced apart along the rotation direction of the connecting arm 13. The first guide wheel 1331 is located on the side of the second guide wheel 1332 that is close to the first slot 2201. The positional relationship between the first slot 2201, the second slot 2111, the first guide wheel 1331 and the second guide wheel 1332 is configured such that when the second guide wheel 1332 slides out of the first slot 2201, the first guide wheel 1331 passes through the second slot 2111 and enters the second slide groove 212.

[0109] For example, the sliding door 200 can open from front to back. The first slide rail 21 extends in the front-back direction, and the second slide rail 22 is located at the front end of the first slide rail 21. That is, the front end of the first slide rail 21 can be connected to the front end of the second slide rail 22. The second slide rail 22 extends along an arc in the front-back direction. After the guide wheel 133 is arranged in the third slide groove 220, as the connecting arm 13 rotates, the guide wheel 133 can slide out from the first slot 2201 at the rear end of the third slide groove 220. Since there are multiple guide wheels 133, when the first guide wheel 133 is rotated, the guide wheel 133 can slide out from the first slot 2201 at the rear end of the third slide groove 220. After the first guide wheel 133 slides out of the third groove 220, the remaining guide wheels 133 are still inside the third groove 220. Therefore, through the cooperation of the remaining guide wheels 133 and the third groove 220, the connecting arm 13 can continue to rotate. Specifically, as in the example above, after the first guide wheel 1331 slides out of the third groove 220, the second guide wheel 1332 still guides the connecting arm 13 to rotate inside the third groove 220. During the rotation of the connecting arm 13, the first guide wheel 1331 can rotate with the connecting arm 13, thereby allowing it to enter the third groove 2111 from the second slot. A slide rail 21, as shown in the figure, has a first slide groove 211 and a second slide groove 212. The first slide groove 211 and the second slide groove 212 face each other downwards. In the example shown, the second slide groove 212, located above, is at the same horizontal level as the third slide groove 220. The second slide groove 212 has a second opening 2111. When the first guide wheel 1331 rotates with the connecting arm 13, it can enter the second slide groove 212 from the second opening 2111. At this time, the connecting arm 13 cannot continue to rotate, but the connecting arm 13 can pass through the first guide wheel. The first guide wheel 1331 and the second slide rail 212 slide along the second slide rail 212. At this time, the first guide wheel 1331 and the second limit wheel 124 slide along the second slide rail 212, and the first limit wheel 122 and the first load-bearing wheel 123 slide along the first slide rail 211. This allows the sliding door 200 to slide well in the front and back directions. At this time, the first guide wheel 1331 also plays a role in limiting the first load-bearing wheel 123, making the movement of the first load-bearing wheel 123 more stable. As a result, the sliding door 200 can be opened or closed more stably.

[0110] Regarding the arrangement of multiple guide wheels 133, it is understandable that if there is only one guide wheel 133, when it slides out of the first slot 2201, it loses its constraint on the connecting arm 13, which can easily lead to unstable rotation of the connecting arm 13. However, by providing at least two guide wheels 133, such as the first guide wheel 1331 and the second guide wheel 1332, when the first guide wheel 1331 slides out of the first slot 2201, the second guide wheel 1332 continues to slide within the third slide groove 220. This effectively guides the movement direction of the connecting arm 13 and the first guide wheel 1331, causing the first guide wheel 1331 to move towards the second slot 2111. When the second guide wheel 1332 slides out of the first slot 2201, the first guide wheel 1331 passes through the second slot 2111 and enters the first slide rail 21, thereby constraining the movement trajectory of the connecting arm 13 through its cooperation with the first slide rail 21.

[0111] In the example above, the second slide 212 and the third slide 220 located at the top are at the same horizontal level. It can be understood that the first slide 211 located at the bottom can also be at the same horizontal level as the third slide 220. This application does not impose any restrictions, but the specific details are not elaborated here.

[0112] For example, the central angle of the curved track can be 90°, or it can be an acute angle or an obtuse angle, and this application does not limit it in this regard.

[0113] For example, the sliding component 10 of this application can be applied between the body 100 and the sliding door 200 of the vehicle 1000. In this application, through the cooperation of the arc-shaped rail and the connecting arm 13, the sliding door 200 can be moved away from the body 100 and can also slide along the body 100. This can reduce the structural complexity of the sliding component 10, thereby reducing the volume of the sliding component 10. Furthermore, the connecting arm 13 cooperates with the arc-shaped rail through the guide wheel 133, so that the connecting arm 13 and the arc-shaped rail can partially overlap in the vertical direction when stored. This can reduce the size of the sliding component 10 in the left and right directions of the vehicle 1000, thereby improving the layout of the vehicle 1000.

[0114] In the above-mentioned technical method, by arranging the first slide rail 21, the second slide rail 22 and the guide wheel 133, the sliding component 10 can be better limited during the overall movement, and the stability is good. Furthermore, by cooperating with the arc-shaped rail and the connecting arm 13, the size of the sliding component 10 in the left and right directions of the vehicle 1000 can be reduced, which is beneficial to the layout of the vehicle 1000.

[0115] In some embodiments of this application, such as Figures 8-11As shown, the first slide rail 21 is a straight rail extending along a straight line; the second slide rail 22 includes a guide rail section 222 and an arc-shaped section 221. The guide rail section 222 is spaced apart from the first slide rail 21. One end of the arc-shaped section 221 is connected to the end of the guide rail section 222, and the other end is bent toward the first slide rail 21.

[0116] In other words, this example constructs a guide rail segment 222 and an arc segment 221 through a second slide rail, so that the connecting arm 13 can be well guided and limited by only one guide wheel 133. Specifically, during the rotation of the connecting arm 13, the guide wheel 133 is always inside the second slide rail 22, and the second slide rail 22 can effectively limit the guide wheel 133, so that the rotation of the connecting arm 13 is always limited, which is beneficial to the stability of the movement of the connecting arm 13, and thus beneficial to the stability of the sliding door 200.

[0117] In the above-mentioned technical method, by making the first slide rail 21 a straight rail extending in a straight line, it is beneficial to the stable movement of the first load-bearing wheel 123, the first limiting wheel 122, and the second limiting wheel 124, thereby improving the stability of the sliding assembly 10. The two-section arrangement of the second slide rail 22, through the cooperation of the arc-shaped section 221 and the guide wheel 133, can better enable the connecting arm 13 to rotate, thereby driving the sliding door 200 to move away from the vehicle body 100. Through the cooperation of the guide rail section 222 and the guide wheel 133, the sliding door 200 can also be limited and guided, thereby improving the stability of the sliding door 200.

[0118] In some embodiments of this application, such as Figures 8-11 As shown, the guide rail segment 222 can be parallel to the first slide rail 21.

[0119] In the above-mentioned technical method, the first slide rail 21, as a straight rail, can provide relatively stable linear motion support for the first load-bearing wheel 123 and the first limiting wheel 122, which is conducive to improving the accuracy and load-bearing capacity of the sliding of the load-bearing wheel and the first limiting wheel 122; in the segmented structure of the second slide rail 22, the guide rail segment 222 is parallel to the first slide rail 21 and distributed at intervals, which can not only avoid motion interference, but also make the motion trajectory of the connecting arm 13 more coordinated with the sliding posture of the first sliding bracket 121, which can better improve the stability of the sliding component 10.

[0120] In some embodiments of this application, such as Figures 8-11 As shown, the slide rail assembly 2 is a one-piece molded part.

[0121] For example, the slide rail assembly 2 can be integrally constructed by stamping and bending metal plates to form the first slide groove 211, the second slide groove 212 and the third slide groove 220. The integral molding method can make the slide rail assembly 2 have better consistency, and at the same time, it can also improve the structural strength of the slide rail assembly 2. This makes the slide rail assembly 2 less prone to deformation when connected to the sliding door 200 through the hinge module 1, thereby reliably opening or closing the sliding door 200.

[0122] Of course, it is understandable that the slide rail assembly 2 can also be constructed in other ways, such as 3D printing, which will not be elaborated in this application.

[0123] In the above-mentioned technical methods, the one-piece molding method can make the slide rail assembly 2 have better consistency, and at the same time, it can also improve the structural strength of the slide rail assembly 2. This makes the slide rail assembly 2 less prone to deformation when connected to the sliding door 200 through the hinge module 1, thereby reliably enabling the sliding door 200 to open or close.

[0124] This application also proposes a vehicle 1000 having the skid assembly 10 of the above embodiments.

[0125] like Figures 1-4 As shown, the vehicle 1000 according to an embodiment of this application includes a body 100, a sliding door 200 and a sliding connection structure. The sliding connection structure includes a sliding component 10 as described above. The sliding component 10 is connected between the body 100 and the sliding door 200 to allow the sliding door 200 to slide open or close relative to the body 100.

[0126] It should be noted that the vehicle 1000 may have sliding doors 200 on both its left and right sides. For ease of explanation, this application only describes the sliding door 200 on one side of the vehicle 1000, but this should not be construed as a limitation of this application. For example, the vehicle 1000 may have one sliding door 200 on each side, but this example only describes one sliding door 200 on one side of the vehicle 1000.

[0127] For example, the first mounting base 11 can be installed on the sliding door 200, the first slide rail 21 and the second slide rail 22 can be installed on the vehicle body 100, and the first slider 12 and the connecting arm 13 can be connected between the first mounting base 11 and the first slide rail 21 and the second slide rail 22, so that the sliding door 200 can be opened or closed more stably.

[0128] According to the vehicle 1000 of this application embodiment, by providing the sliding component 10 of the above embodiment, and by providing the first slide rail 21, the second slide rail 22 and the hinge module 1 of the above embodiment, the hinge module 1 can cooperate well with the two independent first slide rails 21 and the second slide rail 22. In this way, while guiding the first limiting wheel 122 and the guide wheel 133 respectively, it can also form a double constraint on the first slider 12 to a certain extent, thereby reducing the risk of the first slider 12 shaking during movement, making the hinge module operate more stably, and thus making the sliding door 200 open or close more stably.

[0129] In some embodiments of this application, such as Figures 1-4 As shown, the sliding assembly 10 is arranged at the bottom of the sliding door 200. The sliding connection structure also includes a middle guide rail assembly 20, which is arranged in the middle of the sliding door 200 and connected between the vehicle body 100 and the sliding door 200, so that the sliding door 200 can slide open or close relative to the vehicle body 100.

[0130] In other words, the sliding component 10 at the bottom of the sliding door 200 and the central guide rail component 20 in the middle of the sliding door 200 can effectively improve the stability of the sliding door 200 when opening and closing. Specifically, the sliding component 10 at the bottom bears the main load-bearing role and can provide stable bottom support for the sliding door 200. The central guide rail component 20 in the middle of the sliding door 200 can provide auxiliary positioning in the side of the sliding door 200, forming a constraint system that works together from top to bottom, which can effectively reduce the shaking and displacement of the sliding door 200 during the sliding process. Furthermore, the sliding assembly 10 of this application has a first load-bearing wheel 123, which can better support the sliding door 200. In addition, the sliding assembly 10 of this application also has good stability when the sliding door 200 slides through the sliding assembly 10 by the cooperation of the first limiting wheel 122 with the first slide groove 211, the cooperation of the second limiting wheel 124 with the second slide groove 212, and the cooperation of the guide wheel 133 with the third slide groove 220.

[0131] For example, the vehicle 1000 of this example can be equipped with an upper guide rail assembly according to actual needs. The upper guide rail assembly can be arranged on the upper part of the vehicle body 100. Of course, the upper guide rail assembly can also be omitted. This application does not limit this.

[0132] In the above-mentioned technical method, by arranging a sliding component with good stability at the bottom of the sliding door 200 and arranging a guide rail component 20 in the middle of the sliding door 200, a constraint system with upper and lower coordination can be formed in a better way, which can effectively reduce the shaking and displacement of the sliding door 200 during the sliding process.

[0133] In some embodiments of this application, such as Figures 1-4 As shown, the sliding connection structure consists of a sliding assembly 10 and a middle guide rail assembly 20. The sliding assembly 10 is arranged at the bottom of the sliding door 200, and the middle guide rail assembly 20 is arranged in the middle of the sliding door 200. The middle guide rail assembly 20 is connected between the vehicle body 100 and the sliding door 200, so that the sliding door 200 can slide open or close relative to the vehicle body 100.

[0134] In other words, the sliding connection structure of this application only includes the sliding component 10 and the middle guide rail component 20. Or, the sliding component is arranged only at the bottom of the sliding door 200, and the middle guide rail component is arranged in the middle of the sliding door 200. The upper part of the sliding door 200 does not need to be arranged with a guide structure. Similarly, there is no need to arrange a guide rail structure on the top of the vehicle body 100. The advantage of this is that the upper part of the sliding door 200 and the top of the vehicle body 100 can be better designed in terms of structure and appearance, thereby reducing the constraints on the external styling design of the vehicle 1000, which is conducive to improving the overall aesthetics of the vehicle 1000 and thus improving the user experience.

[0135] Furthermore, as can be seen from the above, the sliding component 10 at the bottom of the sliding door 200 and the central guide rail component 20 in the middle of the sliding door 200 can effectively improve the stability of the sliding door 200 when opening and closing. Specifically, the sliding component 10 at the bottom bears the main load-bearing function and can provide stable bottom support for the sliding door 200. The central guide rail component 20 in the middle of the sliding door 200 can provide auxiliary positioning in the side of the sliding door 200, forming a constraint system that works together from top to bottom, which can effectively reduce the shaking and displacement of the sliding door 200 during the sliding process. Furthermore, the sliding assembly 10 of this application has a first load-bearing wheel 123, which can better support the sliding door 200. In addition, the sliding assembly 10 of this application also has good stability when the sliding door 200 slides through the cooperation of the first limiting wheel 122 with the first slide groove 211, the cooperation of the second limiting wheel 124 with the second slide groove 212, and the cooperation of the guide wheel 133 with the third slide groove 220.

[0136] In the above-mentioned technical method, by arranging the sliding component 10 with good stability at the bottom of the sliding door 200 and arranging the guide rail component 20 in the middle of the sliding door 200, a constraint system with upper and lower coordination can be formed in a better way, which can effectively reduce the shaking and displacement of the sliding door 200 during the sliding process.

[0137] In some embodiments of this application, such as Figures 14-17As shown, the middle guide rail assembly 20 includes: a second mounting base 31, a middle guide rail 32, and a second slider 33. The second slider 33 includes a second sliding bracket 331, a third limiting wheel 332, and a second load-bearing wheel 333. The second mounting base 31 is rotatably connected to one end of the second sliding bracket 331. The third limiting wheel 332 and the second load-bearing wheel 333 are rotatably mounted on the other end of the second sliding bracket 331. The middle guide rail 32 includes a fourth sliding groove 321 and a track surface 322. The opening of the fourth sliding groove 321 faces downward, and the track surface 322 is arranged at the opening of the fourth sliding groove 321. The third limiting wheel 332 is fitted inside the fourth sliding groove 321, and the second load-bearing wheel 333 is fitted on the track surface 322.

[0138] In other words, the rotatable connection between the second mounting base 31 and the second sliding bracket 331 allows the middle guide rail assembly 20 to better adapt to changes in the movement angle of the sliding door 200, reducing motion interference caused by rigid connections. The third limiting wheel 332 can fit well into the downward-facing fourth slide groove 321, effectively limiting the vertical movement of the sliding door 200 in conjunction with the second load-bearing wheel 333, and also effectively limiting the axial sway of the second load-bearing wheel 333, enabling the middle guide rail assembly 20 to guide the sliding door 200 to slide more stably.

[0139] Furthermore, the second load-bearing wheel 333 cooperates with the track surface 322 to better bear the load in the middle of the sliding door 200. Combined with the first load-bearing wheel 123 located at the bottom of the sliding door 200, it can better support the sliding door 200, with high reliability and good stability. In the above-mentioned technical method, the second mounting base 31, the middle guide rail 32 and the second slider 33 are set by the middle guide rail assembly 20. The second load-bearing wheel 333 of the second slider 33 can be well matched with the first load-bearing wheel 123 to better support the sliding door 200. It has high reliability and good stability. The cooperation between the middle guide rail 32 and the third limit wheel 332 can better improve the stability of the sliding door 200.

[0140] In some embodiments of this application, such as Figures 14-17 As shown, at least two third limiting wheels 332 are provided, and the second load-bearing wheel 333 is located between two adjacent third limiting wheels 332 along the length direction of the middle guide rail 32.

[0141] In the above-mentioned technical method, the stability of the second load-bearing wheel 333 can be improved by using multiple third limiting wheels 332, thereby improving the stability of the sliding door 200 when sliding. By arranging the second load-bearing wheel 333 between two adjacent third limiting wheels 332, the limiting of the second load-bearing wheel 333 can be further improved, thereby further improving the stability of the second load-bearing wheel 333, and further improving the stability of the sliding door 200 when sliding.

[0142] This application also proposes a vehicle 1000 having the skid assembly 10 of the above embodiments.

[0143] like Figures 1-4 As shown, the vehicle 1000 according to an embodiment of this application includes a body 100, a sliding door 200, and a sliding connection structure. The sliding door 200 includes a first sliding door 201 and a second sliding door 202. The sliding connection structure includes a sliding component 10 as described in the above embodiment. The body 100 and the first sliding door 201, as well as the body 100 and the second sliding door 202, are connected by the sliding component 10, so that the first sliding door 201 and the second sliding door 202 close in a direction that approaches each other, or open in a direction that moves away from each other.

[0144] It should be noted that the vehicle 1000 may have sliding doors 200 on both its left and right sides. For ease of explanation, this application only describes the sliding door 200 on one side of the vehicle 1000, but this should not be construed as a limitation of this application. For example, the vehicle 1000 may have two sliding doors 200 on each side. In this example, only the two sliding doors 200 on one side of the vehicle 1000 are described. That is, the first sliding door 201 and the second sliding door 202 can be closed in a direction that brings them closer to each other or can be opened in a direction that moves them further apart from each other.

[0145] For example, taking the first sliding door 201 as an example, the first mounting base 11 can be installed on the first sliding door 201, the first slide rail 21 and the second slide rail 22 can be installed on the vehicle body 100, and the first slider 12 and the connecting arm 13 can be connected between the first mounting base 11 and the first slide rail 21 and the second slide rail 22, so that the first sliding door 201 can be opened or closed relatively stably. The second sliding door 202 has basically the same structure and the same opening and closing functions, so it will not be described in detail.

[0146] According to the vehicle 1000 of this application embodiment, by providing the sliding component 10 of the above embodiment, and by providing the first slide rail 21, the second slide rail 22 and the hinge module 1 of the above embodiment, the hinge module 1 can cooperate well with the two independent first slide rails 21 and second slide rails 22. In this way, while guiding the first limiting wheel 122 and the guide wheel 133 respectively, it can also form a double constraint on the first slider 12 to a certain extent. This can better reduce the risk of the first slider 12 shaking during movement, so that the hinge module can operate more stably. As a result, the first sliding door 201 and the second sliding door 202 can be opened or closed more stably.

[0147] In some embodiments of this application, such as Figures 1-4As shown, the sliding assembly 10 is arranged at the bottom of the sliding door 200. The sliding connection structure also includes a middle guide rail assembly 20, which is arranged in the middle of the sliding door 200 and connected between the vehicle body 100 and the sliding door 200, so that the sliding door 200 can slide open or close relative to the vehicle body 100.

[0148] In other words, the sliding component 10 at the bottom of the sliding door 200 and the central guide rail component 20 in the middle of the sliding door 200 can effectively improve the stability of the sliding door 200 when opening and closing. Specifically, the sliding component 10 at the bottom bears the main load-bearing role and can provide stable bottom support for the sliding door 200. The central guide rail component 20 in the middle of the sliding door 200 can provide auxiliary positioning in the side of the sliding door 200, forming a constraint system that works together from top to bottom, which can effectively reduce the shaking and displacement of the sliding door 200 during the sliding process. Furthermore, the sliding assembly 10 of this application has a first load-bearing wheel 123, which can better support the sliding door 200. In addition, the sliding assembly 10 of this application also has good stability when the sliding door 200 slides through the cooperation of the first limiting wheel 122 with the first slide groove 211, the cooperation of the second limiting wheel 124 with the second slide groove 212, and the cooperation of the guide wheel 133 with the third slide groove 220.

[0149] For example, the vehicle 1000 of this example can be equipped with an upper guide rail assembly according to actual needs. The upper guide rail assembly can be arranged on the upper part of the vehicle body 100. Of course, the upper guide rail assembly can also be omitted. This application does not limit this.

[0150] In the above-mentioned technical method, by arranging a sliding component with good stability at the bottom of the sliding door 200 and arranging a guide rail component 20 in the middle of the sliding door 200, a constraint system with upper and lower coordination can be formed in a better way, which can effectively reduce the shaking and displacement of the sliding door 200 during the sliding process.

[0151] In some embodiments of this application, such as Figures 1-4 As shown, the sliding connection structure consists of a sliding assembly 10 and a middle guide rail assembly 20. The sliding assembly 10 is arranged at the bottom of the sliding door 200, and the middle guide rail assembly 20 is arranged in the middle of the sliding door 200. The middle guide rail assembly 20 is connected between the vehicle body 100 and the sliding door 200, so that the sliding door 200 can slide open or close relative to the vehicle body 100.

[0152] In other words, the sliding connection structure of this application only includes the sliding component 10 and the middle guide rail component 20. Or, the sliding component is arranged only at the bottom of the sliding door 200, and the middle guide rail component is arranged in the middle of the sliding door 200. The upper part of the sliding door 200 does not need to be arranged with a guide structure. Similarly, there is no need to arrange a guide rail structure on the top of the vehicle body 100. The advantage of this is that the upper part of the sliding door 200 and the top of the vehicle body 100 can be structurally designed better, which can improve the flexibility of the shape of the vehicle 1000 roof, thereby improving the overall aesthetics of the vehicle 1000 and thus improving the user experience.

[0153] Furthermore, as can be seen from the above, the sliding component 10 at the bottom of the sliding door 200 and the central guide rail component 20 in the middle of the sliding door 200 can effectively improve the stability of the sliding door 200 when opening and closing. Specifically, the sliding component 10 at the bottom bears the main load-bearing function and can provide stable bottom support for the sliding door 200.

Furthermore, the sliding assembly 10 of this application has a first load-bearing wheel 123, which can better support the sliding door 200. In addition, the sliding assembly 10 of this application also has good stability when the sliding door 200 slides through the cooperation of the first limiting wheel 122 with the first slide groove 211, the cooperation of the second limiting wheel 124 with the second slide groove 212, and the cooperation of the guide wheel 133 with the third slide groove 220.

[0154] In the above-mentioned technical method, by arranging a sliding component with good stability at the bottom of the sliding door 200 and arranging a guide rail component 20 in the middle of the sliding door 200, a constraint system with upper and lower coordination can be formed in a better way, which can effectively reduce the shaking and displacement of the sliding door 200 during the sliding process.

[0155] In some embodiments of this application, such as Figures 14-17 As shown, the middle guide rail assembly 20 includes: a second mounting base 31, a middle guide rail 32, and a second slider 33. The second slider 33 includes a second sliding bracket 331, a third limiting wheel 332, and a second load-bearing wheel 333. The second mounting base 31 is rotatably connected to one end of the second sliding bracket 331. The third limiting wheel 332 and the second load-bearing wheel 333 are rotatably mounted on the other end of the second sliding bracket 331. The middle guide rail 32 includes a fourth sliding groove 321 and a track surface 322. The opening of the fourth sliding groove 321 faces downward, and the track surface 322 is arranged at the opening of the fourth sliding groove 321. The third limiting wheel 332 is fitted inside the fourth sliding groove 321, and the second load-bearing wheel 333 is fitted on the track surface 322.

[0156] In other words, the rotatable connection between the second mounting base 31 and the second sliding bracket 331 allows the middle guide rail assembly 20 to better adapt to changes in the movement angle of the sliding door 200, reducing motion interference caused by rigid connections.

[0157] Furthermore, the second load-bearing wheel 333 cooperates with the track surface 322 to better bear the load in the middle of the sliding door 200. Combined with the first load-bearing wheel 123 located at the bottom of the sliding door 200, it can better support the sliding door 200, with high reliability and good stability. In the above example, the second mounting base 31, the middle guide rail 32 and the second slider 33 are set by the middle guide rail assembly 20. The second load-bearing wheel 333 of the second slider 33 can be well matched with the first load-bearing wheel 123 to support the sliding door 200 well. It has high reliability and good stability. The cooperation between the middle guide rail 32 and the third limit wheel 332 can improve the stability of the sliding door 200.

[0159] In the above-mentioned technical method, the stability of the second load-bearing wheel 333 can be improved by using multiple third limiting wheels 332, thereby improving the stability of the sliding door 200 when sliding. By arranging the second load-bearing wheel 333 between two adjacent third limiting wheels 332, the limiting of the second load-bearing wheel 333 can be further improved, thereby further improving the stability of the second load-bearing wheel 333, and further improving the stability of the sliding door 200 when sliding.

[0160] In some embodiments of this application, such as Figures 1-4 As shown, the vehicle 1000 may also have a drive assembly 30, which can be connected to the central guide rail assembly 20 via a connecting structure such as a cable to realize the opening and closing of the sliding door 200.

[0161] In a specific example where the sliding door 200 is opened, the drive assembly 30 may include a drive motor, which can be connected to the second mounting base 31 of the middle guide rail assembly 20 via a cable, thereby enabling the automatic opening of the sliding door 200 through the drive assembly. The automatic closing of the sliding door 200 will not be described in detail here.
