Description

Technical Field

[0001] This application relates to the field of sliding door technology, and in particular to a sliding door system and a vehicle having the same. Background Technology

[0002] Sliding doors, with their unique opening mechanism, have gained widespread use in MPVs, SUVs, and some family sedans. Their core advantage lies in the smaller outward swing amplitude during opening; they primarily slide along the side of the vehicle, significantly reducing the amount of lateral space occupied. This is especially beneficial in narrow parking spaces and congested parking lots, effectively preventing collisions with surrounding vehicles or obstacles during opening. Simultaneously, they provide passengers with a more spacious aisle for getting in and out, significantly improving convenience and the overall riding experience.

[0003] In related technologies, in order to achieve the sliding opening and closing of sliding doors, it is usually necessary to open a groove feature on the outer surface of the vehicle body. When the sliding door is closed, the groove feature cannot be covered by the sliding door and is exposed on the surface of the vehicle body, which not only affects the aesthetics of the vehicle, but also increases the wind resistance of the vehicle to a certain extent and increases energy consumption. Utility Model Content

[0004] This application provides a sliding door system and a vehicle having the same, aiming to improve the problems of poor vehicle aesthetics and increased wind resistance caused by sliding door-related structures.

[0005] According to an embodiment of this application, the sliding door system includes a sliding door and a first sliding assembly. The first sliding assembly includes a first slide rail, which is installed on the inner side of the sliding door; a fixed wheel, which is installed on the inner side of the sliding door; and a first hinge module, which includes a first wheel assembly and a first hinge bracket. The first wheel assembly is slidably engaged with the first slide rail to allow the sliding door to move in a first direction. The first hinge bracket includes a connected first connecting arm and a guide rail. One end of the first connecting arm is rotatably connected to the vehicle body, and the other end of the first connecting arm is rotatably connected to the first wheel assembly. The guide rail is slidably engaged with the fixed wheel and is used to guide the rotation direction of the first connecting arm to allow the sliding door to move in a second direction, wherein the first direction is perpendicular to the second direction.

[0006] This application installs a first slide rail on the inside of the sliding door, with one end of a first hinge module mounted on the vehicle body and the other end slidingly engaged with the first slide rail. This allows the first slide rail and the first hinge module to achieve a natural, interference-free sliding engagement as the sliding door opens and closes, eliminating the need for grooves in the vehicle body. This results in a smooth, integrated appearance on the vehicle's exterior, improving aesthetics and reducing wind resistance. Furthermore, the guide rail of the first hinge module guides the rotation direction of the first connecting arm through a sliding engagement with a fixed wheel on the sliding door, allowing the sliding door to move in a second direction. The function of the sliding door moving in the second direction is primarily achieved through the structural design of the first hinge module. This allows for a smaller dimension of the first slide rail in the vehicle body width direction, facilitating its installation on the sliding door without being limited by the door's thickness.

[0007] In some embodiments of this application, the first connecting arm has a folded state and an unfolded state in the rotation direction of the first connecting arm. When the first connecting arm is in the folded state, the sliding door is in a first position of being closed.

One end of the curved section is connected to one end of the connecting section, and the other end of the curved section extends in a zigzag pattern so that when the first connecting arm rotates, the trajectory of the fixed wheel is an arc around the rotation axis of the first connecting arm.

[0010] In some embodiments of this application, the curved segment includes a first curved segment and a second curved segment. One end of the first curved segment is connected to the connecting segment, and the other end of the first curved segment is connected to one end of the second curved segment. The other end of the second curved segment is provided with the inlet and outlet. The opening of the first curved segment faces the second segment, and the opening of the second curved segment faces away from the second segment.

Detailed Implementation

[0050] 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.

[0051] 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.

[0052] 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.

[0053] Sliding doors, with their unique opening mechanism, have gained widespread use in MPVs, SUVs, and some family sedans. Their core advantage lies in the smaller outward swing amplitude during opening; they primarily slide along the side of the vehicle, significantly reducing the amount of lateral space occupied. This is especially beneficial in narrow parking spaces and congested parking lots, effectively preventing collisions with surrounding vehicles or obstacles during opening. Simultaneously, they provide passengers with a more spacious aisle for getting in and out, significantly improving convenience and the overall riding experience.

[0054] In related technologies, in order to achieve the sliding opening and closing of sliding doors, it is usually necessary to open a groove feature on the outer surface of the vehicle body. When the sliding door is closed, the groove feature cannot be covered by the sliding door and is exposed on the surface of the vehicle body, which not only affects the aesthetics of the vehicle, but also increases the wind resistance of the vehicle to a certain extent and increases energy consumption.

[0055] The inventors of this application recognized that in related technologies, sliding doors achieve their opening and closing by creating grooves on the outer surface of the vehicle body. This is because the sliding rail is mounted on the vehicle body, and the hinge is mounted on the sliding door. By creating grooves on the outer surface of the vehicle body at corresponding positions to the sliding rail, the hinge and the sliding rail can slide smoothly together without causing interference. Therefore, this application proposes the following solution to address the problems of poor vehicle aesthetics and increased wind resistance caused by the related structures of sliding doors.

[0056] The following is for reference. Figures 1-18 This application describes a sliding door system 100 according to an embodiment of the present application.

[0057] like Figures 1-6As shown in the embodiment of this application, a sliding door system 100 is provided. The sliding door system 100 includes a sliding door 200 and a first sliding assembly 10. The first sliding assembly 10 includes a first slide rail 1, a fixed wheel 2, and a first hinge module 3. The first slide rail 1 is installed on the inner side of the sliding door 200, and the fixed wheel 2 is installed on the inner side of the sliding door 200. The first hinge module 3 includes a first wheel set 31 and a first hinge bracket 32. The first wheel set 31 is slidably engaged with the first slide rail 1 to make the sliding door 200 move in a first direction. The first hinge bracket 32 ​​includes a first connecting arm 321 and a guide curved rail 322 connected together. One end of the first connecting arm 321 is rotatably connected to the vehicle body, and the other end of the first connecting arm 321 is rotatably connected to the first wheel set 31. The guide curved rail 322 is slidably engaged with the fixed wheel 2 and is used to guide the rotation direction of the first connecting arm 321 so that the sliding door 200 moves in a second direction, wherein the first direction is perpendicular to the second direction.

[0058] It should be noted that the inner side of the sliding door 200 refers to the side of the sliding door 200 facing the passenger compartment of the vehicle. The vehicle can be a vehicle, an aircraft, etc., and this application does not limit this. The first direction can be the front-rear direction of the sliding door 200, and the second direction can be the thickness direction of the sliding door 200. When the sliding door 200 is installed on the vehicle body, the first direction can be the front-rear direction of the vehicle body, and the second direction can be the left-right direction of the vehicle body.

[0059] Regarding the vehicle body in the above-mentioned technical method, it should be noted that the sliding door system 100 can be applied to vehicles or other equipment that requires the sliding door 200. This application does not limit this. The fact that one end of the first connecting arm 321 is rotatably connected to the vehicle body is for the convenience of describing the first connecting arm 321 in the first hinge module 3, but it cannot be used as a limitation of this application.

[0060] In the above-described technical method, during the opening of the sliding door 200, the force in the sliding direction of the sliding door 200 can be decomposed by the cooperation of the fixed wheel 2 and the guide curved rail 322. For example, when the sliding door 200 slides in the front-back direction, the force of the sliding door 200 in the front-back direction can be transmitted to the guide curved rail 322 through the fixed wheel 2. The guide curved rail 322 can be a curved track. Therefore, when the force on the fixed wheel 2 is transmitted to the guide curved rail 322, the guide curved rail 322 can have a component force that forms an angle with the front-back direction. Under the drive of this component force, the guide curved rail 322 can rotate relative to the fixed wheel 2, thereby driving the first connecting arm 321 to rotate relative to the vehicle body. For example, under the rotation of the first connecting arm 321, the sliding door 200 can be pushed away from the vehicle body, so that the sliding door 200 can be opened more smoothly.

[0061] More specifically, the first connecting arm 321 rotates, thereby pushing the sliding door 200 away from the vehicle body. Since one end of the first connecting arm 321 is rotatably connected to the vehicle body and the other end is rotatably connected to the door through the first wheel set 31, both ends of the first connecting arm 321 rotate relative to each other. Then, through the cooperation of the guide curved rail 322 and the fixed wheel 2, not only can the sliding door 200 be effectively pushed away from the vehicle body, but the posture of the sliding door 200 can also be restricted through the cooperation of the first wheel set 31 and the first slide rail 1. This allows the sliding door 200 to move stably along a fixed sliding trajectory. That is, during the sliding opening process of the sliding door 200, the degree of freedom of the sliding door 200 can be well restricted through the cooperation of the first wheel set 31 and the first slide rail 1, and through the cooperation of the fixed wheel 2 and the guide curved rail 322, so that the sliding door 200 can stably follow the rotation of the first connecting arm 321. Similarly, during the closing process of the sliding door 200, the first wheel assembly 31 and the first slide rail 1, the fixed wheel 2 and the guide curved rail 322 can also restrict the degree of freedom of the sliding door 200, so that the sliding door 200 can stably follow the rotation of the first connecting arm 321.

[0062] Furthermore, the first slide rail 1 is installed on the inner side of the sliding door 200, and one end of the first hinge module 3 is set on the vehicle body, while the other end slides in cooperation with the first slide rail 1. Thus, as the sliding door 200 opens and closes, the first slide rail 1 and the first hinge module 3 can naturally achieve a non-interference sliding cooperation, eliminating the need for groove features on the vehicle body. This results in a smooth, integrated appearance on the vehicle's outer surface, improving aesthetics and reducing wind resistance. In addition, since the guide rail 322 of the first hinge module 3 guides the rotation direction of the first connecting arm 321 through a sliding cooperation with the fixed wheel 2 on the sliding door 200, the sliding door 200 can move towards or away from the vehicle body. Therefore, the function of the sliding door 200 moving towards or away from the vehicle body is mainly achieved by the structural design of the first hinge module 3. This allows for a smaller dimension of the first slide rail 1 in the width direction of the vehicle body, facilitating its installation on the sliding door 200 without being limited by the door's thickness.

[0063] For example, the fixed wheel 2 may be spaced apart from the first slide rail 1.

[0064] According to the sliding door system 100 of this application embodiment, by installing a first slide rail 1 on the inner side of the sliding door 200, and cooperating with a first hinge bracket 32 ​​having a guide curved rail 322 and a fixed wheel 2 that can cooperate with the guide curved rail 322, the sliding door 200 can stably move in a direction away from or close to the vehicle body during opening or closing. It has high reliability and strong practicality. Furthermore, since the first slide rail 1 is installed on the inner side of the sliding door 200, there is no need to set a sliding groove feature. During the opening or closing of the sliding door 200, the vehicle body has no sliding groove feature exposed on the vehicle body surface, which helps to improve the aesthetics of the vehicle and reduce wind resistance.

[0065] In some embodiments of this application, such as Figures 1-6 As shown, the first slide rail 1 is formed as a straight rail extending along a first direction.

[0066] In order to achieve the outward and inward movement of the sliding door 200 during opening, the existing technology usually sets a curved section of a certain length on the slide rail. However, due to the thickness of the sliding door 200, the sliding door 200 cannot provide enough installation space for the slide rail with the curved section, so it is not possible to directly install the slide rail with the curved section on the sliding door 200. In this embodiment, the first slide rail 1 is set as a straight rail extending along a first direction and installed on the inside of the sliding door 200. The first slide rail 1 can be installed on the sliding door 200 without increasing the thickness of the sliding door 200, and the function of the curved section on the traditional slide rail is replaced by the first hinge module 3. Due to the rotational connection characteristics of the first hinge module 3 and the guiding effect of the guide curved rail 322, when the sliding door 200 is closed, the first hinge module 3 can rotate and fold to reduce the space occupied. Therefore, in this embodiment, the first hinge module 3 with guide curved rail 322 is used in conjunction with the straight rail that extends along the first direction inside the sliding door 200. This can solve the problem of vehicle aesthetics, reduce space occupation, and does not increase the thickness of the sliding door 200.

[0067] In addition, forming the first slide rail 1 as a straight rail can reduce the difficulty of processing and assembly, thereby reducing the cost of processing and assembly.

[0068] It is also understandable that the cooperation between the fixed wheel 2 and the first hinge module 3 designed in this application reduces the requirements for the shape of the first slide rail 1. That is, the first slide rail 1 can be a straight rail or a curved section with a shorter arc can be designed according to actual needs. This application does not impose any restrictions on this.

[0069] In some embodiments of this application, such as Figures 4-7 , Figure 11 and Figure 12As shown, the first connecting arm 321 has a folded state and an unfolded state in the rotation direction of the first connecting arm 321. When the first connecting arm 321 is in the folded state, the sliding door 200 is in the first closed position; when the first connecting arm 321 moves from the folded state to the unfolded state, the sliding door 200 is in the second position away from the vehicle body in the second direction; when the first connecting arm 321 remains in the unfolded state and moves along the first direction until the sliding door 200 is opened to its maximum position, the sliding door 200 is in the third position. The end of the guide rail 322 has an inlet / outlet 3031 that allows the fixed wheel 2 to enter and exit. When the sliding door 200 is in the second position, the fixed wheel 2 is located at the inlet / outlet 3031.

[0070] It should be noted that "the first connecting arm 321 has a folded state and an unfolded state" can be understood as either the first connecting arm 321 being able to be folded and unfolded, or it can be understood as the first connecting arm 321 not being able to be folded and unfolded, but being able to change its occupied size in the second direction by rotation. For example, when the first connecting arm 321 is rotated to a position where its occupied size in the second direction is small, the first connecting arm 321 is in the folded state; when the first connecting arm 321 is rotated to a position where its occupied size in the second direction is large, the first connecting arm 321 is in the unfolded state.

[0071] Combination Figure 12 As shown, at the end of the guide rail 322 away from the first connecting arm 321, the track groove of the guide rail 322 is provided with an opening, further connecting... Figures 4-6 As shown, when the sliding door 200 is opening, the fixed wheel 2 can move along the bending direction of the guide rail 322 relative to the guide rail 322, causing the first connecting arm 321 to rotate, thereby moving the sliding door 200 away from the vehicle body. At this time, when the sliding door 200 has moved away to the predetermined position, the fixed wheel 2 and the guide rail 322 do not need to cooperate in guiding it. That is, the sliding door 200 does not need to move away from the vehicle body, nor does it need to move closer to the vehicle body. At this time, the fixed wheel 2 can slide out of the guide rail 322 from the inlet / outlet 3031. In this way, the size of the guide rail 322 can be reduced, the material used in the guide rail 322 can be reduced, which is conducive to achieving lightweight design.

[0072] It should be further noted that the aforementioned "predetermined position" can be the second position, or any position between the second position and the third position along the first direction; this application does not impose any restrictions on this.

[0073] Furthermore, the limitation on the size of the guide rail 322 can also be understood as follows: the sliding of the sliding door 200 is actually achieved through the sliding cooperation between the first wheel assembly 31 and the first slide rail 1. The role of the guide rail 322 is to keep the sliding door 200 away from the vehicle body when it is open, or to keep the sliding door 200 close to the vehicle body when it is closed. This allows the guide rail 322 to have an inlet and outlet 3031, which can also facilitate the miniaturization design of the first hinge module 3, thereby facilitating the installation of the first hinge module 3. At the same time, it can also effectively reduce the interference of the guide rail 322 on the first connecting arm 321, the vehicle body, and the sliding door 200.

[0074] In some embodiments of this application, such as Figures 4-7 As shown. The first connecting arm 321 includes a first segment 3211, a second segment 3212 and a third segment 3213. The third segment 3213 is connected between the first segment 3211 and the second segment 3212. The ends of the first segment 3211 and the second segment 3212 that are away from the third segment 3213 both extend toward the same side of the third segment 3213. The first segment 3211 and the second segment 3212 are arranged at an acute angle. The first segment 3211 is rotatably connected to the vehicle body and the second segment 3212 is rotatably connected to the first wheel set 31.

[0075] In other words, both the first segment 3211 and the second segment 3212 bend towards the direction of the first slide rail 1, thus making the shape of the first connecting arm 321 resemble a hook. Figure 6 Taking the posture of the first connecting arm 321 when the sliding door 200 is in the closed position as an example, the first connecting arm 321 with its bent structure can better avoid the body and the components of the sliding door 200. For example, it can better avoid the sealing strip of the sliding door 200, thereby reducing the interference of the movement of the first connecting arm 321 on the body and the components of the sliding door 200.

[0076] In addition, the design of the shape of the first connecting arm 321 can also facilitate the arrangement of the guide rail 322 and the first wheel set 31. For example, it can leave installation space for the guide rail 322 and the first wheel set 31, which is conducive to the assembly of the first hinge module 3. Furthermore, the rotational connection position of the first connecting arm 321 with the vehicle body is close to the sliding door 200, which can facilitate the rotation of the first connecting arm 321 to move the sliding door 200 away from the vehicle body. When the sliding door 200 is in the closed position, it can occupy less space in the width direction of the vehicle, thus making the first hinge module 3 more compact, which is conducive to the assembly of the first hinge module 3 and also conducive to the spatial layout of components between the vehicle body and the sliding door 200.

[0077] Further integration Figure 11As shown, the angle between the first segment 3211 and the second segment 3212 is an acute angle, which can refer to the angle between the straight lines in which the first segment 3211 and the second segment 3212 extend along a straight line.

[0078] For example, the first connecting arm 321 can be a one-piece molded part, and the guide curved rail 322 can also be a one-piece molded part. The first connecting arm 321 and the guide curved rail 322 can be fixedly connected by welding or other means.

[0079] For example, the first hinge bracket 32 ​​may be a one-piece molded part.

[0080] In the above-mentioned technical method, by constructing the shape of the first connecting arm 321, the first connecting arm 321 can be in the shape of a hook, which can better avoid the components of the vehicle body and the sliding door 200. For example, it can better avoid the sealing strip of the sliding door 200, thereby reducing the interference of the movement of the first connecting arm 321 on the components of the vehicle body and the sliding door 200.

[0081] In some embodiments of this application, the guide curved rail 322 includes a connecting section 3221 and a curved section 3222. The connecting section 3221 is connected to the second section 3212 at an angle. One end of the curved section 3222 is connected to one end of the connecting section 3221, and the other end extends in a bend, so that when the first connecting arm 321 rotates, the relative motion trajectory of the fixed wheel 2 is an arc around the rotation axis of the first connecting arm 321.

[0082] like Figures 1-7 In the example shown, the first connecting arm 321 is rotatably connected to the vehicle body via a first pin, and the first connecting arm 321 is rotatably connected to the first wheel assembly 31 via a second pin. The first hinge bracket 32 ​​cooperates with the fixed wheel 2 via a guide rail 322, and the hinge bracket also cooperates with the first slide rail 1 via the first wheel assembly 31. During the process of the sliding door 200 being pushed open along the first direction (the first direction can be referenced to the front and rear direction of the vehicle body), the line connecting the axis of the first pin and the axis of the second pin forms an angle with the straight line of the first direction. Therefore, when the force is transmitted to the first connecting arm 321 through the sliding door 200 and the first wheel assembly 31, the first connecting arm 321 can rotate, thereby better pushing the sliding door 200 to move towards or away from the vehicle body. At the same time, through the cooperation of the fixed wheel 2 and the guide rail 322, the sliding door 200 can move towards or away from the vehicle body in a better way, limiting the rotation angle between the sliding door 200 and the first connecting arm 321, which is beneficial to the stability of the sliding door 200.

[0083] More specifically, in order to ensure the smooth rotation of the first connecting arm 321 while limiting the rotation angle between the sliding door 200 and the first connecting arm 321, the sliding door 200 moves synchronously with the fixed wheel 2 as the first connecting arm 321 rotates and drives the sliding door 200 to move. This causes the relative motion trajectory of the fixed wheel 2 to form an arc around the rotation axis of the first connecting arm 321. The guide curved rail 322 is connected to the first connecting arm 321. Therefore, the posture of the guide curved rail 322 continuously changes with the rotation of the first connecting arm 321. Thus, the bending state of the guide curved rail 322 can be designed according to the actual rotation of the first connecting arm 321 and the relative motion trajectory of the fixed wheel 2. Here, the bending direction and bending span of the guide curved rail 322 are not limited. The shape and size of the guide curved rail 322 can be designed according to actual needs. This application does not impose any restrictions on this.

[0084] In the above-mentioned technical method, by designing the structure of the guide curved rail 322, when the fixed wheel 2 and the guide curved rail 322 are engaged, the fixed wheel 2 can move relatively well within the guide curved rail 322 when it moves along the arc-shaped movement trajectory. At the same time, it can also better limit the rotation angle between the sliding door 200 and the first connecting arm 321, which is beneficial to the stability of the sliding door 200.

[0085] In some embodiments of this application, the curved segment 3222 includes a first curved segment 301 and a second curved segment 302. One end of the first curved segment 301 is connected to the connecting segment 3221, and the other end of the first curved segment 301 is connected to one end of the second curved segment 302. The other end of the second curved segment 302 is provided with an inlet / outlet 3031. The opening of the first curved segment 301 faces the second segment 3212, and the opening of the second curved segment 302 faces away from the second segment 3212.

[0086] Combination Figure 11 and Figure 12 As shown, the first curved section 301 and the second curved section 302 are formed in an "S" shape. During the rotation of the first connecting arm 321, the curved section 3222 can better match the rotation of the first connecting arm 321 and the relative motion trajectory of the fixed wheel 2, so that the curved section 3222 can better guide the fixed wheel 2 during the relative motion, so that the sliding door 200 moves closer to or away from the vehicle body.

[0087] The curvature of the first curved segment 301 and the second curved segment 302 can be the same or different, depending on the actual needs. In other words, when the actual rotation radius of the first connecting arm 321 changes and the distance between the fixed wheel 2 and the first slide rail 1 changes, the curvature of the first curved segment 301 and the second curved segment 302 also needs to change accordingly. The two curved segments 3222 of the present application with different curvature directions can better match the rotation of the first connecting arm 321 and the relative motion trajectory of the fixed wheel 2 after the curvature is adjusted adaptively.

[0088] In the above-mentioned technical method, by designing the shape of the curved section 3222, the curved section 3222 can better match the rotation of the first connecting arm 321 and the relative motion trajectory of the fixed wheel 2 during the rotation of the first connecting arm 321, so that the sliding door 200 can better approach or move away from the vehicle body.

[0089] In some embodiments of this application, the first connecting arm 321 and the guide rail 322 can be structural members extending in the same plane, or they can be arranged spaced apart in the vertical direction and then connected by connectors, for example... Figure 5 Taking the attached diagram as an example, we can... Figure 5 The positions of the guide rail 322 and the fixed wheel 2 are adjusted to reconstruct a shape different from the one in the middle. Figure 5 The shape of the first hinge bracket 32 ​​in another embodiment shown can also enable the fixed wheel 2 and the guide curved rail 322 to cooperate and make the first connecting arm 321 rotate. For example, the positions of the guide curved rail 322 and the fixed wheel 2 can be adjusted synchronously in the up and down direction. Therefore, this application does not limit the shape of the first connecting arm 321 and the guide curved rail 322.

[0090] In some embodiments of this application, the guide rail 322 includes a limiting section 3223 and a first limiting wheel 3224. One end of the limiting section 3223 is connected to the first connecting arm 321, and the other end of the limiting section 3223 is rotatably connected to the first limiting wheel 3224. The side wall of the first slide rail 1 is provided with a notch 111. When the first connecting arm 321 rotates, the first limiting wheel 3224 is adapted to enter and exit the first slide rail 1 through the notch 111. The first limiting wheel 3224 is adapted to cooperate with the first slide rail 1 to restrict the movement of the sliding door 200 in the second direction.

[0091] For example, refer to Figures 1-6As shown, when the sliding door 200 moves from the first position to the third position, the first limiting wheel 3224 is initially located outside the first slide rail 1. Through the cooperation of the fixed wheel 2 and the guide curved rail 322, the first connecting arm 321 can rotate. When the first connecting arm 321 rotates, the sliding door 200 moves away from the vehicle body, that is, the sliding door 200 moves from the first position to the second position. At this time, the cooperation of the fixed wheel 2 and the guide curved rail 322, and the cooperation of the first wheel assembly 31 and the first slide rail 1, make the sliding door 200 move stably from the first position to the second position. When the sliding door 200 moves to the second position, the fixed wheel 2 slides out from the inlet / outlet 3031 of the guide curved rail 322. At the same time, the first limiting wheel 3224 can enter the first slide rail 1 from the notch 111. As the sliding door 200 slides from the second position to the third position, the first limiting wheel 3224 will abut against the side wall of the first slide rail 1. Through the cooperation of the first limiting wheel 3224 and the first slide rail 1, the sliding door 200 is better limited in the second direction. At the same time, with the cooperation of the first wheel group 31 and the first slide rail 1, the sliding door 200 can slide more stably along the first direction.

[0092] For example, the first limiting wheel 3224 can enter the first slide rail 1 at the same time that the fixed wheel 2 slides out from the inlet / outlet 3031 of the guide curved rail 322, or it can enter the first slide rail 1 through the notch 111 before the fixed wheel 2 slides out from the inlet / outlet 3031 of the guide curved rail 322. This design allows the first limiting wheel 3224 to reliably enter the first slide rail 1, thereby improving the reliability of limiting the sliding door 200.

[0093] In the above-mentioned technical method, the cooperation between the first limiting wheel 3224 and the first slide rail 1 can effectively limit the sliding door 200 in the second direction, so that the sliding door 200 can slide relatively stably along the first direction.

[0094] In some embodiments of this application, after the fixed wheel 2 slides out from the inlet / outlet 3031, the first limiting wheel 3224 enters the first slide rail 1 through the notch 111.

[0095] It is understandable that the sliding out of the fixed wheel 2 from the inlet / outlet 3031 and the entry of the first limiting wheel 3224 into the first slide rail 1 through the notch 111 can occur simultaneously or sequentially. For example, the fixed wheel 2 may slide out of the inlet / outlet 3031 at the same time as the first limiting wheel 3224 enters the first slide rail 1 through the notch 111. Another example is that the fixed wheel 2 may first slide out of the inlet / outlet 3031, and then the first limiting wheel 3224 may enter the first slide rail 1 through the notch 111. Yet another example is that the first limiting wheel 3224 may first enter the first slide rail 1 through the notch 111, and then the fixed wheel 2 may slide out of the inlet / outlet 3031. This application does not impose any limitations on this.

[0096] In the above technical method, the sliding cooperation between the fixed wheel 2 and the guide curved rail 322 is mainly used to guide the rotation direction of the first connecting arm 321 and to constrain the first connecting arm 321. As the fixed wheel 2 slides out from the inlet / outlet 3031 of the guide curved rail 322, the first connecting arm 321 will lose its constraint and the sliding door 200 will lose its stability. By setting the first limiting wheel 3224 to enter the first slide rail 1 through the notch 111 after the fixed wheel 2 slides out from the inlet / outlet 3031, the first connecting arm 321 will be constrained by the first slide rail 1 to limit its movement in the second direction, so that the sliding door 200 can move stably in the first direction.

[0097] In some embodiments of this application, such as Figures 6-10 As shown, the first slide rail 1 includes a first slide groove 11 and a second slide groove 12 arranged at intervals in the vertical direction, with the second slide groove 12 located above the first slide groove 11; the first wheel assembly 31 includes: a first sliding bracket 311 and a first pulley 312, a first load-bearing wheel 313, and a second pulley 314 rotatably connected to the first sliding bracket 311. The first sliding bracket 311 is rotatably connected to the other end of the first connecting arm 321. The first pulley 312 is slidably fitted in the first slide groove 11, and the first load-bearing wheel 313 is adapted to support the first slide rail 1 (e.g., ...). Figure 8 As shown, the first slide rail 1 has a bearing surface 121), and the second pulley 314 is slidably fitted in the second slide groove 12. The rotation axis of the first pulley 312 is parallel to the rotation axis of the second pulley 314. The rotation axes of the first pulley 312 and the second pulley 314 are both arranged at an angle to the rotation axis of the first load-bearing wheel 313 to limit the position of the first load-bearing wheel 313. At least two first pulleys 312 are provided, and / or at least one second pulley 314 is provided.

[0098] In other words, the first slide rail 1 is provided with a first slide groove 11 (below) and a second slide groove 12 (above) at intervals to form a double guide rail; in the first wheel group 31, the first pulley 312 is embedded in the first slide groove 11 and the second pulley 314 is embedded in the second slide groove 12. The rotation axes of the two are parallel, which constrains the lateral displacement of the first load-bearing wheel 313 from the upper and lower dimensions to avoid shaking or derailment.

[0099] For example, two first pulleys 312 and one second pulley 314 are provided. Along the first direction, the first load-bearing wheel 313 is located between the two first pulleys 312. Thus, the first load-bearing wheel 313 directly bears the weight of the first slide rail 1 and related equipment. Its rotation axis forms an angle (usually 90°) with the axes of the first pulley 312 and the second pulley 314. Combined with the layout of "the first load-bearing wheel 313 is located between the two first pulleys 312", a triangular positioning structure is constructed, which can effectively prevent movement perpendicular to the sliding direction. When an external driving force is applied, the first pulley 312 slides along the first slide groove 11, the second pulley 314 slides along the second slide groove 12, and the first load-bearing wheel 313 rolls along the slide rail. The three move synchronously, ensuring directional accuracy through the double pulleys and stably transmitting the load by relying on the first load-bearing wheel 313, thus achieving smooth linear movement.

[0100] Exemplarily, there may be two second pulleys 314, with the first load-bearing wheel 313 located between the two second pulleys 314 along the first direction; or, exemplarily, there may be two first pulleys 312 and two second pulleys 314, with the first load-bearing wheel 313 located between the two first pulleys 312 and also between the two second pulleys 314 along the first direction. It is understood that this application will not elaborate on the number of first pulleys 312 and second pulleys 314 or their arrangement relative to the first load-bearing wheel 313.

[0101] In addition, the upper and lower double sliding grooves and double pulleys can effectively reduce the swaying of the first load-bearing wheel 313 when it moves. Furthermore, the first load-bearing wheel 313 bears the main load, and the multiple first pulleys 312 can help disperse the lateral force, which can effectively improve the load-bearing capacity of the first sliding assembly 10.

[0102] In the above-mentioned technical method, by setting the first slide groove 11 and the second slide groove 12 at an upper and lower interval, and with the first pulley 312 and the second pulley 314, the first load-bearing wheel 313 can be constrained to shift laterally in the upper and lower dimensions to avoid shaking or derailment.

[0103] In some embodiments of this application, such as Figures 1-3 , Figures 13-16 As shown, the sliding door system 100 also includes a second sliding assembly 20, which is arranged at intervals with the first sliding assembly 10 in the vertical direction. The second sliding assembly 20 includes a second slide rail 4 and a second hinge module 5. The second slide rail 4 is mounted on the vehicle body. The second hinge module 5 includes a mounting base 51, a second wheel set 52 and a second hinge bracket 53. The mounting base 51 is mounted on the inner side of the sliding door 200. The second wheel set 52 is adapted to slide with the second slide rail 4. The second hinge bracket 53 is rotatably connected between the mounting base 51 and the second wheel set 52.

[0104] For example, the mounting base 51 can be fixed to the inner side of the sliding door 200 by welding or riveting. The second hinge bracket 53 can be rotatably connected to the mounting base 51 and the second wheel set 52 by means of a pin. When the sliding door 200 slides, the rotation of the second hinge bracket 53 can make the sliding door 200 move closer to or away from the vehicle body. The second wheel set 52 can slide and cooperate well with the second slide rail 4 to guide the sliding direction of the sliding door 200.

[0105] In the above-mentioned technical method, the sliding door 200 can be stably slid by the vertical arrangement of the first sliding component 10 and the second sliding component 20. Furthermore, the second slide rail 4 of the second sliding component 20 is installed on the vehicle body, which can better enable the sliding door 200 to transfer gravity to the vehicle body through the second slide rail 4, thereby contributing to the stability of the entire vehicle.

[0106] In some embodiments of this application, such as Figures 1-3 , Figures 13-16 As shown, the second wheel assembly 52 includes: a second sliding bracket 521 and a third pulley 522 and a second load-bearing wheel 523 rotatably connected to the second sliding bracket 521. The rotation axis of the third pulley 522 is arranged at an angle to the rotation axis of the second load-bearing wheel 523. The third pulley 522 is used to limit the relative position between the second load-bearing wheel 523 and the second slide rail 4.

[0107] For example, the rotation axis of the third pulley 522 is perpendicular to the rotation axis of the second load-bearing wheel 523. That is, when the second load-bearing wheel 523 rolls on the second slide rail 4 to drive the sliding door 200 to slide, the third pulley 522 can restrict the position of the second load-bearing wheel 523 in the axial direction, so that the second load-bearing wheel 523 can roll more stably along the second slide rail 4, thereby making the sliding door 200 slide more stably.

[0108] In the above-mentioned technical method, when the second load-bearing roller 523 rolls on the second slide rail 4, the third pulley 522 can restrict the position of the second load-bearing roller 523, so that the second load-bearing roller 523 can roll more stably along the second slide rail 4, thereby making the sliding door 200 slide more stably.

[0109] In some embodiments of this application, the second sliding bracket 521 includes a first mounting surface and a second mounting surface, which are spaced apart or have an included angle. A third pulley 522 is mounted on the first mounting surface, and a second hinge bracket 53 is rotatably connected to the second mounting surface.

[0110] like Figures 1-3 , Figures 13-16As shown, the second sliding bracket 521 includes a first mounting plate 5211 and a second mounting plate 5212. The first mounting plate 5211 and the second mounting plate 5212 are spaced apart along the axial direction of the third pulley 522. The third pulley 522 is rotatably mounted on the first mounting plate 5211. The second hinge bracket 53 is rotatably connected to the second mounting plate 5212. When the second hinge bracket 53 rotates, the rotation surface of the second hinge bracket 53 is spaced apart from the rolling plane of the third pulley 522, so that the second hinge bracket 53 is less likely to interfere with the third pulley 522 during rotation. Furthermore, the spaced arrangement of the first mounting plate 5211 and the second mounting plate 5212 also separates the installation positions of the third pulley 522 and the second hinge bracket 53, which is beneficial for the installation between the third pulley 522 and the first mounting plate 5211, and between the second hinge bracket 53 and the second mounting plate 5212.

[0111] In addition, other implementation methods can be used for the structure of the second sliding bracket 521, the arrangement of the third pulley 522, and the hinge position between the second hinge bracket 53 and the second sliding bracket 521. For example, the second sliding bracket 521 has a first side, a second side, and a third side. The first side and the second side are located on opposite sides of the second sliding bracket 521, and the third side can be adjacent to the first side. For example, the third pulley 522 and the second load-bearing wheel 523 are both installed on the first side, and the second hinge bracket 53 is installed on the second side. For example, the third pulley 522 and the second load-bearing wheel 523 are both installed on the first side, and the second hinge bracket 53 is installed on the third side. That is, as long as the rotation plane of the third pulley 522 and the second load-bearing wheel 523 is spaced apart from the rotation plane of the second hinge bracket 53 in the vertical or horizontal direction, this application does not impose any restrictions on this.

[0112] In some embodiments of this application, such as Figures 1-3 , Figures 13-16 As shown, the axis of the third pulley 522 is in the up-down direction, the first mounting plate 5211 is located below the second mounting plate 5212, the second load-bearing wheel 523 is mounted on the first mounting plate 5211, at least two third pulleys 522 are provided, and the second load-bearing wheel 523 is located between two adjacent third pulleys 522.

[0113] In other words, both the second load-bearing roller 523 and the third pulley 522 are mounted on the first mounting plate 5211, which allows the third pulley 522 to effectively limit the second load-bearing roller 523. Furthermore, the third pulley 522 plays a major role in limiting the second load-bearing roller 523. Therefore, the diameter and material of the third pulley 522 can be controlled separately to improve the structural strength of the third pulley 522, thereby enabling it to reliably limit the second load-bearing roller 523.

[0114] Furthermore, the second load-bearing wheel 523 and the third pulley 522 are both mounted on the first mounting plate 5211, which has a relatively compact structure and can effectively reduce the size of the first hinge module 3 in the vertical direction, which is beneficial to the miniaturization design of the second hinge module 5.

[0115] In the above-mentioned technical method, by arranging the third pulley 522 and the second load-bearing wheel 523, the limiting effect of the third pulley 522 on the second load-bearing wheel 523 can be improved. Furthermore, by directly mounting the second load-bearing wheel 523 on the first mounting plate 5211, it is beneficial to improve the compactness of the second hinge module 5.

[0116] In some embodiments of this application, such as Figures 1-3 , Figures 13-16 As shown, the second wheel assembly 52 also includes a balance wheel 524, which is rotatably connected to the second sliding bracket 521. The rotation axis of the balance wheel 524 is parallel to the rotation axis of the second load-bearing wheel 523. In the first direction, the balance wheel 524 is located on the side of the second load-bearing wheel 523 away from the first hinge module 3. The balance wheel 524 is adapted to abut against the upper track surface 43 of the second slide rail 4, and the second load-bearing wheel 523 rolls against the lower track surface of the second slide rail 4. The lower track surface of the second slide rail 4 can be referenced to the third groove 41 described below. The opening of the third groove 41 faces upward, and the lower track surface of the second slide rail 4 can be the bottom surface of the third groove 41.

[0117] like Figure 1 In the initial stage of sliding door 200's movement, i.e., when sliding door 200 is in the first position, the distance between the first hinge module 3 and the second hinge module 5 is relatively large, and the center of gravity of sliding door 200 is between the first hinge module 3 and the second hinge module 5. The first hinge module 3 and the second hinge module 5 can effectively share the weight of sliding door 200. As sliding door 200 slides, i.e., from the first position to the third position, ... Figure 2 As shown, the distance between the first hinge module 3 and the second hinge module 5 gradually decreases, causing the center of gravity of the sliding door 200 to change relative to the first hinge module 3 and the second hinge module 5. Specifically, along the first direction, the second hinge module 5 gradually moves closer to the first hinge module 3, and the center of gravity of the sliding door 200 gradually moves towards the direction of the first hinge module 3. This makes it easy for the sliding door to shift in the vertical direction, which in turn makes the sliding door 200 prone to shaking, or even damage the first hinge module 3 and the second hinge module 5.

[0118] Based on this, in this embodiment, by setting a balance wheel 524 on the second sliding bracket 521, and making the balance wheel 524 and the second load-bearing wheel 523 spaced apart along the first direction, and the balance wheel 524 located on the side of the second load-bearing wheel 523 away from the first hinge module 3 in the first direction, when the center of gravity of the sliding door 200 changes, when the sliding door 200 transmits the upward lifting force to the second hinge module 5, the balance wheel 524 can press well against the upper track surface 43 of the second slide rail 4, and the upper track surface 43 transmits the downward reaction force to the balance wheel 524, making the second hinge module 5 less likely to be lifted upward, thereby making the sliding door 200 more stable during the process of sliding from the first position to the third position.

[0119] In the above-mentioned technical method, by setting the balance wheel 524, the change of the center of gravity of the sliding door 200 can be better adapted, so that the sliding door 200 can slide stably. At the same time, the first sliding component 10 and the second sliding component 20 can cooperate well to better balance the gravity from the sliding door 200, which can reduce the damage to the first sliding component 10 and the second sliding component 20.

[0120] In some embodiments of this application, such as Figures 1-3 , Figures 13-16 As shown, the sliding door 200 has a first position in a closed state and a third position in a fully opened state. In the first position, the center of gravity of the sliding door 200 is located between the first hinge module 3 and the balance wheel 524 in a first direction. In the third position, the first hinge module 3 is located between the center of gravity of the sliding door 200 and the balance wheel 524 in a first direction.

[0121] For example, along the first direction, the second hinge module 5 gradually approaches the first hinge module 3, and the center of gravity of the sliding door 200 gradually moves toward the first hinge module 3. As the sliding door 200 continues to slide, the center of gravity of the sliding door 200 will also pass the first hinge module 3, thereby causing the center of gravity of the sliding door 200 to move to the side of the first hinge module 3 away from the second hinge module 5. This makes it easy for the sliding door 200 to lift the second load-bearing wheel 523 around the first load-bearing wheel 313, which makes the sliding door 200 prone to shaking, or even damage the first hinge module 3 and the second hinge module 5.

[0122] By setting a balance wheel 524 on the second sliding bracket 521 and spacing the balance wheel 524 from the second load-bearing wheel 523 along the first direction, when the center of gravity of the sliding door 200 changes, and the sliding door 200 transmits the upward lifting force to the second hinge module 5, the balance wheel 524 can press well against the upper track surface 43 of the second slide rail 4. The upper track surface 43 transmits the downward reaction force to the balance wheel 524, making the second hinge module 5 less likely to be lifted upward, thereby making the sliding door 200 more stable during the process of sliding from the first position to the third position.

[0123] In some embodiments of this application, such as Figures 1-3 , Figures 13-16 As shown, the second hinge bracket 53 includes a second connecting arm 531 and a second limiting wheel 532. The second connecting arm 531 is rotatably connected between the mounting base 51 and the second wheel assembly 52. ​​The second limiting wheel 532 is rotatably connected to the second connecting arm 531. The second limiting wheel 532 is adapted to slide in cooperation with the second slide rail 4 to guide the rotation direction of the second connecting arm 531. The second slide rail 4 includes a third slide groove 41 and a fourth slide groove 42. The third pulley 522 and the second load-bearing wheel 523 are both slidably engaged in the third slide groove 41, and the second limiting wheel 532 is slidably engaged in the fourth slide groove 42.

[0124] like Figure 18 The third slide 41 has an upward opening, the fourth slide 42 has a downward opening, and the third slide 41 and the fourth slide 42 are arranged at intervals in the second direction.

[0125] In other words, a second limiting wheel 532 is provided on the second connecting arm 531. The second limiting wheel 532 is used to guide the rotation direction of the second connecting arm 531. The length and rotation angle of the second connecting arm 531 can control the distance of the sliding door 200 away from the vehicle body. Furthermore, by controlling the distance of the sliding door 200 away from the vehicle body, the posture of the sliding door 200 when it is opened can be adjusted, which can also better restrict the sliding door 200, so that the sliding door 200 can be opened more stably.

[0126] like Figure 17 and Figure 18In a specific example, the second slide rail 4 includes a first-layer track and a second-layer track. The third slide groove 41 is located on the first-layer track. The second slide rail 4 also includes a fifth slide groove. The openings of the third slide groove 41 and the fifth slide groove are opposite each other. The upper track surface 43, which cooperates with the balance wheel 524, is located on the bottom surface of the fifth slide groove. The fourth slide groove 42 and the fifth slide groove are both located on the second-layer track. In the second direction, the fifth slide groove and the fourth slide groove 42 are spaced apart. Through the above structural design, the third pulley 522, the second limiting wheel 532 and the balance wheel 524 are located in three different positions, and they are not likely to interfere with each other. The third pulley 522, the second limiting wheel 532 and the balance wheel 524 cooperate with the second slide rail 4, so that the second connecting arm 531 can be in a relatively stable unfolded state during the sliding door 200 sliding from the second position to the third position, which is not likely to affect the sliding of the sliding door 200 and is beneficial to the stability of the sliding door 200.

[0127] In the above-mentioned technical method, by setting a second connecting arm 531 and a second limiting wheel 532 rotatably connected to the second connecting arm 531, the second connecting arm 531 can be in a relatively stable unfolded state during the process of sliding the sliding door 200 from the second position to the third position, so as not to affect the sliding of the sliding door 200, which is beneficial to the stability of the sliding door 200.

[0128] In some embodiments of this application, such as Figure 17 and Figure 18 As shown, the fourth slide groove 42 includes a straight groove section 421 and a curved groove section 422. One end of the curved groove section 422 is connected to the straight groove section 421, and the other end is bent in a direction away from the sliding door 200, so that when the sliding door 200 slides, the curved groove section 422 cooperates with the second limit wheel 532 to make the sliding door 200 move in the second direction.

[0129] In the above-mentioned technical method, the curved groove section 422 can better guide the movement direction of the second limiting wheel 532, thereby enabling the second connecting arm 531 to rotate better, thus better guiding the sliding door 200 to approach or move away from the vehicle body. When the second limiting wheel 532 enters the straight groove section 421 from the curved groove section 422, the cooperation between the second limiting wheel 532 and the straight groove section 421 can better cooperate with the third pulley 522 and the third sliding groove 41 to limit the sliding of the sliding door 200, and can also better limit the second load-bearing wheel 523, resulting in good stability.

[0130] In some embodiments of this application, the sliding door system 100 further includes a third sliding component, wherein the first sliding component 10, the second sliding component 20 and the third sliding component are spaced apart along the vertical direction.

[0131] In other words, the sliding door 200 is equipped with a third sliding component, a first sliding component 10, and a second sliding component 20 at the top, middle, and bottom positions, respectively, which enables the sliding door 200 to achieve stable opening and closing.

[0132] For example, the structural features of the third sliding assembly can be exactly the same as those of the first sliding assembly 10. That is, the vehicle can have two first sliding assemblies 10, which are respectively arranged in the middle and top of the sliding door 200.

[0133] For example, the structural features of the third sliding assembly are exactly the same as those of the second sliding assembly 20, that is, the vehicle can have two second sliding assemblies 20, which are respectively arranged in the middle and top of the sliding door 200.

[0134] This application also proposes a vehicle having the first skid assembly 10 of the above embodiments.

[0135] According to this application, the vehicle includes a body and a sliding door system 100. The sliding door system 100 includes a first sliding component 10 of the above embodiment. In the vertical direction, the first sliding component 10 is located in the middle and / or lower part of the sliding door 200.

[0136] According to the vehicle of this application, by providing the first sliding component 10 of the above embodiment, the reliability and stability of the sliding door 200 can be improved, and the sliding door 200 has no exposed track during the sliding process, which is conducive to improving the aesthetics of the vehicle.

[0137] This application also proposes a vehicle having the sliding door system 100 of the above embodiments.

[0138] According to the vehicle of this application, the vehicle includes a body and a sliding door system 100. The sliding door system 100 consists of a sliding door 200, a first sliding assembly 10 and a second sliding assembly 20. In the vertical direction, the first sliding assembly 10 is located in the middle of the sliding door 200 and the second sliding assembly 20 is located at the bottom of the sliding door 200. That is, the sliding door 200 is slidably connected to the body only through the first sliding assembly 10 and the second sliding assembly 20.

[0139] Since the exterior design of the middle part of the vehicle body is more likely to attract consumers' attention and has a more significant visual effect, if a traditional sliding component is used in the middle part of the vehicle body, the outer surface of the middle part of the vehicle body will have obvious groove features, which will seriously affect the aesthetics of the vehicle. In this embodiment, by setting the first sliding component 10 in the middle of the sliding door 200, there is no need to open the groove features in the middle part of the vehicle body, so that the outer surface of the middle part of the vehicle body has a smooth and integrated shape, which can significantly improve the aesthetics of the vehicle. At the same time, it is also conducive to reducing wind resistance and energy consumption. Furthermore, the first sliding component 10 has a compact structure, which can effectively solve the problem of vehicle aesthetics, reduce space occupation, and does not easily increase the thickness of the sliding door 200.

[0140] By installing a second sliding assembly 20 at the bottom of the sliding door 200, the second sliding assembly 20 can better support the sliding door 200, allowing the sliding door 200 to transfer gravity to the vehicle body through the second sliding rail 4, thereby improving the stability of the entire vehicle. At the same time, the second sliding rail 4 can be installed on the vehicle's floor or door sill, eliminating the need for groove features on the vehicle body. Therefore, placing the second sliding assembly 20 at the bottom of the sliding door 200 does not affect the vehicle's aesthetics.

[0141] According to the vehicle of the present application embodiment, the first sliding component 10 and the second sliding component 20 are respectively provided in the middle and bottom of the sliding door 200. Through the coordinated cooperation of the first slide rail 1, the fixed wheel 2 and the first hinge module 3 of the first sliding component 10, and the second slide rail 4 and the second hinge module 5 of the second sliding component 20, the sliding door 200 can have sufficient sliding stability, so as to reduce the necessity of setting an additional sliding component on the top of the vehicle, and will not restrict the design of the exterior shape of the vehicle top, which can further improve the aesthetics of the vehicle.

[0142] This application also proposes a vehicle having the sliding door system 100 of the above embodiments.

[0143] According to the present application, the vehicle includes a body and a sliding door system 100. The sliding door system 100 includes a sliding door 200 and a first sliding assembly 10, a second sliding assembly 20, and a third sliding assembly disposed between the body and the sliding door 200. In the vertical direction, the first sliding assembly 10 is located in the middle of the sliding door 200, the second sliding assembly 20 is located at the bottom of the sliding door 200, and the third sliding assembly is located at the top of the sliding door 200.

[0144] In other words, the sliding door 200 is equipped with a third sliding component, a first sliding component 10, and a second sliding component 20 at the top, middle, and bottom positions, respectively, which enables the sliding door 200 to open and close more stably.

[0145] That is, by setting the first sliding component 10 in the middle of the sliding door 200, the vehicle body has no sliding groove features exposed on the vehicle body surface during the opening or closing of the sliding door 200, which helps to improve the aesthetics of the sliding door system 100. In addition, the first sliding component 10 has a compact structure, which can better solve the problem of vehicle aesthetics, reduce space occupation, and does not easily increase the thickness of the sliding door 200.

[0146] By setting a second sliding component 20 at the bottom of the sliding door 200, the second sliding component 20 can better support the sliding door 200, so that the sliding door 200 can transfer gravity to the vehicle body through the second slide rail 4, which is beneficial to the stability of the whole vehicle.

[0147] By setting a third sliding component at the top of the sliding door 200, the top of the sliding door 200 can be better constrained.

[0148] Therefore, with the combined action of the first sliding assembly 10, the second sliding assembly 20, and the third sliding assembly, the sliding door 200 can be opened and closed more stably.

[0149] For example, the structural features of the third sliding assembly can be exactly the same as those of the first sliding assembly 10. That is, the vehicle can have two first sliding assemblies 10, which are respectively arranged in the middle and top of the sliding door 200, which does not affect the aesthetics of the vehicle body and also helps to reduce wind resistance.

[0150] For example, the first slide rail 1 of the first sliding assembly 10 can be hidden in the interior panel of the sliding door 200, making it difficult for the user to notice and further improving the aesthetics of the vehicle.

[0151] Furthermore, the rotating connection in this application can be a pin connection or other connection methods, and this application does not impose any restrictions.

[0152] In this application, the sliding door 200 of the vehicle can be slid electrically or manually, and this application does not limit it in this regard.

[0153] The sliding door system 100 and other components and operations of the vehicle according to the embodiments of this application are known to those skilled in the art and will not be described in detail here.
