[0035] Please refer to FIG. 1 and FIG. 2, in some embodiments of the present application, the driving mechanism 3 further comprises a base 31, which is connected between the vehicle body 100 and the driving assembly 300. The base 31 is fixedly installed on the vehicle body 100, for example, below the rear seats of the passenger compartment of the vehicle. In this embodiment, the driving assembly 300 is connected with the vehicle body 100 through the base 31 fixedly installed on the vehicle body 100, which helps to improve the stability of the driving assembly 300 and ensure the reliability of the driving assembly 300 during operation. In FIG. 1 and FIG. 2, the base 31 can be fixedly installed on the vehicle body 100 by any means such as threaded connection, clamping connection or welding. In an embodiment, the base 31 and the vehicle body 100 are connected by threaded connection for easy disassembly.

[0036] As shown in FIG. 2, in some embodiments of the present application, the base 31 is provided with a limiting groove 311 with a preset shape on the first side a (i.e. one side in the thickness direction) in the first direction, and the limiting groove 311 extends at least partially towards the second side b (i.e. the other side in the thickness direction) of the base 31 in the first direction. In this embodiment, the swing assembly 400 is provided with a limiting portion 341 (to be described in detail below), at least part of which is slidably accommodated in the limiting groove 311 and in contact with the inner wall of the limiting groove 311. It should be noted that when the driving assembly 300 drives the swing assembly 400 to move, the limiting portion 341 slides in the limiting groove 311 and moves relative to the base 31. It can be understood that by reasonably designing the preset shape of the limiting groove 311 on the base 31, when the driving assembly 300 drives the swing assembly 400 to move, the limiting portion 341 slides along the limiting groove 311 with a preset shape, and the swing assembly 400 can drive the connected door 1 to move in a preset track, that is, the door 1 can be opened or closed relative to the vehicle body 100 in a side-slip manner and according to a preset track.

[0037] Please refer to FIG. 1 to FIG. 3, in some embodiments of the present application, the driving assembly 300 comprises a mounting member 32 and a driving member 33. The mounting member 32 is rotatably installed on the first side a of the base 31 in the first direction, that is, the driving assembly 300 is rotatably connected to the base 31 through the mounting member 32, and the rotation axis of the mounting member 32 relative to the base 31 extends in the first direction. The driving member 33 is installed on the vehicle body 100 and connected to the mounting member 32, and the driving member 33 drives the mounting member 32 to rotate relative to the base 31. In this embodiment, the driving assembly 300 is composed of two parts, the mounting member 32 and the driving member 33, which has a simple structure and is easy to install and maintain.

[0038] As shown in FIGS. 1-3, in some embodiments of the present application, the swing assembly 400 comprises a connecting seat 34 and a swing arm 35. The connecting seat 34 is arranged on the first side a of the base 31 in the first direction and is slidingly connected to the mounting member 32. The side of the connecting seat 34 facing the base 31 is provided with a limiting portion 341. The swing arm 35 has a first end 351 and a second end 352. The first end 351 of the swing arm 35 is fixedly connected to the connecting seat 34. The second end 352 of the swing arm 35 is configured to be rotationally connected to the door 1. In this embodiment, the swing assembly 400 is composed of two parts, i.e., the connecting seat 34 and the swing arm 35, and has the advantages of simple structure, easy installation and maintenance.

[0039] It should be noted that, in FIGS. 1-3, when the driving member 33 drives the mounting member 32 to rotate relative to the base 31, the connecting seat 34 moves relative to the base 31 by sliding in the limiting groove 311 through the limiting portion 341, and the connecting seat 34 can simultaneously slide relative to the mounting member 32, so as to ensure that the connecting seat 34 can drive the swing arm 35 to swing, so that the swing of the swing arm 35 drives the door 1 to open or close relative to the vehicle body 100 in a side-sliding manner. In this embodiment, the driving mechanism 3 has small volume of each component and convenient installation connection between components, has the advantages of simple overall structure and small space occupation in the passenger compartment, thereby helping to improve the comfort of the vehicle.

[0040] It can be understood that, in some embodiments of the present application, the components of the driving mechanism 3 can have different structural designs. The driving mechanism 3 provided by some embodiments of the present application will be further described in detail below with reference to FIGS. 1-7.

[0041] Please refer to FIG. 2 and FIG. 4, in some embodiments of the present application, the base 31 is a plate-shaped base with an outline substantially like an ear, and has a certain thickness to ensure structural strength, the thickness direction of the base 31 is the aforementioned first direction. As shown in FIG. 2 and FIG. 4, in the present embodiment, the base 31 includes one curved edge 313 and multiple straight edges 314 connected head to tail, the base 31 is provided with a limiting slot 311 at a position adjacent to the curved edge, the limiting slot 311 is provided on one side of the base 31 in the thickness direction and extends at least partially towards the other side of the base 31 in the thickness direction, in addition, the base 31 is provided with a mounting hole 312 at a position adjacent to one of the long straight edges opposite to the curved edge, the mounting hole 312 is used to rotatably mount the mounting member 32. In an embodiment, as shown in FIG. 2 and FIG. 4, the limiting slot 311 and the mounting hole 312 both extend through opposite sides of the base 31 in the thickness direction, which is beneficial to reduce the material consumption and weight of the base 31. In other embodiments, the limiting slot 311 and the mounting hole 312 can not extend through opposite sides of the base 31 in the thickness direction, as long as the limiting slot 311 can provide a sliding space to accommodate the limiting portion 341 of the connecting seat 34, and the mounting hole 312 can be used to rotatably mount the mounting member 32, which is not limited in this regard.

[0042] As shown in FIG. 4, in some embodiments of the present application, the limiting slot 311 specifically includes a first strip-shaped slot 3111 and an arc-shaped slot 3113 connected smoothly, the first strip-shaped slot 3111 is a straight slot extending along a straight line. In the present embodiment, when the limiting portion 341 (see FIG. 2) slides in the first strip-shaped slot 3111, the swing arm 35 drives the door 1 to open at a small angle relative to the vehicle body 100 (see FIG. 8); when the limiting portion 341 slides in the arc-shaped slot 3113, the swing arm 35 drives the door 1 to move in a side-sliding manner relative to the vehicle body 100, thereby opening or closing the entrance of the vehicle body 100 (see FIG. 10).

[0043] As shown in FIG. 4, the arc-shaped slot 3113 is a circular arc slot with a consistent radius of curvature, and the center of the arc-shaped slot 3113 is located on the rotation axis of the driving assembly 300 relative to the base 31 (i.e. the axis of the mounting hole 312). In this way, the swing arm 35 can drive the door 1 to move in a straight line when the door 1 moves in a side-sliding manner relative to the vehicle body 100, thereby improving the stability of the side-sliding movement of the door 1.

[0044] Of course, in other embodiments, the arc-shaped slot 3113 can also be a curve slot with varying radius of curvature, as long as the swing arm 35 can drive the door 1 to move in a side-sliding manner relative to the vehicle body 100 to open or close the entrance when the limiting portion 341 slides in the arc-shaped slot 3113.

[0045] As shown in FIG. 4, in some embodiments, the arc-shaped slot 3113 is connected to one end of the first strip-shaped slot 3111 close to the mounting hole 312, and the tangent line of the one end of the arc-shaped slot 3113 connected to the first strip-shaped slot 3111 forms a first included angle with the axis line of the first strip-shaped slot 3111, and the first included angle is an obtuse angle. In the present embodiment, by limiting the first included angle to be an obtuse angle, it can be ensured that when the limiting part 341 moves from the first strip-shaped slot 3111 to the arc-shaped slot 3113 or moves from the arc-shaped slot 3113 to the first strip-shaped slot 3111, the limiting part 341 can move smoothly without being blocked. Of course, in other embodiments, the first included angle can be a right angle, as long as it can ensure that the limiting part 341 can move between the first strip-shaped slot 3111 and the arc-shaped slot 3113.

[0046] As shown in FIG. 4, in some embodiments of the present application, the limiting slot 311 further comprises a second strip-shaped slot 3112, which extends along a straight line and is smoothly and transitionally connected to one end of the arc-shaped slot 3113 away from the first strip-shaped slot 3111. In the present embodiment, when the limiting part 341 (see FIG. 2) slides in the second strip-shaped slot 3112, the swing arm 35 drives the door 1 to close a certain angle (see FIG. 12) relative to the vehicle body 100 in the direction close to the vehicle body 100.

[0047] As shown in FIG. 4, in some embodiments, the tangent line of one end of the arc-shaped slot 3113 connected to the second strip-shaped slot 3112 forms a second included angle with the axis line of the second strip-shaped slot 3112, and the second included angle is an obtuse angle. In the present embodiment, by limiting the second included angle to be an obtuse angle, it can be ensured that when the limiting part 341 moves from the second strip-shaped slot 3112 to the arc-shaped slot 3113 or moves from the arc-shaped slot 3113 to the second strip-shaped slot 3112, the limiting part 341 can move smoothly without being blocked. Of course, in other embodiments, similar to the first included angle, the second included angle can also be a right angle, as long as it can ensure that the limiting part 341 can move between the second strip-shaped slot 3112 and the arc-shaped slot 3113.

[0048] It should be noted that, in some embodiments, referring to FIG. 4, when the door 1 is in a closed state relative to the vehicle body 100, the limiting portion 341 of the connecting seat 34 is located in the first slot 3111; when the driving member 33 drives the mounting member 32 to rotate relative to the base 31, so that the door 1 is opened in a side-sliding manner relative to the vehicle body 100, the limiting portion 341 will slide in the first slot 3111, the arc-shaped slot 3113 and the second slot 3112 in turn, so that the door 1 will experience three movement stages in the opening process, wherein the movement postures of the door 1 in the three movement stages are in turn: the rear end of the door is away from the vehicle body, the whole door is translated rearward, and the rear end of the door is close to the vehicle body. More details will be described below. The rear end of the door refers to the rear end of the door 1 in the front-rear direction of the vehicle, and correspondingly, the front end of the door 1 in the front-rear direction of the vehicle is the front end of the door.

[0049] As shown in FIG. 4, in some embodiments, the second included angle is the same as the first included angle, so that the distance of the rear end of the door 1 relative to the vehicle body 100 in the above two different movement stages is consistent, thereby ensuring that the door 1 is flush with the vehicle body 100 after being fully opened, which is beneficial to improve the overall appearance of the vehicle when the door is opened.

[0050] In other embodiments, the second included angle can also be smaller or larger than the first included angle, and the distance of the rear end of the door 1 relative to the vehicle body 100 in the above two different movement stages is different, so that the door 1 has a certain included angle (denoted as included angle A) with the vehicle body 100 after being fully opened, as long as the rear end of the door 1 does not contact the vehicle body 100.

[0051] Of course, in other embodiments, the limiting slot 311 can include the first slot 3111 and the arc-shaped slot 3113, but not the second slot 3112, which simplifies the structure of the limiting slot 311, and the door 1 only experiences two movement stages in the opening process, and the movement postures of the door 1 in the two movement stages are respectively that the rear end of the door is away from the vehicle body and the whole door is translated rearward, and the door 1 has a certain included angle (denoted as included angle B, which is greater than the included angle A) with the vehicle body 100 after being fully opened.

[0052] In some embodiments of the present application, the distance that the limiting portion 341 slides in the first or second strip-shaped slot 3111 or 3112 is directly proportional to the distance that the rear end of the door 1 moves away from or close to the vehicle body 100, and the distance that the limiting portion 341 slides in the arc-shaped slot 3113 is directly proportional to the distance that the door 1 as a whole slides laterally relative to the vehicle body 100. It can be understood that the extension length of the first or second strip-shaped slot 3111 or 3112, and the arc length and radius of the arc-shaped slot 3113, can be designed according to the actual requirements of different side sliding doors applied to different vehicles, respectively, and the aforementioned first and / or second included angles can adopt obtuse angles of different angles according to different designs of the arc-shaped slot 3113, which will not be limited or described herein.

[0053] Please refer to FIGS. 2 and 5, in some embodiments of the present application, the mounting member 32 is provided with at least one first sliding guide structure 321 on one side c in a second direction, the extension direction of the first sliding guide structure 321 is parallel to the surface of the base 31 on the first side a in the aforementioned first direction, and the second direction is perpendicular to the first direction (as shown in FIG. 2, one side of the second direction is c, and the other side of the second direction is d). The connecting seat 34 is provided with at least one second sliding guide structure 342 on the side facing the mounting member 32, and the second sliding guide structure 342 is in one-to-one sliding fit with the first sliding guide structure 321, so that the connecting seat 34 is slidingly connected to the mounting member 32.

[0054] As shown in FIGS. 2 and 5, the mounting member 32 includes a mounting member body 322 and a rotating shaft sleeve 323 connected to one end of the mounting member body 322, and the rotating shaft sleeve 323 is rotatably mounted to the base 31 on the first side a in the first direction. In the present embodiment, the mounting member body 322 is a plate body substantially in the shape of a cuboid column, the first sliding guide structure 321 is arranged on one side c of the mounting member body 322 in the second direction, i.e., on one side of the mounting member body 322 in the thickness direction; the rotating shaft sleeve 323 is in the shape of a cylinder and has a through hole passing through both ends in the axial direction, the through hole of the rotating shaft sleeve 323 movably penetrates the shaft peg 37, and the shaft peg 37 is fixedly inserted into the mounting hole 312 of the base 31, so that the rotating shaft sleeve 323 can rotate about the axis of the shaft peg 37 relative to the base 31, thereby rotatably mounting the mounting member 32 to the base 31. The shaft peg 37 can be replaced by other rotating members such as a rotating shaft.

[0055] As shown in FIG. 2 and FIG. 5, in some embodiments, the mounting member 32 is provided with at least two first guide sliding structures 321 on one side c of the mounting member 32 in the second direction (i.e. one side of the mounting member body 322 in the thickness direction), the at least two first guide sliding structures 321 are distributed in parallel and spaced apart along the first direction (i.e. the thickness direction of the base 31), and the side of the connecting seat 34 facing the mounting member 32 is provided with at least two second guide sliding structures 342 corresponding to the at least two first guide sliding structures 321. In this embodiment, the connecting seat 34 is movably connected to the mounting member 32 through the sliding fit of the at least two pairs of guide sliding structures, which can improve the connection reliability and the smoothness of relative sliding between the connecting seat 34 and the mounting member 32.

[0056] In other embodiments, the mounting member 32 can be provided with only one first guide sliding structure 321, and the connecting seat 34 is correspondingly provided with one second guide sliding structure 342, so that the connecting seat 34 is movably connected to the mounting member 32 through the sliding fit of the one pair of guide sliding structures.

[0057] As shown in FIG. 2 and FIG. 5, in some embodiments, one of the first guide sliding structure 321 and the second guide sliding structure 342 is a double-sided ball guide rail, and the other one is a guide sliding groove matched with the double-sided ball guide rail. The combination of the double-sided ball guide rail and the guide sliding groove not only reduces the shaking of the driving mechanism 3 when driving the door 1 to move, but also increases the contact area between the mounting member 32 and the connecting seat 34, and can improve the connection reliability and the smoothness of relative sliding between the connecting seat 34 and the mounting member 32, so that the door 1 is more stable during opening or closing.

[0058] Of course, in other embodiments, the first guide sliding structure 321 and the second guide sliding structure 342 can also adopt other combinations such as linear guide rails and linear guide sliding grooves, which are not limited.

[0059] It should be noted that, as shown in FIG. 2, in some embodiments of the present application, the driving member 33 drives the rotating shaft sleeve 323 to rotate relative to the base 31, and in turn drives the mounting member body 322 to rotate relative to the base 31. In an embodiment, as shown in FIGS. 2, 5 and 6, the mounting member 32 further comprises a connecting arm 324, one end of the connecting arm 324 is connected to the outer circumferential wall of the rotating shaft sleeve 323, and the connecting arm 324 and the mounting member body 322 are spaced apart along the circumferential direction of the rotating shaft sleeve 323, and the driving member 33 is drivingly connected to the connecting arm 324, and the driving member 33 drives the connecting arm 324 to swing around the axis of the rotating shaft sleeve 323 to drive the rotating shaft sleeve 323 to rotate relative to the base 31. As shown in FIGS. 2, 5 and 6, the mounting member 32 is provided with the connecting arm 324 connected to the rotating shaft sleeve 323, and the driving member 33 is drivingly connected to the connecting arm 324, so that a force arm can be formed between the connecting arm 324 and the rotating shaft sleeve 323, thereby reducing the driving force of the driving member 33 to drive the connecting arm 324 to swing around the axis of the rotating shaft sleeve 323, so that the driving member 33 can more smoothly drive the rotating shaft sleeve 323 to rotate relative to the base 31.

[0068] The three movement stages of the vehicle door 1 in the opening process of the vehicle side sliding door assembly 200 provided by some embodiments of the present application will be described in detail below in combination with FIG. 1, FIG. 2, FIG. 8 to FIG. 13.

[0069] Please combine Figure 8 and Figure 9, the first movement stage of the door 1 in the process of opening the door is: when the telescopic rod (i.e. the driving member 33) starts to shorten, the telescopic rod drives the connecting arm 324 to start rotating around the axis of the rotating shaft sleeve 323, so as to drive the whole mounting member 32 to rotate relative to the base 31. Under the limiting action of the limiting groove 311, the limiting part 341 slides in the first slot 3111 to the side close to the arc-shaped groove 3113 at the connection of the first slot 3111 and the arc-shaped groove 3113. In this process, the connecting seat 34 moves linearly along the extension direction of the first slot 3111 relative to the base 31, and under the sliding cooperation of the first guide sliding structure 321 and the second guide sliding structure 342, the connecting seat 34 slides relative to the mounting member 32. The movement of the connecting seat 34 drives the swing arm 35 to move linearly along the extension direction of the first slot 3111, and the swing arm 35 drives the door 1 to move linearly along the extension direction of the first slot 3111. Under the joint action of the driving mechanism 3 and the connecting rod mechanism 2, the front end and the rear end of the door 1 will produce a certain deflection, so that the rear end of the door 1 opens a small angle away from the vehicle body 100, which can avoid the contact and interference between the door 1 and the vehicle body 100 in the subsequent side sliding movement.

[0070] Please combine Figure 10 and Figure 11, the second movement stage of the door 1 in the process of opening the door is: the telescopic rod continues to shorten, driving the mounting member 32 to further rotate relative to the base 31. Under the limiting action of the limiting groove 311, the limiting part 341 slides from the first slot 3111 into the arc-shaped groove 3113 and slides in the arc-shaped groove 3113 to the side close to the second slot 3112, and slides to the connection of the arc-shaped groove 3113 and the second slot 3112. Since the radius of the arc-shaped groove 3113 is constant, the connecting seat 34 starts to drive the swing arm 35 to move along the arc-shaped groove 3113 in a curved manner, so that the swing arm 35 drives the door 1 to translate to the rear of the vehicle in a side sliding manner.

[0071] Please combine Figure 12 and Figure 13, the third movement stage of the door 1 in the process of opening the door is: the telescopic rod continues to shorten, driving the mounting member 32 to further rotate relative to the base 31. Under the limiting action of the limiting groove 311, the limiting part 341 slides from the arc-shaped groove 3113 into the second slot 3112 and slides in the second slot 3112 away from the arc-shaped groove 3113. In this process, the connecting seat 34 moves linearly along the extension direction of the second slot 3112 relative to the base 31, and under the sliding cooperation of the first guide sliding structure 321 and the second guide sliding structure 342, the connecting seat 34 slides relative to the mounting member 32. The connecting seat 34 drives the swing arm 35 to move linearly along the extension direction of the second slot 3112. Under the joint action of the driving mechanism 3 and the connecting rod mechanism 2, the rear end of the door 1 swings a small angle close to the vehicle body 100 until the door 1 is flush with the vehicle body 100, and the door 1 is completely opened.

[0072] It can be understood that the corresponding actions of the vehicle side sliding door assembly 200 in the closing process of the door 1 are opposite to the corresponding actions of the vehicle side sliding door assembly 200 in the opening process of the door 1, and details are not described herein.
