Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0047] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0048] The electric limiter 340 in the vehicle is used to automatically open or close the door 200 to open or close the doorway for people to enter or exit.

[0049] However, currently, the electric limiter 340 in the vehicle is connected to the side of the door opening of the door 200 at one end of the vehicle body 100. The side of the door opening is small in the width direction Y of the vehicle body 100, and the distance between the electric limiter 340 and the door 200 is small. This results in a small lever arm for the output torque of the electric limiter 340, which in turn results in a small output torque and makes it difficult to adapt to the door 200 opening method that requires a large torque.

[0050] To address the technical issue of the aforementioned electric limiter 340's inability to output large torque, please refer to... Figure 1 and Figure 2 The vehicle includes a body 100, a door 200, a drive assembly 300, and a support member 400. The door 200 is rotatably connected to the body 100. The drive assembly 300 is connected to the side of the door 200 closest to the body 100. One end of the support member 400 is rotatably connected to the drive assembly 300, and the other end is rotatably connected to the body 100. The support member 400 can rotate relative to the body 100 to rotate the door 200. The width direction Y is the direction indicated by the arrow Y in the attached drawing.

[0051] Specifically, the drive assembly 300 can drive the end of the support member 400 that is rotatably connected to the drive assembly 300 to reciprocate along the first direction O, so that the support member 400 can rotate relative to the vehicle body 100, thereby enabling the support member 400 to drive the door 200 to rotate, realizing the automatic opening and closing of the door 200. The first direction O is the direction indicated by arrow O in the attached drawing.

[0052] In some embodiments, one end of the support member 400 is rotatably connected to the side of the drive assembly 300 near the vehicle body 100; in some embodiments, one end of the support member 400 is rotatably connected to the side of the drive assembly 300 along the height direction Z, specifically, one end of the support member 400 is rotatably connected to the side of the drive assembly 300 near the vehicle support plane, or one end of the support member 400 is rotatably connected to the side of the drive assembly 300 away from the vehicle support plane. Here, the height direction Z is the direction indicated by arrow Z in the figures, and the width direction Y intersects with the height direction Z.

[0053] In some embodiments, one end of the support member 400 is rotatably connected to the side of the vehicle body 100 near the door 200; in some embodiments, one end of the support member 400 is rotatably connected to the side of the vehicle body 100 along the height direction Z, specifically, one end of the support member 400 is rotatably connected to the side of the vehicle body 100 near the vehicle support plane.

[0054] Understandably, please refer to Figure 7 , Figure 8 and Figure 9 In the attached diagram, the dashed line represents the lever arm of the torque output by the support member 400 when rotating the car door. When the support member 400 drives the car door 200 to rotate, the car door 200 rotates around the rotation axis 210. The length L of the lever arm of the torque output by the support member 400 when rotating the car door 200 is the minimum distance between the straight line containing the rotation axis 210 and the straight lines containing both ends of the support member 400.

[0055] In some embodiments, the drive assembly 300 and the support member 400 may be connected between the front door and the vehicle body 100 for rotating the front door; in some embodiments, the drive assembly 300 and the support member 400 may be connected between the rear door and the vehicle body for rotating the rear door; in some embodiments, the drive assembly 300 and the support member 400 are connected between the front door and the vehicle body 100, and the drive assembly 300 and the support member 400 are also connected between the rear door and the vehicle body 100; in some embodiments, where the vehicle adopts a pillarless double-door design, the drive assembly 300 and the support member 400 are connected between the front door and the vehicle body 100, and the drive assembly 300 and the support member 400 are also connected between the rear door and the vehicle body 100 to enable the opening and closing of the front and rear doors.

[0056] In the above embodiment, the maximum dimensions of the vehicle body 100 and the door 200 along the width direction Y of the vehicle body 100 are relatively large. This allows the end of the support member 400 connected to the vehicle body 100 to be as far away from the rotation axis 210 as possible, thereby maximizing the lever arm length L. This enables the support member 400 to drive the door 200 to rotate with a greater torque. Simultaneously, since the size of the support member 400 is smaller than that of the drive assembly 300, and the connection method of the drive assembly 300 to the door 200 and the support member 400 to the vehicle body 100 simplifies the process. This means the vehicle body 100 only needs a smaller hole to connect the smaller support member 400, reducing the impact of the connection hole 121 on the strength of the vehicle body 100 and improving vehicle performance. Furthermore, with the same output torque, a larger lever arm length L allows the drive assembly 300 to output less power, resulting in a smaller drive assembly 300 and a more compact vehicle structure.

[0057] In some embodiments, please refer to Figure 1 and Figure 2 The support member 400 is connected to one side of the vehicle body 100 along the height direction Z of the vehicle body 100.

[0058] In some embodiments, the support member 400 is rotatably connected to the side of the vehicle body 100 facing the vehicle support plane along the height direction Z of the vehicle body 100. Specifically, at least a portion of the support member 400 is located on the side of the vehicle body 100 closer to the vehicle support plane.

[0059] In the above embodiment, one end of the support member 400 is connected to one side of the vehicle body 100 along the height direction Z. This allows one end of the support member 400 to be as far away as possible from the straight line where the rotation axis 210 is located in the width direction Y and length direction X of the vehicle body 100, thereby enabling the support member 400 to obtain greater torque when driving the door 200 to rotate. Furthermore, since the support member 400 is connected to one side of the vehicle body 100 along the height direction Z, it means that a portion of the support member 400 is located on one side of the vehicle body 100 along the height direction Z. When the door 200 is closed, the total dimension along the width direction Y of the portion of the drive assembly 300 and the support member 400 located between the door 200 and the vehicle body 100 is smaller. This allows the dimension in the width direction Y of the portion connecting the vehicle body 100 and the support member 400 to be larger, improving the strength of the vehicle body 100 and thus enhancing vehicle performance. The length direction X is the direction indicated by arrow X in the attached figures. The width direction Y, height direction Z, and length direction X intersect each other.

[0060] In some embodiments, please refer to Figure 3 The body 100 has a connection hole 121, and the support member 400 passes through the connection hole 121.

[0061] Specifically, the support member 400 includes a first connecting end 410, a second connecting end 420, a first connecting member 450, and a second connecting member 460. The first connecting end 410 is connected to the first connecting member 450, and the first connecting member 450 is rotatably connected to the drive assembly 300. The second connecting end 420 is connected to the second connecting member 460, and the second connecting member 460 passes through the connecting hole 121 and is rotatably connected to the vehicle body 100.

[0062] In some embodiments, the first connector 450 is a spherical bearing.

[0063] In some embodiments, the second connector 460 is a spherical bearing.

[0064] In the above embodiments, since the connecting hole 121 only needs to ensure that the first connector 450 can pass through and that the first connector 450 can rotate within the connecting hole 121, the area required for the connecting hole 121 is small, the body 100 has better strength, and the vehicle has better performance.

[0065] In some embodiments, please refer to Figure 2 The drive assembly 300 is connected to the support member 400 on the side of the body 100 along the height direction Z.

[0066] Specifically, the support member 400 is located on the same side of the drive assembly 300 and the vehicle body 100 along the height direction Z.

[0067] In some embodiments, the support member 400 is located on the side of the drive assembly 300 near the vehicle support plane, and the support member 400 is located on the side of the vehicle body 100 near the vehicle support plane.

[0068] In the above embodiment, by setting the support member 400 on the same side of the drive assembly 300 and the body 100 along the height direction Z, the space between the door 200 and the body 100 along the width direction Y does not need to be reserved for the support member 400. This allows the part connecting the body 100 and the support member 400 to have a larger dimension along the width direction Y, thereby obtaining better mechanical properties and improving the performance of the vehicle.

[0069] In some embodiments, please refer to Figure 7 , Figure 8 and Figure 9 The drive assembly 300 includes a guide 310, a connector 320, and a driver 330. The guide 310 is connected to the door 200; the connector 320 is connected to the guide 310 and is rotatably connected to the support 400; the driver 330 is connected to the connector 320 and is capable of driving the connector 320 to move along a first direction O.

[0070] In some embodiments, the actuator 330 is an electric push rod.

[0071] In some embodiments, the guide member 310 is a guide rail, and the connector 320 is slidably connected to the guide rail and guided by the guide member 310 along the first direction O.

[0072] In the above embodiment, by setting the guide member 310 to guide the connector 320 along the first direction O, the possibility of the connector 320 deviating from the predetermined trajectory when moving along the first direction O is reduced, thereby reducing the possibility of the connector 320 getting stuck during movement, making the operation of the drive assembly 300 and the support member 400 smoother, and the opening and closing of the door 200 also smoother, reducing the possibility of the door 200 getting stuck during opening and closing, and improving the reliability of the vehicle.

[0073] In some embodiments, please refer to Figure 7 , Figure 8 and Figure 9 The driver 330 includes a transmission part 331 and a drive part 332. The transmission part 331 passes through the connector 320, and the guide part 310 can restrict the rotation of the connector 320. The drive part 332 is connected to one end of the transmission part 331, and the drive part 332 can rotate the transmission part 331 to drive the connector 320 to move along the first direction O.

[0074] In some embodiments, the transmission part 331 is a lead screw with external threads, the drive part 332 is a motor capable of rotating the lead screw, and the connecting member 320 is a nut with internal threads that is sleeved on the lead screw. When the transmission part 331, as the lead screw, drives the connecting member 320, as the nut, to move, it can withstand a large axial load, output a large force, and also obtain good motion stability.

[0075] In some embodiments, the guide 310 of the connector 320 can restrict the rotation of the connector 320 to prevent the connector 320 from rotating with the transmission part 331, thereby enabling the connector 320 to rotate relative to the transmission part 331 and be driven by the transmission part 331 to move along the first direction O.

[0076] In the above embodiment, a rotatable transmission part 331 is provided to drive the connecting member 320 to move along the first direction O. This allows the drive assembly 300 to output a large torque when driving the door 200 to rotate via the support member 400, thus adapting to door opening methods that require high torque. Simultaneously, it also ensures smoother opening and closing of the door 200.

[0077] In some embodiments, please refer to Figure 10 The door 200 can rotate relative to the body 100 around the rotation axis 210; the drive unit 332 is connected to the side of the transmission unit 331 away from the line where the rotation axis 210 is located.

[0078] Specifically, along the width direction Y of the vehicle body 100, the straight line where the rotation axis 210 is located has a first orthographic projection 211 in the longitudinal symmetry plane of the vehicle body 100; the transmission unit 331 has a second orthographic projection 333 in the longitudinal symmetry plane of the vehicle body 100, and the drive unit 332 has a third orthographic projection 334 in the longitudinal symmetry plane of the vehicle body 100. The third orthographic projection 334 is located on the side of the second orthographic projection 333 that is away from the first orthographic projection 211.

[0079] Specifically, the transmission unit 331 is connected to the side of the drive unit 332 that is close to the straight line of the rotation shaft 210.

[0080] Understandably, one end of the support member 400 is rotatably connected to the connector 320, and the connector 320 is connected to the transmission unit 331. The position where one end of the support member 400 is connected to the vehicle body 100 is determined; the closer the transmission unit 331 is to the straight line where the rotation shaft 210 is located, the shorter the length of the support member 400.

[0081] In the above embodiment, by positioning the transmission part 331 closer to the line of the rotation shaft 210 than the drive part 332, the length of the support member 400 is shortened as much as possible. This results in better rigidity of the support member 400, reducing the likelihood of deformation when the door 200 is rotated, and ensuring smoother rotation of the door 200. Furthermore, the shorter support member 400 also reduces the likelihood of collisions between the door and the support member after the door 200 is opened, improving vehicle comfort.

[0082] In some embodiments, please refer to Figure 6 The connector 320 has a limiting groove 321 on one side perpendicular to the first direction O; the drive assembly 300 also includes a limiting member 340, which is connected to the guide member 310 and can enter the limiting groove 321 in a direction perpendicular to the first direction O.

[0083] Specifically, when the limiting member 340 enters the limiting groove 321, the limiting member 340 abuts against the groove wall of the limiting groove 321 along the first direction O, and limits the connecting member 320 along the first direction O, so that the door 200 can be suspended during rotation. When the drive unit 332 continues to work or the door 200 is driven by a large external force, the limiting member 340 will move out of the limiting groove 321 so that the door 200 can continue to rotate.

[0084] In some embodiments, the external force is the force applied by a person to the door 200.

[0085] In the above embodiment, a limiter is provided so that the door 200 can be limited after rotation stops.

[0086] In some embodiments, the drive assembly 300 includes a plurality of limiting members 340, which are spaced apart along a first direction O.

[0087] In some embodiments, a plurality of limiting members 340 spaced apart along the first direction O can respectively limit the connector 320 along the first direction O and form a plurality of limiting points. The plurality of limiting points include at least a first limiting point. When the door 200 is closed, the connector 320 is located at the first limiting point, so as to reduce the probability of the door 200 being accidentally opened when the door 200 is closed. Figure 7 The connector 320 is located at the first limiting point.

[0088] In some embodiments, the plurality of limiting points further include a second limiting point. When the door 200 is opened to its maximum angle, the connector 320 is located at the second limiting point to reduce the probability of the door 200 accidentally closing when the door 200 is opened to its maximum angle. Figure 9 The connector 320 is located at the second limiting point.

[0089] In some embodiments, the plurality of limiting points further includes a third limiting point, which is located between the first limiting point and the second limiting point along the first direction O. When the door 200 is located between the position opened to its maximum angle and the closed position, the connector 320 is located at the third limiting point, so that the door 200 remains suspended during opening, reducing the possibility of the door 200 accidentally opening or closing further. Figure 8 The connector 320 is located at the third limiting point.

[0090] In the above embodiment, multiple limiting members 340 are set to limit the door 200 when it is at different angles, so as to make the use of the door 200 more convenient and improve the comfort of vehicle use.

[0091] In some embodiments, please refer to Figure 6 The limiting member 340 includes an elastic part 341 and a limiting part 342. One end of the elastic part 341 is connected to the guide member 310; the limiting part 342 is connected to the other end of the elastic part 341, and at least a portion of the limiting part 342 can enter the limiting groove 321 in a direction perpendicular to the first direction O.

[0092] In some embodiments, the elastic member is used to allow at least a portion of the limiting portion 342 to be located within the limiting groove 321, and to generate elastic deformation in a direction perpendicular to the first direction O when the connector 320 pushes the limiting portion 342 open, so as to feed a portion of the limiting member 340 into the limiting groove 321.

[0093] In some embodiments, the limiting member 340 has a guide surface so that, after being connected to the connector 320 along the first direction O, it can move in a direction perpendicular to the first direction O away from the connector 320.

[0094] Specifically, when the limiting part 342 is located in the limiting groove 321 and contacts the groove wall of the limiting groove 321 along the first direction O, if the component of the force exerted by the connecting member 320 on the limiting part 342 along the first direction O in the direction perpendicular to the first direction O is greater than the force exerted by the elastic part 341 on the limiting part 342, then the limiting member 340 releases the limiting of the connecting member 320, and the connecting member 320 can continue to move along the first direction O, and the door 200 continues to rotate; if the component of the force exerted by the connecting member 320 on the limiting part 342 along the first direction O in the direction perpendicular to the first direction O is less than or equal to the force exerted by the elastic part 341 on the limiting part 342, then the limiting member 340 limits the connecting member 320, and the connecting member 320 cannot move along the first direction O, and the door 200 remains suspended.

[0095] In the above embodiment, by providing the elastic part 341, the limiting part 342 can move away from the connector 320 in a direction perpendicular to the first direction O after contacting the connector 320, thereby releasing the limiting of the connector 320, and also allowing the limiting part 342 to enter the limiting groove 321, thereby limiting the connector 320.

[0096] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 6 The guide member 310 has a guide groove 311 on the side facing the support member 400. The guide groove 311 extends along the first direction O. The connector 320 is disposed in the guide groove 311, and the limiting groove 321 communicates with the guide groove 311. The guide member 310 also has a mounting hole 313, which communicates with the guide groove 311. The limiting member 340 is disposed in the mounting hole 313.

[0097] In some embodiments, the opening of the guide groove 311 faces the vehicle support plane along the height direction Z.

[0098] In some embodiments, the elastic portion 341 passes through the mounting hole 313, and the limiting portion 342 is disposed in the mounting hole 313.

[0099] In some embodiments, the mounting hole 313 is a through hole that passes through the guide member 310 in a direction perpendicular to the first direction O. The limiting member 340 also includes a mounting portion that is embedded in the through hole. One end of the elastic portion 341 away from the limiting portion 342 is connected to the mounting portion so as to indirectly connect with the guide member 310.

[0100] In the above embodiments, by providing mounting holes 313 to allow a portion of the limiting member 340 to pass through the guide member 310, the influence of the limiting member 340 on the size of the drive assembly 300 can be reduced, allowing the external size of the drive assembly 300 to be smaller and reducing the space occupied by the drive assembly 300.

[0101] In some embodiments, please refer to Figure 6 The guide groove 311 has a first groove wall 312, which is located on the side of the connector 320 away from the support member 400, and the mounting hole 313 is provided in the first groove wall 312.

[0102] Specifically, when the limiting member 340 limits the connecting member 320, it is located on the side of the connecting member 320 away from the vehicle support plane.

[0103] In the above embodiment, the limiting member 340 connected to the first groove wall 312 can further reduce the size of the drive assembly 300 in the width direction Y of the vehicle body 100, thereby making the size of the vehicle body 100 in the width direction Y larger, and thus making the vehicle body 100 stronger and the vehicle performance better.

[0104] In some embodiments, please refer to Figure 7 , Figure 8 and Figure 9 The driver 330 is disposed in the guide groove 311 and is connected to the guide member 310.

[0105] In the above embodiments, the guide 310, which prevents the drive 330 from being moved, also functions as a housing for the drive assembly 300, making the drive assembly 300 more compact and facilitating its transport. Furthermore, when installing the drive assembly 300 to the door 200, only the guide 310 needs to be connected to the door 200 to achieve a complete connection between the drive assembly 300 and the door 200, reducing the difficulty of vehicle assembly.

[0106] In some embodiments, please refer to Figure 11 The door 200 can rotate relative to the body 100 around the rotation axis 210; when the door 200 is opened, the connecting piece 320 moves in the straight line where the rotation axis 210 is located.

[0107] Specifically, the support member 400 includes a first connecting end 410 and a second connecting end 420 spaced apart. The first connecting end 410 is rotatably connected to the drive assembly 300, and the second connecting end 420 is rotatably connected to the vehicle body 100. Along the width direction Y of the vehicle body 100, the straight line where the rotation axis 210 is located has a first orthographic projection 211 in the longitudinal symmetry plane of the vehicle body 100. The first connecting end 410 has a fourth orthographic projection 430 in the longitudinal symmetry plane of the vehicle, and the second connecting end 420 has a fifth orthographic projection 440 in the symmetry plane of the vehicle. The fourth orthographic projection 430 is located on the side of the fifth orthographic projection 440 that is away from the first orthographic projection 211.

[0108] Specifically, the connector 320 has a first position and a second position. During the process of the door 200 rotating from closed to open, the connector 320 moves along the first direction O close to the line where the rotation axis 210 is located to move from the first position to the second position. Figure 7 The connecting member 320 is located in the first position; during the process of the door 200 opening to closing, the connecting member 320 moves along the first direction O away from the rotation axis 210 to move from the second position to the first position. Figure 9 The connector 320 is located in the second position.

[0109] In the above embodiment, the second connecting end 420 of the support member 400 is closer to the side where the body 100 is connected to the door 200 in the length direction X of the body 100, and when the door 200 is opened, the first connecting end 410 of the support member 400 is closer to the side where the door 200 is connected to the hinge, thereby making the support member 400 closer to the connection between the body 100 and the door 200, thereby reducing the possibility of collision between the support member 400 and the person entering or leaving the vehicle when the door 200 is opened, and improving the comfort of vehicle use.

[0110] In some embodiments, the vehicle body 100 is provided with a sill 120, one end of the support member 400 is rotatably connected to the sill 120, and the drive assembly 300 is connected to the side of the door 200 near the vehicle body 100.

[0111] In some embodiments, the support 400 is connected to the side of the sill 120 away from the roof.

[0112] In the above embodiment, the support member 400 connected to the sill 120 allows the connection hole 121 to be formed in the sill 120, further reducing the impact of the connection hole 121 on the vehicle body 100. At the same time, the relatively flat sill 120 also allows the support member 400 to have a larger range of motion without interfering with the door 200, thereby allowing the door 200 to obtain a larger opening angle.

[0113] The technical solutions provided in the embodiments of this application will be described below with reference to specific examples.

[0114] Example 1

[0115] The vehicle includes a body 100, a door 200, a drive assembly 300, and a support member 400. The door 200 is rotatably connected to the body 100, and the door 200 and the body 100 are spaced apart along the width direction Y of the body 100. The drive assembly 300 is connected to the side of the door 200 near the body 100. One end of the support member 400 is rotatably connected to the drive assembly 300, and the other end of the support member 400 is rotatably connected to the body 100. The support member 400 can rotate relative to the body 100 to rotate the door 200.

[0116] A drive assembly 300 and a support member 400 for driving the opening and closing of the door 200 are disposed between the door 200 and the body 100. The drive assembly 300, which outputs power, is connected to the door 200. Both ends of the support member 400 are connected to the drive assembly 300 and the body 100, respectively, and both ends of the support member 400 can rotate relative to the drive assembly 300 and the body 100. In this way, the end of the support member 400 connected to the body 100 can be positioned as far away from the straight line of the door 200's rotation axis 210 as possible, thereby obtaining a larger lever arm and being able to output greater torque to the door 200. Especially in door opening methods requiring greater driving force, such as when the vehicle adopts a pillarless double-door design, the support member 400 connected to the body 100 can output greater torque to cooperate with other transmission devices, enabling the door 200 to perform more complex opening actions. Connecting the drive assembly 300 to the door 200 avoids the need to create a hole in the body 100 to prevent the drive assembly 300 from being installed. Only a hole needs to be created for connecting the support member 400, which allows for a smaller area of ​​holes in the body 100 and helps to ensure the structural strength of the body 100.

[0117] Example 2

[0118] The support member 400 is connected to one side of the vehicle body 100 along the height direction Z, and the drive component 300 is connected to the side of the support member 400 close to the vehicle body 100 along the height direction Z.

[0119] The support member 400 is connected to the vehicle body 100 and the drive assembly 300 on one side along the height direction Z of the vehicle body 100, so that in the width direction Y of the vehicle body 100, no space needs to be reserved between the drive assembly 300 and the vehicle body 100 for placing the support member 400. This allows for a smaller space between the vehicle body 100 and the drive assembly 300 in the width direction Y of the vehicle body 100, thereby allowing the vehicle body 100 to have a larger dimension in the width direction Y of the vehicle body 100, which is beneficial to ensuring the structural strength of the vehicle body 100.

[0120] Example 3

[0121] The drive assembly 300 includes a guide 310, a connector 320, and a driver 330. The guide 310 is connected to the door 200; the connector 320 is connected to the guide 310 and rotatably connected to the support 400; the driver 330 is connected to the connector 320 and can drive the connector 320 to move along a first direction O. The driver 330 includes a transmission part 331 and a drive part 332. The transmission part 331 passes through the connector 320, and the guide 310 can restrict the rotation of the connector 320; the drive part 332 is connected to one end of the transmission part 331 and can rotate the transmission part 331 to drive the connector 320 to move along the first direction O.

[0122] The drive mechanism, in which the transmission unit 331 rotates to move the connecting member 320, thereby causing the support member 400 to rotate, allows the drive assembly 300 to withstand a greater load, thus allowing the door 200 connected to the drive assembly 300 to have a greater mass. Simultaneously, this drive mechanism provides smoother operation, resulting in smoother opening and closing of the door 200 and a better user experience.

[0123] Example 4

[0124] The door 200 is able to rotate relative to the body 100 around the rotation axis 210; along the width direction Y of the body 100, the straight line where the rotation axis 210 is located has a first orthographic projection 211 in the longitudinal symmetry plane of the body 100; the transmission unit 331 has a second orthographic projection 333 in the longitudinal symmetry plane of the body 100, and the drive unit 332 has a third orthographic projection 334 in the longitudinal symmetry plane of the body 100, and the third orthographic projection 334 is located on the side of the second orthographic projection 333 away from the first orthographic projection 211.

[0125] By positioning the transmission part 331, which is connected to the connector 320, closer to the drive part 332 on the side of the line where the rotation shaft 210 is located, the support member 400, which is connected to the connector 320, can be positioned closer to the line where the rotation shaft 210 is located, reducing the possibility of people tripping over the support member 400 when the vehicle is started. At the same time, it also allows for a shorter length of the support member 400, resulting in better mechanical performance.

[0126] The opening process of car door 200 is as follows:

[0127] Please see Figure 7 The drive assembly 300 drives one end of the support member 400 to move along the first direction O close to the rotation axis 210 of the door 200, so that the support member 400 rotates counterclockwise, and the door 200 rotates counterclockwise and opens under the drive of the support member 400.

[0128] The closing process of car door 200 is as follows:

[0129] Please see Figure 9The drive assembly 300 drives one end of the support member 400 to move along a first direction O away from the rotation axis 210 of the door 200, so that the support member 400 rotates clockwise, and the door 200 rotates clockwise and closes under the drive of the support member 400.
