[0038] Through the above technical solution, in the door swing mechanism provided by the present disclosure, the movement trajectory of the door relative to the vehicle body 100 can be controlled by the first guide portion 24 of the first link assembly 2, so that the door 200 can be opened and closed.

[0039] refer to Figure 3 and Figure 4 As shown, the first guide portion 24 may be disposed at an end of the first link assembly 2 close to the vehicle body 100 .

[0040] Specifically, the first guide portion 24 can be configured as a slide groove, and the first link assembly 2 can also include a protrusion 25, which can cooperate with the first guide portion 24, that is, the protrusion 25 can slide in the first guide portion 24, so that the door 200 has a closed position swung forward and embedded in the vehicle body 100 and an open position moved out of the vehicle body 100 and swung backward.

[0041] In order to facilitate the arrangement of the first guide portion 24 and the protrusion 25, refer to Figure 3 and Figure 4 As shown, the first link assembly 2 may include a first body bracket 21, a first door bracket 22, and a horizontally extending first link 20. The first body bracket 21 may be fixedly connected to the inner side of the body 100, and the first link 20 may be hinged to the first body bracket 21 through a vertically extending third shaft 23, thereby realizing relative rotation with the body 100; the first door bracket 22 may be fixedly connected to the inner side of the door 200, and the first link 20 may be hinged to the first door bracket 22 through a vertically extending fourth shaft 26, thereby realizing relative rotation with the door 200; the first guide portion 24 may be disposed on the first body bracket 21, and may extend horizontally above and / or below the first link 20, and the protrusion 25 may be fixedly connected to the first link 20, and may be slidably connected to the first guide portion 24, so as to guide the moving trajectory of the door 200 through relative sliding between the first guide portion 24 and the protrusion 25.

[0042] In addition, in order to make the movement process of the vehicle door 200 smooth, the vehicle door swing mechanism may further include a second link assembly 1, and the second link assembly 1 may be spaced apart from the first link assembly 2 in the vertical direction.

[0043] Among them, the second link assembly 1 may include a horizontally extending second link 10, which is used to be hinged between the inner side of the vehicle body 100 and the inner side of the door 200, and can rotate in a horizontal plane to form a stable spatial four-bar mechanism together with the second link 10, the vehicle body 100 and the door 200.

[0044] In the specific embodiments of the present disclosure, reference is made to Figures 1 to 3 As shown, the second connecting rod assembly 1 can be arranged above the first connecting rod assembly 2.

[0045] refer to Figure 3 and Figure 4 As shown, in order to facilitate the hinge connection between the second link 10 and the vehicle body 100 and the vehicle door 200, the second link assembly 1 may further include a second vehicle body bracket 11 and a second vehicle door bracket 12. The second vehicle body bracket 11 may be fixedly connected to the inner side of the vehicle body 100, and the second link 10 may be hinged to the second vehicle body bracket 11 through a vertically extending first rotating shaft 13, thereby realizing the relative rotation between the second link 10 and the vehicle body 100; the second vehicle door bracket 12 may be fixedly connected to the inner side of the vehicle door 200, and the second link 10 may be hinged to the second vehicle door bracket 12 through a vertically extending second rotating shaft 14, thereby realizing the relative rotation between the second link 10 and the vehicle door 200.

[0046] In order to drive the movement of the vehicle door 200 , the vehicle door swing mechanism may further include a driving module (not shown), which is used to drive the second connecting rod 10 to rotate in a horizontal plane so that the second connecting rod 10 can drive the vehicle door 200 to swing forward and backward.

[0047] The driving module may include a driving motor (not shown), and the driving motor may be disposed between the second vehicle body bracket 11 and the second connecting rod 10 to drive the second connecting rod 10 to rotate around the first rotating shaft 13 .

[0048] Through the above technical solution, the first connecting rod assembly 2 and the second connecting rod assembly 1 are both arranged on the inner side of the vehicle door 200. The space they occupy on the inner side of the vehicle door 200 is small, the structure is simple, and the shape layout on the inner panel of the vehicle door is not affected.

[0049] In order to enable the sliding connection between the first guide portion 24 and the protrusion 25 to guide the vehicle door 200 to swing between the open position and the closed position, the vehicle door swing mechanism can be configured as follows: when the protrusion 25 slides from front to rear in the first guide portion 24, the vehicle door 200 can move from the above-mentioned closed position to the above-mentioned open position; when the protrusion 25 slides from rear to front in the first guide portion 24, the vehicle door 200 can move from the above-mentioned open position to the above-mentioned closed position.

[0050] That is, when the second link 10 drives the door 200 to swing forward under the drive of the driving module, the protrusion 25 can slide from rear to front in the first guide portion 24 to control the door 200 to swing forward and embed into the vehicle body 100; when the second link 10 drives the door 200 to swing backward under the drive of the driving module, the protrusion 25 can slide from front to rear in the first guide portion 24 to control the door 200 to move out of the vehicle body and swing backward.

[0051] In order to make the vehicle door 200 have a moving trajectory of swinging forward and being embedded in the vehicle body 100 or moving outward from the vehicle body 100 and swinging backward, refer to Figure 4 As shown, the first guide portion 24 may include an arc segment 241 surrounding the third rotating shaft 23, that is, the center of the arc segment 241 is located on the central axis of the third rotating shaft 23, the arc segment 241 may extend from front to rear and protrude toward the outside of the vehicle, and the arc segment 241 may be configured such that: when the protrusion 25 slides from front to rear in the arc segment 241, the door 200 may first move outward from the vehicle body 100 and then swing backward; when the protrusion 25 slides from rear to front in the arc segment 241, the door 200 may first swing forward and then embed into the vehicle body 100. Through the arc segment 241, the door 200 may first be pushed outward from the vehicle and then fit toward the vehicle body 100 during the movement, so that the door 200 may be embedded in the vehicle body 100 in the closed position and may also fit toward the vehicle body 100 in the open position, so as to reduce the width of the vehicle when the door is opened, and facilitate passengers to get on and off the vehicle.

[0052] refer to Figure 5 As shown, in the related art, in order to ensure good sealing between the front door 300 and the rear door, the front edge of the rear door is usually overlapped with the rear edge of the front door 300, that is, a gap is usually formed between the rear edge of the front door 300 and the B-pillar 400 for the front edge of the rear door to be inserted, so as to achieve overlapping of the front door 300 and the rear door.

[0053] When the door swing mechanism provided by the present disclosure is used for the rear door, in order to enable the front edge of the door 200 to smoothly enter and exit the gap, refer to Figure 4As shown, the first guide portion 24 may further include a straight segment 242 connected to the front end of the arc segment 241, the straight segment 242 extending obliquely from front to rear toward the outside of the vehicle, and the rear end of the straight segment 242 is connected to the front end of the arc segment 241, and the straight segment 242 may be configured as follows: when the protrusion 25 slides from front to rear in the straight segment 242, the door 200 can be tilted outwardly at a certain angle relative to the vehicle body 100, so that the rear edge of the door 200 is first lifted from the vehicle body 100, and the front edge can be obliquely cut out from the gap between the front door 300 and the B-pillar 400; when the protrusion 25 slides from rear to front in the straight segment 242, the door 200 can be tilted outwardly at a certain angle relative to the vehicle body 100, and the front edge of the door 200 can be embedded in the vehicle body 100 before the rear edge and obliquely cut into the gap.

[0054] In order to enable the door 200 to return to be parallel to the vehicle body 100 when the protrusion 25 moves to the front end of the straight section 242, Figure 5 As shown, a guide buckle 32 may be provided on the B-pillar 400, a guide block 31 may be provided on the vehicle door 200, and a guide groove 311 with an opening toward the front may be provided on the guide block 31. When the protrusion 25 slides from rear to front in the straight section 242, the guide buckle 32 can slide into the guide groove 311. Under the action of the guide groove 311, the vehicle door 200 can return to be roughly parallel to the vehicle body 100, so that the rear edge of the vehicle door 200 can also be embedded in the vehicle body 100, thereby allowing the vehicle door 200 as a whole to be embedded in the vehicle body 100.

[0055] Since the distance between the protrusion 25 and the third shaft 23 changes when sliding in the straight section 242, the length of the portion between the position where the protrusion 25 is connected on the first connecting rod 20 and the third shaft 23 changes. Figure 3 and Figure 4 As shown, the first connecting rod 20 may include a first rod segment 201 and a second rod segment 202. The first rod segment 201 may be hinged to the first vehicle body bracket 21 via a third rotating shaft 23, and the second rod segment 202 may be hinged to the first door bracket 22 via a fourth rotating shaft 26, thereby realizing hinge connection with the vehicle door 200. The protrusion 25 may be fixedly connected to the second rod segment 202. The first connecting rod assembly 20 may further include a second guiding portion to guide the second rod segment 202 to move relative to the first rod segment 201 along the length direction of the first rod segment 201 to adapt to the change in the distance between the protrusion 25 and the third rotating shaft 23, thereby avoiding the first connecting rod assembly 2 from getting stuck.

[0056] In a specific embodiment of the present disclosure, the second guide portion may be configured as a guide groove extending along the length direction of the first rod segment 201, and the second guide portion may be provided at one of the first rod segment 201 and the second rod segment 202, and the other of the first rod segment 201 and the second rod segment 202 is inserted into the second guide portion. Figure 3 and Figure 4 In the illustrated embodiment, a guide groove is provided in the first rod segment 201 , and the second rod segment 202 is inserted into the guide groove. As the protrusion 25 slides in the straight segment 242 , the second rod segment 202 can slide in the first rod segment 201 along the length direction of the first rod segment 201 .

[0057] In order to ensure the stability of the vehicle door 200 during movement, an elastic member (not shown) can be connected between the second rod segment 202 and the first body bracket 21, and the elastic member can provide elastic force for the second rod segment 202 to move toward the first body bracket 21, thereby eliminating the shaking of the vehicle door 200 caused by the installation gap.

[0058] Based on the above technical solution, the present disclosure also provides a vehicle door assembly, referring to Figures 1 to 3 As shown, the door assembly may include a vehicle body 100, a door 200 and the door swing mechanism in the above technical solution, which enables the door 200 to have a closed position of swinging forward and embedding into the vehicle body 100 and an open position of moving out of the vehicle body 100 and swinging backward.

[0059] Through the above technical solution, the vehicle door assembly provided by the present disclosure has the same technical effect as the vehicle door swing mechanism in the above technical solution, and in order to avoid unnecessary repetition, it will not be described here.
