DETAILED DESCRIPTION

[0049] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0050] In the present disclosure, the orientation words such as "inner" and "outer" are used in the sense of "inner" and "outer" with respect to the outline of the corresponding component itself, unless otherwise stated. The "rotation side" of the first door body and the "rotation side" of the second door body refer to the side of the two door bodies connected to the vehicle body, and the "opening side" of the first door body and the "opening side" of the second door body refer to the side opposite to the rotation side of each door body in the first direction, i.e. the side on which the first door body and the second door body cooperate with each other. In addition, the terms "first", "second", "third" and the like used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance. Furthermore, in the following description, the same reference numerals in different drawings represent the same or similar elements, unless otherwise explained. The above definitions are only used to explain and illustrate the present disclosure, and should not be understood as limiting the present disclosure.

[0051] The split door vehicle, the lock catch assembly and the hinge assembly in the exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings. Reference is made to Figures 1 to 20As shown, the first aspect of the present disclosure provides a split door vehicle, comprising a vehicle body 1, a first door body 2, a second door body 3, a lock catch assembly 4 and a hinge assembly 5, wherein the rotating side of the first door body 2 is hinged to the vehicle body 1; the rotating side of the second door body 3 is hinged to the vehicle body 1, and the opening side of the second door body 3 is used to overlap with the opening side of the first door body 2; the lock catch assembly 4 is arranged on the vehicle body 1 and can move along the first direction A between the first position and the second position, and keep the opening side of the second door body 3 locked with the lock catch assembly 4 during the movement between the first position and the second position; the hinge assembly 5 is arranged on the vehicle body 1, and the hinge assembly 5 is connected with the rotating side of the second door body 3, so that the rotating side of the second door body 3 can move away from or close to the vehicle body along the first trajectory, and the opening side of the second door body 3 can rotate to open or close along the second trajectory.

[0052] Through the above technical solution, for example, the first door body 2 can be the front door of the vehicle, the second door body 3 can be the rear door of the vehicle, and the overlapping area of the two door bodies in the inside-outside direction of the vehicle when overlapping can form a first overlapping area 21 on the first door body 2 and a second overlapping area 31, and the second overlapping area 31 is located on the inside of the first overlapping area 21. A sealing structure 10 such as a sealing strip can be arranged between the first overlapping area 21 and the second overlapping area 31 to realize the sealing cooperation of the two, specifically, the cross section of the first overlapping area 21 in the first direction A can be arranged in a stepped shape, and correspondingly, the cross section of the second overlapping area 31 in the first direction A can also be arranged in a stepped shape, so that the first door body 2 and the second door body 3 can be connected more closely.

[0053] Wherein, when the opening side of the second door body 3 is locked with the lock catch assembly 4 and is in the first position, the first door body 2 and the second door body 3 can be in a sealing cooperation state, and when the opening side of the second door body 3 is locked with the lock catch assembly 4 and is in the second position, the opening of the second door body 3 will not interfere with the first door body 2.

[0054] When the second door body 3 is opened, the rotating side of the second door body 3 can first move away from the vehicle body 1 along the first track, and at the same time, the opening side of the second door body 3 moves between the first position and the second position through the locking assembly 4 to avoid interference between the second door body 3 and the first door body 2 in the subsequent opening process. When the opening side of the second door body 3 moves to a position that does not interfere with the first door body 2 during opening, for example, the second position, the opening side of the second door body 3 can move away from the vehicle body along the second track, thereby opening the second door body 3. Correspondingly, when the second door body 3 is closed, the opening side of the second door body 3 needs to first move towards the vehicle body along the second track and be locked with the vehicle body 1, and then when the rotating side of the second door body 3 moves towards the vehicle body along the first track, the opening side of the second door body 3 moves between the first position and the second position, until it is sealed with the first door body 2, thereby completing the closing of the second door body 3. Based on this, the door bodies of the double-opening door vehicle in the present disclosure will not interfere with each other during opening, thereby realizing the disordered opening of the double-opening door vehicle and improving the user experience.

[0055] In the embodiments of the present disclosure, as shown in Figures 1 to 4 、 Figure 16 and Figure 17 , during the process in which the rotating side of the second door body 3 moves away from the vehicle body along the first track, the opening side of the second door body 3 moves from the first position to the second position; and during the process in which the rotating side of the second door body 3 moves towards the vehicle body 1 along the first track, the opening side of the second door body 3 moves from the second position to the first position.

[0056] For example, when the second door body 3 needs to be opened, the rotating side of the second door body 3 will first move away from the vehicle body along the first track, and at the same time, the opening side of the second door body 3 moves from the first position to the second position through the locking assembly 4, that is, moves in the direction away from the first door body 2. After the opening side of the second door body 3 is in the second position, the opening side of the second door body 3 can be unlocked with the locking assembly 4, and then the opening side of the second door body 3 can rotate along the second track to move away from the vehicle body, thereby realizing the opening of the second door body 3. Similarly, when the second door body 3 needs to be closed, the opening side of the second door body 3 needs to first move towards the vehicle body 1 along the second track to be attached to the vehicle body 1 and be locked with the vehicle body 1 through the locking assembly 4. At this time, the opening side of the second door body 3 is in the second position, and then when the rotating side of the second door body 3 moves towards the vehicle body 1 along the first track, the opening side of the second door body 3 moves from the second position to the first position through the locking assembly 4, that is, moves in the direction towards the first door body 2. After the opening side of the second door body 3 moves to the first position, the rotating side of the second door body 3 is also attached to the vehicle body 1, thereby realizing the closing of the second door body 3.

[0057] In the embodiments of the present disclosure, as shown in Figures 6 to 17As shown, the lock assembly 4 can include a guide structure 41 provided on the vehicle body 1 and a lock structure 42 unlockably connected with the lock body of the second door body 3, the lock structure 42 being slidably connected with the guide structure 41 along the first direction A to move between the first position and the second position and to keep locked with the opening side of the second door body 3 during the movement between the first position and the second position. The opening side of the second door body 3 can slide between the first position and the second position through the lock structure 42, so that the second door body 3 is away from and avoids the first door body 2 when being opened and is close to and sealingly connected with the first door body 2 when being closed.

[0058] The distance between the first position and the second position can be 20mm-50mm.

[0059] In addition, as shown in Figure 18 As shown, the hinge assembly 5 can include a first hinge part 51 connected with the second door body, a second hinge part 52 connected with the vehicle body and a connecting arm 53 connecting the first hinge part 51 and the second hinge part 52, the rotating side of the second door body 3 can rotate by a first angle around the second hinge part 52 to move away from or close to the vehicle body 1 along a first trajectory, and the opening side of the second door body 3 can rotate by a second angle around the second hinge part 52 to open or close along a second trajectory. When the second door body 3 is opened, the rotating side of the second door body 3 will first rotate by the first angle around the second hinge part 52, and the trajectory forms the first trajectory, and in order to ensure that the rotating side of the second door body 3 can smoothly rotate by the first angle, the rotating side of the second door body 3 and the first hinge part 51 will also rotate relative to each other, and then the opening side of the second door body 3, the first hinge part 51 and the connecting arm 53 will jointly rotate by the second angle around the second hinge part 52, and the rotating trajectory forms the second trajectory; correspondingly, when the second door body 3 is closed, the opening side of the second door body 3 will first reversely rotate by the second angle to make the opening side of the second door body 3 fit with the vehicle body 1, and then the rotating side of the second door body 3 reversely rotates by the first angle to fit with the vehicle body 1, so as to realize the closing of the second door body 3. In order to prevent the relative movement between the first hinge part 51 and the rotating side of the second door body 3 when the second door body 3 is opened along the second trajectory, a limiting structure (not shown in the figure) can be provided on the first hinge part 51 to limit the movement between the first hinge part 51 and the rotating side of the second door body 3.

[0060] Specifically, as shown in Figure 18 The first hinge part 51 can include a first hinge seat 511 connected with the second door body 3 and a first rotating shaft 512 rotatably connected with the first hinge seat 511; and the second hinge part 52 can include a second hinge seat 521 connected with the vehicle body 1 and a second rotating shaft 522 rotatably connected with the second hinge seat 521.

[0061] When the second door 3 is opened, the rotating side of the second door 3 rotates by a first angle around the second rotating shaft 522 to move away from the vehicle body 1 along a first trajectory, and at the same time, the first hinge seat 511 rotates relative to the first rotating shaft 512, and the opening side of the second door 3 moves from the first position to the second position.

[0062] When the second door 3 is closed, the rotating side of the second door 3 rotates by a first angle around the second rotating shaft 522 to move close to the vehicle body 1 along a first trajectory, and at the same time, the first hinge seat 511 rotates relative to the first rotating shaft 512, and the opening side of the second door 3 moves from the second position to the first position.

[0063] When the second door 3 is closed, the rotating side of the second door 3 rotates by a first angle around the second rotating shaft 522 to move close to the vehicle body 1 along a first trajectory, and at the same time, the first hinge seat 511 rotates relative to the first rotating shaft 512, and the opening side of the second door 3 moves from the second position to the first position.

[0064] In addition, in order to ensure the stability of the second door 3 in the closed state, that is, to prevent the second door from being separated from the vehicle body when it is not necessary to open, the opening vehicle can further include a second lock assembly 6 arranged on the vehicle body 1, and the rotating side of the second door 3 is unlockedly connected to the second lock assembly 6, and the second lock assembly 6 is used to unlock before the second door 3 is separated from the vehicle body along the first trajectory.

[0065] It should be noted that the connection mode of the first door 2 and the vehicle body 1 is a conventional arrangement mode. For example, the first door 2 and the vehicle body 1 can be hinged through a second hinge assembly 8, and locked with the vehicle body 1 through a third lock assembly 12. The second hinge assembly 8 can include a first hinge 81 and a second hinge 82. One end of the first hinge 81 can be connected to the rotating side of the first door 2 through a fastener such as a bolt or a screw. One end of the second hinge 82 can be connected to the vehicle body 1 through a fastener such as a bolt or a screw. The other end of the first hinge 81 and the other end of the second hinge 82 are rotationally connected through a connecting shaft 83. During the opening or closing process of the first door 2, the first hinge will rotate around the connecting shaft 83 to achieve the opening or closing of the first door 2.

[0066] In addition, as shown in Figure 1 The opening vehicle can further include a length-adjustable balance bar 9. One end of the balance bar 9 can be hinged to the vehicle body 1, and the other end can be hinged to the bottom of the second door 3. The balance bar 9 can be configured as a gas cylinder structure, so that the balance bar 9 can assist the stability of the second door 3 during the opening or closing process of the second door 3, so that the opening and closing process of the second door 3 is more smooth.

[0067] The second aspect of this disclosure, such as Figures 6 to 17 As shown, a latch assembly is provided that can be applied to the aforementioned double-door vehicle, or to a double-door vehicle with other structures. The latch assembly may include a guide structure 41 and a latch structure 42. The guide structure 41 is mounted on at least one side of the vehicle body in a second direction B. The latch structure 42 is slidably connected to the guide structure 41 along a first direction A. The latch structure 42 includes a latch body 421, which is used to unclampably engage with the lock body on the opening side of the second door 3, so that the opening side of the second door 3 can move in a first position and a second position.

[0068] The first position is the position where the opening side of the second door 3 is sealed to the first door 2, and the second position is the position where the opening side of the second door 3 will not interfere with the first door 2 when the second door 3 is opened.

[0069] After the latch body 421 of the latch structure 42 is connected to the guide structure 41, it can position the opening side of the second door 3 in either the first or second position as needed. When the second door 3 needs to be closed, the user can push the second door 3 with external force, or the latch body 421 can be actively or passively driven by an electric drive component such as a motor to move the opening side of the second door 3 from the second position to the first position. When the second door 3 moves to the first position, it can be sealed with the first door 2, thereby completing the closing and sealing operation of the second door 3. Correspondingly, when the second door 3 needs to be closed... When the second door is opened, the user can push the second door body with external force or drive the latch body 421 actively or passively by an electric drive component such as a motor to move the opening side of the second door body from the first position to the second position. After the second door body 3 moves to the second position, it can unlock with the latch body 421 and open under the action of the hinge assembly 5, thus completing the opening of the second door body 3. In addition, the guide structure 41 is installed on at least one side of the second direction B of the vehicle body 1, which can also ensure the stability of the opening side of the second door body 3 when it moves in the first direction A and when the second door body 3 is closed.

[0070] Based on this, the latch assembly of this disclosure enables vehicles with double doors to open and close their doors in an unordered manner without the need for a B-pillar. Thus, the latch assembly of this disclosure can increase the space for pedestrians to pass through while ensuring the sealing and stability of the doors of vehicles with double doors.

[0071] In embodiments of this disclosure, such as Figures 6 to 17As shown, the guide structure 41 may include a guide body 411 and a first guide portion 412 disposed on the guide body 411. The guide body 411 is used to connect with the vehicle body. The latching structure 42 may include a latching base plate 422. The latching body 421 is disposed on the side of the latching base plate 422 away from the guide structure 41, and a connecting portion 423 is disposed on the side of the latching base plate 422 facing the guide structure 41. The latching base plate 422 is slidably connected to the first guide portion 412 through the connecting portion 423. That is, the connecting portion 423 and the latching body 421 are disposed on opposite sides of the latching base plate 422. After the opening side of the second door 3 is locked with the latching body 421, the latching base plate 422 can slide on the first guide portion 412 of the guide body 411 through the connecting portion 423 toward a first position or a second position, thereby ensuring that the opening side of the second door 3 can move smoothly to the first position or the second position.

[0072] Among them, such as Figures 6 to 12 As shown, the guide body 411 has a boss structure 413 protruding in a third direction C, and a first guide portion 412 is disposed on the boss structure 413. The connecting portion 423 includes a connector 4231 and a substrate recess 4232 extending toward the first guide portion 412. One end of the connector 4231 is connected to the inner wall of the substrate recess 4232, and the other end passes through the first guide portion 412 and abuts against the inner wall of the boss structure 413. The boss structure 413 and the substrate recess 4232 are respectively extended and protruded toward each other. On the one hand, this facilitates the connection between the substrate 422 and the guide body 411. On the other hand, the boss structure 413 can also ensure its own strength and rigidity, and improve the stability after the two are connected.

[0073] Alternatively, the connector 4231 can be configured as a sliding rivet. One end of the sliding rivet abuts against the inner wall of the substrate recess 4232, and the other end abuts against the inner wall of the boss structure 413 after passing through the first guide portion 412. This allows the substrate recess 4232 to move within the first guide portion 412 while simultaneously connecting the substrate recess 4232 and the boss structure 413. Furthermore, using a sliding rivet as the connector 4231 facilitates the connection between the substrate recess 4232 and the boss structure 413 and also saves costs.

[0074] The inner wall of the substrate recess 4232 faces the latch body 421, and the inner wall of the boss structure 413 faces away from the latch body 421. The connector 4231 can also be a pin or a connecting rod, as long as it can ensure that the substrate recess 4232 can move along the first guide portion 412 while connecting the boss structure 413 and the substrate recess 4232.

[0075] In some implementations, such as Figure 6 , Figure 7 ,Figure 10 , Figure 11 As shown, the guide body 411 has mounting holes 7 on both sides of the boss structure 413 in the first direction A for connecting with the vehicle body 1. That is, the guide body 411 has multiple mounting holes 7. Increasing the number of mounting holes 7 can improve the stability of the guide body 411 after connecting with the vehicle body 1. In addition, the mounting holes 7 are located on both sides of the boss structure 413 in the first direction A, so that the mounting holes 7 can be distributed as evenly as possible on the guide body 411, avoiding stress concentration after connecting with the vehicle body 1 due to concentrated mounting holes in the same area, thus ensuring the connection effect.

[0076] In embodiments of this disclosure, such as Figures 10 to 12 As shown, the first guide portion 412 can be configured as an open structure extending along the first direction A, that is, the locking base plate 422 can slide on the guide body 411 through the open structure under the action of the connector 4231. In addition, the structure of the open structure is simpler than that of guide components such as guide rails, and the cooperation between the open structure and the connector 4231 can also provide a certain limiting effect on the movement of the locking structure 42 in the first direction A, preventing the locking structure 42 from dislodging from the guide structure 41.

[0077] In some embodiments not shown, the first guide portion 412 may also be configured as a guide rail or a groove structure. In this case, the connector 4231 may be configured as a slider, that is, the locking base plate 422 may slide on the guide rail or groove structure of the guide body 411 by the slider.

[0078] In some implementations, such as Figures 6 to 17 As shown, the guide structure 41 may further include a second guide portion 414, which is disposed at at least one end of the guide body 411 in the second direction B. The locking structure 42 includes a guide engagement portion 424, which engages with the second guide portion 414. The second guide portion 414 is used to restrict the movement of the locking structure 42 in the second direction B and / or the third direction C. While the first guide portion 412 allows the locking structure 42 to move on the guide body 411 in the first direction A, the guide engagement portion 424, after engaging with the second guide portion 414, enables the second guide portion 414 to limit the locking base plate 422 in the second direction B and / or the third direction C, thereby ensuring the stability of the locking structure 42 when sliding on the guide structure 41.

[0079] Among them, such as Figures 6 to 17As shown, the second guide portion 414 can include a C-shaped slot 4141 opening towards the opposite end of the guide body 411 in the second direction B; the guide matching portion 424 can include a pulley set 425 capable of abutting the inner wall of the C-shaped slot 4141 in the second direction B or the third direction C. That is, the locking base plate 422 can roll in the C-shaped slot 4141 through the pulley set 425, so as to move the locking base plate 422 along the first guide portion 412, and in addition, the pulley set 425 can abut different inner wall surfaces in the C-shaped slot 4141 while rolling in the C-shaped slot 4141, so that the C-shaped slot 4141 can limit the movement of the locking structure 42 in the second direction B and / or the third direction C, thereby the second guide portion 414 can assist the locking base plate 422 to move on the guide body 411 through the first guide portion 412, so as to ensure the stability of the locking structure 42 during movement.

[0080] Specifically, as shown, Figures 1 to 13 The C-shaped slot 4141 can include first limiting surfaces 4142 oppositely arranged in the third direction C and a second limiting surface 4143 located between the two first limiting surfaces 4142; the pulley set 425 includes at least one pulley body 4251; the pulley body 4251 can abut the two first limiting surfaces 4142, so that the first limiting surfaces 4142 can limit the movement of the pulley body 4251 in the third direction C; or the pulley body 4251 can abut the second limiting surface 4143, so that the second limiting surface 4143 can limit the movement of the pulley body 4251 in the second direction B. That is, when the pulley body 4251 is arranged horizontally, the two sides thereof in the third direction C can abut the two first limiting surfaces 4142 in the C-shaped slot 4141, thereby the pulley body 4251 can roll in the C-shaped slot 4141 while being limited by the two first limiting surfaces 4142 in the third direction C, so as to ensure the stability of the locking base plate 422 in the third direction C; or when the pulley body 4251 is arranged vertically, one side thereof in the second direction B can abut the second limiting surface 4143, thereby the pulley body 4251 can roll in the C-shaped slot 4141 while being limited by the second limiting surface 4143 in the second direction B, so as to ensure the stability of the locking base plate 422 in the second direction B.

[0081] In addition, as shown, Figures 13 to 15As shown, the end of the lock base plate 422 in the second direction B is formed with a first mounting area 4221 or a second mounting area 4222 for mounting the pulley body 4251; the first mounting area 4221 is arranged extending from the end of the lock base plate 422 and the extending direction of the first mounting area 4221 is parallel to the second direction B, the pulley body 4251 is connected to the first mounting area 4221 so that the pulley body 4251 can abut against the second limiting surface 4143; the second mounting area 4222 is arranged bending from the end of the lock base plate 422 to the side away from the lock body 421, the pulley body 4251 is connected to the second mounting area 4222 so that the pulley body 4251 can abut against the first limiting surface 4142. The arrangement of the first mounting area 4221 and the second mounting area 4222 can change the angle of the pulley body 4251 without the need to arrange other complex structures on the lock base plate 422, thereby facilitating the abutment of the pulley body 4251 against the first limiting surface 4142 or the second limiting surface 4143 in the C-shaped groove 4141.

[0082] In the embodiments of the present disclosure, as Figures 6 to 17 shown, the second guide part 414 is symmetrically arranged at opposite ends of the guide body 411 in the second direction B. The arrangement of the plurality of second guide parts 414 can correspondingly arrange the guide fitting part 424 at opposite ends of the lock base plate 422 in the second direction B, thereby improving the stability of the lock base plate 422 in the second direction B and / or the third direction C.

[0083] Specifically, as Figures 13 to 15 shown, the first mounting area 4221 can be arranged at one end of the lock base plate 422 in the second direction B, and the second mounting area 4222 is arranged at the other end of the lock base plate 422 in the second direction B. The pulley body 4251 arranged in the first mounting area 4221 can abut against the second limiting surface 4143 of the C-shaped groove 4141 to limit the movement of the lock base plate 422 in the second direction B, and the pulley body 4251 arranged in the second mounting area 4222 can abut against the first limiting surface 4142 of the C-shaped groove 4141 to limit the movement of the lock base plate 422 in the third direction C, that is, the two C-shaped grooves 4141 arranged on the guide body 411 are used to limit the lock base plate 422 in the second direction B and the third direction C, respectively, thereby ensuring the stability of the lock base plate 422 in the second direction B and the third direction C when the lock base plate 422 moves on the guide body 411 through the first guide part 412.

[0084] In some embodiments, as Figures 6 to 17As shown, the lock base plate 422 is provided with a guide matching part 424 on each side of the lock body 421 in the first direction A. The provision of multiple guide matching parts 424 can further ensure the stability of the lock base plate 422 when moving on the guide body 411.

[0085] In addition, it should be noted that the number and arrangement of the pulley sets 425 in the guide matching part 424 can be appropriately adjusted as needed. For example, on the same side of the lock base plate 422 in the second direction B, there can be multiple adjacent pulley sets 425, one or more of the multiple adjacent pulley sets 425 can abut against the first limiting surface 4142 of the C-shaped groove 4141, and the remaining pulley sets 425 can abut against the second limiting surface 4143 of the C-shaped groove 4141; or, all the multiple adjacent pulley sets 425 abut against the first limiting surface 4142 of the C-shaped groove 4141; or, all the multiple adjacent pulley sets 425 abut against the second limiting surface 4143 of the C-shaped groove 4141; of course, each pulley set 425 can be configured as one pulley body 4251 or multiple pulley bodies 4251.

[0086] In some embodiments, as Figures 6 to 17 As shown, the projection of part of the lock base plate 422 in the third direction C covers at least part of the projection of the second guide part 414 in the third direction C. That is, the lock base plate 422 and the second guide part 414 have a certain amount of overlap in the third direction C to ensure the stability of the lock base plate 422 in the third direction C.

[0087] In embodiments of the present disclosure, two lock assemblies 4 can be provided, and the two lock assemblies 4 are respectively arranged on opposite sides of the vehicle body 1 in the second direction B. In this way, the stability of the opening side of the second door body 3 when moving in the first direction A can be further improved.

[0088] In addition, as Figure 18 As shown, a hinge assembly is provided, which includes a first hinge part 51, a second hinge part 52, and a connecting arm 53 connecting the first hinge part 51 and the second hinge part 52; the first hinge part 51 is configured to be connected with the second door body 3, and the second hinge part 52 is connected with the vehicle body 1, so that the rotating side of the second door body 3 can rotate by a first angle about the first pivot axis L during the movement of the opening side of the second door body 3 between the first position and the second position, and after the opening side of the second door body 3 moves to the second position, the opening side of the second door body 3 can rotate by a second angle about the first pivot axis L; wherein the trajectory of the rotating side of the second door body 3 rotating by the first angle about the first pivot axis L forms a first trajectory; and the trajectory of the opening side of the second door body 3 rotating by the second angle about the first pivot axis L forms a second trajectory.

[0089] Exemplarily, when the rotation side of the second door body 3 rotates a first angle to the side away from the vehicle body 1 along the first pivot axis L, the door opening side of the second door body 3 moves from the first position to the second position, and since the door opening side of the second door body 3 is still on the vehicle body 1 at this time, in order to ensure the smoothness of the process, the rotation side of the second door body 3 also rotates relative to the first hinge part 51.

[0090] Specifically, the first hinge part 51 can include a first hinge seat 511 connected to the second door body 3 and a first rotation shaft 512 rotatably connected to the first hinge seat 511; the second hinge part 52 includes a second hinge seat 521 connected to the vehicle body 1 and a second rotation shaft 522 rotatably connected to the second hinge seat 521; when the rotation side of the second door body 3 moves along the first trajectory, the first hinge seat 511 rotates relative to the first rotation shaft 512; when the door opening side of the second door body 3 moves along the second trajectory, the second door body 3, the first hinge part 51 and the connecting arm 53 rotate around the second rotation shaft 522; wherein the axis of the second rotation shaft 522 forms the first pivot axis L.

[0091] Exemplarily, when the second door body 3 is opened, the rotation side of the second door body 3 will first rotate a first angle out of the vehicle body around the axis of the second rotation shaft 522 through the first hinge part 51 and the connecting arm 53, at the same time, the door side of the second door body 3 moves from the first position to the second position, and the first hinge seat 511 on the second door body 3 rotates relative to the first rotation shaft 512 to ensure the smoothness of the process; after the rotation side of the second door body 3 moves to the second position, the door opening side of the second door body 3, the first hinge part 51 and the connecting arm 53 will rotate a second angle out of the vehicle body 1 around the axis of the second rotation shaft 522, and at this time, the second door body 3 is opened.

[0092] In addition, the connecting arm 53 can be curved towards the inside of the vehicle body to form a curved arm; and / or, the connecting arm 53 includes a first connecting arm 531 and a second connecting arm 532 connected detachably, the first connecting arm 531 is connected with the first hinge part 51, and the second connecting arm 532 is connected with the second hinge part 52.

[0093] Wherein, as Figure 19 and Figure 20As shown, the second hinge seat 521 can be connected with the rear floor inner wheel cover reinforcement plate 11 of the vehicle body 1, so that no arrangement space needs to be reserved on the C pillar of the vehicle, and the size of the C pillar is not increased, and the modeling seam line is not limited. Secondly, by arranging the second hinge seat 521 on the rear floor inner wheel cover reinforcement plate 11, the installation strength and rigidity requirements of the second door body 3 can be effectively met. In addition, by arranging the second hinge seat 521 on the rear floor inner wheel cover reinforcement plate 11, the size of the door hole of the second door body in the first direction A is not affected, and the wheelbase of the vehicle does not need to be increased to meet the getting-on and getting-off requirements. The connecting arm 53 can be bent towards the inner side of the vehicle body to form a swan neck structure, and the connecting arm 53 can include a detachable first connecting arm 531 and a second connecting arm 532, so that one of the first connecting arm 531 and the second connecting arm 532 can be connected with the first hinge seat 511, and the other can be connected with the second hinge seat 521, so that the first hinge seat 511 can be connected with the second door body 3 first, and the second hinge seat 521 can be connected with the vehicle body 1 first, and the two connecting arms are connected and matched when the second door body 3 is connected with the vehicle body 1. Therefore, the efficiency of connecting the second door body 3 with the vehicle body 1 is improved, and in addition, the split design of the first connecting arm 531 and the second connecting arm 532 can also be used to adjust the gap difference between the second door body 3 and the vehicle body 1. Of course, the connecting arm 53 can also be configured as an integral structure to facilitate the molding of the hinge assembly 5.

[0094] In addition, it should be noted that although the rotating side of the second door body 3 is inclined at a certain angle relative to the first door body 2 towards the outer side of the vehicle body 1 when moving along the first track, since there is originally a gap between the first lap joint area 21 and the second lap joint area 31, and the two are sealed and matched by a deformable sealing structure such as a sealing strip, and the inclination angle is small, even if the second door body is inclined, there will be no interference between the first door body 2 and the second door body 3. Therefore, it is ensured that the opening side of the second door body 3 can move towards the second position and be normally opened.

[0095] In summary, the disclosure exemplarily shows the opening and closing process of the second door body of the split door vehicle in the case of using the above-mentioned lock catch assembly 4 and hinge assembly 5.

[0096] When the second door body 3 is opened, the second lock catch assembly 6 is first unlocked from the vehicle body 1, and the rotating side of the second door body 3 is first rotated by a first angle about the first pivot axis L outwardly from the vehicle body 1 to disengage from the vehicle body 1, and the opening side of the second door body 3 that is locked with the lock catch body 421 is moved from the first position to the second position by the action of the pulley set 425 and the connecting member 4231 provided on the lock catch base plate 422, until the rotating side of the second door body 3 moves to the second position, the lock catch body 421 is unlocked from the rotating side of the second door body 3, and then the rotating side of the second door body 3 can be rotated by a second angle about the first pivot axis L outwardly from the vehicle body 1 to be opened, thus achieving the opening of the second door body 3. When the second door body 3 is closed, the opening side of the second door body 3 is first rotated by the second angle about the first pivot axis L toward the vehicle body 1 to be locked with the lock catch body 421 at the second position, and then the rotating side of the second door body 3 is rotated by the first angle about the first pivot axis L toward the vehicle body 1, and the opening side of the second door body 3 is moved from the second position to the first position by the action of the pulley set 425 and the connecting member 4231, until the opening side of the second door body 3 moves to the first position, the rotating side of the second door body 3 is also fitted with the vehicle body 1, and finally the second lock catch assembly 6 is locked with the vehicle body 1 to ensure the stability of the second door body 3 in the closed state, thus achieving the closing of the second door body 3. The rotating side of the second door body 3 of the double-door vehicle in the present disclosure is away from or close to the vehicle body 1 on the first track under the action of the hinge assembly 5 at the time of opening and closing, and at the same time, the opening side of the second door body 3 can be away from or close to the second door body 3 in the first direction A, so that the opening side of the second door body 3 does not interfere with the first door body 2 when opening or closing along the second track, and the first door body 2 and the second door body 3 of the double-door vehicle do not interfere with each other at the time of opening and closing, thus realizing the disordered opening of the double-door vehicle and improving the user experience.
