[0037] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0038] A swing-type car door system includes a car door 1, which is connected to the car body via a main drive system 2. The main drive system 2 disclosed in this invention can realize the swing-type opening of the car door, which changes the traditional sliding rail and side-opening door opening methods.

[0039] Meanwhile, the main drive system 2 of the present invention has a simple overall structure, which can avoid the problem of excessive linkage occupying the sill space in traditional door opening drive systems; and avoids occupying the passenger compartment space.

[0040] The swing door system disclosed in this invention is fundamentally different from the existing side-opening door. The swing door system disclosed in this invention can realize the front and rear opening of the door by rotation, which can reduce the lateral space required when the door is opened, and thus reduce the lateral space required when parking.

[0041] In addition, the swing door system disclosed in this invention includes a door, which is connected to the vehicle body through a main drive system 2; the main drive system 2 disclosed in this invention is a drive end, mainly used for subsequent opening and closing control of the door.

[0048] Furthermore, the swing door system described in this invention also includes a lock system 23; the lock system 23 includes a latch 232 disposed on the second main drive rod 222 or the door and a lock body 231 disposed on the vehicle body; the lock body 231 includes a lock body 231 body, and the lock body 231 body is provided with a lock groove 2311; the present invention can realize a fixed connection between the door and the vehicle body by using the lock body 231 and the latch 232 in cooperation.

[0049] In this invention, the lock groove 2311 includes a guide straight section 23111; the guide straight section 23111 is arranged parallel to the X direction of the vehicle; the guide straight section 23111 is located inside the lock groove 2311, and this invention requires the guide straight section 23111 to be arranged parallel to the X direction of the vehicle; such an arrangement can realize the closing shape correction of the door and ensure the accuracy of the door closing position.

[0050] Furthermore, in this invention, the lock groove 2311 also includes a transition section 23112; the guide straight section 23111 is connected to the outer surface of the lock body 231 through the transition section 23112; the transition section 23112 is inclined, one end of the transition section 23112 is connected to the guide straight section 23111, and the other end extends outward of the vehicle body; the present invention, through the setting of the transition section 23112, plays a good transition operation, which facilitates the guidance between the door and the lock body 231 before locking and before disengaging from the previous guidance; that is, it facilitates the guidance between the latch 232 and the lock body 231 before locking or unlocking during subsequent use, and at the same time, it can also limit the running trajectory of the door to avoid interference between the door and adjacent components.

[0051] Furthermore, the swing door system described in this invention also includes an auxiliary support system 3; the auxiliary support system 3 provides excellent auxiliary support and ensures the stability of the door when it is opened.

[0052] In this invention, the auxiliary support system 3 includes a second telescopic rod 33; one end of the second telescopic rod 33 is movably connected to the vehicle body, and the other end is movably connected to the door; the second telescopic rod 33 of this invention acts as an adjusting component, which can adjust the balance of the door during operation and the orientation position of the door as needed; similarly, the first telescopic rod 24 can also adjust the position of the door through its own extension and retraction.

[0053] Furthermore, the auxiliary support system 3 described in this invention includes a three-bar linkage 32; the three-bar linkage 32 essentially adds a parallelogram structure to the door, which cooperates with the main drive system 2 to achieve smooth operation of the door.

[0054] Specifically, the three-bar linkage 32 described in this invention includes a first auxiliary link 321 connected to the vehicle body and a third auxiliary link 323 connected to the door; the first auxiliary link 321 is connected to the third auxiliary link 323 via a second auxiliary link 322; one end of the second telescopic rod 33 is connected to the third auxiliary link 323, and the other end is connected to the first auxiliary link 321; the first auxiliary link 321, the second auxiliary link 322, and the third auxiliary link 323 are interconnected, and adjacent connections are made by rotation.

[0055] In addition, in this invention, the main drive system 2 and the auxiliary support system 3 are distributed above and below the vehicle body, with the main drive system 2 located below the vehicle body and the auxiliary support system 3 located above the vehicle body. Based on the above design, it is convenient to realize the door opening operation through the cooperation of the main drive system 2 and the auxiliary support system 3 in subsequent use.

[0056] Furthermore, in this invention, the first auxiliary connecting rod 321 is connected to the vehicle body via the second mounting bracket 31; the second mounting bracket 31 serves as a mounting and fixing mechanism, facilitating the connection between the auxiliary support system 3 and the vehicle body.

[0057] A vehicle including the swing door system.

[0058] specific:

[0059] The purpose of this invention is to meet the needs of spacious vehicle entry and exit, less parking space, and a body without B-pillars, allowing the front and rear doors to open and close in any order. It also solves the problems of existing technologies occupying passenger compartment space and multiple linkages occupying sill space. Therefore, a swing door system is proposed. The swing door system disclosed in this invention is mainly a swing door opening and closing system.

[0060] The swing door system disclosed in this invention mainly includes a door, a body, a main drive system 2, a lock system 23, and an auxiliary support system 3.

[0061] The main drive system 2 disclosed in this invention mainly includes a first mounting bracket 21 and a two-bar linkage 22.

[0062] The auxiliary support system 3 includes a second mounting bracket 31, a three-bar linkage 32, and a second telescopic rod 33.

[0063] In this invention, the main drive system 2 is arranged in the lower sill area of ​​the vehicle body to provide driving force for opening and closing the door and to maintain the door position.

[0064] The driver function of the main drive system 2 is to provide power to drive the first main drive rod 221 in the two-link mechanism 22 to rotate. Its power is selected according to parameters such as the weight of the door.

[0065] The first mounting bracket 21 of the main drive system 2 is used to firmly fix the main drive system 2 to the vehicle frame and to provide a connection for the driver to drive the first main drive rod 221. That is, the two linkage mechanism 22 is connected to the first mounting bracket 21 through the shaft. The driver drives the shaft to rotate, thereby driving the two linkage mechanism 22 to rotate.

[0066] The two-bar linkage 22 of the main drive system 2 consists of two rods connected by a pin. The two rods can rotate relative to each other around the pin.

[0067] One of the main rods is the first main drive rod 221, which is a power rod that drives the system to rotate by receiving driving force from the driver.

[0068] The first main drive rod 221 has a protruding structure for mounting one end of the first telescopic rod 24.

[0069] The other rod, the second main drive rod 222, is used to connect to the door and drive the door to move. This rod has a protruding structure for mounting the other end of the first telescopic rod 24.

[0070] Meanwhile, there is another protruding structure on the second main drive rod 222 for fixing the latch 232.

[0071] The main drive system 2 is fixed to the vehicle body frame, and the latch 232 is fixed to the main drive system 2.

[0072] When the door is closed, it serves to lock the door.

[0073] The locking groove 2311 includes a guide straight section 23111 and a transition section 23112.

[0074] It plays a guiding role during the first stage of movement of the swing door system.

[0075] Its function is to guide the structure of the rear door at the B-pillar into the motion trajectory of the two-link mechanism 22 and ensure a safe distance from the front door.

[0076] This ensures that the rear door maintains a sufficient safe distance from the front door during opening and closing.

[0077] The back door can be opened and closed without requiring any action from the front door.

[0078] The guide straight section 23111 is a lock guide structure, and the length of the specific guide straight section 23111 depends on the required size for guiding the rear door into the movement trajectory.

[0079] The first telescopic rod 24 of the main drive system 2 is mounted on the first main drive rod 221 at one end and on the second main drive rod 222 at the other end.

[0080] The first telescopic rod 24 is rotatably connected to the first main drive rod 221 and the second main drive rod 222. The connection method can be a pin or a rotating shaft, etc.

[0081] In the second stage of the swing door system's movement, the second telescopic rod 33 changes its length by extending and retracting, thereby maintaining the door's posture during the opening and closing process and keeping the door parallel to the vehicle body when fully open.

[0082] The auxiliary support system 3 is located in the upper part of the vehicle body and keeps the door position stable during the opening and closing process.

[0083] The second mounting bracket 31 of the auxiliary support system 3 securely fixes the auxiliary support system 3 to the vehicle body frame.

[0084] The three-bar linkage 32 of the auxiliary support system 3 is connected by a pin and can rotate relative to each other. One of the bars is connected to the second mounting bracket 31 by a pin and can rotate relative to each other.

[0085] The rod has a protruding structure for mounting one end of the second telescopic rod 33.

[0086] Another rod is connected to the car door. This rod has a protruding structure for connecting to one of the rods in the three-bar linkage. This rod also has a protruding structure for installing the other end of the second telescopic rod 33.

[0087] The second telescopic rod 33 of the auxiliary support system 3 is connected to the three-bar structure at both ends; it is used to keep the system stable during the opening and closing process.

[0088] Meanwhile, in this invention, the first stage is the process of the latch 232 moving out of or into the guide straight section 23111.

[0089] The second stage is the process of the latch 232 being moved out of or inserted into the transition section 23112.

[0090] The specific implementation method is as follows:

[0091] like Figure 1As shown, the present invention includes: a door 1, a main drive system 2, and an auxiliary support system 3.

[0092] The locking system 23 includes a lock body 231 and a latch 232.

[0093] The lock body 231 is provided with a lock groove 2311.

[0094] The first main drive rod 221 and the second main drive rod 222 of the present invention form a two-bar linkage 22; in the present invention, the two-bar linkage 22 drives the door 1 to open or close by receiving power from the driver.

[0095] The lock groove 2311 is divided into two sections: a guide straight section 23111 and a transition section 23112; the guide straight section 23111 is section L1, and the transition section 23112 is section L2.

[0096] The function of segment L1 is to guide the rear door 11 into the trajectory line during the rotation of the two linkage mechanism 22 at the defined angle. Figure 4 To ensure that the rear door 11 maintains a defined safe distance from the front door 12 during the continued opening process, the length of which depends on the required dimensions for guiding the rear door 11 into the trajectory line.

[0097] The function of segment L2 is to reliably guide the rear door 11 into segment L1 during the closing process.

[0098] The first telescopic rod 24 maintains the posture of the door 1 during the opening or closing process by changing its length, ensuring that the door 1 is parallel to the vehicle body when fully open.

[0099] The auxiliary support system 3 opens and retracts as the door 1 opens and closes, ensuring stable and reliable movement of the door 1.

[0100] The first mounting bracket 21 is fixed to the vehicle body frame (not shown).

[0101] The first pole is the first main drive pole, 221.

[0102] The first rod is connected to the first mounting bracket 21 via a pin and can rotate.

[0103] Rod No. 1 and Rod No. 2 are connected by a pin and can rotate relative to each other; Rod No. 2 is the second main drive rod 222.

[0104] The second rod is fixed to the door 1. The second rod has a protruding structure for fixing the latch 232.

[0105] Both pole number one and pole number two have protruding structures for connecting the second telescopic pole 33.

[0106] The lock body 231 is fixed to the vehicle frame.

[0107] The second mounting bracket 31 is fixed to the vehicle body frame (not shown).

[0108] The third pole has the first connecting link 321, the fourth pole has the second connecting link 322, and the fifth pole has the third connecting link 323.

[0109] The third rod is connected to the second mounting bracket 31 via a pin and can rotate.

[0110] Rod number four is connected to rod number three via a pin and can rotate relative to it. Rod number five is connected to rod number four via a pin and can rotate relative to it.

[0111] The fifth pole is fixed to door 1.

[0112] Both poles No. 3 and No. 5 have protruding structures for connecting the second telescopic pole 33.

[0113] In the first stage of the movement, namely the L1 segment working area of ​​the lock groove 2311.

[0114] The driver drives the two-bar linkage 22 to rotate through a defined angle, which causes the system to move a length of L1 within the lock groove 2311.

[0115] The two-link mechanism 22 drives the rear door 11 to enter through a rigid connection. Figure 4 Within the trajectory line shown, the rear door 11 is guaranteed to maintain a defined safe distance from the front door 12 during subsequent movement.

[0116] In the first stage of the movement, the first telescopic rod 24 can actively extend and retract to provide power.

[0117] It can also be passively extended and retracted to act as a damper and keep the system running smoothly.

[0118] In the first stage of movement, the auxiliary support system 3 moves with the door 1 through a rigid connection, maintaining the system's stable and reliable operation.

[0119] In the second stage of the movement, that is, the L1 section of the lock groove 2311 finishes working.

[0120] The drive mechanism 22 continues to rotate through a defined angle, which depends on the defined opening degree of the door 1 and the defined safe distance between the fully opened door 1 and the vehicle body.

[0121] In the second phase of the movement, the first telescopic rod 24 actively extends and retracts to maintain the posture of the door 1 during the opening or closing process, ensuring that the door 1 is parallel to the vehicle body when fully open.

[0122] Its telescopic length is defined based on factors such as the opening degree of door 1 and the parallelism between door 1 and the vehicle body when it is fully open.

[0123] In the second phase of the movement, the auxiliary support system 3 moves with the door 1 through a rigid connection, maintaining the system's stable and reliable operation.

[0124] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
