[0039] The utility model proposes a swing door mechanism for a car, a control method and a car comprising the same, aiming to solve the problem of the complex structure of the existing swing door mechanism. After the swing door mechanism is applied to a private car, it can not only greatly reduce the occupied space, but also realize the ultra-wide angle opening of the swing door, which is convenient for passengers to enter and exit, and effectively improves the comfort of the user.

[0040] The following embodiments will be used to describe in detail a swing door mechanism for a vehicle, a control method and a vehicle comprising the same according to the present application.

[0041] Embodiment 1:

[0042] like Figure 1-Figure 6 As shown, in this embodiment, a swing door mechanism for a car is provided, wherein the car comprises: a body 10 and a swing door 20, and the swing door mechanism comprises:

[0043] The slide rail 100 is a linear slide rail 100 and is horizontally installed on the inner side of the swing door 20;

[0044] The slider 200 is slidably disposed on the slide rail 100;

[0045] The connecting rod assembly 300 has a first connecting end and a second connecting end, the first connecting end of the connecting rod assembly 300 is connected to the slider 200, and the second connecting end of the connecting rod assembly 300 is rotatably disposed on the vehicle body 10;

[0046] The first driving assembly 400 is used to adjust the relative position between the slide rail 100 and the slider 200;

[0047] The second driving assembly 500 is used to drive the slider 200 and the slide rail 100 to rotate with the first connecting end of the connecting rod assembly 300 as a rotation point;

[0048] The third driving assembly 600 is connected to the second connecting end of the connecting rod assembly 300 and is used to drive the connecting rod assembly 300 to move so that the slider 200 and the slide rail 100 move closer to or away from the second connecting end of the third driving assembly 600;

[0049] And a control unit 700 is used to control the operating states of the first driving assembly 400 , the second driving assembly 500 and the third driving assembly 600 .

[0050] In the present technical solution, the control unit 700 controls the first drive assembly 400 , the second drive assembly 500 and the third drive assembly 600 respectively, thereby changing the position of the slide rail 100 , that is, the position of the swing door 20 , and further realizing the opening and closing of the swing door 20 .

[0051] Specifically, since the slider 200 is hinged with the connecting rod assembly 300 and the slider 200 is limited, when the first driving assembly 400 is running, the slide rail 100 will slide on the slider 200, thereby causing the swing door 20 to move toward the rear of the vehicle body 10, or to move toward the front of the vehicle body 10; since when the swing door 20 is closed on the vehicle body 10, it is coplanar with the outer side of the vehicle body 10, and therefore the swing door 20 cannot be moved backward directly, for this purpose a second driving assembly 500 is provided, and the slide rail 100 is driven to rotate by the second driving assembly 500, so that the swing door 20 can be rotated, so that the rear side of the swing door 20 is offset toward the outside, and then the side sliding of the swing door 20 can be realized.

[0052] Of course, for the swing door 20, the size of its opening is particularly important. For small cars, due to the limitation of its own frame, the swing door 20 can generally only be opened about halfway, which makes it inconvenient for passengers to get on and off the car. For this reason, a connecting rod assembly 300 and a third drive assembly 600 are also provided. By driving the third assembly to operate, the connecting rod assembly 300 can push the slide rail 100 and the swing door 20 outward, so that the space between the swing door 20 and the car body 10 can accommodate passengers. Such an arrangement can greatly solve the problem of difficulty in getting on and off the car for passengers.

[0053] Embodiment 2:

[0054] This embodiment is a further improvement made on the basis of the first embodiment.

[0055] like Figure 1-Figure 6 As shown, in this embodiment, the connecting rod assembly 300 is a four-bar connecting rod mechanism, and the four-bar connecting rod mechanism is in the shape of a parallelogram.

[0056] Specifically, the four-bar linkage includes: a first link 310, a second link 320, a third link 330 and a fourth link 340, wherein the first link 310, the second link 320, the third link 330 and the fourth link 340 are hinged end to end in sequence;

[0057] The first connecting end is located on the first connecting rod 310 , the second connecting end is located on the third connecting rod, and the lengths of the first connecting rod 310 and the third connecting rod 330 are smaller than the lengths of the second connecting rod 320 and the fourth connecting rod 340 .

[0058] In the present technical solution, the first connecting rod 310, the second connecting rod 320, the third connecting rod 330 and the fourth connecting rod 340 are all plate-like members, and pin holes are provided at both ends of the four connecting rods, which are hinged to each other end to end through pin shafts.

[0059] The second driving assembly 500 is fixed on the first connecting rod 310, and a protrusion with a hole is provided on the side of the slider 200 close to the first connecting rod 310, and a protrusion with a hole is provided on the side of the first connecting rod 310 close to the slider 200. The holes on the two protrusions are connected by a pin shaft, so that the slider 200 can rotate relative to the first connecting rod 310.

[0060] The output shaft of the third driving assembly 600 is fixedly connected to the first connecting rod 310 .

[0061] When in use, the third driving assembly 600 drives the third connecting rod 330 to rotate, so that the angles between the two adjacent connecting rods are changed, so that the swing door 20 moves outward relative to the vehicle body 10, and then under the action of the first driving assembly 400, the door slides sideways relative to the side wall of the vehicle body 10, thereby realizing the movement of the swing door 20.

[0062] It is worth noting that in this embodiment, a connecting rod close to the third driving assembly 600 is used as the third connecting rod 330. In actual practice, the third connecting rod 330 can be any one of the above four connecting rods.

[0063] Embodiment three:

[0064] This embodiment is a further improvement made on the basis of the first or second embodiment.

[0065] like Figure 1 As shown, in this embodiment, the first driving assembly 400 includes: a first driving motor 410 and a screw rod 420;

[0066] Among them, the screw rod 420 is arranged in the slide rail 100, the slider 200 is threadedly connected to the screw rod 420, and the first drive motor 410 is connected to the screw rod 420. The screw rod 420 is driven to rotate by the first drive motor 410, so that the slide rail 100 moves relative to the slider 200, so that the swing door 20 can slide sideways.

[0067] In this embodiment, the second driving assembly 500 includes: a second driving motor 510, a gear 520 and a tooth portion 530;

[0068] Among them, the output end of the second driving motor 510 is connected to the gear 520, and the tooth portion 530 is arranged on the slider 200 and meshes with the gear 520. When the second driving motor 510 is running, the gear 520 drives the tooth portion 530 to rotate, thereby driving the slider 200 and the slide rail 100 to rotate.

[0069] In the present technical solution, the second drive motor 510 is mounted on the first connecting rod 310, and the gear 520 is fixed on the output shaft of the second drive motor 510. When the second drive motor 510 is turned on, the slider 200 is driven to rotate around the hinge between the slider 200 and the first connecting rod 310 under the action of the gear 520 and the tooth portion 530, thereby adjusting the relative angle between the slide rail 100 and the swing door 20 and the vehicle body 10.

[0070] It is worth noting that the tooth portion 530 can be replaced by another gear, and the other gear is fixedly disposed on the slider 200 , and the angle of the swing door 20 can be adjusted through the action of the other gear and the above-mentioned gear 520 .

[0071] In this embodiment, the third drive assembly 600 includes: a third drive motor 610, a reducer 620 and an output member; the first drive motor 410 is connected to the input end of the reducer 620, one end of the output member is connected to the output end of the reducer 620, and the other end is connected to the second connecting end of the connecting rod assembly 300.

[0072] Embodiment 4:

[0073] This embodiment provides a control method for a swing door mechanism of an automobile. The control method is used to control the swing door mechanism of the automobile in any of the above embodiments. The method of controlling the swing door to open is as follows:

[0074] S1, the control unit 700 controls the second driving assembly 500 to operate, so that the swing door 20 rotates a certain angle with the first connection end of the connecting rod assembly 300 as the rotation point;

[0075] S2, the control unit 700 controls the third driving assembly 600 to operate, so that the swing door 20 takes the second connection end of the connecting rod assembly 300 as a reference point and moves away from the reference point by a certain distance;

[0076] S3, the control unit 700 controls the first driving assembly 400 to operate, so that the swing door 20 moves toward the rear side of the vehicle body 10;

[0077] S4. The control unit 700 controls the third driving assembly 600 to continue to operate, so that the swing door 20 takes the second connection end of the connecting rod assembly 300 as a reference point and moves away from the reference point to a maximum distance.

[0078] Optimally, the control method further includes a step S5 after step S3 or S4, wherein step S5 is: the control unit 700 controls the second driving assembly 500 to operate so that the angle of the swing door 20 opened in step S1 is reset.

[0079] In this technical solution, in order to prevent the swing door 20 from interfering with the outer wall of the vehicle body 10 when sliding sideways, the second driving assembly 500 is used to rotate the swing door 20 so that its rear side is located outside the vehicle body 10, and then the third driving assembly 600 is used to push the swing door 20 outward for a short distance, and then the first driving assembly 400 is used to drive the swing door 20 to slide sideways, and then the second driving assembly 500 drives the swing door 20 to rotate in the opposite direction to reset, and at the same time the third driving assembly 600 is operated again to push the swing door 20 outward along the outer wall of the vehicle body 10 to achieve the maximum opening. This setting can not only maximize the space for passengers to get on and off the vehicle, but also the swing door 20 is smooth when opening and closing, and occupies little space.

[0080] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
