In order to facilitate understanding of the vehicle door assembly provided in the embodiments of the present application, first, an application scenario thereof will be described. The vehicle door assembly is applied to an automobile. The door assembly is used for an assembly for opening and closing the vehicle, and when passengers get on or off the vehicle, the doors are required to be opened, but when the current doors are opened, the space occupied in the Y direction of the vehicle is larger, so that the vehicle needs to occupy a larger space when parked. Therefore, the embodiment of the application provides a vehicle door assembly, which reduces the Y-direction space occupied by the vehicle door when being opened, and is convenient for a user to park. The following description is made with reference to specific drawings and examples.

First, the XYZ direction of the car is defined, wherein the X direction is the length direction of the car, the Y direction is the width direction of the car, and the Z direction is the height direction of the car. In the practice of the present application, the Y direction is also referred to as the first direction and the X direction is also referred to as the second direction.

Referring to fig. 1, fig. 1 shows a schematic structural diagram of a vehicle door assembly according to an embodiment of the present application. The vehicle door assembly is used for achieving connection between the vehicle door and a vehicle and achieving opening and closing functions of the vehicle door. The door assembly includes a retracting mechanism 10, a first driving mechanism 20, and a door. Wherein, the telescopic mechanism 10 is used for adjusting the position of the vehicle door in the Y direction, the first driving mechanism 20 is used for driving the telescopic mechanism 10 to stretch and retract along the Y direction, and the vehicle door is hinged with the telescopic mechanism 10 so as to open the vehicle door through rotation. In the structure shown in fig. 1, a vehicle door is not illustrated, and a specific position thereof may refer to a position of a moving lever 30 of a component in fig. 1, and the moving lever 30 is a structure in which the telescopic mechanism 10 is connected to the vehicle door. In the embodiment of the application, the opening mode of the vehicle door comprises the following steps: the door is first driven by the telescopic mechanism 10 to move horizontally in a direction away from the vehicle body in the Y direction to leave a space required for the door to rotate, and then the door is rotated about the hinge axis (the rotation direction is counterclockwise as shown by one arrow in the arcuate line with the double-headed arrow in fig. 1, and the other direction is the direction in which the door is rotated when the door is closed) to effect opening of the door. The specific structure of each component in the door assembly is described in detail below in conjunction with the specific figures.

With continued reference to fig. 1, the telescopic mechanism 10 provided in the embodiments of the present application is fixed on the chassis when configured, so as to serve as a connecting structure to fixedly connect the door assembly with the chassis. When specifically provided, the telescopic mechanism 10 may be provided below the chassis or embedded in the chassis. The telescopic mechanism 10 extends in the Y direction and can reciprocate in the Y direction to drive the vehicle door to translate in the Y direction. Illustratively, when the door is open, the telescoping mechanism 10 is extended and the door is translated outwardly; when the door is closed, the telescopic mechanism 10 contracts, and the door translates to the vehicle side.

In one embodiment, the telescoping mechanism 10 may be a linkage of telescoping mechanisms 10. Illustratively, the telescoping mechanism 10 includes struts hinged end-to-end, with four struts enclosing a parallelogram structure to effect a change in position in the Y-direction by deformation of the parallelogram. For convenience of description, four struts are respectively named as a first strut 11, a second strut 12, a third strut 13, and a fourth strut 14. Wherein the first stay 11 is parallel to the second stay 12, and the third stay 13 is parallel to the fourth stay 14.

When the first stay bar 11 and the second stay bar 12 are specifically arranged, the first stay bar 11 and the second stay bar 12 are arranged at intervals along the Y direction, and the length direction of the first stay bar 11 and the second stay bar 12 extends along the X direction; and the third stay bar 13 and the fourth stay bar 14 are hinged with the first stay bar 11 and the second stay bar 12 as connecting rods.

The first stay 11 and the second stay 12 are used as functional rods of the telescopic mechanism 10 to realize telescopic operation in the Y direction. The first stay 11 is for example intended for a fixed connection with the chassis. When the telescopic mechanism 10 is fixed to the chassis, the first stay 11 is fixed to the chassis of the vehicle to fixedly connect the entire telescopic mechanism 10 to the chassis. The second stay 12 is for articulation with the vehicle door. When the door is assembled to the telescopic mechanism 10, the door is hinged to the second stay 12 and is rotatable relative to the second stay 12.

The telescopic mechanism 10 provided in the embodiment of the present application realizes the expansion and contraction in the Y direction by the deformation of the parallelogram structure. Illustratively, as the distance in the Y direction between the second stay 12 and the first stay 11 increases, the door translates to the vehicle outside; when the distance between the second stay 12 and the first stay 11 in the Y direction decreases, the door translates to the vehicle side.

When the structure is adopted, the whole length direction of the telescopic mechanism 10 extends along the X direction, and occupies a smaller space in the Y direction, so that the space occupied by the whole telescopic mechanism 10 in the Y direction is smaller, and the telescopic mechanism 10 is conveniently arranged on the chassis. In particular, in the case of a side-by-side door arrangement of a vehicle, two telescopic mechanisms 10, which can be arranged with a large space in the Y direction on the chassis, each correspond to two vehicle doors.

When the telescopic mechanism 10 is driven to extend and retract in the Y direction, the telescopic mechanism 10 can be driven to move by the first driving mechanism 20. In one embodiment, the first drive mechanism 20 may be driven using a link slider 22 mechanism. The first driving mechanism 20 includes a driving rod 23, a driving member 21, and a sliding member 22, wherein the sliding member 22 is slidably mounted on the first stay 11 and is slidable along the length direction of the first stay 11, i.e., in the X direction. And the driving member 21 is used for driving the sliding member 22 to slide on the first stay 11. Both ends of the driving rod 23 are hinged with the sliding parts 22 and the second supporting rods 12 in a one-to-one correspondence manner. Such as a drive rod 23 having one end hinged to the slider 22 and an opposite end hinged to the second stay 12.

When the second stay bar 12 is driven to move along the Y direction, the sliding piece 22 can slide on the first stay bar 11 along the X direction, so that one end of the driving rod 23 is driven to slide on the first stay bar 11, and since the other end of the driving rod 23 is hinged with the second stay bar 12 and the length of the driving rod 23 is fixed, when the sliding piece 22 slides, the driving rod 23 rotates around the second stay bar 12 and can drive the second stay bar 12 to move along the Y direction. Illustratively, when the driving member 21 drives the sliding member 22 to slide, the driving rod 23 rotates around the second supporting rod 12, and the included angle between the driving rod 23 and the second supporting rod 12 increases, at this time, the second supporting rod 12 is far away from the first supporting rod 11, and the vehicle door is driven to the outside of the vehicle; when the driving piece 21 drives the sliding piece 22 to slide, the driving rod 23 rotates around the second supporting rod 12, the included angle between the driving rod 23 and the second supporting rod 12 is reduced, at this time, the second supporting rod 12 is close to the first supporting rod 11, and the vehicle door is driven to be close to the vehicle.

In the above-described embodiment, when the telescopic mechanism 10 moves in the Y direction, the second stay 12 also moves in the X direction by a certain extent, but since the translational dimension of the second stay 12 in the Y direction is small (the thickness of the door or smaller), the displacement of the second stay 12 in the X direction is also small, so that the opening and closing of the door is not affected. In addition, since the second stay 12 has a certain displacement in the X direction, when the door is opened and closed, the door is not inserted into the door frame vertically in the Y direction but is inserted into the door frame in an oblique cutting manner, so that the door is convenient to be matched with the door frame, and the gap between the door and the door frame can be reduced.

In the embodiment of the application, the driving member 21 adopts a reciprocating sliding manner when driving the sliding member 22, so that the vehicle door can be far away from or near the vehicle. For example, the driving member 21 provided in the embodiment of the present application is a telescopic member, so that the sliding member 22 is driven to reciprocate in the X direction by the telescopic movement of the driving member 21, and further, the second supporting rod 12 is driven to reciprocate in the Y direction.

As an alternative, the driving rod 23 is provided with a lug on the slider 22, to which one end of the driving rod 23 is hinged, when hinged with the slider 22 and the second stay 12, respectively. In addition, the other end of the driving rod 23 is hinged to one end of the second stay 12, and as shown in fig. 1, the other end of the driving rod 23 is hinged to the second stay 12 at a position where the third stay 13 is hinged to the second stay 12, the driving rod 23, and the third stay 13 by one hinge shaft. It should be understood that the position where the driving rod 23 is hinged to the second supporting rod 12 in the above example is only an example, and in the embodiment of the present application, the hinge position of the driving rod 23 and the second supporting rod 12 may be located at other positions, and only the driving rod 23 may be used to drive the second supporting rod 12 to move along the Y direction.

As an alternative, the driving member 21 may be a driving cylinder, a driving hydraulic cylinder, and an electric telescopic rod. When connected to the slider 22, the driving member 21 is hinged at one end to the first stay 11 and at the other end to the slider 22. And the length direction of the driving piece 21 is along the X direction, so that the length direction of the driving piece 21 is parallel to the length direction of the first stay bar 11, the space occupied by the driving piece 21 in the Y direction is reduced, and the whole vehicle door assembly is convenient to set.

With continued reference to fig. 1, when the driving member 21 is connected to the first stay 11 and the slider 22, respectively, one end of the driving member 21 is hinged to one end of the first stay 11. Specifically, one end of the first stay 11 hinged to the third stay 13. A projection structure is provided at the end of the first stay 11, to which one end of the driving member 21 is hinged. In addition, the slider 22 is provided with a lug, and the other end of the driver 21 is hinged to the lug. When the driving rod 23 and the driving member 21 are hinged to the sliding member 22, respectively, the two lugs are arranged on opposite sides of the sliding member 22. Illustratively, the drive rod 23 and the drive member 21 are respectively arranged on opposite sides of the first stay 11, and two lugs are respectively arranged on opposite sides of the first stay 11.

As an alternative, the driving member 21 is hinged at one end to the first stay 11 and at the other end to the slider 22. Therefore, the requirements on assembly precision can be reduced through the machining errors of the hinged absorbing parts at the two ends of the driving part 21 and the assembly errors among the parts, and the whole device is convenient to assemble.

The first driving mechanism 20 illustrated above is only one specific example. It should be appreciated that the first drive mechanism 20 provided by the embodiments of the present application is not limited to the examples described above. Other similar schemes may also be employed. As in the alternative, the driving member 21 is fixed to the first stay 11, and the driving member 21 is directly hinged to the driving rod 23, the effect of moving the second stay 12 in the Y direction can be achieved as well.

When the second stay 12 is hinged to the door, the second stay 12 may be hinged to the door by the moving rod 30. Illustratively, the door is fixedly coupled with a motion bar 30, and the motion bar 30 is hinged with the second stay 12 to be hinged with the door by the motion bar 30. Thereby facilitating the connection of the door to the second stay 12. It will be appreciated that the axis of articulation of the movement bar 30 with the second strut 12 is in the Y direction so that the door can be rotated in an axis perpendicular to the Y direction when rotated, thereby reducing the space occupied by the door in the Y direction when opened.

It should be appreciated that the motion bar 30 of the above example is an alternative, and that the door may be directly hinged to the telescopic mechanism 10 in the embodiment of the present application, and the door may be rotated as well.

As an alternative, the door assembly provided in the embodiments of the present application may further include a second driving mechanism 40, where the second driving mechanism 40 is used to drive the door to rotate, so as to facilitate opening the door. Illustratively, when the door is opened, the telescopic mechanism 10 is first driven by the first driving mechanism 20 to move outwards along the Y direction, and then the door is driven by the second driving mechanism 40 to rotate, so that the door is opened; when the door is closed, the door is first driven to rotate in the opposite direction by the second driving mechanism 40, and then the telescopic mechanism 10 is driven to move in the Y direction toward the vehicle body side by the first driving mechanism 20, thereby closing the door.

As an example, the second driving mechanism 40 may also be the telescopic mechanism 10, and the telescopic mechanism 10 may be a driving cylinder, a driving hydraulic cylinder, and an electric telescopic rod. When connected to the second stay 12 and the movement bar 30, one end of the second driving mechanism 40 is hinged to the second stay 12, and the other end is hinged to the movement bar 30. The door can be rotated by the expansion and contraction of the second driving mechanism 40, thereby realizing the opening and closing of the door.

It should be understood that the telescopic mechanism 10 provided in the embodiments of the present application may be implemented using other telescopic mechanisms 10 besides the parallelogram mechanism described above. Illustratively, the telescoping mechanism 10 may also be of unitary construction with the drive mechanism. If the telescopic mechanism 10 with driving such as a driving cylinder, a driving hydraulic cylinder and a linear telescopic rod is adopted, the driving of the vehicle door in the Y direction away from the vehicle body can be realized.

In addition, in addition to the above-described example, a parallelogram-like structure may be employed, such as a link mechanism in which the telescopic mechanism 10 is an isosceles trapezoid, in which the first stay 11 and the second stay 12 are still functional rods, and the third stay 13 and the fourth stay 14 are waists of the trapezoid link mechanism. The first stay bar 11 is a telescopic rod and is fixedly connected with the chassis, and the second stay bar 12 is hinged with the vehicle door. The driving mechanism may be a first telescopic rod, for example, the first telescopic rod may be a driving cylinder or a driving hydraulic cylinder or an electric telescopic rod which can be telescopic in two directions. When the first stay bar 11 stretches and contracts, the length of the first stay bar 11 changes, and the second stay bar 12 is driven to translate along the Y direction through the third stay bar 13 and the fourth stay bar 14. The effect of driving the door in the Y direction to move can also be achieved.

As can be seen from the above description, the vehicle door assembly provided in the embodiment of the present application drives the vehicle door to move along the direction of the width of the vehicle by using the telescopic mechanism 10, and drives the vehicle door to rotate around the axis parallel to the direction of the width of the vehicle, thereby greatly reducing the space occupied by the vehicle door when opening. The space occupied by opening and closing the vehicle door after the vehicle is parked is reduced, so that the vehicle is convenient to park.

An embodiment of the present application provides an automobile, including a chassis, and a door assembly of any one of the above; wherein, telescopic machanism 10 in the door subassembly and chassis fixed connection. In particular arrangements, the telescoping mechanism 10 is secured to the chassis and serves as a support structure for the entire door assembly, as described in detail with respect to FIG. 1. The automobile provided by the embodiment of the application can be a sedan, SUV or MPV type. In the above technical scheme, the door assembly of the automobile drives the door to move along the direction of the width of the automobile by adopting the telescopic mechanism 10, and then drives the door to rotate around the axis parallel to the direction of the width of the automobile, so that the occupied space of the door when the door is opened is greatly reduced.
