[0044] In the first aspect of the embodiment of the present application, Figure 1 and Figure 2 As shown, a vehicle door drive assembly is provided, the vehicle comprises a vehicle body 10 and a vehicle door 20, the drive assembly comprises a first drive member 30 and a transmission mechanism 40 connected to the first drive member 30;

[0045] At least a portion of the first driving member 30 is suitable for being arranged on the vehicle body 10 , and the transmission mechanism 40 is suitable for being connected to the vehicle door 20 . The transmission mechanism 40 is suitable for driving the vehicle door 20 to move relative to the vehicle body 10 under the drive of the first driving member 30 .

[0046] Specifically, the vehicle includes a vehicle body 10 and a door 20, and the door 20 can move relative to the vehicle body 10. The driving assembly includes a first driving member 30 and a transmission mechanism 40 connected to each other, and the first driving member 30 can drive the transmission mechanism 40 to move so that the door 20 can move away from or close to the vehicle body 10, thereby realizing the opening or closing operation of the door 20. Among them, at least part of the first driving member 30 is arranged on the vehicle body 10, which reduces the weight of the door 20, reduces the overall load of the door 20, improves the overall stability of the door 20 drive, and is easy to disassemble and assemble, saving production line assembly and maintenance man-hours.

[0047] In some embodiments, the vehicle door 20 is a vehicle tailgate, the vehicle body 10 includes a luggage compartment floor 11 or a luggage compartment side panel corresponding to the vehicle tailgate, and the first driving member 30 is suitable for being arranged on the luggage compartment floor 11 or the luggage compartment side panel.

[0048] Specifically, Figure 2 and Figure 3 As shown, the vehicle tailgate refers to the door at the vehicle luggage compartment (or trunk), such as the vehicle tailgate may be a lower door hinged to the vehicle body 10 at the vehicle luggage compartment. The first driving member 30 is at least partially disposed on the luggage compartment floor 11 or the luggage compartment side panel of the vehicle body 10, and the first driving member 30 is installed by utilizing the installation space of the luggage compartment in the vehicle body 10, thereby reducing the weight of the vehicle door 20, reducing the overall load of the vehicle door 20, and increasing the service life of the vehicle door 20.

[0049] In some embodiments, the first driving member 30 includes: a first driving rod 301 and a first driven rod 302, the first driven rod 302 is connected to the transmission mechanism 40, the first driving rod 301 is suitable for being arranged on the vehicle body 10, and the first driving rod 301 is used to drive the first driven rod 302 to telescopically move along its axial straight line.

[0050] Specifically, Figures 1 to 8As shown, the first driving member 30 includes a first driving rod 301 provided with a driving device and fixedly connected to the second supporting member 50, and a first driven rod 302 movably connected to the first driving rod 301 and fixedly connected to the transmission mechanism 40; wherein the driving device can be a motor, an electric push rod or a cylinder, etc.; the second supporting member 50 is fixedly arranged on the vehicle body 10, such as fixedly arranged on the luggage compartment floor 11 of the vehicle body 10, and the second supporting member 50 is fixed to the vehicle body 10 by welding, screwing, riveting, etc. The driving device drives the first driving rod 301 to move and drives the first driven rod 302 to move linearly along its axial direction, and the transmission mechanism 40 converts the linear movement of the first driven rod 302 into the rotational movement of the vehicle door 20, so that the vehicle door 20 can rotate relative to the vehicle body 10 to realize the opening or closing operation of the vehicle door 20.

[0051] Among them, the first driving member 30 is fixedly connected to the second supporting member 50, and the first driven rod 302 is fixedly connected to the transmission mechanism 40, and the fixed connection method can adopt a spherical pair connection. The use of a spherical pair connection means that a point ball socket is set on one of the two components, and a ball head is set on the other component, and the spherical pair connection is realized by the cooperation of the point ball socket and the ball head. Exemplarily, a point ball socket is set on the first driving member 30, and a ball head is set on the second supporting member 50; or, a ball head is set on the first driving member 30, and a point ball socket is set on the second supporting member 50. The principle of the subsequent spherical pair connection in this application is as follows, and the embodiments of this application will not be repeated.

[0052] In some embodiments, the transmission mechanism 40 includes: a push rod 41 and a motion conversion mechanism 42; wherein,

[0053] The first driving member 30 is connected to the push rod 41 through the motion conversion mechanism 42 , and the push rod 41 is suitable for being connected to the vehicle door 20 so as to drive the vehicle door 20 to rotate relative to the vehicle body 10 under the drive of the first driving member 30 .

[0054] Specifically, Figures 2 to 8 As shown, the transmission mechanism 40 includes: a push rod 41 and a motion conversion mechanism 42, wherein the two ends of the motion conversion mechanism 42 are fixedly connected to the first driven rod 302 and the push rod 41, respectively, such as by a spherical pair connection. The push rod 41 is fixedly connected to the vehicle door 20, for example, the push rod 41 and the vehicle door 20 are connected by a spherical pair, that is, a ball head is provided on the push rod 41, and a point ball socket is provided on the vehicle door 20; or, a point ball socket is provided on the push rod 41, and a ball head is provided on the vehicle door 20. The motion conversion mechanism 42 converts the linear movement of the first driven rod 302 into a rotational movement in a horizontal plane. The push rod 41 moves along a straight line driven by the motion conversion mechanism 42, and drives the vehicle door 20 to rotate in a vertical plane around the rotation axis 60 of the vehicle body 10, so as to realize the opening or closing operation of the vehicle door 20.

[0055] like Figure 2 As shown, the direction of the front and rear of the vehicle is the x direction in the three-dimensional coordinate system, the direction of the doors 20 on the left and right sides of the vehicle cockpit is the y direction in the three-dimensional coordinate system, and the direction of the roof and bottom of the vehicle is the z direction in the three-dimensional coordinate system. Then the rotation axis 60 of the vehicle body 10 is parallel to the y direction, and the door 20 can rotate and move around the rotation axis 60 in the xz plane to realize the opening or closing operation of the door 20.

[0056] For example, Figure 3 and Figure 4 As shown, when the push rod 41 moves in the x direction toward the side away from the luggage compartment floor 11, the door 20 rotates counterclockwise around the rotation axis 60 in the xz plane, and the door 20 is closed; Figure 5 and Figure 6 As shown, when the push rod 41 moves in the x direction toward the side close to the luggage compartment floor 11 , the vehicle door 20 rotates clockwise around the rotation axis 60 in the xz plane, and the vehicle door 20 opens.

[0057] There is an installation cavity under the luggage compartment floor 11, and the first drive member 30 and the motion conversion mechanism 42 are completely located in the installation cavity, and the push rod 41 is partially located in the installation cavity, so that the first drive member 30 and the motion conversion mechanism 42 are hidden, and there is no need to install them in the cavity of the vehicle door 20, which reduces the weight of the vehicle door 20, reduces the overall load of the load-bearing mechanism 23, the hinge m21 and the hinge n22, and improves the overall stability, while not affecting the storage space and appearance in the luggage compartment. In addition, the first drive member 30 and the motion conversion mechanism 42 are installed in the installation cavity under the luggage compartment floor 11, which is easier to disassemble and assemble than installing them in the cavity of the vehicle door 20, and there is no need to disassemble and assemble by removing the door guard plate, which can save assembly and maintenance time of the production line. At the same time, the installation space of the installation cavity under the luggage compartment floor 11 is larger than the cavity of the vehicle door 20, and the arrangement flexibility and adaptability of the first drive member 30 and the motion conversion mechanism 42 are improved. The first driving member 30 is arranged in the installation cavity below the luggage compartment floor 11, which is convenient for arranging the wiring harness. The wiring harness does not need to be arranged in the cavity of the vehicle door 20, which can reduce the cost of the wiring harness and the wiring harness waterproof design.

[0058] It is understandable that during the process of opening or closing the vehicle door 20 , the first drive member 30 and the motion conversion mechanism 42 are always located on the luggage compartment floor 11 and will not rotate around the rotation axis 60 of the vehicle body 10 , thereby improving the stability of the vehicle door 20 driving.

[0059] In some embodiments, Figure 3As shown, the motion conversion mechanism 42 includes a first support member 421 and a rotating member 422 that are rotatably connected. The first support member 421 is suitable for being fixed on the vehicle body 10, one end of the rotating member 422 is fixedly connected to one end of the first driving member 30, and the other end of the rotating member 422 is fixedly connected to one end of the push rod 41.

[0060] Specifically, the first support member 421 and the rotating member 422 are both located on the vehicle body 10, such as on the luggage compartment floor 11 or the luggage compartment side panel of the vehicle body 10, and do not need to be installed in the cavity of the vehicle door 20, thereby reducing the weight of the vehicle door 20, reducing the overall load of the load-bearing mechanism 23, the hinge m21 and the hinge n22, and improving the overall stability.

[0061] The first support member 421 may be a bracket, and the first support member 421 is relatively fixed to the vehicle body 10. The first support member 421 may be fixed on the platinum bottom plate of the luggage compartment bottom plate 11, or may be fixed in the cavity below the luggage compartment bottom plate 11. The technicians in this field may set the installation position of the first support member 421 on the luggage compartment bottom plate 11 according to actual needs. The connection method between the first support member 421 and the luggage compartment bottom plate 11 may be screw connection, welding, riveting, etc. The rotating member 422 and the first support member 421 are rotatably connected by a rotating shaft 423, so that the rotating member 422 can rotate and move around the first support member 421 in the plane where the bottom plate of the luggage compartment bottom plate 11 is located, that is, the xy plane. When the driving device drives the first driving rod 301 to telescopically move in a linear direction, the rotating member 422 can be driven to rotate clockwise or counterclockwise in the xy plane, and then the push rod 41 can be driven to telescopically move in a linear direction in the x direction to realize the opening or closing operation of the vehicle door 20.

[0062] The middle position of the rotating member 422 is connected to the first supporting member 421 through the rotating shaft 423, and the two ends of the rotating member 422 are respectively fixedly connected to the first driven rod 302 and the push rod 41, such as by a spherical pair. For example, a ball head a and a ball head b are respectively arranged at the two ends of the rotating member 422, and a point ball socket a is arranged on the first driven rod 302, and the point ball socket a of the first driven rod 302 is connected to the ball head a of the rotating member 422 by a spherical pair; a point ball socket p and a point ball socket q are respectively arranged at the two ends of the push rod 41, and the point ball socket p of the push rod 41 close to the rotating member 422 is connected to the ball head b of the rotating member 422 by a spherical pair, and the point ball socket q at the other end of the push rod 41 is connected to the ball head arranged at the bottom end of the door 20 by a spherical pair.

[0063] In this example, the motion conversion mechanism 42 is used to convert the linear motion of the first driven rod 302 into the rotational motion of the door 20, so as to realize the opening and closing operations of the door 20, and the first driving member 30 is installed on the luggage compartment floor 11, so that the structural design of the motion conversion mechanism 42 is simplified, the assembly time is shortened, and the possibility of failure is reduced.

[0064] In some embodiments, the rotating member 422 is an arc-shaped connecting member, an L-shaped connecting member, or a C-shaped connecting member.

[0065] Specifically, the rotating member 422 may be an arc-shaped connecting member such as a semicircular connecting member, an L-shaped connecting member or a C-shaped connecting member. Those skilled in the art may set the specific shape of the rotating member 422 according to actual needs.

[0066] In some embodiments, Figure 3 As shown, the driving assembly further includes a second support member 50 , which is suitable for being fixed on the vehicle body 10 , and one end of the first driving member 30 away from the transmission mechanism 40 is hingedly or fixedly connected to the second support member 50 .

[0067] Specifically, the second support member 50 is located on the luggage compartment floor 11 and does not need to be installed in the cavity of the vehicle door 20, thereby reducing the weight of the vehicle door 20, reducing the overall load of the load-bearing mechanism 23, the hinge m21 and the hinge n22, and improving the overall stability. Among them, the second support member 50 can be a bracket, and the second support member 50 is relatively fixedly arranged with the vehicle body 10. The second support member 50 and the first support member 421 are both in the same plane, such as the first support member 421 and the second support member 50 are both fixed on the platinum bottom plate of the luggage compartment floor 11, or the first support member 421 and the second support member 50 are both fixed in the installation cavity below the luggage compartment floor 11. The second support member 50 and the first drive rod 301 can be fixedly connected in a spherical pair, or the second support member 50 is hinged to the first drive rod 301.

[0068] In some embodiments, Figures 1 to 3 As shown, the vehicle door 20 is provided with a hinge along the direction of the rotation axis 60 , and the push rod 41 of the transmission mechanism 40 is suitable for being connected to the hinge of the vehicle door 20 .

[0069] Specifically, a hinge is provided at the bottom of the door 20 along the direction of the rotation axis 60 thereof, and the hinge can be provided on the left or right side of the bottom of the door. The push rod 41 of the transmission mechanism 40 is fixedly connected to the hinge on the left or right side of the bottom of the door 20, such as by a spherical pair connection. For example, Figures 1 to 7As shown in FIG. 8 , the push rod 41 of the transmission mechanism 40 is connected to the hinge on the right side of the bottom end of the door 20; as shown in FIG. 8 , the push rod 41 of the transmission mechanism 40 is connected to the hinge on the left side of the bottom end of the door 20. The push rod 41 moves in a straight line direction, which can drive the bottom end of the door 20 to rotate around the rotation axis 60, thereby realizing the opening or closing operation of the door 20. The ball head of the hinge is fixed by a screw and is relatively fixed to the door 20, and can rotate and move with the rotation of the door 20 around the rotation axis 60. In this example, the opening or closing operation of the door can be realized by a set of first driving members 30 and the transmission mechanism 40, which simplifies the cost.

[0070] In some embodiments, the vehicle door 20 is provided with two hinges along the direction of the rotation axis 60, and there are two transmission mechanisms 40, wherein a push rod 41 of one transmission mechanism 40 is connected to one hinge of the vehicle door 20, and a push rod 41 of the other transmission mechanism 40 is connected to another hinge of the vehicle door 20.

[0071] Specifically, the vehicle door 20 is symmetrically provided with two hinges, such as hinge m21 and hinge n22, along the direction of the rotation axis 60, and the corresponding transmission mechanism 40 and first driving member 30 also have two; wherein, one first driving member 30 is connected to the hinge m21 of the vehicle door 20 through a corresponding push rod 41 of the transmission mechanism 40, and the other first driving member 30 is connected to the hinge n22 of the vehicle door 20 through a corresponding push rod 41 of the transmission mechanism 40. The layout of the first driving member 30 and the motion conversion mechanism 42 is more diversified, and the vehicle door 20 is controlled to be opened or closed by two first driving members 30 at the same time, so that the vehicle door 20 is more stably stressed, and the service life of the vehicle door 20 is improved. At the same time, it can also avoid the situation that the vehicle door 20 cannot be opened or closed due to the failure of a certain first driving member 30, and improve the safety of the vehicle door 20.

[0072] In some embodiments, the push rod 41 is disposed perpendicular to the rotation axis 60 , and the first driving member 30 is disposed parallel to or perpendicular to the rotation axis 60 .

[0073] Specifically, those skilled in the art can set the layout of the first driving member 30 according to actual needs. For example, Figures 3 to 6As shown, the first driving rod 301 and the first driven rod 302 of the first driving member 30 are arranged along the y direction, and the push rod 41 is arranged along the x direction. In this case, when the driving device is powered on and starts to work, the first driving rod 301 is driven to drive the first driven rod 302 to extend toward the side close to the motion conversion mechanism 42 in the y direction. Under the spherical surface effect formed by the point ball socket a and the ball head a, the rotating member 422 rotates clockwise around the rotating shaft 423 of the first supporting member 421 in the xy plane, and under the spherical surface effect formed by the ball head b and the point ball socket p, the push rod 41 is driven to move toward the side away from the vehicle door 20 in the x direction (i.e., retract into the vehicle body 10). Since the push rod 41 is not retractable, under the spherical surface effect formed by the ball head on the hinge m21 and the point ball socket q on the push rod 41, the vehicle door 20 is driven to rotate clockwise around the rotation axis 60 in the xz plane to realize the opening operation of the vehicle door 20.

[0074] When the first driving rod 301 drives the first driven rod 302 to retract in the y direction toward the side away from the motion conversion mechanism 42, under the side effect of the spherical surface composed of the ball socket a and the ball head a, the rotating member 422 rotates counterclockwise around the rotating shaft 423 of the first supporting member 421 in the xy plane, and drives the push rod 41 to move in the x direction toward the side close to the vehicle door 20 under the side effect of the spherical surface composed of the ball head b and the ball socket p. Since the push rod 41 is not retractable, under the side effect of the spherical surface composed of the ball head on the hinge m21 and the ball socket q on the push rod 41, the vehicle door 20 is driven to rotate counterclockwise around the rotation axis 60 in the xz plane to realize the closing operation of the vehicle door 20.

[0075] For example Figure 7 As shown, the first driving rod 301 and the first driven rod 302 of the first driving member 30 are arranged along the x direction, and the push rod 41 is arranged along the x direction. In this case, when the driving device drives the first driving rod 301 to drive the first driven rod 302 to extend in the x direction toward the side close to the vehicle door 20, the motion conversion mechanism 42 rotates clockwise in the xy plane, drives the push rod 41 to move in the x direction toward the side away from the vehicle door 20, and then drives the vehicle door 20 to rotate clockwise in the xz plane to achieve the opening operation of the vehicle door 20. When the first driving rod 301 drives the first driven rod 302 to retract in the x direction toward the side away from the vehicle door 20, the motion conversion mechanism 42 rotates counterclockwise in the xy plane, drives the push rod 41 to move in the x direction toward the side close to the vehicle door 20, and then drives the vehicle door 20 to rotate counterclockwise in the xz plane to achieve the closing operation of the vehicle door 20.

[0076] In other embodiments, Fig. 9As shown, the transmission mechanism 40 includes a second follower rod 43, one end of which is movably connected to the first driving member 30, and the other end of the second follower rod 43 is suitable for being fixedly connected to the vehicle door 20, and the first driving member 30 is used to drive the second follower rod 43 to telescopically move along its axial line.

[0077] Specifically, the first driving member 30 may be a driving rod, one end of the second driven rod 43 is movably connected to the first driving rod 301 of the first driving member 30, and the other end of the second driven rod 43 is fixedly connected to the hinge of the vehicle door 20 in a spherical pair. The driving device drives the first driving rod 301 to drive the second driven rod 43 to move along its axial line to achieve the opening or closing operation of the vehicle door 20. During the process of opening or closing the vehicle door 20, the first driving member 30 is always located in the vehicle body 10 and does not rotate around the rotation axis 60 of the vehicle body 10.

[0078] In this example, the first follower rod 302, the motion conversion mechanism 42, the push rod 41 and other structures are replaced by the second follower rod 43, so that the drive control method of the vehicle door 20 is simpler and the control cost is lower; and the first drive member 30 is completely located in the vehicle body 10, and the second follower rod 43 is partially located in the vehicle body 10, which reduces the weight of the vehicle door 20 and the overall load of the load-bearing mechanism 23, hinge m21, and hinge n22 at the vehicle door 20, thereby improving the overall stability and facilitating disassembly and assembly.

[0079] It should be noted that two second driven rods 43 can be provided, and two first driving members 30 can also be provided. The opening or closing of the vehicle door 20 is controlled by a dual-drive method, and the driving stability and safety of the vehicle door 20 are high.

[0080] In other embodiments, Fig. 9 As shown, the second driven rod 43 is adapted to be arranged to intersect with the rotation axis 60 of the vehicle door 20 .

[0081] Specifically, the vehicle door 20 is a vehicle tailgate, and the second driven rod 43 is arranged to intersect with the rotation axis 60 of the vehicle door 20, preferably arranged vertically, so that the second driven rod 43 can control the movement of the bottom of the vehicle door 20 along the x direction to realize the opening or closing operation of the top of the vehicle door 20.

[0082] A second aspect of the present invention provides a vehicle, wherein the vehicle comprises the door drive assembly of the vehicle described in any embodiment of the present application.

[0083] The vehicle provided in the embodiment of the present application can be a pure electric vehicle or a hybrid electric vehicle.
