[0060] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0061] Reference Figure 1 and Figure 2 , an embodiment of the present application provides a motion mechanism, the motion mechanism comprising:

[0062] A base 11, the base 11 is suitable for connecting with the first component;

[0063] A connecting rod assembly 2, the connecting rod assembly 2 comprising an active rod 21, a driven rod 22, a mounting seat 23 and a driving member 24, one end of the active rod 21 and one end of the driven rod 22 are connected to the base 11, the other end of the active rod 21 and the other end of the driven rod 22 are connected to the mounting seat 23, and the mounting seat is suitable for connecting with a second component;

[0064] The driving member 24 is connected to the active rod 21 and is used to drive the active rod 21 to rotate, so as to drive the second component to move relative to the first component;

[0065] The active rod 21 can drive the driven rod 22 and the mounting seat 23 to rotate, so that the mounting seat moves relative to the base.

[0066] Specifically, the vehicle to which the motion mechanism is applied has a length dimension, a width dimension, and a height dimension. The length dimension of the vehicle is the dimension of the vehicle in the length direction. Figure 1 and attached Figure 2 The width dimension of the vehicle is the dimension of the vehicle in the width direction. The width dimension of the vehicle can be attached Figure 1 and attached Figure 2 The height dimension of the vehicle is the dimension of the vehicle in the height direction. The height dimension of the vehicle can be the Y direction of the vehicle. Figure 1 and attached Figure 2 In the Z direction, the X direction, Y direction and Z direction are perpendicular to each other.

[0067] In one embodiment, the first component may be a vehicle body, and the second component may be a door body 32. The door body 32 and the connecting seat 33 form a door assembly 3. The mounting seat 23 is used to install the door assembly 3. The active rod 21 can drive the driven rod 22 and the mounting seat 23 to rotate so that the door body 32 can switch between an open position and a closed position relative to the vehicle body.

[0068] One end of the active rod 21 and one end of the driven rod 22 are connected to the base 11 at intervals, and the other end of the active rod 21 and the other end of the driven rod 22 are connected to the mounting seat 23 at intervals, so that the base 11, the active rod 21, the driven rod 22 and the mounting seat 23 form a four-bar structure, which improves the stability of the connecting rod assembly 2 in driving the door body 32 to move.

[0069] Furthermore, the driving member 24 can flexibly control the rotation angle of the active rod 21, so that the opening and closing process of the door body 32 is accurately controlled, and the door body 32 can hover at any position during the door opening and closing process, thereby improving the flexibility of the door body 32 during the door opening and closing process.

[0070] The motion mechanism provided in the embodiment of the present application includes: a base 11; a connecting rod assembly 2, the connecting rod assembly 2 includes an active rod 21, a driven rod 22, a mounting seat 23 and a driving member 24, one end of the active rod 21 and one end of the driven rod 22 are connected to the base 11, and the other end of the active rod 21 and the other end of the driven rod 22 are connected to the mounting seat 23; the driving member 24 is connected to the active rod 21, and is used to drive the active rod 21 to rotate, so as to drive the second component to move relative to the first component; the active rod 21 can drive the driven rod 22 and the mounting seat 23 to rotate, so that the mounting seat moves relative to the base, thereby improving the stability of the second component during the movement relative to the first component.

[0071] In one embodiment, both ends of the active rod 21 and the driven rod 22 are movably connected to the base 11 and the mounting seat 23 respectively. For example, one end of the active rod 21 and the driven rod 22 is connected to the base 11 by a rotating pair or a ball head fit, and the other end of the active rod 21 and the driven rod 22 is connected to the mounting seat 23 by a rotating pair or a ball head fit.

[0072] Optionally, the driving member 24 can drive the active rod 21 to rotate in a plane perpendicular to the length direction of the vehicle.

[0073] Specifically, the active rod 21 rotates in a plane perpendicular to the length direction of the vehicle, that is, the active rod 21 rotates in the YZ plane. On the one hand, it can facilitate the door body 32 to move away from the motion mechanism and open upward, or to facilitate the door body 32 to move close to the motion mechanism and close downward. On the other hand, it can avoid the active rod 21 occupying a large space in the length direction of the motion mechanism, thereby improving the compactness and layout flexibility of the motion mechanism.

[0074] Alternatively, see Figure 6 , the base 11, the active rod 21, the driven rod 22 and the mounting seat 23 form a multi-link structure;

[0075] During the movement of the multi-link structure, the mounting seat 23 is parallel to the base 11 .

[0076] In this embodiment, the vehicle body includes a vehicle body side panel 1, and a base 11 is arranged on the vehicle body side panel 1; the base 11, the active rod 21, the driven rod 22 and the mounting seat 23 form a four-bar linkage with a parallelogram structure, so that when the active rod 21 drives the driven rod 22 and the mounting seat 23 to rotate together, the mounting seat 23 always remains parallel to the vehicle body side panel 1, thereby ensuring the stability of the door body 32 during opening and closing.

[0077] It is understandable that during the movement of the multi-link structure, the surface of one side of the mounting seat 23 used to connect to the vehicle door remains in the same orientation and is always parallel, thereby ensuring the stability of the door body 32 during opening and closing.

[0078] Alternatively, see Figure 6 and Figure 7 The base 11 has a first connection structure 111 and a second connection structure 112, and the mounting seat 23 has a third connection structure 231 and a fourth connection structure 232;

[0079] One end of the active rod 21 is rotatably connected to the first connecting structure 111, one end of the driven rod 22 is rotatably connected to the second connecting structure 112, the other end of the active rod 21 is rotatably connected to the third connecting structure 231, and the other end of the driven rod 22 is rotatably connected to the fourth connecting structure 232.

[0080] Specifically, see Figure 6 When viewed along the length direction of the vehicle, the first connecting structure 111, the second connecting structure 112, the third connecting structure 231 and the fourth connecting structure 232 form four corners of a parallelogram connecting rod structure.

[0081] The door body 32 is connected to the mounting seat 23. For example, the door body 32 is connected to the mounting seat 23 via a Y-axis pin, so that the door body 32 can remain parallel to the vehicle body side panel 1, ensuring the posture of the door body 32 during the door opening and closing process.

[0082] Optionally, the first connection structure 111 is located at one side of the base 11 in a first direction, and the third connection structure 231 is located at one side of the mounting base 23 in a second direction, and the first direction is opposite to the second direction.

[0083] In this embodiment, see Figure 6 The first connection structure 111 can be located on the upper side of the base 11; the third connection structure 231 is located on the lower side of the mounting seat 23 close to the base 11, and the mounting seat 23 is located on the lower side of the door body, so that the door body is lifted upward when opening to prevent the door body from colliding with the ground.

[0084] Alternatively, see Figure 6 The base 11 is provided with a first protrusion 113 , and the first connecting structure 111 is located at an end of the first protrusion 113 away from the base 11 .

[0085] Specifically, since the active rod 21 is the active component that drives the four-bar structure formed by the base 11, the active rod 21, the driven rod 22 and the mounting seat 23 to move, the active rod 21 is separated from the base 11 by a distance through the first protrusion 113. This makes it easier for the active rod 21 to drive the door body 32 to move, and the door body 32 occupies less space in a closed state, thereby avoiding interference of the base 11 with the opening and closing of the door body 32.

[0086] Alternatively, see Figure 6 , the first connecting structure 111 is located at the top of the base 11.

[0087] Specifically, when the active rod 21 drives the door body 32 to move, since the first connecting structure 111 is located at the top of the base 11, one end of the active rod 21 is rotated and connected to the first connecting structure 111 to increase the installation height of the active rod 21, thereby raising the minimum height of the door body 32, ensuring that the door body 32 does not hit the ground when being lifted upward during opening.

[0088] Alternatively, see Figure 6 A second protrusion 114 is provided on the base 11 , and the second connecting structure 112 is located on an end of the second protrusion 114 away from the base 11 .

[0089] The protrusion length of the first protrusion 113 is greater than the protrusion length of the second protrusion 114 .

[0090] Specifically, the setting of the second protrusion 114 can avoid the interference of the driven rod 22 with the base 11 when it is active; and in the width direction of the vehicle, the protrusion length of the first protrusion 113 is greater than the protrusion length of the second protrusion 114, and the active rod 21 can be set on the side of the driven rod 22 away from the base 11, ensuring the convenience of connection between the active rod 21 and the door body 32.

[0091] Alternatively, see Figure 3 and Figure 4 The driving member 24 includes a support rod 242 , a first end of the support rod 242 is movably connected to the base 11 , and a second end of the support rod 242 is connected to the active rod 21 .

[0092] Specifically, the support rod 242 and the active rod 21 are connected to form a fork arm structure, so that the door body 32 can be driven to move and hover through the fork arm structure, thereby ensuring the stability of the door body 32 during the opening process.

[0093] Optionally, the first end of the support rod 242 slides relative to the base 11. In this embodiment, the first end of the support rod 242 can be connected to a slide groove on the base 11 through a slider, so that when the first end of the support rod 242 slides relative to the base 11, the active rod 21 is pushed to rotate.

[0094] Optionally, the base 11 has a first connection structure 111 and a second connection structure 112, one end of the active rod 21 is rotatably connected to the first connection structure 111, and one end of the driven rod 22 is rotatably connected to the second connection structure 112;

[0095] The direction from the first connecting structure 111 to the second connecting structure 112 is parallel to the sliding direction of the first end of the support rod 242, so that the door body 32 can move along the sliding direction parallel to the first end of the support rod 242. For example, when the first end of the support rod 242 slides vertically, the vertical opening and closing of the door body 32 is ensured.

[0096] Optionally, the driving member 24 includes a hydraulic rod 241, and the hydraulic rod 241 is telescopically arranged on the base 11;

[0097] The hydraulic rod 241 is rotatably connected to the first end of the support rod 242 , and the hydraulic rod 241 can drive the support rod 242 to slide.

[0098] In this embodiment, the hydraulic rod 241 can be telescopically movable on the base 11 under the drive of hydraulic pressure, so as to drive the support rod 242 to slide by adjusting the stroke of the hydraulic rod 241, thereby adjusting the side opening distance and rotation angle of the door body 32, and preventing the door body 32 from sinking.

[0099] In another embodiment, the driving member 24 includes a motor and a support rod 242, and the motor output shaft replaces the hydraulic rod, which can also realize the movement of the connecting rod assembly 2, thereby driving the door body 32 to open sideways and rotate.

[0100] Optionally, the base 11 has a slide groove, and the hydraulic rod 241 is telescopically arranged in the slide groove.

[0101] In this embodiment, the base 11 may have a slide groove extending along the height direction of the vehicle, and the hydraulic rod 241 may be telescopically arranged in the slide groove to provide guidance for the extension and retraction of the hydraulic rod 241 through the slide groove, thereby ensuring the position accuracy of the hydraulic rod 241 when it moves.

[0102] Furthermore, the distance between the mounting hole of the active rod 21 on the mounting seat 23 and the mounting hole of the driven rod 22 on the mounting seat 23 is smaller than the distance between the mounting holes at both ends of the active rod 21, that is, the distance between the third connecting structure 231 and the fourth connecting structure 232 is smaller than the length of the active rod 21, so as to reduce the design size of the mounting seat 23 and simplify the design space of the vehicle body structure.

[0103] Optionally, a first bevel gear 25 is provided at the other end of the active rod 21, and a second bevel gear 31 suitable for connecting with the second component is provided on the mounting seat 23, and the second bevel gear 31 is transmission connected to the first bevel gear 25 so that when the active rod 21 rotates in a plane perpendicular to the length direction of the vehicle, the second component can rotate in a plane perpendicular to the width direction of the vehicle.

[0104] Specifically, the transmission cooperation between the second bevel gear 31 and the first bevel gear 25 forms a rotation reversing mechanism between the second component of the connecting rod assembly 2 and the door body 32, specifically converting the rotation of the active rod 21 into the rotation of the door body 32, so that when the door body 32 is opened, the door body 32 can rotate while translating obliquely upward, thereby improving the control accuracy of the posture of the door body 32 when opening and closing the door.

[0105] In one embodiment, the active rod 21 and the first bevel gear 25 can be integrally formed to facilitate the structural forming of the connecting rod assembly 2; in another embodiment, the first bevel gear 25 can also be detachably connected to the active rod 21 to achieve steering ratio adjustment of the rotation reversing mechanism while flexibly replacing the first bevel gear 25.

[0106] Alternatively, see Figure 5 , the mounting seat 23 has an assembly cavity;

[0107] The second bevel gear 31 is located in the assembly cavity together with the first bevel gear 25 .

[0108] Specifically, the second bevel gear 31 can be connected to the mounting base 23 by a pin or riveting to maintain synchronous movement with the mounting base 23 in the axial direction of the second bevel gear 31; and the active rod 21 can drive the first bevel gear 25 to rotate when rotating. The transmission cooperation between the second bevel gear 31 and the first bevel gear 25 can realize the joint rotation of the door body 32 and the second bevel gear 31 when the first bevel gear 25 rotates, so that the door body 32 can avoid the door hole on the door body 32.

[0109] Optionally, the transmission ratio of the first bevel gear 25 and the second bevel gear 31 ranges from 0.8 to 1.2.

[0110] Specifically, by adjusting the transmission ratio on the first bevel gear 25 and the second bevel gear 31, the transmission ratio can be changed specifically by changing the gear tooth parameters on the first bevel gear 25 and the second bevel gear 31, so that the rotation angle and the unfolding posture of the door body 32 can be quickly adjusted, thereby improving the opening and rotation flexibility of the door body 32.

[0111] The embodiment of the present application also provides a vehicle door structure, which includes a door body 32 and the above-mentioned motion mechanism;

[0112] The second component is the door body 32 , the mounting seat is connected to the door body 32 , and the base is suitable for being connected to a vehicle body.

[0113] In this embodiment, the first component can be a vehicle body, the second component can be a door body 32, the mounting seat 23 is used to install the door body 32, and the active rod 21 can drive the driven rod 22 and the mounting seat 23 to rotate so that the door body 32 can switch between an open position and a closed position relative to the vehicle body.

[0114] In one embodiment, the door structure includes a vehicle body side panel 1, on which the base 11 is provided, the door body 32 is connected to the mounting seat 23, and the active rod 21 can drive the driven rod 22 and the mounting seat 23 to rotate together so that the door body 32 can switch between an open position and a closed position.

[0115] Specifically, a door opening is provided on the vehicle body side panel 1 , and the base 11 is connected to the side of the door opening so that the active rod 21 drives the door body 32 to switch between the open position and the closed position under the drive of the driving member 24 .

[0116] Taking the opening of the door body 32 as an example, when the active rod 21 rotates in the YZ plane to drive the door body 32 away from the door structure and open upward, the door body 32 is pushed away from the vehicle body side panel 1 in the Y-axis direction and unfolded, and at the same time, the door body 32 is lifted to a certain height along the Z-axis direction.

[0117] Optionally, a rotation shaft is provided on the base 11, and the active rod 21 rotates around the rotation shaft, and the axis of the rotation shaft is suitable for extending along the front-rear direction of the vehicle.

[0118] In this embodiment, the axis of the rotating shaft can be parallel to the front-to-back direction of the vehicle, or the axis of the rotating shaft can have a certain angle with the front-to-back direction of the vehicle. For example, when the angle between the axis of the rotating shaft and the front-to-back direction of the vehicle is in the range of 0-30°, the axis of the rotating shaft can be considered to extend along the front-to-back direction of the vehicle, so as to facilitate the rotation of the active rod 21 around the axis extending in the front-to-back direction of the vehicle.

[0119] Optionally, the axis of the rotating shaft is suitable to be parallel to the front-rear direction of the vehicle, so that the active rod 21 can only rotate around the axis in the front-rear direction of the vehicle, avoiding the swing of the door body 32 in the front-rear direction of the vehicle and ensuring the stability of the door body 32 during the opening and closing process.

[0120] Alternatively, see Figures 3 to 5 , the door structure also includes a connecting seat 33;

[0121] The connecting seat 33 is used to connect the door body 32 and the mounting seat 23 .

[0122] Specifically, when the second bevel gear 31 and the first bevel gear 25 are in transmission cooperation, the rotation of the active rod 21 can drive the door body 32 and the connecting seat 33 to rotate in a plane perpendicular to the width direction of the vehicle through the second bevel gear 31 and the first bevel gear 25. Specifically, the connecting seat 33 and the mounting seat 23 are connected through a rotating pair.

[0123] Alternatively, see Figure 6 One end of the active rod 21 is connected to the top of the base 11, and the other end of the active rod 21 is connected to the bottom of the door body 32, so that the door body is lifted up during opening to prevent the door body from colliding with the ground. Specifically, the other end of the active rod 21 is connected to the bottom of the door body 32.

[0124] In this embodiment, one end and the other end of the active rod 21 are connected diagonally up and down, which can increase the opening and closing range of the door body 32, and ensure the maximum side opening distance and lifting space of the door body 32 when the door body 32 and the connecting seat 33 rotate together, further adapting to the opening and closing of different door body thicknesses.

[0125] Optionally, the active rod 21 rotates at an angle ranging from 0 to 150°, and the door body 32 rotates at an angle ranging from 0 to 90°.

[0126] Specifically, the rotation angle of the active rod 21 can control the side opening and lifting height of the door body 32, and at the same time adjust the rotation angle of the door body 32; for example, when the rotation angle of the active rod 21 increases, the side opening and lifting height of the door body 32 and the rotation angle of the door body 32 can be increased.

[0127] In one embodiment, the transmission ratio of the first bevel gear 25 and the second bevel gear 31 is 1:1, and when the active rod 21 rotates by 90°, the door body 32 can be opened and lifted, and the door body 32 rotates by 90°.

[0128] In order to increase the opening and lifting distance of the door body 32, the rotation angle of the active rod 21 can be set to be greater than 90°, for example, the rotation angle of the active rod 21 can reach 100°, 120° or 135°.

[0129] Optionally, the driving member 24 includes a support rod 242, a first end of the support rod 242 slides along the height direction of the vehicle relative to the base 11, and the second end of the support rod 242 is connected to the active rod 21, so that the door body 32 can be driven by the active rod 21 to move along the sliding direction parallel to the first end of the support rod 242. For example, when the first end of the support rod 242 is along the height direction of the vehicle, the opening and closing of the door body 32 along the height direction of the vehicle is ensured.

[0131] The first component is a vehicle body, and the door body moves relative to the vehicle body so that the door body switches between an open position and a closed position.

[0132] In this embodiment, in the door structure of the vehicle body structure, the door structure includes a vehicle body side panel 1, a base 11 is provided on the vehicle body side panel 1, and the base is connected to the vehicle body; a connecting rod assembly 2 and a door body 32, the connecting rod assembly 2 includes an active rod 21, a driven rod 22, a mounting seat 23 and a driving member 24, one end of the active rod 21 and one end of the driven rod 22 are connected to the base 11, the other end of the active rod 21 and the other end of the driven rod 22 are connected to the mounting seat 23, and the mounting seat is connected to the door body 32; the driving member 24 is connected to the active rod 21 and is used to drive the active rod 21 to rotate; the active rod 21 can drive the driven rod 22 and the mounting seat 23 to rotate, so that the door body 32 can switch between the open position and the closed position, thereby improving the stability of the door body 32 of the vehicle during the opening and closing process.
