Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a hinge, a door assembly and a vehicle. Background Art

[0002] The hinge is an important part of the car, which is mainly installed between the car body and the back door to support and rotate the car back door. In the related art, the back door of the car is a top and bottom door, and the hinge controls the rotation of the top and bottom door to open and close the top and bottom door.

[0003] However, since the hinge controls the opening and closing of the top and bottom doors by rotating, when the top and bottom doors are closed, the upper back door blocks the lower back door. When opening the door, you need to open the upper back door first before opening the lower back door, otherwise the upper back door will block the opening of the lower back door, causing the upper and lower back doors to collide. When closing the door, you need to close the lower back door first before closing the upper back door, otherwise the upper back door will block the closing of the lower back door, causing the upper and lower back doors to collide.

[0004] Therefore, the top and bottom doors in the related art are restricted by the movement of the hinges, which means that the upper and lower back doors in the top and bottom doors need to strictly follow the opening and closing sequences, resulting in the door opening and closing sequences cannot be adjusted according to actual conditions. The operation of opening and closing the doors is greatly limited and cannot meet the needs of some special scenarios. Summary of the invention

DETAILED DESCRIPTION

[0067] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0068] In the description of the subsequent embodiments, the word "connected" or "connected" should be understood to mean direct connection, indirect connection, or integral molding.

[0069] This application provides a hinge 1, see Figure 1 and Figure 2 .

[0070] The hinge 1 includes a first connecting member 11, a second connecting member 12 and a transmission mechanism 13. The hinge 1 can be applied to a door 2 in a vehicle, and the door 2 can refer to a side door in the vehicle, such as a co-pilot's door 2, a main driver's door 2, a rear seat door 2, etc., or a back door of a trunk of a vehicle. In the present embodiment, the hinge 1 is mainly applied to a back door for explanation, and is mainly for a vehicle whose back door is a sky and earth door. The sky and earth door refers to a back door having an upper back door and a lower back door. When opening and closing, both doors will move, and by connecting and cooperating the upper back door and / or the lower back door with the hinge 1 provided in the present application, the upper and lower back doors can be opened and closed independently and freely, and there will be no interference between the upper and lower back doors, thereby avoiding the limitation of opening and closing the door. Of course, in other embodiments, the hinge 1 can also be applied to a side door or a back door with only one door, which is not limited here.

[0071] Among them, the first connecting member 11 is used to connect with the vehicle body 3, and the second connecting member 12 is used to connect with the vehicle door 2. The transmission mechanism 13 is movably connected with the first connecting member 11 and the second connecting member 12 respectively, and the transmission mechanism 13 is used to limit the motion trajectory of the second connecting member 12 relative to the first connecting member 11 so that the second connecting member 12 has a first motion state and a second motion state. Specifically, the transmission mechanism 13 is rotatably arranged on the first connecting member 11, and the side of the transmission mechanism 13 away from the first connecting member 11 is rotatably connected with the second connecting member 12, so that the first connecting member 11 and the second connecting member 12 are connected through the transmission mechanism 13, and the movement of the transmission mechanism 13 can be transmitted to the second connecting member 12, and the first connecting member 11 can provide support for the movement and installation of the transmission mechanism 13 and the second connecting member 12. The transmission mechanism 13 is used to drive the second connecting member 12 to perform the first movement and the second movement. It should be noted that the transmission mechanism 13 can drive the second connecting member 12 to perform the first movement and the second movement, which means that the transmission mechanism 13 can drive the second connecting member 12 to perform the first movement and the second movement. The transmission mechanism 13 drives the second connecting member 12 to perform the first movement mainly to enable the back door connected to the second connecting member 12 to perform the first movement, to avoid the other back door, to enable the two back doors to open and close independently, and to improve the flexibility of opening and closing of the back door. The first movement refers to the connecting rod movement, and the second movement refers to the rotational movement. The connecting rod movement refers to the movement formed based on the connection and matching relationship of the various components of the connecting rod mechanism. The connecting rod mechanism can be a four-bar linkage, a five-bar linkage, etc. Correspondingly, the first movement state refers to the connecting rod movement state, and the second movement state refers to the rotational movement state.

[0072] In detail, the transmission mechanism 13 drives the second connecting member 12 to perform connecting rod movement and rotational movement, so that the vehicle door 2 connected to the second connecting member 12 can perform connecting rod movement and rotational movement. The vehicle door 2 performs connecting rod movement driven by the transmission mechanism 13, so that the vehicle door 2 can move away from or approach another vehicle door 2 that is not connected to the second connecting member 12 in a linear direction, thereby achieving the avoidance or closing of the two vehicle doors 2. The vehicle door 2 performs rotational movement driven by the transmission mechanism 13, thereby achieving the opening or closing of the vehicle door 2. Regardless of opening or closing the vehicle door 2, the hinge 1 can independently drive the vehicle door 2 to perform connecting rod movement and rotational movement without being affected by the other vehicle door 2. There is no order for opening and closing the vehicle door 2, thereby improving the operational flexibility of the hinge 1 in cooperating with the vehicle door 2 to open and close, thereby improving the applicability of the vehicle door assembly in different environments. Specifically, first, the vehicle body 3 is connected to the hinge 1 by using the first connecting member 11 to provide support for the subsequent movement of the hinge 1, and one of the doors 2 in the door assembly is connected to the hinge 1 by using the second connecting member 12, and the movement of the transmission mechanism 13 is transmitted to the door 2, thereby driving the door 2 to move; secondly, the transmission mechanism 13 is used to drive the second connecting member 12 to perform connecting rod movement and rotational movement, and then drive the door 2 to perform connecting rod movement, so that the door 2 can close with or move away from the other door 2, thereby achieving the closing or avoidance of the two doors 2; then, the transmission mechanism 13 is used to drive the second connecting member 12 to perform rotational movement, and then drive the door 2 to perform rotational movement, so that the door 2 can be opened or closed.

[0073] In some embodiments, the transmission mechanism 13 includes a switching assembly, which is used to switch the second connection member 12 between the first motion state and the second motion state, and then use the second connection member 12 to drive the door 2 to switch between the first motion state and the second motion state, so as to achieve the avoidance and rotation of the door 2. The first motion is mainly used to achieve the avoidance of the door 2, and the second motion is mainly used to achieve the rotation of the door 2.

[0074] Furthermore, the switching assembly includes a first switching assembly 14, which is disposed on the first connecting member 11 and is used to switch the second connecting member 12 from the first motion state to the second motion state. Specifically, when the second connecting member 12 drives the vehicle door 2 to make the first motion to a position sufficient to avoid the other vehicle door, the first switching assembly 14 will switch the second connecting member 12 to make the second motion, so that the second connecting member 12 drives the vehicle door 2 to make the second motion, thereby realizing the opening of the vehicle door 2. During this process, the other vehicle door can be in the open state or in the closed state, which will not affect the opening of the vehicle door 2, and there is no need to distinguish the opening order of the two vehicle doors.

[0075] Furthermore, the transmission mechanism 13 includes a first rotating assembly 131, which is rotatably connected to the first connecting member 11 and the second connecting member 12, respectively, so that the first rotating assembly 131 can rotate relative to the first connecting member 11 based on the supporting force provided by the first connecting member 11, so that the first rotating assembly 131 can drive the second connecting member 12 to move. The first switching assembly 14 cooperates with the first rotating assembly 131 to switch the second connecting member 12 from the first motion state to the second motion state.

[0076] In some embodiments, the switching component includes a second switching component 133, which is disposed on the first connecting member 11 and is used to switch the second connecting member 12 from the second motion state to the first motion state.

[0077] In some embodiments, the transmission mechanism 13 includes a first rotating component 131 and a second rotating component 132, the first rotating component 131 and the second rotating component 132 are rotatably connected to the first connecting member 11 and the second connecting member 12, respectively, and the second rotating component 132 is rotatably connected to the first connecting member 11 and the second connecting member 12, respectively. Specifically, the first rotating component 131 and the second rotating component 132 are rotatably connected to the first connecting member 11 and the second connecting member 12, respectively, the first connecting member 11 provides support for the first rotating component 131 and the second rotating component 132, and the second connecting member 12 is a driven member driven by the first rotating component 131 and the second rotating component 132, so that the first connecting member 11, the second connecting member 12, the first rotating component 131 and the second rotating component 132 form a linkage mechanism, which is specifically a four-bar linkage. When the linkage mechanism is a four-bar linkage, the linkage motion of the second connecting member 12 refers to the motion formed based on the matching relationship of the components of the four-bar linkage, which can be a translation or a composite motion formed by translation and rotation. Translation can form linear motion or approximate linear motion, and compound motion can form linear motion or approximate linear motion. For example, when the linkage mechanism is a four-bar linkage, the first rotating component 131 drives the second connecting member 12 and the second rotating component 132 to move when the first rotating component 131 moves, and their movements are synchronous. At this time, the movement trajectory of the second connecting member 12 is determined, and the movement of the second connecting member 12 is a connecting rod movement.

[0078] Furthermore, the transmission mechanism 13 includes a switching assembly, and the switching assembly includes a first switching assembly 14 and a second switching assembly 133. The first switching assembly 14 is used to switch the second connecting member 12 from the first motion state to the second motion state, and the second switching assembly 133 is used to switch the second connecting member 12 from the second motion state to the first motion state. By using the first switching assembly 14 and the second switching assembly 133, the second connecting member 12 is switched back and forth between the first motion state and the second motion state, and the second connecting member 12 drives the door 2 to switch back and forth between avoidance and rotation, thereby realizing the independent opening and closing of the door 2.

[0079] In some embodiments, one side of the first rotating component 131 is rotationally connected to the first connecting member 11, and the other side is rotationally connected to the second connecting member 12. One side of the second rotating component 132 is rotationally connected to the first connecting member 11, and the other side is rotationally connected to the second connecting member 12. Among them, the movement process of the second connecting member 12 includes a first movement state and a second movement state. When the second connecting member 12 is in the first movement state, the first rotating component 131 and the second rotating component 132 jointly drive the second connecting member 12 to perform a connecting rod movement, and the second connecting member 12 drives the vehicle door 2 to perform a connecting rod movement synchronously. At this time, the connecting rod movement of the vehicle door 2 is mainly used to avoid another vehicle door 2, so as to avoid collision between the two vehicle doors 2 during subsequent rotation. When the second connecting member 12 is in the second movement state, the first rotating component 131 abuts against the first switching component 14, and the second rotating component 132 drives the second connecting member 12 to perform a rotational movement. Specifically, when the first rotating assembly 131 and the second rotating assembly 132 drive the connecting rod of the second connecting member 12 to move to a specified position, the door 2 connected to the second connecting member 12 will avoid the other door 2, and the first rotating assembly 131 will also abut against the first switching assembly 14, thereby limiting the subsequent continued movement of the first rotating assembly 131 to avoid interfering with the subsequent rotational movement of the second connecting member 12. The second rotating assembly 132 continues to rotate, driving the second connecting member 12 to rotate, and realizing the opening and closing of the door 2, and the opening and closing is determined by the rotation direction.

[0080] It should be noted that the door 2 and the other door 2 mentioned here, the two doors 2 avoid each other, mainly refers to the hinge 1 being set on the top and bottom doors. That is, at least one of the back doors, such as the lower back door, is provided with the hinge 1. When the top and bottom doors are in a closed state, the end of the upper back door facing the lower back door will cover the end of the lower back door, thereby ensuring the aesthetic effect after the two doors are closed and eliminating the gap between the two doors. At this time, if the top and bottom doors need to be opened, the traditional way is to first open the back door covering the outside, that is, the upper back door, and then open the lower back door to avoid interference between the two doors. In this embodiment, the lower back door is driven by the hinge 1 to make a connecting rod movement, so that the lower back door can move downward to move away from the upper back door. At this time, the connecting rod movement is a downward linear motion or an approximately linear motion, so that a certain distance is generated between the upper and lower back doors. The distance only needs to ensure that the lower back door does not collide with the upper back door when rotating. The hinge 1 then drives the lower back door to rotate, that is, the independent opening of the lower back door is completed. The closing of the lower back door is opposite, that is, the lower back door is first controlled to rotate by the hinge 1, and then the lower back door is controlled to move the connecting rod.

[0081] It should also be noted that the first rotating component 131, the second rotating component 132, the second connecting member 12 and the first connecting member 11 together constitute a four-bar linkage structure, which can enable the second connecting member 12 to switch between connecting rod movement and rotational movement. When switching between connecting rod movement and rotational movement, the four-bar linkage structure has a dead point, which is used to limit the first rotating component 131 from continuing to rotate with the second rotating component 132, and make the first rotating component 131 and the second rotating component 132 drive the second connecting member 12 to move coaxially with the axis, ensuring that the second rotating component 132 can continue to drive the second connecting member 12 to rotate on its own.

[0082] In some embodiments, the transmission mechanism 13 further includes a second switching component 133, which is rotatably disposed on the first connecting member 11 and is located between the first rotating component 131 and the second rotating component 132 to transmit the movement of the first rotating component 131 and the second rotating component 132. The second switching component 133 is provided to facilitate ensuring the synchronization of the movement of the first rotating component 131 and the second rotating component 132. In addition, the second switching component 133 plays a role in transmitting the movement of the second rotating component 132 to the first rotating component 131 during the subsequent movement of the second connecting member 12 from the second position to the first position, so that the first rotating component 131 can cross the dead point and switch from the abutting state to a rotational movement synchronized with the movement of the second rotating component.

[0083] In some embodiments, the first switching component 14 includes a limiting protrusion 141. The limiting protrusion 141 is provided on the first connecting member 11. When the second connecting member 12 is in the transition position, the limiting protrusion 141 abuts against the first rotating component 131 to prevent the first rotating component 131 from moving. The rotation axis where the first rotating component 131 is rotationally connected with the second connecting member 12 is colinear with the rotation axis where the second rotating component 132 is rotationally connected with the first connecting member 11, so that when the second rotating component 132 continues to rotate, the first rotating component 131 abuts against the limiting protrusion 141, resulting in it being unable to continue to cooperate with the second rotating component 132 to continue to drive the second connecting member 12 to perform connecting rod movement. At the same time, at this time, the rotation axis where the first rotating component 131 is rotationally connected with the second connecting member 12 is colinear with the rotation axis where the second rotating component 132 is rotationally connected with the first connecting member 11, so that the second rotating component 132 continues to rotate, and can drive the second connecting member 12 to rotate around the rotation axis where the second rotating component 132 is rotationally connected, thereby realizing the switching from the first motion state to the second motion state. It should be noted that the rotation axes being collinear means that the two rotation axes coincide or substantially coincide, and it can also be understood that the rotation axes on which the rotation axes are located are coaxial.

[0084] In some embodiments, the second connecting member 12 has a first position that closes the vehicle door 2 ;

[0085] When the second connecting member 12 is in the first position, one side of the first rotating component 131 is rotatably disposed on the first connecting member 11, and the other side is rotatably connected to the second connecting member 12. The first rotating component 131 is transmission-connected to the second switching component 133. One side of the second rotating component 132 is rotatably disposed on the first connecting member 11, and the other side is rotatably connected to the second connecting member 12. The second rotating component 132 is spaced apart from the second switching component 133. The first rotating component 131 and the second rotating component 132 can simultaneously rotate relative to the first connecting member 11 to drive the second connecting member 12 to perform a connecting rod motion relative to the first connecting member 11.

[0086] In some embodiments, the second connecting member 12 has a second position that enables the vehicle door 2 to be opened;

[0087] When the second connecting member 12 is in the second position, one side of the first rotating component 131 abuts against the first switching component 14, and the other side is rotationally connected to the second connecting member 12, the first rotating component 131 is transmission-connected to the second switching component 133, one side of the second rotating component 132 is rotatably disposed on the first connecting member 11, and the other side is rotationally connected to the second connecting member 12, and the second rotating component 132 is spaced from the second switching component 133. The rotation axis where the first rotating component 131 and the second connecting member 12 are rotationally connected is colinear with the rotation axis where the second rotating component 132 and the first connecting member 11 are rotationally connected, so that the second rotating component 132 can drive the second connecting member 12 to rotate around the rotation axis alone, and the first rotating component 131 only plays the role of supporting and providing a rotating shaft at this time.

[0088] In some embodiments, the second connecting member 12 has a transition position, and the transition position refers to the position of the second connecting member 12 when the first motion state and the second motion state transition to each other.

[0089] When the second connecting member 12 is in the transition position, one side of the first rotating component 131 abuts against the first switching component 14, and the other side is rotationally connected to the second connecting member 12, the first rotating component 131 is transmission-connected to the second switching component 133, one side of the second rotating component 132 is rotatably provided on the first connecting member 11, and the other side is rotationally connected to the second connecting member 12, and the second rotating component 132 is in contact with the second switching component 133. Among them, the rotation axis where the first rotating component 131 and the second connecting member 12 are rotationally connected is colinear with the rotation axis where the second rotating component 132 and the first connecting member 11 are rotationally connected, so that the second rotating component 132 can drive the second connecting member 12 to rotate around the rotation axis alone, and the first rotating component 131 only plays the role of supporting and providing a rotating shaft at this time. The second rotating component 132 is in contact with the second switching component 133 mainly so that when the second connecting member 12 moves from the second position to the first position, the second rotating component 132 can transmit the rotational motion to the second switching component 133, so that the second switching component 133 rotates, and then the second switching component 133 transmits the rotational motion to the first rotating component 131, so that the first rotating component 131 resumes rotation, thereby breaking the dead point of the four-bar linkage structure and switching the second connecting member 12 from rotational motion to connecting rod motion.

[0090] In some embodiments, see Figures 1 to 4, the first connecting member 11 is provided with a first boss 111. The first boss 111 is provided with a first axle pin hole 112. The second connecting member 12 is provided with a second boss 121, and the second boss 121 is provided with a second axle pin hole 122. One side of the first rotating component 131 is rotatably arranged in the first axle pin hole 112, and the other side is rotatably arranged in the second axle pin hole 122. By rotatably arranging the two sides of the first rotating component 131 in the first axle pin hole 112 and the second axle pin hole 122 respectively, the first rotating component 131 can use the first boss 111 as a support base and the first axle pin hole 112 as a rotation center to drive the other side of the first rotating component 131 to rotate, and then drive the second connecting member 12 connected to the other side to perform a connecting rod motion, and the trajectory of the connecting rod motion of the second connecting member 12 is carried out along the rotation of the first rotating component 131, but the second connecting member 12 will not perform self-rotation motion at this time.

[0091] Further, the first rotating assembly 131 includes a first rotating rod 1311, a first pin 1312 and a second pin 1313. The first rotating rod 1311 includes a first end and a second end arranged opposite to each other. The first pin 1312 is rotatably inserted into the first shaft pin hole 112, and the first end is sleeved on the first pin 1312 and fixedly connected to the first pin 1312, and the fixed connection method can be threaded fit, interference fit, etc. The second pin 1313 is rotatably inserted into the second shaft pin hole 122, and the second end is sleeved on the second pin 1313 and fixedly connected to the second pin 1313, and the fixed connection method can also be threaded fit, interference fit, etc. By using the first pin 1312 being able to rotate in the first pin hole 112 and the first end being fixedly connected to the first pin 1312, and the second pin 1313 being able to rotate in the second pin hole 122 and the second end being fixedly connected to the second pin 1313, the first end and the second end can be respectively fixed to the first connecting member 11 and the second connecting member 12, and can also perform rotational motion. By rotating the first rotating rod 1311, the rotational motion of the first rotating rod 1311 can be transmitted to the second connecting member 12, and the second connecting member 12 can perform a connecting rod motion along the rotation trajectory.

[0092] In some embodiments, see Figures 1 to 4The first connecting member 11 is provided with a third boss 113, and the third boss 113 is provided with a third shaft pin hole 114. The second connecting member 12 is provided with a fourth boss 123, and the fourth boss 123 is provided with a fourth shaft pin hole 124. One side of the second rotating component 132 is rotatably arranged in the third shaft pin hole 114, and the other side is rotatably arranged in the fourth shaft pin hole 124. By rotatably arranging the two sides of the second rotating component 132 in the third shaft pin hole 114 and the fourth shaft pin hole 124 respectively, the second rotating component 132 can use the first boss 111 as a support base and the third shaft pin hole 114 as a rotation center to drive the other side of the second rotating component 132 to rotate, and then drive the second connecting member 12 connected to the other side to perform a connecting rod motion, and the trajectory of the connecting rod motion of the second connecting member 12 is performed along the rotation of the second rotating component 132, but the second connecting member 12 will not perform self-rotation at this time. It should be noted that during the connecting rod movement of the second connecting member 12, the second rotating component 132 and the first rotating component 131 rotate synchronously, driving the second connecting member 12 to perform connecting rod movement, which not only provides power for the movement of the second connecting member 12, but also improves the stability of the movement of the second connecting member 12.

[0093] Further, the second rotating assembly 132 includes a second rotating rod 1321, a third pin 1322 and a fourth pin 1323. The second rotating rod 1321 includes a third end and a fourth end that are arranged opposite to each other. The third pin 1322 is rotatably inserted into the third shaft pin hole 114. The third end is sleeved on the third pin 1322 and fixedly connected to the third pin 1322. The fourth pin 1323 is rotatably inserted into the fourth shaft pin hole 124. The fourth end is sleeved on the fourth pin 1323 and fixedly connected to the fourth pin 1323. The fixed connection method may be threaded fit, interference fit, etc. The third pin 1322 can rotate in the third shaft pin hole 114 and the third end is fixedly connected to the third pin 1322. The fourth pin 1323 can rotate in the fourth shaft pin hole 124 and the fourth end is fixedly connected to the fourth pin 1323, so that the third end and the fourth end can be fixed to the first connecting member 11 and the second connecting member 12 respectively, and can also perform rotational movement. By rotating the second rotating rod 1321, the rotational motion of the second rotating rod 1321 can be transmitted to the second connecting member 12, and the second connecting member 12 can move along the rotation trajectory. It should be noted that the first rotating rod 1311 drives the second connecting member 12 to move and the second rotating rod 1321 drives the second connecting member 12 to move synchronously, so as to improve the stability of the second connecting member 12 in the first motion state.

[0094] In some embodiments, the third boss 113 is provided with a fifth axis pin hole 115, the fifth axis pin hole 115 is located between the first axis pin hole 112 and the third axis pin hole 114, and the fifth axis pin hole 115 provides a rotatable installation condition for the transfer component for subsequent motion transmission. The transmission mechanism 13 includes a second switching component 133, which is rotatably connected to the third boss 113 through the fifth pin hole, and is used to transmit the motion of the first rotating component 131 and the second rotating component 132. The second switching component 133 is provided to help ensure the synchronization of the motion of the first rotating component 131 and the second rotating component 132.

[0095] Furthermore, the second switching assembly 133 includes a transmission gear 1331 and a transmission pin 1332. The transmission pin 1332 is inserted into the fifth shaft pin hole 115, and the transmission gear 1331 is sleeved on the transmission pin 1332 and is rotatably connected with the transmission pin 1332, so that the transmission gear 1331 can also rotate on its own on the basis of being supported by the transmission pin 1332, so that it has the function of transmitting motion. In order to transmit the motion of the first rotating assembly 131 and the second rotating assembly 132, the transmission gear 1331 is arranged between the first rotating assembly 131 and the second rotating assembly 132, which is conducive to improving the synchronization of the rotation of the two rotating assemblies.

[0096] For further information, see Figure 6 , Figure 8 or Fig.10 , the transmission gear 1331 includes a transmission body 13311 and a plurality of transmission teeth 13312. Along the circumferential direction of the transmission body 13311, the transmission body 13311 is provided with a meshing area and a non-meshing area. A plurality of transmission teeth 13312 are provided in the meshing area along the circumferential direction. By dividing the transmission body 13311 into two parts, one part is provided with meshing teeth, and the other part is not provided with transmission teeth 13312, the transmission gear 1331 can selectively mesh with the first rotating component 131 or the second rotating component 132, and then realize motion transmission. In this embodiment, because the first rotating component 131 only plays a driving role in the first motion state of the second connecting member 12, the second rotating component 132 needs to play a driving role in both the first motion state and the second motion state. Therefore, in this embodiment, the transmission teeth 13312 are selected to mesh with the first rotating component 131 to ensure that the second rotating component 132 can be independently operated in the second motion state, avoiding the transmission of the motion of the second rotating component 132 to the first rotating component 131.

[0097] In some embodiments, the first rotating assembly 131 includes a first rotating gear 1314. The first rotating gear 1314 is fixedly sleeved on the first pin 1312, and the first rotating gear 1314 is arranged near the meshing area and meshes with a plurality of transmission teeth 13312. When the first rotating rod 1311 rotates, the first rotating gear 1314 rotates along with the first rotating rod 1311, and then drives the transmission gear 1331 to rotate, so that the transmission gear 1331 rotates to a target position, which is the position when the first rotating rod 1311 abuts against and hovers with the first connecting member 11, so as to prepare for the subsequent second rotating assembly 132 to drive the transmission gear 1331. When the second rotating assembly 132 drives the transmission gear 1331 to move, the transmission gear 1331 can be meshed with gears to make the first rotating assembly 131 disengage from the abutment with the first connecting member 11.

[0098] Further, the first rotating gear 1314 includes a first rotating body 13141 and a plurality of first rotating teeth 13142. Along the circumferential direction of the first rotating body 13141, the plurality of first rotating teeth 13142 are arranged on at least a portion of the first rotating body 13141. Specifically, the plurality of first rotating teeth 13142 may be arranged all over the circumferential surface of the first rotating body 13141, or may be arranged only on a portion of the circumferential surface of the first rotating body 13141. In the present embodiment, the plurality of first rotating teeth 13142 are arranged only on a portion of the circumferential surface of the first rotating body 13141, and at least a portion of the first rotating teeth 13142 can always mesh with the transmission teeth 13312 on the transmission gear 1331, so as to ensure that the movements of the first rotating component 131 and the second switching component 133 can always be transmitted to each other. In the subsequent description of the door opening and closing process, the specific beneficial effects of enabling at least a portion of the first rotating tooth 13142 to always mesh with the transmission tooth 13312 on the transmission gear 1331 will be described in detail and will not be repeated here.

[0099] Furthermore, the number of the first rotating teeth 13142 is not less than the number of the transmission teeth 13312 , ensuring that the first rotating teeth 13142 and the transmission teeth 13312 are always in a gear meshing state, ensuring the simultaneity of the movement of the first rotating component 131 and the second switching component 133 .

[0100] In some embodiments, see Figure 6 , Figure 8 or Fig.10The transmission gear 1331 further includes an abutting tooth 13313, which is disposed in the non-meshing area and is spaced apart from the transmission tooth 13312. The abutting tooth 13313 and the transmission tooth 13312 are spaced apart and disposed in the non-meshing area, so that the non-meshing area is divided into two sub-non-meshing areas by the abutting tooth 13313. One sub-non-meshing area is located between one side of the abutting tooth 13313 and the transmission tooth 13312, and the other sub-non-meshing area is located between the other side of the abutting tooth 13313 and the transmission tooth 13312. By dividing the non-meshing area into two parts, when the second rotating component 132 cooperates with the second switching component 133, the second rotating component 132 will not cooperate with the transmission teeth 13312 and the contact teeth 13313 of the second switching component 133 during a part of the rotation process, and the second rotating component 132 can cooperate with the contact teeth 13313 on the second switching component 133 during the other part of the rotation process, thereby driving the transmission gear 1331 to rotate, and the transmission gear 1331 then drives the first rotating component to rotate. This process is mainly used when the second connecting member 12 needs to transition from the second motion state to the first motion state.

[0101] In some embodiments, see Figures 6 to 10 , the second rotating assembly 132 includes a second rotating gear 1324. The second rotating gear 1324 is fixedly sleeved on the third pin shaft 1322, and the second rotating gear 1324 is arranged close to the non-meshing area. In the process of the second rotating gear 1324 rotating, the second rotating gear 1324 can abut against the abutting tooth 13313. Specifically, the second rotating gear 1324 is fixedly sleeved on the third pin shaft 1322, and the second rotating gear 1324 is arranged close to the non-meshing area, which is conducive to the second rotating gear 1324 being able to abut against the abutting tooth 13313 within a limited angle of rotation. The position where the second rotating gear 1324 abuts against the abutting tooth 13313 is when the second motion state transitions to the first motion state, or when the first motion state transitions to the second motion state. When the first motion state transitions to the second motion state, the second rotating gear 1324 is only in contact with the abutting tooth 13313, and then the abutting tooth 13313 is stationary, and the second rotating gear 1324 continues to rotate in a direction away from the abutting tooth 13313. When the second motion state transitions to the first motion state, the second rotating gear 1324 is in contact with the abutting tooth 13313, and then the second rotating gear 1324 continues to rotate, pushing the abutting tooth 13313, and then driving the transmission gear 1331 to rotate, and the transmission gear 1331 drives the first rotating assembly 131 to rotate, so that the second connecting member 12 can be converted from a rotational motion to a connecting rod motion.

[0102] In some embodiments, the second rotating gear 1324 includes a second rotating body 13241 and at least one second rotating tooth 13242. The second rotating tooth 13242 is disposed on the circumferential surface of the second rotating body 13241, and when the second rotating tooth 13242 rotates with the second rotating body 13241, the second rotating tooth 13242 can abut against the abutting tooth 13313. In this embodiment, the number of the second rotating tooth 13242 is set to one, and its function is not to mesh with the abutting tooth 13313 in the transmission gear 1331, but mainly to abut against the abutting tooth 13313, so that the rotation of the second rotating body 13241 can be transmitted to the first rotating gear 1314 through the transmission gear 1331, so that the first rotating assembly 131 is no longer abutted against the first connecting member 11, so that the first rotating assembly 131 and the second rotating assembly 132 resume synchronous rotation, and realize the connecting rod movement of the second connecting member 12.

[0103] In some embodiments, see Figure 5 and Figure 6 The second connecting member 12 has a first position, which is the position of the second connecting member 12 when the vehicle door 2 is in a closed state. When the second connecting member 12 is in the first position, the transmission tooth 13312 is meshed with the first rotating tooth 13142, and the abutting tooth 13313 is spaced apart from the second rotating tooth 13242, ensuring that the first rotating gear 1314 and the transmission gear 1331 remain in meshing state to prepare for subsequent motion transmission, and the abutting tooth 13313 is spaced apart from the second rotating tooth 13242 to ensure that the second rotating gear 1324 in the second rotating assembly 132 is in an independent rotating state.

[0104] In some embodiments, see Fig. 9 and Fig.10The second connecting member 12 has a second position, which is the position of the second connecting member 12 when the vehicle door 2 is in the open state. The open state here refers to the state in which the vehicle door 2 is fully opened, not just partially opened. When the second connecting member 12 is in the second position, the transmission tooth 13312 is meshed with the first rotating tooth 13142, and the abutting tooth 13313 is spaced apart from the second rotating tooth 13242, ensuring that the first rotating gear 1314 and the transmission gear 1331 are always in meshing state to prepare for motion transmission, and the abutting tooth 13313 is spaced apart from the second rotating tooth 13242 to ensure that the second rotating gear 1324 in the second rotating assembly 132 is in an independent rotating state. It should be noted that when the second connecting member 12 is in the second position and the second connecting member 12 is in the first position, although the transmission tooth 13312 and the first rotating tooth 13142 are in a meshing relationship, and the abutting tooth 13313 and the second rotating tooth 13242 are in a spaced relationship, the first rotating tooth 13142, the second rotating tooth 13242 and the transmission tooth 13312 at the two positions have changed their positions due to rotation, but the positional relationship between them is still that the transmission tooth 13312 and the first rotating tooth 13142 are in a meshing relationship, and the abutting tooth 13313 and the second rotating tooth 13242 are in a spaced relationship. Such a relationship can be achieved mainly because the abutting tooth 13313 divides the non-meshing area into two areas, so that when in the first position and the second position, the second rotating tooth 13242 is always in the non-meshing area, ensuring the independent rotation of the second rotating gear 1324.

[0105] In some embodiments, see Figure 7 and Figure 8, the second connecting member 12 has a transition position. The transition position refers to the position of the second connecting member 12 when the first motion state and the second motion state transition to each other. When the second connecting member 12 is in the transition position, the transmission tooth 13312 is meshed with the first rotating tooth 13142, and the abutment tooth 13313 is abutted with the second rotating tooth 13242. When the second connecting member 12 enters the first position from the transition position, the second rotating gear 1324 rotates, and the second rotating tooth 13242 pushes the abutment tooth 13313, thereby driving the transmission gear 1331 to rotate. The transmission gear 1331 rotates, and the first rotating tooth 13142 is driven to rotate through the transmission tooth 13312, and the rotation direction of the first rotating gear 1314 is the same as the rotation direction of the second rotating gear 1324, so that the first rotating assembly 131 and the second rotating assembly 132 are synchronously rotated, so that the second connecting member 12 can smoothly perform the connecting rod movement. When the second connecting member 12 enters the second position from the transition position, the second rotating gear 1324 rotates in the direction away from the abutting tooth 13313. At this time, the first rotating component 131 and the second switching component 133 are in a suspended state, and the second rotating component 132 rotates independently, driving the second connecting member 12 to transform from connecting rod motion to rotational motion.

[0106] It should be noted that in any of the aforementioned embodiments, a condition needs to be met in order to achieve the transition between the connecting rod motion and the rotational motion. Specifically, when the second connecting member 12 is in the transition position, the second axle pin hole 122 is coaxial with the third axle pin hole 114. When the second axle pin hole 122 and the third axle pin hole 114 are coaxial, it means that the second end of the first rotating component 131 is equivalent to acting as a support body for the second connecting member 12 to rotate around the second axle pin hole 122, and the second rotating rod 1321 in the second rotating component 132 continues to rotate. On the basis that the first rotating component 131 hinders the movement of the second connecting member 12, the second connecting member 12 will use the axis of the second axle pin hole 122 as the rotation axis to rotate and complete the second motion state of the second connecting member 12.

[0107] For further information, see Figure 1 and Figure 2, a limiting protrusion 13111 is provided at the first end, and a limiting protrusion 141 is provided at the first connecting member 11. When the second connecting member 12 is in the transition position, the limiting protrusion 13111 abuts against the limiting protrusion 141. By setting the limiting protrusion 13111 and the limiting protrusion 141 to abut against each other, when the first rotating component 131 rotates to the position corresponding to the transition position of the second connecting member 12, the limiting protrusion 13111 will abut against the limiting protrusion 141, so that the first rotating rod 1311 stops rotating and is in a suspended state, and the second motion state of the movable station is completed by the second rotating component 132. By abutting the limiting protrusion 141 and the limiting protrusion 13111, the first rotating rod 1311 stops moving. At this time, the second connecting member 12 uses the axis of the second axle pin hole 122 as the rotation axis. When the second rotating rod 1321 continues to rotate, the second connecting member 12 can rotate on the rotation axis to realize the transformation from connecting rod movement to rotational movement.

[0108] See also Figures 5 to 10 The specific working process of the hinge 1 provided in this application is as follows:

[0109] The process of the door 2 being converted from the closed state to the open state: the first rotating rod 1311 rotates along the first direction with the central axis of the first axle pin hole 112 as the rotating axis, and the second rotating rod 1321 rotates along the second direction with the central axis of the third axle pin hole 114 as the rotating axis. The first rotating rod 1311 and the second rotating rod 1321 rotate synchronously at this time, thereby driving the second connecting member 12 to perform a connecting rod motion along the motion trajectory of the second end of the first rotating rod 1311 and the fourth end of the second rotating rod 1321. At this time, the connecting rod motion is a linear motion or an approximately linear motion. When the first rotating rod 1311 and the second rotating rod 1321 rotate, the first rotating gear 1314 rotates with the rotation of the first rotating rod 1311, and meshes with the transmission gear 1331 to rotate, and the second rotating gear 1324 rotates with the rotation of the second rotating rod 1321. When the connecting rod of the second connecting member 12 moves to the first position, the limiting protrusion 13111 on the first rotating rod 1311 abuts against the limiting protrusion 141 on the first connecting member 11, the first rotating rod 1311 is suspended, the first rotating gear 1314 and the transmission gear 1331 are stationary, and the abutting tooth 13313 of the transmission gear 1331 is in contact with the second rotating tooth 13242 of the second rotating gear 1324. In addition, at this time, the second shaft pin hole 122 to which the second end of the first rotating rod 1311 is rotatably connected is coaxial with the third shaft pin hole 114, and the first rotating rod 1311 is converted from the role of driving the second connecting member 12 to move to the role of supporting the second connecting member 12 to rotate with the second pin shaft 1313 as the rotation axis. Then, the second rotating rod 1321 in the second rotating assembly 132 continues to rotate in the first direction. On the basis of the restriction of the first rotating rod 1311, the second connecting member 12 no longer performs a connecting rod movement along the trajectory of the fourth end of the second rotating rod 1321, but converts the force of the second rotating rod 1321 acting on the movement of the second connecting member 12 into a force driving the second connecting member 12 to rotate, so that the second connecting member 12 rotates around the second pin 1313. The process of the second connecting member 12 performing a connecting rod movement is used to drive the vehicle door 2 to perform a connecting rod movement to achieve the purpose of avoiding other vehicle doors 2, and the process of the second connecting member 12 performing a rotational movement is used to drive the vehicle door 2 to perform a rotational movement to achieve the purpose of opening the door.

[0110] The process of the vehicle door 2 being converted from the open state to the closed state: the second rotating rod 1321 rotates along the second direction with the third pin shaft 1322 as the rotating shaft, and the second direction is opposite to the first direction. If the first direction is clockwise, then the second direction is counterclockwise. Driven by the fourth end of the second rotating rod 1321, the second connecting member 12 rotates with the second pin shaft 1313 as the rotating shaft, and its rotation direction is the second direction. During the rotation process, the vehicle door 2 connected to the second connecting member 12 will gradually close. When the second connecting member 12 rotates to the transition position, the second rotating tooth 13242 of the second rotating gear 1324 will abut against the abutting tooth 13313 of the transmission gear 1331, and at this time, the second axis pin hole 122 where the second end of the first rotating rod 1311 is located is coaxial with the third axis pin hole 114. Then, the second rotating rod 1321 continues to rotate in the second direction, and the second rotating tooth 13242 pushes the abutting tooth 13313 in the second direction, so that the transmission gear 1331 rotates in the first direction, and the transmission gear 1331 then drives the first rotating gear 1314 to rotate in the second direction, and the limiting protrusion 13111 of the first rotating rod 1311 and the limiting protrusion 141 of the first connecting member 11 gradually move away from each other, and the second end of the first rotating rod 1311 and the fourth end of the second rotating rod 1321 jointly drive the second connecting member 12 to make a connecting rod movement, and the second connecting member 12 drives the vehicle door 2 to return to the position when it is in the closed state.

[0111] In summary, it can be known from the above embodiments that the transmission mechanism 13 drives the second connecting member 12 to perform connecting rod movement and rotational movement, so that the vehicle door 2 connected to the second connecting member 12 can perform connecting rod movement and rotational movement. The vehicle door 2 performs connecting rod movement driven by the transmission mechanism 13, so that the vehicle door 2 can move away from or approach another vehicle door 2 that is not connected to the second connecting member 12 in a linear direction, thereby achieving the avoidance or closing of the two vehicle doors 2. The vehicle door 2 performs rotational movement driven by the transmission mechanism 13, thereby achieving the opening or closing of the vehicle door 2. Regardless of opening or closing the vehicle door 2, the hinge 1 can independently drive the vehicle door 2 to perform connecting rod movement and rotational movement without being affected by the other vehicle door 2. There is no order for opening and closing the vehicle door 2, thereby improving the operational flexibility of the hinge 1 in cooperating with the vehicle door 2 to open and close, and then improving the applicability of the vehicle door assembly in different environments.
