[0002] A hinge is a mechanical structure used to connect two parts and allow them to rotate relative to each other. The hinge movement mode in the related art is relatively simple, which can only allow one of the two parts to rotate relative to the other part, and the rotating part may interfere with other parts during the rotation process.

[0003] For example, in the case where the hinge is applied to a split vehicle tailgate, in order to ensure that the split vehicle tailgate has good sealing performance, the two door bodies of the split vehicle tailgate are often designed to overlap each other, which means that when the user wants to open one of the door bodies on the inner side of the overlap, the other door body on the outer side of the overlap must be opened first, otherwise the door body on the outer side of the overlap will interfere with the rotation of the door body on the inner side of the overlap.

DETAILED DESCRIPTION

[0043] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0044] In the present disclosure, it is necessary to understand that the directional words used, such as "upper" and "lower", etc., are defined by the drawing directions of the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation of the present disclosure. For example, the up and down directions may be the up and down directions of a vehicle. The terms "inside and outside" refer to the inside and outside of the corresponding structural contours. In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description of the reference drawings, the same mark in different drawings represents the same element.

[0045] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0046] like Figures 1 to 10 As shown, according to the first aspect of the present disclosure, a hinge is provided, comprising a hinge body 1 and a guide member 4, wherein the guide member 4 is guided and cooperated with the hinge body 1 and can guide the movement of the hinge body 1 relative to the guide member 4, so that the hinge body 1 can have a first motion state and a second motion state, wherein in the first motion state, at least part of the hinge body 1 can move, and in the second motion state, at least part of the hinge body 1 can rotate.

[0047] It is understandable that the hinge body 1 is connected between the movable part and the fixed part to allow the movable part to move relative to the fixed part. In the first movement state, at least part of the hinge body 1 can move, thereby driving the movable part to move relative to the fixed part, and in the second movement state, at least part of the hinge body can rotate, thereby driving the movable part to rotate relative to the fixed part.

[0048] Here, it should be noted that the above-mentioned at least part of the hinge body 1 can move means that the hinge body 1 has translational movement, which does not mean that the hinge body 1 only has translational movement. The hinge body 1 can also have other movements (such as rotation) while having translational movement.

[0049] Through the above technical solution, the movement of the hinge body 1 is guided by the guide member 4, so that the hinge body 1 can have a first movement state (that is, at least part of the hinge body 1 can move) and a second movement state (that is, at least part of the hinge body 1 can rotate) under the action of an external force. Therefore, before the movable part rotates relative to the fixed part through the hinge body 1, it can first move through the hinge body 1, so that the movable part does not interfere or collide with other adjacent parts during the subsequent rotation process.

[0050] The hinge provided by the present disclosure has various motion modes and can be used in various application scenarios. For example, when the hinge is applied to a vehicle, the hinge can be used to connect the vehicle body and one of the split vehicle tailgates (such as the first door body 201 mentioned below). In this way, when the user needs to open the first door body 201, the hinge body 1 can first have a first motion state, that is, at least a portion of the hinge body 1 is moved in a direction away from the other tailgate (such as the second door body 202 mentioned below) in the split vehicle tailgate under the guiding action of the guide member 4, so that the first door body 201 and the second door body 202 are staggered from each other. After the first door body 201 and the second door body 202 are staggered from each other, the hinge body 1 can have a second motion state, that is, at least a portion of the hinge body 1 is rotated in a direction away from the vehicle body under the guiding action of the guide member 4, so that the first door body 201 can be opened. In this way, the first door body 201 can be opened independently without opening the second door body 202 in advance before opening the first door body 201. The opening process of the first door body 201 is relatively simple, which is conducive to improving the opening efficiency and opening speed of the first door body 201.

[0051] The process of switching the first door body 201 from the open position to the closed position is opposite to the process of switching the first door body 201 from the closed position to the open position. That is, when the user needs to close the first door body 201, the hinge body 1 can be placed in the second motion state first, that is, at least part of the hinge body 1 is rotated toward the direction close to the vehicle body under the guiding action of the guide member 4. When the first door body 201 is rotated to the preset position, the hinge body 1 can have the first motion state, that is, at least part of the hinge body 1 can be moved toward the direction close to the first door body 201 in the door assembly under the guiding action of the guide member 4, thereby achieving the closing of the first door body 201. In this way, the first door body 201 can be closed independently without opening the second door body 202 in advance before closing the first door body 201. The closing process of the first door body 201 is relatively simple, which is conducive to improving the closing efficiency and closing speed of the first door body 201.

[0052] That is to say, when the above-mentioned hinge is applied to the split tailgate of a vehicle, the hinge can independently open or close the first door body 201 of the door assembly, and when opening or closing the first door body 201, there is no need to open the second door body 202 in advance. That is to say, no matter what state the second door body 202 is in, whether it is open or closed, it will not affect the user's opening or closing of the first door body 201 alone. Thereby, the opening and closing process of the door assembly is simplified and the user experience is improved.

[0053] It should be noted that the above-mentioned hinge body 1 can be driven by the driving mechanism 2 to have the above-mentioned first motion state and second motion state, or the user can manually apply external force to the movable part or the hinge body 1 so that the hinge body 1 can have the first motion state and the second motion state under the guidance of the guide member 4.

[0054] In order to ensure that the hinge body 1 can move along the preset motion trajectory, optionally, as Figure 1 As shown, a guide portion 41 is provided on the guide member 4, and the hinge body 1 has a matching portion 13 that slidably matches with the guide portion 41, and the guide portion 41 includes a first guide segment 42 and a second guide segment 43 that are connected. When the matching portion 13 slides along the first guide segment 42, the hinge body 1 is in a first motion state, and when the matching portion 13 slides along the second guide segment 43, the hinge body 1 is in a second motion state.

[0055] The hinge body 1 and the guide member 4 are formed into a sliding fit, so that during the movement of the hinge body 1, the guide portion 41 on the guide member 4 can limit the matching portion 13 on the hinge body 1. Under the action of external force, the hinge body 1 can only move along the first guide section 42 and the second guide section 43, thereby having a first motion state and a second motion state.

[0056] The present disclosure does not limit the specific shape of the guide portion 41. As an implementation method provided by the present disclosure, Figure 1 , Figures 8 to 10 As shown, the guide portion 41 is formed into an arc structure, the first guide segment 42 is formed into a first arc segment, and the second guide segment 43 is formed into a second arc segment. The arc-shaped first guide segment 42 and the second guide segment 43 are slidably matched with the matching portion 13 of the hinge body 1, so that the hinge body 1 can have a first motion state and a second motion state. The first guide segment 42 is formed into a first arc segment, which can make at least part of the hinge body 1 move obliquely in the first motion state, and the second guide segment 43 is formed into a second arc segment, which is conducive to rotating at least part of the hinge body 1, so as to have a second motion state.

[0057] As another embodiment of the present disclosure, the first guide segment 42 can also be formed as a first straight segment, and the second guide segment 43 can also be formed as a second arc segment. In this way, the straight first guide segment 42 and the arc second guide segment 43 can slide with the matching portion 13 of the hinge body 1, so that the hinge body 1 can have the first motion state and the second motion state.

[0058] For the implementation scheme in which the first guide segment 42 is formed as a first arc segment and the second guide segment 43 is formed as a second arc segment, the curvature of the first arc segment may be the same as or different from the curvature of the second arc segment. The present disclosure does not limit this, and the appropriate curvatures of the first arc segment and the second arc segment may be selected according to the actual application scenario of the hinge.

[0059] As an embodiment of the present disclosure, Figure 1 , Figures 8 to 10 As shown, the curvature of the first arc segment is different from the curvature of the second arc segment. Thus, by reasonably designing the curvatures of the first arc segment and the second arc segment, the mating portion 13 of the hinge body 1 can move smoothly between the first arc segment and the second arc segment, thereby effectively avoiding the occurrence of jamming when the hinge body 1 switches from the first motion state to the second motion state.

[0060] The present disclosure does not limit the specific structure of the guide portion 41 of the guide member 4 and the matching portion 13 of the hinge body 1, as long as the guide portion 41 and the matching portion 13 cooperate with each other to enable the hinge body 1 to have a first motion state and a second motion state. Figure 1 As shown, the guide portion 41 includes a guide groove, and the matching portion 13 includes a guide rod, one end of which is slidably disposed in the guide groove. In this way, during the movement of the guide rod in the guide groove, the guide rod can drive the hinge body 1 to move, so that the hinge body 1 can have the above-mentioned first motion state and second motion state.

[0061] In other embodiments, the guide portion 41 may be a guide protrusion, and the matching portion 13 may be a groove matching with the guide protrusion.

[0062] The hinge body 1 may have any appropriate structure, as long as the hinge body 1 can simultaneously connect two components that need to move relative to each other and can cooperate with the guide member 4 for guidance.

[0063] As an embodiment of the present disclosure, Figure 1 , Figures 8 to 10 As shown, the hinge body 1 may include a connecting seat 11 and a connecting rod 12. The guide member 4 cooperates with the connecting seat 11 in a guiding manner. The connecting rod 12 is hinged to the connecting seat 11. In a first motion state, the connecting seat 11 can move. In a second motion state, the connecting seat 11 can rotate.

[0064] It can be understood that the connection seat 11 is used to connect with the movable part (such as the first door body 201 mentioned below), so as to drive the movable part to move or rotate, and the two ends of the connecting rod 12 are respectively hinged with the fixed part and the connection seat 11. For example, when the above hinge is applied to a vehicle, the connection seat 11 can be used to connect with the first door body 201, the first end of the connecting rod 12 is hinged with the connection seat 11, and the second end of the connecting rod 12 is used to hinge with the vehicle body, and the hinge body 1 can have a first motion state so that the connection seat 11 can drive the first door body 201 to move toward or away from the second door body 202, and the hinge body 1 can also have a second motion state so that the connection seat 11 can drive the first door body 201 to rotate toward or away from the vehicle body.

[0065] When the connecting seat 11 is in the first movement state, the connecting seat 11 can drive the first door body 201 to move in the direction away from the second door body 202, and the connecting rod 12 hinged to the vehicle body and the connecting seat 11 can cooperate with the change of the position of the connecting seat 11; when the connecting seat 11 is in the second movement state, the connecting seat 11 can drive the first door body 201 to rotate in the direction away from the vehicle body, and the connecting rod 12 hinged to the vehicle body and the connecting seat 11 can cooperate with the change of the position of the connecting seat 11. During the movement of the hinge body 1, the connecting rod 12 can adapt to the posture of the connecting seat 11 on the one hand, and maintain the connection between the first door body 201 and the vehicle body on the other hand.

[0066] Alternatively, if Figure 1 as well as Figures 8 to 10 As shown, the connection between the matching portion 13 and the hinge body 1 is located on the side of the connecting rod 12 away from the vehicle body, and the guide portion 41 is formed into an arc-shaped structure protruding in a direction away from the vehicle body.

[0067] Optionally, from the first end of the first arc segment to the second end of the second arc segment, the distance between the first arc segment and the second end of the connecting rod 12 gradually increases, and from the first end of the second arc segment to the second end of the second arc segment, the distance between the second arc segment and the second end of the connecting rod 12 gradually decreases, and the second end of the first arc segment is connected to the first end of the second arc segment. Figure 8 and Fig. 9 As shown, when the matching portion 13 slides along the first guide segment 42 (ie, the first arc segment), the matching portion 13 applies an oblique pulling force to the connecting seat 11 in a direction close to or away from the vehicle body (for example, Figure 8 In the embodiment of the present invention, a force is applied to the connecting seat 11 obliquely upward to the right or obliquely downward to the left), at this time, the connecting seat 11 can translate toward or away from the second door body 202, thereby making the first door body 201 approach or move away from the second door body 202 to avoid being stopped by the second door body 202.

[0068] like Fig. 9 and Fig.10 As shown, when the matching portion 13 slides along the second guide section 43 (i.e., the second arc section), the matching portion 13 applies an oblique pulling force to the connecting seat 11 in a direction closer to or away from the vehicle body (for example, a force applied to the connecting seat 11 obliquely downward to the right or obliquely upward to the left in FIG9 ). At this time, the connecting seat 11 can only rotate, thereby driving the first door body 201 to rotate in a direction away from or close to the vehicle body, thereby enabling the first door body 201 to be opened or closed.

[0069] Alternatively, if Figure 1 As shown, the connecting seat 11 may include a seat body 111, a first hinge seat 113 and a matching portion 13, wherein the matching portion 13 and the first hinge seat 113 are located on the same side of the seat body 111, the connecting rod 12 is hinged to the first hinge seat 113, and the guide member 4 is guided and matched with the matching portion 13. The seat body 111 and the connecting rod 12 can be respectively connected to two objects that need to move relative to each other (such as the vehicle body and the first door body 201).

[0070] As an embodiment of the present disclosure, the connection seat 11 further includes a connection protrusion 112, the seat body 111 is connected to the first end of the connection protrusion 112, and the matching portion 13 is arranged on the second end of the connection protrusion 112. In other words, the matching portion 13 may also have a certain distance from the seat body 111, so that by reasonably designing the distance between the matching portion 13 and the seat body 111 and the length of the connecting rod 12, the matching portion 13, the guide portion 41 and the connecting rod 12 cooperate with each other, so that the hinge body 1 can have a first motion state and a second motion state.

[0071] In the present disclosure, the second end of the connecting rod 12 can be connected to the fixed component (such as the vehicle body) in any appropriate manner. For example, the end of the connecting rod 12 away from the seat body 111 can be directly hinged to the fixed component or indirectly hinged to the fixed component, and the present disclosure does not limit this. As an embodiment of the present disclosure, Figure 1 As shown, the hinge further comprises a mounting member 3, and the hinge body 1 and the guide member 4 are both mounted on the mounting member 3. The mounting member 3 can be used to be mounted on a fixed component (such as a vehicle body). Since the hinge body 1 and the guide member 4 are both mounted on the mounting member 3, the hinge body 1 and the guide member 4 can be integrated into an integral structure, which is convenient for the installation of the hinge.

[0072] Alternatively, if Figure 1 As shown, the second hinge seat 31 is provided on the mounting member 3. In this way, the end of the connecting rod 12 away from the seat body 111 can be connected to the mounting member 3 through the second hinge seat 31, and the connection between the connecting rod 12 and the mounting member 3 is also more convenient.

[0073] According to a second aspect of the present disclosure, a hinge assembly 100 is provided, comprising the hinge as described above. The hinge assembly 100 has all the beneficial effects of the hinge as described above, which will not be described in detail herein.

[0074] In order to facilitate driving the hinge body 1 to move, optionally, as Figures 1 to 4 , Figures 8 to 10 As shown, the hinge assembly 100 may further include a driving mechanism 2, which is connected to the hinge body 1 and can move the hinge body 1. Thus, by controlling the driving mechanism 2, the hinge body 1 can be driven to have different motion states.

[0075] For example, when the above-mentioned hinge assembly 100 is applied to a door assembly of a vehicle, when the user needs to open the first door body 201, the driving mechanism 2 can be controlled to make the hinge body 1 have a first motion state first, and drive the hinge body 1 to move in a direction away from the second door body 202, so that the first door body 201 and the second door body 202 are staggered with each other. After the first door body 201 and the second door body 202 are staggered with each other, the driving mechanism 2 is used to make the hinge body 1 have a second motion state, and drive the hinge body 1 to rotate in a direction away from the vehicle body, so that the first door body 201 can be opened.

[0076] When the user needs to close the first door body 201, the driving mechanism 2 can be controlled to put the hinge body 1 in the second movement state first, so that the hinge body 1 rotates toward the direction close to the vehicle body under the guidance of the guide member 4, and then the driving mechanism 2 can be controlled to put the hinge body 1 in the first movement state, so that the hinge body 1 can move toward the direction close to the second door body 202 in the door assembly under the guidance of the guide member 4, and the first door body 201 can also be closed independently.

[0077] In order to facilitate driving the hinge body 1 to move, optionally, as Figures 1 to 3 , Figure 5 , Figure 8 as well as Fig.10 As shown, the guide member 4 is provided with a guide portion 41, the hinge body 1 has a matching portion 13 which is slidably matched with the guide portion 41, the guide portion 41 includes a first guide section 42 and a second guide section 43 which are connected, the driving mechanism 2 includes an actuating portion 21, the actuating portion 21 is connected to the matching portion 13, the actuating portion 21 can drive the matching portion 13 to slide along the first guide section 42 so that the hinge body 1 is in a first motion state, the actuating portion 21 can also drive the matching portion 13 to slide along the second guide section 43 so that the hinge body 1 is in a second motion state.

[0078] In other words, the hinge body 1 can have different motion states through the same actuating part 21. This is helpful to reduce the cost increase caused by using multiple different driving mechanisms 2 or multiple actuating parts 21. On the other hand, it can also simplify the structure of the entire hinge assembly 100, improve the compactness of the hinge assembly 100, and facilitate its layout.

[0079] In order to make the actuator 21 move along a preset trajectory, optionally, as Figures 1 to 3 , Figure 5 As shown, the guide portion 41 is formed into an arc structure, the first guide segment 42 is formed into a first arc segment, and the second guide segment 43 is formed into a second arc segment. The driving mechanism 2 also includes a rotating member 22 and a rotation structure 9. The actuating portion 21 is arranged on the rotating member 22. The rotation structure 9 is connected to the rotating member 22 and is used to drive the rotating member 22 to rotate. The actuating portion 21 can have a first motion trajectory 14 and a second motion trajectory 15 driven by the rotating member 22. The first motion trajectory 14 is parallel to the first arc segment, and the second motion trajectory 15 is parallel to the second arc segment. By driving the rotating member 22 to rotate through the rotation structure 9, the fixed actuating portion 21 on the rotating member 22 can move along the first motion trajectory 14 and the second motion trajectory 15, thereby driving the hinge body 1 to move, and the hinge body 1 has a first motion state and a second motion state.

[0080] In order to realize that the rotation structure 9 drives the rotating member 22 to rotate, as an embodiment of the present disclosure, as shown in FIG. Figures 1 to 3 , Figure 5 As shown, the rotating member 22 is a rotating belt 221, and the driving mechanism 2 further includes a transmission assembly 24, which includes a driving wheel 241 and a driven wheel 242. The driving wheel 241 is sleeved on the output shaft 23 of the rotating structure 9, and the driving wheel 241 is connected to the rotating belt 221 through the driven wheel 242.

[0081] The driving wheel 241 and the driven wheel 242 cooperate in transmission, and can transmit the power of the actuating structure 9 to the rotating belt 221, and drive the actuating part 21 to move along the motion track through the rotating belt 221, thereby driving the connecting seat 11 to move and rotate. Due to the flexible characteristics of the rotating belt 221, it is easy to set the shape of the rotating belt 221, so that the shape of the rotating belt 221 matches the desired motion track, and the actuating part 21 moves along the preset motion track.

[0082] It should be noted that the present disclosure does not limit the specific number of driven wheels 242 in the transmission assembly 24. There can be one driven wheel 242 or more driven wheels 242, as long as the driven wheel 242 can cooperate with the driving wheel 241 to drive the actuator 21 to rotate.

[0083] As an embodiment of the present disclosure, the number of the above-mentioned driven wheels 242 is multiple, and the multiple driven wheels 242 are arranged around the driving wheel 241. The multiple driven wheels 242 jointly support the rotating belt 221 and make the rotating belt 221 have a first section 222 and a second section 223. The first section 222 is parallel to the first arc section, and the second section 223 is parallel to the second arc section. The multiple driven wheels 242 arranged around the driving wheel 241 can not only transmit the power of the actuating structure 9 to drive the rotating belt 221 to rotate, but also can jointly support the rotating belt 221. By setting the positions of the multiple driven wheels 242, the multiple driven wheels 242 support the rotating belt 221 from different positions, so that the rotating belt 221 can maintain a preset shape, that is, the rotating belt 221 can have a first section 222 and a second section 223. When the actuating part 21 moves along the first section 222, it has a first motion track 14, and when the actuating part 21 moves along the second section 223, it has a second motion track 15.

[0084] As another embodiment, in order to enable the rotating belt 221 to maintain a preset shape, so that the actuating portion 21 can move along a preset motion trajectory, optionally, as Figure 1 and Figure 2 As shown, there is at least one driven wheel 242, and the driving mechanism 2 further includes at least one supporting wheel 25. The at least one driven wheel 242 and the at least one supporting wheel 25 jointly support the rotating belt 221 and make the rotating belt 221 have a first section 222 and a second section 223. The first section 222 is parallel to the first motion track 14, and the second section 223 is parallel to the second motion track 15. Here, the driven wheel 242 plays a role in transmitting power, and the driven wheel 242 and the supporting wheel 25 jointly support the rotating belt 221, so that the rotating belt 221 can always have the first section 222 and the second section 223 during the rotation process, and then can drive the actuating part 21 to move according to the preset motion track.

[0085] In particular, for the above-mentioned implementation in which the first motion trajectory 14 is parallel to the first arc segment, the second motion trajectory 15 is parallel to the second arc segment, and the curvatures of the first arc segment and the second arc segment are different, the rotating belt 221 is supported by multiple driven wheels 242, or the driven wheel 242 and the support wheel 25 jointly support the rotating belt 221, so that the rotating belt 221 can have an arc-shaped first segment 222 and an arc-shaped second segment 223 with different curvatures.

[0086] In order to avoid reducing the friction force on the rotating belt 221 during the rotation process, the outer surface of the supporting wheel 25 is optionally a smooth surface. The friction between the supporting wheel 25 with a smooth outer surface and the rotating belt 221 is small during the rotation process, and the rotation of the rotating belt 221 is not easily affected.

[0087] In order to facilitate fixing the above driven wheel 242, optionally, as Figures 1 to 3 as well as Figure 6 As shown, the hinge assembly 100 further includes a guide member 4 and a first fastener 5. The guide member 4 is fixed to the vehicle body, and the first fastener 5 can pass through the driven wheel 242 and be inserted into the guide member 4. The first fastener 5 can reliably fix the driven wheel 242 on the guide member 4, and the transmission connection between the driven wheel 242 and the driving wheel 241 is reliable, which effectively avoids the situation that the driven wheel 242 shakes or even falls off during use, which affects the normal use of the hinge assembly 100.

[0088] In order to reduce the friction between the driven wheel 242 and the first fastener 5 when the driven wheel 242 rotates, optionally, as Figure 6 As shown, the hinge assembly 100 may further include a first bearing 6, the inner ring of the first bearing 6 is sleeved on the outer surface of the first fastener 5, and the driven wheel 242 is sleeved on the outer ring of the first bearing 6. The friction between the driven wheel 242 and the first fastener 5 connected by the first bearing 6 is small, and it is not easy to wear, and the service life of the driven wheel 242 and / or the first fastener 5 is long.

[0089] In order to facilitate fixing the above-mentioned support wheel 25, optionally, as Figures 1 to 3 as well as Figure 7 As shown, the hinge assembly 100 may further include a guide member 4 and a second fastener 7, wherein the guide member 4 is fixed to the vehicle body, and the second fastener 7 can pass through the driven wheel 242 and be inserted into the guide member 4. The second fastener 7 can reliably fix the support wheel 25 on the guide member 4, and the support wheel 25 is reliably fixed on the guide member 4, which effectively avoids the support wheel 25 shaking or even falling off during use, thereby affecting the normal use of the hinge assembly 100.

[0090] As an embodiment of the present disclosure, the support wheel 25 can be fixed on the outer surface of the second fastener 7 through a second bearing. The friction between the support wheel 25 and the second fastener 7 is small, not easy to wear, and has a long service life.

[0091] As another embodiment provided by the present disclosure, Figure 7 As shown, the support wheel 25 can be constructed as a third bearing 251, the inner ring of the third bearing 251 is sleeved on the outer surface of the second fastener 7, and the outer ring of the third bearing 251 contacts the inner surface of the rotating belt 221. In this way, the friction between the support wheel 25 and the second fastener 7 can also be reduced.

[0092] Here, it should be noted that the present disclosure does not limit the specific types of the rotating belt 221, the driving wheel 241 and the driven wheel 242. As an embodiment of the present disclosure, Figures 1 to 3 as well as Figures 5 and 6As shown, the rotating belt 221 is a toothed belt, the driving wheel 241 is a driving gear, and the driven wheel 242 is a driven gear. The transmission connection between the mutually meshing driving gear and the driven gear, and the driven gear and the toothed belt is more reliable and not easy to slip, and the hinge assembly 100 has higher reliability and stability.

[0093] In other embodiments, the rotating belt 221 may also be a friction belt, the driving wheel 241 may be a driving friction wheel, and the driven wheel 242 may be a driven friction wheel.

[0094] In order to facilitate driving the driving wheel 241 to rotate, optionally, as Figure 4 As shown, the above-mentioned rotation structure 9 may include a motor 91, which is transmission-connected to the rotating member 22, and the motor 91 serves as a power source to drive the rotating member 22 to rotate.

[0095] Optionally, the actuating structure 9 may further include a reducer 92, the motor 91 is in transmission connection with the reducer 92, and the reducer 92 is in transmission connection with the rotating member 22. The reducer 92 can reduce the speed and increase the distance of the motor 91, so that the motor 91 with a relatively small torque can drive the actuating part 21, which is conducive to reducing the volume of the motor 91, thereby improving the compactness of the entire hinge assembly 100.

[0096] In order to facilitate the installation of the motor 91 and the reducer 92, optionally, as Figure 1 and Figure 4 As shown, the hinge assembly 100 further includes a housing 8, and the reducer 92 and the motor 91 are both installed in the housing 8. The housing 8 can be installed on a fixed component (such as a vehicle body). On the one hand, the housing 8 can integrate the reducer 92 and the motor 91 into a whole, which is convenient for fixing the reducer 92 and the motor 91. On the other hand, it can also protect the reducer 92 and the motor 91, effectively preventing dust and other impurities from entering the reducer 92 and / or the motor 91, which is easy to damage the reducer 92 and / or the motor 91, and the reducer 92 and the motor 91 have a longer service life.

[0097] In order to dissipate heat for the motor 91, optionally, as Figure 4 As shown, the housing 8 is also provided with a plurality of heat dissipation holes 81. Thus, during the use of the motor 91, the motor 91 can dissipate heat through the plurality of heat dissipation holes 81, and the motor 91 can always operate within a reasonable temperature range, which is beneficial to improving the life of the motor 91.

[0098] Alternatively, if Figure 2 and Figure 5As shown, the guide portion 41 includes a guide groove, the matching portion 13 includes a guide rod, one end of the guide rod is slidably disposed in the guide groove, a through hole 211 is formed on the actuating portion 21, and one end of the guide rod away from the guide groove is penetrated through the through hole 211. Since the guide rod can pass through the through hole 211 provided on the actuating portion 21 and slidably cooperate with the guide groove, in the process of the movement of the guide rod, the guide rod can drive the actuating portion 21 to move, thereby driving the hinge body 1 to move, so that the hinge body 1 has a first motion state and a second motion state.

[0099] According to a third aspect of the present disclosure, a vehicle door assembly 200 is provided, comprising a first door body 201, a hinge as described above, or a hinge assembly 100 as described above, a guide member 4 adapted to be mounted on a vehicle body, and the first door body 201 is connected to the hinge body 1. The hinge enables the first door body 201 to move first and then rotate when switching from a closed position to an open position, thereby preventing the first door body 201 from interfering with adjacent components during the opening process.

[0100] The present disclosure does not limit the specific type of the door assembly 200. The door assembly 200 may be any door assembly 200 suitable for being arranged on a vehicle. For example, the door assembly 200 may be a tailgate assembly of the vehicle; or, the door assembly 200 may also be a door assembly on the side of the vehicle for a user to enter the passenger compartment; or, the door assembly 200 may also be a trunk door assembly on the side of a bus.

[0101] Optionally, the connecting rod 12 of the hinge body 1 is hinged to the mounting member 3, the guide member 4 is fixed to the mounting member 3, and the mounting member 3 is used to be connected to the vehicle body.

[0102] Alternatively, if Figures 8 to 10 As shown, the door assembly 200 further includes a second door body 202, and the first door body 201 and the second door body 202 are arranged side by side. In other words, the door assembly 200 is a split tailgate assembly, and the first door body 201 and the second door body 202 constitute a split vehicle tailgate. In the first motion state, the first door body 201 can move in a direction away from or close to the second door body 202 driven by the hinge body 1, and in the second motion state, the first door body 201 can rotate in a direction away from or close to the vehicle body driven by the hinge body 1.

[0103] The hinge assembly 100 can independently open or close the first door body 201 of the split vehicle tailgate, and when opening or closing the first door body 201, there is no need to open the second door body 202 in advance. That is to say, no matter what state the second door body 202 is in, whether it is open or closed, it will not affect the user's independent opening or closing of the first door body 201. As a result, the opening and closing process of the split vehicle tailgate is simplified, and the user experience is improved.

[0104] Optionally, the second door body 202 may also be connected to the hinge or hinge assembly 100, which is not limited in the present disclosure.

[0105] It should be noted that the present disclosure does not limit the specific connection relationship between the first door body 201 and the second door body 202. In order to make the split vehicle tailgate have a better sealing effect, optionally, as Figures 8 to 10 As shown, the side of the second door body 202 close to the first door body 201 is overlapped on the outside of the first door body 201. The second door body 202 overlapped on the outside of the first door body 201 can cover the gap between the first door body 201 and the second door body 202, so as to effectively prevent rainwater from penetrating from the gap between the first door body 201 and the second door body 202, and the split-type vehicle tailgate has better sealing performance.

[0106] Here, it should be noted that the present disclosure does not limit the specific positional relationship between the first door body 201 and the second door body 202 of the split tailgate. For example, the first door body 201 and the second door body 202 can be arranged relative to each other in the up-down direction (i.e., the height direction of the vehicle), and the first door body 201 is arranged below the second door body 202, that is, the first door body 201 is the lower tailgate, and the second door body 202 is the upper tailgate. The hinge assembly 100 provided in the present disclosure can be used for the lower tailgate; or, the first door body 201 is arranged above the second door body 202, the first door body 201 is the upper tailgate, and the second door body 202 is the lower tailgate. The hinge assembly 100 provided in the present disclosure can be used for the upper tailgate. When opening or closing the first door body 201, the first door body 201 can move in the up-down direction under the action of the hinge body 1.

[0107] The first door body 201 and the second door body 202 may also be spaced apart in the left-right direction. For example, the first door body 201 and the second door body 202 may be relatively arranged in the left-right direction (i.e., the width direction of the vehicle). In this way, when the first door body 201 is opened or closed, the first door body 201 can move in the left-right direction driven by the hinge body 1.

[0108] As an embodiment of the present disclosure, Figures 8 to 10 As shown, the first door body 201 and the second door body 202 are arranged in the up-down direction, wherein the first door body 201 is located below the second door body 202, or the first door body 201 is located above the second door body 202. In other words, the first door body 201 and the second door body 202 are arranged opposite to each other in the height direction of the vehicle, and the first door body 201 and the second door body 202 can form a sky and earth door.

[0109] According to a fourth aspect of the present disclosure, a vehicle is provided, comprising the hinge as described above, or the hinge assembly 100 as described above, or the door assembly 200 as described above.

[0110] The vehicle has all the beneficial effects of the above-mentioned hinge or hinge assembly 100 or door assembly 200, which will not be repeated here.

[0111] The present disclosure does not limit the type of vehicle, which may be a pure electric vehicle, a hybrid electric vehicle (extended-range vehicle), etc., and the present disclosure does not limit this.

[0112] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0113] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0114] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
