Description

Technical Field

[0001] This invention relates to the field of vehicle component technology, and in particular to a door hinge structure. Furthermore, this invention also relates to a door hinge assembly having the aforementioned door hinge structure, and a vehicle equipped with the assembly. Background Technology

[0002] Butterfly doors, also known as butterfly doors, have hinges mounted on the A-pillar or fender near the A-pillar of the car body. The doors open forward and upward through the hinges, and the angled upward opening of the doors is like the wings of a butterfly, hence the name "butterfly doors".

[0003] The opening and closing trajectory of butterfly doors is determined by the door hinges, and due to the different opening method, butterfly door hinges differ significantly in structure from ordinary sequential door hinges. Currently, traditional butterfly door hinges are generally large and non-removable, resulting in high maintenance costs. Furthermore, the door lock systems corresponding to butterfly door hinges and ordinary door hinges are not interchangeable, requiring the development of separate door lock systems for butterfly door hinges, which also leads to higher development costs.

[0004] Furthermore, existing butterfly door hinges still suffer from low door sag stiffness, which can easily cause the door to sag after prolonged use, affecting its normal operation. Additionally, existing butterfly door hinges often require two support rods to achieve electric opening and closing. One of these rods is a Y-axis (body width) auxiliary support rod, which provides a Y-axis opening force to ensure smooth unlocking when the door is initially opened and locked. However, the two-rod design undoubtedly increases vehicle cost significantly and also creates difficulties in component placement. Summary of the Invention

[0005] In view of this, the present invention aims to provide a door hinge structure that can reduce the number of struts, thereby reducing costs and simplifying component layout.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A door hinge structure, comprising:

[0008] A hinge base, on which a rotating connector is rotatably provided, and a swingable door connector is connected to the rotating connector, and a guide mechanism is provided between the door connector and the hinge base;

[0009] A drive structure is provided with a connection part that is connected to an external drive device, and a first actuating mechanism and a second actuating mechanism are provided between the drive structure and the door connector.

[0010] The first actuating mechanism is used to drive the door connector to swing relative to the rotating connector, the second actuating mechanism is used to drive the door connector to open the door, and the guiding mechanism is used to limit the opening trajectory of the door.

[0011] Furthermore, the hinge seat is provided with a mounting shaft, the rotating connector is disposed on the mounting shaft, and the door connector is rotatably connected to the rotating connector via the hinge shaft.

[0012] Furthermore, one end of the rotating connector is provided with a rotating connecting hole, and a rotating connecting arm is provided at the other end of the rotating connector relative to the rotating connecting hole; the rotating connector is connected to the mounting shaft through the rotating connecting hole, and the hinge shaft is connected to the rotating connecting arm.

[0013] Furthermore, the drive structure includes a drive fork, which is rotatably disposed relative to the hinge seat. The connecting portion is located on the drive fork, and the first actuating mechanism and the second actuating mechanism are disposed between the drive fork and the door connector; or,

[0014] The drive structure includes two drive members, which are rotatably disposed relative to the hinge seat. Each of the two drive members is provided with a connecting portion. The first actuating mechanism is disposed between one of the drive members and the door connector, and the second actuating mechanism is disposed between the other drive member and the door connector.

[0015] Furthermore, the drive fork is mounted on the mounting shaft, and the first actuation mechanism includes an actuation block mounted on the drive fork and a driven member mounted at one end of the door connector. The actuation block has an actuation surface, which is used to push against the driven member to drive the door connector to rotate around the hinge shaft.

[0016] Furthermore, the drive fork is provided with a mating block located on one side of the actuating block, and a mating surface is formed on the mating block. The mating surface and the actuating surface are arranged opposite to each other, and an actuating groove is formed between them. The driven member includes a first ball head connected to the door connector, and as the actuating surface pushes against it, the driven member slides out of the actuating groove.

[0017] Furthermore, the second actuating mechanism includes a shift fork disposed on the drive shift fork and a driven block disposed on the door connector; the shift fork can push against the driven block to drive the door connector to rotate the rotating connector around the mounting shaft.

[0018] Furthermore, the driven block and the driven member are located at the same end of the door connector.

[0019] Furthermore, the rotating connector, the door connector, and the drive fork are arranged sequentially along the axial direction of the mounting shaft, with one end of the mounting shaft connected to the hinge seat pointing to the other end.

[0020] Furthermore, the hinge seat is provided with a first limiting block and / or a second limiting block. The first limiting block can abut against one side of the rotating connector to limit the opening of the door, and the second limiting block can abut against the other side of the rotating connector to limit the closing of the door.

[0021] Furthermore, the guiding mechanism includes a guide rail disposed on the door connector and a sliding member disposed on the hinge seat, and the sliding member is constrained to slide along the guide rail groove on the guide rail.

[0022] Furthermore, the hinge seat is provided with a connecting boss, and the sliding member includes a second ball head connected to the connecting boss.

[0023] Furthermore, one end of the guide rail groove forms a limiting cavity, and when the sliding member is located in the limiting cavity, the sliding member abuts against the inner wall of the limiting cavity, thereby limiting the closing of the car door.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] The door hinge structure described in this invention, through the setting of the first actuating mechanism, can drive the door lock to disengage by the hinge itself when the door is opened, without the need for an auxiliary support rod for driving the door lock to disengage, thus reducing the number of support rods and helping to reduce hinge costs and component layout troubles.

[0026] Furthermore, the drive structure in this invention employs a drive fork, which boasts high structural integration, simplifies the hinge structure, and facilitates the arrangement of the drive structure. The use of two drive components further reduces design complexity. The first actuating mechanism utilizes a combination of an actuating block with an actuating surface and a driven component, resulting in a simple structure that is easy to design and manufacture. The ball-head structure of the driven component also ensures the smoothness of the actuating process of the first actuating mechanism. By setting a mating block to form an actuating groove, the overall stability of the hinge structure's movement is increased, thereby improving its performance.

[0027] Furthermore, the second actuating mechanism in this invention, employing a combination of a fork and a driven block, offers advantages such as simple structure and ease of design and manufacturing. The inclusion of the first and second limiting blocks not only ensures the precision of the door's opening and closing actions but also enhances the door's sag stiffness through the second limiting block. The ball-head structure of the sliding member increases its smoothness within the guide rail groove. A limiting cavity is formed at one end of the guide rail groove, allowing the sliding member to limit the door's closing position when positioned within this cavity. This achieves dual limiting of the closed door, further improving its sag stiffness.

[0028] The present invention also proposes a door hinge assembly, which includes the door hinge structure as described above, and also includes a drive component;

[0029] The drive component constitutes the external drive device, and one end of the drive component is connected to the hinge seat or the vehicle body, and the other end of the drive component has a retractable drive rod, the end of which is connected to the connecting part.

[0030] Furthermore, the present invention also proposes a vehicle in which the doors are mounted on the vehicle body via the aforementioned door hinge assembly.

[0031] The vehicle and door hinge assembly described in this invention have the same beneficial effects as the existing technology and the door hinge structure described above, which will not be repeated here. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0056] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] Example 1

[0058] This embodiment relates to a car door hinge structure, specifically a butterfly door hinge. In terms of overall structure, the car door hinge structure of this embodiment includes a hinge base 1 and a drive structure. A rotating connector 3 is rotatably provided on the hinge base 1, and a swingable car door connector 2 is connected to the rotating connector 3.

[0059] Furthermore, a guide mechanism is provided between the door connector 2 and the hinge seat 1, and a connection part connected to an external drive device is provided on the drive structure. At the same time, a first actuating mechanism and a second actuating mechanism are also provided between the drive structure and the door connector 2.

[0060] The first actuating mechanism is used to drive the door connector 2 to swing relative to the rotating connector 3 so as to unlock the door lock. The second actuating mechanism is used to drive the door connector 2 to open the door 14 after the door lock is unlocked. The guiding mechanism is used to limit the opening trajectory of the door 14 when the door 14 is opened.

[0061] In detail, an exemplary structure of the door hinge structure in this embodiment is as follows: Figures 1 to 3 As shown, and combined with Figure 4As shown, in this exemplary structure, the hinge base 1 is provided with a mounting shaft 101, the aforementioned rotating connector 3 is provided on the mounting shaft 101 and can rotate around the axis of the mounting shaft 101, and the door connector 2 is also rotatably connected to the rotating connector 3 through the hinge shaft 5.

[0062] Specifically, the hinge seat 1 is a plate-like structure with multiple body connection holes. The hinge seat 1 can be fixed to the body 13 by bolts passing through the body connection holes. The mounting shaft 101 is fixed to the hinge seat 1 by means such as welding, screwing, or interference fit. At the same time, along the axial direction of the mounting shaft 101, the mounting shaft 101 is also a stepped shaft with different diameters, and an external thread is formed on the outer circumferential surface of the middle part of the mounting shaft 101. A threaded hole is also provided at the end of the mounting shaft 101 away from the hinge seat 1.

[0063] In this embodiment, the structure of the door connector 2 is as follows: Figure 5 As shown, one end of the connector is provided with a door connection end 201, and a door connection hole is provided on the door connection end 201 for connecting the door connector 2 and the door 14 together by a screw connection structure. In order to realize the rotational connection between the door connector 2 and the rotating connector 3, a shaft hole 204 is also provided on the door connector 2. The aforementioned hinge shaft 5 passes through the shaft hole 204 to connect the door connector 2 and the rotating connector 3.

[0064] like Figure 6 In this embodiment, the rotating connector 3 has a rotating connection hole 301 at one end, through which it is connected to the mounting shaft 101. After the rotating connector 3 is fitted onto the mounting shaft 101 via the rotating connection hole 301, the nut 102 screwed onto the mounting shaft 101 can constrain the rotating connector 3 to a position close to the root of the mounting shaft 101, thereby achieving a limited mounting of the rotating connector 3 on the mounting shaft 101.

[0065] In contrast to the rotating connecting hole 301, this embodiment also forms a rotating connecting arm 302 at the other end of the rotating connecting member 3. As a preferred embodiment, there are two rotating connecting arms 302 arranged opposite to each other, and the two rotating connecting arms 302 are also provided with hinge holes 3021 arranged opposite to each other. After the hinge shaft 5 passes through the shaft hole 204 on the door connecting member 2, its two ends are distributed in the aforementioned hinge holes 3021. At the same time, the part of the door connecting member 2 connected to the hinge shaft 5 is also located between the two rotating connecting arms 302.

[0066] Thus, the hinge shaft 5 passes through the hinge holes 3021 at both ends and the shaft hole 204 in the middle, enabling the door connector 2 and the rotating connector 3 to be rotatably connected together. Furthermore, after the two ends of the hinge shaft 5 are respectively located in the two hinge holes 3021, they can generally be riveted to secure them to the rotating connector 3. Of course, besides riveting the hinge shaft 5, this embodiment can also use a bolt pair passing between the rotating connector 3 and the door connector 2, thus using the bolt pair as the shaft structure to achieve the same rotatable connection between the rotating connector 3 and the door connector 2.

[0067] It should be noted that, in addition to the rotating connector 3 being rotatably connected to the mounting shaft 101 via its own rotating connection hole 301, as another feasible implementation, the rotating connector 3 and the mounting shaft 101 can also be integrated together. This means that the rotating connector 3 and the mounting shaft 101 are a single integrated structure, and the mounting shaft 101 is rotatably connected to the hinge seat 1. In this case, the mounting shaft 101 can also be connected to the hinge seat 1 using a conventional rotating connection method.

[0068] In this embodiment, the drive structure described above can preferably be disposed on the hinge seat 1. However, it is understood that the drive structure can also be disposed in other locations within the vehicle body besides the hinge seat 1. Furthermore, as a feasible implementation, reference is still made to... Figures 1 to 3 As shown, the drive structure includes a drive fork 4, which is rotatably mounted relative to the hinge seat 1. The connecting part is located on the drive fork 4. At the same time, the first actuation mechanism and the second actuation mechanism are also disposed between the drive fork 4 and the door connector 2.

[0069] The specific structure of the aforementioned drive fork 4 is as follows: Figure 7 As shown, and similar to the aforementioned rotating connector 3, a pivot hole 406 is provided on the drive fork 4, through which the drive fork 4 is rotatably mounted on the mounting shaft 101. After the drive fork 4 is mounted on the mounting shaft 101, it can be constrained to a position close to the end of the mounting shaft 101 by means of bolts 8 screwed to the end of the mounting shaft 101, thereby achieving the same limited mounting of the drive fork 4 on the mounting shaft 101. Moreover, from one end of the mounting shaft 101 connected to the hinge seat 1 to the other end, the rotating connector 3, the door connector 2, and the drive fork 4 in this embodiment are also arranged sequentially along the axial direction of the mounting shaft 101.

[0070] At the same time, it should be noted that the drive fork 4 in this embodiment is generally similar to a horizontal "V" shaped structure. The aforementioned connection part for connecting with the external drive device is provided at one end of the drive fork 4. Specifically, the connection part adopts a connection hole 402 opened on the drive fork 4.

[0071] Furthermore, as an exemplary implementation, combined with Figure 5 and Figure 7 As shown, the first actuating mechanism in this embodiment specifically includes an actuating block 403 disposed on the drive fork 4 and a driven member 203 disposed at one end of the door connector 2. An actuating surface 405 is formed on the actuating block 403, and... Figure 7 Based on the orientation shown, the actuating surface 405 is a curved surface with its top inclined towards the hinge seat 1 on the side facing the drive fork 4. By utilizing this curved actuating surface 405 with its top inclined towards the hinge seat 1, when the drive fork 4 rotates around the mounting shaft 101 under the driving force of the external drive device, the actuating surface 405 can push against the driven member 203, so that the door connector 2 can rotate around the hinge shaft 5.

[0072] It should be noted that, in addition to setting it as a curved surface, setting the actuating surface 405 as an inclined surface with its top sloping towards the side of the drive fork 4 facing the hinge seat 1 is also possible. Furthermore, to increase the overall smoothness of the hinge structure's movement, this embodiment, as a preferred embodiment, also provides a mating block 404 located on one side of the actuating block 403 on the drive fork 4. The mating block 404 has a mating surface formed on it, which is arranged opposite to the actuating surface 405, and can generally be set as the same curved surface or inclined surface as the actuating surface 405. Thus, this embodiment can form an actuating groove between the actuating surface 405 and the mating surface, and as the actuating surface 405 pushes against the driven member 203, the driven member 203 gradually slides out of the actuating groove.

[0073] During the process of the driven member 203 sliding out of the aforementioned actuating groove, the driven member 203 not only abuts against the actuating surface 405 to withstand the pushing force of the actuating surface 405, but also abuts against the mating surface on the mating block 404 and slides along the mating surface. By having the driven member 203 simultaneously abut against the actuating surfaces 405 on both sides and the mating surface, the aforementioned effect of increasing the overall smoothness of the hinge structure's movement is achieved.

[0074] In this embodiment, as a preferred implementation, the follower 203 specifically includes a first ball joint connected to the door connector 2. By making the follower 203 adopt a ball joint structure, the smoothness of the first actuation mechanism's actuation process can be guaranteed.

[0075] Still combined Figure 5 and Figure 7As shown, the second actuating mechanism in this embodiment specifically includes a shift fork 401 disposed on the drive shift fork 4 and a driven block 202 disposed on the door connector 2. The driven block 202 and the driven member 203 are located at the same end of the door connector 2. In this embodiment, after the door 14 is unlocked, the shift fork 401 can push against the driven block 202, so that the door connector 2 drives the rotating connector 3 to rotate around the mounting shaft 101.

[0076] At this point, in order to unlock door 14, the shift fork 401 pushes against the driven block 202, as shown in the reference. Figure 1 As shown in the illustration, in this embodiment, when the car door 14 is in the closed state and the driven member 203 in the first actuation mechanism is at the bottom of the actuation groove, there is a gap d between the fork 401 in the second actuation mechanism and the driven block 202. Furthermore, during the process of driving the fork 4 to rotate, causing the first actuation mechanism to operate, that is, causing the actuation surface 405 on the actuation block 403 to push against the driven member 203 to unlock the car door, simultaneously, the fork 401 moves past the gap d and approaches the driven block 202 as the driving fork 4 rotates. When the car door is unlocked, the driven member 203 slides out of the actuation groove, disengaging from the actuation surface 405, and the fork 401 then contacts the driven block 202. Subsequently, as the driving fork 4 rotates further, it can drive the door connector 2 to open the car door 14.

[0077] In this embodiment, the driven block 202 is specifically a protruding structure integrally formed on the door connector 2, and the shift fork 401 is a cantilever structure on the drive shift fork 4. In order to increase the structural strength of the shift fork 401 on the drive shift fork 4, flanges are also formed on both sides of the shift fork 401, and the flanges on both sides extend to the root of the shift fork 401.

[0078] Additionally, it should be noted that besides mounting the drive fork 4 on the mounting shaft 101, the drive fork 4 can also be mounted on another shaft parallel to the mounting shaft 101, instead of being coaxially mounted with the rotating connector 3. In this case, the other shaft can still be mounted on the hinge seat 1, or it can be mounted in another position other than the hinge seat 1, so as to achieve the rotatable mounting of the drive fork 4 and the mutual cooperation between the drive fork 4 and the door connector 2.

[0079] This embodiment uses only a drive fork 4 for the drive structure, and thus both the first and second actuation mechanisms are located between the drive fork 4 and the door connector 2. In this way, the external drive device is simply a single drive component (e.g., an electric strut) connected to the drive fork 4. When the door is opened, the hinge itself, i.e., the first actuation mechanism, can disengage the door lock. After the door lock is disengaged, the external drive device can still drive the drive fork 3 to continue opening the door 14 via the second actuation mechanism. Therefore, by using the drive fork 4 for the drive structure, it is unnecessary to provide an auxiliary strut for disengaging the door lock in practice. This reduces the number of struts, which helps to reduce hinge costs and simplify component placement.

[0080] However, it should be noted that, in addition to adopting the drive fork 4 described above in the drive structure, the drive structure of this embodiment can still adopt other implementation forms in specific implementations. For example, the drive structure of this embodiment can still include two drive members, which are also rotatably arranged relative to the hinge seat 1. Each of the two drive members is provided with a connecting part, and the first actuating mechanism is arranged between one of its drive members and the door connector 2, while the second actuating mechanism is arranged between the other drive member and the door connector 2.

[0081] When the drive structure uses two drive components, the external drive device connected to them can still be only one drive component (e.g., an electric strut), and the drive end of the drive component can be linked with the two drive components. In this way, the external drive device can drive the two drive components simultaneously (still with the above-mentioned distance d) or sequentially (without the above-mentioned distance d). The two drive components can then cooperate with the driven component 203 and driven block 202 on the door connector 2 sequentially. This can also reduce the number of struts and help reduce hinge costs and component layout troubles.

[0082] However, it is undeniable that, aside from still using only one driving component for the external drive device, it is also feasible to use two driving components (e.g., two struts, one of which is an auxiliary strut) to drive the two driving components separately when the drive structure uses two driving components, similar to the existing door hinge drive structure. In this embodiment, it is preferred that the external drive device still uses only one driving component.

[0083] Furthermore, regarding the structure of the two driving components, referring to the aforementioned drive fork 4, the two driving components also divide the aforementioned drive fork 4 into two parts. Each of these two parts is provided with a rotating connection structure such as a pivot hole 406, and both are mounted on the mounting shaft 101 or on another shaft parallel to the mounting shaft 101 via the rotating connection structure. Meanwhile, the connecting portions on both parts can still adopt the same structure as the connecting hole 402. One part is provided with a toggle block 403 and a mating block 404 that cooperate with the driven member 203 to form a first actuating mechanism, while the other part is provided with a fork 401 that cooperates with the driven block 202 to form a second actuating mechanism.

[0084] Combined with Figure 4 and Figure 6 As shown in the preferred embodiment, this model also includes a first limiting block 9 and a second limiting block 10 on the hinge base 1. The first limiting block 9 and the second limiting block 10 are fixed to the hinge base 1 by means of screws or welding. The first limiting block 9 abuts against one side of the rotating connector 3 to specifically limit the opening of the door 14, while the second limiting block 10 abuts against the other side of the rotating connector 3 to specifically limit the closing of the door 14. Simultaneously, the two limiting blocks achieve their respective limiting effects through abutment with the first limiting surface 303 and the second limiting surface 304 on both sides of the rotating connector 3.

[0085] By setting the two limiting blocks mentioned above, not only can the accuracy of the opening and closing action of the door 14 be guaranteed, but also, by using the second limiting block 10, this embodiment can particularly improve the sag stiffness of the door 14, thereby ensuring the quality of use of the door 14. While both the first limiting block 9 and the second limiting block 10 are provided, it should be noted that this embodiment can also use only one of the two limiting blocks, and in specific implementation, it is preferable to ensure that the second limiting block 10 is provided.

[0086] This embodiment is referred to again. Figure 5 As shown, the aforementioned guiding mechanism specifically includes a guide rail 6 disposed on the door connector 2 and a slider 104 disposed on the hinge seat 1, and the slider 104 is constrained to slide along the guide rail groove 601 on the guide rail 6.

[0087] In this preferred embodiment, the guide rail 6 can be detachably fixed to the door connector 2, for example, by a plurality of screws 7. Furthermore, the guide rail 6, fixed by screws 7, together with the aforementioned rotating connector 3 constrained and limited by a screwed nut 102, and the drive fork 4 constrained and limited by bolts 8, enables the detachable design of the hinge structure components in this embodiment, thereby facilitating hinge assembly and subsequent maintenance.

[0088] In this embodiment, a connecting boss 103 is also provided on the hinge seat 1, and the aforementioned sliding member 104 can be a second ball joint connected to the connecting boss 103. The sliding member 104 with the second ball joint can enter the guide rail groove 601 through one open end of the guide rail groove 601. In this embodiment, by adopting a ball joint structure, the smoothness of sliding of the sliding member 104 in the guide rail groove 601 can also be increased.

[0089] In addition, this embodiment can also be configured such that one end of the guide rail groove 601 forms a limiting cavity 602. In this case, the end of the guide rail groove 601 forming the limiting cavity 602 is specifically configured to be closed, and the guide rail groove 601 at the location of the limiting cavity 602 is also basically horizontal. Thus, when the sliding member 104 is located at the limiting cavity 602, the sliding member 104 can abut against the inner wall of the limiting cavity 602, similar to the function of the second limiting block 10 mentioned above, to limit the closing of the door 14, thereby achieving a double limiting effect.

[0090] In this embodiment, the door hinge structure, when in use, is in the closed state as follows: Figures 1 to 3 as well as Figure 8 As shown, in the closed state, the hinge shaft 5 is arranged along the Z direction, that is, the vehicle height direction. The driven member 203 on the door connector 2 is located at the bottom of the shift groove. There is a distance d between the shift fork 401 on the drive fork 4 and the driven block 202 on the door connector 2. The second limiting surface 304 on the rotating connector 3 abuts against the second limiting block 10. The sliding member 104 is located at the limiting cavity 602 at one end of the guide rail groove 601. Together, they form a limiting force on the door connector 2.

[0091] When the drive fork 4 starts to rotate under the driving force of the external drive unit to unlock the door 14, Figure 8 With the indicated orientation as a reference, the drive fork 4 is driven to rotate counterclockwise. Due to the presence of gap d, the actuating block 403 on the drive fork 4 uses its actuating surface 405 to push against the driven member 203. At this time, under the limiting action of the second limiting block 10, the door connector 2 can only rotate around the hinge axis 5, thereby driving the door 14 to move in the Y direction, that is, in the vehicle width direction, thus realizing the unlocking of the door lock.

[0092] After the door lock is unlocked, the driven member 203 slides out of the actuation groove, and the shift fork 401 is in contact with the driven block 202. As the drive shift fork 4 rotates further counterclockwise, the shift fork 401 drives the door connector 2 via the driven block 202. The door connector 2 drives the door 14 to open, and the opening trajectory is determined by the sliding member 104 sliding along the guide rail groove 601. At the same time as the door opens, the door connector 2 also drives the rotating connector 3 to rotate synchronously around the mounting shaft 101 via the hinge shaft 5. When the first limiting surface 303 on the rotating connector 3 abuts against the first limiting block 9, the door 14 is opened to the correct position. After the door is opened to the correct position, the hinge structure can... Figure 9 As shown in the image.

[0093] When the door 14 returns from the open state to the closed state, the above process is repeated in reverse. Furthermore, the door hinge structure of this embodiment, through the setting of the first actuating mechanism, allows the door lock to be disengaged by the hinge's own structure, i.e., the actuating block 403 on the drive fork 4, when the door 14 is opened. This eliminates the need for auxiliary support rods to disengage the door lock, thereby reducing the number of support rods and simplifying hinge cost and component layout. Simultaneously, since the hinge also rotates in a plane around the Z-axis hinge axis 5 under the push of the actuating block 403 during the initial opening phase, its movement trajectory is the same as that of a conventional forward-opening door hinge. Therefore, the door hinge structure of this embodiment can also be interchanged with door lock systems using conventional forward-opening hinges, thus improving the versatility of the hinge structure.

[0094] Example 2

[0095] This embodiment relates to a door hinge assembly, such as Figure 10 As shown, it includes the door hinge structure in Embodiment 1, and also includes a drive component 11.

[0096] The drive component 11 constitutes the external drive device described in Embodiment 1. One end of the drive component 11 is connected to the hinge seat 1 or the vehicle body 13, and the other end of the drive component 11 has a telescopic drive rod. The end of the drive rod is connected to the connecting part on the drive structure.

[0097] Specifically, as a preferred implementation method, such as Figure 11 and Figure 12 As shown, one end of the drive component 11 is connected to the vehicle body 13, and a mounting bracket 12 can be installed at the A-pillar or fender of the vehicle body 13. The bottom end of the drive component 11 can be connected to the mounting bracket 12 via a ball joint. In addition, the end of the drive rod can also be connected to the connection hole 402 on the drive fork 4 via a ball joint.

[0098] In addition, as a preferred embodiment, the drive component 11 in this embodiment can be an electric strut, which enables automatic raising and lowering of the door 14 during opening and closing, and also allows for stopping the opening and closing process at any time. Of course, in addition to an electric strut, the drive component 11 can also be other drive devices capable of automatically opening and closing the door 14.

[0099] The schematic diagrams of the door hinge assembly in this embodiment, under the drive of the drive member 11, showing the hinge structure in closed and open states, can be seen respectively. Figure 11 and Figure 12 Furthermore, the specific operation process of the hinge structure under the drive of the drive component 11 can be found in the relevant description in Embodiment 1.

[0100] The door hinge assembly of this embodiment adopts the door hinge structure in Embodiment 1, which can reduce the number of support rods, thereby reducing hinge costs and the hassle of component layout. It can also be interchanged with door lock systems that use ordinary forward-opening hinges, improving the versatility of the hinge structure and making it very practical.

[0101] Example 3

[0102] This embodiment relates to a vehicle, such as Figure 13 As shown, the door 14 in the vehicle is mounted on the body 13 via the door hinge assembly in Embodiment 2.

[0103] The vehicle in this embodiment uses the door hinge assembly in Embodiment 2, which enables the butterfly door to open when the door 14 is opened, thus enhancing the vehicle's technological feel. At the same time, by using the door hinge assembly in Embodiment 2, this embodiment can reduce the number of hinge assembly parts, thereby reducing hinge costs and the hassle of component layout, and also improving the versatility of the hinge structure, thus having good practicality.

[0104] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
