[0030] Reference below Figure 1-Figure 7 A vehicle door hinge assembly 100 according to an embodiment of the present invention is described. The vehicle door hinge assembly 100 can realize the oblique upward opening of the vehicle door 300, has a simple structure, is easy to install and disassemble, is highly compact, occupies a small space, is easy to arrange and install on the vehicle body 200, and the transmission component 32 has high transmission efficiency and good transmission stability, making the opening and closing process of the vehicle door 300 more stable and reliable, and providing a better user experience.

[0031] like Figure 1-Figure 7 As shown, a vehicle door hinge assembly 100 according to one embodiment of the present invention includes: a first mounting member 1 , a second mounting member 2 and a driving mechanism 3 .

[0032] The first mounting member 1 is used to be connected to the vehicle body 200, and the second mounting member 2 is used to be connected to the vehicle door 300. In practice, the first mounting member 1 and the vehicle body 200 can be connected by screws, bolts and other threaded connections to achieve a fixed connection between the first mounting member 1 and the vehicle body 200, and the second mounting member 2 and the vehicle door 300 can also be connected by screws, bolts and other threaded connections to achieve a fixed connection between the second mounting member 2 and the vehicle door 300, so that the first mounting member 1 and the vehicle body 200 are connected as an integral structure, and the second mounting member 2 and the vehicle door 300 are connected as an integral structure. Of course, the first mounting member 1 and the vehicle body 200, and the second mounting member 2 and the vehicle door 300 can also be connected by other connection methods such as clamping and welding, which are flexible and optional and not limited to those described in this embodiment.

[0033] In this way, the first mounting member 1 is firmly connected to the vehicle body 200, and the second mounting member 2 is firmly connected to the vehicle door 300. When the second mounting member 2 moves relative to the first mounting member 1, the second mounting member 2 can drive the vehicle door 300 to move stably together, thereby realizing the movement of the vehicle door 300 relative to the vehicle body 200 and realizing the stable opening and closing of the vehicle door 300.

[0034] Furthermore, the door hinge assembly 100 includes a drive mechanism 3 for driving the second mounting member 2 to move relative to the first mounting member 1. The drive mechanism 3 includes a drive member 31 and a transmission assembly 32. The transmission assembly 32 is mounted on the first mounting member 1. The drive member 31 is power-connected to the second mounting member 2 via the transmission assembly 32 to drive the second mounting member 2 to move relative to the first mounting member 1 in two directions.

[0035] That is to say, the driving member 31 is used to provide power to drive the transmission component 32 to move. When the transmission component 32 moves, it drives the second mounting member 2 to move relative to the first mounting member 1, thereby realizing power transmission from the driving member 31 to the second mounting member 2, and realizing the opening and closing of the vehicle door 300 relative to the vehicle body 200.

[0036] Among them, the second mounting member 2 moves in two directions relative to the first mounting member 1, and the two directions can be the up and down directions of the vehicle and the inside and outside directions of the vehicle, that is, the driving member 31 can drive the second mounting member 2 to move in the up and down directions and the inside and outside directions relative to the first mounting member 1, so that the vehicle door 300 can move in the up and down directions and the inside and outside directions of the vehicle relative to the vehicle body 200, thereby realizing the oblique upward opening of the vehicle door 300, that is, opening toward the outside while also opening upward and closing the vehicle door 300.

[0037] It can be understood that in the actual process of opening the car door 300, the second mounting member 2 drives the car door 300 to move outward and upward relative to the car body 200 until it moves to a certain range, thereby realizing the oblique upward opening of the car door 300. In the process of closing the car door 300, the second mounting member 2 drives the car door 300 to move inward and downward relative to the car body 200 until it moves to a certain range, the car door 300 and the car body 200 are in the same plane, and the car door 300 completely closes the car body 200, thereby realizing the oblique downward closing of the car door 300.

[0038] In actual design, the driving member 31 can be set as a driving motor, electric strut, hydraulic cylinder, hydraulic strut or other driving structures, and the transmission component 32 can be set as a gear transmission component, or a gear rack transmission component, or a gear and cam structure transmission component, etc.

[0039] In the prior art, the opening and closing of the vehicle door 300 is achieved through a multi-link mechanism, in which multiple axes intersect at one or two points, and extremely high manufacturing precision and assembly precision are required. Otherwise, undesirable phenomena such as the mechanism moving unsmoothly or getting stuck are likely to occur. At the same time, the structure is complex, there are many parts, and the space occupied is large. There are many restrictions and constraints on the layout space of the vehicle body side, that is, the vehicle body 200. The design and layout are difficult, and it is not easy to quickly assemble and adjust the door hinge assembly 100.

[0040] The door hinge assembly 100 of the present application can realize the opening and closing of the door 300 based on a set of driving mechanism 3. In the driving mechanism 3, the driving member 31 drives the second mounting member 2 to move in two directions relative to the first mounting member 1 through the transmission component 32 to realize the opening and closing of the door 300. It has a simple structure, is easy to install and disassemble, is highly compact, occupies a small space, is easy to arrange and install on the vehicle body 200, and the transmission component 32 has high transmission efficiency and good transmission stability, making the opening and closing process of the door 300 more stable and reliable, and providing a better user experience.

[0041] According to the vehicle door hinge assembly 100 of an embodiment of the present invention, a driving mechanism 3 including a driving member 31 and a transmission component 32 is provided. The driving member 31 drives the second mounting member 2 to move in two directions relative to the first mounting member 1 through the transmission component 32 to realize the opening and closing of the vehicle door 300. It has a simple structure, is easy to install and disassemble, is highly compact, occupies a small space, is easy to arrange and install on the vehicle body 200, and the transmission component 32 has high transmission efficiency and good transmission stability, so that the opening and closing process of the vehicle door 300 is more stable and reliable, and the user experience is better.

[0042] In some embodiments, the transmission assembly 32 includes a transmission arm 321, the driving member 31 is used to drive the transmission arm 321 to rotate, the second mounting member 2 is rotatably connected to the transmission arm 321, and the second mounting member 2 is dynamically connected to the transmission arm 321 so that the second mounting member 2 rotates relative to the transmission arm 321 while the second mounting member 2 rotates with the transmission arm 321.

[0043] That is to say, the output end of the driving member 31 is connected to the transmission arm 321 to provide power to the transmission arm 321, driving the transmission arm 321 to rotate, and the second mounting member 2 is connected to the transmission arm 321 power so that when the transmission arm 321 rotates, it can drive the second mounting member 2 to rotate, thereby transmitting power to the second mounting member 2 to realize the rotational movement of the second mounting member 2. At the same time, the second mounting member 2 is connected to the transmission arm 321 and can rotate relative to the transmission arm 321, so that the second mounting member 2 rotates relative to the transmission arm 321 while rotating with the transmission arm 321, thereby realizing the rotation of the second mounting member 2 in two directions relative to the first mounting member 1.

[0044] Specifically, if Figure 1 、 Figure 2 and Figure 4 As shown, the transmission assembly 32 includes a transmission arm 321, the transmission arm 321 is rotatably connected to the transmission arm 321, and the second mounting member 2 is dynamically connected to the transmission arm 321, as shown in FIG. Figure 2 and Figure 4 As shown in the up-down direction and the inside-outside direction, when the driving member 31 drives the transmission arm 321 to rotate upward (clockwise as seen in the figure), the second mounting member 2 rotates upward together with the transmission arm 321 (clockwise as seen in the figure), so that while the second mounting member 2 rotates upward, the second mounting member 2 also rotates outward relative to the transmission arm 321 (counterclockwise as seen in the figure), thereby causing the second mounting member 2 to rotate upward and outward relative to the first mounting member 1, thereby realizing the opening of the vehicle door 300.

[0045] Correspondingly, when the driving member 31 drives the transmission arm 321 to rotate downward (counterclockwise as seen in the figure), the second mounting member 2 rotates downward together with the transmission arm 321 (counterclockwise as seen in the figure), so that while the second mounting member 2 rotates downward, the second mounting member 2 also rotates inward relative to the transmission arm 321 (clockwise as seen in the figure), thereby causing the second mounting member 2 to rotate upward and inward relative to the first mounting member 1, thereby achieving the closing of the vehicle door 300.

[0046] In some embodiments, the transmission arm 321 is rotatably mounted on the first mounting member 1 around a first axis, and the second mounting member 2 is rotatably connected to the transmission arm 321 around a second axis. The first axis and the second axis are not in the same plane.

[0047] Specifically, the first axis can be located in a horizontal plane, and the second axis can be located in a plane intersecting the horizontal plane. For example, the second axis can be located in a vertical plane or other plane, so that the extension directions of the first axis and the second axis are different, and the second mounting member 2 can be moved in two directions relative to the first mounting member 1.

[0048] Among them, the transmission arm 321 is rotatably mounted on the first mounting member 1 around a first axis, that is, the transmission arm 321 is mounted on the first mounting member 1 and can rotate around the first axis relative to the first mounting member 1, and the second mounting member 2 is rotatably connected to the transmission arm 321 around a second axis, that is, the second mounting member 2 is connected to the transmission arm 321 and can rotate around the second axis relative to the transmission arm 321. In this way, when the transmission arm 321 rotates around the first axis relative to the first mounting member 1, it can drive the second mounting member 2 to rotate around the first axis together. At the same time, the second mounting member 2 will also rotate around the second axis relative to the transmission arm 321, so that the second mounting member 2 rotates around the second axis while rotating around the first axis relative to the first mounting member 1, thereby realizing the movement of the second mounting member 2 in two directions relative to the first mounting member 1.

[0049] In a specific embodiment, Figure 2 and Figure 4 As shown, the first axis is located in the horizontal plane and is also the lateral extension of the vehicle along the inward and outward directions of the vehicle, so that the transmission arm 321 can rotate in the vertical plane. The second axis is located in the vertical plane and extends along the up and down directions of the vehicle, so that the second mounting member 2 can rotate in the horizontal plane. In this way, when the driving member 31 drives the transmission arm 321 to rotate upward around the first axis (clockwise rotation as seen in the figure), the second mounting member 2 rotates upward around the first axis together with the transmission arm 321 (clockwise rotation as seen in the figure), so that while the second mounting member 2 rotates upward, the second mounting member 2 will also rotate outward around the second axis relative to the transmission arm 321 (counterclockwise rotation as seen in the figure), so that the second mounting member 2 rotates upward around the first axis and outward around the second axis relative to the first mounting member 1, thereby realizing the oblique upward opening of the vehicle door 300.

[0050] Correspondingly, when the driving member 31 drives the transmission arm 321 to rotate downward around the first axis (counterclockwise as seen in the figure), the second mounting member 2 rotates downward around the first axis together with the transmission arm 321 (counterclockwise as seen in the figure), so that while the second mounting member 2 rotates downward, the second mounting member 2 also rotates inward around the second axis relative to the transmission arm 321 (clockwise as seen in the figure), thereby causing the second mounting member 2 to rotate upward around the first axis and inward around the second axis relative to the first mounting member 1, thereby achieving the closing of the vehicle door 300.

[0051] In actual design, Figure 5As shown, a first mounting hole 41 may be provided on the first mounting member 1, as shown in FIG. Figure 2-Figure 4 As shown, the first rotating shaft 44 can be fixedly installed in the first mounting hole 41, and the axis of the first rotating shaft 44 is the first axis. Figure 6 As shown, a first through hole 43 can be provided on the transmission arm 321, and a first rotating shaft 44 can be passed through the first through hole 43, so that the transmission arm 321 can flexibly rotate around the first rotating shaft 44, thereby realizing that the transmission arm 321 is rotatably installed on the first mounting member 1 around the first axis.

[0052] In some embodiments, the transmission assembly 32 also includes a transmission gear 322, which is rotatably mounted on the transmission arm 321. The transmission gear 322 is configured to rotate while rotating around the first axis along with the transmission arm 321, and the transmission gear 322 is dynamically connected to the second mounting member 2 to drive the second mounting member 2 to rotate around the second axis when rotating.

[0053] That is, the transmission gear 322 is mounted on the transmission arm 321 to ensure the installation stability of the transmission gear 322, and the transmission gear 322 is rotatable relative to the transmission gear 322. In other words, the transmission gear 322 can rotate on the transmission arm 321 to achieve relative rotation between the transmission gear 322 and the transmission arm 321. The transmission gear 322 is power-connected to the second mounting member 2. That is, when the transmission gear 322 rotates, it can drive the second mounting member 2 to rotate, thereby achieving power transmission from the transmission gear 322 to the second mounting member 2. Therefore, when the transmission arm 321 rotates about the first axis, the transmission gear 322 rotates. When the transmission gear 322 rotates, it can drive the second mounting member 2 to rotate about the second axis, thereby achieving rotation of the vehicle door 300 about the second rotation axis 45, and realizing the upward opening of the vehicle door 300.

[0054] In actual design, the transmission gear 322 and the second mounting member 2 can be connected to each other through other gears, worm gears, cam structures, gear racks and other transmission structures, which are flexible and optional and are not limited to those described in this embodiment.

[0055] Specifically, if Figures 1-4 As shown, the transmission assembly 32 further includes a transmission gear 322, which rotates around the second rotation shaft 45. Figure 6 As shown, a second mounting hole 42 can be provided on the transmission arm 321, the second rotating shaft 45 can be fixedly installed in the second mounting hole 42, and the transmission gear 322 can be sleeved outside the second rotating shaft 45 and rotate around the second rotating shaft 45, so that the transmission gear 322 can be rotatably installed on the transmission arm 321, and the transmission gear 322 can rotate.

[0056] In some embodiments, the transmission assembly 32 also includes a mating gear 323, which is fixedly mounted on the first mounting member 1. The axis of the mating gear 323 coincides with the first axis. The mating gear 323 is engaged with the transmission gear 322. The transmission gear 322 is configured to rotate under the action of the mating gear 323 when rotating with the transmission arm 321.

[0057] That is to say, when the transmission arm 321 rotates around the first axis, the transmission gear 322 rotates around the first axis along with the transmission arm 321. Since the mating gear 323 is engaged with the transmission gear 322 and the mating gear 323 is fixed, the transmission gear 322 rotates around the first axis along with the transmission arm 321 under the action of the mating gear 323. In other words, when the transmission arm 321 rotates around the first axis, the transmission gear 322 both revolves around the mating gear 323 and rotates on its own, so as to transmit power to the second mounting member 2 during the rotation, thereby driving the second mounting member 2 to rotate around the second axis.

[0058] In a specific embodiment, Figures 1-4 As shown, the mating gear 323 can be sleeved on the outside of the first rotating shaft 44 and fixedly connected to the first rotating shaft 44, so that the mating gear 323 is fixedly installed on the first mounting member 1, so that the axis of the mating gear 323 is the axis of the first rotating shaft 44, that is, the axis of the mating gear 323 coincides with the first axis, and the mating gear 323 is meshed with the transmission gear 322, so that the transmission gear 322 can rotate under the drive of the mating gear 323 when it rotates with the transmission arm 321.

[0059] In actual design, an internal thread can be set inside the mating gear 323, and an external thread matching the internal thread can be set on the outer peripheral wall of the first rotating shaft 44 to achieve threaded fixation of the mating gear 323 and the first rotating shaft 44. Of course, the mating gear 323 and the first rotating shaft 44 can also be fixedly connected by keyway fixation, clamping fixation, welding fixation, one-piece molding, etc., which is flexible and optional and is not limited to what is described in this embodiment. It can be flexibly set according to actual needs.

[0060] In some embodiments, the transmission assembly 32 also includes a transmission rod 324, the second mounting member 2 is rotatably connected to the transmission arm 321 through a transmission shaft 325, one end of the transmission rod 324 is eccentrically connected to the transmission gear 322, and the other end of the transmission rod 324 is movably connected to the transmission shaft 325 to drive the second mounting member 2 to rotate relative to the transmission arm 321.

[0061] That is to say, the transmission rod 324 is connected to the transmission arm 321 and is rotatable relative to the transmission arm 321, that is, the transmission rod 324 and the transmission arm 321 can rotate relative to each other, wherein one end of the transmission rod 324 is eccentrically connected to the transmission gear 322, so that when the transmission gear 322 rotates, the transmission rod 324 can move along a certain trajectory, and the other end of the transmission rod 324 is movably connected to the transmission shaft 325, that is, the transmission rod 324 is connected to the transmission shaft 325 and is movable relative to the transmission shaft 325. Therefore, the transmission rod 324 is connected between the transmission gear 322 and the rotating shaft, and when the transmission gear 322 rotates, the transmission gear 322 will drive the transmission rod 324 to move along a certain trajectory relative to the transmission shaft 325, and then when the transmission rod 324 moves, it will drive the second mounting member 2 to rotate relative to the transmission arm 321, thereby realizing the outward opening and inward closing of the car door 300.

[0062] Specifically, if Figures 1-4 As shown, the transmission assembly 32 also includes a transmission rod 324, one end of the transmission rod 324 is bent and extended toward the transmission gear 322 to be fixedly connected to the transmission gear 322, and can be connected by welding, threaded connection, clamping, plug-in connection and other connection methods, so that one end of the transmission rod 324 is connected to the transmission gear 322 as an integral structure. When the transmission gear 322 rotates around the first axis, it can stably drive the transmission rod 324 to rotate around the first axis, and when the transmission gear 322 rotates, it can stably drive the transmission rod 324 to perform eccentric movement to drive the transmission shaft 325 to rotate. When the transmission shaft 325 rotates, it will drive the second mounting member 2 to rotate relative to the transmission arm 321, thereby realizing the outward opening and inward closing of the vehicle door 300.

[0063] In some embodiments, a sliding guide column 3241 is provided at the other end of the transmission rod 324, and a sliding guide groove 32511 is provided on the outer wall of the transmission shaft 325. The sliding guide column 3241 is slidably installed in the sliding guide groove 32511 to drive the transmission shaft 325 to rotate around the second axis.

[0064] Specifically, if Figure 2 As shown, a sliding guide column 3241 is provided at the other end of the transmission rod 324 away from the transmission gear 322, and a sliding guide groove 32511 is provided on the outer peripheral wall of the transmission shaft 325. The sliding guide groove 32511 extends along the circumference of the transmission shaft 325 and is inclined along the axial direction of the transmission shaft 325, and the shape and size of the sliding guide groove 32511 are adapted to the shape and size of the sliding guide column 3241, so that the sliding guide column 3241 can extend into the sliding guide groove 32511 and slide along the sliding guide groove 32511.

[0065] Therefore, when the transmission gear 322 rotates, the transmission gear 322 can drive the sliding guide column 3241 at the other end of the transmission rod 324 to slide along the extension direction of the sliding guide groove 32511, so as to drive the transmission shaft 325 to rotate around the second axis. When the transmission shaft 325 rotates, it will drive the second mounting member 2 to rotate relative to the transmission arm 321 along the inward and outward directions of the vehicle, thereby realizing the outward opening and inward closing of the door 300.

[0066] Among them, the transmission shaft 325 is driven to rotate around the second axis by sliding the sliding guide column 3241 in the sliding guide groove 32511, so that the transmission rod 324 moves smoothly and the transmission shaft 325 can rotate stably, reducing the use of parts, making the structure of the door hinge assembly 100 simpler and more compact, further reducing the space occupied by the door hinge assembly 100, and facilitating the installation of the door hinge assembly 100 on the vehicle body 200.

[0067] In practice, Figure 2 and Figure 4 As shown, when the transmission arm 321 rotates upward around the first axis (clockwise as seen in the figure), it drives the transmission shaft 325 and the transmission gear 322 to rotate upward around the first axis (clockwise as seen in the figure). When the transmission shaft 325 rotates around the first axis, it drives the vehicle door 300 to rotate around the first axis together, so as to realize the upward opening of the vehicle door 300. In the process of the transmission gear 322 rotating upward, the transmission gear 322 also rotates on itself (counterclockwise as seen in the figure), so that the sliding guide column 3241 at the other end of the transmission rod 324 slides downward along the sliding guide groove 32511, so as to drive the transmission shaft 325 to rotate outward around the second axis (counterclockwise as seen in the figure). When the transmission shaft 325 rotates around the second axis, it drives the vehicle door 300 to rotate around the second axis together, so as to realize the upward opening of the vehicle door 300, thereby realizing the oblique upward opening of the vehicle door 300.

[0068] Correspondingly, when the transmission arm 321 rotates downwardly around the first axis (counterclockwise as seen in the figure), it drives the rotating shaft and the transmission gear 322 to rotate upwardly around the first axis (counterclockwise as seen in the figure). When the transmission shaft 325 rotates around the first axis, it drives the vehicle door 300 to rotate around the first axis together, so as to realize the downward closing of the vehicle door 300. In the process of the transmission gear 322 rotating upward, the transmission gear 322 also rotates on itself (clockwise as seen in the figure), so that the sliding guide column 3241 at the other end of the transmission rod 324 slides upward along the sliding guide groove 32511, so as to drive the transmission shaft 325 to rotate inwardly around the second axis (clockwise as seen in the figure). When the transmission shaft 325 rotates around the second axis, it drives the vehicle door 300 to rotate around the second axis together, so as to realize the inward closing of the vehicle door 300, thereby realizing the oblique downward closing of the vehicle door 300.

[0069] In some embodiments, the transmission shaft 325 includes a transmission shaft section 3251 and a connecting shaft section 3252 distributed along the axial direction, a sliding guide groove 32511 is provided on the transmission shaft section 3251, and the connecting shaft section 3252 is fixedly connected to the second mounting member 2, so that the connecting shaft section 3252 and the second mounting member 2 are connected as an integral structure, so that when the transmission shaft 325 rotates around the second axis, it can drive the second mounting member 2 to rotate around the second axis, and the connecting shaft section 3252 is rotatably connected to the transmission arm 321, so that the transmission shaft 325 can rotate around the second axis relative to the transmission arm 321, so that the second mounting member 2 can rotate around the second axis relative to the transmission arm 321.

[0070] Therefore, by setting up a transmission shaft section 3251 and a connecting shaft section 3252 distributed along the axial direction, the transmission shaft 325 can be fixedly connected to the second mounting member 2 and can also be rotatably connected to the transmission arm 321, thereby realizing the rotational movement of the transmission shaft 325 relative to the transmission arm 321, and when the transmission shaft 325 rotates, it can drive the second mounting member 2 to rotate together, thereby improving the structural compactness of the vehicle door hinge assembly 100 and reducing the use of other components.

[0071] Specifically, if Figure 3 As shown, the transmission shaft 325 includes a transmission shaft section 3251 and a connecting shaft section 3252 distributed along the axial direction. Figure 3 As shown in the upper and lower directions, the transmission shaft section 3251 is located at the upper part of the transmission shaft 325, and the connecting shaft section 3252 is located at the lower part of the transmission shaft 325. The transmission shaft section 3251 is provided with an inclined sliding guide groove 32511, and the connecting shaft section 3252 can be fixedly connected to the second mounting part 2 by bolt connection, screw connection, keyway connection, clamping, etc., which is flexible and optional.

[0072] As well as Figure 6 As shown, a connecting hole 46 can be provided on the transmission arm 321, and the connecting hole 46 is adapted to the connecting shaft section 3252 of the transmission shaft 325, so that the connecting shaft section 3252 can be passed through the connecting hole 46 and can be flexibly rotated in the connecting hole 46, thereby realizing the rotational connection of the connecting shaft section 3252 to the transmission arm 321.

[0073] In some embodiments, the transmission arm 321 is provided with a rotating connection block 3211 , the rotating connection block 3211 includes at least two first connection parts 32111 , and the second mounting member 2 is provided with at least two second connection parts 21 .

[0074] That is to say, the rotating connecting block 3211 can include two, three or even more first connecting parts 32111, and the second mounting member 2 can be provided with two, three or even more second connecting parts 21. The first connecting part 32111 is used to connect the transmission shaft 325 to realize the rotating connection between the transmission arm 321 and the transmission shaft 325, and the second connecting part 21 is also used to connect the transmission shaft 325 to realize the fixed connection between the transmission shaft 325 and the second mounting member 2.

[0075] Furthermore, the second connecting portion 21 is fixedly connected to the transmission shaft 325, and the connection can be fixed by bolting, screwing, keyway connection, clamping, welding, integral molding, etc., which is stable, reliable, and flexible. A connecting hole 46 can be provided on the first connecting portion 32111, and the connecting hole 46 is adapted to the shape and size of the transmission shaft 325, so that the transmission shaft 325 can be inserted into the connecting hole 46 and rotate in the connecting hole 46, thereby enabling the transmission shaft 325 to be rotated through the first connecting portion 32111 and achieving relative rotation between the transmission arm 321 and the transmission shaft 325.

[0076] Among them, at least two first connecting parts 32111 and at least two second connecting parts 21 are staggered along the axial direction of the transmission shaft 325. In this way, the connection between the second mounting part 2 and the transmission shaft 325 can be made more stable and reliable, and the transmission shaft 325 can more smoothly drive the second mounting part 2 to rotate together to prevent the second mounting part 2 from offsetting or shaking during movement. The connection between the transmission arm 321 and the transmission shaft 325 can be made more stable and reliable, and the transmission arm 321 can more stably drive the transmission shaft 325 to rotate. In this way, the axial dimension of the transmission shaft 325 can also be reduced, thereby further reducing the space occupied by the door hinge assembly 100.

[0077] Specifically, if Figure 3 As shown, the transmission arm 321 is provided with a rotating connecting block 3211, and the rotating connecting block 3211 includes three first connecting parts 32111, and the three first connecting parts 32111 are distributed along the up and down directions, that is, the axial direction of the transmission shaft 325. The second mounting member 2 is provided with two second connecting parts 21, and the two second connecting parts 21 are distributed along the up and down directions, that is, the axial direction of the transmission shaft 325. Each first connecting part 32111 is provided with a connecting hole 46 that passes through in the thickness direction. The transmission shaft 325 can be sequentially passed through the three connecting holes 46 to realize the rotating connection between the transmission arm 321 and the transmission shaft 325, and the two second connecting parts 21 can be respectively located between adjacent first connecting parts 32111 to be fixedly connected to the transmission shaft 325, so that the three first connecting parts 32111 and the two second connecting parts 21 are staggered along the axial direction of the transmission shaft 325.

[0078] In some embodiments, the transmission gear 322 is rotatably mounted on the transmission arm 321 about a third axis, the third axis is parallel to and spaced apart from the first axis, and the third axis is located between the first axis and the second axis.

[0079] That is, the transmission gear 322 is transmitted between the mating gear 323 and the transmission shaft 325, and the transmission gear 322 also rotates in the vertical plane. Figure 2-Figure 4 As shown, the transmission gear 322 rotates around the second rotating shaft 45, that is, the axis of the second rotating shaft 45 is the third axis, and the transmission gear 322 is rotatably mounted on the transmission arm 321 through the second rotating shaft 45, and the second rotating shaft 45 is parallel to and spaced apart from the first rotating shaft 44, that is, the third axis is spaced apart from the first axis to ensure that the mating gear 323 is meshed with the transmission gear 322, and the transmission gear 322 can rotate under the action of the mating gear 323, and the second rotating shaft 45 is located between the first rotating shaft 44 and the transmission shaft 325, that is, the third axis is located between the first axis and the second axis, which ensures the compactness of the transmission structure, improves the transmission efficiency, and makes the transmission more stable.

[0080] In some embodiments, the first mounting member 1 is provided with a limit block 11 , and the transmission arm 321 is limited below the limit block 11 when it rotates to the maximum position relative to the first mounting member 1 .

[0081] Specifically, the limit block 11 can be set on the upper side or the lower side of the transmission arm 321, or the limit blocks 11 can be set on both the upper side and the lower side. Figure 2 As shown in the upper and lower directions, when the transmission arm 321 rotates upward to the maximum position relative to the first mounting member 1, the transmission arm 321 can be limited and pressed against the limit block 11 to limit the transmission arm 321 from rotating upward by too large an angle, causing the door 300 to open at too large an angle; and when the transmission arm 321 rotates downward to the maximum position relative to the first mounting member 1, the transmission arm 321 can be limited and pressed against the limit block 11 to limit the transmission arm 321 from continuing to rotate downward by too large an angle under the action of the gravity and inertia of the door 300, causing the door 300 to hit the vehicle body 200.

[0082] In some embodiments, the transmission arm 321 includes a rotating disk portion 3212 and a connecting limit portion 3213. The rotating disk portion 3212 is rotatably connected to the first mounting member 1, and the connecting limit portion 3213 is connected to the outer side of the rotating disk portion 3212. The driving member 31 and the second mounting member 2 are respectively connected to the connecting limit portion 3213, and the connecting limit portion 3213 is suitable for limiting and pressing against the limit block 11.

[0083] Specifically, if Figure 6As shown, the transmission arm 321 includes a rotating disk portion 3212 and a connecting and limiting portion 3213. The connecting and limiting portion 3213 is mainly used to connect to the transmission shaft 325, and the rotating disk portion 3212 is mainly used to realize power transmission. Among them, the rotating disk portion 3212 is connected to the first mounting member 1 and can rotate relative to the first mounting member 1. The connecting and limiting portion 3213 is connected to the outer side of the rotating disk portion 3212. Figure 6 The connection limit portion 3213 shown in the figure is connected to the lower side of the rotating disk portion 3212, the driving member 31 is connected to the bottom of the connection limit portion 3213, and the second mounting member 2 is connected to the side of the connection limit portion 3213, so that the connection between the transmission arm 321 and the driving member 31 and the second mounting member 2 is realized through the connection limit portion 3213, thereby further improving the structural compactness of the vehicle door hinge assembly 100 without setting other connecting components.

[0084] In practice, when the transmission arm 321 rotates downward to the initial position around the first axis, it may continue to rotate downward due to the gravity and inertia of the vehicle door 300, causing the vehicle door 300 to collide with the vehicle body 200, causing damage to the vehicle door 300 and the vehicle body 200. By setting the limit block 11 on the side of the connecting limit portion 3213, when the transmission arm 321 rotates downward to the initial position around the first axis, the connecting limit portion 3213 can be pressed against the limit block 11 to limit the transmission arm 321 from continuing to rotate downward, thereby preventing the vehicle door 300 from colliding with the vehicle body 200 and effectively protecting the vehicle door 300 and the vehicle body 200.

[0085] In actual design, the limit block 11 may include a metal core and external rubber, the external rubber is wrapped around the outside of the metal core, the metal core is used to support the limit block 11, and the external rubber is used for buffering and limiting to prevent the connection limit part 3213 from pressing against the limit block 11, causing abnormal noise and damage to the connection limit part 3213.

[0086] In some embodiments, the driving member 31 is connected to an end of the connection limit portion 3213 away from the rotating disk portion 3212 .

[0087] Specifically, if Figures 1-4 As shown, the driving member 31 is connected to the bottom end of the connection limit portion 3213, that is, the end of the connection limit portion 3213 away from the rotating disk portion 3212. In this way, the driving member 31 can drive the entire transmission arm 321 to move stably.

[0088] In other embodiments, the limiting block 11 and the second mounting member 2 are respectively located on both sides of the connection limiting portion 3213 .

[0089] Specifically, if Figures 1-4 As shown, Figures 1-4The front and rear directions shown in the figure are the front and rear directions of the vehicle, the limit block 11 is located on the front side of the connection limit portion 3213, and the second mounting member 2 is located on the rear side of the connection limit portion 3213, so that the limit block 11 and the second mounting member 2 are respectively located on both sides of the connection limit portion 3213, thereby avoiding the limit block 11 affecting the movement of the second mounting member 2, and at the same time, it can effectively ensure that the transmission arm 321 is limited.

[0090] In some embodiments, the driving member 31 is configured to drive a telescopic rod, which is configured to be retractable. One end of the driving telescopic rod is rotatably connected to the first mounting member 1 , and the other end of the driving telescopic rod is rotatably connected to the transmission arm 321 .

[0091] Specifically, when the telescopic rod is driven to extend, the transmission arm 321 can be pushed to rotate upward around the first axis. At the same time, the transmission arm 321 drives the transmission shaft 325 and the second mounting member 2 to rotate upward around the first axis. When the second mounting member 2 rotates upward, it can drive the car door 300 to rotate upward around the first axis, thereby realizing the upward opening of the car door 300. When the telescopic rod is driven to shorten, the transmission arm 321 can be pulled to rotate downward around the first axis. At the same time, the transmission arm 321 drives the transmission shaft 325 and the second mounting member 2 to rotate downward around the first axis. When the second mounting member 2 rotates upward, it can drive the car door 300 to rotate downward around the first axis, thereby realizing the downward closing of the car door 300.

[0092] In actual design, Figure 2 As shown, a first ball stud 12 can be provided on the first mounting member 1, the first ball stud 12 can be riveted to the first mounting member 1, and the first ball stud 12 is connected to one end of the driving telescopic rod by a ball hinge to realize the rotational connection between one end of the driving telescopic rod and the first mounting member 1, and a second ball stud 3214 can be provided on the transmission arm 321, the second ball stud 3214 can be riveted to the transmission arm 321, and the second ball stud 3214 is connected to the other end of the driving telescopic rod by a ball hinge to realize the rotational connection between the other end of the driving telescopic rod and the transmission arm 321, so that one end of the driving telescopic rod can rotate in any direction relative to the first mounting member 1, and the other end of the driving telescopic rod can rotate in any direction relative to the transmission arm 321, thereby enhancing flexibility and adaptability.

[0093] It should be noted that the driving telescopic rod can be a telescopic rod of an electric strut, which drives the telescopic rod to extend or retract along the axial direction of the strut housing. The electric strut may further include a motor, a screw, etc. to achieve the driving telescopic rod extension or retraction. It is understood that by controlling the extension of the driving telescopic rod, the rotation angle of the vehicle door 300 about the first axis can be controlled, thereby achieving flexible adjustment of the upward opening angle of the vehicle door 300.

[0094] In some embodiments, the rotation angle of the transmission arm 321 relative to the first mounting member 1 is A1, and satisfies: 65°≤A1≤95°.

[0095] That is to say, the rotation angle A1 of the transmission arm 321 relative to the first mounting member 1 can be 65°, 70°, 75°, 80°, 85°, 90°, 95° or other angles within the range of 65° to 95°, to prevent the upward opening angle from being too small, which prevents the occupants from entering and exiting normally, and to prevent the opening angle from being too large, which causes the vehicle body 200 to be deformed, the driving mechanism 3 to be overloaded, and the door 300 to hit the top obstacle, causing damage to the door 300, etc.

[0096] Therefore, by setting the rotation angle A1 of the transmission arm 321 relative to the first mounting member 1 within a reasonable range of 65° to 95°, the normal entry and exit of passengers is ensured, the driving mechanism 3, the vehicle door 300 and the vehicle body 200 are protected, the service life of the door hinge assembly 100 is extended, the safety of the vehicle is improved, and the risk of accidents is reduced.

[0097] In other embodiments, the rotation angle of the second mounting member 2 relative to the transmission arm 321 is A2, and satisfies: 0°≤A2≤20°.

[0098] That is to say, the rotation angle A2 of the second mounting member 2 relative to the transmission arm 321 can be set to 0°, 5°, 10°, 15°, 20° or other angles within this range to prevent the outward opening angle from being too small, making it difficult for passengers to get in and out, and to prevent the outward opening angle from being too large, causing the door 300 to occupy too much lateral space, making it easy to be hit by other vehicles or pedestrians when parking in a narrow passage or sideways.

[0099] Therefore, by setting the rotation angle A2 of the second mounting member 2 relative to the transmission arm 321 within a reasonable range of 0° to 20°, normal entry and exit of passengers is ensured, the safety of the vehicle is improved, the risk of accidents is reduced, and the user experience is enhanced.

[0100] The present invention also provides a vehicle.

[0101] The vehicle according to the embodiment of the present invention includes a vehicle body 200 , a vehicle door 300 and the door hinge assembly 100 according to any one of the above embodiments. The first mounting member 1 is connected to the vehicle body 200 , and the second mounting member 2 is connected to the vehicle door 300 .

[0102] Thus, by the second mounting member 2 moving in two directions relative to the first mounting member 1 , the vehicle door 300 can be opened obliquely upward relative to the vehicle body 200 , which is flexible and convenient.

[0103] Among them, by setting a driving mechanism 3 including a driving member 31 and a transmission assembly 32, the driving member 31 drives the second mounting member 2 to move in two directions relative to the first mounting member 1 through the transmission assembly 32 to realize the opening and closing of the vehicle door 300. It has a simple structure, is easy to install and disassemble, is highly compact, occupies a small space, is easy to arrange and install on the vehicle body 200, and the transmission assembly 32 has high transmission efficiency and good transmission stability, so that the opening and closing process of the vehicle door 300 is more stable and reliable, and the user experience is better.

[0104] In actual design, the first mounting member 1 can be connected to the side wall of the vehicle body 200 .
