Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0035] To address the technical problem of interference between the front and rear doors of automobiles with pillarless suicide door designs in the prior art, one embodiment of this application provides a hinge device. The hinge device includes a first mounting member for connection to a vehicle door. The hinge device also includes a first drive assembly, which is tractively connected to the first mounting member. The hinge device further includes a rotating arm, which is tractively connected to the first drive assembly. The hinge device also includes a second mounting member for connection to the vehicle body, and the second mounting member is rotatably connected to the rotating arm. The first drive assembly is configured to drive the first mounting member to rotate relative to the rotating arm, thereby causing the first mounting member to open or close the door relative to the vehicle body. This will be described in detail below.

[0036] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of an embodiment of the car door and the car body that are rotatably connected by a hinge device according to this application. Figure 2 This is a schematic diagram of an embodiment of the motion envelope of the front and rear doors of the vehicle of this application.

[0037] In one embodiment, the vehicle includes a body 10 and doors 20, with doors 20 rotatably connected to the body 10 via hinges 30. The vehicle may employ a pillarless, double-door design, specifically, doors 20 include a front door 21 and a rear door 22, located on the same side of the body 10. The side of the front door 21 away from the rear door 22 is rotatably connected to the body 10, and the side of the rear door 22 away from the front door 21 is rotatably connected to the body 10; that is, the front door 21 and rear door 22 are double-door structures. The front door 21 and / or the rear door 22 are rotatably connected to the body 10 via hinges 30.

[0038] The hinge device 30 of the present application embodiment will be described below.

[0039] In one embodiment, the hinge device 30 includes a first mounting member 31 for connection to a vehicle door 20. The hinge device 30 also includes a first drive assembly 34, which is throttle-connected to the first mounting member 31. The hinge device 30 further includes a rotating arm 32, which is throttle-connected to the first drive assembly 34. The hinge device 30 also includes a second mounting member 33 for connection to the vehicle body 10, and the second mounting member 33 is rotatably connected to the rotating arm 32.

[0040] The rotating arm 32 can be rotatably connected to the first mounting member 31 and the second mounting member 33 respectively, or one end of the rotating arm 32 can be rotatably connected to the first mounting member 31 via the first drive assembly 34, and the other end can be rotatably connected to the second mounting member 33. This application uses the example of the rotating arm 32 being rotatably connected to the first mounting member 31 and the second mounting member 33 respectively for illustrative purposes only and is not intended to limit the scope of the application.

[0041] In this embodiment, the hinge device 30 employs a dual-axis rotation design. The connection between the rotating arm 32 and the first mounting member 31 has a first axis of rotation O1, allowing relative rotation between the rotating arm 32 and the first mounting member 31 around the first axis of rotation O1. The connection between the rotating arm 32 and the second mounting member 33 has a second axis of rotation O2, allowing relative rotation between the rotating arm 32 and the second mounting member 33 around the second axis of rotation O2. In this way, the hinge device 30, through the cooperation of the first axis of rotation O1 and the second axis of rotation O2, constrains the movement trajectory of the door 20, enabling the door 20 to achieve specific composite movements during opening and closing, thus reducing the risk of interference between the door 20 and other structures during opening and closing. Especially for vehicles with a pillarless, double-door design, the hinge device 30 can reduce the risk of interference between doors 20 (such as the aforementioned front door 21 and rear door 22), greatly improving adaptability to vehicle side profiles.

[0042] For example, such as Figures 3 to 5 As shown, the movement trajectory of the door 20 in this embodiment includes a closed position S1, a transition position S2, and an open position S3. In the open position S3, the angle at which the door 20 opens relative to the vehicle body 10 is greater than the angle at which the door 20 opens relative to the vehicle body 10 in the closed position S1. During the opening process, the door 20 moves from the closed position S1 through the transition position S2 to the open position S3, and during the closing process, the door 20 moves from the open position S3 through the transition position S2 back to the closed position S1. Taking the opening process of the door 20 as an example, during the movement of the door 20 from the closed position S1 to the transition position S2, the rotating arm 32 rotates relative to the first mounting member 31, and also rotates relative to the second mounting member 33. During the movement of the door 20 from the closed position S1 to the transition position S2, the relative rotation between the rotating arm 32 and the first mounting member 31 stops, while the relative rotation between the rotating arm 32 and the second mounting member 33 continues, causing the door 20 to move from the transition position S2 to the open position S3, thus completing the opening process of the door 20.

[0043] Figure 6The motion envelopes of the front door 41 and the rear door 42 of a vehicle with a pillarless double-door design in the prior art are shown. It can be seen that the motion envelopes of the front door 41 and the rear door 42 overlap, which makes it easy for the front door 41 and the rear door 42 to interfere during the opening and closing process. Figure 2 The motion envelopes of the front door 21 and the rear door 22 in this embodiment are illustrated by way of example. It can be seen that the motion envelopes of the front door 21 and the rear door 22 do not overlap. The hinge device 30 in this embodiment avoids the problem of interference between the front door 21 and the rear door 22 during opening and closing. The hinge device 30 in this embodiment can adapt to the needs of various vehicle models for B-pillarless suicide door designs.

[0044] Please refer to the following: Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the structure of an embodiment of the first driving component of this application. Figure 8 yes Figure 7 The diagram shows the exploded structure of the first driving component.

[0045] In one embodiment, the hinge device 30 further includes a first drive assembly 34, which is tractively connected to the first mounting member 31 and the rotating arm 32. The first drive assembly 34 is configured to drive the first mounting member 31 to rotate relative to the rotating arm 32, thereby causing the first mounting member 31 to open or close the door 20 relative to the vehicle body 10. In this way, the hinge device 30 of this embodiment can automatically open and close the door 20 through the first drive assembly 34.

[0046] Specifically, the first drive assembly 34 includes a first power component 341, a first transmission gear 342, and a first transmission sector gear 343. The first power component 341 may be a power element such as a motor. The first transmission gear 342 is connected to the first power component 341, and both the first power component 341 and the first transmission gear 342 are located on one of the first mounting member 31 and the rotating arm 32. The first transmission sector gear 343 meshes with the first transmission gear 342, and is located on the other of the first mounting member 31 and the rotating arm 32. The first power component 341 drives the first transmission sector gear 343 to rotate via the first transmission gear 342, thereby driving the first mounting member 31 to rotate relative to the rotating arm 32. Figure 7 An exemplary illustration shows that the first power component 341 and the first transmission gear 342 are both located on the rotating arm 32, and the first transmission gear sector 343 is located on the first mounting component 31.

[0047] The hinge device 30 also includes a first rotating shaft 35. The first mounting member 31 and the rotating arm 32 are rotatably connected via the first rotating shaft 35, meaning that the first mounting member 31 and the rotating arm 32 can rotate relative to each other around the central axis of the first rotating shaft 35. The central axis of the first rotating shaft 35 coincides with the rotation axis of the first transmission gear sector 343, thus ensuring that the rotation of the first transmission gear sector 343 does not interfere with the relative rotation between the first mounting member 31 and the rotating arm 32.

[0048] For example, along the axial direction of the first rotating shaft 35, the first power component 341, the first transmission gear 342, and the first transmission gear sector 343 are all located on one side of the first rotating shaft 35. In this way, this embodiment enables the transmission design between the first power component 341, the first transmission gear 342, and the first transmission gear sector 343, thereby achieving a transmission connection between the first drive assembly 34 and the first mounting member 31 and the rotating arm 32, respectively, allowing the hinge device 30 to automatically open and close the door 20 via the first drive assembly 34. The first drive assembly 34 also includes a first dust cover 344, which covers one side of the first mounting member 31 and the rotating arm 32, and the interior of the first dust cover 344 has a first dustproof cavity 345. Because the first power component 341, the first transmission gear 342, and the first transmission gear sector 343 are all located on one side of the first rotating shaft 35 along its axial direction, they can all be accommodated within the first dustproof chamber 345. The first dustproof cover 344 can prevent external impurities from entering the first drive assembly 34, which helps ensure the stability of the first drive assembly 34.

[0049] Please refer to the following: Figure 9 , Figure 9 This is a schematic diagram of another embodiment of the door and body of the vehicle being rotatably connected by a hinge device.

[0050] In an alternative embodiment, the first drive assembly 34 includes a first electrically operated telescopic rod 346, the two ends of which are respectively connected to the first mounting member 31 and the rotating arm 32. The first electrically operated telescopic rod 346 is configured to drive the first mounting member 31 to rotate relative to the rotating arm 32, thereby causing the first mounting member 31 to open or close the door 20 relative to the vehicle body 10. In this way, the hinge device 30 in this embodiment can automatically open and close the door 20 through the first electrically operated telescopic rod 346.

[0051] Please refer to the following: Figure 10 , Figure 10 This is a structural schematic diagram of an embodiment of the vehicle body of this application.

[0052] In one embodiment, the first mounting member 31 and the rotating arm 32 are detachably connected. The vehicle body 10 also has a clearance hole 11. The second mounting member 33 is used to be installed inside the vehicle body 10, the clearance hole 11 communicates with the interior of the vehicle body 10, and the rotating arm 32 can be movably inserted through the clearance hole 11, so that the rotating arm 32 can be rotatably connected to the first mounting member 31 and the second mounting member 33 respectively.

[0053] In this embodiment, the vehicle body 10 has a clearance hole 11 that connects to the interior of the vehicle body 10. The rotating arm 32 is movably inserted through the clearance hole 11, allowing the rotating arm 32 to be connected to both the first mounting member 31 and the second mounting member 33. The first mounting member 31 and the rotating arm 32 are detachably connected, facilitating the installation of the hinge device 30. Furthermore, the first mounting member 31 does not need to pass through the clearance hole 11, allowing for a smaller opening area in the clearance hole 11, which helps ensure the structural strength of the vehicle body 10. If the first mounting member 31 and the rotating arm 32 were not detachable, the entire first mounting member 31 would need to pass through the clearance hole 11 to be installed on the door 20. This would require a larger opening area in the clearance hole 11, potentially weakening the structural strength of the vehicle body 10 to some extent.

[0054] It should be noted that, taking the rear door 22 of the vehicle as an example, the second mounting member 33 is installed within the C-pillar structure 12 of the vehicle body 10. In this embodiment, at least a portion of the second mounting member 33 and the rotating arm 32 are located within the C-pillar structure 12 of the vehicle body 10. This not only enhances the structural strength of the vehicle body 10 and improves the overall structural safety performance, but also optimizes the structural layout of the hinge device 30, which is beneficial for improving space utilization. Furthermore, the hinge device 30 has a compact structure, which facilitates the installation design of the hinge device 30 embedded in the C-pillar structure 12, while saving space in the vehicle body 10. In addition, the hinge device 30 is manufactured using a forging process, which helps to ensure the structural stability and safety of the hinge device 30 and meets stringent automotive industry standards.

[0055] In the example described above, the first drive assembly 34 includes a first power component 341, a first transmission gear 342, and a first transmission gear sector 343. The first transmission gear 342 and the first transmission gear sector 343 are detachably connected, allowing the first drive assembly 34 to adapt to the detachable design between the first mounting member 31 and the rotating arm 32. The first mounting member 31 and the rotating arm 32 are detachably connected via a first rotating shaft 35. After the first mounting member 31 and the rotating arm 32 are detached, the first transmission gear 342 and the first transmission gear sector 343 are also correspondingly detached. The first power component 341 and the first transmission gear 342 can be disposed on the rotating arm 32. The first power component 341 and the first transmission gear 342 can be disassembled and assembled together with the rotating arm 32, or the first power component 341 and the first transmission gear 342 can also be detachably disposed from the rotating arm 32, further facilitating the installation of the hinge device 30; the first transmission gear sector 343 can be disposed on the first mounting component 31. The first transmission gear sector 343 can be disassembled and assembled together with the first mounting component 31, or the first transmission gear sector 343 can also be detachably disposed from the first mounting component 31, further facilitating the installation of the hinge device 30.

[0056] Furthermore, the first transmission gear sector 343 is provided with a first retraction hole 3431. The first retraction hole 3431 extends through the first transmission gear sector 343 in the axial direction of the first rotating shaft 35, and is positioned opposite to the first rotating shaft 35. When it is necessary to disassemble the first mounting member 31 and the rotating arm 32, the first rotating shaft 35 can be pushed out from between the first mounting member 31 and the rotating arm 32 through the first retraction hole 3431, thus allowing the first mounting member 31 and the rotating arm 32 to be disassembled.

[0057] In the example described above, the first drive assembly 34 includes a first electric telescopic rod 346. Both ends of the first electric telescopic rod 346 are detachably connected to the first mounting member 31 and the rotating arm 32, respectively, allowing the first drive assembly 34 to adapt to the detachable design between the first mounting member 31 and the rotating arm 32. After the first mounting member 31 and the rotating arm 32 are detached, both ends of the first electric telescopic rod 346 are also detached from the first mounting member 31 and the rotating arm 32, respectively.

[0058] Please refer to the following: Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the structure of an embodiment of the second driving component of this application. Figure 12 yes Figure 11 The diagram shows the exploded structure of the second drive component.

[0059] In one embodiment, the hinge device 30 further includes a second drive assembly 36, which is pulsatorically connected to the rotating arm 32 and the second mounting member 33, respectively. The second drive assembly 36 is configured to drive the rotating arm 32 to rotate relative to the second mounting member 33. The first drive assembly 34 and the second drive assembly 36 cooperate to drive the door 20 to open or close relative to the vehicle body 10, thereby automating the opening and closing of the door 20.

[0060] Taking the opening process of the car door 20 as an example, during the process of the car door 20 moving from the closed position S1 to the transition position S2, the first drive assembly 34 drives the rotating arm 32 to rotate relative to the first mounting member 31, and the second drive assembly 36 drives the rotating arm 32 to rotate relative to the second mounting member 33. During the process of the car door 20 moving from the closed position S1 to the transition position S2, the rotating arm 32 and the first mounting member 31 stop rotating relative to each other, while the second drive assembly 36 continues to drive the rotating arm 32 and the second mounting member 33 to continue rotating relative to each other, so that the car door 20 moves from the transition position S2 to the open position S3, thus completing the opening process of the car door 20.

[0061] In one embodiment, the second drive assembly 36 includes a second power component 361, a second transmission gear 362, and a second transmission sector gear 363. The second power component 361 may be a power element such as a motor. The second transmission gear 362 is connected to the second power component 361, and both the second power component 361 and the second transmission gear 362 are located on one of the second mounting member 33 and the rotating arm 32. The second transmission sector gear 363 meshes with the second transmission gear 362, and is located on the other of the second mounting member 33 and the rotating arm 32. The second power component 361 drives the second transmission sector gear 363 to rotate via the second transmission gear 362, thereby driving the second mounting member 33 to rotate relative to the rotating arm 32. Figure 11 An exemplary embodiment shows that the second power component 361 and the second transmission gear 362 are both located on the rotating arm 32, and the second transmission gear sector 363 is located on the second mounting component 33.

[0062] The hinge device 30 also includes a second rotating shaft 37. The second mounting member 33 and the rotating arm 32 are rotatably connected via the second rotating shaft 37, meaning that the second mounting member 33 and the rotating arm 32 can rotate relative to each other around the central axis of the second rotating shaft 37. The central axis of the second rotating shaft 37 coincides with the rotation axis of the second transmission gear sector 363, thus ensuring that the rotation of the second transmission gear sector 363 does not interfere with the relative rotation between the second mounting member 33 and the rotating arm 32.

[0063] For example, along the axial direction of the second rotating shaft 37, the second power component 361, the second transmission gear 362, and the second transmission gear sector 363 are all located on one side of the second rotating shaft 37. In this way, this embodiment enables the transmission design between the second power component 361, the second transmission gear 362, and the second transmission gear sector 363, thereby achieving a transmission connection between the second drive assembly 36 and the rotating arm 32 and the second mounting member 33, respectively, allowing the hinge device 30 to automatically open and close the door 20. The second drive assembly 36 also includes a second dust cover 365, which covers one side of the second mounting member 33 and the rotating arm 32, and the interior of the second dust cover 365 has a second dustproof cavity 366. Because the second power component 361, the second transmission gear 362, and the second transmission gear sector 363 are all located on one side of the second shaft 37 along its axial direction, they can all be accommodated within the second dustproof chamber 366. The second dustproof cover 365 can prevent external impurities from entering the second drive assembly 36, which helps ensure the stability of the second drive assembly 36.

[0064] In an alternative embodiment, the second drive assembly 36 includes a second electrically operated telescopic rod 364, with both ends of the second electrically operated telescopic rod 364 being drively connected to the second mounting member 33 and the rotating arm 32, respectively. The second electrically operated telescopic rod 364 is configured to drive the second mounting member 33 to rotate relative to the rotating arm 32, thereby causing the second mounting member 33 to open or close the door 20 relative to the vehicle body 10. In this way, the hinge device 30 in this embodiment can automatically open and close the door 20 via the second electrically operated telescopic rod 364.

[0065] In one embodiment, the second mounting member 33 is detachably connected to the rotating arm 32, which facilitates the installation of the hinge device 30. Correspondingly, the rotating arm 32, the second mounting member 33, and the second drive assembly 36 are detachably connected, so that the second drive assembly 36 can be adapted to the detachable design between the second mounting member 33 and the rotating arm 32.

[0066] In the example of the second drive assembly 36 including a second power component 361, a second transmission gear 362, and a second transmission gear sector 363, the second transmission gear 362 and the second transmission gear sector 363 are detachably connected, allowing the second drive assembly 36 to adapt to the detachable design between the second mounting member 33 and the rotating arm 32. The second mounting member 33 and the rotating arm 32 are detachably connected via a second rotating shaft 37. After the second mounting member 33 is detached from the rotating arm 32, the second transmission gear 362 and the second transmission gear sector 363 are also correspondingly detached. The second power component 361 and the second transmission gear 362 can be disposed on the rotating arm 32. The second power component 361 and the second transmission gear 362 can be disassembled and assembled together with the rotating arm 32, or the second power component 361 and the second transmission gear 362 can also be detachably disposed from the rotating arm 32, further facilitating the installation of the hinge device 30; the second transmission gear sector 363 can be disposed on the second mounting component 33. The second transmission gear sector 363 can be disassembled and assembled together with the second mounting component 33, or the second transmission gear sector 363 can also be detachably disposed from the second mounting component 33, further facilitating the installation of the hinge device 30.

[0067] Furthermore, the second transmission gear sector 363 is provided with a second retraction hole 3631. The second retraction hole 3631 extends through the second transmission gear sector 363 in the axial direction of the second rotating shaft 37, and is positioned opposite to the second rotating shaft 37. When it is necessary to disassemble the second mounting member 33 from the rotating arm 32, the second rotating shaft 37 can be pushed out from between the second mounting member 33 and the rotating arm 32 through the second retraction hole 3631, thus allowing the second mounting member 33 and the rotating arm 32 to be disassembled.

[0068] In the example described above, the second drive assembly 36 includes a second electrically operated telescopic rod 364. Both ends of the second electrically operated telescopic rod 364 are detachably connected to the second mounting member 33 and the rotating arm 32, respectively, allowing the second drive assembly 36 to adapt to the detachable design between the second mounting member 33 and the rotating arm 32. After the second mounting member 33 is detached from the rotating arm 32, both ends of the second electrically operated telescopic rod 364 are also detached from the second mounting member 33 and the rotating arm 32, respectively.

[0069] The technical solutions provided in the embodiments of this application will be described below with reference to specific examples.

[0070] Example 1:

[0071] The hinge device 30 includes a first mounting member 31 for connection to a vehicle door 20. The hinge device 30 also includes a rotating arm 32 rotatably connected to the first mounting member 31. The hinge device 30 further includes a second mounting member 33 for connection to the vehicle body 10, and the second mounting member 33 is rotatably connected to the rotating arm 32. The hinge device 30 also includes a first drive assembly 34, which is drively connected to both the first mounting member 31 and the rotating arm 32. The first drive assembly 34 is configured to drive the first mounting member 31 to rotate relative to the rotating arm 32, thereby causing the first mounting member 31 to open or close the door 20 relative to the vehicle body 10.

[0072] The rotating arm 32 is rotatably connected to both the first mounting member 31 and the second mounting member 33, meaning the hinge device 30 employs a dual-rotation-axis design, which reduces the risk of interference between the door 20 and other structures during opening and closing. This is particularly beneficial for vehicles with pillarless, double-door designs, as the hinge device 30 minimizes the risk of interference between the doors 20. Furthermore, the hinge device 30 includes a first drive assembly 34, which drives the first mounting member 31 to rotate relative to the rotating arm 32. This causes the first mounting member 31 to open or close the door 20 relative to the vehicle body 10, meaning the hinge device 30 can automatically open and close the door 20 via the first drive assembly 34.

[0073] Example 2:

[0074] The first drive assembly 34 includes a first power component 341, a first transmission gear 342, and a first transmission sector gear 343. The first power component 341 may be a power element such as a motor. The first transmission gear 342 is connected to the first power component 341, and both the first power component 341 and the first transmission gear 342 are located on one of the first mounting member 31 and the rotating arm 32. The first transmission sector gear 343 meshes with the first transmission gear 342, and is located on the other of the first mounting member 31 and the rotating arm 32. The first power component 341 drives the first transmission sector gear 343 to rotate via the first transmission gear 342, thereby driving the first mounting member 31 to rotate relative to the rotating arm 32.

[0075] The hinge device 30 also includes a first rotating shaft 35. The first mounting member 31 and the rotating arm 32 are rotatably connected via the first rotating shaft 35, meaning that the first mounting member 31 and the rotating arm 32 can rotate relative to each other around the central axis of the first rotating shaft 35. The central axis of the first rotating shaft 35 coincides with the rotation axis of the first transmission gear sector 343, thus ensuring that the rotation of the first transmission gear sector 343 does not interfere with the relative rotation between the first mounting member 31 and the rotating arm 32.

[0076] Example 3:

[0077] The first mounting member 31 and the rotating arm 32 are detachably connected. The vehicle body 10 also has a clearance hole 11. The second mounting member 33 is installed inside the vehicle body 10. The clearance hole 11 connects to the interior of the vehicle body 10, and the rotating arm 32 can be movably inserted through the clearance hole 11, allowing the rotating arm 32 to be rotatably connected to both the first mounting member 31 and the second mounting member 33. The vehicle body 10 has a clearance hole 11 connecting to the interior of the vehicle body 10, and the rotating arm 32 can be movably inserted through the clearance hole 11, allowing the rotating arm 32 to be connected to both the first mounting member 31 and the second mounting member 33. In this embodiment, the detachable connection between the first mounting member 31 and the rotating arm 32 facilitates the installation of the hinge device 30 and eliminates the need for the first mounting member 31 to pass through the clearance hole 11, allowing for a smaller opening area in the clearance hole 11, thus helping to ensure the structural strength of the vehicle body 10. If the first mounting component 31 and the rotating arm 32 are not detachable, it means that the entire first mounting component 31 needs to pass through the clearance hole 11 to be installed on the door 20. This results in the clearance hole 11 needing to be designed with a larger opening area, which will weaken the structural strength of the body 10 to some extent.

[0078] Example 4:

[0079] The first transmission gear 342 and the first transmission gear sector 343 are detachably connected, allowing the first drive assembly 34 to adapt to the detachable design between the first mounting member 31 and the rotating arm 32. The first mounting member 31 and the rotating arm 32 are detachably connected via the first rotating shaft 35. After the first mounting member 31 and the rotating arm 32 are disassembled, the first transmission gear 342 and the first transmission gear sector 343 are also disassembled accordingly. The first power member 341 and the first transmission gear 342 can be mounted on the rotating arm 32 and can be disassembled and assembled together with the rotating arm 32, or the first power member 341 and the first transmission gear 342 can also be detachably mounted on the rotating arm 32, further facilitating the installation of the hinge device 30; the first transmission gear sector 343 can be mounted on the first mounting member 31 and can be disassembled and assembled together with the first mounting member 31, or the first transmission gear sector 343 can also be detachably mounted on the first mounting member 31, further facilitating the installation of the hinge device 30.
