[0035] In order to solve the technical problem in the prior art that the front and rear doors of a car with a double-door design without a B-pillar are prone to interference, an embodiment of the present application provides a hinge device. The hinge device includes a first mounting member, which is used to connect to the door of the vehicle. The hinge device also includes a first drive assembly, which is transmission-connected to the first mounting member. The hinge device also includes a rotating arm, which is transmission-connected to the first drive assembly. The hinge device also includes a second mounting member, which is used to connect to the body of the vehicle, and the second mounting member is rotationally connected to the rotating arm. Among them, the first drive assembly is configured to drive the first mounting member to rotate relative to the rotating arm, so that the first mounting member drives the door to open or close relative to the body. This is explained in detail below.

[0036] See also Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of an embodiment of the present invention in which a vehicle door and a vehicle body are rotatably connected via a hinge device. Figure 2 It is a schematic diagram of an embodiment of the motion envelope of the front door and the rear door of the vehicle of the present application.

[0037] In one embodiment, a vehicle includes a vehicle body 10 and a door 20, and the door 20 is rotatably connected to the vehicle body 10 via a hinge device 30. The vehicle may adopt a double-door design without a B-pillar, specifically, the door 20 includes a front door 21 and a rear door 22, the front door 21 and the rear door 22 are located on the same side of the vehicle body 10, the side of the front door 21 away from the rear door 22 is rotatably connected to the vehicle body 10, and the side of the rear door 22 away from the front door 21 is rotatably connected to the vehicle body 10, that is, the front door 21 and the rear door 22 are double-door structures. The front door 21 and / or the rear door 22 are rotatably connected to the vehicle body 10 via a hinge device 30.

[0038] The hinge device 30 according to the embodiment of the present application is described below.

[0039] In one embodiment, the hinge device 30 includes a first mounting member 31, and the first mounting member 31 is used to connect with the vehicle door 20. The hinge device 30 also includes a first drive assembly 34, and the first drive assembly 34 is transmission-connected to the first mounting member 31. The hinge device 30 also includes a rotating arm 32, and the rotating arm 32 is transmission-connected to the first drive assembly 34. The hinge device 30 also includes a second mounting member 33, which is used to connect with the vehicle body 10, and the second mounting member 33 is rotationally 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 through the first driving assembly 34, and the other end can be rotatably connected to the second mounting member 33. The embodiment of the present application is described by taking the rotating arm 32 being rotatably connected to the first mounting member 31 and the second mounting member 33 as an example, which is only for the purpose of discussion and is not intended to be limiting.

[0041] In the above manner, the hinge device 30 of this embodiment adopts a double rotation axis design. The connection between the rotating arm 32 and the first mounting member 31 has a first rotation axis O1, and the rotating arm 32 and the first mounting member 31 can rotate relative to each other around the first rotation axis O1. The connection between the rotating arm 32 and the second mounting member 33 has a second rotation axis O2, and the rotating arm 32 and the second mounting member 33 can rotate relative to each other around the second rotation axis O2. In this way, the hinge device 30 of this embodiment constrains the motion trajectory of the door 20 through the cooperation of the first rotation axis O1 and the second rotation axis O2, so that the door 20 can achieve a specific compound motion during the opening and closing process, and can reduce the risk of interference between the door 20 and other structures during the opening and closing process. In particular, for the case where the vehicle adopts a B-pillar-free double-door design, the hinge device 30 of this embodiment can reduce the risk of interference between the doors 20 (such as the front door 21 and the rear door 22 mentioned above), and greatly improve the adaptability to the side shape of the vehicle.

[0042] For example, Figures 3 to 5 As shown, the movement trajectory of the vehicle door 20 in this embodiment includes a closing position S1, a transition position S2, and an opening position S3. At the opening position S3, the angle at which the vehicle door 20 is opened relative to the vehicle body 10 is greater than the angle at which the vehicle door 20 is opened relative to the vehicle body 10 at the closing position S1. During the opening process, the vehicle door 20 moves from the closing position S1 to the opening position S3 via the transition position S2. During the closing process, the vehicle door 20 moves from the opening position S3 to the closing position S1 via the transition position S2. Taking the opening process of the vehicle door 20 as an example, during the movement of the vehicle door 20 from the closing position S1 to the transition position S2, the rotating arm 32 and the first mounting member 31 rotate relative to each other, and the rotating arm 32 and the second mounting member 33 rotate relative to each other. During the movement of the vehicle door 20 from the closing position S1 to the transition position S2, the rotating arm 32 and the first mounting member 31 stop rotating relative to each other, and the rotating arm 32 and the second mounting member 33 continue rotating relative to each other, so that the vehicle door 20 moves from the transition position S2 to the opening position S3, and the opening process of the vehicle door 20 is completed.

[0043] Figure 6The motion envelopes of the front door 41 and the rear door 42 of a vehicle with a double-door design without a B-pillar 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 with each other during the opening and closing process. Figure 2 The motion envelopes of the front door 21 and the rear door 22 of this embodiment are shown as an 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 of this embodiment avoids the problem of interference between the front door 21 and the rear door 22 during the opening and closing process. The hinge device 30 of this embodiment can adapt to the requirements of various vehicle models for a B-pillar-free double-door design.

[0044] Please also read Figure 7 and Figure 8 , Figure 7 is a structural schematic diagram of an embodiment of the first driving component of the present application, Figure 8 yes Figure 7 A schematic diagram of the exploded structure of the first drive assembly is shown.

[0045] In one embodiment, the hinge device 30 further includes a first drive assembly 34, which is respectively 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, so that the first mounting member 31 drives the door 20 to open or close 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 driving assembly 34 includes a first power member 341, a first transmission gear 342 and a first transmission gear fan 343. The first power member 341 can be a power element such as a motor. The first transmission gear 342 is transmission-connected to the first power member 341, and the first power member 341 and the first transmission gear 342 are both provided at one of the first mounting member 31 and the rotating arm 32. The first transmission gear fan 343 is meshed with the first transmission gear 342, and the first transmission gear fan 343 is provided at the other of the first mounting member 31 and the rotating arm 32. The first power member 341 drives the first transmission gear fan 343 to rotate through the first transmission gear 342, so as to drive the first mounting member 31 to rotate relative to the rotating arm 32. Figure 7 It is exemplarily shown that the first power member 341 and the first transmission gear 342 are both arranged on the rotating arm 32 , and the first transmission gear sector 343 is arranged on the first mounting member 31 .

[0047] The hinge device 30 further includes a first rotating shaft 35, through which the first mounting member 31 and the rotating arm 32 are rotatably connected, that is, 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, in the axial direction of the first rotating shaft 35, the first power member 341, the first transmission gear 342 and the first transmission gear fan 343 are all located on one side of the first rotating shaft 35. In this way, the present embodiment can realize the transmission design between the first power member 341, the first transmission gear 342 and the first transmission gear fan 343, and then realize the transmission connection between the first driving assembly 34 and the first mounting member 31 and the rotating arm 32 respectively, so that the hinge device 30 can automatically realize the opening and closing of the door 20 through the first driving assembly 34. The first driving assembly 34 also includes a first dust cover 344, which is arranged on one side of the first mounting member 31 and the rotating arm 32, and has a first dust chamber 345 inside. Because the first power member 341, the first transmission gear 342 and the first transmission gear fan 343 are all located on one side of the first rotation shaft 35 in the axial direction of the first rotation shaft 35, the first power member 341, the first transmission gear 342 and the first transmission gear fan 343 can be accommodated in the first dustproof cavity 345. The first dustproof cover 344 can prevent external impurities from entering the first driving assembly 34, which is conducive to ensuring the stability of the first driving assembly 34.

[0049] Please also read Fig. 9 , Fig. 9 It is a structural schematic diagram of another embodiment of the present application in which a vehicle door and a vehicle body are rotatably connected via a hinge device.

[0050] In an alternative embodiment, the first driving assembly 34 includes a first electric telescopic rod 346, and both ends of the first electric telescopic rod 346 are respectively connected to the first mounting member 31 and the rotating arm 32. The first electric telescopic rod 346 is configured to drive the first mounting member 31 to rotate relative to the rotating arm 32, so that the first mounting member 31 drives the door 20 to open or close 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 electric telescopic rod 346.

[0051] Please also read Fig.10 , Fig.10 It is a structural schematic diagram of a vehicle body embodiment of the present application.

[0052] In one embodiment, the first mounting member 31 and the rotating arm 32 are detachably arranged. The vehicle body 10 is further provided with an escape hole 11. The second mounting member 33 is used to be installed inside the vehicle body 10, the escape hole 11 is connected to the inside of the vehicle body 10, and the rotating arm 32 can be movably arranged in the escape 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 the above manner, the vehicle body 10 of this embodiment is provided with an avoidance hole 11 connected to the interior of the vehicle body 10, and the rotating arm 32 can be movably inserted into the avoidance hole 11, so that the rotating arm 32 can be connected to the first mounting member 31 and the second mounting member 33 respectively. In this embodiment, the first mounting member 31 and the rotating arm 32 are detachably arranged, which can facilitate the installation of the hinge device 30, and there is no need for the first mounting member 31 to pass through the avoidance hole 11, allowing the avoidance hole 11 to be designed with a smaller opening area, which is conducive to ensuring the structural strength of the vehicle body 10. If the first mounting member 31 and the rotating arm 32 are not detachable, it means that the entire first mounting member 31 needs to pass through the avoidance hole 11 to be installed on the vehicle door 20, which results in the avoidance hole 11 needing to be designed with a larger opening area, which will weaken the structural strength of the vehicle body 10 to a certain 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 in the C-pillar structure 12 of the vehicle body 10. In this embodiment, at least part of the second mounting member 33 and the rotating arm 32 are located in the C-pillar structure 12 of the vehicle body 10, which not only enhances the structural strength of the vehicle body 10 and improves the safety performance of the overall structure, but also optimizes the structural layout of the hinge device 30, which is conducive to improving space utilization. In addition, the hinge device 30 has a compact structure, which is conducive to 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 adopts a forging process as a whole, which is conducive to ensuring the structural stability and safety of the hinge device 30 and meeting strict automotive industry standards.

[0055] For the example in which the first drive assembly 34 includes the first power member 341, the first transmission gear 342 and the first transmission gear fan 343, the first transmission gear 342 and the first transmission gear fan 343 are detachably arranged, so that the first drive assembly 34 can 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 fan 343 are also disassembled accordingly. The first power member 341 and the first transmission gear 342 can be arranged on the rotating arm 32, and the first power member 341 and the first transmission gear 342 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 arranged with the rotating arm 32, further facilitating the installation of the hinge device 30; the first transmission gear fan 343 can be arranged on the first mounting member 31, and the first transmission gear fan 343 can be disassembled and assembled together with the first mounting member 31, or the first transmission gear fan 343 can also be detachably arranged with the first mounting member 31, further facilitating the installation of the hinge device 30.

[0056] Furthermore, the first transmission gear sector 343 is provided with a first shaft withdrawal hole 3431. In the axial direction of the first rotating shaft 35, the first shaft withdrawal hole 3431 is arranged through the first transmission gear sector 343, and the first shaft withdrawal hole 3431 is arranged opposite to the first rotating shaft 35. When the first mounting member 31 and the rotating arm 32 need to be disassembled, the first rotating shaft 35 can be pushed out from between the first mounting member 31 and the rotating arm 32 through the first shaft withdrawal hole 3431, so that the first mounting member 31 and the rotating arm 32 can be disassembled.

[0057] For the example in which the first driving assembly 34 includes the first electric telescopic rod 346, the two ends of the first electric telescopic rod 346 are detachably connected to the first mounting member 31 and the rotating arm 32, respectively, so that the first driving assembly 34 can 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 disassembled, the two ends of the first electric telescopic rod 346 are also disassembled from the first mounting member 31 and the rotating arm 32, respectively.

[0058] Please also read Fig.11 and Fig.12 , Fig.11 is a structural schematic diagram of an embodiment of the second driving component of the present application, Fig.12 yes Fig.11 A schematic diagram of the exploded structure of the second drive assembly is shown.

[0059] In one embodiment, the hinge device 30 further includes a second drive assembly 36, which is respectively connected to the rotating arm 32 and the second mounting member 33. The second drive assembly 36 is configured to drive the rotating arm 32 to rotate relative to the second mounting member 33, and 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, so that the door 20 is opened and closed automatically.

[0060] Taking the opening process of the vehicle door 20 as an example, in the process of the vehicle door 20 moving from the closed position S1 to the transition position S2, the first driving component 34 drives the relative rotation between the rotating arm 32 and the first mounting member 31, and the second driving component 36 drives the relative rotation between the rotating arm 32 and the second mounting member 33. In the process of the vehicle door 20 moving 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, and the second driving component 36 continues to drive the relative rotation between the rotating arm 32 and the second mounting member 33, so that the vehicle door 20 moves from the transition position S2 to the open position S3, thereby completing the opening process of the vehicle door 20.

[0061] In one embodiment, the second driving assembly 36 includes a second power member 361, a second transmission gear 362 and a second transmission gear fan 363. The second power member 361 can be a power element such as a motor. The second transmission gear 362 is transmission-connected to the second power member 361, and the second power member 361 and the second transmission gear 362 are both disposed on one of the second mounting member 33 and the rotating arm 32. The second transmission gear fan 363 is meshed with the second transmission gear 362, and the second transmission gear fan 363 is disposed on the other of the second mounting member 33 and the rotating arm 32. The second power member 361 drives the second transmission gear fan 363 to rotate through the second transmission gear 362, so as to drive the second mounting member 33 to rotate relative to the rotating arm 32. Fig.11 It is exemplarily shown that the second power member 361 and the second transmission gear 362 are both arranged on the rotating arm 32 , and the second transmission gear sector 363 is arranged on the second mounting member 33 .

[0062] The hinge device 30 further includes a second rotating shaft 37, through which the second mounting member 33 and the rotating arm 32 are rotatably connected, that is, 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, in the axial direction of the second rotating shaft 37, the second power member 361, the second transmission gear 362 and the second transmission gear fan 363 are all located on one side of the second rotating shaft 37. In this way, the present embodiment can realize the transmission design between the second power member 361, the second transmission gear 362 and the second transmission gear fan 363, and then realize the transmission connection between the second driving assembly 36 and the rotating arm 32 and the second mounting member 33 respectively, so that the hinge device 30 can automatically realize the opening and closing of the door 20. The second driving assembly 36 also includes a second dust cover 365, which is arranged on one side of the second mounting member 33 and the rotating arm 32, and the second dust cover 365 has a second dust chamber 366 inside. Because the second power member 361, the second transmission gear 362 and the second transmission gear fan 363 are all located on one side of the second rotation shaft 37 in the axial direction of the second rotation shaft 37, the second power member 361, the second transmission gear 362 and the second transmission gear fan 363 can be accommodated in the second dustproof cavity 366. The second dustproof cover 365 can prevent external impurities from entering the second driving assembly 36, which is conducive to ensuring the stability of the second driving assembly 36.

[0064] In an alternative embodiment, the second driving assembly 36 includes a second electric telescopic rod 364, and both ends of the second electric telescopic rod 364 are respectively connected to the second mounting member 33 and the rotating arm 32. The second electric telescopic rod 364 is configured to drive the second mounting member 33 to rotate relative to the rotating arm 32, so that the second mounting member 33 drives the door 20 to open or close 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 second electric telescopic rod 364.

[0065] In one embodiment, the second mounting member 33 and the rotating arm 32 are detachably arranged, which can facilitate the installation of the hinge device 30. Correspondingly, the rotating arm 32, the second mounting member 33 and the second driving assembly 36 are detachably arranged, so that the second driving assembly 36 can adapt to the detachable design between the second mounting member 33 and the rotating arm 32.

[0066] For the example in which the second drive assembly 36 includes the second power member 361, the second transmission gear 362 and the second transmission gear sector 363, the second transmission gear 362 and the second transmission gear sector 363 are detachably arranged, so that the second drive assembly 36 can 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 the second rotating shaft 37. After the second mounting member 33 and the rotating arm 32 are disassembled, the second transmission gear 362 and the second transmission gear sector 363 are also disassembled accordingly. The second power member 361 and the second transmission gear 362 can be arranged on the rotating arm 32, and the second power member 361 and the second transmission gear 362 can be disassembled and assembled together with the rotating arm 32, or the second power member 361 and the second transmission gear 362 can also be detachably arranged with the rotating arm 32, further facilitating the installation of the hinge device 30; the second transmission gear fan 363 can be arranged on the second mounting member 33, and the second transmission gear fan 363 can be disassembled and assembled together with the second mounting member 33, or the second transmission gear fan 363 can also be detachably arranged with the second mounting member 33, further facilitating the installation of the hinge device 30.

[0067] Furthermore, the second transmission gear sector 363 is provided with a second shaft withdrawal hole 3631. In the axial direction of the second rotating shaft 37, the second shaft withdrawal hole 3631 is arranged through the second transmission gear sector 363, and the second shaft withdrawal hole 3631 is arranged opposite to the second rotating shaft 37. When the second mounting member 33 and the rotating arm 32 need to be disassembled, the second rotating shaft 37 can be pushed out from between the second mounting member 33 and the rotating arm 32 through the second shaft withdrawal hole 3631, so that the second mounting member 33 and the rotating arm 32 can be disassembled.

[0068] For the example in which the second driving assembly 36 includes the second electric telescopic rod 364, the two ends of the second electric telescopic rod 364 are detachably connected to the second mounting member 33 and the rotating arm 32, respectively, so that the second driving assembly 36 can adapt to the detachable design between the second mounting member 33 and the rotating arm 32. After the second mounting member 33 and the rotating arm 32 are detached, the two ends of the second electric telescopic rod 364 are also detached from the second mounting member 33 and the rotating arm 32, respectively.

[0072] The rotating arm 32 is rotatably connected to the first mounting member 31 and the second mounting member 33 respectively, that is, the hinge device 30 adopts a double rotating shaft design, which can reduce the risk of interference between the door 20 and other structures during the opening and closing process. In particular, for the case where the vehicle adopts a double-door design without a B-pillar, the hinge device 30 can reduce the risk of interference between the doors 20. In addition, the hinge device 30 also includes a first drive component 34, which drives the first mounting member 31 to rotate relative to the rotating arm 32, so that the first mounting member 31 drives the door 20 to open or close relative to the vehicle body 10, that is, the hinge device 30 can automatically realize the opening and closing of the door 20 through the first drive component 34.

[0073] Embodiment 2:

[0074] The first driving assembly 34 includes a first power member 341, a first transmission gear 342 and a first transmission gear fan 343. The first power member 341 can be a power element such as a motor. The first transmission gear 342 is transmission-connected to the first power member 341, and the first power member 341 and the first transmission gear 342 are both disposed on one of the first mounting member 31 and the rotating arm 32. The first transmission gear fan 343 is meshed with the first transmission gear 342, and the first transmission gear fan 343 is disposed on the other of the first mounting member 31 and the rotating arm 32. The first power member 341 drives the first transmission gear fan 343 to rotate through the first transmission gear 342, so as to drive the first mounting member 31 to rotate relative to the rotating arm 32.

[0075] The hinge device 30 further includes a first rotating shaft 35, through which the first mounting member 31 and the rotating arm 32 are rotatably connected, that is, 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.

In this embodiment, the first mounting member 31 and the rotating arm 32 are detachably arranged, which can facilitate the installation of the hinge device 30, and there is no need for the first mounting member 31 to pass through the avoidance hole 11, allowing the avoidance hole 11 to be designed with a smaller opening area, which is beneficial to ensure the structural strength of the vehicle body 10. If the first mounting member 31 and the rotating arm 32 are not detachable, it means that the entire first mounting member 31 needs to pass through the avoidance hole 11 to be installed on the vehicle door 20, which results in the avoidance hole 11 needing to be designed with a larger opening area, which will weaken the structural strength of the vehicle body 10 to a certain extent.
