[0034] See also Figures 1 to 3 , Figure 1 is a structural schematic diagram of an embodiment of a vehicle of the present application, Figure 2 yes Figure 1 The schematic diagram of the structure of another state of the vehicle shown, Figure 3 It is a schematic diagram of the motion envelope of the first door and the second door of the vehicle of the present application.
[0035] In one embodiment, a vehicle includes a vehicle body 10 and a first door 20, and the first door 20 is rotatably connected to the vehicle body 10 through a hinge device 30. The vehicle can adopt a double-door design without a B-pillar, specifically, the vehicle also includes a second door 40, the first door 20 and the second door 40 are located on the same side of the vehicle body 10, the side of the first door 20 away from the second door 40 is rotatably connected to the vehicle body 10, and the side of the second door 40 away from the first door 20 is rotatably connected to the vehicle body 10, that is, the first door 20 and the second door 40 are double-door structures. The first door 20 can be arranged near the rear of the vehicle, that is, the first door 20 is the rear door of the vehicle. Correspondingly, the second door 40 can be arranged near the front of the vehicle, that is, the second door 40 is the front door of the vehicle.
[0036] Of course, in other embodiments of the present application, the second door 40 and the vehicle body 10 may also be rotatably connected via the hinge device 30. Furthermore, the first door 20 may be disposed near the front of the vehicle, i.e., the first door 20 is the front door of the vehicle, and the second door 40 may be disposed near the rear of the vehicle, i.e., the second door 40 is the rear door of the vehicle. In addition, the vehicle of the present application is not limited to a design of double-doors without a B-pillar. For example, the side of the first door 20 close to the second door 40 may be rotatably connected to the vehicle body 10, and the side of the second door 40 away from the first door 20 may be rotatably connected to the vehicle body 10, etc., or the vehicle may adopt a design of double-doors with a B-pillar, etc., which are not limited here.
[0037] The hinge device 30 according to the embodiment of the present application is described below.
[0038] Please also read Figure 4 and Figure 5 , Figure 4 is a structural schematic diagram of an embodiment of the hinge device of the present application, Figure 5 It is a schematic diagram of the exploded structure of an embodiment of the hinge device of the present application.
[0039] In one embodiment, the hinge device 30 includes a first mounting member 31, which is mounted on the vehicle body 10. The hinge device 30 also includes a rotating arm assembly 32, which is rotatably connected to the first mounting member 31. The hinge device 30 also includes a second mounting member 33, which is mounted on the first vehicle door 20, and the second mounting member 33 is rotatably connected to the rotating arm assembly 32.
[0040] In the above manner, the rotating arm assembly 32 of the present embodiment is rotatably connected to the first mounting member 31 and the second mounting member 33 respectively, that is, the hinge device 30 of the present embodiment adopts a double rotation axis design. The connection between the rotating arm assembly 32 and the first mounting member 31 has a first rotation axis O1, and the rotating arm assembly 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 assembly 32 and the second mounting member 33 has a second rotation axis O2, and the rotating arm assembly 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 the present embodiment constrains the motion trajectory of the first door 20 through the cooperation of the first rotation axis O1 and the second rotation axis O2, so that the first door 20 can achieve a specific compound motion during the opening and closing process, and can reduce the risk of the first door 20 interfering with 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 of the present embodiment can reduce the risk of the first door 20 interfering with other doors (such as the second door 40 mentioned above). In other words, this embodiment constrains the movement trajectory of the first door 20 by the hinge device 30, which is not limited to the first door 20 avoiding other doors to avoid interference. The first door 20 can also avoid other structures of the vehicle except the door, which is not limited here.
[0041] For example, Figure 1 and Figure 2 As shown, the movement trajectory of the first door 20 in this embodiment includes a closed position S1, a transition position S2, and an open position S3. The angle at which the first door 20 is opened relative to the vehicle body 10 at the open position S3 is greater than the angle at which the first door 20 is opened relative to the vehicle body 10 at the closed position S1. The first door 20 moves from the closed position S1 to the open position S3 via the transition position S2 during the opening process, and moves from the open position S3 to the closed position S1 via the transition position S2 during the closing process. Taking the opening process of the first door 20 as an example, when the first door 20 moves from the closed position S1 to the transition position S2, the rotating arm assembly 32 and the first mounting member 31 rotate relative to each other, and the rotating arm assembly 32 and the second mounting member 33 rotate relative to each other. When the first door 20 moves from the closed position S1 to the transition position S2, the rotating arm assembly 32 and the first mounting member 31 stop rotating relative to each other, while the rotating arm assembly 32 and the second mounting member 33 continue rotating relative to each other, so that the first door 20 moves from the transition position S2 to the open position S3, thereby completing the opening process of the first door 20.
[0042] Figure 6The motion envelopes of the front door 51 and the rear door 52 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 51 and the rear door 52 overlap, which makes it easy for the front door 51 and the rear door 52 to interfere with each other during the opening and closing process. Figure 3 The motion envelopes of the first door 20 and the second door 40 of this embodiment are shown as an example. It can be seen that the motion envelopes of the first door 20 and the second door 40 do not overlap, and the hinge device 30 of this embodiment avoids the problem of interference between the first door 20 and the second door 40 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.
[0043] Please also read Figure 7 and Figure 8 , Figure 7 This is a schematic structural diagram of an embodiment of the hinge device of the present application installed on a vehicle body. Figure 8 yes Figure 7 The hinge device shown is installed on the vehicle body in another state.
[0044] In one embodiment, the vehicle body 10 is further provided with an avoidance hole 11. The first mounting member 31 is mounted inside the vehicle body 10, the avoidance hole 11 is connected to the inside of the vehicle body 10, and the rotating arm assembly 32 is movably arranged in the avoidance hole 11, so that the rotating arm assembly 32 can be rotatably connected to the first mounting member 31 and the second mounting member 33 respectively. The second mounting member 33 and the rotating arm assembly 32 are detachably arranged.
[0045] In addition, the vehicle body 10 of this embodiment is also provided with an avoidance hole 11 connected to the interior of the vehicle body 10, and the rotating arm assembly 32 can be movably inserted into the avoidance hole 11, so that the rotating arm assembly 32 can be connected to the first mounting member 31 and the second mounting member 33 respectively. In this embodiment, the second mounting member 33 and the rotating arm assembly 32 are detachably arranged, which can facilitate the installation of the hinge device 30, and the second mounting member 33 does not need 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 second mounting member 33 and the rotating arm assembly 32 are not detachable, it means that the entire second mounting member 33 needs to pass through the avoidance hole 11 to be installed on the first 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.
[0046] Of course, in other embodiments of the present application, the rotating arm assembly 32 and the first mounting member 31 are detachably arranged, which can further facilitate the installation of the hinge device 30, and is not limited here.
[0047] Please also refer to Fig. 9For the example in which the first door 20 is the rear door of the vehicle, the first mounting member 31 is installed in the C-pillar structure 12 of the vehicle body 10. In this embodiment, at least part of the first mounting member 31 and the rotating arm assembly 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 is forged as a whole, which is conducive to ensuring the structural stability and safety of the hinge device 30 and meeting strict automotive industry standards.
[0048] In one embodiment, the rotating arm assembly 32 includes a first rotating arm 321 and a second rotating arm 322. The first rotating arm 321 is rotatably connected to the first mounting member 31 and the second mounting member 33, respectively, and the second rotating arm 322 is rotatably connected to the first mounting member 31 and the second mounting member 33, respectively. The first rotating arm 321 and the second rotating arm 322 can rotate relative to the first mounting member 31 around the first rotation axis O1, and the first rotating arm 321 and the second rotating arm 322 can rotate relative to the second mounting member 33 around the second rotation axis O2. The first rotating arm 321 and the second mounting member 33 are detachably arranged, and the second rotating arm 322 and the second mounting member 33 are detachably arranged, so that the rotating arm assembly 32 and the second mounting member 33 are detachably arranged. The avoidance hole 11 includes a first avoidance hole 111 and a second avoidance hole 112 spaced apart from each other, the first rotating arm 321 can be movably penetrated in the first avoidance hole 111, and the second rotating arm 322 can be movably penetrated in the second avoidance hole 112.
[0049] In the above manner, the rotating arm assembly 32 is connected to the first mounting member 31 and the second mounting member 33 through the first rotating arm 321 and the second rotating arm 322, respectively, and the first rotating arm 321 and the second rotating arm 322 can cooperate to improve the connection strength. In addition, the avoidance holes 11 are designed for the first rotating arm 321 and the second rotating arm 322, namely the first avoidance hole 111 and the second avoidance hole 112, respectively, so that the avoidance hole 11 can have a smaller opening area under the premise of ensuring the overall structural stability of the hinge device 30, which is conducive to ensuring the structural strength of the vehicle body 10. If only one avoidance hole 11 is designed, the first rotating arm 321 and the second rotating arm 322 both pass through the avoidance hole 11 to connect to the second mounting member 33, and the opening area of the avoidance hole 11 is bound to be larger than the sum of the opening areas of the first avoidance hole 111 and the second avoidance hole 112, which will undoubtedly weaken the structural strength of the vehicle body 10.
[0050] Figure 7The state of the first rotating arm 321 and the second rotating arm 322 when the first door 20 is closed is shown. Figure 8 The state of the first rotating arm 321 and the second rotating arm 322 when the first door 20 is opened is shown.
[0051] Furthermore, the first rotating arm 321 and the second rotating arm 322 are spaced apart along the height direction of the vehicle body 10. Correspondingly, the first avoidance hole 111 and the second avoidance hole 112 are also spaced apart along the height direction of the vehicle body 10, so that the first rotating arm 321 can be movably disposed in the first avoidance hole 111, and the second rotating arm 322 can be movably disposed in the second avoidance hole 112.
[0052] Optionally, both the first rotating arm 321 and the second rotating arm 322 may be in a gooseneck shape, etc., which is not limited here.
[0053] Please also read Fig.10 and Fig.11 , Fig.10 is a schematic structural diagram of an embodiment of a rotating arm assembly of the present application, Fig.11 It is a structural schematic diagram of an embodiment of the second mounting member of the present application.
[0054] In one embodiment, the rotating arm assembly 32 further includes a first rotating connection member 325 and a second rotating connection member 326. The first rotating arm 321 is provided with a first connection hole 3211, the second mounting member 33 is provided with a second connection hole 331, and the first rotating connection member 325 is detachably inserted through the first connection hole 3211 and the second connection hole 331, so that the first rotating arm 321 is rotatably connected to the second mounting member 33. The second rotating arm 322 is provided with a third connection hole 3221, the second mounting member 33 is provided with a fourth connection hole 332, and the second rotating connection member 326 is detachably inserted through the third connection hole 3221 and the fourth connection hole 332, so that the second rotating arm 322 is rotatably connected to the second mounting member 33. The central axis of the first rotating connection member 325 and the central axis of the second rotating connection member 326 both coincide with the second rotation axis O2.
[0055] In one embodiment, the rotating arm assembly 32 further includes a third rotating connection member 327. The third rotating connection member 327 is disposed through the first mounting member 31, the first rotating arm 321 and the second rotating arm 322, so that the first rotating arm 321 and the second rotating arm 322 are both rotatably connected to the first mounting member 31. The central axis of the third rotating connection member 327 coincides with the first rotating axis O1.
[0056] In one embodiment, the first mounting member 31 includes a mounting seat 311 and a connecting arm 312. The mounting seat 311 is used to connect with the vehicle body 10, and the connecting arm 312 is protruding from the mounting seat 311, and the connecting arm 312 is rotatably connected with the rotating arm assembly 32. Specifically, the first rotating arm 321 and the second rotating arm 322 are both rotatably connected with the connecting arm 312 through the third rotating connecting member 327. The mounting seat 311 is used to abut against the rotating arm assembly 32 to limit the rotation of the rotating arm assembly 32. During the closing process of the first door 20, the first door 20 moves from the transition position to the closed position, and at this time, the rotating arm assembly 32 rotates toward the first mounting member 31 until the first rotating arm 321 and the second rotating arm 322 abut against the mounting seat 311, and the mounting seat 311 limits the first rotating arm 321 and the second rotating arm 322 from further rotating.
[0057] In one embodiment, the rotating arm assembly 32 further includes a first support member 323, which is detachably supported between the first rotating arm 321 and the second rotating arm 322. The first support member 323 is configured to enhance the structural strength of the rotating arm assembly 32, thereby facilitating the overall structural stability of the hinge device 30. Furthermore, the first support member 323 and the first rotating arm 321 and the second rotating arm 322 are detachably arranged, which means that during the installation process of the hinge device 30, the first support member 323 does not need to pass through the avoidance hole 11, further allowing the avoidance hole 11 to be designed with a smaller opening area, thereby facilitating the structural strength of the vehicle body 10.
[0058] Specifically, the first support member 323 is arranged close to the second mounting member 33. In this embodiment, the first support member 323 is arranged to be detachably supported between the first rotating arm 321 and the second rotating arm 322, and the first support member 323 and the first rotating arm 321 and the second rotating arm 322 are detachably arranged, which means that during the installation process of the hinge device 30, the first support member 323 does not need to pass through the avoidance hole 11, and further allows 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. In particular, for the case where the first support member 323 is arranged close to the second mounting member 33 in this embodiment, if the first rotating arm 321 and the second rotating arm 322 are not detachable from the second mounting member 33, the first support member 323 must be required to pass through the avoidance hole 11 during the installation process of the hinge device 30, resulting in the need to design a larger opening area for the avoidance hole 11, which weakens the structural strength of the vehicle body 10.
[0059] In one embodiment, the rotating arm assembly 32 further includes a second support member 324, which is supported between the first rotating arm 321 and the second rotating arm 322, and the second support member 324 is disposed close to the first mounting member 31. In this embodiment, the first support member 323 and the second support member 324 cooperate to enhance the structural strength of the rotating arm assembly 32, thereby facilitating the overall structural stability of the hinge device 30.

Specifically, the rotating arm assembly 32 further includes a fourth rotating connection member 328 and a fifth rotating connection member 329. The first rotating arm 321 is provided with a fifth connection hole 3212, the first mounting member 31 is provided with a sixth connection hole 313, and the fourth rotating connection member 328 is detachably penetrated through the fifth connection hole 3212 and the sixth connection hole 313, so that the first rotating arm 321 is rotatably connected with the first mounting member 31. The second rotating arm 322 is provided with a seventh connection hole 3222, the first mounting member 31 is provided with an eighth connection hole 314, and the fifth rotating connection member 329 is detachably penetrated through the seventh connection hole 3222 and the eighth connection hole 314, so that the second rotating arm 322 is rotatably connected with the first mounting member 31.
[0062] In one embodiment, a hinge device 30 is provided. The hinge device 30 includes a first mounting member 31, and the first mounting member 31 is used to connect to the vehicle body 10. The hinge device 30 also includes a rotating arm assembly 32, and the rotating arm assembly 32 is rotatably connected to the first mounting member 31.
