[0033] 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 the vehicle body. The hinge device also includes a rotating arm assembly rotatably connected to the first mounting member. The hinge device further includes a second mounting member for connection to the vehicle door, and the second mounting member is rotatably connected to the rotating arm assembly. The second mounting member and the rotating arm assembly are detachably configured. This will be described in detail below.

[0034] Please see Figures 1 to 3 , Figure 1 This is a structural schematic diagram of one embodiment of the vehicle described in this application. Figure 2 yes Figure 1 A structural schematic diagram of another state of the vehicle shown. Figure 3 This is a schematic diagram of the motion envelope of the first and second doors of the vehicle in this application.

[0035] In one embodiment, the vehicle includes a body 10 and a first door 20, which is rotatably connected to the body 10 via a hinge device 30. The vehicle may employ a pillarless, double-door design; 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 body 10. The side of the first door 20 away from the second door 40 is rotatably connected to the body 10, and the side of the second door 40 away from the first door 20 is also rotatably connected to the body 10. That is, the first door 20 and the second door 40 are double-door structures. The first door 20 may be located near the rear of the vehicle, i.e., the first door 20 is the rear door of the vehicle. Correspondingly, the second door 40 may be located near the front of the vehicle, i.e., the second door 40 is the front door of the vehicle.

[0036] Of course, in other embodiments of this application, the second door 40 can also be rotatably connected to the vehicle body 10 via a hinge device 30. Furthermore, the first door 20 can be positioned closer to the front of the vehicle, i.e., the first door 20 is the front door of the vehicle, and the second door 40 can be positioned closer to the rear of the vehicle, i.e., the second door 40 is the rear door of the vehicle. In addition, the vehicle in this application is not limited to a pillarless double-door design; for example, the side of the first door 20 closest to the second door 40 can be rotatably connected to the vehicle body 10, and the side of the second door 40 furthest from the first door 20 can be rotatably connected to the vehicle body 10, or the vehicle can employ a double-door design with a B-pillar, etc., which are not limited here.

[0037] The hinge device 30 of the present application embodiment will be described below.

[0038] Please refer to the following: Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of a hinge device according to an embodiment of the present application. Figure 5 This is an exploded structural diagram of an embodiment of the hinge device of this application.

[0039] In one embodiment, the hinge device 30 includes a first mounting member 31 mounted on the vehicle body 10. The hinge device 30 also includes a rotating arm assembly 32 rotatably connected to the first mounting member 31. The hinge device 30 further includes a second mounting member 33 mounted on the first door 20 and rotatably connected to the rotating arm assembly 32.

[0040] In this embodiment, the rotating arm assembly 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-axis design. The connection between the rotating arm assembly 32 and the first mounting member 31 has a first axis of rotation O1, allowing relative rotation between them. The connection between the rotating arm assembly 32 and the second mounting member 33 has a second axis of rotation O2, allowing relative rotation between them. Thus, 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 first door 20, enabling the first door 20 to achieve specific composite movements during opening and closing, reducing the risk of interference between the first door 20 and other structures. This is particularly beneficial for vehicles with pillarless split-door designs, where the hinge device 30 reduces the risk of interference between the first door 20 and other doors (such as the aforementioned second door 40). In other words, in this embodiment, the movement trajectory of the first door 20 is constrained by the hinge device 30. It is not limited to the first door 20 avoiding other doors to avoid interference. It can also be the first door 20 avoiding other structures of the vehicle other than the doors. This is not limited here.

[0041] For example, such as 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. In the open position S3, the angle at which the first door 20 opens relative to the vehicle body 10 is greater than the angle at which the first door 20 opens relative to the vehicle body 10 in the closed position S1. During the opening process, the first door 20 moves from the closed position S1 through the transition position S2 to the open position S3, and during the closing process, the first door 20 moves from the open position S3 through the transition position S2 to the closed position S1. Taking the opening process of the first door 20 as an example, during the process of the first door 20 moving 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. During the process of the first door 20 moving 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 to rotate relative to each other, so that the first door 20 moves from the transition position S2 to the open position S3, thus 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 pillarless double-door design 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 during the opening and closing process. Figure 3 The motion envelopes of the first door 20 and the second door 40 in this embodiment are illustrated by way of example. It can be seen that the motion envelopes of the first door 20 and the second door 40 do not overlap. The hinge device 30 in this embodiment avoids the problem of interference between the first door 20 and the second door 40 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.

[0043] Please refer to the following: Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of an embodiment of the hinge device of this application installed on a vehicle body. Figure 8 yes Figure 7 The diagram shows the hinge device installed in another state of the vehicle body.

[0044] In one embodiment, the vehicle body 10 also has a clearance hole 11. The first mounting member 31 is installed inside the vehicle body 10, the clearance hole 11 communicates with the interior of the vehicle body 10, and the rotating arm assembly 32 is movably inserted through the clearance 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 connected.

[0045] Furthermore, in this embodiment, the vehicle body 10 also has a clearance hole 11 communicating with the interior of the vehicle body 10. The rotating arm assembly 32 is movably inserted through the clearance hole 11, allowing the rotating arm assembly 32 to 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 connected, which facilitates the installation of the hinge device 30 and eliminates the need for the second mounting member 33 to pass through the clearance hole 11. This allows the clearance hole 11 to be designed with a smaller opening area, thereby helping to ensure the structural strength of the vehicle body 10. If the second mounting member 33 and the rotating arm assembly 32 were not detachable, it would mean that the entire second mounting member 33 would need to pass through the clearance hole 11 to be installed on the first door 20. This would require the clearance hole 11 to be designed with a larger opening area, which would weaken the structural strength of the vehicle body 10 to some extent.

[0046] Of course, in other embodiments of this application, the rotating arm assembly 32 and the first mounting member 31 are detachably connected, which can further facilitate the installation of the hinge device 30, and is not limited here.

[0047] It should be noted that please refer to the following as well. Figure 9In the example where the first door 20 is the rear door of the vehicle, the first mounting member 31 is installed within the C-pillar structure 12 of the vehicle body 10. In this embodiment, at least a portion of the first mounting member 31 and the rotating arm assembly 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, thus improving space utilization. Furthermore, the compact structure of the hinge device 30 facilitates its installation design by embedding it into 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 ensure the structural stability and safety of the hinge device 30, meeting stringent 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 a first mounting member 31 and a second mounting member 33, respectively, and the second rotating arm 322 is rotatably connected to both the first mounting member 31 and the second mounting member 33. The first rotating arm 321 and the second rotating arm 322 are detachably connected to the first mounting member 31 about a first rotation axis O1, and the first rotating arm 321 and the second rotating arm 322 are detachably connected to the second mounting member 33 about a second rotation axis O2. The first rotating arm 321 and the second mounting member 33 are detachably connected, thus enabling the rotating arm assembly 32 and the second mounting member 33 to be detachably connected. The clearance hole 11 includes a first clearance hole 111 and a second clearance hole 112 spaced apart from each other. The first rotating arm 321 is movably inserted through the first clearance hole 111, and the second rotating arm 322 is movably inserted through the second clearance 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 respectively through the first rotating arm 321 and the second rotating arm 322. The first rotating arm 321 and the second rotating arm 322 can cooperate to improve the connection strength. Furthermore, avoidance holes 11 are designed for the first rotating arm 321 and the second rotating arm 322 respectively, namely the first avoidance hole 111 and the second avoidance hole 112. Under the premise of ensuring the overall structural stability of the hinge device 30, the avoidance hole 11 has a small opening area, which is beneficial 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. The opening area of ​​the avoidance hole 11 will inevitably 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 diagram shows the states of the first rotating arm 321 and the second rotating arm 322 when the first door 20 is closed. Figure 8 The state of the first rotating arm 321 and the second rotating arm 322 is shown when the first door 20 is opened.

[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 clearance hole 111 and the second clearance 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 inserted through the first clearance hole 111 and the second rotating arm 322 can be movably inserted through the second clearance hole 112.

[0052] Optionally, both the first rotating arm 321 and the second rotating arm 322 can be shaped like a gooseneck, etc., which is not limited here.

[0053] Please refer to the following: Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of the structure of one embodiment of the rotating arm assembly of this application. Figure 11 This is a structural schematic diagram of an embodiment of the second mounting component of this application.

[0054] In one embodiment, the rotating arm assembly 32 further includes a first rotating connector 325 and a second rotating connector 326. The first rotating arm 321 has a first connecting hole 3211, and the second mounting member 33 has a second connecting hole 331. The first rotating connector 325 is detachably inserted through the first connecting hole 3211 and the second connecting hole 331, thereby rotatably connecting the first rotating arm 321 to the second mounting member 33. The second rotating arm 322 has a third connecting hole 3221, and the second mounting member 33 has a fourth connecting hole 332. The second rotating connector 326 is detachably inserted through the third connecting hole 3221 and the fourth connecting hole 332, thereby rotatably connecting the second rotating arm 322 to the second mounting member 33. The central axis of both the first rotating connector 325 and the second rotating connector 326 coincides with the second rotation axis O2.

[0055] In one embodiment, the rotating arm assembly 32 further includes a third rotating connector 327. The third rotating connector 327 passes through the first mounting member 31, the first rotating arm 321, and the second rotating arm 322, such that both the first rotating arm 321 and the second rotating arm 322 are rotatably connected to the first mounting member 31. The central axis of the third rotating connector 327 coincides with the first rotation axis O1.

[0056] In one embodiment, the first mounting member 31 includes a mounting base 311 and a connecting arm 312. The mounting base 311 is used to connect to the vehicle body 10, and the connecting arm 312 protrudes from the mounting base 311 and is rotatably connected to the rotating arm assembly 32. Specifically, the first rotating arm 321 and the second rotating arm 322 are both rotatably connected to the connecting arm 312 through a third rotating connector 327. The mounting base 311 is used to abut against the rotating arm assembly 32 to restrict 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. 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 base 311, and the mounting base 311 restricts the first rotating arm 321 and the second rotating arm 322 from further rotation.

[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 helping to ensure the overall structural stability of the hinge device 30. Furthermore, the first support member 323 is detachably disposed from the first rotating arm 321 and the second rotating arm 322, meaning that during the installation of the hinge device 30, the first support member 323 does not need to pass through the clearance hole 11, further allowing the clearance hole 11 to be designed with a smaller opening area, thereby helping to ensure the structural strength of the vehicle body 10.

[0058] Specifically, the first support member 323 is positioned close to the second mounting member 33. In this embodiment, the first support member 323 is detachably supported between the first rotating arm 321 and the second rotating arm 322. This detachable arrangement means that during the installation of the hinge device 30, the first support member 323 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. Especially in this embodiment where the first support member 323 is positioned close to the second mounting member 33, if the first rotating arm 321 and the second rotating arm 322 were not detachable from the second mounting member 33, the first support member 323 would inevitably need to pass through the clearance hole 11 during the installation of the hinge device 30, requiring a larger opening area in the clearance hole 11 and weakening 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 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 helping to ensure the overall structural stability of the hinge device 30.

[0060] Please refer to the following: Figure 12 and Figure 13 , Figure 12 This is an exploded structural diagram of another embodiment of the hinge device of this application. Figure 13 This is a schematic diagram of the structure of an embodiment of the first mounting component of this application.

[0061] In an alternative embodiment, the rotating arm assembly 32 is detachably connected to the first mounting member 31. Specifically, the rotating arm assembly 32 further includes a fourth rotating connector 328 and a fifth rotating connector 329. The first rotating arm 321 has a fifth connecting hole 3212, and the first mounting member 31 has a sixth connecting hole 313. The fourth rotating connector 328 is detachably inserted through the fifth connecting hole 3212 and the sixth connecting hole 313, thereby rotatably connecting the first rotating arm 321 to the first mounting member 31. The second rotating arm 322 has a seventh connecting hole 3222, and the first mounting member 31 has an eighth connecting hole 314. The fifth rotating connector 329 is detachably inserted through the seventh connecting hole 3222 and the eighth connecting hole 314, thereby rotatably connecting the second rotating arm 322 to 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 for connection to the body 10 of a vehicle. The hinge device 30 also includes a rotating arm assembly 32 rotatably connected to the first mounting member 31. The hinge device 30 further includes a second mounting member 33 for connection to a first door 20 of the vehicle, and the second mounting member 33 is rotatably connected to the rotating arm assembly 32, and the second mounting member 33 and the rotating arm assembly 32 are detachably disposed.

[0063] In this manner, the rotating arm assembly 32 of the hinge device 30 is rotatably connected to both the first mounting member 31 and the second mounting member 33. That is, the hinge device 30 in this embodiment adopts a dual-rotation-axis design, which reduces the risk of interference between the first door 20 and other structures during opening and closing. Especially for vehicles with a pillarless, double-door design, the hinge device 30 in this embodiment can reduce the risk of interference between the first door 20 and other doors. Furthermore, the second mounting member 33 and the rotating arm assembly 32 are detachably connected, facilitating the installation of the hinge device 30.

[0064] It should be noted that the hinge device 30 described in this embodiment can be applied to the vehicle described in the above embodiments, and will not be described again here.

[0065] The technical solutions provided in the embodiments of this application will be described below with reference to specific examples.

[0066] Example 1:

[0067] The vehicle includes a body 10 with a clearance hole 11. The vehicle also includes a first door 20, which is rotatably connected to the body 10 via a hinge device 30. The hinge device 30 includes a first mounting member 31, which is installed inside the body 10. The hinge device 30 also includes a rotating arm assembly 32, which is rotatably connected to the first mounting member 31 and movably passes through the clearance hole 11. The hinge device 30 further includes a second mounting member 33, which is installed on the first door 20 and rotatably connected to the rotating arm assembly 32. The second mounting member 33 and the rotating arm assembly 32 are detachably connected.

[0068] The rotating arm assembly 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-axis rotation design. The connection between the rotating arm assembly 32 and the first mounting member 31 has a first axis of rotation O1, allowing relative rotation between them. The connection between the rotating arm assembly 32 and the second mounting member 33 has a second axis of rotation O2, allowing relative rotation between them. 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 first door 20, enabling the first door 20 to achieve specific composite movements during opening and closing, thus reducing the risk of interference between the first door 20 and other structures. This is particularly beneficial for vehicles with pillarless, double-door designs, where the hinge device 30 reduces the risk of interference between the first door 20 and other doors (such as the aforementioned second door 40). The second mounting member 33 is detachably connected to the rotating arm assembly 32, which facilitates the installation of the hinge device 30 and eliminates the need for the second mounting member 33 to pass through the clearance hole 11. This allows for a smaller opening area in the clearance hole 11, which in turn helps to ensure the structural strength of the vehicle body 10.

[0069] Example 2:

[0070] 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 both the first mounting member 31 and the second mounting member 33, and the second rotating arm 322 is also rotatably connected to both the first mounting member 31 and the second mounting member 33. The first rotating arm 321 and the second mounting member 33 are detachably connected, and the second rotating arm 322 and the second mounting member 33 are also detachably connected, thus enabling the rotating arm assembly 32 and the second mounting member 33 to be detachably connected. The clearance hole 11 includes a first clearance hole 111 and a second clearance hole 112 spaced apart from each other. The first rotating arm 321 is movably inserted through the first clearance hole 111, and the second rotating arm 322 is movably inserted through the second clearance hole 112.

[0071] The rotating arm assembly 32 is connected to the first mounting member 31 and the second mounting member 33 via the first rotating arm 321 and the second rotating arm 322, respectively. The first rotating arm 321 and the second rotating arm 322 can cooperate to improve the connection strength. Furthermore, clearance holes 11, namely the first clearance hole 111 and the second clearance hole 112, are designed for the first rotating arm 321 and the second rotating arm 322, respectively. This allows the clearance holes 11 to have a small opening area while ensuring the overall structural stability of the hinge device 30, which is beneficial to ensuring the structural strength of the vehicle body 10.

[0072] Example 3:

[0073] The rotating arm assembly 32 also includes a first support member 323, which is detachably supported between the first rotating arm 321 and the second rotating arm 322, and is positioned close to the second mounting member 33. The first support member 323 is configured to enhance the structural strength of the rotating arm assembly 32, thereby contributing to the overall structural stability of the hinge device 30. Furthermore, the first support member 323 is detachably mounted from the first rotating arm 321 and the second rotating arm 322, meaning that during the installation of the hinge device 30, the first support member 323 does not need to pass through the clearance hole 11, further allowing for a smaller opening area in the clearance hole 11, which in turn helps to ensure the structural strength of the vehicle body 10.

[0074] Example 4:

[0075] The hinge device 30 includes a first mounting member 31 for connection to the vehicle body 10. The hinge device 30 also includes a rotating arm assembly 32 rotatably connected to the first mounting member 31. The hinge device 30 further includes a second mounting member 33 for connection to a vehicle door, and the second mounting member 33 is rotatably connected to the rotating arm assembly 32. The second mounting member 33 and the rotating arm assembly 32 are detachably disposed.

[0076] The rotating arm assembly 32 of the hinge device 30 is rotatably connected to both the first mounting member 31 and the second mounting member 33. This means the hinge device 30 employs a dual-axis design, which reduces the risk of interference between the door 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 doors. Furthermore, the second mounting member 33 is detachably connected to the rotating arm assembly 32, facilitating the installation of the hinge device 30.

[0077] Example 5:

[0078] 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 both the first mounting member 31 and the second mounting member 33, and the second rotating arm 322 is also rotatably connected to both the first mounting member 31 and the second mounting member 33. The first rotating arm 321 and the second mounting member 33 are detachably connected, and the second rotating arm 322 and the second mounting member 33 are also detachably connected, thus enabling the rotating arm assembly 32 and the second mounting member 33 to be detachably connected.

[0079] The clearance hole 11 includes a first clearance hole 111 and a second clearance hole 112 spaced apart from each other. A first rotating arm 321 is movably inserted through the first clearance hole 111, and a second rotating arm 322 is movably inserted through the second clearance hole 112. The rotating arm assembly 32 is connected to the first mounting member 31 and the second mounting member 33 respectively through the first rotating arm 321 and the second rotating arm 322. The first rotating arm 321 and the second rotating arm 322 can cooperate to improve the connection strength. Furthermore, clearance holes 11 are designed for the first rotating arm 321 and the second rotating arm 322 respectively, i.e., first clearance hole 111 and second clearance hole 112. This allows the clearance holes 11 to have a smaller opening area while ensuring the overall structural stability of the hinge device 30, which is beneficial to ensuring the structural strength of the vehicle body 10.

[0080] Example 6:

[0081] The rotating arm assembly 32 also includes a first support member 323, which is detachably supported between the first rotating arm 321 and the second rotating arm 322, and is positioned close to the second mounting member 33. The first support member 323 is configured to enhance the structural strength of the rotating arm assembly 32, thereby contributing to the overall structural stability of the hinge device 30. Furthermore, the first support member 323 is detachably mounted from the first rotating arm 321 and the second rotating arm 322, meaning that during the installation of the hinge device 30, the first support member 323 does not need to pass through the clearance hole 11, further allowing for a smaller opening area in the clearance hole 11, which in turn helps to ensure the structural strength of the vehicle body 10.
