Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a hinge device, a door system, and a vehicle. Background Technology

[0002] With the continuous development of the automotive industry and the constant improvement of vehicle body technology, new types of car doors are constantly being installed on various models. For example, side-opening doors, as a classic car opening and closing system, are the first choice for most models; scissor doors, on the other hand, are an unconventional car opening and closing system, which are more avant-garde, unique, and technologically advanced in appearance compared to side-opening doors.

[0003] Currently, all types of car doors are typically mounted independently to the vehicle body, resulting in a single opening method. However, each type of door has its own advantages and disadvantages. For example, side-opening doors are simple in design and easy to open, but difficult to open and close in narrow spaces; scissor doors have a cool opening style and require less space to open laterally, but pose safety risks. In the event of a car accident, scissor doors often cannot be opened due to vehicle deformation or rollover, hindering subsequent escape and rescue. Therefore, existing car doors cannot meet customers' needs for different door opening methods in various scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide a hinge device, a door system, and a vehicle, which aims to solve the problem that car doors cannot meet customers' needs for different opening methods in different scenarios.

[0076] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0077] The following is for reference. Figures 1-11 The hinge device 10, door system 100, and vehicle 1000 of the present invention are described in embodiments thereof.

[0078] refer to Figures 1-6 An embodiment of the first aspect of the present invention provides a hinge device 10 for a vehicle 1000. The hinge device 10 is connected to the vehicle body and adapted to movably connect a door 20. The hinge device 10 enables the vehicle 1000 to have a first mode and a second mode. In the first mode, the door 20 is movable relative to the hinge device 10; in the second mode, the relative position of the door 20 and the hinge device 10 is fixed, and the hinge device 10 can drive the door 20 to move relative to the vehicle body. By fixing the relative position of the door 20 and the hinge device 10, unnecessary swaying of the door 20 relative to the vehicle body is avoided in the second mode.

[0079] For example, in the first mode, the door 20 rotates relative to the hinge device 10 to switch the door 20 between an open and closed state relative to the vehicle body. In the second mode, the hinge device 10 rotates relative to the vehicle body to switch the door 20 between an open and closed state relative to the vehicle body.

[0080] Optionally, the hinge device 10 includes a second drive assembly 8. In the first mode, the second drive assembly 8 is in a working state and drives the door 20 to move relative to the hinge device 10. In the second mode, the second drive assembly 8 is in a locked state and has a certain restrictive effect on the door 20.

[0081] Optionally, the hinge device 10 also includes a first limiting structure 3, in which the first limiting structure 3 and the second drive assembly 8 in a locked state fix the relative position of the door 20 and the hinge device 10.

[0082] According to the hinge device 10 of the present invention, after the vehicle 1000 is equipped with the hinge device 10, the opening and closing mode of the door 20 can be freely switched between a first mode and a second mode, thereby meeting the needs of customers in different scenarios and taking into account the advantages of different types of doors 20, with good compatibility with the vehicle body environment; in addition, in the first mode, the door 20 can move relative to the hinge device 10, while in the second mode, the relative position of the door 20 and the hinge device 10 is fixed. The door 20 can adaptably cooperate with the hinge device 10 in different modes, without the need to set up a corresponding structure to control the cooperation relationship between the door 20 and the hinge device 10 to meet the movement requirements of the door 20 in different modes of the vehicle 1000, which helps to simplify the structure of the hinge device 10.

[0083] In some embodiments, in a first mode, the vehicle 1000 is a side-opening door; in a second mode, the vehicle 1000 is a scissor door. The first mode, being a side-opening door, provides good convenience for the vehicle 1000 with the hinge device 10 and reduces safety hazards, such as preventing subsequent escape and rescue from being hindered by the difficulty in opening the door 20 in the event of a car accident. The second mode, being a scissor door, allows the door 20 to be opened in confined spaces. By making the first mode a side-opening door and the second mode a scissor door, the hinge device 10 allows the vehicle 1000 to switch between the side-opening door and scissor door modes, and allows the vehicle 1000 equipped with the hinge device 10 to combine the advantages of both modes.

[0084] refer to Figures 1-6 In some embodiments, the hinge device 10 includes a connecting arm 2, which is connected to the vehicle body and adapted to movably connect to the door 20. In side-opening door mode, the door 20 can move relative to the connecting arm 2; in scissor door mode, the relative position of the door 20 and the connecting arm 2 is fixed, and the connecting arm 2 can drive the door 20 to move relative to the vehicle body. Optionally, the connecting arm 2 can be directly connected to the vehicle body or indirectly connected to the vehicle body. By providing the connecting arm 2, the stability and reliability of the door 20 can be improved.

[0085] refer to Figures 3-4 In some embodiments, the connecting arm 2 is provided with a first limiting structure 3, which is used to limit the relative position of the door 20 and the connecting arm 2 in the scissor door mode so as to fix the relative position of the door 20 and the connecting arm 2.

[0086] Optionally, the first limiting structure 3 fixes the relative position of the door and the connecting arm 2 by means of mechanical locking or magnetic locking. For example, the connecting arm 2 and the door 20 are locked by a buckle; for example, the connecting arm 2 and the door 20 are locked by magnetic attraction.

[0087] Optionally, the first limiting structure 3 is used to prevent the door 20 from moving relative to the vehicle body or to prevent the door 20 from rotating relative to the vehicle body.

[0088] In scissor door mode, by setting the first limiting structure 3, the door 20 and the connecting arm 2 are kept in a fixed relative position to ensure that the door 20 can move together with the connecting arm 2, and to prevent the door 20 from moving or shaking unnecessarily relative to the hinge device 10 during the opening process.

[0089] In some embodiments, in the side-opening door mode, the door 20 can rotate relative to the connecting arm 2 between a first position and a second position to switch between a closed state and an open state. When the door 20 is in the first position relative to the connecting arm 2, the door 20 is in the closed state; when the door 20 is in the second position relative to the connecting arm 2, the door 20 is in the open state. The door 20 switches between the closed and open states by rotating relative to the connecting arm 2, and the rotatable connection structure between the door 20 and the connecting arm 2 is simple.

[0090] For example, in the side-opening door mode, the door 20 rotates from the first position to the second position relative to the connecting arm 2 so that the door 20 changes from the closed state to the open state, and the door 20 rotates from the second position to the first position relative to the connecting arm 2 so that the door 20 changes from the open state to the closed state.

[0091] In some embodiments, in scissor door mode, the door 20 is in a first position relative to the connecting arm 2. In scissor door mode, by keeping the door 20 in the first position relative to the connecting arm 2, it is beneficial to reduce the space occupied by the door 20 on the side of the vehicle body.

[0092] refer to Figures 3-4 In some embodiments, in scissor door mode, the first limiting structure 3 is used to prevent the door 20 from rotating relative to the vehicle body, so as to avoid the door 20 swaying randomly relative to the vehicle body and so that the door 20 can be opened stably in scissor door mode. For example, the first limiting structure 3 is used to prevent the door 20 from rotating relative to the vehicle body under the action of gravity, or to prevent the door 20 from rotating due to external force.

[0093] refer to Figures 3-4 In some embodiments, in scissor door mode, the gravity of the door 20 has a first component force, which can drive the door 20 to rotate from a first position toward a direction away from a second position. The first limiting structure 3 is used to prevent the door 20 from rotating from the first position toward a direction away from the second position. By using the first limiting structure 3 to prevent the door 20 from rotating from the first position toward a direction away from the second position, it is beneficial to avoid the door 20 from swaying freely relative to the hinge device 10 under the action of gravity, which is beneficial to improving the stability of the hinge device 10 in the second mode.

[0094] refer to Figures 3-4 In some embodiments, the door 20 is provided with a second limiting structure 202. Along the direction of rotation from the second position to the first position, the first limiting structure 3 is located in front of the second limiting structure 202. When the door 20 is in the first position relative to the connecting arm 2, the first limiting structure 3 and the second limiting structure 202 abut against each other. By providing the second limiting structure 202 on the door 20, the first limiting structure 3 and the second limiting structure 202 can effectively limit the door 20. Furthermore, the structures of the first limiting structure 3 and the second limiting structure 202 are simple, and the cooperation between them is stable.

[0095] The first limiting structure 3 has a first limiting surface 31, and the second limiting structure 202 has a second limiting surface 2021. The first limiting surface 31 and the second limiting surface 2021 abut against each other to fix the relative position between the door 20 and the connecting arm 2. Both the first limiting surface 31 and the second limiting surface 2021 are planar, which helps to further improve the abutment stability of the first limiting structure 3 and the second limiting structure 202.

[0096] refer to Figures 5-6 In some embodiments, the hinge device 10 further includes a first drive assembly 6, which is tractively connected to the connecting arm 2. The connecting arm 2 is movably connected to the vehicle body. In scissor door mode, the first drive assembly 6 drives the connecting arm 2 to move relative to the vehicle body, thereby switching the door 20 between an open and closed state. Optionally, the first drive assembly 6 includes an electric strut, which drives the connecting arm 2 to move relative to the vehicle body through telescopic movement. The opening and closing of the door 20 can be automatically controlled. By setting the first drive assembly 6, the automation level and convenience of the hinge device 10 are improved. For example, the user only needs to press a button or use a remote control to open and close the door 20, without manual operation, greatly improving convenience.

[0097] refer to Figures 5-6 In some embodiments, in scissor door mode, the first drive assembly 6 drives the connecting arm 2 to rotate relative to the vehicle body, thereby switching the door 20 between an open state and a closed state. By driving the connecting arm 2 to rotate and switch the door 20 between an open state and a closed state, the overall mechanical structure of the hinge device 10 is simplified, which helps to reduce manufacturing costs and maintenance difficulty.

[0098] refer to Figures 5-8In some embodiments, the hinge device 10 further includes a rotating member 4, which is rotatably connected to the vehicle body. The connecting arm 2 includes a first connecting end 27 and a second connecting end 28. The first connecting end 27 is connected to the rotating member 4, and the second connecting end 28 is adapted to connect to the door 20. The first drive assembly 6 is used to drive the rotating member 4 to rotate relative to the vehicle body, thereby causing the connecting arm 2 and the door 20 to rotate relative to the vehicle body. By providing the rotating member 4, the distance between the first drive assembly 6 and the connecting arm 2 can be increased, which amplifies the torque provided by the first drive assembly 6. This means that a smaller driving force can generate a larger output torque, which can reduce the load on the first drive assembly 6 and extend its service life.

[0099] refer to Figures 5-8 In some embodiments, the rotating member 4 includes a first end and a second end disposed opposite to each other. A first drive assembly 6 is connected to the first end, and the second end is rotatably connected to the vehicle body. A first connecting end 27 is connected to the second end. By making the second end of the rotating member 4 rotatably connected to the vehicle body, the vehicle body provides a pivot point for the rotating member 4, so that the rotating member 4 rotates stably and transmits power stably to the connecting arm 2.

[0100] refer to Figures 5-8 In some embodiments, the first end of the rotating member 4 has a ball joint, and the first drive assembly 6 and the rotating member are connected by the ball joint.

[0101] In some embodiments, a reinforcing rib is provided on one side of the rotating member 4, which helps to enhance the structural rigidity and strength of the rotating member 4.

[0102] refer to Figures 5-8 In some embodiments, the hinge device 10 further includes a base 1, which is adapted to be connected to the vehicle body. The base 1 increases the connection points between the hinge device 10 and the vehicle body, enhancing the connection stability between them. The base 1 has a first pivot 42, and the second end of the rotating member 4 has a first bushing 41, which is fitted onto the first pivot 42. The first connecting end 27 is connected to the first bushing 41. By setting the first pivot 42 and the first bushing 41, their cooperation ensures the precise positioning of the rotating member 4 during rotation, reduces deviation and wobbling, improves the stability of the door 20 opening and closing, and also helps to reduce friction, making the movement of the rotating member 4 smoother and reducing noise and vibration.

[0103] refer to Figures 5-8In some embodiments, the first connecting end 27 is rotatably connected to the second end. When the first driving assembly 6 drives the rotating member 4 to rotate in the first direction to switch the door 20 from a closed state to an open state, the second connecting end 28 swings relative to the first connecting end 27 in a direction away from the base 1 along the axis of the first rotating shaft 42, thereby moving the door 20 to the outside of the vehicle body. This arrangement increases the opening range of the door 20, providing passengers with more space to enter and exit. The outward movement design also avoids interference between the door 20 and other parts of the vehicle body during opening, which is conducive to the smooth opening of the door 20.

[0104] refer to Figures 5-9 In some embodiments, the hinge device 10 further includes a support arm 5, which includes a third connecting end and a fourth connecting end. The third connecting end is rotatably connected to the base 1. The connecting arm 2 includes a connecting rod located between the first connecting end 27 and the second connecting end 28. The fourth connecting end is rotatably connected to the connecting rod.

[0105] When the first drive assembly 6 drives the rotating component 4 to rotate in the first direction, it can cause the fourth connecting end to swing away from the base 1 relative to the third connecting end along the axis of the first rotating shaft 42, thereby causing the second connecting end 28 to swing away from the base 1 relative to the first connecting end 27 along the axis of the first rotating shaft 42. By setting the support arm 5, the multi-point support design of the third and fourth connecting ends of the support arm 5 can improve the stability of the door 20 during opening and closing, reduce the shaking and noise of the door 20, and the outward swing of the fourth connecting end can make the force on the door 20 more even during opening and closing, reduce local stress concentration, and improve the overall durability of the system.

[0106] refer to Figures 5-9 In some embodiments, the base 1 is provided with two opposing first connecting lugs 11, the third connecting end of the support arm 5 is located between the two first connecting lugs 11, and the hinge device 10 includes a third rotating shaft 13, which passes through the two first connecting lugs 11 and the support arm 5.

[0107] refer to Figure 9 In some embodiments, the hinge device 10 further includes a fixed shaft 112, and a connecting fixed hole is formed on the first connecting lug 11 and the second rotating shaft 14. The fixed shaft 112 passes through the fixed hole to restrict the second rotating shaft 14 from rotating relative to the first connecting lug 11.

[0108] refer to Figure 9In some embodiments, the hinge device 10 further includes a third limiting structure 51. In scissor door mode, when the door 20 is in the open state, the third limiting structure 51 is used to limit the relative angle between the support arm 5 and the base 1. By setting the third limiting structure 51, a maximum opening angle can be set to prevent the door 20 from excessively rotating during opening. This can avoid unnecessary collisions with the door 20, such as preventing it from hitting other vehicles 1000. In addition, preventing excessive opening can also protect the connecting arm 2, the support arm 5, and other mechanical components from damage, extending the service life of the hinge device 10.

[0109] refer to Figure 9 In some embodiments, the third limiting structure 51 is located on the side of the support arm 5 away from the base 1, and the base 1 is provided with a fourth limiting structure 15. The fourth connecting end swings away from the base 1 in the first swing direction. Along the first swing direction, the third limiting structure 51 is located in front of the fourth limiting structure 15. In scissor door mode, when the door 20 is in the open state, the third limiting structure 51 and the fourth limiting structure 15 abut against each other. By providing the fourth limiting structure 15 that cooperates with the third limiting structure 51, the third limiting structure 51 can effectively play a limiting role, thereby effectively preventing the door 20 from being over-opened.

[0110] For example, the first drive assembly 6 is an electric strut. In the scissor door mode of the vehicle 1000, and during the opening of the door 20, the electric strut applies force to the first end of the rotating member 4 through a retraction action, causing the rotating member 4 to rotate in a first direction. The second end of the rotating member 4 can drive the second connecting end 28 to swing relative to the first connecting end 27 along the axis of the first rotating shaft 42 away from the base 1, thereby moving the door 20 to the outside of the vehicle body. At the same time, the connecting arm 2 also drives the fourth connecting end to swing relative to the third connecting end along the axis of the first rotating shaft 42 away from the base 1, further driving the second connecting end 28 to swing relative to the first connecting end 27 along the axis of the first rotating shaft 42 away from the base 1, thereby moving the door 20 to the outside of the vehicle body. Thus, the door 20 is switched from a closed state to an open state.

[0111] For example, the first drive assembly 6 is an electric strut. In the scissor door mode of the vehicle 1000, and during the closing process of the door 20, the electric strut applies force to the first end of the rotating member 4 through its extension action, causing the rotating member 4 to rotate in a second direction. The second end of the rotating member 4 can drive the second connecting end 28 to swing relative to the first connecting end 27 along the axis of the first rotating shaft 42 towards the base 1, thereby moving the door 20 towards the inside of the vehicle body. At the same time, the connecting arm 2 also drives the fourth connecting end to swing relative to the third connecting end along the axis of the first rotating shaft 42 towards the base 1, thereby further driving the second connecting end 28 to swing relative to the first connecting end 27 along the axis of the first rotating shaft 42 towards the base 1, thereby moving the door 20 towards the inside of the vehicle body. Thus, the door 20 switches from the open state to the closed state.

[0112] refer to Figures 5-9 In some embodiments, the first connecting end 27 is slidably connected to the first rotating shaft 42 along the axial direction of the first rotating shaft 42. When the first driving assembly 6 drives the rotating member 4 to rotate in the first direction, it can drive the first connecting end 27 to move towards the base 1 along the axial direction of the first rotating shaft 42. By making the first connecting end 27 slidable relative to the first rotating shaft 42, when the door 20 is opened in scissor door mode, the angle at which the connecting arm 2 drives the door 20 to swing away from the vehicle body can be further increased by moving the first connecting end 27 towards the base 1 along the axial direction of the first rotating shaft 42, thereby increasing the opening range of the door 20 and providing passengers with more space to enter and exit, making it easier to get on and off the vehicle.

[0113] refer to Figures 5-9 In some embodiments, a first stop 421 and a second stop 422 are respectively provided at both ends along the axial direction of the first rotating shaft 42. In scissor door mode, when the door 20 is in the open state, the first bushing 41 and the first stop 421 abut against each other. By providing the first stop 421 and the second stop 422, excessive sliding of the first bushing 41 relative to the first rotating shaft 42 is prevented. When the door 20 is in the open state, the first bushing 41 and the first stop 421 abut against each other, and the first stop 421 can provide support for the rotating member 4, thereby further improving the stability and reliability of the door 20 in the open state.

[0114] refer to Figures 5-9 In some embodiments, the second stop 422 is located away from the base 1 relative to the first stop 421, and the second stop 422 and the first rotating shaft 42 are detachably connected. By making the second stop 422 and the first rotating shaft 42 detachably connected, the second stop 422 can be prevented from obstructing the relevant installation operations during the assembly of the first bushing 41 to the first rotating shaft 42.

[0115] refer to Figures 5-9 In some embodiments, the second stop 422 and the first rotating shaft 42 are threadedly connected.

[0116] refer to Figures 5-7 In some embodiments, the hinge device 10 further includes a movable connector 43, which is movably connected to the base 1. A first rotating shaft 42 is disposed on the movable connector 43. When the first drive assembly 6 drives the rotating member 4 to move, it can drive the movable connector 43 to move relative to the base 1. By setting the movable connector 43 and placing the first rotating shaft 42 on the movable connector 43, the flexibility of the connection between the movable member and the vehicle body is improved. This allows the movable member to move relative to the vehicle body during the movement of the rotating member 4, facilitating multi-angle movement of the rotating member 4 and avoiding phenomena such as jamming or stuckness.

[0117] Optionally, the connection between the movable connector 43 and the base 1 is a cylindrical pair, and the movable connector 43 can rotate relative to the base 1, and the movable connector 43 can also slide relative to the base 1.

[0118] refer to Figures 5-7 In some embodiments, the hinge device 10 further includes a second pivot 14 disposed on the base 1, and a movable connector 43 is rotatably connected to the second pivot 14 and slidable along the extending direction of the second pivot 14. By making the movable connector 43 rotatable and slidable relative to the second pivot 14, the movable connector 43 provides the hinge device 10 with additional degrees of freedom of movement, thereby further improving the smoothness of the hinge device 10 during operation.

[0119] refer to Figures 5-7 In some embodiments, the base 1 is provided with a pair of opposing second connecting lugs 12, the movable connector 43 is located between the two second connecting lugs 12, and the second rotating shaft 14 passes through the two second connecting lugs 12. The movable connector 43 can slide along the second rotating shaft 14 between the two first connecting lugs 11.

[0120] For example, the first drive assembly 6 is an electric strut. In the scissor door mode of the vehicle 1000, and during the opening of the door 20, the electric strut applies force to the first end of the rotating member 4 through a retraction action. The electric strut drives the rotating member 4 to rotate in the first direction. The second bushing of the rotating member 4 rotates relative to the first rotating shaft 42 in the first direction and slides towards the base 1 along the axial direction of the first rotating shaft 42. At the same time, the first rotating shaft 42 drives the movable connecting member 43 to move relative to the base 1. Thus, the second end of the rotating member 4 can drive the second connecting end 28 to swing relative to the first connecting end 27 along the axial direction of the first rotating shaft 42 away from the base 1, so as to drive the door 20 to move to the outside of the vehicle body. At the same time, the connecting arm 2 also drives the fourth connecting end to swing relative to the third connecting end along the axial direction of the first rotating shaft 42 away from the base 1, so as to further drive the second connecting end 28 to swing relative to the first connecting end 27 along the axial direction of the first rotating shaft 42 away from the base 1, so as to drive the door 20 to move to the outside of the vehicle body. Through the cooperation of the above components, the door 20 is switched from the closed state to the open state.

[0121] For example, the first drive component 6 is an electric strut. In the scissor door mode of the vehicle 1000, and during the closing process of the door 20, the electric strut applies force to the first end of the rotating member 4 through its extension action. The electric strut drives the rotating member 4 to rotate in a second direction and slides towards the base 1 along the axis of the first rotating shaft 42. At the same time, the first rotating shaft 42 drives the movable connecting member 43 to move relative to the base 1. Thus, the second end of the rotating member 4 can drive the second connecting end 28 to swing relative to the first connecting end 27 along the axis of the first rotating shaft 42 towards the base 1, thereby moving the door 20 towards the inside of the vehicle body. Simultaneously, the connecting arm 2 also drives the fourth connecting end to swing relative to the third connecting end along the axis of the first rotating shaft 42 towards the base 1, further driving the second connecting end 28 to swing relative to the first connecting end 27 along the axis of the first rotating shaft 42 towards the base 1, thereby moving the door 20 towards the inside of the vehicle body. Through the cooperation of the above components, the door 20 is switched from the open state to the closed state.

[0122] refer to Figures 5-7In some optional embodiments, the hinge device 10 further includes a movable connector 43, which is rotatable relative to the base 1. The axis of the first rotating shaft 42 is a first axis, the axis of rotation of the support arm 5 relative to the base 1 is a second axis, the axis of rotation of the support arm 5 relative to the connecting arm 2 is a third axis, and the axis of rotation of the movable connector 43 relative to the base 1 is a fourth axis. Any two of the first, second, third, and fourth axes intersect. By making any two of the first, second, third, and fourth axes intersect, the intersecting axis design allows the various components to support and constrain each other during movement, reducing swaying and instability.

[0123] In some embodiments, the first axis, second axis, third axis, and fourth axis do not intersect at a single point. By ensuring that the first axis, second axis, third axis, and fourth axis do not intersect at a single point, the overall design of the hinge device 10 is more flexible, and the precision requirements of the hinge device 10 during the manufacturing process are lower, making it easier for the manufacturing machine to avoid the hinge device 10 failing to function properly due to manufacturing precision errors.

[0124] refer to Figure 5 In some embodiments, the hinge device 10 further includes a balancing mechanism 7, which includes a third end and a fourth end disposed opposite to each other. The third end is adapted to connect to the vehicle body, and the fourth end is connected to the connecting arm 2. The length of the balancing mechanism 7 from the third end to the fourth end is variable. Optionally, the balancing mechanism 7 is a gas spring or a balance bar. By providing the balancing mechanism 7, the balancing mechanism 7 assists the first drive assembly 6 in applying force, supports the weight of the door 20, and enhances the stability of the door 20 during movement.

[0125] In some embodiments, the balancing mechanism 7 and the connecting arm 2 are connected by a ball joint.

[0126] For example, in scissor door mode, the length of the balancing mechanism 7 changes as the connecting arm 2 moves.

[0127] refer to Figure 5 In some embodiments, the hinge device 10 further includes a second drive assembly 8 connected between the connecting arm 2 and the door 20. In the side-opening door mode, the second drive assembly 8 drives the door 20 to rotate relative to the connecting arm 2, switching between an open state and a closed state. By providing the second drive assembly 8, the automation level and convenience of the hinge device 10 are improved.

[0128] refer to Figure 5 , Figure 11Optionally, the second drive assembly 8 is an electric limiter. The hinge device 10 also includes a mounting bracket 26 and a mounting base 25. The mounting bracket 26 is located near the second connecting end 28 and is fixedly connected to the connecting arm 2. The mounting bracket 26 and the mounting base 25 are fixedly connected, and the mounting bracket 26 helps to enhance the installation stability of the second drive assembly 8. One end of the electric limiter is connected to the mounting base 25 via a revolute joint, and the other end is fixedly connected to the door 20, which provides electric power to drive the door 20 to rotate and can be suspended at any position.

[0129] For example, in the side-opening door mode, when the door 20 switches from the closed state to the open state, the electric limiter applies a force to the mounting seat 25 of the connecting arm 2 by extending, so that the door 20 rotates relative to the hinge device 10; when the door 20 switches from the open state to the closed state, the electric limiter applies a force to the mounting seat 25 of the connecting arm 2 by shortening, so that the door 20 rotates relative to the hinge device 10.

[0130] In scissor door mode, the second drive assembly 8 is locked, and the door 20 and the connecting arm 2 are in a rigid connection state. When the door 20 moves relative to the vehicle body along with the connecting arm 2, the door 20 is not easy to sway relative to the hinge device 10 from the first position toward the direction closer to the second position.

[0131] refer to Figures 5-10 In some embodiments, the hinge device 10 further includes a guide mechanism 9, which is fixedly connected between the base 1 and the connecting arm 2. In scissor door mode, the guide mechanism 9 allows the connecting arm 2 to rotate relative to the base 1 along a preset path and prevents the connecting arm 2 from moving relative to the base 1 along other paths outside the preset path. By setting the guide mechanism 9, the guide mechanism 9 can be used to limit and correct the movement trajectory of the door 20 in scissor door mode, prevent problems such as the door 20 sinking, and enhance the stability and dynamic holding capability of the door 20.

[0132] refer to Figure 10 In some embodiments, the guiding mechanism 9 includes a hole seat 91 and a slider 92. One of the hole seat 91 and the slider 92 is disposed on the base 1 and the other is disposed on the connecting arm 2. The hole seat 91 is provided with a sliding hole 911. The extension direction of the sliding hole 911 is consistent with the preset path. The slider 92 can be slidably accommodated in the sliding hole 911.

[0133] The hole seat 91 and the slider 92 are respectively located on the base 1 and the other is located on the connecting arm 2. This can include the following situations: for example, the hole seat 91 is located on the base 1 and the slider 92 is located on the connecting arm 2; or, for another example, the hole seat 91 is located on the connecting arm 2 and the slider 92 is located on the base 1.

[0134] Optionally, one of the hole seat 91 and the slider 92 is fixed to the base 1 and the other is fixed to the connecting arm 2.

[0135] By setting a mutually cooperating hole seat 91 and a sliding member 92, the sliding hole 911 of the hole seat 91 limits and guides the sliding member 92, thereby effectively limiting and guiding the rotation of the connecting arm 2 relative to the base 1.

[0136] refer to Figure 1 A second aspect of the present invention provides a door system 100, which includes the hinge device 10 described above.

[0137] According to the embodiment of the present invention, the door system 100, by providing the hinge device 10 described above, allows the door 20 to switch freely between a first mode and a second mode, thereby meeting the needs of customers in different scenarios and taking into account the advantages of different types of doors 20, and having good compatibility with the vehicle body environment.

[0138] refer to Figure 1 In some embodiments, the door system 100 also includes a door 20, and the connecting arm 2 of the hinge device 10 is connected to the door 20.

[0139] Optionally, the door 20 and the hinge device 10 are directly connected or indirectly connected.

[0140] Optionally, the second connecting end 28 of the connecting arm 2 is provided with a bearing 21, and the door 20 is provided with a connector 201. The connector 201 has a rotating arm 2011, and the rotating arm 2011 and the bearing 21 are rotatably connected so that the door 20 can rotate relative to the connecting arm 2.

[0141] Optionally, the connector 201 and the door 20 are detachably connected, and the door 20 is connected to the hinge device 10 via the connector 201. Optionally, the connector 201 and the door 20 are formed as one piece.

[0142] refer to Figure 5 In some embodiments, the hinge device 10 includes a second drive assembly 8 connected between the connecting arm 2 and the door 20. In scissor door mode, the second drive assembly 8 is locked to prevent the door 20 from moving relative to the connecting arm 2. The locked second drive assembly 8 prevents the door 20 from moving relative to the connecting arm, thus avoiding wobbling of the door 20 when opened in scissor door mode and improving the stability of the door 20 in scissor door mode.

[0143] In some embodiments, in the side-opening door mode, the second drive assembly is activated to drive the door to move relative to the connecting arm. The activated second drive assembly 8 can achieve high-precision position control of the door 20.

[0144] Optionally, the second drive assembly 8 is an electric limit switch. Optionally, the second drive assembly 8 includes a drive member and an output shaft. In the working state, the output shaft is retractable relative to the drive member, and in the locked state, the output shaft is fixed relative to the drive member.

[0145] For example, in the working state, the output shaft extends relative to the drive member to rotate the door 20 from the first position to the second position, and the door 20 switches from the closed state to the open state; the output shaft retracts relative to the drive member to rotate the door 20 from the second position to the first position, and the door 20 switches from the open state to the closed state.

[0146] For example, in the locked state, the door 20 and the connecting arm 2 are in a rigid connection state. When the door 20 moves relative to the vehicle body along with the connecting arm 2, the door 20 is not easy to sway relative to the hinge device 10 from the first position toward the direction closer to the second position.

[0147] refer to Figure 12 A third aspect of the present invention provides a vehicle 1000, which includes the hinge device 10 or door system 100 described above.

[0148] According to the vehicle 1000 of the present invention, by setting the hinge device 10 or the door system 100 described above, the opening and closing mode of the door 20 can be freely switched between the first mode and the second mode, so that the vehicle 1000 can meet the needs of customers in different scenarios, and take into account the advantages of different types of doors 20, and has good compatibility with the vehicle body environment.

[0149] In some embodiments, the vehicle 1000 has a control system for receiving instructions from a user to control the opening mode of the vehicle door 20 of the vehicle 1000.

[0150] Optionally, the control system may include sensors for monitoring the position and status of the door 20 to ensure safety and accuracy when switching modes.

[0151] Optionally, the control system also includes a user interface that provides a simple operating interface, allowing the driver or passenger to easily select whether the vehicle 1000 opens the door 20 in a first or second mode.

[0152] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
