In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0055] In some embodiments of the present application, a vehicle 200 is provided, referring to Figure 1 to Figure 7The vehicle 200 includes a vehicle body 210, a first door 220 and a second door 230. The vehicle 200 may adopt a double-door design without a B-pillar, specifically, the first door 220 and the second door 230 are located on the same side of the vehicle body 210, and the first door 220 and the vehicle body 210 are rotatably connected through the driving device 100, that is, the side of the first door 220 away from the second door 230 is rotatably connected to the vehicle body 210 through the driving device 100, and the side of the second door 230 away from the first door 220 is rotatably connected to the vehicle body 210, that is, the first door 220 and the second door 230 are double-door structures. The first door 220 may be arranged near the rear of the vehicle, that is, the first door 220 is the rear door of the vehicle. Correspondingly, the second door 230 may be arranged near the front of the vehicle, that is, the second door 230 is the front door of the vehicle.

[0056] Of course, in other embodiments of the present application, the second door 230 and the vehicle body 210 may also be rotatably connected via the driving device 100. Furthermore, the first door 220 may be arranged near the front of the vehicle 200, that is, the first door 220 is the front door of the vehicle 200, and the second door 230 may be arranged near the rear of the vehicle 200, that is, the second door 230 is the rear door of the vehicle 200. In addition, the vehicle 200 of the present application is not limited to a double-door design without a B-pillar. For example, the side of the first door 220 near the second door 230 may be rotatably connected to the vehicle body 210, and the side of the second door 230 away from the first door 220 may be rotatably connected to the vehicle body 210, and the like, which is not limited here.

[0057] Among them, refer to Figure 1 to Figure 7 as well as Fig.10 The first door 220 includes a movable side 221 and a connecting side 222 that are relatively arranged along its length direction X. The movable side 221 is a side of the first door 220 close to the second door 230, and the connecting side 222 is a side of the first door 220 away from the second door 230.

[0058] In some embodiments of the present application, a driving device 100 is provided, referring to Figure 1-2 , Figures 4 to 6 as well as Figure 8 to Figure 11 The driving device 100 includes a hinge assembly 10 and a driving assembly 20 .

[0059] Reference Figure 2 , Figure 4 to Figure 7 as well as Figures 9 to 11 The hinge assembly 10 includes a rotating arm 11, and the rotating arm 11 includes a first end 111 and a second end 112 disposed opposite to each other. Figure 2 , Figure 4 to Figure 7 as well as Figures 9 to 11The first end 111 is used for rotationally connecting to the body 210 of the vehicle 200 , and the second end 112 is used for rotationally connecting to the first door 220 of the vehicle 200 . Specifically, the second end 112 is used for rotationally connecting to the connecting side 222 of the first door 220 .

[0060] Reference Figure 1-2 , Figures 4 to 6 as well as Figure 12-13 The driving assembly 20 includes a driving arm 21, and the driving arm 21 includes a connecting end 211 and a driving end 212 that are arranged opposite to each other. Figure 2 , Figures 4 to 6 The connecting end 211 is used for rotationally connecting with the vehicle body 210 , and the driving end 212 is used for connecting with the first vehicle door 220 .

[0061] The rotating arm 11 can rotate about the first end 111 by a first angle α; the driving end 212 can move along the length direction X of the first door 220 to drive the first door 220 to rotate about the second end 112 by a second angle β.

[0062] The doors of existing vehicles are mostly connected to the vehicle body by a four-bar linkage. Specifically, a fixed arm in the four-bar linkage is installed on the vehicle body, a movable arm in the four-bar linkage is connected to the door, and the movable arm is rotatably connected to the fixed arm. The movable arm rotates relative to the fixed arm to drive the door to rotate relative to the vehicle body. However, the movable arm in the four-bar linkage of existing vehicles has a small rotation range, resulting in a small opening angle of the door, which is not conducive to passengers getting on and off the vehicle and carrying items such as luggage.

[0063] The driving device 100 provided in the embodiment of the present application is provided with a hinge assembly 10 and a driving assembly 20 to realize a rotational connection between a body 210 of the vehicle 200 and a first door 220. Specifically, the hinge assembly 10 includes a rotating arm 11, and the rotating arm 11 includes a first end 111 and a second end 112 arranged opposite to each other. The first end 111 of the rotating arm 11 is used for rotational connection with the body 210 of the vehicle 200, and the second end 112 is used for rotational connection with the first door 220. The driving assembly 20 includes a driving arm 21, and the driving arm 21 includes a connecting end 211 and a driving end 212 arranged opposite to each other. The connecting end 211 is used for rotational connection with the body 210, and the driving end 212 is used for connection with the first door 220.

[0064] The rotating arm 11 can rotate by a first angle α with the first end 111 as the axis, so that the first door 220 switches between the closed state S1 and the first open state S2. The driving end 212 of the driving arm 21 can move along the length direction X of the first door 220 to drive the first door 220 to rotate by a second angle β with the second end 112 of the rotating arm 11 as the axis, so that the first door 220 switches between the second open state S3 and the first open state S2. Thus, the rotating arm 11 in the hinge assembly 10 and the driving arm 21 in the driving assembly 20 form a dual driving structure for the first door 220, so as to drive the first door 220 to form a two-stage motion trajectory, effectively increasing the opening range of the first door 220 and improving the convenience of use.

[0065] Specifically, in the opening stage of the first door 220, the rotating arm 11 is firstly rotated in a positive direction by a first angle α with the first end 111 as an axis, so that the first door 220 changes from the closed state S1 (such as Figure 1 and Figure 2 As shown) moves to the first open state S2 (as shown Figure 3 and Figure 4 As shown), that is, the first door 220 moves from the door installation opening position embedded in the vehicle body 210 to the door installation opening position separated from the vehicle body 210, and then moves along the length direction X of the first door 220 through the driving end 212 of the driving arm 21. Specifically, the driving end 212 moves along the length direction X of the first door 220 from the movable side 221 to the direction close to the connecting side 222, and then through the rotation connection between the connecting end 211 and the vehicle body 210, the first door 220 is driven to rotate positively by the second angle β around the second end 112 as the axis, so that the first door 220 changes from the first open state S2 (as shown in FIG. Figure 3 and Figure 4 As shown) moves to the second open state S3 (as shown Figure 5 and Figure 6 As shown), a two-stage opening structure of the first door 220 is realized, namely a first opening state and a second opening state, thereby realizing a large-angle opening structure of the first door 220. Compared with the vehicle in which the door is driven to open by a conventional four-link structure, the driving device 100 provided in the embodiment of the present application can effectively increase the opening range of the first door, thereby improving the convenience for passengers to get on and off the vehicle and to carry items such as luggage.

[0066] On the contrary, in the closing stage of the first door 220, the driving end 212 of the driving arm 21 first moves along the length direction X of the first door 220. Specifically, the driving end 212 moves along the length direction X of the first door 220 from the connecting side 222 to the direction close to the movable side 221, and then the first door 220 is driven to rotate in the opposite direction by a second angle β around the second end 112 as an axis through the rotation connection between the connecting end 211 and the vehicle body 210, so that the first door 220 moves from the second open state S3 to the first open state S2, thereby realizing the first door 220 being opened. 20 switches between the second open state S3 and the first open state S2, and then the rotating arm 11 rotates in the opposite direction by a first angle α around the first end 111 as the axis, so that the first door 220 moves from the first open state S2 to the closed state S1, thereby realizing the switching of the first door 220 between the first open state S2 and the closed state S1, that is, the first door 220 moves from the door mounting opening position detached from the vehicle body 210 to the door mounting opening position embedded in the vehicle body 210, so as to close the first door 220 and ensure the smooth closing of the first door 220.

[0067] Moreover, the two-stage opening structure of the first door 220, especially the movement of the first door 220 from the closed state S1 to the first open state S2, can effectively avoid the interference between the first door 220 and the second door 230 during the opening process, and ensure that the first door 220 can be opened smoothly. Figure 8 In the embodiment shown, it can be seen that the motion envelopes of the first door 220 and the second door 230 do not overlap, and the driving device 100 provided in the embodiment of the present application avoids the problem of interference between the first door 220 and the second door 230 during the opening and closing process. The driving device 100 provided in the embodiment of the present application can adapt to the requirements of various vehicle models for a B-pillar-free double-door design.

[0068] In some embodiments, reference Figure 4, the first door 220 moves from the closed state S1 to the first open state S2, and the movement trajectory of the first door 220 is the first trajectory A1, that is, the movement trajectory of the movable side 221 of the first door 220 forms the first trajectory A1, and the shape of the first trajectory A1 is an arc. Specifically, during the movement of the first door 220 from the closed state S1 to the first open state S2, along the first trajectory A1, the movable side 221 of the first door 220 moves away from the second door 230, thereby preventing the first door 220 from colliding with the second door 230 during the opening process. Interference occurs, ensuring the smooth opening of the first door 220; conversely, the first door 220 moves from the first open state S2 to the closed state S1, and the movement trajectory of the first door 220 is also the first trajectory A1. Specifically, during the process of the first door 220 moving from the first open state S2 to the closed state S1, along the first trajectory A1, the movable side 221 of the first door 220 moves toward the direction close to the second door 230, thereby avoiding interference between the first door 220 and the second door 230 during the closing process, thereby ensuring the smooth closing of the first door 220.

[0069] In some embodiments, reference Figure 6 , the first door 220 moves from the first open state S2 to the second open state S3, and the movement trajectory of the first door 220 is the second trajectory A2, that is, the movement trajectory of the active side 221 of the first door 220 forms the second trajectory A2, and the shape of the second trajectory A2 is an arc. Specifically, in the process of the first door 220 moving from the first open state S2 to the second open state S3, along the second trajectory A2, the active side 221 of the first door 220 further moves away from the second door 230, and the length of the second trajectory A2 is greater than the length of the first trajectory A1, thereby realizing a large-angle opening of the first door 220 and increasing the opening amplitude of the first door 220.

[0070] In some embodiments, reference Figure 2 , Figure 4 , Figure 6 as well as Figure 8 The hinge assembly 10 further includes a first mounting member 12 and a second mounting member 13, referring to Figure 2 , Figure 4 as well as Figure 6The first mounting member 12 is used to be mounted on the vehicle body 210, and the rotating arm 11 is rotatably connected to the first mounting member 12 through the first end 111. The second mounting member 13 is used to be mounted on the first door 220, and the first door 220 is rotatably connected to the second end 112 through the second mounting member 13. The provision of the first mounting member 12 can ensure the connection stability between the rotating arm 11 and the vehicle body 210, and further ensure the stability of the rotating arm 11 rotating around the first end 111 as the axis. The provision of the second mounting member 13 can ensure the connection stability between the rotating arm 11 and the first door 220, and further ensure the stability of the first door 220 rotating around the second end 112 as the axis.

[0071] In some embodiments, reference Figure 4 , Figure 6 as well as Figure 9-10 The first mounting member 12 is provided with a first protruding portion 121 protruding from one end adjacent to the first end 111. Figure 9-10 , a second protrusion 1111 is protruded from the first end 111, and when the first door 220 moves from the closed state S1 to the first open state S2, the first protrusion 121 abuts against the second protrusion 1111 to limit the rotation of the rotating arm 11. The matching design of the first protrusion 121 and the second protrusion 1111 allows the first protrusion 121 to abut against the second protrusion 1111 when the first door 220 moves from the closed state S1 to the first open state S2, so that the rotating arm 11 does not continue to rotate about the first end 111 after rotating about the first end 111 as the axis by the first angle α, that is, when the first door 220 continues to move from the first open state S2 to the second open state S3, the rotating arm 11 remains stationary, ensuring that the first door 220 moves from the first open state S2 to the second open state S3 smoothly and smoothly.

[0072] In some embodiments, reference Figure 2 , Figure 4 , Figure 6 as well as Figures 9 to 11 The first mounting member 12 includes a first mounting seat 122 and a first connecting arm 123 connected to each other. Figure 2 , Figure 4 as well as Figure 6 The first mounting member 12 is mounted on the vehicle body 210 through the first mounting seat 122. Specifically, the first mounting seat 122 is detachably mounted on the vehicle body 210 through bolts. One end of the first connecting arm 123 is rotatably connected to the first end 111 of the rotating arm 11, and the other end is fixedly connected to the first mounting seat 122 to ensure the installation stability between the first mounting seat 122 and the vehicle body 210, thereby ensuring the connection stability between the rotating arm 11 and the vehicle body 210. Figure 4 , Figure 6 as well as Figures 9 to 11The first protrusion 121 is protrudingly disposed at an end of the first connecting arm 123 adjacent to the first end 111 .

[0073] In some embodiments, reference Figure 2 , Figure 4 , Figure 6 as well as Figures 9 to 11 The second mounting member 13 is provided with a third protrusion 131 protruding from one end adjacent to the second end 112. Figure 2 , Figure 4 as well as Figure 6 When the first door 220 is in the closed state S1 and the first door 220 is in the first open state S2, there is a gap between the third protrusion 131 and the second end 112 of the rotating arm 11, that is, the third protrusion 131 does not contact the second end 112. Figure 6 and Fig. 9 , Fig.11 , Figure 6 It is a schematic diagram showing the structure of the first door 220 moving to the second open state S3. Fig. 9 and Fig.11 The figure shows the structural state of the rotating arm 11 when the first door 220 moves to the second opening state S3. When the first door 220 moves to the second opening state, the third protrusion 131 abuts against the second end 112 to limit the rotation of the first door 220. The third protrusion 131 can block and limit the rotation of the first door 220 when the first door 220 rotates to the second opening state S3, thereby preventing the first door 220 from opening too much, avoiding the first door 220 from colliding with the vehicle body 210 due to the first door 220 opening too much and causing damage, thereby ensuring the opening safety of the first door 220 and ensuring the service life and use safety of the vehicle 200.

[0074] In some embodiments, reference Figure 2 , Figure 4 , Figure 6 as well as Figures 9 to 11 The second mounting member 13 includes a second mounting seat 132 and a second connecting arm 133. The second mounting member 13 is mounted on the first door 220 through the second mounting seat 132. Specifically, the second mounting seat 132 is detachably mounted on the first door 220 through bolts. One end of the second connecting arm 133 is fixedly connected to the second mounting seat 132, and the other end is rotatably connected to the second end 112 of the rotating arm 11 to ensure the installation stability between the second mounting seat 132 and the first door 220, thereby ensuring the connection stability between the rotating arm 11 and the first door 220. The third protrusion 131 is protrudingly arranged at one end of the second connecting arm 133 adjacent to the second end 112.

[0075] In some embodiments, reference Fig. 9, the third protrusion 131 can rotate to a third angle θ, satisfying: β=θ. Specifically, the second mounting seat 132 is mounted on the first door 220, and the second connecting arm 133 is fixedly connected to the second mounting seat 132, so that during the process of the first door 220 rotating from the first open state S2 to the second open state S3, the first door 220 can drive the second connecting arm 133 and the third protrusion 131 to rotate synchronously through the second mounting seat 132, thereby making the rotation angle β of the first door 220 the same as the rotation angle θ of the third protrusion 131, so that when the first door 220 rotates and moves to the second open state S3, the third protrusion 131 can abut against the second end 112 of the rotating arm 11 to prevent the first door 220 from continuing to rotate with the second end 112 as the axis, thereby ensuring the opening safety of the first door 220 and ensuring the service life and use safety of the vehicle 200.

[0076] In some embodiments, a rotating drive member (not shown in the figure) for driving the rotating arm 11 to rotate about the first end 111 as an axis may be provided on the vehicle body 210, thereby automatically driving the rotating arm 11 to drive the first door 220 to switch between the closed state S1 and the first open state S2. The rotating drive member may be a cylinder or a telescopic motor. In some other implementations, the first door 220 may be manually driven by the passengers to switch between the closed state S1 and the first open state S2, that is, the rotating arm 11 is driven to rotate about the first end 111 as an axis by the first door 220. Specifically, the passengers drive the first door 220 to switch between the closed state S1 and the first open state S2 through a handle (not shown in the figure) provided at one end of the first door 220 adjacent to the second door 230 along its length direction X.

[0077] In some embodiments, reference Figure 2 , Figure 4 , Figure 6 as well as Figures 9 to 11 The hinge assembly 10 also includes a first rotating shaft 14 and a second rotating shaft 15. The first rotating shaft 14 is inserted between the first end 111 and the first connecting arm 123, so that the rotating arm 11 can rotate a first angle α around the first rotating shaft 14 to ensure the rotational stability of the rotating arm 11. The second rotating shaft 15 is inserted between the second end 112 and the second connecting arm 133, so that the first vehicle door 220 can rotate a second angle β around the second rotating shaft 15 through the second mounting member 13 to ensure the rotational stability of the first vehicle door 220.

[0078] In some embodiments, reference Figure 2 , Figure 4 , Figure 6 as well as Figure 12-13The driving assembly 20 also includes a third mounting member 22, which is used to be installed on the vehicle body 210. The connecting end 211 of the driving arm 21 is rotatably connected to the third mounting member 22. The setting of the third mounting member 22 can ensure the connection stability between the driving arm 21 and the vehicle body 210, thereby ensuring the stability of the driving arm 21 driving the first door 220 to rotate around the second end 112 as the axis.

[0079] In some embodiments, reference Fig.13 The driving assembly 20 further includes a driving member 23, which is used to be installed on the first door 220. The driving end 212 of the driving arm 21 is connected to the driving member 23, and the driving member 23 can drive the driving end 212 to move along the length direction X of the first door 220. The driving member 23 is arranged to drive the driving end 212 to move along the length direction X of the first door 220. Combined with the structural design that the connecting end 211 of the driving arm 21 is rotatably connected to the third mounting member 22, the driving end 212 can generate a force through the driving arm 21 during the movement, and the driving arm 21 then generates a reaction force on the first door 220 through the driving end 212, so as to drive the first door 220 to rotate around the second end 112 as the axis, thereby ensuring the rotation stability of the first door 220, and improving the automatic degree of opening and closing of the first door 220, saving the passenger's effort in opening and closing the first door 220.

[0080] In some embodiments, the third mounting member 22 is a ball head to ensure the stability of the rotational connection between the connecting end 211 of the driving arm 21 and the third mounting member 22. In other implementations, the third mounting member 22 may adopt other connection structures, and it is only necessary to ensure that the connecting end 211 of the driving arm 21 and the third mounting member 22 are rotationally connected.

[0081] In some embodiments, the driving member 23 is a telescopic motor or a cylinder, and the driving member 23 is connected to the driving end 212 of the driving arm 21 to drive the driving end 212 to move along the length direction X of the first door 220 .

[0082] In some embodiments, reference Fig.13The driving assembly 20 further includes: a transmission rod 24 and a sliding member 25. The transmission rod 24 is used to be installed on the first door 220 and extends along the length direction X of the first door 220. One end of the transmission rod 24 is connected to the driving member 23. The sliding member 25 is arranged on the transmission rod 24. The driving end 212 of the driving arm 21 is connected to the sliding member 25. The driving member 23 can drive the transmission rod 24 to drive the sliding member 25 to move along the length direction X of the first door 220. The sliding member 25 drives the driving end 212 to move along the length direction X of the first door 220, thereby driving the first door 220 to switch between the first opening state S2 and the second opening state S3. The matching design of the transmission rod 24 and the sliding member 25 can ensure the stability of the driving end 212 moving along the length direction X of the first door 220, thereby ensuring the stability and smoothness of the switching of the first door 220 between the first opening state S2 and the second opening state S3.

[0083] In some embodiments, the driving member 23 is a rotating motor, specifically, the driving member 23 is a screw motor, the transmission rod 24 is a screw, the sliding member 25 is a slider, the sliding member 25 is sleeved on the transmission rod 24, and the driving member 23 drives the transmission rod 24 to rotate, so as to drive the sliding member 25 to move along the length direction X of the first door 220, thereby driving the driving end 212 to move along the length direction X of the first door 220.

[0084] In some embodiments, reference Fig.14 The driving assembly 20 further includes a limit member 26, which includes an elastic portion 261 and a stopper 262, wherein the elastic portion 261 and the stopper 262 are sequentially connected, and the stopper 262 is mounted on the first door 220 through the elastic portion 261, and an end of the stopper 262 that is away from the elastic portion 261 faces the transmission rod 24, referring to Fig.11 The sliding member 25 is provided with a groove 251, wherein the sliding member 25 moves along the length direction X of the first door 220, the stopper 262 can be inserted into the groove 251 to limit the movement of the sliding member 25, and the driving member 23 can drive the transmission rod 24 to drive the sliding member 25 to separate from the stopper 262. The matching design of the elastic part 261 and the stopper 262 in the limiting member 26 can keep the sliding member 25 in a specific position during the movement of the sliding member 25 along the length direction X of the first door 220, so that the first door 220 is kept in a specific state, ensuring the stability and smoothness of the opening or closing of the first door 220.

[0085] In some embodiments, along the length direction X of the first door 220, the stopper 26 is disposed at one end of the first door 220 adjacent to the movable side 221. When the first door 220 moves to the closed state S1, the stopper 262 can be inserted into the groove 251, so that the first door 220 remains in the closed state S1. When the first door 220 is closed, that is, the first door 220 moves from the first open state S2 to the closed state S1, the driving member 23 drives the transmission rod 24 to rotate to drive the sliding member 25 to approach the movable side 221 along the length direction X of the first door 220. The sliding member 25 pushes the stopper 262, so that the stopper 262 shrinks along the extension direction of the elastic part 261. As the sliding member 25 continues to approach the movable side 221, the stopper 262 is inserted into the groove 251 under the elastic deformation of the elastic part 261, so that the sliding member 25 remains at one end adjacent to the movable side 221, thereby maintaining the first door 220 in the closed state S1.

[0086] When the first door 220 is opened, the driving member 23 drives the transmission rod 24 to rotate to drive the sliding member 25 to move away from the movable side 221 along the length direction X of the first door 220, and the sliding member 25 pushes the stop portion 262, so that the stop portion 262 contracts along the extension and contraction direction of the elastic portion 261. As the sliding member 25 continues to move away from the movable side 221, the sliding member 25 separates from the stop portion 262, so that the first door 220 can move to the first open state S2.

[0087] In some embodiments, along the length direction X of the first door 220, the stopper 26 is disposed at one end of the first door 220 adjacent to the connection side 222. When the first door 220 moves to the second open state S3, the stopper 262 can be inserted into the groove 251, so that the first door 220 remains in the second open state S3. When the first door 220 moves from the first open state S2 to the second open state S3, the driving member 23 can drive the transmission rod 24 to rotate to drive the sliding member 25 to approach the connection side 222 along the length direction X of the first door 220. The sliding member 25 pushes the stopper 262, so that the stopper 262 shrinks along the extension direction of the elastic member 261. As the sliding member 25 approaches the connection side 222, the stopper 262 is inserted into the groove 251 under the elastic deformation of the elastic member 261, so that the sliding member 25 remains at one end adjacent to the connection side 222, thereby enabling the first door 220 to remain in the second open state S3.

[0088] When the first door 220 is closed, the driving member 23 drives the transmission rod 24 to rotate to drive the sliding member 25 to move away from the connecting side 222 along the length direction X of the first door 220, and the sliding member 25 pushes the stop portion 262, so that the stop portion 262 contracts along the extension and contraction direction of the elastic portion 261. As the sliding member 25 continues to move away from the connecting side 222, the sliding member 25 separates from the stop portion 262, so that the first door 220 can move from the second open state S3 to the first open state S2.

[0089] In some embodiments, along the length direction X of the first door 220, the stopper 26 is disposed between the connection side 222 and the movable side 221. When the first door 220 moves to the first open state S2, the stopper 262 can be inserted into the groove 251, so that the first door 220 remains in the first open state S2. When the first door 220 moves from the second open state S3 to the first open state S2, the driving member 23 drives the transmission rod 24 to rotate to drive the sliding member 25 to move away from the connection side 222 along the length direction X of the first door 220. The sliding member 25 pushes the stopper 262, so that the stopper 262 contracts along the extension direction of the elastic member 261. As the first door 220 moves to the first open state S2, the stopper 262 is inserted into the groove 251 under the action of the elastic deformation of the elastic member 261, so that the first door 220 remains in the first open state S2. Similarly, when the first door 220 moves from the closed state S1 to the first open state S2, the driving member 23 drives the transmission rod 24 to rotate to drive the sliding member 25 to move away from the movable side 221 along the length direction X of the first door 220, and the sliding member 25 pushes the stop portion 262, so that the stop portion 262 contracts along the extension and contraction direction of the elastic portion 261. As the first door 220 moves to the first open state S2, the stop portion 262 is inserted into the groove 251 under the action of the elastic deformation of the elastic portion 261, so that the first door 220 remains in the first open state S2.

[0090] In some embodiments, reference Figure 2 , Figure 4 , Figure 6 as well as Figure 12 to Figure 14 The driving assembly 20 also includes a receiving member 27, which extends along the length direction X of the first door 220. The receiving member 27 is arranged on the side of the first door 220 facing the body 210. The receiving member 27 has a receiving groove on the side facing the body 210. The driving member 23, the transmission rod 24, the sliding member 25 and the limiting member 26 are all arranged in the receiving groove of the receiving member 27, and the end of the elastic portion 261 away from the stop portion 262 abuts against the bottom of the receiving groove.

[0091] In some embodiments, the first angle α satisfies 45°≤α≤51°. Specifically, the value of α can be any value among 45°, 46°, 47°, 48°, 49°, 50°, 51°, or any value in a range of values ​​consisting of any two values. When the value of α is within the above range, it can ensure that the first door 220 switches smoothly and stably between the closed state S1 and the first open state S2, and the drive device 100 can be adapted to a variety of vehicle models, such as sedans, SUVs (i.e., sport utility vehicles), etc.

[0092] In some embodiments, the first angle α is 48°.

[0093] In some embodiments, the second angle β satisfies 70°≤β≤80°. Specifically, the value of β can be any value among 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 80°, or any value in a range of values ​​consisting of any two values. When the value of β is within the above range, the first door 220 can be smoothly and stably switched between the first open state S2 and the second open state S3, and the drive device 100 can be adapted to a variety of vehicle models, such as sedans, SUVs (i.e., sport utility vehicles), etc.

[0094] In some embodiments, the second angle β is 75°.

[0095] In some embodiments, α<β, thereby forming a large-angle opening structure of the first door 220 .

[0096] In some embodiments, reference Figure 6 The first door 220 moves from the first open state S2 to the second open state S3, and the movement trajectory of the first door 220 is the second trajectory A2, that is, the movement trajectory of the active side 221 of the first door 220 forms the second trajectory A2, and the length of the second trajectory A2 is greater than the length of the first trajectory A1, so that the second angle β is greater than the first angle α, thereby realizing a large-angle opening of the first door 220.

[0097] In some embodiments, reference Figure 6, the distance that the driving end 212 moves along the length direction X of the first door 220 is Lmm, which satisfies: 350mm≤L≤450mm. Specifically, the value of L can be any value among 350mm, 360mm, 370mm, 380mm, 390mm, 400mm, 410mm, 420mm, 430mm, 440mm, 450mm, or any value in the range of values ​​consisting of any two values. The value of L is positively correlated with the value of β. When the value of L is within the above range, the first door 220 can be smoothly and stably switched between the first opening state S2 and the second opening state S3.

[0098] In some embodiments, when the first door 220 switches between the closed state S1 and the first open state S2, the driving arm 21 can rotate 18° to 28° with the connecting end 211 as the axis. Specifically, the driving arm 21 can rotate with the connecting end 211 as the axis by any value of 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28° or any value in the range of values ​​composed of any two values. When the angle at which the driving arm 21 rotates with the connecting end 211 as the axis is within the above range, the first door 220 switches between the closed state S1 and the first open state S2, and the driving arm 21 can move with the first door 220, thereby ensuring the smoothness of the switching of the first door 220 between the closed state S1 and the first open state S2, and avoiding the driving arm 21 from interfering with the first door 220.

[0099] In some embodiments, when the first door 220 switches between the closed state S1 and the first open state S2 , the driving arm 21 can rotate 23° around the connecting end 211 .

[0100] In some embodiments, when the first door 220 switches between the first open state S2 and the second open state S3, the driving arm 21 can rotate 70° to 80° with the connecting end 211 as the axis. Specifically, the driving arm 21 can rotate with the connecting end 211 as the axis at an angle of 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 80° or any value in a range of values ​​consisting of any two values. When the angle at which the driving arm 21 rotates with the connecting end 211 as the axis is within the above range, the smoothness of the switching of the first door 220 between the first open state S2 and the second open state S3 can be ensured, thereby ensuring the smoothness of the opening or closing of the first door 220.

[0101] In some embodiments, reference Figure 5The rotating arm 11 and the driving arm 21 are spaced apart along the height direction Z of the vehicle body 210. Specifically, the first end 111 of the rotating arm 11 is connected to the middle section of the height of the vehicle body 210, and the connecting end 211 of the driving arm 21 is connected to the threshold position of the vehicle body 210. Accordingly, the accommodating member 27 is arranged at one end of the first door 220 adjacent to the threshold position along the height direction Z of the first door 220, so that the driving device 100 forms a spatial four-bar linkage between the vehicle body 210 and the first door 220, thereby ensuring the connection stability of the driving device 100 with the vehicle body 210 and the first door 220, saving the force required for opening or closing the first door 220, and ensuring the stability and smoothness of opening or closing the first door 220.

[0102] In some embodiments, the first mounting member 12 is mounted on the C-pillar structure 2101 of the vehicle body 210, thereby ensuring the connection stability between the rotating arm 11 and the vehicle body 210. It should be noted that, for the example in which the first door 220 is the rear door of the vehicle 200, the installation space of the first mounting member 12 is located in the C-pillar structure 2101 of the vehicle body 210. The first mounting member 12 and at least part of the rotating arm 11 are located in the C-pillar structure 2101 of the vehicle body 210, which can not only enhance the structural strength of the vehicle body 210 and improve the safety performance of the overall structure, but also optimize the structural layout of the hinge assembly 10, which is conducive to improving space utilization. In addition, the structure of the hinge assembly 10 is compact, which is conducive to the installation design of the hinge assembly 10 embedded in the C-pillar structure 2101, while saving space in the vehicle body 210.

[0103] In some embodiments, reference Figure 7 The interior of the vehicle body 210 has an installation space (not shown in the figure). For the example in which the first door 220 is the rear door of the vehicle 200, the installation space is located in the C-pillar structure 2101 of the vehicle body 210. The vehicle body 210 is also provided with an avoidance hole 2102 connected to the installation space. The first mounting member 12 in the hinge assembly 10 is installed in the installation space. The number of the rotating arms 11 is two, which are arranged at intervals along the height direction Z of the vehicle body 210. The rotating arms 11 can be movably inserted into the avoidance hole 2102, so that the first end 111 of the rotating arm 11 can be rotatably connected to the first connecting arm 123 of the first mounting member 12. The first connecting arm 123 and the first end 111 of the rotating arm 11 are detachably arranged.

[0104] In addition, the hinge assembly 10 is entirely forged, which helps to ensure the structural stability and safety of the hinge assembly 10 and meet strict automotive industry standards.

[0105] In some embodiments, reference Figure 3 and Figure 4, the first door 220 moves to the first open state S2, and the length direction X of the first door 220 is parallel or approximately parallel to the length direction X of the vehicle body 210.

[0106] Of course, in other embodiments of the present application, the second door 230 and the vehicle body 210 may also be rotatably connected via the driving device 100. Furthermore, the first door 220 may be arranged near the front of the vehicle, i.e., the first door 220 is the front door of the vehicle 200, and the second door 230 may be arranged near the rear of the vehicle 200, i.e., the second door 230 is the rear door of the vehicle 200. In addition, the vehicle 200 provided in the embodiment of the present application is not limited to a double-door design without a B-pillar. For example, the side of the first door 220 near the second door 230 may be rotatably connected to the vehicle body 210, and the side of the second door 230 away from the first door 220 may be rotatably connected to the vehicle body 210, etc., which is not limited here.

[0107] The technical solution provided in the embodiments of the present application is described below in conjunction with specific embodiments.

[0108] Embodiment 1:

[0109] The driving device 100 includes a hinge assembly 10 and a driving assembly 20. The hinge assembly 10 includes a rotating arm 11. The rotating arm 11 includes a first end 111 and a second end 112 that are arranged opposite to each other. The first end 111 is used to be rotatably connected to a vehicle body 210 of a vehicle 200, and the second end 112 is used to be rotatably connected to a first door 220 of the vehicle 200. The driving assembly 20 includes a driving arm 21. The driving arm 21 includes a connecting end 211 and a driving end 212 that are arranged opposite to each other. The connecting end 211 is used to be rotatably connected to the vehicle body 210, and the driving end 212 is used to be connected to the first door 220. The rotating arm 11 can rotate 48° with the first end 111 as an axis, so that the first door 220 switches between a closed state S1 and a first open state S2. The driving end 212 can move along the length direction X of the first door 220 to drive the first door 220 to rotate 75° with the second end 112 as an axis, so that the first door 220 switches between a second open state S3 and a first open state S2.

[0110] The rotating arm 11 in the hinge assembly 10 and the driving arm 21 in the driving assembly 20 form a dual driving structure for the first door 220. Specifically, in the opening stage of the first door 220, the rotating arm 11 is firstly rotated 48° with the first end 111 as the axis, so that the first door 220 moves from the closed state S1 to the first open state S2, and then the driving end 212 of the driving arm 21 moves along the length direction X of the first door 220, and then the first door 220 is driven to rotate 75° with the second end 112 as the axis through the rotation connection between the connecting end 211 and the vehicle body 210, so that the first door 220 moves from the first open state S2 to the second open state S3, thereby realizing the two-stage opening structure of the first door 220, and then realizing the large-angle opening structure of the first door 220, effectively increasing the opening range of the first door, and then improving the convenience of passengers getting on and off the vehicle and carrying items such as luggage.

[0111] Moreover, the two-stage opening structure of the first door 220, especially the movement of the first door 220 from the closed state S1 to the first open state S2, can effectively avoid the interference between the first door 220 and the second door 230 during the opening process, ensuring that the first door 220 can be opened smoothly. The motion envelopes of the first door 220 and the second door 230 do not overlap, avoiding the problem of interference between the first door 220 and the second door 230 during the opening and closing process. The drive device 100 provided in the embodiment of the present application can adapt to the needs of various vehicle models for a B-pillar-free double-door design.

[0112] Embodiment 2:

[0113] The hinge assembly 10 further includes a first mounting member 12 and a second mounting member 13. The first mounting member 12 is used to be mounted on the vehicle body 210. The rotating arm 11 is rotatably connected to the first mounting member 12 via the first end 111. The second mounting member 13 is used to be mounted on the first door 220. The first door 220 is rotatably connected to the second end 112 via the second mounting member 13. The provision of the first mounting member 12 can ensure the connection stability between the rotating arm 11 and the vehicle body 210, and further ensure the stability of the rotating arm 11 rotating around the first end 111. The provision of the second mounting member 13 can ensure the connection stability between the rotating arm 11 and the first door 220, and further ensure the stability of the first door 220 rotating around the second end 112.

[0114] The driving assembly 20 also includes a third mounting member 22, which is used to be installed on the vehicle body 210. The connecting end 211 of the driving arm 21 is rotatably connected to the third mounting member 22.
