Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] This application provides a driving device and a vehicle, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0055] In some embodiments of this application, a vehicle 200 is provided, with reference to... Figures 1 to 7The vehicle 200 includes a body 210, a first door 220, and a second door 230. The vehicle 200 can adopt a pillarless, double-door design. Specifically, the first door 220 and the second door 230 are located on the same side of the body 210. The first door 220 is rotatably connected to the body 210 via a drive device 100. That is, the side of the first door 220 away from the second door 230 is rotatably connected to the body 210 via the drive device 100, and the side of the second door 230 away from the first door 220 is rotatably connected to the body 210. Thus, the first door 220 and the second door 230 are double-door structures. The first door 220 can be located near the rear of the vehicle, i.e., the first door 220 is the rear door. Correspondingly, the second door 230 can be located near the front of the vehicle, i.e., the second door 230 is the front door.

[0056] Of course, in other embodiments of this application, the second door 230 and the vehicle body 210 can also be rotatably connected via the drive device 100. Furthermore, the first door 220 can be positioned closer to the front of the vehicle 200, i.e., the first door 220 is the front door of the vehicle 200, and the second door 230 can be positioned closer to 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 of this application is not limited to a pillarless double-door design; for example, the side of the first door 220 closest to the second door 230 can be rotatably connected to the vehicle body 210, and the side of the second door 230 furthest from the first door 220 can be rotatably connected to the vehicle body 210, etc., and this is not limited here.

[0057] Among them, reference Figures 1 to 7 as well as Figure 10 The first door 220 includes a movable side 221 and a connecting side 222 disposed opposite to each other along its length direction X. The movable side 221 is the side of the first door 220 closer to the second door 230, and the connecting side 222 is the side of the first door 220 away from the second door 230.

[0058] In some embodiments of this application, a driving device 100 is provided, with reference to... Figures 1-2 , Figures 4-6 as well as Figures 8-11 The drive unit 100 includes a hinge assembly 10 and a drive assembly 20.

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

[0060] Reference Figures 1-2 , Figures 4-6 as well as Figures 12-13 The drive assembly 20 includes a drive arm 21, which includes a connecting end 211 and a drive end 212 disposed opposite to each other, as shown in the figure. Figure 2 , Figures 4-6 The connecting end 211 is used to rotatably connect with the vehicle body 210, and the driving end 212 is used to connect with the first door 220.

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

[0062] Most existing vehicles use a four-bar linkage to connect the doors to the vehicle body. Specifically, the fixed arm in the four-bar linkage is mounted on the vehicle body, the movable arm in the four-bar linkage is connected to the door, and the movable arm is rotatably connected to the fixed arm. The door is driven to rotate relative to the vehicle body by the rotation of the movable arm relative to the fixed arm. 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 to the loading and unloading of luggage and other items.

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

[0064] The rotating arm 11 can rotate by a first angle α about its first end 111, allowing the first door 220 to switch between a closed state S1 and a 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, driving the first door 220 to rotate by a second angle β about its second end 112, allowing the first door 220 to switch between a second open state S3 and a 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-drive structure for the first door 220, driving the first door 220 to form a two-stage motion trajectory, effectively increasing the opening range of the first door 220 and improving ease of use.

[0065] Specifically, during the opening phase of the first door 220, the rotating arm 11 is first rotated by a first angle α around the first end 111 as an axis, so that the first door 220 changes from the closed state S1 (as shown in the image). Figure 1 and Figure 2 (As shown) Move to the first open state S2 (as shown) Figure 3 and Figure 4 As shown), the first door 220 moves from the door mounting opening position embedded in the body 210 to the door mounting opening position detached from the body 210. Then, through the drive end 212 of the drive arm 21, it moves along the length direction X of the first door 220. Specifically, the drive end 212 moves along the length direction X of the first door 220 from the movable side 221 towards the connecting side 222. Then, through the rotational connection between the connecting end 211 and the body 210, the first door 220 is driven to rotate positively by a second angle β about the second end 112 as the axis, so that the first door 220 changes from the first open state S2 (as shown). Figure 3 and Figure 4 (As shown) Move to the second open state S3 (as shown) Figure 5 and Figure 6 As shown in the figure, the first door 220 has a two-stage opening structure, namely a first opening state and a second opening state, thereby realizing a large-angle opening structure of the first door 220. Compared with vehicles with existing four-bar linkage structure driving door opening, the driving device 100 provided in this application embodiment can effectively increase the opening range of the first door, thereby improving the convenience of passengers getting on and off the vehicle and the handling of luggage and other items.

[0066] Conversely, during the closing phase of the first door 220, the drive end 212 of the drive arm 21 first moves along the length direction X of the first door 220. Specifically, the drive end 212 moves along the length direction X of the first door 220 from the connecting side 222 towards the moving side 221. Then, through the rotational connection between the connecting end 211 and the vehicle body 210, the first door 220 is driven to rotate in the opposite direction by a second angle β about the second end 112 as an axis, so that the first door 220 moves from the second opening state S3 to the first opening state S2, thereby realizing the closing of the first door 220. 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 position detached from the body 210 to the door mounting position embedded in the body 210, so as to close the first door 220 and ensure the smooth closing of the first door 220.

[0067] Furthermore, 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, effectively avoids interference between the first door 220 and the second door 230 during the opening process, ensuring that the first door 220 can open smoothly. Specifically, as follows... Figure 8 In the illustrated embodiment, it is evident that the motion envelopes of the first door 220 and the second door 230 do not overlap. The drive device 100 provided in this application embodiment avoids the problem of interference between the first door 220 and the second door 230 during opening and closing. The drive device 100 provided in this application embodiment can adapt to the requirements of various vehicle models for pillarless double-door designs.

[0068] In some embodiments, refer to Figure 4The first door 220 moves from the closed state S1 to the first open state S2. 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. The shape of the first trajectory A1 is arc-shaped. Specifically, during the process of the first door 220 moving 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 avoiding the first door 220 from colliding with the second door 230 during the opening process. If interference occurs, the first door 220 can be opened smoothly. Conversely, if the first door 220 moves from the first open state S2 to the closed state S1, 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 towards the second door 230, thereby avoiding interference between the first door 220 and the second door 230 during the closing process and ensuring the smooth closing of the first door 220.

[0069] In some embodiments, refer to Figure 6 The first door 220 moves from the first open state S2 to the second open state S3. The movement trajectory of the first door 220 is the second trajectory A2. That is, the movement trajectory of the movable side 221 of the first door 220 forms the second trajectory A2. The shape of the second trajectory A2 is arc-shaped. Specifically, during 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 movable side 221 of the first door 220 moves further 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 the large angle opening of the first door 220 and increasing the opening range of the first door 220.

[0070] In some embodiments, refer to Figure 2 , Figure 4 , Figure 6 as well as Figure 8 The hinge assembly 10 also includes a first mounting member 12 and a second mounting member 13, as shown in the figure. Figure 2 , Figure 4 as well as Figure 6The first mounting member 12 is used to mount 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 mount on the first door 220, and the first door 220 is rotatably connected to the second end 112 via the second mounting member 13. The first mounting member 12 ensures the connection stability between the rotating arm 11 and the vehicle body 210, thereby ensuring the stability of the rotating arm 11's rotation about the first end 111. The second mounting member 13 ensures the connection stability between the rotating arm 11 and the first door 220, thereby ensuring the stability of the first door 220's rotation about the second end 112.

[0071] In some embodiments, refer to Figure 4 , Figure 6 as well as Figures 9-10 The first mounting member 12 has a first protrusion 121 protruding from one end adjacent to the first end 111, as shown in the figure. Figures 9-10 A second protrusion 1111 protrudes from the first end 111. 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 restrict the rotation of the rotating arm 11. The cooperative design of the first protrusion 121 and the second protrusion 1111 ensures that 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, so that the rotating arm 11, after rotating a first angle α about the first end 111 as the axis, no longer continues to rotate about the first end 111 as the axis. That is, during the process of the first door 220 continuing 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 smoothly and easily from the first open state S2 to the second open state S3.

[0072] In some embodiments, refer to Figure 2 , Figure 4 , Figure 6 as well as Figures 9-11 The first mounting component 12 includes a first mounting base 122 and a first connecting arm 123 connected together, as shown in the figure. Figure 2 , Figure 4 as well as Figure 6 The first mounting component 12 is mounted on the vehicle body 210 via the first mounting seat 122. Specifically, the first mounting seat 122 is detachably mounted on the vehicle body 210 by 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. (Refer to...) Figure 4 , Figure 6 as well as Figures 9-11The first protrusion 121 protrudes from one end of the first connecting arm 123 adjacent to the first end 111.

[0073] In some embodiments, refer to Figure 2 , Figure 4 , Figure 6 as well as Figures 9-11 The second mounting member 13 has a third protrusion 131 protruding from one end adjacent to the second end 112, as shown in the reference. 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 and the second end 112 do not contact each other. Figure 6 and Figure 9 , Figure 11 , Figure 6 The diagram shown is a structural schematic of the first door 220 moving to the second open state S3. Figure 9 and Figure 11 The diagram shows the structural state of the rotating arm 11 when the first door 220 moves to the second open state S3. When the first door 220 moves to the second open state, the third protrusion 131 abuts against the second end 112 to restrict the rotation of the first door 220. The third protrusion 131 can block and restrict the rotation of the first door 220 when it rotates to the second open state S3, thereby preventing the opening range of the first door 220 from being too large. This avoids the situation where the first door 220 collides with the vehicle body 210 due to the excessive opening range, ensuring the opening safety of the first door 220 and ensuring the service life and safety of the vehicle 200.

[0074] In some embodiments, refer to Figure 2 , Figure 4 , Figure 6 as well as Figures 9-11 The second mounting component 13 includes a second mounting base 132 and a second connecting arm 133. The second mounting component 13 is mounted on the first door 220 via the second mounting base 132. Specifically, the second mounting base 132 is detachably mounted on the first door 220 by bolts. One end of the second connecting arm 133 is fixedly connected to the second mounting base 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 base 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 protrudes from one end of the second connecting arm 133 adjacent to the second end 112.

[0075] In some embodiments, refer to Figure 9The third protrusion 131 can rotate by 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. Thus, 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. This makes the rotation angle β of the first door 220 the same as the rotation angle θ of the third protrusion 131. 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 around the second end 112 as an axis, ensuring the opening safety of the first door 220 and ensuring the service life and safety of the vehicle 200.

[0076] In some embodiments, a rotary drive member (not shown in the figure) may be provided on the vehicle body 210 to drive the rotary arm 11 to rotate about the first end 111, thereby forming an automatic drive for the rotary arm 11 to drive the first door 220 to switch between a closed state S1 and a first open state S2. The rotary drive member may be a cylinder or a telescopic motor. In other implementations, the first door 220 may be manually switched between the closed state S1 and the first open state S2 by a passenger. That is, the first door 220 drives the rotary arm 11 to rotate about the first end 111. Specifically, the passenger switches the first door 220 between the closed state S1 and the first open state S2 by using a handle (not shown in the figure) provided on the end of the first door 220 adjacent to the second door 230 along its length direction X.

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

[0078] In some embodiments, refer to Figure 2 , Figure 4 , Figure 6 as well as Figures 12-13The drive assembly 20 also includes a third mounting member 22, which is used to mount on the vehicle body 210. The connecting end 211 of the drive 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 drive arm 21 and the vehicle body 210, thereby ensuring the stability of the drive arm 21 driving the first door 220 to rotate about the second end 112 as an axis.

[0079] In some embodiments, refer to Figure 13 The drive assembly 20 also includes a drive member 23, which is mounted on the first door 220. The drive end 212 of the drive arm 21 is connected to the drive member 23, and the drive member 23 can drive the drive end 212 to move along the length direction X of the first door 220. The drive member 23 is designed to drive the drive end 212 to move along the length direction X of the first door 220. Combined with the structural design of the drive arm 21's connecting end 211 being rotatably connected to the third mounting member 22, the drive end 212 can generate a force through the drive arm 21 during movement. The drive arm 21 then generates a reaction force on the first door 220 through the drive end 212, thereby driving the first door 220 to rotate around the second end 112 as an axis. This ensures the rotational stability of the first door 220 and improves the automaticity of opening and closing the first door 220, saving passengers the effort required to open and close the first door 220.

[0080] In some embodiments, the third mounting member 22 is a ball joint to ensure the stability of the rotatable connection between the connecting end 211 of the drive arm 21 and the third mounting member 22. In other implementations, the third mounting member 22 may adopt other connection structures, as long as it ensures the rotatable connection between the connecting end 211 of the drive arm 21 and the third mounting member 22.

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

[0082] In some embodiments, refer to Figure 13The drive assembly 20 further includes a transmission rod 24 and a slider 25. The transmission rod 24 is mounted 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 drive member 23. The slider 25 is disposed on the transmission rod 24. The drive end 212 of the drive arm 21 is connected to the slider 25. The drive member 23 can drive the transmission rod 24 to move the slider 25 along the length direction X of the first door 220. The slider 25 drives the drive 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 open state S2 and the second open state S3. The cooperative design of the transmission rod 24 and the slider 25 can ensure the stability of the drive end 212 moving along the length direction X of the first door 220, thereby ensuring the stability and smoothness of the first door 220 switching between the first open state S2 and the second open state S3.

[0083] In some embodiments, the driving member 23 is a rotary motor. Specifically, the driving member 23 is a lead screw motor, the transmission rod 24 is a lead screw, and the sliding member 25 is a slider. The sliding member 25 is sleeved on the transmission rod 24. The driving member 23 drives the transmission rod 24 to rotate, thereby causing the sliding member 25 to move along the length direction X of the first door 220, and then causing the driving end 212 to move along the length direction X of the first door 220.

[0084] In some embodiments, refer to Figure 14 The drive assembly 20 also includes a limiting member 26, which includes an elastic part 261 and a stop part 262. The elastic part 261 and the stop part 262 are connected sequentially. The stop part 262 is mounted on the first door 220 via the elastic part 261. The end of the stop part 262 facing away from the elastic part 261 faces the drive rod 24. (Refer to...) Figure 11 The sliding member 25 has a groove 251. The sliding member 25 moves along the length X of the first door 220. The stop 262 can be inserted into the groove 251 to restrict the movement of the sliding member 25. The driving member 23 can drive the transmission rod 24 to separate the sliding member 25 from the stop 262. The cooperative design of the elastic part 261 and the stop 262 in the limiting member 26 allows the sliding member 25 to be in a specific position during its movement along the length X of the first door 220, thereby keeping the first door 220 in a specific state and ensuring the stability and smoothness of opening or closing the first door 220.

[0085] In some embodiments, along the length direction X of the first door 220, a limiting member 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 stop portion 262 can be inserted into the groove 251, thereby keeping the first door 220 in the closed state S1. When the first door 220 is closed, that is, when 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, thereby driving the sliding member 25 to move closer to the movable side 221 along the length direction X of the first door 220. The sliding member 25 pushes the stop portion 262, causing the stop portion 262 to contract along the extension and retraction direction of the elastic portion 261. As the sliding member 25 continues to move closer to the movable side 221, 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 sliding member 25 is held at one end adjacent to the movable side 221, thereby keeping the first door 220 in the closed state S1.

[0086] When the first door 220 is opened, the drive member 23 drives the transmission rod 24 to rotate, thereby causing the sliding member 25 to move away from the movable side 221 along the length direction X of the first door 220. The sliding member 25 pushes against the stop part 262, causing the stop part 262 to contract along the extension and retraction direction of the elastic part 261. As the sliding member 25 continues to move away from the movable side 221, the sliding member 25 separates from the stop part 262, allowing the first door 220 to move to the first open state S2.

[0087] In some embodiments, along the length direction X of the first door 220, a limiting member 26 is disposed at one end of the first door 220 adjacent to the connecting side 222. When the first door 220 moves to the second open state S3, the stop portion 262 can be inserted into the groove 251, thereby keeping the first door 220 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, thereby driving the sliding member 25 to move closer to the connecting side 222 along the length direction X of the first door 220. The sliding member 25 pushes the stop portion 262, causing the stop portion 262 to contract along the extension and retraction direction of the elastic portion 261. As the sliding member 25 moves closer to the connecting side 222, 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 sliding member 25 is held at one end adjacent to the connecting side 222, thereby keeping the first door 220 in the second open state S3.

[0088] When the first door 220 is closed, the drive member 23 drives the transmission rod 24 to rotate, thereby causing the sliding member 25 to move away from the connecting side 222 along the length direction X of the first door 220. The sliding member 25 pushes against the stop part 262, causing the stop part 262 to contract along the extension and retraction direction of the elastic part 261. As the sliding member 25 continues to move away from the connecting side 222, the sliding member 25 separates from the stop part 262, allowing the first door 220 to move from the second open state S3 to the first open state S2.

[0089] In some embodiments, along the length X of the first door 220, a limiting member 26 is disposed between the connecting side 222 and the movable side 221. When the first door 220 moves to the first open state S2, the stop portion 262 can be inserted into the groove 251, thereby keeping the first door 220 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, thereby driving the sliding member 25 away from the connecting side 222 along the length X of the first door 220. The sliding member 25 pushes the stop portion 262, causing the stop portion 262 to contract along the extension and retraction 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, thereby keeping the first door 220 in the first open state S2; When the first door 220 moves from the closed state S1 to the first open state S2, the drive member 23 drives the transmission rod 24 to rotate, thereby causing the sliding member 25 to move away from the movable side 221 along the length direction X of the first door 220. The sliding member 25 pushes the stop part 262, causing the stop part 262 to contract along the extension and retraction direction of the elastic part 261. As the first door 220 moves to the first open state S2, the stop part 262 is inserted into the groove 251 under the action of the elastic deformation of the elastic part 261, so that the first door 220 is kept in the first open state S2.

[0090] In some embodiments, refer to Figure 2 , Figure 4 , Figure 6 as well as Figures 12-14 The drive 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 disposed on the side of the first door 220 facing the vehicle body 210. A receiving groove is provided on the side of the receiving member 27 facing the vehicle body 210. The drive member 23, the transmission rod 24, the sliding member 25 and the limiting member 26 are all disposed in the receiving groove of the receiving member 27. The end of the elastic part 261 facing away from the stop part 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°, and 51°, or any value within a range of any two values. When the value of α is within the above range, it ensures that the first door 220 smoothly and stably switches between the closed state S1 and the first open state S2, and also allows the drive device 100 to be adapted to various vehicle models, such as sedans and SUVs (i.e., sport utility vehicles).

[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 from 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, and 80°, or any value within a range of any two values. When the value of β is within the above range, it ensures that the first door 220 smoothly and stably switches between the first opening state S2 and the second opening state S3, and also allows the drive device 100 to be adapted to various vehicle models, such as sedans and SUVs (i.e., sportutility vehicles).

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

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

[0096] In some embodiments, refer to Figure 6 The first door 220 moves from the first open state S2 to the second open state S3. The movement trajectory of the first door 220 is the second trajectory A2. That is, the movement trajectory of the movable side 221 of the first door 220 forms the second trajectory A2. 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 the large angle opening of the first door 220.

[0097] In some embodiments, refer to Figure 6The drive end 212 moves a distance L mm along the length direction X of the first door 220, satisfying: 350 mm ≤ L ≤ 450 mm. Specifically, the value of L can be any value from 350 mm, 360 mm, 370 mm, 380 mm, 390 mm, 400 mm, 410 mm, 420 mm, 430 mm, 440 mm, and 450 mm, or any value within a range 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 smoothly and stably switch between the first opening state S2 and the second opening state S3.

[0098] In some embodiments, when the first door 220 switches between a closed state S1 and a first open state S2, the drive arm 21 can rotate 18° to 28° about the connecting end 211. Specifically, the drive arm 21 can rotate about the connecting end 211 at any value of 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, and 28°, or any value within a range of any two values. When the angle of rotation of the drive arm 21 about the connecting end 211 is within the above range, the drive arm 21 can follow the movement of the first door 220 as it switches between the closed state S1 and the first open state S2, thereby ensuring the smoothness of the switching between the closed state S1 and the first open state S2 and preventing the drive arm 21 from interfering with the first door 220.

[0099] In some embodiments, the first door 220 switches between a closed state S1 and a first open state S2, and the drive arm 21 can rotate 23° about the connecting end 211 as an axis.

[0100] In some embodiments, the first door 220 switches between a first open state S2 and a second open state S3. The drive arm 21 can rotate 70° to 80° about the connecting end 211. Specifically, the drive arm 21 can rotate about the connecting end 211 by any value of 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, and 80°, or any value within a range of any two values. When the angle of rotation of the drive arm 21 about the connecting end 211 is within the above range, the smoothness of the first door 220 switching between the first open state S2 and the second open state S3 can be guaranteed, thereby ensuring the smoothness of the opening or closing of the first door 220.

[0101] In some embodiments, refer to Figure 5The rotating arm 11 and the drive arm 21 are distributed at intervals 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 drive arm 21 is connected to the sill position of the vehicle body 210. Correspondingly, the receiving member 27 is provided at one end of the first door 220 along the height direction Z of the first door 220 near the sill position, so that the drive device 100 forms a spatial four-bar linkage between the vehicle body 210 and the first door 220, ensuring the connection stability between the drive device 100 and the vehicle body 210 and the first door 220, saving the force required to open or close 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 installed 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, in the example where the first door 220 is the rear door of the vehicle 200, the installation space of the first mounting member 12 is located within the C-pillar structure 2101 of the vehicle body 210. The fact that at least a portion of the first mounting member 12 and the rotating arm 11 are located within the C-pillar structure 2101 of the vehicle body 210 not only enhances the structural strength of the vehicle body 210 and improves the overall structural safety performance, but also optimizes the structural layout of the hinge assembly 10, which is beneficial for improving space utilization. Furthermore, the compact structure of the hinge assembly 10 facilitates the installation design of embedding the hinge assembly 10 into the C-pillar structure 2101, while saving space in the vehicle body 210.

[0103] In some embodiments, refer to Figure 7 The interior of the vehicle body 210 has an installation space (not shown in the figure). In the example where the first door 220 is the rear door of the vehicle 200, the installation space is located within the C-pillar structure 2101 of the vehicle body 210. The vehicle body 210 also has a clearance hole 2102 connecting to the installation space. The first mounting member 12 in the hinge assembly 10 is installed in the installation space. There are two rotating arms 11, spaced apart along the height direction Z of the vehicle body 210. The rotating arms 11 are movably inserted through the clearance hole 2102, allowing the first end 111 of the rotating arm 11 to 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 connected.

[0104] In addition, the hinge assembly 10 is manufactured using a forging process, which helps to ensure the structural stability and safety of the hinge assembly 10 and meet the stringent automotive industry standards.

[0105] In some embodiments, refer to Figure 3 and Figure 4The 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 this application, the second door 230 and the vehicle body 210 can also be rotatably connected via the drive device 100. Furthermore, the first door 220 can be positioned closer to the front of the vehicle, i.e., the first door 220 is the front door of the vehicle 200, and the second door 230 can be positioned closer to 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 this application embodiment is not limited to a pillarless double-door design; for example, the side of the first door 220 closest to the second door 230 can be rotatably connected to the vehicle body 210, and the side of the second door 230 furthest from the first door 220 can be rotatably connected to the vehicle body 210, etc., and this is not limited here.

[0107] The technical solutions provided in the embodiments of this application will be described below with reference to specific examples.

[0108] Example 1:

[0109] The drive unit 100 includes a hinge assembly 10 and a drive assembly 20. The hinge assembly 10 includes a rotating arm 11, which has a first end 111 and a second end 112 disposed opposite to each other. The first end 111 is rotatably connected to the body 210 of the vehicle 200, and the second end 112 is rotatably connected to the first door 220 of the vehicle 200. The drive assembly 20 includes a drive arm 21, which has a connecting end 211 and a drive end 212 disposed opposite to each other. The connecting end 211 is rotatably connected to the body 210, and the drive end 212 is connected to the first door 220. The rotating arm 11 can rotate 48° about 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 drive end 212 can move along the length direction X of the first door 220 to drive the first door 220 to rotate 75° about 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 drive assembly 20 form a dual-drive structure for the first door 220. Specifically, during the opening phase of the first door 220, the rotating arm 11 first rotates 48° in the positive direction around its first end 111, causing the first door 220 to move from the closed state S1 to the first open state S2. Then, the driving end 212 of the driving arm 21 moves along the length direction X of the first door 220. Furthermore, through the rotational connection between the connecting end 211 and the vehicle body 210, the first door 220 is driven to rotate 75° in the positive direction around its second end 112, causing the first door 220 to move from the first open state S2 to the second open state S3. This achieves a two-stage opening structure for the first door 220, thereby realizing a large-angle opening structure for the first door 220, effectively increasing the opening range of the first door, and thus improving the convenience of passengers getting on and off the vehicle and the handling of luggage and other items.

[0111] Furthermore, 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, effectively avoids interference between the first door 220 and the second door 230 during the opening process, ensuring that the first door 220 can open smoothly. The motion envelopes of the first door 220 and the second door 230 do not overlap, avoiding interference between the first door 220 and the second door 230 during opening and closing. The drive device 100 provided in this application embodiment can adapt to the requirements of various vehicle models for pillarless double-door designs.

[0112] Example 2:

[0113] The hinge assembly 10 also includes a first mounting member 12 and a second mounting member 13. The first mounting member 12 is used to mount on the vehicle body 210, and the rotating arm 11 is rotatably connected to the first mounting member 12 via a first end 111. The second mounting member 13 is used to mount on the first door 220, and the first door 220 is rotatably connected to the second end 112 via the second mounting member 13. The first mounting member 12 ensures the connection stability between the rotating arm 11 and the vehicle body 210, thereby ensuring the stability of the rotating arm 11's rotation about the first end 111. The second mounting member 13 ensures the connection stability between the rotating arm 11 and the first door 220, thereby ensuring the stability of the first door 220's rotation about the second end 112.

[0114] The drive assembly 20 also includes a third mounting member 22, which is used to mount on the vehicle body 210. The connecting end 211 of the drive 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 drive arm 21 and the vehicle body 210, thereby ensuring the stability of the drive arm 21 driving the first door 220 to rotate about the second end 112 as an axis.

[0115] Example 3:

[0116] The first mounting member 12 has a first protrusion 121 protruding from one end adjacent to the first end 111, and a second protrusion 1111 protruding from the first end 111. When the first door 220 moves from the closed state S1 to the first open state S2, the first protrusion 121 and the second protrusion 1111 abut against each other to restrict the rotation of the rotating arm 11. The design of the cooperation between the first protrusion 121 and the second protrusion 1111 ensures that when the first door 220 moves from the closed state S1 to the first open state S2, the first protrusion 121 and the second protrusion 1111 abut against each other, so that the rotating arm 11 stops rotating about the first end 111 after rotating 48° about the first end 111. That is, during the process of the first door 220 moving 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 smoothly and easily from the first open state S2 to the second open state S3.

[0117] Example 4:

[0118] The second mounting member 13 has a third protrusion 131 protruding from one end adjacent to the second end 112. 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. When the first door 220 moves to the second open state, the third protrusion 131 abuts against the second end 112 to restrict the rotation of the first door 220. The third protrusion 131 can block and restrict the rotation of the first door 220 when the first door 220 rotates to the second open state S3, thereby preventing the opening range of the first door 220 from being too large, avoiding the situation where the first door 220 collides with the body 210 due to the excessive opening range of the first door 220, thus ensuring the opening safety of the first door 220 and ensuring the service life and safety of the vehicle 200.

[0119] Example 5:

[0120] The drive assembly 20 also includes a drive member 23, which is mounted on the first door 220. The drive end 212 of the drive arm 21 is connected to the drive member 23, and the drive member 23 can drive the drive end 212 to move along the length direction X of the first door 220. The drive member 23 is designed to drive the drive end 212 to move along the length direction X of the first door 220. Combined with the structural design of the drive arm 21's connecting end 211 being rotatably connected to the third mounting member 22, the drive end 212 can generate a force through the drive arm 21 during movement. The drive arm 21 then generates a reaction force on the first door 220 through the drive end 212, thereby driving the first door 220 to rotate around the second end 112 as an axis. This ensures the rotational stability of the first door 220 and improves the automaticity of opening and closing the first door 220, saving passengers the effort required to open and close the first door 220.

[0121] Example 6:

[0122] The drive assembly 20 also includes a transmission rod 24 and a slider 25. The transmission rod 24 is mounted 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 drive member 23. The slider 25 is disposed on the transmission rod 24. The drive end 212 of the drive arm 21 is connected to the slider 25. The drive member 23 is a rotary motor. The drive member 23 can drive the transmission rod 24 to move the slider 25 along the length direction X of the first door 220. The slider 25 drives the drive 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 open state S2 and the second open state S3. The cooperative design of the transmission rod 24 and the slider 25 can ensure the stability of the movement of the drive end 212 along the length direction X of the first door 220, thereby ensuring the stability and smoothness of the first door 220 switching between the first open state S2 and the second open state S3.

[0123] Example 7:

[0124] The drive assembly 20 also includes a limiting member 26, which includes an elastic part 261 and a stop part 262. The elastic part 261 and the stop part 262 are connected sequentially. The stop part 262 is mounted on the first door 220 via the elastic part 261. The end of the stop part 262 facing away from the elastic part 261 faces the transmission rod 24. A groove 251 is provided on the sliding member 25. The sliding member 25 moves along the length direction X of the first door 220. The stop part 262 can be inserted into the groove 251 to restrict the movement of the sliding member 25. The drive member 23 can drive the transmission rod 24 to separate the sliding member 25 from the stop part 262. The cooperative design of the elastic part 261 and the stop part 262 in the limiting member 26 allows the sliding member 25 to be in a specific position during the movement of the sliding member 25 along the length direction X of the first door 220, thereby keeping the first door 220 in a specific state and ensuring the stability and smoothness of opening or closing the first door 220.
