Description

Technical Field

[0001] The present application relates to the technical field of roof structures, and in particular to a roof assembly, a roof system and a vehicle. Background Art

[0002] In vehicles such as sports cars, roofs can be switched between deployed and stowed positions to meet user comfort needs. With technological advancements, users are no longer satisfied with just fully open or fully closed options, and are seeking more flexible opening and closing methods. However, existing technologies often fail to meet this customer demand. Summary of the Invention

[0003] The purpose of the present application is to provide a roof assembly, a roof system and a vehicle, aiming to solve the problem of how to improve the opening and closing flexibility of the vehicle roof.

[0004] In a first aspect, a roof assembly is provided for use with a vehicle, comprising a first roof unit, a second roof unit, a first drive assembly and a second drive assembly, wherein the first drive assembly is connected to the first roof unit and is used to drive the first roof unit to flip between a deployed position and a stowed position, and the second drive assembly is connected to the second roof unit and is used to drive the second roof unit to flip between a deployed position and a stowed position.

[0005] Because the first and second roof units are driven by the first and second drive assemblies, respectively, they can be driven independently. The first and second roof units can also be simultaneously rotated from the deployed position to the stowed position, or vice versa, driven by the first and second drive assemblies. Furthermore, while the first drive assembly rotates the first roof unit to the stowed position, the second roof unit can remain in the deployed position. While the first roof unit is in the deployed position, the second roof unit can remain in the stowed position. This increases the flexibility of opening and closing the roof assembly, enhancing its adaptability to various environmental conditions. This split-panel design allows the driver and front passenger seats to independently open and close the roof as needed. For example, on a clear day, if the driver wants to enjoy the sunshine while the front passenger seat needs to block direct sunlight, they can simply open the roof unit above the driver's seat. This personalized choice not only improves the comfort of the passengers, but also adds more fun and flexibility to the driving experience.

[0006] Optionally, when the first roof unit and the second roof unit are in the deployed position, the first roof unit and the second roof unit are aligned along the width direction of the vehicle, thereby improving the control flexibility of the roof in the width direction of the vehicle.

[0007] Optionally, when the first and second roof units are in the deployed positions, the first roof unit is located above the driver's seat of the vehicle, and the second roof unit is located above the passenger seat of the vehicle. In this way, the first and second roof units can be independently controlled, thereby enhancing the control flexibility of the roofs for the driver's seat and the passenger seat.

[0008] Optionally, when the first roof unit and the second roof unit are in the stowed position, the first roof unit and the second roof unit are stacked in the height direction of the vehicle. This saves space in the vehicle occupied by the first roof unit and the second roof unit in the stowed position, thereby increasing space in other areas of the vehicle (such as the trunk).

[0009] Optionally, when the first roof unit and the second roof unit are in the deployed position, the first roof unit is located above the main driver's seat of the vehicle, and the second roof unit is located above the passenger seat of the vehicle. When the first roof unit and the second roof unit are in the stowed position, the second roof unit is stacked above the first roof unit. In this way, since the second roof unit is located above the first roof unit, it can switch between the deployed and stowed positions while the first roof unit remains in the stowed position, without the first roof unit interfering with the second roof unit. Therefore, the second roof unit has greater driving flexibility than the first roof unit. The second roof unit is also the passenger roof unit, and the passenger roof unit is switched more frequently than the main driver's roof unit. Therefore, arranging the second roof unit above the first roof unit is more reasonable and helps reduce control complexity.

[0010] Optionally, the first drive assembly is further configured to drive the first roof unit to rotate by a first preset angle in a first direction within a plane perpendicular to the height of the vehicle when the first roof unit is flipped from the deployed position to the stowed position, and the second drive assembly is further configured to drive the second roof unit to rotate by a second preset angle in a second direction within a plane perpendicular to the height of the vehicle when the second roof unit is flipped from the deployed position to the stowed position. The second direction is opposite to the first direction, and both the second preset angle and the first preset angle are greater than or equal to 80° and less than or equal to 100°. In this regard, since the roof units are not flat plates, but rather have a substantially flat shape at their ends facing each other along the width of the vehicle and a curved shape at their ends facing away from each other, toward the bottom of the vehicle. Therefore, during the flipping process, the first and second roof units rotate approximately 90° in opposite directions, allowing them to fit together effectively in the stowed position, reducing storage space.

[0011] Optionally, the first drive assembly includes a first rotary drive member, a first connecting rod, a second connecting rod, and a third connecting rod. One end of the first connecting rod and one end of the second connecting rod are adapted to be rotatably connected to the vehicle body, the first rotary drive member is adapted to drive the one end of the first connecting rod and / or the one end of the second connecting rod to rotate relative to the vehicle body, the other end of the first connecting rod and the other end of the second connecting rod are respectively rotatably connected to the two ends of the third connecting rod, and the first roof unit is connected to the third connecting rod. In this way, the vehicle body, the first connecting rod, the second connecting rod, and the third connecting rod form a hinged four-bar linkage. The hinged four-bar linkage has one degree of freedom, excellent transmission stability, and can also effectively absorb and disperse various external impact forces, thereby improving the durability and reliability of the overall system.

[0012] Optionally, the first drive assembly further includes a first cantilever beam and a second rotational drive member, wherein one end of the first cantilever beam is connected to the third connecting rod, the second rotational drive member is provided at the other end of the first cantilever beam, the first roof unit is connected to the output end of the second rotational drive member, and the second rotational drive member is configured to drive the first roof unit to rotate about the first direction by the first preset angle within a plane perpendicular to the height direction of the vehicle. This structure is simple and has a reasonable layout.

[0013] Optionally, the first and second rotary drive members include servo motors. Servo motors offer high drive precision, facilitating precise control of the position of the first roof unit. Of course, in other embodiments, the first and second rotary drive members may also be DC motors, AC motors, stepper motors, and the like. This application does not impose specific limitations on this.

[0014] Optionally, the second drive assembly includes a third rotary drive member, a fourth link, a fifth link, and a sixth link. One end of the fourth link and one end of the fifth link are adapted to be rotatably connected to the vehicle body, the third rotary drive member is adapted to drive the one end of the fourth link and / or the one end of the fifth link to rotate relative to the vehicle body, the other end of the fourth link and the other end of the fifth link are respectively rotatably connected to the two ends of the sixth link, and the second roof unit is connected to the sixth link. In this way, the vehicle body, the fourth link, the fifth link, and the sixth link form a hinged four-bar mechanism, which has one degree of freedom and excellent transmission stability. It can also effectively absorb and disperse various external impact forces, thereby improving the durability and reliability of the overall system.

[0015] Optionally, the second drive assembly further includes a second cantilever beam and a fourth rotational drive member, wherein one end of the second cantilever beam is connected to the sixth connecting rod, the fourth rotational drive member is provided at the other end of the second cantilever beam, the second roof unit is connected to the output end of the fourth rotational drive member, and the fourth rotational drive member is configured to drive the second roof unit to rotate about the second direction by the second preset angle within a plane perpendicular to the height direction of the vehicle. This structure is simple and has a reasonable layout.

[0016] Optionally, the third rotation driving member and the fourth rotation driving member include servo motors.

[0017] In a second aspect, a roof system is provided, which includes a control unit and a roof assembly as described in any of the above technical solutions, wherein the control unit is connected to a first drive assembly and a second drive assembly of the roof assembly.

[0018] Since the roof system provided in the present application includes the roof assembly described in any of the above technical solutions, both can solve the same problem and achieve the same effect.

[0019] In a third aspect, a vehicle is provided, comprising a roof assembly as described in any of the above technical solutions, or a roof system as described in the above technical solutions.

[0020] Since the vehicle provided in the present application includes the roof assembly described in any of the above technical solutions or the roof system described in the above technical solutions, both can solve the same problem and achieve the same effect.

[0021] Optionally, the vehicle further comprises a body, and the roof assembly is connected to the body. This layout is reasonable and easy to implement.

[0022] Optionally, the vehicle body is provided with a storage compartment. When the first roof unit and the second roof unit of the roof assembly are in the stowed position, the first roof unit and the second roof unit are located within the storage compartment. Thus, the storage compartment accommodates the first and second roof units in the stowed position, preventing the roof units from being exposed, thereby facilitating a consistent appearance of the vehicle.

[0023] Optionally, the top of the accommodating compartment is provided with an opening, through which the first roof unit and the second roof unit are moved between the stowed position and the deployed position. The vehicle further includes a cover body connected to the vehicle body and configured to open or close the opening. This allows the cover body to conceal the first and second roof units, ensuring a consistent appearance.

[0024] Optionally, the accommodating compartment is located between the passenger compartment and the rear of the vehicle along the length of the vehicle. This prevents the roof unit from obstructing the driver's view when switching between the deployed and folded positions. Furthermore, the rear of the vehicle provides ample space to accommodate the roof unit. This layout is reasonable and easy to implement.

[0025] Optionally, the vehicle further includes a trunk located between the passenger compartment of the vehicle body and the rear portion of the vehicle body, with at least a portion of the trunk located below the storage compartment in the height direction of the vehicle. The trunk can be used to store cargo and carry large items, making it suitable for long-distance travel, and the trunk does not interfere with the storage compartment.

For example, "perpendicular" includes absolute perpendicularity and approximately perpendicularity, wherein the acceptable deviation range of approximately perpendicularity can also be, for example, within 5°.

[0039] The present application provides a roof assembly, which is applied to a vehicle, including but not limited to a sports car, a sedan, an off-road vehicle, etc. The present application is exemplified by taking a sports car as an example.

[0040] See also Figure 1 , Figure 1This is a schematic diagram of the structure of a roof assembly provided in this application when installed on a vehicle. The roof assembly includes a first roof unit 9, a second roof unit 10, a first drive assembly and a second drive assembly. The first drive assembly is connected to the first roof unit 9 and is used to drive the first roof unit 9 to flip between the deployed position and the stored position. The second drive assembly is connected to the second roof unit 10 and is used to drive the second roof unit 10 to flip between the deployed position and the stored position. Figure 1 In FIG. 1 , the first roof unit 9 and the second roof unit 10 are both in the deployed position.

[0041] When the first roof unit 9 and the second roof unit 10 are in the unfolded position, refer to Figure 1 The first roof unit 9 and the second roof unit 10 cover the roof window of the vehicle to prevent rain and dust from entering the passenger compartment of the vehicle. When the first roof unit 9 and the second roof unit 10 are in the storage position, the first roof unit 9 and the second roof unit 10 are stored in the vehicle body, the roof window of the vehicle is open, and sunlight and wind can enter the passenger compartment, providing a comfortable experience for users.

[0042] Since the first roof unit 9 and the second roof unit 10 are driven by the first driving assembly and the second driving assembly respectively, the first roof unit 9 and the second roof unit 10 can be driven independently. Figure 2-Figure 5 , Figure 2 for Figure 1 The schematic diagram of the structure of the roof assembly shown in the process of partially opening the roof unit, Figure 3 for Figure 1 The schematic diagram of the structure of the roof assembly shown in the figure is in the process of opening all the roof units. Figure 4 for Figure 1 The schematic diagram of the structure of the roof unit in the roof assembly shown is when it is flipped to the storage position. Figure 5 for Figure 1The diagram shows the structure of the roof assembly with the roof unit in the stowed position. The first roof unit 9 and the second roof unit 10 can also be simultaneously rotated from the deployed position to the stowed position, or vice versa, driven by the first and second drive assemblies, respectively. Furthermore, while the first drive assembly drives the first roof unit 9 to the stowed position, the second roof unit 10 can remain in the deployed position. While the first roof unit 9 is in the deployed position, the second roof unit 10 can remain in the stowed position. This enhances the flexibility of opening and closing the roof assembly, improving its adaptability to various environmental conditions. This segmented design allows the driver and front passenger seats to independently open and close the roof as needed. For example, on a sunny day, if the driver wants to enjoy the sunshine while the front passenger seat needs to block direct sunlight, they can simply open the roof unit above the driver's seat. This personalized option not only improves passenger comfort but also adds more fun and flexibility to the driving experience.

[0043] In some embodiments, see Figure 1 When the first and second roof units 9, 10 are in the deployed position, they can be aligned along the width of the vehicle. This improves the control flexibility of the roof in the width direction of the vehicle. Of course, in other embodiments, when the first and second roof units 9, 10 are in the deployed position, they can also be aligned along the length of the vehicle.

[0044] In some embodiments, see Figure 1 When the first roof unit 9 and the second roof unit 10 are in the deployed position, the first roof unit 9 is located above the driver's seat of the vehicle, and the second roof unit 10 is located above the passenger seat of the vehicle. This allows for independent control of the first roof unit 9 and the second roof unit 10, improving control flexibility for the driver's and passenger seat roofs.

[0045] In some embodiments, see Figure 4 and Figure 5 When the first roof unit 9 and the second roof unit 10 are in the stowed position, the first roof unit 9 and the second roof unit 10 are stacked in the vehicle height direction. This saves space in the vehicle occupied by the first roof unit 9 and the second roof unit 10 in the stowed position, thereby increasing space in other areas of the vehicle (such as the trunk).

[0046] In some embodiments, see Figure 4 and Figure 5When the first roof unit 9 and the second roof unit 10 are in the deployed position, the first roof unit 9 is located above the main driver's seat of the vehicle, and the second roof unit 10 is located above the passenger seat of the vehicle. When the first roof unit 9 and the second roof unit 10 are in the stowed position, the second roof unit 10 is stacked above the first roof unit 9.

[0047] In this way, since the second roof unit 10 is located on the upper layer of the first roof unit 9, when the first roof unit 9 remains in the storage position, the second roof unit 10 can switch between the deployed position and the storage position, and the first roof unit 9 will not interfere with the second roof unit 10. Therefore, the driving flexibility of the second roof unit 10 is better than the driving flexibility of the first roof unit 9. The second roof unit 10 is also the co-pilot roof unit. Compared with the main driver's roof unit, the co-pilot roof unit is switched more frequently. Therefore, the design of arranging the second roof unit 10 above the first roof unit 9 is more reasonable and helps to reduce the control complexity.

[0048] In some embodiments, the first drive assembly is further used to drive the first roof unit 9 to rotate about a first preset angle in a first direction in a plane perpendicular to the height direction of the vehicle when the first roof unit 9 is flipped from the deployed position to the stowed position; the second drive assembly is further used to drive the second roof unit 10 to rotate about a second preset angle in a second direction in a plane perpendicular to the height direction of the vehicle when the second roof unit 10 is flipped from the deployed position to the stowed position.

[0049] The second direction is opposite to the first direction. For example, when viewed from above, the first roof unit 9 rotates clockwise, while the second roof unit 10 rotates counterclockwise. Alternatively, when viewed from above, the first roof unit 9 rotates counterclockwise, while the second roof unit 10 rotates clockwise. The second preset angle and the first preset angle are both greater than or equal to 80° and less than or equal to 100°. In other words, the rotation angle between the first roof unit 9 and the second roof unit 10 is approximately 90°. Because the roof units are not flat, but rather have a substantially flat shape along the width of the vehicle, with the ends facing each other being approximately flat and the ends facing each other being curved toward the bottom of the vehicle, during the flipping process, the first roof unit 9 and the second roof unit 10 rotate approximately 90° in opposite directions, allowing them to fit together effectively in the stowed position, reducing storage space.

[0050] Of course, conversely, the first driving assembly is also used to drive the first roof unit 9 to rotate in a plane perpendicular to the height direction of the vehicle by a first preset angle in the opposite direction of the first direction when the first roof unit 9 is flipped from the stowed position to the deployed position; and the second driving assembly is also used to drive the second roof unit 10 to rotate in a plane perpendicular to the height direction of the vehicle by a second preset angle in the opposite direction of the second direction when the second roof unit 10 is flipped from the stowed position to the deployed position, thereby achieving reset.

[0051] There are various structural forms of the first drive assembly.

[0052] In some embodiments, see Figure 6 , Figure 6 for Figure 1 The first driving assembly includes a first rotating driving member (not shown), a first connecting rod 1 , a second connecting rod 2 and a third connecting rod 3 .

[0053] Among them, one end of the first link 1 and one end of the second link 2 are suitable for being rotatably connected to the vehicle body. Specifically, one end of the first link 1 can be rotatably connected to the vehicle body via a first rotating shaft 12, and one end of the second link 2 can be rotatably connected to the vehicle body via a second rotating shaft 13. The first rotating shaft 12 and the second rotating shaft 13 are not colinear, that is, they are arranged at an interval. The first rotary drive member is suitable for driving the one end of the first link 1 and / or the one end of the second link 2 to rotate relative to the vehicle body. The other end of the first link 1 and the other end of the second link 2 are rotatably connected to the two ends of the third link 3 respectively. Specifically, the rotating shaft between the first link 1 and the third link 3 is marked as the third rotating shaft 15, and the rotating shaft between the second link 2 and the third link 3 is marked as the fourth rotating shaft 14. The first roof unit 9 is connected to the third link 3. In this way, the vehicle body, the first link 1, the second link 2 and the third link 3 form a hinged four-bar mechanism. The hinged four-bar mechanism has 1 degree of freedom and better transmission stability. At the same time, it can effectively absorb and disperse various external impact forces, thereby improving the durability and reliability of the overall system.

[0054] On the basis of the above, the first roof unit 9 can be directly connected to the third link 3, or indirectly connected to the third link 3 via other intermediate structures. Figure 6 The first drive assembly further includes a first cantilever beam 01 and a second rotary drive member 4. One end of the first cantilever beam 01 is connected to the third connecting rod 3, and the second rotary drive member 4 is provided at the other end of the first cantilever beam 01. The first roof unit 9 is connected to the output end of the second rotary drive member 4. The second rotary drive member 4 is used to drive the first roof unit 9 to rotate in a first direction within a plane perpendicular to the height direction of the vehicle by the aforementioned first predetermined angle. This results in a simple structure and a rational layout.

[0055] In some embodiments, the first and second rotary drive members 4 may comprise servo motors. Servo motors offer high drive precision, facilitating precise control of the position of the first roof unit 9. Of course, in other embodiments, the first and second rotary drive members 4 may also be DC motors, AC motors, stepper motors, and the like. This application does not impose specific limitations on this.

[0056] Similarly, please continue to read Figure 6 The second drive assembly may include a third rotary drive member (not shown), a fourth link 5, a fifth link 6, and a sixth link 7. One end of the fourth link 5 and one end of the fifth link 6 are adapted to be rotatably connected to the vehicle body. Specifically, one end of the fourth link 5 can be rotatably connected to the vehicle body via a fifth rotating shaft 17, and one end of the fifth link 6 can be rotatably connected to the vehicle body via a sixth rotating shaft 16. The fifth rotating shaft 17 and the sixth rotating shaft 16 are not collinear, that is, they are spaced apart. The second rotary drive member is adapted to drive the one end of the fourth link 5 and / or the one end of the fifth link 6 to rotate relative to the vehicle body. The other ends of the fourth link 5 and the other ends of the fifth link 6 are rotatably connected to the two ends of the sixth link 7, respectively. The second roof unit 10 is connected to the sixth link 7. In this way, the vehicle body, the fourth link 5, the fifth link 6, and the sixth link 7 form a hinged four-bar linkage. This hinged four-bar linkage has one degree of freedom, resulting in excellent transmission stability. It can also effectively absorb and disperse various external impact forces, thereby improving the durability and reliability of the overall system.

[0057] On the basis of the above, the second roof unit 10 can be directly connected to the sixth link 7, or indirectly connected to the sixth link 7 via other intermediate structures. Figure 6 The second drive assembly further includes a second cantilever beam 02 and a fourth rotary drive member 8. One end of the second cantilever beam 02 is connected to the sixth connecting rod 7. The fourth rotary drive member 8 is disposed at the other end of the second cantilever beam 02. The second roof unit 10 is connected to the output end of the fourth rotary drive member 8. The fourth rotary drive member 8 is configured to drive the second roof unit 10 to rotate in a second direction by a second predetermined angle within a plane perpendicular to the height direction of the vehicle. This results in a simple structure and a reasonable layout.

[0058] In some embodiments, the third and fourth rotary drive members 8 may comprise servo motors. Servo motors offer high drive precision, facilitating precise control of the position of the second roof unit 10. Of course, in other embodiments, the third and fourth rotary drive members 8 may also be DC motors, AC motors, stepper motors, and the like. This application does not impose specific limitations on this.

[0059] The present application also provides a roof system comprising a roof assembly as described in any of the above embodiments and a control unit, wherein the control unit is connected to a first drive assembly and a second drive assembly of the roof assembly, and the control unit is configured to control the first drive assembly and the second drive assembly to respectively drive the first roof unit and the second roof unit to flip between a deployed position and a stowed position. In this manner, the control unit can achieve automated control of the first drive assembly and the second drive assembly.

[0060] Specifically, in some embodiments, when the control unit receives the first instruction information, it can control the first drive assembly to drive the first roof unit to flip from the deployed position to the stowed position. When the control unit receives the second instruction information, it can control the first drive assembly to drive the first roof unit to flip from the stowed position to the deployed position. When the control unit receives the third instruction information, it can control the second drive assembly to drive the second roof unit to flip from the deployed position to the stowed position. When the control unit receives the fourth instruction information, it can control the second drive assembly to drive the second roof unit to flip from the stowed position to the deployed position. When the control unit receives the fifth instruction information, it can control the first drive assembly and the second drive assembly to respectively drive the first roof unit and the second roof unit to flip from the deployed position to the stowed position. When the control unit receives the sixth instruction information, it can control the first drive assembly and the second drive assembly to respectively drive the first roof unit and the second roof unit to flip from the stowed position to the deployed position.

[0061] The above-mentioned first instruction information, second instruction information, third instruction information, fourth instruction information, fifth instruction information and sixth instruction information can be triggered by the control panel or display device in the vehicle, or can be triggered by the user's smartphone through wireless communication. This application does not make any specific restrictions on this.

[0062] In some embodiments, the control unit is further configured to control the first drive assembly and the second drive assembly to respectively drive the first roof unit and the second roof unit at a faster speed according to the running speed of the vehicle. Specifically, the faster the running speed of the vehicle, the faster the first drive assembly and the second drive assembly respectively drive the first roof unit and the second roof unit.

[0063] In this way, wind resistance can be reduced during the switching process, ensuring safety and smoothness during driving.

[0064] The control unit may include sensors and processors, and the sensors are used to monitor the movement status of the first roof unit 9 and the second roof unit 10 in real time, thereby implementing closed-loop control to ensure the stability and safety of the first roof unit 9 and the second roof unit 10 under various environmental conditions.

[0065] See also Figure 1-Figure 5The present application also provides a vehicle, which comprises a roof assembly as described in any of the above embodiments, or a roof system as described in any of the above embodiments.

[0066] Since the vehicle provided in the embodiments of the present application includes a roof assembly as described in any of the above embodiments or a roof system as described in any of the above embodiments, both can solve the same problem and achieve the same effect.

[0067] In some embodiments, the vehicle further includes a body, and the roof assembly is connected to the body.

[0068] In some embodiments, the vehicle body is provided with a storage compartment. This compartment can be located at the rear or front of the vehicle body. This application illustrates the rear location of the compartment as an example. When the first and second roof units 9, 10 of the roof assembly are in the stowed position, they are located within the storage compartment. This compartment, which houses the stowed first and second roof units 9, 10, prevents the roof units from being exposed, thus ensuring a consistent appearance for the vehicle.

[0069] In some embodiments, the top of the compartment is provided with an opening, through which the first roof unit 9 and the second roof unit 10 move between the stowed and deployed positions. Furthermore, the vehicle further includes a cover 11, which is attached to the vehicle body and is used to open and close the opening. This allows the cover 11 to conceal the first and second roof units 9, 10, ensuring a consistent appearance.

[0070] In some embodiments, the accommodating compartment is located between the passenger compartment and the rear of the vehicle along its length. This prevents the roof unit from obstructing the driver's view when switching between the deployed and folded positions. Furthermore, the rear of the vehicle provides ample space to accommodate the roof unit. This layout is both reasonable and easy to implement.

[0071] In some embodiments, the vehicle further includes a trunk located between the passenger compartment and the rear of the vehicle body, with at least a portion of the trunk located below the storage compartment along the vehicle height.
