Description

Technical Field

[0001] This application relates to the field of transportation vehicle technology, and more particularly to a steering control device, an instrument panel assembly, and a transportation vehicle. Background Technology

[0002] With the rapid development of intelligent vehicles and autonomous driving technology, retractable steering control devices are gradually becoming an important development direction in intelligent cockpit design. When the vehicle is in advanced autonomous driving mode, the steering control devices can be fully or mostly automatically retracted into the dashboard to free up cockpit space and improve user comfort.

[0003] However, the steering control device in the relevant technology takes up a lot of space after being stored in the dashboard. Summary of the Invention

[0004] The purpose of this application is to provide a steering control device, a dashboard assembly, and a vehicle, which aims to solve the problem of how to reduce the space occupied by the steering control device in the stowed state.

[0005] In a first aspect, a steering control device is provided for use in a vehicle. The steering control device includes a steering control component and a retraction drive device connected to the steering control component. The steering control component includes a central component, and the retraction drive device is used to drive the steering control component to move along a first direction so that the steering control component switches between an on display position and a retracted position. When the steering control component is in the display position, the projected length of the central component in the first direction is L1; the distance the steering control component moves along the first direction from the display position to the storage position is L; L1 and L satisfy: L1≤L; Wherein, the first direction is the forward and backward direction of the vehicle.

[0006] In this way, when the device is stowed, the steering control component can be positioned to coincide with the stowage drive device in the first direction, which can reduce the length of the steering control device in the dashboard along the first direction and reduce the space occupied in the first direction.

[0007] Meanwhile, since the projected length of the central component in the first direction is less than or equal to the driving stroke of the storage drive device along the first direction, the projected length of the central component is relatively short. When the tilt angle is within a certain preset angle range, the length of the central component is relatively short, and the space occupied in the height direction of the vehicle is relatively small, so that sufficient foot space can be reserved below it.

[0034] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0037] In a vehicle 100, such as a vehicle, ship, or train, a steering control device 10 is used to control the direction of travel of the vehicle 100. For an example, please refer to [link to example]. Figure 1 The steering control device 10 is rotated via the steering wheel 13 to achieve directional control of the vehicle 100. With the development of technology, the steering wheel 13 of the steering control device 10 needs to be retracted into the dashboard 5 to meet the user's needs for spatial comfort in scenarios such as intelligent driving and sleeping. The dashboard 5 forms the housing of the instrument panel assembly 20 and is used to house instruments, air conditioning vents, displays, etc.

[0038] Please see Figure 2 When the steering wheel 13 of the steering control device 10 is stored inside the instrument panel 5, it is necessary to reduce the space occupied by the steering control device 10 in order to avoid affecting the layout of other components such as the air conditioner in the dashboard.

[0039] In related technologies, there are many structural forms of the steering control device 10, but when applied to a complete vehicle, corresponding technical problems also arise. For example, the steering control device 10 includes a drive unit and a steering control assembly 1. The steering control assembly 1 is used to control the steering of the wheels, and the drive unit is used to drive the steering control assembly 1 to move between the working state and the retracted state. In the working state, the steering wheel 13 of the steering control assembly 1 is located in the driver's cabin, and the central assembly 11 connecting the steering wheel 13 and the drive unit are located in the instrument panel compartment. The instrument panel 5 separates the instrument panel compartment from the driver's cabin. In addition to the central assembly 11 and the drive unit, the instrument panel compartment also contains the air conditioning system, etc., making the space inside the instrument panel compartment very limited.

[0040] To free up more space in the driver's seat, accommodate more usage scenarios, and improve the user experience, the steering control assembly 1 needs to be stored in the instrument panel using a drive unit in its stowed state. Therefore, the design of the size of the steering control assembly 1 relative to the drive unit is crucial to reducing the space occupied by the steering control assembly 10 in its stowed state.

[0041] Please see Figure 3 , Figure 3 The steering control device 10 is quite long, requiring considerable space to be moved when it is stored in the dashboard. Furthermore, part of the steering control device 10 extends beneath the dashboard and through an opening in the front bulkhead 9 to the outside of the cockpit, connecting with the wheels and other drivetrain components. This results in the steering control device 10 occupying space under the dashboard, thus reducing foot space. Additionally, the opening in the front bulkhead 9 leads to poor sealing of the cockpit, affecting its sound insulation.

[0042] Please see Figure 4 , Figure 4The steering control device 10 includes a first part 10a and a second part 10b extending in different directions. Along the longitudinal direction of the vehicle 100, the overall dimensions of the first part 10a and the second part 10b are relatively large. When the steering control device 10 is in its retracted state, it still requires a certain amount of space to move along the longitudinal direction of the vehicle 100. As a result, the steering control device 10 occupies a large amount of space along the longitudinal direction of the vehicle 100, thus restricting the space layout of the driver's cabin.

[0043] Based on the above description, the steering control device 10 in the related technology occupies a large space after being stored in the dashboard, which is not conducive to the layout of other structures in the dashboard, such as air conditioners.

[0044] To address the aforementioned problems, this application provides a steering control device 10. Please refer to [link to relevant documentation]. Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The steering control device 10 includes a steering control assembly 1 and a storage drive device 2 connected to the steering control assembly 1. The steering control assembly 1 includes a central assembly 11. The storage drive device 2 drives the steering control assembly 1 to move along a first direction, thereby switching the steering control assembly 1 between a display position and a storage position. The first direction refers to the longitudinal direction of the vehicle 100. Taking a vehicle as an example, the longitudinal direction of the vehicle 100 refers to the arrangement direction of the front and rear of the vehicle. Specifically, when the storage drive device 2 drives the steering control assembly 1 to move along the direction from the front to the rear of the vehicle, the steering control assembly 1 switches from a storage position to a display position. When the storage drive device 2 drives the steering control assembly 1 to move along the direction from the rear to the front of the vehicle, the steering control assembly 1 switches from a display position to a storage position.

[0045] For example, when the storage drive device 2 drives the steering control component 1 to switch between the display position and the storage position, the actual movement trajectory of the steering control component 1 may be tilted at a certain angle relative to the first direction. For instance, in one design, the guide rail 22 in the storage drive device 2 is tilted at a certain angle relative to the first direction. When the storage drive device 2 drives the steering control component 1 to move along the guide rail 22 between the storage position and the display position, the actual movement trajectory of the steering control component 1 is consistent with the guiding direction of the guide rail 22 and tilted relative to the first direction. Alternatively, in another design, the guide rail 22 of the storage drive device 2 is parallel to the first direction, but due to installation errors of the storage drive device 2, its actual movement trajectory is tilted at a certain angle relative to the first direction.

[0046] Please refer to the specific details. Figure 10 ,in, Figure 10 When the steering control component 1 is in position (a), it is in the display position; when it is in position (b), it is in the storage position. When the steering control component 1 is in the display position, the projected length of the central component 11 in the first direction is L1. From the display position to the storage position, the moving distance of the steering control component 1 along the first direction is L, where L1 and L satisfy: L1≤L. The projection of the central component 11 in the first direction refers to the projection of the central component 11 onto a reference line extending along the first direction along the height direction of the first vehicle 100. The moving distance of the steering control component 1 along the first direction refers to the distance that the storage drive device 2 can drive the steering control component 1 to move along the first direction.

[0047] In this way, when the steering control component 1 is stowed, the position of the stowage drive device 2 can be made to coincide in the first direction, which can reduce the length of the steering control device 10 in the dashboard along the first direction and reduce the space occupied in the first direction.

[0048] Meanwhile, since the projected length of the central component 11 in the first direction is less than or equal to the driving stroke of the storage drive device 2 along the first direction, the projected length of the central component 11 is relatively short. When the tilt angle is within a certain preset angle range, the length of the central component 11 is relatively short, and the space occupied in the height direction of the vehicle 100 is relatively small, so that sufficient foot space can be reserved below it.

[0049] For example, the storage drive device 2 and the steering control assembly 1 can be directly connected or indirectly connected. For instance, the end of the center assembly 11 away from the steering wheel 13 is directly connected to the storage drive device 2, or the storage drive device 2 is connected to the center assembly 11 through an intermediate structure, which can be other drive devices or structural components, etc.

[0050] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The center assembly 11 includes a first end 11a and a second end 11b, which are located closer to the driver's seat 30 of the vehicle 100 than the first end 11a. The first end 11a and the second end 11b refer to the two ends of the center assembly 11 along its length. When the center assembly 11 is connected between the steering wheel 13 and the hand-feed motor 12, the first end 11a is the end of the center assembly 11 connected to the hand-feed motor 12, and the second end 11b is the end of the center assembly 11 connected to the steering wheel 13.

[0051] When the steering control assembly 1 is in the displayed position, the central assembly 11 is tilted upwards from the first end 11a to the second end 11b. Specifically, the upward tilt of the central assembly 11 from the first end 11a to the second end 11b means that, along the height direction of the vehicle 100, the height of the second end 11b is greater than the height of the first end 11a. This upward tilt of the central assembly 11, when the hand-feed motor 12 points towards the steering wheel 13, conforms to the user's usage habits.

[0052] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The projection of the drive trajectory of the storage drive device 2 in the first direction is the first projection, and the projection of the central component 11 in the first direction is the second projection. The drive trajectory of the storage drive device 2 refers to the movement trajectory of the component connecting the steering control component 1 within the storage drive device 2 from the display position to the storage position. Specifically, it refers to the movement trajectory line formed by connecting the centers of the component's projection in the first plane at various positions during the movement process. The first plane is parallel to both the height direction and the first direction of the vehicle 100. Please refer to... Figure 10 , Figure 10 The trajectory line S is the driving trajectory of the storage drive device 2 in this embodiment.

[0053] For example, when the storage drive device 2 is a guide rail slider structure, the above-mentioned component is a slider; when the storage drive device 2 is a telescopic drive structure, the above-mentioned component is the telescopic end of the telescopic drive structure.

[0054] For example, when the driving device includes a movable component and a driving component, the movable component is connected to the driving component and connected to the steering control assembly 1. When the driving component drives the movable component to move along a first direction, the movable component drives the steering control assembly 1 to move along the first direction. At this time, the driving trajectory of the storage driving device 2 is: the trajectory line along the first direction between the center point of the movable component when the steering control assembly 1 is in the display position and the center point of the movable component when the steering control assembly 1 is in the storage position.

[0055] For example, the driving device includes a telescopic member, one end of which is fixedly installed, and the other end is connected to the steering control assembly 1. By extending and retracting the telescopic member along a first direction, the steering control assembly 1 is driven to switch between an exhibition position and a storage position. At this time, the driving trajectory of the storage driving device 2 is: the trajectory line along the first direction between the connection point of the steering control assembly 1 and the telescopic member when the steering control assembly 1 is in the exhibition position and when the steering control assembly 1 is in the storage position.

[0056] When the steering control component 1 is in the exhibit position, the following conditions are met: the first projection and the second projection do not overlap; or, the overlap length between the first projection and the second projection is less than or equal to 1 / 2 times the length of the second projection; or, the overlap length between the first projection and the second projection is less than or equal to 1 / 4 times the length of the second projection.

[0057] In this way, when the steering control component 1 is in the retracted position, the steering control component 1 and the retracted drive device 2 can be aligned in the first direction, thereby reducing the length of the steering control device 10 in the dashboard along the first direction and reducing the space occupied along the first direction, which can increase the space of the cockpit along the front and rear directions of the vehicle 100.

[0058] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 When the steering control component 1 is in the exhibited position, the projection of the central component 11 in the second direction is the third projection. Along the height direction of the vehicle 100, the following conditions are met: the first end 11a is located above the drive trajectory of the storage drive device 2; or, the first end 11a is flush with the drive trajectory of the storage drive device 2; or, please refer to the specific details. Figure 10 ,in, Figure 10 When the steering control component 1 is in position (a), it is in the display position; when it is in position (b), it is in the storage position. The first end 11a is located below the drive trajectory of the storage drive device 2, and along the height direction of the vehicle 100, the distance from the first end 11a to the drive trajectory of the storage drive device 2 is H, and the third projection length is h. H and h satisfy: H≤1 / 2h; or, H≤1 / 4h; where the second direction is the height direction of the vehicle 100. The first end 11a being flush with the drive range of the storage drive device 2 means that along the height direction of the vehicle 100, the first end 11a and the drive trajectory of the drive device are at the same height. Furthermore, any part of the first end 11a being flush with the drive range is considered to be flush.

[0059] Thus, when the steering control component 1 is in the stowed position, the steering control component 1 and the stowed drive device 2 can be positioned to coincide in the first direction, which can reduce the length of the steering control device 10 in the dashboard along the first direction, thereby reducing the space occupied along the first direction.

[0060] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The storage drive device 2 includes a guide rail 22, a moving part 23 and a drive assembly 21. The guide rail 22 extends along a first direction. The steering control assembly 1 is connected to the moving part 23. The drive assembly 21 is used to drive the moving part 23 to move along the guide rail 22 so that the steering control assembly 1 can switch between an exhibition position and a storage position.

[0061] In this way, when the drive assembly 21 drives the moving part 23 to move along the guide rail 22, the moving part 23 drives the steering control assembly 1 to switch between the display position and the storage position, resulting in a simple structure and reduced size of the steering control device 10. Taking a vehicle as an example, when the drive assembly 21 drives the moving part 23 to move along the guide rail 22 towards the rear of the vehicle, the storage drive device 2 drives the steering control assembly 1 to switch from the storage position to the display position. When the drive assembly 21 drives the moving part 23 to move along the guide rail 22 towards the front of the vehicle, the storage drive device 2 drives the steering control assembly 1 to switch from the display position to the storage position.

[0062] For example, the drive component 21 can be an electric drive component, a pneumatic drive component, etc.

[0063] For example, the movable component 23 can be a ball block slider, a friction slider, etc. The movable component 23 can be connected to the steering control component 1 by means of bolts or other connecting parts, or it can be connected to the steering control component 1 by welding. In this embodiment, the specific connection method between the movable component 23 and the steering control component 1 is not limited.

[0064] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The steering control assembly 1 also includes a hand-feed motor 12 and a steering wheel 13. The hand-feed motor 12 is connected to one end of the central assembly 11, and the steering wheel 13 is connected to the other end of the central assembly 11.

[0065] For example, the steering control assembly also includes an angle detection element connected to the central assembly 11 for detecting the rotation angle of the steering wheel 13. The vehicle 100 controls the steering of the vehicle accordingly based on the rotation angle of the steering wheel 13 detected by the angle detection element.

[0066] In the above scheme, the central component 11, the hand-feel motor 12, and the angle detection component are combined to form a steer-by-wire device. This device eliminates the mechanical transmission structure between the steering wheel and the wheels. The controller intelligently controls the vehicle steering according to the rotation angle of the steering wheel 13, reducing the volume of the steering control device 10 and thus increasing the space of the cockpit.

[0067] In some examples, the center assembly 11 includes a steering column 14 and a connecting shaft passing through the steering column 14. The connecting shaft is rotatably connected to the steering column 14, with one end connected to the hand-feed motor 12 and the other end connected to the steering wheel 13. When the user turns the steering wheel 13, the connecting shaft rotates with the steering wheel 13, while the steering column 14 remains fixed relative to the steering wheel 13. When the retractable drive device 2 drives the steering control assembly 1 to the retracted position, the center assembly 11 moves as a whole along a first direction.

[0068] In other examples, the center assembly 11 includes a steering column 14, one end of which is connected to the steering wheel 13 and the other end to the handgrip motor 12. When the user turns the steering wheel 13, the steering column 14 rotates along with the steering wheel 13.

[0069] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The center assembly 11 includes a steering column 14, which connects the steering wheel 13 and the hand-feed motor 12. The steering column 14 can obscure the components between the steering wheel 13 and the hand-feed motor 12, improving the aesthetics of the steering control assembly 1. For example, the center assembly 11 also includes a toggle switch 16, located on the side of the steering column 14, for controlling functions such as windshield wipers or lights on the vehicle 100.

[0070] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The central component 11 includes a connecting shaft that connects the steering wheel 13 and the hand-feed motor 12 and rotates with the steering wheel 13 so that the hand-feed motor 12 provides hand-feed feedback through the connecting shaft and the steering wheel 13.

[0071] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The central component 11 includes a steering wheel 13, which is used by the user to steer the vehicle 100. The steering wheel 13 can have a circular, elliptical, square, or irregular geometric shape.

[0072] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The central assembly 11 includes an airbag 15, which has one end of the central assembly 11 facing the driver's seat 30. The airbag 15 is used to deploy in the event of a vehicle collision to cushion the impact between the user and the vehicle 100.

[0073] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The steering control device 10 also includes a pitch drive device 3, which drives the steering control assembly 1 to move along the height direction of the vehicle 100. In this way, the user can independently adjust the height position of the steering wheel 13 of the steering control assembly 1 according to their own driving habits or height adjustment, etc.

[0074] In some examples, the pitch drive 3 can be a manual drive. For example, when the steering control device 10 is rotatably connected to the dashboard, the user drives the steering control device 10 to move relative to the dashboard along the height direction of the vehicle 100 via the pitch drive 3, thereby realizing the movement of the steering control component 1 along the height direction of the vehicle 100.

[0075] In other examples, the pitch drive 3 can be an electrically driven device. For example, the pitch drive 3 includes a rotary motor, with a central assembly 11 extending radially along the rotary motor and connected to the output end of the rotary motor. When the rotary motor rotates, it drives the central assembly 11 to rotate along the central axis of the rotary motor, thereby enabling the steering control assembly 1 to move along the height direction of the vehicle 100.

[0076] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The pitch drive device 3 is connected to the steering control assembly 1, and the housing drive device 2 is connected to the pitch drive device 3. In this way, the integration of the steering control device 10 can be improved, thereby reducing the size of the steering control device 10.

[0077] In some examples, the storage drive 2 includes a drive assembly 21 and a moving part 23, a pitch drive 3 is connected to the moving part 23, and a steering control assembly 1 is connected to the pitch drive 3.

[0078] In other examples, the pitch drive 3 forms a movable part 23 that houses the drive 2, and the drive assembly 21 that houses the drive 2 directly drives the pitch drive 3 to move in a first direction.

[0079] In some examples, the steering control device 10 includes a controller 4 for controlling the pitch drive 3 and the retraction drive 2 according to user input instructions to adjust the position of the steering control assembly 1.

[0080] This application also provides an instrument panel assembly 20, please refer to... Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 The dashboard assembly 20 includes the steering control device 10 as described in any of the above embodiments. Because the arrangement of the steering control component 1 and the storage drive device 2 in the steering control device 10 reduces the length of the central component 11, the space occupied by the central component 11 in the height direction of the vehicle 100 is reduced. When the steering wheel 13 is within a preset height range, the height of components such as the storage drive device 2 connected to the central component 11 can be increased, thereby increasing the foot space under the dashboard assembly 20.

[0081] In some examples, the dashboard assembly 20 includes a tubular beam to which the steering control device 10 is connected. The steering control device 10 includes a mounting plate 17 and a mounting bracket 18, arranged along the longitudinal direction of the vehicle 100, both serving to connect to the tubular beam. Exemplarily, the mounting plate 17 is rotatably connected to other parts of the steering control device 10 via a pivot 19, allowing the steering control device 10 to rotate relative to the mounting plate 17 along the pivot 19, thereby adjusting the position of the steering wheel 13.

[0082] In some implementations, please refer to Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 The instrument panel assembly 20 also includes a lower guard plate 51, which has a through hole 51b. When the steering control component 1 is in the extended position, the steering control component 1 passes through the through hole 51b. The lower guard plate 51 has a lower edge 51a.

[0083] Along the height direction of the vehicle 100, the steering control assembly 1 of the steering control device 10 is located above the lower edge 51a of the lower guard plate 51. It should be noted that the lower guard plate 51 refers to the instrument panel 5 with a through hole 51b passing through the steering control assembly 1 when the steering control assembly 1 is in the displayed position, and at least a portion of the instrument panel 5 is located below the steering control assembly 1. Unless otherwise specified, the term "lower guard plate 51" in this application refers to the lower guard plate 51 described above. The lower edge 51a of the lower guard plate 51 refers to the lower edge of the lower guard plate 51 along the height direction of the vehicle 100 described above.

[0084] However, in some examples, the lower guard plate 51 may extend along the height direction of the vehicle 100 toward the underside of the dashboard assembly 20, forming a protective plate under the dashboard assembly 20. In this case, the lower edge 51a of the lower guard plate 51 refers to the edge of the lower contour of the lower guard plate 51 that can be seen by the driver's eyes when the user is sitting in the driver's seat 30 and in a driving posture.

[0085] In related technologies, at least a portion of the steering control assembly 1 is located below the lower edge 51a of the lower guard plate 51 along the height direction of the vehicle 100, encroaching on the foot space of the driver's cabin and affecting the comfort of the user. In this embodiment, the steering control assembly 1 is positioned above the lower edge 51a of the lower guard plate 51, thereby increasing the height of the lower surface of the instrument panel assembly 20 and increasing the foot space of the driver's cabin.

[0086] Especially when the driver's seat 30 is in a reclined position, the user's feet are positioned higher than when the driver's seat 30 is in a seated position, thus requiring more foot space under the dashboard assembly 20. Along the height of the vehicle 100, the lower edge 51a of the underbody protection plate 51 is typically higher than the upper surface of the seat cushion 8a of the driver's seat 30. When the steering control assembly 1 is positioned above the lower edge 51a, the foot space under the dashboard assembly 20 is increased along the height of the vehicle 100.

[0087] For example, the lower guard plate 51 can be a flat plate structure, or the lower guard plate 51 can be a curved surface structure, etc.

[0088] In some implementations, please refer to Figure 15 and Figure 17Along the height direction of the vehicle 100, the distance A between the lower edge 51a and the floor 40 of the driver's cabin of the vehicle 100 satisfies the following conditions: when the vehicle 100 is a sedan, A satisfies: 360mm ≤ A ≤ 450mm; when the vehicle 100 is a sport utility vehicle, A satisfies: 410mm ≤ A ≤ 480mm. Since the steering control assembly 1 is located above the lower edge 51a, sufficient foot space is formed below the dashboard assembly 20 along the height direction of the vehicle 100, improving the comfort of the driver's cabin.

[0089] In some examples, when the vehicle 100 is a car, the vehicle can be specifically distinguished as a sedan or a sport utility vehicle (SUV). The sport utility vehicle is a four-wheel drive off-road vehicle that integrates off-road, storage, travel, and towing functions; it is a combination of an off-road vehicle and a station wagon, also known as an SUV. Because the cabin space varies between different vehicle models, the distance A between the lower edge 51a of the underbody protection plate 51 and the floor 40 of the cabin can be specifically set for each model to increase legroom.

[0090] For example, in the case of a passenger car, the distance A between the lower edge 51a and the floor 40 of the passenger compartment can be 360mm, 370mm, 380mm, 410mm, 450mm, etc. In related technologies, the distance between the lower edge 51a of the lower guard plate 51 and the floor 40 of the passenger compartment in passenger cars is usually around 318mm. In this embodiment, the distance between the lower edge 51a and the floor 40 of the passenger compartment is optimized to about 42mm, which significantly increases the foot space in the passenger compartment.

[0091] For example, in a sport utility vehicle (SUV) model, the distance A between the lower edge 51a and the floor 40 of the passenger compartment can be 410mm, 430mm, 450mm, 460mm, 480mm, etc. In related technologies, the distance between the lower edge 51a and the floor 40 of the passenger compartment in a sport utility vehicle model is typically between 300mm and 330mm. In this embodiment, the distance between the lower edge 51a and the floor 40 of the passenger compartment is optimized to at least 80mm, significantly increasing the legroom in the passenger compartment.

[0092] In some implementations, please refer to Figure 15 and Figure 17 The driver's seat 30 of the vehicle 100 has a lower limit position for its seat cushion 8a. The lower limit position of the seat cushion 8a of the driver's seat 30 refers to the position where the distance between the upper surface of the seat cushion 8a and the floor 40 of the driver's cabin is minimized when the seat cushion 8a is adjusted along the height direction of the vehicle 100. At this time, the position of the seat cushion 8a is the lower limit position.

[0093] Along the height direction of the vehicle 100, the lower edge 51a is located above the seat cushion 8a at the lower limit position, and the distance between the lower edge 51a and the seat cushion 8a at the lower limit position is E. When the vehicle 100 is a sedan, E satisfies: 110mm ≤ E. Alternatively, when the vehicle 100 is a sport utility vehicle, E satisfies: 75mm ≤ E ≤ 95mm. Thus, when the driver's seat 30 is in a reclined position, there is ample legroom between the seat cushion 8a of the driver's seat 30 and the dashboard assembly 20 along the height direction of the vehicle 100.

[0094] In some examples, when the vehicle 100 is a car, the vehicle can be specifically distinguished as a sedan or a sport utility vehicle. Since the cabin space varies between different vehicle models, the distance between the lower edge 51a of the lower guard plate 51 and the seat cushion 8a at the lower limit position along the vehicle height direction can be specifically set for each vehicle model to improve lower limb space.

[0095] For example, for a sedan, the distance E between the lower edge 51a and the seat cushion 8a at the lower limit position along the height direction of the vehicle can be 110mm, 120mm, 130mm, 140mm, 150mm, etc. In related technologies, the distance between the lower edge 51a of the lower guard plate 51 and the seat cushion 8a at the lower limit position along the height direction of the vehicle in a sedan is usually around 50mm. In this embodiment, the distance between the lower edge 51a and the seat cushion 8a at the lower limit position is optimized to more than 60mm, which significantly increases the distance between the lower edge 51a of the lower guard plate 51 and the seat cushion 8a of the driver's seat 30 along the height direction of the vehicle.

[0096] For example, in a sport utility vehicle (SSUV) model, the distance E between the lower edge 51a and the seat cushion 8a at the lower limit position can be 75mm, 80mm, 85mm, 90mm, 95mm, etc. In related technologies, the lower edge 51a of the lower guard plate 51 in a sport utility vehicle model is usually located below the upper surface of the seat cushion 8a at the lower limit position. In this embodiment, the lower edge 51a is located above the upper surface of the seat cushion 8a, which significantly increases the distance between the lower edge 51a of the lower guard plate 51 and the seat cushion 8a of the driver's seat 30 along the vehicle height direction.

[0097] In some implementations, please refer to Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 20 The dashboard assembly 20 also includes a first protective plate 6, which is located between its lower edge 51a and the front bulkhead 9 of the vehicle 100. The steering control assembly 1 is located above the first protective plate 6 along the height direction of the vehicle 100.

[0098] In related technologies, components such as the steering column 14 of the steering control assembly 1 are inclined, at least a portion of the steering control assembly 1 passes through the first protective plate 6, and an opening needs to be provided in the front bulkhead 9 of the vehicle. The steering control assembly 1 further passes through the opening in the front bulkhead 9 and is connected to the actuator for transmission. As a result, the steering control assembly 1 occupies the space below the first protective plate 6, affecting the comfort of the driver's seat.

[0099] In the above scheme, along the vehicle height direction, the surface of the first protective plate 6 forms the surface of the dashboard assembly 20 facing the floor 40 of the driver's cabin, that is, the space between the first protective plate 6 and the floor 40 of the driver's cabin forms the foot space of the driver's cabin. Since the steering control assembly 1 is located above the lower edge 51a, when the steering control assembly 1 is also located above the first protective plate 6, the height of the first protective plate 6 can be the same as or similar to the height of the lower edge 51a along the height direction of the vehicle 100, which can significantly increase the foot space of the driver's cabin.

[0100] In some examples, the first protective plate 6 extends horizontally.

[0101] In other examples, the first protective plate 6 intersects with the front-rear direction of the vehicle 100.

[0102] In some examples, along the front-rear direction of the vehicle 100, one end of the first protective plate 6 is connected to the lower edge 51a of the lower guard plate 51, and the other end is connected to the front bulkhead 9.

[0103] In other examples, the lower edge 51a of the lower guard plate 51 extends toward the front enclosure 9 to form the first protective plate 6.

[0104] In some implementations, see Figure 14 , Figure 15 , Figure 16 and Figure 17 The first protective plate 6 extends along the front-rear direction of the vehicle 100. The space below the first protective plate 6 forms the foot space of the driver's cabin. When the first protective plate 6 extends along the front-rear direction of the vehicle 100, a connecting space is formed below the first protective plate 6 towards the driver's seat 30, thereby increasing the foot space in the front-rear direction of the vehicle 100.

[0105] In some examples, the first protective plate 6 extends horizontally along the front-rear direction of the vehicle 100.

[0106] In other examples, the first protective plate 6 is inclined along the longitudinal direction of the vehicle 100. For example, the height of the first protective plate 6 gradually increases along the direction from the dashboard assembly 20 to the driver's seat 30; or, the height of the first protective plate 6 gradually decreases along the direction from the dashboard assembly 20 to the driver's seat 30.

[0107] In some implementations, please refer to Figure 15 and Figure 17 The angle F between the first protective plate 6 and the vehicle 100 in the front-rear direction satisfies: 0°≤F≤30°. Since the angle F between the first protective plate 6 and the vehicle 100 in the front-rear direction is within the range of 0° to 30°, the overall height of the first protective plate 6 along the front-rear direction of the vehicle 100 is similar to the lower edge 51a, which increases the overall space under the dashboard assembly 20 and improves the foot space and adaptability to users of different heights.

[0108] In some examples, the angle F between the first protective plate 6 and the traffic vehicle 100 in the front-rear direction can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, etc.

[0109] In some examples, the extension direction of the first protective plate 6 is parallel to the front-rear direction of the vehicle 100.

[0110] In other examples, along the direction from the dashboard assembly 20 toward the driver's seat 30, the first protective plate 6 gradually tilts upward.

[0111] In some other examples, the first protective plate 6 gradually tilts downwards along the direction from the dashboard assembly 20 toward the driver's seat 30.

[0112] It should be noted that "tilting upward" and "tilting downward" are relative to the height of the vehicle 100.

[0113] In some implementations, please refer to Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 The first protective plate 6 intersects with the lower protective plate 51. In this way, the first protective plate 6 and the lower protective plate 51 can cooperate to prevent foreign objects from entering the instrument panel assembly 20 and enhance the protection performance of the instrument panel assembly 20.

[0114] In some examples, the first protective plate 6 and the lower protective plate 51 can be an integral structure. For example, the lower edge 51a of the lower protective plate 51 extends in the direction of the front enclosure 9 to form the first protective plate 6; or, the first protective plate 6 and the lower protective plate 51 can be separate structures.

[0115] In some implementations, please refer to Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 The angle between the first protective plate 6 and the lower protective plate 51 is G, where G satisfies: 180° < G < 270°. The angle F between the first protective plate 6 and the lower protective plate 51 is between 180° and 270°, which can increase the space of the cockpit. Specifically, the intersection of the first protective plate 6 and the lower protective plate 51 is usually below the steering control assembly 1. Along the longitudinal direction of the vehicle 100, the angle between the central assembly 11 and the drive housing 2 is usually between 180° and 270°. The angle between the first protective plate 6 and the lower protective plate 51 is the same as or similar to the angle between the central assembly 11 and the drive housing 2, which can reduce the gap between the first protective plate 6, the lower protective plate 51 and the steering control assembly 10, thereby maximizing the space of the cockpit.

[0116] In some examples, the included angle G between the first protective plate 6 and the lower protective plate 51 can be 190°, 200°, 230°, 260°, 265°, etc.

[0117] In some implementations, please refer to Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 At least a portion of the first protective plate 6 is movable to open or close the lower opening of the instrument panel assembly 20. In this way, after the movable portion of the first protective plate 6 is moved, the first protective plate 6 forms an opening, allowing for the maintenance and repair of components inside the instrument panel assembly 20, thus improving the convenience of maintenance and repair operations.

[0118] In some examples, the first protective plate 6 includes a first protective plate 6 body and a movable protective plate, wherein the first protective plate 6 body has an opening, and when the movable protective plate closes the opening, the movable protective plate is connected to the opening position of the first protective plate 6 body; when the movable protective plate opens the opening, the movable protective plate is offset to one side of the opening or removed from the first protective plate 6 body.

[0119] For example, the movable guard plate is connected to the body of the first protective plate 6 by screws.

[0120] For example, the movable guard plate is slidably connected to the body of the first protective plate 6. For instance, one of the body of the first protective plate 6 and the movable guard plate is provided with a groove, and the other is provided with a slider, which is slidably connected to the groove.

[0121] In some implementations, please refer to Figure 13 , Figure 14 and Figure 15The dashboard assembly 20 also includes a second protection plate 7, which is connected between the first protection plate 6 and the front panel 9 of the vehicle 100, and the second protection plate 7 intersects with the first protection plate 6.

[0122] When a second protective plate 7 is disposed between the first protective plate 6 and the front bulkhead 9, and the second protective plate 7 extends in a different direction than the first protective plate 6, the angle between the second protective plate 7 and the first protective plate 6 can improve the flexibility of the lower limb space arrangement.

[0123] Specifically, since the dashboard assembly 20 contains numerous components, and these components may have irregular shapes, a second protective plate 7 can be installed at locations where the first protective plate 6 interferes with the components. The extension direction of the second protective plate 7 will allow for clearance of the components. For example, the second protective plate 7 can be used to avoid obstructing the drive motor of the drive unit 2. Alternatively, if there is unused space inside the dashboard assembly 20, the extension direction of the second protective plate 7 can create legroom in the driver's cabin. In this way, the second protective plate 7, in conjunction with the first protective plate 6, maximizes the lower limb space in the driver's cabin.

[0124] In some examples, the second protective plate 7 gradually moves away from the floor 40 of the cockpit in a direction away from the first protective plate 6. This increases the foot space of the vehicle 100 near the front bulkhead 9.

[0125] In other examples, the second protective plate 7 gradually approaches the floor 40 of the cockpit in a direction away from the first protective plate 6. At this time, a clearance space can be formed above the second protective plate 7 to facilitate the arrangement of internal components of the instrument panel assembly 20.

[0126] In some examples, the second protective plate 7 is a flat plate structure, or the second protective plate 7 is an arc-shaped structure.

[0127] In some implementations, please refer to Figure 13 , Figure 14 and Figure 15 The angle between the second protective plate 7 and the first protective plate 6 is B, where B satisfies: 90° < B < 180°. When the angle B between the second protective plate 7 and the first protective plate 6 is between 90° and 180°, the second protective plate 7 tilts towards the floor 40 of the cockpit from the direction of the first protective plate 6 pointing towards the front bulkhead 9, thus creating a clearance space above the second protective plate 7.

[0128] In some examples, the angle B between the second protective plate 7 and the first protective plate 6 can be 91°, 100°, 130°, 150°, 175°, etc.

[0129] This application also provides a vehicle 100, including the steering control device 10 in any of the above embodiments, or the dashboard assembly 20 in any of the above embodiments.

[0130] In some embodiments, the vehicle 100 may be a vehicle, such as an electric vehicle, a fuel vehicle, a hybrid electric vehicle, etc.

[0131] For example, the vehicle may include a smart cockpit, or a smart driving system, or be adapted to a smart connected system.

[0132] Among them, the transportation vehicle 100 can be a vehicle, or it can be a ship, an airplane, etc.

[0133] In some implementations, see Figure 18 and Figure 19 It also includes a driver's seat 30, which includes a leg rest 8c. The driver's seat 30 has a reclining mode. When the driver's seat 30 is in the reclining mode, the leg rest 8c is located below the lower edge 51a of the lower guard plate 51.

[0134] For example, the driver's seat 30 also includes a seat cushion 8a and a backrest 8b. Along the longitudinal direction of the vehicle 100, the leg rest 8c is located in front of the seat cushion 8a, and the backrest 8b is located behind the seat cushion 8a. When the driver's seat 30 is in a reclined mode, the tilt angle of the backrest 8b relative to the seat cushion 8a increases, making the surface of the backrest 8b parallel or nearly parallel to the surface of the seat cushion 8a, and the leg rest 8c unfolds relative to the seat cushion 8a to support the user's feet or legs.

[0135] For example, the reclining mode can be as follows: When the vehicle is parked, the backrest 8b can be adjusted backward along the vehicle's fore-and-aft direction to form an angle M of 165° to 175° with the upper surface of the seat cushion 8a. At the same time, the leg rest 8c extends forward from the driver's seat 30, with the leg rest 8c forming an angle N of 157° to 175° with the upper surface of the seat cushion 8a. In this state, due to the extension of the leg rest 8c, the user's feet will naturally rise, significantly increasing the need for foot space. Due to height limitations, the lower guard plate 51 of the traditional dashboard assembly 20 is prone to interfering with the user's feet when they are raised, making it impossible to design the leg rest 8c or affecting the comfort of the reclining mode.

[0136] In this embodiment, the steering control device 10 raises the height of the lower edge 51a of the lower guard plate 51 in the dashboard assembly 20. When the driver's seat 30 is in a reclining mode, the leg rest 8c is located below the lower edge 51a of the lower guard plate 51, which increases the space above the leg rest 8c.

[0137] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0138] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
