[0035] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0036] This application provides a vehicle. The specific type of vehicle is not specifically limited in this application; for example, the vehicle provided in this application can be an electric vehicle, a hybrid vehicle, a gasoline vehicle, or a solar-powered vehicle. It is understood that an electric vehicle is powered by an electric motor and also has a battery connected to the motor to supply power; a hybrid vehicle may include a gasoline engine and an electric motor, which can simultaneously or alternately power the vehicle; a gasoline vehicle includes a gasoline engine and a transmission, with the gasoline engine providing power to the vehicle through the transmission; and a solar-powered vehicle utilizes solar energy to generate electricity, which is then used to power the vehicle via an electric motor.

[0037] The vehicle provided in this application embodiment can also be a vehicle of different types. For example, the vehicle provided in this application embodiment can be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV), etc.

[0038] In some embodiments, see Figure 1 The vehicle in this application includes a body-in-white 101, wheels and a suspension system. The wheels are connected to the body-in-white 101 through the suspension system. The body-in-white 101 is arranged to form a driver's cab 103 and a passenger cabin 104. The driver is located in the driver's cab 103 and other occupants can be located in the passenger cabin 104.

[0039] In the above implementation, the vehicle also includes a seat 102, which can be installed in the driver's cab 103 and / or passenger cabin 104. A reasonable positioning of the seat 102 on the body-in-white 101 ensures optimal comfort.

[0040] In some embodiments, see Figure 1 and combined Figure 2 and Figure 3 The seat 102 includes a frame 4 and a seat cushion bracket 5. The frame 4 is used for mounting on the body-in-white 101. The seat cushion bracket 5 is slidably connected to the frame 4, and the sliding direction of the seat cushion bracket 5 is parallel to the lateral direction of the vehicle. The seat 102 also includes a seat cushion and a backrest. The seat cushion is mounted on the seat cushion bracket and is approximately parallel to the horizontal plane. The backrest is erected at the rear end of the seat cushion and is connected to the seat cushion bracket. When the driver or other passengers are riding, they sit on the seat cushion and lean against the backrest to ensure riding comfort.

[0041] In one possible implementation, the frame 4 may have a longitudinal slide rail 1 and a transverse slide rail 2. The frame 4 is connected to the body-in-white 101 via the longitudinal slide rail 1 to allow the frame 4 to slide longitudinally along the vehicle. The seat support 5 is connected to the frame 4 via the transverse slide rail 2 to allow the seat support 5 to slide laterally along the vehicle.

[0042] In some examples, the longitudinal slide rail 1 may include a first sliding bracket and a second sliding bracket. The first sliding bracket is connected to the body-in-white 101. The first sliding bracket is provided with a first groove extending along the vehicle busbar. A first limiting groove is provided on the wall of the first groove. A portion of the second sliding bracket slides within the first groove. The second sliding bracket is provided with a first limiting block, which slides within the first limiting groove. The second sliding bracket is connected to the frame. By sliding the second sliding bracket within the groove, the frame can move in the longitudinal direction. Simultaneously, the first limiting block, sliding within the first limiting groove, prevents the second sliding bracket from separating from the first sliding bracket in both the vertical longitudinal and transverse directions.

[0043] In some examples, the transverse slide rail 2 may include a third sliding bracket and a fourth sliding bracket. The third sliding bracket is connected to the frame and has a second slide groove extending in the transverse direction of the vehicle. A second limiting groove is provided on the wall of the second slide groove. A portion of the fourth sliding bracket slides within the second slide groove. The fourth sliding bracket has a second limiting block that slides within the second limiting groove. The fourth sliding bracket is connected to the seat cushion bracket. By sliding the fourth sliding bracket within the second slide groove, the seat cushion bracket can move in the transverse direction. Simultaneously, the second limiting block, sliding within the second limiting groove, prevents the fourth sliding bracket from separating from the third sliding bracket in both the vertical longitudinal direction and the transverse direction.

[0044] In some embodiments, see Figure 2 and combined Figure 1 and Figure 4 The seat 102 also includes a first drive mechanism, which is connected to the body-in-white 101 and the frame 4. The first drive mechanism can drive the frame to move in the longitudinal direction. For example, the first drive mechanism may include a first drive motor, a first screw, and a first nut. The first nut is disposed on the frame, the first screw engages with the first nut, and the first screw is drively connected to the first drive motor. The centerline of the first screw is parallel to the longitudinal direction. During operation, the first drive motor drives the first screw to rotate, which in turn drives the frame to move in the longitudinal direction via the first nut, thereby adjusting the position of the seat in the longitudinal direction.

[0045] In some embodiments, the seat 102 further includes a second drive mechanism connected to the seat cushion support 5 and the frame 4. The second drive mechanism can drive the seat cushion support to move in the lateral direction. For example, the second drive mechanism may include a second drive motor, a second screw, and a second nut. The second nut is disposed on the seat cushion support, the second screw engages with the second nut, and the second screw is drively connected to the second drive motor. The centerline of the second screw is parallel to the lateral direction. During operation, the second drive motor drives the second screw to rotate, which in turn drives the seat cushion support to move in the lateral direction via the second nut, thereby adjusting the position of the seat in the lateral direction.

[0046] The seat 102 provided in this embodiment of the application also includes a roller blind device 3, which is disposed at one end of the seat cushion support 5 in the lateral direction. The roller blind device 3 includes a rotating shaft 6, a curtain body 8, and a driving device 15. The rotating shaft 6 is rotatably connected to the frame 4. One end of the curtain body 8 is connected to the rotating shaft 6 and is wound around the rotating shaft 6. The other end of the curtain body 8 is connected to the seat cushion support 5. The driving device 15 is connected to the rotating shaft 6 in a transmission manner. The driving device 15 is used to drive the rotating shaft 6 to rotate when the seat cushion support 5 slides to the initial position, so that the curtain body 8 gradually wraps around the rotating shaft 6.

[0047] In this embodiment of the seat 102, during lateral adjustment, the seat cushion support 5 moves laterally from its initial position. Simultaneously, the seat cushion support 5 pulls the other end of the curtain 8, causing it to gradually unwrap from the rotating shaft 6. The unwrapped curtain covers the gap created by the movement of the seat cushion support 5. As the seat cushion support moves laterally back to its initial position, the gap gradually decreases, and the driving device 15 drives the rotating shaft 6 to rotate, causing the curtain 8 to gradually wrap around the rotating shaft 6, thus achieving the roll-up of the curtain 8. The initial position can be the position where the seat cushion support 5 is not moving laterally.

[0048] The seat provided in this embodiment has a frame 4 mounted on a white body 101. A seat cushion bracket 5 is used to mount the seat cushion, and the seat cushion bracket 5 is slidably connected to the frame 4 so that the seat cushion bracket 5 can slide relative to the frame 4 in the lateral direction of the vehicle. A roller blind device 3 is disposed at one end of the seat cushion bracket 5 in the lateral direction. The roller blind device 3 includes a rotating shaft 6, a curtain 8, and a driving device 15. The rotating shaft 6 is rotatably connected to the frame 4. One end of the curtain 8 is connected to the rotating shaft 6 and is wound around the rotating shaft 6. The other end of the curtain 8 is connected to the seat cushion bracket 5. The driving device 15 is drively connected to the rotating shaft 6 and is used to drive the rotating shaft 6 to rotate when the seat cushion bracket 5 slides to the initial position, so that the curtain 8 gradually wraps around the rotating shaft 6. As the seat cushion support 5 moves away from its initial position in the lateral direction, the seat cushion support 5 pulls the other end of the curtain 8 so that the curtain 8 gradually unwraps itself from the pivot 6. The unwrapped curtain 8 covers the gap formed by the movement of the seat cushion support 5, thereby preventing debris from falling into the gap.

[0049] On the other hand, as the seat cushion support 5 moves laterally toward its initial position, the gap formed by the movement of the seat cushion support 5 gradually decreases, and the drive device 15 drives the rotating shaft 6 to rotate, so that the curtain 8 gradually wraps around the rotating shaft 6, thereby realizing the winding of the curtain 8.

[0050] In some embodiments, see Figure 2 and combined Figure 4 When the seat cushion support 5 moves away from its initial position in the lateral direction, the drive device 15 can also drive the rotating shaft 6 to rotate, so that the curtain 8 gradually unwraps itself and covers the gap formed by the movement of the seat cushion support 5.

[0051] In other embodiments, when the seat cushion support 5 moves away from the initial position in the lateral direction, the drive device 15 may not work. At this time, the seat cushion support 5 pulls the rotating shaft 6 to rotate, so that the curtain 8 gradually unwinds.

[0052] It is understandable that the speed at which the drive shaft device drives the rotating shaft 6 is set reasonably so that the speed at which the curtain 8 moves is approximately the same as the speed at which the cushion support 5 moves, thereby reducing the stress on the curtain 8 and increasing its service life.

[0053] In some embodiments, see Figure 2 and combined Figure 4 The drive device 15 includes a motor 50, a first gear 51, and a second gear 52. The first gear is driven by the main shaft of the motor 50, and the second gear 52 is driven by the rotating shaft 6. The first gear 51 and the second gear 52 mesh. For example, the motor 50 can be mounted on the frame 4. Correspondingly, the first gear 51 can be mounted on the main shaft of the motor 50, and the second gear 52 can be mounted on the rotating shaft 6. The first gear 51 and the second gear 52 mesh to drive the rotating shaft 6 to rotate via the motor 50.

[0054] With the above settings, the motor 50 drives the rotating shaft 6 to rotate through the first gear 51 and the second gear 52. The transmission ratio is fixed and precise, ensuring that the speed of the motor 50 and the speed of the rotating shaft 6 are in a stable proportional relationship. This ensures that the speed at which the curtain 8 moves is approximately the same as the speed at which the cushion support 5 moves, thereby reducing the force on the curtain 8.

[0055] In the above implementation, the number of teeth of the first gear 51 can be less than the number of teeth of the second gear 52, so that the rotating shaft 6 can obtain a larger driving torque.

[0056] In some embodiments, see Figure 4 The drive device 15 includes a motor 50, a transmission belt, a first pulley, and a second pulley. The first pulley is driven by the main shaft of the motor, and the second pulley is driven by the rotating shaft 6. The transmission belt cooperates with the first and second pulleys. For example, the first pulley can be mounted on the main shaft of the motor 50, and the second pulley can be mounted on the rotating shaft 6.

[0057] For example, the drive belt is elastic, which can absorb the impact force when the motor starts / stops, reducing mechanical vibration and noise. In addition, when there is a difference between the moving speed of the curtain 8 and the moving speed of the seat support 5, the drive belt slips with the first pulley and / or the second pulley, thereby preventing the curtain 8 from being subjected to excessive force.

[0058] In some embodiments, see Figure 2 and combined Figure 4The roller shutter device 3 also includes a first mounting frame 9, a second mounting frame 10, a first fixed shaft 11, and a second fixed shaft 12. Both the first mounting frame 9 and the second mounting frame 10 are connected to the frame body 4. The first fixed shaft 11 is connected to the first mounting frame 9, and the second fixed shaft 12 is connected to the second mounting frame 10. One end of the rotating shaft 6 is rotatably connected to the first fixed shaft 11, and the other end of the rotating shaft 6 is rotatably connected to the second fixed shaft 12.

[0059] In one possible implementation, the rotating shaft 6 can be connected to the first fixed shaft 11 and the second fixed shaft 12 by bearings to reduce the rotational resistance of the rotating shaft 6.

[0060] In some embodiments, see Figure 4 The rotating shaft 6 has an internal receiving channel, with the first fixed shaft 11 passing through one end of the receiving channel and the second fixed shaft 12 passing through the other end of the receiving channel.

[0061] For example, bearings can be fitted onto the first fixed shaft 11 and the second fixed shaft 12, with bearing mounting grooves accommodating the channels, to achieve a rotatable connection between the rotating shaft and the first fixed shaft 11 and the second fixed shaft 12.

[0062] In one possible implementation, the first fixed shaft 11 and the second fixed shaft 12 are inserted from both ends of the receiving channel to forcibly constrain the axial movement of the rotating shaft, so as to ensure the stability of the connection between the first fixed shaft 11 and the first mounting bracket 9, and the second fixed shaft 12 and the second mounting bracket 10.

[0063] In some embodiments, see Figure 4 The second mounting bracket 10 has a mounting groove 100 at one end, and a baffle 20 is provided at the end of the second fixed shaft 12. The second fixed shaft 12 is engaged in the mounting groove 100, and the baffle 20 abuts against the end of the second mounting bracket 10 away from the first mounting bracket 9. With this configuration, the mounting groove 100 has an open end, and the second fixed shaft 12 can be engaged into the mounting groove 100 through the open end, which facilitates the disassembly and installation of the second fixed shaft 12.

[0064] In one possible implementation, the mounting groove 100 is disposed on one end of the second mounting bracket 10 perpendicular to the second fixed shaft 12. The second fixed shaft 12 is snapped into the mounting groove 100 in a snap-fit ​​manner, which serves to position the second mounting bracket 10 and the second fixed shaft 12. The baffle 20 abuts against the end of the second mounting bracket 10 away from the first mounting bracket 9, which serves to limit the second mounting bracket 10 and the second fixed shaft 12 and ensure the stability of their assembly.

[0065] In some embodiments, see Figure 2 and combined Figure 4The second mounting bracket 10 is provided with a locking hole, and the baffle 20 is provided with a locking part, which is locked in the locking hole. With this configuration, the locking part is locked in the locking hole, which can prevent the second fixed shaft 12 from moving out of the opening of the mounting groove 100, so as to ensure the connection stability.

[0066] In one possible implementation, the locking hole is located directly below the mounting groove 100, and the locking part is located directly below the baffle, with the locking part engaging within the locking hole. For example, the locking hole can be an elongated hole, and the shape of the locking part matches the shape of the locking hole, guiding the baffle 20 to quickly align with the mounting position of the second mounting bracket 10, avoiding manual adjustment deviations and improving assembly efficiency.

[0067] In some embodiments, see Figure 4 and combined Figure 2 The other end of the curtain 8 is detachably connected to the seat cushion bracket 5.

[0068] With this configuration, the other end of the curtain 8 can be detachably connected to the seat cushion bracket 5, making it easy to install and remove.

[0069] In some embodiments, see Figure 2 and combined Figure 4 The other end of the curtain body 8 is provided with a first connecting plate 81, which is attached to the curtain body 8. The end of the first connecting plate 81 is provided with a second connecting plate 82, which is perpendicular to the first connecting plate 81. The second connecting plate 82 is detachably connected to the seat cushion bracket 5.

[0070] In one possible implementation, the second connecting plate 82 and the first connecting plate 81 form an "L"-shaped rigid structure. For example, the other end of the curtain 8 is provided with a plurality of "L"-shaped structures formed by the second connecting plate 82 and the first connecting plate 81, and they are evenly distributed on the other end of the curtain 8, which solves the problems of easy shaking and poor adaptability of traditional planar connections.

[0071] For example, each of the second connecting plates 82 can be connected to the seat cushion bracket 5 by means of bolts or snap-fit.

[0072] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope 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.
