Description

Technical Field

[0001] This application relates to the field of vehicle-mounted projection equipment technology, specifically to a screen assembly, a cockpit and its control method, and a vehicle. Background Technology

[0002] With the development of vehicle technology, it has become possible to install screens in vehicle cabins. However, current screens used in vehicles suffer from structural instability. Summary of the Invention

[0003] This application provides a screen assembly, a cockpit, a control method thereof, and a vehicle. The screen assembly is installed on the ceiling of the cockpit and includes a roller, a projection screen, and a drive rope. The drive rope drives both ends of one side of the projection screen to move simultaneously, providing stable traction for the unfolding and rewinding of the projection screen, thereby providing structural support for the projection screen and improving its structural stability.

[0004] In a first aspect, this application provides a screen assembly. The screen assembly is for installation on the ceiling of a cockpit and includes a roller, a screen drive, a projection screen, a first elastic element, a first drive rope, and a second drive rope. The roller is installed on the ceiling. The screen drive is installed on the ceiling and is drively connected to the roller. The projection screen is wound on the roller along a first winding direction. The first elastic element is installed at the end of the projection screen away from the roller and is in a tensioned state. A first end of the first drive rope is wound on the roller along a second winding direction, and a second end of the first drive rope is fixedly connected to the first end of the first elastic element; the second winding direction is opposite to the first winding direction. A first end of the second drive rope is wound on the roller along the second winding direction, and the first end of the second drive rope and the first end of the first drive rope are located on opposite sides of the projection screen; the second end of the second drive rope is fixedly connected to the second end of the first elastic element.

[0005] In this application, the first and second drive ropes are designed to wind in opposite directions on the reel to the projection screen, so that when the reel unfolds the projection screen, the first and second drive ropes can be wound up, thereby stretching the first elastic element. This results in a greater tension force exerted by the first elastic element on the projection screen, ensuring that the projection screen is in a taut state and thus guaranteeing the stability and surface flatness of the projection screen during the unfolding process.

[0006] In this application, since the first drive rope and the second drive rope are fixedly connected to the two ends of the first elastic member, the force on the projection screen at both ends on the side away from the roller tends to be consistent, which is conducive to the force balance on the left and right sides of the projection screen, thereby improving the stability of the projection screen during the unfolding and rewinding process.

[0007] In some possible implementations, the first elastic element has a first tension force when the projection screen is unfolded, and a second tension force when the projection screen is rolled up, with the first tension force being greater than the second tension force.

[0008] In this implementation, the design of the first elastic element ensures that the tension force exerted by the first elastic element on the projection screen is directly proportional to the unfolded size of the projection screen, thereby ensuring that the projection screen remains in a taut state during unfolding and rewinding, which is beneficial to the movement stability of the projection screen.

[0009] In some possible implementations, the screen assembly also includes a first fixed pulley and a second fixed pulley. The first and second fixed pulleys are fixed to the end of the projection screen away from the roller and are located on both sides of the first elastic member in the length direction. The first drive rope is wound around the first fixed pulley, and the second drive rope is wound around the second fixed pulley.

[0010] In this implementation, the design of the first and second fixed pulleys provides support and guidance for the first and second drive ropes, respectively. This reduces the degree of bending of the first drive rope near the first elastic member and the second drive rope near the second elastic member, thereby reducing stress concentration in the first and second drive ropes and facilitating better force transmission. Furthermore, it prevents the first and second drive ropes from rubbing against the projection screen.

[0011] In some possible implementations, the screen assembly also includes a third and a fourth fixed pulley, both fixed to the ceiling and located on either side of the projection screen. A first drive rope is wound around the third fixed pulley, and a second drive rope is wound around the fourth fixed pulley.

[0012] In this implementation, the design of the third and fourth fixed pulleys can provide support and guidance for the first and second drive ropes respectively, so as to avoid the first drive rope and the second drive rope from rubbing against the projection screen in the part near the roller.

[0013] In some possible implementations, the cockpit also includes two side pillars connected to the two sides of the ceiling, positioned opposite each other, with the curtain assembly located between the two side pillars. The curtain assembly also includes a fifth and a sixth fixed pulley, which are respectively mounted on the two side pillars. A first drive rope is wound around the fifth fixed pulley, and a second drive rope is wound around the sixth fixed pulley.

[0014] In this implementation, the design of the fifth and sixth fixed pulleys can provide support and guidance for the first and second drive ropes, respectively, thereby improving the stability of the first and second drive ropes during the unfolding and rewinding of the projection screen.

[0015] In some possible implementations, the screen assembly also includes a fixing tube fixed to the end of the projection screen away from the roller, with the first elastic element located inside the fixing tube.

[0016] In this implementation, the design of the fixing tube provides support and protection for the first elastic element, allowing it to be better installed at the end of the projection screen to prevent the first elastic element from shifting position.

[0017] Secondly, this application also provides a cockpit. The cockpit includes a ceiling and a curtain assembly as described in any of the first aspects, the curtain assembly being mounted on the ceiling.

[0018] In this application, the design of the screen assembly improves the stability of the projection screen during unfolding and retracting, thereby enhancing the user experience in the cockpit.

[0019] In some possible implementations, the cockpit also includes two side pillars and two partition assemblies. The two side pillars are connected to both sides of the ceiling and are positioned opposite each other, with the screen assembly located between the two side pillars. The two partition assemblies are movably mounted on the two side pillars respectively, and have a retracted state and an extended state. In the retracted state, the partition assembly is at least partially housed within the side pillar, and in the extended state, the partition assembly extends at least partially beyond the side pillar, allowing the projection screen to slide smoothly connected to the partition assembly.

[0020] In this implementation, by designing partition components, the projection screen, after being unfolded, provides a visual barrier along with the screen itself, thus separating the front and rear seats of the cabin and improving the quietness of the rear seats. The partition components also provide a sliding track for the projection screen, ensuring that the screen is supported by the partition components on both sides during roll-up and roll-down, thereby improving the stability of the screen during these processes. Furthermore, when the projection screen is fully unfolded, the partition components on both sides also provide structural support, improving the stability of the screen during projection and enhancing its resistance to bumps and vibrations during cabin movement, thus improving the user experience.

[0021] In this implementation, the partition component is designed to be movably installed in the side pillar so that when the projection screen is not in use, the partition component can be at least partially housed in the side pillar, thereby reducing the space occupied by the side pillar and preventing the partition component from protruding too much from the side pillar and appearing obtrusive. This reduces the visual interference in the cabin after the projection screen is rolled up, and helps to improve the visibility of the rear seats in the cabin.

[0022] In some possible implementations, the partition assembly includes a first guide rail, and the screen assembly includes two first sliders connected to both sides of the projection screen. In the unfolded state, the first sliders can move along the first guide rail, and the two first sliders correspond one-to-one with the two first guide rails.

[0023] In this implementation, the cooperation between the first guide rail and the first slider can improve the stability of the sliding connection between the projection screen and the second partition, which is beneficial to improving the stability of the projection screen during unfolding and rewinding.

[0024] In some possible implementations, the first guide rail includes a connecting section and a track body. The connecting section is connected to the end of the track body near the ceiling. The shape of the connecting section is different from that of the track body. In the unfolded state, the first slider can slide into the track body through the connecting section.

[0025] In this implementation, the design of the connecting section provides a structural transition for the first slider to slide into the main body of the track, which helps the first slider to slide into the main body of the track more stably, thereby improving the stability of the projection screen unfolding.

[0026] In some possible implementations, the end of the connecting segment away from the main track body has a first opening, and the end of the connecting segment connected to the main track body has a second opening, with the size of the first opening being larger than the size of the second opening.

[0027] In this implementation, the size of the first opening is designed to be larger than that of the second opening, so that in the unfolded state, it is easier to align the first slider with the connecting section, thereby facilitating the stable sliding of the first slider into the connecting section and into the track body, thus improving the stability of the projection screen unfolding.

[0028] In some possible implementations, the curtain device further includes a second guide rail fixed to the ceiling. In the retracted state, the first slider is located on the second guide rail. In the extended state, at least a portion of the second guide rail is located within the first opening.

[0029] In this implementation, the design of the second guide rail ensures that the first slider can be stably housed within it in the retracted state, preventing it from shifting and thus guaranteeing the stability of the projection screen. Furthermore, in the unfolded state, the second guide rail provides motion support for the first slider, allowing it to slide more stably into the connecting section and further into the main track body.

[0030] In some possible implementations, the first guide rail is rotatably connected to the side column, and the connecting section is used to avoid the first slider during the movement of the first guide rail. That is, the connecting section is used to avoid the first slider during the rotation of the second partition around the first rotation center, so as to prevent the first slider from shifting during the unfolding and retraction of the partition assembly, thereby ensuring the stability of the projection screen.

[0031] In some possible implementations, the connecting section has an arc-shaped structure, with the bending direction pointing towards the rotation center of the first guide rail. In the retracted state, the first slider is located in the connecting section. In the extended state, the first slider can slide to connect with the main track body.

[0032] In this implementation, by designing the connecting segment to have an arc-shaped structure, it is beneficial for the connecting segment to avoid the first slider during its rotation around the first rotation center.

[0033] In some possible implementations, the bending center of the connecting segment is the rotation center of the first guide rail. This design ensures that the first slider is located on the movement path of the connecting segment. When the first guide rail moves, the first slider remains fixed, and the connecting segment slides with the first slider without causing the first slider to deflect.

[0034] Thirdly, this application provides a cockpit control method. The cockpit includes a ceiling, two side pillars, two partition assemblies, and a screen assembly as described in any of the first aspects. The two side pillars are connected to both sides of the ceiling and are positioned opposite each other. The screen assembly is located between the two side pillars and installed on the ceiling. The two partition assemblies are movably installed on the two side pillars respectively. The partition assemblies have a retracted state and an extended state. In the retracted state, the partition assemblies are at least partially housed within the side pillars. In the extended state, the partition assemblies extend at least partially beyond the side pillars. When the partition assemblies are in the retracted state and the projection screen is rolled up, the method includes: extending the partition assemblies to the extended state; and extending the projection screen. When the partition assemblies are in the extended state and the projection screen is unfolded, the method includes: rolling up the projection screen; and retracting the partition assemblies to the retracted state.

[0035] In this application, by first unfolding the partition assembly and then the projection screen, the partition assembly provides a sliding guide for the projection screen, thereby improving the stability of the projection screen's unfolding. During the rewinding process of the projection screen, the partition assembly provides a sliding guide for the projection screen, thereby improving the stability of the projection screen's rewinding.

[0036] Fourthly, this application provides a control device. The control device includes at least one processor coupled to at least one memory for executing computer instructions stored in the memory to cause the control device to perform the method as described in the third aspect.

[0037] Fifthly, this application provides a chip or chip system. The chip or chip system includes at least one processing circuit for running a computer program, causing the chip or chip system to perform the method as described in the third aspect.

[0038] Sixthly, this application provides a computer-readable storage medium. The computer-readable storage medium stores a computer program or instructions that, when executed on a computer, cause the computer to perform the method as described in the third aspect.

[0039] In a seventh aspect, this application provides a computer program product. When the computer program product is run on a computer, it causes the computer to perform the method as described in the third aspect.

[0040] Eighthly, this application provides a means of transportation. The means of transportation includes a curtain assembly as described in any of the first aspects; or, includes a cabin as described in any of the second aspects.

[0041] In this application, the design of the screen assembly improves the stability of the projection screen's unfolding and retraction, thereby enhancing the user experience of the vehicle. Attached Figure Description

[0043] The embodiments of this application are described below with reference to the accompanying drawings.

Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0048] Please refer to the following: Figure 1A and Figure 1B , Figure 1A This is a schematic diagram of a vehicle 100 provided in one embodiment of this application in some embodiments; Figure 1B yes Figure 1A The diagram shows the curtain assembly 3 in some embodiments of the vehicle 100.

[0049] In some embodiments, the vehicle 100 can be a vehicle, rail vehicle, ship, aircraft, etc. The vehicle can be, but is not limited to, a sedan, multi-purpose vehicle (MPV), sport / suburban utility vehicle (SUV), off-road vehicle (ORV), pickup truck, van, bus, truck, etc. Figure 1A and Figure 1B In this embodiment, the vehicle 100 is described as an example. Of course, other types of vehicles 100 can also adopt a similar structure, which will not be described in detail below.

[0050] It should be noted that, Figure 1A and Figure 1B The diagram only illustrates a portion of the structure of the vehicle 100. In other embodiments, the vehicle 100 may include more or fewer structures, which is not limited here.

[0051] In some embodiments, the vehicle 100 may include a cabin 10. For example, when the vehicle 100 is a vehicle, the cabin 10 may include the front cabin 10 and / or the rear cabin 10 of the vehicle.

[0052] For example, the cockpit 10 may include a ceiling 1 and two side pillars 2, which are connected to both sides of the ceiling 1 and are positioned opposite each other. A screen assembly 3 may be installed in the cockpit 10. The screen assembly 3 may be fixed to the ceiling 1 of the cockpit 10 and located between the two side pillars 2. The screen assembly 3 may be used for projection for audio-visual entertainment and may also be used to isolate the cockpit 10 for privacy protection.

[0053] The screen assembly 3 may include a projection screen 31, which is used for projection to provide audio-visual entertainment.

[0054] The screen assembly 3 can roll up or unfold the projection screen 31.

[0055] Please see Figure 1A The projection screen 31 is rolled up by the screen assembly 3. The screen assembly 3 is located in the ceiling 1. At this time, the front and rear rows of the cabin 10 have a connected view.

[0056] Please see Figure 1B The screen assembly 3 unfolds the projection screen 31, which unfolds vertically and blocks part of the view between the front and rear rows in the cabin 10, thus providing a certain degree of privacy protection. The projection screen 31 can also be used for projection for entertainment.

[0057] Next, we will introduce how to roll up and unfold the projection screen 31.

[0058] Please see Figure 2 , Figure 2 yes Figure 1A The diagram shows a partial structural schematic of the cabin 10 in some embodiments of the vehicle 100.

[0059] In some embodiments, the screen assembly 3 may further include a roller 32, a screen drive 33, a first elastic element 34, a first drive rope 35, and a second drive rope 36. The roller 32 is mounted on the ceiling 1. The screen drive 33 may be mounted on the ceiling 1 and is drively connected to the roller 32. The projection screen 31 may be wound around the roller 32 along a first winding direction. The first elastic element 34 may be mounted on the end of the projection screen 31 away from the roller 32, and the first elastic element 34 is in a tensioned state. The first end 351 of the first drive rope 35 may be wound around the roller 32 along a second winding direction, and the second end 352 of the first drive rope 35 may be fixedly connected to the first end 341 of the first elastic element 34, the second winding direction being opposite to the first winding direction. The first end 361 of the second drive rope 36 can be wound around the roller 32 along the second winding direction. The first end 361 of the second drive rope 36 and the first end of the drive rope are located on both sides of the projection screen 31. The second end 362 of the second drive rope 36 can be fixedly connected to the second end 342 of the first elastic member 34.

[0060] In this embodiment, the winding directions of the first drive rope 35 and the second drive rope 36 on the roller 32 are opposite to the winding direction of the projection screen 31 on the roller 32. This allows the first drive rope 35 and the second drive rope 36 to be wound up when the roller 32 unfolds the projection screen 31, thereby stretching the first elastic member 34. This results in a greater tension force exerted by the first elastic member 34 on the projection screen 31, ensuring that the projection screen 31 is in a taut state and thus guaranteeing the stability and surface flatness of the projection screen 31 during the unfolding process.

[0061] In this embodiment, since the first drive rope 35 and the second drive rope 36 are fixedly connected to the two ends of the first elastic member 34, the force on the projection screen 31 on the side away from the roller 32 tends to be consistent at both ends, which is beneficial to the force balance on the left and right sides of the projection screen 31, thereby improving the stability of the projection screen 31 during the unfolding and rewinding process.

[0062] For example, when the projection screen 31 is unfolded, the first elastic member 34 may have a first tension force, and when the projection screen 31 is rolled up, the first elastic member 34 may have a second tension force, and the first tension force is greater than the second tension force.

[0063] In this embodiment, the design of the first elastic element 34 ensures that the tension force exerted by the first elastic element 34 on the projection screen 31 is directly proportional to the unfolded size of the projection screen 31, thereby ensuring that the projection screen 31 remains in a taut state during unfolding and rewinding, which is beneficial to the movement stability of the projection screen 31.

[0064] The screen assembly 3 may also include a fixing tube 37, which is fixed to the end of the projection screen 31 away from the roller 32, and the first elastic member 34 is located inside the fixing tube 37.

[0065] In this embodiment, the design of the fixing tube 37 can provide support and protection for the first elastic member 34, so that the first elastic member 34 can be better installed at the end of the projection screen 31 to avoid the first elastic member 34 from shifting position.

[0066] For example, the screen assembly 3 may also include a first fixed pulley 381 and a second fixed pulley 382. The first fixed pulley 381 and the second fixed pulley 382 may be fixed to the end of the projection screen 31 away from the roller 32 and located on both sides of the first elastic member 34 in the length direction. The first drive rope 35 is wound around the first fixed pulley 381, and the second drive rope 36 is wound around the second fixed pulley 382.

[0067] In this embodiment, the design of the first fixed pulley 381 and the second fixed pulley 382 provides support and guidance for the first drive rope 35 and the second drive rope 36, respectively. This reduces the degree of bending of the first drive rope 35 near the first end 341 of the first elastic member 34 and the second drive rope 36 near the second end 342 of the first elastic member 34, thereby reducing stress concentration in the first drive rope 35 and the second drive rope 36 and facilitating better force transmission between them. Furthermore, it also prevents the first drive rope 35 and the second drive rope 36 from rubbing against the projection screen 31.

[0068] For example, the screen assembly 3 also includes a third fixed pulley 383 and a fourth fixed pulley 384, both of which are fixed to the ceiling 1 and located on both sides of the projection screen 31. A first drive rope 35 is wound around the third fixed pulley 383, and a second drive rope 36 is wound around the fourth fixed pulley 384.

[0069] In this embodiment, the design of the third fixed pulley 383 and the fourth fixed pulley 384 can provide support and guidance for the first drive rope 35 and the second drive rope 36 respectively, so as to avoid the first drive rope 35 and the second drive rope 36 from rubbing against the projection screen 31 in the part near the roller 32.

[0070] For example, the curtain assembly 3 may also include a fifth fixed pulley 385 and a sixth fixed pulley 386, which are respectively installed on two side columns 2. A first drive rope 35 is wound around the fifth fixed pulley 385, and a second drive rope 36 is wound around the sixth fixed pulley 386.

[0071] In this embodiment, the design of the fifth fixed pulley 385 and the sixth fixed pulley 386 can provide support and guidance for the first drive rope 35 and the second drive rope 36 respectively, thereby improving the stability of the first drive rope 35 and the second drive rope 36 during the unfolding and rewinding of the projection screen 31.

[0072] It should be noted that, Figure 2 The illustrated curtain assembly 3 includes a first fixed pulley 381, a second fixed pulley 382, ​​a third fixed pulley 383, a fourth fixed pulley 384, a fifth fixed pulley 385, and a sixth fixed pulley 386. In some other embodiments, the curtain assembly 3 may also include more or fewer fixed pulleys.

[0073] Please refer to the following: Figure 3A and Figure 3B , Figure 3A yes Figure 2 A schematic diagram of the projection screen 31 unfolded from the screen assembly 3 shown; Figure 3B yes Figure 2 The diagram shows the projection screen 31 being rolled up by the screen assembly 3. It should be noted that... Figure 3A and Figure 3B The straight line with an arrow indicates the direction of the force on the drive rope, which is also the direction of the drive rope's motion.

[0074] Please see Figure 3A As the scroll 32 unfolds the projection screen 31, it winds up the first drive rope 35 and the second drive rope 36. This causes the portion of the first drive rope 35 between the third fixed pulley 383 and the fifth fixed pulley 385 to move upward, thereby causing the portion of the first drive rope 35 between the fifth fixed pulley 385 and the first fixed pulley 381 to move downward. This, in turn, causes the portion of the first drive rope 35 between the first fixed pulley 381 and the first end 341 of the first elastic member 34 to move to the left, thus stretching the first elastic member 34. Simultaneously, the portion of the second drive rope 36 between the fourth fixed pulley 384 and the sixth fixed pulley 386 moves upward, thereby causing the portion of the second drive rope 36 between the sixth fixed pulley 386 and the second fixed pulley 382 to move downward. This, in turn, causes the portion of the second drive rope 36 between the second fixed pulley 382 and the second end 342 of the first elastic member 34 to move to the right, thus stretching the first elastic member 34. This causes both sides of the first elastic element 34 to be stretched simultaneously, increasing the tension of the first elastic element 34. During this process, the more the projection screen 31 is unfolded, the more first drive ropes 35 and second drive ropes 36 are wound up by the roller 32, resulting in a longer stretch of the first elastic element 34, and thus a greater tension of the first elastic element 34 on the projection screen 31.

[0075] Please see Figure 3B When the roller 32 retracts the projection screen 31, the roller 32 releases the first drive rope 35 and the second drive rope 36. The first elastic element 34 returns to its original shape. The first elastic element 34 pulls the portion of the first drive rope 35 located between the first end 341 of the first elastic element 34 and the first fixed pulley 381 to move to the right, thereby causing the portion of the first drive rope 35 located between the first fixed pulley 381 and the fifth fixed pulley 385 to move upward. This causes the portion of the first drive rope 35 located between the fifth fixed pulley 385 and the third fixed pulley 383 to move downward, thus keeping the first drive rope 35 taut. Simultaneously, the first elastic element 34 pulls the portion of the second drive rope 36 located between the second end 342 of the first elastic element 34 and the second fixed pulley 382 to move to the left, thereby causing the portion of the second drive rope 36 located between the second fixed pulley 382 and the sixth fixed pulley 386 to move upward, thereby causing the portion of the second drive rope 36 located between the sixth fixed pulley 386 and the fourth fixed pulley 384 to move downward, thus keeping the second drive rope 36 taut.

[0076] The design of the partition component 4 will be introduced next.

[0077] Please refer to the following: Figure 4A and Figure 4B , Figure 4A yes Figure 1A A partial structural schematic diagram of the cabin 10 in some embodiments of the vehicle 100 shown; Figure 4B yes Figure 4A A schematic diagram of the projection screen 31 unfolded in the screen assembly 3 in the cockpit 10 shown.

[0078] In some embodiments, the cockpit 10 may also include two partition components 4, which may be installed on the side pillars 2, with each partition component 4 corresponding to one of the two side pillars 2.

[0079] In this embodiment, by designing the partition component 4, it can work together with the projection screen 31 to provide isolation and block the line of sight after the projection screen 31 is unfolded, thereby separating the front and rear rows of the cabin 10 and improving the quietness of the rear row of the cabin 10.

[0080] For example, the projection screen 31 can be slidably connected to the partition component 4.

[0081] In this embodiment, the partition components 4 provide a sliding track for the projection screen 31, ensuring that the projection screen 31 is supported by the partition components 4 on both sides during its roll-up and roll-out, thereby improving the stability of the projection screen 31 during roll-up and roll-out. Furthermore, after the projection screen 31 is fully unfolded, the partition components 4 on both sides also provide structural support, improving the stability of the projection screen 31 during projection and enhancing its resistance to bumps and vibrations during cockpit 10 movement, thus improving the user experience of the projection screen 31.

[0082] When the vehicle 100 is a car, the side pillar 2 is the B-pillar. It should be noted that the B-pillar specifically refers to the support pillar between the front door and the rear of the vehicle, as well as the overall structure of the exterior trim that surrounds the support pillar.

[0083] The partition component 4 can be slidably connected to the projection screen 31 through a slider rail or magnetic attraction.

[0084] In some other embodiments, the projection screen 31 may not be connected to the partition component 4. After the projection screen 31 is unfolded, the side of the projection screen 31 and the partition component 4 may overlap to improve the effect of separating the front and rear rows of the cabin 10 after the projection screen 31 is unfolded, thereby improving the quietness of the rear row of the cabin 10.

[0085] Please refer to the following: Figure 5A and Figure 5B , Figure 5A yes Figure 1A A partial structural schematic diagram of the cabin 10 in some other embodiments of the vehicle 100 shown; Figure 5B yes Figure 5A The diagram shows the partition assembly 4 in the cockpit 10 retracting to the side pillar 2 in some embodiments.

[0086] In some embodiments, the partition assembly 4 can be movably mounted on the side column 2. The partition assembly 4 has a retracted state and an extended state. In the retracted state, the partition assembly 4 can be at least partially housed within the side column 2. In the extended state, the partition assembly 4 can at least partially extend out of the side column 2. The projection screen 31 can be slidably connected to the partition assembly 4.

[0087] In this embodiment, the partition component 4 is designed to be movably installed on the side pillar 2 so that when the projection screen 31 is not used, the partition component 4 can be at least partially housed in the side pillar 2, thereby reducing the space occupied by the side pillar 2 and preventing the partition component 4 from protruding too much from the side pillar 2 and appearing obtrusive. This reduces the visual interference of the cabin 10 after the projection screen 31 is rolled up, which is beneficial to improving the rear visibility of the cabin 10.

[0088] In some examples, the cockpit 10 may also include a front seat 5 located behind the curtain assembly 3. The front seat 5 is spaced apart from the side pillars 2 along the arrangement direction of the two side pillars 2. The front seat 5 has a first direction of movement D1, which intersects with the arrangement direction of the two side pillars 2. In the retracted state, a portion of the partition assembly 4 extends out of the side pillars 2 along the first direction of movement D1, and the portion of the partition assembly 4 extending out of the side pillars 2 is offset from the front seat 5.

[0089] In this embodiment, by designing the size of the partition component 4 extending out of the side pillar 2 in the unfolded state, the partition component 4 can be retracted into the side pillar 2 when the projection screen 31 is not needed, so as to provide space for the front seat 5 to move towards the rear. This avoids the partition component 4 obstructing the movement of the front seat 5. With this design, the front seat 5 can move to the rear, recline, and lie flat without any movement obstruction, thus improving the user experience of the cabin 10.

[0090] It should be noted that, Figure 5BThe diagram illustrates the first direction of movement, D1, perpendicular to the plane of the paper, which is the direction from the front row of the cabin 10 to the rear row. Understandably, when the backrest of the front seat 5 rotates towards the rear row of the cabin 10, the first direction of movement, D1, refers to the direction of rotation using the pivot of the front seat 5's backrest as the axis of rotation. At this time, along the first direction of movement, D1, the portion of the partition assembly 4 extending from the side pillar 2 is offset from the front seat 5. This means that along the movement path of the front seat 5's backrest, the partition assembly 4 is offset from the front seat 5. In other words, at each rotation point of the front seat 5's backrest, along the tangent of that rotation point, the portion of the partition assembly 4 extending from the side pillar 2 is offset from the front seat 5.

[0091] In other examples, in the retracted state, the partition assembly 4 can be entirely located within the side pillar 2.

[0092] In this embodiment, since the partition assembly 4 can be completely located within the side pillar 2 in the retracted state, the exterior of the side pillar 2 no longer has an obtrusive design, optimizing its appearance. Simultaneously, the rear passenger view of the cabin 10 becomes more unobstructed, improving the rear passenger experience. Furthermore, because the side pillar 2 does not protrude, the movement of the front seats 5 towards the rear is no longer hindered, enhancing the front passenger experience.

[0093] For example, the partition assembly 4 can be electrically controlled to move relative to the side pillar 2, or the partition assembly 4 can be manually controlled to move relative to the side pillar 2.

[0094] The partition component 4 can rotate, translate, or combine rotation and translation relative to the side column 2 to achieve the conversion between the retracted state and the deployed state.

[0095] For example, the partition assembly 4 is movably installed on the side pillar 2. The partition assembly 4 can be directly movably connected to the side pillar 2, or the partition assembly 4 can be movably connected to the roof 1 to form an indirect movable connection with the side pillar 2.

[0096] Please refer to the following: Figure 6A and Figure 6B , Figure 6A yes Figure 1A A partial structural schematic diagram of the cabin 10 in some embodiments of the vehicle 100 shown; Figure 6B yes Figure 6A The diagram shows the partition assembly 4 in the cockpit 10 in some embodiments in an deployed state.

[0097] In some embodiments, the partition assembly 4 may include a first partition 41 and a second partition 42, both of which are movably connected to the side column 2. The first partition 41 and the second partition 42 are at least partially overlapped. In the retracted state, both the first partition 41 and the second partition 42 are at least partially housed within the side column 2. In the extended state, both the first partition 41 and the second partition 42 extend at least partially from the side column 2, with the second partition 42 closer to the other side column 2 than the first partition 41, and the projection screen 31 is slidably connected to the second partition 42.

[0098] In this embodiment, by designing the first partition 41 and the second partition 42, the partitions are made into secondary movable parts. In the retracted state, this allows the partition assembly 4 to be more fully accommodated within the side pillar 2, thereby reducing the protrusion of the partition assembly 4 from the side pillar 2. This is both aesthetically pleasing and avoids obstructing the movement of the front seats 5 in the cabin 10. In the unfolded state, the partition assembly 4 unfolds with a smaller width to form a wider shape, allowing the second partition 42 to slide against the projection screen 31.

[0099] It should be noted that in the vehicle 100, especially in a vehicle, the overall size of the side pillar 2 is limited, resulting in limited space for the side pillar 2 to accommodate the partition assembly 4. Since the partition assembly 4 needs to ensure sliding cooperation with the projection screen 31 when extended and avoid obstructing the rearward movement of the front seat 5 when retracted, if the partition assembly 4 only includes one partition member, it is difficult to simultaneously meet the requirements of the partition assembly 4 in both extended and retracted states. However, in this embodiment, by designing the partition assembly 4 to include a first partition member 41 and a second partition member 42, with at least partial overlap between the first partition member 41 and the second partition member 42, the requirements of the partition assembly 4 in both extended and retracted states can be simultaneously met by adjusting the overlap area of ​​the first partition member 41 and the second partition member 42 in both extended and retracted states.

[0100] For example, in the retracted state, the first partition 41 and the second partition 42 have a first overlapping area, and in the unfolded state, the first partition 41 and the second partition 42 have a second overlapping area, the second overlapping area being smaller than the first overlapping area.

[0101] In this embodiment, in the retracted state, the first partition 41 and the second partition 42 have a larger overlap area, which facilitates the inclusion of more of the first partition 41 and the second partition 42 within the side pillar 2, thereby reducing or even eliminating the protrusion of the partition assembly 4 relative to the side pillar 2. This reduces the abruptness of the side pillar 2, improves the visibility of the rear seats in the cabin 10, and also avoids obstructing the rearward movement of the front seats 5. In the unfolded state, the first partition 41 and the second partition 42 have a smaller overlap area, so that the overall size of the first partition 41 and the second partition 42 is larger than in the retracted state in the arrangement direction of the two side pillars 2. This facilitates the sliding engagement between the second partition 42 and the projection screen 31. Therefore, by designing the overlap area of ​​the first partition 41 and the second partition 42, the limited space of the side pillar 2 can be fully utilized to achieve more inclusion and avoid obstructing the rearward movement of the front seats 5. It can also be unfolded to form a larger overall size to achieve a sliding engagement with the projection screen 31.

[0102] It should be noted that the second overlapping area can be 0, in which case the first partition 41 and the second partition 42 can form a larger overall size.

[0103] For example, the first partition 41 and the second partition 42 can both be rotatably connected to the side post 2. The movement is simple and facilitates the quick housing of the first partition 41 and the second partition 42 into the side post 2 and their quick extension out of the side post 2.

[0104] The first partition 41 and the second partition 42 can be rotatably connected to the side post 2 through the same rotating member. This design is beneficial for simultaneously controlling the rotation of the first partition 41 and the second partition 42 relative to the side post 2.

[0105] In some other embodiments, the first partition 41 and the second partition 42 can also be rotatably connected to the side pillar 2 through different rotating parts, as long as the partition assembly 4 can not obstruct the front seat 5 from moving backward in the retracted state, and the partition assembly 4 can be slidably connected to the projection screen 31 in the unfolded state.

[0106] Please continue reading. Figure 6B For example, in the unfolded state, part of the first partition 41 can be located inside the side post 2. On the one hand, this allows the side post 2 to provide some support for the first partition 41, and on the other hand, it can reduce the gap between the side post 2 and the first partition 41, which is beneficial to improving the overall aesthetics of the side post 2 and the partition assembly 4 in the unfolded state.

[0107] In the unfolded state, there is no gap between the first partition 41 and the side pillar 2 along the arrangement direction of the two side pillars 2. In other words, along the arrangement direction of the two side pillars 2, the side of the first partition 41 away from the second partition 42 is located inside the side pillar 2. This design makes there no gap between the first partition 41 and the side pillar 2 everywhere, which helps to reduce the abruptness of the side pillar 2 and the first partition 41 in the unfolded state and optimizes the overall appearance.

[0108] Please continue reading. Figure 6A and Figure 6B For example, along the arrangement direction of the two side pillars 2, there can be no gap between the first partition 41 and the second partition 42. In other words, along the arrangement direction of the two side pillars 2, the side of the second partition 42 near the side pillar 2 overlaps with the first partition 41. This design makes there no gap between the first partition 41 and the second partition 42 everywhere, which helps to reduce the overall abruptness of the first partition 41 and the second partition 42 and optimize the overall appearance.

[0109] In some embodiments, at least a portion of the second partition 42 is located on the back side of the first partition 41, such that along the arrangement direction of the two side posts 2, the side of the second partition 42 closest to the side post 2 can be located on the back side of the first partition 41, that is, the first partition 41 can form a shielding of the inner side of the second partition 42 to eliminate visual abruptness and improve the overall aesthetics of the first partition 41 and the second partition 42.

[0110] For example, in the retracted state, along the direction of the second partition 42 pointing to the other side post 2, the second partition 42 may not exceed the first partition 41, so that the first partition 41 can form a shielding on the outer side of the second partition 42, thereby eliminating the visual abruptness and improving the overall aesthetics of the first partition 41 and the second partition 42.

[0111] In some embodiments, the cockpit 10 may further include a first limiting member (not shown) and a second limiting member (not shown), the first limiting member being mounted on the second partition 42 and the second limiting member being mounted on the canopy 1. In the deployed state, the first limiting member abuts against the second limiting member.

[0112] In this embodiment, the design of the first limiting member and the second limiting member can limit the movement of the partition component 4 during its unfolding process, so as to avoid excessive movement of the partition component 4. This allows the partition component 4 to stop unfolding more accurately at a preset position, so that the projection screen 31 and the second partition component 42 can form a sliding connection.

[0113] In some examples, the first limiting member can be a separate structure, and the first limiting member is fixedly connected to the second partition member 42, and / or the second limiting member can be a separate structure, and the second limiting member is fixedly connected to the canopy 1.

[0114] In other examples, the first limiting member can be the structure of the second partition 42 itself, and / or the second limiting member can be the structure of the canopy 1 itself, so that the interior of the cabin 10 can utilize its own structural design to achieve motion limitation.

[0115] It should be noted that the specific shape and size of the first and second limiting members are not limited, as long as they can limit the unfolding of the partition component 4 so that the projection screen 31 can form a sliding connection with the second partition component 42.

[0116] Next, we will introduce the sliding connection design between the curtain assembly 3 and the partition assembly 4.

[0117] Please refer to the following: Figure 7A and Figure 7B , Figure 7A yes Figure 2 A schematic diagram of the structure of the first guide rail 44 of the partition assembly 4 in the cockpit 10 shown in some embodiments; Figure 7B yes Figure 7A The diagram shown is a schematic of the first guide rail 44 in an unfolded state in some embodiments.

[0118] In some embodiments, the partition assembly 4 may further include a first guide rail 44, which is mounted on the side of the second partition 42 facing the other side post 2. The screen assembly 3 may further include two first sliders 40, which can be connected to both sides of the projection screen 31. In the unfolded state, the first sliders 40 can move along the first guide rails 44, and the two first sliders 40 correspond one-to-one with the two first guide rails 44.

[0119] In this embodiment, the cooperation between the first guide rail 44 and the first slider 40 can improve the stability of the sliding connection between the projection screen 31 and the second partition 42, which is beneficial to improving the stability of the projection screen 31 during the unfolding and rewinding process.

[0120] For example, the first guide rail 44 may include a connecting section 441 and a track body 442. The connecting section 441 is connected to the end of the track body 442 near the ceiling 1. The shape of the connecting section 441 is different from that of the track body 442. In the unfolded state, the first slider 40 can slide into the track body 442 via the connecting section 441.

[0121] In this embodiment, the design of the connecting section 441 provides a structural transition for the first slider 40 to slide into the track body 442, which helps the first slider 40 to slide into the track body 442 more stably, thereby improving the stability of the projection screen 31 when unfolded.

[0122] The connecting section 441 is used to avoid the first slider 40 during the movement of the first guide rail 44. That is, the connecting section 441 is used to avoid the first slider 40 during the rotation of the second partition 42 around the first rotation center O1, so as to avoid the first slider 40 from shifting during the unfolding and retraction of the partition assembly 4, so as to ensure the stability of the projection screen 31.

[0123] The first guide rail 44 is rotatably connected to the side post 2, and the connecting section 441 has an arc-shaped structure, with the bending direction of the connecting section 441 pointing towards the rotation center of the first guide rail 44. In the retracted state, the first slider 40 is located at the connecting section 441, and in the unfolded state, the first slider 40 can slide to connect to the main track body 442.

[0124] In this embodiment, by designing the connecting segment 441 to have an arc-shaped structure, it is beneficial for the connecting segment 441 to avoid the first slider 40 during the rotation of the first rotation center O1.

[0125] The bending center of the connecting segment 441 can be the rotation center of the first guide rail 44, which is the first rotation center O1. This design ensures that the first slider 40 is located on the movement path of the connecting segment 441. When the first guide rail 44 moves, the first slider 40 can remain fixed. The connecting segment 441 and the first slider 40 slide, but the first slider 40 will not be offset.

[0126] Among them, the connecting section 441 can be a single-sided guide structure or a double-sided guide structure.

[0127] In some other embodiments, the connecting segment 441 can be a larger structure to allow for movement avoidance of the first slider 40.

[0128] Please refer to the following: Figure 8A and Figure 8B , Figure 8A yes Figure 2 A schematic diagram of the structure of the first guide rail 44 of the partition assembly 4 in the cockpit 10 shown in some other embodiments; Figure 8B yes Figure 8A The diagram shown is a schematic of the first guide rail 44 in an unfolded state in some embodiments.

[0129] In some embodiments, the end of the connecting segment 441 away from the track body 442 may have a first opening 4411, and the end of the connecting segment 441 connected to the track body 442 may have a second opening 4412, wherein the size of the first opening 4411 is larger than the size of the second opening 4412.

[0130] In this embodiment, by designing the size of the first opening 4411 to be larger than the size of the second opening 4412, it is easier to align the first slider 40 with the connecting section 441 in the unfolded state, thereby facilitating the stable sliding of the first slider 40 into the connecting section 441 and into the track body 442, thus improving the stability of the projection screen 31 when unfolded.

[0131] For example, the curtain device also includes a second guide rail 39, which is fixed to the ceiling 1. In the retracted state, the first slider 40 is located on the second guide rail 39; in the unfolded state, at least a portion of the second guide rail 39 is located within the first opening 4411.

[0132] In this embodiment, the design of the second guide rail 39 ensures that the first slider 40 can be stably housed within the second guide rail 39 in the retracted state, thereby preventing the first slider 40 from shifting and ensuring the stability of the projection screen 31. Furthermore, in the unfolded state, the second guide rail 39 provides motion support for the first slider 40, allowing it to slide more stably into the connecting section 441 and further into the track body 442.

[0133] The above describes the structural design of the partition assembly 4 and the curtain assembly 3 in some embodiments of the cockpit 10. Next, the control methods of the partition assembly 4 and the curtain assembly 3 in some embodiments of the cockpit 10 will be introduced.

[0134] Please see Figure 9 , Figure 9 This is a schematic diagram of a cockpit 10 control method provided in one embodiment of this application.

[0135] In some embodiments, the control method may include steps S10 to S40.

[0136] Step S10: Unfold the partition component 4 to the unfolded state.

[0137] Step S20: Unfold the projection screen 31.

[0138] In this embodiment, by first unfolding the partition component 4 and then unfolding the projection screen 31, the partition component 4 can provide a sliding guide for the projection screen 31, thereby improving the stability of the unfolding of the projection screen 31.

[0139] Step S30: Roll up the projection screen 31.

[0140] Step S40: Retract the partition component 4 to the retracted state.

[0141] In this embodiment, during the process of rolling up the projection screen 31, the partition component 4 can provide a sliding guide for the projection screen 31, thereby improving the stability of the roll-up of the projection screen 31.

[0142] In this embodiment, since the partition assembly 4 is in the retracted state, it can avoid the front seat 5, so that the front seat 5 will not structurally interfere with the partition assembly 4 during the rearward movement. The rearward movement of the front seat 5 includes the entire front seat 5 moving towards the rear of the cabin 10 and the backrest of the front seat 5 rotating towards the rear of the cabin 10.

[0143] It should be noted that the control method may include some of the steps S10 to S40. For example, the control method may include only steps S10 and S20, or the control method may include only steps S30 and S40.

[0144] It should be noted that the control method is not limited to the above order. For example, the control sequence of the control method can also be steps S30, S40, S10, and S20. Understandably, the specific control sequence of the control method depends on the specific states of the partition assembly 4 and the curtain assembly 3.

[0145] For example, the control method can also link the movement of the projection screen 31 and the partition assembly 4 with the movement of the front seat 5. Specifically, the control method may further include: responding to a command to move the front seat 5 backward; confirming whether the partition assembly 4 is in a retracted state; if so, moving the front seat 5 backward; if not, further confirming whether the projection screen 31 is rolled up; if so, retracting the partition assembly 4 to the retracted state; if not, first rolling up the projection screen 31, then retracting the partition assembly 4 to the retracted state.

[0146] For example, before unfolding the partition assembly 4 to the unfolded state, the control method may further include: responding to the partition assembly 4 unfolding command; confirming whether the front seat 5 needs to be moved forward; if so, moving the front seat 5 forward and then unfolding the partition assembly 4 to the unfolded state; if not, unfolding the partition assembly 4 to the unfolded state.

[0147] The execution and storage entities of the above control methods will be introduced next.

[0148] In some embodiments, the control device may include a unit for executing the control method described above, and each unit in the control device may be used to execute a corresponding process of the control method described above.

[0149] For example, the control device may include an acquisition unit and a processing unit. When the control device is used to execute the above control method, the acquisition unit may be used to acquire position information of the partition assembly and the curtain assembly, and the processing unit may be used to execute and control the partition assembly and the curtain drive component.

[0150] It should be understood that the division of units in the above device is only a logical functional division.
