Description

Technical Field

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

[0002] With advancements in vehicle technology, it has become possible to install screens in vehicle cabins. Currently, to improve rear passenger privacy, partition curtains are often installed in conjunction with screens to block the view between the driver's cabin and the rear passengers.

[0003] However, due to the limitations of the vehicle's design, the roller length of the partition curtain is limited, making it impossible to support the edges of the partition curtain. As a result, the edges of the partition curtain tend to sag when unfolded and collapse when rolled up. Utility Model Content

[0004] This application provides a curtain device, a cockpit, and a vehicle. The curtain device includes a curtain, a partition curtain, and a first reinforcing rib. The first reinforcing rib is disposed on the partition curtain to provide support for the partition curtain, thereby preventing the edges of the partition curtain from drooping when unfolded and from collapsing when rolled up.

[0005] In a first aspect, this application provides a curtain device. The curtain device includes a curtain, a partition curtain, a first roller, a second roller, and a first reinforcing rib. The curtain is connected to the first roller, which is used to roll up or unroll the curtain. The second roller is located on the back side of the curtain. The partition curtain includes a first part and a second part. The first part is connected between the second roller and the second part. Along the axial direction of the second roller, the width of the second part is greater than the width of the first part and greater than the length of the second roller. The second roller is used to roll up or unroll the partition curtain. The first reinforcing rib is disposed in the second part. The stiffness of the first reinforcing rib is greater than the stiffness of the second part. Along the axial direction of the second roller, the first reinforcing rib covers at least a portion of the second part.

[0006] In this application, since the lateral dimension of the overhead space in the cabin is typically smaller than that of the bottom space, the installation space provided for the curtain device is limited, making it difficult to make the second roller long. By designing the width of the second part to be greater than the width of the first part, the extra dimension of the second part after the partition curtain is unfolded compensates for the limited length of the second roller, allowing the partition curtain to better serve its function of blocking the view.

[0007] In this application, the first reinforcing rib provides support for the second part of the partition curtain. When the partition curtain is unfolded, the first reinforcing rib, through its rigidity, provides support for the second part, preventing the edges of the second part from sagging. When the partition curtain is rolled up on the second roller, the first reinforcing rib, through its rigidity, provides support for the second part, preventing the edges of the second part from collapsing.

[0008] In some possible implementations, along the axial direction of the second spool, the first reinforcing rib extends from one edge of the second portion to the other edge.

[0009] In this implementation, by having the first reinforcing rib cover the entire second part along the axial direction of the second roller, not only can the first reinforcing rib provide stronger support, but it can also cover the edge of the second part, thereby further improving the support effect of the first reinforcing rib on the second part. This helps to prevent the edge of the second part from sagging when the partition curtain is unfolded, and also prevents the edge of the second part from collapsing when the partition curtain is rolled up on the second roller.

[0010] In some possible implementations, the second part includes a first end and a second end opposite to each other, with the first end of the second part connected to the first part. A first reinforcing rib is located near the first end of the second part relative to the second end of the second part.

[0011] In this implementation, since the area near the connection between the first end of the second part and the first part is where the width of the second part begins to change significantly, the risk of sagging and collapse near the first end of the second part is higher. By designing the first reinforcing rib close to the first end of the second part, it is beneficial to strengthen the support near the first end of the second part, which helps to prevent the edge of the second part from sagging when the partition curtain is unfolded, and also prevents the edge of the second part from collapsing when the partition curtain is rolled up on the second roller.

[0012] In some possible implementations, when the partition curtain is rolled up on the second roller, the first reinforcing rib abuts against the first part.

[0013] In this implementation, the above design ensures that the first reinforcing rib is positioned adjacent to the first part when the partition curtain is unfolded, providing support for areas with a high risk of sagging and collapse. This better prevents the edge of the second part from sagging when the partition curtain is unfolded, and also prevents the edge of the second part from collapsing when the partition curtain is rolled up on the second roller.

[0014] In some possible implementations, there are multiple first reinforcing ribs. When the partition curtain is unfolded, multiple first reinforcing ribs are arranged at intervals along the arrangement direction of the first and second parts.

[0015] In this implementation, by designing multiple first reinforcing ribs, the supporting force provided by the first reinforcing ribs is enhanced, so that the structure of the second part of the partition curtain is more stable. This helps to better prevent the edge of the second part from sagging when the partition curtain is unfolded, and to prevent the edge of the second part from collapsing when the partition curtain is rolled up on the second roller.

[0016] In some possible implementations, multiple first stiffeners are arranged at equal intervals, and the spacing L between two adjacent first stiffeners satisfies:

[0017] L = S / N, N ≥ 2, where S is the circumference of the second scroll and N is the number of the first reinforcing ribs.

[0018] In this implementation, the equally spaced arrangement of multiple first reinforcing ribs provides stable support for the second part of the partition curtain, which is beneficial to the structural stability of the partition curtain. Through the design of the spacing between adjacent first reinforcing ribs, the number of first reinforcing ribs, and the circumference of the second roller, multiple first reinforcing ribs can be located on the same layer when the partition curtain is rolled up to the second roller. This avoids the multiple first reinforcing ribs overlapping radially on the second roller, thus preventing the partition curtain from becoming too large when rolled up to the second roller, which is beneficial for the miniaturization design of the curtain device.

[0019] In some possible implementations, multiple first reinforcing ribs are arranged at non-equidistant intervals. When the partition curtain is rolled up on the second roller, multiple first reinforcing ribs are arranged at intervals along the circumference of the second roller.

[0020] In this implementation, multiple first reinforcing ribs are arranged at equal intervals to ensure that when the partition curtain is rolled up to the second roller, the multiple first reinforcing ribs are arranged at intervals along the circumference of the second roller. This allows the first reinforcing ribs in different layers to be staggered, avoiding the first reinforcing ribs in different layers from touching each other, which would cause the size of the partition curtain to be too large after being rolled up to the second roller. This is beneficial for achieving structural stability of the partition curtain while realizing a miniaturized design.

[0021] In some possible implementations, the curtain assembly further includes a second reinforcing rib, which is mounted on the second portion and has a stiffness greater than that of the second portion. Along the axial direction of the second roller, the second reinforcing rib covers at least a portion of the second portion. When the curtain is unfolded, the second reinforcing rib is located on the side of the first reinforcing rib away from the second roller.

[0022] In this implementation, by designing a second reinforcing rib, it can work together with the first reinforcing rib to provide structural support for the partition curtain, thereby further improving the structural stability of the partition curtain, preventing the edge of the second part from sagging when the partition curtain is unfolded, and preventing the edge of the second part from collapsing when the partition curtain is rolled up on the second roller.

[0023] In some possible implementations, the second part includes a first sub-part and a second sub-part, with the first sub-part connecting the first part and the second sub-part. Along the axial direction of the second reel, the width of the second sub-part is greater than the width of the first sub-part, and a second reinforcing rib is disposed in the second sub-part.

[0024] In this implementation, when the curtain device is applied to the cabin, the cabin glass typically has a recessed space compared to other parts of the cabin. By designing the second sub-section, it can fit more closely to this recessed space, thereby further enhancing privacy. By providing a second reinforcing rib in the second sub-section, it is possible to prevent the edges of the second sub-section from sagging when the curtain is unfolded, and to prevent the edges of the second sub-section from collapsing when the curtain is rolled up on the second roller.

[0025] In some possible implementations, when the partition curtain is rolled up on the second roller, the second reinforcing rib abuts against the first sub-section.

[0026] In this implementation, since the area near the connection between the second sub-section and the first sub-section is where the width of the second sub-section begins to change significantly, the risk of sagging and collapse is higher near this connection. The above design, with the second reinforcing rib positioned adjacent to the first sub-section when the partition curtain is unfolded, provides support to the area with a high risk of sagging and collapse, thereby better preventing the edges of the second sub-section from sagging when the partition curtain is unfolded, and preventing the edges of the second sub-section from collapsing when the partition curtain is rolled up on the second roller.

[0027] In some possible implementations, the partition curtain has multiple slots, which are spaced apart and arranged at least in the second part, with a first reinforcing rib formed between two adjacent slots. When the partition curtain is unfolded, the slots have a first dimension along the axial direction of the second roller, and the slots have a second dimension along the arrangement direction of the first and second parts, with the first dimension being larger than the second dimension.

[0028] In this implementation, by designing the first dimension to be larger than the second dimension, the rigidity of the multiple first reinforcing ribs on the second roller is greater than the rigidity in the arrangement direction of the first and second parts when the partition curtain is unfolded. This makes the partition curtain easier to roll up and unfold. There is greater resistance when rolling up along the axial direction of the second roller. Thus, the first reinforcing ribs not only provide structural support for the second part, but also facilitate the smoothness of the rolling up and unfolding of the partition curtain.

[0029] In some possible implementations, at least a portion of the multiple slots are arrayed in the second portion along a first direction, wherein the first direction is the arrangement direction of the first portion and the second portion when the partition curtain is unfolded.

[0030] In this implementation, the multiple slots are arrayed as described above, which not only improves the structural stability of the second part, but also facilitates the smoothness of the second part's winding and unwinding.

[0031] In some possible implementations, the orthographic projection of the slot on the second part is strip-shaped, rectangular, racetrack-shaped, or elliptical.

[0032] In some possible implementations, some of the slots in the multiple slots are arranged at intervals along the axial direction of the second roll, so that the first reinforcing rib can present a mesh structure, which is beneficial to improving the support effect on the second part.

[0033] In some possible implementations, at least some of the slots extend through both sides of the second part along the axial direction of the second roll, which helps to reduce the resistance of the first reinforcing rib to the winding of the partition curtain, thereby improving the smoothness of the winding process of the partition curtain.

[0034] In some possible implementations, the curtain device also includes a filling portion disposed in the slot, the stiffness of which is less than the stiffness of the first reinforcing rib.

[0035] In this implementation, the filling part can fill the groove, so that the overall appearance of the partition curtain is a relatively flat surface, which is beneficial to improving its appearance.

[0036] In some possible implementations, the partition curtain is provided with multiple ventilation holes. When the partition curtain is unfolded and exposed on the side of the curtain, the partition curtain partially overlaps with the curtain, and the ventilation holes are located in the area where the partition curtain and the curtain overlap.

[0037] In this implementation, by setting multiple ventilation holes on the partition curtain, the interference of airflow on the partition curtain can be reduced, allowing airflow to pass through the ventilation holes when airflow is present, reducing disturbance to the partition curtain and improving its stability. Furthermore, since the multiple ventilation holes are located in the area where the partition curtain overlaps with the screen, the screen can block multiple ventilation holes, preventing light leakage at these points.

[0038] In some possible implementations, the curtain assembly further includes a base, a support, and a first motor. Both a first and a second roller are mounted on the base. The support is positioned opposite the base, with one end of the curtain connected to the first roller and the opposite end connected to the support. One end of the partition curtain is connected to the second roller, and the opposite end of the partition curtain is connected to the support. The first motor is mounted on the base and drives the first roller to rotate; alternatively, the first motor drives both the first and second rollers to rotate.

[0039] In this implementation, the first motor can simultaneously drive the first and second rollers to rotate, allowing the curtain and the partition curtain to be vertically unfolded and retracted simultaneously. Furthermore, the bracket simultaneously fixing one end of the curtain and one end of the partition curtain facilitates the synchronous coordination of their unfolding and retraction.

[0040] In some possible implementations, the curtain assembly also includes a torsion spring, one end of which is fixed to the base and the other end to a second roller. When the curtain is rolled up to the second roller, the torsion spring is in its initial state. When the curtain is unfolded, the torsion spring is in a stretched state.

[0041] In this implementation, the design of the torsion spring ensures that when the partition curtain is rolled up on the second roller, the torsion spring is free from external force. When the partition curtain is unfolded, the torsion spring is subjected to the force of the rotation of the second roller, thereby generating elastic tensile deformation. When the partition curtain is fully unfolded vertically, the torsion spring can drive the second roller to reverse through its deformation restoring force, thereby tightening the partition curtain and preventing the partition curtain from wrinkling or bending.

[0042] In other possible implementations, after the partition curtain is fully vertically unfolded, the second roller can be reversed by setting a motor to tighten the partition curtain, or the second roller can be reversed by a motor in conjunction with a torsion spring to tighten the partition curtain.

[0043] In some possible implementations, the curtain device further includes a second motor, a first lead screw, a first slider, a second slider, a third motor, and the second lead screw. The second motor is mounted on a base. The first lead screw extends axially along the second roller and connects the second motor and the second roller. The second motor drives the second roller to move along the first lead screw. The first slider is fixed to the end of the curtain away from the second roller, and the second slider is fixed to a bracket. The first and second sliders are movably connected. The third motor is mounted on the bracket. The second lead screw extends axially along the second roller and connects the third motor and the first slider. The third motor drives the first slider to move relative to the second slider along the second lead screw.

[0044] In this implementation, the rotational output of the second motor is converted into a linear drive via the first lead screw, thereby driving the second roller to move along its axis. The rotational output of the third motor is also converted into a linear drive via the second lead screw, allowing the end of the partition curtain furthest from the second roller to move along the axis of the second roller. The second and third motors enable the second roller and the partition curtain to move together along the axis of the second roller, thus achieving the lateral unfolding and retraction of the partition curtain. The design of the first and second sliding members effectively limits the vertical movement of the partition curtain, preventing slackness, and also guides its lateral movement.

[0045] The second and third motors can rotate at the same speed, so that the two ends of the partition curtain can move synchronously and in the same direction. This can prevent the partition curtain from being pulled due to uneven force on both ends, thus preventing wrinkles and damage to the partition curtain.

[0046] Secondly, this application provides a control method. The control method includes:

[0047] Acquire control information, which indicates the target state of the curtain device. The target state includes a retracted state, a first unfolded state, or a second unfolded state.

[0048] Based on the control information, control the curtain device to be in the target state;

[0049] The curtain assembly includes a curtain, a partition curtain, a first roller, a second roller, and a first reinforcing rib.

[0050] The curtain is connected to the first roller, and the second roller is located on the back side of the curtain. The partition curtain includes a first part and a second part. The first part is connected between the second roller and the second part. Along the axial direction of the second roller, the width of the second part is greater than the width of the first part and greater than the length of the second roller.

[0051] A first reinforcing rib is disposed in the second part, the stiffness of the first reinforcing rib is greater than the stiffness of the second part, and along the axial direction of the second roll, the first reinforcing rib covers at least a portion of the second part;

[0052] In the retracted state, the curtain is rolled up on the first roller, and the partition curtain is rolled up on the second roller;

[0053] In the first unfolded state, both the curtain and the partition curtain are unfolded along the first direction, with the partition curtain located on the back side of the curtain;

[0054] In the second unfolded state, the curtain remains in the posture of the first unfolded state, the partition curtain unfolds along the axis of the second roller, and at least part of the second section is exposed on the side of the curtain.

[0055] In this application, since the lateral dimension of the overhead space in the cabin is typically smaller than that of the bottom space, the installation space provided for the curtain device is limited, making it difficult to make the second roller long. By designing the width of the second part to be greater than the width of the first part, the extra dimension of the second part after the partition curtain is unfolded compensates for the limited length of the second roller, allowing the partition curtain to better serve its function of blocking the view.

[0056] In this application, the first reinforcing rib provides support for the second part of the partition curtain. When the partition curtain is unfolded, the first reinforcing rib, through its rigidity, provides support for the second part, preventing the edges of the second part from sagging. When the partition curtain is rolled up on the second roller, the first reinforcing rib, through its rigidity, provides support for the second part, preventing the edges of the second part from collapsing.

[0057] In some possible implementations, the current state of the curtain device is a retracted state, and the target state is a second unfolded state. Based on control information, the curtain device is controlled to be in the target state, including:

[0058] The control curtain unfolds along the first direction, and the partition curtain unfolds along the first direction;

[0059] Control the second roller to move together with the partition curtain along the axial direction of the second roller, so that at least part of the second part is exposed on the side of the curtain;

[0060] The current state of the curtain device is the second unfolded state, and the target state is the retracted state. Based on the control information, the curtain device is controlled to enter the target state, including:

[0061] Control the second roller to move together with the partition curtain along the axial direction of the second roller, with the partition curtain located on the back side of the curtain;

[0062] Control the first roller to roll up the curtain and the second roller to roll up the partition curtain.

[0063] In this implementation, the first motor can simultaneously drive the first and second rollers to rotate, thereby enabling the curtain and partition curtain to be vertically unfolded and retracted at the same time.

[0064] Some possible implementations include controlling the second roller to move together with the partition curtain along the axial direction of the second roller, including:

[0065] Control the second motor to drive the second roller to move along the axial direction of the second roller, and control the third motor to drive the end of the partition curtain away from the second roller to move along the axial direction of the second roller;

[0066] The second motor and the third motor have the same rotational speed.

[0067] In this implementation, the second and third motors can rotate at the same speed, so that the opposite ends of the partition curtain can move synchronously and in the same direction. This prevents the partition curtain from being pulled due to uneven force at both ends, thus preventing wrinkles and damage to the partition curtain.

[0068] Among some possible implementations, after controlling the curtain to unfold along the first direction and the partition curtain to unfold along the first direction, the method further includes:

[0069] Control the second roller to reverse and tighten the partition curtain.

[0070] In this implementation, the torsion spring is designed so that when the partition curtain is rolled up to the second roller, the torsion spring experiences no external force. When the partition curtain is unfolded, the torsion spring is subjected to the rotational force of the second roller, resulting in elastic tensile deformation. When the partition curtain is fully unfolded vertically, the torsion spring can drive the second roller to reverse its direction through its deformation restoring force, thereby tightening the partition curtain and preventing it from wrinkling or bending. Alternatively, the partition curtain can be tightened by using a motor to drive the second roller to reverse its direction.

[0071] Some possible implementations include controlling the curtain to unfold along a first direction and the partition curtain to unfold along a first direction, including:

[0072] Keep the partition curtain taut.

[0073] In this implementation, during the vertical unfolding of the partition curtain, the rotation of the second roller is controlled to keep the partition curtain taut at all times, thus preventing the partition curtain from wrinkling or bending.

[0074] In some possible implementations, the curtain device is applied to the cabin or vehicle, and the curtain device is located between two cabin doors;

[0075] When the hatch is opened, the method also includes:

[0076] Control the second roller to move together with the partition curtain along the axial direction of the second roller, and retract the partition curtain along the axial direction of the second roller;

[0077] When the hatch is closed, the method also includes:

[0078] Control the second roller to move together with the partition curtain along the axial direction of the second roller, and unfold the partition curtain along the axial direction of the second roller.

[0079] In this implementation, by controlling the linkage between the cabin door and the partition curtain, the partition curtain can be automatically retracted laterally when the cabin door is opened, providing more space for the user to enter the cabin. Conversely, by controlling the linkage between the cabin door and the partition curtain, the partition curtain can be automatically extended laterally after the cabin door is closed, providing the user with privacy.

[0080] The two second rollers on each side can share the same motor, allowing them to operate simultaneously. Alternatively, each second roller can be controlled independently. When the hatch is open, the second roller on the side with the open hatch moves laterally to retract the partition curtain. When the hatch is closed, the second roller on the side with the closed hatch moves laterally to unfold the partition curtain.

[0081] Thirdly, this application provides a control device. The control device includes:

[0082] At least one processor, coupled to at least one memory, is used to execute computer instructions stored in the memory to cause the control device to perform any of the methods described in the second aspect.

[0083] Fourthly, this application provides a chip or chip system. The chip or chip system includes at least one processing circuit, at least one processor circuit for running a computer program, causing the chip or chip system to perform any of the methods described in the second aspect.

[0084] Fifthly, 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 any of the methods described in the second aspect.

[0085] Sixthly, this application provides a computer program product. When the computer program product is run on a computer, it causes the computer to perform any of the methods described in the second aspect.

[0086] In a seventh aspect, this application provides a cockpit. The cockpit includes any of the curtain devices described in the first aspect.

[0087] In this application, the screen is used for projection, and the partition curtain works in conjunction with the screen to block the view and provide privacy. In the first unfolded state, the screen is vertically unfolded, blocking part of the view between the passenger cabin and the front driver's cabin, providing a degree of privacy. The screen can also be used for projection for entertainment. In the second unfolded state, the partition curtain is horizontally unfolded. Together with the screen, the partition curtain blocks the view between the passenger cabin and the front driver's cabin, further enhancing cabin privacy.

[0088] Eighthly, this application provides a means of transportation. The means of transportation includes any of the curtain devices described in the first aspect;

[0089] Or, including any of the modules in the seventh aspect.

[0090] In this application, the screen is used for projection, and the partition curtain works in conjunction with the screen to block the view and provide privacy. In the first unfolded state, the screen is vertically unfolded, blocking part of the view between the passenger cabin and the front driver's cabin, providing a degree of privacy. The screen can also be used for projection for entertainment. In the second unfolded state, the partition curtain is horizontally unfolded. Together with the screen, the partition curtain blocks the view between the passenger cabin and the front driver's cabin, further enhancing cabin privacy. Attached Figure Description

[0127] The embodiments of this application are described below with reference to the accompanying drawings.

[0128] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Multiple" refers to at least two.

[0129] The directional terms mentioned in the embodiments of this application, such as "upper", "lower", "inner", "outer", "top", "bottom", "side", etc., are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0130] In the embodiments of this application, the relative positional relationships mentioned, such as parallel, perpendicular, and aligned, are defined in relation to the current technological level, rather than being absolutely strict. Slight deviations are permissible; approximations of parallelism, perpendicularity, or alignment are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0131] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0132] The following section presents an application example of the curtain device 1 in the vehicle 1000 and the cabin 100.

[0133] Please refer to the following: Figures 1A to 1C , Figure 1A This is a schematic diagram of a vehicle 1000 provided in one embodiment of this application in some embodiments; Figure 1B yes Figure 1A A schematic diagram of the curtain device 1 in the vehicle 1000 shown in some embodiments in a first unfolded state; Figure 1C yes Figure 1A The diagram shows the curtain device 1 in the vehicle 1000 in some embodiments in a second unfolded state.

[0134] In some embodiments, the vehicle 1000 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. Figures 1A to 1C In this embodiment, the vehicle 1000 is described as an example. Of course, other types of vehicles 1000 can also adopt a similar structure, which will not be described in detail below.

[0135] It should be noted that, Figures 1A to 1C The diagram only illustrates a portion of the structure of the vehicle 1000. In other embodiments, the vehicle 1000 may include more or fewer structures, which is not limited here.

[0136] In some embodiments, the vehicle 1000 may include a cabin 100. For example, when the vehicle 1000 is a vehicle, the cabin 100 may be the front cabin 100 or the rear cabin 100. In this embodiment, the cabin 100 is illustrated as the rear cabin 100.

[0137] For example, a screen device 1 can be installed in the cockpit 100. The screen device 1 can be fixed to the top of the cockpit 100. The screen device 1 can be used for projection for audio-visual entertainment, and can also be used to isolate the cockpit 100 for privacy protection.

[0138] The screen device 1 may include a screen 11 and a partition curtain 12. The screen 11 is used for projection, and the partition curtain 12 is used in conjunction with the screen 11 to block the line of sight for privacy protection.

[0139] The curtain device 1 may include a retracted state, a first unfolded state, and a second unfolded state.

[0140] Please see Figure 1A The curtain device 1 is in the retracted state. The curtain device 1 is located on the top of the cockpit 100 and blocks the line of sight between the cockpit 100 and the front cockpit.

[0141] Please see Figure 1B The screen device 1 is in the first unfolded state, and the screen 11 is unfolded vertically. The screen 11 blocks part of the line of sight between the cockpit 100 and the front cockpit, which can provide a certain degree of privacy protection. The screen 11 can also be used for projection for entertainment.

[0142] Please see Figure 1C When the curtain device 1 is in the second unfolded state, the partition curtain 12 is unfolded horizontally. The partition curtain 12 and the curtain 11 together cover the space between the cabin 100 and the front cockpit, which can further enhance the privacy of the cabin 100.

[0143] Please see Figures 2A to 2C , Figure 2A This is a schematic diagram of the cockpit 100 provided in one embodiment of this application in some embodiments; Figure 2B yes Figure 2A A schematic diagram of the curtain device 1 in the cockpit 100 in its first unfolded state; Figure 2C yes Figure 2A A schematic diagram of the curtain device 1 in the second unfolded state in the cockpit 100 shown.

[0144] Please see Figure 2A The curtain device 1 is in the retracted state. Since the curtain device 1 is located on the top of the cockpit 100, it provides a good view in front of the cockpit 100.

[0145] Please see Figure 2B The screen device 1 is in the first unfolded state, the screen 11 is unfolded vertically, the screen 11 blocks part of the front view of the cabin 100 so that the cabin 100 has a certain degree of privacy, and the screen 11 can be used for projection for entertainment.

[0146] Please see Figure 2C The curtain device 1 is in the second unfolded state, and the partition curtain 12 is unfolded horizontally. The partition curtain 12 and the curtain 11 together block the forward view of the cabin 100, making it difficult to see inside the cabin 100 from the front, thus further enhancing the privacy of the cabin 100.

[0147] The partition curtain 12 is designed to mimic the interior shape of the cabin 100, so that when the curtain device 1 is in the second unfolded state, the partition curtain 12 can fit well with the inner wall of the cabin 100, further improving the effect of the partition device in shielding the cabin 100 and enhancing the privacy of the cabin 100.

[0148] Next, we will introduce the basic structure of the curtain device 1.

[0149] Please see Figures 3 to 4C , Figure 3 This is a schematic diagram of the structure of the curtain device 1 provided in one embodiment of the present application in some embodiments; Figure 4A yes Figure 3 A schematic diagram of the curtain device 1 in the retracted state. Figure 4B yes Figure 3 A schematic diagram of the curtain device 1 in its first unfolded state; Figure 4C yes Figure 3 The diagram shows the curtain device 1 in its second unfolded state.

[0150] Please see Figure 3 In some implementations, the curtain device 1 may further include a first roller 13 and a second roller 14. The curtain 11 is connected to the first roller 13, which is used to roll up or unroll the curtain 11. The second roller 14 is located on the back side of the curtain 11, and the partition curtain 12 is connected to the second roller 14, which is used to roll up or unroll the partition curtain 12.

[0151] It should be noted that, for ease of observation, Figure 3 Part of the structure of the curtain device 1 is hidden inside.

[0152] For example, the second roller 14 can also move axially relative to the first roller 13 along the second roller 14 to achieve the lateral unfolding and lateral retraction of the partition curtain 12.

[0153] In some examples, the two second rollers 14 can move simultaneously in opposite directions along their axial directions to allow the two partition curtains 12 to unfold laterally at the same time. Conversely, the two second rollers 14 can move simultaneously towards each other along their axial directions to allow the two partition curtains 12 to retract laterally at the same time. This design reduces the number of drive structures, simplifies the structure, and facilitates the miniaturization of the curtain device 1.

[0154] In other examples, both second rollers 14 can move independently along their axial direction to allow for the independent lateral unfolding or retraction of a single partition curtain 12. This design facilitates a wider range of applications for the curtain device 1.

[0155] In some other examples, the two second scrolls 14 can move simultaneously along the axial direction of the second scroll 14, or they can each move independently along the axial direction of the second scroll 14, further enriching the application scenarios of the curtain device 1.

[0156] Please see Figure 3 and Figure 4A In some embodiments, the curtain device 1 may further include a base 15, on which the first roller 13 and the second roller 14 may both be mounted. When the curtain device 1 is in the retracted state, the curtain 11 is rolled up on the first roller 13, and the partition curtain 12 is rolled up on the second roller 14. The curtain 11, partition curtain 12, first roller 13, and second roller 14 are all housed within the base 15. The base 15 provides a fixed base point for the first roller 13 and the second roller 14, and also provides housing space for the curtain 11, partition curtain 12, first roller 13, and second roller 14, thereby protecting the curtain 11, partition curtain 12, first roller 13, and second roller 14 and providing dust and impact protection.

[0157] Please see Figure 3 and Figure 4B In some embodiments, the curtain device 1 is in a first unfolded state, and the partition curtain 12 may be located on the back side of the curtain 11. In other words, the partition curtain 12 cannot be seen from the front of the curtain 11.

[0158] In some other embodiments, the curtain device 1 is in a first unfolded state, and the partition curtain 12 may be partially located on the back side of the curtain 11 and partially exposed on the side of the curtain 11.

[0159] Please see Figure 3 and Figure 4C In some embodiments, the curtain device 1 is in a second unfolded state, and the partition curtain 12 can be at least partially exposed on the side of the curtain 11 to cooperate with the curtain 11 to achieve the function of blocking the view.

[0160] Please see Figures 5A to 5C , Figure 5A yes Figure 3A schematic diagram of the structure of the first roller 13 and the second roller 14 in some embodiments of the curtain device 1 shown; Figure 5B yes Figure 3 A schematic diagram of the structure of the first roller 13 and the second roller 14 in some other embodiments of the curtain device 1 shown; Figure 5C yes Figure 3 A schematic diagram of the structure of the first roller 13 and the second roller 14 in some other embodiments of the curtain device 1 shown.

[0161] It should be noted that, Figures 5A to 5C The dotted lines in the diagram represent the axis, and the dashed lines with arrows indicate the direction in which the second scroll 14 can move relative to the first scroll 13.

[0162] Please see Figure 3 and Figure 5A In some embodiments, the first spool 13 and the second spool 14 can both be cylindrical structures, and the axis of the first spool 13 can be parallel to the axis of the second spool 14. This design facilitates the installation of the first spool 13 and the second spool 14, simplifying the structure.

[0163] For example, the axes of the two first rollers 13 can coincide, which is beneficial for the two partition curtains 12 to move in the same plane.

[0164] Please see Figure 3 and Figure 5B In other embodiments, both the first reel 13 and the second reel 14 can be cylindrical structures, and the axial direction of the first reel 13 can intersect with the axis of the second reel 14. This design allows for changes in the space occupied by the second reel 14 and the space occupied by the lateral movement of the second reel 14 to adapt to the interior space of the cabin 100 or the vehicle 1000.

[0165] For example, the top of the cabin 100 or vehicle 1000 can provide an installation space that is trapezoidal with a narrow top and a wide bottom. By placing the second reel 14 at an angle, the utilization rate of the top space of the cabin 100 or vehicle 1000 can be improved.

[0166] Please see Figure 3 and Figure 5C In some embodiments, the first reel 13 may have a U-shaped structure. The first reel 13 may include two straight cylindrical structures and an arc-shaped structure connecting the two straight cylindrical structures. Two second reels 14 may be respectively arranged corresponding to the two straight cylindrical structures of the first reel 13, and the axis of the second reel 14 is parallel to the axis of the straight cylindrical structure of the first reel 13. This design can change the space occupied by the first reel 13 and the second reel 14, as well as the space occupied by the lateral movement of the second reel 14, to adapt to the interior space of the cockpit 100 or the vehicle 1000.

[0167] For example, the top of the cabin 100 or vehicle 1000 can provide an arc-shaped installation space. Through the U-shaped design of the first reel 13, it can fit more closely to the top of the cabin 100 or vehicle 1000, thereby improving the utilization rate of the top space of the cabin 100 or vehicle 1000.

[0168] It should be noted that, Figures 5A to 5C The diagram only shows a portion of the design of the first scroll 13 and the second scroll 14. The shape and relative position of the first scroll 13 and the second scroll 14 can be adapted to the internal structure of the cabin 100 or the vehicle 1000.

[0169] Next, we will discuss the technical issues associated with making the blinds wider.

[0170] Please see Figures 6A to 6C , Figure 6A This is a schematic diagram of the structure of the second roller 14 unfolding the partition curtain 12 in some embodiments; Figure 6B yes Figure 6A The diagram shown is a structural schematic of the second roller 14 winding up the partition curtain 12 in some embodiments. Figure 6C yes Figure 6B The diagram shown is a partial cross-sectional view of the structure in some embodiments.

[0171] Please see Figure 2C and Figure 6A In some embodiments, the partition curtain 12 may include a first portion 121 and a second portion 122, with the first portion 121 connected between the second roller 14 and the second portion 122. Along the axial direction of the second roller 14, the width of the second portion 122 may be greater than the width of the first portion 121 and greater than the length of the second roller 14.

[0172] In this embodiment, since the lateral dimension of the top space in the cabin 100 is usually smaller than that of the bottom space, the installation space provided for the curtain device 1 is limited, making it difficult to make the second roller 14 long. By designing the width of the second part 122 to be greater than the width of the first part 121, the extra dimension of the second part 122 after the partition curtain 12 is unfolded can compensate for the limited length of the second roller 14, so that the partition curtain 12 can better serve its function of blocking the line of sight.

[0173] However, since the side edges of the second part 122 have no structural support, the side edge area of ​​the second part 122 will sag, thereby affecting the blocking effect of the partition curtain 12 and the appearance of the partition curtain 12 when it is unfolded.

[0174] It should be noted that, Figure 6AThe dashed line in the middle is a schematic diagram of the boundary division between the first part 121 and the second part 122. It can be understood that in some other embodiments, the boundary between the first part 121 and the second part 122 may be located elsewhere. Figure 6A The dotted line with the arrow in the middle indicates the downward droop of the side edge of the second part 122.

[0175] Please see Figure 6B and Figure 6C When the second roller 14 rolls up the partition curtain 12, because the width of the second part 122 is greater than the length of the second roller 14, the edges of the second part 122 may collapse. This causes the second part 122 to come into contact with the end face and other structures of the second roller 14, resulting in the second part 122 becoming contaminated with lubricant, dust, machine oil, etc. from the end face of the second roller 14. Furthermore, the long-term collapse of the edges of the second part 122 also poses a risk of wrinkling, which is detrimental to the appearance of the partition curtain 12.

[0176] It should be noted that, Figure 6B and Figure 6C The dotted line with the arrow in the middle is a schematic diagram of the edge collapse of the second part 122. Figure 6C The number of layers and the spacing between layers of the middle partition curtain 12 are limited during winding, in order to facilitate observation. Figure 6C The structure was made thicker and the gaps were increased, but this did not cause structural limitations.

[0177] Therefore, by Figures 6A to 6C It can be seen that by increasing the width of the second part 122 of the partition curtain 12, the effect of blocking the view when the partition curtain 12 is unfolded can be improved. However, since the edge of the second part 122 has no structural support, the edge of the second part 122 sags when the partition curtain 12 is unfolded, and the edge of the second part 122 collapses when the partition curtain 12 is rolled up.

[0178] The technical solutions to the above-mentioned technical problems will be introduced next.

[0179] Please see Figures 7A to 7C , Figure 7A yes Figure 3 The diagram shows the structure of the second roller 14 unfolding the partition curtain 12 in some embodiments of the curtain device 1 shown; Figure 7B yes Figure 7A The diagram shown is a schematic representation of the structure during winding in some embodiments. Figure 7C yes Figure 7B The diagram shows a structure that conceals the partition curtain 12.

[0180] Please see Figure 7A and Figure 7BIn some embodiments, the curtain device 1 may further include a first reinforcing rib 16. The first reinforcing rib 16 may be disposed on the second portion 122, the stiffness of the first reinforcing rib 16 being greater than the stiffness of the second portion 122, and the first reinforcing rib 16 covering at least a portion of the second portion 122 along the axial direction of the second roll 14.

[0181] In this embodiment, the first reinforcing rib 16 provides support for the second portion 122 of the partition curtain 12. When the partition curtain 12 is unfolded, the first reinforcing rib 16 provides support for the second portion 122 through its rigidity, preventing the edges of the second portion 122 from sagging. When the partition curtain 12 is rolled up to the second roller 14, the first reinforcing rib 16 provides support for the second portion 122 through its rigidity, preventing the edges of the second portion 122 from collapsing.

[0182] It should be noted that, Figure 7B The thickness of each layer of the partition curtain 12, the thickness of the first reinforcing rib 16, and the gap between adjacent layers are all shown in enlarged diagrams. Their absolute and relative dimensions are for illustrative purposes only and do not constitute a limitation.

[0183] For example, along the axial direction of the second spool 14, the first reinforcing rib 16 may extend from one edge of the second portion 122 to the other edge.

[0184] In this embodiment, by having the first reinforcing rib 16 cover the entire second part 122 along the axial direction of the second roller 14, the first reinforcing rib 16 can not only provide stronger support, but also cover the edge of the second part 122, thereby further improving the support effect of the first reinforcing rib 16 on the second part 122. This helps to prevent the edge of the second part 122 from sagging when the partition curtain 12 is unfolded, and also prevents the edge of the second part 122 from collapsing when the partition curtain 12 is rolled up to the second roller 14.

[0185] The second part 122 may include a first end 1221 and a second end 1222 opposite to each other, with the first end 1221 of the second part 122 connected to the first part 121. The first reinforcing rib 16 is close to the first end 1221 of the second part 122 relative to the second end 1222 of the second part 122.

[0186] In this embodiment, since the area near the connection between the first end 1221 and the first part 122 is where the width of the second part 122 begins to change significantly, the risk of sagging and collapse near the first end 1221 of the second part 122 is higher. By designing the first reinforcing rib 16 close to the first end 1221 of the second part 122, it is beneficial to strengthen the support near the first end 1221 of the second part 122, which helps to prevent the edge of the second part 122 from sagging when the partition curtain 12 is unfolded, and to prevent the edge of the second part 122 from collapsing when the partition curtain 12 is rolled up to the second roller 14.

[0187] Please see Figure 7B When the partition curtain 12 is rolled up to the second roller 14, the first reinforcing rib 16 can abut against the first part 121.

[0188] In this embodiment, the above design ensures that the first reinforcing rib 16 is positioned adjacent to the first part 121 when the partition curtain 12 is unfolded, providing support for areas with a high risk of sagging and collapse, thereby better preventing the edge of the second part 122 from sagging when the partition curtain 12 is unfolded, and preventing the edge of the second part 122 from collapsing when the partition curtain 12 is rolled up to the second roller 14.

[0189] Please see Figure 7A and Figure 7B In some embodiments, there may be multiple first reinforcing ribs 16. When the partition curtain 12 is unfolded, multiple first reinforcing ribs 16 are arranged at intervals along the arrangement direction of the first part 121 and the second part 122.

[0190] In this embodiment, by designing multiple first reinforcing ribs 16, it is beneficial to enhance the supporting force provided by the first reinforcing ribs 16, so that the structure of the second part 122 of the partition curtain 12 is more stable, thereby better preventing the edge of the second part 122 from sagging when the partition curtain 12 is unfolded, and preventing the edge of the second part 122 from collapsing when the partition curtain 12 is rolled up to the second roller 14.

[0191] Please see Figures 7A to 7C In some examples, multiple first reinforcing ribs 16 can be arranged at equal intervals, and the distance L between two adjacent first reinforcing ribs 16 satisfies: L=S / N, N≥2, where S is the circumference of the second scroll 14 and N is the number of first reinforcing ribs 16.

[0192] In this embodiment, the multiple first reinforcing ribs 16 arranged at equal intervals provide stable support for the second part 122 of the partition curtain 12, which is beneficial to the structural stability of the partition curtain 12. Through the related design of the spacing between two adjacent first reinforcing ribs 16, the number of first reinforcing ribs 16, and the circumference of the second roller 14, the multiple first reinforcing ribs 16 can be located in the same layer when the partition curtain 12 is rolled up to the second roller 14. This avoids the multiple first reinforcing ribs 16 from overlapping radially on the second roller 14, thereby preventing the partition curtain 12 from being too large when rolled up to the second roller 14, which is beneficial to the miniaturization design of the curtain device 1.

[0193] Please see Figure 8A and Figure 8B , Figure 8A yes Figure 3 A schematic diagram of the structure of the second roller 14 unfolding the partition curtain 12 in some other embodiments of the curtain device 1 shown; Figure 8B yes Figure 8A The diagram shown is a schematic representation of the structure during winding in some embodiments.

[0194] In other examples, the multiple first reinforcing ribs 16 may be arranged at non-equidistant intervals. When the partition curtain 12 is rolled up to the second roller 14, the multiple first reinforcing ribs 16 are arranged at intervals along the circumference of the second roller 14.

[0195] In this embodiment, by designing multiple first reinforcing ribs 16 arranged at unequal intervals, when the partition curtain 12 is rolled up to the second roller 14, the multiple first reinforcing ribs 16 are arranged at intervals along the circumference of the second roller 14, so that the first reinforcing ribs 16 in different layers can be staggered, avoiding the first reinforcing ribs 16 in different layers from abutting each other, which would cause the size of the partition curtain 12 after being rolled up to the second roller 14 to be too large. This is beneficial to achieve both structural stability of the partition curtain 12 and miniaturization design.

[0196] It should be noted that, Figure 8B The thickness of each layer of the partition curtain 12, the thickness of the first reinforcing rib 16, and the gap between adjacent layers are all shown in enlarged diagrams. Their absolute and relative dimensions are for illustrative purposes only and do not constitute a limitation.

[0197] Please refer to the following: Figure 9A and Figure 9B , Figure 9A yes Figure 3 A schematic diagram of the structure of the second roller 14 unfolding the partition curtain 12 in some other embodiments of the curtain device 1 shown; Figure 9B yes Figure 9A The diagram shown is a schematic representation of the structure during winding in some embodiments.

[0198] Please see Figure 9AIn some embodiments, the curtain device 1 may further include a second reinforcing rib 17, which is mounted on the second portion 122. The stiffness of the second reinforcing rib 17 is greater than that of the second portion 122, and along the axial direction of the second roller 14, the second reinforcing rib 17 covers at least a portion of the second portion 122. When the partition curtain 12 is unfolded, the second reinforcing rib 17 is located on the side of the first reinforcing rib 16 away from the second roller 14.

[0199] In this embodiment, by designing the second reinforcing rib 17, it can work together with the first reinforcing rib 16 to provide structural support for the partition curtain 12, thereby further improving the structural stability of the partition curtain 12, preventing the edge of the second part 122 from sagging when the partition curtain 12 is unfolded, and preventing the edge of the second part 122 from collapsing when the partition curtain 12 is rolled up to the second roller 14.

[0200] For example, along the axial direction of the second spool 14, the second reinforcing rib 17 may extend from one side edge of the second portion 122 to the opposite side edge to further enhance the supporting effect of the second reinforcing rib 17 on the second portion 122.

[0201] The number of second reinforcing ribs 17 can be one or more. In the accompanying drawings of this application, one second reinforcing rib is used for illustration. It can be understood that in some other embodiments, the number of second reinforcing ribs 17 can be more.

[0202] Please see Figure 2C and Figure 9A For example, the second portion 122 may include a first sub-portion 122a and a second sub-portion 122b, with the first sub-portion 122a connected between the first portion 121 and the second sub-portion 122b. Along the axial direction of the second reel 14, the width of the second sub-portion 122b is greater than the width of the first sub-portion 122a, and a second reinforcing rib 17 is disposed on the second sub-portion 122b.

[0203] In this embodiment, when the curtain device 1 is applied to the cabin 100, the glass window 2 of the cabin 100 typically has a recessed space compared to other parts of the cabin. By designing the second sub-part 122b, it can fit more closely to this recessed space, thereby further enhancing privacy. By providing a second reinforcing rib 17 in the second sub-part 122b, it is possible to prevent the edge of the second sub-part 122b from drooping when the partition curtain 12 is unfolded, and to prevent the edge of the second sub-part 122b from collapsing when the partition curtain 12 is rolled up to the second roller 14.

[0204] It should be noted that, Figure 9A The boundaries of the first sub-part 122a and the second sub-part 122b are indicated by dashed lines. It is understood that in some other embodiments, the boundaries of the first sub-part 122a and the second sub-part 122b may be located elsewhere.

[0205] Please see Figure 9A and Figure 9B When the partition curtain 12 is rolled up to the second roller 14, the second reinforcing rib 17 abuts against the first sub-section 122a.

[0206] In this embodiment, since the area near the connection between the second sub-part 122b and the first sub-part 122a is where the width of the second sub-part 122b begins to change significantly, the risk of sagging and collapse is higher near the connection between the second sub-part 122b and the first sub-part 122a. Through the above design, the second reinforcing rib 17 is positioned adjacent to the first sub-part 122a when the partition curtain 12 is unfolded, providing support for the area with a high risk of sagging and collapse. This better prevents the edge of the second sub-part 122b from sagging when the partition curtain 12 is unfolded, and also prevents the edge of the second sub-part 122b from collapsing when the partition curtain 12 is rolled up to the second roller 14.

[0207] It should be noted that, Figure 9B The thickness of each layer of the partition curtain 12, the thickness of the first reinforcing rib 16, the thickness of the second reinforcing rib 17, and the gap between adjacent layers are all shown in enlarged diagrams. Their absolute and relative dimensions are for illustrative purposes only and do not constitute a limitation.

[0208] Please see Figure 10A and Figure 10B , Figure 10A yes Figure 3 A schematic diagram of the structure of the second roller 14 unfolding the partition curtain 12 in some other embodiments of the curtain device 1 shown; Figure 10B yes Figure 10A Rear view of the structure shown.

[0209] In some embodiments, the partition curtain 12 may have multiple slots 123, which are spaced apart on at least a portion of the second portion 122, with a first reinforcing rib 16 formed between adjacent slots 123. When the partition curtain 12 is unfolded, the slots 123 have a first dimension along the axial direction of the second roller 14, and the slots 123 have a second dimension along the arrangement direction of the first portion 121 and the second portion 122, wherein the first dimension is larger than the second dimension.

[0210] In this embodiment, by designing the first dimension to be larger than the second dimension, when the partition curtain 12 is unfolded, the rigidity of the multiple first reinforcing ribs 16 on the second roller 14 is greater than the rigidity in the arrangement direction of the first part 121 and the second part 122. This makes the partition curtain 12 easier to roll up and unfold. There is greater resistance when rolling up along the axial direction of the second roller 14. Thus, the first reinforcing ribs 16 provide structural support for the second part 122 while also facilitating the smoothness of the rolling up and unfolding of the partition curtain 12.

[0211] For example, the orthographic projection of the slot 123 onto the second part 122 is strip-shaped, rectangular, racetrack-shaped, or elliptical.

[0212] The curtain device 1 may also include a filling part (not shown in the figure), which is disposed in the slot 123 and has a stiffness less than that of the first reinforcing rib 16.

[0213] In this embodiment, by providing a filling part, the slot 123 can be filled, so that the overall appearance of the partition curtain 12 is a relatively flat surface, which is beneficial to improving its appearance.

[0214] Please see Figure 10B In some examples, the second part 122 and the first reinforcing rib 16 can be an integral structure. In other words, the first reinforcing rib 16 can be integrally formed with the second part 122. The first reinforcing rib 16 is a protruding structure, and the protruding structure surrounds and forms a plurality of slots 123.

[0215] For example, the second part 122 and the first reinforcing rib 16 can be formed by weaving, 3D printing, or other methods.

[0216] The second part 122 and the first reinforcing rib 16 can be made of the same or different materials.

[0217] Please see Figure 10B and Figure 11 , Figure 11 yes Figure 10A A partial structural decomposition diagram of the structure shown.

[0218] In other examples, the second part 122 and the first reinforcing rib 16 can be separate structures; in other words, the second part 122 and the first reinforcing rib 16 can be manufactured independently and then fixed together.

[0219] The first reinforcing rib 16 surrounds and forms multiple openings 161, and the second part 122 covers one side of the first reinforcing rib 16 and forms multiple slots 123, with each slot corresponding to one of the openings 161.

[0220] Please see Figure 10B In some embodiments, at least a portion of the plurality of slots 123 may be arrayed in the second portion 122 along a first direction, wherein the first direction is the arrangement direction of the first portion 121 and the second portion 122 when the partition curtain 12 is unfolded.

[0221] In this embodiment, the array design of multiple slots 123 in the manner described above is beneficial to improving the structural stability of the second part 122, and also to the smoothness of the winding and unfolding of the second part 122.

[0222] Please see Figure 10BIn some examples, some of the slots 123 can be arranged at intervals along the axial direction of the second roll 14 so that the first reinforcing rib 16 can present a mesh structure, which is beneficial to improving the support effect on the second part 122.

[0223] Please see Figure 12 , Figure 12 yes Figure 3 The diagram shows a schematic representation of the second roller 14 unfolding the partition curtain 12 in some other embodiments of the curtain device 1 shown. It should be noted that... Figure 12 The structure shown may include Figure 10B At least some of the features in the structure shown are described, and the same features will not be repeated here.

[0224] In other examples, at least some of the slots 123 may extend through both sides of the second portion 122 along the axial direction of the second roll 14, which helps to reduce the resistance of the first reinforcing rib 16 to the winding of the partition curtain 12, thereby improving the smoothness of the winding of the partition curtain 12.

[0225] It should be noted that, Figures 10A to 12 The first reinforcing rib 16 shown in the embodiment can also be provided in the first part 121 so that the first part 121 and the second part 122 are prepared in the same way, simplifying the overall structural design.

[0226] Please see Figure 13A and Figure 13B , Figure 13A yes Figure 4C A schematic diagram of the ventilation hole 124 in the curtain device 1 shown in some embodiments; Figure 13B yes Figure 13A The diagram shows the structure of the partition curtain 12 in some embodiments of the curtain device 1 shown.

[0227] In some embodiments, the partition curtain 12 may be provided with multiple ventilation holes 124. When the partition curtain 12 is unfolded and exposed on the side of the curtain 11, the partition curtain 12 and the curtain 11 partially overlap, and the ventilation holes 124 are located in the area where the partition curtain 12 and the curtain 11 overlap.

[0228] In this embodiment, by providing multiple ventilation holes 124 on the partition curtain 12, the interference of airflow on the partition curtain 12 can be reduced, so that when airflow is present, airflow can pass through the ventilation holes 124, reducing disturbance to the partition curtain 12 and improving the stability of the partition curtain 12. In addition, since the multiple ventilation holes 124 are located in the area where the partition curtain 12 overlaps with the curtain 11, the curtain 11 can block the multiple ventilation holes 124, thus preventing light leakage at the multiple ventilation holes 124.

[0229] It should be noted that, Figure 13AThe ventilation hole 124 located on the back of the curtain 11 is indicated by a dashed line.

[0230] The following describes the drive design for the first roller 13 and the second roller 14 in the curtain device 1.

[0231] Please see Figure 14 and Figure 15 , Figure 14 yes Figure 4C The diagram shows a partial structural exploded view of the curtain device 1 in some embodiments. Figure 15 yes Figure 14 The diagram shows the structure of the curtain device 1 from another perspective.

[0232] In some embodiments, the curtain device 1 may further include a bracket 18 and a first motor 19. A first roller 13 and a second roller 14 are both mounted on a base 15. The bracket 18 is positioned opposite to the base 15. One end of the curtain 11 is connected to the first roller 13, and the opposite end of the curtain 11 is connected to the bracket 18. One end of the partition curtain 12 is connected to the second roller 14, and the opposite end of the partition curtain 12 is connected to the bracket 18. The first motor 19 is mounted on the base 15 and is driven by both the first roller 13 and the second roller 14 to drive the first roller 13 and the second roller 14 to rotate.

[0233] In this embodiment, the first motor 19 can simultaneously drive the first roller 13 and the second roller 14 to rotate, thereby enabling the curtain 11 and the partition curtain 12 to be vertically unfolded and retracted simultaneously. The bracket 18 simultaneously fixes one end of the curtain 11 and one end of the partition curtain 12, which facilitates the synchronous coordination of the unfolding and retraction of the curtain 11 and the partition curtain 12.

[0234] It should be noted that, Figure 14 and Figure 15 Only the base 15 was exploded and disassembled to allow for a better observation of the internal structure of the curtain device 1.

[0235] For example, the output shaft of the first motor 19 is provided with a first gear 20, the first spool 13 is connected to a second gear 21, and the second spool 14 is connected to a third gear 22. One side of the first gear 20 meshes with the second gear 21, and the other side of the first gear 20 meshes with the third gear 22, thereby realizing that the first gear 20 meshes with both the second gear 21 and the third gear 22 at the same time, and thus enabling the first motor 19 to drive the first spool 13 and the second spool 14 to rotate in the same direction at the same time.

[0236] It should be noted that, Figure 14 and Figure 15 The second gear 21 is indicated by a dashed circle.

[0237] In some other embodiments, the first motor 19 may drive only the first roller 13 to rotate, and the curtain device 1 may also be provided with other motors to drive the second roller 14 to rotate independently, so that the rotation drive of the first roller 13 and the rotation drive of the second roller 14 are both independent. It is understood that even if the rotation drive of the first roller 13 and the rotation drive of the second roller 14 are both independent, the rotation of the first roller 13 and the second roller 14 can be controlled to rotate in the same direction and at the same speed.

[0238] Please see Figure 15 In some embodiments, the curtain device 1 may further include a torsion spring 23, one end of which is fixed to the base 15, and the other end of which is fixed to the second roller 14. When the partition curtain 12 is rolled up to the second roller 14, the torsion spring 23 is in its original state. When the partition curtain 12 is unfolded, the torsion spring 23 is in a stretched state.

[0239] In this embodiment, the design of the torsion spring 23 ensures that when the partition curtain 12 is rolled up to the second roller 14, the torsion spring 23 is free from external force. When the partition curtain 12 is unfolded, the torsion spring 23 is subjected to the force of the rotation of the second roller 14, thereby generating elastic tensile deformation. When the partition curtain 12 is fully unfolded vertically, the torsion spring 23 can drive the second roller 14 to reverse through its deformation restoring force, thereby tightening the partition curtain 12 and preventing the partition curtain 12 from wrinkling or bending.

[0240] It should be noted that, Figure 15 The torsion spring 23 is indicated by a dashed line.

[0241] For example, one end of the torsion spring 23 can be directly fixed to the base 15, or indirectly fixed to the base 15 through other structures.

[0242] In some other embodiments, after the partition curtain 12 is fully vertically unfolded, the partition curtain 12 can be tightened by reversing the second roller 14 driven by a motor, or by reversing the second roller 14 driven by a motor in conjunction with a torsion spring 23.

[0243] In some other embodiments, the second roller 14 can be controlled to keep the partition curtain 12 taut at all times during the vertical unfolding process, so as to prevent the partition curtain 12 from wrinkling or bending.

[0244] Please see Figure 16 and Figure 17 , Figure 16 yes Figure 15 Enlarged schematic diagram of each motor in the curtain device 1 shown; Figure 17 yes Figure 15 An enlarged schematic diagram of the connection point of the support rod 30 in the curtain device 1 shown.

[0245] In some embodiments, the curtain device 1 may further include a second motor 24, a first lead screw 25, a first slider 26, a second slider 27, a third motor 28, and a second lead screw 29. The second motor 24 is mounted on the base 15. The first lead screw 25 extends axially along the second roller 14 and connects the second motor 24 and the second roller 14. The second motor 24 drives the second roller 14 to move along the first lead screw 25. The first slider 26 is fixed to the end of the partition curtain 12 away from the second roller 14. The second slider 27 is fixed to the bracket 18, and the first slider 26 and the second slider 27 are movably connected. The third motor 28 is mounted on the bracket 18. The second lead screw 29 extends axially along the second roller 14 and connects the third motor 28 and the first slider 26. The third motor 28 drives the first slider 26 to move relative to the second slider 27 along the second lead screw 29.

[0246] In this embodiment, the rotational output of the second motor 24 is converted into a linear drive by the first lead screw 25 to drive the second roller 14 to move along its axis. Similarly, the rotational output of the third motor 28 is converted into a linear drive by the second lead screw 29 to allow the end of the partition curtain 12 away from the second roller 14 to move along the axis of the second roller 14. The second motor 24 and the third motor 28 enable the second roller 14 and the partition curtain 12 to move together along the axis of the second roller 14, thus achieving the lateral unfolding and retraction of the partition curtain 12. The design of the first sliding member 26 and the second sliding member 27 allows for vertically limiting the partition curtain 12, preventing slackness, and also guides its lateral movement.

[0247] For example, the second motor 24 and the third motor 28 can rotate at the same speed so that the opposite ends of the partition curtain 12 can move synchronously and in the same direction, which can prevent the partition curtain 12 from being pulled due to uneven force at both ends, and prevent the partition curtain 12 from wrinkling, being damaged, etc.

[0248] For example, the movable connection between the first slider 26 and the second slider 27 can be a slide rail connection, a slider groove connection, etc.

[0249] In some embodiments, the curtain device 1 may further include a support link 30. The support link 30 may include a first link 301 and a second link 302, which may be hinged together. The end of the first link 301 away from the second link 302 may be hinged to the base 15, and the end of the second link 302 away from the first link 301 may be hinged to the bracket 18.

[0250] In this embodiment, by setting the support rod 30, a support can be formed between the base 15 and the bracket 18 to maintain the overall stability of the curtain 11 and the partition curtain 12, so that the curtain 11 and the partition curtain 12 can maintain structural stability during vertical unfolding and retraction, as well as after unfolding, which is beneficial to improving the user experience.

[0251] For example, with Figure 17 The diagram illustrates the following: As the curtain 11 unfolds vertically, the support 18 gradually moves away from the base 15. The end of the first rod 301 furthest from the second rod 302 rotates clockwise relative to the base 15, while the end of the second rod 302 furthest from the first rod 301 rotates counterclockwise. The angle between the first rod 301 and the second rod 302 gradually increases. As the curtain 11 retracts vertically, the support 18 gradually moves closer to the base 15. The end of the first rod 301 furthest from the second rod 302 rotates counterclockwise relative to the base 15, while the end of the second rod 302 furthest from the first rod 301 rotates clockwise. The angle between the first rod 301 and the second rod 302 gradually decreases.

[0252] For example, there can be two support rods 30, which can be located at opposite ends of the base 15, which helps to further enhance the overall stability of the curtain device 1.

[0253] The control method of curtain device 1 will be introduced next.

[0254] In some embodiments, the control method may include:

[0255] Acquire control information, the control information indicates the target state of the curtain device 1, the target state includes a retracted state, or a first unfolded state, or a second unfolded state;

[0256] Based on the control information, the control curtain device 1 is placed in the target state.

[0257] Please see Figure 4A In the retracted state, the curtain 11 is rolled up on the first roller 13, and the partition curtain 12 is rolled up on the second roller 14.

[0258] Please see Figure 4B In the first unfolded state, both the curtain 11 and the partition curtain 12 are unfolded along the first direction, with the partition curtain 12 located on the back side of the curtain 11.

[0259] Please see Figure 4C In the second unfolded state, the curtain 11 remains in the posture of the first unfolded state, the partition curtain 12 unfolds along the axis of the second roller 14, and at least part of the second part 122 is exposed on the side of the curtain 11.

[0260] Specifically, taking the current state as the retracted state, the control method of the curtain device 1 is described in detail.

[0261] Please see Figure 18 , Figure 18 This is a flowchart illustrating a control method provided in an embodiment of this application.

[0262] For example, the control method may include:

[0263] Step S10: Control the curtain 11 to unfold along the first direction and the partition curtain 12 to unfold along the first direction.

[0264] You can refer to this article. Figure 4A , Figure 4B , Figure 14 and Figure 15 During this process, the first motor 19 can drive the first roller 13 and the second roller 14 to rotate in the same direction, so as to realize the simultaneous unfolding of the curtain 11 and the partition curtain 12 along the first direction, thereby making the curtain device 1 in the first unfolded state.

[0265] Step S20: Control the second roller 14 to reverse and tighten the partition curtain 12.

[0266] Please refer to Figure 15 In some examples, after the partition curtain 12 is fully extended in the first direction, the second roller 14 is rotated in the opposite direction by a torsion spring 23 and / or a motor to tighten the partition curtain 12.

[0267] In other examples, as the partition curtain 12 unfolds along the first direction, the partition curtain 12 can be controlled to remain taut at all times, in which case step S20 is unnecessary.

[0268] In step S30, the second roller 14 and the partition curtain 12 are controlled to move together along the axial direction of the second roller 14, and at least part of the second part 122 is exposed on the side of the curtain 11.

[0269] You can refer to this article. Figure 4B , Figure 4C , Figure 16 and Figure 17 The curtain device 1 can be in a second unfolded state by controlling the second motor 24 to drive the second roller 14 to move along the axial direction of the second roller 14, and by controlling the third motor 28 to drive the end of the partition curtain 12 away from the second roller 14 to move along the axial direction of the second roller 14. The second motor 24 and the third motor 28 rotate at the same speed.

[0270] In step S40, when the hatch 3 is opened, the second roller 14 and the partition curtain 12 are moved together along the axial direction of the second roller 14, and the partition curtain 12 is retracted along the axial direction of the second roller 14.

[0271] You can refer to this article. Figure 2C , Figure 4Band Figure 4C By controlling the linkage between the cabin door 3 and the partition curtain 12, the partition curtain 12 can be automatically retracted horizontally when the cabin door 3 is opened, so that the curtain device 1 can switch from the second unfolded state to the first unfolded state, so as to provide more space for the user and facilitate the user to enter the cabin 100.

[0272] S50, when the hatch 3 is closed, control the second roller 14 and the partition curtain 12 to move together along the axial direction of the second roller 14, and unfold the partition curtain 12 along the axial direction of the second roller 14.

[0273] You can refer to this article. Figure 2C , Figure 4B and Figure 4C By controlling the linkage between the cabin door 3 and the partition curtain 12, the partition curtain 12 can be automatically controlled to unfold horizontally after the cabin door 3 is closed, so that the curtain device 1 can switch from the first unfolded state to the second unfolded state to provide users with a private space.

[0274] In some examples, the two second reels 14 on both sides can share the same motor so that the two second reels 14 on both sides can operate simultaneously.

[0275] In other examples, a single second roller 14 can be controlled independently. When the hatch 3 is open, the second roller 14 on the side of the open hatch 3 is controlled to move laterally, thus retracting the partition curtain 12 laterally. When the hatch 3 is closed, the second roller 14 on the side of the closed hatch 3 is controlled to move laterally, thus unfolding the partition curtain 12 laterally.

[0276] It should be noted that the above steps S10 to S50 are only an illustration of one control method. In other embodiments, the control method may include more or fewer steps.

[0277] It should be noted that steps S10 to S40 above are the process of unfolding the curtain 11 and the partition curtain 12. The control method may also include the process of retracting the curtain 11 and the partition curtain 12.

[0278] Specifically, when the current state is the second expanded state and the target state is the collapsed state, the control method may include:

[0279] The second roller 14 and the partition curtain 12 are moved together along the axial direction of the second roller 14, with the partition curtain 12 located on the back side of the curtain 11.

[0280] For reference, step S30 above can be seen. This step can be the reverse of step S30.

[0281] Control the first roller 13 to roll up the curtain 11 and the second roller 14 to roll up the partition curtain 12.

[0282] Refer to step S10 above; this step can be the reverse of step S10.

[0283] The execution and storage entities of the above control methods will be introduced next.

[0284] Please see Figure 19 , Figure 19 This is a schematic block diagram of a control device 2000 provided in an embodiment of this application.

[0285] In some embodiments, the control device 2000 may include units that execute the control method described above, and each unit in the control device 2000 may be used to execute the corresponding process of the control method described above.

[0286] For example, the control device 2000 may include an acquisition unit 2001 and a processing unit 2002. When the control device 2000 executes the above control method, the acquisition unit 2001 may be used to acquire the target state, and the processing unit 2002 may be used to execute and control the curtain device 1 to be in the target state.

[0287] It should be understood that the division of units in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. All units of the above device can be implemented entirely through processor-invoked software, entirely through hardware circuits, or partially through processor-invoked software with the remaining parts implemented through hardware circuits.

[0288] In a specific implementation, the acquisition unit 2001 can be implemented by at least one processor or processor-related circuitry, and the processing unit 2002 can be implemented by at least one transceiver or transceiver-related circuitry. In one example, one or more processors can acquire control information. In another example, one or more processors can control the curtain device 1 to be in a target state based on the control information. Exemplarily, in a specific implementation, the control device 2000 can be a controller for the curtain device 1, or it can be a chip or processor 2003 disposed in the controller.

[0289] Please see Figure 20 , Figure 20 This is a schematic block diagram of a control device 2000 provided in another embodiment of this application.

[0290] In some embodiments, the control device 2000 may include a processor 2003, an interface circuit 2004, and a memory 2005. The processor 2003, interface circuit 2004, and memory 2005 are connected via internal interconnection paths. The memory 2005 stores instructions, and the processor 2003 executes the instructions stored in the memory 2005, while the interface circuit 2004 receives / sends certain parameters. Optionally, the memory 2005 may be coupled to the processor 2003 via an interface, or it may be integrated with the processor 2003.

[0291] It should be noted that the aforementioned interface circuit 2004 may include, but is not limited to, transceiver devices such as input / output interfaces, to enable communication between the device and other devices or communication networks. For example, control information can be obtained through the interface circuit 2004, or communication with the motor in the curtain device 1 can be achieved.

[0292] In this embodiment, the processor 2003 is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a type of microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. These logical relationships are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field-programmable gate array (FPGA). In a reconfigurable hardware circuit, the process of the processor 2003 loading a configuration document to configure the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
