[0002] More and more cars are equipped with in-cabin entertainment systems, such as screens for passengers to watch movies. Existing screens are usually stored separately, and need to be manually installed in a specific position on the car when in use. After use, the screen needs to be removed and placed in a storage place such as the trunk. The operation is cumbersome, and the trunk and other storage places are usually placed with other items, which can easily cause damage to the screen and affect the viewing effect. Summary of the invention

[0003] The purpose of the present application is to provide a screen assembly, an optical machine assembly, a projection system, a vehicle and a control method to solve the problem that the screen in the existing automobile is cumbersome to use or store, and is easily damaged when stored together with other items.

[0004] A first aspect of the present application provides a curtain assembly, wherein the curtain assembly is arranged in a vehicle ceiling, and the curtain assembly comprises:

[0005] a first connection structure, wherein the curtain assembly is connected to a body sheet metal in the vehicle ceiling through the first connection structure;

[0006] a first driving mechanism;

[0007] A curtain body is connected to the first driving mechanism, and the curtain is rolled up or extended into the vehicle roof by the driving of the first driving mechanism.

[0008] The curtain assembly provided in the present application does not require additional structures such as hooks to be set on the interior decoration parts or the body beams, nor does it require major changes to the manufacturing process of the body beams or the interior decoration parts. It only requires reserving space between the body sheet metal and the interior decoration parts for setting the curtain assembly, which saves production costs and facilitates the arrangement of the curtain assembly.

[0009] In a possible design, the curtain assembly also includes a first shell, which is arranged in the vehicle roof and connected to the vehicle body sheet metal through the first connecting structure, and the first driving mechanism is arranged in the first shell; the first shell is provided with a first opening, and the curtain body is rolled up or extended from the first shell through the first opening.

[0010] Among them, the first shell can be fixed on the body sheet metal by the cooperation of connecting parts such as bolts, screws, rivets and the like and the connecting holes, thereby facilitating the connection between the curtain assembly and the vehicle roof. At the same time, the first shell can also be used to protect the first driving mechanism and the curtain body to prevent the curtain body from being damaged or contaminated by external objects.

[0011] In a possible design, the curtain assembly further includes a decorative panel connected to the bottom of the curtain body, and the decorative panel is used to close the first opening when the curtain body is stored in the first shell.

[0012] The decorative plate can prevent external impurities, liquids, etc. from entering the first shell and contaminating the first drive mechanism and the screen body. On the other hand, it can also prevent the screen body and other parts from being exposed and affecting the appearance. In addition, the decorative plate also has a certain weight and can be used as a counterweight for the screen. When the screen body is lowered or the screen body is in normal use, the decorative plate can keep the screen body stable during use and improve the viewing experience.

[0013] In a possible design, the curtain body further includes a telescopic bracket, one end of which is disposed on the first shell, the other end of which is connected to the curtain body, and the other end of which is stored in or extended from the first shell as the curtain body moves.

[0014] The telescopic bracket can prevent the screen body from twisting when the vehicle shakes, ensuring the stability of the screen body when in use and improving the viewing experience. In addition, during the process of rolling up or unfolding the screen body, the telescopic bracket can also be extended and retracted to support the screen body during the entire process of rolling up or unfolding the screen body, ensuring that the screen body can be rolled up or unfolded smoothly without wrinkles.

[0015] In a possible design, the first shell is fixed to the body sheet metal via the first connection structure, thereby facilitating the fixation of the first shell and ensuring the reliability of the connection between the first shell and the body sheet metal.

[0016] In a possible design, the first connection structure is an adapter bracket. The use of the adapter bracket can facilitate the installation of the curtain assembly.

[0017] In a possible design, the first connection structure is a connection hole provided on the first shell, so that the first shell can be fixed to the body sheet metal through the cooperation of the connection hole with the connection parts such as bolts, screws, rivets, etc., thereby facilitating the connection between the curtain assembly and the vehicle roof.

[0018] In a possible design, the first driving mechanism includes a motor and a reel, wherein the motor is connected to the reel to drive the reel to rotate; one end of the curtain body is connected to the reel. The coordination of the motor and the reel facilitates the retraction and unfolding of the curtain body.

[0019] In a possible design, the curtain assembly is slidably connected to the body sheet metal along the longitudinal direction of the vehicle via the first connection structure, so that the front and rear position of the curtain assembly can be adjusted, so that passengers can adjust the curtain assembly to a suitable position according to their needs, which can better enhance the viewing experience.

[0020] In a possible design, the curtain assembly includes a second shell, the first driving mechanism is arranged in the second shell, and the curtain body is rolled up or extended from the second shell; the first connecting structure includes a slide rail, a slider and a second driving mechanism; the slide rail is connected to the body sheet metal, the slider is connected to the second shell, and the second shell is slidably connected to the slide rail through the slider; the second driving mechanism is connected to the second shell, and is used to drive the second shell to move along the slide rail.

[0021] Among them, the second driving mechanism can be a motor or a cylinder, etc. The second driving mechanism can provide a forward or backward force to the second shell, so that the second shell can achieve relative sliding through the cooperation of the slide rail and the slider, thereby realizing the adjustment of the position of the curtain assembly and facilitating control.

[0022] A second aspect of the present application further provides an optical-mechanical assembly, comprising:

[0023] a second connection structure;

[0024] An optical machine body, wherein the optical machine body is disposed in a vehicle roof, and the optical machine body is connected to a vehicle body sheet metal in the vehicle roof through the second connection structure;

[0025] A lens is connected to the optical machine body, the lens extends out of the vehicle roof, and the lens is used to project light and shadow onto the curtain body in the curtain assembly provided in the first aspect of the present application.

[0026] The optical machine assembly provided by the present application is arranged inside the vehicle roof so that only the lens protrudes from the roof, and the lens is small in size, which can save a lot of space inside the vehicle compared to the existing optical machine. In addition, the lens is located on the vehicle roof, so that the lens can be located above the passenger's head, and the light emitted by the lens will not affect the passenger's eyes, so that the passenger can have a better viewing experience.

[0027] In a possible design, the lens is arranged at the bottom of the optical machine body along the thickness direction of the vehicle roof. For a vehicle with a skylight glass and a sunshade, the sunshade is arranged inside the vehicle roof. If the lens is on the side of the optical machine body, the lens will be blocked by the sunshade, resulting in the projection of the lens not being effectively projected onto the curtain body. In this application, the lens is arranged at the bottom of the optical machine body and protrudes from the interior decoration of the vehicle roof, so that there is no sunshade blocking the projection direction of the lens, thereby ensuring the effectiveness of the lens projection.

[0028] In a possible design, along the longitudinal direction of the vehicle, the lens is arranged at one end of the optical machine body facing the curtain assembly. The interior trim of the vehicle roof may be designed with an inclined surface near the rear of the vehicle, and the inclined surface may have a hole along the longitudinal direction of the vehicle. Under this design, the lens may be arranged on the side of the optical machine body so that the lens can be aligned with the hole on the inclined surface of the interior trim and can project light and shadow onto the curtain body through the hole. In this way, the optical machine assembly can be arranged in the vehicle roof without the lens protruding from the bottom of the optical machine body to the vehicle roof, thereby saving space above the passengers' heads.

[0029] In a possible design, the optical machine body includes a light emitting module, an air inlet channel and an air outlet channel, and the lens is connected to the light emitting module; along the thickness direction perpendicular to the vehicle roof, the air inlet channel and the air outlet channel are respectively arranged on opposite sides of the light emitting module.

[0030] Among them, by setting an air inlet channel and an air outlet channel on both sides of the light-emitting module, the wind entering from the air inlet channel can pass through the heating module and then flow out from the air outlet channel, thereby taking away the heat on the heating module, achieving heat dissipation and ensuring the normal operation of each component in the heating module.

[0031] In a possible design, the optical machine body further includes a housing, the light emitting module is disposed in the housing, and the air inlet channel and the air outlet channel are respectively formed on both sides of the light emitting module in the housing. The air inlet channel or air outlet channel for air inlet or air outlet is directly formed on both sides of the heating module by utilizing the structure of the housing itself, thereby eliminating the need to separately arrange an air inlet duct or an air outlet duct, thereby simplifying the structure.

[0032] In a possible design, the shell is provided with an air inlet and an air outlet, the air inlet is connected to the air inlet channel, and the air outlet is connected to the air outlet channel; along the thickness direction of the vehicle roof, the opening directions of the air inlet and the air outlet are both toward the inner side of the vehicle roof. Through the air inlet and the air outlet, the environment inside the shell can be connected to the environment inside the vehicle, so that the air flow flowing in the vehicle can circulate through the air inlet, the air inlet channel, the heating module, the air outlet channel and the air outlet in sequence, thereby achieving effective heat dissipation of the heating module. In addition, by making the opening directions of the air inlet and the air outlet both face the inner side of the vehicle roof, it is possible to avoid the air inlet and the air outlet being blocked by the sunshade and its components, thereby improving the heat dissipation effect.

[0033] In a possible design, the optical-mechanical assembly further includes a fan, and the fan is disposed in the air inlet passage.

[0034] Among them, the fan can blow air to the heating module. When the fan blows air, negative pressure will be generated in the air inlet channel, so that the airflow in the car can enter the air inlet channel from the air inlet and be further blown to the heating module by the fan, thereby achieving continuous heat dissipation of the heating module.

[0035] In a possible design, the second connection structure is an adapter bracket. The adapter bracket can be used to facilitate the installation of the alignment machine body.

[0036] In a possible design, the second connection structure is a connection hole provided on the housing, so that the optical machine body can be fixed on the body sheet metal through the cooperation of the connection holes with the connection parts such as bolts, screws, rivets, etc., which facilitates the assembly and disassembly of the optical machine body and also improves the reliability of fixing the optical machine body on the body sheet metal.

[0037] The third aspect of the present application also provides a projection system, which includes the screen assembly provided by the first aspect of the present application and the optomechanical assembly provided by the second aspect of the present application, and the optomechanical assembly projects light and shadow onto the screen body in the screen assembly through the lens.

[0038] Among them, the relevant schemes and technical effects of the curtain assembly and the optical-mechanical assembly are the same as described above and will not be repeated here.

[0039] The fourth aspect of the present application also provides a vehicle, which includes the projection system provided in the third aspect of the present application, and the vehicle also includes a vehicle roof, the vehicle roof includes body sheet metal and interior decoration parts, and a storage space is formed between the interior decoration parts and the body sheet metal. The projection device is at least partially arranged in the storage space.

[0040] In a possible design, the curtain assembly is fixed to the vehicle body sheet metal.

[0041] In a possible design, the body sheet metal includes a first crossbeam and a second crossbeam, the first crossbeam is located in the middle of the vehicle roof, the curtain assembly is connected to the first crossbeam; the second crossbeam is located at the rear of the vehicle roof, and the optical-mechanical assembly is fixed to the second crossbeam. Thus, the reliability of fixing the curtain assembly and the optical-mechanical assembly can be achieved, and effective imaging between the optical-mechanical assembly and the curtain assembly can be achieved.

[0042] In a possible design, the vehicle further includes a sunshade bracket and a sunshade, the sunshade bracket is connected to the body sheet metal, the sunshade bracket is provided with a first sliding portion, and the sunshade is slidably connected to the sunshade bracket via the first sliding portion; the curtain assembly is slidably connected to the body sheet metal, and the curtain assembly is located below the sunshade. By arranging the curtain assembly below the sunshade, the curtain assembly can be prevented from interfering with the sunshade when in use, so that the curtain assembly and the sunshade can be used independently.

[0043] In a possible design, the sunshade bracket is provided with a second sliding portion, and the curtain assembly is slidably connected to the sunshade bracket via the second sliding portion.

[0044] The curtain assembly and the sunshade curtain can share a sunshade curtain bracket, so there is no need to design a bracket separately for the curtain assembly, which simplifies the structure and facilitates the setting of the curtain assembly.

[0045] In a possible design, a second opening is provided on the interior decoration component, and a decorative panel is provided on the curtain body, and the decorative panel is used to close the second opening when the curtain body is stored in the accommodating space.

[0046] The fifth aspect of the present application further provides a control method, which is used to control the rolling or unfolding of the curtain body in the curtain assembly provided in the first aspect of the present application, and the control method includes:

[0047] Detecting whether the curtain body is in a rolled-up state;

[0048] If yes, detecting whether the backrest position of the front seat of the vehicle coincides with the deployment path of the curtain body;

[0049] If yes, the curtain body is controlled to stop unfolding.

[0050] In a possible implementation, the detecting whether the backrest position of the front seat of the vehicle coincides with the deployment path of the curtain body specifically includes:

[0051] Obtaining the backrest position according to the displacement and backrest angle of the front seat;

[0052] Whether the position of the curtain body and the position of the backrest overlap along the unfolding direction of the curtain body is determined according to the position of the curtain body and the position of the backrest.

[0053] In a possible implementation, if the result of detecting whether the backrest position of the front seat of the vehicle coincides with the deployment path of the curtain body is no, the control method further includes:

[0054] Detecting whether the curtain body interferes with an object during the unfolding process;

[0055] If yes, the curtain body is controlled to stop unfolding.

[0056] In a possible implementation, if the result of detecting whether the backrest position of the front seat of the vehicle coincides with the deployment path of the curtain body is no, the control method further includes:

[0057] Detecting whether the distance between the backrest position of the front seat of the vehicle and the curtain body along the longitudinal direction of the vehicle is greater than a set value;

[0083] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0084] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0085] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0086] At present, more and more cars are equipped with in-cabin entertainment systems, such as screens for passengers to watch movies. Existing screens are generally stored separately. When in use, the screen needs to be manually installed at a specific position on the car. After use, the screen needs to be removed and placed in a storage place such as a trunk. For example, the car may have a hook, and the screen can be manually hung on the hook when in use. After use, the screen can be removed from the hook for storage, which is cumbersome. In addition, the screen is generally stored in a storage place such as the trunk of the car. However, such a storage place is usually placed with other items, and it is easy to cause damage or contamination to the screen for certain angular items, affecting the viewing effect.

[0087] The embodiment of the present application provides a screen assembly 1, an optical machine assembly 2, a projection system and a vehicle 100, such as Figure 1As shown, the vehicle 100 may be, but is not limited to, a sport utility vehicle (SUV), a multiple purpose vehicle (MPV), a sedan, a motorhome, a van, a bus, a truck, etc.

[0088] like Figure 1 As shown, the projection system can be arranged in the roof of the vehicle 100, and the projection system includes the screen assembly 1 and the optical-mechanical assembly 2. The light and shadow projected by the optical-mechanical assembly 2 can be imaged on the screen assembly 1. When in use, the screen body 11 used for imaging in the screen assembly 1 can be controlled to extend from the vehicle roof 110 and can be opposite to the optical-mechanical assembly 2, so that the light and shadow projected by the optical-mechanical assembly 2 can be imaged on the screen body 11. After use, the screen body 11 can be controlled to be stored in the vehicle roof 110 again, so that there is no need to manually install or store the screen assembly 1, the operation is convenient, and the screen assembly 1 can be prevented from being damaged or contaminated by other objects.

[0089] Specifically, Figures 2 to 4 As shown, the curtain assembly 1 includes a first connection structure 16, a first drive mechanism 12 and a curtain body 11. The curtain assembly 1 can be connected to the body sheet metal 111 in the vehicle ceiling 110 through the first connection structure 16. The curtain body 11 is connected to the first drive mechanism 12, and the curtain is rolled up or extended into the vehicle ceiling 110 by the drive of the first drive mechanism 12. Among them, the first drive mechanism 12 can be connected to the main control system signal in the vehicle 100. When the main control system sends a first signal, the first drive mechanism 12 is started to control the curtain body 11 to extend from the vehicle ceiling 110 for passengers to watch movies; when the main control system sends a second signal, the curtain body 11 can be retracted into the vehicle ceiling 110. Specifically, the driver or passenger can manually operate the control panel or dedicated switch of the vehicle 100 to make the main control system send the above-mentioned first signal or second signal. Of course, a remote controller dedicated to controlling the lifting and lowering of the curtain body 11 can also be configured, and the lifting and lowering and retracting and extending of the curtain body 11 can be controlled by the remote control signal sent by the remote controller.

[0090] Therefore, the present application integrates the curtain assembly 1 into the vehicle ceiling 110, which not only facilitates the operation, but also realizes the storage management of the curtain assembly 1, avoids damage or contamination of the curtain assembly 1 by other objects, and improves the user experience.

[0091] Among them, Figure 2 and Figure 3As shown, the vehicle roof 110 may include a body sheet metal 111 and an interior trim 115. The interior trim 115 is connected to the inner side of the body sheet metal 111. As part of the interior trim of the entire vehicle, the interior trim 115 has a lower rigidity than the body sheet metal 111. It can cover the inner side of the body beam and can shield the sheet metal from the inside of the vehicle 100. On the one hand, it can prevent the driver or passenger from hitting the sheet metal and getting injured, and on the other hand, it can enhance the visual effect and the texture of the vehicle 100. The body sheet metal 111 is a metal part with relatively high rigidity, which can be used as the skeleton of the vehicle roof 110. The connection of the curtain assembly 1 to the body sheet metal 111 can ensure the reliability of the connection of the curtain assembly 1. In this embodiment, a receiving space 116 can be formed between the interior trim 115 and the body sheet metal 111, and the curtain assembly 1 can be arranged in the receiving space 116, so that the curtain assembly 1 can be stored separately, and damage to the curtain assembly 1 by other objects can be avoided.

[0092] In this embodiment, there is no need to set additional structures such as hooks on the interior trim 115 or the vehicle body beam, nor is there any need to make major changes to the manufacturing process of the vehicle body beam or the interior trim 115. It is only necessary to reserve space between the vehicle body sheet metal 111 and the interior trim 115 for setting the curtain assembly 1, which saves production costs and facilitates the arrangement of the curtain assembly 1.

[0093] Specifically, Figure 3 and Figure 4 As shown, in one embodiment, the curtain assembly 1 also includes a first shell 13, the first shell 13 is arranged in the vehicle roof 110, and the first shell 13 is connected to the vehicle body sheet metal 111 through a first connecting structure 16, the first driving mechanism 12 is arranged in the first shell 13, the first shell 13 is provided with a first opening, and the curtain body 11 is rolled up or extended from the first shell 13 through the first opening.

[0094] The first shell 13 can be disposed as a whole in the accommodation space 116 between the body sheet metal 111 and the interior decoration 115. The first connection structure 16 can be a connection hole formed on the first shell 13, so that the first shell 13 can be fixed on the body sheet metal 111 through the cooperation of the connection holes with the connection parts such as bolts, screws, rivets, etc., thereby facilitating the connection between the curtain assembly 1 and the vehicle ceiling 110. At the same time, the first shell 13 can also be used to protect the first driving mechanism 12 and the curtain body 11, preventing the curtain body 11 from being damaged or contaminated by external objects. Among them, the first opening of the first shell 13 faces the interior of the vehicle 100, so that the curtain body 11 can be raised and lowered and retracted through the first opening in the height direction of the vehicle 100.

[0095] In addition, the first connection structure 16 can also be an adapter bracket, and the entire curtain assembly 1 can be connected to the body sheet metal 111 through the adapter bracket, and specifically, one end of the adapter bracket can be connected to the first shell 13, and the other end of the adapter bracket can be connected to the body sheet metal 111. The use of the adapter bracket can facilitate the installation of the curtain assembly 1, and the adapter bracket can be designed according to the installation environment inside the vehicle ceiling 110, which is not limited in this embodiment.

[0096] Specifically, Figure 3 and Figure 4 As shown, the screen assembly 1 further includes a decorative plate 14, which is connected to the bottom of the screen body 11, and is used to close the first opening when the screen body 11 is stored in the first shell 13. The shape of the decorative plate 14 can be equivalent to the shape of the first opening. For example, the first opening can be a rectangular hole, and the shape of the decorative plate 14 can also be a rectangle. When the screen body 11 is stored in the first shell 13, the decorative plate 14 can close the first opening, thereby preventing external impurities, liquids, etc. from entering the first shell 13 and contaminating the first drive mechanism 12 and the screen body 11, and on the other hand, it can also prevent the screen body 11 and other components from being exposed and affecting the appearance. In addition, the decorative plate 14 also has a certain weight and can be used as a counterweight for the screen. When the screen body 11 is lowered, or when the screen body 11 is in normal use, the decorative plate 14 can keep the screen body 11 stable during use, thereby improving the viewing experience.

[0097] It is understandable that if Figure 4 As shown, the interior part 115 may be provided with a second opening 115a, which is aligned and connected with the first opening, and the curtain body 11 in the first shell 13 may extend out of the interior part 115 through the first opening and the second opening 115a in sequence, and unfold to form an image. In the state where the curtain body 11 is stored in the accommodation space 116, the decorative plate 14 may close the second opening 115a, so that the curtain assembly 1 may also be closed in the accommodation space 116 between the interior part 115 and the body sheet metal 111. In the state where the curtain body 11 is stored in the accommodation space 116, the decorative plate 14 may be embedded in the second opening 115a, so as to be spliced ​​with the edge of the second opening 115a, so that the decorative plate 14 and the side of the interior part 115 facing the interior of the vehicle 100 are flush, so as to improve the appearance of the interior of the vehicle 100.

[0098] Specifically, Figure 4As shown, the curtain body 11 further includes a telescopic bracket 15, one end of which is disposed on the first shell 13, and the other end of the telescopic bracket 15 is connected to the curtain body 11, and the other end of the telescopic bracket 15 can be stored or extended from the first shell 13 as the curtain body 11 moves. The other end of the telescopic bracket 15 can be directly connected to the curtain body 11, or can be indirectly connected to the curtain body 11 through a structure such as a decorative plate 14.

[0099] It is understandable that the screen body 11 is relatively soft and is prone to twisting or wrinkling during the process of unfolding or reeling in, and when the vehicle 100 is shaking, which will reduce the viewing experience. To this end, in this embodiment, the telescopic bracket 15 can be supported on the back of the screen body 11, so as to prevent the screen body 11 from twisting when the vehicle 100 is shaking, and can ensure the stability of the screen body 11 in use, thereby improving the viewing experience. In addition, during the process of rolling or unfolding the screen body 11, the telescopic bracket 15 can also support the screen body 11 throughout the entire process of rolling or unfolding the screen body 11 by telescoping, ensuring that the screen body 11 can be smoothly rolled or unfolded without wrinkling.

[0100] Among them, Figure 5 As shown, the telescopic bracket 15 may include a plurality of segments 151 , and the plurality of segments 151 may be rotatably connected to each other so that the plurality of segments 151 may be folded or unfolded, thereby realizing the “telescopic” of the telescopic bracket 15 .

[0101] Specifically, Figure 6 As shown, the first driving mechanism 12 includes a motor 121 and a reel 122, the motor 121 is connected to the reel 122, and is used to drive the reel 122 to rotate, and one end of the curtain body 11 is connected to the reel 122. When the motor 121 drives the reel 122 to rotate, the curtain body 11 can be wound onto the reel 122, or released from the reel 122 and flattened. Therefore, through the cooperation of the motor 121 and the reel 122, the curtain body 11 can be easily retracted and extended.

[0102] In addition, the screen assembly 1 can be fixed in the vehicle ceiling 110, and the screen body 11 can be directly controlled to be retracted and extended when in use. However, for vehicles 100 with a small space, such as compact cars and SUVs, the distance between the front seats 117 and the rear seats 118 is small. For passengers with larger heights and physiques, the screen body 11 is close to the human eyes, and the viewing experience cannot be optimal.

[0103] For this reason, Figure 7 and Figure 8As shown, in another embodiment provided by the present application, the curtain assembly 1 can be slidably connected to the body sheet metal 111 along the longitudinal direction Y of the vehicle 100 through the first connecting structure 16, so that the front and rear position adjustment of the curtain assembly 1 can be realized, so that the passengers can adjust the curtain assembly 1 to a suitable position according to their needs, which can better enhance the viewing experience.

[0104] Specifically, in this embodiment, for the convenience of explanation, the population is divided into a tall population and a short population, with the tall population accounting for 95% and the short population accounting for 5%.

[0105] Among them, Fig. 9 As shown, when the driver or passenger sitting in the front seat 117 is 95% of the tallest person, a sufficiently large distance needs to be maintained between the front seat 117 and the dashboard. At this time, the front seat 117 cannot be too close to the dashboard, and the curtain assembly 1 cannot slide forward a large distance, otherwise it will hit the backrest 117a of the front seat 117. At this time, the distance between the curtain assembly 1 and the rear passengers is smaller.

[0106] like Fig.10 As shown, when the driver or passenger sitting in the front seat 117 is one of the 5% short people, the space between the front seat 117 and the dashboard does not need to be very large, and the front seat 117 can be adjusted to be close to the dashboard to increase the distance between the front seat 117 and the rear seat 118. At this time, the curtain assembly 1 can be slid forward through the first connecting structure 16, and the maximum sliding position can be the position where the curtain body 11 does not interfere with the front seat 117. In this way, the viewing distance between the curtain body 11 and the rear passengers can be increased, thereby improving the viewing experience.

[0107] The position adjustment of the screen assembly 1 can be performed while driving or while parking, and will not be affected by the driving state. The position of the screen assembly 1 can be adjusted as needed, thereby improving the viewing experience.

[0108] Specifically, Fig.11 As shown, when the vehicle 100 is in the parking mode, the driver or the passenger of the front seat 117 may not be in the vehicle. At this time, the front seat 117 can be further adjusted toward the dashboard, and the backrest 117a of the front seat 117 can be tilted forward. At this time, more space can be provided for the forward adjustment of the curtain assembly 1, and the distance between the passenger of the rear seat 118 and the curtain body 11 can be further increased, providing a larger choice space for different passengers.

[0109] Specifically, Figure 7 and Figure 8As shown, the curtain assembly 1 may include a second shell 17, the first driving mechanism 12 is disposed in the second shell 17, and the curtain body 11 is rolled up or extended from the second shell 17. The second shell 17 may be disposed as a whole in the accommodation space 116 between the body sheet metal 111 and the interior decoration 115, so as to protect the first driving mechanism 12 and the curtain body 11, and prevent the curtain body 11 from being damaged or contaminated by external objects.

[0110] The first connection structure 16 may include a slide rail, a slider, and a second drive mechanism. The slide rail may be connected to the body sheet metal 111. The "connection" may be a direct connection or an indirect connection. For example, the slide rail may be directly fixed to the body sheet metal 111 by a connection member such as a bolt or a rivet, or may be indirectly connected to the body sheet metal 111 by a structure such as a bracket. The slider is connected to the second housing 17. The second housing 17 is slidably connected to the slide rail through the slider. The second drive mechanism is connected to the second housing 17 to drive the second housing 17 to move along the slide rail.

[0111] The second driving mechanism can be a motor 121 or a cylinder, etc. The second driving mechanism can provide a forward or backward force to the second shell, so that the second shell can slide relative to each other through the cooperation of the slide rail and the slider, thereby adjusting the position of the curtain assembly 1 and facilitating control. The second driving mechanism can be connected to the main control system signal of the vehicle 100, or the second driving mechanism can be turned on or off by a switch, or a signal connection can be established with the second driving mechanism by a remote controller, which is not limited in this embodiment.

[0112] Among them, Figure 2 As shown, the body sheet metal 111 may include a crossbeam 111b and a longitudinal beam 111a, wherein the crossbeam 111b is a beam extending along the transverse direction X of the vehicle 100, and the longitudinal beam 111a is a beam extending along the longitudinal direction Y of the vehicle 100. The slide rail may be provided on the longitudinal beam 111a, and the slide rail may extend along the longitudinal beam 111a, so that the curtain assembly 1 can slide forward and backward, and the reliability of the slide rail fixation can also be ensured.

[0113] like Fig.12 and Fig.13 As shown, the present application further provides an optomechanical assembly 2 , which has a certain distance from the screen assembly 1 , so that the light and shadow projected by the optomechanical assembly 2 can be imaged on the screen body 11 of the screen assembly 1 .

[0114] It should be noted that the existing optical machine has a lens 22 in the length or width direction thereof, and the optical machine is generally placed directly behind the rear seat 118, but the optical machine is prone to move or even fall when the vehicle 100 is bumpy, and the light emitted by the optical machine needs to pass through the position between the two rear seats, which sometimes affects the passengers in the rear row close to the optical machine, causing great inconvenience to the passengers.

[0115] In this embodiment, Fig.12 and Fig.13 As shown, the optical machine assembly 2 includes a second connection structure 23, an optical machine body 21 and a lens 22. The optical machine body 21 is disposed in the vehicle roof 110, and the optical machine body 21 is connected to the vehicle body sheet metal 111 in the vehicle roof 110 through the second connection structure 23. The lens 22 is connected to the optical machine body 21, and the lens 22 extends out of the vehicle roof 110. The lens 22 is used to project light and shadow onto the curtain body 11 provided in any embodiment of the present application, and can form an image on the curtain body 11.

[0116] The optical machine assembly 2 provided in the embodiment of the present application is arranged in the vehicle ceiling, and only the lens 22 protrudes from the ceiling. The lens 22 is relatively small in size, and a large amount of space in the vehicle can be saved compared to the existing optical machine. In addition, the lens 22 is located in the vehicle ceiling 110, so that the lens 22 can be located above the passenger's head, and the light emitted by the lens 22 will not affect the passenger's eyes, so that the passenger can have a better viewing experience.

[0117] Specifically, in one embodiment, Fig.12 and Fig.13 As shown, the lens 22 is arranged at the bottom of the optical machine body 21 along the thickness direction of the vehicle roof 110. Among them, for the vehicle 100 with the skylight glass 112 and the sunshade 114, the sunshade 114 is arranged in the vehicle roof 110. If the lens 22 is on the side of the optical machine body 21, the lens 22 will be blocked by the sunshade 114, resulting in that the projection of the lens 22 cannot be effectively projected onto the curtain body 11. In this application, by setting the lens 22 at the bottom of the optical machine body 21 and protruding from the interior decoration 115 of the vehicle roof 110, there is no blocking of the sunshade 114 in the projection direction of the lens 22, thereby ensuring the effectiveness of the projection of the lens 22.

[0118] In addition, in another embodiment, Fig.14 and Fig.15As shown, along the longitudinal direction of the vehicle 100, the lens 22 is arranged at one end of the optical machine body 21 facing the curtain assembly 1. The interior trim 115 of the vehicle ceiling 110 may be designed with an inclined surface 115b at a position close to the rear of the vehicle, and the inclined surface 115b may be opened along the longitudinal direction Y of the vehicle 100. Under this design, the lens 22 may be arranged on the side of the optical machine body 21, so that the lens 22 can be aligned with the opening on the inclined surface 115b of the interior trim 115, and light and shadow can be projected onto the curtain body 11 through the opening. In this way, the optical machine assembly 2 can be arranged in the vehicle ceiling 110 without the lens 22 protruding from the bottom of the optical machine body 21 out of the vehicle ceiling 110, thereby saving space above the passengers' heads.

[0119] In one embodiment, the second connection structure 23 may be an adapter bracket. The optical machine body 21 may be connected to the vehicle body sheet metal 111 through the adapter bracket, specifically, one end of the adapter bracket may be connected to the optical machine body 21, and the other end of the adapter bracket may be connected to the vehicle body sheet metal 111. The use of the adapter bracket may facilitate the installation of the optical machine body 21, and the adapter bracket may be designed according to the installation environment inside the vehicle roof 110, which is not limited in this embodiment.

[0120] In another embodiment, the second connection structure 23 can also be a connection hole set on the optical machine body 21, so that the optical machine body 21 can be fixed to the vehicle body sheet metal 111 through the cooperation of connecting parts such as bolts, screws, rivets, etc. and the connection hole, which facilitates the disassembly and assembly of the optical machine body 21 and also improves the reliability of fixing the optical machine body 21 on the vehicle body sheet metal 111.

[0121] Specifically, Fig.13 As shown, the optical machine body 21 includes a light emitting module, an air inlet channel 212 and an air outlet channel 213, and the lens 22 is connected to the light emitting module. Along the thickness direction perpendicular to the vehicle roof 110, the air inlet channel 212 and the air outlet channel 213 are respectively arranged on opposite sides of the light emitting module. Among them, the light emitting module integrates heat-generating components such as chips and circuit boards. Since the optical machine body 21 is arranged in a relatively closed space in the vehicle roof 110, in order to make each heat-generating component in the light emitting module have a good heat dissipation effect, the air inlet channel 212 and the air outlet channel 213 can be arranged on both sides of the light emitting module. The wind entering from the air inlet channel 212 can pass through the heating module and then flow out from the air outlet channel 213, thereby taking away the heat on the heating module, achieving heat dissipation, and ensuring the normal operation of each component in the heating module.

[0122] Specifically, Fig.13As shown, the optical machine body 21 also includes a shell 211, and the light-emitting module is arranged in the shell 211. The shell 211 is formed with an air inlet channel 212 and an air outlet channel 213 on both sides of the light-emitting module. The shell 211 can protect the light-emitting module and also facilitate the installation and fixation of the optical machine assembly 2 in the vehicle ceiling 110. Specifically, the shell 211 can be fixed to the body sheet metal 111 through a second connecting structure 23. The second connecting structure 23 can be a connecting hole formed on the shell 211. The connecting hole can be used to fix the shell 211 to the body sheet metal 111 by cooperating with connecting parts such as bolts, screws, and rivets, so as to facilitate operation. In addition, the structure of the shell 211 itself is used to directly form an air inlet channel 212 or an air outlet channel 213 for air intake or air outlet on both sides of the heating module, so that there is no need to arrange an air inlet pipe or an air outlet pipe separately, thereby simplifying the structure.

[0123] Specifically, Fig.13 As shown, in the design where the lens 22 is disposed at the bottom of the optical machine body 21, the housing 211 is provided with an air inlet 212a and an air outlet 213a, the air inlet 212a is connected to the air inlet channel 212, and the air outlet 213a is connected to the air outlet channel 213. Along the thickness direction of the vehicle roof 110, the opening directions of the air inlet 212a and the air outlet 213a are both toward the inner side of the vehicle roof 110.

[0124] Through the air inlet 212a and the air outlet 213a, the environment inside the shell 211 can be connected with the environment inside the vehicle 100, so that the air flow flowing in the vehicle can circulate through the air inlet 212a, the air inlet channel 212, the heating module, the air outlet channel 213 and the air outlet 213a in sequence, thereby achieving effective heat dissipation of the heating module.

[0125] In addition, for a vehicle 100 with a sunshade bracket 113 integrated in the vehicle roof 110, the sunshade bracket 113 and its related components will occupy a large space in the vehicle roof 110. If the heat dissipation openings of the optical machine body 21 are arranged on both sides of the optical machine body 21 along the longitudinal direction Y of the vehicle 100, the heat dissipation openings will be blocked by the sunshade bracket 113 and its related components, resulting in that the heat at the heat dissipation openings cannot be diffused in time, and the hot air flow will accumulate near the optical machine body 21, causing the temperature of the optical machine body 21 to rise, affecting the performance of the optical machine assembly 2. In this embodiment, if Fig.13 As shown, by making the air inlet 212a and the air outlet 213a open toward the inside of the vehicle roof 110, the air inlet 212a and the air outlet 213a can be prevented from being blocked by the sunshade bracket 113 and its components, thereby improving the heat dissipation effect.

[0126] In addition, if Fig.14As shown, in the design where the lens 22 is arranged on the side of the optical machine body 21, the air inlet can be located on the side of the optical machine body 21, and can be aligned with and connected to the opening on the inclined surface 115b of the interior decoration part 115, that is, the opening on the inclined surface 115b can be used as a hole for light and shadow projection, and can also be used as a hole for air flow, that is, the air flow can enter the interior of the optical machine body 21 through the opening on the inclined surface 115b and the air inlet in turn to dissipate the heat of the heat module.

[0127] Specifically, Fig.13 As shown, the optical-mechanical assembly 2 also includes a fan 214, and the fan 214 is disposed in the air inlet channel 212. The fan 214 can blow air toward the heating module. When the fan 214 blows air, a negative pressure is generated in the air inlet channel 212, so that the airflow in the vehicle can enter the air inlet channel 212 from the air inlet 212a, and is further blown toward the heating module by the fan 214, so as to achieve continuous heat dissipation of the heating module.

[0128] The embodiment of the present application further provides a projection system, which includes the screen assembly 1 and the optical-mechanical assembly 2 provided in any embodiment of the present application, and the optical-mechanical assembly 2 projects light and shadow onto the screen body 11 in the screen assembly 1 through the lens 22. The relevant schemes and technical effects of the screen assembly 1 and the optical-mechanical assembly 2 are the same as those described above, and will not be repeated here.

[0129] In addition, the embodiment of the present application further provides a vehicle 100, which can be the various different vehicle types described above. For ease of description, the present embodiment describes the vehicle 100 as a two-row four-seat vehicle 100.

[0130] As mentioned above, the vehicle roof 110 includes a body sheet metal 111 and an interior trim 115, wherein the interior trim 115 is connected to the inner side of the body sheet metal 111. Figure 2 As shown, the body sheet metal 111 of the vehicle 100 may specifically include a first cross beam 111b1 and a second cross beam 111b2, wherein the first cross beam 111b1 is located in the middle of the vehicle roof 110, and the curtain assembly 1 is connected to the first cross beam 111b1. The second cross beam 111b2 is located at the rear of the vehicle roof 110, and the optical machine body 21 is fixed to the second cross beam 111b2. For a two-row four-seat vehicle 100, the first cross beam 111b1 may be located in the area between the front and rear rows of seats, and the second cross beam 111b2 may be located in the area behind the rear seats 118.

[0131] When the curtain assembly 1 is immovable, the curtain assembly 1 can be fixed to the first crossbeam 111b1, and can be fixed to the first crossbeam 111b1 by bolts, screws, rivets and other connecting parts. When the curtain assembly 1 is movable, the curtain assembly 1 can be slidably connected to the first crossbeam 111b1. The optical machine body 21 can also be fixed to the second crossbeam 111b2 by bolts, screws, rivets and other connecting parts, so as to ensure the reliability of fixing the optical machine body 21.

[0132] Of course, for a vehicle 100 with more than four seats, such as an eight-seat or ten-seat vehicle 100, the first cross beam 111b1 may also be located in the middle of the vehicle roof 110, or may also be located at a position such as 1 / 3 or 2 / 3 of the longitudinal direction Y of the vehicle 100, and the second cross beam 111b2 may also be located at the rear of the vehicle roof 110, or at other positions that are kept a certain distance from the curtain assembly 1.

[0133] As a specific implementation method, Figure 6 As shown, the vehicle 100 further includes a sunshade bracket 113 and a sunshade bracket 113, the sunshade bracket 113 is connected to the body sheet metal 111, a first sliding portion 113a is provided on the sunshade bracket 113, and the sunshade bracket 113 is slidably connected to the sunshade bracket 113 through the first sliding portion 113a; the curtain assembly 1 is slidably connected to the body sheet metal 111, and the curtain assembly 1 is located below the sunshade bracket 113. For the vehicle 100 provided with the sunshade bracket 113 and the sunshade bracket 113, a skylight glass 112 is provided on the vehicle roof 110, when the sunshade bracket 113 is slid open through the first sliding portion 113a, external light can be irradiated to the interior of the vehicle 100 through the skylight glass 112, and when the sunshade bracket 113 is slid closed through the first sliding portion 113a, external light can be blocked from passing through the skylight glass 112, thereby achieving the purpose of sunshading.

[0134] Among them, the curtain assembly 1 is arranged below the sunshade bracket 113, so that the curtain assembly 1 can avoid interference with the sunshade bracket 113 when in use, so that the curtain assembly 1 and the sunshade bracket 113 can be used independently.

[0135] In one embodiment, the curtain assembly 1 can be slidably connected to the vehicle body sheet metal 111 via a bracket, and the bracket and the sunshade bracket 113 bracket can be two different brackets.

[0136] In another embodiment, if Figure 6As shown, the sunshade bracket 113 can be provided with a second sliding portion 113b, and the curtain assembly 1 is slidably connected to the sunshade bracket 113 via the second sliding portion 113b. In this embodiment, the curtain assembly 1 and the sunshade bracket 113 can share a sunshade bracket 113, so there is no need to design a separate bracket for the curtain assembly 1, which simplifies the structure and facilitates the setting of the curtain assembly 1.

[0137] like Fig.16 As shown, the embodiment of the present application further provides a control method, which can be used to control the curtain body 11 in the curtain assembly 1 provided in any embodiment of the present application to be rolled up or unfolded. In this embodiment, the control method is used to control the curtain assembly 1 in a two-row four-seat vehicle 100 as an example for description. The control method includes the following steps:

[0138] Step S1, detecting whether the curtain body 11 is in a rolled-up state; if yes, proceeding to step S2.

[0139] The rolled-up state refers to a state in which the curtain body 11 is stored in the vehicle ceiling 110 .

[0140] Step S2, detecting whether the position of the backrest 117a of the front seat 117 of the vehicle 100 coincides with the unfolding path of the curtain body 11; if yes, proceeding to step S3.

[0141] Step S3, controlling the curtain body 11 to stop unfolding.

[0142] It is understandable that in order to facilitate rear passengers to watch movies using the curtain assembly 1, the curtain assembly 1 is located behind the front seat 117 of the vehicle 100. The front seat 117 of the vehicle 100 can be adjusted forward and backward according to the needs of the passengers, and its backrest 117a can also be adjusted in angle to allow the passengers to have a comfortable sitting posture. The forward and backward adjustment of the front seat 117 or the adjustment of the inclination of the backrest 117a will cause the distance between the backrest 117a and the curtain assembly 1 in the longitudinal direction Y of the vehicle 100 to change. If the backrest 117a of the front seat 117 is located directly below the curtain assembly 1, that is, it blocks the downward unfolding path of the curtain body 11, which will cause the curtain body 11 to interfere with the backrest 117a. At this time, the curtain body 11 can be controlled to stop unfolding. At this time, if you want to continue to use the curtain assembly 1 to watch movies, you can let the front passenger adjust the seat posture to move the front seat 117 away from the downward unfolding path of the curtain body 11.

[0143] If the backrest 117a of the front seat 117 does not block the downward unfolding path of the curtain body 11, the curtain body 11 can be unfolded downward normally without interference.

[0144] Specifically, Fig.17As shown, in step S2, detecting whether the position of the backrest 117a of the front seat 117 of the vehicle 100 coincides with the unfolding path of the curtain body 11 specifically includes:

[0145] Step S21 : obtaining the position of the backrest 117 a according to the displacement of the front seat 117 and the angle of the backrest 117 a .

[0146] A Hall or position sensor may be provided near the front seat 117 to detect the displacement of the seat and the angle of the backrest 117 a , so that the position of the backrest 117 a may be obtained according to the displacement of the front seat 117 and the angle of the backrest 117 a .

[0147] Step S22: determine whether the position of the curtain body 11 and the position of the backrest 117a overlap along the unfolding direction of the curtain body 11 according to the position of the curtain body 11 and the position of the backrest 117a.

[0148] Among them, when the curtain body 11 can be slidably adjusted relative to the body sheet metal 111, the position of the curtain body 11 can also obtain position information through detection devices such as position sensors. When the curtain body 11 cannot be slidably adjusted relative to the body sheet metal 111, the position of the curtain body 11 can be pre-set in the main control system of the vehicle 100 to facilitate comparison and analysis with the detected seat position information.

[0149] Specifically, Fig.18 As shown, if the detection result of step 2 is no, the control method further includes:

[0150] Step S23, detecting whether the curtain body 11 interferes with an object during the unfolding process; if yes, proceeding to step S3.

[0151] When the backrest 117a of the front seat 117 does not block the path of the curtain body 11 to unfold downward, the curtain body 11 meets the conditions for unfolding downward. However, sometimes some clothes and other items are placed on the backrest 117a of the front seat 117. Although the backrest 117a does not block the path of the curtain body 11 to unfold downward, these clothes and other items may block the path of the curtain body 11 to unfold downward, thereby causing interference with the curtain body 11. When interference occurs during the downward unfolding of the curtain body 11, the motor 121 that drives the curtain body 11 to unfold can sense the change in current and control the curtain body 11 to stop further unfolding, thereby preventing the curtain body 11 from generating interference wrinkles or being crushed.

[0152] In addition, when the curtain body 11 is opened, the posture of the front seat 117 can also be determined by a Hall or position sensor, and the backward sliding of the front seat 117 or the angle of the backrest 117a can be limited to avoid interference with the curtain body 11 in use during seat adjustment.

[0153] Specifically, Fig.19 As shown, if the detection result of step 2 is no, the control method further includes:

[0154] Step S24, detecting whether the distance between the backrest 117a of the front seat 117 of the vehicle 100 and the curtain body 11 along the longitudinal direction Y of the vehicle 100 is greater than a set value; if yes, proceeding to step S25.

[0155] Step S25 , controlling the curtain assembly 1 to move toward the front row of seats 117 .

[0156] The setting value may be a value between 10 and 20 mm. When the distance between the backrest 117a of the front seat 117 of the vehicle 100 and the screen body 11 along the longitudinal direction Y of the vehicle 100 is greater than 10 to 20 mm, the screen assembly 1 can have a certain adjustment space in the direction of the front seat 117, so that the screen assembly 1 can be further away from the rear passengers, thereby improving the viewing experience. When the distance between the backrest 117a of the front seat 117 of the vehicle 100 and the screen body 11 along the longitudinal direction Y of the vehicle 100 is less than 10 to 20 mm, the viewing effect is not significantly improved after the screen assembly 1 is adjusted forward, so no adjustment is required.

[0157] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
