Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to holographic display devices, holographic display systems, and vehicles. Background Technology
[0002] With the rapid development of the automotive industry, the application of holographic display technology in vehicles has become a major highlight in improving the comfort of drivers and passengers. It uses special optical principles to project images to specific positions in the air through a reflective device. However, holographic display devices occupy a large amount of space. Due to the limited space inside the vehicle, installing holographic display devices in the vehicle will reduce the passenger's experience and comfort during the ride, reduce the range of movement of drivers and passengers, and affect the sense of openness of the interior space. Summary of the Invention
[0003] The purpose of this application is to provide a floating display device, a floating display system, and a vehicle, in order to solve the technical problem in the related art that the installation of a floating display device in a limited space would affect the sense of spatial transparency.
[0004] To achieve the above objectives, this application adopts the following technical solution:
[0005] In a first aspect, this application provides a floating display device, which includes an image generating structure, an optical component, and a driving structure. The image generating structure is adapted to generate a display image, the optical component is disposed on the display side of the image generating structure for projecting the display image, and the driving structure is adapted to drive the optical component to move relative to the image generating structure so that the optical component switches between a retracted state and an unfolded state. When the optical component is in the unfolded state, it is adapted to project the display image onto a target position to form a floating image.
[0006] Under the action of the driving structure in this application, the optical components can switch between a retracted state and an unfolded state. By switching states, the occupancy of limited space can be reduced, thus solving the problem of affecting the sense of spatial transparency.
[0007] Specifically, when the floating display function is not needed, the optical components can be retracted. In this state, the optical components do not occupy installation space, maintaining the original sense of openness and transparency of the installation space. For example, during daily driving, if there is no need to view the display content, retracting the optical components will not obstruct the passenger's view or visually divide the interior space, just as if the display device does not exist, maintaining the original visual effect and spatial transparency of the limited interior space.
[0008] When a floating display is needed, the driving structure drives the optical components to unfold. In the unfolded state, the optical components are used to image the displayed image to form a floating image. Its function does not require a lot of additional space support, and it will not continuously occupy space like traditional fixed display devices, thus affecting the sense of transparency.
[0009] In some embodiments, the driving structure is adapted to drive the optical component to rotate relative to the image generating structure, so that the optical component switches between a retracted state and an unfolded state.
[0010] In some embodiments, an object distance is formed between the optical component and the display window of the image generation structure, and the optical component is adapted to satisfy the image distance to object distance ratio of the floating image P' at the target position as 1:1.

An clearance hole is disposed on the support.
[0017] In some embodiments, the rotational speed of the optical component driven by the driving structure from the retracted state to the unfolded state is a first speed, and the rotational speed of the interactive sensor driven by the driving structure from the retracted state to the unfolded state is a second speed, which is twice the first speed.
[0018] In some embodiments, when the driving structure drives the optical component from a retracted state to an unfolded state, the optical component rotates at a first angle, and when the driving structure drives the interactive sensor from a retracted state to an unfolded state, the interactive sensor rotates at a second angle, which is twice the first angle.
[0019] In some embodiments, the driving structure includes a driving member, a first active member and a second active member, both of which are connected to the output end of the driving member; and a first driven member and a second driven member, wherein the first driven member is drive-connected to the first active member, an optical component is connected to the first driven member, the second driven member is drive-connected to the second active member, and an interactive sensor is connected to the second driven member.
[0020] In some embodiments, the driving member includes a driving shaft, a first active member and a second active member are sequentially sleeved on the driving shaft, and the driving shaft is adapted to drive the first active member and the second active member to rotate synchronously.
[0021] In some embodiments, the first driving element is one of a worm gear and a worm, and the first driven element is the other of a worm gear and a worm; and / or,
[0022] The second driving member is one of the worm gear and the worm, and the second driven member is the other of the worm gear and the worm.
[0023] In some embodiments, the first driving element includes a first worm gear, and the second driving element includes a second worm gear, wherein the number of teeth of the first worm gear is twice the number of teeth of the second worm gear.
[0024] In some embodiments, the bracket includes an opposing connecting end and a cantilever end, and the driving structure is adapted to drive the cantilever end to rotate about the connecting end so that the optical component switches between a retracted state and an unfolded state.
[0025] In some embodiments, when the optical component is in the deployed state, the floating image formed by imaging the displayed image is located on the side of the optical component opposite to the image generation structure.

[0027] In some embodiments, the optical components cover the image generation structure when in a retracted state.
[0028] In some embodiments, the optical components are transparent.

[0031] In some embodiments, a connector and a light shield are also included. The connector is located on the side of the image generating structure opposite to the connection end of the optical component along a direction parallel to the display surface of the image generating structure. When the optical component is in the unfolded state, the light shield is connected between the connector and the cantilever end of the optical component.
[0032] In some embodiments, the connector is provided with a storage component, and when the optical components are in a stored state, at least part of the light-shielding component is stored in the storage component.

[0034] In some embodiments, the connector is further provided with an elastic element, which is connected between the storage shaft and the connector. When the optical component switches from the storage state to the unfolded state, the light-shielding component is disengaged from the storage shaft, and the elastic element accumulates elastic force. When the optical component switches from the unfolded state to the storage state, the elastic force accumulated by the elastic element causes the light-shielding component to gradually roll around the storage shaft.

[0036] In some embodiments, the connector is provided with a positioning groove, and a locking structure is connected to the optical component.

[0037] In some embodiments, the driving structure is connected to the locking structure, and the optical component is connected to the driving structure. The locking structure drives the optical component and the driving structure to move together toward or away from the positioning slot, so that the cantilever end of the optical component is accommodated or disengaged from the positioning slot.
[0038] In a second aspect, this application provides a vehicle that includes the aforementioned levitation display system.

[0042] It should be noted that the technical effects of the second implementation method can be found in the technical effects of the corresponding implementation method in the first aspect, and will not be repeated here. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0067] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components.

[0069] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0070] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0071] With the rapid development of the vehicle industry, the installation of multiple screens and large screens inside vehicles has become an important trend, thereby improving the comfort of drivers and passengers. In some models, displays are installed in the rear passenger area to play various multimedia content, such as videos and music.
[0072] The existing display screens in the vehicle 100, whether suspended inside the vehicle or installed on the seats, require a large amount of interior space and affect the interior layout of the vehicle 100.
[0073] To solve this problem, see Figure 1 This application provides a vehicle 100, which includes a floating display device. The floating display device can project the multimedia content to be displayed into the air. When the driver and passengers do not need to display the content, they only need to turn off the floating display device, and the projected image will disappear. The driver and passengers can still move around in the space where the image is projected. Unlike traditional display screens, the display will not occupy the space inside the vehicle after it is turned off.
[0074] Furthermore, the vehicle 100 in this application includes a canopy, and the floating display device is disposed on the canopy.
[0075] Understandably, since the floating display device is located on the skylight, when setting its installation position, it is only necessary to ensure that the projected image can be displayed in front of the driver and passengers when the floating display device is turned on. In this way, the installation of the floating display device will not occupy the visible space inside the vehicle, thus improving the user experience for the driver and passengers.
[0076] For example, see Figure 1 The sunroof is the sunroof 101 of vehicle 100.
[0077] Another example is that the canopy is the side window 102 of the vehicle 100.
[0078] For ease of understanding, this application uses a panoramic sunroof 101 of a vehicle 100 as an example.
[0079] For example, the canopy is a light-transmitting element, and the canopy includes a first dimming element for adjusting the visible light transmittance of the canopy.
[0080] When the floating display device is in operation, the first dimming element can adjust the visible light transmittance of the canopy to optimize the display background.
[0081] In bright light conditions, the transmittance of the canopy should be appropriately reduced to prevent excessive light from reflecting into passengers' eyes and reducing glare. In darker environments, the transmittance can be increased so that passengers can clearly see the floating display content without feeling visually oppressed.
[0082] Furthermore, in this application, see [link to relevant documentation]. Figure 1 The vehicle 100 also includes a side window 102, which includes a second dimming element for adjusting the visible light transmittance of the side window 102.
[0083] Correspondingly, when the floating display device is in operation, the second dimming element can adjust the visible light transmittance of the side window 102 according to the brightness and importance of the displayed content.
[0084] For example, when displaying navigation information in bright daylight, if the light transmittance of the side window 102 is too high, it will cause excessive light inside the vehicle, reducing the contrast of the floating navigation image and making it difficult to see. In this case, the light transmittance of the side window 102 can be appropriately reduced by the second dimming device to reduce interference from strong external light and make the floating navigation information clearer and more prominent.
[0085] For some floating display content that requires privacy protection, such as when passengers in the vehicle are viewing private documents or conducting video conferences, the first and second dimming components can reduce the light transmittance of the side window 102, making it difficult for outsiders to see the content of the floating display inside the vehicle.
[0086] At the same time, the lower light transmittance of the side windows 102 can help passengers focus more on the content of the floating display and reduce visual interference from external scenery.
[0087] In some embodiments, see Figure 1 and combined Figure 2 The floating display device in this application includes an image generation structure 200, which is adapted to generate a display image P.
[0088] For example, see Figure 2 The image generation structure 200 (not shown in the figure) includes a display window 201, which generates a display image P.
[0089] In some embodiments, see Figure 1 The floating display device in this application includes an optical component 300, which is disposed on the display side of the image generation structure 200 for projecting and displaying images.
[0090] For example, the optical component 300 in this application utilizes reflective imaging technology, that is, the optical component 300 is adapted to reflect the image of the display window 201 to form a floating image P'.
[0091] In some embodiments, an object distance is formed between the optical component 300 and the display window 201 of the image generation structure 200, and the optical component 300 is adapted to satisfy the image distance to object distance ratio of the floating image P' at the target position as 1:1.
[0092] See Figure 2 Object distance refers to the distance between the display window 201 of the image generation structure 200 and the optical component 300. Figure 2 L1 is used to represent this distance. It should be noted that the distance L1 from the image point of each display window 201 to the corresponding reflection point of the optical component 300 (the imaging method of this application takes reflection imaging as an example) can be different.
[0093] The distance refers to the distance between the optical component 300 and the floating image P' formed by the target position. Figure 2 L2 is used to represent this. It should be noted that the distance L2 from the floating image P' formed by each target position to the reflection point corresponding to the optical component 300 (the imaging method of this application takes reflection imaging as an example) can be different.
[0094] The optical component 300 forms a floating image P' by reflecting light from the display window 201. When light rays emerge from the display window 201 and travel a certain optical path to reach the optical component 300, the optical component 300 reflects these rays according to the law of reflection (the angle of reflection equals the angle of incidence). Since the object distance and image distance ratio between the optical component 300 and the display window 201 is 1:1, the light rays can converge at a suitable position after reflection, thereby forming a clear floating image P'.
[0095] When the levitation image P' is presented at a 1:1 object-to-image distance ratio, it creates a more realistic visual experience. The image appears to genuinely float within the car's interior, blending seamlessly with the surrounding environment and enhancing the sense of depth. Because the image-to-object distance ratio is appropriate, users don't need to excessively adjust their focus when viewing the levitation image P', just like observing a real object placed at a suitable distance. This reduces eye strain and provides a comfortable viewing experience.
[0096] In some embodiments, see Figure 8 The optical component 300 includes at least one first reflector 3031 and at least one second reflector 3032 arranged perpendicularly to each other, with the edge of the first reflector 3031 perpendicular to the edge of the second reflector 3032.
[0097] Furthermore, the optical component 300 includes a plurality of first reflectors 3031 and a plurality of second reflectors 3032, wherein the plurality of first reflectors 3031 are arranged in parallel intervals, and the plurality of second reflectors 3032 are arranged in parallel intervals.
[0098] The first reflector 3031 is mainly responsible for controlling the reflection path of light in one dimension (such as the horizontal direction). Through multiple reflections, it adjusts and converges the light in this direction as appropriate.
[0099] When light reaches the second reflector 3032, because it is perpendicular to the first reflector 3031, the second reflector 3032 reflects and converges the light in another dimension (such as the vertical direction). Through reflection and convergence in these two dimensions, the light can be precisely guided to a specific position in space, thereby forming a floating image P'.
[0100] The aforementioned optical component 300 occupies a significant portion of the limited space. It makes the already cramped interior space even more confined, potentially restricting passengers' movement and significantly reducing ride comfort.
[0101] Moreover, this space occupation also has a significant impact on the interior layout of the vehicle 100. It may disrupt the original design aesthetics and functional rationality, such as affecting the planning of storage space, the layout of the in-vehicle ventilation system, and may even interfere with the setting of in-vehicle safety facilities, thereby posing a potential threat to the overall user experience and safety of the vehicle 100.
[0102] In some embodiments, see Figure 3 , Figure 4 as well as Figure 5 The floating display device in this application includes a driving structure 400, which is adapted to drive the optical component 300 to move relative to the image generating structure 200 so that the optical component 300 switches between a retracted state and an unfolded state. When the optical component 300 is in the unfolded state, it is adapted to project a display image P onto a target position to form a floating image P'.
[0103] When the floating display function is not needed, the optical component 300 is in a retracted state. At this time, the optical component 300 is properly placed in a specific space, namely, the sunroof 101 of the vehicle 100.
[0104] When retracted, the optical component 300 does not occupy the passenger's living space or affect the visual effect inside the vehicle, maintaining the cleanliness and openness of the interior. For example, during daily driving, if the multimedia display function is not needed, the optical component 300 can be retracted without passengers noticing its presence, making the interior environment appear as if no floating display device is installed.
[0105] In some embodiments, see Figure 2 The drive structure 400 is adapted to drive the optical component 300 to rotate relative to the image generating structure 200, so that the optical component 300 switches between a retracted state and an unfolded state.
[0106] When a display is required, the drive structure 400 moves the optical component 300 to the unfolded state. During this process, the optical component 300 moves from its retracted position to the appropriate display position.
[0107] In related technologies, the limited interior space of a vehicle inherently gives people a relatively enclosed feeling. The installation of a floating display device will occupy a certain amount of space, obstructing what would otherwise be an open view.
[0108] For example, inside a small car, passengers' line of sight can freely extend from the front seats to the rear seats or windows. Installing a floating display device may visually divide the space, making passengers feel that the interior space is narrow and destroying the original sense of openness.
[0109] The retractable state of the floating display device in this application allows the optical component 300 to be stored away when not in use. In this state, the optical component 300 is properly placed in a specific space, without occupying the passenger's activity space or visually dividing the interior space, thus maintaining the original sense of openness inside the vehicle, as if the floating display device does not exist.
[0110] In addition, the floating display device in this application can be installed on any type of vehicle, whether it is a luxury car, a regular family car, or a different type of vehicle such as an SUV or MPV, which reduces production costs and complexity.
[0111] Meanwhile, the floating display device can be flexibly configured according to the specific uses of various vehicle models, providing customized display solutions for different vehicles, thereby enhancing its adaptability in various vehicle applications.
[0112] In some embodiments, when the optical component 300 is in the unfolded state, the floating image P' formed by imaging the display image P is located on the side of the optical component 300 that is opposite to the image generation structure 200.
[0113] Presenting the floating image P' on the side of the optical component 300 that is away from the image generation structure 200 can prevent the image generation structure 200 itself and related electronic components, connecting lines, etc. from interfering with the user's viewing of the floating image P'.
[0114] This setup aligns with people's typical visual habits. When observing an object, people tend to see its front rather than its back, which is obscured by other objects. By placing the levitation image P' on this side of the optical component 300, the user views it as if it were a separate object suspended in mid-air. The line of sight does not need to penetrate or bypass other parts of the optical component 300, making the viewing experience more natural and comfortable, just like directly viewing a physical object floating in front of one's eyes.
[0115] Light emitted from the image generation structure 200, after being reflected by these optical components 300, can successfully form a floating image P' on the opposite side of the optical components 300. This arrangement simplifies the design complexity of the optical system, reduces light loss and distortion during propagation, and improves image quality.
[0116] In some embodiments, see Figure 2When the optical component 300 is in the deployed state, the angle between the image generation structure 200 and the optical component 300 is equal to the angle between the optical component 300 and the floating image P'.
[0117] Within the limited space of a vehicle, this equal-angle arrangement helps to rationally position the floating display device. It allows for a relatively compact and stable spatial layout between the image generation structure 200, the optical components 300, and the floating image P'.
[0118] For users, an equal angle setting allows the floating image P' to appear more naturally. When viewing the floating image P', this angular relationship makes the image appear as if it is "floating" in a visually logical spatial location, rather than appearing at a strange angle that does not conform to visual habits.
[0119] For example, when the optical component 300 is in the unfolded state, the angle between the image generation structure 200 and the optical component 300 is greater than 0 degrees and less than or equal to 45 degrees.
[0120] It is understood that the angle between the image generation structure 200 and the optical component 300 can be 10 degrees, 30 degrees, or 45 degrees, and this application does not limit it.
[0121] It can also be understood that when the optical component 300 is in the unfolded state, the angle between the image generation structure 200 and the optical component 300 is equal to 0 degrees, which can be represented as the moment when the floating display device is started or the moment when the floating display device is turned off in this application.
[0122] In some embodiments, the optical component 300 covers the image generation structure 200 when it is in a retracted state.
[0123] Specifically, along the height direction of the vehicle, the optical component 300 is arranged to overlap with the image generation structure 200.
[0124] For example, in this application, "covering" means that when the optical component 300 is in its stored state, along the height direction of the vehicle, the optical component 300 partially or completely obscures the image generation structure 200 when the driver looks towards the image generation structure 200.
[0125] When the optical component 300 is in its retracted state and covers the image generation structure 200, it provides physical protection for the image generation structure 200. During vehicle 100 operation, various situations may occur, such as dust or foreign objects entering the vehicle, or passengers accidentally touching the equipment. The covering of the optical component 300 can prevent dust, small particles, and other impurities from falling onto the image generation structure 200, preventing damage to the delicate electronic components (such as the display screen and optical components) within the image generation structure 200. It's like putting a protective layer on these components, extending their lifespan.
[0126] In its retracted state, the optical component 300 covers the image generation structure 200, making the entire floating display device look cleaner. There are no scattered, obtrusive equipment components inside the vehicle; hiding the image generation structure 200 makes the interior space visually simpler and more streamlined. For example, in vehicles where the interior design emphasizes overall harmony, this concealed design blends better into the interior environment, preventing the exposed equipment from detracting from the aesthetics.
[0127] In some embodiments, the optical component 300 is a transparent structure.
[0128] When the optical component 300 is a transparent structure, it will not create significant visual obstruction within the vehicle interior. Whether in its retracted or unfolded state, passengers and the driver can see objects behind it through the optical component 300.
[0129] The transparent optical component 300 makes the interior space appear more spacious. In the limited interior space, this transparency prevents passengers from feeling that the space is divided or cramped. Even though the optical component 300 occupies some space, its transparency makes it seem as if it doesn't exist, allowing the interior space to appear as a continuous whole and enhancing the passenger experience.
[0130] In some embodiments, see Figure 2 This application also includes an interactive sensor 700, which is adapted to sense interactive commands for controlling the image generation structure 200.
[0131] The interactive sensor 700 allows users to interact with the floating display device in a more natural and intuitive way, enabling them to customize interaction commands according to their habits and preferences. For example, some users may be accustomed to using specific gestures to switch displayed content, adjust image size, or brightness. This personalized setting can meet the needs of different users, allowing each user to find the most suitable operating method, thereby improving user satisfaction and the overall user experience of the floating display device.
[0132] Furthermore, the interactive sensor 700 can facilitate the integration of the floating display device with other systems of the vehicle 100. For example, it can be integrated with the vehicle 100's safety system, triggering the vehicle 100's emergency braking system or issuing an alarm when a dangerous situation is detected (such as a sudden obstacle appearing in front of the vehicle 100) by sensing the user's emergency gesture command (such as a rapid hand wave). Alternatively, it can be integrated with the vehicle 100's intelligent cockpit system, adjusting seat position, air conditioning temperature, etc., based on user interaction commands, enabling collaborative operation of the vehicle 100's systems and enhancing the overall intelligence level of the vehicle 100.
[0133] For example, the interactive sensor 700 includes an infrared transmitter and an infrared receiver.
[0134] The infrared receiver transmits the received change signals to the signal processing unit. The signal processing unit analyzes these signal changes according to a pre-set algorithm. For example, when it detects that the infrared light is continuously blocked and restored a certain number of times (which may correspond to a gesture), it converts this into a corresponding interactive command, thereby controlling the image generation structure 200.
[0135] The interaction method consisting of an infrared transmitter and receiver is a contactless interaction, which is very practical in the vehicle environment. For example, in situations where the vehicle is frequently used, the hands of drivers and passengers may become contaminated from contact with various objects. Contactless interaction avoids soiling the interactive device, keeps the device clean, and also reduces the risk of bacterial transmission. This contactless interaction method conforms to people's natural movement habits. Users can operate the device through simple gestures, such as waving or tapping in the air, just as naturally as interacting with their surroundings in daily life.
[0136] In some embodiments, the drive structure 400 is also adapted to drive the interactive sensor 700 to switch between a retracted state and an unfolded state.
[0137] During vehicle 100's operation, the interactive sensor 700 may be damaged due to collisions, scratches, or other unexpected events. When in its stored state, it can be properly protected from interference by these external factors.
[0138] Furthermore, when the interactive sensor 700 is retracted, the interior of the vehicle 100 looks cleaner and more unified. The unsightly presence of the sensor does not detract from the overall aesthetics and design style of the interior.
[0139] In some embodiments, the driving structure 400 is adapted to drive the optical component 300 and the interactive sensor 700 to switch synchronously from a retracted state to an unfolded state, and to drive the optical component 300 and the interactive sensor 700 to switch synchronously from an unfolded state to a retracted state.
[0140] When the drive structure 400 synchronously switches the states of the optical component 300 and the interactive sensor 700, the user will experience consistent operation when using the floating display device.
[0141] Understandably, when a user activates the floating display function, the optical component 300 unfolds to display the floating image P', while the interactive sensor 700 also unfolds and is ready to receive interactive commands, just like opening a complete display interaction system. This synchronous operation meets the user's intuitive expectations for turning the device on and off, reduces the trouble of waiting and operating different components separately, and improves the smoothness of the user experience.
[0142] Furthermore, when the interactive sensor 700 is in the unfolded state, the sensing surface of the interactive sensor 700 is set to be coplanar with the floating image P' formed by the optical component 300.
[0143] The sensing surface and the floating image P' are on the same plane, which reduces the sensing error caused by depth differences or angle deviations, and allows the interactive commands to be more accurately mapped to the image content that the user wants to operate.
[0144] In some embodiments, the optical component 300 is provided with a clearance hole 3041, and when the interactive sensor 700 is in a retracted state, the interactive sensor 700 is housed within the clearance hole 3041.
[0145] This allows for a very compact internal space layout. It also enhances the stability of the entire floating display device. When the interactive sensor 700 is properly housed within the clearance hole 3041, the relative positions of the various parts of the device are more stable during vehicle 100 operation. Compared to having the interactive sensor 700 independently placed externally, this reduces potential interference between components or loose connections caused by sensor movement or displacement, thus helping to maintain the normal operation of the device.
[0146] In some embodiments, see Figure 5 And continue to combine Figure 1 , Figure 2 The optical component 300 includes an imaging element 303 and a support 304. The imaging element 303 is disposed on the support 304. The support 304 includes a connecting end 302 and a cantilever end 301. The driving structure 400 is adapted to drive the cantilever end 301 to rotate around the connecting end 302 so that the optical component 300 switches between a retracted state and an unfolded state.
[0147] The imaging element 303 is mounted on the bracket 304. The drive structure 400 is connected to the bracket 304 so as to drive the bracket 304 and drive the imaging element 303 to rotate, so that the optical component 300 can switch between a retracted state and an unfolded state. The clearance hole 3041 is mounted on the bracket 304.
[0148] When the optical component 300 is in the retracted state, the drive structure 400 drives the cantilever end 301 to rotate around the connecting end 302, which can cleverly store the optical component 300 in a corner of the vehicle 100 interior or close to other components. This rotating storage method can make more effective use of irregular spaces inside the vehicle compared to translational storage.
[0149] When the floating display function is needed, the optical component 300 is deployed by driving the cantilever end 301 to rotate around the connecting end 302. The deployment path can be flexibly designed according to the actual space layout and usage requirements of the vehicle.
[0150] The mechanical structure that drives the cantilever end 301 to rotate around the connecting end 302 is relatively simple. It may only require a simple rotating shaft and a corresponding drive motor or transmission mechanism. Compared with some complex translation-telescopic drive structures 400, this rotating structure has fewer parts, reducing the probability of mechanical failure.
[0151] Furthermore, this rotating state-switching method is more intuitive for users. Passengers or drivers can clearly see the unfolding and retraction process of the optical component 300, as naturally as opening and closing a cover with a hinge.
[0152] This visual operation process allows users to better understand the device's working status and increases their sense of security when using it. For example, when a user presses the on or off button on the display device, they can see the optical component 300 rotating around the connection end 302 to unfold or retract, allowing them to intuitively confirm whether the device is working properly.
[0153] The imaging element 303 is mounted on the bracket 304, forming a relatively independent optical component 300 module. This modular design facilitates production and quality control during manufacturing. The factory can manufacture the bracket 304 and the imaging element 303 separately and then assemble them, improving production efficiency. Furthermore, when installing the levitation display device, this optical component 300 module can be installed as a whole, reducing installation steps and complexity.
[0154] The clearance hole 3041 is disposed on the bracket 304, which can better integrate with the layout of the imaging element 303 and the drive structure 400. The structure of the bracket 304 can be designed as needed so that the position and size of the clearance hole 3041 are adapted to the shape and storage method of the interactive sensor 700.
[0155] In some embodiments, the rotational speed of the optical component 300 from the retracted state to the unfolded state driven by the drive structure 400 is a first speed, and the rotational speed of the interactive sensor 700 from the retracted state to the unfolded state driven by the drive structure 400 is a second speed.
[0156] Furthermore, in order to ensure that the sensing light emitted by the interactive sensor 700 is collinear with the floating image P', the second speed is twice the first speed.
[0157] It should be noted that the driving structure 400 is suitable for driving the optical component 300 and the interactive sensor 700 to rotate simultaneously around the same axis. Correspondingly, the first speed and the second speed in this application refer to the angular velocities of the optical component 300 and the interactive sensor 700 during the rotation process.
[0158] Correspondingly, based on the object distance and phase distance being 1:1, in order to ensure that the interactive sensor 700 is timely in sensing, that is, that the light emitted by the interactive sensor 700 can enter the plane where the floating image P' is located, when the driving structure 400 drives the optical component 300 from the retracted state to the unfolded state, the optical component 300 rotates at a first angle, and when the driving structure 400 drives the interactive sensor 700 from the retracted state to the unfolded state, the interactive sensor 700 rotates at a second angle, wherein the second angle is twice the first angle.
[0159] By setting the rotation speed of the interaction sensor 700 to twice that of the optical component 300, it can be ensured that the interaction sensor 700 is accurately collinear with the floating image P' during deployment. This collinearity is crucial for accurately sensing interactive actions directed at the floating image P'. For example, in the use of the interaction sensor 700, the collinearity of the sensing light with the floating image P' ensures that the sensor accurately captures gestures or other interactive actions occurring on the plane of the floating image P', thereby improving the accuracy of interactive commands.
[0160] Different rotation speed settings can also rationally allocate the power resources of the drive structure 400 according to the actual needs of the optical component 300 and the interactive sensor 700. Since the interactive sensor 700 needs to reach the working position faster to achieve collinearity between the sensed light and the floating image P', allocating it a higher rotation speed can ensure that this crucial setup is completed quickly without wasting too much energy. At the same time, the relatively slow deployment of the optical component 300 can also ensure stability and accuracy when forming the floating image P'.
[0161] In some embodiments, the drive structure 400 includes a drive member 401, a first active member 402, and a second active member 404, both of which are connected to the output terminal of the drive member 401.
[0162] The drive structure 400 includes a first follower 403 and a second follower 405. The first follower 403 is drivenly connected to the first driving member 402. The optical component 300 is connected to the first follower 403. The second follower 404 is drivenly connected to the second driving member 404. The interactive sensor 700 is connected to the second follower 404.
[0163] The driving component 401 serves as a power source, and its output end is connected to the first driving component 402 and the second driving component 404, thereby realizing power distribution. The first driving component 402 and the second driving component 404 transmit power to the first driven component 403 and the second driven component 405 respectively through transmission connections.
[0164] Specifically, the driving component 401 includes a driving shaft, and the first driving component 402 and the second driving component 404 are sequentially sleeved on the driving shaft, and the driving shaft is adapted to drive the first driving component 402 and the second driving component 404 to rotate synchronously.
[0165] For example, there can be one or two driving elements 401. The first active element 402 and the second active element 404 can be driven by the same driving element 401 or they can be driven separately.
[0166] In some embodiments, see Figure 7 The first driving member 402 is one of the worm gear and the worm, and the first driven member 403 is the other of the worm gear and the worm.
[0167] The second driving member 404 is one of the worm gear and the worm, and the second driven member 404 is the other of the worm gear and the worm.
[0168] Correspondingly, the first driving element 402 includes a first worm gear, and the second driving element 404 includes a second worm gear, wherein the number of teeth of the first worm gear is twice the number of teeth of the second worm gear.
[0169] Worm gear drives possess self-locking characteristics. In the holographic display device, when the first driving member 402 and the first driven member 403 (or the second driving member 404 and the second driven member 405) employ worm gear drives, this self-locking property prevents the optical component 300 (or the interactive sensor 700) from reversing when subjected to external forces. For example, if the vehicle 100 encounters bumps or vibrations while traveling, or if a passenger accidentally touches the device, the optical component 300 and the interactive sensor 700 can remain in their current positions and will not unexpectedly change their state due to these external forces, thus improving the safety and stability of the system.
[0170] In some embodiments, see Figure 6 and combined Figure 2 as well as Figure 1 This application also includes a connector 800, which is located on the side of the image generating structure 200 opposite to the connector end 302 of the optical component 300, along a direction parallel to the display surface of the image generating structure 200.
[0171] This application also includes a light-shielding member 600, which is connected between the connecting seat 800 and the cantilever end 301 of the optical component 300 when the optical component 300 is in the unfolded state.
[0172] The light-shielding member 600 is connected between the connector 800 and the cantilever end 301 of the optical component 300, and its position and orientation are designed according to the light propagation path. It can block stray light that may interfere with the display of the levitating image P', so that the light is mainly concentrated in the effective area of the optical component 300 used to form the levitating image P', similar to using a light-shielding plate to control the light path in optical experiments.
[0173] The connector 800 is located on the side of the image generating structure 200 opposite to the connector end 302 of the optical component 300, in a direction parallel to the display surface of the image generating structure 200. This position is chosen so that after the optical component 300 is unfolded, it can cooperate with the cantilever end 301 of the optical component 300 to form a suitable spatial structure for installing the light shield 600.
[0174] The light-shielding element 600 can effectively cover the area where stray light may occur between the image generation structure 200 and the optical component 300 in this position, without obstructing the normal optical path of the floating image P'.
[0175] By blocking stray light, the light-shielding component 600 can significantly improve the contrast of the floating image P'. Without the light-shielding component 600, stray light can make the image appear blurry and dim, especially when displaying content that requires high contrast (such as navigation instructions at night, vehicle status information, etc.). The light-shielding component 600 reduces the interference of background light, making the bright areas of the image brighter and the dark areas darker, thus making the details of the image clearer and improving the user's ability to recognize the content of the floating image P'.
[0176] In some embodiments, the connector 800 is provided with a storage member 801, and when the optical component 300 is in a stored state, at least part of the light-shielding member 600 is stored in the storage member 801.
[0177] That is, the light-shielding component 600 can be completely stored in the storage component 801, or it can be partially stored in the storage component 801.
[0178] When the sunshade 600 is not needed (i.e., the optical component 300 is in its retracted state), storing it away saves interior space. This space optimization is especially important for vehicles with limited interior space. The retracted sunshade 600 does not take up extra space, making the interior environment cleaner and more spacious, and preventing any inconvenience to passengers due to its presence.
[0179] Furthermore, the light-shielding component 600 is a flexible structure, and the storage component 801 is a storage shaft. When the optical component 300 is in the storage state, the light-shielding component 600 is wound around the storage shaft.
[0180] In some embodiments, the connector 800 is further provided with an elastic element, which is connected between the storage shaft and the connector 800. When the optical component 300 switches from the storage state to the unfolded state, the light-shielding member 600 is disengaged from the storage shaft, and the elastic element accumulates elastic force. When the optical component 300 switches from the unfolded state to the storage state, the elastic force accumulated by the elastic element causes the light-shielding member 600 to gradually roll around the storage shaft.
[0181] For example, the elastic element is a torsion spring.
[0182] In some embodiments, the floating display device is applied to the vehicle 100, and the connecting seat 800 is located on the front side of the image generation structure 200 along the front-rear direction of the vehicle 100.
[0183] Furthermore, the floating display device is located between the front seat 103 and the rear seat 104.
[0184] Because the floating display device is positioned at a suitable line of sight for passengers, they do not need to twist their bodies excessively or look up or down while viewing it, thus reducing the strain on their eyes and effectively minimizing visual fatigue.
[0185] The primary line of sight for occupants is forward, a layout that allows the holographic image P' to be better presented within the field of vision of both passengers and the driver, facilitating viewing. Simultaneously, the relatively spacious area between the front and rear seats provides ample installation space for the holographic display device without excessively encroaching on passenger comfort.
[0186] In some embodiments, see Figure 9 as well as Figure 10 This application also includes a locking structure, which is used to lock or unlock the optical component 300 (not shown in the figure) when the optical component 300 is in the retracted position.
[0187] The locking structure typically works in conjunction with a position detection system for the optical component 300. When the system detects that the optical component 300 has reached its storage position, it sends a signal to the locking structure, triggering the locking action. This position sensing can be achieved using sensors (such as limit switches, Hall effect sensors, etc.) to ensure that the locking structure engages at the correct time, thereby guaranteeing the stability of the optical component 300 in its stored state.
[0188] In some embodiments, see Figure 10 The connector 800 is provided with a positioning groove 802, and a locking structure is connected to the optical component 300. The locking structure is used to drive the optical component 300 to move towards or away from the positioning groove 802, so that the cantilever end 301 of the optical component 300 is accommodated or disengaged from the positioning groove 802, thereby locking or unlocking the optical component 300.
[0189] The positioning groove 802 and the cantilever end 301 work together to achieve very precise locking. The shape and size of the positioning groove 802 can be designed according to the cantilever end 301 of the optical component 300 to ensure that the cantilever end 301 can be accurately positioned after entering the positioning groove 802, thus preventing the optical component 300 from shaking or shifting when stored.
[0190] In some embodiments, the drive structure 400 is connected to the locking structure, and the optical component 300 is connected to the drive structure 400. The locking structure drives the optical component 300 and the drive structure 400 to move together toward or away from the positioning groove 802, so that the cantilever end 301 of the optical component 300 is accommodated or disengaged from the positioning groove 802.
[0191] The drive structure 400 is connected to the locking structure, and the optical component 300 is connected to the drive structure 400, forming an organic whole. When the locking structure receives a drive signal (which can be electric, hydraulic, or other drive methods), it transmits power to the drive structure 400. Since the optical component 300 is connected to the drive structure 400, all three will move together towards or away from the positioning groove 802. This coordinated movement is based on the transmission of force and the tightness of the mechanical connection, like a linked mechanical device, where each part moves synchronously in a predetermined manner to achieve the engagement or disengagement of the cantilever end 301 of the optical component 300 with the positioning groove 802.
[0192] This connection method tightly integrates the locking structure, drive structure 400, and optical component 300 into a relatively compact system. Compared to setting the locking and drive functions independently, it reduces the connection links and space occupation between components, allowing the entire floating display device to be more rationally arranged in the limited space inside the vehicle.
[0193] Correspondingly, in this application, the first dimming element is used to adjust the visible light transmittance of the canopy. When the optical component 300 is in the unfolded state, the first dimming element is used to adjust the visible light transmittance of the canopy to a first preset value. When the visible light transmittance of the canopy is at the first preset value, the canopy is in a dark state.
[0194] Furthermore, the second dimming element is used to adjust the visible light transmittance of the side window 102. When the optical component 300 is in the unfolded state, the second dimming element is used to adjust the visible light transmittance of the side window 102 to a second preset value. When the visible light transmittance of the side window 102 is at the second preset value, the side window 102 is in a dark state.
[0195] With the optical component 300 deployed, it is necessary to control the interference of ambient light in order to better display the floating image P'. By coordinating the first and second dimming components, the entire interior space can be adjusted to a dark state, which can reduce the light entering from behind the sunroof and from outside the vehicle through the side windows 102.
[0196] It should be noted that there may be only one of the first dimming element and the second dimming element, or there may be both of them. This application does not limit this.
[0197] When the interior of the vehicle is dark, the interference of ambient light on the levitation image P' is significantly reduced. This improves the contrast between the bright and dark areas of the levitation image P', making the image details clearer and more discernible.
[0198] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
