Specific embodiments

[0029] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for explaining the present invention and not for limiting the protection scope of the present invention.

[0030] In one embodiment, the present invention provides an in-vehicle projection system. Refer to Figure 1 As shown, the projection system includes a detection element 1, a controller 2, a projection carrier 3, and a projection device 4.

[0031] The detection element 1 is used to detect the position information of in-vehicle occupants and send the detection result to the controller.

[0032] The controller 2 is used to receive the detection result of the detection element 1 and determine the target projection area information based on the detection result.

[0033] The projection carrier 3 is located at the top of the vehicle interior and includes a plurality of projection areas 31.

[0034] The projection device 4 is located inside the vehicle and is used to receive the target projection area information of the controller 2 and image the image to be displayed onto the target projection area 31 of the projection carrier 3.

[0035] The projection carrier 3 of the present invention is arranged on the top of the vehicle interior and includes a plurality of projection areas 31, making full use of the relatively low-utilization space resource on the top of the vehicle interior. The arrangement of the projection carrier 3 does not occupy other activity spaces in the vehicle, such as the space around the seats, the aisle space, etc., and will not cause interference to the normal sitting and activities of the occupants, such as getting in and out of the seats, adjusting the sitting posture in the vehicle, etc., ensuring the comfort of the occupants' sitting and the convenience of activities.

[0036] The projection device 4 of the present invention is located inside the vehicle. Compared with the devices installed at some specific positions, its layout is more flexible. It can select a suitable installation position according to the specific structure and design requirements of the vehicle and is easier to install. And when the device fails and needs maintenance in the later stage, due to the flexibility of its layout, it is also convenient for the staff to perform inspections, repairs and other operations, reducing the difficulty and cost of maintenance.

[0037] The detection element 1 of the present invention is used to detect the position information of the vehicle occupants. The controller 2 generates target projection area information based on this. The projection device 4 projects the image to be displayed onto the target projection area of the projection carrier 3, which can perform projection adjustment according to the positions of different occupants, ensuring that each occupant can obtain a better viewing angle and viewing effect, avoiding the situation of inconvenient viewing or inability to view due to different positions, making the in-vehicle entertainment system more user-friendly and improving the overall quality of the entertainment experience.

[0038] As a preferred embodiment of the present invention, refer to Figure 1 As shown, the projection carrier 3 is located below the roof skylight glass or the roof panoramic glass; the projection carrier 3 can be switched between a storage state and an unfolded state; in response to the projection carrier 3 being in the unfolded state, the projection carrier 3 is used as a sunshade member.

[0039] With such a setting, the projection carrier 3 can not only be used as a medium for projection display, but also act as a sunshade member when in the unfolded state, realizing multiple functions with one object and enhancing the functionality and practicality of the device. When projection is needed, the projection carrier 3 can display images to meet the entertainment needs. When the sun is strong, the projection carrier 3 is unfolded as a sunshade member to block the direct sunlight, reduce the temperature inside the vehicle, and provide a more comfortable riding environment for the occupants, effectively avoiding the discomfort caused by sunlight irradiation, such as glare, high temperature and other problems.

[0040] The projection carrier 3 can be switched between a storage state and an unfolded state. When in the storage state, it does not occupy too much space inside the vehicle, ensuring the simplicity and openness of the top space inside the vehicle, and not affecting the headroom of the occupants and the original lighting and other functions of the sunroof. When the projection and / or sunshade functions are needed, it can be unfolded for use. This flexible switching method makes the utilization of the vehicle interior space more reasonable and adapts to different usage scenarios and requirements.

[0041] As a sunshade component, the projection carrier 3 can reduce the direct sunlight on the vehicle interior, reduce the load of the vehicle air conditioner, thereby achieving an energy-saving effect. At the same time, effectively blocking sunlight can also reduce the aging and fading of the vehicle interior due to long-term exposure to the sun, and extend the service life of the interior. In addition, the reduction of the vehicle interior temperature and glare greatly improves the riding comfort of the occupants. Whether it is a long-distance trip or daily commuting, it can provide a better experience for the occupants.

[0042] The projection carrier 3 is arranged below the roof sunroof glass or the roof panoramic glass, combined with the existing structure of the vehicle. While realizing multiple functions, it does not damage the original overall design and structural layout of the vehicle. This setting method not only makes full use of the characteristics of the vehicle itself, but also provides convenience for the installation and use of the projection carrier 3, making the adaptability of the system to the vehicle better and making it easier to promote and apply on different vehicle models.

[0043] Furthermore, the projection carrier 3 realizes the switching between the storage state and the unfolded state through a roll-up structure, a folding structure or a telescopic structure.

[0044] Specifically, the roll-up structure includes a roll and a driving mechanism. The projection carrier 3 (such as a curtain) is wound around the rotatable roll, and the unfolding and storage of the projection carrier 3 are realized by the rotation of the roll through the driving mechanism (motor or manual drive). When driven by a motor, the rotation angle and speed of the roll can be accurately controlled by the controller 2, so as to accurately control the unfolding and storage degree of the projection carrier 3. Manual drive generally pulls the free end of the projection carrier 3 to move the projection carrier 3 to a preset position. With such a setting, the structure is relatively simple, occupies less space, and when stored, the projection carrier 3 is tightly wound around the roll and is not easily damaged. The unfolding process is relatively stable, which can ensure that the projection carrier 3 unfolds flatly, which is beneficial to obtaining a good projection effect.

[0045] When the projection carrier 3 switches between the storage state and the unfolded state through a folding structure, the projection carrier 3 is composed of a plurality of linkages and a plurality of foldable plates, and the folding and extension of the linkages or the plates are controlled by a mechanical device (such as a hydraulic rod, an electric push rod, etc.) or manual operation. For example, a parallelogram linkage mechanism is adopted. When the linkage is pushed or pulled, the projection carrier can be folded or unfolded like an accordion. With such a setting, it can be quickly unfolded and stored, and can provide relatively stable support in the unfolded state, ensuring the flatness of the projection carrier. At the same time, the folding structure is relatively strong and can withstand a certain amount of external force, making it suitable for larger-sized projection carriers.

[0046] When the projection carrier 3 switches between the storage state and the unfolded state through a telescopic structure, the projection carrier 3 adopts a telescopic material or structure, such as elastic fabric, corrugated pipe, etc., and the projection carrier 3 is controlled to expand and contract by an internal spring, a pneumatic device or an electric mechanism. When it needs to be unfolded, the projection carrier 3 is pushed to extend; when it is stored, the projection carrier 3 is pulled to contract. With such a setting, the unfolding and storage processes are relatively flexible and can adapt to different space requirements. The telescopic structure can adjust the size of the projection carrier according to the actual situation and has good versatility.

[0047] In one embodiment, as shown in Figures 2 to 5 the in-vehicle projection system of the present invention further includes a support structure, and the projection carrier 3 is supported by the support structure so that the projection area of the projection carrier 3 is a stable plane.

[0048] A stable plane is crucial for the projection effect. When the projection area of the projection carrier 3 is a stable plane, the image projected by the projection device 4 can be accurately imaged on the plane, avoiding image distortion, warping or blurring caused by the uneven surface of the projection carrier 3. As a result, the occupant can view a clear, complete and undistorted projection image, greatly enhancing the visual effect and entertainment experience of the projection. Moreover, the stable projection image allows the occupant to focus more on the projection content without worrying about the impact on the image quality. This not only improves the occupant's entertainment enjoyment in the vehicle but also makes the in-vehicle projection system more attractive and practical. For the occupant, a stable and reliable projection system can increase their satisfaction with the vehicle entertainment function and enhance the overall riding experience.

[0049] Meanwhile, since the support structure provides a stable support for the projection carrier 3, the projection carrier 3 can remain in a stable state even when encountering bumps, vibrations, etc. during vehicle driving. The position offset or jitter of the projection carrier 3 caused by shaking is reduced, enabling the in-vehicle projection system to adapt to various complex driving scenarios. Whether it is frequent starting and stopping on urban roads, smooth driving on highways, or bumpy driving on rough roads, stable projection services can be provided for passengers.

[0050] As a preferred implementation manner of this embodiment, referring to Figure 2 and Figure 3 as shown, the projection carrier 3 is a flexible curtain, and the support structure includes a plurality of first support units 5. Each first support unit 5 includes a first rod 51, a second rod 52, and a third rod 53 arranged in parallel with each other; the first rod 51 and the second rod 52 are arranged at intervals in the horizontal direction, and the third rod 53 is arranged above or below the gap between the first rod 51 and the second rod 52. The free end of the flexible projection carrier 3 extends into the gap between the first rod 51 and the third rod 53 and extends out from the gap between the second rod 52 and the third rod 53.

[0051] In this preferred implementation manner, a flexible curtain is used as the projection carrier 3, which has good flexibility and bendability. When the projection carrier 3 is stored, it can be easily wound or folded, occupying extremely small space and being conveniently stored at a specific position on the top of the vehicle interior without affecting the use of other spaces in the vehicle. Moreover, during vehicle driving, the flexible curtain can better adapt to the vibration and deformation of the vehicle and is not easily damaged due to rigid collision, increasing the durability of the projection carrier 3.

[0052] Referring to Figure 3As shown, the support structure is composed of several first support units 5. The first rod 51 and the second rod 52 of each first support unit 5 are arranged at intervals in the horizontal direction, and the third rod 53 is arranged above or below the gap between the two. This structural design provides a stable support framework for the flexible curtain. When the projection carrier 3 is unfolded, the flexible curtain is tightened through the gaps between the first rod 51 and the third rod 53, and between the second rod 52 and the third rod 53, so that the projection area can remain flat, forming a stable plane, thereby ensuring the quality of the projection image and avoiding image distortion caused by the slack or unevenness of the curtain. Moreover, this form of support structure is relatively simple to install, and the combination method of each component is clear. During the installation process, it is only necessary to pass the flexible curtain through the rod gaps of the first support unit 5 according to the specified path to complete the installation. During later maintenance, if it is necessary to replace or adjust the projection carrier 3, the curtain can also be conveniently removed from the support structure or reinstalled. At the same time, due to the modular design of the support structure (composed of several first support units), if a certain first support unit 5 has problems, only this unit needs to be replaced, reducing the maintenance cost and difficulty.

[0053] In this preferred embodiment, due to the combination method of the flexible curtain and the support structure, the projection carrier 3 can be flexibly arranged according to the specific shape and space of the vehicle interior roof. Whether it is the relatively regular space under the roof skylight glass or the panoramic roof glass, or other irregular areas of the vehicle interior roof, the projection carrier 3 can be supported and fixed by reasonably setting the first support units 5, improving the adaptability of the in-vehicle projection system to different vehicle models and interior environments.

[0054] The flexible curtain forms a flat projection area under the action of the support structure, which can better reflect the light projected by the projection device and present a clearer and more vivid projection image. Moreover, the material of the flexible curtain can be selected according to needs to optimize the visual effect of the projection. For example, a curtain material with a high reflectivity or specific diffuse reflection characteristics can be selected to meet different projection requirements.

[0055] Exemplarily, refer to Figure 2 As shown, the length direction of the first support unit 5 is the same as the vehicle width direction, and the left and right end parts of the first rod 51, the second rod 52 and the third rod 53 are respectively slidably connected to the chutes inside the left and right side beams of the roof.

[0056] The flexible curtain is fixed by the same installation method as the conventional sunshade curtain, that is, the projection carrier 3 can be manually or electrically controlled to be unfolded or retracted.

[0057] Further, the edges of the first rod 51, the second rod 52, and the third rod 53 in contact with the projection carrier 3 are smoothly transitioned. With such a setting, on the one hand, it can effectively avoid damage such as scratching and cutting of the projection carrier 3 by sharp corners, prolong the service life of the flexible projection carrier 3, and reduce the cost increase and maintenance inconvenience caused by frequent replacement of the projection carrier 3. On the other hand, during the unfolding and storage process of the projection carrier 3, the smoothly transitioned edges can make the projection carrier 3 pass through the support structure more smoothly. If the edges are not smooth, it may cause the curtain to get stuck or blocked during movement, affecting the efficiency of unfolding and storage, and even may cause distortion or damage to the curtain. While the smooth edges can reduce the frictional resistance, ensure that the projection carrier 3 can move smoothly in the support structure, and ensure the normal operation of the entire projection system.

[0058] As a preferred implementation manner of this embodiment, referring to Figure 4 as shown, the support structure includes a plurality of second support units 6. Each second support unit 6 includes a fourth rod 61 and a fifth rod 62. One end of the fourth rod 61 is rotatably connected to the vehicle body, the other end of the fourth rod 61 is rotatably connected to one end of the fifth rod 62, the other end of the fifth rod 62 is rotatably connected to the free end of the projection carrier 3, and a locking structure is provided at the connection position of the fourth rod 61 and the fifth rod 62.

[0059] Exemplarily, referring to Figure 4 as shown, one end of the fourth rod 61 is rotatably connected to the box body 32 for storing the projection carrier 3, the other end of the fourth rod 61 is rotatably connected to one end of the fifth rod 62, and the other end of the fifth rod 62 is rotatably connected to the connecting rod 33 at the free end of the projection carrier 3.

[0060] Due to the rotatability of the support structure, when it is necessary to store the projection carrier 3, the support structure can be folded by rotating the fourth rod 61 and the fifth rod 62 to reduce the occupied space. When it is necessary to unfold the projection carrier 3, the support structure can be easily unfolded and adjusted to a suitable position. The operation is simple and convenient, does not affect the normal use of other spaces in the vehicle, and at the same time improves the use efficiency of the projection system. It should be noted that although the support structure has the characteristic of being rotatable, a locking structure is provided at the connection position of the fourth rod 61 and the fifth rod 62. After adjusting the angle and position of the support structure, the fourth rod 61 and the fifth rod 62 can be firmly fixed together through the locking structure, so as to provide stable support for the projection carrier 3. Even when the vehicle encounters vibrations, bumps and other situations during driving, it can ensure that the projection carrier remains stable without shaking or displacement, ensuring the stability and quality of the projection screen.

[0061] As a preferred implementation manner of this embodiment, the support structure includes a plurality of airbags 7 arranged between the projection carrier 3 and the vehicle roof. One side of the airbag 7 close to the projection carrier 3 is flat and is used to support the projection carrier 3.

[0062] The airbag 7 can evenly distribute the pressure between the projection carrier 3 and the vehicle roof. Since one side of the airbag 7 close to the projection carrier 3 is flat, the projection carrier 3 can be supported flatly and stably. Compared with the traditional rigid support structure, the elastic characteristics of the airbag 7 can better adapt to the vibration and bump during vehicle driving, always keep the projection carrier 3 flat, avoid the projection image being deformed or blurred due to vibration, and ensure the projection quality.

[0063] By controlling the inflation amount of the airbag 7, its height and hardness can be adjusted, so as to finely adjust the position and angle of the projection carrier 3 according to actual needs. For example, when it is necessary to adjust the inclination of the projection image to meet the viewing needs of different occupants, it can be achieved by adjusting the inflation amount of the corresponding airbag 7. This flexible adjustment ability enables the in-vehicle projection system to better meet the personalized needs of different occupants and improves the user experience.

[0064] Moreover, compared with some complex mechanical support structures, the installation of the airbag 7 is relatively simple. It only needs to be arranged between the projection carrier 3 and the vehicle roof and the inflation system is connected. In terms of maintenance, the inspection and replacement of the airbag 7 are also relatively convenient. If a certain airbag 7 fails or is damaged, only this airbag 7 needs to be replaced, and there is no need to perform large-scale disassembly and repair on the entire support structure, reducing the maintenance cost and difficulty.

[0065] At the same time, the airbag 7 can be in a flat state when not inflated, occupying a small space and being convenient for storage and placement. When the projection system needs to be used, the airbag 7 is inflated to expand and support the projection carrier 3. This retractable characteristic enables the support structure to minimize the occupation of the in-vehicle space when the projection system is not in use, improving the utilization rate of the in-vehicle space and not affecting the normal activities of the occupants in the vehicle.

[0066] It should be noted that the material and color of the airbag 7 are selected and customized according to the interior style of the vehicle to better integrate it with the in-vehicle environment and not affect the overall beauty of the vehicle.

[0067] As a preferred implementation manner of the present invention, as shown in Figure 6 、 Figure 7 and Figure 8 shown, the projection device 4 is connected to the vehicle body through a position adjustment mechanism 8.

[0068] See Figure 6As shown, the position adjustment mechanism 8 includes a lifting assembly 81, a rotating assembly 82, and an angle adjustment assembly 83. The lifting assembly 81 is fixed to the vehicle body, and the power output end of the lifting assembly 81 is fixedly connected to the rotating assembly 82. The power output end of the rotating assembly 82 is fixedly connected to the angle adjustment assembly 83, and the output end of the angle adjustment assembly 83 is fixedly connected to the projection device 4.

[0069] Through the arrangement of the lifting assembly 81, the projection device 4 can be adjusted in position in the vertical direction. For example, when the seat position of the vehicle occupants is relatively high or low, the projection device 4 can be lifted to ensure that the height of the projection screen is suitable for the occupants to view, improving the adaptability of the projection device 4 in the vertical space and meeting the requirements of different occupants for the projection height.

[0070] The rotating assembly 82 is connected to the lifting assembly 81 and the angle adjustment assembly 83, enabling the projection device 4 to rotate in the horizontal direction, ensuring that the projection device 4 can cover different projection areas of the projection carrier 3, greatly expanding the usage range of the projection device 4, and providing projection services for the occupants in different seats.

[0071] The angle adjustment assembly 83 is directly connected to the projection device 4, and can finely adjust the projection angle of the projection device 4. By adjusting the angle, the projection screen can be accurately projected onto the appropriate position of the projection carrier 3, ensuring the integrity and accuracy of the projection screen, and avoiding image distortion or incomplete display caused by angle deviation.

[0072] This flexibly adjustable position adjustment mechanism 8 can adjust the position and angle of the projection device 4 according to the target projection area information generated by the controller 2 or the preferences and actual situations of the occupants, enabling users to easily find the most suitable viewing position and angle, and enjoy a more comfortable and personalized projection experience, thereby improving the satisfaction with the in-vehicle entertainment system. And since the projection device 4 can be flexibly adjusted by the position adjustment mechanism 8, when not in use, the projection device 4 can be adjusted to a suitable position, avoiding occupying too much in-vehicle space and not affecting the normal activities of the occupants in the vehicle.

[0073] The arrangement of the position adjustment mechanism 8 enables the projection device 4 to adapt to different types of vehicles. Whether it is a small car, a large bus, or other special vehicle models, the projection device 4 can be installed and used by adjusting the position adjustment mechanism 8, enhancing the compatibility and versatility of the in-vehicle projection system and expanding its application range.

[0074] Exemplarily, the lifting assembly 81 includes a first base, a first driving motor fixed on the first base, and a lifting rod drivingly connected to the output end of the first driving motor. The lifting rod can move in the up and down direction to a preset position under the drive of the first driving motor.

[0075] The rotating assembly 82 includes a second base connected to the upper end of the lifting rod of the lifting assembly 81, a second driving motor fixed on the second base, and a turntable fixedly connected to the output end of the second driving motor. The turntable makes a rotational motion under the action of the second driving motor.

[0076] The angle adjustment assembly 83 includes a third base fixed to the edge of the turntable of the rotating assembly 82, a rack fixed on the third base, a gear fixed on the projection device and meshing with the rack, and a third driving motor for driving the gear to rotate.

[0077] As a preferred embodiment of the present invention, as shown in Figures 7 to 9 the vehicle body is provided with a chamber 9 for accommodating the position adjustment mechanism 8 and the projection device 4, and a cover plate 10 opening and closingly connected to the opening position of the chamber 9; the chamber 9 is located at the upper end of the backrest of the rear row seat 30 and / or the rear of the center console 20.

[0078] The position adjustment mechanism 8 and the projection device 4 are housed in a dedicated chamber 9. When the projection system is not in use, these devices do not occupy the active space inside the vehicle, ensuring the spaciousness of the space for the rear passengers' legs, heads, etc., and improving the riding comfort. Especially for vehicles with limited space, the setting of the chamber 9 can effectively utilize the originally idle space inside the vehicle, such as the space inside the rear seat backrest or the rear of the center console 20, and avoid the impact of the exposed devices on the interior space layout of the vehicle. Moreover, the chamber 9 provides a relatively enclosed environment for the position adjustment mechanism 8 and the projection device 4, which can effectively prevent dust and debris from entering the interior of the devices (i.e., the position adjustment mechanism 8 and the projection device 4), reducing the risk of device damage due to external factors. At the same time, during the driving of the vehicle, the devices are properly placed in the chamber 9, avoiding damage caused by vibration, collision, etc., extending the service life of the devices, and reducing the maintenance cost.

[0079] When the projection device 4 and the position adjustment mechanism 8 are not in use, the cover plate 10 is closed, and the entire chamber 9 is integrated with the vehicle interior trim, maintaining the cleanliness and beauty of the vehicle interior trim and not damaging the overall design style of the vehicle. Compared with the exposed devices, this hidden design better meets the requirements of modern automobiles for the beauty of the interior trim, improving the quality sense of the vehicle.

[0080] The chamber 9 is arranged at the backrest of the rear seat and / or the rear part of the center console box 20, facilitating the operation and use of the projection system by the rear passengers. The passengers can easily open the cover plate 10 and adjust the position and angle of the projection device 4 through the position adjustment mechanism 8 according to the target projection area information generated by the controller, so as to image the image to be displayed onto the target projection area 31 of the projection carrier 3, meeting the viewing needs of the passengers. After use, the device can be conveniently stored back into the chamber 9 and the cover plate 10 can be closed, with simple and convenient operation.

[0081] As a preferred embodiment of the present invention, as shown in Figure 1 The number of the projection devices 4 is multiple, and the projection direction of each projection device 4 corresponds to different projection areas 31 of the projection carrier 3 on the top of the vehicle interior, so as to meet the viewing needs of passengers in different positions.

[0082] The multiple projection devices 4 respectively corresponding to different projection areas of the projection carrier 3 means that passengers in different positions in the vehicle interior can watch different contents simultaneously. For example, for two rear passengers, one can watch a movie while the other can watch a game screen or make a video call, etc. This personalized setting fully meets the unique needs of each passenger, enhances the diversity and pertinence of the in-vehicle entertainment system, and enables each passenger to obtain a satisfactory entertainment experience. At the same time, in the case of multiple people riding in the vehicle, different projection contents can trigger communication and interaction among the passengers. For example, they can discuss the contents they watch and share their feelings, etc., increasing the social fun during the ride and making the ride not only a way of traveling but also an opportunity for socializing and entertainment.

[0083] And since each projection device 4 projects onto a specific projection area 31, it can be optimized and adjusted according to factors such as the position and angle of this area. Compared with a single projection device 4 covering the entire projection carrier 3, the multiple projection devices 4 can better ensure the clarity, brightness, and color restoration degree of the picture, avoiding the decline in picture quality caused by problems such as distance and angle, thereby providing passengers with a higher-quality visual enjoyment.

[0084] The seat layouts of vehicles are diverse, and the setting of multiple projection devices 4 can better adapt to different seat arrangements. Whether it is a two-row seat, a three-row seat, or other special seat layouts, by reasonably arranging the projection devices 4 and the projection areas 31 of the projection carrier 3, it can be ensured that passengers in each seat can have a suitable projection viewing position, improving the versatility and adaptability of the in-vehicle projection system.

[0085] When a certain projection device 4 fails, other projection devices 4 can still work normally without affecting the use of other passengers. This redundant design increases the reliability and flexibility of the system. Even if some devices have problems, the entire in-vehicle projection system will not completely break down, ensuring the continuous availability of the system.

[0086] As a preferred embodiment of the present invention, refer to Figure 1 As shown, the detection element 1 is a pressure sensor 11 arranged in the seat and / or a camera 12 arranged in the vehicle.

[0087] The pressure sensor 11 generally works based on principles such as piezoresistive effect, piezoelectric effect or capacitance effect. When the seat is subjected to pressure, the sensitive element in the pressure sensor 11 will undergo corresponding physical changes, such as changes in resistance value, charge quantity or capacitance value. These changes are proportional to the applied pressure. By measuring these physical quantity changes, the magnitude of the pressure borne by the seat can be known.

[0088] The method of detecting the occupant's position by the pressure sensor 11 arranged in the seat specifically includes: installing multiple pressure sensors 11 at different positions on the seat surface to form a pressure sensor array. When an occupant sits on the seat, the pressure sensors 11 at different positions will generate different electrical signal outputs according to the magnitude of the pressure received. For example, the pressure sensor 11 under the buttocks will output a stronger signal due to the greater pressure, while the pressure sensors 11 at the leg or shoulder positions output relatively weaker signals. By analyzing the signal distribution of these sensors, the positions of various parts of the occupant's body on the seat can be roughly judged, and then the occupant's sitting posture and approximate contour can be determined.

[0089] The pressure sensor 11 can not only detect the presence or absence of pressure, but also accurately measure the magnitude of the pressure. When the occupant changes the sitting posture or moves on the seat, the pressure distribution will change. The system can track the dynamic position change of the occupant on the seat by continuously monitoring the change of the pressure distribution of the pressure sensor array. For example, when the occupant leans forward, the pressure sensors 11 at the front of the seat will detect an increase in pressure, while the pressure of the pressure sensors 11 at the rear will decrease accordingly. Based on this, the forward movement and position change of the occupant's body can be judged.

[0090] Using the in-vehicle camera 12, information such as the position and posture of the occupant can be detected through image recognition technology. For example, it can be determined whether the occupant is sitting or lying on the seat, as well as the orientation of the head and body. To comprehensively and accurately obtain occupant information, cameras 12 are usually installed at multiple positions in the vehicle. For example, one or more cameras are installed at the front position on the top of the vehicle to overlook the seat area in the vehicle, so that the overall position and general posture of the occupant on the seat can be better captured. At the same time, cameras can also be installed on the sides of the front row and the rear row of the vehicle to observe the posture of the occupant from the side, especially the details such as the tilt angle of the head and body and the position of the arms.

[0091] To improve the accuracy and reliability of detection, the image information collected by multiple cameras 12 is fused and processed. For example, the detection results of the top camera and the side cameras are comprehensively analyzed to complement and verify each other. If the top camera detects the general position of the occupant on a certain seat, and the side camera also detects the human posture information at the corresponding position, then the position and posture of the occupant can be more determined. At the same time, the information of other sensors (such as pressure sensors, weight sensors, etc.) can also be combined for fusion to further optimize the detection and judgment of information such as the position and posture of the occupant. For example, when the pressure sensor detects a pressure change on the seat and the camera image recognition also finds a change in the occupant's posture at the corresponding position, the movement and position change of the occupant can be more accurately judged.

[0092] Furthermore, the camera 12 can also track the movement direction and fixation point of the occupant's eyes, and then infer the area that the occupant is concerned about, so as to assist in determining its relative position and viewing direction.

[0093] As a preferred embodiment of the present invention, as shown in Figure 2 the projection carrier 3 includes three projection areas 41, and the three projection areas 31 are arranged in sequence along the vehicle length direction, that is, the front-back direction. The three projection areas 31 arranged in sequence along the vehicle length direction respectively correspond to the front row, the rear row and the rear row folding position of the vehicle, and provide independent projection services for occupants in different positions. For example, when the driver or occupant in the front row is resting, they can use the corresponding projection area in the front row to watch entertainment content; the occupants in the rear row can use the latter two projection areas 31 to watch entertainment content such as movies and games. This zoning setting enables the in-vehicle projection system to adapt to the diverse needs of different occupants in different positions and improves the practicality of the system.

[0094] Further, each projection area 31 includes two left and right projection sub - areas, which means that two or three occupants in the same row can watch different contents simultaneously. For example, for two rear - row occupants, one can watch their favorite movie while the other can make a video call or play games without interference. Each occupant can choose appropriate projection content according to their own preferences and needs, greatly enhancing the personalized experience and meeting the interests and hobbies of different occupants.

[0095] Dividing the projection carrier 3 into multiple projection areas and sub - areas makes full use of the space resources on the top of the vehicle interior. Through reasonable layout, the projection system can provide more functions and services within a limited space without occupying other activity spaces inside the vehicle. At the same time, this zoning method also facilitates the arrangement and installation of projection devices. It can accurately adjust the projection direction and range of the projection device according to the positions and angles of different projection areas, improving the projection effect.

[0096] Since each projection area and sub - area is relatively independent, the projection device 4 can be optimized and set according to the specific conditions of each area, such as adjusting parameters like brightness, contrast, and focal length. Compared with a large - area projection area, this zoned projection method can better ensure the clarity and quality of each projection screen, providing a better visual enjoyment for the occupants.

[0097] In one embodiment, the present invention also discloses a vehicle, including the in - vehicle projection system described in any of the above - mentioned embodiments.

[0098] The in - vehicle projection system can provide diversified entertainment methods for the occupants, such as watching movies, playing games, etc. Multiple projection areas and flexible projection device adjustment functions can meet the personalized entertainment needs of different occupants, making the occupants no longer feel bored during the ride and greatly enhancing the entertainment experience of the ride. Whether it is a long - distance trip or daily commuting, it can create a pleasant riding environment for the occupants.

[0099] Enhancing comfort and convenience: The projection carrier is set on the top of the vehicle interior and does not occupy other activity spaces, and will not interfere with the normal sitting and activities of the occupants. At the same time, the design of the position adjustment mechanism and support structure of the projection device enables the occupants to easily adjust the position, angle, and size of the projection screen according to their own needs, obtaining the best viewing angle and effect, further enhancing the comfort and convenience of the ride.

[0100] In one embodiment, the present invention provides an in - vehicle projection control method. Refer to Figure 10 as shown, the control method includes the following steps: S1, detecting the in - vehicle occupant position information through the detection element 1 and sending the detection result to the controller 2.

[0101] After receiving the projection start instruction, the controller 2 controls the detection element 1 to detect the position information of the vehicle occupants, that is, uses the detection element 1 installed in the vehicle, such as seat sensors, cameras, eye tracking devices, etc., to detect the position information of the vehicle occupants. The detection element 1 obtains detailed information such as the specific position and posture of the occupants in the vehicle through their respective working principles. For example, the seat sensor determines whether the occupant is sitting on the seat and the general sitting posture by sensing the pressure distribution on the seat; the camera accurately identifies the position and body posture of the occupant through image recognition technology.

[0102] The detection element 1 sends the detected result to the controller 2 in the form of an electrical signal or a digital signal.

[0103] The projection start instruction is that the user presses a physical start button or a touch start button, or the user controls the projection start through a voice instruction.

[0104] S2. The controller 2 receives the detection result of the detection element 1, determines the target projection area information based on the detection result, and sends the target projection area information to the projection device 4 located inside the vehicle.

[0105] Specifically, after receiving the detection result transmitted by the detection element 1, the controller 2 analyzes and processes this information. The controller 2 determines a suitable projection area according to a preset algorithm and logic rule, in combination with the detected occupant position information. For example, if a passenger is detected in the left rear seat and the passenger is in a normal sitting posture, the controller will generate an instruction, that is, the target projection area information, and set the projection area of the projection device 4 to the target projection area above the corresponding left rear seat.

[0106] S3. The projection device 4 receives the target projection area information of the controller 2 and projects the image to be displayed onto the target projection area of the projection carrier 3 located on the top of the vehicle interior.

[0107] Specifically, after receiving the target projection area information sent by the controller 2, the projection device 4 adjusts its own projection parameters, such as projection angle, focal length, brightness, etc., to ensure that the image to be displayed can be accurately projected onto the target projection area of the projection carrier 3 on the top of the vehicle interior. For example, the projection device 4 may adjust the angle of the lens so that the image can be perfectly projected onto the specified projection area, and adjust the brightness according to the ambient light to ensure the clarity and visibility of the image.
