[0049] The invention provides a vehicle-mounted projection device.

[0050] Please refer to Figures 1 to 5 In one embodiment of the present invention, the vehicle-mounted projection device comprises:

[0051] The sunshade assembly 100 is provided with a main box 120 and a sunshade body 110, the sunshade body 110 is connected to the main box 120, and the main box 120 is used for sliding connection to the roof of the vehicle;

[0052] The curtain assembly 200 is provided with a curtain body 210 and a traction box 220, wherein the curtain body 210 is connected to the traction box 220, and the traction box 220 is used for being slidably connected to the roof of the vehicle and can move vertically; and

[0053] A projector 300 is disposed in the vehicle and is used for projecting onto the screen body 210;

[0054] Among them, the curtain assembly 200 and the sunshade assembly 100 have a storage state, a first display state and a second display state. In the storage state, the sunshade body 110 and the curtain body 210 avoid the roof. In the first display state, at least the curtain body 210 is unfolded along the roof. In the second display state, the curtain body 210 is at least unfolded vertically under the action of the traction box 220.

[0055] The technical solution of the present invention adopts the sunshade assembly 100 and the curtain assembly 200 to be arranged at the position of the sunroof of the vehicle, and the curtain assembly 200 and the sunshade assembly 100 are used in coordination, so that the curtain assembly 200 and the sunshade assembly 100 have a storage state, thereby avoiding the sunroof on the roof and ensuring the normal use of the sunroof; in the first display state, the shielding body of the sunshade assembly 100 can be used to slide and unfold with the main box 120 to shield the sunroof on the roof, and the curtain body 210 of the curtain assembly 200 slides and unfolds along the roof with the traction box 220, and the projector 3 00 projects images onto the screen body 210 for the driver and passengers in the vehicle, especially those in the front row, to rest and watch, or to create an atmosphere of starry sky, ocean, laser, etc.; it also has a second display state, in which the sunshade body 110 of the sunshade assembly 100 can be slid and unfolded with the main box 120 to block the skylight on the roof, and the screen body 210 of the screen assembly 200 can be unfolded vertically downward with the traction box 220 to form a partition screen between the front and rear rows in the vehicle, and the projector 300 projects on the vertically unfolded screen body 210 for the passengers in the back row to rest and watch. In this way, the sunshade assembly 100 can realize the sunshade function, and be used in conjunction with the screen assembly 200 to reduce the interference of external sunlight on the projection inside the vehicle. The sunshade assembly 100 can even promote the switching of the screen assembly 200 between various states. At the same time, the screen assembly 200 has a storage state, a first display state and a second display state, which meets the needs of different drivers and passengers and different viewing postures, broadens the use scenarios of vehicle-mounted projection, and is conducive to improving the frequency and flexibility of use of screen projection, thereby increasing the application of vehicle-mounted projection devices in automobiles and improving the user experience.

[0056] It should be noted that the main box 120 and the traction box 220 slide along the roof in the length direction of the vehicle. During the sliding of the main box 120, the sunshade body 110, that is, the sunshade curtain, is unfolded. The sunshade curtain can be fixed at one end and the other end is rolled up in the main box 120, or one end is fixed in the main box 120 and the other end is rolled up on the side of the roof; correspondingly, during the sliding of the traction box 220, the curtain body 210, that is, the curtain, is unfolded. The curtain body 210 can be fixed at one end and the other end is rolled up in the traction box 220, or one end is fixed in the traction box 220 and the other end is rolled up on the side of the roof. In addition, the sunshade body 110 of the sunshade assembly 100 and the sunshade body 110 of the curtain assembly 200 can be staggered and unfolded in parallel, and the sunshade body 110 is arranged closer to the roof than the curtain body 210. Here, combined with the following description of the main box 120 driving the traction box 220 to move downward, the main box 120 can be split vertically and can move vertically on the side away from the traction box 220 to drive the traction box to move vertically, and then pull the curtain body 210 to unfold vertically, thereby switching to the second display state; alternatively, the sunshade body 110 and the curtain body 210 can also be arranged on the same layer, and the unfolding area of ​​the curtain body 210 and the sunshade body 110 is controlled by the positional relationship between the main box 120 and the traction box 220. As for the distribution of the sunshade assembly 100 and the curtain assembly 200 in the storage state, the two can be distributed on both sides along the width direction of the roof; or they can be distributed on both sides along the length direction of the roof, such as the curtain assembly 200 is distributed on the rear side of the roof and the sunshade assembly 100 is distributed on the front side of the roof; or, the sunshade assembly 100 and the curtain assembly 200 are arranged on the same side of the roof skylight position.

[0057] Among them, as for the mode in which the traction box 220 can move vertically, a movable structure can be set in the traction box 220, and the movable structure can move vertically, thereby pulling the screen body 210 to unfold vertically, and then the second display state. At this time, the posture of the screen body 210 can be tilted and unfolded between one side fixed to the side of the roof and the movable lower part of the traction box 220 to have a vertical unfolding component, or it can be completely unfolded vertically after the top of the traction box 220 is reversed. Alternatively, it can also be that after the main box 120 and the traction box 220 are abutted, the movable structure set in the main box 120 guides the structure connected to the screen body 210 in the traction box 220 to move downward, so that the screen body 210 switches to the second display state, thereby reducing the volume of the traction box 220, and also providing support for the vertical unfolding part of the screen in the second display state, ensuring the stability of the image projected by the projector 300. Without loss of generality, the traction box 220 can be located at any position on the roof along the length of the vehicle to flexibly control the degree of expansion of the curtain body 210 in the first display state and the vertical expansion position of the curtain body 210 in the second display state. As for the switching relationship between the curtain body 210 in the first display state and the second display state, the curtain body 210 can first enter the first display state and then enter the second display state, or the curtain body 210 can independently switch from the storage state to the first display state or the second display state. If the curtain body 210 is rolled up in the traction box 220, the first display state can be achieved by providing a clamping piece on the side of the roof. After the traction box 220 moves to the side, one end of the curtain body 210 is clamped by the clamping piece, and then the traction box 220 slides along the roof to unfold the curtain body 210. When the traction box 220 slides to the side again, the clamping piece releases the clamping effect on the curtain body 210, so that the curtain body 210 enters the storage state. Correspondingly, the second display state can be achieved by moving the traction box 220 to any position and being able to move vertically through the movable structure in the traction box 220, thereby pulling the curtain body 210 to unfold vertically.

[0058] Regarding the placement of the projector 300 and the suitability for the driver and passengers, in one embodiment, please refer to Figure 1 and Figure 2The projector 300 is arranged on the armrest box 401 of the front row of the vehicle. Correspondingly, when the screen body 210 is in the first display state, the projector 300 on the armrest box 401 projects upwards, which is suitable for the driver and passengers to watch movies from bottom to top. At this time, it is more suitable for the driver and passengers to watch movies lying down after the front seats 402 of the vehicle are tilted; when the screen body 210 is in the second display state, the screen body 210 will form a partition between the front row and the rear row of the vehicle. By adjusting the lens of the projector 300 on the armrest box 401, the screen body 210 in the vertically unfolded posture can be projected, which is suitable for the passengers in the rear row to watch movies. In another embodiment, please refer to Fig.12 and Fig.13 , the projector 300 can also be set in the rear row of the vehicle, such as placed on the backrest of the rear seat 403, or the cup holder of the rear seat 403. Correspondingly, when the screen body 210 is in the first display state, the projector 300 tilts forward for projection, which is suitable for the driver and passengers to watch movies from bottom to top. At this time, it is more suitable for the driver and passengers to watch movies lying down after the front seat 402 of the vehicle is tilted, or to provide the whole vehicle with atmosphere effects such as starry sky, ocean, and aurora; when the screen body 210 is in the second display state, the screen body 210 will form a partition between the front row and the rear row of the vehicle. By adjusting the posture of the projector 300, the lens of the projector 300 can project the screen body 210 in the vertical unfolding posture, which is suitable for the rear passengers to watch movies. Of course, in other embodiments, the projector 300 can also be set at the door, the floor of the vehicle, etc., and by adjusting the posture or lens of the projector 300, the screen body 210 in the first display state and the second display state can be projected respectively.

[0059] In one embodiment, please refer to Figure 2 and Figure 5The traction box 220 includes a fixed end 221 and a movable end 222. The movable end 222 is connected to the curtain body 210 and can move vertically relative to the fixed end 221. The fixed end 221 is used to be slidably connected to the roof. In the second display state, the fixed end 221 and the movable end 222 are arranged vertically at intervals. The curtain body 210 is connected to the movable end 222 via the fixed end 221. In the first display state and the storage state, the fixed end 221 and the movable end 222 are connected. It can be understood that the curtain body 210 is subjected to forces at both the fixed end 221 and the movable end 222, so that the curtain body 210 first bypasses the fixed end 221 and then connects to the movable end 222. In this way, in the second display state, the fixed end 221 and the movable end 222 are arranged vertically at intervals, and the curtain body 210 forms a certain tension between the two, thereby ensuring that the curtain can remain flat when it is vertically unfolded, avoiding wrinkles or ripples, and helping to ensure the clarity and visual effect of the projection picture. At the same time, in the first display state and the storage state, the fixed end 221 and the movable end 222 are connected, which means that the structure for switching the positions of the fixed end 221 and the movable end 222 in the traction box 220 can be relatively simplified, so that when the curtain body 210 does not need to be fully unfolded, the traction box 220 can maintain a small volume to reduce the space occupied in the vehicle or block the sight of the driver and passengers. Of course, in other embodiments, after the traction box 220 and the main box 120 are abutted, the end of the curtain body 210 will be connected to the traction box 220, and the curtain body 210 can be vertically unfolded by the movable structure in the traction box 220 to switch to the second display state.

[0060] Further, in this embodiment, please refer to Figure 5 , Figure 7 and Figure 8The main box 120 includes a box body 121 and a traction end 127. The traction end 127 is connected to the box body 121 and can move vertically relative to the box body 121. The box body 121 is used for sliding connection to the roof. In the second display state, the traction end 127 is connected to the movable end 222 and is vertically spaced apart from the box body 121. It can be understood that the traction end 127 of the main box 120 drives the movable end 222 of the traction box 220 to move vertically so that the curtain body 210 is vertically unfolded. In this way, the main box 120 with a structure for controlling the vertical unfolding of the curtain body 210 is set on the sunshade assembly 100, which can reduce the volume of the traction box 220 and balance the volume of the main box 120 and the traction box 220, so as to avoid the single traction box 220 from being too large and affecting the user's field of vision in the car. At the same time, when the screen body 210 needs to switch to the second display state, the main box 120 of the sunshade assembly 100 slides toward the traction box 220, and the traction end 127 is connected to the movable end 222 of the traction box 220 to control the screen body 210 to unfold vertically. At this time, the sunshade body 110 is also correspondingly unfolded in the area of ​​the roof except the screen body 210 to form a light shielding for the area behind the screen body 210, thereby reducing the impact of the light irradiated through the roof skylight on the projection quality of the projector 300. In addition, the connection between the traction end 127 and the movable end 222, and their vertical spacing relative to the box body 121, still ensure that the screen body 210 can maintain a certain tension and stability during the vertical unfolding process, thereby ensuring the clarity of the projected image and the viewing effect.

[0061] Regarding the connection method between the main box 120 and the traction box 220, in one embodiment, please refer to Figure 5 , Fig. 9 and Fig.10, the box body 121 is provided with a first locking member 126, and the traction end 127 is provided with a second locking member 128. In the second display state, the first locking member 126 is locked and connected with the fixed end 221, and the second locking member 128 is locked and connected with the movable end 222. It should be noted that the first locking member 126 and the second locking member 128 can be driven by other external forces such as electricity to respectively lock or loosen the fixed end 221 and the movable end 222. For example, the first locking member 126 and the second locking member 128 are electromagnetic objects, which are magnetic when powered on and lose their magnetism when powered off, thereby achieving the locking or separation of the fixed end 221 and the movable end 222 by electromagnetic force. Taking the first locking member 126 and the second locking member 128 as electromagnetic objects as an example, in this embodiment, the fixed end 221 of the traction box 220 is provided with a magnetic material, and the movable end 222 is also provided with a magnetic material. When the curtain body 210 switches to the second display state, the box body 121 firstly absorbs the fixed end 221 through the first locking member 126, and then the traction end 127 also absorbs the movable end 222 through the second locking member 128, so that when the traction end 127 moves vertically, the movable end 222 also moves vertically synchronously, thereby pulling the curtain body 210 to unfold vertically. In this way, the introduction of the first locking member 126 and the second locking member 128 greatly simplifies the connection and separation process between the box body 121 and the fixed end 221, and the traction end 127 and the movable end 222, and improves the convenience of switching the curtain body 210 between the first display state and the second display state. At the same time, the stability of the curtain body 210 switching to the second display state is guaranteed by magnetic adsorption. Of course, in other embodiments, the box body 121 and the fixed end 221 may also be connected by plugging, and the pulling end 127 and the movable end 222 may also be connected by plugging.

[0062] For the projection application of movie viewing and entertainment for rear passengers, the in-vehicle partition projection screen in the related art is only stable when fully unfolded, and unstable when partially unfolded. Such structures in the related art limit the flexible application of projection. In addition, the overly large screen greatly separates the front and back rows in some scenes, limiting the communication between the front and back passengers. For example, when parents are in the front row and children are in the back row watching the projection alone, the parents cannot see the status of their children.

[0063] In one embodiment, please refer to Figures 6 to 9The main box 120 also includes two connecting rods 129. The box body 121 is provided with two sliding rods 122. One sliding rod 122 is provided with a slider 123. One end of a connecting rod 129 is rotatably connected to a slider 123, and the other end is rotatably connected to the traction end 127. In the storage state or the first display state, the two sliders 123 are respectively arranged at different ends of the two sliding rods 122. It can be understood that in the process of switching the curtain body 210 from the first display state to the second display state, the two sliders 123 on the two slide bars 122 first slide toward each other, so that the connecting rod 129 tilts downward from the horizontal posture, and then pushes the traction end 127 to move downward, thereby pulling the movable end 222 to slide downward, and realizing the vertical expansion of the curtain body 210; for the upward rolling of the curtain body 210 to exit the second display state, after the connecting rod 129 is in the vertical state, the sliders 123 on the two slide bars 122 slide in opposite directions again, which can be toward each other and then away from each other, or can be continuously away from each other, so that the connecting rod 129 switches back to the horizontal posture, and then pulls the traction end 127 to move upward to connect to the box body 121, thereby driving the movable end 222 to move upward to connect to the fixed end 221, and realizing the vertical rolling of the curtain body 210. In this way, the vertical position of the traction end 127 can be controlled according to the position of the slider 123 on the slide bar 122, so as to flexibly adjust the vertical expansion degree of the curtain body 210 to meet different projection size requirements and viewing options, enriching the projection application, especially when the curtain body 210 is in the second display state, the vertical expansion degree of the curtain body 210 can be adaptively adjusted according to the communication and rest needs of the front and rear passengers, so as to ensure the flexibility of projection. At the same time, the connecting rod 129 that changes its posture vertically also provides support for the curtain body 210, ensuring the stability of the curtain body 210 in the second display state, thereby ensuring the projection effect. Of course, in other embodiments, the box body 121 can also control the traction end 127 to move vertically through the telescopic rod, thereby driving the curtain body 210 to unfold and retract vertically.

[0064] It can be understood that according to the above-mentioned technical solution about the sliding rod 122 and the connecting rod 129 controlling the vertical extension of the screen body 210, and the technical solution about the telescopic rod controlling the vertical extension of the screen body 210, it can be known that in the second display state, at least the vertically distributed part of the screen body 210 can remain stable. Combined with the fact that the screen body 210 can flexibly adjust the unfolded area vertically, the stability of the screen body 210 can be ensured, thereby improving the user's convenience.

[0065] Further, in this embodiment, please refer to Figures 7 to 9The main box 120 also includes a driving assembly arranged on the box body 121, and the driving assembly is driven and connected to the two slide bars 122. In the second display state, the two slide bars 122 rotate in opposite directions to make the two sliders 123 slide in opposite directions. Without loss of generality, the driving assembly includes a main box motor 124 and a transmission assembly 125. One main box motor 124 is connected to the two slide bars 122 through the transmission assembly 125, and can simultaneously drive the two slide bars 122 to rotate in opposite directions. Compared with using two motors to drive the two slide bars 122 to rotate, the volume of the main box 120 can be reduced, and at the same time, the noise generated by driving the two slide bars 122 to rotate is also reduced. In addition, one main box motor 124 drives the two slide bars 122 to rotate, which can effectively ensure the synchronization of the rotation of the two slide bars 122, ensure that the moving speed of the slider 123 tends to be consistent, and then ensure that the frequency of the posture change of the two connecting rods 129 is consistent, and ensure that the traction end 127 remains horizontal and moves vertically, thereby ensuring the flatness and stability of the curtain body 210 when it is unfolded along the vertical movement. Of course, in other embodiments, the two sliding rods 122 may be driven to rotate in opposite directions by two motors respectively.

[0066] Regarding the connection relationship between the traction end 127 and the connecting rod 129, in one embodiment, please refer to Figure 8 and Fig.10 , the traction end 127 is configured as a crossbar, and the two connecting rods 129 are rotatably connected to the two ends of the crossbar. It should be noted that in the storage state and the first display state, the connecting rod 129 and the slide bar 122 are similar or equal in length and extend horizontally. In the process of switching the connecting rod 129 from the horizontal posture to the vertical posture, the sliders 123 of the two slide bars 122 first slide towards each other at the ends of the corresponding slide bars 122 that are far away from each other until they meet, and then slide from the meeting to the other end of the corresponding slide bar 122 in the opposite direction. In this way, when the curtain body 210 is in the second display state, the two connecting rods 129 support the two sides of the curtain body 210 extending vertically, thereby forming a square-shaped support structure with the box body 121 and the traction end 127, effectively preventing the curtain from shaking due to factors such as gravity or external forces, and ensuring that the curtain body 210 remains flat and stable. At the same time, by flexibly controlling the position of the slider 123 corresponding to the slider 122, the degree of vertical extension of the curtain body 210 can be flexibly adjusted, and the connecting rod 129 can also maintain the supporting function of the curtain body 210, ensuring that the curtain body 210 can have good stability under any vertical extension degree, ensuring the projection effect, and improving the user's convenience. Of course, in other embodiments, the end of the connecting rod 129 can also be rotatably connected to the middle of the traction end 127 in the horizontal direction.
