[0049] The present 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 includes:

[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 to be slidably connected to the roof;

[0052] The curtain assembly 200 includes a curtain body 210 and a traction box 220. The curtain body 210 is connected to the traction box 220. The traction box 220 is slidably connected to the roof and can move vertically.

[0053] The projector 300 is provided in the vehicle and is used for projecting images toward 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 unfolded at least vertically under the action of the traction box 220.

[0055] The technical solution of the present invention is to set the sunshade assembly 100 and the screen assembly 200 at the position of the sunroof of the vehicle, and use the screen assembly 200 and the sunshade assembly 100 in combination so that the screen 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 cover the sunroof on the roof, and the screen body 210 of the screen assembly 200 slides and unfolds along the roof with the traction box 220, and the projector 3 00 projects images toward the screen body 210 for the driver and passengers in the car, especially the front row passengers to rest and watch, or to create an atmosphere of starry sky, ocean, laser, etc.; it also has a second display state, and the sunshade body 110 of the sunshade assembly 100 can be used to slide and unfold 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 car, and the projector 300 projects onto 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 car. 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 level 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 can be 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 can be 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 can be 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] In particular, regarding the vertical movement of the traction box 220, a movable structure may be provided within the traction box 220, which is capable of vertical movement, thereby pulling the screen body 210 to vertically unfold, thereby entering the second display state. At this time, the screen body 210 may be tilted and unfolded between one side fixed to the side of the vehicle roof and the movable lower portion of the traction box 220, thereby having a vertical unfolding component, or it may be completely unfolded vertically after the top of the traction box 220 is reversed. Alternatively, after the main box 120 and the traction box 220 abut, the movable structure provided within the main box 120 guides the structure in the traction box 220 connected to the screen body 210 to move downward, thereby switching the screen body 210 to the second display state, thereby reducing the volume of the traction box 220 and providing support for the vertically unfolded portion of the screen in the second display state, thereby 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 position of the curtain body 210 in the vertical direction when 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 fixture 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 fixture, 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 fixture 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 of the driver and passengers, in one embodiment, please refer to Figure 1 and Figure 2, the projector 300 is arranged on the armrest box 401 of the front row of seats, and when the curtain body 210 is in the first display state, the projector 300 on the armrest box 401 projects upward, which is suitable for the driver and the passenger to watch from bottom to top, and at this time, it is more suitable for the driver and the passenger to watch in a lying position after the front row of seats 402 is tilted; when the curtain body 210 is in the second display state, the curtain body 210 forms a partition between the front row of seats and the rear row of seats, and by adjusting the lens of the projector 300 on the armrest box 401, the projector 300 can project on the curtain body 210 in a vertical unfolding posture, which is suitable for the rear row of passengers to watch. In another embodiment, please refer to Figure 12 and Figure 13 , the projector 300 can also be arranged on the rear row of seats, such as being placed on the backrest of the rear row of seats 403 or the cup holder of the rear row of seats 403, and correspondingly, when the curtain body 210 is in the first display state, the projector 300 projects obliquely forward, which is suitable for the driver and the passenger to watch from bottom to top, at this time, it is more suitable for the driver and the passenger to watch in a lying position after the front row of seats 402 is tilted, or to provide the whole vehicle with atmosphere effects such as starry sky, ocean, aurora, etc.; when the curtain body 210 is in the second display state, the curtain body 210 forms a partition between the front row of seats and the rear row of seats, and by adjusting the posture of the projector 300, the lens of the projector 300 can project on the curtain body 210 in a vertical unfolding posture, which is suitable for the rear row of passengers to watch. Of course, in other embodiments, the projector 300 can also be arranged on the door, the floor of the vehicle, etc., and by adjusting the posture or the lens of the projector 300, the projector 300 can project on the curtain body 210 in the first display state and the second display state, respectively.

[0059] In an embodiment, please refer to Figure 2 and Figure 5The traction box 220 comprises 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, and the fixed end 221 is used to be slidingly connected to the roof; in the second display state, the fixed end 221 and the movable end 222 are vertically spaced apart, the curtain body 210 is connected through the fixed end 221 and the movable end 222, 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 force at both the fixed end 221 and the movable end 222, and the curtain body 210 is first bypassed around the fixed end 221 and then connected to the movable end 222, so that in the second display state, the fixed end 221 and the movable end 222 are vertically spaced apart, and the curtain body 210 forms a certain tension between the two, thereby ensuring that the curtain can be kept flat when it is vertically unfolded, avoiding wrinkles or corrugations, which helps 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 simplified, so that when the curtain body 210 does not need to be completely unfolded, the traction box 220 can maintain a smaller size to reduce the occupation of the space in the vehicle or the obstruction to the view of the driver and passengers. Of course, in other embodiments, after the traction box 220 and the main box 120 abut, the end of the curtain body 210 will be connected to the traction box 220, and the movable structure in the traction box 220 will be used to vertically unfold the curtain body 210 to switch to the second display state.

[0060] Further, in the present embodiment, please refer to Figure 5 , Figure 7 and Figure 8, the main box 120 comprises a box body 121 and a traction end 127 connected to the box body 121 and vertically movable relative to the box body 121, and the box body 121 is used to be slidingly connected to the roof; in the second display state, the traction end 127 is connected to the movable end 222 and 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 unfolded vertically. Thus, the main box 120 provided on the sunshade assembly 100 to control the curtain body 210 to unfold vertically can reduce the volume of the traction box 220 and balance the volume of the main box 120 and the traction box 220, avoiding the volume of the single traction box 220 being too large to affect the user's view in the car. At the same time, when the curtain body 210 needs to be switched into the second display state, the main box 120 of the sunshade assembly 100 slides towards the traction box 220 and connects the traction end 127 to the movable end 222 of the traction box 220 to control the curtain body 210 to unfold vertically. At this time, the sunshade body 110 also unfolds in the area of the roof except the curtain body 210 to form a light-shielding barrier behind the curtain body 210, thereby reducing the influence of the light shining through the sunroof on the projection quality of the projector 300. In addition, the connection of the traction end 127 and the movable end 222 and their vertical spacing relative to the box body 121 still ensures that the curtain body 210 can maintain a certain tension and stability during vertical unfolding, thereby ensuring the clarity of the projection picture and the viewing effect.

[0061] For the connection mode of the main box 120 and the traction box 220, in an embodiment, please refer to Figure 5 、 Figure 9 and Figure 10, the box body 121 is provided with a first locking member 126, the traction end 127 is provided with a second locking member 128, in the second display state, the first locking member 126 and the fixed end 221 are locked and connected, and the second locking member 128 and the movable end 222 are locked and connected. It should be noted that the first locking member 126 and the second locking member 128 can be driven by electric power or other external force to lock or separate 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, and have magnetism when powered on and lose magnetism when powered off, thereby realizing 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 examples, 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. During switching of the curtain body 210 to the second display state, the box body 121 first adsorbs the fixed end 221 through the first locking member 126, and the traction end 127 also adsorbs 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 expanding the curtain body 210 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 of the box body 121 and the fixed end 221, and the traction end 127 and the movable end 222, improves the switching convenience of the curtain body 210 between the first display state and the second display state, and at the same time, guarantees the stability of the curtain body 210 switching to the second display state through the magnetic adsorption. Of course, in other embodiments, the box body 121 and the fixed end 221 can be connected by plugging, and the traction end 127 and the movable end 222 can be connected by plugging.

[0062] For the viewing and entertainment projection application of the rear passengers, the vehicle-mounted partition projection curtain in the related art is only stable in the completely expanded state, and is unstable in the partially expanded state. The structure in the related art limits the flexible application of projection. Moreover, the excessively large curtain greatly separates the front row and the rear row in some scenes, which limits the communication between the front row passengers and the rear row passengers, such as the case of separate viewing of projection by parents in the front row and children in the rear row, and the parents cannot watch the state of the children.

[0063] In an 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 provided 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 position, thereby pushing the traction end 127 to move downward, thereby pulling the movable end 222 to slide downward, thereby realizing the vertical expansion of the curtain body 210; for the upward retraction 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 and away from each other, or continuously away from each other, so that the connecting rod 129 switches back to the horizontal position, thereby pulling 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, thereby realizing the vertical retraction of the curtain body 210. In this way, the vertical position of the traction end 127 can be controlled based on the position of the slider 123 on the slide bar 122, thereby flexibly adjusting the vertical extension of the screen body 210 to meet different projection size requirements and viewing options, enriching projection applications. In particular, when the screen body 210 is in the second display state, the vertical extension of the screen body 210 can be adaptively adjusted according to the communication and rest needs of front and rear row passengers, ensuring flexibility in projection use. Simultaneously, the vertically repositioned connecting rod 129 also provides support for the screen body 210, ensuring its stability in the second display state and thus maintaining the projection effect. Of course, in other embodiments, the box body 121 can also control the vertical movement of the traction end 127 via a telescopic rod, thereby driving the vertical expansion and retraction of the screen body 210.

[0064] It can be understood that according to the above-mentioned technical solution of the sliding rod 122 and the connecting rod 129 controlling the vertical extension of the screen body 210, and the technical solution of the telescopic rod controlling the vertical extension of the screen body 210, it can be seen 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 expansion area in the vertical direction, the stability of the screen body 210 can be ensured, thereby improving the user convenience.

[0065] Further, in this embodiment, please refer to Figures 7 to 9The main box 120 also includes a drive assembly disposed on the box body 121. The drive 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, causing the two sliders 123 to slide in opposite directions. Without loss of generality, the drive 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 via the transmission assembly 125 and can simultaneously drive the two slide bars 122 to rotate in opposite directions. Compared to using two motors to drive the two slide bars 122, this can reduce the size of the main box 120 and reduce the noise generated by driving the two slide bars 122 to rotate. In addition, a single main box motor 124 drives the two slide bars 122 to rotate, effectively ensuring the synchronization of the rotation of the two slide bars 122, ensuring that the movement speed of the slider 123 tends to be consistent, and thus ensuring that the two connecting rods 129 change their posture at a consistent frequency, ensuring that the traction end 127 remains horizontal and moves vertically, thereby ensuring the smoothness and stability of the vertical movement of the curtain body 210. Of course, in other embodiments, two motors may also be used to drive the two slide bars 122 to rotate in opposite directions.

[0066] Regarding the connection relationship between the traction end 127 and the connecting rod 129, in one embodiment, please refer to Figure 8 and Figure 10 The traction end 127 is configured as a crossbar, with two connecting rods 129 rotatably connected to each end of the crossbar. It should be noted that in the stowed state and the first display state, the connecting rod 129 and the slide bar 122 extend horizontally, with similar or equal lengths. When the connecting rod 129 switches from a horizontal position to a vertical position, the sliders 123 of the two slide bars 122 first slide toward each other at the distal ends of the corresponding slide bars 122 until they meet, and then slide in opposite directions from the meeting point to the other end of the corresponding slide bar 122. Thus, when the screen body 210 is in the second display state, the two connecting rods 129 support the vertically extending sides of the screen body 210, thereby forming a square-shaped support structure with the box body 121 and the traction end 127. This effectively prevents the screen from shaking due to factors such as gravity or external forces, ensuring that the screen body 210 remains flat and stable. At the same time, by flexibly controlling the position of the slider 123 relative to the slide bar 122, the vertical extension of the screen body 210 can be flexibly adjusted while the connecting rod 129 can maintain its support function for the screen body 210, ensuring that the screen body 210 has good stability at any vertical extension, ensuring the projection effect, and improving user convenience. Of course, in other embodiments, the end of the connecting rod 129 can also be rotatably connected to the middle of the pulling end 127 in the horizontal direction.

[0067] Regarding the projection of the projector 300 on the screen body 210 in the first display state and the second display state, in one embodiment, please refer to Figure 1、 Figure 2 and Figure 11 The projector 300 includes a device body 310 and a first lens 320 and a second lens 330. At least one of the first lens 320 and the second lens 330 is movably connected to the device body 310. In a first display state, the first lens 320 projects toward the screen body 210, and in a second display state, the second lens 330 projects toward the screen body 210. It will be understood that, depending on the placement of the device body 310, the first lens 320 may be movably connected to the device body 310, the first lens 320 may be movably connected to the device body 310, or both the first lens 320 and the second lens 330 may be movably connected to the device body 310. In this way, the projector 300 can adjust the projection direction according to the first display state and the second display state, ensuring that the projection light is accurately projected onto the screen body 210, thereby optimizing the projection effect. Specifically, with the projector 300 disposed in the front console box 401 of the vehicle, in this embodiment, when the screen body 210 is in the first display state, the first lens 320 of the projector 300 is a telephoto lens and projects upward onto the screen body 210. When the screen body 210 is in the second display state, the short-focus lens of the projector 300, i.e., the second lens 330, is adjusted to accommodate the screen body 210 closer to the projector 300, thereby ensuring the clarity of the image projected on the screen body 210. Of course, in other embodiments, the posture of the projector 300 can also be adjusted to adapt to the screen body 210 in the first and second display states.

[0068] In one embodiment, please refer to Figures 3 to 5 The projector 300 is also provided with an adjustment member. In the first display state or the second display state, the screen body 210 has a preset display area, and the adjustment member is used to adjust the projection range of the projector 300 to adapt to the preset display area. Referring to the above description of the screen body 210 being able to flexibly adjust its degree of expansion and maintain stability in the first and second display states, the preset display area is the maximum display area of ​​the screen body 210 available for projection in the second display state or a user-selectable display area. If the unfolded size of the screen body 210 varies, the adjustment member can adjust the position of the projector 300 lens projected onto the screen so that the projection area corresponds to the size of the screen edge. The adjustment member can be a lens of the projector 300 with an automatic zoom function, or it can be an algorithm module within the projector 300 that adjusts the projection range of the projector 300 to adapt to the preset projection area based on projection requirements and the size of the preset display area. This achieves the effect of variable display size of the projected image, enhancing the user experience.

[0069] In one embodiment, please refer to Figures 3 to 5The sunshade assembly 100 further includes a sunshade reel 130 and a first drive member. The first drive member is drivably connected to the sunshade reel 130 and can drive the main box 120 to slide along the vehicle roof. The sunshade body 110 is retractably connected to the sunshade reel 130. By driving the sunshade reel 130 with the first drive member, the sunshade body 110 can automatically switch between a first display state and a retracted state, respectively. This allows the vehicle-mounted projection device to adapt to different usage environments and viewing needs. For example, when shading is needed during the day, the sunshade body 110 can be unfolded to reduce the impact of sunlight on the projection on the screen body 210. At the same time, the precise control of the first drive member allows the sunshade body 110 to automatically adjust its degree of unfolding according to actual needs. For example, when sunlight is strong, the sunshade body 110 can be fully unfolded to provide maximum shading effect. The sunshade reel 130 can be disposed on the side of the vehicle roof, with the main box 120 sliding relative to the sunshade reel 130. The sunshade body 110 can have one end fixedly connected to the main box 120 and the other end retractably connected to the sunshade reel 130. Alternatively, the sunshade reel 130 can be disposed on the main box 120, with one end of the sunshade body 110 fixedly connected to the side of the vehicle roof and the other end retractably connected to the sunshade reel 130 within the main box 120. Furthermore, a first drive member enables the main box 120 to automatically slide along the vehicle roof, thereby enhancing the convenience of switching the sunshade body 110 between the retracted state and the first display state. The vehicle roof is provided with a guide structure such as a slide rail for the main box 120 to slide. Of course, in other embodiments, the sunshade reel 130 can be manually controlled to adjust the deployment and retraction of the sunshade body 110, or the main box 120 can be manually controlled to slide along the vehicle roof.

[0070] Similarly, in one embodiment, please refer to Figures 3 to 5The screen assembly 200 also includes a screen reel 230 and a second drive member.
