Description

TECHNICAL FIELD

[0001] The present application relates to an automobile part, in particular to a projection screen assembly and a vehicle. BACKGROUND

[0002] With the rapid development of the automobile industry, the vehicle-mounted projection function has gradually become an important development direction of cabin entertainment. Although the related vehicle-mounted projection technology continues to progress, it is limited by the particularity of the vehicle-mounted scene, and there is a significant gap between its application effect and that of home indoor projection. In the home projection scene, the installation environment of the projection screen is stable, and it does not need to cope with dynamic interference, and can maintain a fixed posture for a long time to ensure the viewing effect. However, in the vehicle-mounted scene, the existing technical solutions need to rely on specific conditions to achieve the best projection effect, for example, the vehicle needs to be placed in a stationary state, and the installation position and angle of the projection screen need to be strictly fixed to avoid the initial posture deviation affecting the picture presentation. Once the above specific conditions are deviated, such as the vehicle is in a driving state, affected by dynamic working conditions such as acceleration, deceleration, road bumps, and sudden braking, the support and driving structure of the existing vehicle-mounted projection screen is difficult to maintain stability, and the screen is easy to shake irregularly with the vehicle, resulting in the displacement and blurring of the projection picture, which seriously damages the user's viewing experience.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0023] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a projection screen assembly in some embodiments of this application. The projection screen assembly 100 includes a screen 110 and a guide rail 120. The screen 110 unfolds along its unfolding direction a or retracts along its retracting direction b, wherein the unfolding direction a and the retracting direction b are opposite. The guide rail 120 is used to connect to a third-party component 300. During the unfolding or retracting of the screen 110, the extension direction of the guide rail 120 is parallel to the unfolding direction a and the retracting direction b of the screen 110, and both sides of the screen 110 are connected to the guide rail 120. The guide rail 120 is used to guide the unfolding or retracting direction of the screen 110 and to limit the swing amplitude of the screen 110 when it is unfolded.

[0026] The projection screen assembly 100 further includes a first drive mechanism 150, which is used to drive the screen 110 to unfold along the unfolding direction a or to retract along the retracting direction b.

[0027] The first drive mechanism serves as the power source, directly driving the curtain 110 to move along opposite unfolding directions a and retracting directions b, providing power for the unfolding and retracting of the curtain. During the unfolding or retracting of the curtain 110, and in the fully unfolded state, the extension direction of the guide rail 120 is always parallel to the movement direction of the curtain (unfolding direction a, retracting direction b), and both sides of the curtain 110 are connected to the guide rail 120, so that the guide rail 120 can guide the movement path of the curtain 110, ensuring that the curtain 110 does not deviate from the preset direction when unfolding or retracting, and can form a stable force balance through the synchronous constraint on both sides of the curtain 110.

[0028] Therefore, the projection screen assembly 100 of this application avoids the problems of offset and skew during the opening and closing of the screen, ensuring the smoothness of the opening and closing process; and during the use of the projection screen assembly 100, the swing amplitude of the screen 110 is limited by the guide rail 120, which can prevent the screen 110 from shaking back and forth during use, thereby improving the overall reliability and stability of the projection screen and enhancing the user experience.

[0029] The third-party component 300 can be a vehicle body frame (such as a B-pillar) or a dedicated mounting bracket; the third-party component 300 can also be a wall or ceiling mounting bracket or a foldable bracket. The third-party component 300 needs to have a certain structural strength to provide a stable mounting base and swing support for the guide rail 120 through the movable connector 140, ensuring that the guide rail will not swing due to insufficient stability of the third-party component 300 when it moves with the support drive module.

[0030] In some embodiments, please refer to Figure 2 , Figure 2 This is another structural schematic diagram of the projection screen assembly in some embodiments of this application. The guide rail 120 can swing relative to the third-party component within a preset angle range, wherein, as shown... Figure 2 As shown, after the curtain 110 is rolled up, the extension direction d of the guide rail 120 intersects with the unfolding direction a and the rolling direction b of the curtain 110.

[0031] The guide rail 120 can swing relative to the third-party component 300 within a preset angle range to achieve a directional change from the unfolded state to the retracted state. Specifically, after the curtain 110 is rolled up, the extension direction d of the guide rail 120 is no longer parallel to the unfolding direction a and the retracting direction b, but instead forms an intersecting relationship through the swing of the guide rail 120 within the angle range.

[0032] Therefore, the extension direction d of the guide rail 120 after the screen 110 is rolled up intersects with the unfolding and rolling directions b of the screen 110, which can reduce the storage space occupied by the projection screen assembly 100. At the same time, the limitation of the preset angle range ensures the controllability of the swing and avoids structural interference or damage caused by excessive swing.

[0033] Please refer to the following: Figure 3 , Figure 3 The diagram below shows the structure of the support drive module in some embodiments of this application. In some embodiments, the projection screen assembly 100 further includes a support drive module 130 and a second drive mechanism 131. The support drive module 130 includes a sliding component 132. The second drive mechanism 131 is used to drive the support drive module 130 to move. One end of the sliding component 132 is connected to the output end of the second drive mechanism 131, and the other end of the sliding component 132 is fixed to the guide rail 120. The guide rail 120 is movably connected to the third-party component through a movable connector 140. When the second drive mechanism 131 drives the support drive module 130 to move, the second drive mechanism 131 drives the sliding component 132 to move. The sliding component 132 drives the guide rail 120 to swing within a preset angle range with the movable connector 140 as the fulcrum.

[0034] The support drive module 130 includes a second drive mechanism 131 and a sliding component 132. The second drive mechanism 131 serves as a power source, providing power for the swing of the guide rail 120. One end of the sliding component 132 is connected to the output end of the second drive mechanism 131, receiving the power output by the second drive mechanism 131, while the other end is fixedly connected to the guide rail 120, allowing direct power transmission to the guide rail 120. Meanwhile, the movable connector 140 serves as the swing fulcrum of the guide rail 120. One end is connected to a third-party component 300, and the other end is movably connected to the guide rail 120, providing both an installation base for the guide rail 120 and defining the swing center of the guide rail 120, preventing the guide rail 120 from deviating from the preset motion trajectory.

[0035] When the curtain 110 needs to be unfolded, the second drive mechanism 131 is activated and drives the sliding component 132 to move. The sliding component 132, through its fixed connection with the guide rail 120, causes the guide rail 120 to swing towards the unfolding direction with the movable connector 140 as the fulcrum, until the extension direction of the guide rail 120 is parallel to the unfolding direction of the curtain 110, thus meeting the guiding requirements when the curtain 110 is unfolded. When the curtain 110 needs to be rolled up, the second drive mechanism 131 is activated in the opposite direction and drives the sliding component 132 to move, thereby causing the guide rail 120 to swing towards the storage direction with the movable connector 140 as the fulcrum, ultimately causing the extension direction of the guide rail 120 to intersect with the unfolding and rolling directions of the curtain 110.

[0036] Thus, the projection screen assembly 100 of this application, through the synergistic action of the support drive module 130 and the movable connector 140, achieves automated control of the swing of the guide rail 120. Without manual adjustment, the guide rail 120 can be guided and adjusted when the screen 110 is unfolded and retracted when rolled up through the cooperation of the second drive mechanism 131 and the sliding component 132, improving the ease of operation. At the same time, the posture change of the guide rail 120 during retraction reduces the space occupied, making it suitable for various application scenarios such as vehicle-mounted and small indoor spaces, further enhancing the practicality and applicability of the projection screen assembly 100, and improving the reliability and user experience.

[0037] Please continue reading. Figure 3 In some embodiments, the sliding assembly includes a slider 133 and a sliding guide plate 134. The sliding guide plate 134 is provided with a curved groove 1341. One end of the slider 133 is connected to the output end of the second driving mechanism 131, and the other end of the slider 133 is provided with a slider (not shown). The slider is embedded in the curved groove 1341 of the sliding guide plate 134. The sliding guide plate 134 is fixed to the guide rail 120. When the second driving mechanism 131 drives the support driving module 130 to move, the slider of the slider 133 slides in the curved groove 1341 and drives the sliding guide plate 134 to move, thereby causing the guide rail 120 to swing.

[0038] The sliding component 132 includes a slider 133 and a sliding guide plate 134. One end of the slider 133 is connected to the output end of the second drive mechanism 131 and can move in a straight line under the drive of the drive mechanism. The other end of the slider is embedded in a curved groove 1341. When the slider 133 drives the slider to move in a straight line, the slider will slide along the groove wall in the curved groove 1341, and at the same time drive the sliding guide plate 134 to move. Meanwhile, the sliding guide plate 134 is fixedly connected to the guide rail 120, so that the rotation of the sliding guide plate 134 can be directly transmitted to the guide rail 120, and finally drive the guide rail 120 to swing within a preset angle range.

[0039] Thus, the sliding assembly 132, through the cooperative design of the slider 133, the sliding member, the curved groove 1341, and the sliding guide plate 134, converts the linear power of the second drive mechanism 131 into the swing power of the guide rail 120, eliminating the need for additional complex steering transmission components, simplifying the overall structure, and reducing assembly and maintenance costs. At the same time, the interlocking cooperation between the sliding member and the curved groove 1341 avoids slippage during power transmission, ensuring the stability and reliability of motion transmission. Furthermore, the arc trajectory of the curved groove 1341 can be set according to the preset swing angle of the guide rail, which can constrain the swing trajectory and amplitude of the guide rail 120, avoiding problems such as interference between the guide rail 120 and other components due to excessive swing or deviation, further ensuring the stability of the projection screen assembly 100 during automated operation.

[0040] The sliding member can be configured as a protruding structure, which is embedded in the curved groove 1341 of the sliding guide plate 134. So when the second driving mechanism 131 drives the support driving module 130 to move, the protruding structure slides in the curved groove 1341 and drives the sliding guide plate 134 to move.

[0041] In some embodiments, the curved slide 1341 is an S-shaped slide, the curvature of which matches the preset swing angle of the guide rail 120. When the slider of the slider 133 slides along the S-shaped groove, the linear motion can be smoothly converted into the swing of the guide rail 120 through the progressive thrust of the groove wall, and the S-shaped slide can avoid motion jamming.

[0042] Please refer to the following: Figure 3 and Figure 5 , Figure 5 for Figure 3 An enlarged structural diagram at point A, in some embodiments, such as Figure 2 As shown, the third-party component 300 includes a first connecting portion 310 and a second connecting portion 320. The first connecting portion 310 is located above the second connecting portion 320 in the winding direction b. The support drive module 130 also includes a support member 139. The support member 139 includes a first support member 1391. The first support member 1391 and the sliding guide plate 134 are spaced apart along the extension direction of the guide rail 120 and are located on the side of the guide rail 120 near the second connecting portion 320 of the third-party component 300. One end of the first support member 1391 is connected to the second connecting portion 320 of the third-party component 300, and the other end of the first support member 1391 is connected to the guide rail 120. Figure 5As shown, the guide rail 120 is provided with a first groove 125 adapted to the first support member 1391. The first groove 125 and the curved groove 1341 are spaced apart along the extension direction of the guide rail 120. One end of the first support member 1391 connected to the guide rail 120 is provided with a first mating member (not shown) embedded in the first groove 125. The first support member 1391 is a telescopic structure. When the guide rail 120 swings within a preset angle range, the first support member 1391 extends and retracts synchronously with the swing of the guide rail 120. The first mating member slides along the first groove 125 to adapt to the swing angle of the guide rail 120.

[0043] One end of the first support member 1391 is fixed to the second connecting part 320 of the third component 300 to ensure stable support and prevent displacement as the guide rail 120 swings. The other end of the support member 1391 is connected to the guide rail 120 through the first mating member to achieve synchronous extension and retraction of the first support member 1391 with the guide rail 120. The first groove 125 is a groove opened on the guide rail 120 according to the swing trajectory of the guide rail 120. Its length and direction match the movement requirements of the first mating member. The first mating member is embedded in the first groove 125 to prevent the connection between the first support member 1391 and the guide rail 120 from becoming loose.

[0044] Therefore, when the guide rail 120 swings within a preset angle range, the guide rail 120 will drive the first sliding groove 125 on it to rotate or move synchronously. The first mating member embedded in the first sliding groove 125 will slide along the extension direction of the first sliding groove 125 under the constraint of the groove wall. As a result, the other end of the first support member 1391 moves. When the first mating member slides towards the guide rail 120, the end of the first support member 1391 connected to the guide rail 120 is pulled, and the first support member 1391 extends. When the first mating member slides away from the guide rail 120, the end of the first support member 1391 connected to the guide rail 120 is pushed, and the first support member 1391 retracts, ultimately achieving synchronous movement of the first support member 1391 and the guide rail 120.

[0045] The first mating component can be configured as a first pin, which is embedded in the first slide groove 125, so that when the first support 1391 extends and retracts synchronously with the swing of the guide rail 120, the first pin slides along the first slide groove 125.

[0046] Please continue reading. Figure 3 and Figure 5In some embodiments, the support member 139 further includes a second support member 1392. The second support member 1392 is disposed on the side of the first support member 1391 away from the sliding guide plate 134 and located on the side of the guide rail 120 near the second connecting portion 320 of the third-party component 300. One end of the second support member 1392 is connected to the second connecting portion 320 of the third-party component 300, and the other end is connected to the guide rail 120. The guide rail 120 is provided with a second sliding groove 126 adapted to the second support member 1392. The second slide groove 126 is located on the side of the first slide groove 125 away from the curved slide groove 1341. The end of the second support member 1392 connected to the guide rail 120 is provided with a second mating member (not shown in the figure) embedded in the second slide groove 126. The second support member 1392 is a telescopic structure. When the guide rail 120 swings within a preset angle range, the second support member 1392 extends and retracts synchronously with the swing of the guide rail 120. The second mating member slides along the second slide groove 126 to adapt to the swing angle of the guide rail 120.

[0047] One end of the second support member 1392 is fixed to the second connecting part 320 of the third component 300 to ensure that it will not be displaced as the guide rail 120 swings. The other end of the support member 1392 is connected to the guide rail 120 through the second mating member to realize that the second support member 1392 extends and retracts synchronously with the guide rail 120. The second groove 126 is a groove opened on the guide rail according to the swing trajectory of the guide rail 120. Its length and direction match the movement requirements of the second mating member. The second mating member is embedded in the second groove 126 to prevent the connection between the second support member 1392 and the guide rail 120 from becoming loose.

[0048] Therefore, when the guide rail 120 swings within a preset angle range, the guide rail 120 will drive the second slide groove 126 on it to rotate or move synchronously. The second mating member embedded in the second slide groove 126 will move along the extension direction of the second slide groove 126 under the constraint of the groove wall. This will drive the end of the second support member 1392 connected to the guide rail 120 to move. When the second mating member slides towards the guide rail 120, the end of the second support member 1392 connected to the guide rail 120 is pulled, and the second support member 1392 extends. When the second mating member slides away from the guide rail 120, the end of the second support member 1392 connected to the guide rail 120 is pushed, and the second support member 1392 retracts, ultimately achieving synchronous movement of the second support member 1392 and the guide rail 120.

[0049] The second mating component can be configured as a second pin, which is embedded in the second slide groove 126, so that when the second support 1392 extends and retracts synchronously with the swing of the guide rail 120, the second pin slides along the second slide groove 126.

[0050] Please refer to the following: Figure 4 and Figure 6 , Figure 4 This is a schematic diagram of the sleeve support structure in some embodiments of this application. Figure 6 The diagram below illustrates the structure of the slide rail guide structure in some embodiments of this application. In some embodiments, the support member 139 includes a sleeve support structure 135 and / or a slide rail guide structure 136. That is, the first support member 1391 and the second support member 1392 can both be sleeve support structures 135, or the first support member 1391 and the second support member 1392 can both be slide rail guide structures 136; or the first support member 1391 is a sleeve support structure 135, and the second support member 1392 is a slide rail guide structure 136; or the first support member 1391 is a slide rail guide structure 136, and the second support member 1392 is a sleeve support structure 135. Figure 4 As shown, the sleeve support structure 135 is composed of multiple sleeve units 1351 that can be nested together. One end of the sleeve support structure 135 is connected to the third-party component 300, and the other end is connected to the guide rail 120. When the guide rail 120 swings towards the direction of curtain unfolding (as indicated by c2 in the figure), the multiple sleeve units 1351 extend outwards. When the guide rail swings away from the direction of curtain unfolding (as indicated by c1 in the figure), the multiple sleeve units 1351 nest together and retract. Figure 6 As shown, the slide rail guide structure 136 has multiple stepped, adapted guide units 1361. Adjacent guide units 1361 are provided with adapted sliding contact surfaces 1362. One end of the slide rail guide structure 136 is connected to the third-party component 300, and the other end of the slide rail guide structure 136 is connected to the guide rail 120. When the guide rail 120 swings towards the direction of the curtain unfolding (as indicated by c2 in the figure), the multiple guide units 1361 move away from each other along the sliding direction e, and the sliding contact surfaces 1362 disengage and extend. When the guide rail 120 swings away from the direction of the curtain unfolding (as indicated by c1 in the figure), the multiple guide units 1361 slide relative to each other, and the sliding contact surfaces 1362 gradually come together and contract.

[0051] The sleeve support structure 135 is composed of multiple sleeve units 1351 with successively decreasing dimensions that can be nested together to form a deformable structure. When the guide rail 120 swings along the c2 direction (closer to the curtain unfolding direction), the straight distance between the guide rail 120 and the third-party component 300 will increase accordingly. At this time, the multiple sleeve units 1351 will extend towards each other under the thrust of the increased distance, making the sleeve support structure 135 longer as a whole to accommodate the increased spacing. When the guide rail 120 swings along the c1 direction (away from the curtain unfolding direction), the spacing between the guide rail 120 and the third-party component 300 will decrease. The sleeve units 1351 will nest towards each other under the pressure of the reduced spacing, making the sleeve support structure 135 shorter as a whole, avoiding structural interference due to length redundancy.

[0052] Therefore, the sleeve support structure 135 can extend and retract synchronously with the swing of the guide rail 120, always providing stable lateral support for the guide rail 120, effectively counteracting the shaking caused by external forces during the swing of the guide rail 120, and preventing the guide rail 120 from deviating from the preset swing trajectory. Especially after the screen 110 is unfolded, it can support the guide rail 120 to maintain a posture parallel to the unfolding direction, ensuring that the screen 110 is flat and improving the stability of the projected image. At the same time, the nestable sleeve unit 1351 has a simple and reliable structure, without the need for complex transmission components. It can adapt to the spacing changes under different swing angles, and can shorten the length by nesting when the screen 110 is rolled up, reducing the storage space occupied, and is suitable for scenarios such as vehicle-mounted installations.

[0053] The number of sleeve units 1351 in the sleeve support structure 135 can be set according to the actual situation, such as... Figure 4 An example is shown where the sleeve support structure 135 can be composed of five sleeve units 1351.

[0054] The first end 1 of the sleeve support structure 135 is fixed to the third component 300, and its second end 2 is connected to the guide rail 120 through a mating part, so as to realize that the sleeve support structure 135 extends and retracts synchronously with the guide rail 120.

[0055] The slide rail guide structure 136 includes multiple guide units 1361 that can slide relative to each other and a sliding contact surface 1362. The multiple guide units 1361 adopt a splicing design and slide along a preset sliding direction e, which ensures the extensibility of the slide rail guide structure 136. Meanwhile, one end of the slide rail guide structure 136 is connected to the third-party component 300, and the other end is connected to the guide rail 120. When the guide rail 120 swings along the direction c2 (closer to the curtain unfolding direction), the straight-line distance between the guide rail 120 and the third-party component increases. Under the pull of the increased spacing, the guide units 1361 move away from each other along the sliding direction e. The sliding contact surfaces 1362 of adjacent guide units 1361 disengage, causing the slide rail guide structure 136 to extend as a whole and continuously provide guidance for the guide rail 120. When the guide rail swings along the direction indicated by c1 (away from the curtain unfolding direction), the spacing decreases, and the guide units 1361 move closer to each other under the action of thrust. The sliding contact surfaces 1362 of adjacent guide units 1361 gradually fit together, the structure contracts, and interference with other components is avoided.

[0056] Thus, the sliding guide structure 136 ensures that the guide rail 120 swings stably within a preset angle range through synchronous extension and guidance, avoiding problems such as the screen 110 tilting or interfering with other components due to trajectory deviation, further improving the smoothness of the screen 110's retraction and the stability of the projected image; at the same time, the sliding structure of its multiple guide units 1361 is simple and reliable, requiring no complex transmission components, which can adapt to the spacing changes under different swing angles, and can also retract during retraction to save space.

[0057] The number of guide units 1361 in the slide rail guide structure 136 can be set according to the actual situation, such as... Figure 6 An example is shown where the slide rail guide structure 136 can be composed of 5 guide units 1361.

[0058] The slide rail guide structure 136 has a third end 3 and a fourth end 4 arranged opposite to each other. The third end 3 of the slide rail guide structure 136 is fixed to the third third component 300, and the fourth end 4 of the slide rail guide structure is connected to the guide rail 120 through a mating part, so as to realize that the slide rail guide structure 136 extends and retracts synchronously with the guide rail 120.

[0059] Wherein, when the first support member 1391 is a sleeve support structure 135 and the second support member 1392 is a slide rail guide structure 136, when the guide rail 120 swings within a preset angle range, the guide rail 120 will drive the first slide groove 125 and the second slide groove 126 on it to rotate or move synchronously. The first mating member embedded in the first slide groove 125 will slide along the extension direction of the first slide groove 125 under the constraint of the groove wall, and the second mating member embedded in the second slide groove 126 will slide along the extension direction of the second slide groove 126 under the constraint of the groove wall; thereby driving the second end 2 of the sleeve support structure 135 and the fourth end 4 of the slide rail guide structure 136 to move. When the first mating member slides away from the first end 1... When the second mating member slides away from the third end 3, the second end 2 and the fourth end 4 are pulled, the sleeve unit 1351 extends outward, the sleeve support structure 135 extends, the guide unit 1361 moves away from each other along the sliding direction e, and the slide rail guide structure 136 extends; when the first mating member slides towards the first end 1 and the second mating member slides towards the third end 3, the second end 2 and the fourth end 4 are pushed, the sleeve unit 1351 nests with each other, the sleeve support structure 135 contracts, the multiple guide units 1361 slide closer to each other, and the slide rail guide structure 136 contracts, ultimately achieving synchronous movement of the sleeve support structure 135 and the slide rail guide structure 136 with the guide rail 120.

[0060] Please see Figure 3 In some embodiments, the support drive module 130 further includes a cover plate 138, which includes a first cover plate 1381 and a second cover plate 1382. The second cover plate 1382 is movably connected to the first connecting portion 310 of the third-party component 300. When the guide rail 120 swings at an angle closer to the unfolding direction of the curtain 110, the second cover plate 1382 is disposed between the first cover plate 1381 and the second connecting portion 320 of the third-party component 300.

[0061] The first cover plate 1381 is fixedly connected to the guide rail 120 by means such as bolts, and moves synchronously with the guide rail 120. When the guide rail 120 swings in the c2 or c1 direction, the first cover plate 1381 will rotate with the guide rail 120 to provide lateral protection for the guide rail 120 (preventing external debris from contacting the guide rail transmission components). At the same time, when the first cover plate 1381 swings with the guide rail 120, it will drive the second cover plate 1382 to adjust synchronously through the movable connection end with the second cover plate 1382. When the guide rail 120 swings towards the angle close to the unfolding direction of the curtain 110, the second cover plate 1382 is located between the first cover plate 1381 and the second connection part 320 of the third-party component 300, ensuring that the first cover plate 1381 and the second cover plate 1382 always maintain a connected state and avoid the generation of protective gaps.

[0062] Thus, by splitting the cover plate 138, the sealing and safety of the overall structure of the support drive module 130 are improved, the impact of dust and foreign objects on the internal components of the support drive module 130 is reduced, and the service life is extended.

[0063] In some embodiments, the support member 139 further includes a third support member 137, which is connected between the second cover plate 1382 and the guide rail 120. The third support member 137, the first support member 1391, and the sliding guide plate 134 are spaced apart along the extension direction of the guide rail 120. The third support member 137 is a telescopic structure, wherein when the guide rail 120 swings at an angle closer to the unfolding direction of the curtain 110 (as indicated by c2 in the figure), the third support member 137... When the third support member 137 extends, the second cover plate 1382 moves toward the guide rail 120 and away from the second connecting portion 320 of the third third component 300 as the third support member 137 extends; when the guide rail 120 swings at an angle away from the unfolding direction of the curtain 110 (as indicated by c1 in the figure), the third support member 137 retracts, and the second cover plate 1382 moves toward the second connecting portion 320 of the third third component 300 and away from the guide rail 120 as the third support member 137 retracts.

[0064] One end of the third support member 137 is connected to the second cover plate 1382, and the other end is connected to the guide rail 120. The second cover plate 1382 serves as a fixed carrier for the third support member 137, providing a stable installation foundation for the third support member 137 and preventing the connection end from shifting when it swings with the guide rail 120. At the same time, one end of the third support member 137 is connected to the cover plate 1382, and the other end is connected to the guide rail 120, ensuring that the third support member 137 can always move synchronously with the swing of the guide rail 120 and will not become disconnected from the movement of the guide rail 120.

[0065] In some embodiments, the structure of the third support member 137 may also include a sleeve support structure 135 or a slide rail guide structure 136. In some embodiments, the third support member 137 may also be configured as other retractable structures, for example, the third support member 137 may be configured as a push rod structure.

[0066] Please see Figure 7 , Figure 7 This is a schematic diagram of the push rod structure in some embodiments of this application. In some embodiments, when the third support member 137 is a push rod structure, such as... Figure 7As shown, the push rod structure includes multiple push rod units 1371 that can be nested together. When the guide rail 120 swings towards the direction of the curtain unfolding (as indicated by c2 in the figure), the multiple push rod units 1371 extend outwards. When the guide rail 120 swings away from the direction of the curtain unfolding (as indicated by c1 in the figure), the multiple push rod units 1371 nest together and retract, thereby achieving extension and retraction. This allows the push rod structure to flexibly adjust its overall length according to the change in the distance between the guide rail 120 and the cover plate 138.

[0067] Therefore, when the guide rail 120 swings towards the direction of the curtain unfolding (as indicated by c2 in the figure), the straight-line distance between the guide rail and the cover plate 138 increases accordingly. The push rod units 1371 extend towards each other under the pulling action of the increased spacing, causing the third support member 137 to extend as a whole to adapt to the increased spacing. When the guide rail 120 swings away from the direction of the curtain unfolding (as indicated by c1 in the figure), the spacing between the guide rail and the cover plate 138 decreases. The push rod units 1371 nest towards each other under the pushing action of the reduced spacing, and the third support member 137 retracts as a whole to avoid interference with other components due to length redundancy. Ultimately, the synchronous movement of the third support member 137 and the guide rail is achieved, which helps to maintain the stability of the guide rail swing process.

[0068] The number of push rod units 1371 in the push rod structure can be set according to the actual situation, such as... Figure 7 An example is shown where the push rod structure can be composed of three push rod units 1371.

[0069] In some embodiments, one end of the third support member 137 is fixed to the guide rail 120, and the other end of the third support member 137 is provided with a third mating member (not shown in the figure), such as... Figure 5 As shown, the second cover plate 1382 is provided with a third sliding groove 1383 adapted to the third mating member. The third mating member is embedded in the third sliding groove 1383. When the guide rail 120 swings within a preset angle range, the third support member 137 extends and retracts synchronously with the swing of the guide rail 120. The third mating member slides along the third sliding groove 1383 to adapt to the angle of the guide rail 120 when it swings.

[0070] In some embodiments, when the third support 137 is a push rod structure, such as Figure 7As shown, the push rod structure has a fifth end 5 and a sixth end 6 arranged opposite to each other. The fifth end 5 of the push rod structure is fixed to the guide rail 120, and the sixth end 6 of the push rod structure is provided with a third mating member. The fifth end 5 of the push rod structure is fixed to the guide rail 120 to ensure that it can swing synchronously with the guide rail 120 and will not be disengaged from the guide rail 120. Its sixth end 6 is connected to the second cover plate 1382 through the third mating member to realize that the push rod structure swings and extends synchronously with the guide rail 120. The third groove 1383 is a groove opened on the second cover plate 1382 according to the swing trajectory of the guide rail 120. Its length and direction match the movement requirements of the third mating member. The third mating member is embedded in the third groove 1383 to avoid loosening of the connection between the push rod structure and the second cover plate 1382.

[0071] Therefore, when the guide rail 120 swings within a preset angle range, the guide rail will drive the fifth end 5 of the push rod structure to swing synchronously, which in turn will drive the third mating part of the sixth end 6 to move with the guide rail. The third mating part embedded in the third groove 1383 will slide along the extension direction of the third groove 1383 under the constraint of the groove wall; thereby driving the sixth end 6 of the push rod structure to move. When the third mating part slides away from the fifth end 5, the sixth end 6 is pulled, and multiple push rod units 1371 extend outwards, and the push rod structure extends. When the third mating part slides towards the fifth end 5, the sixth end 6 is pushed, and multiple push rod units 1371 nest inwards, and the push rod structure retracts, ultimately achieving synchronous movement of the push rod structure and the guide rail 120.

[0072] The third mating component can be configured as a third pin, which is embedded in the third slide groove 1383, so that when the push rod structure extends and retracts synchronously with the swing of the guide rail 120, the third pin slides along the third slide groove 1383.

[0073] Please refer to the following: Figure 8 and Figure 9 , Figure 8 This is another structural schematic diagram of the support driving module in some embodiments of this application. Figure 9 for Figure 8 As shown in the enlarged structural diagram at point B, after the curtain 110 is rolled up, the guide rail 120 changes direction from the unfolded state to the retracted state. At this time, the first support member 1391, the second support member 1392 and the third support member 137 are all in the retracted state.

[0074] When the curtain 110 is rolled up, the extension direction of the guide rail 120 changes from being parallel to the curtain unfolding direction to intersecting with the unfolding direction a and the rolling direction b. The distance between the guide rail 120 and the third-party component 300 and the cover plate 138 also decreases accordingly. As a result, due to the reduced distance between the guide rail 120 and the third-party component 300, multiple sleeve units 1351 of the sleeve support structure 135 nest and contract. The sliding guide structure 136, along with the change in the distance between the guide rail 120 and the third-party component 300, has multiple guide units 1361 sliding closer to each other to shorten the overall length. Due to the reduced distance between the guide rail and the second cover plate 1382, the push rod units 1371 of the push rod structure nest and contract, causing the second cover plate 1382 to move closer to the first cover plate 1381, thus causing the cover plate 138 to contract to a compact state.

[0075] Therefore, when the screen 110 is rolled up, the sleeve support structure 135, the slide rail guide structure 136 and the push rod structure are simultaneously in a retracted state, which can reduce the overall space occupied by the projection screen assembly 100 and avoid occupying too much redundant space when the structure is unfolded.

[0076] Please see Figure 10 , Figure 10This is another structural schematic diagram of the projection screen assembly in some embodiments of this application. In some embodiments, the first cover plate 1381 includes a first sub-cover plate 1381A and a second sub-cover plate 1381B. The ends of the first sub-cover plate 1381A and the second sub-cover plate 1381B near the guide rail 120 are respectively fixedly connected to the guide rail 120 on both sides perpendicular to its extension direction. The first sub-cover plate 1381A and the second sub-cover plate 1381B are fixedly connected to the guide rail 120 on both sides perpendicular to its extension direction. The projection of the plane containing the extension direction of the guide rail 120 coincides with the second cover plate 1382, which includes a third sub-cover plate 1382A and a fourth sub-cover plate 1382B. The ends of the third sub-cover plate 1382A and the fourth sub-cover plate 1382B near the guide rail 120 are respectively connected to the ends of the first sub-cover plate 1381A and the second sub-cover plate 1382B away from the guide rail 120. The third sub-cover plate 1382A and the fourth sub-cover plate 1382B are respectively connected to the... The first connecting portion 310 of the third-party component 300 is movably connected, wherein the projections of the third sub-cover plate 1382A and the fourth sub-cover plate 1382B on the plane perpendicular to the extension direction of the guide rail 120 coincide, and the third sliding groove 1383 is disposed on the third sub-cover plate 1382A and the fourth sub-cover plate 1382B. When the guide rail 120 swings at an angle closer to the curtain unfolding direction (as indicated by c2 in the figure), the third support member 137 extends and drives the third sub-cover plate 1382A and the fourth sub-cover plate 1382B to move away from the second connecting portion 320 of the third-party component 300; when the guide rail 120 swings at an angle away from the curtain unfolding direction (as indicated by c1 in the figure), the third support member 137 retracts and drives the third sub-cover plate 1382A and the fourth sub-cover plate 1382B to move closer to the second connecting portion 320 of the third-party component 300.

[0077] The first cover plate 1381 is provided with a first sub-cover plate 1381A and a second sub-cover plate 1381B, both of which are fixedly connected to the guide rail 120 and can swing synchronously with the guide rail 120, respectively covering different areas of the guide rail. The third sub-cover plate 1382A and the fourth sub-cover plate 1382B of the second cover plate 1382 are in a cooperative motion relationship. The third mating part of the third support member 137 is embedded in the third sliding groove 1383 of the fourth sub-cover plate 1382B, so that the extension and retraction power of the third support member 137 can be directly transmitted to the fourth sub-cover plate 1382B. The third sub-cover plate 1382A and the fourth sub-cover plate 1382B are connected by a connecting structure to ensure that the two can move synchronously.

[0078] Therefore, when the guide rail 120 swings towards the direction of curtain unfolding (c2 direction), the third support member 137 pushes the fourth sub-cover plate 1382B through the cooperation of the third mating member and the third slide groove 1383, thereby driving the third sub-cover plate 1382A to move together towards the second connecting part 320 away from the third third component 300, so that the second cover plate 1382 unfolds as a whole, and cooperates with the first cover plate 1381 to form a larger protection range, covering the exposed parts of the support drive module 130; when the guide rail 120 swings away from the direction of curtain unfolding (c1 direction), the third support member 137 pulls the fourth sub-cover plate 1382B and the third sub-cover plate 1382A towards the second connecting part 320 near the third third component 300, and the second cover plate 1382 retracts as a whole, fitting against the first cover plate 1381, reducing space occupation.

[0079] The first sub-cover plate 1381A and the second sub-cover plate 1381B are respectively disposed on both sides of the guide rail 120 in a plane perpendicular to its extension direction, so as to protect the guide rail and the components inside the support drive module 130 from both sides. The projections of the first sub-cover plate 1381A and the second sub-cover plate 1381B in the plane perpendicular to the extension direction of the guide rail 120 coincide. That is, when viewed along a direction perpendicular to the extension direction of the guide rail 120, the outlines of the first sub-cover plate 1381A and the second sub-cover plate 1381B overlap. Similarly, the projections of the third sub-cover plate 1382A and the fourth sub-cover plate 1382B in the plane perpendicular to the extension direction of the guide rail 120 also coincide, thereby providing protection on both sides.

[0080] Please continue reading. Figure 3 In some embodiments, one end of the cover plate 138 is movably connected to the first connection portion 310 of the third-party component 300 via the movable connector 140, wherein when the second drive mechanism 131 drives the support drive module 130 to move, the cover plate 138 moves with the movable connector 140 as the fulcrum.

[0081] One end of the cover plate 138 is rotatably connected to the third-party component 300 via a movable connector 140, providing a stable mounting base for the cover plate 138 and ensuring that the swing trajectory of the cover plate 138 is coordinated with the swing trajectory of the guide rail 120. Thus, when the second drive mechanism 131 drives the support drive module 130 to move, the guide rail 120 swings within a preset angle range with the movable connector 140 as the fulcrum. Simultaneously, the cover plate 138 also moves synchronously with the same movable connector 140 as the fulcrum. When the guide rail 120 swings towards the direction of curtain unfolding (c2 direction), the cover plate 138 rotates around the movable connector 140 to unfold away from the third-party component; when the guide rail swings away from the direction of curtain unfolding (c1 direction), the cover plate 138 rotates in the opposite direction around the movable connector 140 to retract towards the third-party component 300, reducing space occupation.

[0082] In some embodiments, the movable connector 140 may be a rotating pin. The rotating pin engages with pre-set mounting holes in a third-party component, the guide rail 120, and the cover plate 138 through a through-hole configuration to achieve a movable connection. The cylindrical surface of the pin ensures smooth rotation and prevents jamming.

[0083] In addition, the diameter and length of the rotating pin are designed according to the installation thickness and force requirements of the guide rail 120 and the cover plate 138. This ensures a tight connection, reduces radial wobble during rotation, and avoids excessive installation gaps caused by size mismatch. It also ensures that the guide rail 120 and the cover plate 138 swing synchronously with the same fulcrum, maintaining the consistency of the motion trajectory.

[0084] Therefore, when the projection screen assembly 100 of this application needs to unfold the screen 110, the second drive mechanism 131 is activated, driving the sliding component 132 to move. The slider 133 moves in a straight line, and its sliding member slides in the curved groove 1341 of the sliding guide plate 134, converting the linear power into swing power, pushing the guide rail 120 to swing towards the screen unfolding direction (c2 direction) with the movable connector 140 as the fulcrum. During this process, the sleeve support structure 135 extends and stretches outwards due to the increased distance between the guide rail and the third component 300, providing lateral support for the guide rail; the guide unit 1361 of the slide rail guide structure 136 moves away from each other in the sliding direction e, constraining the swing trajectory of the guide rail 120 and preventing deviation; the third support member 137 extends synchronously, driving the second cover plate 1382 to move away from the third component 300, cooperating with the first cover plate 1381 that swings synchronously with the guide rail 120, expanding the protection range for internal components. Finally, the guide rail 120 is adjusted to a position parallel to the unfolding direction a of the curtain 110, providing stable guidance for the smooth unfolding of the curtain 110. Subsequently, the first drive mechanism drives the curtain 110 to unfold.

[0085] When the curtain 110 needs to be rolled up, the first drive mechanism drives the curtain 110 to roll up, which is guided by the guide rail 120. The second drive mechanism 131 then runs in the opposite direction, and the sliding component 132 drives the guide rail 120 to swing away from the curtain unfolding direction (c1 direction) with the movable connector 140 as the fulcrum, realizing the conversion from unfolded posture to rolled-up posture. At this time, the distance between the guide rail 120 and the third component 300 and the cover plate 138 decreases, the sleeve unit 1351 of the sleeve support structure 135 nests and contracts to avoid length redundancy; the guide unit 1361 of the slide rail guide structure 136 slides closer to each other, shortening the overall length; the third support 137 contracts, pulling the second cover plate 1382 toward the first cover plate 1381. Finally, the curtain 110 completes the roll-up, the sleeve support structure 135, the slide rail guide structure 136, and the third support 137 are all in a contracted state, and the cover plate 138 also contracts to a compact form, reducing space occupation.

[0086] Therefore, through the coordinated support of multiple structures, the screen 110 can be ensured to remain stable even under external forces. This eliminates concerns about screen 110 shaking or blurry projected images caused by external forces, thus improving the user experience.

[0087] In some embodiments, the sleeve support structure 135 and slide rail guide structure 136 connecting the guide rail 120 and the third-party component 300 in the support drive module 130 of the projection screen assembly 100 can be replaced with a chain-type connection structure. This chain-type structure consists of multiple metal chain links that can be hinged to each other. One end of the chain-type structure is fixed to the connecting seat of the third-party component 300, and the other end is connected to the guide rail 120. When the guide rail 120 swings towards the screen unfolding direction (c2 direction), the chain-type structure unfolds synchronously with the swing of the guide rail 120, adapting to the swing angle of the guide rail 120 through the hinge rotation between the chain links; when the guide rail 120 swings away from the screen unfolding direction (c1 direction), the chain-type structure naturally retracts.

[0088] Please continue reading. Figure 1 In some embodiments, the support drive module 130 includes a first support drive module 130A and a second support drive module 130B, which are respectively disposed on both sides of the curtain 110. The guide rail 120 includes a first guide rail 120A and a second guide rail 120B, which are respectively disposed on both sides of the curtain 110. The first support drive module 130A and the second support drive module 130B are used to drive the first guide rail 120A and the second guide rail 120B to swing within a preset angle range.

[0089] The symmetrical design of the support drive modules on both sides and the guide rails 120 on both sides is fixed to the edge of the screen 110, forming double-sided support and guidance to avoid screen displacement caused by force on one side.

[0090] Please see Figure 11 , Figure 11 This is another structural schematic diagram of the projection screen assembly in some embodiments of this application. In some embodiments, the first support drive module 130A and the second support drive module 130B of the projection screen assembly 100 may include at least a set of sleeve support structures 135.

[0091] Specifically, the first support drive module 130A and the second support drive module 130B are each configured with a set of sleeve support structures 135. One end of each structure is fixed to a third component 300, and the other end is connected to the corresponding side guide rail (first guide rail 120A or second guide rail 120B). In this configuration, the sleeve support structures 135 on both sides can swing and extend synchronously with the guide rail 120, forming a symmetrical lateral support force to match the balanced requirements of dual-side drive; or, only one set of sleeve support structures 135 is configured in the first support drive module 130A or the second support drive module 130B to provide support for a single side guide rail 120.

[0092] In some embodiments, the first support drive module 130A and the second support drive module 130B of the projection screen assembly 100 may include at least a set of slide rail guide structures 136.

[0093] Specifically, the first support drive module 130A and the second support drive module 130B are each configured with a set of slide rail guide structures 136. One end of each structure is fixed to the third-party component 300, and the other end is connected to the guide rail (first guide rail 120A or second guide rail 120B) on the corresponding side, and moves synchronously with the drive and support components on both sides; or, only one set of slide rail guide structures 136 is configured in the first support drive module 130A or the second support drive module 130B to provide guiding constraints for the guide rail 120 on one side.

[0094] Please see Figure 12 , Figure 12 The present invention provides a structural block diagram of a vehicle in some embodiments of the present application. In some embodiments, the vehicle 200 includes a body 210 and a projection screen assembly 100 as described in any of the foregoing embodiments, wherein the projection screen assembly 100 is connected to the body 210.

[0095] The projection screen assembly 100 is typically fixedly connected to the vehicle body 210 via pre-set connectors (such as bolts). The specific installation location can be adapted to the vehicle's space requirements, such as the B-pillar of the vehicle body 210, to ensure that the assembly will not become loose during driving.

[0096] Therefore, when the projection screen assembly 100 is rolled up, the sleeve support structure 135, the slide rail guide structure 136, and the push rod structure all retract, resulting in a compact overall size that can fit the limited installation space within the vehicle body 210 without occupying too much passenger space. Even if the vehicle 200 encounters bumps, steep roads, or sudden braking while driving, the impact force transmitted by the vehicle body 210 will be offset by the support drive module, and the screen 110 will remain flat and stable, with the projection effect consistent with that when the vehicle is stationary, meeting the user's needs for watching movies and working while driving.

[0097] In the above embodiments, the descriptions of each embodiment have their own emphasis. Parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments.

Furthermore, for those skilled in the art, based on the ideas of this application, there will be changes in specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the protection scope of the technical solution.
