[0018] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0019] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0020] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0021] The embodiment of the present application provides a water lifting screen 100, comprising: The mounting frame 110 is provided with a mounting position; A lifting mechanism 120 is provided on both sides of the mounting frame 110; The curtain 130, one side of which is arranged on the installation position; A winding mechanism 140, on which a side of the curtain 130 away from the installation position is wound; A curtain pressing mechanism 150, wherein the curtain 130 is located between the unwinding mechanism 140 and the curtain pressing mechanism 150, and the curtain pressing mechanism 150 holds the curtain 130 against the unwinding mechanism 140; The lifting mechanism 120 is lifted and lowered to drive the mounting frame 110 to move in the direction away from the unwinding mechanism 140 along the movement direction of the lifting mechanism 120 to drive the curtain 130 to unfold, and the curtain pressing mechanism 150 provides a pre-tightening force to make the curtain 130 evenly stressed.

[0022] Please refer to Figures 1 to 4 In this embodiment, when the lifting mechanism 120 is started, the mounting frame 110 moves along the movement direction of the lifting mechanism 120 , driving the curtain 130 to unfold or retract in a direction away from the rolling mechanism 140 .

[0023] The curtain pressing mechanism 150 provides pre-tightening force for the curtain 130 during the whole process, ensuring that the curtain 130 is evenly stressed during the unfolding process, thereby preventing the curtain 130 from sagging due to gravity.

[0024] The uniformly stressed curtain 130 ensures the integrity and visual quality of the holographic image, and avoids image loss due to the curtain 130 not being fully unfolded.

[0025] The water-lifting gauze curtain 100 can quickly and accurately adjust the height of the curtain 130 to adapt to different viewing environments and needs, while enhancing the stability of use under various climate and environmental conditions.

[0026] It should be noted that the mounting frame 110 is provided with a mounting position, and the lifting mechanism 120 is arranged on both sides thereof, which is used to control the lifting of the mounting frame 110, thereby adjusting the height of the curtain 130. The lifting of the curtain 130 is more stable, which helps to solve the problem of the curtain 130 sagging. The mounting frame 110 is a truss.

[0027] One side of the curtain 130 is fixed at the installation position, and the other side is wound on the unwinding mechanism 140. The unwinding mechanism 140 allows the curtain 130 to be unfolded or retracted as needed, making the operation more flexible and adapting to different display needs.

[0028] The curtain 130 is located between the unwinding mechanism 140 and the curtain pressing mechanism 150. The function of the curtain pressing mechanism 150 is to ensure that the curtain 130 is subjected to uniform pre-tightening force when unwinding, reduce the droop or wrinkles of the curtain 130 when unfolding or retracting, and improve the consistency and quality of the visual effect. The curtain 130 is a composite fiber mesh cloth.

[0029] In at least one embodiment of the present application, the screen pressing mechanism 150 includes: A mounting plate 151, one end of which is fixed to the ground; A tensioning assembly 152, one end of which is disposed on the mounting plate 151, and the tensioning assembly 152 is disposed perpendicular to the unfolding direction of the curtain 130; The clamping wheel 153 is disposed at one end of the tensioning assembly 152 away from the mounting plate 151 .

[0030] Please refer to Figures 1 to 4 In this embodiment, when the curtain 130 needs to be unfolded or retracted, the unwinding mechanism 140 is activated, and the curtain 130 begins to be rolled up or released.

[0031] At the same time, the tensioning assembly 152 applies downward pressure to the curtain 130 through the pressure wheel 153 through the installation relationship between the tensioning assembly 152 and the mounting plate 151, which helps to control the tension of the curtain 130 and ensure that it is evenly stressed in the vertical direction.

[0032] The function of the clamping wheel 153 is to ensure that the screen 130 does not get loose when being rolled up, thereby improving the image quality and visual effect of the holographic projection.

[0033] The function of the clamping wheel 153 is to ensure the flatness of the screen 130 during display, effectively avoiding image distortion or blurring caused by wrinkles or sagging of the screen 130, thereby improving the overall visual effect of the holographic projection.

[0034] The mounting plate 151 is a base part of the screen pressing mechanism 150, and one end of the mounting plate 151 is fixed to the ground, providing a stable support base to ensure the stability and reliability of the entire screen pressing mechanism 150. The mounting plate 151 is a vertical rectangular plate.

[0035] One end of the tensioning assembly 152 is disposed on the mounting plate 151, and is disposed perpendicular to the unfolding direction of the curtain 130. Allowing the tensioning assembly 152 to apply vertical tension to the curtain 130 helps to keep the curtain 130 flat and taut, and prevents it from sagging or wrinkling when unfolded.

[0036] The pinch wheel 153 is disposed at one end of the tensioning assembly 152 away from the mounting plate 151, and plays a role of directly contacting and applying pressure to the curtain 130. Through the action of the pinch wheel 153, the curtain 130 can maintain appropriate tension during the unwinding process, thereby ensuring its flatness and stability during display. The pinch wheel 153 is a roller.

[0037] In at least one embodiment of the present application, a first through hole 151a is formed on the mounting plate 151; The tensioning assembly 152 includes: A first guide rod 1521, one end of which abuts against one side of the mounting plate 151, and the other end of which passes through the first through hole 151a and extends to the other side of the mounting plate 151, and is rotatably connected to the clamping wheel 153; The elastic member 1522 is sleeved on the first guide rod 1521 , and two ends thereof are respectively in contact with the first guide rod 1521 and the mounting plate 151 .

[0038] Please refer to Figures 1 to 4 In this embodiment, when the curtain 130 needs to be unfolded or retracted, the unwinding mechanism 140 starts to work and the curtain 130 moves accordingly.

[0039] As the curtain 130 moves, the tensioning assembly 152 applies pressure to the curtain 130 through the first guide rod 1521 and the pinch wheel 153. Because the first guide rod 1521 passes through the mounting plate 151 and is connected to the pinch wheel 153, the pinch wheel 153 is driven to rotate, so that the pinch wheel 153 can roll smoothly and pinch the curtain 130.

[0040] The presence of the elastic member 1522 ensures that even when the tension of the curtain 130 changes, the pressing force can maintain a certain consistency and stability, thereby reducing the wear or damage of the curtain 130 caused by uneven tension.

[0041] By continuous pressing, the flatness and stability of the screen 130 when displaying the holographic image is ensured, and the image is prevented from being distorted due to wrinkles or sagging of the screen 130 .

[0042] The first guide rod 1521 and the elastic member 1522 ensure that the screen pressing mechanism 150 can maintain good performance even in long-term use.

[0043] The first through hole 151 a opened on the mounting plate 151 allows the first guide rod 1521 to pass through and telescopically move along the opening direction of the first through hole 151 a.

[0044] One end of the first guide rod 1521 abuts against one side of the mounting plate 151, and the other end extends to the other side of the mounting plate 151 through the first through hole 151a, and is rotatably connected to the clamping wheel 153. The first guide rod 1521 is not only structurally connected to the clamping wheel 153, but also allows the clamping wheel 153 to rotate freely thereon, thereby providing smooth and continuous pressure during the clamping process. The first guide rod 1521 is a cylindrical rod, and the first through hole 151a is a circular through hole.

[0045] The elastic member 1522 is sleeved on the first guide rod 1521, and the two ends thereof are respectively in contact with the first guide rod 1521 and the mounting plate 151. The elastic member 1522 can provide necessary elastic force to help the clamping wheel 153 maintain a constant pressure on the curtain 130, and at the same time allow elastic adjustment within a certain range to meet the requirements of the curtain 130 under different heights and tension states. The elastic member 1522 is a spring.

[0046] In at least one embodiment of the present application, the first guide rod 1521 includes: A first abutting portion 1523 abuts against a side of the mounting plate 151 away from the pressing wheel 153; The rod portion 1524 is disposed in a direction perpendicular to the lifting direction of the lifting mechanism 120 and moves along the first through hole 151 a relative to the mounting plate 151 . The first abutting portion 1523 is disposed at one end of the rod portion 1524 .

[0047] Please refer to Figures 1 to 4 In this embodiment, when the lifting mechanism 120 is activated, causing the curtain 130 to rise or fall, the rod portion 1524 of the first guide rod 1521 will move in the first through hole 151a, allowing the pressure wheel 153 to naturally adjust its position following the tension of the curtain 130, thereby maintaining uniform pressure on the curtain 130.

[0048] The first abutment portion 1523 serves as a fixed point in this process, ensuring the stability and correct force transmission of the guide rod, and avoiding skewing or deviation during the lifting process.

[0049] The rod portion 1524 can be moved in the first through hole 151 a so that the pressure wheel 153 can adjust itself according to the tension requirement of the curtain 130 , thereby maintaining the flatness and uniform tension of the curtain 130 .

[0050] The flatness and stability of the screen 130 in the holographic projection are ensured, which optimizes the viewing experience and makes the image clearer and more vivid.

[0051] The first abutment portion 1523 is used to contact one side of the mounting plate 151, specifically the side away from the clamping wheel 153. A stable support point can be provided to ensure the stability of the guide rod during movement and a correct force transmission path. The first abutment portion 1523 is a nut.

[0052] The rod 1524 is arranged perpendicular to the direction of movement of the lifting mechanism 120, and the movement direction of the rod 1524 is consistent with that of the lifting mechanism 120, so that the lifting power can be effectively transmitted. In addition, the rod 1524 can move relative to the mounting plate 151 in the first through hole 151a, providing the necessary flexibility to adapt to the change of the tension of the curtain 130.

[0053] In at least one embodiment of the present application, the tensioning assembly 152 is divided into two groups, and the two groups of the tensioning assembly 152 are respectively located on both sides of the clamping wheel 153; The screen pressing mechanism 150 further includes: The connecting rod 154 is disposed on a side of the tensioning assembly 152 away from the mounting plate 151 . The connecting rod 154 passes through the pressing wheel 153 and is rotatably connected to the pressing wheel 153 .

[0054] Please refer to Figures 1 to 4 In this embodiment, when the curtain 130 needs to be rolled up or adjusted, the rolling mechanism 140 is activated and the curtain 130 begins to unfold or retract.

[0055] At the same time, the two sets of tensioning components 152 work, and transmit power to the pressure wheel 153 through the connecting rod 154, so as to ensure that the pressure wheel 153 can apply pressure evenly during the process of unfolding or retracting the curtain 130.

[0056] The connecting rod 154 enables the pressing wheel 153 to keep synchronous movement when the curtain 130 is adjusted, thereby reducing damage to the curtain 130 caused by uneven tension and ensuring that the curtain 130 maintains appropriate tension and flatness during the entire operation.

[0057] By adjusting the tension evenly on both sides, the screen 130 can remain flat at all times, which significantly improves the image quality of the holographic projection.

[0058] The connecting rod 154 and the pressing wheel 153 enable the pressing wheel 153 to roll smoothly, thereby reducing friction and wear on the curtain 130 and extending the service life of the curtain 130 .

[0059] The two sets of tensioning assemblies 152 are respectively located on both sides of the pressure wheel 153. The pressure force is more evenly distributed on the width of the curtain 130, which helps to prevent the curtain 130 from being too tight or loose on one side, thereby ensuring the flatness and stability of the full-width curtain 130.

[0060] The connecting rod 154 is disposed on a side of the tensioning assembly 152 away from the mounting plate 151, passes through the pinch wheel 153, and is rotatably connected to the pinch wheel 153. The connecting rod 154 is allowed to directly transmit the rotational force to the pinch wheel 153, so that the pinch wheel 153 can roll smoothly while maintaining the tension of the curtain 130, thereby reducing the wear on the curtain 130.

[0061] The connecting rod 154 has a geometric shape with vertical plates at both ends and a circular rod in the middle.

[0062] In at least one embodiment of the present application, the unwinding mechanism 140 includes: A bidirectional motor 141, a drive end of which is provided with a reel 142, and the side of the curtain 130 away from the installation position is wound on the reel 142; One end of the fixed base 143 is fixed to the ground. The bidirectional motor 141 is disposed on the fixed base 143 . The reel 142 is rotatably connected to the fixed base 143 .

[0063] Please refer to Figures 1 to 4 In this embodiment, when the curtain 130 needs to be extended or retracted, the operator or the automatic control system activates the bidirectional motor 141.

[0064] The bidirectional motor 141 selects a rotation direction as required to drive the reel 142 to rotate, thereby unfolding or retracting the curtain 130 .

[0065] The smooth rotation of the reel 142 is supported by the fixed base 143 , ensuring the smoothness of the entire process and the protection of the curtain 130 .

[0066] The use of the bidirectional motor 141 increases the flexibility of the system, and the expansion and retraction of the curtain 130 can be flexibly adjusted according to different display requirements or environmental conditions.

[0067] The smooth control of the reel 142 and the bidirectional motor 141 can reduce the wear of the screen 130 during operation and extend the service life of the screen 130 .

[0068] The bidirectional motor 141 allows the reel 142 to move in two directions, which means that the curtain 130 can be rolled out or retracted in. The drive end is provided with the reel 142 so that the rotation of the motor can be directly converted into the rotation of the reel 142.

[0069] The side of the curtain 130 away from the installation position is wound on the reel 142, and the rotation of the reel 142 is used to realize the smooth unfolding and tight retraction of the curtain 130, effectively managing the length and tension of the curtain 130. The reel 142 is a cylindrical rod.

[0070] One end of the fixed base 143 is fixed to the ground, providing a stable foundation for the entire winding and unwinding mechanism 140. The bidirectional motor 141 is arranged on the fixed base 143, ensuring the fixing and rotation stability of the motor and the reel 142.

[0071] In at least one embodiment of the present application, the centers of the reel 142 and the pressure wheel 153 are located on the same horizontal plane.

[0072] Please refer to Figures 1 to 4 In this embodiment, when the system starts the reeling mechanism 140, the reel 142 starts to rotate, driving the curtain 130 to unfold or retract along a predetermined direction.

[0073] At the same time, the pressure wheel 153 also participates in the tensioning and guiding of the curtain 130, ensuring that the curtain 130 remains flat without wrinkles or looseness during the rolling process.

[0074] Since the reel 142 and the pinch wheel 153 are on the same horizontal plane, the force applied to the curtain 130 when it is rolled up is more uniform, which reduces damage to the curtain 130 caused by uneven force and also makes the unfolding and retracting of the curtain 130 smoother.

[0075] Keeping the centers of the reel 142 and the clamping wheel 153 aligned helps ensure that the curtain 130 can maintain a good tension state at all times, which directly affects the display effect of the holographic image and improves the consistency and quality of the visual experience.

[0076] By arranging the centers of the reel 142 and the pinch wheel 153 on the same horizontal plane, the two components can maintain mechanical symmetry and balance during operation. Alignment optimizes the transmission and distribution of forces and reduces mechanical stress and wear that may be caused by misalignment between components.

[0077] In at least one embodiment of the present application, the lifting mechanism 120 includes: A lifting assembly, disposed on one side of the mounting frame 110; The auxiliary component is disposed on a side of the mounting frame 110 away from the lifting component.

[0078] In at least one embodiment of the present application, the lifting assembly includes: The first telescopic cylinder 1211 has one end fixed to the ground; A first telescopic frame 1212, one end of which is fixed to one end of the first telescopic cylinder 1211; A second telescopic pulley 1213, one end of which is fixed to the first telescopic frame 1212; A second telescopic frame 1214 is provided at one end of the second telescopic pulley 1213 away from the first telescopic frame 1212; A third telescopic oil cylinder 1215, one end of which is disposed at one end of the second telescopic frame 1214 away from the first telescopic frame 1212; A third telescopic frame 1216, one end of which is fixed to an end of the third telescopic cylinder 1215 away from the second telescopic frame 1214; A fourth telescopic pulley 1217, one end of which is disposed at one end of the third telescopic frame 1216 away from the third telescopic cylinder 1215; A fourth telescopic frame 1218, one end of which is disposed on the mounting frame 110, and the other end is fixed to the fourth telescopic pulley 1217 away from the third telescopic frame 1216; The auxiliary components include: The cylinder synchronization sensor 1221 is electrically connected to the first telescopic cylinder 1211 and the third telescopic cylinder 1215; A first guiding telescopic frame 1222, one end of which is disposed on the ground; One end of the first auxiliary telescopic frame 1223 is slidably connected to the first guiding telescopic frame 1222 , and the other end is fixed to a side of the mounting frame 110 away from the fourth telescopic frame 1218 .

[0079] Please refer to Figures 1 to 4 In this embodiment, when a lifting command is received, the first telescopic cylinder 1211 and the third telescopic cylinder 1215 are activated. The first telescopic cylinder 1211 and the third telescopic cylinder 1215 are the main power sources of the lifting mechanism 120 and are responsible for driving the movement of the entire mechanism.

[0080] The first telescopic oil cylinder 1211 begins to extend or contract, with one end fixed to the ground and the other end connected to the first telescopic frame 1212. As the first telescopic oil cylinder 1211 extends, the first telescopic frame 1212 pushes upward or pulls downward when contracting.

[0081] At the same time, the third telescopic oil cylinder 1215 also performs a similar action. Since the third telescopic oil cylinder 1215 is located at a higher position, the extension and contraction of the third telescopic oil cylinder 1215 further increases or decreases the height of the entire lifting structure.

[0082] As the first telescopic oil cylinder 1211 and the third telescopic oil cylinder 1215 move, the second telescopic pulley 1213 and the fourth telescopic pulley 1217 connected thereto begin to move. The second telescopic pulley 1213 and the fourth telescopic pulley 1217 help to smoothly transmit force and, through their connection with the corresponding telescopic frame, convert it into a more subtle height adjustment.

[0083] The second telescopic frame 1214 and the fourth telescopic frame 1218 assist in adjusting and maintaining the balance and alignment of the entire lifting mechanism 120 by connecting them to the pulleys.

[0084] The cylinder synchronization sensor 1221 in the auxiliary assembly ensures the synchronous operation of the first telescopic cylinder 1211 and the third telescopic cylinder 1215, so as to avoid imbalance caused by one side moving faster or slower than the other side during the lifting process.

[0085] The first guiding telescopic frame 1222 and the first auxiliary telescopic frame 1223 provide additional structural support to ensure that the mounting frame 110 maintains correct guidance and stability during the lifting process.

[0086] In at least one embodiment of the present application, the above-water lifting screen 100 further includes: The lifting column synchronization sensor 160 is disposed on the winding and unwinding mechanism 140 , and the lifting column synchronization sensor 160 is electrically connected to the lifting component and the auxiliary component.

[0087] Please refer to Figures 1 to 4 In this embodiment, the lifting column synchronization sensor 160 monitors the position and speed of the lifting component and the auxiliary component in real time, so that the lifting column synchronization sensor 160 can receive signals from these components.

[0088] The lifting column synchronization sensor 160 analyzes the received data and makes adjustments based on the preset synchronization standard. If any out-of-sync situation is detected, the lifting column synchronization sensor 160 will send instructions to adjust the operation of the lifting component or auxiliary component, such as adjusting the speed or changing the range of motion, to restore synchronization.

[0089] Ensures that the lifting and auxiliary components remain synchronized throughout the lifting operation. This is achieved through constant feedback and adjustments in response to the actual movement status.

[0090] The lifting column synchronization sensor 160 ensures that all relevant mechanical parts work synchronously during the entire lifting process.

[0091] By precisely synchronizing the movements of the lifting assembly and the auxiliary assembly, the curtain 130 is ensured to be smoothly deployed and retracted, thereby avoiding damage caused by uneven deployment or excessive stretching of the curtain 130, thereby improving the quality of the visual display.

[0092] It should be noted that the lifting column synchronization sensor 160 is disposed on the unwinding mechanism 140, and the lifting column synchronization sensor 160 is electrically connected to the lifting assembly and the auxiliary assembly. The lifting column synchronization sensor 160 can monitor and control the movement of the lifting assembly and the auxiliary assembly to ensure that their movements are completely synchronized.

[0093] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
