Description

Technical Field

[0001] This invention relates to the field of projection imaging products, and more specifically to a movable structure and a movable method for projection imaging. Background Technology

[0002] Existing projection imaging solutions or fog screen imaging are all immobile, and even if they are movable, they are structurally bulky. Therefore, the interaction between projected images and people can only be static or presented in a very rigid manner. With the progress of society, the shortcomings of their single function have become obvious.

[0003] In the prior art, CN218159579U discloses a multifunctional fog imaging external display structure, including a fog-making structure. The features are: the nozzle structure includes a shaping fog channel, an air duct structure, a shaping structure, and a nozzle opening; the nozzle opening is connected to the fog outlet end of the shaping fog channel; air duct structures are located on both sides of the shaping fog channel; the shaping structure is located inside the nozzle opening of the nozzle structure; the shaping fog channel is connected to a fog guide pipe; a projection structure is provided on one side of the fog-making structure, and the projection structure's illumination angle intersects with the nozzle structure's spray angle to create an image.

[0004] The aforementioned existing technology has the following drawbacks: the fog screen formed by the nozzle structure cannot move flexibly, and the structure is relatively cumbersome.

[0005] For example, in the prior art, CN112664778B describes a multimedia teaching projection device for interior design, characterized by a blackboard; a hidden screen is provided on the back of the blackboard, and a vertical sliding seat A is installed on one side of the blackboard; a lifting mechanism is installed on the sliding seat A, and a support rod is installed on the lifting mechanism; a sliding seat B is installed on the support rod; a telescopic rod is installed on the sliding seat B, and a placement frame is installed at the bottom of the telescopic rod. The sliding seat A on the blackboard serves as a limit stop for the sliding of the lifting block; the lifting mechanism on the sliding seat A drives the projector to rise and fall; the telescopic rod on the sliding seat B adjusts the distance between the projector and the blackboard; and a rotatably connected mounting block is provided on the telescopic rod, which adjusts the rotation position of the projector.

[0006] The aforementioned existing technology has the following drawbacks: the projector can only move within a two-dimensional plane, resulting in a small range of motion. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the prior art, the present invention provides a moving structure and a moving method for projection imaging.

[0008] A movable structure for projection imaging includes a movable component and an imaging component, characterized in that the movable component includes a fixed frame and a rotating arm assembly, the fixed frame is connected to the rotating arm assembly, the imaging component includes a projection structure and an imaging screen structure, the projection structure is disposed on the movable component, and the movable component is further provided with an imaging screen structure that crosses the projection structure to form an imaging medium, the nozzle structure of the imaging screen structure generates an imaging medium outward. The rotating arm assembly includes a first rotating arm, which includes a first rotating base and a first fixed arm. The first rotating base is connected to a fixed frame above and rotatably connected to the first fixed arm below.

[0009] The above-described movable structure for projection imaging is characterized in that when the rotating arm assembly is further provided with a second rotating arm, the second rotating arm includes a second rotating seat and a second fixed arm, the second rotating seat and the second fixed arm are rotatably connected, and when there is a second rotating arm, the second rotating seat is connected to the first fixed arm; When there are multiple second rotating arms, the second rotating seat of the uppermost second rotating arm is connected to the first fixed arm, and the second fixed arm of the previous second rotating arm is rotatably connected to the second rotating seat of the next second rotating arm.

[0010] The rotating arm assembly is a first rotating arm when it is a single unit, and can be connected to several second rotating arms when there are multiple units. The several second fixed arms are connected in series through corresponding second rotating seats. There are many ways to connect them, such as connecting them end to end or connecting them by folding them up and down.

[0011] The aforementioned movable structure for projection imaging is characterized in that the imaging screen structure is located on the lowest second fixed arm, and the projection structure is located on the rotating arm assembly at the corresponding position where it intersects with the projection screen.

[0012] The fixed arm is long and narrow. When the imaging screen structure and the projection mechanism are located on the same fixed arm, the imaging effect between the projection structure and the imaging screen structure will not be affected by the movement of the rotating arm assembly, thus preventing projection angle distortion.

[0014] The rotating base is located at the front-middle position above the fixed arm, which optimizes the weight balance at both ends of the fixed arm. The parallel rotational trajectories of the upper and lower fixed arms allow for better overlap and repositioning of the upper and lower structures.

[0015] The aforementioned movable structure for projection imaging is characterized in that the imaging screen structure has a nozzle structure comprising a mist outlet structure, an air outlet structure, and a shaping structure, with air outlet structures on both sides of the mist outlet structure, and the outlets of the mist outlet structure and the air outlet structure connected to the shaping structure.

[0016] The nozzle structure has a mist outlet structure in the middle to generate and spray mist. Since there are fans in the air outlet structures on both sides, the airflow on both sides creates a wind wall effect on the mist in the middle, and together they enter the shaping structure and spray out a uniform and flat mist curtain.

[0017] The aforementioned movable structure for projection imaging is characterized in that the imaging component further includes a telescopic pipe and a conveying structure, the conveying structure being connected to the imaging screen structure via the telescopic pipe, the telescopic pipe being disposed within the rotating arm assembly, and the conveying structure being fixed to the movable component on the side away from the nozzle structure.

[0018] The separation and fixing can reduce the weight and size of the nozzle structure. The conveying structure includes a water tank that delivers water to the mist structure through a telescopic pipe, or it includes a mist-making structure that delivers mist to the mist structure through a telescopic mist pipe. The conveying structure is not fixed to the second fixed arm where the nozzle structure is located.

[0019] The aforementioned movable structure for projection imaging is characterized in that the imaging screen structure further includes a duct and a fan structure, the duct and fan structure being located within the second fixed arm where the imaging screen structure is located, and the fan structure being connected to the air outlet structures on both sides of the nozzle structure via the duct. The imaging screen structure also includes a water return structure, which includes a semiconductor cooling chip, a heat sink, and a condenser. The heat dissipation surface of the semiconductor cooling chip is connected to the heat sink, which is located inside the air duct or the air outlet structure. The other side of the semiconductor cooling chip is connected to the condenser, and the fogging medium generated by the condenser flows into the conveying structure.

[0020] The aforementioned movable structure for projection imaging is characterized in that the movable component further includes a movable seat, which is disposed between the fixed frame and the rotating arm assembly, the movable seat is slidably connected to the fixed frame, and the movable seat is connected to the first rotating seat; or the movable component further includes a second movable seat, which is disposed between the first rotating seat and the first fixed arm, the second movable seat is rotatably connected to the fixed frame, and the second movable seat is slidably connected to the first fixed arm.

[0021] The aforementioned movable structure for projection imaging is characterized in that a rotating motor is provided in the first rotating seat and the second rotating seat, the rotating motor drives the first fixed arm to rotate around the first rotating seat, the rotating motor drives the second fixed arm to rotate around the second rotating seat, and a movable motor is provided in the movable seat, the movable motor drives the movable seat to slide with the fixed frame, or the second movable seat to slide relative to the first fixed arm.

[0022] A method for moving objects in projection imaging, characterized by employing the aforementioned moving structure for projection imaging, wherein the rotating arm assembly (12) is equipped with sensors and a camera, and also includes a control system, the specific steps of which include: Step 01: Start the machine by energizing the moving motor and the rotating motor; Step 02: The camera captures the face through facial recognition or senses the position of the human body through sensors. Through scene position analysis, it transmits key data such as the coordinates of the recognized face to the control system. The information processing calculates the distance between the imaging screen structure and the human body, as well as the angle between the imaging screen structure's imaging surface and the face. Step 03: Based on the distance and angle information in step (02), the control system transmits the running step direction to the moving motor and rotating motor to rotate, so that the imaging surface of the imaging screen structure faces the face at a suitable distance and angle.

[0023] Therefore, the present invention has the advantages of simple and flexible structure, wide range and angle of imaging activities such as mobile projection fog screen, and water recyclability. Attached Figure Description

[0034] Example 1: As Figure 1 and Figure 2 As shown, a movable structure for projection imaging includes a movable component 1 and an imaging component 2. The movable component 1 includes a fixed frame 11 and a rotating arm assembly 12. The fixed frame 11 is connected to the rotating arm assembly 12 and is used for external fixation. The rotating arm assembly 12 includes a first rotating arm 121, which includes a first rotating base 123 and a first fixed arm 124. The fixed frame 11 is connected above the first rotating base 123. A rotating motor is provided inside the first rotating base 123, and the rotating motor drives the fixed arm 124 to rotate around the first rotating base 123 via gears and a gear plate. The rotating arm assembly 12 is further provided with a second rotating arm 122. The second rotating arm 122 includes a second rotating seat 125 and a second fixed arm 126. The second rotating seat 125 and the second fixed arm 126 are rotatably connected. The second rotating seat 125 is connected to the first fixed arm 124. A rotating motor is provided in the second rotating seat 125. The rotating motor drives the gear to drive the second fixed arm 126 to rotate around the second rotating seat 125 as the center. The imaging component 2 includes a projection structure 21 and an imaging screen structure 22. The projection structure 21 and the imaging screen structure 22 are located at the left and right ends of the second fixed arm 126. The nozzle structure of the imaging screen structure 22 is a structure that can generate a projection medium. It can spray mist or similar imaging medium downwards to form a screen, thereby projecting and intersecting with the projection structure 21 to generate an image.

[0035] Alternatively, in the above embodiments, the imaging screen structure 22 can also be a telescopic screen that can extend downwards to form a projection screen when in use.

[0036] like Figure 5 The nozzle structure of the imaging screen structure 22 shown includes a mist outlet structure 226, an air outlet structure 227, and a shaping structure 228. The mist outlet structure 226 is located in the middle of the nozzle structure 221 and is used to generate and spray mist. The air outlet structure 227 is located on both sides of the mist outlet structure 226. The air outlet structure 227 is equipped with a fan, which creates a wind wall effect on the mist in the middle. The outlets of the mist outlet structure 226 and the air outlet structure 227 are connected to the shaping structure 228, so that it can spray a uniform and flat mist screen downwards. The mist screen can form a virtual imaging effect in the air. The imaging assembly (2) also includes a telescopic pipe 222 and a conveying structure 223. The conveying structure 223 is connected to the nozzle structure through the telescopic pipe 222. The telescopic pipe 222 is located inside the rotating arm assembly 12 and is connected to the conveying structure 223 at the other end of the first fixed arm 124. The conveying structure 223 includes a fogging structure and a water tank that conveys fog to the nozzle structure through the telescopic pipe 222. The separation and fixing can reduce the weight and size of the imaging screen structure 22 and be used as a counterweight for the rotating arm assembly 12.

[0037] Example 2: As Figure 3 and Figure 4 As shown, a movable structure for projection imaging includes a fixed frame 11 consisting of fixed feet 111 and a fixed frame body 114. The fixed frame 111 is positioned above the fixed frame body 114 for fixation. The fixed frame 114 is an elongated structure with a first track 112 along its length. The movable structure 1 also includes a movable seat 13, which is located between the fixed frame 11 and the first rotating arm 121. The movable seat 13 is slidably connected to the first track 112. A movable motor is installed within the movable assembly 1, which drives the movable seat 13 to move along the first track 112 on the fixed frame 11 via a gear plate and a conveyor belt. The rotating arm assembly 12 is connected below the movable seat 13.

[0038] The rotating arm assembly 12 includes a first rotating arm 121, which includes a first rotating seat 123 and a first fixed arm 124. The first rotating seat 123 is connected to a movable seat 13 above and rotatably connected to the first fixed arm 124 below. A servo motor is provided inside the first rotating seat 123, which drives the fixed arm 124 to rotate around the first rotating seat 123.

[0039] The rotating arm assembly 12 is further provided with a second rotating arm 122. The second rotating arm 122 includes a second rotating seat 125 and a second fixed arm 126. The second rotating seat 125 and the second fixed arm 126 are rotatably connected. The second rotating seat 125 is connected to the first fixed arm 124. A servo motor is provided in the second rotating seat 125. The servo motor drives the second fixed arm 126 to rotate around the second rotating seat 125 as the center. like Figure 4 As shown, when the rotating arm assembly 12 includes multiple second rotating arms 122, the lower part of the second fixed arm 126 of the previous second rotating arm 122 is rotatably connected to the upper part of the second rotating seat 125 of the next second rotating arm 122, and the upper part of the second rotating seat 125 of the uppermost second rotating arm 122 is connected to the lower part of the first fixed arm 124. The rotating arms are connected end to end through rotating seats. The imaging screen structure 22 is located in the lowermost second fixed arm 126, and the projection structure (21) is located on the first fixed arm 124 at the corresponding position of its cross imaging. The projection structure 21 is equipped with a gimbal that can rotate. When the lowermost second fixed arm 126 drives the imaging screen structure 22 to rotate to the projection position of the projection structure 21 for cross imaging.

[0040] like Figure 5 The imaging component 2 also includes a telescopic pipe 222 and a conveying structure 223. The conveying structure 223 is connected to the nozzle structure through the telescopic pipe 222. The telescopic pipe 222 is located inside the fixed arm and passes through the rotating seat to connect with the conveying structure 223 at the other end of the first fixed arm. The conveying structure 223 includes a water tank that conveys water to the nozzle structure through the telescopic pipe 222.

[0041] like Figure 6 The imaging screen structure 22 shown also includes a duct 224, a fan structure 225, and a water return structure. The duct 224 and the fan structure 225 are located within the second fixed arm 126 where the imaging screen structure 22 is located. The fan structure 225 is connected to the two side air outlet structures 227 within the nozzle structure via the duct 224. The water return structure includes a semiconductor refrigeration unit, a radiator 230, and a condenser plate. The heat dissipation surface of the semiconductor refrigeration unit is connected to the radiator 230, which is located within the duct 224. A temperature difference is formed through air cooling, causing the other side of the semiconductor refrigeration unit to connect to the condenser plate, resulting in water flowing into the conveying structure 223. The water return structure ensures that the imaging screen structure 22 can replenish water itself and collect water flowing into the conveying structure 223, forming a continuous water supply to the fog structure 226 to generate fog and form a fog screen for projection imaging.

[0042] As mentioned above, when connecting the air duct 224 and the fan structure 225, the air outlet structure 227 in the nozzle structure does not need to be equipped with a fan.

[0043] Example 3: As Figure 5, Figure 6 As shown, and refer to Figure 7 As shown: The fixing frame 11 consists of fixing feet 111 and fixing frame body 114. The fixing feet 111 are located above the fixing frame body 114 and have limiting positioning slots 113. The length of the fixing feet 111 can be positioned and adjusted so that the fixing frame 11 can be kept in a horizontal state. The fixing frame body 114 is a long strip structure. Two first tracks 112 are provided on both sides of the fixing frame body 114 along the length direction. The moving structure 1 also includes a moving seat 13. The moving seat 13 is provided with a slider to connect the first tracks 112 on both sides. The double track structure can make the moving seat 13 more firmly connected to the first tracks on both sides of the fixing frame 11. The moving seat 13 is provided with a moving motor. The moving motor drives the moving seat 13 to move along the first tracks 112 on the fixing frame body 114 through gears and racks. The rotating arm assembly 12 is connected to the lower part of the moving seat 13. The rotating arm assembly 12 includes a first rotating arm 121 and a second rotating arm 122. The first rotating arm 121 includes a first rotating base 123 and a first fixed arm 124. The upper part of the first rotating base 123 is connected to the lower part of the movable base 13, and the lower part of the first rotating base 123 is rotatably connected to the upper part of the front position of the first fixed arm 124. The lower part of one end of the first fixed arm 124 is connected to the upper part of the second rotating base 125, and the lower part of the second rotating base 125 is connected to the upper part of the front position of the second fixed arm. This structure can optimize the weight balance between the two ends of the rotating base and the fixed arm.

[0044] As described Figure 5 The fixed arm is long and narrow, and its extended state rotates to the position shown in the image. Figure 6 In the retracted state, the rotation trajectory plane of the first fixed arm 124 and the lower second fixed arm 126 is parallel. A gap exists between the upper first fixed arm and the lower second fixed arm, allowing for rotation back to overlap. A groove is provided on the first fixed arm 124 above the nozzle structure of the second fixed arm 126. This groove facilitates the embedding of the nozzle structure of the imaging screen structure 22 into the groove. The overlap of the upper and lower fixed arms after rotation and the groove design reduce the overall shape of the rotating arm assembly and protect the nozzle structure during retraction.

[0045] The imaging screen structure 21 and the projection structure 22 are located at both ends of the same second fixed arm 124 and project images crosswise. At the same time, the rotating arm assembly 12 can rotate and move at will without affecting its imaging effect.

[0046] Example 4: Figure 7 Similarly, the movable seat 13 is slidably connected to the rotating arm assembly 12. When the rotating arm assembly 12 is only the first rotating arm 121, the first rotating arm 121 includes a rotating seat 123 and a first fixed arm 124. The projection structure 21 and the imaging screen structure 22 are located at both ends of the first fixed arm 124 for cross imaging.

[0047] The rotating base 123 also includes a lifting structure, which comprises a rotary motor that drives the first fixed arm 124 to move up and down via a gear and rack. Therefore, the first fixed arm 124 can also move at any angle and project an image.

[0048] Example 5: Figure 8 As shown, a movable structure for projection imaging includes a movable component 1 and an imaging component 2. The movable component 1 includes a fixed frame 11 and a rotating arm assembly 12. The fixed frame 11 is connected to the rotating arm assembly 12. The movable component 1 also includes a second movable seat 14. A rotating seat 123 is disposed between the second movable seat 14 and a first fixed arm 124. A second track 15 is provided on the first fixed arm 124. The second movable seat 14 is slidably connected to the first fixed arm 124 via the second track 15. A movable motor drives the first fixed arm 124 to move back and forth with the second movable seat 14 as a fixed point via gears and a rack.

[0049] The rotating arm assembly 12 includes a first rotating arm 121, which includes a first rotating seat 123 and a first fixed arm 124. The first rotating seat 123 is connected to the fixed frame 11, and the second movable seat 14 is connected to the first rotating seat 123. A motor is provided inside the first rotating seat 123, and the motor drives the fixed arm 124 to rotate around the first rotating seat 123 through gears and a gear plate. In this application, the rotating arm assembly 12 can slide along the first track 112 to allow the fog screen to move horizontally. The slot limiting structure of the fixed foot 111 facilitates the adjustment of the height of the fixed body 114 and makes installation convenient. The first rotating arm 121, the second rotating arm 122, the first rotating seat 123, the first fixed arm 124, the second rotating seat 125, and the second fixed arm 126 can expand the range of motion of the projection imaging, make it more convenient to use, and improve the display effect. The water return structure can make the water used to generate the fog screen circulate, saving water resources. The first fixed arm 124 and the second fixed arm 126, and adjacent second fixed arms 126 can rotate, retract, and reset into an overlapping structure, reducing the space occupied by this application. There are many ways to connect the first rotating arm 121 and the second rotating arm 122, and the two second rotating arms 122, such as connecting end to end or connecting one end to the middle. The nozzle structure 221 and the conveying structure 223 are fixed separately, which can reduce the weight and size of the nozzle structure 221 and use it as a counterweight for the rotating arm.

[0050] Example 6: A method for moving objects in projection imaging, characterized by employing the moving structure for projection imaging described above, wherein the rotating arm assembly (12) is equipped with sensors and a camera, and also includes a control system, the specific steps of which include: Step 01: Start the machine by energizing the moving motor and the rotating motor; Step 02: The camera captures the face through facial recognition or senses the position of the human body through sensors. Through scene position analysis, it transmits key data such as the coordinates of the recognized face to the control system. The information processing calculates the distance between the imaging screen structure and the human body, as well as the angle between the imaging screen structure's imaging surface and the face. Step 03: Based on the distance and angle information in step (02), the control system transmits the running step direction to the moving motor and rotating motor to rotate, so that the imaging surface of the imaging screen structure faces the face at a suitable distance and angle.

[0051] like Figure 9 As shown, the imaging screen structure 22 adjusts its angle to follow the movement of the viewer's gaze, from state 1 to 3, thereby enabling the projected image to interact with the viewer and connecting to a controller to control the motor to move the fixed arm to a designated position.

[0052] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.

8. A method for moving objects in projection imaging, characterized in that, The movable structure for projection imaging as described in claim 7 is adopted, wherein the rotating arm assembly (12) is provided with sensors and a camera, and a control system is also provided. The specific steps include: Step 01: Start the machine by energizing the moving motor and the rotating motor; Step 02: The camera captures the face through facial recognition or senses the position of the human body through sensors. The key data of the recognized face coordinates are transmitted to the control system through scene position analysis. The information processing calculates the distance between the imaging screen structure and the human body, as well as the angle between the imaging screen structure's imaging surface and the human face. Step 03: Based on the distance and angle information obtained in Step 02, the control system transmits the number of steps and direction commands to the moving motor and the rotating motor, driving the rotating arm assembly to perform three-dimensional spatial movement, causing the physical displacement of the imaging screen structure, so that the imaging surface of the imaging screen structure faces the face at a suitable distance and angle.
