Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles (UAVs), and in particular relates to an aerially spliced ​​ultra-short-throw high-definition display mechanism based on UAVs. Background Art

[0002] In recent years, drone technology has rapidly developed, and aerial displays have become a new trend in display technology. Driven by market demand and technological advancements, drones have become increasingly smaller, lighter, and more intelligent. Simultaneously, display technology has also made significant advances, particularly ultra-short-throw projection technology, which can project high-quality, large-scale 2K and 4K images at extremely short distances. These technological advances have laid a solid foundation for the realization of drone-based aerial display systems.

[0003] Currently, there are a few drone-based aerial LCD display methods that utilize drones to suspend LCD displays for aerial display. Because LCDs are relatively heavy, heavy drones are required. Furthermore, LCDs have a narrow viewing angle and display area. Drone-based aerial LED display methods, on the other hand, utilize drones to suspend LED display screens for aerial display. Similarly, because LED modules are relatively heavy, heavy drones are required, while lightweight, large-particle LEDs cannot achieve high-definition displays. Neither of these two aerial display solutions can achieve lightweight, double-sided, high-definition aerial displays. Furthermore, due to the weight limitations of the LCD and LED screens, the aerial display area is also limited. Furthermore, the angles of the LCD and LED screens cannot be adjusted during the aerial display process, impacting the display quality. Utility Model Content

[0004] The purpose of the present invention is to overcome the above problems existing in the prior art and provide an aerial splicing ultra-short-focus high-definition display mechanism based on a drone, so as to realize aerial splicing large-screen high-definition display, and the display angle is adjustable and the angle adjustment is convenient.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] An aerial splicable ultra-short-throw high-definition display mechanism based on a drone, comprising at least one drone display mechanism;

[0007] The drone display mechanism includes a drone, a bracket mounted on the drone, and an ultra-short-throw projector mounted on the bracket, wherein a projection screen is provided at the other end of the bracket;

[0012] Furthermore, the bracket is in an inverted U shape;

[0013] The closed end of the bracket is mounted on the drone, and the open end of the bracket is connected to the top of the projection screen.

[0014] Furthermore, the bracket includes an inverted U-shaped frame, both ends of the open end of the inverted U-shaped frame are bent forward to form a bent portion, and the other end of the bent portion is fixedly connected to the projection screen.

[0015] Furthermore, a projection screen installation area is formed between the open end of the U-shaped frame and the transverse frame, and the projection screen is fixedly installed in the projection screen installation area.

[0016] Furthermore, a magnetic strip is provided on the outside of the U-shaped frame.

[0017] Furthermore, magnetic strips are provided on the outside of the U-shaped frame and on the top of the horizontal frame.

[0018] Furthermore, the number of the propulsion fans is no less than two.

[0023] 3. In the present invention, a magnetic strip is installed on the outside of the screen fixing frame of the projection screen, which can be used to splice the projection screens on multiple drone display mechanisms. By splicing multiple projection screens, a larger display area can be achieved.

[0024] 4. In the present invention, a propulsion fan is used to adjust the angle of the projection screen. This adjustment method is not only safe and reliable, but also simple to operate and suitable for practical use.

[0025] 5. In the present invention, since the projection screen adopts a double-sided screen and is matched with an ultra-short-throw projector, double-sided display and double-sided viewing can be achieved.

DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0038] Currently, there are a few drone-based aerial LCD display methods that utilize drones to suspend LCD displays for aerial displays. However, due to the weight of LCDs, heavy drones are required. Furthermore, LCDs have a narrow viewing angle and display area. Drone-based aerial LED display methods, on the other hand, utilize drones to suspend LED display screens for aerial displays. Similarly, due to the weight of LED modules, heavy drones are required, and lightweight, large-particle LEDs cannot achieve high-definition displays.

[0039] The above two aerial display solutions have the following shortcomings: First, LCD and LED display screens are heavy, requiring larger drones, which increases the display cost; second, the viewing angle is small. Due to the aerial display, the existing LCD and LED display screens are at an elevation angle to the ground viewing angle, and the angle of the LCD and LED display screens cannot be adjusted, resulting in poor viewing effect; third, the display area is small. The existing LCD and LED display screens have a heavy takeoff weight, and when splicing is used to increase the display area, the overall picture is difficult to splice; fourth, they are not windproof. LCD and LED display screens are full-surface displays and are not airtight; fifth, they cannot be double-sided, and existing LCD and LED double-sided displays do not support double-sided display.

[0040] Therefore, by using an ultra-short-throw projector for projection and combining it with lightweight display materials as the projection screen, double-sided display can be achieved, the display angle can be adjusted, and the image can be spliced, thereby realizing large-area projection.

[0041] Example 1

[0042] like Figures 1 to 3 As shown, this embodiment provides an aerial splicable ultra-short-throw high-definition display mechanism based on a drone, including a drone display mechanism 100;

[0043] Specifically, the drone display mechanism 100 includes a drone 1, a bracket 3 provided on the drone 1, and an ultra-short-throw projector 2 provided on the bracket 3. A projection screen 4 is provided at the other end of the bracket 3. The projection screen 4 is used for the ultra-short-throw projector 2 to play audio and video content.

[0044] A screen fixing frame 5 is provided on the outside of the projection screen 4. The screen fixing frame 5 includes a U-shaped frame 51 and a transverse frame 52 provided at an open end of the U-shaped frame 51.

[0045] The bracket 3 is in an inverted U shape; the closed end of the bracket 3 is mounted on the drone 1, and the open end of the bracket 3 is connected to the top of the projection screen 4;

[0046] A propulsion fan is provided on one end of the bracket 3 close to the projection screen 4. Specifically, the number of the propulsion fans is not less than two;

[0047] The projection screens 4 are double-sided screens with micropores evenly distributed on the surface; specifically, the material of the projection screens 4 can be a yarn material;

[0048] The outside of the U-shaped frame 51 is provided with a magnetic strip; specifically, the outside of the U-shaped frame 51 and the top of the horizontal frame 52 can be provided with a magnetic strip;

[0049] Specifically, if Figure 1 As shown, under the drone 1 is a single splicing projection unit. The drone-based aerial splicing ultra-short-focus high-definition display mechanism is composed of a drone 1 + ultra-short-focus projection device (i.e., ultra-short-focus projector 2) + screen (i.e., projection screen 4). The ultra-short-focus projector 2 is fixed to the drone 1 through a bracket 3, and the projection screen 4 is fixed through a screen fixing frame 5 and connected to the bracket 3; the three frames corresponding to the U-shaped frame 51 are provided with magnetic edge strips (for convenience in splicing with other drone display mechanisms 100). The projection screen 4 can adopt a gauze screen or a double-sided screen with microporous holes to achieve the functions of windproof and double-sided display.

[0050] Ultra Short Throw Projector 2 and Projection Screen 4 Specifications:

[0051] Ultra-short-throw projector 2 uses a 1000lm ultra-short-throw projector, corresponding to a 100-inch screen (2.74 square meters), with an illumination of approximately 400lx, which is bright enough at night. If brightness requirements are lower, a 500lm projector can also be used. Ultra-short-throw projector 2 weighs less than 5kg, and the bracket 3 and projection screen 4 weigh approximately 2-3kg, which can be carried by a small drone 1.

[0052] The specifications of the drone 1, the ultra-short-throw projector 2, and the projection screen 4 can be adjusted according to the projection size and brightness requirements;

[0053] The drone-based aerial splicing ultra-short-throw high-definition display mechanism has a double-sided display with an ultra-large viewing angle in the air, which can realize double-sided display and a display with a viewing angle of over 180°.

[0054] Example 2

[0055] like Figures 1 to 3As shown, this embodiment provides an aerial splicing ultra-short-throw high-definition display mechanism based on a drone. The difference from Example 1 is that in this embodiment, the aerial splicing ultra-short-throw high-definition display mechanism based on a drone includes two drone display mechanisms 100. The projection screens 4 on the two drone display mechanisms 100 are spliced ​​together and arranged in parallel.

[0056] The drone-based aerial splicing ultra-short-throw high-definition display mechanism has a double-sided display with an ultra-large viewing angle in the air, which can realize double-sided display and a display with a viewing angle of over 180°.

[0057] Example 3

[0058] like Figure 1 and Figure 4 As shown, this embodiment provides an aerial splicable ultra-short-throw high-definition display mechanism based on a drone. The difference from Embodiment 1 and Embodiment 2 is that the aerial splicable ultra-short-throw high-definition display mechanism based on a drone includes multiple drone display mechanisms 100. The drone display mechanism 100 includes a drone 1 and two projection structures 101 provided on the drone 1. The two projection structures 101 are symmetrically arranged. The projection structures 101 include a bracket 3 and an ultra-short-throw projector 2 provided on the bracket 3. The other end of the bracket 3 is provided with a projection screen 4. The projection screen 4 is used for the ultra-short-throw projector 2 to play audio and video content. Among them, the bracket 3 in the upper projection structure 101 is installed on the drone 1. The projection screens 4 in the two projection structures 101 are spliced ​​with each other, that is, the bottom of the upper projection screen 4 is in close contact with the top of the lower projection screen 4, and the splicing forms a spliced ​​screen.

[0059] The splicing screens on the multiple drone display mechanisms 100 are spliced ​​together and arranged in parallel to form a multi-column arrangement;

[0060] Since the projection screens 4 on the multiple drone display mechanisms 100 are arranged in multiple columns, i.e., they are spliced ​​together to form a larger screen, this arrangement allows users to obtain good visual effects when viewing the screens from different angles. The installation is simple, the combination and installation are flexible, and the display effect is personalized.

[0061] By controlling the height and horizontal position of the drone 1, two or more drone display mechanisms 100 can be fixed together using magnetic side strips to form a large-scale display. Magnetic side strips can also be omitted when splicing, and other positioning technologies such as gyroscopes can be used to align the projection screens 4 of different drone display mechanisms 100 (slight misalignment at large scale and distance does not affect the image quality, so the accuracy requirement is not high). Multiple ultra-short-throw projectors 2 are combined using a fusion server to present a single, integrated image.

[0062] The drone-based aerial splicing ultra-short-throw high-definition display mechanism has a double-sided display with an ultra-large viewing angle in the air, which can realize double-sided display and a display with a viewing angle of over 180°.

[0063] Example 4

[0064] like Figures 1 to 2 and Figures 5 to 7 As described above, this embodiment provides an aerial splicing ultra-short-throw high-definition display mechanism based on a drone. The difference from Examples 1-3 is that in this embodiment, the bracket 3 includes an inverted U-shaped frame 31, and both ends of the open end of the inverted U-shaped frame 31 are bent forward to form a bent portion 32, and the other end of the bent portion 32 is fixedly connected to the projection screen 4;

[0065] A projection screen installation area 53 is formed between the open end of the U-shaped frame 51 and the horizontal frame 52, and the projection screen 4 is fixedly installed in the projection screen installation area 53;

[0066] In this configuration, the drone-based aerial, splicable, ultra-short-throw, high-definition display mechanism can be configured as a single-sided display, enabling the splicing of any number N*M units (i.e., drone display mechanism 100) to achieve ultra-large-scale projection displays. Specifically, because both ends of the open end of the inverted U-shaped frame 31 are bent forward to form a bend 32, the drone 1 is located behind the projection screen 4 and connected to the projection screen 4 via a thin metal bracket 3. The projection screen 4 uses a rear projection screen with microporous holes, and the audience views from the other side of the drone 1.

[0067] Example 5

[0068] This embodiment provides an aerial, ultra-short-throw high-definition display mechanism based on a drone. In this embodiment, the aerial, ultra-short-throw high-definition display mechanism based on a drone includes a plurality of drone display mechanisms 100. The projection screens 4 on the plurality of drone display mechanisms 100 are arranged in a matrix array with multiple rows and columns.

[0069] Since the projection screens 4 on the multiple drone display mechanisms 100 are arranged in a matrix array with multiple rows and columns, i.e., they are spliced ​​together to form a larger screen, this arrangement allows users to obtain good visual effects when viewing the screens from different angles. The installation is simple, the combination and installation are flexible, and the display effect is personalized.

[0070] This embodiment provides a drone-based, aerial, ultra-short-throw, high-definition display mechanism that can be spliced ​​together to form any number of N*M units (i.e., drone display mechanisms 100). Two or more drone display mechanisms 100 can be secured together using magnetic side bars to form a large-scale display.

[0071] Furthermore, magnetic side bars can be omitted during splicing, and other positioning technologies such as gyroscopes can be used to align the screens of different units. (Slight misalignment at large and long distances does not affect the image quality, so the accuracy requirement is not high.) Multiple projectors (i.e., ultra-short-throw projectors 2) are combined using a fusion server to present a single, integrated image.

[0072] Moreover, when necessary, the multi-wing adjustment of the drone can be used to adjust the tilt angle of the screen of each unit to suit the audience's perspective.

[0073] The utility model provides a drone-based aerial splicing ultra-short-throw high-definition display mechanism that applies ultra-short-throw optical projection technology and ultra-light projection screens to drones to achieve a smaller and lighter aerial display system while maintaining high-definition 2K and 4K image quality and enabling double-sided display.

[0074] The drone 1 and the ultra-short-throw display system are integrated into one embodiment, and the ultra-short-throw projector 2 is installed on the bottom of the drone 1 using a connecting device. At the same time, a narrow-framed screen is installed on the bottom of the drone at a position that matches the lens projection ratio of the ultra-short-throw projector 2. The screen frame (i.e., the screen fixing frame 5) and the screen (i.e., the projection screen 4) are both made of lightweight materials and are locked and connected to the bottom of the drone through a connecting device. After the drone takes off, the projection screen 4 and the ultra-short-throw projector 2 are directly brought into the air. After the ultra-short-throw projector 2 takes off, the projection image can be displayed in the air; the drone 1 and the ultra-short-throw projector 2 are separated into two embodiments, and the screen, connecting bracket, and body of the ultra-short-throw projector 2 are assembled into a display unit. The drone 1 is connected to the ultra-short-throw projector 2 through the bracket 3. After the drone 1 takes off, the ultra-short-throw projector 2 is suspended in the air using the bracket. The ultra-short-throw projector 2 is powered by its own battery system and starts to display the projection image in the air. In order to ensure the position of the picture in the air is adjusted, a propulsion fan is installed at the edge of the screen, and the display orientation of the projection screen 4 in the air can be adjusted by the fan thrust.

[0075] The angle of the projection screen 4 can also be adjusted through the connecting device between the drone 1 and the projection screen 4 (i.e., the bracket 3). It should be noted that the adjustment through the bracket 3 needs to be performed before the drone 1 takes off, that is, the angle of the projection screen 4 is adjusted when it is installed on the bracket 3.
