Description

Technical Field

[0001] The present invention relates to the technical field of image display equipment, and in particular to an adjustable holographic fan. Background Art

[0002] Holographic fans, also known as 3D holographic fan screens, use high-speed rotating light blades to accurately control the on / off time and brightness of each LED lamp bead in the light blades, combined with the phenomenon of visual persistence, to project three-dimensional images in the air. With the development of LED technology and image processing technology, the existing holographic fans have achieved significant performance improvements, can simulate a more realistic three-dimensional effect, can bring people a new visual experience, and have broad application prospects in industries such as entertainment, education and advertising.

[0003] However, despite the significant progress in holographic fan technology, there has been no significant improvement in the structural level. Most of them still use the initial fan-shaped design, which results in the projected image being essentially confined to one plane and unable to break away from the constraints of the two-dimensional plane. When observing, the audience can still clearly feel the difference between this effect and the real three-dimensional space. In addition, due to the limitations of the existing structural design, the performance improvement of the holographic fan can only rely on improving the output image quality, such as improving the resolution and enhancing the color performance, which makes the improvement of the visual effect have great limitations and cannot fundamentally solve the problem of the image being confined to the plane, so it is difficult to obtain a substantial improvement in the visual effect.

[0007] In a preferred embodiment, the rotating seat is cylindrical, the front part of the body is also cylindrical, and the first slip ring and the second slip ring are both annular;

[0008] Furthermore, a first guide groove extending forward and backward is formed on the side wall of the rotating seat, and a first sliding block slidably matched with the first guide groove is provided on the first sliding ring;

[0009] Furthermore, a second guide groove extending forward and backward is provided on the side wall of the rotating seat, and a second slide ring is provided with a second slider slidably matched with the second guide groove; a third guide groove matching with the second slider is provided on the body, and when the rotating seat stops rotating, the second guide groove and the third guide groove are distributed front and back and connected.

[0010] In a preferred embodiment, the number of the first light-emitting blades is equal to the number of the second light-emitting blades, and all the light-emitting blades in the first light-emitting blades and the second light-emitting blades are distributed at equal angles with the central axis of the rotating base as the center.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 , Figure 2As shown, the present embodiment discloses an adjustable holographic fan, which comprises a body 5, a rotating seat 1, a light-emitting control module, a controller and a motor device; the rotating seat 1 is rotatably connected to the front end of the body 5, and a plurality of first light-emitting blades 4 distributed at equal angles are fixed to the front end of the rotating seat 1; the first light-emitting blades 4 are internally installed with light-emitting bodies distributed along one or more straight lines, and can present different light-emitting states under the regulation of the light-emitting control module; the light-emitting control module is fixed in the rotating seat 1, and the motor device and the controller are installed and fixed in the body 5, and the motor device is used to drive the rotating seat 1 to rotate; the controller is preset with a program for processing the input image information and adjusting and controlling the components such as the motor device and the light-emitting control module; a mounting member 8 is provided at the rear end of the body 5; the above-mentioned components are all commonly used components of holographic fans in the prior art, and the above-mentioned components cooperate to substantially constitute a conventional holographic fan in the prior art, which has the function of displaying images, and the specific working principle is not repeated here;

[0032] See also Figure 4-Figure 8 As shown, the adjustable holographic fan also includes a first slip ring 11 and a second slip ring 3; the first slip ring 11 is located at the rear side of the first light-emitting blade 4, and the first slip ring 11 is slidably connected to the rotating seat 1, so that the first slip ring 11 can move forward and backward along the rotating seat 1 and cannot be separated from the rotating seat 1, and the first slip ring 11 and the rotating seat 1 cannot rotate relative to each other, and the first slip ring 11 is fixed with a first docking terminal 15 and a first combination part 12, and the first docking terminal 15 is connected to the light-emitting control module inside the rotating seat 1 through a flexible cable 16, and the flexible cable 16 has the characteristic of being bendable and deformable, so as to adapt to the front and rear position changes of the first slip ring 11; the second slip ring 3 is located at the rear side of the first slip ring 11, is sleeved on the rotating seat 1 and can slide forward and backward, and a plurality of second light-emitting blades 2 distributed at equal angles are fixed around the second slip ring 3, and the second light-emitting blades 2 are connected to the first light-emitting blades 2. The internal structure of the light blade 4 is the same. The second slip ring 3 is fixed with a second docking terminal 24 and a second combination part 22 which respectively cooperate with the first docking terminal 15 and the first combination part 12. The second docking terminal 24 is electrically connected to the second light-emitting blade 2. The rear end of the second slip ring 3 is rotatably connected with a traction seat 10. The traction seat 10 is provided with a threaded hole 21 extending forward and backward. The threaded hole 21 cooperates with a screw 9, so that the traction seat 10 can be driven to move forward and backward during the rotation of the screw 9. The screw 9 is driven by a positioning motor 20, and the positioning motor 20 is fixed on the body 5 and the working state is controlled by the controller. Based on the above structure, when the positioning motor 20 rotates, it will drive the traction seat 10 to move forward and backward through the screw 9, and the traction seat 10 will drive the second slip ring 3 to move forward and backward, so that the controller can adjust the front and rear position of the second slip ring 3.

[0033] See also Figure 5 , Figure 7 , Fig. 9 As shown, when the second slip ring 3 moves forward, the first combination part 12 and the second combination part 22 can be combined and connected, and at the same time, the first docking terminal 15 and the second docking terminal 24 are electrically connected. After that, the second slip ring 3 rotates synchronously with the rotating seat 1 and the second light-emitting blade 2 is adjusted to a light-emitting state by the light-emitting control module, that is, the first light-emitting blade 4 and the second light-emitting blade 2 will work simultaneously under the drive of the rotating seat 1;

[0034] See also Figure 5 , Figure 7 , Fig.10 As shown, when the second slip ring 3 moves backward, the first combination part 12 can be separated from the second combination part 22. At the same time, the first docking terminal 15 and the second docking terminal 24 are separated, and the first slip ring 11 can eventually move to the body 5 and disengage from the rotating seat 1. Thereafter, the second slip ring 3 does not rotate with the rotating seat 1, that is, when the rotating seat 1 rotates, it only drives the first light-emitting blade 4 to work alone.

[0035] In actual use, the adjustable holographic fan can work in two modes, specifically:

[0036] See also Figure 5 , Figure 7 , Fig. 9 As shown, one mode is to adjust the position of the second slip ring 3 on the rotating seat 1 so that the first combination part 12 is combined and connected with the second combination part 22, and the first docking terminal 15 is electrically connected with the second docking terminal 24. After that, the second slip ring 3 rotates synchronously with the rotating seat 1 and the second light-emitting blade 2 is adjusted to a light-emitting state by the light-emitting control module. Therefore, as the rotating seat 1 rotates, the first light-emitting blade 4 and the second light-emitting blade 2 will work simultaneously and display images respectively. Based on the difference in imaging positions, the images displayed by the first light-emitting blade 4 and the second light-emitting blade 2 are combined and matched to produce a more three-dimensional visual effect. For example, when the adjustable holographic fan is used to display two objects placed front and back, the first light-emitting blade 4 can be used to 4 and the second light-emitting blade 2 respectively display two objects, thereby producing a more realistic visual effect; at the same time, since the first slip ring 11 can move forward and backward, when the first combination part 12 is combined and connected with the second combination part 22, the first slip ring 11 can move forward and backward with the second slip ring 3 to ensure that the first docking terminal 15 and the second docking terminal 24 can maintain an electrically connected state. Therefore, in the process of the first light-emitting blade 4 and the second light-emitting blade 2 working together, there is no need to stop rotating. The controller can adjust the front and rear position of the second light-emitting blade 2 to further improve the visual effect, especially when displaying dynamic images, with the help of the front and rear movement of the second light-emitting blade 2, a more realistic and three-dimensional visual effect can be produced.

[0037] See also Figure 5 , Figure 7 , Fig.10 As shown, another mode is to adjust the position of the second slip ring 3 to move it backward, so that the first combination part 12 is separated from the second combination part 22, and at the same time, the first docking terminal 15 and the second docking terminal 24 are separated, and finally the second slip ring 3 is moved from the rear end of the rotating seat 1 to the body 5, and then the second slip ring 3 does not rotate with the rotating seat 1. Therefore, when the rotating seat 1 rotates, only the first light-emitting blade 4 rotates and works. In this mode, the adjustable holographic fan can be used as an ordinary holographic fan, and the working principle is similar to that of a traditional holographic fan. When working in this mode, the second slip ring 3 and the second light-emitting blade 2 are both in a stationary state, which can reduce the operating energy consumption of the adjustable holographic fan and avoid unnecessary mechanical wear.

[0038] like Fig. 9 As shown, in the adjustable holographic fan, since the second light-emitting blade 2 is driven by the rotating seat 1 when displaying the image, and the second light-emitting blade 2 and the rotating seat 1 will not produce rotational displacement, the second light-emitting blade 2 and the first light-emitting blade 4 can realize image display based on the same control system, and there is no need to separately set up angle sensors, light-emitting control modules and controllers for the second light-emitting blade 2, which helps to reduce the cost of the adjustable holographic fan and also helps to improve the compactness of the overall structure.

[0039] So far, the specific technical solution of the adjustable holographic fan in this embodiment has been fully and sufficiently described. There are no technical obstacles to the implementation of the technical solution using the existing technology in this technical field, and there are a variety of specific implementation structures. In order to optimize the performance of the adjustable holographic fan, the following optional technical features are also included:

The first guide groove 14 cooperates with the first slider 17 to provide guidance and limiting functions for the first slip ring 11, thereby enabling the first slip ring 11 to slide forward and backward along the rotating seat 1, and the two cannot rotate relative to each other and cannot be separated; the side wall of the rotating seat 1 is provided with a second guide groove 18 extending forward and backward, and the second slip ring 3 is provided with a second slider 23 that slidably cooperates with the second guide groove 18, and the second guide groove 18 cooperates with the second slider 23. The slider 23 can provide guidance and limiting functions for the second slip ring 3, so that when the second slip ring 3 is located on the rotating seat 1, the second slip ring 3 can slide back and forth along the rotating seat 1 and the two cannot rotate relative to each other; the body 5 is provided with a third guide groove 19 that cooperates with the second slider 23. When the rotating seat 1 stops rotating, the second guide groove 18 and the third guide groove 19 are distributed front to back and connected. Therefore, when the second slip ring 3 slides backward, it can move from the rear end of the rotating seat 1 to the body 5; in the prior art of the holographic fan, an angle sensing function is integrated in the controller. Thanks to this technical feature, the technical requirement that the second guide groove 18 and the third guide groove 19 are connected when the rotating seat 1 stops rotating can be easily achieved.

When the second slip ring 3 moves forward, it will drive the first slip ring 11 to move forward synchronously. When the first slip ring 11 cannot move forward any further, the second slip ring 3 continues to move forward to drive the first butt terminal 15 and the second butt terminal 24 to achieve plug-in matching; conversely, when the second slip ring 3 moves backward, it will drive the first slip ring 11 to move backward synchronously. When the first slip ring 11 cannot move backward any further, the second slip ring 3 continues to move backward to drive the first butt terminal 15 to separate from the second butt terminal 24.

[0043] Preferably, Figure 5 , Figure 7As shown, the first combination part 12 and the second combination part 22 are magnetic blocks respectively installed and fixed on the first slip ring 11 and the second slip ring 3, so that when the second slip ring 3 moves forward and approaches the first slip ring 11, the two magnetic blocks will be adsorbed together to realize the combined connection of the first combination part 12 and the second combination part 22; when the first combination part 12 and the second combination part 22 are in the combined state, when the second slip ring 3 moves backward, the first slip ring 11 moves backward synchronously with the second slip ring 3, and when the first slip ring 11 can no longer move backward, the second slip ring 3 continues to move backward to drive the first combination part 12 and the second combination part 22 to separate.

[0044] Preferably, Figure 7 , Figure 8 As shown, the traction seat 10 is rotatably connected to the second slip ring 3 via a bearing 13 , the outer ring of the bearing 13 is fixedly connected to the traction seat 10 , and the inner ring of the bearing 13 is fixedly connected to the second slip ring 3 .
