Description

Technical Field

[0001] This utility model relates to the field of advertising display applications, and in particular to a medium-free holographic advertising display device. Background Technology

[0002] With the development of advertising technology, current advertising display methods are already familiar to users. They are basically displayed through display screens or projectors. Regardless of the content, the display methods are relatively common, making it difficult to arouse user interest. For example, display screens are always a certain distance from users, so users cannot directly touch the advertising image; projection requires projection onto a specific area (such as the ground, wall, screen, etc.), and users can only view the advertising content on that specific plane and cannot interact with the advertising content itself.

[0003] Therefore, a new way of displaying advertisements is needed to improve the effectiveness of advertising. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a medium-free holographic advertising display device, which aims to solve the technical problems of traditional lightbox advertising in the prior art, such as the inability to achieve 3D projection, serious light pollution, high energy consumption, and the risk of falling off when directly fixed to the target area.

[0005] The technical solution of this utility model is: a medium-free holographic advertising display device, including a medium-free holographic advertising module and an installation component. The medium-free holographic advertising module is used to form a medium-free holographic advertising image for medium-free holographic advertising display, and to switch the image according to external actions. The installation component is used to fix the medium-free holographic advertising module to the target area.

[0006] Furthermore, the medium-free holographic advertising module of this utility model includes an image source component and a medium-free holographic waveguide plate. The image source component is used to generate the original advertising image, and the medium-free holographic waveguide plate is used to convert the original advertising image into a medium-free holographic advertising image.

[0007] Furthermore, the medium-free holographic advertising module of this utility model also includes a sensing element and a control element. The sensing element is used to sense external actions, and the control element controls the image source element to switch images based on the sensing results of the sensing element.

[0008] Furthermore, the installation assembly of this utility model includes a main positioning frame, an inner support plate, and an outer fixing frame. The main positioning frame is installed in the target area, the inner support plate is placed inside the main positioning frame, the media-free holographic advertising module is placed on the inner support plate, and the outer fixing frame is inserted into the main positioning frame and magnetically attracted to the main positioning frame. The main positioning frame is embedded in the target area, and the outermost surface of the main positioning frame is parallel to the surface of the target area.

[0009] Furthermore, the main positioning frame of this utility model includes two vertical rods spaced apart, a first horizontal bar is provided between the top and bottom ends of the two vertical rods, and a second horizontal bar perpendicular to the first horizontal bar is provided at the top and bottom ends of the two vertical rods. The other end of the four second horizontal bars is provided with an outer frame, and the outer frame is provided with multiple fixing holes. The bottom surface inside the outer frame is provided with multiple insertion holes.

[0010] Furthermore, in this utility model, the outer frame covers the outside of the opening in the target area, and the upper and lower edges of the outer frame are provided with a plurality of spaced fixing holes.

[0011] Furthermore, in this invention, the bottom of the two second crossbars at the bottom is also provided with a plurality of spaced rollers.

[0012] Furthermore, in this utility model, the corner of the inner support plate has notches that respectively cooperate with the two vertical rods, and the bottom surface of the inner support plate is in contact with the first horizontal rod and the second horizontal rod at the bottom.

[0013] Furthermore, the outer fixing plate frame of this utility model includes a fixing frame body and a connecting edge located on one side of the top of the fixing frame body. The bottom of the fixing frame body is provided with a plurality of insert posts corresponding to each of the insert holes. Locking holes are provided on both sides of the fixing frame body. The fixing frame body is inserted into the outer frame of the main positioning frame through the insert posts. The connecting edge overlaps the outer surface of the outer frame of the main positioning frame. An opening is opened in the middle of the fixing frame body.

[0014] Furthermore, in this utility model, the inner side of the connecting edge is provided with a magnetic suction member, which is disposed on the inner side of the connecting edge or embedded in the inner side of the connecting edge, and the entire outer frame or at least the upper edge is made of magnetic material.

[0015] Compared with the prior art, this utility model has the following advantages: Firstly, the combination of the main positioning frame, inner support plate, and outer fixing frame allows the medium-free holographic advertising module to be embedded and installed within the target area, ensuring stable installation and avoiding the risk of detachment associated with direct fixing to the target area. Secondly, this utility model uses a medium-free holographic advertising module to replace the traditional lightbox, forming a medium-free holographic advertising image. This eliminates the need for an internal light source, reducing energy consumption, and avoids light pollution, thus mitigating visual interference. Thirdly, users can observe the image content more closely. Fourthly, because the image is a floating image, it can display naked-eye 3D content, offering powerful functionality and expanding its application range. Fifthly, since it has no physical volume, users or their vehicles (such as cars, subways, etc.) can pass directly through the image without safety hazards. Furthermore, when a user is using a vehicle, the image is located directly in the center of the user's viewpoint, preventing the user from seeing the emitting device and thus avoiding visual interference for the driver. Simultaneously, the image is formed within the vehicle's interior space (such as the carriage or near the person inside), facilitating user observation of the advertising content.

[0035] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0036] like Figure 1Taking the subway scenario shown as an example, existing technology involves placing posters or pictures with patterns inside a lightbox, then illuminating the patterns with an internal light source to display the image. This method typically only displays flat images and cannot achieve 3D projection. Furthermore, users are already accustomed to lightbox advertising, making it difficult to effectively attract passenger attention and create a meaningful display. It also causes significant light pollution; current lightboxes are usually quite bright to meet advertising display requirements, which can be very irritating to the eyes in the dim environment of a subway tunnel. Additionally, the need for prolonged high-brightness image display means that both the lightbox and display panel must operate at high energy consumption for extended periods, resulting in high energy consumption. Moreover, this display method causes significant visual interference, and passengers in the subway car can only observe the patterns by looking out the windows. Finally, these traditional lightboxes are usually directly fixed to the target area, posing a risk of detachment.

[0037] Example:

[0038] The accompanying drawings illustrate a specific embodiment of the media-free holographic advertising display device of this utility model. Figure 2 , Figure 3 The system mainly includes a main positioning frame 1, an inner support plate 2, a medium-free holographic advertising module 3, and an outer fixing frame 4. The main positioning frame 1 is installed within an opening A0 in the target area A and is fixedly connected to the outer surface of the target area A via fasteners 5. The main positioning frame 1 primarily serves as the overall frame for installing the medium-free holographic advertising module 3. The inner support plate 2 is placed inside the main positioning frame 1 to support the medium-free holographic advertising module 3. The medium-free holographic advertising module 3 is placed on the inner support plate 2 to form a medium-free holographic advertising image 304. The outer fixing frame 4 is inserted into the main positioning frame 1 and magnetically attracted to it. The outer fixing frame 4 is also equipped with locking bolts 6 for locking and positioning the medium-free holographic advertising module 3, thereby achieving the positioning, installation, and fixation of the medium-free holographic advertising module 3.

[0039] Specifically, refer to Figure 4 , Figure 5 The main positioning frame 1 has the following structure: it includes two spaced vertical rods 101, and a first horizontal rod 102 is provided between the top and bottom ends of the two vertical rods 101, with the two first horizontal rods 102 arranged parallel to each other. A second horizontal rod 103, perpendicular to the first horizontal rod 102, is also provided at the top and bottom ends of the two vertical rods 101, with the four second horizontal rods 103 arranged parallel to each other.

[0040] The other end of the four second crossbars 103 is also provided with an outer frame 104. The middle of the outer frame 104 is hollowed out, and the upper and lower edges of the outer frame 104 are provided with multiple spaced fixing holes 104a. The fixing holes 104a are used for fasteners 5 to pass through. The fasteners 5 can be screws or other fasteners. By using the fasteners 5 to pass through the fixing holes 104a and the target area A, the outer frame 104 can be fixed to the target area A.

[0041] During installation, the vertical and horizontal sections of the main positioning frame 1 are placed within the opening A0 of the target area A. The outer frame 104 of the main positioning frame 1 covers the outside of the opening A0 of the target area A. After the outer frame 104 is fixedly connected to the target area A using the fastener 5, the entire main positioning frame 1 can be fixedly installed. The main positioning frame 1 is embedded in the target area A, and the outermost surface of the main positioning frame 1 is parallel to the surface of the target area A.

[0042] The bottom surface of the hollowed-out part in the middle of the outer frame 104 is also provided with multiple insertion holes 104b, which are spaced apart and used to install the outer fixing plate frame 4.

[0043] Combination Figure 5 The bottom of the two second crossbars 103 at the bottom of the main positioning frame 1 is also provided with a number of spaced rollers 103a. The rollers 103a are rotatably installed inside the bottom of the corresponding second crossbar 103 via a rotating shaft. By setting the rollers 103a, the friction during the installation of the main positioning frame 1 can be reduced.

[0044] The inner support plate 2 is placed inside the main positioning frame 1, as shown in the reference. Figure 6 The inner support plate 2 has a notch 2a at its corner that mates with two vertical rods 101. The inner support plate 2 can be pushed in from the outer frame 104 of the main positioning frame 1 along the two second horizontal rods 103 at the bottom, and positioned and installed by using the two notches 2a to mate with the two vertical rods 101. After installation, the bottom surface of the inner support plate 2 is in contact with one first horizontal rod 102 and two second horizontal rods 103 at the bottom.

[0045] The medium-free holographic advertising module 3 is placed on the inner support plate 2. The medium-free holographic advertising module 3 is used to form a medium-free holographic advertising image 304 for medium-free holographic advertising display, and to switch images according to external actions. (See reference...) Figure 7The structure of the medium-free holographic advertising module 3 is as follows: The medium-free holographic advertising module 3 includes an imaging box 301, within which is housed an image source component 302 and a medium-free holographic waveguide plate 303. The image source component 302 is used to generate the original advertising image, and the medium-free holographic waveguide plate 303 is used to convert the original advertising image into a medium-free holographic advertising image 304. The image source component 302 can be an electronic screen, projector, etc. In this embodiment, the medium-free holographic waveguide plate 303 is selected from the microchannel matrix waveguide flat panel of Xianghang (Shanghai) Technology Co., Ltd. Since this is an existing component, the underlying principles will not be elaborated upon.

[0046] The medium-free holographic advertising module 3 also includes a sensor and a control unit. The sensor is used to detect external actions, and the control unit controls the image source unit 302 to switch images based on the sensing results of the sensor. The sensor can be an infrared sensor, radar, ultrasonic sensor, etc.

[0047] The outer fixing plate frame 4 is inserted into the main positioning frame 1, as shown in the figure. Figure 8 , Figure 9 The structure of the outer fixing frame 4 is as follows: the outer fixing frame 4 includes a fixing frame 401. The size of the fixing frame 401 is smaller than the size of the hollowed-out part in the middle of the outer frame 104 of the main positioning frame 1. The bottom of the fixing frame 401 is provided with a plurality of insert posts 401a corresponding one-to-one with each insert hole 104b on the outer frame 104. A connecting edge 402 is provided on one side of the top of the fixing frame 401, and the connecting edge 402 overlaps the outer surface of the outer frame 104 of the main positioning frame 1.

[0048] When installing the outer fixing frame 4, align the bottom insert 401a with the insertion hole 104b and insert it. The fixing frame 401 can be inserted into the outer frame 104. After the outer fixing frame 4 is installed, there is a certain distance between the top of the fixing frame 401 and the top of the outer frame 104. This distance is used to facilitate the placement and removal of the outer fixing frame 4. After the outer fixing frame 4 is installed, the connecting edge 402 overlaps the outer surface of the outer frame 104. When removing the outer fixing frame 4, lift the outer fixing frame 4 upwards so that the insert 401a disengages from the insertion hole 104b, and the outer fixing frame 4 can be removed from the outer frame 104.

[0049] Combination Figure 9 A magnetic element 402a is provided on the inner side of the connecting edge 402. In this embodiment, the magnetic element 402a is embedded in the inner side of the connecting edge 402. Multiple magnetic elements 402a can be arranged at intervals along the connecting edge 402 to increase the adsorption force. At the same time, the entire outer frame 104 or at least the upper edge is made of magnetic material, so that the connecting edge 402 can be adsorbed and attached to the outer frame 104 through the magnetic element 402a, ensuring that the installation of the outer fixing plate frame 4 is more stable. However, it is not limited to this. The magnetic element 402a can also be provided on the inner side of the connecting edge 402, which can also play an adsorption role.

[0050] The fixed frame 401 is provided with multiple vertically spaced locking holes 401b on both sides. The locking bolts 6 can pass through the locking holes 401b and press against the medium-free holographic advertising module 3, thereby realizing the positioning and fixing of the medium-free holographic advertising module 3.

[0051] An opening 401c is provided in the middle of the fixed frame 401. The opening 401c is used to facilitate imaging of the medium-free holographic advertising module 3.

[0052] During the specific installation of this media-free holographic advertising display device, a hole A0 is pre-drilled in the target area A. Then, the vertical and horizontal sections of the main positioning frame 1 are pushed into the hole A0, and the outer frame 104 covers the outside of the hole A0. Figure 10 Then, the inner support plate 2 is placed inside the main positioning frame 1, and the two notches 2a of the inner support plate 2 are used to cooperate with the two vertical rods 101 of the main positioning frame 1 for positioning and installation; such as Figure 11 Next, the medium-free holographic advertising module 3 is placed on the inner support plate 2; as follows: Figure 12 Finally, the outer fixing plate frame 4 is inserted into the outer frame 104 of the main positioning frame 1. The connecting edge 402 of the outer fixing plate frame 4 overlaps the outer surface of the outer frame 104 and is firmly attached to the outer frame 104 by magnetic attraction 402a. Then, the locking bolt 6 is passed through the locking hole 401b of the outer fixing plate frame 4 and pressed against the medium-free holographic advertising module 3 to achieve the positioning and installation of the medium-free holographic advertising module 3. Finally, the fixing piece 5 is passed through the fixing hole 104a of the main positioning frame 1 and the target area A to achieve the fixed installation of the entire device. When using the device of this utility model, if... Figure 1 The distance of the non-medium holographic advertising module 3 to the floating image is located inside the subway car and 1-3cm away from the window. It can form an image without disturbing other passengers. The distance D1 between the user and the floating image is significantly smaller than the distance D2 between the passenger and the pattern in the light box in the prior art, so that the user can observe the content of the image at a closer distance.

[0053] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model.
