Description

Technical Field

[0001] This utility model relates to the field of projection display equipment, and in particular to a three-dimensional stereoscopic display device with sound, light, electricity and electricity. Background Technology

[0002] Traditional display equipment, such as static light boxes, displays fixed and singular content, cannot present dynamic information, and has limited expressive power. While ordinary projection displays can play dynamic images, they usually require a dedicated dark environment and a high-gain screen, resulting in a lack of background support, insufficient sense of three-dimensionality and immersion. In addition, the functional modules of existing equipment (such as speakers) are mostly external or independently installed, resulting in poor overall integration and inconvenient installation and maintenance.

[0003] Therefore, how to efficiently and conveniently combine dynamic projection with static background, and achieve integrated and rapid maintenance of various functional modules, has become an urgent problem to be solved in this field. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a three-dimensional audio-visual display device. Its core purpose is to achieve seamless integration of dynamic projection and static backlight through ingenious mechanical structure and optical design, and to integrate high-quality sound to form an immersive audio-visual display experience.

[0005] This utility model is achieved using the following technical solution: a three-dimensional stereoscopic display device with sound, light, and electricity, used in conjunction with an external projector, comprising: The display box is composed of a lightbox and a lightbox cover connected together. An opening is provided through the outside of the lightbox cover, and an acrylic panel is fixedly installed inside the opening. The acrylic panel is made of transparent material, which makes it easy to observe the scene inside the lightbox. A lightbox fabric is used to present a static background and is installed on the back of an acrylic sheet. A light-emitting panel is installed on the inner wall of the lightbox. When the light-emitting panel is powered on, it is connected to the lightbox fabric to illuminate the static background on the surface of the lightbox fabric. The projection film is fixedly attached to the outside of the acrylic panel to facilitate the projection of the projector's image. Combined with the illuminated lightbox cloth, it can achieve a combination of dynamic and static scenes. The audio components are detachable and can be installed on both sides of the display cabinet for sound playback. Together with the lightbox cloth and projection film, they can achieve a complete "sound, light, electricity" combined display effect.

[0006] As a further improvement to the above solution, the light box and the light box cover are provided with circular mounting grooves on the connecting surfaces on both sides. After the audio component is inserted into the mounting groove and rotated, the connected light box and the light box cover can be locked.

[0007] As a further improvement to the above solution, guide holes are provided at the four corners of the outer side of the light box, and guide pins are provided at the four corners of the inner side of the light box cover. The guide pins and guide holes can be movably inserted to facilitate the precise docking of the light box cover and the light box.

[0008] As a further improvement to the above solution, the back of the acrylic sheet and the lightbox fabric are connected by a snap fastener, with the male and female snap fasteners respectively located on the back of the acrylic sheet and the four corners of the lightbox fabric.

[0009] As a further improvement to the above solution, the light-emitting panel is an LED light panel.

[0010] As a further improvement to the above solution, the speaker component integrates a wireless receiving module and an audio decoding unit, and the speaker component connects to an external audio source device wirelessly.

[0011] As a further improvement to the above solution, the light box is provided with two sets of symmetrical plug-in slots on the outside, and the inner wall of the inner end of the mounting slot is provided with an L-shaped rotating slot. The plug-in slot, the L-shaped rotating slot, and the mounting slot are interconnected.

[0012] As a further improvement to the above solution, two sets of symmetrical L-shaped locking blocks are fixedly connected near the inner side of the audio component. After the audio component is inserted into the mounting slot, the L-shaped locking blocks slide into the insertion slot and rotate between the L-shaped rotating slots to lock the connected light box and light box cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model presents a dynamic main image through the projection film on the outside of the light box, while the light box cloth inside the light box is illuminated by the light-emitting light panel to form a static background. The two are perfectly superimposed through the transparent acrylic plate to create a rich and three-dimensional visual effect that combines reality and illusion. The expressiveness far exceeds the traditional single display form. Combined with the sound components to play sound, it ultimately provides a complete audio-visual display solution (integrating light and shadow (dynamic projection + static backlight), sound (integrated sound system), and electric lighting), which greatly enhances the audience's audio-visual experience.

[0014] (2) This utility model innovatively designs the audio component as a structural locking component. Through a unique rotating locking mechanism, the audio component can be quickly installed and disassembled, while the light box and light box cover are locked. This design reduces the use of additional fasteners, making the equipment look neat and the structure highly integrated. Attached Figure Description

[0018] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please combine Figure 1-4The display equipment mainly includes a display cabinet, an acrylic panel 3 component, and an audio component 8. The display cabinet is composed of two connected parts: a lightbox 1 and a lightbox cover 2. To achieve quick and precise alignment between the lightbox 1 and the lightbox cover 2, guide holes 101 are provided at the four corners of the outer side of the lightbox 1, while guide pins 201 are provided at corresponding positions on the inner side of the lightbox cover 2. During installation, inserting the guide pins 201 into the guide holes 101 ensures complete alignment between the two parts, laying the foundation for subsequent locking steps.

[0022] The acrylic panel 3 is the core component for achieving the optical effect. The acrylic panel 3 is made of transparent material, and its size matches the opening on the front of the lightbox cover 2, allowing it to be installed through the opening. The lightbox fabric 4 is installed on the back of the acrylic panel 3 using snap fasteners 401. (Specifically, the male and female snap fasteners 401 are respectively located on the back of the acrylic panel 3 and at the four corners of the lightbox fabric 4. This connection method makes replacing the lightbox fabric 4 extremely convenient, allowing users to easily switch between different static backgrounds according to the display theme.) A projection film 5 is tightly adhered to the outer side of the acrylic panel 3. This projection film 5 is used to clearly display the dynamic images projected by the external projector 9. A backlight panel 6 is installed on the inner wall of the lightbox 1. In this embodiment, a high-brightness, low-power LED panel is preferably used. When the light panel 6 is powered on, its light evenly illuminates the static pattern on the lightbox cloth 4. The illuminated static pattern, through the transparent acrylic plate 3, becomes the background of the dynamic image on the projection film 5, thus creating a three-dimensional visual effect that combines movement and stillness and has distinct layers.

[0023] The speaker assembly 8 not only plays audio but also functions as a mechanical locking component. It integrates a wireless receiver module (such as a Bluetooth or Wi-Fi module) and an audio decoding unit, enabling it to connect wirelessly to external audio source devices (such as mobile phones or computers) to receive and play audio signals, eliminating the hassle of external wiring. It's worth noting that the speaker assembly 8 has a notch (not shown) on its outer side, allowing operators to insert their fingers for easy rotation or insertion during installation.

[0024] A circular mounting groove 7 is defined on the connecting surfaces of the light box 1 and the light box cover 2 on both sides. The audio component 8 is inserted into the mounting groove 7. Two sets of symmetrical L-shaped clips 801 are fixedly connected near the inner side of the audio component 8. Correspondingly, two sets of symmetrical insertion grooves 701 matching the shape of the L-shaped clips 801 are provided on the outer side of the light box 1. An L-shaped rotating groove 702 is provided on the inner wall of the inner end of the mounting groove 7. The insertion groove 701, the L-shaped rotating groove 702, and the mounting groove 7 are interconnected.

[0025] The assembly and locking process of this device is as follows: (1) First, install the lightbox cloth 4 with the desired pattern on the back of the acrylic plate 3 using snap fasteners 401.

[0026] (2) Insert the acrylic sheet 3 into the opening of the light box cover 2.

[0027] (3) Align the guide pin 201 of the light box cover 2 with the guide hole 101 of the light box 1 to make the two initially connected.

[0028] (4) Align the L-shaped locking block 801 on the speaker assembly 8 with the insertion slots 701 on both sides of the cabinet, and then push the speaker assembly 8 inward so that the L-shaped locking block 801 slides into the insertion slot 701 until it reaches the bottom; at this time, rotate the speaker assembly 8 (usually rotate 90 degrees), and the L-shaped locking block 801 will slide from the bottom of the insertion slot 701 into the L-shaped rotating slot 702 that is connected to it.

[0029] Through this rotation action, the audio component 8 uses the L-shaped locking block 801 and the L-shaped rotating groove 702 to firmly lock the light box 1 and the light box cover 2 together. The disassembly process is the reverse of the above steps. By rotating and pulling out the audio component 8, the cabinet can be easily separated, and the internal light box cloth 4 or light-emitting panel 6 can be replaced or maintained.

[0030] Based on this, it should be added that most of the insertion slot 7 is located on the outside of the light box 1, and a small part is located on the outside of the light box cover 2, due to the thinness of the light box cover 2. Meanwhile, the two sets of L-shaped rotating slots 702 on the inner wall of the insertion slot 7 are partly on the inner wall of the light box 1 and partly on the inner wall of the light box cover 2. Thus, when the two sets of L-shaped locking blocks 801 on the outside of the audio component 8 rotate, the two sets of L-shaped locking blocks 801 respectively engage with the two sets of L-shaped rotating slots 702 on the inner walls of the light box 1 and the light box cover 2, achieving a locking effect. It should also be added that the L-shaped locking blocks 801 and the L-shaped rotating slots 702 are further fixed by friction through friction pads, and will not rotate when stationary.

[0031] Working principle: Projector 9 projects dynamic video images onto projection film 5. At the same time, light panel 6 is lit up, illuminating the static background pattern on lightbox cloth 4. At this time, the final image seen by the audience is a three-dimensional image that is deeply integrated with the dynamic subject on projection film 5 and the static background on lightbox cloth 4, which has a strong visual impact. With the addition of audio component 8, which is wirelessly connected to the audio source, synchronized background sound is played, providing an immersive audio-visual integrated display experience.

[0032] Finally, it should be added that, in actual manufacturing, the above solution can be optimized according to actual needs. There is no need to separate the display cabinet into light box 1 and light box cover 2. It can be directly molded as a whole. Furthermore, the mounting slot 7 can be eliminated, and the audio component 8 can be placed directly in the external space (for example, placed around the site, or the audio component 8 can be integrated into the outside of the projector 9).

[0033] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0034] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
