Description

Technical Field

[0001] This invention relates to the technical field of projection equipment, and more specifically, to an immersive crystal ball 3D visual projection device. Background Technology

[0002] With the development of science and technology and the improvement of people's requirements for quality of life, digital photo frames, as electronic products that can flexibly display digital images, have been widely used in home decoration, gift-giving, and other scenarios. Most existing digital photo frames adopt a flat rectangular structure, with main components including a display screen, casing, motherboard, and power supply. Images are displayed directly on the screen, and the display can be switched manually or automatically according to the user's needs. Although this solves the problem of the limited display format of traditional paper photo frames, there is still considerable room for improvement in visual presentation and decorative appearance.

[0003] To enhance the visual experience, several improvements have emerged in existing technologies for digital photo frames. On one hand, some digital photo frames enhance display effects through transparent substrates, backlighting technology, or 3D displays. For example, transparent floating digital photo frames that use three layers of tempered glass with backlighting to achieve a floating image effect can reduce the bulkiness of traditional electronic screens. Alternatively, a regular 2D display can be replaced with a 3D display to present images in a three-dimensional form. On the other hand, some technologies attempt to create a sense of depth by creating a gap between the transparent cover and the image, or by adding reflective layers, pattern layers, or other structures to the transparent substrate to create an atmosphere within a three-dimensional space.

[0004] In summary, existing digital photo frames have the following shortcomings: 1. Traditional digital photo frames have a simple appearance and are mostly rectangular flat structures, resulting in poor visual presentation and failing to achieve the ambiance brought by 3D display effects; 2. Existing digital photo frames with 3D effects mostly rely on dedicated 3D displays to achieve the stereoscopic effect, or create a sense of space through other means. This is costly, structurally complex, and provides users with a relatively limited visual experience. Summary of the Invention

Detailed Implementation

[0026] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: Example

[0027] This embodiment discloses an immersive crystal ball 3D visual projection device for displaying digital images and presenting a stereoscopic visual effect. The projection device includes an interlocking hemisphere 1 and a mounting base 2. The hemisphere 1 serves as the carrier of the projected image and has an outer spherical surface 12 and a mounting surface 11 facing the mounting base 2. The mounting surface 11 is a circular plane. The hemisphere 1 is preferably made of crystal material. During the production of the hemisphere 1, by changing its material ratio and size, the light entering from the mounting surface 11 can produce a specific refraction angle and optical magnification, resulting in a 3D visual presentation effect. The mounting base 2 is a hemispherical hollow shell structure with an inner cavity that is a hemispherical mounting cavity 21. It is provided with a mounting opening 211 facing the mounting surface 11 of the hemisphere 1. When the hemisphere 1 and the mounting base 2 are connected to each other, the edge of the mounting surface 11 of the hemisphere 1 fits against the edge of the mounting opening 211 and closes the mounting cavity 21. The two are detachably and fixedly connected to each other through a sealing structure.

[0028] When the projection device is in use, the hemisphere 1 is located above the mounting base 2. In order to ensure that the hemisphere 1 can be tightly connected to the mounting base 2, a sealing groove 212 is provided on the mounting base 2 at the edge of the mounting opening 211. The sealing groove 212 surrounds the mounting opening 211 in a circumferential direction. The sealing groove 212 can be filled with sealant or provided with an adhesive annular sealing component. When the hemisphere 1 is fastened to the mounting opening 211, the sealing component can bond the hemisphere 1 and the mounting base 2 together, thereby making the two tightly connected to form a sphere. The mounting cavity 21 is equipped with a display screen 3 and a control device 4. The display screen 3 is preferably an LCD liquid crystal display screen 3. The display surface of the display screen 3 is parallel and faces the mounting surface 11. The control device 4 is located below the display screen 3. The control device 4 is electrically connected to the display screen 3 and is used to supply power to the display screen 3 and transmit image signals to the display screen 3. The image of the display screen 3 is projected into the interior of the hemisphere 1 through the mounting surface 11. The user can directly observe the image through the outer spherical surface 12.

[0029] Specifically, the control device 4 includes a display control board 41 and a power control board 42, both preferably using PCBA circuit boards. The display control board 41 is parallel to the display screen 3 and is fixedly mounted on the mounting base 2. The display control board 41 is provided with a display connector 411. Correspondingly, the display screen 3 is provided with a display interface (not shown in the figure) for plugging into the display connector 411. The display connector 411 is plugged into the display interface of the display screen 3. The display control board 41 can supply power to the display screen 3 through the display connector 411 and the display interface, and transmit image signals to the display screen 3, thereby controlling the image display on the display screen 3. In addition, several control buttons 41 are installed on the edge of the display control board 41. 2. The control button 412 is a mechanical pressing module that generates a control electrical signal when pressed. Correspondingly, a key hole 22 corresponding to the position of the control button 412 is provided on the side wall of the mounting base 2. A keycap 23 is installed in the key hole 22, covering the control button 412, protecting the control button 412, and facilitating user pressing. In this embodiment, three control buttons 412 are provided. The user can interact with the display control board 41 by pressing the control buttons 412, thereby enabling the display control board 41 to execute different commands. In this embodiment, the three control buttons 412 serve as the main power switch, up switch, and down switch function buttons for the display screen 3, respectively, realizing interactive functions. A dustproof pad 31 is provided between the display screen 3 and the display control board 41. The dustproof pad 31 is used to seal the space of the mounting cavity 21 below the display screen 3, reducing the degree of dust entering the mounting cavity 21 during product use, and ensuring the service life and operational stability of the control device 4.

[0030] The power control board 42 is positioned below the display control board 41 and is mounted perpendicular to the display control board 41. The power control board 42 and the display control board 41 are electrically connected for power distribution and information exchange. A battery 5 for energy storage is connected to the power control board 42. The power control board 42 can distribute the power of the battery 5 and control its charging and discharging logic to ensure normal charging and discharging and safe use of the battery 5. The battery 5 is installed inside the mounting cavity 21. To securely mount the display control board 41 and the power control board 42 in the mounting base 2, two positioning seats 25 are provided inside the mounting cavity 21. The two positioning seats 25 are arranged radially opposite each other along the mounting base 2, and each positioning seat 25 is vertically open. A positioning hole 252 is provided, and correspondingly, two connecting holes 413 are provided on the display control board 41. The connecting holes 413 are round holes, and each connecting hole 413 corresponds vertically to a positioning hole 252. By passing screws or other connecting parts through the connecting holes 413 and the positioning holes 252 and locking them, the display control board 41 can be locked on the positioning seat 25 to ensure the stability of the position of the display control board 41. In addition, each positioning seat 25 has a vertical snap-fit ​​groove 251, and the openings of the snap-fit ​​grooves 251 face each other. The vertically arranged power control board 42 is inserted between the two snap-fit ​​grooves 251. By limiting the position of the display control board 41 and the snap-fit ​​grooves 251, the position of the power control board 42 can be locked.

[0031] An interface module 421 is installed at the lower part of the power control board 42. The interface module 421 is used to connect the power cord. After the power cord is connected to the mains power, the power control board 42 can distribute the power to the battery 5 through circuit logic to charge the battery 5. A charging hole 24 is opened at the bottom of the mounting base 2. The charging hole 24 corresponds to the interface module 421. The user can connect the power cord plug to the interface module 421 by inserting it into the charging hole 24. Under the control of the circuit logic of the power control board 42, the purpose of charging the battery 5 is realized.

[0032] In addition, a speaker 6 is installed inside the mounting cavity 21. The speaker 6 is connected to the display control board 41, which integrates an audio control chip. This allows the display control board 41 to control the speaker 6 to play audio while the display screen 3 is displaying pictures or videos, improving the functionality and practicality of the product. The bottom of the mounting cavity 21 has a receiving groove 26 that matches the shape of the speaker 6. The speaker 6 is embedded in this receiving groove 26. Furthermore, multiple speaker holes 261 are formed on the side wall of the mounting base 2 at the receiving groove 26. The speaker holes 261 are circular through holes, arranged in a continuous array and corresponding to the speaker 6, ensuring that the sound emitted by the speaker 6 can be transmitted through the holes.

[0033] The principle of this invention is that after the display control board 41 is powered on, it can transmit the images or videos stored therein to the display screen 3 in the form of electrical signals, so that the display screen 3 can display the images and videos. At the same time, the images or videos displayed on the display screen 3 can be directly projected onto the hemisphere 1 through the mounting surface 11. By setting specific optical parameters such as curvature and refractive index for the hemisphere 1, it can be matched with the size and installation position of the display screen 3, so that the image of the display screen 3 can be completely projected through the hemisphere 1, and the observer can observe the full-screen magnification effect through the hemisphere. Moreover, the optical characteristics of the hemisphere 1 can make the image naturally form a 3D visual effect. On the one hand, it realizes the atmosphere brought by the 3D display effect, and on the other hand, it does not require additional 3D display modules or magnifying lenses. The structure is simple and the cost is lower, which can bring a better user experience.

[0034] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
