[0036] Reference Figures 1 to 4 An embodiment of the present invention provides a dynamic display device based on magnetic force control, including a power-carrying coil 1, the shape of which is configured to display information; and magnetic particles 2 are configured to be magnetically adsorbed by the power-carrying coil 1 after being energized.

[0037] In this embodiment, a dynamic display device based on magnetic force control is primarily composed of a specifically shaped energized coil 1 and magnetic particles 2. The energized coil 1 is designed to be shaped like various characters, graphics, or symbols to display specific information. Specifically, this is accomplished by configuring the energized coil 1 as a seven-segment digit array or a dot matrix array. The magnetic particles 2 are evenly distributed in the space surrounding the energized coil 1. When specific information is required, the correspondingly shaped energized coil 1 is energized. The current passing through the coil generates a magnetic field that magnetically attracts the surrounding magnetic particles 2 to the energized coil 1, forming a clear display pattern. This design avoids the flickering light of traditional display devices, reducing light pollution and eye fatigue. Because it does not involve traditional light emission and radiation principles, radiation damage is significantly minimized. By changing the shape and energization pattern of the energized coil 1, a variety of information can be easily displayed, offering a high degree of flexibility and customization. Compared to traditional display devices, this device consumes less energy during operation, making it more energy-efficient and environmentally friendly. Furthermore, the magnetic attraction method ensures a stable display pattern, free from external interference, improving display quality.

[0038] Furthermore, it includes an outer shell 3 having an inner cavity 301 ; the inner cavity 301 is a cylindrical cavity having a planar top wall 302 and an annular side wall 303 , and there are several energized coils 1 , which are distributed in an array on the planar top wall 302 .

[0039] In this embodiment, the outer shell 3 has an inner cavity 301. The inner cavity 301 is a cylindrical cavity with a planar top wall 302 and an annular side wall 303. A plurality of energized coils 1 are arranged in an array on the planar top wall 302. Magnetic particles 2 are distributed in the inner cavity 301. When display is required, it further includes:

[0040] Furthermore, the inner shell 4 is rotatably disposed in the inner cavity 301 , the inner shell 4 is annular, and the outer wall of the inner shell 4 is in sliding contact with the annular side wall 303 .

[0041] In this embodiment, the inner shell 4 is annular and is rotatably arranged in the inner cavity 301, and its outer wall is in close sliding contact with the annular side wall 303. The magnetic particles 2 fill the space between the inner shell 4 and the outer shell 3. When the device is running, the inner shell 4 continues to rotate. Due to the rotation of the inner shell 4, the magnetic particles 2 can maintain a flowing state, avoiding agglomeration or uneven distribution caused by long-term stillness. When specific content needs to be displayed, the corresponding energized coil 1 is energized to generate a magnetic field to adsorb the magnetic particles 2 to form a clear display pattern. The rotation of the inner shell 4 ensures the uniform flow of the magnetic particles 2, making the display effect more stable and consistent. The flowing magnetic particles 2 can respond to changes in the magnetic field more quickly and accurately, thereby improving the clarity and accuracy of the display.

[0042] Furthermore, it also includes a partition member 5 arranged on the annular side wall 303, dividing the inner cavity 301 into an upper inner cavity 304 and a lower inner cavity 305, and the magnetic particles 2 are located in the upper inner cavity 304. It also includes a filter rod 6 whose two ends are arranged on the side walls of the inner shell 4 and are located in the upper inner cavity 304. The filter rod 6 is configured so that after the inner shell 4 drives the filter rod 6 to rotate, the filter rod 6 abuts against the magnetic particles 2, pushing the magnetic particles 2 to slide.

[0043] In this embodiment, when the inner shell 4 rotates, it drives the filter rod 6 to rotate together. During the rotation process, the filter rod 6 abuts against the magnetic particles 2, thereby pushing the magnetic particles 2 to slide in the upper inner cavity 304. When display is required, the corresponding energized coil 1 is energized to generate a magnetic field to adsorb the magnetic particles 2 to form a display pattern. The driving action of the filter rod 6 enables the magnetic particles 2 to flow more actively, avoiding deposition and uneven distribution. It ensures that the magnetic particles 2 can quickly reach the adsorption area of ​​the energized coil 1, thereby improving the response speed of the display. It helps to maintain the dynamic balance of the magnetic particles 2 inside the device and ensure the long-term stable operation of the device. At the same time, the fast and accurate flow of the magnetic particles 2 can reduce the power-on time and power of the energized coil 1, reducing the energy consumption of the device.

[0044] Furthermore, the filter rod 6 divides the upper inner cavity 304 into a storage cavity 306 and an adsorption cavity 307. The energized coil 1 is arranged on the plane top wall 302 corresponding to the adsorption cavity 307. The filter rod 6 has a filter hole 601, which connects the storage cavity 306 and the adsorption cavity 307. The magnetic particles 2 are located in the storage cavity 306. The magnetic particles 2 are configured so that after the inner shell 4 drives the filter rod 6 to rotate, the magnetic particles 2 slide from the storage cavity 306 through the filter hole 601 and then enter the adsorption cavity 307, or slide from the adsorption cavity 307 through the filter hole 601 and then enter the storage cavity 306.

[0045] In this embodiment, the outer shell 3 has an upper inner cavity 304, which is divided by a filter rod 6 into a storage cavity 306 and an adsorption cavity 307. An energized coil 1 is mounted on the planar top wall 302 corresponding to the adsorption cavity 307. Filter holes 601 are distributed on the filter rod 6, connecting the storage cavity 306 and the adsorption cavity 307. Magnetic particles 2 are stored in the storage cavity 306. During operation, the inner shell 4 rotates, driving the filter rod 6. When the filter rod 6 rotates to a specific position, the magnetic particles 2, driven by gravity and the force generated by the rotation of the inner shell 4, slide from the storage cavity 306 through the filter holes 601 into the adsorption cavity 307. When the inner shell 4 drives the filter rod 6 in the opposite direction, the magnetic particles 2 slide from the adsorption cavity 307 through the filter holes 601 back into the storage cavity 306. After the magnetic particles 2 enter the adsorption cavity 307, power is applied to the energized coil 1, attracting them and forming a display pattern. Through such design and action, a large amount of magnetic particles 2 will not be accumulated in the adsorption chamber 307, thus avoiding the situation of unclear reading or internal failure. The reasonable division of the storage chamber 306 and the adsorption chamber 307 improves the space utilization efficiency of the upper inner cavity 304 and makes the device structure more compact. The cooperation of the filter rod 6 and the filter hole 601 can accurately regulate the flow of magnetic particles 2 between the two chambers to ensure the accuracy of the display. The rapid switching of magnetic particles 2 in different chambers is achieved, which is convenient for flexible changing of the display state. It also prevents the accumulation of magnetic particles 2 in the adsorption chamber 307, reducing the risk of unclear reading and internal failure.

[0046] Furthermore, the filter rods 6 are arranged in pairs, the diameters of the two filter rods 6 are smaller than the diameter of the inner shell 4, and the two filter rods 6 are symmetrically arranged about the diameter of the inner shell 4. The two filter rods 6 divide the upper inner cavity 304 into an adsorption cavity 307 and two storage cavities 306 located on both sides of the adsorption cavity 307.

[0047] In the present embodiment, the inner shell 4 drives the two filter rods 6 to rotate when it rotates. When the filter rod 6 rotates to a specific position, the magnetic particles 2 will slide from the storage chamber 306 through the filter hole 601 into the adsorption chamber 307, or slide from the adsorption chamber 307 through the filter hole 601 back to the storage chamber 306 under the action of gravity and the driving force generated by the rotation. After the magnetic particles 2 enter the adsorption chamber 307, the energized coil 1 is energized, and the magnetic particles 2 are adsorbed to form a display pattern. The design of the two storage chambers 306 increases the storage capacity of the magnetic particles 2, which can meet the needs of long-term and complex displays. The symmetrically arranged filter rods 6 and storage chambers 306 help the magnetic particles 2 to be more evenly distributed and flow, ensuring the consistency of the display. More magnetic particles 2 supply and a more reasonable layout make the display clearer, richer and more stable.

[0048] Furthermore, a bearing 7 is provided on the outer wall of the inner shell 4 and the inner wall of the lower inner cavity 305 .

[0049] In this embodiment, bearing 7 is positioned between the outer wall of inner housing 4 and the inner wall of lower inner cavity 305. During operation, bearing 7 enables smoother rotation of inner housing 4 within outer housing 3, thereby achieving the various display functions required. The provision of bearing 7 significantly reduces friction between inner housing 4 and outer housing 3 during rotation, reducing energy loss and component wear. This ensures smooth and precise rotation of inner housing 4, contributing to a more accurate and detailed display. This makes the rotation of inner housing 4 more stable and reliable, reducing display failures caused by poor rotation.

[0050] Furthermore, the inner shell 4 has an inner gear ring 401, the lower inner cavity 305 has a planar bottom wall 308, and also includes a first gear 8 rotatably set on the planar bottom wall 308, the first gear 8 is engaged with the inner gear ring 401, and the first gear 8 is configured to drive the inner shell 4 to rotate after rotation.

[0051] In this embodiment, when the first gear 8 rotates, due to its meshing relationship with the inner gear ring 401, it will drive the inner shell 4 to rotate. The rotation of the inner shell 4 then enables the flow and adsorption of the magnetic particles 2 between different chambers to achieve the purpose of display. The transmission is achieved through gear meshing, ensuring the accuracy and stability of the rotation of the inner shell 4. The rotation speed and angle of the first gear 8 can be precisely controlled, thereby precisely controlling the rotation of the inner shell 4 and achieving more sophisticated display control. At the same time, the gear transmission efficiency is high, which can effectively transmit power to the inner shell 4 and reduce energy loss. This transmission method takes up less space inside the device, which contributes to the compact design of the overall structure. It makes the rotation of the inner shell 4 more stable, reduces jitter and deviation, and improves the display quality.

[0052] Furthermore, a rotation driving member 9 is provided on the plane bottom wall 308 to drive the first gear 8 to rotate.

[0053] In this embodiment, when rotation of the inner housing 4 is required, the rotary drive 9 is activated and drives the first gear 8 to rotate. The meshing of the first gear 8 with the inner ring gear 401 drives the inner housing 4 to rotate, thereby enabling the flow and adsorption of the magnetic particles 2 between the different chambers, achieving the desired display effect. The provision of the rotary drive 9 enables automated control of the rotation of the inner housing 4, eliminating the need for manual intervention and improving ease of use. By configuring the parameters of the rotary drive 9, the rotation speed and angle of the inner housing 4 can be flexibly adjusted to suit different display requirements.

[0054] Furthermore, the array shape of the energized coils 1 is a line, a rectangle or a circle.

[0055] In this embodiment, energized coils 1 with different array shapes can achieve a variety of display patterns, meeting diverse display requirements. The array shape of the energized coils 1 can be flexibly selected based on specific application scenarios and display requirements, improving the applicability of the device. Specific array shapes facilitate more precise control of the adsorption position and quantity of magnetic particles 2, improving display accuracy and quality.
