Detailed Implementation

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] This embodiment of the utility model provides a magnetic holder 1 for a portable screen 2, such as... Figures 1 to 3 As shown, the magnetic holder 1 includes a base 11, a support arm 12, and a magnetic adsorption plate 13. One end of the support arm 12 is mounted on the base 11, and the magnetic adsorption plate 13 is mounted on the other end of the support arm 12. The magnetic adsorption plate 13 is provided with a first magnetic adsorption element 131, which is used to magnetically adsorb onto the magnetic adsorption area 21 on the back of the portable screen 2, so that the portable screen 2 is magnetically fixed to the first magnetic adsorption element 131 in use. The magnetic holder 1 also includes a rotating connector 14, which is fixedly connected to the side of the magnetic adsorption plate 13 away from the back of the portable screen 2 in use, and is rotatably connected to the other end of the support arm 12.

[0033] The magnetic bracket 1 of this utility model is equipped with a magnetic adsorption plate 13, on which a first magnetic adsorption element 131 is provided. The first magnetic adsorption element 131 is used to magnetically adsorb onto the magnetic adsorption area 21 on the back of the portable screen 2, so that the portable screen 2 is magnetically fixed to the first magnetic adsorption element 131 when in use. In this way, when using the portable screen 2, it can be connected and installed through the magnetic adsorption of the first magnetic adsorption element 131 and the magnetic adsorption area 21. The portable screen 2 is installed and used through the magnetic adsorption of the magnetic adsorption plate 13, which is not only convenient to assemble when in use, but also very convenient to disassemble when it is needed for storage, movement and transportation. Furthermore, by rotating the connector 14 and rotating it to one end of the support arm 12, the portable screen 2 can be adjusted to a greater angle, which is convenient for use.

[0034] Specifically, a magnetically adsorbent component, such as the second magnetic adsorbent 24 described below, can be provided at the magnetic adsorption area 21. Between the first magnetic adsorbent 131 and the second magnetic adsorbent 24, one can be a magnet and the other a metal component capable of magnetic attraction, or both can be magnets. Preferably, both the first magnetic adsorbent 131 and the second magnetic adsorbent 24 are magnets, resulting in a stronger adsorption force.

[0035] Specifically, such as Figure 4As shown, regarding the specific configuration of the magnetic adsorption plate 13, in the first embodiment, the first magnetic adsorption element 131 is a magnet; the magnetic adsorption plate 13 has an installation groove 132 on the side facing the back of the portable screen 2, and the first magnetic adsorption element 131 is installed in the installation groove 132. The first magnetic adsorption element 131 is made of magnet material, which can generate a strong magnetic field, forming a stable magnetic connection with the magnetic adsorption area 21 (such as the second magnetic adsorption element 24) on the back of the portable screen 2, ensuring that the portable screen 2 will not easily fall off during use, thus improving the reliability of use. The design of the installation groove 132 provides good positioning and fixing for the first magnetic adsorption element 131, preventing the first magnetic adsorption element 131 from shifting or falling off during use, and ensuring the structural stability of the magnetic bracket 1. The first magnetic adsorption element 131 is installed in the installation groove 132, so that the magnetic adsorption plate 13 and the first magnetic adsorption element 131 form a whole, the overall structure is more compact, and the protrusion of the first magnetic adsorption element 131 will not affect the cooperation between the bracket and other components, thus improving the overall performance of the magnetic bracket 1. The first magnetic adsorption component 131 can be bonded to the mounting groove 132 with glue or the like.

[0036] In the first embodiment, the first magnetic adsorption component 131 is fan-shaped, and the shape of the mounting groove 132 is adapted to the shape of the first magnetic adsorption component 131. Four first magnetic adsorption components 131 are arranged evenly around the center of the magnetic adsorption plate 13. The even arrangement of the four fan-shaped first magnetic adsorption components 131 around the center of the magnetic adsorption plate 13 makes the magnetic force more evenly distributed on the magnetic adsorption plate 13, ensuring that the portable screen 2 receives a balanced magnetic attraction force in all directions. This prevents the portable screen 2 from tilting or falling off due to uneven magnetic force, thus improving the stability of the portable screen 2. The fan-shaped design allows the first magnetic adsorption component 131 to cover a larger area within a limited space, resulting in more sufficient contact with the magnetic adsorption area 21 on the back of the portable screen 2, thereby enhancing the adsorption effect.

[0037] In the first embodiment, the magnetic adsorption plate 13 is recessed to the side facing the back of the portable screen 2 to form a recessed groove 133. A mounting groove 132 is formed in the recessed groove 133, and a decorative piece 134 covers the recessed groove 133. The design of the recessed groove 133 and the decorative piece 134 makes the surface of the magnetic adsorption plate 13 flatter and smoother, resulting in a tighter fit with the back of the portable screen 2, a more aesthetically pleasing overall appearance, and a unified effect. Specifically, the decorative piece 134 can be a silicone sheet, a rubber sheet, etc., which can be glued to the recessed groove 133 to cover the first magnetic adsorption component 131 and the mounting groove 132.

[0038] Specifically, such as Figure 7 and Figure 8As shown, regarding the specific configuration of the magnetic adsorption plate 13, in the second embodiment, the first magnetic adsorption element 131 is a magnet; the magnetic adsorption plate 13 has an annular groove 135 on the side facing the back of the portable screen 2. Multiple first magnetic adsorption elements 131 are arranged evenly around the center of the magnetic adsorption plate 13 within the annular groove 135. The even distribution of multiple magnets within the annular groove 135 allows the magnetic adsorption force of the magnetic adsorption plate 13 on the back of the portable screen 2 to be more evenly distributed, preventing the portable screen 2 from tilting or falling off due to excessively strong or weak local adsorption force, thus improving the stability of the portable screen 2. The annular groove 135 also facilitates the installation and positioning of the first magnetic adsorption elements 131.

[0039] Specifically, in the second embodiment, the first magnetic adsorption element 131 is fan-shaped, and the magnetic poles of adjacent first magnetic adsorption elements 131 are arranged in opposite directions. The arrangement of opposite magnetic poles makes the magnetic force distribution more reasonable, and can more accurately guide the portable screen 2 to be aligned when installing it, so as to achieve fast and accurate installation.

[0040] In the second embodiment, as Figure 8 and Figure 9As shown, a central boss 136 is formed by a protrusion in the central area of ​​the magnetic adsorption plate 13. An annular magnetic metal base 137 is installed in the annular groove 135, and the first magnetic adsorption component 131 is installed on the annular magnetic metal base 137. The inner side of the annular magnetic metal base 137 extends from the annular groove 135 to the central boss 136. A central protrusion 1361 is provided on the central boss 136, and the central protrusion 1361 is nested in the central opening 1371 of the annular magnetic metal base 137. A limiting sub-protrusion 13611 is provided on the edge of the central protrusion 1361, and a limiting groove 13711 is opened on the edge of the central opening 1371, and the limiting sub-protrusion 13611 is embedded in the limiting groove 13711. The engagement of the limiting protrusion 13611 and the limiting groove 13711 creates a tight connection between the central protrusion 1361 and the annular magnetic metal base 137, further enhancing the overall structural stability of the magnetic adsorption plate 13 and thus improving the adsorption stability of the portable screen 2. More specifically, the combination of the central protrusion 136 and the annular base, as well as the engagement of the limiting protrusion 13611 and the limiting groove 13711, makes the magnetic adsorption plate 13 more structurally stable when bearing the weight of the portable screen 2, and less prone to deformation or damage. The first magnetic adsorption component 131 is mounted on the annular magnetic metal base 137, which serves as a carrier integrating all the first magnetic adsorption components 131. All the first magnetic adsorption components 131 are then mounted in the magnetic adsorption plate 13 via the annular magnetic metal base 137. Specifically, the annular magnetic metal base 137 can be fixedly mounted on the first magnetic adsorption component 131 using glue or screws. The ring-shaped magnetic metal chassis 137 is made of iron.

[0041] On the other hand, such as Figure 1 and Figure 2 As shown, the other end of the support arm 12 is rotatably connected to the base 11. This rotatable connection between the support arm 12 and the base 11, and the aforementioned rotatable connection between the rotating connector 14 and the other end of the support arm 12, allows the magnetic adsorption plate 13 to be adjusted at multiple angles relative to the base 11 and the support arm 12. Users can adjust the viewing angle of the portable screen 2 as needed to meet usage requirements in different scenarios. The rotatable connection between one end of the support arm 12 and the base 11, and the rotatable connection between the rotating connector 14 and the support arm 12, can both be achieved through a damping pivot, which will not be detailed here. The rotating connector 14 can be mounted on the magnetic adsorption plate 13 using screws.

[0042] like Figures 1 to 3 , Figure 7As shown, this utility model also discloses a display, including the aforementioned magnetic bracket 1 and portable screen 2; the back of the portable screen 2 has a magnetic adsorption area 21; in use, the first magnetic adsorption member 131 is magnetically attracted to the magnetic adsorption area 21 on the back of the portable screen 2, so that the portable screen 2 is used on the magnetically fixed first magnetic adsorption member 131.

[0043] The display of this invention uses a magnetic adsorption area 21 on the portable screen 2 to magnetically attract the first magnetic adsorption component 131, so that the portable screen 2 is magnetically fixed to the first magnetic adsorption component 131 when in use. Thus, when in use, the portable screen 2 can be connected and installed through the magnetic attraction between the first magnetic adsorption component 131 and the magnetic adsorption area 21. The portable screen 2 is installed and used through the magnetic adsorption plate 13, which not only makes assembly convenient during use, but also makes disassembly very convenient when storage, movement, and transportation are required.

[0044] Specifically, such as Figure 5 and Figure 6 As shown, or as Figure 10 As shown, the portable screen 2 includes a housing 22 and an inner frame plate 23. The inner frame plate 23 is installed in the housing 22. A limiting hole 231 is formed on the inner frame plate 23, and a second magnetic adsorption member 24 is provided in the limiting hole 231 to form a magnetic adsorption area 21. The second magnetic adsorption member 24 is a magnet. On the side of the inner frame plate 23 opposite to the back of the portable screen 2, a ring magnetic metal member 25 is provided corresponding to the second magnetic adsorption member 24. The second magnetic adsorption member 24 is adsorbed onto the ring magnetic metal member 25.

[0045] The second magnetic adsorption component 24 is a magnet, and it is adsorbed and fixed by the annular magnetic metal component 25, which can enhance the adsorption effect and the fixing effect of the second magnetic adsorption component 24. Multiple limiting holes 231 are arranged around the circumference, so that the second magnetic adsorption component 24 is evenly distributed on the inner frame plate 23, forming multi-point adsorption with the first magnetic adsorption component 131 of the magnetic bracket 1. The magnetic force distribution is more uniform, avoiding the portable screen 2 from tilting or falling off due to uneven local adsorption force.

[0046] The limiting hole 231 on the inner frame plate 23 is not only used to install the second magnetic adsorption component 24, but also serves as a limiting function to prevent the magnet from shifting or loosening during use, thus improving the stability of the internal structure of the portable screen 2. The annular magnetic metal component 25 provides additional support and fixation for the second magnetic adsorption component 24, allowing the magnet to be firmly adsorbed onto the inner frame plate 23, enhancing the overall structural robustness. The inner frame plate 23 can be installed in the housing 22 using screws.
