Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic shielding technology, specifically relating to a shielding cover for portable electronic devices. Background Technology

[0002] The shielding cover can block external electromagnetic radiation (such as radio waves, static electricity, etc.) from entering the equipment, protect sensitive components (such as chips and sensors) from interference, and ensure stable operation of the equipment.

[0003] Shielding covers are typically made of highly conductive metals (such as copper, aluminum, or iron alloys). They form a Faraday cage effect through grounding, which reflects or absorbs electromagnetic waves. The design must be based on the equipment requirements to select either a fully enclosed or partially covered form.

[0004] For example, in the prior art, Chinese utility model patent CN209402960U discloses a "shielding cover and electronic device". The shielding cover includes a magnetically conductive frame and a cover, with the cover fitting over the magnetically conductive frame.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-4 The present invention provides the following technical solution: a portable electronic device shielding cover, comprising an electronic device shielding cover body composed of a bottom shielding frame 1, a middle shielding frame 2 and a shielding cover 3 stacked together, and further comprising: a flip cover 4 and a locking mechanism 6, wherein the locking mechanism 6 comprises: a limiting block 61, a threaded post 62 and a wing nut 63.

[0040] Furthermore, by Figure 1 and Figure 2 As shown, in this embodiment, an inspection window 31 is machined on the shielding cover 3. The flip cover 4 is hinged to the top surface of the shielding cover 3 at the position corresponding to the inspection window 31. After the flip cover 4 is closed, it is locked by the locking mechanism 6. The limiting block 61 is fixed to the free end of the flip cover 4, and a notch 611 is machined on the limiting block 61. The threaded post 62 is fixed to the top surface of the shielding cover 3 and passes through the notch 611. The wing nut 63 is installed on the protruding end of the threaded post 62 by thread engagement. With the above scheme, in use, first fix the bottom shielding frame 1 to the fixed object and surround the electronic components, then install the middle shielding frame 2 on the top of the bottom shielding frame 1, and finally put the shielding cover on top. The bottom shielding frame 1, the middle shielding frame 2, and the shielding cover 3 are stacked and combined to form the main body of the electronic equipment shielding cover, which provides electromagnetic shielding for the electronic equipment. When necessary, the wing nut 63 is unscrewed and the flip cover 4 is opened to facilitate the maintenance of electronic components through the inspection window 31. This utility model sets an inspection window 31 on the shielding cover 3 and hinges the flip cover 4 on the top surface of the shielding cover 3. The shielding function can be achieved by closing the flip cover 4. After opening the flip cover 4, the electronic components can be maintained through the inspection window 31 without removing the entire shielding cover 3. This is safer and more convenient, extends the service life of the shielding cover, and ensures better shielding effect.

[0041] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, it also includes a handle 5, which is fixed to the top surface of the flip cover 4. With the above solution, the flip cover 4 can be opened easily by the handle 5 during use, and the shielding cover can also be carried and transported easily.

[0042] Preferably, by Figure 1 and Figure 2As shown, in this embodiment, it also includes a conductive rubber ring 41, which is bonded and fixed to the bottom surface of the flip cover 4. With the above solution, when in use, the conductive rubber ring 41 has better flexibility. After the flip cover 4 is closed and locked, the conductive rubber ring 41 shrinks, which improves the sealing performance of the flip cover 4 after it is closed. On the other hand, the conductive rubber ring 41 has a conductive function, which further improves the electromagnetic shielding effect.

[0043] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, it also includes: double-sided adhesive tape 7, which is bonded and fixed to the bottom surface of the bottom shielding frame 1. The bottom shielding frame 1 is bonded and fixed to the fixing object by the double-sided adhesive tape 7, which is convenient to fix, has high stability, and allows for free selection of the installation position of the bottom shielding frame 1.

[0044] Optionally, by Figure 1 and Figure 3 As shown, this embodiment also includes: a first magnetic block 11 and a first magnetic piece 22. Four first magnetic blocks 11 are fixed diagonally at the four corners of the top surface of the bottom shielding frame 1. The four corners of the bottom surface of the middle shielding frame 2 are machined with first positioning grooves 21 for the first magnetic blocks 11 to be embedded. The first magnetic piece 22 is glued and fixed in the first positioning groove 21 and attracts the first magnetic block 11. With the above scheme, when installing the middle shielding frame 2, the first magnetic block 11 is embedded in the corresponding first positioning groove 21. At this time, the first magnetic piece 22 attracts the first magnetic block 11, and the stable installation of the middle shielding frame 2 can be completed.

[0045] Optionally, by Figure 1 and Figure 3 As shown, this embodiment also includes: a second magnetic block 23 and a second magnetic piece 33. Four second magnetic blocks 23 are fixed diagonally at the four corners of the top surface of the middle shielding frame 2. The four corners of the bottom surface of the shielding cover 3 are machined with second positioning grooves 32 for the second magnetic blocks 23 to be embedded. The second magnetic pieces 33 are glued and fixed in the second positioning grooves 32 and attract the second magnetic blocks 23. With the above scheme, when installing the shielding cover 3, the second magnetic blocks 23 are embedded in the corresponding second positioning grooves 32. At this time, the second magnetic pieces 33 attract the second magnetic blocks 23, and the stable installation of the shielding cover 3 can be completed.

[0046] Preferably, by Figure 1 and Figure 4 As shown in this embodiment, a breathable micropore 24 is processed on the middle shielding frame 2. After adopting the above solution, the breathable micropore 24 facilitates the ventilation and heat dissipation of electronic components during use.

[0047] It should be noted that the breathable micropores 24 are not arbitrarily designed pore structures, but rather optimized designs based on actual electromagnetic shielding requirements. The number, diameter, and placement of the breathable micropores 24 must meet electromagnetic shielding requirements to avoid affecting the electromagnetic shielding effect.

[0048] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes: copper foil 8, which is bonded and fixed to the outer wall of the middle shielding frame 2 at the position corresponding to the ventilating micropore 24. After adopting the above solution, if the electromagnetic shielding requirement of the electronic components is greater than the heat dissipation requirement during actual use, the copper foil 8 can be bonded and fixed to the outer wall of the middle shielding frame 2 and cover the ventilating micropore 24, so that the shielding cover is in a fully enclosed state, ensuring a better electromagnetic shielding effect.

[0049] Components not described in detail in this article are existing technologies.

[0050] The working principle and usage process of this utility model: When using the portable electronic device shielding cover of this utility model, first fix the bottom shielding frame 1 on the fixed object and surround the electronic components, then install the middle shielding frame 2 on the top of the bottom shielding frame 1, and finally install the shielding cover 3 on the top of the middle shielding frame 2. The bottom shielding frame 1, the middle shielding frame 2 and the shielding cover 3 are stacked and combined to form the main body of the electronic device shielding cover, which provides electromagnetic shielding for the electronic device.

[0051] If necessary, unscrew the wing nut 63 and open the flip cover 4 to facilitate the inspection of electronic components through the inspection window 31;

[0052] This utility model provides a maintenance window 31 on the shielding cover 3 and a flip cover 4 hinged to the top surface of the shielding cover 3. The shielding function can be achieved by closing the flip cover 4. After opening the flip cover 4, the electronic components can be inspected through the maintenance window 31 without removing the entire shielding cover 3. This is safer and more convenient, extends the service life of the shielding cover, and ensures the best shielding effect.

[0053] In another aspect of this invention, the ventilation micropores 24 facilitate ventilation and heat dissipation for electronic components.

[0054] In addition, if the electromagnetic shielding requirement of electronic components is greater than the heat dissipation requirement in actual use, the copper foil 8 can be bonded and fixed to the outer wall of the middle shielding frame 2 and covered with the breathable micropores 24 to make the shielding cover fully enclosed and ensure better electromagnetic shielding effect.
