[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1

[0034] Please see Figures 1 to 10 An electromagnetic shielding structure based on aluminum foam composite board includes: a first aluminum foam board 1 and a second aluminum foam board 2;

[0035] Thin aluminum plates 3 are set on the outer walls of the first foamed aluminum plate 1 and the second foamed aluminum plate 2. The bottom of the second foamed aluminum plate 2 is provided with a first L-shaped groove 4. An inclined strip plate 5 is fixedly installed on one side of the first L-shaped groove 4. A strip groove 8 is provided on the top of the inclined strip plate 5.

[0036] A second L-shaped groove 6 is formed on one side of the first foamed aluminum sheet 1. A slot 7 is formed on the inner wall of the second L-shaped groove 6. The inclined strip 5 is inserted into the slot 7. Multiple first springs 9 are fixedly installed on the inner top wall of the first L-shaped groove 4 through the opening of the mounting groove. The bottom end of the multiple first springs 9 is fixedly connected to the strip plate 10. The strip plate 10 is inserted into the strip groove 8.

[0037] The present invention provides a technical solution in which the first L-shaped groove 4 and the second L-shaped groove 6 facilitate the splicing of the first aluminum foam sheet 1 and the second aluminum foam sheet 2. During installation, the inclined strip 5 is inserted into the slot 7. Simultaneously, the inclined strip 5 presses against the strip 10, causing the first spring 9 to contract and slide the strip 10 into the mounting groove. When the strip 10 is above the inclined strip 5, the first spring 9 causes the strip 10 to return to its original position, allowing it to be inserted into the slot 8 for positioning and fixation. This achieves the goal of lightweight construction, significantly reducing weight while maintaining shielding effectiveness, and facilitating installation. Advanced welding techniques (such as laser welding and argon arc welding) are used to weld the corners between the thin aluminum plates 3. This method avoids the difficulty of welding aluminum foam itself while meeting the sealing requirements of electromagnetic shielding.

[0038] Further, two through grooves 12 are oppositely arranged on one side of the second aluminum foam plate 2, and a plurality of second springs 13 are fixedly installed on inner top walls of the two through grooves 12, the top of the strip-shaped plate 10 oppositely has two L-shaped plates 14 fixedly installed, the two L-shaped plates 14 are slidably connected between the two through grooves 12, the bottom ends of the plurality of second springs 13 are connected with the two L-shaped plates 14, and the front sides of the two L-shaped plates 14 have a handle 15 fixedly installed, and an anti-skid sleeve 16 is sleeved on the outer side wall of the handle 15.

[0039] Specifically, when the first aluminum foam plate 1 and the second aluminum foam plate 2 need to be disassembled, the handle 15 is gripped and pulled upward, so that the L-shaped plate 14 slides in the through groove 12, the second spring 13 is contracted, and the strip-shaped plate 10 is separated from the strip-shaped groove 8, at this time, the first aluminum foam plate 1 and the second aluminum foam plate 2 can be disassembled, and the anti-skid sleeve 16 on the handle 15 is used to prevent slipping when the handle 15 is gripped.

[0041] Based on the embodiment one, in the embodiment, the protection mechanism 11 is arranged on the outer side wall of the thin aluminum plate 3, the protection mechanism 11 comprises a corrosion-resistant coating 110 coated on the outer side wall of the thin aluminum plate 3, and the corrosion-resistant coating 110 is specifically an epoxy resin coating, and a rust-proof coating 111 is coated on the outer side wall of the thin aluminum plate 3 away from the corrosion-resistant coating 110, and the rust-proof coating 111 is specifically rust-proof paint.

[0042] The technical scheme provided in the embodiment is that the corrosion-resistant coating 110 and the rust-proof coating 111 are used to isolate the corrosion medium in the outside world, such as moisture, oxygen and ions, so as to prevent the thin aluminum plate 3 from being corroded and prolong the service life.

[0043] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection range of the utility model.
