[0002] Electromagnetic shielding is a technology that needs to be solved in many electromechanical devices, especially in areas with relatively high requirements for electromagnetic shielding. The traditional shielding method in electromechanical equipment is to set conductive foam at the door and window switches of the electromechanical equipment. When the equipment is closed, the conductive foam contacts the metal of the electromechanical equipment to achieve the shielding effect. The surface of the electromechanical equipment in contact with the conductive foam must be metal, and a non-conductive layer cannot be sprayed. In addition, this shielding structure requires tight contact, which results in doors and windows requiring greater mechanical pressure for opening and closing operations, and the shielding effect is affected by whether the doors and windows are closed tightly.

[0003] Therefore, the shielding effect of the electromagnetic shielding structure of the electromechanical equipment in the prior art is unstable, and it is difficult to open the doors and windows of the electromechanical equipment, and the requirements for closing the doors and windows are high.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] like Figure 1 As shown, the present invention provides a shielding structure, which specifically includes a first shielding wing 1, a conductive foam 3 and a second shielding wing 2, wherein the first shielding wing 1 and the second shielding wing 2 are both circumferentially formed between an opening gap 5 of an inner shielding space 4 toward the outside, the second shielding wing 2 is arranged on a side of the inner shielding space 4 relative to the first shielding wing 1, and the conductive foam 3 is arranged between the first shielding wing 1 and the second shielding wing 2;

[0033] The inner surface of one side of the first shielding wing 1 is at least partially attached to one side of the conductive foam 3, and the end of the other side of the first shielding wing 1 is sealed with the inner shielding space 4;

[0034] The outer surface of one side of the second shielding wing 2 is at least partially attached to the other side of the conductive foam 3 , and the end of the other side of the second shielding wing 2 is sealed with the inner shielding space 4 .

[0035] In the shielding structure provided by the present invention, the inner shielding space 4 mainly refers to the inner enclosed space of the electromechanical equipment. After the inner shielding space 4 is closed to the external opening gap 5, the first shielding wing 1 and the second shielding wing 2 are synchronously slid laterally closed, which greatly reduces the opening and closing resistance. The conductive foam 3 is then closed and located between the first shielding wing 1 and the second shielding wing 2. The first shielding wing 1 and the second shielding wing 2 are respectively attached to the two sides of the conductive foam 3 to form an internal shielding space, which effectively shields external electromagnetic signals.

[0036] During use, in order to facilitate the closing action of the opening gap 5 of the inner shielding space 4 to the outside, and facilitate the fitting and insertion action between the conductive foam 3 and the first shielding wing 1 and the second shielding wing 2, the conductive foam 3 can be selected to have a rounded corner structure or a chamfered corner structure, and the second shielding wing 2 can also be selected to have a rounded corner structure or a chamfered corner structure. There are 8 specific embodiments, which are divided into 4 overviews:

[0037] Case 1: the side where the second shielding wing 2 is in contact with the conductive foam 3 is configured as a chamfered arc surface or a rounded arc surface bent toward the other side, and the side where the conductive foam 3 is in contact with the second shielding wing 2 is a conventional structure.

[0038] Case 2: the side where the conductive foam 3 is bonded to the second shielding wing 2 is configured as a chamfered arc surface or a rounded arc surface bent toward the other side, and the side where the second shielding wing 2 is bonded to the conductive foam 3 is a conventional structure.

[0039] Case 3: the side of the second shielding wing 2 that is in contact with the conductive foam 3 is configured as a chamfered arc surface that is bent toward the other side, and the side of the conductive foam 3 that is in contact with the second shielding wing 2 is a chamfered arc surface or a rounded arc surface.

[0040] Case 4: the side of the second shielding wing 2 that is in contact with the conductive foam 3 is configured as a rounded arc surface that is bent toward the other side, and the side of the conductive foam 3 that is in contact with the second shielding wing 2 is a chamfered arc surface or a rounded arc surface.

[0041] In a specific embodiment, the first shielding wing 1 and the second shielding wing 2 are both made of metal, and other materials with shielding effects may also be selected.

[0042] Embodiment 2:

[0043] On the basis of Example 1, Figure 2As shown, a third shielding wing 6 is provided on a side of the second shielding wing 2 close to the inner shielding space 4, and the third shielding wing 6 and the second shielding wing 2 are respectively sealed at opposite sides with respect to the inner shielding space 4.

[0044] The positions of the first shielding wing 1, the second shielding wing 2 and the third shielding wing 6 at the opening gap 5 are staggered, and the third shielding wing 6 and the first shielding wing 1 are respectively on the same side as the positions sealed with the inner shielding space 4; after the opening gap 5 is closed, the first shielding wing 1, the second shielding wing 2 and the third shielding wing 6 form a meander structure to weaken the electromagnetic signal, and combined with the sealing performance of the conductive foam 3, the effective shielding of the internal space is further improved.

[0045] In a specific embodiment, the third shielding wing 6 is made of metal material, and other materials with shielding effect can also be selected.

[0046] Embodiment 3:

[0047] Based on Example 1, Figure 3 As shown, the present invention provides a cabinet electronic device, comprising a cabinet 7 and a door 8, wherein the shielding structure is arranged at the closed connection between the cabinet 7 and the door 8; wherein one end of the first shielding wing 1 is sealed and connected to the cabinet 7, and one end of the second shielding wing 2 is sealed and connected to the door 8. In order to facilitate the switching action, the end of the second shielding wing 2 where it is attached to the conductive foam 3 can be selected to have a rounded arc surface or a chamfered arc surface.

[0048] In a specific embodiment, the end of the conductive foam 3 is fixedly connected to the cabinet 7 .

[0049] In the closing action of the cabinet 7 and the door 8 of the cabinet electronic device, because the shielding structure is a lateral sliding design, the resistance of the opening and closing action process is reduced, and the shielding structure provided by the present invention is more labor-saving. When the cabinet 7 and the door 8 are closed, the conductive foam 3 is located between the first shielding wing 1 and the second shielding wing 2, the inner surface of one side of the first shielding wing 1 is at least partially attached to one side of the conductive foam 3, and the outer surface of one side of the second shielding wing 2 is at least partially attached to the other side of the conductive foam 3. The conductive foam 3, the first shielding wing 1 and the second shielding wing 2 form a shielding structure, which realizes effective electromagnetic shielding of the cabinet electronic device. The obvious gap between the first shielding wing, the second shielding wing and the third shielding wing and the door or cabinet in the figure is to reflect the passage path of the electromagnetic signal and its specific installation position. In practice, the gap is very small (that is, the gap between the door and the cabinet is very small).

[0050] Embodiment 4:

[0051] Based on Example 2, Figure 4 and Figure 5As shown, the present invention provides a cabinet electronic device, comprising a cabinet 7 and a door 8, wherein the shielding structure is arranged at the closed connection between the cabinet 7 and the door 8. Among them, one end of the first shielding wing 1 is sealed and connected to the cabinet 7, one end of the second shielding wing 2 is sealed and connected to the door 8, one end of the third shielding wing 6 is sealed and connected to the door 8, and the end of the conductive foam 3 is fixedly connected to the cabinet 7. The positions of the first shielding wing 1, the second shielding wing 2 and the third shielding wing 6 at the closed connection of the cabinet electronic device are arranged in a staggered relationship.

[0052] When the cabinet 7 and the door 8 are closed, the conductive foam 3 is located between the first shielding wing 1 and the second shielding wing 2, and its two sides are respectively attached to the first shielding wing 1 and the second shielding wing 2. The first shielding wing 1, the second shielding wing 2 and the third shielding wing 6 form a meander structure to further weaken the electromagnetic signal. Combined with the conductive foam 3, the shielding effect of the electronic equipment inside the cabinet is improved as a whole. The obvious gap between the first shielding wing, the second shielding wing and the third shielding wing and the door or cabinet in the figure is to reflect the passage path of the electromagnetic signal and its specific installation position. In practice, the gap is very small (that is, the gap between the door and the cabinet is very small).

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
