Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a schematic diagram illustrating a shielding module according to an exemplary embodiment. Referring to fig. 1, the shielding module 100 includes:

a first shield case 110 having a first opening;

a shield layer 120 comprising:

a first region 121 welded to an edge of the first opening of first shield shell 110;

a second region 122 covering the first opening; wherein the area of the second region is greater than or equal to the area of the first opening.

For example, the first shield case may include: a rigid housing. The material from which first shield shell 110 is made may include: metallic materials, alloy materials, and the like. For example, first shield shell 110 may be made of copper, stainless steel, or an aluminum magnesium alloy, or the like.

For example, the material of which the shielding layer 120 is made may include: metallic materials, alloy materials, and the like. For example, the shield layer may be made of copper foil, aluminum sheet, or aluminum-copper alloy layer, etc.

For example, the first region of the shielding layer may be soldered to a side of the first shielding shell facing the shielded device, or may be soldered to a side of the first shielding shell facing away from the shielded device.

For example, the second region of the shielding layer may include: a flexible region.

When the part of the shielded device in the first shielding shell is positioned outside the first shielding shell through the first opening, the flexible area can be deformed and covers the surface of the shielded device positioned outside the first shielding shell, and the shielding effect of the shielded device is ensured.

When the heights of the shielded devices positioned outside the first shielding shell are different, the flexible shielding layer can be attached to the surface of the shielded devices. When the shielding effect is ensured, compared with the arrangement of the shielding layer with the same height, the embodiment of the disclosure reduces the occupation of the internal space of the mobile terminal.

When the height of the shielded device arranged at the first opening of the first shielding shell is lower than that of the first shielding shell, the flexible region can deform under the extrusion of other devices outside the first shielding shell and is sunken into the first shielding shell at the first opening, so that the layout influence of the first shielding shell on other devices inside the mobile terminal is reduced, and the available space inside the mobile terminal is increased.

For example, in the embodiment of the present disclosure, the first region of the shielding layer may be soldered to the first shielding shell by using a metal such as tin.

Referring to fig. 2, when the shielding layer is separated from the first shielding shell, the first surface of the first shielding shell 110 has a first opening 111, and a shielded device 200 is disposed in a range covered by the first shielding shell.

For example, when the shielding layer is welded on the first shielding shell in fig. 2, the whole edge area of one side of the shielding layer can be welded with the edge of one side of the first opening, so as to form the shielding module shown in fig. 1.

For example, when the shielding layer is welded on the first shielding shell in fig. 2, a partial edge area on one side of the shielding layer may be welded with an edge area on one side of the first opening to form the shielding module shown in fig. 3.

Compared with the method that the shielding layer is adhered to the first shielding shell by using glue, the embodiment of the disclosure utilizes the metal solder to weld the first area of the shielding layer on the edge of one side of the first opening, so that a tight metal welding area is formed between the shielding layer and the first shielding shell, and the shielding effect is ensured.

Along with the service time, the fixing effect of glue between the shielding layer and the first shielding shell is weakened, the stability of metal welding is high, and the probability that the shielding cover is separated from the first shielding shell is reduced.

In some embodiments, referring to fig. 4 to 7, the shielding module 100 includes:

a second shielding shell 130 located inside the first shielding shell 120 and having one or more second openings;

the first opening 111 is aligned with at least one second opening.

Fig. 5 is a schematic illustration of a second shielding shell according to an exemplary embodiment. Referring to fig. 5, the second shielding shell has three second openings. Fig. 6 is a schematic view of first shield shell 110 according to an exemplary embodiment, and fig. 7 is a schematic view illustrating a structure in which shield layer 120 is welded to first shield shell 110 in fig. 6; the first shielding housing 110 in fig. 7 is snapped with the second shielding housing 130 in fig. 5 to form the shielding module 100.

In some embodiments, as shown in fig. 4 to 7, when the height of the shielded device 200 is greater than the first height, the shielded device 200 extends out of the first shielding shell through the first second opening and the first opening. The second opening provides access to the second shield shell for an adhesive used to secure the shielded device. The third second opening serves as a heat dissipation channel for the shielded device. At this time, as shown in fig. 6, the first opening 111 of the first shielding shell is aligned with the first second opening, the size of the first opening may be smaller than or equal to the size of the first second opening, and the size of the first opening can allow the shielded device with a height greater than the first height to protrude out of the first shielding shell.

In some embodiments, as shown in fig. 8, when two shielded devices having a height greater than the first height are included in the second shielding shell, the first shielded device protrudes out of the first shielding shell through the first second opening and the first opening; the second shielded device extends out of the first shielding shell through the second opening and the first opening; the third second opening serves as a heat dissipation channel for the shielded device. At this time, as shown in fig. 9, the first opening is aligned with the three second openings, and the size of the first opening may be larger than the sum of the sizes of the three second openings.

In some embodiments, when the height of the shielded device 200 is greater than the first height, the shielded device protrudes out of the first shielding shell through the second opening and the first opening, and at least part of the shielded device is located outside the first shielding shell;

and a second region covering the shielded device outside the first shield case.

For example, the first height may be set according to the size requirement of the shielding module or the shielding module. For example, the first height may be set to be equal to a mode of heights of all the shielded devices, and a difference between the height of the second shielding housing and the mode may be set to be a predetermined height difference (e.g., 1mm) so as to reduce a space between the second shielding housing and the shielded devices having a height less than or equal to the first height, thereby reducing an internal space of the mobile terminal occupied by the shielding module.

In the embodiment of the present disclosure, as shown in fig. 5, when the height of the shielded device 200 is greater than the first height, compared to setting the height of the second shielding shell or the first shielding shell to be greater than the heights of all the shielded devices, the shielded device with the height greater than the first height in the embodiment of the present disclosure passes through the second opening and the first opening and protrudes out of the first shielding shell, so that a partial area of the shielded device is located outside the second shielding shell and the first shielding shell, thereby reducing the occupation of the internal space of the mobile terminal by the shielding module.

Illustratively, when the shielded device is at least partially located outside the first shielding shell, the shielded device is in contact with the second area, so that the second area is expanded to enlarge the spatial range covered by the second area. Wherein, the space covered by the second area after expansion can accommodate the shielded device outside the first shielding shell.

When other elements in the mobile terminal are in contact with the shielding layer, the second area of the shielding layer can be subjected to form change based on the form of the other elements, and the influence on the layout of the other elements is reduced.

When the height of the shielded device is higher, compared with the arrangement of the first shielding shell and/or the second shielding shell which are the same as the height of the shielded device, the embodiment of the disclosure reduces the height of the shielding module, reduces the occupation of the shielding module on the internal space of the mobile terminal, and reduces the influence on the layout of other elements in the mobile terminal.

In some embodiments, second opening 131 also serves as a passage for adhesive to and from the second shielding shell; wherein the adhesive is used to secure the shielded device.

For example, a user may input an adhesive into the second shielding housing through the second opening, so as to enhance the firmness between the shielded device and the board body for supporting the shielded device in the second shielding housing, and improve the stability between the shielded device and the shielding module.

Through setting up the second opening in the embodiment of this disclosure, provide convenient for the user to carry out the fixed operation to the shielded device in first shielded shell.

In some embodiments, the second opening is also used as a heat sink channel for the shielded device.

By providing the second opening, the heat dissipation space of the shielded device is increased, which is beneficial for dissipating heat of the shielded device. The user can also set up radiator unit such as heat dissipation glue, heat dissipation pad in first shielding shell through the second opening for shielded device line radiating speed.

In some embodiments, the first shielding shell further comprises:

and the bayonet is used for clamping the first shielding shell and the second shielding shell.

In the embodiment of the disclosure, as shown in fig. 7, bayonets are arranged around the first shielding shell for fixing the first shielding shell and the second shielding shell, so that the connection stability between the first shielding shell and the second shielding shell is increased, the probability of separation of the first shielding shell and the second shielding shell is reduced, the shielding effect is ensured, and the improvement of user experience is facilitated.

In some embodiments, when the first shielding shell comprises a plurality of bayonets, the plurality of bayonets are symmetrically distributed at an edge of the first shielding shell.

Referring to fig. 7, the first surface of the first shielding shell is square, and the first surface of the first shielding shell has four bayonets, which are located at four vertices of the square first surface.

In the embodiment of the present disclosure, through set up a plurality of bayonets on first shield shell to set up the bayonet socket symmetry at first shield shell's edge, can make the fixed between first shield shell and the second shield shell more inseparable, improve shielding effect, help promoting user experience.

In some embodiments, the shielding module comprises:

the heat dissipation layer is positioned on the first surface of the shielding layer; the first surface is a surface of the shielding layer facing the inside of the first shielding shell through the first opening.

In an embodiment of the present disclosure, referring to fig. 10, when a distance between the first opening and the side wall of the first shielding case is smaller than a distance threshold, a portion of the edge of the first opening is located close to the side wall of the first shielding case. Wherein, the distance threshold value can be set according to actual requirements.

Referring to fig. 11 and 12, in order to ensure the shielding effect of the shielding layer on the first opening, the second region of the shielding layer is in a bent state, the first end of the first region is welded on the side wall of the first shielding shell, and the second end of the first region is welded on the second surface of the first shielding shell. Here, the sidewall is a sidewall whose distance from the first opening is less than a distance threshold.

In the embodiment of the disclosure, the shielding effect of the first opening is ensured by arranging the shielding layer in the bent state.

In some embodiments, the shield layer is a flexible shield layer that is capable of being bent.

Illustratively, the shielding layer may be made of a material having flexibility. For example, the shielding layer may be made of copper, aluminum, or the like.

And the flexible shielding layer plays a role in buffering, and the partial area of the shielded device positioned outside the first shielding shell can be reduced from pressing other elements outside the first shielding shell. When the internal space of the mobile terminal is limited, the flexible shielding layer may reduce the strength influence on other elements.

In the embodiment of the disclosure, through the flexible shielding layer which is arranged and can be bent, the attaching degree between the shielding layer and the shielded device can be improved, and the occupation of the shielding module on the internal space of the mobile terminal is reduced.
