The technical scheme of the application provides electronic equipment, and the electronic equipment can include waiting shield spare, ground structure spare, shield spare and bearing structure. The to-be-shielded part is arranged on one side of the grounding structural part. The grounding structural member is provided with a via hole which penetrates through the grounding structural member and can be penetrated by the shielding member. When specifically setting up the shield, the shield has first insulating material layer and the conducting material layer of looks range upon range of setting, and the shield passes through first insulating material layer and laminates mutually with the ground structure. In order to enable the shielding element to absorb the electrical signal radiated by the element to be shielded, a part of the shielding element may be disposed on a side of the grounding structure element close to the element to be shielded, and another part of the shielding element may pass through the via hole of the grounding structure element and then be fixed to the grounding structure element. In addition, one side of the conductive material layer facing the grounding structural member can be divided into a conductive region and an insulating region, so that the first insulating material layer is only arranged in the insulating region, and signal interference generated by the to-be-shielded member due to large-area contact of the conductive material layer and the grounding structural member is avoided. The conductive area of the conductive material layer is attached to the grounding structural member under the supporting effect of the supporting structure, so that the shielding member is grounded and conducted with the grounding structural member.

By adopting the scheme, the electric signal radiated by the shield can be absorbed by the conductive material layer of the shield, and the conductive material layer of the shield is tightly attached to the grounding structural member, so that the electric signal absorbed by the conductive material layer is grounded through the grounding structural member, the shield is grounded and conducted with the grounding structural member, and the shield of the shield is further realized. In addition, in the scheme, the part of the shielding piece corresponding to the conductive region is supported by the supporting structure, so that the contact reliability between the conductive material layer and the grounding structural piece can be effectively improved, and the stability of the shielding effect of the shielding piece to be treated is favorably improved.

In one possible implementation manner of the present application, when the shielding element is specifically arranged, the shielding element may pass through a portion of the via hole of the grounding structural element, and be attached to one side of the grounding structural element, which is far away from the to-be-shielded element, after being bent. The conductive area can then be arranged at that part of the grounding structure which is fastened to the side of the shielding element remote from the element to be shielded, and optionally at the end of that part of the shielding element.

In one possible implementation manner of the present application, the electronic device may further include a pressing structure, which may be, but is not limited to, a printed circuit board, a battery holder, or a rear case of the electronic device.

At this time, one end of the supporting structure can be fixed on one side of the grounding structural member close to the to-be-shielded member; or, one end of the supporting structure is fixed on one side of the grounding structural part far away from the to-be-shielded part. The reasonable layout can be carried out on each structure in the electronic equipment, and the utilization rate of the internal space of the electronic equipment is improved.

Detailed Description

For the convenience of understanding the electronic device provided in the embodiments of the present application, a specific application scenario thereof is first described below. The electronic device of the embodiment of the application can be but not limited to a mobile phone, a tablet computer, an intelligent wearable device, a Personal Digital Assistant (PDA) and other electronic devices which need signal shielding. At present, in order to comply with the development requirement of the large screen occupation ratio of the electronic device, manufacturers of the electronic devices generally adopt a mode of designing a frame of the electronic device to be smaller and smaller to increase the screen occupation ratio so as to meet the visual perception of users. The antenna of the electronic device is usually disposed at the frame, and when the frame of the electronic device is reduced, the clearance area of the antenna is also reduced, which may cause the interference generated by the electronic device in the electronic device to the antenna to be more and more obvious in the process of transmitting the electrical signal. To solve the above problems, shielding of the electronic device is generally required.

There are various shielding schemes for electronic devices, and referring to fig. 1, a shielding scheme for electronic equipment according to an embodiment of the prior art is shown in fig. 1. In this embodiment, the electronic apparatus includes a grounding structural member 1, a shield 2, and a to-be-shielded member 3, which are stacked. The grounding structure member 1 is grounded, the to-be-shielded member 3 can be an electronic device such as a display, a camera or a receiver, and the electronic device can transmit electric signals. The shielding part 2 is arranged between the part 3 to be shielded and the grounding structural part 1, and the electric signals radiated by the part 3 to be shielded can be absorbed by the shielding part 2 and grounded through the grounding structural part 1. In this embodiment, the shielding element 2 includes a conductive material layer 201 and an adhesive layer 202 stacked on each other, and the conductive material layer 201 can be fixed to the grounding structural member 1 through the adhesive layer 202, so that the conductive material layer 201 can be conducted with the grounding structural member 1 through the adhesive layer 202, thereby grounding the conductive material layer 201, and further achieving a shielding effect on the electronic device.

In addition to the above-described structure, the electronic apparatus may further include a second insulating material layer 4, the second insulating material layer 4 being disposed between the member to be shielded 3 and the shielding member 2. Since the to-be-shielded element 3 and the shielding element 2 are usually made of metal materials, by disposing the second insulating material layer 4 therebetween, the to-be-shielded element 3 and the shielding element 2 can be prevented from being in direct contact, and a large signal interference is generated on the to-be-shielded element 3 or the antenna.

In the above structure, when the conductive material layer 201 and the ground structure 1 are conducted through the adhesive layer 202, the conductive performance is achieved by conducting the metal particles because the adhesive layer 202 has the metal particles inside. However, the conduction between the metal particles is unstable, which may have some critical states, thereby causing the shielding of the electronic device by the shielding member 2 in this scheme to be unstable.

In order to realize a stable shielding effect for an electronic device waiting shield 3 in an electronic apparatus, the present application provides an electronic apparatus. Referring to fig. 2, the electronic device of the embodiment of the present application mainly includes: a shield 3 to be shielded, a grounding structure 1, a shield 2, a support structure 5, and a hold-down structure 6. The to-be-shielded component 3 and the compressing structure 6 are disposed on two sides of the grounding structure 1, and the to-be-shielded component 3 may be, but is not limited to, a display, such as a Liquid Crystal Display (LCD). The shielding element 3 may be an electronic device such as a camera or an earphone, which may transmit electrical signals.

When the grounding structure 1 is specifically arranged, the grounding structure 1 may be, but not limited to, a middle frame, a bracket, or the like, so as to support the to-be-shielded element 3 and the grounding structure 1, which are arranged on both sides of the grounding structure 1. In addition, with reference to fig. 2, a via hole 101 is further formed on the grounding structure 1, and the via hole 101 is disposed through the grounding structure 1. The opening position of the via hole 101 can be selected according to the specific shielding requirement of the to-be-shielded element 3, and can be at the edge of the grounding structural element 1 or at the middle. In the embodiments of the present application, parameters such as the cross-sectional shape of the via hole 101 and the size of the via hole 101 are not specifically limited, and may be adjusted according to actual situations.

With continued reference to fig. 2, the shield 2 may comprise a two-layer structure stacked on top of each other, in particular a first layer of insulating material 203 and a layer of conductive material 201 stacked on top of each other. The conductive material layer 201 may be made of a metal capable of conducting an electrical signal, such as copper, aluminum, or silver, and the first insulating material layer 203 may be a layer structure formed by an insulating paste or the like coated or adhered on the conductive material layer 201. In addition, the projection of the first insulating material layer 203 on the conductive material layer 201 may be within the boundary of the conductive material layer 201, specifically, the side of the conductive material layer 201 facing the ground structure member 1 is divided into a conductive region (a region with a length L1 on the conductive material layer 201 in fig. 2) in conductive contact with the ground structure member 1, and an insulating region other than the conductive region, where the first insulating material layer 203 is disposed. To facilitate the positioning of the first insulating material layer 203, the first insulating material layer 203 covering the conductive material layer 201 may be configured such that one end portion of the conductive material layer 201 is exposed as a conductive region, and the conductive region is disposed at the end portion of the conductive material layer.

In order to achieve the shielding effect of the shield 3, referring to fig. 2, the first insulating material layer 203 of the shield 2 may be attached to the grounding structural member 1, so that the contact instability between the conductive material layer 201 and the grounding structural member 1 due to the lack of reliable crimping force can be avoided, and the signal interference between the shield 3 and the antenna can be avoided. In addition, by attaching the first insulating material layer 203 of the shielding element 2 to the grounding structure 1, the conductive material layer 201 can be exposed, so that the conductive material layer 201 of the shielding element 2 can receive the electrical signal radiated by the element 3 to be shielded. When the shielding element 2 is specifically arranged on the grounding structural element 1, a part of the shielding element 2 is arranged on one side of the grounding structural element 1 close to the element 3 to be shielded, and the other part of the shielding element 2 passes through the via hole 101 on the grounding structural element 1 and is attached to one side of the grounding structural element 1 away from the element 3 to be shielded after being bent. The conductive region of the shielding element 2 is disposed on a side of the grounding structure 1 away from the element to be shielded 3. In this embodiment, the area of the part of the grounding structure 1, which is close to the side of the to-be-shielded element 3, where the shielding element 2 is disposed, may be selected according to the shielding requirement of the to-be-shielded element 3.

When the first insulating material layer 203 is an insulating glue, the insulating glue can be adhered to the grounding structural member 1, so as to fix the shielding element 2 to the grounding structural member 1; when the first insulating material layer 203 does not have adhesiveness, an adhesive such as an adhesive paste may be applied between the first insulating material layer 203 and the ground structure member 1 to fix the first insulating material layer 203 and the ground structure member 1. With continued reference to fig. 2, the portion of the shield 2 corresponding to the conductive area of the conductive material layer 201 may be brought into contact with the ground structure 1 by the supporting force of the support structure 5.

In particular when arranging the support structure 5, the support structure 5 may be arranged between the ground structure 1 and the compacting structure 6, see fig. 2. One end of the supporting structure 5 can be fixed on the pressing structure 6 in a bonding or welding mode; the other end of the support structure 5 abuts against the shielding element 2, so that the conductive area of the shielding element 2 is tightly attached to the grounding structure 1. In addition, when the support structure 5 is brought into abutment with the shield 2, the support structure 5 may be brought into direct abutment with the position of the corresponding conductive area of the shield 2. The contact between the support structure 5 and the shield 2 may be a point contact or a surface contact, and is not particularly limited in the embodiment of the present application. Through set up bearing structure 5 between ground connection structure 1 and compact structure 6, can make the conductive region of shield 2 and the inseparable laminating of ground connection structure 1 to can realize conducting material layer 201 and the stable of ground connection structure 1 and switch on, and then realize treating the stable shielding effect of shield 3.

With reference to fig. 2, the supporting structure 5 may be an elastic structure member such as a spring, or silica gel, so that the conductive area of the shielding member 2 is tightly attached to the grounding structure member 1 under the elastic force of the elastic structure member. In some embodiments, the supporting structure 5 may also be a hard supporting structure 5, so as to achieve stable contact between the conductive region of the shielding element 2 and the grounding structure 1 under the condition of a certain distance between the grounding structure 1 and the pressing structure 6, so as to improve the shielding effect on the to-be-shielded element 3.

In addition, the support structure 5 may be a conductive structure, and may also be an insulating structure. When the compressing structure 6 is grounded, the supporting structure 5 can be set as a conductive structure, so that the conductive material layer 201 of the shielding element 2 is conducted with the compressing structure 6 through the supporting structure 5, the shielding element 2 is grounded through the compressing structure 6, and the shielding effect of the shielding element 3 is realized.

Referring to fig. 2, when the compressing structure 6 is specifically disposed, the compressing structure 6 may be a Printed Circuit Board (PCB) of the electronic device, and since a device may be disposed on a side surface of the PCB facing the ground structure 1, a specific size of the supporting structure 5 may be adjusted according to a size of the device on the PCB, so as to avoid an increase in overall thickness of the electronic device while achieving an effect of stably supporting the conductive region of the shielding member 2. In addition, the pressing structure 6 may also be another structure that is disposed in the electronic device and can serve as a support, such as a battery holder (not shown in the figure) or a rear case (not shown in the figure) of the electronic device.

Since signal interference is likely to occur due to contact between two metal materials, the to-be-shielded member 3 and the conductive material layer 201 are usually made of metal materials. Therefore, with reference to fig. 2, in the electronic device according to the embodiment of the present application, a second insulating material layer 4 may be further disposed on a side surface of the to-be-shielded element 3 close to the grounding structure 1, wherein a material of the second insulating material layer 4 may be the same as or different from a material of the first insulating material layer 203 of the shielding element 2. Thereby avoiding direct contact of the shield 3 to the conductive material layer 201 of the shield 2 to reduce signal interference with the shield 3 and the antenna.

In the above embodiments of the present application, the conductive material layer 201 of the shielding element 2 is closely attached to the grounding structural element 1, and the electric signal, which is absorbed by the conductive material layer 201 of the shielding element 2 and radiated by the shielding element 3, can be grounded through the grounding structural element 1, so as to realize the shielding effect on the shielding element 3. In addition, the conductive region of the shielding element 2 is supported by the supporting structure 5, so that the contact reliability between the conductive material layer 201 and the grounding structural element 1 can be effectively improved, and the stability of the shielding effect of the shielding element 3 to be treated can be improved.

Referring to fig. 3, in some embodiments of the present application, the shielding element 2 may be arranged differently from the above-described embodiments, and specifically, the shielding element 2 includes a first insulating material layer 203 and a conductive material layer 201 which are stacked. The conductive material layer 201 may be made of a metal such as copper capable of conducting an electrical signal, and the first insulating material layer 203 may be a layer structure formed by an insulating adhesive or the like coated or adhered on the conductive material layer 201. In addition, the side of the conductive material layer 201 facing the ground structure member 1 may be divided into a conductive region (a region having a length L2 on the conductive material layer 201 in fig. 3) in conductive contact with the ground structure member 1, and an insulating region other than the conductive region, to which the first insulating material layer 203 is disposed.

With continued reference to fig. 3, in this embodiment, the first insulating material layer 203 of the shielding element 2 can be attached to the grounding structure 1, so that unstable contact between the conductive material layer 201 and the grounding structure 1 due to lack of reliable crimping force can be avoided, and signal interference to the shielding element 3 and the antenna can be avoided. In addition, by attaching the first insulating material layer 203 of the shielding element 2 to the grounding structural member 1, the conductive material layer 201 can be exposed, so that the conductive material layer 201 of the shielding element 2 can receive the electric signal radiated by the element 3 to be shielded conveniently.

The conductive region of the shielding element 2 is disposed on the portion of the shielding element 2 attached to the hole wall of the via hole 101, and the area, position, etc. of the portion of the grounding structure 1 near the side of the to-be-shielded element 3 can be selected according to the shielding requirement of the to-be-shielded element 3. In this embodiment, when the first insulating material layer 203 is an insulating glue, the insulating glue may be adhered to the grounding structural member 1 to fix the shielding element 2 and the grounding structural member 1; when the first insulating material layer 203 does not have adhesiveness, an adhesive such as an adhesive paste may be applied between the first insulating material layer 203 and the ground structure member 1 to fix the first insulating material layer 203 and the ground structure member 1. With continued reference to fig. 3, the conductive region of the shielding element 2 can contact the grounding structure 1 under the supporting force of the supporting structure 5, so as to achieve stable conduction between the shielding element 2 and the grounding structure 1. In addition, this scheme of adoption still is favorable to shortening the design length of shielding part 2 to practice thrift the cost.
