TECHNICAL FIELD
[0001] The present application belongs to the technical field of electronics, and particularly relates to an electronic device. BACKGROUND
[0002] With the continuous development of electronic devices, electronic devices are now favored by the majority of users due to their portability and rich operability. A large number of components are provided on the circuit board of the electronic device, and some of the components are sensitive components. When these components are working, the electromagnetic waves generated by the outside world will affect the normal work of these components. In the related art, a shielding member is usually provided at the sensitive component to shield the electromagnetic waves from the outside world and prevent the electromagnetic waves generated by the sensitive component from being radiated outward.
[0003] In order to realize the shielding effect of the shielding member, the shielding member needs to be grounded. In the related art, the shielding member and the shell of the electronic device are electrically connected through an electrical connecting member to realize the grounding of the shielding member and thus realize the shielding effect of the shielding member. However, when the circuit board shakes or deforms, the electrical connecting member is easy to press the shielding member and cause damage to the shielding member, thereby causing the shielding member to fail to play a shielding effect.
[0004] Therefore, in the related art, the shielding member is easy to be damaged by the electrical connecting member and thus fails to play an electromagnetic shielding effect. SUMMARY
[0005] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem that the shielding member is easy to be damaged by the electrical connecting member and thus fails to play an electromagnetic shielding effect in the related art.
[0006] The embodiments of the present application provide an electronic device, which comprises:
[0007] A circuit board, wherein the circuit board is provided with a shielding member, the shielding member covers at least part of the components on the circuit board, and the shielding member is electrically connected with a grounding circuit of the circuit board;
[0008] A support and a bearing, wherein the support and the bearing are respectively located on two opposite sides of the circuit board, and the support and the bearing are both connected with the circuit board;
[0009] An electrical connecting member, which is spaced apart from the shielding member;
[0010] The circuit board is provided with a through hole, the electrical connecting member comprises a connecting member body and an elastic member, a first end of the connecting member body passes through the through hole and is connected with a first end of the elastic member, one of a second end of the connecting member body and a second end of the elastic member is connected with the support, and the other is connected with the bearing, so that the electrical connecting member is electrically connected with the support and the bearing at the same time.
[0011] In the embodiment of the present application, the electric connector is arranged apart from the shielding member, the shielding member is electrically connected with the grounding circuit of the circuit board, and the electric connector electrically connects the grounding circuit of the circuit board with the support and the carrier at the same time to realize the grounding of the shielding member through the support and the carrier. In this way, the electric connector and the shielding member are not directly connected with each other, and when the circuit board shakes or deforms, the electric connector will not press the shielding member, so that the shielding member is not easy to be damaged, thereby prolonging the service life of the shielding member and ensuring the electromagnetic shielding effect of the shielding member. Moreover, the electric connector comprises a connector main body and an elastic member, the first end of the connector main body passes through the through hole on the circuit board and is connected with the first end of the elastic member, one of the second end of the connector main body and the second end of the elastic member is connected with the support, and the other is connected with the carrier. In this way, the electric connector can be in good contact with the support and the carrier to improve the grounding effect, and the electric connector can also adapt to the deformation of the circuit board, the support or the carrier, thereby prolonging the service life of the electric connector. Meanwhile, the elastic member can also play a role in restraining the deformation of the circuit board. When the electronic device falls or is impacted, the elastic member can buffer the circuit board, thereby prolonging the service life of the circuit board, and the circuit board, the support and the carrier will not press the shielding member to cause damage to the shielding member.
[0012] In the embodiment of the present application, the shielding member can be a shielding coating. The shielding coating is relatively thin, which can reduce the thickness of the shielding member, thereby effectively reducing the overall thickness of the circuit board, so as to facilitate the reduction of the thickness of the electronic device. Meanwhile, even if the shielding coating is relatively thin, the problem that the shielding coating is damaged by being pressed by the electric connector will not easily occur. Therefore, when the shielding member is a shielding coating, the above-mentioned effects of the embodiment of the present application are more significant. BRIEF DESCRIPTION OF DRAWINGS

[0038] The electronic device provided by the embodiments of the present application will be described in detail below in conjunction with the drawings, specific embodiments and application scenarios.
[0039] Reference Figures 1-16 The electronic device provided by the embodiments of the present application can include a circuit board 100, a support 200, a carrier 300, and an electrical connector 400. The support 200 and the carrier 300 can be located on opposite sides of the circuit board 100, respectively, and the support 200 and the carrier 300 can be connected to the circuit board 100 to be able to fix and support the circuit board 100.
[0040] Here, the support 200 can be connected with a battery cover of the electronic device, the support 200 can be used to support a camera module of the electronic device, and the support 200 can be used to fix and protect the circuit board 100; the carrier 300 can be part of a housing of the electronic device, specifically, the carrier 300 can be part of a middle frame of the electronic device, and the carrier 300 can be connected with a display screen of the electronic device to support the display screen. It should be noted that the circuit board 100 can be a mainboard of the electronic device.
[0041] Optionally, the support 200 can be provided with a first support column 230 on a side close to the circuit board 100, the first support column 230 can be connected with the circuit board 100 by a screw, and the carrier 300 can be provided with a second support column 320 on a side close to the circuit board 100, the second support column 320 can be connected with the circuit board 100 by a screw. In this way, a space for accommodating the shielding member 120 and the components 110 can be formed between the support 200 and the circuit board 100 and between the carrier 300 and the circuit board 100, so as to avoid the shielding member 120 and the components 110 from contacting the support 200 or the carrier 300. In the embodiment, the circuit board 100 can be provided with a mounting hole 140, the mounting hole 140 can penetrate the circuit board 100 along the thickness direction of the circuit board 100, and the first support column 230 and the second support column 320 can be arranged opposite to the mounting hole 140, and the screw can be connected with the second support column 320 through the first support column 230 and the mounting hole 140 in sequence.
[0042] Further, in order to improve the stability of the connection between the support 200 and the carrier 300 and the circuit board 100 and ensure the force balance of the circuit board 100, the support 200 can be provided with four first support columns 230 on a side close to the circuit board 100, the four first support columns 230 can be respectively located at four corners of the support 200, and the carrier 300 can be provided with four second support columns 320 on a side close to the circuit board 100, the four second support columns 320 can correspond to the four first support columns 230 one by one, and here, the support 200 can be a rectangular plate structure.
[0043] The circuit board 100 can be provided with a shielding member 120, the shielding member 120 can cover at least part of the components 110 on the circuit board 100, specifically, the shielding member 120 can cover all sensitive components on the circuit board 100, that is, all components on the circuit board 100 that need electromagnetic shielding, the shielding member 120 can be electrically connected with the ground circuit of the circuit board 100, the electrical connector 400 can be electrically connected with the ground circuit of the circuit board 100, and the electrical connector 400 can be electrically connected with the bracket 200 and the carrier 300 at the same time. In this way, the grounding of the shielding member 120 can be achieved; in addition, the electrical connector 400 and the shielding member 120 can be arranged at intervals, so that there is no direct connection between the electrical connector 400 and the shielding member 120, when the circuit board 100 shakes or deforms, the electrical connector 400 will not press the shielding member 120, so that the shielding member 120 is not easy to be damaged, thereby prolonging the service life of the shielding member 120 and ensuring the electromagnetic shielding effect of the shielding member 120.
[0044] Here, the electrical connector 400 can be electrically connected with the bracket 200 and the carrier 300 at the same time, specifically, the electrical connector 400 can be electrically connected with the metal structure (specifically, the metal member 220 described below) on the bracket 200 and the metal structure on the carrier 300, in this way, the shielding member 120 can be electrically connected with the bracket 200 through the circuit board 100 and the electrical connector 400, since the bracket 200 is connected with the battery cover of the electronic device, the shielding member 120 can be grounded through the battery cover of the electronic device and then through the human body; the shielding member 120 can also be electrically connected with the carrier 300 through the circuit board 100 and the electrical connector 400, since the carrier 300 is connected with the display screen of the electronic device, the shielding member 120 can be grounded through the display screen of the electronic device and then through the human body.
[0045] In optional embodiments of the present application, the shielding member 120 can be a shielding coating, which is relatively thin, can reduce the thickness of the shielding member 120, and thus can effectively reduce the overall thickness of the circuit board 100, thereby facilitating the reduction of the thickness of the electronic device. At the same time, even if the shielding coating is relatively thin, it is not easy to be damaged by being pressed by the electrical connector 400, so the above-mentioned effects of the embodiments of the present application are more significant when the shielding member 120 is a shielding coating.
[0046] Of course, in other embodiments, the shielding member 120 can also be a shielding cover, here, the shielding cover can be a metal cover.
[0047] In optional embodiments of the present application, the electrical connector 400 and the ground circuit of the circuit board 100 can be connected by the elastic connector 500, and the electrical connector 400 and the ground circuit of the circuit board 100 can be electrically connected by the elastic connector 500. In this way, the electrical connection between the electrical connector 400 and the ground circuit of the circuit board 100 can be achieved, and the electrical connector 400 can also be adapted to the deformation of the circuit board 100 through the elastic connector 500. At the same time, the elastic connector 500 can also play a role in restraining the fluctuation and deformation of the circuit board 100, so as to play a buffering role on the circuit board 100 after the electronic device falls or is impacted, thereby being conducive to prolonging the service life of the circuit board 100. Specifically, when the circuit board 100 fluctuates and deforms towards the elastic connector 500, the circuit board 100 will be subjected to the reverse force of the elastic arm 520 due to the limiting cooperation between the elastic connector 500 (specifically, the elastic arm 520 described below) and the electrical connector 400, thereby playing a role in restraining the deformation of the circuit board 100.
[0048] In other embodiments, the electrical connector 400 can also be directly connected to the ground circuit of the circuit board 100.
[0049] In optional embodiments, the elastic connector 500 can include a connecting ring 510 and at least two elastic arms 520. The connecting ring 510 can be sleeved outside the electrical connector 400. Specifically, the connecting ring 510 can be sleeved outside the connector body 410, and the connecting ring 510 can be connected to the circuit board 100. The connecting ring 510 can also be electrically connected to the ground circuit of the circuit board 100. In this way, on the one hand, the connecting area of the elastic connector 500 and the ground circuit of the circuit board 100 can be increased, thereby improving the connection strength of the elastic connector 500 and the circuit board 100. On the other hand, the electrical conductivity of the elastic connector 500 and the ground circuit can be improved. The elastic arms 520 can be distributed at intervals along the circumference of the connecting ring 510. One end of each elastic arm 520 can be connected to and electrically connected to the connecting ring 510. The other end of each elastic arm 520 can be connected to and electrically connected to the electrical connector 400. In this way, while ensuring the elastic deformation function of the elastic connector 500, the electrical conductivity of the elastic connector 500 and the electrical connector 400 can be improved.
[0050] Of course, the elastic connector 500 can also only include the elastic arm 520. Specifically, one end of the elastic arm 520 is directly connected to the ground circuit of the circuit board 100, and the other end of the elastic arm 520 is connected to the electrical connector 400.
[0051] Optionally, a protrusion 411 can be arranged on the sidewall of the electrical connector 400, and the elastic arm 520 can be in position-limiting cooperation with the protrusion 411 in the direction from the connecting ring 510 to the elastic arm 520. In this way, the detachable connection between the electrical connector 400 and the elastic connector 500 can be achieved, and the elastic arm 520 can be limited in position to prevent the elastic arm 520 from separating from the electrical connector 400. Of course, the protrusion 411 can not be arranged on the sidewall of the electrical connector 400, and in this case, the elastic arm 520 and the electrical connector 400 are not in position-limiting cooperation.
[0052] Further optionally, an abutting portion 521 can be arranged at the end of the elastic arm 520 away from the connecting ring 510, the abutting portion 521 can be bent away from the electrical connector 400, and the abutting portion 521 can be attached to the protrusion 411. In this way, the contact area between the elastic arm 520 and the electrical connector 400 can be increased, and the electrical conductivity between the elastic connector 500 and the electrical connector 400 can be improved.
[0053] In some embodiments, a first ground pad can be arranged on the circuit board 100, the first ground pad can be electrically connected to the ground circuit of the circuit board 100, and the connecting ring 510 can be welded to the first ground pad. Here, the first ground pad can be a ring-shaped pad, and the ring-shaped pad can surround the through hole 130 described below.
[0054] In optional embodiments of the present application, the through hole 130 can be arranged on the circuit board 100, one end of the electrical connector 400 can be connected to the support 200, and the other end of the electrical connector 400 can pass through the through hole 130 and be connected to the carrier 300. In this way, the support 200 and the carrier 300 can provide support and fixation for the electrical connector 400, and the electrical connector 400 can move relative to the circuit board 100, and when the circuit board 100 shakes or deforms, the electrical connector 400 is not easily shaken or deformed by the force of the circuit board 100, thereby prolonging the service life of the electrical connector 400.
[0055] In other embodiments, the through hole 130 can not be arranged on the circuit board 100, one end of the electrical connector 400 can be connected to the circuit board 100, and the other end of the electrical connector 400 can be connected to the support 200 or the carrier 300.
[0056] In an optional embodiment, the electric connector 400 can include a connector body 410 and an elastic member 420, the first end of the connector body 410 can pass through the through hole 130 and be connected with the first end of the elastic member 420, one of the second end of the connector body 410 and the second end of the elastic member 420 can be connected with the bracket 200, and the other can be connected with the carrier 300, so that the electric connector 400 is electrically connected with the bracket 200 and the carrier 300 at the same time. In this way, the elastic member 420 can provide a counteracting force to the connector body 410, so that the connector body 410 can maintain good contact with the bracket 200 or the carrier 300, and at the same time, the elastic member 420 can also enable the connector body 410 to adapt to the deformation of the circuit board 100, the bracket 200 or the carrier 300, thereby facilitating the extension of the service life of the connector body 410.
[0057] In the embodiment, the elastic member 420 can further function to constrain the deformation of the circuit board 100. After the electronic device is dropped or impacted, the elastic member 420 can function to buffer the circuit board 100, thereby facilitating the extension of the service life of the circuit board 100. Specifically, when the circuit board 100 fluctuates and deforms towards the elastic member 420, due to the small gap between the through hole 130 and the connector body 410, the circuit board 100 will apply a force towards the elastic member 420 when it fluctuates and deforms, thereby causing the connector body 410 to press the elastic member 420. At this time, the elastic member 420 deforms under force and applies a counteracting force to the connector body 410, and the connector body 410 transmits the counteracting force to the circuit board 100, thereby functioning to constrain the deformation of the circuit board 100, and also avoiding the damage of the shielding member 120 caused by the compression of the circuit board 100, the bracket 200 and the carrier 300 to the shielding member 120 after the deformation of the circuit board 100.
[0058] It should be noted that the through hole 130 and the connector body 410 can be gap-fitted, and here, the hole diameter of the through hole 130 can be equal to the diameter of the connector body 410.
[0059] Optionally, one of the bracket 200 and the carrier 300 can be provided with a guide groove 311, the guide groove 311 can be oppositely arranged with the through hole 130, the elastic member 420 can be located in the guide groove 311, and the first end of the connector body 410 can be slidingly arranged in the guide groove 311, and the second end of the elastic member 420 can be connected with the groove bottom of the guide groove 311. In this way, the guide groove 311 can not only provide mounting space for the elastic member 420, but also guide the movement of the connector body 410 to avoid the deviation of the connector body 410 when moving. Of course, the bracket 200 and the carrier 300 can also not be provided with the guide groove 311.
[0060] Further optionally, one of the bracket 200 and the carrier 300 can be provided with a guide portion 310, the guide portion 310 can protrude towards the circuit board 100, a guide slot 311 can be arranged on the guide portion 310, and the guide portion 310 can be a conductive structure, here, the guide portion 310 can be a metal structure, a part of the connector main body 410 can be in contact with the guide portion 310, so as to increase the contact area between the electrical connector 400 and the bracket 200 or the carrier 300, and further improve the electrical conductivity between the electrical connector 400 and the bracket 200 or the carrier 300.
[0061] In the embodiment, the second end of the connector main body 410 can be connected with the bracket 200, and the guide slot 311 can be arranged on the carrier 300. Of course, the second end of the connector main body 410 can also be connected with the carrier 300, and the guide slot 311 can also be arranged on the bracket 200.
[0062] In the optional embodiment, one of the bracket 200 and the carrier 300 can be provided with an adjusting member 600, the adjusting member 600 can move along the axial direction of the through hole 130 relative to the bracket 200 or the carrier 300, for example, when the bracket 200 is provided with the adjusting member 600, the adjusting member 600 can move along the axial direction of the through hole 130 relative to the bracket 200; when the carrier 300 is provided with the adjusting member 600, the adjusting member 600 can move along the axial direction of the through hole 130 relative to the carrier 300. And one end of the electrical connector 400 can be connected with the adjusting member 600. In this way, the elastic force of the elastic member 420 and the elastic connector 500 described above can be adjusted without disassembling the bracket 200 or the carrier 300, and further the contact force between the electrical connector 400 and the bracket 200 and the carrier 300 can be adjusted, and the contact force between the elastic connector 500 and the electrical connector 400 and the circuit board 100 can be adjusted, so as to facilitate to ensure the electrical conductivity between the electrical connector 400 and the circuit board 100, the bracket 200 and the carrier 300, and to improve the grounding effect.
[0063] Of course, in other embodiments, the bracket 200 and the carrier 300 can also not be provided with the adjusting member 600.
[0064] Optionally, the adjusting member 600 can be an adjusting screw, the support 200 or the carrier 300 can be embedded with a nut 210, and the adjusting screw and the nut 210 can be threadedly connected, and the threaded hole of the nut 210 can be coaxially arranged with the through hole 130, so that the elastic force of the elastic member 420 can be adjusted only by screwing the adjusting screw, which is simple in structure and convenient to operate; and the nut 210 is embedded in the support 200 or the carrier 300, which on the one hand facilitates contact with the metal member 220 in the support 200 or the carrier 300, and on the other hand can reduce the thickness of the support 200 or the carrier 300, and can improve the structural strength of the support 200 or the carrier 300. For example, when the nut 210 is embedded in the support 200, the metal member 220 on the support 200 can be facilitated to contact and the structural strength of the support 200 can be improved; when the nut 210 is embedded in the carrier 300, the metal member on the carrier 300 can be facilitated to contact and the structural strength of the carrier 300 can be improved.
[0065] Here, the nut 210 can be electrically connected with the support 200 or the carrier 300, and the adjusting screw and the nut 210 can both be conductive structures, so that the electrical connection 400 and the support 200 can be electrically connected through the adjusting screw and the nut 210.
[0066] In the present embodiment, the nut 210 can be arranged on the support 200, and the adjusting member 600 is movably arranged on the support 200, so that when the elastic force of the elastic member 420 and the elastic connection 500 needs to be adjusted, the adjusting member 600 can be exposed by opening the battery cover, thereby facilitating the operation of the adjusting member 600. Here, the support 200 can be provided with a metal member 220, and the nut 210 can be in contact with the metal member 220, the metal member 220 can be a metal plate, and the metal member 220 can be arranged inside the support 200 or on the surface of the support 200, and the metal member 220 can cover at least part of the support 200 to improve the structural strength of the support 200.
[0067] In the present embodiment, the adjusting screw and the nut 210 are used in cooperation, which is simpler in structure, easier to arrange, lower in cost, and easier to achieve electrical connection with the support 200, compared with the use of a telescopic member to adjust the elastic member 420.
