Description
Technical Field
[0001] The present application belongs to the field of electronic technology, and specifically relates to an electronic device. Background Art
[0002] With the continuous development of electronic devices, electronic devices are now loved by the majority of users due to their portability and rich and diverse operability. There are a large number of components on the circuit board of the electronic device, and some components are sensitive devices. When these components are working, the electromagnetic waves generated by the outside world will affect the normal operation of these components. In the related art, a shielding member is usually set at the sensitive device to shield the interference of the external electromagnetic waves on the sensitive device, and prevent the electromagnetic waves generated by the sensitive device from radiating outward.
[0003] In order to achieve the shielding effect of the shielding component, the shielding component needs to be grounded. In the related art, the shielding component and the housing of the electronic device are electrically connected through an electrical connector to achieve the grounding of the shielding component, thereby achieving the shielding effect of the shielding component. However, when the circuit board shakes or deforms, the electrical connector is easy to squeeze the shielding component and cause damage to the shielding component, thereby causing the shielding component to fail to achieve the shielding effect.
[0004] Therefore, there is a defect in the related art that the shielding component is easily damaged by the electrical connector and cannot play the role of electromagnetic shielding. Summary of the invention
[0005] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem in the related art that the shielding component is easily damaged by the electrical connector and cannot play the role of electromagnetic shielding.
[0006] An embodiment of the present application provides an electronic device, including: A circuit board, wherein a shielding member is disposed on the circuit board, the shielding member covers at least part of the components on the circuit board, and the shielding member is electrically connected to a ground circuit of the circuit board; A bracket and a bearing member, wherein the bracket and the bearing member are respectively located on two opposite sides of the circuit board, and both the bracket and the bearing member are connected to the circuit board; an electrical connector, spaced apart from the shielding member; Wherein, a through hole is provided on the circuit board, and the electrical connector includes a connector body and an elastic member, the first end of the connector body passes through the through hole and is connected to the first end of the elastic member, one of the second end of the connector body and the second end of the elastic member is connected to the bracket, and the other is connected to the supporting member, so that the electrical connector is electrically connected to the bracket and the supporting member at the same time.
[0007] In the embodiment of the present application, the electrical connector is spaced apart from the shielding member, and the shielding member is electrically connected to the grounding circuit of the circuit board. The electrical connector electrically connects the grounding circuit of the circuit board to the bracket and the carrier at the same time, so as to realize the grounding of the shielding member through the bracket and the carrier. In this way, there is no direct connection between the electrical connector and the shielding member. When the circuit board shakes or deforms, the electrical connector will not squeeze the shielding member, thereby making the shielding member less likely to be damaged, which is beneficial to prolonging the service life of the shielding member and ensuring the electromagnetic shielding effect of the shielding member. In addition, the electrical connector includes a connector body and an elastic member, the first end of the connector body passes through the through hole on the circuit board and is connected to the first end of the elastic member, and one of the second end of the connector body and the second end of the elastic member is connected to the bracket, and the other is connected to the carrier. In this way, the electrical connector can maintain good contact with the bracket and the carrier to improve the grounding effect, and the electrical connector can adapt to the deformation of the circuit board, bracket or carrier, which is beneficial to extending the service life of the electrical connector. At the same time, the elastic member can also restrain the deformation of the circuit board. When the electronic device falls or is collided, the elastic member can buffer the circuit board, which is beneficial to extending the service life of the circuit board. It can also prevent the circuit board, bracket and carrier from squeezing the shielding member after the circuit board is deformed, thereby preventing the shielding member from being damaged.
[0008] In the embodiment of the present application, the shielding member may be a shielding coating, which is relatively thin and can reduce the thickness of the shielding member, thereby effectively reducing the overall thickness of the circuit board, thereby facilitating the reduction of the thickness of the electronic device. At the same time, even if the shielding coating is relatively thin, the shielding coating is not easily damaged by being squeezed by the electrical connector, so when the shielding member is a shielding coating, the above-mentioned effect of the embodiment of the present application is more significant.

DETAILED DESCRIPTION
[0011] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.
[0012] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0013] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.
[0014] refer to Figure 1-Figure 16 , an electronic device provided by an embodiment of the present application may include a circuit board 100, a bracket 200, a carrier 300 and an electrical connector 400. The bracket 200 and the carrier 300 may be located on opposite sides of the circuit board 100, and the bracket 200 and the carrier 300 may be connected to the circuit board 100 to fix and support the circuit board 100.
[0015] Here, the bracket 200 can be connected to the battery cover of the electronic device, the bracket 200 can be used to support the camera module of the electronic device, and the bracket 200 can be used to fix and protect the circuit board 100; the carrier 300 can be a part of the housing of the electronic device, specifically, the carrier 300 can be a part of the middle frame of the electronic device, and the carrier 300 can be connected to the display screen of the electronic device to support the display screen. It should be noted that the circuit board 100 can be the mainboard of the electronic device.
[0016] Optionally, a first pillar 230 may be provided on the side of the bracket 200 close to the circuit board 100, and the first pillar 230 may be connected to the circuit board 100 by screws. A second pillar 320 may be provided on the side of the carrier 300 close to the circuit board 100, and the second pillar 320 may be connected to the circuit board 100 by screws. In this way, a space for accommodating the shielding member 120 and the component 110 may be formed between the bracket 200 and the circuit board 100 and between the carrier 300 and the circuit board 100, so as to prevent the shielding member 120 and the component 110 from contacting the bracket 200 or the carrier 300. In this embodiment, a mounting hole 140 may be provided on the circuit board 100, and the mounting hole 140 may penetrate the circuit board 100 along the thickness direction of the circuit board 100, and the first pillar 230 and the second pillar 320 may be arranged opposite to the mounting hole 140, and the screw may pass through the first pillar 230 and the mounting hole 140 in sequence to connect with the second pillar 320.
[0017] Furthermore, in order to improve the stability of the connection between the bracket 200 and the carrier 300 and the circuit board 100 and to ensure the force balance of the circuit board 100, four first pillars 230 can be provided on the side of the bracket 200 close to the circuit board 100, and the four first pillars 230 can be respectively located at the four corners of the bracket 200, and four second pillars 320 can be provided on the side of the carrier 300 close to the circuit board 100, and the four second pillars 320 can respectively correspond to the four first pillars 230 one by one. Here, the bracket 200 can be a rectangular plate-like structure.
[0018] The circuit board 100 may be provided with a shielding member 120, which may cover at least part of the components 110 on the circuit board 100. Specifically, the shielding member 120 may cover all sensitive devices on the circuit board 100, that is, all devices on the circuit board 100 that require electromagnetic shielding. The shielding member 120 may be electrically connected to the grounding circuit of the circuit board 100, and the electrical connector 400 may be electrically connected to the grounding circuit of the circuit board 100, and the electrical connector 400 may be electrically connected to the bracket 200 and the bearing member 300 at the same time. In this way, the grounding of the shielding member 120 may be achieved; in addition, the electrical connector 400 and the shielding member 120 may 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 squeeze the shielding member 120, thereby making the shielding member 120 less likely to be damaged, thereby helping to extend the service life of the shielding member 120 and ensure the electromagnetic shielding effect of the shielding member 120.
[0019] Here, the electrical connector 400 can be electrically connected to the bracket 200 and the carrier 300 at the same time. Specifically, the electrical connector 400 can be electrically connected to the metal structure on the bracket 200 (specifically, it can be the metal member 220 described later) and the metal structure on the carrier 300. In this way, the shielding component 120 can be electrically connected to the bracket 200 through the circuit board 100 and the electrical connector 400. Since the bracket 200 is connected to the battery cover of the electronic device, the shielding component 120 can be grounded through the battery cover of the electronic device and then through the human body; the shielding component 120 can also be electrically connected to the carrier 300 through the circuit board 100 and the electrical connector 400. Since the carrier 300 is connected to the display screen of the electronic device, the shielding component 120 can be grounded through the display screen of the electronic device and then through the human body.
[0020] In an optional embodiment of the present application, the shielding member 120 may be a shielding coating, which is relatively thin and can reduce the thickness of the shielding member 120, thereby effectively reducing 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, the shielding coating is not easily damaged by being squeezed by the electrical connector 400, so when the shielding member 120 is a shielding coating, the above-mentioned effect of the embodiment of the present application is more significant.
[0021] Of course, in other embodiments, the shielding member 120 may also be a shielding cover, and here, the shielding cover may be a metal cover.
[0022] In an optional embodiment of the present application, the electrical connector 400 can be connected to the ground circuit of the circuit board 100 through the elastic connector 500, and the electrical connector 400 and the ground circuit of the circuit board 100 can be electrically connected through 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 adapt 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 certain role in restricting the fluctuation deformation of the circuit board 100, so as to play a buffering role for the circuit board 100 after the electronic device falls or is hit, thereby helping to extend the service life of the circuit board 100. Specifically, when the circuit board 100 fluctuates and deforms toward the elastic connector 500, since the elastic connector 500 (specifically the elastic arm 520 described later) and the electrical connector 400 are limited and matched, the circuit board 100 will be subjected to the reverse force of the elastic arm 520 at this time, thereby playing a role in restricting the deformation of the circuit board 100.
[0023] In other embodiments, the electrical connector 400 may also be directly connected to the ground circuit of the circuit board 100 .
[0024] In an optional embodiment, the elastic connector 500 may include a connecting ring 510 and at least two elastic arms 520. The connecting ring 510 may be sleeved outside the electrical connector 400. Specifically, the connecting ring 510 may be sleeved outside the connector body 410, and the connecting ring 510 may be connected to the circuit board 100. The connecting ring 510 may also be electrically connected to the grounding circuit of the circuit board 100. In this way, on the one hand, the connection area between the elastic connector 500 and the grounding circuit of the circuit board 100 may be increased, thereby improving the elastic connector. On the one hand, the connection strength between 500 and the circuit board 100 can be improved, and on the other hand, the electrical conductivity between the elastic connector 500 and the grounding circuit can be improved; each elastic arm 520 can be distributed at intervals along the circumference of the connecting ring 510, and one end of the elastic arm 520 can be connected to the connecting ring 510 and electrically conductive, and the other end of each elastic arm 520 can be connected to the electrical connector 400 and electrically conductive. In this way, the electrical conductivity between the elastic connector 500 and the electrical connector 400 can be improved while ensuring that the elastic connector 500 has the function of elastic deformation.
[0025] Of course, the elastic connector 500 may 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 .
[0026] Optionally, a convex portion 411 may be provided on the side wall of the electrical connector 400, and the elastic arm 520 and the convex portion 411 may be limitedly matched 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 to prevent the elastic arm 520 from being separated from the electrical connector 400. Of course, the convex portion 411 may not be provided on the side wall of the electrical connector 400, and in this case, there is no limitedly matched relationship between the elastic arm 520 and the electrical connector 400.
[0027] Further optionally, an abutment portion 521 may be provided at one end of the elastic arm 520 away from the connecting ring 510, and the abutment portion 521 may be bent away from the electrical connector 400, and the abutment portion 521 may be fitted with the protrusion 411, so that the contact area between the elastic arm 520 and the electrical connector 400 may be increased, thereby improving the electrical conductivity between the elastic connector 500 and the electrical connector 400.
[0028] In some embodiments, a first grounding pad is provided on the circuit board 100, the first grounding pad is electrically connected to the grounding circuit of the circuit board 100, and the connecting ring 510 can be welded to the first grounding pad. Here, the first grounding pad can be an annular pad, and the annular pad can be arranged around the through hole 130 described below.
[0029] In an optional embodiment of the present application, a through hole 130 may be provided on the circuit board 100, one end of the electrical connector 400 may be connected to the bracket 200, and the other end of the electrical connector 400 may pass through the through hole 130 and be connected to the carrier 300. In this way, the bracket 200 and the carrier 300 may provide support and fixation for the electrical connector 400, and the electrical connector 400 may move relative to the circuit board 100. 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, which is conducive to extending the service life of the electrical connector 400.
[0030] In other embodiments, the through hole 130 may not be provided on the circuit board 100 , one end of the electrical connector 400 may be connected to the circuit board 100 , and the other end of the electrical connector 400 may be connected to the bracket 200 or the carrier 300 .
[0031] In an optional embodiment, the electrical connector 400 may include a connector body 410 and an elastic member 420, the first end of the connector body 410 may pass through the through hole 130 and be connected to 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 may be connected to the bracket 200, and the other may be connected to the carrier 300, so that the electrical connector 400 is electrically connected to the bracket 200 and the carrier 300 at the same time. In this way, the elastic member 420 can provide a reverse force to the connector body 410, so that the connector body 410 maintains 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.
[0032] In this embodiment, the elastic member 420 can further play a role in restraining the deformation of the circuit board 100. When the electronic device falls or is hit, the elastic member 420 can buffer the circuit board 100, thereby helping to extend the service life of the circuit board 100. Specifically, when the circuit board 100 fluctuates and deforms toward 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 toward the elastic member 420 to the connector body 410 during the fluctuating deformation, thereby causing the connector body 410 to squeeze the elastic member 420. At this time, the elastic member 420 is deformed by force and applies a reverse force to the connector body 410. The connector body 410 transmits the reverse force to the circuit board 100, thereby restraining the deformation of the circuit board 100, and also preventing the circuit board 100, the bracket 200 and the carrier 300 from squeezing the shielding member 120 after the circuit board 100 is deformed, thereby causing the shielding member 120 to be damaged.
[0033] It should be noted that the through hole 130 and the connector body 410 may be clearance-fitted, and here, the aperture of the through hole 130 may be equal to the diameter of the connector body 410 .
[0034] Optionally, a guide groove 311 may be provided on one of the bracket 200 and the bearing member 300, the guide groove 311 may be arranged opposite to the through hole 130, the elastic member 420 may be located in the guide groove 311, and the first end of the connector body 410 may be slidably arranged in the guide groove 311, and the second end of the elastic member 420 may be connected to the bottom of the guide groove 311. In this way, the guide groove 311 can provide an installation space for the elastic member 420 and guide the movement of the connector body 410 to prevent the connector body 410 from deviating when moving. Of course, the guide groove 311 may not be provided on either the bracket 200 or the bearing member 300.
[0035] Further optionally, a guide portion 310 may be provided on one of the bracket 200 and the carrier 300, the guide portion 310 may protrude toward the circuit board 100, the guide groove 311 may be provided on the guide portion 310, and the guide portion 310 may be a conductive structure. Here, the guide portion 310 may be a metal structure, and a portion of the connector body 410 may contact the guide portion 310 to increase the contact area between the electrical connector 400 and the bracket 200 or the carrier 300, thereby improving the electrical conductivity between the electrical connector 400 and the bracket 200 or the carrier 300.
[0036] In this embodiment, the second end of the connector body 410 can be connected to the bracket 200, and the guide groove 311 can be provided on the carrier 300. Of course, the second end of the connector body 410 can also be connected to the carrier 300, and the guide groove 311 can also be provided on the bracket 200.
[0037] In an optional embodiment, one of the bracket 200 and the carrier 300 may be provided with an adjusting member 600, and the adjusting member 600 may move relative to the bracket 200 or the carrier 300 along the axial direction of the through hole 130. For example, when the bracket 200 is provided with the adjusting member 600, the adjusting member 600 may move relative to the bracket 200 along the axial direction of the through hole 130; when the carrier 300 is provided with the adjusting member 600, the adjusting member 600 may move relative to the carrier 300 along the axial direction of the through hole 130. And one end of the electrical connector 400 may be connected to 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, thereby adjusting the contact force between the electrical connector 400 and the bracket 200 and the carrier 300, and adjusting the contact force between the elastic connector 500 and the electrical connector 400 and the circuit board 100, thereby facilitating ensuring the electrical conductivity between the electrical connector 400 and the circuit board 100, the bracket 200 and the carrier 300, and improving the grounding effect.
[0038] Of course, in other embodiments, the adjusting member 600 may not be provided on the bracket 200 and the supporting member 300 .
[0039] Optionally, the adjusting member 600 may be an adjusting screw, the bracket 200 or the bearing member 300 may be embedded with a nut 210, and the adjusting screw and the nut 210 may be threadedly connected, and the threaded hole of the nut 210 may be coaxially arranged with the through hole 130, so that the elastic force of the elastic member 420 can be adjusted by only turning the adjusting screw, which has a simple structure and is easy to operate; and the nut 210 is embedded in the bracket 200 or the bearing member 300, which is convenient for contacting with the metal member 220 in the bracket 200 or the bearing member 300 on the one hand, and can reduce the thickness of the bracket 200 or the bearing member 300 on the other hand, and can improve the structural strength of the bracket 200 or the bearing member 300. For example, when the nut 210 is embedded in the bracket 200, it is convenient for contacting with the metal member 220 on the bracket 200 and improving the structural strength of the bracket 200; when the nut 210 is embedded in the bearing member 300, it is convenient for contacting with the metal member on the bearing member 300 and improving the structural strength of the bearing member 300.
[0040] Here, the nut 210 can be electrically connected to the bracket 200 or the carrier 300 , and both the adjusting screw and the nut 210 can be conductive structures, so that the electrical connection 400 can be electrically connected to the bracket 200 through the adjusting screw and the nut 210 .
[0041] In this embodiment, the nut 210 can be disposed on the bracket 200, so that the adjusting member 600 can be movably disposed on the bracket 200. When the elastic force of the elastic member 420 and the elastic connecting member 500 needs to be adjusted, the adjusting member 600 can be exposed by simply opening the battery cover, thereby facilitating the operation of the adjusting member 600. Here, a metal member 220 can be disposed on the bracket 200, the nut 210 can contact the metal member 220, the metal member 220 can be a metal plate, the metal member 220 can be disposed inside the bracket 200 or on the surface of the bracket 200, and the metal member 220 can cover at least part of the bracket 200 to improve the structural strength of the bracket 200.
[0042] In the embodiment of the present application, the method of matching the adjusting screw and the nut 210 is adopted. Compared with the method of using a telescopic member to adjust the elastic member 420, the structure is simple, easy to arrange, and the cost is low, and it is easy to achieve electrical connection with the bracket 200.
[0043] In other embodiments, the adjusting member 600 may be a telescopic member, which is telescopically arranged on the bracket 200 or the bearing member 300. When the elastic force of the elastic member 420 needs to be adjusted, the telescopic member may be controlled to be telescopic. For example, when the elastic force of the elastic member 420 needs to be increased, the telescopic member may be controlled to be extended. Here, the telescopic member may be a micro electric push rod.
[0044] Further optionally, in order to improve the electrical conductivity between the electrical connector 400 and the adjusting member 600, at least one of the ends of the adjusting member 600 and the electrical connector 400 in contact with each other may be provided with a conductive coating, and the conductivity of the conductive coating may be greater than the conductivity of the adjusting member 600 and the electrical connector 400. Of course, the ends of the adjusting member 600 and the electrical connector 400 in contact with each other may not be provided with a conductive coating.
[0045] Here, the conductive coating can be a copper film, which can be arranged by electroplating on the end where the adjusting member 600 contacts the electrical connector 400 and / or the end where the electrical connector 400 contacts the adjusting member 600; the conductive coating can also be a conductive tape or other special coating material, such as conductive paste.
[0046] In an optional embodiment of the present application, the electronic device may include at least two electrical connectors 400, which may include a first electrical connector 401 and a second electrical connector 402, and the first electrical connector 401 and the second electrical connector 402 may be respectively arranged close to both sides of the circuit board 100 in the first direction, where the first direction may be perpendicular to the thickness direction of the circuit board 100. In this way, on the one hand, the grounding stability of the circuit board 100 may be improved, and on the other hand, it is conducive to ensuring the force balance of the circuit board 100, the bracket 200 and the bearing member 300, thereby extending the service life of the circuit board 100, the bracket 200 and the bearing member 300.
[0047] In other embodiments, the electronic device may include only one electrical connector 400 , or the electronic device may include at least two electrical connectors 400 , and each electrical connector 400 may be disposed close to one side of the circuit board 100 in the first direction.
[0048] In an optional embodiment, the shielding member 120 may include a first shielding member 121 and a second shielding member 122, the first shielding member 121 may be located between the circuit board 100 and the bracket 200, the first shielding member 121 may cover at least part of the components 110 on a side of the circuit board 100 close to the bracket 200, and the first shielding member 121 may be electrically connected to the grounding circuit of the circuit board 100, the second shielding member 122 may be located between the circuit board 100 and the carrier 300, the second shielding member 122 may cover at least part of the components 110 on a side of the circuit board 100 close to the carrier 300, and the second shielding member 122 may be electrically connected to the grounding circuit of the circuit board 100. In this way, the shielding effect of the shielding member 120 may be improved.
[0049] Of course, the shielding member 120 may also only include the first shielding member 121 or the second shielding member 122 .
[0050] Optionally, both the first shielding member 121 and the second shielding member 122 may be shielding coatings. In this way, the thickness of the first shielding member 121 and the second shielding member 122 may be reduced, thereby effectively reducing the overall thickness of the circuit board 100.
[0051] Further optionally, the shielding coating may include a metal layer and an insulating layer, the metal layer may be located on the side of the insulating layer away from the component 110, and the metal layer may be electrically connected to the ground circuit of the circuit board 100. In this way, it can not only play a shielding role, but also avoid the metal layer and the component 110 from forming an electrical connection to cause a short circuit of the component 110.
[0052] In order to facilitate the electrical connection between the metal layer and the grounding circuit of the circuit board 100, a second grounding pad may be provided on the circuit board 100, such as Figure 2 As shown, a grounding protrusion 123 may be provided on the metal layer, and the grounding protrusion 123 may be welded to the second grounding pad. In addition, in order to improve the electrical conductivity between the metal layer and the grounding circuit of the circuit board 100, the grounding protrusion 123 and the second grounding pad may both be annular structures, and the grounding protrusion 123 may be provided around the metal layer, and the grounding protrusion 123 and the second grounding pad are provided correspondingly.
[0053] The electronic device in the embodiment of the present application may be a terminal, or may be other devices except a terminal.
