Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In order to facilitate understanding of the technical solutions of the present application, first, technical problems to be solved by the present application will be described.

Screen definition is one of the core indicators of electronic devices. In some implementations, the antennas of the electronic device are distributed around the body of the handset, which becomes a typical resonant cavity structure when there is a physical gap between the screen and the metal bezel (body bezel). When the ability of a plurality of frequency channels coupling antenna radiation, clutter is produced in the effective band of antenna, and then clutter such as lines appears in the screen to influence the screen definition.

In one solution, as shown in fig. 1, the electronic device includes a screen 100 and an electric welding reed 60 provided on a main body middle frame 200. To ground the screen, the metal foil 40 under the screen 100 is electrically connected to the electric welding reed 60. A conductive medium having elasticity is provided between metal foil 740 and electric welding reed 60. For example a foam 10 coated with a conductive cloth 20. External force is applied to the screen 100 and the main body middle frame 200 through the elasticity of the foam 10, so that the conductive cloth 20 is attached to the metal foil 40, and the conductive cloth 20 is attached to the electric welding elastic sheet 60, the grounding of the screen is realized, and the resonant cavity structure is eliminated.

In another solution, as shown in fig. 2, a Z-shaped elastic sheet 30 is disposed between the metal foil 40 under the screen 100 and the main body middle frame 200, the elastic sheet 30 is respectively connected with the metal foil 40 under the screen 100 and the main body middle frame 200, and the metal foil 40 is tightly and fixedly connected with the welding spring 60 by the elastic force of the elastic sheet 30 itself, so as to realize the grounding of the screen and eliminate the noise of the screen. According to the two schemes, the screen is grounded by arranging the elastic material between the screen and the main body middle frame, but because the foam and the metal elastic sheet are both made of the elastic material, if the elastic force is too large, a die mark can be generated on the surface of the screen, and the user experience is influenced. If the elasticity is too small, the resonant cavity cannot be effectively eliminated or the screen is grounded, clutter still can be generated on the surface of the screen, and the use experience of a user is reduced.

In order to solve the above problem, the present application provides an electronic device, in which a metal foil below a screen is extended to form a grounding strip, and the grounding strip is fixedly connected to a metal member on a middle frame of a main body in a manner of applying a force to the middle frame of the main body, so as to ground the screen. Thereby avoiding the force from being applied to the screen and avoiding the risk of stamping.

Thereby achieving the effect of transferring the force applied to the screen 100 to the body middle frame 200, without the need to apply the force to the screen. This structure has not only realized the screen ground protection, and need not increase other conductive medium and exert force to the screen between first metalwork 100 and second metalwork 400, not only can ensure the effective connection of screen 100 with main part center 200, avoids increasing conductive medium simultaneously, makes the screen receive the risk that takes place the moulding when too big pressure, perhaps the undersize leads to taking place the stray risk of radiation.
