Description

Technical Field

[0001] The present application relates to the field of electronic equipment, and in particular to an anti-static component and a foldable electronic device. Background Art

[0002] Electrostatic discharge has brought great harm to electronic components, especially electrostatic sensitive devices (ESSD). With the development of electronic components in recent years, the tolerance of ESSD devices to static electricity has become lower and lower. Without reasonable protective measures, it is easy to fail due to electrostatic discharge (ESD) during use.

[0003] Folding terminal devices using flexible displays, because the screen of the flexible display will move during the unfolding and bending process, and cannot be completely attached to the mobile phone frame structure or auxiliary materials, so a non-metallic shell is used to protect the edge of the flexible display. However, the conductivity of such non-metallic parts is generally poor, which causes static electricity generated in the screen area to easily enter the device through the gap between the screen and the shell. Therefore, the FPC bending area of ​​the flexible display is prone to ESD failure, which in turn causes the flexible display to fail. Therefore, how to design an anti-static component that can guide static electricity to the ground in time to avoid damage to the flexible display has become a problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0045] The following explains the terms that may appear in the embodiments of the present application.

[0046] Coupling: can be understood as direct coupling and / or indirect coupling, and "coupled connection" can be understood as direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection", which is understood as the physical contact and electrical conduction between components; it can also be understood as the connection between different components in the circuit structure through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals; "indirect coupling" can be understood as two conductors being electrically conductive in an airless / non-contact manner. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by coupling between the gaps between two conductive parts to form an equivalent capacitor.

[0047] Connected / connected: can refer to a mechanical connection relationship or a physical connection relationship. For example, A and B are connected or A and B are connected can mean that there is a fastening component (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0048] Connection: The above-mentioned "electrical connection" or "indirect coupling" method is used to make two or more components conductive or connected to each other for signal / energy transmission, which can be called connection.

[0049] Relative / relative setting: The relative setting of A and B may refer to A and B being face to face (opposite to, or face to face).

[0050] Ground, or floor: can refer to at least a part of any grounding layer, grounding plate, or grounding metal layer in an electronic device (such as a mobile phone), or at least a part of any combination of any of the above grounding layers, grounding plates, or grounding components, etc. "Ground" can be used for grounding components in electronic devices. In one embodiment, "ground" can be a grounding plate formed by the frame of the electronic device or a grounding metal layer formed by a metal film under the screen.

[0051] Any of the above-mentioned grounding layers, grounding plates, or grounding metal layers are made of conductive materials, and the conductive materials may be any of the following materials: copper, aluminum, stainless steel, brass and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil and tin-plated copper on an insulating substrate, cloth impregnated with graphite powder, graphite-coated substrates, copper-plated substrates, brass-plated substrates, and aluminum-plated substrates. It will be appreciated by those skilled in the art that the grounding layer / grounding plate / grounding metal layer may also be made of other conductive materials.

[0052] Considering the RF and antenna requirements of terminal equipment, the small A shell that wraps the edge of the flexible display screen is generally an insulating non-metallic product. The small A shell serves as a link between the mobile phone screen and the body. The overall structure is a small frame, and the bonding strength between it and the body must ensure the fixation of the mobile phone screen. In order to add a high-conductivity ESD protection structure on one side of the FPC bending area of ​​the flexible display screen that is prone to ESD (Electro-Static discharge) failure, conductive silver paste is usually used to adhere to the inner side of the insulating small A shell, and static electricity is guided through the conductive structure and the middle frame to be reasonably grounded to achieve anti-static protection.

[0053] The current grounding method is extremely unstable due to the influence of the assembly process and tolerance, resulting in the spring clip connecting the small A shell to a situation where it seems to be connected but not connected, which is easy to generate harmonics and noise, leading to radiated spurious emission (RSE) problems, affecting the test results of other RF performance of the mobile phone.

[0054] The embodiment of the present application provides an anti-static component to solve the instability problem of contact anti-static of flexible display screens, and can guide static electricity to ground in time to avoid damage to the flexible display screen.

The third fixing portion 117 and the fourth fixing portion 118 increase the welding area of ​​the bottom surface, improve the stability of the connection between the spring piece and the middle frame, thereby improving the stability of the spring piece and the first frame, so that the grounding effect is better.

[0063] Optionally, the first fixing portion 113 , the second fixing portion 114 , the third fixing portion 117 or the fourth fixing portion 118 fixes the spring piece 110 in the second receiving groove 1012 by welding, thereby improving the stability of the connection between the spring piece 110 and the middle frame 101 .

[0065] Alternatively, if Figure 4 and Figure 5 As shown, a limiting groove 1015 is set at the bottom of the second accommodating groove 1012, and the limiting groove 1015 extends along the first direction; the spring piece 110 also includes a retaining rib 119, which is set in the limiting groove 1015, so that the movement path in the second direction becomes shorter when the elastic part 112 moves, thereby increasing the elastic force of the spring piece.

[0066] Optionally, the first fixing portion 113 and the second fixing portion 114 are symmetrically arranged with the axis of the crimping portion 111 as the symmetry axis, wherein the extension direction of the axis of the crimping portion 111 is the second direction.

[0068] The embodiment of the present application shortens the length of the spring sheet 110 in the first direction, i.e., the y-axis, by providing the second receiving groove 1012 and the spring sheet 110 with a V-shaped symmetrical structure, increases the elastic force of the spring sheet 110, and prolongs the service life of the spring sheet 110. The symmetrical arrangement also enables the spring connection between the spring sheet 110 and the first frame 102 to be more stable and accurate. The embodiment of the present application is not limited to the shapes of the second receiving groove 1012 and the spring sheet 110.

[0069] Alternatively, if Figure 4 As shown, the middle frame 101 also includes an insulating portion 1014, which is arranged between the first accommodating groove 1011 and the second accommodating groove 1012, and is used to form an insulating barrier between the first frame 102 and the first fixing portion 113, the second fixing portion 114, the third fixing portion 117 or the fourth fixing portion 118 of the spring 110, which helps to improve the stability of the spring connection between the first frame 102 and the spring 110; optionally, the surface of the insulating portion 1014 is higher than the bottom surface of the first accommodating groove 1011 or the second accommodating groove 1012, so that the insulating portion 1014 forms a protruding structure relative to the first accommodating groove 1011 or the second accommodating groove 1012, and when the first extension portion 1021 of the first frame 102 is installed in the first accommodating groove 1011, the connection area between the first frame 102 and the middle frame 101 is increased, thereby improving the stability of the connection of the first frame 102.

[0070] In the embodiment of the present application, an insulating portion is provided to form a natural barrier between the spring sheet and the first frame, thereby avoiding the need to provide the spring sheet near the first frame close to the antenna, which would affect the use function of the antenna.

[0071] Alternatively, if Figure 6 and Figure 7As shown, the first frame 102 also includes a second extension portion 1022, which extends along the second direction and is higher than the spring sheet 110 in the third direction. The second extension portion 1022 can cover the spring sheet 110 in the second direction, so that the spring sheet 110 is blocked by the second extension portion 1022, thereby improving the stability of the connection.

[0075] Optionally, the first conductive structure 103 can be arranged at a portion of the first frame 102 away from the antenna to avoid affecting the use of the antenna, and this embodiment of the present application does not specifically limit this. Exemplarily, when the first conductive structure 103 is a conductive silver paste, the conductive silver paste can be coated along the first frame 102 close to the first receiving groove 1011 in a circle, and the coating width is set to avoid the antenna area.

[0078] During use, when static electricity passes through the gap between the first shell and the screen, objects with different electrostatic potentials approaching or directly contacting each other will cause charge transfer.
