[0002] When an electronic device (such as a mobile phone) falls, the screen is easily affected by the impact of the fall, resulting in a white spot on the screen. The main reason is that when the electronic device falls, the flexible printed circuit (FPC) inside it hits the screen under the impact force, causing damage to the screen and affecting the normal use of the electronic device.

[0003] Therefore, it is worth considering how to reduce screen damage caused by falling electronic devices. Summary of the invention

That is to say, in the present application, the electrical connection between the small board, the display screen and the main board can be realized through one FPC.

[0019] In combination with the first aspect, in some implementations of the first aspect, one end of the second connection portion is electrically connected to the main body, and the other end of the second connection portion is bent toward the display screen and electrically connected to the display screen.

In the following embodiments, the electronic device is taken as an example for description.

[0042] Figure 1 It is a structural diagram of an electronic device 100 provided in an embodiment of the present application. Figure 2 yes Figure 1 An example exploded view of the electronic device 100 is shown. Figure 3 yes Figure 1 or Figure 2 A partial cross-sectional structural diagram of an electronic device 100 is shown.

[0043] Combination Figures 1 to 3 It can be seen that the electronic device 100 may include a display screen 110, a middle frame 120 and a back cover 130, and the display screen 110 and the back cover 130 are respectively located on both sides of the middle frame 120. A first accommodating cavity may be formed between the middle frame 120 (also referred to as a face shell) and the display screen 110, and a second accommodating cavity may be formed between the middle frame 120 and the back cover 130. It should be understood that some electronic components inside the electronic device 100, such as a processor, a heat dissipation module, a battery, a main board, a small board, an antenna, a camera, a microphone and other devices, may be placed inside the first accommodating cavity and the second accommodating cavity.

[0044] The display screen 110 is a display surface of the electronic device 100, and can be used to display information such as images and texts. The display screen 110 can be a light emitting diode (LED) display screen, a liquid crystal display (LCD) display screen, or an organic light-emitting diode (OLED) display screen, but is not limited thereto. In addition, the display screen 110 can also be a folding screen, a flexible screen, etc.

[0045] For example, Figure 2 and Figure 3 As shown, the electronic device 100 may also include components such as a main board (not shown in the figure), a small board 140, a flexible printed circuit (FPC) 150, and a battery 160. The small board 140 and the battery 160 may be located in the second accommodating cavity, a portion of the FPC 150 may be located in the first accommodating cavity, and another portion of the FPC 150 may be located in the second accommodating cavity. In other words, the middle frame 120 is located between the display screen 110 and the back cover 130, the small board 140 and the battery 160 are located on a side of the middle frame 120 close to the back cover 130, a portion of the flexible printed circuit 150 is located on a side of the middle frame 120 close to the back cover 130, and another portion of the flexible printed circuit 150 is located on a side of the middle frame 120 close to the back cover 130, and another portion of the flexible printed circuit 150 is located on a side of the middle frame 120 close to the back cover 130, and another portion of the flexible printed circuit 150 is located on a side of the middle frame 120 close to the display screen 110.

[0046] The main circuits, chips, sensors, interfaces and plug-ins of the electronic device 100 may be arranged on the main board, and the USB interface, antenna contacts and radio frequency interface of the electronic device 100 may be arranged on the small board 140 .

[0047] Flexible circuit board FPC can be referred to as soft board, also known as "flexible circuit board" or "flexible circuit board, flexible circuit board, flexible circuit board, flexible circuit board", etc. Flexible circuit board is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as a substrate. In the present application, FPC 150 can be bent to form different structures to connect different devices (such as main board, small board, display screen, etc.) to achieve electrical connection with different devices.

[0048] It should be understood that the main board and the small board 140 can be arranged at opposite ends of the battery 160 or the electronic device 100. For example, the main board can be arranged at the upper end (or top) of the battery 160 or the electronic device 100, and the small board 140 can be arranged at the lower end (or bottom) of the battery 160 or the electronic device 100. The bottom of the electronic device 100 can be the end away from the camera.

[0049] The main board, the small board 140 and the display screen 110 may be electrically connected via the FPC 150 . Figures 4 to 6 The structure of FPC150 is shown as Figure 4As shown, the FPC 150 may include a first connection portion 151, a second connection portion 152, a third connection portion 153 and a main body 154, wherein the first connection portion 151, the second connection portion 152 and the third connection portion 153 may be connected (electrically connected) through the main body 154, the first connection portion 151 may be used to electrically connect with the small board 140, the second connection portion 152 may be used to electrically connect with the display screen 110, and the third connection portion 153 may be used to electrically connect with the main board. That is, in the present application, the electrical connection with the main board, the small board 140 and the display screen 110 may be achieved respectively through one FPC 150, thereby simplifying the structure of the FPC 150, simplifying the internal wiring of the FPC 150, and saving the internal space occupied by the FPC 150.

[0050] Exemplary, combined Figures 2 to 6 It can be known that the first connection portion 151 can be used to electrically connect with the small board 140. For example, the electronic device 100 may further include a small board connector 141, and the first connection portion 151 may be electrically connected with the small board 140 through the small board connector 141. For example, the small board connector 141 may be located on a side of the small board 140 away from the display screen 110, and a portion of the first connection portion 151 may be connected to a side of the small board connector 141 away from the small board 140.

[0051] The small board connector 141 may be, for example, a zero insertion force (ZIF) connector or a board to board (BTB) connector.

[0052] like Figure 3 As shown, a battery compartment is provided on one side of the middle frame 120 close to the back cover 130, and the battery compartment is used to accommodate the battery 160, and a through hole 121 is provided on the battery compartment. In other words, a through hole 121 may be provided on the middle frame 120, and at least a part of the structure of the first connecting portion 151 of the FPC 150 may pass through the through hole 121, so that a part of the FPC 150 may be sandwiched between the battery 160 and the middle frame 120. In this way, when the electronic device 100 falls, most of the impact force of the fall can be transmitted to the middle frame 120, rather than directly to the display screen 110, thereby reducing problems such as white spots / white masses on the screen caused by the impact force during the fall, and avoiding screen damage.

[0053] Exemplarily, the through hole 121 can be disposed on one side of the battery compartment close to the small board 140. It should be understood that, considering the internal layout of the electronic device 100, the through hole 121 opened on the middle frame 120 can be disposed on one side close to the small board 140, thereby saving the internal space of the electronic device 100.

[0054] In some examples, such as Figure 5 and Figure 6 As shown, the first connecting portion 151 may include a first connecting segment 1511, a first bending segment 1512, a second connecting segment 1513, a second bending segment 1514 and a third connecting segment 1515 which are connected in sequence.

[0055] Combination Figure 3 It can be seen that the first connecting section 1511 is connected to the side of the small board 140 away from the display screen 110, the first bending section 1512 is bent toward the display screen 110, the second connecting section 1513 is located on the side of the middle frame 120 close to the battery 160, the first bending section 1512 and the second connecting section 1513 are both located between the middle frame 120 and the battery 160, the second bending section 1514 is located in the through hole 121, and the third connecting section 1515 is located on the side of the middle frame 120 away from the battery 160. One end of the third connecting section 1515 can be connected to the second bending section 1514, and the other end of the third connecting section 1515 can be connected to the main body 154.

[0056] It should be understood that by opening the through hole 121 in the battery compartment area of ​​the middle frame 120, the first connecting section 1511, the first bending section 1512, and the second connecting section 1513 of the first connecting portion 151 can pass through the through hole 121, and the second connecting section 1513 can be sandwiched between the middle frame 120 and the battery 160 (located on the side of the middle frame 120 away from the display screen 110), part of the second bending section 1514 can be located in the through hole 121, and the third connecting section 1515 can be located between the middle frame 120 and the display screen 110. Therefore, when the electronic device 100 falls, most of the falling impact force can be transmitted to the middle frame 120 through the second connecting section 1513 for release, thereby reducing problems such as white spots / white masses on the screen caused by the impact force during the fall.

[0057] That is to say, by changing the perforation position of the FPC 150 to the bottom of the battery 160, the impact force of the fall can be transferred from the middle fault (most of the force is first transmitted to the middle frame 120, and a small part of the force is naturally released), thereby avoiding the problem of white spots / white spots on the screen caused by the fall impact force generated when the electronic device 100 falls being transmitted to the display screen 110 through the FPC 150.

[0058] In some examples, the second connection section 1513 can be fixedly connected to the middle frame 120 by a fixing member such as adhesive. That is, adhesive can be provided at the connection between the second connection section 1513 and the middle frame 120, and the adhesive can be used to pre-fix the FPC 150 and the middle frame 120, thereby preventing the FPC 150 from warping and increasing the connection stability.

[0059] Considering the different models of electronic devices, the position of the small board connector 141 may not be fixed, and there may be a deviation within a certain range (such as 0.5mm on the left and right), which may cause the FPC 150 to be unable to adapt to different models. To address this problem, the present application allows a certain range of deviation by setting each connecting section or each bending section of the first connecting portion 151 in a straightened / relaxed state, so that it can adapt to electronic devices of various models.

[0060] In some examples, such as Figure 5 As shown, the first connecting segment 1511 and the second connecting segment 1513 can be parallel to the plane where the small board 140 is located, and the first bending segment 1512 can be perpendicular to the plane where the small board 140 is located. It should be understood that when the distance between the position where the small board 140 is electrically connected to the first connecting portion 151 (or the position of the small board connector 141) and the battery 160 is far, each connecting segment (such as the first connecting segment 1511 and the second connecting segment 1513) and each bending segment (such as the first bending segment 1512) of the first connecting portion 151 can be in a taut state, so that it can be compatible with multiple sizes and realize the electrical connection between the first connecting portion 151 and the small board 140.

[0061] In other examples, such as Figure 6 As shown, the first bending section 1512 may have a plurality of bending portions or bending regions. It should be understood that when the distance between the position where the small board 140 is electrically connected to the first connecting portion 151 (or the position of the small board connector 141) and the battery 160 is relatively close, the first connecting portion 151 may grow a portion. In the present application, the grown portion may be retracted within the first bending section 1512, and the first bending section 1512 absorbs the excess portion, thereby being compatible with multiple sizes and realizing the electrical connection between the first connecting portion 151 and the small board 140.

[0062] It should be understood that in the present application, a deviation within a preset range (such as 0.5 mm) can be allowed. When the FPC 150 is relatively long, the excess length can be set at the bent portion of the first connection portion 151 (such as the first bent section 1512), that is, the extended portion can be accommodated in the bent portion of the first connection portion 151; when the FPC 150 is relatively short, the length of the bent portion of the first connection portion 151 (such as the first bent section 1512) can be compressed, such as making the first bent section 1512 straight, thereby increasing the length of the first connection section 1511. In other words, the structure of the FPC 150 provided in the present application can be applied to a variety of models, solve the requirement for high length precision of the FPC 150, and can achieve compatibility with a variety of screens of the same size.

[0063] The FPC 150 may further include a second connection portion 152, and the second connection portion 152 is used to be electrically connected to the display screen 110. For example, Figure 4As shown, one end of the second connection portion 152 can be electrically connected to the main body 154 , and the other end of the second connection portion 152 can be bent toward the display screen 110 and electrically connected to the display screen 110 .

[0064] The FPC 150 may further include a third connection portion 153, which may be used to electrically connect to a mainboard (not shown in the figure). Figure 4 As shown, the third connection portion 153 may include a third bending section 1531 and a fourth connection section 1532, the third bending section 1531 is connected between the main body 154 and the fourth connection section 1532, the third bending section 1531 bends and extends toward the back cover 130, and the fourth connection section 1532 is electrically connected to the main board.

[0065] Exemplarily, the third connection portion 153 can be electrically connected to the mainboard via a mainboard connector. For example, the mainboard connector can be located on a side of the mainboard away from the display screen 110, and the fourth connection segment 1532 of the third connection portion 153 can be connected to a side of the mainboard connector away from the display screen 110. The electrical connection between the third connection portion 153 of the FPC 150 and the mainboard can be achieved through the mainboard connector, the third bending segment 1531, and the fourth connection portion 1532.

[0066] It should be understood that the first connection portion 151 , the second connection portion 152 , and the third connection portion 153 of the FPC 150 can respectively achieve electrical connection with the small board 140 , the display screen 110 , and the main board.

[0067] In some examples, combined Figure 2 and Figure 4 As shown, the first connection part 151 and the second connection part 152 can be arranged at one end of the main body 154, and the third connection part 153 can be arranged at the other end of the main body 154. In the present application, considering that the sizes of the main board and the small board 140 inside the electronic device 100 are different, and the size of the small board 140 is generally smaller than that of the main board, the first connection part 151 and the second connection part 152 can be arranged at one end of the main body 154, and the third connection part 153 can be arranged at the other end of the main body 154, so that the internal space of the electronic device 100 can be fully utilized.

[0068] In some examples, combined Figure 2 and Figure 4As shown, the first connection portion 151 and the second connection portion 152 can be arranged near the bottom (lower part) of the electronic device 100, and the third connection portion 153 can be arranged near the top (upper part) of the electronic device 100.
