[0017] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.
[0018] Reference below Figure 1-Figure 3 An electronic device 1000 according to an embodiment of the present application is described. Here, the electronic device 1000 may be a mobile phone, a tablet computer, a notebook computer, or a wearable device.
[0019] like Figure 1-Figure 2 As shown, the electronic device 1000 of the present application includes a middle frame 100, a display screen assembly 200, a flexible circuit board 300 and a main board 400. It should be noted that the middle frame 100 can be used to support the display screen assembly 200 and the main board 400. The display screen assembly 200 can display the signal of the electronic device 1000 in the form of text or images, etc., so that the user can read it easily. The flexible circuit board 300 can be used to conduct signals and currents.
[0020] Specifically, refer to Figure 2 The middle frame 100 has a through hole 110. The display screen assembly 200 is located on one side of the middle frame 100. One end of the flexible circuit board 300 is electrically connected to the display screen assembly 200, the flexible circuit board 300 is inserted into the through hole 110, and the other end of the flexible circuit board 300 has a first connection seat 310. Figure 3 As shown, the flexible circuit board 300 may include a folding section 320, which is located on the other side of the middle frame 100. The main board 400 is located on the other side of the middle frame 100, and the folding section 320 bypasses the main board 400 and overlaps with the main board 400. The main board 400 is provided with a second connection socket, which is electrically connected to the first connection socket 310, so that the display screen assembly 200 can be electrically connected to the main board 400 using the flexible circuit board 300.
[0021] It is understandable that the mainboard 400 can be electrically connected to the first connection socket 310 through the second connection socket to transmit signals and currents to the flexible circuit board 300, and the flexible circuit board 300 is electrically connected to the display screen assembly 200, and the display screen assembly 200 can present the signal to the user in the form of text or images. The middle frame 100 is provided with a through hole 110 and the flexible circuit board 300 is provided with a folding section 320 to facilitate the flexible circuit board 300 to pass from one side of the middle frame 100 to the other side of the middle frame 100, thereby optimizing the overall structure of the electronic device 1000 and reducing the product volume.
[0022] According to the electronic device 1000 of the present application, by setting a via hole 110 on the middle frame, the flexible circuit board 300 is passed through the via hole 110, and the folded section 320 of the flexible circuit board 300 bypasses the main board 400 to overlap with the main board 400, so that the flexible circuit board 300 can be directly connected to the main board 400, thereby shortening the length of the flexible circuit board 300.
[0023] like Figure 3 As shown, the main board 400 has a through groove 410. In the thickness direction of the main board 400, the through groove 410 penetrates the main board 400, the flexible circuit board 300 is inserted into the through groove 410, and the folding section 320 bypasses the wall of the through groove 410 to overlap with the main board 400. It can be understood that the through groove 410 can provide a penetration space for the folding section 320, so as to facilitate the electrical connection and overlap between the folding section 320 and the main board 400, thereby facilitating the plugging of the first connecting seat 310 of the flexible circuit board 300 and the second connecting seat of the main board 400. In addition, the through groove 410 can also limit the flexible circuit board 300, thereby preventing the flexible circuit board 300 from shaking. Further, referring to Figure 3 The through groove 410 is provided at the edge of the main board 400 , and the through groove 410 is open toward one side of the edge of the main board 400 , thereby facilitating the folding section 320 to bypass the through groove 410 and overlap with the main board 400 .
[0024] like Figure 3 As shown, the electronic device 1000 may also include a first seal. The first seal is disposed in the through groove 410, and the first seal is sealed and connected to the flexible circuit board 300. On the one hand, the first seal can prevent the flexible circuit board 300 from shaking in the through groove 410; on the other hand, the first seal can also play a waterproof role, preventing the electronic device 1000 from flowing from the through groove 410 to the display screen assembly 200 or the main board 400 after water enters the through groove 410. Further, the peripheral wall of the first seal has a first sealing groove, and the side wall of the through groove 410 is disposed in the first sealing groove, thereby not only making the first sealing groove stably installed in the through groove 410, but also improving the sealing performance of the first seal.
[0025] refer to Figure 3The via hole 110 is directly opposite to the through groove 410, and the portion of the flexible circuit board 300 located in the via hole 110 and the through groove 410 extends in a straight line, thereby facilitating the flexible circuit board 300 to pass through the via hole 110 and the through groove 410, so that the flexible circuit board 300 can electrically connect the display screen assembly 200 and the main board 400 on both sides of the middle frame 100.
[0026] Combination Figure 3 , the folding section 320 may include a first section 321 and a second section 322. The extension direction of the first section 321 is perpendicular to the plane where the mainboard 400 is located. The second section 322 is connected to the first section 321, and the extension direction of the second section 322 is parallel to the plane where the mainboard 400 is located. The first connecting seat 310 is provided in the second section 322. It can be understood that the first section 321 and the second section 322 can change the extension direction of the flexible circuit board 300, and guide the flexible circuit board 300 from one side of the middle frame 100 to the other side of the middle frame 100, thereby, the first connecting seat 310 on the second section 322 can be overlapped on the mainboard 400, so that the flexible circuit board 300 can electrically connect the mainboard 400 and the display screen assembly 200 located on both sides of the middle frame 100.
[0027] refer to Figure 3 The first section 321 and the second section 322 are connected in a smooth transition. The smooth transition connection can avoid the connection between the first section 321 and the second section 322 and the main board 400 from damaging the main board 400, thereby facilitating the bypass of the main board 400 and the overlap of the main board 400. Furthermore, the folding section 320 can also be in an arc shape to bypass the main board 400. The arc-shaped folding section 320 can not only reduce the probability of the folding section 320 damaging the main board 400 when bypassing the main board 400; the arc-shaped structure can also avoid stress concentration when the flexible circuit board 300 is bent, thereby protecting the flexible circuit board 300.
[0028] The display screen assembly 200 may have a first edge and a second edge adjacent to each other, and the first edge and the second edge extend in different directions. The flexible circuit board 300 includes a third section and a fourth section. One end of the third section is electrically connected to the display screen assembly 200, and the third section extends along the first edge, thereby facilitating the electrical connection of the third section to the first edge, and further facilitating the electrical connection of the flexible circuit board 300 to the display screen assembly 200. One end of the fourth section is electrically connected to the other end of the third section, and the other end of the fourth section is electrically connected to the folding section 320, and the fourth section extends along the second edge. Since the folding section 320 is electrically connected to the main board 400, the flexible circuit board 300 electrically connects the display screen assembly 200 to the main board 400, so that the main board 400 can conduct signals and currents to the display screen assembly 200.
[0029] like Figure 3As shown, the electronic device 1000 may further include a second seal. The second seal may be disposed in the via hole 110, and the second seal is connected to the flexible circuit board 300. On the one hand, the second seal may prevent the flexible circuit board 300 from shaking in the via hole 110; on the other hand, the second seal may also play a waterproof role, preventing water from flowing from the via hole 110 to the display assembly 200 or the main board 400 after the electronic device 1000 is flooded.
[0030] Furthermore, the peripheral wall of the second seal has a second sealing groove, and the peripheral wall of the via 110 is arranged in the second sealing groove, thereby not only the second seal can be stably installed in the via 110, but also the sealing performance of the second seal can be improved. Furthermore, the second seal can be a rubber part. It should be noted that the rubber part has the advantages of good elasticity and low cost. Using a rubber part as the second seal can not only facilitate the installation of the second seal in the via 110, but also save the cost of the electronic device 1000.
