[0020] Combine the following Figure 1-Figure 5 An electronic device according to an embodiment of the present application is described.

[0021] like Figure 1 As shown, an electronic device according to some embodiments of the present application includes: a frame 1, the frame 1 includes an insulating frame 10 and a metal frame 12, the insulating frame 10 is arranged on the inner side of the metal frame 12 and connected to the metal frame 12, and the metal frame 12 includes an antenna 18; a circuit board 2, arranged on the inner side of the insulating frame 10; a metal conductive member 3, the metal conductive member 3 is arranged on the insulating frame 10, and the first end 30 of the metal conductive member 3 is electrically connected to the metal frame 12, and the second end 32 of the metal conductive member 3 is electrically connected to the circuit board 2, so that the antenna 18 is electrically connected to the circuit board 2 through the metal conductive member 3.

[0022] In an embodiment of the present application, the electronic device includes a frame 1, a circuit board 2 and a metal conductive member 3. The frame 1 includes a metal frame 12 and an insulating frame 10. The insulating frame 10 is arranged on the inner side of the metal frame 12, so that the electronic device has a metal appearance and good wear resistance. At the same time, it is also possible to realize the production of complex structures on the insulating frame 10, and the waterproof performance of the electronic device can be improved. The circuit board 2 is arranged on the inner side of the insulating frame 10, and the metal conductive member 3 is arranged on the insulating frame 10, and the first end 30 of the metal conductive member 3 is electrically connected to the metal frame 12, and the second end 32 of the metal conductive member 3 is electrically connected to the circuit board 2, so that the antenna 18 on the metal frame 12 can be electrically connected to the circuit board 2 through the metal conductive member 3, thereby realizing the relevant functions of the antenna 18 of the electronic device.

[0023] Meanwhile, the metal frame 12 includes an antenna 18 . For example, a portion of the metal frame 12 is constructed as the antenna 18 , so that the antenna 18 will not be blocked by other components, thereby improving the performance of the antenna 18 .

[0024] Specifically, the first end 30 of the metal conductive member 3 is electrically connected to the feeding point of the antenna 18 .

[0025] Optionally, the antenna 18 can implement an ESIM (Embedded-SIM) function.

[0026] Optionally, the insulating frame 10 is a plastic frame.

[0027] Optionally, the frame 1 is ring-shaped.

[0028] According to some embodiments of the present application, optionally, the insulating frame 10 is an injection-molded part, the metal conductive part 3 is embedded in the insulating frame 10 , and the first end 30 and the second end 32 are exposed from the insulating frame 10 .

[0029] In this embodiment, the insulating frame 10 is an injection molded part, and the metal conductive part 3 is embedded in the insulating frame 10, so that the metal conductive part 3 can be molded with the insulating frame 10 by insert injection molding, the processing efficiency is high, and the connection strength between the metal conductive part 3 and the insulating frame 10 is high, which can avoid the problem of abnormal noise caused by the shaking of the metal conductive part 3 in the frame body 1. Among them, the first end 30 and the second end 32 are exposed in the insulating frame 10, so that the first end 30 can be electrically connected to the metal frame 12, and the second end 32 can be electrically connected to the circuit board 2, so that no secondary processing is required, reducing the manufacturing cost.

[0030] like Figure 1 As shown, according to some embodiments of the present application, optionally, a spring sheet 4 is provided between the first end 30 and the metal frame 12 , and the first end 30 and the metal frame 12 are electrically connected via the spring sheet 4 .

[0031] In this embodiment, a spring 4 is provided between the first end 30 of the metal conductive member 3 and the metal frame 12, so as to realize the electrical connection between the metal conductive member 3 and the metal frame 12. The spring 4 is elastic, and under the effect of the elasticity, the metal conductive member 3 and the metal frame 12 can be reliably electrically connected, so as to avoid the disconnection between the two and affect the signal of the antenna 18.

[0032] In addition, when the metal conductive part 3 and the insulating frame 10 are insert-molded, the metal conductive part 3 generally does not protrude from the insulating frame 10. Therefore, the setting of the spring piece 4 can connect the first end 30 exposed in the insulating frame 10 to the metal frame 12, thereby eliminating the need for secondary processing of the insulating frame 10 to achieve the connection between the metal conductive part 3 and the metal frame 12.

[0033] It can be understood that the spring piece 4 is a metal piece.

[0034] According to some embodiments of the present application, optionally, the spring piece 4 is connected to the metal frame 12 by welding, or the spring piece 4 is connected to the first end 30 by welding.

[0035] In this embodiment, the spring piece 4 is welded to the metal frame 12 , or welded to the first end 30 , so as to improve the reliability of the electrical connection between the metal frame 12 and the metal conductive member 3 .

[0036] Optionally, the spring sheet 4 is welded to the metal conductive member 3 by spot welding, or the spring sheet 4 is welded to the metal frame 12 by spot welding. Optionally, one end of the spring sheet 4 is welded to the first end 30 of the metal conductive member 3, and the other end of the spring sheet 4 is a free end and has an angle with the first end 30 of the metal conductive member 3. After the insulating frame 10 and the metal frame 12 are assembled, the other end of the spring sheet 4 abuts against the metal frame 12.

[0037] Optionally, the welding of the spring piece 4 has a direction requirement: the direction of the opening of the spring piece 4 needs to be designed along the assembly direction of the metal frame 12 and the plastic frame to avoid scratches during assembly.

[0038] like Figure 1 and Figure 5 As shown, according to some embodiments of the present application, optionally, the metal conductive member 3 includes at least one bending structure 34 , and the at least one bending structure 34 is located between the first end 30 and the second end 32 .

[0039] In this embodiment, the metal conductive member 3 includes at least one bending structure 34, which increases the overall length of the metal conductive member 3, thereby increasing the contact area between the metal conductive member 3 and the insulating frame 10, so that the metal conductive member 3 is reliably embedded in the insulating frame 10, and the connection strength between the metal conductive member 3 and the insulating frame 10 is improved. At the same time, the bending arrangement of the metal conductive member 3 can also realize the electrical connection of the contact surfaces in different directions, thereby realizing the electrical connection between the antenna 18 of multiple frequency bands and the circuit board 2. In addition, the increase in the length of the metal conductive member 3 also increases the waterproof path at the metal conductive member 3, thereby increasing the waterproof effect.

[0040] It can be understood that the metal conductive member 3 is formed by bending for multiple times.

[0041] like Figure 3 and Figure 4 As shown, according to some embodiments of the present application, optionally, a side wall of the insulating frame 10 is provided with a through hole 14 , and the first end 30 is passed through the through hole 14 and connected to the metal frame 12 .

[0042] In this embodiment, a through hole 14 is provided on the side wall of the insulating frame 10, and the first end 30 of the metal conductor 3 is inserted into the through hole 14, so that the first end 30 of the metal conductor 3 can be directly electrically connected to the metal frame 12, and there is no need to use other metal parts to connect the metal conductor 3 and the metal frame 12, thereby reducing the manufacturing cost.

[0043] like Figure 3 As shown, according to some embodiments of the present application, optionally, a connection between the first end 30 and the metal frame 12 is covered with a waterproof member 16 ; wherein the waterproof member 16 is located in the through hole 14 to seal the through hole 14 .

[0044] In this embodiment, the connection between the first end 30 of the metal conductive member 3 and the metal frame 12 is covered with a waterproof member 16, which can waterproof and seal the connection between the metal conductive member 3 and the metal frame 12, thereby preventing sweat or other liquids from entering the connection between the first end 30 of the metal conductive member 3 and the metal frame 12, thereby preventing the connection between the metal conductive member 3 and the metal frame 12 from being corroded, resulting in failure of the connection between the metal conductive member 3 and the metal frame 12. At the same time, the waterproof member 16 is located in the through hole 14, so that the waterproof member 16 can block the through hole 14, thereby preventing external liquid from entering the interior of the frame 1 through the through hole 14.

[0045] Optionally, the waterproof member 16 includes waterproof glue or a waterproof rubber member or a waterproof silicone member or a waterproof membrane.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, according to some embodiments of the present application, optionally, the electronic device also includes: a locking piece 5, which is sequentially passed through the circuit board 2, the second end 32 and the insulating frame 10, and is connected to the insulating frame 10 so that the second end 32 is clamped between the insulating frame 10 and the circuit board 2.

[0047] In this embodiment, the electronic device also includes a locking piece 5, and the second end 32 of the metal conductor 3 is connected to the circuit board 2 through the locking piece 5, so that the second end 32 of the metal conductor 3 is fixed on the circuit board 2, thereby ensuring the reliability of the connection between the second end 32 of the metal conductor 3 and the circuit board 2.

[0048] Optionally, the locking member 5 comprises a screw.

[0049] Optionally, a first mounting hole is provided on the circuit board 2, and a second mounting hole is provided on the insulating frame 10. The second mounting hole passes through the second end 32 of the metal conductive member 3. The locking member 5 is inserted into the first mounting hole and the second mounting hole, so that the second end 32 of the metal conductive member 3 is tightly attached to the circuit board 2, thereby realizing the connection between the metal conductive member 3 and the circuit board 2.

[0050] Optionally, the second mounting hole is a threaded hole.

[0051] like Figure 1 and Figure 3 As shown, according to some embodiments of the present application, optionally, the electronic device also includes: a screen 6, which is arranged on the first side of the frame 1; a bottom shell 7, which is arranged on the second side of the frame 1, the first side and the second side are arranged opposite to each other, the screen 6, the bottom shell 7 and the insulating frame 10 enclose an installation cavity 70, and the circuit board 2 is arranged in the installation cavity 70; wherein, the insulating frame 10 and the screen 6 are adhesively connected, and the insulating frame 10 and the bottom shell 7 are adhesively connected.

[0052] In this embodiment, the electronic device further includes a screen 6 and a bottom shell 7, wherein the screen 6 is arranged on a first side of the frame 1, and the bottom shell 7 is arranged on a second side of the frame 1, and the screen 6 and the bottom shell 7 are respectively located on opposite sides of the frame 1, so that the screen 6, the bottom shell 7 and the insulating frame 10 enclose a mounting cavity 70 for mounting the circuit board 2 and other components. The insulating frame 10 is bonded to the screen 6, thereby realizing the connection between the insulating frame 10 and the screen 6 and the sealing of the gap, and the insulating frame 10 is bonded to the bottom shell 7, thereby realizing the connection between the insulating frame 10 and the bottom shell 7 and the sealing of the gap.

[0053] Optionally, the insulating frame 10 and the screen 6 are sealed and connected via a waterproof sealant, and the insulating frame 10 and the bottom shell 7 are sealed and connected via a waterproof sealant.

[0054] Optionally, waterproof sealant is provided along the circumference of the insulating frame 10 and the screen 6 , and waterproof sealant is provided along the circumference of the insulating frame 10 and the bottom shell 7 .

[0055] According to some embodiments of the present application, optionally, the insulating frame 10 is bonded to the metal frame 12 .

[0056] In this embodiment, the insulating frame 10 and the metal frame 12 are bonded together, which simplifies the connection process between the metal frame 12 and the insulating frame 10 and further reduces the manufacturing cost.

[0057] According to some embodiments of the present application, optionally, the metal shell (e.g., metal frame 12) is first subjected to a simple CNC machine tool (Computerized Numerical Control, CNC), and then the plastic middle frame (e.g., insulating frame 10) that has been injection molded is glued on the side so that the metal shell and the plastic middle frame are bonded together by glue. The plastic middle frame is fixed to the display screen (e.g., screen 6) and the bottom shell 7 by glue, and the glue also plays a waterproof role. In this way, the metal conductive part 3 does not need to participate in the waterproofing of the entire machine, and the solution is simple and reliable.

[0058] The metal shell and the plastic middle frame are assembled and fixed together by glue. However, the glue is not a complete circle and cannot provide waterproofing. External water or sweat may enter between the metal shell and the plastic middle frame.

[0059] Optionally, the metal conducting member 3 is formed by processing with stainless steel and then fixed by insert injection molding, which has relatively high processing efficiency and reliable structure.

[0060] Optionally, one side of the metal conductive member 3 is connected to the metal housing, such as Figure 1As shown, a spring 4 is spot welded on the metal conductive member 3, and the spring 4 is connected to the metal shell. In this embodiment, the spring 4 can also be spot welded on the metal shell. The other side of the metal conductive member 3 is connected to the printed circuit board 2 (PCB), which can realize the function of the feed point of the antenna 18. In this embodiment, the metal conductive member 3 is directly locked on the PCB by screws.

[0061] Optionally, the stainless steel can be bent and formed multiple times to effectively achieve electrical connection of contact surfaces in different directions. At the same time, because the bonding force of the insert injection molding is general, in order to ensure a better waterproof effect, the waterproof path needs to be designed to be as long as possible.

[0062] Because the insert injection molding requires a relatively large thickness of the steel sheet, and the spring sheet 4 used for electrical connection needs to be elastic and thin. Here, the spring sheet 4 is spot-welded on the stainless steel surface to achieve these two functions.

[0063] The welding of the spring piece 4 has a directional requirement: the direction of the opening of the spring piece 4 needs to be designed along the direction of the metal shell assembly to avoid scratching during assembly.

[0064] In this embodiment, the metal middle frame solution for the metal patch can realize the metal feed point solution in which the antenna 18 is directly connected to the circuit board 2 (such as the mainboard). Thus, the ESIM function can be realized. Antennas 18 of other frequency bands can also be realized by this solution, which reduces the difficulty of debugging and improves the performance of the antenna 18 of the whole machine.

[0065] According to some embodiments of the present application, optionally, a through hole 14 is opened on the plastic middle frame, and the metal conductive piece 3 can be directly welded to the metal shell for conduction, which can save a spring 4, improve reliability, reduce the number of processes, and reduce costs.

[0066] Optionally, a layer of waterproof glue is added to the welding area to seal the plastic middle frame and the metal shell, which can not only protect the welding area, but also play a role in waterproofing the entire machine and prevent water from entering the interior of the entire machine through the metal shell and the through hole 14.

[0067] The other side of the metal conductive member 3 is connected to the main board. In this embodiment, it is fixed to the PCB by screws.

[0068] In this embodiment, a through hole 14 is provided on the plastic middle frame to facilitate the assembly of the metal conductive part 3 and the waterproof layer. The metal middle frame solution for the metal patch can realize the metal feed point solution in which the antenna 18 is directly connected to the mainboard, thereby realizing the ESIM function. At the same time, antennas 18 of other frequency bands can also be realized with this solution, which reduces the difficulty of debugging and improves the performance of the antenna 18 of the whole machine. The whole machine can be waterproofed to a level of more than 5 atmospheres (ATM), ensuring the reliability of the contact of the antenna 18.

[0069] Optionally, the electronic device includes wearable devices such as watches and bracelets, and may also include other electronic devices with metal casings, such as headphones, mobile phones, tablet computers, etc.
