[0026] Currently, many electronic devices adopt foldable designs to enhance their portability. These devices typically consist of two rotating frames, each with a cable hole for a flexible printed circuit board (FPCB) to pass through, thereby electrically connecting the components within the two frames. To prevent liquid from entering the frames through the cable hole, seals are typically installed in these holes. However, in practice, these seals provide poor sealing performance and fail to meet the sealing requirements of electronic devices.

[0027] To solve the above problems, the present invention provides an electronic device. It should be noted that the electronic device mentioned in the present invention can be a laptop computer, a foldable mobile phone, or a game console, and the present invention does not limit this. In one possible implementation of the present invention, the electronic device is a foldable mobile phone.

[0028] Reference Figure 1 、 Figure 2 and Figure 3The electronic device includes a first frame 1, a second frame 2, a rotating assembly, a flexible circuit board 3, a first fixing assembly 4 and a first sealing member 5; the first frame 1 has a first wire-passing hole 11, a first target element 12 is fixed in the first frame 1, and a second target element 22 is fixed in the second frame 2; the first frame 1 is rotatably connected to the second frame 2 through the rotating assembly so that the electronic device can be switched between an unfolded state and a folded state; a first end of the flexible circuit board 3 is electrically connected to the first target element 12, the flexible circuit board 3 spans the rotating assembly, and a second end of the flexible circuit board 3 is electrically connected to the second target element 22; the first fixing assembly 4 is located in the first wire-passing hole 11 to fix the first target part 31 of the flexible circuit board 3 located in the first wire-passing hole 11; the first sealing member 5 is located in the first wire-passing hole 11 to fill the gap between the first target part 31 and the first fixing assembly 4, and the gap between the first fixing assembly 4 and the first wire-passing hole 11.

[0029] In the embodiments of the present application, the structural design of the first frame 1 and the second frame 2 is related to the type of electronic device. For example, if the electronic device is a laptop computer, the first frame 1 may be the housing of the system portion of the laptop computer, and the second frame 2 may be the housing of the display portion of the laptop computer. If the electronic device is a foldable mobile phone, the first frame 1 may be the housing of the first display portion of the foldable mobile phone, and the second frame 2 may be the housing of the second display portion of the foldable mobile phone.

[0030] In the embodiment of the present application, the first target element 12 and the second target element 22 are important components for maintaining the normal operation of the electronic device. Therefore, there are many possibilities for the structural design of the first target element 12 and the second target element 22. For example, the first target element 12 can be a central processing unit (CPU) and the second target element 22 can be a sensor; or, the first target element 12 can be a graphics processing unit (GPU) and the second target element 22 can be a random access memory (RAM). The embodiment of the present application does not impose any restrictions on this.

[0031] In the technical solution provided by the embodiment of the present application, the electronic device includes a first frame 1, a second frame 2, a rotating assembly, a flexible circuit board 3, a first fixing assembly 4 and a first sealing member 5. The first frame 1 and the second frame 2 are rotatably connected by the rotating assembly, so that the first frame 1 and the second frame 2 can rotate relative to each other, thereby realizing the switching of the electronic device between an unfolded state and a folded state. A first end of the flexible circuit board 3 is electrically connected to a first target element 12 in the first frame 1. The flexible circuit board 3 spans the rotating assembly, and a second end of the flexible circuit board 3 is electrically connected to a second target element 22 in the second frame 2. Such that signals can be transmitted between the first target element 12 and the second target element 22, thereby ensuring the normal operation of the electronic device. The first fixing assembly 4 is located in the first wire-passing hole 11 to fix the first target portion 31 of the flexible circuit board 3 located in the first wire-passing hole 11. The first sealing member 5 is located in the first wire-passing hole 11 to fill the gap between the first target portion 31 and the first fixing assembly 4, and between the first fixing assembly 4 and the first wire-passing hole 11. When assembling an electronic device, the first end of the flexible circuit board 3 can be passed through the first wire hole 11 first; then the first fixing component 4 can be installed in the first wire hole 11 to fix the first target part 31 in the first wire hole 11; finally, the first sealing member 5 can be installed in the first wire hole 11 to fill the gap between the first target part 31 and the first fixing component 4, and between the first fixing component 4 and the first wire hole 11. Here, the first target part 31 is fixed by the first sealing assembly. When the electronic device switches states, the first target part 31 can be prevented from swinging in the first wire passing hole 11, thereby avoiding wear of the first seal 5 in the first wire passing hole 11 and extending the service life of the first seal 5; the first seal 5 is installed in the first wire passing hole 11. On the one hand, the first wire passing hole 11 can provide a larger accommodating space for the first seal 5, so that the first seal 5 can form a thicker sealing surface in the extension direction of the first wire passing hole 11, thereby improving the sealing effect of the first seal 5; on the other hand, the first seal 5 can contact the inner wall of the first wire passing hole 11 in the first wire passing hole 11, so that the first seal 5 can have a sufficient attachment area, reducing the probability of the first seal 5 slipping out of the first wire passing hole 11 and improving the reliability of the first seal 5 when in use.

[0032] In the embodiment of the present application, the function of the first fixing component 4 is to fix the first target part 31 on the flexible circuit board 3 located in the first wire hole 11. Therefore, the structural design of the first fixing component 4 has many possibilities. For example, the first fixing component 4 may include a support member and an adhesive member. The support member has a fixing part and a supporting part. The support member is installed in the first wire hole 11 through the fixing part, and the adhesive member is arranged on the supporting part for bonding and fixing the first target part 31.

[0033] Reference Figure 1and Figure 3 In one possible embodiment of the present application, the first fixing assembly 4 includes a first clamping member 41 and a second clamping member 42 arranged opposite to each other. The two opposite side walls of the first target portion 31 along its thickness direction respectively abut against the two opposite side walls of the first clamping member 41 and the second clamping member 42, so as to fix the first target portion 31 between the first clamping member 41 and the second clamping member 42. Here, the two opposite side walls of the first target portion 31 along its thickness direction respectively abut against the two opposite side walls of the first clamping member 41 and the second clamping member 42. On the one hand, the first target portion 31 can be limited in the thickness direction, thereby achieving fixation of the first target portion 31; on the other hand, the first clamping member 41 and the second clamping member 42 are in surface contact with the first target portion 31, which can reduce damage to the first target portion 31 during the fixing process.

[0034] In the embodiment of the present application, the two opposite side walls of the first clamping member 41 and the second clamping member 42 can be arranged in parallel or at an angle, and the embodiment of the present application does not limit this. In a possible embodiment of the present application, the first clamping member 41 has a first clamping surface, the second clamping member 42 has a second clamping surface, the first clamping surface and the second clamping surface are arranged opposite to each other, and the first clamping surface and the second clamping surface are parallel to each other; the two opposite side walls of the first target portion 31 along its thickness direction are respectively abutted against the first clamping surface and the second clamping surface. Here, the first clamping surface and the second clamping surface are arranged opposite to and in parallel, which can increase the contact area between the first clamping member 41, the second clamping member 42 and the first target portion 31, and while having a better limiting effect on the first target portion 31, it can also further reduce damage to the first target portion 31 during the fixing process.

[0035] In the embodiments of the present application, the first fixing component 4 and the first frame 1 may be fixed in various ways. For example, the first fixing component 4 may be integrally connected to the first frame 1. In one possible embodiment of the present application, the first fixing component 4 is provided with a connecting structure, and the first frame 1 is provided with a mating structure that is detachably connected to the connecting structure. During use of the electronic device, the flexible printed circuit board 3 is easily damaged due to excessive bending. The detachable connection between the first fixing component 4 and the first frame 1 makes it easier to disassemble and assemble the flexible printed circuit board 3, thereby improving the convenience of maintenance and repair of the electronic device.

[0036] In the embodiment of the present application, the structural forms of the connection structure and the matching structure are possible in many ways. For example, the connection structure may include a fixing plate and a fastener. The fixing plate is provided on the first fixing component 4 and has a connection hole. The matching structure includes a threaded hole provided on the first frame 1. When installing the first fixing component 4, the connection hole on the fixing plate can be aligned with the threaded hole on the first frame 1, and then the fastener can be passed through the connection hole and the threaded hole in sequence to achieve the installation of the first fixing component 4. Figure 1 and Figure 3 In a possible embodiment of the present application, the connection structure includes a hook 411, the hook 411 is located on the first clamping member 41, the second clamping member 42 is detachably connected to the first clamping member 41, and the matching structure includes a connecting protrusion that is engaged with the hook 411. In this way, when installing the first fixing component 4, the second clamping member 42 can be detachably connected to the first clamping member 41 first, and then the hook can be engaged with the connecting protrusion on the first frame 1, which is more convenient to install. It should be noted that elastic deformation will occur when the hook is engaged with the connecting protrusion. In order to improve the matching effect of the hook and the connecting protrusion, refer to Figure 1 , an avoidance portion 412 can be provided on the first clamping member 41 to provide an avoidance space for deformation of the hook.

[0037] Reference Figure 1 and Figure 3 In one possible embodiment of the present application, the electronic device further includes an adhesive member 43, which is bonded between the first target portion 31 and the second clamping member 42. Thus, when installing the flexible circuit board 3, the first target portion 31 and the second clamping member 42 can first be bonded together using the adhesive member 43, and then the second clamping member 42 can be removably connected to the first clamping member 41. Finally, the flexible circuit board 3 and the first fixing assembly 4 can be integrally installed into the first wire hole 11, resulting in highly efficient installation. Furthermore, the provision of the adhesive member 43 can increase the firmness between the first target portion 31 and the first fixing assembly 4, thereby improving the reliability of the electronic device during use.

[0038] Reference Figure 2 and Figure 3 In the embodiment of the present application, the electronic device includes a rear cover plate 8 connected to the first frame body 1. The angle between the extension direction of the first cable hole 11 and the plane of the rear cover plate 8 is acute. This allows the length of the first cable hole 11 to be extended without increasing the thickness of the electronic device, thereby providing more space for the first sealing member 5 and further thickening the sealing surface of the first sealing member 5 in the direction in which the first cable hole 11 extends.

[0039] It should be noted that in the embodiment of the present application, there are many possible values ​​of the angle between the extension direction of the first wire hole 11 and the plane where the rear cover plate 8 is located. For example, the angle between the extension direction of the first wire hole 11 and the plane where the rear cover plate 8 is located can be 30°, 45°, or 80°, and the embodiment of the present application does not limit this.

[0040] In the embodiment of the present application, the function of the rear cover 8 is to block the opening on the first frame 1 to ensure the sealing of the first frame 1. Figure 1 and Figure 3 The first wire-passing hole 11 is provided on the side wall of the first frame 1. In this way, the first wire-passing hole 11 does not occupy the area on the first frame 1 for bonding with the rear cover 8, so that the rear cover 8 and the first frame 1 have a larger bonding area, thereby improving the bonding strength of the rear cover 8 and the first frame 1.

[0041] Reference Figure 2 and Figure 3 In the embodiment of the present application, in the direction close to the rear cover 8, the first wire hole 11 includes a first section 111 and a second section 112 that are connected in sequence. The first fixing component 4 is located in the first section 111, and the first sealing component 5 is located in the second section 112. During the use of the electronic device, because the rotating component includes more relatively movable parts, the sealing performance of the rotating component is poor. The first fixing component 4 is located in the first section 111, and the first sealing component 5 is located in the second section 112. In this way, when liquid penetrates into the interior of the rotating component, the first fixing component 4 can form a water barrier in front of the first sealing component 5, making it difficult for the liquid to contact the first sealing component 5, further improving the sealing performance of the electronic device.

[0042] In the embodiment of the present application, the first sealing member 5 is used to fill the gaps between the first target portion 31 and the first fixing assembly 4, and between the first fixing assembly 4 and the first wire hole 11. Therefore, the first sealing member 5 has various structural possibilities. For example, the first sealing member 5 may include a sealing ring or a sealing packing, which is not limited in the embodiment of the present application.

[0043] In a possible embodiment of the present application, the first sealing member 5 includes a sealant, which is poured into the first wire-passing hole 11 to fill the gaps between the first target portion 31 and the first fixing component 4, and between the first fixing component 4 and the first wire-passing hole 11. In this way, when setting the first sealing member 5, the sealant can be directly poured into the first wire-passing hole 11, which is relatively simple to operate. In addition, the sealant has good fluidity. After the sealant is poured into the first wire-passing hole 11, the sealant can actively fill the holes and gaps to form a uniform sealing surface. In addition, the sealant also has the characteristic of strong adhesion. The sealant can form a firm bond with the hole wall of the first wire-passing hole 11, reducing the risk of sealing failure.

[0044] Reference Figure 1 and Figure 2 In an embodiment of the present application, the electronic device further includes a second fixing component 6 and a second sealing component 7. The second frame 2 has a second wire-passing hole 21. The second fixing component 6 is located in the second wire-passing hole 21 to fix the second target portion 32 on the flexible circuit board 3 located in the second wire-passing hole 21. The second sealing component 7 is located in the second wire-passing hole 21 to fill the gap between the second target portion 32 and the second fixing component 6, and the second fixing component 6 and the second wire-passing hole 21. The flexible circuit board 3 also has a third target portion 33 located between the first target portion 31 and the second target portion 32. The third target portion 33 has a target coating, and the third target portion 33 has a first state and a second state. When the electronic device is switched to a folded state, the third target portion 33 is in the first state, and when the electronic device is switched to an unfolded state, the third target portion 33 is in the second state, wherein the looseness of the third target portion 33 in the first state is greater than the looseness of the third target portion 33 in the second state.

[0045] In the embodiment of the present application, the function of the first sealing member 5 is to fill the gaps between the first target portion 31 and the first fixing component 4, and between the first fixing component 4 and the first wire hole 11, so as to prevent liquid from entering the interior of the first frame body 1 through the first wire hole 11. The function of the second sealing member 7 is to fill the gaps between the second target portion 32 and the second fixing component 6, and between the second fixing component 6 and the second wire hole 21, so as to prevent liquid from entering the interior of the second frame body 2 through the second wire hole 21.

[0046] In the embodiment of the present application, the third target portion 33 is provided in correspondence with the rotating assembly. The target coating on the third target portion 33 serves to enhance the water resistance of the third target portion 33. Thus, if liquid infiltrates the rotating assembly, the target coating prevents the liquid from entering the flexible circuit board 3, protecting the electronic components on the flexible circuit board 3 from water damage and extending the service life of the electronic device. Furthermore, the target coating can be made of a variety of materials. For example, the target coating can be a nano-waterproof coating or a cellulose nanofiber coating, which is not limited in the embodiment of the present application.

[0047] In the embodiment of the present application, the third target portion 33 is provided corresponding to the rotating assembly. When the electronic device switches to a state, the distance between the first wire hole 11 on the first frame 1 and the second wire hole 21 on the second frame 2 will change. Driven by the first frame 1 and the second frame 2, the third target portion 33 will also change state accordingly. When the electronic device switches to a folded state, the distance between the first wire hole 11 on the first frame 1 and the second wire hole 21 on the second frame 2 is smaller, so that the pulling force of the first frame 1 and the second frame 2 on the third target portion 33 is smaller. At this time, the third target portion 33 is in the first state, and the slackness of the third target portion 33 is larger; refer to Figure 1 When the electronic device is switched to the unfolded state, the distance between the first wire hole 11 on the first frame body 1 and the second wire hole 21 on the second frame body 2 is large, so that the pulling force of the first frame body 1 and the second frame body 2 on the third target part 33 is large. At this time, the third target part 33 is in the second state, and the slackness of the third target part 33 is small.

[0048] In the technical solution provided in the present application, the second fixing component 6 is located in the second wire-passing hole 21 to fix the second target portion 32 on the flexible circuit board 3 located in the second wire-passing hole 21. The second sealing member 7 is located in the second wire-passing hole 21 to fill the gaps between the second target portion 32 and the second fixing component 6, and between the second fixing component 6 and the second wire-passing hole 21. When assembling an electronic device, the second end of the flexible circuit board 3 can be passed through the second wire-passing hole 21 first; then the second fixing component 6 is installed in the second wire-passing hole 21 to fix the second target portion 32 in the second wire-passing hole 21; and finally, the second sealing member 7 is installed in the second wire-passing hole 21 to fill the gaps between the second target portion 32 and the second fixing component 6, and between the second fixing component 6 and the second wire-passing hole 21. Here, the second target part 32 is fixed by the second sealing assembly, and when the electronic device switches states, the second target part 32 can be prevented from swinging in the second wire-passing hole 21, thereby avoiding wear of the second seal 7 in the second wire-passing hole 21 and extending the service life of the second seal 7; the second seal 7 is installed in the second wire-passing hole 21. On the one hand, the second wire-passing hole 21 can provide a larger accommodating space for the second seal 7, so that the second seal 7 can form a thicker sealing surface in the extension direction of the second wire-passing hole 21, thereby improving the sealing effect of the second seal 7; on the other hand, the second seal 7 can contact the inner wall of the second wire-passing hole 21 in the second wire-passing hole 21, so that the second seal 7 can have a sufficient attachment area, reducing the probability of the second seal 7 slipping out of the second wire-passing hole 21, and improving the reliability of the second seal 7 when in use.

[0049] In the embodiment of the present application, the function of the second fixing component 6 is to fix the second target part 32 on the flexible circuit board 3 located in the second wire hole 21. Therefore, the second fixing component 6 can adopt the same structural design as the first fixing component 4, or a different structural design. The embodiment of the present application does not limit the structural form of the second fixing component 6.

[0050] In the embodiment of the present application, the function of the second seal 7 is to fill the gap between the second target part 32 and the second fixing component 6, and the gap between the second fixing component 6 and the second wire hole 21. Therefore, the second seal 7 can adopt the same structural form as the first seal 5, or a different structural form. The embodiment of the present application does not limit the structural form of the second seal 7.

[0051] The above are only preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
