Technical Field

[0001] The present application belongs to the technical field of electronic products, and specifically relates to an electronic device. Background Art

[0002] With the progress and development of electronic devices, foldable electronic devices have become the current development trend of electronic devices. Foldable electronic devices generally include a first body, a second body and a hinge mechanism, and the hinge mechanism rotates to connect the first body and the second body so that the electronic device has a folding function and an unfolding function. In order to achieve signal transmission between the first body and the second body, a signal transmission line is provided between the first body and the second body, and the signal transmission line connects the circuit boards on the first body and the second body to achieve signal communication between the first body and the second body.

[0003] When the signal transmission line is installed, the signal transmission line needs to pass through the first body, the hinge mechanism and the second body in sequence, which requires that the outer sides of the first body and the second body be provided with break-through areas, that is, the signal transmission line needs to pass through the break-through area of ​​the first body, the hinge mechanism and the break-through area of ​​the second body in sequence, so as to achieve the installation of the signal transmission line.

[0004] However, since a penetration area is provided on the outer side of the first body and the second body, in order to prevent water from entering the interior of the electronic device through the penetration area and causing adverse effects on the battery and circuit board of the electronic device, it is necessary to provide a waterproof pressure plate in the penetration area, that is, it is necessary to add a waterproof structure to the first body and the second body, which makes the overall structure of the electronic device more complicated.

[0005] In summary, the electronic equipment involved in the related art has the problem of relatively complex structure. Summary of the invention

[0006] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem that the electronic devices involved in the related art have a relatively complex structure.

[0007] An embodiment of the present application provides an electronic device, including a first body, a second body and a signal transmission line, wherein a first circuit board is provided in the first body, a second circuit board is provided in the second body, the signal transmission line is used to electrically connect the first circuit board and the second circuit board, and at least a portion of the signal transmission line is provided between a flexible display screen of the electronic device and the first body and the second body.

[0008] In the embodiment of the present application, since at least part of the signal transmission line is arranged between the flexible display screen and the first body and the second body of the electronic device, that is, at least part of the signal transmission line in the present application is arranged close to the flexible display screen and away from the outer sides of the first body and the second body, that is, the signal transmission line does not need to pass through the outer sides of the first body and the second body. Therefore, the present application does not need to set a breaking area on the outer sides of the first body and the second body, and thus does not need to add a waterproof structure on the first body and the second body, which can simplify the structure of the electronic device to a certain extent.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0024] The electronic device disclosed in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0025] Please refer to Figure 1-Figure 4 The present application discloses an electronic device, which includes a first body 100 , a second body 200 and a signal transmission line 300 .

[0026] The first body 100 and the second body 200 are two main components of the electronic device. The signal transmission line 300 is used to achieve signal communication between the first body 100 and the second body 200. Specifically, a first circuit board 110 is provided in the first body 100, and a second circuit board 210 is provided in the second body 200. One of the first circuit board 110 and the second circuit board 210 can be a main board, and the other can be a sub-board. The signal transmission line 300 is used to electrically connect the first circuit board 110 and the second circuit board 210 to achieve the purpose of signal communication between the first body 100 and the second body 200.

[0027] The flexible display screen 400 of the electronic device is used to realize the display function of the electronic device. The flexible display screen 400 is arranged between the first body 100 and the second body 200, and at least a part of the signal transmission line 300 is arranged between the flexible display screen 400 and the first body 100 and the second body 200, that is, at least a part of the signal transmission line 300 is arranged in the space formed between the flexible display screen 400 and the first body 100 and the second body 200. In other words, a space for accommodating the signal transmission line 300 is formed between the flexible display screen 400 and the first body 100 and between the flexible display screen 400 and the second body 200, so that the flexible display screen 400, the first body 100 and the second body 200 can jointly restrict and protect the signal transmission line 300.

[0028] Optionally, the signal transmission line 300 may be in the form of a FPC (Flexible Printed Circuit), an MPI (Multipoint Interface), a coaxial line, an LDS (Laser Directstructuring) line, a silk-screen line, or the like.

[0029] In the embodiment of the present application, since at least a portion of the signal transmission line 300 is disposed between the flexible display screen 400 and the first body 100 and the second body 200 of the electronic device, that is, at least a portion of the signal transmission line 300 in the present application is disposed close to the flexible display screen 400, and is disposed away from the outer sides of the first body 100 and the second body 200, that is, the signal transmission line 300 does not need to pass through the outer sides of the first body 100 and the second body 200. Therefore, the present application does not need to set a breaking area on the outer sides of the first body 100 and the second body 200, and thus does not need to add a waterproof structure to the first body 100 and the second body 200, which can simplify the structure of the electronic device to a certain extent.

[0030] At the same time, since the present application does not need to set a penetration area on the outer sides of the first body 100 and the second body 200, this can improve the waterproof performance of the entire electronic device to a certain extent.

[0031] Optionally, to ensure the stability of the electrical connection between the signal transmission line 300 and the first circuit board 110 and the second circuit board 210, the electronic device also includes a first connector 810 and a second connector 820, one end of the signal transmission line 300 is electrically connected to the first circuit board 110 through the first connector 810, and the other end of the signal transmission line 300 is electrically connected to the second circuit board 210 through the second connector 820, and the first connector 810 and the second connector 820 can realize the transmission and interaction of electrical signals or optical signals between the first circuit board 110 and the second circuit board 210.

[0032] In one embodiment, the electronic device further includes a hinge mechanism 500, which rotatably connects the first body 100 and the second body 200, that is, the hinge mechanism 500 can make at least a portion of the first body 100 and at least a portion of the second body 200 approach each other or move away from each other, so as to realize the folding function or the unfolding function of the electronic device, and at least a portion of the signal transmission line 300 can be arranged through the hinge mechanism 500, that is, at least a portion of the signal transmission line 300 can be arranged inside the hinge mechanism 500.

[0033] In another embodiment, at least part of the signal transmission line 300 is arranged between the flexible display screen 400 and the hinge mechanism 500, that is, at least part of the signal transmission line 300 does not pass through the interior of the hinge mechanism 500, so that the signal transmission line 300 does not affect the design of the hinge mechanism 500, that is, the design of the hinge mechanism 500 is freer and more reliable, and is no longer limited by the arrangement of the signal transmission line 300, which is more conducive to the thin and light design of the hinge mechanism 500, the hovering experience design and the miniaturization design of the electronic device. At the same time, since the signal transmission line 300 neither passes through the outside of the first body 100 and the second body 200, nor passes through the interior of the hinge mechanism 500, this simplifies the manufacturing process to a certain extent and improves the production yield of the electronic device.

[0034] Specifically, the hinge mechanism 500 may include a base 510, a floating plate 520, a first supporting plate 530 and a second supporting plate 540. The base 510 is rotatably connected to the first body 100 and the second body 200. The floating plate 520 is movably arranged on a side of the base 510 facing the flexible display screen 400 to support the flexible display screen 400, that is, the floating plate 520 is arranged opposite to the flexible display screen 400. When the first body 100 and the second body 200 are close to each other, that is, during the process of the electronic device switching from the unfolded state to the folded state, the floating plate 520 gradually moves away from the flexible display screen 400 to avoid affecting the normal folding of the flexible display screen 400. When the first body 100 and the second body 200 are far away from each other, that is, during the process of the electronic device switching from the folded state to the unfolded state, the floating plate 520 gradually moves towards the flexible display screen 400 to support the flexible display screen 400, thereby preventing the portion of the flexible display screen 400 that is arranged opposite to the floating plate 520 from being sunken, thereby avoiding affecting the display effect of the electronic device. Optionally, the floating plate 520 may be movably disposed on the base 510 via components such as springs.

[0035] The first support plate 530 and the second support plate 540 are used to support the flexible display screen 400 and the folding area (i.e., the folding area 600 of the electronic device described later) for jointly forming the water drop-shaped flexible display screen 400. The first support plate 530 is movably disposed between the base 510 and the first body 100, and the second support plate 540 is movably disposed between the base 510 and the second body 200. Specifically, one end of the first support plate 530 is rotatably disposed on the base 510, the other end of the first support plate 530 is rotatably disposed on the first body 100, and one end of the second support plate 540 is rotatably disposed on the base. 510, the other end of the second support plate 540 is rotatably disposed on the second body 200, and when the electronic device switches from the unfolded state to the folded state, the first support plate 530 and the second support plate 540 rotate relative to the base 510, so that the folded area of ​​the flexible display screen 400 presents a water drop shape, and when the electronic device switches from the folded state to the unfolded state, the first support plate 530 and the second support plate 540 rotate relative to the base 510, so that the floating plate 520, the first support plate 530 and the second support plate 540 jointly support the flexible display screen 400, thereby improving the supporting effect of the flexible display screen 400.

[0036] At least part of the signal transmission line 300 is arranged between the flexible display screen 400 and the first support plate 530, the floating plate 520 and the second support plate 540, that is, the signal transmission line 300 does not pass through the first support plate 530, the floating plate 520 and the second support plate 540 of the hinge mechanism 500. In other words, space for accommodating the signal transmission line 300 is formed between the flexible display screen 400 and the first floating plate 520, between the flexible display screen 400 and the first support plate 530, and between the flexible display screen 400 and the second support plate 540, so that there is no need to reserve installation space for the signal transmission line 300 on the hinge mechanism 500, and so the first support plate 530, the floating plate 520 and the second support plate 540 can be arranged more compactly on the hinge mechanism 500.

[0037] In one embodiment, the signal transmission line 300 may include at least two stacked and connected functional layers 310, that is, when processing and manufacturing the signal transmission line 300, the at least two functional layers 310 are integrally arranged, and the at least two functional layers 310 are used to electrically connect the first circuit board 110 and the second circuit board 210. The at least two functional layers 310 can be used to respectively realize power supply, charging, control of the flexible display screen 400, and signal transmission of the speaker, etc. For example, the second circuit board 210 can be electrically connected to the charging port of the electronic device, and the second circuit board 210 can supply power to the first circuit board 110 through one of the multiple functional layers 310.

[0038] In another embodiment, the signal transmission line 300 may include at least two stacked functional layers 310, that is, when processing and manufacturing the signal transmission line 300, the at least two functional layers 310 are separately arranged, that is, there may be no connection relationship between the multiple functional layers 310, and there is no pulling force between the functional layers 310, and the at least two functional layers 310 are used to electrically connect the first circuit board 110 and the second circuit board 210. Compared with the method of setting the multiple functional layers 310 as one body, this method of setting the multiple functional layers 310 separately can reduce the hardness of the signal transmission line 300, and then in the process of switching the electronic device from the unfolded state to the folded state, that is, in the process of the flexible display screen 400 being folded, the signal transmission line 300 is more likely to fold with the electronic device, and because the hardness of the signal transmission line 300 is relatively small, the signal transmission line 300 will not be broken due to the tensile stress during folding, that is, the folding part of the signal transmission line 300 is less likely to break, so as to ensure the folding life of the signal transmission line 300. Optionally, adjacent functional layers 310 may be in contact with each other, or adjacent functional layers 310 may be spaced apart, and in this case, adjacent functional layers 310 may be separated by a medium such as air.

[0039] In other embodiments, the signal transmission line 300 may include at least two stacked functional layers 310, each of which is used to electrically connect the first circuit board 110 and the second circuit board 210, and the portions of the at least two functional layers 310 located in the folding area 600 of the electronic device are separately arranged, and the folding area 600 is an area in the flexible display screen 400 that is in a deformed state when the electronic device is in a folded state.

[0040] It can be seen that in this embodiment, only the multiple functional layers 310 of the signal transmission line 300 at the folding part that folds with the electronic device are separately set, and the multiple functional layers 310 located outside the above-mentioned folding area 600 are set as one piece. Therefore, when separating the multiple functional layers 310 of the signal transmission line 300, the operator only needs to separate the multiple functional layers 310 located in the folding area 600 of the electronic device, and does not separate the multiple functional layers 310 located outside the folding area 600 of the electronic device. This can reduce the workload of the operator to a certain extent, thereby reducing the production cost. At the same time, since the part of the multiple functional layers 310 located in the folding area 600 is separately set, the hardness of this part is relatively small, and thus the part is easier to fold with the electronic device. In addition, when the multiple functional layers 310 outside the folding area 600 are set as one piece, the structural integrity of the signal transmission line 300 is better and easier to assemble.

[0041] Optionally, the signal transmission line 300 may include at least two stacked functional layers 310, and the at least two functional layers 310 are used to electrically connect the first circuit board 110 and the second circuit board 210. The functional layer 310 includes a layered portion 311. The layered portions 311 of the at least two functional layers 310 are separately arranged, and the layered portions 311 can be just located within the folding area 600, that is, the layered portion 311 can be the folding part of the signal transmission line 300. Since the layered portions 311 are separately arranged, the hardness of the folding part is smaller, and thus the folding part is more likely to deform with the electronic device, and the folding part is less likely to break.

[0042] In another embodiment, when the electronic device is folded, the signal transmission line 300 is easily deformed in addition to the folding part, and the part of the signal transmission line 300 close to the folding area 600 is also easily deformed. Although the tensile stress of this part is small, this part still has the risk of breaking. Therefore, a part of the above-mentioned layered part 311 can be located in the folding area 600 of the electronic device, and the other part is located outside the folding area 600, that is, the layered parts 311 of the multiple functional layers 310 located in the folding area 600 and close to the folding area 600 are evenly arranged. On the one hand, it can ensure that the multiple functional layers 310 located in the folding area 600 are easy to fold with the electronic device and are not easy to break. On the other hand, it can ensure that the multiple functional layers 310 close to the folding area 600 are easy to deform and not easy to break. It can be seen from this that the deformable range of the signal transmission line 300 can be enlarged by this setting method, and then the signal transmission line 300 is less likely to break and is easier to fold with the electronic device. It should be noted that the signal transmission line 300 except the layered part 311 can be arranged in one piece, so as to facilitate assembly.

[0043] Optionally, at least a portion of the signal transmission line 300 may be disposed on a support member 700 supporting the flexible display screen 400, that is, the support member 700 is used to support the flexible display screen 400 and can serve as a base for the signal transmission line 300 so that the signal transmission line 300 can be stably disposed in the electronic device. Optionally, at least a portion of the signal transmission line 300 is detachably in contact with the support member 700, that is, the two are only in contact but not directly connected.

[0044] In order to prevent the signal transmission line 300 from shaking when the electronic device shakes, thereby affecting the stability of the electrical connection between the signal transmission line 300 and the first circuit board 110 and the second circuit board 210, and further affecting the effect of signal transmission of the signal transmission line 300, in another embodiment, at least a portion of the signal transmission line 300 is bonded and connected to the support member 700, and this setting method is used to fix the position of the signal transmission line 300 in the electronic device to prevent the signal transmission line 300 from shaking when the electronic device shakes. Optionally, at least a portion of the signal transmission line 300 can be bonded and connected to the support member 700 by glue, and the area where the signal transmission line 300 and the support member 700 are bonded can be far away from the folding area 600 of the electronic device, that is, the area where the signal transmission line 300 is less deformed or even not deformed.

[0045] In a further embodiment, at least a portion of the signal transmission line 300 is disposed on a support member 700 supporting the flexible display screen 400, that is, the support member 700 is used to support the flexible display screen 400 while serving as an installation base for the signal transmission line 300, and at least a portion of the signal transmission line 300 is in contact with the support member 700, that is, a contact area between the signal transmission line 300 and the support member 700 is larger, so that the support member 700 can constrain the signal transmission line 300, which makes the signal transmission line 300 more stably arranged in the electronic device, and the signal transmission line 300 and the support member 700 as a whole occupy less space in the electronic device.

[0046] In this embodiment, when the signal transmission line 300 is specifically installed, the signal transmission line 300 can be first fitted with the support member 700, and then the first body 100 and the second body 200 can be installed, and finally the assembly of other parts of the electronic device can be completed. Alternatively, the signal transmission line 300 can be first installed on the first body 100 and the second body 200, and then the support member 700 and the flexible display screen 400 can be simultaneously installed on the first body 100 and the second body 200 to fit the support member 700 with the signal transmission line 300, and finally the assembly of other parts of the electronic device can be completed, thereby realizing the assembly of the electronic device. Compared with the conventional installation method of passing the signal transmission line 300 through the outside of the first body 100 and the second body 200, this installation method effectively simplifies the assembly process to a certain extent.

[0047] Optionally, the first body 100 includes a first middle frame 120, the second body 200 includes a second middle frame 220, and the hinge mechanism 500 of the electronic device (i.e., the hinge mechanism 500 described above) connects the first middle frame 120 and the second middle frame 220 by rotation to achieve rotational connection between the first body 100 and the second body 200, the first circuit board 110 and the first middle frame 120 may be in contact, and the second circuit board 210 and the second middle frame 220 may be in contact; or, the first circuit board 110 and the first middle frame 120 are spaced apart, that is, there is a first gap between the first circuit board 110 and the first middle frame 120, and the second circuit board 210 and the second middle frame 220 are spaced apart, that is, there is a second gap between the second circuit board 210 and the second middle frame 220.

[0048] The first part 320 of the signal transmission line 300 is arranged between the first circuit board 110 and the first middle frame 120, that is, the first part 320 is arranged in the first gap, and the first part 320 is limited by the first circuit board 110 and the first middle frame 120. The second part 330 of the signal transmission line 300 is arranged between the second circuit board 210 and the second middle frame 220, that is, the second part 330 is arranged in the second gap, and the second part 330 is limited by the second circuit board 210 and the second middle frame 220. The third part 340 of the signal transmission line 300 is arranged between the flexible display screen 400 and the first middle frame 120. The fourth part 350 of the signal transmission line 300 is arranged between the flexible display screen 400 and the second middle frame 220, that is, the third part 340 and the fourth part 350 are limited by the flexible display screen 400 and the first middle frame 120 and the second middle frame 220. It can be seen from this that please refer to Figure 1 The shape of the signal transmission line 300 is bent, and because the signal transmission line 300 is limited at multiple locations in the electronic device, the signal transmission line 300 can be more stably arranged in the electronic device.

[0049] Optionally, the third portion 340 may be spaced apart from the first middle frame 120 , and the fourth portion 350 may be spaced apart from the second middle frame 220 .

[0050] In another embodiment, the third part 340 is arranged between the flexible display screen 400 and the first middle frame 120, and the third part 340 is bonded to the first middle frame 120. This arrangement fixes the position of the signal transmission line 300 to prevent the signal transmission line 300 from shaking inside the electronic device, thereby avoiding affecting the electrical connection stability between the signal transmission line 300 and the first circuit board 110 and the second circuit board 210.

[0051] Similarly, to ensure the installation stability of the signal transmission line 300 in the electronic device, the fourth part 350 is arranged between the flexible display screen 400 and the second middle frame 220, and the fourth part 350 is bonded to the second middle frame 220, that is, the position of the signal transmission line 300 is fixed by this arrangement to prevent the signal transmission line 300 from shaking inside the electronic device, so as to avoid affecting the electrical connection stability between the signal transmission line 300 and the first circuit board 110 and the second circuit board 210.

[0052] Optionally, in the width direction of the electronic device (i.e., the direction of the folding axis of the electronic device), the first part 320 has a first width, the second part 330 has a second width, the third part 340 has a third width, and the fourth part 350 has a fourth width. The first width and the second width may both be greater than the third width and the fourth width, or the first width, the second width, the third width and the fourth width may all be equal, that is, the width of the signal transmission line 300 is the same at each location.

[0053] In another embodiment, the third width and the fourth width may be greater than the first width and the second width. In this case, the third width and the fourth width may be equal or unequal, and the first width and the second width may be equal or unequal. Figure 3 , the third width and the fourth width can be made equal, and the first width and the second width can be made equal. It can be seen that the signal transmission line 300 has two different widths. Since the third part 340 and the fourth part 350 are both arranged close to the folding area 600 of the electronic device, when the electronic device is folded, the third part 340 and the fourth part 350 with larger widths have greater structural strength, and thus the signal transmission line 300 is not easy to break when the electronic device is folded. That is, by making the third width and the fourth width both larger than the first width and the second width, the phenomenon that the signal transmission line 300 is more likely to break can be avoided.

[0054] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
