The flip module consists of a fixed part and a rotating part, which are connected by a hinge. The camera on the rotating part needs to connect to the motherboard. Currently, this is mainly achieved by setting an adapter board on the rotating part, connecting the camera to the adapter board, and then connecting the adapter board to the motherboard via a wiring harness. However, during the flipping process, the wiring harness rubs against the hinge, which can easily cause wear and tear. At the same time, to avoid the wiring harness, a significant portion of the hinge needs to be removed, resulting in lower hinge strength, easy deformation, and affecting the reliability of the flip structure.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] In the description of the embodiments of this utility model, it should be noted that, unless otherwise expressly specified and limited, the terms "first" and "second" are numbered for the purpose of clearly identifying product components and do not represent any substantial difference. The terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances. Furthermore, "multiple" means two or more. In the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0031] The following is combined with Figures 1-4 This invention describes the flip module and electronic device.

[0032] like Figure 1 and Figure 2 As shown, the flip module provided in this embodiment of the present invention includes a first housing 1, a second housing 2, a functional module 3, and a first flexible circuit board 4. The second housing 2 is provided with a rotating shaft 21, which is rotatably connected to the first housing 1. The functional module 3 is disposed in the second housing 2. The first flexible circuit board 4 includes a first connecting portion 41 and a second connecting portion 42 connected together. The first connecting portion 41 is fixed relative to the rotating shaft 21 and electrically connected to the functional module 3. A portion of the second connecting portion 42 is wound around the rotating shaft 21 circumferentially, and can be tightened and loosened relative to the rotating shaft 21 as the rotating shaft 21 rotates. The second connecting portion 42 is used for electrical connection with an external circuit board.

[0033] Specifically, the first housing 1 is provided with a shaft hole 11, and the rotating shaft 21 of the second housing 2 is rotatably engaged with the shaft hole 11 of the first housing 1 to realize the rotatable connection between the first housing 1 and the second housing 2. Specifically, rotating shafts 21 are respectively protruding on opposite sides of the second housing 2, and the first housing 1 is provided with two corresponding shaft holes 11. The two rotating shafts 21 on the second housing 2 are rotatably disposed in the two shaft holes 11 on the first housing 1. Among them, the rotating shaft 21 of the second housing 2 is partially inserted into the shaft hole 11 of the second housing 2, and the part of the rotating shaft 21 outside the shaft hole 11 is connected to the first connecting part 41 of the first flexible circuit board 4.

[0034] When the second housing 2 rotates relative to the first housing 1, it drives the functional module 3 to rotate relative to the first housing 1. The first connecting portion 41 of the first flexible circuit board 4 is fixed relative to the rotating shaft 21, meaning that the first connecting portion 41 can rotate synchronously with the rotating shaft 21. A portion of the second connecting portion 42 near the first connecting portion 41 is circumferentially wrapped around the rotating shaft 21 and can tighten and loosen relative to the rotating shaft 21 as the rotating shaft 21 rotates. The end of the second connecting portion 42 away from the first connecting portion 41 is used for electrical connection with an external circuit board. In this way, it can be ensured that one end of the first flexible circuit board 4 is fixed relative to the functional module 3, the other end is fixed relative to the external circuit board, and the middle section provides sufficient room for rotation of the second housing 2 relative to the first housing 1, realizing the electrical connection between the functional module 3 and the external circuit board.

[0035] The second housing 2 is rotatable relative to the first housing 1 between a first angular position and a second angular position. When the second housing 2 is in the first angular position relative to the first housing 1, the second connecting portion 42 is tightened relative to the rotating shaft 21. When the second housing 2 is in the second angular position relative to the first housing 1, the second connecting portion 42 is loosened relative to the rotating shaft 21. The second housing 2 rotates relative to the first housing 1 between the first angular position and the second angular position, that is, the second connecting portion 42 switches between a tightened state and a loosened state relative to the rotating shaft 21.

[0036] The first housing 1 can be used to fix it to the main body of the electronic device, or the first housing 1 itself can be part of the housing of the electronic device. The functional module 3 can be a camera module to form a flip camera module, and the camera angle can be adjusted by adjusting the angle of the second housing 2 relative to the first housing 1. The functional module 3 can also be other types of functional modules 3, such as a display module, to form a flip display module, and the display angle can be adjusted by adjusting the angle of the second housing 2 relative to the first housing 1.

[0037] The flip module provided in this embodiment of the utility model, by setting a first flexible circuit board 4 with a first connecting part 41 and a second connecting part 42, the first connecting part 41 is fixed relative to the rotating shaft 21, and the first connecting part 41 connects to the functional module 3 and the second connecting part 42 connects to the external circuit board, realizing the electrical connection between the functional module 3 on the flip module and the external circuit board. By setting a part of the second connecting part 42 to be wound around the rotating shaft 21 along the axial direction of the rotating shaft 21, and being able to tighten and loosen relative to the rotating shaft 21 as the rotating shaft 21 rotates, frictional damage to the first flexible circuit board 4 caused by the rotating shaft 21 during rotation can be avoided; at the same time, the first flexible circuit board 4 is a sheet structure, which can reduce the amount of material that the rotating shaft 21 needs to cut to avoid the first flexible circuit board 4, improve the structural strength of the rotating shaft 21, avoid deformation of the rotating shaft 21, and improve the reliability of the flip structure.

[0038] like Figure 1 As shown, the flip module provided in this embodiment of the present invention also includes a second flexible circuit board, and a first connector 43 is provided on the first connecting part 41. One end of the second flexible circuit board is electrically connected to the functional module 3, and the other end is connected to the first connector 43. The first connector 43 on the first connecting part 41 is an FPC first connector 43, and the first flexible circuit board 4 is electrically connected to the second flexible circuit board through the FPC first connector 43. Compared with the traditional wire harness connection method, this embodiment eliminates the need for an adapter board, saving module costs and simplifying the module assembly process.

[0039] In some embodiments of this invention, when the second housing 2 is in the first angular position, the second connecting portion 42 is loosened relative to the rotating shaft 21. When the second housing 2 is in the second angular position, the second connecting portion 42 is tightened relative to the rotating shaft 21, and the circumferential angle around the rotating shaft 21 is 180°~270°.

[0040] Taking a flip-up module with a flip-up camera mounted on a learning machine as an example, the first housing 1 is fixed to the top of the main body of the learning machine. When the second housing 2 is in the first angle position, the second housing 2 is located on the back of the main body, the camera faces the back of the main body, and the second connecting part 42 is loosened relative to the rotating shaft 21. When the second housing 2 is in the second angle position, the second housing 2 flips to the top of the main body, the camera faces the front of the main body, and the second connecting part 42 is tightened relative to the rotating shaft 21.

[0041] It should be noted that, in some optional embodiments, the second connecting part 42 may be tightened relative to the rotating shaft 21 when the second housing 2 is in the first angular position, and the second connecting part 42 may be loosened relative to the rotating shaft 21 when the second housing 2 is in the second angular position.

[0042] When the second connecting portion 42 is tightened relative to the rotating shaft 21, the circumferential angle of the second connecting portion 42 around the rotating shaft 21 is 180° to 270°. It can be understood that when the second housing 2 is in the first angular position, the circumferential angle of the second connecting portion 42 around the rotating shaft 21 can be any number between 180° and 270°. Correspondingly, the maximum degree of rotation of the second housing 2 relative to the first housing 1 is any number between 180° and 270°, such as 180°, 210°, 250°, or 270°.

[0043] Furthermore, a damping element is provided between the second housing 2 and the first housing 1, so that the second housing 2 can be suspended at any angle position between the first angle position and the second angle position, thus meeting the needs of multi-angle shooting.

[0044] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the first connecting part 41 includes a first fixing part 411 and a second fixing part 412 connected together. The first fixing part 411 is fixed to the second housing 2 and electrically connected to the functional module 3. The rotating shaft 21 is provided with a slot 12 extending along the axial direction of the rotating shaft 21, the second fixing part 412 is inserted into the slot 12, and the second connecting part 42 is connected to the second fixing part 412.

[0045] Understandably, the first fixing part 411 of the functional module 3 is fixed to the second housing 2, and the second fixing part 412 is inserted into the rotating shaft 21. When the rotating shaft 21 rotates, the second housing 2 drives the functional module 3, the first fixing part 411 and the second fixing part 412 to rotate synchronously, and the second fixing part 412 drives the second connecting part 42 to tighten or loosen relative to the rotating shaft 21.

[0046] Optionally, the first connecting portion 41 and the second connecting portion 42 are connected in an "L" shape, with the length direction of the first connecting portion 41 and the length direction of the second connecting portion 42 perpendicular to each other. Specifically, the first fixing portion 411 and the second fixing portion 412 are arranged along the length direction of the first connecting portion 41, and the second connecting portion 42 is connected to the second fixing portion 412 on one side of the length direction of the first connecting portion 41. The end of the second connecting portion 42 away from the second fixing portion 412 is used for electrical connection with an external circuit board.

[0047] It should be noted that, if the diameter of the rotating shaft 21 is large enough and the relevant structural space allows, the second fixing part 412 can be attached and fixed to the side surface of the rotating shaft 21. In this way, the rotating shaft 21 does not need to be provided with the slot 12, which can avoid cutting off the rotating shaft 21 and also avoid bending damage to the part of the flexible circuit board corresponding to the slot 12 slot opening.

[0048] Optionally, the first fixing part 411 is bonded to the second housing 2 by an adhesive. Optionally, a portion of the second connecting part 42 is bonded to the first housing 1 by an adhesive.

[0049] like Figure 2 and Figure 4 As shown, the flipping module provided in this embodiment of the present invention also includes a flexible plug 5. The flexible plug 5 is inserted into the slot 12 and pressed between the second fixing part 412 and the slot wall of the slot 12. A bend 44 is formed at the position where the second fixing part 412 and the second connecting part 42 are connected. A portion of the flexible plug 5 is located outside the slot 12 and inside the bend 44. The inside of the bend 44 corresponds to one side of the bending direction of the bend 44, i.e., the inside of the bend angle. Optionally, the flexible plug 5 is a flexible body with a certain elasticity, such as a silicone plug or a TPE soft plug.

[0050] The second fixing part 412 is pressed between the flexible plug 5 and the groove wall of the slot 12, serving to fix the flexible circuit board. At the same time, a part of the flexible plug 5 is located outside the slot 12 and inside the bending part 44, that is, a part of the flexible plug 5 protrudes from the side wall of the rotating shaft 21 and is located inside the bend angle of the bending part 44. When the second connecting part 42 is tightened, the bending part 44 and the flexible plug 5 are in elastic contact, which can prevent the flexible circuit board from breaking when it is subjected to flipping force and effectively buffer the flexible circuit board, thereby avoiding bending damage to the flexible circuit board.

[0051] Furthermore, the flexible plug 5 has an arc-shaped surface 51 on the side facing the bent portion 44. When the second connecting portion 42 is tightened, the bent portion 44 fits against the arc-shaped surface 51. Under the support of the arc-shaped surface 51, the bent portion 44 is prevented from forming a small fold angle, ensuring that the flexible circuit board is not bent and damaged.

[0052] like Figure 3 As shown, in some embodiments of this utility model, the second housing 2 is provided with a mounting surface 13, one wall of the slot 12 is coplanar with the mounting surface 13, the first fixing part 411 is mounted on the mounting surface 13, and the second fixing part 412 is fitted against the slot wall. It can be understood that a portion of the first connecting part 41 is inserted into the slot 12, and another portion extends from the slot 12 to the mounting surface 13 and is fixed thereto. Setting the slot wall of the slot 12 coplanar with the mounting surface 13 facilitates the installation of the first connecting part 41 and also facilitates the manufacturing of the second housing 2.

[0053] The second fixing part 412 can be fixed to the wall of the slot 12, and the first fixing part 411 can be fixed to the mounting surface 13, both by adhesives. When a flexible plug 5 is provided in the slot 12, the second fixing part 412 does not need to be fixed to the slot wall by other fasteners, which facilitates maintenance and disassembly.

[0054] Furthermore, the mounting surface 13 is provided with a positioning groove 131, and the first fixing part 411 is disposed in the positioning groove 131. Specifically, the positioning groove 131 is a groove recessed in the mounting surface 13, which can provide quick positioning for the installation of the first fixing part 411, which is beneficial for the quick installation of the flexible circuit board.

[0055] In some embodiments of this invention, when the second housing 2 is in the first angular position, the second housing 2 is unfolded relative to the first housing 1. When the second housing 2 is in the second angular position, the second housing 2 is folded relative to the first housing 1. This facilitates the installation of the first flexible circuit board 4. When installing the first flexible circuit board 4, the second housing 2 is unfolded relative to the first housing 1 to the first angular position. First, the second fixing part 412 is inserted into the slot 12. Then, the first fixing part 411 is fixed to the second housing 2, and the second connecting part 42 is wound around the rotating shaft 21, with the winding degree aimed at giving the second housing 2 sufficient rotational movement.

[0056] like Figure 1 As shown, in some embodiments of this utility model, rotating shafts 21 are respectively provided on the opposite sides of the second housing 2, and there are two functional modules 3 and two first flexible circuit boards 4. The two first flexible circuit boards 4 are arranged in a one-to-one correspondence with the two rotating shafts 21, and the two functional modules 3 are electrically connected to the two first flexible circuit boards 4 in a one-to-one correspondence.

[0057] In some embodiments of this utility model, the first housing 1 is provided with a through hole, the second connecting part 42 passes through the through hole, the end of the second connecting part 42 away from the first connecting part 41 is located outside the first housing 1 and is provided with a second connector, and the flexible circuit board is electrically connected to the external circuit board through the second connector.

[0058] Optionally, such as Figure 1 As shown, the flipping module provided in this embodiment of the present invention also includes a cover 6, which is disposed on the second housing 2, and the functional module 3 is housed in the accommodating space formed by the second housing 2 and the cover 6.

[0059] This utility model embodiment also provides an electronic device, which is not limited to devices requiring a folding module such as learning machines, game consoles, mobile phones, or laptops. The electronic device includes a main body and a folding module as described in any of the above embodiments, with a first housing 1 fixedly connected to the main body.

[0060] The main body includes a motherboard, and a second connector is provided at the end of the second connecting part 42 away from the first connecting part 41. The second connector is electrically connected to the motherboard. The second connector can be a BTB connector.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
