Description

Technical Field

[0001] The present invention relates to the field of electronic equipment, and more particularly to an electronic equipment and an assembly method thereof. Background Art

[0002] With the advancement of technology, electronic devices are increasingly being used, enabling users to capture images, watch videos, and more. Typically, electronic devices are equipped with flexible circuit boards (FPCBs), which connect two components within the electronic device to achieve signal transmission. In related art, electronic devices include a stacked plate structure with through-holes defined therein, through which FPCBs are inserted. However, FPCBs are prone to contact with the walls of the through-holes, which can easily abrade the FPCBs and damage them. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide an electronic device and an assembly method that can solve the problem that the hole wall of the through hole easily wears the flexible circuit board, causing the flexible circuit board to be easily damaged.

[0004] In a first aspect, an embodiment of the present application provides an electronic device, comprising a first plate-shaped structure, a second plate-shaped structure, a flexible circuit board, a first limiting member, and a second limiting member;

[0005] The first plate-like structure and the second plate-like structure are stacked along a first direction, the first plate-like structure is provided with a first through hole, and the second plate-like structure is provided with a second through hole;

[0006] The flexible circuit board is inserted into the first through hole and the second through hole;

[0007] The first portion of the first limiting member is disposed in the first through hole to limit movement of the flexible circuit board in the first through hole;

[0008] The second limiting member is located between the first plate-like structure and the second plate-like structure, and the second through hole has a first hole wall and a second hole wall arranged opposite to each other. The orthographic projection of the second limiting member on the second plate-like structure spans the first hole wall and extends between the first hole wall and the second hole wall to limit the movement of the flexible circuit board toward the direction close to the first hole wall.

[0009] In a second aspect, an embodiment of the present application provides an assembly method, the assembly method comprising:

[0010] Providing a first limiting member and a second limiting member, wherein the second limiting member has a connecting portion connected to the first limiting member;

[0011] Inserting the flexible circuit board into the first through hole;

[0012] Installing the first limiting member in the first through hole, and rotating the second limiting member so that an angle is formed between the second limiting member and the first limiting member;

[0013] The flexible circuit board is passed through the second through hole, the second limiting member is reset, and force is applied to the flexible circuit board so that the flexible circuit board abuts against the second limiting member.

[0014] In the embodiment of the present application, since the first plate-like structure and the second plate-like structure are stacked along the first direction, the first plate-like structure is provided with a first through hole, and the second plate-like structure is provided with a second through hole, the flexible circuit board can pass through the first through hole and the second through hole. Since the first part of the first limiting member is provided in the first through hole, the first part of the first limiting member can limit the movement of the flexible circuit board in the first through hole, which is equivalent to limiting the flexible circuit board in the first through hole. Since the second limiting member is located between the first plate-like structure and the second plate-like structure, the positive projection of the second limiting member on the second plate structure extends across the first hole wall to between the first hole wall and the second hole wall. Therefore, after the flexible circuit board abuts the second limiting member, the second limiting member can limit the flexible circuit board to prevent the flexible circuit board from moving in the direction close to the first hole wall, thereby preventing the flexible circuit board from contacting the first hole wall. That is, in the embodiment of the present application, by setting the first limit member and the second limit member, the first limit member limits the flexible circuit board in the first through hole, and the second limit member limits the contact between the flexible circuit board and the first hole wall, thereby avoiding the wear of the flexible circuit board by the first hole wall, which causes the problem of the flexible circuit board being easily damaged, thereby improving the service life of the flexible circuit board.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0028] like Figures 1 to 8 As shown, the electronic device includes a first plate-shaped structure 20 , a second plate-shaped structure 30 , a flexible circuit board 40 , a first limiting member 50 and a second limiting member 60 .

[0029] The first plate-like structure 20 and the second plate-like structure 30 are stacked along a first direction X. The first plate-like structure 20 is provided with a first through-hole 21, and the second plate-like structure 30 is provided with a second through-hole 31. The flexible circuit board 40 is inserted into the first through-hole 21 and the second through-hole 31. The first portion 501 of the first limiting member 50 is provided in the first through-hole 21 to limit the movement of the flexible circuit board 40 within the first through-hole 21. The second limiting member 60 is located between the first plate-like structure 20 and the second plate-like structure 30. The second through-hole 31 has a first hole wall 311 and a second hole wall 312 arranged opposite each other. The orthographic projection of the second limiting member 60 on the second plate-like structure 30 extends across the first hole wall 311 to between the first hole wall 311 and the second hole wall 312, thereby limiting the movement of the flexible circuit board 40 toward the first hole wall 311.

[0030] In the embodiment of the present application, since the first plate-like structure 20 and the second plate-like structure 30 are stacked along the first direction X, the first plate-like structure 20 is provided with the first through hole 21, and the second plate-like structure 30 is provided with the second through hole 31, the flexible circuit board 40 can pass through the first through hole 21 and the second through hole 31. Since the first portion 501 of the first limiting member 50 is provided in the first through hole 21, the first portion 501 of the first limiting member 50 can limit the movement of the flexible circuit board 40 in the first through hole 21, which is equivalent to limiting the flexible circuit board 40 in the first through hole 21. Because the second stopper 60 is located between the first plate-like structure 20 and the second plate-like structure 30, the orthographic projection of the second stopper 60 on the second plate-like structure 30 extends across the first hole wall 311 to between the first hole wall 311 and the second hole wall 312. Therefore, after the flexible circuit board 40 abuts the second stopper 60, the second stopper 60 can limit the flexible circuit board 40, preventing the flexible circuit board 40 from moving toward the first hole wall 311, thereby preventing the flexible circuit board 40 from contacting the first hole wall 311. That is, in the embodiment of the present application, by providing the first stopper 50 and the second stopper 60, the first stopper 50 limits the flexible circuit board 40 in the first through hole 21, and the second stopper 60 limits the flexible circuit board 40 from contacting the first hole wall 311, thereby preventing the first hole wall 311 from abrading the flexible circuit board 40, thereby preventing the flexible circuit board 40 from being easily damaged, thereby improving the service life of the flexible circuit board 40.

[0031] It should be noted that in the embodiment of the present application, the first plate-like structure 20 can be a main upper bracket in an electronic device, that is, a support plate structure such as a middle frame in an electronic device. The second plate-like structure 30 can be a sub-board in an electronic device, that is, a circuit board in an electronic device. Of course, the first plate-like structure 20 and the second plate-like structure 30 can also be other structures in an electronic device. For example, the first plate-like structure 20 is a mainboard in an electronic device, and the second plate-like structure 30 is a main upper bracket in an electronic device. This embodiment of the present application is not limited to this.

[0032] Additionally, in some embodiments, Figure 2 As shown, the first limiting member 50 and the second limiting member 60 are opposite to each other, and at least a portion of the flexible circuit board 40 is sandwiched between the first limiting member 50 and the second limiting member 60 .

[0033] Through such a setting, the first limiting member 50 and the second limiting member 60 can be limited in the first direction X, and the shape of the flexible circuit board 40 between the first limiting member 50 and the second limiting member 60 can be fixed to a preset shape, thereby preventing the flexible circuit board 40 from deforming and deviating in the first direction and causing unnecessary bending damage, thereby improving the stability and reliability of the electrical connection of the flexible circuit board 40.

[0034] It should be noted that the flexible circuit board 40 may be provided with a connector 401, which can connect the flexible circuit board 40 to other components in the electronic device via the connector 401, thereby enabling the flexible circuit board 40 to transmit signals. The connector 401 may be an electrical connection contact or an electrical connection connector, which is not specifically limited here.

[0035] Additionally, in some embodiments, Figure 2 As shown, a protrusion structure 601 is provided on the surface of the first limiting member 50 facing the second limiting member 60 or on the surface of the second limiting member 60 facing the first limiting member 50 to further limit the movement of the flexible circuit board 40 along the first direction X.

[0036] Through such a setting, the protruding structure 601 can further limit the flexible circuit board 40, further reduce the movable range of the flexible circuit board 40 along the first direction X, thereby reducing the deformation offset of the flexible circuit board 40 in the first direction, so that the shape of the flexible circuit board 40 between the first limiting member 50 and the second limiting member 60 is fixed, thereby preventing the flexible circuit board from causing unnecessary bending damage due to movement in the first direction, and improving the stability and reliability of the electrical connection of the flexible circuit board 40.

[0037] It should be noted that the raised structure 601 can abut against the flexible circuit board 40, thereby clamping the flexible circuit board 40 between the first and second stoppers 50, 60, preventing the flexible circuit board 40 from deforming and deflecting in the first direction, further improving the stability and reliability of the electrical connection of the flexible circuit board 40. Specifically, when the raised structure 601 is provided on the surface of the first stopper 50 facing the second stopper 60, the two opposing surfaces of the flexible circuit board 40 abut against the raised structure 601 and the second stopper 60, respectively. When the raised structure 601 is provided on the surface of the second stopper 60 facing the first stopper 50, the two opposing surfaces of the flexible circuit board 40 abut against the raised structure 601 and the first stopper 50, respectively.

[0038] In addition, in the embodiment of the present application, a relief groove (not shown) may be provided on the protruding structure 601. The flexible circuit board 40 located between the first stopper 50 and the second stopper 60 is positioned within the relief groove. Thus, the relief groove restrains the flexible circuit board 40 in a plane perpendicular to the first direction X. This not only allows the flexible circuit board 40 to be clamped and restrained in the first direction X by the first stopper 50 and the second stopper 60, but also prevents the flexible circuit board 40 from moving and deforming in the gap between the first stopper 50 and the second stopper 60 in a direction perpendicular to the first direction X. This further maintains the shape of the flexible circuit board 40 and prevents unnecessary contact wear or bending damage caused by deformation of the flexible circuit board 40. Specifically, the relief groove restrains the flexible circuit board 40 in a direction perpendicular to the first direction X, allowing the flexible circuit board 40 to be restrained in multiple directions between the first stopper 50 and the second stopper 60. This ensures that the flexible circuit board 40 maintains its illustrated shape, thereby protecting the flexible circuit board 40 and improving the stability and reliability of the electrical connection of the flexible circuit board 40.

[0039] In addition, in some embodiments, the first limiting member 50 causes the flexible circuit board 40 to abut against the hole wall of the first through hole 21 , and the second limiting member 60 creates a gap between the flexible circuit board 40 and the first hole wall 311 .

[0040] Through such a setting, the first limit member 50 presses the flexible circuit board 40 against the fourth hole wall 212 of the first through hole 21, so that the flexible circuit board 40 abuts against the fourth hole wall 212 of the first through hole 21, thereby preventing the portion of the flexible circuit board 40 in the first through hole 21 from moving or deforming, so that the flexible circuit board 40 is completely fixed in the first through hole 21, which is conducive to the portion of the flexible circuit board 40 passing through the first through hole 21 to maintain its shape unchanged, thereby avoiding the portion of the flexible circuit board 40 passing through the first through hole 21 from bending and damage.

[0041] The second limiting member 60 creates a gap between the flexible circuit board 40 and the first hole wall 311 , thereby preventing the first hole wall 311 from contacting the flexible circuit board 40 and causing wear on the flexible circuit board 40 .

[0042] In some embodiments, as Figure 1 As shown, the electronic device may further include a housing 10, a first electronic device 1, and a second electronic device 2. The first plate-like structure 20, the second plate-like structure 30, the flexible circuit board 40, the first stopper 50, and the second stopper 60 are all disposed within the housing 10. The first electronic device 1 is disposed on a side of the first plate-like structure 20 facing away from the second plate-like structure 30, and the second electronic device 2 is disposed on a side of the second plate-like structure 30 facing away from the first plate-like structure 20. One end of the flexible circuit board 40 is electrically connected to the first electronic device 1, and the other end of the flexible circuit board 40 passes through the first through hole 21 and the second through hole 31 and is electrically connected to the second electronic device 2.

[0043] The housing 10 protects the first electronic device 1, the second electronic device 2, the first plate-like structure 20, the second plate-like structure 30, the flexible printed circuit board 40, the first retaining member 50, and the second retaining member 60 from collision. One end of the flexible printed circuit board 40, extending through the first through-hole 21, is electrically connected to the first electronic device 1. The other end of the flexible printed circuit board 40, extending through the second through-hole 31, is electrically connected to the second electronic device 2. This allows signal transmission between the first and second electronic devices 1, 2, via the flexible printed circuit board 40, facilitating communication between the first and second electronic devices 1, 2.

[0044] It should be noted that the first electronic device 1 may be a display screen of an electronic device, and the second electronic device may be a motherboard of the electronic device. Of course, the first and second electronic devices may also be other components of the electronic device, for example, the first electronic device may be a camera and the second electronic device may be a motherboard. This is not limited in this embodiment of the present application.

[0045] In addition, in some embodiments, the first through hole 21 has a third hole wall 211 and a fourth hole wall 212 arranged relatively to each other, the orthographic projection of the third hole wall 211 on the second plate-like structure 30 is located between the first hole wall 311 and the second hole wall 312, the orthographic projection of the fourth hole wall 212 on the second plate-like structure 30 is located outside the second through hole 31, and the distance between the fourth hole wall 212 and the first hole wall 311 is smaller than the distance between the fourth hole wall 212 and the second hole wall 312; the first limit member 50 limits the flexible circuit board 40 from moving in the direction close to the third hole wall 211.

[0046] This arrangement is equivalent to misaligning the centerline of the first through-hole 21 with the centerline of the second through-hole 31. This, combined with the first stopper 50 blocking the overlapping portion of the first through-hole 21 and the second through-hole 31, prevents dust from passing through the second through-hole 31 and entering the motherboard area, potentially damaging electronic components. Specifically, the partial overlap of the first and second through-holes and the opposing positional limits of the first and second stoppers 50 and 60 in this embodiment not only maintain the flexible circuit board in the illustrated, pre-set, multiple-bend configuration to protect the flexible circuit board 40, but also minimizes the detour distance of the flexible circuit board 40 while enhancing the dustproofing of the electronic device. This prevents dust from easily entering the electronic device through the first and second through-holes, potentially damaging electronic components, due to the direct connection between the first and second through-holes. Furthermore, the unnecessary cost increase associated with the excessive detour distance of the flexible circuit board 40 due to the complete misalignment of the first and second through-holes is reduced.

[0047] Additionally, in some embodiments, Figure 3 As shown, the first limiting member 50 is connected to the second limiting member 60 , and the second limiting member 60 has a connecting portion 70 , which is connected to the first limiting member 50 .

[0048] This arrangement, with the connection portion 70 bent toward the first retaining member 50, facilitates the flexible circuit board 40 being more conveniently sandwiched between the first retaining member 50 and the second retaining member 60 during installation. More importantly, the second retaining member 60 is connected to the first retaining member 50 via the connection portion 70, enabling the first retaining member 50 to limit the second retaining member 60 in the first direction via the connection portion 70, thereby restricting the second retaining member 60 from moving away from the second through-hole 31. This improves the reliability and stability of the second retaining member 60's restraining effect on the flexible circuit board 40. Furthermore, the second retaining member 60 can also limit the first retaining member 50 in the first direction via the connection portion 70, restricting the first retaining member 50 from moving toward the second through-hole 31, thereby preventing the first retaining member 50 from slipping out of the first through-hole 21 and causing the flexible circuit board 40 to wobble and deform within the first through-hole 21. The first limiting member 50 is connected to the second limiting member 60, and the second limiting member 60 has a connecting portion 70 that bends toward the first limiting member 50 and extends along the first direction. The connecting portion 70 is connected to the first limiting member 50, so that the first limiting member 50 and the second limiting member 60 are limited to each other in the first direction through the connecting portion 70, preventing the first limiting member 50 and the second limiting member 60 from becoming loose or falling off and being unable to reliably and stably limit the flexible circuit board 40.

[0049] In addition, in some embodiments, the first limiting member 50 and the second limiting member 60 are made of elastic material, so that the relative position between the first limiting member 50 and the second limiting member 60 is adjustable.

[0050] Through such a setting, that is, the first limiting member 50 and the second limiting member 60 are made of elastic material, when force is applied to the second limiting member 60, the connecting portion 70 of the second limiting member 60 can be deformed, so that the angle between the second limiting member 60 and the first limiting member 50 is adjusted, thereby changing the relative position of the first limiting member 50 and the second limiting member 60, which is beneficial to the installation of the flexible circuit board 40 and the first limiting member 50 and the second limiting member 60.

[0051] In some embodiments, the first limiting member 50 and the second limiting member 60 are integrally formed of silicone.

[0052] Specifically, during the installation of the electronic device, the flexible circuit board 40 can be passed through the first through hole 21, and then the first limiting member 50 can be embedded in the first through hole 21. Figure 5 Then, force is applied to the second retaining member 60, causing the second retaining member 60 to deform through the connecting portion 70 and flip away from the first retaining member 50. This increases the angle between the second retaining member 60 and the first retaining member 50, facilitating the passage of the flexible circuit board 40 through the gap between the second retaining member 60 and the first retaining member 50. After the flexible circuit board 40 passes through the second through-hole 31, the force applied to the second retaining member 60 is released, causing the second retaining member 60 to reset. The angle between the second retaining member 60 and the first retaining member 50 decreases, thereby clamping the flexible circuit board 40 between the first and second retaining members 50. Optionally, when the second retaining member 60 is in the reset state, the surface of the second retaining member 60 facing the first retaining member 50 is parallel to the first retaining member 50. When the second retaining member 60 is in the flipped state, the surface of the second retaining member 60 facing the first retaining member 50 is perpendicular to the first retaining member 50.

[0053] Optionally, when the flexible circuit board 40 is in a preset configuration, the flexible circuit board 40 abuts against the second stopper 60 and maintains a gap with the second hole wall 312. The second stopper 60 blocks the flexible circuit board 40 from moving toward the first hole wall 311 to prevent the flexible circuit board 40 from contacting and abrading the first hole wall 311. At the same time, the second electronic device 2 is disposed on a side of the second hole wall 312 away from the first hole wall 311, thereby utilizing the bending deformation potential energy of the flexible circuit board 40 to maintain a gap between the flexible circuit board 40 and the second hole wall 312, thereby preventing the flexible circuit board 40 from contacting and abrading the second hole wall 312. In other words, through the design of the embodiment of the present application, the flexible circuit board 40 can always be spaced apart from the first hole wall 311 and the second hole wall 312, respectively, thereby effectively preventing wear and damage to the flexible circuit board 40.

[0054] In addition, in some embodiments, the side of the second limiting member 60 close to the first plate structure 20 is fixedly connected to the first plate structure 20; or the side of the second limiting member 60 close to the second plate structure 30 is fixedly connected to the second plate structure 30.

[0055] Through such a setting, when the second limiting member 60 is fixedly connected to the first plate-like structure 20, it is equivalent to the second limiting member 60 and the first plate-like structure 20 becoming one, so that when the second limiting member 60 is connected to the first limiting member 50 through the connecting portion 70, once the first limiting member 50 is forced to detach from the first through hole 21, the force of the first limiting member 50 is transmitted to the second limiting member 60, and the second limiting member 60 is fixed by the first plate-like structure 20, which is equivalent to the first limiting member 50 being subject to the limiting effect of the first plate-like structure 20, so that the first limiting member 50 is fixed, and thus the first limiting member 50 is not easily detached from the first through hole 21. When the second limiting member 60 is fixedly connected to the second plate-like structure 30, it is equivalent to the second limiting member 60 and the second plate-like structure 30 becoming one, so that when the second limiting member 60 is connected to the first limiting member 50 through the connecting portion 70, once the first limiting member 50 is forced to detach from the first through hole 21, the force of the first limiting member 50 is transmitted to the second limiting member 60, and the second limiting member 60 is fixed by the second plate-like structure 30, which is equivalent to the first limiting member 50 being subject to the limiting effect of the second plate-like structure 30, so that the first limiting member 50 is fixed, and thus the first limiting member 50 is not easily detached from the first through hole 21.

[0056] Furthermore, when the second limiting member 60 is fixedly connected to the first plate-like structure 20, it is equivalent to the second limiting member 60 and the first plate-like structure 20 becoming one piece. If the first limiting member 50 and the second limiting member 60 are not connected, the second limiting member 60 is still fixed by the first plate-like structure 20, making it difficult for the second limiting member 60 to shake, thereby improving the second limiting member 60's ability to limit the flexible circuit board 40. When the second limiting member 60 is fixedly connected to the second plate-like structure 30, it is equivalent to the second limiting member 60 and the second plate-like structure 30 becoming one piece. If the first limiting member 50 and the second limiting member 60 are not connected, the second limiting member 60 is still fixed by the second plate-like structure 30, making it difficult for the second limiting member 60 to shake, thereby improving the second limiting member 60's ability to limit the flexible circuit board 40.

[0057] It should be noted that in the embodiment of the present application, the second stopper 60 can be bonded to the first plate-like structure 20 by adhesive, or the second stopper 60 can be bonded to the second plate-like structure 30 by adhesive. The adhesive can be double-sided tape or curing adhesive. The specific type of adhesive is not limited in the embodiment of the present application.

[0058] Additionally, in some embodiments, Figure 7 As shown, the first stopper 50 further includes a second portion 51 located outside the first through-hole 21. The second portion 51 is connected to the first portion 501. The second portion 51 is located between the first plate-like structure 20 and the second plate-like structure 30. The orthographic projection of the second portion 51 on the first plate-like structure 20 extends outside the first through-hole 21, so that a portion of the second portion 51 is overlapped between the first plate-like structure 20 and the second plate-like structure 30, thereby limiting the movement of the first stopper 50 away from the second plate-like structure 30.

[0059] With this arrangement, when the first stopper 50 moves in a direction away from the second plate-like structure 30, the second portion 51 abuts against the first plate-like structure 20, and the first plate-like structure 20 applies resistance to the second portion 51, thereby blocking the second portion 51. The second portion 51 then transmits the resistance to the first portion 501 of the first stopper 50, thereby blocking the first portion 501 of the first stopper 50 and preventing the first portion 501 of the first stopper 50 from moving in a direction away from the second plate-like structure 30. This, in turn, prevents the first stopper 50 from moving in a direction away from the second plate-like structure 30. Specifically, by arranging the orthographic projection of the second portion 51 on the first plate-like structure 20 to extend outside the first through-hole 21, such that a portion of the second portion 51 is superimposed between the first plate-like structure 20 and the second plate-like structure 30, the first stopper 50 can be effectively prevented from moving in a direction away from the second plate-like structure 30, making it difficult for the first stopper 50 to disengage from the first through-hole 21 in a direction away from the second plate-like structure 30.

[0060] It should be noted that a limiting groove may be provided on the surface of the first plate-like structure 20 facing the second plate-like structure 30, and the second portion 51 may be located in the limiting groove, so that when the second portion 51 moves in a direction away from the second plate-like structure 30, the second portion 51 is blocked by the bottom of the limiting groove. At the same time, the limiting groove can also limit the movement of the first limiting member 50 in a direction perpendicular to the first direction.

[0061] In addition, in an embodiment of the present application, when the second limiting member 60 is connected to the first plate-like structure 20 or the second plate-like structure 30, the second part 51 of the first limiting member 50 can be simultaneously located between the first plate-like structure 20 and the second plate-like structure 30. At this time, the second part 51 can limit the first limiting member 50 from moving in a direction away from the second plate-like structure 30, and the second limiting member 60 can limit the first limiting member 50 from moving in a direction close to the second plate-like structure 30, so that the first limiting member 50 can be fixed more firmly in the first through hole 21, thereby making it difficult for the first limiting member 50 to detach from the first through hole 21.

[0062] Additionally, in some embodiments, Figure 2As shown, a limiting protrusion 201 is provided on one side of the first plate-like structure 20 close to the second plate-like structure 30, and the limiting protrusion 201 is arranged opposite to the second part 51 of a part stacked between the first plate-like structure 20 and the second plate-like structure 30 to limit the first limiting member 50 from moving in a direction perpendicular to the first direction X.

[0063] With this arrangement, once the first stopper 50 is subjected to force, the first portion 501 of the first stopper may rotate within the first through hole 21. The first portion 501 will then drive the second portion 51 to rotate, but the second portion 51 will be blocked by the stopper protrusion 201, preventing the second portion 51 from rotating along with the first portion 501. This, in turn, blocks the first portion 501, preventing it from rotating. In other words, the provision of the stopper protrusion 201 prevents the first stopper 50 from rotating along the first through hole 21. In other words, in this embodiment of the present application, by providing the stopper protrusion 201 and positioning the second portion 51 of the first stopper 50 between the first plate-like structure 20 and the second plate-like structure 30, the first stopper 50 can be constrained in the first direction X, preventing the first stopper 50 from disengaging from the first through hole 21. Furthermore, the first stopper 50 can be prevented from rotating within the first through hole 21.

[0064] Additionally, in some embodiments, Figure 2 As shown, a deformable boss 52 is provided circumferentially of the first limiting member 50. When the first limiting member 50 is clamped in the first through hole 21, the boss 52 abuts against the hole wall of the first through hole 21, and the boss 52 causes the flexible circuit board 40 to abut against the hole wall of the first through hole 21.

[0065] By providing a deformable boss 52, when the first retaining member 50 is positioned within the first through-hole 21, the boss 52 not only abuts against the wall of the first through-hole 21 but also compresses the flexible circuit board 40, forcing the flexible circuit board 40 into abutment with the wall of the first through-hole 21. Furthermore, because the boss 52 is deformable, it exerts a compressive force on the flexible circuit board 40, preventing damage to the flexible circuit board 40. In other words, the flexible circuit board 40 exerts a reaction force on the boss 52, allowing the boss 52 to tightly compress the flexible circuit board 40 and minimizing damage to the flexible circuit board 40. Furthermore, by providing the boss 52, the first retaining member 50 is more securely fixed within the first through-hole 21, preventing the first retaining member 50 from easily detaching from the first through-hole 21.

[0066] It should be noted that the boss 52 can be formed of an elastic material.

[0067] It should also be noted that in the embodiment of the present application, both the first limiting member 50 and the second limiting member 60 can be limiting members formed of silicone. Of course, the second limiting member 60 can be foam and the first limiting member 50 can be a silicone plug. This embodiment of the present application does not limit this.

[0068] In the embodiment of the present application, since the first plate-like structure 20 and the second plate-like structure 30 are stacked along the first direction X, the first plate-like structure 20 is provided with a first through hole 21, and the second plate-like structure 30 is provided with a second through hole 31, the flexible circuit board 40 can pass through the first through hole 21 and the second through hole 31. Since the first portion 501 of the first limiting member 50 is provided in the first through hole 21, the first portion 501 of the first limiting member 50 can limit the movement of the flexible circuit board 40 within the first through hole 21, which is equivalent to limiting the flexible circuit board 40 in the first through hole 21. Because the second stopper 60 is located between the first plate-like structure 20 and the second plate-like structure 30, the orthographic projection of the second stopper 60 on the second plate-like structure 30 extends across the first hole wall 311 to between the first hole wall 311 and the second hole wall 312. Therefore, after the flexible circuit board 40 abuts the second stopper 60, the second stopper 60 can limit the flexible circuit board 40, preventing the flexible circuit board 40 from moving toward the first hole wall 311, thereby preventing the flexible circuit board 40 from contacting the first hole wall 311. That is, in the embodiment of the present application, by providing the first stopper 50 and the second stopper 60, the first stopper 50 limits the flexible circuit board 40 in the first through hole 21, and the second stopper 60 limits the flexible circuit board 40 from contacting the first hole wall 311, thereby preventing the first hole wall 311 from abrading the flexible circuit board 40, thereby preventing the flexible circuit board 40 from being easily damaged, thereby improving the service life of the flexible circuit board 40.

[0069] An assembly method is applied to the assembly of the electronic device in the above embodiment, such as Figure 9 As shown, the assembly method includes:

[0070] Step 901: Provide a first position-limiting member and a second position-limiting member, wherein the second position-limiting member has a connecting portion connected to the first position-limiting member.

[0071] Step 902: inserting a flexible printed circuit board into the first through hole.

[0072] Step 903: Install the first limiting member in the first through hole, and rotate the second limiting member to increase the angle between the second limiting member and the first limiting member.

[0073] Among them, the second limit member can be rotated so that the surface of the second limit member facing the first limit member is perpendicular to the second limit member, so that the second limit member avoids the flexible circuit board, so that the flexible circuit board can easily pass through the gap between the first limit member and the second limit member to pass through the second through hole.

[0074] Step 904 : inserting the flexible circuit board into the second through hole, resetting the second limiting member, and fixing the second limiting member so that the flexible circuit board abuts against the second limiting member.

[0075] After the flexible circuit board is inserted into the second through-hole, the second stopper can be reset, i.e., the surface of the second stopper facing the first stopper is parallel to the first stopper. At this point, the flexible circuit board located between the first plate-like structure and the second plate-like structure is sandwiched between the first and second stoppers. Subsequently, force is applied to the flexible circuit board passing through the second through-hole to cause the flexible circuit board to abut against the second stopper. The second stopper blocks the flexible circuit board, preventing it from contacting the first hole wall of the second through-hole.
