Abstract
Description
Technical Field
[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology
[0002] Foldable electronic devices typically feature flexible circuit boards at their folding points. These boards are threaded through hinge assemblies, which have mounting slots and holes at the bottom of these slots. The flexible circuit boards are then pressed and secured by a press-fit component, with waterproof sealant applied to the outer periphery of the press-fit component. Assembly gaps exist between the flexible circuit boards and the side walls and bottom of the slots, creating interconnected channels for excess adhesive. During dispensing, adhesive from the outer periphery of the press-fit component can easily seep into these channels from both ends of the flexible circuit board, causing adhesion between the frame and the flexible circuit board. This hinders normal folding of the flexible circuit board, resulting in abnormal noises during opening and closing, and can easily cause the flexible circuit board to bend and break, significantly reducing the overall reliability and lifespan of the device. Summary of the Invention
[0003] The purpose of this application embodiment is to provide an electronic device that can continuously block the penetration of adhesive through a first sealing element, so that the folding action of the flexible circuit board can remain smooth, reducing the probability of abnormal noise during the opening and closing process of the electronic device and the probability of bending and breaking of the flexible circuit board, thereby effectively improving the reliability and service life of the electronic device during long-term use.
[0004] In a first aspect, embodiments of this application provide an electronic device, including: a first frame and a second frame, the first frame and the second frame being rotatably connected by a hinge assembly, the electronic device further including a flexible circuit board, the flexible circuit board being disposed through the hinge assembly, the first frame and the second frame being electrically connected through the flexible circuit board.
[0005] The hinge assembly is provided with a mounting groove and a slot hole. The slot hole is located at the bottom of the mounting groove. The flexible circuit board passes through the slot hole and is pressed into the bottom of the mounting groove by a pressing component. The flexible circuit board includes a connecting wire body and a reinforcing component. The reinforcing component is provided on the side of the connecting wire body facing the slot hole. The reinforcing component extends along a first direction and both ends of the reinforcing component extend out of the connecting wire body. The first direction is the width direction of the connecting wire body.
[0006] Both ends of the reinforcing member are provided with a first protrusion and a second protrusion. The first protrusion is located on the side of the second protrusion away from the connecting wire body. A first sealing member is sleeved on the second protrusion. The size of the first protrusion in the second direction is larger than the size of the second protrusion in the second direction, so as to limit the first sealing member in the first direction. The second direction is perpendicular to the first direction.
[0007] The first seal abuts against the connecting wire body, and the first seal fits the bottom and sidewall of the slot.
[0008] In this embodiment, the electronic device includes a first frame and a second frame, which are rotatably connected by a hinge assembly. The electronic device also includes a flexible circuit board, which passes through the hinge assembly and is used for electrical signal transmission between the first and second frames. The hinge assembly has a mounting groove and a slot, with the slot at the bottom of the mounting groove. The mounting groove accommodates components such as pressing parts, while the slot allows the flexible circuit board to pass through. The flexible circuit board passes through the slot and is pressed and positioned at the bottom of the mounting groove by the pressing parts. The flexible circuit board includes a connecting wire body and a reinforcing member. The reinforcing member is located on the side of the connecting wire body facing the slot, extending along a first direction, which is the width direction of the connecting wire body. Both ends of the reinforcing member extend beyond the connecting wire body, improving the structural rigidity at the corresponding location and reducing deformation damage caused by repeated bending of the flexible circuit board. The reinforcing member has a first protrusion and a second protrusion at both ends. The first protrusion is located on the side of the second protrusion away from the connecting wire body, and a first sealing element is fitted onto the second protrusion. The second direction is perpendicular to the first direction. The first protrusion is larger in the second direction than the second protrusion, which can provide a stop and limit in the first direction for the first sealing element fitted onto the second protrusion, thus restricting the first sealing element from shifting along the first direction. The first sealing element abuts against the connecting wire body and conforms to the bottom and sidewall of the slot. In practical applications, the slot, the connecting wire body, and the reinforcing member together form a first overflow channel for the flow of adhesive. The first sealing member is assembled at the end of the reinforcing member and simultaneously abuts against the connecting wire body, the bottom of the slot, and the sidewall, thus sealing the end of the first overflow channel. During dispensing operations, this prevents external adhesive from seeping inward, avoiding the flow of adhesive into the hinge assembly and causing the flexible circuit board to stick. This ensures smooth folding of the flexible circuit board, reduces the risk of abnormal noise during the opening and closing of electronic devices, and also reduces the problem of flexible circuit board bending and damage caused by adhesive erosion, thereby improving the long-term reliability and service life of the entire machine.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, 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 objects are in an "or" relationship.
[0026] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this application provides an electronic device 10, including: a first frame 110 and a second frame 120, the first frame 110 and the second frame 120 being rotatably connected by a hinge assembly 130. The electronic device 10 also includes a flexible circuit board 140, which is disposed through the hinge assembly 130. The first frame 110 and the second frame 120 are electrically connected through the flexible circuit board 140.
[0028] The hinge assembly 130 is provided with a mounting groove 102 and a slot 101. The slot 101 is located at the bottom of the mounting groove 102. The flexible circuit board 140 passes through the slot 101 and is pressed into the bottom of the mounting groove 102 by the pressing member 700. The flexible circuit board 140 includes a connecting wire body 200 and a reinforcing member 400. The reinforcing member 400 is disposed on the side of the connecting wire body 200 facing the slot 101. The reinforcing member 400 extends along a first direction and both ends of the reinforcing member 400 extend out of the connecting wire body 200. The first direction is the width direction of the connecting wire body 200.
[0029] The reinforcing member 400 has a first protrusion 410 and a second protrusion 411 at both ends. The first protrusion 410 is located on the side of the second protrusion 411 away from the connecting wire body 200. A first sealing member 300 is sleeved on the second protrusion 411. The size of the first protrusion 410 in the second direction is larger than the size of the second protrusion 411 in the second direction, so as to limit the first sealing member 300 in the first direction. The second direction is perpendicular to the first direction.
[0030] The first sealing element 300 abuts against the connecting wire body 200, and the first sealing element 300 fits the bottom and sidewall of the slot 101.
[0031] In this embodiment, the electronic device 10 includes a first frame 110 and a second frame 120, which are rotatably connected by a hinge assembly 130. The electronic device 10 also includes a flexible circuit board 140, which passes through the hinge assembly 130 and is used to transmit electrical signals between the first frame 110 and the second frame 120. The hinge assembly 130 has a mounting groove 102 and a slot 101. The slot 101 is formed at the bottom of the mounting groove 102, which accommodates components such as a pressing member 700. The slot 101 allows the flexible circuit board 140 to pass through. The flexible circuit board 140 passes through the slot 101 and is pressed and positioned at the bottom of the mounting groove 102 by the pressing member 700. The flexible circuit board 140 includes a connecting wire body 200 and a reinforcing member 400. The reinforcing member 400 is provided on the side of the connecting wire body 200 facing the slot 101. The reinforcing member 400 extends along a first direction, which is the width direction of the connecting wire body 200. Both ends of the reinforcing member 400 extend beyond the connecting wire body 200. The reinforcing member 400 can improve the structural rigidity at the corresponding position and reduce deformation damage caused by repeated bending of the flexible circuit board 140. Both ends of the reinforcing member 400 are provided with a first protrusion 410 and a second protrusion 411. The first protrusion 410 is located on the side of the second protrusion 411 away from the connecting wire body 200. A first sealing member 300 is sleeved on the second protrusion 411. The second direction is perpendicular to the first direction. The first protrusion 410 is larger in the second direction than the second protrusion 411, which can stop and limit the first sealing member 300 sleeved on the second protrusion 411 in the first direction, thus constraining the first sealing member 300 from shifting along the first direction. The first sealing member 300 abuts against the connecting wire body 200 and fits the bottom and sidewall of the slot 101. In practical applications, the slot 101, the connecting wire body 200, and the reinforcing member 400 together form a first overflow channel for the flow of adhesive. The first sealing member 300 is assembled at the end of the reinforcing member 400 and simultaneously abuts against the connecting wire body 200, the bottom of the slot 101, and the side wall, thus sealing the end of the first overflow channel. During dispensing operations, it prevents external adhesive from seeping inward, avoids adhesive from flowing into the hinge assembly 130 and causing the flexible circuit board 140 to stick, ensures smooth folding of the flexible circuit board 140, reduces the risk of abnormal noise during the opening and closing of the electronic device 10, and also reduces the problem of bending and damage to the flexible circuit board 140 caused by adhesive erosion, thereby improving the long-term reliability and service life of the entire machine. Figure 3 The middle arrow X is used to indicate the first direction. Figure 3 The arrow Y in the diagram is used to indicate a second direction, which is perpendicular to the first direction.
[0032] For example, the first direction is the width direction of the connecting line body 200, and the second direction is the length direction of the connecting line body 200.
[0033] For example, the first direction is the axial direction of the hinge assembly 130, and the second direction is the radial direction of the hinge assembly 130.
[0034] Figure 3 The thick solid line A in the figure is used to indicate the dispensing path of the adhesive during the dispensing operation.
[0035] Figure 4 The arrows in the diagram are used to indicate the flow path of the adhesive.
[0036] For example, electronic device 10 includes, but is not limited to, mobile phones, laptops, tablets, and other bendable electronic devices with built-in flexible circuit boards 140.
[0037] like Figure 2 As shown, in some embodiments of this application, along the first direction, the connecting line body 200 is provided with clearance areas 201 on both sides, and the first sealing member 300 is provided in the clearance area 201. The outline of the clearance area 201 is adapted to the outline of the first sealing member 300.
[0038] In the above embodiment, the connecting wire body 200 has corresponding clearance areas 201 on both sides along the first direction. The clearance areas 201 are matched with the outer contour of the first sealing element 300, providing a suitable assembly space for the first sealing element 300. The clearance areas 201 can eliminate interference from structural protrusions on the surface of the connecting wire body 200, allowing the first sealing element 300 to fully fit the connecting wire body 200. At the same time, it can also limit the shaking and displacement of the first sealing element 300, ensuring the stability of the assembly position of the first sealing element 300, continuously maintaining the sealing effect on the first overflow channel, and ensuring the working stability of the anti-seepage adhesive structure.
[0039] It should be noted that when the connecting wire body 200 extends fully to the second protrusion 411 of the reinforcing member 400, a protrusion is formed, and the clearance area 201 is formed by cutting off the protrusion. The setting of the clearance area 201 can facilitate the first sealing member 300 to fit more closely to the connecting wire body 200, thereby ensuring the sealing effect of the first sealing member 300.
[0040] A stepped structure can be formed between the second protruding part 411 and the connecting wire body 200. The stepped structure can form a flow channel for the flow of adhesive. The first sealing member 300 can fit into the stepped structure to block the flow channel and prevent the adhesive from seeping in along the gaps of the stepped structure.
[0041] For example, the first seal 300 can adopt a rectangular frame structure, and the outline of the avoidance area 201 is set as a straight surface. The straight surface is completely fitted with the side of the rectangular frame. Full fit is achieved by relying on contour matching, which simplifies the machining difficulty of the shape of the first seal 300.
[0042] For example, the first seal 300 can be assembled with the second protrusion 411 by means of adhesive backing, glue fixation, and in-mold injection molding.
[0043] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments of this application, along the second direction, the opposite sides of the first protrusion 410 extend out of the second protrusion 411; the side of the first protrusion 410 near the second protrusion 411 abuts against the first seal 300.
[0044] In the above embodiment, the first protrusion 410 extends from both sides of the second protrusion 411 along the second direction, forming a double-sided limiting on both sides of the second protrusion 411. This allows for uniform limiting and constraint of the first sealing member 300 sleeved on the second protrusion 411 from two points in the second direction, thereby improving the assembly firmness of the first sealing member 300. This arrangement helps to offset the minor structural deformation caused by vibration of the electronic device 10 and changes in ambient temperature, avoiding the problem of unilateral force displacement and local sealing failure of the first sealing member 300, ensuring that the first sealing member 300 maintains a fully circumferential sealing state, and stably achieving multiple technical effects such as preventing glue leakage, preventing adhesion, and suppressing abnormal opening and closing noise.
[0045] like Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments of this application, the electronic device 10 further includes a second seal 500;
[0046] Along the first direction, an assembly gap 401 is formed between the first protrusion 410 and the sidewall of the slot 101, and the second seal 500 fills the assembly gap 401.
[0047] In the above embodiment, the assembly gap 401 between the first protrusion 410 and the sidewall of the slot 101 constitutes a second overflow channel, which is a weak point where adhesive is prone to accumulate and penetrate. The second seal 500 fills the interior of the assembly gap 401, blocking the path of adhesive seeping inward along the second overflow channel. The second seal 500 and the first seal 300 form a double-layer anti-seepage adhesive protection system, sealing the second overflow channel and the first overflow channel respectively, avoiding the risk of localized adhesive leakage and seepage inside the slot 101, and ensuring the folding flexibility and overall structural integrity of the flexible circuit board 140.
[0048] For example, the second seal 500 is made of soft rubber material, and the second seal 500 is assembled with the sidewalls of the first protrusion 410 and the slot 101 using an interference fit or a zero clearance fit. The soft rubber material has elastic deformation capability, which can compensate for the machining tolerances and assembly deviations of the parts, so that the second seal 500 fits tightly against the two sidewalls of the assembly gap 401 and continuously maintains the sealing state.
[0049] For example, the second seal 500 can be made of silicone or foam cotton. After assembly, it relies on its own elasticity to continuously press into the assembly gap 401, and the anti-seepage effect is stable and long-lasting.
[0050] like Figure 14 As shown, in some embodiments of this application, the electronic device 10 further includes an adhesive layer 600;
[0051] The reinforcing member 400 is bonded to the bottom of the slot 101 via the adhesive layer 600 on the side opposite to the connecting line body 200.
[0052] In the above embodiment, the adhesive layer 600 is disposed between the reinforcing member 400 and the bottom of the slot 101. The adhesive layer 600 can fix the reinforcing member 400 inside the slot 101, restricting the positional movement of the reinforcing member 400 relative to the slot 101. After the assembly position of the reinforcing member 400 is fixed, it is also beneficial to maintain the assembly accuracy of the first protrusion 410, the second protrusion 411, the first seal 300, and the second seal 500, ensuring that the first seal 300 and the second seal 500 continuously maintain the preset fit state and stably achieve the anti-seepage protection effect.
[0053] For example, the adhesive layer 600 can be used to bond and fix the reinforcing part 400 by using double-sided adhesive and liquid dispensing curing layer, which can meet the fixing requirements of narrow assembly space.
[0054] For example, the first sealing element 300 is sleeved on the second protrusion 411. The adhesive layer 600 covers the bottom wall of the slot 101, and the first sealing element 300 is bonded to the bottom wall of the slot 101 through the adhesive layer 600, so that the first sealing element 300 stably abuts against the bottom wall of the slot 101, effectively ensuring the sealing fit performance between the first sealing element 300 and the bottom wall of the slot 101.
[0055] like Figure 2 and Figure 14 As shown, in some embodiments of this application, the pressing member 700 includes a bracket body 710 and a fastener 720;
[0056] The bracket body 710 is located in the mounting groove 102;
[0057] The bottom of the mounting slot 102 is provided with at least two threaded holes 103. Along the first direction, threaded holes 103 are provided on both sides of the slot 101. Fasteners 720 pass through the bracket body 710 and are threadedly connected to the threaded holes 103.
[0058] In the above embodiment, the bracket body 710 is housed inside the mounting groove 102, which can clamp and limit the connection wire body 200. Threaded holes 103 are symmetrically arranged on both sides of the groove hole 101 at the bottom of the mounting groove 102. Fasteners 720 penetrate the bracket body 710 and are threadedly locked to the threaded holes 103, achieving stable fixation of the bracket body 710, ensuring uniform force distribution without warping, and stably clamping and fixing the flexible circuit board 140, preventing displacement of the flexible circuit board 140 during folding, and providing a stable assembly base for the sealing structure inside the groove hole 101.
[0059] For example, the threaded holes 103 are symmetrically arranged, which can make the support body 710 bear the force evenly, and the fasteners 720 can be standard fastening components such as screws and bolts, so that the assembly and fixing reliability is high.
[0060] For example, the press-fit component 700 is made of rigid plastic or metal.
[0061] like Figure 2 and Figure 14 As shown, in some embodiments of this application, the press-fit member 700 further includes a third seal member 730;
[0062] The third seal 730 is in a compressed state and is located between the bracket body 710 and the connecting wire body 200, with the first seal 300 abutting against the third seal 730.
[0063] In the above embodiment, the third sealing member 730 is assembled in a compressed state between the bracket body 710 and the connecting wire body 200. The compressed and deformed third sealing member 730 can press and limit the connecting wire body 200, improving the assembly and fixing stability of the connecting wire body 200. At the same time, the third sealing member 730 can fill the assembly gap between the bracket body 710 and the connecting wire body 200, preventing adhesive and impurities from invading into the slot from the pressing member side. The first sealing member 300 and the third sealing member 730 abut against each other, and the pressing member 700 forms a lateral constraint on the first sealing member 300. The two are adhered to form a continuous sealing barrier structure, which can prevent adhesive from seeping from the side of the first sealing member 300 near the pressing member 700 to the side of the first sealing member 300 near the connecting wire body 200, further improving the overall anti-seepage adhesive effect at the slot 101 position.
[0064] For example, the third seal 730 may be made of elastic foam, silicone pad, or thermoplastic polyurethane elastic gasket, which has excellent compression resilience and is not prone to failure under long-term pressure.
[0065] In some embodiments of this application, the reinforcing member 400 is bonded to the side of the connecting wire body 200 facing the bottom of the slot 101, and the reinforcing member 400 is located inside the slot 101.
[0066] In the above embodiment, the reinforcing member 400 is attached to the side of the connecting wire body 200 facing the bottom of the slot 101, and is entirely housed inside the slot 101. The location where the connecting wire body 200 passes through the slot 101 is an area prone to fatigue fracture due to repeated bending. The reinforcing member 400 can structurally strengthen the connecting wire body 200 in this area. At the same time, the reinforcing member 400 is constrained by the space of the slot 101, reducing the probability of the reinforcing member 400 shifting after assembly. This ensures that the first protrusion 410 and the second protrusion 411 at the end of the reinforcing member 400 are precisely aligned with the first sealing member 300, ensuring a stable and reliable assembly position and sealing effect of the first sealing member 300.
[0067] In some embodiments of this application, the first seal 300 is made of at least one of silicone, thermoplastic polyurethane, leather, and foam.
[0068] In the above embodiments, silicone, thermoplastic polyurethane, leather, and foam all possess elastic deformation capabilities. Using these materials to prepare the first sealing element 300 allows it to deform under external force, ensuring a tight fit between the first sealing element 300 and the bottom and side walls of the connecting wire body 200 and the slot 101, maintaining a sealed contact and preventing adhesive penetration. Different materials can be flexibly selected according to the internal working conditions of the equipment to meet different requirements for heat resistance, wear resistance, and compression durability.
[0069] like Figure 2 As shown, in some embodiments of this application, the connector body 200 includes a receiving section 210 and an extension section 220; the receiving section 210 is disposed in the slot 101, and the extension section 220 extends from the receiving section 210 along a second direction and extends out of the slot 101.
[0070] In the above embodiment, the connector body 200 is divided into a receiving section 210 and an extension section 220. The receiving section 210 is arranged inside the slot 101, which provides space for the receiving section 210. The receiving section 210 is protected by a surrounding sealing structure. The extension section 220 extends from the receiving section 210 along a second direction and extends out of the slot 101. The second direction intersects with the first direction, thereby realizing the cross-regional wiring arrangement of the connector body 200 and meeting the electrical connection requirements between different components. At the same time, the receiving section 210 and the extension section 220 are laid out separately, which can avoid the connector body 200 being completely stored inside the slot, thus preventing limited bending space.
[0071] For example, the extension section 220 is provided with bending allowance to accommodate the opening and closing actions of electronic devices at 10 different angles, thus avoiding damage to the circuit structure due to bending and pulling.
