Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a PCB board with bending function. Background Technology

[0002] Flexible PCBs are of great significance in modern electronic device manufacturing, and are widely used in wearable devices, smart homes, aerospace, and many other fields. They can be bent to fit the internal space and functional requirements of devices, effectively improving space utilization and optimizing circuit layout. For example, in wearable devices, which need to conform to the curves of the human body, a flexible PCB makes the device more comfortable and allows for miniaturization. In the aerospace field, they can adapt to the complex spatial structure inside aircraft and meet special circuit design requirements. Currently, flexible PCBs typically require the following technologies in practical applications:

[0003] 1. The substrate material has high flexibility and bendability to ensure that the PCB board can be safely bent within a certain range without damaging the internal circuitry;

[0004] 2. Advanced circuit wiring and packaging technology ensures that the circuit maintains good electrical connection and performance stability during bending;

[0005] 3. Reliable protective coating technology protects the bent PCB board from external environmental corrosion;

[0006] 4. Component selection and layout methods that match the bending characteristics ensure that components can still function normally when the PCB board is bent.

[0007] Currently, various technologies and methods are employed to achieve the bending function of PCB boards. Some manufacturers use special flexible substrate materials, such as polyimide (PI) film, combined with flexible circuit printing technology to create bendable PCB boards. This method allows the PCB board to bend to a certain extent, but it has limitations in bending radius and the number of repeated bends. Other manufacturers use a rigid-flex PCB design, connecting rigid and flexible circuit boards through specific processes, utilizing the flexible portion to achieve bending functionality. However, this method is prone to stress concentration problems in the rigid-flex transition area, affecting the reliability and lifespan of the PCB board. Some manufacturers have attempted to manufacture bendable PCB boards using 3D printing technology. While it can achieve complex shape designs, there are still shortcomings in printing accuracy and material properties, resulting in unstable electrical performance and high costs.

[0008] However, the above methods have a prominent problem: the fixation and stability of the printed circuit board after bending are not good. Whether using flexible substrate materials or a combination of soft and rigid designs, there is a lack of effective fixation measures after the printed circuit board is bent to the required shape. It is easy for the shape to change due to external forces during use, which affects the performance of the equipment. Moreover, the existing fixation methods are often complex and unreliable, making it difficult to meet the needs of large-scale production and actual use. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a PCB board with bending function, which solves the problem of poor fixation and stability of printed circuit boards after bending. Regardless of whether flexible substrate materials or a combination of soft and rigid designs are used, there is a lack of effective fixation measures after the printed circuit board is bent to the required shape. It is easy for the shape to change due to external forces during use, which affects the performance of the equipment. Moreover, existing fixation methods are often complex and unreliable, making it difficult to meet the technical problems of large-scale production and actual use.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A PCB board with bending function includes a storage box. A printed circuit board body is disposed inside the storage box. A limiting mechanism for fixing the printed circuit board body is disposed inside the storage box. The limiting mechanism includes a rectangular limiting seat disposed inside the storage box. A quick-installation snap-fit ​​mechanism is disposed on the outer surface of the printed circuit board body. The snap-fit ​​mechanism includes a mounting block, two pressing rods, and two arc-shaped locking blocks. The mounting block is fixedly connected to the outer surface of the printed circuit board body. The two pressing rods are slidably connected inside the mounting block. The two arc-shaped locking blocks are respectively fixedly connected to the two pressing rods at their adjacent ends. A first spring is fixedly connected to the adjacent ends of the two arc-shaped locking blocks, and both first springs are fixedly connected inside the mounting block.

[0012] Preferably, the rectangular limiting seat has a set of slots inside.

[0013] Preferably, a support plate is fixedly connected inside the storage box.

[0014] Preferably, a set of second springs is fixedly connected inside the support plate.

[0015] Preferably, rubber pads are fixedly connected to the outer surfaces of both pressing rods, and two U-shaped soft rubber sleeves are fitted onto the outer surface of the printed circuit board body.

[0016] Preferably, the lower ends of both U-shaped soft rubber sleeves are fixedly connected with arc-shaped angle limiting blocks.

[0017] Preferably, both of the U-shaped soft rubber ferrules have a set of bolts threaded inside.

[0018] Preferably, a lid is fixedly connected to the upper end of the storage box, and a wiring port is fixedly connected to the outer surface of the storage box.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Pulling the mounting block will bend the printed circuit board (PCB) body. When the PCB body is bent to the required installation size, release the rectangular limit seat, which will slide out. At the same time, release the two pressing rods, and the first spring will return to its original deformation, pushing the two arc-shaped locking blocks to slide against the inner surface of the rectangular limit seat. The arc-shaped locking blocks will engage in the slots inside the rectangular limit seat, thus fixing the bent PCB body in the required bending state. Through the engagement of the arc-shaped locking blocks with the slots inside the rectangular limit seat, the PCB body can be precisely fixed in the required bending state. The quick fixing operation can be achieved by pushing the pressing rods and the rectangular limit seat, avoiding the unstable operation of pressing and maintaining the current position while tightening the screws. This greatly shortens the installation time and improves the efficiency of the production or assembly process.

[0021] 2. Two U-shaped soft rubber sleeves are fitted onto the outer surface of the printed circuit board body. By rotating two sets of bolts, they are made to fit against the outer surface of the printed circuit board body, thus fixing the U-shaped soft rubber sleeves to the printed circuit board body. When the printed circuit board body bends, it will cause the two arc-shaped angle limiting blocks fixedly connected at the lower end to move closer to each other. When the two arc-shaped angle limiting blocks fit together, they will limit the further bending of the printed circuit board body, thereby preventing the printed circuit board body from being damaged due to excessive bending and ensuring that it is used within a safe bending range.

[0028] This application provides a PCB board with bending functionality, effectively solving the problem of poor fixation and stability after bending of the printed circuit board. Regardless of whether flexible substrate materials or a rigid-soft hybrid design are used, there is a lack of effective fixing measures after the printed circuit board is bent to the required shape. This makes it prone to shape changes due to external forces during use, affecting equipment performance. Furthermore, existing fixing methods are often complex and unreliable, failing to meet the needs of large-scale production and practical use. Pulling the mounting block causes the printed circuit board body to bend. When the printed circuit board body bends to the required installation size, the rectangular limiting seat is released, and the rectangular limiting seat slides out. Simultaneously, the rectangular limiting seat is released... Opening two pressing rods causes the first spring to return to its original deformation, pushing two curved locking blocks to slide against the inner surface of the rectangular limiting seat. The curved locking blocks engage with the slots inside the rectangular limiting seat, thus fixing the bent printed circuit board body in place and maintaining it in the desired bending state. Through the engagement of the curved locking blocks with the slots inside the rectangular limiting seat, the printed circuit board body can be precisely fixed in the required bending state. Furthermore, the fixing operation can be quickly achieved by pushing the pressing rods and the rectangular limiting seat, avoiding the unstable operation of workers pressing to maintain the current position while simultaneously turning the screw. This greatly shortens the installation time and improves the efficiency of the production or assembly process.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem of poor fixation and stability of printed circuit boards after bending. Regardless of whether flexible substrate materials or a rigid-soft hybrid design are used, there is a lack of effective fixing measures after the printed circuit board is bent to the required shape. This makes it prone to shape changes due to external forces during use, affecting equipment performance. Furthermore, existing fixing methods are often complex and unreliable, failing to meet the needs of large-scale production and practical use. The overall concept is as follows: A PCB board with bending function includes a storage box 11. A printed circuit board body 12 is disposed inside the storage box 11. A limiting mechanism for fixing the printed circuit board body 12 is disposed inside the storage box 11. The limiting mechanism includes a rectangular limiting seat 13 disposed inside the storage box 11. A quick-installation snap-fit ​​mechanism is disposed on the outer surface of the printed circuit board body 12. The snap-fit ​​mechanism includes an mounting block 14, two pressing rods 15, and two arc-shaped locking blocks 16. The mounting block 14 is fixedly connected to the printed circuit board body 12. On the outer surface of the circuit board body 12, two pressing rods 15 are slidably connected to the inside of the mounting block 14. Two arc-shaped locking blocks 16 are respectively fixedly connected to the two pressing rods 15 at their close ends. A first spring 17 is fixedly connected to the close ends of the two arc-shaped locking blocks 16. Both first springs 17 are fixedly connected to the inside of the mounting block 14. Pressing the two pressing rods 15 inward causes the two pressing rods 15 to drive the two arc-shaped locking blocks 16 to slide inward and compress the first springs 17, causing them to retract. The end is fixed inside the storage box 11 by screws. Pulling the mounting block 14 causes the printed circuit board body 12 to bend. At this time, the operator manually presses the rectangular limiting seat 13 inward and slides it. When it bends to the required size for installation, the rectangular limiting seat 13 is released. The rectangular limiting seat 13 slides into the outer surface of the two arc-shaped locking blocks 16. At this time, the two pressing rods 15 are released. Under the action of the first spring 17, the two arc-shaped locking blocks 16 slide and fit against the inner surface of the rectangular limiting seat 13, thereby completing the fixation of the printed circuit board body 12.

[0031] The rectangular limiting seat 13 has a set of slots 18 inside, and two arc-shaped locking blocks 16 are adapted to the set of slots 18. A support plate 19 is fixedly connected inside the storage box 11. The rectangular limiting seat 13 is slidably connected inside the support plate 19. A set of second springs 21 is fixedly connected inside the support plate 19. The set of second springs 21 is fixedly connected to the outer surface of the slots 18. Rubber pads 22 are fixedly connected to the outer surface of the two pressing rods 15. Two U-shaped soft rubber sleeves 23 are fitted onto the outer surface of the printed circuit board body 12. Arc-shaped angle limiting blocks 24 are fixedly connected to the lower end of the two U-shaped soft rubber sleeves 23. The two arc-shaped angle limiting blocks 24 are on the same horizontal line. A set of bolts 25 are threaded inside the two U-shaped soft rubber sleeves 23. Both sets of bolts 25 are fitted to the outer surface of the printed circuit board body 12. When the two curved blocks 16 are engaged in the slots 18, the rectangular limiting seat 13 is pressed inward and slids, which will compress the second spring 21 and retract it. The retractable rectangular limiting seat 13 adapts to different degrees of curvature of the printed circuit board body 12, and the U-shaped soft rubber sleeve 23 is fitted onto the surface of the printed circuit board body 12. At this time, the two curved angle limiting blocks 24 and the printed circuit board body 12 are in a flat state. When the printed circuit board body 12 bends, the degree of bending will cause the two curved angle limiting blocks 24 to move closer to each other. When the two curved angle limiting blocks 24 are in contact, they will limit the printed circuit board body 12 and prevent it from bending further. The two curved angle limiting blocks 24 limit the maximum degree of bending of the printed circuit board body 12 and prevent the printed circuit board body 12 from being damaged.

[0032] A cover 26 is fixedly connected to the upper end of the storage box 11, and a wiring port 27 is fixedly connected to the outer surface of the storage box 11. The printed circuit board body 12 is shielded and protected by the cover 26, and the wiring port 27 installed on the outside of the storage box 11 is used for wiring so that the printed circuit board body 12 can be connected to electronic components.

[0033] To address the problems existing in the prior art, this utility model provides a PCB board with a bending function. Pulling the mounting block 14 can cause the printed circuit board body 12 to bend. When the printed circuit board body 12 is bent to the required installation size, the rectangular limiting seat 13 is released and slides out. At the same time, the two pressing rods 15 are released, the first spring 17 returns to its deformation, and pushes the two arc-shaped locking blocks 16 to slide against the inner surface of the rectangular limiting seat 13. The arc-shaped locking blocks 16 are engaged in the slots 18 opened inside the rectangular limiting seat 13, thereby fixing the bent printed circuit board body 12 and keeping it in the required bending state. Through the engagement of the arc-shaped locking blocks 16 and the slots 18 inside the rectangular limiting seat 13, the printed circuit board body 12 can be accurately fixed in the required bending state. Moreover, the fast fixing operation can be achieved by pushing the pressing rods 15 and the rectangular limiting seat 13, avoiding the unstable operation of workers pressing to maintain the current position while turning the screw, which greatly shortens the installation time and improves the efficiency of the production or assembly process.

[0034] Storage box 11: As the external carrier of the entire device, it provides a space for the printed circuit board body 12 and protects it from the direct influence of the external environment.

[0035] Printed circuit board body 12: It has a bending function and can integrate multiple circuit functions in a limited space. For example, in smart home devices, it can simultaneously accommodate control, sensing and wireless communication circuits, reduce the size of the device and enhance product competitiveness.

[0036] Rectangular limiting seat 13: When it is necessary to bend the printed circuit board body 12, manually press the rectangular limiting seat 13 inward. It can slide in the support plate 19 and squeeze the second spring 21 to retract, thereby making room for bending the printed circuit board body 12.

[0037] Mounting block 14: It is fixedly connected to the outer surface of the printed circuit board body 12, providing a mounting base for the pressing rod 15 and the arc-shaped locking block 16, and together with the pressing rod 15, the arc-shaped locking block 16 and the first spring 17, it forms a locking mechanism.

[0038] Pressing lever 15: When pressed inward, it drives the arc-shaped locking block 16 fixedly connected to it to slide inward, compressing the first spring 17 to contract, so that the arc-shaped locking block 16 is disengaged from the rectangular limiting seat 13, so as to perform a bending operation on the printed circuit board body 12.

[0039] Arc-shaped locking block 16: Under the action of the pressing rod 15, it slides inward to squeeze the first spring 17. When the pressing rod 15 is released, it slides against the inner surface of the rectangular limiting seat 13 under the action of the first spring 17 and is locked in the slot 18 opened inside the rectangular limiting seat 13. It closely cooperates with the rectangular limiting seat 13 to accurately fix the bending state of the printed circuit board body 12 and prevent it from changing its bending state during use.

[0040] First spring 17: When the pressing rod 15 is released, it releases elastic potential energy, pushes the arc-shaped locking block 16 to slide against the inner surface of the rectangular limiting seat 13, thereby fixing the printed circuit board body 12 in a bent state and providing reset power for the locking mechanism.

[0041] Slot 18: It is formed inside the rectangular limiting seat 13 and is adapted to the curved surface block 16. When the curved surface block 16 slides under the action of the first spring 17, it is inserted into the slot 18. Together with the curved surface block 16, it precisely limits the bending angle and shape of the printed circuit board body 12, ensuring that the printed circuit board body 12 remains stable in the required bending state.

[0042] Support plate 19: It is fixedly connected inside the storage box 11 and provides a sliding track for the rectangular limiting seat 13 so that it can slide smoothly inside; it cooperates with the rectangular limiting seat 13 and the second spring 21. When the rectangular limiting seat 13 is pressed, the support plate 19 bears the reaction force of the rectangular limiting seat 13 pressing the second spring 21, ensuring the stability of the entire limiting mechanism inside the storage box 11.

[0043] The second spring 21 is fixedly connected inside the support plate 19 and connected to the outer surface of the slot 18. When the rectangular limiting seat 13 is pressed inward, it is compressed and contracts, storing elastic potential energy. When the rectangular limiting seat 13 is released, it releases the elastic potential energy, pushes the rectangular limiting seat 13 to slide out, so that the slot 18 and the arc-shaped locking block 16 can be accurately docked. This provides power for the reset of the rectangular limiting seat 13 and its cooperation with the arc-shaped locking block 16, thereby achieving precise fixation of the printed circuit board body 12 in a bent state.

[0044] Rubber pads 22: are fixed on the outer surfaces of the two pressing rods 15 respectively, increasing the friction between the operator's fingers and the pressing rods 15, making the pressing operation more comfortable and easier to apply force, facilitating the operator's operation of the pressing rods 15, thereby controlling the movement of the arc-shaped locking block 16, and realizing the bending and fixing operation of the printed circuit board body 12.

[0045] U-shaped soft rubber sleeve 23: It has its own soft properties and can adapt to the bending changes of the printed circuit board body 12. At the same time, the arc angle limiting block 24 fixedly connected to its lower end can limit the maximum bending degree of the printed circuit board body 12 and protect the printed circuit board body 12 from being damaged due to excessive bending.

[0046] Arc angle limiting block 24: It is fixed to the lower end of the two U-shaped soft rubber sleeves 23 and is on the same horizontal line. When the printed circuit board body 12 is bent, it drives the two arc angle limiting blocks 24 to move closer to each other. When the two are in contact, it limits the further bending of the printed circuit board body 12, avoids damage to the printed circuit board body 12 due to excessive bending, ensures that it is used within a safe bending range, and cooperates with the U-shaped soft rubber sleeves 23 to protect the printed circuit board body 12.

[0047] Bolt 25: Threaded connection inside the U-shaped soft rubber sleeve 23. Rotating the bolt 25 can make it fit tightly against the outer surface of the printed circuit board body 12, thereby firmly fixing the U-shaped soft rubber sleeve 23 to the printed circuit board body 12, ensuring that the U-shaped soft rubber sleeve 23 can stably follow the bending process of the printed circuit board body 12, and allowing the arc angle limiting block 24 to play the role of limiting the maximum bending degree of the printed circuit board body 12.

[0048] Box lid 26: Fixed to the upper end of the storage box 11, together with the storage box 11, it shields and protects the printed circuit board body 12, preventing it from being damaged by external physical forces such as collisions and scratches, while blocking dust, moisture and other pollutants from entering the storage box 11, thus protecting the performance and service life of the printed circuit board body 12.

[0049] Wiring port 27: Fixed on the outer surface of the storage box 11, it serves as an interface for connecting the printed circuit board body 12 with other electronic components, enabling circuit connectivity and allowing the printed circuit board body 12 to be connected to the electronic equipment system and perform its circuit functions.

[0050] Working principle:

[0051] The first step is that the printed circuit board body 12 is composed of a copper foil circuit layer, an insulating layer, and a cover layer. The insulating layer and cover layer materials themselves have good bendability. During the design and manufacturing process, the copper foil circuit can be bent with the insulation layer by optimizing the circuit layout and using thinner copper foil, while ensuring stable transmission of electrical signals. For example, designing the copper foil circuit into a flexible structure such as a serpentine or grid shape can effectively disperse the stress generated during bending and reduce the risk of circuit breakage. The printed circuit board body 12 has bending function and can integrate more functions in a limited space. For example, in smart home devices, the curved printed circuit board body 12 can simultaneously accommodate control circuits, sensor circuits, and wireless communication circuits, achieving a high degree of integration of multiple functions, reducing device size, lowering costs, and enhancing product competitiveness. When installing the printed circuit board body 12, it is placed inside the storage box 11, with one end of the body fixed inside the box 11 by a screw, providing basic support for subsequent operations. The cover 26 is fixed to the upper end of the storage box 11, providing shielding and protection for the printed circuit board body 12, preventing it from being damaged by external physical forces and contamination such as dust. The wiring port 27 is fixed to the outer surface of the storage box 11, used to connect the printed circuit board body 12 with other electronic components to achieve circuit connectivity.

[0052] The second step involves manually pressing the rectangular limiting seat 13 inwards when bending the printed circuit board body 12. This allows the rectangular limiting seat 13 to slide inside the support plate 19. Simultaneously, the rectangular limiting seat 13 compresses the second spring 21, creating space for the bending of the printed circuit board body 12. At the same time, the operator presses the two pressing rods 15 on the mounting block 14 inwards. These rods cause the arc-shaped locking blocks 16, which are fixedly connected to them, to slide inwards, compressing the first spring 17. Pulling the mounting block 14 then bends the printed circuit board body 12. When the printed circuit board body 12 is bent to the required installation size, the rectangular limiting seat 13 is released, allowing it to slide out. Simultaneously, the two pressing rods 15 are released, restoring the first spring 17's deformation and pushing the two arc-shaped locking blocks 16 to slide against the inner surface of the rectangular limiting seat 13. The curved locking block 16 engages with the slot 18 inside the rectangular limiting seat 13, thereby fixing the bent printed circuit board body 12 and keeping it in the required bending state. Two U-shaped soft rubber sleeves 23 are fitted onto the outer surface of the printed circuit board body 12. By rotating two sets of bolts 25, they are made to fit against the outer surface of the printed circuit board body 12, fixing the U-shaped soft rubber sleeves 23 onto the printed circuit board body 12. The U-shaped soft rubber sleeves 23 themselves have the softness to adapt to the bending changes of the printed circuit board body 12. When the printed circuit board body 12 bends, it will drive the two curved angle limiting blocks 24 fixedly connected at the lower end to move closer to each other. When the two curved angle limiting blocks 24 fit together, they restrict the further bending of the printed circuit board body 12, thereby preventing the printed circuit board body 12 from being damaged due to excessive bending and ensuring that it is used within a safe bending range.

[0053] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
