Description

Technical Field

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

[0002] As a core component of electronic devices, the reliability of circuit boards directly affects the performance and lifespan of the equipment. With the trend of miniaturization and integration of electronic devices, circuit boards face challenges from complex mechanical environments such as high-frequency bending and vibration shock. In scenarios such as automotive electronics and industrial control, vibration and shock environments can easily lead to circuit board deformation, causing problems such as solder joint cracking and circuit breakage.

[0003] In existing technologies, traditional circuit boards lack effective deformation-resistant structural designs. When subjected to external impacts or bending forces, the circuit board itself is prone to severe deformation, leading to cracking of surface solder joints, breakage of internal circuits, and even failure of the entire circuit board. This defect not only reduces the service life of the equipment but also increases after-sales maintenance costs.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the circuit board body is subjected to impact, it undergoes severe deformation, causing the solder joints on the surface of the circuit board body to crack, thereby causing the circuit board body to be unable to be used normally; therefore, in order to solve the above problems, a circuit board with bending-resistant reinforcing ribs is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the circuit board body undergoes severe deformation when subjected to impact, leading to cracking of the solder joints on the surface of the circuit board body and rendering the circuit board body unusable. Therefore, this invention proposes a circuit board with bending-resistant reinforcing ribs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a circuit board with anti-bending reinforcing ribs, comprising a circuit board body, a first fixing plate slidably connected to the surface of the circuit board body, a reinforcing rib body fixedly connected to the surface of the first fixing plate, a second fixing plate fixedly connected to the surface of the reinforcing rib body, a U-shaped frame slidably connected to the surface of the circuit board body, a baffle slidably connected to the surface of the U-shaped frame, fixing rods fixedly connected to both sides of the U-shaped frame, an L-shaped plate slidably connected to the arc surface of the fixing rods, a limiting rod fixedly connected to the surface of the L-shaped plate, a limiting block fixedly connected to one end of the limiting rod, and two limiting grooves formed on the surface of the baffle.

[0007] The effect achieved by the above components is to increase the bending resistance of the circuit board body, avoid the circuit board body from undergoing severe deformation when subjected to impact, which would cause the solder joints on the surface of the circuit board body to crack, thereby preventing the circuit board body from being used normally and improving the practicality of the equipment.

[0008] Preferably, a groove is provided at the end of the fixing rod away from the U-shaped frame, and a circular block is fixedly connected to the surface of the groove of the fixing rod.

[0009] The effect achieved by the above components is that the circular block can restrict the movement of the L-shaped plate, preventing the L-shaped plate from slipping off the arc surface of the fixing rod when the operator pulls it with excessive force.

[0010] Preferably, two rotating rods are fixedly connected to the surface of the U-shaped frame, a rotating plate is rotatably connected to the arc surface of the rotating rods, an insert rod is fixedly connected to the surface of the rotating plate, and a slot is provided on the surface of the L-shaped plate.

[0011] The effect achieved by the above components is to restrict the movement of the L-shaped plate, thereby facilitating the movement of the baffle by the staff.

[0012] Preferably, the surface of the U-shaped frame is fixedly connected to two first blocking blocks, and the surface of the U-shaped frame is fixedly connected to two second blocking blocks.

[0013] The effect achieved by the above components is to fix the rotating plate in place, making it convenient for workers to quickly rotate the rotating plate to the appropriate position.

[0014] Preferably, a fixing block is fixedly connected to one end of the rotating rod, and a torsion spring is sleeved on the arc surface of the rotating rod, with the two ends of the torsion spring being fixed to the fixing block and the rotating plate, respectively.

[0015] The effect achieved by the above components is that the torque of the torsion spring automatically rotates the rotating plate back to its original position, reducing the number of operating steps for the staff and making it easier for them to proceed to the next step of the operation more quickly.

[0016] Preferably, the arc surface of the fixing rod is fitted with a spring, and the two ends of the spring are fixedly connected to the U-shaped frame and the L-shaped plate, respectively.

[0017] The effect achieved by the above components is that the spring's rebound force automatically moves the limit block back to its original position, while also restricting the movement of the limit block and improving the stability of the limit block when fixing the baffle.

[0018] In summary, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model achieves the effect of increasing the bending resistance of the circuit board body, avoiding the circuit board body from undergoing severe deformation when subjected to impact, which would cause the solder joints on the surface of the circuit board body to crack, thereby preventing the circuit board body from being used normally and improving the practicality of the equipment.

Detailed Implementation

[0027] Reference Figures 1-6As shown, this utility model provides a technical solution: a circuit board with anti-bending reinforcing ribs, including a circuit board body 1, a first fixing plate 2 slidably connected to the surface of the circuit board body 1, a reinforcing rib body 3 fixedly connected to the surface of the first fixing plate 2, a second fixing plate 4 fixedly connected to the surface of the reinforcing rib body 3, a U-shaped frame 5 slidably connected to the surface of the circuit board body 1, a baffle 6 slidably connected to the surface of the U-shaped frame 5, fixing rods 7 fixedly connected to both sides of the U-shaped frame 5, an L-shaped plate 8 slidably connected to the arc surface of the fixing rods 7, a limiting rod 9 fixedly connected to the surface of the L-shaped plate 8, a limiting block 10 fixedly connected to one end of the limiting rod 9, and two limiting grooves formed on the surface of the baffle 6, thereby increasing the anti-bending ability of the circuit board body 1 and preventing bending. When the circuit board body 1 is subjected to impact, it undergoes severe deformation, causing the solder joints on the surface of the circuit board body 1 to crack, thus rendering the circuit board body 1 unusable. This improves the practicality of the equipment. A groove is provided at the end of the fixing rod 7 away from the U-shaped frame 5. A circular block 19 is fixedly connected to the surface of the groove of the fixing rod 7. When the operator needs to remove the reinforcing ribs on the surface of the circuit board body 1, the L-shaped plate 8 is pulled. The L-shaped plate 8 moves the limiting rod 9, which in turn moves the limiting block 10. When the surface of the L-shaped plate 8 contacts the circular block 19, the limiting block 10 completely disengages from the surface of the limiting groove of the baffle 6, releasing the baffle 6 from its fixation. The baffle 6 is then moved. When the baffle 6 completely disengages from the surface of the U-shaped frame 5, the operator can remove the reinforcing ribs. The reinforcing rib body 3 moves the second fixing plate 4, which in turn moves the reinforcing rib body 3, which in turn moves the first fixing plate 2. When the first fixing plate 2 is completely detached from the surface of the circuit board body 1, the disassembly is complete. After the reinforcing rib body 3 is returned to its original position, the baffle 6 is also returned to its original position. The L-shaped plate 8 is then pushed to move the limiting rod 9, which in turn moves the limiting block 10 until the limiting block 10 moves to the surface of the limiting groove of the baffle 6. The circular block 19 effectively restricts the movement of the L-shaped plate 8, preventing the L-shaped plate 8 from slipping off the arc surface of the fixing rod 7 due to excessive force applied when pulling it. Two rotating rods 11 are fixedly connected to the surface of the U-shaped frame 5. A rotating plate 12 is rotatably connected to the arc surface of the L-shaped plate 8. A rod 13 is fixedly connected to the surface of the rotating plate 12. A slot is provided on the surface of the L-shaped plate 8. When the operator needs to open the baffle 6, pulling the L-shaped plate 8 moves the limiting rod 9, which in turn moves the limiting block 10. When the surface of the L-shaped plate 8 contacts the circular block 19, the limiting block 10 releases its fixation to the baffle 6. The rotating plate 12 is then rotated. When the rotating plate 12 reaches the appropriate position, the L-shaped plate 8 is positioned directly in front of the rod 13. The L-shaped plate 8 is pushed until the rod 13 is inserted into the slot of the L-shaped plate 8. At this point, the operator can move the baffle 6. After the operator returns the baffle 6 to its original position, the L-shaped plate 8 is moved. When the L-shaped plate 8 reaches the appropriate position, the rotating plate 12 is rotated.The rotating plate 12 drives the insert rod 13 to rotate. When the insert rod 13 no longer obstructs the movement of the L-shaped plate 8, the operator can move the limiting block 10 to the surface of the limiting groove of the baffle 6, thus achieving the effect of restricting the movement of the L-shaped plate 8 and facilitating the operator's movement of the baffle 6. Two first blocking blocks 14 and two second blocking blocks 15 are fixedly connected to the surface of the U-shaped frame 5. When the operator needs to use the rotating plate 12 to fix the L-shaped plate 8, the L-shaped plate 8 is rotated to a suitable position, and the rotating plate 12 is rotated. Plate 12 drives the insertion rod 13 to move. When the surface of rotating plate 12 contacts the first blocking block 14, rotating plate 12 stops moving. At this time, rotating plate 12 rotates to a suitable position, and insertion rod 13 can restrict the movement of L-shaped plate 8, achieving the effect of fixing rotating plate 12, making it convenient for workers to quickly rotate rotating plate 12 to a suitable position. One end of rotating rod 11 is fixedly connected to fixing block 16, and the arc surface of rotating rod 11 is fitted with torsion spring 17. The two ends of torsion spring 17 are fixed to fixing block 16 and rotating plate 12 respectively. When workers need to... To return the rotating plate 12 to its original position, the moving L-shaped plate 8 drives the limiting rod 9 to move, which in turn drives the limiting block 10 to move. When the L-shaped plate 8 moves to the appropriate position, the torque of the torsion spring 17 drives the rotating plate 12 to rotate, which in turn drives the insert rod 13 to move until the rotating plate 12 contacts the surface of the second blocking block 15. The torque of the torsion spring 17 achieves the effect of automatically returning the rotating plate 12 to its original position, reducing the number of steps required by the operator and facilitating faster execution of the next step. The arc surface of the fixing rod 7 is fitted with a spring 1. 8. The two ends of spring 18 are fixedly connected to U-shaped frame 5 and L-shaped plate 8 respectively. When rotating plate 12 contacts the surface of second blocking block 15, L-shaped plate 8 is released. The rebound force of spring 18 drives L-shaped plate 8 to move, L-shaped plate 8 drives limiting rod 9 to move, and limiting rod 9 drives limiting block 10 to move until limiting block 10 moves to the surface of limiting groove of baffle 6. The rebound force of spring 18 achieves the effect of automatically moving limiting block 10 back to its original position, while also restricting the movement of limiting block 10, thus improving the stability of limiting block 10 when fixing baffle 6.

[0028] Working principle: When the operator needs to remove the reinforcing ribs on the surface of the circuit board body 1, pulling the L-shaped plate 8 stretches the spring 18, causing the L-shaped plate 8 to move the limiting rod 9, which in turn moves the limiting block 10. When the surface of the L-shaped plate 8 contacts the circular block 19, the limiting block 10 completely disengages from the surface of the limiting groove of the baffle 6, releasing the baffle 6 from its fixation. The rotating plate 12 is then rotated, causing the insertion rod 13 to move. When the surface of the rotating plate 12 contacts the first blocking block 14, the rotating plate 12 stops rotating. At this point, the rotating plate 12 has rotated to the appropriate position, with the slot of the L-shaped plate 8 directly in front of the insertion rod 13. The L-shaped plate 8 is pushed until the insertion rod 13 is inserted into the surface of the slot of the L-shaped plate 8. The operator can then move the baffle 6. When the baffle 6 completely disengages from the surface of the U-shaped frame 5, the operator can remove the reinforcing rib body 3 and move the second fixing plate 4, which in turn moves the reinforcing rib body 3. The reinforcing rib body 3 moves the first fixing plate 2. When the first fixing plate 2 is completely detached from the surface of the circuit board body 1, the disassembly is complete. After the reinforcing rib body 3 is put back in its original position, the baffle 6 is put back in its original position, and the L-shaped plate 8 is moved. When the L-shaped plate 8 moves to the appropriate position, the torque of the torsion spring 17 drives the rotating plate 12 to rotate. The rotating plate 12 drives the insertion rod 13 to move until the rotating plate 12 contacts the surface of the second blocking block 15. The L-shaped plate 8 is released, and the rebound force of the spring 18 drives the L-shaped plate 8 to move. The L-shaped plate 8 drives the limiting rod 9 to move, and the limiting rod 9 drives the limiting block 10 to move until the limiting block 10 moves to the surface of the limiting groove of the baffle 6. At this time, the effect of increasing the bending resistance of the circuit board body 1 is achieved, avoiding the circuit board body 1 from undergoing severe deformation when subjected to impact, which would cause the solder joints on the surface of the circuit board body 1 to crack, thus causing the circuit board body 1 to be unable to be used normally.
