[0002] With the rapid development of the automotive industry, especially new energy vehicles and intelligent connected vehicles, the level of vehicle electrification and intelligence is constantly improving. A large number of electronic control units (ECUs), sensors and actuators are deployed in the chassis and bottom area of ​​the vehicle body to realize various functions such as battery thermal management, chassis domain control, environmental perception and intelligent lighting. In order to protect these critical electronic devices from mechanical damage such as road gravel impact, mud and water erosion and bottoming out, vehicle protection plates (such as chassis protection plates and battery underbody protection plates) have become indispensable components. In order to achieve functional integration and localized control, the relevant control circuit boards are directly integrated on or inside the protection plate, which has become an efficient and compact system layout solution.

[0003] Existing circuit boards are usually integrated into vehicle protection boards using bolts. During vehicle operation, multi-frequency vibrations from the road surface and engine are continuously transmitted, which can easily be transmitted to the circuit board, causing fatigue cracking of component solder joints or cracking damage to the circuit board. Therefore, we need to propose a vibration- and shock-resistant rigid circuit board for vehicle protection boards. Utility Model Content

[0004] The purpose of this invention is to provide a vibration- and shock-resistant rigid circuit board for vehicle protection panels. By setting a protective structure to protect the circuit board, the protective structure mitigates the transmitted vibration, reduces the impact of vibration on the circuit board, and thus ensures the service life of the circuit board. At the same time, the protective structure can support the edges and corners of the circuit board to prevent deformation caused by vibration, thereby improving the vibration resistance and impact resistance of the circuit board, and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration- and shock-resistant rigid circuit board for vehicle protection boards, comprising:

[0006] The circuit board body and the protective structure installed on the outside of the circuit board body protect the circuit board from vibration and impact.

[0007] The protective structure includes, from bottom to top, a lower protective frame, multiple sets of docking components, multiple sets of reinforcing components, two sets of vibration-resistant components, and an upper protective frame.

The circuit board body is located between the two sets of vibration-resistant components, and the outer side of the circuit board body is defined by the multiple sets of docking components and multiple sets of reinforcing components.

The lower surface of the protective lower frame is integrally formed with multiple sets of bottom beams, and the two sets of buffer pads located in the lower layer are both bonded to the upper surface of the protective lower frame.

[0010] Preferably, the lower surface of the protective upper frame has multiple sets of second holes, and the upper surface of the protective upper frame has multiple sets of reinforcing beams integrally formed thereon, with the upper two sets of buffer pads being bonded to the lower surface of the protective upper frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a vibration and shock resistant rigid circuit board for vehicle protection board, including a circuit board body 1 and a protective structure installed on the outside of the circuit board body 1, which protects the circuit board from vibration and shock.

[0023] The protective structure includes, from bottom to top, a lower protective frame 2, multiple sets of docking components 5, multiple sets of reinforcing components 6, two sets of vibration-resistant components 7, and a upper protective frame 4. The multiple sets of docking components 5 and multiple sets of reinforcing components 6 are both located on the outside of the two sets of vibration-resistant components 7. The two sets of vibration-resistant components 7 are respectively located on the opposite side of the lower protective frame 2 and the upper protective frame 4. The circuit board body 1 is located between the two sets of vibration-resistant components 7, and the outside of the circuit board body 1 is limited by the multiple sets of docking components 5 and multiple sets of reinforcing components 6.

[0024] Both sets of vibration-resistant components 7 include a protective base plate 71. Both sides of the protective base plate 71 are integrally formed with connecting beams 72. Both sides of the connecting beams 72 adjacent to the protective base plate 71 are provided with buffer pads 73. Multiple sets of rubber pillars 74 are fixedly connected to the side of the protective base plate 71 opposite to the circuit board.

[0025] In this embodiment, the protective substrate 71 provides shielding protection above and below the circuit board body 1, while the integrally formed connecting beam 72 enhances the structural rigidity of the protective substrate 71, preventing the vibration-resistant component 7 from deforming due to vibration. At the same time, the connecting beam 72 is provided with a buffer pad 73, which can directly absorb the lateral impact force generated during vehicle vibration, preventing the lateral vibration from being directly transmitted to the circuit board body 1. In addition, multiple sets of rubber pillars 74 can absorb vertical vibration energy (such as the up-and-down impact when the vehicle is bumping) through their own elastic deformation, preventing the electronic components on the circuit board body 1 from falling off or being damaged due to vertical stress, thereby improving the vibration resistance of the circuit board body 1.

[0026] The upper surface of the protective lower frame 2 has multiple sets of first holes 21, and the multiple sets of first holes 21 are equally spaced. The lower surface of the protective lower frame 2 has multiple sets of bottom beams integrally formed, and the two sets of buffer pads 73 located in the lower layer are both bonded to the upper surface of the protective lower frame 2.

[0027] Preferably, multiple sets of bottom beams can enhance the bending and deformation resistance of the lower frame, prevent the lower frame from deforming due to long-term vehicle vibration, and ensure the stability of the underlying foundation frame. The buffer pads 73 of the lower vibration-resistant component 7 are directly bonded to the upper surface of the protective lower frame 2, realizing a flexible connection between the vibration-resistant component 7 and the lower frame. This ensures a stable connection without affecting the elastic buffering effect of the buffer pads 73. At the same time, multiple sets of first holes 21 with equal spacing can reduce the overall weight of the protective lower frame 2 (to meet the vehicle's lightweight requirements) and enhance air circulation under the circuit board body 1, assisting in heat dissipation of the circuit board body 1 and preventing high temperature from affecting component performance.

[0028] The lower surface of the protective upper frame 4 has multiple sets of second holes 41, and the upper surface of the protective upper frame 4 has multiple sets of reinforcing beams 42 integrally formed. The two sets of buffer pads 73 located on the upper layer are both bonded to the lower surface of the protective upper frame 4.

[0029] Similarly, multiple sets of reinforcing beams 42 can directly resist possible external impacts from above (such as the collision force transmitted by the vehicle protection plate), preventing the impact from acting directly on the circuit board body 1. The upper buffer pad 73 is bonded to the lower surface of the protective upper frame 4, forming a corresponding horizontal buffer structure with the lower buffer pad 73, ensuring that the horizontal vibrations on the upper and lower sides of the circuit board body 1 can be absorbed, with no blind spots in protection. Multiple sets of second holes 41 echo the first hole 21 of the lower frame, further optimizing the overall weight and providing a heat dissipation channel for the upper part of the circuit board body 1, improving heat dissipation efficiency.

[0030] Each of the multiple docking components 5 includes a lower fixing block 51 and an upper fixing block 52. The lower fixing block 51 is fixedly connected to the upper surface of the lower protective frame 2, and the upper fixing block 52 is fixedly connected to the lower surface of the upper protective frame 4. A square shaft 53 is fixedly connected to the lower surface of the upper fixing block 52, and a square hole 54 for the square shaft 53 to be inserted is provided on the lower surface of the lower fixing block 51.

[0031] Preferably, the square shaft 53 is inserted into the square hole 54, which can prevent relative rotational misalignment between the upper protective frame 4 and the lower protective frame 2 during installation, ensure the positional accuracy during the assembly of the protective structure, reduce protective failure caused by assembly deviation, and improve the ease of installation of the upper protective frame 4 and the lower protective frame 2.

[0032] Each of the multiple sets of reinforcement components 6 includes two sets of support seats 61 and fastening bolts 63. The two sets of support seats 61 are respectively fixedly connected to the opposite side of the lower protective frame 2 and the upper protective frame 4. The lower end of the fastening bolts 63 passes through the upper protective frame 4 and the upper support seat 61 in sequence and is bolted to the lower support seat 61. Each set of support seats 61 is fixedly connected to a limit block 62 on the side opposite to the circuit board body 1.

[0033] In a further preferred embodiment, the fastening bolt 63 passes through the upper protective frame 4 and the upper support seat 61 and is bolted to the lower support seat 61, which can rigidly lock the upper protective frame 4 and the lower protective frame 2, thereby improving the overall rigidity of the protective structure and preventing the protective structure from loosening under strong vibration. The limiting side block 62 can form a physical block in the vertical direction from the side of the circuit board body 1, preventing the circuit board body 1 from shifting laterally (such as sliding left and right) during vibration and reducing vertical vibration.

[0034] It also includes two sets of mounting bases 3, and the two sets of mounting bases 3 are fixedly connected to both sides of the protective lower frame 2. Each of the two sets of mounting bases 3 has an integrally formed reinforcing connecting beam 31 located on the lower surface of the protective lower frame 2 on the opposite side.

[0035] Secondly, the two sets of mounting bases 3 provide the overall mounting foundation for the circuit board body 1 and the vehicle protection plate, ensuring that the circuit board body 1 can be stably assembled into the designated position on the vehicle, avoiding installation deviation. Furthermore, the reinforcing connecting beam 31 is integrally formed between the mounting base 3 and the lower surface of the protective lower frame 2, which can disperse the stress transmitted by the mounting base 3 (such as the stress at the connection between the mounting base 3 and the protective lower frame 2 when the vehicle vibrates), preventing the base and the protective lower frame 2 from breaking due to stress concentration.

[0036] In use, place the circuit board body 1 on top of the vibration-resistant component 7 on the lower protective frame 2, so that the circuit board body 1 is aligned with the limiting side plate on the lower support 61 and the buffer pad 73 on the upper surface of the lower connecting beam 72. Then, place the upper protective frame 4 on top of the lower protective frame 2, and complete the docking assembly by inserting the square shaft 53 into the square hole 54. Use multiple sets of fastening bolts 63 to connect and tighten the two sets of support 61. During this process, the buffer pad 73 will be subjected to a certain amount of compression. At the same time, the side of the limiting side plate that contacts the circuit board body 1 is provided with rubber. The pads further prevent damage to the circuit board from rigid clamping. When the vehicle vibrates, the rubber pillars 74 of the vibration-resistant component 7 absorb vertical impact energy through elastic deformation, while the buffer pads 73 absorb lateral vibration energy, preventing vibration from being directly transmitted to the circuit board body 1, thereby reducing the impact of vibration. The entire protective structure (including the circuit board body 1) is securely assembled to the vehicle protection plate by two sets of mounting bases 3, and the reinforced connecting beams 31 disperse the installation stress, ensuring the stability of the connection between the overall structure and the vehicle, and preventing the installation parts from loosening due to vibration.
