Detailed Implementation
[0023] 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.
[0024] Example 1: Please refer to Figures 1-4 A PCB circuit board with a protective structure includes a circuit board body 1. A first protective shell 2 and a second protective shell 3 are respectively installed on the top and bottom of the circuit board body 1. The first protective shell 2 and the second protective shell 3 cover and protect the top and bottom of the circuit board body 1, respectively. The entire structure is tightly fixed together by screws 5. The screw fixing method not only ensures the stability of the entire structure, but also facilitates disassembly, maintenance or replacement of parts. In addition, a certain space is left between the first protective shell 2 and the second protective shell 3 and the circuit board body 1 to facilitate ventilation and heat dissipation. The outer surface of the first protective shell 2 and the second protective shell 3 is equipped with rubber buffer blocks 4 to provide additional impact protection. Strong magnets 12 are embedded in the bottom of the first protective shell 2 and the top sides of the second protective shell 3. The strong magnets 12 attract each other magnetically to enhance the tightness and stability between the protective shells.
[0025] The first protective shell 2 and the second protective shell 3 set at the top and bottom of the circuit board body 1 respectively provide physical protection for the circuit board. In the event of an accident such as a collision or drop during daily use or transportation, the protective shell can absorb and disperse the impact force, thereby reducing direct damage to the electronic components inside the circuit board. In addition, the protective effect is further enhanced by adding rubber buffer blocks 4. Through their elastic properties, they can provide additional cushioning in the event of a collision, reducing the impact of external impacts on the circuit board.
[0026] Example 2: Based on Example 1, please refer to... Figure 2 and Figure 5 Each of the first protective shell 2 and the second protective shell 3 has a protective side cover 6 between its left and right sides. Each protective side cover 6 has a first locking block 7 symmetrically distributed vertically. The first protective shell 2 and the second protective shell 3 have two first locking slots that are adapted to the first locking block 7 at corresponding positions on their left and right sides. By locking the first locking block 7 into the corresponding first locking slot, the protective side cover 6 can be firmly fixed. In addition, the first protective shell 2 and the second protective shell 3 have locking balls 14 on their front and rear sides. The protective side cover 6 has locking holes that are adapted to the locking balls 14 on its front and rear sides. By locking the locking balls 14 into the locking holes, the connection between the connecting frame and the protective shell can be enhanced, and the stability can be improved. A dustproof mesh 8 is embedded in the protective side cover 6 to prevent dust from entering the circuit board area. A pull rod 11 is fixed to the front of the protective side cover 6 to facilitate the operation of the protective side cover 6 for disassembly and assembly by the staff.
[0027] After the first protective shell 2 and the second protective shell 3 are installed, the protective side cover 6 is fixedly installed by engaging the first locking block 7 on it with the first locking groove on the side of the first protective shell 2 and the second protective shell 3. The protective side cover 6 protects the left and right sides of the circuit board body 1, providing better overall protection for the PCB circuit board and enhancing the stability of the entire protective structure. In addition, the dustproof mesh 8 inside the protective side cover 6 effectively prevents external dust from entering the circuit board body 1 while ensuring heat dissipation, reducing the risk of overheating or other electrical failures caused by dust accumulation, thereby improving the reliability and service life of the equipment.
[0028] Please see Figure 6 The first protective shell 2 and the second protective shell 3 each have three slots 301 on their surfaces. Each slot 301 has a heat-conducting sheet 10 inserted inside. The heat-conducting sheet 10 is made of a metal material with high thermal conductivity so as to effectively conduct the heat of the circuit board body 1 to the protective shell. The left and right ends of the heat-conducting sheet 10 are provided with second locking blocks 9. The corresponding positions on the surfaces of the first protective shell 2 and the second protective shell 3 are provided with second locking slots that are adapted to the second locking blocks 9. The second locking blocks 9 are inserted into the corresponding second locking slots to fix the heat-conducting sheet 10. The surface of the second locking blocks 9 is provided with a pull rope 13 so that the staff can pull the second locking blocks 9 to disassemble them.
[0029] By inserting the heat-conducting plate 10 into the slot 301 on the surface of the first protective shell 2 and the second protective shell 3, it directly contacts and absorbs the heat generated by the circuit board body 1 during operation. Since the heat-conducting plate 10 has good thermal conductivity, it can effectively dissipate heat to the outside, improve the overall heat dissipation performance, effectively extend the service life of the circuit board body 1 and ensure its operational stability.
[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
