[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figure 1-6 , the present invention provides a technical solution: a circuit board with an antistatic coating, including: a circuit board body 2, a bearing component 1 for fixing and bearing the circuit board body 2 is provided at the bottom of the circuit board body 2, and a buffer component 3 for buffering and protecting the circuit board body 2 is provided at the bottom of the bearing component 1.
[0024] The buffer component 3 includes: a second sliding rod 37, the outside of the second sliding rod 37 is slidably inserted into the inside of the slide block 38, both ends of the second sliding rod 37 are fixedly connected to one side of the connecting block 35, the other side of the connecting block 35 is fixedly connected to both ends of the first sliding rod 33, the outside of the first sliding rod 33 is slidably inserted into the inside of both ends of the moving strip block 39, and both ends of the moving strip block 39 are rotatably connected to the side of the top end of the diagonal strut 34. The side of the bottom end of the diagonal strut 34 is rotatably connected to the side of the mounting plate 32.
[0025] Both ends of the outside of the first sliding rod 33 are inserted into the inner ring of the first buffer spring 31. One end of the first buffer spring 31 is fixedly connected to one side of the connecting block 35, and the other end of the first buffer spring 31 is fixedly connected to the side of the moving strip block 39.
[0026] Further, when a collision or shock occurs and the circuit board body 2 and the bearing plate 13 move up and down, the bearing plate 13 pushes the slide block 38 downward. The slide block 38 pushes the connecting block 35 and the first sliding rod 33 downward through the second sliding rod 37. The first sliding rod 33 drives the moving strip block 39 to move downward. While the moving strip block 39 moves downward, the diagonal strut 34 pushes the moving strip block 39 toward the connecting block 35, causing the moving strip block 39 to compress the first buffer spring 31. Then, the first buffer spring 31 plays a buffering role.
[0027] Furthermore, when the supporting plate 13 moves axially along the slide bar 1 33 , the supporting plate 13 will drive the connecting block 35 to move axially along the slide bar 1 33 through the slider 38 and the slide bar 2 37 , so that the connecting block 35 causes stretching or compression on the buffer spring 1 31 , and the buffer spring 1 31 plays a buffering role.
[0028] The outer ends of both ends of the second slide bar 37 are inserted into the inner ring of the second buffer spring 36 , and the two ends of the second buffer spring 36 are supported between the slide block 38 and the connecting block 35 .
[0029] Furthermore, when the bearing plate 13 moves axially along the second slide bar 37 , the bearing plate 13 drives the slider 38 to move axially along the second slide bar 37 , and the slider 38 compresses the buffer spring 36 , so that the buffer spring 36 plays a buffering role.
[0030] The bearing assembly 1 includes a bearing plate 13 , the bottom of which is fixedly connected to the top of the slider 38 , and the top of the bearing plate 13 is provided with a limiting groove 14 , the bottom of which is movably connected to the bottom of the circuit board body 2 .
[0031] The edge of the top of the carrier plate 13 is threadedly connected to the outside of the screw 11 , and the outside of the screw 11 is slidably inserted into the inside of the crimping plate 12 , which is located at the top of the circuit board body 2 .
[0032] Furthermore, the screw 11 is turned to move the screw 11 toward the bearing plate 13 , and the screw 11 drives the crimping plate 12 to move toward the bearing plate 13 , so that the crimping plate 12 crimps the circuit board body 2 , and the circuit board body 2 cannot escape from the limiting groove 14 .
[0033] The bottom of the carrier plate 13 is fixedly connected to the top of a plurality of groups of heat sinks 15 .
[0034] Furthermore, the heat generated by the circuit board body 2 during operation is transferred to the carrier plate 13 , and the carrier plate 13 transfers the heat to the heat sink 15 . The heat sink 15 increases the heat dissipation area and makes the heat dissipation speed faster.
[0035] An antistatic layer 21 is coated on the top of the circuit board body 2; wherein the antistatic layer 21 includes: a graphene layer 214, the graphene layer 214 is coated on the outside of the circuit board body 2, a nano polyurethane layer 213 is provided on the outside of the graphene layer 214, an iron oxide layer 212 is provided on the outside of the nano polyurethane layer 213, and a polytetrafluoroethylene layer 211 is provided on the outside of the iron oxide layer 212.
[0036] Furthermore, the graphene layer 214 has a two-dimensional crystal structure. Its lattice is a hexagon formed by six carbon atoms, and its thickness is one atomic layer. Since there is only one layer of atoms, the movement of electrons is restricted to a plane. Therefore, graphene has good electrical conductivity, and further, it can endow the coating with the ability to dissipate static charges; the nano-polyurethane layer 213 has good anti-static effect, better color and luster, rich varieties, and good decorative properties; the iron oxide layer 212 is an anti-rust layer, and the polytetrafluoroethylene layer 211 is an anti-corrosion layer, which can protect the outside of precision instruments and enable them to have a longer service life.
[0037] Working principle: When in use, place the circuit board body 2 in the limiting groove 14 at the top of the carrier plate 13, and then turn the screw 11, so that the screw 11 moves towards the carrier plate 13. The screw 11 drives the crimping plate 12 to move towards the carrier plate 13, so that the crimping plate 12 crimps the circuit board body 2, making the circuit board body 2 unable to break away from the limiting groove 14. At the same time, the bottom of the circuit board body 2 is closely attached to the bottom of the limiting groove 14, so as to transfer the heat generated during the operation of the circuit board body 2 to the carrier plate 13. The carrier plate 13 transfers the heat to the heat sink 15. The heat sink 15 increases the heat dissipation area and makes the heat dissipation speed faster; at the same time, the graphene layer 214 in the anti-static layer 21 has good electrical conductivity, which can endow the coating with the ability to dissipate static charges. The nano-polyurethane layer 213 has good anti-static effect. The iron oxide layer 212 mainly plays an anti-rust role, and the polytetrafluoroethylene layer 211 plays an anti-corrosion role, which can protect the outside of precision instruments.
[0038] When a collision or shock occurs and the circuit board body 2 and the carrier plate 13 move up and down, the carrier plate 13 pushes the slider 38 downward. The slider 38 pushes the connecting block 35 and the first slide bar 33 downward through the second slide bar 37. The first slide bar 33 drives the moving strip 39 to move downward. While the moving strip 39 moves downward, the diagonal strut 34 pushes the moving strip 39 towards the connecting block 35, causing the moving strip 39 to compress the first buffer spring 31. Then, the first buffer spring 31 plays a buffering role; when the carrier plate 13 moves axially along the first slide bar 33, the carrier plate 13 will drive the connecting block 35 to move axially along the first slide bar 33 through the slider 38 and the second slide bar 37, causing the connecting block 35 to stretch or compress the first buffer spring 31, and the first buffer spring 31 plays a buffering role; when the carrier plate 13 moves axially along the second slide bar 37, the carrier plate 13 will drive the slider 38 to move axially along the second slide bar 37, and the slider 38 compresses the second buffer spring 36, and the second buffer spring 36 plays a buffering role; in this way, the buffer assembly 3 can form buffer protection for the circuit board body 2 in multiple directions.
[0039] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
