Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 As shown, a double-sided multi-layer circuit board anti-cracking device includes a circuit board 1, and a protective mechanism 2 is installed on the circuit board 1. The protective mechanism 2 includes a pad 201, and four groups of snap-fit pads 201 are respectively connected at the four corners of the circuit board 1. A sink 206 is provided on one side of the pad 201, and a rubber sleeve 207 is fixedly connected to the center of one side of the pad 201. One end of the rubber sleeve 207 extends into the inside of the sink 206, and the other end of the rubber sleeve 207 extends to the outside of the pad 201. One end of the rubber sleeve 207 is slidably connected to the inside of the circuit board 1, and a screw 204 is slidably connected to the inside of the rubber sleeve 207. A heat dissipation mechanism 3 is provided on the top side of the circuit board 1.

[0021] As a technical optimization solution of the present invention, a rubber pad 209 is provided inside the sink 206. One side of the rubber pad 209 is connected to the pad 201, and the other side of the rubber pad 209 is in contact with the side wall of the circuit board 1. The installation of the rubber pad 209 is conducive to the two buckled pads 201 to stably clamp the circuit board 1, and plays a role in reducing pressure and buffering the circuit board 1, so that the circuit board 1 is not easy to break.

[0022] As a technical optimization solution of the present invention, a reinforcement plate 205 is connected between the two pads 201. Connection holes 208 are provided at both ends of the reinforcement plate 205. The connection holes 208 are engaged with the top of the rubber sleeve 207. The installation of the reinforcement plate 205 is conducive to reinforcing the connection between the two pads 201, so that the circuit board 1 will not be easily bent and damaged. The opening of the connection holes 208 facilitates the disassembly and assembly of the reinforcement plate 205.

[0023] As a technical optimization solution of the present invention, the four sides of the circuit board 1 are respectively connected with anti-collision strips 202, and the cross-section of the anti-collision strip 202 is a "concave"-shaped structure. Through the snap-fit installation of the four anti-collision strips 202, it is beneficial to protect the side wall of the circuit board 1 from cracking, and prevent the burrs on the side wall of the circuit board 1 from scratching hands.

[0024] As a technical optimization solution of the present invention, the circuit board 1 is provided with a plurality of equally spaced pressure relief grooves 203, and the pressure relief grooves 203 are elliptical structures. The opening of the pressure relief grooves 203 is conducive to making the circuit board 1 have good flexibility, playing the role of reducing pressure and unloading force, and effectively preventing the circuit board 1 from breaking.

[0025] As a technical optimization solution of the present invention, the heat dissipation mechanism 3 includes a support rod 301, and the support rod 301 is vertically threaded at the center of the top of the two reinforcement plates 205. A heat dissipation plate 302 is provided on the top of the circuit board 1. The two ends of the heat dissipation plate 302 are fitted with the top of the support rod 301 through fixing holes 304. The installation of the two support rods 301 is conducive to supporting and connecting the heat dissipation plate 302. Under the action of the heat dissipation plate 302, it is convenient to absorb and discharge the heat on the circuit board 1, which plays a good heat dissipation effect and protects the safe operation of the circuit board 1.

[0026] As a technical optimization solution of the present invention, the top of the support rod 301 is threadedly connected with a bolt 306, and the bolt 306 interferes with the heat sink 302. The bolt 306 cooperates with the heat sink 302 to facilitate disassembly and assembly of the heat sink 302, which is beneficial for subsequent maintenance.

[0027] As a technical optimization solution of the present invention, the area of the heat sink 302 is equal to the area of the circuit board 1, and a plurality of equidistantly distributed heat dissipation holes 303 are provided on the heat sink 302. The opening of the heat dissipation holes 303 is conducive to ventilation and diversion, thereby achieving a better heat dissipation effect.

[0028] As a technical optimization solution of the present invention, multiple grooves 305 are provided on the side walls at both ends of the heat sink 302, and the widths of the multiple grooves 305 are equal. The opening of the multiple grooves 305 is conducive to reducing the weight and also plays a role in ventilation and heat dissipation, so that the heat around the heat sink 302 is dissipated faster.

[0029] When the utility model is used, first, multiple pads 201 are symmetrically buckled on the four corners of the circuit board 1, and the rubber sleeves 207 inside the pads 201 pass through the circuit board 1 and conflict with each other, thereby clamping the circuit board 1. The pads 201 are provided with a sink groove 206 and a rubber pad 209, which play a role in clamping and stabilizing the circuit board 1 and protecting the circuit board 1, so that the circuit board 1 can be buffered by external forces without being damaged. Then, the two reinforcement plates 205 are clamped with the tops of the two pads 201 and are tightly inserted and tightened by the screw 204. Under the action of the pads 201, the screw When 204 is tightened, it will not squeeze and crack the circuit board 1. A decompression groove 203 is opened on the circuit board 1 to make the circuit board 1 have a certain toughness and effectively prevent it from breaking. Finally, the two support rods 301 are vertically threaded with the reinforcement plate 205 to support the heat sink 302 and fastened by bolts 306. Under the action of the heat sink 302, it is beneficial to absorb the heat generated by the circuit board 1. Under the action of the heat dissipation holes 303, air flow is allowed to flow, so that heat is dissipated, which plays a good heat dissipation effect, protects the circuit board 1 to work normally, and is not easy to crack.
