[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] To ensure better heat dissipation and stability during use, such as... Figure 1-6 As shown, the high-stability smart home host motherboard of this utility model includes a circuit board body 1, a heat spreader 2, a CPU 7, a flash memory chip 12, an inductor 13 and a capacitor 14. The CPU 7 is arranged near the center of the circuit board body 1, and the flash memory chip 12, the inductor 13 and the capacitor 14 are also arranged on the circuit board body 1.
[0027] A heat spreader 2 is provided on one side of the circuit board body 1. A rectangular groove 8 is provided through one side of the heat spreader 2 at the position corresponding to the CPU 7. A semi-open circular groove 15 is provided on the inner wall of the rectangular groove 8 near the corner. A lower retaining groove 16 is provided on the inner wall of the semi-open circular groove 15 near the bottom. A circular piece 20 is provided in the lower retaining groove 16. A stud 21 is connected to the top of the circular piece 20. A nut 22 is sleeved on the outer periphery of the top of the stud 21. A rubber limiting block 18 is also provided in the semi-open circular groove 15. The rubber limiting block 18 is sleeved on the outer periphery of the stud 21.
[0028] In use, the rubber limiting block 18 is pre-fixed by inserting the circular piece 20 into the lower slot 16, and then the rubber limiting block 18 is embedded in the semi-open circular groove 15. The nut 22 is tightened so that the heat sink bracket is locked between the nut 22 and the rubber limiting block 18, thus achieving efficient heat dissipation for the CPU7. This motherboard has good heat dissipation and better stability during use.
[0029] For example, such as Figure 5 As shown, the present invention also includes a limiting protrusion 19 on the periphery of the rubber limiting block 18, and an upper slot 17 is provided on the inner wall of the semi-open circular groove 15 near the upper end of the lower slot 16, and the limiting protrusion 19 is engaged in the upper slot 17.
[0030] In use, the upper slot 17 can be used to limit the limiting protrusion 19, thereby making it easy to fix the rubber limiting block 18 in the semi-open circular groove 15.
[0031] For example, such as Figure 5 and 6 As shown, the present invention also includes a first convex cover 5 disposed on the heat spreader 2 at a position corresponding to the inductor 13 and the capacitor 14, and a second convex cover 6 disposed on the heat spreader 2 at a position corresponding to the flash memory chip 12.
[0032] In use, the first convex cover 5 facilitates better contact between the heat spreader 2 and the part of the circuit board body 1 near the inductor 13 and capacitor 14, and the second convex cover 6 facilitates better contact between the heat spreader 2 and the part of the circuit board body 1 near the flash memory chip 12.
[0033] For example, such as Figure 2 As shown, the present invention also includes a second screw 4 provided through a reserved hole on the outer wall of the heat spreader 2 near the corner, a first screw 3 provided through a reserved hole on the outer wall of the heat spreader 2 near the corner of the rectangular groove 8, and a circular pad 10 provided on the outer wall of the circuit board body 1 at the corresponding positions of the first screw 3 and the second screw 4, and a threaded groove 11 provided on the circular pad 10.
[0034] In use, by tightening the first screw 3 and the second screw 4, the first screw 3 and the second screw 4 cooperate with the corresponding threaded groove 11 to easily lock and fix the heat spreader 2 to one side of the circuit board body 1.
[0035] For example, such as Figure 3 As shown, the present invention also includes a strip groove 9 at the bottom of the rectangular groove 8 that communicates with one side of the heat spreader 2.
[0036] During use, the strip groove 9 allows the heat spreader 2 to have a certain degree of freedom of deformation when subjected to stress, making it less prone to rigid damage.
[0037] For example, such as Figure 1-3 As shown, the present invention also includes an epoxy resin flame retardant layer on the outer surface of the circuit board body 1.
[0038] When in use, the epoxy resin flame retardant layer can effectively improve the flame retardant effect of the outer surface of the circuit board body 1, which is conducive to improving the reliability of the circuit board body 1 during use.
[0039] In use, the circuit board body 1 of this invention is also provided with other interfaces and modules related to smart homes, which are used to realize the basic control and communication functions of the smart home host motherboard.
[0040] By inserting the circular piece 20 into the lower slot 16, the rubber limiting block 18 is pre-fixed. Then, by embedding the rubber limiting block 18 into the semi-open circular groove 15, the rubber limiting block 18 limits the stud 21 at the top of the circular piece 20. The hole on the external heatsink mounting bracket passes through the rubber limiting block 18. After tightening the nut 22, the heatsink bracket is locked between the nut 22 and the rubber limiting block 18. At this point, the bottom of the heatsink contacts the top of the CPU 7, achieving efficient heat dissipation for the CPU 7.
[0041] Furthermore, thermally conductive silicone pads can be pre-laid on the inner walls of the first convex cover 5 and the second convex cover 6. When the first screw 3 and the second screw 4 are tightened, so that the circuit board body 1 is in close contact with the heat spreader 2, the thermally conductive silicone pads come into contact with the flash memory chip 12, the inductor 13 and the capacitor 14. This allows the heat generated by the flash memory chip 12, the inductor 13 and the capacitor 14 during operation to be uniformly conducted through the heat spreader 2. Thus, the heat spreader 2 can provide auxiliary heat dissipation for other parts of the motherboard. The motherboard has good heat dissipation effect and better stability during use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
