Abstract:
A shock-absorbing device for a notebook computer module, comprising of:a silicon chip;a printed circuit board having a chip-mounting region, wherein the chip-mounting region has a front face and a back face, and the silicon chip is mounted onto the front face of the chip-mounting region;a backing plate mounted onto the back face of the printed circuit board within the chip-mounting region;a cooling/protective plate mounted onto the front face of the chip-mounting region such that the cooling/protective plate not only covers the silicon chip but also contacts the silicon chip;a first spring installed between the printed circuit board and the cooling/protective plate with one end of the spring touching the printed circuit board and the other end of the spring touching the cooling/protective plate, the first spring exerting a first reaction force is on the printed circuit board and a second reaction force on the cooling/support plate, and both the first reaction force and the second reaction force are of the same magnitude but act in opposite directions in trying to move the printed circuit board away from the cooling/support plate;a fastening insert that passes through the cooling/protective plate, the fastening insert having a first end and a second end, the second end contacting the front face of the printed circuit board, and the cooling/protective plate being somewhere between the first and the second end of the fastening insert; anda second spring slid over the fastening insert such that one end of the second spring pushes against a flange at the first end of the fastening insert and the other end of the second spring pushes against the cooling/protective plate, the second spring exerting a third reactive force on the cooling/protective plate and a fourth reactive force on the first end of the fastening insert, and both the third reaction force and the fourth reaction force being of the same magnitude but act in opposite directions in trying to move the cooling/support plate closer to the printed circuit board;wherein the first spring and the second spring are alternatingly placed around the peripheral regions of the cooling/protective plate.
