Referring to FIG. 1, a cross-sectional view of a shockproof locking assembly device according to a first embodiment of the invention is shown. In FIG. 1, the shockproof locking assembly device 10 is disposed between a first housing 11 and a second housing 12. The shockproof locking assembly device 10 is for connecting the first housing 11 and a second housing 12. The shockproof locking assembly device 10 is for preventing the first housing 11 and the second housing 12 from vibrating when the first housing 11 or the second housing 12 receives an external force. The shockproof locking assembly device 10 includes a locking hole member 14, a cavity member 13, a locking element 15 and a vibration-absorbing element 16. The cavity member 13 has a bottom portion 13a. The bottom portion 13a has a through hole 13b. The wall of the through hole 13b has a recess 13c. The cavity member 13 is like a cavity member of a sunk fish eye.
The locking element 15 includes a head portion 15a, a shaft portion 15b and a link portion 15c. The link portion 15c is for connecting the head portion 15a and the shaft portion 15b. The head portion 15a is disposed inside the cavity member 13. The shaft portion 15b penetrates the through hole 13b to be locked into the locking hole member 14, so that the head portion 15a and the shaft portion 15b are respectively positioned on the top side and the down side of the bottom portion 13a. The lateral surface of the link portion 15c has a protrusion 15d corresponding to the recess 13c. The protrusion 15d has a taper level. The link portion 15c extends towards the shaft portion 15b from the head portion 15a to connect the head portion 15a and the shaft portion 15b. The inner diameter of the link portion 15c along the x direction grows larger first and then shrinks gradually, so that the protrusion 15d disposed on the lateral surface of the link portion 15c have the above taper level. Besides, the head portion 15a, the shaft portion 15b and the link portion 15c can be a one-piece molding structure, and the taper level of the protrusion 15d can be Morse taper level, Brown & Sharpe taper level, milling machine standard taper level or Jarno taper level.
The vibration-absorbing element 16 penetrates the through hole 13b, encompasses the link portion 15c and clamps the bottom portion 13a. The shaft portion 15b penetrates through the vibration-absorbing element 16, and the protrusion 15d is coupled with the recess 13c via part of the vibration-absorbing element 16. The vibration-absorbing element 16 can be an I-shaped hollowed shrink-ring.
When the first housing 11 or the second housing 12 receives an external force, due to the design that the vibration-absorbing element 16 tightly contacts the first housing 11 and the second housing 12, the vibration-absorbing element 16 can absorb the external force received by the first housing 11 or the second housing 12 to prevent the first housing 11 and the second housing 12 from vibrating, thereby enhancing the shockproof strength between the first housing 11 and the second housing 12.
However, anyone who is skilled in the technology of the present embodiment will understand that the technology of the present embodiment of the invention is not limited thereto. For example, in FIG. 1, the protrusion 15d and the recess 13c respectively are a peak and a valley. The angle α contained at the apex of the peak is larger than or equal to the angle β contained at the bottom of the valley, so that the strength of the connection between the protrusion 15d and the recess 13d via part of the vibration-absorbing element 16 is enhanced. Besides, as shown in FIG. 1, the vibration-absorbing element 16 further includes a first rib portion 16a and a second rib portion 16b. The first rib portion 16a and the second rib portion 16b respectively encompass the outside lateral surface of the top portion and the bottom portion of the vibration-absorbing element 16. The first rib portion 16a and the second rib portion 16b are respectively positioned on the top side and the down side of the bottom portion 13a. The first rib portion 16a and the second rib portion 16b are for clamping the bottom portion 13a. Besides, a vibration-isolating element 17 can be disposed on the head portion 15a. The vibration-isolating element 17 can be positioned inside the cavity member 13. Moreover, as shown in FIG. 1, since the second housing 12 and the bottom portion 13a are interspaced by a distance, a vibration-isolating element 18 can be disposed between the second housing 12 and the first housing 11. The shaft portion 15b and the locking hole member 14 respectively are a screw rod and a screw hole. The vibration-absorbing element 16, and the vibration-isolating elements 17 and 18 can be an elastomer made of elastic materials such as rubber, plastics or polymer.
According to the present embodiment, the locking hole member 14 can be disposed in a hard disc housing of a hard disc. That is, the first housing 11 can be a hard disc housing. The cavity member 13 can be disposed in a carrier. That is, the second housing 12 can be a carrier. The carrier can be disposed on a motherboard of a notebook computer, so that hard disc can be disposed on the motherboard via the carrier. Thus, the notebook computer is prevented from vibrating when receiving an external force or falling to the ground, lest the data stored in the hard disc might be damaged when the hard disc vibrates or receives an external force, thus maintaining the completeness of the data stored in the hard disc.

The cavity member 13 is disposed in the cover 22, and the locking hole member 14 is disposed in the hard disc housing 21a. 
When the notebook computer 20 receives an external force or falls to the ground, due to the design that the vibration-absorbing element 16 tightly contacts the hard disc housing 21a and the cover 22 and that the cover 22 is buckled with the computer housing 23, the vibration-absorbing element 16 can absorb the external force received by notebook computer 20 to prevent the notebook computer from vibrating, thereby enhancing the shockproof strength of the hard disc housing 21a and the upper cover. Moreover, the design prevents the hard disc 21 from vibrating, so that the data stored in the hard disc 21 will not be damaged due to the vibration or collision of the hard disc, thereby maintaining the completeness of the data stored in the hard disc 21.
However, anyone who is skilled in the technology of the present embodiment of the invention will understand that the technology of the present embodiment of the invention is not limited thereto. For example, a vibration-isolating element 27 can further be disposed on the head portion 15a. The vibration-isolating element 27 can be positioned inside the cavity member 13. Besides, as shown in FIG. 2, since the cover 22 and the bottom portion 13a are interspaced by a distance, a vibration-isolating element 28 can be disposed between the cover 22 and the hard disc housing 21a.
