The following describes the mounting and dismounting of the electronic device 200 to which the above-mentioned tamper-proof structure 100 is applied, with reference to fig. 1 to 5:
during installation, in the first step, the alarm assembly 130 is installed on the first fixing member 120 of the upper cover 210, specifically, the limiting column 125 sequentially passes through the through hole 1323 of the circuit board 132 and the limiting hole 1315 of the trigger 131; then, the alarm assembly 130 is mounted by screwing the screw through the fixing hole 1321 of the circuit board 132 and onto the fixing post 124, and at this time, the limiting post 125 is matched with the limiting hole 1315 to limit the rotation range of the trigger 131.
Secondly, mounting the anti-disassembly assembly 110 on the first fixing member 120, specifically, sequentially passing the first connecting portion 1114 and the first tooth portion 1113 of the first locking member 111 through the first through hole 123, and mounting the first sleeving portion 1112 in the first through hole 123; then the first tooth part 1113 is engaged to the second tooth part 1312 of the trigger 131; finally, the boss 1123 of the detachment preventing member 112 is engaged with the recess 1221 of the second mounting portion 122, so that the detachment preventing member 112 is fixed to the second mounting portion 122, and at this time, the first cap 1111 is mounted on the first mounting portion 121 and abuts against the bottom wall of the first mounting portion 121.
Thirdly, mounting the fixing assembly 150 on the second fixing member 140 of the bottom case 220, specifically, sequentially passing the second connecting portion 1514 and the card slot 1513 of the second locking member 151 through the second through hole 142; the second spigot 1512 is then rotatably mounted within the second through hole 142 and the second cap portion 1511 is abutted against the inner bottom wall 1411 of the third mounting portion 141; finally, the fastening member 152 is movably mounted in the engaging groove 1513 and abuts against the outer bottom wall 1412 of the third mounting portion 141, so that the second fastening member 151 can be rotatably mounted on the second fastening member 140, and due to the limiting effect of the fastening member 151 and the second cap portion 1511, the second fastening member 151 cannot move relative to the second fastening member 140 during rotation.
Fourthly, the upper cover 210 is assembled to the bottom case 220, specifically, the first connecting portion 1114 of the first locking member 111 is aligned to the second connecting portion 1514 of the second locking member 151, then the upper cover 210 is fastened to the bottom case 220, finally the second locking member 151 is rotated, the external thread on the second connecting portion 1514 is screwed with the threaded hole on the first connecting portion 1114, and the first cap portion 1111 presses the upper cover 210 to the bottom case 220 until the upper cover 210 is pressed to the bottom case 220.
When detaching, first rotate the second locking member 151 along a set direction, for example, rotate the second locking member 151 along a counterclockwise direction, the second locking member 151 first applies a force to the first locking member 111 to break the breakable structure between the detachment prevention portion 1122 and the detachment prevention body 1121, and at this time, the first locking member 111 rotates relative to the upper cover 210 through the cooperation of the first sleeving portion 1112 and the first through hole 123; then, the first locking element 151 drives the second locking element 111 to rotate, the second locking element 111 drives the trigger element 131 to rotate, the arc portion 1317 of the trigger element 131 slides relative to the limiting column 125, so that the trigger elastic piece 1331 of the micro switch 133 slides out of the trigger recess 1316 and slides along the trigger portion 1313 to turn on the micro switch 133, the micro switch 133 sends a signal to enable the circuit board 132 to send alarm information, and a processor in the main board of the electronic device 200 removes data in the electronic device 200 or locks a starting-up program; then, the end 1318 of the triggering member 131 away from the triggering recess 1316 abuts against the limiting column 125, so that the triggering member 131 cannot rotate continuously and the first locking member 111 is prevented from rotating; finally, under the continuous action of the second locking member 151, the first locking member 111 moves away from the second locking member 151, so as to eject the anti-detachment member 112 from the upper cover 210, and the first locking member 111 is also disengaged from the second locking member 151, so as to detach the upper cover 210 from the bottom case 220.
Therefore, according to the anti-tamper structure 100 and the electronic device 200 using the anti-tamper structure 100 provided by the invention, the first locking piece 111 and the alarm component 130 are connected together, when the first locking piece 111 rotates under stress, the alarm component 130 is triggered, and the alarm component 130 sends out an alarm signal, so that a processor in the electronic device 200 clears data in the electronic device 200 or locks a boot program, and data leakage in the electronic device 200 is avoided; the first locking member 111 is provided with a detachment prevention member 112, and when the first locking member 111 is forced to rotate to a certain position, the first locking member 111 will eject the detachment prevention member 112 out of the upper cover 210, so that the detachment prevention member 112 is damaged, and whether the electronic device 200 has any trace of artificial damage is easily determined.
It will be apparent to those skilled in the art that other corresponding changes and modifications can be made according to the actual needs created by the inventive arrangements and inventive concepts herein, and such changes and modifications are intended to fall within the scope of the appended claims.
