In addition, the conductive particles 10 are mounted in the spacing grooves 25 of the first support 20. The circuit board 230 is fixed to the upper cover 210 by the locking member 240, and in this embodiment, there are two locking members 240, and the circuit board 230 is fixed by the locking members 240 so that the circuit board 230 is parallel to the upper cover 210. Aligning the upper cover 210 with the lower cover 220, contacting the bottom surface of the circuit board 230 with the top wall 21 of the first bracket 20, during the process of fixing the upper cover 210 to the lower cover 220, the first bracket 20 is pressed by the circuit board 230, the first bracket 20 moves downward to push the bump 24 to slide downward from the opening 37 along the rail 36, the elastic element 40 is stretched to move the second bracket 30 in the direction a away from the fixing post 60, the second bracket 30 moves in the rail 512 in the direction a and continues to press downward until the bump 24 runs to the lowest position of the rail 36, the distance between the second bracket 30 and the fixing post 60 is farthest, and the elastic element 40 is stretched to the longest, at this time, the upper cover 210 is assembled with the lower cover 220, and the conductive particles 10 contact with the corresponding metal pads of the circuit board 230 to generate corresponding signals, so that the electronic device works normally.
When the upper cover 210 and the lower cover 220 are separated during illegal disassembly, the upper cover 210 and the circuit board 230 are removed, the first bracket 20 is not stressed, due to the elastic restoring force of the elastic element 40, the elastic element 40 pulls the second bracket 30 to move towards the direction B close to the fixing post 60, and due to the accumulation and release of the elastic restoring force of the elastic element 40, the latch 34 of the second bracket 30 is disengaged from the sliding slot 512, the elastic element 10 enables the second bracket 30 to be rapidly pulled out of the base 50, and the bump 24 of the first bracket 20 is disengaged from the rail slot 36 of the second bracket 30, due to the gravity imbalance of the first bracket 20, one end of the first bracket 20 is overturned and contacts with the bottom wall 31 of the second bracket 30, and at this time, the conductive particle 10 is disengaged from the limiting slot 25. Since the illegal detacher does not know which of the position-limiting grooves 25 the conductive particles 10 are placed in the initial state, it is difficult for the illegal detacher to correctly place the conductive particles in the original position-limiting grooves 25 during assembly, and the electronic device 200 cannot normally operate when the arrangement sequence of the conductive particles is changed.
In addition, the number of the conductive particles 10 and the spacing grooves 25 may be increased to increase the difficulty of assembling by illegal users.
The lifting and pulling-out structure 100 and the electronic device 200 using the lifting and pulling-out structure 100 provided by the invention are fixed by the matching movement of the first support 20 and the second support 30 under the action of external force, and the first support 20 is separated from the second support 30 and overturned by virtue of the elastic restoring force of the elastic element 40, so that the conductive particles 10 are pulled out of the limiting groove 25 of the first support 20, the correct position of the conductive particles 10 is difficult to judge, an illegal detacher is difficult to correctly assemble, a user can judge whether the electronic device 200 is illegally detached or not, and the electronic device 200 cannot normally operate because the conductive particles are simultaneously pulled out of the limiting groove during illegal detachment, thereby reducing the risk of data theft.
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.
