Problems solved by technology

However, since the anti-dismantlement label is simply pasted on the body of the electronic device, the user may damage the anti-dismantlement label when using the electronic device normally, thereby causing a misjudgment whether the user has dismantled the device without permission.

Abstract

A housing containing its own record of any private and unwarranted disassembly includes a first shell, a second shell detachably connected with the second shell, a consumer disassembly indication structure. The consumer disassembly indication structure includes a circuit board, a plurality of switches, a computer chip, a plurality of conductive bodies, and a plurality of insulative bodies. The plurality of switches are fixed on the circuit board and each is electrically connected with the computer chip. The computer chip is configured to record electric connections between the conductive bodies and switches, the original electric connections being changed to other or no connections after any disassembly of the housing.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device for detecting whether the electronic device has been disassembled. Background technique [0002] In order to prevent the electronic device from being disassembled by the user during the warranty period, the manufacturer will paste an anti-disassembly label on the junction of the upper cover and the lower cover of the electronic device. The tamper-evident label is made of fragile paper material, and when the user disassembles the machine without permission, the tamper-evident label will inevitably be damaged. When the electronic device is returned to the factory for maintenance, it is judged whether the electronic device has been disassembled by the user according to the completeness of the tamper-evident label. However, since the anti-dismantlement label is simply pasted on the body of the electronic device, the user may damage the anti-dismantlement label when using ...
