[0015] Reference will now be made in detail to the exemplary embodiments of the present application, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used in the drawings and the description to refer to the same or like parts.

[0016] Figure 1 is a disassembled state schematic diagram of an electronic device of one embodiment of the present application. Figure 2 is a partial sectional view of the assembled state of the electronic device of Figure 1 . Please refer to Figure 1 and Figure 2 , the electronic device 100 of the present embodiment comprises a first casing 110, a second casing 120, a memory chip 130, a detection circuit 140 and a data erasing circuit 150. The second casing 120 is assembled to the first casing 110 and together forms a receiving space S10. The memory chip 130 is disposed in the receiving space S10. The detection circuit 140 is electrically connected to the memory chip 130. The detection circuit 140 comprises a first section 142 and a second section 144 which are physically connected. The first section 142 is fixed to the first casing 110. The second section 144 is fixed to the second casing 120. The data erasing circuit 150 is electrically connected to the memory chip 130 and the detection circuit 140.

[0017] ​The first segment 142 is fixed to the first casing 110 means that the first segment 142 is directly or indirectly fixed to the first casing 110, and the first casing 110 is moved with the first segment 142. Similarly, the second segment 144 is fixed to the second casing 120 means that the second segment 144 is directly or indirectly fixed to the second casing 120, and the second casing 120 is moved with the second segment 144.

[0018] Because the first segment 142 is fixed to the first casing 110 and the second segment 144 is fixed to the second casing 120, when the first casing 110 is separated from the second casing 120, the first segment 142 and the second segment 144 are physically disconnected. When the first segment 142 and the second segment 144 of the detection loop 140 are physically disconnected, the data clearing circuit 150 clears the data stored in the memory chip 130 when powered. That is, when someone attempts to break the electronic device 100 by external force to obtain the internal memory chip 130, the data stored in the memory chip 130 will be cleared and will not be obtained by the breaker. Therefore, the holder of the electronic device 100 does not need to worry about the data stored in the memory chip 130 being stolen. Of course, the holder of the electronic device 100 can obtain and use the data stored in the memory chip 130 by identity verification without breaking the electronic device 100.

[0019] For example, the memory chip 130 stores financial information. That is, the electronic device 100 can be an electronic wallet or a personal key. Because the electronic device 100 has the above protection mechanism, the financial security of the user can be guaranteed. In other embodiments, the electronic device 100 can also be a head-mounted display device or other electronic devices. Because the electronic device 100 can also store the user's personal biological characteristics or other confidential data, such as fingerprints, faces, retinas, or irises, the electronic device 100 with the above protection mechanism will make the user feel safe in use.

[0020] In the embodiment, the electronic device 100 can further include an energy storage component 160 connected and used to power the data clearing circuit 150 and the detection loop 140. Because the energy storage component 160 powers the detection loop 140, whether the first segment 142 and the second segment 144 are connected or physically disconnected can be determined according to whether the detection loop 140 forms an electrically conductive loop. When the energy storage component 160 powers the data clearing circuit 150 and it is determined that the first segment 142 and the second segment 144 are physically disconnected, the data clearing circuit 150 clears the data stored in the memory chip 130. The energy storage component 160 is, for example, a capacitor or other energy storage component.

[0021] When the electronic device 100 does not include the energy storage component 160, power is needed to attempt to read the data stored in the memory chip 130. At the same time, the data clearing circuit 150 and the detection circuit 140 are also powered, so it is also possible to determine whether the first section 142 and the second section 144 are physically disconnected. When it is determined that the first section 142 and the second section 144 are physically disconnected, the data clearing circuit 150 also clears the data stored in the memory chip 130.

[0022] Figure 3 is Figure 1 a partial view of the electronic device after the first casing is removed. Please refer to Figure 2 and Figure 3 In this embodiment, the electronic device 100 also includes a circuit board 170. The detection circuit 140 and the memory chip 130 are disposed on the circuit board 170. The circuit board 170 includes a main board 172 and a tongue board 174. The first section 142 of the detection circuit 140 and the memory chip 130 are located on the main board 172. The second section 144 of the detection circuit 140 is located on the tongue board 174. The main board 172 is fixed to the first casing 110. That is, the main board 172 is directly or indirectly fixed to the first casing 110, and the first casing 110 is moved together with the main board 172. The tongue board 174 is fixed to the second casing 120. That is, the tongue board 174 is directly or indirectly fixed to the second casing 120, and the second casing 120 is moved together with the tongue board 174.

[0023] Therefore, when someone attempts to break the electronic device 100 by external force to obtain the internal memory chip 130, the first casing 110 and the second casing 120 are separated, the main board 172 and the tongue board 174 are also separated, and the first section 142 and the second section 144 are physically disconnected.

[0024] In this embodiment, the circuit board 170 is formed as a whole, and the circuit board 170 has a row of through holes 176 at the junction of the main board 172 and the tongue board 174. Since the circuit board 170 is originally formed as a whole, in order to ensure that the main board 172 and the tongue board 174 are broken from the junction of the two, a row of through holes 176 is provided at the junction.

[0025] In the present embodiment, the electronic device 100 further comprises a fastener 180 fixed to the second casing 120. The tongue 174 has a fastener hole 174A. The fastener 180 passes through the fastener hole 174A and clamps the tongue 174 between the fastener 180 and the second casing 120. For example, the fastener 180 can be welded to the second casing 120. The portion of the fastener 180 not fixed to the second casing 120 can pass through the fastener hole 174A first, and then the portion of the fastener 180 passing through the fastener hole 174A is bent to hold the tongue 174. Thus, when the second casing 120 moves, the tongue 174 can be driven to move together via the fastener 180.

[0026] In the present embodiment, the electronic device 100 can further comprise a frame 192 and an adhesive layer 194. The frame 192 is used to provide support between the first casing 110 and the second casing 120. The main board 172 of the circuit board 170 is fixed to the first casing 110 via the adhesive layer 194. In addition, although the storage chip 130, the detection circuit 140, the data clearing circuit 150 and the energy storage component 160 are arranged on the upper surface of the circuit board 170 in the present embodiment, in other embodiments, these components can also be arranged on the lower surface of the circuit board 170. In this way, the circuit board 170 can be fixed to the first casing 110 via the adhesive layer 194 by the flat upper surface. Figure 1

[0027] In summary, in the electronic device of the present application, as long as the electronic device is damaged to cause the first casing and the second casing to separate, the detection circuit is physically disconnected, and the data stored in the storage chip is cleared by the data clearing circuit. Thus, the data stored in the electronic device can be effectively protected.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.​
