Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic devices, and in particular to a safety structure and electronic devices. Background Art

[0002] Regarding the security of electronic devices, intruders may open the housing and tamper with the interior of the device. Therefore, installing an anti-tamper switch inside the electronic device can be used to monitor the disassembly of the electronic device, facilitating the timely detection of any disassembly of the electronic device housing. The housing of the electronic device presses the anti-tamper switch, keeping it on. Once the housing is abnormally opened, the pressure on the anti-tamper switch disappears, the anti-tamper switch is disconnected, and the abnormal electrical signal is recorded, thereby detecting the disassembly of the electronic device housing.

[0003] However, an intruder can dismantle the electronic device's housing by inserting a card through the gap in the housing and pressing the anti-tamper switch, thereby bypassing the electronic device's firewall detection and causing information leakage. In addition, after high and low temperature environmental testing, the anti-tamper switch has a certain defect rate of switch failure, which requires glue to be applied around the anti-tamper switch, which undoubtedly increases costs. In some projects, the electronic device cannot be fully assembled, but is directly shipped after being installed on the motherboard. To prevent the switch from falling off during transportation, a protective film must be applied to the anti-tamper switch, which also increases labor and material costs. Summary of the Invention

[0035] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0036] According to one embodiment of the present disclosure, Figure 1-7 As shown, the present invention provides a safety structure, which is applied to an electronic device 2. The electronic device includes a first housing 21, a second housing 22 and a mainboard 23. The safety structure 1 includes:

[0037] The rotating bracket 11 is detachably and rotatably mounted on the first shell 21;

[0038] The electrode 12 is provided on the rotating bracket 11, and the electrode 12 has a first electrode end 121 and a second electrode end 122;

[0039] The hook 13 is provided on the second shell 22; wherein,

[0040] When the second housing 22 is buckled into the first housing 21 , the hook 13 abuts against the rotating bracket 11 , and the first electrode end 121 and the second electrode end 122 are both in contact with the circuit contact point 231 of the mainboard 23 ;

[0041] When the second housing 22 is separated from the first housing 21 , the hook 13 drives the rotating bracket 11 to rotate, so that the first electrode end 121 and the second electrode end 122 are disconnected from the circuit contact point 231 of the mainboard 23 .

[0042] The security structure 1 provided in the present application can be applied to an electronic device 2. The security structure can monitor whether the electronic device has been disassembled and promptly detect any tampering with the electronic device. When the first shell 21 and the second shell 22 of the electronic device are fastened together, the two ends of the electrode of the security structure are in contact with the mainboard and are conductive, and the system of the electronic device detects the conductive signal. When the intruder separates the second shell from the first shell, the two ends of the electrode are disconnected from the mainboard, and the system of the electronic device detects the disconnect signal and records the event, such as the intrusion time. Therefore, the present application adopts a security structure to achieve the function of the current anti-tamper switch, and compared with the anti-tamper switch, the security structure of the present application is simple and convenient, easy to manufacture, and saves production costs.

[0043] For example, in this embodiment, the electronic device includes but is not limited to a laptop computer, a pad, a mobile phone, etc. Taking a laptop computer as an example, the first housing is the laptop computer's C component, and the second housing is the laptop computer's D component. When the C component and the D component are engaged, a chamber is formed. The security structure and the motherboard are installed in the chamber. The first electrode end and the second electrode end of the security structure's electrode are in contact with two circuit contact points on the motherboard. If an intruder lifts the D component, the D component drives the hook to detach from the C component, and the hook in turn drives the rotating bracket 11 to rotate, thereby disconnecting the first electrode end and the second electrode end from the circuit contact points of the motherboard. The laptop computer system detects a disconnection signal and records the event.

[0044] For example, in this embodiment, the rotating bracket 11 is made of insulating material, including but not limited to plastic, and the electrode 12 is made of conductive material, such as conductive material including but not limited to metal.

[0045] For example, further, Figure 6 As shown, the electrode 12 is a U-shaped structure, and the electrode 12 is embedded in the rotating bracket 11, and the first electrode end and the second electrode end are exposed on the surface of the rotating bracket 11. For example, the electrode 12 can be embedded in the rotating bracket 11 by hot pressing fusion, injection molding, etc.

[0046] For example, Figure 2 As shown, the main board 23 is provided with an escape opening 232 for evading the hook 13. When the first shell and the second shell are engaged, the hook 13 is accommodated in the escape opening 232. The hook 13 is arranged away from the rotation connection position between the rotating bracket and the first shell.

[0047] In some embodiments, as Figure 2 、 Figure 7As shown, the safety structure 1 of the present application also includes a pressing piece 14, which is arranged on the surface of the second shell 22 and extends toward the rotating bracket 11. When the second shell 22 is buckled into the first shell 21, the pressing piece 14 presses against the surface of the rotating bracket 11.

[0048] For example, in order to keep the rotating bracket 11 stable when the pressing member 14 is pressed against the surface of the rotating bracket 11, the pressing member 14 is positioned close to the electrode 12. Thus, when the first shell and the second shell are fastened together, the first electrode end and the second electrode end of the electrode can maintain contact and conduction with the circuit contact points of the mainboard.

[0049] When the first shell and the second shell are buckled together, the rotating bracket is in a horizontal state, and the first electrode end and the second electrode end at both ends of the electrode 12 are in contact with the circuit contact point of the motherboard. Therefore, in order to keep the rotating bracket stable and prevent the first electrode end and the second electrode end from separating or disconnecting from the circuit contact point of the motherboard when the electronic device falls or bumps, thereby causing system misjudgment, a pressing piece 14 extending toward the rotating bracket is provided on the surface of the second shell. The pressing piece 14 is a block structure, such as Figure 2 As shown, two pressing members 14 are provided, one on each side of the hook 13. When the first and second shells are engaged, the pressing members 14 can press against the surface of the rotating bracket in real time, ensuring that the first and second electrode ends of the electrodes maintain contact with the circuit of the mainboard in a conductive state, thus maintaining the stability of the rotating bracket and the circuit.

[0050] Furthermore, the hook 13, the pressing member 14 and the second housing 22 are connected as an integral structure. For example, the integral structure can be formed by injection molding, machining, etc. The integral structure is simple and convenient to manufacture and has high mechanical strength.

[0051] like Figure 7 As shown, when the first shell 21 and the second shell 22 are engaged, the hook 13 abuts against the rotating bracket 11. Furthermore, to facilitate the hook in rotating the rotating bracket, a slot 112 is provided along the length of the rotating bracket 11, near the hook, and the hook 13 engages with the slot 112. Furthermore, when the first and second shells are engaged, the hook 13 exerts a vertical pressure against the latch 111 of the rotating bracket, ensuring that when the second shell initially separates from the first shell, the hook simultaneously drives the rotating bracket to rotate.

[0052] In some embodiments, as Figure 2 As shown, the circuit contact point 231 is a slot provided on the mainboard 23 . When the second housing is buckled into the first housing, the first electrode end and the second electrode end are both snapped into the slot.

[0053] Of course, the circuit contact point 231 can also be a planar structure formed on the surface of the mainboard, for example, formed on the surface of the mainboard through surface mounting technology.

[0054] The circuit contact point 231 is a metal structure, and can establish signal conduction with the first electrode end, the second electrode end, and the mainboard.

[0055] In some embodiments, as Figure 3-4 As shown, the two ends of the rotating bracket 11 are provided with a rotating shaft 111, and the first shell 21 is provided with an axis hole 211 adapted to the rotating shaft. Figure 6 As shown, the rotating bracket 11 has a flat structure, with rotating shafts 111 extending outward from the left and right sides of the rotating bracket 11. Correspondingly, the first housing 21 has a shaft hole 211. The rotating shaft 111 is inserted into the shaft hole 211, thereby rotatably connecting the rotating bracket 11 to the first housing 21. The rotating bracket 11 can rotate within a range of 0 to 180 degrees via the rotating shaft 111 and the shaft hole 211.

[0056] For example, Figure 3 As shown, to facilitate installation of the rotating bracket, two mounting tabs 212 are formed extending outward from the surface of the first housing 21. The mounting tabs 212 are provided with shaft holes 211. The mounting tabs 212 have slight deformation and recovery capabilities. For example, the mounting tabs can be made of plastic or metal. When the rotating shaft 111 of the rotating bracket 11 is installed in the shaft hole 211, the mounting tabs 212 are slightly deformed by the rotating shaft 111. Once the rotating shaft 111 is inserted into the shaft hole 211, the mounting tabs 212 return to their original shape. This makes it easier to remove the rotating bracket from the first housing when it is necessary.

[0057] Therefore, the rotating bracket and the electrode of the safety structure 1 of the present application can be repeatedly disassembled from the first shell, which is simple, convenient and easy to assemble.

[0058] According to the second aspect of the present disclosure, Figure 1-2 As shown, the present invention also provides an electronic device 2, including a first shell 21, a second shell 22 and a mainboard 23, wherein the mainboard 23 is arranged in a cavity formed by the first shell and the second shell, and also includes a safety structure 1 in any one of the above embodiments.

[0059] The electronic device with the safety structure of the present application can also realize the function of the current anti-tamper switch. At the same time, the safety structure is simple and convenient, the structure is stable, not easy to fall, and cost is saved.

[0060] Taking a laptop as an example, the security structure is further explained in detail:

[0061] 1) Installation of safety structure 1:

[0062] 1) The laptop computer has a first shell (C), a second shell (D), and a motherboard. After the rotating bracket 11 and the electrode 12 are assembled, the two ends of the electrode 12 are exposed on the surface of the rotating bracket 11, and the middle part of the electrode 12 is embedded in the rotating bracket 11; the rotating shaft 111 of the rotating bracket 11 is vertically pressed into the shaft hole 211, thereby completing the assembly of the rotating bracket and the first shell.

[0063] 2) Then rotate the rotating bracket 11 so that it is parallel to the main board 23. At this time, the first electrode end and the second electrode end are inserted into the circuit contact points of the main board 23, and the circuit is now in a conducting state.

[0064] 3) Assemble the second housing onto the first housing, with the pressing piece 14 pressing tightly against the surface of the rotating bracket to stabilize the rotating bracket 11 and thus the circuit, while the hook abuts against the bayonet 112 of the rotating bracket.

[0065] 2) When the first shell and the second shell are in the locked state, Figure 8 As shown, the first electrode end and the second electrode end are in contact with the circuit contact point of the motherboard and are connected. At this time, the system of the laptop detects the conduction signal. Figure 9 As shown, when the second housing is opened, the second housing drives the latch, which in turn drives the swivel bracket to rotate synchronously, causing the first and second electrode ends of the electrodes to disengage from the circuit contact points on the motherboard, thereby disconnecting the circuit. The laptop's system then detects a disconnection signal and records the event, such as the disconnection time. If a circuit is disconnected between the electrode and the motherboard, simply rotating the second housing about 10° will suffice.
