Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and in particular to an anti-theft and anti-tampering structure and electronic equipment. Background Technology

[0002] To prevent users from disassembling existing electronic devices, such as laptops and tablets, and causing product malfunctions, manufacturers typically employ the following three protective measures:

[0003] Method 1: Set up anti-counterfeiting features. Use anti-counterfeiting or fragile stickers and affix them to the screw heads, above the screw holes, or at the interface where the upper and lower shells are separated. Once the user opens the casing, the sticker will be destroyed.

[0004] Method two involves setting up anti-theft and tamper-proof structures, using less common screw heads, or methods that require special tools to open the casing, to prevent users from disassembling and assembling the product themselves.

[0005] Method 3: Install an anti-theft and tamper switch to detect and record whether the device has been tampered with.

[0006] However, for method one, the fragile sticker has a small adhesive area and is not firmly attached, making it easy to remove without damage; for method two, the anti-theft structure is simple and lacks an alarm function, failing to effectively protect the data inside the electronic product; for method three, the anti-theft switch can be easily bypassed by inserting a card, leading to risks such as information leakage and data theft. Summary of the Invention

[0007] In view of this, according to one aspect of the present invention, an anti-theft and tamper-proof structure is provided to at least partially solve the above-mentioned technical problems.

[0008] An anti-theft and tampering structure of the present invention includes a first housing, a second housing, a main board, and a triggering component. The first housing and the second housing are detachably connected and a receiving space is formed between them. The main board is disposed in the receiving space and an alarm circuit is provided on the main board. The triggering component includes a driven member and a contact member.

[0009] The driven member is connected to the first housing. When the first housing is detached from the second housing, the driven member moves with the first housing relative to the second housing between a first position and a second position.

[0010] The contact is disposed on the alarm circuit. When the driven member is in the first position, it is away from the contact to disconnect the alarm circuit; when the driven member is in the second position, it abuts against the contact to turn on the alarm circuit.

[0011] Alternatively, the contact includes a positive contact area and a negative contact area, with a gap between the positive contact area and the negative contact area, and the positive contact area and the negative contact area are connected through the follower when the follower is in the second position.

[0012] Alternatively, the driven member has a first connecting portion and a second connecting portion, the first connecting portion being fastened to the second housing, and when the first housing is removed from the second housing, the second connecting portion rotates about the first connecting portion to move relative to the second housing between a first position and a second position.

[0013] Alternatively, the first housing has a hook portion formed within the accommodating space, and the follower has a locking portion formed between the first connecting portion and the second connecting portion, the hook portion being connected to the locking portion so that the second connecting portion rotates around the first connecting portion when the first housing is removed from the second housing.

[0014] Optionally, the snap-fit ​​portion has a through hole; the first housing has an inner surface located within the accommodating space, an extension portion extending from the inner surface toward the second housing, the snap hook portion is formed on the end of the extension portion away from the inner surface, and the snap hook portion passes through the through hole and hooks onto the snap-fit ​​portion.

[0015] Alternatively, the second connection portion includes a first branch and a second branch, both of which extend from the end of the snap-fit ​​portion away from the first connection portion. The first branch is used to abut against the positive electrode contact area, and the second branch is used to abut against the negative electrode contact area.

[0016] Alternatively, the driven member may be an elastic member.

[0017] Alternatively, the motherboard may include a storage module for storing the activation signal of the alarm circuit.

[0018] Alternatively, the motherboard may include a communication module for transmitting the conduction signal of the alarm circuit to a cloud server for storage.

[0019] According to another aspect of the present invention, an electronic device is also provided, including a first housing, a second housing, a motherboard, and an anti-theft and tamper structure, wherein the first housing and the second housing are detachably connected by the anti-theft and tamper structure and an accommodating space is formed between them, the motherboard is disposed in the accommodating space, and the anti-theft and tamper structure includes an alarm circuit and a triggering component, wherein the alarm circuit is disposed on the motherboard, and the triggering component includes a follower and a contact.

[0020] The driven member is connected to the first housing. When the first housing is detached from the second housing, the driven member moves with the first housing relative to the second housing between a first position and a second position.

[0021] The contact is disposed on the alarm circuit. When the driven member is in the first position, it is away from the contact to disconnect the alarm circuit; when the driven member is in the second position, it abuts against the contact to turn on the alarm circuit.

[0022] In this invention, based on the alarm circuit and the triggering component including the driven member and the contact member, when the first housing is removed from the second housing, the alarm circuit can be turned on or off by changing the position of the driven member, so as to detect that the electronic device has been disassembled, and avoid the risk of being deceived by inserting a card.

[0032] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] The anti-theft and tamper-proof structure of the present invention is mainly used in electronic devices, which may be laptops, tablets, or other terminal devices with motherboards.

[0035] like Figures 1 to 3 As shown, the anti-theft and tamper-proof structure of the present invention includes a first housing 110, a second housing 120, a main board 130, and a trigger assembly 140. The first housing 110 and the second housing 120 are detachably connected, and an accommodating space (not marked in the diagram) is formed between them. The main board 130 is disposed within the accommodating space, and an alarm circuit (not shown in the diagram) is disposed on the main board 130. The trigger assembly 140 includes a follower 141 and a contact 142. The follower 141 is connected to the first housing 110. When the first housing 110 is detached from the second housing 120, the follower 141 moves with the first housing 110 relative to the second housing 120 between a first position and a second position. The contact 142 is disposed on the alarm circuit. When the follower 141 is in the first position, it moves away from the contact 142 to disconnect the alarm circuit; when the follower 141 is in the second position, it abuts against the contact 142 to turn on the alarm circuit. Here, the first position is any position within the accommodating space where the driven member 141 and the contact member 142 are far apart, and the second position is any position within the accommodating space where the driven member 141 and the contact member 142 are in contact.

[0036] It should be understood that when the anti-tamper structure is applied to a laptop, the first housing 110 can be the bottom housing, and the second housing 120 can be the keyboard housing. When the anti-tamper structure is applied to a tablet, the first housing 110 can be the bottom housing, and the second housing 120 can be the screen housing.

[0037] In this invention, based on the alarm circuit and the trigger assembly 140 including the follower 141 and the contact 142, when the first housing 110 is removed from the second housing 120, the alarm circuit can be turned on by changing the position of the follower 141, so as to detect that the electronic device has been disassembled. Furthermore, the alarm circuit can be turned on or off by the follower 141 moving away from or abutting the contact 142, thus avoiding the risk of being deceived by inserting a card.

[0038] As not shown, in an embodiment of the present invention, the motherboard 130 may include a storage module connected to an alarm circuit for storing the alarm circuit's activation signal. Thus, even if the electronic device is disassembled and reassembled, it can be detected by checking the information stored in the storage module, which helps improve anti-tampering performance and facilitates subsequent tracing to detect disassembly in a timely manner.

[0039] As not shown, in an embodiment of the present invention, the motherboard 130 may include a communication module connected to an alarm circuit, which is used to transmit the conduction signal of the alarm circuit to a cloud server for storage. In this way, when the electronic device is disassembled, even if it is reassembled, it can be detected by viewing the information stored on the cloud server, which helps to improve the anti-tampering performance and facilitates subsequent tracing to detect disassembly in a timely manner. This also makes it easier to track product quality and prevent counterfeit products.

[0040] See again Figure 3 In one embodiment of the present invention, the contact 142 includes a positive contact area 1421 and a negative contact area 1422, with a gap between them. When the driven member 141 is in the second position, the positive contact area 1421 and the negative contact area 1422 are connected through the driven member 141. Thus, by configuring the positive contact area 1421 and the negative contact area 1422, the contact 142 and the driven member 141 form a switch for the alarm circuit. When the driven member 141 is in the first position, the switch is open and the alarm circuit is not connected. When the driven member 141 is in the second position, the switch is open and the alarm circuit is connected.

[0041] See also Figure 2 , Figure 4 and Figure 5In one embodiment of the present invention, the driven member 141 has a first connecting portion 1411 and a second connecting portion 1412. The first connecting portion 1411 is fastened to the second housing 120. When the first housing 110 is removed from the second housing 120, the second connecting portion 1412 rotates about the first connecting portion 1411 to move relative to the second housing 120 between a first position and a second position. In this way, the driven member 141 is partially fixed and partially connected to the first housing 110, so that when the first housing 110 is removed from the second housing 120, the driven member 141 rotates between the first position and the second position, and the driven member 141 can be easily driven when the first housing 110 is removed. Here, the fastener may include a positioning post 121 disposed on the second housing 120. Specifically, the second housing 120 has a first surface 1201 located within the accommodating space. The positioning post 121 protrudes from the first surface 1201. A connecting hole 14111 may be provided on the first connecting portion 14111. Through the cooperation of the positioning post 121 and the connecting hole 14111, the first connecting portion 1411 and the second housing 120 can be fixedly connected. It should be understood that the fastener may also be a common screw, bolt, etc., as long as it can achieve the purpose of fixing the first connecting portion 1411 to the second housing 120.

[0042] See also Figure 2 and Figure 5 In order to drive the driven member 141 when the first housing 110 is disassembled, the first housing 110 has a hook portion 111 formed in the accommodating space, and the driven member 141 has a locking portion 1413 formed between the first connecting portion 1411 and the second connecting portion 1412. The hook portion 111 and the locking portion 1413 are connected so that when the first housing 110 is disassembled from the second housing 120, the second connecting portion 1412 rotates around the first connecting portion 1411.

[0043] Furthermore, a through hole 14131 is provided on the latching portion 1413. Correspondingly, the first housing 110 has an inner surface 1101 located within the accommodating space. An extension portion 112 extends from the inner surface 1101 toward the second housing 120. A hook portion 111 is formed on the end of the extension portion 112 away from the inner surface 1101, and the hook portion 111 passes through the through hole 14131 and hooks against the latching portion 1413. In this way, the entire trigger assembly 140 is located within the accommodating space, avoiding the problem of the trigger assembly 140 being exposed, which would affect the overall shape of the electronic device.

[0044] It should be understood that the connection between the driven member 141 and the first housing 110 is not limited to the above-mentioned connection method. A snap-fit ​​structure can also be used for connection, as long as the driven member 141 can be driven when the first housing 110 is disassembled.

[0045] See also Figure 3 and see Figure 5 In one embodiment of the present invention, in order to ensure that the driven member 141 can reliably abut against the contact member when it is in the second position, so as to achieve the purpose of conducting the alarm circuit, the second connecting part 1412 includes a first branch 14121 and a second branch 14122. The first branch 14121 and the second branch 14122 both extend from the end of the snap-fit ​​part 1413 away from the first connecting part 1411. The first branch 14121 is used to abut against the positive electrode contact area 1421, and the second branch 14122 is used to abut against the negative electrode contact area 1422.

[0046] In one embodiment of the present invention, the follower 141 is an elastic member, thereby avoiding the problem that the follower 141 is easily damaged during disassembly.

[0047] According to another aspect of the present invention, an electronic device is also provided, including a first housing 110, a second housing 120, a motherboard 130, and an anti-theft and tamper-proof structure. The first housing 110 and the second housing 120 are detachably connected by the anti-theft and tamper-proof structure, and an accommodating space is formed between them. The motherboard 130 is disposed in the accommodating space. The anti-theft and tamper-proof structure includes an alarm circuit and a triggering component 140. The alarm circuit is disposed on the motherboard 130. The triggering component 140 includes a follower 141 and a contact 142. The follower 141 is connected to the first housing 110. When the first housing 110 is detached from the second housing 120, the follower 141 moves with the first housing 110 relative to the second housing 120 between a first position and a second position. The contact 142 is disposed on the alarm circuit. When the follower 141 is in the first position, it moves away from the contact 142 to disconnect the alarm circuit. When the follower 141 is in the second position, it abuts against the contact 142 to turn on the alarm circuit.

[0048] When the electronic device is in its complete state (i.e., without being disassembled), the driven member 141 is in the first position, away from the contact member 142 to disconnect the alarm circuit. When the electronic device is disassembled, since disassembly requires removing the first housing 110 from the second housing 120, the driven member 141 will be moved to the second position, thereby abutting against the contact member 142 to turn on the alarm circuit.

[0049] Applying an anti-theft and tamper-proof structure to detachably connect the first housing 110 and the second housing 120 on electronic devices can not only improve the aesthetics of electronic products, but also detect whether the electronic device has been disassembled, thus avoiding the risk of being tricked by inserting cards.
