[0002] With the rapid development of communication technology, new communication products are constantly emerging. These products often integrate advanced technology and innovative design, and have high market value. However, this also attracts the attention of peers, who may obtain technology and design inspiration through disassembly, research and imitation.

[0003] At present, the manufacturing technology of communication products is becoming more and more complex, and the internal structure of the products is becoming more and more sophisticated. This requires peers in the industry to have a certain level of technology and professional tools when disassembling and studying products. At the same time, some peers may use some means to cover up their disassembly and imitation behaviors, such as manually restoring the appearance of the product to make it difficult to distinguish from the surface. Summary of the invention

[0004] One purpose of the present application is to provide an anti-tampering alarm device and communication equipment, which at least solves the problem that current communication equipment is easy to disassemble and difficult to detect.

[0005] To achieve the above-mentioned purpose and other related purposes, in a first aspect, the present invention provides an anti-tampering alarm device, which is applied to a communication device, wherein the communication device includes an upper shell and a lower shell, and the alarm device includes:

[0006] A connecting block is disposed between the upper shell and the lower shell, and the connecting block includes:

[0007] A first connecting portion, fixedly connected to the upper shell;

[0008] a second connection portion connected to the first connection portion, and a breaking portion is provided between the first connection portion and the second connection portion, wherein the breaking stress of the breaking portion is lower than the breaking stress of the first connection portion or the second connection portion; and

[0009] A third connecting portion connected to the second connecting portion, and the third connecting portion is fixedly connected to the lower shell;

[0010] a trigger terminal, which is located between the upper housing and the lower housing, and the trigger terminal is communicatively connected to the alarm circuit of the communication device;

[0011] Wherein, when the upper shell and the lower shell are connected, the second connection part is connected to the trigger terminal, and the alarm circuit is connected; and when the breaking part is broken, the second connection part is separated from the trigger terminal, and the alarm circuit is disconnected and generates an alarm signal;

[0012] The intelligent identification module is used to generate disassembly information related to the communication device for local storage and remote transmission to a preset security server when receiving the alarm signal.

[0013] In one solution of the present invention, a first connecting seat is provided on the inner side of the upper shell, and the first connecting portion of the connecting block is detachably fixedly connected to the first connecting seat by screws.

[0014] In one solution of the present invention, a second connection seat is provided on the inner side of the upper shell, and a bottom connection seat is integrally formed on the lower shell, and the second connection seat and the bottom connection seat can be snap-fitted.

[0015] In one solution of the present invention, a limiting block is provided on the second connecting seat, and the limiting block can be clamped on the third connecting portion.

[0016] In one embodiment of the present invention, a protrusion is provided on the bottom connection seat, a notch is provided on the midline of the protrusion, and a connection hole is provided on the third connection portion of the connection block;

[0017] Wherein, the connection hole allows the protrusion to pass through and be clamped on the bottom connection seat.

[0018] In one embodiment of the present invention, the bottom connecting seat and the lower shell are integrally formed; the first connecting seat and the second connecting seat and the upper shell are integrally formed.

[0019] In one embodiment of the present invention, the first connection portion and the third connection portion are arranged in parallel.

[0020] In one embodiment of the present invention, the intelligent identification module includes:

[0021] A high-precision sensor is integrated and installed at the junction of the connection block, the upper shell and the lower shell, and is used to detect physical changes when the communication device is disassembled and send them to the processor for judgment;

[0022] a processor, which, when detecting that the physical change of the communication device when being disassembled exceeds a certain threshold, considers that the communication device may be disassembled and generates a high-priority warning signal; or considers that the communication device has been disassembled upon receiving the alarm signal, and outputs the warning signal or the alarm signal to the communication device;

[0023] An image acquisition unit, used to acquire current environment information according to the early warning signal or the alarm signal;

[0024] The wireless transmission module is used to send the disassembly information to a preset security server in a wireless manner, wherein the disassembly information includes the disassembly time, the disassembly location, the unique identification of the communication device and the environmental information.

[0025] In one solution of the present invention, the security server is used to automatically analyze the disassembly information and determine the legality of the disassembly behavior after receiving the early warning signal or the alarm signal. If the disassembly behavior is confirmed to be illegal, the device owner or the security team is allowed to remotely monitor the status, location and disassembly of the device in real time; and automatically start the multi-factor authentication mechanism, requiring the user to authenticate his identity to unlock the communication device. If the communication device is disassembled without authorization and cannot pass the multi-factor authentication, the device function is locked or sensitive data is erased.

[0026] In a second aspect, the present invention further provides a communication device, which includes the tamper-proof alarm device as described above.

[0027] Compared with the prior art, the present invention discloses an anti-tampering alarm device and communication equipment, which is connected to the alarm circuit through a connection block of a physical structure as a trigger key, and cleverly integrates it into the structure of the communication equipment. This design is not only simple and practical, but also can respond quickly when the equipment is maliciously disassembled. At the moment when the equipment is maliciously disassembled and the upper shell and the lower shell are opened, the broken part of the connection block will be damaged and broken. Without pressing the connection block, the switch of the trigger terminal pops out. This causes the electronic circuit in the circuit board to close, the anti-tampering alarm program to start, and trigger the corresponding alarm signal. This physical trigger mechanism has high reliability and stability and can play an important role at critical moments. Even if the equipment is assembled and restored, the brake switch cannot be pressed closed because the structure of the connection block has been destroyed. When the equipment is started, the anti-tampering alarm is identified and triggered. It can effectively improve the anti-dismantling effect of communication equipment during actual use.

[0028] The intelligent identification module further enhances the functionality and intelligence of the anti-tamper alarm device. The module uses high-precision sensors to monitor the physical changes of the device in real time, such as pressure, acceleration, displacement, etc., to determine whether the device is being disassembled. Once an abnormality is detected, the intelligent identification module will immediately generate an early warning signal and activate the corresponding alarm mechanism. In addition, the intelligent identification module can also communicate remotely with the security server and transmit the disassembly information to the server in real time for storage and analysis. This remote monitoring and alarm mechanism not only improves the safety of the device, but also allows the device owner or security team to understand the status of the device at the first time, so as to take corresponding countermeasures. The multi-level security protection mechanism further enhances the anti-tampering performance of the device.

[0029] In summary, the present invention realizes effective monitoring and alarming of malicious dismantling of communication equipment through physical triggering, real-time monitoring, remote alarm, safety protection and other technical means. This design not only improves the security and anti-tampering performance of the equipment, but also provides users with a more reliable and safe communication experience. Through the combination of physical mechanism, circuit warning and intelligent identification, the problem that current communication equipment is easy to dismantle and not easy to be detected can be effectively improved.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] See also Figures 1 to 11 The present invention discloses an anti-tampering alarm device and a communication device, which can be used to improve the problem that the current communication device is easy to be disassembled and not easy to be detected. Specifically, the anti-tampering alarm device disclosed in the present invention is applied to a communication device to prevent the communication device from being maliciously disassembled. It should be noted that the communication device is not limited to wired communication devices, wireless communication devices and others.

[0046] For example, wired communication equipment may be optical fiber transmission equipment, Ethernet switch, Ethernet switch, PCM (Pulse Code Modulation) equipment, etc. Wireless communication equipment may be wireless router, mobile communication base station, wireless walkie-talkie, Bluetooth headset, Bluetooth headset, wireless bridge, etc. And, other communication equipment may be optical module, communication base station cabinet, vehicle communication equipment, fax machine, modem, etc. However, it is not limited to this, and the communication equipment may be determined according to actual needs.

[0047] In some embodiments, the communication device at least includes an upper housing 100, a lower housing 400, and a circuit board 300 disposed between the upper housing 100 and the lower housing 400. A signal transmitting module is disposed on the circuit board 300, and the signal transmitting module can be used to establish a connection with an external client. The client can be used to receive signal information generated by the signal transmitting module.

[0048] Furthermore, an anti-tampering alarm device is provided in the communication device, and the anti-tampering alarm device at least includes a connection block 200 and a trigger terminal 310. The connection block 200 is provided between the upper housing 100 and the lower housing 400, and the connection block 200 is connected to the trigger terminal 310. The trigger terminal 310 is connected to an alarm circuit, and the trigger terminal 310 can allow the alarm circuit to be triggered when it is in a disconnected state.

[0049] Specifically, the connection block 200 includes a first connection portion 210, a second connection portion 220, and a third connection portion 230. The first connection portion 210 is fixedly connected to the upper housing 100, and the first connection portion 210 and the upper housing 100 may be detachably fixedly connected. For example, in some embodiments, a first connection seat 110 is provided on the inner side of the upper housing 100, and the first connection portion 210 of the connection block 200 is detachably fixedly connected to the first connection seat 110 by screws. By arranging the connection block 200 on the first connection seat 110, it is convenient to install the connection block 200.

[0050] The second connection part 220 is connected to the first connection part 210, and a breaking part 201 is provided between the first connection part 210 and the second connection part 220, and the breaking stress of the breaking part 201 is lower than the breaking stress of the first connection part 210 or the second connection part 220. When the upper shell 100 and the lower shell 400 are violently disassembled, the breaking part 201 breaks with the first connection part 210 and the second connection part 220 first, so that the first connection part 210 and the second connection part 220 are separated.

[0051] The third connection portion 230 is connected to the second connection portion 220 , and the third connection portion 230 is fixedly connected to the lower housing 400 .

[0052] Specifically, it is allowed to set a bottom connection seat 410 on the lower shell 400, and a protrusion 411 is set at the end of the bottom connection seat 410. A notch is opened on the center line of the protrusion 411, and a connection hole is opened on the third connection part 230 of the connection block 200. Therefore, the connection hole can be allowed to pass through the protrusion 411 and be clamped on the bottom connection seat 410.

[0053] At the same time, in order to improve the connection effect between the upper shell 100 and the lower shell 400 of the device. It is also allowed to set a second connection seat 120 on the inner side of the upper shell 100, and the second connection seat 120 and the bottom connection seat 410 can be snapped together. By snapping the second connection seat 120 with the bottom connection seat 410, the stability between the upper shell 100 and the lower shell 400 during the connection process is improved. At the same time, the protrusion 411 located on the bottom connection seat 410 can be snapped into the second connection seat 120, so when the third connection part 230 is snapped on the bottom connection seat 410, the second connection seat 120 can press the third connection part 230 on the bottom connection seat 410.

[0054] In order to improve the actual connection effect of the connection block 200 of the present device, it is allowed to set a limit block 121 on the second connection seat 120. The limit block 121 includes two groups, and the two groups of limit blocks 121 are symmetrically arranged. Therefore, the two symmetrically arranged limit blocks 121 can be clamped on the edge of the third connection portion 230 of the connection block 200, thereby improving the stability of the connection block 200 during the connection process.

[0055] It should be noted that when the upper housing 100 and the lower housing 400 are connected, the second connection portion 220 is connected to the trigger terminal 310, and the alarm circuit is connected. When the breaking portion 201 is broken, the second connection portion 220 is separated from the trigger terminal 310, and the alarm circuit is disconnected and generates an alarm signal.

[0056] Furthermore, the anti-tamper alarm device also includes an intelligent identification module, which is used to generate disassembly information related to the communication device for local storage and remote transmission to a preset security server when an alarm signal is received. Therefore, after receiving the alarm information, the security server can automatically send a notification to the device owner or security team and provide a detailed report of the disassembly event, further improving the anti-tamper performance and the security of the device.

[0057] Further, in some embodiments, the bottom connection base 410 and the lower shell 400 are integrally formed, and the first connection portion 210 and the third connection portion 230 are arranged in parallel. By arranging the bottom connection base 410 and the lower shell 400 to be integrally formed, the connection strength between the bottom connection base 410 and the lower shell 400 can be effectively improved. At the same time, by arranging the first connection portion 210 and the third connection portion 230 to be arranged in parallel, the strength of the connection block 200 can be improved, and the first connection portion 210 and the second connection portion 220 can be easily broken at the breaking portion 201.

[0058] As described above, the first connection base 110 and the second connection base 120 are integrally formed with the upper housing 100 to improve the connection strength between the first connection base 110 and the second connection base 120 and the upper housing 100 respectively.

[0059] Furthermore, the communication device disclosed in the present invention further includes a circuit board 300 . It can be understood that the trigger terminal 310 is fixedly connected to the circuit board 300 .

[0060] The present invention also discloses a communication device, and the product includes the anti-tampering alarm device disclosed in the above embodiment.

[0061] Based on this, the tamper-proof alarm device and communication equipment disclosed in the present invention may include the following steps during actual use.

[0062] First, the connection block 200 is fixed to the upper shell of the device by screws or buckles to ensure that its structure is firm. Secondly, the circuit board 300 is fixed to the lower shell 400 of the device by screws or buckles to ensure that its structure is firm. In this state, the trigger terminal 310 pops up and closes, and the electronic circuit in the circuit board 300 is closed, completing the anti-tampering alarm program identification and burning.

[0063] Furthermore, the connection block 200 is positioned opposite to the trigger terminal 310 of the electronic circuit in the circuit board 300, and in particular, the connection block 200 must be positioned opposite to the brake button. The assembled upper shell 100 and lower shell 400 are buckled up and down through the preset guide structure, at which time the connection block 200 is facing the trigger terminal 310 on the circuit board 300, and the upper and lower shells are assembled using screws and hooks.

[0064] At this time, the trigger terminal 310 is pressed open, and the electronic circuit in the circuit board 300 is disconnected. The preset anti-tampering alarm software program waits to recognize the low power start, and the connecting block 200 is tightly combined and fixed with the upper and lower shells.

[0065] When the device is assembled and the hardware is burned, the software starts and runs normally.

[0066] It should be noted that when the device is maliciously disassembled, the moment the upper shell 100 and the lower shell 400 are opened, the breaking portion 201 of the connecting block 200 will be damaged and broken, and without the pressing of the connecting block 200, the switch of the trigger terminal 310 will pop out. The electronic circuit in the circuit board 300 is closed, the anti-tampering alarm program is activated, and the corresponding alarm signal is triggered.

[0067] It is understandable that even if the device is assembled and restored, the brake switch cannot be pressed closed because the structure of the connecting block 200 has been destroyed. When the device is started, the anti-tamper alarm is identified and triggered.

[0068] In some embodiments, the smart identification module includes:

[0069] High-precision sensors, which may include pressure sensors, acceleration sensors, displacement sensors, etc., are integrated and installed at the joint of the connection block 200, the upper shell 100, and the lower shell 400, and are used to detect physical changes when the communication device is disassembled and send them to the processor for judgment, so as to achieve accurate identification of the disassembly event;

[0070] The processor, when detecting that the physical changes of the communication device when being disassembled exceed a certain threshold, considers that the communication device may be disassembled and generates a high-priority early warning signal; or considers that the communication device has been disassembled when receiving an alarm signal, and outputs the early warning signal or alarm signal to the communication device. Optionally, the communication device can activate its internal alarm mechanism, such as sounding an alarm, lighting an indicator light, etc.

[0071] The environment collection unit may be a camera of the communication device or a miniature camera integrated in a suitable position of the communication device (such as an internal or external hidden place), and at least one of a light sensor and a sound sensor, etc., for collecting current environment information according to the early warning signal or the alarm signal;

[0072] The wireless transmission module is used to send alarm information to the security server wirelessly (such as Bluetooth, Wi-Fi or 4G / 5G) to ensure the timely transmission of information. The disassembly information includes the disassembly time, disassembly location, unique identification of the communication equipment and environmental information.

[0073] Furthermore, the security server is used to automatically analyze the disassembly information and determine the legality of the disassembly behavior after receiving the early warning signal or the alarm signal. If the disassembly behavior is confirmed to be illegal, the device owner or the security team is allowed to remotely monitor the status, location and disassembly of the device in real time; and automatically start the multi-factor authentication mechanism (such as passwords, fingerprints, facial recognition and other mechanisms to ensure that only authorized users can access or modify the device), requiring the user to authenticate to unlock their communication device. If the communication device is disassembled without authorization and cannot pass the multi-factor authentication, the device function is locked or sensitive data is erased.

[0074] Through the above embodiments, the intelligent recognition module further improves the functionality and intelligence level of the anti-tampering alarm device. The module monitors the physical changes of the device in real time through high-precision sensors, such as pressure, acceleration, displacement, etc., to determine whether the device is being disassembled. Once an abnormality is detected, the intelligent recognition module will immediately generate an early warning signal and start the corresponding alarm mechanism. At the same time, the module can also collect current environmental information, such as images, sounds, etc., to provide an important basis for subsequent security analysis and processing. The intelligent recognition module can monitor and record the disassembly history of the communication device in real time, including the time, location and detailed process of each disassembly, and can provide a detailed report of the disassembly event to the security server, including the identity characteristics of the disassembler (if captured), disassembly time, disassembly location and video or picture evidence of the disassembly process, etc., and when the communication device is disassembled without authorization and cannot pass multi-factor authentication, the device function is locked or sensitive data is erased, which is convenient for users and security teams to understand the security status of the device in a timely manner and take corresponding preventive measures, which greatly improves user satisfaction and trust, as well as improves the security and tamper-proof of the communication device. Remote monitoring and alarm mechanisms not only improve the security of the device, but also allow the device owner or security team to understand the status of the device in the first place, so that they can take corresponding countermeasures. This multi-level security protection mechanism further enhances the device's anti-tampering performance.

[0075] In summary, the present invention discloses an anti-tampering alarm device and communication equipment, which is connected to the alarm circuit through a connection block 200 of a physical structure as a trigger key. When the device is maliciously disassembled and the upper shell 100 and the lower shell 400 are opened, the breaking portion 201 of the connection block 200 will be damaged and broken. Without the pressing of the connection block 200, the switch of the trigger terminal 310 pops out. As a result, the electronic circuit in the circuit board 300 is closed, the anti-tampering alarm program is started, and the corresponding alarm signal is triggered. Even if the device is assembled and restored, the brake switch cannot be pressed and closed because the structure of the connection block 200 has been destroyed. When the device is started, the anti-tampering alarm is identified and triggered. It can effectively improve the anti-dismantling effect of communication equipment during actual use. Through the combination of physical mechanism, circuit warning and intelligent recognition, the problem that current communication equipment is easy to disassemble and not easy to be unnoticed can be effectively improved.

[0076] Therefore, the present invention effectively overcomes some practical problems in the prior art and thus has high utilization value and use significance.
