Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to an anti-disassembly electronic display device and a mobile electronic terminal. Background Technology

[0002] In modern financial transactions, POS (Point of Sale) machines serve as crucial payment terminals, widely used in various commercial transaction scenarios. Traditional financial POS machines typically consist of multiple independent modules, including a Near Field Communication (NFC) module and a screen encryption and tamper-proof module. These two modules are functionally interdependent, jointly constructing a complete and secure financial transaction system.

[0003] In traditional financial POS machine designs, the near-field communication (NFC) module is typically integrated as a separate component on the back or side of the device. Specifically, the NFC coil is usually placed separately and connected to the mainboard via a flexible flat cable to communicate with the NFC chip. While this design achieves NFC functionality, it also has certain drawbacks. First, the independent layout of the NFC module occupies limited internal space within the POS machine, affecting the device's compactness and overall design. Furthermore, the separate design of the NFC module from the screen encryption and tamper-proof module increases the device's complexity and manufacturing cost. Utility Model Content

[0004] The purpose of this invention is to provide a tamper-proof electronic display device and mobile electronic terminal that effectively optimizes assembly space and reduces costs.

[0015] Compared with existing technologies, the anti-tamper electronic display device provided by the present invention achieves a high degree of integration between the near-field communication module and the display screen by embedding the near-field communication module within an insulating fastener between the display screen and the front shell. This design effectively saves limited internal space of the terminal device, improves the compactness and overall aesthetics of the device, and helps meet the demands of modern devices for thinness and lightness.

[0018] Figure 3This is a planar structural diagram of the NFC module in an embodiment of this utility model. Detailed Implementation

[0019] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] This embodiment discloses a mobile electronic terminal, such as a mobile phone or POS machine, which communicates with external devices based on a near-field communication module 6. The electronic terminal includes a base, on which an electronic display device is mounted. Figure 1 and Figure 2 The electronic display device includes a front shell 1 and a rear shell 2 disposed at the bottom of the front shell 1, and a display screen 3 is disposed on the side of the front shell 1 away from the rear shell 2.

[0021] There is an accommodating space K between the front shell 1 and the rear shell 2. The control motherboard 4 is installed in the accommodating space K, and the display screen 3 is electrically connected to the control motherboard 4. The display screen 3 is connected to the front shell 1 by a fastener 5 with insulating properties. A near-field communication module 6 is embedded in the fastener 5. The near-field communication module 6 is electrically connected to the control motherboard 4 through a connector 7.

[0022] The control motherboard 4 is also equipped with a safety protection module, which can control the working status of the safety protection module according to the connection status of the connector 7.

[0023] The electronic terminal in this embodiment can interact with external devices through the near-field communication module 6 and display interactive information on the display screen 3.

[0024] In addition, when the display screen 3 is removed, the connection between the connector 7 and the control motherboard 4 will inevitably be broken. In this way, the control motherboard 4 will control the safety protection module to enter the protection state, that is, the password protection state or the alarm state. Only when the user enters the correct password can the device be used again and the alarm be cleared.

[0025] In this embodiment, the near-field communication module 6 is embedded in the fastener 5 between the display screen 3 and the front shell 1, achieving a high degree of integration between the near-field communication module 6 and the display screen 3. This design effectively saves the limited space inside the electronic terminal, improves the compactness and overall aesthetics of the device, and helps meet the modern demand for thinner and lighter devices.

[0026] Secondly, a fastener 5 with excellent insulation properties is used to isolate the near-field communication module 6 from the display screen 3, reducing interference from the screen to the radio frequency signal, thereby ensuring the stability and reliability of the near-field communication module 6. This improvement ensures efficient operation of the electronic terminal in interaction with other devices and enhances the user experience.

[0027] Furthermore, electronic terminals with the aforementioned structure avoid the need to cut out a metal frame on the back of the display screen 3, thus maintaining the overall strength and structural integrity of the screen. At the same time, by limiting the choice of screen materials, the protective performance of the display screen 3 is ensured, reducing the risk of foreign objects entering and improving the stability and durability of the display effect.

[0028] Furthermore, the connector 7 between the near-field communication module 6 and the control motherboard 4 serves both as a data signal transmission and anti-tamper detection function, eliminating the need for a separate connector 7 for the anti-tamper mechanism, thus saving costs and space.

[0029] Furthermore, the integrated design allows for a tighter connection between the near-field communication module 6 and the control motherboard 4, with the connection status monitored by a security protection module. Once an abnormal connection is detected, the security protection module activates to prevent unauthorized disassembly and tampering, enhancing device security and protecting the security of financial transactions.

[0030] On the other hand, the fastener 5 is a double-layer foam adhesive, in which the near-field communication module 6 is clamped. This double-layer foam adhesive provides both bonding and insulation between the display screen 3 and the front housing 1, preventing the display screen 3 from interfering with the near-field communication module 6. Furthermore, the elasticity of the double-layer foam adhesive effectively reduces the assembly tolerance requirements between the display screen 3 and the front housing 1. It is worth noting that during the assembly process, the near-field communication module 6 can be supplied as part of the front housing 1 along with the double-layer foam adhesive, or it can be assembled with the double-layer foam adhesive and supplied together with the display screen 3.

[0031] Additionally, connector 7 is preferably an FPC flexible circuit board. Near Field Communication Module 6 includes an NFC module, such as... Figure 3 The NFC module is connected to the FPC flexible circuit board via conductive contact P.

[0032] The front cover 1 has a through hole through which the connector 7 passes to connect to the control motherboard 4, thus saving the length of the connector 7.

[0033] On the other hand, connector 7 is connected to the control motherboard 4 via zebra strip 8 to ensure the stability of signal transmission.

[0034] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
