Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment anti-disassembly, in particular to an electronic equipment. Background Art

[0002] Existing electronic devices such as POS machines and consumer tablets generally include components such as a front shell, display screen, motherboard, battery and back shell. The display screen, motherboard and battery are generally installed on the front shell, so the front shell is required to be strong enough to ensure that the components installed on the front shell can be securely fixed. As a result, the front shell has a certain thickness and weight, which is not conducive to reducing the weight and thickness of the electronic device.

[0003] In order to reduce the weight and thickness of electronic devices, some electronic devices adopt a flip-up display design, that is, the middle of the front shell is hollowed out, and most of the structural parts such as the motherboard and battery are installed on the back shell, and then the front shell assembly consisting of the display and the front shell is installed on the back shell. However, for financial products, it is also necessary to ensure the anti-dismantling of the display screen to prevent the financial products from being illegally disassembled and improve the safety of financial products. At present, the anti-dismantling of the display screen is generally to stick the MESH (anti-dismantling circuit) in the middle of the display screen, and the MESH is then connected to the motherboard through the zebra strip to prevent the display screen from being opened to attack the security devices on the motherboard. If financial products also adopt a flip-up display design and hollow out the middle of the front shell, the zebra strip will have no support position on the front shell, and it will be impossible to achieve a reliable connection between the zebra strip and the MESH, which will make the anti-dismantling of the display screen impossible, affecting the safety of financial products.

[0041] In addition, in the description of this application, ordinal numbers, such as "first", "second", etc., are only used to distinguish and describe related objects, and cannot be understood as indicating or implying the relative importance or order between related objects.

[0042] According to the embodiments provided in this application, Figure 1 As shown, an electronic device includes a front shell frame 100, a display screen 200, a back shell 300 and at least two anti-dismantling components 400, the front shell frame 100 includes a first corner portion 101 and a second corner portion 102 arranged diagonally; the display screen 200 is arranged on the front shell frame 100; one of the anti-dismantling components 400 is arranged at the first corner portion 101, and the other anti-dismantling component 400 is arranged at the second corner portion 102; the back shell 300 is fixedly connected to the front shell frame 100, and the anti-dismantling component 400 is clamped when the front shell frame 100 and the back shell 300 are connected.

[0043] Specifically, the front shell frame 100 is a frame structure formed by hollowing out the middle part of the front shell. The shape of the front shell frame 100 can be designed according to the appearance of the electronic device. By hollowing out the middle part of the front shell to form the front shell frame 100 and placing components such as the motherboard on the rear shell 300, the weight of the front shell can be reduced, making the entire device light and thin. The display screen 200 is mounted on the front shell frame 100. The front shell frame 100 corresponds to the black border area (BM area) on the display screen 200. The black border area on the display screen 200 is located at the edges of the display screen 200 and is used to block the light from the backlight panel to ensure that no light leaks from the edges when the screen is displayed, thereby improving the display effect of the display screen 200.

[0044] The front frame 100 includes a first corner 101 and a second corner 102, which are located on a diagonal line of the front frame 100. In this embodiment, when there are two anti-tampering components 400, the first anti-tampering component 400 is disposed at the first corner 101, and the second anti-tampering component 400 is disposed at the second corner 102. Each anti-tampering component 400 is connected to the front frame 100 in the same manner. In this embodiment, the two anti-tampering components 400 are disposed diagonally, so that no matter which corner of the front frame 100 is lifted from, the anti-tampering component 400 will be triggered to prevent the display screen 200 from being tampered.

[0045] The anti-dismantling component 400 is located at the corner of the front shell frame 100. When the rear shell 300 is fixedly connected to the front shell frame 100, the anti-dismantling component 400 is clamped so that one side of the anti-dismantling component 400 can be supported by the front shell frame 100, and the other side of the anti-dismantling component 400 can be supported by the rear shell 300 to ensure reliable connection between the various components in the anti-dismantling component 400, thereby realizing the anti-dismantling function.

[0046] In this embodiment, by hollowing out the middle of the front shell to form a front shell frame 100, the weight of the front shell and the weight of the entire machine can be reduced; by arranging two anti-dismantling components 400 on the diagonal line of the front shell frame 100, the anti-dismantling components 400 are supported and clamped by the front shell frame 100 and the rear shell 300, thereby ensuring reliable connection between the various components in the anti-dismantling components 400, realizing the anti-dismantling function, and meeting the anti-dismantling requirements of the display screen 200, thereby improving the safety of the entire machine.

[0047] In some embodiments, as Figure 2 and Figure 3 As shown, the anti-dismantling component 400 includes an anti-dismantling circuit board 410 and a zebra strip 420. The first area 411 of the anti-dismantling circuit board 410 abuts against the front shell frame 100. The second area 412 of the anti-dismantling circuit board 410 is attached to the display screen 200. The zebra strip 420 abuts against the first area 411 of the anti-dismantling circuit board 410. When the front shell frame 100 is connected to the rear shell 300, the zebra strip 420 and the first area 411 of the anti-dismantling circuit board 410 are clamped.

[0048] In this embodiment, each anti-tampering assembly 400 includes an anti-tampering circuit board (MESH) 410 and zebra strips 420. The anti-tampering circuit board 410 includes a first region 411 and a second region 412. The first region 411 of the anti-tampering circuit board 410 is connected to the zebra strips 420, while the second region 412 of the anti-tampering circuit board 410 is connected to the display screen 200. The first region 411 of the anti-tampering circuit board 410 is disposed on the front housing frame 100, while the second region 412 of the anti-tampering circuit board 410 is attached to the display screen 200. The second regions 412 of the two anti-tampering circuit boards 410 are also arranged diagonally on the display screen 200. If the display screen 200 is illegally disassembled, the second region 412 of the anti-tampering circuit board 410 is damaged, causing the circuit on the anti-tampering circuit board 410 to break, thereby triggering an alarm mechanism to prevent illegal disassembly.

[0049] The zebra strip 420 is arranged on the side of the anti-tampering circuit board 410 away from the display screen 200 and is connected to the first area 411 of the anti-tampering circuit board 410. One side of the zebra strip 420 is supported by the front shell frame 100. When the rear shell 300 is connected to the front shell frame 100, the other side of the zebra strip 420 is supported by the rear shell 300. After the rear shell 300 is fixedly connected to the front shell frame 100, the zebra strip 420 can be pressed tightly to ensure that the zebra strip 420 is in reliable contact with the anti-tampering circuit board 410, so as to avoid the zebra strip 420 and the anti-tampering circuit board 410 from failing to maintain reliable contact and triggering the alarm mechanism when the electronic device encounters situations such as falling or impacting during normal use. In this embodiment, the zebra strip 420 is clamped by the front shell frame 100 and the back shell 300 to achieve reliable contact between the zebra strip 420 and the anti-dismantling circuit board 410, which can prevent illegal disassembly of the electronic device from the direction of the back shell 300. When the back shell 300 is disassembled, the zebra strip 420 loses the pressing force of the back shell 300, making it impossible for the zebra strip 420 to maintain reliable contact with the anti-dismantling circuit board 410 and triggering the alarm mechanism to achieve the anti-dismantling function.

[0050] In some embodiments, as Figure 1 As shown, the front shell frame 100 includes a first side panel 110, a second side panel 120, a third side panel 130 and a fourth side panel 140 connected end to end in sequence, and the connection between the first side panel 110 and the second side panel 120 forms a first corner 101, and the connection between the third side panel 130 and the fourth side panel 140 forms a second corner 102.

[0051] The first area 411 of the anti-tamper circuit board 410 located at the first corner 101 abuts against the end of the first side panel 110 close to the second side panel 120, or the first area 411 of the anti-tamper circuit board 410 located at the first corner 101 abuts against the end of the second side panel 120 close to the first side panel 110. In other words, the first area 411 of the anti-tamper circuit board 410 located at the first corner 101 abuts against the first side panel 110 or the second side panel 120, and the zebra strip 420 is supported by the first side panel 110 or the second side panel 120 in the direction of the front housing frame 100.

[0052] The first area 411 of the anti-tamper circuit board 410 located at the second corner 102 abuts against an end of the third side panel 130 close to the fourth side panel 140, or the first area 411 of the anti-tamper circuit board 410 located at the second corner 102 abuts against an end of the fourth side panel 140 close to the third side panel 130. In other words, the first area 411 of the anti-tamper circuit board 410 located at the second corner 102 abuts against the third side panel 130 or the fourth side panel 140, and the zebra strip 420 is supported by the third side panel 130 or the fourth side panel 140 in the direction of the front shell frame 100.

[0053] Furthermore, the connection between the second side panel 120 and the third side panel 130 also forms the third corner 103 of the front shell frame 100 , and the connection between the fourth side panel 140 and the first side panel 110 also forms the fourth corner 104 of the front shell frame 100 .

[0054] In some embodiments, there are three anti-tampering components 400, with the first anti-tampering component 400 being disposed at the first corner 101 of the front frame 100, the second anti-tampering component 400 being disposed at the second corner 102 of the front frame 100, and the third anti-tampering component 400 being disposed at the third corner 103 of the front frame 100. Providing three anti-tampering components 400 can further enhance the anti-tampering performance of the electronic device, thereby further improving the safety of the electronic device.

[0055] In some embodiments, there are four anti-tampering components 400, a first anti-tampering component 400 being disposed at a first corner 101 of the front frame 100, a second anti-tampering component 400 being disposed at a second corner 102 of the front frame 100, a third anti-tampering component 400 being disposed at a third corner 103, and a fourth anti-tampering component 400 being disposed at a fourth corner 104. Disposing an anti-tampering component 400 at each corner of the front frame 100 can further improve the anti-tampering performance of the electronic device, thereby further improving the safety of use of the electronic device.

[0056] In some embodiments, as Figure 2 and Figure 3 As shown, screw holes 105 are respectively provided on the front shell frame 100 at the first corner 101 and the second corner 102. The first corner 101 and the second corner 102 of the front shell frame 100 are respectively fastened to the back shell 300 by the cooperation of screws and screw holes 105. The front shell frame 100 and the back shell 300 are fastened together by screws, which can provide sufficient fastening force for the zebra strip 420 to ensure the reliable connection between the zebra strip 420 and the anti-tamper circuit board 410. Of course, the front shell frame 100 and the back shell 300 can also be connected by other fastening structures, such as locks, buckles, etc., but it is necessary to ensure that the front shell frame 100 and the back shell 300 have sufficient pressing force to ensure the reliable connection between the zebra strip 420 and the anti-tamper circuit board 410. The third corner 103 and the fourth corner 104 of the front shell frame 100 can also be fixedly connected to the back shell 300 by screws.

[0057] In some embodiments, as Figure 1 As shown, it also includes a mainboard 500, which is arranged on the rear shell 300, and the zebra strip 420 is electrically connected to the mainboard 500. Figure 2 and Figure 4As shown, the anti-tamper assembly 400 also includes a zebra strip PCB 430, which is a circuit board that electrically connects the zebra strip 430 to the mainboard 500. The zebra strip 420 is abutted against the zebra strip PCB 430, and the zebra strip PCB 430 is electrically connected to the mainboard 500. In this embodiment, the zebra strip 420 is electrically connected to the mainboard 500 via the zebra strip PCB 430. Furthermore, the anti-tamper assembly 400 also includes an adapter FPC 440, which is a flexible circuit board that electrically connects the zebra strip PCB 430 to the mainboard 500. The zebra strip PCB 430 is electrically connected to the mainboard 500 via the adapter FPC 440, facilitating the arrangement of the zebra strip PCB 430 and the mainboard 500 within the electronic device.

[0058] In some embodiments, as Figure 5 As shown, the electronic device also includes a display FPC 600 and a connector 700. The display FPC 600 is a flexible circuit board that electrically connects the display 200 to the mainboard 500. One end of the display FPC 600 is electrically connected to the display 200, and the other end of the display FPC 600 is electrically connected to the mainboard 500 via the connector 700. The display 200 is fastened to the mainboard 500 via the connector 700. The connection between the display 200 and the mainboard 500 also forms a tamper-evident point, providing the display 200 with at least three tamper-evident points, thereby improving the safety of the electronic device.

[0059] In a specific embodiment, Figures 1 to 5 As shown, the LCD portion of the front shell frame 100 corresponding to the display screen 200 is hollowed out, the display screen 200 is glued to the front of the front shell frame 100, and the anti-disassembly circuit board 410 is attached to the diagonal position of the back of the front shell frame 100 to form a front shell assembly. The mainboard 500 is fixed on the back shell 300, the zebra strips 420 are patched on the zebra strip PCB430, and then the two zebra strip PCB430 are fixed to the diagonal positions of the back shell 300. The zebra strip PCB430 is connected to the mainboard 500 through the adapter FPC440 to form a back shell assembly. Finally, the front shell assembly is flipped into the back shell assembly, and the anti-disassembly circuit board 410 of the front shell assembly and the zebra strip 420 of the back shell assembly are conductively connected to the mainboard 500, and then the back shell 300 and the front shell frame 100 are locked by screws to ensure reliable contact between the zebra strip 420 and the anti-disassembly circuit board 410. The display screen FPC600 of the front shell assembly is connected to the main board 500 through the connector 700, so that the display screen 200 has at least 3 anti-dismantling points, meeting the anti-dismantling requirements of the display screen 200, and the weight of the front shell is greatly reduced. The thickness of the entire machine does not need to consider the thickness of the front shell wall, so the thickness of the entire machine is thinned.

[0060] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0061] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of the present application.
