Description

Technical Field

[0001] This application relates to the field of financial equipment structure technology, and further to an assembly component and a handheld financial device. Background Technology

[0002] Handheld financial devices are widely used in financial operations, making their security paramount. Existing tamper-evident flexible circuit boards (TEPCBs) prevent unauthorized disassembly, triggering an alarm once the casing is opened, thus ensuring device security. However, during drop tests before deployment, external impacts can cause internal components to slam, tearing the TPCB traces and triggering false alarms. This not only interferes with testers' assessment of the device's security performance but also affects normal use and user experience. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this application is to provide an assembly component and handheld financial device that can effectively avoid false alarms during drop tests, thereby ensuring the safety and reliability of the device.

[0004] To achieve the above objectives, this application provides an assembly component for the installation and assembly of handheld financial devices, comprising:

[0005] The assembly housing has an internal installation space for installing the tamper-proof flexible circuit board and screen assembly inside the handheld financial device. The tamper-proof flexible circuit board is connected to the screen assembly and the assembly housing, respectively.

[0006] The mating component is detachably connected to the assembly housing;

[0007] When the mating element is connected to the assembly housing, it is at least partially located within the mounting space, such that the tamper-proof flexible circuit board covers the outer periphery of the mating element during its installation; after the mating element is detached from the assembly housing, the tamper-proof flexible circuit board forms a partially raised redundant area through the mating element to provide the displacement of the tamper-proof flexible circuit board.

[0008] In some embodiments, the mating element includes an action segment and a handle, which are transitionally connected. When the mating element is connected to the assembly housing, the action segment is fixed to the mounting space to mate with the tamper-proof flexible circuit board to form the redundancy area, and the handle provides hand space for picking up or moving the mating element.

[0009] In some embodiments, there is at least one bend between the actuating segment and the handle, such that the trajectories of the actuating segment and the handle are not on the same straight line, thereby allowing the handle to be separated from the assembly housing by a predetermined distance to provide operating space.

[0010] In some embodiments, a first positioning structure is provided within the installation space, which can match a second positioning structure provided on the tamper-proof flexible circuit board to prevent the tamper-proof flexible circuit board from shifting relative to the assembly housing.

[0011] In some embodiments, the assembly housing is provided with a limiting groove that communicates with the installation space. When the mating element is connected to the assembly body, at least part of the actuating segment is embedded in the limiting groove to form a relative fixation between the mating element and the assembly housing.

[0012] In some embodiments, the mounting space includes a first mounting slot and a second mounting slot, the first mounting slot and the second mounting slot being connected, the first mounting slot being used to mount the tamper-proof flexible circuit board, and the second mounting slot being used to mount the screen assembly;

[0013] The limiting groove includes a first limiting groove and a second limiting groove. The first limiting groove and the second limiting groove are disposed on both sides of the first mounting groove along the width direction, so that both ends of the functional segment can be simultaneously embedded in the first limiting groove and the second limiting groove.

[0014] In some embodiments, the first limiting groove and the second limiting groove are arranged along the same straight line, and the first limiting groove is open on both sides in the straight line direction for the sliding of the working segment relative to the first limiting groove, so as to slide to install or remove the mating element.

[0015] The second limiting groove has a single-sided opening in the straight direction, and the opening direction of the second limiting groove faces the first limiting groove, in order to limit the sliding range of the active segment.

[0016] In some embodiments, the cross-sectional shape of the mating element is any one of a circle, a polygon, or an irregular shape.

[0017] Another aspect of this application also provides a handheld financial device, including: a main frame of the device, a power module, a screen assembly, and an anti-tamper flexible circuit board, wherein the power module is used to supply power to the handheld financial device;

[0018] The handheld financial device uses the aforementioned assembly components to assemble the tamper-proof flexible circuit board; wherein, the assembly housing of the assembly components is part of the main frame of the device, and together with other parts of the main frame of the device, constitutes the main structure of the handheld financial device, and the power module, the screen assembly, and the tamper-proof flexible circuit board are disposed within the main frame of the device.

[0019] In some embodiments, the screen assembly includes a relatively fixed screen backlight assembly and a touch unit, the screen backlight assembly being connected to the tamper-proof flexible circuit board, and the touch unit covering the side of the screen backlight assembly away from the tamper-proof flexible circuit board.

[0020] Compared with the prior art, the assembly components and handheld financial devices provided in this application have the following beneficial effects: By detachably connecting the mating components and the assembly housing, the tamper-proof flexible circuit board can form a partially raised redundant area after the mating components are disassembled, providing displacement for the tamper-proof flexible circuit board. This effectively solves the problem of tearing of the tamper-proof flexible circuit board traces caused by internal component impacts during drop tests or daily use of handheld financial devices, reduces false alarms, improves the reliability and safety of the device, and ensures that the device can better cope with external impacts while meeting safety protection requirements, thereby improving the overall performance of the device and the user experience.

[0036] In the financial sector, handheld financial devices play a crucial role, widely used in banking, securities, and insurance businesses to perform operations such as mobile payments, customer information inquiries, and transaction processing. With the development of financial services and increasing emphasis on information security, ensuring the security of handheld financial devices has become a critical issue.

[0037] To prevent criminals from stealing information or tampering with the functions of handheld financial devices by disassembling them, one existing solution is to install tamper-proof flexible circuit boards inside the devices. When the device is operating normally, the tamper-proof flexible circuit board can effectively detect whether the device has been illegally disassembled. Once the device casing is opened, the tamper-proof flexible circuit board will trigger an alarm mechanism, thus providing important physical security protection for the device.

[0038] However, before equipment is officially put into use, drop tests are usually required to ensure its quality and reliability. During drop tests, the equipment is subjected to external impact forces, which are transmitted to the internal components, causing relative movement and collisions. Since tamper-evident flexible circuit boards (TEPCBs) are typically connected to other components via traces, these traces can easily tear under impact. This tearing can cause false alarms, severely impacting the testing and production processes. On one hand, false alarms interfere with testers' judgment of the equipment's actual safety performance, preventing them from accurately assessing its tamper resistance under normal use. On the other hand, without effective measures, even if the equipment has not been illegally disassembled, accidental drops or minor collisions during daily use can trigger false alarms, affecting normal operation, causing inconvenience, and reducing user experience.

[0039] In one embodiment, refer to the appendix to the specification. Figure 1The present application describes an assembly component that can prevent the tamper-proof flexible circuit board 3 from accidentally cracking and causing false alarms when it is dropped or fell.

[0040] Reference manual attached Figures 1 to 3 The present application provides an assembly component including an assembly housing 1 and mating elements 2. The assembly housing 1 has a dedicated mounting space, providing an ideal installation environment for the tamper-proof flexible circuit board 3 and the screen assembly 4 within the handheld financial device. The tamper-proof flexible circuit board 3 is connected to both the screen assembly 4 and the assembly housing 1 within this mounting space.

[0041] More importantly, the mating component 2 is detachably connected to the mounting housing 1. Specifically, such as... Figure 2 , Figure 3 As shown, when the mating element 2 is connected to the assembly housing 1, it is at least partially located within the mounting space of the assembly housing 1, allowing the tamper-proof flexible circuit board 3 to cover the outer periphery of the mating element 2 during installation. When the mating element 2 is removed from the assembly housing 1, it causes the tamper-proof flexible circuit board 3 to form a partially protruding redundant area 31, which provides displacement for the tamper-proof flexible circuit board 3.

[0042] It is understandable that during drop tests or daily use, the equipment will inevitably be subjected to external impacts. The tamper-proof flexible circuit board 3 is often prone to tearing of the wiring due to the relative displacement of internal components, which may lead to false alarms.

[0043] This problem can be effectively solved by the redundant area 31 formed on the tamper-proof flexible circuit board 3 by this assembly. When the device is subjected to external impact, the tamper-proof flexible circuit board 3 can move and buffer to a certain extent using the displacement of the redundant area 31, thereby avoiding the stretching or tearing of the wiring caused by the instantaneous impact of internal components. For example, when a handheld financial device is accidentally dropped from a certain height, the tamper-proof flexible circuit board 3 can generate a certain displacement within the redundant area 31 under the action of the impact force, instead of bearing excessive stress due to rigid connections and layouts as in traditional designs. This protects the integrity of the wiring, significantly reduces the occurrence of false alarms, and greatly improves the reliability and safety of the device.

[0044] In actual operation, when assembling the tamper-proof flexible circuit board 3, first connect the mating component 2 to the assembly housing 1. Next, connect the two ends of the tamper-proof flexible circuit board 3, one end to the screen assembly 4 and the other end to the assembly housing 1. After the connection is completed, remove the mating component 2 from the assembly housing 1. At this time, a redundant area 31 will be generated at the original location of the mating component 2.

[0045] It should be noted that, in this embodiment, as Figure 4 As shown, the size of the redundancy area 31 depends on the outer perimeter of the mating element 2. During the design phase, the outer perimeter of the mating element 2 can be flexibly set according to factors such as the degree of impact that the handheld financial device may be subjected to, the material of the tamper-proof flexible circuit board 3, and the wiring layout, so as to precisely control the size of the redundancy area 31.

[0046] Furthermore, such as Figure 5 As shown, the mating element 2 includes an action section 21 and a handle 22, with a transition connection between the two sections. When the mating element 2 is connected to the assembly housing 1, the action section 21 is fixed within the mounting space of the assembly housing 1. During the assembly of the tamper-proof flexible circuit board 3, the tamper-proof flexible circuit board 3 covers the outer periphery of the action section 21. When the handle 22 subsequently removes the action section 21 from the assembly housing 1, the space originally occupied by the action section 21 is transformed into the redundant area 31 of the tamper-proof flexible circuit board 3.

[0047] The handle 22 is designed to provide a comfortable handhold for the operator, facilitating the handling and movement of the mating component 2. During the assembly of the handheld financial device, the operator can hold the handle 22 to accurately install the mating component 2 into the designated position on the assembly housing 1, or, after completing the connection of the tamper-proof flexible circuit board 3, conveniently remove the mating component 2 from the assembly housing 1 using the handle 22. Correspondingly, anti-slip textures or anti-slip materials can be provided on the surface of the handle 22 to ensure that the assembler can handle the mating component 2 more reliably and without slipping.

[0048] Optionally, based on this embodiment, positioning marks or protrusions can be provided on the surface of the actuating segment 21 to mate with corresponding grooves or marks on the inner wall of the assembly housing 1, ensuring that the position of the mating component 2 is precisely consistent each time it is installed, thereby ensuring the stability of the position and size of the redundant area 31 formed by the tamper-proof flexible circuit board 3. In addition, the actuating segment 21 and the handle 22 are connected by a smooth curve to avoid stress concentration and prevent damage to the mating component 2 due to uneven force during assembly or use.

[0049] In one embodiment, refer to Appendix Figure 5 At least one bent section 23 is provided between the actuating section 21 and the handle 22, which makes the trajectories of the actuating section 21 and the handle 22 not lie on the same straight line. When the mating element 2 is installed on the assembly housing 1, the handle 22 can be separated from the assembly housing 1 by a preset distance, thereby providing sufficient operating space for the operator.

[0050] Understandably, in the actual assembly scenario of handheld financial devices, the internal space is often extremely limited, and the components are arranged closely together. If the action section 21 and the handle 22 are on the same straight line, the handle 22 is likely to be too close to the assembly housing 1 or other internal components, making it difficult for the operator to grasp the handle 22 to perform the installation and disassembly operations of the mating element 2.

[0051] In this embodiment, the bending section 23 allows the handle 22 to be adjusted to a more easily operable position, maintaining a suitable distance from the assembly housing 1. This allows the operator to easily grip the handle 22 and accurately install the mating component 2 into the designated position on the assembly housing 1, completing the connection of the tamper-proof flexible circuit board 3. When disassembling the mating component 2, force can be applied more smoothly, avoiding misoperation due to insufficient operating space, such as damaging other internal components or causing the tamper-proof flexible circuit board 3 to loosen, thus ensuring the quality and stability of the equipment assembly.

[0052] Based on the content of this embodiment, the shape of the bending segment 23 can be flexibly designed according to actual needs. For example, as shown in the figure, the bending segment 23 forms a right angle with the action segment 21 and the handle 22, which can provide a larger operating space for the handle 22; in other embodiments, the bending segment 23 may also be designed with a certain curvature. Of course, the number of bending segments 23 can also be adjusted as needed. For equipment with complex internal space and high operating difficulty, multiple bends can be set to further optimize the operating position of the handle 22.

[0053] In one embodiment, such as Figure 1 , Figure 4 and Figure 6 As shown, a first positioning structure 11 is provided in the installation space, and a second positioning structure 32 is provided on the anti-tamper flexible circuit board 3 accordingly. The first positioning structure 11 and the second positioning structure 32 are matched.

[0054] When the tamper-proof flexible circuit board 3 is installed into the mounting space of the assembly housing 1, the first positioning structure 11 and the second positioning structure 32 cooperate and dock with each other, thereby effectively preventing the tamper-proof flexible circuit board 3 from shifting relative to the assembly housing 1.

[0055] First, the precise installation accuracy of the tamper-proof flexible circuit board 3 is greatly improved through the coordinated positioning structures in this embodiment. In traditional installation methods, the tamper-proof flexible circuit board 3 may shift in position within the assembly housing 1 due to human error or internal vibrations during installation. This solution, however, ensures that the tamper-proof flexible circuit board 3 is accurately installed in the preset position every time through precise matching of the positioning structures, significantly improving reliability and safety.

[0056] Secondly, it also enhances the stability of the equipment during use. Handheld financial devices may be subjected to various external forces during daily use, such as vibration and impact. If the tamper-proof flexible circuit board 3 is prone to displacement within the assembly housing 1, these external forces may cause its wiring to be pulled, increasing the risk of wiring tearing and thus triggering false alarms. Through the constraints of the first positioning structure 11 and the second positioning structure 32, the tamper-proof flexible circuit board 3 can maintain a stable position in various complex usage environments, effectively reducing the safety hazards caused by circuit board displacement and improving the reliability and safety of the equipment.

[0057] Optionally, the first positioning structure 11 can take various forms. For example, the first positioning structure 11 can be a protrusion set on the inner wall of the installation space, and the matching second positioning structure 32 can be a groove or hole opened on the edge of the tamper-proof flexible circuit board 3. The shape and size of the protrusion and the groove correspond precisely. During installation, the protrusion is embedded into the groove to achieve the positioning of the tamper-proof flexible circuit board 3. Alternatively, the first positioning structure 11 can be a positioning hole in the installation space, and the second positioning structure 32 can be a positioning pin on the tamper-proof flexible circuit board 3. During installation, the positioning pin is inserted into the positioning hole to prevent the circuit board from shifting.

[0058] In one embodiment, such as Figure 2 and Figure 3 As shown, the assembly housing 1 is provided with a limiting groove 12, which is connected to the installation space. When the mating element 2 is connected to the assembly body, at least part of the working section 21 of the mating element 2 can be embedded in the limiting groove 12, thereby achieving relative fixation between the mating element 2 and the assembly housing 1.

[0059] During the assembly of handheld financial devices, the devices may be subjected to external forces such as vibration and collision. If the connection between the mating component 2 and the assembly housing 1 is not secure enough, the mating component 2 may loosen or shift under these external forces, thereby affecting the position and function of the tamper-proof flexible circuit board 3 and also affecting the formation of the redundancy area 31. The setting of the limiting groove 12 allows the action section 21 to be embedded therein, effectively restricting the movement of the mating component 2 and ensuring the normal assembly of the tamper-proof flexible circuit board 3.

[0060] On the other hand, the limiting groove 12 provides a clear positional reference for the installation of the mating component 2. When installing the mating component 2, the operator only needs to align the actuating section 21 with the limiting groove 12 to achieve accurate positioning of the mating component 2. This not only reduces the assembly difficulty and installation deviations caused by human factors, but also ensures the consistency of each assembly, which is conducive to improving production efficiency and product quality.

[0061] It should be noted that the shape and size of the limiting groove 12 can be customized according to the shape and size of the active segment 21 of the mating element 2. For example, if the active segment 21 is rectangular, then the limiting groove 12 is also designed as a matching rectangular groove to ensure that the active segment 21 can be tightly embedded. At the same time, the depth of the limiting groove 12 can also be adjusted according to actual needs. If a stronger fixing effect is required, the depth of the limiting groove 12 can be appropriately increased so that most of the active segment 21 is embedded in it; if ease of disassembly is considered, a shallower limiting groove 12 can be selected, as long as the basic limiting function can be achieved.

[0062] In one embodiment, based on the content of the above embodiments, and referring to the appendix to the specification... Figure 6 and Figure 7 The installation space includes a first mounting slot 101 and a second mounting slot 102 that are connected to each other. The first mounting slot 101 is used to install the tamper-proof flexible circuit board 3, and the second mounting slot 102 is used to install the screen assembly 4. The first mounting slot 101 and the second mounting slot 102 are designed for the specific specifications of the tamper-proof flexible circuit board 3 and the screen assembly 4, respectively. This allows operators to easily place the corresponding components in the accurate positions during assembly, improving production efficiency and product quality consistency.

[0063] Meanwhile, the limiting groove 12 includes a first limiting groove 121 and a second limiting groove 122. These two limiting grooves 12 are distributed on both sides of the first mounting groove 101 along the width direction, so that both ends of the working section 21 of the mating element 2 can be simultaneously embedded therein. When the mating element 2 is installed, both ends of the working section 21 are embedded in the first limiting groove 121 and the second limiting groove 122 respectively. This double-sided limiting method greatly enhances the stability of the mating element 2 during the assembly process.

[0064] During the assembly process, both ends of the action section 21 are simultaneously fixed by the limiting groove 12, which effectively restricts the offset of the mating element 2. This not only ensures the accurate position of the mating element 2 during assembly, but also provides a stable benchmark for the subsequent installation of the anti-tamper flexible circuit board 3, preventing deviations in the installation of the anti-tamper flexible circuit board 3 due to the instability of the mating element 2, thereby affecting the overall performance of the equipment.

[0065] Furthermore, the first limiting groove 121 and the second limiting groove 122 are arranged along the same straight line. The first limiting groove 121 adopts a double-sided opening design in this straight line direction, providing a smooth sliding channel for the functional section 21 of the mating element 2. During the assembly process, the operator can slide the functional section 21 of the mating element 2 along the double-sided opening first limiting groove 121 to install the mating element 2; when it is necessary to remove the mating element 2, the functional section 21 can also be smoothly slid out through these double-sided openings, which greatly improves the convenience of assembly and disassembly, and the installation and removal of the mating element 2 can be completed without additional special tools.

[0066] In contrast, the second limiting groove 122 has a single-sided opening in the straight direction, and the opening direction faces the first limiting groove 121, which can limit the sliding range of the active segment 21. Referring to the attached drawings, when one end of the active segment 21 of the mating element 2 slides into the first limiting groove 121, it will continue to slide into the second limiting groove 122. Due to the single-sided opening of the second limiting groove 122, the sliding of the active segment 21 in this direction is limited to a certain range, thereby effectively preventing the mating element 2 from sliding excessively.

[0067] It should be noted that the double-sided openings of the first limiting groove 121 greatly improve assembly and disassembly efficiency. Compared with traditional assembly methods, the double-sided openings make the operation of mating components 2 more direct and efficient. Operators can quickly complete the assembly and disassembly of mating components 2 without the need for complex tools or cumbersome operations. In large-scale production, this can significantly shorten the assembly time of individual products and improve overall production efficiency.

[0068] Secondly, when the active section 21 slides into the second limiting groove 122, due to the obstruction of the opening on one side, the operator can intuitively perceive that the mating element 2 has reached the accurate installation position, which effectively avoids problems caused by improper assembly or over-assembly, and ensures the accuracy and consistency of each assembly.

[0069] Generally, the width of the first limiting groove 121 should be slightly larger than the width of the action section 21 to ensure that the action section 21 can slide smoothly, but it should not be too large to avoid the action section 21 wobbling in the groove; the depth of the second limiting groove 122 should be sufficient to accommodate the end of the action section 21. In addition, the opening edge of the limiting groove 12 can be set as a smooth chamfer to avoid scratching during the sliding of the action section 21.

[0070] In one embodiment, the cross-sectional shape of the mating element 2 is any one of a circle, a polygon, or an irregular shape. It is understood that mating elements 2 of different shapes each have significant advantages.

[0071] For the mating element 2 with a circular cross-section, its greatest advantage lies in its good rotational symmetry. For example, during assembly, regardless of the angle at which the active segment 21 of the mating element 2 is inserted into the limiting groove 12, the mating element 2 can be adjusted to the correct position through subsequent manual adjustment, which greatly improves the convenience of assembly; moreover, the tamper-proof flexible circuit board 3 can evenly cover the circumference, thereby forming a relatively regular and uniform redundant area 31.

[0072] Similarly, if the component 2 is set to a polygonal or irregular cross-section, the tamper-proof flexible circuit board 3 is laid out according to the shape of the polygon or irregular shape to form redundant areas 31 with different contours and lengths. Specifically, it can be set according to the actual situation and design requirements.

[0073] In one embodiment, according to another aspect of this application, this application further provides a handheld financial device, including a device main frame, a power module, a screen assembly 4, and an anti-tamper flexible circuit board 3.

[0074] It is worth noting that the handheld financial device in this application uses the aforementioned assembly components to mount the tamper-proof flexible circuit board 3. The assembly housing 1 of the assembly components is part of the main frame of the device and together with other parts of the main frame of the device, forms the main structure of the handheld financial device. The power module, screen assembly 4, and tamper-proof flexible circuit board 3 are disposed within the main frame of the device, wherein the power module is used to supply power to the handheld financial device.

[0075] The redundant area 31 formed on the tamper-proof flexible circuit board 3 by the assembly components enhances the security and reliability of handheld financial devices. When the handheld financial device encounters external impact or vibration, the tamper-proof flexible circuit board 3 can be appropriately displaced, thereby effectively buffering external forces and avoiding wire tearing caused by stress concentration. This design greatly reduces the risk of damage to the tamper-proof flexible circuit board 3 due to unexpected situations, which could lead to false alarms.

[0076] Based on the above, further, such as Figure 1 As shown, the screen assembly 4 includes a relatively fixed screen backlight assembly 41 and a touch unit 42. The screen backlight assembly 41 and the tamper-proof flexible circuit board 3 are connected to each other. The touch unit 42 covers the side of the screen backlight assembly 41 away from the tamper-proof flexible circuit board 3. The touch unit 42 faces the user directly and serves as a window for interaction between the device and the user.

[0077] Optionally, the touch unit 42 and the screen backlight assembly 41 are connected by foam adhesive. The foam adhesive has good adhesion and elasticity, which can firmly bond the touch unit 42 and the screen backlight assembly 41 together. Moreover, when the device is subjected to accidental collision or drop, the foam adhesive can absorb the impact force to a certain extent and reduce the direct damage to the touch unit 42 and the screen backlight assembly 41.

[0078] Understandably, the touch unit 42 in the screen assembly 4 needs to be completely fixed to the main frame of the device, with one side exposed to provide touch space, while the screen backlight assembly 41 is located inside the main frame of the device. Since there is usually a certain gap between the screen backlight assembly 41 and the main frame of the device, the screen backlight assembly 41 will shift due to inertia when the device is accidentally dropped. This displacement may cause the tamper-proof flexible circuit board 3 connected to the screen backlight assembly 41 to be pulled, which may lead to problems such as broken circuit board traces and loose connections. This not only affects the normal display function of the device, but may also trigger the tamper-proof mechanism, causing unnecessary false alarms.

[0079] At this time, by using component 2 to reserve a redundant area 31 for the tamper-proof flexible circuit board 3, when the screen backlight assembly 41 is displaced due to a drop and pulls the tamper-proof flexible circuit board 3, the redundant area 31 provides space for the circuit board to move, and the circuit board can move moderately, thereby buffering some of the pulling force and avoiding damage to the circuit due to stress concentration.

[0080] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application.
