Abstract
Description
Technical Field
[0001] This utility model relates to the field of security equipment technology, and in particular to a security anti-peeping structure for bank self-service terminals. Background Technology
[0002] A bank account opening self-service terminal refers to equipment provided by banks for customers to handle account opening business independently. The self-service terminal offers various modes, and individual customers can use it to conduct inquiries, transfers, payments, passbook updates, print statements, and access financial information, among other services.
[0003] In the course of service processing, financial transactions are inevitable, which requires consumers to enter payment passwords. Generally, self-service terminals have privacy screens installed on the outside of the password keys. The top area of the screen has 3-5 rows of louvered observation holes arranged in a gradient. Each observation hole is precisely arranged at a 45° angle to form a specific optical path. When the user enters the password in a normal operating posture (the body axis is at an angle of 30-40° with the device), the key numbers can be clearly identified through the limited field of view formed by the Fresnel lens principle. However, because the observer is at a non-direct angle (usually more than 15° off the axis), their line of sight will be completely blocked by the multi-layer light shield of the louvered structure, effectively preventing peeping from the side and rear.
[0004] Existing privacy screens generally adopt an open front design. While this ensures the user's arm can be freely inserted and their operational flexibility is maintained, it introduces new security risks. However, actual test data shows that in a standard bank counter scenario (the distance between the user and the people queuing behind is about 80-100cm), an observer in a 135° fan-shaped area to the side and rear can form an effective viewing angle of about 12° through the opening. Especially when users are entering complex passwords (such as 6-digit passwords that require continuous operation), about 23% of the input actions will expose some key information due to finger movement. More concerning is that in recent years, in cases of "shoulder peeping," some people often use miniature wide-angle cameras (such as 3mm diameter 1080P pinhole devices) with telephoto lenses to capture 82% of keystrokes through the privacy screen opening at a distance of 1.5 meters, thereby reading the consumer's password, which is quite insecure. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a secure anti-peeping structure for bank self-service terminals.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a secure anti-peeping structure for a bank self-service terminal, comprising a terminal body, a display screen at the top of the terminal body, a card slot, an input keyboard, a printer port, and a reader sequentially arranged on the surface of the terminal body, an anti-peeping cover fixed to the surface of the input keyboard, louvers arranged in an array at the top of the anti-peeping cover, the louvers being inclined, a lead screw connected to a bearing in the internal cavity of the terminal body, a slide block threaded to both ends of the lead screw, and an anti-peeping groove formed on the surface of the terminal body, the slide block being slidably connected to the anti-peeping groove, a first anti-peeping plate and a second anti-peeping plate detachably connected to the top of the slide blocks at both ends, the surfaces of the first and second anti-peeping plates being arc-shaped grooves, and the internal thread grooves of the slide blocks at both ends being opposite in direction, the lead screw being driven by an external motor located in the internal cavity of the terminal body.
[0007] Preferably, both the first and second privacy panels have plugs fixed to their bottoms. Each plug has a semi-circular locking groove at both ends. Each slide has a slot at its top, and each slot has a sliding groove on its sidewall. A slider is slidably connected within each groove. A spring is fixed between the side of the slider and the sidewall of the groove. A locking roller is provided on the surface of the slider. When the privacy panel has been in use for a long time, it requires regular maintenance. However, a fixed connection would prolong maintenance time and increase disassembly steps. To address this issue, this invention uses a detachable connection method. During installation, the plug at the bottom of the privacy panel is inserted into the slot at the top of the slide. The plug presses against the locking rollers on both sides until the semi-circular locking groove engages with the locking roller. Under the spring force, the locking roller engages with the locking groove. Disassembly is simple; the plug is pulled out forcefully. The operation is simple, disassembly and assembly are quick, and maintenance is convenient.
[0008] Preferably, the bottom end of the plug is designed as an arc surface. The arc surface design reduces the contact area between the plug and the engaging roller, making it easier for the plug to be inserted into the slot.
[0009] Preferably, the engaging roller is rotatably connected to the slider, which further facilitates the insertion of the plug into the slot.
[0010] Preferably, the surface of the engaging roller is covered with a rubber sleeve. The rubber sleeve not only reduces the wear of the engaging roller, but also increases the friction between the engaging roller and the semi-circular locking groove, thereby improving the stability of the plug.
[0011] Preferably, the sidewall of the arc-shaped groove is bonded with an anti-pinch sleeve. Because the privacy panel is made of a hard material, it can easily cause pressure on the consumer's wrist, and there may be burrs at the arc-shaped groove, which can easily cause injury to the consumer's wrist, causing unnecessary harm and trouble. To address these issues, this utility model has an anti-pinch sleeve bonded to the arc-shaped groove. The anti-pinch sleeve is made of elastic material, which effectively covers any burrs that may be present. At the same time, it acts as a buffer when the privacy panel clamps the wrist, preventing the hard material from directly contacting the skin, thereby greatly reducing the risk of wrist injury to the consumer and providing a safer, more comfortable and considerate user experience.
[0012] Preferably, the surface of the semi-circular locking groove is provided with anti-slip texture, which further increases the friction between the locking roller and the semi-circular locking groove, thereby improving the stability of the plug.
[0013] Beneficial effects
[0014] Existing privacy shields generally adopt an open front compartment design. While this ensures the user's arm can freely extend and operate with flexibility, it introduces new security risks. However, actual test data shows that in a standard bank counter scenario, an observer within a 135° fan-shaped area to the side and rear can form an effective viewing angle of about 12° through the opening. Especially when users are entering complex passwords, about 23% of the input actions will expose some key information due to finger movement. More concerning is that in recent years, in cases of "shoulder peeping," some people often use miniature wide-angle cameras with telephoto lenses to capture 82% of keystrokes through the privacy shield opening at a distance of 1.5 meters, thereby reading the consumer's password. This poses a low level of security. To address these issues, this utility model adopts an open privacy shield mechanism. When the consumer puts their hand into the privacy shield to enter the password, an external motor drives a lead screw to rotate. The lead screw moves the first and second privacy plates towards each other until the opening is largely covered, preventing others from intentionally peeping through the opening. This improves the consumer's security without hindering the consumer from entering the password. Attached Figure Description

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:
[0027] Reference Figure 1-7The security anti-peeping structure of the bank self-service terminal includes a terminal body 1. A display screen 101 is located at the top of the terminal body 1. The surface of the terminal body 1 is sequentially provided with a card slot, an input keyboard, a printer port, and a reader. An anti-peeping cover 2 is fixed to the surface of the input keyboard. The top of the anti-peeping cover 2 has an array of louvers arranged at an angle. A lead screw 5 is connected to the inner cavity of the terminal body 1 via a bearing. Both ends of the lead screw 5 are threadedly connected to slide blocks 4. An anti-peeping groove is formed on the surface of the terminal body 1. The slide blocks 4 are slidably connected to the anti-peeping groove. A first anti-peeping plate 3 and a second anti-peeping plate 6 are detachably connected to the top of the two slide blocks 4, respectively. Both the first anti-peeping plate 3 and the second anti-peeping plate 6 have arc-shaped grooves on their surfaces. The curved groove 301 has an anti-pinch sleeve bonded to its side wall. Because the privacy panel is made of a relatively hard material, it can easily cause pressure on the consumer's wrist. Furthermore, there may be burrs at the curved groove 301, which could easily cause wrist injuries, leading to unnecessary harm and inconvenience. To address these issues, this invention incorporates an anti-pinch sleeve bonded to the curved groove 301. The anti-pinch sleeve is made of elastic material, effectively covering any potential burrs. Simultaneously, it acts as a buffer when the privacy panel clamps the wrist, preventing direct contact between the hard material and the skin, thus significantly reducing the risk of wrist injury and providing a safer, more comfortable, and considerate user experience. Additionally, the internal thread grooves of the two sliding blocks 4 are in opposite directions, and the lead screw 5 is driven by an external motor located within the inner cavity of the terminal body 1.
[0028] Both the first privacy screen 3 and the second privacy screen 6 have plugs 601 fixed at their bottoms. The bottom end of the plug 601 is designed with an arc surface. The arc surface design reduces the contact area between the plug 601 and the locking roller 7, making it easier for the plug 601 to be inserted into the slot 401. Both ends of the plug 601 are provided with semi-circular locking grooves. The surface of the semi-circular locking grooves is provided with anti-slip textures. The anti-slip textures further increase the friction between the locking roller 7 and the semi-circular locking grooves, improving the stability of the plug 601. Each slide block 4 has a slot 401 on its top, and a groove on the side wall of each slot 401. A slider 8 is slidably connected within the groove. A spring 9 is fixed between the side of the slider 8 and the side wall of the groove. A locking roller 7 is provided on the surface of the slider 8. When the privacy screen has been in use for a long time, it requires regular maintenance. However, a fixed connection would prolong maintenance time and increase disassembly steps. To address this issue, this invention uses a detachable connection. During installation, the bottom plug 601 of the privacy screen is inserted into the slot 401 at the top of the slide block 4. The plug 601 presses against the locking roller 7 on both sides until the semi-circular locking groove engages with the locking roller 7. Under the elastic force of the spring 9, the locking roller 7 engages with the locking groove. Disassembly is simple; the plug 601 is pulled out forcefully. The operation is simple, disassembly and assembly are quick, and maintenance is convenient. The locking roller 7 is rotatably connected to the slider 8, further facilitating the insertion of the plug 601 into the slot 401. The surface of the locking roller 7 is covered with a rubber sleeve. The rubber sleeve not only reduces the wear of the locking roller 7, but also increases the friction between the locking roller 7 and the semi-circular locking groove, thereby improving the stability of the plug 601.
[0029] The working principle of this utility model is as follows: Insert the plug 601 at the bottom of the privacy screen into the slot 401 at the top of the slide block 4. The plug 601 presses the locking roller 7 to both sides until the semi-circular locking groove engages with the locking roller 7. Under the elastic force of the spring 9, the locking roller 7 engages with the locking groove. When the consumer puts his hand into the privacy screen to enter the password, the external motor drives the lead screw 5 to rotate. The lead screw 5 drives the first privacy screen 3 and the second privacy screen 6 to move towards each other until the opening is largely covered. To disassemble, simply pull out the plug 601.
[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
