Description

Technical Field

[0001] This invention relates to the field of ATM technology, and more particularly to an ATM device and a method for preventing ATM devices from being spied on. Background Technology

[0002] Currently, ATMs are equipped with anti-peeping mechanisms that allow a line of sight to pass through at a set angle, thus preventing peeping. However, the anti-peeping angle of existing mechanisms is fixed. Pinhole cameras can bypass the viewing angle by getting close to the hole, adjusting the focus, or choosing a specific angle (such as obliquely approaching the side panel), thus achieving close-range spying. The fixed angle cannot cope with dynamic peeping from different directions (such as the upper side or the oblique front), creating blind spots in protection. Summary of the Invention

[0003] This invention provides an ATM device and an anti-peeping method for ATM devices, applicable to various types of ATM devices, including but not limited to ATMs, automatic deposit machines, deposit and withdrawal machines, and large-amount deposit and withdrawal devices. By driving multiple anti-peeping blades to rotate clockwise or counterclockwise by a set angle along the axial direction of the anti-peeping blades, the anti-peeping angle of the anti-peeping cover is dynamically adjusted to interfere with the fixed field of view of the pinhole camera, blocking multi-directional spying and improving security.

[0036] Figure 3 This is a flowchart illustrating an anti-peeping method for an ATM device provided in an embodiment of the present invention. Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be fully described below with reference to the accompanying drawings in the embodiments of this invention, through specific implementation methods. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort fall within the protection scope of this invention.

[0038] Figure 1 This is a schematic diagram of the structure of an ATM device provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of a grid frame provided in an embodiment of the present invention. See also: Figure 1 and Figure 2The ATM device includes a support base 01. The support base 01 is equipped with an operating table 10, a privacy shield 20, and a drive assembly (not shown). The operating table 10 has a button area. The privacy shield 20 includes a grille frame 210, a privacy side panel 220, and multiple privacy blades 230. The grille frame 210 is positioned on top of the privacy side panel 220, covering the button area. The privacy side panel 220 surrounds the button area and has an opening on the side facing the withdrawal position. The privacy blades 230 provide privacy at certain angles. Multiple privacy blades 230 are laid on the grille frame 210 to allow a line of sight at a set angle to the button area in the initial state, where the multiple privacy blades 230 are horizontal. The drive assembly includes a first drive assembly, which is connected to a plurality of privacy blades 230 for driving the plurality of privacy blades 230 to rotate clockwise or counterclockwise by a set angle along the axial direction of the privacy blades 230, so as to dynamically adjust the privacy angle of the privacy cover 20 according to a preset rule.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, a privacy screen 20 is fitted around the operating table 10, and the privacy screen 20 includes a grid frame 210 and a privacy side panel 220. The privacy side panel 220 surrounds part of the operating table 10 to provide an opening facing the user's withdrawal position, thereby ensuring that the user can input data at the operating table. The grid frame 210 is located on top of the privacy side panel 220. Multiple privacy blades 230 are laid on the grid frame 210. The privacy blades 230 can be made of privacy acrylic sheets (light transmittance 30%-50%). When viewed from the front (at a near-vertical angle, such as within ±30° or ±45°), the view can pass through the privacy blades 230. When viewed from the side (beyond the set angle), the view is blocked by the privacy blades 230. Thus, when multiple privacy blades 230 are laid on the grille frame 220 and the multiple privacy blades 230 are in the initial state, that is, the multiple privacy blades are in the horizontal state, the multiple privacy blades 230 allow the line of sight to pass through at a set angle (such as a near-vertical angle) to the button area. The line of sight beyond the set angle will be blocked by the multiple privacy blades 230, thereby achieving the privacy effect.

[0040] Furthermore, this embodiment of the invention also includes a first driving component, which is connected to multiple privacy shutters 230 via a transmission connection, thereby driving the multiple privacy shutters 230 to rotate synchronously. For example, when it is detected that a user needs to input on the control panel 10, the first driving component drives the multiple privacy shutters 230 to rotate clockwise by 45° along the axial direction of the privacy shutters 230, and then counterclockwise by 90°. During this rotation, the privacy shutter angle of the privacy shutters 230 also changes continuously, thus ensuring that the user can see the button area while the privacy shutter angle dynamically changes, interfering with the fixed field of view of the pinhole camera, blocking multi-directional filming, and improving security.

[0041] It should be noted that the embodiments of the present invention do not limit the preset rules for the rotation of multiple privacy blades 230. Those skilled in the art can set them as needed, as long as it is ensured that the user can see the button area while the privacy angle is dynamically changing.

[0042] It should also be noted that the ATM devices provided in the embodiments of the present invention include, but are not limited to, automated teller machines, automated deposit machines, deposit and withdrawal machines, and large-amount deposit and withdrawal devices. The present invention does not impose any limitations on these, and those skilled in the art can configure them as needed.

[0043] In summary, the supporting base of this invention is provided with an operating table, a privacy shield, and a driving assembly. The operating table has a button area. The privacy shield includes a grille frame, privacy side panels, and multiple privacy blades. The grille frame is located on top of the privacy side panels, covering the button area. The privacy side panels surround the button area and have an opening on the side facing the withdrawal position. The privacy blades provide privacy at certain angles. Multiple privacy blades are laid on the grille frame to allow a line of sight perpendicular to the button area to pass through in the initial state, where the multiple privacy blades are horizontal. The driving assembly includes a first driving assembly, which is kinetically connected to the multiple privacy blades. This first driving assembly drives the multiple privacy blades to rotate clockwise or counterclockwise by a set angle along the axial direction of the privacy blades, dynamically adjusting the privacy angle of the privacy shield according to a preset rule. Thus, when a user withdraws money, the dynamic adjustment of the privacy angle of the privacy shield interferes with the fixed field of view of the pinhole camera, blocking multi-directional filming and improving security.

[0044] It should be noted that the above embodiment is illustrated by the dynamic adjustment of multiple privacy blades 230, but it is not a limitation. In other embodiments, an infrared array sensor can also be set on the privacy cover 20. The infrared array sensor can detect the viewing position of the camera, and adjust the rotation angle of multiple privacy blades in real time according to the viewing position, thereby actively disrupting the fixed framing range of the camera.

[0045] Optionally, based on the above embodiments, the first driving component includes a stepper motor, a driving gear, a driven gear, and a synchronous belt. The output shaft of the stepper motor is connected to the driving gear. The privacy blade 230 is mounted on the grille frame 210 via bearings. The shaft end of the bearing is connected to the driven gear, and the driven gear meshes with the driving gear via the synchronous belt. Specifically, the bearing can control the axial position of the privacy blade 230. The shaft end of the bearing is connected to the output shaft of the stepper motor via the driven gear and the driving gear. Thus, when the output shaft of the stepper motor rotates, it will drive the privacy blade 230 to rotate, achieving the effect of dynamically adjusting the privacy viewing angle. It is understood that the embodiments of the present invention exemplarily control the rotation of the privacy blade 230 by gear meshing, but this is not a limitation. Other methods can be used in other embodiments, and those skilled in the art can set them as needed.

[0046] It should be noted that a magnetic encoder can also be added to the output shaft of the stepper motor. The magnetic encoder can provide feedback on the real-time rotation angle of the anti-peeping blade 230, thereby achieving precise control.

[0047] It is understood that, in one embodiment, the grille frame 210 covers the operating table 10 and extends beyond the edge area of ​​the operating bar 10 by a set range (e.g., 10cm), thereby reserving installation positions for the first drive assembly on both sides of the grille frame 210.

[0048] Optionally, based on the above embodiments, see also... Figure 1 The support base 01 is also provided with a mounting groove 30. The operating table 10 is fixedly disposed in the mounting groove 30, and the mounting groove 30 forms a mounting cavity 310 around the area of ​​the operating table 10. The privacy screen 20 is vertically and flexibly disposed in the mounting cavity 310. The drive assembly includes a second drive assembly, which is kinetically connected to the privacy screen 20 to drive the privacy screen 20 to rise or fall.

[0049] Specifically, in this embodiment of the invention, the privacy shield 20 can also be vertically mounted within the mounting cavity 310. When it is detected that a user needs to use the operating table 10, the second drive component can drive the privacy shield 20 to rise to a preset height to allow the user to operate. When the user's operation is detected to be complete, the second drive component can drive the privacy shield 20 to descend into the mounting cavity 310. For example, when the second drive component receives a user operation signal (such as the user inserting a card or starting a password input interface), it drives the privacy shield 20 to rise to a preset height, where the preset height can be a suitable height for a medium-sized person (e.g., 15cm above the support base 01). When it is detected that the user has completed a withdrawal, the privacy shield 20 is driven to descend into the mounting cavity 310, thereby protecting the operating table 10 and reducing the chance of a pinhole camera being installed.

[0050] Understandably, the second drive assembly can employ a DC geared motor with a lead screw slide or an electric actuator (thrust 50-100N, stroke 50-150mm, suitable for most adult height adjustment ranges). This type of device provides stable linear motion and allows for precise displacement control via pulse signals (accuracy ±0.5mm), meeting height adjustment requirements. Furthermore, the privacy screen 20 and the second drive assembly can be connected via a bearing slider, using a guide rail (such as a linear slide rail) to limit lateral swaying and ensure smooth lifting (preventing the privacy screen from shaking and affecting operation when the user enters a password).

[0051] Optionally, based on the above embodiments, see also... Figure 1 The support base 01 is also equipped with an upward adjustment button and a downward adjustment button. Both the upward adjustment button and the downward adjustment button are electrically connected to the second drive component. The upward adjustment button is used to control the second drive component to drive the privacy screen 20 to rise at a preset speed, and the downward adjustment button is used to control the second drive component to drive the privacy screen 20 to descend at a preset speed.

[0052] Specifically, based on the aforementioned automatic adjustment, the privacy shield 20 will stop at a preset height when in use. However, the preset height cannot meet the needs of all users. For example, if a user is tall, their line of sight will be higher than the applicable angle of the privacy shield 20, rendering the protection ineffective. Therefore, in addition to the automatic adjustment, this embodiment of the invention also provides manual adjustment buttons, namely an upward adjustment button and a downward adjustment button. Users can use the upward adjustment button to control the second drive component to drive the privacy shield 20 to rise at a preset speed, or use the downward adjustment button to control the second drive component to drive the privacy shield 20 to descend at a preset speed, thereby meeting the privacy needs of users of different heights.

[0053] It is understandable that when users adjust the height of the privacy screen 20 using the up and down adjustment buttons, there are certain limitations: the maximum height that can be raised will not exceed the adjustable height of the privacy screen 20, and the minimum height that can be lowered will not exceed the preset height.

[0054] Optionally, based on the above embodiments, see also... Figure 1 The privacy shield 20 is also equipped with a height sensor to detect its height. The support base 01 is also equipped with a proximity sensor to detect if a user is approaching. The ATM device also includes a control component, which is electrically connected to the first drive component, the height sensor, the second drive component, and the proximity sensor. When the control component determines that a user needs to withdraw cash and the proximity sensor detects the user's approach, it controls the second drive component to raise the privacy shield 20 to a preset height. When the privacy shield 20 reaches the preset height, it controls the first drive component to rotate multiple privacy blades 230 according to a preset rule.

[0055] Specifically, when a user is detected needing to withdraw cash (e.g., when the user inserts a card or enters a PIN and the interface is activated), and the proximity sensor (infrared proximity sensor) detects the user's approach, the control component controls the second drive component to raise the privacy screen 20. When the height sensor (Hall sensor) detects that the privacy screen 20 has risen to a preset height, the control component controls the first drive component to drive multiple privacy blades 230 to rotate according to a preset rule. This ensures that the user can still see the keypad area while the privacy angle dynamically changes, interfering with the fixed field of view of pinhole cameras, blocking multi-directional filming, and improving security. Furthermore, the drive component is also used to control the first drive component to rotate multiple privacy blades 230 to their initial state when the proximity sensor detects that a user has left, and to control the second drive component to lower the privacy screen 20 into the mounting cavity 310, thus restoring the ATM device to its initial state. When the privacy screen 20 lowers into the mounting cavity 310, the grille frame 210 of the privacy screen 20 approaches the operating table 10.

[0056] Optionally, based on the above implementation, a position sensor (such as a through-beam infrared tube) and an alarm component are also provided at the bottom of the mounting cavity 310. The position sensor is used to detect whether the privacy cover 20 has descended to a preset position. The control component is also electrically connected to the position sensor and the alarm component respectively, and is used to control the alarm component to sound an alarm when it is detected that the privacy cover 20 has not descended to the preset position. The preset position can be the lowest height at which the privacy cover 20 descends. For example, the position sensor may include a transmitter and a receiver. The transmitter is installed at the lowest position of the privacy cover 20 (at the same level as the table), and the receiver is installed at the bottom of the privacy cover 20. When it is fully descended, the privacy cover 20 blocks the light path, and the receiver has no signal (determined as "in position"), indicating that the ATM device is operating normally; if it is not fully descended (due to foreign object obstruction), the light path is not blocked, and the receiver continues to receive signals (determined as "abnormal"), indicating that there is a foreign object (such as a pinhole camera) on the privacy cover 20, and the alarm component will sound an alarm. By utilizing the lifting and lowering motion of the privacy shield 20 to synchronously trigger internal foreign object recognition, the system can detect in real time whether a pinhole camera has been installed inside the privacy shield 20, breaking through the limitations of traditional privacy shields and improving the security of cash withdrawals.

[0057] It should be noted that, based on the anomaly detection, this embodiment of the invention also incorporates motor current feedback. When the privacy screen 20 sinks and encounters a foreign object, the motor load increases, and the current exceeds a preset threshold (such as 1.5 times the normal operating current). Combined with the "abnormal" signal from the position sensor, the presence of a foreign object is determined twice (avoiding false judgments from a single sensor, such as dust obstruction).

[0058] Optionally, based on the above embodiment, the support base 01 is further provided with a counterclockwise adjustment button, a clockwise adjustment button, and a reset button. The counterclockwise adjustment button, clockwise adjustment button, and reset button are all electrically connected to the first drive assembly. The counterclockwise adjustment button controls the first drive assembly to drive the multiple privacy blades 230 to rotate counterclockwise at a preset speed. The clockwise adjustment button controls the first drive assembly to drive the multiple privacy blades 230 to rotate clockwise at a preset speed. The reset button controls the first drive assembly to drive the multiple privacy blades 230 to rotate back to their initial state. Thus, based on the above-mentioned automatic control of the dynamic rotation of the multiple privacy blades 230, this embodiment of the invention also provides a manual adjustment button, allowing the user to adjust the rotation angle of the privacy blades 230 according to a preset speed using the counterclockwise adjustment button, clockwise adjustment button, and reset button (each press rotates 10°, with a maximum rotation angle of ±45°, avoiding excessive obstruction of the user's view).

[0059] It should be noted that the control component is also equipped with a current detection module. When the privacy shutter 230 is stuck by a foreign object (such as a user's finger accidentally entering), and the current exceeds 1.2 times the rated value, it will immediately stop rotating and rotate in the opposite direction. At the same time, a slight alarm sound will be emitted through the alarm component (which will not affect the transaction process).

[0060] Optionally, based on the above embodiments, an infrared light array is also provided on the inner side of the privacy shield 20. The infrared light array is used to emit infrared interference light to interfere with the camera's shooting.

[0061] Based on the same inventive concept, embodiments of the present invention also provide a method for preventing eavesdropping on ATM devices. Figure 3 This is a flowchart illustrating an anti-peeping method for an ATM device provided in an embodiment of the present invention. See also... Figures 1-3 The privacy protection method includes:

[0062] S110. Determine if a user is approaching the control panel.

[0063] Specifically, such as Figure 1 and Figure 2As shown, a privacy screen 20 is fitted around the operating table 10, and the privacy screen 20 includes a grid frame 210 and a privacy side panel 220. The privacy side panel 220 surrounds part of the operating table 10 to provide an opening facing the user's withdrawal position, thereby ensuring that the user can input data at the operating table. The grid frame 210 is located on top of the privacy side panel 220. Multiple privacy blades 230 are laid on the grid frame 210. The privacy blades 230 can be made of privacy acrylic sheets (light transmittance 30%-50%). When viewed from the front (at a near-vertical angle, such as within ±30° or ±45°), the view can pass through the privacy blades 230. When viewed from the side (beyond the set angle), the view is blocked by the privacy blades 230. Thus, when multiple privacy blades 230 are laid on the grille frame 220 and the multiple privacy blades 230 are in the initial state, that is, the multiple privacy blades are in the horizontal state, the multiple privacy blades 230 allow the line of sight to pass through at a set angle (such as a near-vertical angle) to the button area. The line of sight beyond the set angle will be blocked by the multiple privacy blades 230, thereby achieving the privacy effect.

[0064] In addition, when a user operation signal is received (such as the user inserting a card, entering a password, or the interface starting up), or when a sensor detects that the user is approaching, it is determined that the user needs to use the control panel 10.

[0065] S120. When the user approaches the operating table, drive multiple privacy blades to rotate clockwise or counterclockwise by a set angle along the axial direction of the privacy blades, so as to dynamically adjust the privacy angle of the privacy cover according to preset rules.

[0066] When the system detects that the user needs to input on the control panel 10, the first drive component drives multiple privacy blades 230 to rotate clockwise by 45° and then counterclockwise by 90° along the axial direction of the privacy blades 230. During this rotation, the privacy angle of the privacy blades 230 is constantly changing, so that while the user can see the button area, the privacy angle is dynamically changing, interfering with the fixed field of view of the pinhole camera, blocking multi-directional spying, and improving security.

[0067] It should be noted that the embodiments of the present invention do not limit the preset rules for the rotation of multiple privacy blades 230. Those skilled in the art can set them as needed, as long as it is ensured that the user can see the button area while the privacy angle is dynamically changing.

[0068] It is understood that the above embodiments are described using the dynamic adjustment of multiple privacy blades 230 as an example, but are not limited thereto. In other embodiments, an infrared array sensor can also be set on the privacy cover 20. The infrared array sensor can detect the viewing position of the camera, and adjust the rotation angle of multiple privacy blades in real time according to the viewing position, thereby actively disrupting the fixed framing range of the camera.

[0069] In summary, this embodiment of the invention determines whether a user is approaching the control panel, and when the user approaches, drives multiple privacy shutters to rotate clockwise or counterclockwise by a set angle along the axial direction of the privacy shutters, dynamically adjusting the privacy shutter angle according to preset rules. Thus, when a user withdraws money, the dynamic adjustment of the privacy shutter angle interferes with the fixed field of view of the pinhole camera, blocking multi-directional filming and improving security.

[0070] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
