Description

Technical Field

[0001] This invention belongs to the field of electronic transaction technology, specifically relating to an Internet of Things (IoT) business transaction device. Background Technology

[0002] IoT business transactions are the product of the deep integration of IoT technology and the business transaction system. Relying on the mature implementation of technologies in multiple fields such as sensing, communication, computing, and encryption, it breaks through the limitations of traditional business transactions, such as "physical separation offline, isolated online data, and lack of connection and intelligence of devices", and realizes the intelligentization, digitalization and collaboration of the entire transaction process.

[0003] Patent CN208013901U discloses an Internet of Things (IoT) business transaction device, which includes a main body with a touch screen, a groove, and multiple buttons on its upper surface; a shield located on one side of the touch screen, the shield including a shield plate and a pair of side wings, the shield plate being pivotally connected to the main body on the side near the touch screen, the shield plate being located above the buttons, the shield plate having a first Velcro fastener on the side facing the buttons, the side wings being pivotally connected to opposite ends of the shield plate, the pivot point of the side wings and the shield plate being located directly above the groove; and a cleaning cloth located below the shield plate, the cleaning cloth having a second Velcro fastener on the side facing the shield plate, the first Velcro fastener and the second Velcro fastener being mutually attached. The aforementioned shield can be folded, reducing the space occupied by the entire device and making it convenient for users to store. However, when the device is not in operation, dust can fall into it, causing the internal electrical structure to malfunction and affecting the normal operation of the device. During transactions, it is difficult to address security risks such as being spied on, followed, or robbed in public settings. Furthermore, it is difficult to protect residual sensitive information after the device is no longer in use. Therefore, an Internet of Things (IoT) business transaction device is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an Internet of Things (IoT) business transaction device to solve the problems of dust falling into the device during shutdown, causing the internal electrical structure to malfunction and affecting the normal operation of the device, and making it difficult to deal with problems such as being spied on, followed, or robbed during transactions in public settings.

[0005] To achieve the above objectives, the present invention provides an Internet of Things (IoT) business transaction device, comprising: a base, a protective mechanism provided on the top surface of the base, an identification mechanism provided inside the protective mechanism, and an anti-peeping mechanism provided above the base; The protective mechanism includes a workbench, which is fixedly connected to the top surface of the machine base. A protective cover is rotatably connected to the top surface of the workbench. A guide plate is fixedly connected to the bottom of the protective cover. A groove plate is fixedly connected to the bottom of the workbench. The surface of the guide plate is in contact with the inner wall of the groove plate.

[0006] In one or more embodiments of the present invention, a guide post is fixedly connected inside the slot plate, and a driven block is slidably connected to the circumferential surface of the guide post by a spring. The edge of the driven block is in contact with the inner wall of the slot plate, and a sliding column is fixedly connected to the side of the driven block. The sliding column is set on the movement trajectory of the guide plate. When the device is running, the operator pulls the protective cover to rotate until it contacts the top surface of the workbench. The operator then pulls the protective cover to cover the operating plate, thus protecting the transaction during operation. The flexibility of the rotatable protective cover can maximize its fit to the dynamic use state of the device during operation without affecting the operator's operation, and preventing information leakage during transactions.

[0007] In one or more embodiments of the present invention, the protective mechanism further includes a rack, which is fixedly connected to the top of the driven block. A rotating plate is rotatably connected to the inner wall of the workbench, and a gear is fixedly connected to the side of the rotating plate. The rack and the gear mesh with each other. When the device stops running, the worker pulls the protective cover to rotate. The protective cover drives the guide plate to rotate. The rotation of the guide plate drives the sliding column to move forward along the inner wall of the guide plate. The movement of the sliding column drives the driven block to move forward. The movement of the driven block drives the rack to move. The movement of the rack drives the gear meshing with it to rotate. The rotation of the gear drives the rotating plate to rotate. The rotation of the rotating plate drives the operating plate to rotate. The rotation of the protective cover drives the operation plate to rotate, thus protecting the operation plate when the device is stopped. This prevents dust from falling into the operation plate after the device has been stopped for a long time, causing the operation plate to malfunction and affecting the normal operation of the device during the next use.

[0008] In one or more embodiments of the present invention, the identification mechanism includes an identification probe, which is fixedly connected to the top surface of the base. An external interface is fixedly connected to the bottom of the worktable. An active plate is slidably connected to the inner wall of the slot plate. A plug is fixedly connected to the top of the active plate. The active plate is set on the movement trajectory of the plug. While the driven block moves forward, the driven block drives the guide column to move forward. The guide column drives the active plate to move forward. The forward movement of the active plate drives the plug to move forward. The movement of the plug drives the fixing pin to move forward. When the fixing pin moves to the working range of the electric push rod, the plug drives the fixing pin to rotate along the circumferential surface of the fixing column. The forward movement of the driven block drives the fixing pin to rotate, thus realizing the fixation of the power cord during device operation. During device operation, if the plug becomes loose, it will directly cause the device to lose power and the transaction to be interrupted, which will not only cause order loss, but also cause the transaction data to be out of sync and the cloud monitoring to be disconnected. The rotating fixing pin solves the problem of device power failure and shutdown caused by loose or detached plugs in commercial scenarios.

[0009] In one or more embodiments of the present invention, the identification mechanism further includes an electric push rod, which is fixedly connected to the inner wall of the workbench. An active block is fixedly connected to the telescopic end of the electric push rod, and a fixed post is fixedly connected to the top surface of the active block. A fixing pin is hinged to the surface of the plug via a torsion spring. The fixing post is positioned on the movement trajectory of the fixing pin. When an operator is conducting a transaction, the identification probe identifies the operator. If an unrecorded person appears behind the operator during the transaction, the identification probe sends a signal to the electric push rod. Upon receiving the signal, the electric push rod retracts its telescopic end, causing the active block to move to the right. The active block then moves backward, causing the fixing post to move to the right. The fixing post then rotates the fixing pin. When the fixed column moves out of the working range of the fixed pin, the fixed pin rotates and resets due to the action of the torsion spring connecting the fixed pin and the plug. At this time, the active plate moves backward due to the tension of the spring connecting the guide column and the slot plate. The plug moves backward until it leaves the working range of the external interface. The electric push rod moves to the right, driving the plug to disconnect the power to the device. This active safety solution, which links the identification probe with the fixed pin, focuses on the protection of personal and property safety in transaction scenarios. It addresses the safety hazards of being spied on, followed, or robbed during transactions in public scenarios by "actively detecting and immediately disconnecting the power" to cut off the transaction process and terminate sensitive operations. At the same time, the mechanical fixing characteristics of the rotating pin ensure the safe disconnection of the electrical connection, thus guaranteeing the security of the transaction.

[0010] In one or more embodiments of the present invention, the privacy protection mechanism includes a driven column, which is fixedly connected to the surface of the active block, and a baffle is slidably connected to the inner wall of the base, with a guide groove formed on the surface of the baffle.

[0011] In one or more embodiments of the present invention, the driven column is slidably connected to the inner wall of the guide groove opened on the surface of the baffle, the display screen is fixedly connected to the surface of the base, the fixing strip is fixedly connected to the surface of the base, and the limit plate is fixedly connected to the side of the worktable. When the active block moves to the right, the active block drives the driven column to move to the right, and the driven column drives the baffle to move upward along the guide groove opened on the surface of the baffle on the inner wall of the base until it completely blocks the display screen. The movement of the active block to the right drives the driven column to move upward, realizing the blocking of the display screen by the driven column. This is a mechanical protection upgrade and safety supplement to the intelligent detection and power failure protection scheme. It not only solves the vulnerability that the display screen may still retain sensitive information after a simple power failure, but also makes the protection action more synchronous and thorough through mechanical linkage. At the same time, it takes into account the user experience of the display screen when the device is running normally, thus improving the safety of the device.

[0012] In one or more embodiments of the present invention, a fixing block is fixedly connected to the surface of the limiting plate, a spiral rod is rotatably connected to the inner wall of the fixing block, and the fixing strip is rotatably connected to the spiral rod.

[0013] In one or more embodiments of the present invention, a movable block is helically connected to the circumferential surface of the helical rod, and a friction wheel is fixedly connected to the end of the helical rod away from the fixed block, and the friction wheel is rotatably connected to the inner wall of the fixed strip.

[0014] In one or more embodiments of the present invention, the anti-peeping mechanism further includes a rocker arm rotatably connected to the top surface of the movable block, and an anti-peeping plate rotatably connected to the side of the base. The end of the rocker arm away from the movable block is rotatably connected to the anti-peeping plate. During the process of the baffle rising, when the baffle moves to the working range of the friction wheel, the baffle drives the friction wheel to rotate. The rotation of the friction wheel drives the spiral rod to rotate. The rotation of the spiral rod drives the movable block to move forward on the cylindrical surface of the spiral rod. At the same time, the movement of the movable block drives the rocker arm to rotate on the surface of the anti-peeping plate. The rotation of the rocker arm pulls the anti-peeping plate to rotate. The rise of the baffle drives the anti-peeping plate to rotate, thus achieving the shielding of the device. This is the final supplement to the physical protection system of the device. It not only blocks all physical channels for the leakage of sensitive information and malicious operation, but also retains the simplicity of the device structure and the synchronicity of the action. At the same time, it adapts to the full-dimensional security protection needs of public transaction scenarios.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the coordinated operation of the workbench, protective cover, guide plate, sliding column, driven block, guide column, slotted plate, rack, rotating plate, gear, and operating plate, the worker pulls the protective cover to cover the operating plate, thus protecting the transaction during operation. The flexibility of the rotating protective cover maximizes its fit to the dynamic use state of the device during operation without affecting the worker's operation, preventing information leakage during transactions. The rotation of the protective cover drives the rotation of the operating plate, thus protecting the operating plate when the device ends, preventing dust from falling into the operating plate during long-term shutdown, which could cause the operating plate to malfunction and affect the normal operation of the device in the next use.

[0016] 2. By coordinating the operation of the identification probe, external interface, active block, active board, plug, fixed post, fixed pin, and electric push rod, the driven block moves forward, driving the fixed pin to rotate. This secures the power cord during device operation. If the plug becomes loose during operation, it directly causes a power outage and transaction interruption, resulting in order losses, data synchronization issues, and loss of cloud monitoring connectivity. The rotating fixed pin solves the problem of power outages caused by loose or detached plugs in commercial scenarios. The electric push rod moves to the right, driving the plug to disconnect the device from power. This proactive safety solution, linking the identification probe and the fixed pin, focuses on protecting personal and property safety in transaction scenarios. Addressing security risks such as eavesdropping, tailing, and robbery during transactions in public settings, it interrupts the transaction process and terminates sensitive operations through "proactive detection and immediate power disconnection." Simultaneously, the mechanical fixing characteristics of the rotating pin ensure a safe disconnection of the electrical connection, guaranteeing transaction security.

[0017] 3. Through the coordinated operation of the driven column, baffle, display screen, fixing strip, fixing block, spiral rod, movable block, friction wheel, rocker arm, limit plate, and privacy screen, the driven column moves upward as the active block moves to the right, thus blocking the display screen. This is a mechanical protection upgrade and security supplement to the intelligent detection and power failure protection scheme. It not only solves the vulnerability that sensitive information may remain on the display screen after a simple power failure, but also makes the protection action more synchronized and thorough through mechanical linkage. At the same time, it takes into account the user experience of the display screen during normal operation of the device, thereby improving the security of the device. The baffle rises and drives the privacy screen to rotate, thus blocking the device. This is the final supplement to the physical protection system of the device. It not only blocks all physical channels for the leakage of sensitive information and malicious operation, but also retains the simplicity of the device structure and the synchronicity of the action. At the same time, it adapts to the full-dimensional security protection needs of public transaction scenarios. Attached Figure Description

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figure 1-8 As shown, one embodiment of the present invention is: an Internet of Things business transaction device, including: a base 1, a protective mechanism 2 is provided on the top surface of the base 1, an identification mechanism 3 is provided inside the protective mechanism 2, and an anti-peeping mechanism 4 is provided above the base 1; The protective mechanism 2 includes a workbench 21, which is fixedly connected to the top surface of the base 1. A protective cover 22 is rotatably connected to the top surface of the workbench 21. A guide plate 23 is fixedly connected to the bottom of the protective cover 22. A slotted plate 27 is fixedly connected to the bottom of the workbench 21. The surface of the guide plate 23 is in contact with the inner wall of the slotted plate 27. When the worker pulls the protective cover 22, it can cover the operating plate 211, thus protecting the transaction during the operation of the device. The flexibility of the rotatable protective cover 22 can maximize the fit with the dynamic use state of the device during operation, while not affecting the worker's operation, thus preventing information leakage during the transaction.

[0022] A guide post 26 is fixedly connected inside the slot plate 27. A driven block 25 is slidably connected to the circumferential surface of the guide post 26 by a spring. The edge of the driven block 25 is in contact with the inner wall of the slot plate 27. A sliding post 24 is fixedly connected to the side of the driven block 25. The sliding post 24 is set on the movement trajectory of the guide plate 23.

[0023] The protective mechanism 2 also includes a rack 28, which is fixedly connected to the top of the driven block 25. A rotating plate 29 is rotatably connected to the inner wall of the worktable 21, and a gear 210 is fixedly connected to the side of the rotating plate 29. The rack 28 and the gear 210 mesh with each other. The rotation of the protective cover 22 drives the operation plate 211 to rotate, thus protecting the operation plate 211 when the device is stopped. This prevents dust from falling into the operation plate 211 after the device has been stopped for a long time, which could cause the operation plate 211 to malfunction and affect the normal operation of the device during the next use.

[0024] The identification mechanism 3 includes an identification probe 31, which is fixedly connected to the top surface of the base 1. An external interface 32 is fixedly connected to the bottom of the workbench 21. An active plate 34 is slidably connected to the inner wall of the slot plate 27. A plug 35 is fixedly connected to the top of the active plate 34. The active plate 34 is set on the movement trajectory of the plug 35. The driven block 25 moves forward and drives the fixing pin 37 to rotate, which realizes the fixation of the power cord when the device is running. If the plug 35 is loose during device operation, it will directly cause the device to lose power and the transaction to be interrupted. This will not only cause order loss, but also cause the transaction data to be out of sync and the cloud monitoring to be disconnected. The fixed pin 37 solves the problem of device power loss and shutdown caused by the loosening and falling off of the plug 35 in commercial scenarios.

[0025] The identification mechanism 3 also includes an electric push rod 38, which is fixedly connected to the inner wall of the workbench 21. The telescopic end of the electric push rod 38 is fixedly connected to an active block 33, and the top surface of the active block 33 is fixedly connected to a fixed post 36. The surface of the plug 35 is hinged to a fixed pin 37 by a torsion spring. The fixed post 36 is set on the movement trajectory of the fixed pin 37. The electric push rod 38 moves to the right, driving the plug 35 to cut off the power to the device. This active safety solution links the identification probe 31 with the fixed pin 37. The core of this solution is to protect the personal and property safety of people in the transaction scenario. It addresses the safety hazards such as being spied on, followed, or robbed during transactions in public scenarios. It cuts off the transaction process and terminates sensitive operations by "active detection and immediate power-off". At the same time, it combines the mechanical fixing characteristics of the rotating pin to achieve a safe disconnection of the electrical connection, ensuring the security of the transaction.

[0026] Working principle: When the device is running, the operator pulls the protective cover 22 to rotate until it contacts the top surface of the workbench 21. The operator then pulls the protective cover 22 to cover the operating panel 211, thus protecting the transaction during operation. The flexibility of the rotating protective cover 22 maximizes its adaptability to the dynamic usage state of the device during operation without affecting the operator's operation, preventing information leakage during transactions. When the device stops running, the operator pulls the protective cover 22 to rotate, which in turn rotates the guide plate 23. The rotation of the guide plate 23 causes the sliding column 24 to move along the guide... The inner wall of plate 23 moves forward, the sliding column 24 moves, driving the driven block 25 to move forward, the driven block 25 moves, driving the rack 28 to move, the rack 28 moves, driving the gear 210 meshing with it to rotate, the gear 210 rotates, driving the rotating plate 29 to rotate, the rotating plate 29 rotates, driving the operating plate 211 to rotate, and the rotating protective cover 22 rotates, driving the operating plate 211 to rotate, thus protecting the operating plate 211 when the device is stopped, preventing dust from falling into the operating plate 211 after the device has been stopped for a long time, causing the operating plate 211 to malfunction, thereby affecting the normal operation of the device when it is used again.

[0027] As the driven block 25 moves forward, it drives the guide column 26 forward, which in turn drives the active plate 34 forward. The active plate 34 then drives the plug 35 forward, which in turn drives the fixing pin 37 forward. When the fixing pin 37 moves to the working range of the electric push rod 38, the plug 35 drives the fixing pin 37 to rotate along the circumference of the fixing column 36. The forward movement of the driven block 25 drives the fixing pin 37 to rotate, thus securing the power cord during device operation. If the plug 35 becomes loose during device operation, it will directly cause a power outage and transaction interruption, resulting in order losses, unsynchronized transaction data, and loss of connection to cloud monitoring. The rotating fixing pin 37 solves the problem of power outages and shutdowns caused by loose or detached plugs in commercial scenarios. When an operator is conducting a transaction, the identification probe 31 identifies the operator. If an unrecorded person appears behind the operator during the transaction, the identification probe 31 sends a signal to the electric push rod 38, which receives the signal. After the telescopic end retracts, the telescopic end of the electric push rod 38 drives the active block 33 to move to the right. The active block 33 moves backward, driving the fixed column 36 to move to the right. The fixed column 36 drives the fixed pin 37 to rotate. When the fixed column 36 moves away from the working range of the fixed pin 37, the fixed pin 37 rotates and resets due to the action of the torsion spring connecting the fixed pin 37 and the plug 35. At this time, the active plate 34 moves backward due to the tension of the spring connecting the guide column 26 and the slot plate 27. The plug 35 moves backward until it leaves the working range of the outer interface 32. The electric push rod 38 moves to the right, driving the plug 35, thus realizing the power cut-off of the device. The active safety scheme that links the identification probe 31 and the fixed pin 37 revolves around the protection of personal and property safety in the transaction scenario. In response to the safety hazards such as being spied on, followed, and robbed during transactions in public scenarios, the transaction process is cut off and sensitive operations are terminated by "active detection and immediate power cut-off". At the same time, the mechanical fixing characteristics of the rotating pin are combined to realize the safe disconnection of the electrical connection, ensuring the security of the transaction.

[0028] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the anti-peeping mechanism 4 includes a driven column 41, which is fixedly connected to the surface of the active block 33. A baffle 42 is slidably connected to the inner wall of the base 1, and a guide groove is provided on the surface of the baffle 42.

[0029] The driven column 41 is slidably connected to the inner wall of the guide groove opened on the surface of the baffle 42. The display screen 43 is fixedly connected to the surface of the base 1, and the fixing strip 44 is fixedly connected to the surface of the base 1. The side of the worktable 21 is fixedly connected to the limit plate 410. The driven column 41 moves upward by the movement of the active block 33 to the right, realizing the shielding of the display screen 43 by the driven column 41. This is a mechanical protection upgrade and safety supplement to the intelligent detection and power failure protection scheme. It not only solves the loophole that the display screen 43 may still retain sensitive information after a simple power failure, but also makes the protection action more synchronous and thorough through mechanical linkage. At the same time, it takes into account the user experience of the display screen 43 when the device is running normally, thus improving the safety of the device.

[0030] A fixing block 45 is fixedly connected to the surface of the limiting plate 410, and a spiral rod 46 is rotatably connected to the inner wall of the fixing block 45. The fixing strip 44 is rotatably connected to the spiral rod 46.

[0031] A movable block 47 is helically connected to the circumferential surface of the spiral rod 46. A friction wheel 48 is fixedly connected to the end of the spiral rod 46 away from the fixed block 45. The friction wheel 48 is rotatably connected to the inner wall of the fixed strip 44.

[0032] The anti-peeping mechanism 4 also includes a rocker arm 49, which is rotatably connected to the top surface of the movable block 47. An anti-peeping plate 411 is rotatably connected to the side of the base 1. The end of the rocker arm 49 away from the movable block 47 is rotatably connected to the anti-peeping plate 411. The anti-peeping plate 411 rotates as the baffle 42 rises, thus achieving the shielding of the device. This is the final supplement to the physical protection system of the device, which not only blocks all physical channels for the leakage of sensitive information and malicious operation, but also retains the simplicity of the device structure and the synchronicity of the action. At the same time, it adapts to the full-dimensional security protection needs of public transaction scenarios.

[0033] Working principle: As the active block 33 moves to the right, it drives the driven column 41 to move to the right. The driven column 41 then drives the baffle 42 to move upward along the guide groove on the surface of the baffle 42 on the inner wall of the base 1 until it completely blocks the display screen 43. The movement of the active block 33 to the right drives the driven column 41 to move upward, thus achieving the blocking of the display screen 43 by the driven column 41. This is a mechanical protection upgrade and safety supplement to the intelligent detection and power failure protection scheme. It not only solves the vulnerability that the display screen 43 may still retain sensitive information after a simple power failure, but also makes the protection action more synchronized and thorough through mechanical linkage. At the same time, it takes into account the user experience of the display screen 43 during normal operation of the device, improving the safety of the device. As the baffle 42 rises... During the process, when the baffle 42 moves to the working range of the friction wheel 48, the baffle 42 drives the friction wheel 48 to rotate. The rotation of the friction wheel 48 drives the spiral rod 46 to rotate. The rotation of the spiral rod 46 drives the movable block 47 to move forward on the cylindrical surface of the spiral rod 46. At the same time, the movement of the movable block 47 drives the rocker arm 49 to rotate on the surface of the privacy plate 411. The rotation of the rocker arm 49 pulls the privacy plate 411 to rotate. The baffle 42 rises and drives the privacy plate 411 to rotate, thus achieving the shielding of the device. This is the final supplement to the physical protection system of the device. It not only blocks all physical channels for the leakage of sensitive information and malicious operation, but also retains the simplicity of the device structure and the synchronicity of the action. At the same time, it adapts to the full-dimensional security protection needs of public transaction scenarios.
