August 28, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventors Liu, Dongbo (Guangzhou, CN); Huang, Shaohai (Guangzhou, CN), filed on July 9, 2012, was made available online on August 14, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to GRG Banking Equipment Co., Ltd.

The following quote was obtained by the news editors from the background information supplied by the inventors: "The financial self-service device has been widely used in everyday life, and can provide 24-hour continuous service and bring significant convenience for customers. However, for the unattended automated teller machine, there exists a risk that the money of is the depositor may be stolen or intercepted by criminals. Therefore, the application security of the financial self-service device is causing more and more attention. For providing a violence-preventing protection for the financial self-service device, there are several structural embodiments which can realize the function of a shutter of the financial self-service device, such as opening, closing and locking function.

"The shutter structure of some commercially available financial self-service devices mainly has two action principles, that is, a sliding manner, in which the shutter is placed horizontally or tilted at a certain degree, and a pivoting manner. One solution uses a principle of the shutter mechanism sliding back and forth in a certain plane. For example, as disclosed in a patent application No. 200910041871.7 titled 'A safe shutter device and an automated teller machine having the same' with the publication No. CN101684713A, two planar sliding grooves are respectively provided at two sides of the shutter of the safe shutter device, the shutter mechanism is driven by a force to slide back and forth along a fixed sliding groove, and two extreme positions of the planar sliding groove respectively correspond to an open state and a close state of the shutter mechanism. The major problem of such shutter mechanism is that, because the mounting space is relatively large due to the alternative open and close states, the shutter mechanism is generally adapted to be placed horizontally or tilted.

"In another solution, the shutter mechanism rotates around an axis to realize the open and close actions. For example, in the automatic shutter device disclosed in the patent application No. 200910193709.7 with the publication No. CN101840596A, one end of the shutter of the device is fixed on a rotating axis, and the shutter is driven by a force to rotate around the axis by a certain angle from an initial angle, such that the shutter is in close and open states respectively. The major problem of such shutter mechanism is that, the enveloping space of the spatial motion is relatively large due to the motion manner, thus enough space is required for realizing the action of the shutter, and if there is a requirement on the space limitation, the application of such shutter mechanism is not convenient. A shutter mechanism on the product LOBBY90 of Wincor Company, which also rotates around an axis, solves the problem of the large motion enveloping space, however the arc shutter plate causes a lot of inconveniences during the overall mounting and fitting process.

"Further, for some through-the-all or outdoor placed financial self-service devices, the transaction interface is generally exposed, which requires the shutter having a certain rainproof function.

"Therefore, it is urgent to provide a shutter mechanism which is able to reduce the enveloping space of the motion of the shutter and has a compact structure."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "The object of the present application is to provide a shutter mechanism which is able to reduce the enveloping space of the motion of the shutter and has a compact structure,

"For realizing the above object, the present application provides a shutter mechanism mounted on a lateral frame of a banknote port of a financial self-service device. The shutter mechanism includes a shutter, a driving mechanism, and a locking mechanism for controlling the shutter. A lower end of the shutter is slidably connected to a front end of a lateral surface of the frame in an up-down direction, an upper end of the shutter is slidably connected to an upper end of the lateral surface of the frame in a front-back direction, and the upper end of the shutter is driven by the driving mechanism to slide along the upper end of the lateral surface of the frame front and back, which meanwhile drives the lower end of the shutter to move along the front end of the lateral surface of the frame up and down, thereby realizing the opening and closing of the shutter.

"Preferably, a first sliding groove is provided at the front end of the lateral surface of the frame in an up-down direction, a second sliding groove is provided at the upper end of the lateral surface of the frame in a front-back direction, a first sliding portion extending from the lower end of the shutter cooperates with the first sliding groove, and a second sliding portion extending from the upper end of the shutter cooperates with the second sliding groove. Due to the cooperating between the first sliding groove and the first sliding portion and the cooperating between the second sliding groove and the second sliding portion, the sliding and turning motion of the shutter is more reliable, when the lower end of the shutter slides along the front end of the lateral surface of the frame up and down and the upper end of the shutter slides along the upper end of the lateral surface of the frame front and back.

"Specifically, the first sliding groove includes a straight portion and an arc portion, the arc portion is curved in a direction away from the banknote port and is provided adjacent to the second sliding groove, and the second sliding groove is a straight groove, such that the enveloping space generated by the shutter when opening or closing the banknote port is smaller, thereby further creating a better condition for simplifying the structure of the shutter mechanism of the present application.

"Two first sliding portions are provided at two sides of the lower end of the shutter respectively, two second sliding portions are provided at two sides of the upper end of the shutter respectively, the first sliding portions and the second sliding portions are cylindrical, and the cylindrical first sliding portions and second sliding portions each are pivotally connected with a roller wheel. Due to the two first sliding portions provided at two sides and the two second sliding portions provided at two sides, the stress at various positions of the shutter is more even, thereby improving the accuracy and the reliability of the shutter when opening or closing the banknote port. Due to the roller wheel, the sliding of the shutter is more flexible and has smaller resisting force, such that the driving mechanism may more easily drive the shutter to open or close the banknote port.

"Preferably, the driving mechanism includes a conveying member and a driving assembly, the conveying member is provided at the upper end of the lateral surface of the frame in a front-back direction, an output end of the driving assembly is connected to the conveying member, and the second sliding portion is fixed on the conveying member, such that via the conveying member and the second sliding portion, the driving assembly may more easily drive the shutter to open or close the banknote port. Specifically, the driving mechanism further includes a second position sensor electrically connected to a controller of the financial self-service device, and a locking assembly. The second sliding portion is fixed on one end of the locking assembly, and the other end of the locking assembly is fixed on the conveying member. Two second position sensors are respectively provided at the upper end of the lateral surface of the frame in a front-back direction and are located outside two sides of the locking assembly respectively. A position of the locking assembly corresponds to one of the second position sensors when the shutter closes the banknote port, and the position of the locking assembly corresponds to the other one of the second position sensors when the shutter opens the banknote port, such that via the driving mechanism, the controller can accurately control the shutter to open or close the banknote port.

"More specifically, the driving assembly includes a motor, a driving gear, a driven gear, a driving shaft, a primary driving wheel and an auxiliary driving wheel. The driving shaft is pivotally connected to a rear of the upper end of the lateral surface of the frame, and protrudes out of the upper end of the lateral surface of the frame to form a mounting end. The primary driving wheel is mounted on the mounting end, and the auxiliary driving wheel is pivotally connected to a front of the upper end of the lateral surface of the frame at a position corresponding to the primary driving wheel. The conveying member is surroundingly provided at outside of the primary driving wheel and the auxiliary driving wheel, the motor is mounted on the frame, the driving gear is mounted on an output shaft of the motor, the driven gear is mounted on the driving shaft and is engaged with the driving gear, and a torque limiter is provided between the driving shaft and the driven gear. The above configuration may simplify the structure of the driving assembly, facilitate the dismounting and the maintenance, and further miniaturize the shutter mechanism of the present application on one hand; and avoid an excessive clamping force when the closing is overloaded, and prevent components from being impacted repeatedly when the opening is overloaded on the other hand, thereby ensuring the shutter mechanism of the present application working more reliably.

"Preferably, the locking mechanism includes a locking and driving assembly electrically connected to the controller, and a locking plate located above the banknote port and pivotally connected to the frame. The locking and driving assembly drives the locking plate to abut against and lock the shutter when the shutter closes the banknote port, such that when closing the banknote port, the shutter is in a locked state, thereby preventing violent pry or damaging force action to some extent and ensuring the security of the banknote inside the financial self-service device and the security of corresponding components of the shutter mechanism of the present application. Specifically, the locking mechanism further includes a first position sensor electrically connected to the controller and provided at the upper end of the lateral surface of the frame. One end of the locking plate is extended toward the banknote port to form a locking portion, and the other end of the locking plate is extended toward the first position sensor to form a sensing portion. A position of the sensing portion corresponds to the first position sensor, when the shutter closes the banknote port and the locking portion abuts against and locks the shutter. Due to the first position sensor, the controller can accurately control the locking mechanism to lock or loosen the shutter. Since the locking portion abuts and locks the shutter, a stress direction of the shutter is reasonable, thereby further ensuring the security of the banknote inside the financial self-service device and the security of corresponding structures of the shutter mechanism of the present application. More specifically, two locking portions are provided at two sides of the locking plate respectively, such that the locking force at various positions of the shutter is more even, thereby further increasing the locking force and meanwhile avoiding the deformation of the shutter caused by uneven stress.

"Compared to the prior art, the lower end of the shutter of the present application is slidably connected to the front end of the lateral surface of the frame in an up-down direction, the upper end of the shutter is slidably connected to the upper end of the lateral surface of the frame in a front-back direction, and the upper end of the shutter is driven by the driving mechanism to slide along the upper end of the lateral surface of the frame front and back, and meanwhile the lower end of the shutter is driven to slide along the front end of the lateral surface of the frame up and down, such that the shutter is driven by the driving mechanism to make rigid planar motion (i.e. combining the existing sliding manner, sliding back and forth in a certain plane, and pivoting manner of the shutter), which overcomes the disadvantage of the existing sliding shutter mechanism or the pivoting shutter mechanism that the space occupied by the shutter mechanism is relatively large due to the extremely huge enveloping space generated by the motion of the shutter. Therefore, the shutter mechanism of the present application can reduce the enveloping space generated by the motion of the shutter and can also reduce the space of the frame occupied by the shutter, such that the structure of the shutter mechanism of the present application is more compact.
