Description

Technical Field

[0001] The present application relates to a slipping mechanism, and in particular to a purely mechanical slipping mechanism. Background Art

[0002] A banknote door is a movable door provided on a cash slot for taking out and putting in banknotes after opening. It is widely used in cash slots for taking out and putting in banknotes, for example, on ATM machines. For example, when a customer needs to withdraw money from an ATM, after the screen operation is completed, the ATM will spit banknotes of the desired amount into the cash slot. The cash slot will then open the banknote door of the cash slot electronically under the control command of the system, exposing the banknotes therein for the customer to withdraw.

[0003] Generally, the banknote door will automatically close after being opened for a certain period of time, regardless of whether the customer withdraws banknotes. These operations, such as opening and closing the banknote slot, are currently completed electronically, which uses many components, has a relatively complex overall structure, and has poor reliability.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present application is to provide a sliding mechanism that completely relies on a pure mechanical structure to open and close the banknote door.

[0012] The driving mechanism may drive the rotating shaft to rotate the shaped wheel (preferably, the first rotating wheel and the shaped wheel) through a synchronous belt; or the rotating shaft may be installed on a driving shaft of the driving mechanism and rotate with the driving shaft.

[0013] In another preferred embodiment, the mechanical slip mechanism further comprises a second rotating wheel, and the second rotating wheel drives the first rotating wheel to rotate.

[0014] In a more preferred embodiment, the second rotating wheel and the first rotating wheel are both gears, and the teeth of the second rotating wheel and the first rotating wheel are meshed with each other, the driving mechanism drives the second rotating wheel to rotate, and the second rotating wheel drives the first rotating wheel to rotate through the meshing gears.

[0018] Preferably, the follower plate is closely attached to one end of the outer edge of the special-shaped wheel, and is closely attached to the outer edge of the special-shaped wheel under the action of an elastic mechanism.

[0026] The present application provides a mechanical sliding mechanism. To make the purpose, technical solution and effect of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Example 1

[0028] In a preferred application embodiment of the mechanical slip mechanism of the present application, the slip mechanism includes a shaped wheel 3, and the structure diagram of the outer edge curve of the shaped wheel 3 is as follows: Figure 1-3 As shown, it is composed of two concentric arcs connected end to end, including a first arc 31 with a larger diameter and a second arc 32 with a smaller diameter, and the two arcs are smoothly connected by a smooth curve, and the smooth curve is preferably a spline curve 33, especially a spline curve of more than three degrees, which can ensure that the curvature of the curve of the outer edge of the shaped wheel 3 is smooth as a whole, including the curvature of the curve transitioning from the second arc 32 to the spline curve 33 and the curvature of the curve transitioning from the spline curve 33 to the first arc 31, or the change is not drastic. The shaped wheel 3 is fixed to a fixed frame 6 through a rotating shaft 13 and can rotate around the rotating shaft 13.

[0029] In one embodiment of the present application, the shaped wheel 3 can be directly fixedly connected to the output shaft of the driving mechanism and receive the driving rotation of the driving mechanism. For example, the shaped wheel 3 is located on one side of the fixing frame 6, and a motor is provided on the other side, and the rotating shaft 13 passes through the fixing frame and is connected to the driving shaft of the motor on the other side, or the motor driving shaft passes through the fixing frame 6 and is connected to the rotating shaft 13, and the rotation of the motor driving shaft drives the shaped wheel to rotate.

[0030] Alternatively, the special-shaped wheel 3 is provided with a driven wheel, and the driving shaft of the driving mechanism (such as a motor) is provided with a driving wheel. The driving wheel and the driven wheel are connected by a synchronous belt, thereby driving the driven wheel to rotate and driving the special-shaped wheel to rotate.

[0031] The sliding mechanism disclosed in the present application is preferably, but not limited to, applied to opening or closing a cash slot on an ATM machine, wherein the sliding mechanism drives a slave plate to open or close the cash door of the cash slot. Figure 3 As shown, under the action of the elastic mechanism (preferably a spring 43), the slave plate 4 keeps one end in close contact with the outer edge of the shaped wheel 3, that is, in close contact with the first arc 31 or the second arc 32 or the spline curve 33. Moreover, when the shaped wheel 3 rotates, under the joint action of the outer edge of the shaped wheel 13 and the elastic mechanism, the part of the slave plate 4 in close contact with the outer edge will move along the radial direction of the shaped wheel 3 as the radius of the shaped wheel 3 changes, so that the part of the slave plate 4 away from the outer edge will also move accordingly. The shaped wheel rotates, and when the first arc 31 begins to contact the slave plate 4, due to the larger radius of the first arc 31, the slave plate 4 is pushed outwards under the action of the first arc 31. The shaped wheel 3 continues to rotate until the first arc 31 leaves the slave plate 4, and during this process, the slave plate 4 remains stationary. The shaped wheel 3 continues to rotate, and when the follower plate 4 leaves the first arc 31, in the process from the spline curve 33 to the second arc 32, the arc radius is reduced, so the follower plate 4 is pushed inward by the elastic component; the follower plate 4 stops moving after contacting the second arc 32, and the shaped wheel stops rotating or continues rotating, and the follower plate 4 remains stationary before leaving the second arc 32.

[0032] The slave plate 4 can be connected to the banknote door 5 by one end thereof, preferably the end away from the outer edge, so that the banknote door 5 can be pulled or pushed to open or close by the movement of the slave plate 4 in a rotating or fixed connection manner. In a preferred embodiment, the schematic diagram of the way in which the slave plate 4 drives the banknote door 5 to move is as shown in Figure 5 As shown, the slave plate 4 is rotatably fixed on the fixing frame 6, and the lower end of the slave plate 4 is connected to the lower end of the banknote door 5, which can be a fixed connection or a movable connection, preferably a movable connection, so as to further increase the movement smoothness of the banknote door 5. When the slave plate 4 generates a rotation or other movement under the joint action of the special-shaped wheel 3 and the elastic component, Figure 5 The upper end of the slave plate 4, i.e., the end close to the outer edge of the special-shaped wheel 3, is pushed out by the first arc 31 and moves to the right during the process of moving from the second arc 32 to the first arc 31, and the other end of the slave plate 4 moves to the left together with the lower end of the banknote door 5 connected thereto, opening the banknote door 5 and exposing the cash slot for the user to take out and put in banknotes.

[0033] Because the curvature of the curve of the outer edge of the special-shaped wheel 3 has been set not to change dramatically, this ensures that the movement of the slave plate 4 will not change dramatically, that is, it ensures that the opening and closing of the banknote door 5 are very smooth without any sudden movements.

[0034] In this embodiment, the lengths of the first arc and the second arc are calculated by multiplying the opening time of the banknote gate 5 by the rotation speed of the shaped wheel 3. Because in this embodiment, the first arc 31 corresponds to the opening process of the banknote gate 5, after setting the opening time of the banknote gate 5, the arc length of the first arc 31 can be obtained by multiplying the rotation speed of the shaped wheel 3. The length of the second arc 33 can be calculated by subtracting the arc length of the first arc 31 from the total circumference of the shaped wheel 3 and the length of the smooth curve used to connect the two segments.

[0035] The present application provides a sliding mechanism, which can be used to automatically open and close a banknote door 5 of a cash slot by rotating a shaped wheel 3 which is formed by two concentrically arranged arcs of different radii and smoothly connected. It completely relies on a pure mechanical structure without the need for any electronic components, has a simple structure and high reliability.

[0036] Example 2

[0037] In a more preferred embodiment of the present application, Figure 2A and Figure 2B As shown, the shaped wheel 3 is coaxially arranged on the rotating shaft 13 with the first rotating wheel 1, and rotates with the first rotating wheel 2. At this time, the first rotating wheel 1 is arranged, especially the first rotating wheel 1 with a heavier mass, which can increase the rotation smoothness of the shaped wheel 3, thereby increasing the operation smoothness of the entire slip mechanism. The shaped wheel 3 is arranged parallel to the first rotating wheel 1, referring to Figure 2B The special-shaped wheel 3 protrudes from the plane where the first rotating wheel 1 is located, and the special-shaped wheel 3 can form an integral structure with the first rotating wheel 1.

[0038] In a more preferred embodiment, if Figure 3 As shown, a second rotating wheel 2 can also be arranged on the fixing frame 6, and the rotation of the second rotating wheel 2 drives the first rotating wheel 1 to rotate. The advantage of setting the second rotating wheel 2 is that the rotation speed of the special-shaped wheel 3 can be controlled by adjusting the different ratios of the diameters of the second rotating wheel 2 and the first rotating wheel 1. Of course, it is generally a deceleration setting, that is, in a common design, the diameter of the first rotating wheel 1 should be larger than the diameter of the second rotating wheel 2. Therefore, on the one hand, the rotation speed of the special-shaped wheel 3 can be reduced, and on the other hand, the output torque of the special-shaped wheel 3 can be increased.

[0039] The first rotating wheel 1 and the second rotating wheel 2 can be driven by a synchronous belt or by a synchronous belt. Figure 3 The first rotating wheel 1 and the second rotating wheel 2 are both set as gears, and the rotational power is transmitted through the mutual meshing between the two. The advantage of setting the matching mode as a synchronous belt drive mode is that it is convenient to adjust the rotation speed and disassemble and maintain; the advantage of setting the matching mode as a gear meshing transmission mode is that the space volume occupied by the entire sliding mechanism can be reduced, thereby facilitating installation and use, especially when installed in a device with a smaller space.

[0040] The specific embodiments of the present invention are described in detail above, but they are only examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions made to the present invention are also within the scope of the present invention. Therefore, the equalization changes and modifications made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
