Description

Technical Field

[0001] This utility model relates to the field of card issuing machine technology, and in particular to a telescopic mechanism for a card issuing machine. Background Technology

[0002] Most highways nowadays are equipped with unattended automatic card dispensers. Drivers only need to press a button, and the dispenser will automatically issue cards, which greatly improves card issuance efficiency and saves manpower.

[0003] Existing automatic card dispensers generally include a card storage box, a card dispensing mechanism, a reader / writer, and a conveying mechanism. For example, CN203706269U describes a telescopic mechanism for a card dispenser, including a card storage box and a conveying mechanism. The telescopic mechanism is positioned between the card storage box and the conveying mechanism and is used to control the extension or retraction of the conveying mechanism. The telescopic mechanism includes an electro-energized III, a synchronous belt V, a synchronous pulley V, a screw, and a telescopic module. This telescopic mechanism can detect the distance between the vehicle and the dispenser. When the driver parks too far from the dispenser, the front half of the dispenser automatically extends forward to facilitate the driver pressing the button, taking the card, and swiping it. After taking the card or successfully swiping it, the automatic card dispenser retracts to its original position. However, due to the high dust levels on highways, the screw, as a core transmission component, is highly susceptible to stubborn dirt buildup in the contact area between its spiral grooves and the moving parts during long-term use. As usage time increases, this dust not only exacerbates frictional wear between the screw and the matching nut, but also causes the lubricating grease to fail quickly, resulting in jamming and jerking during the extension and retraction adjustment process, and even causing motor overload failure. This greatly weakens the stability and reliability of the card issuer and seriously affects the normal and efficient operation of the highway toll collection system.

[0004] Therefore, there is an urgent need to design a telescopic mechanism for a card issuing machine that can effectively remove dust adhering to the outside of the screw of the card issuing assembly. The entire cleaning process does not require additional control devices, which not only improves cleaning efficiency but also effectively reduces costs and saves energy. It also effectively ensures the smooth operation of the screw and ensures the stability and reliability of the telescopic adjustment of the card issuing machine. Summary of the Invention

This telescopic mechanism can effectively remove dust adhering to the outside of the screw of the card issuing assembly, and the entire cleaning process does not require additional control devices. It not only improves cleaning efficiency, but also effectively reduces costs and saves energy, effectively ensures the smooth operation of the screw, and ensures the stability and reliability of the telescopic adjustment of the card issuing machine.

[0019] Preferred embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

These terms are only used to distinguish information of the same type from one another.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] During long-term use, the screw, as a core transmission component, is highly susceptible to persistent dust accumulation due to environmental factors. This dust buildup forms stubborn deposits on the screw's spiral grooves and in the contact area with the moving parts. Over time, this dust not only exacerbates frictional wear between the screw and the matching nut but also causes rapid deterioration of the lubricating grease. This results in jamming and jerking during adjustment, and may even lead to motor overload, significantly weakening the stability and reliability of the card dispenser and severely impacting the normal and efficient operation of the highway toll collection system.

[0023] To address the aforementioned issues, this application provides a telescopic mechanism for a card issuing machine. This telescopic mechanism effectively removes dust adhering to the outside of the screw of the card issuing assembly, and the entire cleaning process does not require additional control devices. This not only improves cleaning efficiency but also effectively reduces costs and saves energy, ensuring smooth operation of the screw and guaranteeing the stability and reliability of the card issuing machine's telescopic adjustment.

[0024] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. Example

[0025] Please see Figures 1-5 The telescopic mechanism of the card issuing machine of this application includes a fixing component 1, a card issuing component 2, and a cleaning component 3. The card issuing component 2 is disposed on the fixing component 1 and is used to issue access cards. The cleaning component 3 is disposed on the side of the card issuing component 2 and is used to remove dust from the card issuing component 2.

[0026] Specifically, the fixing component 1 includes a first side plate 11, a second side plate 12, and a base 13. The base 13 is generally U-shaped. The first side plate 11 and the second side plate 12 are parallel and symmetrically arranged at both ends of the base 13 and are fixedly connected to the base 13. That is, the first side plate 11, the second side plate 12, and the base 13 can form a frame with an opening at the top and a receiving cavity, which facilitates fixing and supporting the hair clip component 2 and the cleaning component 3.

[0027] The hairpin assembly 2 includes a drive motor 21, a screw 22, a threaded plate 23, and a hairpin body 24. The drive motor 21 is disposed on one side of the first side plate 11. The screw 22 is rotatably disposed on the first side plate 11 and the second side plate 12 via a rotating shaft and is connected to the output end of the drive motor 21, i.e., one end of the screw 22 is rotatably disposed on the first side plate 11 and the other end is rotatably disposed on the second side plate 12. The threaded plate 23 is sleeved on the screw 22 and threadedly connected to the screw 22. For example, the threaded plate 23 has a threaded through hole. By passing the screw 22 through the threaded through hole, the threaded plate 23 is threadedly connected to the screw 22. The hairpin body 24 is disposed at the top end of the threaded plate 23 and is fixedly connected to the threaded plate 23. When the user presses the card removal button, the drive motor 21 starts, driving the screw 22 to rotate. This causes the threaded plate 23, which is threaded to it, to move along the extension direction of the screw 22 through axial pressure and friction, thereby driving the card issuing body 24 to move synchronously, making it easier for the user to remove the card.

[0028] Furthermore, to facilitate card retrieval for users, the card dispenser's telescopic mechanism also includes a radar probe 4, which is mounted on the card dispenser body 24 and used to detect the vehicle's parking distance. For example, when a user stops and presses the card retrieval button, the radar probe 4 detects the distance between the vehicle and the card dispenser, and the drive motor 21 moves the card dispenser body 24, ensuring the distance between the card dispenser body 24 and the driver is within a preset safe card retrieval distance. This allows the position of the card dispenser body 24 to be adjusted in real time according to the driver's parking distance, further improving the convenience and accuracy of card retrieval.

[0029] The cleaning component 3 includes a cleaning transmission component and a cleaning brush 32. The cleaning transmission component is respectively disposed on the hairpin component 2 and the fixing component 1, and is used to drive the cleaning brush 32 to rotate. The cleaning brush 32 is rotatably disposed on the side of the hairpin component 2 and can contact the hairpin component 2 to remove dust from the hairpin component 2. Specifically, the cleaning transmission component includes a fixing plate 311, a transmission rod 312, a transmission gear 313, and a transmission rack 314. The fixing plate 311 is horizontally disposed at the bottom end of the threaded plate 23 and is fixedly connected to the threaded plate 23, that is, the fixing plate 311 and the threaded plate 23 are perpendicular to each other. The transmission rod 312 is rotatably mounted on the fixed plate 311, with both ends extending away from the fixed plate 311. The transmission gear 313 is located at the bottom end of the transmission rod 312, the cleaning brush 32 is located at the top end of the transmission rod 312, and the transmission rack 314 is mounted on the base 13 and meshes with the transmission gear 313. For example, two transmission rods 312, two transmission gears 313, two cleaning brushes 32, and two transmission racks 314 are provided. The two transmission rods 312, two transmission gears 313, and two cleaning brushes 32 are respectively located on both sides of the screw 22, with the cleaning brush 32 contacting the surface of the screw 22. The two transmission racks 314 are symmetrically arranged on opposite sides of the base 13. When the threaded plate 23 moves along the extension direction of the screw 22, it drives the fixed plate 311 and the transmission gear 313 to move synchronously along the extension direction of the screw 22. Since the transmission rack 314 meshing with the transmission gear 313 is fixed, when the transmission gear 313 moves, the transmission rack 314 drives the transmission gear 313 to rotate, which in turn drives the transmission rod 312 rotatably connected to it to rotate synchronously, and finally drives the cleaning brush 32 to rotate synchronously, thereby removing the dust on the screw 22 through the bristles on the cleaning brush 32.

[0030] Furthermore, to improve the stability of the movement of the card issuing body 24 and the cleaning brush 32, the cleaning transmission assembly also includes a slider 315; the base 13 is provided with a strip-shaped groove 316; the slider 315 is slidably disposed in the strip-shaped groove 316 and fixedly connected to the threaded plate 23. Preferably, both the slider 315 and the strip-shaped groove 316 are arc-shaped. By setting the slider 315 and the strip-shaped groove 316 to arc shapes, compared with a square structure, the arc-shaped structure provided in this application can effectively reduce the friction between the slider 315 and the strip-shaped groove 316, making the slider 315 slide more smoothly, and further improving the smoothness and stability of the card issuing machine operation.

[0031] Working principle: When the user stops the car and presses the card dispensing button, the radar probe 4 detects the distance between the vehicle and the card dispensing device, then drives the motor 21 to start, causing the screw 22 to rotate. This, through axial pressure and friction, causes the threaded plate 23, which is threaded to it, to move along the extension direction of the screw 22, thereby causing the card dispensing body 24 to move synchronously. This ensures that the distance between the card dispensing body 24 and the driver is within a preset safe card dispensing distance, making it convenient for the user to retrieve the card. When the threaded plate 23 moves along the extension direction of the screw 22, the transmission rack 314, which meshes with the transmission gear 313, is fixed. Therefore, when the transmission gear 313 moves, the transmission rack 314 drives the transmission gear 313 to rotate, thereby causing the transmission rod 312, which is rotatably connected to it, to rotate synchronously. Finally, the cleaning brush 32 rotates synchronously, thereby removing dust from the screw 22 through the bristles on the cleaning brush 32.

[0032] In this embodiment, the telescopic mechanism of the card issuing machine includes a card issuing component, a fixing component, and a cleaning component. By incorporating the cleaning component, dust on the screw can be removed by the rotation of the cleaning brush, effectively preventing jamming or jerking during telescopic adjustment caused by dust accumulation on the screw. Through the linkage of the screw, transmission gear, transmission rod, and transmission rack, the transmission gear and the cleaning brush can rotate synchronously during the movement of the threaded plate. The entire process requires only one drive motor to simultaneously move the card issuing body and rotate the cleaning brush, greatly simplifying the structure and reducing energy consumption. By making the slider and the strip-shaped groove arc-shaped, the friction between the slider and the strip-shaped groove is effectively reduced, making the slider slide more smoothly and further improving the smoothness and stability of the card issuing machine's operation. Compared with existing technologies, the solution provided in this application can effectively remove dust adhering to the outside of the screw of the card issuing assembly, and the entire cleaning process does not require additional control devices. This not only improves cleaning efficiency, but also effectively reduces costs and saves energy, effectively ensuring the smooth operation of the screw and ensuring the stability and reliability of the card issuing machine's telescopic adjustment. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0033] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
