[0041] The utility model provides a kind of card reading equipment of card swiping type.

[0042] Please refer to Figures 1 to 4In an embodiment of the present application, the card swiping type card reading device comprises a body 10, a control circuit board, and at least one code disc structure 20. The body 10 is provided with an inner cavity 10a, a card swiping slot 10b, and an opening 10c. The opening 10c is in communication with the inner cavity 10a and the card swiping slot 10b. The control circuit board is installed in the inner cavity 10a. The code disc structure 20 is installed in the inner cavity 10a and electrically connected with the control circuit board. Part of the code disc structure 20 extends into the card swiping slot 10b from the opening 10c. When a card is inserted into the card swiping slot 10b to drive the code disc structure 20 to operate, the code disc structure 20 forwards the recorded linear velocity of the card to the control circuit board.

[0043] The body 10 is the structural basis of the card reading device, which includes the inner cavity 10a, the card swiping slot 10b, and the opening 10c. The inner cavity 10a is a space inside the body 10 for installing the control circuit board and other key components. The card swiping slot 10b is a channel for the card to be inserted and moved, and its design ensures that the card can pass smoothly. The opening 10c is a channel connecting the inner cavity 10a and the card swiping slot 10b, allowing part of the code disc structure 20 to extend from the inner cavity 10a into the card swiping slot 10b. The control circuit board is the brain of the card reading device, responsible for processing signals from the code disc structure 20 and executing corresponding control commands. It is installed in the inner cavity 10a of the body 10 and electrically connected with the code disc structure 20, receiving the linear velocity data of the card recorded by the code disc structure 20 and adjusting the card reading operation according to these data. The code disc structure 20 is one of the core components of the device, which is installed in the inner cavity 10a of the body 10 and electrically connected with the control circuit board. The code disc structure 20 includes a transmission shaft 21, a code disc 22, and a contact wheel 23. The transmission shaft 21 is a central shaft connecting the code disc 22 and the contact wheel 23, which is rotatably connected in the inner cavity 10a. The code disc 22 is drivingly connected with one end of the transmission shaft 21 for recording the movement of the card. The contact wheel 23 is drivingly connected with the other end of the transmission shaft 21 and partially extends into the card swiping slot 10b through the opening 10c to directly contact the card.

[0044] When the card is inserted into the card swiping slot 10b, it will contact the contact wheel 23, driving the contact wheel 23 to rotate, and then driving the transmission shaft 21 and the code disc 22 to move. The linear velocity data of the card recorded by the code disc structure 20 is transmitted to the control circuit board through electrical connection. The control circuit board adjusts the card reading operation according to these data, ensuring that the card information is read at the best time, improving the accuracy and efficiency of card reading.

[0045] The code disc structure 20 can accurately record the position and speed of the card, which means that the exact position of the card in the card slot 10b can be determined, and dynamic tracking and prediction of the image can be performed, ensuring that the real-time motion state of the card is considered in the image processing algorithm. In this way, the image sensor (such as a camera) can be controlled to capture images at the best time, i.e. when the card moves to the optimal reading position, which helps to improve the accuracy of image recognition, especially under dynamic conditions. The auxiliary parameters (such as linear speed) provided by the code disc structure 20 can simplify the design of the image processing algorithm. For example, when performing image correction or feature extraction, these parameters can be used to reduce the amount of data that needs to be processed, thereby reducing the complexity of the algorithm, which can speed up the development process and improve development efficiency.

[0046] Through the cooperative operation of the above-mentioned components, the moving speed and position of the card inserted into the card slot 10b are accurately obtained through the code disc structure 20, the introduction of the code disc structure 20 reduces the dependence on complex software algorithms, simplifies the software development process, reduces costs, and makes the card slot type card reading device adaptable to different card types and use conditions.

[0047] In an embodiment, please refer to Figure 3 and Figure 4 , the code disc structure 20 includes a transmission shaft 21, a code disc 22, and a contact wheel 23. The transmission shaft 21 is rotationally connected to the inner cavity 10a. The code disc 22 is in transmission connection with one end of the transmission shaft 21. The contact wheel 23 is in transmission connection with the other end of the transmission shaft 21, and part of the contact wheel 23 extends into the card slot 10b from the opening 10c. Wherein, the card inserted into the card slot 10b contacts the contact wheel 23, so that the transmission shaft 21 drives the code disc 22 to move.

[0048] The transmission shaft 21 is a key component in the code disc structure 20, which is responsible for transmitting power from the contact wheel 23 to the code disc 22. The transmission shaft 21 is usually made of a sturdy and durable material to ensure stability and reliability during long-term use. One end of the transmission shaft 21 is connected to the code disc 22, and the other end is connected to the contact wheel 23, forming a continuous power transmission path. The transmission shaft 21 is rotationally connected to the inner cavity 10a, which means it can rotate freely within the inner cavity 10a without interference from other components.

[0049] The code disc 22 is a component in transmission connection with one end of the transmission shaft 21, and its main function is to record the moving speed of the card. The code disc 22 is usually composed of precise scales or grooves, which work with sensors to accurately measure the rotational speed of the transmission shaft 21, thereby calculating the linear speed of the card. The design of the code disc 22 requires high precision to ensure the accuracy of the measurement results.

[0050] The contact wheel 23 is the component of the encoder structure 20 that directly contacts the card. It is connected to the other end of the drive shaft 21 and partially extends into the card slot 10b through the opening 10c. The contact wheel 23 is designed to take into account the friction and durability when in contact with the card to ensure accurate measurement over a long period of use. The outer wall of the contact wheel 23 can be provided with a rubber layer to increase the friction with the card, ensuring a stable detection signal while reducing wear and tear and extending the life of the device.

[0051] When the card is inserted into the card slot 10b, the contact wheel 23 first comes into contact with the card. The rubber layer design of the contact wheel 23 allows it to maintain good contact with the card, ensuring stable contact even if the insertion speed of the card varies. The rotation of the contact wheel 23 is transmitted to the encoder disk 22 through the drive shaft 21. The rotational connection of the drive shaft 21 ensures the continuity and stability of power transmission, which is not affected by other components in the inner cavity 10a. The encoder disk 22 rotates with the rotation of the drive shaft 21, and the scale or groove on it cooperates with the sensor to record the rotation speed of the encoder disk 22. This speed is directly proportional to the linear speed of the card, so the movement speed of the card can be measured by the rotation speed of the encoder disk 22. The speed data recorded by the encoder disk 22 is transmitted to the control circuit board through electrical connection. The control circuit board adjusts the card reading operation according to these data to ensure that the card information is read at the best time.

[0052] Through the cooperative operation of the above-mentioned components, the encoder structure 20 of the card swipe type card reading device is designed to accurately obtain the movement speed and position of the card, providing important operation parameters for the control circuit board, so that the device can adapt to different card types and use conditions, reducing the dependence on complex software algorithms, simplifying the software development process, and reducing costs.

[0053] In an embodiment, referring to Figure 3 and Figure 4 , the outer wall of the contact wheel 23 is provided with a rubber layer.

[0054] The contact wheel 23 is the component of the encoder structure 20 that directly contacts the card. Its function is to convert the physical movement of the card into measurable mechanical movement. The rubber layer on the outer wall of the contact wheel 23 is made of elastic material, and the main function of the rubber layer is to provide stable contact force to ensure good contact between the contact wheel 23 and the card, even if the insertion speed of the card varies. It can maintain stable connection. In addition, the rubber layer can also act as a buffer to reduce the impact caused by the insertion of the card, protecting the contact wheel 23 and the card from damage.

[0055] In an embodiment, referring to Figure 3 and Figure 4The outer circumferential wall of one end of the transmission shaft 21 is provided with a friction tooth surface 21a, which is in contact with the contact wheel 23.

[0056] The friction tooth surface 21a is a special structure provided on the outer circumferential wall of one end of the transmission shaft 21, which is a series of tooth-shaped protrusions designed to increase the friction between the contact wheel 23. The contact design of these tooth surfaces with the contact wheel 23 can increase the friction and ensure that the transmission shaft 21 stably drives the code disc 22, improving the accuracy of speed detection.

[0057] By providing a friction tooth surface 21a on the outer circumferential wall of one end of the transmission shaft 21 and in contact with the contact wheel 23, the friction tooth surface 21a provides stable friction, ensuring that the code disc structure 20 can accurately measure the linear speed of the card, improving the accuracy and reliability of card reading. Secondly, the design of the friction tooth surface 21a reduces errors caused by poor contact or sliding, improving the stability of speed measurement.

[0058] In an embodiment, referring to Figure 3 and Figure 4 , a bearing is provided between the end of the transmission shaft 21 away from the contact wheel 23 and the cavity wall of the inner cavity 10a.

[0059] The transmission shaft 21 is the central shaft connecting the code disc 22 and the contact wheel 23, responsible for transmitting the power of the contact wheel 23 to the code disc 22, thereby realizing the measurement of the linear speed of the card. The bearing is a key component for reducing friction between the transmission shaft 21 and the cavity wall of the inner cavity 10a, which allows the transmission shaft 21 to rotate freely in the inner cavity 10a while bearing the force transmitted by the contact wheel 23. The main function of the bearing is to convert sliding friction into rolling friction, significantly reducing energy loss due to friction, thereby improving the energy efficiency of the device. In addition, the bearing can also bear a certain load, ensuring the stability of the transmission shaft 21 under high load.

[0060] In an embodiment, referring to Figure 3 and Figure 4 , the card swiping type card reading device further comprises two code disc structures 20, both of which are installed in the inner cavity 10a and are arranged in a spaced manner along the extension direction of the card swiping slot 10b.

[0061] Both code disc structures 20 are installed in the inner cavity 10a of the device and are arranged in a spaced manner along the extension direction of the card swiping slot 10b. Such a design means that there are code disc structures 20 at both ends of the card swiping slot 10b, which can detect the speed of the card when it enters and leaves the card swiping slot 10b, respectively. Each code disc structure 20 includes a transmission shaft 21, a code disc 22 and a contact wheel 23, which are electrically connected with the control circuit board and are responsible for converting the physical movement of the card into an electrical signal to record the linear speed of the card.

[0062] By setting two code disc structures 20 at both ends of the card swiping slot 10b, the motion state of the card in the entire card swiping slot 10b, including the starting, accelerating, uniform speed, and decelerating stages, can be more accurately measured, thereby improving the accuracy and reliability of card reading. Secondly, this design enables the device to adapt to cards of different speeds, whether fast or slow insertion, and can accurately read data, enhancing the adaptability and flexibility of the device. In addition, the design of the double code disc structure 20 also improves the stability of the device, and even in the case of uneven or biased card insertion, the data of the two code disc structures 20 can be compared to correct the card reading error and ensure the consistency of card reading.

[0063] In an embodiment, referring to Figure 3 and Figure 4 , the body 10 includes a shell 11 and at least one fixing frame 12, the shell 11 is provided with an inner cavity 10a, a card swiping slot 10b, and an opening 10c; the fixing frame 12 is fixed to the cavity wall of the inner cavity 10a, and the code disc structure 20 is detachably connected to the fixing frame 12.

[0064] The shell 11 is the external structure of the card swiping type card reading device, which is composed of an inner cavity 10a, a card swiping slot 10b, and an opening 10c. The shell 11 not only provides the appearance of the device, but also protects the internal components from the external environment. The inner cavity 10a is the space inside the shell 11, used to accommodate the control circuit board, the code disc structure 20, and other key components. The card swiping slot 10b is the channel for card insertion and movement, while the opening 10c is the channel connecting the inner cavity 10a and the card swiping slot 10b, allowing part of the components of the code disc structure 20 to extend from the inner cavity 10a to the card swiping slot 10b. The fixing frame 12 is a structure installed on the cavity wall of the inner cavity 10a, used to fix the code disc structure 20. The design of the fixing frame 12 ensures the stability of the code disc structure 20 during operation, preventing displacement due to vibration or impact, thereby ensuring the accuracy and reliability of card reading. The code disc structure 20 is a key component in the card swiping type card reading device for measuring the linear speed of the card, which includes a transmission shaft 21, a code disc 22, and a contact wheel 23. The code disc structure 20 is detachably connected to the fixing frame 12, which makes the installation and maintenance of the code disc structure 20 more convenient.

[0065] Through this body 10 design, the inner cavity 10a of the shell 11 provides sufficient space and protection for internal components, ensuring the compactness and durability of the device. Secondly, the use of the fixing frame 12 improves the stability of the code disc structure 20, reducing vibration and displacement during operation, and improving the accuracy of speed measurement. In addition, the design of the card swiping slot 10b and the opening 10c enables the code disc structure 20 to smoothly contact the card, ensuring efficient power transmission and accurate speed measurement.

[0066] In an embodiment, referring to Figure 3 andFigure 4 The fixing frame 12 comprises a main body 121, a mounting plate 122, a connecting piece 123 and two springs 124. The main body 121 is fixed to the cavity wall of the inner cavity 10a. The main body 121 is provided with a mounting opening 121a and at least two mounting protrusions 121b. The two mounting protrusions 121b are spaced apart from the mounting opening 121a. The code disc structure 20 is mounted on the mounting plate 122. One end of the mounting plate 122 is provided with two mounting holes 122a. Each mounting protrusion 121b is inserted into a mounting hole 122a. The other end of the mounting plate 122 extends from the mounting opening 121a. The connecting piece 123 is threadedly connected to the mounting protrusion 121b, so that the mounting plate 122 is detachably connected to the main body 121. Each spring 124 is sleeved on a mounting protrusion 121b, and the two ends of the spring 124 are elastically abutted with the mounting plate 122 and the connecting piece 123, respectively.

[0067] The main body 121 is provided with a mounting opening 121a and at least two mounting protrusions 121b. The mounting protrusions 121b are spaced apart from the mounting opening 121a, providing accurate positions for the installation of the mounting plate 122. The mounting plate 122 is a planar component on the fixing frame 12 for mounting the code disc structure 20. One end of the mounting plate 122 is provided with two mounting holes 122a for cooperation with the mounting protrusions 121b. The other end of the mounting plate 122 extends from the mounting opening 121a to connect with the code disc structure 20. The design of the mounting plate 122 allows the code disc structure 20 to be stably mounted thereon and to be adjusted in position with the movement of the mounting protrusions 121b in the mounting holes 122a. The connecting piece 123 is a component in the fixing frame 12 for detachably connecting the mounting plate 122 to the main body 121. It is connected to the mounting protrusions 121b by threads, allowing the mounting plate 122 to be easily detached from the main body 121 when needed, facilitating the installation, maintenance or replacement of the code disc structure 20. The two springs 124 in the fixing frame 12 are sleeved on the two mounting protrusions 121b. The two ends of the springs 124 are elastically abutted with the mounting plate 122 and the connecting piece 123, respectively. The springs 124 provide elastic support between the mounting plate 122 and the main body 121, reducing the influence of external vibration or impact on the code disc structure 20 and maintaining the stability of the code disc structure 20.

[0068] Firstly, the spring 124 provides the necessary elastic support, which enables the fixing frame 12 to absorb the forces generated due to external vibrations or impacts, reducing the impact of these forces on the code disc structure 20, thereby protecting the code disc structure 20 from damage. This elastic support also helps to reduce the vibration of the code disc structure 20 during operation, improving the accuracy and reliability of card reading. Secondly, the use of the spring 124 enables the fixing frame 12 to adapt to different installation conditions and minor changes in the code disc structure 20. Since the spring 124 can stretch within a certain range, it can compensate for installation errors or minor size differences between components, ensuring that the code disc structure 20 always maintains the correct position and posture. The use of the spring 124 also improves the durability of the fixing frame 12. Since the spring 124 material generally has good fatigue resistance, it can maintain stable elasticity during long-term use, reducing the risk of damage due to metal fatigue.

[0069] The use of the mounting plate 122 in combination with the mounting protrusion 121b provides precise position adjustment, enabling the code disc structure 20 to be precisely positioned as needed. In addition, the threaded connection design of the connecting piece 123 enables the connection between the mounting plate 122 and the main body 121 to be both firm and detachable, facilitating the installation and maintenance of the code disc structure 20.

[0070] In an embodiment, referring to Figure 3 and Figure 4 , the mounting plate 122 includes a vertical plate and a horizontal plate connected to one end of the vertical plate, with the vertical plate and the horizontal plate arranged vertically; the vertical plate is provided with two mounting holes 122a at the end away from the horizontal plate, and the horizontal plate extends from the mounting hole 121a and is arranged in a spaced manner with the main body 121; and the vertical plate along the movement range on the mounting protrusion 121b is consistent with the compression range of the spring 124.

[0071] The vertical plate is the vertical part of the mounting plate 122, which is fixed to the main body 121 of the inner cavity 10a, serving as the main support structure of the mounting plate 122. The design of the vertical plate needs to be strong enough to withstand the weight and force of the code disc structure 20 in operation. The end of the vertical plate away from the horizontal plate is provided with two mounting holes 122a, which are used to install the insertion of the protruding column 121b, so that the code disc structure 20 can be fixed on the mounting plate 122. The horizontal plate is the horizontal part of the mounting plate 122, connected to one end of the vertical plate. The design of the horizontal plate is used to fix the code disc structure 20, which extends from the mounting port 121a and is spaced apart from the main body 121, ensuring that the code disc structure 20 can be stably installed in the appropriate position. The two mounting holes 122a on the vertical plate are used to install the protruding column 121b, and the position and size of the mounting holes 122a are precisely designed to ensure that the protruding column 121b can be accurately inserted and can withstand the force generated by the code disc structure 20 in operation. The spring 124 is sleeved on the protruding column 121b, and the two ends are elastically abutted with the mounting plate 122 and the connecting piece 123 respectively. The design of the spring 124 allows the moving range of the vertical plate along the protruding column 121b to be consistent with the compression range of the spring 124, providing accurate adjustment and buffering.

[0072] The design of the mounting hole 122a allows the code disc structure 20 to be flexibly adjusted in position to adapt to different installation requirements and card types. In addition, the design of the horizontal plate extending from the mounting port 121a allows the code disc structure 20 to be stably fixed in the appropriate position, reducing the reading error caused by improper installation. At the same time, the use of the spring 124 provides the necessary elastic support for the code disc structure 20, reducing the influence of external force on the code disc structure 20 and improving the anti-vibration performance of the equipment.

[0073] In an embodiment, please refer to Figure 3 and Figure 4 The card swiping slot 10b has two card swiping ports, which are located at the two ends of the card swiping slot 10b arranged in the extension direction, and the card swiping ports are flared card swiping ports.

[0074] The card swiping slot 10b is a channel for card insertion and passing, and its design must ensure that the card can be smoothly inserted and removed. The two card swiping ports of the card swiping slot 10b are located at its two ends, and this design provides the function of bidirectional insertion, improving the convenience of use for users, who can insert the card from either end without being restricted by direction.

[0075] The flared card swiping port refers to the design of the end of the card swiping port being slightly expanded. The design of the flared card swiping port reduces the resistance and error during card insertion, improves the accuracy of insertion, and reduces the reading failure caused by improper insertion.

[0076] In an embodiment, please refer toFigure 3 And Figure 4 The card swiping type card reading device further comprises a slider, which is slidingly connected to the bottom of the card swiping slot 10b; the slider is provided with a card connecting slot, and an elastic layer is arranged on the card connecting slot, which is used for elastically abutting against the card.

[0077] The slider is an important mechanical component in the card swiping type card reading device, which is slidingly connected to the bottom of the card swiping slot 10b. The main function of the slider is to directly contact the card, guide the card to move smoothly in the card swiping slot 10b, and reduce the friction between the card and the card swiping slot 10b. The card connecting slot is a specific slot designed on the slider, which is used to receive the edge of the card. The shape and size of the card connecting slot are matched with the edge of the card, which ensures that the card can be correctly guided and positioned. The elastic layer is an elastic material layer arranged on the card connecting slot, which is used for elastically abutting against the card. The material of the elastic layer usually has high elasticity and wear resistance, which can provide buffer when the card is inserted and extracted, reducing damage to the card and the device.

[0078] When the card is inserted into the card swiping slot 10b, the card connecting slot on the slider first contacts the edge of the card. The design of the card connecting slot ensures that the card can move smoothly along the predetermined track. The card connecting slot of the slider guides the card to move in the card swiping slot 10b, and the elastic layer provides necessary elastic support to ensure that the card maintains correct position and direction during movement. The elastic abutment of the elastic layer and the card reduces the direct friction between the card and the card swiping slot 10b, reduces the friction, and makes the card pass through the card swiping slot 10b more smoothly.

[0079] As the card moves, the card abutting against the elastic layer of the card connecting slot of the slider is in contact with the contact wheel 23 more quickly, further accelerating the card reading speed of the card swiping type card reader, thereby improving the working efficiency of the card swiping type card reader.

[0080] In an embodiment, referring to Figure 3 And Figure 4 Figure 3 Figure 4 The moving track of the slider is located below the opening 10c.

[0081] The opening 10c is a passage on the body 10, which connects the inner cavity 10a and the card swiping slot 10b, and allows part of the components of the code disc structure 20 to extend from the inner cavity 10a to the card swiping slot 10b. The position and size of the opening 10c need to be carefully designed to ensure that the code disc structure 20 can pass through smoothly, without affecting the movement of the slider.

[0082] When the card is inserted into the card slot 10b, the card slot of the slider first contacts the edge of the card. The elastic layer of the slider provides elastic support for the card, ensuring smooth movement of the card along the predetermined track. With the insertion of the card, the slider moves along the bottom of the card slot 10b, and its movement trajectory is designed below the opening 10c, so that the movement of the slider will not be interfered by the extension part of the code disc structure 20. The movement trajectory of the slider is below the opening 10c, which means that the slider and the working area of the code disc structure 20 are independent of each other, reducing direct friction and potential jamming. The movement of the slider is sensed by the code disc structure 20, which then transmits the speed information to the control circuit board, which adjusts the card reading operation according to these data to ensure that the card information is read at the best time.

[0083] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation or direct / indirect application in other related technical fields within the technical concept of the present application, as described in the present application and the drawings, is included in the patent protection scope of the present application.
