[0042] The invention provides an insertion type card reading device.

[0043] See also Figures 1 to 4In one embodiment of the present invention, the plug-in card reader device includes a body 10, a control circuit board and at least one code disk structure 20, the body 10 is provided with an inner cavity 10a, a card insertion slot 10b and a first opening, the first opening is connected with the inner cavity 10a and the card insertion slot 10b; the control circuit board is installed in the inner cavity 10a; the code disk structure 20 is installed in the inner cavity 10a and is electrically connected to the control circuit board; and part of the code disk structure 20 extends from the first opening into the card insertion slot 10b; wherein, when a card is inserted into the card insertion slot 10b, the code disk structure 20 is driven to run, so that the code disk structure 20 forwards the recorded linear velocity of the card to the control circuit board.

[0044] The main body 10 is the basic structure of the plug-in card reader device. It is made of strong and durable materials to ensure stability and reliability during long-term use. The main body 10 is designed with an inner cavity 10a. This inner cavity 10a is the core area of ​​the device and is used to accommodate the control circuit board and other key components. The front of the main body 10 is provided with a card slot 10b, which is where the user inserts the card. Its design is convenient for user operation and can effectively protect the card from damage. In addition, the main body 10 is also provided with a first opening, which connects the inner cavity 10a and the card slot 10b, providing the necessary channel for the code disk structure 20.

[0045] The control circuit board is the core control unit of the plug-in card reader device. It is responsible for processing the data from the code disk structure 20 and converting it into readable information. The control circuit board is installed in the inner cavity 10a of the body 10 and is electrically connected to the code disk structure 20 to ensure the accuracy and real-time performance of data transmission. The circuit board integrates advanced microprocessors and memory, which can quickly process and store large amounts of data. In addition, the control circuit board also has a self-diagnosis function, which can monitor the device status in real time to ensure that the device operates in the best condition.

[0046] The code disk structure 20 is one of the key components of the plug-in card reader device, which is responsible for reading the information on the card and converting it into an electrical signal. The code disk structure 20 is installed in the inner cavity 10a of the body 10 and is electrically connected to the control circuit board. The code disk structure 20 is precisely designed to accurately identify the coded information on the card. When the card is inserted into the card slot 10b, part of the code disk structure 20 will extend into the card slot 10b from the first opening, contact the card and start reading the information.

[0047] When the user inserts the card into the card slot 10b, the movement of the card drives the code disk structure 20 to operate. The part of the code disk structure 20 that contacts the card is designed with a precision sensor that can detect the linear speed of the card, that is, the speed at which the card moves in the card slot 10b. This speed information is captured by the code disk structure 20 and converted into an electrical signal, which is then transmitted to the control circuit board through an electrical connection. After receiving the signal, the control circuit board processes the signal according to a preset algorithm and outputs the processed data to an external device, such as a display screen or a computer.

[0048] In an embodiment of the present invention, by adding a code disk structure 20, the plug-in card reader device can significantly reduce the difficulty of software development and software maintenance costs of the device. The introduction of the code disk structure 20 enables the device to directly read the linear velocity information of the card and forward this information to the control circuit board. This design reduces the need for complex algorithms and software logic, because the code disk structure 20 provides a direct and reliable method to obtain the motion state of the card, thereby simplifying the software development process. Developers do not need to write complex code to estimate or simulate the movement of the card, because the code disk structure 20 already provides accurate data input. In addition, due to the physical properties of the code disk structure 20, it reduces maintenance problems caused by software errors or failures, because direct feedback at the hardware level reduces possible problems at the software level. Therefore, the code disk structure 20 not only simplifies software development, but also reduces long-term maintenance costs and improves the stability and reliability of the entire system.

[0049] The design of the main body 10 takes into account durability and user-friendliness. It is made of high-strength plastic or metal to resist wear and impact in daily use. The design of the inner cavity 10a fully considers space utilization and component protection to ensure that all internal components can work in optimal conditions. The design of the card slot 10b takes into account cards of different sizes and shapes to ensure wide compatibility. The design of the first opening ensures that the code disk structure 20 can contact the card smoothly while avoiding unnecessary interference. In addition, the control circuit board also has wireless communication function, which can transmit data to remote devices through wireless technologies such as Bluetooth and Wi-Fi, increasing the flexibility and application range of the device.

[0050] In one embodiment, see Figure 3 and Figure 4 The code disc structure 20 includes a first transmission shaft 21, a code disc 22 and a contact wheel 23. The first transmission shaft 21 is rotatably connected to the inner cavity 10a; the code disc 22 is connected to one end of the first transmission shaft 21; the contact wheel 23 is transmission-connected to the other end of the first transmission shaft 21, and a portion of the contact wheel 23 extends from the first opening into the card insertion slot 10b; wherein, a card inserted into the card insertion slot 10b contacts the contact wheel 23, so that the first transmission shaft 21 drives the code disc 22 to move.

[0051] In an embodiment of the present invention, the first transmission shaft 21 is a key power transmission component in the code disc structure 20, which is responsible for transmitting the power generated when the card is inserted to the code disc 22, thereby starting the data reading process. The first transmission shaft 21 is made of high-strength material to ensure stability and durability during long-term use. The design of the transmission shaft takes into account torque and rotation balance to reduce energy loss and improve transmission efficiency. One end of the transmission shaft is connected to the code disc 22, and the other end is connected to the contact wheel 23, ensuring effective transmission of power.

[0052] The code disk 22 is the core component of the code disk structure 20, which is responsible for converting the information on the card into electrical signals. The code disk 22 is precisely designed, and its surface is covered with special codes that correspond to the information on the card. When the card is inserted into the card slot 10b and contacts the contact wheel 23, the rotation of the contact wheel 23 is transmitted to the code disk 22 through the first transmission shaft 21, causing the code disk 22 to rotate. The sensor on the code disk 22 detects the rotation of the code disk 22 and reads the corresponding card information. The design of the code disk 22 allows it to maintain accurate and stable performance even when rotating at high speeds, which is crucial to ensuring the accuracy of data reading.

[0053] The contact wheel 23 is a part of the code disk structure 20 that directly contacts the card. Its function is to sense the insertion of the card and start the rotation of the code disk 22. The contact wheel 23 is made of wear-resistant material to ensure that the performance is maintained during frequent use. The design of the contact wheel 23 enables it to flexibly adapt to cards of different thicknesses and materials while maintaining a stable contact pressure. A portion of the contact wheel 23 extends from the first opening into the card insertion slot 10b. When the card is inserted, the contact between the contact wheel 23 and the card drives the first transmission shaft 21, thereby driving the code disk 22 to rotate.

[0054] When the user inserts the card into the card slot 10b, the edge of the card first contacts the contact wheel 23. The rotation of the contact wheel 23 is transmitted to the code disk 22 through the first transmission shaft 21, and the code disk 22 starts to rotate. The sensor on the code disk 22 detects the rotation of the code disk 22 and reads the corresponding card information. This information is converted into electrical signals and then transmitted to the control circuit board through electrical connection. After receiving the signals, the control circuit board processes these signals according to the preset algorithm and outputs the processed data to the external device.

[0055] The plug-in card reader device of the present invention realizes efficient and accurate data reading. The introduction of the code disk structure 20 simplifies the software development process because the direct feedback at the hardware level reduces the need for complex algorithms and software logic. Developers do not need to write complex code to estimate or simulate the movement of the card because the code disk structure 20 already provides accurate data input.

[0056] In one embodiment, see Figure 3 and Figure 4 The code disc structure 20 also includes a driving gear 24, a second transmission shaft 25, a driven gear 26 and a transmission belt 27. The driving gear 24 is arranged at the end of the first transmission shaft 21 away from the code disc 22; the second transmission shaft 25 is connected to the contact wheel 23; the driven gear 26 is arranged at the end of the second transmission shaft 25 away from the contact wheel 23; the transmission belt 27 is sleeved on the driving gear 24 and the driven gear 26.

[0057] The driving gear 24 is a power input component in the code disk structure 20, and it is arranged at the end of the first transmission shaft 21 away from the code disk 22. The driving gear 24 receives the power generated by the card insertion through the connection with the first transmission shaft 21. The design of the driving gear 24 takes into account the torque transmission efficiency and durability to ensure stable operation even under high loads. Its tooth shape and material selection are intended to reduce wear and improve transmission efficiency. The second transmission shaft 25 is an intermediate component connecting the contact wheel 23 and the driven gear 26, which transmits the power of the contact wheel 23 to the driven gear 26. The design of the second transmission shaft 25 takes into account the stability and reliability of power transmission, and is made of high-strength material to resist bending and torsion stress. The driven gear 26 is arranged at the end of the second transmission shaft 25 away from the contact wheel 23, and it is connected to the driving gear 24 through a transmission belt 27. The design of the driven gear 26 matches its function, and it receives the power from the driving gear 24 and transmits it to the code disk 22. The precise manufacturing of the driven gear 26 ensures synchronous operation with the driving gear 24, thereby ensuring accurate reading of the code disk 22. The transmission belt 27 is a flexible connecting component sleeved on the driving gear 24 and the driven gear 26, and is responsible for transmitting the power of the driving gear 24 to the driven gear 26. The design of the transmission belt 27 takes into account elasticity and durability to adapt to possible axial and radial deviations. The material and structure of the transmission belt 27 ensure the power transmission efficiency and stability during high-speed operation.

[0058] When a card is inserted into the card slot 10b, the contact wheel 23 first senses the insertion of the card and starts to rotate. This rotation is transmitted to the driven gear 26 through the second transmission shaft 25, and the driven gear 26 then drives the transmission belt 27 to rotate. The transmission belt 27 transmits power to the driving gear 24, and the rotation of the driving gear 24 ultimately drives the code disk 22 to move. In this process, the precise coordination of various components ensures the effective transmission of power and the accurate reading of card information.

[0059] The present invention adds a driving gear 24, a second transmission shaft 25, a driven gear 26 and a transmission belt 27. This design not only improves the response speed and reading accuracy of the device, but also enhances the durability and reliability of the device. The use of the transmission belt 27 reduces the wear that may be caused by direct gear contact, and the design of the multi-stage transmission shaft provides more flexibility and adjustment space to adapt to different card thicknesses and insertion speeds. In general, this technical improvement enables the card reading device to have higher stability and longer service life while maintaining high efficiency.

[0060] In one embodiment, see Figure 3 and Figure 4 The outer peripheral wall of the contact wheel 23 is provided with an elastic rubber layer.

[0061] The contact wheel 23 is a key component in the plug-in card reader that is in direct contact with the card. The outer peripheral wall of the contact wheel 23 is specially designed with an elastic layer. The elastic layer is a layer of elastic rubber material, which is designed to cover the outer peripheral wall of the contact wheel 23. This material is selected based on its excellent elasticity and wear resistance, which can reduce the wear of the card while maintaining good contact. The thickness and hardness of the elastic layer are carefully designed to ensure that consistent contact pressure can be provided under different usage conditions, thereby ensuring the accuracy of data reading.

[0062] The elastic layer added to the outer wall of the contact wheel 23 significantly improves the performance and durability of the plug-in card reader. This design not only improves the smoothness of card insertion and reduces physical damage to the card, but also enhances the adaptability of the device, enabling it to handle various types of cards. The buffering effect of the elastic layer reduces the risk of damage to the device caused by improper card insertion, thereby extending the service life of the device. In addition, the uniform contact pressure of the elastic layer ensures the accuracy and consistency of data reading, improving the overall user experience.

[0063] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The main body 10 is provided with a second opening connected to the card insertion slot 10b, and the second opening is spaced apart from the first opening; the insertion card reader device also includes a rotating shaft and an auxiliary wheel 30, the rotating shaft is rotatably connected to the main body 10, the auxiliary wheel 30 is passed through the rotating shaft, and a part of the auxiliary wheel 30 enters the card insertion slot 10b from the second opening, and the auxiliary wheel 30 is spaced apart from the contact wheel 23.

[0064] In the plug-in card reader device of the present invention, the design of the body 10 is further extended to add a second opening with the card slot 10b. The second opening is a new design feature on the body 10, which is spaced apart from the first opening to provide an additional mechanical channel for the plug-in card reader device. This design allows the device to remain compact while adding more mechanical components to support more complex operations and improve the stability of the device. The shaft is an important mechanical component on the body 10, which is responsible for supporting and driving the rotation of the auxiliary wheel 30. The design of the shaft takes into account strength and durability to ensure stable performance during long-term use. The rotational connection of the shaft allows the auxiliary wheel 30 to flexibly contact the card while reducing friction and wear. The auxiliary wheel 30 is a new component that is inserted into the shaft and is designed to assist the contact wheel 23 to improve the accuracy of card insertion and data reading. Part of the auxiliary wheel 30 enters the card slot 10b from the second opening and is spaced apart from the contact wheel 23, ensuring that the auxiliary wheel 30 can provide additional guidance and support during the card insertion process.

[0065] When a card is inserted into the card slot 10b, the contact wheel 23 first contacts the card and starts to rotate. At the same time, the auxiliary wheel 30 enters the card slot 10b through the second opening and works in conjunction with the contact wheel 23. The auxiliary wheel 30 is designed to maintain good contact with the edge of the card, providing additional guiding force to ensure that the card passes through the card slot 10b smoothly and accurately. The rotating connection of the shaft ensures the flexible movement of the auxiliary wheel 30, reducing equipment damage caused by improper card insertion.

[0066] The present invention adds a second opening, a rotating shaft and an auxiliary wheel 30. This design not only improves the stability and accuracy of card insertion, but also enhances the durability and reliability of the device. The introduction of the auxiliary wheel 30 reduces the friction during the card insertion process, reduces the wear on the card and the device, and also improves the accuracy of data reading. In addition, the guiding effect of the auxiliary wheel 30 makes the card insertion smoother, reduces the risk of the card getting stuck or damaged, and thus improves the user experience.

[0067] In one embodiment, see Figure 1 , Figure 3 and Figure 4 , the auxiliary wheel 30 and the contact wheel 23 are located on the same side of the card insertion slot 10b.

[0068] The auxiliary wheel 30 is a newly added component in the plug-in card reader device. It is installed on the rotating shaft and enters the card slot 10b from the second opening. The auxiliary wheel 30 is designed to provide additional guidance and support to ensure the stability and accuracy of the card during insertion. The contact wheel 23 is a component that directly contacts the card and senses the insertion of the card. Its outer peripheral wall is provided with an elastic rubber layer. This design improves the adaptability and protection of the contact wheel 23 in contact with the card. The contact wheel 23 is connected to the code disk structure 20 through the first transmission shaft 21. When the card is inserted, the rotation of the contact wheel 23 drives the code disk 22 to move, thereby realizing data reading.

[0069] During the card insertion process, the contact wheel 23 first contacts the card and starts to rotate. Due to the elastic rubber layer design of the contact wheel 23, it can adapt to cards of different thicknesses and hardnesses while reducing wear on the card. At the same time, the auxiliary wheel 30 enters the card insertion slot 10b from the second opening and works in conjunction with the contact wheel 23. The design of the auxiliary wheel 30 enables it to provide additional guiding force to ensure that the card passes through the card insertion slot 10b smoothly and accurately. The rotating connection of the shaft ensures the flexible movement of the auxiliary wheel 30 and reduces equipment damage caused by improper card insertion.

[0070] The auxiliary wheel 30 and the contact wheel 23 are located on the same side of the card slot 10b, and this design enables them to work together more effectively. This layout not only improves the stability and accuracy of card insertion, but also enhances the durability and reliability of the device. The guiding effect of the auxiliary wheel 30 reduces the friction during the card insertion process, reduces the wear on the card and the device, and also improves the accuracy of data reading. In addition, the elastic layer of the contact wheel 23 provides better protection, preventing damage to the card during high-speed or irregular insertion.

[0071] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The insertion card reader device further includes two elastic wheels 40 rotatably connected to the body 10 , the two elastic wheels 40 are arranged at intervals on the same side of the card insertion slot 10 b , and the two elastic wheels 40 are arranged one-to-one with the contact wheel 23 and the auxiliary wheel 30 .

[0072] In the insertion card reader device of the present invention, in addition to the contact wheel 23 and the auxiliary wheel 30, two elastic wheels 40 are innovatively introduced that are rotatably connected to the body 10. The two elastic wheels 40 are arranged at intervals on the same side of the card insertion slot 10b, and are arranged one-to-one with the contact wheel 23 and the auxiliary wheel 30, forming a cooperative working system.

[0073] The elastic wheels 40 are two key components on the body 10, which are designed to provide additional elastic support and buffering. Each elastic wheel 40 is made of highly elastic material, which can absorb the impact force when the card is inserted, reducing damage to the card and the device. The rotation of the elastic wheel 40 is connected to the body 10, so that it can flexibly adapt to the card insertion action while maintaining a stable contact pressure.

[0074] The elastic wheels 40 are arranged in a one-to-one correspondence with the contact wheels 23 and the auxiliary wheels 30, which means that each elastic wheel 40 corresponds to one contact wheel 23 and one auxiliary wheel 30. When a card is inserted into the card slot 10b, the contact wheel 23 first senses the insertion of the card and starts to rotate, and the auxiliary wheel 30 follows closely to provide guidance and support. At the same time, the elastic wheels 40 begin to play a role. They absorb the impact force generated when the card is inserted and reduce the direct pressure on the contact wheel 23 and the auxiliary wheel 30, thereby protecting the card from damage and reducing the wear of the device.

[0075] During the card insertion process, the contact wheel 23 and the auxiliary wheel 30 work together to ensure the smooth movement of the card. The contact wheel 23 contacts the card through the elastic layer, starts to rotate and drives the code disk 22 to move, while the auxiliary wheel 30 provides additional guiding force to ensure the accurate insertion of the card. At this time, the intervention of the elastic wheel 40 provides a buffer for the entire system. Their cooperation with the contact wheel 23 and the auxiliary wheel 30 makes the card insertion process smoother and reduces the damage to the card or equipment caused by improper insertion.

[0076] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The body 10 includes a shell 11 and a fixing frame 12, the shell 11 is provided with an inner cavity 10a and an insertion hole 11a connected to the inner cavity 10a; the fixing frame 12 is provided with a card insertion slot 10b and a first opening, and the card insertion slot 10b is arranged corresponding to the insertion hole 11a; the first transmission shaft 21, the contact wheel 23 and the code disk 22 are all arranged on the fixing frame 12, the first transmission shaft 21 and the contact wheel 23 are arranged close to the insertion hole 11a, and the code disk 22 is arranged away from the insertion hole 11a, and is located below the first transmission shaft 21 and the contact wheel 23.

[0077] The shell 11 is the external protective structure of the plug-in card reader device. It is made of a strong and durable material to protect the sensitive components inside from external damage. The shell 11 is designed with an inner cavity 10a, which is a space for accommodating the control circuit board and other key components. The design of the inner cavity 10a fully considers space utilization and component protection to ensure that all internal components can work in the best state. The shell 11 is also provided with an insertion hole 11a connected to the inner cavity 10a. This is the only channel for inserting the card into the device. Its design is convenient for users to operate and can effectively protect the card from being damaged. The fixed frame 12 is a structure used to fix and support the core components of the plug-in card reader device. It is closely matched with the shell 11 to form the basic frame of the device. The fixed frame 12 is provided with a card slot 10b and a first opening. The card slot 10b is the channel for users to insert the card, and the first opening is the part where the code disk structure 20 contacts the card. The design of the fixed frame 12 ensures the corresponding setting of the card slot 10b and the insertion hole 11a, so that the card can be smoothly inserted and trigger the operation of the code disk structure 20. The first transmission shaft 21, the contact wheel 23 and the code disk 22 are all arranged on the fixed frame 12, and their position layout is carefully designed to ensure that the data reading process can be efficiently started when the card is inserted. The first transmission shaft 21 and the contact wheel 23 are arranged close to the insertion hole 11a, so that when the card is inserted, the contact wheel 23 can immediately sense the insertion of the card and start to rotate. The code disk 22 is located below the first transmission shaft 21 and the contact wheel 23, and is arranged away from the insertion hole 11a. Such a layout allows the code disk 22 to rotate stably without being directly interfered by the card, thereby accurately reading the data on the card.

[0078] Through such a well-designed component layout and cooperation process, the combination of the housing 11 and the fixing frame 12 provides a solid and stable operating platform, ensuring that the device can operate stably in various environments. The reasonable layout of the first transmission shaft 21, the contact wheel 23 and the code disk 22 enables the data reading process to be started quickly and accurately when the card is inserted, thereby improving the response speed and reading accuracy of the device. In addition, this design also reduces the complexity of the device, simplifies the assembly and maintenance process, and reduces the production and maintenance costs.

[0079] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The insertion hole 11a is extended along the length direction of the shell 11; the shell 11 is also provided with a groove 11b, which extends along the width direction of the shell 11 and intersects with the insertion hole 11a.

[0080] The insertion hole 11a is an opening extending along the length direction of the housing 11, and it is the main passage for inserting the card into the device. The design of the insertion hole 11a fully considers the convenience of user operation and the protection of the card. Its size and shape precisely match the size of the card, ensuring that the card can be smoothly inserted and withdrawn, while reducing the damage that the card may suffer during the insertion process. The groove 11b is a notch extending along the width direction of the housing 11 and is arranged crosswise with the insertion hole 11a. The design of the groove 11b is intended to provide additional structural stability and serve as a mounting groove for the internal components of the housing 11. The presence of the groove 11b allows the fixing frame 12 and other components inside the housing 11 to be firmly installed in the appropriate position, while also providing additional mechanical strength to the housing 11.

[0081] The cross arrangement of the insertion hole 11a and the groove 11b makes the housing 11 more structurally stable. The insertion hole 11a allows the card to be inserted smoothly, while the groove 11b provides a mounting platform for the fixing frame 12 and other internal components. This design ensures that when the card is inserted, not only the insertion action of the card is guided and supported, but also the internal structure of the device is more stable due to the presence of the groove 11b, reducing the risk of displacement or damage of internal components caused by external impact.

[0082] The precise size and shape of the insertion hole 11a ensure smooth insertion and extraction of the card, reducing the risk of card damage. The setting of the groove 11b not only enhances the structural stability of the housing 11, but also provides a stable installation platform for the internal components, reducing the failure rate of the device. In addition, this design also improves the aesthetics of the device and the user's operating experience, because the cross setting of the insertion hole 11a and the groove 11b makes the appearance of the device more neat and coordinated.

[0083] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The edge of the insertion hole 11a is set in an arc shape.

[0084] The insertion hole 11a is an opening extending along the length of the housing 11, and is used to guide the card into the device. The design of the edge being arranged in an arc shape means that the edge of the insertion hole 11a is not sharp or pointed, but is a smooth arc shape. This design helps to reduce friction when inserting the card, and at the same time avoids possible damage to the card caused by sharp edges.

[0085] The arc-shaped insertion hole 11a makes gentle contact with the card, which is particularly important during the card insertion process. When the card contacts the arc-shaped edge of the insertion hole 11a, the card can smoothly enter the device along the arc track, reducing the resistance during the insertion process. In addition, the arc-shaped edge design also reduces the wear of the card edge due to friction, extending the service life of the card.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
