Description

Technical Field

[0001] The utility model relates to the technical field of card readers, in particular to a portable contactless smart card reading and writing device. Background Art

[0002] The contactless smart card reader is a key device, which is widely used in hotels, Internet cafes, entrances and exits, etc. It is mainly used for identity authentication and access control. Its structure includes an antenna, a radio frequency module, a control unit, a housing and a connection interface. It is based on radio frequency identification technology. The working principle is to send a radio frequency signal through the reader, and the smart card responds and transmits data. The reader transmits the data to the external system for verification and control. Its functions include identity authentication, access control, data recording and improving convenience; such as a portable contactless smart card reader disclosed in the authorization announcement number CN216361958U, including a body, a contactless card reader slot, a contact card reader slot, and a liquid crystal code-changing keyboard are arranged on the periphery of the body, and the liquid crystal code-changing keyboard is a curved screen, and the surface is covered with A flexible privacy film is provided, and a shading frame is arranged around the liquid crystal keyboard. Diffusion lights are installed on both sides and the top outer wall of the shading frame, and a shading cover extending outward is provided on the top of the shading frame. The shading cover automatically and randomly changes the position of the numbers on the keyboard when inputting, and the privacy film prevents the people beside the user from inferring the password by key gestures. However, the body in this technical solution is a plate-like structure, which needs to be placed flat or placed on the front desk counter with the help of a bracket. Such a design causes the reader to occupy a certain amount of counter space during use. For some places with limited space, such as cash registers, hotel front desks, etc., this space occupation will cause inconvenience or affect the progress of other operations. Moreover, since the contactless smart card reader needs to be placed on the counter, there is also a risk of accidental collision or falling. Utility Model Content

DETAILED DESCRIPTION

[0020] The elastic member 3 is a coil spring, the top of which is fixedly connected to the bottom of the upper clamping plate 2. When the elastic member 3 is a spring, when the upper clamping plate 2 and the hollow bottom shell 1 are stretched apart due to external force, the spring is in a compressed state, and the reverse force generated by the spring enables the hollow bottom shell 1 and the upper clamping plate 2 to stably clamp the table top.

[0021] The connecting foot 6 and the U-shaped housing 7 are both made of hard plastic material, which has good wear resistance and corrosion resistance, can effectively resist the influence of the external environment, and ensure the long-term stability and reliability of the connecting foot 6 and the U-shaped housing 7;

[0022] The connecting foot 6 serves to connect and fix the U-shaped housing 7 and the horizontal shaft 5, so that the horizontal shaft 5 can drive the U-shaped housing 7 to move when rotating;

[0023] A ball head connector 8 is provided on the inner wall of one side of the U-shaped shell 7, and the movable end of the ball head connector 8 is fixedly connected to the back of the contactless IC card reader 9. The ball head connector 8 includes a ball seat 801 fixed on the inner wall of one side of the U-shaped shell 7, and a plastic inner ball head 802 installed on the back of the contactless IC card reader 9. The plastic inner ball head 802 and the ball seat 801 are mutually embedded. When using the contactless IC card reader 9, the user can swing the contactless IC card reader 9 so that the contactless IC card reader 9 drives the plastic inner ball head 802 to rotate and adjust with the ball seat 801 as the center, that is, fine-tune the angle of the contactless IC card reader 9;

[0024] The rotation drive assembly 11 includes a stepper motor 1101 installed on one side of the interior of the hollow bottom shell 1, and a main shaft 1102 installed at the output end of the stepper motor 1101. One end of the transverse axis 5 extends to the interior of the hollow bottom shell 1 and is installed with a bevel gear right-angle transmission structure 1104. One end of the main shaft 1102 is installed with a worm gear transmission structure 1103 for driving the bevel gear right-angle transmission structure 1104 to rotate. The bevel gear right-angle transmission structure 1104 includes a driven shaft rotatably installed on one side of the interior of the hollow bottom shell 1, and bevel gears installed at opposite ends of the driven shaft and the transverse axis 5, and the two bevel gears are meshed with each other. The worm gear transmission structure 1103 includes a worm installed at the top of the main shaft 1102, and a worm wheel disk fixed to one end of the surface of the driven shaft, and the worm wheel disk and the worm are meshed with each other.

[0025] When the stepper motor 1101 drives the main shaft 1102 to rotate, the rotational power of the main shaft 1102 is transmitted to the bevel gear right-angle transmission structure 1104 through the worm gear transmission structure 1103, and the bevel gear right-angle transmission structure 1104 drives the horizontal axis 5 to rotate. During this process, the worm gear transmission structure 1103 has a self-locking property, which can maintain the rotation angle of the horizontal axis 5 to ensure that the contactless IC card reader 9 is in a stable upright state.

[0026] When the embodiment of the present application is in use, the staff first takes out the device and clamps the hollow bottom shell 1 and the upper clamping plate 2 on the edge of the front desk near the staff. At this time, the elastic member 3 is deformed and compressed because the hollow bottom shell 1 and the upper clamping plate 2 are stretched open by the edge of the front desk board, so that the hollow bottom shell 1 and the upper clamping plate 2 are firmly clamped on the edge of the front desk board. The user can communicate with the contactless IC card reader 9 through the radio frequency module inside the contactless IC card reader 9. When the external device connected to the contactless IC card reader 9 receives the data transmitted by the contactless IC card reader 9, it will verify the information in the smart card to confirm the identity or authority of the user. According to the verification result, the corresponding device will decide whether to authorize the user to perform the corresponding operation, such as opening the door, logging in, etc. By installing the reader on the side edge of the front desk table, The space on the desktop is effectively utilized, making the entire working area more spacious and tidy. When the staff no longer needs to use the contactless IC card reader 9, the staff can send a working signal to the circuit board 10 through the button 4, and the circuit board 10 controls the rotation drive component 11 to work according to the set direction, speed, angle, and response time, and then the rotation drive component 11 is actuated, and the horizontal axis 5 is rotated 180 degrees counterclockwise. At this time, the U-shaped shell 7, the contactless IC card reader 9 and other components are rotated to the bottom of the front desk edge, so as to achieve the purpose of hiding the contactless IC card reader 9, so that the reader can be automatically hidden under the table when not in use, which will not affect the normal work process, and can also reduce the risk of the reader being accidentally hit or falling, thereby reducing the possibility of damage.
