[0031] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figures 1 to 3 In the first aspect, the present application provides an antenna device for a card holder cavity, comprising: a circuit board component 2, a metal card holder 1 and an IC pin assembly 4; the circuit board component 2 is connected to the metal card holder 1 and combined to form a metal cavity, the IC pin assembly 4 is installed on the circuit board component 2 and arranged in the metal cavity, the IC pin assembly 4 is connected to a radio frequency electrical signal so that the radio frequency electrical signal excites the metal cavity so that the metal cavity forms a cavity antenna, and radiates electromagnetic waves outward through the cavity antenna to complete wireless communication.

[0033] First, let me introduce the functions and roles of each component:

[0034] Circuit board component 2: Circuit board component 2 is specifically a PCB board, which is one of the components of the antenna device. An IC pin assembly 4 is installed on the PCB board, and the PCB board is responsible for circuit connection and signal transmission. The PCB board is connected to the metal card holder 1 to form a metal cavity. An IC card insertion port 3 is provided on the metal cavity. The IC pin assembly 4 is connected to the radio frequency electrical signal to excite the metal cavity through the radio frequency electrical signal, so that the metal cavity forms a cavity antenna, and radiates electromagnetic waves outward through the cavity antenna to realize the transmission of radio frequency electrical signals, thereby improving the efficiency and quality of signal transmission and making wireless communication more stable and reliable.

[0035] Metal card holder 1: The metal card holder 1 is a component of the metal cavity. Its metal material has good conductivity. When combined with the circuit board component 2 to form a metal cavity, it can serve as a radiator of the antenna. Under the excitation of the radio frequency electrical signal, a cavity antenna effect will be generated. The electromagnetic field formed inside the metal cavity can effectively radiate electromagnetic waves outside the IC card insertion port 3 on the metal cavity, thereby realizing wireless communication.

[0036] IC pin assembly 4: allows radio frequency electrical signals to be transmitted to the circuit board component 2 through the IC pin assembly 4, and transmits the radio frequency electrical signals to the metal cavity through the circuit board component 2.

[0037] Therefore, the antenna device can be integrated into the IC card holder through the mutual cooperation of the circuit board component 2, the metal card holder 1 and the IC pin assembly 4, and the antenna effect of the metal cavity is utilized to realize the function of wireless communication, which not only saves space but also improves communication efficiency and is more convenient to use.

[0038] The metal card holder 1 is composed of four metal surfaces.

[0039] In the embodiment of the present application, the metal card base 1 is a component of the antenna device. The metal card base 1 is composed of four interconnected metal surfaces, which together form a semi-enclosed cavity. The metal card base 1 is provided with a bottom surface, two side surfaces and a top cover. The top cover is used to cooperate with the bottom surface and the two side surfaces to form a semi-enclosed cavity.

[0040] Among them, the material of the four metal surfaces on the metal card holder 1 is a metal material with good conductivity and mechanical strength, such as stainless steel, aluminum alloy, etc. These materials are durable enough to resist wear and corrosion in daily use. The metal card holder 1 is connected with the circuit board component 2 to form a metal cavity, which is composed of five surfaces. The metal cavity is provided with an IC card insertion port 3. Under the excitation of the radio frequency electrical signal, the metal cavity will produce a cavity antenna effect, that is, the electromagnetic signal inside the metal cavity will radiate electromagnetic waves outward through the IC card insertion port 3 on the metal cavity, thereby completing the wireless communication function.

[0041] The metal cavity is composed of five surfaces, and an IC card insertion port 3 is arranged on the metal cavity.

[0042] In the embodiment of the present application, the metal cavity is composed of five surfaces, among which one is a circuit board component 2, and the other four are metal surfaces. Specifically, the bottom cover of the metal card holder 1 is in an open state, so the bottom cover of the metal card holder 1 is tightly connected to the circuit board component 2 to form a metal cavity. There is also an opening on the metal cavity, which is the IC card insertion port 3.

[0043] Among them, the IC pin assembly 4 is provided with five required contacts and three optional contacts.

[0044] In the embodiment of the present application, contacts are provided on the IC pin assembly 4, of which there are five required contacts and three optional contacts. The required contacts are an important part of the IC pin assembly 4. A total of eight contacts are provided on the standard IC pin assembly 4, namely: C1: power supply voltage (VCC), C2: reset signal (RST), C3: clock signal (CLK), C4: optional, C5: ground (GND), C6: optional, C7: input / output (I / 0), C8: optional.

[0045] It can be further known that among the eight contacts, C1, C2, C3, C5 and C7 are required contacts, which are used to electrically connect the IC card and the circuit board component 2, while C4, C6 and C8 are optional contacts. The external radio frequency electrical signal can be connected to one of the contacts among C4, C6 or C8 to serve as the contact for feeding excitation.

[0046] Among them, the power contact C1 is used to provide the power required for the IC card to work, and the ground contact C5 is used as a reference point in the circuit to provide a return path for the signal to ensure the normal operation of the circuit. The clock contact C3 provides a clock signal for synchronizing the data transmission between the IC card and the device. The stability and accuracy of the clock signal can determine the correct reading and writing of the data. The data input / output contact C7 is used for bidirectional data transmission. The terminal device sends instructions or data to the IC card through this contact and receives the response or data of the IC card at the same time. The reset / initialization contact C2 is used to reset or initialize the IC card when necessary to ensure that the IC card is in the correct working state.

[0047] By setting five required contacts and three optional contacts on the IC card pin assembly, the IC pin assembly 4 not only meets the basic data transmission and communication requirements, but also can realize feeding excitation for the metal cavity so that the metal cavity can form a cavity antenna.

[0048] The connection between the circuit board component 2 and the metal holder 1 is an integrally formed arrangement.

[0049] In the embodiment of the present application, the connection between the circuit board component 2 and the metal socket 1 is an integrally formed setting, which means that the circuit board component 2 and the metal socket 1 are not connected together by traditional assembly methods, such as screw fixing, glue bonding, etc., but are connected by welding or spot welding to form an indivisible whole, thereby ensuring a seamless connection between the circuit board component 2 and the metal socket 1, eliminating problems such as looseness and displacement caused by improper assembly or long-term use, and the stable structure can improve the durability and reliability of the metal cavity, especially in vibration or impact environments, and can maintain good performance stability.

[0050] The cross-sectional area of ​​the IC card insertion port 3 is larger than the cross-sectional area of ​​the IC card.

[0051] In the present application, the cross-sectional area of ​​the IC card insertion port 3 is set larger than the cross-sectional area of ​​the IC card in order to ensure that the IC card will not be obstructed during the insertion process, thereby improving the convenience of use.

[0052] The IC pin assembly 4 and the circuit board component 2 are integrally formed.

[0053] In the embodiment of the present application, it should be noted that the IC pin assembly 4 and the circuit board component 2 are formed into an inseparable integral structure by welding or spot welding, and the connection is more stable and less likely to loosen.

Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application.
