Description
Technical Field
[0001] The present application relates to the technical field of NFC devices, and in particular to an NFC payment terminal. Background Art
[0002] Currently, NFC-enabled payment terminals generally utilize plastic casings, lacking refinement. This creates a payment experience that doesn't align with current technological expectations and fails to satisfy people's expectations of a technological experience. Related technologies utilize conventional FPC antennas for NFC functionality. These antennas are located inside the terminal's casing. This design limits the payment terminal's spatial communication area, requiring a relatively short distance between the user's phone and the payment terminal for payment to take place.

[0039] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0040] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.
[0041] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.
[0042] See also Figure 1 As shown, an NFC payment terminal 100 provided in an embodiment of the present application can realize the payment function through NFC (near field communication technology) induction with electronic devices such as mobile phones and bracelets. It is particularly suitable for merchants as a cash register device. Consumers can complete electronic payment by placing their electronic devices close to the NFC payment terminal 100, making payment more convenient and improving payment efficiency.
[0043] like Figure 1 and, Figure 2 、 Figure 7 As shown, the NFC payment terminal 100 includes a metal housing 1 and a conductive coil 2. The metal housing 1 includes a second housing 12 with two ends. The two ends of the second housing 12 are respectively provided with a first feeding end 122 and a second feeding end 123. One end of the conductive coil 2 is connected to the first feeding end 122 of the second housing 12, so that the second housing 12 and the conductive coil 2 are connected in series when conducting. When the conductive coil 2 conducts current, the current will pass through the second housing 12. Since the second housing 12 is made of metal, the second housing 12 will generate inductance. In addition, the conductive coil 2 itself will also generate inductance. When the second housing 12 and the conductive coil 2 are connected in series, the sum of the inductance values of the two can meet the NFC performance requirements of the NFC payment terminal 100. That is, in this application, when the second housing 12 and the conductive coil 2 conduct current, they can form an NFC module, forming a spatial communication area at the position of the second housing 12 and its surroundings. When an electronic device approaches the second housing 12 and enters the spatial communication area, the electronic device and the NFC payment terminal 100 perform electronic payment operations.
[0044] When the inductance provided by the NFC module is the same, the distance between the NFC module and the electronic device is L1, and the distance between the electronic device and the NFC payment terminal 100 is L2. If the NFC module is completely located inside the NFC payment terminal 100, then L2 < L1; however, with the solution of the present application, since the second housing 12 itself is part of the NFC module, then L2 = L1.
[0045] So, reference Figure 1 As shown, at least a portion of the second shell 12 is exposed, which can make the distance between the electronic device and the NFC module closer without other obstacles. That is, when the electronic device is farther away from the NFC payment terminal 100, it can enter the spatial communication area, thereby increasing the sensing distance.
[0046] In addition, the housing 1 of the NFC payment terminal of the present application is made of metal, which can provide a sense of technology and achieve the effect of beautifying the appearance. Moreover, the second housing 12 is exposed, which can also reduce the impact of other electronic devices on the NFC function.
[0047] When the NFC payment terminal 100 requires the inductance of the NFC module to be greater than 300uH, the inductance of a circle of the second shell 12 is 110uH in a normal state when it is powered on. The second shell 12 alone cannot meet the inductance required by the NFC payment terminal 100. Therefore, by combining the second shell 12 with the conductive coil 2, the inductance parameters can be improved to meet the inductance requirements.
[0048] In one possible implementation, when the required inductance exceeds the inductance generated by one turn of the second housing 12 and one turn of the conductive coil 2, the inductance can be increased by modifying the number of turns of the conductive coil 2 to meet the inductance requirements of the NFC payment terminal 100. The number of turns of the conductive coil 2 is at least one, and the number of turns of the conductive coil 2 can be set to two, three, four, or more turns depending on the inductance. There is no limit to the number of turns, as long as it meets the inductance requirements of the NFC function.
[0049] A printed circuit antenna (FPC) is a printed circuit antenna made of flexible materials. Combining the advantages of flexible circuit and antenna technologies, it features lightweight, flexible, and bendable features, making it suitable for complex and compact device spaces. FPC antennas offer high performance, low cost, and ease of integration, making them suitable for wireless communications. Therefore, in one possible implementation, conductive coil 2 can be a printed circuit antenna. Of course, wire coil 2 can also be made of iron, for example, and the material type is not limited, as long as the structure satisfies the requirement that wire coil 2 generates inductive flux when energized.
[0050] In a specific embodiment, referring to Figure 8 and Figure 9 The printed circuit antenna includes a printed circuit substrate 21 and a wire 22 with two ends. The printed circuit substrate 21 is fixed to one side of the second shell 12; the wire 22 is provided on the printed circuit substrate 21; the two ends of the wire 22 are respectively a third feeding end 221 and a fourth feeding end 222, and the third feeding end 221 is connected to the first feeding end 122 of the second shell 12, so that the second shell 12 and the wire 22 are connected in series, thereby realizing series conduction between the wire 22 and the second shell 12.
[0051] It should be noted that the printed circuit substrate 21 is non-conductive and can be fixed to one side of the second shell 12 by, but not limited to, gluing or fasteners, as long as the printed circuit substrate 21 can be fixed to one side of the second shell 12.
[0052] In one possible implementation, the NFC payment terminal 100 further includes a chip module, and the second feeding end 123 of the second housing 12 and the fourth feeding end 222 of the wire 22 are electrically connected to two different terminals on the chip module, respectively, so that a series path can be formed.
[0053] In one possible implementation, refer to Figure 5 The second feeding terminal 123 and the fourth feeding terminal 222 are each connected to a conductive sheet 5. Specifically, a conductive sheet 5 is provided between the second feeding terminal 123 and the chip module, and a conductive sheet 5 is provided between the fourth feeding terminal 222 and the chip module. The conductive sheet 5 serves as an electrical connection. The fourth feeding terminal 222 of the wire 22 is electrically connected to the chip module through the conductive sheet 5, and the second feeding terminal 123 of the second housing 12 is electrically connected to the chip module through the conductive sheet 5.
[0054] In one possible implementation, refer to Figures 2 to 4 The first feeding end 122 of the second shell 12 and the third feeding end 221 of the conductive coil 2 are fixedly connected by the first fastener 3 to achieve a stable connection between the second shell 12 and the conductive coil 2.
[0055] In a possible implementation, the second feeding end 123 of the second housing 12 and the conductive sheet 5 may be fixedly connected via a second fastener 7 to achieve a stable connection between the second housing 12 and the conductive sheet 5 .
[0056] Specifically, the first fastener 3 and the second fastener 7 can be screws or the like. The present application does not limit the specific types of the first fastener 3 and the second fastener 7 as long as they can ensure a stable connection.
[0057] In one possible implementation, in order to avoid the situation where the first fastener 3 damages the conductive coil 2 when the second shell 12 is fastened to the conductive coil 2, a conductive gasket 4 may be provided at the connection between the first feeding end 122 of the second shell 12 and the third feeding end 221 of the conductive coil 2 corresponding to the first fastener 3 to protect the conductive coil 2.
[0058] In one possible implementation, in order to avoid the second fastener 7 from damaging the conductive sheet 5 during tightening, a conductive gasket 4 is also provided at the connection between the second feeding end 123 of the second shell 12 and the conductive sheet 5 corresponding to the second fastener 7 to protect the conductive sheet 5.
[0059] In one possible implementation, the metal housing 1 further includes a first housing 11, which is connected to a second housing 12 via an insulating member (not shown). It is understood that the insulating member connecting the first housing 11 and the second housing 12 prevents electrical conduction between the first housing 11 and the second housing 12. When power is applied to the second housing 12, the insulating member prevents current from being conducted to the first housing 11, thereby affecting the NFC performance of the NFC payment terminal 100.
[0060] refer to Figure 3 and Figure 4 The gap 1a between the first housing 11 and the second housing 12 is filled with an insulating member to isolate the first housing 11 and the second housing 12 from electrical conduction. In one possible implementation, the insulating member is made of plastic, and the plastic is used to separate the first housing 11 and the second housing 12, thereby realizing the NFC function.
[0061] In one possible implementation, refer to Figure 1 As shown, the second housing 12 and the first housing 11 are substantially located on the same plane, which facilitates payment operations.
[0062] In one possible implementation, refer to Figure 2 A first positioning block 121 is provided on the circumference of the second housing 12 facing the conductive coil 2. Figure 4 and Figure 6 The first shell 11 is provided with an arc-shaped second positioning block 111, and the second shell 12 is partially accommodated in the arc-shaped groove of the second positioning block 111; the first positioning block 121 is also arc-shaped, and the first positioning block 121 and the second positioning block 111 enclose a circular installation cavity 1b, and the conductive coil 2 is located in the installation cavity 1b, which can achieve an aesthetic effect of the NFC payment terminal and play a positioning role in the production and assembly process of the NFC payment terminal, thereby improving assembly efficiency. It should be noted that this application does not impose any restrictions on the shape and structure of the first positioning block 121 and the second positioning block 111, as long as the first positioning block 121 and the second positioning block 111 enclose a mounting cavity.
[0063] In one possible implementation, refer to Figure 1 As shown, the first housing 11 is provided with a display screen 6 for displaying information to be paid, etc., to guide consumers to complete electronic payment.
[0064] In one possible implementation, refer to Figure 1 As shown, the display screen 6 is located on the front side of the NFC payment terminal 100 , that is, facing the consumer, so that the consumer can see the information displayed on the display screen 6 and improve the payment experience.
