[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] In related technologies, antennas are typically mounted on the housing or other structures of electronic devices. Taking financial applications as an example, for payment terminals such as financial POS terminals, the NFC antenna is a key component for NFC payments. However, NFC antennas in these technologies require assembly using a two-wound antenna, which involves four solder points. Even with two turns of winding, the antenna is prone to detachment. Furthermore, the placement of the antenna during mounting is difficult to control, leading to assembly challenges and high costs.

[0019] To address the aforementioned technical problems, this utility model provides an antenna structure, device, and electronic device, as detailed below: An antenna structure includes a fixed film; the fixed film is a ring-like structure, the ring-like structure including an inner ring and an outer ring; an antenna is disposed on the outer ring; the inner ring is used to attach to the outer surface of an external structure.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: a ring-shaped fixing film is used to set the antenna, so that the antenna structure forms a ring structure, and the inner side of the fixing film is attached to the outer surface of the outer structure, so that the antenna structure can be directly fitted onto the outer structure, thereby eliminating the matching operation between the antenna and the outer structure, eliminating the need for pasting and wrapping along the preset area, and the single ring structure only requires two solder points, thereby solving the difficulty of antenna assembly and reducing costs.

[0021] In an optional embodiment, a fixing part is provided on the fixing membrane; the fixing part is used for positioning and connection with an external structure.

[0022] As described above, by setting a fixing part on the fixing film, when the antenna structure is fitted onto the external structure, it can be positioned and connected to the external structure through the positioning part, which plays a role in positioning and fixing the antenna structure and improving the stability of the antenna structure.

[0023] In an optional embodiment, the fixing film includes at least two fixing portions, and the fixing portions are arranged in different directions of the fixing film.

[0024] As described above, by setting multiple sets of fixing parts on the fixing film and placing the fixing parts in different directions, the multiple sets of fixing parts in different directions can play a positioning and fixing role on the fixing film in different directions, thereby improving the stability of the antenna structure.

[0025] The fixing parts include at least two different types. By setting different types of fixing parts, that is, by using different methods to directly form positioning connections with the external structure, the positioning connection effect is achieved through the joint cooperation of multiple sets of different types of fixing parts, thereby further improving the stability of the antenna structure.

[0026] In one optional embodiment, the fixing part includes a positioning hole. Using a positioning hole as a positioning connection method for the fixing part allows it to cooperate with structures such as positioning posts on an external structure to achieve a positioning connection with the fixing membrane.

[0027] In another alternative embodiment, the fixing part includes a positioning groove. Using a positioning groove as a positioning connection method for the fixing part allows it to cooperate with structures such as protrusions on the external structure to achieve a positioning connection with the fixing membrane.

[0028] In another alternative embodiment, the fixing part includes a positioning hole and a positioning groove.

[0029] In an alternative embodiment, the fixing film comprises a PET film.

[0030] As described above, using PET film as a fixing film can support the antenna and avoid the inability to shape the antenna due to its soft overall structure, which would make it difficult to attach to the external structure.

[0031] In an alternative embodiment, the antenna is wound around the outside of the loop, and the first and last segments of the antenna are intertwined.

[0032] As described above, twisting the first and last sections of the antenna together can increase the antenna's inductance.

[0033] Another embodiment of the present invention provides an antenna device, including a main board, a housing, and the antenna structure described above; the antenna structure is sleeved on the outer surface of the housing and fits against the outer surface of the housing; the main board is disposed on the housing and is electrically connected to the antenna structure.

[0034] As described above, in the antenna device, the antenna structure can be directly fitted onto the external structure without the need for pasting or wrapping along a preset area. Furthermore, the single-loop structure only requires two solder points to connect to the motherboard, thereby solving the difficulty of antenna assembly and reducing costs.

[0035] In one optional embodiment, the housing is provided with a positioning post and a locking block; the positioning post is connected to the positioning hole of the antenna structure; and the locking block is engaged with the positioning groove of the antenna structure.

[0036] As described above, by setting positioning posts and locking blocks on the housing, the antenna structure can be effectively positioned in the housing by the positioning posts engaging with the positioning holes on the antenna structure and the locking blocks engaging with the positioning slots on the antenna structure.

[0037] In one optional embodiment, the housing is provided with a wiring section; the width of the wiring section is adapted to the width of the antenna; the antenna structure is disposed within the wiring section.

[0038] As described above, by providing a wiring section on the housing, and ensuring that the width of the wiring section matches the width of the antenna, the antenna structure is placed inside the wiring section, which then guides and limits the antenna structure.

[0039] Another embodiment of this utility model provides an electronic device including the aforementioned antenna device. The electronic device can be a financial POS device; the antenna device serves as a functional module within the POS device. For example, in the antenna device, the housing can be the printer housing, and the antenna structure is fitted onto the outer wall of the printer housing. The printer housing structure is fully utilized, with positioning posts, locking blocks, and wiring sections all positioned on the outer wall of the printer housing for engagement with positioning holes and slots on the antenna structure.

[0040] The antenna structure, device, and electronic equipment provided by this utility model can be applied to smart devices, such as POS machines and handheld printers. The following detailed embodiments illustrate these applications: Example 1 Please refer to Figure 1 An antenna structure 100 includes a fixing film 110. The fixing film 110 is a ring-like structure, including an inner ring and an outer ring. An antenna 120 is disposed on the outer ring. For example, the antenna 120 is a coil of copper wire, which is pressed onto the fixing film 110 when the antenna 120 is installed. The inner ring is used to attach to the outer surface of an external structure. The fixing film 110 can be made of materials such as PET (Polyethylene terephthalate) to provide some support for the copper wire structure. Some antennas 120 are flexible structures; if the fixing film 110 does not provide support, the antenna 120 will be difficult to attach to the external structure. The ring-like structure can be designed according to the shape of the external structure to be fitted, so that the ring-like structure fits the external structure perfectly; for example, if the external structure is a quadrangular prism, the ring-like structure is set as a ring structure with four sides, and the two ends of the ring structure are not closed, serving as feed points for wires to be led out for connection with the circuit on the motherboard 200. Please refer to... Figure 6 In an alternative embodiment, the antenna 120 is wound around the outside of the ring, and the first and last segments of the antenna 120 are intertwined.

[0041] In an optional embodiment, a fixing part 130 is provided on the fixing film 110; the fixing part 130 is used for positioning and connecting with an external structure; by providing the fixing part 130, it can cooperate with the structure on the external device, thereby improving the stability of the antenna structure 100.

[0042] The fixing membrane 110 includes multiple sets of fixing portions 130, which are disposed in different directions. For example, when the ring-like structure has four sides, the fixing portions 130 can be disposed in the length direction and the width direction respectively. Furthermore, the fixing portions 130 include multiple different types. For example, in this embodiment, the fixing portions 130 include two types: positioning holes 131 and positioning grooves 132. Figure 1 As shown, positioning holes 131 are provided on both the left and right sides of the antenna structure 100. The number of positioning holes 131 can be set according to the length of the fixing film 110. If the length is long, multiple positioning holes 131 can be provided on the same side. Figure 1 Two positioning holes 131 are provided on the right side. Two positioning slots 132 are provided on the upper side of the antenna structure 100, which are realized by bending the antenna structure 100.

[0043] The antenna structure 100 described above is assembled with an external structure to form an antenna device. For example, in this embodiment, the antenna structure 100 is applied to a handheld printer scenario. The antenna device is formed by fitting the antenna structure 100 onto the paper tray structure of the handheld printer. The specific structure of the antenna device is as follows: Please refer to Figure 3 An antenna device includes a main board 200, a housing 300, and the aforementioned antenna structure 100. The antenna structure 100 is sleeved on the outer surface of the housing 300 and is attached to the outer surface of the housing 300. The main board 200 is disposed on the housing 300 and electrically connected to the antenna structure 100. For example, the wires led out from the antenna structure 100 are soldered to the circuit of the main board 200, or a connection terminal is provided on the main board 200 and the wires are plugged into the terminal.

[0044] Please refer to Figures 3 to 5 The housing 300 is provided with a positioning post 310 and a locking block 320; the positioning post 310 is connected to the positioning hole 131 of the antenna structure 100; the locking block 320 is engaged with the positioning groove 132 of the antenna structure 100. The housing 300 is provided with a wiring section 330; the width of the wiring section 330 is adapted to the width of the antenna 120; the antenna structure 100 is disposed within the wiring section 330; that is, the bottom of the wiring section 330 supports the antenna structure 100, and the top of the wiring section 330 limits the antenna structure 100, thus limiting the antenna structure 100 between the bottom and top of the wiring section 330. Figure 3 as well as Figure 5As shown, in order to cooperate with the wiring portion 330 on the housing 300, the antenna structure 100 is also provided with a folded section 140. By forming the folded section 140 at a specific position on the antenna structure 100, a close fit with the structure of the housing 300 is achieved. By having the positioning post 310, the locking block 320 and the wiring portion 330 on the housing 300 cooperate with the positioning hole 131, the positioning groove 132 and the folded section 140 on the antenna structure 100 respectively, it is easier to position and route the antenna structure 100, and to stably mount the antenna structure 100 on the housing 300.

[0045] The aforementioned antenna device is applied to smart devices and used as an electronic device. For example, the electronic device is a financial POS device; the antenna device serves as a functional module within the POS device. For instance, the housing 300 in the antenna device is the paper tray of a printer, and the antenna structure 100 is fitted onto the outer wall of the paper tray. Taking full advantage of the paper tray structure, the positioning post 310, the locking block 320, and the wiring section 330 are all located on the outer wall of the paper tray, for cooperation with the positioning holes 131 and positioning slots 132 on the antenna structure 100, enabling the POS device to have printing functionality and communication functionality via the antenna 120.
