A contactless antenna, antenna structure, and electronic device

Abstract

This utility model discloses a contactless antenna, antenna structure, and electronic device, including a substrate and an antenna. The substrate has a ring-like structure with corner breaks at the corners. The substrate includes a first surface and a second surface. The first surface is used to adhere to an external structure. The antenna is continuously arranged around the second surface and passes through the corner breaks in sequence. By setting the substrate to a ring-like structure and arranging the antenna around the second surface of the substrate, the contactless antenna can be fitted onto the device. Simultaneously, because the ring-like structure has corner breaks, the substrate can adhere to the mounting surface of the device, avoiding curling edges and thus ensuring the contactless antenna is stably fixed to the device.

[0016] 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.

[0017] In related technologies, contactless antennas are typically fabricated using FPC (Flexible Printed Circuit) or PCB (Printed Circuit Board), and then the FPC or PCB with the contactless antenna is glued to the surface of the device. However, this method is costly. On the other hand, the relatively low-cost enameled wire needs to be wound around the housing, which cannot meet the needs of rapid installation and cannot be stably fixed to the device.

[0018] To solve the above-mentioned technical problems, this utility model provides a contactless antenna, antenna structure, and electronic device, which makes the installation of contactless antennas more stable.

[0019] A non-contact antenna includes a substrate and an antenna; the substrate has a ring-like structure, and the corner of the ring-like structure has a corner break area; the substrate includes a first surface and a second surface, the first surface being used to fit with an external structure; the antenna is continuously arranged around the second surface and passes through the corner break area in sequence.

[0020] As described above, the beneficial effects of this utility model are as follows: by setting the substrate to a ring-like structure, the substrate includes a first surface and a second surface. The first surface is used to fit with an external structure, and the antenna is arranged around the second surface of the substrate and passes through the break area in sequence. Therefore, through the solution of this application, the non-contact antenna can be attached to the external device through the first surface. At the same time, since the break area is set at the corner of the ring-like structure, the substrate can fit with the mounting surface of the device, and the curling problem caused by the continuous arrangement of the substrate can be avoided, so that the non-contact antenna can be stably fixed on the device.

[0021] In an optional embodiment, the substrate is provided with positioning holes for connection with an external structure.

[0022] As described above, by providing positioning holes on the substrate, the contactless antenna can be positioned and fixed when it needs to be placed on the device, thereby improving the stability of the contactless antenna.

[0023] In an alternative embodiment, the first surface is provided with an adhesive.

[0024] As described above, by providing an adhesive, such as glue, on the first surface of the substrate, the substrate can be tightly attached to the device, thereby achieving the fixation of the non-contact antenna.

[0025] In an optional embodiment, at least one side of the ring-like structure is provided with an in-side break region.

[0026] As described above, by setting an inner break area on the side of the ring-like structure, the non-contact antenna can avoid uneven parts such as protrusions on the device, thus allowing the non-contact antenna to fit snugly against the device.

[0027] In an alternative embodiment, the antenna comprises enameled wire or copper wire; the enameled wire or copper wire is disposed around the second surface.

[0028] As can be seen from the above description, using enameled wire as the antenna and surrounding it on the second surface can avoid the problem of short circuits caused by contact between coils.

[0029] Another embodiment of the present invention provides an antenna structure, including a housing and a non-contact antenna as described above; the non-contact antenna is sleeved on the housing; the first surface of the substrate of the non-contact antenna is attached to the housing.

[0030] As can be seen from the above description, by mounting the contactless antenna on the housing, the assembly efficiency of the contactless antenna is improved compared to the traditional method of wrapping and attaching the contactless antenna along the housing.

[0031] In an optional embodiment, the housing is provided with an annular mounting area; the corner break area at the corner position on the substrate corresponds to the corner position of the annular mounting area.

[0032] As described above, by aligning the corner breakage area on the substrate with the bend position of the annular mounting area, i.e., after the substrate with a ring-like structure is broken at the bend position of the annular mounting area, it continues to be set along the annular mounting area, thus avoiding the situation of the substrate curling at the corner position, so that the entire non-contact antenna can be attached to the annular mounting area.

[0033] In an optional embodiment, a structural member is provided on the annular mounting area; the side-opening region on the substrate corresponds to the structural member of the annular mounting area.

[0034] As described above, by aligning the inner edge break area on the side of the substrate with the structural component of the annular mounting area, i.e., after the substrate with a ring-like structure is broken at the position of the structural component in the annular mounting area, it continues to be set along the annular mounting area, thus avoiding interference between the substrate and the structural component on the shell, which would cause problems such as curling and failure to adhere.

[0035] In an optional embodiment, a positioning post is provided on the annular mounting area; the positioning hole on the substrate is connected to the positioning post.

[0036] As described above, by setting positioning posts on the annular mounting area and through the cooperation between the positioning posts and positioning holes, the non-contact antenna can be effectively fixed on the housing.

[0037] Another embodiment of this utility model provides an electronic device, including a contactless antenna as described above. The electronic device can be a financial POS device; the antenna structure is a functional module within the POS device. For example, in the antenna structure, the housing can be the printer housing, and the contactless antenna is fitted onto the outer wall of the printer housing.

[0038] The contactless antenna, antenna structure, and electronic device 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 as well as Figure 2 A non-contact antenna 100 includes a substrate 110 and an antenna 120. The substrate 110 has a ring-like structure with corner break areas 111 at the corners, essentially forming a ring-like structure from multiple line segments. The substrate 110 includes opposing first and second surfaces. The first surface is used to attach to an external structure. The antenna 120 is continuously arranged around the second surface and passes through the corner break areas 111. The substrate 110 can be made of materials such as PET (Polyethylene terephthalate). The ring-like structure can be configured according to the external structure to be assembled. For example, if the mounting area of ​​the external structure is rectangular, the ring-like structure is a ring structure with four sides to fit the rectangular external structure; if the external structure is polygonal, the ring-like structure is a ring structure with the same number of corresponding sides. Antenna 120 includes enameled wire or copper wire; the enameled wire or copper wire is wrapped around the second surface, and the number of turns can be set according to the actual situation; antenna 120 is disposed on the first surface of substrate 110 by pressing.

[0039] like Figure 1 As shown, the substrate 110 is also provided with positioning holes 130, which are used for connection with external structures. The number and distribution of positioning holes 130 on the substrate 110 can be set according to the shape of the external structure to be assembled, so as to achieve overall positioning of the non-contact antenna 100. To improve the connection strength between the non-contact antenna 100 and the external structure, an adhesive 140 is provided on the first surface of the substrate 110. For example, glue is used as the adhesive 140. The glue is applied to the first surface of the substrate 110 as the backing surface for bonding with the surface of the external structure.

[0040] In this ring-like structure, at least one side has an inner break region 112. For example, if the non-contact antenna 100 needs to be mounted on a rectangular outer structure, the substrate 110 forms a rectangular structure, creating four side positions. The substrate 110 has four corner break regions 111 at the four corner positions, effectively forming a rectangular structure with four line segments. Simultaneously, since the surface of the outer structure may have uneven structural components 212 such as protrusions or depressions, by providing corner break regions 111 at corresponding positions on the substrate 110, these uneven areas can be avoided, allowing the substrate 110 to cover the surface of the outer structure. Figure 1 as well as Figure 2As shown, an inner break area 112 is provided on each of the upper and lower side positions, which is equivalent to a side being composed of two sub-segments; at the same time, the two sub-segments can be set in the same direction or in different directions, that is, the sub-segments can be adjusted in the inner break area 112; for example, the two sub-segments are set on the same side wall of the external structure, and one sub-segment forms an angle with the other sub-segment.

[0041] Please refer to Figure 3 An antenna structure includes a housing 200 and a contactless antenna 100 as described above. The contactless antenna 100 is sleeved on the housing 200. The first surface of the substrate 110 of the contactless antenna 100 is attached to the housing 200. An annular mounting area 210 is provided on the housing 200. The contactless antenna 100 is attached to the annular mounting area 210, and the corner break area 111 at the corner position on the substrate 110 corresponds to the bend position 211 of the annular mounting area 210. In an optional embodiment, limiting blocks 230 are respectively provided on the upper and lower sides of the annular mounting area 210, which can limit the contactless antenna 100 within the annular mounting area 210 defined by the limiting blocks 230 on the upper and lower sides.

[0042] A structural member 212 is provided on the annular mounting area 210; wherein, the structural member 212 includes protrusions, depressions, etc., forming an uneven structure on the annular mounting area 210. The inner edge break area 111 on the side of the substrate 110 corresponds to the structural member 212 of the annular mounting area 210. Figure 3 As shown, structural component 212 is a protrusion; by setting an inner break area 111 at a corresponding position on the substrate 110, the protrusion position can be avoided. A positioning post 220 is provided on the annular mounting area 210; the positioning hole 130 on the substrate 110 is connected to the positioning post 220.

[0043] An electronic device includes the aforementioned contactless antenna 100. The electronic device may be a financial POS device; the antenna structure serves as a functional module within the POS device. For example, in the antenna structure, the housing 200 may be the printer compartment, and the contactless antenna 100 is mounted on the outer wall of the printer compartment.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
