Detailed Implementation

[0037] The embodiments of this disclosure are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of this disclosure are described in detail below.

[0038] Typically, NFC entry modules are installed in rearview mirrors. However, the limited space within the mirror, due to its shape and the need to accommodate other functional modules, results in a small usable area. Furthermore, the placement of the NFC entry module is critical; the closer the NFC antenna board is to the card reader, the better the card-reading performance. The curved inner wall of the rearview mirror also limits the size of the NFC antenna board, thus restricting the overall antenna area and hindering the design of a conveniently placed, high-performance NFC entry module.

[0039] In related technologies, the in-vehicle NFC access module uses upper and lower plastic housings to assemble a printed circuit board antenna board and a printed circuit board main board. The printed circuit board main board connects to the vehicle via a waterproof connector wiring harness for power supply and communication. However, the rigid connection between the printed circuit board antenna board and the printed circuit board main board necessitates leaving a certain distance between them or adding shielding materials to eliminate interference, thus complicating the design of the in-vehicle NFC access module.

[0040] The following description, with reference to the accompanying drawings, describes an NFC access module 100 according to some embodiments of the present disclosure, which is applied in a vehicle, such as a rearview mirror 200.

[0041] As shown in Figures 1 and 2, the NFC access module 100 according to the first aspect of the present disclosure includes a housing 110, a motherboard 120 and an antenna board 130. The motherboard 120 is disposed inside the housing 110, the antenna board 130 is electrically connected to the motherboard 120, and the antenna board 130 is disposed outside the housing 110.

[0042] Understandably, the housing 110, motherboard 120, and antenna board 130 constitute the main structure of the NFC access module 100. The motherboard 120 is located inside the housing 110, thus protecting it and extending its lifespan. The antenna board 130 is located outside the housing 110 and is electrically connected to the motherboard 120, allowing it to avoid occupying space within the housing 110 and saving space in the NFC access module 100. Furthermore, the antenna board 130 can fit against the curved inner wall of the rearview mirror 200, increasing its flexibility and improving the performance of the NFC access module 100. For example, the antenna board 130 can be a flexible printed circuit (FPC) circuit board. The flexible circuit board can be attached to the curved inner wall of the rearview mirror 200, thereby increasing the usable area of ​​the antenna board 130. Moreover, the flexible circuit board is equipped with a transmitting coil and a receiving coil, which can improve the signal reception and transmission function of the antenna board 130, thereby improving the performance of the NFC entry module 100.

[0043] Therefore, by placing the motherboard 120 inside the housing 110 and the antenna board 130 outside the housing 110, and electrically connecting the antenna board 130 and the motherboard 120, the antenna board 130 does not occupy space in the housing 110, thus saving space for the NFC access module 100. The antenna board 130 can be placed close to the inner wall of the rearview mirror 200, thereby improving the performance of the NFC access module 100 and making it easier for users to use the NFC function.

[0044] Additionally, as shown in Figures 1 and 2, the NFC access module 100 also includes a wiring harness 140. The housing 110 has a wiring hole through which the wiring harness 140 passes, connecting the motherboard 120 and the antenna board 130. In other words, the wiring hole on one side of the housing 110 allows the wiring harness 140 to be positioned, thus optimizing the layout space of the NFC access module 100. Furthermore, the wiring harness 140 connects the motherboard 120 and the antenna board 130, enabling them to be connected and providing a more stable electrical connection, thus facilitating the use of NFC functionality. For example, the wiring harness 140 connects the motherboard 120 and the central controller, allowing the user to control the motherboard 120 via the central controller, or for the motherboard 120 to transmit signals to the central controller.

[0045] Furthermore, in some embodiments, the housing 110 includes a sealing ring disposed in a wiring hole, through which the wiring harness 140 passes. It is understood that the sealing ring is disposed on the inner circumference of the wiring hole, and the wiring harness 140 passes through the sealing ring before connecting to the motherboard 120 and the antenna board 130. This prevents liquid from entering the housing 110 through the wiring hole, thereby extending the lifespan of the motherboard 120 and ensuring the performance of the NFC access module 100.

[0046] Additionally, as shown in Figure 3, the antenna plate 130 is provided with at least one first fixing part 131, which is configured to connect with a structural component of the vehicle. For example, the at least one first fixing part 131 may include multiple first fixing parts 131, which are respectively located at the end corners of the antenna plate 130. That is, the multiple first fixing parts 131 are located at the end corners of the antenna plate 130, thereby making the connection between the antenna plate 130 and the structural component more secure, thus facilitating the user's use of the NFC function. For example, the first fixing part 131 may be fixed to the structural component by means of adhesive backing, hot melt, dispensing, or screw connection, thereby facilitating the fixing of the antenna plate 130 to the structural component. The structural component may be the inner wall, outer wall, center of the housing, or inner wall of the door of the rearview mirror 200, thereby making the connection between the antenna plate 130 and the structural component more secure.

[0047] Furthermore, as shown in Figures 1 and 2, the outer casing 110 includes a housing 111 and a cover 112. The main board 120 is disposed within the housing 111, and the cover 112 is disposed within the housing 111. It can be understood that the housing 111 and the cover 112 constitute the main structure of the outer casing 110. The cover 112 covers the housing 111, thus forming a closed structure. The main board 120 is located within the housing 111, thereby protecting the main board 120 from the housing 111 and facilitating its installation and removal by personnel.

[0048] In some embodiments, as shown in FIG1, the edge of the housing 111 is provided with a flange, which is welded to the cover 112. This arrangement can make the cover 112 and the housing 111 more firmly connected, thereby ensuring the performance of the NFC access module 100 and making it easier for users to use the NFC function.

[0049] In some embodiments, as shown in FIG1, the housing 111 is provided with one of a positioning hole 121 and a positioning post, and the motherboard 120 is provided with the other of a positioning hole 121 and a positioning post. The positioning hole 121 and the positioning post are positioned and engaged, which facilitates the housing 111 to limit the motherboard 120, thereby facilitating the placement of the motherboard 120 within the housing 111. For example, the housing 111 is provided with a positioning post, and the motherboard 120 is provided with a positioning hole 121, with the positioning post and positioning hole 121 corresponding one-to-one, thereby facilitating the placement of the motherboard 120 within the housing 111.

[0050] Furthermore, as shown in Figure 1, a support rib 113 is provided on the side of the cover 112 facing the motherboard 120, and the support rib 113 contacts the motherboard 120. It can be understood that providing a support rib 113 on one side of the cover 112 can improve the structural strength of the cover 112. Moreover, the support rib 113 is positioned facing the motherboard 120, allowing it to abut against the motherboard 120, thereby reducing collisions between the cover 112 and the motherboard 120, extending the service life of the motherboard 120, and improving its performance.

[0051] As shown in Figures 4 and 5, the rearview mirror 200 according to a second aspect embodiment of this disclosure includes a mirror housing 210 and an NFC access module 100 as described above, with the NFC access module 100 disposed within the mirror housing 210. By providing a main board 120 within the housing 110 and an antenna board 130 outside the housing 110, and electrically connecting the antenna board 130 to the main board 120, the antenna board 130 does not occupy space within the housing 110, thereby saving space for the NFC access module 100. The antenna board 130 can be positioned close to the inner wall of the rearview mirror 200, thereby improving the performance of the NFC access module 100 and facilitating user access to the NFC function.

[0052] As shown in Figures 4 and 5, the antenna plate 130 is disposed on the inner surface of the mirror housing 210. The antenna plate 130 can be attached to the curved inner wall of the mirror housing 210, thereby increasing the usable area of ​​the antenna plate 130 for the user, and thus improving the performance of the NFC access module 100.

[0053] In some embodiments, as shown in FIG3, the antenna plate 130 is provided with at least one first fixing part 131, and the inner surface of the mirror housing 210 is provided with at least one second fixing part, wherein at least one first fixing part 131 is connected to at least one second fixing part. For example, the first fixing part 131 is fixed to the second fixing part by means of adhesive backing, hot melt, dispensing or screw connection, thereby facilitating the fixing of the antenna plate 130 to the inner surface of the mirror housing 210, and thus ensuring that the antenna plate 130 is always stably connected to the inner surface of the mirror housing 210 during vehicle movement.

[0054] As shown in Figure 3, the first fixing part 131 is constructed as a fixing hole, and the second fixing part is constructed as a fixing post integrally formed on the mirror housing 210. The fixing post passes through the fixing hole. This arrangement facilitates mutual positioning between the first fixing part 131 and the second fixing part, thereby facilitating the connection between the antenna plate 130 and the inner surface of the mirror housing 210, and thus enabling the antenna plate 130 to be stably installed in the rearview mirror 200.

[0055] In some embodiments, as shown in FIG3, at least one first fixing part 131 includes a plurality of first fixing parts 131, which are respectively disposed at the end corners of the antenna plate 130. At least one second fixing part includes a plurality of second fixing parts, and the plurality of first fixing parts 131 and the plurality of second fixing parts are connected in a one-to-one correspondence.

[0056] In other words, multiple first fixing parts 131 are located at the end corners of the antenna plate 130, and the multiple first fixing parts 131 and multiple second fixing parts are connected one-to-one, thereby making the connection between the antenna plate 130 and the inner surface of the mirror housing 210 more secure, and thus facilitating the user's use of the NFC function. For example, the first fixing parts 131 are fixed to the second fixing parts by means of adhesive, hot melt, dispensing, or screw connection, thereby facilitating the fixing of the antenna plate 130 to the inner surface of the mirror housing 210.

[0057] As shown in Figures 4 and 5, the antenna plate 130 is bonded to the inner surface of the mirror housing 210. This arrangement facilitates the connection between the antenna plate 130 and the inner surface of the mirror housing 210, thereby ensuring the stability between the antenna plate 130 and the inner surface of the mirror housing 210, and making it easier for users to use the NFC function.

[0058] In addition, as shown in Figure 5, the rearview mirror 200 also includes a mounting base 220, which is disposed within the mirror housing 210, and the outer casing 110 is disposed on the mounting base 220. It can be understood that the mounting base 220 is located within the mirror housing 210, and the outer casing 110 is disposed on the mounting base 220, thereby providing a mounting position for the outer casing 110, and thus making the connection between the outer casing 110 and the mounting base 220 more stable and secure.

[0059] As shown in Figures 1, 6, and 7, the vehicle 1000 according to the third aspect embodiment of this disclosure includes: the NFC access module 100 of the above embodiments, or the rearview mirror 200 of the above embodiments. By setting a main board 120 inside the housing 110 and setting an antenna board 130 outside the housing 110, and the antenna board 130 and the main board 120 are electrically connected, the antenna board 130 does not occupy the space of the housing 110, thereby saving the placement space of the NFC access module 100.
