[0026] See Figures 1 to 4 , Figure 1 This is a schematic diagram of an embodiment of the NFC card reader provided in this application; Figure 2 yes Figure 1 An exploded view of the NFC card reader in the embodiment; Figure 3 yes Figure 1 A first cross-sectional view of the NFC card reader in the embodiment; Figure 4 yes Figure 1 A first cross-sectional view of the NFC card reader in the embodiment. (See diagram below.) Figures 1 to 4 As shown, the NFC card reader 10 includes an upper cover 110, a lower housing 120, and an NFC module. The lower housing 120 forms an opening (not shown) and a receiving cavity (not shown) communicating with the opening. A portion of the bottom wall (not shown) of the lower housing 120, opposite to the opening, is recessed towards the receiving cavity to form a positioning post 121. The upper cover 110 covers the opening. The NFC module is disposed within the receiving cavity. The NFC module includes a circuit board 131 and an antenna board 132. The circuit board 131 and the antenna board 132 are spaced apart along the extending direction (not shown) of the positioning post 121 and are respectively engaged with the positioning post 121.
[0027] Understandably, a portion of the bottom wall of the lower housing 120 of this application is recessed toward the accommodating cavity to form a positioning post 121. The positioning post 121 is respectively engaged with the circuit board 131 and the antenna plate 132, so that the positioning post 121 can simultaneously position the circuit board 131 and the antenna plate 132. Furthermore, since the positioning post 121 is formed from a portion of the bottom wall of the lower housing 120, the additional components used to fix the antenna plate 132 and the circuit board 131 can be reduced, so that the accommodating cavity of the lower housing 120 does not need to consider the space for accommodating components, thereby reducing the size of the NFC card reader 10. In addition, the circuit board 131 and the antenna plate 132 are arranged along the extension direction of the positioning post 121, which can make full use of the accommodating space of the accommodating cavity, further reducing the size of the NFC card reader 10, thereby enabling the NFC card reader 10 to be used in narrow installation spaces.
[0028] In one embodiment, to enhance the limiting effect between the lower housing 120 and the circuit board 131 and antenna plate 132, a portion of the bottom wall of the lower housing 120 is recessed towards the accommodating cavity to form two spaced positioning posts 121. That is, in this embodiment, the lower housing 120 has two spaced positioning posts 121. These two spaced positioning posts 121 can restrict the movement of the circuit board 131 and antenna plate 132 in a direction perpendicular to the extension direction, thereby enhancing the stability of the positioning between the lower housing 120 and the circuit board 131 and antenna plate 132.
[0029] In one embodiment, the positioning post 121 includes a first post segment 1211 and a second post segment 1212 that are sequentially connected and coaxially arranged in the extending direction. The outer diameter of the first post segment 1211 is smaller than the outer diameter of the second post segment 1212. The first post segment 1211 and the second post segment 1212, which have different outer diameters, form a boss 1213 at their connection. The antenna plate 132 is provided with a first positioning hole 1321, which is sleeved on the first post segment 1211, and the antenna plate 132 is confined on the boss 1213. In this embodiment, the positioning post 121 comprises a first post segment 1211 and a second post segment 1212 arranged coaxially. A first positioning hole 1321 is fitted over the first post segment 1211. The first post segment 1211 can restrict the displacement of the antenna plate 132 in a direction perpendicular to the extension direction. Furthermore, the outer diameter of the first post segment 1211 is smaller than the outer diameter of the second post segment 1212, so that the first post segment 1211 and the second post segment 1212 form a boss 1213, which restricts the displacement of the antenna plate 132 toward the circuit board 131. The positioning post 121 of this embodiment can limit the antenna plate 132 in the extension direction and in a direction perpendicular to the extension direction, and has a simple structure and is easy to manufacture.
[0030] In one embodiment, the circuit board 131 is provided with a second positioning hole 1311, which is sleeved on the second column segment 1212. The inner wall of the accommodating cavity is provided with a first positioning rib 122, and the circuit board 131 is confined within the first positioning rib 122. The first positioning rib 122 can restrict the movement of the circuit board 131 towards the bottom of the accommodating cavity, and the second column segment 1212 can restrict the displacement of the circuit board 131 in a direction perpendicular to the extending direction. This embodiment, by providing the first positioning rib 122, can reduce the use of components for positioning and reduce the assembly steps of the NFC device.
[0031] In one embodiment, the positioning post 121 is located at the middle position of the lower housing 120, and the second positioning hole 1311 and the first positioning hole 1321 are located at the middle positions of the circuit board 131 and the antenna board 132, respectively. The middle position refers to a position near the center of the lower housing 120. The two positioning posts 121 can be spaced apart along the same direction, or they can be staggered.
[0032] In one embodiment, a limiting groove 111 is formed between the top wall of the upper cover 110 and the opening. The limiting groove 111 is correspondingly provided with a positioning post 121, and one end of the positioning post 121 facing away from the bottom wall is disposed in the limiting groove 111. The positioning post 121 facing away from the bottom wall and disposed in the limiting groove 111 can limit the displacement of the upper cover 110 relative to the opening, thereby increasing the ease of installation and portability of the upper cover 110 and the lower housing 120.
[0033] In one embodiment, the upper cover 110 also has an annular limiting rib 112, which is arranged around the periphery of the limiting groove 111 and abuts against the antenna plate 132. When the annular limiting rib 112 abuts against the antenna plate 132, the antenna plate 132 is clamped and positioned by the positioning post 121 and the annular limiting rib 112, so that the antenna plate 132 can be fixed in the accommodating cavity, improving the situation of antenna plate 132 shaking.
[0034] In one embodiment, the sidewall of the accommodating cavity is provided with a first through hole (not shown in the figure) communicating with the accommodating cavity. The NFC card reader 10 also includes a first connector 140, which is detachably electrically connected to the circuit board 131 and is used to access external signals. Specifically, the first end of the first connector 140 extends out of the accommodating cavity through the first through hole, and the second end of the first connector 140 extends towards the opening and onto the circuit board 131. Understandably, the accommodating cavity of the lower housing 120 communicates with the external environment through the first through hole, the first end of the first connector 140 is detachably electrically connected to the circuit board 131 by means of plugging or other methods, and the second end of the first connector 140 extends out of the lower housing 120 through the first through hole 128. This embodiment uses the first connector 140 to access external signals for power supply or communication connection to the NFC module; furthermore, the detachable electrical connection between the first connector 140 and the circuit board 131 facilitates the installation of the circuit board 131.
[0035] In one embodiment, the first connector 140 includes a rigid first connector 140, which facilitates installation with the circuit board 131.
[0036] In one embodiment, the first connector 140 is integrally formed with the lower housing 120, which enhances the connection stability between the first connector 140 and the lower housing 120 and reduces the number of installation steps. For example, the first connector 140 and the lower housing 120 are integrally formed by injection molding, in which case the first through hole is sealed by the first connector 140, which enhances the sealing performance of the accommodating cavity.
[0037] In one embodiment, the lower housing 120 is provided with an extension 124 extending away from the receiving cavity. The extension 124 surrounds and forms a receiving groove 1242 communicating with the first through hole. The first end of the first connector 140 extends into the receiving groove 1242. That is, the first connector 140 is electrically connected to an external power supply component within the receiving groove 1242, and the receiving groove 1242 can provide waterproof protection for the portion of the first connector 140 that is electrically connected to the external component.
[0038] In one embodiment, a snap fastener 1241 is formed on the outer wall of the extension 124. The NFC card reader 10 also includes a second connector 150, which is partially disposed within the receiving groove 1242 and is detachably electrically connected to the first end of the first connector 140, and is also engaged with the snap fastener 1241. That is, in this embodiment, the second connector 150 is detachably connected to the lower housing 120 via the snap fastener 1241, facilitating subsequent maintenance or care of the NFC module within the receiving cavity. The second connector 150, partially disposed within the receiving groove 1242, provides a certain degree of sealing to the receiving groove 1242, thereby enhancing the sealing performance of the receiving cavity.
[0039] In one embodiment, the card reader further includes a support member 160, which is located between the circuit board 131 and the antenna board 132. The support member 160 abuts against the circuit board 131 and the antenna board 132 respectively to fix the circuit board 131 and prevent the circuit board 131 from shaking due to normal product tolerances.
[0040] In one embodiment, the support member 160 may be a rubber support pad, which can deform under the action of force. The deformation of the rubber support pad can prevent slight shaking and abnormal noise caused by normal tolerances between the circuit board 131, the antenna board 132 and other components.
[0041] In one embodiment, the support member 160 includes an annular rubber support pad, which is sleeved on the positioning post 121. The positioning post 121 can also position the annular rubber support pad, eliminating the need for other means to position the annular rubber support pad.
[0042] In one embodiment, the upper cover 110 is provided with an ultrasonic welding line 123. Specifically, the ultrasonic welding line 123 may be provided at the connection between the upper cover 110 and the lower housing 120. The lower housing 120 is provided with a receiving cavity communicating with an opening and a mounting groove 113. The ultrasonic welding line 123 is embedded in the mounting groove 113 and welded to the inner wall of the mounting groove 113. Preferably, the receiving cavity and the mounting groove 113 are integrally formed.
[0043] Understandably, the NFC module is housed within the accommodating cavity of the lower housing 120. The ultrasonic welding line 123 of the upper cover 110 and the mounting groove 113 of the lower housing 120 are ultrasonically welded together, thereby sealing the accommodating cavity and thus sealing the NFC module. Ultrasonic welding utilizes high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces rub against each other, forming a fusion between molecular layers.
[0044] In the above manner, after the NFC module is placed in the accommodating cavity, the upper cover 110 and the lower housing 120 are ultrasonically welded so that the ultrasonic welding line 123 of the upper cover 110 and the inner wall of the mounting groove 113 of the lower housing 120 rub against each other and fuse together, thereby improving the sealing performance of the NFC card reader 10 and thus improving the stability of the NFC module's operation. Furthermore, the ultrasonic welding method of the ultrasonic welding line 123 of the upper cover 110 and the mounting groove 113 of the lower housing 120 can also prevent the upper cover 110 and the lower housing 120 from shifting, thus playing a limiting role.
[0045] In one embodiment, a second positioning rib 125 is also provided on the bottom wall of the accommodating cavity. The second positioning rib 125 has a larger dimension in the extending direction than the first positioning rib 122 in the extending direction, so that the second positioning rib 125 can limit the antenna plate 132.
[0046] In one embodiment, the edge of the circuit board 131 is provided with a groove 1313 with an opening facing the side wall of the receiving cavity, and the second positioning rib 125 is located in the groove 1313. The second positioning rib 125 can also limit the movement of the circuit board 131 in a direction perpendicular to the extension direction.
[0047] In one embodiment, the circuit board 131 may also be provided with an electrical connection hole 1312. The electrical connection hole 1312 can be used to provide a third connector electrically connected to the second end of the first connector 140, or the second end of the first connector 140 can be inserted into the electrical connection hole 1312, and the electrical connection hole 1312 abuts against the second end of the first connector 140. This is not limited in this respect. In this embodiment, the circuit board 131 achieves a detachable electrical connection with the first connector 140 by providing the electrical connection hole 1312.
[0048] In one embodiment, the NFC module includes a connector 133, with a female connector 133 disposed on a circuit board 131 and a male connector 133 disposed on an antenna board 132; or the male connector 133 is disposed on the circuit board 131 and the female connector 133 is disposed on the antenna board 132, which is not limited here. This embodiment achieves electrical connection between the antenna board 132 and the electronic components on the circuit board 131 by using the connector 133.
[0049] In one embodiment, the upper cover 110 and the lower housing 120 are made of insulating material. That is, the upper cover 110 and the lower housing 120 in this embodiment are injection molded parts. The housing material of the entire NFC card reader 10 does not contain metal, which is beneficial to the wireless signal transmission of the antenna board 132, thereby improving the stability of the NFC module operation.
[0050] In one embodiment, a mounting portion is provided on the outer peripheral sidewall of the lower housing 120, which is used to fix the NFC card reader 10.
[0051] Specifically, the mounting section includes a first mounting section 1261 and a second mounting section 1262, wherein the first mounting section 1261 and the second mounting section 1262 are arranged opposite to each other. The NFC card reader 10 of this embodiment can be installed inside the rearview mirror of a car. The protruding rib of the first mounting section 1261 obliquely supports the housing formed by the upper cover 110 and the lower housing 120, allowing the antenna plate 132 to approach the rearview mirror housing. This facilitates both the installation of the controller inside the mirror housing and the recognition of external signal input by the NFC module.
[0052] This application also provides a vehicle, see reference. Figure 5 , Figure 5 This is a structural schematic diagram of an embodiment of the vehicle provided in this application, as shown below. Figure 5 As shown, the vehicle 20 includes an NFC card reader (not labeled), wherein the NFC card reader is any one of the NFC card reader devices described in the above embodiments. The NFC card reader can be installed inside the rearview mirror.
