Description

Technical Field

[0001] This disclosure relates to the field of terminal device technology, and in particular to a near field communication (NFC) component, a back cover component, and a terminal device. Background Technology

[0002] With the development of terminal devices, the performance requirements for Near Field Communication (NFC) components are becoming increasingly stringent. In related technologies, NFC components can be assembled from the front or back of the terminal device's back cover. However, regardless of whether it's front or back assembly, the wiring is routed in a way that avoids screws, resulting in a large space requirement for the NFC component. Summary of the Invention

[0003] To overcome the problems existing in related technologies, this disclosure provides a near-field communication (NFC) component, a back cover component, and a terminal device.

[0004] According to a first aspect of the present disclosure, a near-field communication (NFC) component is provided, comprising:

[0005] Flexible circuit board;

[0006] The NFC unit is connected to the flexible circuit board;

[0007] Grounding components are connected to the NFC body at different locations on the flexible circuit board;

[0008] The grounding element has a first screw hole for the screws of the rear housing to pass through.

[0009] In this embodiment of the disclosure, by providing a first screw hole for the screws of the rear cover to pass through, not only can the space occupied by the NFC component be reduced, and the impact on other components (such as battery capacity) in the terminal device be reduced when the NFC component is applied to the terminal device, but the strength of the NFC component can also be improved without having to avoid the screws, thus improving the assembly reliability of the NFC component.

[0010] In some embodiments, the grounding element includes a grounding spring;

[0011] The first screw hole is located at the first end of the grounding spring along the first direction.

[0012] In this embodiment of the disclosure, the grounding element is set as a grounding spring, and the first screw hole is set at the first end of the grounding spring along the first direction, which can further reduce the space occupied by the NFC component while facilitating assembly.

[0013] In some embodiments, the NFC component has at least one positioning hole;

[0014] At least one of the positioning holes is disposed at the second end of the grounding spring along the first direction, and the second end is disposed opposite to the first end.

[0015] In this embodiment, the positioning hole and the first screw hole are respectively set at different ends of the grounding spring along the first direction, which can not only better position it during assembly, but also eliminate the need to avoid the screw during assembly, thus reducing the space occupied.

[0016] In some embodiments, there are multiple positioning holes;

[0017] The plurality of positioning holes are spaced apart at the second end along a second direction, which intersects with the first direction.

[0018] In this embodiment, better positioning can be achieved by providing multiple positioning holes. Furthermore, by distributing multiple positioning holes along the second direction at the second end, better layout of the positioning holes can be achieved.

[0019] In some embodiments, the grounding spring has a clearance notch on its side along the first direction;

[0020] The clearance notch is spaced apart from the first screw hole.

[0021] In this embodiment of the disclosure, by providing an avoidance notch on the grounding spring, the grounding spring can better avoid spatial obstacles, thereby enabling better assembly of the NFC component.

[0022] In some embodiments, the NFC component further includes a reinforcing layer having a second screw hole;

[0023] The reinforcing layer covers at least a portion of the grounding element, and the second screw hole is aligned with the first screw hole.

[0024] In this embodiment of the present disclosure, by providing a second screw hole on the reinforcing layer so that the second screw hole is aligned with the first screw hole, the screws of the rear shell can pass through the second screw hole and the first screw hole during assembly. This allows the screws to be avoided even when a reinforcing layer is provided, thus reducing the space occupied by the NFC component.

[0025] In some embodiments, the NFC component further includes an adhesive layer having a third screw hole;

[0026] The adhesive layer covers the side of the reinforcing layer opposite to the grounding member, and the third screw hole is aligned with the first screw hole and the second screw hole, respectively.

[0027] In this embodiment of the present disclosure, by providing a third screw hole on the adhesive layer, the three screw holes are aligned with the first screw hole and the second screw hole respectively. Thus, during assembly, the screws of the rear shell can pass through the third screw hole, the second screw hole and the first screw hole. This allows the screws to be avoided even when an adhesive layer is provided, reducing the space occupied by the NFC component.

[0028] In some embodiments, the flexible circuit board is in a bent state, and the bent flexible circuit board has a third end and a fourth end;

[0029] The grounding element is connected to the third end;

[0030] The NFC body is connected to the fourth end.

[0031] In this embodiment of the disclosure, by setting a flexible circuit board in a bent state, and setting a grounding component and an NFC body at the third end and the fourth end respectively, the NFC component can be better installed on the back cover of the terminal device.

[0032] According to a second aspect of the present disclosure, a rear shell assembly is provided, comprising:

[0033] Back cover;

[0034] The NFC component as described in the first aspect above is disposed on the rear cover;

[0035] The screws on the rear housing pass through the first screw hole of the grounding element in the NFC assembly.

[0036] In some embodiments, after passing through the first screw hole, the screw of the rear housing passes sequentially through the second screw hole in the reinforcing layer of the NFC assembly and the third screw hole in the adhesive layer.

[0037] In some embodiments, a grounding positioning post is formed on the first side of the rear housing; the grounding positioning post passes through the positioning hole of the NFC component.

[0038] In some embodiments, an antenna positioning structure is formed at the intersection of the second and third sides of the rear shell;

[0039] The antenna positioning structure is used to locate the NFC body of the NFC component;

[0040] Wherein, the second side and the first side of the rear shell are opposite sides disposed in the rear shell, and the third side is an adjacent side connected between the first side and the second side.

[0041] In some embodiments, the rear housing is formed with a camera hole;

[0042] The grounding element of the NFC component and the camera hole are located on the same side of the rear cover.

[0043] According to a third aspect of the present disclosure, a terminal device is provided, comprising: a rear shell assembly as described in the first aspect above; or an NFC component as described in the second aspect above.

[0044] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0045] In this embodiment of the disclosure, the grounding part of the NFC component has a first screw hole, so that when the NFC component is assembled into the back cover, the screws of the back cover can pass through the first screw hole, and there is no need to bend the wiring to avoid the screws, which would increase the space occupied by the NFC component.

[0046] In other words, the grounding component in this embodiment can be used both as a ground for the NFC component and, by providing the first screw hole, facilitate the assembly of the NFC component, thus achieving a dual function. Furthermore, by providing the first screw hole for the screws of the rear cover to pass through, this embodiment not only reduces the space occupied by the NFC component and minimizes its impact on other components (such as battery capacity) in the terminal device when applied to it, but also eliminates the need to compromise the strength of the NFC component to avoid screws, thereby improving the assembly reliability of the NFC component.

[0060] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0061] This disclosure provides an NFC component. This NFC component can be applied to terminal devices, enabling them to communicate with other devices at near range for purposes such as payment, transportation, and identity verification.

[0062] Figure 1 This is a schematic diagram illustrating the structure of an NFC component according to an exemplary embodiment. Figure 2 This is a schematic diagram illustrating the structure of an NFC component assembled on a back cover according to an exemplary embodiment. Figure 1 and Figure 2 As shown, the NFC component 100 includes:

[0063] Flexible circuit board 101;

[0064] NFC body 102 is connected to the flexible circuit board 101;

[0065] Grounding component 103 is connected to the NFC body 102 at different locations on the flexible circuit board 101;

[0066] The grounding member 103 has a first screw hole 104 for the screws of the rear housing 200 to pass through.

[0067] In this embodiment, the NFC component can be assembled from the front of the back cover of the terminal device, making it suitable for scenarios where the terminal device has a large demand for battery space. For example, when the terminal device uses a large-capacity battery, the NFC component of this disclosure can be assembled into the back cover, reducing the space occupied by the NFC component and allowing the terminal device to have more space to accommodate the large-capacity battery.

[0068] The aforementioned flexible circuit board not only provides electrical connections but can also serve as a carrier for antenna circuits (such as matching circuits) in NFC components. The shape of the flexible circuit board can be configured according to the wiring layout requirements. For example, the flexible circuit board can be L-shaped or U-shaped, and this disclosure does not limit its shape.

[0069] The aforementioned NFC unit is used to transmit and receive NFC signals to achieve short-range communication. This NFC unit can be constructed from a coil made of wire (such as copper wire).

[0070] Here, the NFC body can be disposed on a flexible circuit board or connected to the end of the flexible circuit board, and this disclosure does not limit this.

[0071] The aforementioned grounding components can be directly connected to the grounding layer of the motherboard in the terminal equipment, or they can be connected to the grounding layer of the motherboard through a shielding component, serving the functions of circuit protection and signal stabilization.

[0072] Here, the shielding component can be a shielding cover, which can be placed over the functional components of the terminal device (such as a WIFI antenna assembly) to shield the signal of the covered functional components and reduce interference.

[0073] It should be noted that this grounding component is a conductive component used to transmit NFC signals to the ground plane of the motherboard. Here, the grounding component may include a grounding spring or grounding foam.

[0074] The aforementioned grounding component and NFC body can be connected to different locations on the flexible circuit board. For example, the grounding component and NFC body can be connected to different ends of the flexible circuit board. Alternatively, one of the grounding component and NFC body can be connected to one end of the flexible circuit board, and the other can be connected between two ends of the flexible circuit board.

[0075] The aforementioned grounding element has a first screw hole for the screws of the rear housing to pass through.

[0076] Here, the size of the first screw hole is adapted to the size of the screw. For example, the size of the first screw hole is set to be greater than or equal to the size of the screw so that the screw of the rear housing can pass through the first screw hole more easily.

[0077] Of course, the shape of the first screw hole is also adapted to the shape of the screw. For example, the first screw hole is set to be a round hole adapted to the screw.

[0078] In this embodiment, the first screw hole is located at the grounding component and can be set according to the screw on the back cover. This allows the screw on the back cover to pass through the first screw hole when the NFC component is assembled on the back cover, thereby eliminating the need for the NFC component to avoid the screw and reducing the space occupied by the NFC component.

[0079] For example, such as Figure 3a and 3b As shown, the NFC component can be assembled from the front of the back cover. However, during the assembly of the NFC component, the avoidance traces 30 are designed to avoid the screws, which results in a large space occupation problem, which in turn affects the NFC trace layout, the internal stacking space of the terminal device, and the battery capacity.

[0080] like Figure 3c As shown, the NFC component can also be assembled from the back of the back cover, meaning the NFC component has a routing path 40 to reach the front of the back cover. This assembly method is more difficult and requires avoiding screws, which not only limits the width of the NFC component, affecting its reliability, but also results in a larger footprint, impacting the battery capacity within the terminal device. For example, in designs with high battery capacity requirements and limited internal stacking space in terminal devices, the larger space occupied by the NFC component leads to a smaller battery capacity for the same terminal device size.

[0081] Based on this, the present disclosure proposes an NFC component in which the grounding part of the NFC component has a first screw hole. Thus, when the NFC component is assembled into the back cover, it can be directly assembled so that the screw of the back cover passes through the first screw hole, without the need to bend the wiring to avoid the screw, which would increase the space occupied by the NFC component.

[0082] In other words, the grounding component in this embodiment can be used both as a ground for the NFC component and, through the first screw hole, facilitate the assembly of the NFC component, achieving a dual function. Furthermore, by providing the first screw hole for the screws of the rear housing to pass through, this embodiment not only reduces the space occupied by the NFC component and minimizes its impact on other components (such as battery capacity) in the terminal device when applied to it, but also avoids compromising the strength of the NFC component to avoid the screws, thus improving the assembly reliability of the NFC component. Of course, this embodiment also saves costs because it eliminates the need for bending wiring to avoid the screws.

[0083] In some embodiments, such as Figure 1 and Figure 2 As shown, the grounding element 103 includes a grounding spring;

[0084] The first screw hole 104 is disposed at the first end of the grounding spring along the first direction A.

[0085] In this embodiment of the disclosure, the grounding element includes a grounding spring, which may be a rectangular spring or other irregularly formed spring, and this embodiment of the disclosure does not limit this.

[0086] The aforementioned first screw hole is disposed at the first end of the grounding spring along the first direction. When the grounding spring is rectangular, the first direction can be the length direction of the grounding spring, that is, the first screw hole can be disposed at any end of the grounding spring along the length direction of the grounding spring.

[0087] In this embodiment of the disclosure, during the assembly of the NFC component onto the back cover of the terminal device, the grounding spring can be disposed on the back cover along the extension direction of the side of the back cover. Here, the length direction of the grounding spring can be the same as the extension direction of the side of the back cover.

[0088] It is understood that in this embodiment of the present disclosure, the grounding element is set as a grounding spring, and the first screw hole is set at the first end of the grounding spring along the first direction, which can further reduce the space occupied by the NFC component while facilitating assembly.

[0089] In some embodiments, such as Figure 1 and Figure 2 As shown, the NFC component 100 has at least one positioning hole 105;

[0090] At least one of the positioning holes 105 is disposed at the second end of the grounding spring along the first direction A, and the second end is disposed opposite to the first end.

[0091] In this embodiment of the disclosure, when assembling the NFC component onto the back cover, the positioning hole is used for positioning the grounding component, enabling the NFC component to complete the assembly more effectively.

[0092] It should be noted that when multiple positioning holes are set, these multiple positioning holes can be set at intervals at the second end to achieve more reliable positioning of the grounding component.

[0093] For example, the number of positioning holes may be set to two or more, and this disclosure does not limit the number of such holes.

[0094] In this embodiment, the positioning hole is provided at the second end, and the second end and the first end are two ends that are opposite to each other. Therefore, the positioning hole and the first screw hole are respectively provided at two different ends of the grounding spring along the first direction. This means that the grounding spring is positioned at one end along the first direction through the positioning hole, and the grounding spring is also better assembled through the first screw hole at the other end.

[0095] In other words, by providing a first screw hole and a positioning hole on the grounding spring, the present disclosure embodiment achieves three functions in one: grounding, positioning, and better assembly.

[0096] It is understood that in this embodiment of the present disclosure, the positioning hole and the first screw hole are respectively set at different ends of the grounding spring along the first direction, which can not only better position during assembly, but also eliminate the need to avoid the screw during assembly, thus reducing the space occupied.

[0097] In some embodiments, such as Figure 1 and Figure 2 As shown, there are multiple positioning holes 105;

[0098] The plurality of positioning holes 105 are spaced apart at the second end along the second direction B, and the second direction B intersects the first direction A.

[0099] In this embodiment, a plurality of positioning holes are spaced apart at the second end along a second direction. The spacing between two adjacent positioning holes can be set according to actual conditions, and this embodiment does not impose any limitations.

[0100] It should be noted that the intersection of the second direction and the first direction can include: the angle between the first direction and the second direction can be an obtuse angle, an acute angle, or a right angle.

[0101] For example, the angle between the second direction and the first direction can be a right angle, and when the first direction is the length direction of the grounding spring, the second direction can be the width direction of the grounding spring.

[0102] It is understood that, in this embodiment of the present disclosure, better positioning can be achieved by providing multiple positioning holes. Furthermore, by providing multiple positioning holes distributed along the second direction at the second end, better layout of the positioning holes can be achieved.

[0103] In some embodiments, such as Figure 1 and Figure 2 As shown, the side of the grounding spring piece along the first direction A has an avoidance notch 106;

[0104] The clearance notch 106 is spaced apart from the first screw hole 104.

[0105] In this embodiment of the disclosure, the clearance gap can be formed by the inward indentation of the side edge of the grounding spring along the first direction.

[0106] Here, the clearance notch of the grounding spring can be used to avoid functional components of the terminal equipment, including but not limited to conductive connectors disposed between the shield and the grounding spring.

[0107] It should be noted that the size and shape of the clearance gap can be set according to the functional device that needs to be cleared, and this embodiment does not limit this.

[0108] For example, the shape of the clearance can be set to a semi-circle or a semi-elliptical arc.

[0109] For example, the clearance notch can be set close to the positioning hole, or the clearance notch can be set close to the first screw hole.

[0110] In this embodiment of the disclosure, when the grounding spring also has a positioning hole, the clearance notch can be spaced apart from both the first screw hole and the positioning hole. Here, the clearance notch can be located between the first screw hole and the positioning hole. When assembling the NFC component onto the back cover of the terminal device, the clearance notch can face outwards from the terminal device.

[0111] It should be noted that when the grounding spring is rectangular and the first direction is the length direction of the grounding spring, the side of the grounding spring provided along the first direction has an avoidance notch, which may include: any long side of the grounding spring has an avoidance notch.

[0112] In this embodiment, the grounding spring can serve as a grounding element for the NFC component. It can also reduce space usage by providing a first screw hole, eliminating the need for screw avoidance, and can perform positioning by providing a positioning hole and avoidance notch. In other words, this embodiment achieves four functions in one: grounding spring.

[0113] It is understood that, in this embodiment of the present disclosure, by providing an avoidance notch on the grounding spring, the grounding spring can better avoid spatial obstacles, thereby enabling better assembly of the NFC component.

[0114] In some embodiments, such as Figure 1 and Figure 2As shown, the NFC component 100 also includes a reinforcing layer 107 having a second screw hole 108;

[0115] The reinforcing layer 107 covers a portion of the grounding member 103, and the second screw hole 108 is aligned with the first screw hole 104.

[0116] In this embodiment of the present disclosure, the grounding member may form a grounding portion having a first screw hole, and when the reinforcing layer covers a portion of the grounding member, the reinforcing layer may cover the grounding portion.

[0117] Here, the second screw hole can be the same as the first screw hole, that is, the second screw hole can be the same as the first screw hole in both size and shape. Of course, the size of the second screw hole can also be larger than the size of the first screw hole.

[0118] In this embodiment, when the reinforcing layer covers all grounding components, in addition to the second screw hole, the reinforcing layer also needs to have a positioning hole and a clearance notch. In this case, the positioning hole of the reinforcing layer aligns with the positioning hole of the grounding spring, and the clearance notch of the reinforcing layer aligns with the positioning notch of the grounding spring. Thus, this embodiment can achieve better assembly of the NFC component based on the provision of the reinforcing layer.

[0119] In this embodiment, the reinforcing layer may include a metal plate or a non-metallic component. The non-metallic component may be formed from polyimide film, carbon fiber composite material, ceramic-filled plastic, etc., and this disclosure does not impose any limitations thereon.

[0120] It is understood that, in this embodiment of the present disclosure, by providing a second screw hole on the reinforcing layer so that the second screw hole is aligned with the first screw hole, the screws of the back cover can pass through the second screw hole and the first screw hole during assembly. This allows the screws to be avoided even when a reinforcing layer is provided, thus reducing the space occupied by the NFC component.

[0121] In some embodiments, such as Figure 1 and Figure 2 As shown, the NFC component also includes an adhesive layer (not shown) with a third screw hole;

[0122] The adhesive layer covers the side of the reinforcing layer 107 opposite to the grounding member 103, and the third screw hole is aligned with the first screw hole 104 and the second screw hole 108, respectively.

[0123] In this embodiment, the third screw hole is aligned with the first screw hole and the second screw hole, respectively. That is, the first screw hole, the second screw hole, and the third screw hole are three aligned screw holes, all used for the screws of the rear housing to pass through.

[0124] Here, the third screw hole can be the same as the first screw hole and the second screw hole; of course, the size of the third screw hole can also be larger than the size of the first screw hole, or the size of the third screw hole can also be larger than the size of the second screw hole.

[0125] In this embodiment, the adhesive layer is used to bond the NFC component to the back cover. Here, the adhesive layer can be understood as backing adhesive, and the NFC component can be fixed by activating the backing adhesive through pressure holding.

[0126] In this embodiment of the present disclosure, when the reinforcing layer covers a portion of the grounding member, that is, when the reinforcing layer covers the grounding portion having the first screw hole, the adhesive layer may be provided with a third screw hole.

[0127] When the reinforcing layer covers the entire grounding component, the adhesive layer, in addition to the third screw hole, also forms positioning holes and clearance notches. In this case, the positioning holes of the adhesive layer are aligned with the positioning holes of the grounding component and the reinforcing layer, respectively; the clearance notches of the adhesive layer are aligned with the clearance notches of the grounding component and the reinforcing layer, respectively. Thus, this embodiment of the present disclosure can achieve better assembly of the NFC component by providing the reinforcing layer and adhesive layer.

[0128] It is understood that, in this embodiment of the present disclosure, by providing a third screw hole on the adhesive layer so that the three screw holes are aligned with the first screw hole and the second screw hole respectively, the screws of the back cover can pass through the third screw hole, the second screw hole and the first screw hole during assembly. This allows the screws to be avoided even when an adhesive layer is provided, thus reducing the space occupied by the NFC component.

[0129] In some embodiments, such as Figure 1 As shown, the flexible circuit board 101 is in a bent state, and the bent flexible circuit board 101 has a third end and a fourth end;

[0130] The grounding component 103 is connected to the third end;

[0131] The NFC body 102 is connected to the fourth end.

[0132] In this embodiment of the disclosure, the flexible circuit board is in a bent state. The flexible circuit board may be a flexible circuit board having at least one bending angle. For example, such as... Figure 1 As shown, the flexible circuit board 101 has three bending angles.

[0133] It should be noted that the grounding component is connected to the third end, and the NFC body is connected to the fourth end. In other words, the grounding component and the NFC body are respectively located at two different ends of the flexible circuit board.

[0134] Here, as Figure 1As shown, a support member 109 and a ferrite 110 may also be provided on the flexible circuit board. The support member 109 can be used to improve the strength of the flexible circuit board from a mechanical structure perspective; the ferrite 110 can be used to optimize electromagnetic performance and improve the signal quality of the NFC component.

[0135] It is understood that, in this embodiment of the present disclosure, by setting a flexible circuit board in a bent state, and by setting the grounding component and the NFC body at the third end and the fourth end respectively, the NFC component can be better installed on the back cover of the terminal device.

[0136] This disclosure also proposes a rear shell assembly, such as... Figure 1 , Figures 4 to 8 As shown, the rear shell assembly includes:

[0137] Back cover 200;

[0138] As in one or more of the above embodiments, the NFC component 100 is disposed on the rear cover 200;

[0139] The screws of the back cover 200 pass through the first screw hole 104 of the grounding element 103 in the NFC assembly 100.

[0140] In this embodiment of the disclosure, the flexible circuit board of the NFC component can be disposed in the mounting cavity formed by the rear shell. The mounting cavity can not only be used to accommodate the flexible circuit board, but also to limit the position of the flexible circuit board.

[0141] The NFC body of the aforementioned NFC component can be located at the intersection of the two sides of the rear cover, and the grounding component of the NFC component can be located on one side of the rear cover.

[0142] In this embodiment of the disclosure, the NFC component can be assembled from the front of the back cover onto the antenna positioning structure and grounding positioning post of the back cover. After the NFC component is assembled, auxiliary materials such as wireless charging coil, graphite for heat dissipation, and foam can be assembled on the back cover to complete the assembly process of the back cover component.

[0143] It is understood that the back cover assembly includes an NFC component. The grounding element in the NFC component can serve both as a ground for the NFC component and, through the first screw hole, facilitate the assembly of the NFC component, thus achieving a dual function. Furthermore, by providing the first screw hole for the screws of the back cover to pass through, this embodiment of the present disclosure not only minimizes the space occupied by the NFC component and reduces the impact on other components (such as battery capacity) in the terminal device when the NFC component is used, but also avoids compromising the strength of the NFC component by avoiding the screws, thereby improving the assembly reliability of the NFC component.

[0144] In some embodiments, such as Figures 4 to 6As shown, after passing through the first screw hole 104, the screw of the rear shell 200 passes through the second screw hole 108 of the reinforcing layer in the NFC assembly and the third screw hole of the adhesive layer in sequence.

[0145] It is understood that, in this embodiment of the present disclosure, by setting the screws of the rear shell to pass through the first screw hole, the second screw hole and the third screw hole in sequence, the screws can be avoided even when the grounding component is stacked with a reinforcing layer and an adhesive layer, thus reducing the space occupied by the NFC component.

[0146] In some embodiments, such as Figure 1 , Figures 4 to 6 As shown, a grounding positioning post (not shown in the figure) is formed on the first side of the rear cover 200; the grounding positioning post passes through the positioning hole 105 of the NFC component 100.

[0147] It is understood that in this embodiment of the present disclosure, a grounding positioning post is provided on the rear shell, which can pass through the positioning hole, thereby improving the assembly reliability of the grounding component.

[0148] In some embodiments, such as Figure 1 , Figures 4 to 6 As shown, the rear shell 200 has an antenna positioning structure 201 formed at the intersection of the second and third sides;

[0149] The antenna positioning structure 201 is used to position the NFC body 102 of the NFC component 100.

[0150] The second side and the first side are opposite sides disposed in the rear shell, and the third side is an adjacent side connected between the first side and the second side.

[0151] In this embodiment, the antenna positioning structure may include two antenna positioning posts, such that the NFC body is clamped between the two antenna positioning posts. Alternatively, the antenna positioning structure can be directly configured as a positioning clip to position the NFC body at the intersecting position.

[0152] It is understood that in this embodiment of the present disclosure, an antenna positioning structure is provided on the rear shell, which can be used to position the NFC body and improve the assembly reliability of the NFC body.

[0153] In some embodiments, such as Figure 5 As shown, the rear shell 200 has a camera hole 202 formed therein;

[0154] The grounding component 103 of the NFC component 100 and the camera hole 202 are located on the same side of the rear cover 200.

[0155] It is understood that, in this embodiment of the present disclosure, by placing the grounding component of the NFC component and the camera hole on the same side of the back cover, the NFC component can be more reasonably assembled on the back cover.

[0156] This disclosure also proposes a terminal device that includes a back cover component of one or more of the above embodiments, or includes an NFC component of one or more of the above embodiments.

[0157] In this embodiment of the disclosure, the terminal device further includes: a motherboard and a shielding cover; and a grounding component for the NFC component, which is connected to the grounding layer of the motherboard through the shielding cover.

[0158] It is understood that the terminal device includes an NFC component. The grounding component in the NFC component can serve both as a ground for the NFC component and, by providing the first screw hole, facilitate the assembly of the NFC component, thus achieving a dual function. Furthermore, by providing the first screw hole for the screws of the rear cover to pass through, the embodiments of this disclosure not only minimize the space occupied by the NFC component and reduce the impact on other components (such as battery capacity) in the terminal device when the NFC component is used, but also eliminate the need to compromise the strength of the NFC component to avoid the screws, thereby improving the assembly reliability of the NFC component.

[0159] As verified, such as Figure 7 As shown, a traditional NFC component is applied to a terminal device. The length L1 of the terminal device is 152.3 mm, the dimension L2 of the battery along the length of the terminal device is 75.9 mm, and the battery capacity can be 5400 mAh.

[0160] like Figure 8 As shown, the NFC component of this embodiment is applied to a terminal device, and the length L3 of the terminal device is 151.1 mm. Because the NFC component of this embodiment has a first screw hole, the NFC component does not need to avoid the screw when assembled onto the back cover. Therefore, no wiring space around the screw is required between the battery and the camera, allowing the battery dimension L4 along the length of the terminal device to be 87.56 mm.

[0161] Therefore, through comparison Figure 7 The arrow points to the wiring of traditional NFC components and Figure 8 As can be seen from the layout of the NFC component of this disclosure indicated by the arrow, the NFC component of this embodiment of the disclosure, due to the provision of the first screw hole, can increase the size of the battery along the length direction of the terminal device by 11.66 mm, thereby increasing the battery capacity by 1500mAh.

[0162] Based on this, the NFC component with a first screw hole designed in this embodiment can not only solve the problem of large space occupation and impact on battery capacity caused by front-mounted traditional NFC components, but also solve the problems of poor reliability and space utilization caused by back-mounted traditional NFC components. It can save stacking space of terminal devices, improve the space utilization of motherboard and battery in terminal devices and increase battery capacity, making terminal devices more competitive.
