[0031] Combine the following Figures 1 to 10 The case assembly 100 and the electronic device according to the embodiment of the present application are described.
[0032] like Figure 1 , Figure 2 , Figure 5 and Figure 8As shown, the present application provides a shell assembly 100, including: a shell 110; a coil 120, which is arranged on the shell 110, and the coil 120 has a first connection port 121; a metal decorative part 130, which is arranged on the shell 110, and the metal decorative part 130 has a second connection port 131; a connecting component 140, and the connecting component 140 is used to connect the two ends of the first connection port 121 with the two ends of the second connection port 131 respectively, so that the coil 120 and the metal decorative part 130 form a closed conductive loop together, and when the coil 120 and the metal decorative part 130 are electrically connected, the current directions in the metal decorative part 130 and the coil 120 are the same; wherein, along the direction perpendicular to the surface of the shell 110, the projection of the coil 120 on the surface of the shell 110 partially overlaps with the projection of the metal decorative part 130 on the surface of the shell 110, and the coil 120 is a near field communication coil.
[0033] In an embodiment of the present application, the shell assembly 100 includes a shell 110, a coil 120 and a metal decorative part 130. The coil 120 and the metal decorative part 130 are both mounted on the shell 110, and the coil 120 can be energized to generate a magnetic field so that the coil 120 can sense an external device, thereby enabling the coil 120 to have functions such as card reading or identification. Understandably, the card reading accuracy of the coil 120 is related to the magnetic flux and induction area of the coil 120. The larger the vertical magnetic field area of the coil 120, the larger the magnetic flux generated by the coil 120, and the coil 120 can read and identify the card more accurately. Since the metal decorative part 130 is also arranged on the shell 110, the metal decorative part 130 will occupy the installation space of the coil 120, thereby reducing the size of the coil 120. In order to prevent the metal decorative part 130 from occupying the installation space of the coil 120, resulting in a reduction in the induction area of the coil 120 and a reduction in the magnetic flux of the coil 120, the present application provides a structure in the shell assembly 100 for increasing the induction area and magnetic flux of the coil 120.
[0034] Furthermore, the shell assembly 100 further includes a connection assembly 140, the metal decorative part 130 is conductive, and the connection assembly 140 is used to connect the metal decorative part 130 with the coil 120, so that the metal decorative part 130 is connected to the conductive circuit of the coil 120 through the connection assembly 140, thereby making the metal decorative part 130 and the coil 120 together form a closed conductive circuit. When the coil 120 and the metal decorative part 130 are electrically connected, the current direction in the metal decorative part 130 is the same as that in the coil 120. Specifically, the coil 120 and the metal decorative part 130 are both non-closed structures, the coil 120 has a first connection port 121, the metal decorative part 130 has a second connection port 131, the connection assembly 140 is conductive, and the connection assembly 140 is used to connect the two ends of the first connection port 121 to the two ends of the second connection port 131, respectively, so that the metal decorative part 130 can be connected to the conductive circuit of the coil 120 through the connection assembly 140. The current flowing through the coil 120 flows to the metal decoration part 130 through the connecting component 140 , and then flows back to the coil 120 through the connecting component 140 , thereby making the metal decoration part 130 and the coil 120 form a closed conductive loop together.
[0035] Further, along the direction perpendicular to the surface of the housing 110, the projection of the coil 120 on the surface of the housing 110 partially overlaps with the projection of the metal decorative part 130 on the surface of the housing 110. The first connection port 121 and the second connection port 131 may be arranged in the area where the projections of the coil 120 and the metal decorative part 130 intersect, so as to facilitate connecting the coil 120 to the metal decorative part 130 through the connection assembly 140. By arranging the coil 120 and the metal decorative part 130 to partially overlap the projections on the surface of the housing 110, the installation space of the coil 120 can be increased, thereby increasing the magnetic flux of the coil 120, improving the magnetic induction intensity of the coil 120, and thereby improving the induction capability and card reading capability of the coil 120 with the external device, thereby improving the convenience of use for the user.
[0036] Further, the coil 120 is a near field communication coil, that is, the coil 120 in the present application is an NFC coil, so that the coil 120 can sense the device at a relatively close distance, so that the coil 120 has the functions of sensing and card reading. Since the coil 120 and the metal decorative part 130 together constitute a closed conductive loop, the sensing area of the coil 120 is increased, the magnetic flux of the coil 120 is increased, and the magnetic induction intensity of the coil 120 is improved, thereby improving the sensing ability and card reading ability of the coil 120 with the external device, and improving the user's convenience. By setting a connecting component 140 in the shell component 100, the coil 120 is connected to the metal decorative part 130 through the connecting component 140, so that the metal decorative part 130 can be connected to the conductive loop of the coil 120 through the connecting component 140, so that the metal decorative part 130 and the coil 120 form a closed conductive loop together. In this way, the sensing area and magnetic flux of the coil 120 can be increased, the accuracy of the card reading and sensing of the coil 120 can be improved, and the user's experience can be improved.
[0037] like Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, as a possible implementation, along a direction perpendicular to the surface of the housing 110 , the height of the metal decoration part 130 is higher than the height of the coil 120 .
[0038] Specifically, the metal decorative piece 130 protrudes from the surface of the housing 110, and the height of the metal decorative piece 130 is higher than the height of the coil 120 in a manner perpendicular to the surface of the housing 110. Understandably, when a user senses an external device or reads a card through the coil 120, the coil 120 needs to be brought close to the sensed device. Since the height of the metal decorative piece 130 is higher than the height of the coil 120, the distance between the metal decorative piece 130 and the sensed device is smaller than the distance between the coil 120 and the sensed device.
[0039] Understandably, the smaller the distance between the coil 120 and the induced device, the higher the induction effect of the coil 120 on the device. Since the metal decorative part 130 is connected to the conductive loop of the coil 120 through the connecting component 140, the distance between the conductive loop formed by the coil 120 and the metal decorative part 130 and the induction device can be reduced through the metal decorative part 130, reducing the induction distance loss between the coil 120 and the device caused by the protrusion of the metal decorative part 130, thereby improving the induction effect of the coil 120 on the device.
[0040] like Figure 2 , Figure 3 and Figure 4As shown, as a possible embodiment, the coil 120 is arranged adjacent to the metal decorative part 130, and the connecting component 140 includes: a first connecting part 141; a second connecting part 142, the first connecting part 141 and the second connecting part 142 are respectively connected to the two ends of the second connecting port 131 and extend in the direction toward the coil 120, and the first connecting part 141 and the second connecting part 142 are respectively connected to the two ends of the first connecting port 121.
[0041] Specifically, the structure of the connection component 140 is defined. As a possible implementation, the coil 120 is disposed adjacent to the metal decorative member 130, that is, there is no overlapping area between the coil 120 and the metal decorative member 130. The connection component 140 includes a first connection member 141 and a second connection member 142, both of which are connected to the metal decorative member 130, wherein the first connection member 141 and the second connection member 142 are respectively connected to the two ends of the second connection port 131 on the metal decorative member 130, and both of the first connection member 141 and the second connection member 142 extend in a direction toward the coil 120, so as to facilitate the connection of the coil 120 with the metal decorative member 130. Furthermore, the first connecting member 141 and the second connecting member 142 are both conductive, and the first connecting member 141 and the second connecting member 142 are respectively connected to the two ends of the first connecting port 121. In this way, the metal decorative member 130 can be connected to the coil 120 through the connecting component 140, thereby making the metal decorative member 130 and the coil 120 form a closed conductive loop together.
[0042] The direction of the current in the closed conductive loop formed by the metal decorative part 130 and the coil 120 is as follows: Figure 2 Indicated by the direction of the arrow.
[0043] like Figure 2 , Figure 3 and Figure 4 As shown, as a possible implementation, first elastic members 122 are respectively provided at both ends of the first connection port 121 , the first elastic member 122 protrudes in the direction toward the metal decorative member 130 , and the first connection member 141 and the second connection member 142 are both connected to the first elastic member 122 .
[0044] Specifically, when the coil 120 and the metal decorative part 130 are arranged adjacent to each other, the first elastic member 122 is arranged at both ends of the first connection port 121, the first elastic member 122 protrudes in the direction toward the metal decorative part 130, and the first connector 141 and the second connector 142 are both connected to the first elastic member 122, so that the coil 120 and the metal decorative part 130 can form a closed conductive loop through the connection between the first elastic member 122 and the first connector 141 and the second connector 142. The first elastic member 122 is made of elastic material, so that the first elastic member 122 arranged at both ends of the first connection port 121 can be closely fitted with the first connector 141 and the second connector 142, respectively, to prevent the first elastic member 122 from being falsely connected with the first connector 141 and the second connector 142. The first elastic member 122 can be connected to the first connector 141 and the second connector 142 by welding, or can be bonded to the first connector 141 and the second connector 142 by a conductive adhesive.
[0045] Compared with the structure in which the first connecting member 141 and the second connecting member 142 are directly welded to the coil 120, the present application arranges the first elastic member 122 at both ends of the first connecting port 121 of the coil 120, so that the first elastic member 122 can fit tightly with the first connecting member 141 and the second connecting member 142, thereby avoiding the phenomenon of virtual connection between the first elastic member 122 and the first connecting member 141 and the second connecting member 142, and improving the connection reliability between the coil 120 and the metal decorative member 130.
[0046] like Figure 2 , Figure 3 and Figure 4 As shown, as a possible implementation, the first connecting member 141 and the second connecting member 142 are welded to the first elastic member 122 .
[0047] Specifically, the first connecting member 141 and the second connecting member 142 are connected to the first elastic member 122 by welding, and the first elastic member 122 is made of a weldable material, so that the first connecting member 141 and the second connecting member 142 are connected to the first elastic member 122 by welding. Compared with other connection methods, the welding process has the characteristics of high reliability, which can effectively reduce the risk of the first connecting member 141 and the second connecting member 142 being separated from the first elastic member 122.
[0048] As a possible implementation manner, the first connector 141 and the second connector 142 are made of metal material; or the first connector 141 and the second connector 142 are made of insulating material, and the first connector 141 and the second connector 142 have metal wires extending in a direction toward the coil 120 .
[0049] Specifically, the first connector 141 and the second connector 142 are conductive. The first connector 141 and the second connector 142 can be made of metal material, so that the first connector 141 and the second connector 142 have high strength while being conductive. The first connector 141 and the second connector 142 can also be made of insulating material, and a metal wire extending in the direction toward the coil 120 is arranged in the insulating material, and the two ends of the metal wire are electrically connected to the metal decorative part 130 and the coil 120 respectively, so that the first connector 141 and the second connector 142 are conductive. Among them, the insulating material can be plastic, and the metal wire can be a laser engraved wiring. The first connector 141 and the second connector 142 made of insulating material can be formed by molds, and the production efficiency is high.
[0050] like Figure 5 , Figure 6 and Figure 7 As shown, as a possible implementation, the metal decoration part 130 is in the shape of a spiral line, the metal decoration part 130 has a plurality of turns, and two ends of the metal decoration part 130 define a second connection port 131 .
[0051] Specifically, the metal decorative part 130 is in the shape of a spiral line, and the two ends of the metal decorative part 130 define a second connection port 131. One end of the metal decorative part 130 is disposed on the housing 110, and the other end is away from the housing 110 in a direction perpendicular to the surface of the housing 110. The number of turns of the metal decorative part 130 is multiple. By configuring the shape of the metal decorative part 130 as a spiral line, the height of the metal decorative part 130 can be further increased, thereby making the metal decorative part 130 closer to the device being sensed. Since the metal decorative part 130 and the coil 120 form a closed conductive loop, the loss of the induction distance between the coil 120 and the device caused by the protrusion of the metal decorative part 130 can be further reduced, thereby improving the induction effect of the coil 120 on the device.
[0052] Furthermore, the magnetic flux of the coil 120 is positively correlated with the induction area. By constructing the metal decorative part 130 as a spiral wire structure with multiple turns, the induction area of the coil 120 can be increased, thereby increasing the magnetic flux of the coil 120 and improving the magnetic induction intensity of the coil 120, thereby improving the sensing ability and card reading ability of the coil 120 with external devices, thereby improving the user's convenience.
[0053] The direction of the current in the closed conductive loop formed by the metal decorative part 130 and the coil 120 is as follows: Figure 5 Indicated by the direction of the arrow.
[0054] like Figure 4 , Figure 7 and Fig.10 As shown, as a possible implementation, the shell assembly 100 further includes: a mainboard bracket 160 installed on the shell 110 , and the coil 120 is installed on the mainboard bracket 160 .
[0055] Specifically, the shell assembly 100 further includes a mainboard bracket 160, which is mounted on the housing 110, and the coil 120 is mounted on the mainboard bracket 160. In this way, the coil 120 can be mounted and fixed by the mainboard bracket 160, so that the coil 120 can be fixed relative to the housing 110, and then the coil 120 and the metal decorative part 130 can be kept in a relatively fixed state, avoiding relative displacement between the coil 120 and the metal decorative part 130, so that the coil 120 and the metal decorative part 130 can be stably connected.
[0056] like Figure 4 , Figure 7 and Fig.10 As shown, as a possible implementation, the cross section of the second connection port 131 is an inclined surface.
[0057] Specifically, the cross section of the second connection port 131 is an inclined surface, that is, the angle between the plane where the cross section of the second connection port 131 is located and the surface of the shell 110 is less than 90°. In this way, obvious gaps can be avoided at the second connection port 131, thereby improving the aesthetics of the shell assembly 100.
[0058] An embodiment of the present application further provides an electronic device, which includes the shell assembly 100 proposed in the first aspect of the present application.
[0059] The electronic device includes any one of a mobile phone, a tablet computer or an e-book.
[0060] like Figure 8 , Fig. 9 and Fig.10 As shown, as a possible embodiment, the electronic device also includes: a circuit board 150, which is installed on the shell 110 of the shell assembly 100; the coil 120 of the shell assembly 100 is surrounded by the peripheral side of the metal decorative part 130 of the shell assembly 100, and the connecting component 140 of the shell assembly 100 includes: a third connecting member 143, which is connected to one end of the second connecting port 131 of the shell assembly 100 and extends in the direction toward the coil 120, and the third connecting member 143 is connected to one end of the first connecting port 121 of the shell assembly 100; a fourth connecting member 144, which is connected to the other end of the second connecting port 131 and extends in the direction toward the circuit board 150, the circuit board 150 is connected to the other end of the first connecting port 121, and the fourth connecting member 144 is connected to the circuit board 150.
[0061] Specifically, as another possible implementation, the coil 120 surrounds the circumference of the metal decorative part 130, and along the direction perpendicular to the surface of the housing 110, the projections of the metal decorative part 130 and the coil 120 on the surface of the housing 110 have an overlapping area. In the case where the coil 120 surrounds the circumference of the metal decorative part 130, the shell assembly 100 further includes a circuit board 150, the circuit board 150 is mounted on the housing 110, and the connecting assembly 140 is connected to the coil 120 through the circuit board 150. The connecting assembly 140 includes a third connecting member 143 and a fourth connecting member 144, wherein the third connecting member 143 is connected to one end of the second port and extends in a direction toward the coil 120, and the third connecting member 143 is connected to one end of the first port. The fourth connecting member 144 is connected to the other end of the second port. The fourth connecting member 144 extends in a direction toward the circuit board 150 and is connected to the circuit board 150. The circuit board 150 is also connected to the other end of the first connecting port 121. Since the circuit board 150 is conductive, the fourth connecting member 144 can be connected to the coil 120 through the circuit board 150.
[0062] Furthermore, the third connector 143 and the fourth connector 144 are both conductive, and the metal decorative part 130 and the coil 120 can be conductively connected through the third connector 143, the fourth connector 144 and the circuit board 150, thereby forming a closed conductive loop together with the metal decorative part 130 and the coil 120.
[0063] By setting a circuit board 150 in the electronic device and connecting the fourth connecting member 144 in the connecting component 140 to the coil 120 through the circuit board 150, on the one hand, the conductive connection between the coil 120 and the metal decorative part 130 is achieved, so that the metal decorative part 130 and the coil 120 form a closed conductive loop together. On the other hand, it can also meet the structural setting of the metal decorative part 130 surrounding the coil 120, so that the metal decorative part 130 can be electrically connected to the coil 120 even when it is surrounded by the circumference of the coil 120.
[0064] like Figure 8 , Fig. 9 and Fig.10 As shown, as a possible implementation, a second elastic member 123 is provided at one end of the first connection port 121 connected to the third connection member 143 , the second elastic member 123 protrudes in a direction toward the metal decorative member 130 , and the third connection member 143 is connected to the second elastic member 123 .
[0065] Specifically, when the coil 120 is wrapped around the circumference of the metal decorative part 130, a second elastic member 123 is provided at one end of the first connection port 121, and the second elastic member 123 is arranged at one end of the first connection port 121 connected to the third connection member 143, and the third connection member 143 is connected to the second elastic member 123, and the second elastic member 123 is conductive, so that the coil 120 and the metal decorative part 130 can be conductively connected through the third connection member 143 and the second elastic member 123. Among them, the second elastic member 123 is made of elastic material, so that the second elastic member 123 and the third connection member 143 can be closely fitted to prevent the second elastic member 123 and the third connection member 143 from being virtual connected. The second elastic member 123 can be connected to the third connection member 143 by welding, or can be bonded to the third connection member 143 by a conductive adhesive.
[0066] Compared with the structure in which the third connecting member 143 is directly welded to the coil 120, the present application sets a second elastic member 123 at one end of the first connecting port 121 of the coil 120, so that the second elastic member 123 and the third connecting member 143 can fit tightly together, avoiding the phenomenon of virtual connection between the second elastic member 123 and the third connecting member 143, thereby improving the connection reliability between the coil 120 and the metal decorative member 130.
[0067] The direction of the current in the closed conductive loop formed by the metal decorative part 130 and the coil 120 is as follows: Figure 8 Indicated by the direction of the arrow.
[0068] like Figure 8 , Fig. 9 and Fig.10 As shown, as a possible implementation, the third connector 143 and the fourth connector 144 are made of metal material; or the third connector 143 and the fourth connector 144 are made of insulating material, the third connector 143 has a metal wire extending in a direction toward the coil 120, and the fourth connector 144 has a metal wire extending in a direction toward the circuit board 150.
[0069] Specifically, the third connector 143 and the fourth connector 144 are conductive. The third connector 143 and the fourth connector 144 can be made of metal material, so that the third connector 143 and the fourth connector 144 have conductivity and high strength. The third connector 143 and the fourth connector 144 can also be made of insulating material, and a metal wire extending in the direction toward the coil 120 or in the direction toward the circuit board 150 is arranged in the insulating material, and the two ends of the metal wire are electrically connected to the metal decorative part 130 and the coil 120 respectively, so that the third connector 143 and the fourth connector 144 are conductive. Among them, the third connector 143 has a metal wire extending in the direction toward the coil 120, and the fourth connector 144 has a metal wire extending in the direction toward the circuit board 150. The insulating material can be plastic, and the metal wire can be a laser engraved wiring. The third connector 143 and the fourth connector 144 made of insulating material can be formed by a mold, and the production efficiency is high.
[0070] As a possible implementation, the electronic device further includes: a camera 170 disposed on the housing 110 , and the metal decoration 130 surrounds the camera 170 .
[0071] Specifically, the electronic device also includes a camera 170, and the camera 170 is disposed on the shell 110. The metal decorative part 130 surrounds the circumference of the camera 170 to enhance the aesthetics of the shell assembly 100 through the metal decorative part 130. Understandably, as the shooting effect of the camera 170 is improved, the space occupied by the camera 170 is increased, which in turn leads to an increase in the space occupied by the metal decorative part 130, and the metal decorative part 130 occupies the installation space of the coil 120. The present application connects the metal decorative part 130 with the coil 120, thereby increasing the induction area of the coil 120 through the metal decorative part 130, increasing the magnetic flux of the coil 120, and enhancing the magnetic induction intensity of the coil 120, thereby enhancing the sensing capability and card reading capability of the coil 120 with external devices, thereby enhancing the user's convenience. Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown in the figure, as a possible implementation, the present application adopts a cascade solution of a metal decorative ring (i.e., metal decorative part 130) and an NFC coil (i.e., coil 120), a gap is opened at a position where the metal decorative ring and the NFC coil are close, and the two ends of the gap are connected to the NFC coil through spot welding springs (i.e., the first elastic part 122 or the second elastic part 123), and the metal decorative ring is connected to the loop of the NFC coil, directly expanding the effective area of the NFC coil. Figure 3 , Figure 6 and Fig. 9As shown, the raised portion of the metal decorative ring is utilized to equivalently raise the Z-direction (i.e., the direction perpendicular to the surface of the housing 110) height of the NFC coil, thereby avoiding the loss of the original NFC coil card reading distance caused by the raised metal decorative ring, and greatly improving the user's reading and writing experience.
[0072] like Figure 2 , Figure 3 and Figure 4 As shown, as a possible implementation, the layout of the metal decorative ring and the NFC coil do not overlap in the Z direction, and an oblique slit (i.e., the second connecting port 131) is made on the metal decorative ring at a position where the metal decorative ring and the NFC coil are close. The oblique cut can prevent obvious breaks from being seen on the appearance surface. Metal bosses or plastic bosses with laser-engraved wiring (i.e., the first connecting member 141 and the second connecting member 142) are made at both ends of the oblique slit toward the direction of the NFC coil, and the outermost circle of the NFC coil is disconnected at the position where the bosses (i.e., the first connecting member 141 and the second connecting member 142) are aligned. Shrapnel pads (i.e., the first elastic member 122) are made on both sides of the disconnection (i.e., the two ends of the first connecting port 121) and are aligned with the bosses. The coil 120 and the metal decorative ring are connected by spot welding shrapnel, and the metal decorative ring is connected to the current loop of the coil 120.
[0073] In this way, the metal decorative ring of the NFC coil and the coil 120 can both obtain the maximum vertical magnetic field area, thereby increasing the magnetic flux of the NFC coil and the induction area of the NFC coil.
[0074] By horizontally cascading the NFC coil and the metal decorative ring, the working area of the NFC coil can cover the upper half of the terminal (i.e., the electronic device). The raised part of the metal decorative ring is used to equivalently raise the Z-direction height of the NFC coil, avoiding the loss of the original NFC coil card reading distance caused by the raised metal decorative ring, making it more convenient for users to use.
[0075] like Figure 5 , Figure 6 and Figure 7 As shown, as a possible implementation, based on the previous implementation, the metal decorative ring is cascaded with the NFC coil, which increases the vertical area of the NFC coil magnetic field, thereby increasing the magnetic flux of the entire NFC coil and improving the card reading and writing performance of the NFC coil.
[0076] In addition, the metal decorative ring is made into a spiral structure (similar to a spring structure) in the Z direction of the shell 110, and the two ends of the metal decorative ring of the spiral structure are connected to the outer ring of the NFC coil by spot welding springs (i.e., the first elastic member 122). This is equivalent to increasing the number of turns of the metal decorative ring part in the conductive loop composed of the NFC coil and the metal decorative ring, and can also increase the magnetic flux of the NFC coil and improve the card reading and writing performance of the NFC coil.
[0077] By horizontally cascading the coil 120 and the metal decorative ring, the NFC coil working area can cover the upper half of the electronic device. At the same time, the spiral metal decorative ring as a radiator can also increase the card reading distance of the NFC coil, making it more convenient for users to use.
[0078] like Figure 8 , Fig. 9 and Fig.10 As shown, as a possible implementation, the NFC coil surrounds the entire metal decorative ring so that the projection areas of the two in the Z direction overlap, and a spot welding spring (i.e., the second elastic member 123) is added at the end of the NFC coil to connect it to one end of the oblique cut (i.e., the second connecting port 131) of the metal decorative ring of the spiral structure, and the end of the metal decorative ring is connected to the PCB (printed circuit board) spring (i.e., the circuit board 150) through a laser engraved trace (i.e., the fourth connecting member 144).
[0079] The NFC coil and the spiral metal decorative ring are cascaded at different Z-direction heights to form a large-size, multi-turn three-dimensional NFC coil loop antenna, which can increase the magnetic flux of the NFC coil. At the same time, the metal decorative ring is used to participate in radiation to increase the Z-direction height of the NFC coil, avoiding the protrusion of the metal decorative ring affecting the card reading and swiping distance of the planar NFC coil.
[0080] The Z-direction cascading of the NFC coil and the spiral metal decorative ring can greatly increase the triggering distance of the NFC coil. At the same time, the NFC coil can directly contact the device or card to work, improving the poor user experience of the flat NFC coil caused by the protrusion of the metal decorative ring. In addition, the NFC coil design needs to wrap the metal decorative ring, which can also increase the card reading area of the NFC coil, greatly improving the convenience of user use.
