Currently, to ensure the reliability of the Type-C port assembly structure, mobile phone designs often separate the Type-C port housing from the overall midframe, creating a floating midframe. This prevents fires caused by static electricity during use of the Type-C port. However, this midframe design can degrade the environment for the phone's antenna, impacting the performance of the antenna surrounding the floating midframe. Utility Model Content

[0041] The technical solutions provided by various embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0042] Figure 1 This is a schematic diagram of the structure of a terminal device according to an exemplary embodiment. Figure 1 ,like Figure 1 As shown, the terminal device 1 provided in the embodiment of the present disclosure may include at least:

[0043] The conductive frame 10 has an opening 101, and the opening 101 is used for the charging port of the terminal device 1 (in Figure 1 (not shown) revealed;

[0044] The conductive middle frame 11 includes a first conductive middle frame 111 and a second conductive middle frame 112, and is located in the space surrounded by the conductive frame 10; the first conductive middle frame 111 is connected to the conductive frame 10 and is spaced apart from the second conductive middle frame 112; the second conductive middle frame 112 is spaced apart from the conductive frame 10 and is used to support the charging port;

[0045] A connector 12 connecting the first conductive middle frame 111 and the second conductive middle frame 112;

[0046] When the conductive frame 10 is reused as an antenna to transmit and receive wireless signals, an induction element is formed between the connector 12 and the first conductive middle frame 111 and between the connector 12 and the second conductive middle frame 112 (in the Figure 1 The induction member is used to ground the first conductive middle frame 111 and the second conductive middle frame 112.

[0047] In the embodiments of the present disclosure, the terminal device may be any electronic device having an antenna; for example, the terminal device may include: a mobile phone, a tablet computer, a smart watch, a personal digital assistant (PDA) or a head-mounted display device (HMD), etc., without limitation.

[0048] Here, the conductive frame can be a component having an opening through which the charging port of the terminal device is exposed; for example, the conductive frame can be a metal frame or a carbon fiber frame. The conductive midframe can be a component used to support the functional components within the terminal device; for example, the conductive midframe can be a metal midframe or a carbon fiber midframe.

[0049] The first conductive middle frame can be the portion of the conductive middle frame that supports other functional components besides the charging port; the second conductive middle frame can be the portion of the conductive middle frame that supports the charging port. The first conductive middle frame can be connected to the conductive frame; the second conductive middle frame can be spaced apart from both the conductive frame and the first conductive middle frame, i.e., the second conductive middle frame can be suspended within the conductive frame.

[0050] For example, if the charging port of the mobile phone is a Type-C port, the second conductive middle frame can be used to carry the Type-C port, and the first conductive middle frame can be a conductive middle frame of the entire device with a gap between the Type-C port and the second conductive middle frame.

[0051] It should be noted that the specific size and shape of the first conductive middle frame and the second conductive middle frame can be set according to the size and shape of the terminal device in the actual application situation, and the specific type of the charging port of the terminal device can also be set according to the actual application situation. The embodiment of the present disclosure is not limited.

[0052] In the embodiment of the present disclosure, the connector may be a component that connects the first conductive middle frame and the second conductive middle frame.

[0053] Here, the connector may be connected between the first conductive middle frame and the second conductive middle frame; or, the connector may connect the first conductive middle frame and the second conductive middle frame and at least partially cover the first conductive middle frame and the second conductive middle frame.

[0054] It is understandable that the antenna in the terminal device can be a frame antenna, that is, the conductive frame of the terminal device is reused as an antenna; or, the conductive frame has an insulating area, and a Laser-Direct-Structuring (LDS) antenna can be set on the insulating area, etc. In the embodiment of the present disclosure, a connector can be provided to connect the first conductive middle frame and the second conductive middle frame, so that when the conductive frame is reused as an antenna to transmit and receive wireless signals, an induction member is formed between the connector and the first conductive middle frame and between the connector and the second conductive middle frame. The first conductive middle frame and the second conductive middle frame arranged at intervals can be grounded through the induction member, so as to effectively solve the efficiency pit problem of the antenna transmitting and receiving wireless signals caused by the suspension of the second conductive middle frame, thereby improving the radiation efficiency of the antenna.

[0055] Here, the connector can be in contact with a display driver integrated circuit (DDIC) disposed on the side of the display screen facing the middle frame. While achieving good heat dissipation of the display screen DDIC, induction elements are formed between the connector and the first conductive middle frame and between the connector and the second conductive middle frame. The first conductive middle frame and the second conductive middle frame, which are spaced apart, are grounded through the induction elements, thereby reducing the impact of the suspension of the second conductive middle frame on the antenna performance.

[0056] The inductive component may include an inductive capacitor or an inductive resistor formed between the connecting component and the first conductive middle frame and between the connecting component and the second conductive middle frame, which is not limited in the embodiment of the present disclosure.

[0057] It should be noted that the specific size and shape of the connector can be set according to the actual application scenario, as long as the connector can connect the first conductive middle frame and the second conductive middle frame, and the embodiment of the present disclosure does not impose any restrictions.

[0058] In addition, the specific type of the connector can also be set according to the actual application scenario, and the embodiment of the present disclosure does not limit it. For example, the connector can include: a rigid connector or a flexible connector.

[0059] In some embodiments, the connector includes a flexible connector. Thus, by providing a flexible connector between the display screen and the conductive midframe of the terminal device, the display screen and the conductive midframe can be effectively connected while better preventing damage to the display screen of the terminal device when dropped, thereby improving the reliability of the terminal device.

[0060] In an embodiment of the present disclosure, the flexible connector is formed of graphite foam or conductive plastic.

[0061] Here, when the flexible connector is formed of graphite foam, the graphite and air filled in the graphite foam can serve as a thermal medium between the display DDIC and the conductive middle frame, better releasing the heat generated by the display DDIC during operation to the conductive middle frame, so as to accelerate heat dissipation through the conductive middle frame and improve the heat dissipation effect of the display DDIC.

[0062] It should be noted that the specific material of the flexible connector can also be set according to the actual application scenario, as long as the flexible connector can provide cushioning and electrical conductivity, and the embodiments of the present disclosure are not limited thereto. For example, the flexible connector may include conductive graphite foam and an insulating film, such as a polyester substrate (PET), coated on the outer surface of the graphite foam.

[0063] In some embodiments, when there is an electric field or a magnetic field between the first conductive middle frame and the second conductive middle frame, an induction member may be formed between the connector and the first conductive middle frame and between the connector and the second conductive middle frame. The induction member may also be used to ground the first conductive middle frame and the second conductive middle frame to prevent the electric field or the magnetic field from affecting the overall grounding of the first conductive middle frame and the second conductive middle frame. When the conductive frame stops being reused as an antenna, the above-mentioned connector may insulate the first conductive middle frame and the second conductive middle frame, that is, the connection between the first conductive middle frame and the second conductive middle frame by the connector is a non-electrical connection, which can meet the fire protection requirements for the second conductive middle frame in the terminal device.

[0064] In the related art, in the design scheme of the Type-C port of the conventional terminal equipment such as mobile phones to meet the electromagnetic compatibility (EMC) fire protection requirements, in order to overcome the deterioration of the mobile phone antenna environment caused by the floating middle frame, it is usually necessary to add a grounding spring on the printed circuit board (PCB) near the Type-C port of the mobile phone to ensure a good electromagnetic environment around the antenna. Figure 2 As shown, three grounding springs 23 are added along the floating edge of the PCB board 22 on the PCB board 22 near the Type-C port 21 of the mobile phone to solve the performance impact of the floating middle frame on the antenna 24 environment at the Type-C port 21.

[0065] It should be noted that in this method of solving the impact of the suspended middle frame on antenna performance by adding a grounding spring, the grounding position of the grounding spring needs to meet specific conditions, which puts higher requirements on the device layout of the PCB board and affects the layout flexibility of other devices on the PCB board.

[0066] Based on this, an embodiment of the present disclosure provides a terminal device, which includes: a conductive frame with an opening, the opening is used to expose the charging port of the terminal device; a conductive middle frame, including a first conductive middle frame and a second conductive middle frame, located in the space surrounded by the conductive frame; the first conductive middle frame is connected to the conductive frame and is spaced apart from the second conductive middle frame; the second conductive middle frame is spaced apart from the conductive frame and is used to carry the charging port; a connector connects the first conductive middle frame and the second conductive middle frame; when the conductive frame is reused as an antenna to transmit and receive wireless signals, an induction member is formed between the connector and the first conductive middle frame and between the connector and the second conductive middle frame, and the induction member is used to ground the first conductive middle frame and the second conductive middle frame through the conductive member. In this way, a connecting piece can be provided to connect the first conductive middle frame and the second conductive middle frame, so that when the conductive frame is reused as an antenna to transmit and receive wireless signals, an induction piece is formed between the connecting piece and the first conductive middle frame and between the connecting piece and the second conductive middle frame. The first conductive middle frame and the second conductive middle frame arranged at intervals can be grounded through the induction piece, thereby effectively reducing the impact of the interval arrangement of the first conductive middle frame and the second conductive middle frame on the antenna performance of the terminal device and improving the radiation efficiency of the antenna of the terminal device; at the same time, by connecting the connecting piece to the first conductive middle frame and the second conductive middle frame, the occupied space between the conductive middle frame and the back shell of the terminal device can be reduced, thereby improving the flexibility of the internal space layout of the terminal device.

[0067] In some embodiments, as Figure 3 and Figure 4 As shown, the inductive component includes at least one first inductive capacitor C1 ; the first inductive capacitor C1 is formed between the connecting component 12 and the first conductive middle frame 111 , and is used to ground the first conductive middle frame 111 .

[0068] In this way, at least one first inductive capacitor can be formed between the connector and the first conductive middle frame, so that the first conductive middle frame can be grounded by utilizing the capacitive effect when the conductive frame is reused as an antenna to transmit and receive wireless signals, thereby reducing the impact of the suspension of the second conductive middle frame on the antenna performance and improving the radiation efficiency of the terminal device antenna.

[0069] In the embodiment of the present disclosure, the connector may at least partially cover the first conductive middle frame. The connector and the first conductive middle frame may be regarded as plates of a capacitor element, that is, at least one first inductive capacitor is formed between the connector and the first conductive middle frame.

[0070] It should be noted that a first inductive capacitor can be formed between one end of the connector and the first conductive middle frame, a first inductive capacitor can be formed between the other end of the connector and the first conductive middle frame, or a first inductive capacitor can be formed between the middle portion of the connector and the first conductive middle frame. This is not limited in the embodiments of the present disclosure.

[0071] Here, when both ends of the connector are covered by the first conductive middle frame and the middle portion of the connector is covered by the second conductive middle frame but not by the first conductive middle frame, the number of first inductive capacitors formed between the connector and the first conductive middle frame may be two. When both ends of the connector are covered by the first conductive middle frame and the middle portion of the connector is covered by the second conductive middle frame and the first conductive middle frame, the number of first inductive capacitors formed between the connector and the first conductive middle frame may be three or four, etc.

[0072] For example, Figure 3 As shown, when one end of the connector 12 covers the first conductive middle frame 111 and the other end of the connector 12 covers the second conductive middle frame 112, the number of the first inductive capacitor C1 formed between the connector 12 and the first conductive middle frame 111 is one; Figure 4 As shown, when both ends of the connector 12 are covered on the first conductive middle frame 111 and the middle portion of the connector 12 is covered on the second conductive middle frame 112, the number of first sensing capacitors C1 formed between the connector 12 and the first conductive middle frame 111 can be multiple, for example, C11 and C12.

[0073] It is understandable that the capacitance values of the first sensing capacitors may be the same or different, and the embodiment of the present disclosure does not limit this.

[0074] It should be noted that the specific number of the first sensing capacitors can be set according to the situation in which the connector covers the first conductive middle frame in the actual application scenario, and the embodiment of the present disclosure does not impose any restrictions. For example, the number of the first sensing capacitors can be 1, 2, or 3.

[0075] In some embodiments, as Figure 3 and Figure 4 As shown, the inductive component further includes at least one second inductive capacitor C2 ; the second inductive capacitor C2 is formed between the connecting component 12 and the second conductive middle frame 112 and is used to ground the second conductive middle frame 112 .

[0076] In this way, at least one second inductive capacitor can be formed between the connector and the second conductive middle frame, so that the second conductive middle frame can be grounded by utilizing the capacitive effect when the conductive frame is reused as an antenna to transmit and receive wireless signals, thereby reducing the impact of the suspension of the second conductive middle frame on the antenna performance and improving the radiation efficiency of the terminal device antenna.

[0077] In the embodiment of the present disclosure, the connector may at least partially cover the second conductive middle frame. The connector and the second conductive middle frame may be regarded as plates of a capacitor element, that is, at least one second inductive capacitor is formed between the connector and the second conductive middle frame.

[0078] It is understandable that the capacitance values of the second sensing capacitors may be the same or different, and the embodiment of the present disclosure does not limit this.

[0079] It should be noted that the specific number of the second sensing capacitors can also be set according to the situation in the actual application scenario where the connector covers the second conductive middle frame, and the embodiment of the present disclosure does not impose any restrictions. For example, the number of the second sensing capacitors can be 1, 2, or 3.

[0080] Similarly, the connector can also span the first and second conductive middle frames, at least partially covering them. In this case, the connector and the first conductive middle frame can be considered the plates of a capacitor element, forming at least one first inductive capacitor between them. The connector and the second conductive middle frame can also be considered the plates of a capacitor element, forming at least one second inductive capacitor between them.

[0081] Here, the capacitance values of the first sensing capacitor and the second sensing capacitor may be the same or different, and may be determined according to the overlapping area between the connector and the first conductive middle frame and the second conductive middle frame in an actual application scenario, and the embodiment of the present disclosure does not impose any limitation thereto.

[0082] For example, when the number of first inductive capacitors formed between the connector and the first conductive middle frame is 2 and the number of second inductive capacitors formed between the connector and the second conductive middle frame is 1, Figure 5 As shown, a first sensing capacitor C11 is formed between one end of the connector 12 and the first conductive middle frame 111, another first sensing capacitor C12 is formed between the other end of the connector 12 and the first conductive middle frame 111, and a second sensing capacitor C2 is formed between the middle portion of the connector 12 and the second conductive middle frame 112.

[0083] In some embodiments, the terminal device may further include:

[0084] A display screen is mounted on a conductive frame;

[0085] A display driver chip is provided on the side of the display screen facing the conductive middle frame;

[0086] The connecting member is attached between the display driver chip and the conductive middle frame and at least partially covers the first conductive middle frame and the second conductive middle frame, and is used to dissipate heat for the display driver chip through the conductive middle frame.

[0087] In this way, the connecting member can be attached between the display driver chip and the conductive middle frame on the side of the display screen facing the conductive middle frame, and at least partially cover the first conductive middle frame and the second conductive middle frame, so that the display driver chip can be dissipated through the conductive middle frame. In this way, while improving the heat dissipation effect of the display driver chip of the display screen, the first conductive middle frame and the second conductive middle frame arranged at intervals can be grounded together through the connecting member to improve the radiation efficiency of the terminal device antenna.

[0088] In the embodiment of the present disclosure, the display driver chip DDIC can be one of the main control elements of the display panel of the display screen. It can send driving signals and data to the display panel through electrical signals to control the brightness and color of the display screen, so that image information such as letters and pictures can be presented on the display screen.

[0089] It is understandable that as the DDIC integration of display screens becomes increasingly higher, power consumption also increases, and high temperatures often occur, leading to degradation of DDIC performance, reduced reliability, and even damage. Therefore, effective heat dissipation is a key factor in ensuring the normal operation of the DDIC and extending its service life. In the disclosed embodiment, a conductive member can be provided between the DDIC and the conductive middle frame, which can not only effectively dissipate heat from the DDIC, but also ground the first and second conductive middle frames spaced apart through the connector, thereby effectively reducing the impact of the spacing between the first and second conductive middle frames on the antenna performance of the terminal device and improving the radiation efficiency of the terminal device antenna.

[0090] It should be noted that the size of the connector must meet the requirements of at least partially covering the first conductive middle frame and the second conductive middle frame, while also being in contact with the display driver chip, so as to release the heat generated by the display driver chip during operation to the conductive middle frame, thereby accelerating heat dissipation through the conductive middle frame and improving the heat dissipation effect of the display driver chip.

[0091] For example, Figure 6 As shown, the terminal device 1 may further include a flexible printed circuit (FPC) 13, which is disposed on the side of the terminal device's display screen facing the conductive middle frame and connected to the display driver chip; the flexible printed circuit 13 may be partially located between the display screen and the connector 12. The FPC may be a connection line between the display screen and the display driver chip, or a connection line between the display screen and functional components on a PCB within the terminal device, such as a central processing unit (CPU).

[0092] In some embodiments, the connector may include:

[0093] Connect the main body;

[0094] The insulating film is coated on the outer surface of the connecting body and is used to insulate the connecting body from the conductive middle frame.

[0095] In this way, an insulating film can be provided on the outer surface of the connecting body of the connector to insulate the connecting body and the conductive middle frame, so that the capacitance effect between the connector and the conductive middle frame can be better utilized to achieve equivalent electrical connection between the first conductive middle frame and the second conductive middle frame, so as to solve the efficiency pit problem of the antenna receiving and transmitting wireless signals caused by the suspension of the second conductive middle frame, and improve the radiation efficiency of the terminal device antenna.

[0096] Here, the connecting body may be the conductive portion of the connector, and the insulating film may be the non-conductive portion of the connector. For example, if the connector is formed of conductive graphite foam, the connecting body may be the graphite foam, and the insulating film may be a PET film covering the outer surface of the graphite foam.

[0097] It should be noted that the specific material of the insulating film can be set according to the actual application scenario, and the embodiments of the present disclosure do not limit it. For example, the material of the insulating film can be silicon oxide, polyester substrate or polyethylene.

[0098] In the embodiment of the present disclosure, the insulating film includes a polyester substrate, thereby improving the reliability and thermal conductivity of the insulating film connected to the outer surface of the body.

[0099] Among them, PET film is a non-conductive material that is durable, strong, tough, moisture-resistant, and resistant to high and low temperatures.

[0100] It can be understood that since both the first conductive middle frame and the second conductive middle frame have conductive properties and the outer surface of the connecting body can be wrapped with a layer of insulating film, the connecting member and the first conductive middle frame, and the connecting member and the second conductive middle frame can be regarded as the plates of the capacitor element, that is, an equivalent capacitor is formed between the connecting member and the first conductive middle frame, and between the connecting member and the second conductive middle frame, so that the capacitive effect of the equivalent capacitor can be better utilized to achieve equivalent electrical connection between the first conductive middle frame and the second conductive middle frame.

[0101] In some embodiments, the terminal device may further include:

[0102] Insulating glue is located between the insulating film and the conductive middle frame and is used to bond the connector and the conductive middle frame.

[0103] In this way, the connecting part and the conductive middle frame can be further insulated by bonding the insulating glue between the connecting part and the conductive middle frame, so that the capacitance effect between the connecting part and the conductive middle frame can be better utilized to achieve equivalent electrical connection between the first conductive middle frame and the second conductive middle frame, so as to solve the efficiency pit problem of the antenna receiving and transmitting wireless signals caused by the suspension of the second conductive middle frame, and improve the radiation efficiency of the terminal device antenna.

[0104] Here, the insulating glue may be a non-conductive glue used to bond the connector and the conductive middle frame; for example, the insulating glue may include but is not limited to polyester insulating glue, epoxy insulating glue, or silicone insulating glue.

[0105] It can be understood that the outer surface of the connecting body of the connector can be wrapped with a layer of insulating film, and the connector wrapped with the insulating film can be covered on the first conductive middle frame and the second conductive middle frame of the conductive middle frame through insulating adhesive, and after the display screen of the terminal device is installed, the connector can achieve heat dissipation contact with the display screen DDIC.

[0106] For example, when the connector is formed of graphite foam, an insulating film such as a PET film can wrap the graphite and air filled therein, that is, the outer surface of the graphite foam is insulated and attached to the first conductive middle frame and the second conductive middle frame of the conductive middle frame by non-conductive glue.

[0107] In the disclosed embodiment, the spacing between the connecting body and the conductive middle frame is less than 0.08 mm. By limiting the spacing between the connecting body and the conductive middle frame, equivalent capacitance can be formed between the connector and the first and second conductive middle frames, paving the way for subsequent equivalent electrical connection between the first and second conductive middle frames using the capacitive effect.

[0108] It should be noted that when an insulating film is provided between the connecting body and the conductive middle frame but no insulating glue is provided, the thickness of the insulating film can be less than 0.08 mm; when an insulating glue is provided between the connecting body and the conductive middle frame but no insulating film is provided, the thickness of the insulating glue can be less than 0.08 mm; when an insulating film and insulating glue are both provided between the connecting body and the conductive middle frame, the combined thickness of the insulating film and the insulating glue can be less than 0.08 mm.

[0109] In related technologies, the floating middle frame and Type-C port shell used in traditional terminal devices such as mobile phones destroy the ground integrity of the antenna at the bottom of the mobile phone; that is, the gap formed by the separation of the Type-C port shell and the floating middle frame cuts off the ground current, forming a high-order mode current distribution, and introducing an efficiency pit within the antenna's operating frequency band.

[0110] like Figure 7As shown in the figure, the dotted line represents the antenna radiation efficiency curve when the terminal device is not equipped with a connector, and the solid line represents the antenna radiation efficiency curve when the terminal device is equipped with a connector. Efficiency dips appear at the antenna radiation frequencies of 2.15 GHz and 2.35 GHz, which are caused by the suspended midframe. This shows that the suspended midframe has a significant impact on the antenna's radiation efficiency.

[0111] In the embodiment of the present disclosure, a connector is provided between the screen of the terminal device and the conductive middle frame to at least partially cover the first conductive middle frame and the second conductive middle frame of the conductive middle frame, so that when the conductive frame is reused as an antenna to transmit and receive wireless signals, an induction member is formed between the connector and the first conductive middle frame and between the connector and the second conductive middle frame. The first conductive middle frame and the second conductive middle frame arranged at intervals can be grounded through the induction member. Figure 7 This effectively solves the antenna radiation efficiency pit caused by the floating midframe, improving the terminal device's antenna radiation efficiency by 2dB to 3dB. Furthermore, because the connector is placed on the side where the conductive midframe and screen meet, it doesn't occupy space on the terminal's bottom PCB. This also differs from related techniques that require the addition of grounding springs to the bottom PCB, improving layout flexibility within the terminal's internal space, such as on the bottom PCB of a phone.

[0112] It should be noted that the “first” and “second” in the embodiments of the present disclosure are only for the convenience of expression and distinction and have no other specific meanings.
