[0056] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure.

Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0057] It should be understood that the terms "include" and "comprising" used in the specification and claims of the present disclosure indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections thereof.

[0058] It should also be understood that the terms used in this disclosure are only for the purpose of describing specific embodiments and are not intended to limit the disclosure. As used in this disclosure and claims, the singular forms of "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise. It should also be further understood that the term "and / or" used in this disclosure and claims refers to any combination of one or more of the associated listed items and all possible combinations, including these combinations.

[0059] As used in this specification and claims, the term "if" may be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" may be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0060] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0061] In mobile device products of related technologies, metal decorative parts generally need to be set at a distance from the antenna assembly to prevent the performance of the antenna assembly from being affected by various metal decorative parts on the surface of the mobile device. In some cases where the antenna assembly is set close to the frame of the mobile device, similar metal decorative parts need to be set at a distance from the frame. In such settings, the metal decorative parts cannot be aligned with the frame of the mobile device, which limits the layout of the mobile device and may prevent the metal decorative parts from being set in an ideal position. If the metal decorative parts are set close to the frame, the reception and transmission of electromagnetic waves by the antenna assembly may be blocked or shielded by the metal decorative parts, resulting in adverse effects on the actual signal. In view of this, the disclosed embodiment provides an antenna module, which can cover the antenna body by setting the position of the first decorative part and the antenna body of the antenna assembly, so that the first decorative part can be coupled by the antenna to produce a specific radiation pattern, thereby improving the antenna performance.

[0062] See also Figure 1 and Figure 2 , Figure 1 shows an exploded schematic diagram of an antenna module of some embodiments of the present disclosure, Figure 2A lateral schematic diagram of the electronic device connection structure of the antenna module of some embodiments of the present disclosure is shown. In some embodiments, the antenna module is arranged in a mobile device with a camera assembly to send and receive electric signals, wherein the antenna module 100 may include an electrostatic protection assembly and a first antenna assembly 30 arranged inside the mobile device. The first antenna assembly 30 may include a first antenna body 37, and the first antenna assembly 30 is electrically connected to the mainboard assembly 10 in the mobile device. The first antenna assembly 30 may also include a rear assembly 50, which also includes a first decorative member 40 at least partially covering the outside of the camera assembly, wherein the first decorative member 40 may include a coupling portion, which is formed of a conductive material such as metal and is electrically connected to the electrostatic protection assembly, and the coupling portion of the first decorative member 40 covers the antenna body 37 of the first antenna assembly 30. The bottom of the first decorative member 40 and the top of the first antenna body 37 are the closest parts between the two, and here, the distance a between the two satisfies: a is less than or equal to 0.1λ. That is, the distance a between the bottom of the first decorative member 40 and the top of the first antenna body 37 is less than or equal to one tenth of the wavelength λ of the electromagnetic wave in the working frequency band of the antenna assembly; or, a is less than 0.05λ. That is, the distance a between the bottom of the first decorative member 40 and the top of the first antenna body 37 is less than one twentieth of the wavelength λ of the electromagnetic wave in the working frequency band of the antenna assembly.

[0063] In some embodiments, the antenna module 100 may include a front component 20, a mainboard component 10, a mainboard support 31, and a rear component 50, which are closely arranged from front to back. Among them, the mainboard component 10 may include an electrostatic protection component and a camera component 14. The first antenna component 30 is used to be electrically connected to the mainboard component 10, and the first antenna component 30 also includes a first antenna body 37 for transmitting and receiving electromagnetic waves, and the first antenna body 37 can be formed in a sheet shape, for example. The rear component 50 may include, for example, a back cover 51, and a first decorative member 40 fixedly arranged on the outer surface of the back cover 51 and covering the outer side of the camera component 14 on the mainboard. The first decorative member 40 may include a plate-shaped main body, and is formed of a conductive material such as metal. The main body of the first decorative piece 40 can also cover the first antenna body 37 in a direction perpendicular to the plate surface of the first decorative piece 40, so that its plate surface is arranged parallel to the sheet-shaped first antenna body 37, and the closest distance a between the two is less than one twentieth of the wavelength λ of the electromagnetic wave in the working frequency band of the antenna component, so that the main body of the first decorative piece 40 can act as a coupling part to resonate with the first antenna body 37, thereby improving the antenna performance.

[0064] Specifically, in some embodiments, the front component 20 may include, for example, a display component for displaying an interactive interface, a middle frame for enhancing structural strength, etc. The mainboard component 10 may be, for example, a PCB component, which may include, for example, a substrate for arranging electronic devices, electronic devices arranged on the substrate, a camera component 14 for video recording, and a battery, etc. The electronic devices may include, for example, an electric control component for controlling the camera component 14 and the display component, etc., and an electrostatic protection component for protecting other electronic devices. Among them, the rear component 50 may include a rear cover 51, which may include a rear cover plate that is generally in the shape of a plate, and a rear cover edge 511 extending from the circumferential outer side of the rear cover plate toward the front component 20. The rear cover edge 511 may form a shape match with the outer peripheral side edge of the front component 20, so that the rear cover 51 can be buckled on the front component 20, so that the rear component 50 and the front component 20 define a storage space inside, and the aforementioned mainboard component 10 and the first antenna component 30 can be accommodated inside the storage space.

[0065] In the layout design of the mobile terminal of the related design, it is common to arrange the antenna assembly at the frame position of the mobile terminal. In the previous design, if the first decorative element is arranged to be aligned with the frame, it is possible that the first decorative element will affect the performance of the antenna assembly. However, according to the arrangement described in the above embodiment, when the first decorative element 40 is arranged to be aligned with the frame, it will not only not affect the performance of the first antenna assembly 30 arranged at the frame, but also can be further optimized by means of the coupling of the coupling part of the first decorative element 40 with the first antenna body 37. For example, in some embodiments, the first antenna body 37 of the first antenna assembly 30 can be arranged close to a corner of the frame 511. At the same time, the first decorative element 40 is also close to the corner, and its edge is aligned with the corner. Or the distance b between the edge of the coupling part of the first decorative element and the edge of the frame 511 satisfies: b<0.05λ, that is, the distance b between the edge of the first decorative element 40 and the edge of the frame 511 is less than one twentieth of the wavelength λ of the electromagnetic wave in the working frequency band of the first antenna assembly 30.

[0066] The camera assembly 14 may further include a main camera assembly 15 and a secondary camera assembly 17. The camera assembly 14 may be arranged on the mainboard assembly 10 on a side away from the front assembly 20, so that the lens of the camera assembly 14 is arranged toward the rear assembly 50. The rear assembly 50 may further include a first decorative member 40 for protecting and decorating the lens assembly. A lens opening 513 for exposing the lens of the camera assembly 14 may be provided on the rear cover 51, and the first decorative member 40 is provided outside the lens opening 513, so that the first decorative member 40 can at least partially cover the portion of the camera assembly 14 other than the lens. In addition, the main body of the first decorative member 40 covers the first antenna body 37 of the first antenna assembly 30 in a direction perpendicular to the plate surface of the first decorative member 40, so that the first decorative member 40 can be coupled by the first antenna body 37 to produce a specific radiation pattern, thereby improving the antenna performance.

[0067] In some embodiments, the front component 20, the mainboard component 10, the mainboard support 31 and the rear component 50 of the antenna module can be roughly formed into a plate shape. The first antenna component 30 is fixedly connected to the mainboard support 31 and can be arranged on the side of the mainboard support 31 away from the front component 20. The first antenna component 30 may include an antenna bracket 39 and a first antenna body 37, wherein one end of the antenna bracket 39 is fixedly connected to the mainboard support 31, and the other end is fixedly connected to the first antenna body 37, so as to fix the first antenna body 37 relative to the mainboard support 31. The mainboard support 31 is provided with a camera hole for exposing the lens of the camera assembly 14, one side of the camera hole is aligned with the camera of the camera assembly 14, and the other side is aligned with the lens opening 513 on the back cover 51, so that the lens of the camera assembly 14 can be directly exposed through the mainboard support 31 and the back cover 51.

[0068] See also Figure 2 In some embodiments, the mainboard component 10 includes an RF feeding component 19 and an antenna matching component 18 disposed on the substrate, wherein the RF feeding component 19 can be electrically connected to the first antenna component 30 through a metal trace to feed a signal and tune the first antenna body 37, and the antenna matching component 18 can be electrically connected to the first antenna component 30 through a metal trace to tune the first antenna body 37. Figure 3 A schematic diagram of the circuit composition of a radio frequency feeding assembly 19 of some embodiments of the present disclosure is shown. The radio frequency feeding assembly 19 may include an antenna matching network, a radio frequency circuit, and a radio frequency chip connected in series.

[0069] In some embodiments, the first decorative member 40 may also be provided with one or more tuning parts extending in a direction perpendicular to the plate surface of the first decorative member 40 toward the front component 20. The tuning part may be, for example, in the shape of a long strip, and is used to pass through the mainboard support 31 and electrically connect to the electronic device on the mainboard component 10. For example, a decorative member matching component may also be provided on the mainboard, and a first tuning part of the first decorative member 40 extending toward the mainboard component 10 may be used to be electrically connected to the decorative member matching component. The decorative member matching component may, for example, be a topological network component composed of a capacitor and / or a resistor and / or an inductor provided on a printed circuit board, which may be used to adjust the electrical length and resonant frequency of the first decorative member 40 after being electrically connected to the first tuning part of the first decorative member 40. In addition, an electrostatic protection component 16 may also be provided on the mainboard, and the electrostatic protection component 16 may be electrically connected to a second tuning part 43 of the first decorative member 40 through a metal trace, so as to discharge the static electricity on the first decorative member 40.

[0070] It will be understood by those skilled in the art that Figure 3 The connection structure shown in the figure is only used to exemplify the connection relationship between some electronic components in the antenna module of some embodiments of the present disclosure, and is not used to limit the actual connection structure of the antenna module. For example, the positions of the antenna matching component 18 and the RF feeding component 19 can be interchanged, and the positions of the decorative component matching component and the electrostatic protection component 16 can also be interchanged. In addition, see Figure 4 , Figure 4 The schematic diagram of the circuit composition of the electrostatic protection component 16 of some embodiments of the present disclosure is shown. The electrostatic protection component 16 includes a decorative matching component and an electrostatic protection device, and the electrostatic protection device is connected to the ground in front of the decorative matching component, so that the electrostatic protection component has both an electrostatic protection function and can be used as a matching component of the first decorative component 40 to adjust its electrical length and resonant frequency. The electrostatic protection device can be a TVS tube, a large inductance and high current resistance inductor, etc. In some embodiments, the metal traces provided on the mainboard or the first antenna component 30 for electrical connection with other electronic devices can be a conductive spring mechanism, or a metal probe, etc.

[0071] In some embodiments, the first tuning portion 41 and the second tuning portion 43 extending from the first decorative element 40 can be configured to be electrically connected to a corresponding decorative element matching component (for example, in this case Figure 2 16 and 17 correspond to two decorative part matching components respectively). Specifically, the first tuning part 41 can be electrically connected to a first matching component, and the second tuning part 43 can be electrically connected to a second matching component, thereby, the electrical length and the resonant frequency on the first decorative part can be adjusted jointly by the two matching components respectively.

[0072] In addition, refer to Figure 7 , Figure 7 A rear view schematic diagram of the antenna module of some embodiments of the present disclosure is shown, in which the antenna bracket 39, the back cover 51, the camera and other components are hidden for the convenience of showing the specific structure. In some embodiments, when the first antenna body 37 of the first antenna assembly is arranged to overlap with the central part of the longitudinal direction of the first decorative member. The first tuning portion 41 and the second tuning portion 43 can be arranged asymmetrically with respect to the transverse center line of the first decorative member 40. For example, the first tuning portion 41 can be arranged to be located on the transverse center line of the first decorative member 40, and the second tuning portion 43 can be arranged near a distal end of the first decorative member 40 in the vertical direction relative to the transverse center line. The reason for this arrangement is that when the first decorative member covers the first antenna body 37 and generates internal current under the influence of the first antenna body 37, the distribution of the internal current on the first decorative member 40 will be roughly symmetrical about the transverse center line. At this time, if the first tuning part 41 and the second tuning part 43 and the corresponding first matching component and the second matching component are arranged in a symmetrical manner about the transverse center line, the adjustment effects of the two matching components on their respective corresponding adjustment parts will be roughly equal. If the adjustment parts corresponding to the two matching components are set to be asymmetrical about the transverse center line, the two matching components can produce different adjustment effects on the first decorative member according to the change of the adjustment position. In this way, the first matching component and the second matching component can be used to achieve large-range and small-range adjustment respectively, thereby achieving precise adjustment and improving the accuracy of the antenna tuning process.

[0073] The following describes some embodiments of the antenna enhancement mechanism according to the present disclosure by combining S parameter characteristic diagrams and system total efficiency characteristic diagrams generated based on different antenna enhancement mechanism solutions. Figure 5a and Figure 5b , Figure 5a A schematic diagram showing S parameter characteristics of an antenna module with and without the first decorative element 40 installed according to some embodiments of the present disclosure is shown; Figure 5b A schematic diagram of the overall system efficiency characteristics of an antenna module with or without the first decorative element 40 installed according to some embodiments of the present disclosure is shown. Figure 5a It can be seen that, compared with the antenna module without the first decorative member 40, the antenna module with the first decorative member 40 has an additional resonance, and the impedance bandwidth is greatly increased. Figure 5b It can be seen that compared with the antenna module without the first decorative part 40 installed, the efficiency peak of the antenna module with the first decorative part 40 installed is increased by 1dB from -3.76dB to -2.8dB, and the -6dB efficiency bandwidth is increased by 200MHz from 330MHz to 530MHz.

[0074] In addition, refer to Figure 6aand Figure 6b , Figure 6a A schematic diagram showing current distribution of an antenna module equipped with a first decorative member 40 according to some embodiments of the present disclosure when the operating frequency is 2.4 GHz; Figure 6b FIG. 4 is a schematic diagram showing the current distribution of an antenna module with a first decorative element 40 installed at an operating frequency of 2.4 GHz according to some embodiments of the present disclosure. Figure 6a It can be seen that when the operating frequency is 2.4 GHz, the current is mainly concentrated on the first antenna body 37. Figure 6b It can be seen that when the operating frequency is 2.8 GHz, the current is not only distributed on the first antenna body 37, but also concentrated on the first decorative part 40, and presents a 1 / 2λ dipole mode, where λ is the wavelength of the electromagnetic wave at the operating frequency, and the current direction on the first decorative part 40 is opposite to the current direction on the first antenna body 37.

[0075] See also Figure 7 In some embodiments, the antenna module may further include a second decorative member 60, which may be, for example, a metal decorative screw. And it may further include a second antenna assembly 70. The second antenna assembly 70 includes a second antenna body 71 that is roughly sheet-shaped. The second antenna body 71 is arranged close to the first decorative member 40, and the first decorative member 40 also has a side wall 401 extending perpendicular to its plate surface direction, and the projection of the side wall 401 in the direction toward the second antenna body 71 can cover the second antenna body 71, so as to be used as a coupling part to couple with the second antenna body 71 and generate resonance. In some embodiments, the second antenna assembly 70 approaches the first decorative member 40 only from a lateral direction, but does not overlap with the first decorative member 40 in a direction perpendicular to its plate surface. The decorative screw is arranged to be close to the first decorative member 40 and the second antenna body 71 at the same time, but the decorative screw is not directly connected to the antenna radiator. The distance between the second antenna body 71 of the second antenna assembly 70 and the first decorative member 40 and the second decorative member 60 is less than or equal to one twentieth of the wavelength of the electromagnetic wave of the working frequency of the second antenna assembly 70. Thus, the second antenna body 71 can be coupled with both the first decorative member 40 and the second decorative member 60, thereby further optimizing the performance of the antenna module.

[0076] In some embodiments, the second antenna body 71 further includes a substantially L-shaped bending portion 73, the bending portion 73 includes three substantially U-shaped side portions, wherein two adjacent side portions are perpendicular to each other, one side portion of the bending portion 73 is close to the first decorative member 40, and the other side portion is close to the second decorative member 60, and the corner of the U-shaped structure of the bending portion 73 is close to the side wall of the first decorative member 40. The bending portion 73 is close to the two decorative members through the two side portions, thereby improving the coupling effect with the two decorative members. At the same time, the bending portion 73 also provides a sharper corner for the current path, so that the current will suddenly turn when flowing through the corner of the bending portion 73, and this turning will increase the radiation of electromagnetic waves, thereby further improving the coupling effect with the adjacent decorative members.

[0077] In this embodiment, the first decorative component 40 can still be electrically connected to the decorative component matching component and the electrostatic protection component 16 on the mainboard component 10 through the tuning part. The RF feeding component 19 is electrically connected to the first antenna component 30 and the second antenna component 70 to feed the RF signal to the first antenna body 37 and the second antenna body 71. At the same time, the antenna matching network is electrically connected to the first antenna body 37 and the second antenna body 71 to tune the antenna.

[0078] See also Figure 8a and Figure 8b , Figure 8a A schematic diagram showing S parameter characteristics of antenna modules respectively provided with three types of decorative elements according to some embodiments of the present disclosure is shown; Figure 8b A schematic diagram of the system total efficiency characteristics of antenna modules using three types of decorative parts settings according to some embodiments of the present disclosure is shown; the three settings are respectively an antenna module installed with a first decorative part 40 and a second decorative part 60, an antenna module not installed with the first decorative part 40 and the second decorative part 60, and an antenna module only installed with the first decorative part 40.

[0079] Depend on Figure 8a It can be seen that compared with the antenna module without the first decorative member 40 and the second decorative member 60, the S11 curve of the antenna module with only the first decorative member 40 is optimized from about -2.5dB to about -6dB at the deepest point, and the impedance is also significantly optimized; and for the antenna module with both the first decorative member 40 and the second decorative member 60, the second decorative member 60 will add a resonance to the antenna, and the impedance bandwidth is significantly increased. Figure 8bIt can be seen that compared with the antenna module without the first decorative member 40 and the second decorative member 60, the antenna efficiency of the antenna module with only the first decorative member 40 is increased by 4dB from -7.2dB to -3.2dB. For the antenna module with both the first decorative member 40 and the second decorative member 60, the second decorative member 60 will greatly increase the antenna working bandwidth, and the -7dB efficiency bandwidth is increased by 300MHz from 405MHz to about 700MHz. See also Fig. 9 , Fig. 9 FIG. 4 shows a schematic diagram of current distribution of an antenna module provided with a first decorative element 40 and a second decorative element 60 according to some embodiments of the present disclosure. Fig. 9 It can be seen that when the frequency is 3.4 GHz, current is distributed not only on the first antenna body 37 , but also on the first decorative member 40 and the second decorative member 60 .

[0080] In some embodiments, the first antenna assembly 30 can be used for the transceiver of electromagnetic waves in the medium and high frequency bands, for example, it can be used for the transceiver of electromagnetic waves in the WiFi 2.4G band, so as to communicate with the current mainstream wireless routers and other communication devices. When designing the operating frequency, the distance a between the bottom of the first decorative member 40 and the top of the first antenna body 37 should satisfy: a is less than or equal to 0.1λ, or a is less than 0.05λ. The operating frequency corresponding to the WiFi 2.4G band is 2.4GHz, then λ=125mm, then the distance a between the bottom of the first decorative member 40 and the top of the first antenna body 37 should be less than 6.25mm. In other embodiments, the first antenna assembly 30 can be used for the transceiver of electromagnetic waves in the N77 band, so as to communicate with the current mainstream 5G network equipment. At this time, the distance a between the bottom of the first decorative member 40 and the top of the first antenna body 37 should satisfy: a is less than 0.05λ. The operating frequency corresponding to the N77 frequency band is 3.3 GHz to 4.2 GHz, and at this time λ is approximately 71 mm to 90 mm, so the distance a between the bottom of the first decorative piece 40 and the top of the first antenna body 37 should be less than 3.5 mm.

[0081] At the same time, the second antenna assembly 70 can be used for transmitting and receiving electromagnetic waves in other frequency bands different from the first antenna assembly 30, and the distance between the second antenna body 71 and the first decorative member 40 and / or the second decorative member 60 is determined according to the actual frequency band used. It can be understood by those skilled in the art that the present disclosure does not impose specific restrictions on the operating frequency of the first antenna assembly 30 and the second antenna assembly 70, which can also be, for example, WiFi5G, GPS, B1 / N1, B2 / N2, B3 / N3 frequency bands, etc.

[0082] According to the following Figures 10 to 33 Further description is made of multiple specific embodiments of multiple antenna modules with antenna adjustment parts applied to mobile terminals. Among them, each embodiment is provided with a first antenna component and a metal coupling part included in some embodiments of the present disclosure as described above, and the metal coupling part is spaced apart from the first antenna body, and the minimum distance a between the first decorative part and the first antenna body and the wavelength λ of the electromagnetic wave in the working frequency band of the first antenna component satisfy: a≤0.1λ, and the metal coupling part at least partially covers the antenna body in the direction toward the middle frame of the mobile terminal. In addition, in some embodiments, a second decorative part 409 is also provided. The second decorative part 409 can be a decorative screw provided adjacent to the first decorative part. For example, it can be based on Fig.10 The two decorative screws arranged adjacent to the first decorative piece, or one of the two decorative screws, are arranged adjacent to the second antenna assembly, and the distance between the second antenna body of the second antenna assembly and the first decorative piece and the second decorative piece 409 is less than or equal to one twentieth of the wavelength of the electromagnetic wave of the working frequency of the second antenna assembly.

[0083] The disclosed embodiment provides a mobile terminal, which, by providing a first support member protruding from the back panel on the back panel of the terminal and a second support member also protruding from the back panel and being detachable, can prevent the back panel surface from being placed on a plane when the back cover is in use. The plurality of support members can form a support surface different from the back cover body, thereby allowing the back cover body to be suspended in the plane, thereby preventing the back cover from being damaged by friction, bumps, and the like due to contact with the plane.

[0084] See also Fig.10 and Fig.11 , Fig.10 A three-dimensional schematic diagram of a mobile terminal according to some embodiments of the present disclosure is shown. Fig.11 A side view schematic diagram of a mobile terminal of some embodiments of the present disclosure is shown. In some embodiments, the mobile terminal may include a terminal body and a terminal back panel fixed to the terminal body. The terminal back panel may be, for example, roughly rectangular, and a first support member is provided at its first corner, and the first support member protrudes from the terminal back panel in a direction perpendicular to the plate surface of the terminal back panel for supporting the terminal body relative to a placement plane. At the same time, a second support member is also provided on the terminal back panel, and the second support member is detachably arranged relative to the terminal back panel, and it also protrudes perpendicularly to the plane of the terminal back panel for supporting the terminal body. By using the first support member and the second support member protruding perpendicularly to the terminal back panel, when the terminal is placed on a placement plane such as a desktop, the terminal back panel will be separated from the placement plane by the support barrier of the first support member and the second support member, thereby avoiding being scratched and rubbed, resulting in scratches or wear.

[0085] Specifically, in some embodiments, the terminal may include a camera assembly disposed at a first corner of its rectangular terminal back plate. It will be appreciated by those skilled in the art that, due to factors such as lens combination or focal length requirements, the camera assembly often has a large thickness, which makes it difficult to avoid protruding from the back of the terminal back plate. In some embodiments, the camera assembly of the terminal includes a first camera assembly and a second camera assembly, the first camera assembly may, for example, include a main lens and related components thereof, and the second camera assembly may, for example, include other camera-related components such as a secondary lens and / or a flash. The first camera assembly and the second camera assembly are arranged at intervals from each other. At the same time, the first support member may include two protrusions, i.e., two support rings protruding perpendicular to the plane of the terminal back plate. The first support ring may surround the outer periphery of the protruding portion of the first camera assembly, while the second support ring surrounds the outer periphery of the protruding portion of the second camera assembly, and the top of the protruding portion of the first support ring and the second support ring exceeds the height of the first camera assembly and the second camera assembly along the vertical direction of the terminal back plate. At the same time, the second support member is arranged on the second corner of the terminal back panel opposite to the first corner, where the term "relative" means that the second corner is diagonally opposite to the first corner. The first support member may include, for example, an outer edge shape that is the same as or similar to the shape of the first corner of the terminal back panel, and the second support member may also include, for example, an outer edge shape that is the same as or similar to the shape of the second corner of the terminal back panel, so as to align with the outer periphery of the terminal back panel to avoid the formation of steps and other structures that are easy to accumulate dirt. However, the present disclosure does not limit the specific shapes of the first support member and the second support member, and they can be formed into other shapes according to actual application conditions.

[0086] When the terminal back plate is placed downward on a placement plane such as a desktop, the first support ring and the second support ring are beyond the first camera assembly and the second camera assembly in a direction perpendicular to the terminal back plate plane, so they can replace the first camera assembly and the second camera assembly to contact the placement plane, so that the lens or related exposed optical device parts will not directly contact the placement plane. In addition, when the terminal back plate is placed downward, the second support member also contacts the placement plane, so that it can form a three-point support structure with the first support ring and the second support ring. And because it and the first support ring and the second support ring are respectively arranged at the first and second corners opposite to each other, when the terminal is placed flat, the center of gravity of the terminal body must fall within the triangular support area formed by the three points in a direction perpendicular to the back plate surface. Therefore, when the terminal is placed flat, it can be ensured that it will not deflect due to its own weight, resulting in the situation where the terminal back plate or the side of the terminal back plate contacts the placement plane. In addition, in some embodiments, the distal ends of the first support ring and the second support ring protruding from the plane of the terminal backplane can be flush with the distal end of the second support member protruding from the plane of the terminal backplane, so that when the terminal backplane is placed downward, in the three-point support structure formed by the first support ring, the second support ring, and the distal end of the second support member, the planes at the top ends corresponding to the three can all contact the placement plane as a whole, thereby increasing the contact area to distribute the terminal's own weight and the impact force of picking and placing, making the contact parts of the three with the placement plane less prone to wear. At the same time, the three contact surfaces also make the placement of the terminal more stable, and it will not easily flip and tilt. In addition, in some embodiments, there can also be a certain height difference between the three contact surfaces, for example, the height difference perpendicular to the direction of the terminal backplane is .mm, so that the structural selection of the first support member and the second support member has a higher degree of freedom.

[0087] The common lens assembly currently often includes an outer surface made of sapphire glass. By setting a support ring protruding perpendicular to the surface of the terminal back plate, the surface of the lens assembly inside the decorative ring will not be scratched even if the terminal is placed on any plane. In addition, the support ring not only protects the surface of the lens assembly inside it from contacting the placement plane, but also prevents the entire first support member and other surfaces of the terminal back plate near the first corner from being scratched.

[0088] In this way, even when using materials such as plastic and leather whose wear resistance is generally lower than that of metal, scratches and bumps can be avoided in some scenarios, thereby extending the appearance and service life of the back cover.

[0089] It can be understood by those skilled in the art that in the embodiment where the first support ring and the second support ring are in contact with the placement plane, the weight of the terminal and the collision impact force generated when placing and taking the terminal will be concentrated on the contact surface between the support ring and the desktop. Therefore, in order to avoid damage to the support ring during frequent friction contact with the desktop, the support ring or the top portion of the support ring can be made of a hard and friction-resistant material, and the wear resistance and impact resistance of the support ring or the contact portion can be further improved by a corresponding surface treatment process. For example, in some embodiments, the first support ring and the second support ring can be made of stainless steel as the main material, and their surfaces can be treated with a DLC (Diamond-like Carbon) process to make their surface hardness reach HV and greatly improve their wear resistance.

[0090] See also Fig.12 and Fig.13 , Fig.12 A three-dimensional schematic diagram showing a second supporting member of a mobile terminal according to some embodiments of the present disclosure is shown. Fig.13 A three-dimensional schematic diagram of a mobile terminal of some embodiments of the present disclosure when the second support member is removed is shown. The second support member includes a connecting portion and a supporting portion 220. The connecting portion may be, for example, a connecting member such as a stud for connecting to a terminal backplane, and the supporting portion may be, for example, fixedly connected to one end of the connecting portion. In some embodiments, the connecting portion is a stud, and the supporting portion may be roughly cylindrical, and the supporting portion and the stud are coaxially arranged and fixedly connected relative to each other. In some embodiments, the supporting portion and the stud may be formed in an integrally formed manner, for example, a cylindrical supporting portion may be formed by molding on one side of a nut with a cap bolt. By arranging the supporting portion and the connecting portion formed as a stud to be coaxially fixedly connected, the circumferential side surface of the cylindrical supporting portion may facilitate the user to perform a screwing operation, and the enlarged radius also enlarges the rotational torque acting on the connecting portion, thereby making the second support member more convenient to install and remove. Further, in some embodiments, anti-slip lines may be added to the circumferential side surface of the roughly cylindrical supporting portion to further facilitate the user to install and remove. In addition, a positioning recess may be formed on the axial end surface of the support portion facing the terminal back plate, and the positioning recess is used to cooperate with a positioning protrusion formed on the terminal back plate to position the second support member when installing the second support member.

[0091] It is understood by those skilled in the art that, although some embodiments in which the connecting portion is set as a bolt are described above, the present disclosure does not limit the specific connection method between the second support member and the terminal backplane. For example, the connecting portion of the second support member can be a magnetic member such as a magnet, and by setting a corresponding magnetic adsorption member and a positioning groove at the corresponding position of the terminal backplane, it can be adsorbed in the positioning groove by magnetic attraction. At the same time, in some embodiments, a second support member with a variety of different shapes or functions can be provided, and each second support member can be configured with a corresponding magnetic member, and the terminal can identify different accessories by connecting with the different magnetic members. For example, in some embodiments, the connecting portion of the second support member can be provided with a plug-in, and the plug-in can be matched with the corresponding positioning groove on the terminal backplane in a shape-matching manner. It is understood by those skilled in the art that, for example, by setting the second support member with various functions as a connecting portion with various connection types, the terminal can also be set to identify different accessories by its connection method with the corresponding second support member, and under the control of the corresponding identification control module in the terminal, the terminal can make a corresponding response after connecting with the second support member. For example, when the second support including the aromatherapy box is detected, the time can be recorded with the start of the connection as the starting point, such as the queen reminds that the fragrance in the aromatherapy box is used up and needs to be replenished, the fragrance tablets need to be replaced, etc. Alternatively, the identification control module of the terminal can match the colors and types of different accessories on the second support to make the UI into different color styles / themes.

[0092] In some embodiments, a positioning groove may be further provided on the terminal back panel of the mobile terminal, and the positioning groove may be provided, for example, around the installation position of the second support member on the terminal back panel, for positioning the second support member after the second support member is installed. The positioning groove may be roughly circular, or may be formed into other shapes, as long as there is enough space in the middle for installing and rotating the second support member. A connecting mechanism corresponding to the connecting portion is provided in the center thereof. For example, when the connecting portion is a stud, the connecting mechanism may be a corresponding threaded hole. In some embodiments, the terminal body may also include a connecting and fixing portion corresponding to the connecting mechanism, so that the connecting portion of the second support member can be further fixedly connected with the connecting and fixing portion, thereby being directly fixed to the terminal body. Through this arrangement, the positioning of the second support member is achieved without adding additional screws or other fixing structures. For example, when the terminal back panel is thin or the weight of the second support member is large, the connecting and fixing portion can prevent the second support member from falling off or even damaging the terminal back panel due to insufficient fixing force of the connecting mechanism. Alternatively, the connecting mechanism may also include a portion extending into the terminal body in a direction perpendicular to the surface of the terminal back panel, which provides an additional fixing area for the connecting portion of the second support member, thereby improving the fixing force. Those skilled in the art will appreciate that, in some other embodiments, the positioning groove may not be provided, and a connecting mechanism may be directly provided on the surface of the terminal back panel so that the second support member can be directly fixedly connected to the terminal back panel.

[0093] In some embodiments, the portion of the bolt of the connection part adjacent to the end surface of the support part may be provided with a metal bevel, and at the same time, a corresponding bevel is also provided at the entrance of the screw hole on the back plate of the terminal, so that when the user tightens the stud, when the bevels fit each other, the support force between the metals makes it difficult to continue tightening, so that the surface of the mobile phone back cover and the support part will not be scratched due to over-tightening, especially when the surface opposite to the back cover or the support part is a plastic part, excessive deformation and damage caused by contact between the two is avoided. This avoids further screwing in, prevents the back cover or the support part from being damaged due to excessive screwing force, and further avoids thread damage.

[0094] The entire positioning groove can be recessed by the surface of the terminal backplane, so that the positioning groove can at least partially accommodate the second support member in a direction perpendicular to the plane of the terminal backplane. By at least partially accommodating the second support member, on the one hand, the probability of the outer peripheral part of the second support member accidentally touching other obstacles and causing scratches can be reduced, and on the other hand, the thickness of the second support member perpendicular to the terminal backplane can be ensured to ensure its structural strength. In addition, by partially accommodating the second support member, the risk of accidentally releasing the connection with the terminal backplane due to rotation caused by friction on the circumferential side surface can also be reduced. In addition, the positioning groove can be at least partially connected to the outside of the terminal backplane in a direction parallel to the terminal backplane. For example, a fracture can be provided at least in part of its circumferential side wall, so that the second support member accommodated therein can be exposed by the fracture in a direction parallel to the surface of the terminal backplane. In the case where the first support member includes a connector formed as a stud, the exposed portion of the second support member allows the user to approach the side of the first support member and perform installation or removal operations on it.

[0095] In some embodiments, the support portion of the first support member can be made of a transparent or translucent material in whole or in part, and the support portion of the transparent or translucent material allows the user to easily observe the situation inside the positioning groove. For example, when there is a foreign object in the positioning groove or on the bottom side of the second support member, if the foreign object cannot be detected in time and the second support member is directly installed, it may cause scratches or even jamming and damage to the corresponding part of the second support member or the terminal back panel. In addition, setting the support portion of the second support member to a transparent material can also visually reduce the thickness of the second support member and improve the aesthetics. In some embodiments, the support portion can be configured to include a transparent upper half and a non-transparent lower half, wherein the height of the non-transparent portion of the bottom surface is flush with the surface of the terminal back panel, which not only ensures the operability of the second support member, but also ensures the consistency of appearance.

[0096] It will be understood by those skilled in the art that, although some embodiments of the first support member disclosed above include two protrusions, the first support member may also be configured to have a single protrusion, provided that the distal ends of the first support member and the second support member protruding in a direction perpendicular to the plane of the terminal back panel are in the same plane. For example, the first support member may protrude as a whole, surround the camera assembly at the periphery thereof, and exceed the height of the camera assembly at the top of its protrusion, thereby forming a support ring or support plane at the top of the first support member. By setting the position of the support ring or support plane, it can be made to form a bipedal support structure composed of two contact surfaces together with the second support member. At this time, as long as the center of gravity of the terminal when placed falls within the overall projection area of ​​the support structure, the terminal can still remain stable when placed.

[0097] See also Fig.14 , Fig.14 A three-dimensional schematic diagram of a mobile terminal of some embodiments of the present disclosure is shown. In some embodiments, the mobile terminal may further include an additional connection fixture, which may be, for example, a terminal lanyard fixedly connected to the back panel of the terminal, with both ends of the lanyard fixedly arranged on the back panel of the terminal by means of bolts or the like, so as to facilitate holding the terminal and prevent the terminal from accidentally falling off.

[0098] See also Fig.15 and Fig.16 , Fig.15 A three-dimensional schematic diagram of a mobile terminal according to some embodiments of the present disclosure is shown. Fig.16 A schematic diagram of a changing state of the embodiment shown in the figure is shown. In some embodiments, a movable support member may also be connected to the second support member, and the movable support member is used to further support the terminal. For example, the movable support member may be a support frame hingedly connected to the protruding portion of the second support member. The support frame may, for example, be roughly in the shape of a long strip, and one end along its length direction is hinged to the surface of the second support member by means of a hinge device, so that the support frame as a whole can pivot around the hinge axis of the hinge device. In some embodiments, the hinge axis of the hinge device can be arranged parallel to the length direction of the terminal. In this case, when the support frame as a whole is pivoted around the hinge axis to turn away from the terminal and unfolded, the side surface of the bottom end of the support frame can form a triangular support structure with the bottom of the terminal. At this time, when the terminal is placed on a placement plane, the terminal can be erected with the support of the support frame and the bottom edge of the terminal. Those skilled in the art will appreciate that, although the above describes an embodiment in which the bottom side of the support frame is arranged to be parallel to the bottom side of the terminal, the present disclosure does not limit the specific arrangement of the support frame. For example, the hinge device can be arranged to have a certain inclination angle with respect to the length direction of the terminal so that the support frame can be unfolded at an inclination angle, thereby allowing the terminal to have a certain elevation angle when standing, or the inclination angle of the hinge device relative to the terminal can be arranged to be adjustable as needed.

[0099] See also Fig.17 , Fig.17A three-dimensional schematic diagram of a mobile terminal of some embodiments of the present disclosure is shown. A scheme having another movable support member in some embodiments of the present disclosure is shown. In this embodiment, the second support member is configured to have a fixing groove that is recessed inwardly along the circumference of its support portion, and the movable support member includes a fixing ring that is roughly elliptical in shape, which surrounds the outer circumference of the fixing groove, and the inner side of the fixing ring is embedded in the fixing groove, so that the fixing ring is connected to the second support member in a rotatable manner. The fixing ring is connected to a quick-release buckle in a detachable buckle connection manner. With the help of the combination of the fixing ring and the quick-release buckle, the movable support member can be further connected to other components, such as a fixed lock buckle, a wristband, etc., so that the terminal can be connected or supported on other supports in an unrestricted manner.

[0100] See also Fig.18 , Fig.18 A three-dimensional schematic diagram of a mobile terminal of some embodiments of the present disclosure is shown. In some embodiments, the second support member may further include a housing portion. The housing portion may, for example, be a card package fixedly connected to the support portion of the second support member, and the card package may, for example, be roughly in the shape of a flat box, which is fixedly connected to the second support member at one corner, and may be fixedly connected to the terminal back panel at the other three corners by means of mechanisms such as screws. The interior of the card package may include a housing cavity for accommodating cards, change, etc. In some embodiments, the height of the card package perpendicular to the plane of the terminal back panel may be flush with the height of the second support member, so that the plane of the card package can support the terminal together with the second support member, thereby further improving the stability of the terminal when placed.

[0101] See also Fig.19 , Fig.19 A three-dimensional schematic diagram of a mobile terminal of some embodiments of the present disclosure is shown. In some embodiments, the second support member is configured to have a hollow structure, and a receiving cavity is defined therein. The receiving cavity can be used to receive a fragrance agent such as a solid fragrance, so as to provide a fragrance effect to a user when used as an aromatherapy box 500. In some embodiments, the receiving cavity can be connected to the outside through an axial opening provided on the axial end face of the support portion and / or a side opening provided on the circumferential side face of the support portion, so as to release the fragrance substance outward.

[0102] In addition, in some embodiments, since the screw / connection structure is made of metal, the second support member may include an electronic component module, and the sensor may be electrically connected to the identification control module of the terminal through a connection structure such as a screw. For example, in some embodiments, a pressure sensor is provided on the outer surface of the second support member to provide a pickup of a pressing signal, thereby issuing a control instruction to the terminal.

[0103] In some embodiments, a physical button may also be provided on the supporting portion of the second supporting member, for example, and at the same time, a button with a certain damping effect may be made on the protruding portion of the second supporting member.

[0104] In some embodiments, in addition, a button can be set on the protruding side of the support part of the second support member, the surface close to the side of the mobile phone, etc., and when pressed, it can be pressed in the direction of the rotation axis of the support part. By making corresponding settings for the identification control module of the terminal, after the terminal detects the second support member including the corresponding accessories, different button functions can be activated in response to the pressing of the corresponding button. For example, when playing a game, pressing the button on the second support part can customize a specific effect; or as a shortcut switch, the button gesture is associated with the control instruction of the music playback software to control the playback status of the music, such as pressing once to control play / pause, pressing twice to control cutting to the next song, pressing three times to control cutting to the previous song, and long pressing to switch the playback effect, such as switching between noise reduction mode and transparency mode; in addition, when there is a light strip on the back of the mobile phone, the button can be used as a touch switch for starting or turning off the light strip.

[0105] It is understandable that the electronic components of the buttons may also include touch sensors, so that in addition to the above embodiments, more gestures may be recognized, such as sliding, multi-finger operation, etc.

[0106] A display screen can also be set up to provide more interactive effects.

[0127] The mobile terminal disclosed in the present invention comprises a mobile terminal body, a locking member and a back cover. The mobile terminal body is provided with a mounting slot, and the back cover has an assembly position corresponding to the mounting slot. During installation, the locking member passes through the assembly position on the back cover and is inserted into the mounting slot for fixing, thereby fixing the back cover on the mobile terminal body.

[0128] The locking member in the present disclosure is also equipped with an accessory assembly, which can be installed on the mobile terminal through the locking member. When the locking member is assembled, the accessory assembly at least partially protrudes from the surface of the rear cover. Specifically, the accessory assembly is fixedly connected to the end of the locking member away from the rear cover. Since the locking member is detachably connected to the mounting slot, the accessory assembly can also be removed from the mobile terminal for replacement and other operations.

[0129] In the solution provided by the present disclosure, the locking member can not only fasten the back cover and the mobile terminal body, but also install the accessory component on the mobile terminal, avoiding the need for an additional mounting structure to fix the accessory component to the mobile terminal. This solution can save costs.

[0130] In the above solution, the inner side wall of the installation groove has an internal thread, the locking member has an external thread, and one end of the locking member passes through the assembly position on the back cover and is threadedly connected to the installation groove, thereby fixing the accessory assembly to the mobile terminal.

[0131] The solution of this embodiment also includes: the mobile terminal also includes a camera decoration piece protruding from the surface of the back cover, the back cover is placed face down on a plane, the accessory assembly and the camera decoration piece are in contact with the plane to support the mobile terminal, so that the back cover is suspended above the plane.

[0132] The mobile terminal disclosed in the present invention is also provided with a camera decoration. Due to factors such as the lens combination or focal length requirements, the camera decoration often has a relatively large thickness, which makes it inevitable that it protrudes from the back cover surface of the mobile terminal. Since the accessory component is also provided protruding from the back cover surface, when the mobile terminal is placed on a plane, the accessory component and the camera decoration are in contact with the plane to support the mobile terminal, so that the back cover is suspended above the plane, thereby preventing the back cover from being scratched or rubbed, resulting in scratches or wear.

[0133] The solution of this embodiment also includes: the mobile terminal is provided with N accessory components, wherein N is a positive integer greater than or equal to; the assembly position includes at least a first assembly position and a second assembly position, the first accessory component has an extended length and has two ends, wherein the two ends are respectively connected to the first assembly position and the second assembly position. The center of gravity of the mobile terminal is located between the line connecting the first assembly position and the second assembly position and the center of the camera decorative piece.

[0134] In a specific embodiment, a plurality of accessory components with different functions may be installed on the mobile terminal, such as an aromatherapy box, a bracket, a lanyard, etc. Different accessory components may be installed on the mobile terminal separately, or two or three accessory components may be installed on the mobile terminal at the same time.

[0135] In this solution, the accessory component includes a first accessory component, the first accessory component has an extended length and has two ends, and the two ends of the first accessory component are connected to two locking members, so that the first accessory component is fixedly installed on the mobile terminal. The number of mounting slots, assembly positions and locking members is consistent. In this solution, since the two ends of the first accessory component are fixed on the mobile terminal, it is necessary to set two mounting slots on the mobile terminal body, namely the first mounting slot and the second mounting slot. Two assembly positions are also correspondingly set on the back cover, namely the first assembly position and the second assembly position. The two locking members are respectively fixedly connected to the first mounting slot and the second mounting slot through the first assembly position and the second assembly position, so that the two ends of the first accessory component are installed on the mobile terminal. The camera decoration is usually set at the upper left corner of the mobile terminal, and the two ends of the first accessory component are respectively set at the left and right ends of the mobile terminal, so that the center of gravity of the mobile terminal is located between the line connecting the first assembly position and the second assembly position and the center of the camera decoration.

[0136] The solution of this embodiment also includes: the back cover also has a second accessory component protruding from its surface, the back cover is placed face down on a plane, the first accessory component and the second accessory component are in contact with the plane to support the mobile terminal, so that the back cover is suspended above the plane.

[0137] In a specific solution of this embodiment, the mobile terminal is provided with not only a first accessory component but also a second accessory component different from the first accessory component, wherein the second accessory component is also provided at least partially protruding from the surface of the back cover. Since both the first accessory component and the second accessory component are provided protruding from the surface of the back cover, when the mobile terminal is placed on a placement plane such as a desktop, the back cover of the mobile terminal will be separated from the placement plane by the support of the first accessory component and the second accessory component, thereby avoiding being scratched or rubbed, resulting in scratches or wear.

[0138] In the above scheme, the first accessory component can be a supporting structure that only provides support for the first support member, and the second accessory component can be a card package. The card package includes a bottom plate that abuts against the back cover of the mobile terminal, and a card package body that is arranged above the bottom plate and magnetically connected to it, and the card package body has a receiving cavity inside for accommodating cards, change, etc. The card package can be, for example, roughly in the shape of a flat box, and the bottom plate is fixedly connected to the first accessory component at one corner, and can be fixedly connected to the back cover of the mobile terminal at the other three corners by means of screws and other mechanisms. In some embodiments, the height of the card package perpendicular to the plane of the back cover of the mobile terminal can be flush with the height of the first accessory component, so that the plane of the card package can support the mobile terminal together with the first support component, thereby further improving the stability of the mobile terminal when placed. In some embodiments, the card package body can also have a variety of different sizes and structures, so that different contents can be accommodated according to different usage needs. Each card package body is provided with a magnetic suction mechanism corresponding to the magnetic suction member on the bottom plate, so that it can be easily disassembled and replaced when needed.

[0139] The solution of this embodiment also includes: the mobile terminal is provided with a sensor for detecting the status information of the N accessory components. The sensor is a Hall element, and the N accessory components are provided with magnetic parts with different magnetic fluxes. The Hall element identifies different accessories according to the information of the magnetic parts.

[0140] The solution of this embodiment also includes: the accessory assembly includes: an accessory body; a rotating part, connected to the fixed body; a connecting part, one end of which is connected to the rotating part and the other end is fixedly connected to the locking member, and the rotating part is rotatably connected to the connecting part along the axis.

[0141] In the above solution, the accessory assembly includes an accessory body, a rotating part and a connecting part which are connected in sequence. The connecting part is fixedly connected to one end of a locking member. The accessory body is fixed to the mobile terminal by the locking member. The rotating part can be rotatably connected to the connecting part along its axis, so that the accessory body can rotate relative to the connecting part.

[0142] In the present disclosure, the locking member is a stud, the outer surface of the stud has an external thread, the inner wall of the mounting groove has an internal thread, the stud passes through the back cover and is threadedly connected to the mounting groove on the mobile terminal, thereby fixing the accessory body to the mobile terminal.

[0143] like Fig.23 -24, Fig.23 A cross-sectional schematic diagram of an accessory assembly of a mobile terminal according to some embodiments of the present disclosure is shown. Fig.24 Shows Fig.23An enlarged schematic diagram of part A in the figure. In a specific embodiment, the accessory body is a lanyard body 201, and one end of the lanyard body is connected to the rotating part. Specifically, the cross-section of the lanyard body is circular, and an annular raised structure is provided at the end of the lanyard body. The rotating part includes a tightening ring and a fixing ring, wherein the tightening ring is a tubular structure having a certain extension length and openings at both ends, and its inner surface has an annular limiting portion protruding toward the axial direction of the tightening ring. The lanyard body and the tightening ring are injection molded together, and the raised structure at the end of the lanyard body is clamped and limited with the limiting portion. In this solution, the fixing ring is also a tubular structure having a certain extension length and openings at both ends, the extension length of the fixing ring is greater than the extension length of the fixing ring, and the diameter of the cross-section of the fixing ring is also greater than the diameter of the cross-section of the fixing ring. When the end of the lanyard body is fixedly connected to the tightening ring, the tightening ring is inserted into the fixing ring and the two are connected by injection molding.

[0144] In an optional solution of this embodiment, the height of the side of the fixing ring away from the rear cover surface protruding from the rear cover surface is the same as the height of the camera decoration piece protruding from the rear cover surface. When both ends of the lanyard body are connected to the mobile terminal, the two fixing rings at both ends of the lanyard body and the camera decoration piece form a triangle, and when the mobile terminal is placed on a plane, the rear cover does not abut against the plane, thereby preventing the rear cover from being scratched or damaged.

[0145] In this solution, the connecting part is an integrally formed bent tube, and the bent tube includes a first straight tube section, a bent section, and a second straight tube section connected in sequence. In the assembled state, the first straight tube section is arranged perpendicular to the rear cover of the mobile terminal and is fixedly connected to the stud, and the second straight tube section is arranged parallel to the rear cover of the mobile terminal and is connected to the fixing ring connected to the end of the lanyard body.

[0146] The fixing ring is detachably connected to the second straight pipe section by plugging and pulling. Specifically, the end of the second straight pipe section away from the bending section has a first diameter section and a second diameter section, and the diameter of the first diameter section is smaller than the diameter of the second diameter section. And the diameters of the first diameter section and the second diameter section are both smaller than the diameter of the cross section of the fixing ring. The side of the fixing ring away from the end of the lanyard body has a first protruding structure protruding along the circumference of its inner wall, and the first diameter section has a second protruding structure protruding along the circumference of its outer wall, and there is a certain length of interval between the second protruding structure and the second diameter section. During installation, the first protruding structure is inserted into the interval between the second protruding structure and the second diameter section under the action of external force, so that the rotating part can be rotatably connected to the connecting part along its axis.

[0147] Since the end of the lanyard body needs to be connected to the rotating part by injection molding, the end of the lanyard body is connected to the rotating part and the whole is used as a standard part. The lanyard body can be connected to the mobile terminal at only one end, or both ends. When both ends of the lanyard body are connected to the mobile terminal, then the two connecting parts are first connected to the mobile terminal, and then the two ends of the lanyard body are rotatably connected to the connecting part through the rotating part. Or after one end of the lanyard body is first connected to the connecting part, the connecting part fixes one end of the lanyard body to the mobile terminal by a screw, and after the other connecting part is also rotatably fixed to the mobile terminal, the other end of the lanyard body is connected to the connecting part through the rotating part.

[0148] In the above solution, since both ends of the lanyard body are fixed on the mobile terminal, even if the stud and the mounting groove are not fully assembled in place, the back cover can still be fixed on the mobile terminal body.

[0149] In a specific embodiment, the lanyard body is made of a flexible material with elastic deformation, and when both ends of the lanyard body are fixed on both sides of the mobile terminal, the lanyard body is attached to the back cover of the mobile terminal. When the user uses it, the finger is inserted between the lanyard body and the back cover, thereby fixing the mobile terminal on the user's hand.

[0150] like Fig.25 As shown, Fig.25 A three-dimensional schematic diagram of a mobile terminal of some embodiments of the present disclosure is shown. In another implementation of the present embodiment, the accessory component is a bracket.

[0151] See also Figure 26 to Figure 29 , Fig.26 A schematic side view of an accessory assembly of a mobile terminal according to some embodiments of the present disclosure is shown; Fig. 27 A three-dimensional schematic diagram showing an accessory assembly of a mobile terminal according to some embodiments of the present disclosure; Fig.28 A three-dimensional schematic diagram of a turntable assembly of a mobile terminal according to some embodiments of the present disclosure is shown. Fig.29A three-dimensional schematic diagram of a turntable assembly of a mobile terminal of some embodiments of the present disclosure is shown. In this solution, the bracket includes a turntable assembly, a stud and a support assembly. The turntable assembly is connected to the support assembly, and the stud mounts the turntable assembly on the mobile terminal. Specifically, the turntable assembly is a circular structure, which includes an upper turntable and a lower turntable arranged relatively. The middle area of ​​the upper turntable and the lower turntable is respectively provided with through holes that rotate relative to each other along the first rotation axis. After the stud passes through the through holes of the upper turntable and the lower turntable in turn, the back cover is fixed to the mobile terminal by cooperating with the assembly position on the back cover. At the same time, the stud also fixes the turntable assembly on the back cover of the mobile terminal. Among them, the stud is fixedly connected to the lower turntable and is relatively rotatably connected to the upper turntable. The support assembly is connected to the upper surface of the upper turntable through a rotating shaft, and the angle between the upper turntable and the support assembly is changed by rotating along the second rotating shaft. When the bracket is installed on the back cover of the mobile terminal, it can provide support at multiple angles to the mobile terminal.

[0152] In a specific solution of this embodiment, the upper turntable and the lower turntable can rotate relative to each other. Specifically, an annular groove structure is provided at the connection between the lower turntable and the upper turntable, and a stopper is provided in the groove structure. The upper turntable is an open groove-shaped structure, and the inner surface of the upper turntable has a protruding sliding portion. When the upper turntable and the lower turntable are matched, the side wall cover of the upper turntable is provided on the outer periphery of the side wall of the lower turntable, and the sliding portion on the surface of the upper turntable is inserted into the groove structure and can slide along the groove structure and rotate around the first rotation axis.

[0153] The support assembly includes an upper support plate, a lower support plate, and a metal piece 303 disposed therebetween. The metal piece is a plate-shaped structure, one end of which is fixedly connected to the lower support plate. The other end is wrapped around the second shaft at a second shaft to form a second shaft rotating portion. The upper support plate has a certain thickness and a recessed area on its lower surface. The lower support plate with the metal piece fixed thereto is fixed in the recessed area of ​​the upper support plate by injection molding, and the surface of the upper support plate after injection molding is a planar structure.

[0154] The upper turntable has a mounting portion 304 protruding from its upper surface. The mounting portion includes side walls oppositely arranged on one side of the through hole, and the two side walls have oppositely arranged fixing holes. The second rotating shaft rotating portion on the metal part has a mounting hole, and the mounting hole is arranged between the two fixing holes. The second rotating shaft passes through the mounting hole and the two fixing holes to rotatably connect the turntable assembly 301 and the support plate assembly 302.

[0155] In this solution, when the bracket is installed on the mobile terminal, there are two operating modes. One is to insert the lower end of the stud through the assembly part into the installation slot on the mobile terminal body, and then rotate the lower turntable 3012 to fix the bracket on the mobile terminal. The other mode is to insert the lower end of the stud through the assembly part into the installation slot on the mobile terminal body, and then rotate the support assembly. At this time, if the sliding part does not abut the stopper, the sliding part slides in the groove structure, the support assembly drives the upper turntable to rotate, and the lower turntable does not rotate. When the sliding part slides to the position of the stopper and abuts the stopper, the upper turntable continues to rotate in the same direction. At this time, the upper turntable and the lower turntable drive the stud to rotate together, so that the screw is threadedly connected to the installation slot.

[0156] It will be understood by those skilled in the art that, although the above describes an embodiment in which an assembly part is used to fix a lanyard or a bracket, in some embodiments, the assembly part can be used to fix other types of accessory components. For example, one or more mounting holes on an assembly component can correspond to one or more of the multiple assembly parts, so that the assembly component can be connected to the back of the mobile terminal with the aid of a connector such as a bolt. At the same time, according to actual usage, the assembly component can be flexibly set at the corresponding position of some of the multiple assembly parts, further enriching its types of uses.

[0157] In a specific solution of this embodiment, the stopper has a certain extension width in the groove, so that the groove structure becomes an open ring with an angle of no more than 10° around the first rotation axis. That is, the sliding angle of the sliding part in the groove structure along the first rotation axis does not exceed 10°.

[0158] In an optional embodiment, the relative rotation angle between the upper rotating disk and the lower rotating disk is not less than 100°. That is, when the bracket is assembled on the mobile terminal, but the user does not need the bracket to play its supporting role, the user can rotate the bracket from the horizontal setting to the vertical setting, or from the vertical setting to the horizontal setting, so as to avoid the bracket blocking the user from directly contacting the mobile terminal and affecting the user's experience.

[0159] In an optional implementation of this embodiment, the rotation angle of the support assembly along the second rotation axis is greater than ° and less than °. In this solution, since a vertical placement of less than ° is insufficient to support the mobile terminal, and if it is greater than °, the support strength of the mobile terminal will decrease, the rotation angle of the support assembly is set to between ° and .

[0160] In a specific implementation of this embodiment, a protruding structure is provided on the lower surface of one end of the lower support plate away from the second rotation axis. When the bracket is fixed to the back cover of the mobile terminal and the bracket is in the storage state, the protruding structure abuts against the back cover, and both ends of the support plate assembly protrude from the back cover surface of the mobile terminal, forming a support surface parallel to the back cover. When the mobile terminal is placed on a plane, the bracket supports the mobile terminal to prevent the back cover from contacting the plane.

[0161] In a specific implementation of this embodiment, since the turntable assembly has a certain thickness, when the turntable assembly is installed in the edge area of ​​the mobile terminal, if the mobile terminal is tilted at a certain angle range, the edge of the back cover of the mobile terminal and the edge of the turntable assembly form a support line, and the tilt angle of the support line is smaller than the tilt angle of the bracket. In this case, the bracket cannot provide a good support for the mobile terminal. In order to avoid this situation, a avoidance zone is provided at the edge area of ​​the turntable assembly close to the mobile terminal.

[0162] See also Figure 30 to Figure 33 ,in Fig.30 A three-dimensional schematic diagram showing an accessory assembly of a mobile terminal according to some embodiments of the present disclosure; Fig.31 A three-dimensional schematic diagram showing a base of an accessory assembly of a mobile terminal according to some embodiments of the present disclosure; Fig.32 A three-dimensional schematic diagram showing a combined state of a base and a mounting base of a mobile terminal according to some embodiments of the present disclosure; Fig.33 A three-dimensional schematic diagram of a cover of an accessory assembly of a mobile terminal according to some embodiments of the present disclosure is shown. In a specific solution of the present embodiment, the accessory assembly is an aromatherapy box.

[0163] The aromatherapy box includes a base 501, a mounting seat 502 and a cover body 503. Specifically, the base is a circular groove with an opening facing upward, and a through hole is provided on the base for the locking member to pass through. The mounting seat is installed in the circular groove, and the mounting seat is a disc-shaped structure, and has a mounting hole in the middle that passes through the disc-shaped structure. Two limiting grooves are provided on the peripheral wall of the mounting hole, wherein the positions of the two limiting grooves are relatively arranged and are formed by extending radially outward along the disc-shaped structure. The locking member has a threaded section and a fixed section. After the threaded section passes through the through hole, the fixed section abuts against the inner surface of the mounting seat, and the diameter of the mounting hole is larger than the diameter of the fixed section, thereby forming an avoidance area for the fixed section.

[0164] The cover of the aromatherapy box is a plate-like structure with a through hole in the middle. A fastener is provided at the through hole to cooperate with the fixed section on the locking member. Two claw structures are provided on the periphery of the fastener, and the two claw structures are respectively provided corresponding to the two fixed grooves on the mounting seat. The claw structure includes a first claw and a second claw. The outer wall of the first claw abuts against the inner wall of the limiting groove, and the lower side wall of the second claw abuts against the upper surface of the mounting seat. During installation, the fastener is sleeved on the periphery of the fixed section, and the two claws abut against the fixed seat to fix the cover on the mounting seat.

[0165] The base peripheral wall of the aromatherapy box disclosed in the present invention has a plurality of extensions, wherein the plurality of extensions are arranged at intervals. When the cover body is fixed to the mounting base, the lower surface of the cover body abuts against the upper ends of the plurality of extensions, thereby forming a hollow area between the plurality of extensions, providing a diffusion channel for the aroma inside the aromatherapy box.

[0166] During use, aromatherapy tablets or other solid aromatherapy materials are placed in the aromatherapy box, the cover is installed, and then the aromatherapy box is fixed on the mobile terminal through the cooperation of the locking member and the installation slot.

[0167] In addition, in some embodiments, the present disclosure further provides a protective case for a terminal, which can be, for example, independent of the mobile terminal body and detachably mounted on the back of the terminal. The protective case can, for example, include a first support member and a second support member protruding perpendicularly to the back plane of the protective case, and a positioning groove for mounting the second support member is provided on the mobile phone protective case, and the second support member is detachably disposed in the positioning groove.

[0168] It can be understood by those skilled in the art that the various second support members described in the above-mentioned embodiments can be used in the form of independent backplane accessories in conjunction with the same or similar terminals. That is, each backplane accessory includes the same or similar connection part and can be installed correspondingly with the corresponding connection mechanism on the backplane of the corresponding terminal. In this way, it is possible to interchange various backplane accessories on the same terminal according to different needs, allowing users to select the actual accessories they need to use according to the actual usage scenario, which greatly improves the scalability of the terminal functions.

[0169] By providing a first support member and a detachable second support member, the mobile terminal of some embodiments of the present disclosure can prevent the back plate of the terminal from directly contacting the placement plane, and can prevent the terminal from being unable to be placed flat due to the raised portion of the camera assembly, so that it contacts the placement plane in an inclined posture, resulting in additional wear of the contact portion. Furthermore, by providing the second support member as a separately replaceable back plate accessory, it can be replaced more flexibly and conveniently when wear occurs, and provides customers with more flexible choices.

[0170] The antenna module disclosed herein covers the first antenna body with a first decorative piece composed of a conductor, so that the first decorative piece and the first antenna body can ensure a suitable positional relationship to meet the coupling amount requirement between the first antenna body and the first decorative piece. When the first antenna component is fed, the first antenna component can resonantly couple the first decorative piece to excite the resonance of the first decorative piece. In some embodiments, the resonant frequency of the first decorative piece can also be adjusted to the desired resonant frequency through the decorative piece matching network of the first decorative piece, thereby increasing the antenna bandwidth and antenna efficiency. At the same time, by providing an electrostatic protection component electrically connected to the first decorative piece, the first decorative piece can also have an anti-static function.
