[0002] With the rapid development of the fifth-generation mobile communication technology (5G), the requirements for the frequency bands supported by mobile communication devices are constantly increasing, and the number of antennas in mobile communication devices is also increasing accordingly.

When the clearance of the antenna decreases, the near-field current distribution of the antenna is affected, which in turn affects the impedance matching and radiation pattern of the antenna. This results in the deterioration of the radiation performance and bandwidth of the antenna, leading to a decline in the user communication experience. Summary of the Utility Model

[0056] In view of this, the embodiments of the present disclosure provide an antenna module solution, which can enhance the performance of the antenna component by providing an antenna adjustment member at a certain distance from the antenna component. The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings.

[0057] First, refer toFigure 1 and Figure 3 , Figure 1 shows an exploded schematic view of an antenna module according to some embodiments of the present disclosure; Figure 3 shows a perspective view of an antenna module according to some embodiments of the present disclosure, in which the rear cover 22 is removed for clarity. The antenna module 100 according to some embodiments of the present disclosure may be, for example, an antenna transceiver mechanism for receiving or transmitting electrical signals for a mobile device. The antenna module 100 may include a housing, and a main board 10 and a main board support 19 disposed inside the housing. An antenna assembly 30 may be further disposed on the main board support 19, and an antenna adjustment member 40 may be fixedly connected to the housing to enhance the performance of the antenna assembly 30. The antenna adjustment member 40 may be disposed at a certain distance from the antenna radiator 31 of the antenna assembly 30, and the antenna radiator 31 is used for electrically connecting to the main board 10. For example, in some embodiments, the housing may be a hollow frame structure with the main board 10 fixedly disposed inside.

[0058] The main board 10 may be an electronic main board provided with an electronic control component, etc., and the main board 10 is also fixedly connected to the plate-shaped main board support 19. An antenna assembly 30 for transmitting or receiving radio signals may be disposed on the main board support 19 or the main board 10. The antenna assembly 30 includes an antenna radiator 31 for transmitting or receiving radio signals, and the antenna radiator 31 is used for electrically connecting to the corresponding electronic control component on the main board 10 to process the received electromagnetic wave or convert the information to be transmitted into an electromagnetic wave through the antenna assembly 30 for transmission. In some embodiments, the antenna adjustment member 40 may include, for example, a cylindrical main body portion, which is fixed relative to the housing and exposed outside the housing. At the same time, the shortest distance b between the outer peripheral edge of the main body portion of the antenna adjustment member 40 and the edge of the antenna radiator 31 satisfies: 0 < b ≤ 0.25λ with respect to the electromagnetic wave wavelength λ of the antenna assembly 30 in the operating frequency band. Those skilled in the art can understand that in some other embodiments, the antenna adjustment member 40 may also be formed into other shapes, such as a prism shape, etc., as long as the shortest distance b between its outer peripheral edge and the edge of the antenna radiator 31 satisfies 0 < b ≤ 0.25λ.

[0059] Specifically, in some embodiments, the housing may include a middle frame 20 generally in the shape of a rectangular plate and a rear cover 22 also generally in the shape of a rectangular plate. Among them, one of the middle frame 20 or the rear cover 22 may include an outer edge 221 extending perpendicular to the rectangular plate surface at its circumferential outer edge. For example, the above-mentioned outer edge 221 protruding perpendicular to the plate surface of the rear cover 22 may be provided on the rear cover 22, so that the outer edge 221 can contact the outer peripheral portion of the middle frame 20. By setting the shape of the outer edge 221 to cooperate with the middle frame 20, the middle frame 20 and the rear cover 22 can be buckled to each other by the cooperation of the outer edge 221 and the outer peripheral portion of the middle frame 20, and a receiving space is defined inside the two. In this receiving space, a main board 10 generally in the shape of a rectangular plate may be provided. The main board 10 may include a substrate for carrying electronic devices and electronic devices provided on one or both sides of the substrate. In some embodiments, the middle frame 20 has a first surface facing the screen and a second surface facing away from the screen which are oppositely arranged, wherein the middle frame 20 is electrically connected to the main board 10, and the antenna adjusting member 40 protrudes from the first surface or the second surface of the middle frame 20 to one side.

[0060] In some embodiments, the antenna module may further include a main board support member 19 generally in the shape of a rectangular plate. The middle frame 20, the main board 10, the main board support member 19 and the rear cover 22 may be sequentially stacked, wherein the main board 10 and the main board support member 19 may be arranged inside the receiving space enclosed by the middle frame 20 and the rear cover 22. An antenna assembly 30 may be fixedly provided on the main board 10 or the main board support member 19. The antenna assembly 30 may include, for example, an antenna radiator 31 for transmitting and receiving electromagnetic waves. The antenna assembly 30 may be electrically connected to the main board 10, so as to convert the guided wave of the communication signal transmitted from the main board 10 end into an electromagnetic wave capable of being transmitted in space, and can also receive the electromagnetic wave transmitted in space and convert it into a guided wave on the main board 10. In some embodiments, the antenna module may further include an antenna adjusting member 40 formed with a cylindrical main body portion. An enhancement member mounting hole 223 for the antenna adjusting member 40 to pass through may also be provided on the rear cover 22. The antenna adjusting member 40 at least partially passes through the enhancement member mounting hole 223, so that a part of the antenna adjusting member 40 is adjacent to the edge portion of the antenna radiator 31 of the antenna assembly 30 in the horizontal direction.

[0061] See also Figure 2 and Figure 3 , Figure 2FIG. 0 shows a partial cross-sectional schematic view of an antenna module according to some embodiments of the present disclosure, in which, for clarity, the main board 10, the main board support 19, and the rear cover 22 are removed. In some embodiments, the antenna adjusting member 40 may include, for example, an antenna screw, which includes a stud 43 and a head 41. The stud 43 is arranged towards the middle frame 20, and the head 41 is arranged away from the middle frame 20. Wherein, the middle frame 20 may be provided with a fixing portion for threadedly connecting with the stud 43, and the fixing portion includes a threaded portion for threadedly connecting with the stud 43 of the antenna adjusting member 40. In some embodiments, the fixing portion may be integrally formed with the middle frame 20, so that the antenna adjusting member 40 threadedly connected with the fixing portion can be electrically connected to the middle frame 20 at the same time. In some embodiments, the middle frame 20 may be made of a metal material, and the middle frame 20 may be exposed on the mobile device, so that the antenna adjusting member 40 is actually grounded by means of the middle frame 20. At the same time, the rear cover 22 may be made of a non-metallic material such as plastic, glass, leather, etc., so as to facilitate the transmission of electromagnetic waves. In addition, the rear cover 22 may also be arranged to be connected in a manner that can be detached relative to the middle frame 20, so as to facilitate the user to access its internal accommodation space for corresponding maintenance.

[0062] Refer again to Figure 2 and Figure 3 , wherein Figure 2 and Figure 3 also shows the positional relationship between the antenna adjusting member 40 and the antenna assembly 30 according to some embodiments of the present disclosure. In Figure 2 the illustrated embodiment, the antenna adjusting member 40 protrudes from the main board 10 surface in a direction perpendicular to the main board 10 surface, wherein the overall axial length of the antenna adjusting member 40 is a, and the length of the part protruding from the middle frame 20 surface is x. In Figure 3 , for example, the central axis Y of the main body part of the antenna adjusting member 40 is perpendicular to the main board support 19 surface, and the antenna radiator 31 of the antenna assembly 30 is generally rectangular and stacked on the upper surface of the main board support 19. Wherein, the antenna radiator 31 includes a short side and a long side, and the distance between one short side and the circumferential edge of the main body part of the antenna adjusting member 40 is the closest, and this distance is defined as b here, and the projection length of the antenna adjusting member 40 in the direction of the antenna radiator 31 is c.

[0063] According to the resonance principle of the antenna, the length a of the antenna adjusting member and the length x of the part exposed on the surface of the middle frame mainly affect the frequency of parasitic resonance. When conditions permit, the closer x is to 0.25nλ, the better the antenna enhancement effect. And the distance b mainly affects the coupling between the antenna assembly 30 and the antenna adjusting member 40. The smaller the distance b, the stronger the coupling between the two. In addition, the longer the length c of the projection of the antenna adjusting member 40 onto the antenna assembly 30, the stronger the coupling between the two. Through software simulation experiments, the dimensional parameters related to the antenna adjusting member can be limited to a predetermined range, so as to approach the ideal coupling state. For example, in some embodiments, when the electromagnetic wave wavelength corresponding to the operating frequency band of the antenna assembly 30 is λ, the value range of the distance b is: 0 < b ≤ 0.25λ. That is, at this time, the distance b is greater than 0 and less than or equal to one-fourth of the electromagnetic wave wavelength λ corresponding to the operating frequency of the antenna assembly 30. At the same time, the value range of the length c is: c ≥ 0.02λ, that is, at this time, the distance c is greater than or equal to one-fiftieth of the electromagnetic wave wavelength λ corresponding to the operating frequency of the antenna assembly 30. In some embodiments, the overall length a of the antenna adjusting member 40 is limited to 0.15nλ to 0.3nλ, and at the same time, the length x of the part protruding from the surface of the middle frame 20 satisfies x ≥ 0.15nλ, where n is an odd number. The above settings enable the antenna module to form a parasitic monopole resonance mode of n / 4 wavelength (n is an odd number) when operating in the corresponding frequency band with a wavelength of λ, thereby improving the bandwidth and radiation performance of the antenna.

[0064] The following will be described with reference to the S-parameter characteristic diagram and the system total efficiency characteristic diagram generated based on the solutions of different antenna modules to illustrate some embodiments of the antenna module according to the present disclosure. Refer to Figures 5a to 5d , wherein Figure 5a shows the S-parameter characteristic diagram of the antenna mechanism without the antenna adjusting member installed; Figure 5b shows the system total efficiency characteristic diagram of the antenna mechanism without the antenna adjusting member installed; Figure 5c shows the S-parameter characteristic diagram of the antenna mechanism with the antenna adjusting member installed;

[0065] Figure 5d shows the system total efficiency characteristic diagram of the antenna mechanism with the antenna adjusting member installed. In Figure 5a and Figure 5b In the related characteristic diagrams of the antenna mechanism without the antenna adjusting member shown, it can be seen that when the antenna adjusting member 40 is not provided and the clearance distance e around the antenna radiator 31 does not satisfy e ≥ 0.25λ, the bandwidth of the single resonance mode of the antenna cannot cover the entire N77 frequency band, and in this setting, the radiation efficiency of the antenna assembly 30 is poor, which will affect the user experience of the mobile communication terminal.

[0066] In contrast, refer to Figure 5c andFigure 5d In some embodiments, the antenna module may be provided with an antenna adjusting member 40. For example, when it is necessary to transmit and receive electromagnetic waves in the N77 frequency band, the antenna assembly 30 may be set to operate in this operating frequency band. Since the frequency range of the N77 frequency band is 3.3 GHz to 4.2 GHz, the corresponding electromagnetic wave wavelength λ is approximately 71 mm to 90 mm. It can be obtained therefrom that in the N77 frequency band, the range of the overall length a of the antenna adjusting member 40 may be 10.65 mm to 27 mm. In some embodiments, the overall length a of the antenna adjusting member 40 may be set to 18 mm. The distance b from the edge of the antenna radiator 31 to the axis of the main body portion of the antenna adjusting member 40 is 10 mm, or 0 < b ≤ 17.8 mm. And the range of the projection length c of the antenna adjusting member 40 in the direction of the antenna radiator 31 may be c ≥ 1.8 mm. In some embodiments, the closest distance c from one long side of the antenna radiator 31 to the axis of the main body portion of the antenna adjusting member 40 may be set to 1.8 mm. At the same time, the length x of the portion of the antenna adjusting member 40 protruding from the surface of the middle frame 20 satisfies x ≥ 13.5 mm. At this time, the antenna adjusting member 40 can be regarded as a part of the antenna, Figure 4 shows a schematic diagram of the current distribution on the antenna adjusting member 40 when the antenna module operates in the N77 frequency band, which is generated by using CST electromagnetic simulation software according to the above physical parameters. It can be seen from the figure that a quarter-wavelength monopole parasitic mode is excited on the antenna adjusting member 40 by the antenna, thereby improving the efficiency and bandwidth. According to Figure 5c and Figure 5d As can be seen from the schematic diagram of the relevant characteristics of the antenna adjusting member 40 shown, after adding the antenna adjusting member 40, the double-resonance range of the antenna module can generally cover the N77 communication frequency band. At the same time, the added antenna adjusting member 40 can also improve the radiation efficiency of the antenna, so that the efficiency of the antenna module in the entire N77 frequency band is higher than -5 dB. Therefore, this solution can effectively improve the antenna performance under the condition of a lower clearance distance, thereby optimizing the user communication experience of the mobile communication terminal.

[0067] See Figure 6 , Figure 6 shows an exploded view of the antenna module according to some embodiments of the present disclosure. In some embodiments, the antenna module may further include a solution for electrically connecting the antenna adjusting member 40 to the middle frame 20 in an indirect connection manner. For example, in this antenna module, a matching component 51 may also be provided. The matching component 51 may be, for example, a topological network component including capacitors and / or resistors and / or inductors disposed on a printed circuit board, and is mainly used to adjust the electrical length of the antenna adjusting member 40.

[0068] Specifically, in some embodiments, the matching component 51 is disposed between the middle frame 20 and the main board 10. One side of the matching component 51 is electrically connected to the main board 10, and the other side is electrically connected to the antenna adjusting member 40, so as to adjust the electrical length of the antenna adjusting member 40 under the control of the electronic control component on the main board 10. In some embodiments, the fixing portion of the middle frame 20 may further include an injection molding portion 27 and a metal nut 25 for threadedly connecting with the antenna adjusting member 40. The injection molding portion 27 may be directly formed in a corresponding injection molding receiving hole 29 on the middle frame 20 by injection molding, for example. At the same time, the metal nut 25 and the injection molding portion 27 may also be integrally formed or formed by hot melting in the injection molding receiving hole 29. The present disclosure does not limit the specific forming method of the injection molding portion 27 and the metal nut 25. For example, the injection molding portion 27 or the metal nut 25 may also be separately formed and disposed in the injection molding receiving hole 29 by means of shape matching, as long as it can be fixedly connected to the middle frame 20 insulatedly by means of the injection molding portion 27. In some embodiments, one end of the metal nut 25 is directly electrically connected to the antenna adjusting member 40, and the other end may be electrically connected to a metal gasket 50. The metal gasket 50 and the matching component 51 are both disposed on the main board 10. One side of the metal gasket 50 is electrically connected to the metal nut 25, and the other side is electrically connected to the matching component 51. Thus, the antenna adjusting member 40 is not directly electrically connected to the middle frame 20, but is connected through the metal nut 25, the metal gasket 50 and the matching component 51. Capacitors, inductors and other devices may be added to the matching component 51 to tune the electrical length of the antenna adjusting member 40.

[0069] Those skilled in the art can understand that although the above description mentions a specific setting method of an antenna module applied to the N77 communication frequency band in the 5G communication field, the specific parameters of each part of the antenna module can be adjusted according to various different specific usage requirements. For example, for the frequencies of 4G and other 5G communication frequency bands, the overall length a of the antenna adjusting member 40, the distance b between the edge of the antenna radiator 31 and the axis of the main body part of the antenna adjusting member 40, and the closest distance c between one long side of the antenna radiator 31 and the axis of the main body part of the antenna adjusting member 40 can be adjusted accordingly to cope with various different situations. In addition, in some embodiments, the antenna radiator 31 of the above antenna assembly 30 may be a metal trace on a separate component composed of an FPC (flexible printed circuit board), but the present disclosure does not limit the specific forming method of the antenna radiator 31. For example, in some other embodiments, the antenna radiator 31 may also be a metal trace directly formed by plating on a corresponding substrate (such as the main board support 19) through LDS (laser direct structuring), or the antenna radiator 31 may be an independent component composed of a steel sheet or other metals.

[0070] According to some embodiments of the present disclosure, by providing an antenna adjustment member with a specific size that is close to, but not directly electrically connected to, the antenna radiator, the antenna adjustment member can generate additional parasitic modes, such as an additional parasitic mode of a quarter wavelength. The generated parasitic mode resonates in the target operating frequency band, compensating for the deficiency of the original antenna bandwidth. By setting the distance b between the antenna adjustment member and the antenna radiator to be b ≤ 0.25λ, the coupling between the antenna adjustment member and the antenna radiator is strong, which can be regarded as expanding the antenna aperture of the original antenna radiator and improving the radiation efficiency of the antenna.

[0071] The following is based on Figures 7 to 31 Further describe several specific embodiments in which antenna modules with antenna adjustment members are applied to mobile terminals. Among them, each embodiment is provided with an antenna assembly and an antenna adjustment member 409 included in some embodiments of the present disclosure as described above. The antenna adjustment member 409 can be any one or more decorative screws adjacent to the antenna assembly on the backplane of several embodiments, or the metal screw part of a decorative fitting with a screw, and the closest distance b between the edge of the antenna adjustment member and the edge of the antenna radiator satisfies: 0 < b ≤ 0.25λ with respect to the wavelength λ of the electromagnetic wave in the operating frequency band of the antenna assembly.

[0072] In some embodiments, the antenna adjustment member can also be used to detachably fix a fitting to the rear case. Refer to Figure 15 , Figure 15 which shows a three-dimensional schematic diagram of a mobile terminal with a mobile terminal fitting according to some embodiments of the present disclosure. In some embodiments, the mobile terminal fitting can generally include an antenna adjustment member 409 fixedly connected to the rear case of the mobile terminal 400. Refer to Figure 15 wherein Figure 15 which shows a three-dimensional schematic diagram of a mobile terminal with a mobile terminal fitting according to some embodiments of the present disclosure. By providing the mobile terminal fitting, not only can additional auxiliary functions be provided for the mobile terminal 400, but also by making the antenna adjustment member 409 have an additional length, the length x of the part of the antenna adjustment member protruding from the surface of the middle frame can be increased without making the antenna adjustment member 409 protrude too much.

[0073] Embodiments of the present disclosure provide a mobile terminal. By providing a first support member protruding from the backplane of the terminal and a second support member that also protrudes from the backplane and is detachable, when the back cover is placed flat during the use of the terminal, the plurality of support members can form a support surface different from the main body of the back cover, so that the main body of the back cover is suspended above the plane, thereby avoiding damage such as friction and bumps caused by the contact between the back cover and the plane.

[0074] Refer to Figure 7 and Figure 8 , Figure 7A three-dimensional schematic diagram of a mobile terminal showing some embodiments of the present disclosure is shown. Figure 8 A side view schematic diagram of a mobile terminal showing some embodiments of the present disclosure is shown. In some embodiments, the mobile terminal may include a terminal body and a terminal back plate fixed to the terminal body. Among them, the terminal back plate may be generally rectangular, and a first support member is provided at a first corner thereof. The first support member protrudes from the terminal back plate in a direction perpendicular to the plate surface of the terminal back plate 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 plate. The second support member is detachably provided relative to the terminal back plate and also protrudes perpendicular to the terminal back plate plane for supporting the terminal body. Through the first support member and the second support member protruding perpendicular to the terminal back plate, when the terminal is placed on a placement plane such as a desktop, the terminal back plate will be spaced from the placement plane by the support of the first support member and the second support member, thereby avoiding being scratched and rubbed, resulting in scratches or wear.

[0075] Specifically, in some embodiments, the terminal may include a camera assembly provided at a first corner of its rectangular terminal back plate. Those skilled in the art can understand that due to factors such as lens combination or focal length requirements, the camera assembly often has a relatively large thickness, which makes it inevitably protrude from the back surface 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 include, for example, a main lens and its related components, while the second camera assembly may include, for example, a sub-lens and / or a flash and other camera-related components. The first camera assembly and the second camera assembly are spaced apart from each other. At the same time, the first support member may include two protruding portions, that is, two support rings protruding perpendicular to the terminal back plate plane. The first support ring may surround the outer periphery of the protruding portion of the first camera assembly, and the second support ring surrounds the outer periphery of the protruding portion of the second camera assembly, and the top ends of the protruding portions of the first support ring and the second support ring exceed the heights of the first camera assembly and the second camera assembly in the vertical direction of the terminal back plate. At the same time, the second support member is provided at a second corner of the terminal back plate opposite to the first corner. Here, the opposite means that the second corner is the diagonal of the first corner. Among them, 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 plate, 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 plate, so as to align with the outer peripheral portion of the terminal back plate and avoid structures such as steps that are likely 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 situations.

[0076] When the terminal backplane is placed face down on a placement plane such as a desktop, since the first support ring and the second support ring protrude beyond the first camera component and the second camera component in the direction perpendicular to the terminal backplane plane, they can replace the first camera component and the second camera component to contact the placement plane, so that the lens or the exposed optical device part will not directly contact the placement plane. Moreover, when the terminal backplane is placed face down, 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 opposite first corner and second corner, when the terminal is placed flat, the center of gravity of the terminal body will necessarily fall within the triangular support area formed by the three points in the direction perpendicular to the backplane surface. Therefore, when the terminal is placed flat, it can be ensured that it will not tilt due to its own weight, resulting in the situation that the terminal backplane or the side of the terminal backplane 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 terminal backplane plane can be flush with the distal ends of the second support member protruding from the terminal backplane plane, so that when the terminal backplane is placed face down, in the three-point support structure formed by the first support ring, the second support ring, and the distal ends of the second support member, the planes at the corresponding top ends of the three can all contact the placement plane as a whole, thereby spreading the terminal's own weight and the impact force during picking and placing by increasing the contact area, making the contact parts of the three with the placement plane less likely to be worn. At the same time, the three contact surfaces also make the placement of the terminal more stable and 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 in the direction perpendicular to the terminal backplane is.mm, so as to give a higher degree of freedom in the structural selection of the first support member and the second support member.

[0077] Common lens components currently often include an outer surface made of sapphire glass. By providing a support ring protruding perpendicular to the terminal backplane surface, even if the terminal is placed on any plane, the surface of the lens component inside the decorative ring will not be scratched. In addition, the support ring not only protects the surface of the lens component inside it from contacting the placement plane, but also prevents the entire first support member and other surfaces of the terminal backplane near the first corner from being scratched.

[0078] In this way, even when materials such as plastic and leather with generally poorer wear resistance than metal are used, scratches and knocks can be avoided in some scenarios, extending the appearance and service life of the back cover.

[0079] 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 due to frequent friction contact with the desktop, the support ring or the top part 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 part can be further improved through corresponding surface treatment processes. 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 DLC (Diamond-like Carbon) process to make their surface hardness reach HV and greatly improve their wear resistance.

[0080] See also Figure 9 and Figure 10 , Figure 9 Shows a three-dimensional schematic diagram of a second supporting member of a mobile terminal according to some embodiments of the present disclosure, Figure 10 Shows a three-dimensional schematic diagram of a mobile terminal of some embodiments of the present disclosure when the second support member is removed. 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 the back panel of the terminal, 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 its enlarged radius also enlarges the rotational torque acting on the connecting portion, thereby making the second support member easier to install and disassemble. Furthermore, in some embodiments, the circumferential side surface of the substantially cylindrical support portion may be provided with anti-slip grooves to further facilitate installation and removal by the user. 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 the positioning protrusion formed on the terminal back plate to position the second support member when installing the second support member.

[0081] Those skilled in the art can understand 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 manner between the second support member and the terminal backplane. For example, the connecting portion of the second support member may be a magnetic member such as a magnet. By providing a corresponding magnetic attachment 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, second support members with various different shapes or functions may be provided, and a corresponding magnetic member may be configured for each second support member. The terminal can then identify different accessories by connecting to the different magnetic members. For another example, in some embodiments, the connecting portion of the second support member may be provided with a plug-in member, which may be, for example, matched with a corresponding positioning groove on the terminal backplane by shape matching. Those skilled in the art can understand that, for example, by setting the second support member with various functions to have connecting portions with various different connection types, the terminal can also be set to identify different accessories by its connection manner with the corresponding second support member, and under the control of a corresponding identification control module in the terminal, the terminal can make corresponding reactions after being connected to the second support member. For example: when detecting a second support member including an aroma diffuser box, the time may be recorded starting from the beginning of the connection. For example, after a certain number of days, a prompt may be given that the fragrance agent in the aroma diffuser box has been used up and the fragrance agent needs to be replenished, the fragrance tablet needs to be replaced, and so on. Or, the identification control module of the terminal can match the colors and types of different accessories on the second support member to make the UI become different color styles / themes.

[0082] In some embodiments, a positioning groove may also be provided on the terminal backplane of the mobile terminal. For example, the positioning groove may be provided around the installation position of the second support member on the terminal backplane for positioning the second support member after it is installed. The positioning groove may be generally circular or may be formed into other shapes as long as there is sufficient space in the middle for installing and rotating the second support member. A connection mechanism corresponding to the connection portion is provided at its central portion. For example, when the connection portion is a stud, the connection mechanism may be a corresponding threaded hole. In some embodiments, the terminal body may also include a connection fixing portion corresponding to the connection mechanism for enabling the connection portion of the second support member to be further fixedly connected to the connection fixing portion, so as to be directly fixed to the terminal body. Through this setting, the positioning of the second support member is achieved without adding additional screws or other fixing structures. For example, when the terminal backplane is relatively thin or the weight of the second support member is relatively large, the connection fixing portion can prevent the second support member from falling off or even damaging the terminal backplane due to insufficient fixing force of the connection mechanism. Alternatively, the connection mechanism may also include a portion extending into the terminal body in a direction perpendicular to the surface of the terminal backplane, and this portion provides an additional fixing area for the connection portion of the second support member, thereby enhancing the fixing force. Those skilled in the art can understand that in some other embodiments, the positioning groove may not be provided, and the connection mechanism may be directly provided on the surface of the terminal backplane so that the second support member can be directly fixedly connected to the terminal backplane.

[0083] In some embodiments, a metal inclined surface may be provided on the portion of the bolt of the connection portion adjacent to the end surface of the support portion. At the same time, a corresponding inclined surface is also provided at the entrance of the threaded hole on the terminal backplane. When the user tightens the stud, when the inclined surfaces are in contact with each other, the supporting force between the metals makes it difficult to continue tightening, so that the surfaces of the mobile phone back cover and the support member will not be scratched due to over-tightening. In particular, when the opposite surfaces of the back cover or the support member are plastic parts, excessive deformation and damage caused by their contact are avoided. Thus, further screwing in is prevented, and the situation of damage to the back cover or the support member due to excessive screwing force is avoided. Furthermore, thread damage can be avoided.

[0084] The positioning groove as a whole can be recessed from 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 accidental rubbing of the outer peripheral part of the second support member against other obstacles can be reduced, and on the other hand, the thickness of the second support member perpendicular to the terminal backplane can be ensured, ensuring its structural strength. In addition, by partially accommodating the second support member, the risk of accidentally disconnecting the connection with the terminal backplane due to rotation caused by friction on the circumferential side can also be reduced. In addition, the positioning groove can be at least partially communicated with the outside of the terminal backplane in a direction parallel to the terminal backplane. For example, a break can be provided at at least a part of its circumferential side wall, so that the second support member accommodated therein can be exposed from the break in a direction parallel to the surface of the terminal backplane. In the case where the first support member includes a connecting member formed as a stud, the exposed part of the second support member enables the user to access the side surface of the first support member and perform installation or disassembly operations on it.

[0085] In some embodiments, the supporting part of the first support member can be made of all or part of a transparent or translucent material. The supporting part made of the transparent or translucent material enables the user to conveniently observe the situation inside the positioning groove. For example, when there is a foreign object in the positioning groove or at 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 damage to the corresponding part of the second support member or the terminal backplane. In addition, setting the supporting part of the second support member as a transparent material can also visually reduce the thickness of the second support member and improve the aesthetics. In some embodiments, the supporting part can be set to include a transparent upper half and a non-transparent lower half, where the height of the non-transparent part of the bottom surface is flush with the surface of the terminal backplane, which not only ensures the operability of the second support member but also ensures the consistency in appearance.

[0086] Those skilled in the art can understand that although some embodiments in which the first support member includes two protruding parts are described above, however, on the premise of ensuring 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 backplane are in the same plane, the first support member can also be set to have a single protruding part. For example, the first support member can protrude as a whole, surround the camera module on its outer periphery, and the height of its protruding part exceeds the height of the camera module, so as to form a support ring or a support plane at the top of the first support member. By setting the position of the support ring or the support plane, it can be made to jointly form a two-foot support structure composed of two contact surfaces with the second support member. At this time, as long as the center of gravity of the terminal when placed falls within the overall projected area of the support structure, the terminal can still remain stable when placed.

[0087] See Figure 11 ,Figure 11 A three-dimensional schematic diagram of a mobile terminal showing some embodiments of the present disclosure is shown. In some embodiments, the mobile terminal may further include additional connection fixing members. For example, the connection fixing member may be a terminal lanyard fixedly connected to the back panel of the terminal, and both ends thereof are 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.

[0088] See Figure 12 and Figure 13 , Figure 12 A three-dimensional schematic diagram of a mobile terminal showing some embodiments of the present disclosure Figure 13 A schematic diagram of a variant state of the embodiment shown in the figure is shown. In some embodiments, a movable support member may be further 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 a protruding portion of the second support member. The support frame may be, for example, generally in the shape of a long strip plate, and one end along its length direction is hingedly connected to the surface of the second support member by means of a hinge device, so that the entire support frame can pivot around the hinge axis of the hinge device. In some embodiments, the hinge axis of the hinge device may be arranged parallel to the length direction of the terminal. In this case, when the entire support frame pivots around the hinge axis in a direction away from the terminal and unfolds, 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 by means of the support of the support frame and the bottom edge of the terminal. Those skilled in the art can understand that although the embodiment in which the bottom side of the support frame is set to be parallel to the bottom side of the terminal is described above, the present disclosure does not limit the specific setting manner of the support frame. For example, the hinge device may be set at a certain inclination angle with respect to the length direction of the terminal, so that the support frame can unfold at an inclination angle, so that the terminal has a certain elevation angle when standing, or the inclination angle of the hinge device with respect to the terminal may be set to be adjustable according to needs.

[0089] See Figure 14 , Figure 14A perspective view of a mobile terminal showing some embodiments of the present disclosure is presented. A solution with another movable support member in some embodiments of the present disclosure is shown. In this embodiment, the second support member is provided with a fixing groove that is recessed inward along the circumference of its support portion. The movable support member includes a fixing ring that is generally elliptical in shape and 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 snap connection manner. With 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 fixing latch, a wristband, etc., so that the terminal can be connected or supported on other supports in an unrestricted manner.

[0090] See Figure 15 , Figure 15 A perspective view of a mobile terminal showing some embodiments of the present disclosure is presented. In some embodiments, the second support member may further include a receiving portion. The receiving portion may be, for example, a card case fixedly connected to the support portion of the second support member. The card case may be generally in the shape of a flat box, fixedly connected to the second support member at one corner, and may be fixedly connected to the terminal back plate at the other three corners by means of mechanisms such as screws. The interior of the card case may include a receiving cavity for receiving cards, change, etc. In some embodiments, the height of the card case perpendicular to the plane of the terminal back plate may be flush with the height of the second support member, so that this plane of the card case and the second support member can jointly support the terminal, thereby further enhancing the stability of the terminal when placed.

[0091] See Figure 16 , Figure 16 A perspective view of a mobile terminal showing some embodiments of the present disclosure is presented. In some embodiments, the second support member is provided with a hollow structure, and an accommodation cavity is defined inside it. The accommodation cavity can be used to accommodate fragrance agents such as solid spices, so as to provide a fragrance effect for the user as an aromatherapy box 500 during use. In some embodiments, the accommodation cavity can communicate with 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 fragrance substances to the outside.

[0092] In addition, in some embodiments, since the screw / connection structure is metal, an electronic component module can be included in the second support member, and the sensor can be electrically connected to the identification control module of the terminal through connection structures such as screws. For example, in some embodiments, a pressure sensor is provided on the outer surface of the second support member to pick up a pressing signal and then issue a control instruction to the terminal.

[0093] In some embodiments, physical buttons may also be provided on the supporting portion of the second support member. For example, at the same time, the protruding portion of the second support member is made into a button with a certain damping effect.

[0094] In some embodiments, in addition, buttons may also be provided on the protruding side surface of the supporting portion of the second support member, the surface close to the side surface of the mobile phone, etc. When pressed, it can be pressed in the direction of the rotation axis of the supporting portion. By making corresponding settings for the recognition control module of the terminal, after the terminal detects the second support member including the corresponding accessories, it can activate different button functions in response to the pressing of the corresponding buttons. For example, when playing a game, pressing the button on the second support portion can perform customization of specific effects; or as a quick switch, associating the button gesture with the control instructions of the music player software to control the playback state of the music. For example, pressing once controls play / pause, pressing twice controls skipping to the next song, pressing three times controls skipping to the previous song, and long pressing switches 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, this button can be used as a touch switch for starting or turning off the light strip.

[0095] It can be understood that the electronic components of the button may also include a touch sensor, so that in addition to the above embodiments, more gestures can be recognized, such as swiping, multi-finger operations, etc.

[0096] A display screen may also be provided to provide more interactive effects.

[0097] In some embodiments, the present disclosure also provides a mobile terminal, which includes: a mobile terminal body, on which an installation groove is provided; a locking member, detachably connected to the installation groove; a rear cover, on which an assembly position corresponding to the installation groove is provided, and the locking member passes through the assembly position and the installation groove in sequence to fix the rear cover on the mobile terminal body; at least one locking member is fixedly connected to the accessory assembly at the end far from the rear cover, wherein at least a part of the accessory assembly protrudes from the surface of the rear cover.

[0102] In some embodiments, sensors are provided on the mobile terminal for detecting the status information of N accessory components.

[0103] In some embodiments, the sensor is a Hall element, and magnetic members with different magnetic fluxes are provided on the N accessory components. The Hall element identifies different accessories according to the information of the magnetic members.

[0104] In some embodiments, a plurality of mounting grooves for fixing the second accessory component are provided on the mobile terminal. The second accessory includes a bottom plate abutting against the rear cover and a cover plate covering above the bottom plate and magnetically connected to it.

[0105] In some embodiments, the inner side wall of the mounting groove has internal threads, and the locking member has external threads. The locking member is threadedly connected to the mounting groove to fix the accessory component to the mobile terminal.

[0106] In some embodiments, the accessory component 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 of which is fixedly connected to the locking member, and the rotating part is rotatably connected to the connecting part along the axis.

[0107] In some embodiments, the other end of the accessory body is also connected with a locking member for detachably connecting the other end of the accessory body to the mobile terminal through the mounting groove.

[0108] In some embodiments, the accessory body is a lanyard body 201. Both ends of the lanyard body are fixedly connected to two rotating parts, and the lanyard body is rotatably connected to the connecting part through the rotating parts.

[0109] In some embodiments, the locking member is a stud. One end of the connecting part is connected to the rotating part and the other end is connected to the stud. The inner side wall of the mounting groove has internal threads, and two studs are respectively connected to the mounting groove to fix the lanyard body to the mobile terminal.

[0110] In some embodiments, the connecting part is a bent pipe, which includes a first straight pipe section, a bent section and a second straight pipe section connected in sequence. In the assembled state, the first straight pipe section is arranged perpendicular to the rear cover of the mobile terminal and fixedly connected to the stud. The second straight pipe section is arranged parallel to the rear cover of the mobile terminal and connected to the lanyard body.

[0111] In some embodiments, the rotating part includes a fastening ring and a fixing ring. The fastening ring is sleeved on the end of the lanyard body and fixedly connected to the lanyard body. The fixing ring is sleeved on the outer periphery of the fastening ring and the two are fixedly connected. The end of the fixing ring away from the lanyard body is connected to the second straight pipe section.

[0112] In some embodiments, the rotating part is detachably connected to the second straight pipe section, and / or the fixing ring can rotate circumferentially along the second straight pipe section.

[0114] In some embodiments, the height by which the side of the fixing ring away from the rear cover surface protrudes from the rear cover surface is the same as the height by which the camera decorative part protrudes from the rear cover surface.

[0115] In some embodiments, the accessory assembly is a bracket, and the bracket includes: a turntable assembly, which includes an upper turntable and a lower turntable, wherein the upper turntable and the lower turntable are respectively provided with through holes for the two to rotate relative to each other along a first rotation axis and for a locking member to pass through; a support assembly, which is used to be connected to the upper surface of the upper turntable through a rotating shaft and to change the angle with the upper turntable by rotating along a second rotating shaft. When the bracket is installed on the rear cover of the mobile terminal, it can provide support for the mobile terminal at multiple angles.

[0116] See Figures 17 to 19 , wherein, Figure 17 shows a rear view schematic diagram of a mobile terminal according to some embodiments of the present disclosure, Figure 18 shows a three-dimensional schematic diagram of a mobile terminal according to some embodiments of the present disclosure, Figure 19 shows a side view schematic diagram of an accessory assembly of a mobile terminal according to some embodiments of the present disclosure. The mobile terminal includes a mobile terminal body, on which an installation groove is provided; a locking member, which is detachably connected to the installation groove; a rear cover, on which an assembly position corresponding to the installation groove is provided. The locking member passes through the assembly position and the installation groove in sequence to fix the rear cover on the mobile terminal body; at least one locking member is fixedly connected to the accessory assembly at the end away from the rear cover, wherein at least part of the accessory assembly protrudes from the rear cover surface.

[0117] The mobile terminal in the present disclosure includes a mobile terminal body, a locking member and a rear cover. Among them, an installation groove is provided on the mobile terminal body, and an assembly position corresponding to the installation groove is provided on the rear cover. During installation, the locking member passes through the assembly position on the rear cover and is inserted into the installation groove for fixation, so as to fix the rear cover on the mobile terminal body.

[0118] An accessory component is also installed on the locking member in this disclosure. The accessory component can be installed on the mobile terminal through the locking member. After the locking member is assembled, at least a part of the accessory component protrudes from the surface of the rear cover. Specifically, the accessory component is fixedly connected to one end of the locking member away from the rear cover. Since the locking member is detachably connected to the installation groove, the accessory component can also be removed from the mobile terminal for replacement and other operations.

[0119] In the solution provided by this disclosure, while the locking member fastens the rear cover and the mobile terminal body, it can also install the accessory component on the mobile terminal, avoiding the need for an additional installation structure to fix the accessory component to the mobile terminal, and this solution can save costs.

[0120] In the above solution, the inner side wall of the installation groove has internal threads, the locking member has external threads, and one end of the locking member passes through the assembly position on the rear cover and is threadedly connected to the installation groove, thereby fixing the accessory component to the mobile terminal.

[0121] The solution of this embodiment further includes: the mobile terminal further includes a camera decorative member protruding from the surface of the rear cover. The rear cover is placed downward on a plane, and the accessory component and the camera decorative member contact the plane to support the mobile terminal, so that the rear cover is suspended above the plane.

[0122] A camera decorative member is also provided on the mobile terminal in this disclosure. Due to factors such as lens combination or focal length requirements, the camera decorative member often has a relatively large thickness, which makes it inevitably protrude from the surface of the rear cover of the mobile terminal. Since the accessory component also protrudes from the surface of the rear cover, when the mobile terminal is placed on a plane, the accessory component and the camera decorative member contact the plane to support the mobile terminal, so that the rear cover is suspended above the plane, thereby avoiding the rear cover being scratched or worn due to rubbing.

[0123] The solution of this embodiment further includes: N accessory components are provided on the mobile terminal, where N is a positive integer greater than or equal to; the assembly position at least includes a first assembly position and a second assembly position. The first accessory component has an extended length and has two ends, and 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 member.

[0124] In a specific implementation, multiple accessory components with different functions can be installed on the mobile terminal, such as an aromatherapy box, a bracket, a lanyard, etc. Different accessory components can be installed on the mobile terminal separately, or two or three accessory components can be installed on the mobile terminal simultaneously.

[0125] In this solution, the accessory component includes a first accessory component. The first accessory component has an extended length and two ends. The two ends of the first accessory component are connected to two locking members, thereby fixedly installing the first accessory component on the mobile terminal. The number of the installation slots, the assembly positions, and the locking members is the same. In this solution, since the two ends of the first accessory component are fixed to the mobile terminal, two installation slots need to be provided on the mobile terminal body, namely the first installation slot and the second installation slot. Two assembly positions are also correspondingly provided on the rear cover, namely the first assembly position and the second assembly position. The two locking members are respectively fixedly connected to the first installation slot and the second installation slot through the first assembly position and the second assembly position, thereby installing the two ends of the first accessory component on the mobile terminal. The camera decorative member is usually arranged at the upper left corner of the mobile terminal. The two ends of the first accessory component are respectively arranged at the left and right ends of the mobile terminal, so that the center of gravity of the mobile terminal is located between the connection line of the first assembly position and the second assembly position and the center of the camera decorative member.

[0126] The solution of this embodiment further includes: there is also a second accessory component provided on the surface of the protrusion on the rear cover. The rear cover is placed downward 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 rear cover is suspended above the plane.

[0127] In a specific solution of this embodiment, not only a first accessory component is provided on the mobile terminal, but also a second accessory component different from the first accessory component is provided, and at least part of the second accessory component protrudes from the surface of the rear cover. Since both the first accessory component and the second accessory component protrude from the surface of the rear cover, when the mobile terminal is placed on a placement plane such as a desktop, the rear cover of the mobile terminal will be spaced from the placement plane by the support of the first accessory component and the second accessory component, thereby avoiding being scratched or worn due to rubbing.

[0128] In the above solution, the first accessory component can be a support structure that only provides support for the first support member, and the second accessory component can be a card case. The card case includes a bottom plate that abuts against the back cover of the mobile terminal, and a card case body that is arranged above the bottom plate and magnetically connected to it. The card case body has an accommodation cavity inside for accommodating cards, change, etc. The card case can be roughly in the shape of a flat box, for example. 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 mechanisms such as screws. In some embodiments, the height of the card case 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 this plane of the card case and the first support component can jointly support the mobile terminal, thereby further improving the stability of the mobile terminal when placed. In some embodiments, the card case body can also have a variety of different sizes and structures, so as to be able to accommodate different contents according to different usage needs. A magnetic attraction mechanism corresponding to the magnetic attraction member on the bottom plate is provided on each card case body, so that it can be disassembled, assembled and replaced conveniently when needed.

[0129] The solution of this embodiment further includes: a sensor is arranged on the mobile terminal for detecting the status information of N accessory components. The sensor is a Hall element, and magnetic members with different magnetic fluxes are arranged on the N accessory components. The Hall element identifies different accessories according to the information of the magnetic members.

[0130] The solution of this embodiment further includes: the accessory component 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 of which is fixedly connected to a locking member, and the rotating part is rotatably connected to the connecting part along the axis.

[0131] In the above solution, the accessory component includes an accessory body, a rotating part and a connecting part that are connected in sequence. Among them, the connecting part is fixedly connected to one end of the locking member. The accessory body is fixed on the mobile terminal through 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.

[0132] In this disclosure, the locking member is a stud. The outer surface of the stud has an external thread, and the inner side wall of the installation groove has an internal thread. The stud passes through the back cover and is threadedly connected to the installation groove on the mobile terminal, thereby fixing the accessory body to the mobile terminal.

[0133] As Figure 19 -21 shows, Figure 20 shows a cross-sectional schematic view of an accessory component of a mobile terminal according to some embodiments of this disclosure, Figure 21 shows Figure 20An enlarged schematic view of part A. In a specific embodiment, the accessory body is the 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 convex structure is provided at the end of the lanyard body. The rotating part includes a fastening ring and a fixing ring. The fastening ring is a tubular structure with a certain extension length and both ends open, and its inner surface has a ring-shaped limiting part protruding towards the axis of the fastening ring. The lanyard body is injection-molded together with the fastening ring, and the convex structure at the end of the lanyard body is snap-fitted and limited with the limiting part. In this solution, the fixing ring is also a tubular structure with a certain extension length and both ends open. The extension length of the fixing ring is greater than that of the fastening ring, and the diameter of the cross-section of the fixing ring is also greater than the diameter of the cross-section of the fastening ring. After the end of the lanyard body is fixedly connected to the fastening ring, the fastening ring is inserted into the fixing ring and the two are injection-molded and connected.

[0134] In an alternative solution of this embodiment, the height by which the side of the fixing ring away from the back cover surface protrudes from the back cover surface is the same as the height by which the camera decoration protrudes from the back 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 form a triangle. When the mobile terminal is placed on a plane, the back cover does not abut against the plane, avoiding scratching and damage to the back cover.

[0135] In this solution, the connecting part is a bent pipe formed integrally. The bent pipe includes a first straight pipe section, a bent section, and a second straight pipe section connected in sequence. In the assembled state, the first straight pipe section is arranged perpendicular to the back cover of the mobile terminal and fixedly connected to the stud, and the second straight pipe section is arranged parallel to the back cover of the mobile terminal and connected to the fixing ring connecting the end of the lanyard body.

[0136] The fixing ring and the second straight pipe section are detachably connected by a plug-and-play method. Specifically, one end of the second straight pipe section away from the bent section has a first diameter section and a second diameter section. The diameter of the first diameter section is smaller than that of the second diameter section. And the diameters of both the first diameter section and the second diameter section are smaller than the diameter of the cross-section of the fixing ring. One side of the fixing ring away from the end of the lanyard body has a first convex structure protruding circumferentially along its inner side wall. The first diameter section has a second convex structure protruding circumferentially along its outer side wall, and there is a certain length of interval between the second convex structure and the second diameter section. During installation, under an external force, the first convex structure is inserted into the interval between the second convex structure and the second diameter section, so that the rotating part can be rotatably connected to the connecting part along its axis.

[0137] Since the end of the lanyard body needs to be injection-molded and connected to the rotating part, the end of the lanyard body is connected to the rotating part, and the whole is regarded as a standard part. The lanyard body can be connected to the mobile terminal at only one end, or both ends can be connected to the mobile terminal. When both ends of the lanyard body are connected to the mobile terminal, after connecting the two connecting parts to the mobile terminal, the two ends of the lanyard body are rotatably connected to the connecting parts through the rotating parts. Or after one end of the lanyard body is connected to the connecting part, the connecting part fixes one end of the lanyard body on the mobile terminal through screws, and after the other connecting part is also rotatably fixed on the mobile terminal, the other end of the lanyard body is connected to the connecting part through the rotating part.

[0138] 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, the rear cover can still be fixed on the mobile terminal body.

[0139] In a specific embodiment, the lanyard body is made of a flexible material and has an elastic deformation amount. When both ends of it are fixed on both sides of the mobile terminal, the lanyard body is attached to the rear cover of the mobile terminal. When the user uses it, the finger penetrates between the lanyard body and the rear cover, so as to fix the mobile terminal on the user's hand.

[0140] Such as Figure 22 shown, Figure 22 shows a perspective schematic diagram of a mobile terminal according to some embodiments of the present disclosure. In another embodiment of this embodiment, the accessory component is a bracket.

[0141] Also refer to Figures 23 to 26 , Figure 23 shows a side view schematic diagram of the accessory component of the mobile terminal according to some embodiments of the present disclosure; Figure 24 shows a perspective schematic diagram of the accessory component of the mobile terminal according to some embodiments of the present disclosure; Figure 25 shows a perspective schematic diagram of the turntable component of the mobile terminal according to some embodiments of the present disclosure, Figure 26A three-dimensional schematic diagram of the turntable assembly of a mobile terminal showing some embodiments of the present disclosure is presented. In this solution, the bracket includes a turntable assembly, a stud, and a support assembly. Among them, 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 oppositely. Through holes that rotate relative to each other along the first rotation axis are respectively provided in the middle regions of the upper turntable and the lower turntable. After the stud passes through the through holes of the upper turntable and the lower turntable in sequence, the rear cover is fixed to the mobile terminal by cooperating with the assembly position on the rear cover. At the same time, the stud also fixes the turntable assembly to the rear cover of the mobile terminal. Among them, the stud is fixedly connected to the lower turntable and is rotatably connected to the upper turntable relatively. The support assembly is connected to the upper surface of the upper turntable through a rotating shaft and changes the included angle with the upper turntable by rotating along the second rotating shaft. When the bracket is installed on the rear cover of the mobile terminal, it can provide support at multiple angles to the mobile terminal.

[0142] 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 arranged in the groove structure. The upper turntable is an open trough-like structure, and the inner surface of the upper turntable has a protruding sliding portion. When the upper turntable and the lower turntable are assembled, the side wall of the upper turntable covers 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.

[0143] The support assembly includes an upper support plate, a lower support plate, and a metal member 303 arranged between the two. The metal member is in a plate-like structure, one end of which is fixedly connected to the lower support plate. The other end is interference-wound around the second rotating shaft at the second rotating shaft to form a second rotating shaft rotating portion. The upper support plate has a certain thickness, and a sunken area is provided on its lower surface. The lower support plate fixed with the metal member is fixed in the sunken area of the upper support plate by injection molding, and the surface of the upper support plate after injection molding is a planar structure.

[0144] An installation portion 304 protruding above its upper surface is provided on the upper turntable. Among them, the installation portion includes side walls arranged oppositely on one side of the through hole, and fixing holes arranged oppositely are provided on the two side walls. An installation hole is provided on the second rotating shaft rotating portion of the metal member, and the installation hole is arranged between the two fixing holes. The second rotating shaft passes through the installation hole and the two fixing holes to rotatably connect the turntable assembly 301 and the support plate assembly 302.

[0145] In this solution, when installing the bracket on the mobile terminal, there are two operation methods. One is to insert the lower end of the stud through the assembly part into the installation groove on the mobile terminal body, and then rotate the lower turntable 3012 to fix the bracket on the mobile terminal. The other method is to insert the lower end of the stud through the assembly part into the installation groove on the mobile terminal body, and then rotate the support assembly. At this time, if the sliding part is not in contact with the stopper, the sliding part slides in the groove structure, and the support assembly drives the upper turntable to rotate while the lower turntable does not rotate. When the sliding part slides to the position of the stopper and contacts the stopper, continue to rotate the upper turntable in the same direction. At this time, the upper turntable and the lower turntable together drive the stud to rotate, so that the screw is threadedly connected to the installation groove.

[0146] Those skilled in the art can understand that although the above describes embodiments of using the assembly part to fix the lanyard or the 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 be made to correspond to one or more of the plurality of assembly parts, so that the assembly component can be connected to the back of the mobile terminal by means of connecting pieces such as bolts. At the same time, according to the actual use situation, the assembly component can be flexibly arranged at the corresponding positions of some of the plurality of assembly parts, further enriching the types of its uses.

[0147] In a specific solution of this embodiment, the stopper has a certain extension width in the groove, making the groove structure an unclosed ring not greater than ° around the first rotation axis. That is, the angle at which the sliding part slides along the first rotation axis in the groove structure does not exceed °.

[0148] In an optional implementation manner, the relative rotation angle between the upper turntable and the lower turntable is not less than °. That is to say, 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's direct contact with the mobile terminal and affecting the user experience.

[0149] In an optional implementation scheme of this embodiment, the rotation angle of the support assembly along the second rotation axis is greater than ° and less than °. In this scheme, since a vertical placement of less than ° is not sufficient to support the mobile terminal, and if it is greater than °, the support strength for the mobile terminal will decrease. Therefore, the rotation angle of the support assembly is set between ° and.

[0150] 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.

[0151] 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. At this time, 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.

[0152] See also Figures 27 to 30 , where Figure 27 Shows a three-dimensional schematic diagram of an accessory assembly of a mobile terminal of some embodiments of the present disclosure; Figure 28 Shows a three-dimensional schematic diagram of a base of an accessory assembly of a mobile terminal of some embodiments of the present disclosure; Figure 29 Shows a three-dimensional schematic diagram of the combined state of the base and the mounting base of the mobile terminal of some embodiments of the present disclosure; Figure 30 Shows a three-dimensional schematic diagram of the cover of the accessory assembly of the mobile terminal of some embodiments of the present disclosure. In a specific solution of this embodiment, the accessory assembly is an aromatherapy box.

[0153] The aromatherapy box includes a base 501, a mounting seat 502 and a cover 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. The diameter of the mounting hole is larger than the diameter of the fixed section, thereby forming an avoidance area for the fixed section.

[0154] The cover of the aromatherapy box is a plate-like structure with a through hole in the middle. At the through hole, there is a fastener that cooperates with the fixed section on the locking member. On the outer periphery of the fastener, there are two claw structures, and the two claw structures are respectively arranged corresponding to the two fixing grooves on the mounting seat. The claw structure includes a first claw and a second claw. The outer side wall of the first claw abuts against the inner side 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 outer periphery of the fixed section, and the two claws abut against the fixed seat, so that the cover is fixed on the mounting seat.

[0155] In the present disclosure, on the peripheral wall of the base of the aromatherapy box, there are a plurality of extending portions, and the plurality of extending portions are arranged at intervals. When the cover is fixed to the mounting seat, the lower surface of the cover abuts against the upper ends of the plurality of extending portions, so that a hollow area is formed between the plurality of extending portions, providing a diffusion channel for the aromatherapy inside the aromatherapy box.

[0156] During use, an aromatherapy tablet or other solid-form aromatherapy material is loaded into the aromatherapy box, the cover is installed, and then the aromatherapy box is fixed to the mobile terminal through the cooperation of the locking member and the installation groove.

[0157] In addition, in some embodiments, the present disclosure also provides a protective case for a terminal. The protective case can, for example, be independent of the mobile terminal body and be detachably installed 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 plane of the back of the protective case. On the mobile phone protective case, there is a positioning groove for installing the second support member, and the second support member is detachably arranged in the positioning groove

[0158] Those skilled in the art can understand that the various second support members described in the above-mentioned multiple embodiments can all be used in cooperation with the same or similar terminals in the form of independent backplate accessories. That is, each backplate accessory includes the same or similar connecting portions and can be correspondingly installed with the corresponding connecting mechanisms on the backplate of the corresponding terminal. Thus, a variety of backplate accessories can be interchanged on the same terminal according to different needs, enabling users to select the actual accessories they need according to the actual use scenarios, greatly enhancing the expandability of the terminal functions.

[0159] By providing the first support member and the detachable second support member, the mobile terminals in some embodiments of the present disclosure can avoid the direct contact between the backplate of the terminal and the placement plane, and can also avoid the situation where the terminal cannot be placed flat due to the protruding part of the camera module, resulting in additional wear of the contact part when it contacts the placement plane in an inclined posture. Further, by setting the second support member as a separately replaceable backplate accessory, it can be replaced more flexibly and conveniently when wear occurs, and provides a more flexible choice for customers. Also refer to Figure 31 , Figure 31A perspective schematic diagram of a mobile device showing some embodiments of the present disclosure is presented. In some embodiments, some mobile devices 200 according to the present disclosure may include an antenna module 100 according to some embodiments of the present disclosure, and a mobile device main body 300 connected to the antenna module 100.
