[0064] 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. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. 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.

[0065] 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.

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.

[0067] 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.

[0068] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0069] The present disclosure provides a mobile terminal, which includes a mobile terminal body and a back cover, which are fixed together by a locking member. An accessory assembly is also installed on the locking member, so that when the locking member fixes the back cover and the mobile terminal body, the accessory assembly can be installed on the mobile terminal, without the need to set up an additional fixing device, thereby saving costs.

[0070] like Figure 1 As shown, the mobile terminal 100 includes a mobile terminal body 101; a back cover 102, on which an assembly position 106 is arranged; at least one locking member, which is detachably connected to the assembly position, wherein when the locking member is installed in the assembly position, the locking member fixes the back cover to the mobile terminal body; and an accessory component, which is connected to the at least one locking member at one end away from the back cover, and when the mobile terminal body and the back cover are in an assembled state, the accessory component is fixedly connected to the mobile terminal body through the locking member.

[0071] The mobile terminal 100 in the present disclosure includes a mobile terminal body, a locking member 107 and a back cover 102. The back cover 102 is provided with an assembly position 106. During installation, the locking member 107 passes through the assembly position 106 on the back cover 102 to fix the back cover 102 on the mobile terminal body.

[0072] The locking member 107 in the present disclosure is also equipped with an accessory component, and the accessory component can be installed on the mobile terminal 100 through the locking member 107. When the locking member 107 is assembled, the accessory component at least partially protrudes from the surface of the back cover 102. Specifically, the accessory component is fixedly connected to the end of the locking member 107 away from the back cover 102. Since the locking member 107 is detachably connected to the mounting slot, the accessory component can also be removed from the mobile terminal 100 for replacement and other operations.

[0073] The accessory component in this solution can be a supporting component that only provides supporting force for the mobile terminal, or can be a structure with other functions.

[0074] In the solution provided by the present disclosure, the locking member 107 can not only fasten the back cover 102 and the mobile terminal body, but also install the accessory component on the mobile terminal 100, avoiding the need for an additional mounting structure to fix the accessory component to the mobile terminal 100. This solution can save costs.

[0075] In a specific solution, a mounting groove is provided on the mobile terminal body corresponding to at least one assembly position, and the mounting groove is formed by the surface of the terminal body abutting against the back cover being recessed in a direction away from the back cover. Specifically, the locking member 107 is a stud having an external thread, the inner side wall of the mounting groove has an internal thread, and the assembly position 106 is a through hole provided on the back cover. One end of the locking member 107 passes through the assembly position 106 on the back cover 102 and is threadedly connected to the mounting groove, thereby fixing the accessory assembly to the mobile terminal 100.

[0076] In a specific implementation of this embodiment, the accessory assembly is fixedly connected to the locking member and is an integral part. In this case, a plurality of decorative studs are provided for the mobile terminal, so that when the user does not need to install the accessory assembly on the mobile terminal, the accessory assembly is directly removed, and then the mobile terminal body and the back cover are fixed with the matching decorative studs. Since the appearance of the decorative studs is more beautiful than that of ordinary studs, they are more likely to be favored by users, thereby improving the user experience.

[0077] In another specific implementation of this embodiment, the accessory component is detachably connected to the locking member. When the user wants to install the accessory component, the accessory component is installed on the stud, and then the stud is passed through the assembly position 106 on the back cover and the installation slot on the mobile terminal body, so that the three are fixed together. When the user does not want to install the accessory component, the accessory component only needs to be removed from the stud. Of course, in this solution, the stud can also be a decorative stud.

[0078] In a specific embodiment: the mobile terminal 100 in the present disclosure is also provided with a camera module decoration 103. Due to factors such as lens combination or focal length requirements, the camera module decoration 103 often has a large thickness, which makes it inevitable that it protrudes from the surface of the back cover 102 of the mobile terminal 100. Since the accessory component is also provided protruding from the surface of the back cover 102, when the mobile terminal 100 is placed on a plane, the accessory component and the camera module decoration 103 contact the plane to support the mobile terminal 100, so that the back cover 102 is suspended above the plane, thereby preventing the back cover 102 from being scratched or rubbed, resulting in scratches or wear.

[0079] refer to Figure 1 and Figure 2As shown, the back cover 102 in the present disclosure may be, for example, roughly rectangular, with a camera module decoration 103 disposed at the corner thereof, the camera module decoration 103 protruding from the back cover 102 in a direction perpendicular to the plate surface of the back cover 102. At the same time, at least one accessory component is also disposed on the back cover 102, which is detachably disposed relative to the back cover 102, and which also protrudes perpendicularly to the plane of the back cover 102 to support the terminal body 101. By means of the camera module decoration 103 and the accessory component protruding perpendicularly to the back cover 102, when the terminal is placed on a placement plane such as a desktop, the back cover 102 will be spaced from the placement plane by means of the support and barrier of the camera module decoration 103 and the accessory component, thereby avoiding being scratched and rubbed, resulting in scratches or wear.

[0080] Specifically, in some embodiments, the camera module decoration of the mobile terminal includes a first camera module 1031 and a second camera module 1032, wherein the first camera module 1031 may include, for example, a main lens and related components thereof, and the second camera module 1032 may include, for example, a secondary lens and / or other camera-related components such as a flash. The first camera module 1031 and the second camera module 1032 are arranged at intervals from each other. At the same time, the camera module decoration 103 may include two protrusions, i.e., two support rings protruding perpendicularly to the plane of the rear cover 102. The first support ring 1033 may surround the outer periphery of the protruding portion of the first camera module 1031, and the second support ring 1034 surrounds the outer periphery of the protruding portion of the second camera module 1032, and the top of the protruding portion of the first support ring 1033 and the second support ring 1034 exceeds the height of the first camera module 1031 and the second camera module 1032 along the vertical direction of the rear cover 102.

[0081] Multiple accessory components can be set on the mobile terminal, and the types of the multiple accessory components can be the same or different. When an accessory component is installed, the accessory component is arranged on the second corner 105 of the back cover 102 opposite to the first corner 104, and the relative here means that the second corner 105 is the diagonal angle of the first corner 104. When multiple accessory components are installed, at least one accessory component is arranged at the second corner 105. Among them, the camera module decoration 103 can, for example, include an outer edge shape that is the same or similar to the shape of the first corner 104 of the back cover 102, and the accessory component can, for example, also include an outer edge shape that is the same or similar to the shape of the second corner 105 of the back cover 102, so as to align with the outer periphery of the back cover 102 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 camera module decoration 103 and the accessory component, and it can be selected to be formed into other shapes according to actual application conditions.

[0082] When the rear cover 102 is placed downward on a placement plane such as a desktop, the first support ring 1033 and the second support ring 1034 are beyond the first camera module 1031 and the second camera module 1032 in a direction perpendicular to the plane of the rear cover 102, so they can replace the first camera module 1031 and the second camera module 1032 to contact the placement plane, so that its lens or related exposed optical device parts will not directly contact the placement plane. In addition, when the rear cover 102 is placed downward, the accessory component also contacts the placement plane, so that it and the first support ring 1033 and the second support ring 1034 can form a three-point support structure. And because it and the first support ring 1033 and the second support ring 1034 are respectively arranged at the first corner 104 and the second corner 105 opposite to each other, when the terminal is placed flat, the center of gravity of the terminal body 101 must fall within the triangular support area formed by the three points in a direction perpendicular to the surface of the rear cover. Therefore, when the terminal is placed flat, it can be ensured that it will not be deflected due to its own weight, resulting in the back cover 102 or the side of the back cover 102 contacting the placement plane. In addition, in some embodiments, the distal ends of the first support ring 1033 and the second support ring 1034 protruding from the plane of the back cover 102 can be flush with the distal end of the accessory component protruding from the plane of the back cover 102, so that when the back cover 102 is placed downward, the planes at the tops of the three corresponding to the first support ring 1033, the second support ring 1034, and the distal end of the accessory component can contact the placement plane as a whole, thereby increasing the contact area to distribute the terminal's own weight and the impact of taking and placing, so that the contact parts of the three with the placement plane are 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 back cover is 0.5mm, so that the structural selection of the camera module decorative part 103 and the accessory component has a higher degree of freedom.

[0083] The common lens assembly currently often includes an outer surface made of a sapphire glass surface. By setting a support ring protruding perpendicular to the surface of the back cover 102, 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 camera module decorative piece 103 and other surfaces of the back cover near the first corner from being scratched and damaged.

[0084] In this way, even if the back cover is made of materials such as plastic, leather, etc. 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.

[0085] It will be appreciated by those skilled in the art that, in an embodiment in which the first support ring 1033 and the second support ring 1034 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 1033 and the second support ring 1034 can be made of stainless steel as the main material, and their surfaces can be treated with a DLC (Diamond-like Carbon) process to achieve a surface hardness of 650HV and greatly improve their wear resistance.

[0086] It is understood by those skilled in the art that, although some embodiments of the camera module decoration of the present disclosure including two protrusions are described above, the camera module decoration may also be configured to have a single protrusion, provided that the distal ends of the camera module decoration and the accessory assembly protruding in a direction perpendicular to the plane of the rear cover 102 are in the same plane. For example, the camera module decoration 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 camera module decoration. 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 accessory assembly. At this time, as long as the center of gravity of the terminal falls within the overall projection area of ​​the support structure when it is placed, the terminal can still remain stable when placed.

[0087] See also Figure 3 and Figure 4 , Figure 3 A three-dimensional schematic diagram showing an accessory assembly of a mobile terminal according to some embodiments of the present disclosure is shown. Figure 4 A three-dimensional schematic diagram of a mobile terminal of some embodiments of the present disclosure when an accessory component is removed is shown. The accessory component includes an accessory body and a locking member. Specifically, the accessory body is a support member 107, and the thickness of the support member 107 along the extension direction of the locking member is greater than 1 mm and less than 15 mm. This thickness of the accessory body can ensure that it can protrude from the back surface of the terminal, and can also prevent it from protruding too much from the back cover so that the other end of the mobile terminal collides with a flat surface such as a desktop.

[0088] The locking member 107 may be, for example, a connecting member such as a stud for connecting with the rear cover 102, and the supporting member 107 may be, for example, fixedly connected to one end of the locking member 107. In some embodiments, the locking member 107 is a stud, and the supporting member 107 may be substantially cylindrical, and the supporting member 107 and the stud are coaxially arranged and fixedly connected relative to each other.

[0089] In the solution disclosed herein, when the mobile terminal is placed on a flat surface, the back cover 102 will be separated from the placement plane by the support of the camera module decoration 103 and the accessory components, thereby avoiding scratches or wear on the back cover due to friction.

[0090] In a specific implementation of this embodiment, the terminal body and the back cover are fixed together by an accessory assembly. Specifically, the back cover has an assembly position that runs through it, the terminal body has an installation groove that is arranged corresponding to the assembly position on the back cover, and the accessory assembly has a locking piece with a certain extension length. During installation, the locking piece passes through the assembly position and is fixed to the installation groove in sequence, thereby fixing the terminal body and the back cover. More specifically, the inner side wall of the installation groove has an internal thread, the locking piece has an external thread, and the locking piece is threadedly connected to the installation groove. This assembly method enables the accessory assembly and the assembly position to be detachably connected, that is, the locking piece on the accessory assembly is detachably connected to the assembly position.

[0091] In the above solution, the accessory component has a variety of different structures. In addition to supporting the rear cover away from the plane as an auxiliary camera module decorative part, it can also have other functions. For example, the accessory component can be a mobile terminal stand, providing support for the mobile terminal so that it can stand upright or be placed on a horizontal object at an angle. Therefore, in the above solution, not only can the accessory component be fixed on the mobile terminal, but also the rear cover and the terminal body can be fixed together.

[0092] In the solution provided by the present disclosure, the locking member 107 can not only fasten the back cover 101 and the terminal body, but also install the accessory component on the mobile terminal 100, avoiding the need for an additional mounting structure to fix the accessory component to the mobile terminal 100. This solution can save costs.

[0093] In the above solution, the locking member 107 is a stud with an external thread, the inner side wall of the mounting groove has an internal thread, and the assembly position 106 is a through hole provided on the back cover. One end of the locking member 107 passes through the assembly position 106 on the back cover 101 and is threadedly connected to the mounting groove, thereby fixing the accessory assembly to the mobile terminal 100.

[0094] In a specific implementation of this embodiment, the support member 107 and the stud are formed by an integral molding method, for example, a cylindrical support member 107 can be formed by molding on one side of a nut of a cap stud. By arranging the support member 107 and the locking member 107 formed as a stud to be coaxially fixedly connected, the circumferential side surface of the cylindrical support member 107 can facilitate the user to perform a screwing operation, and its enlarged radius also enlarges the rotational torque acting on the locking member 107, so that the accessory assembly can be more convenient to install and remove. Further, in some embodiments, the circumferential side surface of the roughly cylindrical support member 107 can be provided with anti-slip lines to further facilitate the user to install and remove. In addition, a positioning recess 108-1 can also be formed on the axial end surface of the support member 107 facing the rear cover 102, and the positioning recess 108-1 is used to cooperate with the positioning protrusion 108 formed on the rear cover 102 to position the accessory assembly when the accessory assembly is installed.

[0095] In another scheme of this embodiment, the terminal body and the back cover are not fixed together by the accessory assembly, but are fixed together by other means. In this scheme, a positioning groove is provided on the outer surface of the back cover away from the terminal body, and the positioning groove is formed by the back cover surface being recessed in the direction of the terminal body. A locking member is provided on the accessory assembly, and the locking member is inserted into the positioning groove so that the accessory assembly is fixed on the mobile terminal and the accessory assembly is at least partially installed in the positioning groove. Specifically, the positioning groove 109 can be provided around the installation position of the accessory assembly on the back cover 102, for example, to position the accessory assembly after it is installed. The positioning groove 109 can be roughly circular, or can also be formed into other shapes, as long as there is enough space in the middle for installing and rotating the accessory assembly. A mounting groove 110 corresponding to the locking member 107 is provided in the center. For example, when the locking member 107 is a stud, the mounting groove 110 can be a corresponding threaded hole. In some embodiments, the terminal body 101 may also include a connection and fixing portion corresponding to the mounting groove 110, so that the locking member 107 of the accessory assembly can be further fixedly connected to the connection and fixing portion, thereby directly fixed to the terminal body 101. Through this arrangement, the positioning of the accessory assembly is achieved without adding additional screws or other fixing structures. For example, when the back cover 102 is thin or the weight of the accessory assembly is large, the connection and fixing portion can prevent the accessory assembly from falling off or even damaging the back cover 102 due to insufficient fixing force of the mounting groove 110. Alternatively, the mounting groove 110 may also include a portion extending into the terminal body 101 in a direction perpendicular to the surface of the back cover 102, which provides an additional fixing area for the locking member 107 of the accessory assembly, thereby improving the fixing force. It can be understood by those skilled in the art that in some other embodiments, the positioning groove 109 may not be provided, and the mounting groove 110 may be directly provided on the surface of the back cover 102, so that the accessory assembly can be directly fixedly connected to the back cover 102.

[0096] In some embodiments, the entire positioning groove 109 can be recessed from the surface of the back cover 102, so that the positioning groove 109 can at least partially accommodate the accessory component in a direction perpendicular to the plane of the back cover 102. By at least partially accommodating the accessory component, on the one hand, the probability of the peripheral part of the accessory component accidentally touching other obstacles and causing scratches can be reduced, and on the other hand, the thickness of the accessory component perpendicular to the back cover 102 can be ensured to ensure its structural strength. In addition, by partially accommodating the accessory component, the risk of accidentally releasing the connection with the back cover 102 due to rotation caused by friction on the circumferential side surface can also be reduced. In addition, the positioning groove 109 can be at least partially connected to the outside of the back cover 102 in a direction parallel to the back cover 102. For example, a break 109-1 can be provided at at least a portion of its circumferential side wall, so that the accessory component accommodated therein can be exposed from the break 109-1 in a direction parallel to the surface of the back cover 102. In the case where the camera module decoration 103 includes a connector formed as a stud, the exposed portion of the accessory component allows the user to access the side of the camera module decoration 103 and perform installation or removal operations on it.

[0097] It will be understood by those skilled in the art that, although some embodiments in which the locking member is set as a stud are described above, the present disclosure does not limit the specific connection method between the accessory component and the back cover. For example, the connecting portion of the accessory component may be a magnetic member such as a magnet, and by providing a corresponding magnetic adsorption member and a positioning groove at a corresponding position of the back cover, it can be adsorbed in the positioning groove by magnetic attraction. At the same time, in some embodiments, accessory components with a variety of different shapes or functions may be provided, and each accessory component may be configured with a corresponding magnetic member, and the terminal may identify different accessories by connecting with the different magnetic members. For example, in some embodiments, the connecting portion of the accessory component may be provided with a connector, and the connector may be matched with the corresponding positioning groove on the back cover by, for example, shape matching.

[0098] In some embodiments, the portion of the stud adjacent to the end surface of the support 107 may be provided with a metal bevel, and at the same time, the entrance of the screw hole on the back cover 102 also has a corresponding metal bevel, so that when the user tightens the stud, when the two metal 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 will not be scratched due to over-tightening, especially when the surface opposite to the back cover or the support 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 from being damaged due to excessive screwing force, and further avoids thread damage.

[0099] In some embodiments, the support member 107 can be made of transparent or translucent materials in whole or in part, and the support member 107 made of transparent or translucent materials can make it easy for the user to observe the situation inside the positioning groove 109. For example, when there is a foreign object in the positioning groove 109 or on the bottom side of the accessory component, if the foreign object cannot be detected in time and the accessory component is directly installed, it may cause scratches or even jamming and damage to the corresponding part of the accessory component or the back cover 102. In addition, setting the support member 107 of the accessory component to a transparent material can also visually reduce the thickness of the accessory component and improve the aesthetics. In some embodiments, a transparent member is provided at one end of the accessory component away from the body. Specifically, the camera module decorative member can be configured to include a transparent upper half and a non-transparent lower half, wherein the height of the non-transparent part of the bottom surface is flush with the surface of the back cover 102, which not only ensures the operability of the accessory component, but also ensures the consistency of appearance.

[0100] In some embodiments, the mobile terminal 100 is provided with N accessory components, where N is a positive integer greater than or equal to 1; the assembly position 106 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 through a locking member. The center of gravity of the mobile terminal 100 is located between the line connecting the first assembly position and the second assembly position and the center of the camera module decorative component.

[0101] The mobile terminal 100 may be installed with a plurality of accessory components with different functions, such as an aromatherapy box 500, a bracket 300, a lanyard 200, etc. Different accessory components may be installed on the mobile terminal 100 individually, or two or three accessory components may be installed on the mobile terminal 100 at the same time.

[0102] See also Figure 5The accessory assembly includes a first accessory assembly, which is a lanyard, and its two ends are fixedly arranged on the back cover 102 by means of bolts or the like, so that the user can hold the terminal and prevent the terminal from accidentally falling off. Specifically, the first accessory assembly has an extended length and two ends, and the two ends of the first accessory assembly are connected to two locking members 107, so that the first accessory assembly is fixedly installed on the mobile terminal 100. The number of mounting slots, assembly positions 106 and locking members 107 is consistent. In this solution, since the two ends of the first accessory assembly are fixed on the mobile terminal 100, two mounting slots need to be set on the terminal body, namely the first mounting slot and the second mounting slot. Two assembly positions 106 are also correspondingly set on the back cover 101, namely the first assembly position and the second assembly position. The two locking members 107 are respectively fixedly connected with 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 assembly are installed on the mobile terminal 100. The camera module decoration is usually set at the upper left corner of the mobile terminal 100, and the two ends of the first accessory component are respectively set at the left and right ends of the mobile terminal 100, so that the center of gravity of the mobile terminal 100 is located between the line connecting the first assembly position 106 and the second assembly position 106, and the center of the camera module decoration.

[0103] The mobile terminal 100 is also provided with a second accessory component different from the first accessory component, and the second accessory component is a support structure, which is also provided to at least partially protrude from the surface of the back cover 101. Since both the first accessory component and the second accessory component are provided to protrude from the surface of the back cover 101, when the mobile terminal 100 is placed on a placement plane such as a desktop, the back cover 101 of the mobile terminal 100 will be separated from the placement plane by the support and barrier of the first accessory component, the second accessory component and the camera module decoration, thereby avoiding being scratched or worn.

[0104] In one embodiment, only one accessory component is installed on the mobile terminal, and the accessory component is a lanyard. Next, the structure of the lanyard and how the lanyard is installed on the mobile terminal are described in detail.

[0105] See also Figures 6 to 8The accessory body is a lanyard body 201, and one end of the lanyard body 201 is connected to the rotating part 203. The cross section of the lanyard body 201 is circular, and an annular raised structure is provided at the end of the lanyard body 201. The rotating part 203 includes a fastening ring 2031 and a fixing ring 2032, wherein the fastening ring 2031 is a tubular structure with 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 fastening ring 2031. The lanyard body 201 and the fastening ring 2031 are injection molded together, and the raised structure at the end of the lanyard body 201 is clamped and limited with the limiting portion. In this solution, the fixing ring 2032 is also a tubular structure with a certain extension length and openings at both ends, the extension length of the fixing ring 2032 is greater than the extension length of the fastening ring 2031, and the diameter of the cross section of the fixing ring 2032 is also greater than the diameter of the cross section of the fastening ring 2031. After the end of the lanyard body 201 is fixedly connected to the fastening ring 2031 , the fastening ring 2031 is inserted into the fixing ring 2032 and the two are connected by injection molding.

[0106] In this solution, the connecting portion 202 is an integrally formed bent tube, and the bent tube includes a first straight tube section 2021, a bent section 2022, and a second straight tube section 2023 connected in sequence. In the assembled state, the first straight tube section 2021 is arranged perpendicular to the back cover 101 of the mobile terminal 100 and is fixedly connected to the stud, and the second straight tube section 2023 is arranged parallel to and suspended from the back cover 101 of the mobile terminal 100 and is connected to the fixing ring 2032 connected to the end of the lanyard body 201.

[0107] The fixing ring 2032 and the second straight pipe section 2023 are detachably connected by plugging and pulling. Specifically, the end of the second straight pipe section 2023 away from the bending section 2022 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 2032. The fixing ring 2032 has a first protruding structure 2033 protruding along the circumference of its inner side wall on one side away from the end of the lanyard body 201, and the first diameter section has a second protruding structure 2034 protruding along the circumference of its outer side wall, and there is a certain length of interval between the second protruding structure 2034 and the second diameter section. During installation, the first protruding structure 2033 is inserted into the interval between the second protruding structure 2034 and the second diameter section under external force, so that the rotating part 203 can be rotatably connected to the connecting part 202 along its axis.

[0108] Since the end of the lanyard body 201 needs to be connected to the rotating part by injection molding, the end of the lanyard body 201 is connected to the rotating part and the whole is used as a standard part. The lanyard body 201 can be connected to the mobile terminal 100 at only one end, or at both ends. When both ends of the lanyard body 201 are connected to the mobile terminal 100, then the two connecting parts 202 are first connected to the mobile terminal 100, and then the two ends of the lanyard body 201 are rotatably connected to the connecting part 202 through the rotating part 203. Or after one end of the lanyard body 201 is first connected to the connecting part 202, the connecting part 202 fixes one end of the lanyard body 201 on the mobile terminal 100 by a screw, and after the other connecting part 202 is also rotatably fixed on the mobile terminal 100, the other end of the lanyard body 201 is connected to the connecting part 202 through the rotating part 203.

[0109] In a specific scheme of this embodiment, a mobile phone is used as an example for explanation as a mobile terminal. The camera module decoration is arranged in the upper left corner area of ​​the mobile phone. A plurality of assembly positions 106 are arranged on the back cover, wherein the first assembly position is arranged in the area below the camera module decoration, the second assembly position is arranged symmetrically with the first assembly position on the right side of the mobile phone, and the third assembly position is arranged in the lower left corner area of ​​the mobile phone. When the lanyard as an accessory component is installed on the mobile phone, the two ends of the lanyard body are arranged obliquely on the mobile phone by being fixed at the second assembly position and the second assembly position. Since the mobile phone is usually equipped with a battery in the middle area when it is assembled, and the weight of the battery accounts for a large proportion of the weight of the entire mobile phone, the center of gravity of the mobile terminal is usually located in the middle area. That is to say, in this scheme, the two ends of the lanyard are arranged obliquely on the back cover of the mobile phone, so that the center of gravity of the mobile phone is located between the lanyard body and the camera module decoration, so that when the user places the back cover of the mobile phone on a desktop or other plane, the rotating parts at the two ends of the lanyard and the camera module decoration form a three-point support, and the back cover is suspended on the desktop to prevent the back cover from being scratched.

[0110] Of course, in other embodiments, the two ends of the lanyard may also be installed on the symmetrically arranged first assembly position and the second assembly position.

[0111] In the above solution, since both ends of the lanyard body 201 are fixed on the mobile terminal 100, even if the stud and the mounting groove are not fully assembled in place, the back cover 101 can still be fixed on the terminal body.

[0112] In a preferred embodiment, the lanyard body 201 is made of a flexible material with elastic deformation, and when both ends thereof are fixed to the two sides of the mobile terminal 100, the lanyard body 201 is attached to the back cover 101 of the mobile terminal 100. When the user uses it, the fingers are inserted between the lanyard body 201 and the back cover 101, thereby fixing the mobile terminal 100 on the user's hand.

[0113] In other embodiments, the lanyard body 201 may also be a sheet-like elastic structure.

[0114] In a preferred solution of this embodiment, the height of the side of the fixing ring 2032 away from the surface of the back cover 101 protruding from the surface of the back cover 101 is the same as the height of the camera module decoration protruding from the surface of the back cover 101. When both ends of the lanyard body 201 are connected to the mobile terminal 100, the two fixing rings 2032 at both ends of the lanyard body 201 and the camera module decoration form a triangle, and when the mobile terminal 100 is placed on a plane, the back cover 101 does not abut against the plane, thereby preventing the back cover 101 from being scratched or damaged.

[0115] See also Fig. 9 In a specific embodiment, the accessory component can also be a card holder. The card holder includes a bottom plate 401 abutting against the back cover 101 of the mobile terminal 100, and a card holder body 402 covered above the bottom plate 401 and magnetically connected thereto, and a receiving cavity is provided between the bottom plate 401 and the card holder body 402 for receiving cards, change, etc. The card holder can be, for example, roughly in the shape of a flat box, and the bottom plate 401 is fixedly connected to the first accessory component at one corner, and can be fixedly connected to the back cover 101 of the mobile terminal 100 at the other three corners by means of screws or other mechanisms. In some embodiments, the height of the card holder perpendicular to the plane of the back cover 101 of the mobile terminal 100 can be flush with the height of the first accessory component, so that the plane of the card holder can support the mobile terminal 100 together with the first camera module decorative part, thereby further improving the stability of the mobile terminal 100 when placed.

[0116] Specifically, the bottom plate has a plurality of locking positions which are arranged through, and the locking positions are arranged corresponding to the assembly positions on the back cover. During installation, the locking member passes through the locking positions and the assembly positions of the back cover in sequence to fix the bottom plate on the back cover. A first magnetic member is arranged on a side of the bottom plate away from the back cover, and a second magnetic member is arranged on the card holder body. The first magnetic member and the second magnetic member are relatively adsorbed to connect the card holder body to the bottom plate.

[0117] More specifically, during the installation process, in order to enable the first magnetic member and the second magnetic member to correspond more quickly and accurately, a positioning portion is provided on the bottom plate at the position where the first magnetic member is located, wherein the positioning portion can be a positioning groove or other forms. The positioning portion can guide the second magnetic member on the card package body to quickly correspond to and abut against the first magnetic member.

[0118] See also Figures 10 to 15In a specific embodiment, the accessory component can also be a bracket. In some embodiments, a movable support member can also be connected to the accessory component, and the movable support member is used to further support the terminal. For example, the movable support member can be a support plate component hingedly connected to the protruding portion of the accessory component. The support plate component can be, for example, roughly in the shape of a long strip, and one end along its length direction is hinged to the surface of the accessory component by means of a second rotation axis 305, so that the support plate component as a whole can pivot around the hinge axis of the second rotation axis 305. In some embodiments, the hinge axis of the second rotation axis 305 can be set parallel to the length direction of the terminal. In this case, when the support plate component as a whole is pivoted around the hinge axis to turn away from the terminal, the side surface of the bottom end of the support plate component 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 plate component 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 plate assembly is arranged to be parallel to the bottom side of the terminal, the present disclosure does not limit the specific arrangement of the support plate assembly. For example, the second rotation axis 305 can be arranged to have a certain inclination angle with respect to the length direction of the terminal, so that the support plate assembly 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 second rotation axis 305 relative to the terminal can be arranged to be adjustable as needed.

[0119] In some embodiments, the bracket 300 includes a turntable assembly 301, which includes an upper turntable 3011 and a lower turntable 3012, wherein the upper turntable 3011 and the lower turntable 3012 are respectively provided with through holes for relative rotation of the two along a first rotation axis; a stud, which is used to pass through the through holes of the upper turntable 3011 and the lower turntable 3012, and is fixedly connected to the lower turntable 3012, and is relatively rotatably connected to the upper turntable 3011, and the stud is detachably connected to the assembly position 106 on the back cover 101 of the mobile terminal 100; and a camera module decorative part, which is used to be connected to the upper surface of the upper turntable 3011 through a rotating shaft, and changes the angle between the upper turntable 3011 and the upper turntable 3011 by rotating along a second rotation axis 305. When the bracket 300 is installed on the back cover 101 of the mobile terminal 100, it can provide support for the mobile terminal 100 at multiple angles.

[0120] In this solution, the bracket 300 includes a turntable assembly 301, a stud and a camera module decoration. The turntable assembly 301 is connected to the camera module decoration, and the stud installs the turntable assembly 301 on the mobile terminal 100. Specifically, the turntable assembly 301 is a circular structure, which includes an upper turntable 3011 and a lower turntable 3012 arranged opposite to each other. The middle areas of the upper turntable 3011 and the lower turntable 3012 are 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 3011 and the lower turntable 3012 in turn, the back cover 101 is fixed to the mobile terminal 100 by cooperating with the assembly position 106 on the back cover 101. At the same time, the stud also fixes the turntable assembly 301 to the back cover 101 of the mobile terminal 100. The stud is fixedly connected to the lower turntable 3012 by a metal spring 307, and is relatively rotatably connected to the upper turntable 3011. The camera module decoration is connected to the upper surface of the upper turntable 3011 through a rotating shaft, and changes the angle between the camera module decoration and the upper turntable 3011 by rotating along a second rotating shaft. When the bracket 300 is installed on the back cover 101 of the mobile terminal 100, it can provide support for the mobile terminal 100 at multiple angles.

[0121] The solution of this embodiment also includes: an annular groove structure 3013 is provided at the connection between the lower turntable 3012 and the upper turntable 3011; a protruding sliding portion 3014 is provided on the turntable assembly 301 at one end that cooperates with the groove; the sliding portion 3014 is inserted into the groove structure 3013 and can slide along the groove and rotate around the first rotation axis.

[0122] In a specific solution of this embodiment, the upper turntable 3011 and the lower turntable 3012 can rotate relative to each other. Specifically, an annular groove structure 3013 is provided at the connection between the lower turntable 3012 and the upper turntable 3011, and a stopper 3015 is provided in the groove structure 3013. The upper turntable 3011 is an open groove-shaped structure, and the inner surface of the upper turntable 3011 has a protruding sliding portion 3014. When the upper turntable 3011 and the lower turntable 3012 are matched, the side wall cover of the upper turntable 3011 is provided on the outer periphery of the side wall of the lower turntable 3012, and the sliding portion 3014 on the surface of the upper turntable 3011 is inserted into the groove structure 3013 and can slide along the groove structure 3013 and rotate around the first rotation axis. In this solution, in order to reduce the friction between the upper turntable 3011 and the lower turntable 3012 , a POM gasket 306 is provided between the upper turntable 3011 and the lower turntable 3012 .

[0123] The camera module decoration part includes an upper support plate 3021, a lower support plate 3022, and a metal part 303 disposed therebetween. The metal part 303 is a plate-shaped structure, one end of which is fixedly connected to the lower support plate 3022. The other end is wrapped around the second shaft at the second shaft with interference fit to form the second shaft rotating part 203. The upper support plate 3021 has a certain thickness and a recessed area on its lower surface. The lower support plate 3022 with the metal part 303 fixed thereto is fixed in the recessed area of ​​the upper support plate 3021 by injection molding, and the surface of the upper support plate 3021 after injection molding is a planar structure.

[0124] The upper turntable 3011 has a mounting portion 304 protruding from its upper surface. The mounting portion 304 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 203 on the metal member 303 has a mounting hole, which 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.

[0125] See also Fig.16 In a specific embodiment, the accessory component can also be a pendant. The accessory component includes a support member 601, a fixing groove 601-1 that is circumferentially inwardly recessed, and a movable support member includes a fixing ring 602 that is roughly elliptical in shape. The fixing ring 602 surrounds the outer circumference of the fixing groove 601-1, and the inner side of the fixing ring 602 is embedded in the fixing groove 601-1, so that the fixing ring 602 is connected to the accessory component in a rotatable manner. The fixing ring 602 is connected to a quick-release buckle 603 in a detachable buckle connection manner. With the help of the combination of the fixing ring 602 and the quick-release buckle 603, the movable support member can be further connected to other components, such as a fixed lock, a wristband, etc., so that the terminal can be connected or supported on other supports in an unrestricted manner.

[0126] See also Fig.17 In a specific embodiment, the accessory component may also be an aromatherapy box. The aromatherapy box has a hollow structure, and a receiving cavity is defined inside. The receiving cavity may be used to receive fragrance agents such as solid spices, so that the aromatherapy box provides a fragrance effect to the user when used. In some embodiments, the receiving cavity may be connected to the outside through an axial opening 501 provided on the axial end surface of the camera module decorative component and / or a side opening 502 provided on the circumferential side surface of the camera module decorative component, so as to release the fragrance substance outward.

[0127] It will be understood by those skilled in the art that, although the above describes an embodiment in which the assembly portion 103 is used to fix the accessory component, in some embodiments, the assembly portion can be used to fix other types of accessory components. For example, one or more mounting holes on an accessory component can be made to correspond to one or more of the multiple assembly portions 103, so that the accessory component can be connected to the back of the mobile terminal with the help of a connector such as a stud. At the same time, according to actual usage, the accessory component can be flexibly set at the corresponding position of some of the multiple assembly portions, further enriching its types of uses.

[0128] Those skilled in the art can understand that the various accessory components described in the above-mentioned embodiments can be used in the form of independent rear cover accessories in conjunction with the same or similar terminals. That is, each rear cover accessory includes the same or similar locking member and can be installed in correspondence with the corresponding assembly position on the corresponding rear cover. In this way, it is possible to interchange various accessory components on the same terminal according to different needs, allowing users to select the accessory components they need to use according to the actual usage scenario, greatly improving the scalability of terminal functions.

[0129] The solution of this embodiment also includes: an electronic component module is also provided on the accessory assembly, and the electronic component module is electrically connected to the identification control module of the mobile terminal through a locking member.

[0130] In the above, since the stud is a metal part, an electronic component module can be set in the accessory component, and the sensor is electrically connected to the identification control module of the mobile terminal through the connection structure such as the stud. For example, in some embodiments, a pressure sensor is set on the outer surface of the accessory component to provide a press signal pickup, and then send a control instruction to the terminal.

[0131] In some embodiments, when the mobile terminal is placed on a plane, the part of the accessory component that contacts the plane is the camera module decoration. In this solution, a physical button can be set on the camera module decoration of the accessory component, for example, and the protruding part of the accessory component can be made into a button with a certain damping effect.

[0132] The solution of this embodiment further provides a control method for a mobile terminal, the control method comprising: detecting different control instructions issued by the electronic component module; and in response to detecting different control instructions, identifying a control module to start different functions corresponding to the control instructions.

[0133] In some embodiments, in addition, a button can be set on the protruding side of the camera module decoration of the accessory component, 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 camera module decoration. By making corresponding settings for the recognition control module of the mobile terminal, after the mobile terminal detects the button including the corresponding accessory, it can start different button functions in response to the pressing of the corresponding button. For example, when playing a game, pressing the button on the accessory component 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 the next song, pressing three times to control 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 behind the mobile terminal, the button can be used as a touch switch for starting or closing the light strip.

[0134] 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.

[0135] A display screen can also be set up to provide more interactive effects.

[0136] The solution of this embodiment also includes: different accessory components are provided with different detected parts, and the mobile terminal is provided with a sensor capable of identifying different detected parts. The sensor is a Hall element, and the detected parts are magnetic parts with different magnetic fluxes. The Hall element identifies different accessory components according to information of the magnetic parts.

[0137] In the scheme disclosed herein, a sensor is installed on the mobile terminal, a detected part is provided on the accessory component, and the detecting parts on different accessory components are different, so that the sensor on the mobile terminal can determine the category of the accessory component corresponding to the detecting part according to the difference of the detecting part.

[0138] In a specific implementation scheme, the sensor on the mobile terminal is a Hall element, and different accessory components are provided with magnetic parts with different magnetic fluxes. The Hall element identifies different accessory components based on the information of the magnetic parts. For example, a card holder, a lanyard, a bracket, and an aromatherapy box are all provided with magnetic parts with different magnetic fluxes, and the Hall element can determine the type of accessory component installed on the mobile terminal based on the magnetic flux information on the magnetic parts.

[0139] In a further solution of this embodiment, the sensor can not only determine the category information of the accessory component, but also determine the status information of the accessory component. For example, when the sensor determines that the accessory component is a bracket based on the magnetic flux, the sensor can further detect whether the bracket is in a supporting state or a storage state when it is in working state. When the accessory component is an aromatherapy box, the sensor can record the time from the beginning of the connection when determining that the accessory component is an aromatherapy box. For example, after 10 days, it will be prompted that the fragrance in the aromatherapy box has run out and needs to be replenished or the fragrance tablets need to be replaced. Of course, different types of sensors need to be set for different detection functions.

[0140] In addition, in some embodiments, the present disclosure further provides a protective case for a mobile 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 camera module decorative piece and an accessory component protruding perpendicularly to the back plane of the protective case, and a positioning groove for mounting the accessory component is provided on the mobile phone protective case, and the accessory component is detachably arranged in the positioning groove.

[0141] The present disclosure provides a camera module decorative part and a detachable accessory component, so that the mobile terminal can avoid direct contact between the back cover and the placement plane, and can avoid the situation where the terminal cannot be placed flat due to the raised part of the camera component, so that it contacts the placement plane in an inclined posture, resulting in additional wear of the contact part. Furthermore, by providing the accessory component as a separately replaceable back cover accessory, it can be replaced more flexibly and conveniently when wear occurs, and provides customers with more flexible choices.

[0142] The solution provided in this embodiment fixes the lanyard to the mobile terminal by installing the locking parts of the mobile terminal body and the back cover without additional fixing parts, which not only reduces the cost but also enables the user to perform operations more conveniently by holding the mobile terminal, thereby improving the user experience.

[0143] Although multiple embodiments of the present disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art may think of many changes, modifications, and alternatives without departing from the thought and spirit of the present disclosure. It should be understood that in the process of practicing the present disclosure, various alternatives to the embodiments of the present disclosure described herein may be adopted.
