[0039] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0040] With the increasing functions of electronic devices such as smart phones and the continuous innovation of application technologies of smart phones and other electronic devices, the competition among various manufacturers for smart phones and other electronic devices has become increasingly fierce, and all are striving to pursue better design solutions and cost control.

[0041] In the related art, as Figures 1-3 shown, the electronic device includes a middle frame. Generally, the frame of the middle frame is formed by processing profile aluminum. Specifically, the profile aluminum of the frame is formed by a large aluminum plate 1 (as Figure 1 shown), and the middle part is removed by computer numerically controlled precision machining, i.e., CNC machining, to form a frame 2 (as Figure 2 shown), and then the frame 2 is welded and fixed to a die-cast middle plate 3 to form a middle frame (as Figure 3 shown). In this processing method, it is necessary to perform an overall blanking process on the hollow area inside the middle frame, and the amount of aluminum raw material used is about 310 grams, resulting in serious waste of raw materials and high processing costs.

[0042] To solve the above technical problems, according to the first aspect of the embodiments of the present disclosure, a middle frame assembly is provided.

[0043] As Figures 5-6 , Figure 8 and Figure 9 shown, the middle frame assembly includes: a middle plate 3 and a frame member 20.

[0044] The frame member 20 includes at least two frames. At least two frames are connected end to end in sequence to enclose a ring-shaped frame member 20 and are disposed on the outer peripheral side of the middle plate 3; wherein, at least two frames include: two adjacent first frames 21 and second frames 22. The first frame 21 has a first mating surface 211, and the second frame 22 has a second mating surface 221. At least a latching structure 40 capable of being mutually latched is provided on the first mating surface 211 and the second mating surface 221, and the first frame 21 and the second frame 22 are connected through the latching structure 40.

[0045] Wherein, the frame member 20 and the middle plate 3 are connected by die casting, which improves the reliability of the connection between the frame member 20 and the middle plate 3.

[0046] In the present disclosure, the first housing 21 may be a U-shaped housing, and the second housing 22 may be a U-shaped housing. The first housing 21 has a first mating surface 211, and the second housing 22 has a second mating surface 221. At least a latching structure 40 capable of being latched with each other is provided on the first mating surface 211 and the second mating surface 221. The first housing 21 and the second housing 22 are connected by the latching structure 40. At least two housings are connected end to end in sequence to enclose an annular frame member 20, eliminating the need for overall blanking of the hollow area inside the middle frame, reducing the processing difficulty while saving raw materials. At the same time, there is no need to integrally extrude to obtain the frame member 20, avoiding problems such as large investment in processing equipment and high requirements for processing accuracy, thereby saving product costs.

[0047] In some possible implementation manners, as Figure 6 and Figure 8 shown, the latching structure 40 includes: a recessed portion 401 and a connecting portion 402, and the connecting portion 402 is latched in the recessed portion 401.

[0048] Exemplarily, the recessed portion 401 may be provided on the first mating surface 211. Correspondingly, the connecting portion 402 is provided on the second mating surface 221, and the connecting portion 402 is latched in the recessed portion 401, so that the first housing 21 and the second housing 22 are connected by the latching structure 40. At least two housings are connected end to end in sequence to enclose an annular frame member 20, eliminating the need for overall blanking of the hollow area inside the middle frame, reducing the processing difficulty while saving raw materials.

[0049] Exemplarily, the recessed portion 401 may be provided on the second mating surface 221. Correspondingly, the connecting portion 402 is provided on the first mating surface 211, and the connecting portion 402 is latched in the recessed portion 401, so that the first housing 21 and the second housing 22 are connected by the latching structure 40. At least two housings are connected end to end in sequence to enclose an annular frame member 20, eliminating the need for overall blanking of the hollow area inside the middle frame, reducing the processing difficulty while saving raw materials.

[0050] In some possible implementation manners, as Figure 6 and Figure 8 shown, the recessed portion 401 is recessed in a first direction, and the first direction is different from the extending direction of the frame member 20.

[0051] Among them, the frame member 20 may be a circular member, a rectangular member, or a frame member of other shapes, and the embodiments of the present disclosure do not make specific limitations thereon.

[0052] Exemplarily, taking the frame member 20 as a rectangular member for illustration, the first direction may be the length direction Y of the frame member 20 or the width direction X of the frame member 20, as long as it is ensured that the recessed direction of the recessed portion 401 is different from the extending direction of the frame member 20 to play a role of latching and limiting.

[0053] In some possible embodiments, such as Figure 8 shown, the engaging structure 40 includes a first engaging member 41 and a second engaging member 42. The first engaging member 41 includes a first portion 411 extending in a first direction and a second portion 412 extending from a first side of the first portion 411 in the first direction; and, the second engaging member 42 includes a third portion 421 extending in the first direction and a fourth portion 422 extending from a first side of the third portion 421 in the first direction. The first portion 411 and the third portion 421 are snap-connected, and the second portion 412 and the fourth portion 422 are snap-connected.

[0054] Taking the frame member 20 as a rectangular member for illustration, the first direction can be the length direction of the frame member 20 or the width direction of the frame member 20.

[0055] Among them, the first engaging member 41 can be disposed on the first frame body 21, the second engaging member 42 can be on the second frame body 22, and the first engaging member 41 and the second engaging member 42 are snap-connected and limited to each other; and / or,

[0056] The first engaging member 41 is disposed on the second frame body 22, the second engaging member 42 is disposed on the first frame body 21, and the first engaging member 41 and the second engaging member 42 are snap-connected and limited to each other.

[0057] The engaging structure 40 can be a snap structure. The first portion 411 can be a groove structure. Correspondingly, the third portion 421 is a protrusion structure. The second portion 412 can be a protrusion structure. Correspondingly, the fourth portion 422 is a groove structure. Or, the first portion 411 can be a groove structure. Correspondingly, the third portion 421 is a protrusion structure. The second portion 412 can be a groove structure. Correspondingly, the fourth portion 422 is a protrusion structure. Or, the first portion 411 can be a protrusion structure. Correspondingly, the third portion 421 is a groove structure. The second portion 412 can be a protrusion structure. Correspondingly, the fourth portion 422 is a groove structure. Such as Figure 6 shown, so that the first frame body 21 and the second frame body 22 can be detachably assembled to define the frame member 20, and limit the X direction and the Y direction.

[0058] In some possible embodiments, such as Figure 5 shown, an assembling structure 30 is disposed between the first mating surface 211 and the second mating surface 221. The assembling structure 30 is located on one side of the engaging structure 40, and the first frame body 21 and the second frame body 22 are connected through the assembling structure 30.

[0059] In the embodiments of the present disclosure, by providing the assembling structure 30, the assembling strength of the first frame body 21 and the second frame body 22 is further enhanced.

[0060] In some possible embodiments, such as Figure 5As shown, the assembly structure 30 includes a first surface 31 and a second surface 32 opposite to the first surface 31. At least part of the first surface 31 and the second surface 32 are welded, bonded, and / or riveted. The first surface 31 is part of the first mating surface 211, and the second surface 32 is part of the second mating surface 221.

[0061] In the embodiment of the present disclosure, by providing the assembly structure 30 with opposite first surface 31 and second surface 32, at least part of the first surface 31 and the second surface 32 are connected by welding, bonding, and / or riveting, further enhancing the assembly strength of the first frame 21 and the second frame 22.

[0062] In some possible implementation manners, as Figure 6 shown, compared with the assembly structure 30, the engaging structure 40 is disposed at a position of the frame member 20 close to the middle plate 3.

[0063] In the embodiment of the present disclosure, during the assembly process of the frame member 20, the first frame 21 and the second frame 22 are first engaged and fixed by the engaging structure 40 at a position close to the middle plate 3, and then strengthened by the assembly structure 30 at a position far from the middle plate 3, which is convenient for the processing and manufacturing of the frame member 20.

[0064] In some possible implementation manners, as Figure 6 and Figure 8 shown, the frame member 20 includes: a first frame 21 and a second frame 22.

[0065] The second frame 22 is disposed opposite to the first frame 21. Two ends of the first frame 21 and two ends of the second frame 22 are connected by the engaging structure 40 to enclose a ring-shaped frame member 20.

[0066] In the embodiment of the present disclosure, the first frame 21 may be a U-shaped frame, and the second frame 22 may be a U-shaped frame. The first frame 21 and the second frame 22 are connected by the engaging structure 40 to enclose a ring-shaped frame member 20, without the need for overall blanking treatment of the hollow area inside the middle frame, reducing the processing difficulty while saving raw materials. At the same time, there is no need to integrally extrude to obtain the frame member 20, avoiding problems such as large investment in processing equipment and high requirements for processing accuracy, thereby saving product costs.

[0067] In some possible implementation manners, as Figure 5 shown, the frame member 20 extends a first connecting portion 23 in the second direction. The first connecting portion 23 is fixedly connected to the outer peripheral side of the middle plate 3, and the second direction is different from the first direction.

[0068] Taking the frame member 20 as a rectangular member for illustration, the first direction may be the length direction Y of the frame member 20 or the width direction X of the frame member 20, and the second direction can be understood as the thickness direction Z of the frame member 20.

[0069] In the disclosed embodiment, the first connection portion 23 of the frame member 20 is fixedly connected to the outer peripheral side of the middle plate 3 by welding, bonding, or the like.

[0070] In some possible implementations, the middle plate 3 includes an antenna (not shown in the figure), and the engaging structure 40 between the first mating surface 211 and the second mating surface 221 is arranged corresponding to the antenna.

[0071] In the embodiment of the present disclosure, the snap-fitting structure 40 of the first mating surface 211 and the second mating surface 221 is arranged corresponding to the antenna. During the subsequent fine processing, it is necessary to groove the first mating surface 211 and the second mating surface 221 and fill them with insulating parts. The grooves serve as the breaks of the antenna, and the breaks filled with insulating parts serve as the clearance area of ​​the antenna. The clearance area of ​​the antenna can radiate signals through the antenna to meet the antenna performance requirements.

[0072] Based on the same inventive concept, according to a second aspect of the present disclosure, an electronic device is provided, and the electronic device includes a middle frame assembly as in any one of the embodiments of the first aspect.

[0073] The electronic device may be a smart phone, a tablet computer, a laptop computer or a wearable smart device.

[0074] In the present disclosure, the first frame 21 can be a U-shaped frame, and the second frame 22 can be a U-shaped frame. The first frame 21 has a first mating surface 211, and the second frame 22 has a second mating surface 221. The first mating surface 211 and the second mating surface 221 are at least provided with a snap-fit ​​structure 40 that can be snapped into each other. The first frame 21 and the second frame 22 are connected by the snap-fit ​​structure 40. At least two frames are connected end to end in sequence to form a ring-shaped frame member 20. There is no need to perform overall blanking processing on the hollow area inside the middle frame, which reduces the processing difficulty and saves raw materials. At the same time, there is no need to extrude the frame member 20 as a whole, which avoids the problems of large investment in processing equipment and high processing precision requirements, thereby saving product costs.

[0075] According to the third aspect of the embodiment of the present disclosure, Figure 4 As shown, a method for processing a frame member is provided, comprising the following steps:

[0076] In step S100, the profile is processed into a frame of a preset shape.

[0077] The preset shape may be a rectangle, an ellipse, or other shapes, and the present disclosure does not make any specific limitation on this.

[0078] like Figure 8 As shown, the frame can be a closed integral structure or a plurality of spliced ​​structures, and the present disclosure does not make any specific limitation on this.

[0079] In the embodiments of the present disclosure, by processing the profile into a frame body with a preset shape, there is no need to perform an overall blanking process on the hollow area inside the middle frame, which reduces the processing difficulty and saves raw materials at the same time.

[0080] In step S200, at least two frame bodies are connected end to end in sequence to enclose a ring-shaped initial blank of the border member; at least two frame bodies include: two adjacent first frame bodies and second frame bodies, the first frame body has a first mating surface, the second frame body has a second mating surface, and at least a latching structure capable of mutually latching is provided on the first mating surface and the second mating surface, and the first frame body and the second frame body are connected through the latching structure.

[0081] In step S300, the initial blank of the border member is truncated at a preset interval to obtain a plurality of border members.

[0082] Among them, the preset interval is determined according to the design requirements of the middle frame, and the present disclosure does not make specific limitations thereto.

[0083] It can be understood that as Figure 6 shown, the initial blank of the border member is processed by computer numerically controlled precision machining, that is, the border member of the middle frame is processed by CNC. In order to facilitate the formation of the antenna clearance area, the antenna clearance area can transmit antenna radiation signals to meet the antenna performance requirements.

[0084] In the embodiments of the present disclosure, by truncating the initial blank of the border member at a preset interval to obtain a plurality of border members, there is no need to perform an overall blanking process on the hollow area inside the middle frame, which reduces the processing difficulty and saves raw materials at the same time.

[0085] In the present disclosure, an aluminum rod is used as the raw material, and the aluminum rod is processed into a frame body with a preset shape in a preset shape. At least two frame bodies are connected end to end in sequence to enclose a ring-shaped initial blank of the border member; the initial blank of the border member is truncated at a preset interval to obtain a plurality of border members. There is no need to perform an overall blanking process on the hollow area inside the middle frame, which reduces the processing difficulty and saves raw materials at the same time.

[0086] In some embodiments, as Figure 7 shown, step S200, the step of connecting at least two frame bodies end to end in sequence to enclose a ring-shaped initial blank of the border member, includes the steps of:

[0087] Step S201, forming a first frame body with a first mating surface and forming a second frame body with a second mating surface.

[0088] Among them, as Figure 8 shown, the first frame body 21 may be a U-shaped frame body, correspondingly, the cross-sectional shape of the first mating surface is U-shaped; the second frame body 22 may be a U-shaped frame body, correspondingly, the cross-sectional shape of the second mating surface is U-shaped.

[0089] In the embodiments of the present disclosure, by separately forming the first frame body 21 having the first mating surface and the second frame body 22 having the second mating surface, there is no need to perform an overall blanking process on the hollow area inside the middle frame, reducing the processing difficulty and saving raw materials at the same time.

[0090] Step S202, obtaining a preliminary blank of the frame member by engaging the first mating surface with the second mating surface.

[0091] Among them, the first frame body 21 and the second frame body 22 can be positioned and assembled through detachable connection, and the first frame body 21 and the second frame body 22 can also be limited and fixed through fixed connection to obtain a preliminary blank of the frame member.

[0092] In the embodiments of the present disclosure, a preliminary blank of the frame member is obtained by engaging the first mating surface with the second mating surface. Through the processing method of splicing to form the preliminary blank of the frame member, there is no need to perform an overall blanking process on the hollow area inside the middle frame, reducing the processing difficulty and saving raw materials at the same time.

[0093] In some embodiments, step S201, the steps of forming the first frame body having the first mating surface and forming the second frame body having the second mating surface include the steps:

[0094] Forming the first frame body having the first mating surface and forming the second frame body having the second mating surface by extrusion, and / or forming the first frame body having the first mating surface and forming the second frame body having the second mating surface by die casting.

[0095] Among them: the frame body is prepared by extrusion or die casting.

[0096] One processing method is: using an aluminum rod as the raw material, extruding the aluminum rod into the first frame body having the first mating surface and forming the second frame body having the second mating surface in a preset shape, connecting at least two frame bodies end to end in sequence to enclose a ring-shaped preliminary blank of the frame member; truncating the preliminary blank of the frame member at a preset interval to obtain a plurality of frame members. There is no need to perform an overall blanking process on the hollow area inside the middle frame, reducing the processing difficulty and saving raw materials at the same time.

[0097] Another processing method is: using an aluminum rod as the raw material, die casting the aluminum rod into the first frame body having the first mating surface and forming the second frame body having the second mating surface in a preset cross-sectional shape, connecting at least two frame bodies end to end in sequence to enclose a ring-shaped preliminary blank of the frame member; truncating the preliminary blank of the frame member at a preset interval to obtain a plurality of frame members. There is no need to perform an overall blanking process on the hollow area inside the middle frame, reducing the processing difficulty and saving raw materials at the same time.

[0098] In some embodiments, as Figure 10 shown, before the step of truncating the preliminary blank of the frame member at a preset interval in step S300 to obtain a plurality of frame members, it further includes:

[0099] Step S400: Form a latching structure on the first mating surface and the second mating surface that can latch with each other.

[0100] Exemplarily, as Figures 5-6 , Figure 8 shown, the frame member 20 includes at least two frame bodies. At least two frame bodies are connected end to end in sequence to enclose a ring-shaped frame member 20 and are disposed on the outer peripheral side of the middle plate 3. Among them, at least two frame bodies include two adjacent first frame bodies 21 and second frame bodies 22. The first frame body 21 has a first mating surface 211, and the second frame body 22 has a second mating surface 221. At least a latching structure 40 that can latch with each other is provided on the first mating surface 211 and the second mating surface 221. The first frame body 21 and the second frame body 22 are connected through the latching structure 40.

[0101] In some embodiments, in step S400, the step of forming a latching structure on the first mating surface and the second mating surface that can latch with each other includes the steps of:

[0115] In some possible implementation manners, as Figure 8 shown, the engaging structure 40 includes a first engaging member 41 and a second engaging member 42. The first engaging member 41 includes a first part 411 extending in a first direction and a second part 412 extending from a first side of the first part 411 in the first direction; and the second engaging member 42 includes a third part 421 extending in the first direction and a fourth part 422 extending from a first side of the third part 421 in the first direction. The first part 411 and the third part 421 are snap-connected, and the second part 412 and the fourth part 422 are snap-connected.

[0116] Taking the frame member 20 as a rectangular member for illustration, the first direction can be the length direction of the frame member 20 or the width direction of the frame member 20.

[0117] Wherein, the first engaging member 41 can be arranged on the first frame 21, the second engaging member 42 can be on the second frame 22, and the first engaging member 41 and the second engaging member 42 are snap-connected and limited to each other; and / or,

As Figure 6 shown, so that the first housing 21 and the second housing 22 can be detachably assembled to define the frame member 20, and limit in the X direction and the Y direction.

[0120] In some possible implementation manners, the middle plate 3 includes an antenna (not shown in the figure), and the engaging structure 40 between the first mating surface 211 and the second mating surface 221 is arranged corresponding to the antenna.

[0121] In the embodiment of the present disclosure, the engaging structure 40 of the first mating surface 211 and the second mating surface 221 is arranged corresponding to the antenna. During subsequent finishing, it is necessary to slot the first mating surface 211 and the second mating surface 221 and fill with an insulating member. The slot is used as a slit of the antenna, and the slit filled with the insulating member is used as a clearance area of the antenna. The antenna clearance area can transmit antenna radiation signals to meet the antenna performance requirements.

[0122] In some embodiments, when machining the middle frame: the middle plate is prepared with a preset size. Among them, the middle plate is prepared with a plate member as the raw material.

[0123] The plate member may have a first surface to be machined and a second surface to be machined which are oppositely arranged. The first surface to be machined is substantially parallel to the second surface to be machined. Further, both the first surface to be machined and the second surface to be machined are flat surfaces. The plate member may be obtained by a blanking process. The first surface to be machined and the second surface to be machined are obtained by a grinding process.

[0124] The plate member may also be formed by an extrusion process. Both the first surface to be machined and the second surface to be machined are surfaces of the largest area of the plate member, so as to facilitate machining more structural features on the first surface to be machined and the second surface to be machined, and also increase the number of middle plate structures that the plate member can provide.

[0125] The middle plate and the frame member are connected to obtain the middle frame.

[0126] The middle frame is obtained by nano-injection molding and undergoes a series of appearance processes, such as CNC machining and oxidation treatment, to obtain the middle frame bare shell.

[0127] In the embodiments of the present disclosure, as Figure 9 shown, the middle plate 3 and the border member 20 are connected by die-casting, which improves the reliability of the connection between the middle plate 3 and the border member 20 and at the same time improves the forming speed of the middle frame.
