The auxiliary frame wall is arranged on the outer side of the first frame edge away from the setting space, corresponding to the position of the opening, and is located within the opening. A first engaging portion is arranged on the inner side of the first frame edge facing the setting space. The first engaging portion includes a plurality of blocks for engaging with the second frame. The first frame is fixed in the accommodation space by a hot pressing process. The first frame plate is attached to the back plate, and the first frame edge is attached to the frame edge. The electronic devices include a main board assembly and an antenna assembly arranged on the main board assembly. The antenna assembly is arranged on one side of the main board assembly adjacent to the opening.

[0052] Among them, the second frame includes a support portion made of non-metallic material. A connecting portion is arranged on one side of the support portion facing the first frame, and an extension portion is arranged on one side of the support portion facing the display module. The connecting portion is arranged on one side of the support portion facing the first frame and is in a strip shape extending along the edge of the support portion. A second engaging portion is arranged on the connecting portion. The second engaging portion includes a plurality of slots for engaging with a plurality of blocks on the first frame. The plurality of slots correspond to the positions of the plurality of blocks. The extension portion includes a vertical portion perpendicular to the plane of the second frame and a horizontal portion parallel to the plane of the second frame. The first end of the vertical portion is connected to the support portion, the second end of the vertical portion extends outward from the support portion in a direction perpendicular to the plane of the second frame, the first end of the horizontal portion is connected to the second end of the vertical portion, and the second end of the horizontal portion extends outward from the support portion in a direction parallel to the plane of the second frame. The horizontal portion of the extension portion has a first side surface and a second side surface. The horizontal portion is pressed on the upper end portion of the rear shell.

The vertical portion and the support portion form a bearing space for bearing the display module. The outer surface of the second end of the vertical portion is flush with the outer surface of the display module.

[0053] Wherein, the display module is fixed in the bearing space through an adhesive layer, the cover plate is arranged on the surface of the display module away from the rear case, and an anti-glare film is arranged on the surface of the cover plate away from the rear case.

[0054] Figure 1 FIG. is a schematic structural view of the rear case according to an embodiment of the present invention, showing a rear view of the rear case. As Figure 1 shown, the main structure of the rear case 10 includes a back plate 11 and a frame edge 12. The back plate 11 is in the shape of a rectangular plate, and the frame edge 12 is in the shape of a rectangular frame structure. The frame edge 12 has two pairs of frame walls, and the two pairs of frame walls are respectively arranged on two pairs of edges of the back plate 11. The back plate 11 and the frame edge 12 are an integral metal structure. The rectangular plate-shaped back plate 11 and the rectangular frame-shaped frame edge 12 together form a reverse-cover type housing structure with a receiving space. Among them, an opening 13 is formed on one frame wall of the frame edge 12. As Figure 1 shown, in the embodiment of the present invention, the frame edge 12 includes a pair of long frame walls and a pair of short frame walls. The opening 13 is formed on one long frame wall. The depth of the opening 13 is less than the height of the long frame wall, and the length of the opening 13 is less than the length of the long frame wall. Considering that the reverse-cover type metal housing structure of the rear case has a shielding effect on the antenna signal, affecting the normal transmission and reception of the antenna signal (such as WIFI signal), in the embodiment of the present invention, an opening is formed on the frame edge of the rear case, and the opening is filled with a first frame body. By using the characteristic that the first frame body made of a non-metallic material does not shield the antenna signal, an antenna signal transmission channel is formed, increasing the receiving area of the antenna signal and effectively ensuring the normal transmission and reception of the antenna signal. Since the opening is filled with the first frame body, on one side of the rear case where the opening is formed, the side wall is composed of the frame edge where the opening is formed and the first frame body filled in the opening, and it is still a complete side wall in appearance. Therefore, the rear case is still a complete housing structure, ensuring the integrity of the appearance of the rear case while effectively strengthening the antenna signal. In actual implementation, according to the number of antennas set, the set positions, and the communication requirements, the opening can be formed on one long frame wall and / or one short frame wall, or can be formed on a pair of long frame walls and / or a pair of short frame walls.

[0055] Among them, the four corners of the rectangular plate-shaped back plate 11 are set to be smooth arcs, and the four corners of the rectangular frame-shaped frame edge 12 are also set to be corresponding arcs to increase the overall aesthetic feeling. In addition, at least one through hole is formed on the back plate 11 for exposing the camera assembly, and a plurality of through holes are respectively formed on a pair of short frame walls of the frame edge 12 for respectively exposing the corresponding devices and function keys of the electronic terminal. As Figure 1 shown, in combination with Figures 9 to 11, in the embodiment of the present invention, a camera hole a for exposing the camera assembly 118 is provided on the back plate 11, a first speaker hole b for exposing the first speaker assembly 110, a first button hole c and a second button hole d for exposing the button assemblies 108 and 109 are provided on one short frame wall of the frame edge 12, and a second speaker hole for exposing the second speaker assembly 111, an interface hole for exposing the USB interface assembly, and a microphone hole for exposing the microphone assembly 112 are provided on the other short frame wall of the frame edge 12. In actual implementation, the number, positions, and sizes of the camera hole, speaker holes, interface hole, button holes, and microphone hole can be set according to the functions of the electronic terminal and the specifications of the corresponding components, etc. The functions of the corresponding through holes are only an exemplary illustration, and the embodiments of the present invention do not make specific limitations here.

[0056] In the embodiment of the present invention, by providing a rear shell with an integrated metal overhanging housing structure, the overall strength of the electronic terminal is maximally enhanced, and the reliability of the overall structure of the whole machine is improved. At the same time, by providing openings on the frame edge of the rear shell, the normal transmission and reception of antenna signals are effectively ensured, and on the premise of strengthening the antenna signals, the integrity of the appearance of the rear shell is ensured.

[0057] Figure 2 It is a structural schematic diagram of the first frame body in the embodiment of the present invention, showing a view of the first frame body from the rear (viewing the first frame body from the side of the rear shell). Figure 3 It is another structural schematic diagram of the first frame body in the embodiment of the present invention, showing a view of the first frame body from the front (viewing the first frame body from the side of the display module). As Figure 2 and Figure 3As shown in the figure, the main structure of the first housing 20 includes a first housing plate 21 and a first housing edge 22. The first housing plate 21 is in the shape of a rectangular plate, and the first housing edge 22 is in the structure of a rectangular frame. The first housing edge 22 is arranged at the edge of the first housing plate 21. The first housing plate 21 and the first housing edge 22 are of an integral non-metallic structure, together forming a setting space for setting electronic devices. Among them, the first housing 20 can be made of non-conductive materials such as plastics, resins, ceramics or other polymers, and corresponding partition walls, mounting holes, mounting seats and other components are formed through processes such as injection molding or machining. In the embodiment of the present invention, the first housing 20 is fixed in the accommodation space of the rear housing 10 by a hot pressing process. By assembling the rear housing 10 and the first housing 20 by the hot pressing process, the processing difficulty and cost of the rear housing 10 can be reduced, and the assembly process is simplified. Usually, through fixing methods such as snap connection and screw connection, corresponding connection structures need to be arranged in the rear housing, and a relatively high processing accuracy is required to achieve the cooperation with the first housing, resulting in a relatively high processing cost and difficulty, and there are many processes such as alignment and connection in the assembly process, and the assembly time is long. In the embodiment of the present invention, by adopting the hot pressing process, there is no need to arrange a connection structure in the accommodation space of the rear housing, nor is a too high processing accuracy required. The assembly is completed by one hot pressing, reducing the processing difficulty and cost of the rear housing and simplifying the assembly process. At the same time, in the embodiment of the present invention, by assembling the rear housing and the first housing by the hot pressing process, the rear housing and the first housing are closely attached, increasing the structural strength of the first housing and improving the reliability of the electronic devices on the first housing.

[0058] As Figure 2 and Figure 3 shown, the first housing 20 is further provided with an auxiliary housing wall 23. The auxiliary housing wall 23 is arranged on the side wall of a first housing edge 22 away from the outside of the setting space, corresponding to the position of the opening 13 of the rear housing 10. The length and width of the auxiliary housing wall 23 are the same as the length and width of the opening 13. When the first housing 20 is fixed in the accommodation space of the rear housing 10, the auxiliary housing wall 23 just fills the opening 13 of the rear housing 10, and the housing edge 12 where the opening 13 is located and the auxiliary housing wall 23 together form a complete side wall. In addition, the first housing 20 is further provided with a first engaging portion, and the first engaging portion includes a plurality of engaging blocks 24. The engaging blocks 24 are all arranged on the inner side wall of the first housing edge 22 facing the setting space, and the plurality of engaging blocks 24 are arranged at intervals for engaging with the second housing. Among them, the auxiliary housing wall 23 and the engaging blocks 24 can be of an integral structure with the first housing plate 21 and the first housing edge 22 and are formed simultaneously through processes such as injection molding.

[0059] As Figure 2 and Figure 3 shown, in combination with Figures 9 to 11, a plurality of mounting holes are formed in the first frame plate 21. The plurality of mounting holes may be: a mounting hole e for fixing the first circuit board, a mounting hole f for fixing the second circuit board, a mounting hole g for fixing the battery assembly 117, a mounting hole h for fixing the camera assembly 118, etc. Among them, the first circuit board is the circuit board of the first speaker assembly 110, and the second circuit board is the circuit board of the second speaker assembly 111. In addition, at positions corresponding to the plurality of through holes on the rear case 10 that expose the speaker assembly, the interface assembly, the button assembly, etc., a plurality of mounting holes for fixing the first speaker assembly 110, the button assemblies 108, 109, the second speaker assembly 111, the USB interface, and the microphone assembly 112 are also formed on the first frame edge 22. In addition, a plurality of screw holes are formed in the first frame plate 21 for fixing the interface assembly 121, the antenna assembly 122, the main board assembly 123, etc. Among them, the antenna assembly 122 is disposed on the main board assembly 123, and the antenna assembly 122 is disposed on one side of the main board assembly 123 adjacent to the opening of the rear case. In actual implementation, the number, position, and size of the plurality of mounting holes can be set according to the specifications of the corresponding electronic components of the electronic terminal, and the fixing method can be welding, clamping, bonding, screwing, or other methods, which are not specifically limited in the embodiments of the present invention.

[0060] Figure 4 FIG. is a schematic structural diagram of a second housing according to an embodiment of the present invention, showing a rear view of the second housing (viewing the second housing from one side of the first housing). Figure 5 FIG. is another schematic structural diagram of a second housing according to an embodiment of the present invention, showing a front view of the second housing (viewing the second housing from the side of the display module). As Figure 4 and Figure 5 shown, the main body structure of the second housing 30 is a rectangular support 31 made of a non-metallic material. The support 31 is located between the first housing 20 and the display module, and the support portion 31 is configured to support the display module. A connecting portion 32 is provided on the surface of the support 31 facing the first housing 20, and an extension portion 33 is provided on the surface of the support 31 facing the display module. The second housing 30 can be an integral structure formed by injection molding or processing using a non-conductive material such as plastic, resin, ceramic, or other polymers.

[0061] Among them, the connecting portion 32 is arranged on the side of the support body 31 facing the first frame body 20, and is a strip extending along the edge of the support body 31. The plane of the connecting portion 32 is perpendicular to the plane of the support body 31. The width direction of the connecting portion 32 extends along the direction perpendicular to the plane of the support body 31, and the length direction of the connecting portion 32 extends along the edge direction of the support body 31. A second engaging portion is arranged on the connecting portion 32. The second engaging portion includes a plurality of card slots 34, and the plurality of card slots 34 are arranged at intervals and correspond to the positions of a plurality of card blocks 24 on the first frame edge 22 respectively. The length and width of the card slots 34 are adapted to the length and width of the card blocks 24. The first frame body 20 and the second frame body 30 are engaged and connected through the first engaging portion and the second engaging portion. When installing the second frame body 30, the plurality of card slots 34 of the connecting portion 32 on the second frame body 30 are clamped on the plurality of card blocks 24 of the first frame body 20, and the support body 31 of the second frame body 30 is closely attached to the first frame plate 21 of the first frame body 20, connecting the second frame body 30 and the first frame body 20 into one body, improving the connection reliability and the overall structural strength of the second frame body 30 and the first frame body 20.

[0062] Among them, on the side of the support body 31 facing the display module, the extending portion 33 is a flanging structure formed at the edge of the support body 31. The extending portion 33 is arranged at the edge of the support portion 31 and is configured to isolate the display module and the rear shell. Figure 6 It is a schematic structural diagram of the extending portion in the embodiment of the present invention. As Figure 6As shown in the figure, at the end of the support body 31, the extension part 33 includes a vertical part 331 perpendicular to the plane of the support body 31 and a horizontal part 332 parallel to the plane of the support body 31. The first end of the vertical part 331 is connected to the end of the support body 31, and the second end extends outward from the support body 31 (towards the display module) in a direction perpendicular to the plane of the second housing 30. The first end of the horizontal part 332 is connected to the second end of the vertical part 331, and the second end of the horizontal part 332 extends outward from the support body 31 (away from the support body 31) in a direction parallel to the plane of the second housing 30, forming an extension structure at the edge of the support body 31. At the end of the support body 31, the extension part 33 forms at least two end faces, namely a horizontal end face A1 and a vertical end face B1. When installing the second housing 30, the end of the support body 31 abuts against the inner surface of the frame edge 12 of the rear housing 10, and the horizontal end face A1 (the lower surface of the horizontal part 332) presses against the upper end part of the frame edge 12 of the rear housing 10. At the same time, the vertical end face B1 and the upper surface of the support body 31 form a bearing space for setting the display module. In this way, the extension part 33 of the second housing 30 is arranged between the rear housing 10 and the display module, forming a layout in which the rear housing 10 is isolated from the display module. In addition, the horizontal part 332 also has a first side face A2 and a second side face B2. The first side face A2 is flush with the outer surface of the frame edge 12 of the rear housing 10, and the second side face B2 is flush with the outer surface of the second end of the vertical part 331. The first side face A2 is connected to the second side face B2 through a curved surface. In fact, the first side face A2 and the second side face B2 are the first side face and the second side face of the extension part 33. Among them, the first side face A2 and the second side face B2 are perpendicular to each other. In this way, the first side face A2 of the horizontal part 332 (extension part 33) is flush with the outer surface of the frame edge 12 of the rear housing 10, forming a complete side wall in appearance, and the second side face B2 of the horizontal part 332 (extension part 33) is flush with the outer surface of the display module, forming a complete upper surface in appearance.

[0063] In the embodiment of the present invention, an extension structure is formed by the second housing, which can effectively prevent the display module from directly contacting the rear housing made of metal material. On the one hand, it can improve the maintainability, and on the other hand, it can improve the anti-breakage performance. Specifically, during maintenance, since the display module contacts the second housing made of non-metallic material, the display module can be quickly removed by utilizing the deformation of the non-metallic material, which will neither damage the display module nor damage the rear housing. When the whole electronic terminal drops, the impact borne by the rear housing can be maximally absorbed by the second housing made of non-metallic material. The second housing can play a good buffering role and effectively prevent the display module from being damaged.

[0064] Figure 7 It is a schematic structural diagram of the display module according to the embodiment of the present invention, showing a view of the display module from the rear (viewing the display module from the side of the second housing). As Figure 7As shown, the main structure of the display module (TLCM) 40 includes a stacked touch component (TP) 41 and a display component (LCD module, LCM) 42. The touch component 41 is disposed on the surface of the display component 42 away from the rear case, and the driving circuit is disposed on the surface of the display module 42 facing the rear case. In the embodiment of the present invention, a cover plate is disposed on the surface of the touch panel 41 away from the rear case, and a polarizing surface treatment (AG) matte film is disposed on the surface of the cover plate away from the rear case, which can effectively prevent glare, enhance the display effect of the picture, and at the same time has the effects of anti-fouling and explosion-proof. In actual implementation, the matte film can be attached to the surface of the cover plate by an optical adhesive (OCA) attachment process. The display module in the embodiment of the present invention can adopt a touch display screen with mature related technologies, and the display component can also be an organic light-emitting diode (OLED), which will not be elaborated here.

[0065] Figure 8 This is a schematic diagram of the fixation of the rear case, the first and second frames, and the display module in the embodiment of the present invention. As Figure 8 shown, the first frame 20 is fixed in the rear case 10 by a hot pressing process. The first frame plate of the first frame 20 is closely attached to the back plate of the rear case 10, and the first frame edge 22 of the first frame 20 is closely attached to the frame edge of the rear case 10. The second frame 30 is fixed on the first frame 20 in a clamping manner through a first clamping portion and a second clamping portion. Among them, the extension portion 33 of the second frame 30 is pressed on the top of the rear case 10, and the card slot 34 of the second frame 30 is clamped on the block 24 of the first frame 20.
