[0032] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0033] As shown in the drawings, the middle frame assembly of the embodiment of the present application comprises a frame body 1, a radiator 2, a first cladding layer 3 and a second cladding layer 4. Figure 1

[0034] ​The frame body 1 can include a flat plate portion and a frame portion. The flat plate portion can generally be rectangular, and the frame portion can be located on the outer periphery of the flat plate portion and extend along the circumference of the flat plate portion. The frame body 1 can be made of metal, specifically aluminum.

[0035] Radiator 2 is connected to the periphery of frame body 1 and arranged at intervals from frame body 1. For example, radiator 2 can be integrally formed into the edge portion of frame body 1. Radiator 2 can be rectangular in shape. In use, radiator 2 can function as an antenna, thereby enabling the transmission and reception of communication signals. Figure 1 As shown, the radiator 2 can generally extend along the left and right direction, and in the inward and outward directions of the frame body 1, the radiator 2 can be located outside the frame portion of the frame body 1 and spaced apart from the frame portion.

[0036] The first covering layer 3 is disposed on the outer periphery of the frame body 1, and at least part of the radiators 2 are located within the first covering layer 3. For example, the material of the first covering layer 3 can be hard plastic, the first covering layer 3 can cover the outer periphery of the frame body 1, and the first covering layer 3 can be connected and fixed to the frame part by injection molding.

[0037] like Figure 1 As shown, the radiator 2 can be injection molded and fixed within the first cladding layer 3. Specifically, the gap between the radiator 2 and the frame portion can form an antenna clearance, a portion of the first cladding layer 3 can fill this antenna clearance, and another portion of the first cladding layer 3 can cover the outer surface of the radiator 2. This achieves the connection and fixation between the first cladding layer 3 and the frame body 1 and the radiator 2.

[0038] The second coating layer 4 is disposed on the outer periphery of the first coating layer 3, and the hardness of the second coating layer 4 is less than that of the first coating layer 3. For example, the second coating layer 4 can be a soft rubber, such as... Figure 1 As shown, the second covering layer 4 can be attached to the outer wall surface of the first covering layer 3. The material of the second covering layer 4 is softer than that of the first covering layer 3, so that the added second covering layer 4 can absorb assembly tolerances and provide cushioning.

[0039] It should be noted that the flat plate portion of the frame body 1 can be rectangular, and each of the four edges of the flat plate portion can be provided with a border portion. The outer side of each border portion can be provided with the first covering layer 3 and the second covering layer 4.

[0040] The middle frame assembly of this utility model has a soft second covering layer 4 on its outer side. The second covering layer 4 has a certain elastic deformation property, which enables the middle frame assembly to absorb assembly tolerances and also provides a certain buffering effect, thereby improving the assembly compatibility with other components.

[0041] Secondly, compared with the case that the second coating layer 4 is directly attached on the frame body 1, the first coating layer 3 is arranged between the second coating layer 4 and the frame body 1, the first coating layer 3 can play a buffering role of combination, that is, the first coating layer 3 and the frame body 1 and the second coating layer 4 can have good adhesive bonding effect, thereby ensuring the overall connection strength of the middle frame assembly.

[0042] In some embodiments, the first coating layer 3 is hard glue, and the second coating layer 4 is soft glue. The hard glue can be polybutylene terephthalate, polycarbonate, etc. The soft glue can be thermoplastic polyurethane elastomer (also known as thermoplastic polyurethane rubber), etc. Thus, the use needs of combination and elastic buffering are fully met.

[0043] In some embodiments, the inner side of the second coating layer 4 is provided with an annular portion 41, and the annular portion 41 is embedded in the first coating layer 3. For example, as shown in Figure 2 The annular portion 41 can be integrally formed on the inner side wall of the second coating layer 4. The annular portion 41 can be generally square ring-shaped. The first coating layer 3 can be provided with a groove 45 or the like structure, and the annular portion 41 can be injection molded in the groove 45 of the first coating layer 3.

[0044] The annular portion 41 can enhance the adhesive effect of the second coating layer 4 and the first coating layer 3, that is, the annular portion 41 can simultaneously realize the close combination and adhesion of the first coating layer 3 in the up-down, left-right, front-back three directions, and fully ensure the glue grabbing effect and the structural strength of the combination of the first coating layer 3 and the first coating layer 3.

[0045] In some embodiments, the inner side of the second coating layer 4 is provided with a first rib 411, a second rib 412 and a third rib 413. The first rib 411 and the second rib 412 extend along the circumference of the frame body 1 and are arranged in the thickness direction of the frame body 1. The third rib 413 extends along the thickness direction and is connected between the first rib 411 and the second rib 412. Part of the first rib 411, part of the second rib 412 and the third rib 413 form the annular portion 41.

[0046] For example, as shown in Figure 2 The first rib 411, the second rib 412 and the third rib 413 can be integrally formed on the inner side of the second coating layer 4. The first rib 411 and the second rib 412 can be in strip-shaped structure, and the first rib 411 and the second rib 412 can extend along the left-right direction and be arranged in the up-down direction.

[0047] The third rib 413 can be generally cylindrical, and can extend along the up-down direction. The top end of the third rib 413 can be connected to the first rib 411, and the bottom end of the third rib 413 can be connected to the second rib 412. The third rib 413 can be spaced apart from the inner wall surface of the second cover layer 4 in the inner-outer direction. In this way, the annular portion 41 can be conveniently formed.

[0048] It should be noted that the annular portion 41 can be provided in multiple numbers, and the multiple annular portions 41 can be arranged at intervals along the extension direction of the second cover layer 4, so as to ensure the strength of the combination of the second cover layer 4 and the first cover layer 3 at each position.

[0049] In some embodiments, the end of the third rib 413 is provided with an undercut 4131, which protrudes from the first rib 411 in the thickness direction and is embedded in the first cover layer 3. For example, as shown in Figure 3 the third rib 413 can extend along the up-down direction. The undercut 4131 can be a part of the top end of the third rib 413, and specifically can be a part of the third rib 413 that protrudes upward from the first rib 411. The undercut 4131 can be fitted in the first cover layer 3, so as to further improve the adhesion effect of the second cover layer 4 and the first cover layer 3.

[0050] In some embodiments, the second cover layer 4 includes a first extension segment 42 and a second extension segment 43 extending along the circumference of the frame body 1. In the thickness direction of the frame body 1, the width dimension of the first extension segment 42 is smaller than the width dimension of the second extension segment 43, so as to form an avoidance slot 44 on one side of the first extension segment 42 for avoiding the keys.

[0051] For example, as shown in Figure 4 the second cover layer 4 can extend along the left-right direction. The second cover layer 4 can include one first extension segment 42 and two second extension segments 43, and the first extension segment 42 can be connected between the two second extension segments 43.

[0052] The thickness direction of the frame body 1 can be the up-down direction, as shown in Figure 4 the width dimension of the first extension segment 42 can be dimension M, and the width dimension of the second extension segment 43 can be dimension N. The dimension M is smaller than the dimension N, and the top side of the first extension segment 42 and the top side of the second extension segment 43 can be generally arranged in a flush manner.

[0053] As shown in Figure 4 Since the first extension segment 42 is generally narrow, a notch-like design, i.e., the avoidance slot 44, can be formed below the first extension segment 42. During assembly, the keys can be assembled in the avoidance slot 44, so as to avoid the interference between the first cover layer 3 and the keys during assembly.

[0054] In some embodiments, the inner side of the end of the first extension section 42 connected with the second extension section 43 is provided with a plurality of fourth ribs 421, the plurality of fourth ribs 421 are arranged at intervals along the extension direction of the first extension section 42, the fourth ribs 421 are embedded in the first cladding layer 3, and the length dimension of the plurality of fourth ribs 421 in the thickness direction has an increasing trend along the direction towards the second extension section 43.

[0055] For example, as shown in Figure 5 the extension direction of the first extension section 42 can be the left-right direction, the fourth ribs 421 can be generally cylindrical, the axial direction of the fourth ribs 421 can be the up-down direction, and the plurality of fourth ribs 421 can be arranged at intervals along the left-right direction.

[0056] The second extension section 43 can be connected to the right side of the first extension section 42, and the length dimension of several fourth ribs 421 on the first extension section 42 adjacent to the second extension section 43 can gradually increase along the direction from left to right. For example, as shown in Figure 5 the end of the second extension section 43 adjacent to the second extension section 43 can be provided with two fourth ribs 421, and the length dimension of the fourth rib 421 on the left side can be three-fourths of the length dimension of the fourth rib 421 on the right side, that is, the fourth rib 421 on the left side can be designed as a three-fourth hole soft rubber grip, and the fourth rib 421 on the right side can be designed as a full hole soft rubber grip. In this way, the structural strength of the adhesion of the connection between the first extension section 42 and the second extension section 43 is fully ensured.

[0057] In some embodiments, the inner side of the end of the second extension section 43 connected with the first extension section 42 is provided with a boss 431, and the boss 431 is embedded in the first cladding layer 3. For example, as shown in Figure 5 the boss 431 can be generally in the form of a nail structure, the axial direction of the boss 431 can be along the inner-outer direction, the first cladding layer 3 can be provided with a stepped groove, and the boss 431 can be fitted in the stepped groove, so as to further improve the structural strength of the adhesion of the connection between the first extension section 42 and the second extension section 43.

[0058] In some embodiments, the inner side of the end of the second extension section 43 connected with the first extension section 42 is provided with a fifth rib 432 and a sixth rib 433, the fifth rib 432 and the sixth rib 433 are arranged along the thickness direction, the fifth rib 432 and the sixth rib 433 are arranged in a staggered manner in the circumferential direction of the frame body 1 to form a Z-shaped structure, and the Z-shaped structure is embedded in the first cladding layer 3.

[0059] For example, as shown in Figure 5As shown, the fifth rib 432 and the sixth rib 433 can both be generally cylindrical and can both extend along the up-down direction, wherein the length dimension of the fifth rib 432 can be greater than the length dimension of the sixth rib 433. And in the left-right direction, the fifth rib 432 and the sixth rib 433 can be arranged staggeredly, wherein the fifth rib 432 can be located at the right side of the sixth rib 433. Thus, the fifth rib 432 and the sixth rib 433 as a whole can form a Z-shaped structure, that is Figure 5 As shown by the structure indicated by the dashed line A, during processing, the Z-shaped structure as a whole can also be embedded in the first cladding layer 3, thereby further improving the adhesion strength of the connecting portion of the first extending section 42 and the second extending section 43.

During processing, the U-shaped structure as a whole can also be embedded in the first cladding layer 3, thereby further improving the adhesion strength of the connecting portion of the first extending section 42 and the second extending section 43.

[0062] In some embodiments, the outer circumferential side of the second cladding layer 4 is provided with a plurality of grooves 45, the plurality of grooves 45 extend along the circumference of the frame body 1 and are arranged at intervals in the thickness direction of the frame body 1.
