[0052] The first middle frame 100 is provided with a first receiving groove 101, and the second middle frame 110 is provided with a second receiving groove 120. The first middle frame 100 and the second middle frame 110 are arranged side by side, and the first receiving groove 101 and the second receiving groove 120 are communicated, and together form a receiving groove 130. The rotating shaft 540 is installed in the receiving groove 130, and is connected to the first middle frame 100 and the second middle frame 110 to realize the rotation connection between the first middle frame 100 and the second middle frame 110. When the first middle frame 100 rotates, the second middle frame 110 is driven to rotate through the rotating shaft 540, so as to realize the folding or unfolding of the electronic device 500.

[0053] The display screen 400 includes a first part 410, a second part 420 and a foldable part 430.

[0061] Please also read Figure 7 , Figure 7 yes Figure 6 The enlarged structural diagram of the frame 10 in area A is shown.

[0062] The first mounting frame 30 includes a body 31 and a rib 32. The body 31 is arranged side by side with the middle plate 20 along the X direction and is fixedly connected to the fourth side portion 27 of the middle plate 20. The body 31 is provided with a first mounting groove 33. The first mounting groove 33 is L-shaped. The extension direction of the first mounting groove 33 is parallel to the Y direction. The first mounting groove 33 includes a first bottom wall 331 and a first side wall 332. The first side wall 332 is fixedly connected to the first bottom wall 331. In this embodiment, the first side wall 332 is parallel to the YZ plane. There may also be a small angle between the first side wall 332 and the YZ plane, for example, 5 degrees or 10 degrees. In this embodiment, the first side wall 332 is vertically connected to the first bottom wall 331. In other embodiments, the angle between the first side wall 332 and the first bottom wall 331 may also be slightly greater than 90 degrees, or slightly less than 90 degrees.

[0063] There are multiple groups of convex ribs 32. Multiple groups of convex ribs 32 are convexly arranged on the first side wall 332 and are spaced apart along the Y direction on the first side wall 332. Each group of convex ribs 32 includes a first convex rib 34 and a second convex rib 35. The first convex rib 34 includes a first surface 341, a first side surface 343, a second side surface 344, a third side surface 345 and a fourth side surface 346. The first surface 341 is a surface of the first convex rib 34 away from the first side wall 332. The first side surface 343 and the second side surface 344 are arranged opposite to each other and are respectively located on opposite sides of the Y direction, and the third side surface 345 and the fourth side surface 346 are arranged opposite to each other and are respectively located on opposite sides of the Z direction. The first side surface 343, the third side surface 345, the second side surface 344 and the fourth side surface 346 are connected end to end and are all connected between the first surface 341 and the first side wall 332.

[0064] The first convex rib 34 is provided with a first limiting groove 36. The first limiting groove 36 includes a first sub-limiting groove 361 and a second sub-limiting groove 362. From the first surface 341 to the first side wall 332, the first side surface 343 is recessed toward the first convex rib 34, and a first sub-limiting groove 361 is formed between the first side wall 332. From the first surface 341 to the first side wall 332, the second side surface 344 is recessed toward the first convex rib 34, and a second sub-limiting groove 362 is formed between the first side wall 332. It can be understood that the edge portion of the first convex rib 34 close to the first side surface 343 is the groove wall of the first sub-limiting groove 361, and the edge portion of the first convex rib 34 close to the second side surface 344 is the groove wall of the second sub-limiting groove 362. The groove wall of the first sub-limiting groove 361 and the groove wall of the second sub-limiting groove 362 are both opposite to the first side wall 332.

[0065] In this embodiment, the first side surface 343 and the second side surface 344 are both curved surfaces. It is understandable that by setting a chamfer on the first side surface 343, the first sub-limiting groove 361 can be obtained. By setting a chamfer on the second side surface 344, the second sub-limiting groove 362 can be obtained. The cross section of the first rib 34 along the XY plane is roughly trapezoidal. In other embodiments, the first side surface 343 and the second side surface 344 can also be inclined surfaces, and the cross section of the first rib 34 along the XY plane is trapezoidal. Alternatively, the first side surface 343 is a curved surface, and the second side surface 344 is an inclined surface; or the first side surface 343 is an inclined surface, and the second side surface 344 is a curved surface. The first sub-limiting groove 361 and the second sub-limiting groove 362 are both used to clamp and connect with the rubber bag 40 to prevent the rubber bag 40 from detaching from the frame 10 along the X direction.

[0066] In one embodiment, the first limiting groove 36 may further include a fifth sub-limiting groove and a sixth sub-limiting groove (not shown). From the first surface 341 to the first side wall 332, the third side surface 345 is recessed toward the first convex rib 34, and a fifth sub-limiting groove is formed between the third side surface 345 and the first side wall 332. From the first surface 341 to the first side wall 332, the fourth side surface 346 is recessed toward the first convex rib 34, and a sixth sub-limiting groove is formed between the fourth side surface 346 and the first side wall 332.

[0084] It is understandable that after the rubber coating 40 is formed on the frame 10, the outer side surface of the first frame 41, the outer side surface of the second frame 42 and the outer side surface of the third frame 43 are exposed from the side surface of the electronic device 500, which is the frame of the electronic device 500. The second installation groove 501 is the first receiving groove 101 of the electronic device 500, which is used to install the rotating shaft 540 of the electronic device 500.

[0085] It should be noted that the rubber package 40 is formed on the frame 10 by injection molding, and the above-mentioned connection relationships are directly formed during injection molding. The specific processing method is described in detail below.

[0086] The middle frame 200 in this embodiment is composed of a frame body 10 made of metal material and a plastic coating 40 made of plastic material. Compared with the pure metal middle frame 200, the middle frame 200 in this embodiment is lighter in weight and can reduce weight, which is conducive to achieving lightweight electronic equipment 500 and improving user experience. For example, compared with the profile aluminum middle frame 200, the middle frame 200 provided in this embodiment can achieve a weight reduction of about 11%. In addition, in this embodiment, by coating the plastic coating 40 on the outer surface of the metal frame body 10, the frame body 10 can be protected to prevent the middle frame 200 from being corroded by salt spray and the like, thereby improving the corrosion resistance of the middle frame 200, so that the electronic device 500 can be used stably without failure in a corrosive environment, thereby improving the durability of the electronic device 500.

[0087] In the case where the protection effect and structural strength of the shaft area of ​​the middle frame 200 can be achieved, the middle frame 200 provided in this embodiment has a smaller space requirement. For example, in this embodiment, when the thickness of the rubber coating 40 is 0.25 mm and the thickness of the frame 10 is 0.65 mm, the protection effect and structural strength of the shaft area can be achieved, so that the electronic device 500 can be made thinner and lighter. It should be explained that the "shaft area" mentioned here is the area where the rotating shaft 540 is installed, that is, the area where the first installation frame 30 and the second installation frame 50 are located.

[0088] In this embodiment, by setting the first limiting groove 36, the second limiting groove 37 and the glue pulling groove 38 in the first installation frame 30, when the glue bag 40 is formed on the surface of the frame body 10, the first limiting groove 36 is correspondingly formed with the first clamping portion 55, and the first limiting groove 36 is clamped and connected with the first clamping portion 55 in a direction perpendicular to the first side wall 332 (X direction), the second limiting groove 37 is correspondingly formed with the second clamping portion 58, the second limiting groove 37 is clamped and connected with the second clamping portion 58 in the X direction, and the glue pulling groove 38 is correspondingly formed with a protrusion 59, and the glue pulling The groove 38 and the protrusion 59 are clamped and connected in the width direction (Z direction) of the first side wall 332. The first limiting groove 36 and the second limiting groove 37 limit the rubber bag 40 in the X direction, which can prevent the rubber bag 40 from being separated from the frame 10 in the X direction. The rubber pulling groove 38 limits the rubber bag 40 in the Z direction, which can prevent the rubber bag 40 from being separated from the frame 10 in the Z direction, thereby improving the stability of the connection between the rubber bag 40 and the frame 10, preventing the rubber bag 40 from being separated from the frame 10 in the axial area, and achieving the rubber pulling effect between the frame 10 and the rubber bag 40. It should be explained that the "rubber pulling effect" mentioned here refers to the effect that the rubber bag 40 is not easy to be separated from the frame 10 when the action is applied to the rubber bag 40.

[0089] Among them, by setting the first rib 34 and the first limiting groove 36 on the first installation frame 30, when the rubber bag 40 is formed on the surface of the frame body 10, the outer surface of the first rib 34 forms a first groove 53 correspondingly, and the first clamping portion 55 is formed correspondingly in the first limiting groove 36, so that when a force is applied to the rubber bag 40 in a direction perpendicular to the first side wall 332, that is, in the X direction, the first clamping portion 55 abuts against the groove wall of the first limiting groove 36, and the groove wall of the first limiting groove 36 limits the rubber bag 40, thereby preventing the rubber bag 40 from detaching from the frame body 10 in the X direction. At the same time, in this embodiment, by setting a plurality of first ribs 34 along the Y direction on the first side wall 332 and forming a plurality of first limiting grooves 36, and setting a plurality of first grooves 53 along the Y direction on the second side wall 521, and forming a plurality of first clamping portions 55, the frame 10 can limit the rubber bag 40 at multiple positions in the Y direction, thereby further preventing the rubber bag 40 from detaching from the rubber bag 40 in a direction perpendicular to the first side wall 332, and further improving the stability of the connection between the rubber bag 40 and the frame 10.

[0090] Furthermore, by providing the second rib 35 and the second limiting groove 37 in the first mounting frame 30, when the rubber bag 40 is formed on the surface of the frame body 10, the outer surface of the second rib forms a second groove 56 correspondingly, and the second clamping portion 58 is formed correspondingly in the second limiting groove 37, so that when a force is applied to the rubber bag 40 in a direction perpendicular to the first side wall 332, the second clamping portion 58 abuts against the groove wall of the second limiting groove 37, and the groove wall of the second limiting groove 37 further limits the rubber bag 40, thereby further improving the stability of the connection between the rubber bag 40 and the frame body 10, and further preventing the rubber bag 40 from detaching from the frame body 10 in the X direction. At the same time, in this embodiment, by setting a plurality of second ribs 35 along the Y direction on the first side wall 332 and forming a plurality of second limiting grooves 37, and setting a plurality of second grooves 56 along the Y direction on the second side wall 521, and forming a plurality of second clamping portions 58, the frame 10 can limit the rubber bag 40 at multiple positions in the Y direction, thereby further preventing the rubber bag 40 from detaching from the rubber bag 40 in a direction perpendicular to the first side wall 332, and further improving the stability of the connection between the rubber bag 40 and the frame 10.

[0091] In this embodiment, by providing the rubber drawing groove 38 in the frame 10, when the rubber bag 40 is formed on the surface of the frame 10, a protrusion 59 is correspondingly formed in the rubber drawing groove 38, so that when a force is applied to the rubber bag 40 along the Z direction, the abutting wall of the rubber drawing groove 38 abuts the protrusion 59, and the abutting wall plays a limiting role on the rubber bag 40, thereby preventing the rubber bag 40 from being separated from the frame 10 along the Z direction. For example, when a force is applied to the rubber bag 40 along the negative direction of the Z axis, the protrusion 59 abuts the first abutting wall 381, and the first abutting wall 381 plays a limiting role on the protrusion 59, thereby preventing the rubber bag 40 from being separated from the frame 10 along the negative direction of the Z axis; when a force is applied to the rubber bag 40 along the positive direction of the Z axis, the protrusion 59 abuts the second abutting wall 382, ​​and the second abutting wall 382 plays a limiting role on the protrusion 59, thereby preventing the rubber bag 40 from being separated from the frame 10 along the positive direction of the Z axis.

[0092] At the same time, in this embodiment, by setting a plurality of glue pulling grooves 38 along the Y direction on the first side wall 332 and setting a plurality of protrusions 59 along the Y direction on the second side wall 521, the frame 10 can limit the rubber bag 40 at multiple positions in the Y direction, thereby further preventing the rubber bag 40 from detaching from the rubber bag 40 along the width direction of the first side wall 332, and further improving the stability of the connection between the rubber bag 40 and the frame 10.

[0093] In addition, in this embodiment, by providing a slot 39 on the first side wall 332, when the rubber bag 40 is formed on the surface of the frame 10, a corresponding holding protrusion 503 is formed in the slot 39, so that when a force is applied to the rubber bag 40 in a direction perpendicular to the first side wall 332, that is, when a force is applied to the rubber bag 40 in the X direction, the holding protrusion 503 abuts against the slot wall of the slot 39, and the slot wall of the slot 39 limits the holding protrusion 503, thereby further preventing the rubber bag 40 from detaching from the frame 10 in the X direction, and further improving the stability of the connection between the rubber bag 40 and the frame 10.

[0094] See also Fig.11 , Fig.11 yes Figure 4 The manufacturing flow chart of the first middle frame 100 is shown.

The two side surfaces are respectively recessed toward the convex rib 32, and limiting grooves are formed between the two side surfaces and the first side wall. In this embodiment, the groove wall of the limiting groove is a curved surface. In other embodiments, the groove wall of the limiting groove can also be an inclined surface.

[0101] In S2, a CNC (numerical control machine) is used to cut the surface of the basic convex rib to obtain a glue drawing groove 38. After cutting, the basic convex rib is divided into two parts, namely a first convex rib 34 and a second convex rib 35, thereby obtaining a frame 10. The first convex rib 34 and the second convex rib 35 are arranged side by side and spaced apart along the width direction of the first side wall. Among them, a first limiting groove 36 is formed between the side surface of the first convex rib 34 and the first side wall, and a second limiting groove 37 is formed between the side surface of the second convex rib 35 and the first side wall.

In addition, by forming the encapsulation 40 by injection molding on the surface of the frame 10, the frame 10 can be protected to prevent the middle frame 200 from being corroded by salt spray, etc., thereby improving the corrosion resistance of the middle frame 200, so that the electronic device 500 can be stably used without failure in a corrosive environment, thereby improving the durability of the electronic device 500.
