The back cover 300 includes a first back cover 310 and a second back cover 320. The first back cover 310 is mounted on the first middle frame 100 and together they form the first housing 520. The second back cover 320 is mounted on the second middle frame 110 and together they form the second housing 530. In other embodiments, the middle frame 200 and the back cover 300 may be a single piece. That is, the first back cover 310 and the first middle frame 100 are a single piece, and the second back cover 320 and the second middle frame 110 are a single piece.

[0053] Please refer to FIG. 3 , which is a schematic structural diagram of the middle frame 200 of the electronic device 500 shown in FIG. 2 .

[0054] 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 connected, together forming 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 achieve a rotational connection between the first middle frame 100 and the second middle frame 110. When the first middle frame 100 rotates, the rotating shaft 540 drives the second middle frame 110 to rotate, thereby achieving the folding or unfolding of the electronic device 500.

[0055] The display screen 400 includes a first portion 410, a second portion 420, and a foldable portion 430. The foldable portion 430 is located between the first portion 410 and the second portion 420, and the foldable portion 430 can be bent along the Y direction. The first portion 410, the second portion 420, and the foldable portion 430 together constitute the display screen 400. In this embodiment, the display screen 400 is a flexible display screen 400. The display screen 400 is mounted on the middle frame 200 and fixedly connected to the middle frame 200. The first portion 410 is mounted on the first middle frame 100, the second portion 420 is mounted on the second middle frame 110, and the foldable portion 430 is arranged opposite to the rotating shaft 540. When the first middle frame 100 and the second middle frame 110 rotate relative to each other through the rotating shaft 540, the first portion 410 and the second portion 420 of the display screen 400 are driven to rotate relative to each other, and the foldable portion 430 is bent.

[0056] The back cover 300 is mounted on the side of the middle frame 200 facing away from the display screen 400. The first back cover 310 is mounted on the first middle frame 100 and fixedly connected to the first middle frame 100, and the second back cover 320 is mounted on the second middle frame 110 and fixedly connected to the second middle frame 110.

[0057] The first middle frame 100 and the second middle frame 110 rotate relative to each other via the hinge 540. As the first and second middle frames 100 and 110 rotate toward each other, they drive the first and second back covers 310 and 320 to rotate toward each other, and in turn, the display screen 400 folds, placing the electronic device 500 in a folded state. When the electronic device 500 is in the folded state, the foldable portion 430 of the display screen 400 bends, with the first portion 410 and the second portion 420 positioned relative to each other. At this point, the display screen 400 is positioned between the first and second middle frames 100 and 110, significantly reducing the risk of damage to the display screen 400 and effectively protecting it.

[0058] When the first middle frame 100 and the second middle frame 110 rotate away from each other, they drive the first back cover 310 and the second back cover 320 to rotate away from each other, and the display screen 400 to unfold, placing the electronic device 500 in the unfolded state. When the electronic device 500 is in the unfolded state, the foldable portion 430 unfolds, and the first portion 410 and the second portion 420 unfold relative to each other. At this point, the display surface of the display screen 400 is generally flat, with a large display area, thus achieving a large-screen display for the electronic device 500 and improving the user experience.

[0059] In one embodiment, the electronic device 500 further includes a second display screen. A single back cover 300 is provided. The back cover 300 is mounted on and fixedly connected to the first middle frame 100, and the second display screen is mounted on and fixedly connected to the second middle frame 110.

It should be noted that the first side portion 24, the second side portion 25, the third side portion 26 and the fourth side portion 27 are edge portions of the middle plate 20.

[0063] Please refer to FIG. 7 , which is an enlarged structural diagram of the frame 10 in area A shown in FIG. 6 .

[0064] The first mounting frame 30 includes a main body 31 and a rib 32. The main 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 main 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. The first side wall 332 may also have a smaller angle with the YZ plane, for example, 5 degrees or 10 degrees. In this embodiment, the first side wall 332 is perpendicular 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.

[0065] There are multiple groups of ribs 32. Multiple groups of ribs 32 are protruding from the first sidewall 332 and are spaced apart along the Y direction on the first sidewall 332. Each group of ribs 32 includes a first rib 34 and a second rib 35. The first 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 the surface of the first rib 34 away from the first sidewall 332. The first side surface 343 and the second side surface 344 are disposed opposite each other and are located on opposite sides of the Y direction. The third side surface 345 and the fourth side surface 346 are disposed opposite each other and are 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 sidewall 332.

[0066] The first rib 34 is provided with a first retaining groove 36. The first retaining groove 36 includes a first sub-retaining groove 361 and a second sub-retaining groove 362. From the first surface 341 to the first sidewall 332, the first side surface 343 is recessed inwardly toward the first rib 34, forming the first sub-retaining groove 361 between the first sidewall 332 and the first sidewall 332. From the first surface 341 to the first sidewall 332, the second side surface 344 is recessed inwardly toward the first rib 34, forming the second sub-retaining groove 362 between the first sidewall 332 and the first sidewall 332. It will be appreciated that the edge of the first rib 34 near the first side surface 343 serves as the wall of the first sub-retaining groove 361, while the edge of the first rib 34 near the second side surface 344 serves as the wall of the second sub-retaining groove 362. Both the wall of the first sub-retaining groove 361 and the wall of the second sub-retaining groove 362 face the first sidewall 332.

[0067] 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.

[0083] Please refer to FIG. 4 and FIG. 10 . FIG. 10 is a schematic diagram of a partial cross-sectional structure of the first middle frame 100 shown in FIG. 4 along the CC direction.

[0084] The rubber cover 40 is formed on the frame 10, the first frame 41, the second frame 42, and the third frame 43 are all formed on the middle plate 20, and the second mounting frame 50 is formed on the first mounting frame 30.

[0085] The second mounting frame 50 is formed in the first mounting groove 33 of the first mounting frame 30.

One protrusion 59 is located in one glue pulling groove 38 and is clamped and connected to the glue pulling groove 38. The first rib 34 is arranged in a one-to-one correspondence with the first groove 53, and one first rib 34 is located in one first groove 53.

The clamping protrusions 503 are arranged in a one-to-one correspondence with the clamping slots 39. One clamping protrusion 503 is located in one first clamping slot 39 and is clamped with the corresponding first clamping slot 39.

[0086] It is understood that after the encapsulation 40 is formed on the frame 10, the outer side surfaces of the first frame 41, the outer side surfaces of the second frame 42, and the outer side surfaces of the third frame 43 are exposed from the side of the electronic device 500, and thus constitute the frame of the electronic device 500. The second mounting groove 501 is the first receiving groove 101 of the electronic device 500 and is used to mount the rotating shaft 540 of the electronic device 500.

[0087] It should be noted that the rubber coating 40 is formed on the frame 10 by injection molding. The above-mentioned connection relationships are all directly formed during the injection molding. The specific processing method is described in detail below.

[0088] The middle frame 200 in this embodiment is composed of a metal frame 10 and a plastic coating 40. Compared with a pure metal middle frame 200, the middle frame 200 in this embodiment is lighter and can reduce weight, which is conducive to achieving lightweight electronic equipment 500 and improving user experience. For example, compared with an aluminum profile 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 outer surface of the metal frame 10 with the coating 40, the frame 10 can be protected, preventing the middle frame 200 from being corroded by salt spray and the like, thereby improving the corrosion resistance of the middle frame 200, allowing the electronic device 500 to be used stably without failure in a corrosive environment, thereby improving the durability of the electronic device 500.

[0089] While maintaining the protective effect and structural strength of the shaft area of ​​the middle frame 200, the middle frame 200 provided in this embodiment requires less space. 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 protective effect and structural strength of the shaft area can be achieved, thereby achieving a lighter and thinner electronic device 500. It should be noted that the "shaft area" referred to here is the area where the rotating shaft 540 is installed, that is, the area where the first mounting frame 30 and the second mounting frame 50 are located.

[0090] In this embodiment, by setting the first limiting groove 36, the second limiting groove 37 and the glue pulling groove 38 in the first mounting frame 30, when the glue bag 40 is formed on the surface of the frame body 10, the first clamping portion 55 is correspondingly formed in the first limiting groove 36, and the first limiting groove 36 and the first clamping portion 55 are clamped and connected in the direction perpendicular to the first side wall 332 (X direction), the second limiting groove 37 is correspondingly formed in the second clamping portion 58, the second limiting groove 37 and the second clamping portion 58 are clamped and connected in the X direction, the glue pulling groove 38 is correspondingly formed with a protrusion 59, and the glue pulling The groove 38 and the protrusion 59 are connected in a clamping manner 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, thereby preventing the rubber bag 40 from separating from the frame 10 in the X direction. The rubber pulling groove 38 limits the rubber bag 40 in the Z direction, thereby preventing the rubber bag 40 from separating from the frame 10 in the Z direction. This improves the stability of the connection between the rubber bag 40 and the frame 10, prevents the rubber bag 40 from separating from the frame 10 in the axial area, and realizes a 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 separate from the frame 10 when an action is applied to the rubber bag 40.

[0091] Among them, by providing the first rib 34 and the first limiting groove 36 on 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 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 separating 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 the 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.

[0092] Furthermore, by providing a second rib 35 and a second limiting groove 37 on the first mounting frame 30, when the rubber bag 40 is formed on the surface of the frame body 10, a second groove 56 is correspondingly formed on the outer surface of the second rib, and a second clamping portion 58 is correspondingly formed in the second limiting groove 37. Thus, 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.

[0093] In this embodiment, by providing the adhesive drawing groove 38 in the frame 10, when the adhesive bag 40 is formed on the surface of the frame 10, a corresponding protrusion 59 is formed in the adhesive drawing groove 38. Therefore, when a force is applied to the adhesive bag 40 along the Z direction, the abutting wall of the adhesive drawing groove 38 abuts against the protrusion 59, and the abutting wall acts as a limiter for the adhesive bag 40, thereby preventing the adhesive bag 40 from separating from the frame 10 along the Z direction. For example, when a force is applied to the adhesive bag 40 along the negative direction of the Z axis, the protrusion 59 abuts against the first abutting wall 381, which acts as a limiter for the protrusion 59, thereby preventing the adhesive bag 40 from separating from the frame 10 along the negative direction of the Z axis. When a force is applied to the adhesive bag 40 along the positive direction of the Z axis, the protrusion 59 abuts against the second abutting wall 382, ​​which acts as a limiter for the protrusion 59, thereby preventing the adhesive bag 40 from separating from the frame 10 along the positive direction of the Z axis.

[0094] 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.

[0095] 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.

[0096] Please refer to FIG. 11 , which is a flowchart of manufacturing the first middle frame 100 shown in FIG. 4 .

[0097] The manufacturing process of the first middle frame 100 includes:

[0098] S1: Provide a basic frame, the basic frame including a first installation frame, the first installation frame is provided with a first installation groove, the first installation groove includes a first side wall, the first side wall is provided with a basic rib, and the side of the basic rib is provided with a limiting groove.

[0100] S3: Injection molding is performed on the outer surface of the frame body 10 to form a rubber coating 40 , thereby obtaining the first middle frame 100 .

[0101] In S1, the base frame is manufactured by die-casting. The base frame is made of a material such as a magnesium alloy, an aluminum alloy, a titanium alloy, or stainless steel. Multiple base ribs are provided, spaced apart along the length of the first side wall. The base frame also includes a middle plate fixedly connected to one side of the first mounting frame.

[0102] It should be noted that the basic rib and retaining groove are formed directly in the mold during die-casting of the basic frame. The basic rib includes two side surfaces extending along the length of the first side wall. These two side surfaces are recessed into the rib 32 and form retaining grooves between them and the first side wall. In this embodiment, the retaining groove walls are curved. In other embodiments, the retaining groove walls may also be inclined.

[0103] In S2, a CNC (numerically controlled) machine tool cuts the surface of the base rib to form a glue groove 38. After cutting, the base rib is divided into two parts, namely a first rib 34 and a second rib 35, thereby forming the frame 10. The first rib 34 and the second rib 35 are arranged side by side and spaced apart along the width direction of the first side wall. A first limiting groove 36 is formed between the side surface of the first rib 34 and the first side wall, and a second limiting groove 37 is formed between the side surface of the second rib 35 and the first side wall.

[0104] In S3, the material of the overmolding 40 is plastic. During the injection molding process, the frame 10 is first placed in a mold, and then liquid plastic material is injected into the mold. The plastic material is then pressurized to coat the surface of the frame 10. The plastic is then cooled to form the overmolding 40. In this embodiment, the overmolding 40 coats the surface of the first mounting frame 30 and the side edges of the midplane 20.

[0106] In this embodiment, by injection molding the overmolding 40 on the surface of the frame 10, the mass of the middle frame 200 can be reduced, thereby achieving a lightweight electronic device 500 and improving the user experience. Furthermore, by injection molding the overmolding 40 on the surface of the frame 10, the frame 10 is protected from corrosion by salt spray and other factors, thereby improving the corrosion resistance of the middle frame 200. This allows the electronic device 500 to operate stably without failure in corrosive environments, thereby enhancing the durability of the electronic device 500.

[0107] At the same time, in this embodiment, by providing the first limiting groove 36 and the second limiting groove 37 in the frame 10, when the rubber bag 40 is formed on the surface of the frame 10, a first clamping portion 55 is correspondingly formed in the first limiting groove 36, and a second clamping portion 58 is correspondingly formed in the second limiting groove 37, so that the first limiting groove 36 has a limiting effect on the first clamping portion 55, and the second limiting groove 37 has a limiting effect on the second clamping portion 58, thereby preventing the rubber bag 40 from detaching from the frame 10 when a force is applied to the rubber bag 40 in a direction perpendicular to the first side wall (X direction). Furthermore, by providing a glue pulling groove 38 in the frame 10, when the glue bag 40 is formed on the surface of the frame 10, a corresponding protrusion 59 is formed in the glue pulling groove 38, so that the glue pulling groove 38 acts as a limiter for the protrusion 59, thereby preventing the glue bag 40 from being separated from the frame 10 when a force is applied to the glue bag 40 along the width direction of the first side wall (Z direction), thereby improving the stability of the connection between the glue bag 40 and the frame 10, and preventing the glue bag 40 from being separated from the frame 10 in the axial area.
