Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically, to a foldable electronic device and a protective component. Background Technology

[0002] With the development of electronic device technology, foldable electronic devices are gradually gaining popularity among users. For inward-folding foldable electronic devices, the screen may bend in a teardrop shape when folded, creating a gap in the hinge area. Dust particles or liquids from the external environment can enter through this gap and damage the screen. Therefore, improving the reliability of the screen in the hinge area of ​​foldable electronic devices is an urgent problem to be solved. Summary of the Invention

[0003] This application provides a foldable electronic device and a protective component. The protective component of the foldable electronic device can always be in contact with the screen module in the hinge assembly area to prevent foreign objects from entering from the hinge assembly area and damaging the screen module.

[0004] In a first aspect, a foldable electronic device is provided, comprising: a first mid-frame and a second mid-frame; a hinge assembly rotatably connected to the first mid-frame and the second mid-frame respectively; a screen module fixed to the first mid-frame and the second mid-frame, the screen module including a first display portion corresponding to the first mid-frame, a second display portion corresponding to the second mid-frame, and a foldable display portion corresponding to the hinge assembly, the foldable display portion being located between the first display portion and the second display portion; and a protective assembly disposed between the first mid-frame and the second mid-frame and connected to the hinge assembly; wherein the protective assembly includes: an elastic member, the elastic member including a first portion away from the foldable display portion, a second portion conforming to the surface of the foldable display portion, and a connecting rib disposed between the first portion and the second portion, the connecting rib being connected to the first portion and the second portion respectively.

[0005] In conjunction with the first aspect, in some implementations of the first aspect, when the foldable electronic device is in an unfolded state, the first part and the second part extend along a first direction, the second part is attached to the surface of the foldable display section along a second direction, and the second direction is perpendicular to the first direction and perpendicular to the axial direction of the pivot assembly.

[0006] Based on the above technical solution, the elastic element can fit against the surface of the foldable display section, preventing external dust particles or liquids from entering the hinge assembly area from the foldable display section, thus avoiding damage to the screen module and improving the reliability of the screen module.

[0007] In conjunction with the first aspect, in some implementations of the first aspect, the projection of the first end point of the connecting rib in the second direction does not overlap with the second end point of the connecting rib.

[0008] Based on the above technical solution, the connecting rib will always be under force during the process of the elastic element changing from the unfolded state to the folded state. In the folded state, the connecting rib can press the second part against the surface of the foldable display part, so that the second part is always in close contact with the surface of the foldable display part, thereby improving the tightness of the fit between the elastic element and the foldable display part during the process of changing from the unfolded state to the foldable state.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the projection of the connecting rib in the axial direction of the rotating shaft assembly is linear.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the projection of the connecting rib in the axial direction of the rotating shaft assembly is bent.

[0011] Based on the above technical solution, when the foldable electronic device is in the unfolded state, the position of the foldable display part may be lower than the first display part and the second display part. Therefore, when the connecting rib is bent, the second part can be pressed on the surface of the lower foldable display part to improve the tightness of the fit between the elastic element and the foldable display part.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the protective component further includes an insert disposed on the side of the elastic member away from the screen module along the axial direction of the pivot assembly. The insert includes a main body portion and a protrusion portion protruding from the main body portion. The protrusion portion protrudes toward the elastic member along the axial direction of the pivot assembly. The surface of the first portion facing the insert is provided with a mounting hole corresponding to the protrusion portion, and the protrusion portion is fixed in the mounting hole.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the elastic element is formed on the insert by an insert molding process.

[0014] Based on the above technical solution, the elastic component is directly formed on the insert, which improves the tightness of the fit between the elastic component and the insert and avoids the cumbersome process of reassembling the two components when they are formed separately.

[0015] Based on the above technical solution, since the protrusion of the embedded part is embedded in the mounting hole of the elastic part, when the user uses the foldable electronic device, the elastic part can be seen from the surface of the screen module but the embedded part cannot be seen, which helps to improve the aesthetics of the foldable electronic device.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the protective component further includes a positioning member disposed on the side of the insert away from the screen module along the axial direction of the pivot assembly, the positioning member having a recessed portion on its surface facing the insert, the insert being partially disposed in the recessed portion; the positioning member is fixedly connected to the pivot assembly so that the protective component is fixed in the foldable electronic device.

[0017] Based on the above technical solution, the positioning component can accommodate the insert, so that the entire protective assembly is fixedly connected to the pivot assembly, which is beneficial to the assembly of foldable electronic devices.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the positioning element and the rotating shaft assembly are fixedly connected by dispensing adhesive.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the positioning element is manufactured by a metal injection molding process.

[0020] Based on the above technical solution, metal injection molding can more easily produce positioning parts with complex geometries, thereby improving the yield of positioning parts.

[0021] In conjunction with the first aspect, in some implementations of the first aspect, in the axial direction of the rotating shaft assembly, the depth of the recess is greater than or equal to the thickness of the main body, so that the main body is embedded in the recess.

[0022] Based on the above technical solution, after the embedded part is installed into the positioning part, it will not increase the thickness of the protective component, which is beneficial to the thin and light design of foldable electronic devices.

[0023] In conjunction with the first aspect, in some implementations of the first aspect, the bottom wall of the recess is welded to the surface of the main body facing the positioning member.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, the recess includes a through hole, the main body is embedded in the through hole, and the main body is welded to the inner wall of the through hole.

[0025] Based on the above technical solution, welding connection makes the connection between the insert and the positioning part more reliable, thereby improving the reliability of the protective component.

[0026] In conjunction with the first aspect, in some implementations of the first aspect, the projection of the insert in the axial direction of the shaft assembly overlaps with the projection of the through hole.

[0027] Based on the above technical solution, the fit between the through holes of the insert and the positioning part is higher, which is beneficial to the welding connection effect and improves the fixing reliability between the insert and the positioning part.

[0028] In conjunction with the first aspect, in some implementations of the first aspect, the elastic member further includes a third portion extending from the first portion toward the first direction, the third portion being provided with a first extension portion that contacts the surface of the screen module; wherein, the foldable electronic device further includes a first side frame, the first side frame being disposed around the outer periphery of the first mid-frame, the first side frame including a first pressing portion, the first pressing portion being disposed above the first extension portion to press the first extension portion onto the surface of the screen module.

[0029] Based on the above technical solution, the elastic element can be more securely installed in the foldable electronic device by cooperating with the first side frame and the first extension, thereby improving the tightness of the elastic element when installed in the foldable electronic device.

[0030] In conjunction with the first aspect, in some implementations of the first aspect, the third part further includes a second extension extending from the first extension toward the second direction; the first side frame further includes a second pressing portion disposed above the second extension to press the second extension onto the screen module.

[0031] Based on the above technical solution, the elastic element can be more securely installed in the foldable electronic device by cooperating with the second side frame and the second extension, thereby further improving the tightness of the elastic element when installed in the foldable electronic device.

[0032] In conjunction with the first aspect, in some implementations of the first aspect, the first middle frame includes a protrusion that protrudes toward the elastic member along the second direction, and the third part is provided with a receiving portion at a position corresponding to the protrusion, wherein the protrusion is received in the receiving portion.

[0033] Based on the above technical solution, the elastic element is further positioned in the first middle frame by the protrusion, which helps to improve the convenience of installing the protective component in foldable electronic devices.

[0034] In conjunction with the first aspect, in some implementations of the first aspect, the first middle frame includes a protrusion block fixedly connected to the first middle frame, the protrusion block protruding toward the elastic member along the second direction, the hardness of the protrusion block being greater than the hardness of the first middle frame, and the third part having a receiving portion at a position corresponding to the protrusion block, the protrusion block being received in the receiving portion.

[0035] Based on the above technical solution, by setting up protrusions with higher hardness, the impact resistance of the protrusions can be improved, preventing misalignment of elastic components in foldable electronic devices and improving the reliability of protective components.

[0036] In a second aspect, a protective component is provided for protecting a foldable display portion in a screen module corresponding to a hinge assembly of a foldable electronic device between a first mid-frame and a second mid-frame. The protective component is disposed between the first mid-frame and the second mid-frame and connected to the hinge assembly. The protective component includes an elastic member comprising a first portion away from the foldable display portion, a second portion abutting against the surface of the foldable display portion, and a connecting rib disposed between the first portion and the second portion, the connecting rib being connected to the first portion and the second portion respectively.

[0037] In some possible implementations, the foldable electronic device includes: a first mid-frame and a second mid-frame; a hinge assembly rotatably connected to the first mid-frame and the second mid-frame respectively; and a screen module fixed to the first mid-frame and the second mid-frame, the screen module including a first display portion corresponding to the first mid-frame, a second display portion corresponding to the second mid-frame, and a foldable display portion corresponding to the hinge assembly, the foldable display portion being located between the first display portion and the second display portion.

[0038] In conjunction with the second aspect, in some implementations of the second aspect, when the foldable electronic device is in an unfolded state, the first part and the second part extend along a first direction, the second part is attached to the surface of the foldable display section along a second direction, and the second direction is perpendicular to the first direction and perpendicular to the axial direction of the pivot assembly.

[0039] Based on the above technical solution, the elastic element can fit against the surface of the foldable display section, preventing external dust particles or liquids from entering the hinge assembly area from the foldable display section, thus avoiding damage to the screen module and improving the reliability of the screen module.

[0040] In conjunction with the second aspect, in some implementations of the second aspect, the projection of the first endpoint of the connecting rib in the second direction does not overlap with the second endpoint of the connecting rib.

[0041] Based on the above technical solution, the connecting rib will always be under force during the process of the elastic element changing from the unfolded state to the folded state. In the folded state, the connecting rib can press the second part against the surface of the foldable display part, so that the second part is always in close contact with the surface of the foldable display part, thereby improving the tightness of the fit between the elastic element and the foldable display part during the process of changing from the unfolded state to the foldable state.

[0042] In conjunction with the second aspect, in some implementations of the second aspect, the projection of the connecting rib in the axial direction of the rotating shaft assembly is linear.

[0043] In conjunction with the second aspect, in some implementations of the second aspect, the projection of the connecting rib in the axial direction of the rotating shaft assembly is bent.

[0044] Based on the above technical solution, when the foldable electronic device is in the unfolded state, the position of the foldable display part may be lower than the first display part and the second display part. Therefore, when the connecting rib is bent, the second part can be pressed on the surface of the lower foldable display part to improve the tightness of the fit between the elastic element and the foldable display part.

[0045] In conjunction with the second aspect, in some implementations of the second aspect, the protective component further includes an insert disposed on the side of the elastic member away from the screen module along the axial direction of the pivot assembly. The insert includes a main body portion and a protrusion portion protruding from the main body portion, the protrusion portion protruding toward the elastic member along the axial direction of the pivot assembly. The surface of the first portion facing the insert is provided with a mounting hole corresponding to the protrusion portion, and the protrusion portion is fixed in the mounting hole.

[0046] In conjunction with the second aspect, in some implementations of the second aspect, the elastic element is formed on the insert by an insert molding process.

[0047] Based on the above technical solution, the elastic component is directly formed on the insert, which improves the tightness of the fit between the elastic component and the insert and avoids the cumbersome process of reassembling the two components when they are formed separately.

[0048] Based on the above technical solution, since the protrusion of the embedded part is embedded in the mounting hole of the elastic part, when the user uses the foldable electronic device, the elastic part can be seen from the surface of the screen module but the embedded part cannot be seen, which helps to improve the aesthetics of the foldable electronic device.

[0049] In conjunction with the second aspect, in some implementations of the second aspect, the protective component further includes a positioning member disposed on the side of the insert away from the screen module along the axial direction of the pivot assembly. The positioning member has a recess on its surface facing the insert, and the insert is partially disposed in the recess. The positioning member is fixedly connected to the pivot assembly so that the protective component is fixed in the foldable electronic device.

[0050] Based on the above technical solution, the positioning component can accommodate the insert, so that the entire protective assembly is fixedly connected to the pivot assembly, which is beneficial to the assembly of foldable electronic devices.

[0051] In conjunction with the second aspect, in some implementations of the second aspect, the positioning element and the rotating shaft assembly are fixedly connected by dispensing adhesive.

[0052] In conjunction with the second aspect, in some implementations of the second aspect, the positioning element is manufactured by a metal injection molding process.

[0053] Based on the above technical solution, metal injection molding can more easily produce positioning parts with complex geometries, thereby improving the yield of positioning parts.

[0054] In conjunction with the second aspect, in some implementations of the second aspect, in the axial direction of the rotating shaft assembly, the depth of the recess is greater than or equal to the thickness of the main body, so that the main body is embedded in the recess.

[0055] Based on the above technical solution, after the embedded part is installed into the positioning part, it will not increase the thickness of the protective component, which is beneficial to the thin and light design of foldable electronic devices.

[0101] Metal injection molding (MIM) is a metal processing technology. Its basic process is as follows: First, solid powder is uniformly mixed with organic binder, granulated, and then injected into the mold cavity by injection molding machine under heating and plasticizing conditions to solidify and form the product. Then, the binder in the preform is removed by chemical or thermal decomposition methods. Finally, the product is sintered and densified to obtain the final product.

[0102] Insert molding process refers to an injection molding process, also known as metal insert injection molding process. Its basic process is as follows: the metal insert is pre-fixed in an appropriate position in the mold, and then plastic is injected for molding. After the mold is opened, the insert is tightly encased in the product by the cooled and solidified plastic to obtain a product with inserts such as threaded holes and electrodes.

[0103] Dispensing refers to a packaging process, also known as gluing, coating, potting, or dripping. The basic process involves applying, potting, or dripping electronic adhesives, oils, or other liquids onto a product to achieve functions such as adhesion, encapsulation, insulation, fixation, or surface smoothing.

The space between the second display unit 42 and the second middle frame 20 can be used to arrange components of the foldable electronic device 1, such as antennas, circuit board assemblies, etc.

[0115] The first housing 100 and the second housing 200 are rotatable relative to each other about the folding axis of the foldable electronic device 1. For example, the first housing 100 may be rotatable relative to the second housing 200 about the folding axis, and / or the second housing 200 may be rotatable relative to the first housing 100 about the folding axis, which may allow the foldable electronic device 1 to switch between a folded state and an unfolded state.

[0116] In one embodiment of this application, the middle frame and the side frame can be two parts of the housing of the foldable electronic device 1. The middle frame and the side frame can be connected, and the connection method does not have to be an assembly method such as snap-fit, adhesive, welding, riveting, or clearance fit. The connection between the middle frame and the side frame is usually difficult to separate. In another embodiment of this application, the middle frame and the side frame can be two different components. In yet another embodiment of this application, the middle frame and the side frame can be a single component, which can be manufactured using a one-piece molding process. By assembling the middle frame and the side frame together, the housing of the foldable electronic device 1 can be formed.

[0117] The hinge assembly 30 can be connected between the first housing 100 and the second housing 200. The foldable display portion 43 of the screen module 40 can abut against the surface of the hinge assembly 30. When the foldable electronic device 1 is in the unfolded state, the foldable display portion 43 of the screen module 40 and the hinge assembly 30 are stacked. Under the action of the hinge assembly 30, the first housing 100 and the second housing 200 can move closer to each other or further away from each other. Correspondingly, the first display portion 41 and the second display portion 42 of the screen module 40 can move closer to each other or further away from each other, so that the screen module 40 can be folded or unfolded, that is, the foldable electronic device 1 is in a folded state or an unfolded state.

[0118] In the foldable electronic device 1, the number of hinge assemblies 30 can be one or more. Figure 1 The number of examples shown may be two, three, or more, but the embodiments of this application do not limit this.

[0119] In this application, when the foldable electronic device 1 is in the unfolded state (flattened state), the angle between the first housing 100 and the second housing 200 can be approximately 180°. The foldable electronic device 1 being in the folded state means that the foldable electronic device 1 is currently bent, and the degree of bending of the foldable electronic device 1 reaches its maximum. At this time, the first housing 100 and the second housing 200 can be arranged parallel to each other, spaced apart from each other, and facing each other, with the spacing between the first housing 100 and the second housing 200 being minimal. At least a portion of the first housing 100 and the second housing 200 are housed within the space enclosed by the screen module 40; the first display unit 41, the first housing 100, the second housing 200, and the second display unit 42 are sequentially stacked. Similarly, the first display unit 41 and the second display unit 42 can be arranged parallel to each other, spaced apart from each other, and facing each other (the spacing between the first middle frame 10 and the second middle frame 20 is less than the spacing between the first display unit 41 and the second display unit 42). At this time, the first display unit 41 and the second display unit 42 can be considered to be located on different planes.

[0120] The foldable electronic device 1 in a folded state can include an inward folded state. When the foldable electronic device 1 is in the inward folded state, the first mid-frame 10 and the second mid-frame 20 can be close to each other, and the first display unit 41 and the second display unit 42 can be close to each other. The first mid-frame 10, the second mid-frame 20, and the hinge assembly 30 can form a screen-accommodating area for accommodating the screen module 40. That is, the screen module 40 can be housed within the space between the first mid-frame 10 and the second mid-frame 20.

[0121] Combination Figure 1 as well as Figure 2 The composition of the foldable electronic device 1 provided in the embodiments of this application is further explained.

[0122] like Figure 2 (a) and Figure 2 As shown in (b), the foldable electronic device 1 includes components such as a first housing 100, a second housing 200, a hinge assembly 30, a screen module 40, and a protective assembly 50. The hinge assembly 30 includes components such as a main shaft 31, a door panel 32, an arc arm 33, and a housing support 34. The first housing support 341 can be fixed to the first housing 100, for example, to the first middle frame 10. The second housing support 342 can be fixed to the second housing 200, for example, to the second middle frame 20. The first housing support 341 and the second housing support 342 can rotate relative to the main shaft 31. Through the rotational movement of the first housing 100 and the second housing 200, the rotational movement of the first housing support 341 and the second housing support 342 can be driven, realizing the conversion between the unfolded state and the folded state of the foldable electronic device 1.

[0123] Still Figure 2 As shown in (a), on one side of the foldable electronic device 1 along the y-direction, the foldable electronic device 1 is provided with a first side frame 60, a protective component 50, a screen module 40, and a first middle frame 10 stacked along the z-direction; correspondingly, on the other side of the foldable electronic device 1 along the y-direction, the foldable electronic device 1 is provided with a second side frame 70, a protective component 50, a screen module 40, and a second middle frame 20 stacked along the z-direction; for ease of explanation, in the following embodiments, the first middle frame 10 and the first side frame 60 are used as examples for explanation, and the relevant settings of the second middle frame 20 and the second side frame 70 can also refer to the settings of the first middle frame 10 and the first side frame 60. A part of the protective component 50 is disposed between the first side frame 60 and the screen module 40, and a part of the protective component 50 contacts, adheres to, or abuts against the screen module 40.

[0124] like Figure 2 As shown in (b), the door panel 32 is fixed on the arc arm 33. One end of the arc arm 33 is accommodated in the main shaft part 31 and is rotatably connected to the main shaft part 31. The other end of the arc arm 33 is accommodated in one end of the housing bracket 34 and is rotatably connected to the housing bracket 34. The other end of the housing bracket 34 is fixedly connected to the middle frame. The screen module 40 is fixedly connected to the two middle frames. Taking the first middle frame 10 and the first housing bracket 341 as an example, one end of the arc arm 33 is accommodated in the main shaft part 31 and is rotatably connected to the main shaft part 31. The other end of the arc arm 33 is accommodated in one end of the first housing bracket 341 and is rotatably connected to the first housing bracket 341. The other end of the first housing bracket 341 is fixedly connected to the first middle frame 10. The protective component 50 is connected to the main shaft part 31 in the thickness direction of the foldable electronic device 1.

[0125] With the development of electronic device technology, foldable electronic devices are gradually becoming popular among users. Figure 3 This is a schematic diagram of the combination of an elastic element and a screen module in a foldable electronic device. Figure 2 as well as Figure 3 To further explain, for foldable electronic devices that fold inwards, when the device is folded, the foldable display section 43 of the screen module 40 will bend in a teardrop shape. The elastic element 51 is not in contact with the foldable display section 43 when folded, therefore, a gap exists between the elastic element 51 and the foldable display section 43. Dust particles or liquids from the external environment can enter the foldable electronic device through this gap. For example, they may enter the area between the foldable display section 43 and the hinge assembly 30, causing damage to the flexible screen within the foldable display section 43 area. Therefore, how to reduce the potential external damage to the foldable display section 43 of the screen module 40 of the foldable electronic device is an urgent problem to be solved.

[0126] To address the aforementioned issues, this application provides a foldable electronic device. Through a protective component, the protective component and the screen module are tightly fitted together in the folded state to prevent foreign objects from entering the area between the foldable display and the hinge assembly and damaging the foldable display.

[0127] Figure 4 This is a schematic diagram of a protective component provided in an embodiment of this application. Figure 5 yes Figure 4 A schematic exploded view of the protective components shown.

[0128] Combination Figure 4 as well as Figure 5 The composition of the protective component 50 provided in this application embodiment is further described below. The protective component 50 includes an elastic member 51, an insert member 52, and a positioning member 53. The various components of the protective component 50 are described below.

[0129] It should be noted that since the elastic element 51 is elastic and can undergo elastic deformation, when the foldable electronic device 1 is in the unfolded state, the folded state, and the process of transitioning between the unfolded state and the folded state, the elastic element 51 will undergo elastic deformation after being subjected to force, and there will be different states. Therefore, it can also be considered that the elastic element 51 has an unfolded state, a folded state, and a state during the transition between the unfolded state and the folded state.

[0130] like Figure 4 and Figure 5 As shown, the elastic member 51 is in the unfolded state. The elastic member 51 includes a first part 511, a second part 512 and a third part 513, wherein the first part 511 can be called the appearance part, the second part 512 can be called the dustproof part and the third part 513 can be called the mounting part.

[0131] The first portion 511 of the elastic member 51 moves away from the first surface of the screen module 40 in the z direction. The first surface can refer to the surface of the screen module 40 that displays the image. That is, the surface of the first display unit 41 that displays the image, the surface of the second display unit 42 that displays the image, and the surface of the foldable display unit that displays the image can all be called the first surface. The first surface is used to indicate one side of the screen module 40 that displays the image. The second portion 512 of the elastic member 51 moves close to the first surface in the z direction and is in contact with the first surface. The third portion 513 of the elastic member 51 can be regarded as the portion of the first portion 511 that extends in the y direction. The side of the third portion 513 facing the first surface in the z direction is in contact with the first surface. The side of the third portion 513 away from the first surface in the z direction is in contact with the first side frame 60.

[0132] The three parts of the elastic element 51 can be made of the same material. For example, the elastic element 51 can be a soft rubber, which can include one or more of the following: silicone, rubber, thermoplastic elastomer, thermoplastic polyurethane elastomer rubber, or soft PVC.

[0133] When the elastic element 51 is in the unfolded state, the first part 511 can be a protruding part with an arc shape, and the protruding direction of the protruding part is away from the surface of the screen module 40 displaying the image.

[0134] When the elastic member 51 is in the unfolded state, the first part 511 and the second part 512 may both extend along the first direction, and the second part 512 abuts against the surface of the foldable display part 43 along the second direction. The second part 512 may be a part that is parallel to the plane where the screen module 40 is located and directly contacts or abuts against the screen module 40.

[0135] The first part 511 and the second part 512 of the elastic member 51 are connected by a connecting rib 514.

[0136] The connecting rib 514 may include a first endpoint 5141 and a second endpoint 5142. The projection of the first endpoint 5141 in the second direction does not overlap with the second endpoint 5142. The first endpoint 5141 may be a point on the first part 511. Therefore, the first endpoint 5141 can be regarded as being on both the connecting rib 514 and the first part 511, and can also be referred to as the starting point of the connecting rib 514. Correspondingly, the second endpoint 5142 may be a point on the second part 512. Therefore, the second endpoint 5142 can be regarded as being on both the connecting rib 514 and the second part 512, and can also be referred to as the ending point of the connecting rib 514.

[0137] The projection of the first endpoint 5141 in the second direction does not overlap with the second endpoint 5142, indicating that the connecting rib 514 is at a certain angle to the second direction.

[0138] Figure 6 yes Figure 4 A schematic diagram of the elastic element in the protective assembly shown.

[0139] In some possible implementations, the projection of the connecting rib 514 onto the axial direction of the shaft assembly 30 is linear, such as... Figure 6 As shown, the connecting rib 514 is a straight connecting rib, which can be regarded as a connecting rib 514 formed by the direct connection of the first part 511 and the second part 512 through two endpoints in the axial direction of the rotating shaft assembly 30.

[0140] Still Figure 6As shown, the projection of the two straight connecting ribs 514 in the axial direction of the rotating shaft assembly 30 is a positive figure-eight shape. At this time, the first end point 5141 is close to the center of the elastic member 51, and the second end point 5142 is far away from the center of the elastic member 51.

[0141] In some possible implementations, the projection of the two straight connecting ribs 514 onto the axial direction of the rotating shaft assembly 30 can also be an inverted V-shape. In this case, the first end point 5141 is far from the center of the elastic member 51, and the second end point 5142 is close to the center of the elastic member 51.

[0142] Based on the above technical solution, during the process of the elastic member 51 changing from the unfolded state to the folded state, after the elastic member 51 is subjected to force, it will transmit the elastic force from the first end point 5141 to the second end point 5142 through the connecting rib 514, so that the second part 512 always remains in close contact with the foldable display part 43 during the process of the elastic member 51 changing from the unfolded state to the foldable state, and there will be no gap between the second part 512 and the foldable display part 43.

[0143] In some possible implementations, when the elastic element 51 is in a folded state, the connecting rib 514, under force, presses the second part 512 onto the surface of the foldable display part 43.

[0144] The elastic member 51 also includes a third part 513, which may be a portion of the first part 511 extending along a first direction. The third part 513 is provided with a first extension 5131 that abuts against the surface of the screen module 40.

[0145] The third part 513 of the elastic element 51 can be the part of the first part 511 that extends along the plane where the surface of the screen module 40 is located to the length direction of the screen module 40. The length direction of the screen module 40 can refer to the y direction or the first direction.

[0146] The first extension 5131 is in contact with the first surface on the side facing the first surface along the z direction, and the first extension 5131 is in contact with the first side frame 60 on the side away from the first surface along the z direction. It can also be said that the first extension 5131 is disposed between the first side frame 60 and the screen module 40.

[0147] The protective component 50 also includes an insert 52, which can also be called an insert steel sheet. The insert 52 is disposed on the side of the elastic member 51 away from the screen module 40 along the axial direction of the rotating shaft assembly 30. The insert 52 is provided with a main body 521 and a protrusion 522 protruding from the main body 521. The protrusion 522 protrudes along the axial direction of the rotating shaft assembly 30 on the side close to the elastic member 51.

[0148] The first part 511 of the elastic member 51 has a mounting hole 5111 on the surface of the side of the member 52 along the x direction. The mounting hole 5111 is recessed on the side of the member 52 away from the member 52 along the x direction. The mounting hole 5111 is used to connect with the member 52.

[0149] The protrusion 522 is accommodated in the mounting hole 5111 and is adapted to the mounting hole 5111. This adaptation includes matching in shape and size. The protrusion 522 of the insert 52 is disposed in the mounting hole 5111 of the first part 511 of the elastic member 51, connecting the insert 52 and the elastic member 51.

[0150] In some possible implementations, the elastic element 51 may be made of rubber or silicone, and the elastic element 51 may be formed on the insert 52 by an insert molding process, for example, it may be made by metal insert injection molding.

[0151] The elastic element 51 is made by metal insert injection molding, which means that the insert 52 is pre-fixed in the mold, and then rubber or silicone is injected to form the elastic element 51. After the mold is opened, the mounting hole 5111 of the first part 511 of the elastic element 51, which is cooled and solidified, tightly wraps the protrusion 522 of the insert 52, thereby directly obtaining an integral elastic element 51 and insert 52.

[0152] In some possible implementations, the elastic element 51 and the insert 52 can also be formed separately, and then the protrusion 522 of the insert is installed into the mounting hole 5111 of the elastic element 51, so that the elastic element 51 and the insert 52 are combined and connected.

[0153] Figure 7 yes Figure 4 A schematic exploded view of the protective components from another angle.

[0154] like Figure 7 As shown, the protective assembly 50 also includes a positioning member 53, which is disposed on the side of the insert 52 away from the screen module 40 along the axial direction of the pivot assembly 30. The surface of the positioning member 53 facing the insert 52 is provided with a recess 531, and the insert 52 is partially disposed in the recess 531. The positioning member 53 is connected to the main shaft to fix the protective assembly 50 in the foldable electronic device 1.

[0155] The cross-sectional shape of the positioning element 53 in a plane perpendicular to the folding axis is close to the shape of the letter "T". Therefore, the positioning element 53 can also be called a T-shaped block. The insert 52 and the positioning element 53 can be fixedly connected by welding.

[0156] The surface of the positioning member 53 facing the insert 52 is provided with a recess 531. The recess 531 is formed in a direction away from the insert 52. The insert 52 can be disposed in the recess 531. In other words, the insert 52 is embedded in the recess 531.

[0157] It should be noted that, in the axial direction of the rotating shaft assembly 30, the shape and size of the recess 531 are adapted to the shape and size of the insert 52. In other words, the projection of the insert 52 in the axial direction of the rotating shaft assembly 30 falls in the recess 531, or the projection of the insert 52 in the axial direction of the rotating shaft assembly 30 completely overlaps with the projection of the recess 531. That is to say, the insert 52 can be perfectly accommodated in the recess 531.

[0158] In some possible implementations, the size of the recess 531 is greater than or equal to the size of the insert 52 in the axial direction of the pivot assembly 30. In other words, the depth of the recess 531 is greater than or equal to the thickness of the main body 521. When the main body 521 is disposed in the recess 531, the insert 52 does not increase the thickness of the protective assembly 50.

[0159] The positioning component 53 can be manufactured using metal injection molding (MIM). This is because the positioning component 53 itself is small in size and also has a recess 531 for accommodating and fixing the insert 52. Therefore, the geometry of the positioning component 53 is relatively complex. The MIM process can manufacture metal parts with complex geometries, especially parts that are difficult to manufacture by traditional processing methods, including thin-walled structures and internal channels. This is beneficial to improving the yield of the positioning component 53.

[0160] Still referencing Figure 7 The welding connection between the insert 52 and the positioning member 53 means that the surface of the insert 52 facing the recess 531 can be welded to the bottom wall of the recess 531, or it can be connected by a dispensing process. For example, the bottom wall of the recess 531 can be welded to the surface of the main body 521 facing the positioning member 53, or it can be connected by a dispensing process.

[0161] The above describes the setting or installation method of a protective component 50 and its components provided by the embodiments of this application. The following describes other possible setting or installation methods of the protective component 50 and its components provided by the embodiments of this application.

[0162] Figure 8 This is a schematic diagram of another elastic element 51 provided in the embodiments of this application, and... Figure 6 The difference in the elastic element 51 shown is that the shape of the connecting rib 514 between the first part 511 and the second part 512 is different.

[0163] like Figure 8 As shown, the connecting rib 514 between the first end point 5141 and the second end point 5142 is a bent connecting rib. The projection of the connecting rib 514 in the axial direction of the rotating shaft assembly 30 is bent. In the axial direction of the rotating shaft assembly 30, it can be regarded as the connecting rib 514 extending from the first end point 5141 towards the second part 512, then bending at a certain angle and continuing to extend, connecting with the second end point 5142.

[0164] Alternatively, the connecting rib 514 between the first part 511 and the second part 512 can be connected in a reverse folding shape. The cross-sectional shape of the connecting rib in the plane perpendicular to the folding axis is approximately S-shaped. The reverse folding can mean that the connecting rib 514 can present a similar S-shaped shape. One end of the S-shaped connecting rib can be connected to the mounting hole 5111 of the first part 511, and the other end of the S-shaped connecting rib can be connected to the second part 512.

[0165] Figure 9 This is a schematic exploded view of another protective component provided in the embodiments of this application.

[0166] The following sections will introduce them separately. Figure 9 The protective components shown are Figure 4 The differences in the protective components shown.

[0167] and Figure 4 The difference in the protective components shown is that the recess 531 of the positioning member 53 is set as a through hole 531a. That is, the recess 531 is provided through in the axial direction of the rotating shaft assembly 30. The positioning member 53 has a through hole 531a on the surface facing the insert 52. The insert 52 can be set in the through hole 531a. In other words, the insert 52 is embedded in the through hole 531a.

[0168] In some possible implementations, the shape and size of the through hole 531a are adapted to the shape and size of the insert 52. In other words, the projection of the insert 52 in the axial direction of the rotating shaft assembly 30 completely overlaps with the through hole 531a, and the insert 52 can be completely accommodated in the through hole 531a.

[0169] It should be noted that if the projection of the insert 52 in the axial direction of the rotating shaft assembly 30 does not completely overlap with the through hole 531a, then the insert 52 cannot be installed in the through hole 531a, which leads to assembly difficulties.

[0170] In the axial direction of the pivot assembly 30, the size of the through hole 531a is greater than or equal to the size of the insert 52. In other words, the depth of the through hole 531a is greater than or equal to the thickness of the insert 52. The thickness of the insert 52 does not include the size of the protrusion 522 of the insert 52 in the x direction. When the insert 52 is disposed in the through hole 531a, the insert 52 will not increase the thickness of the protective assembly 50.

[0171] exist Figure 9 In the protective assembly shown, the welding positions between the insert 52 and the positioning member 53 are also different. Since the recess 531 is configured as a through hole 531a, when the insert 52 is installed in the through hole 531a, in the axial direction of the rotating shaft assembly 30, the through hole 531a has no wall in contact with the insert 52. The positioning member 53 can be regarded as being arranged around the insert 52. The outer periphery of the insert 52 is in contact with the inner wall of the through hole 531a, and the insert 52 is welded at the position where it contacts the inner wall of the through hole 531a.

[0172] Figure 10 yes Figure 9 The diagram shows the protective assembly installed in the spindle section.

[0173] like Figure 10 As shown in (a), the protective assembly 50 is installed into the spindle section 31 along the z-direction, as... Figure 10 As shown in (b), the protective assembly has been inserted into the spindle section 31. Figure 10 (c) in the middle is Figure 10 In the cross-sectional view along the z-direction (b) in the diagram, it can be seen that there is a gap between the positioning member 53 and the main spindle portion 31, and also a gap between the positioning member 53, the insert 52 and the main spindle portion 31. These gaps are filled by a dispensing process to achieve a fixed connection between the protective assembly 50 and the main spindle portion 31. Figure 10 As shown in (d), the first adhesive 515 fills the gap in the insertion groove of the positioning member 53 into the spindle portion 31, and the second adhesive 516 fills the gap formed by the positioning member 53, the insert 52 and the spindle portion 31.

[0174] It should be noted that the positioning member 53 in the protective component 50 serves two purposes: firstly, it fixes the embedded member 52 and the elastic member 51 in place; secondly, the positioning member 53 also connects the protective component 50 to the main shaft, thus fixing the protective component 50 in the foldable electronic device 1.

[0175] To further enhance the robustness of the protective components when installed in foldable electronic devices, the side frames can be used to further reinforce the protective components.

[0176] Figure 11This is a partially schematic exploded view of a foldable electronic device provided in an embodiment of this application. Figure 12 yes Figure 11 The exploded cross-sectional view shown. Figure 13 yes Figure 12 A magnified view of a portion of the image. Figure 14 yes Figure 1 The cross-sectional view of the foldable electronic device 1 shown is shown. Figure 15 yes Figure 14 A magnified view of a portion of the image. Figure 16 yes Figure 15 A schematic diagram of the cross-section.

[0177] refer to Figures 11 to 16 Taking the first middle frame 10 and the first side frame 60 as examples, the first side frame 60 includes a first pressing part 601 near the first surface. The side of the first pressing part 601 facing the first surface is in contact with the side of the first extension 5131 of the elastic member 51 away from the first surface. The side of the first extension 5131 of the elastic member 51 near the first surface is in contact with the first surface.

[0178] When the first side frame 60 is installed in the foldable electronic device 1, the first pressing part 601 presses the first extension 5131 of the elastic member 51 onto the first surface of the screen module 40. In other words, the first extension 5131 of the elastic member 51 is sandwiched between the first pressing part 601 and the screen module 40, so that the first extension 5131 fits more tightly onto the first surface of the screen module 40. Specifically, the first extension 5131 fits onto the surface of the first display part 41.

[0179] In some possible implementations, the third portion 513 of the elastic member 51 further includes a second extension 5132, which is a portion of the first extension 5131 extending along a second direction at the edge of the pivot assembly 30 away from the screen module 40 in the axial direction; the first side frame 60 further includes a second pressing portion 602, which is a portion of the first pressing portion 601 extending along a second direction at the edge of the pivot assembly 30 away from the screen module 40 in the axial direction, and the second pressing portion 602 contacts or abuts against the second extension 5132.

[0180] In the cross section along the y direction, the angle between the first extension 5131 and the second extension 5132 can be 90° or approximately perpendicular. In other words, the first extension 5131 and the second extension 5132 together enclose the screen module 40.

[0181] Similarly, in the cross section along the y direction, the angle between the first pressing part 601 and the second pressing part 602 can be 90° or approximately perpendicular. In other words, the first pressing part 601 and the second pressing part 602 together wrap the elastic member 51.

[0182] like Figure 16 As shown, in a cross section along the y direction, the foldable electronic device 1 can be viewed from the inside to the outside as a screen module 40, a third part 513 of the elastic element 51, and a first side frame 60, respectively.

[0183] Figure 17 yes Figure 1 The foldable electronic device 1 shown is a partial cross-sectional view along the x-direction.

[0184] like Figure 17 As shown, the foldable electronic device 1 is currently in the unfolded state. The third part 513 of the elastic member 51 is disposed on the first surface of the screen module 40. The second part of the elastic member is tightly attached to the surface of the screen module 40. The first side frame 60 is also mounted on the surface of the screen module 40, and the first side frame 60 presses the third part 513 of the elastic member 51 between the first side frame 60 and the screen module 40.

[0185] Based on the above technical solution, the second extension 5132 is disposed between the screen module 40 and the second pressing part 602 of the first side frame 60 to prevent the third part 513 of the elastic member 51 from detaching from the first side frame 60.

[0186] Figure 18 This is a schematic diagram of a foldable electronic device 1 provided in an embodiment of this application. Figure 19 yes Figure 18 A partial cross-sectional view of the foldable electronic device 1 shown.

[0187] like Figure 18 and Figure 19 As shown, the foldable electronic device 1 is currently in a folded state, and during the process of the foldable electronic device 1 transitioning from an unfolded state to a folded state, the second part 512 of the elastic member 51 always remains in close contact with the surface of the screen module 40, so that there are no gaps at the position where the second part 512 of the elastic member 51 contacts the surface of the screen module 40. In particular, the second part 512 is in close contact with the foldable display part 43, and foreign objects from the outside cannot enter the interior of the foldable electronic device 1 from this area.

[0188] Figure 20 and Figure 21 This is a partially schematic exploded view of another foldable electronic device provided in an embodiment of this application. Figure 22 yes Figure 21 Cross-sectional view.

[0189] refer to Figures 20 to 22 In order to further improve the firmness of the elastic member 51 in the foldable electronic device 1, a protrusion 101 is provided on the surface of the first middle frame 10 facing the elastic member 51 along the second direction, and a receiving portion 5133 is provided at the position corresponding to the protrusion 101 in the third part 513 of the elastic member 51, and the protrusion 101 is received in the receiving portion 5133.

[0190] It is understood that the receiving groove 5133 can be regarded as a structure extending from the second extension 5132 along the axial direction of the rotating shaft assembly 30. For example, it can be a through hole that passes through in the second direction. When the elastic member 51 is installed in the foldable electronic device 1 along the second direction, the protrusion 101 passes through the through hole and fixes the elastic member 51 on the first middle frame 10. The protrusion 101 is adapted to the receiving part 5133. The adaptation here includes the adaptation of shape and size.

[0191] It should be noted that, for aesthetic and lightweight design considerations, the first middle frame 10 of the foldable electronic device 1 is usually made of aluminum-based composite material. However, such material has low hardness and may be relatively soft. When the foldable electronic device 1 is subjected to external force, it is easy to deform. The protrusion 101 may also be affected and deformed. At this time, the fit between the receiving part 5133 and the protrusion 101 will decrease, causing the elastic element 51 to be unable to be properly fixed in the first middle frame 10.

[0192] Figure 23 This is a partially schematic exploded view of another foldable electronic device provided in an embodiment of this application. Figure 24 yes Figure 23 Cross-sectional view in the y-direction.

[0193] refer to Figure 23 as well as Figure 24 To solve the above problems, a protrusion 101a is provided on the surface of the first middle frame 10 facing the elastic member 51 along the second direction. The protrusion 101a is fixedly connected to the first middle frame 10. The hardness of the protrusion 101a is greater than the hardness of the first middle frame 10. The arrangement of the receiving part 5133 is the same as described above, and will not be repeated here.

[0194] Still Figure 23 as well as Figure 24 As shown, the protrusion 101a and the first middle frame 10 are respectively set as two parts, and the protrusion 101a can be fixed in the first middle frame 10 by welding.

[0195] The protrusion 101a can be made of a material with a higher hardness than the first middle frame 10, for example, it can be made of stainless steel.

[0196] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
