Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of communication equipment, and in particular to a decorative component, an electronic device, and an assembly method of the electronic device. Background Art

[0002] At present, electronic devices have more and more functions and more and more complex designs. In order to meet certain functional requirements or design requirements, electronic devices will set decorative parts on one side of the display screen. Such decorative parts are also called cover decorative parts. Cover decorative parts are widely used in folding screen electronic devices. At present, the decorative cover plates in folding screen electronic devices have problems such as unstable installation or complicated installation methods, which leads to insufficient appearance of the product. Summary of the invention

[0003] The embodiments of the present application provide an electronic device and an assembly method of the electronic device with a display screen side decorative piece reliably fixed.

[0004] An embodiment of the present application provides an electronic device, including a middle frame, a display screen and a decorative member are installed on the first side of the middle frame, the decorative member includes a first surface, a second surface and a mounting body, the first surface is used to form a partial appearance surface of the electronic device, the second surface is located on the side of the decorative member away from the first surface and between the plane where the first surface and the display screen are located, and the mounting body protrudes from the second surface, wherein the middle frame also has a through hole, the through hole runs through the thickness direction of the middle frame, and the mounting body is at least partially located inside the through hole of the middle frame. The electronic device also includes a limiting structure, and the mounting body is also locked with the middle frame through the limiting structure. Among them, the thickness direction of the middle frame is roughly perpendicular to the direction of the plane where the display screen is located, or the arrangement direction of the display screen and the back cover. In a specific example, the mounting body can be locked with the middle frame through the limiting structure at the end away from the display screen. Of course, the mounting body can be partially locked with the middle frame, and the mounting body can also be completely locked with the middle frame.

[0005] In the embodiment of the present application, a through hole is provided on the middle frame, and a limiting structure can be installed from the side of the through hole away from the display screen to achieve locking of the mounting body and the middle frame. In this way, the setting flexibility of the limiting structure is relatively high and does not affect the appearance surface of the middle frame. After the mounting body is locked with the middle frame through the limiting structure, the mounting body can be restricted from being separated from the middle frame, thereby improving the reliability of fixing the decorative part and the middle frame.

[0006] In addition, in the embodiment of the present application, the mounting body of the decorative component is at least partially located inside the through hole, and can also be completely located inside the middle frame without affecting the external structure of the middle frame. The design flexibility of the middle frame can be relatively high, and the processing accuracy of the mounting body can be relatively low, and the processing cost can be relatively low.

[0007] In one example, the end of the mounting body away from the display screen is snap-connected to the hole wall of the through hole through a limiting structure. The snap-connection has high fixing reliability and is easy to implement.

[0008] In one example, the limiting structure includes a block, the block is at least partially located in the assembly path of the installation body, and the block is limitedly connected to the hole wall of the through hole, wherein the main function of the block is to limit the installation body from escaping from the through hole. The assembly path in this application refers to the path of the installation body inserted into the through hole. In the embodiment of the present application, by arranging the block on the assembly path of the installation body, it is possible to prevent the installation body from escaping from the through hole along the assembly direction, and the structure is simple.

[0009] In one example, the block is formed between the mounting body and the middle frame by solidifying a fluid material. The fluid material is a material that can be deformed, can flow spontaneously or can flow under certain conditions. For example, the fluid material can be plastic, glue or plasticine. The plastic is filled between the mounting body and the middle frame by injection molding and extrusion, and forms a plastic block after solidification. The glue is filled between the mounting body and the middle frame by injection molding or extrusion, and forms a glue block after solidification. The plasticine can also be filled between the mounting body and the middle frame by extrusion and other means, and forms a plasticine block after solidification.

[0010] In this way, the decorative part can fill the fluid material between the mounting body and the middle frame after the mounting body and the middle frame are assembled, and then solidify to form a block that serves as a limiter. In this way, when the mounting body and the middle frame are assembled, they are not restricted by the limiting structure and are easy to install.

[0011] In one example, the outer wall of the mounting body has a recessed portion, the hole wall of the through hole has a recessed cavity, the recessed portion and the recessed cavity enclose a receiving space, and at least part of the block can be formed inside the receiving space. In the embodiment of the present application, the recessed portion is formed on the mounting body, and the volume occupied by the mounting body is relatively small. Correspondingly, the recessed cavity is formed on the hole wall of the through hole, and the size of the through hole can also be relatively small, occupying a small volume of the middle frame, and the strength of the middle frame can be relatively high, which is conducive to improving the overall performance of the electronic device.

[0012] In one example, the recessed portion has a first wall, the first wall faces the display screen, and the cavity wall of the recessed cavity includes a second wall, the second wall faces the middle frame back cover, that is, the first wall and the second wall face opposite directions, and the first wall and the second wall are arranged along the thickness direction, so that a partial area of ​​the accommodating space is formed between the first wall and the second wall, and the block is at least partially located between the first wall and the second wall. The projections of the first wall and the second wall in a plane perpendicular to the thickness direction of the middle frame may partially overlap, and of course, the projections of the first wall and the second wall in a plane perpendicular to the thickness direction of the middle frame may not overlap.

[0013] In the embodiment of the present application, the first wall and the second wall are two opposite inverted surfaces. When the decorative component is subjected to external force, the block can lean against the first wall to inhibit the first wall from moving upward relative to the through hole. At the same time, the second wall generates a downward force on the block, which can offset part of the force exerted by the first wall on the block. The above structure of the present application can provide a relatively large anti-deformation force to form a reliable and stable fixed connection structure.

[0014] In one example, the first wall may be a plane, and the second wall may also be a plane, that is, both the first wall and the second wall may be planes, and the first wall and the second wall are parallel to the plane where the display screen is located. When the electronic device is a folding screen electronic device, the first wall and the second wall are parallel to the display screen in the unfolded state. In the embodiment of the present application, the plane structure is relatively simple to process. Of course, the structure of the first wall and the second wall is not limited to a plane, but can also be a curved surface.

[0015] In one example, the middle frame further includes a second side, the first side and the second side are located on both sides of the middle frame along the thickness direction thereof, the through hole forms a first opening end on the first side, and the through hole forms a second opening end on the second side, that is, the through hole passes through the first side and the second side of the middle frame. The recessed cavity extends to the second opening end, so that the block can be placed into the recessed cavity from the second opening end of the second side, and the structure is simple.

[0016] In one example, an injection channel is also formed between the mounting body and the corresponding cavity wall of the recessed cavity, one end of the injection channel is connected to the accommodating space, and the other end is connected to the second opening end. In this way, in the embodiment of the present application, the injection channel is formed between the mounting body and the cavity wall of the recessed cavity, and there is no need to open another channel on the middle frame for glue injection, which simplifies the middle frame processing technology and is beneficial to improving the use strength of the middle frame.

[0017] In one example, along the assembly direction of the mounting body, the through hole is a stepped hole, the stepped hole includes a first hole section and a second hole section, the first hole section and the second hole section are connected by a stepped surface, the recessed cavity can be a part of the second hole section, and of course, the recessed cavity can also be the entire second hole section. The stepped surface is a second wall, and the second wall faces the second opening end, the mounting body includes a first column section and a second column section connected, the first column section and the first hole section are circumferentially matched, the first column section and the first hole section can be circumferentially fitted and contacted, and of course, the first column section and the second hole section can also be circumferentially gapped. The second column section is located in the second hole section, and the recessed portion is located in the second column section. In the embodiment of the present application, the first column section and the first hole section match in shape, and the two are basically fitted or have a small gap in the circumferential direction, so that the accommodation space formed by the recessed portion and the recessed cavity is located on one side of the first hole section and is basically a closed structure, the injected fluid material basically does not flow between the first hole section and the first column section, and the fluid material entering from the second opening end is basically between the recessed portion and the recessed cavity, which is conducive to improving the solidification molding quality of the fluid material forming the block, thereby improving the reliability of the locking of the mounting body and the through hole.

[0018] In one example, the limiting structure is directly formed by the decorative part, the end of the mounting body away from the second surface is plastically deformed to form the limiting structure, and the end of the mounting body away from the second surface is plastically deformed to be snap-connected to the hole wall. This embodiment directly uses the mounting body structure to form the limiting structure, has a small number of parts, and is conducive to reducing the weight of the whole machine.

[0019] In one example, the outer side wall of the middle frame where the decorative piece is provided is an inclined surface, and at least the outer side wall of the section where the middle frame is provided with the through hole has an inclined surface, and the inclined surface has an angle with the thickness direction of the middle frame, and the axial direction of the through hole is substantially the same as the inclined direction of the inclined surface. In this way, the distance from the through hole to the inclined surface is substantially the same at all locations along the thickness direction of the electronic device, the overall strength of the middle frame is relatively high, and the extending direction of the through hole is the same as the inclined surface, and the second opening end of the through hole can be located in the rear cover covering area, which does not affect the overall appearance of the device.

[0020] In one example, the decorative piece includes a side segment, the side segment is a straight segment, at least one end of the side segment along its length is connected to a turning segment, and both ends of the side segment can be provided with turning segments, and the mounting body is located in the side segment. During assembly, the turning segment of the decorative piece usually corresponds to the corner portion of the middle frame. In the present application, the mounting body is arranged in the side segment to avoid the corner portion of the middle frame, which can improve the use strength of the corner portion of the middle frame.

[0021] In one example, both ends of the side segment along its length are connected to the turning segment, the number of the mounting bodies is at least two, and the mounting position of the mounting body on the side segment is close to one side of the turning segment, for example, the mounting body can be installed at a position 0 to 10 mm away from the turning segment. In this way, the reliability of the fixing of the decorative part is improved as much as possible without affecting the strength of the corner portion of the middle frame.

[0022] In one example, the second surface has a support area, and the decorative member is supported by contacting the middle frame through the support area; the decorative member also includes an extension section, which extends from the support area toward one side of the display screen, and the extension section can block the gap between the corresponding side of the display screen and the middle frame, that is, the extension section at least partially extends above the display screen, and the corresponding side of the display screen is located between the extension section and the middle frame. For a folding screen electronic device, the corresponding side of the display screen slides back and forth between the extension section and the middle frame. In the embodiment of the present application, the decorative member covers the gap between the corresponding side of the display screen and the middle frame through the extension section, which improves the appearance of the electronic device to a certain extent.

[0023] In one example, an elastic cushion is provided on the surface of the extension section facing the display screen, and the elastic cushion can be a cushioning and wear-resistant component such as silicone, rubber, or film, and the extension section contacts the display screen through the elastic cushion, so as to reduce the wear of the extension section on the display screen and protect the display screen.

[0024] In one example, an adhesive layer is provided between the support area and the middle frame. In this embodiment, the support area of ​​the decorative element is further fixed to the middle frame through the adhesive layer, thereby improving the fixing reliability of the decorative element.

[0025] In one example, the support area further has a boss, the height of the boss is less than the height of the mounting body, the middle frame is further provided with a groove, the boss is located inside the groove, and the boss and the groove are bonded and fixed. The corresponding surfaces of the boss and the groove are bonded and fixed by adhesive, which further increases the bonding area between the decorative part and the middle frame, and improves the reliability of the fixing of the decorative part.

[0026] In one example, the first side of the middle frame has a raised frame body, and the frame body is located at the periphery of the display screen. For a rectangular electronic device, the frame body is roughly surrounded by a rectangular frame, and the frame body includes side portions, and adjacent side portions are connected by corner portions. The groove includes a first groove and a second groove, and the first groove is located at the side, and the second groove is located at the corner portion. The depth of the second groove is less than the first groove. Along the length direction of the decorative part, the boss includes a first boss and a second boss, which are respectively located in the first groove and the second groove, and the height of the first boss is higher than the second boss. In the embodiment of the present application, the depth of the second groove near the corner portion of the electronic device is shallower than that of other positions, so that the strength of the middle frame at the corner portion is relatively high, which is conducive to improving the use strength of the corner portion of the electronic device and improving the force strength of the corner portion.

[0027] In one example, a groove side wall of the second groove on a side close to the display screen has a first notch to avoid the display screen, so that a larger display screen size can be obtained.

[0028] In one example, the through hole is located at the side portion, and the through hole is set to avoid the corner portion as much as possible, which is helpful to improve the use strength of the corner portion of the middle frame.

[0029] In one example, the sidewall of the first groove is further provided with a second notch, which is used as a reference structure for the glue filling device to perform glue filling work. The glue injection or dispensing device can use the second notch as a reference point to perform rapid glue injection or dispensing work.

[0030] In one example, the electronic device is a folding screen electronic device, which includes a rotating shaft, and middle frames are provided on both sides of the rotating shaft. The display screen is slidably supported on the two middle frames. Under the action of the rotating shaft, the two middle frames are relatively folded or unfolded to drive the display screen to slide back and forth relative to the two middle frames. The sides of the two middle frames parallel to the axial direction of the rotating shaft are provided with decorative parts to cover the gap between the corresponding side of the display screen and the middle frame. In this embodiment, the decorative plate not only plays a decorative role, but also assists in positioning the side of the display screen to improve the stability of the display screen when sliding relative to the middle frame.

[0031] In the second aspect, the embodiment of the present application further provides a decorative piece, which is installed on one side of the display screen of the electronic device. The decorative piece includes a first surface, which is mainly used to form a partial appearance surface of the electronic device, and the first surface and the display screen are located on the same side of the middle frame. The decorative piece also includes a second surface, which is located on the side of the decorative piece away from the first surface. The second surface is provided with a mounting body, which protrudes from the second surface. The mounting body is mainly used to be set inside a through hole on the middle frame, and the mounting body is locked with the middle frame through a limiting structure. In one example, the end of the mounting body away from the second surface is locked with the middle frame through the limiting structure. For example, the end of the mounting body away from the second surface passes through the through hole and is located on the second side of the middle frame, and the end is fixed to the middle frame through the limiting structure.

[0032] In an embodiment of the present application, the decorative piece has a mounting body inserted into the through hole of the middle frame, and the limiting structure can be installed from the side of the through hole away from the display screen to limit the mounting body from escaping from the through hole, thereby improving the flexibility of the setting of the limiting structure and improving the reliability of fixing the decorative piece.

[0033] In one example, the mounting body includes a first column segment and a second column segment, the first body and the second column segment are connected, the second column segment is located at one end of the first column segment away from the second surface, the first column segment is used to circumferentially cooperate with the corresponding hole segment on the middle frame, the second column segment is provided with a recessed portion, and the limiting structure is at least partially located in the recessed portion. The recessed portion is located at the end away from the display screen, which facilitates the installation and setting of the limiting structure.

[0034] In one example, the decorative piece includes a side section and a bend section, the side section is a straight section, the bend section is connected to the end of the side section along its length direction, and the mounting body is located in the side section. During assembly, the bend section is substantially opposite to the corner portion of the middle frame, and in this embodiment, the mounting body is arranged to avoid the bend section, and accordingly, the through hole on the middle frame is arranged to avoid the corner portion, which is conducive to improving the use strength of the corner portion.

[0035] In one example, both ends of the side segment are connected to the turning segment, and a mounting body is provided at least at the position of the turning segment close to the side segment, that is, at least two mounting bodies are provided on the decorative member, which are located at the two ends of the side segment. Of course, mounting bodies can also be provided at other positions of the side segment. In theory, the more mounting bodies there are, the more reliable the fixing of the decorative member is, but the structure of the decorative member and the middle frame is also more complicated. Only providing mounting bodies at the two ends of the side segment can simplify the structure of the decorative member and the middle frame under the premise of reliable fixing.

[0036] In one example, the second surface has a support area, the decorative member is supported on the middle frame through the support area, and the decorative member further includes an extension section for shielding the gap between the corresponding side of the display screen and the middle frame, and the extension section extends from the support area toward one side of the display screen. In this embodiment, the decorative member can shield the gap between the display screen and the middle frame, thereby improving the appearance quality of the electronic device.

[0037] In one example, the second surface further has a boss, the height of the boss is less than the height of the mounting body, during assembly, the boss is located inside the groove of the middle frame, and the boss and the groove are bonded and fixed, and the boss and the groove can be bonded and fixed by adhesive. The bonding and fixing of the boss and the groove further improves the reliability of the fixing of the decorative part to the middle frame.

[0038] In a third aspect, an embodiment of the present application further provides a method for assembling any of the above electronic devices, comprising:

[0039] Assemble the display screen on one side of the middle frame;

[0040] Inserting at least part of the mounting body of the decorative element into the through hole of the middle frame, and supporting the decorative element on the first side of the middle frame;

[0041] A limiting structure is installed on a side of the through hole away from the display screen, so that the limiting structure locks the installation body and the middle frame.

[0042] In the embodiment of the application, a through hole is provided on the middle frame, and the limiting structure can be installed from the side away from the display screen to achieve locking of the decorative part and the middle frame. The limiting structure is easy to install, and the installation body and the limiting structure can be located inside or at the rear of the middle frame without affecting the appearance surface of the middle frame.

[0043] In one example, the limiting structure is formed by:

[0044] Fill the fluid material between the mounting body and the middle frame, and solidify to form a limiting structure. As described above, the limiting structure can be formed by filling the fluid material between the decorative part and the middle frame after the decorative part and the middle frame are assembled, so that the assembly of the decorative part and the middle frame is not affected by the limiting structure, and the flexibility is relatively high.

[0045] In one example, the electronic device further includes a back cover, and after the limiting structure is solidified, the following steps are further performed:

[0046] Install the rear cover onto the side of the middle frame away from the display.

[0047] The assembly method of the electronic device provided in the embodiment of the present application is based on the above-mentioned electronic device, and the decorative component is used for the above-mentioned electronic device, so the assembly method and the decorative component also have the above-mentioned technical effects of the electronic device.

[0079] Please refer to Figure 1It is understood that the folding screen electronic device includes a middle frame 1, a rotating shaft 4 and a display screen 2. The display screen 2 is supported on one side of the middle frame 1. The display screen 2 includes a middle section 2-2 and free sections 2-1 connected to both sides of the middle section 2-2. The middle section 2-2 corresponds to the rotating shaft. When the folding screen electronic device is folded or unfolded, the first middle frame 11 and the second middle frame 12 will rotate around the central axis P, and at the same time drive the two free sections 2-1 to rotate around the central axis P, so that the display screen is in an unfolded state and a folded state. During the folding or unfolding process, the relative position of the middle section 2-2 and the rotating shaft 4 remains roughly unchanged, and the two can be fixed.

[0080] According to the different positions of the display screen 2 after the folding screen electronic device is folded, the folding screen electronic device can be divided into an external folding electronic device and an internal folding electronic device, wherein Figure 2 As shown, when the external folding electronic device is in a folded state, the display screen 2 is located outside the middle frame 1 (the first middle frame 11 and the second middle frame 12); Figure 3 As shown, when the inner folding electronic device is in a folded state, the display screen 2 is folded between the first middle frame 11 and the second middle frame 12 .

[0081] comprehensive Figure 1 , Figure 2 and Figure 3 It can be seen that no matter it is an external folding electronic device or an internal folding electronic device, when the display screen 2 is in the flattened state, the display screen 2 is basically flattened into a plane. When the display screen 2 is in the folded state, the connecting section 2-11 of the free section 2-1 close to the middle section 2-2 will bend into an arc shape.

[0082] Since the rotation radius of the first middle frame 11 and the second middle frame 12 is not exactly the same as the rotation radius of the display screen 2, in order to meet the folding deformation requirements of the display screen 2, the two free sections 2-1 need to be able to slide relative to the middle frame 1, so that during the folding process or the unfolding process, the distance between the first side edge 2a of the display screen 2 and the side wall 11a of the first middle frame 11, and between the second side edge 2b and the side wall 12a of the second middle frame 12 is variable. In at least one of the unfolding and folding states, there will inevitably be gaps between the first side edge 2a and the side wall 11a of the first middle frame 11, and between the second side edge 2b and the side wall 12a of the second middle frame 12. Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 FIG. 2 shows a distance m between the first side edge 2a and the side wall 11a of the first middle frame 11 in a flattened state. Figure 2 FIG. 2 shows that the outer foldable electronic device is in a folded state, and the distance m1 between the first side edge 2a and the side wall 11a of the first middle frame 11 is Figure 3It shows that when the inner folding electronic device is in a folded state, the distance m2 between the first side edge 2a and the side wall 11a of the first middle frame 11. For the outer folding electronic device, m is less than m1, and for the inner folding electronic device, m is greater than m2.

[0083] In order to improve the aesthetics and overall performance of foldable screen electronic devices, a decorative part 3 is usually added to the middle frame 1 to cover the gap between the display screen 2 and the middle frame 1.

[0084] The inventor of the present application has conducted a lot of research and found that there are generally two ways to set the current decorative element 3:

[0085] For the first method, please refer to Figure 4 , Figure 4 for Figure 1 A1-A1 cross-sectional view of the A' region of the electronic device shown; the decorative piece 3 is generally a U-shaped structure. After the decorative piece 3 is assembled with the middle frame 1, one end of the middle frame 1 is located inside the opening of the U-shaped structure, and then the groove wall of one side of the U-shaped structure close to the back cover 7 is fixed to the middle frame 1 using screws 4'. This method has a relatively complex structure of the decorative piece 3, and requires precision stamping, computerized numerical control (CNC), rough, medium and fine polishing, two-color coating and other processes during processing. The manufacturing process is relatively long and the cost is relatively high.

[0086] For the second method, please refer to Figure 5 , Figure 5 A partial cross-sectional diagram of another electronic device in the current technology, wherein the cross-sectional position is Figure 1 The position of A' is the same. The decorative part 3 is roughly a plate structure. The combination position of the decorative part 3 and the middle frame 1 is fixed by adhesive. In order to expand the adhesive area, a sol groove 11' is sometimes provided on the middle frame 1. The decorative part 3 may have a protrusion 31' in part, and the protrusion 31' is located inside the sol groove 11'. The decorative part 3 is adhesively fixed to the middle frame 1. After a period of use, the adhesive is prone to failure, the adhesive position is prone to cracking and warping, and there is even a risk of partial falling off of the adhesive, and the fixing reliability is relatively poor. In addition, in order to meet the bonding strength of the decorative part and the middle frame, the thickness of the adhesive is also relatively thick, resulting in a relatively thick thickness of the entire machine, which in turn affects the quality of the entire machine.

[0087] Therefore, how to overcome at least one of the above-mentioned defects is a technical problem that needs to be solved urgently by technicians in this field.

[0088] On the basis of the above research findings, the inventors of the present application explored and carried out a large number of experiments, and proposed an electronic device in which the decorative parts located on the display side have a relatively high fixing reliability, which is conducive to improving the quality of the entire device.

[0089] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present application, the embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The embodiments of the present application do not impose any special restrictions on the specific form of the above-mentioned terminal devices. For ease of understanding, the following description is made by taking the electronic device as a mobile phone as an example.

[0091] The following is an example of the electronic device provided in the embodiment of the present application being a folding screen electronic device to further introduce the technical solution and technical effects. Of course, those skilled in the art should understand that the technical solution of the embodiment of the present application can be applied to folding screen electronic devices as well as non-folding screen electronic devices.

[0092] See also Figure 6 , Figure 6 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application.

[0093] The folding screen electronic device 100 in the embodiment of the present application includes a middle frame 1, a display screen 2 and a rotating shaft 4, wherein the middle frame 1 includes two parts: a first middle frame 11 and a second middle frame 12, the first middle frame 11 and the second middle frame 12 are respectively located on both sides of the rotating shaft 4, and the first middle frame 11 and the second middle frame 12 are connected by the rotating shaft 4. Under the action of the rotating shaft 4, the first middle frame 11 and the second middle frame 12 can be relatively folded and unfolded, thereby realizing the folding or unfolding of the folding screen electronic device, wherein Figure 6 The axial direction S1 of the rotating shaft 4 is shown in FIG. The first middle frame 11 and the second middle frame 12 may have a receiving cavity 1a (see Figure 8), the mainboard, processor, internal memory, charging management module, power management module, battery and other electronic devices (not shown in the figure) of the folding screen electronic device 100 can be installed inside the accommodating cavity 1a of the first middle frame 11 and the second middle frame 12, and the display screen 2 is arranged on one side of the first middle frame 11 and the second middle frame 12. The first middle frame 11 and the second middle frame 12 play the role of supporting and protecting various electronic devices.

[0094] Please refer again Figure 6 In the embodiment of the present application, the first middle frame 11 may include a metal body 111 and a plastic body 112. The metal body 111 is partially disconnected, and the plastic body 112 is filled in the disconnected position, so that the first middle frame 11 can be used as an antenna or other functional requirements. The function of the partial disconnection of the metal body 111 of the first middle frame 11 is not described in detail in this application, and reference may be made to the current information.

[0095] In the embodiment of the present application, the structures of the second middle frame 12 and the first middle frame 11 may be the same, but may not be completely the same. The specific structures of the two middle frames may be stable according to the specific product.

[0096] The display screen 2 includes two side edges parallel to the axial direction S1, and the two side edges are respectively defined as a first side edge 2a and a second side edge 2b. When the folding screen electronic device is unfolded or folded, the display screen 2 can slide back and forth relative to the two middle frames (the first middle frame 11 and the second middle frame 12). For example, when the folding screen electronic device is unfolded, the two ends of the display screen 2 will slide outward to the first position. At this time, the first side edge 2a of the display screen 2 is at a distance m from the side wall 11a of the first middle frame 11, and the second side edge 2b of the display screen 2 is at a distance m from the side wall 12a of the second middle frame 12. For the folding screen electronic device that is an external folding electronic device, at this time, the distance between the first side edge 2a and the side wall 11a of the first middle frame 11, and the distance between the second side edge 2b and the side wall 12a of the second middle frame 12 is the smallest. For the folding screen electronic device that is an internal folding electronic device, at this time, the distance between the first side edge 2a and the side wall 11a of the first middle frame 11, and the distance between the second side edge 2b and the side wall 12a of the second middle frame 12 is the largest. During the folding or unfolding process, the schematic diagram of the external folding electronic device and the internal folding electronic device after folding can be referred to. Figure 2 and Figure 3 , no further details will be given here. Similarly, for the change in the distance between the display screen and the middle frame 11, please refer to the background technology description.

[0097] Please refer again Figure 6Typically, the first side of the first middle frame 11 and the second middle frame 12 both have a frame 10, the frame 10 is located outside the display screen 2, and the display screen 2 is located in the space surrounded by the frame 10. Specifically, except for one side close to the shaft 4, the other three sides of the first middle frame 11 and the second middle frame 12 are both provided with a frame 10. The frame 10 of the first middle frame 11 includes three side portions 101, and adjacent side portions are connected by a corner portion 102.

[0098] Please refer again Figure 6 In the embodiment of the present application, in order to cover the gap between the first side 2a and the side wall 11a of the first middle frame 11, and the gap between the second side 2b and the side wall 12a of the second middle frame 12, a decorative piece 3 is also provided on the first middle frame 11 and the second middle frame 12. The first side 2a of the display screen 2 slides between the decorative piece 3 and the first middle frame 11, and the second side 2b slides between the decorative piece 3 and the second middle frame 12 on the other side.

[0099] Please refer to Figure 7 The display screen 2 includes a display module 22 and a transparent cover plate 21. The display module 22 can display images and videos, etc. The display module 22 can use a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a quantum dot light-emitting diode (QLED), an electrophoretic display technology (E-Ink), etc. The display screen 2 of the current folding screen electronic device mostly uses OLED. The transparent cover plate 21 covers the outside of the display module and plays a role in protecting the display module 22. The transparent cover plate 21 can be a glass cover plate, and of course it can also be other transparent materials that can play a protective function. For example, the transparent cover plate 21 can be a transparent polyimide. The display screen 2 can also have a touch function, that is, the display screen 2 can be a touch screen.

[0100] Please refer to Figure 7, usually the transparent cover plate 21 completely covers the display module 22, and the outer contour of the transparent cover plate 21 is larger than the outer contour of the display module 22, wherein the solid line in the figure is the outer contour of the transparent cover plate 21, and the dotted line is the outer contour of the display module. The transparent cover plate 21 has a cover plate segment 211 extending from the display module 22 and separated on both sides, and the cover plate segment 211 is slidably supported on the middle frame 1. For example, each middle frame is provided with two step surfaces 113 ( Figure 8 Only one step surface is shown in FIG. 1 ), the cover plate segment 211 of the transparent cover plate 21 is slidably supported on the step surface 113, please refer to Figure 8 , Figure 8 for Figure 6 A is an exploded schematic diagram. The transparent cover plate 21 and the display module 22 can be fixed by bonding, for example, the two are bonded and fixed by optically clear adhesive (OCA).

[0101] Please refer to Figure 8 and Fig. 9 , Figure 8 for Figure 6 The local decomposition diagram at A in the middle, Fig. 9 for Figure 6 A partial schematic diagram of the middle part; the figure shows the decorative piece 3 supported on the first middle frame 11, which is mainly used to block the gap between the first side 2a of the display screen 2 and the side wall of the first middle frame 11. The structure of the decorative piece 3 provided on the second middle frame 12 can be the same as that of the decorative piece 3 on the first middle frame 11, or of course it can be different.

[0102] Please refer to Fig.10 , Fig.10 for Fig. 9 DD cross-sectional view. In the embodiment of the present application, the decorative element 3 includes a first surface 31, and the first surface 31 is used to form a partial appearance surface of the electronic device. For a folding screen electronic device, at least when the display screen 2 is in the unfolded state, the appearance surface formed by the decorative element 3 is located outside the folding screen electronic device. When the display screen 2 is in the folded state, the first surface 31 can be partially or completely folded inside the middle frame. In the embodiment of the present application, the first surface 31 and the display screen 2 are located on the same side of the middle frame 1. Fig.10 In particular, the first surface 31 and the display screen 2 are located on the same side of the first middle frame 11. Usually, the middle frame 1 and the display screen 2 have different colors. In order to make the outer surface of the electronic device have a better visual effect, in the embodiment of the present application, the first surface 31 can be processed by a two-color coating process. Under the effect of the first surface 31, the overall appearance color of the electronic device gradually transitions from the display screen 2 to the middle frame 1.

[0103] The decorative member 3 further includes a second surface 32 and a mounting body 34. The second surface 32 is located on the side of the decorative member 3 away from the first surface 31, that is, the second surface 32 and the first surface 31 are located on both sides of the decorative member 3 along the thickness direction S3 of the decorative member 3. The mounting body 34 protrudes from the second surface 32, that is, the mounting body 34 extends from the second surface 32 toward the second side of the first middle frame 11. The mounting body 34 may be a columnar structure, and the specific structure of the mounting body 34 may be determined according to the specific structure of the electronic device.

[0104] In the embodiment of the present application, the first middle frame 11 has a through hole 115, and the through hole 115 runs through the thickness direction of the first middle frame 11. The electronic device also includes a limiting structure 5, which is fixedly connected to the first middle frame 11, and the mounting body 34 is locked with the first middle frame 11 through the limiting structure 5 to limit the movement of the mounting body 34 along the first direction, wherein the first direction is the opposite direction to the assembly direction of the mounting body 34 (the direction of inserting the through hole 115). The limiting structure 5 can be a block, a limiting pin, or an elastic protrusion. Of course, the limiting structure 5 can also be formed by the structures on the mounting body 34 and the first middle frame 11.

[0105] In the embodiment of the present application, a through hole 115 is provided on the middle frame, and the limiting structure 5 can be installed from the side of the through hole 115 away from the display screen 2 to achieve locking of the mounting body 34 and the first middle frame 11. In this way, the setting flexibility of the limiting structure 5 is relatively high, and does not affect the appearance surface of the first middle frame 11. After the mounting body 34 is locked with the first middle frame 11 by the limiting structure 5, the mounting body 34 can be restricted from being separated from the first middle frame 11, thereby improving the reliability of fixing the decorative component 3 and the first middle frame 11.

[0106] In addition, in the embodiment of the present application, the mounting body 34 of the decorative component 3 is at least partially located inside the through hole 115, and can also be completely located inside the first middle frame 11, without affecting the external structure of the first middle frame 11. The design flexibility of the first middle frame 11 can be relatively high, and the processing accuracy of the mounting body 34 can be relatively low, and the processing cost can be relatively low.

[0107] In the embodiment of the present application, the mounting body of the decorative component 3 can be snap-fitted with the middle frame through the limiting structure 7, so as to limit the mounting body 34 from being separated from the middle frame 1. For example, the mounting body 34 and the hole wall of the through hole 34 are snap-fitted through the limiting structure 7, and the snap-fit ​​locking force is relatively high, which can improve the reliability of the fixing of the decorative component 3.

[0108] In the embodiment of the present application, the mounting body 34 is at least partially located inside the through hole 115, that is, the mounting body 34 of the decorative element 3 is located inside the through hole 115, and can be completely located inside the middle frame 1.

[0109] In the embodiment of the present application, the limiting structure 5 may include a block, the block is at least partially located in the assembly path of the mounting body 34, and the block is limitedly connected to the hole wall of the through hole 115 to limit the mounting body 34 from escaping from the through hole 115. The block and the through hole 115 may be limited by gluing or snapping, as long as the mounting body 34 and the first middle frame 11 can be locked in position to prevent the mounting body 34 from escaping from the through hole 115. The block limiting structure is simple and occupies little space.

[0110] In the embodiment of the present application, the block can be solidified and formed between the mounting body 34 and the first middle frame 11 by a fluid material, and the fluid material is a material that can be deformed under certain conditions, such as glue, plasticine, or plastic. The glue can be acrylic resin quick-drying glue, epoxy resin AB glue, or polyurethane hot melt glue, and the plastic can be polystyrene, polypropylene, or polyethylene.

[0111] In the embodiment of the present application, after the mounting body 34 is installed in the first middle frame 11, the fluid material is filled on the assembly path of the mounting body 34, and after the filling is completed, it is solidified to form a block. After the block is formed, it will hinder the movement of the mounting body 34 along the first direction, and then inhibit the mounting body 34 from escaping from the through hole, thereby fixing the decorative part 3.

[0112] The filling of the fluid material and the curing process can be performed after the mechanical parts such as the decorative part 3 are assembled, and then the block is formed. In this way, the decorative part 3 is not restricted by the limiting structure 5 during assembly, and the installation is convenient.

[0113] Different fluid materials may have different filling processes. For example, when the fluid material is glue, the glue can be filled into the corresponding positions of the mounting body 34 and the first middle frame 11 through a glue injection process; for example, when the fluid material is plastic material, the fluid plastic can be filled into the corresponding positions of the mounting body 34 and the first middle frame 11 through a plastic injection process. For example, when the fluid material is plasticine, the plasticine can be squeezed into the corresponding positions of the mounting body 34 and the first middle frame 11 through an extrusion process.

[0114] Please refer to Fig.10 The electronic device of the present application is further provided with a back cover 7, which is located on the side of the middle frame away from the display screen 2, that is, the back cover 7 is located on the second side of the middle frame 1. The first middle frame 11 and the second middle frame 12 are both provided with a back cover 7, and the back cover 7 is connected to the corresponding middle frame 1 by snaps or other means.

[0115] Please combine Fig.11 It is understood that in the embodiment of the present application, the outer wall of the mounting body 34 has a recessed portion 34a, the recessed portion 34a has a first wall 341, the first wall 341 faces the display screen 2, and the first wall 341 is engaged with the block body, such as Fig.11As shown, the recessed portion 34a includes not only the first wall 341 but also a vertical wall 342 perpendicular to the first wall 341. The recessed portion 34a can be arranged as far as possible at the end of the mounting body 34 away from the second surface 31. After the block is formed, the first wall 341 and the block are buckled against each other to lock the position of the mounting body 34.

[0116] In the embodiment of the present application, a recessed portion 34a is processed on the mounting body 34 to form a first wall 341 that fits with the block and snaps into place. The structure is simple, and the volume occupied by the mounting body 34 is small. Accordingly, the size of the through hole 115 can also be small, and the volume occupied by the middle frame 1 is small. The strength of the middle frame 1 can be relatively high, which is beneficial to improving the overall performance of the folding screen electronic device.

[0117] Please combine Fig.10 and Fig.12 It is understood that in the embodiment of the present application, the hole wall of the through hole 34 has a recessed cavity 115a, and the block is simultaneously formed inside the accommodating space enclosed by the recessed portion 34a and the recessed cavity 115a. The cavity wall of the recessed cavity 115a includes a second wall 115a1, and the second wall 115a1 is opposite to the first wall 341. The second wall 115a1 faces the second side of the first middle frame 11, and the block is at least partially located between the first wall 341 and the second wall 115a1.

[0118] In the embodiment of the present application, the first wall 341 and the second wall 115a1 are two inverted surfaces. When the decorative component 3 is subjected to external force, the block can lean against the first wall 341 to suppress the upward movement of the first wall 341 relative to the through hole 115. At the same time, the second wall 115a1 generates a downward force on the block, which can offset part of the force of the first wall 341 acting on the block. The above-mentioned structure of the present application can provide huge anti-deformation force to form a reliable and stable fixed connection structure.

[0119] In the embodiment of the present application, the first wall 341 and the second wall 115a1 can be both planes and parallel to the display screen 2 in the unfolded state. The first wall 341 and the second wall 115a1 are both planes, and the processing is relatively simple. Of course, the first wall 341 and the second wall 115a1 are not limited to planes, and can also be curved surfaces, such as arc surfaces.

[0120] Please refer again Fig.12 In the embodiment of the present application, the middle frame further includes a second side, and the first side and the second side are located on both sides of the middle frame along the thickness direction S3 thereof. The through hole 115 is a through hole that penetrates the thickness of the middle frame, that is, the through hole 115 extends from the first side of the middle frame to the second side. The through hole 115 includes a first opening end 115b and a second opening end 115c, which are located on the first side and the second side, respectively. That is, the through hole 115 forms a first opening end 115b on the first side, and the through hole 115 forms a second opening end 115c on the second side. The recessed cavity 115a extends to the second opening end 115c, from Fig.12 As can be seen from the figure, the through hole is a stepped hole, and the through hole 115 includes a first hole section 1151 and a second hole section 1152 connected by a stepped surface, see Fig.12 , the first hole section 1151 and the second hole section 1152 are arranged and connected along the axial direction of the through hole 115. The hole section between the two dotted lines is the first hole section 1151. The recessed cavity 115a is a part of the space corresponding to the step surface of the second hole section 1152, that is, the second hole section includes the recessed cavity 115a. The step surface faces the second opening end 115c, and the step surface is the second wall 115a1.

[0121] In the embodiment of the present application, the section of the first middle frame 11 where the through hole 115 is provided has an inclined surface 116. Usually, the second side of the inclined surface 116 is inclined toward one side of the rotation axis, and the angle between the inclined surface 116 and the S3 direction can be determined according to the specific product. The extension direction of the through hole 115 is the same as the inclination direction of the inclined surface 116. This can maximize the thickness of the hole wall at the through hole 115, and make the second opening end of the through hole 115 on the second side as close as possible to the coverage range of the back cover, so as to avoid the opening of the through hole 115 affecting the appearance of the middle frame 1, and the design is simple. The hole wall extension line n of the through hole 115 does not intersect with the display screen 2, so as to avoid interference between the mounting body 34 and the display screen 2 during installation. Please combine Fig.11 and Fig.12 understand.

[0122] Since the mounting body 34 is mounted inside the through hole 115, when the through hole is inclined, the mounting body 34 also has an inclined section 343 adapted to the through hole 115. In a specific embodiment, the mounting body 34 also includes a vertical section 344, and the inclined section 343 is connected to the second surface 32 through the vertical section 344. Fig.11 understand.

[0123] Please refer to Fig.13 In the embodiment of the present application, the electronic device further includes an injection channel 115a0, which is formed between the mounting body 34 and the corresponding cavity wall 115a2 of the recessed cavity 115a, and one end of the injection channel 115a0 is connected to the accommodating space, and the other end is connected to the second opening end. In this way, the glue can flow into the accommodating space from between the mounting body 34 and the cavity wall 115a2 of the recessed cavity 115a, and form a block between the first wall 341 and the second wall 115a1. In this way, there is no need to set a channel for fluid material injection at other positions of the middle frame, which simplifies the processing technology of the middle frame 1 and helps to improve the use strength of the middle frame 1.

[0124] Please combine Figures 11 to 13In the embodiment of the present application, the mounting body 34 includes a first column section 34-1 and a second column section 34-2 connected to each other. The first column section 34-1 is circumferentially matched with the first hole section 1151. The second column section 34-2 is located in the second hole section 1152. The recessed portion 34a is located in the second column section 34-2. The recessed portion 34a and the recessed cavity 1152a of the second hole section 1152 are arranged relative to each other. Since the first column section 34-1 matches the first hole section 1151 in shape, the two are basically fitted or interposed in the circumferential direction. The gap is very small, so that the glue-containing cavity formed by the recessed portion 34a and the recessed cavity 1152a is located on one side of the first hole section 1151 and is basically a closed structure. The injected glue basically does not flow between the first hole section 1151 and the first column section 34-1, and the fluid material such as glue or plasticine entering from the second opening end will basically be between the recessed portion 34a and the recessed cavity 1152a, which is beneficial to improving the quality of the block curing molding, and further improving the reliability of the mounting body 34 and the through hole 115 snap-in.

[0125] Please refer to Fig.13 In the embodiment of the present application, the second surface 32 has a supporting area 321 supported on the frame 10, and the decorative member 3 also includes an extension section 315, which extends from the supporting area 321 toward one side of the display screen 2, and the corresponding side edge of the display screen 2 is located between the extension section 315 and the middle frame, that is, a space for the side edge of the display screen 2 to slide is formed between the extension section 315 and the middle frame 1.

[0126] In the embodiment of the present application, the frame 10 can provide a supporting base for the decorative element 3, and the decorative element 3 is easy to install.

[0127] Please refer to Fig.10 In the embodiment of the present application, the frame 10 can be slightly higher than the display screen 2, so that there can be a predetermined gap between the decorative element 3 and the display screen 2, and an elastic buffer pad 6 can be provided on the surface of the extension section 315 facing the display screen 2. The elastic buffer pad 6 can be a component such as silicone or rubber or film that plays a buffering and wear-resistant role, and the extension section 315 is in contact with the display screen 2 through the elastic buffer pad 6. In this way, the wear of the extension section 315 on the display screen 2 can be reduced, and the display screen 2 can be protected.

[0128] In the embodiment of the present application, an adhesive layer (not shown in the figure) may also be provided between the support area 321 and the frame 10. In this embodiment, the support area 321 of the decorative part 3 is further fixed to the middle frame through the adhesive layer, thereby improving the fixing reliability of the decorative part 3.

[0129] In order to maximize the bonding area between the decorative member 3 and the first middle frame 11, please refer to Fig.15The second surface 32 of the decorative element 3 also has a boss 36. The figure shows that the boss 36 includes two sections: a first boss 361 and a second boss 362. The height of the first boss 361 is greater than the height of the second boss 362, and the heights of the first boss 361 and the second boss 362 are both less than the height of the mounting body 34. Please refer to Fig.14 Correspondingly, the frame 10 is also provided with a groove 114. Specifically, the groove 114 also includes two sections: a first groove 1141 and a second groove 1142. The first boss 361 is inserted into the first groove 1141, and the second boss 362 is inserted into the second groove 1142. The first groove 1141 and the second groove 1142 are both filled with adhesive to bond and fix the corresponding bosses and grooves.

[0130] Of course, the form of the boss 36 is not limited to the above-mentioned arrangement of the first boss 361 and the second boss 362. The structure and form of the boss 36 can be determined according to the specific product.

[0131] As described above, the frame 10 includes side portions 101 and corner portions 102 connected between adjacent side portions 101. Fig.14 The frame body 10 on the first middle frame 11 includes three side portions, the first groove 1141 can be located at one of the side portions 101, the second groove 1142 is located at the corner portion 102, the first groove 1141 is located at the side portion 101, and the depth of the second groove 1142 is less than the depth of the first groove 1141 (see Fig.14 ), accordingly, the height of the first boss 361 is greater than the height of the second boss 362 (see Fig.15 ), the matching relationship between the first groove 1141 and the first boss 361 is shown in Fig.16 The matching relationship between the second groove 1142 and the second boss 362 is shown in Fig.10 .

[0132] Please combine Fig. 9 and Fig.15 It is understood that for the scenario where the decorative member 3 is located on both sides at the same time, the decorative member 3 includes a side segment 3-1 and a turning segment 3-2, the turning segment 3-2 is supported on the corner portion 102, and the side segment 3-1 is supported on the side portion 101. The side portion 101 and the side segment 3-1 can both be straight segments, and the turning segment 3-2 and the turning portion can be arc-shaped. Most of the second boss 362 is located in the turning segment 3-2. The figure shows the dividing line a and the dividing line b between the side segment 3-1 and the turning segment 3-2, and the mounting body is usually arranged on the side segment 3-1.

[0133] It is inevitable that electronic devices will accidentally fall during use. Since the corners of the electronic device have a smaller contact area with the ground when they fall, the impact force they receive is relatively large, and the probability of damage to the corners is relatively high. To this end, the present application also makes the following improvements to the structure of the electronic device.

[0134] Please refer to Fig.14 In the embodiment of the present application, the depth of the second groove 1142 near the corner 102 of the electronic device is shallower than that at other positions, so that the strength of the middle frame at the corner is relatively high, which is beneficial to improving the use strength of the corner of the electronic device and improving the force strength of the corner.

[0135] In the embodiment of the present application, the second groove 1142 can extend to the side portion 101, and the through hole 115 is opened in the second groove 1142 and is located at the side portion 101.
