Description

TECHNICAL FIELD

[0001] The present application relates to the field of foldable electronic products, in particular to a foldable electronic device. BACKGROUND

[0002] With the continuous development of flexible display screen technology, it is widely used in various foldable electronic devices. The foldable electronic device often includes a housing device for carrying a flexible display screen. The housing device generally includes two housings and a rotating shaft assembly connected between the two housings. The two housings are relatively folded or relatively unfolded by the movement of the rotating shaft assembly. In the traditional screen-in folding electronic device, when the electronic device is folded, the flexible display screen is folded on the inner side of the electronic device. At this time, the bending part of the flexible display screen is easy to be damaged due to being excessively pressed by the housing device. Therefore, the current screen-in folding electronic device usually sets a supporting steel sheet between the flexible display screen and the rotating shaft assembly to enhance the anti-pressing ability of the flexible display screen. However, the addition of the supporting steel sheet greatly increases the rebound force of the whole machine, affecting the opening and closing experience of the whole machine. SUMMARY

[0003] The embodiments of the present application provide a foldable electronic device, which aims to provide a foldable electronic device capable of enhancing the anti-pressing ability when the screen is folded, while the rebound force is small.

[0004] The present application provides a foldable electronic device. The electronic device includes a first middle frame, a second middle frame, a rotating shaft assembly, a screen and a support. The rotating shaft assembly connects the first middle frame and the second middle frame. The screen is fixedly connected to the first middle frame and the second middle frame. The support is located between the rotating shaft assembly and the screen. The support includes a main body part, a fixed part and a free part. The fixed part and the free part are connected to the two sides of the main body part, respectively. The fixed part is fixedly connected to the first middle frame. The free part is overlapped on the second middle frame and can move relative to the second middle frame. The support is also provided with a plurality of first holes and a plurality of second holes. The plurality of first holes are arranged at intervals along the length extension direction of the rotating shaft assembly. The plurality of second holes are arranged at intervals along the length extension direction of the rotating shaft assembly. The extension directions of the plurality of first holes and the plurality of second holes are all intersected with the length extension direction of the rotating shaft assembly. The electronic device has an open state and a closed state. When the electronic device is in the open state, the support is flat, and the plurality of first holes and the plurality of second holes are all flat. The overlapping part of the free part and the second middle frame in the first direction has a first length in the second direction. When the electronic device is in the closed state, the support is folded, and the plurality of first holes and the plurality of second holes are all folded along the second direction. The overlapping part of the free part and the second middle frame in the first direction has a second length in the second direction. The second length is smaller than the first length. The first direction is the thickness direction of the electronic device. The second direction is perpendicular to the first direction and the length extension direction of the rotating shaft assembly.

[0005] It can be understood that the electronic device in the embodiment can effectively enhance the extrusion resistance of the screen when the electronic device is bent by arranging the support between the screen and the hinge assembly, thereby facilitating the enhancement of the structural reliability of the screen and reducing the risk of damage to the screen when the screen is bent.

[0006] Secondly, the electronic device in the embodiment can effectively reduce the rebound force when the support is folded by arranging the first hole and the second hole intersecting with the length extension direction of the hinge assembly on the support, thereby avoiding the fracture of the support when the support is folded, facilitating the enhancement of the structural stability of the support and prolonging the service life of the support. At the same time, the first hole and the second hole can be bent along with the folding of the electronic device, thereby effectively avoiding the extrusion of the screen by the support due to the generation of a large rebound force when the support is folded, effectively avoiding the damage of the screen due to wrinkles, facilitating the prolongation of the service life of the screen, thereby prolonging the overall service life of the electronic device. At the same time, the rebound force of the entire electronic device when closed can also be effectively reduced, thereby improving the opening and closing experience of the entire electronic device and enhancing the user experience.

[0007] Secondly, the extension direction of the plurality of first holes and the plurality of second holes of the support in the embodiment can intersect with the length extension direction of the hinge assembly, that is, can intersect with the extension direction of the plurality of through holes of the bearing plate of the screen, thereby effectively avoiding the problem that the first hole and / or the second hole of the support and the through hole of the bearing plate are mutually hooked and interfered when the electronic device is converted between the open state and the closed state, causing the deformation of the support and / or the bearing plate, thereby prolonging the service life of the support, thereby prolonging the overall service life of the electronic device and improving the user experience.

[0008] In addition, compared with the electronic device in which both ends of the support are fixedly connected to the middle frame, in the embodiment, the support is fixed to the first middle frame at one end (i.e., the fixed part) and is overlapped on the second middle frame at the other end (i.e., the free part) and can move relative to the second middle frame. In this way, when the electronic device is in the closed state and the support is folded, the fixed part of the support does not move relative to the first middle frame or only moves slightly, and the free part of the support can move relative to the second middle frame along with the folding of the support, thereby effectively reducing the rebound force when the support is folded to avoid the extrusion of the screen by the support when the support is folded, avoid the damage of the screen due to wrinkles, facilitate the improvement of the overall service life of the electronic device, and also effectively reduce the rebound force of the entire electronic device when closed, thereby improving the opening and closing experience of the entire electronic device.

[0009] In addition, the support member can cover the area with weak structural strength and / or the area with a step difference of the hinge assembly in the first direction. In this way, the support member can not only protect the area with weak structural strength of the hinge assembly, but also provide a relatively flat support environment for the screen, so that the problem of unevenness of the screen caused by the step difference of the hinge assembly can be effectively avoided, and the light and shadow effect of the screen can be affected.

[0010] In a possible implementation, the hinge assembly includes a first support plate and a second support plate. The first support plate and the second support plate can be unfolded relative to each other or folded relative to each other. When the electronic device is in the open state, the first support plate and the second support plate are unfolded, and the main body portion is overlapped on the first support plate and the second support plate and can move relative to the first support plate and the second support plate. When the electronic device is in the closed state, the first support plate and the second support plate are folded, and the main body portion is bent and located between the first support plate and the second support plate. In this way, when the electronic device is in the closed state, the main body portion of the support member can be bent under the action of the first support plate and the second support plate to accommodate at least part of the screen, so that the curved screen can be better protected.

[0011] In a possible implementation, the plurality of first holes constitute a first through-hole group, and the plurality of second holes constitute a second through-hole group. The first through-hole group and the second through-hole group are arranged in a spaced manner. The second through-hole group is located between the first through-hole group and the free portion.

[0012] It can be understood that, in the electronic device in this embodiment, the second through-hole group is located between the first through-hole group and the free portion, and the first through-hole group and the second through-hole group are arranged in a spaced manner, so that the part of the support member between the first through-hole group and the second through-hole group can also shield the area with weak structural strength and / or the area with a step difference of the hinge assembly. In this way, the support member can not only protect the area with weak structural strength of the hinge assembly, but also provide a relatively flat support environment for the screen, so that the problem of unevenness of the screen caused by the step difference of the hinge assembly can be effectively avoided, and the light and shadow effect of the screen can be affected.

[0013] In a possible implementation, when the electronic device is in the open state, the plurality of first holes all expose part of the first support plate, and the plurality of second holes all expose part of the second support plate. In this way, the plurality of first holes and the plurality of second holes can all be located on the main body portion of the support member, that is, on the part with a relatively large rebound force when the support member is bent, so that the rebound force of the support member when it is bent can be greatly reduced, to avoid the main body portion from pressing the screen when it is bent, to effectively avoid the screen from being damaged due to wrinkles, and to be beneficial to further prolong the service life of the screen, thereby prolonging the overall service life of the electronic device. At the same time, the rebound force of the electronic device when the whole machine is closed can be further reduced, which is beneficial to further improve the opening and closing experience of the whole machine of the electronic device, to improve the user experience.

[0014] In a possible implementation, when the electronic device is in the open state, the at least part of the first holes expose the part of the first support plate and the part of the first middle frame.

[0015] It can be understood that the support in the embodiment also prolongs the length of the part of the first holes and the part of the second holes, so that the part of the first holes can simultaneously expose the part of the first support and the part of the first middle frame, and the part of the second holes can simultaneously expose the part of the second support and the part of the second middle frame, regardless of whether the electronic device is in the open state or the closed state. In this way, the part of the first holes can expose the gap between the part of the first support plate and the first middle frame, and the part of the second holes can expose the gap between the part of the second support plate and the second middle frame, regardless of whether the electronic device is in the open state or the closed state, so that when the support is converted between unfolding and folding, the force borne by the support at different gaps can be smoothly transitioned through the part of the longer first holes and the part of the longer second holes respectively, thereby effectively avoiding the support from being broken at different gaps due to a larger force, and being beneficial to enhancing the structural stability of the support to prolong the service life of the support, thereby prolonging the overall service life of the electronic device.

[0016] In a possible implementation, the support has a shielding area. The shielding area is located between the first hole group and the second hole group. When the electronic device is in the open state, a gap is formed between the first support plate and the second support plate, and the shielding area covers at least part of the gap in the first direction.

[0017] It can be understood that the electronic device in the embodiment avoids the area above the gap (that is, the gap between the first support plate and the second support plate) of the hinge assembly by spacing the first hole group and the second hole group, thereby forming a shielding area between the first hole group and the second hole group, so that the support can have the shielding area covering the gap in the first direction while the plurality of first holes and the plurality of second holes are provided to reduce the rebound force of the support, thereby effectively avoiding the screen from being broken at the gap of the hinge assembly when the screen is unfolded, and being beneficial to improving the light and shadow at the gap of the hinge assembly when the screen is unfolded.

[0018] In a possible implementation, when the electronic device is in the open state, the gap is symmetrically arranged about the first axis, and the first hole group and the second hole group are symmetrically arranged about the second axis. The projection of the second axis on the support is located between the projection of the first axis on the support and the free part.

[0019] It can be understood that, in the electronic device in this embodiment, the second axis of the shielding area is arranged between the first axis of the gap and the free part, that is, the shielding area can be arranged asymmetrically about the first axis, and at this time, the shielding area can reserve a play range. In this way, when the electronic device is in the open state, the shielding area can cover the gap in the first direction. When the electronic device is converted between the open state and the closed state, the play range reserved by the shielding area enables the shielding area to not be hooked with the first support plate when the relative pivot assembly is played, so that the problem of deformation of the support member due to being hooked with other components can be effectively avoided, the service life of the support member is beneficially prolonged, and the service life of the entire electronic device is thus prolonged.

[0020] In a possible implementation, the support member is provided with a third hole group and a fourth hole group. The third hole group and the fourth hole group are respectively located on different sides of the shielding area. The third hole group includes a plurality of third holes, and the plurality of third holes respectively expose part of the first support plate. The fourth hole group includes a plurality of fourth holes, and the plurality of fourth holes respectively expose part of the second support plate. The screen is fixedly connected to the pivot assembly through at least one third hole and at least one fourth hole.

[0021] It can be understood that, in the electronic device in this embodiment, the third holes and the fourth holes are arranged on the support member to respectively expose part of the first support plate and part of the second support plate, so that the screen can be fixedly connected to the first support plate and the second support plate of the pivot assembly through the third holes and the fourth holes, thereby effectively increasing the fixing area between the screen and the pivot assembly, reducing the influence of the support member on the fixation of the screen, and being beneficial to improving the connection stability between the screen and the housing device.

[0022] In a possible implementation, the electronic device further includes a plurality of first adhesive layers and a plurality of second adhesive layers. The plurality of first adhesive layers are one-to-one correspondingly located in the plurality of third holes and are connected between the first support plate and the screen. The plurality of second adhesive layers are one-to-one correspondingly located in the plurality of fourth holes and are connected between the second support plate and the screen. The third hole includes a first edge, and the first edge is close to the shielding area. The fourth hole includes a second edge, and the second edge is away from the shielding area. When the electronic device is in the open state, the distance between the first adhesive layer and the first edge in the second direction is a first width. The distance between the second adhesive layer and the second edge in the second direction is a second width. The second width is greater than the first width. The first width is greater than 0.

[0023] It can be understood that the electronic device in this embodiment can reserve a part of space in the third hole to form a dislocation space (i.e. the space between the first glue layer and the first edge) by spacing the first glue layer from the first edge of the corresponding third hole, and reserve a part of space in the fourth hole to form a dislocation space (i.e. the space between the second glue layer and the second edge) by spacing the second glue layer from the second edge of the corresponding fourth hole. In this way, when the electronic device is switched from the open state to the closed state, the free part can move relative to the second middle frame in the direction of approaching the main part, and the third hole and the fourth hole also move relative to the shaft assembly. Among them, the first edge of the third hole gradually approaches the first glue layer. The second edge of the fourth hole gradually approaches the second glue layer. Because the third hole and the fourth hole both reserve dislocation spaces, even if the third hole moves relative to the shaft assembly, it will not interfere with the first glue layer, and even if the fourth hole moves relative to the shaft assembly, it will not interfere with the second glue layer. In other words, in this embodiment, whether the electronic device is in an open state or a closed state, the first glue layer and the second glue layer will not interfere with the support, so that the screen can be stably fixed with the shaft assembly whether the electronic device is in an open state or a closed state, which is beneficial to improve the fixing stability of the screen.

[0024] Secondly, the third hole group in this embodiment is located between the free part and the fourth hole group, that is, the third hole group is closer to the free part than the fourth hole group. When the electronic device is in a closed state, the distance that the third hole moves relative to the shaft assembly will be greater than the distance that the fourth hole moves relative to the shaft assembly. In this embodiment, the width of the distance between the first edge of the third hole corresponding to the first glue layer in the second direction (i.e. the first width) can be less than the width of the distance between the second edge of the fourth hole corresponding to the second glue layer in the second direction (i.e. the second width). In this way, by setting the first width to be less than the second width, the third hole can not interfere with the first glue layer when the electronic device is in a closed state, and the fourth hole can not interfere with the second glue layer at the same time, so that the screen can be stably fixed with the shaft assembly whether the electronic device is in an open state or a closed state, which is beneficial to further improve the fixing stability of the screen.

[0025] In a possible implementation, the first edge of the third hole is curved. In this way, by curving the edge of the third hole close to the shielding area (i.e. the first edge), when the support is folded, the curved first edge can better uniformly release the stress at this position, so that the problem that the part of the support at the first edge is lifted in the direction towards the outside of the electronic device and interferes with the first support plate, causing the support to deform, can be effectively avoided, which is beneficial to prolong the service life of the support.

[0026] In a possible implementation, the fourth hole further includes a fourth edge. The fourth edge is close to the shielding area. The fourth edge is curved. In this way, by curving the edge of the fourth hole close to the shielding area (i.e., the fourth edge), when the support is folded, the curved fourth edge can better uniformly release the stress at this position, thereby effectively avoiding the problem that the part of the support at the fourth edge is warped in the direction towards the outside of the electronic device and interferes with the second support plate, causing the support to be deformed, and facilitating prolonging the service life of the support.

[0027] In a possible implementation, the first support plate and the first middle frame form a first gap therebetween. The second support plate and the second middle frame form a second gap therebetween. When the electronic device is in the open state, the main body part covers at least part of the first gap and at least part of the second gap in the first direction. In this way, the support can cover the gaps of the hinge assembly in the first direction, and also cover at least part of the first gap and at least part of the second gap, thereby avoiding the problem that the screen is broken at the above positions when the screen is flattened, and facilitating improving the light and shadow of the screen.

[0028] In a possible implementation, when the electronic device is in the closed state, the main body part covers at least part of the first gap in the first direction, and the free part covers at least part of the second gap in the first direction. In this way, even if the electronic device is folded and the free part of the support moves, the support can still cover at least part of the first gap and at least part of the second gap in the first direction, thereby effectively avoiding the problem that the screen is broken at the above positions when the screen is folded, so that the support can better protect the screen and prolong the service life of the screen.

[0029] In a possible implementation, the electronic device further includes a first heat dissipation member. The first heat dissipation member includes a main body part and an extension part connected to each other. The main body part is fixedly connected to the first middle frame. The extension part overlaps the second middle frame and is movable relative to the second middle frame. The fixed part of the support is fixedly connected to the main body part, or a part of the fixed part is fixedly connected to the first middle frame and a part of the fixed part overlaps the main body part. At least part of the free part of the support overlaps the extension part and is movable relative to the extension part.

[0030] It can be understood that, in the embodiment, the main body part of the first heat dissipation member is fixed to the first middle frame, and the extension part of the first heat dissipation member spans the hinge assembly and is fixedly connected to the second middle frame, so that part of the heat of the first middle frame can be directly dissipated through the first heat dissipation member, and another part of the heat can be transmitted to the second middle frame through the first heat dissipation member, so that the second middle frame can assist the first middle frame in dissipating heat, and the heat dissipation efficiency of the electronic device is improved.

[0031] In a possible implementation, the support member covers the extended portion of the first heat dissipation member in the first direction. In this way, the support member can help the first heat dissipation member to smoothly cross the rotating shaft assembly, so that the first heat dissipation member can be kept in contact with the second middle frame under the action of the support member, and heat transfer is achieved. Meanwhile, the support member covering the extended portion of the first heat dissipation member can effectively avoid the extended portion from being wrinkled due to bending, and affect the light and shadow effect of the screen.

[0032] In a possible implementation, the material of the first heat dissipation member is graphite. In this way, the first heat dissipation member has a relatively high heat dissipation efficiency.

[0033] In a possible implementation, the electronic device further includes a second heat dissipation member. The second heat dissipation member is fixedly connected to the second middle frame. When the electronic device is in the open state and the closed state, the extended portion of the first heat dissipation member overlaps the second heat dissipation member and can move relative to the second heat dissipation member.

[0034] It can be understood that, in the embodiment, the electronic device is provided with the second heat dissipation member fixedly connected to the second middle frame, and the extended portion of the first heat dissipation member overlaps the second heat dissipation member and can move relative to the second heat dissipation member. In this way, part of the heat of the first middle frame can be dissipated through the first heat dissipation member, and another part of the heat can be conducted to the second heat dissipation member through the first heat dissipation member, and dissipated through the second heat dissipation member, thereby effectively improving the overall heat dissipation efficiency of the electronic device.

[0035] In a possible implementation, the electronic device further includes a first lubricating member. The first lubricating member is fixedly connected to the extended portion and located between the extended portion and the second middle frame. In this way, by arranging the first lubricating member between the extended portion of the first heat dissipation member and the second middle frame, when the electronic device is converted between the open state and the closed state, the first lubricating member can reduce the friction between the extended portion of the first heat dissipation member and the second middle frame, so that the support member and the first heat dissipation member can relatively smoothly dislocate relative to the second middle frame, so that the opening and closing of the electronic device is more smooth, and the user experience is improved.

[0036] In a possible implementation, the electronic device further includes a second lubricating member. The second lubricating member is fixedly connected to the support member and located between the support member and the screen. In this way, by arranging the second lubricating member between the support member and the screen, when the electronic device is converted between the open state and the closed state, the second lubricating member can reduce the friction between the screen and the support member, so that the support member can relatively smoothly dislocate relative to the screen, so that the opening and closing of the electronic device is more smooth, and the user experience is improved. In addition, the second lubricating member can also isolate the screen and the support member, so that the screen and the support member are insulated, thereby effectively avoiding the problem of radiation interference between the screen and the support member.

[0074] Figure 1 is a structural schematic diagram of an electronic device 1000 in an open state according to an embodiment of the present application. Figure 2 is a structural schematic diagram of an electronic device 1000 in a closed state according to an embodiment of the present application. Figure 1 is a structural schematic diagram of an electronic device 1000 in a closed state according to an embodiment of the present application.

[0075] As shown in Figure 1 and Figure 2 , the electronic device 1000 can include a housing device 100 and a screen 200. The screen 200 can be mounted to the housing device 100. The housing device 100 can be in an open state as shown in Figure 1 , and in a closed state as shown in Figure 2The housing device 100 can also be in an intermediate state between unfolded and folded. The intermediate state can be any state between the unfolded state and the folded state. The screen 200 can move with the housing device 100. The housing device 100 can drive the screen 200 to unfold or fold, so that the electronic device 1000 can be unfolded to the unfolded state or folded to the folded state. When the electronic device 1000 is in the folded state, the screen 200 can be located inside the housing device 100. In other words, the electronic device 1000 can be a screen-in folding electronic device. For ease of understanding, the surface of the housing device 100 opposite to the screen 200 of the electronic device 1000 is defined as a reference surface, and the direction perpendicular to the reference surface is defined as the thickness direction of the electronic device 1000, i.e., the first direction. The thickness direction of the electronic device 1000 is defined as the Z-axis direction, the length direction of the electronic device 1000 (i.e., the second direction) is defined as the X-axis direction, and the width direction of the electronic device 1000 (i.e., the third direction) is defined as the Y-axis direction. The direction same as the light-out direction of the screen 200 is defined as "up", and the direction opposite to the light-out direction of the screen 200 is defined as "down". In other embodiments, the coordinate axes can also be established according to actual needs. For example, the width direction of the electronic device 1000 is defined as the X-axis direction, and the length direction of the electronic device 1000 is defined as the Y-axis direction.

[0076] In the embodiment, when the electronic device 1000 is in the unfolded state, the screen 200 can be unfolded. At this time, the screen 200 can perform full-screen display, and the electronic device 1000 has a large display area, which is beneficial to improve the viewing experience and operation experience of the user. When the electronic device 1000 is in the folded state, the planar size of the electronic device 1000 is small, which is convenient for the user to carry and store.

[0077] Exemplarily, the housing device 100 can include a first housing 10, a second housing 20, and a hinge assembly 30. The hinge assembly 30 can be connected between the first housing 10 and the second housing 20. The hinge assembly 30 can move to enable the first housing 10 and the second housing 20 to be relatively unfolded to the unfolded state or relatively folded to the folded state.

[0078] Exemplarily, the screen 200 can integrate a display function and a touch sensing function. The display function of the screen 200 is used to display images, videos, etc., and the touch sensing function of the screen 200 is used to sense the touch action of the user to realize human-computer interaction. Exemplarily, the screen 200 includes a flexible display screen that can be bent. The flexible display screen can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, an active-matrix organic light emitting diode (AMOLED) display screen, a flexible light-emitting diode (FLED) display screen, a MiniLED display screen, a MicroLED display screen, a Micro-OLED display screen, a quantum dot light emitting diodes (QLED) display screen, etc.

[0079] Exemplarily, the electronic device 1000 can further include a plurality of components (not shown in the figure) installed inside the housing device 100. The plurality of components can include, for example, a processor, an internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, an earphone interface, a sensor module, a key, a motor, an indicator, and a subscriber identification module (SIM) card interface, etc.

[0080] It should be understood that in the present embodiment, the electronic device 1000 is taken as an example of a two-fold structure, i.e., the electronic device 1000 includes two flat plate portions and a bending portion connected between the two flat plate portions. The two flat plate portions can be rotated towards each other to be stacked on each other (corresponding to the closed state described above), so that the electronic device 1000 presents a two-layered form; the two flat plate portions can also be rotated away from each other to be flat (corresponding to the open state described above).

[0081] In other embodiments, the electronic device 1000 may also have a structure that folds three or more times, that is, the electronic device 1000 may include three or more flat panels, with adjacent panels connected by a bent portion. The adjacent panels can be rotated relative to each other to overlap or rotated away from each other to flatten. When the electronic device 1000 has a structure that folds three or more times, the structure of the electronic device 1000 can be adaptively designed by referring to the description of the two-fold structure in this embodiment, and this application will not elaborate on this further.

[0082] Figure 3 yes Figure 1 The schematic diagram shows a partial structure of the housing device 100 of the electronic device 1000 when it is in an open state. Figure 4 yes Figure 3 The illustrated schematic diagram is an exploded structural diagram of the housing device 100 in some embodiments.

[0083] like Figures 2-4 As shown, the first housing 10 may include a first middle frame 11, a first back cover 12, and a first decorative member 13. The first middle frame 11 may be located on one side of the hinge assembly 30 and connected to the hinge assembly 30. The first back cover 12 may be located below the first middle frame 11 and fixedly connected to the first middle frame 11. The first decorative member 13 may be fixedly connected to the periphery of the first middle frame 11 and the periphery of the first back cover 12. In this case, the first back cover 12 and the first decorative member 13 may both form part of the exterior of the electronic device 1000.

[0084] Exemplarily, the first middle frame 11 may include a first frame portion 111, a first middle plate portion 112 and a first extension portion 113. The first middle plate portion 112 may be located on the inner side of the first frame portion 111. The first extension portion 113 may be fixedly connected to the first middle plate portion 112. The first extension portion 113 and the first middle plate portion 112 may have a height difference in the first direction Z. At this time, the first extension portion 113 may form a first mounting groove 114 with the first frame portion 111. Exemplarily, the first middle plate portion 112 may be provided with a plurality of mounting structures such as protrusions and grooves for cooperating with other components of the electronic device 1000, so that other parts can be installed on the first middle frame 11.

[0085] Exemplarily, the first back cover 12 may be a protective cover plate for protecting the components inside the first shell 10 and also for presenting part of the appearance of the electronic device 1000. The first decorative member 13 may be provided with a plurality of communication holes. The plurality of communication holes may be used to enable the plurality of components installed in the shell device 100 to interact with the external environment of the electronic device 1000. The plurality of communication holes may include, but are not limited to: a USB jack corresponding to a USB interface, a camera hole corresponding to a camera, a speaker hole corresponding to a speaker, a receiver hole corresponding to a receiver, a microphone hole corresponding to a microphone, a headphone jack corresponding to a headphone interface, a button hole corresponding to a button, an indicator light hole corresponding to an indicator, and a SIM card jack corresponding to a SIM card interface.

[0086] In other embodiments, the first housing 10 may not include the first decorative member 13. In this case, the outer edge of the first frame portion 111 of the first middle frame 11 may form a part of the exterior of the electronic device 1000.

[0087] like Figures 2-4 As shown, the second housing 20 may include a second middle frame 21, a second back cover 22, and a second decorative member 23. The second middle frame 21 may be located on a side of the hinge assembly 30 away from the first middle frame 11 and connected to the hinge assembly 30. The second back cover 22 may be located below the second middle frame 21 and fixedly connected to the second middle frame 21. The second decorative member 23 may be fixedly connected to the periphery of the second middle frame 21 and the periphery of the second back cover 22. In this case, the second back cover 22 and the second decorative member 23 may form part of the exterior of the electronic device 1000.

[0088] Exemplarily, the second middle frame 21 may include a second frame portion 211, a second middle plate portion 212 and a second extension portion 213. The second middle plate portion 212 may be located on the inner side of the second frame portion 211. The second extension portion 213 may be fixedly connected to the second frame portion 211. The second extension portion 213 and the second middle plate portion 212 may have a height difference in the first direction Z. At this time, the second extension portion 213 may form a second mounting groove 214 with the second frame portion 211. Exemplarily, the second middle plate portion 212 may be provided with a plurality of mounting structures such as protrusions and grooves for cooperating with other components of the electronic device 1000, so that other parts can be installed on the second middle frame 21.

[0089] Exemplarily, the second back cover 22 can be a protective cover plate for protecting devices inside the second housing 20, and also for presenting part of the appearance of the electronic device 1000. The second decorative piece 23 can be provided with a plurality of communication holes. The plurality of communication holes can be used to enable a plurality of components installed in the housing device 100 to interact with the external environment of the electronic device 1000. The specific arrangement of the communication holes of the second decorative piece 23 can refer to the communication holes of the first decorative piece 13, which will not be described here.

[0090] In other embodiments, the second housing 20 can also not include the second decorative piece 23. At this time, the outer edge of the second frame portion 211 of the second middle frame 21 can form part of the appearance piece of the electronic device 1000.

[0091] In some other embodiments, the first middle frame 11, the first back cover 12, and the first decorative piece 13 can also be an integrally formed structure, and the second middle frame 21, the second back cover 22, and the second decorative piece 23 can also be integrally formed. At this time, the electronic device 1000 can be an appearance-integrated electronic device.

[0092] It can be understood that the first housing 10 and the second housing 20 are both housing pieces for installing and fixing other components of the electronic device 1000, and have diversified structures. The first middle frame 11 of the first housing 10 and the second middle frame 21 of the second housing 20 are mainly shown in the subsequent drawings of the embodiments of the present application, and other structures in the first housing 10 and the second housing 20 are only briefly described. The embodiments of the present application do not strictly limit the specific structures of the first housing 10 and the second housing 20.

[0093] Figure 5 is Figure 4 is a structural schematic view of the hinge assembly 30 of the housing device 100 shown in the open state.

[0094] As Figure 5 shown, the hinge assembly 30 can include a main shaft portion 31, a back plate 32, a first support plate 33, and a second support plate 34. The main shaft portion 31 can be installed on the back plate 32. The surface of the back plate 32 facing away from the main shaft portion 31 can constitute part of the appearance surface of the electronic device 1000. The main shaft portion 31 can constitute the main movement mechanism of the hinge assembly 30. Exemplarily, the hinge assembly 30 can include a first end portion 30a and a second end portion 30b arranged in the third direction Y. The portion of the hinge assembly 30 between the first end portion 30a and the second end portion 30b is the middle portion 30c of the hinge assembly 30.

[0095] Exemplarily, the first support plate 33 and the second support plate 34 can be substantially symmetrical structures. The first support plate 33 and the second support plate 34 can each be a long strip-shaped plate body. The first support plate 33 can be connected to the main shaft portion 31. The second support plate 34 can be connected to the main shaft portion 31. The first support plate 33 and the second support plate 34 can move relative to the main shaft portion 31 to realize the relative unfolding and relative folding actions. Wherein, the first support plate 33 and the second support plate 34 can be symmetrically arranged about the first axis T1. It should be understood that, Figure 5 The first axis T1 is schematically shown by a dotted line in the figure. The first axis T1 is also schematically shown by a dotted line in subsequent figures as required.

[0096] Exemplarily, when the electronic device 1000 is in the open state, the first support plate 33 and the second support plate 34 can be relatively unfolded, and the first support plate 33 and the second support plate 34 can jointly provide a flat support environment. A gap 35 can be formed between the first support plate 33 and the second support plate 34. Wherein, the widths of the parts of the gap 35 in the second direction X can not be completely the same. For example, the width of the part of the gap 35 located at the first end portion 30a and / or the second end portion 30b of the pivot assembly 30 can be wider. The width of the part of the gap 35 located at the middle portion 30c of the pivot assembly 30 can be narrower. In this way, the first support plate 33 and the second support plate 34 can change the length of the gap 35 at different positions according to the specific structure of the pivot assembly 30, so as to better shield the structural recessed area of the main shaft portion 31, while avoiding the part of the main shaft portion 31 that rotates, so as to reduce the influence on the rotation of the main shaft portion 31.

[0097] Exemplarily, the gap 35 can be symmetrically arranged about the first axis T1. Wherein, the symmetrical arrangement can be complete symmetrical arrangement, or can be approximate symmetrical arrangement. For example, the part of the gap 35 located at the middle portion 30c can be symmetrically arranged about the first axis T1. The part of the gap 35 located at the first end portion 30a and / or the second end portion 30b can be asymmetrically arranged about the first axis T1. At this time, the gap 35 can be regarded as being approximately symmetrically arranged about the first axis T1.

[0098] In other embodiments, the widths of the parts of the gap 35 in the second direction X can also be the same, that is, the parts of the gap 35 are equal in width. The specific shape of the gap 35 is not limited in the present application.

[0099] Figure 6 is a structural schematic view of the first middle frame 11, the second middle frame 21 and the pivot assembly 30 after being assembled and in the open state. Figure 4 is a structural schematic view of the structure in the closed state. Figure 7 Figure 6

[0100] ​​As shown in Figure 6 and Figure 7 part of the main shaft portion 31 can be located in the first mounting slot 114 of the first middle frame 11 and fixedly connected to the first extended portion 113 of the first middle frame 11. A part of the main shaft portion 31 can be located in the second mounting slot 214 of the second middle frame 21 and fixedly connected to the second extended portion 213 of the second middle frame 21. The first middle frame 11 and the second middle frame 21 can move with the main shaft portion 31 to relatively unfold to the open state or relatively fold to the closed state. At this time, the first gap 36 can be formed between the first support plate 33 and the first middle frame 11. The second gap 37 can be formed between the second support plate 34 and the second middle frame 21.

[0101] When the electronic device 1000 is in the open state, the first middle frame 11, the second middle frame 21, the first support plate 33, and the second support plate 34 can collectively provide a flat support environment. The first mounting slot 114 of the first middle frame 11 and the second mounting slot 214 of the second middle frame 21 can collectively form a receiving space 100a to accommodate the entire shaft assembly 30. The first extended portion 113 of the first middle frame 11 and the second extended portion 213 of the second middle frame 21 can collectively shield the back plate 32 of the shaft assembly 30. That is, the back plate 32 of the shaft assembly 30 can be located inside the housing device 100. At this time, the first middle frame 11 and the second middle frame 21 can shield the internal structure such as the shaft assembly 30 from the bottom of the housing device 100.

[0102] When the electronic device 1000 is in the closed state, the first middle frame 11 and the second middle frame 21 can be relatively folded. The first support plate 33 and the second support plate 34 can be relatively folded. The first support plate 33 and the second support plate 34 can be located on the side of the main shaft portion 31 opposite to the back plate 32. The distance between the first support plate 33 and the second support plate 34 can increase in the direction close to the back plate 32. The main shaft portion 31, the first support plate 33, and the second support plate 34 can collectively form a screen containing space 38. At this time, the shape of the screen containing space 38 can present a water drop shape or a similar water drop shape. The back plate 32 of the shaft assembly 30 can be exposed relative to the first extended portion 113 of the first middle frame 11 and the second extended portion 213 of the second middle frame 21, and the appearance surface of the back plate 32 is exposed. At this time, the first middle frame 11, the second middle frame 21, and the back plate 32 can collectively shield other structures of the shaft assembly 30 and other internal structures of the electronic device 1000. In this way, the electronic device 1000 of the present embodiment can achieve self-shielding whether in the open state or in the closed state, and the appearance experience of the electronic device 1000 is better, and the waterproof and dustproof performance is better.

[0103] Please refer again to Figure 3 and Figure 4The housing device 100 may further include a first heat sink 40, a second heat sink 50, a support member 60, a first lubricating member 70, and a second lubricating member 80. When the electronic device 1000 is in an open state, the housing device 100, the screen 200, and the various components of the housing device 100 are correspondingly in an open state; when the electronic device 1000 is in a closed state, the housing device 100, the screen 200, and the various components of the housing device 100 are correspondingly in a closed state. In other embodiments, the housing device 100 may also not include the first heat sink 40, the second heat sink 50, the first lubricating member 70, and the second lubricating member 80.

[0104] The structures and positional relationships of the first heat dissipating member 40 , the second heat dissipating member 50 , the supporting member 60 , the first lubricating member 70 and the second lubricating member 80 of the housing device 100 will be described in detail below with reference to the relevant drawings.

[0105] Figure 8 yes Figure 4 FIG. 1 is a schematic structural diagram of the first heat dissipation element 40 of the housing device 100 . Figure 9 yes Figure 4 FIG. 1 is a partial structural diagram of the housing device 100 shown in FIG.

[0106] like Figure 8 and Figure 9 As shown, the material of the first heat sink 40 can be graphite or other materials with good heat dissipation performance. The first heat sink 40 can be a sheet structure. The first heat sink 40 can include a main body portion 41 and an extension portion 42 connected. It should be understood that Figure 8 The main portion 41 and the extending portion 42 of the first heat dissipating element 40 are schematically divided by dotted lines.

[0107] The main body part 41 of the first heat dissipation member 40 can be located above the first middle frame 11 and fixedly connected to the first middle frame 11 by adhesion or the like. The extension part 42 of the first heat dissipation member 40 can span the rotation shaft assembly 30 and extend to above the second middle frame 21. At this time, the extension part 42 can be lapped on the second middle frame 21 and movable relative to the second middle frame 21. Exemplarily, the shape of the main body part 41 of the first heat dissipation member 40 can be substantially the same as the shape of the upper surface of the first middle frame 11. In this way, the contact area between the main body part 41 of the first heat dissipation member 40 and the first middle frame 11 is large, so that the heat dissipation capacity of the first heat dissipation member 40 for the components mounted on the first middle frame 11 can be improved. The first middle frame 11 can be used to mount the components with large power (for example, chips, camera modules, etc.) in the electronic device 1000. In some embodiments, when the material of the first heat dissipation member 40 is graphite, the first heat dissipation member 40 can be attached to a sheet-shaped structural member. At this time, the first heat dissipation member 40 is a graphite layer. The sheet-shaped structural member can assist the first heat dissipation member 40 to be fixed to the first middle frame 11.

[0108] It can be understood that the first middle frame 11 in the embodiment can be used to mount the components with large power in the electronic device 1000. In this way, by arranging the main body part 41 of the first heat dissipation member 40 to be fixed to the first middle frame 11, the extension part 42 of the first heat dissipation member 40 to span the rotation shaft assembly 30 and fixedly connected to the second middle frame 21, part of the heat of the first middle frame 11 can be directly dissipated through the first heat dissipation member 40, and another part of the heat of the first middle frame 11 can also be transmitted to the second middle frame 21 through the first heat dissipation member 40, so that the second middle frame 21 can also assist the first middle frame 11 to dissipate heat, which is conducive to improving the heat dissipation efficiency of the electronic device 1000.

[0109] In some embodiments, the main body part 41 of the first heat dissipation member 40 can be provided with a first avoiding hole 411. The first avoiding hole 411 can expose the upper surface of the first middle frame 11. The first avoiding hole 411 can avoid the adhesive layer for fixing the first middle frame 11 and the screen 200. In this way, the adhesive layer fixed to the first middle frame 11 overlaps with the first heat dissipation member 40 in the first direction Z, and the first heat dissipation member 40 can better transmit heat to the second heat dissipation member 50, which is conducive to improving the heat dissipation capacity of the electronic device 1000. At the same time, the adhesive layer can also utilize the thickness space of the first heat dissipation member 40, so that the height difference between the adhesive layer and the first heat dissipation member 40 in the first direction Z can be reduced, which is conducive to improving the flatness of the screen 200 of the electronic device 1000 and improving the light and shadow effect of the screen 200.

[0110] Figure 10 is Figure 4 a partial structural schematic diagram of the shell device 100 shown in FIG. 1.

[0111] AsFigure 9 and Figure 10 As shown, the material of the second heat sink 50 can be graphite or other materials with good heat dissipation performance. The second heat sink 50 can be a sheet structure. Figure 4 The specific shape of the second heat sink 50 is also shown. The second heat sink 50 can be fixedly connected to the upper surface of the second middle frame 21 by bonding or other means. In this case, the extended portion 42 of the first heat sink 40 can overlap the surface of the second heat sink 50 facing away from the second middle frame 21.

[0112] It will be appreciated that the electronic device 1000 in this embodiment is fixedly connected to the second middle frame 21 by providing the second heat sink 50, and the extended portion 42 of the first heat sink 40 is overlapped with the second heat sink 50 and is movable relative to the second heat sink 50. In this way, part of the heat from the components mounted on the first middle frame 11 can be dissipated through the first heat sink 40, while the remaining heat can be conducted through the first heat sink 40 to the second heat sink 50 and dissipated through the second heat sink 50, effectively improving the overall heat dissipation efficiency of the electronic device 1000.

[0113] In some embodiments, a portion of the upper surface of the second middle frame 21 may be sunken to form an escape space 215. At this time, the portion of the second heat sink 50 located in the escape space 215 is correspondingly sunken to form a recess 51 ( Figure 4 The recess 51 is also shown. At least a portion of the extension 42 of the first heat sink 40 can be accommodated within the recess 51 of the second heat sink 50. This allows the extension 42 of the first heat sink 40 and the second heat sink 50 to overlap in the first direction Z. The extension 42 of the first heat sink 40 can utilize the thickness of the second heat sink 50, thereby reducing the height difference between the extension 42 of the first heat sink 40 and the second heat sink 50 in the first direction Z. This helps improve the flatness of the screen 200 and enhances the lighting effects of the screen 200.

[0114] Figure 11 yes Figure 4 FIG. 1 is a schematic structural diagram of the support member 60 of the housing device 100 . Figure 12 yes Figure 3 The shown schematic diagram is a partial structural diagram of the housing device 100 in an open state from another perspective.

[0115] like Figure 11 and Figure 12 As shown, the support member 60 can be made of a material with a certain strength and hardness and can be bent under external force. For example, the support member 60 can be a steel sheet. Of course, if the support performance requirements are met, the support member 60 can also be a metal sheet such as an aluminum sheet or a stainless steel sheet, or a non-metallic sheet. This application does not impose strict restrictions on this.

[0116] Exemplarily, the support member 60 may include a fixed portion 61, a main portion 62, and a free portion 63. The fixed portion 61 and the free portion 63 may be connected to both sides of the main portion 62, respectively. The fixed portion 61 may be located above the main portion 41 of the first heat sink 40 and fixedly connected to the main portion 41. The main portion 62 may be located above the shaft assembly 30. At least a portion of the free portion 63 may overlap the extension portion 42 of the first heat sink 40 and may be movable relative to the extension portion 42. It should be understood that Figure 11 and Figure 12 In the figure, the fixed portion 61, the main portion 62 and the free portion 63 of the support member 60 are schematically divided by dotted lines.

[0117] Exemplarily, the main portion 62 and the free portion 63 of the support member 60 can cover the extended portion 42 of the first heat sink 40 in the first direction Z. In this way, the support member 60 can help the first heat sink 40 to smoothly cross the shaft assembly 30, so that the first heat sink 40 can maintain contact with the second heat sink 50 under the action of the support member 60, thereby achieving heat transfer. At the same time, the support member 60 covering the extended portion 42 of the first heat sink 40 can also effectively prevent the extended portion 42 from generating a step difference due to bending and wrinkling, affecting the light and shadow effect of the screen 200. In some embodiments, when the material of the first heat sink 40 is graphite, the first heat sink 40 can be attached to a sheet structure as a graphite layer. At this time, the fixing portion 61 of the support member 60 can be fixed to the surface of the sheet structure facing away from the first heat sink 40.

[0118] In some embodiments, a portion of the fixing portion 61 may be fixedly connected to the first middle frame 11 , and a portion may be overlapped with the main body 41 .

[0119] In some embodiments, the main body 41 of the first heat sink 40 may be provided with an avoidance groove 412. The fixed portion 61 of the support member 60 may be accommodated in the avoidance groove 412 of the first heat sink 40. The free portion 63 of the support member 60 may be accommodated in the recess 51 of the second heat sink 50. In this way, there are overlapping portions between the support member 60 and the first heat sink 40 and the second heat sink 50 in the first direction Z. Among them, the fixed portion 61 of the support member 60 can utilize the thickness space of the first heat sink 40, and the free portion 63 of the support member 60 can utilize the thickness space of the second heat sink 50, thereby reducing the height difference between the support member 60 and the first heat sink 40 and the second heat sink 50 in the first direction Z, which is beneficial to improving the flatness of the screen 200 and improving the light and shadow effects of the screen 200.

[0120] In other embodiments, the housing device 100 may not include the first heat sink 40 and the second heat sink 50. In this case, the fixed portion 61 of the support member 60 can be directly fixed to the upper surface of the first middle frame 11. The free portion 63 of the support member 60 can directly overlap the upper surface of the second middle frame 21. When the electronic device 1000 is in the open state, the main body 62 can directly overlap the first support plate 33 and the second support plate 34 and can move relative to the first support plate 33 and the second support plate 34.

[0121] Figure 13 yes Figure 12 A schematic diagram of the structure when the structure shown is in a closed state. Figure 14 yes Figure 13 The structure shown is a cross-sectional view of an embodiment along line AA. Figure 15 yes Figure 13 The structure shown is a cross-sectional view from another perspective along line AA.

[0122] like Figure 12 As shown, when the electronic device 1000 is in the open state, the first support plate 33 and the second support plate 34 are flattened, and the main body 62 can be indirectly overlapped with the first support plate 33 and the second support plate 34 through the extension portion 42 of the first heat sink 40, and can move relative to the first support plate 33 and the second support plate 34. The free portion 63 can be indirectly overlapped with the second middle frame 21 through the extension portion 42 of the first heat sink 40, and can move relative to the second middle frame 21. At this time, the main body 62 can cover at least a portion of the first slit 36 ​​and at least a portion of the second slit 37 in the first direction Z. The overlapping portion of the free portion 63 and the second middle frame 21 in the first direction has a first length L1 in the second direction X.

[0123] like Figures 13-15 As shown, when the electronic device 1000 is in the closed state, the first support plate 33 and the second support plate 34 are folded, and the main body 62 can be bent and positioned between the first support plate 33 and the second support plate 34. In this case, the main body 62 can cover at least a portion of the first slit 36 ​​in the first direction Z. The free portion 63 can cover at least a portion of the second slit 37 in the first direction Z. The overlapping portion of the free portion 63 and the second middle frame 21 in the first direction has a second length L2 in the second direction X. The second length L2 is less than the first length L1.

[0124] When the electronic device 1000 transitions from an open state to a closed state, the fixed portion 61 of the support member 60 can remain connected to the first middle frame 11, while the free portion 63 of the support member 60 can shift relative to the second middle frame 21 in a direction closer to the main portion 62 under the combined action of the first middle frame 11, the second middle frame 21, and the hinge assembly 30. The main portion 62 of the support member 60 can bend. The fixed portion 61 and the free portion 63 of the support member 60 can transition from a relatively flat state to a relatively folded state.

[0125] Figure 16 yes Figure 3 The shown schematic diagram is a partial structural diagram of the housing device 100 in an open state from another perspective. Figure 17 yes Figure 12 The structure shown is a cross-sectional view of an embodiment along line BB.

[0126] like Figure 16 and Figure 17 As shown, the first lubricating member 70 can be fixedly connected to the surface of the extension portion 42 of the first heat sink 40 facing away from the support member 60. At this time, the extension portion 42 of the first heat sink 40 can be indirectly overlapped with the surface of the second heat sink 50 through the first lubricating member 70. The first lubricating member 70 can be a film or sheet with lubricating properties such as Teflon film. In this way, when the electronic device 1000 switches between the open state and the closed state, the first lubricating member 70 can reduce the friction between the first heat sink 40 and the second heat sink 50, so that the support member 60 and the first heat sink 40 can be relatively smoothly offset relative to the second middle frame 21, making the opening and closing of the electronic device 1000 smoother, which is conducive to improving the user experience.

[0127] Figure 18 yes Figure 1 The diagram shows a partial structure of the electronic device 1000 when it is in an open state. Figure 19 yes Figure 18 The structure shown is a cross-sectional view of an embodiment along line CC. Figure 20 yes Figure 18 The screen 200 of the electronic device 1000 is shown as a schematic diagram of an exploded structure in some embodiments.

[0128] like Figures 18-20 As shown, the second lubricating member 80 can be fixedly connected to the surface of the support member 60 facing away from the first heat dissipation member 40. The shape of the second lubricating member 80 can be substantially the same as that of the support member 60 ( Figure 3 and Figure 4 The second lubricating member 80 is also shown. The second lubricating member 80 may be a film or sheet with lubricating properties, such as a Teflon film.

[0129] Exemplarily, the screen 200 can include a flexible display screen 201 and a carrier plate 202 for supporting the flexible display screen 201. The carrier plate 202 can be located at the non-display side of the flexible display screen 201. Wherein, the flexible display screen 201 can be bent, and the carrier plate 202 can be bent and have a certain structural strength, so that the screen 200 can not only realize unfolding and folding actions, but also have a certain structural strength to have high structural reliability. Exemplarily, the middle part of the carrier plate 202 can be provided with a plurality of through holes 203. The extension directions of the plurality of through holes 203 can all be parallel to the second direction X. In this way, the plurality of through holes 203 can effectively reduce the rigidity of the middle part of the carrier plate 202. When the electronic device 1000 is bent, the middle part of the carrier plate 202 can better realize bending, which is conducive to improving the opening and closing experience of the electronic device 1000.

[0130] Exemplarily, the carrier plate 202 of the screen 200 can be fixedly connected with the first middle frame 11 and the second middle frame 21 of the shell device 100 by means of adhesive layer bonding or the like. At this time, the second lubricating member 80 can be located between the carrier plate 202 of the screen 200 and the supporting member 60. In this way, when the electronic device 1000 is converted between the open state and the closed state, the second lubricating member 80 can reduce the friction between the screen 200 and the supporting member 60, so that the supporting member 60 can relatively smoothly dislocate relative to the screen 200, so that the opening and closing of the electronic device 1000 is more smooth, which is conducive to improving the user experience. Secondly, the second lubricating member 80 can also separate the carrier plate 202 of the screen 200 and the supporting member 60, so that the carrier plate 202 and the supporting member 60 are insulated, thereby effectively avoiding the radiation stray problem between the screen 200 and the supporting member 60.

[0131] Figure 21 is Figure 18 the structural schematic diagram when the structure shown in the figure is in the closed state.

[0132] As Figure 21 shown, when the electronic device 1000 is in the closed state, the carrier plate 202 can be folded under the driving of the shell device 100. At this time, the middle part of the carrier plate 202 located above the hinge assembly 30 can be bent, and drive the flexible display screen 201 to deform together. The flexible display screen 201 can be bent under the driving of the carrier plate 202. The flexible display screen 201 and the carrier plate 202 can be jointly accommodated in the screen accommodating space 38 of the hinge assembly 30.

[0133] It can be understood that the electronic device 1000 in this embodiment can effectively enhance the anti-extrusion capability of the screen 200 when the electronic device 1000 is bent by arranging the support 60 between the screen 200 and the hinge assembly 30, thereby facilitating to enhance the structural reliability of the screen 200 and reducing the risk of damage of the screen 200 when the screen 200 is bent. Meanwhile, the support 60 can cover at least part of the first middle frame 11, at least part of the second middle frame 21 and at least part of the hinge assembly 30 in the first direction Z. In this way, when the electronic device 1000 is in the open state, the support 60 can cover the gap 35 of the hinge assembly 30, the first gap 36 between the first middle frame 11 and the hinge assembly 30 (in this embodiment, between the first middle frame 11 and the first support plate 33) and the second gap 37 between the second middle frame 21 and the hinge assembly 30 (in this embodiment, between the second middle frame 21 and the second support plate 34) in the first direction Z. When the electronic device 1000 is in the closed state, the support 60 can also cover the gap 35 of the hinge assembly 30, the first gap 36 and the second gap 37 in the first direction Z. In other words, whether the electronic device 1000 in this embodiment is in the open state or the closed state, the support 60 can block the gap, the first gap 36 and the second gap 37 of the hinge assembly 30, thereby effectively avoiding the screen 200 from being broken at the above positions and facilitating to improve the light and shadow of the screen 200.

[0134] In addition, compared with the electronic device in which both ends of the support are fixedly connected to the middle frame, in this embodiment, only one end (i.e., the fixed part 61 of the support 60) of the support 60 is fixed to the first middle frame 11, and the other end (i.e., the free part 63 of the support 60) of the support 60 is only overlapped on the second middle frame 21. In this way, when the electronic device 1000 is in the closed state and the support 60 is folded, the fixed part 61 of the support 60 does not move relative to the first middle frame 11 or moves slightly, and the free part 63 of the support 60 can move relative to the second middle frame 21 with the folding of the support 60, thereby effectively reducing the rebound force generated when the support 60 is folded, to avoid the support 60 from extruding the screen 200 when the support 60 is folded, to avoid the screen 200 from being wrinkled and damaged, to facilitate to improve the service life of the electronic device 1000 as a whole, and also to effectively reduce the rebound force when the whole machine is closed, to facilitate to improve the opening and closing experience of the electronic device 1000 as a whole.

[0135] In addition, the support member 60 can also cover the areas with weak structural strength and / or with steps of the hinge assembly 30, the first middle frame 11 and the second middle frame 21 in the first direction Z. In this way, the support member 60 can not only play a certain protective role on the areas with weak structural strength of the hinge assembly 30, the first middle frame 11 and the second middle frame 21, but also provide a relatively flat support environment for the screen 200, so as to effectively avoid the problem of unevenness of the screen 200 due to the stepped areas of the hinge assembly 30, thereby affecting the light and shadow effect of the screen 200.

[0136] The structure of the electronic device 1000, the structure of the shell device 100 and the position and connection relationship of the support member 60 and other components of the shell device 100 are specifically introduced above. The specific design of the support member 60 in some embodiments will be specifically introduced below in combination with the related drawings.

[0137] Please refer to Figure 11 and Figure 12 again, the support member 60 can be substantially in the shape of a cross. The length of the main body part 62 of the support member 60 in the third direction Y can be greater than the length of the fixed part 61 in the third direction Y and greater than the length of the free part 63 in the third direction Y. The main body part 62 of the support member 60 can include a first extension part 621, an intermediate part 622 and a second extension part 623. The intermediate part 622 can be connected between the fixed part 61 and the free part 63. The first extension part 621 can be located on the side of the intermediate part 622 close to the first end part 30a of the hinge assembly 30 and connected to the intermediate part 622. The second extension part 623 can be located on the side of the intermediate part 622 close to the second end part 30b of the hinge assembly 30 and connected to the intermediate part 622. In this way, the length of the main body part 62 of the support member 60 in the third direction Y is relatively long, so that it can better cover most of the area of the hinge assembly 30 in the first direction Z. The length of the fixed part 61 and the free part 63 of the support member 60 in the third direction Y is relatively short, so as to increase the area of the dispensing area of the screen 200 and the first middle frame 11 and the second middle frame 21, and reduce the influence of the support member 60 on the dispensing and fixing of the screen 200. In other embodiments, the support member 60 can also change its own shape according to actual needs, and the specific shape of the support member 60 is not limited in the present application. It should be understood that Figure 11 and Figure 12 both divide the first extension part 621, the intermediate part 622 and the second extension part 623 of the main body part 62 by dashed lines.

[0138] Exemplarily, the length of the fixed portion 61 in the second direction X can be less than the length of the free portion 63 in the second direction X. In this way, the extension portion 42 of the first heat dissipation member 40 can increase the area of the extension portion 42 while being covered by the support member 60, so as to increase the contact area between the first heat dissipation member 40 and the second heat dissipation member 50, so that the heat of the first heat dissipation member 40 can be transmitted to the second heat dissipation member 50 more quickly, and dissipated through the second heat dissipation member 50, effectively improving the overall heat dissipation efficiency of the electronic device 1000.

[0139] Exemplarily, the support member 60 can be provided with a first through hole group and a second through hole group arranged at intervals. The second through hole group can be located between the first through hole group and the free portion 63. The first through hole group can include a plurality of first holes 64. The plurality of first holes 64 can be arranged at intervals along the third direction Y. The plurality of first holes 64 can each be a strip-shaped hole. The extension direction of the plurality of first holes 64 can each intersect the third direction Y. The second through hole group can include a plurality of second holes 65. The plurality of second holes 65 can each be a strip-shaped hole. The plurality of second holes 65 can be arranged at intervals along the third direction Y. The extension direction of the plurality of second holes 65 can each intersect the third direction Y. When the electronic device 1000 is in the open state, the plurality of first holes 64 in the first through hole group can each expose part of the first support plate 33. The plurality of second holes 65 in the second through hole group can each expose part of the second support plate 34. In this embodiment, the extension direction of the plurality of first holes 64 and the extension direction of the plurality of second holes 65 can each be perpendicular to the third direction Y, i.e., parallel to the second direction X.

[0140] Exemplarily, the number of first holes 64 in the first through hole group can be the same as the number of second holes 65 in the second through hole group. The first through hole group and the second through hole group can be symmetrically arranged about the second axis T2. That is, the plurality of first holes 64 in the first through hole group can be symmetrically arranged about the second axis T2 with the plurality of second holes 65 in the second through hole group one-to-one corresponding. At this time, the plurality of second holes 65 can each be located on the side of the second axis T2 close to the free portion 63.

[0141] Exemplarily, the support member 60 can also have a shielding area 60a. The shielding area 60a can be located between the first through hole group and the second through hole group. At this time, the shielding area 60a can also be symmetrically arranged about the second axis T2. When the electronic device 1000 is in the open state, the shielding area 60a of the support member 60 can cover at least part of the gap 35 of the hinge assembly 30 in the first direction. It should be understood that, Figure 15 The gap 35 of the hinge assembly 30 is schematically shown by a narrower dashed line. It should be noted that the edge portion of the support member 60 can also cover the gap 35 in the first direction. The shielding area 60a of the support member 60 referred to in the present application refers to the shielding area 60a which can cover at least 80% of the gap 35 in the first direction.

[0142] The symmetrical arrangement can be completely symmetrical or approximately symmetrical. For example, the multiple first holes 64 within the first through-hole group and the multiple second holes 65 within the second through-hole group can be approximately symmetrically arranged about the second axis T2. For example, the multiple first holes 64 and the multiple second holes 65 located above the first end 30a of the rotating shaft assembly 30 can be asymmetrically arranged about the second axis T2. The multiple first holes 64 and the multiple second holes 65 located above the second end 30b of the rotating shaft assembly 30 can be asymmetrically arranged about the second axis T2. In this case, the portion of the shielding area 60a located above the first end 30a and the portion of the shielding area 60a located above the second end 30b can also be asymmetrically arranged about the second axis T2. In other words, the shielding area 60a can be approximately symmetrically arranged about the second axis T2. In this way, by changing the shape of the shielding area 60a to match the shape of the gap 35 of the rotating shaft assembly 30, the shielding area 60a of the support member 60 can effectively block the gap 35 of the rotating shaft assembly 30 in the first direction. It should be understood that Figure 11 and Figure 12 The second axis T2 is indicated by a dotted line in the figure. Subsequent figures also indicate the second axis T2 by dotted lines as needed. Figure 11 and Figure 12 In the figure, the shielding area 60a is also framed by a wider dotted line. For ease of understanding, the shielding area 60a framed by the dotted line is slightly larger than the actual shielding area 60a.

[0143] For example, at least a portion of the first hole 64 and at least a portion of the second hole 65 in the middle portion 622 of the main body 62 of the support member 60 can be longer in the second direction X. When the electronic device 1000 is in the open state, the portion of the first hole 64 in the middle portion 622 can simultaneously expose a portion of the first support plate 33 and a portion of the first middle frame 11. At least a portion of the second hole 65 in the middle portion 622 can simultaneously expose a portion of the second support plate 34 and a portion of the second middle frame 21. In other words, the portion of the first hole 64 in the middle portion 622 can expose a portion of the first gap 36 between the first support plate 33 and the first middle frame 11. At least a portion of the second hole 65 in the middle portion 622 can expose a portion of the second gap 37 between the second support plate 34 and the second middle frame 21.

[0144] In other embodiments, the extension directions of the plurality of first holes 64 in the first through hole group may not be completely the same. In other embodiments, the shapes of the plurality of first holes 64 in the first through hole group may also be other shapes, which are not specifically limited in this application.

[0145] Figure 22 yes Figure 12 The structural schematic diagram of the housing device 100 is shown.Figure 23 is Figure 13 a cross-sectional view of an embodiment of the structure shown in D-D.

[0146] As shown in Figure 22 , when the electronic device 1000 is in the open state, the plurality of first holes 64 and the plurality of second holes 65 can be flattened. The projection of the second axis T2 on the support 60 can be located between the projection of the first axis T1 on the support 60 and the free portion 63. The blocking area 60a can cover the gap 35 of the hinge assembly 30 in the first direction Z (see Figure 12 ). At least part of the first holes 64 located in the middle portion 622 can simultaneously expose part of the first support plate 33, part of the first middle frame 11, and part of the first gap 36. At least part of the second holes 65 located in the middle portion 622 can simultaneously expose part of the second support plate 34, part of the second middle frame 21, and part of the second gap 37.

[0147] As shown in Figure 22 and Figure 23 , when the electronic device 1000 is converted from the open state to the closed state, the fixed portion 61 of the support 60 can remain connected to the first middle frame 11, and the free portion 63 of the support 60 can be dislocated relative to the second middle frame 21 in a direction approaching the main body portion 62 under the joint action of the first middle frame 11, the second middle frame 21, and the hinge assembly 30. The plurality of first holes 64 and the plurality of second holes 65 can gradually bend in the second direction X. At this time, the second axis T2 of the support 60 can be dislocated relative to the first axis T1 of the hinge assembly 30 in a direction approaching the hinge assembly 30.

[0148] When the electronic device 1000 is in the closed state, the fixed portion 61 and the free portion 63 of the support 60 can be relative to the folding. The main body portion 62 of the support 60 can form a water droplet-shaped or similar water droplet-shaped inner space 60b. The inner space 60b can be located inside the screen containing space 38 of the hinge assembly 30. At this time, the plurality of first holes 64 and the plurality of second holes 65 can be bent in the second direction X. The projection of the second axis T2 of the support 60 on the support 60 can coincide or approximately coincide with the projection of the first axis T1 of the gap 35 on the support 60. At least part of the first holes 64 located in the middle portion 622 can simultaneously expose part of the first support plate 33, part of the first middle frame 11, and part of the first gap 36 (see Figure 15 ). At least part of the second holes 65 located in the middle portion 622 can simultaneously expose part of the second support plate 34, part of the second middle frame 21, and part of the second gap 37 (see Figure 14 ).

[0149] It can be understood that the support 60 in the embodiment effectively reduces the rebound force when the support 60 is folded by providing a plurality of first holes 64 and second holes 65 intersecting the third direction Y, so as to avoid the support 60 from being broken when it is folded, and to enhance the structural stability of the support 60 and prolong the service life of the support 60. At the same time, the first holes 64 and the second holes 65 can be bent along with the folding of the electronic device 1000, so as to effectively avoid the support 60 from pressing the screen 200 due to a large rebound force when it is folded, thereby effectively avoiding the screen 200 from being damaged due to wrinkles, and prolonging the service life of the screen 200, thereby prolonging the overall service life of the electronic device 1000. At the same time, it can also effectively reduce the rebound force when the entire electronic device 1000 is closed, and improve the opening and closing experience of the entire electronic device 1000 to enhance the user's experience.

[0150] Secondly, the plurality of first holes 64 of the support 60 in the embodiment can expose part of the first support plate 33, and the plurality of second holes 65 can expose part of the second support plate 34. The plurality of first holes 64 and the plurality of second holes 65 can be located at the main body part 62 of the support 60, i.e., at the part of the support 60 where the rebound force is large when it is bent, so that the setting of the first holes 64 and the second holes 65 can greatly reduce the rebound force of the main body part 62 of the support 60 when it is bent, thereby avoiding the main body part 62 from pressing the screen 200 when it is bent, to effectively avoid the screen 200 from being damaged due to wrinkles, and to further prolong the service life of the screen 200, thereby prolonging the overall service life of the electronic device 1000. At the same time, it can also further reduce the rebound force when the entire electronic device 1000 is closed, and improve the opening and closing experience of the entire electronic device 1000 to enhance the user's experience.

[0151] Secondly, the first and second through hole groups of the support 60 in the embodiment are spaced apart to avoid the area above the gap 35 of the hinge assembly 30 of the support 60, thereby forming a shielding area 60a between the first and second through hole groups, so that the support 60 can have the shielding area 60a capable of covering the gap 35 of the hinge assembly 30 in the first direction Z while reducing the rebound force of the support 60 by providing a plurality of first holes 64 and a plurality of second holes 65, thereby effectively avoiding the screen 200 from being broken at the gap 35 of the hinge assembly 30 when it is unfolded, and improving the light and shadow at the gap 35 of the hinge assembly 30 when the screen 200 is unfolded.

[0152] In addition, in the embodiment, when the electronic device 1000 is in the open state, the second axis T2 of the shielding area 60a is located on the side of the first axis T1 of the gap 35 close to the free part 63, that is, the shielding area 60a can be asymmetrically arranged about the first axis T1. The shielding area 60a can be reserved with a range of movement. In this way, when the electronic device 1000 is in the open state, the shielding area 60a can cover the gap 35 of the hinge assembly 30 in the first direction Z. When the electronic device 1000 is converted between the open state and the closed state, the range of movement reserved by the shielding area 60a makes the shielding area 60a not hooked with the first support plate 33 when the shielding area 60a moves relative to the hinge assembly 30, thereby effectively avoiding the problem that the support 60 is deformed due to being hooked with other components, which is beneficial to prolong the service life of the support 60, thereby being beneficial to prolong the overall service life of the electronic device 1000.

[0153] Furthermore, in the embodiment, the length of part of the first holes 64 and part of the second holes 65 is also extended, so that part of the first holes 64 can simultaneously expose part of the first support plate 33 and part of the first middle frame 11, and part of the second holes 65 can simultaneously expose part of the second support plate 34 and part of the second middle frame 21, regardless of whether the electronic device 1000 is in the open state or the closed state. In this way, regardless of whether the electronic device 1000 is in the open state or the closed state, part of the first holes 64 can expose the first gap 36 between part of the first support plate 33 and the first middle frame 11, and part of the second holes 65 can expose the second gap 37 between part of the second support plate 34 and the second middle frame 21, so that when the support 60 is converted between the unfolded state and the folded state, the force on the support 60 at the first gap 36 can be smoothly transferred through the plurality of longer first holes 64, and the force on the support 60 at the second gap 37 can be smoothly transferred through the plurality of longer second holes 65, thereby effectively avoiding the problem that the support 60 is broken at the first gap 36 and the second gap 37 due to a larger force, which is beneficial to enhance the structural stability of the support 60 to prolong the service life of the support 60, thereby being beneficial to prolong the overall service life of the electronic device 1000 and improve the user experience.

[0154] In addition, in the embodiment, the extension directions of the plurality of first holes 64 and the plurality of second holes 65 of the support 60 can all intersect the second direction X, that is, the plurality of through holes 203 (see FIG. 6) of the bearing plate 202 can be arranged in the second direction X, and the plurality of first holes 64 and the plurality of second holes 65 of the support 60 can be arranged in the first direction Z. Figure 20The extending directions of the first holes 64 and the second holes 65 of the support 60 intersect with the through hole 203 of the bearing plate 202, so that the mutual hooking and interference between the first holes 64 and the second holes 65 of the support 60 and the through hole 203 of the bearing plate 202 can be effectively avoided when the electronic device 1000 is switched between the open state and the closed state, and the deformation of the support 60 and / or the bearing plate 202 is avoided, thereby prolonging the service life of the support 60, prolonging the service life of the electronic device 1000 as a whole, and improving the user experience.

[0155] Figure 24 is Figure 11 a structural schematic view of the support 60. Figure 25 is Figure 1 a simplified schematic view of a partial structure of the electronic device 1000 in the open state. In the figure, Figure 25 In the figure, the fixed part 61, the main part 62, and the free part 63 of the support 60 are schematically boxed by a dashed line.

[0156] As shown in Figure 22 , Figure 24 and Figure 25 , the support 60 can further be provided with a third through hole group and a fourth through hole group. The third through hole group and the fourth through hole group can be located on different sides of the shielding area 60a. The third through hole group can be located between the shielding area 60a and the fixed part 61. The fourth through hole group can be located between the shielding area 60a and the free part 63. The third through hole group can include at least one third hole 66. The fourth through hole group can include at least one fourth hole 67. The number of the third holes 66 in the third through hole group can be the same as the number of the fourth holes 67 in the fourth through hole group. The third through hole group and the fourth through hole group can be symmetrically arranged about the second axis T2. In the embodiment, the number of the third holes 66 and the number of the fourth holes 67 can both be two. When the electronic device 1000 is in the open state, both of the two third holes 66 can expose part of the first support plate 33 and part of the first middle frame 11. Both of the two fourth holes 67 can simultaneously expose part of the second support plate 34 and part of the second middle frame 21. In some embodiments, the third hole 66 can also only expose part of the first support plate 33 or part of the first middle frame 11. The fourth hole 67 can also only expose part of the second support plate 34 or part of the second middle frame 21.

[0157] Exemplarily, the two third holes 66 in the third through hole group can be located above the first end part 30a and the second end part 30b of the hinge assembly 30, i.e., above the first extension part 621 and the second extension part 623 of the support 60, respectively. The two fourth holes 67 in the fourth through hole group can be located above the first end part 30a and the second end part 30b of the hinge assembly 30. In this way, the third through hole group and the fourth through hole group can avoid the longer first holes 64 in the first through hole group and the longer second holes 65 in the second through hole group.

[0158] For example, the length of the first holes 64 in the first hole group above the first end 30a of the rotating shaft assembly 30 and the length of the first holes 64 above the second end 30b in the second direction X are relatively short, so as to avoid the third holes 66 at the corresponding positions respectively. The length of the second holes 65 in the second hole group above the first end 30a of the rotating shaft assembly 30 and the length of the second holes 65 above the second end 30b in the second direction X are also relatively short, so as to avoid the fourth holes 67 at the corresponding positions respectively.

[0159] For example, the one or more first holes 64 with relatively short length around the third hole 66 and the one or more first holes 64 with relatively long length in the middle part 622 of the support 60 can be connected by one or more first holes 64 with moderate length. The second hole group is arranged in the same way as the first hole group, which will not be described here. In this way, when the electronic device 1000 is in the closed state and the support 60 is folded, the stress change of each part of the support 60 is relatively gentle, so as to effectively avoid the problem that the support 60 is broken due to the sudden change of the stress of the support 60 caused by the sudden change of the length of the first holes 64 and / or the second holes 65, thereby improving the structural reliability of the support 60 and prolonging the service life of the support 60.

[0160] Figure 26 is Figure 25 a simplified schematic view of the structure shown in the closed state. Among them, Figure 26 Each of the fixed part 61, the main part 62 and the free part 63 of the support 60 is schematically divided by a dashed line.

[0161] As Figure 25 and Figure 26As shown, the electronic device 1000 can further include a plurality of first adhesive layers 91 and a plurality of second adhesive layers 92. The plurality of first adhesive layers 91 can be located in the plurality of third holes 66 one-to-one and connected between the first support plate 33 and the screen 200. The plurality of second adhesive layers 92 can be located in the plurality of fourth holes 67 one-to-one and connected between the second support plate 34 and the screen 200. That is, the screen 200 can be fixedly connected to the first support plate 33 and the second support plate 34 through the plurality of first adhesive layers 91 in the third through-hole group and the plurality of second adhesive layers 92 in the fourth through-hole group, respectively. In this way, by providing at least one third hole 66 and at least one fourth hole 67 on the support member 60, the screen 200 can be fixedly connected to the shaft assembly 30 through the at least one third hole 66 and the at least one fourth hole 67, effectively increasing the fixing area between the screen 200 and the shaft assembly 30, reducing the influence of the support member 60 on the fixation of the screen 200, and facilitating to improve the connection stability between the screen 200 and the shell device 100.

[0162] Exemplarily, the third hole 66 can include a first edge 661 and a third edge 662 arranged oppositely. The first edge 661 can be located at an edge of the third hole 66 away from the shielding area 60a. The third edge 662 can be located at an edge of the third hole 66 close to the shielding area 60a. The fourth hole 67 can include a second edge 671 and a fourth edge 672 arranged oppositely. The second edge 671 can be located at an edge of the fourth hole 67 close to the shielding area 60a. The fourth edge 672 can be located at an edge of the fourth hole 67 away from the shielding area 60a. When the electronic device 1000 is in the open state, the first adhesive layer 91 is spaced apart from the first edge 661 of the third hole 66 corresponding thereto. The spacing between the first adhesive layer 91 and the first edge 661 of the third hole 66 corresponding thereto in the second direction X is a first width D1. The second adhesive layer 92 is spaced apart from the second edge 671 of the fourth hole 67 corresponding thereto. The spacing between the second adhesive layer 92 and the second edge 671 of the fourth hole 67 corresponding thereto in the second direction X is a second width D2. The first width D1 can be less than the second width D2. The first width D1 is greater than 0. When the electronic device 1000 is in the closed state, the first width D1 decreases. The second width D2 also decreases.

[0163] It can be understood that the electronic device 1000 in this embodiment is spaced apart from the first edge 661 of the third hole 66 corresponding to the first adhesive layer 91, so that a part of space in the third hole 66 is reserved to form a displacement space (i.e. the space between the first adhesive layer 91 and the first edge 661), and the second adhesive layer 92 is spaced apart from the second edge 671 of the fourth hole 67 corresponding to the second adhesive layer 92, so that a part of space in the fourth hole 67 is reserved to form a displacement space (i.e. the space between the second adhesive layer 92 and the second edge 671). In this way, when the electronic device 1000 is switched from the open state to the closed state, the free part 63 can move relative to the second middle frame 21 in the direction of approaching the main part 62, and the third hole 66 and the fourth hole 67 also move relative to the shaft assembly 30. Among them, the first edge 661 of the third hole 66 gradually approaches the first adhesive layer 91. The second edge 671 of the fourth hole 67 gradually approaches the second adhesive layer 92. Because the third hole 66 and the fourth hole 67 both reserve displacement spaces, the third hole 66 and the fourth hole 67 will not interfere with the first adhesive layer 91 and the second adhesive layer 92 even if they move relative to the shaft assembly 30. In other words, the electronic device 1000 in this embodiment will not interfere with the support 60 no matter whether it is in the open state or the closed state, so that the screen 200 can be stably fixed with the shaft assembly 30 no matter whether the electronic device 1000 is in the open state or the closed state, which is beneficial to improve the fixing stability of the screen 200.

[0164] Secondly, the third through hole group in this embodiment is located between the free part 63 and the fourth through hole group, that is, the third through hole group is closer to the free part 63 than the fourth through hole group. When the electronic device 1000 is in the closed state, the third hole 66 moves relative to the shaft assembly 30 by a distance greater than that of the fourth hole 67 relative to the shaft assembly 30. In this embodiment, the width (i.e. the first width D1) of the distance between the first edge 661 of the third hole 66 corresponding to the first adhesive layer 91 in the second direction X can be less than the width (i.e. the second width D2) of the distance between the second edge 671 of the fourth hole 67 corresponding to the second adhesive layer 92 in the second direction X. In this way, by setting the first width D1 to be less than the second width D2, the third hole 66 will not interfere with the first adhesive layer 91 when the electronic device 1000 is in the closed state, and at the same time, the fourth hole 67 will not interfere with the second adhesive layer 92, so that the screen 200 can be stably fixed with the shaft assembly 30 no matter whether the electronic device 1000 is in the open state or the closed state, which is beneficial to further improve the fixing stability of the screen 200.

[0165] In other embodiments, the third hole group can also only expose the first middle frame 11 according to the dispensing requirements of the screen 200. The fourth hole group can also only expose the second middle frame 21 according to the dispensing requirements of the screen 200.

[0166] In some embodiments, as shown in Figure 4 The second lubricating member 80 can be provided with a plurality of second avoiding holes 81. The number of the second avoiding holes 81 of the second lubricating member 80 can be the same as the sum of the number of the third holes 66 and the fourth holes 67 of the support member 60. In the present embodiment, the number of the second avoiding holes 81 of the second lubricating member 80 can be four. The four second avoiding holes 81 can be in one-to-one correspondence with the two third holes 66 and the two fourth holes 67, and respectively expose the two third holes 66 and the two fourth holes 67, so that the first glue layer 91 and the second glue layer 92 can be exposed to facilitate the bonding and fixing of the screen 200.

[0167] Figure 27 is a structural schematic view of the support member 60 in another embodiment. Figure 24

[0168] As shown in Figure 27 The support member 60 in the present embodiment is substantially the same as the support member 60 shown in Figure 22 The difference is that the third edges 662 of the plurality of third holes 66 in the third hole group of the support member 60 can be curved. The second edges 671 of the plurality of fourth holes 67 in the fourth hole group can be curved.

[0169] It can be understood that, in the present embodiment, the support member 60 is curved by arranging the third holes 66 close to the edge (i.e., the first edge 661) of the shielding area 60a and the fourth holes 67 close to the edge (i.e., the fourth edge 672) of the shielding area 60a. When the support member 60 is folded, the curved first edge 661 and the curved fourth edge 672 can both better uniformly release the stress at the location, thereby effectively avoiding the problem that the part of the support member 60 located at the first edge 661 and the fourth edge 672 is warped in the direction towards the outside of the electronic device 1000 (see Figure 26 ) and interferes with the first support plate 33 and / or the second support plate 34, causing the support member 60 to deform, which is beneficial to prolong the service life of the support member 60.

[0170] Figure 28 is a structural schematic view of the support member 60 in another embodiment. Figure 24 Figure 29 is a structural schematic view of the support member 60 in another embodiment. Figure 28

[0171] As shown in Figure 28 ​​​As shown, the support member 60 in this embodiment is Figure 24 The structure of the support member 60 shown is substantially the same, and the same parts will not be repeated. The difference is that the number of the third holes 66 in the third through hole group and the fourth holes 67 in the fourth through hole group of the support member 60 in this embodiment can both be three. Taking the third through hole group as an example, the three third holes 66 in the third through hole group can be arranged at intervals along the third direction Y. The three third holes 66 can be respectively located above the first end 30a, above the middle part 30c, and above the second end 30b of the rotating shaft assembly 30, and can all expose a portion of the first support plate 33 of the rotating shaft assembly 30 (see Figure 22 ). The configuration of the fourth through hole group is substantially the same as that of the third through hole group, and will not be described in detail here.

[0172] It can be understood that the support member 60 in this embodiment is provided with more third holes 66 and fourth holes 67, so that the support member 60 can expose more parts of the hinge assembly 30, thereby effectively increasing the fixing area of ​​the screen 200 and the hinge assembly 30, reducing the influence of the support member 60 on the gluing and fixing of the screen 200, which is beneficial to improving the connection stability between the screen 200 and the shell device and extending the service life of the electronic device 1000.

[0173] In other embodiments, Figure 29 As shown, the first edges 661 of the three third holes 66 of the support member 60 and the fourth edges 672 of the three fourth holes 67 can also be bent to reduce the stress at these locations when the support member 60 is bent.

[0174] Figure 30 yes Figure 24 The structure diagram of the support member 60 shown is in another embodiment.

[0175] like Figure 30 As shown, the structure of the support member 60 in this embodiment is similar to Figure 24 The structure of the support member 60 shown is substantially the same, and the common parts are not repeated here. The difference is that the support member 60 in this embodiment can also include a plurality of fifth holes 68. The plurality of fifth holes 68 can be located between the first group of through holes and the second group of through holes, that is, in the shielding area 60a of the support member 60. The plurality of fifth holes 68 can be arranged at intervals along the third direction Y. For example, the plurality of fifth holes 68 can be arranged at intervals along the second axis T2.

[0176] It can be understood that the support member 60 in this embodiment can effectively reduce the rebound force at the shielding area 60a when the support member 60 is folded by setting multiple fifth holes 68, reduce the risk of the support member 60 breaking, and is beneficial to improving the structural stability of the support member 60 and extending the service life of the electronic device 1000.

[0179] The above is only part of the embodiments of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application.
