Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0002] The flexible screen of an existing foldable phone is generally a multi-layer composite structure. When the flexible screen is converted from an unfolded state to a folded state, or when subjected to external impact force, some layers of the flexible screen will move relative to each other, causing some layers to collide with the shell of the foldable phone in the moving direction, which can easily cause the screen to fail. However, since the space inside a foldable phone is very limited, it is difficult to reserve additional space between the shell and the screen for the movement of the screen. Therefore, it is urgent to design an electronic device that can prevent the screen from moving under force and colliding with the shell. Summary of the invention

[0003] The purpose of the present application is to provide an electronic device to solve the problem that the screen of the existing electronic device collides with the housing due to movement caused by external force.

[0004] The present application provides an electronic device, which includes a screen module, a first shell and a second shell. The first shell is provided with a mounting groove, and the screen module is connected to the bottom surface of the mounting groove along the thickness direction of the electronic device, and there is a gap between the side surface of the screen module and the inner wall surface of the mounting groove. The second shell is provided with a connecting structure, and at least part of the connecting structure is arranged in the gap, and the second shell is connected to the first shell through the connecting structure; at least part of the connecting structure is provided with an avoidance portion, along a first direction, which is perpendicular to the thickness direction of the electronic device, and the avoidance portion is aligned with the screen module, and the avoidance portion is recessed or penetrated to the side away from the screen module, so as to enable part of the screen module to extend into the avoidance portion.

[0005] By providing an avoidance portion on the connecting structure of the second shell, the present application can widen the distance between the screen module and the connecting structure at a relative position to the screen module without changing the overall layout of the electronic device device structure, so that the screen module will not be blocked by the connecting structure after movement, and the screen module can be prevented from colliding with the connecting structure and being damaged when moving.

[0006] In a possible design, the connection structure includes two first connection parts, and along the first direction, the two first connection parts are respectively arranged at two ends of the second shell, and the two first connection parts are both arranged in the gap, and the avoidance part is provided on the two first connection parts.

[0007] Among them, the second shell can be fixedly connected to the first shell through two first connecting parts. Since the screen module does not move in the second direction, a connecting structure may not be set at both ends of the second shell in the second direction, which is beneficial to saving space of the electronic device in the second direction.

[0008] In a possible design, the connection structure also includes two second connection parts along a second direction, the second direction is perpendicular to the first direction and the thickness direction of the electronic device, the two second connection parts are respectively arranged at both ends of the second shell, the two second connection parts are both arranged in the gap, and the two second connection parts and the two first connection parts form a ring.

[0009] The second shell can be fixedly connected to the first shell via two first connection parts and two second connection parts, thereby ensuring the reliability of the connection between the second shell and the first shell.

[0010] In a possible design, along the thickness direction of the electronic device, the width of the avoidance portion is greater than or equal to the thickness of the screen module and less than the height of the first connecting portion.

[0011] Each layer of the screen module can be positioned relative to the avoidance portion, so that when any layer of the screen module moves, it can be avoided by the avoidance portion. In addition, the portion of the connection structure that is not provided with the avoidance portion can be connected and fixed to the first shell, thereby ensuring the reliability of the connection between the first shell and the second shell.

[0012] In a possible design, the connection structure includes two second connection parts, and the two second connection parts are respectively arranged at two ends of the second shell along the second direction, and the avoidance part is formed between the two second connection parts, and the avoidance part passes through along the first direction.

[0013] Among them, in the first direction, there is no connecting structure blocking the two ends of the screen module, so that the gap formed between the screen module and the inner wall surface of the installation groove of the first shell can provide sufficient space for the movement of the screen module, thereby avoiding the screen module from colliding with the first shell or the second shell in the first direction.

[0014] In a possible design, the connection structure is arranged on a side of the second shell facing the screen module. Thus, on the one hand, the connection structure can make full use of the space between the screen module and the first shell to realize the connection between the first shell and the second shell, avoiding the connection structure occupying extra space outside the first shell and the second shell. On the other hand, the connection structure can be limited by the inner wall of the mounting groove in the first shell to prevent the second shell from shaking relative to the first shell. At the same time, the connection structure can be shielded by the first shell, the second shell and the screen module to improve the appearance of the electronic device.

[0015] In a possible design, a groove is provided on the bottom surface of the mounting groove, and at least a portion of the connecting structure is fixedly disposed in the groove.

[0016] The portion of the connection structure extending into the groove can be fixedly connected to each inner surface of the groove, so that a larger fixing area can be provided between the connection structure and the first shell, thereby ensuring the reliability of the connection between the first shell and the second shell.

[0017] In a possible design, the connection structure is fixedly bonded to the groove by glue. The surfaces of the portion of the connection structure extending into the groove in all directions can be bonded to the corresponding inner surface of the groove by glue, thereby obtaining a larger connection area between the connection structure and the groove to ensure the reliability of the connection and fixation between the second shell and the first shell.

[0018] In a possible design, the second shell is formed in one piece, thereby ensuring that the second shell has good structural strength.

[0019] In a possible design, the material of the second shell is metal or plastic. Exemplarily, when the material of the second shell is metal, the second shell can have a smaller thickness, which is conducive to reducing the volume of the whole machine. Exemplarily, when the material of the second shell is plastic, it is conducive to achieving lightweight of the whole machine.

[0020] In a possible design, the electronic device further includes a buffer layer, and the two sides of the buffer layer are respectively in contact with the second housing and the screen module. When the electronic device is subjected to pressure in the thickness direction, the buffer layer can produce elastic deformation to relieve pressure, thereby preventing the screen module from being damaged by excessive pressure, thereby improving the reliability of the entire electronic device.

[0021] In a possible design, the buffer layer is foam, so that the buffer layer can obtain good resilience, good vibration reduction and impact absorption performance.

[0022] The present application also provides an electronic device, comprising a screen module, a first shell and a second shell. The first shell is provided with a mounting groove, and the screen module is mounted in the mounting groove along the thickness direction of the electronic device, and there is a gap between the side of the screen module and the inner wall surface of the mounting groove, and the gap can prevent the screen module from colliding with the first shell or the second shell when it moves.

[0023] Part of the second shell is arranged on one side of the first shell in the thickness direction, and can be pressed on the screen module, so that the screen module can be pressed and fixed by the first shell and the second shell in the thickness direction, ensuring the installation reliability of the screen module. Part of the second shell is arranged on the side of the first shell in the thickness direction away from the screen module, and part of the second shell can cover the outer side of the first shell.

[0024] Among them, the cross-sectional shape of the second shell is approximately "C"-shaped, which can cover part of the outer side surface of the first shell. On the one hand, it can ensure the reliability of the connection between the first shell and the second shell. On the other hand, there is no need to provide a connecting structure on the second shell for installation in the gap between the screen module and the inner wall surface of the mounting groove of the first shell, so that the screen module can be unobstructed near the end face in the movement direction, and the screen module can be prevented from colliding with the first shell or the second shell when moving.

[0025] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0077] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0078] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0079] For existing electronic devices such as folding mobile phones, they generally include a screen module and a shell. The screen module can be assembled on the shell, and some structures on the shell are located on the side of the screen module, and there is a small gap between the sides of the screen module. Among them, the screen module is generally a multi-layer structure. For example, the screen module includes a circuit layer, a display layer, a functional layer, etc. The circuit layer can feed power to the functional layer, and the display layer can be used to display text pictures, etc. These layers can be stacked in a certain order to form a screen module, and the layers can be bonded and fixed by glue. However, when the electronic device is subjected to external impact force, or for a foldable flexible screen, when the flexible screen is bent and folded, the forces on the various layers of the screen module are not uniform, which will cause relative movement between some layers. This movement will cause some layers in the screen module to collide with the structure on the shell located on the side of the screen module, which is easy to cause damage to the screen module. To this end, it is generally considered to increase the gap between the structure on the shell located on one side of the screen module and the screen module. However, the space inside the electronic device is very limited, and the gap cannot be increased under the existing structural layout. The only way is to increase the overall size of the electronic device so that the shell has space to adjust away from the screen module. However, this method is not conducive to the miniaturization of the electronic device.

[0080] Figure 1The schematic diagram of the structure of the electronic device provided in the embodiment of the present application is shown in FIG. Figure 1 , Figure 1 The electronic device is shown as a foldable mobile phone by way of example only. Of course, the electronic device can also be a mobile phone, a tablet computer, an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, a vehicle-mounted device, a smart home device and / or a smart city device, etc., which have a screen module. The embodiments of the present application do not impose any special restrictions on the specific type of the electronic device.

[0081] Figure 2 An exploded view of an electronic device provided in one embodiment of the present application, referring to Figure 2 The electronic device includes a screen module 1, a first shell 2 and a second shell 3, wherein the screen module 1 may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. As described above, the screen module 1 may include multiple layers, and the layers may be connected by adhesive, so that the screen module 1 is formed into an integral structure and can be installed as a whole between the first shell 2 and the second shell 3. The first shell 2 may be used to support various devices in the electronic device. For example, the screen module 1 may be fixed on the first shell 2 to achieve reliable support of the screen module 1 through the first shell 2. For example, referring to Figure 1 When the electronic device is a mobile phone, the first shell 2 can be a middle frame of the mobile phone. Figure 3 for Figure 1 The cross-sectional view at AA in the figure, Figure 4 In one embodiment of the present application, Figure 3 The enlarged view of point B in the middle (the screen module 1 has not moved). Figure 5 In one embodiment of the present application, Figure 3 The corresponding three-dimensional diagram of the structure at B (the screen module has not moved), combined with reference Figures 3 to 5 The second shell 3 can also be used to fix the screen module 1. At least part of the second shell 3 can be overlapped on the side of the screen module 1 facing away from the first shell 2, so that the screen module 1 is clamped between the first shell 2 and the second shell 3 to ensure the reliability of the fixation of the screen module 1.

[0082] Figure 6 This is a schematic diagram of the structure of the first housing 2 provided in the embodiment of the present application, referring to Figure 6The first housing 2 is provided with a mounting groove 21. Along the thickness direction Z of the electronic device, the screen module 1 is connected to the bottom surface 211 of the mounting groove 21. There is a gap between the side surface of the screen module 1 and the inner wall surface of the mounting groove 21. The depth of the mounting groove 21 is greater than the thickness of the screen module 1. The screen module 1 can be accommodated in the mounting groove 21 as a whole. The bottom surface 211 of the mounting groove 21 has a large area and can be used to support the screen module 1, thereby ensuring the installation reliability of the screen module 1 on the first housing 2. Figure 4 After the screen module 1 is installed in the mounting groove 21 , a gap a is still maintained between the side surface of the screen module 1 and the inner wall surface of the mounting groove 21 , so that the screen module 1 does not contact the inner wall surface of the mounting groove 21 .

[0083] Figure 7 This is a schematic diagram of the structure of the second housing 3 provided in one embodiment of the present application, referring to Figure 7 The second shell 3 is provided with a connection structure 31, and the second shell 3 is connected to the first shell 2 through the connection structure 31. Exemplarily, the connection structure 31 can be fixed to the first shell 2 by adhesive bonding to achieve relative fixation of the first shell 2 and the second shell 3. After the screen module 1 is installed in the installation groove 21 of the first shell 2, the connection structure 31 of the second shell 3 can be installed on the first shell 2 from the gap between the screen module 1 and the inner wall surface of the installation groove, so that part of the second shell 3 can be pressed on the side surface of the screen module 1 away from the first shell 2 (refer to Figure 4 ), so that the screen module 1 can be pressed and fixed by the first shell 2 and the second shell 3.

[0084] Among them, for the electronic device being a foldable product, the electronic device has a rotating shaft, and the electronic device can be folded or flattened through the rotating shaft. For the convenience of explanation, this embodiment defines the first direction X as a direction perpendicular to the extension direction of the rotating shaft, and the second direction Y as a direction parallel to the extension direction of the rotating shaft. The first direction X and the second direction Y are both perpendicular to the thickness direction Z of the electronic device. Figure 7 At least part of the connecting structure 31 is provided with an avoidance portion 313, referring to Figure 4 , along the first direction X, the avoidance portion 313 is aligned with the screen module 1, and the avoidance portion 313 is recessed or penetrated toward a side away from the screen module 1. Figure 5The first shell 2 includes a support portion 24 and a frame 25. The support portion 24 is used to support the screen module 1, and the frame 25 is convenient for users to hold and touch. A groove 22 is formed between the frame 25 and the support portion 24, and after the screen module 1 is installed on the support portion 24, a distance is maintained between the end of the screen module 1 and the frame 25. The second shell 3 includes a cover plate 35 and a connecting structure 31. The connecting structure 31 is connected to the cover plate 35 and protrudes from the side of the cover plate 35 facing the first shell 2. Part of the connecting structure 31 can extend into the groove 22 and can be fixedly connected to the first shell 2 by gluing or other methods. At this time, the cover plate 35 can be pressed against the side of the screen module 1 away from the support portion 24. The connecting structure 31 has an avoidance portion 313. In the first direction X, the projection of the avoidance portion 313 at least partially overlaps with the projection of the screen module 1, and the projection of the screen module 1 in the first direction is located within the projection range of the avoidance portion 313 in the first direction.

[0085] Reference Figure 4 and Figure 7 For example, the avoidance portion 313 may be a through hole extending along the first direction X. Figure 8 In another embodiment of the present application, Figure 3 The enlarged image of point B in the middle (screen module 1 is moving), Fig. 9 In another embodiment of the present application, Figure 3 The three-dimensional diagram corresponding to the structure at B in the middle (the screen module moves), combined with reference Figure 8 and Fig. 9 When the screen module 1 is subjected to an external force and moves in the first direction X, the movement may be relative movement between the layers in the screen module 1, or the screen module 1 as a whole may move relative to the first shell 2 and the second shell 3. The end of the screen module 1 may extend into the avoidance portion 313. That is, in the direction of the movement of the screen module 1, by setting the avoidance portion 313, the distance between the screen module 1 and the position relative to the screen module 1 on the connection structure 31 can be widened without changing the overall layout of the electronic device structure, so that the screen module 1 will not be blocked by the connection structure 31 after the movement, and the screen module 1 can be prevented from hitting the connection structure 31 and being damaged during the movement. Figure 8 and Fig. 9 When the avoidance portion 313 is a through hole, the through hole can provide a larger avoidance space for the screen module 1 in the first direction X, thereby effectively preventing the screen module 1 from colliding with the connection structure 31 or the inner wall surface of the installation groove 21.

[0086] Fig.10 In another embodiment of the present application, Figure 3 The enlarged view of point B in the middle (screen module 1 is moving), refer to Fig.10 , Fig.10 It is exemplarily shown that the avoidance portion 313 is a recessed structure, which is recessed from the side of the connecting structure 31 close to the screen module 1 to the side away from the screen module 1, thereby widening the distance between the connecting structure 31 and the screen module 1 at the position of the avoidance portion 313, so that the screen module 1 can partially extend into the recessed position when movement occurs, thereby avoiding collision between the screen module 1 and the connecting structure 31.

[0087] In one implementation, Fig.11 A perspective view of a second housing 3 provided in an embodiment of the present application, referring to Fig.11 , the connection structure 31 includes two first connection parts 311. Taking the movement of the screen module 1 in the first direction X as an example, along the first direction X, the two first connection parts 311 are respectively arranged at the two ends of the second shell 3, and the two first connection parts 311 are provided with avoidance parts 313. In this embodiment, the second shell 3 can be fixedly connected to the first shell 2 through the two first connection parts 311. For example, the two first connection parts 311 can be fixedly bonded to the first shell 2 by glue. Since the screen module 1 does not move in the second direction Y, the connection structure 31 may not be provided at the two ends of the second shell 3 in the second direction Y, which is conducive to saving space of the electronic device in the second direction Y.

[0088] For example, refer to Fig.11 For an electronic device that is a foldable mobile phone, in order to realize the folding function, the second shell 3 may include a first part 32 and a second part 33. The first part 32 and the second part 33 may be respectively arranged on both sides of the bendable area on the foldable mobile phone. The structures of the first part 32 and the second part 33 may be the same, and the first part 32 and the second part 33 may both have a first connecting portion 311.

[0089] For example, Fig.12 A perspective view of a second housing 3 provided in another embodiment of the present application, referring to Fig.12 For electronic devices such as tablet computers and bar phones, the second housing 3 may be an integrated structure, thereby ensuring the overall structural reliability of the second housing 3. In this embodiment, the two first connecting portions 311 and the two second connecting portions 312 may form a continuous closed annular structure.

[0090] In one implementation, Fig.13 A perspective view of a second housing 3 provided in another embodiment of the present application is shown in FIG. Fig.13The connection structure 31 also includes two second connection parts 312, along the second direction Y, the second direction Y is perpendicular to the first direction X and the thickness direction Z of the electronic device. As described above, the second direction Y is parallel to the extension direction of the length of the electronic device shaft. The two second connection parts 312 are respectively arranged at the two ends of the second shell 3, and the two second connection parts 312 are both arranged in the gap, and the two second connection parts 312 and the two first connection parts 311 are surrounded by a ring. In this embodiment, the second shell 3 can be fixedly connected to the first shell 2 through the two first connection parts 311 and the two second connection parts 312, so as to ensure the reliability of the connection between the second shell 3 and the first shell 2.

[0091] For example, refer to Fig.13 , as described above, for the electronic device being a folding mobile phone, in order to realize the folding function, the second housing 3 may include a first portion 32 and a second portion 33, which may be respectively arranged on both sides of the bendable area of ​​the folding mobile phone, and the structures of the first portion 32 and the second portion 33 may be the same, and the first portion 32 and the second portion 33 may both have a first connection portion 311 and a second connection portion 312. Among them, taking the first portion 32 as an example, the two ends of the first connection portion 311 are respectively connected to a second connection portion 312, so that the first connection portion 311 and the two second connection portions 312 form an approximately "C"-shaped structure. When the first portion 32 and the second portion 33 are installed on the electronic device, the "C"-shaped structure of the first portion 32 and the second portion 33 may be enclosed in a ring.

[0092] For example, Fig.14 A perspective view of a second housing 3 provided in another embodiment of the present application, referring to Fig.14 As described above, for the electronic device being a tablet computer or a bar phone, the second housing 3 may be an integrated structure, thereby ensuring the overall structural reliability of the second housing 3. In this embodiment, the two first connecting portions 311 and the two second connecting portions 312 may form a continuous closed annular structure.

[0093] In one implementation, Fig.15 A side view of the second housing 3 provided in one embodiment of the present application, referring to Fig.15 Along the thickness direction Z of the electronic device, the first connection portion 311 has a height H1, and the avoidance portion 313 has a width H2. Figure 4, along the thickness direction Z of the electronic device, the width H2 of the avoidance portion 313 is greater than or equal to the thickness H3 of the screen module 1, and less than the height H1 of the first connection portion 311. Among them, each layer of the screen module 1 can be positioned opposite to the avoidance portion 313, so that when any layer of the screen module 1 moves, it can be avoided by the avoidance portion 313. In addition, the portion of the connection structure 31 that is not provided with the avoidance portion 313 can be connected and fixed to the first shell 2, thereby ensuring the reliability of the connection between the first shell 2 and the second shell 3.

[0094] In addition, in some other embodiments, the width H2 of the avoidance portion 313 may also be slightly smaller than the thickness H3 of the screen module 1. In this embodiment, the difficulty of relative movement between the various layers of the screen module 1 and between the screen module 1 and the first shell 2 is different. For example, a layer on the screen module 1 that is connected to the first shell 2 has a higher reliability of connection with the first shell 2 and is less likely to move than other layers. Therefore, the avoidance portion 313 can be made relative to other layers on the screen module 1 other than the layer used to connect to the first shell 2. On the one hand, it is possible to avoid the various layers on the screen module 1 that are prone to movement. On the other hand, it is also possible to reduce the material removed from the connecting structure 31 due to the provision of the avoidance portion 313, thereby ensuring the structural strength of the connecting structure 31 and ensuring the reliability of the connection and fixation of the first shell 2 and the second shell 3 through the connecting structure 31.

[0095] In one implementation, Fig.16 This is a schematic diagram of the structure of the second housing 3 provided in another embodiment of the present application. Fig.17 A side view of the second housing 3 provided in another embodiment of the present application, referring to Fig.16 and Fig.17 The connection structure 31 includes two second connection parts 312. Along the second direction Y, the two second connection parts 312 are respectively arranged at both ends of the second shell 3. The second shell 3 can be reliably connected to the first shell 2 through the two second connection parts 312. An avoidance part 313 is formed between the two second connection parts 312, and the avoidance part 313 passes through along the first direction X.

[0096] Fig.18 In another embodiment of the present application, Figure 3 The enlarged view of point B in the middle, refer to Fig.18 In this embodiment, in the first direction X, there is no connection structure 31 blocking the two ends of the screen module 1, so that the gap a formed between the screen module 1 and the inner wall surface of the mounting groove 21 of the first shell 2 can provide sufficient space for the movement of the screen module 1, thereby preventing the screen module 1 from colliding with the first shell 2 or the second shell 3 in the first direction X.

[0097] In one implementation, the connection structure 31 is disposed on a surface of the second housing 3 facing the screen module 1, and the connection structure 31 protrudes from the surface of the second housing 3, so that the connection structure 31 can extend into the gap between the screen module 1 and the first housing 2. For example, referring to Figure 4 When the connection structure 31 includes a first connection portion 311, the first connection portion 311 is arranged on the side of the second shell 3 facing the screen module 1, and can extend into the gap a; in addition, when the connection structure 31 includes a first connection portion 311 and a second connection portion 312, the first connection portion 311 and the second connection portion 312 are both arranged on the side of the second shell 3 facing the screen module 1, and can extend into the corresponding gap. Thus, on the one hand, the connection structure 31 can make full use of the space between the screen module 1 and the first shell 2 to realize the connection between the first shell 2 and the second shell 3, avoiding the connection structure 31 from occupying additional space outside the first shell 2 and the second shell 3. On the other hand, the connection structure 31 can be limited by the inner wall of the mounting groove 21 in the first shell 2 to prevent the second shell 3 from shaking relative to the first shell 2. At the same time, the connection structure 31 can be shielded by the first shell 2, the second shell 3 and the screen module 1 to improve the appearance of the electronic device.

[0098] In one implementation, referring to Figure 6 The bottom surface 211 of the mounting groove 21 is provided with a groove 22, referring to Figure 4 , at least part of the connecting structure 31 is fixedly disposed in the groove 22. The part of the connecting structure 31 extending into the groove 22 can be fixedly connected to each inner surface of the groove 22, so that a larger fixing area can be provided between the connecting structure 31 and the first shell 2, thereby ensuring the reliability of the connection between the first shell 2 and the second shell 3.

[0099] For example, the connection structure 31 can be fixedly bonded in the groove 22 by glue. The surfaces of the portion of the connection structure 31 extending into the groove 22 in all directions can be bonded to the corresponding inner surface of the groove 22 by glue, thereby obtaining a larger connection area between the connection structure 31 and the groove 22 to ensure the reliability of the connection and fixation between the second shell 3 and the first shell 2.

[0100] In one implementation, the second shell 3 may be an integrally molded structure. For example, during the molding process of the second shell 3 , the first connecting portion 311 and the second connecting portion 312 may be molded simultaneously, thereby ensuring that the second shell 3 has good structural strength.

[0101] The material of the second shell 3 may be metal or plastic. For example, when the material of the second shell 3 is metal, the second shell 3 may have a smaller thickness, which is beneficial to reducing the volume of the whole machine. For example, when the material of the second shell 3 is plastic, it is beneficial to achieve lightweight of the whole machine.

[0102] In one implementation, referring to Figure 2 The electronic device further comprises a buffer layer 4, referring to Figure 4 , the two sides of the buffer layer 4 are respectively in contact with the second shell 3 and the screen module 1. On the one hand, the buffer layer 4 can be blocked between the screen module 1 and the second shell 3 to avoid rigid contact between the screen module 1 and the second shell 3. On the other hand, the buffer layer 4 has a certain elasticity. When the buffer layer 4 is under pressure, a certain elastic deformation can occur to achieve the effect of buffering pressure. In this embodiment, when the electronic device is subjected to pressure in the thickness direction Z, the buffer layer 4 can produce elastic deformation to achieve pressure relief, thereby preventing the screen module 1 from being damaged by excessive pressure, thereby improving the reliability of the entire electronic device.

[0103] Optionally, the buffer layer 4 may be foam, so that the buffer layer 4 can obtain good resilience, good vibration reduction and impact absorption performance.

[0104] Of course, in some other embodiments, the buffer layer 4 may also be made of other flexible polymer materials, such as silica gel, etc., which is not limited in this embodiment.

The first shell 2 is provided with a mounting groove 21. The screen module 1 is installed in the mounting groove 21, and there is a gap a between the side surface of the screen module 1 and the inner wall surface of the mounting groove 21. The gap a can prevent the screen module 1 from colliding with the first shell 2 or the second shell 3 when it moves.

[0106] in, Fig. 22 for Fig.19 The cross-sectional view at CC in the figure, Fig.23 for Fig. 22 The enlarged view at D in Fig. Fig.23, part of the second shell 3 is arranged on one side of the first shell 2 in the thickness direction Z, and can be pressed on the screen module 1, so that the screen module 1 can be pressed and fixed by the first shell 2 and the second shell 3 in the thickness direction Z, ensuring the installation reliability of the screen module 1. Part of the second shell 3 is arranged on the side of the first shell 2 away from the screen module 1 in the thickness direction Z, and part of the second shell 3 can cover the outer side of the first shell 2. In other words, Fig.23 The cross-sectional shape of the second shell 3 shown is approximately "C"-shaped, and can cover part of the outer side surface of the first shell 2. On the one hand, it can ensure the reliability of the connection between the first shell 2 and the second shell 3. On the other hand, there is no need to provide a connecting structure 31 on the second shell 3 for installation at the gap a between the inner wall surface of the installation groove 21 of the screen module 1 and the first shell 2, so that the screen module 1 can be unobstructed near the end surface in the movement direction, and the screen module 1 can be prevented from colliding with the first shell 2 or the second shell 3 when moving.

[0107] In order to further ensure the reliability of the connection between the second shell 3 and the first shell 2, part of the second shell 3 can be connected and fixed to the first shell 2 by screws 6. Fig.23 The second housing 3 may be provided with a mounting hole at a portion away from the screen module 1, and the first housing 2 may be provided with a threaded hole 23, through which the screw 6 may pass and be fastened in the threaded hole 23 of the first housing 2. The electronic device may further include a back cover 5, which may be fixed on a side of the first housing 2 away from the screen module 1, and the screw 6 and a portion of the second housing 3 may be shielded by the back cover 5. On the one hand, the connection position between the first housing 2 and the second housing 3 may be shielded and protected from dust and dirt, and on the other hand, the appearance of the electronic device may be improved.

During the installation process of the first shell 2 and the second shell 3, the bending portion 34 of the second shell 3 can be inserted into the groove of the first shell 2, so that the mounting hole can be aligned and connected with the threaded hole 23, and then it can be fastened in the mounting hole and the threaded hole 23 by the screw 6. Therefore, by providing the bending portion 34 on the second shell 3, the reliability of the connection between the second shell 3 and the first shell 2 can also be guaranteed.
