DETAILED DESCRIPTION

[0036] The present application provides an electronic device that has a foldable function and enables a display screen to be used by users in areas of different sizes, thereby well meeting the user's various usage needs.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] See also Figure 1 to Figure 13The embodiment of the present application provides an electronic device, which can be of various types such as a computer, a mobile phone, etc. The electronic device includes a display screen 4, a hinge device 3 and two rotationally connected bodies, wherein the two bodies are rotationally connected through the hinge device 3, and the display screen 4 is arranged on a target body, and the target body is at least one of the two bodies, that is, the target body can be any one of the two bodies, or both of the two bodies. The display screen 4 includes a first part and a second part adjacent to each other, and the first part of the display screen 4 has a curled state and an extended state, that is, the display screen 4 sets at least the first part thereof as a flexible structure that can be bent (for example, the first part of the display screen can be a flexible display screen, or the entire display screen can be a flexible display screen). The target body includes a first sub-body 11 and a second sub-body 12, the first end of the first sub-body 11 is connected to the hinge device 3, the second end is movably connected to the second sub-body 12, the second part of the display screen 4 is connected to the second sub-body 12, when the second sub-body 12 moves relative to the first sub-body 11, the first part of the display screen 4 switches between the curled state and the extended state, that is, the second part of the display screen 4 can move relative to the first sub-body 11 together with the second sub-body 12, at this time, the first part of the display screen 4 can switch from the curled state to the extended state, or from the extended state to the curled state. It is easy to understand that the state switching direction of the first part of the display screen 4 is related to the movement direction of the second part of the display screen 4 relative to the first sub-body 11. The hinge device 3 includes a receiving space, and when the first part of the display screen 4 is in the curled state, the first part of the display screen 4 is located in the receiving space. When in use, the relative rotation of the two bodies can make the electronic device folded or opened, and the first part of the display screen 4 can be switched from a curled state to an extended state, thereby extending to the outside of the accommodating space of the hinge device 3 and being exposed, so that the display screen 4 can be provided to the user with a larger area. When the user needs to use a display screen 4 with a smaller area, the first part of the display screen 4 can be switched from an extended state to a curled state. It can be seen that the electronic device provided by the present application has a foldable function, and the exposed area of ​​the display screen 4 can be changed through the relative movement of the second sub-body 12 and the first sub-body 11, so that the display screen 4 can be provided to the user with areas of different sizes, which well meets the user's various different usage needs.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the electronic device may include a first body 1 and a second body 2 that are rotatably connected via a rotating shaft device 3. The first body 1 and the second body 2 may have a closed state and an open state based on the rotatable connection. In the closed state, the first body 1 and the second body 2 are in a stacked state, for example Figure 1 In the state shown, in the open state, a certain angle is formed between the first body 1 and the second body 2, for example Figure 2 and Figure 4 When the first body 1 and the second body 2 are in a closed state, and the second sub-body 12 is at the target position closest to the first end of the first sub-body 11, the projection areas of the first body 1 and the second body 2 onto each other can be the same. Figure 5 As shown, the first end of the first sub-body 11 is connected to the shaft device 3, and the second sub-body 12 can be connected along Figure 5 The hollow arrow in the figure moves relative to the first sub-body 11, thereby approaching or moving away from the first end of the first sub-body 11, that is, approaching or moving away from the hinge device 3. When the second sub-body 12 moves to the limit position in the direction close to the hinge device 3, the second sub-body 12 reaches the position closest to the first end of the first sub-body 11, that is, the aforementioned target position. At this time, the foldable electronic device causes the first body 1 and the second body 2 to rotate relative to each other as shown in FIG. Figure 1 In the closed state shown, the projection areas of the first body 1 and the second body 2 onto each other can be the same, that is, the first body 1 and the second body 2 can be in a stacked state with overlapping areas. The projection areas of the first body 1 and the second body 2 onto each other are the same, which can make the overall appearance of the folded electronic device neater and avoid the formation of an abrupt structure similar to a step at the edge of the first body 1 and the second body 2. Figure 1 The status shown opens directly to Figure 2 In the state shown, the exposed area of ​​the display screen 4 can meet the needs of most daily use scenarios of users. When the user needs the display screen 4 to provide a larger exposed area, the second sub-body 12 can be moved relative to the first sub-body 11, so that the electronic device is Figure 2 The status shown changes to Figure 4 The status shown is OK.

[0040] like Figure 3 and Figure 4 As shown, in some embodiments, the target body can be one of the two bodies, and the hinge device can include a first rotating element 31 and a second rotating element that are rotatably connected. The first rotating element 31 has the aforementioned accommodation space and can be constructed as a part of the target body, and the second rotating element can be constructed as a part of the other body of the two bodies. For example, the target body is the first body 1, and the display screen 4 is arranged on the first body 1. The first rotating element 31 of the hinge device 3 has an accommodation space, and the first rotating element 31 can be set as an integral structure with the first sub-body 11, so that the first rotating element 31 becomes a part of the first body 1, and the second rotating element of the hinge device 3 can be set as an integral structure with the second body 2, so that the second rotating element becomes a part of the second body 2. By respectively constructing the first rotating element 31 and the second rotating element as parts of the two bodies, the overall structural strength of the electronic device can be improved. As shown Figure 3As shown, in some embodiments, the second body 2 may be a host part of the electronic device, the first body 1 may be a display part of the electronic device, and components such as a keyboard assembly and a touchpad may be provided on the second body 2.

[0041] See also Figure 5 , Figure 6 and Figure 8 In some embodiments, the electronic device may include a first support body 5 located in the accommodation space of the hinge device 3, the first support body 5 is rotatably connected to the first rotating element 31, and the rotation center line of the first support body 5 relative to the first rotating element 31 is located on the axis of the first support body 5, that is, the first support body 5 can rotate around its own central axis. When the first part of the display screen 4 is in a rolled state, the first part of the display screen 4 is rolled up on the first support body 5, that is, the first support body 5 supports the first part of the display screen 4 in the rolled state, so that the first part of the display screen 4 can be more regularly and stably maintained in the accommodation space of the hinge device 3. The first support body 5 can be set to a cylindrical shape, so that the first part of the display screen 4 will not bend to a large extent when it is rolled up on the first support body 5, which is conducive to avoiding damage to the part of the display screen 4 due to excessive bending. In other embodiments, the first support body 5 can be set to other shapes, for example, set to a cylindrical shape with an elliptical cross section. When the first support body 5 is set to a cylindrical shape, the first rotating element 31 can be set to a cylindrical shape and coaxially arranged with the first support body 5. The first rotating element 31 is set to be cylindrical. On the one hand, it can make the appearance of the electronic device at the hinge device 3 rounded and improve the comfort of holding. On the other hand, it can be coaxially matched with the cylindrical first support body 5 to make better use of the accommodating space of the first rotating element 31 and avoid excessive wasted space between the inner wall of the accommodating space and the first support body 5.

[0042] In other embodiments, in order to achieve switching between the curled state and the extended state of the first part of the display screen 4, the first rotating element 31 can open a spiral guide groove on two opposite inner walls of the accommodating space, and the guide grooves on the two inner walls respectively slide with the side edges of the first part of the display screen 4. In the process of the first part of the display screen 4 moving into the accommodating space, the side edges of the display screen 4 move along the guide grooves, so that the first part of the display screen 4 is curled and deformed. In the process of the first part of the display screen 4 moving out of the accommodating space, the side edges of the display screen 4 gradually withdraw from the guide grooves, so that the first part of the display screen 4 is switched to the extended state.

[0043] In order to better utilize the storage space of the rotating shaft device 3, other components may be arranged in the storage space. For example, in some embodiments, the electronic device may include a power storage component 9 electrically connected to the display screen 4, and the power storage component 9 is located in the storage space. The power storage component 9 may be of various types. For example, the power storage component 9 may be a capacitor or a battery. In the case where the power storage component 9 is a battery, the power storage component 9 may be a lithium battery. Fig.12 As shown, in order to make the overall structure of the rotating shaft device 3 compact, the first support body 5 can be set as a cylinder with a hollow structure, and the power storage component 9 can be arranged in the first support body 5. The power storage component 9 can be set as a cylinder, or can be set as other shapes such as a cuboid or a cube. For another example, in some embodiments, the electronic device can include a control board 6 electrically connected to the display screen 4, and the control board 6 can be located in the accommodating space of the rotating shaft device 3. In the case where the first support body 5 is set as a cylinder with a hollow structure, the control board 6 can be arranged in the first support body 5.

[0044] like Figure 5 and Figure 6 As shown, when a user uses the electronic device, the first part of the display screen 4 can be rolled up onto the first support body 5 in the rotating shaft device 3 by relatively moving the second sub-body 12 and the first sub-body 11. For example, the user moves along Figure 5 The hollow arrow pointing downward pushes the second sub-body 12, so that the second sub-body 12 moves relative to the first sub-body 11 toward the direction close to the rotating shaft device 3. During the movement of the display screen 4 along with the second sub-body 12, the first support body 5 is driven to rotate, and the first part of the display screen 4 is wound onto the first support body 5. Fig.13 As shown, in order to make the above operation of the user more labor-saving, in some embodiments, the electronic device may include a winding drive member 10 located in the first rotating element 31, and the winding drive member 10 is connected to the first support body 5, and is used to drive the first support body 5 to rotate to roll up the first part of the display screen 4. There are many types of winding drive members 10 to choose from. For example, the winding drive member 10 can be set as a winding spring. When the user moves along the winding spring, the winding drive member 10 can be rotated to roll up the first part of the display screen 4. Figure 5 When the second sub-body 12 is pulled upward by the hollow arrow in the middle, so that the second sub-body 12 moves relative to the first sub-body 11 in the direction away from the rotating shaft device 3, the display screen 4 moves with the second sub-body 12 and drives the first supporting body 5 to rotate. The rotation of the first supporting body 5 causes the coil spring to accumulate elastic potential energy. The elastic potential energy of the coil spring is Figure 5The downward hollow arrow in the middle pushes the second sub-body 12 and releases it, providing power for the rotation of the first support body 5, so that the user can push the second sub-body 12 with less effort. The winding drive member 10 can also be configured as other components that can accumulate elastic potential energy, such as leaf springs. In addition, the winding drive member 10 can also be configured as a micro motor, the output shaft of the micro motor is connected to the first support body 5, and the micro motor can provide power for the rotation of the first support body 5 when working.

[0045] See also Figure 8~Figure 11 In some embodiments, a cushion structure 82 may be provided on the side of the first part of the display screen 4 that faces away from the display surface. The cushion structure 82 can be deformed by curling with the first part and can support the first part in the extended state. The display surface refers to the side of the display screen 4 that outputs the display content. The first part of the display screen 4 is located outside the hinge device 3 in the extended state. If the cushion structure 82 is not provided, there will be a gap between the back side of the first part of the display screen 4, that is, the side facing away from the display surface, and the first sub-body 11. The gap will affect the user's operation of the display screen 4, such as touching. The cushion structure 82 can support the first part of the display screen 4 in the extended state, so that the first part of the display screen 4 can be prevented from being excessively sunken when the user touches it.

[0046] like Figure 8 and Fig.10 As shown, in some embodiments, the cushion structure 82 can be fixedly connected to the display screen 4 through the connecting layer 81. The thickness of the connecting layer 81 is much smaller than the thickness of the cushion structure 82, which will not affect the supporting function of the cushion structure 82 on the first part of the display screen 4. On the one hand, the connecting layer 81 can protect the display screen 4 between the display screen 4 and the cushion structure 82, and prevent the relatively hard cushion structure 82 from causing damage to the display screen 4 during curling and deformation. On the other hand, it can enhance the connection strength between the cushion structure 82 and the display screen 4, so that the cushion structure 82 and the display screen 4 are not easy to loosen during use. The connecting layer 81 and the display screen 4, as well as the connecting layer 81 and the cushion structure 82, can be connected by adhesive.

[0047] In some embodiments, a side of the cushion structure 82 facing away from the first portion of the display screen 4 may be provided with a plurality of mutually parallel expansion grooves 83, and the extension direction of the expansion grooves 83 is parallel to the axis of the first support body 5. Figure 8 and Fig.10As shown, if the cushion structure 82 is not provided with an expansion groove 83, then when the cushion structure 82 is curled and deformed, the outer side of the bend of the cushion structure 82 will be subject to a strong tensile restriction, which will cause the inner side of the bend to be subject to a greater extrusion force, thereby applying a greater external force to the display screen 4, which can easily cause the display screen 4 to be squeezed and damaged. The provision of the expansion groove 83, on the one hand, reduces the force exerted by the inner side of the bend on the display screen 4 when the cushion structure 82 is curled and deformed, and on the other hand, makes the cushion structure 82 more likely to curl and deform. The depth of the expansion groove 83 can be more than half of the thickness of the cushion structure 82, and the width of the expansion groove 83 should not be too large to avoid affecting the cushion structure 82 from playing a supporting role on the display screen 4. In other embodiments, the cushion structure 82 may adopt other structural forms to achieve the purpose of reducing the inner side squeezing force of the bend and facilitating curling and deformation. For example, the cushion structure 82 includes a plurality of second support bodies connected in a chain manner, the second support bodies are arranged at intervals and connected in sequence through movable joints, thereby forming a chain structure that can be curled and deformed, and the second support bodies are in the shape of long strips, and the length direction is parallel to the axis of the first support body 5. In other embodiments, in order to support the first part of the display screen 4 in the extended state, a plurality of slats distributed at equal intervals may be fixedly connected to the side of the first part of the display screen 4 facing away from the display surface, the thickness direction of the slats is perpendicular to the display surface of the display screen 4, and the length direction of the slats is parallel to the axis of the first support body 5. The width of the slats is less than the first preset value, and the spacing between the slats is less than the second preset value, so that the grate structure composed of these slats can curl and deform with the first part, and can also form support at any position of the display surface of the first part of the display screen 4 when the user's finger touches and presses, so as to prevent the first part of the display screen 4 from being excessively concave when the user touches and presses.

[0048] like Figure 3As shown, in some embodiments, the second rotating element may include two supporting parts 32 arranged opposite to each other, and the first rotating element 31 is located between the two supporting parts 32 and is rotatably connected to the supporting parts 32. A space for installing the first rotating element 31 is formed between the two supporting parts 32, and the two supporting parts 32 support the first rotating element 31 from both ends of the first rotating element 31. This structural form can facilitate the assembly of the first rotating element 31 and the second rotating element of the rotating shaft device 3, and the relative rotation of the first rotating element 31 and the second rotating element is relatively stable and reliable. The first rotating element 31 can be set as an integral structure with the first sub-body 11, and the supporting part 32 can be set as an integral structure with the second body 2, so that the overall structural strength of the electronic device can be improved. In other embodiments, the second rotating element may include a sleeve that is sleeve-connected to a part of the first rotating element 31, and the sleeve is rotatably matched with the first rotating element 31, so that the first rotating element 31 and the second rotating element can rotate relative to each other. The part of the first rotating element 31 connected to the sleeve can be a part of the two ends of the first rotating element 31. In other embodiments, the second rotating element may include a rotating shaft axially penetrating the first rotating element 31 , and the rotating shaft is rotatably connected to the first rotating element 31 , so that the first rotating element 31 and the second rotating element can rotate relative to each other.

[0049] like Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, a wiring groove 321 may be provided on at least one support portion 32, and a wire hole 311 communicating with the accommodation space may be provided at the center position of the end of the first rotating element 31. The cable 7 may pass through the wire hole 311 and then enter the interior of the second body 2 through the wiring groove 321, thereby realizing the electrical connection between the components in the accommodation space of the hinge device 3 and the components inside the second body 2. For example, the second body 2 may be the host part of an electronic device, the motherboard of the electronic device is provided inside the second body 2, and the first part of the display screen 4 is electrically connected to the motherboard through the cable 7. In addition, when components such as a control board 6 and a power storage component 9 are provided in the accommodation space of the hinge device 3, these components may also be electrically connected to the motherboard of the electronic device through the cable 7.

[0050] In this specification, each part of the structure is described in a progressive manner, and the structure of each part focuses on the differences from the existing structure. The overall and partial structures of the electronic device can be obtained by combining the structures of the above multiple parts.
