Description

Technical Field

[0001] The present application belongs to the technical field of communication equipment, and specifically relates to an electronic device. Background Art

[0002] In order to take into account the characteristics of portability and large display area, foldable electronic devices are increasingly favored by consumers. Foldable electronic devices generally include outward-folding electronic devices and inward-folding electronic devices. When the outward-folding electronic device is in the folded state, its display screen is located on the outside and is easily bumped and scratched; while when the current inward-folding electronic device is in the folded state, the bending angle is usually only set in the middle folding part of the display screen, and the two edge parts of the display screen that are opposite and stacked are made to fit each other. This may cause the two edge parts of the display screen to be scratched or damaged due to the mixing of hard particles such as dust or sand and gravel between the two edge parts, which has a serious adverse effect on the service life of the display screen. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide an electronic device to solve the problem that the display screen of the electronic device is easily damaged and has a short service life.

[0004] The embodiment of the present application discloses an electronic device, which includes a first housing, a second housing, a display screen, a transmission component and a linkage component, wherein:

[0005] The first shell and the second shell are rotatably connected, the display screen includes a first display portion, a second display portion and a bending portion, the first display portion is connected to the second display portion through the bending portion, the first display portion is arranged on the first shell, and the second display portion is arranged on the second shell;

[0006] The linkage assembly is arranged between the first housing and the first display part, and the linkage assembly includes a first support member and a second support member, at least one of the first support member and the second support member is provided with a matching inclined surface, and the two members are movably matched through the matching inclined surface, so that the first housing and the first display part are movably matched in a first direction perpendicular to the first display part;

[0007] The first housing is provided with the transmission assembly, and the transmission assembly is used to drive the first support member to reciprocate relative to the second support member;

[0008] The electronic device has an unfolded state and a folded state. During the process of the electronic device switching from the unfolded state to the folded state, the first support member and the second support member move toward each other in the first direction to reduce the distance between the first display part and the first shell in the first direction; during the process of the electronic device switching from the folded state to the unfolded state, the first support member and the second support member move away from each other in the first direction to increase the distance between the first display part and the first shell in the first direction.

[0009] The embodiment of the present application discloses an electronic device, which includes a first shell, a second shell, a display screen, a transmission assembly and a linkage assembly, wherein the first shell and the second shell are rotatably connected, the display screen is integrally mounted on the first shell and the second shell, and the first display part and the second display part of the display screen are connected via a bending part. A linkage assembly is provided between the first shell and the first display part, and the first support member and the second support member of the linkage assembly are movably matched through matching inclined surfaces, and the transmission assembly can be used to enable the first shell and the first display part to have the ability to movably match in a first direction perpendicular to the first display part, thereby enabling the first shell and the first display part to approach and move away from each other in the first direction, and changing the spacing between the first display part and the base of the first shell.

[0010] The above-mentioned electronic device has an unfolded state and a folded state. In the unfolded state, the distance between the first display part and the base of the first shell is relatively large, so that there will not be a large height difference between the first display part and the second display part, and the first display part and the second display part can even be coplanar, which enables the display screen to provide users with a better user experience.

[0011] In the folded state, the distance between the first display unit and the base of the first shell is relatively small, so that a gap of a certain size can be formed between the first display unit and the second display unit opposite to each other, thereby further preventing dust and other particles from squeezing the first display unit and the second display unit and damaging the display screen during the folding process of the electronic device and when it is in the folded state.

[0012] In addition, in the electronic device disclosed in the embodiment of the present application, as the electronic device is folded, the first display portion has the ability to move toward the base close to the first shell, thereby expanding the accommodating space of the display screen and preventing the bent portion of the display screen from being squeezed during the folding process.

[0025] 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 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.

[0026] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0027] The folding mechanism and the electronic device provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0028] like Figures 1 to 5 As shown, an embodiment of the present application discloses an electronic device, which is a foldable electronic device and includes a first shell 110 , a second shell 120 , a display screen 200 , a transmission component and a linkage component 400 .

[0029] Among them, the first shell 110 and the second shell 120 are rotatably connected, so that the electronic device has the ability to fold and unfold. Specifically, the first shell 110 and the second shell 120 can be provided with the ability to rotate relative to each other by setting a hinge mechanism. The first shell 110 and the second shell 120 are the outer shell parts of the electronic device, and both can be made of hard materials such as plastic or metal to enhance the structural strength of the two. At the same time, the first shell 110 and the second shell 120 can also be used as the installation basis of other components in the electronic device. For example, the display screen 200, the transmission assembly and the linkage assembly 400 can be directly or indirectly installed on the first shell 110 and the second shell 120. The structures of the first shell 110 and the second shell 120 can be symmetrical to each other, or the first shell 110 and the second shell 120 can also be two devices with different structures. As for the specific shape and size parameters of the first shell 110 and the second shell 120, this article does not limit them.

[0030] More specifically, if Figure 2As shown, the first shell 110 includes a base 111 and a frame 112, and the frame 112 is connected to one side of the base 111, so that the two can form a chamber, and the chamber can accommodate a part of the display screen 200. Specifically, the base 111 can be a plate-shaped structural member, and the frame 112 can be an annular structural member. The frame 112 is connected to a side surface of the base 111. The sizes of the base 111 and the frame 112 can be determined according to actual needs and are not limited here. Based on this, the distance between the first display unit 210 and the first shell 110 mentioned below in the first direction can specifically be the distance between the first display unit 210 and the base 111 in the first direction.

[0031] like Figure 3 As shown, the display screen 200 includes a first display portion 210, a second display portion 220 and a bending portion 230. The first display portion 210 is connected to the second display portion 220 via the bending portion 230. The bending portion 230 is a flexible structural member, that is, the bending portion 230 has the ability to deform. On this basis, the first display portion 210 and the second display portion 220 can rotate relative to each other using the bending portion 230. Specifically, the first display portion 210 and the second display portion 220 can be hard screens, and the two can be connected to opposite sides of the bending portion 230 respectively.

[0032] At the same time, the first display unit 210 is arranged on the first shell 110, and the second display unit 220 is arranged on the second shell 120, so that the first shell 110 and the second shell 120 can provide a position restriction function within a certain range for the display screen 200. In addition, in the following, since the first display unit 210 has the ability to move relative to the first shell 110, other limiting structures can also be arranged on the first shell 110 to provide auxiliary functions for the connection reliability between the first display unit 210 and the first shell 110, so as to ensure that the first shell 110 and the first display unit 210 have strong connection stability. Optionally, a fixed connection relationship is formed between the second display unit 220 and the second shell 120, or the connection relationship between the second display unit 220 and the second shell 120 can be designed in accordance with the connection relationship between the first display unit 210 and the first shell 110, which is not limited here.

[0033] like Figure 3 and Figure 4As shown, the linkage assembly 400 includes a first support member 410 and a second support member 420, at least one of which is provided with a matching inclined surface 411, and the two are movably matched through the matching inclined surface 411. Specifically, by connecting the first support member 410 and the second support member 420 with the matching inclined surface 411, the two have the ability to move relative to each other along the matching inclined surface 411, and it can be considered that the first support member 410 and the second support member 420 have the ability to move along the directions where the two vertical components of their motion vectors are located, so that the two components connected to each other by the first support member 410 and the second support member 420 have the ability to approach and move away from each other along the directions where the aforementioned vertical components are located.

[0034] Based on this, the aforementioned linkage assembly 400 is arranged between the first housing 110 and the first display unit 210. Optionally, one of the first housing 110 and the first display unit 210 may be fixedly connected with a first support member 410 (or a second support member 420), and the second support member 420 (or the first support member 410) may be connected to the transmission assembly, so that under the action of the transmission assembly, the first support member 410 and the second support member 420 have the ability to move relative to each other along the matching inclined surface 411, thereby driving the first housing 110 and the first display unit 210 to move relative to each other along the first direction, and by limiting the parameters such as the setting position of the transmission assembly and the assembly method of the linkage assembly 400, it can be ensured that the relative movement direction of the first housing 110 and the first display unit 210 is perpendicular to the first display unit 210. More specifically, the first direction is the direction of a vertical component of the vector of the relative movement of the first support member 410 and the second support member 420, and the first direction is perpendicular to the display unit 210. Correspondingly, the direction in which the transmission assembly drives the first support member 410 to move is the direction of another vertical component corresponding to the aforementioned vector, which can be recorded as a second direction, and the second direction is parallel to the first display portion 210 .

[0035] Optionally, the linkage assembly 400 is disposed between the frame 112 of the first housing 110 and the first display portion 210. In this case, the transmission assembly can also be disposed between the frame 112 of the first housing 110 and the first display portion 210, and the first support member 410 and the second support member 420 are distributed in a direction parallel to the first display surface of the first display portion 110. Under the action of the matching inclined surface 411, the first display portion 210 and the base 111 of the first housing 110 can be made to move relative to each other in a direction perpendicular to the first display portion 210.

[0036] In order to further reduce the size of the gap between the first display portion 210 and the first shell 110 and reduce the probability of foreign matter such as dust entering the interior of the electronic device, the transmission assembly and the linkage assembly 400 can be arranged between the first display portion 210 and the base 111 of the first shell 110. In this case, the first support member 410 and the second support member 420 in the linkage assembly 400 are distributed along a direction perpendicular to the first display portion 210, or in other words, along the thickness direction of the first display portion 210. Then, under the action of the matching inclined surface 411, the base 111 of the first shell 110 and the first display portion 210 can be driven by the transmission assembly to ensure relative movement along the thickness direction of the first display portion 210.

[0037] More specifically, if Figure 3 As shown, the first support member 410 is connected to the transmission assembly, and the end of the second support member 420 facing away from the matching bevel 411 is connected to the first display part 210. The transmission assembly drives the first support member 410 to move in a direction outside the matching bevel 411 in a thickness direction perpendicular to the first display part 210, thereby increasing or decreasing the distance between the ends of the first support member 410 and the second support member 420 facing away from each other, that is, the distance between the base 111 of the first shell 110 and the first display part 210.

[0038] The first housing 110 is provided with the above-mentioned transmission assembly. Specifically, the transmission assembly can be a driving motor, a cylinder or a hydraulic cylinder. By making the transmission assembly drive one of the first support member 410 and the second support member 420 to move linearly, the first display portion 210 and the first housing 110 can be moved closer to or farther from each other. Of course, the transmission assembly can also be other structural parts, and the transmission assembly can use energy such as electricity as a power source, or the transmission assembly can also use the force provided by the user as a power source, that is, the transmission assembly can be a manual drive device.

[0039] The electronic device has an unfolded state and a folded state. When the electronic device is in the unfolded state, the display surface of the first display unit 210 and the display surface of the second display unit 220 are coplanar, that is, the display screen 200 and the electronic device are both in the unfolded state. In addition, when the electronic device switches between the unfolded state and the folded state in accordance with the above structure and connection relationship, the distance between the first display unit 210 and the base 111 of the first housing 110 in the first direction is variable.

[0040] In detail, during the process of the electronic device switching from the unfolded state to the folded state, the first support member 410 and the second support member 420 can move toward each other in the first direction to reduce the distance between the first display portion 110 and the base of the first shell 110 in the first direction, so that when the electronic device is in the folded state, a certain gap is generated between the first display portion and the second display portion to prevent the two from squeezing each other, and to prevent foreign objects from being present between the two and damaging the display screen. At the same time, during the process of the electronic device switching from the folded state to the unfolded state, the first support member 410 and the second support member 420 can move away from each other in the first direction to increase the distance between the first display portion 210 and the base 111 of the first shell 110 in the first direction, so that when the electronic device is in the unfolded state, each position on the display screen of the electronic device has a relatively good display effect, and the consistency of the display screen is relatively good.

[0041] More specifically, when the electronic device is in the unfolded state, the display surface of the first display portion 210 is flush with the first surface of the frame 112 that is disposed away from the base portion 111, or the display surface of the first display portion 210 is located on the side of the aforementioned first surface that is away from the base portion 111 along the thickness direction of the first display portion 210, that is, at least a portion of the first display portion 210 is located outside the area surrounded by the frame 112. When the electronic device is in the unfolded state, by forming the above relationship between the first display portion 210 and the frame 112, the display effect of the first display portion 210 and the feel of the electronic device can be made relatively good.

[0042] When the electronic device is in the folded state, the first display portion 210 and the second display portion 220 are stacked, that is, the display screen 200 and the electronic device are both in the folded state. At the same time, when the electronic device is in the folded state, the frame 112 of the first housing 110 is in contact with the second housing 120, which minimizes the size of the gap between the two opposite parts of the electronic device in the folded state, and prevents external dust or sand and other particles from entering the area between the first display portion 210 and the second display portion 220.

[0043] Furthermore, when the electronic device is in the folded state, along the thickness direction of the first display portion 210, the display surface of the first display portion 210 is located on the side of the aforementioned first surface of the frame 112 close to the base portion 111 along the thickness direction of the first display portion 210. That is, in the process of the electronic device switching from the unfolded state to the folded state, the first display portion 210 can approach the base portion 111 of the first display portion 210, so that the display surface of the first display portion 210 moves from a position flush with the aforementioned surface of the frame 112 (or located on the side of the aforementioned surface of the frame 112 away from the base portion 111) to a direction close to the base portion 111, and then when the electronic device is in the folded state, the display surface of the first display portion 210 is located on the side of the aforementioned surface of the frame 112 close to the base portion 111.

[0044] In the case of adopting the above technical solution, the electronic device in the folded state (i.e., the folded state) can use the linkage assembly 400 to enable the first display portion 210 to have the ability to be spaced apart from the second display portion 220. In addition, the size range of the relative movement between the first display portion 210 and the first shell 110 can be determined according to the relative position relationship and corresponding size of the second display portion 220 and the second shell 120 in the thickness direction of the second display portion 220, so as to ensure that when the electronic device is in the folded state, the first display portion 210 can be spaced apart from the second display portion 220 in the thickness direction of the first display portion 210.

[0045] The embodiment of the present application discloses an electronic device, which includes a first housing 110, a second housing 120, a display screen 200, a transmission assembly and a linkage assembly 400. The first housing 110 and the second housing 120 are rotatably connected, the display screen 200 is integrally mounted on the first housing 110 and the second housing 120, and the first display portion 210 and the second display portion 220 of the display screen 200 are connected via a bending portion 230. A linkage assembly 400 is provided between the first housing 110 and the first display portion 210, and the first support member 410 and the second support member 420 of the linkage assembly 400 are movably matched through a matching inclined surface 411. The transmission assembly can enable the first housing 110 and the first display portion 210 to have the ability to movably match in a first direction perpendicular to the first display portion 210, thereby enabling the first housing 110 and the first display portion 210 to approach and move away from each other in the first direction, and changing the distance between the first display portion 210 and the base portion 111 of the first housing 110.

[0046] The above-mentioned electronic device has an unfolded state and a folded state. In the unfolded state, the distance between the first display unit 210 and the base 111 of the first shell 110 is relatively large, so that there will not be a large height difference between the first display unit 210 and the second display unit 220, and the first display unit 210 and the second display unit 220 can even be coplanar, which allows the display screen to provide users with a better user experience.

[0047] In the folded state, the distance between the first display unit 210 and the base 111 of the first shell 110 is relatively small, so that a gap of a certain size can be formed between the first display unit 210 and the second display unit 220 relative to each other, thereby further preventing dust and other particles from being squeezed against the first display unit 210 and the second display unit 220 and damaging the display screen 200 during the folding process of the electronic device and when it is in the folded state.

[0048] In addition, in the electronic device disclosed in the embodiment of the present application, as the electronic device is folded, the first display portion 210 has the ability to move toward the base 111 close to the first shell 110, thereby expanding the accommodating space of the display screen 200 and preventing the bent portion 230 of the display screen 200 from being squeezed during the folding process.

[0049] As described above, the rotational coordination relationship between the first shell 110 and the second shell 120 can be assisted by an additional hinge mechanism, that is, the transmission component may not participate in the rotation process between the first shell 110 and the second shell 120, but during the relative rotation of the first shell 110 and the second shell 120, the transmission component can generate a driving action accordingly, cooperate with the folding and unfolding process of the first shell 110 and the second shell 120, and correspondingly make the first display part 210 move closer to or away from the base 111 of the first shell 110.

[0050] In another embodiment of the present application, in order to further reduce the total amount of components in the electronic device and improve the reuse capability of the components, optionally, as Figures 1 to 3 As shown, the transmission assembly includes a first gear 310 and a second gear 320, wherein the first gear 310 is rotatably mounted on the first shell 110, and the second gear 320 is rotatably mounted on the second shell 120, ensuring that the first gear 310 has the ability to rotate relative to the first shell 110, and ensuring that the second gear 320 has the ability to rotate relative to the second shell 120.

[0051] At the same time, the first gear 310 and the second gear 320 are meshed, so that under the transmission action of the first gear 310 and the second gear 320, the first housing 110 and the second housing 120 have the ability to rotate relative to each other. Conversely, during the relative rotation of the first housing 110 and the second housing 120, the first gear 310 and the second gear 320 can also be driven to rotate relative to each other. In addition, by making the tooth widths of the first gear 310 and the second gear 320 relatively large, the rotation stability between the first housing 110 and the second housing 120 can be improved. Alternatively, the number of the first gear 310 and the second gear 320 can be multiple, and the multiple first gears 310 can be distributed along the axial direction of the first gear 310. When the multiple second gears 320 are meshed with the multiple first gears 310 one by one, the stability of the rotational matching relationship between the first housing 110 and the second housing 120 can also be improved.

[0052] In this embodiment, if Figure 2 As shown, the transmission assembly can also include a first push member 370, a first end of the first push member 370 is connected to the first support member 410, and a second end of the first push member 370 cooperates with the first gear 310, so that when the first gear 310 rotates relative to the first shell 110, the first push member 370 can also be driven to rotate synchronously with the first gear 310 to change the size of the first push member 370 in the second direction mentioned above. The aforementioned second direction is the driving direction, which is perpendicular to the first direction, and the two are two vertical components of the direction of relative movement of the first support member 410 and the second support member 420. The second direction can be specifically Figure 3 In the direction X. At the same time, since the component of the first push member 370 in the aforementioned driving direction changes with the rotation of the first gear 310, the distance between the first support member 410 and the first gear 310 in the aforementioned driving direction can be changed during the rotation of the first gear 310 relative to the first housing 110, so as to achieve the purpose of driving the first support member 410 to move relative to the second support member 420 along the matching inclined surface 411.

[0053] More specifically, in the case of adopting the above technical solution, affected by the relative rotation direction between the first housing 110 and the second housing 120, the rotation direction of the first gear 310 includes two directions, positive and negative, and then in the process of relative rotation between the first housing 110 and the second housing 120, the first gear 310 and the second gear 320 reciprocate, so that the first push member 370 can reciprocate with the first gear 310, and drive the first support member 410 to move, and then drive the second support member 420 to reciprocate along the first direction relative to the base 111 of the first housing 110. Of course, the first gear 310 can also be equipped with a drive motor, etc., so that the first gear 310 has the ability to rotate automatically, or the first gear 310 can be driven in the process of the user manually driving the first housing 110 and the second housing 120 to rotate relative to each other.

[0054] In the above technical solution, the first push member 370 and the first support member 410 can be relatively fixed along the aforementioned driving direction, so that under the action of the first gear 310, the first push member 370 can apply both thrust and tension to the first support member 410. Of course, during the rotation of the first gear 310, the end of the first push member 370 that is away from the first gear 310 will move relative to the first support member 410 along the thickness direction of the first display portion 210. Therefore, by providing a slideway or the like, the first push member 370 and the first support member 410 can be relatively fixed in the aforementioned driving direction while being able to move relative to each other in the first direction.

[0055] In the case where the transmission assembly includes the first gear 310 and the first push member 370, in another embodiment of the present application, the first end of the first push member 370 is in abutment with the first support member 410, that is, the first push member 370 can apply a thrust to the first support member 410, but the first push member 370 cannot apply a pulling force to the first support member 410. In the case of adopting this technical solution, the structure of the first push member 370 is relatively simple, and there is no need to design a corresponding slide groove structure for the active track between the first push member 370 and the first support member 410, which can also reduce the difficulty of assembling the first push member 370 and the first support member 410.

[0056] Of course, in this embodiment, since the first push member 370 cannot provide a pulling force to the first support member 410, the first support member 410 cannot be reset. Figure 1 and Figure 3As shown, the transmission assembly disclosed in the embodiment of the present application may also include an elastic reset member 390, which is elastically connected to the first support member 410, so that the first push member 370 applies a force to the first support member 410, and at the same time as changing the relative position between the first support member 410 and the first shell 110, a force can be applied to the elastic reset member 390 to put the elastic reset member 390 into a stretched or compressed state, and then after the first push member 370 removes the force acting on the first support member 410, the first support member 410 can be reset under the elastic action of the elastic reset member 390, thereby ensuring that the first support member 410 has the ability to reciprocate relative to the second support member 420 along the aforementioned driving direction.

[0057] In detail, when the above technical solution is adopted, when the electronic device switches from the unfolded state to the folded state, as Figure 1 and Figure 2 As shown, the first push member 370 rotates along with the first gear 310 in the first rotation direction, pushes the first support member 410 and squeezes or stretches the elastic reset member 390 to drive the second support member 420 to move along the first direction toward the base 111 of the first shell 110.

[0058] Correspondingly, during the process of the electronic device switching from the folded state to the unfolded state, if Figure 3 As shown, the first push member 370 rotates along the second rotation direction with the first gear 310 and avoids the first support member 410. When the first push member 370 no longer applies force to the first support member 410, the elastic reset member 390 can restore the elastic deformation and drive the first support member 410 to move, thereby driving the second support member 420 to move along the first direction away from the base 111 of the first shell 110.

[0059] The first push member 370 may be a rod-shaped structural member, and one end of the first push member 370 may be directly fixed on the end surface of the first gear 310; the elastic reset member 390 may be a spring, which has relatively strong elasticity. In addition, when the electronic device is in the unfolded state and the folded state, the rotation direction of the first gear 310 is related to the inclination direction of the matching inclined surface, which is not limited here.

[0060] As described above, the first gear 310 and the second gear 320 can provide a transmission function for the rotation process between the first housing 110 and the second housing 120. Therefore, a part of the first gear 310 needs to be located outside the first housing 110, and similarly, a part of the second gear 320 also needs to be located outside the second housing 120 to ensure that the first gear 310 and the second gear 320 can form a rotation connection relationship. In this case, if the first push member 370 is directly fixed on the first gear 310, the rotation radius of the first push member 370 will be relatively large, and there will be a problem of wasting the internal space of the electronic device.

[0061] Based on this, in another embodiment of the present application, optionally, the transmission assembly further includes a third gear 330, and the third gear 330 is located between the first gear 310 and the base 111, that is, the third gear 330 can be located as a whole within the area surrounded by the frame 112 and the base 111 in the first housing 110. In addition, the third gear 330 is transmission-connected with the first gear 310, and on this basis, the first push member 370 can be fixedly connected to the third gear 330, which can greatly reduce the space occupied by the first push member 370 when rotating with the first gear 310, thereby improving the structural compactness of the electronic device and reducing the volume of the electronic device.

[0062] Specifically, the dimensions and other parameters of the first gear 310 and the third gear 330 can be determined according to actual needs, and the first gear 310 and the third gear 330 can be directly connected to each other, or can be indirectly driven by a first transmission member 350 such as a toothed belt. The first push member 370 can be fixedly connected to the third gear 330 by bonding or other means, so that when the first gear 310 drives the third gear 330 to rotate, the third gear 330 can also drive the first push member 370 to rotate synchronously.

[0063] As described above, a linkage component 400 is provided between the first display unit 210 and the first shell 110. In order to improve the stability of the relative movement between the first display unit 210 and the first shell 110, multiple linkage components 400 can be provided between the first display unit 210 and the first shell 110, so that the multiple linkage components 400 can provide support for the first display unit 210 together.

[0064] Optionally, multiple linkage components 400 are evenly distributed. Specifically, taking the first display unit 210 as a rectangular or approximately rectangular structure as an example, multiple linkage components 400 can be distributed in a determinant, thereby providing a more reliable support for the first display unit 210. Optionally, in the case where the first display unit 210 (and the first shell 110) are both rectangular or approximately rectangular structures, the corners of the first shell 110 can be provided with linkage components 400, thereby ensuring that the overall support effect of the first display unit 210 is relatively good. Of course, the linkage component 400 can be further provided at the middle position of the first shell 110 to ensure that any position on the first display unit 210 can be well supported.

[0065] In the case of adopting the above technical solution, a transmission component can be provided for each of the multiple linkage components 400 disposed between the first display unit 210 and the first housing 110. In order to reduce the number of transmission components, optionally, as Figure 1 and Figure 3 As shown, the electronic device also includes a connecting member 430, which can be a plate-like structural member. Multiple first support members 410 are fixedly connected via the connecting member 430, and by making the transmission component transmission-connected to the connecting member 430, a transmission component can be used to simultaneously drive multiple first support members 410 fixedly connected to the same connecting member 430 to move, which can also improve the movement consistency of multiple linkage components 400.

[0066] Optionally, the connecting member 430 is a rod-shaped structural member. In this case, the plurality of first supporting members 410 distributed along the aforementioned driving direction can be fixed to the connecting member 430 by bonding or other connection methods. Further, there are a plurality of connecting members 430, and the plurality of connecting members 430 are distributed along a direction perpendicular to the aforementioned driving direction and the thickness direction of the first display portion 210. Any of the plurality of connecting members 430 can provide a transmission function for the plurality of first supporting members 410 distributed along the aforementioned driving direction, thereby maximally reducing the number of transmission components and improving the consistency of the movements of the plurality of first supporting members 410.

[0067] As described above, a linkage assembly 400 is provided between the first display portion 210 and the first shell 110, and by connecting the linkage assembly 400 with the transmission assembly, the first display portion 210 and the first shell 110 have the ability to approach and move away from each other in a direction perpendicular to the first display portion 210, thereby preventing the first display portion 210 from being closely attached to the second display portion 220 when the electronic device is in a folded state.

[0068] In the case where there are multiple linkage components 400, in another embodiment of the present application, optionally, as Figure 3As shown, a linkage assembly 400 may also be provided between the second display portion 220 and the second shell 120, and similar to the linkage assembly 400 provided between the first display portion 210 and the first shell 110, by connecting the linkage assembly 400 provided between the second display portion 220 and the second shell 120 to the transmission assembly, the second display portion 220 can be driven by the transmission assembly to have the ability to move closer to or farther from the second shell 120, thereby further expanding the distance between the first display portion 210 and the second display portion 220 in the electronic device when in a folded state, thereby improving the service life of the display screen 200 of the electronic device.

[0069] Correspondingly, in the case where a linkage assembly 400 is provided between the second display portion 220 and the second housing 120, a driving device such as a driving motor can also be separately provided for the linkage assembly 400. Alternatively, in another embodiment of the present application, the linkage assembly 400 matched with the second display portion 220 can also be driven by the first gear 310 and the second gear 320 that rotate relatively. In this case, the second gear 320 is also provided with a device similar to the first push member 370, which can be specifically a second push member 380. The first end of the second push member 380 is connected to the second support member 420 in the linkage assembly 400, and the second end of the second push member 380 is matched with the second gear 320.

[0070] Furthermore, the second gear 320 is equipped with a fourth gear 340, which is disposed between the base of the second housing 120 and the second gear 320, and the fourth gear 340 is transmission-connected to the second gear 320 via the second transmission member 360, and the second push member 380 is fixedly connected to the fourth gear 340. In addition, the linkage assembly 400 corresponding to the second display portion 220 may also include an elastic reset member 390, which is similar to the assembly method of the linkage assembly 400 corresponding to the first display portion 210, and will not be repeated here.

[0071] As described above, the first display portion 210 and the second display portion 220 in the display screen 200 may be hard screens, and the two are connected as one through the bending portion 230. In order to improve the integration of the display screen 200, in another embodiment of the present application, optionally, the display screen 200 is a flexible integrated structural member, that is, the display screen 200 is a flexible screen as a whole. On this basis, the overall display effect of the display screen 200 is relatively good, and the user experience is improved.

[0072] When adopting the technical solution disclosed in this embodiment, optionally, the electronic device disclosed in the embodiment of the present application also includes a first supporting plate 130. Specifically, the first supporting plate 130 can be made of materials such as metal or plastic, and its specific size and shape can be determined according to the structure of the first display unit 210 and the first shell 110.

[0073] The first display unit 210 can be supported and fixed on the first supporting plate 130, and the first supporting plate 130 is used to provide a reliable supporting effect for the first display unit 210, thereby improving the display effect and service life of the first display unit 210. Correspondingly, when the first display unit 210 is supported on the first supporting plate 130, the linkage assembly 400 disposed between the first display unit 210 and the first shell 110 can be disposed between the first supporting plate 130 and the first shell 110, and the second support member 420 forms a fixed connection relationship with the first supporting plate 130, and then when the transmission assembly drives the first support member 410 to move, the first display unit 210 can also be moved in a direction close to or away from the base 111 through the first supporting plate 130.

[0074] Similarly, the second display unit 220 may also be equipped with a second supporting plate 140 , and the second display unit 220 may be supported and fixed on the second supporting plate 140 . The second supporting plate 140 provides a reliable supporting effect for the second display unit 220 , thereby improving the display effect and service life of the second display unit 220 .

[0075] As described above, other structures can be used to provide restrictions on the active connection relationship between the first display unit 210 and the first shell 110. For example, a slide groove can be opened on the first shell 110, and a corresponding slider can be set on the edge of the first display unit 210, so as to provide auxiliary limiting effect for the first display unit 210 and the first shell 110 by using the sliding-matching slider and the slide groove.

[0076] In another embodiment of the present application, optionally, Figure 1 and Figure 3 As shown, the electronic device further includes a guide component 500, such as Figure 5 As shown, the guide assembly 500 includes a first guide portion 510 and a second guide portion 520, the first guide portion 510 is fixedly connected to the first housing 110, the second guide portion 520 is fixedly connected to the first display portion 210, and the first guide portion 510 and the second guide portion 520 are slidably connected along the thickness direction of the first display portion 210, so that the guide assembly 500 provides a guiding and limiting function for the first display portion 210 and the first housing 110. Similarly, in the case where the second display portion 220 and the second housing 120 have a relative movement along the thickness direction of the second display portion 220, the guide assembly 500 can also be arranged between the second display portion 220 and the second housing 120. In addition, the number of the guide assembly 500 arranged between the first display portion 110 and the first housing 110 and the number of the guide assembly 500 arranged between the second display portion 220 and the second housing 120 are both multiple, so as to further improve the stability of the movement between the components.
