[0026] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present application. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present application. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present application.

[0027] The terms used herein are only for describing specific embodiments and are not intended to limit this application. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0028] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0029] When expressions such as "at least one of A, B, and C, etc." are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0030] Figure 1 The figure schematically shows a conventional electronic device 100 in which a crease exists in the bending area 111 of the display screen.

[0031] like Figure 1 As shown, when the display screen 110 is flattened, there is an obvious crease in the bending area 111 of the display screen 110 corresponding to the folding portion 120, making the display screen 110 uneven.

[0032] Conventional electronic devices 100 typically have elastic members disposed in the bending region 111 (e.g., on the back of the bending region 111) to provide elastic force to the bending region. This elastic force stretches the bending region 111, thereby maintaining a flat display screen 110. However, disposing an elastic member in the bending region 111 makes the device difficult to bend, and the elastic force provided by the elastic member in this location is unstable, resulting in a poor stretching effect on the bending region 111.

[0033] An embodiment of the present application provides an electronic device, comprising: a first body, the first body being provided with a first target part, the first target part applying a first force toward a first direction in a first target state; a second body, the second body being provided with a second target part, the second target part applying a second force toward a second direction in a second target state; a connecting device, the first body and the second body being rotatably connected through the connecting device, the electronic device having a flattened state and a bent state, and in the flattened state and the bent state, the angle between the first body and the second body is different; a display screen, comprising a first part, a second part and a bendable part, the first part being provided on the first body, and the second part being provided on the second body, the first force being applied to the first part, and the second force being applied to the second part; in the flattened state and the bent state, the first target part is in the first target state, and the second target part is in the second target state; in the flattened state, the extension direction of the second part toward the first part is the first target direction, which is the same as the first direction, and / or the extension direction of the first part toward the second part is the second target direction, which is the same as the second direction.

[0034] The electronic device provided in the embodiment of the present application can achieve the goal of keeping the bendable portion flat without affecting the flattening and bending of the electronic device, reducing the resistance of the electronic device when flattening or bending, and extending the service life of the electronic device by setting a first target part on the first body, setting a second target part on the second body, applying a first force applied by the first target part to the first part, and applying a second force applied by the second target part to the second part.

[0035] The following Figures 2 to 8 An electronic device according to an embodiment of the present application is described in detail.

[0036] Figure 2 A cross-sectional view schematically shows the internal structure of an electronic device according to an embodiment of the present application.

[0037] like Figure 2 As shown, the electronic device 200 includes: a first body 201, the first body 201 is provided with a first target member 231, the first target member 231 applies a first force toward a first direction in a first target state; a second body 202, the second body 202 is provided with a second target member 232, the second target member 232 applies a second force toward a second direction in a second target state; a connecting device 210, the first body 201 and the second body 202 are rotatably connected by the connecting device 210, the electronic device 200 has a flat state and a bent state, in which the angles between the first body 201 and the second body 202 are different; a display screen 220, including a first part The first part 221, the second part 222 and the bendable part 223, the first part 221 is arranged on the first body 201, the second part 222 is arranged on the second body 202, the first force is applied to the first part 221, and the second force is applied to the second part 222; in the flattened state and the bent state, the first target part 231 is in the first target state, and the second target part 232 is in the second target state; in the flattened state, the extension direction of the second part 222 toward the first part 221 is the first target direction, and the first target direction is the same as the first direction, and / or the extension direction of the first part 221 toward the second part 222 is the second target direction, and the second target direction is the same as the second direction.

[0038] The first body 201 and the second body 202 can be the housing of the electronic device 200, or can be other components within the electronic device that can be provided with the first target part 231 and the second target part 232. It should be noted that the embodiments of the present application do not limit the first body 201 and the second body 202, and any components that can function as the first body 201 and the second body 202 of the present application can serve as the first body 201 and the second body 202. For example, the first body 201 and the second body 202 constitute the rear housing of the electronic device 200, the first body 201 being the housing portion on the left side of the connecting device 210, and the second body 202 being the housing portion on the right side of the connecting device 210.

[0039] The first target member 231 and the second target member 232 can be elastic members disposed on the first body 201 and the second body 202, and can generate elastic deformation. The elastic member can be a single component capable of generating elastic deformation, or a combination of multiple components capable of generating elastic deformation. The first target member 231 and the second target member 232 can also be active or passive driving devices. The passive driving device can be an elastic member, etc., while the active driving device can be a piezoelectric ceramic, etc.

[0040] For example, the first target member 231 and the second target member 232 can undergo compressive deformation. The first target state and the second target state can be compressed states. In the compressed state, the first target member 231 applies a first force in a first direction, and the second target member 232 applies a second force in a second direction. The first direction can be the direction in which the first target member 231 recovers its elastic deformation, and the first force can be the force generated by the first target member 231 recovering its elastic deformation. For example, if the first target member 231 is a spring in a compressed state, the spring provides an elastic force to restore its original length. The second direction can be the direction in which the second target member 232 recovers its elastic deformation, and the second force can be the force generated by the second target member 232 recovering its elastic deformation.

[0041] The connecting device 210 can be a device that enables the first body 201 and the second body 202 to rotate about it, for example, it can be a hinge, a rotating shaft, etc. The connecting device 210 is disposed between the first body 201 and the second body 202 and can be an independent component separate from the first body 201 and the second body 202, or it can be a component integrally formed with the first body 201 and the second body 202. It should be noted that this application does not limit the structure of the connecting device 210; any component that enables the first body 201 and the second body 202 to rotate about it can serve as the connecting device 210.

[0042] The first body 201 and the second body 202 rotate around the connecting device 210, so that the electronic device 200 is in a flat state or a bent state. In the flat state, the first body 201 and the second body 202 can be in the same plane, and the angle between the first body 201 and the second body 202 can be 180 degrees. In the bent state, the angle between the first body 201 and the second body 202 can be less than 180 degrees, and as the degree of bending deepens, the angle between the first body 201 and the second body 202 can become smaller and smaller. For example, when the first body 201 and the second body 202 are in contact or when the first body 201 and the second body 202 are parallel (but not in the same plane), the angle between the first body 201 and the second body 202 can be 0 degrees.

[0043] When the electronic device 200 is bent, the display screen 220 of the electronic device 200 can be clearly divided into a bendable display portion and a flat display portion. The bendable display portion is the bendable portion 223, which forms a curved convex surface. The first portion 221 and the second portion 222 are the flat display portions. For example, when the electronic device 200 is bent, the display screen 220 of the electronic device 200 is divided into the bendable display portion and the first and second flat display portions on either side of the bendable display portion. The first portion 221 can be the first flat display portion, and the second portion 222 can be the second flat display portion.

[0044] For example, the first portion 221 may be located at a position in the display screen 200 corresponding to the first body 201, the orthographic projection area of ​​the first portion 221 toward the first body 201 is located within the first body 201, and the first body 201 and the first portion 221 are located on a first side of the connecting device 210. The second portion 222 may be located at a position in the display screen 200 corresponding to the second body 202, the orthographic projection area of ​​the second portion 222 toward the second body 202 is located within the second body 202, and the second body 222 and the second portion 202 are located on a second side of the connecting device 210. The first side and the second side of the connecting device 210 indicate positions in different directions of the connecting device 210, and do not mean that the first side of the connecting device 210 and the second side of the connecting device 210 are opposite to each other.

[0045] According to an embodiment of the present application, in the bent state, the bendable portion 223 is located between the first portion 221 and the second portion 222 , and the orientation of the first portion 221 is opposite to that of the second portion 222 .

[0046] When the electronic device 200 is folded, the first and second bodies 201, 202 can rotate inward along the connecting means 210, with the display screen 220 displaying outward. The average distance between the first and second bodies 201, 202 is smaller than the average distance between the first and second portions 221, 222, and the first and second bodies 201, 202 are positioned between the first and second portions 221, 222. As the degree of folding deepens, the degree of convexity of the bendable portion 223 increases. When the electronic device 200 is fully folded, the first and second bodies 201, 202 touch or are parallel to (but not coplanar with) the second body 202, and the bendable portion 223 forms a curved, convex surface. When viewing the electronic device 200, the first and second portions 221, 222, and bendable portion 223 are visible, with the first and second bodies 201, 202 barely visible, or only visible at the boundary between them. This is because when the display screen 220 folds outward, it bends along the surface of the housing, with the display screen 220 visible on the outside. For example, when the electronic device 200 is fully folded, the entire display screen 220 is visible on the outside of the device. On the side of the electronic device 200 (the surface connecting the display screen 220 and the housing; the display screen 220, the housing, and the side surface constitute the outer surface of the electronic device 200), the boundary connecting the housing and the display screen 220 is visible, while the housing opposite the flat display screen is not visible. In other words, the back of the electronic device 200 (the display screen is the front) is not visible.

[0047] By folding the display screen 220 of the electronic device 200 outward, the user can see more display content without unfolding the electronic device 200, saving operation steps and improving user experience.

[0048] In the first target state, a first force in a first direction applied by the first target element 231 is applied to the first portion 221. For example, the first force can be transmitted to the first portion 221 via the first middleware 241 in the electronic device 200. In the second target state, a second force in a second direction applied by the second target element 231 is applied to the second portion 222. For example, the second force can be transmitted to the second portion 222 via the second middleware 242 in the electronic device 200. The application of the first force to the first portion 221 and the application of the second force to the second portion 222 will be described in detail below in conjunction with the first middleware 241 and the second middleware 242.

[0049] According to an embodiment of the present application, regardless of whether the electronic device 200 is in a flattened state or a bent state, the states of the first target member 231 and the second target member 232 remain unchanged: the first target member 231 is always in the first target state, and the second target member 232 is always in the second target state. For example, in both the flattened state and the bent state, the first target member 231 and / or the second target member 232 are always in a compressed state. In practice, the degree of deformation of the first target member 231 in the flattened state varies compared to the bent state, resulting in different magnitudes of the first applied force in the flattened state and the bent state, and / or the degree of deformation of the second target member 232 varies, resulting in different magnitudes of the second applied force in the flattened state and the bent state.

[0050] When the electronic device 200 is in a flattened state, the extension direction of the second part 222 toward the first part 221 is the first target direction, and the first target direction is the direction from the bendable part 223 to the first part 221. The first target direction is the same as the first direction. Therefore, when the electronic device 200 is in a flattened state, the direction of the first force applied by the first target part 231 in the first target state is also the direction from the bendable part 223 to the first part 221. That is to say, the first target part 231 can provide a thrust away from the connecting device 210 for the first part 221, and the first part 221 stretches the bendable part 223, thereby having the effect of stretching the fold of the bendable part 223 from the bendable part 223 toward the first part 221.

[0051] Since the first target member 231 is in the first target state in both the flattened and bent states of the electronic device 200, in the flattened state, the direction of the first force is from the bendable portion 223 toward the first portion 221. Therefore, in the bent state, the direction of the first force is also from the bendable portion 223 toward the first portion 221. In other words, whether in the flattened or bent state, the direction of the first force is always from the bendable portion 223 toward the first portion 221, thereby providing a thrust to the first portion 221 away from the connecting device 210. For the bendable portion 223, the first force acts to provide a stretching effect on the crease area. For example, when flattened, the first target member 231 is in a compressed state, and an elastic restoring force acts on the first portion 221 along the direction from the bendable portion 223 to the first portion 221. When bent, the first target member 231 is still in a compressed state, and an elastic restoring force acts on the first portion 221 along the direction from the bendable portion 223 to the first portion 221. The elastic restoring force exerted by the first target member 231 always provides a tensile effect on the bendable portion 223. When the electronic device 200 is assembled, the first target member 231 can be set to the first target state. When the electronic device 200 is flattened or bent, the first target member 231 always remains in the first target state.

[0052] When the electronic device 200 is in a flattened state, the extension direction of the first part 221 toward the second part 222 is the second target direction, and the second target direction is the direction from the bendable portion 223 to the second part 222. The second target direction is the same as the second direction. Therefore, when the electronic device 200 is in a flattened state, the direction of the second force applied by the second target part 232 in the second target state is also in the direction from the bendable portion 223 to the second part 222. That is, the second target part 232 provides a thrust for the second part 222 away from the connecting device 210, and the second part 222 stretches the bendable portion 223, thereby having the effect of stretching the fold of the bendable portion 223 from the bendable portion 223 to the second part 222.

[0053] Since the second target member 232 is in the second target state in both the flattened state and the bent state of the electronic device 200, in the flattened state, the direction of the second force is from the bendable portion 223 to the second portion 222. Therefore, in the bent state, the direction of the second force is also from the bendable portion 223 to the second portion 222. In other words, whether in the flattened state or the bent state, the direction of the second force is always from the bendable portion 223 to the second portion 222, thereby providing a thrust to the second portion 222 away from the connecting device 210. For the bendable portion 223, the second force acts to provide a stretching effect on the crease area. For example, when flattened, the second target element 231 is in a compressed state, and an elastic restoring force acts on the second portion 222 along the direction from the bendable portion 223 to the second portion 222. When bent, the second target element 232 is still in a compressed state, and an elastic restoring force acts on the second portion 222 along the direction from the bendable portion 223 to the second portion 222. The elastic restoring force exerted by the second target element 232 always provides a stretching effect on the bendable portion 223. When the electronic device 200 is assembled, the second target element 232 can be set to the second target state. When the electronic device 200 is flattened or bent, the second target element 232 always remains in the second target state.

[0054] The electronic device 200 provided in the embodiment of the present application has the first target part 231 and the second target part 232 respectively arranged on the first body 201 and the second body 202. The bendable portion 223 is stretched by the first force of the first target part 231 and the second force of the second target part 232, so that the bendable portion 223 can be kept flat without affecting the flattening and bending of the electronic device 200, thereby reducing the resistance of the electronic device 200 when flattening or bending, and extending the service life of the electronic device 200.

[0055] According to an embodiment of the present application, the electronic device 200 may be any electronic device having a flexible display and supporting web browsing, including but not limited to a smart phone, a tablet computer, a laptop computer, and the like.

[0056] According to an embodiment of the present application, in the flattened state, the first target part 231 is located in the connecting device 210 along the second target direction toward the positive projection area of ​​the connecting device 210, and the second target part 232 is located in the connecting device 210 along the first target direction toward the positive projection area of ​​the connecting device 210.

[0057] In the flattened state, the direction in which the second portion 222 extends toward the first portion 221 is the first target direction, and the direction in which the first portion 221 extends toward the second portion 222 is the second target direction. In other words, both the first target direction and the second target direction are parallel to the flattened display screen 220. The first target member 231 is located within the connecting device 210 along the second target direction, with its orthogonal projection toward the connecting device 210. The second target member 232 is located within the connecting device 210 along the first target direction, with its orthogonal projection toward the connecting device 210. Therefore, neither the first target member 231 nor the second target member 232 is located between the connecting device 210 and the bendable portion 223. The first target member 231 and the second target member 232 do not hinder the bending of the bendable portion 223, nor do they increase the thickness of the bendable portion 223.

[0058] By setting the first target part 231 on the first body 201 and the second target part 232 on the second body 202, the first target part 231 and the second target part 232 are prevented from appearing in the range corresponding to the bendable portion 223 and the connecting device 210, thereby avoiding affecting the bending speed and bending effect of the electronic device 200 and preventing the electronic device 200 from being unable to bend after long-term use.

[0059] According to an embodiment of the present application, the electronic device 200 is selected from at least one of the following combinations: in the flattened state, the first force applied by the first target part 231 in the first target state is a first value, and in the bent state, the first force applied by the first target part 231 in the first target state is a second value, and the first value is less than the second value; in the flattened state, the second force applied by the second target part 232 in the second target state is a third value, and in the bent state, the second force applied by the second target part 232 in the second target state is a fourth value, and the third value is less than the fourth value.

[0060] For example, in a bent state where the angle between the first body 201 and the second body 202 is 0 degrees, the bendable portion 223 of the display screen 220 is flattened, leaving no room for the display screen on the bendable portion 223 to stretch. The first force applied to the first portion 221 does not cause the display screen on the bendable portion 223 to further flatten, and the first target element 231 does not recover its elastic deformation. Therefore, the first force is the second value. In the flattened state, the bendable portion 223 of the display screen 220 includes a crease. The first force applied to the first portion 221 causes the display screen on the bendable portion 223 to further flatten, causing the first portion 221 to move in the first direction. The first target element 231 recovers some of its deformation, and the first force is the first value. Because the elastic deformation of the first target element 231 when flattened is less than that when bent, and the first target element 231 is always in the first target state (e.g., compressed) in both the flattened and bent states, the first value is less than the second value.

[0061] In the flattened state, a first force is applied to the first part 221 along a first direction, and the first part 221 drives the bendable part 223. The crease of the bendable part 223 provides a stretching space for the display screen 220. The crease is flattened under the stretching of the first part 221, and the first part 221 moves along the first direction, so that the first target part 231 in the first target state can restore part of the deformation, so that the first force provided by the first target part 231 in the flattened state is smaller than the first force provided by the first target part 231 in the bent state.

[0062] For example, in a bent state where the angle between the first body 201 and the second body 202 is 0 degrees, the bendable portion 223 of the display screen 220 is flattened, leaving no room for the display screen on the bendable portion 223 to stretch. The second force applied to the second portion 222 does not cause the display screen on the bendable portion 223 to further flatten, and the second target element 232 does not recover its elastic deformation. Therefore, the second force has a fourth value. In an unfolded state, the bendable portion 223 of the display screen 220 includes a crease. The second force applied to the second portion 222 causes the display screen on the bendable portion 223 to further flatten, causing the second portion 222 to move in the second direction, partially recovering the second target element 232. Therefore, the second force has a third value. Because the elastic deformation of the second target element 232 when flattened is less than that when bent, and the second target element 232 remains in the second target state (e.g., compressed) in both the flattened and folded states, the third value is less than the fourth value.

[0063] In the flattened state, a second force can be applied to the second part 222 along the second direction, and the second part 222 can drive the bendable part 223. The crease of the bendable part 223 provides a stretching space for the display screen 220. The crease is flattened under the stretching of the second part 222, and the second part 222 can move along the second direction, so that the second target part 232 in the second target state can restore part of the deformation, so that the second force provided by the second target part 232 in the flattened state is smaller than the second force provided by the second target part 232 in the bent state.

[0064] According to an embodiment of the present application, the force applied by the target part in the flattened state is smaller than the force applied by the target part in the bent state, thereby achieving that the bendable portion 223 is stretched in the flattened state and the crease area is flattened.

[0065] According to an embodiment of the present application, the electronic device 200 is selected from at least one of the following combinations: the first body 201 is provided with a first middle piece 241, the first end of the first middle piece 241 is slidingly connected to the first body 201, and the second end of the first middle piece 241 is connected to the first part 221, wherein the first target piece 231 is provided between the first middle piece 241 and the connecting device 210, the first target piece 231 is in contact with the first middle piece 241, and the first force is applied to the first part 221 through the first middle piece 241; the second body 202 is provided with a second middle piece 242, the first end of the second middle piece 242 is slidingly connected to the second body 202, and the second end of the second middle piece 242 is connected to the second part 222, wherein the second target piece 232 is provided between the second middle piece 242 and the connecting device 210, the second target piece 232 is in contact with the second middle piece 242, and the second force is applied to the second part 222 through the second middle piece 242.

[0066] According to an embodiment of the present application, the material of the first middle piece 241 and / or the second middle piece 242 includes at least one of the following combinations: magnesium alloy or magnesium-aluminum alloy.

[0067] Since magnesium alloy or magnesium-aluminum alloy has a relatively low density, using magnesium alloy or magnesium-aluminum alloy to make the first intermediate piece 241 and / or the second intermediate piece 242 is beneficial to reducing the weight of the electronic device 200 and improving the portability of the electronic device 200 .

[0068] Reference Figure 2The first middle piece 241 is arranged on the first body 201, the first end of the first middle piece 241 is slidingly connected to the first body 201, the second end of the first middle piece 241 is connected to the first part 221, and the first end and the second end of the first middle piece 241 are located in two opposite directions of the first middle piece 231. For example, with the first body 201 as the horizontal plane, the first end is the lower end of the first middle piece 241, and the second end is the upper end of the first middle piece 242.

[0069] The first target member 231 is disposed between the first intermediate member 241 and the connecting device 210. The direction of the line connecting the first target member 231 and the connecting device 210 intersects (e.g., is perpendicular to) the direction of the line connecting the first portion 221 and the first body 201. The first target member 231 contacts the third end (not the first end, not the second end) of the first intermediate member 241. For example, referring to Figure 2 , an end of the first target member 231 away from the connecting device 210 contacts an end of the first intermediate member 241 close to the connecting device 210 .

[0070] Because the first target member 231 is in contact with the first intermediate member 241, the first target member 231 applies a first force in a first direction to the first intermediate member 241 in the first target state. Furthermore, because the second end of the first intermediate member 241 is connected to the first portion 221 and the first end of the first intermediate member 241 is slidably connected to the first body 201, the first intermediate member 241 slides relative to the first body 201. The first force applied to the first intermediate member 241 is transmitted to the first portion 221 via the first intermediate member 241, effectively applying the first force to the first portion 221.

[0071] Reference Figure 2 The second middle piece 242 is arranged on the second body 202, the first end of the second middle piece 242 is slidingly connected to the second body 202, the second end of the second middle piece 242 is connected to the second part 222, and the first end and the second end of the second middle piece 242 are located in two opposite directions of the second middle piece 242. For example, with the second body 202 as the horizontal plane, the first end is the lower end of the second middle piece 242, and the second end is the upper end of the second middle piece 242.

[0072] The second target member 232 is disposed between the second intermediate member 242 and the connecting device 210. The direction of the line connecting the second target member 232 and the connecting device 210 intersects (e.g., is perpendicular to) the direction of the line connecting the second portion 222 and the second body 202. The second target member 232 contacts the third end (not the first end, not the second end) of the second intermediate member 242. For example, referring to Figure 2 , an end of the second target member 232 away from the connecting device 210 contacts an end of the second intermediate member 242 close to the connecting device.

[0073] Because the second target member 232 is in contact with the second intermediate member 242, the second target member 232 applies a second force in the second direction to the second intermediate member 242 in the second target state. Furthermore, because the second end of the second intermediate member 242 is connected to the second portion 222 and the first end of the second intermediate member 242 is slidably connected to the second body 202, the second intermediate member 242 slides relative to the second body 202, and the second force applied to the second intermediate member 242 is transmitted to the second portion 222 via the second intermediate member 242, which is equivalent to the second force being applied to the second portion 222.

[0074] The first intermediate member 241 transmits a first force to the first portion 221, and the second intermediate member 242 transmits a second force to the second portion 222, thereby stretching the bendable portion 223 and flattening the fold area. The first intermediate member 241 is slidably connected to the first body 201, and the second intermediate member 242 is slidably connected to the second body 202. The first intermediate member 241 can move in a first direction, and / or the second intermediate member 242 can move in a second direction, thereby stretching the display portion 220 outward and flattening the fold area.

[0075] According to an embodiment of the present application, the first middle piece 241 is slidingly connected to the first body 201 through the first connecting part 251, and the resistance of relative sliding between the first connecting part 251 and the first body 201 is smaller than the resistance of relative sliding between the first middle piece 241 and the first body 201. The second middle piece 242 is slidingly connected to the second body 202 through the second connecting part 252, and the resistance of relative sliding between the second connecting part 252 and the second body 202 is smaller than the resistance of relative sliding between the second middle piece 242 and the second body 202.

[0076] For example, because the resistance to relative sliding between the first intermediate member 241 and the first body 201 is relatively large, a first connecting member 251 may be provided in the area where the first intermediate member 241 contacts the first body 201. The provided first connecting member 251 must satisfy the following requirements: the resistance to relative sliding between the first connecting member 251 and the first body 201 is less than the resistance to relative sliding between the first intermediate member 241 and the first body 201. For example, the first connecting member 251 may be provided below the first intermediate member 241. When the first force applied by the first target member 231 causes the first intermediate member 241 to slide relative to the first body 201, the relative position between the first intermediate member 241 and the first connecting member 251 remains unchanged, and the first connecting member 251 slides relative to the first body 201.

[0077] Since the resistance is reduced when the first middle piece 241 slides relative to the first body 201, the first force provided by the first target piece 231 overcomes the smaller resistance and is transmitted to the first middle piece 241 and further applied to the first part 221, thereby providing greater stretching for the bendable portion 223 and improving the stretching effect of the crease area.

[0078] For example, because the resistance to relative sliding between the second intermediate member 242 and the second body 202 is relatively large, a second connecting member 252 may be provided in the area where the second intermediate member 242 contacts the second body 202. The second connecting member 252 must satisfy the following requirements: the resistance to relative sliding between the second connecting member 252 and the second body 202 is less than the resistance to relative sliding between the second intermediate member 242 and the second body 202. For example, the second connecting member 252 may be provided below the second intermediate member 242. When the second target member 232 applies a second force to cause the second intermediate member 242 to slide relative to the second body 202, the relative position between the second intermediate member 242 and the second connecting member 252 remains unchanged, and the second connecting member 252 slides relative to the second body 202.

[0079] Since the resistance is reduced when the second middle piece 242 slides relative to the second body 202, the second force provided by the second target piece 232 overcomes the smaller resistance and is transmitted to the second middle piece 242 and further applied to the second part 222, thereby providing greater stretching for the bendable portion 223 and improving the stretching effect of the crease area.

[0080] According to an embodiment of the present application, the first connecting member 251 and the second connecting member 252 may be Teflon films. The first intermediate member 241 is slidably connected to the first body 201 via the Teflon film, and / or the second intermediate member 242 is slidably connected to the second body 202 via the Teflon film. The relative sliding resistance between the Teflon film and the first body 201 is less than the relative sliding resistance between the first intermediate member 241 and the first body 201, and / or the relative sliding resistance between the Teflon film and the second body 202 is less than the relative sliding resistance between the second intermediate member 242 and the second body 202. The Teflon film can increase the smoothness of relative sliding, thereby providing faster and greater stretching for the bendable portion 223, and quickly flattening the crease area.

[0081] Exemplarily, the first connecting part 251 and the second connecting part 251 may also be made of other materials. The materials of the first connecting part 251 and the second connecting part 251 must meet the following requirements: the resistance of the material to relative sliding with the first body 201 is less than the resistance of the first middle piece 241 to relative sliding with the first body 201, and / or the resistance of the material to relative sliding with the second body 202 is less than the resistance of the second middle piece 242 to relative sliding with the second body 202.

[0082] According to an embodiment of the present application, the electronic device 200 also includes a first flat plate 261 and a second flat plate 262, the first surface of the first flat plate 261 is connected to the first part 221, the second surface of the first flat plate 261 is connected to the first middle piece 241, the first surface of the second flat plate 262 is connected to the second part 222, and the second surface of the second flat plate 262 is connected to the second middle piece 242, wherein the first flat plate 261 and the second flat plate 262 are carbon fiber boards.

[0083] The first flat panel 261 and the second flat panel 261 are located below the planar display area of ​​the display screen 220 and support the planar display area. For example, the first surface of the first flat panel 261 is connected to the first portion 221 and can support the first portion 221. The first surface of the second flat panel 262 is connected to the second portion 222 and can support the second portion 222.

[0084] The second surface of the first flat plate 261 is connected to the first middle piece 241, so that the first force applied to the first middle piece 241 by the first target piece 231 can be transmitted to the first flat plate 261. The first flat plate 261 is connected to the first part 221. The force on the first flat plate 261 pulls the bendable portion 223 connected to the first part 221 along the first direction, so that the fold area of ​​the bendable portion 223 remains flat, wherein the first direction is the direction from the bendable portion 223 to the first part 221.

[0085] The second surface of the second flat plate 262 is connected to the second middle piece 242, so that the second force applied to the second middle piece 242 by the second target piece 232 can be transmitted to the second flat plate 262. The second flat plate 262 is connected to the second part 222. The force on the second flat plate 262 pulls the bendable portion 223 connected to the second part 222 along the second direction, so that the fold area of ​​the bendable portion 223 remains flat, wherein the second direction is the direction from the bendable portion 223 to the second part 222.

[0086] The first flat plate 261 and the second flat plate 262 may be carbon fiber boards. Carbon fiber boards are short for carbon fiber reinforced composite boards, which are high-performance boards made by compounding carbon fibers and a resin matrix (eg, epoxy resin) through a specific process.

[0087] The first force applied by the first target member 231 does not directly act on the first part 221, but acts on the first flat plate 261. The second force applied by the second target member 232 does not directly act on the second part 222, but acts on the second flat plate 262. This can avoid damage to the display screen 220 caused by the first force or the second force being directly applied to the display screen 220, protect the integrity of the display screen 220, and extend the service life of the electronic device.

[0088] The following will refer to Figure 3 and Figure 4 The connection between the first tablet 261 , the second tablet 262 and the display screen 220 is described.

[0089] Figure 3 A schematic diagram showing the connection relationship of the display screen 220 in the electronic device according to an embodiment of the present application, and Figure 4 Schematically shows the embodiment of the present application Figure 3 The exploded diagram corresponding to the structural diagram.

[0090] Reference Figure 4 There is a corresponding relationship between the display screen 220 of the electronic device 200 and the first tablet 261 , the second tablet 262 , the first middleware 241 , the second middleware 242 and the connecting device 210 .

[0091] Reference Figure 3 and Figure 4 The first flat panel 261 and the second flat panel 262 are disposed on the lower surface of the display screen 220. The first flat panel 261 is disposed on the lower surface of the first planar display area (first portion 221), and the second flat panel 262 is disposed on the lower surface of the second planar display area (second portion 222). The connecting device 210 is disposed between the first flat panel 261 and the second flat panel 262. The first intermediate member 241 is disposed on the lower surface of the first flat panel 261 and is connected to an edge of the first flat panel 261 away from the connecting device 210. The second intermediate member 242 is disposed on the lower surface of the second flat panel 262 and is connected to an edge of the second flat panel 262 away from the connecting device 210.

[0092] According to an embodiment of the present application, the first target member 231 includes: a first support portion 2311, which is provided on the first body 201; a first guide portion 2312, which is connected to the first support portion 2311 and is provided on a side of the first support portion 2311 away from the connecting device 210, and the first guide portion 2312 is parallel to the first portion 221; a first movable portion 2314, which is provided at one end of the first guide portion 2312 away from the first support portion 2311, and the first force is applied to the first portion 221 through the first movable portion 2314; a first deformation portion 2313, which is provided on the first guide portion 2 312; and / or the second target part 232 includes: a second supporting portion 2321, which is arranged on the second body 202; a second guide portion 2322, which is connected to the second supporting portion 2321 and is arranged on the side of the second supporting portion 2321 away from the connecting device 210, and the second guide portion 2322 is parallel to the second part 202; a second movable portion 2324, which is arranged at one end of the second guide portion 2322 away from the second supporting portion 2321, and the second force is applied to the second part 222 through the second movable portion 2324; a second deformation portion 2323, which is arranged on the second guide portion 2322.

[0093] Exemplarily, the first target part 231 of the electronic device 200 may include a fixed portion and a variable portion. For example, the first supporting portion 2311 and the first guiding portion 2312 may serve as the fixed portion, and the first deformable portion 2313 and the first movable portion 2314 may serve as the variable portion. Figure 2 The first support portion 2311 is provided on the first body 201 and is used to fix one end of the first deformable portion 2313. In this case, the other end of the first deformable portion 2313 (for example, the end away from the first support portion 2311) moves under the action of the elastic restoring force. For example, the spring is in a compressed state. In order to restore the original length, the end of the spring away from the first support portion moves in a direction away from the first support portion, driving the first movable portion to move, thereby pushing the first intermediate piece.

[0094] The first guide portion 2312 is disposed on a side of the first support portion 2311 away from the connecting device 210 and is connected to the first support portion 2311. The first guide portion 2312 is a component parallel to the first portion 221. For example, the first support portion 2311 is a rod perpendicular to the first body 201, while the first guide portion 2312 is a rod parallel to the flat display area. One end of the first guide portion 2312 is connected to the first support portion 2311, and the first guide portion 2312 is perpendicular to the bending direction of the electronic device. The first guide portion 2312 may be provided with a first deformable portion 2313. The first guide portion 2312 can guide the first deformable portion 2313. The first deformable portion 2313 elastically deforms along the direction of the first guide portion 2312, and the direction in which the first deformable portion 2313 recovers its elastic deformation is also along the first guide portion 2312. The first deformable portion 2313 can be arranged along the first guide portion 2312, and the first deformable portion 2313 can be sleeved on the first guide portion 2312. For example, the first guide portion 2312 can be provided in the hollow portion in the middle of the spring. Figure 2 As shown, the first deformable portion 2313 may be a spring, and the first guide portion 2312 may be a rod in the middle of the spring. Figure 2 The first guide portion 2312 and the first deformable portion 2313 are merely examples, and the structures of the first guide portion 2312 and the first deformable portion 2313 are not limited thereto. For example, the first guide portion 2312 may be a hollow three-dimensional space, and the first deformable portion 2313 may be an elastic member in a deformed state.

[0095] The first movable portion 2314 is disposed at an end of the first guide portion 2312 away from the first support portion 2311. The first deformable portion 2313 can be disposed between the first movable portion 2314 and the first support portion 2311. A first force exerted by the first deformable portion 2313 to restore its elastic deformation is applied to the first movable portion 2314. The first movable portion 2314 contacts the first intermediate member 241, which is connected to the first portion 221. Thus, the first force is applied to the first portion 221 via the first movable portion 2314. For example, when a spring returns to its original length from a compressed state, the elastic force generated acts on the first movable portion, which transmits the elastic force to the first intermediate member. The force applied to the first intermediate member is then applied to the first portion, thereby stretching the bendable portion through the first portion.

[0096] Exemplarily, the first movable portion 2314 can be a movable component that is slidably connected to the first guide portion 2312, the boundary of the first movable portion 2314 is slidably connected to the first guide portion 2312, or the first movable portion 2314 has the first guide portion 2312 extending therethrough. For example, the first movable portion 2314 is a three-dimensional block with a central perforation, and the first movable block 2314 is movably connected to the first guide portion 2312 through the hole. The first movable portion 2314 and the first guide portion 2312 can have mutually nested structures so that the contact positions of the first movable portion 2314 and the first guide portion 2312 can match, achieving stable sliding. For example, the first movable portion 2314 includes an outwardly protruding bump, and the first guide portion 2312 may include an inwardly recessed slide rail that mates with the edge of the bump, and the bump and the inner edge of the slide rail have the same shape, so that the bump can slide stably within the slide rail without offset. For another example, the first movable portion 2314 is a three-dimensional block with a center passing through it and a circular cross section. The first guide portion 2312 may be a cylindrical rod with a cross-sectional radius smaller than the circular radius.

[0097] The first deformable portion 2313 undergoes elastic deformation, with the first target state being a deformed state. In this deformed state, a first force is applied in a first direction. Because the end of the first deformable portion 2313 proximal to the connecting device 210 is connected to the first support portion 2311, and the first support portion 2311 is disposed on the first body 201 (e.g., fixed to the first body 201), when the deformation is restored, the end of the first deformable portion 2313 distal to the connecting device 210 is in a restoring state, applying a force along the first guide portion 2312 in a direction away from the first support portion 2311, i.e., the first force, causing the end of the first deformable portion 2313 distal to the connecting device 210 to move away from the connecting device 210. The first deformable portion 2313 may be an elastically deformable component, such as a spring, a rubber component, or the like.

[0098] like Figure 2As shown, the second target member 232 of the electronic device 200 may include a fixed portion and a variable portion. For example, the second supporting portion 2321 and the second guiding portion 2322 may serve as the fixed portion, while the second deformable portion 2323 and the second movable portion 2324 may serve as the variable portion. The second supporting portion 2321 is provided on the second body 202 and is used to fix one end of the second deformable portion 2323. In this case, the other end of the second deformable portion 2323 (e.g., the end away from the second supporting portion 2321) moves under the action of an elastic restoring force. For example, when a spring is in a compressed state, the end of the spring away from the second supporting portion moves away from the second supporting portion to restore its original length, driving the second movable portion to move, thereby pushing the second intermediate member.

[0099] The second guide portion 2322 is disposed on a side of the second support portion 2321 away from the connecting device 210 and is connected to the second support portion 2321. The second guide portion 2322 is a component parallel to the second portion 222. For example, the second support portion 2321 is a rod perpendicular to the second body 202, while the second guide portion 2322 is a rod parallel to the flat display area. One end of the second guide portion 2322 is connected to the second support portion 2321, and the second guide portion 2322 is perpendicular to the bending direction of the electronic device. The second guide portion 2322 may be provided with a second deformable portion 2323, which can guide the second deformable portion 2323. The second deformable portion 2323 elastically deforms along the direction of the second guide portion 2322, and the direction in which the second deformable portion 2323 recovers its elastic deformation is also along the second guide portion 2322. The second deformable portion 2323 can be arranged along the second guide portion 2322, and the second deformable portion 2323 can be sleeved on the second guide portion 2322. For example, the second guide portion 2322 can be provided in the hollow portion in the middle of the spring. Figure 2 As shown, the second deformable portion 2323 may be a spring, and the second guide portion 2322 may be a rod in the middle of the spring. Figure 2 The second guide portion 2322 and the second deformable portion 2323 are merely examples, and the structures of the second guide portion 2322 and the second deformable portion 2323 are not limited thereto. For example, the second guide portion 2322 may be a hollow three-dimensional space, and the second deformable portion 2323 may be an elastic member in a deformed state.

[0100] The second movable portion 2324 is disposed at an end of the second guide portion 2322 away from the second support portion 2321. The second deformable portion 2323 can be disposed between the second movable portion 2324 and the second support portion 2321. A second force exerted by the second deformable portion 2323 to restore its elastic deformation is applied to the second movable portion 2324. The second movable portion 2324 contacts the second intermediate member 242, which is connected to the second portion 222. Thus, the second force is applied to the second portion 222 via the second movable portion 2324. For example, when a spring returns to its original length from a compressed state, the elastic force generated acts on the second movable portion, which transmits the elastic force to the second intermediate member. The force applied to the second intermediate member is then applied to the second portion, thereby stretching the bendable portion.

[0101] Exemplarily, the second movable portion 2324 can be a movable component that is slidably connected to the second guide portion 2322, the boundary of the second movable portion 2324 is slidably connected to the second guide member 2322, or the second movable portion 2324 has the second guide portion 2322 extending therethrough. For example, the second movable portion 2324 is a three-dimensional block with a central perforation, and the second movable block 2324 is movably connected to the second guide portion 2322 through the hole. The second movable portion 2324 and the second guide portion 2322 can be nested with each other so that the contact positions of the second movable portion 2324 and the second guide portion 2322 can match to achieve stable sliding. For example, the second movable portion 2324 includes an outwardly protruding protrusion, and the second guide portion 2322 can include an inwardly recessed slide rail that cooperates with the edge of the protrusion, and the protrusion and the inner edge of the slide rail have the same shape, so that the protrusion can slide stably within the slide rail without offset. For another example, the second movable portion 2324 is a three-dimensional block with a center passing through it and a circular cross section. The second guide portion 2322 may be a cylindrical rod with a cross-sectional radius smaller than the circular radius.

[0102] The second deformable portion 2323 undergoes elastic deformation, and the second target state is a deformed state, in which a second force in a second direction is applied. Because the end of the second deformable portion 2323 proximal to the connecting device 210 is connected to the second support portion 2321, and the second support portion 2321 is disposed on the second body 202 (e.g., fixed to the second body 202), when the deformation is restored, the end of the second deformable portion 2323 distal to the connecting device 210 is in a restoring state, applying a force along the second guide portion 2322 away from the second support portion 2321, i.e., the second force, causing the end of the second deformable portion 2323 distal to the connecting device 210 to move away from the connecting device 210. The second deformable portion 2323 may be an elastically deformable component, such as a spring, a rubber component, etc.

[0103] The first target part 231 includes a first support part 2311, a first guide part 2312, a first deformation part 2313 and a first movable part 2314, and the second target part 232 includes a second support part 2321, a second guide part 2322, a second deformation part 2323 and a second movable part 2324, so that the first target part 231 can apply a first force toward the first direction in the first target state, and the second target part 232 can apply a second force toward the second direction in the second target state.

[0104] Figure 5 A schematic diagram schematically illustrates the force application directions of the first target component 231 and the second target component 232 of the electronic device according to an embodiment of the present application.

[0105] like Figure 5 As shown, the first target member 231 is applied in the first target state along the bendable portion 223 toward the first portion 221 ( Figure 6 The second target member 232 applies a first force in the first direction A along the bendable portion 223 in the second target state. Figure 6 A second force in a second direction B).

[0106] According to an embodiment of the present application, one end of the first target member 231 or the second target member 232 is fixed, while the other end is movable and deformed in a direction parallel to the planar display area. This can provide stable stretching along a fixed direction for the display screen 220, thereby flattening the crease area. Since the first guide portion 2312 and the second guide portion 2312 are parallel to the planar display area, the first deforming portion 2313 is provided on the first guide portion 2312, and the second deforming portion 2323 is provided on the second guide portion 2322. Therefore, the maximum force can be provided with the minimum deformation, thereby reducing the manufacturing cost of the electronic device 200. Since the deforming portion is provided on the guide portion, the force exerted by the target member on the display screen 220 is always parallel to the planar display area, which can prevent forces in other directions from damaging the display screen 220, such as stretching the display screen 220 in a direction perpendicular to the display screen 220. The first deformable portion 2313 is disposed on the first guide portion 2312, and the second deformable portion 2323 is disposed on the second guide portion 2322, helping to prevent the deformable portion from deforming in other directions, which could result in poor restoration of the crease area and shorten the lifespan of the electronic device. The first movable portion 2314 and the second movable portion 2324 prevent the deformable portion from directly acting on the middle component, thereby more evenly applying force to the middle component and preventing deformation of the middle component due to the action of the deformable portion. For example, if the deformable portion is a spring and there is no movable portion, a single point at one end of the spring would contact the middle component. Under the action of multiple springs or over a long period of time, the middle component is likely to deform, thereby reducing the lifespan of the electronic device.

[0107] According to an embodiment of the present application, the first body 201 is provided with n first target parts 231, where n is an integer greater than 1; the n first target parts 231 all apply a first force toward the first direction in the first target state, wherein the n first movable parts 2314 corresponding to the n first target parts 231 are located on a first straight line perpendicular to the first direction; and / or the second body 202 is provided with m second target parts 232, where m is an integer greater than 1; the m second target parts 232 all apply a second force toward the second direction in the second target state, wherein the m second movable parts 2324 corresponding to the m second target parts 232 are located on a second straight line perpendicular to the second direction.

[0108] For example, a plurality of first target members 231 can be provided on the first body 201. Each of the plurality of first target members 231 is in a compressed state. Each first target member 231 applies a first force in a first direction. The plurality of first forces are applied to the first portion 221, thereby stretching the bendable portion 223 through the first portion 221, thereby providing a better stretching effect for the folding area. The plurality of first target members 231 can be n, where n can be any integer, such as 2, 3, 5, 8, 20, etc.

[0109] To provide a uniform stretching effect on the folding area, the positions of the plurality of first target elements 231 can be defined. For example, the positions of the various components comprising the first target element 231 can be defined. The plurality of first target elements 231 can be identical, with the first support portion 2311, first guide portion 2312, first movable portion 2314, and first deformable portion 2313 of these first target elements 231 being identical. The first support portions 2311 of the plurality of first target elements 231 are placed on the first body 201 and along a first straight line. The first straight line is perpendicular to the first direction and parallel to the bending direction of the electronic device 200. As a result, the plurality of first guide portions 2312, the plurality of first deformable portions 2313, and the plurality of first movable portions 2314 of the plurality of first target elements 231 are aligned. For example, the plurality of first guide portions 2312 are located in a first region, with the boundaries of the first guide portions 2312 at both ends of the first guide portions 2312 in the first region being parallel to the first straight line, and the plurality of first movable portions 2314 are located on another straight line parallel to the first straight line. By aligning and arranging multiple first target parts 231, multiple first forces applied by multiple first target parts 231 can all be applied to the first middle part 241, preventing the first forces applied by some first target parts 231 from being too small, causing the first movable part 2314 to fail to contact the first middle part 241, thereby wasting resources. Under the action of multiple aligned and identical first target parts 231, the contact surface between the first middle part 241 and the first target part 231 is subjected to a balanced force, and the first part 221 of the display screen 220 is also subjected to a balanced force, ultimately providing balanced stretching for the edge of the bendable portion 223, so that the crease area remains flat. For example, three first target parts 231 can be used to apply three first forces from the bendable portion 223 to the first part 221, and the three first forces are evenly applied to the first middle part 241. The first middle part 241 is connected to the flat display area (first part 221) away from the outer boundary of the bendable portion 223, so that the three forces act evenly on the outer boundary of the flat display area, stretching the crease of the bendable portion 223 through the flat display area.

[0110] Exemplarily, the multiple first movable portions 2314 of the multiple first target parts 231 can be connected so that the multiple first movable portions 2314 are in a straight line, so that the first forces applied by the multiple first target parts 231 act on the first intermediate part 241 at the same time.

[0111] Figure 6 The structure diagram schematically shows some components provided on the first body 201 and the second body 202 of the electronic device 200 according to an embodiment of the present application.

[0112] like Figure 6As shown, a plurality of first target parts 231 are provided on the first body 201 , the first movable parts 2314 of the plurality of first target parts 231 are connected together, the plurality of first movable parts 2314 are in a straight line, and the plurality of first movable parts 2314 act together on the first intermediate part 241 .

[0113] In fact, even if some components of the multiple first target parts 231 are different, it does not affect the multiple first target parts 231 applying the same first force toward the first direction in the first target state. The length of the first support part 2311, the shape of the first movable part 2314, the length of the first guide part 2312, the shape of the first deformation part 2313, etc. sometimes do not affect the first force applied by the first target part 231. For example, as long as the spring coefficients and deformation amounts of different springs are the same, the thickness and materials of the springs are different, the first forces provided by different springs can also be the same.

[0114] For example, a plurality of second target elements 232 can be provided on the second body 202. Each of the plurality of second target elements 232 is in a compressed state. Each second target element 232 applies a second force in a second direction. The plurality of second forces are applied to the second portion 222, thereby stretching the bendable portion 223 through the second portion 222, thereby providing a better stretching effect on the folding area. The plurality of second target elements 232 can be m, where m can be any integer, such as 2, 3, 5, 8, 20, etc.

[0115] To provide a uniform stretching effect on the folding area, the positions of the plurality of second target elements 232 can be defined. For example, the positions of the various components comprising the second target element 232 can be defined. The plurality of second target elements 232 can be identical, with the second support portion 2321, second guide portion 2322, second movable portion 2324, and second deformable portion 2323 of these second target elements 232 being identical. The second support portions 2321 of the plurality of second target elements 232 are placed on the second body 202 and along a second straight line perpendicular to the second direction and parallel to the bending direction of the electronic device 200. As a result, the plurality of second guide portions 2322, the plurality of second deformable portions 2323, and the plurality of second movable portions 2324 of the plurality of second target elements 232 are aligned. For example, the plurality of second guide portions 2322 are located in the second region, the boundaries of the two ends of the second guide portions 2322 in the second region are parallel to the second straight line, and the plurality of second movable portions 2324 are located on another straight line parallel to the second straight line. By aligning and arranging multiple second target parts 232, multiple second forces applied by multiple second target parts 232 can all be applied to the second intermediate part 242, preventing the second forces applied by some second target parts 232 from being too small, causing the second movable part 2324 to fail to contact the second intermediate part 242, resulting in waste of resources. Under the action of multiple aligned and identical second target parts 232, the contact surface between the second middle part 242 and the second target part 232 is subjected to a balanced force, and the second part 222 of the display screen 220 is also subjected to a balanced force, ultimately providing balanced stretching for the edge of the bendable portion 223, so that the crease area remains flat. For example, three second target parts 232 can be used to apply three second forces from the bendable portion 223 to the second part 222, and the three second forces are evenly applied to the second middle part 242. The second middle part 242 is connected to the flat display area (second part 222) away from the outer boundary of the bendable portion 223, so that the three forces act evenly on the outer boundary of the flat display area, stretching the crease of the bendable portion 223 through the flat display area.

[0116] For example, the second movable portions 2324 of the second target members 232 may be connected so that the second movable portions 2324 are in a straight line, so that the second forces applied by the second target members 232 act on the second intermediate member 242 simultaneously.

[0117] like Figure 6 As shown, a plurality of second target members 232 are provided on the second body 202 , and the second movable portions 2324 of the plurality of second target members 232 are connected together. The plurality of second movable portions 2324 are located in a straight line, and the plurality of second movable portions 2324 act together on the second intermediate member 242 .

[0118] In fact, even if some components of the multiple second target parts 232 are different, it does not affect the multiple second target parts 232 applying the same second force toward the second direction in the second target state. The length of the second support part 2321, the shape of the second movable part 2324, the length of the second guide part 2322, the shape of the second deformation part 2323, etc. sometimes do not affect the second force applied by the second target part 232. For example, as long as the spring coefficients and deformation amounts of different springs are the same, the thickness and materials of the springs are different, the second forces provided by different springs can also be the same.

[0119] For example, the values ​​of n and m can be the same, and the same number of elastic members, active drive devices, or passive drive devices can be provided on the first body 201 and the second body 202. For example, n and m can both be 5. The first target member 231 and the second target member 232 can be identical. Identical elastic members are provided on both sides of the connecting device 210. The first target member 231 and the second target member 232 are identical, and their positions and numbers are also identical. This arrangement can apply the same force to the first portion 221 and the second portion 222, causing the bendable portion 223 to be uniformly stretched. For example, the first body 201 is provided with five first target members 231, and the second body 202 is provided with five second target members 232. The first target members 231 and the second target members 232 are identical, so that the same force is applied to the first portion 201 and the second portion 202.

[0120] Figure 7 The figure schematically shows an overall exploded view of an electronic device 700 according to an embodiment of the present application.

[0121] like Figure 7 As shown, the electronic device 700 includes a panel box 701, a display screen 702, a flat panel 703, a deformation part 704, a deformation bracket 705, an intermediate piece 706, a connecting device 707, a connecting component 708 and a housing 709. The panel box 701 may be Figure 2 The panel box 280 in the display 702 can be Figure 2 The display screen 220 in the tablet 703 may include Figure 2 The first plate 261 and the second plate 262 in the deformation portion 704 may be Figure 2 The first deformable portion 2313 or the second deformable portion 2323 in the embodiment; the deformable bracket 705 may include Figure 2 The first supporting portion 2311, the first guiding portion 2312 and the first movable portion 2314, or the second supporting portion 2321, the second guiding portion 2322 and the second movable portion 2324; the middle piece 706 may be Figure 2 The first middleware 241 or the second middleware 242 in the embodiment; the connecting device 707 may be Figure 2The connecting device 210 in the embodiment; the connecting member 708 may be Figure 2 The first connecting member 251 or the second connecting member 252; the housing 9 may include Figure 2 The first body 201 and the second body 202 in the embodiment of the present invention are shown in FIG. Figure 7 The exploded view of FIG. 7 only shows some components of the electronic device 700 .

[0122] Figure 8 Schematically shows the embodiment of the present application Figure 7 The exploded view corresponds to the structural diagram of the electronic device 700.

[0123] Figure 8 The structure diagram shown can be Figure 7 The structure of the components in the exploded diagram is combined together. Here, the components in the structure diagram are not described in detail. It should be noted that the electronic device 700 may also include other components. In order to clearly show the structure of the electronic device 700, Figure 8 Other components of the electronic device 700, such as chips, batteries, etc., are not shown.

[0124] According to an embodiment of the present application, the first body 201 is provided with a first limit member 271, wherein the first intermediate member 241 is located between the first limit member 271 and the first target room 231, and the second body 202 is provided with a second limit member 272, wherein the second intermediate member 242 is located between the second limit member 272 and the second target room 232.

[0125] The first limit member 271 is used to limit the sliding of the first middle member 241 to a preset range, so as to prevent the first force applied when the first target member 231 recovers its elastic deformation from being too large, causing the sliding of the first middle member 241 to exceed the preset range, so that the first middle member 241 drives the first part 221, and the stretching of the display screen exceeds the tolerance range of the display screen 220, thereby damaging the integrity of the display screen 220, for example, causing the display screen 220 to break.

[0126] The first limiting member 271 may include a first limiting portion 2711 and a second limiting portion 2712. The first limiting portion 2711 is disposed on the first body 201. For example, the first limiting portion 2711 may be integrally formed with the first body 201 or may be a separate component from the first body 201. The second limiting portion 2712 may be fixed by the first limiting portion 2711. For example, the first end of the second limiting portion 2712 may be disposed on the first limiting portion 2711. The first limiting portion 2711 fixes the second limiting portion 2712 and also supports the first limiting portion 2711. The second end of the second limiting portion 2712 is located above the first limiting portion 2711. The orthographic projection of the second end of the second limiting portion 2712 on the first body 201 is larger than the orthographic projection of the first limiting portion 2711 on the first body 201. The length of the second end of the second limiting portion 2712 in the first direction is greater than the length of the first limiting portion 2711 in the first direction, so that the second end of the second limiting portion 2712 can limit the first middle piece 241 from separating from the first body 201 between the edge of the first part 221 and the shell boundary of the electronic device 200.

[0127] According to an embodiment of the present application, the first limiting portion 2711 of the first limiting member 271 is used to limit the sliding direction of the first middle member 241 along the first body 201, and the second limiting portion 2712 of the first limiting member 271 is mainly used to limit the movement of the first middle member 241 in the direction from the first body 201 to the first part 221.

[0128] A gap 291 exists between the first limiting member 271 and the first intermediate member 241 to provide a sliding range for the first intermediate member 241 , so that the first intermediate member 241 can slide along the first body 201 under the action of the first force.

[0129] In practice, there is also a gap between the first stopper 271 and the side housing of the electronic device 200. The side housing may be part of the first body 201 or a separate component from the first body 201. If the side housing is not part of the first body 201, the side housing is located between the first portion 221 and the first body 201, connected to the outer edge of the first body 201 away from the connecting device 210, and connected to the outer edge of the first portion 221 away from the connecting device 210 or connected through the panel box 280. The gap between the first stopper 271 and the side housing of the electronic device 200 facilitates assembly of the electronic device 200.

[0130] The second limit member 272 is used to limit the sliding of the second middle member 242 to a preset range, so as to prevent the second force applied when the second target member 232 recovers its elastic deformation from being too large, causing the sliding of the second middle member 242 to exceed the preset range, so that the second middle member 242 drives the second part 222, and the stretching of the display screen exceeds the tolerance range of the display screen 220, thereby destroying the integrity of the display screen 220, for example, causing the display screen 220 to break.

[0131] The second limiting member 272 may include a second limiting portion 2721 and a second limiting portion 2722. The second limiting portion 2721 is disposed on the second body 202. For example, the second limiting portion 2721 may be integrally formed with the second body 202 or may be a separate component from the second body 202. The second limiting portion 2722 may be fixed by the second limiting portion 2721. For example, the first end of the second limiting portion 2722 may be disposed on the second limiting portion 2721. The second limiting portion 2721 fixes the second limiting portion 2722 and also supports the second limiting portion 2721. The second end of the second limiting portion 2722 is located above the second limiting portion 2721. The orthographic projection of the second end of the second limiting portion 2722 on the second body 202 is larger than the orthographic projection of the second limiting portion 2721 on the second body 202. The length of the second end of the second limiting portion 2722 in the second direction is greater than the length of the second limiting portion 2721 in the second direction, so that the second end of the second limiting portion 2722 can limit the second middle piece 242 from separating from the second body 202 between the edge of the second part 222 and the shell boundary of the electronic device 200.

[0132] According to an embodiment of the present application, the second limiting portion 2721 of the second limiting member 272 is used to limit the sliding direction of the second middle member 242 along the second body 202, and the second limiting portion 2722 of the second limiting member 272 is mainly used to limit the movement of the second middle member 242 in the direction from the second body 202 to the second part 222.

[0133] A gap 292 exists between the second limiting member 272 and the second intermediate member 242 to provide a sliding range for the second intermediate member 242 , so that the second intermediate member 242 can slide along the second body 202 under the action of the second force.

[0134] In practice, there is also a gap between the second stopper 272 and the side housing of the electronic device 200. The side housing may be part of the second body 202 or a separate component from the second body 202. If the side housing is not part of the second body 202, the side housing is located between the second portion 222 and the second body 202, connected to the outer edge of the second body 202 away from the connecting device 210, and connected to the outer edge of the second portion 222 away from the connecting device 210 or connected through the panel box 280. The gap between the second stopper 272 and the side housing of the electronic device 200 facilitates assembly of the electronic device 200.

[0135] Through the limiting function of the first limiting member 271 and the second limiting member 272 , the force applied to the display screen 200 is limited to a specific range, thereby avoiding destructive stretching of the display screen 200 and extending the service life of the electronic device 200.

[0136] According to an embodiment of the present application, the electronic device 200 further includes: a panel box 280 disposed at an edge of the display screen 220 , wherein the lower surface of the panel box 280 is in partial contact with the upper surface of the display screen 220 .

[0137] The panel box 280 is located on the edges of the display screen 220 of the electronic device 200 . When bumped, the panel box 280 is touched first, which can protect the display screen 220 and reduce the frequency of the display screen 220 being fragile.
