[0002] Electronic devices such as mobile phones and tablet computers have become essential technological products in people's lives, studies, and entertainments. Currently, after the flexible display screen of a foldable electronic device is folded in half, it is convenient to carry. And when the flexible display screen is unfolded, it has a larger display area, making the foldable electronic device more and more popular among consumers.

[0003] In the related art, a foldable electronic device usually uses a hinge mechanism to drive the housing assembly to rotate to realize the unfolding or folding in half of the flexible display screen. And in order to avoid the hinge mechanism, a traditional housing assembly is provided with an avoidance groove at the edge of the flexible display screen. This will cause the flexible display screen in the avoidance groove area to have no protection, and it is easy to have local black screens or damage, which is not conducive to improving the reliability of the foldable electronic device. Summary of the Utility Model

[0020] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects:

[0021] When the housing device is in use, the telescopic unit is installed on the base frame assembly, so that the elastic buffer member is disposed between the two first side portions, and the buffer body covers the avoidance groove. Rotating the rotating assembly can drive the housing body to move relative to the base frame assembly with the rotating assembly, realizing the unfolding or folding of the housing body. When the housing device rotates from the folded state to the unfolded state, the driving unit can drive the telescopic unit, so that the telescopic portion can drive the buffer body to move away from the base frame assembly to form a larger first gap to form the space required for the deformation of the flexible display screen. When the housing device is in the unfolded state, the telescopic portion can drive the buffer body to move toward the base frame assembly, thereby reducing the first gap, which can effectively improve the appearance fineness of the foldable electronic device. When the housing device is in the unfolded state, at least a part of the buffer body is disposed between the two housing bodies to cover the avoidance groove and can be used to protect the flexible display screen. Thus, the protection assembly can effectively protect the flexible display screen, which is beneficial to improving the reliability of the foldable electronic device.

[0022] The technical solutions of the present disclosure will be further described below:

[0023] In one embodiment, when the housing device is in the unfolded state, at least a part of the buffer body bends away from the connecting member to form a protective space for protecting the flexible display screen.

[0025] In one embodiment, when the housing device is in the unfolded state, at least a part of the buffer body is suspended above the base frame assembly to protect the flexible display screen;

[0026] And / or, the material of the elastic protective member is TPU;

[0027] And / or, along the thickness direction of the flexible display screen, the distance L1 between the buffer body and the bending portion of the flexible display screen satisfies 0.2mm ≤ L1 < 0.6mm; when the housing device rotates from the folded state to the unfolded state, the telescopic portion can drive the buffer body to move away from the base frame assembly to increase L1.

[0029] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects:

[0030] When the foldable electronic device is in use, rotating the rotating component can drive the housing body to move relative to the base frame component along with the rotating component, and the flexible display screen covers the housing device, thereby being able to drive the flexible display screen to unfold or fold in half. During this process, a part of the first edge is fixedly connected to the first side portion, and a part of the first edge is clamped between the base frame component and the buffer body. Furthermore, the elastic protection member can cooperate with the first side portion of the housing body to effectively protect the first edge.

[0044] To make the purpose, technical solutions and advantages of the present disclosure clearer and more understandable, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present disclosure and do not limit the protection scope of the present disclosure

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present disclosure belongs. The terms used in the specification of the present disclosure herein are only for the purpose of describing specific implementation manners and are not intended to limit the present disclosure

[0046] Electronic devices such as mobile phones and tablet computers have become essential technological products in people's lives, study, and entertainment, bringing a lot of convenience and fun to people's lives. With the development of the diversification of the functions of electronic devices, there are a wide variety of electronic devices and brands, making there are many electronic devices available for consumers to choose from. Just improving the functional characteristics of electronic devices cannot meet people's requirements for electronic devices.

[0047] As the application of flexible display screens becomes more and more mature, their applications on electronic devices are becoming more and more extensive. For foldable electronic devices using flexible display screens, the flexible display screens can be folded for easy carrying. And after the flexible display screens are unfolded, they have a larger display area, and thus are increasingly favored by consumers. Among foldable electronic devices with similar display sizes and performance, the lighter the foldable electronic device is, the better the holding feel is, and thus the more attractive it is for consumers to purchase.

[0048] In related technologies, in order to avoid the hinge mechanism, traditional housing components will set avoidance grooves at the edges of flexible display screens. This will result in the flexible display screens in the avoidance groove area having no protection, being prone to local black screens or damage, which is not conducive to improving the reliability of foldable electronic devices.

[0049] Based on this, the present disclosure provides a protection component. The housing device can drive the flexible display screen to fold and can effectively protect the flexible display screen, which is conducive to improving the reliability of foldable electronic devices. Moreover, in the unfolded state of the housing device, the gap can be actively reduced, improving the appearance refinement of the foldable electronic device.

[0050] To better understand the housing device of the present disclosure, it is described through a foldable electronic device applying the housing device.

[0051] As Figures 1 to 2 shown, in an embodiment of the present disclosure, a foldable electronic device 10 is provided, including a flexible display screen 100, a housing device, and a control component 10a, and the flexible display screen 100 covers the housing device.

[0052] As Figures 1 to 3As shown, the housing device includes a hinge mechanism, a housing assembly 300 and a protective assembly 400. The hinge mechanism includes a base assembly 210 and a rotating assembly 220 rotatably disposed on the base assembly 210. The rotating assembly 220 includes two groups and is spaced apart on both sides of the base assembly 210. The housing assembly 300 includes two shell bodies 310 corresponding to the rotating assembly 220. The two shell bodies 310 are spaced apart on both sides of the base assembly 210. The shell bodies 310 are transmission-connected with the corresponding rotating assembly 220 and rotate with the rotating assembly 220 relative to the base assembly 210 so that the housing device has an unfolded state and a folded state. The shell body 310 includes a first side portion 311 for fixing the edge of the flexible display screen 100. The first side portion 311 is provided with an avoidance groove 301 for avoiding the base assembly 210.

[0053] like Figure 3 as well as Figure 4 As shown, the protective assembly 400 includes a connecting member 410, an elastic protective member 420, a telescopic unit 430 and a driving unit 440. The telescopic unit 430 includes a telescopic portion 431 that can telescopically move relative to the base assembly 210. The connecting member 410 is fixed to the telescopic portion 431. The elastic protective member 420 includes a buffer body 421. The elastic protective member 420 is connected to the connecting member 410. The driving unit 440 can drive the telescopic unit 430 so that the telescopic portion 431 can drive the buffer body 421 to move toward or away from the base assembly 210. The telescopic unit 430 is installed on the base assembly 210 so that the elastic buffer is arranged between the two first side portions 311 and the buffer body 421 covers the avoidance groove 301. When the shell device rotates from the folded state to the unfolded state, the driving unit 440 can drive the telescopic unit 430 so that the telescopic portion 431 can drive the buffer body 421 to move away from the base assembly 210. When the housing device is in the unfolded state, the telescopic portion 431 can drive the buffer body 421 to move toward the base assembly 210. The base assembly 210 has a first gap control device 10a that is in communication with the drive unit 440. In this way, the drive unit 440 is controlled by the control device 10a to adjust the first gap (such as Figure 5 The size of H1) is shown.

[0054] The flexible display screen 100 includes a first edge 110, a portion of which is fixedly connected to the first side portion 311, and a portion of the first edge 110 is sandwiched between the base assembly 210 and the buffer body 421. When the housing device is in the unfolded state, at least a portion of the buffer body 421 covers the avoidance groove 301 to protect the flexible display screen 100.

[0055] In this way, when the foldable electronic device 10 is used, rotating the rotating assembly 220 can drive the shell body 310 to move with the rotating assembly 220 relative to the base assembly 210, and the flexible display screen 100 is covered on the shell device, thereby driving the flexible display screen 100 to unfold or fold. In this process, part of the first edge 110 is fixedly connected to the first side portion 311, and part of the first edge 110 is sandwiched between the base assembly 210 and the buffer body 421. Then the elastic protective member 420 can cooperate with the first side portion 311 of the shell body 310 to effectively protect the first edge 110. The control device 10a is electrically connected to the driving unit 440, so that when the shell device rotates from the folded state to the unfolded state, the driving unit 440 can drive the telescopic unit 430, so that the telescopic portion 431 can drive the buffer body 421 to move away from the base assembly 210, so as to form a larger first gap to form the space required for the deformation of the flexible display screen 100. When the shell device is in the unfolded state, the telescopic portion 431 can drive the buffer body 421 to move toward the base assembly 210, thereby reducing the first gap, which can effectively improve the appearance refinement of the foldable electronic device 10. When the shell device is in the unfolded state, at least part of the buffer body 421 is disposed between the two shell bodies 310 to cover the avoidance groove 301, and can be used to protect the flexible display screen 100. In this way, the protective assembly 400 can effectively protect the flexible display screen 100, which is beneficial to improving the reliability of the foldable electronic device 10. Moreover, when the shell device is in the unfolded state, the gap can be reduced, and the appearance refinement of the foldable electronic device 10 can be improved.

[0056] It should be noted that when the housing device is in the unfolded state, the flexible display screen 100 and the foldable electronic device 10 are also in the unfolded state (including the flattened state). When the housing device is in the folded state, the flexible display screen 100 and the foldable electronic device 10 are also in the folded state (including the folded state).

[0057] like Figure 4 As shown, in some embodiments, part of the connector 410 is fixedly connected to the end of the base assembly 210 through the telescopic unit 430, and another part of the connector 410 avoids the edge of the flexible display screen 100 and is fixedly connected to the buffer body 421, so that when the housing device is in the unfolded state, the buffer body 421 is arranged above the flexible display screen 100. In this way, the part of the connector 410 fixedly connected to the end of the base assembly 210 through the telescopic unit 430 can reduce the occupation of the internal space of the foldable electronic device 10 by the connector 410, and will not interfere with the folding of the flexible display screen 100.

[0058] It should be noted that the implementation method of “fixed connection” between the telescopic unit 430 and the end of the base assembly 210 includes but is not limited to bonding, clamping, etc.

[0059] As Figure 4 or Figure 5 shown, in some embodiments, when the housing device is in the unfolded state, at least a part of the buffer body 421 is suspended above the base frame assembly 210 to protect the flexible display screen 100. In this way, at least a part of the buffer body 421 is suspended above the base frame assembly 210, having good buffering performance and being able to effectively reduce the probability of screen breakage at the bending area of the folding mobile phone.

[0060] Optionally, when the foldable electronic device 10 is unfolded for use, in the display area, the first side portion 311 is substantially flush with the elastic protection member 420.

[0061] As Figure 5 shown, in some embodiments, along the thickness direction of the flexible display screen 100, the distance L1 between the buffer body and the bending portion 120 of the flexible display screen 100 satisfies 0.2 mm ≤ L1 < 0.6 mm; when the housing device rotates from the folded state to the unfolded state, the telescopic portion 431 can drive the buffer body 421 to move away from the base frame assembly 210 to increase L1. In this way, after applying the technical solution of the present disclosure, when the housing device is in the unfolded state, it can make the height of the buffer body 421 protruding from the flexible display screen 100 as low as possible to improve the flatness of the display area of the foldable electronic device 10. And when the housing device rotates from the folded state to the unfolded state, in order to avoid the deformation space required for the flexible display screen 100 to bend to flatten. By controlling the driving unit 440 through the controller, the telescopic portion 431 can drive the buffer body 421 to move away from the base frame assembly 210 to form a larger first gap to form the space required for the deformation of the flexible display screen 100.

[0062] Optionally, 0.2 mm ≤ L1 ≤ 0.5 mm.

[0063] Optionally, 0.2 mm ≤ L1 ≤ 0.4 mm.

[0064] Optionally, 0.2 mm ≤ L1 ≤ 0.3 mm.

[0065] Optionally, L1 = 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.5 mm, 0.6 mm, etc.

[0066] It should be noted that there can be various specific implementation manners of the telescopic unit 430, as long as it can be applied to the foldable electronic device 10.

[0067] See back Figure 4As shown, in some embodiments, the telescopic unit 430 includes a shape memory alloy. At least a part of the shape memory alloy forms a telescopic portion 431, and the telescopic portion 431 can reset to its initial state. When the driving unit 440 is disconnected from the shape memory alloy, the telescopic portion 431 is in its initial state, so that the buffer body 421 is disposed close to the base frame assembly 210. When the driving unit 440 drives the shape memory alloy, the shape memory alloy can deform to drive the telescopic portion 431 to drive the buffer body 421 away from the base frame assembly 210. In this way, at least a part of the shape memory alloy is used to form the telescopic portion 431, which occupies a small space and can meet the requirement of thinning the foldable electronic device 10.

[0068] Optionally, in some embodiments, the shape memory alloy is a temperature-induced shape memory alloy; when the driving unit 440 drives the shape memory alloy, the driving unit 440 can supply power to the shape memory alloy to cause the shape memory alloy to deform. In this way, by the driving unit 440 supplying power to the shape memory alloy, the shape memory alloy generates heat as a resistor and deforms, and drives the buffer body 421 to move through the telescopic portion 431, so that the first gap increases to meet the space required for the deformation of the flexible display screen 100.

[0069] Optionally, in some embodiments, the shape memory alloy is a magnetic shape memory alloy; when the driving unit 440 drives the shape memory alloy, the driving unit 440 can generate a magnetic field to cause the shape memory alloy to deform. In this way, the driving unit 440 can generate a magnetic field that deforms the shape memory alloy, causing the shape memory alloy to deform, and driving the buffer body 421 to move through the telescopic portion 431, so that the first gap increases to meet the space required for the deformation of the flexible display screen 100.

[0070] It can be understood that after the driving unit 440 is powered off, the shape memory alloy can automatically reset to reduce the first gap. Further, when the user uses the foldable electronic device 10, the gap between the buffer body 421 and the flexible display screen 100 is small, and the height of the buffer body 421 protruding from the flexible display screen 100 is small, which can improve the structural compactness of the foldable electronic device 10 and the flatness of the display area, and improve the appearance fineness of the foldable electronic device 10.

[0071] As Figure 5 As shown, in some embodiments, the telescopic portion 431 is nested and fitted with the connecting member 410. In this way, the parts required for fixed connection can be reduced, the connection between the telescopic portion 431 and the connecting member 410 is made more compact, which is conducive to reducing the height of the buffer body 421 protruding from the flexible display screen 100, improving the structural compactness of the foldable electronic device 10 and the flatness of the display area, and improving the appearance fineness of the foldable electronic device 10.

[0072] As Figure 5As shown, in some embodiments, one of the telescopic part 431 and the connecting member 410 is provided with a convex body 403, and the other is provided with a first connection hole 402 that is nested and fitted with the convex body 403. In this way, the nested fit of the convex body 403 with the first connection hole 402 can increase the connection area between the two and improve the connection strength.

[0073] As Figure 2 , Figure 4 and Figure 5 shown, the thickness direction of the flexible display screen 100 is the Z-axis direction. The protruding direction of the buffer body 421 is also the Z-axis direction.

[0074] As Figure 4 shown, the telescopic direction of the telescopic part reciprocates at least in the Z-axis direction, including being parallel to the Z-axis direction or intersecting with the Z-axis but not perpendicular.

[0075] As Figure 4 or Figure 5 shown, in some embodiments, when the housing device is in the unfolded state, at least part of the buffer body 421 bends away from the connecting member 410 to form a protective space 401 for protecting the flexible display screen 100. In this way, using the buffer body 421 to form the protective space 401 can effectively reduce the probability of screen breakage at the bending area of the folding mobile phone.

[0076] In some embodiments, the connecting member 410 includes a first connecting body 411 fixedly connected to the telescopic part 431 and a second connecting body 412 connected to the first connecting body 411, and the second connecting body 412 is fixedly connected to the buffer body 421.

[0077] As Figure 5 shown, in some embodiments, one end of the second connecting body 412 is fixedly connected to the first connecting body 411, and the other end of the second connecting body 412 is nested and fixed to the buffer body 421. In this way, the number of fixed connections can be reduced, making the connection between the second connecting body 412 and the buffer body 421 more compact. Furthermore, it is beneficial to reduce the height of the buffer body 421 protruding from the flexible display screen 100, improve the structural compactness of the foldable electronic device 10, and the flatness of the display area, and enhance the appearance refinement of the foldable electronic device 10.

In this way, using the buffer body 421 to wrap the connecting convex part 404 can increase the connection area between the two and improve the connection strength.

[0079] As Figure 7As shown, in some embodiments, the connecting convex portion 404 is provided with at least one second connecting hole 405, and a part of the buffer body 421 is embedded in the second connecting hole 405. In this way, by providing the second connecting hole 405, the connecting convex portion 404 and the buffer body 421 are nested with each other, further enhancing the connection strength between the two, reducing the connection thickness in the thickness direction of the flexible display screen 100, further reducing the height of the buffer body 421 protruding from the flexible display screen 100, improving the flatness of the display area of the foldable electronic device 10, and enhancing the appearance delicacy of the foldable electronic device 10.

[0080] In some embodiments, the material of the elastic protection member is TPU.
