Description

Technical Field

[0001] The present disclosure relates to the field of electronic technology, and in particular to a housing device and a foldable electronic device. Background Art

[0002] Electronic devices such as mobile phones and tablets have become indispensable technological products in people's lives, studies and entertainment. At present, foldable electronic devices using flexible displays require a mechanical hinge mechanism to fold the flexible display to ensure that there are no failures during normal use of the flexible display and that the normal bending of the flexible display is not affected. The flexible display of a foldable electronic device can be easily carried after being folded in half, and has a larger display area after being unfolded, which makes it increasingly popular among consumers.

[0003] In the related technologies of foldable electronic devices, a hinge mechanism is usually used to drive the movement of two shells to realize the unfolding or folding of the flexible display screen. There will be built-in electronic devices between the two shells, and the electronic devices between different shells need to be connected through a transmission member, which means that the transmission member needs to pass through the hinge mechanism. When the transmission member passes through the hinge mechanism, it will deform with the movement of the hinge mechanism, which is easy to lift up the flexible display screen, which is not conducive to improving the large-screen display quality of foldable electronic devices. Summary of the invention

[0004] The present disclosure provides a housing device and a foldable electronic device. The transmission component of the housing device can effectively avoid lifting the flexible display screen, which is beneficial to improving the large-screen display quality of the foldable electronic device.

[0005] The technical solution is as follows:

[0006] According to a first aspect of an embodiment of the present disclosure, a shell device is provided, comprising a hinge mechanism, a shell assembly and a transmission assembly.

The transmission assembly comprises a first transmission body fixed to the first fixing portion, a second transmission body fixed to the second fixing portion and a third transmission body connecting the first transmission body and the second transmission body.

[0007] When the shell device is in a flattened state, the support member cooperates with the first bearing surface to form a support surface, and along the thickness direction of the base frame assembly, the support member and at least part of the shell body are spaced apart to form an accommodating space.

In the process of the shell body moving with the support member, it is rotated around the base frame assembly and drives the transmission member to stretch or bend and shrink. Specifically, the shell device is in an unfolded state, and the transmission member needs to be bent to be accommodated in the accommodating space. In this process, through the first bending section and at least two second bending sections arranged in the accommodating space, the first bending section is arranged below the supporting surface during the bending and shrinking of the transmission member, and will not hit the support member and lift up the flexible display screen or directly hit the flexible line display screen.

DETAILED DESCRIPTION

[0066] In order to make the purpose, technical solution and advantages of the present disclosure more clear, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0068] In order to better understand the hinge mechanism of the present invention, a foldable electronic device using the hinge mechanism is used for illustration.

[0069] like Figures 1 to 4 As shown, in some embodiments of the present disclosure, a foldable electronic device 10 is provided, comprising a flexible display screen 10a, an electronic device, and a housing device 10b in any of the above embodiments. The housing device 10b comprises a hinge mechanism 100, and the flexible display screen 10a is covered on the housing device 10b, and is folded or unfolded by the hinge mechanism 100. The electronic device is arranged on the shell body 200. In this way, the foldable electronic device 10 is controlled by the hinge mechanism 100, and when the hinge mechanism 100 is in the unfolded state, the flexible display screen 10a is unfolded to have a larger display area, providing the user with a large-screen viewing effect. When the hinge mechanism 100 is switched to the folded state, the flexible display screen 10a is folded in half, which can reduce the display area of ​​the foldable electronic device 10 for easy carrying.

[0070] The housing device 10b further includes a housing assembly and a transmission assembly 300. The hinge mechanism 100 includes a base assembly 110 and a support member 120. The base assembly 110 includes a bottom surface 111, a first bearing surface 112 arranged opposite to the bottom surface 111, and a first fixing portion 113 arranged between the bottom surface 111 and the first bearing surface 112. The support member 120 is movably connected to the base assembly 110. The housing assembly includes a shell body 200. The shell body 200 is movably connected to the base assembly 110 and moves with the support member 120. The shell body 200 is provided with a second fixing portion 210. The transmission assembly 300 includes a first transmission body 311 fixed to the first fixing portion 113, a second transmission body 312 fixed to the second fixing portion 210, and a third transmission body 313 connecting the first transmission body 311 and the second transmission body 312. The electronic device is electrically connected to the second transmission body 312.

[0071] When the shell device 10b is in a flattened state, the support member 120 cooperates with the first bearing surface 112 to form a support surface, and along the thickness direction of the base assembly 110, the support member 120 and at least part of the shell body 200 are spaced apart to form an accommodating space 10c.

[0072] Part of the third transmission body 313 is disposed in the accommodation space 10c, and the third transmission body 313 includes a first bending section 301 bent from the first fixing portion 113 toward the support member 120 into the accommodation space 10c and at least two second bending sections 302 connected end to end, the first bending section 301 is disposed below the support surface, one end of the first bending section 301 is connected to the first transmission body 311, and one end of the second bending section 302 disposed in the accommodation space 10c is connected to the other end of the first bending section 301. Another second bending section 302 is connected to the second transmission body 312.

[0073] In this way, when the shell device 10b is applied to the foldable electronic device 10, the first transmission body 311 is connected to the first fixing part 113, and the second transmission body 312 is connected to the second fixing part 210, so as to facilitate the electrical connection of the electronic devices in different shell bodies 200 through the transmission assembly 300. When the shell body 200 moves with the support member 120, it rotates around the base assembly 110 and drives the transmission member 310 to stretch or bend and shrink. Specifically, when the shell device 10b is in the unfolded state, the transmission member 310 needs to be bent to be accommodated in the accommodating space 10c. In this process, through the first bending section 301 and at least two second bending sections 302 arranged in the accommodating space 10c, during the bending and shrinking of the transmission member 310, the first bending section 301 is arranged below the support surface, and will not hit the support member 120 and lift up the flexible display screen 10a or directly hit the flexible line display screen. In this way, the transmission component 300 of the housing device 10b can effectively avoid lifting the flexible display screen 10a, which is beneficial to improving the large-screen display quality of the foldable electronic device 10.

[0074] In some embodiments, when the housing device 10b is in a flattened state, the first bent section 301 is spaced apart from or in non-pressing contact with the support member 120, and is disposed between the support surface and the shell body 200. In this way, the first bent section 301 will not push against the support member 120, and thus will not cause the support member 120 to be lifted and the flexible display screen 10a to be lifted, so that the foldable electronic device 10 has a flat display surface when the housing device 10b is in a flattened state, which is conducive to improving the display quality.

[0075] In some embodiments, when the housing device 10b is in a flattened state, the second bending section 302 is spaced apart from the support member 120 or in non-pressing contact with the support member 120, and is disposed between the support member 120 and the housing body 200. In this way, the second bending section 302 will not push against the support member 120, and thus will not cause the support member 120 to be lifted and the flexible display screen 10a to be lifted, so that the foldable electronic device 10 has a flat display surface when the housing device 10b is in a flattened state, which is conducive to improving the display quality.

[0076] In some embodiments, when the housing device 10b is in a flattened state, the second bent section 302 is spaced apart from or in non-pressing contact with the housing body 200, and is disposed between the support member 120 and the housing body 200. In this way, the second bent section 302 will not hit the housing body 200, and the two will not interfere with each other and cause unnecessary wear, which is beneficial to improving the service life of the transmission component 300 and the durability of the foldable electronic device 10.

[0077] Based on any of the above embodiments, Figure 4 As shown, in some embodiments, when the housing device 10b is in a flattened state, there is a gap 114 between the base assembly 110 and the support member 120, and the first bent section 301 enters the accommodation space 10c through the gap 114. In this way, the gap 114 facilitates the transmission assembly 300 to come out of the base assembly 110 and enter the accommodation space 10c, and also facilitates avoiding the first bent section 301.

[0078] Optionally, in some embodiments, part of the gap 114 penetrates the support surface to form an escape space 101 for evading the third transmission body 313. In this way, the escape space 101 is used to evade the third transmission body 313, so that when the third transmission body 313 moves with the hinge mechanism 100, the first bending section 301 is bent or stretched, and the first bending section 301 is bent or stretched. The process will not interfere with the base frame assembly 110 or the support member 120, etc., which is conducive to improving the movement smoothness of the foldable electronic device 10. In addition, the first bending section 301 will not be easily worn, which is conducive to improving the service life of the transmission assembly 300 and the durability of the foldable electronic device 10.

[0079] like Figure 4As shown, in some embodiments, the base assembly 110 includes a first guide portion 115. When the housing device 10b is in a flattened state, the first guide portion 115 and the support member 120 are spaced apart to form a gap 114. In the process of switching the housing device 10b to the flattened state, the first guide portion 115 can limit the third transmission body 313 so that the third transmission body 313 is bent to form the first bending section 301. In this way, the fault tolerance of the housing device 10b can be improved. Even if the error of the relevant parts is large or the manufacturing accuracy is slightly poor, the guiding and limiting effect of the first guide portion 115 can be used to bend the stretched third transmission body 313 along a set trajectory to form the first bending section 301, which is conducive to reducing the assembly difficulty and manufacturing difficulty of the foldable electronic device 10.

[0080] In addition, after the transmission component 300 is repeatedly bent or stretched, even if the performance of the transmission component 300 is reduced, the first guide portion 115 can bend the third transmission body 313 toward the support member 120 during the process of the shell device 10b switching to the flattened state, so that the third transmission body 313 can be smoothly bent to form the first bending section 301, so that the shell component has good display quality when it is in the flattened state.

[0081] It should be noted that the specific shape of the first guide portion 115 can be various, including a guide arc surface or a guide inclined surface.

[0082] Optionally, in some embodiments, the first guide portion 115 includes a first arcuate guide surface 102, and when the housing device 10b is switched to the flattened state, the first arcuate guide surface 102 slides with the third transmission body 313. In this way, the arcuate guiding effect of the first arcuate guide surface 102 is fully utilized to slide with the third transmission body 313, thereby improving the smoothness of the folding movement of the foldable electronic device 10. Moreover, the setting of the first arcuate guide surface 102 does not produce a sharp angle to avoid scratching the isolation column and / or other devices.

[0083] In some embodiments, when the housing device 10b is in a flattened state, the first guide portion 115 is spaced apart from or in non-pressing contact with the first bending section 301. In this way, the first guide portion 115 and the first bending section 301 are not prone to wear.

[0084] like Figure 4As shown, in some embodiments, the shell body 200 is provided with a second guide portion, and along the direction from the first fixing portion 113 to the second fixing portion 210, the second guide portion is arranged between the first guide portion 115 and the second fixing portion 210. In the process of the shell device 10b switching to the flattened state, the second guide portion can limit the third transmission body 313, and cooperate with the first guide portion 115 to bend the third transmission body 313 to form at least two second bending sections 302. In this way, through the cooperation between the first guide portion 115 and the second guide portion, it is convenient to fully utilize the width direction of the foldable electronic device 10 to store at least two second bending sections 302, so that the bending amplitude of the second bending section 302 is small and it is not easy to interfere with other devices.

[0085] Similarly, the provision of the second guide portion can improve the fault tolerance of the shell device 10b. Even if the errors of related parts are large, or the manufacturing accuracy is slightly poor, the guiding and limiting effects of the second guide portion and the first guide portion 115 can be utilized to bend the stretched third transmission body 313 along a set trajectory to form the second bending section 302, which is beneficial to reducing the assembly difficulty and manufacturing difficulty of the foldable electronic device 10.

[0086] In addition, after the transmission component 300 is repeatedly bent or stretched, even if the performance of the transmission component 300 is reduced, the second guide portion can limit the third transmission body 313 during the process of the shell device 10b switching to the flattened state, so that the third transmission body 313 can be smoothly bent to form the second bending section 302, so that the shell component has good display quality when it is in the flattened state.

[0087] like Figure 4 As shown, in some embodiments, the second bending section 302 includes two, one of which is disposed between the first guide portion 115 and the second guide portion, and the second bending section 302 is connected to the other end of the first bending section 301, and its bending direction is opposite to the bending direction of the first bending section 301; the other second bending section 302 is disposed between the second guide portion and the second fixing portion 210, and is connected to the second transmission body 312. In this way, the bending direction of the third transmission body 313 can be better controlled, and the manufacturing difficulty of the transmission component 300 can be reduced.

[0088] It should be noted that the specific shape of the second guide portion can be various, including a guide arc surface or a guide inclined surface.

[0089] like Figure 4As shown, in some embodiments, the second guide portion includes a second arc-shaped guide surface, and when the housing device 10b is switched to the flattened state, the second arc-shaped guide surface slides with the third transmission body 313. In this way, the arc-shaped guiding effect of the second arc-shaped guide surface is fully utilized to slide with the third transmission body 313, reduce or avoid the occurrence of the pressing phenomenon, avoid wear, and improve the smoothness of the folding movement of the foldable electronic device 10. Moreover, the setting of the second arc-shaped guide surface will not produce a sharp angle to avoid scratching the isolation column and / or other devices.

[0090] In some embodiments, when the housing device 10b is in a flattened state, the second guide portion is spaced apart from or in non-pressing contact with the second bending section 302. In this way, the second guide portion and the second bending section 302 are not prone to wear.

[0091] like Figure 4 As shown, in any of the above-mentioned embodiments of the second guide portion, in some embodiments, the support member 120 includes a third guide portion 121. Relative to the first fixing portion 113, the third guide portion 121 is arranged close to the second fixing portion 210. When the housing device 10b switches to the flattened state, the third guide portion 121 can guide the third transmission body 313 and limit the bending direction of the third transmission body 313 together with the second guide portion, so that the third transmission body 313 is bent to form a second bending section 302 connected to the second transmission body 312. In this way, through the cooperation between the third guide portion 121 and the second guide portion, the fault tolerance of the housing device 10b can be improved. Even if the error of the relevant parts is large or the manufacturing accuracy is slightly poor, the guiding and limiting effect of the second guide portion and the third guide portion 121 can be used to bend the stretched third transmission body 313 along the set trajectory to form the second bending section 302, which is conducive to reducing the assembly difficulty and manufacturing difficulty of the foldable electronic device 10.

[0092] In addition, after the transmission component 300 is repeatedly bent or stretched, even if the performance of the transmission component 300 is reduced, the third guide portion 121 can limit the third transmission body 313 during the process of the shell device 10b switching to the flattened state, so that the third transmission body 313 can be smoothly bent to form the second bending section 302, so that the shell component has good display quality when it is in the flattened state.

[0093] It should be noted that the third guide portion 121 may have various specific shapes, including a guide arc surface or a guide inclined surface.

[0094] like Figure 4As shown, in some embodiments, the third guide portion 121 includes a third arc-shaped guide surface, and when the housing device 10b is switched to the flattened state, the third arc-shaped guide surface slides with the third transmission body 313. In this way, the arc-shaped guiding function of the third arc-shaped guide surface is fully utilized to slide with the third transmission body 313, reduce or avoid the occurrence of the pressing phenomenon, avoid wear, and improve the smoothness of the folding movement of the foldable electronic device 10. Moreover, the setting of the third arc-shaped guide surface will not produce a sharp angle to avoid scratching the isolation column and / or other devices.

[0095] In some embodiments, when the housing device 10b is in a flattened state, the third guide portion 121 is spaced apart from or in non-pressing contact with the second bending section 302. In this way, the third guide portion 121 and the second bending section 302 are not prone to wear.

[0096] like Figure 4 As shown, based on any of the above-mentioned embodiments of the first guide portion 115, in some embodiments, the support member 120 includes a fourth guide portion 122. When the housing device 10b is in the flattened state, the fourth guide portion 122 is spaced apart from the first guide portion 115 to form a gap 114. When the housing device 10b is switched to the flattened state, the fourth guide portion 122 can guide the third transmission body 313 and limit the bending direction of the third transmission body 313 together with the first guide portion 115, so that the third transmission body 313 is bent to form the first bending section 301. In this way, the fault tolerance of the housing device 10b can be improved. Even if the error of the relevant parts is large or the manufacturing accuracy is slightly poor, the guiding and limiting effects of the first guide portion 115 and the fourth guide portion 122 can be used to bend the stretched third transmission body 313 along the set trajectory to form the first bending section 301, which is conducive to reducing the assembly difficulty and manufacturing difficulty of the foldable electronic device 10.

[0097] In addition, after the transmission component 300 is repeatedly bent or stretched, even if the performance of the transmission component 300 is reduced, the fourth guide portion 122 can bend the third transmission body 313 in the opposite direction of the support member 120 during the process of the shell device 10b switching to the flattened state, so that the third transmission body 313 can be smoothly bent to form the first bending section 301, so that the shell component has good display quality when it is in the flattened state.

[0098] It should be noted that the fourth guide portion 122 may have various specific shapes, including a guide arc surface or a guide inclined surface.

[0099] like Figure 4As shown, in some embodiments, the fourth guide portion 122 includes a fourth arc-shaped guide surface, and when the housing device 10b is switched to the flattened state, the fourth arc-shaped guide surface slides with the third transmission body 313. In this way, the arc-shaped guiding effect of the fourth arc-shaped guide surface is fully utilized to slide with the third transmission body 313, thereby improving the smoothness of the folding movement of the foldable electronic device 10. Moreover, the setting of the fourth arc-shaped guide surface does not produce a sharp angle to avoid scratching the isolation column and / or other devices.

[0100] In some embodiments, when the housing device 10b is in a flattened state, the fourth guide portion 122 is spaced apart from or in non-pressing contact with the first bending section 301. In this way, the fourth guide portion 122 and the second bending section 302 are not prone to wear.

[0101] It should be noted that the first guide portion 115, the second guide portion, the third guide portion 121 or the fourth guide portion 122 guides the movement process of the third transmission body 313, which is beneficial to improving the service life of the transmission component 300 and will not easily cause breakage or abnormal noise.

[0102] In some embodiments, the length direction of the second guide portion and / or the fourth guide portion 122 may extend along the width direction of the third transmission body 313 and be in the shape of a convex rib, which is beneficial to improving the compressive strength of the support member 120 and enhancing its pressure bearing performance.

[0103] In some embodiments, along the thickness direction of the base assembly 110, the second fixing portion 210 is closer to the bottom surface 111 than the first fixing portion 113. In this way, the thickness space of the base assembly 110 is fully utilized, so that the first bending section 301 is bent toward the accommodation space 10c, so that the first bending section 301 has a larger bending space, and ensures that the first bending section 301 is arranged below the supporting surface, and will not push up the supporting member 120 and lift up the flexible display screen 10a or directly push up the flexible line display screen.

[0104] like Figure 4 As shown, in some embodiments, the second bending section 302 includes two. When the housing device 10b is in a flattened state, relative to the bottom surface 111, the first bending section 301 is in a crest shape, the second bending section 302 connected to the first bending section 301 is in a trough shape, and the other second bending section 302 is in a crest shape. In this way, the third transmission body 313 bends smoothly and fully utilizes the width space of the foldable electronic device 10 to bend or stretched.

[0105] like Figure 4 as well as Figure 5As shown, in some embodiments, when the housing device 10b switches from the flattened state to the folded state, the first bending section 301 and the second bending section 302 connected to the first bending section 301 are stretched in the opposite direction relative to the bottom surface 111. As a result, the third transmission body 313 can rotate around the base assembly 110 with the housing body 200 and move away from the base assembly 110, so as to better avoid the flexible display screen 10a, which is conducive to the inward folding of the flexible display screen 10a.

[0106] It should be noted that there may be many specific implementation methods of the first fixing portion 113 , including but not limited to screw fixing, adhesive fixing, clamping fixing, etc.

[0107] like Figure 4 As shown, in some embodiments, the first fixing portion 113 includes at least two first clamping members 105 spaced apart to form a first clamping groove 106, and the first transmission body 311 is clamped in the first clamping groove 106. In this way, the first transmission body 311 is clamped in the first clamping groove 106, and the first transmission body 311 is fixed by friction, which can reduce stress concentration and improve the service life of the transmission component 300.

[0108] Optionally, in some embodiments, the first clamping member 105 is provided with an elastic layer to better squeeze and fix the first transmission body 311 without damaging the first transmission body 311 .

[0109] It should be noted that there may be many specific implementation methods of the second fixing portion 210 , including but not limited to screw fixing, adhesive fixing, clamping fixing, etc.

[0110] like Figure 4 As shown, in some embodiments, the second fixing portion 210 includes at least two second clamping members 211 spaced apart to form a second clamping groove 212, and the second transmission body 312 is clamped in the second clamping groove 212. In this way, the second transmission body 312 is clamped in the second clamping groove 212, and the second transmission body 312 is fixed by friction, which can reduce stress concentration and improve the service life of the transmission component 300.

[0111] Optionally, in some embodiments, the second clamping member 211 is provided with an elastic layer to better squeeze and fix the second transmission body 312 without damaging the second transmission body 312 .

[0112] In some embodiments, relative to the support surface, at least one second clamping member 211 is disposed below the second transmission body 312, and a portion of the second clamping member 211 abuts against the second bending section 302. Thus, by abutting against the second bending section 302, the third transmission body 313 is guided in the opposite direction, so that the second bending section 302 does not continue to bend downward, thereby avoiding being squeezed with the edge of the second clamping member 211 and thus detrimental to improving the durability of the transmission assembly 300.

[0113] On the basis of any of the above embodiments, in some embodiments, the third transmission body 313 is flexible, and when the third transmission body 313 is in a natural state, the third transmission body 313 has a first bending section 301 and at least two second bending sections 302. In this way, the third transmission body 313 can be bent in advance so that when the third transmission body 313 is in a natural state, the third transmission body 313 has a first bending section 301 and at least two second bending sections 302. That is, when the shell device 10b is in a flattened state, the third transmission body 313 can be naturally reset to form a first bending section 301 and at least two second bending sections 302 to avoid related parts to improve durability. In the process of switching the shell assembly, the third transmission body 313 is flexible so that the first bending section 301 and the second bending section 302 can be stretched without hindering the movement of the hinge mechanism 100 and the shell body 200.

[0114] like Figure 4 As shown, in some embodiments, the transmission component 300 includes at least three transmission members 310 arranged in a stacked manner. Along the thickness direction of the base frame component 110, the first bending sections 301 of at least three transmission members 310 are staggered and stacked along the direction from the first fixing portion 113 to the second fixing portion 210, and the second bending sections 302 of at least three transmission members 310 are staggered and stacked along the direction from the first fixing portion 113 to the second fixing portion 210. In this way, during the movement of the shell device 10b, at least three transmission members 310 will be driven to move simultaneously. The lower first bending section 301 can support the upper first bending section 301, and the lower second bending section 302 can support the upper second bending section 302, so that the structure of the transmission component 300 is more compact and can reduce abnormal noise.

[0115] Furthermore, if Figure 6As shown, in some embodiments, when the housing device 10b switches to the flattened state, between the first bending segments 301 of at least three transmission members 310, the first bending segment 301 located at the bottom can support the first bending segment 301 located at the top. In this way, during the movement of the housing device 10b, at least three transmission members 310 will be driven to move simultaneously, so that the first bending segment 301 at the bottom can support the first bending segment 301 at the top, so that the abnormal sound of the upper layer hitting the lower layer without any force will not occur.

[0116] like Figure 7 As shown, in some embodiments, when the housing device 10b switches to the flattened state, the second bending segment 302 located at the bottom can support the second bending segment 302 located at the top between the second bending segments 302 of at least three transmission members 310. In this way, during the movement of the housing device 10b, at least three transmission members 310 will be driven to move simultaneously, so that the second bending segment 302 at the bottom can support the second bending segment 302 at the top, so that the abnormal sound of the upper layer hitting the lower layer without any force will not occur.

[0117] Based on any of the above embodiments, Figure 4 As shown, in some embodiments, the third transmission body 313 is bent by hot pressing so that when the third transmission body 313 is in a natural state, the third transmission body 313 has a first bending section 301 and at least two second bending sections 302. In this way, the third transmission body 313 is bent by hot pressing and bending technology so that when the third transmission body 313 is in a natural state, the third transmission body 313 has a first bending section 301 and at least two second bending sections 302. That is, when the shell device 10b is in a flattened state, the third transmission body 313 can be naturally reset to form a first bending section 301 and at least two second bending sections 302 to avoid related parts to improve durability. In the process of switching the shell assembly, the third transmission body 313 has flexibility so that the first bending section 301 and the second bending section 302 can be stretched without easily hindering the movement of the hinge mechanism 100 and the shell body 200.

[0118] like Figure 4As shown, in some embodiments, the base assembly 110 includes a support plate 116, and the first bearing surface 112 is disposed on the support plate 116; when the shell device 10b is in a flattened state, there is an avoidance space 101 between the support plate 116 and the support member 120 for avoiding the first bending section 301. In this way, the avoidance space 101 is used to avoid the third transmission body 313, so that when the third transmission body 313 moves with the hinge mechanism 100, the first bending section 301 is bent or stretched, and the first bending section 301 is bent or stretched. During the process, there will be no interference with the base assembly 110 or the support member 120, etc., which is beneficial to improve the movement smoothness of the foldable electronic device 10. In addition, the first bending section 301 will not be easily worn, which is beneficial to increase the service life of the transmission assembly 300 and improve the durability of the foldable electronic device 10.

[0119] like Figure 4 As shown, in some embodiments, the support members 120 include two and are symmetrically arranged on both sides of the base assembly 110; the shell body 200 includes two and is symmetrically arranged on both sides of the base assembly 110, and moves synchronously with the two support members 120 toward or away from each other. The second transmission body 312 and the third transmission body 313 are both two and are symmetrically arranged at both ends of the first transmission body 311. When the shell device 10b is in a flattened state, the two support members 120 cooperate with the first bearing surface 112 to form a support surface. Then, when the two shell bodies 200 are opened, the two support members 120 cooperate with the first bearing surface 112 to form a support surface to support the flexible display screen 10a, which can realize a large-screen display. When the two shell bodies 200 are folded and folded through the hinge mechanism 100, part of the flexible display screen 10a is bent inward, which can reduce the display area of ​​the foldable electronic device 10 for easy carrying.

[0120] Furthermore, along the thickness direction of the base assembly 110, the spacing between the second fixing portions 210 and the first fixing portions 113 of the two shell bodies 200 is equal. In this way, the shell bodies 200 and the support members 120 on both sides of the base assembly 110 have the same structure and are symmetrically arranged along the symmetry axis of the base assembly 110, so that the bending rules of the third transmission bodies 313 on both sides of the base assembly 110 are the same, thereby effectively avoiding unnecessary wear caused by motion interference between the transmission assembly 300 and the shell body 200, the support member 120, the base assembly 110 or the electronic device, thereby improving the service life of the foldable electronic device 10.

[0121] In some embodiments, the first transmission body 311 is integrally formed with the two second transmission bodies 312 and the two third transmission bodies 313. For example, the transmission member 310 is heat-pressed and bent into a desired shape using the aforementioned heat-pressing and bending technology, so that the two third transmission bodies 313 can be synchronously reset to a natural state.

[0122] In some embodiments, the transmission element 310 includes a flexible circuit board and is bent by heat pressing so that when the third transmission body 313 is in a natural state, the third transmission body 313 has a first bending section 301 and at least two second bending sections 302 .

[0123] like Figure 4 As shown, in some embodiments, the shell body 200 includes a first middle frame 220 and a second middle frame 230 fixedly connected to the first middle frame 220, the first middle frame 220 is provided with a second fixing portion 210, and when the shell device 10b is in a flattened state, part of the second middle frame is attached to the bottom surface 111. In this way, by combining the first middle frame 220 and the second middle frame 230 into the shell body 200, the manufacturing difficulty of the shell body 200 can be reduced. When the shell device 10b is in a flattened state, part of the second middle frame is attached to the bottom surface 111, so that the structure of the foldable electronic device 10 is more compact, which is conducive to realizing the thinness of the foldable electronic device 10.

[0124] like Figure 8 As shown, in any of the above embodiments, the hinge mechanism 100 also includes a connecting rod assembly 140 and a moving member 130 fixedly connected to the shell body 200, the support member 120 is rotatably connected to the moving member 130, and the moving member 130 is movably connected to the base frame through the connecting rod assembly 140.

[0125] Alternatively, if Figure 8 As shown, in some embodiments, the connecting rod assembly 140 includes a synchronization rod 141 and a first connecting rod 142, one end of the synchronization rod 141 is rotatably connected to the base assembly 110, the other end of the synchronization rod 141 is slidably connected to the moving member 130, and the two ends of the first connecting rod 142 are respectively rotatably connected to the base assembly 110 and the moving member 130. In this way, it is convenient to form a four-bar linkage, so that the moving member 130 and the support member 120 rotate around the base assembly 110, and the support member 120 rotates relative to the moving member 130, so that when the housing device 10b is in the folded state, an avoidance recess for avoiding the flexible display screen 10a is formed, so that the flexible display screen 10a can be folded inwardly.

[0126] Alternatively, if Fig. 9 as well as Fig.10As shown, in other embodiments, the connecting rod assembly 140 includes a transmission member 143, a first rotating member 144, a second rotating member 145 and a third rotating member 146. One end of the first rotating member 144 is rotatably connected to the base assembly 110, and the second connecting rod assembly 140 is rotatably connected to the base assembly 110. The other end of the first rotating member 144 is rotatably connected to one end of the second rotating member 145 and the other end of the transmission member 143, and the other end of the second rotating member 145 is rotatably connected to the moving member 130. The third rotating member 146 is rotatably connected to the base assembly 110 and the transmission member 143, and the third rotating member 146 is slidably connected to the moving member 130. In this way, when the foldable electronic device 10 switches from the folded state to the opened state, the hinge mechanism 100 also switches from the folded state to the unfolded state, and the connecting rod assemblies 140 on both sides of the base assembly 110 rotate around the base assembly 110, so that when the first connecting rod 142 assembly 140 and the second connecting rod assembly 140 rotate synchronously along the base assembly 110, the first rotating member 144 and the transmission member 143 can be driven to rotate when the moving member 130 is driven by the third rotating member 146, and the second rotating member 145 is driven to rotate in a set direction, so as to drive the moving member 130 to slide along the length direction of the second guide portion and be arranged close to the base assembly 110. At this time, the supporting member 120 is opened to the supporting state during the movement of the moving member 130, until the supporting member 120 cooperates with the third bearing surface to form a supporting structure, so as to use the supporting structure to support the flexible display screen 10a. When the foldable electronic device 10 is switched from the open state to the folded state, the hinge mechanism 100 is also switched from the unfolded state to the folded state, so that when the first connecting rod 142 assembly 140 and the third rotating member 146 rotate along the base assembly 110, the first rotating member 144 and the transmission member 143 can be driven synchronously to rotate the moving member 130 through the third rotating member 146, and the second rotating member 145 is driven to rotate in a set direction, so as to drive the moving member 130 to slide along the length direction of the second guide portion and be set away from the base assembly 110. At this time, in the process of the support member 120 moving with the moving member 130, the support member 120 is set at an angle relative to the third bearing surface to form an avoidance recess, until the foldable electronic device 10 is in the folded state, so that part of the flexible display screen 10a can be bent in the avoidance recess, which can reduce the bending stress on the flexible display screen 10a and improve the service life of the flexible display screen 10a.

[0127] It should be noted that foldable electronic devices include handheld display devices, vehicle-mounted display devices, monitoring display devices, cellular phones, smart phones, tablet computers, televisions, monitors, laptop computers, camcorders, video recorders, cameras, smart watches, smart wristbands, vehicle-mounted computers and other electronic devices with imaging functions.
