Description

Technical Field

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

[0002] Mobile phones, tablets, and other electronic devices have become indispensable technological products in people's lives, studies, and entertainment. Currently, foldable electronic devices using flexible displays require mechanical hinge mechanisms to fold the flexible displays, ensuring they don't malfunction during normal use and allowing for proper bending. The flexible displays in foldable electronic devices are convenient to carry when folded, and offer a larger display area when unfolded, making them increasingly popular with consumers.

[0003] In foldable electronic device technologies, a hinge mechanism is typically used to move two housings, enabling the flexible display screen to unfold or fold. Electronic components are embedded between the two housings, and these components need to be connected via a transmission device, which requires the transmission device to pass through the hinge mechanism. However, as the transmission device passes through the hinge mechanism, it deforms with the hinge's movement, potentially lifting the flexible display screen and negatively impacting the large-screen display quality of the foldable electronic device. Summary of the Invention

[0004] This disclosure provides a housing device and a foldable electronic device. The transmission component of the housing device can effectively prevent the flexible display screen from being pushed up, 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 the present disclosure, a housing device is provided, including a hinge mechanism, a housing assembly, and a transmission assembly. The hinge mechanism includes a base frame assembly and a support member. The base frame assembly includes a bottom surface, a first bearing surface opposite to the bottom surface, and a first fixing portion disposed between the bottom surface and the first bearing surface. The support member is movably connected to the base frame assembly. The housing assembly includes a housing body, which is movably connected to the base frame assembly and moves with the support member. The housing body has a second fixing portion. The transmission assembly includes 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 housing 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 the housing body are spaced apart to form an accommodating space.

[0008] A portion of the third transmission body passes through the receiving space, and the third transmission body includes a first bent segment that bends into the receiving space from the first fixing part toward the support member, and at least two second bent segments connected end to end. The first bent segment is located below the support surface, and one end of the first bent segment is connected to the first transmission body. One end of the second bent segment located in the receiving space is connected to the other end of the first bent segment. The other second bent segment is connected to the second transmission body.

[0009] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0010] When this housing device is applied to foldable electronic devices, the first transmission body is connected to the first fixing part, and the second transmission body is connected to the second fixing part, facilitating the electrical connection of electronic devices within different housing bodies via the transmission assembly. As the housing body moves with the support member, it rotates around the base frame assembly, causing the transmission member to stretch or bend and retract. Specifically, when the housing device is in the unfolded state, the transmission member needs to be bent to be housed in the receiving space. During this process, through the first bending section and at least two second bending sections located within the receiving space, the first bending section is positioned below the support surface during the bending and retraction of the transmission member, preventing it from hitting the support member and thus lifting the flexible display screen or directly hitting the flexible linear display screen. In this way, the transmission assembly of the housing device can effectively prevent lifting the flexible display screen, which is beneficial for improving the large-screen display quality of foldable electronic devices.

[0011] The technical solution of this disclosure will be further explained below:

[0027] In one embodiment, the fourth guide portion includes a fourth arcuate guide surface, which slides in conjunction with the third transmission body during the process of the housing device switching to a flattened state.

[0028] And / or, when the housing device is in a flattened state, the fourth guide portion is spaced apart from or in non-pressurized contact with the first bent section.

[0066] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0068] To better understand the hinge mechanism of this disclosure, it is illustrated by a foldable electronic device in which the hinge mechanism is applied.

[0069] like Figures 1 to 4 As shown, in some embodiments of this disclosure, a foldable electronic device 10 is provided, including a flexible display screen 10a, electronic components, and a housing device 10b as described in any of the above embodiments. The housing device 10b includes a hinge mechanism 100, and the flexible display screen 10a covers the housing device 10b and is folded or unfolded via the hinge mechanism 100. The electronic components are disposed on the housing body 200. Thus, the foldable electronic device 10 is controlled by the hinge mechanism 100. When the hinge mechanism 100 is in the unfolded state, the flexible display screen 10a unfolds to provide a larger display area and a large-screen viewing effect for the user. When the hinge mechanism 100 is switched to the folded state, the flexible display screen 10a folds in half, which reduces the display area of ​​the foldable electronic device 10 for easy carrying.

[0070] The housing device 10b also includes a housing assembly and a transmission assembly 300. The hinge mechanism 100 includes a base frame assembly 110 and a support member 120. The base frame assembly 110 includes a bottom surface 111, a first bearing surface 112 opposite to the bottom surface 111, and a first fixing part 113 disposed between the bottom surface 111 and the first bearing surface 112. The support member 120 is movably connected to the base frame assembly 110. The housing assembly includes a housing body 200, which is movably connected to the base frame assembly 110 and moves with the support member 120. The housing body 200 has a second fixing part 210. The transmission assembly 300 includes a first transmission body 311 fixed to the first fixing part 113, a second transmission body 312 fixed to the second fixing part 210, and a third transmission body 313 connecting the first transmission body 311 and the second transmission body 312. Electronic components are electrically connected to the second transmission body 312.

[0071] When the housing 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 frame assembly 110, the support member 120 and at least part of the housing body 200 are spaced apart to form an accommodating space 10c.

[0072] A portion of the third transmission body 313 passes through the receiving space 10c, and the third transmission body 313 includes a first bent segment 301 that bends from the first fixing part 113 toward the support member 120 into the receiving space 10c, and at least two second bent segments 302 connected end to end. The first bent segment 301 is located below the support surface, and one end of the first bent segment 301 is connected to the first transmission body 311. One end of the second bent segment 302 located in the receiving space 10c is connected to the other end of the first bent segment 301. The other second bent segment 302 is connected to the second transmission body 312.

[0073] Thus, when the housing 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, facilitating the electrical connection of electronic devices within different housing bodies 200 via the transmission assembly 300. As the housing body 200 moves with the support member 120, it rotates around the base frame assembly 110, causing the transmission member 310 to stretch or bend and retract. Specifically, when the housing device 10b is in the unfolded state, the transmission member 310 needs to be bent to be housed in the receiving space 10c. During this process, through the first bending segment 301 and at least two second bending segments 302 disposed within the receiving space 10c, the first bending segment 301 is positioned below the support surface during the bending and retraction of the transmission member 310, preventing it from hitting the support member 120 and lifting the flexible display screen 10a or directly hitting the flexible linear 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 bending segment 301 is spaced apart from or in non-pressing contact with the support member 120, and is disposed between the support surface and the housing body 200. Thus, the first bending segment 301 will not abut against the support member 120, thereby preventing the support member 120 from being lifted and the flexible display screen 10a from being lifted. This ensures that the foldable electronic device 10 has a flat display surface when the housing device 10b is in a flattened state, which is beneficial for improving display quality.

[0075] In some embodiments, when the housing device 10b is in a flattened state, the second bending segment 302 is spaced apart from or in non-pressor contact with the support member 120, and is disposed between the support member 120 and the housing body 200. Thus, the second bending segment 302 will not abut against the support member 120, thereby preventing the support member 120 from being lifted and the flexible display screen 10a from being lifted. This ensures that the foldable electronic device 10 has a flat display surface when the housing device 10b is in a flattened state, which is beneficial for improving display quality.

[0076] In some embodiments, when the housing device 10b is in a flattened state, the second bending segment 302 is spaced apart from or in non-pressor contact with the housing body 200, and is disposed between the support member 120 and the housing body 200. Thus, the second bending segment 302 will not press against the housing body 200, and the two will not interfere with each other, causing unnecessary wear. This helps to improve the service life of the transmission component 300 and enhance the durability of the foldable electronic device 10.

[0077] Based on any of the above embodiments, such as 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 frame assembly 110 and the support member 120, and the first bent section 301 enters the receiving space 10c through the gap 114. In this way, the gap 114 facilitates the transmission component 300 to exit from the base frame assembly 110 and enter the receiving space 10c, and also facilitates the avoidance of the first bent section 301.

[0078] Optionally, in some embodiments, a portion of the gap 114 extends through the support surface to form a clearance space 101 for the third transmission body 313. Thus, by utilizing the clearance space 101 to avoid the third transmission body 313, during the bending or stretching of the first bending segment 301 as the third transmission body 313 moves with the hinge mechanism 100, it will not interfere with the base frame assembly 110 or the support member 120, thereby improving the smoothness of movement of the foldable electronic device 10. Furthermore, the first bending segment 301 will not easily wear down, which helps to extend the service life of the transmission assembly 300 and improve the durability of the foldable electronic device 10.

[0079] like Figure 4As shown, in some embodiments, the base frame 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. During the process of switching the housing device 10b to the flattened state, the first guide portion 115 can restrict the third transmission body 313 so that the third transmission body 313 bends to form a first bent segment 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 precision is slightly poor, the guiding and restricting 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 bent segment 301, which helps to reduce the assembly and manufacturing difficulty of the foldable electronic device 10.

[0080] Furthermore, even if the performance of the transmission component 300 is reduced after repeated bending or stretching, the first guide portion 115 can cause the third transmission body 313 to bend toward the support member 120 during the process of switching the housing device 10b to the flattened state, so that the third transmission body 313 can bend smoothly to form the first bending segment 301, so that the housing 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 part 115 can be various, including a guide arc surface or a guide slope.

[0082] Optionally, in some embodiments, the first guide portion 115 includes a first arcuate guide surface 102, which slides in engagement with the third transmission body 313 during the process of switching the housing device 10b to the flattened state. In this way, by fully utilizing the arcuate guiding effect of the first arcuate guide surface 102 and its sliding engagement with the third transmission body 313, the smoothness of the folding movement of the foldable electronic device 10 is improved. Furthermore, the arrangement of the first arcuate guide surface 102 avoids creating sharp angles, thus preventing scratches on the isolation posts and / or other components.

[0083] In some embodiments, when the housing device 10b is in a flattened state, the first guide portion 115 and the first bent section 301 are spaced apart or in non-pressing contact. This reduces the likelihood of wear on the first guide portion 115 and the first bent section 301.

[0084] like Figure 4As shown, in some embodiments, the housing body 200 is provided with a second guide portion. Along the direction from the first fixing portion 113 to the second fixing portion 210, the second guide portion is disposed between the first guide portion 115 and the second fixing portion 210. During the process of switching the housing device 10b to the flattened state, the second guide portion can restrict 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 segments 302. In this way, through the cooperation of the first guide portion 115 and the second guide portion, it is convenient to make full use of the width direction of the foldable electronic device 10 to store at least two second bending segments 302, so that the bending amplitude of the second bending segments 302 is small and it is not easy to interfere with other devices.

[0085] Similarly, the setting of the second guide portion can improve the fault tolerance of the housing device 10b. Even if the error of the relevant parts is large or the manufacturing precision is slightly poor, the stretching third transmission body 313 can be bent into the second bending segment 302 along the set trajectory by the guiding and limiting effect of the second guide portion and the first guide portion 115. This helps to reduce the assembly difficulty and manufacturing difficulty of the foldable electronic device 10.

[0086] Furthermore, even if the performance of the transmission component 300 is reduced after repeated bending or stretching, the second guide portion can restrict the third transmission body 313 during the process of switching the housing device 10b to the flattened state, so that the third transmission body 313 can bend smoothly to form the second bending segment 302, so that the housing component has good display quality when it is in the flattened state.

[0087] like Figure 4 As shown, in some embodiments, the second bending segment 302 includes two segments. One second bending segment 302 is disposed between the first guide portion 115 and the second guide portion, and is connected to the other end of the first bending segment 301, with its bending direction opposite to that of the first bending segment 301. The other second bending segment 302 is disposed between the second guide portion and the second fixing portion 210, and is connected to the second transmission body 312. This allows for better control of the bending direction of the third transmission body 313, reducing the manufacturing difficulty of the transmission assembly 300.

[0088] It should be noted that the specific shape of the second guide part can be varied, including a guide arc surface or a guide slope.

[0089] like Figure 4As shown, in some embodiments, the second guide portion includes a second arc-shaped guide surface, which slides in engagement with the third transmission body 313 during the process of switching the housing device 10b to the flattened state. In this way, by fully utilizing the arc-shaped guiding effect of the second arc-shaped guide surface and its sliding engagement with the third transmission body 313, the occurrence of pressure phenomena is reduced or avoided, preventing wear and improving the smoothness of the folding movement of the foldable electronic device 10. Furthermore, the design of the second arc-shaped guide surface avoids creating sharp angles, thus preventing scratches on the isolation posts and / or other components.

[0090] In some embodiments, when the housing device 10b is in a flattened state, the second guide portion and the second bent section 302 are spaced apart or in non-pressing contact. This reduces the likelihood of wear on the second guide portion and the second bent section 302.

[0091] like Figure 4 As shown, in any embodiment 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 positioned close to the second fixing portion 210. During the process of the housing device 10b switching to a flattened state, the third guide portion 121 can guide the third transmission body 313 and, together with the second guide portion, restrict the bending direction of the third transmission body 313, so that the third transmission body 313 bends to form a second bent segment 302 connected to the second transmission body 312. Thus, through the cooperation of the third guide portion 121 and the second guide portion, the fault tolerance of the housing device 10b can be improved. Even if the errors of related parts are large, or the manufacturing precision is slightly poor, the guiding and restricting effect of the second guide portion and the third guide portion 121 can be used to bend the stretched third transmission body 313 along a set trajectory to form the second bent segment 302, which helps to reduce the assembly and manufacturing difficulty of the foldable electronic device 10.

[0092] Furthermore, even if the performance of the transmission component 300 is reduced after repeated bending or stretching, the third guide portion 121 can restrict the third transmission body 313 during the process of switching the housing device 10b to the flattened state, so that the third transmission body 313 can bend smoothly to form the second bending segment 302, so that the housing component has good display quality when it is in the flattened state.

[0093] It should be noted that the specific shape of the third guide part 121 can be various, including a guide arc surface or a guide slope.

[0094] like Figure 4As shown, in some embodiments, the third guide portion 121 includes a third arc-shaped guide surface, which slides in engagement with the third transmission body 313 during the process of switching the housing device 10b to the flattened state. In this way, by fully utilizing the arc-shaped guiding effect of the third arc-shaped guide surface and its sliding engagement with the third transmission body 313, the occurrence of pressure phenomena is reduced or avoided, preventing wear and tear, while simultaneously improving the smoothness of the folding movement of the foldable electronic device 10. Furthermore, the arrangement of the third arc-shaped guide surface avoids creating sharp angles, thus preventing scratches on the isolation posts and / or other components.

[0095] In some embodiments, when the housing device 10b is in a flattened state, the third guide portion 121 and the second bent section 302 are spaced apart or in non-pressing contact. This reduces the likelihood of wear on the third guide portion 121 and the second bent section 302.

[0096] like Figure 4 As shown, based on any embodiment of the first guide portion 115 described above, in some embodiments, the support member 120 includes a fourth guide portion 122. When the housing device 10b is in a flattened state, the fourth guide portion 122 and the first guide portion 115 are spaced apart to form a gap 114. During the process of the housing device 10b switching to the flattened state, the fourth guide portion 122 can guide the third transmission body 313 and, together with the first guide portion 115, restrict the bending direction of the third transmission body 313 so that the third transmission body 313 bends to form a first bending segment 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 precision is slightly poor, the guiding and restricting effect of the first guide portion 115 and the fourth guide portion 122 can be used to bend the stretched third transmission body 313 along a set trajectory to form the first bending segment 301, which helps to reduce the assembly difficulty and manufacturing difficulty of the foldable electronic device 10.

[0097] Furthermore, even if the performance of the transmission component 300 is reduced after repeated bending or stretching, the fourth guide portion 122 can cause the third transmission body 313 to bend in the opposite direction of the support member 120 during the process of switching the housing device 10b to the flattened state, so that the third transmission body 313 can bend smoothly to form the first bending segment 301, so that the housing component has good display quality when it is in the flattened state.

[0098] It should be noted that the specific shape of the fourth guide part 122 can be various, including a guide arc surface or a guide slope.

[0099] like Figure 4As shown, in some embodiments, the fourth guide portion 122 includes a fourth arc-shaped guide surface, which slides in engagement with the third transmission body 313 during the process of switching the housing device 10b to the flattened state. Thus, by fully utilizing the arc-shaped guiding effect of the fourth arc-shaped guide surface and its sliding engagement with the third transmission body 313, the smoothness of the folding movement of the foldable electronic device 10 is improved. Furthermore, the fourth arc-shaped guide surface avoids creating sharp angles, thus preventing scratches on the isolation posts and / or other components.

[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 bent section 301. This reduces the likelihood of wear between the fourth guide portion 122 and the second bent section 302.

[0101] It should be noted that the first guide part 115, the second guide part, the third guide part 121 or the fourth guide part 122 guide the movement process of the third transmission body 313, which helps to improve the service life of the transmission component 300 and prevents it from easily breaking or making abnormal noises.

[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, forming a rib-like shape. This is beneficial for 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 frame assembly 110, the second fixing portion 210 is closer to the bottom surface 111 than the first fixing portion 113. This facilitates full utilization of the thickness space of the base frame assembly 110, allowing the first bending segment 301 to bend towards the receiving space 10c, thus providing the first bending segment 301 with a larger bending space. This ensures that the first bending segment 301, positioned below the support surface, will not hit the support member 120 and lift the flexible display screen 10a or directly hit the flexible linear display screen.

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

[0105] like Figure 4 as well as Figure 5As shown, in some embodiments, during the process of switching the housing device 10b from a flattened state to a folded state, the first bending segment 301 relative to the bottom surface 111 and the second bending segment 302 connected to the first bending segment 301 are stretched in the opposite direction. This allows the third transmission body 313 to move away from the base frame assembly 110 as the housing body 200 rotates around the base frame assembly 110, so as to better avoid the flexible display screen 10a and facilitate the inward folding of the flexible display screen 10a.

[0106] It should be noted that the first fixing part 113 can be implemented in various ways, including but not limited to screw fixing, adhesive fixing, snap fixing, etc.

[0107] like Figure 4 As shown, in some embodiments, the first fixing part 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 friction force is used to fix the first transmission body 311, which can reduce stress concentration and improve the service life of the transmission assembly 300.

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

[0109] It should be noted that the second fixing part 210 can be implemented in various ways, including but not limited to screw fixing, adhesive fixing, snap fixing, etc.

[0110] like Figure 4 As shown, in some embodiments, the second fixing part 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 assembly 300.

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

[0112] In some embodiments, at least one second clamping member 211 is disposed below the second transmission body 312 relative to the support surface, and a portion of the second clamping member 211 abuts against the second bending segment 302. Thus, by the portion of the second clamping member 211 abutting against the second bending segment 302, the third transmission body 313 is given a reverse guide, preventing the second bending segment 302 from continuing to bend downwards and avoiding compression with the edge of the second clamping member 211, which would be detrimental to improving the durability of the transmission assembly 300.

[0113] Based on any of the above embodiments, in some embodiments, the third transmission body 313 is flexible, and when the third transmission body 313 is in its natural state, it has a first bending segment 301 and at least two second bending segments 302. Thus, the third transmission body 313 can be bent in advance so that when in its natural state, it has the first bending segment 301 and at least two second bending segments 302. That is, when the housing device 10b is in a flattened state, the third transmission body 313 can naturally reset to form the first bending segment 301 and at least two second bending segments 302 to avoid obstructing the movement of related parts, thereby improving durability. During the switching of the housing assembly, the flexibility of the third transmission body 313 allows the first bending segment 301 and the second bending segment 302 to be stretched without easily hindering the movement of the hinge mechanism 100 and the housing body 200.

[0114] like Figure 4 As shown, in some embodiments, the transmission assembly 300 includes at least three transmission members 310 stacked together. Along the thickness direction of the base assembly 110, the first bending segments 301 of the 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 segments 302 of the at least three transmission members 310 are also staggered and stacked along the same direction. Thus, during the movement of the housing device 10b, at least three transmission members 310 will move simultaneously. The lower first bending segment 301 can support the upper first bending segment 301, and the lower second bending segment 302 can support the upper second bending segment 302, making the structure of the transmission assembly 300 more compact and reducing abnormal noise.

[0115] Furthermore, such as Figure 6As shown, in some embodiments, during the process of the housing device 10b switching to the flattened state, among the first bending sections 301 of at least three transmission members 310, the lower first bending section 301 can support the upper first bending section 301. Thus, during the movement of the housing device 10b, at least three transmission members 310 will move simultaneously, facilitating the use of the lower first bending section 301 to support the upper first bending section 301, thereby preventing the upper layer from directly striking the lower layer without any support, resulting in abnormal noises.

[0116] like Figure 7 As shown, in some embodiments, during the process of the housing device 10b switching to the flattened state, among the second bending sections 302 of at least three transmission members 310, the lower second bending section 302 can support the upper second bending section 302. Thus, during the movement of the housing device 10b, at least three transmission members 310 will move simultaneously, facilitating the use of the lower second bending section 302 to support the upper second bending section 302, thereby preventing the upper layer from directly striking the lower layer with no force and producing abnormal noise.

[0117] Based on any of the above embodiments, such as 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 its natural state, it has a first bent segment 301 and at least two second bent segments 302. Thus, the third transmission body 313 is bent using hot pressing technology so that when the third transmission body 313 is in its natural state, it has a first bent segment 301 and at least two second bent segments 302. That is, when the housing device 10b is in a flattened state, the third transmission body 313 can naturally return to its original position to form the first bent segment 301 and at least two second bent segments 302 to avoid obstructing the movement of related parts, thereby improving durability. During the switching of housing components, the third transmission body 313 is flexible enough that the first bent segment 301 and the second bent segment 302 can be stretched without easily hindering the movement of the hinge mechanism 100 and the housing body 200.

[0118] like Figure 4As shown, in some embodiments, the base frame assembly 110 includes a support plate 116, and a first bearing surface 112 is disposed on the support plate 116. When the housing device 10b is in a flattened state, there is a clearance space 101 between the support plate 116 and the support member 120 to avoid the first bending segment 301. Thus, by using the clearance space 101 to avoid the third transmission body 313, during the bending or stretching of the first bending segment 301 as the third transmission body 313 moves with the hinge mechanism 100, there will be no interference with the base frame assembly 110 or the support member 120, which is beneficial to improving the smoothness of movement of the foldable electronic device 10. Furthermore, the first bending segment 301 will not easily wear down, which is beneficial to improving the service life of the transmission assembly 300 and 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 frame assembly 110; the shell body 200 includes two and is symmetrically arranged on both sides of the base frame assembly 110, and moves synchronously towards or away from each other with the two support members 120. The second transmission body 312 and the third transmission body 313 are both two and 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. Furthermore, 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, enabling large-screen display. When the two shell bodies 200 are folded via the hinge mechanism 100, a portion of the flexible display screen 10a bends inward, reducing the display area of ​​the foldable electronic device 10 for easier portability.

[0120] Furthermore, along the thickness direction of the base frame assembly 110, the distance between the second fixing part 210 and the first fixing part 113 of the two shell bodies 200 is equal. This makes the shell bodies 200 and the support member 120 on both sides of the base frame assembly 110 have the same structure and are symmetrically arranged along the axis of symmetry of the base frame assembly 110. This ensures that the bending pattern of the third transmission body 313 on both sides of the base frame assembly 110 is consistent, thereby effectively avoiding unnecessary wear caused by motion interference between the transmission component 300 and the shell body 200, support member 120, base frame assembly 110, or electronic devices, and improving the service life of the foldable electronic device 10.

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

[0122] In some embodiments, the transmission element 310 includes a flexible circuit board and is bent by hot pressing so that when the third transmission body 313 is in its natural state, the third transmission body 313 has a first bending segment 301 and at least two second bending segments 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 part 210. When the shell device 10b is in a flattened state, a portion of the second middle frame is attached to the bottom surface 111. In this way, the shell body 200 is formed by combining the first middle frame 220 and the second middle frame 230, which can reduce the manufacturing difficulty of the shell body 200. When the shell device 10b is in a flattened state, a portion of the second middle frame is attached to the bottom surface 111, making the structure of the foldable electronic device 10 more compact and facilitating the realization of a thinner and lighter foldable electronic device 10.

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

[0125] Optionally, such as Figure 8 As shown, in some embodiments, the linkage assembly 140 includes a synchronizing rod 141 and a first link 142. One end of the synchronizing rod 141 is rotatably connected to the base frame assembly 110, and the other end of the synchronizing rod 141 is slidably connected to the moving member 130. Both ends of the first link 142 are rotatably connected to the base frame assembly 110 and the moving member 130, respectively. This facilitates the formation of a four-bar linkage, allowing the moving member 130 and the support member 120 to rotate around the base frame assembly 110, and the support member 120 to rotate relative to the moving member 130. When the housing device 10b is in a folded state, it forms a clearance recess to avoid the flexible display screen 10a, facilitating the inward folding of the flexible display screen 10a.

[0126] Optionally, such as Figure 9 as well as Figure 10As shown, in other embodiments, the linkage 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 frame assembly 110, and the second linkage assembly 140 is rotatably connected to the base frame 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 both the base frame assembly 110 and the transmission member 143, and is slidably connected to the moving member 130. Thus, during the transition of the foldable electronic device 10 from a folded state to an open state, the hinge mechanism 100 also transitions from a folded state to an unfolded state. The connecting rod assemblies 140 on both sides of the base frame assembly 110 rotate around the base frame assembly 110. When the first connecting rod assembly 142 and the second connecting rod assembly 140 rotate synchronously along the base frame assembly 110, the third rotating member 146 drives the moving member 130 to rotate. Simultaneously, the first rotating member 144 and the transmission member 143 transmit power synchronously, causing the second rotating member 145 to rotate in a set direction. This causes the moving member 130 to slide along the length of the second guide portion and move closer to the base frame assembly 110. At this time, as the support member 120 moves with the moving member 130, it unfolds towards a supporting state until the support member 120 mates with the third bearing surface to form a supporting structure, thereby supporting the flexible display screen 10a. When the foldable electronic device 10 switches from the open state to the folded state, the hinge mechanism 100 also switches from the unfolded state to the folded state. This allows the first connecting rod 142 assembly 140 and the third rotating member 146 to rotate along the base frame assembly 110. Simultaneously, the third rotating member 146 drives the moving member 130 to rotate, while the first rotating member 144 and the transmission member 143 are synchronously driven, causing the second rotating member 145 to rotate in a set direction. This causes the moving member 130 to slide along the length of the second guide portion and move away from the base frame assembly 110. During this time, as the support member 120 moves with the moving member 130, it is angled relative to the third bearing surface to form a clearance recess until the foldable electronic device 10 is in the folded state. This allows a portion of the flexible display screen 10a to bend within the clearance recess, reducing bending stress on the flexible display screen 10a and improving its lifespan.

[0127] It should be noted that foldable electronic devices include handheld display devices, in-vehicle display devices, monitoring display devices, cellular phones, smartphones, tablets, televisions, monitors, laptops, laptop computers, cameras, video recorders, cameras, smartwatches, smart wristbands, in-vehicle computers, and other electronic devices with imaging capabilities.
