[0002] With the continuous development of flexible display technology, some device manufacturers provide foldable electronic devices for users to choose. The hinge mechanism of the current foldable electronic device includes a base and a pair of distributed rotating assemblies arranged on both sides of the base. Among them, the rotating assembly includes a first rotating piece and a support piece. In the case that the electronic device is in a folded state, the support piece and the base enclose a "water drop-shaped" screen containing space, which is used to contain the flexible display area of the display screen of the electronic device.

DETAILED DESCRIPTION

[0024] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in conjunction with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort shall fall within the scope of protection of the present application.

[0025] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection" and "linking" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] In addition, although the terms used in the present application are selected from the commonly known and used terms, some terms mentioned in the description of the present application may be selected by the applicant according to his or her judgment, and the detailed meanings of which are described in the relevant parts of the description.

[0027] In addition, the present application should be understood not only by the actual terms used, but also by the meaning implied by each term.

[0028] The technical solutions provided by the embodiments of the present application are described in detail below with reference to the drawings.

[0029] The embodiment of the present application provides a hinge mechanism. Referring to Figures 1 to 23 The hinge mechanism 10 provided by the embodiment of the present application comprises a base 100 and a pair of distributed rotating assemblies 200 arranged on both sides of the base 100.

[0030] The rotating assembly 200 comprises a first rotating piece 210, a connecting bracket 220 and a supporting piece 230. One end of the first rotating piece 210 is rotationally connected with the base 100 through a rotating shaft 300, and the other end of the first rotating piece 210 is slidingly and matchingly connected with the connecting bracket 220. The first rotating piece 210 is provided with a first stop portion 211.

[0031] The supporting piece 230 is rotationally connected with the connecting bracket 220. The supporting piece 230 is provided with a second stop portion 231. In the case that the hinge mechanism 10 is in a folded state, the second stop portion 231 is opposite to the first stop portion 211, and the distance between the first stop portion 211 and the second stop portion 231 is less than a first threshold value.

[0032] It should be noted that the value range of the first threshold value can be flexibly set according to requirements, as long as, in the case that the hinge mechanism 10 in the folded state is impacted, the second stop portion 231 and the first stop portion 211 can be stop matched after the supporting piece 230 moves a preset distance relative to the first rotating piece 210 in the direction close to the base 100, so that the supporting piece 230 continues to move in the direction close to the base 100 relative to the first rotating piece 210.

[0033] In this way, in the embodiment of the present application, in the case that the hinge mechanism 10 is in a folded state, the second stop portion 231 is opposite to the first stop portion 211, and the distance between the first stop portion 211 and the second stop portion 231 is less than a first threshold value; in the case that the hinge mechanism in the folded state is impacted, the second stop portion 231 and the first stop portion 211 are stop matched after the supporting piece 230 moves a preset distance relative to the first rotating piece 210 in the direction close to the base 100, so that the supporting piece 230 continues to move in the direction close to the base 100 relative to the first rotating piece 210, and thus the excessive deflection of the supporting piece 230 can be avoided.

[0034] In addition, in the case that the hinge mechanism 10 is arranged in the electronic device 1, and the electronic device 1 comprises a display screen 40, the excessive deflection of the supporting piece 230 can be avoided in the case that the electronic device 1 in the folded state is impacted, and the part of the display screen 40 accommodated in the screen accommodating space surrounded by the supporting piece 230 and the base 100 is pressed, so that the display screen 40 can be prevented from being damaged.

[0035] It should be noted that the reference is... Figure 3 and Figure 4 ,by Figure 4 Taking the orientation shown as an example, the lower end of the support member 230 is opposite to the stepped portion of the first rotating member 210. However, the lower end of the support member 230 and the stepped portion of the first rotating member 210 do not have the function of blocking when subjected to impact. The specific reasons are explained below.

[0036] Combination Figures 3 to 6 When the distance between the lower end of the support member 230 and the stepped portion of the first rotating member 210 is small, the lower end of the support member 230 will interfere with the stepped portion of the first rotating member 210 during the initial opening phase when the hinge mechanism 10 switches from the folded state to the open state. Therefore, to avoid interference between the lower end of the support member 230 and the stepped portion of the first rotating member 210 during the initial opening phase when the hinge mechanism 10 switches from the folded state to the open state, the distance between the lower end of the support member 230 and the stepped portion of the first rotating member 210 needs to be large.

[0037] Furthermore, when the distance between the lower end of the support member 230 and the stepped portion of the first rotating member 210 is large, the lower end of the support member 230 and the stepped portion of the first rotating member 210 do not have the function of stopping the impact. Therefore, the function of the lower end of the support member 230 is different from the function of the second stop portion 231 of the support member 230, and the function of the stepped portion of the first rotating member 210 is different from the function of the first stop portion 211 of the first rotating member 210.

[0038] refer to Figures 3 to 8 , or refer to Figures 9 to 14 , or refer to Figures 15 to 20 In some embodiments, the first stop 211 includes a stop surface 2111 and an abutment surface 2112. When the hinge mechanism 10 is in the folded state, the second stop 231 is opposite to the stop surface 2111. The support member 230 is provided with a first curved surface 232. During the process of the hinge mechanism 10 switching from the folded state to the unfolded state, the abutment surface 2112 abuts against the first curved surface 232 to drive the support member 230 to rotate relative to the connecting bracket 220.

[0039] It is understandable that when the hinge mechanism 10 is in the folded state, the two opposing support members 230 and the base 100 form a screen-accommodating space. Figure 5The shown orientation is an example. Since the screen containing space is in a structure of small at the top and large at the bottom, the skilled in the art also calls the screen containing space surrounded by the support 230 and the base 100 as a "water drop-shaped" screen containing space. In this way, the flexible display area of the display screen 40 of the electronic device 1 provided with the hinge mechanism 10 is accommodated in the screen containing space. It should be noted that the flexible display area of the display screen 40 refers to the area of the display screen 40 that is flexibly bent and deformed during the switching of the electronic device 1 from the unfolded state to the folded state. In addition, when the hinge mechanism 10 is in the unfolded state, the side of the two supports 230 away from the corresponding first rotating piece 210 is flush, so as to support the flexible display area of the display screen 40.

[0040] In this way, by means of the mode that the first rotating piece 210 drives the support 230 to rotate relative to the connecting bracket 220 through the abutting surface 2112 during the switching of the hinge mechanism 10 from the folded state to the unfolded state, the side of the two supports 230 away from the corresponding first rotating piece 210 is switched to the state of being flush with each other, so as to provide support force to the flexible display area of the display screen 40, so as to avoid the collapse and deformation of the flexible display area of the display screen 40 during the user touching the flexible display area of the display screen 40.

[0041] In some embodiments, the second stop portion 231 is a first plane, and when the first plane is in abutment with the stop surface 2111, the first plane is tangent to the stop surface 2111. In other words, when the hinge mechanism 10 is impacted and the first plane is in abutment with the stop surface 2111, the first plane is tangent to the stop surface 2111, so that the stop surface 2111 can better support the second stop portion 231, so as to avoid the second stop portion 231 sliding relative to the stop surface 2111 when the first plane is in abutment with the stop surface 2111.

[0042] It should be noted that, Figures 1 to 8 The hinge mechanism 10 shown in the middle is in hard contact between the first stop portion 211 of the first rotating piece 210 and the second stop portion 231 of the support 230 when impacted, and there is a lack of effective buffering therebetween. In order to further improve the anti-impact effect of the hinge mechanism 10, the present application provides another hinge mechanism 10.

[0043] Reference Figures 9 to 20 In some embodiments, the support 230 includes a body 233 and a supporting plunger 234. The body 233 is provided with a first accommodating hole 2331, the supporting plunger 234 is in sliding fit connection with the hole wall of the first accommodating hole 2331, and the second stop portion 231 is located at the supporting plunger 234. The side of the supporting plunger 234 away from the second stop portion 231 surrounds a plunger cavity 235 with the hole wall of the first accommodating hole 2331.

[0044] Thus, when the hinge mechanism 10 is impacted, the first stop portion 211 of the first rotating member 210 pushes against the second stop portion 231 of the supporting plunger 234, so as to compress the plunger cavity 235. For example, when there is gas or liquid in the plunger cavity 235, the gas or liquid in the plunger cavity 235 can play a buffering role, so as to avoid the hard contact between the first stop portion 211 of the first rotating member 210 and the second stop portion 231 of the supporting member 230.

[0045] Referring to Figure 9 and Figure 10 , alternatively, referring to Figure 15 and Figure 16 , in some embodiments, the body 233 is further provided with a damping hole 2332 which is in communication with the plunger cavity 235. Thus, when the hinge mechanism 10 is impacted, the supporting plunger 234 is driven by the first stop portion 211 of the first rotating member 210 to move away from the first stop portion 211 of the first rotating member 210, the gas or liquid in the plunger cavity 235 is discharged into the damping hole 2332, and the damping hole 2332 can consume part of the impact energy, so as to improve the buffering effect of the supporting plunger 234.

[0046] Referring to Figure 9 and Figure 10 , in some embodiments, the body 233 is further provided with a curved pipe, the plunger cavity 235 is in communication with the outside of the body 233 through the curved pipe, and the curved pipe forms the damping hole 2332. Thus, by the way of forming the damping hole 2332 through the curved pipe, the buffering effect of the supporting plunger 234 can be improved.

[0047] Referring to Figure 15 and Figure 16 , in some embodiments, the body 233 is further provided with a storage cavity 2333. The plunger cavity 235 is in communication with the storage cavity 2333 through the damping hole 2332. Thus, when there is more liquid in the plunger cavity 235, when the hinge mechanism 10 is impacted, the supporting plunger 234 is driven by the first stop portion 211 of the first rotating member 210 to move away from the first stop portion 211 of the first rotating member 210, and a small amount of liquid in the plunger cavity 235 is discharged through the damping hole 2332 and can be collected in the storage cavity 2333.

[0048] Referring to Figure 15 and Figure 16In some embodiments, the body 233 is further provided with a second accommodating hole 2334. A sealing plug 2335 is arranged in the second accommodating hole 2334, and the sealing plug 2335 and the hole wall of the second accommodating hole 2334 form a storage cavity 2333. The sealing plug 2335 is provided with a through hole 2336, and the storage cavity 2333 is in communication with the outside of the body 233 through the through hole 2336. In this way, when the plunger cavity 235 contains a large amount of liquid, the hinge mechanism 10 is impacted, the support plunger 234 is driven by the first stop portion 211 of the first rotating member 210 to move away from the first stop portion 211 of the first rotating member 210, and a small amount of liquid in the plunger cavity 235 is discharged through the damping hole 2332, the small amount of liquid can be collected in the storage cavity 2333. Further, since the storage cavity 2333 is in communication with the outside of the body 233 through the through hole 2336, the gas in the storage cavity 2333 can be discharged to the outside of the storage cavity 2333 through the through hole 2336, so that the small amount of liquid in the plunger cavity 235 can better enter the storage cavity 2333.

[0049] In some embodiments, the support member 230 further comprises a reset member 236, which is used to locate the support plunger 234 in the extended position when the hinge mechanism 10 is in the folded state. For example, when the support plunger 234 is in the extended position, the second stop portion 231 arranged on the end surface of the support plunger 234 abuts against the first stop portion 211 of the first rotating member 210. In this way, when the hinge mechanism 10 is impacted, the support plunger 234 can block the displacement of the support member 230 together with the first stop portion 211 of the first rotating member 210.

[0050] It should be noted that the support plunger 234 does not completely limit the displacement of the support member 230 during the blocking of the displacement of the support member 230, but the support plunger 234 is slowly retracted under the buffering action of the gas or liquid in the plunger cavity 235 at the back, so that the support member 230 is slowly displaced, and after moving a distance, the gas or liquid in the plunger cavity 235 will consume the impact energy under the action of the damping hole 2332, so that the displacement of the support member 230 is stopped.

[0051] Reference Figure 15 and Figure 16In some embodiments, the reset member 236 is a magnetic member, and the reset member 236 is fixedly connected to the support plunger 234. When the hinge mechanism 10 is in the folded state, the reset member 236 is magnetically adsorbed to the position where the first stop portion 211 of the first rotating member 210 is located. For example, the position where the first stop portion 211 of the first rotating member 210 is located is made of a material that can be magnetically adsorbed by a magnetic member. For example, the position where the first stop portion 211 of the first rotating member 210 is located is made of iron or an alloy of iron. Alternatively, the position where the first stop portion 211 of the first rotating member 210 is located is provided with a magnet.

[0052] In this way, when the hinge mechanism 10 is in the folded state, the reset member 236 causes the second stop portion 231 of the end surface of the support plunger 234 to abut against the first stop portion 211 of the first rotating member 210, so as to improve the impact resistance effect.

[0053] Reference Figures 15 to 20 In some embodiments, the body 233 is provided with a second curved surface 2337 and a first limiting surface 2338. The support plunger 234 is provided with a third curved surface 2341 and a second limiting surface 2342. When the support plunger 234 is in the retracted position, the second limiting surface 2342 abuts against the first limiting surface 2338, and the third curved surface 2341 and the second curved surface 2337 are spliced into the first curved surface 232. The first stop portion 211 includes an abutting surface 2112, which abuts against the first curved surface 232 during the switching of the hinge mechanism 10 from the folded state to the unfolded state, so as to drive the support member 230 to rotate relative to the connecting bracket 220.

[0054] In this way, when the hinge mechanism 10 is in the folded state, the support plunger 234 can play a buffering role when the hinge mechanism 10 is impacted, so as to eliminate the influence of the impact force. During the switching of the hinge mechanism 10 from the folded state to the unfolded state, the first stop portion 211 drives the support plunger 234 to retract until the second limiting surface 2342 abuts against the first limiting surface 2338. At this time, the third curved surface 2341 and the second curved surface 2337 are spliced into the first curved surface 232 when the second limiting surface 2342 abuts against the first limiting surface 2338.

[0055] Further, during the switching process of the hinge mechanism 10 from the folded state to the unfolded state, the abutting surface 2112 of the first stop portion 211 can abut against the first curved surface 232. Thus, by pushing the first curved surface 232 of the support member 230 in the process of the rotation of the first rotating member 210 relative to the base 100, the support member 230 is driven to rotate relative to the connecting bracket 220, so that the two support members 230 switch to the state of being flush with each other on the side away from the corresponding first rotating member 210, thereby providing support force to the flexible display area of the display screen 40 to avoid deformation of the flexible display area of the display screen 40 in the process of the user touching the flexible display area of the display screen 40.

[0056] It should be noted that, with reference to Figures 3 to 8 In the hinge mechanism 10 provided in this embodiment, the first curved surface 232 of the support member 230 is provided with an avoiding recess on the side, and the side wall of the avoiding recess forms the second stop portion 231 for stop cooperation with the first stop portion 211 of the first rotating member 210. In this way, when the avoiding recess is provided on the side of the first curved surface 232, part of the first curved surface 232 is removed, so that the first stop portion 211 of the first rotating member 210 cannot contact the starting segment of the first curved surface 232. Further, in the initial opening process of the hinge mechanism 10, the first stop portion 211 of the first rotating member 210 cannot abut against the first curved surface 232, so that the support member 230 cannot be supported, and the support member 230 will sway.

[0057] With reference to Figures 9 to 20 In the hinge mechanism 10 provided in this embodiment, the support member 230 is provided with a support plunger 234, the support plunger 234 is provided with a third curved surface 2341 and a second limiting surface 2342, the body 233 of the support member 230 is provided with a second curved surface 2337 and a first limiting surface 2338, and in the initial opening state of the hinge mechanism 10, the first stop portion 211 drives the support plunger 234 to retract until the second limiting surface 2342 abuts against the first limiting surface 2338. When the second limiting surface 2342 abuts against the first limiting surface 2338, the third curved surface 2341 and the second curved surface 2337 are spliced into the first curved surface 232.

[0058] Further, during the switching process of the hinge mechanism 10 from the folded state to the unfolded state, the abutting surface 2112 of the first stop portion 211 can abut against the first curved surface 232. Thus, by pushing the first curved surface 232 of the support member 230 in the process of the rotation of the first rotating member 210 relative to the base 100, the support member 230 is driven to rotate relative to the connecting bracket 220, so that the two support members 230 switch to the state of being flush with each other on the side away from the corresponding first rotating member 210, thereby providing support force to the flexible display area of the display screen 40 to avoid deformation of the flexible display area of the display screen 40 in the process of the user touching the flexible display area of the display screen 40.

[0059] Further, in the case that the reset member 236 provided on the supporting plunger 234 is a magnetic member, and the reset member 236 is used to magnetically attract and cooperate with the position where the first stop portion 211 of the first rotating member 210 is located, in the case that the hinge mechanism 10 is opened by a certain angle, the first stop portion 211 of the first rotating member 210 is misaligned with the supporting plunger 234, and the first stop portion 211 of the first rotating member 210 is in abutment with the second curved surface 2337 of the body 233, since the first rotating member 210 is misaligned with the supporting plunger 234, the supporting plunger 234 will not automatically extend. In this way, the second limiting surface 2342 and the first limiting surface 2338 can be kept in the state of abutment and cooperation, and thus the third curved surface 2341 and the second curved surface 2337 can be kept in the state of splicing into the first curved surface 232.

[0060] Further, in the process of switching the hinge mechanism 10 from the unfolded state to the folded state, the first stop portion 211 of the first rotating member 210 can be smoothly switched from the state of abutment with the second curved surface 2337 of the body 233 to the state of abutment with the third curved surface 2341 of the supporting plunger 234, so as to avoid the gap between the second curved surface 2337 of the body 233 and the third curved surface 2341 of the supporting plunger 234 due to the automatic extension of the supporting plunger 234 in the process of switching the hinge mechanism 10 from the unfolded state to the folded state, so that the first stop portion 211 of the first rotating member 210 is not smoothly switched between the second curved surface 2337 of the body 233 and the third curved surface 2341 of the supporting plunger 234.

[0061] Of course, in some embodiments, in the case that the switching smoothness of the first stop portion 211 of the first rotating member 210 between the second curved surface 2337 of the body 233 and the third curved surface 2341 of the supporting plunger 234 is not required to be high, the reset member 236 can not be set as a magnetic member. For example, an elastic element can be used as the reset member 236.

[0062] Reference Figure 1 , Figures 21 to 23 In some embodiments, the rotating assembly 200 further comprises a second rotating member 240. The second rotating member 240 comprises a bearing portion 241. The base 100 is provided with a bearing groove, and the bearing portion 241 is slidingly connected to the bearing groove, so as to be rotationally connected to the base 100 about the axis of the bearing groove.

[0063] It should be noted that in some embodiments, the first rotating member 210 is rotatably connected to the base 100 through the rotating shaft 300, and the second rotating member 240 is rotatably connected to the base 100 in a manner that the second rotating member 240 is slidingly connected to the bearing groove of the base 100 through the bearing part 241. Since no physical rotating shaft is arranged between the second rotating member 240 and the base 100, the second rotating member 240 can be referred to as a "virtual swing arm". In addition, the first rotating member 210 can be referred to as a "synchronous swing arm".

[0064] With reference to Figures 1 to 22 The electronic device provided by the embodiment of the present application comprises a first frame 20, a second frame 30, a display screen 40 and any one of the hinge mechanisms 10 provided by the embodiment of the present application.

[0065] The first frame 20 is fixedly connected to one of the connecting supports 220, the second frame 30 is fixedly connected to the other connecting support 220, the display screen 40 comprises a first display area, a flexible display area and a second display area, the first display area is connected to the first frame 20, the second display area is connected to the second frame 30, and the flexible display area is opposite to the supporting member 230.

Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that processes, methods, articles or devices including a series of elements not only include those elements, but also include other elements not explicitly listed or inherent to such processes, methods, articles or devices.
