Hinge and electronic device

Abstract

This application discloses a hinge and an electronic device, belonging to the field of electronic device technology. The hinge includes a support base and at least two flipping components. During the transition of the hinge from an unfolded state to a folded state, the distance between the two second support plates of the two flipping components, which are arranged opposite each other on both sides of the support base, gradually increases, reaching its maximum distance when the hinge is in the folded state. This results in a larger space between the support base and the foldable display screen when the hinge is in the folded state. Therefore, if the electronic device with this hinge is in the folded state and falls, causing the hinged side to contact the ground, the probability of the support base, which moves towards the foldable display screen due to the impact force, squeezing the foldable display screen is low, thus reducing the probability of damage to the foldable display screen and improving the reliability of the electronic device with this hinge.

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0059] The hinge provided in this application embodiment can be applied to foldable electronic devices. Under different usage conditions, users can fold or unfold the foldable electronic device to meet their different needs. For example, when a user needs to carry the foldable electronic device with them, they can fold it to reduce its size and improve portability; when a user needs to use the foldable electronic device, they can unfold it to provide a larger display area and operating area, thereby improving ease of use. In practical applications, foldable electronic devices can be of various types, such as mobile phones, tablets, laptops, or e-readers.

[0060] Taking a mobile phone as an example, a mobile phone may include a first housing and a second housing connected by a hinge, allowing relative rotation between the first and second housings under the action of the hinge. A foldable display screen can be disposed on the surface of the first and second housings. When the mobile phone is unfolded, the foldable display screen can provide a larger display area and operating area to improve usability. When the mobile phone is folded, it is not only easy to carry, but also allows the use of the folded display screen. The following embodiments will describe in detail the structure of the hinge in the foldable display device.

[0061] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a hinge structure provided in an embodiment of this application. The hinge 000 may include: a support base 100 and at least two flipping components 200.

[0062] The support base 100 in hinge 000 can extend along a first direction X. At least two flip-up components 200 in hinge 000 are rotatably connected to the support base 100, and when hinge 000 is in the extended state, the at least two flip-up components 200 can be positioned opposite each other on both sides of the support base 100 in a second direction Y. Here, the first direction X can intersect with the second direction Y; for example, the first direction X can intersect the second direction Y perpendicularly.

[0063] like Figure 2 As shown, Figure 2 This is a schematic diagram of another hinge structure provided in an embodiment of this application. The flipping assembly 200 may include: a first support plate 201, a second support plate 202, and a rotating shaft component 203. The rotating shaft component 203 can be rotatably connected to the support base 100 and can be fixedly connected to the first support plate 201. One side of the second support plate 202 can be rotatably connected to one side of the first support plate 201. Thus, during the rotation of the rotating shaft component 203 relative to the support base 100, the rotating shaft component 203 can drive the first support plate 201 to rotate relative to the support base 100, while the first support plate 201 can drive the second support plate 202 to rotate relative to the support base 100.

[0064] like Figure 2 and Figure 3 As shown, Figure 3 This is a schematic diagram illustrating the switching of a hinge between a folded and unfolded state according to an embodiment of this application. When the hinge 000 is in the unfolded state, the first support surface P1 of the first support plate 201 and the second support surface P2 of the second support plate 202 in the flip assembly 200 can both be used to support the foldable display screen. Furthermore, when the hinge 000 is in the unfolded state, in the second direction Y, among the two flip assemblies 200 arranged opposite each other on both sides of the support base 100, the second support plate 202 in one flip assembly 200 can be closer to the other flip assembly 200 relative to the first support plate 201. The entire second support plate 202 can be used to cover the support base 100, and the edge portion of the first support plate 201 on the side opposite to the second support plate 202 can also be used to cover the support base 100. When the hinge 000 is in the folded state, the first support surfaces P1 of the two first support plates 201 in the two flip assemblies 200 arranged opposite each other on both sides of the support base 100 can be arranged opposite each other.

[0065] And such as Figure 3 As shown, during the transition of hinge 000 from the unfolded state to the folded state, the distance between the two second support plates 202 of the two flip components 200 arranged opposite each other on both sides of the support base 100 gradually increases. Here, when hinge 000 is in the unfolded state, the distance between the two second support rods 202 of the two flip components 200 arranged opposite each other on both sides of the support base 100 is the smallest, and when hinge 000 is in the folded state, the distance between the two second support plates 202 of the two flip components 200 arranged opposite each other on both sides of the support base 100 is the largest.

[0066] It should be noted that in existing technology, the second support plate in the hinge is fixedly connected to the support base. Thus, regardless of whether the hinge is in the unfolded or folded state, the second support plate is always located between the foldable display and the support base, meaning it will always occupy the space between them. Consequently, if the foldable electronic device with the hinge is in the folded state and falls, the hinged side will be subjected to impact force upon contact with the ground. Under this impact, the support base will move the second support plate towards the foldable display, increasing the probability of the second support plate squeezing the display and thus increasing the likelihood of damage. This results in lower reliability for foldable electronic devices with this hinge.

[0067] In this application, during the transition of the hinge 000 from an unfolded state to a folded state, the distance between the two second support plates 202 of the two flip components 200 arranged opposite each other on both sides of the support base 100 gradually increases, and the distance between the two second support plates 202 of the two flip components 200 arranged opposite each other on both sides of the support base 100 is at its maximum after the hinge is in the folded state. Thus, when the hinge 000 is in the folded state, the space between the support base 100 and the foldable display screen is relatively large. Therefore, when the foldable electronic device with the hinge installed is in the folded state, if the foldable electronic device falls, the probability of the support base 100, which is subjected to impact force and moves towards the foldable display screen, squeezing the foldable display screen when the side of the foldable electronic device with the hinge 000 contacts the ground is low, thereby reducing the probability of damage to the foldable display screen and improving the reliability of the foldable electronic device with the hinge 000 installed.

[0068] In summary, this application provides a hinge comprising a support base and at least two flipping components. During the hinge's transition from an unfolded state to a folded state, the distance between the two second support plates of the two flipping components positioned opposite each other on both sides of the support base gradually increases, reaching its maximum distance when the hinge is in the folded state. This results in a larger space between the support base and the foldable display screen when the hinge is in the folded state. Therefore, when a foldable electronic device equipped with this hinge is in the folded state, if the device falls and the hinge-equipped side contacts the ground, the probability of the support base, which moves towards the foldable display screen, being subjected to impact force and causing pressure on the display screen is low, thus reducing the probability of damage to the display screen and improving the reliability of the foldable electronic device equipped with this hinge.

[0069] Optional, such as Figure 4 As shown, Figure 4 This is a schematic diagram of another hinge structure provided in this application embodiment. The support base 100 in the hinge 000 may include: a base body 101 rotatably connected to the pivot component 203, and an end cap 102 fixedly connected to the base body 101. It should be noted that the end cap 102 in the support base 100 is located on the side of the base body 101 facing away from the foldable display screen. The side of the end cap 102 facing away from the base body 101 is the part that the user can directly observe after the hinge 000 is installed in the foldable electronic device. The end cap 102 in the support base 100 can protect and beautify the base body 101.

[0070] Furthermore, the base body 101 of the support base 100 may have a first arcuate surface A1 on the side facing away from the end cap 102. During the switching between the unfolded and folded states of the hinge 000, the side of the second support plate 202 facing away from the first support plate 201 may contact the first arcuate surface A1 of the base body 101. Thus, during the rotation of the first support plate 201 relative to the support base 100, the second support plate 202, rotatably connected to the first support plate 201, can rotate relative to the first support plate 201 due to the abutment action of the first arcuate surface A1 on the side of the second support plate 202 facing away from the first support plate 201, and the rotation trajectory of the second support plate 202 may be identical to the arc of the first arcuate surface A1.

[0071] It should be noted that the first arcuate surface A1 of the base body 101 can be a concave surface of the base body 101 along the direction of the base body 101 toward the end cap 102. That is, the center of curvature of the first arcuate surface A1 can be located on the side of the base body 101 away from the end cap 102. Furthermore, in the second direction Y, the first arcuate surface A1 can include two completely symmetrical parts. The two second support plates 202 of the two flipping components 200 arranged opposite each other on both sides of the support base 100 are respectively away from the corresponding first support plate 201 and can respectively contact the two completely symmetrical parts of the first arcuate surface A1. Moreover, in the portion of the first arcuate surface A1 corresponding to the second support plate 202 of a flipping component 200, the distance between the first arcuate surface A1 and the end cap 102 can gradually increase along the direction of the second support plate 202 toward the first support plate 201.

[0072] Thus, during the transition of hinge 000 from the unfolded state to the folded state, under the combined action of the first support plate 201 and the first arc-shaped surface A1, the distance between the two second support plates 202 of the two flip-up components 200 arranged opposite each other on both sides of the support base 100 can gradually increase, so that the second support plates 202 gradually no longer cover the support base 100, thereby gradually increasing the space between the support base 100 and the folding display screen. During the transition of hinge 000 from the folded state to the unfolded state, under the combined action of the first support plate 201 and the first arc-shaped surface A1, the distance between the two second support plates 202 of the two flip-up components 200 arranged opposite each other on both sides of the support base 100 can gradually decrease, and the second support plates 202 can gradually cover the support base 100.

[0073] Optional, such as Figure 5 As shown, Figure 5This is a partial exploded view of a hinge provided in an embodiment of this application. The pivot component 203 in the flip assembly 200 may include a track rod 2031 and a first rotating part 2032. The track rod 2031 in the pivot component 203 can be rotatably connected to the base body 101, and the first rotating part 2032 can be rotatably connected to the track rod 2031 and fixedly connected to the first support plate 201. In this way, the pivot component 203 can be rotatably connected to the base body 101 through the track rod 2031, and can drive the first support plate 201 to rotate relative to the base body 101 through the first rotating part 2032.

[0074] Here, the end of the track rod 2031 facing the base body 101 can be rotatably connected to the base body 101. The rotating shaft component 203 may also include a second support shaft 2035, the end of the track rod 2031 away from the base body 101 can be rotatably connected to the second support shaft 2035, and the end of the first rotating part 2032 facing the track rod 2031 can be rotatably connected to the second support shaft 2035. Therefore, the track rod 2031 and the first rotating part 2032 can be rotatably connected via the second support shaft 2035. In addition, the first rotating part 2032 can be fixedly connected to the first support plate 201 by means of screws, riveting, bonding, or injection molding.

[0075] Optional, such as Figure 5 and Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of a trajectory rod provided in an embodiment of this application. The base body 101 in the support 100 may also have a first arc-shaped groove H1 on the side facing away from the end cover 102. The end of the trajectory rod 2031 in the rotating shaft component 203 facing the base body 101 may be distributed at least within the first arc-shaped groove H1 to be rotatably connected to the base body 101.

[0076] It should be noted that the first arc-shaped groove H1 of the base body 101 may have two arc-shaped limiting grooves H11 arranged opposite each other in the first direction X. The end of the track rod 2031 facing the base body 101 may have two first arc-shaped sliding plates 20311. The two first arc-shaped sliding plates 20311 of the track rod 2031 are distributed on both sides of the track rod 2031 arranged opposite each other in the first direction X. The two first arc-shaped sliding plates 20311 may be located in the two arc-shaped limiting grooves H11 respectively to realize the rotational connection between the track rod 2031 and the base body 101.

[0077] The side of the second support plate 202 in the flip assembly 200 that is opposite to the second support surface P2 may have a first clearance groove S1. When the hinge is in the unfolded state, a portion of the track rod 2031 lies outside the first arc-shaped slide groove H1. For two flip assemblies 200 arranged opposite each other in the second direction Y, the portion of the track rod 2031 in one flip assembly 200 that lies outside the first arc-shaped slide groove H1 may at least lie within the first clearance groove S1 of the second support plate 202 in the other flip assembly 200. Thus, when the hinge 000 is in the unfolded state, the track rod 2031 will not interfere with the second support plate 202, allowing the hinge 000 to move normally.

[0078] Optional, such as Figure 5 , Figure 6 and Figure 7 , Figure 7 This is an exploded view of a first support plate and a second support plate provided in an embodiment of this application. The flipping assembly 200 may further include a rotatable connection portion 204 located between the first support plate 201 and the second support plate 202, wherein one side of the first support plate 201 can be rotatably connected to one side of the second support plate 202 via the rotatable connection portion 204. The track rod 2031 in the pivot component 203 may have a second clearance groove S2 on the side facing away from the base body 101. Wherein, when the hinge is in the folded state, at least a portion of the rotatable connection portion 204 may be located within the second clearance groove S2 of the track rod 2031. Thus, when the hinge 000 is in the folded state, the track rod 2031 will not interfere with the rotatable connection portion 204, allowing the hinge 000 to move normally.

[0079] Optional, such as Figure 7 As shown, the rotating connection portion 204 may include a connecting body 2041 and a connecting shaft 2042. The connecting body 2041 in the rotating connection portion 204 may be fixedly connected to the side of the first support plate 201 facing the second support plate 202, and the connecting shaft 2042 in the rotating connection portion 204 may be connected to the connecting body 2041. The side of the second support plate 202 facing the first support plate 201 may be rotatably connected to the connecting shaft 2042.

[0080] It should be noted that, as Figure 7As shown, the side of the first support plate 201 facing the second support plate 202 may have a positioning hole M1, and the end of the connecting body 2041 facing the first support plate 201 may have a positioning post 2043. The positioning post 2043 in the connecting body 2041 may be located in the positioning hole M1 of the first support plate 201 to achieve a fixed connection between the connecting body 2041 and the first support plate 201. Furthermore, the side of the second support plate 202 facing the first support plate 201 may have a through hole, through which the second support plate 202 can be sleeved on the connecting shaft 2042 to achieve a rotatable connection between the second support plate 202 and the connecting shaft 2042.

[0081] Optional, such as Figure 3 and Figure 7 As shown, the flipping assembly 200 may include at least two rotating shaft components 203 arranged in the first direction X. The first support plate 201 may include at least two first support bodies 2011 and at least one second support body 2012. The at least two first support bodies 2011 in the first support plate 201 may be fixedly connected to the at least two rotating shaft components 203 in a one-to-one correspondence. Furthermore, two adjacent first support bodies 2011 distributed in the first direction X may be fixedly connected through a second support body 2012. Similarly, the second support plate 202 may include at least two third support bodies 2021 and at least one fourth support body 2012. The at least two third support bodies 2021 in the second support plate 202 may be rotatably connected to the at least two first support bodies 2011 in a one-to-one correspondence. Furthermore, two adjacent third support bodies 2021 distributed in the first direction X may be fixedly connected through a fourth support body 2022.

[0082] In this application, after the hinge is in the unfolded state, since the second support surface P2 of the second support plate 202 is used to support the foldable display screen, the user may apply pressure to the side of the second support plate 202 away from the first support plate 201 during the use of the foldable electronic device. Therefore, to prevent the side of the second support plate 202 away from the first support plate 201 from moving towards the base body 101 after the hinge is in the unfolded state, which would result in poor flatness of the foldable display screen, it is necessary to restrict the movement of the side of the second support plate 202 away from the first support plate 201 towards the base body 101. This application provides the following three solutions, all of which can be used to restrict the movement of the side of the second support plate 202 away from the first support plate 201 towards the base body 101.

[0083] The first option, such as Figure 8 and Figure 9 As shown, Figure 8 This is a schematic diagram of the structure of a second support body and a fourth support body provided in an embodiment of this application. Figure 9This is a cross-sectional view of a second support body and a fourth support body provided in an embodiment of this application. The side of the second support body 2012 in the first support plate 201 facing the fourth support body 2022 in the second support plate 202 may have multiple first limiting members 2013. The side of the fourth support body 2022 in the second support plate 202 facing the second support body 2012 in the first support plate 201 may have multiple second limiting members 2023.

[0084] Each of the first limiting members 2013 corresponds one-to-one with a plurality of second limiting members 2023. When the hinge 000 is in the unfolded state, the first limiting member 2013 can abut against the corresponding second limiting member 2023, and the first limiting member 2013 can be closer to the support base 100 relative to the corresponding second limiting member 2023. Thus, when the hinge 000 is in the unfolded state, after the user applies pressure to the side of the second support plate 202 away from the first support plate 201, the second support body 2012 can restrict the movement of the side of the second support plate 202 away from the first support plate 201 toward the base body 101 through the abutment of the first limiting member 2013 on the second support body 2012 and the second limiting member 2023 on the fourth support body 2022.

[0085] The second option, such as Figure 8 and Figure 10 As shown, Figure 10 This is a cross-sectional view of another second support body and a fourth support body provided in an embodiment of this application. The side of the second support body 2012 in the first support plate 201 facing the fourth support body 2022 in the second support plate 202 may have multiple third limiting members 2014. The side of the fourth support body 2022 in the second support plate 202 facing the second support body 2012 may have multiple fourth limiting members 2024.

[0086] Among them, multiple third limiting members 2014 can correspond one-to-one with multiple fourth limiting members 2024. After the hinge 000 is in the unfolded state, the third limiting member 2014 can abut against the corresponding fourth limiting member 2024, and the fourth limiting member 2024 can be closer to the support base 100 relative to the third limiting member 2014. In this way, when the hinge 000 is in the unfolded state, after the user applies pressure to the side of the second support plate 202 away from the first support plate 201, the second support body 2012 can restrict the movement of the side of the second support plate 202 away from the first support plate 201 toward the base body 101 through the abutment of the third limiting member 2014 on the second support body 2012 and the fourth limiting member 2024 on the fourth support body 2022.

[0087] The third option, such as Figure 8As shown, the side of the second support body 2012 in the first support plate 201 facing the fourth support body 2022 in the second support plate 202 may have multiple first limiting members 2013 and multiple third limiting members 2014. Furthermore, in the first direction X, the multiple first limiting members 2013 and multiple third limiting members 2014 may be arranged alternately. The side of the fourth support body 2022 in the second support plate 202 facing the second support body 2022 in the first support plate 201 may have multiple second limiting members (2023) and multiple fourth limiting members (2024). Furthermore, in the first direction X, the multiple second limiting members 2013 and multiple fourth limiting members 2024 may be arranged alternately.

[0088] Among them, multiple first limiting members 2013 can correspond one-to-one with multiple second limiting members 2023, and multiple third limiting members 2014 can correspond one-to-one with multiple fourth limiting members 2024. After the hinge 000 is in the unfolded state, the first limiting member 2013 can abut against the corresponding second limiting member 2023, and the first limiting member 2013 can be closer to the support base 100 relative to the corresponding second limiting member 2023. At the same time, the third limiting member 2014 can abut against the corresponding fourth limiting member 2024, and the fourth limiting member 2024 can be closer to the support base 100 relative to the third limiting member 2014. Thus, when the hinge 000 is in the unfolded state, after the user applies pressure to the side of the second support plate 202 away from the first support plate 201, the second support body 2012 can restrict the movement of the side of the second support plate 202 away from the first support plate 201 toward the base body 101 by the contact between the first limiting member 2013 on the second support body 2012 and the second limiting member 2023 on the fourth support body 2022, and the contact between the third limiting member 2014 on the second support body 2012 and the fourth limiting member 2024 on the fourth support body 2022.

[0089] Optional, such as Figure 5 As shown, the rotating shaft component 203 in the flipping assembly 200 may further include: a drive rod 2033 and a second rotating part 2034. For example... Figure 11 As shown, Figure 11 This is a schematic diagram of a drive rod provided in an embodiment of this application. The drive rod 2033 in the rotating shaft component 203 can be rotatably connected to the base body 101, and the end of the drive rod 2033 facing away from the base body 101 can have a first sliding member 20331 and a second sliding member 20332. The first sliding member 20331 and the second sliding member 20332 in the drive rod 2033 can be arranged opposite to each other in the first direction X.

[0090] like Figure 5 and Figure 12 As shown, Figure 12This is a schematic diagram of the structure of a first rotating part provided in an embodiment of this application. The first rotating part 2032 in the rotating shaft component 203 may have a second arc-shaped groove H2 that is slidably connected to the first sliding member 20331 in the drive rod 2033. At least a portion of the first sliding member 20331 in the drive rod 2033 may be located within the second arc-shaped groove H2 of the first rotating part 2032. Thus, through the cooperation of the first sliding member 20331 and the second arc-shaped groove H2, the drive rod 2033 can be rotatably connected to the first rotating part 2032.

[0091] like Figure 5 and Figure 13 As shown, Figure 13 This is a schematic diagram of the structure of a second rotating part provided in an embodiment of this application. The second rotating part 2034 in the rotating shaft component 203 can be rotatably connected to the first rotating part 2032. Here, the second rotating part 2034 may have two third arc-shaped sliding grooves H4 arranged opposite each other in the first direction X, and the first rotating part 2032 may have two second arc-shaped sliding plates 20321 arranged opposite each other in the first direction X. The second arc-shaped sliding plates 20321 may be located at least within the corresponding third arc-shaped sliding grooves H4, so that the second rotating part 2034 can be rotatably connected to the first rotating part 2032 by sliding the second arc-shaped sliding plates 20321 within the third arc-shaped sliding grooves H4.

[0092] Furthermore, the second rotating part 2034 may have a first linear groove H3 that is slidably connected to the second sliding member 20332 in the drive rod 2033, and at least a portion of the second sliding member 20332 may be located within the first linear groove H3. Here, the second rotating part 2034 may have two first linear grooves H3 that are oppositely arranged in the first direction X, and the drive rod 2033 may have two second sliding members 20332 that are oppositely arranged in the first direction X. Thus, through the cooperation of the two second sliding members 20332 with the two first linear grooves H3 respectively, the drive rod 2033 can rotate with the rotation of the second rotating part 2034. The second rotating part 2034 may also be rotatably connected to the first support plate 201.

[0093] It should be noted that the second rotating part 2034 in the pivot component 203 can be fixedly connected to the housing of the foldable electronic device. During the process of applying force to the housing of the foldable electronic device to fold or unfold it, the second rotating part 2034, fixedly connected to the housing, can rotate relative to the support base 100. Furthermore, through the connection between the second rotating part 2034 and the first rotating part 2032 and the drive rod 2033 respectively, the second rotating part 2034 can drive the first rotating part 2032 and the drive rod 2033 to rotate relative to the support base 100.

[0094] It should also be noted that in the prior art, during the process of the second rotating part 2034 driving the first rotating part 2032 and the drive rod 2033 to rotate relative to the support base 100, in order to ensure the normal connection between the first rotating part 2032 and the drive rod 2033, it is generally necessary to set an additional rotating component between the drive rod 2033 and the first rotating part 2032 to achieve a rotational connection, so as to ensure that the first rotating part 2032 and the drive rod 2033 can be normally connected during the process of the first rotating part 2032 and the drive rod 2033 rotating relative to the support base 100 at the same time, thereby enabling the rotating shaft component 203 as a whole to rotate relative to the support base 100.

[0095] In this application, by simply sliding the first sliding member 20331 in the drive rod 2033 within the second arc-shaped groove H2 of the first rotating part 2032, the drive rod 2033 and the first rotating part 2032 can be properly connected while rotating simultaneously relative to the support base 100, thereby enabling the rotating shaft component 203 to move normally relative to the support base 100. Thus, compared to the prior art, the rotating shaft component 203 in this embodiment has fewer parts, higher motion accuracy, and consequently, higher overall motion accuracy of the hinge 000.

[0096] Optional, such as Figure 5 , Figure 11 and Figure 12 As shown, the end of the drive rod 2033 facing the base body 101 may also have a fifth limiting member 20333. The fifth limiting member 20333 in the drive rod 2033 may be located on the side of the drive rod 2033 where the first sliding member 20331 is distributed. The side of the first rotating part 2032 facing the base body 101 may also have a limiting groove B. The limiting groove B of the first rotating part 2032 may be located on the side of the first rotating part 2032 where the second arc-shaped groove H2 is distributed. Wherein, after the hinge is in the unfolded state, at least a portion of the fifth limiting member 20333 is located within the limiting groove B. Thus, after the hinge is in the unfolded state, the limiting groove B of the first rotating part 2032 limits the fifth limiting member 20333 of the drive rod 2033, preventing the hinge from folding in the opposite direction.

[0097] Optional, please refer to Figure 14 , Figure 14This is a schematic diagram of another hinge structure provided in another embodiment of this application. The hinge 000 may further include a torque component 300, which can be connected to two drive rods 2033 of two flipping components 200 disposed opposite each other in the second direction Y. The torque component 300 can generate resistance during the folding or unfolding of the hinge 000. Thus, during the unfolding or folding of the foldable electronic device, the user can obtain a certain tactile feedback through the torque component 300 in the hinge 000, thereby improving the user experience.

[0098] Optional, such as Figure 14 As shown, the torque assembly 300 in hinge 000 may include: a first support shaft 301, and a first torque member 302, a second torque member 303, a limiting plate 304, and an elastic element 305 sleeved on the first support shaft 301. The first support shaft 301 in the torque assembly 300 may be fixedly connected to the support base 100 and may be rotatably connected to one end of the drive rod 2033 facing the base body 101. Here, the drive rod 2033 may also be sleeved on the first support shaft 301. And the first torque member 302 and the second torque member 303 slide on the first support shaft 301, while the drive rod 2033 and the limiting plate 304 will not slide on the first support shaft 301.

[0099] The first torque member 302 and the second torque member 303 in the torque assembly 300 can be distributed on both sides of the drive rod 2033 in the first direction X, and both the first torque member 302 and the second torque member 303 can abut against the drive rod 2033. The limiting plate 304 in the torque assembly 300 can be distributed on the side of the second torque member 303 opposite to the first torque member 302 in the first direction X. The elastic element 305 in the torque assembly 300 can be distributed between the second torque member 303 and the limiting plate 304.

[0100] It should be noted that, through the contact between the first torque member 302 and the second torque member 303 and the drive rod 2033, during the rotation of the drive rod 2033 relative to the first support shaft 301, the drive rod 2033 can drive the first torque member 302 and the second torque member 303 to continuously slide back and forth on the first support shaft 301, thereby causing the elastic element 305 to continuously compress and recover. Thus, the torque assembly 300 can be used to generate resistance during the folding or unfolding of the hinge 000.

[0101] Optionally, the side of the first torque member 302 facing away from the end cover 102 in the torque assembly 300 may have a second arcuate surface A2, the side of the second torque member 303 facing away from the end cover 102 may have a third arcuate surface A3, and the side of the limiting plate 304 facing away from the end cover 102 may have a fourth arcuate surface A4. During the switching between the unfolded and folded states of the hinge 000, the side of the second support plate 204 facing away from the first support plate 201 may also contact at least one of the second arcuate surface A2, the third arcuate surface A3, and the fourth arcuate surface A4.

[0102] Thus, during the transition of hinge 000 from the unfolded state to the folded state, under the combined action of the first support plate 201 and the first arc-shaped surface A1, as well as at least one of the second arc-shaped surface A2, the third arc-shaped surface A3, and the fourth arc-shaped surface A4, the distance between the two second support plates 202 of the two flip-up components 200 arranged opposite each other on both sides of the support base 100 can gradually increase, so that the second support plates 202 gradually no longer cover the support base 100, thereby gradually increasing the space between the support base 100 and the folding display screen. During the transition of hinge 000 from the folded state to the unfolded state, under the combined action of the first support plate 201 and the first arc-shaped surface A1, as well as at least one of the second arc-shaped surface A2, the third arc-shaped surface A3, and the fourth arc-shaped surface A4, the distance between the two second support plates 202 of the two flip-up components 200 arranged opposite each other on both sides of the support base 100 can gradually decrease, and the second support plates 202 can gradually cover the support base 100.

[0103] Optional, such as Figure 14 As shown, the hinge 000 may further include at least one synchronization component 400. The at least one synchronization component 400 in the hinge 000 can be synchronously connected to two drive rods 2033 of two flipping components 200 respectively disposed opposite to each other on both sides of the support base 100. It should be noted that synchronous connection here means that the movement of one component can drive the synchronous movement of another component. Therefore, during the folding or unfolding of the hinge 000, when the flipping component 200 on one side of the support base 100 rotates, the flipping component 200 on the other side of the support base 100 can rotate synchronously through the synchronization component 400. Thus, synchronous opposite rotation and synchronous opposite rotation between the flipping components 200 can be achieved through the synchronization component 400.

[0104] Optional, such as Figure 14As shown, each of the drive rods 2033 facing the support base 100 has multiple external teeth 20334. The synchronization assembly 400 may have gears 401 that mesh with the multiple external teeth 20334 in the drive rods 203, and the synchronization assembly 400 may include two gears 401, which can respectively mesh with the external teeth 20334 of the drive rods 2033. In this way, when the drive rod 2033 on one side of the support base 100 rotates, the drive rod 2033 on the other side of the support base 100 can rotate synchronously.

[0105] In summary, this application provides a hinge comprising a support base and at least two flipping components. During the hinge's transition from an unfolded state to a folded state, the distance between the two second support plates of the two flipping components positioned opposite each other on both sides of the support base gradually increases, reaching its maximum distance when the hinge is in the folded state. This results in a larger space between the support base and the foldable display screen when the hinge is in the folded state. Therefore, when a foldable electronic device equipped with this hinge is in the folded state, if the device falls and the hinge-equipped side contacts the ground, the probability of the support base, which moves towards the foldable display screen, being subjected to impact force and causing pressure on the display screen is low, thus reducing the probability of damage to the display screen and improving the reliability of the foldable electronic device equipped with this hinge.

[0106] This application also provides an electronic device that may include the hinge described in the above embodiments. The electronic device may further include a foldable display screen and at least two housings. The at least two housings in the electronic device can be connected by the hinge, and the foldable display screen can be disposed on the at least two housings. Thus, the housings can be unfolded or folded via the hinge, thereby allowing the housings to drive the foldable display screen to unfold or fold. For example, the housing may be fixedly connected to a first rotating part of the hinge.

[0107] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0108] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
