Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a rotating mechanism, a support device, and a foldable screen terminal. Background Technology

[0002] With the advancement of technology, the era of large-screen smart terminals has arrived. In order to solve the problems of traditional tablet computers being bulky and inconvenient to carry, and the small screens of candybar phones, foldable screen terminals have emerged.

[0003] When the device is unfolded, the foldable screen displays the large screen. When the device is folded, the foldable screen is hidden, and the display is shown on the outer screen. However, when the device is folded, the hinge cover of the device's rotating mechanism is exposed. When the hinge cover is impacted, it will deform, causing problems with the top screen and potentially leading to screen failure. Summary of the Invention

[0004] This application provides a rotating mechanism, a support device, and a foldable screen terminal to solve the problem that when the hinge cover is deformed by impact during the folding of the foldable screen terminal, the top screen will fail.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, a rotating mechanism is provided, comprising a shaft cover, a first door panel, a second door panel, a plurality of first swing arms, and a plurality of second swing arms. The width direction of the shaft cover is a first direction, and the length direction of the shaft cover is a second direction. The first door panel is rotatable relative to the shaft cover. The second door panel is rotatable relative to the shaft cover, and the first door panel and the second door panel are distributed along the first direction. The plurality of first swing arms are rotatably disposed on the shaft cover and distributed along the second direction; the first swing arms are used to drive the first door panel to rotate. The plurality of second swing arms are rotatably disposed on the shaft cover and distributed along the second direction; the second swing arms are used to drive the second door panel to rotate; and the rotation direction of the second swing arms is opposite to that of the first swing arms. Each first swing arm includes a rotating arm and a supporting rib; the rotating arm is rotatably disposed on the shaft cover; the supporting rib is fixedly connected to the rotating arm and fixedly connected to the first door panel; adjacent supporting ribs are interlocked by a plug-in structure.

[0007] The rotating mechanism provided in the first aspect of this application drives the first and second door panels to rotate between a folded position and an unfolded position by rotating the first and second swing arms in opposite directions. Since the support ribs of adjacent first swing arms are interlocked via a plug-in structure, there is no gap between adjacent support ribs. In this way, the support ribs of the multiple first swing arms can provide support at any position along the length of the cover. When the cover is impacted at any position along its length, the support ribs can provide effective support to prevent the cover from hitting the screen, thus ensuring the screen's integrity.

[0008] Furthermore, the multiple supporting ribs are independent components, and adjacent supporting ribs are connected to each other through a plug-in structure. On the one hand, this can form a continuous supporting structure along the length of the shaft cover; on the other hand, it helps to improve the overall supporting strength and avoid the situation where the supporting ribs cannot form effective support due to insufficient supporting strength.

[0009] In some embodiments of the first aspect of this application, along the second direction, partial areas of the ends of two adjacent support ribs overlap each other, and a plug-in structure is disposed between the surfaces of the two adjacent support ribs that are opposite each other and parallel to the second direction. In this way, the plug-in structure between the overlapping areas of two adjacent support ribs increases the connection area between them, thereby improving their supporting strength.

[0010] In some embodiments of the first aspect of this application, each of the ends of two adjacent support ribs is provided with a stepped structure, the stepped surfaces of the two stepped structures are in contact with each other, and a plug-in structure is provided between the two stepped surfaces parallel to the second direction on the two stepped structures. By providing a stepped structure at the ends of the two support ribs, the connection area between them can be increased, and the support strength can be improved without increasing the dimension in the thickness direction of the support ribs, thereby not increasing the thickness of the end, which is beneficial to the overall thinness of the structure.

[0011] In some embodiments of the first aspect of this application, two adjacent support ribs include a first support rib and a second support rib. The insertion structure includes a protrusion and a groove. The protrusion is disposed on the surface of the first support rib facing the second support rib and parallel to a second direction, and the groove is formed on the surface of the second support rib facing the first support rib and parallel to the second direction. The protrusion is inserted into the groove. In this way, by inserting the protrusion into the groove, the contact area between the first support rib and the second support rib is increased, thereby improving the support strength between them.

[0012] In some embodiments of the first aspect of this application, the groove extends along a second direction and penetrates the end face of the second support rib toward the first support rib, while the protrusion is inserted into the groove from the end face of the second support rib. In this way, the first and second support ribs can be interlocked along the second direction, which facilitates their installation and positioning, thereby reducing installation difficulty.

[0013] In some embodiments of the first aspect of this application, in a cross-section perpendicular to the second direction, the groove opening width is greater than the groove bottom width, and the cross-sectional shape of the protrusion is adapted to the cross-sectional shape of the groove. With this structure, the first and second support ribs can be interlocked and positioned along a direction perpendicular to the second direction to prevent them from separating along that direction.

[0014] In some embodiments of the first aspect of this application, the cross-sectional shape of the protrusion and the groove along the direction perpendicular to the second direction is trapezoidal. That is, the opening of the groove cross-section is the short side of the trapezoid, and the bottom of the groove is not the long side of the trapezoid, thereby preventing the protrusion from separating from the groove along the direction perpendicular to the second direction from the opening of the groove, that is, the trapezoidal structure forms a limit.

[0015] In some embodiments of the first aspect of this application, the protrusion includes a first protrusion and a second protrusion. The first protrusion is disposed on a first support rib, and the second protrusion is disposed at the end of the first protrusion away from the first support rib. In a cross-section perpendicular to the second direction, the width of the second protrusion is greater than the width of the first protrusion. That is, the second protrusion abuts against the groove to form a limit in the direction perpendicular to the second direction, thereby preventing the protrusion from separating from the groove opening.

[0016] In some embodiments of the first aspect of this application, two adjacent support ribs include a first support rib and a second support rib. The insertion structure includes a limiting hole and a limiting post. The limiting hole is formed on the surface of the first support rib facing the second support rib and parallel to a second direction. The limiting post is disposed on the surface of the second support rib facing the first support rib and parallel to the second direction. The limiting post is inserted into the limiting hole. In this way, by inserting the limiting post into the limiting hole, the contact area between the first support rib and the second support rib is increased, thereby improving the support strength between them.

[0017] In some embodiments of the first aspect of this application, multiple limiting posts and multiple limiting holes are provided, and the multiple limiting posts and multiple limiting holes are distributed along the second direction. The one-to-one insertion of multiple limiting posts and multiple limiting holes is beneficial for further improving the support strength.

[0018] In some embodiments of the first aspect of this application, the cross-section of the limiting post and the limiting hole is circular, elliptical, or polygonal.

[0019] In some embodiments of the first aspect of this application, the plug-in structure includes a connecting plate and a slot, with the connecting plate disposed between two adjacent support ribs. The slot is formed on the end face of the support rib facing the connecting plate, and the end of the connecting plate is inserted into the slot; alternatively, the slot is formed on the end face of the connecting plate facing the support rib, and the end of the support rib is inserted into the slot. In this way, two adjacent support ribs are connected by the connecting plate, i.e., the connecting plate forms support at the interval between two adjacent support ribs, thereby avoiding the top screen problem.

[0020] In some embodiments of the first aspect of this application, the slot extends in a direction perpendicular to the second direction and penetrates the sidewall of the support rib or connecting plate. This allows the support rib and connecting plate to interlock along the extension direction of the slot, improving positioning accuracy and reducing installation difficulty.

[0021] In some embodiments of the first aspect of this application, in a cross-section perpendicular to the extension direction of the slot, the bottom width of the slot is greater than the opening width of the slot, and the cross-sectional shape of the end of the support rib or connecting plate is adapted to the cross-sectional shape of the slot. Under this structure, a limiting device can be formed between the connecting plate and the support rib to prevent the connecting plate and the support rib from separating from each other along the second direction.

[0022] In some embodiments of the first aspect of this application, the second swing arm has the same structure as the first swing arm, and the support ribs of adjacent second swing arms are all interlocked by a plug-in structure. In this way, when the terminal is in a folded state, both the first and second swing arms can provide effective support, thereby helping to balance the overall force and further improving the overall support strength.

[0023] Secondly, a rotating mechanism is provided, comprising a shaft cover, a first door panel, a second door panel, a plurality of first swing arms, and a plurality of second swing arms. The width direction of the shaft cover is a first direction, and the length direction of the shaft cover is a second direction. The first door panel is rotatable relative to the shaft cover. The second door panel is rotatable relative to the shaft cover, and the first door panel and the second door panel are distributed along the first direction. The plurality of first swing arms are rotatably mounted on the shaft cover and distributed along the second direction, and the first swing arms are used to drive the first door panel to rotate. The plurality of second swing arms are rotatably mounted on the shaft cover and distributed along the second direction, and the second swing arms are used to drive the second door panel to rotate; and the rotation direction of the second swing arms is opposite to that of the first swing arms. Each first swing arm includes a rotating arm, a support rib, and a fastener, and the rotating arm is rotatably mounted on the shaft cover. The support rib is fixedly connected to the rotating arm and fixedly connected to the first door panel, with adjacent support ribs abutting against each other. The fastener is used to connect adjacent support ribs.

[0024] The rotating mechanism provided in the second aspect of this application abuts two adjacent support ribs together, thereby preventing gaps between them. Furthermore, the adjacent support ribs are locked together by fasteners, which helps to increase the support strength at the point where they abut. In this way, when the cover is impacted, the support ribs can provide support, preventing the cover from hitting the screen and thus protecting the screen's integrity.

[0025] In some embodiments of the second aspect of this application, along the second direction, the adjacent ends of two adjacent support ribs partially overlap each other, and fasteners sequentially penetrate the overlapping portions of the two adjacent support ribs and lock the two support ribs. In this way, the ends of the two adjacent support ribs have partially overlapping areas, which helps to increase the contact area between the two adjacent support ribs, and the locking mechanism further enhances the connection strength between them, thereby increasing the support strength of the support ribs.

[0026] In some embodiments of the second aspect of this application, two adjacent support ribs include a first support rib and a second support rib. A connecting block is provided on the end face of the first support rib facing the second support rib, and a receiving groove is formed on the end face of the second support rib facing the first support rib. The connecting block is inserted into the receiving groove, and fasteners sequentially penetrate the areas on the connecting block and the second support rib corresponding to the receiving groove, thereby locking the connecting block and the second support rib on the first support rib. In this way, by setting the connecting block and the receiving groove to be interlocked, the dimensions of multiple support ribs along the thickness direction can be increased while locking the first support rib and the support rib, which is beneficial to the overall thinness of the terminal.

[0027] In some embodiments of the second aspect of this application, threaded holes are provided in the areas where receiving grooves are formed on the connecting block and the second support rib. The fastener includes a screw, which is inserted into and engages with the threaded hole. This allows the first and second support ribs to be locked together by the screw, achieving a fixed connection between them and improving the connection strength.

[0028] In some embodiments of the second aspect of this application, the second swing arm has the same structure as the first swing arm, and the support ribs of two adjacent second swing arms abut against each other and are locked together by a locking member. In this way, when the terminal is in a folded state, both the first and second swing arms can provide effective support, thereby helping to balance the overall force and further improving the overall support strength.

[0029] Thirdly, a support device is provided, which includes a first housing, a second housing, and a rotating mechanism as described in any of the above technical solutions. The rotating mechanism is located between the first housing and the second housing, and the first door plate of the rotating mechanism is connected to the first housing, and the second door plate of the rotating mechanism is connected to the second housing.

[0030] The support device provided in the third aspect of this application includes the rotating mechanism provided in any of the above technical solutions. Therefore, it can solve the same technical problem and achieve the same technical effect.

[0031] Fourthly, a foldable screen terminal is provided, comprising a foldable screen and a supporting device. The foldable screen includes a first part, a second part, and a third part, with the third part located between the first and second parts. The supporting device is as described in the above technical solution, with the first part fixed to a first housing, the second part fixed to a second housing, and the third part supported on a rotating mechanism.

[0032] The foldable screen terminal provided in the fourth aspect of this application includes the support device provided by the above technical solution. Therefore, it can solve the same technical problem and achieve the same technical effect. Attached Figure Description

Detailed Implementation

[0054] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0055] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0056] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0057] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0058] This application provides a foldable screen terminal, which can be a type of electronic device with a foldable screen. This embodiment uses a foldable screen terminal as an example. Figure 1 The mobile phone shown is used for illustration. For details, please refer to [link / reference]. Figure 1 , Figure 1 This is a structural diagram of a foldable screen terminal 01 provided in some embodiments of this application. The foldable screen terminal 01 includes a foldable screen 10 and a support device 20.

[0059] For the sake of clarity in the following embodiments, an XYZ coordinate system is established, defining the width direction of the foldable screen terminal 01 as the X-axis, the length direction of the foldable screen terminal 01 as the Y-axis, and the thickness direction of the foldable screen terminal 01 as the Z-axis. It is understood that the coordinate system of this foldable screen terminal 01 can be flexibly set according to actual needs. This application only provides an example and should not be considered as a special limitation imposed on this application.

[0060] The foldable screen 10 is used to display images, videos, etc. The foldable screen 10 includes a first portion 110, a second portion 120, and a third portion 130, with the third portion 130 disposed between the first portion 110 and the second portion 120. When the foldable screen 10 is folded, the third portion 130 is bent, and the first portion 110 and the second portion 120 are positioned opposite each other. At least the third portion 130 of the foldable screen 10 is made of a flexible material. The first portion 110 and the second portion 120 can be made of flexible materials, rigid materials, or a combination of both. This application does not specifically limit this.

[0061] Among them, the aforementioned foldable screen 10 can be an organic light-emitting diode (OLED) screen, a micro organic light-emitting diode (micro organic light-emitting diode) screen, a quantum dot light-emitting diode (QLED) screen, a liquid crystal display (LCD) screen, etc.

[0062] Please see Figure 2 and Figure 3 , Figure 2 for Figure 1 The provided structural diagram of the support device 20 for the foldable screen terminal 01. Figure 3 for Figure 1 The provided front view of the foldable screen terminal 01. The foldable screen 10 is supported on a support device 20. The support device 20 includes a first housing 201, a second housing 202, and a rotating mechanism 203, which is connected between the first housing 201 and the second housing 202. A first portion 110 of the foldable screen 10 is supported and attached to the first housing 201. A second portion 120 of the foldable screen 10 is supported and attached to the second housing 202. A third portion 130 of the foldable screen 10 is supported and attached to the rotating mechanism 203. The first housing 201 and the second housing 202 are rotatably connected by the rotating mechanism 203, thereby allowing the foldable screen terminal 01 to rotate between an unfolded position and a folded position.

[0063] Please continue reading. Figures 1-3 , Figures 1-3 The diagram shows the structure of the foldable screen terminal 01 or the support device 20 in the unfolded position. When the foldable screen terminal 01 is in the unfolded position, the first housing 201, the second housing 202, and the rotating mechanism 203 of the support device 20 are all in the same plane facing the foldable screen 10, so that the foldable screen 10 is fully opened and its flatness is guaranteed. In this state, a large-screen display can be achieved, providing users with a better user experience.

[0064] Please see Figure 4 , Figure 4 for Figure 1 The provided foldable screen terminal 01 is shown in its folded position from the front. When the foldable screen terminal 01 is in its folded position, the first part 110 is opposite to the second part 120, the third part 130 is in a bent state, the support device 20 protects the foldable screen 10 from the outside, and the foldable screen 10 is not visible to the user, so as to prevent the foldable screen 10 from being scratched or damaged, thereby effectively protecting the foldable screen 10.

[0065] Please see Figure 5 , Figure 5 This is a front view of the rotating mechanism 203 provided in an embodiment of this application. The rotating mechanism 203 may include a shaft cover 200, a first door panel 300, a second door panel, a first swing arm 400, and a second swing arm. Since the first door panel 300, the first swing arm 400, the second door panel, and the second swing arm have the same structure, therefore... Figure 5 The accompanying drawings below only show the structures of the first door panel 300 and the first swing arm 400. Furthermore, the aforementioned shaft cover 200 is an external component; when the foldable screen terminal 01 is in the folded position, the shaft cover 200 is exposed to prevent other components from being exposed, thus contributing to the overall aesthetics.

[0066] The first door panel 300 and the second door panel are disposed between the first housing 201 and the second housing 202, that is, the first door panel 300 and the second door panel are distributed along the X direction, and the first door panel 300 is fixedly connected to the first housing 201, and the second door is fixedly connected to the second housing 202, so as to realize that the first door panel 300 and the second door panel drive the first housing 201 and the second housing 202 to rotate between the folded position and the unfolded position.

[0067] The first swing arm 400 and the second swing arm are both disposed between the first door panel 300 and the second door panel, that is, the first swing arm 400 and the second swing arm are distributed along the X direction, and the first swing arm 400 is fixedly connected to the first door panel 300, and the second swing arm is fixedly connected to the second door panel. In addition, the first swing arm 400 and the second swing arm are both rotatably connected to the shaft cover 200, and the rotation directions of the first swing arm 400 and the second swing arm are opposite, thereby realizing the rotation of the foldable screen terminal 01 between the folded position and the unfolded position.

[0068] Please continue reading for more details. Figure 5 The aforementioned first swing arm 400 and second swing arm are provided in multiples along the length direction (i.e., the Y-axis direction) of the shaft cover 200 and are spaced apart to form multi-point support, which is beneficial to improving the overall structural support strength. Specifically, the first swing arm 400 may include a rotating arm 410 and a support rib 420. The rotating arm 410 and the support rib 420 are fixedly connected. The end of the rotating arm 410 away from the support rib 420 is rotatably mounted on the shaft cover 200 to achieve a rotatable connection between the first swing arm 400 and the shaft cover 200. The support rib 420 is fixedly connected to the first door panel 300. For example, the support rib 420 and the first door panel 300 can be fixedly connected by bolts, pins, etc. In addition, the specific structure and connection method of the second swing arm are the same as those of the first swing arm 400, and will not be described again in this application.

[0069] In this way, through multiple first swing arms 400 and multiple second swing arms, the first door panel 300 and the second door panel can be driven to rotate in opposite directions, thereby driving the first housing 201 and the second housing 202 to rotate in opposite directions, so as to realize the rotation of the foldable screen terminal 01 between the folded position and the unfolded position.

[0070] However, since the hinge cover 200 is exposed when the foldable screen terminal 01 is in the folded position, it will deform and indent when subjected to external impact. At this time, the impact occurs in the space between two adjacent first swing arms 400 and the second swing arm (i.e., the space between two adjacent support ribs 420, such as...). Figure 5 If the impact force is at the location indicated by the dashed box, it may be transmitted to the folding screen 10 through the shaft cover 200, causing a problem with the top screen, which may lead to the failure of the folding screen 10.

[0071] Therefore, to avoid the aforementioned top screen issues, please refer to [link / reference needed]. Figure 6 and Figure 7 , Figure 6 A front view of the rotating mechanism 203 provided for related technologies. Figure 7 for Figure 6 The provided rotating mechanism 203 includes a structural diagram of the support rib 420 and the rotating arm 410. Related technologies configure multiple support ribs 420 distributed along the Y-axis as an integral structure, meaning only one support rib 420 is provided along the Y-axis, and the length of this support rib 420 is adapted to the length of the first door panel 300, i.e., the length of the support rib 420 is equal to or slightly less than the length of the first door panel 300. Multiple rotating arms 410 are provided on this support rib 420. In this way, since the support ribs 420 form a continuous structure, there is no gap along the Y-axis, effectively preventing deformation of the cover 200 due to impact, thus avoiding top screen problems.

[0072] It should be noted that, under this structure, the structures of the multiple first swing arms 400 and the multiple second swing arms can be identical, that is, the support ribs 420 of the multiple first swing arms 400 and the multiple second swing arms can both be set as an integral structure. Alternatively, the structures of the multiple first swing arms 400 and the multiple second swing arms can also be different, that is, the support ribs 420 of the multiple first swing arms 400 can be set as an integral structure, while the multiple second swing arms are still distributed at intervals along the Y-axis direction. Therefore, this application does not impose any special limitations on this.

[0073] However, excessive length of the support rib 420 reduces its supporting strength. This reduced strength diminishes its effectiveness in blocking impacts; when impacted by the shaft cover 200, the support rib 420 is prone to deformation and cannot effectively block the impact. Furthermore, during manufacturing, a longer support rib 420 will also have reduced straightness, affecting its support for the folding screen 10 and reducing its flatness. Therefore, the feasibility of integrating multiple support ribs 420 into a single structure is low.

[0074] To address the aforementioned problems, this application provides another rotating mechanism 203, which may include the aforementioned shaft cover 200, first door panel 300, second door panel, multiple first swing arms 400, and multiple second swing arms. Each first swing arm 400 may include the aforementioned rotating arm 410 and support rib 420. Furthermore, the support ribs 420 of adjacent first swing arms 400 can be interconnected via a connecting structure to avoid gaps between adjacent support ribs 420.

[0075] For example, please see Figure 8 and Figure 9 , Figure 8 This is a structural diagram of two adjacent support ribs 420 provided in an embodiment of this application. Figure 9 for Figure 8 The provided enlarged view shows a partial structure of the support rib 420. The support ribs 420 of two adjacent first swing arms 400 can be interlocked via the insertion structure 500, thus forming a continuous support structure with no gaps along the Y direction. Therefore, the support ribs 420 of the multiple first swing arms 400 can provide support at any position along the length direction (Y direction) of the cover 200. When any position on the cover 200 along the length direction (Y direction) is impacted, the support ribs 420 can provide effective support to prevent deformation of the cover 200 and damage to the top screen, thereby ensuring the integrity of the folding screen 10.

[0076] Furthermore, multiple support ribs 420 are interconnected via interlocking structures 500, meaning each support rib 420 is an independent component whose length can be determined according to actual needs. The length of each support rib 420 can be determined based on its own strength, without needing to be excessively long, which would reduce the support strength. Therefore, effective support can be formed.

[0077] In some embodiments, along the Y direction, the ends of two adjacent support ribs 420 may partially overlap. The aforementioned insertion structure 500 is disposed between the surfaces of the two adjacent support ribs 420 that are opposite each other and parallel to the Y direction. That is, the insertion structure 500 is disposed between the overlapping areas of the two adjacent support ribs 420. By partially overlapping the two adjacent support ribs 420, the contact area between the two support ribs 420 is increased, thereby improving the connection strength of the interlocking area between them, and thus improving the support strength of the adjacent areas.

[0078] In addition, to avoid increasing the thickness dimension (i.e., the Z-direction dimension) of the overlapping area of ​​two adjacent support ribs 420 along the Y direction, the two adjacent support ribs 420 can be respectively provided on the step structure, and the step surfaces on the step structure of the two adjacent support ribs 420 fit together. The above-mentioned plug-in structure 500 is provided between the two step surfaces parallel to the Y direction on the two step structures.

[0079] For example, please continue reading Figure 8 and Figure 9 Two adjacent support ribs 420 are designated as first support rib 421 and second support rib 422, respectively. The overlapping area of ​​the first support rib 421 and the second support rib 422 is designated as first region 421a, and the overlapping area of ​​the second support rib 422 and the first support rib 421 is designated as second region 422a. A first step structure is formed on the surface of the first region 421a facing the shaft cover 200. In the first step structure, the step surface parallel to the Y direction is designated as first step surface 4211a, and the step surface perpendicular to the Y direction is designated as first step surface 4211b. A second step structure is formed on the surface of the second region 422a away from the shaft cover 200. In the second step structure, the step surface parallel to the Y direction is designated as second step surface 4221a, and the step surface perpendicular to the Y direction is designated as second step surface 4221b.

[0080] When the first region 421a overlaps with the second region 422a, that is, the first region 421a is located on the side of the second region 422a away from the shaft cover 200, and the first step surface 4211a and the second step surface 4221a are in contact with each other, the aforementioned insertion structure 500 is disposed between the first step surface 4211a and the second step surface 4221a. Furthermore, along the Y direction, the first step surface 4211b abuts against the end face of the second support rib 422, and the second step surface 4221b abuts against the end face of the first support rib 421.

[0081] Therefore, it can be seen that by cooperating with the first step structure and the second step structure, the dimensions of the first support rib 421 and the second support rib 422 along the Z-axis will not be increased, that is, their thickness will not be increased, thus the thickness of the terminal will not be increased, which is conducive to the thinning of the terminal.

[0082] Furthermore, since the first stepped surface 4211b abuts against the end face of the second supporting rib 422, that is, along the Z direction, the gap between the first stepped surface 4211b and the end face of the second supporting rib 422 is covered by the first stepped surface 4211a, thereby compensating for the support strength at the gap between them. Similarly, the second stepped surface 4221b abuts against the end face of the first supporting rib 421, that is, along the Z direction, the gap between the second stepped surface 4221b and the end face of the first supporting rib 421 is covered by the second stepped surface 4221a, thereby compensating for the support strength at the gap between them. This enhances the support strength at the connection between the first supporting rib 421 and the second supporting rib 422.

[0083] It should be noted that the first step surface 4211a and the second step surface 4221a are parallel to the Y direction. That is, the first step surface 4211a and the second step surface 4221a can be surfaces parallel to the XY plane, surfaces parallel to the YZ plane, or inclined planes that form acute or obtuse angles with the XY plane and the YZ plane. This application does not make any special limitations on this.

[0084] Based on this, the specific structure of the above-mentioned plug-in structure 500 will be described in detail below. Among them, the two adjacent support ribs 420 include the first support rib 421 and the second support rib 422, and the first support rib 421 is provided with the first step structure, and the second support rib 422 is provided with the second step structure.

[0085] In one possible example, please continue reading Figure 8 and Figure 9 The aforementioned insertion structure 500 may include a protrusion 510 and a groove 520. The protrusion 510 is disposed on the first stepped surface 4211a, and the groove 520 is disposed on the second stepped surface 4221a. The protrusion 510 is inserted into the groove 520. By inserting the protrusion 510 into the groove 520, the contact area between the first support rib 421 and the second support rib 422 can be increased, thereby improving the support strength.

[0086] To further increase the contact area between the protrusion 510 and the groove 520, the groove 520 and the protrusion 510 can extend along the Y direction, and the groove 520 penetrates the end face of the second support rib 422 facing the first step surface 4211b, so that the protrusion 510 can be inserted into the groove 520 along the Y direction and from the end face of the second support rib 422, thereby further increasing the contact area between the first support rib 421 and the second support rib 422, thereby further improving the support strength of the connection area between the two.

[0087] To prevent the first support rib 421 and the second support rib 422 from separating in a direction perpendicular to the Y direction, i.e., to prevent the first step surface 4211a and the second step surface 4221a from separating. Please refer to [link / reference needed]. Figure 10 , Figure 10 for Figure 9 In the cross-sectional view of the provided plug-in structure 500, along the section perpendicular to the Y direction, the groove opening width D1 of the groove 520 is smaller than the groove bottom width D2, and the cross-sectional shape of the protrusion 510 is adapted to the groove 520. This prevents the protrusion 510 from dislodging from the groove 520 along the direction perpendicular to the Y direction, thus allowing the first step surface 4211a and the second step surface 4221a to separate in a direction away from each other.

[0088] It should be noted that the cross-sectional shape of the protrusion 510 being compatible with the cross-sectional shape of the groove 520 means that, along the cross-section perpendicular to the Y direction, the shape of the protrusion 510 is the same as the shape of the groove 520, and the size of the protrusion 510 is slightly smaller than the size of the groove 520, so that the protrusion 510 can be inserted into the groove 520.

[0089] For example, please continue reading Figure 10 In a cross-section perpendicular to the Y direction (i.e., parallel to the XZ plane), the cross-sectional shape of the protrusion 510 and the groove 520 can be a trapezoidal structure. Specifically, the opening of the groove 520 is the shorter side of the trapezoid, and the bottom of the groove 520 is the longer side. Correspondingly, the edge of the protrusion 510 near the first step surface 4211a is the shorter side of the trapezoid, and the edge of the protrusion 510 away from the first step surface 4211a is the longer side. This prevents the protrusion 510 from detaching from the groove 520 at its opening, thus creating a limiting effect between the first step surface 4211a and the second step surface 4221a, preventing them from separating. It is understood that the trapezoidal structure can be a right trapezoid, an isosceles trapezoid, or an isosceles trapezoid, etc. This application does not impose any special limitations on this.

[0090] Alternatively, please see Figure 11 , Figure 11This is a cross-sectional view of another protrusion 510 and groove 520 provided in an embodiment of this application. Along a cross-section perpendicular to the Y direction (i.e., a cross-section parallel to the XZ plane), the cross-sectional shape of the protrusion 510 and groove 520 can also be an approximately "T"-shaped structure. Specifically, the protrusion 510 may include a first protrusion 511 and a second protrusion 512. The first protrusion 511 is disposed on the aforementioned first step surface 4211a, and the second protrusion 512 is fixed to the side of the first protrusion 511 away from the first step surface 4211a. The width D3 of the first protrusion 511 is smaller than the width D4 of the second protrusion 512. That is, the first protrusion 511 and the second protrusion 512 form an approximately "T"-shaped structure, and the cross-section of the groove 520 is adapted to the protrusion 510. Therefore, when the protrusion 510 is inserted into the groove 520, the second protrusion 512 abuts against the inner wall of the groove 520, thereby preventing the first step surface 4211a and the second step surface 4221a from moving away from each other.

[0091] Therefore, it can be seen that the limiting effect formed between the first step surface 4211a and the second step surface 4221b can further enhance the support strength of the connection area between the first support rib 421 and the second support rib 422. Specifically, when Figure 5 as well as Figure 6 The shown shaft cover 200 is subjected to an external impact, and the impact force is located at... Figure 8 When the impact force is applied to the overlapping area between the first support rib 421 and the second support rib 422, it is first transmitted through the shaft cover 200 to the second region 422a of the second support rib 422. This external force causes deformation of the second region 422a of the second support rib 422. When the external force is transmitted to the first region 421a of the first support rib 421, the first region 421a of the first support rib 421 moves away from the second region 422a of the second support rib 422. At this time, the second region 422a of the second support rib 422 fully bears the external force.

[0092] When a limiting force is formed between the first step surface 4211a and the second step surface 4221a, the external force is transmitted to the first region 421a of the first support rib 421. Due to the limiting effect of the protrusion 510 and the groove 520, the first region 421a of the first support rib 421 cannot move away from the second region 422a of the second support rib 422. At this time, the first region 421a of the first support rib 421 and the second region 422a of the second support rib 422 jointly bear the external force. Therefore, the possibility of the external force being transmitted to the folding screen 10 can be reduced, that is, the support strength of the overlapping area between the first support rib 421 and the second support rib 422 is improved.

[0093] The above explanation assumes that the first step surface 5211a and the second step surface 5221a are parallel to the XY plane. For other details, please refer to [link to relevant documentation]. Figure 12 , Figure 12 This is a cross-sectional view of another type of protrusion 510 and groove 520 provided in an embodiment of this application. The first step surface 5211a and the second step surface 5221a can also be parallel to the YZ plane, i.e., perpendicular to the X direction. In this case, the orientation of the protrusion 510 and groove 520 is as follows... Figure 12 As shown, since its function is the same as the structure described above, it will not be described again.

[0094] It is understood that the orientation of the first step surface 5211a and the second step surface 5221a described above is merely an example and does not constitute a special limitation. The specific orientation of the first step surface 5211a and the second step surface 5221a can be flexibly changed according to actual needs.

[0095] In another possible example, please see Figure 13 and Figure 14 , Figure 13 This is a structural diagram of another plug-in structure 500 provided in an embodiment of this application. Figure 14 for Figure 13 A front view of the provided plug-in structure 500. The plug-in structure 500 may include a limiting post 530 and a limiting hole 540. The limiting hole 540 is formed on the first stepped surface 4211a of the first support rib 421, and the limiting post 530 is disposed on the second stepped surface 4221a of the second support rib 422. The axes of the limiting hole 540 and the limiting post 530 are perpendicular to the first stepped surface 4211a, and the limiting post 530 is inserted into the limiting hole 540. That is, the limiting post 530 and the limiting hole 540 increase the connection area between the first support rib 421 and the second support rib 422, thereby improving the support strength.

[0096] Furthermore, the number of the aforementioned limiting post 530 and limiting hole 540 can be one or more. For example, when only one limiting post 530 and one limiting hole 540 are provided, the cross-sectional area of ​​the limiting post 530 and the limiting hole 540 can be set to a larger size within the first step surface 4211a. Alternatively, when multiple limiting posts 530 and multiple limiting holes 540 are provided, the multiple limiting posts 530 and multiple limiting holes 540 are arranged in a one-to-one correspondence and distributed along the Y-axis direction.

[0097] Understandably, please refer to Figure 15 , Figure 15 for Figure 13Another schematic diagram of the provided plug-in structure 500. The cross-sections of the aforementioned limiting post 530 and limiting hole 540 can be circular, elliptical, rectangular, square, rhomboid, regular polygonal, or irregular shapes, etc. This application does not impose any special limitations on them.

[0098] In yet another possible example, please refer to Figure 16 , Figure 16 This is a structural diagram of another plug-in structure 500 provided in an embodiment of this application. The plug-in structure 500 may include a connecting plate 550, which is disposed between the support ribs 420 of two adjacent first swing arms 400. Both ends of the connecting plate 550 are plugged into the two support ribs 420 respectively. Specifically, a slot 560 is formed on the end face of the support rib 420 facing the connecting plate 550, and the connecting plate 550 is inserted into the slot 560; or, a slot 560 is formed on the side wall of the connecting plate 550 facing the support rib 420, and the support rib 420 is inserted into the slot 560.

[0099] In this way, the connecting plate 550 forms a support between two adjacent support ribs 420 to compensate for the gap between the two adjacent support ribs 420. When the shaft cover 200 is impacted by an external force, and the force point is located between two adjacent support ribs 420, the connecting plate 550 can bear the external force, thereby preventing the shaft cover 200 from hitting the screen.

[0100] Specifically, the aforementioned slot 560 can be formed on the end face of the support rib 420 facing the connecting plate 550, with the connecting end inserted into the slot 560. Furthermore, the slot 560 can extend in a direction perpendicular to the Y direction and penetrate the side wall of the support rib 420. For example, as... Figure 16 As shown, the slot 560 extends in a direction perpendicular to the Y direction and parallel to the X direction, penetrating both side walls of the support rib 420 perpendicular to the X direction. This increases the connection area between the connecting plate 550 and the support rib 420, thereby improving support strength. Furthermore, the connecting plate 550 can be inserted into the slot 560 along the X direction. During production and installation, the support rib 420 can be fixed first, and then the connecting plate 550 can be inserted accordingly, which helps improve installation accuracy and production efficiency.

[0101] In addition, please see Figure 17 and Figure 18 , Figure 17 for Figure 16 A schematic diagram of the improved plug-in structure 500 provided. Figure 18 for Figure 17A partial enlarged view of the provided plug-in structure 500. To prevent the connecting plate 550 and the support rib 420 from separating along the Y direction, the slot 560, in a section perpendicular to its extension direction (i.e., perpendicular to the X direction), has a slot opening width D5 smaller than the slot bottom width D6. Furthermore, the cross-section of the end of the connecting plate 550 inserted into the slot 560 is adapted to the cross-sectional shape of the slot 560.

[0102] For example, please continue reading Figure 17 and Figure 18 The cross-sectional shape of the slot 560 can be approximately a "T" shape, that is, a limiting groove 561 is respectively opened on the two opposite side walls inside the slot 560. A limiting boss 551 is respectively provided on the two opposing surfaces of the end of the connecting plate 550 inserted into the slot 560. When the connecting plate 550 is inserted into the slot 560, the limiting boss 551 is inserted into the limiting groove 561, thereby forming a limiting along the Y-axis direction to prevent the support rib 420 and the connecting plate 550 from separating from each other along the Y direction. This ensures that multiple support ribs 420 and the connecting plate 550 can form a continuous support structure in the Y direction, avoiding gaps.

[0103] The above example shows two adjacent support ribs 420 being interlocked via a plug-in structure 500, thus forming a continuous support structure along the Y direction. In addition, in the rotating mechanism 203 provided in this embodiment, two adjacent support ribs 420 can also be fixedly connected via fasteners 600, thereby forming a continuous support structure in the Y direction. Please refer to... Figure 19 and Figure 20 , Figure 19 This is a structural diagram showing the fixed connection between two adjacent support ribs 420 provided in the application embodiment, using fasteners 600. Figure 20 for Figure 19 A partial structural diagram showing the connection between the provided fastener 600 and two adjacent support ribs 420.

[0104] Specifically, the support ribs 420 of two adjacent first swing arms 400 abut against each other and are locked together by fasteners 600. Thus, since the two adjacent support ribs 420 abut against each other, there is no gap between them. Furthermore, the fasteners 600 increase the support strength at the abutment point between the two adjacent support ribs 420, thereby forming a continuous support structure along the Y direction with multiple support ribs 420, preventing the top screen of the shaft cover 200 from appearing.

[0105] For example, the fastener 600 can be a bolt, screw, pin, etc. By fixing the two ends of the fastener 600 to two adjacent abutting support ribs 420 respectively, the two adjacent support ribs 420 can be locked and fixed, thereby improving the support strength at the abutting point of the two support ribs 420.

[0106] To further enhance the support strength of two adjacent support ribs 420, the contact area between them can be increased. Specifically, along the Y-axis, a portion of the two adjacent support ribs 420 overlaps, and the fastener 600 sequentially penetrates the overlapping area between the two support ribs 420, thereby increasing the support strength between them.

[0107] For example, please continue reading Figure 19 and Figure 20 The two adjacent support ribs 420 include a first support rib 421 and a second support rib 422. A connecting block 610 is fixedly provided on the end face of the first support rib 421 facing the second support rib 422, and a receiving groove 620 is formed on the end face of the second support rib 422 facing the first support rib 421. The end face of the first support rib 421 abuts against the end face of the second support rib 422, and the connecting block 610 is inserted into the receiving groove 620.

[0108] Furthermore, the fastener 600 can be a screw, and the bottom of the connecting block 610 and the receiving groove 620 are provided with threaded holes 630. The screw is inserted into two threaded holes 630 in sequence and engages with the threaded holes 630 to lock the bottom surface of the connecting block 610 and the receiving groove 620. In this way, by inserting the connecting block 610 into the receiving groove 620, the connection area between the first support rib 421 and the second support rib 422 is increased. At the same time, after the first support rib 421 and the second support rib 422 are locked by the screw, when subjected to external impact, the engagement between the screw and the threaded holes 630, as well as the abutment structure between the connecting block 610 and the receiving groove 620, can jointly share the external force, thereby more effectively blocking the external force and preventing the external force from being transmitted to the screen, thus ensuring the integrity of the screen.

[0109] In some embodiments, the receiving groove 620 may extend in a direction perpendicular to the Y direction, for example, extending along the X direction and penetrating at least one of the two side walls of the second support rib 422, to increase the contact area between the connecting block 610 and the receiving groove 620, thereby further enhancing the support strength at the contact point between the first support rib 421 and the second support rib 422.

[0110] Furthermore, the aforementioned fastener 600 can be provided as a single unit or in multiple units. For example, when the overlapping area between the first support rib 421 and the second support rib 422 is large, i.e., when the overall volume of the connecting block 610 is large, multiple threaded holes 630 can be opened on the bottom surfaces of the connecting block 610 and the receiving groove 620 respectively. Simultaneously, multiple screws are provided, each screw being inserted into a threaded hole 630, thereby increasing the connection strength between the bottom surfaces of the connecting block 610 and the receiving groove 620, and consequently improving the support strength at the abutment position between the first support rib 421 and the second support rib 422.

[0111] In summary, in the rotation mechanism 203 provided in this application, the support ribs 420 of two adjacent first swing arms 400 are interlocked by a plug-in structure 500, or the support ribs 420 of two adjacent first swing arms 400 abut against each other and are locked by fasteners 600. This allows the support ribs 420 of the multiple first swing arms 400 to form a continuous support structure along the Y direction, with no gap between adjacent support ribs 420. This effectively prevents deformation of the shaft cover 200 caused by external forces, thus avoiding the transmission of such external forces to the screen and ensuring the integrity of the screen.

[0112] Based on this, to further enhance the overall support strength of the rotating mechanism 203, the rotating mechanism 203 provided in this application embodiment can adopt the same structure as the multiple first swing arms 400. That is, the support ribs 420 of two adjacent second swing arms are also interlocked with each other through the plug-in structure 500, or the support ribs 420 of two adjacent second swing arms abut against each other and are locked and fixed by fasteners 600. Since the specific structure is the same as that of the first swing arm 400, it will not be described again.

[0113] In this way, when the shaft cover 200 is deformed by an external impact, the support ribs 420 of the first swing arm 400 and the support ribs 420 of the second swing arm jointly block the deformation of the shaft cover 200, thereby forming a more effective support to prevent the deformation from being transmitted to the screen and causing the shaft cover 200 to top the screen. Therefore, it can provide better protection for the screen.

[0114] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0115] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
