Description

Technical Field

[0001] The present application relates to the technical field of folding screens, and in particular, to a rotating shaft structure, a dual-axis structure, and a folding screen. Background Art

[0002] A folding screen is an innovative display technology that allows the screen to be folded or unfolded while maintaining a certain degree of flexibility. This technology is mainly applied to electronic devices such as smartphones and tablets, bringing users a more convenient and diverse usage experience.

[0003] However, folding screen technology also faces some challenges, such as screen durability, crease problems, high prices, etc. With the continuous progress of technology and the reduction of costs, a technology for folding hard screens has been designed, that is, a hinge is installed between two hard screens to avoid the bending problem of the folding screen.

[0004] The invention patent with the patent number CN113009967B discloses a hinge assembly for a foldable screen, including: a support member; a first gear rotatably provided on the support member, a first connecting shaft being provided on a first side of the first gear; a second gear rotatably provided on the support member, the second gear meshing with the first gear, a second connecting shaft being provided on a first side of the second gear, the second connecting shaft being eccentrically provided with respect to the axis of the second gear; a movable rod provided with a plurality of positioning grooves; a positioning slider connected to the second connecting shaft, the positioning slider being capable of being engaged with the positioning grooves. However, if a hinge design is adopted, since the hard screen has a thickness, gaps will be generated between the two hard screens during the flipping process to avoid interference, and there are protrusions at the folding position, thus causing aesthetic problems between the two hard screens, and this problem urgently needs to be improved. Summary of the Utility Model

[0005] In order to reduce the gaps generated after the screen is flipped, thereby being beneficial to improving the aesthetics of the hard screen folding screen, the present application provides a rotating shaft structure, a dual-axis structure, and a folding screen.

[0006] The rotating shaft structure, dual-axis structure, and folding screen provided by the present application adopt the following technical solutions:

[0007] A rotating shaft structure includes a mounting base, a hinge member is rotatably connected to the mounting base. The hinge member includes an integrally formed first connecting portion, a transition portion, and a second connecting portion. The first connecting portion and the second connecting portion are located at both ends of the transition portion. The first connecting portion is provided with a rotating and sliding groove. The hinge member is rotatably connected to the mounting base through the first connecting portion, and the first connecting portion slides along the length direction of the rotating and sliding groove. The mounting base is provided with a rotating shaft, and a limiting and anti-detaching member synchronously rotating with the hinge member is connected to the rotating shaft. The limiting and anti-detaching member and the first connecting portion are arranged in a dislocation manner on the mounting base. The second connecting portion is provided with a slot. One end of the limiting and anti-detaching member is rotatably connected to the mounting base through the rotating shaft, and the other end of the limiting and anti-detaching member is inserted into the slot and makes a telescopic movement relative to the length direction of the slot along with the rotation of the hinge member. The length direction of the rotating and sliding groove intersects with the length direction of the slot.

[0008] By adopting the above technical solution, the mounting base supports the rotating shaft, the hinge member, and the limiting and anti-detaching member. In the hinge member, the transition portion connects the first connecting portion and the second connecting portion together. The hinge member is rotatably connected to the mounting base through the first connecting portion. The rotating and sliding groove provided in the first connecting portion enables the hinge member to slide synchronously along the length direction of the rotating and sliding groove during the rotation on the mounting base. One rigid screen in the folding screen can be fixedly connected to the hinge member through the second connecting portion. The hinge member drives the rigid screen to rotate and move. One end of the limiting and anti-detaching member is rotatably connected to the rotating shaft, and the other end of the limiting and anti-detaching member is inserted into the slot to make a telescopic movement. The telescopic movement direction of the limiting and anti-detaching member intersects with the sliding movement direction of the first connecting portion, making it difficult for the hinge member to detach from the mounting base, and is beneficial to improving the stability of the movement of the hinge member. When the rigid screen is mounted on the hinge member, the hinge member drives the rigid screen to perform a flipping movement with axial movement, so that the edge position of the rigid screen can remain unchanged during the movement. When two rigid screens form a folding screen flipping structure, the edges of the two rigid screens always abut against each other, reducing the gap generated after the screen is flipped, thereby being beneficial to improving the aesthetics of the rigid screen folding screen.

[0009] Preferably, the vertical cross-section of the transition portion is arranged in an L shape, and the first connecting portion and the second connecting portion form a step through the transition portion.

[0010] By adopting the above technical solution, this setting enables the first connecting portion and the second connecting portion to have a height difference to form a dislocation, which is beneficial to avoiding the situation of jamming when the limiting and anti-detaching member rotates when inserted into the slot.

[0011] Preferably, a rotating arc surface is provided at the position where the limiting and anti-detaching member rotates with the rotating shaft.

[0012] By adopting the above technical solution, rotating the arc surface makes it difficult for the limit anti-disengagement member to interfere with other structures in the rotating shaft structure during the rotation process.

[0013] Preferably, two limit anti-disengagement members are provided, and the two limit anti-disengagement members are respectively arranged on both sides of the first connection portion in the length direction relative to the mounting seat.

[0014] By adopting the above technical solution, the two limit anti-disengagement members are respectively arranged on both sides of the first connection portion to jointly prevent the hinge member from disengaging from the mounting seat, and is beneficial to improving the stability of the hinge member during operation.

[0015] Preferably, it further includes a damping component for keeping the limit anti-disengagement member in a staying state on the mounting seat. The damping component includes a spring and a damping block. The damping block is located on the side of the limit anti-disengagement member away from the first connection portion and is movably sleeved on the rotating shaft. The spring is in a compressed state on the side of the damping block away from the limit anti-disengagement member.

[0016] By adopting the above technical solution, when the hinge member is flipped to a certain angle, the compressed spring pushes the damping block to move towards the limit anti-disengagement member, so that the damping block presses the limit anti-disengagement member tightly on the mounting seat. Without external force, it is difficult for the limit anti-disengagement member and the hinge member to move, which is beneficial to improving the stability of the limit anti-disengagement member and the hinge member when staying.

[0017] Preferably, two sets of damping components are provided, and the two sets of damping components respectively perform pressing operations corresponding to the two limit anti-disengagement members.

[0018] By adopting the above technical solution, the two sets of damping components respectively perform pressing operations on the corresponding two limit anti-disengagement members, which is beneficial to further improving the stability of the limit anti-disengagement member and the hinge member when staying.

[0019] A double-shaft structure includes the above rotating shaft structure. Two rotating shafts are arranged side by side. The mounting seat is provided with a connecting member for connecting the limit anti-disengagement members on the two rotating shafts. The rotation of one set of limit anti-disengagement members drives the synchronous rotation of the other set of limit anti-disengagement members through the connecting member.

[0020] By adopting the above technical solution, the limit anti-disengagement members on the two rotating shafts are connected together by the connecting member. When the user applies force to the hinge member on one rotating shaft and it flips, the limit anti-disengagement member on this rotating shaft rotates synchronously. The rotating limit anti-disengagement member drives the limit anti-disengagement member on the other rotating shaft to rotate synchronously through the connecting member, so that the hinge member on the other rotating shaft performs a flipping movement, and the operation is convenient and fast.

[0021] Preferably, connecting rods are provided at both ends of the connecting member. Connecting grooves for the connecting rods to penetrate are correspondingly formed in the two limiting and anti - detachment members, and the connecting rods penetrating into the connecting grooves can move along the length direction of the connecting grooves. One of the limiting and anti - detachment members is provided with a pushing member for pushing the connecting member to move.

[0022] By adopting the above - mentioned technical solution, the connecting rods at both ends of the connecting member penetrate into the connecting grooves of the two limiting and anti - detachment members respectively to realize the connection of the two limiting and anti - detachment members. When one of the limiting and anti - detachment members rotates, the pushing member pushes the connecting member to move, and the moving connecting member drives the other limiting and anti - detachment member to rotate, thereby realizing the synchronous rotation of the two limiting and anti - detachment members in opposite directions.

[0023] Preferably, the pushing member is set as a pushing block. A pushing groove is formed in the pushing block. The pushing groove has an intersecting first pushing surface and second pushing surface. A convex block is provided at the position of the connecting member corresponding to the pushing groove. When the limiting and anti - detachment member rotates, the first pushing surface abuts against and pushes the convex block. When the limiting and anti - detachment member rotates in the reverse direction, the second pushing surface abuts against and pushes the convex block in the reverse direction.

[0024] By adopting the above - mentioned technical solution, the convex block penetrates into the pushing groove formed in the pushing block. When the limiting and anti - detachment member rotates, the first pushing surface abuts against and pushes the convex block to move in the direction close to the other limiting and anti - detachment member. The convex block synchronously drives the connecting member to move in the direction close to the other limiting and anti - detachment member, and the other limiting and anti - detachment member rotates in the opposite direction correspondingly. Similarly, when the limiting and anti - detachment member rotates in the reverse direction, the second pushing surface abuts against and pushes the convex block to move in the direction away from the other limiting and anti - detachment member. The convex block synchronously drives the connecting member to move in the direction away from the other limiting and anti - detachment member, and the other limiting and anti - detachment member also rotates in the opposite direction.

[0025] A folding screen includes the above - mentioned double - axis structure, and also includes two rigid screens. The two rigid screens are respectively wrapped and fixed on the two hinge members. The two rigid screens respectively symmetrically cover half of the position of the mounting seat, and the opposite side edges of the two rigid screens always abut against each other.

[0026] By adopting the above - mentioned technical solution, the two rigid screens are respectively wrapped and fixed on the two hinge members to form a folding screen, and the edges of the two rigid screens abut against each other. When the folding screen is flipped, the edges of the two rigid screens always remain in an abutting state, which is beneficial to reducing the gap generated after the screen is flipped, and thus is beneficial to improving the aesthetics of the rigid - screen folding screen.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. By setting the synchronously rotating hinge member and the limit anti-disengagement member, the hinge member is rotationally connected to the mounting seat through the first connecting portion. The rotation sliding groove formed in the first connecting portion enables the hinge member to perform a sliding movement synchronously along the length direction of the rotation sliding groove during the rotation on the mounting seat. One rigid screen in the folding screen can be fixedly connected to the hinge member through the second connecting portion. The hinge member drives the rigid screen to perform rotational and translational movements. One end of the limit anti-disengagement member is rotationally connected to the rotating shaft, and the other end of the limit anti-disengagement member is inserted into the slotted groove for telescopic movement. The telescopic movement direction of the limit anti-disengagement member intersects with the sliding movement direction of the first connecting portion, making it difficult for the hinge member to disengage from the mounting seat, and facilitating the improvement of the stability of the hinge member's movement. When the rigid screen is mounted on the hinge member, the hinge member drives the rigid screen to perform a flipping movement with axial movement, so that the edge position of the rigid screen can remain unchanged during the movement. When two rigid screens form a folding screen flipping structure, the edges of the two rigid screens always abut against each other, reducing the gap generated after the screen is flipped, thereby facilitating the improvement of the aesthetic appearance of the rigid screen folding screen.

[0029] 2. By setting the connecting member, the limit anti-disengagement members on the two rotating shafts are connected together through the connecting member. When the user applies force to the hinge member on one rotating shaft to cause flipping, the limit anti-disengagement member on this rotating shaft rotates synchronously. The rotating limit anti-disengagement member drives the limit anti-disengagement member on the other rotating shaft to rotate synchronously through the connecting member, so that the hinge member on the other rotating shaft performs a flipping movement, and the operation is convenient and fast.

[0030] 3. The pushing groove has intersecting first and second pushing surfaces. When the limit anti-disengagement member rotates, the first pushing surface abuts against the pushing convex block and moves it in the direction close to the other set of limit anti-disengagement members. The convex block synchronously drives the connecting member to move in the direction close to the other set of limit anti-disengagement members, and the other set of limit anti-disengagement members rotates in the opposite direction correspondingly. Similarly, when the limit anti-disengagement member rotates in the reverse direction, the second pushing surface abuts against the pushing convex block and moves it in the direction away from the other set of limit anti-disengagement members. The convex block synchronously drives the connecting member to move in the direction away from the other set of limit anti-disengagement members, and the other set of limit anti-disengagement members also rotates in the opposite direction.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-12 This application is described in further detail.

[0046] The present application embodiment discloses a rotating shaft structure, referring to Figure 1 and Figure 2, including a mounting base 1, which is arranged in a long strip shape. The mounting base 1 is provided with a first mounting groove 18 and a second mounting groove 19 at intervals along its length direction. The mounting base 1 is rotatably connected with a hinge member 2 through the first mounting groove 18, and the mounting base 1 is rotatably connected with a limit anti - detachment member 5 through the second mounting groove 19, and the hinge member 2 and the limit anti - detachment member 5 rotate synchronously.

[0047] Refer to Figure 1 and Figure 3 , the hinge member 2 includes an integrally formed first connecting portion 21, a transition portion 22 and a second connecting portion 23. The first connecting portion 21 is arranged in an inclined block shape, the vertical cross - section of the transition portion 22 is arranged in an L shape, and the second connecting portion 23 is arranged in a straight plate shape. The first connecting portion 21 and the second connecting portion 23 are fixedly connected to both ends of the transition portion 22, so that the first connecting portion 21 forms a step with the second connecting portion 23 through the transition portion 22. A rotation and sliding groove 3 is formed in the side wall of the first connecting portion 21 along its inclined direction, and the rotation and sliding groove 3 is set as a through - groove. Refer to Figure 2 , the hinge member 2 is connected to the mounting base 1 by inserting the first connecting portion 21 into the first mounting groove 18. At the same time, a guide post 20 is vertically arranged on the groove wall of the first mounting groove 18, and the guide post 20 is inserted into the rotation and sliding groove 3, so that the first connecting portion 21 can rotate around the guide post 20 in the first mounting groove 18, and the first connecting portion 21 can slide along the length direction of the rotation and sliding groove 3.

[0048] Refer to Figure 2 and Figure 3 , through the above - mentioned method, the hinge member 2 can realize the actions of rotating and sliding on the mounting base 1, but the hinge member 2 is easily detached from the mounting base 1. The setting of the limit anti - detachment member 5 ensures the stability of the connection between the hinge member 2 and the mounting base 1 while not interfering with the action of the hinge member 2. Refer to Figure 1 and Figure 4, a rotating shaft 4 is fixedly arranged along the length direction of the mounting base 1. The limiting and anti-disengagement member 5 is inserted into the second mounting groove 19 and rotatably connected to the rotating shaft 4. The limiting and anti-disengagement member 5 and the first connecting portion 21 are arranged in a staggered manner on the mounting base 1. It should be noted that in order to fit the shape of the hinge member 2, the vertical cross-section of the limiting and anti-disengagement member 5 is arranged in a Z shape. At the same time, a slot 6 is formed in the side wall of the second connecting portion 23 along the direction parallel to the plate surface. One end of the limiting and anti-disengagement member 5 is inserted into the second mounting groove 19 and rotatably connected to the rotating shaft 4 to realize the rotational connection with the mounting base 1. The other end of the limiting and anti-disengagement member 5 is inserted into the slot 6 and makes a telescopic movement relative to the length direction of the slot 6 following the rotation of the hinge member 2, so as to realize the synchronous rotation of the limiting and anti-disengagement member 5 and the hinge member 2. It is worth mentioning that the length direction of the rotation and sliding groove 3 intersects with the length direction of the slot 6, so that the direction in which the hinge member 2 disengages from the first mounting groove 18 intersects with the direction in which the hinge member 2 disengages from the limiting and anti-disengagement member 5. While ensuring the actions of the hinge member 2 and the limiting and anti-disengagement member 5, it is difficult for the hinge member 2 to disengage from the mounting base 1.

[0049] Referring to Figure 4 , a rotating arc surface 7 is arranged at the position where the limiting and anti-disengagement member 5 rotates with the rotating shaft 4, so that when the limiting and anti-disengagement member 5 rotates, the shape of the position where the limiting and anti-disengagement member 5 is connected to the rotating shaft 4 remains unchanged, and it will not interfere with other structures in the structure of the rotating shaft 4. Referring again to Figure 1 and Figure 2 , the number of the limiting and anti-disengagement members 5 is set to two. The two limiting and anti-disengagement members 5 are respectively arranged on both sides of the first connecting portion 21 relative to the length direction of the mounting base 1. Correspondingly, the second mounting groove 19 is also set to two for the two limiting and anti-disengagement members 5 to be inserted respectively, so as to improve the anti-disengagement effect and at the same time be beneficial to improving the movement stability of the hinge member 2.

[0050] Referring to Figure 1 , the rotating shaft structure further includes a damping assembly 8 for keeping the limiting and anti-disengagement member 5 in a staying state on the mounting base 1, that is, when the hinge member 2 and the limiting and anti-disengagement member 5 rotate a certain angle, the damping assembly 8 keeps the staying state of the limiting and anti-disengagement member 5. Without the action of external force, it is difficult for the limiting and anti-disengagement member 5 to rotate. Specifically, the damping assembly 8 includes a spring 81 and a damping block 82. The damping block 82 is located on the side of the limiting and anti-disengagement member 5 away from the first connecting portion 21 and is movably sleeved on the rotating shaft 4. The spring 81 is located on the side of the damping block 82 away from the limiting and anti-disengagement member 5 and is in a compressed state, so that the damping block 82 abuts against the side wall of the limiting and anti-disengagement member 5 to keep the stability of the limiting and anti-disengagement member 5 without the action of external force, thereby keeping the stability of the hinge member 2. The damping principle will not be elaborated here. In this embodiment, two groups of damping assemblies 8 are provided, and the two groups of damping assemblies 8 respectively perform tightening operations on the two limiting and anti-disengagement members 5, so as to further improve the stability of the limiting and anti-disengagement member 5 and the hinge member 2 in the staying state.

[0051] The implementation principle of a rotating shaft structure in an embodiment of the present application is as follows: when the hinge member 2 rotates on the mounting base 1, the hinge member 2 synchronously moves along the length direction of the rotating sliding groove 3, so as to realize the rotational operation of the rotation axis of the hinge member 2 moving. During the movement of the hinge member 2, the hinge member 2 drives the limit and anti-disengagement member 5 to rotate synchronously, and the limit and anti-disengagement member 5 makes a telescopic movement in the second connecting portion 23 through the slot 6. The length direction of the rotating sliding groove 3 intersects with the length direction of the slot 6, so that the direction in which the hinge member 2 disengages from the first installation groove 18 intersects with the direction in which the hinge member 2 disengages from the limit and anti-disengagement member 5. While ensuring the actions of the hinge member 2 and the limit and anti-disengagement member 5, it is difficult for the hinge member 2 to disengage from the mounting base 1.

[0052] The embodiment of the present application also discloses a double-shaft structure. Refer to Figure 5 、 Figure 6 and Figure 7 , which includes two sets of the above-mentioned rotating shaft structures. The two sets of rotating shaft structures are symmetrically installed on the same mounting base 1. Among them, there are two rotating shafts 4 arranged side by side. At the same time, the mounting base 1 is provided with a connecting member 9 for connecting the limit and anti-disengagement members 5 on the two rotating shafts 4. The rotation of one set of limit and anti-disengagement members 5 drives the other set of limit and anti-disengagement members 5 to rotate synchronously and in the opposite direction through the connecting member 9.

[0053] Refer to Figure 8 and Figure 9 , the connecting member 9 is arranged in a long strip shape at the position between the two sets of rotating shaft structures. Both ends of the connecting member 9 are fixedly provided with connecting rods 10. The two connecting rods 10 are both perpendicular to the connecting member 9 and extend from the same side of the connecting member 9. At the same time, the limit and anti-disengagement members 5 in the two sets of rotating shaft structures are correspondingly provided with connecting grooves 11 for the connecting rods 10 to penetrate. And the connecting rods 10 penetrating into the connecting grooves 11 can move along the length direction of the connecting grooves 11. One set of limit and anti-disengagement members 5 is fixedly provided with a pushing member for pushing the connecting member 9 to move.

[0054] Refer to Figure 8 and Figure 9, the driving member is arranged as a driving block 12. The driving block 12 is provided with a driving groove 13. The driving groove 13 has an intersecting first driving surface 14 and a second driving surface 15. The first driving surface 14 and the second driving surface 15 are connected to form the groove surface of the driving groove 13. At the same time, a convex block 16 is fixedly arranged at the position of the connecting member 9 corresponding to the driving groove 13. The convex block 16 is inserted into the driving groove 13. When a group of limiting and anti-disengaging members 5 rotates, the first driving surface 14 abuts against the driving convex block 16 and drives the connecting member 9 to move towards the direction close to the other group of limiting and anti-disengaging members 5, so that the connecting member 9 drives the other group of limiting and anti-disengaging members 5 to rotate in the opposite direction through the connecting rod 10 at the other end. When the limiting and anti-disengaging members 5 rotate in the opposite direction, the second driving surface 15 abuts against the driving convex block 16 in the reverse direction and drives the connecting member 9 to move away from the other group of limiting and anti-disengaging members 5, so that the connecting member 9 drives the other group of limiting and anti-disengaging members 5 to rotate through the connecting rod 10 at the other end. The rotation directions of the two groups of limiting and anti-disengaging members 5 are always opposite. The two groups of limiting and anti-disengaging members 5 rotating in opposite directions synchronously drive the two groups of hinge members 2 to rotate in opposite directions, so that the opening and closing operation formed by the double-axis structure is more convenient and fast.

[0055] The implementation principle of a double-axis structure in an embodiment of the present application is: the connecting member 9 connects the two groups of rotating shaft structures together. When a flipping operation is performed on one group of rotating shaft structures, the other group of rotating shaft structures synchronously perform a flipping operation in the opposite direction, so that the opening and closing operation formed by the two hinge members 2 on the double-axis structure is more convenient and fast.

[0056] An embodiment of the present application also discloses a folding screen. Refer to Figure 10 , Figure 11 and Figure 12 , including the above double-axis structure, and further including two rigid screens 17. The two rigid screens 17 have a thickness. The two rigid screens 17 are respectively wrapped and fixed on the two hinge members 2. The two rigid screens 17 respectively symmetrically cover half of the position of the mounting base 1, and the opposite side edges of the two rigid screens 17 always abut. When the two rigid screens 17 perform a flipping and folding operation, the axes of the rigid screens 17 during flipping can move synchronously, so that the abutting edges of the two rigid screens 17 are always in an abutting state, and no gap is generated during the flipping process of the folding screen, which is beneficial to improving the aesthetics of the rigid screen 17 folding screen.

[0057] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
