Description

Technical Field

[0001] The utility model belongs to the field of electronic products, and specifically relates to a rotating shaft structure; it also relates to a folding screen electronic device adopting the rotating shaft structure. Background Art

[0002] As we all know, in order to display more abundant information to users, improve the efficiency of human-computer communication, and enhance the user experience, various electronic equipment terminals (such as mobile phones, tablet computers, etc.) are constantly updated, and the screen size is getting larger and larger. Correspondingly, electronic equipment terminals with large screens will bring inconvenience in carrying and storage. Therefore, in order to solve this problem, folding screen technology came into being, which mainly realizes the folding and unfolding of the screen through two parts of the shell and a rotating shaft structure connected between the two parts of the shell.

[0003] At present, the Chinese patent with the existing publication number CN117072546A discloses a synchronization mechanism, a flexible screen shaft device and a foldable device, in which the synchronization mechanism includes a first swing arm, a second swing arm and a lifting seat, wherein one end of the first swing arm has a first rotating part, the first rotating part is rotatably arranged on the base, and the first swing arm is provided with a first limiting protrusion; one end of the second swing arm has a second rotating part, and the second rotating part is rotatably arranged on the base; the lifting seat is connected to the base, the first swing arm and the second swing arm are connected to both sides of the lifting seat through two transmission parts, and the first swing arm and the second swing arm rotate to drive the lifting seat to slide relative to the base along the Z direction; the transverse limiting member is provided on the base, the transverse limiting member is provided with a first limiting groove, and the first limiting protrusion rotates in the first limiting groove; the flexible screen shaft device includes a rotating assembly, the rotating assembly includes a first rotating member and a second rotating member, one end of the first rotating member and the second rotating member is slidably arranged on the first track and the second track respectively, and the other ends of the first rotating member and the second rotating member are slidably connected to the first swing arm and the second swing arm respectively. In this embodiment, one side of the screen is connected to the first rotating member, and the other side is connected to the second rotating member; that is, by setting a first limit groove on the transverse limit member on the base and a first limit protrusion on the first swing arm, the extreme position of the first swing arm can be limited, thereby limiting the maximum unfolding angle of the flexible screen.

[0004] However, in actual use, the prior art only realizes the extreme position of the swing arm through the cooperation of the limiting protrusion and the limiting groove, but the rotating part directly connected to the flexible screen lacks stop constraints when unfolded. As a result, when the user holds one side of the flexible screen device and unfolds it for use, if the user's hand shakes, the other side of the flexible screen will easily shake significantly due to inertia, thereby affecting the user experience. Summary of the invention

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved rotating shaft structure.

[0006] At the same time, the utility model also provides a folding screen electronic device.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A rotating shaft structure, comprising:

[0009] Pedestal;

[0010] The torsion module comprises two rotating arms respectively connected to the left and right sides of the base, and a torsion component arranged between the two rotating arms;

[0011] The connecting module comprises a connecting module correspondingly slidably connected to each rotating arm,

[0012] A first stop portion is formed on each rotating arm, and a second stop portion matching the first stop portion is formed on each connecting module, wherein the two rotating arms are folded relative to each other, and the first stop portion and the second stop portion are synchronously disengaged from each other; the two rotating arms are relatively flattened, and each first stop portion is synchronously abutted against the corresponding second stop portion, and a resistance is formed to prevent the corresponding connecting module and the rotating arm from sliding relative to each other.

[0013] According to a specific implementation and preferred aspect of the utility model, the first stop portion has a first stop surface, and the second stop portion has a second stop surface. When the two rotating arms are relatively flattened, the corresponding first stop surface and the second stop surface are arranged in contact with each other. In the flattened state, a larger contact surface can be formed between the first stop portion and the second stop portion, which is conducive to further enhancing the structural strength; at the same time, the first stop surface and the second stop surface form a surface contact through the friction, which can form friction during folding or unfolding, thereby providing a damping feeling and improving the user's feel.

[0014] Preferably, when the two rotating arms are relatively flattened, each first stop surface is located on the inner side of the corresponding second stop surface, and each second stop portion is kept pressed against the corresponding first stop portion in the direction of the base. Here, while the connection module forms a stop limit, it can also simultaneously press against the rotating arm, thereby improving the stability of the rotating shaft structure in the flattened state.

[0015] Preferably, when the two rotating arms are relatively flattened, each first stop surface and / or second stop surface is arranged perpendicular to the flattened plane formed by the two rotating arms.

[0016] According to another specific implementation and preferred aspect of the utility model, a first inclined surface adjacent to the first stop surface is further formed on the first stop portion, and a second inclined surface adjacent to the second stop surface is further formed on the second stop portion, and when the two rotating arms are relatively flattened, the corresponding first inclined surface and second inclined surface are parallel and spaced apart. Here, based on the premise that the connection module slides relative to the rotating arm, interference between the two is avoided, thereby improving the reliability of the structure.

[0017] Preferably, the angle between the first stop surface and the corresponding first inclined surface is 100° to 145°; and / or the angle between the first stop surface and the corresponding first inclined surface is equal to the angle between the second stop surface and the corresponding second inclined surface.

[0018] Preferably, the first stopper extends outward from one side, and the adjacent two sides of the first stopper respectively form a first stopper surface and a first inclined surface; and / or, a notch groove is formed on the second stopper, wherein the adjacent two side walls in the notch groove respectively form a second stopper surface and a second inclined surface. Here, the structure is simple, and it is easy to process and implement.

[0019] According to another specific implementation and preferred aspect of the utility model, the torsion component includes a plurality of shaft cores arranged on a base and arranged side by side and spaced apart along the left-right direction, a connecting plate connected to one end of the plurality of shaft cores, a plurality of gears fixedly connected to each shaft core located in the middle and meshing in sequence, two cam pieces sleeved on the plurality of shaft cores and spaced apart along the length direction of the shaft cores, and a plurality of springs correspondingly sleeved on each shaft core and abutting between the corresponding cam piece and the connecting plate from both ends, wherein two rotating arms are respectively sleeved from one end on the two shaft cores located on both sides and are located between the two cam pieces, a tooth meshing with the corresponding gear is formed on the end of each rotating arm, and the end of each rotating arm meshes with the corresponding cam piece from both end surfaces.

[0020] Preferably, the connecting plate is made of sheet metal, which is simple to process, easy to repair and replace, and low in cost.

[0021] Preferably, the torsion component further comprises a retaining spring sleeved on one end of the plurality of shaft cores, and the connecting plate abuts against the inner side of the retaining spring.

[0022] Another technical solution of the utility model is a folding screen electronic device, which includes a casing, the casing includes a left shell and a right shell, the electronic device also includes the above-mentioned shaft structure, and the left shell and the right shell are respectively fixedly connected to the left and right connecting modules.

[0023] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:

[0024] The prior art only realizes the extreme position of the swing arm through the cooperation of the limiting protrusion and the limiting groove, but the rotating part directly connected to the flexible screen lacks a stop constraint when unfolded. As a result, when the user holds one side of the flexible screen device and unfolds it for use, if the user shakes his hand, the other side of the flexible screen will easily produce obvious shaking under inertia, thereby affecting the user experience. The present application designs the hinge structure and the structure of the folding screen electronic device as a whole, cleverly solving the deficiencies and defects of the prior art. After adopting the hinge structure, when the left and right rotating arms are relatively folded, the first stop portion and the second stop portion are synchronously disengaged, and the connection module is in an unstopped state, which can When the left and right rotating arms are relatively flattened, each first stop portion is synchronously abutted against the corresponding second stop portion, and a resistance is formed to prevent the corresponding connecting module from sliding relative to the rotating arm, so as to stop and limit the connecting module and reduce the shaking caused by external force. Therefore, compared with the prior art, the utility model can, on the one hand, stop and limit the connecting module through the cooperation of the first and second stop portions in the flattened state, thereby improving the anti-destructive force of the rotating shaft structure in the flattened state and reducing the shaking phenomenon caused by external force, thereby effectively improving the user experience; on the other hand, the structure is simple and reliable, and the implementation cost is low.

[0042] In this example, the connection module 3 includes a connection module 30 correspondingly slidably connected to each rotating arm 21 .

[0043] In some specific embodiments, a slide groove matching the corresponding rotating arm 21 is formed on each connecting module 30 , and the rotating arm 21 is inserted into the slide groove and can slide along the slide groove during rotation.
