Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 8 shown, an embodiment of the present invention provides a limiting structure applied to a three-screen device, including:

[0031] A middle screen 1; a first screen 2, the first screen 2 is connected to the middle screen 1 and can rotate relative to the middle screen 1 for folding; a second screen 3, the second screen 3 is connected to the other side of the middle screen 1 relative to the first screen 2 and can rotate relative to the middle screen 1 for folding; the middle screen 1 is provided with a limiting structure 11, the second screen 3 is provided with a second limiting part 31, when the limiting structure 11 is in an open state, it can limit the folding of the first screen 2, and during the folding process of the second screen 3, through the cooperation of the second limiting part 31 and the limiting structure 11, the limiting structure 11 can be in a closed state, and then the second screen 3 can be folded first, and the first screen 2 can be folded later.

[0032] Specifically, the cooperation between the second limiting part 31 and the limiting structure 11 is a contact type cooperation, and the limiting structure 11 retracts into the closed state during the contact process with the second limiting part 31; the contact surfaces of the limiting structure 11 and the second limiting part 31 have a specific texture design to enhance the contact stability between the two and reduce the possibility of accidental sliding;

[0033] The cooperation between the second limiting part 31 and the limiting structure 11 can also be designed as an inductive cooperation. By arranging sensors on the second limiting part 31 and the limiting structure 11, the sensors can sense the position of the second limiting part 31 during the rotation and folding of the second screen 3, so that the limiting structure 11 enters the closed state, ensuring that the second screen 3 can be folded smoothly and improving the convenience of folding.

[0034] Further, the limiting structure 11 is provided with a limiting contact part 111, a limiting fixing block 112, and an elastic connecting part.

When the limiting contact part 111 contacts the second limiting part 31, the guiding protrusion can guide it to smoothly enter the limiting position to reduce the possibility of misoperation; each component of the limiting structure 11 is connected by a detachable connecting part, which is convenient for maintenance and replacement, reduces the maintenance cost and improves the service life of the product.

[0035] Still further, the limiting contact part 111 is provided with an elastic part mounting post 1111 and a limiting contact part body 1112.

[0036] Even further, the contact end of the limiting contact part body 1112 is designed with a chamfer, and the chamfer is an arc-shaped chamfer to ensure that the friction is reduced when the limiting contact part body 1112 contacts the second limiting part 31, so as to reduce the wear of the limiting contact part body 1112 and extend the service life; after the chamfer of the limiting contact part body 1112 contacts the second limiting part 31, it retracts, so that the limiting structure 11 enters the closed state; a wear-resistant coating is also coated on the chamfer surface of the limiting contact part body 1112 to increase its wear resistance and service life and reduce the wear during multiple contact processes; tiny elastic buffer parts are also provided at the chamfer of the limiting contact part body 1112, and these elastic buffer parts can provide additional buffer force during contact, further reducing the impact and wear during the contact process.

[0037] Furthermore, the second limiting portion 31 is provided with a guiding surface 311, which is designed with an inclined angle to ensure a smooth transition when the limiting contact member body 1112 comes into contact, so as to reduce friction and wear; during the process of the limiting contact member body 1112 contacting the guiding surface 311, it can retract, and the limiting structure 11 can enter the closed state from the open state; the guiding surface 311 of the second limiting portion 31 can also be designed as a multi-segment structure, with each segment having a different guiding angle, so as to achieve a staged limiting and retracting process, and increase the stability and accuracy of the limiting structure 11.

[0038] Furthermore, the limiting structure 21 is arranged on the upper side edge of the middle screen 1, and the second limiting portion 31 is correspondingly arranged on the upper side edge of the second screen 3. The second limiting portion 31 can accurately abut against the limiting structure 21 to achieve a stable limiting effect; a wear-resistant gasket is also provided on the contact surface between the limiting structure 21 and the second limiting portion 31 to reduce the friction and wear generated during multiple folding processes and extend the service life of the component; the contact surface between the limiting structure 21 and the second limiting portion 31 can also be designed as a magnetic contact surface, and the stable contact between the two during the folding process is ensured through magnetic adsorption to prevent accidental sliding and displacement.

[0039] Furthermore, the middle screen 1 is also provided with an upper protection device 12. The upper protection device 12 is provided with a limiting structure installation position 121, and the limiting structure installation position 121 is provided with a guiding groove. The limiting structure 11 is connected in the guiding groove through an elastic connecting piece and can move axially in the guiding groove, so as to realize the conversion between the open state and the closed state of the limiting structure 11; the upper protection device 12 is made of a high-strength wear-resistant material to ensure its durability and reliability during long-term use, and at the same time provide effective protection for the limiting structure 11.

[0040] Still further, the upper protection device 12 is also provided with a locking device 122. The locking device 122 is arranged on both sides of the upper protection device 12. The locking device 122 includes a locking hook and a locking groove. The locking hook is elastically connected to the upper protection device 12, and the locking groove is arranged on the base of the three-screen device. When the locking device 122 is in the locked state, the locking hook can be inserted into the locking groove, so as to realize the stable fixation of the three-screen device.

The first upper connecting portion 21 and the first lower connecting portion 22 are respectively rotatably connected to the first upper rotating shaft 13 and the first lower rotating shaft 14 to limit the rotation range of the first screen 2, and the second upper connecting portion 32 and the second lower connecting portion 33 are respectively rotatably connected to the second upper rotating shaft 15 and the second lower rotating shaft 16 to limit the rotation range of the second screen 3, so that the first screen 2 and the second screen 3 can be stably unfolded, improving the use stability of the three-screen device.

[0043] The first upper connecting portion 21 and the first lower connecting portion 22 of the present utility model are provided with a first rotating shaft rod. The first rotating shaft rod is provided with a first inclined surface, and the first inclined surface can abut against the middle screen 1, so as to facilitate the first screen 2 to be stably unfolded, improving the stability of the first screen 2 after unfolding and enhancing the user experience.
