Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The embodiment of the present invention provides an adjustable connecting mechanism 20 for connecting two adjacent display units 10 in a rollable mechanism of a display device, including: a connection box 21 and two connection members, the structure of which can be seen in fig. 1 and 2;
wherein, the connecting box 21 is internally provided with an installation cavity, the first ends of the two connecting pieces are both positioned in the installation cavity, and the second ends of the two connecting pieces are respectively used for connecting the display units 10 at the two sides;
the first end of at least one connecting piece is in sliding fit with the mounting cavity;

It can be seen from the above technical solutions that, the adjustable connection mechanism 20 provided in the embodiment of the present invention is matched with the display units on both sides through the connection box 21 and the connection piece in a rollable manner, and because the first end of the connection piece is matched with the installation cavity in a slidable manner, the distance between two adjacent display units 20 can be changed, so that the connection mechanism can be adjusted in length along the circumferential direction when the display device is rolled, thereby avoiding that the flexible screen is not rolled or damaged due to errors such as production and assembly, and the like.
Preferably, the at least one connector comprises: a slider 22 and a link 23, the structure of which can be seen in fig. 3 and 4;
wherein, the slide block 22 is connected to the first end of the connecting rod 23, and is used as the first end of the connecting piece, and the slide block 22 is in sliding fit with the installation cavity to realize the length adjustment;
the second end of the link 23 is used for connecting the display unit 10 as the second end of the connecting member. The link 23 is disposed such that a certain distance exists between the two end members (the slider 22 and the display unit 10) to provide a moving space for the components to cooperate with each other, for example, to prevent the display unit 10 from interfering with the connecting box 21 when rotating. Specifically, the slider 22 and the link 23 may be integrally formed.
Further, both connecting pieces comprise a sliding block 22 and a connecting rod 23, and the two sliding blocks 22 are respectively in sliding fit with the mounting cavity. That is, the distance between the display units 20 on both sides and the connection box 21 can be adjusted, which is more convenient and flexible in the curling and unfolding operations. Of course, the display device can be rolled up and unrolled even when only the one-side link has the slider 22 and link 23 structure as described above.
In the first embodiment provided by the present disclosure, the slider 22 is a spherical slider, the slider 22 is fixedly connected to the first end of the connecting rod 23, and the second end of the connecting rod 23 is used for fixedly connecting the display unit 10, and the structure thereof can be shown in fig. 5 to 10. That is, the spherical slider 22 can rotate in addition to sliding in the mounting cavity, so that the display unit 10 and the connecting box 21 can rotate relatively. Preferably, the inner wall of the mounting cavity is cylindrical in shape to mate with the ball-type slider 22. The length of the installation cavity (corresponding to the sliding direction) is more than 2 times of the diameter of the sphere of the sliding block 22, so that a sliding space is reserved; the length of the installation cavity is less than 3 times of the diameter of the sphere of the sliding block 22, so that the excessive space is avoided being occupied, and specific numerical values can be determined according to actual conditions and are not repeated.
In a second specific embodiment provided by the present solution, the sliding block 22 is a square sliding block, and the structure thereof can be shown in fig. 11; correspondingly, the inner wall of the mounting cavity is in a cuboid shape matched with the square slide block 22;
wherein the slider 22 is hinged to a first end of the link 23 and/or a second end of the link 23 is used to hinge the display unit 10. Namely, compared with the first embodiment, the present solution is different in that the square slider 22 is slidably engaged with the mounting cavity, and the display unit 10 and the connection box 21 are relatively rotated by the hinge structure at the end of the connecting rod 23.
In order to further optimize the above technical solution, the connecting box 21 is provided with a guide groove 24, the sliding fit direction of the slider 22 and the mounting cavity is parallel to the guide direction of the guide groove 24, and the structure thereof can be shown in fig. 3, 7 and 11;
wherein, the width of the guide slot 24 is larger than the external dimension of the connecting rod 23, so as to facilitate the free sliding of the connecting rod 23 in the guide slot 24; smaller than the outer dimension of the slider 22 to prevent the slider 22 from being removed from the guide groove 24.
Specifically, the connecting piece is made of elastic materials, and can deform to a certain extent when the display device is curled or unfolded, so that the operation is convenient. For example, the material of the sliding block 22 is an elastic material with excellent elasticity, and an elastic material such as a rubber material or an elastic plastic metal material, such as an elastic metal plastic tile, can be used. Preferably, the inner wall of the mounting cavity and/or the outer wall of the slider 22 are provided with damping means to maintain the engaged position after movement in order to maintain the rolled or unrolled state of the display device. The connecting box 21 can be made of plastic, and has a light structure and low cost.
An embodiment of the present invention further provides a rollable display device, including: a crimpable mechanism, the crimpable mechanism comprising: the display unit 10 and the adjustable connection mechanism 20 are configured as described above with reference to fig. 1.
According to the technical scheme, errors such as production and assembly exist in the length of the composition structure of the rollable display device, automatic sliding adjustment can be achieved when a plurality of composition structures are rolled, and therefore the flexible screen can be rolled normally.
Further, the display unit 10 includes: a display screen 11 and a housing 12, the display screen 11 being mounted to the housing 12, the structure of which can be seen in fig. 5 and 8;
wherein the housing 12 is connected to the second end of the connector. As shown in fig. 6, the filling area is the display screen 11, the slanted stripe area is the housing 12, the slider 22 is connected to the housing 12 through the connecting rod 23, and the housing 12 serves as a mounting base for the display screen 11 to protect and realize movement.
In view of the problem that the outer ring is easy to be not rolled up during the rolling process. Thus, in this embodiment, the crimpable mechanism is capable of being crimped in a plurality of turns, with at least the second turn from inside to outside utilizing the adjustable attachment mechanism 20. That is, as shown in fig. 1, the connection mechanism at the innermost circle may be in a fixed distance form, and the non-adjustable connection mechanism does not need to be designed with extra length, so that the radial size after curling of the innermost circle can be prevented from being reduced, and the total radial size after curling of the whole rollable mechanism and the display device can be controlled.
The crimp circumferential error caused by the structure and operation is incremental with the number of turns, and therefore it is preferable to design the connection structure differently for different positions. Furthermore, at least two circles of the crimpable mechanism adopt the adjustable connecting mechanism 20, the maximum sliding distance of the adjustable connecting mechanism 20 at the outer circle is larger than that of the adjustable connecting mechanism 20 at the inner circle, and the gradual layer amplification of the crimping circumferential error can be met; the size increasing rule matched with the number of curling turns of the curling mechanism is set, so that the sliding range of the adjustable connecting mechanism 20 can be controlled conveniently, and the phenomenon that the overall radial size of the whole display device after curling is overlarge is avoided.
Preferably, the adjustable connecting mechanisms 20 are arranged on two sides of the plurality of display units 10, and the maximum sliding distance of the adjustable connecting mechanism 20 on the side of the display unit 10 far away from the curling center is greater than 1/20-1/15 of the maximum sliding distance of the adjustable connecting mechanism 20 on the side of the display unit 10 near the curling center. That is, the size of the adjustable connecting mechanism 20 in the present solution is gradually increased, and the rule is that the length of each section is greater than the length of the previous section by 1/20-1/15, so as to satisfy the gradual amplification of the curling circumferential error and avoid the overlarge total radial size of the whole display device after curling.
An embodiment of the present invention further provides an electronic device, including the rollable display device as described above.
As can be seen from the foregoing technical solutions, the electronic device provided in the embodiments of the present invention employs the rollable display device, so that all the beneficial effects described above are correspondingly achieved, and specific reference may be made to the foregoing description, which is not repeated herein.
In summary, the multiple unit structures (i.e. the display unit 10) included in the rollable mechanism according to the present disclosure further include a sliding structure (i.e. the adjustable connection mechanism 20) capable of being automatically adjusted, so that when there is an error in production and assembly, the rolling angle can be adjusted through the sliding structure, thereby preventing the flexible screen from being unable to be rolled normally due to the error in production and assembly. In addition, but automatically regulated's sliding structure in this scheme is owing to include the connecting box 21 of seting up guide way 24, and the ball-type slider 22 joint that passes through connecting rod 23 and connect at the both ends of display unit 20 units is in connecting box 21, and guide way 24 can make connecting rod 23 pass through, and then has errors such as production equipment in the length of every structure, can realize automatic slide regulation when curling a plurality of unit structures, and then makes the flexible screen normally curl.
