Through the above technical solution, that is, the display screen hinge mechanism provided in the first aspect of the present disclosure, the connecting seat 4 is pivotally connected to the supporting frame 3 by moving along the arc of the arc-shaped slot 301 through at least two supporting shafts 501, so that the display screen main body 1 is pivotally connected to the base 2, so that the display screen main body 1 and the base 2 are not rotationally connected through one hinge shaft or hinge point as in the existing hinge mode, but move along the arc-shaped slot 301 through at least two supporting shafts 501, and when supporting and rotating are performed, the connection between the display screen main body 1 and the base 2 is more stable, and the user experience is good; in addition, this disclosure can realize through drive unit the locking and the unblock of display screen main part 1 for base 2 to better promotion user experience effect. To sum up, the display screen hinge mechanism that this disclosure first aspect provided has solved the display screen and has easily taken place to rock, install unstable problem, can promote user experience effect simultaneously.

The locking refers to keeping the display screen main body 1 at a required unfolding angle relative to the base 2 when a user adjusts the display screen main body 1 and the base 2 to the required unfolding angle; the unlocking means unlocking the above-described locked state to allow adjustment of the deployment angle between the display screen main body 1 and the base 2.

In order to further increase the stability of the connecting base 4 when rotating relative to the supporting bracket 3, i.e. to increase the stability of the at least two supporting shafts 501 when moving along the arc of the arc-shaped slot 301, in some embodiments, as shown with reference to fig. 3 and 4, the at least two supporting shafts 501 are arranged spaced apart from each other along the arc of the arc-shaped slot 301. Thus, by increasing the distance between the support shafts 501 along the arcs, the rotation of the connecting base 4 relative to the supporting bracket 3 can be stabilized.

Considering that the frictional resistance between the support shafts 501 and the arc-shaped slots 301 is small when the unfolding angle between the display screen main body 1 and the base 2 is adjusted by the movement of the at least two support shafts 501 along the arc of the arc-shaped slots 301, it is not easy for the user to quickly adjust to the desired unfolding angle due to the strength of the user when adjusting the display screen main body 1. Therefore, in some embodiments, the display screen hinge mechanism includes a first guiding main body 6, the first guiding main body 6 is located below the supporting shaft 501, the surface facing the supporting shaft 501 is configured as an arc-shaped surface corresponding to the arc of the arc-shaped slot 301, the arc-shaped surface is provided with a first internal tooth 601, the supporting shaft 501 is coaxially sleeved with a third gear 7 capable of rotating around the axis of the supporting shaft, the third gear 7 is meshed with the first internal tooth 601, and the third gears 7 on two adjacent supporting shafts 501 are arranged at intervals. Therefore, by adding the third gear 7 and the first inner teeth 601 meshed with the third gear, damping can be provided for rotation of the display screen main body 1 in a gear meshing mode when the unfolding angle of the display screen main body 1 is adjusted, so that on one hand, a user feels better when rotating the display screen main body 1, the display screen main body 1 can be adjusted to a required unfolding angle more quickly, and the experience effect of the user is greatly improved; on the other hand, due to the existence of the damping, the stability of connection between the display screen main body 1 and the base 2 can be improved, so that the display screen is not easy to shake. Meanwhile, by adding the first guide body 6, the gravity from the display screen main body 1 can be shared with the support frame 3 to a certain extent, and the abrasion between the support shaft 501 and the arc-shaped slot hole 301 can be reduced. In addition, during production and manufacturing, the position of the first guide body 6 can be finely adjusted to adjust the fit clearance between the first internal teeth 601 and the third gear 7, so that the damping during the rotation of the display screen body 1 and the gravity from the display screen body 1 shared by the first guide body 6 can be further increased.

The surface of the first guiding main body 6 facing the supporting shaft 501 is configured as an arc-shaped surface corresponding to the arc of the arc-shaped slot 301, where corresponding means that the centers of the arc-shaped surface and the arc of the arc-shaped slot 301 are both located on the pivot axis of the display screen main body 1. Thus, the third gear 7 on the support shaft 501 can be ensured to be meshed with the first internal teeth 601 of the arc-shaped surface for transmission when moving along the arc of the arc-shaped slotted hole 301.

For example, in some embodiments, as shown with reference to fig. 3 and 4, the support shaft 501 is rotatably mounted to the connection holder 4 about its own axis. In this way, since the support shaft 501 can rotate about its axis, the third gear 7 can be fixedly connected to the support shaft 501 to follow the rotation of the support shaft 501. Of course, the third gear 7 may also be movably sleeved on the support shaft 501 and the support shaft 501 respectively rotate around their axes. Further, the support shaft 501 can be stopped by the first elastic retainer ring 502 to be axially limited on the connecting seat 4, and the installation and use mode of the elastic retainer ring are mature prior art and are not described again here.
