Taking the first connecting piece 2 as an example: in the process of unfolding and folding the two fixing plates 100, the clamping pins 710 on the first connecting piece 2 outwards push against the limiting block 71, so that the springs are compressed to generate a force pressing against the limiting block 71, and the limiting block 71 presses against the first connecting piece 2, so that when the external force disappears, the fixing plates 100 can hover at a certain position. The second connector 3 is identical in structure and assembly to the first connector 2 and will not be described in detail.
The open-close structure 200 is schematically shown in the unfolded state in fig. 14, and is schematically shown in the closed state in fig. 15 and 16; the slider 4 is moved in the direction of the arrow in fig. 14 during the process from the unfolded state to the closed state, and similarly, the slider 4 is moved in the direction opposite to the arrow during the process from the folded state to the unfolded state. The slider 4 reciprocates along the mount 1 during opening and closing.
It should be noted that, the mobile terminal mentioned in this embodiment includes, but is not limited to, a mobile phone, a tablet computer, and the like.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
