Specifically, the working principle of the synchronous module is as follows: when the inward folding terminal is unfolded to be closed, the left casing 52 rotates clockwise, the left bracket 11 is driven to rotate clockwise, the left casing rotating arm 25 is driven to rotate clockwise around the rotation center, the left casing rotating arm 25 drives the left rotating arm 26 to rotate clockwise through the connecting block, the left gear shaft 21 is driven to rotate clockwise, the right gear shaft 22 is driven to rotate anticlockwise through the transmission function of the middle gear set 24, the right rotating arm 29 is driven to rotate anticlockwise, the right casing rotating arm 28 is driven to rotate anticlockwise around the rotation center through the connecting block, and finally the right casing 53 is driven to rotate anticlockwise, so that the closing process of the inward folding terminal is realized. Similarly, when the inward folding terminal is in the process from closing to unfolding, the unfolding process is opposite to the movement direction of the closing process; the left casing 52 rotates anticlockwise, drives the left bracket 11 and the left casing rotating arm 25 to rotate anticlockwise, and drives the left rotating arm 26 and the left gear shaft 21 to rotate anticlockwise, so that the middle gear set 24 drives the right gear shaft 22 to rotate clockwise, and finally drives the right rotating arm 29, the right casing rotating arm 28, the right bracket 13 and the right casing 53 to rotate clockwise, thereby realizing the synchronous linkage function of the left casing 52 and the right casing 53.
The working principle of the locking module is as follows: when the inward folding terminal is opened to be closed, the left shell 52 and the right shell 53 rotate to be closed, the left shell rotating arm 25 and the right shell rotating arm 28 are driven to rotate around the respective rotation centers, the left shell rotating arm 25 and the right shell rotating arm 28 drive the left rotating arm 26 and the right rotating arm 29 to rotate through the connecting blocks, the left gear shaft 21 and the right gear shaft 22 are driven to synchronously rotate, and meanwhile the left concave-convex cam 33 and the right concave-convex wheel 34 are driven to rotate; when the left concave-convex cam 33 and the right concave-convex wheel 34 rotate from the slope bottom to the slope top of the cam seat 32, the left elastic piece 35 and the right elastic piece 36 are respectively compressed, so that locking handfeel is generated; when the left concave-convex wheel 33 and the right concave-convex wheel 34 are contacted with the top surface of the cam seat 32, the elastic piece is not continuously compressed at the moment, the spring force is unchanged, and the left gear shaft 21 and the right gear shaft 22 rotate stably; when the left concave-convex cam 33 and the right concave-convex wheel 34 rotate to the top of the convex slope of the cam seat 32, the left concave-convex cam 33 and the right concave-convex wheel 34 automatically move to the bottom of the slope under the action of spring force, so that the left gear shaft 21 and the right gear shaft 22 automatically rotate, and a locking hand feeling is generated to close the terminal equipment. Similarly, when the inward folding terminal is in the process of closing to unfolding, the working principle is opposite, and the unfolding action of the inward folding terminal is realized through the opposite movement directions.
The working principle of the screen supporting avoidance mechanism is as follows: when the inward folding terminal is unfolded to be closed, the left housing 52 and the right housing 53 rotate synchronously to drive the left bracket 11 and the right bracket 13 to rotate respectively, wherein the lifting blocks 121 of the left lifting plate 12 and the right lifting plate 14 slide downwards along the grooves 111a of the left bracket 11 and the right bracket 13 respectively, and the left lifting plate 12 and the right lifting plate 14 rotate along the respective rotation centers at the same time, so that the two side spaces are avoided to bend the screen. Similarly, when the inward folding terminal is opened from the closed state, the left housing 52 and the right housing 53 rotate synchronously to respectively drive the left bracket 11 and the right bracket 13 to rotate, wherein the lifting blocks 121 of the left lifting plate 12 and the right lifting plate 14 slide upwards along the grooves 111a of the left bracket 11 and the right bracket 13 respectively, thereby promoting the upward supporting of the screen by the left lifting plate 12 and the right lifting plate 14, finally realizing the functions of avoiding and supporting the screen space, and preventing the screen from generating folds and bulges.
The internal folding hinge has small space occupation ratio, simple and efficient action mechanism, can meet the requirement of any three-section folding mobile terminal, solves the technical problem that the containing space of the existing closed drop-shaped flexible screen is insufficient, and can prevent the screen from generating folds and bulges.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
