right gear shaft13, the cam surface generates a climbing action and a descending action under the action of the elastic force of the second
elastic piece21, and finally a locking hand feeling is formed.
In the present embodiment, the first
elastic member16 and the second
elastic member21 are springs, and it should be understood that in other embodiments, the first elastic member and the second elastic member may be other elastic mechanisms such as elastic sheets and disc springs, which can provide good elastic force.

rotatory piece3 and rotates jointly, and
left casing25 follows
left slide rail7 and rotates jointly, and
right casing26 follows
right slide rail8 and rotates jointly. The rotating mechanism, the synchronizing mechanism, the supporting structure and the space avoiding mechanism are combined together to form a linkage module for realizing linkage action of the left cover plate, the right cover plate, the left shell and the right shell.
Furthermore, the two sides of the
slide rail seat1 are provided with hollow parts, the hollow parts are provided with slide rails arranged in an arc shape, the slide rails are matched with the arc-shaped slide grooves, and the rotation action of the left rotating block and the right rotating block is realized through the arrangement of the arc-shaped slide rails.
Specifically, the working principle of the synchronizing mechanism is as follows: when the hinge is opened to be closed, the
left shell25 rotates clockwise under the action of external force, so that the left sliding
rail7, the left cam seat 5 and the
left gear shaft12 are driven to rotate clockwise, the
right gear shaft13, the
right cam seat6 and the right sliding
rail8 are driven to rotate anticlockwise through the rotation of the
intermediate gear14, and the synchronous motion of closing the hinge is realized. Similarly, when the hinge is unfolded from the closed state, the
left shell25 rotates counterclockwise to drive the
left slide rail7, the left cam seat 5 and the
left gear shaft12 to rotate counterclockwise, and the
middle gear14 rotates to drive the
right gear shaft13, the
right cam seat6 and the
right slide rail8 to move clockwise, so that the synchronous motion of the hinge in the unfolding process is realized.
Specifically, the working principle of the locking mechanism is as follows: when the cam is opened to be closed, the cam surfaces of the left cam seat 5 and the
right cam seat6 rotate, so as to jack up the
cam clamping seat22 and compress the second
elastic piece21; when the left cam seat 5 and the
right cam seat6 rotate to a certain angle and the cam surfaces of the left cam seat 5 and the
right cam seat6 are positioned at the top of the slope of the
cam card seat22, the left cam seat 5 and the
right cam seat6 push against the
cam card seat22 under the action of elastic force to realize automatic rotation, and finally, the closing and locking effects are realized; similarly, when the cam surfaces of the left cam seat 5 and the
right cam seat6 rotate to a certain angle in the process from closing to opening, the
cam seat22 is pushed to automatically rotate under the action of the elastic force of the second
elastic element21, and finally the opening locking function is realized.
Specifically, the working principle of the space avoiding mechanism and the supporting structure is as follows: in the process from unfolding to closing, because the rotating centers of the left rotating
block2, the right rotating
block3, the left cam seat 5 and the
right cam seat6 are different, and the rotating centers of the left cam seat 5 and the
right cam seat6 are close to the outer side, the rotating centers of the left rotating
block2 and the right rotating
block3 are close to the inner side; when the screen is completely rotated and closed, the left cam seat 5 and the
right cam seat6 are close to the outer side, the left sliding
rail7 and the right sliding
rail8 can slide relatively, and the left rotating
block2 and the right rotating
block3 are close to the inner side, so that the inner space is given out, and the screen space avoiding action is realized. Meanwhile, when the gear rack is in an unfolded state, the
middle cover plate15 is locked on hole positions of hole grooves of the lower gear seat and the support frame, the first
elastic piece16 is in a compressed state, the
middle cover plate15 is urged to be pulled downwards by the first elastic piece, and the
middle cover plate15 is supported by the
gasket19 to be attached to the gasket and not move; when the rotating shaft starts to close, the
gasket19 rotates along with the
left gear shaft12 and the
right gear shaft13, at the moment, the
gasket19 no longer supports the
middle cover plate15, and then the
middle cover plate15 moves downwards under the action of the first
elastic piece16 to enable the upper space to bend the screen, so that the screen is avoided. Similarly, when the screen is opened by closing, the
gasket19 rotates along with the left gear shaft and the right gear shaft, and then abuts against and supports the middle cover plate, so that the screen supporting function is realized.
The folding hinge in the mobile terminal has the functions of screen support and screen avoidance, is small in space occupation ratio, simple and efficient in action mechanism, effectively simplifies the structural complexity of the hinge, and is suitable for three-section type folding mobile terminals.
