in addition, when the connecting plate 35 drives the turning rod 314 to move upwards to automatically turn over the other side of the folding screen mobile phone, the connecting plate 35 drives the wave plate 310 to move upwards, so that the wave structure of the wave plate 310 penetrates through the wheel disc b32 and gradually leaks out, and the leaked part and the impact rod 39 are extruded, so that the extrusion degree of the impact rod 39 and the wave plate 310 can be automatically adjusted according to the turning angle of the other side of the folding screen mobile phone, and the vibration amplitude of the wheel disc a31 is changed; the folding screen mobile phone has the advantages that the folding screen mobile phone is also changed under the influence of gravity due to the different overturning angles, the unfolding hovering state is detected by automatically changing the vibration amplitude according to the overturning angles, the automation and the intellectualization are improved, the design for automatically adjusting the vibration amplitude according to the overturning angles is more ingenious, the connection between the overturning angles and the vibration amplitude can be formed, and the detection effect is improved;
when the inner shaft 36 rotates, the ratchet 38 moves upwards and drives the sleeve 48 to move, the inner shaft 36 drives the screw rod 42 to rotate, and the outer tube 45 is fixedly arranged on the bearing seat 43 because the screw rod 42 is connected with the bearing seat 43 through the ball nut pair and the outer tube 45 only can slide up and down on the screw rod 42, so that when the screw rod 42 rotates, the bearing seat 43 drives the outer tube 45 to move upwards along the screw rod 42 and the outer tube 45 drives the sleeve 46 to move through the telescopic spring 47; when the inner shaft 36 starts to rotate reversely, the bearing seat 43 moves downwards along the screw rod 42, the bearing seat 43 drives the sleeve 46 to move through the outer tube 45, the sleeve 46 drives the extrusion rod 44 to move, in the process that one end of the extrusion rod 44 contacts with the other side of the folding screen mobile phone, the impact rod 39 is extruded with the wave plate 310 to complete vibration detection, then one end of the extrusion rod 44 contacts with the other side of the folding screen mobile phone to extrude the extrusion rod 44, the extrusion rod 44 extrudes the telescopic spring 47, so that the thrust detection of the other side of the folding screen mobile phone can be completed, the wheel disc a31 drives the non-contact force vibration detection of the vibration of the other side of the folding screen mobile phone, the detection of the other side of the folding screen mobile phone is more flexible, the pressure detection of the other side of the folding screen mobile phone is completed for one accurate force, and the hinge virtual position quality of the folding screen mobile phone can be more accurately detected by using the pressure detection of two different modes;
in addition, according to the continuous upward movement of the ratchet 38, the ratchet 38 continuously drives the sleeve 48 to move upward, when the outer tube 45 drives the sleeve 46 to move downward, one end of the sleeve 46 is inserted into the sleeve 48 to increase the internal pressure, because the internal pressure of the sleeve 48 is increased, the sleeve 46 can only move up and down on the outer tube 45, and the sleeve 46 presses the telescopic spring 47, because the distance of each downward movement of the outer tube 45 is fixed, however, when the ratchet 38 continuously moves upward, the sleeve 46 is caused to move downward, the pressure inside the sleeve 48 is gradually increased, and then the sleeve 46 is pressed by the internal pressure of the sleeve 48 to gradually increase the distance of the sleeve 46 moving on the outer tube 45, so that the distance of the sleeve 46 driving the pressing rod 44 to move downward is gradually reduced, on the one hand, the other side of the folding screen mobile phone continuously overturns to increase the height, so that the contact time between the pressing rod 44 and the other side of the folding screen mobile phone is prevented from being too early, the detection work is influenced, and on the other hand, the moving distance of the pressing rod 44 is changed, the elastic force of the telescopic spring 47 is gradually increased, the elastic force of the pressing rod 44 and the other side of the folding screen mobile phone is changed, the automatic turnover angle is automatically detected, the automatic turnover force is greatly changed, and the extrusion force is greatly changed, and the automatic extrusion force is detected.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
