In the above-described embodiments, described portable terminal can be mobile phone, panel computer, but is not only mobile phone and panel computer, can also be other portable terminal.
The motion process of portable terminal of the present utility model is as follows:
Be illustrated in figure 8 as the utility model opening procedure schematic diagram, the movement locus of the process that the utility model is opened is circular arc.In initial condition, the angle of tooth bar and first rotating parts is an acute angle X.Giving loam cake a horizontal force F, the component that is subjected to for first rotating parts and second rotating parts is F1, F2.Analyze first rotating parts this moment: because under power F1 effect, rotating panel produces moment: thus F1cosX has realized the realization of whole utility model mechanism kinematic.
When the utility model is in closure state, rotating panel initial conditions and horizontal direction angle are acute angle X degree, promote loam cake, give the effect of loam cake one power, because loam cake is fixedlyed connected with an end of first rotating parts, second rotating parts, and the other end of first rotating parts and second rotating parts is connected with the lower cover gear is coaxial, drives the loam cake Unscrew thereby make first rotating parts and second rotating parts produce turning moment under horizontal force action; In opening procedure, because an end and the gear of first rotating parts and second rotating parts are coaxial, driven gear rotates in first rotating parts and the second rotating parts rotating process, because gear and tooth bar engagement fit, gear rotates and drives the tooth bar horizontal motion.And an end of tooth bar is connected with spring, and spring one end is fixed in lower cover, tooth bar horizontal movement compression spring; Move to certain distance at loam cake, tooth bar moves horizontally extrusion spring makes spring reach the edge that moves to horizontal concrete chute after the maximum compressibility at the drop-down carry-over bar of the effect of spring restoring force fully, because the motion of tooth bar has driven an end of gear and coaxial rotating parts and has rotated, therefore the other end of rotating parts will be the center of circle with rotating parts and gear on-axis point, rotating parts two axle center distance degree are radius, drive upper cover plate and finish the complete Unscrew of loam cake, thereby realized the semi-automatic opening of loam cake.
When the utility model need be closed, give loam cake and under keyboard lid horizontal force action, promote the loam cake motion, loam cake driven rotary parts rotate, and rotating parts and lower cover link driven gear rotate, and gear driven tooth bar extension spring.Promoting certain distance at loam cake makes spring reach maximum compressibility, the motion of spring restoring force pulling tooth bar, one end of tooth bar motion driven gear and coaxial rotating parts rotates, one end of rotating parts rotates and drives the loam cake rotation of fixedlying connected with the rotating parts other end, and the semi-automatic of loam cake closed in realization.
The closing course characteristics of motion is consistent with unfolding mode, and only direction is opposite.In whole motion process, first module and intermediate module are to move in the horizontal direction all the time, can not produce difference in height or rock, motion steadily, feel is better.
The motion of mobile terminals that the utility model provides is steady, and is easy to operate, and good hand touch can not produce and rock, but the operating area of keyboard is bigger, and whole project organization thinner thickness and rotating mechanism can form good the connection with portable terminal.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
