Embodiment
Referring to figs. 1 through Fig. 4, the structure of the automatic turn-on device of turning-lid mobile communication terminal that utilizes electromagnet of one embodiment of the invention is described, Fig. 1 is the accompanying drawing that shows the electromagnet of installing in the hinged-lid mobile communication terminal of one embodiment of the invention, Fig. 2 is the accompanying drawing that shows the principle of electromagnet shown in Figure 1, Fig. 3 is the accompanying drawing that shows the hinge of installing in the hinged-lid mobile communication terminal, and Fig. 4 is the oblique view of stationary cam shown in Figure 3.
As shown in Figures 1 to 4, utilize the automatic turn-on device of turning-lid mobile communication terminal of electromagnet to comprise electromagnet 10 and 10`, guide portion 20 and 20`) and hinge 30.
Electromagnet 10 and 10` are installed on fuselage 1 respectively and renovate 5 opposite position, and one end and fuselage 1 and renovate 5 shell and combine closely or expose a part, the other end are installed on respectively in the through slot 7 and 7` on printed circuit board (PCB) 3 and the 3`.
Electromagnet 10 and 10` receive the signal from control part (not marking among the figure), N or S polarity occur, at this moment, if the polarity of relative electromagnet 10 and 10` is identical, phase repulsive interaction (as shown in Figure 2) take place then, make to renovate 5 and open to arbitrarily angled from fuselage 1.
The intensity of this electromagnet is as follows according to the Coulomb's law performance.
F = K m 1 * m 2 r 2 [ N ]
Suppose m=m 1=m 2, required power, the r=2.5mm of F=50 (N)=renovate rotation,
M=4.74*10 so -7Wb,
So, if electromagnet intensity is greater than 4.74*10 -7Wb then can open and renovate.
Guide portion 20 and 20` make the end of above-mentioned electromagnet 10 and 10` be fixed in fuselage 1 and renovate on printed circuit board (PCB) built-in in 53 and the 3`, and the other end of electromagnet 10 and 10` then is adjacent to or is exposed to fuselage 1 and renovates 5 shells.
Driving cam 32 is built in renovates central authorities, and stationary cam 34 is built in the hinge arm of fuselage, and along with the rotation of renovating 5, driving cam 32 rotates with stationary cam 34.
One side of stationary cam 34 is circumferentially formed concave surface and convex surface, and a side of above-mentioned concave surface and convex surface slowly tilts, and the another side then sharply tilts.
Therefore, driving cam 32 is along the rapid inclined plane of stationary cam 34, utilize the repulsion of electromagnet 10 and 10` turn to automatically arbitrarily angled after, under the effect of the elastic force of renovating the inertia opened along slow inclined plane and the inner elastic component that is had, rotate automatically, at this moment, above-mentioned arbitrarily angled preferably 30 °, it is also rotatable that axostylus axostyle 36 is combined on the same axle driving cam 32 and stationary cam 34, elastic component 38 is built between the housing and driving cam 32 of hinge 30, makes driving cam 32 be adjacent to stationary cam 34 and rotatable.
Below with reference to Fig. 1 to Fig. 4, the action of the automatic turn-on device of turning-lid mobile communication terminal that utilizes electromagnet of one embodiment of the invention is described.
At first, for open automatically renovate 5 press opening signal is provided open key (not marking among the figure).At this moment, as opening key, the side switch that can use the mobile communication terminal side to have also can use other key.
Press open key (not marking among the figure) after, opening signal is provided for control part (not marking among the figure), control part to the signal that electromagnet 10 and 10` provide polarity, is controlled the driving of electromagnet 10 and 10` with this according to opening signal.
The signal that provides according to control part (not marking among the figure), be installed on fuselage 1 respectively and be endowed identical polar with the electromagnet 10 and the 10` that renovate 5 relative positions, produce the phase repulsive interaction, under the repulsion effect of electromagnet 10 and 10`, renovate 5 and open to arbitrarily angled from fuselage 1.
From above-mentioned arbitrarily angled after, according to the structure of hinge 30, under the effect of the elastic force of renovating the elastic component that the inertia opened and inside had, renovate automatic fully-open.
The present invention can be implemented with other concrete form under the prerequisite that does not change its technological thought and essential feature, and this is that the practitioner of the technical field of the invention is understandable.Therefore, the embodiment of above-mentioned record is interpreted as just the example of all aspects is not limited only to this.
