Embodiment
The utility model embodiment aims to provide a kind of portable terminal and slip lid opening and closing detector thereof, and the slip lid opening and closing detector of described portable terminal is more accurate to the testing result of portable terminal slip lid folding condition.
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
As shown in Figure 1, a specific embodiment for the utility model portable terminal, in the present embodiment, described portable terminal comprises main frame portion 1 and sliding lid part 2, in main frame portion 1, be provided with portable terminal slip lid opening and closing detector, described portable terminal slip lid opening and closing detector comprises mechanical switch 3, and mechanical switch 3 is located at the side edge of main frame portion 1.As shown in Figure 2, mechanical switch 3 has insulation crust 31, has been installed with electroconductive elastic sheet 32 in insulation crust 31.As shown in Figure 3, electrical block diagram for slip lid opening and closing detector in the portable terminal shown in Figure 1, in this slip lid opening and closing detector, mechanical switch 3 one ends and test section 4 electrically connect, the other end and ground wire 5 electrically connect, mechanical switch 3 closed or open and to make test section 4 be communicated with or disconnect with ground wire 5, test section 4 is communicated with the back and obtains low level with ground wire 5, test section 4 disconnects the back with ground wire 5 and obtains high level, test section 4 is just determined the folding condition of the sliding lid part 2 of described portable terminal according to the height of its level that obtains, there is not magnetic interference in this portable terminal slip lid opening and closing detector, and its testing result is more accurate.
Wherein, from the above, described mechanical switch 3 comprises the electroconductive elastic sheet 32 that is located in the insulation crust 31.As shown in Figure 4, electroconductive elastic sheet 32 comprises moving contact 33 and the fixed contact 34 that is used with moving contact 33.And as can be seen from Figure 3, moving contact 33 passes insulation crust 31 and is electrical connected with test section 4, and fixed contact 34 passes insulation crust 31 and is electrical connected with ground wire 5.Depress moving contact 33, then moving contact 33 and fixed contact 34 closures, thus make test section 4 and ground wire 5 be connected, and make test section 4 obtain low levels; Unclamp moving contact 33, then moving contact 33 is opened with fixed contact 44, thereby makes test section 4 disconnect mutually with ground wire 5, and makes test section 4 obtain high level.
In order to depress or unclamp described moving contact 33, in the present embodiment, mechanical switch 3 is located on the mobile route of sliding lid part 2, the user promotes that sliding lid part 2 is opened or is closed, sliding lid part 2 open motion closing motion can be depressed or release mechanism switch 3 in moving contact 33, thereby test section 4 be communicated with ground wire 5 or disconnect.
Particularly, be that mechanical switch 3 is located in the main frame portion 1, and as shown in Figure 5, on the side of sliding lid part 2 and with mechanical switch 3 corresponding positions, projection 21 be set that projection 21 is used for depressing moving contact 33 after sliding lid part 2 closures.Its process is as follows: slide in the closed process in sliding lid part 2, projection 21 is gradually near mechanical switch 3, when the projection 21 move in the mechanical switch 3 electroconductive elastic sheet 32 tops the time, electroconductive elastic sheet 32 is subjected to the external force effect and deforms, this moment, moving contact 33 was depressed, moving contact 33 and fixed contact 34 closures afterwards, thereby test section 4 is connected test section 4 acquisition low levels with ground wire 5; Otherwise, in the process that sliding lid part 2 slips off, projection 21 breaks away from mechanical switch 3 gradually, when the projection 21 break away from fully in the mechanical switch 3 electroconductive elastic sheet 32 time, electroconductive elastic sheet 32 is eliminated because of external force and is recovered deformation, and this moment, moving contact 33 was released, and moving contact 33 is opened with fixed contact 34 afterwards, thereby test section 4 disconnects test section 4 acquisition high level mutually with ground wire 5.
In the present embodiment, the software judgment mechanism of test section 4 inside is set at: test section 4 obtains low level and then determines sliding lid part 2 closures; Test section 4 obtains the then definite sliding lid part 2 of high level and opens.Therefore, the inspection sidepiece 4 in the present embodiment can be used in the folding condition of determining sliding lid part 2 according to the state of mechanical switch 3.
And in the present embodiment, test section 4 is the CPU of described portable terminal inside, this CPU has GPIO mouth (General Purpose Input Output, general input/output interface), and the moving contact 33 of mechanical switch 3 just link and be connected on the GPIO mouth of this CPU.Use this CPU as the test section in the described portable terminal, just do not need to be separately more described slip lid opening and closing detector outfit relevant detection parts, thereby can simplify the hardware setting of described portable terminal slip lid opening and closing detector.
As shown in Figure 6,, in described portable terminal, also be provided with control part 6, and test section 4 electrically connects with control part 6 as a kind of improvement to present embodiment.Wherein, test section 4 has been determined the folding condition of sliding lid part 2 according to the state of mechanical switch 3, and the folding condition of sliding lid part 2 is generated detection signal, then this detection signal is passed to control part 6, the controlling mechanism of control part 6 inside selects portable terminal to enter standby mode or power on mode according to detection signal.And control part 6 also is the CPU of described portable terminal inside, and promptly described CPU has the function of test section 4 and control part 6 simultaneously.
In like manner, in other embodiment of the present utility model, described mechanical switch can be located on the described sliding lid part, and on the side of described main frame portion and with the corresponding position of described mechanical switch, projection be set, described projection is used for depressing described moving contact after described sliding lid part closure.Its process is: after described sliding lid part slided closure, described projection was depressed described moving contact, made described moving contact and described fixed contact closure, thereby described test section is connected with described ground wire, and described test section obtains low level; Otherwise after described sliding lid part sliped off, described projection broke away from described moving contact, and described moving contact is released, makes described moving contact and described fixed contact open, thereby described test section disconnects described test section acquisition high level mutually with described ground wire.At this moment, the software judgment mechanism of described test section inside is set at equally: described test section obtains low level and then determines described sliding lid part closure; Described test section obtains the then definite described sliding lid part of high level and opens.
Has portable terminal slip lid opening and closing detector in the portable terminal that the utility model embodiment provides, described portable terminal slip lid opening and closing detector comprises mechanical switch and test section, described test section can be determined the folding condition of portable terminal slip lid according to the state of described mechanical switch, there are not problems such as magnetic interference in this checkout gear, and its testing result is more accurate.
The 26S Proteasome Structure and Function of the described portable terminal in another specific embodiment of the utility model portable terminal, the 26S Proteasome Structure and Function of the described portable terminal in the present embodiment and the foregoing description is substantially the same, and its difference only is described sliding lid part.
