Embodiment
Please refer to Fig. 1, it is the calcspar of storage card protection function that a kind of electronic installation of preferred embodiment of the present invention is shown.The electronic installation 100 of present embodiment can be mobile phone, personal digital assistant, intelligent mobile phone or portable multimedia play device.Electronic installation 100 comprises body 110, cover plate 120, electronic switch 130, input interface 140 and control unit 150.Please be simultaneously with reference to Fig. 2, the closed condition schematic diagram of the cover plate of a kind of electronic installation of preferred embodiment of the present invention shown in it.Body 110 stores a preset password and has an electrical slot 112, for example is a memory bank, but cover plate 120 is arranged on the body 110 in the mode of folding.When cover plate 120 in off position the time, cover plate 120 covers electrical slot 112.Electronic switch 130 is to be arranged on the body 110 with locking or release cover plate 120.When cover plate 120 was closed, electronic switch 130 was at electronic installation 100 power-on time locking cover plate 120 not.
As shown in Figure 2, cover plate 120 also has one first junction surface 122, and electronic switch 130 also comprises a locked assembly 132 and an electromagnetic assembly 134.Locked assembly 132 slidably is arranged in the body 110, and locked assembly 132 has one first end and one second end, and first end has one second junction surface 132a.When first junction surface 122 and the second junction surface 132a interfere, cover plate 120 and body 110 lockings.Electromagnetic assembly 134 is arranged on the body 110.
Locked assembly 132 also has a projection 132b and a latch 132c, and latch 132c is connected with projection 132b.Second end of locked assembly 132 is positioned on the latch 132c, and first end of locked assembly 132 then is positioned on the opposite side of projection 132b with respect to latch 132c.In the present embodiment, comprise that more preferably an elastic parts 133 is inserted in latch 132c, a baffle plate 135 is fixedly arranged on the body 110.Latch 132c inserts baffle plate 135 and can move with respect to baffle plate 135, and elastic parts 133 is a spring for example, is between baffle plate 135 and projection 132b.
In the present embodiment, first junction surface 122 has a draw-in groove, and the second junction surface 132a has a protuberance, makes first junction surface 122 and the second junction surface 132a can produce interference effect.Wherein, protuberance also can preferably be designed to have the fillet of leading, and cover plate 120 is pressed down and leads fillet when contacting, and can produce a transverse component to the second junction surface 132a, projection 132b is shunk back backward, and elastic parts 133 props up baffle plate 135 and the corresponding elastic stress that produces.When the protuberance of the second junction surface 132a arrived the draw-in groove at first junction surface 122, the elastic stress that elastic parts 133 is produced pushed protuberance in the draw-in groove, made cover plate 120 fixing with body 110.But the invention is not restricted to this, also can be that first junction surface 122 has a protuberance, and the second junction surface 134a then has a draw-in groove.
Please refer to Fig. 3, it is the opening schematic diagram of cover plate of a kind of electronic installation of preferred embodiment of the present invention.When electromagnetic assembly 134 conductings, can produce second end of a magnetic attraction because of electromagnetic action with absorption and mobile locked assembly 132, just attract latch 132c that first junction surface 122 and the second junction surface 132a are separated to open cover plate 120.Latch 132c is a magnetisable material, for example iron or nickel etc.In the present embodiment, the structure that latch 132c and projection 132b preferably are formed in one.Because an end of cover plate 120 is to be articulated in body 110, one torsion springs 116 contiguous these ends with articulated section 114 to be arranged on the body 110.When electronic switch 130 is opened, cover plate 120 is opened with respect to body 110 by the elastic force of torsion spring 116.
The electronic installation that the above embodiment of the present invention disclosed is the mode that cooperates the password input with electronic switch, designs suitable protection mechanism and stores card with protection.Because active force is an electromagnetic force, must could import password under power opening state protective device is opened, and can guarantee to store the safety of card.
Though the present invention discloses as above with reasonable embodiment; yet it is not in order to limit the present invention; the people who has common knowledge in the technical field under any; without departing from the spirit and scope of the present invention; can do all change that is equal to and retouching, so protection scope of the present invention should be with being as the criterion that claim was defined.
