Abstract
The utility model relates to an anti-theft device for cell phones, which comprises an electromagnetic on and off circuit and a sliding device, wherein in the electromagnetic on and off circuit, a loop is composed of an electromagnetic induction coil and a cell phone PCB board power supply. A magnetic body with opposite magnetic polarities on opposite directional surfaces is arranged in a position corresponding to the electromagnetic induction coil, and the sliding device is composed of a sliding block on which a spring is sheathed. One end of the sliding block is fixed with the magnetic body. The other end of the sliding block forms an oblique angle, which is convenient for buckling a battery. The utility model makes use of the existing cipher identification technique, so if users can not input correct ciphers, the users can not open the battery. Then, an SIM card can not be taken out. The utility model plays the anti-theft role, and has the advantages of simple circuit and simple and practical mechanism design.
Description
[technical field]
The utility model relates to a kind of anti-stealing device for handset, specifically is the anti-theft device that encryption recognition system is combined with phone housing mechanism.
[background technology]
Frequent generation though mobile phone is easy to carry, has also produced the problem of losing easily along with the increasing of cellphone subscriber in view of the situation of present hand-set from stolen, has an opportunity to take advantage of to the lawless person especially easily.Application number is 02286626.3, the applying date is 2002.12.09, the Chinese utility model patent that name is called " anti-stealing device for handset " discloses a kind of anti-stealing device for handset, this device comprises the warning circuit that is placed in the cell-phone cover, at bit switch, also comprise cipher switch, can when taking place to steal, report to the police, play antitheft effect.Yet this anti-theft device is arranged on the device outside the mobile phone to reach antitheft purpose, has limited when the user must use mobile phone and cell-phone cover jointly just can reach antitheft purpose, is unfavorable for general development.
[summary of the invention]
The purpose of this utility model is to improve the deficiencies in the prior art, and a kind of anti-stealing device for handset that combines with encryption recognition system is provided.
Anti-stealing device for handset of the present utility model comprises the electromagnetism on-off circuit that is placed in the hand set machine shell, device slidably, wherein the electromagnetism on-off circuit constitutes the loop by electromagnetic induction coil and mobile phone pcb board power supply, with the corresponding position of described electromagnetic induction coil, the opposite magnet of forward surface magnetic polarity is arranged, described slidably the device by the slide block that is socketed with the spring string on it formed, one end and the magnet of slide block are fixed, and the other end is designed to be convenient to the assembling inclined-plane that battery buckles into.When the electromagnetism on-off circuit did not have conducting, the spring string was in relaxed state, and the slide block other end blocks battery cover, and be lock-out state this moment.When the conducting of electromagnetism on-off circuit, under the electromagnetic field effect that there is a natural attraction between the sexes, this permanent magnet drives slide block and moves, and the spring string is in extended state, and this moment, battery can easily take out.The user only need input correct password, and has passed through password validation system, controls the break-make of electromagnetic circuit, reaches the purpose of control battery folding.
The beneficial effect of the utility model anti-stealing device for handset is: utilize existing password identification technology, if the user can not input correct password, then can not open battery, and then just can not take out SIM card, play antitheft effect, its circuit is simple and direct, and mechanism design is simple and practical.

[embodiment]
Provide embodiments of the invention below in conjunction with accompanying drawing, anti-stealing device for handset of the present utility model comprises electromagnetism on-off circuit A, constitutes the loop by electromagnetic induction coil 2 and pcb board power supply, and magnet 1 adopts permanent magnet to replace spring string 3, pcb board 4, slide block 5, battery 6.
As shown in Figure 1, electromagnetic induction coil 2 is corresponding with permanent magnet 1 position among the electromagnetism on-off circuit A, and the two shape size is identical, the magnetic polarity of forward surface is opposite, wherein electromagnetic induction coil 2 is fixed on the casing, permanent magnet 1 is fixing with slide block 5, be socketed with spring string 3 on the slide block 5, and permanent magnet 1 is against an end that is fixed on spring string 3, the other end of spring string 3 is fixed, and when slide block 5 was in position shown in Figure 1, the spring string was in relaxed state, when slide block 5 was in position shown in Figure 2, the spring string was in extended state.When the user imports proper password, the stitch of chip for cell phone is exported corresponding level signal, pcb board 4 received signals, conducting electromagnetism on-off circuit A, carry electric current to electromagnetic induction coil 2, electromagnetism on-off circuit A and permanent magnet 1 produce the magnetic field that there is a natural attraction between the sexes, permanent magnet 1 drives slide block 5 and slides left automatically, to the position shown in Fig. 2, drive spring string 3 simultaneously and stretch, just can conveniently take out battery 6 this moment, when not having electric current to pass through between the electromagnetism on-off circuit A, this moment, slide block 5 automatically reverted to position shown in Figure 1 again under the effect of spring string 3.If the user need be installed to battery on the mobile phone again, because the other end of slide block 5 is designed to be convenient to the assembling inclined-plane that battery buckles into, only need a little firmly just slide block 5 to be promoted left, battery 6 is packed into, then under the effect of spring string 3, slide block 5 is returned to Fig. 1 position again, with battery 6 lockings.When input password mistake, electromagnetism on-off circuit A does not have conducting, so permanent magnet 1 can not move, and slide block 5 is in state among Fig. 1, and slide block 5 can't be moved to the left, and this moment, battery was in the lock state.
Magnet 1 can also be replaced by another electromagnetism on-off circuit B in the utility model, constitute the loop by electromagnetic induction coil and pcb board power supply equally, as shown in Figure 3, when the user imports proper password, the stitch of chip for cell phone is exported corresponding level signal, pcb board 4 received signals, conducting electromagnetism on-off circuit A, B, because the current direction of two electromagnetism on-off circuits is opposite, therefore under the electromagnetic field effect that there is a natural attraction between the sexes, also can drives slide block 5 and move.
Be understood that, when owner uses mobile phone, as long as inputed correct password, just can easy and conveniently must take out battery, if mobile phone stolen by other people because do not know proper password, just can't open battery, thereby can not obtain the replacing SIM card, so just play antitheft purpose.And the password identification technology also can satisfy owner's use needs by the setting of prior password setting and input number of times.
In addition to the implementation, the utility model can also be taked other execution modes, for example can adopt other modes to substitute the electromagnetism on-off circuit, as long as after having imported proper password, thereby the taking-up battery that moves of may command slide block gets final product.
