Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of portable terminal with protective device, and the protective device of this terminal comprises: shell, lid, CPU 21, testing circuit 22, power supply circuits 23 and data card base.
Wherein, CPU 21, testing circuit 22, power supply circuits 23 and data card base are positioned at shell; Lid is connected with shell, and this lid comprises link; CPU 21 links to each other with power supply circuits 23 with testing circuit 22.CPU 21, testing circuit 22 and power supply circuits 23 constitute a protective circuit, as shown in Figure 2.
With reference to the structural representation of protective circuit among Fig. 2, testing circuit 22 comprises two incorgruous metal clipss: 222, two incorgruous metal clipss of first incorgruous metal clips 221, the second incorgruous metal clips are staggered relatively, constitute a rubber-like clip; Testing circuit 22 also comprises resistance 223, and first end of resistance 223 links to each other with the first incorgruous metal clips 221 with CPU 21 respectively, the second termination high level of resistance 223; The second incorgruous metal clips 222 connects public ground.When lid is closed, link on the lid is inserted between the first incorgruous metal clips 221 and the second incorgruous metal clips 222, the second incorgruous metal clips 222 connects public ground, the first incorgruous metal clips 221 is gone into high level by first termination of resistance 223, this moment testing circuit 22 to produce first level signal be high level, CPU 21 be that data card on the data card base is powered according to detected described first level signal control power supply circuits 23; When the link on the lid breaks away from described two incorgruous metal clipss, the first incorgruous metal clips 221 and the second incorgruous metal clips 222 contact with each other, then the first incorgruous metal clips 241 connects public ground by the second incorgruous metal clips 242, testing circuit 22 generations this moment second level signal is a low level, and CPU 21 is according to 23 outages of detected described second level signal control power supply circuits.
In addition, power supply circuits 23 comprise that also triode 231, the first pins 2311 link to each other with CPU 21, and second pin 2312 connects power supply, and the 3rd pin 2313 links to each other with data card base.
By the portable terminal that the utility model provides with protective device, can prevent the storage medium warm swap in the terminal, effectively prevent warm swap infringement storage medium and loss of data; In addition, the circuit design of protective device is simple and reliable, is user-friendly to.
Fig. 3 is the structural representation in the utility model the is applied in concrete enforcement environment.As shown in Figure 3, an end of lid 1 is fixed on the product casing 2 by a connecting axle, and this connecting axle can make lid 1 rotating certain angle, with the action of finishing lid 1 closure and opening.A salient point 4 is arranged on the lid 1, and this salient point 4 is made by megohmite insulant.Metal clips 5 is fixed on the pcb board.When lid 1 closure, salient point 4 inserts between metal clipss 51 (as the first incorgruous metal clips 241 among Fig. 2) and the metal clips 52 (as the second incorgruous metal clips 242 among Fig. 2), and metal clips 51 and metal clips 52 are separately; When lid 1 was opened, salient point 4 breaks away from metal clips 51 and 52, two metal clipss of metal clips contact with each other.SD/SIM card base 3 is fixed on PCB (Print Circuit Board, the printed circuit board (PCB)) plate.
Cause damage in order to prevent before outage plug SD/SIM card, on the pcb board of the protective device that the utility model provides, be furnished with protective circuit, as shown in Figure 4 the SD/SIM card.This protective circuit mainly comprises: central processor CPU, resistance R, two incorgruous metal clipss 51,52 and triode 6.Wherein, the GPIO_1 pin of CPU connects an end and the metal clips 51 of resistance R, and the GPIO_2 pin of CPU connects triode 6 (concrete connected mode according to the type of triode and really), and the break-make of triode 6 is controlled by the GPIO_2 of CPU; Another termination one high level of resistance R makes resistance R remain on high level; Incorgruous metal clips 52 ground connection.
With reference to Fig. 3 and Fig. 4, when lid 1 closure, salient point 4 inserts in the middle of the incorgruous metal clips 51,52, and incorgruous metal clips 51 and incorgruous metal clips 52 are separately.Because salient point 4 is an insulator, after incorgruous metal clips 51 and incorgruous metal clips 52 separate, thereby the GPIO_1 of CPU remains on high level state by the high level that resistance R connects, when CPU detects GPIO_1 and is in high level, CPU makes triode 6 be in conducting state to the level signal that GPIO_2 sends 6 conductings of a control triode.Triode 6 connects the power pins (power pins of SD/SIM deck and triode 6 concrete connected modes are decided according to the type of triode) of SD/SIM decks, thereby makes the SD/SIM card obtain powering.This moment, whole system was all in running order.
When lid 1 was opened, the protective circuit of this moment as shown in Figure 5.Salient point 4 breaks away from incorgruous metal clips 51 and incorgruous metal clips 52, incorgruous metal clips 51 and incorgruous metal clips 52 closures, and then the GPIO_1 of CPU is in low level state by incorgruous metal clips 52 ground connection at this moment.When CPU detects GPIO_1 and becomes low level, then start defence program at once, finish preservation operation data on the SD/SIM card.Then, CPU makes triode 6 be in cut-off state to the level signal that GPIO_2 sends the 6 not conductings of a control triode.Stop power supply to SD/SIM card because triode 6 ends this moment, therefore opens the back at lid 1 and just can take out the SD/SIM card.Can effectively prevent warm swap SD/SIM card like this, the data on the protection SD/SIM card are not damaged.
The portable terminal that prevents SD/SIM cassette tape hot-line insertion and extraction that provides by the utility model; can effectively prevent warm swap SD/SIM card, protection SD/SIM card is not damaged or is prevented loss of data on the storage card, and; protective circuit simplicity of design in this terminal is reliable, is user-friendly to.
It will be appreciated by those skilled in the art that the electronic devices and components among the embodiment can be distributed in the device of embodiment according to the embodiment description, also can carry out respective change and be arranged in the one or more devices that are different from present embodiment.The electronic devices and components of the foregoing description can be merged into an integrated circuit.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
