Abstract
The invention discloses a notebook PC with an anti-theft and alarm device, comprising a battery, an external power supply and a shell body, wherein, the external power supply is connected with both electric poles of the battery, and an alarm which is connected with the external power supply in parallel and then is connected with both electric poles of the battery. In the invention, the external power supply and the alarm are connected to the battery in parallel, the alarm does not work due to being shortcircuited by the external circuit under the circumstances that the external power supply is plugged in, when the notebook PC is stolen and unplugged the external power supply, the alarm is communicated with the battery to alarm; the invention has simple structure, low cost, and is easy to realize.
Description
Technical field
The present invention relates to a kind of notebook computer, relate in particular to a kind of notebook computer with burglar alarm.
Background technology
Present notebook computer is less because of its volume, when using in some public situation such as exhibition, under the situation that the user pays no heed to, is easy to have things stolen.In the middle of the prior art, the anti-theft device of notebook computer is arranged, but these apparatus structure complexity, some in addition to do bigger change to notebook computer, use inconvenience.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of notebook computer of simple in structure, the band burglar alarm that is easy to realize is provided.
Purpose of the present invention is realized by the following technical programs:
A kind of notebook computer with burglar alarm comprises battery, external power supply and housing, and described external power supply links to each other with the two poles of the earth of described battery, also comprises alarm, described alarm and the two poles of the earth that are connected described battery after described external power supply is in parallel.
Above-mentioned notebook computer also comprises divider resistance, and is in parallel with described external power supply after described alarm is connected with described divider resistance.
Above-mentioned notebook computer also comprises switch, and is in parallel with described external power supply after described switch is connected with described alarm.
Above-mentioned switch is arranged on the bottom of described housing.
Above-mentioned alarm is a hummer.
Above-mentioned alarm comprises wireless transmitter module and receiving alarm module, and described wireless transmitter module is in parallel with described external power supply, and described receiving alarm module comprises the interconnective receiver and second hummer.
The present invention's beneficial effect compared with prior art is:
(1) the present invention is by external power supply and alarm and be connected on the battery, and under the situation of inserting external power supply, this alarm is not worked by the external circuits short circuit, when computer is stolen when taking out external power supply, and alarm and battery UNICOM and report to the police;
(2) switch is set, convenient when the occasion work that does not need to report to the police, the cancellation warning function;
(3) switch is arranged on computer casing bottom, is not easy to be found by stealer and cancels warning;
(4) alarm adopts the radio alarming device, receiver module can be positioned over the place of easily being discovered, and has improved the efficient of reporting to the police.
(5) the present invention is simple in structure, and is with low cost, is easy to realize.
Description of drawings
Fig. 1 is the embodiment of the invention 1 a warning device circuit diagram;
Fig. 2 is the embodiment of the invention 2 warning device circuit diagrams;
Fig. 3 is the embodiment of the invention 2 receiving alarm module circuit diagrams.
Embodiment
Use specific embodiment in conjunction with the accompanying drawings the present invention to be described in further detail below.
One embodiment of the present invention as shown in Figure 1, comprise battery V1, external power supply V2, switch S, divider resistance R1 and alarm A0.Be connected in the two poles of the earth of battery V1 after alarm A0 connects with divider resistance R1 and switch S in parallel with external power supply, present embodiment alarm A0 is a hummer.Switch can be arranged on the bottom of notebook computer casing, and the position is hidden, is not easy to discover.
Principle of work of the present invention is: when notebook computer inserts external power supply V2, Closing Switch S starts working, and because of the access of external power supply V2 forms short circuit to alarm A0 and divider resistance R1, alarm A0 does not work.When computer is stolen, certainly will external power supply to be taken out, battery V1 and alarm A0 constitute the loop, and alarm A0 reports to the police.When not needing antitheft occasion work usually, switch S can be disconnected.
Another embodiment of the invention, as Fig. 2, shown in Figure 3, the difference of itself and first kind of embodiment is, alarm A0 comprises wireless transmitter module A1 and receiving alarm module A2, wireless transmitter module A1 is connected the position of first kind of embodiment alarm A0, receiving alarm module A2 further comprises receiver RM, the second battery V3, second resistance R 2 and the second hummer B of series connection successively, when external power supply takes out, wireless transmitter module A1 sends signal, receiving alarm module A2 connects circuit after receiving signal, and the second hummer B begins to report to the police.Receiving alarm module A2 can be placed apart with notebook computer, as carried the convenient situation of knowing that in time computer is stolen by the user.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
