Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
Description of drawings
Fig. 1 is the decomposition diagram that has the notebook computer of burglar alarm of the present invention;
Fig. 2 is the structural drawing of the burglar alarm among Fig. 1;
Fig. 3 is the existing notebook computer exploded view that does not have burglar alarm.
Embodiment
Fig. 1 is the decomposition diagram that has the notebook computer that is built in the burglar alarm in the main frame according to of the present invention.As shown in Figure 1, one-piece construction according to notebook computer of the present invention, except increasedburglar alarm 70 and thelockset socket 17 corresponding with it and burglaralarm holding portion 27 are caused on top shell 11 structural difference, almost be the same with the structure of above-mentioned conventional notebook computer.
Therefore, can be incorporated to the integrally-built description of conventional notebook computer, below the main special construction of describingburglar alarm 70 and burglar alarm holding portion 27.In conventional notebook computer and in the notebook computer of the present invention, identical label is represented identical parts.
As shown in Figure 1 and Figure 2, notebook computer according to the present invention has thelockset socket 17 of the on-off control unit 73 that is used to exposeburglar alarm 70; Betweenlockset socket 17 andmainboard 20, forming burglar alarmspatial accommodation 27 on thedrain pan 13; And theburglar alarm 70 that is contained in the burglar alarm spatial accommodation.
On top shell 11, be provided withlockset socket 17, so that expose the on-off control unit 73 ofburglar alarm 70.
Betweenlockset socket 17 andmainboard 20, having formed burglar alarmspatial accommodation 27 on thedrain pan 13, be used to holdburglar alarm 70.
As shown in Figure 2,burglar alarm 70 is made of a level sensor assembly 71 and warning circuit assembly 72 and an on-off control unit 73, links to each other with lead respectively between level sensor assembly 71, warning circuit assembly 72 and the on-off control unit 73.
Level sensor assembly 71 has: the inside that is made of insulating material has the spherical shell 711 of positive spherical hollow space; Be contained in the metal spherical crown 712 in spherical shell 711 cavitys, metal spherical crown 712 is greater than hemispheroidal spherical crown; The top contact 713 of metal is arranged at spherical shell 711 tops; The bottom contact 714 of metal is arranged at spherical shell 711 bottoms.
Warning circuit assembly 72 has: warning circuit 721; Send the electric sound-producing device 722 of alarm sound.This warning circuit assembly 72 can be arranged in themain frame 10 of notebook computer, also can be arranged on the display back side.
On-off control unit 73 has: tapered end 731; The power supply 732 of the burglar alarm that forms with independent battery; With the supporting key 733 of tapered end; Be subjected to the power switch 734 of tapered end 731 controls.
When locking by 733 pairs of tapered ends 731 of key, when making on-off control unit 73 be in locking state, power switch 734 is open-minded, andwhole burglar alarm 70 is in charged duty.
Whennotebook host 10 was in level or level of approximation laying state, the bottom contact 714 of horizon sensor assembly 71 contacted with metal spherical crown 712 and electricity is connected; The top contact 713 of level sensor assembly 71 disconnects and electrical isolation with metal spherical crown 712.The entire circuit of horizon sensor assembly 71 is in off-state, and level sensor assembly 71 alarm free signals transmit to warning circuit assembly 72.
Warning circuit assembly 72 is not when receiving the alerting signal that level sensor assembly 71 sends, and warning circuit 721 is in off state, do not produce the electric current that drives electric sound-producing device 722.Electricity sound-producing device 722 is sounding alarm not.
When the level ofnotebook host 10 or level of approximation laying state were significantly changed, the top contact 713 of level sensor assembly 71 all contacted with metal spherical crown 712 with bottom contact 714 and electricity is connected.The entire circuit of level sensor assembly 71 is in on-state, and level sensor assembly 71 sends alerting signal to warning circuit assembly 72.
Warning circuit assembly 72 is after receiving the alerting signal that level sensor assembly 71 sends, and warning circuit 721 is in opening state, produces the electric current that drives electric sound-producing device 722.Electricity sound-producing device 722 sounding alarms.After warning circuit assembly 72 was opened warning, the disappearance of the alerting signal of sending because of horizon sensor assembly 71 did not stop to report to the police.
Afterburglar alarm 70 is reported to the police, unblank by key 733, remove the locking state of on-off control unit 73, power switch 734 turn-offs, and warning circuit assembly 72 stops to report to the police.
In above scheme, power supply 732 is single independently battery supply.But power supply 732 also can be the cells in notebook computer power supply shared with other equipment of notebook computer, or the power supply that is made of jointly cells in notebook computer power supply and independent battery power supply.And, can power supply be set respectively for horizon sensor assembly 71 and warning circuit assembly 72.Warning circuit assembly 72 has adopted electric sound-producing device 722, also can adopt other forms of electric alarm device, as: light warning device, acousto-optic combinde alarms device or electromagnetism warning device etc.
In above scheme, adopted horizon sensor assembly 71 with metal spherical crown 712 and insulation spherical shell 711, also can adopt other forms of horizon sensor; On-off control unit 73 with tapered end 731 and key 733 also can adopt other lockset forms, as: coded lock, button lockset, electronic lock (can connect the radio alarming element) etc. as the auto alarm electronic lock.
Another kind of embodiment of the present invention is, power switch and lockset are arranged on the warning circuit assembly, be connected with power supply and warning circuit, thus the output of control alerting signal.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
