Different according to the model of automobile, automobile has two car doors, four car doors or more than four car doors, on each car door
One door interlock switch 4 is set, and the present embodiment is only by taking the automobile with four car doors as an example, the realization to car door alarm device
Mode is specifically described.
The quantity of door interlock switch 4 is four, and four door lock signal receiving terminals 11, a door are provided with door lock controller 1
Lock-switch 4 is connected with a door lock signal receiving terminal 11.Four door interlock switches 4 are connected with audio alarm 2.Then when wherein one
It is a, two, three or four door interlock switches 4 are when being in the state opened, door lock controller 1 is according to four door lock signal receiving terminals
11 signals received would know which corresponding door interlock switch 4 is, then send corresponding signal to display alarm 3,
Corresponding car door is shown by display alarm 3.And when at least one door interlock switch 4 is in the state opened, audio
Alarm 2 sends alarm sound.
Above-mentioned display alarm 3 can be a display, be specifically as follows the display being separately provided, can also integrate
On the instrument board of automobile, display can prompt unlatched car door by multiple display modes.Such as：Display can be passed through
" 1 ", " 2 ", " 3 ", " 4 " indicate left front door, right front door, left back door, right-rear-door, or directly display word " left front door ", " right
Front door ", " left back door ", " right-rear-door ", alternatively, specific car door, this implementation can also be indicated by other symbols, pattern
Example does not limit.
Alternatively, above-mentioned display alarm 3 can be indicator light, its quantity is identical with the quantity of car door.Such as set four
Indicator light, is respectively intended to instruction left front door, right front door, left back door, right-rear-door.Above-mentioned door lock controller 1 has four alarm signals
Number output terminal, each alarm signal output ends are connected with an indicator light.When door lock controller 1 knows unlatched door interlock switch
When 4, signal is sent to corresponding indicator light, is lighted, directly prompting occupant is which car door does not lock.
The effect of above-mentioned intermediate switch device 5 is that control circuit is changed, and when door interlock switch 4 closes, centre is opened
Close device 5 and receive closure signal, then can send signal to audio alarm 2.Intermediate switch device 5 is specifically as follows：After
Electric appliance, breaker etc..Alternatively, technical staff can also build circuit to realize the function of intermediate switch device 5.The present embodiment with
Exemplified by relay, the implementation of car door alarm device is described in detail.
The mode being connected for above-mentioned door interlock switch 4 with door lock controller 1 and audio alarm 2, the present embodiment also provide
A kind of specific mode, those skilled in the art can refer to following mode to realize, or modify to following mode
So as to reach the technique effect identical with the above.
Fig. 2 is the electrical block diagram for the car door alarm device that the utility model embodiment provides.Such as Fig. 2 institutes
Show, four door interlock switches 4 be separately positioned on from left to right left front door, right front door, left back door, on right-rear-door, on door lock controller 1
Four door lock signal receiving terminals 11 correspond to left front door, right front door, left back door, right-rear-door respectively from left to right.Due to four doors
The connection mode all same of lock-switch 4 and other components, thus the present embodiment only to the door interlock switch 4 that is arranged on left front door into
Row describes in detail.Display alarm 3 is eliminated in Fig. 2, this area can be configured according to the above.
One end ground connection for the door interlock switch 4 being arranged on left front door, the other end and corresponding 11 phase of door lock signal receiving terminal
Even.Then when left front door locking, door interlock switch 4 thereon close, corresponding door lock signal receiving terminal 11 receives low level signal.
When left front door is opened, door interlock switch 4 thereon disconnects, and the signal on corresponding door lock signal receiving terminal 11 is always preset height
Level.Then door lock controller 1 would know that the state of four door interlock switches 4 according to the signal of four door lock signal receiving terminals 11.
One end ground connection for the door interlock switch 4 being arranged on left front door, the other end pass through a relay 51 and audio alarm
Device 2 is connected, so that when door interlock switch 4 closes, the coil of relay 51 obtains electric, and movable contact and the stationary contact of relay 51 connect
Touch, to send signal to audio alarm 2.
