Description
Technical field
The utility model relates to the auto parts machinery technical field, especially a kind of new automobile door lock controller.
Background technology
Along with the raising of living standards of the people and the fast development of science and technology, automobile has entered vast family, and is annual with surprising quantity increase.Meanwhile, vehicle safety and antitheftly just become current important topic.Automobile all is equipped with electric door lock mostly now, and present existing door lock gauge tap all needs driver or passenger's manual operation, and central door lock control device comes the driving gate lock actuator to reach the purpose of unblanking or shutting according to the state of door lock gauge tap signal.
There is following shortcoming in existing door lock controller: 1, unblank or shut all to want driver or passenger's manual operation switch to finish, increased operation link, cause in the driving driver or passenger to neglect locking the door easily, personnel in the car and property are produced potential safety hazard; If 2 door locks are under the state that shuts, when collision happens or accident, if the occupant can not unblank by active operation door lock gauge tap, car door can't normally be opened from the outside, can influence rescue time, causes casualties.
The utility model content
At the weak point that exists in the above-mentioned technology, centrally controrlled locking system shut and the new automobile door lock controller of auto-unlocking when crashing automatically when the utility model provided a kind of vehicle '.
For achieving the above object, the utility model provides a kind of new automobile door lock controller, comprise shell and internal circuit board, described internal circuit board is provided with power circuit, single-chip microcomputer, also comprise acceleration transducer on the described internal circuit board, the motor operation detecting circuit, car door lock status signal testing circuit, car door lock control signal output circuit, described single-chip microcomputer is connected with described power circuit and described acceleration transducer, described motor operation detecting circuit, described car door lock status signal testing circuit, described car door lock control signal output circuit is connected with described single-chip microcomputer.
Described motor operation detecting circuit is mainly finished by optocoupler, by optocoupler signal is isolated, and converts the receptible signal of single-chip microcomputer to, passes to single-chip microcomputer then.
Described car door lock status signal testing circuit is mainly finished by optocoupler, by optocoupler signal is isolated, and converts the receptible signal of single-chip microcomputer to, passes to single-chip microcomputer then.
Described internal circuit board is arranged in the shell, described shell screw and the fastening installation of body of a motor car.
Described car door lock control signal output circuit links to each other with former car circuit, controls unblanking and shutting of car door.

Compared with prior art, the utlity model has following advantage:
The new automobile door lock controller that the utility model provides, centrally controrlled locking system can shut automatically when vehicle ', and is bumping or can auto-unlocking during emergency episode, can reduce casualties, shortens rescue time.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The critical element symbol description is as follows:
1, power circuit 2, single-chip microcomputer 3, acceleration transducer
4, car door lock status signal testing circuit 5, motor operation detecting circuit
6, car door lock control signal output circuit
The specific embodiment
In order more clearly to explain the utility model, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model provides a kind of new automobile door lock controller, comprise shell and internal circuit board, internal circuit board is provided with power circuit 1, single-chip microcomputer 2, also comprise acceleration transducer 3, motor operation detecting circuit 5, car door lock status signal testing circuit 4, car door lock control signal output circuit 6 on the internal circuit board, single-chip microcomputer 2 is connected with power circuit 1 and acceleration transducer 3, and motor operation detecting circuit 5, car door lock status signal testing circuit 4, car door lock control signal output circuit 6 are connected with single-chip microcomputer 2.The motor operation detecting circuit is mainly finished by optocoupler, by optocoupler signal is isolated, and converts the receptible signal of single-chip microcomputer to, passes to single-chip microcomputer then; Car door lock status signal testing circuit also is mainly to be finished by optocoupler, by optocoupler signal is isolated, and converts the receptible signal of single-chip microcomputer to, passes to single-chip microcomputer then.Car door lock control signal output circuit 6 links to each other with former car circuit, controls unblanking and shutting of car door; Power circuit 1 links to each other with the motor electric oil pump, and power circuit 1 is with the operating voltage conversion cost controller operating voltage of automobile.。
Operating principle:
When human pilot is piloted engine, the motor electric oil pump is started working, the power module of Xiang Lianing obtains voltage therewith, this controller is started working, at first finish the initial work of single-chip microcomputer and acceleration transducer, the car door lock status signal is input to single-chip microcomputer by the mode of interrupting, and unblanks or the state that shuts in that the single-chip microcomputer internal record is current.Then, gather at interval in required time by the detected vehicle acceleration of acceleration transducer, at first the crash acceleration of preserving in degree of will speed up value and the single-chip microcomputer memory is compared, if meet or exceed this value, then thinks to have taken place collision, at this moment, no matter car door lock is unblanked or the state that shuts, and single-chip microcomputer all sends unlocking signal, and signal is sent to the controller of former car centrally controrlled locking system system by electric wire, controller is received signal, opens car door lock.If the accekeration that single-chip microcomputer collects is less than the crash acceleration value of preserving in the single-chip microcomputer memory, single-chip microcomputer with this accekeration by calculating the instantaneous velocity of vehicle, and the speed of locking a door of preserving in this instantaneous velocity value and the single-chip microcomputer memory compared, if instantaneous velocity is greater than the speed of locking a door, and car door lock is a unlocked conditions, then single-chip microcomputer sends the pass lock signal, signal is sent to the controller of former car centrally controrlled locking system system by electric wire, controller is received signal, the closed door lock.If car door lock has been the state that shuts, then do not send the pass lock signal, avoid repeating to lock a door.
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 domain of the present utility model.
