Collision-proof device for opening automobile door of the present utility model can enter mode of operation under trigger element triggers, utilization is arranged on the detector for moving object on automobile tail left side and right side, mobile object to the vehicle side rear is surveyed, and detection data judges after microprocessor unit is processed.When the judgement mobile object may bump with car door, start vehicle door lock mechanism pinning car door and forbid opening, and send sound and light alarm by alarm unit simultaneously, remind the operator to note, avoid crashing.
Preferably, described trigger element consists of inductive switch.
Due to trigger element and the interlock of automobile door opening handle, adopt inductive switch when the operator contacts Door Handle preparation opening car door, trigger microprocessor unit and make device enter mode of operation, and now car door not yet to be unlocked.May bump in car door if detect mobile object, can drive in time vehicle door lock mechanism doors locked, prevent collision case
Concrete, described microprocessor unit comprises the microprocessor that model is C8051.
The microprocessor that model is C8051, be that a application is general, and the microprocessor of technology maturation is applicable to application collision-proof device for opening automobile door of the present utility model very much.
Further, described detector for moving object is the microwave detector that is operated in X-band.
Employing is operated in the microwave detector detecting mobile object of X-band, and the mobile object that is suitable for very much road environment is surveyed, and the maturation that possesses skills, characteristics that cost is low.
Concrete, described microwave detector frequency of operation is 10.52GHz ± 5MHz.
At this working frequency range, to disturb littlely, rate of false alarm is low.
Recommend, described microwave detector model is HB100.
The microwave detector that model is HB100 is the Doppler mobile sensor module that Agilis communication technology company opens, and has low-power consumption, characteristics that heat stability is good, is high sensitivity and moving Object Detection device cheaply.
The beneficial effects of the utility model are, can effectively prevent that vehicle parking from opening the collision case that car door causes, and have practical value and social benefit preferably.The utlity model has simple in structure, the characteristics that cost is low, its technology can well be carried out integrated optimization with the vehicle prior art, further reduces costs.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment.
Fig. 2 is software control flow chart.
The specific embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
Collision-proof device for opening automobile door of the present utility model, utilization is arranged on the detector for moving object on automobile tail left side and right side, mobile object to the vehicle side rear is surveyed, when detecting mobile object and may bump with car door, starting vehicle door lock mechanism pinning car door forbids opening, and send sound and light alarm by alarm unit simultaneously, and remind the operator to note, avoid crashing.
