Description
Technical field
The utility model relates to field of vehicle equipment, specifically a kind of car door self-locking gear.
Background technology
Universal along with automobile, increasing people selects trip of driving, and traffic safety is subject to the attention of more and more people, the emphasis of the locking of arrangements for automotive doors safety especially; For the elderly and children, usually because strength is little or misoperation, cause closing of the door not tight, if at this time rashly started up the car, will certainly security risk be there is; In addition, when finding that car door is not closed tight, will certainly go to close car door by larger strength, long-time so operation, can cause the damage of car door.
Utility model content
The purpose of this utility model is to provide a kind of car door self-locking gear, and this blocking device can judge the state of car door, and when car door is not closed tight automatically by car door locking, ensures the safety of personnel.
The utility model solves the technical scheme that its technical problem adopts:
A kind of car door self-locking gear, comprises the single-chip microcomputer be located in car, relay and dc source, being provided with the electromagnet for attracting car door, being provided with angular transducer inside car door in the door pillar of automobile; Power to after dc source serial door handle normally closed switch described device, angular transducer is connected the input interface of single-chip microcomputer respectively with automobile door knob switch; SCM peripheral is also provided with the first power amplifier and the second power amplifier that are connected with its output interface respectively, the output of the first power amplifier is connected with the coil of relay and forms electric loop, and the output of the second power amplifier successively constant open contact of SRE and electromagnet forms electric loop.
In such scheme, single-chip microcomputer is a kind of widely used microprocessor, can carry out analytic operation process to the data signal gathered and analog signal; Power amplifier is that the amplification tiny signal commonly used of electric and electronic field is in order to drive the amplifying device of load; Door handle normally closed switch and automobile door knob switch are all automobile electric switches inherently, and angular transducer, for detecting the angle of car door opening, is also the electrical detection facility that present automotive field is conventional.
The beneficial effects of the utility model are, by the signal of microprocessor detect closing of the door, and according to the car door opening angle that angular transducer feeds back, export the closed door signal of different size, after power amplifier amplifies, send electromagnet to, attract car door locking by electromagnet; The closed door signal of different size can change the electric current by electromagnet, thus produces different magnetic field, controls the strength of closed door, ensure that personal security, avoid the damage of car door simultaneously according to car door opening angle.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is electrical principle block diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of car door self-locking gear, and comprise the single-chip microcomputer 1 be located in car, relay 8 and dc source 4, dc source 4 directly can adopt the dc source in automobile cigarette lighter; Being provided with the electromagnet 11 for attracting car door 12 in the door pillar of automobile, being provided with angular transducer 2 inside car door, body hinge position can be arranged on, for detecting the angle of car door opening; Difference connection angle sensor 2, single-chip microcomputer 1 and automobile door knob switch 3 after dc source 4 serial door handle normally closed switch 5, the other end of automobile door knob switch 3 connects the input signal of input interface as single-chip microcomputer 1 of single-chip microcomputer 1; The car door angle signal input single-chip microcomputer 1 that angular transducer 2 will detect, the periphery of single-chip microcomputer 1 is also provided with the first power amplifier 6 and the second power amplifier 7 be connected with its output interface respectively, the output of the first power amplifier 6 is connected with the coil 10 of relay 8 and forms electric loop, and the constant open contact 9 of the output of the second power amplifier 7 SRE 8 successively forms electric loop with electromagnet 11.
When car door 12 is not closed tight, automobile door knob switch 3 is off state, single-chip microcomputer 1 detects that automobile door knob switch 3 is input as low level, judge that car door 12 is non-latching, and then the car door opening angle that single-chip microcomputer 1 detects according to angular transducer 2, export closed door signal to the second power amplifier 7 corresponding with car door opening angle, output control signals to the first power amplifier 6 simultaneously; First power amplifier 6 exports the coil 10 of relay 8 to after control signal being amplified, coil 10 electric after, the constant open contact 9 of relay 8 closes, power to electromagnet 11 through closed constant open contact 9 after closed door signal amplifies by the second power amplifier 7, electromagnet 11 obtains electric rear generation magnetic field suction car door 12, make car door 12 locking, ensure that the safety of rider.After car door 12 locking, automobile door knob switch 3 closes, and single-chip microcomputer 1 detects that automobile door knob switch 3 is input as high level, judges car door 12 locking, thus stops exporting control signal and closed door signal, and relay 8 dead electricity, cuts off the power supply to electromagnet 11.When opening car door under normal circumstances, door handle normally closed switch 5 disconnects, and stops powering to described blocking device, and single-chip microcomputer 1 can not output signal, and electromagnet 11 can not obtain electric, thus can not hinder the normal unlatching of car door 12.Single-chip microcomputer 1 exports the closed door signal of different size according to the angle of car door opening, change the electric current flowing through electromagnet 11, make electromagnet 11 produce the magnetic field of varying strength, when car door angle is large, the magnetic field of electromagnet 11 is strong, large to the attraction of car door, when the angle hour of car door, the magnetic field of electromagnet 11 is weak, little to the gravitation of car door, while guarantee occupant, with the strength locking car door be applicable to, car door is prevented to be damaged.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to the utility model; Any those of ordinary skill in the art, do not departing under technical solutions of the utility model ambit, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Therefore; every content not departing from technical solutions of the utility model; according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent replacement, equivalence change and modification, all still belong in the scope of technical solutions of the utility model protection.
