Description
Technical field
The present invention relates to a kind of safety device of vehicle, especially relate to a kind of vehicle anticollision vehicle door self-locking device.
Background technology
The associated safety system being applied at present on car has reversing warning, the outer camera of reverse image and car.
This technology of reversing warning, for during driving and when parking, gives a warning to driver for the car in driver blind area or object.Conventionally, this system can respond in the time that driver drives a vehicle; It may make a warning marker in back mirror glimmer, the warning of simultaneously can sounding, and this system is a short distance checking system.
Reverse image and rear view camera are one, not only protect car, can also avoid surprisingly injuring children and animal in the time of reversing.Reversing from downward-sloping back mirror or sound warning to real time inspection.A new generation's technology comprises a pick up camera, it can with navigationsystem collaborative work, your after one's death all are carried out to wide angle shot, be then reflected in car on screen, thereby help you to move backward or articulate trailer.
In sum, can see and on car, carry radar and camera is very general.A lot of companies are all being devoted to improve the limitation of automobile as a bounded system.But this can greatly reduce car door collision self-locking system the system of car door collision case frequency now and also not be applied on car.
Summary of the invention
Object of the present invention is exactly to provide a kind of vehicle anticollision vehicle door self-locking device in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of vehicle anticollision vehicle door self-locking device, comprises signal collection device, signal processor unit and executive device, wherein
Signal collection device is sensor group, for detection of the mobile message of object on rear view of vehicle road;
Signal processor unit, is the ECU of vehicle, is connected with sensor group, receives the detection signal from sensor group, and processes, and judges whether rear object can bump with the car door of opening;
Executive device, comprise Door Lock, loudspeaker, stop gear, hand switch and car light, be all connected with ECU, in the time that ECU judges that rear object can bump with the car door of opening, send control signal control Door Lock doors locked, the car light that simultaneously glimmers, ring loudspeaker; If when ECU sends control signal, car door is opened, by stop gear by vehicle door lock in current location; Described hand switch is for manually removing the lock-out state of Door Lock or stop gear.
Described sensor group comprises several ultrasonic transduters, and its detection range is the fan-shaped range of 50 ° of rear view of vehicle, and detecting distance is 5m.
The detection frequency of described ultrasonic transduter is at least 25Hz.
Described stop gear is fluid control structure, is connected with the rotating mechanism of car door, comprises two logical two-position valve and the hydraulic actuating cylinders that connect by oil pipe.
Compared with prior art, the present invention has advantages of the following aspects:
One, cost aspect: whole system cost is lower, can utilize vehicle existing apparatus, and cost compressible space is very large.
Two, aspect, market: also there is no at present similar system applies in market, and for the poor condition of road surface of China and driver like arbitrarily stopping servant's bad driving habit, native system put into production now very large potentiality and value.And native system implements fairly simple practicality, neither be very difficult for automobile vendor.
Three, secure context: system has ensured the upper passenger's of pedestrian and Che safety to greatest extent on one's own initiative, can effectively reduce accident rate, reduces car owner's loss
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram of stop gear in the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of vehicle anticollision vehicle door self-locking device, comprises signal collection device, signal processor unit and executive device.Wherein, signal collection device is sensor group 1, for detection of the mobile message of object on rear view of vehicle road, is made up of several ultrasonic transduters, and its detection range is the fan-shaped range of 50 ° of rear view of vehicle, and detecting distance is 5m.In order to ensure the real-time rate of mobile message, the detection frequency setting of ultrasonic transduter, at 27Hz, ensures the pulse of every 37ms left and right transmitting one-time detection.
Signal processing device is set to the ECU2 of vehicle, is connected with sensor group 1, receives the detection signal from sensor group 1, and processes, and judges whether rear object can bump with the car door of opening;
Executive device comprises Door Lock 3, loudspeaker 4, stop gear 5, hand switch 6 and car light 7, all be connected with ECU2, in the time that ECU2 judges that rear object can bump with the car door of opening, send control signal control Door Lock 3 doors locked, glimmer simultaneously car light 7, ring loudspeaker 4, give the alarm and point out.Stop gear 5 is as parts that step up security, and concrete structure as shown in Figure 2, adopts fluid control structure, is connected with the rotating mechanism of car door, comprises two logical two-position valve 51 and the hydraulic actuating cylinders 53 that connect by oil pipe 52.Its function is the generation that prevents extraordinary circumstances, before ECU2 sends locked signal to Door Lock 3, car door is opened, now Door Lock can not be by Door Lock, therefore, ECU2 can send stuck signal to stop gear 5 simultaneously, if car door is opened, stop gear 5 meeting horse backs, by locked car door to existing position, prevent that the angle that its unlatching is larger and the object collision being come by rear view of vehicle from causing danger.If after giving the alarm, occupant observes the danger that ambient conditions do not have an accident really, can control by the hand switch 6 on car the lock-out state of ECU5 releasing Door Lock 4 or stop gear 5.
Principle of work of the present invention is as follows:
(a), in the time that automobile stops, sensor group starts automatically, thus object in induction setting range, detector mobile message.
(b) sensor group collects the mobile message of mobile object, and data are sent to ECU.
(c) ECU processes according to the program of setting, and this program is by the mobile message such as current location and speed of rear object, and whether the object of judging in scope can bump against with car door within a certain period of time.
(d) if judgement is likely bumped against, ECU control Door Lock is closed, and car door cannot be opened, and dangerous information is shown to the car light that simultaneously glimmers, the alarm of ring loudspeaker at vehicle-carrying display screen.
(e) situation of having opened for car door, ECU can control stop gear, makes car door be fixed on certain position, prevents further opening of car door, to avoid dangerous generation.
