Abstract
The utility model discloses an automatic rebounding type engine hood bouncing system, comprising a pedestrian detection apparatus which is disposed in front of a vehicle for identifying whether a pedestrian appears with the dangerous range in front of the vehicle, a distance-measuring senor which is disposed in front of the vehicle and measures the distance between the vehicle and a pedestrian when the pedestrian enters into the dangerous range, a speed sensor which is disposed on a speed changer output shaft for simply detecting vehicle speed, a central control unit used for analyzing whether a bump is about to occur, and a lifting mechanism for lifting the engine hood. The automatic rebounding type engine hood bouncing system is advantageous in that damage to a human head when a pedestrian bumps into a vehicle can be reduced, and automatic rebounding can be realized.
Description
Technical field
The car bonnet that the utility model relates on a kind of automobile bounces up system, and particularly a kind of self-reset car bonnet for pedestrian protecting bounces up system.
Background technology
When pedestrian and vehicle generation traffic accident, the topmost cause of death is the injury that comes from pedestrian head, and when automobile and pedestrian bumped, if the speed of a motor vehicle is very fast, the pedestrian will be hit to such an extent that fly up, and head hits on car bonnet or the front windshield then.Be exactly hard driving engine below the car bonnet, if directly bump against, can cause very serious injury to the pedestrian.Therefore, want to protect pedestrian's head, just enough buffer distances must be arranged between car bonnet and the driving engine.Bounce up system so introduced car bonnet.
But be to use the cartridge explosive gunpowder to upspring behind the engine case, need be repaired by the technician to monopolized store.
Summary of the invention
The utility model technical issues that need to address are, overcome disadvantages of background technology, provide a kind of simple and reasonable, can bounce up system by the self-reset car bonnet after bouncing up.
In order to realize above-mentioned task, the utility model adopts following technical solution to be achieved:
A kind of self-reset car bonnet bounces up system, comprise pedestrian detection device, also comprise distance measuring sensor, speed sensor, Central Processing Unit (CPU) and driving engine lifting mechanism, wherein distance measuring sensor, speed sensor and pedestrian detection device link to each other with the Central Processing Unit (CPU) input end respectively, and the Central Processing Unit (CPU) mouth links to each other with the car bonnet lifting mechanism.
The utility model also has following technical characterstic:
Described car bonnet lifting mechanism, comprise car bonnet, lifting device, hood hinge, hinge rotating shaft, snap close guide rod and snap close body, wherein the snap close body is positioned at an end of car bonnet by the snap close guide rod, the lifting device is fixed in the other end of car bonnet by hood hinge, and hood hinge can rotate around the hinge rotating shaft.
Of the present utility model for pedestrian protection system, to the infringement of pedestrian head, can also automatically reset when alleviating pedestrian and auto against.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Fig. 2 is car bonnet lifting mechanism work scheme drawing.
Fig. 3 is car bonnet lifting mechanism working timing figure.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The specific embodiment
Referring to Fig. 1, a kind of self-reset car bonnet bounces up system, comprise that pedestrian detection device also comprises distance measuring sensor, speed sensor, Central Processing Unit (CPU) and driving engine lifting mechanism, wherein distance measuring sensor, speed sensor and pedestrian detection device link to each other with the Central Processing Unit (CPU) input end respectively, and the Central Processing Unit (CPU) mouth links to each other with the car bonnet lifting mechanism.
Wherein pedestrian detection device is installed in vehicle front, and whether be used for has the pedestrian to occur in the identification vehicle front risk range; Distance measuring sensor is installed in vehicle front, measuring vehicle and pedestrian's distance when the pedestrian enters risk range.Speed sensor is installed on the transmission output shaft, is used for letter and detects car speed.Central Processing Unit (CPU) is used for analyzing data, and factors such as the comprehensive discriminatory analysis speed of a motor vehicle, people-following distance if think that collision is inevitable, then send and instruct to lifting mechanism, make its lifting car bonnet.When people-Che bumped, car bonnet lifting was ready, thereby can effectively alleviate the pedestrian head injury.If vehicle does not bump with the pedestrian, namely checking system is reported by mistake, and after a period of time after the car bonnet lifting, the lifting mechanism counter motion drives car bonnet and moves to the front lower place, and until restPosing, the realization system resets.
Referring to Fig. 2, for car bonnet lifting mechanism work scheme drawing, comprise car bonnet 1, lifting device 2, hood hinge 3, hinge rotating shaft 4, snap close guide rod 5, snap close body 6.Lifting device two ends are hinged to respectively on vehicle body and the hood hinge, hood hinge can be done circular motion under the guiding of hinge rotating shaft simultaneously, the bonnet latch guide rod can slide along the snap close body, and therefore under the lifting device promoted, car bonnet can rise to the back upper place; Same car bonnet also can reduce to the front lower place under the pulling of lifting device, resets with realization.
Referring to Fig. 3, pedestrian detection device on being installed in vehicle recognizes when having the pedestrian to occur in the vehicle front risk range, and factors such as the Central Processing Unit (CPU) comprehensive analyses speed of a motor vehicle, people-following distance are if think that collision is inevitable, then send and instruct to lifting mechanism, make its lifting car bonnet.When people-Che bumped, car bonnet lifting was ready, thereby can effectively alleviate the pedestrian head injury.If vehicle does not bump with the pedestrian, namely checking system is reported by mistake, and after a period of time after the car bonnet lifting, the lifting mechanism counter motion drives car bonnet and moves to the front lower place, and until restPosing, the realization system resets.
Selecting model in this embodiment is Central Processing Unit (CPU) for the AT89C51 micro controller system.
Selecting PEUGEOT 406 is speed sensor, and this speed sensor survey precision can reach 99.9%.
Select SENST series laser range sensor, this serial laser range sensor can measure target ground distance fast and accurately, result of a measurement can be transferred on the equipment by various interface, and the control of laser range sensor simultaneously also can be finished by computing machine or other coupled equipment.Adopt red laser aiming mode accurately, the precision height, range is big, and has abundant output interface.
Self-reset car bonnet of the present utility model bounces up system, can effectively improve the pedestrian head protective value of vehicle body.And this device can repeated usage, has reduced the maintenance cost that system's wrong report causes.
