A kind of automatic pilot of deployable and collapsible automobile includes mainly that barrier sensory perceptual system, electric-controlled hydraulic execute system and touch
Hit absorption systems composition.Sensory perceptual system includes mainly radar, industrial personal computer, ECU, electric pressure converter etc.；Electric-controlled hydraulic executes system
Hydraulic power unit, solenoid directional control valve 14 and bidirectional hydraulic oil cylinder 1 including microcontroller etc. in electric control gears, hydraulic device etc.；
Collision energy-absorbing system includes steel plate frame 8, honeycomb aluminum plate 9, yielding rubber 10 etc., the insurance being secured by bolts in front of tire
Under thick stick, and ensure that junction has enough rigidity and intensity to meet the impact of collision.
The execution module of whole device is triggered by both of which, and, to automatically control, second is to manually control for the first.By
Barrier threatens relatively small when in view of low speed, and driver also has time enough reaction, therefore under automatic control, entirely
The startup speed of device is 40KM/h, the detection of radar start road pavement barrier.
When detecting barrier in front of wheel, in radar ECU under the parsing of decision algorithm, comprehensive vehicle is fast in real time
The parameters such as degree, obstacle height and distance, calculate the best opportunity of order execution, and send a signal to electric-controlled hydraulic system
System from controller 15 to 14 firing order of solenoid directional control valve, and is powered to electromagnet 5, and driving motor 19 drives hydraulic pump at this time
Hydraulic oil is supplied bidirectional hydraulic oil cylinder 1 by 18 by solenoid valve 14 automatically, and oil cylinder is by piston rod 2 under the high-pressure of hydraulic oil
Quickly stretched out in 1 second, by the rotary shaft 6 with 4 junction of support plate, by the up and down motion of piston rod be converted into steel plate 8 around
The rotary motion of fixed plate rotary shaft 6, as shown in Figures 3 and 4.It is touched to make device rotate down a suitable angle with meeting
It hits.The thrust that hydraulic cylinder 1 keeps certain under the action of hydraulic lock and check valve 17 at this time flicks barrier 11.It is solid simultaneously
Electromagnet 5 due to the buffer unit back lower place keeps working condition, adsorbs the metal sharp objects being likely to occur on ground, until
Troubleshooting finishes that (because different automobile chassis height is different, therefore the specific release range of piston rod 2 need to be sentenced according to actual conditions
It is fixed).When radar does not continue to detect obstacle in 10 seconds, then controller 15 sends out recovery command, disconnects relay switch and opens
Return relay, by solenoid directional control valve 14 to the fuel feeding again of two-way cylinder 1, by 2 fast retractile of piston rod to ensure that automobile exists
Passability under other situations.
When driver is in reply special status, for example encounters macadam pavement, can indoor open voluntarily driven by setting
Dynamic device excludes potential obstacle directly to activate or close hydraulic pressure execution device by manually mode.Radar monitors at this time
It is in standby.
In conclusion the present invention can detect identification front obstacle and start obstacle deflector in time automatically, inhaled by buffering
It can collide removal of obstacle.Buffer unit is due to generating flexible deformation, and impact energy is converted into deformation energy, most of energy quilt at this time
Buffer unit flexible deformation is absorbed, so only less a part of power passes on automobile, to ensure the safety fortune of automobile
Row.After troubleshooting in the recoverable chassis of device, to ensure the passability of automobile under normal circumstances.Such structure not only has enough
Bond strength, and have certain elasticity, improve the troubleshooting ability of obstacle deflector.
Above is only presently preferred embodiments of the present invention, and of course, the scope of rights of the present invention cannot be limited by this,
Therefore according to equivalence changes made by scope of the present invention patent, still belong to protection scope of the present invention.
