Portable beam described in the application stretches out actuating device, refers to and portable beam can be driven outwardly directed electromechanical device.Portable beam stretches out actuating device form to be had varied, and it is mainly divided into mechanical type and electromechanical etc.Be the most simply with spring in mechanical type, utilize spring force that portable beam is driven protruding.Mechanical type can also comprise fluid pressure type and vapour-pressure type etc.; Electrodynamic type drives portable beam protruding primarily of motor by the form such as tooth bar or chain.The application stretches out actuating device to portable beam does not have particular/special requirement, all can portable beam outwards drive the device stretched out all be applicable to this programme use.
Portable beam described in the application stretches out blocking device and refers to and protruding portable beam locking of going, can meet machinery or the electromechanical device of shock.The application stretches out blocking device to portable beam does not have particular/special requirement, and machinery or the electromechanical device of all portable beam lockings can gone protruding all be applicable to the present invention's use.Portable beam stretches out blocking device and mainly includes lock hook bayonet type, bolt-type, pawl type etc.
In order to crashproof and don't increase the overall length of automobile better, the present invention is divided into fixed beam and portable beam the collision prevention girders of automobile.Wherein, fixed beam comprises fixing longeron and fixed cross beam; Portable beam comprises moved cross beam and moveable longitudinal beam.Portable beam is arranged on fixed beam, and portable beam can move relative to fixed beam horizontal extension.The physical construction that can realize this connection mode has varied, and simultaneously the present invention does not have particular/special requirement to it, allly can meet above-mentioned needs such as, sleeve type, buckle-type and guide tracked etc. be all applicable to the application's use; Fixed cross beam 10 is equipped with portable beam retraction blocking device, portable beam retraction blocking device can lock the retraction state of portable beam.The portable beam retraction blocking device of this example forms primarily of electromagnet 8, lock hook 9 and snap close 12.Lock hook is hinged on fixed cross beam 10, and the iron of one end of lock hook 9 hooks for locking moved cross beam 7, and the other end of lock hook 9 is hinged with electromagnet 8, and electromagnet 8 is installed with on fixed cross beam 10.When moved cross beam retraction, lock hook just in time catches on the snap close 12 on moved cross beam, and portable beam is pinned.When electromagnet 8 receive computing machine unlock instruction and adhesive time, lock hook 9 departs from snap close 12, and portable beam can freely stretch out.As shown in Figures 2 and 3.
The portable beam of this example stretches out actuating device and forms primarily of spring 4.One end of spring 4 is fixed on moveable longitudinal beam 11, and another end is fixed on fixing longeron 2, as shown in Figure 3, shown in Fig. 4.When lock hook 9 discharges, portable beam is just protruding under the action of the spring, completes the task of driving.
In order to portable beam can be made to bear shock, fixed beam is also equipped with portable beam and stretches out blocking device.The state of stretching out that portable beam stretches out blocking device lockable portable beam meets shock.The portable beam of this example stretches out blocking device and mainly comprises the formations such as lock hook 3, hinge 5, support 6 and spring.End position when the corresponding moveable longitudinal beam 11 of fixing longeron 2 stretches out has a hole, and lock hook 3 can catch on locking through this hole moveable longitudinal beam 11.Lock hook 3 is on the frame 6 hinged by hinge 5, and support 6 is fixedly mounted on fixing longeron 2, and hinge 5 is equipped with spring, and spring makes lock hook 3 press to the direction of moveable longitudinal beam.Once portable beam is protruding, lock hook is just its locking.
Stretch out when wanting portable beam to need, when not needing, retraction collection, does not so just increase the overall length of automobile.But doing and produce a new problem like this, is exactly how to make portable beam can stretch out when needed.For this reason.The present invention installs distance measuring equipment (DME) on automobile, and distance measuring equipment (DME) connects computing machine, and computing machine connects portable beam retraction blocking device.The data transmitted according to distance measuring equipment (DME) by computing machine are made by blas and being judged accurately.
Working process of the present invention: under portable beam normal condition be retraction collection and locked as shown in figures 1 and 3 by portable beam retraction blocking device.At this moment the external tensioning arm-to-arm of spring 4; In the process of moving, the distance of this car and (this device be contained in before) obstacle above constantly measured by distance measuring equipment (DME) to automobile.Distance measuring equipment (DME) passes to computing machine the data recorded, and computing machine is by the relative velocity of these data reduction cost cars with obstacle above.Computing machine presses these data of blas process.When data display, the relative velocity of Ben Che and above obstacle and straight-line distance reach the hazard level of program setting.Such as when relative velocity be greater than 10 kilometers/hour, straight-line distance be less than 2 meters time, computing machine just sends unlock instruction to electromagnet 8, allows portable beam freely stretch out.After the electromagnet 8 of portable beam blocking device receives the instruction of computing machine, adhesive is unblanked, and lock hook 9 departs from snap close 12, and portable beam, under the driving of portable beam actuating device, is namely shot out under the driving of spring 4.When portable beam reaches stop, the lock hook 9 that portable beam stretches out on blocking device just locks moveable longitudinal beam 11, allow it can not after go to move back and withstand shocks, as shown in Figure 2 and Figure 4.
The definition of above-mentioned hazard level depends primarily on the reaction time of system, and wherein portable beam stretches out the required time is crucial.The faster the better for the speed of response of system, and real reaction speed can be determined by actual measurement.The front of automobile is contained in for the present invention.For guaranteeing safety, before colliding, portable beam must be protruding.Relative distance Y between the barrier foreign object in that is automobile and front, divided by the relative velocity X between current automobile and barrier foreign object, the time T of gained, must be greater than the reaction time Z of system, and this guarantees the safe most important condition.That is when Z is for time fixing, X is larger, and permission distance (danger range under this speed) between automobile and barrier foreign object is longer.Otherwise it is then anti-.This relation describes has different warning distances (or claiming danger range) under different relative velocities.This rule is just applicable to automobile varying environment in use, and it effectively can avoid misoperation.Such as when parking area berth, automobile is very little with the relative speed of a motor vehicle X of periphery object, because Z has been fixing, so allow automobile just very little with the relative distance (danger range under this speed) of barrier foreign object.Can guarantee park be time, very little relative distance Y, portable beam also can not stretch out by mistake.On the other hand, when automobile is with normal speeds, the relative distance that system allows just increases greatly.These characteristics conform to surface conditions.
In order to make the moveable longitudinal beam 11 of portable beam can absorbing impact energy better, moveable longitudinal beam 11 can make the multistage of tool varying strength.The means that can reach this target have multiple.Such as, the multistage that moveable longitudinal beam can be struck out thickness or varies in size; Can also at multistage form opening different bore hole etc.Each section of moveable longitudinal beam can be made so all to have different mechanical strengths, moveable longitudinal beam can be out of shape instead of whole piece flexural deformation in order.Greatly can improve anti-collision effect like this.
The present invention can be contained in the shock of this four direction of Initiative Defense in the four direction of automobile and front, rear, left and right side.No matter install in which direction, as long as install instantaneous distance coupled computer that distance measuring equipment (DME) measures the rammer in this direction in a respective direction, just can to realize active crashproof.
