Walking beam described herein stretches out driving means, refers to walking beam can be driven outwardly directed electromechanical device.Walking beam stretches out driving means form to be had varied, and it is broadly divided into mechanical type and electromechanical etc..Simplest in mechanical type is to use spring, using spring force, walking beam is driven protruding.Mechanical type can also include fluid pressure type and vapour-pressure type etc.；Electrodynamic type is mainly driven walking beam by forms such as tooth bars or chain protruding by motor.The application stretches out driving means to walking beam does not have a particular/special requirement, all can outwards drive the device stretching out to be suitable for this programme walking beam to use.
Walking beam described herein stretches out locking device and refers to the protruding walking beam going can be locked, and meets machinery or the electromechanical device of shock.The application stretches out locking device to walking beam does not have particular/special requirement, all machineries that the protruding walking beam going can be locked or electromechanical device be suitable for the present invention and use.Walking beam stretches out locking device and mainly includes lock hook lock catch type, bolt-type, pawl type etc..
For preferably anticollision and the overall length not increasing automobile, the present invention is divided into fixed beam and walking beam the collision prevention girders of automobile.Wherein, fixed beam includes fixing longeron and fixed cross beam；Walking beam includes moved cross beam and moveable longitudinal beam.Walking beam is arranged in fixed beam, and walking beam can be relatively fixed beam horizontal extension and move.The frame for movement enabling this connected mode has varied, and the present invention does not have particular/special requirement to it simultaneously, all can meet above-mentioned needs for example, sleeve type, buckle-type and guide tracked etc. be suitable for the application and use；Equipped with walking beam retraction locking device on fixed cross beam 10, walking beam retraction locking device can lock to the retraction state of walking beam.The walking beam retraction locking device of this example is mainly made up of electric magnet 8, lock hook 9 and lock 12.Lock hook is hinged on fixed cross beam 10, and the ferrum 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 electric magnet 8, and electric magnet 8 is installed with fixed cross beam 10.When moved cross beam retraction, lock hook just catches on the lock 12 on moved cross beam, and walking beam is pinned.When electric magnet 8 is connected to computer unlocking instruction and during adhesive, lock hook 9 departs from lock 12, and walking beam can freely stretch out.As shown in Figures 2 and 3.
The walking beam of this example stretches out driving means and is mainly made up 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, walking beam is just protruding under the action of the spring, completes driving of task.
In order to be able to make walking beam bear shock, fixed beam is also equipped with walking beam and stretches out locking device.The state of stretching out that walking beam stretches out locking device lockable walking beam meets shock.The walking beam of this example stretches out locking device and mainly includes the composition such as lock hook 3, hinge 5, support 6 and spring.A hole is had, lock hook 3 may pass through this hole and moveable longitudinal beam 11 is caught on locking on end position when the corresponding moveable longitudinal beam 11 of fixing longeron 2 stretches out.Lock hook 3 is hinged on the frame 6 by hinge 5, and support 6 is fixedly mounted on fixing longeron 2, and equipped with spring on hinge 5, spring makes lock hook 3 press to the direction of moveable longitudinal beam.Once walking beam is protruding, lock hook just locks it.
Stretch out when walking beam needs, when not needing, retraction collection, does not thus increase the overall length of automobile.It is done so that produce a new problem it is simply that how to make walking beam can stretch out when needed again.For this.The present invention installs range unit on automobile, and range unit connects computer, and computer connects walking beam retraction locking device.Accurate judgement is made according to the data that range unit transmits by blas by computer.
In order to protect passenger inside the vehicle from the injury of instantaneous impact, this example protecting device for spring equipped with folding and unfolding between fixed beam and walking beam, main inclusion crossbeam receiver 13 and spring 14.Protecting device for spring is linked together with walking beam driving means, receives driving synchronization with walking beam, when walking beam stretches out, crossbeam receiver 13 release spring 14, and during walking beam retraction collection, spring 14 returns in receiver 14.The protecting device for spring of the application does not have special requirement; enable this connected mode frame for movement have varied; the present invention does not have particular/special requirement to it simultaneously, all can meet above-mentioned needs for example, sleeve type, buckle-type etc. be suitable for the application use.The former length of spring needs more than or equal to longeron length, with suitably long a little just permissible.This principle is very simple, spring has elasticity, compressible when receiving compressing, and this is an elastic process, so, the speed of two thing movements can be buffered moment when automobile is collided with foreign object, slow down rapidly impact dynamics, and lack spring and only have the collision hindering bar, the impulsive force producing in the moment of collision is very big, although walking beam serves cushioning effect, this is the effect within a bit of time, and the moment that can not collide again plays a role.Compared to the active protective device not having spring, add that the protection of protecting device for spring is more efficient.
The work process of the present invention：It is that retraction is collected and locked by walking beam retraction locking device, as shown in figures 1 and 3 under walking beam normal condition.At this moment spring 4 is in tensioning arm-to-arm；Automobile in the process of moving, range unit constantly measure this car with above（Before this device is contained in）The distance of barrier., the data transfer recording to computer, computer is by the relative velocity of these data reduction cost cars and above barrier for range unit.Computer processes these data by blas.Work as data display, Ben Che reaches the degree of danger of program setting with the above relative velocity of barrier and air line distance.For example when relative velocity be more than 10 kilometers/hour, air line distance be less than 2 meters when, computer just sends unlocking instruction to electric magnet 8, allows walking beam freely to stretch out.Adhesive after the electric magnet 8 of walking beam locking device receives the instruction of computer is unlocked, and lock hook 9 departs from lock 12, and walking beam, under the driving of walking beam driving means, is shot out under the driving of spring 4, and meanwhile, release spring opened by the crossbeam box of walking beam.When walking beam reach be returned to intermediate point after stop when, the lock hook 9 that walking beam stretches out on locking device just locks moveable longitudinal beam 11, it can not be decorporated afterwards again and withstands shocks, as shown in Figure 2 and Figure 4.
The definition of above-mentioned degree of danger depends primarily on the response time of system, and the time required for wherein walking beam stretches out is crucial.For guaranteeing safety, before colliding, walking beam must be protruding.Under various circumstances, computer system can survey out different data, obtain the different response time, make accurate judgement, feed back to the outreach of walking beam, moveable longitudinal beam can be set to the longeron of multistage difference thin and thick and size simultaneously, different bore holes can also be opened in multistage, each section of moveable longitudinal beam so can be enable all to have different mechanical strengths, so that moveable longitudinal beam is deformed in order rather than whole piece flexural deformation.So it is greatly improved anti-collision effect.
The four direction that the present invention can be contained in automobile is the shock of this four direction of Initiative Defense in the side of front, rear, left and right.No matter installing in which direction, as long as the instantaneous distance coupled computer installing the rammer that range unit measures this direction in a respective direction just can realize active anticollision and protection.
