Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is that flat fronted car bumps against schematic diagram.
Detailed description of the invention
The present invention is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of forward flat automobile anti-collision system as shown in Figure 1 to Figure 3 comprises car body 13, girder 2 on car body 13, and the stopper 1 of car body 13 front portion, wherein, also comprise the auxiliary beam 3 be located at and car body 13 is connected with described stopper 1, between this auxiliary beam 3 and described girder 2, there is a buffer gear arranged along automobile working direction.
The girder that girder 2 in the present invention can directly use flat fronted car to carry, or the girder carried at automobile is outer or interior retightening again arranges car beam to serve as girder 2, and this girder 2 is fixed on one with the car body 13 of automobile; And auxiliary beam 3 is connected with the stopper 1 of automobile.When automobile and other automobile or fixture collide, move toward one another between two between girder 2 and auxiliary beam 3, cushioned by the buffer gear be arranged between girder 2 and auxiliary beam 3, make that the impact force that is delivered on auxiliary beam 3 by automobile stopper 1 is weak on this buffer gear successively decreases, when being passed to girder 2, this impact force is decremented to zero, or is decremented to minimum, reach the crashworthiness of car body 13 postmedian, that is to say car load crashworthiness.
When automobile is in normal traveling or working process, described buffer gear should be locked, namely inoperative.The present invention is connected with a lockout mechanism 7 on described auxiliary beam 3, this lockout mechanism 7 is arranged a trigger mechanism 11, and this trigger mechanism 11 connects with radar ranging velocity measurement mechanisms 12 signal in automobile stopper 1.Particularly, described lockout mechanism 7 is a kinematic mechanism be connected with a joggle by tooth bar tooth bar with described auxiliary beam 3, and when tooth bar tooth bar engages each other, described auxiliary beam 3 is by this lockout mechanism 7 stationary positioned, and then make buffer gear inoperative, ensure the normal effect of car body 13.When the described buffer gear work of needs, need the tooth bar engagement on described lockout mechanism 7 to separate, make auxiliary beam 3 be in free state.Described trigger mechanism 11 connects with radar ranging velocity measurement mechanisms 12 signal in the stopper 1 being located at automobile, distance between automobile with other obstacle and the relative speed of a motor vehicle is monitored by this radar ranging velocity measurement mechanisms 12, value according to setting controls trigger mechanism 11, makes lockout mechanism 7 be in unlock state.Described trigger mechanism 11 can mechanically, also can by hydraulic way, can also be triggered by modes such as electromagnetism, in this example, this lockout mechanism 7 is the pole being provided with hinging fulcrum in the middle part of in the of, and the vertical orientation of described lockout mechanism 7 away from one end of tooth bar arranges a hydraulic cylinder to realize the trigger state of lockout mechanism 7.On this trigger mechanism 11 described lockout mechanism 7 opposite face on be also provided with a return unit, such as spring, realized the reset of lockout mechanism 7 by the tension force of spring or convergent force.
After automobile collision preventing function completes, in order to make whole automobile homing, the tooth bar of described auxiliary beam 3 has motor return mechanism 5, this motor return mechanism 5 drives auxiliary beam 3 to move to stopper 1 direction, that is to say and drive auxiliary beam 3 return, due to the existence of return unit tension force or convergent force, lockout mechanism 7 is resetted again with the tooth bar on auxiliary beam 3 and engages.
For between described girder 2 and auxiliary beam 3, in this example, be channel-section steel structure between this girder 2 and auxiliary beam 3, wherein auxiliary beam 3 port ons is located in girder 2.Described auxiliary beam 3 and/or stopper 1 are provided with a support blocking mechanism.This support blocking mechanism can be located at separately in stopper 1, also can be located at separately on auxiliary beam 3, or be located on stopper 1 and auxiliary beam 3, the Main Function of this support blocking mechanism avoids auxiliary beam 3 unrestrictedly to move to girder 2 direction simultaneously, thus destroy buffer gear.Therefore, described support blocking mechanism plays the buffer action of auxiliary buffer gear, stops stopper 1 and auxiliary beam 3 to move to girder 2 direction.This support blocking mechanism comprises the ratchet 6 with ground effects, and the relative movement portion connected between ratchet 6 and stopper 1 and/or auxiliary beam 3, this relative movement portion is tooth bar engaging mechanism, and this relative movement portion has the ratchet detent mechanism 9 and ratchet recovering mechanism 10 that are connected with described ratchet 6.This ratchet 6, ratchet detent mechanism 9, ratchet recovering mechanism 10 are similar with the principle of work of aforementioned lockout mechanism 7, trigger mechanism 11, motor return mechanism 5, then this does not carry out repeating to set forth.
Described buffer gear comprises the buffer cell 4 of multiple series connection and/or parallel connection, and this buffer cell 4 comprises and the hinged spring perch 41 of described auxiliary beam 3, and the spring 42 be connected with described girder 2, this spring 42 is located in described spring perch 41.During concrete enforcement, by a strut bar and auxiliary beam 3 chain connection, be connected in the end of strut bar spring perch 41, and described spring 42 is equipped with spring perch 41, and spring 42 also can be connected by a strut bar or be hingedly connected on described girder 2.Wherein, when multiple buffer cell 4 is arranged in series, be connected on the spring 42 of another buffer cell 4 with the spring perch 41 of a buffer cell 4 by strut bar, multiple buffer cell 4 successively head and the tail connects, and the correspondence respectively at its two ends is arranged on auxiliary beam 3, girder 2.In fitting process, buffer cell 4, arranging along positive and negative in automobile working direction, does not affect the buffer capacity of buffer cell 4.And multiple buffer cell 4 is when being arranged in parallel, be connected with auxiliary beam 3, girder 2 respectively by each buffer cell 4 two ends.Also can be arranged in parallel again after multiple buffer cell 4 series connection simultaneously, or be arranged in series again after multiple buffer cell 4 parallel connection.
In actual application, can also also arrange radar ranging velocity measurement mechanisms to monitor position between vehicle afterwards at the tailstock of automobile, effectively can weaken the collision that rear-end collision occurs.
When automobile is about to collide, as shown in Figure 3, the corresponding speed of a motor vehicle and spacing is monitored by the radar ranging velocity measurement mechanisms 12 in automobile stopper 1, carry out determining danger signal according to setting value, signal connects trigger mechanism 11 and starts, activated locking mechanism 7 is for the unblock of auxiliary beam 3, make buffer gear normal operation, when car collision, the stopper 1 of automobile will be subject to violent collision, impact force is passed to auxiliary beam 3 by stopper 1, decayed by buffer gear again, combine simultaneously and support blocking mechanism to the auxiliary counteracting of impact force, make the impact force being finally passed to girder 2 will decay to zero or decay to minimum, thus reach the crashproof of whole flat fronted car.
Above the technical scheme that the embodiment of the present invention provides is described in detail, apply specific case herein to set forth the principle of the embodiment of the present invention and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the embodiment of the present invention; Meanwhile, for one of ordinary skill in the art, according to the embodiment of the present invention, detailed description of the invention and field of application all will change, and in sum, this description should not be construed as limitation of the present invention.
