A first embodiment of the invention is illustrated by the following:
in the figures, 1 and 2 are split structures, wherein a fixed block connecting rod 5 and a rope leading fixed block 33 are both arranged on the side wall of a bumper 1, before a car accident happens, a pressure extrusion block 35 is clamped inside an extrusion block through groove 37, a clockwork spring 311 is in a deformation state, a cutting rotating block 36 rotates for a circle in the process that the clockwork spring 311 recovers to deform, and a buffer spring 3 is in a maximum compression state initially;
as can be seen from fig. 2 and 3, when a small car accident occurs, at which a light impact occurs to the bumper 1, the bumper 1 begins to dent toward the end of the front support plate 2;
as can be seen from fig. 4, the bumper link 34 pushes the pressure-pressing block 35 to press the pressing cover plate 310, the extrusion cover plate 310 clamped with the cutting rotating block 36 is separated from the cutting rotating block 36 under the extrusion action, when the pressure extrusion block 35 is pushed to be not contacted with the extrusion block through groove 37 completely, the cylindrical end of bumper link 34 enters the interior of the squeeze block channel 37 and, since the clockwork spring 311 is initially in a compressed state, when the buckling force disappears, the cutting rotating block 36 starts to rotate, so as to drive the cutting sheet 39 to cut the pull plate guide rope 32 on the rotating path, the buffer spring 3 which is in the initial compression state supports and buffers the bumper 1 through the buffer plate 31 in the process of restoring the deformation, therefore, the supporting protection of the bumper 1 under the low-intensity collision is achieved, and the large maintenance problem in the case of small car accidents is avoided;
from what is described herein, it can be seen that: the invention realizes the supporting and buffering functions to the bumper 1 under the condition of small collision by the matching action among the internal components of the buffering and supporting device and the extrusion force generated during collision and the cutting action of the cutting piece 39 on the pull plate rope 32, thereby achieving the double supporting functions when traffic accidents happen or not.
A second embodiment of the invention is illustrated by the following:
as can be seen from fig. 3 and 9, when a small car accident occurs, since the pressure slide bar 22 slowly moves towards the inside of the slide bar box 21, and the solution pressure inside the liquid outlet rotary block 42 is smaller than the elastic force of the blocking spring 49, the centrifugal force approaches to 0, so that the hydrochloric acid solution inside the liquid outlet rotary block 42 does not flow out;
as can be seen from fig. 8 and 9, since the anticorrosion inner ring is arranged inside the liquid outlet rotary block 42, the stored hydrochloric acid will not volatilize and corrode the liquid outlet rotary block 42 due to the sealing function;
as can be seen from fig. 5 and 6, when a large car accident occurs, which is an instant process, the buffer plate 31 also supports the bumper 1 as mentioned in the first embodiment, but only performs decompression due to large impact force, the pressure slide bar 22 moves into the slide bar box 21 in the process, and the solution inside the liquid outlet pipe 46 is centrifuged due to the engagement between the middle part of the liquid outlet driving bar 41 and the side wall of the driving groove 4 during the movement of the pressure slide bar 22 due to large pressure, the liquid outlet driving bar 41 rotates too fast;
as can be seen from fig. 9, the solution subjected to the centrifugal action starts to squeeze the inner liquid outlet plate 48 to compress the blocking spring 49, and due to the abutting action of the liquid outlet pipe 46, the blocking elastic plate 410 is opened, so that the hydrochloric acid solution flows out through the liquid outlet pipe 46;
as can be seen from fig. 7, since calcium bicarbonate is stored in the gas generation tank 44, when hydrochloric acid reacts with calcium bicarbonate, gas is instantaneously generated, and the generated gas is subjected to the inflation process in the cushion airbag 45, so that the damage of the interior of the automobile engine cavity is reduced by the cushion effect of the cushion airbag 45 in the inflated state;
from what is described herein, it can be seen that: according to the invention, through the cooperation between the inflation protection device and the buffer support device, the rapid inflation work of the buffer air bag 45 is realized by utilizing the centrifugal force and the reaction action, so that the protection function of the front engine cavity is realized when a large car accident happens.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
