[0024] The utility model provides a composite material buffer energy absorption device, comprising a buffer energy absorption seat 1, a first buffer box 6, a buffer plate 10 and a composite material body 26, the buffer energy absorption seat 1 is fixed to the outer wall of the composite material body 26 by bolts, a guide rod 2 is arranged inside the buffer energy absorption seat 1, and a buffer block 3 is slidably connected inside the buffer energy absorption seat 1, and the buffer block 3 is slidably sleeved on the outside of the guide rod 2, a buffer spring 1 4 connected to the buffer block 3 is arranged on the inner wall of the buffer energy absorption seat 1, and the buffer spring 1 4 is sleeved on the outside of the guide rod 2, and buffer springs 2 5 are arranged on the outer walls facing each other of the two buffer blocks 3, a rear plate 7 is arranged on the rear side of the first buffer box 6, and a connecting block 1 8 is fixed to the outer wall of one side of the rear plate 7 by bolts, a connecting block 2 27 is arranged on the outer wall of one side of the buffer block 3, and the connecting block 1 8 is rotatably connected to the inner part of the connecting block 27 by a rotating shaft with a rotating block 9, and an extrusion block 11 is fixed to the outer wall of one side of the buffer plate 10 by bolts, The extrusion block 11 is slidably inserted into the interior of the first buffer box 6, and a buffer airbag 12 is placed inside the first buffer box 6, and the buffer airbag 12 contacts the extrusion block 11 and the rear plate 7 respectively. When the composite material body 26 is extruded or collided, the buffer plate 10 will drive the extrusion block 11 to squeeze the buffer airbag 12. The buffer airbag 12 can buffer and absorb the extrusion and collision force of the buffer plate 10 for the first time, and buffer and absorb the extrusion or collision force for the first time.

The extrusion force or collision force is buffered and absorbed twice, and the buffering energy absorption effect is better.
[0025] By setting: the buffer airbag 12 can provide the first buffer for the collision or extrusion force received by the buffer plate 10, and then the buffer plate 10 will push the first buffer box 6 to move toward the buffer energy absorption seat 1, which will drive the connecting block 1 8 to move toward the buffer energy absorption seat 1 to displace the connecting block 2 27, and the connecting block 2 27 will drive the buffer block 3 to move, and the elastic force of the buffer spring 1 4 and the buffer spring 2 5 can buffer the buffer block 3, thereby absorbing and buffering the collision or extrusion force received by the buffer plate 10, and the two bufferings can achieve better buffering energy absorption effect.
[0026] In one embodiment provided by the present utility model, Figure 2 and Figure 3 As shown, a movable cavity 13 is opened inside the buffer energy absorbing seat 1, and a movable plate 14 is slidably connected inside the movable cavity 13. A return spring 17 connected to the movable plate 14 is arranged on the inner wall of the movable cavity 13. An insertion rod 15 is integrally connected to the outer wall on one side of the movable plate 14. The pulling force of the return spring 17 can pull the movable plate 14 and the insertion rod 15 to move.
[0027] In another embodiment provided by the present utility model, Figure 2 and Figure 3 As shown, both ends of the guide rod 2 are provided with insertion holes 16 , and the insertion rod 15 is inserted into the insertion holes 16 to fix the guide rod 2 .
[0028] In another embodiment provided by the present utility model, Figure 1 , 2 and Figure 3 As shown, a supporting block 18 is inserted on the outer wall of one side of the buffer energy absorbing seat 1, and the supporting block 18 is inserted into the inside of the movable cavity 13. The supporting block 18 moves to press the inclined surface of the movable plate 14 to move the movable plate 14.
[0029] In one embodiment provided by the present utility model, Figure 2 and Figure 3 As shown, a slide plate 19 is slidably connected to the inside of the supporting block 18, and an insert block 20 is integrally connected to the outer wall of one side of the slide plate 19. A slot 21 is opened on the inner wall of the movable cavity 13, and the insert block 20 is inserted into the inside of the slot 21 to fix the supporting block 18.
[0030] In another embodiment provided by the present utility model, Figure 2 and Figure 3 As shown, fixing springs 23 are welded on the outer walls of the two slide plates 19 facing each other, and a push block 22 extending to the outside of the supporting block 18 is provided on the outer wall of one side of the slide plate 19, through which the slide plate 19 and the insert block 20 can be pushed to move.
[0031] In another embodiment provided by the present utility model, Figure 2 and Figure 4 As shown, a replacement screw 24 penetrates the internal thread of the rear plate 7, and a threaded hole 25 is provided on the outer wall of one side of the first buffer box 6. The replacement screw 24 is threadedly inserted into the threaded hole 25, so that the rear plate 7 can be fixed on the first buffer box 6.
[0032] Working principle: The buffer energy absorption seat 1 is installed on the outer wall of the composite material body 26 by bolts. When the composite material body 26 is squeezed or collided, the buffer plate 10 will drive the extrusion block 11 to squeeze the buffer airbag 12. The buffer airbag 12 can buffer and absorb the extrusion and collision force of the buffer plate 10 for the first time, and then the first buffer box 6 will drive the connecting block 1 8 to move toward the buffer energy absorption seat 1. Because the connecting block 1 8 is connected to the connecting block 2 27 by the rotating block 9 and the rotating shaft, when the connecting block 1 8 moves toward the buffer energy absorption seat 1, the rotating block 9 will push the connecting block 2 27 to move, and the connecting block 2 27 will drive the buffer block 3 to squeeze the buffer spring 1 4. At this time, the buffer spring 2 5 will stretch, and the elastic force of the buffer spring 1 4 and the buffer spring 2 5 can buffer the buffer block 3, so that the buffer plate 10 can absorb and buffer the collision or extrusion force. The two buffering can achieve better buffering energy absorption effect. When the device is used for a long time When the energy storage of the rear buffer spring 14 or the buffer spring 25 is not good, the two push blocks 22 are squeezed to drive the slide plate 19 to move. The slide plate 19 will drive the plug block 20 to move, so that the plug block 20 can be moved out from the inside of the slot 21, and the supporting block 18 is pulled toward the outside of the buffer energy absorption seat 1. At this time, the movable plate 14 is not squeezed by the supporting block 18, and the pulling force of the pull-back spring 17 will pull the movable plate 14 and the plug rod 15 to move, so that the plug rod 15 is moved out from the inside of the socket 16, and the buffer block 3 and the guide rod 2 are pulled toward the outside of the buffer energy absorption seat 1, and the guide rod 2 can be removed from the buffer energy absorption seat 1, and the buffer spring 14 and the buffer spring 25 can be replaced. When the air of the buffer airbag 12 is insufficient, the replacement screw 24 is threaded out from the inner thread of the threaded hole 25 to separate the rear plate 7 from the first buffer box 6, and the buffer airbag 12 can be replaced, which can ensure that the device is in a good buffer energy absorption state to avoid the phenomenon of poor buffer energy absorption effect, thereby improving reliability.
[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
