Specific embodiment, the present invention is further explained.
Referring to Fig. 1, the present invention provides a kind of preposition energy absorption device technical side of car for resetting chip resistant using air pressure
Case: its structure includes vehicle body 1, power device 2, preceding energy absorption device 3,
1 right end of vehicle body is fixedly connected with 2 left end of power device, is machine inside 1 right end of vehicle body and power device 2
Tool connection, 2 right end of power device are connected with preceding 3 left end of energy absorption device；The preceding energy absorption device 3 is by bumper system
31, it resets energy absorption device 32 to form, the 31 left end outer wall of bumper system is that card slot is connect with 2 right end of power device, described
31 left end of bumper system and 2 right end outer wall of power device are clearance fit, 32 right end of reset energy absorption device and bumper
31 left end left end of device is fixedly connected, and 32 left end of reset energy absorption device and 2 right end of power device are mechanical connection, the guarantor
Dangerous thick stick device 31 can reduce the damage of the knocked in car low speed impact.
Referring to Fig. 2, the bumper system 31 is made of memory thin plate 311, Crashworthy plate 312, the memory thin plate 311
Right end fits with 312 left end of Crashworthy plate, and 311 left end of memory thin plate is fixedly connected with energy absorption device 32 is resetted, the note
Recall thin plate 311 and use memorial alloy material, by external force after deformation occurs, original shape can be restored to, remember thin plate and anticollision
The combination of plate increases the feasibility restored after Crashworthy plate deformation, is difficult to restore after preventing Crashworthy plate from deforming, reduces integral replacing
Spending.
Referring to Fig. 2, the reset energy absorption device 32 is made of cystosepiment 321, spring lever 322, air pressure restorer 323,
322 right end of spring lever is connect with 321 left end of cystosepiment to be vertical, and 322 left end of spring lever and air pressure restorer 323 are right
End is mutually welded, and 321 right end of cystosepiment is connected with bumper system 31, and the cystosepiment 321 uses foam, is had
Certain cushion performance can reduce impact force, increase the transmitting distance of impact force, be effectively reduced the damage impacted to human body
Wound.
31 left end of bumper system is connected with 32 right end of energy absorption device is resetted, and the bumper system 31 is equipped with note
Recall thin plate 311,311 left end of memory thin plate is connected with power device 2, and the power device 2 is equipped with cystosepiment 321, institute
Memory 311 left end of thin plate is stated mutually to bind with 321 right end of cystosepiment.
Referring to Fig. 3, the air pressure restorer 323 is by fixed frame A, air hose B, telescopic rod C, pressure ball D, fixed link
E composition, the fixed frame A inner wall left end and the left end air hose B are to be tightly connected, the air hose B outer wall and fixed frame A
