  • the anti-collision performance of existing motor vehicles is significantly worse than the anti-collision performance, which is the main reason for the high mortality rate of rear-end collisions.
  • U.S. Patent No. 3,797,872 discloses the installation of a piston propulsion energy absorbing mechanism at both the front and the rear of the motor vehicle.
  • a reducing valve is installed between the front piston cylinder and the connecting pipe, and is also installed between the rear piston cylinder and the connecting pipe.
  • the diameter reducing valve when the front part collides, the front impact rod will move backward with the piston through the piston rod, and the backward moving piston will force the fluid pressure in the piston cylinder to increase, and the pressurized fluid will pass through the contraction.
  • the radial valve is sprayed at high speed into the connecting pipe. Due to the throttling effect of the reducing valve, there is a huge pressure difference between the reducing valve front and rear, which will generate a backward thrust.
  • This backward thrust will cause the connecting pipe to be squeezed. That is to say, the vehicle body is in a compressed state.
  • the motor vehicle When the collision speed is high, the motor vehicle will be severely deformed, and even the front passengers and passengers may be squeezed to death.

  • the connecting pipe due to the throttling effect of the reducing valve, there is a huge pressure difference before and after the reducing valve, which will generate a forward thrust, which will cause the connecting pipe to be squeezed, that is, the machine The body of the motor car is in a compressed state.
  • the motor vehicle When the collision speed is high, the motor vehicle will be severely deformed and may even crowd the rear passengers. That is to say, the patented vehicle body is always in a compressed state during the collision, i.e. the patent does not ensure that the motor vehicle body is stretched during the collision.

Energy and piston energy consumers to consume.
  • the patent has the following problems: 1 During the collision, due to the participation in the injection The number of nozzles is constant. The test results show that the speed curve of the motor vehicle body is half sinusoidal. The piston advances about 2/3 of the distance and has consumed 92% of the kinetic energy of the motor vehicle. The remaining 1/3 of the distance consumes only 8% of the machine. The kinetic energy of the moving car is manifested by the excessive liquid pressure peak in the tubular stringer and the high peak of the vehicle body acceleration.
  • the reduction of the pressure peak and the reduction of the acceleration peak are the problems to be solved. 2
  • the motor vehicle body may be in a compressed state. This is because when the front collision occurs, the front piston has protruded into the bottom of the front piston cylinder. At this time, a rear-end collision occurs.
  • the front piston will also move forward at the same time. The reset process of the front piston is hardly consumed. Any energy, the pressure of the liquid in the tubular stringer can not be established. At this time, the nozzle type energy consuming device and the piston type energy consuming device cannot function.
  • the motor vehicle body may be severely crushed and deformed, and even the occupant may be Squeeze casualties.
  • the advancement distance of the front piston ram may be greater than the design distance.
  • the collision rod will directly impact the piston cylinder end cover, which will cause the motor vehicle body to be in a compressed state. May cause casualties. 4 Regardless of whether it is a 100% full frontal collision or a 70% offset collision, the number of nozzles participating in the injection is constant, and it is impossible to satisfy both 100% full frontal collision and 70% offset collision.
  • the left and right front pistons connected to the front impact bar in 100% full frontal collision are involved in absorbing energy, and the volume of liquid available for injection is the sum of the volumes of the two piston cylinders.
  • the two pistons each bear half of the collision force, so the pressure in the tubular stringer is low, because the injection speed is proportional to the one-half of the pressure, which results in a low liquid injection speed, in the case of the same number of nozzles.
  • the volume of liquid ejected is too small; and when 70% of the offset collisions, only one piston is involved in absorbing energy, and the volume of liquid that can be ejected is only the volume of one piston cylinder, compared to only one piston at this time to bear all the collision forces.
  • the pressure inside the tubular stringer is large, and the liquid jetting speed is large.
  • the volume of the liquid ejected in the case of the same number of nozzles is excessively large, which may cause the automobile body to be crushed and deformed, and even cause casualties.
  • the number of nozzles participating in the injection is constant, which is not conducive to optimizing the anti-frontal collision design and the anti-collision collision design. 6
