Abstract
The invention discloses an impact testing device of an automobile seat. The impact testing device of the automobile seat comprises a testing table, a stand column, a pendulum rod and a pendulum. The stand column is fixed on the testing table, the upper end of the pendulum rod is hinged on the upper portion of the stand column through a shaft, and the pendulum is fixed on the lower end of the stand column. The pendulum is formed by a pendulum body, a counterweight block, a stiffness adjustment mechanism and a punch mechanism. The stiffness adjustment mechanism is composed of a piston rod, a spring and a counterweight block, a step hole is arranged at the center of the pendulum body, a spring is arranged at the rear end of the step hole, the piston rod is arranged at the front end of the step hole and the front portion of the counterweight block is connected withthe rear end of the step hole in a threaded mode. The punch mechanism is formed by a ball head rod and a punch head, the rod portion of the ball head rod is connected inside the piston rod in a threaded mode, and the punch head and the ball head portion of the ball head rod form a rotating pair. The impact testing device of protecting board of automobile seat can simulate a comprehensive action effect of size, direction and acting time of the action force of a safe belt to a protecting board during a front impacting process.
Description
Technical field
The present invention relates to a kind of test unit, particularly a kind of automotive seat backplate impact test apparatus.
Background technology
In the front impact test of automobile, securing band has an impulsive force to the automotive seat backplate, and this impulsive force crashes the automotive seat backplate sometimes.In the driving process of reality, if the situation of automotive seat backplate fragmentation occurs, the automotive seat backplate fragment that splashes can be hurted sb.'s feelings.So, require the automotive seat backplate to satisfy the standard that is not crashed by the impulsive force of securing band.In addition, in the front impact test of automobile, if the automotive seat backplate is crashed by the impulsive force of securing band, then this time test is failed, carry out test next time, and the expense of each test needs about 60,000 yuans.If before carrying out the front impact test of automobile, the automotive seat backplate is simulated impulse test, then can reduce the risk of the front impact test failure of automobile, reduce the expense of the front impact test of automobile.
Summary of the invention
The purpose of this invention is to provide a kind of automotive seat backplate impact test apparatus, hit in the process securing band before the simulation to the action effect of automotive seat backplate.
The present invention is made of testing table, column, fork and pendulum, and column is fixed on the testing table, and the upper end of fork is hinged on the top of column by axle, and pendulum is fixed on the lower end of column; Described pendulum is comprised of hammer body, balancing weight, stiffness tuning mechanism and plunger mechanism, stiffness tuning mechanism is comprised of piston rod, spring and balancing weight, the center of hammer body offers shoulder hole, spring is positioned at the rear end of shoulder hole, piston rod is positioned at the front end of shoulder hole, and the front portion of balancing weight is screwed onto the rear end of shoulder hole; Plunger mechanism is to be made of ball rod and impact head, and the bar section of ball rod is screwed onto in the piston rod, and impact head is combined with the ball head of ball rod and is formed revolute pair.
Described column has fluting, and axle is fixed on the coupling block, and coupling block and fixed block sandwiched column pass the fixed block coupling block that is spirally connected with bolt, axle is fixed on the column height that this kind structure can regulating shaft.
Described fork is to be made of upper boom and lower beam, and lower beam is plugged in the slot of upper boom hypomere, and the fluting that bolt passes the upper boom hypomere is screwed onto with the screw of lower beam, and bolt is fixed together upper boom and lower beam, and this kind structure can be regulated the length of fork.
The present invention can simulate impulse test to the automotive seat backplate by the swing of fork and pendulum.
Beneficial effect of the present invention:
1, column can carry out the height adjusting according to the length of fork.
2, fork has length regulation function; Pendulum has quality by the increase and decrease balancing weight and adjusts function; Stiffness tuning mechanism has rigidity and adjusts function, and so, the impact initial velocity, the impact energy that make the present invention can control percussion mechanism reach the action time to backplate, can satisfy different impulsive force requirements.
3, plunger mechanism has certain rotating function, makes drift have a plurality of action directions.
4, hit in the process securing band before adopting experimental provision of the present invention effectively to simulate to the combined action effect of size, direction and the action time of backplate acting force.
