On bumper 6；That is, the side of the second buffer cell 2 is in contact with bumper 6, can be with the deformation of bumper 6
Performed relative motion in the first buffer cell 1.
Spring 3, spring 3 is located between the first buffer cell 1 and the second buffer cell 2.That is, spring 3 realizes
Buffering between one buffer cell 1 and the second buffer cell 2, when bumper 6 deforms, makes the second buffer cell 2 in phase
When making contractile motion to the first buffer cell 1, spring 3 can give the second buffer cell 2 and make to deviate from the effect of the first buffer cell 1
Power.
Cushion pad 5, cushion pad 5 is located in spring 3, and its one end is suitable to be fixedly connected with the first buffer cell 1, and its is another
End extends through spring 3 to the second buffer cell 2.That is, cushion pad 5 is horizontally arranged in spring 3, its right-hand member is suitable to support
It is pressed on the first buffer cell 1, so impulsive force can be further buffered when spring 3 makees contractile motion, but also can
To play a part of protecting spring 3, it is to avoid its transition is shunk and is damaged.
When vehicle hits, bumper 6 deforms in the presence of impulsive force, the second buffer cell 2 is transported to the right
It is dynamic, and then the spring 3 being located between the second buffer cell 2 and the first buffer cell 1 is also made contractile motion to the right, in this process
In, contractile motion is made by spring 3, the impulsive force produced during vehicle collision can be effectively absorbed, with the second buffer cell 2 by
Gradually move right, the left side wall of the second buffer cell 2 can be in contact with cushion pad 5, and cushion pad 5 can further slow down impact
Power, can also protect the effect of spring 3, it is to avoid spring 3 is damaged, and the apparatus structure is simple, safe and reliable.
In one embodiment of the invention, as shown in Fig. 1~Fig. 2, the first buffer cell 1 include relative left end edge and
