Alternatively, a plurality of springs 3 are connected successively and/or are in parallel.That is to say, a plurality of springs 3 can be connected successively, or 3 parallel connections of a plurality of spring, or some spring 3 series connection in a plurality of spring 3, other spring 3 parallel connections.
Particularly, take body 1 is connected in body 201 as example and describes by two springs 3.Wherein, when 3 series connection of two springs, these two springs 3 need to meet:
Wherein, k
1and k
2be respectively two spring 3 rigidity, the rigidity that k is bump leveller.
When two springs 3 are in parallel, these two springs 3 need to meet:
k=k
1+k
2
Wherein, k
1and k
2be respectively two spring 3 rigidity, the rigidity that k is bump leveller.
Preferably, spring 3 is two, and the two ends of body 1 are connected in body 201 by two springs 3 respectively.With reference to Fig. 1, the two ends, left and right of body 1 are connected in body 201 by two springs 3 respectively, and body 1 can move up at right and left.Alternatively, the equal stiffness of these two springs 3.
For example, in the example of Fig. 1, limit spatial accommodation in body 201, cylinder 202 is located in spatial accommodation and is positioned at the bottom of spatial accommodation, and bump leveller is located in spatial accommodation and is positioned at the top of cylinder 202, and the two ends, left and right of body 1 are connected in body 201 by two springs 3 respectively.
