Leaf spring structure and suspension structure
View Patent ↗A leaf spring structure includes at least two leaf springs, a leaf spring connecting component, two first lifting ears, and two second lifting ears. The at least two leaf springs overlap in a vertical direction, and the at least two leaf springs decrease in length gradually from bottom up. The at least two leaf springs include a first leaf spring and a second leaf spring. The first leaf spring is longer than the second leaf spring. The leaf spring connecting component is configured to fixedly connect body portions of the at least two leaf springs in a length direction. The two first lifting ears are respectively disposed at two first free ends of the first leaf spring in the length direction, and the two second lifting ears are respectively disposed at two second free ends of the second leaf spring in the length direction.
1 . A suspension structure, comprising:
a leaf spring structure comprising:
at least two leaf springs, wherein:
the at least two leaf springs overlap in a vertical direction;
the at least two leaf springs decrease in length gradually from bottom up; and
the at least two leaf springs comprise a first leaf spring and a second leaf spring, the first leaf spring being longer than the second leaf spring;
a leaf spring connecting component configured to fixedly connect body portions of the at least two leaf springs in a length direction;
two first lifting ears respectively disposed at two first free ends of the first leaf spring in the length direction; and
two second lifting ears respectively disposed at two second free ends of the second leaf spring in the length direction;
a steering knuckle assembly directly connected to the first lifting ears; and
a shock absorber assembly directly connected to the second lifting ears.
2 . The suspension structure according to claim 1 , wherein the at least two leaf springs have equal width.
3 . The suspension structure according to claim 1 , wherein the first leaf spring is disposed at a lowest part of the leaf spring structure.
4 . The suspension structure according to claim 3 , wherein the second leaf spring is disposed above the first leaf spring.
5 . The suspension structure according to claim 1 , wherein the second leaf spring and the first leaf spring are adjacent to each other.
6 . The suspension structure according to claim 1 , wherein the second leaf spring and the first leaf spring are spaced apart from each other.
7 . The suspension structure according to claim 1 , wherein:
the first lifting ear and the first leaf spring are integrally formed; and/or
the second lifting ear and the second leaf spring are integrally formed.
8 . The suspension structure according to claim 1 , wherein the first lifting ear and the second lifting ear are circularly or elliptically curved.
9 . The suspension structure according to claim 1 , wherein in the length direction, the two second lifting ears are located between the two first lifting ears.
