Therefore, the structural design is ingenious, and the durability of the elastic sheet assembly 100 is improved.

For example, as shown in fig. 1 and 3, in the front-back direction of the elastic sheets 3, the heights of the lower edges of the first pads 11 (the first pads 11 are not shown in fig. 3) in the up-down direction gradually decrease and then gradually increase, the heights of the upper edges of the second pads 21 in the up-down direction gradually decrease and then gradually increase, and the force-receiving positions of the elastic sheets 3 are not on a straight line, so that the force-receiving positions of the elastic sheets 3 are dispersed, and the service life of the elastic sheets 3 is prolonged.

Further, in a direction from one end of the elastic sheet 3 to the other end (in the direction, the other side edges of the first gaskets 11 are flush, and the heights of the first gaskets 11 are gradually reduced or gradually increased), and/or in a direction from one end of the elastic sheet 3 (for example, the upper end of the elastic sheet 3 shown in fig. 3) to the other end (for example, the lower end of the elastic sheet 3 shown in fig. 3), the other side edges of the second gaskets 21 are flush, the heights of the second gaskets 21 are gradually reduced or gradually increased, the upper edges of the first gaskets 11 are flush, the heights of the first gaskets 11 are gradually reduced or gradually increased in the up-down direction, in the up-down direction of the elastic sheet 3, the lower edges of the second gaskets 21 are flush, and the heights of the second gaskets 21 are gradually reduced or gradually increased in the up-down direction.

Therefore, the structure is simple, the stress positions of the elastic pieces 3 are dispersed, and the service life of the elastic pieces 3 is prolonged.

It should be noted here that the upper edge of the first gasket 11 is generally flush with the upper edge of the elastic sheet 3 or the upper edge of the first gasket 11 is higher than the upper edge of the elastic sheet 3, and the lower edge of the second gasket 21 is generally flush with the lower edge of the elastic sheet 3 or the lower edge of the second gasket 21 is lower than the lower edge of the elastic sheet 3, so as to avoid rigid contact between the end of the gasket and the elastic sheet 3, and improve the service life of the elastic sheet 3.

In some embodiments of the present invention, the other side edges of the plurality of first gaskets 11 are flush with each other in a direction from one end of the spring plate 3 (e.g., the upper end of the spring plate 3 shown in fig. 3) to the other end (e.g., the lower end of the spring plate 3 shown in fig. 3), and/or the other side edges of the plurality of second gaskets 21 are flush with each other in a direction from one end of the spring plate 3 (e.g., the upper end of the spring plate 3 shown in fig. 3) to the other end (e.g., the lower end of the spring plate 3 shown in fig.

That is to say, in the up-down direction of a plurality of shell fragments 3, can be the upside border parallel and level of a plurality of first gaskets 11, and the height of a plurality of first gaskets 11 risees gradually earlier and then reduces gradually or reduces gradually earlier and then risees gradually, also can be the downside border parallel and level of a plurality of second gaskets 21, the height of a plurality of second gaskets 21 risees gradually earlier then reduces gradually or reduces gradually earlier and then risees gradually, can also be the upside border parallel and level of a plurality of first gaskets 11, the downside border parallel and level of a plurality of second gaskets 21, when a plurality of first gaskets 11 highly risees gradually earlier and then reduces gradually or reduces gradually earlier and then risees gradually, the height of a plurality of second gaskets 21 risees gradually earlier and then reduces gradually or reduces gradually earlier and then risees gradually. Thus, the stress position of the elastic sheet 3 is dispersed, the rigid contact between the end part of the gasket and the elastic sheet 2 is avoided, the damage form of the elastic sheet assembly 100 is reduced, and the service life of the elastic sheet 3 is prolonged.

For example, as shown in fig. 3, in the up-down direction of the elastic sheets 3, the upper side edges of the first gaskets 11 (not shown in the figure) are flush, the lower side edges of the second gaskets 21 are flush, the heights of the first gaskets 11 are gradually increased and then gradually decreased, and the heights of the second gaskets 21 are gradually increased and then gradually decreased, so that the stress positions of the elastic sheets 3 are not on the same straight line, the stress positions of the elastic sheets 3 are dispersed, and the service life of the elastic sheets 3 is prolonged.

In one embodiment, the plurality of first pads 11 are symmetrically arranged and/or the plurality of second pads 21 are symmetrically arranged in the thickness direction of the plurality of spring pieces 2.

In some embodiments of the present invention, the height difference between two adjacent first gaskets 11 in the direction from one end of the elastic sheet 3 to the other end is not less than 1mm, and/or the height difference between two adjacent second gaskets 21 in the direction from one end of the elastic sheet 3 to the other end is not less than 1 mm. That is to say, the height difference between two adjacent first pads 11 in the direction from one end of the elastic piece 3 to the other end may be not less than 1mm, the height difference between two adjacent second pads 21 in the direction from one end of the elastic piece 3 to the other end may be not less than 1mm, or the height difference between two adjacent first pads 11 in the direction from one end of the elastic piece 3 to the other end may be not less than 1mm, and the height difference between two adjacent second pads 21 in the direction from one end of the elastic piece 3 to the other end may be not less than 1 mm. Therefore, stress concentration is reduced, and the service life of the gasket is ensured.

For example, as shown in fig. 3, the height difference of the lower edges of two adjacent first spacers 11 in the up-down direction is not less than 1mm, and the height difference of the upper edges of two adjacent second spacers 21 in the up-down direction is not less than 1mm, so that the manufacturing is facilitated, and the service life of the dome assembly 100 is ensured.
