As shown in fig. 3, which is a top view of the metal film 2, it can be seen from fig. 3 that the protruding structures 23 are disposed around, and a spacing area 24 is formed between two adjacent protruding structures 23, and in the direction of the arrow in fig. 3, that is, the direction from the center of the metal film 2 to the edge, since the metal film 2 takes a shape of a protruding dome during the protruding process of the metal film 2 toward the gas storage space 112, the extension degree of different positions of the metal film 2 is different, and in order to ensure that the problem of local fatigue or breakage of the metal film 2 does not occur in the case that the extension degree of different positions of the metal film 2 is different, the width of each spacing area 24 is different. Of course, the width of the spacing region 24 gradually decreases in the direction of the arrow pointing.
As shown in fig. 4 and 5, each of the convex portions 231 in the same convex structure 23 is the same size; that is, it is stated that the problem of stress concentration does not occur in each of the projected structures 23, and when the metal film 2 is deformed as a whole, the stress at the position of each of the projections 231 in one of the projected structures 23 is substantially the same, so that the occurrence of stress concentration at a position of a certain projection 231 is effectively avoided.
Of course, since the metal film 2 assumes a convex dome shape during the projection of the metal film 2 toward the air storage space 112, the degree of expansion of the metal film 2 at different positions is different when the metal film 2 is projected, and the place where the tension on the metal film 2 is the greatest is at the vertex position of the film. This is because the curvature of the metal film 2 is greatest at the apex, and the tension is proportional to the curvature. Therefore, the vertex position of the metal film 2 is the place where the tension is the greatest. The corresponding protrusions 231 of the protruding structures 23 at different positions are different in size, i.e. the protrusions 231 in any protruding structure 23 are different in size, and of course, for better stress, the protrusions 231 in the protruding structure 23 near the center of the metal film 2 are larger, i.e. the protrusions 231 in the protruding structure 23 are larger compared to the protrusion at the center of the metal film 2. That is, the size of the convex portion 231 in the convex structure 23 sequentially becomes smaller from the center of the metal film 2 toward the edge direction.
In fig. 4, a protrusion 23 is disposed on one side of the first surface 21 or the second surface 22 of the metal film 2, and in fig. 5, a protrusion 23 is disposed on both sides of the first surface 21 or the second surface 22 of the metal film 2.
As shown in fig. 6, the shape of each boss 231 in the same projection structure 23 is the same as that of fig. 6, compared to fig. 4, that is, the shape of the boss 231 in the projection structure 23 is changed. Of course, the shape of the convex portion 231 in any one of the convex structures 23 is different, for example, the shape of the convex portion 231 of the convex structure 23 near the center of the metal film 2 may be a polygonal structure in fig. 4, and then the shape of the convex portion 231 of the convex structure 23 far from the center of the metal film 2 may be a circular arc shape in fig. 6.
The shape of the convex portion 231 is not particularly limited as long as the convex portion 231 in the same circle of the convex structure 23 can be ensured to be the same in shape, for example, the shape of the cross-sectional area of the convex portion 231 in the direction of the first surface 21 toward the second surface 22 is polygonal, for example, the polygonal shape may be trapezoidal, rectangular, or the like; alternatively, the cross-sectional area of the boss 231 is circular arc-shaped in a direction in which the first surface 21 is directed toward the second surface 22.
With continued reference to fig. 5, when the first surface 21 and the second surface 22 are each provided with a plurality of protruding structures 23, and when the pressure of the liquid storage space 111 and the air storage space 112 are the same, the first surface 21 and the second surface 22 are parallel, and the protruding portions 231 of the protruding structures 23 on the first surface 21 are disposed in one-to-one correspondence with the protruding portions 231 of the protruding structures 23 on the second surface 22. Since the movement direction and the protruding direction of the metal film 2 are limited by the pressures of both the liquid storage space 111 and the gas storage space 112, when the pressure of the liquid storage space 111 is greater than the pressure of the gas storage space 112, the metal film 2 protrudes toward the gas storage space 112; when the pressure of the liquid storage space 111 is smaller than the pressure of the gas storage space 112, the metal film 2 protrudes toward the liquid storage space 111, so that it can be determined that the metal film 2 reciprocates in two directions, and therefore, the first surface 21 and the second surface 22 of the metal film 2 are formed with the protruding structures 23, ductility of the first surface 21 and the second surface 22 of the metal film 2 is ensured, and service life and ductility of the metal film 2 are greatly improved.
As shown in fig. 7 and 8, in order to improve the ductility of the whole metal film 2, the performance of the protruding structure 23 is extremely important, and there are various indexes of consideration for the ductility of the metal film 2: for example, elongation, which refers to the ratio of the length that a metal can extend during stretching to the original length; the higher the elongation, the better the ductility of the metal. For example, elongation at break refers to the ratio of the cross-sectional area of the metal before breaking to the cross-sectional area after breaking. For example, plastic strain refers to the amount of strain of a metal during plastic deformation. The greater the plastic strain, the better the ductility of the metal. For example, fracture toughness refers to the energy that a metal is able to absorb before breaking. The higher fracture toughness indicates the better ductility of the metal. For example, bending properties, which refer to the ability of a metal to bend during bending; the better the bending properties, the better the ductility of the metal. In order to at least increase the ductility of the metal, the protrusion 231 has a structure conforming to at least two different materials, and the protrusion 231 includes a filling portion 2312 and a coating 2311 coating the filling portion 2312, and the protrusion 231 has a composite structure, and the material of the coating 2311 is different from that of the filling portion 2312. The coating 2311 may be a stainless steel layer for corrosion protection and strength improvement, and the filling 2312 may be tin, zinc, magnesium, or the like for ductility improvement.
Of course, in order to further improve the ductility of the metal film 2, the elongation of the wrapping layer 2311 is greater than the elongation of the filling portion 2312.
