Compressing structure, power module and a method for compressing a component inside a chamber

A compressing structure for compressing a component, wherein the compressing structure is provided for compressing a component to a fixed plate, the compressing structure comprising:

• a plate-shaped structure, comprising a first surface and a second surface disposed opposite to each other, and a side surface connected between the first surface and the second surface, the component is fixed on the first surface of the plate-shaped structure and the plate-shaped structure is provided with a base on the outside;
• at least a steering compressing member is provided between the second surface of the plate-shaped structure and the base, and is mounted on the second surface of the plate-shaped structure or the base, the steering compressing member is provided for transforming an external rotational motion around a first rotation axis into a translational motion along a first direction, in which the first direction is perpendicular to the second surface of the plate-shaped structure, and the extension direction of the first rotation axis is perpendicular to the first direction;
• and
• at least a positioning device mounted on the side surface of the plate-shaped structure and the base, such that the plate-shaped structure has a degree of freedom of rotating around a second rotation axis relative to the base, the extension direction of the second rotation axis is a second direction perpendicular to the first direction.
