Abstract
A fan frame structure includes a base portion and a wall portion. The base portion has at least one extension section vertically extended from an outer peripheral edge of the base portion, and the extension section has connecting sides. The wall portion is formed along the outer peripheral edge of the base portion through an insert molding process. The wall portion includes a plurality of wall segments connected to the connecting sides of the extension sections, and a clearance is formed between any two adjacent wall segments. With these arrangements, the base portion can better resist a wrapping force from the insert-molded wall portion to avoid deformation.
Claims8
A fan frame structure, comprising:
- a base portion having at least one extension section vertically extended from an outer peripheral edge of the base portion;
- and the at least one extension section having connecting sides provided thereon;
- and
- a wall portion being integrally formed along the outer peripheral edge of the base portion through insert molding and including a plurality of wall segments;
- and each of the plurality of wall segments being connected to the connecting sides of the at least one extension section, and a clearance of narrow slit shape formed between an outer edge of one wall segment and an opposite outer edge of an adjacent wall segment to fully cut a connection between the outer edge and the opposite outer edge of the two adjacent wall segments, the clearance providing sufficient expansion allowance for the plurality of wall segments and preventing any expansion of the insert molded wall portion to press against the base portion and deform the base portion.
A fan frame structure, comprising:
- a base portion having at least one extension section vertically extended from an outer peripheral edge of the base portion;
- and the at least one extension section having connecting sides provided thereon;
- and
- a wall portion being integrally formed along the outer peripheral edge of the base portion through insert molding and including a plurality of wall segments;
- the plurality of wall segments being connected to the connecting sides of the at least one extension section, and a recess formed between two adjacent wall segments of the plurality of wall segments and indented from an outer side of the two adjacent wall segments to an inner side of the two adjacent wall segments such that the recess provides sufficient expansion allowance for the wall segments and prevents any expansion of the insert molded wall portion to press against the base portion and deform the base portion.
