Abstract

The invention relates to the field of fans, in particular to an automobile fan structure and a fan sleeve thereof. The automobile fan sleeve comprises a clamping outer cylinder, a clamping inner cylinder, elastic strips, a motor shaft connector and positioning rings; the clamping inner cylinder is vertically arranged on the inner side of the clamping outer cylinder, an installation gap is reservedbetween the clamping inner cylinder and the inner wall of the clamping outer cylinder, and stop blocks are arranged on the outer wall of the clamping inner cylinder; clamping grooves are formed in the inner wall of the clamping outer cylinder; the elastic strips are all arranged at the upper end of the motor shaft connector and are uniformly distributed along the circumferential direction of themotor shaft connector; each elastic strip comprises an elastic column and a buckle, each elastic column is arched outwards, the lower end of each buckle is connected with the upper end of the corresponding elastic column, the joints are hinged to the positioning rings, and a protrusion is arranged on the outer side of the middle section of each elastic column; and when the lower end of the clamping outer cylinder makes contact with the upper end of the motor shaft connector, the elastic columns are inserted into the installation gap, the protrusions are clamped into the clamping grooves, the buckles are clamped to the stop blocks, and the outward arching height of the elastic columns is smaller than the outward arching height of the elastic columns when the elastic columns are not insertedinto the installation gap.

Description

technical field [0001] The invention relates to the field of fans, in particular to an automobile fan structure and a fan sleeve thereof. Background technique [0002] Most of the existing automobile fan sleeves are connected with the motor shaft through keys to rotate under the drive of the motor. Noise is generated during rotation, affecting the driving experience. Therefore, there is a need for an automobile fan structure that is reliably connected to the motor shaft to avoid axial movement of the fan sleeve. Contents of the invention [0003] The invention provides an automobile fan structure and its fan sleeve to solve the problem of unreliable axial connection of the existing fan sleeve. [0004] A kind of automobile fan structure and its fan sleeve of the present invention adopt following technical scheme: [0005] An automobile fan sleeve, comprising a clamping outer cylinder, a clamping inner cylinder, an elastic strip, a motor shaft connector, and a positionin...
