The invention relates to the field of fans, in particular to an automobile fan structure and a fan sleeve thereof. The automobile fan sleeve includes a clamping outer cylinder, a clamping inner cylinder, an elastic strip, a motor shaft connector, and a positioning ring; the clamping inner cylinder is vertically arranged inside the clamping outer cylinder, and there is a gap between the clamping outer cylinder There is an installation gap, the outer wall of the clamping inner cylinder is provided with a stopper; the inner wall of the clamping outer cylinder is provided with a card slot; there are multiple elastic strips, each elastic strip is set on the upper end of the motor shaft connector, and along the motor shaft connector distributed uniformly in the circumferential direction; each elastic strip includes an elastic column and a buckle, each elastic column is arched outward, the lower end of the buckle is connected with the upper end of the elastic column, and the joint is hinged to the positioning ring, and the middle section of the elastic column is provided with a Protrusion: When the lower end of the clamping outer cylinder is in contact with the upper end of the motor shaft connector, the elastic column is inserted into the installation gap, the protrusion is inserted into the card slot, and the buckle is engaged with the stopper. The outward arching height of the elastic column is less than that of the elastic column The height of the outward arch when inserted into the mounting 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 by keys to rotate under the driving of the motor. This connection form is convenient and fast, but limited by the machining accuracy of the workpiece, it is easy to cause the fan sleeve to move axially, making the fan in the Noise is generated during rotation, which affects 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. SUMMARY OF THE INVENTION [0003] The present invention provides an automobile fan structure and its fan sleeve to solve the problem of unreliable axial connection of the existing fan sleeve. [0004] An automobile fan structure of the present invention and its fan sleeve adopt the followin...
