Description

Compact anti-displacement automobile fan

Technical Field

The invention relates to an automobile fan, in particular to a compact anti-displacement automobile fan.

Background

Along with the development of automotive industry, it is increasingly big to car driving space demand, and the car fan is the important part of carrying cold wind and hot-blast to the car in, original primary structure includes motor and wind wheel, motor and wind wheel respectively occupy a position space, consequently be difficult to give the vacation space in the car again, the wind wheel cover is in the pivot of motor simultaneously, lean on the tight connection of expanding between it, in case the tight degree of expanding not enough can make the wind wheel very easily take place the contact with the motor frame after touching, influence the normal work of wind wheel.

Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide a compact anti-displacement automobile fan that occupies a small space and prevents the displacement of a wind wheel.

In order to realize the purpose, the invention provides the following technical scheme: the utility model provides a compact prevents car fan that shifts, includes motor frame, motor and wind wheel, the motor is installed on the motor frame, has the pivot on the motor, the middle part of wind wheel is equipped with the trepanning, and the trepanning closely overlaps and establish the pivot tip, pivot tip position be equipped with the keyway, be equipped with assorted parallel key with it in the keyway the flat key terminal surface epirelief be equipped with spacing lug, the terminal surface of trepanning is close to or the butt is on spacing lug, be equipped with the confession on the motor frame the sleeve of motor installation, the motor is installed on this sleeve, the motor is whole stretch into to in the inner chamber of wind wheel extend the mounting panel that the symmetry set up on the sleeve perisporium, the mounting panel stretches out from the wind wheel and is used for the installation fixed.

The inner wall of the downward end part of the key groove is provided with a sunk groove, the end part of the flat key extends out of an inserting strip matched with the sunk groove, and the inserting strip is inserted in the sunk groove.

And chamfering the two sides of the end part of the flat key respectively.

One end of the wind wheel is provided with an inward-bent bowl-shaped cover, the bottom surface of the bowl-shaped cover is provided with a straight thickened bottom, the trepanning is arranged on the thickened bottom, and the motor is completely positioned in the bowl-shaped cover.

According to the structure, after the motor is positioned in the wind wheel, the space structure of the motor and the wind wheel is effectively reduced compared with the existing structure, a larger space can be vacated for the driving space in a vehicle, the comfort of the vehicle is improved, the limiting bump on the flat key can effectively prevent the wind wheel from shifting to the motor frame, the touch risk of the wind wheel is avoided, the structure is more reliable, and the technical effects of small space occupation and wind wheel shifting prevention are achieved.

The invention is further described with reference to the following figures and detailed description.

Drawings

FIG. 1 is a perspective view of an embodiment of the present invention;

fig. 2 is an enlarged view of a in fig. 1.

Detailed Description

The following examples are provided to illustrate the present invention and should not be construed as limiting the scope of the invention.

As shown in fig. 1 and fig. 2, the embodiment discloses a compact anti-displacement automobile fan, which includes a motor frame 1, a motor 2 and a wind wheel 3, the motor 2 is installed on the motor frame 1, a rotating shaft 21 is provided on the motor 2, a sleeve hole 31 is provided in the middle of the wind wheel 3, the end of the rotating shaft 21 is tightly sleeved with the sleeve hole 31, a key groove 4 is provided at the end of the rotating shaft 21, a flat key 5 matched with the key groove 4 is provided in the key groove 4, a limit bump 51 is convexly provided on the end surface of the flat key 5, the end surface of the sleeve hole 31 is close to or abutted against the limit bump 51, a sleeve 10 for installing the motor 2 is provided on the motor frame 1, the motor 2 is installed on the sleeve 10, the motor 2 completely extends into an inner cavity of the wind wheel 3, mounting plates 11 symmetrically provided extend out of the circumferential wall of the sleeve 10, and the mounting plates 11 extend out of the wind wheel 3 for installation and fixation.

A sunk groove 41 is arranged on the inner wall of the downward end part of the key groove 4, an inserting strip 52 matched with the sunk groove 41 extends out of the end part of the flat key 5, and the inserting strip 52 is inserted in the sunk groove 41. The structure can ensure that the matching of the flat key 5 and the key slot 4 is more compact and reliable, prevent the flat key 5 from separating from the key slot 4 and improve the compactness of the whole structure.

And chamfering treatment is respectively carried out on two sides of the end part of the flat key 5 so as to facilitate the flat key 5 to be placed in the key groove 4, and the operation is more convenient and reliable.

One end of the wind wheel 3 is provided with an inward bent bowl-shaped cover 32, the bottom surface of the bowl-shaped cover 32 is provided with a straight thickened bottom 33, the trepanning 31 is arranged on the thickened bottom 33, and the motor 2 is completely positioned in the bowl-shaped cover 32. The circumferential wall of the sleeve hole 31 is thicker and thicker through the structure, and the telescopic performance of the sleeve hole 31 is reduced, so that the rotating shaft 21 and the sleeve hole 31 are more closely and reliably inserted and matched, and the displacement of the wind wheel 3 can be further prevented.

Through the technical scheme, be located motor 2 back in wind wheel 3, make motor 2 and wind wheel 3's spatial structure compare effective reduction with current structure, can vacate great space for the space of driving in the car, improve the travelling comfort that the vehicle used, and spacing lug 51 on the flat key 5 can prevent effectively that wind wheel 3 from shifting to motor frame 1 department, the touching risk of wind wheel 3 has been avoided, make the structure more reliable, just so reached the space occupy for a short time and prevent the technological effect that wind wheel 3 shifted.
