Abstract

The utility model relates to an electric fan motor, wherein the electric fan motor comprises an outer shell for mounting one end of fan blades and a fan net cover piece locked outside the shell, and one side of the fan net cover piece is designed to be a protruding columnar tube-shaped screw hole seat according to the position of the locking bolt, and each hole seat is connected to each other by a ring body of appropriate height to form a wall-shaped reinforcement ring, thereby ensuring the rigidity of use and simplifying the locking process when assembling the electric fan.

Description

Electric fan motor

The utility model relates to a kind of fan motor, relates in particular to a kind of structure improved fan motor.Described fan motor is the screw seat that the bearing cover plate by fan leaf one end directly is set as stator with lock, make must not lock in addition and adorn a motor case, can directly lock the dress fan leaf, make the structure assembling of whole motor seat easier easily, reach and save cost and shorten the purpose of assembling, making man-hour.

The cap combining structure of general fan motor mostly as shown in Figure 3, one stator 7 around full induction coil 73 is arranged, be arranged with a circular hole that runs through 72 in stator 7 four corners, and in the inner motor shaft 5 that cooperates installing one band round rotor 51 of stator 7 hollows, axis body is assembled according to the location that rotor 51 is installed in the stator 7, stretch out to both sides at two ends, wherein an end is by the motor outer end, cooperate lock to adorn an outer cover 6, lid 6 is with an end annulus 61 to fit with stator 7 one end faces and is assembled, and run through circular hole 72 or its relative position with respect to stator 7 four corners in end annulus 61, in lid 6 outwards protrude be crossed as that criss-cross arm post 63 or 61 both sides of end annulus are respectively equipped with that the lock assembling closes run through screw 60, in addition on arm post 63 outerplanars of bending, be provided with for shell (person of not drawing on the figure) lock dress screw 62, and in another avris of stator 7, with a lid shell 8 identical shaped with the set lid of opposite side 6, with set identical lock dress on the anchor ring with running through the lock screw 82 of dress cover plate 9 usefulness of screw 81 and arm post 83 and post, cooperation runs through both sides lid 6 with bolt 84,8 lock dresses, and in two lids 6, on 8 the outer shaft end face, for cooperating rotating shaft 5 to wear for stator 7, be respectively equipped with the axis hole 64 that installs for rotating shaft 5,85, rotating shaft 5 location are rotated, and be to make the assembling of motor case coat the lock dress in lid shell 8 outsides, one flat cover plate 9 is except that the center is provided with an axis hole 94 that installs for motor shaft 5, needs according to heat radiation and reinforcement, be designed to cover plate 9 bodies that surrounded by radial interval catch 91 and reinforcing ring 93 grades, and be provided with groove 92 frameworks that a combination shell is used in the housing of cover plate body, and intersect criss-cross catch 91 with respect to the position of screw 82 on the lid shell 8 arm posts 83 according to one group, cooperate and pass circular hole 95 with bolt 951 and lock dress and fix; With regard to the combining structure of integral body, the quite complicated structural design of can saying so not only uses member various, and making is difficult for and expends cost, more causes assembling to incur loss through delay waste man-hour, and the inconvenience in its use is arranged really.

Main purpose of the present utility model is shell and cover plate to be given one-body molded for overcoming above-mentioned the deficiencies in the prior art part, and assembled component is reduced, and makes that to make packaging technology easy easily, shortens assembling and reduces manufacturing cost man-hour.

Effective improvement of the utility model compounding ingredient material is used, electric fan is fanned the square sheet give particular design again, cover plate is locked the through hole position of dress on one side according to motor stator, established the column jecket that stays high protruding suitable height, this body end then is designed to a screw shape, supplies to cooperate with the direct sealed whole motor configuration of bolt, and between each column jecket, the continuous reinforcement of the reinforcement frame that centers on to link to each other makes to reach assembling simplification requirement.

Below in conjunction with accompanying drawing the utility model is elaborated.

Brief Description Of Drawings:

Fig. 1: be the stero exploded view of the utility model fan motor.

Fig. 2: be the combination appearance figure of the utility model fan motor.

Fig. 3: for commonly using the stero exploded view of fan motor.

See also Fig. 1, shown in 2, the main combined member of fan motor of the present utility model comprises: the stage casing that is assembled in the motor body, the motor stator 2 of winding induction coil 22 around square-shaped, in the central authorities of stator 2 be coated with one with induction coil 22 induction starts, central authorities are coated with the rotor 41 of rotating shaft 4, need according to the assembling locking, the angle is equipped with the circular hole 21 that runs through around stator 2, and when one side of stator 2 face cooperates assembling, one outer cover 1, its shape is roughly to commonly use outer cover similar, and has the arm post 14 of identical evagination and in order to the nose circle ring 11 of mutual applying winding lock dress be divided on the anchor ring and the screw 12 of arm post 14 outsides locking usefulness, 13 and in order to the assembling bearing group, the cover plate 3 that then cooperates special lock dress usefulness in stator 2 other ends, the inner side edge face of cover plate 3 lock dresses, remove groove 35 frames of tool engaging shell (not drawing on the figure) usefulness, outside shell body can being inserted connect airtight, on cover plate 3 whole faces, offer a central shaft hole 36 in middle position, be provided with in the axis hole 36 for 37 groups on the convex bearing of rotating shaft 4 bracing frames dress, rotating shaft 4 is stretched out to assemble the fan blade rotation, and for ask can be effectively directly interlocking be fixed in stator 2 one sides, and must not connect the lock dress by a middle lid as the fan motor of commonly using, lock with the relative positions that run through circular hole 21 according to stator 2 at cover plate 3 limit faces, one is installed with and protrudes the suitably column jecket 31 of height when cover plate 3 is one-body molded, and be equipped with one section screw 32 in the body end, for with stator 2 on run through circular hole 21 and align after, cooperation is penetrated stator 2 with one than stay bolt 34, the screw 12 of interlocking opposite side lid 1 is to assemble whole fan motor.

The utility model is with the fan motor end cover plate 3 that links to each other with fan blade, be designed to one and have special assembling column jecket 31 and lock dress screw 32, not only on the structure assembly working, can effectively save and align interlocking and generally cover shell 8 members, the other trouble of interlocking cover plate 9 again, (as shown in Figure 3), can shorten actual assembled man-hour significantly.And when making, integrated cover plate 3 structures of the utility model, the essence effect that the member of not only having assembling is simplified more can directly reduce the number of components, saves costs of manufacture such as material relatively.

In sum, fan motor of the present utility model not only with whole motor configuration assembling, is done suitable simplified design, can directly reduce cost of manufacture, and tool simple and convenient assembly practical effect.
