Specific embodiment

For the technical characterstic place that the present invention will be described in detail, hereby lift following preferred embodiment and coordinate schema explanation such as Afterwards, wherein：

As shown in Figures 1 to 5, a kind of motor module 10 that first preferred embodiment of the invention is provided, mainly by one Shells 11, a lower shell 21, a drainage box 31 and a motor part 41 are formed, wherein：

An accommodating space 211 is formed with after the lower shell 21 and the top casing element 11 are combined.

The drainage box 31 is installed on the lower shell 21 and positioned at the lower section of the lower shell 21, and has in the drainage box 31 One Discharging blades 33.

The motor part 41, arranged on the accommodating space 211, which there is a rotor 42, a stator 43, one to drive 46 and two bearing 48 of moving axis, but not comprising a upper cover 13 and a lower cover 23, which is installed on the stator 43, the drive shaft 46 are arranged on the rotor 42, which is located in the drainage box 31 and connects the Discharging blades 33；Two bearing 48 is set In the drive shaft 46 and it is located at the stator and rotor 43,42 over and under.

This first preferred embodiment by two bearing 48 with oiliness bearing, then exemplified by coordinating two oil-containing sponges 49.Therefore, should Top casing element 11 has more a upper cover 13, which is located at the bottom of the top casing element 11；The lower shell 21 has more a lower cover 23, The lower cover 23 is located at the top of the lower shell 21, and the material of the upper and lower shells 11,21 is plastics, and the upper and lower cover 13,23 Material be metal.The motor part 41 have more a upper mounted plate 44 and a bottom plate 45, the upper mounted plate 44 and should Bottom plate 45 is respectively arranged on the both sides up and down of the stator and rotor 43,42, and is passed through by the drive shaft 46；The upper cover 13 and this under Lid 23 is equipped with an annular snap wall 53 towards the upper mounted plate 44 and the bottom plate 45 respectively；The upper mounted plate 44 and the bottom plate 45 have protruded out a ringwall 51 to the upper cover 13 and the lower cover 23 respectively；The upper and lower fixing plate 44,45 is by the ringwall 51 with combination The annular snap wall 53 of the upper and lower cover 13,23；Wherein, the bore that respectively the annular snap wall 53 is formed is more than the respectively ringwall 51 and is formed Bore, so as to providing the upper and lower cover 13,23 tight fits the upper and lower fixing plate 45.The upper mounted plate 44 can be corresponded to reference on this Lid 13 simultaneously forms subspace R1 on one, which can correspond to reference to the lower cover 23 and form subspace R2, the drive 46 one end of moving axis reconnects the Discharging blades 33 in the drainage box 31, the other end position of the drive shaft 46 by the lower subspace R2 In subspace R1 on this；Two bearing 48 is located at the subspace R1 and lower subspace R2 on this respectively.And each oil-containing sponge 49 The subspace R1 and lower subspace R2 on this is filled in respectively and is contacted with the respectively bearing 48.Wherein, which should Upper cover 13 and the lower cover 23 joint form a complete motor.

The structure of the first preferred embodiment of the invention is explained above, the assembling of first embodiment of the invention will be illustrated next State.

The motor module 10 of first preferred embodiment of the invention is when assembling, by the top casing element 11 and the motor part 41 Top is combined, at this point, the annular snap wall 53 of the upper cover 13 can be solid to reach with 51 tight fit of ringwall of the upper mounted plate 44 It is fixed；Then, then by the lower shell 21 and the bottom of the motor part 41 it is combined, the annular snap wall 53 of the lower cover 23 is with being somebody's turn to do 51 tight fit of ringwall of bottom plate 45 is to reach fixation；Finally, then by the drainage box 31 lower section of the lower shell 21 is assembled in, Complete the assembling of the present invention.Whereby, the upper cover 13 and the lower cover 23 i.e. can be combined with the motor part 41 and combine composition One complete motor.

Accordingly, the present invention can be arranged on the bottom of the top casing element 11 by the upper cover 13 and the lower cover 23 is arranged on the lower casing The top of part 21, then coordinate the combination of the upper mounted plate 44 and bottom plate 45 of the motor part 41, assembly program can be simplified, had Effect promotes assembling speed, has convenience.

In addition, compared to the prior art, the present invention is again by the upper cover 13 under the bottom of the top casing element 11 and this Lid 23 is arranged on the technical characteristic at the top of the lower shell 21, can effectively reduce metal shell and plastics described in the prior art The distance of shell, and then the effect of diminution motor volume.

But in addition, also the bore that respectively the annular snap wall 53 is formed can be set smaller than the mouth that respectively ringwall 51 is formed Footpath, so as to providing the upper and lower cover 13,23 tight fits the upper and lower fixing plate 44,45；It follows that by different assembling forms But can also it reach the effect of identical.

Then, coordinate again shown in Fig. 4 referring again to Fig. 6, a kind of motor mould that the second preferred embodiment of the invention is provided Block 10 ' is roughly the same with the structure of the first preferred embodiment, the difference is that：

It refers to shown in Fig. 6, this second preferred embodiment is by two bearing 48 ' by taking ball bearing as an example.Originally second preferably In embodiment and be not provided with the upper cover 13 and the lower cover 23, when this is due to the use of ball bearing, that is, be not required the upper cover 13 and Caused by the lower cover 23.Therefore in the upper cover 13, the lower cover 23, the upper mounted plate 44 and the bottom plate in assembling, can be omitted 45 setting (please coordinate shown in Fig. 4)；Whereby it is known that the motor module 10 ' of the second preferred embodiment of the invention coordinates not With form bearing, can also have effects that simplified assembly program and diminution motor volume, in industry and using On all have convenience.

Remaining structure of this second preferred embodiment and the effect of reaching, are generally same as preceding first preferred embodiment, therefore appearance The present invention is no longer repeated.

Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe Various corresponding changes and deformation, but these corresponding changes and deformation can be made according to the present invention by knowing those skilled in the art The protection domain of the claims in the present invention should all be belonged to.
