Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
A kind of DC brushless motor of the high-protection level of the utility model, as shown in Figs. 1-2, including housing body components 1,
Armature spindle 2, rear end cap 3, drive end bearing bracket 4 and connecting line export connector 5, and armature spindle 2 is mounted in housing body components 1,3 He of drive end bearing bracket
Rear end cap 4 is mounted on the both ends of housing body components 1, and armature spindle 2 is mounted on drive end bearing bracket 3 and rear end cap 4 by bearing, connecting line
Export connector 5 is mounted on housing body components 1, and rear end cap 4 includes ontology 43 and lid 42, and lid 42 is mounted on ontology 43,
The side that drive end bearing bracket 3 and rear end cap 4 install housing body components 1 is provided with protrusion 6, and opens up the first installation in raised 6 side walls
Sealing ring 7 is installed in slot 31 and the second mounting groove 41, the first mounting groove 31 and the second mounting groove 41.When the electricity of the utility model
Machine is placed on the outdoor on rainy day, and rainwater may flow into from drive end bearing bracket 3, rear end cap 4 and 1 connecting sewing of housing body components, in seam
Rainwater, to flowing down, if excessive rainfall, only cannot exclude rainwater by flowing down along protrusion 6, rainwater can flow into the
In one mounting groove 31 and the second mounting groove 41；At this point, the first mounting groove 31 and the second mounting groove 41 are equivalent to guiding gutter, by rain
Water is guided to lower section, the interior discharge of connecting sewing from below；And prevent rainwater from entering in housing body components 1 by sealing ring 6.It is logical
Cross the first mounting groove 31 and the second mounting groove 41 and the entrance for cooperating sealing ring 6 that can effectively prevent water；Certainly, the structure
Also it can be carried out effective dust-proof.
In one embodiment, the mounting hole interference of connecting line export connector 5 and housing body components 1 is arranged.With this configuration,
It effectively prevent water and dust to enter in housing body components 1 from mounting hole.
In one embodiment, connecting line exports connector 5 and opens up third mounting groove downwards with being bonded for housing body components 1
51, and sealing ring 6 is set in third mounting groove 51.Firstly, connecting line export connector 5 is fitted closely with housing body components 1,
Play first step water proof and dust proof；Secondly, installing sealing ring 6 in third mounting groove 51, water proof and dust proof is further functioned as.Most
Afterwards, it is arranged by the mounting hole interference that connecting line exports connector 5 and casing assembly 1, final step water proof and dust proof is played, by upper
Structure is stated, water proof and dust proof grade is substantially increased.
In one embodiment, ontology 43 is equipped with 42 side of lid setting step structure, and in the side of step and upper
Face opens up the 4th mounting groove 44 and the 5th mounting groove 45 respectively, and sealing ring 6 is installed in the 4th mounting groove 44.When water pours
When the motor of the utility model, most water flows away on the outside of lid 42, only small part water from lid 42 and ontology 43 it
Between gap flow into, but these water first flow into the 5th mounting groove 45, are equivalent to one cushion chamber of water supply, the 5th mounting groove 45
Interior water flow to lower section, and gap outflow from below, and the 4th mounting groove 44 is in addition arranged and sets in the 4th mounting groove 44
Sealing ring 6 is set, firstly, still playing guiding role to water in the 4th mounting groove 44, only below by water guiding；In addition, passing through
Sealing ring prevents water from entering in housing body components 1, by above structure, reduces the pressure of sealing ring, increases its leakproofness
Can, improve service life.
In the above-described embodiments, sealing ring 6 is nitrile rubber sealing ring.
It can be sent out compared to existing water proof and dust proof mode since the utility model uses the sealing ring with toughness
Raw deformation, when motor air pressure inside is excessive, meeting be discharged between sealing ring and mounting groove, and then reduce motor air pressure inside.But
Due to the toughness of sealing ring, its leakproofness is still ensured that.
The above is only the preferred embodiments of the utility model, are not used to limit the scope of the utility model；If
The spirit and scope for not departing from the utility model, are modified or replaced equivalently the utility model, should all cover in this reality
In novel scope of protection of the claims.
