Position or position relationship be based on orientation shown in the drawings or position relationship, be for only for ease of description the present invention and
Simplify description, rather than indicate or imply that the device or element of indication must be with specific orientation, with specific
Azimuth configuration and operation, therefore it is not intended that limiting the scope of the invention.
As shown in Figures 3 to 5, the electromotor oil baffle in present embodiment includes body 1, outside body 1
The edge of profile is provided with press section 2 towards outside extension, and the press section 2 is used to be pressed to oil by engine cylinder-body
The top end face of drain pan.During installation, press section 2 is placed in the corresponding position of the top end face of oil sump, then
Engine cylinder-body is placed on into the upper surface of press section 2 and is alignd with the bolt hole on oil sump, in bolt hole
In be put into bolt and tighten, what electromotor oil baffle now was relied on is between oil sump and engine cylinder-body
Thrust be fixed, therefore present embodiment eliminate on engine cylinder-body arrange with electromotor gear oil
The corresponding bolt hole of plate, so as to increase the intensity of engine cylinder-body, this contributes to improving the reliability of electromotor
Property, additionally, eliminating the operation such as processing bolt hole and stubborn bolt in processing and dismounting.
Preferably, press section 2 than body 1 thickness of thin, as can be seen from the figure：Press section 2 is interval
It is distributed in several support lug structures at the edge of the outline of body 1, then between two adjacent support lug structures
Gap can provide space for the bolt connection between engine cylinder-body and oil sump.
As shown in figure 4, the electromotor oil baffle in present embodiment also includes auxiliary elastic member 3, bullet is aided in
Property part 3 be located at the surface that press section 2 contacts with oil sump 5, for provide by press section 2 be expressed to send out
Elastic force on motivation cylinder body 7.That is, when press section 2 is pressed to oil sump by engine cylinder-body 7
When on 5, auxiliary elastic member 3 has elastic force and is shortened by release conditions and store elastic force, and the bullet
Property power increase with being pressed further by between engine cylinder-body 7 and oil sump 5, wait stop extruding, should
Elastic force is upward expressed to press section 2 on engine cylinder-body 7.Preferably, if auxiliary elastic member 3 includes
Dry rubber substance post, each rubber column is spaced apart.
As shown in figure 5, the electromotor oil baffle in present embodiment also includes keeper 4, keeper 4 sets
At the edge of the outline of body 1, and oil sump 5 can be matchingly joined to limit the electromotor gear oil
Degree of freedom of the plate relative to oil sump 5 in the horizontal plane, so as to prevent the electromotor oil baffle from saving spiral shell
Jumping in the horizontal plane in the case of bolt is fastened.Preferably, keeper 4 includes cylindrical plag, and quantity can be with
It is multiple.Can also be other shapes of raised structures, as long as the electromotor oil baffle can be limited relative to institute
State oil sump degree of freedom in the horizontal plane.
Electromotor oil baffle in present embodiment also includes sealing member, and sealing member is located at press section 2 and starts
Between the contact surface of machine cylinder body and/or the oil sump.Sealing member can be rubber washer, in oil sump and
Rubber washer plays more preferable pressuring action when engine cylinder-body is compressed.Due to rubber deformability by force,
Minim gap can be fully filled up, during oil sump and engine cylinder-body are by bolt presses, it is ensured that
Oil sump, engine cylinder-body are contacted completely with electromotor oil baffle, more reliable so as to ensure electromotor oil baffle
Fastened.
As shown in figure 8, electromotor is operationally, the machine oil in body is to recycle, to guarantee machine oil
Can return in oil return in oil sump 5, on the body 1 of oil baffle oil-through hole component is provided with.This enforcement
Mode arranges the oil-through hole component by certain rule, stockpiling on oil baffle during avoiding machine oil from flowing back
Amount is excessive, thus the inner engine oil amount of oil sump 5 is very few and affect the problem of the overall lubrication of body.
The oil-through hole component can include the first oil-through hole 11, and some first oil-through holes 11 are along body 1
Length direction is spaced apart, in view of body 1 is in convex structure, the first oil-through hole 11 is located at body 1
Lowest point, that is to say, that the first oil-through hole 11 is when body 1 is normally placed relative to the bottom of oil sump 5
Face is closest.Also, the position of the first oil-through hole 11 is corresponding with the position of bent axle, therefore, when using,
After lubricating oil on base bearing falls after rise, the first oil-through hole 11 can be directly over and flow back in oil sump 5.
The oil-through hole component can also include the second oil-through hole 12, the position of the second oil-through hole 12 and bent axle
The position of case is corresponding.Bent axle tank drainback just can the second oil-through holes of Jing 12 oil sump is returned within the shortest time
In 5.In addition, in order to ensure machine oil is dropped back in time, the opening of the second oil-through hole 12 is more than spill port.
The oil-through hole component can also include the 3rd oil-through hole 13, and some 3rd oil-through holes 13 are along body 1
Length direction be spaced apart, also, the position of the 3rd oil-through hole 13 is corresponding with the position of balance shaft,
So, the oil-through holes 13 of Jing the 3rd can be returned directly in oil sump 5 when falling after rise after oil lubricating balance shaft bearing.
Additionally, the oil-through hole component also includes the 4th oil-through hole 14, some 4th oil-through holes 14 are along body
1 length direction is spaced apart, and closes on the edge setting of body 1.Also, the 4th oil-through hole 14
Position is corresponding with the position of moving component.In present embodiment, every position for needing to lubricate all is motion
Position, machine oil must not be percent point when falling after rise vertically to be fallen after rise, and some can splash.Oil baffle avris,
Central side opens the 4th oil-through hole 14, and the oil-through holes 14 of machine oil Jing the 4th of splashing will be returned within the shortest time
To in oil sump 5.
As shown in fig. 7, the present invention also provides a kind of electromotor, including electromotor oil baffle, the electromotor
Oil baffle is the electromotor oil baffle described in above-mentioned embodiment.
As shown in Figure 6, it is preferable that the electromotor also includes oil sump 5, oil sump 5 starts with described
The contact surface of the press section 2 in machine oil baffle is provided with the first locating slot 6, and the first locating slot 6 can be matched
House press section 2, make the upper surface of press section 2 almost with the end face of oil sump 5, and then not shadow
Ring to the connection between engine cylinder-body 7 and oil sump 5.During installation, press section 2 is placed in into oil sump
In first locating slot 6 of 5 top end face, then engine cylinder-body 7 is placed on into the upper surface of press section 2,
And align with the bolt hole on oil sump 5, bolt is put in bolt hole and is tightened, using oil sump 5 and send out
Thrust between motivation cylinder body 7 is fixed to electromotor oil baffle.
Preferably, the electromotor also includes engine cylinder-body 7, and engine cylinder-body 7 keeps off with the electromotor
The contact surface of the press section 2 in oiled-plate method is provided with the second locating slot (not shown), second positioning
Groove can matchingly house the keeper 4 in the electromotor oil baffle, so as to further position described starting
Machine oil baffle, improves the connectivity robustness of the electromotor oil baffle.
The other parts of the electromotor are prior art, the not reinflated description of here.
It is last it is to be noted that：Above example only illustrating technical scheme, rather than to it
Limit.Although being described in detail to the present invention with reference to the foregoing embodiments, the ordinary skill people of this area
Member should be understood：It still can modify to the technical scheme described in foregoing embodiments, or right
