Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
Fig. 1-Fig. 2 is the structural schematic diagram of existing design, and amplification is identical in Fig. 5, the difference is that seal groove
Design.
Referring to Fig. 3-Fig. 5, new-energy automobile electronic water pump sealing structure, including, electronic water pump 100, on electronic water pump 100
It is provided with clamping cap 110, disengaging water cover 120, shell 130, the disengaging water cover is for passing through water flow, therefore, Inlet and outlet water
Sealing effect between lid 120 and shell 130 can directly affect the performance of electronic water pump；
It is provided on the disengaging water cover 120 and compresses card slot 121, it is convex that described 110 one end of clamping cap is provided with compression
Platform 111, the other end are the first compression end 112, are provided with seal groove, and shell 130 and the first compression end on the shell 130
112 corresponding positions are provided with the second compression end 131；Seal groove is assembled with sealing ring 210, thus by disengaging 120 end face of water cover and outside
Clearance seal between 130 end face of shell；210 section of sealing ring is circle；
The seal groove, including, half-arc groove 133, straight trough 132, the half-arc groove 133 to straight trough 132 away from
It is D2 from the length for D1, the straight trough 132, the sum of the D1 and D2 are equal to or more than sealing ring cross-section radius of circle, and
D1 is greater than D2.After shell 130 and disengaging water cover 120 are fastenedly connected by screw 310, sealing ring 210 can deform, and be higher than
The part of upper surface of outer cover, which can be crushed, fills up the vacant part in seal groove two sides, on the one hand this structure can guarantee electronic water pump
Sealing performance, while also can be reduced shell, sealing ring and disengaging water cover assembly between stress.
Preferably, the radius of 210 section of sealing ring circle is equal with 133 radius of half-arc groove, this is allowed for outside sealing ring 210
Side is bonded assembly completely with half-arc groove 133.In assembly, the part that only do not assemble with half-arc groove 133 deforms, from
And erection stress is reduced, and this design can also greatly increase sealing performance.
Preferably, cooperation seal groove 113 is provided on the inside of clamping cap 110, the disengaging water cover 120 is packed into cooperation sealing
In slot 113, and screw 310 is assembled with shell 130 after clamping cap 110 and is fixed, so that clamping cap 110 will pass in and out water cover
120 compress to shell 130.This design, which can be avoided, covers aperture in Inlet and outlet water, thus save the cost, and assemble more square
Just, the required precision for manufacture is also reduced.
Due in actual use, being sealed only according to sealing ring 210, the requirement of high pressure, Er Qieyi is sometimes not achieved
Denier sealing ring aging can seriously reduce its sealing performance.And sealing ring oxidation is mainly due to itself and air or corrosive liquids
Contact causes, and therefore, applicant is improved as follows:
Referring to Fig. 6, the clamping cap 110 is provided with sealing cover 114, second pressure at the first compression end 112
Tight end 131, disengaging 120 end of water cover are packed into sealing cover 114, and are fixed with sealing ring 220 on the inside of sealing cover 114, described
Sealing ring 220 on be respectively arranged with fixed part 221, the first sealing inclined-plane 222, seal convexity 223, the second sealing inclined-plane
224, the fixed part 221 is fixed on 114 end face of sealing cover, first sealing inclined-plane 222, the second sealing inclined-plane
224 outsides are adhesively fixed on 114 inside of sealing cover, and the setting of seal convexity 223 is close in the first sealing inclined-plane 222, second
Seal 224 intersection of inclined-plane；
The protrusion triangular in shape of seal convexity 223, and 131 end of the second compression end is provided with the first cooperation
Sealing inclined-plane 135, first compresses inclined-plane 134, and 120 end of disengaging water cover is provided with the second cooperation sealing inclined-plane 122, the
Two compress inclined-plane 123；
The first cooperation sealing inclined-plane 135 and the first sealing inclined-plane 222 are adjacent to sealing, the second cooperation sealing inclined-plane
122 and second sealing inclined-plane 224 compress seal, first compression inclined-plane 134, second compress inclined-plane 123 be pressed on respectively sealing it is convex
Play 223 two sides.This design between shell 130, disengaging 120 end face of water cover so that form close respectively in 114 inside of sealing cover
Envelope, and form second in shell 130 and disengaging 120 end face joint place of water cover and seal, and is oblique due to offering the first compression
Face 134, second compresses inclined-plane 123, so that it will not obviously increase shell 130 and pass in and out the erection stress between water cover 120,
Sealing ring, the erection stress at seal groove, leakproofness are not interfered with.
Other first sealing inclined-plane 222, the second sealing inclined-plane 224 are heeling condition, and from the first compression end 112 to
114 thickness of sealing cover is gradually thinning.This is allowed in assembly, and sealing ring 220 will not be under pressure and slide, to guarantee close
Sealing property.And edge sealing is formed by sealing ring, shell 130 can be effectively improved and passes in and out the sealing between water cover
Property, while improving sealing ring service life.
Referring to Fig. 7, the difference with Fig. 6 is, is not provided with the second sealing inclined-plane 224, and this design is more suitable assembly,
And leakproofness not decreased significantly, from cost control for, this design cost is relatively low.Later period convenient disassembly, and it is right
Leakproofness influence is not high, can be using in mass production.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
