Description
Technical field
The present invention relates to automotive thermal tube reason system regions more particularly to a kind of rear covers of water pump and connection structure of outer shell, water
Pump and the automobile using the water pump.
Background technology
In automobile industry, the internal combustion engine equipped with booster needs to cool down air inlet in super charge end, generally
It is realized by electronic water pump circulating cooling liquid；At present, the electronic water pump of industry, rear cover are generally screw fastening, assembling with shell
When need to increase a sealing ring between, to ensure leakproofness, such as assemble it is insecure, be easy to cause water pump leak into
Water leads to the failures such as internal short-circuit, exists simultaneously the problems such as assembly technology is complicated, part is more, low production efficiency；Cost also compares
It is high；Therefore, solving the above problems just is particularly important.
Invention content
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of rear cover of water pump and connection structure of outer shell,
Water pump and the automobile using the water pump match to merge and are aided with weldering by annular groove and annular protrusion, conical protrusions and groove
Take over section so that water pump seamless is good and improving productivity, is sealed without multiple parts, reduces the manufacture of product
Cost.
The present invention provides a kind of rear cover and connection structure of outer shell of water pump, including pump shell and rear cover, outside the water pump
Shell is equipped with annular groove, and center is equipped with conical protrusions, and the rear cover is equipped with annular protrusion, and center is equipped with groove,
The conical protrusions of the pump shell are interference fit with the groove of rear cover center；The annular groove of pump shell is with after
The annular protrusion of lid is clearance fit, and the pump shell is internally provided with contact sensor, by contact sensor to rear cover
The degree of being installed in place be detected.
Further improvement lies in that：Fixed screw is provided on the pump shell, contact is provided in the pump shell
Gasket is detected, detecting make-up of the gasket to fixed screw by contact, situation is detected and buffers in place.
Further improvement lies in that：The material of the rear cover and pump shell uses polyphenylene sulfide and adds in the glass of %-% ratios
Glass fiber, rear cover are connected together with pump shell for ultrasonic bonding or vibration friction welding (FW) or laser welding.
Further improvement lies in that：The depth of the annular groove of the pump shell be less than rear cover annular protrusion height, two
The difference in height of person is 0.1-1.0mm.
The present invention also provides a kind of water pump, including above-mentioned pump cover and connection structure of outer shell.
The present invention also provides a kind of automobile, including above-mentioned water pump.
The beneficial effects of the invention are as follows：It is auxiliary with merging with groove by annular groove and annular protrusion, conical protrusions
With the means of welding so that water pump seamless is good and improving productivity, is sealed without multiple parts, reduces product
Manufacture cost, thus with good airproof performance, production efficiency is high, firmly install, assembly technology is simple, the advantageous effects such as at low cost.
