Description
Technical field
Electronic vacuum pump field is the utility model is related to, more particularly to a kind of exhaust structure of automotive electronics vacuum pump.
Background technology
For orthodox car, to meet the emission request of engine, the vacuum in the auxiliary booster of braking system obtains
Less than guarantee；And there is no vacuum source for motor vehicle driven by mixed power and pure electric vehicle, inside, case above is required for true by electronics
Sky pump compensates.
For the vane type electronic vacuum pump applied to automobile, when pump stopping moment, the negative pressure meeting that inside exhaust ports produce
Wet air or water are sucked, so as to condense out substantial amounts of water in pump body, vacuum pump performance is influenced, ultimately results in the pump housing
Failure.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of exhaust structure of automotive electronics vacuum pump, structure letter
It is single, solve the problem of pump housing stopping moment, the negative pressure that pump body produces sucks wet air or water.
Technical solution is used by the utility model solves its technical problem：A kind of row of automotive electronics vacuum pump is provided
Depressed structure, including motor flange and upper cover, the side of the motor flange is axially disposed exhausting-gas hole, the exhausting-gas hole it is upper
Hold it is coaxially arranged have unidirectional valve opening, be provided with the side wall of the upper cover extend downward into check valve hole site exhaust be oriented to
Hole, for the unidirectional valve opening interior axle to spring is provided with, the upper end of the spring is connected with block the lower end for being vented pilot hole
Ball sealer.
Supplemented as one kind to technical solution described in the utility model, the exhaust pilot hole is inclined to be arranged in
In the side wall of upper cover, the upper end of the exhaust pilot hole extends to the madial wall top of upper cover.
Supplemented as one kind to technical solution described in the utility model, the spring is big top and small bottom tower
Shape spring.
Supplemented as one kind to technical solution described in the utility model, the ball sealer is steel ball.
Further, the lower end of the exhaust pilot hole is disposed with the cone shaped opening to match with ball sealer.
Beneficial effect：A kind of exhaust structure of automotive electronics vacuum pump is the utility model is related to, it is simple in structure, pass through setting
Pilot hole and the steel ball unidirectionally opened are vented to realize one-way exhaust, the pump housing is solved and stops moment, pump body produces negative
The problem of pressure sucks wet air or water.
Brief description of the drawings
Fig. 1 is the half-sectional structure chart of main view of the utility model.
Reference numeral：1st, motor flange；2nd, upper cover；3rd, it is vented pilot hole；4th, ball sealer；5th, spring；6th, unidirectional valve opening；7、
Exhausting-gas hole.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It is to be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
Please the appended claims limited range.
As shown in Figure 1, the embodiment of the utility model is related to a kind of exhaust structure of automotive electronics vacuum pump, including electricity
Machine flange 1 and upper cover 2, the side of the motor flange 1 is axially disposed exhausting-gas hole 7, the coaxial cloth in upper end of the exhausting-gas hole 7
Unidirectional valve opening 6 is equipped with, the exhaust pilot hole 3 for extending downward into unidirectional 6 position of valve opening, institute are provided with the side wall of the upper cover 2
Be axially installed with spring 5 in the unidirectional valve opening 6 stated, the upper end of the spring 5 be connected with the lower end for being vented pilot hole 3 is blocked it is close
Blocking 4.
The exhaust pilot hole 3 is inclined to be arranged in the side wall of upper cover 2, and the upper end of the exhaust pilot hole 3 extends to
The madial wall top of upper cover 2, connection and reasonable arrangement, can improve the efficiency being vented.
The spring 5 is big top and small bottom turriform spring, and the deformation of turriform spring is more stable, ensures ball sealer
4 by can smooth return after open-top.
The ball sealer 4 is steel ball, improves service life.
The lower end of the exhaust pilot hole 3 is disposed with the cone shaped opening to match with ball sealer 4, can guarantee that ball sealer 4
The lower end for being vented pilot hole 3 is blocked.
As a kind of embodiment of the utility model, spring 5 is installed on motor flange 1, ball sealer 4 and 5 upper end of spring
Coordinate, upper cover 2 is adjacent to 1 upper surface of motor flange and is connected, while compresses ball sealer 4 and spring 5, and spring 5 has certain precompressed
Power.When the pump housing is vented, gases at high pressure down promote ball sealer 4 along exhaust pilot hole 3, while compress spring 5, arrange gas
Go out.
When the pump housing stops exhaust, 5 automatic homing of spring, ball sealer 4 withstands exhaust pilot hole 3 and seals, and prevents pump body
The negative pressure of generation sucks wet air or water, realizes the process of one-way exhaust.
The utility model is simple in structure, by setting exhaust pilot hole and the steel ball unidirectionally opened to realize one-way exhaust,
Solves the problem of pump housing stopping moment, the negative pressure that pump body produces sucks wet air or water.
