Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of accompanying drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings blast pipe 100 according to embodiments of the present invention is described in detail, the blast pipe 100 can be applied
In the gas extraction system of vehicle.
As shown in figure 1, gas extraction system can include muffler and blast pipe 100, the waste gas handled by muffler noise reduction
It can be discharged into by blast pipe 100 in external environment.
Blast pipe 100 according to embodiments of the present invention can include：Body 10, sealing valve 20 and support member 23, body 10
On be provided with osculum 11, osculum 11 can be used for excluding the water in body 10, so as to avoid water from freezing in body 10
Knot.Preferably, osculum 11 can be located at the minimum point of body 10.Water so in body 10 is easy to converge at minimum point,
So as to be easy to osculum 11 outwards to discharge.
Sealing valve 20 is arranged on body 10, and sealing valve 20 can be used for sealing osculum 11.Thus, at vehicle
When the process of traveling, sealing valve 20 can seal osculum 11, so can be with so that the normal exhaust of blast pipe 100
Avoid producing exhaust noise, it is ensured that the NVH performances of vehicle.
Support member 23 optionally supports body 10 so that sealing valve 20 and body 10 separate, so as to which depressurization valve 20 is right
The sealing of osculum 11.
It is understood that during normal vehicle operation, sealing valve 20 can seal osculum 11, terminate in vehicle
After travelling a period of time, support member 23 can support sealing valve 20 from body 10, so can be right with depressurization valve 20
The sealing state of osculum 11, so that osculum 11 can discharge the water of convergence, and then blast pipe 100 can be avoided to accumulate
Water, and blast pipe 100 can be avoided to occur situation about freezing in the winter time.
Thus, blast pipe 100 according to embodiments of the present invention, it is ensured that the normal exhaust of itself, can avoid producing
Exhaust noise, it is ensured that the NVH performances of vehicle, and ponding can also be discharged after vehicle terminates traveling, can the row of avoiding
There is situation about freezing in the winter time in tracheae 100, it is ensured that the normal use of vehicle.
According to the specific embodiment of the present invention, as shown in Figures 2 and 3, sealing valve 20 can include：Valve seat 21 and valve
Body 22, valve seat 21 can be movably attached on body 10, can so be advantageous to support member 23 by valve seat 21 from body 10
Support, valve body 22 is arranged on valve seat 21, and valve body 22 is used to seal osculum 11, when support member 23 by valve seat 21 from pipe
After being supported on body 10, valve body 22 releases the sealing to osculum 11.
Alternatively, as shown in Figures 2 and 3, the middle part of valve body 22 is recessed, and the both sides of valve body 22 are curved, arc
Curvature is identical with the curvature of blast pipe 100.Coordinate reliability preferable so between valve body 22 and body 10, so that valve
The effect that body 22 seals osculum 11 is preferable, can avoid producing exhaust noise, can better ensure that the NVH performances of vehicle.
Further, as shown in Figures 2 and 3, support member 23 can include：Actuator 231, support bar 232 and supporter
233, actuator 231 is arranged on valve seat 21, and actuator 231 drives length direction of the support bar 232 along support bar 232 to move.
Wherein, the length direction of support bar 232 is above-below direction, and actuator 231 can drive support bar 232 to move along the vertical direction.
Specifically, actuator 231 can be motor, gear is provided with motor, the infrastructure of support bar 232 is tooth
Bar, gear and rack engagement.So, the drive efficiency of motor is high, and the translational speed of support bar 232 is fast, can cause valve body
22 switch rapidly between sealing osculum 11 and the state of depressurization osculum 11.And by between gear and rack
Coordinate, it is ensured that the reliable transmission between motor and support bar 232.Motor can rotate and reverse.
Supporter 233 is arranged on support bar 232 towards the end of body 10, and supporter 233 is suitable to support body 10.Can be with
Understand, when motor driving support bar 232 moves up, supporter 233 moves up with support bar 232, directly
Support and be supported on body 10 to end, then supporter 233 continues to support body 10, until valve body 22 and body 10 separate, from
And valve body 22 releases the sealing to osculum 11, osculum 11 carries out drain operation.
Wherein, motor from valve body 22 and body 10 is run to by the moving displacement of this section of support bar 232 to be separated
For idle stroke, motor will be separated to this section of support bar that valve body 22 is completely separated with body 10 from valve body 22 and body 10
232 moving displacements are effective travel.
A kind of data instance of idle stroke and effective travel is provided below, design idle stroke can be 5mm, and effective travel can
Think 5mm.So, the rack of the bottom of support bar 232 is at least 10mm.
Alternatively, as shown in Figures 2 and 3, sleeve 221 can be provided with valve body 22, support bar 232 passes through sleeve 221.
Thus, support bar 232 can pass through valve body 22, and sleeve 221 can play guiding and position-limiting action at least to some extent, so as to
Support bar 232 can be caused to move along the vertical direction, and then the functional reliability of sealing valve 20 can be improved.
Preferably, the middle part of supporter 233 is recessed, and the both sides of supporter 233 are curved, the curvature and body of arc
10 curvature is identical.So when supporter 233 supports body 10, cooperation reliability between supporter 233 and body 10 compared with
It is good, so as to be easy to osculum 11 to carry out drain operation.
Wherein, as shown in Fig. 2 sealing valve 20 can also include：Holddown spring 24, holddown spring 24 are connected to the He of valve seat 21
Between body 10.Valve body 22 effectively can be pressed on body 10 by holddown spring 24, can so ensure the sealing row of valve body 22
The validity in water hole 11, it can avoid producing exhaust noise, the NVH performances of vehicle can be better ensured that.
Vehicle according to embodiments of the present invention, include the blast pipe 100 of above-described embodiment.
