Embodiment 1
Referring to Fig. 1, the present embodiment provides a kind of tailpipe structure 100, including sequentially connected first tube body 110,
Second tube body 120 and flow distribution plate 130.
One end of first tube body 110 is equipped with interface 111, and the other end is connected to the second tube body 120.Second tube body 120 is equipped with
Opened type semi-circular structure, so that the gas of the first tube body 110 discharge is shunted from open-mouth.Flow distribution plate 130 is inclined at second
120 tail end of tube body, so that the gas path run-off the straight being discharged from the second tube body 120.
Fig. 2 and Fig. 3 are please referred to, further, in the preferred embodiment, the first tube body 110 is hollow circular tube structure,
Including bend loss 112 and straight pipe 113, the end of bend loss 112 is arranged in interface 111, and the both ends of straight pipe 113 are respectively communicated with
Bend loss 112 and the second tube body 120.Interface 111 with the silencer (not shown) of exhaust system for connecting.Tail gas is from interface
After 111 enter, by entering straight pipe 113 after bend loss 112, flow-through gas is formed.
Further, in the preferred embodiment, the second tube body 120 and 110 connecting pin of the first tube body are equipped with flaring structure
121.Flaring structure 121 is to be set to 110 edge of the first tube body week and be inclined outwardly.Flaring structure 121 makes the second tube body 120
Diameter h2 is greater than the diameter h1 of the first tube body 110, and tail gas enters bigbore second tube body from small-bore first tube body 110
120, it quickly spreads, and exhaust resistance reduces.Preferably, h2 ratio h1 increases 4%-5%.Under the ratio, resistance reducing effect is good, and keeps away
Exempt from the volume for excessively increasing tail pipe.
Further, in the preferred embodiment, axial direction of second tube body 120 along 110 straight sections 113 of the first tube body
Extend, and the tail portion of the second tube body 120 gradually raises to form spoon-shaped portion 122.Spoon-shaped portion 122 forms similar semicircle to direct current tail gas
The semi-surrounding structure of shape forms splendid exhaust effect.Spoon-shaped portion 122 has the open face 123 of one with axis direction level, opens
The height h3 in mouth face 123 is about 0.4-0.6 times of the second pipe diameter h2, is 0.47 times further.By the way that spoon-shaped portion is arranged
122 height improves the shunting effect of direct current tail gas, under the height, can be effectively disperseed to tail gas, so that temperature is effective
It reduces, and semicircular structure is excellent to the reduction function and effect of exhaust resistance.
Further, in the preferred embodiment, the angle [alpha] of the cross section of flow distribution plate 130 and the second tube body 120 be 30 °-
60°.It is further preferable that α is 40 ° -50 °, further, α is 45 °.Outlet gas flow path of the inclination of flow distribution plate 130 gear in straight tube tail gas
On, straight tube tail gas is blown on flow distribution plate 130, is carried out point dispersion discharge and a heat dissipation to tail gas, is avoided local temperature excessively high.When α is
At 45 °, it can guarantee that most of straight tube tail gas is contacted with flow distribution plate 130 and radiate, straight tube tail gas can be good under the gradient
Good diffusion.Further, flow distribution plate 130 is used to accept the 1.8- that the width h4 of the continuing surface of tail gas is the second pipe diameter h2
2.2 again.The medium position of flow distribution plate 130 is arranged in second tube body 130.By the way that wider flow distribution plate 130 is arranged, by straight tube tail gas
Disperse and radiate towards two sides in flow distribution plate 130, promotes shunting and heat dissipation effect.
Further, in the preferred embodiment, the opposite sides in 130 path of flow distribution plate is equipped with baffle 131.Preferably,
Baffle 131 is inclined outwardly, with flow distribution plate 130 substantially be in 60 °, flow distribution plate 130 two sides be arranged baffle 131, further to from
The tail gas that 130 two sides of flow distribution plate shunt radiates.
Referring to Fig. 4, further, in the preferred embodiment, flow distribution plate 130 and the second tube body 120 pass through link block
The outer end face of the second tube body 120 is arranged in 132 connections, one end of link block 132, and the other end is connected to flow distribution plate 130.Flow distribution plate
There is gap, (connection type can be welding to the two by the connection of link block 132 between 130 tail end and the second tube body 120
Deng), flow distribution plate 130 and the second tube body 120 do not occur directly to contact, and avoid contact with site in such a way that link block 132 contacts
Temperature is excessively high.
The present embodiment also provides a kind of automobile, including car body and above-mentioned tailpipe structure 100.It is understood that
It is that automobile can be the vehicles such as pony car, car, states tailpipe structure 100 in use, it can be effectively to tailpipe
Air-flow dispersed, greatly reduce the local temperature of tail pipe, substantially increase fire savety, and reduce tailpipe resistance
Power.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Within then, any modification, equivalent replacement, improvement and so on be should be included within the scope of protection of this utility model.
