Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to fig. 1, the utility model provides a high strength vehicle vent-pipe, include:

the exhaust pipe body 1 is of a bent tubular structure with openings at two ends, one end is a connecting end, and the other end is an exhaust end;

the inner wall of the exhaust pipe body 1 is coated with the heat insulation layer 2;

the inner walls of the two end ports of the exhaust pipe body 1 are fixedly connected with the supporting circular rings 3 in a fitting manner;

the inner bending support ring 4 is fixedly attached to the inner wall of the bending part of the exhaust pipe body 1;

the outer bending support plate 5 is attached and fixedly connected to the outer wall of the bent part of the exhaust pipe body 1.

As an embodiment of the utility model, support the outer lane wall of ring 3 with the fixed laminating of insulating layer 2, support and set up chevron shape support column 31 on the ring 3, the trilateral of chevron shape support column 31 with the fixed laminating of inner lane wall of supporting ring 3.

As an embodiment of the present invention, a triangular wind guiding groove 32 is further disposed on the herringbone supporting column 31.

As an embodiment of the present invention, the inner bending support ring 4 is a waist-shaped structure, the outer wall of which is fixedly attached to the thermal insulation layer 2, and the inner wall of the inner bending support ring 4 is fixedly attached to the X-shaped support column 41.

As an embodiment of the present invention, the outer bending support plate 5 is a plate-shaped structure, and the inner end surface of the outer bending support plate 5 and the exhaust pipe body 1 are provided with a reinforcing stud 51 therebetween.

The working principle of the technical scheme is as follows: as a tubular structure body, the automobile tail gas pipe has poor impact resistance in the using process, so that the self strength of the tail gas pipe needs to be improved on the basis of the original structure. For this purpose, the following measures are taken, firstly, two supporting circular rings 3 are fixedly bonded or welded in the exhaust pipe body 1 near the two end ports for improving the shock resistance of the pipe body. In order to improve the supporting capability of the supporting ring 3 and facilitate the emission of tail gas, the herringbone supporting columns 31 are arranged in the supporting ring 3, and the triangular air guide grooves 32 are further arranged on the herringbone supporting columns 31, so that the integral supporting strength of the supporting ring 3 can be improved, and the triangular air guide grooves 32 have a guiding effect on the air flow of the tail gas.

The inner bending support ring 4 and the outer bending support plate 5 are used for facilitating the fixing effect of the exhaust pipe body 1 at the bending part and preventing the bending angle of the bending part from changing due to external force.

The beneficial effects of the above technical scheme are that: the utility model provides a high strength vehicle vent-pipe, the tracheal radial shock resistance of improvement automobile tail and the crooked solid intensity of forming of improvement automobile tail that can to a great extent can effectively improve the tracheal intensity of tail, prolongs its life.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit of the present invention.
