Description
Technical field
The utility model relates to cold air air inlet pipe admission port hermetically-sealed construction technical field.
Background technology
Automotive air intake pipe is the most upstream of automotive engine air intake system, and this air inlet parts is fastened in the supporting construction on radiator top usually, and is placed in the below of engine compartment cover.For conserve space, the induction part of automotive air intake pipe is generally flats.Therefore, series of problems is which created:
When automotive operation, due to the reason such as blast, vibration, cause inevitably mutually colliding with between air inlet parts and engine compartment cover, especially when receiving severe jolt, strongly, although air inlet pipe adopts the nonrigid materials such as plastics, if things go on like this air inlet pipe can be extruded distortion in collision between air inlet parts and engine compartment cover, cause deficiency of air, even can cause during serious vibration air inlet pipe or supporting construction impaired.
Air inlet pipe admission port and machinery space do not completely cut off, and in machinery space, hot air level of oxygen is low, and after hot air enters driving engine by air inlet pipe, engine combustion is insufficient, and engine power reduces.
Utility model content
The purpose of this utility model is for the structural shortcoming of prior art, proposes a kind of cold air air inlet pipe admission port hermetically-sealed construction, is achieved through the following technical solutions:
A kind of cold air air inlet pipe admission port hermetically-sealed construction, for being arranged in automobile engine nacelle, described cold air air inlet pipe is the hollow tubular structure with admission port and air extractor duct, it is characterized in that: described cold air air inlet pipe is made up of sealing band, entrance termination, upper tube body and lower tube body; Described upper tube body and lower tube body are buckled into a hollow tube up and down, and described entrance termination is dustpan shape, have diapire and are erected in the left and right sidewall of diapire both sides, and the upper end of this left and right sidewall is domatic and the top of this domatic is connected by a roof and is integrated; The rear end of described entrance termination forms an interface that enclosed by diapire, left and right sidewall and roof and described hollow tube end is suitable; Described left and right sidewall end face and roof front end all have flange, and the flange of three forms a continuous print curved surface, described sealing band is arranged on described flange, when described cold air air inlet pipe is installed in automobile engine nacelle, vehicle engine hatch cover is oppressed described sealing band and is formed described admission port in the front end of described entrance termination.
The medial surface shape adaptation of described curved surface and vehicle engine hatch cover.
Described upper tube body and the detachable fastening of lower tube body.
Described entrance termination is connected with described hollow tube end is detachable.
Described detachable connection is referred to and is connected by buckle.
Compared with prior art, the beneficial effects of the utility model are: by the inlet end of air inlet pipe being arranged to detachable dustpan shape structure, and flange is set in upper end with fixing rubber strip, when such vehicle engine hatch cover is closed, the inlet end that vehicle engine hatch cover can oppress sealing band and air inlet pipe encloses admission port jointly.Bring two benefits like this: when 1, there is relative displacement between admission port and engine compartment cover, rubber strip meeting compression set and then recovery, collision energy becomes the elastic deformation energy of rubber strip, makes air inlet pipe not fragile.Even if the scope that the collision between 2 admission ports and engine compartment cover can compensate beyond rubber strip, the admission port connected is damaged perhaps plastic deformation, also can repair by changing admission port, and need not change whole air inlet pipe, reduce cost of repair.
Accompanying drawing explanation
By the description carried out its exemplary embodiment below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the utility model will become apparent and easy understand.
Fig. 1 is the utility model embodiment air feeder structure schematic diagram I;
Fig. 2 is the utility model embodiment air feeder structure schematic diagram II.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, so that the understanding of technical personnel of the same trade:
Shown in Fig. 1-2, provide a kind of cold air air inlet pipe admission port hermetically-sealed construction in the present embodiment, this cold air air inlet pipe is used for being arranged in automobile engine nacelle.The same with prior art, cold air air inlet pipe is the hollow tubular structure with admission port and air extractor duct, and difference is: cold air air inlet pipe is made up of sealing band 1, entrance termination 2, upper tube body 3 and lower tube body 4.Wherein:
Upper tube body 3 and lower tube body about 4 are buckled into a hollow tube.Specifically, upper tube body 3 and lower tube body 4 are roughly enough in the form of slot, the two mutual split, and are connected by buckle structure, thus are combined into a body.
Entrance termination 2 entirety is in dustpan shape.Entrance termination 2 has diapire 21 and is erected in left side wall 22 and the right side wall 23 of diapire 1 both sides, and the end face of left side wall 22 and right side wall 23 is domatic and the two top is connected by a roof 24 and is integrated.Thus, the rear end of entrance termination 2 formed one by diapire 21, the interface suitable with hollow tube end that jointly encloses of top 24, left side wall 22 and right side wall 23.Detachable connection is realized by buckle between entrance termination 2 and hollow tube.
In addition, the end face of left side wall 22 and right side wall 23, and roof 24 front end all has flange 25, and the flange 25 of three forms a continuous print curved surface, the medial surface shape adaptation of this curved surface and vehicle engine hatch cover.Meanwhile, sealing band 1 is arranged on described flange 25, and when cold air air inlet pipe is installed in automobile engine nacelle, vehicle engine hatch cover is oppressed sealing band 1 after closing and formed admission port in the front end of entrance termination 2.
Compared with prior art, the beneficial effects of the utility model are: by the inlet end of air inlet pipe being arranged to detachable dustpan shape structure, and flange is set in upper end with fixing rubber strip, when such vehicle engine hatch cover is closed, the inlet end that vehicle engine hatch cover can oppress sealing band and air inlet pipe encloses admission port jointly.Bring three benefits like this: when 1, there is relative displacement between admission port and engine compartment cover, rubber strip meeting compression set and then recovery, collision energy becomes the elastic deformation energy of rubber strip, makes air inlet pipe not fragile.Even if the scope that the collision between 2 admission ports and engine compartment cover can compensate beyond rubber strip, the admission port connected is damaged perhaps plastic deformation, also can repair by changing admission port, and need not change whole air inlet pipe, reduce cost of repair.3, open isolated to air inlet pipe admission port and machinery space, avoid hot air in machinery space and flow into air inlet pipe, make engine combustion more abundant.
It should be noted that; above content is in conjunction with concrete embodiment further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; under the guidance of above-described embodiment; those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improve or distortion drops in protection domain of the present utility model.
