Embodiment
For making the object of the embodiment of the present invention, technological scheme and advantage clearly, below in conjunction with accompanying drawing, specific embodiment is described in detail.
Fig. 1 is the annexation schematic diagram of air-strainer and engine air inlet tube and connecting tube of the present invention, as shown in Figure 1, connecting tube 100 of the present invention can removably connect between air-strainer 200 and engine air inlet tube 300, described connecting tube 100 one end is connected with air-strainer 200, the other end is connected with engine air inlet tube 300, air along direction shown in arrow A in Fig. 1 from air-cleaner snorkel 500, air-strainer 200, connecting tube 100, engine air inlet tube 300, then enter into engine interior by closure (not shown).
Fig. 2 is the schematic diagram of connecting tube of the present invention, as shown in Figure 2, connecting tube 100 comprises tube wall 101, air output terminal 102 and air input 103, described air output terminal 102 is for being connected with described engine air inlet tube 300, and described air input 103 is for being connected with described air-strainer 200.Described tube wall 101 is provided with opening 104, described opening 104 be furnished with mutually can with the vent cover of its air-tight fit, described vent cover is removably mounted to described opening 104; Described vent cover according to the need of measure flow through described connecting tube 100 air mass flow and can optionally with flow transducer 10, such the present invention is by the combination of prior art air flow quantity sensor 105 with air-strainer 200 housing, become the joint of air flow sensor 105 and connecting tube 100, thus air-strainer 200 can be made to become versatility parts, housing need not be replaced and be namely applicable to new car type and traditional vehicle.
According to the design of the invention described above, described vent cover can be following two kinds of forms:
The first form: described vent cover is selected from the first vent cover 106 with flow transducer 105 as shown in Figure 3, the second vent cover 107 without described flow transducer 105 as shown in Figure 4, described first vent cover 106 and the second vent cover 107 all can with described opening 104 air-tight fit; As shown in Figure 3, described first vent cover 106 is fixedly connected with flow transducer 105; Wherein, when needing measurement to flow through the air mass flow of described connecting tube 100, described first vent cover 106 is mounted to described opening 104; When not needing to measure the air mass flow flowing through described connecting tube 100, described second vent cover 107 is mounted to described opening 104.That is, when needing measurement to flow through the air mass flow of described connecting tube 100, during as being applied to novel vehicle, the first vent cover 106 as shown in Figure 3 and described opening 104 air-tight fit; When not needing to measure the air mass flow flowing through described connecting tube 100, during as being applied to traditional vehicle, the second vent cover 107 as shown in Figure 4 and described opening 104 air-tight fit.Such air-strainer 200 and tube wall 101 become versatility parts, the vent cover (first vent cover 106 and the second vent cover 107) only needing production two kinds dissimilar, can according to the assembling using the difference (novel vehicle and traditional vehicle) of vehicle carry out suction tude 100, and then complete the configuration of gas handling system of different automobile types.As shown in Figure 3, the upper-end surface of described first vent cover 106 is provided with wire harness slot 113, flow transducer 105 by the flux signal that detects by the cable transmission in wire harness slot 113 to ECU.
The second form: described vent cover is the 3rd vent cover 108 being provided with draw-in groove 109 as shown in Figure 5, and described flow transducer 105 removably can be mounted to described draw-in groove 109; Only when needing measurement to flow through the air mass flow of described connecting tube 100, described flow transducer 105 is mounted to described draw-in groove 109.That is, flow through the air mass flow of described connecting tube 100 according to the need of measuring, described 3rd vent cover 108 to connect with described flow transducer 105 by described draw-in groove 109 and is separated.When needing measurement to flow through the air mass flow of described connecting tube 100, during as being applied to novel vehicle, described draw-in groove 109 is inserted in described flow transducer 105 one end, complete and fix with the 3rd vent cover 108, inserted by the other end of described flow transducer 105 in connecting tube 100, then the 3rd vent cover 108 carries out air-tight fit to complete the assembling of connecting tube 100 with connecting tube 100, when not needing to measure the air mass flow flowing through described connecting tube 100, during as being applied to traditional vehicle, described flow transducer 105 is extracted from described draw-in groove 109, complete and be separated with the 3rd vent cover 108, then described 3rd vent cover 108 is carried out air-tight fit to complete the assembling of connecting tube 100 with connecting tube 100, the manner is on the basis of above-mentioned first kind of way, further the 3rd vent cover 108 is become versatility parts, only need the vent cover (the 3rd vent cover 108) of production one type, coordinate the flow transducer 105 that market is general, can according to the assembling using the difference (novel vehicle and traditional vehicle) of vehicle to carry out suction tude 100, and then complete the configuration of gas handling system of different automobile types.
As shown in Figure 5, described draw-in groove 109 is arranged at the lower end surface (in figure dotted portion) of the 3rd vent cover 108, the upper-end surface of described 3rd vent cover 108 is provided with wire harness slot 113 (in figure bold portion), flow transducer 105 by the flux signal that detects by the cable transmission in wire harness slot 113 to ECU.
Fig. 6 is the schematic diagram of seal ring of the present invention, and as shown in Figure 6, described seal ring 400 is circular, and material is the elastic materials such as rubber, and described seal ring 400, between vent cover and opening 104, increases the tightness between described vent cover and opening 104.
Connect as a whole by screw and threaded fastener between vent cover of the present invention and opening, Fig. 7 is the Placement schematic diagram of vent cover of the present invention and opening, for the 3rd vent cover 108:
3rd vent cover 108 has two the first screws 110, and connecting tube 100 has two the second screws 111 matched with described first screw 110; Described vent cover is connected as a whole with described connecting tube 110 by described first screw 110 with the second screw 11 by threaded fastener 112.In other embodiments, other conventional Placement can be used to be connected with vent cover by opening.
When measurement flows through the air mass flow of described connecting tube 100, it is inner that described flow transducer 105 all should stretch into described connecting tube 100, to make measurement accurate.
As a kind of preferred version, seal ring can be equipped with between described connecting tube 100 and air-strainer 200, engine air inlet tube 300, described seal ring can replace with above-mentioned seal ring 400, described seal ring is for increasing the tightness between described connecting tube 100 and described air-strainer 200, and the tightness between described connecting tube 100 and engine air inlet tube 300.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
