The air conditioning for automobiles guiding device
Technical field
The utility model relate to a kind of air conditioning for automobiles guiding device improvement, belong to the automobile air conditioning technology field.
Background technology
Guiding device links to each other with the air conditioning for automobiles main frame, can play the guiding air, reducing the air resistance of automobile when high-speed cruising also can make the moulding of air conditioning for automobiles more attractive in appearance simultaneously, as shown in Figure 1,1 is guiding device before the air conditioning for automobiles among the figure, 2 is the empty main frame of automobile, and 3 is guiding device behind the air conditioning for automobiles.The mounting structure of existing air conditioning for automobiles guiding device all adopts the outer face at air conditioning for automobiles host shell 5 to stretch out mounting bracket 4 as shown in Figure 2, and guiding device 7 is fixed on by bolt 6 and reaches the purpose that is connected with the air conditioning for automobiles main frame on the support 4.But this installation has obvious defects just to be: there is the slit guiding device below with roof, when automobile is in the high-speed cruising state, high velocity air from then on slit enters the guiding device inner chamber, the compressing guiding device is that fulcrum is acutely beated with the support, acutely beating of guiding device, except producing the high-decibel noise, influence the passenger and ride so also can pull support for a long time or tear the air conditioning for automobiles host shell outside the environment with car roof collision.
Summary of the invention
The purpose of this utility model is in order to overcome the disadvantage on the existing air conditioning for automobiles guiding device mounting structure, provide a kind of and have and to be installed to easily on the air conditioning for automobiles main frame, and can eliminate impact noise and pull support or tear the air conditioning for automobiles guiding device of the mounting structure of air conditioning for automobiles host shell danger.
The technical solution of the utility model is: guiding device is directly to be connected with air conditioning for automobiles host shell end plate by bolt, and also riveting on the guiding device has an adjustable support.
This mounting structure is to change by guiding device and the bolt bucketing of air conditioner for automobile host shell end plate originally installing by support, has solved the cantilever design when utilizing support to install, and installation strength is good.In addition, this structure has also been riveted an adjustable support, can reduce the slit of guiding device and roof, makes the air-flow that enters diversion cavity few, and the amplitude of beating is little, the danger of having eliminated impact noise like this and having pulled support or tear the air conditioning for automobiles host shell.

The specific embodiment
Fig. 3 is the utility model guiding device front view, Fig. 4 is the utility model guiding device birds-eye view, Fig. 5 is the A-A view of Fig. 3, by shown in Figure 5, the characteristics of the mounting structure of air conditioning for automobiles guiding device are, guiding device 7 directly is connected with air conditioning for automobiles host shell end plate 9 by bolt 10, promptly be to change guiding device originally to change the connection mode of using the bolt bucketing by guiding device and air conditioning for automobiles host shell end plate by the support installation, solved the cantilever design when utilizing support to install, installation strength is good.In addition, by shown in Figure 5, also riveted joint has an adjustable support 8 on guiding device 7, and moving up and down of adjustable support 8 drives guiding device 7 and move, by shown in Figure 6, adjustable support 8 is riveted on by rivet 12 on the glass-felt plastic of guiding device 7, and such structure can reduce the slit of guiding device and roof, makes the air-flow that enters diversion cavity few, the amplitude of beating is little, the danger of having eliminated impact noise like this and having pulled support or tear the air conditioning for automobiles host shell.
By Fig. 5, shown in Figure 7, be equipped with a big pad 11 between bolt 10 and its bonded assembly air conditioning for automobiles host shell end plate 9, the guiding device 7, be equipped with a seal ring 13 between big pad 11 and the air conditioning for automobiles host shell end plate 9.The area of contact of this big pad and air conditioning for automobiles host shell is big, and housing stressed more even is difficult for by drawing crack.In addition, design has ring structure on big pad, can prevent that exterior rainwater from entering coach air conditioner main frame inside along bolt hole, influences the refrigeration performance of air-conditioning.
