Abstract
The invention discloses a drain pipe structure for an automobile air conditioner. The drain pipe structure for the automobile air conditioner comprises a drain pipe (1), a sheet metal hole (31) and a pier head (2), wherein the sheet metal hole (31) is formed in a sheet metal (3); the pier head (2) is arranged at the end part of the drain pipe (1); the diameter of the pier head (2) is larger than that of the drain pipe (1); a mounting hole in which the drain pipe (1) is mounted is formed in the pier head (2); and the pier head (2) is adaptive to the sheet metal hole (31). A bending part extending inwards is arranged around the sheet metal hole (31); and through the bending part, the sheet metal hole (31) is formed with a depth. As the matching length of the drain pipe (1) in the sheet metal (3) is increased, the NVH (Noise Vibration and Harshness) sealing effect is especially good. And moreover, after a matching structure is lengthened, the corresponding stability and structural performance are also stable.
Description
Technical field
The invention belongs to automobile air conditioning technology field, particularly relate to a kind of drainage pipe structure for automobile air conditioner.
Background technology
Along with the fast development of auto trade, client requires more and more higher to the comfort level of automobile, and new science and technology up-to-date technology is also continuous derivative, and therefore the special structure for auto NVH is also constantly brought forth new ideas development.
Realizing in process of the present invention, contriver finds that prior art at least exists following problem: traditional docking structure drain hose is directly linked on panel beating, and sealing effectiveness is poor.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of good sealing effect, assembles drainage pipe structure for automobile air conditioner that is simple, difficult drop-off.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of drainage pipe structure for automobile air conditioner, has:
Drain hose;
Be arranged on the stamping holes on panel beating;
Be arranged on the pier nose of drain hose end, the diameter of described pier nose is greater than the diameter of drain hose, and pier nose is provided with the mounting hole fixed a drainpipe; Described pier nose and stamping holes suitable.
Described stamping holes surrounding is provided with the kink extended internally, and described kink makes stamping holes form a degree of depth.
The length of described pier nose is greater than the degree of depth of stamping holes.
Described pier nose is provided with the outer rim of outward extending covering stamping holes.
Described pier nose periphery is set with seal ring, and described pier nose and stamping holes are sealed and matched.
Described pier nose is provided with the buckle bottom clamping stamping holes.
Described pier nose and drain hose are quality of rubber materials.
A technical scheme tool in technique scheme has the following advantages or beneficial effect, and by arranging the pier nose of increasing, drain hose has very large length of fit in panel beating, therefore NVH sealing effectiveness is also good especially.Moreover after fit structure lengthening, corresponding stability, structural behaviour is also more stable.
Accompanying drawing explanation
The structural representation of drainage pipe structure for automobile air conditioner of Fig. 1 for providing in the embodiment of the present invention;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the cutaway view of Fig. 2;
Mark in above-mentioned figure is: 1, drain hose, and 2, pier nose, 21, outer rim, 22, seal ring, 3, panel beating, 31, stamping holes.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
See Fig. 1, a kind of drainage pipe structure for automobile air conditioner, has:
Drain hose 1;
Be arranged on the stamping holes 31 on panel beating 3;
Be arranged on the pier nose 2 of drain hose 1 end, the diameter of pier nose 2 is greater than the diameter of drain hose 1, pier nose 2 be provided with fix a drainpipe 1 mounting hole; Pier nose 2 is suitable with stamping holes 31.
Stamping holes 31 surrounding is provided with the kink extended internally, and kink makes stamping holes 31 form a degree of depth.Increase the length of fit of drain hose 1 in panel beating 3, therefore NVH sealing effectiveness is also good especially.Moreover after fit structure lengthening, corresponding stability, structural behaviour is also more stable.
The length of pier nose 2 is greater than the degree of depth of stamping holes 31.
Pier nose 2 is provided with the outer rim 21 of outward extending covering stamping holes 31.Heavy caliber pier nose 2 large about 1.5mm more monolateral than stamping holes 31 edge, leak tightness when so not only meeting assembling also meets the effect that can not rock.
Pier nose 2 periphery is set with seal ring 22, and pier nose 2 and stamping holes 31 are sealed and matched.Realize sealing.
Pier nose 2 is provided with the buckle bottom clamping stamping holes 31.Pier nose 2 is made to be connected more solid and reliable with panel beating 3.
Pier nose 2 and drain hose 1 are quality of rubber materials.1. structure is simply firm, the resilient characteristic of recycling rubber, makes rubber drain 1 better with the sealing effectiveness of vehicle body sheet metal 3, thus reaches the requirement of NVH; 2. easy to operate, directly insert after docking with car load; 3. cost is low, and do not need with band and caulking gum, also do not need to do frock, fitting operation is easy; 4. draining is smooth, and therefore interface water outlet place adopts heavy caliber water outlet, therefore drain hose 1 there will not be problems such as blocking.
Adopt plug-in type fit structure layer by layer, not only achieve car load NVH sealing effectiveness, also simplify assembly technology and achieve the effect of easy accessibility, the problem of drain hose 1NVH poor sealing that actv. solves.
A technical scheme tool in technique scheme has the following advantages or beneficial effect, and by arranging the pier nose 2 of increasing, drain hose 1 has very large length of fit in panel beating 3, therefore NVH sealing effectiveness is also good especially.Moreover after fit structure lengthening, corresponding stability, structural behaviour is also more stable.Fixing firm, NVH is effective, can repeatedly dismantle.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
