Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] see figure 1 , an automobile air-conditioning drainage pipe structure, has:

[0022] Drainpipe 1;

[0023] The sheet metal hole 31 provided on the sheet metal 3;

[0024] The pier head 2 arranged at the end of the drain pipe 1 has a diameter greater than that of the drain pipe 1, and the pier head 2 is provided with a mounting hole for installing the drain pipe 1; the pier head 2 is matched with the sheet metal hole 31.

[0025] The sheet metal hole 31 is surrounded by a bending portion extending inward, and the bending portion makes the sheet metal hole 31 form a certain depth. The matching length of the drain pipe 1 in the sheet metal 3 is increased, so the NVH sealing effect is particularly good. Furthermore, after the ma...

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 [0001] The invention belongs to the technical field of automobile air conditioners, in particular to an automobile air conditioner drainage pipe structure. Background technique [0002] With the rapid development of the automobile industry, customers have higher and higher requirements for the comfort of automobiles, and new technologies and new technologies are constantly being derived. Therefore, the structure dedicated to automobile NVH is also constantly innovating and developing. [0003] In the process of realizing the present invention, the inventors have found that the prior art has at least the following problems: the drainpipe of the traditional butt joint structure is directly connected to the sheet metal, and the sealing effect is poor. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an automobile air-conditioning drain pipe structure with good sealing effect, simple assembly and not e...
