Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in fig. 1 to 3, a foot blowing damper mounting structure of an automotive air conditioner relates to parts of an air conditioning system, and includes an HVAC case 1 and a foot blowing damper 2, a foot blowing air outlet 1a is provided on a side wall a of an air outlet section of the HVAC case 1, the foot blowing damper 2 includes a rotating shaft 2a and a wind shield 2b integrally formed on the rotating shaft 2a, the rotating shaft 2a is rotatably mounted in the HVAC case 1, the wind shield 2b extends outward along a radial direction of the rotating shaft 2a, that is, a plane where the wind shield 2b is located is perpendicular to an axis of the rotating shaft 2a, the wind shield 2b is a sheet structure, the wind shield 2b is slightly larger than an aperture of the foot blowing air outlet 1a, and in a rotating process of the rotating shaft 2a, the wind shield 2b rotatably slides against the side wall a of the HVAC case 1, and the wind shield 2b rotatably slides to the foot blowing air outlet 1a, so that the foot blowing air outlet 1a can be closed.

Utilize deep bead 2b shutoff to blow sufficient air outlet 1a to open and close in the mode of pasting lateral wall a rotary-cut, blow sufficient air door 2 and only can occupy the little space of air-out section, thereby guarantee that HVAC assembly air-out section can mix more amount of wind, and then reduce the velocity of flow that the air current blew out, avoid forming the air current noise.

As shown in fig. 2, a reinforcing rib 2c is provided between the wind shield 2b and the rotation shaft 2a, and the reinforcing rib 2c can enhance the structural strength of the blow door 2.

As shown in fig. 1 again, in the present embodiment, the foot-blowing outlet 1a is opened at a position close to the top wall b of the HVAC housing 1, that is: the foot-blowing outlet 1a is partially formed by a top wall b, and the other part of the edge is formed on a side wall a. The side wall a is provided with a raised flange c corresponding to the edge of the foot blowing air outlet 1 a. It can be seen from fig. 4 and 5 that be equipped with first adhesive tape 3 on the edge of deep bead 2b one end, be equipped with second adhesive tape 4 on the edge of the other end, first adhesive tape 3 extends along the planar horizontal direction in deep bead 2b place, second adhesive tape 4 is for the vertical downwardly extending in deep bead 2b place plane, in the air door 2 that blows to the foot closed in-process, first adhesive tape 3 warp along the horizontal direction, and the elasticity butt is on roof b, second adhesive tape 4 also warp along the horizontal direction, and the elasticity butt is at the side of flange c.
