Embodiment Construction

[0018] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and through the description of the preferred embodiments.

[0019] like figure 1 As shown, this kind of automobile air-conditioning HVAC wind deflector includes a damper shaft 3 installed on the vehicle air-conditioning HVAC and a damper plate 1 connected with the damper rotary shaft 3. The damper rotary shaft 3 is driven by the damper motor, and the damper plate 1 is provided with a windshield. Door panel wing 2. When the HVAC of the automobile air conditioner needs to switch the blowing mode, the damper motor drives the damper shaft 3 to rotate, and then drives the damper plate 1 to rotate accordingly; The wind pressure acting on the damper blade 2 causes the wind to generate lift on the damper panel 1 at the position of the damper blade 2; the lift on the damper panel 1 balances out part of the wind pressure on the damper panel 1, r...

Abstract

The invention discloses an automobile air conditioner HVAC air guide plate, which comprises an air valve rotating shaft arranged on an automobile air conditioner HVAC and a air valve plate connected with the air valve rotating shaft, wherein an air valve plate wing is arranged on the air valve plate; when the automobile air conditioner HVAC needs to be switched to the air blowing mode, an air valve motor drives the air valve rotating shaft to rotate, and further drives the air valve plate to rotate in a following way; air pressure is exerted onto the air valve plate and the air valve plate wing, under the guide effect of the air valve plate wing, t the air generates ascending force on the air valve plate in the air valve plate wing position through the air pressure acting onto the air valve plate wing by the air; a part of air pressure on the air valve plate is balanced away through the ascending force of the air valve plate, so that the twisting moment of the air valve rotating shaft is reduced; the air valve plate is smoothly opened; the air guide plate is smoothly opened; the fast and successful conversion of the air blowing mode can be realized.

Description

technical field [0001] The present invention relates to the field of automobile air conditioners, and more particularly, the present invention relates to an automobile air conditioner HVAC wind deflector. Background technique [0002] At present, in most of the automotive air conditioning HVAC, the automotive air conditioning HVAC realizes the conversion of the blowing mode through the air deflector. The air deflector usually includes a damper plate and a damper shaft connected to the damper plate, and the damper shaft rotates under the drive of a rotary shaft motor. When switching the blowing mode, the damper shaft drives the damper plate to rotate, and the wind pressure generated by the blower acts on the damper plate to generate pressure, which makes it difficult for the damper plate to rotate and the HVAC air deflector to open. The car air conditioner HVAC requires the air deflector to be opened smoothly when the blowing mode is changed. SUMMARY OF THE INVENTION [0...
