Problems solved by technology

Because the damper is a necessary auxiliary part, it has both positive and negative effects. Through the structural design of the damper, the positive effect can be improved and the negative effect can be reduced. However, the existing technology has the disadvantages of slow heating rate and reduced comfort.

Embodiment 1

[0055] see figure 1 — Figure 8 , an eccentric damper system for an automobile air conditioner, comprising an air-conditioning box 2 and an air-conditioning damper 1 arranged inside thereof, wherein the air-conditioning box 2 is provided with a thermal upper limit platform 21, a thermal lower limit platform 22, a cold upper limit platform 23, The lower cold limiting platform 24, the hot upper limiting platform 21 and the lower thermal limiting platform 22 are clamped to form a hot air channel 25, and the cold upper limiting platform 23 and the lower limiting platform 24 are clamped to form a cold air channel 26; The inner ends of the thermal upper limit platform 21, the lower thermal limit platform 22, the cold upper limit platform 23, and the cold lower limit platform 24 are all connected with the bottom shell 20 in the air-conditioning casing 2, and the outer ends all extend outward; The damper 1 is a curved structure, including a hot air plate 3 and a cold air plate 4. The...

Embodiment 2

[0057] Basic content is the same as embodiment 1, the difference is:

[0058] The part on the bottom shell 20 connected with the thermal upper positioning platform 21 is the thermal upper plate 201, and the vertical distance between the thermal upper plate 201 and the axis center of the inner rotating shaft 70 is the basic air duct width 501, and the inner rotating shaft The vertical distance between the axis of 70 and the plate-plate connecting portion 5 is the expanded air duct width 502 , which is 15%-40% of the basic air duct width 501 . Preferably, the expanded air duct width 502 is 20% of the basic air duct width 501 .

Embodiment 3

[0060] Basic content is the same as embodiment 1, the difference is:

[0061] The inner wing plate 60 and the outer wing plate 6 are triangular structures, including the hot side bevel 61, the cold side bevel 62 and the bottom fold 63 connected in sequence; the hot air plate 3 is located at the hot free end 31 1. The plate surface between the hot rotating ends 32 is aligned with the bottom end of the hot-side bevel 61, and the top of the hot-side bevel 61 and the top of the cold-side bevel 62 are jointly clamped and connected with the inner rotating shaft 70 or the outer rotating shaft 7. The side wall, the plate surface between the cold free end 41 and the cold rotating end 42 on the cold air plate 4 is aligned and connected with the bottom end of the cold side hypotenuse 62 . The bottom flange 63 includes a hot bottom hypotenuse 631 and a cold bottom hypotenuse 632, and the board surface near the hot air plate 3 on the panel connection part 5 is connected to the hot bottom h...

Abstract

The invention discloses an eccentric air door system of an automobile air conditioner, comprising an air conditioner box body and an air conditioner air door arranged in the air conditioner box body,wherein a heat upper limiting table, a heat lower limiting table, a cold upper limiting table and a cold lower limiting table are arranged in the air conditioner box body, and the air conditioner airdoor is of a curved structure and comprises a hot air plate and a cold air plate; the hot free end of the hot air plate moves steplessly between the heat upper limiting table and the cold upper limiting table; the cold free end of the cold air plate moves steplessly between the heat upper limiting table and the cold upper limiting table, and the hot rotating end of the hot air plate is connected to the cold rotating end of the cold air plate to form a plate-plate connecting part; the two ends of the plate-plate connecting part are connected to the bottom of the inner wing plate and the bottomof the outer wing plate respectively, the top of the inner wing plate and the top of the outer wing plate are hinged to one end of an inner rotating shaft and one end of an outer rotating shaft respectively, the other end of the inner rotating shaft is connected to a bottom shell, and the inner wing plate, the outer wing plate and the plate-plate connecting part form a concave expanding air duct.Through the design, the passing area of a hot air channel can be increased, and a temperature rising speed is high.

Description

technical field [0001] The invention relates to a damper for a vehicle, which belongs to the technical field of automobiles, in particular to an eccentric damper system for an automobile air conditioner. Background technique [0002] With the improvement of people's living standards, users have higher and higher requirements for the comfort of commercial vehicles. Vehicle air conditioners are one of the most direct indicators of comfort evaluation, and the cooling rate and heating rate are the key manifestations of the performance of the air conditioning system. [0003] The damper in the automotive air-conditioning system is mainly used to guide the flow of wind. The user operates the air-conditioning control mechanism, and the control mechanism outputs instructions to the damper. The damper changes its state according to the instruction to meet the user's needs. Because the damper is a necessary auxiliary part, it has both positive and negative effects. Through the struct...
