Embodiment Construction

[0021] The internal and external circulation bowl-shaped damper proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0022] The core idea of ​​the present invention is to provide an internal and external circulation bowl-shaped damper, which is arranged in the air intake box housing of the air-conditioning box in the automobile. The internal and external circulation bowl-shaped damper includes a windshield, two side plates and two rotating shafts , the two side plates are respectively arranged on both sides of the windshield, the two rotating shafts are respe...

Abstract

The invention provides a bowl-shaped internal and external circulation type air door, which is arranged in an air inlet box shell of an air conditioning cabinet in an automobile. The bowl-shaped internal and external circulation type air door comprises an air damper, two side plates and two rotating shafts, wherein the two side plates are arranged on the two sides of the air damper respectively; the two rotating shafts are arranged in the two side plates in a penetration way respectively, and can rotate to drive the two side plates and the air damper to rotate together; and a staggered grid is arranged on the side, which is away from the rotating shafts, of the air damper. According to the bowl-shaped internal and external circulation type air door, variable radius chamfers have stronger structural strength and higher stress relief resistant capability, can be used for better supporting the side plates of the air door, and are favorable for preventing the deformation of the air door, so that the risk that the air door is separated from the air inlet box shell is lowered; the design of the staggered grid can have a function of rectifying airflow at an inlet of the air conditioning cabinet, so that the problem that turbulence noise is easily produced when the air damper runs to a specific position is improved; and in addition, the staggered grid can also have a function of supporting and strengthening the air damper.

Description

technical field [0001] The invention relates to a component of an automobile air-conditioning box, in particular to a bowl-shaped damper for internal and external circulation. Background technique [0002] Under the background of increasingly intensified competition in the automobile industry at this stage, major automobile manufacturers are increasingly emphasizing the reliability and comfort of refitting vehicles in order to be in a leading position in the market competition with similar models. Reliability refers to the ability of a product to perform specified functions without failure within a certain period of time and under certain conditions; during the use of a car, it often experiences various working conditions, such as high temperature, low temperature, bumpy road, etc. Wait. Therefore, the higher the reliability of the parts, the more important it is for the continuous trouble-free use of the car. At the same time, high reliability also means low energy consum...
