Description

Technical Field

[0001] The utility model belongs to the field of automobile interior design and relates to a novel blade limiting structure. Background Art

[0002] With the continuous development of the automobile industry, people have higher and higher requirements for the aesthetics and practicality of automobile interiors. At the same time, customers also have high requirements for the blowing angle of the air outlet, which requires automobile interior designers to design more diversified and comfortable interiors. As an indispensable part, the air outlet is extremely important in the automobile interior. When the passenger adjusts the angle of the air outlet during the use of the automobile air outlet, it is easy to adjust the angle too large, and the blade exceeds the blowing limit during the rotation process, causing the blade to get stuck and unable to adjust the blowing angle normally. Therefore, in response to the above problems, a new blade limit structure is applied. Utility Model Content

[0003] The purpose of the utility model is to provide a new blade limiting structure, which enables the air outlet to rotate within an effective blowing angle without getting stuck; it solves the problem that when the passenger adjusts the angle of the air outlet in the car, the angle is easily adjusted too large, and the blades exceed the blowing limit during rotation, causing the blades to get stuck and the blowing angle cannot be adjusted normally.

[0004] The utility model solves the technical problem by adopting the following technical solutions:

[0005] A novel blade limiting structure, comprising: a first upper row of blades 1, a second upper row of blades 2, a third upper row of blades 3, a blade connecting rod 4, and a shell 5, wherein the first upper row of blades 1, the second upper row of blades 2 and the third upper row of blades 3 are respectively coaxially matched with the blade connecting rod 4 and can rotate relative to each other (such as Figure 7 As shown in D), the first upper row blades 1, the second upper row blades 2 and the third upper row blades 3 are respectively connected to the housing 5 by snap-fitting, and the first upper row blades 1, the second upper row blades 2 and the third upper row blades 3 can rotate around the axis C thereon; when the blades rotate, the rotational power is transmitted to the second upper row blades 2, and the first upper row blades 1, the second upper row blades 2 and the third upper row blades 3 are respectively snap-fitted to the blade connecting rod 4, and the second upper row blades 2 drive the first upper row blades 1 and the third upper row blades 3 to rotate, and after reaching a certain angle, the limiting column B on the second upper row blades 2 fits with the limiting boss A on the blade connecting rod 4 to achieve blade limiting and prevent jamming;

[0006] The second upper row of blades 2 is provided with a limiting column B, and the blade connecting rod 4 is provided with a limiting boss A;

[0007] The limiting column B on the second upper row of blades 2 is in zero contact with the limiting boss A on the blade connecting rod 4. In this state, the blades cannot rotate, thus achieving the limiting effect of the blades.

[0008] The advantages and positive effects of the utility model are:

[0009] The utility model has reasonable design, simple structure and convenient operation, and realizes that the air outlet can rotate within an effective blowing angle without getting stuck; it solves the problem that when the passenger adjusts the angle of the air outlet in the car, the angle is easily adjusted too large, the blades exceed the blowing limit during rotation, and the blowing angle cannot be adjusted normally.
