Description

Technical Field

[0001] The utility model belongs to the field of automobile interior design and relates to a novel blade structure, in particular to a novel blade structure for preventing air outlet whistling. 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, which requires automobile interior designers to design more diversified and personalized interiors. The air outlet blades are an important part of the automobile air outlet and are extremely important in the automobile interior. When the automobile air outlet is used, it is easy to produce whistling, which affects the customer experience. In view of this, there is an urgent need for a structure with a simple structure, reasonable design, and the ability to achieve the normal operation of the air outlet blades without whistling. Utility Model Content

[0003] The utility model aims to provide a novel blade structure for preventing air outlet whistling, thereby solving the problem that the air outlet in the original automobile interior is prone to whistling during use.

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

[0005] A novel blade structure for preventing whistling at an air outlet comprises: a first blade 1, a second blade 2, a third blade 3, a fourth blade 4, a fifth blade 5, a sixth blade 6, a seventh blade 7, a blade bracket 8, a blade connecting rod 9 and a shell 10, wherein the first blade 1, the second blade 2, the third blade 3, the fourth blade 4, the fifth blade 5, the sixth blade 6 and the seventh blade 7 are connected to the blade bracket 8 by snap-fitting, the first blade 1, the second blade 2, the third blade 3, the fourth blade 4, the fifth blade 5, the sixth blade 6 and the seventh blade 7 are connected to the blade connecting rod 9 by snap-fitting, and the blade connecting rod 9 is connected to the shell 10 by snap-fitting. When working, the sixth blade 6 will obtain a transmission force, and the first blade 1, the second blade 2, the third blade 3, the fourth blade 4, the fifth blade 5, the sixth blade 6 and the seventh blade 7 are connected to the blade connecting rod 9, so when the sixth blade 6 obtains the transmission force and rotates, it will drive other blades to rotate.

[0006] The first blade 1, the second blade 2, the third blade 3, the fourth blade 4, the fifth blade 5, the sixth blade 6, and the seventh blade 7 are made of soft rubber material;

[0007] In the closed state, the soft rubber structure of the traditional blade is too deep, and there is a step on the other blade. When the wind passes through the blade, it will be directed into the pit of the soft rubber, forming a vortex and producing a whistle sound (such as Figure 5 , Figure 6 As shown); the soft rubber non-sealing surface of the blade has a relatively flat pit, which can effectively avoid the formation of vortexes and the generation of whistling (as shown Figure 7 , Figure 8 shown).

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

[0009] The utility model has reasonable design, stable and reliable structure, and can effectively prevent the air outlet from whistling during use, and has broad market prospects and application value. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0019] 1. See Figure 1-Figure 8, a new blade structure for preventing whistling at the air outlet according to the specific embodiment of the present invention comprises: a first blade 1, a second blade 2, a third blade 3, a fourth blade 4, a fifth blade 5, a sixth blade 6, a seventh blade 7, a blade bracket 8, a blade connecting rod 9 and a shell 10, wherein the first blade 1, the second blade 2, the third blade 3, the fourth blade 4, the fifth blade 5, the sixth blade 6 and the seventh blade 7 are connected to the blade bracket 8 by snap-fitting, the first blade 1, the second blade 2, the third blade 3, the fourth blade 4, the fifth blade 5, the sixth blade 6 and the seventh blade 7 are connected to the blade connecting rod 9 by snap-fitting, and the blade connecting rod 9 is connected to the shell 10 by snap-fitting. When working, the sixth blade 6 will obtain a transmission force, and the first blade 1, the second blade 2, the third blade 3, the fourth blade 4, the fifth blade 5, the sixth blade 6 and the seventh blade 7 are connected to the blade connecting rod 9, so when the sixth blade 6 obtains a transmission force and rotates, it will drive other blades to rotate.

[0020] The first blade 1, the second blade 2, the third blade 3, the fourth blade 4, the fifth blade 5, the sixth blade 6, and the seventh blade 7 are made of soft rubber material;

[0021] In the closed state, the soft rubber structure of the traditional blade is too deep, and there is a step on the other blade. When the wind passes through the blade, it will be directed into the pit of the soft rubber, forming a vortex and producing a whistle sound (such as Figure 5 , Figure 6 As shown); the soft rubber non-sealing surface of the blade has a relatively flat pit, which can effectively avoid the formation of vortexes and the generation of whistling (as shown Figure 7 , Figure 8 shown).

[0022] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
