Description

Technical Field

[0001] This utility model belongs to the field of automotive air vent trim design technology, specifically a noise reduction structure for automotive air vent horizontal blade trim. Background Technology

[0002] The horizontal blade trim of a car's air vent is a component of the car's interior. It is usually installed on the horizontal blades of the car's air conditioning vents, serving both decorative and functional purposes. The trim is generally long and can be designed and made of different materials to add beauty and texture to the car's interior.

[0003] Existing automotive air vent horizontal blade trim strips are generally fixed to the air vent blades with an internal frame. During daily use, the trim strip is prone to vibration caused by the airflow from the car's air conditioning, resulting in noise. Since the air vents are located directly in front of the front-seat users, this noise is easily perceived by the users, indicating room for improvement.

[0004] Therefore, this utility model provides a noise reduction structure for horizontal blade trim strips on automotive air vents. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0010] Preferably, the first built-in spring, the fixing strip, the clamp, and the second built-in spring are made of martensitic stainless steel. The above-mentioned use of martensitic stainless steel for the first built-in spring, the fixing strip, the clamp, and the second built-in spring enhances their structural strength and elasticity, which is beneficial to improving the fixing firmness of the trim structure and extending the service life of the trim structure.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown in the figure, a noise reduction structure for a horizontal blade trim strip of an automotive air vent according to an embodiment of the present invention includes an air vent blade 1 and a trim strip 11, the trim strip 11 being sized to correspond to the air vent blade 1; a first internal spring piece 12 is fixedly connected inside the trim strip 11; a first clamping block 13 and a second clamping block 14 are fixedly connected to the inner side wall of the trim strip 11, and the first clamping block 13 and the second clamping block 14 are arranged in parallel; a fixing strip 15 is fixedly connected to the side wall of the first internal spring piece 12, and the fixing strip 15 passes through the end of the trim strip 11; fixing... A clamp 16 is fixedly connected to the end of the strip 15; the clamp 16 is configured to correspond to the size of the air outlet blade 1; during operation, the first built-in spring piece 12 fixed inside the decorative strip 11 provides elasticity to the decorative strip 11. Since the multiple first built-in spring pieces 12 do not contact each other, whenever one of the first built-in spring pieces 12 vibrates due to wind force, the vibration cannot be directly transmitted to the adjacent first built-in spring piece 12. Whenever it is necessary to install the horizontal blade trim on the air outlet blade 1, the user can align the decorative strip 11 with the air outlet blade 1. A pushing force is applied to the decorative strip 11. During this process, the decorative strip 11 and the first built-in spring 12 will deform under the pressure of the air outlet blade 1. The first clamping block 13 and the second clamping block 14, which are fixed to the inner wall of the decorative strip 11, will also deform. The user can continue to push the decorative strip structure until the inner wall of the decorative strip 11 is in complete contact with the outer side of the air outlet blade 1. At this time, the decorative strip 11 will be clamped to the side wall of the air outlet blade 1 under the elastic force of the first built-in spring 12, and the first clamping block 13 and the second clamping block 14 will also deform. The first built-in spring 12 will also be in close contact with the side wall of the air outlet blade 1 under the elastic force of the first built-in spring 12. The clamp 16 fixed to the end of the fixing strip 15 is in direct contact with the side wall of the air outlet blade 1. Through the above structure, multiple non-adjacent first built-in springs 12 are provided with elastic force for the decorative strip 11, thereby fixing the decorative strip 11 to the side wall of the air outlet blade 1. At the same time, the non-adjacent nature of multiple first built-in springs 12 is used to isolate the vibration on a single first built-in spring 12, which helps to alleviate resonance and reduce the noise of the decorative strip.

[0026] like Figures 1 to 5As shown, an arc-shaped extension block 2 is fixedly connected to the side wall of the decorative strip 11; a side plate 21 is fixedly connected to the side wall of the arc-shaped extension block 2, and the side plate 21 is sized to correspond to the air outlet blade 1; a third clamping block 22 is fixedly connected to the inner side wall of the arc-shaped extension block 2; a second built-in spring piece 23 is fixedly connected inside the arc-shaped extension block 2, and the second built-in spring piece 23 is sized to correspond to the arc-shaped extension block 2; during operation, the second built-in spring piece 23 fixed inside the arc-shaped extension block 2 can provide elasticity to the arc-shaped extension block 2. At the same time, the second built-in spring piece 23 does not contact the first built-in spring piece 12, and vibration cannot be directly transmitted between the second built-in spring piece 23 and the first built-in spring piece 12. Meanwhile, whenever the car air conditioner is working, the airflow at the edge of the air vent will be blocked by the side wall of the side panel 21 and will not be able to enter the interior of the arc-shaped extension block 2. When the trim structure is installed, the third clamping block 22 will be in close contact with the side wall of the air vent blade 1 under the elastic force of the second built-in spring 23. Through the above structure, the arc-shaped extension block 2 and the side panel 21 are set to block the edge airflow of the car air vent, preventing the edge airflow from entering between the air vent blade 1 and the trim strip 11, thereby reducing wind resistance and noise. At the same time, the third clamping block 22 and the second built-in spring 23 are set to improve the stability of the trim structure and help prevent the trim from falling off.

[0027] like Figure 1 and Figure 5 As shown, a first limiting block 3 is fixedly connected to the top of the decorative strip 11, and the two first limiting blocks 3 are arranged correspondingly; a second limiting block 31 is fixedly connected to the bottom of the decorative strip 11, and the two second limiting blocks 31 are arranged corresponding to the positions of the first limiting blocks 3; during operation, when the operator adjusts the angle of the air outlet blade 1, the first limiting block 3 fixed to the top of the decorative strip 11 and the second limiting block 31 fixed to the bottom of the decorative strip 11 can contact each other to prevent adjacent decorative strips 11 from contacting, thereby maintaining the normal airflow of the car's air outlet and preventing blockage of the car's air outlet; through the above structure, the first limiting block 3 and the second limiting block 31 are set to prevent adjacent decorative strips 11 from contacting during the angle adjustment of the air outlet blade 1, which is conducive to maintaining smooth airflow from the car's air outlet and enhances the practicality and convenience of the decorative strip structure.

[0028] like Figure 4As shown, a first through hole 4 is provided on the side wall of the first built-in spring piece 12, and multiple first through holes 4 are arranged correspondingly; a second through hole 41 is provided on the side wall of the second built-in spring piece 23, and multiple second through holes 41 are arranged correspondingly. During operation, since multiple first through holes 4 and multiple second through holes 41 are provided on the side walls of the first built-in spring piece 12 and the second built-in spring piece 23 respectively, the contact area between the decorative strip 11 and the first built-in spring piece 12 and the contact area between the arc-shaped extension block 2 and the second built-in spring piece 23 will increase. Through the above structure, the first through holes 4 and the second through holes 41 are provided so that the decorative strip 11 and the arc-shaped extension block 2 can be fitted with the first built-in spring piece 12 and the second built-in spring piece 23 respectively, which enhances the stability of the structure, helps to prevent the first built-in spring piece 12 and the second built-in spring piece 23 from falling off, and improves the service life of the decorative strip structure.

[0029] like Figure 4 As shown, the first built-in spring 12, fixing strip 15, clamp 16, and second built-in spring 23 are made of martensitic stainless steel. During operation, the first built-in spring 12, fixing strip 15, clamp 16, and second built-in spring 23, made of martensitic stainless steel, leverage their advantages of high structural strength and elasticity. Through the above, the use of martensitic stainless steel for the first built-in spring 12, fixing strip 15, clamp 16, and second built-in spring 23 enhances their structural strength and elasticity, which is beneficial to improving the fixing firmness of the decorative strip structure and extending its service life.

[0030] like Figure 3 As shown, the decorative strip 11, the first clamping block 13, the second clamping block 14, the arc-shaped extension block 2, and the third clamping block 22 are made of plastic. During operation, the use of plastic materials in the decorative strip 11, the first clamping block 13, the second clamping block 14, the arc-shaped extension block 2, and the third clamping block 22 allows them to take advantage of the high toughness and high surface friction coefficient of plastic. Through the above, the use of plastic materials in the decorative strip 11, the first clamping block 13, the second clamping block 14, the arc-shaped extension block 2, and the third clamping block 22 enhances their toughness and friction coefficient, which is beneficial to improving the stability of the decorative strip structure and preventing the decorative strip structure from falling off.

[0031] like Figure 1 As shown, an electroplated layer is provided on the outer wall of the decorative strip 11 and the arc-shaped extension block 2. During operation, the electroplated layer on the outer wall of the decorative strip 11 and the arc-shaped extension block 2 can effectively improve the surface smoothness and scratch resistance of the decorative strip 11 and the arc-shaped extension block 2. Through the above, the electroplated layer on the surface of the decorative strip 11 and the arc-shaped extension block 2 improves the surface smoothness and scratch resistance of the decorative strip 11 and the arc-shaped extension block 2, giving them a metallic luster, which is beneficial to enhancing the durability of the decorative strip structure.

[0032] During operation, the first built-in spring piece 12 fixed inside the decorative strip 11 provides elasticity to the decorative strip 11. Since the multiple first built-in spring pieces 12 do not contact each other, whenever one of the first built-in spring pieces 12 vibrates due to wind, the vibration cannot be directly transmitted to the adjacent first built-in spring pieces 12. Whenever it is necessary to install the horizontal blade trim on the air outlet blade 1, the user can align the decorative strip 11 with the air outlet blade 1 and apply a pushing force to the decorative strip 11. During the process, the decorative strip 11 and the first built-in spring piece 12 will deform under the compression of the air outlet blade 1, and the first clamping block 13 and the second clamping block 14 fixed on the inner wall of the decorative strip 11 will also deform. The user can continuously push the trim structure. Until the inner wall of the decorative strip 11 is fully in contact with the outer side of the air outlet blade 1, the decorative strip 11 will be clamped onto the side wall of the air outlet blade 1 under the elastic force of the first built-in spring 12, and the first clamping block 13 and the second clamping block 14 will also be in close contact with the side wall of the air outlet blade 1 under the elastic force of the first built-in spring 12. The clamp 16 fixed to the end of the fixing strip 15 directly contacts the side wall of the air outlet blade 1. The second built-in spring 23 fixed inside the arc-shaped extension block 2 provides elasticity to the arc-shaped extension block 2. At the same time, the second built-in spring 23 does not contact the first built-in spring 12, so vibration cannot be directly transmitted between the second built-in spring 23 and the first built-in spring 12. Also, whenever the car... When the air conditioner is working, the airflow at the edge of the air outlet will be blocked by the side wall of the side panel 21 and will not be able to enter the interior of the arc-shaped extension block 2. After the trim structure is installed, the third clamping block 22 will be in close contact with the side wall of the air outlet blade 1 under the elastic force of the second built-in spring 23. During the adjustment of the angle of the air outlet blade 1, the first limiting block 3 fixed to the top of the trim strip 11 and the second limiting block 31 fixed to the bottom of the trim strip 11 can contact each other to prevent adjacent trim strips 11 from contacting, thereby maintaining normal airflow from the car's air outlet and preventing blockage. Multiple first through holes 4 are respectively opened on the side walls of the first built-in spring 12 and the second built-in spring 23 to... The multiple second through holes 41 will increase the contact area between the decorative strip 11 and the first built-in spring 12, as well as the contact area between the arc-shaped extension block 2 and the second built-in spring 23. The first built-in spring 12, the fixing strip 15, the clamp 16, and the second built-in spring 23, made of martensitic stainless steel, will take advantage of their high structural strength and elasticity. The decorative strip 11, the first clamping block 13, the second clamping block 14, the arc-shaped extension block 2, and the third clamping block 22, made of plastic, will take advantage of the plastic material's high toughness and high surface friction coefficient. The electroplating layer on the outer wall of the decorative strip 11 and the arc-shaped extension block 2 will effectively improve the surface smoothness and scratch resistance of the decorative strip 11 and the arc-shaped extension block 2.
