The wind guide mechanism includes a primary blade and a secondary blade rotatably arranged in the housing. The knob is arranged between the primary blade and the secondary blade. The knob is provided with a damping member fixedly arranged on the inner side wall of the knob. The damping member is in contact with the inner side wall of the primary blade. When the knob slides along the primary blade, the friction between the damping member and the primary blade generates a damping force, thereby providing an operation feeling. The damping member is made of silica gel, which facilitates the assembly of the damping member and makes the damping member easy to deform, thereby generating a damping force. However, since the damping member is made of silica gel, if the air blown out of the automobile air outlet is cold air, the moisture in the air will condense into condensate water on the surface of the blade due to the high temperature inside the automobile. Moreover, the damping member is fixed on the knob. When the knob moves, the damping member moves relative to the blade. In the process of rapidly rotating the knob, due to the condensate water on the blade, the damping member sticks and slides relative to the blade, and the sticking and sliding phenomenon alternately and repeatedly occurs, thereby causing a stick-slip phenomenon. The stick-slip phenomenon causes the frictional movement between the damping member and the blade to produce an abnormal sound of "squeak", which has the problem of abnormal noise and poor user experience.

[0024] The utility model discloses a specific implementation of automobile air outlet anti-abnormal sound damping structure, please see Figures 1 to 2 , and the damping mounting structure includes dial assembly 1, damping piece 3 and blade 2.

[0025] Dial assembly 1 is equipped with the sliding channel 10 of arranging along the transverse direction, and blade 2 is worn in the sliding channel 10. Figure 3 Specifically, in combination with Dial assembly 1 includes dial body 11 and dial seat 12.Dial body 11 is equipped with multiple pawls 61 that extend towards dial seat 12, and dial seat 12 is equipped with multiple clamping holes 62 that correspond to each pawl 61.When installed, the pawls 61 are inserted into the corresponding clamping holes 62 and hooked behind dial seat 12 to form a detachable connection structure between dial body 11 and dial seat 12.Further, the upper and lower parts of the end face of dial body 11 towards dial seat 12 extend pawls 61, and correspondingly, the upper and lower parts of dial seat 12 are also equipped with clamping holes 62 that match each pawl 61 one by one, making the clamping connection of dial body 11 and dial seat 12 more stable and reliable.

[0026] In some embodiments, the positions of the pawls 61 and the clamping holes 62 can be interchanged or cross-set, for example, the end face of dial seat 12 towards dial body 11 extends pawls 61 outward, and correspondingly, the end face of dial body 11 towards dial seat 12 is provided with clamping holes 62 that match the pawls 61, or the end face of dial seat 12 towards dial body 11 extends pawls 61 and clamping holes 62 outward, and correspondingly, the end face of dial body 11 towards dial seat 12 is provided with clamping holes 62 and pawls 61, and when assembled, the pawls 61 can be inserted into the corresponding clamping holes 62.

[0027] Figure 3 In this embodiment, as shown in The end face of dial body 11 towards dial seat 12 is provided with a first groove 51, the end face of dial seat 12 towards dial body 11 is provided with a second groove 52, the first groove 51 and the second groove 52 are oppositely arranged, and when the dial body 11 and the dial seat 12 are clamped and connected, the first groove 51 and the second groove 52 are mutually communicated to form the sliding channel 10.

[0028] Figure 2 As shown in In order to improve the operation fluency of blade 2, the end face of blade 2 towards the second groove 52 extends a strip-shaped body 21 outward, and when blade 2 is inserted into the sliding channel 10, the strip-shaped body 21 is inserted into the second groove 52, so that the strip-shaped body 21 can slide along the second groove 52, and the sliding cooperation between the strip-shaped body 21 and the second groove 52 can play a guiding and limiting role, preventing blade 2 from deviating and improving operation fluency and operation stability.

[0029] Figure 3 Figure 4 ​As shown, the inner wall of the sliding channel 10 is recessed to form a clamping groove 53, that is, the groove bottom of the first groove 51 is provided with an inner recessed clamping groove 53, and the damping member 3 is clamped in the clamping groove 53. It can be understood that the cooperation between the damping member 3 and the clamping groove 53 is an interference fit. The damping member 3 and the blade 2 are provided with an anti-rust layer 4, wherein the anti-rust layer 4 can be bonded and fixed to the end face of the blade 2 in contact with the damping member 3. The anti-rust layer 4 is a sheet structure made of Teflon. In some embodiments, the anti-rust layer 4 can also be bonded and fixed to the area of the blade 2 in contact with the damping member 3, that is, the anti-rust layer 4 is fixed to the outer surface of the blade 2, or the anti-rust layer 4 is not only bonded and fixed to the end face of the damping member 3, but also bonded and fixed to the outer surface of the blade 2. By setting two layers of anti-rust layer 4 to isolate the blade 2 and the damping member 3, direct contact between the blade 2 and the damping member 3 is avoided to prevent abnormal noise.

[0030] In combination Figure 4 In the assembled state, the blade 2 is inserted into the sliding channel 10 and can slide along the sliding channel 10, and the damping member 3 located in the clamping groove 53, wherein the upper end face abuts against the groove bottom of the clamping groove 53, and the lower end face abuts against the anti-rust layer 4, so that the anti-rust layer 4 tightly abuts against the outer side face of the blade.

[0031] The anti-rust layer 4 is a sheet structure made of Teflon. Teflon is a long-chain molecule composed of carbon atoms and fluorine atoms. The fluorine atoms almost cover the entire surface, forming a very smooth surface, making it difficult for condensed water to adhere to it. The surface energy of Teflon is very low, and it is not easy to interact with other substances, thereby reducing the possibility of its adhesion to condensed water. In addition, Teflon can remain stable in a temperature range of -200 to 260 degrees, and even at extreme high or low temperatures (air conditioner extreme temperature working condition), it will not undergo chemical changes, thereby ensuring that its non-stick properties will not decrease, and it can maintain good performance in low and high temperature environments, with strong stability and long service life. In addition, the friction coefficient of Teflon is very low, which not only helps its non-stick property, but also reduces wear and tear and improves wear resistance, further improving the service life of the damping structure.

[0032] The anti-rust damping structure of the present embodiment sets an anti-rust layer 4 between the damping member and the blade, and the anti-rust layer 4 is a sheet structure made of Teflon. The anti-rust layer 4 made of Teflon can form a very smooth surface, making the anti-rust layer 4 have high lubricity and non-stick properties, so that it is difficult for condensed water to adhere to the anti-rust layer 4, thereby avoiding the stick-slip phenomenon when the damping member 3 and the blade 2 move relative to each other, and solving the problem of abnormal noise caused by friction between the damping member 3 and the blade 2.

[0033] In the embodiment, the damping member 3 is a silica gel member, and the damping member 3 is fixedly bonded with the anti-rust layer 4. Specifically, the damping member 3 and the anti-rust layer 4 can be integrally bonded by means of adhesive (glue) or by means of molding. The damping member 3 extends outward from the end face facing the blade 2 in a pair of spaced-apart protrusions 31, so that the end face of the damping member 3 is arranged in a concave shape, and the anti-rust layer 4 is arranged in a few shapes on the concave end face of the damping member 3. Since the two protrusions 31 are spaced apart, a certain space is left between the two protrusions 31, which is beneficial to the deformation of the protruding part of the damping member 3, avoids the problem of jamming of the damping member 3, and is more convenient for assembly of the damping member 3.

[0034] See Figure 3 The clamping groove 53 is formed in the groove bottom of the first groove 51, and the clamping groove 53 is arranged in a rectangular shape, which is more convenient for clamping the damping member 3. In some embodiments, the clamping groove 53 can be circular or elliptical or triangular or various shapes, as long as the clamping groove 53 can accommodate a part of the damping member 3, so as to limit the movement of the damping member 3.

[0035] In the embodiment, an automobile air outlet includes an air outlet frame, a plurality of anti-rust damping structures described above are installed in the air outlet frame, and a plurality of blades 2 are rotatably installed on the air outlet frame. By rotating the knob assembly 1, the corresponding blade 2 can be driven to rotate, thereby adjusting the air outlet direction.

[0036] Finally, it should be noted that: the automobile air outlet anti-rust damping structure disclosed in the embodiment of the utility model is only a preferred embodiment of the utility model, and is used to illustrate the technical scheme of the utility model, but not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; the technical scheme recorded in the foregoing embodiments can be modified, or some technical features can be replaced; and these modifications or replacements do not make the essence of the corresponding technical scheme deviate from the spirit and scope of the technical scheme of the utility model embodiments.
