DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 6The utility model provides a dustproof and noise-reducing automobile exterior rearview mirror, comprising a mirror housing 1 and a mirror arm decorative piece 2. A pin shaft 3 is connected to the top of the mirror arm decorative piece 2. The pin shaft 3 penetrates through a through hole 11 provided in the mirror housing 1, and the pin shaft 3 is connected to a dust cover 5 for blocking the through hole 11. The dust cover 5 can block the through hole 11 to prevent dust and other debris from entering the mirror housing 1 during the use of the rearview mirror and the driving of the car, and plays a good role in protecting the internal parts of the mirror housing 1. At the same time, it can protect the vehicle from generating wind noise when driving at high speed. The dust cover 5 is connected to a positioning mechanism for positioning the dust cover 5. The positioning mechanism comprises a shape-changing pressure plate 6, two limiting cylinders 7, two limiting seats 8, and two bolts 13. The limiting cylinder 7 and the limiting seat 8 are connected to the shape-changing pressure plate 6. The limiting cylinder 7 is connected to the mirror housing 1 through the bolts 13. The shape-changing pressure plate 6 is pressed tightly against the dust cover 5. When installing the dust cover 5, the limiting protrusion 9 is inserted into the limiting seat 8, and the positioning column 10 is inserted into the limiting cylinder 7 to achieve preliminary limiting of the shape-changing pressure plate 6, and then the bolt 13 is used to lock the shape-changing pressure plate 6 to the mirror housing 1, so that the shape-changing pressure plate 6 is pressed against the dust cover 5, thereby fixing the dust cover 5, and the operation is simple and convenient.

[0022] The mirror housing 1 is connected with two limiting protrusions 9 and two positioning columns 10. The limiting protrusions 9 match the corresponding limiting seats 8, the positioning columns 10 match the corresponding limiting cylinders 7, the bolts 13 are threadedly connected to the positioning columns 10, the two limiting protrusions 9 are relatively distributed, the two positioning columns 10 are relatively distributed, and the angle between adjacent limiting protrusions 9 and positioning columns 10 is 90 degrees. When installing the dust cover 5, the limiting protrusions 9 and the positioning columns 10 pass through the mounting holes on the dust cover 5 to prevent the dust cover 5 from tilting and deviating, and the installation accuracy is high.

[0023] The pin shaft 3 is fixed with a connecting seat 4 , and the bottom of the connecting seat 4 is connected with a ring plate 12 for limiting the dust cover 5 . The ring plate 12 is provided with a limiting groove 14 , and the limiting groove 14 is connected to the top of the dust cover 5 .

[0024] The dust cover 5 is used to drive the ring plate 12 to move toward the connecting seat 4. The dust cover 5 is made of rubber material and has a certain elasticity. When the dust cover 5 is installed, the dust cover 5 is compressed for a certain displacement so that the top of the dust cover 5 is tightly attached to the limiting groove 14, thereby preventing the mirror housing 1 from having a large gap during the adjustment process, causing dust and other debris to enter the interior of the mirror housing 1.

[0025] The included angle between the two inner surfaces of the limiting groove 14 is 75° to 80°. Figure 6 The middle α, i.e. 75°≤α≤80°, can further prevent the top of the dust cover 5 from leaving the limiting groove 14. The two inner surfaces of the limiting groove 14 are friction surfaces, which increase the contact friction between the dust cover 5 and the limiting groove 14, making the contact position of the dust cover 5 and the limiting groove 14 not easy to slide.

[0026] Working principle: When installing the dust cover 5, the limiting protrusion 9 and the positioning column 10 pass through the mounting hole on the dust cover 5 to limit the dust cover 5, and then the limiting seat 8 docks with the limiting protrusion 9, and the positioning column 10 docks with the limiting cylinder 7 to limit the shape-changing pressure plate 6, and then the bolt 13 is used to lock the shape-changing pressure plate 6, so that the shape-changing pressure plate 6 is pressed against the dust cover 5, and the dust cover 5 is installed and fixed, and the operation is simple and convenient. The top of the dust cover 5 is tightly attached to the ring plate 12, which improves the tightness of the connection between the two, and the through hole 11 is well blocked, which can prevent dust and other debris from entering the interior of the mirror housing 1, and play a good protective role on the internal parts of the mirror housing 1. At the same time, it can protect the vehicle when driving at high speed, suppress the generation of wind noise, and improve driving comfort.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
