[0030] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0031] Example 1

[0032] like Figure 1 、 Figure 2 、 Figure 3 As shown, the external rain-repellent device for a reflector provided in this embodiment includes an air guide duct 1, a connecting buckle 2, a wind shield 3, a bottom plate 4 and a strap 5.

[0033] There are multiple air ducts 1, which are connected in sequence by connecting buckles 2. The air duct 1 includes a first plate 11, a second plate 12 and a third plate 13 connected in sequence. The two ends of the first plate 11, the second plate 12 and the third plate 13 are connected by a fourth plate 14, and the first plate 11 and the third plate 13 are not on the same plane. The enclosed first plate 11, the second plate 12, the third plate 13 and the fourth plate 14 form a channel. The second plate 12 is an arc-shaped plate. The side of the fourth plate 14 away from the third plate 13 is provided with an arc chamfer 141. The arc chamfer 141 may also not be provided on the two fourth plates 13 at the outer ends to facilitate the connection of the windshield 3. The end of the first plate 11 forms an air inlet 15, and the end of the third plate 13 forms an air outlet 16. An aluminum sheet is buried inside the end of the third plate 13 where the air outlet 16 is formed.

[0034] The connector 2 is connected to the fourth plate 14. The connector 2 can be made of a flexible or corrugated plastic structure, such as a flexible tube or bellows, and can be bent to allow the multiple air ducts 1 to conform to the curved upper surface of the reflector housing. Furthermore, the plastic connector 2 can be cut to select the appropriate number of air ducts 1 based on the size of the reflector, improving versatility.

[0035] The wind shield 3 is provided at the two ends of the outermost sides of the plurality of air ducts 1. The extension direction of the wind shield 3 is perpendicular to the connection direction of the plurality of air ducts 1. The wind shield 3 includes a corrugated plate 31, a fifth plate 32 and a sixth plate 33. One end of the corrugated plate 31 is a plate-like structure, which is stacked on the outer surface of the fourth plate 14 of the air duct 1, and the other end of the corrugated plate 31 is connected to the fifth plate 32. The sixth plate 33 is connected to the lower surface of the fifth plate 32. The corrugated plate 31 can be bent to adapt to the back surface of the housing of the reflector. The lower surface of the sixth plate 33 is provided with an adhesive layer. After tearing off the release film of the sixth plate 33, the sixth plate 33 can be fixed to the back of the housing through the adhesive layer. The sixth plate 33 can be arranged only on the lower surface of the fifth plate 32, or can be arranged from the fourth plate 14 on the entire lower end of the corrugated plate 31. In this case, the sixth plate 33 and the corrugated plate 31 need to be bent together, and the corrugated plate 31 and the sixth plate 33 are intermittently connected or not connected to avoid interference between the two when bending.

[0036] The bottom plate 4 is connected to the plurality of fourth plates 14 and is positioned opposite the first plate 11. The bottom plate 4 is capable of bending along with the plurality of air ducts 1. The bottom surface of the bottom plate 4 is in contact with the upper surface of the housing. The bottom plate 4 is made of a deformable and bendable plastic material, and an adhesive layer may be applied to its lower surface depending on the intended use.

[0037] The base plate 4 is provided with a strap 5 for securing the reflector. The strap 5 comprises a first strap 51 and a second strap 52. One end of the first strap 51 is hinged to the base plate 4, while one end of the second strap 52 is hinged to the base plate 4. The first strap 51 is longer than the second strap 52. Both the first strap 51 and the second strap 52 have an adhesive layer.

[0038] The present invention also provides a reflector, comprising a shell for mounting a lens and the above-mentioned external rain-repellent device for the reflector. The base plate 4 is attached to the upper surface of the shell, and the base plate 4 and the plurality of air guide ducts 1 are bent along the curved surface of the upper surface of the shell. The second belt body 52 is attached to the upper surface of the shell from the front side of the reflector, and the end of the second belt body 52 (the end with the aluminum sheet) is inserted between the shell and the lens. The first belt body 51 is attached to the back side of the shell from the rear side of the reflector, and the end of the first belt body 51 (the end with the aluminum sheet) is bent from the lower end of the reflector and inserted between the shell and the lens. The sixth plate 33 on the windshield 3 is attached to the back side of the shell, and the corrugated plate 31 is bent from top to bottom along the back side of the shell. After installation, the first plate 11 in the rain-repellent device is located above the shell, and the third plate 13 is hung above the front side of the mirror.

[0039] Because a metal sheet is embedded in the third plate 13, the metal sheet can be moved to adjust the angle of the third plate 13, thereby adjusting the final air outlet angle of the air guide duct 1, expanding the mirrored air blowing area, and achieving effective rain repellent. The metal sheet can be made of the following materials, which have good ductility and can be easily bent and adjusted by hand: ① aluminum: particularly pure aluminum or softer aluminum alloys such as 1000 series aluminum alloys; ② copper: pure copper (such as C10100) and some softer copper alloys (such as brass); ③ lead; ④ tin; ⑤ zinc; ⑥ certain low-alloy steels: some low-alloy steels, especially those that have been annealed.

[0040] The flexible strap 5 makes installation more flexible, and combined with the first strap body 51 and the second strap body 52, the rain repellent device is installed more firmly, ensuring that the risk of falling off can be avoided even when encountering strong winds or driving on highways.

[0041] The corrugated panels 31 can be stretched to varying degrees, significantly reducing stress concentration in the plastic. The adhesive layer of the sixth panel 33 also ensures a more secure and secure attachment of the windshield panels 3 on both sides. The windshield panels 3 effectively guide the air generated by the vehicle's forward motion and natural wind from the air inlet into the air guide duct 1, reducing air loss on both sides and allowing the air inlet to collect more air, thereby increasing the air volume at the air outlet and creating a more pronounced mirror-like rain-repelling effect.

[0042] Example 2

[0043] Repeat Example 1, except that Figure 4 As shown, the outer surface of the third plate 13 is provided with a rain shield 6, and the rain shield 6 is bent outward. When it rains, the rain shield 6 prevents rainwater from flowing along the third plate 13 and remaining on the mirror surface of the reflector.

[0044] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
