Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive component technology, and in particular to an automotive rearview mirror. Background Technology
[0002] Car rearview mirrors are usually fitted with a guide frame, and grooves are made in the guide frame so that rainwater can be discharged to both sides from the grooves, preventing rainwater from flowing directly onto the mirror and causing visual interference.
[0003] In the current technology, some car models, in order to pursue low energy consumption, will set the rearview mirrors to an aerodynamic shape, with a raised middle and downward tilted ends when viewed from the side. This makes it easier for water to flow from the rearview mirror shell to the lens. With just grooves, the lens of the rearview mirror will still get wet more easily than the lens of a regular rearview mirror in heavy rain. If the guide frame is thickened, some energy will be lost, which is not conducive to the realization of aerodynamics. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a car rearview mirror, which aims to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0006] A car rearview mirror includes a rearview mirror body and a guide frame disposed on the edge of the rearview mirror body. The guide frame includes a connecting portion connected to the rearview mirror body, a guide portion disposed at an angle to the connecting portion, and a transition portion located between the connecting portion and the guide portion. The connecting portion is inclined outward from the rearview mirror body towards the transition portion. The guide portion is inclined outward from the transition portion towards the rearview mirror body towards the side away from the connecting portion. A guide groove is recessed in the guide portion. The guide groove has a straight section and inclined sections located on both sides of the straight section. The straight section and the inclined sections also have grooves.
[0007] According to one aspect of the above technical solution, the rearview mirror body includes a housing, a reflector disposed on the housing, and an extension disposed on the edge of the housing.
[0008] According to one aspect of the above technical solution, the side of the guide frame near the rearview mirror body is provided with an embedding groove into which the extension is partially embedded, and the extension is glued to the embedding groove.
[0009] According to one aspect of the above technical solution, the horizontal tilt angle of the connecting part and the guide part is 5° to 8°.
[0010] According to one aspect of the above technical solution, the inclined segment extends from the straight segment in a direction away from the rearview mirror body, and the connection between the straight segment and the inclined segment is chamfered.
[0011] According to one aspect of the above technical solution, the groove includes a parallel groove arranged parallel to the straight section and an inclined groove arranged parallel to the inclined section, wherein the connection between the parallel groove and the inclined groove is chamfered.
[0012] According to one aspect of the above technical solution, the depth of the trench is 1mm to 2mm, and the depth of the guide groove is 2mm to 4mm.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention reduces wind resistance and drains rainwater by setting a guide frame on the rearview mirror body. Specifically, in dry weather, the guide frame reduces wind resistance. The airflow climbs up and down the rearview mirror body to the guide frame, and then continues to climb along the joint. When it reaches the straight section from the transition section, it touches the groove wall of the straight section and then flows to the inclined sections on both sides. After reaching the inclined section, it flows forward to both sides along the inclined section until it breaks through the inclined section and is guided to the rear of the rearview mirror body. This design meets aerodynamic requirements. When it rains, the rainwater dripping in the guide groove hits the groove and flows outward like airflow, preventing rainwater from flowing into the rearview mirror.
[0015] This invention allows airflow to transition more effectively to the guide channel through the inclined section design, avoiding the obstruction of airflow by the original guide frame. At the same time, the design of the guide channel and groove enables the guide frame to have a drainage function, and can also reduce wind resistance while conforming to aerodynamics.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Please see Figures 1 to 5 The image shows a car rearview mirror according to a first embodiment of the present invention, including a rearview mirror body 10 and a guide frame 20 disposed on the edge of the rearview mirror body 10. The guide frame 20 includes a connecting part 23 connected to the rearview mirror body 10, a guide part 24 disposed at an angle to the connecting part 23, and a transition part 22 located between the connecting part 23 and the guide part 24. The connecting part 23 is inclined outward from the rearview mirror body 10 towards the transition part 22. The guide part 24 is inclined outward from the transition part 22 towards the side away from the connecting part 23 towards the rearview mirror body 10. A guide groove is recessed in the guide part 24. The guide groove has a straight section 25 and inclined sections 26 located on both sides of the straight section 25. The straight section 25 and the inclined section 26 also have grooves.
[0028] Understandably, this utility model reduces wind resistance and drains rainwater by setting a guide frame 20 on the rearview mirror body 10. Specifically, in dry weather, the guide frame 20 reduces wind resistance. After the airflow climbs up and down to the guide frame 20 from the rearview mirror body 10, it continues to climb along the connecting part 23. When it reaches the straight section 25 from the transition part 22, it touches the groove wall of the straight section 25 and then flows to the inclined sections 26 on both sides. After reaching the inclined section 26, it flows forward to both sides along the inclined section 26 until it breaks through the inclined section 26 and is guided to the rear of the rearview mirror body 10. This design satisfies aerodynamics. When it rains, the rainwater dripping in the guide groove hits the groove and flows to the outside like airflow, preventing rainwater from flowing to the rearview mirror.
[0029] The design of the inclined part allows the airflow to transition to the guide groove better, avoiding the obstruction of the airflow by the original guide frame 20. At the same time, the design of the guide groove and channel makes the guide frame 20 have the function of drainage, and can also reduce wind resistance while conforming to aerodynamics.
[0030] Specifically, in this embodiment, the rearview mirror body 10 includes a housing, a reflector disposed on the housing, and an extension 11 disposed on the edge of the housing.
[0031] Understandably, the extension 11 exists to shield the rearview mirror from rainwater and prevent it from flowing directly onto the mirror. However, this is insufficient for heavy rainfall or for rearview mirrors with special shapes.
[0032] Furthermore, the side of the guide frame 20 near the rearview mirror body 10 has an embedding groove 21 into which the extension 11 is partially embedded, and the extension 11 is glued to the embedding groove 21. In other preferred embodiments, in addition to glue, it can also be fixed by bolts or other means.
[0033] Specifically, the horizontal tilt angle of the connecting part 23 and the guide part 24 is 5° to 8°.
[0034] It is understandable and preferred that the tilt angle of the guide section 24 is slightly greater than that of the connecting section 23, so that the airflow can transition from the connecting section 23 to the guide section 24 in an orderly manner, and then flow out of the guide section 24 more quickly.
[0035] Furthermore, the inclined segment 26 extends from the straight segment 25 in a direction away from the rearview mirror body 10, and the connection 23 between the straight segment 25 and the inclined segment 26 is chamfered; the groove includes a parallel groove 27 arranged parallel to the straight segment 25 and an inclined groove 28 arranged parallel to the inclined segment 26, and the connection 23 between the parallel groove 27 and the inclined groove 28 is chamfered.
[0036] Understandably, there are two straight sections 25, which are only set on the upper and lower sides of the guide frame 20. Since there is no need for drainage on the side of the shell, rainwater will not flow from the side onto the reflector. The function of reducing wind resistance is achieved only through the connecting part 23 and the guide part 24. The upper and lower sides of the reflector are the key areas for rainwater intrusion. Taking the upper part of the reflector as an example to illustrate the principle: When the airflow flows from the connecting part 23 to the guide part 24, the airflow located on the upper side of the reflector will flow directly out from the inclined surface of the guide part 24. The rainwater will flow down from the guide part 24 into the inclined groove 28 of the guide channel, and then be discharged to the sides of the reflector along the groove. The airflow located in the middle of the upper part of the reflector will enter the straight section 25, and then flow along the sides of the straight section 25 to the inclined section 26 to achieve the guiding function. The rainwater will enter the parallel groove 27 from the straight section 25, and then flow along the sides of the parallel groove 27 to the inclined groove 28 to discharge the rainwater. The purpose of setting the connection 23 between the straight section 25 and the inclined section 26 at an angle is to reduce airflow loss and reduce wind resistance. The purpose of setting the connection 23 between the parallel groove 27 and the inclined groove 28 at an angle is to facilitate smoother rainwater drainage.
[0037] Preferably, the depth of the trench is 1mm to 2mm, and the depth of the guide groove is 2mm to 4mm.
[0038] The actual depth can be determined according to the usage requirements. For example, in order to prevent mud and water from being unable to drain, the depth of the drainage channel is made larger for off-road vehicles.
[0039] In summary, the car rearview mirror in the above embodiments of this utility model allows airflow to transition better to the guide groove through the design of the inclined part, avoiding the obstruction of airflow by the original guide frame. At the same time, the design of the guide groove and channel makes the guide frame have the function of drainage, and can also reduce wind resistance while conforming to aerodynamics.
