Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an exterior rearview mirror for monitoring blind spots in vehicles. Background Technology

[0002] Car side mirrors are crucial components for ensuring driving safety, but traditional designs have blind spots, especially when changing lanes or turning, easily leading to accidents because vehicles to the side and rear are not noticed. To solve this problem, auxiliary mirrors have been added to the side mirrors, such as using convex, high-curvature wide-angle lenses to expand the field of vision and cover areas that the original side mirrors cannot illuminate (such as near the wheels and blind spots to the side and rear), effectively reducing the risk of scratches and collisions.

[0003] Existing blind spot auxiliary rearview mirrors are usually small convex circular mirrors that are attached to the rearview mirror. The angle of the auxiliary circular mirror is usually fixed, which makes it difficult to adapt to different usage needs. In addition, the auxiliary circular mirror is usually a one-sided mirror structure. When the convex mirror is damaged by external forces such as flying stones, there is no replacement, which makes it difficult to use in emergency scenarios such as high-speed driving. At the same time, the whole thing needs to be replaced, which is a waste of costs.

[0004] Therefore, there is a need for a vehicle exterior rearview mirror that monitors blind spots to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to provide a car exterior rearview mirror for monitoring blind spots, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vehicle exterior rearview mirror for monitoring blind spots includes a housing. Inside the housing, there is a mounting plate located at the port of the housing. Convex lenses are fixedly attached to both sides of the mounting plate. Two coaxially arranged shafts are fixed to the sides of the mounting plate. The shafts are rotatably disposed through the side wall of the housing. The ends of the shafts are provided with positioning components for locking the angle of the convex lenses.

[0008] It should be noted in the solution that the positioning component includes an end plate fixed to the end of one of the shafts. The end plate has multiple equidistant protrusions fixed on its cylindrical side. The outer side wall of the housing has a protrusion plate fixed to it. The side of the protrusion plate has a metal spring piece fixed to it. The end of the metal spring piece is engaged between two adjacent protrusions to lock the end plate.

[0009] It is worth noting that another shaft has a rotating head plate fixed to its end, and the rotating head plate has multiple ribs arranged in a ring on its column side.

[0010] Furthermore, it should be noted that the outer casing has multiple drainage holes on its side, and these drainage holes are evenly distributed.

[0011] Preferably, an M-adhesive is attached and fixed to the bottom surface of the outer shell, and a rubber sleeve is attached and fitted to the outer surface of the rotating head plate.

[0012] Compared with the prior art, the automotive exterior rearview mirror for monitoring blind spots provided by this utility model has at least the following beneficial effects:

[0013] 1. By rotating the shaft and the side wall of the housing, the tilt angle of the mounting plate can be adjusted according to usage requirements, allowing the convex lens to be easily rotated and adjusted to different tilt angles, effectively improving the performance of the convex lens.

[0014] 2. The positioning component is used to position and lock the convex lens after the tilt angle is adjusted, which improves the stability of the convex lens after the tilt angle is adjusted, maintains the stability of the driver's field of vision, reduces the driver's distraction from frequently adjusting the convex lens, and enhances driving safety.

[0015] 3. When one of the convex lenses is damaged by external forces such as flying stones, the mounting plate can be turned over and flipped to expose the convex lens on the other side of the mounting plate. This allows the two convex lenses to be used interchangeably, enabling temporary replacement of the broken convex lens without requiring immediate replacement of the entire lens or the whole device. This is especially suitable for emergency scenarios such as high-speed driving, while also reducing the waste caused by the failure of a single lens and saving costs. Attached Figure Description

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-6 This utility model provides a car exterior rearview mirror for monitoring blind spots, including a housing 3. Inside the housing 3, a mounting plate 4 is located at the port of the housing 3. Convex lenses 2 are fixedly attached to both sides of the mounting plate 4. Two coaxially arranged shafts 5 are fixed to the sides of the mounting plate 4. The shafts 5 rotatably pass through the side wall of the housing 3. A positioning component 1 for locking the angle of the convex lenses 2 is provided at the end of the shafts 5. In use, the rotational cooperation between the shafts 5 and the side wall of the housing 3 allows the tilt angle of the mounting plate 4 to be adjusted according to usage requirements. This allows the convex lenses 2 to be easily rotated and adjusted to different tilt angles, effectively improving the performance of the convex lenses 2. The positioning component 1 then locks the tilt angle of the convex lenses. 2. Positioning and locking improves the stability of the convex lens 2 after tilting, maintains the stability of the driver's field of vision, reduces driver distraction from frequent adjustments of the convex lens 2, and enhances driving safety. When one of the convex lenses 2 is damaged by external forces such as flying stones, the mounting plate 4 can be turned over and flipped to expose the convex lens 2 on the other side of the mounting plate 4 for use. This allows the two convex lenses 2 to be used interchangeably, enabling temporary replacement of the other convex lens 2 when it breaks. Users do not need to immediately replace the lens or the entire rearview mirror, which is especially suitable for emergency scenarios such as high-speed driving. It also reduces the overall waste caused by individual lens damage and saves costs.

[0026] Further as Figure 1 , Figure 4 and Figure 6As shown, it is worth noting that the positioning component 1 includes an end plate 103 fixed to the end of one of the shafts 5. Multiple evenly spaced protrusions 104 are fixed on the columnar side of the end plate 103. A protrusion 102 is fixed on the outer wall of the housing 3, and a metal spring 101 is fixed on the side of the protrusion 102. The end of the metal spring 101 engages with two adjacent protrusions 104 to lock the end plate 103. Through the rotational cooperation between the shaft 5 and the side wall of the housing 3, the tilt angle of the mounting plate 4 can be adjusted according to usage requirements, allowing the convex lens 2 to be easily rotated and adjusted to different tilt angles. The metal spring 101 engages with two adjacent protrusions 104, thereby using the metal spring 101 and the protrusions 104 to position and lock the convex lens 2 after tilt angle adjustment. This improves the stability of the convex lens 2 after tilt angle adjustment, maintains the stability of the driver's field of vision, reduces driver distraction from frequent adjustments of the convex lens 2, and enhances driving safety.

[0027] Further as Figure 5 and Figure 6 As shown, it is worth noting that a rotating head plate 6 is fixed to the end of another shaft 5. Multiple convex ribs 9 arranged in a ring are provided on the column side of the rotating head plate 6. In actual operation, the rotating head plate 6 can be used to easily rotate and adjust the convex mirror 2, which is convenient for operation.

[0028] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that the outer casing 3 has multiple drainage holes 7 on its side, and these drainage holes 7 are evenly distributed. In actual operation, the drainage holes 7 effectively improve the drainage efficiency of rainwater inside the outer casing 3 and effectively reduce the impact of rainwater.

[0029] This solution has the following working process: During use, the rotational engagement between the shaft 5 and the side wall of the housing 3 allows the tilt angle of the mounting plate 4 to be adjusted according to usage requirements. This enables the convex lens 2 to be easily rotated and adjusted to different tilt angles. The metal spring 101 engages with two adjacent convex teeth 104, thereby locking the convex lens 2 after tilt angle adjustment through the cooperation of the metal spring 101 and the convex teeth 104, improving the stability of the convex lens 2 after tilt angle adjustment. When one of the convex lenses 2 is damaged by external forces such as flying stones, the mounting plate 4 can be turned over and flipped, exposing the convex lens 2 on the other side of the mounting plate 4 for use. This allows the two convex lenses 2 to be used interchangeably, enabling temporary replacement of the other convex lens 2 when it breaks, without requiring the user to immediately replace the lens or the entire rearview mirror.

[0030] Further as Figure 2 and Figure 5 As shown, it is worth noting that 3M adhesive tape 8 is attached and fixed to the bottom surface of the outer casing 3, and a rubber sleeve is attached and fitted to the outer surface of the rotating head plate 6; the outer casing 3 can be glued and fixed to the rearview mirror surface for use by means of the 3M adhesive tape 8.

[0031] In summary: The rotational engagement between the shaft 5 and the side wall of the housing 3 allows for adjustment of the mounting plate 4's tilt angle according to usage requirements. This enables the convex lens 2 to be easily rotated and adjusted to different tilt angles, effectively improving its performance. The positioning component 1 locks the convex lens 2 in place after tilt adjustment, enhancing its stability and maintaining a stable driving view. This reduces driver distraction from frequent adjustments, improving driving safety. If one convex lens 2 is damaged by external forces such as flying stones, the mounting plate 4 can be flipped over, exposing the other side of the convex lens 2 for use. This allows for the replacement of one convex lens 2 with the other, eliminating the need for immediate replacement of the entire rearview mirror. This is particularly suitable for emergency scenarios such as high-speed driving, reducing waste caused by individual lens damage and saving costs.
