Description

Frameless rearview mirror

Technical Field

The utility model relates to the technical field of vehicles, in particular to a frameless rearview mirror.

Background

When driving at night, the light of the rear vehicle is reflected by the inner rearview mirror to cause night blindness of the driver, even if the glare light source is removed, the image remained in the eyes can also cause blind spots, and the phenomenon is called as 'white spot effect'. The "white spot effect" increases the reaction time of the driver, making it difficult to determine the potential hazard ahead of the road. Thus, an automatic anti-glare rear view mirror that can adapt to different incident light intensities is produced. The automatic anti-glare rearview mirror is characterized in that a layer of electrochromic material is additionally arranged in the mirror surface, and when the automatic anti-glare rearview mirror is irradiated by strong light, the material controlled by a photosensitive element can automatically deepen the color and change the reflectivity, so that the anti-glare effect is achieved.

With the development of the vehicle industry, rimless automatic anti-glare rearview mirrors are proposed, the front surfaces of which are completely exposed and the edges of which are not blocked. Compared with the rearview mirror with the frame, the frameless rearview mirror can provide a larger visual field, and is easier to clean because the edge of the lens is not covered by the frame.

In the existing frameless automatic anti-glare rearview mirror, a lens is directly attached to a mirror shell, smooth transition is formed between the edge of the lens and the outer surface of the mirror shell, the disassembly is difficult, the lens can directly bear force during the disassembly, and the damage is very easy to cause.

Detailed Description

The detailed features and advantages of the present invention are described in detail in the detailed description which follows, and will be sufficient for anyone skilled in the art to understand the technical content of the present invention and to implement the present invention, and the related objects and advantages of the present invention will be easily understood by those skilled in the art from the description, claims and drawings disclosed in the present specification.

Fig. 1 is a perspective view showing a frameless rear view mirror in the prior art, fig. 2 is a schematic structural view of the frameless rear view mirror shown in fig. 1, and fig. 3 is a partial schematic view of the frameless rear view mirror shown in fig. 1.

As shown in fig. 1 to 3, the rimless rear view mirror includes a mounting bracket 1, a lens assembly 2, a mirror housing 4, a connecting plate 41, wherein one end of the mounting bracket 1 is mounted to an inner surface of a front windshield of a vehicle, and the other end of the mounting bracket 1 is pivotably mounted to the mirror housing 4 such that the mirror housing 4 can be rotated relative to the mounting bracket 1, thereby adjusting an angle of the rear view mirror. The lens assembly 2 has a first surface 21 facing the driver and a second surface 22 opposite thereto, the second surface 22 being fixedly mounted to the connecting plate 41 by means of double-sided adhesive tape, the connecting plate 41 being fixed in the mirror housing 4 by means of a press-fit or snap-fit, so that the peripheral edge 23 of the lens assembly 2 is exposed and the first surface 21 is completely uncovered or covered. The peripheral edge 23 of the lens assembly 2 is substantially flush with the end peripheral surface of the mirror housing 4 to maximize the rearward view. However, since the periphery 23 of the lens assembly 2 is closely adjacent to the outer peripheral surface of the end of the lens housing 4, the lens assembly needs to be disassembled through a process groove between the two, and since the edge is the lens glass, the lens is directly stressed during the disassembly, and the lens is easily damaged.

In view of this, the present invention proposes a frameless rear-view mirror which is easy to disassemble. As shown in fig. 4, the rear view mirror assembly includes a mounting bracket 10, a lens assembly 20, a protective frame 30, and a mirror housing 40, wherein one end of the mounting bracket 10 is mounted to an inner surface of a front windshield of a vehicle, and the other end of the mounting bracket 10 is pivotally mounted to the mirror housing 40 such that the mirror housing 40 can be rotated with respect to the mounting bracket 10, thereby adjusting an angle of the rear view mirror. The lens assembly 20 is fixedly mounted in the protective frame 30, and the protective frame 30 is fixedly connected to the mirror housing 40.

As shown in fig. 5, the lens assembly 20 has a first surface 210 facing the driver, an opposite second surface 220, and a periphery 230 surrounding the first surface, and the protective frame 30 has a peripheral portion 310 and an attachment surface 320 surrounded by the peripheral portion 310. In the embodiment shown in fig. 5, the second surface 220 of the lens assembly 20 is attached to the attachment surface 320 of the protective frame 30 by double-sided adhesive so that the lens assembly 20 is fixed relative to the protective frame 30, alternatively, the lens assembly 20 may be fixedly mounted to the protective frame 30 by other suitable means.

As shown in fig. 6, the front end of the protective frame peripheral portion 310 abuts the lens assembly such that the peripheral edge 230 of the lens assembly is exposed and the first surface 210 of the lens assembly is completely unobstructed or covered. The rear end of the protection frame peripheral portion 310 is connected to the mirror housing 40, and in the embodiment shown in fig. 6, the protection frame 30 may alternatively be fixedly connected to the mirror housing 40 by providing a plurality of snaps 410 at the front end of the mirror housing 40 for fixedly connecting to the protection frame peripheral portion 310, or by other suitable means, such as press-fitting to the mirror housing 40.

The peripheral edge 230 of the lens assembly, the peripheral surface of the protective frame peripheral portion 310, and the peripheral surface of the mirror casing 40 are substantially flush, providing a substantially smooth transition from the lens assembly 20 to the protective frame 30 to the mirror casing 40. By providing the protective frame 30 between the lens assembly 20 and the mirror housing 40, the detachment work can be performed in the process groove formed between the protective frame outer peripheral portion 310 and the mirror housing 40, and the lens is not affected during detachment, thereby preventing damage to the lens.

In a preferred embodiment, the lens assembly 20 is an electrochromic lens, and includes a first lens layer, an electrochromic layer, a conductive layer, a sealing member, and a second lens layer, wherein the electrochromic layer is sandwiched between the first lens layer and the second lens layer, and the conductive layer is disposed between the first lens layer and the electrochromic layer and/or between the second lens layer and the electrochromic layer; the sealing member encloses the electrochromic layer and is disposed between the first lens layer and the second lens layer.

The surface of the first lens layer and/or the second lens layer, which is contacted with the electrochromic layer, is a conductive mirror surface, and the conductive mirror surface is connected with the conductive layer. The conductive layer transmits a voltage signal of the control circuit to the two conductive mirror surfaces, so that the coloring and the fading of the electrochromic layer are controlled through the voltage regulation of the electrochromic layer.

The electrochromic layer enables the frameless rearview mirror to have an anti-dazzle effect, and the principle is that the electrochromic layer can adjust the intensity of reflected light according to the intensity of external light through an electronic induction system, so that the anti-dazzle effect is achieved, and driving is safer. In the normal state, the cathode of the electrolyte solution in the electrochromic layer is in a colorless oxidized state, and the anode is in a yellowish normal state. When the electrochromic layer is biased with a dc voltage, the cathode changes from a colorless state to blue, and the anode changes from a colorless state to yellow. When the two colors of blue and yellow are mixed, the dark green color is obtained visually. Due to the change of the color of the electrochromic layer, the light absorption effect of the electrochromic layer greatly reduces the light rays which should be reflected by the reflecting layer originally, thereby realizing the anti-dazzling function of the rearview mirror.

The conductive layer is made of a material with low resistance, is connected with the power supply unit, and is used for providing an electric field for the electrochromic layer, so that the optical properties (reflectivity, transmittance, absorptivity and the like) of the electrochromic layer generate a stable and reversible color change phenomenon under the action of the electric field, and the color and the transparency are reversibly changed in appearance.

The sealing member sets up and is used for sealing up electrochromic layer in the electrochromic layer outside, because electrochromic layer is mostly liquid or colloidal substance, in order to prevent its loss, sets up the sealing member in the electrochromic layer outside to guarantee that electrochromic layer can not flow out, the life of extension electrochromic layer.
