Problems solved by technology

Although the weight of the optical glass rearview mirror lens itself is not very heavy, due to the relatively strong vibration of the rearview mirror assembly during the driving of the car, this requires the rearview mirror lens support structure to have sufficient strength and rigidity design, indirectly Increased weight of rearview mirror assembly
The existing patent CN201220281059.9 proposes to use low-density optical plastic lenses to make rearview mirror lenses with a lightweight effect, but the plastic rearview mirrors are not resistant to sand and gravel impacts, and the mirror surface is prone to scratches after being impacted during driving. image blur

Embodiment 1

[0041] This embodiment provides a kind of automobile rearview mirror and the preparation method of rearview mirror, comprise the following steps: adopt thermal expansion coefficient to be 5 * 10 -6 ppm·℃ -1 The glass is used as the mold material, and the mold is made according to the curvature and size of the rearview mirror of the car. The mold is cleaned with acetone with a non-woven cloth, and it is left to dry naturally after cleaning. Let it dry for 10 minutes and then wipe it evenly with a non-woven cloth dipped in release wax. After 10 minutes in the air, take another clean non-woven cloth to wipe the surface of the mold to remove excess release wax, and then follow [0 / 45 / -45 / 90 / C 0.6 ] s Lay 3K unidirectional carbon cloth and reinforced felt with a thickness of 0.6mm. After laying, lay the release cloth, diversion net and diversion pipe in sequence according to the vacuum bag pressing process, seal with a vacuum bag and connect the vacuum pump. Introduce HR-196 res...

Embodiment 2

[0043] This embodiment provides a kind of automobile rearview mirror and the preparation method of rearview mirror, comprise the following steps: adopt thermal expansion coefficient to be 5 * 10 -6 ppm·℃ -1 The glass is used as the mold material, and the mold is made according to the curvature and size of the rearview mirror of the car. The mold is cleaned with acetone with a non-woven cloth, and it is left to dry naturally after cleaning. Let it dry for 10 minutes and then wipe it evenly with a non-woven cloth dipped in release wax. After 10 minutes in the air, take another clean non-woven cloth to wipe the surface of the mold to remove excess release wax, and then follow [0 / 45 / -45 / 90 / C 2 ] s Lay 12K unidirectional carbon cloth and aramid honeycomb panels with a thickness of 2mm. After laying, lay the release cloth, diversion net and diversion pipe in sequence according to the vacuum bag pressing process, seal with a vacuum bag and connect the vacuum pump. Introduce HR-19...

Embodiment 3

[0045] This embodiment provides a kind of automobile rearview mirror and the preparation method of rearview mirror, comprise the following steps: adopt thermal expansion coefficient to be 6 * 10 -6 ppm·℃ -1 The metal is used as the mold material, and the mold is made according to the curvature and size of the rearview mirror of the car. The mold is cleaned with acetone dipped in non-woven cloth. Let it dry naturally for 10 minutes and then wipe it evenly with a non-woven cloth dipped in the release agent, and then follow [0 / 45 / -45 / 90 / C 2 ] s Lay 12K unidirectional carbon cloth and reinforced felt with a thickness of 2mm in the mold in sequence. After laying, introduce HR-8300 resin at 0.15MPa according to the RTM process, and cure at 130°C for 2 hours. After curing, remove the mold, take out the carbon fiber sandwich composite material board, use water cutting to cut off the leftover material, and then use 600 and 800 mesh water sandpaper to polish one side of the carbon fib...

Abstract

The invention provides an automobile rearview mirror and a manufacturing method thereof. The automobile rearview mirror consists of a carbon fiber composite material plate with a sandwich structure, and an ultrathin optical glass lens. Under the condition of equal thickness, the rearview lens structure with the innovative design has a lightening effect, and the system load also can be lowered greatly. Meanwhile, the adopted sandwich structure has a certain energy-absorbing effect, so that the composite rearview mirror structure is prevented from being broken easily compared with the conventional rearview mirror. Moreover, the ultrathin optical glass lens is used, so that resistance to gravel impact is realized, and the imaging definition is also ensured effectively. By adopting the novel automobile rearview mirror structure provided by the invention, the defects of various conventional rearview mirrors are overcome, and the performance of light weight and high definition is truly realized. The automobile rearview mirror can be widely applied to various vehicles.

Description

technical field [0001] The invention relates to the technical field of automobile rearview mirrors, in particular to an automobile rearview mirror with lightweight structure design and a manufacturing method thereof. Background technique [0002] The car rearview mirror is used to reflect the rear, side and bottom of the car, so that the driver can indirectly see the situation at these positions, expand the driver's field of vision, and play the role of "second eye". There are three kinds of materials used for rearview mirror lenses: ordinary optical glass, special optical glass and optical plastic lens. At present, commercial vehicles often use ordinary optical glass. Although the weight of the optical glass rearview mirror lens itself is not very heavy, due to the relatively strong vibration of the rearview mirror assembly during the driving of the car, this requires the rearview mirror lens support structure to have sufficient strength and rigidity design, indirectly Inc...
