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] The present embodiment provides an automobile rearview mirror and a method for preparing the rearview mirror, comprising the following steps: adopting a thermal expansion coefficient of 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 car rearview mirror. The mold is cleaned with acetone dipped in non-woven fabric. After cleaning, let it dry naturally. Let it air for 10 minutes and then wipe it evenly with a non-woven fabric dipped in mold release wax. After airing for 10 minutes, take another clean non-woven fabric to wipe the surface of the mold to remove excess mold release wax, and then follow [0 / 45 / -45 / 90 / C 0.6 ] s Lay 3K unidirectional carbon cloth and reinforcing felt with a thickness of 0.6mm. After laying, lay down demoulding 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. HR-196 resin...

Embodiment 2

[0043] The present embodiment provides an automobile rearview mirror and a method for preparing the rearview mirror, comprising the following steps: adopting a thermal expansion coefficient of 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 car rearview mirror. The mold is cleaned with acetone dipped in non-woven fabric. After cleaning, let it dry naturally. Let it air for 10 minutes and then wipe it evenly with a non-woven fabric dipped in mold release wax. After airing for 10 minutes, take another clean non-woven fabric to wipe the surface of the mold to remove excess mold 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 the laying is completed, lay down the demoulding cloth, diversion net and diversion pipe in sequence according to the vacuum bag pressing process. Seal and connect the vacuum pump with a ...

Embodiment 3

[0045] The present embodiment provides an automobile rearview mirror and a method for preparing the rearview mirror, comprising the following steps: adopting a thermal expansion coefficient of 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 car rearview mirror. The mold is cleaned with acetone dipped in non-woven fabric. After cleaning, let it dry naturally. Let it air dry for 10 minutes and wipe it evenly with a non-woven fabric dipped in mold release agent, then follow [0 / 45 / -45 / 90 / C 2 ] s A 12K unidirectional carbon cloth and a reinforcing felt with a thickness of 2 mm were placed in the mold in turn. After the placement, HR-8300 resin was introduced at 0.15 MPa according to the RTM process, and cured at 130 °C for 2 hours. After curing, demould, take out the carbon fiber sandwich composite board, cut off the leftovers by water cutting, and then use 600 and 800 grit water sandpaper to polish one sid...

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...
