Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an anti-glare rearview mirror structure for automobiles with notched electrode plates. Background Technology

[0002] Rearview mirrors are key visual tools in automobiles used to assist drivers in observing the rear, sides, and surrounding environment of the vehicle. They help drivers understand the traffic conditions around the vehicle, reduce blind spots, and thus perform maneuvers such as turning, changing lanes, reversing, and parking more safely. They are an important component for ensuring driving safety. Cars are usually equipped with multiple rearview mirrors. Common ones include the interior rearview mirror mounted above the windshield inside the vehicle, and the exterior rearview mirrors mounted on the left and right doors or fenders of the vehicle body, respectively. The rearview mirrors in different positions are used in combination to create a comprehensive field of vision for the driver to observe the surrounding environment of the vehicle.

[0003] In existing anti-glare rearview mirrors, stress concentration can occur at the interface between the conductive substrate, electrode sheet, and conductive paste due to the difference in thermal expansion coefficients when subjected to rapid changes in high and low temperatures. This can lead to cracking, detachment, or glass breakage at the connection points, affecting the conductivity and stability of the anti-glare function. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a car anti-glare rearview mirror structure with notched electrode plates.

[0005] This utility model is achieved using the following technical solution: a car anti-glare rearview mirror structure with a notched electrode sheet, comprising a first substrate, a first substrate conductive layer fixedly connected to the top of the first substrate, an electrochromic layer fixedly connected to the top of the first substrate conductive layer, a sealant fixedly connected to the outer wall of the electrochromic layer, a conductive paste fixedly connected to the outer wall of the sealant, a second substrate conductive layer fixedly connected to the outer wall of the conductive paste, laser etching lines formed around the top periphery of the second substrate conductive layer, a second substrate fixedly connected to the top of the second substrate conductive layer, and a first notched electrode sheet disposed on the top of the second substrate. A second notched electrode sheet is disposed on one side away from the first notched electrode sheet. An insulating layer is fixedly connected to the outer wall of the sealant on the side away from the first notched electrode sheet. The conductive paste is fixedly connected to the outer wall of the first substrate conductive layer on the side close to the first notched electrode sheet. The conductive paste is fixedly connected to the outer wall of the second substrate conductive layer on the side close to the first notched electrode sheet. The conductive paste is fixedly connected to the outer wall of the second substrate conductive layer on the side close to the second notched electrode sheet. The conductive paste is fixedly connected to the top of the insulating layer on the side close to the insulating layer. The conductive paste is fixedly connected to the outer wall of the second notched electrode sheet on the side close to the insulating layer.

[0006] In the above technical solution, the first substrate and the second substrate are respectively composed of a first substrate conductive layer and a second substrate conductive layer, with an electrochromic layer located between them. The electrochromic layer is sealed around its perimeter with sealant. The first notched electrode sheet is electrically connected to the first substrate conductive layer via a conductive paste. The conductive paste covers both sides of the first notched electrode sheet and connects it to both the first and second substrate conductive layers. Laser etching lines are formed on the second substrate conductive layer, severing the electrical connection between the first notched electrode sheet and the second substrate conductive layer. The second notched electrode sheet is then electrically connected to the second substrate conductive layer via a conductive paste. The conductive paste covers both sides of the second notched electrode sheet, and at corresponding positions… An insulating layer is fixed on the first conductive base layer to ensure that the second notched electrode is electrically disconnected from the first conductive base layer. The notch shape of the first and second notched electrode sheets can be V-shaped, U-shaped, rectangular, arc-shaped, circular, or semi-circular. The notch penetrates the thickness of the electrode sheet, and the longest span of the shape is 0.1-5mm. The notches are symmetrically distributed along the length of the electrode sheet, or asymmetrically designed according to stress distribution requirements. When there are multiple notches, the shape and size do not need to be uniform. The first and second notched electrode sheets disperse stress through the notches to avoid stress concentration. The notch area allows conductive paste to fill and form mechanical anchoring, enhancing the bonding force, preventing cracking and damage at the connection, and ensuring the stability of the anti-glare function.

[0007] As a further improvement to the above scheme, the electrochromic layer is fixedly connected to the bottom of the second substrate conductive layer.

[0008] As a further improvement to the above solution, the sealant is fixedly attached to the top of the first substrate conductive layer.

[0009] As a further improvement to the above solution, the conductive paste is fixedly connected to the outer wall of the second substrate, and the conductive paste is fixedly connected to the outer wall of the conductive layer of the second substrate.

[0010] As a further improvement to the above solution, the first notched electrode sheet is fixedly connected inside the conductive paste.

[0011] As a further improvement to the above solution, the second notched electrode sheet is fixedly connected inside the conductive paste.

[0012] As a further improvement to the above solution, the insulating layer is fixedly connected to the bottom of the conductive paste near the side of the second notched electrode sheet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention comprises a first substrate and a second substrate, each composed of a first substrate conductive layer and a second substrate conductive layer, with an electrochromic layer positioned between them and sealed with sealant. A first notched electrode is electrically connected to the first substrate conductive layer via a conductive paste, ensuring the connection between the first notched electrode and the first and second substrate conductive layers. A laser etching line disconnects the electrical connection between the first notched electrode and the second substrate conductive layer. The second notched electrode is then electrically connected to the second substrate conductive layer via the conductive paste. An insulating layer disconnects the second notched electrode from the first substrate conductive layer. The notch disperses stress, preventing stress concentration. The notch area allows the conductive paste to fill and form a mechanical anchor to enhance the bonding force, ensuring the stability of the anti-glare function. Attached Figure Description
