Problems solved by technology

[0004] 1. The gear position characters may appear blurred due to light problems, making it time-consuming for the driver to search for a gear, leaving the eyes of the road for a long time, posing hidden dangers to driving safety;
[0005] 2. The accuracy of file search is low. The gear panel is made of traffic white PC material injection molding due to the light transmission requirements of the gear characters. After the engraving is completed, traffic white is displayed when the backlight is off, and low-brightness white is displayed when the backlight is on.
When the driver is looking for a gear, the recognition will be blurred, or even misplaced, and there is a hidden danger of entering the wrong gear;
[0006] 3. The appearance is monotonous, which affects the beauty of the car interior

Embodiment 1

[0045] Such as Figure 4 , Figure 5 and Image 6 The shown dark-surface light-transmitting automotive electronic gearshift indicator panel includes a fixed block 4, a transparent panel arranged on the top of the fixed block 4, a black paint layer arranged between the transparent panel 1 and the fixed block 4, A light-emitting LED circuit board 5 arranged at the bottom of the fixed block 4 and a plurality of light guide blocks 3 embedded in the fixed block 4, the black paint layer includes a plurality of character black paints 6 arranged between the transparent panel 1 and the fixed block 4 And the high-gloss black paint 2 located around the character black paint 6, a plurality of LED lights 7 are arranged on the light-emitting LED circuit board 5, and the light emitted by the LED lights 7 passes through the corresponding light guide block 3 to illuminate the character black paint 6.

[0046] The character black paint 6 and the high-gloss black paint 2 are located on the bottom s...

Embodiment 2

[0063] The material of the transparent panel 1 in this embodiment is transparent polycarbonate;

[0064] The character black paint coating composition includes the following components and parts by weight content: 10 parts of character paint main agent, 0.9 part of character paint curing agent and 1 part of character paint thinner;

[0065] The high-gloss black paint coating composition includes the following components and contents by weight: 5 parts of high-gloss paint main agent, 1 part of high-gloss paint curing agent and 4 parts of high-gloss paint diluent;

[0066] When the gear character of the value gear is in the high-bright state, the other gear characters are in the low-bright state, so that the driver can perform gear shift operations;

[0067] The rest is the same as in Example 1.

Embodiment 3

[0069] The material of the transparent panel 1 in this embodiment is polymethyl methacrylate;

Abstract

The invention relates to a dark-surface light-transmitting automobile electronic gear position indication panel and a manufacturing method thereof. The gear position indication panel comprises a fixedblock, a transparent panel arranged at the top of the fixed block, a black paint layer arranged between the transparent panel and the fixed block, a light-emitting LED circuit board arranged at the bottom of the fixed block and a light guide block embedded in the fixed block; and the black paint layer comprises a plurality of characters of black paint and highlight black paint located on the peripheries of the characters of black paint. The manufacturing method comprises the following steps: 1) preparing the transparent panel; 2) spraying the highlight black paint at the bottom of the transparent panel; 3) engraving a gear position character area on the highlight black paint; 4) printing the characters of black paint in the gear position character area; and 5) assembling the transparent panel, the fixed block, the light-emitting LED circuit board and the light guide block together to obtain the gear position indication panel. Compared with the prior art, the gear position indication panel in the invention has the advantages that the structure is simple, the manufacturing method is convenient and fast, the problem that gear position characters are not clearly displayed can be effectively solved, and a good application prospect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of automobile parts, and relates to a dark-surface light-transmitting automobile electronic gear position indicator panel and a manufacturing method thereof. Background technique [0002] When driving a car, the visibility of the gear position has a direct relationship with the driver's rapid identification of the gear position and the speedy upshift and downshift operations. Such as figure 1 , figure 2 and image 3 Shown is an existing gear indicating panel with LED backlight engraving gear characters. The semi-transmissive panel 8 on the top of the indicating panel is made of translucent material such as white polycarbonate (PC). The bottom surface of the panel 8 is sprayed with high-gloss black paint 2 to engrave the gear characters. In order to ensure the uniformity of light transmission, a light guide block 3 is provided under the indicator panel, and the light guide block 3 is embedded in the groove of th...
