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 Figure 6 A car electronic gear position indicator panel with a dark surface and light transmission shown, including a fixed block 4, a transparent panel 1 arranged on the top of the fixed block 4, a black paint layer arranged between the transparent panel 1 and the fixed block 4, The 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 paint 6 arranged between the transparent panel 1 and the fixed block 4 As well as the high-gloss black paint 2 around the character black paint 6, a plurality of LED lamps 7 are arranged on the light-emitting LED circuit board 5, and the light emitted by the LED lamps 7 passes through the corresponding light guide block 3 and irradiates on the character black paint 6.

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

Embodiment 2

[0063] In this embodiment, the material of the transparent panel 1 is transparent polycarbonate;

[0064] The character black paint composition comprises the following components and contents in parts by weight: 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 composition comprises the following components and contents in parts 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 thinner;

[0066] When the gear character of the current gear is in a bright state, the rest of the gear characters are in a low light state, so that the driver can perform gear shifting operations;

[0067] All the other are with embodiment 1.

Embodiment 3

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

Abstract

The invention relates to an automotive electronic gear position indicator panel with dark surface and light transmission and its manufacturing method. The paint layer, the light-emitting LED circuit board arranged at the bottom of the fixed block and the light guide block embedded in the fixed block, the black paint layer includes a plurality of character black paint and high-gloss black paint around the character black paint; the production method includes: 1. ) Prepare a transparent panel; 2) Spray high-gloss black paint on the bottom of the transparent panel; 3) Carve out a gear character area on the high-gloss black paint; 4) Print character black paint on the gear character area; 5) Put the transparent panel, the fixed block , light-emitting LED circuit board and light guide block are assembled together to obtain the gear indicating panel. Compared with the prior art, the present invention has simple structure and convenient manufacturing method, can effectively solve the problem of unclear display of gear characters, and has better application prospects.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to an automotive electronic gear position indicating panel with a dark surface and a light-transmitting panel and a manufacturing method thereof. Background technique [0002] When driving a car, the visibility of the gear position is directly related to the driver's quick recognition of the gear position, and the operation of upshifting and downshifting as soon as possible. Such as figure 1 , figure 2 and image 3 Shown is a gear indicating panel of an existing LED backlight engraved gear character, the semi-transparent panel 8 on the top of the indicator panel is formed by injection molding of a semi-transparent material such as white polycarbonate (PC). The bottom surface of the panel 8 is sprayed with high-gloss black paint 2, and the gear characters are engraved. In order to ensure the uniformity of light transmission, a light guide block 3 is provided under the indicator...
