Abstract
The invention relates to the technical field of automotive accessories, in particular to a manufacturing technology of a backlight lamp control assembly of an automotive instrument panel. The manufacturing technology comprises the following steps that a digital adjustable resistor, a power source, a processor and a light sensor are all prepared based on the prior art; a packaging tank is of a square box shape, is provided with a top face to be packaged and is made from a copper plate easy to cool on the whole; and the outer wall of the packaging tank is sprayed with pretreatment liquid, and direct drying is carried out after spraying is finished; and the digital adjustable resistor, the power source, the processor and the light sensor are connected through the electric principle structure, the assembly is placed into the packaging tank, and finally the top face is sealed. Since the outer wall of the packaging tank is pretreated, a hydrophobic layer is formed on the outer wall of the packaging tank, condensation is not likely to be produced, and the outer wall is prevented from being corroded.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a manufacturing process of a backlight control assembly of an automobile instrument panel. Background technique [0002] With the progress of science and technology, automobiles have also been popularized in my country. Automobile dashboards are a common auto accessory. The brightness of the backlights in existing automobile dashboards cannot be adjusted, and the user experience is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automobile instrument panel, which can adjust the brightness of the backlight according to the ambient brightness and improve user experience. At the same time, the invention also provides a backlight control assembly of an automobile instrument panel and a manufacturing process thereof. [0004] In order to solve the above-mentioned technical problems, the technical solution adop...
