Electronic unit for a vehicle and manufacturing method

A method for manufacturing an electronic unit with two or more surface elements arranged next to one another and with a visible surface, for a vehicle, comprising the steps:

• provisioning two or more surface elements arranged next to one another on a first device and with a visible surface side and an opposite surface underside, wherein the surface elements are each fixed in a housing, and wherein the housing has a housing top side facing the surface underside and an opposite housing underside, and wherein each housing on its housing underside has at least one protruding fixing element for fixing the surface elements to a carrier plate which connects the two or more surface elements together;
• having releasable connection of the fixing elements to a respective index element by force fit and/or form fit;
• adjusting of the surface elements in a first position relative to one another and to the first device, so that the surface elements are arranged level with one another, and freezing of the position of the surface elements in the first adjusted position on the first device;
• adjusting of the carrier plate relative to the housings with the surface elements by orientation points on the surface elements and/or the housings, and also adjustment of the carrier plate relative to the index elements by a second device so that at least one air gap is present between the carrier plate and the respective index elements;
• and having substance-bonded connection of the index elements to the carrier plate so that the air gap is at least partially closed by means of the substance-bonded connection, so that each surface element is separately releasably fixed to the carrier plate, and wherein by the index elements, the surface elements can be adjusted relative to and level with one another and
• securing the index element to the fixing element by a screw accessible via a recess through the carrier plate in which the index element is at least partially arranged;
• bonding the index elements and the carrier plate together by an adhesive as a substance-bonded connection,
• wherein the index elements have cutouts pointing away from a recess edge configured as circumferential channels that receive the adhesive for a mechanical fixing of the carrier plate to the index elements.
