Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted display, in particular to an integrated structure of a vehicle-mounted central control display screen and a domain controller. Background Art

[0002] Traditional car computers and central control display systems are separately connected through various wiring harnesses, and the display screen, domain controller, and wiring harness suppliers are basically fixed to different suppliers. Under this solution, the three parts will cause some compatibility problems, and there are also certain electromagnetic compatibility issues, which will affect the display effect of the central control display screen.

[0003] There are also solutions in the existing market that combine the central control display screen and the domain controller as an all-in-one device. However, the switch board and the main board are separated and connected through a board-to-board connector or a cable. There are problems such as unreliable connection, signal loss, and electromagnetic interference. At the same time, this structure has a large space requirement for the dashboard, and the domain controller needs to be placed inside the dashboard. With the trend of increasingly simple and flat interiors of existing cars, the space available inside the dashboard is getting smaller and smaller. This all-in-one solution can no longer meet the requirements of rapidly developing cars.

[0004] To this end, we proposed an all-in-one structural design of the vehicle-mounted central control display screen domain controller. Utility Model Content

[0005] The purpose of the utility model is to provide a vehicle-mounted central control display screen domain controller integrated machine structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated structure of a vehicle-mounted central control display screen domain controller, including a glass cover plate, a touch button membrane, an optical film, a display screen, a backlight source assembly, structural adhesive, a front panel, a printed circuit board, a heating element, a thermal conductive gel, an extruded aluminum radiator, screws, an external connector and a rear shell. The touch button membrane is attached to the touch button at the bottom of the glass cover plate by optical adhesive, and the glass cover plate is optically bonded to the display screen by optical film to form a display module.

[0007] Furthermore, an explosion-proof optical film is affixed to the surface of the glass cover.

[0008] Furthermore, the display module composed of the glass cover plate, the touch button membrane, the optical film, the display screen and the backlight source assembly is bonded to the front panel by means of structural adhesive.

[0009] Furthermore, the thermally conductive gel is dispensed on the top surface of the heating element by automated equipment.

[0010] Furthermore, the external connector is soldered on a printed circuit board by a through-hole reflow process, and the printed circuit board integrates both display and touch functions.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. This patent integrates the switch board and the main board into a printed circuit board, which is placed parallel to the display screen, reducing the reliance on dashboard space. At the same time, the integrated structural design eliminates the board-to-board connector, reduces costs, and avoids electromagnetic interference problems. It can also be extended to other OEMs and vehicle models, and has a certain degree of versatility.

[0013] 2. The patented integrated structural design of the vehicle-mounted central control display screen and domain controller combines the traditional structural design that separates the display screen and the domain controller, achieving low cost and lightweight requirements while ensuring functionality, reducing space limitations on the vehicle dashboard and improving product competitiveness in the market.
