Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example (b):
the embodiment provides a WIFI structure of on-vehicle double screen all-in-one, as shown in fig. 1, the double screen all-in-one is including laminating subassembly 10, plastic panel 20, two LCM switching PCB boards 30, two host computer PCB boards 40 and the back shroud subassembly 50 of laminating two screens entirely, independently assembles WIFI antenna 60 on the plastic panel 20, between two screens of double screen all-in-one, closely paste the PCB board of WIFI antenna 60 the cover plate glass of subassembly 10 that laminates entirely can avoid receiving the influence of screen and back shroud subassembly.
As shown in fig. 2, the PCB board 61 of the WIFI antenna 60 may be connected to the socket of the host PCB board 40 through a cable with a plug. And a misplacement notch is arranged on the PCB 61 of the WIFI antenna 60.
As shown in fig. 3 and 4, the plastic panel 20 is provided with a card slot 21 for fixing the WIFI antenna PCB 61, a support plate 22 with an elastic wall, and an elastic clip 23. The WIFI antenna PCB 61 is assembled in the card slot 21 of the plastic panel 20, and the PCB 61 of the WIFI antenna is pressed against by the elastic buckle 23. The elastic wall comprises two U-shaped grooves, the U-shaped groove both ends support the PCB board 61 of WIFI antenna, exert pressure all the time on PCB board 61, prevent PCB board 61's not hard up. The PCB 61 of the WIFI antenna is limited by the degrees of freedom of the plastic panel 20 in multiple directions, so that the reliability of the PCB 61 of the WIFI antenna after assembly is ensured.
