Description

[0002] In the existing automobile main machine, an onboard antenna is often used, and an antenna unit is formed on a main machine circuit board, that is, a main circuit mounting area of the main machine and an antenna mounting area of the antenna are formed on the circuit board. However, based on the main circuit of the main machine, the main circuit of the main machine often needs to be designed with a shielding shell with a shielding function, so it is necessary to separately design an antenna cover for protecting the onboard antenna. The antenna mounting area of the circuit board extends from an opening in the side of the shell to outside the shielding shell, and the antenna cover is covered on the antenna mounting area and fixed together through a plastic buckle and a screw. Not only is the buckle alignment and screw installation required, but the edge of the shielding shell often needs to be filled with conductive glue for EMC shielding. Therefore, a certain gap is formed between the edge of the shielding shell forming the opening and the main board, so that when the screw is installed, due to the gap precision and matching degree, the antenna cover is raised, causing the screw locking hole to be misaligned, and a clamp needs to be used for re-pressing, further increasing the difficulty of assembly and automated operation.

[0003] Therefore, in the Chinese patent CN215989244U, an onboard antenna cover and a main machine structure with an onboard antenna are disclosed. Elastic arms that can deform in the up-down direction are formed on the upper and lower sidewalls of the onboard antenna cover. During assembly, the upper and lower shells of the main machine press and fit the elastic arms on the upper and lower sides of the antenna cover to fix the antenna cover on the main machine shell.

The engaging hooks comprise clamping arms and second guide protrusions formed at the ends of the clamping arms. The second guide protrusions of the two opposite engaging hooks are oppositely arranged. The second guide protrusions are provided with guide walls for guiding the first guide protrusions to extend in. The second guide protrusions are spaced apart from the third side wall and form clamping grooves for engaging with the first guide protrusions between the second guide protrusions and the third side wall.

5. The on-board antenna cover mounting structure of claim 1, wherein: The elastic clamping arms are spaced apart from the upper side edges of the entrance of the receiving cavity. The left and right side edges of the entrance of the receiving cavity are further provided with bearing side walls connected with the lower side edges of the entrance of the receiving cavity. The bearing side walls are spaced apart from the elastic clamping arms to form clamping areas. When the antenna cover is engaged with the main shell, the edges of the substrate of the on-board antenna are engaged with the clamping areas.

6. The on-board antenna cover mounting structure of claim 1, wherein: When the antenna cover is engaged with the main shell, the upper and lower side edges of the entrance of the antenna cover abut with the third side wall.

7. The on-board antenna cover mounting structure of claim 1, wherein: The main housing comprises a first housing and a second housing which are matched with each other, the first housing comprises a top shell and a side wall, the side wall comprises a first side wall, a second side wall and an upper half of a third side wall, the second housing comprises a bottom shell and a lower half of the third side wall, the first housing and the second housing are oppositely installed to form an installation cavity for installing a circuit board between the first housing and the second housing, the upper half and the lower half of the third side wall are matched to form a gap for the substrate of the on-board antenna to pass through, and the circuit board comprises a main circuit board and a substrate of an on-board antenna.

8. The on-board antenna cover mounting structure of claim 7, wherein: A first contact block is protruded on the upper half and contacts with an upper side of the entrance of the antenna cover, a second contact block is protruded on the lower half and contacts with a lower side of the entrance of the antenna cover, and the upper side and the lower side of the entrance of the antenna cover respectively contact with the first contact block and the second contact block when the antenna cover is snap-fitted on the main housing.

9. The on-board antenna cover mounting structure of claim 1, wherein: The first side wall and the second side wall are at an angle to make the on-board antenna formed at a corner of the main housing. 10.A host of an intelligent cabin, characterized in that: The main housing, the circuit board and the antenna cover are provided, the circuit board comprises a main circuit substrate and a substrate of an on-board antenna which is extended outward from the main circuit substrate, the main housing is formed with a receiving cavity for installing the main circuit substrate and makes the substrate of the on-board antenna exposed outward, and the antenna cover is snap-fitted on the main housing and forms the on-board antenna cover installation structure as claimed in any one of claims 1-9 to cover the substrate of the on-board antenna.
