This utility model discloses a carbon fiber antenna reflector surface processing device, relating to the field of antenna manufacturing technology. It aims to solve the technical problem that the special design of shark fin antenna reflectors often leads to incomplete polishing and damage to the antenna surface during polishing. The polishing device includes a mounting base, inside which a drive motor is fixedly installed. A rotating rod is fixedly installed at the output end of the drive motor. This utility model, through the spring seat in the mounting groove of the base, provides the polishing block with a telescopic function. When the polishing block contacts the shark fin edge reflector surface, it can automatically conform to the reflector surface at different positions. This utility model has the advantages of flexibly adjusting the contact position with the reflector surface, expanding the polishing range, and improving the polishing effect.

This invention discloses a vehicle-mounted dual-frequency satellite navigation glass antenna, which is a sunroof glass antenna device for vehicle use. It can be installed in conjunction with the sunroof of the vehicle, avoiding the increased design difficulty caused by installation inside the shark fin and the greater influence of surrounding electrical appliances caused by installation in front of the dashboard, thus limiting the antenna performance. It includes a glass substrate, a signal layer, a ground plane (1) and a dielectric substrate (7). The signal layer and the dielectric substrate (7) are sandwiched in the glass substrate, and the ground plane (1) is located on the surface of the glass substrate. The signal layer includes a microstrip network (2) and an input microstrip line (10) coupled thereto.

This utility model provides a shark fin shell protective structure and a vehicle. The shark fin shell protective structure includes a shell body, a clamping component, and a connecting component. A connecting groove is provided on the first end face of the shell body facing the clamping component, the connecting groove being recessed from the first end face away from the clamping component. A snap-fit ​​protrusion is provided on the second end face of the clamping component facing the shell body, the snap-fit ​​protrusion being protruded from the second end face towards the shell body and engaging with the connecting groove. Both the shell body and the clamping component have connecting portions. This shark fin shell protective structure can achieve IP69K protection level. By replacing the 3M adhesive in the original technology, it solves the technical defects caused by 3M adhesive bonding, enables pre-positioning during assembly and meets protection level requirements, improves product assemblability, has a simple overall structure, is easy to assemble, solves the problem of pre-positioning during installation, and reduces cost.
