Abstract

The utility model relates to an automobile carried aerial box with a magnetic base, which is composed of a box cover 1, a base 2 and an antenna basal plate 8. The upper side of the bottom of the base 2 is provided with a groove 6 containing a permanent magnet 3 and four support frames 5. The lateral part is provided with a lead bushing 7. The permanent magnet 3 is contained in the groove 6. The lower side of the box cover 1 is provided with four shores 4 which are opposite to the support frames 5 on the base 2. The shores 4 on the box cover and the support frames on the base are used for holding the antenna basal plate. The box cover 1 and the base 2 are sleeved together. The utility model has the advantages of easy manufacture, low cost, simple disassembly and assembly, and convenient maintenance. Due to the adoption of the base with the permanent magnet, the antenna can be conveniently positioned on an automobile or the mounting position of the antenna can be changed conveniently.

Description

Automobile carry aerial box with magnetic base

The utility model relates to a kind of vehicle GPS (global positioning system) antenna.

The box body of gps antenna both domestic and external is big, cost is high, and its base is all fixed with screw thread and car body, is difficult for installation and removal, needs repairing or very inconvenient when changing the installation site of antenna box.

Because above-mentioned, the purpose of this utility model be a kind of easy installation of design, quick detachable, be convenient to keep in repair the car antenna of antenna and portable antenna installation site.

The purpose of this utility model is achieved in that the magnetic bases car antenna is made up of lid, base and antenna substrate; The downside of said lid has fore-set; The bottom upside of said base has support column and holds the groove of permanent magnet, and the leaded conduit of its sidepiece, said permanent magnet are contained in the groove on the said base; Fore-set on the said lid and the support column on the base are in order to the clamping antenna substrate, and said lid and base sheath lump together.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of base.

Magnetic bases car antenna shown in the figure is made up of injection moulding lid 1, injection moulding base 2 and antenna substrate 8, the bottom upside of base 2 has groove 6 and four support columns 5 that hold Nd-Fe-B permanent magnet 3, its sidepiece has antenna lead conduit 7, and Nd-Fe-B permanent magnet 3 is contained in the groove 6; The downside of lid 1 have four with the relative fore-set 4 of support column 5 on the base 2; Antenna substrate 8 is the two-sided copper clad plate of common polytetrafluoroethylene, and the front copper coin is reception antenna, antenna lead of this face welding; Fore-set 4 on the lid and the support column 5 on the base are in order to clamping antenna substrate 8, and lid 1 and base 2 are linked in together.

During use, pass the lead bushing 7 of antenna lead from base 2, this antenna box relies on its permanent magnet can be adsorbed on any position that has ferrous metal on the automobile securely.

The utility model has the advantages that:

Simple in structure, make simple, cost is low; Because adopting minimum parts, so the reliability height; Because of easy disassembling, so easy to maintenance; Because of the base of employing with permanent magnet, so installation site in place or the change antenna is very convenient onboard for antenna.
