Problems solved by technology

[0003] Most of the car antennas in the prior art are hidden. Although this kind of antenna is small and exquisite, its ability to receive signals is weak. Some off-road vehicles use rod antennas. Although the performance is better, the appearance is relatively rough and has no storage function. The rod antenna can only be disassembled when parked, and can not be stored when driving

Embodiment 1

[0032] like Figure 1-Figure 5 As shown, the present embodiment proposes a vehicle overhead concealed antenna, including a lower casing 10, a motor 11, a middle mounting plate 12, an upper casing 15, a hinge base 18, a folding rod 20, a pull wire 30 and an antenna assembly, wherein The lower shell 10 is mounted on the lower part of the middle mounting plate 12 , the upper shell 15 is mounted on the upper part of the middle mounting plate 12 , and the middle mounting plate 12 has a hollow first threading hole 13 corresponding to the position of the lower shell 10 and the upper shell 15 . , the middle mounting plate 12 is provided with a hinge seat 18 at the position corresponding to the first threading hole 13, the lower end of the folding rod 20 is hinged with the hinge seat 18, the antenna assembly is hinged with the upper end of the folding rod 20, and the top of the upper shell 15 is provided with a long hollow 152 and the circular hollow 153 communicated with the long holl...

Embodiment 2

[0046] The vehicle overhead concealed antenna in Embodiment 2 is similar to that in Embodiment 1, and the difference lies in the antenna assembly.

[0047] like Image 6 As shown, the antenna assembly proposed in this embodiment includes an installation base plate 51, a spindle-helix antenna 52 and an antenna installation plate 53. The upper end of the folding rod 20 is hinged to the bottom of the installation base plate 51, and the middle of the installation base plate 51 has a second thread hole 511. The lower end of the spindle helix antenna 52 is connected to the top surface of the installation base plate 51, the upper end of the spindle helix antenna 52 is connected to the bottom surface of the antenna installation plate 53, and the lower end of the spindle helix antenna 52 is connected to the second thread hole 511 of the installation base plate 51. The bottom surface area of ​​the mounting plate 53 is larger than the area of ​​the second threading hole 511 . When the an...

Abstract

The invention relates to the technical field of automobile antennas, in particular to an automobile overhead hidden antenna, which is characterized in that a lower shell is mounted at the lower part of a middle mounting plate, an upper shell is mounted at the upper part of the middle mounting plate, and hollow first threading holes are formed in positions, corresponding to the lower shell and the upper shell, of the middle mounting plate; the position, corresponding to the first threading hole, of the middle mounting plate is provided with a hinge seat, the lower end of the folding rod is hinged to the hinge seat, the antenna assembly is hinged to the upper end of the folding rod, the top of the upper shell is provided with a long-strip hollowed-out part and a circular hollowed-out part communicated with the long-strip hollowed-out part, the motor is mounted in the lower shell, and the lower end of the stay wire is connected with the power end of the motor. The upper end of the stay wire is connected with the antenna assembly. The automobile overhead hidden antenna has a good storage function and can be controlled to be stored or stretched out at any time.

Description

technical field [0001] The present invention relates to the technical field of automobile antennas, in particular to an automobile overhead concealed antenna. Background technique [0002] Antenna is a kind of transformer, which transforms the guided wave propagating on the transmission line into the electromagnetic wave propagating in the unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., which use electromagnetic waves to transmit information, all rely on antennas to work. [0003] In the prior art, car antennas are mostly hidden. Although such antennas are small, their ability to receive signals is weak. Some off-road vehicles use rod antennas. Although they have better performance, their appearance is relatively rough and does n...
