Problems solved by technology
[0004] In order to solve the problem that the traditional whip antenna cannot be deployed in an orderly manner, and the deployment process is uncontrollable, the present invention proposes a new type of whip antenna deployment mechanism with high storage ratio and orderly deployment, which uses a scroll spring to drive the rotating shaft to realize a whip antenna. Dimensional and orderly unfolding, the unfolding process is stable and controllable, and the unfolding accuracy is high

Embodiment Construction
[0036] Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0037] Such as figure 1 and figure 2 As shown, the high storage ratio orderly deployment whip antenna deployment mechanism in this embodiment includes a housing, a pin puller, a rotating disk, a shaft, an antenna unit and a spiral spring.
[0038] A pyrotechnic pin puller is installed on the top surface of one side of the housing, and there is a lightening hole inside; the inner side of the other side is divided into a rotating disk accommodation chamber and a scroll spring accommodation chamber. The rotating disc accommodation chamber and the vortex spring accommodation chamber are arranged up and down, separated by a partition with a through hole.
[0039] Such as Figure 6 As shown, the antenna unit is a whip antenna with an arched section after deploym...

The invention proposes a novel whip antenna deployment mechanism with high storage ratio and orderly deployment, which includes a housing, a pin puller, a rotating disk, a shaft, an antenna unit, and a vortex spring; the antenna unit is a whip antenna with an arched cross-section after deployment; The center of the disk has a through hole that matches the shaft, and the upper part has a pin shaft matching hole that cooperates with the pin puller to release the degree of freedom of rotation of the rotating disk. The cross-section corresponds to the arch; the antenna unit is wound on the antenna winding section as a whole; after the rotating disk and the shaft are assembled, they are installed in the housing as a whole; Release to expand. The invention adopts the scroll spring to drive the rotating shaft to realize the one-dimensional and orderly deployment of the whip antenna, the deployment process is stable and controllable, and the deployment precision is high, and by using a new deployment method and an arched section, the problem caused by the large size and light weight of the antenna is solved. Low stiffness problem.
Description
technical field [0001] The invention relates to the technical field of whip antennas, in particular to a novel whip antenna deployment mechanism with high storage ratio and orderly deployment. Background technique [0002] Whip antennas (also known as monopole antennas) are generally used for low-frequency electric field tests below 50MHz, because of their rod-like shape and small size, they are widely used, such as in communications, broadcasting, television, radar, navigation, telemetry, remote sensing It has a wide range of applications in engineering technology. When the whip antenna is used in scenarios such as ships, vehicles, or on the ground, due to limited space or mobile work in these application scenarios, the antenna is often required to be miniaturized, lightweight, and easy to install. Moreover, with the gradual development of lunar exploration, due to the unique environment on the back of the moon, it is more advantageous to carry out low-frequency radio obse...
