[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] This utility model is an electrically foldable and deployable antenna structure, which is equipped with an electrically foldable and deployable structure to facilitate the adjustment of the antenna element.

[0029] This technical solution optimizes the antenna element layout and driving method design to achieve rapid and precise antenna unfolding and folding, thereby increasing the antenna's radiation gain and enhancing its mobility.

[0030] like Figure 1 , Figure 6 As shown, the antenna structure adopts a 5-element Yagi antenna form, including an antenna main rod 6, a reflector 1, an active element 2, a regulating element 3, and guide elements 4 and 5 mounted on the antenna main rod 6. It also includes an element unfolding and folding mechanism 7 for unfolding and folding the elements, and an antenna main rod unfolding and folding mechanism 8 for unfolding and folding the antenna.

[0031] In use, the antenna main rod 6 is installed on the antenna bracket 9, and each group of vibrators can be unfolded and folded through the vibrator unfolding and folding mechanism 7; the antenna main rod 6 can be unfolded and folded through the antenna main rod unfolding and folding mechanism 8.

[0032] In specific implementation, the reflecting oscillator 1, the regulating oscillator 3, and the guiding oscillators 4 and 5 are preferably type I oscillators, while the active oscillator 2 is a type X oscillator.

[0033] like Figure 2 As shown, there are two reflector oscillators 1, one on the left and one on the right, evenly distributed on both sides of the main rod. The oscillators are fixed to the main rod by the oscillator fixing seat and the oscillator connecting piece.

[0034] like Figure 3As shown, the active vibrator 2 is the most important structure of the Yagi antenna. The vibrator is installed on the main rod through the vibrator mounting base and the vibrator connector. Since the active vibrator needs to be fed, the vibrators on the left and right sides are insulated and isolated from the main rod through the dielectric block.

[0035] like Figure 4 As shown, the adjusting element 3 is the adjustment structure of the Yagi antenna, used to adjust the matching of the Yagi antenna and optimize the standing wave index parameters. The element is fixed to the main rod through the element fixing seat and the element connecting piece.

[0036] like Figure 5 As shown, the guiding oscillators 4 and 5 guide the radiation direction to improve the radiation gain. The gain effect has a parabolic relationship with the number of oscillators. Two sets of guiding oscillators can be installed to increase the gain effect. Each set of guiding oscillators consists of two oscillators on the left and two on the right, for a total of two sets of four oscillators, evenly distributed on both sides of the main rod.

[0037] like Figure 6 As shown, the antenna main rod 6 is the main support structure of the Yagi antenna. Both the active and passive elements are mounted on the main rod via element mounting brackets. To ensure the strength of the main rod under wind and gravity loads, diagonal bracing 10 is added to the antenna main rod 6 for support and to improve strength. Specifically, the diagonal bracing 10 consists of a diagonal brace and a diagonal brace. Furthermore, a rigid fiberglass diagonal brace is added to the main rod on the heavier active element side to ensure strength under wind and gravity loads, while a flexible diagonal brace is added to the lighter antenna main rod on the other side, increasing strength without affecting the unfolding and folding of the antenna main rod.

[0038] In its implementation, the oscillator unfolding and folding mechanism 7 includes an oscillator diagonal tie rod 11, a lead screw and slider assembly, and a drive motor. The oscillator diagonal tie rod serves as the antenna connection mechanism, and the lead screw and slider assembly serves as the antenna's motion mechanism. The lead screw is a reversible lead screw, driven by the drive motor to move the module horizontally, thus enabling the oscillator to open and fold. One end of the oscillator diagonal tie rod 11 is connected to the slider, and the other end is connected to the oscillator; the slider slides on the lead screw; the drive motor drives the lead screw to rotate. The oscillator can rotate relative to the main rod via the oscillator mounting base.

[0039] The main pole unfolding and folding mechanism 8 includes a main pole unfolding, folding, and flipping mechanism and a drive motor. The main pole unfolding, folding, and flipping mechanism includes a main pole connector rotating shaft. The main pole connector is connected to the main pole 6, and the rotating shaft is directly connected to the output of a speed reducer, which is driven by the drive motor. More specifically, the antenna main pole 6 includes two symmetrically arranged sections. The antenna main pole is connected via the antenna main pole connector and then mounted on the rotating shaft via the antenna main pole connector; the rotating shaft is powered by the drive motor via the speed reducer.

[0040] The specific implementation process is as follows:

[0041] 1. Antenna element layout design: Based on the antenna element function and scheme design, and combined with simulation results, determine the layout of the element on the antenna main rod to increase signal reception or transmission efficiency.

[0042] 2. Antenna Weight Requirements Design: Based on the weight requirements of the antenna structure specifications, the Yagi antenna was designed to be lightweight. The main antenna mast bears the overall weight of the antenna and is relatively long; therefore, it is made of 7075 aluminum alloy, which is strong yet lightweight. The antenna vibrator needs to maintain good toughness and not break under wind and gravity, so 6061 aluminum alloy was used. The overall design achieves maximum weight reduction while ensuring strength.

[0043] 3. Antenna main mast unfolding and folding mechanism design: The antenna main mast unfolding and folding motor drives the reducer, and the output shaft of the reducer is connected to drive the rotating shaft on the main mast unfolding and folding flipping mechanism, thereby driving one main mast connector to flip one side of the main mast 180°, realizing the unfolding of the antenna main mast.

[0044] 4. Antenna element unfolding and folding mechanism design: By driving the unfolding and folding motor, the lead screw is rotated. The rotation of the lead screw is converted into the horizontal movement of the nut, which drives the diagonal tie rod mechanism of the antenna element, thereby unfolding the front and rear elements together. There are two sets of antenna element unfolding and folding mechanisms, distributed at both ends of the main rod. The reflector, active element and adjustment element share one set, and the two guide elements share one set. They can be unfolded at the same time, reducing the opening time and improving the antenna utilization efficiency.

[0045] 5. Wind and sand protection and rainproof design for the lead screw: An accordion cover and a metal shell are added to the lead screw slider. The accordion cover can slide with the nut to ensure the seal during the movement. The metal shell is mainly installed on the drive motor and the middle non-moving parts, thereby ensuring the seal of the entire oscillator unfolding and folding mechanism.

[0046] 6. Installation and Debugging: Assemble the antenna main mast, antenna elements, etc., according to the design plan, ensuring reliable connections and accurate positioning of all components. Test and debug the assembled motorized folding and deployable antenna structure to ensure it meets design requirements.

[0047] 7. On-site installation: Install the debugged motorized folding antenna in the designated location to ensure that the whole system can operate stably and reliably.

[0048] This technical solution is an antenna device with rapid deployment and storage functions, good electrical performance, stable and reliable rapid deployment and retrieval capabilities, and good mobility.

[0049] This technical solution increases the number of guiding elements, thereby enhancing the antenna's ability to receive and transmit signals.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
