Description

Technical Field

[0001] This utility model relates to the field of antenna array technology, specifically to a directional adjustable PKE antenna array structure. Background Technology

[0002] Currently, an antenna array refers to an antenna system consisting of multiple identical antenna elements arranged according to a specific pattern, and whose predetermined radiation characteristics are achieved by adjusting the current amplitude and phase of each element. An antenna array consists of no fewer than two antenna elements with the same structure and size, which are arranged in a regular or random manner to form linear arrays, area arrays, or three-dimensional arrays such as spherical arrays and conformal arrays. The arrangement method and the excitation state of the array elements together determine the overall performance of the array.

[0003] Currently, antenna arrays are fixed and cannot be changed in shape to change direction, which limits the performance of antenna array communication and detection systems and results in weak reception of signals from other directions. Utility Model Content

[0004] This invention provides a directional adjustable PKE antenna array structure. Through support rods, mounting plates, sliding bases, connecting rods, and internally threaded square tubes, the internally threaded square tubes can be raised and lowered by rotation, thereby moving the four connecting rods upward and causing the four mounting plates to swing in all directions, thus changing the structure of the antenna array itself and improving the signal reception range.

The outer wall of the sliding base is slidably embedded in the fixed rod. One end of each of the four connecting rods is rotatably mounted on the sliding base, and the other end of each of the four connecting rods is rotatably mounted on one of the four mounting plates.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a directionally adjustable PKE antenna array structure, comprising:

[0023] A fixed rod 1 is provided with four support rods 2 fixed at equal intervals along the circumference of the upper surface of the outer wall of the fixed rod 1. Four mounting plates 3 are rotatably provided at the ends of the four support rods 2 that are away from the fixed rod 1.

[0024] The adjustment structure is located inside the fixed rod 1 and on the four mounting plates 3;

[0025] The adjustment structure includes a sliding base 4, four connecting rods 5 and an internally threaded square tube 6. The outer wall of the internally threaded square tube 6 is slidably embedded in the fixed rod 1, and the top end of the internally threaded square tube 6 is fixedly mounted on the sliding base 4. The outer wall of the sliding base 4 is slidably embedded in the fixed rod 1. One end of each of the four connecting rods 5 is rotatably mounted on the sliding base 4, and the other end of each of the four connecting rods 5 is rotatably mounted on one of the four mounting plates 3.

[0026] In this implementation scheme: the four support rods 2 can be fixed at equal intervals along the circumference by the fixed rod 1. The four support rods 2 respectively make the four mounting plates 3 swing only at the connection of the support rods 2. During the lifting and lowering process, the internal thread square tube 6 will drive the sliding base 4 to lift and slide within the fixed rod 1, thereby causing the four connecting rods 5 to spread outward and act on the four mounting plates 3 respectively, causing the four mounting plates 3 to swing in all directions, thereby changing the structure of the antenna array itself and improving the signal reception range.

[0027] Specifically, a fixing plate 7 is fixedly provided at the bottom end of the fixing rod 1, and multiple mounting holes 8 are provided at equal intervals along the circumferential surface of the outer wall of the fixing plate 7.

[0028] In this embodiment: the fixing plate 7 can fix the fixing rod 1, and multiple mounting holes 8 are used for installation and fixation.

[0029] Specifically, a control motor 9 is installed on the top of the fixing plate 7, and the outer wall of the control motor 9 is slidably embedded in the fixing rod 1.

[0030] In this embodiment: the output end of the motor 9 drives the threaded rod 10 to rotate when the motor 9 is powered on.

[0031] Specifically, the output end of the control motor 9 is fixedly provided with a threaded rod 10, the outer wall of the threaded rod 10 is rotatably embedded in the fixed rod 1, and threadedly embedded in the internally threaded square tube 6.

[0032] In this embodiment: by rotating the threaded rod 10, the internally threaded square tube 6 can slide up and down using the thread. The internally threaded square tube 6 is affected by its shape and cannot rotate inside the fixed rod 1, so it can only move up and down.

[0033] Specifically, antenna array bodies 11 are fixedly embedded in the top of the outer wall of the four mounting plates 3.

[0034] In this embodiment, the performance of the wireless system can be significantly improved by utilizing the collaborative operation of multiple units through the antenna array 11.

[0035] Specifically, four slots are provided at equal intervals along the circumference of the upper surface of the outer wall of the fixing rod 1.

[0036] In this embodiment, the four slots on the fixed rod 1 allow the four connecting rods 5 to swing freely in all directions during the lifting and lowering process.

[0037] In use, the fixing plate 7 can fix the fixing rod 1, and multiple mounting holes 8 are used for mounting and fixing. When the control motor 9 is powered on, the output end drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 allows the internally threaded square tube 6 to slide up and down using the thread. Due to its shape, the internally threaded square tube 6 cannot rotate within the fixing rod 1, so it can only move up and down. The antenna array 11 can significantly improve the performance of the wireless system by working in tandem with multiple units. The fixing rod 1 can fix the four support rods 2 at equal distances along the circumference. The four support rods 2 respectively allow the four mounting plates 3 to swing only at the connection points of the support rods 2. During the lifting and lowering process, the internally threaded square tube 6 will drive the sliding base 4 to slide up and down within the fixing rod 1, thereby causing the four connecting rods 5 to spread outward and act on the four mounting plates 3 respectively, causing the four mounting plates 3 to swing in all directions. The four slots on the fixing rod 1 allow the four connecting rods 5 to swing in all directions without obstruction during the lifting and lowering process, thereby changing the structure of the antenna array itself and improving the signal reception range.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
