[0030] Embodiment 1

[0031] Please refer to Figures 1-6 , this embodiment provides a tile-type phased array antenna, which includes an antenna assembly 10, a module assembly 12, a power supply assembly 13, and a signal processing assembly 14 stacked in sequence along the same direction. The antenna assembly 10 includes a plurality of sub-units 11 stacked in sequence along the same direction. All the sub-units 11 have coaxial first through-holes, and all the sub-units 11 are connected by a first bolt assembly 21 passing through the first through-holes. At least two sub-units 11 have coaxial second through-holes, and a second bolt assembly 22 passes through the second through-holes to connect at least two sub-units 11; after the antenna assembly 10, the module assembly 12, the power supply assembly 13, and the signal processing assembly 14 form an integral body, they are connected by a third bolt assembly 23.

[0032] In this embodiment, the antenna assembly 10 is the core part of the phased array antenna, which determines the radiation performance and beam control accuracy of the antenna. It is composed of multiple radiation elements. By controlling the phase and amplitude of each radiation element, the control of the beam direction, shape, and amplitude can be achieved. The module assembly 12 may include multiple functional modules, such as a transceiver module, a frequency conversion module, a filtering module, etc. The module assembly 12 is responsible for processes such as signal transmission, reception, frequency conversion, and filtering; it realizes functions such as signal modulation, demodulation, amplification, and frequency conversion to ensure the quality and stability of the signal during transmission. The power supply assembly 13 is the energy supply center of the tile phased array antenna and usually includes a power module, a battery, a voltage regulator, etc., which provides stable and reliable power supply for the entire antenna system to ensure that each component can work properly. The signal processing assembly 14, that is, the information processing assembly, is mainly responsible for signal processing and control. It usually includes modules such as a signal generator, a processor, and a controller; it is responsible for generating, processing, and transmitting signals to ensure that the antenna system can accurately send and receive signals.

[0033] For ease of understanding, refer to Figure 1 and Figure 3 , Figure 2 In, L1, L2, L3, and L4 respectively represent the antenna assembly 10, the module assembly 12, the power supply assembly 13, and the signal processing assembly 14. The antenna assembly 10, the module assembly 12, the power supply assembly 13, and the signal processing assembly 14 are stacked in sequence in the upward direction. When installing the antenna assembly 10, first install the second bolt assembly 22. When there are 8 sub-assemblies of the antenna assembly 10 stacked from bottom to top, the second bolt assembly 22 can be multiple bolts of the same length. At this time, the second bolt connects the two middle sub-assemblies; the second bolt can include multiple bolts of the first length and multiple bolts of the second length. At this time, the bolts of the first length connect the two middle sub-assemblies, and the bolts of the second length connect the four middle sub-assemblies; the second bolt can include multiple bolts of the first length, multiple bolts of the second length, and multiple bolts of the third length. At this time, the bolts of the first length connect the two middle sub-assemblies, the bolts of the second length connect the four middle sub-assemblies, and the bolts of the third length connect the six middle sub-assemblies. Then connect the antenna assembly 10 through the first bolt assembly 21, and finally connect the antenna assembly 10, the module assembly 12, the power supply assembly 13, and the signal processing assembly 14 through the third bolt.

[0034] Embodiment 2

[0035] Based on Embodiment 1, this embodiment provides a specific connection method for an antenna assembly 10, a module assembly 12, a power supply assembly 13, and a signal processing assembly 14, including: The antenna assembly 10 and the module assembly 12 are connected by a fourth bolt assembly 24, the module assembly 12 and the power supply assembly 13 are connected by a fifth bolt assembly 25, the power supply assembly 13 and the signal processing assembly 14 are connected by a sixth bolt assembly 26, and the module assembly 12, the power supply assembly 13, and the signal processing assembly 14 are connected by a seventh bolt assembly 27.

[0036] In this embodiment, by adding connection mechanisms to the module assembly 12, the power supply assembly 13, and the signal processing assembly 14, bolt connections of single layers and each layer are realized through the fourth bolt assembly 24, the fifth bolt assembly 25, the sixth bolt assembly 26, and the seventh bolt assembly 27, further improving the connection structure stability of the overall antenna assembly 10, module assembly 12, power supply assembly 13, and signal processing assembly 14.

[0037] Embodiment 3

[0038] As an alternative implementation, referring to Figure 3 and Figure 4 , this embodiment provides a specific structure of a bolt assembly 30, including: The bolt assembly 30 includes a screw rod assembly 31 and a first nut 32 and a second nut 33 located at both ends of the screw rod assembly 31; The first nut 32 is fixedly connected to the screw rod assembly 31, and the second nut 33 is detachably connected to the screw rod assembly 31.

[0039] In this embodiment, through the connection method of the screw rod assembly 31, the first nut 32, and the second nut 33, it is convenient to vertically connect the antenna assembly 10, the module assembly 12, the power supply assembly 13, and the signal processing assembly 14 detachably by the bolt assembly 30. The screw rod assembly 31 passes through the mounting holes opened along the thickness direction on the antenna assembly 10, the module assembly 12, the power supply assembly 13, and the signal processing assembly 14. The first nut 32 and the second nut 33 are respectively located at both ends of the structure to be connected, and the first nut 32 and the second nut 33 are clamped for fixation. The first nut 32 is fixedly connected to the screw rod assembly 31, which is convenient for fixing the first nut 32 and the screw rod to install the second nut 33 onto the screw rod assembly 31.

[0040] Embodiment 4

[0041] As an alternative implementation, referring to Figure 3 and Figure 4, this embodiment provides a specific structure of a bolt assembly 30, including: the bolt assembly 30 includes a screw rod assembly 31 and a first nut 32 and a second nut 33 located at both ends of the screw rod assembly 31; coaxially arranged through holes form a channel for the through hole of the screw rod assembly 31, and the through holes at both ends of the channel are first counterbores, and the two first counterbores are used to accommodate the first nut 32 and the second nut 33 respectively.

[0042] In the embodiment, by setting both ends of the channel as first counterbores, installation spaces are reserved for the first nut 32 and the second nut 33 through the first counterbores. After the first nut 32 and the second nut 33 are installed, the first nut 32 and the second nut 33 can be located within the first counterbores, realizing that both the left and right surfaces of each part are flat, and there is no concave-convex structure at the joint surface, enabling the thrust of the bolt assembly 30 to be transmitted as much as possible, and at the same time, the deformation of a single part itself is limited, further improving the structural stability.

[0043] Embodiment 5

[0044] As an alternative implementation, referring to Figure 3 and Figure 4 , this embodiment provides a specific structure of a bolt assembly 30, including: the screw rod assembly 31 includes a first screw rod 311 and a second screw rod 312. One end of the first screw rod 311 is connected to the first nut 32, and the other end has a threaded hole extending axially. The second screw rod 312 has a first thread section and a second thread section with opposite helix directions. The first thread section is used to cooperate with the threaded hole, and a gasket 50 is also threadedly connected to the first thread section. The second thread section is used to cooperate with the second nut 33. The gasket 50 and the second nut 33 have coaxially arranged limiting holes, and a limiting pin 60 is detachably arranged in the limiting holes.

[0045] Since it is necessary to connect the antenna assembly 10, the module assembly 12, the power supply assembly 13, and the signal processing assembly 14, as well as each internal sub-unit 11 of the antenna assembly 10, the lengths of the bolt assemblies 30 connecting each module are different, and it is necessary to customize multiple different specifications of bolt assemblies 30, which is inconvenient to use. In this embodiment, the overall length composed of the first screw rod 311 and the second screw rod 312 is adjustable, and only a bolt assembly 30 of the same specification is required to realize the connection of components with multiple different lengths. During use, the first nut 32 is fixedly connected to the first screw rod 311, and the first nut 32 rotates synchronously with the first screw rod 311. First, connect the lower end of the second screw rod 312 to the threaded hole of the first screw rod 311 (at this time, the gasket 50 and the second nut 33 are not installed on the second screw rod 312), then assemble the component to be connected onto the first screw rod 311 and the second screw rod 312, and then assemble the gasket 50 so that the position of the gasket 50 is on the first thread section of the second screw rod 312 ( Figure 4as shown in M in the figure); then assemble the second nut 33 so that the second nut 33 is located on the second screw section of the second screw 312 ( Figure 4 as shown in N in the figure). After the limiting holes of the gasket 50 and the second nut 33 are aligned, insert the limiting pin 60 to restrict the circumferential rotation of the gasket 50 and the second nut 33. Since the gasket 50 and the second nut 33 are fixedly connected by the limiting pin 60, when an external force for clockwise rotation is applied to the second nut 33, the gasket 50 will also rotate clockwise synchronously. When the first nut 32 rotates clockwise, since it is connected to the forward thread, it will try to move to the right (assuming the screw is placed from left to right). At the same time, the gasket 50 is also rotating clockwise, but since it is connected to the reverse thread, it will try to move to the left. They cannot move relative to each other, so in fact they will "get stuck" on the screw and cannot move. Since the gasket 50 and the second nut 33 are fixedly connected and try to move in opposite directions, they will generate equal but opposite torques on the screw. These two torques will cancel each other out, resulting in the screw itself not being subjected to a net torque, so the screw will not rotate relative to each other. At this time, it is convenient to apply an axial external force to the second screw 312 through the second nut 33, so that the second screw 312 can move relative to the first screw 311, thereby realizing the overall adjustment of the first screw 311 and the second screw 312.

[0046] Embodiment 6

[0047] On the basis of Embodiment 5, this embodiment provides a specific structure of the cooperation between the limiting pin 60 and the second nut 33, including: the second nut 33 has a plurality of limiting holes, and all the limiting holes are annularly distributed.

[0048] Optionally, the limiting hole on the second nut 33 is the second counterbore 40, the end of the limiting pin 60 is connected with a limiting block 61, and the height of the limiting block 61 is less than the height of the sinking section of the second counterbore 40.

[0049] Optionally, the outer diameter of the limiting pin 60 is less than the inner diameter of the second counterbore 40.

[0050] Optionally, the limiting pin 60 and the gasket 50 are in threaded fit.

[0051] In this embodiment, by providing a plurality of limiting holes, connection can be made through the limiting pin 60, improving the connection stability between the second nut 33 and the gasket 50. By providing the second counterbore 40, the limiting block 61 of the limiting pin 60 can be accommodated in the second counterbore 40, facilitating the application of a circumferential external force to the second nut 33 through a tool. By the threaded fit between the limiting pin 60 and the gasket 50, it is convenient to maintain the distance between the gasket 50 and the second nut 33.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
