[0002] In order to adaptively adjust the array size based on the application scenario, the existing radar antenna array is mostly a spliced structure composed of several sub-arrays arranged in an array.
[0003] Each sub-array in this type of patchwork radar antenna array is independently configured. When the array needs to be moved to a different detection area, splitting the array into its sub-arrays, moving them to the target detection area, and then reassembling them is a complex and time-consuming process, and can also easily damage the sub-arrays. Therefore, existing techniques typically move the entire large array as a whole.
[0004] However, the inventors found that this method of moving the entire large-scale array as a whole has the disadvantage of being difficult to transport, and the array is also very likely to be damaged during transportation, thus affecting the smooth implementation of subsequent detection tasks.

[0019] Beneficial effects:
[0020] This technical solution designs a new type of iteratively spliced foldable radar array to improve the technical defects of existing large-sized radar arrays, such as the difficulty in transportation and the susceptibility to damage.
[0021] The radar array includes: a number of sub-arrays, a number of rotating parts corresponding to each sub-array, and a number of supporting parts. The sub-array includes a main body and a frame, and the frame is adapted to be mounted on the main body.

DETAILED DESCRIPTION
[0029] To further clarify the objectives, technical solutions, and advantages of the embodiments of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0031] To adapt the array size based on the application scenario, existing radar antenna arrays are often constructed using a patchwork structure consisting of several sub-arrays arranged in an array. However, each sub-array in an existing patchwork radar antenna array is independently arranged. When the array needs to be moved to change the detection area, the entire large array must be moved as a whole. This not only makes transportation difficult, but also makes it prone to damage during transportation. Therefore, this embodiment aims to provide an iteratively spliced foldable radar array to address the aforementioned technical drawbacks of existing patchwork radar arrays.
[0032] The following is a further detailed introduction to the iteratively spliced foldable radar array disclosed in the present invention in conjunction with the embodiments shown in the accompanying drawings.
[0033] Combine Figures 1-2 As shown, the array surface includes: a plurality of sub-arrays 1, a plurality of rotating parts 2 and a plurality of supporting parts 3 corresponding to each sub-array.
[0034] In terms of specific structural design, the sub-array 1 includes a main body 11 and a frame 12. Specifically, the frame 12 is adapted to be fixed to the main body 11.
[0035] The rotating member 2 includes a plurality of rotating shafts 21, a plurality of gears 22, and a plurality of connecting pieces 23. Specifically, each rotating shaft 21 is vertically fixed to the end of any side wall of the frame 12, and each gear 22 is sleeved on the rotating shaft 21 in a one-to-one correspondence. The adjacent gears 22 on two adjacent frames 12 are meshed with each other, and each connecting piece 23 is sleeved on the corresponding rotating shafts 21 with the meshed gears 22.
[0036] The support member 3 includes a plurality of telescopic rods 31 and a plurality of fixing pins 32. Specifically, each fixing pin 32 is vertically fixed to either side of the central axis of any side wall of the frame 12. Two telescopic rods 31 arranged in the same group are movably connected at adjacent ends, and the free ends are movably connected to two fixing pins 31 located on the same side of two adjacent frames 12.
[0037] During specific implementation, based on the above-mentioned radar array, when sub-array splicing is required, for two sub-arrays 1 that need to be deployed adjacent to each other, it is only necessary to provide gears 22 and connecting pieces 23 on the rotating shafts 21 on the adjacent sides of the two frames 12 of the two sub-arrays 1, and to achieve meshing of the gears 22 on the two frames 12 to achieve the splicing of the two sub-arrays 1; and the two sub-arrays 1 can be folded by rotating the gears 22. At the same time, telescopic rods 31 are deployed correspondingly on the side walls that are not opposite to the adjacent sides of the two frames 12 through fixing pins 32, so as to provide buffering when the sub-arrays are folded and unfolded, and avoid collision of sub-arrays due to excessive speed. At the same time, it is also possible to limit the sub-arrays when they are folded to avoid damage caused by shaking of the folded sub-arrays 1. Furthermore, the folding structure between the two sub-arrays is used as the basic folding unit to achieve a foldable splicing setting of the target number of sub-arrays. Specifically, as Figure 1 This is a schematic diagram of the structure of two sub-arrays that can be folded and spliced, as shown in Figure 2 That is a schematic diagram of the structure of three sub-arrays that can be folded and spliced.
[0038] As a specific embodiment, the telescopic rod 31 is a hydraulic rod. The telescopic rod 31 can be extended or shortened under the action of an internal hydraulic system.
[0039] As another specific embodiment, the telescopic rod 31 may also be composed of a main rod and a sleeve. Specifically, the main rod and the sleeve are fitted together, with a protrusion on the outer wall of the main rod and a groove on the inner wall of the sleeve. The protrusions and the grooves are engaged in a one-to-one correspondence. The engagement of the protrusions and grooves at the corresponding positions allows the telescopic rod 31 to be fixed at a desired length.
[0040] To improve the reliability of the overall radar array structure, the rotating element 2 includes several auxiliary shafts 24. Specifically, the corresponding connecting piece 23 includes a spare end 23a, which protrudes from the mating gear 22 and is arranged parallel to the adjacent frame 12. The auxiliary shaft 24 passes through the spare end 23a and is inserted into the frame 12.
[0041] In order to install the rotating member 2 and the supporting member 3 as needed, thereby achieving horizontal or vertical expansion of the sub-array, the rotating shaft 21, the fixing pin 32, and the auxiliary shaft 24 are all detachably mounted. Specifically, in this embodiment, the detachable mounting method is to thread the rotating shaft 21, the fixing pin 32, and the auxiliary shaft 24 into the frame.
[0042] To prevent damage to the array surface caused by collisions between the sub-arrays 1 and the main body 11 when folding or unfolding, the array surface is provided with a plurality of buffers, each of which is attached to each side edge of the frame 12. These buffers thus provide a cushioning effect against potential collisions. Specifically, the buffers can be rubber strips, foam strips, or silicone strips. In this embodiment, the buffers are specifically rubber strips.
[0043] Similarly, in order to prevent the main body 11 from being hit and causing damage to the array surface when the sub-array 1 is folded or unfolded, the main body 11 is embedded in the frame 12 to avoid direct collision with the main body 11.
[0044] In summary, this embodiment designs a new type of foldable radar array, which can be folded during transportation to reduce the difficulty of transportation. The radar array does not introduce new technical problems, and corresponding structural design is carried out to further prevent the radar array from being damaged during transportation.
[0045] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
