[0024] The array system comprises a bottom plate, a plurality of subarray skeletons, a plurality of subarrays, a plurality of radomes and a plurality of fixing parts. The subarray skeletons are arranged in a matrix and fixed on the bottom plate, and the subarrays and the radomes are arranged one-to-one corresponding to the subarray skeletons; the subarrays are arranged in the subarray skeletons, and the radomes are arranged on the subarray skeletons; the fixing parts are arranged on the mounting side of the subarray skeletons and comprise a transmission assembly and a bolt assembly.

[0036] The existing sub-arrays in the radar antenna array surface are fixed and installed by screws. The currently commonly used radar antenna array surface generally includes several dozen or even hundreds of sub-arrays, which further leads to the fixation of the sub-arrays and the sub-array skeletons by screws, and the low installation and disassembly efficiency when the screws are removed for sub-array disassembly. At the same time, the size of the screws is small, and if they are accidentally dropped during operation, they may affect the sub-arrays or subsequent detection. Based on this, the present embodiment aims to provide a radar antenna array surface system to improve the above technical defects.

[0037] The radar antenna array surface system disclosed by the present application will be further specifically introduced below in combination with the embodiments shown in the drawings.

[0038] Considering that the disassembly and installation of the sub-arrays need the cooperation of the antenna cover, specifically, the antenna cover needs to be opened before the installation and disassembly of the sub-arrays, and the antenna cover needs to be closed after the installation of the sub-arrays. Based on this, the following array surface system is designed.

[0039] Combination Figures 1 to 3 As shown in the figure, the array system includes a base plate 1, a plurality of subarray skeletons 2, a plurality of subarrays 3, a plurality of radomes 4 and a plurality of fixing parts 5. Each subarray skeleton 2 is fixed on the base plate 1 in a matrix arrangement, and each subarray 3 and radome 4 is arranged in one-to-one correspondence with the subarray skeleton 2. Among them, the subarray 3 is placed in the subarray skeleton 2, and the radome 4 is arranged on the subarray skeleton 2.

[0040] Specifically, for the fixing part 5, it is embedded in the mounting side of the subarray skeleton 2, including a transmission assembly and a latch assembly that cooperate with each other.

[0041] In the specific structural design, the transmission assembly includes a first gear 51, a second gear 52, a third gear 53 and a transmission rod 54. Among them, the transmission rod 54 includes a screw rod and a first sleeve that are sleeved and threadedly matched. The first gear 51, the second gear 52 and the third gear 53 are in meshing cooperation in turn, and the planes where the first gear 51, the second gear 52 and the third gear 53 rotate are perpendicular to each other. The third gear 53 is also fixedly sleeved on the first sleeve.

[0042] The latch assembly includes a second sleeve 55, a first elastic member, a first latch 56 and a connecting rod 57. The first elastic member and the first latch 56 are both placed in the second sleeve 55. Among them, one end of the first elastic member abuts against the inner side wall of the second sleeve 55, and the other end abuts against one end of the first latch 56; the free end of the first latch 56 protrudes out of the second sleeve 55. The connecting rod 57 is inserted into the second sleeve 55 with interference, and has a degree of freedom of movement along the length direction of the side peripheral wall; at the same time, one end of the connecting rod 57 is fixed perpendicularly to the transmission rod 54, and the other end is fixed perpendicularly to the first latch 56. In this embodiment, the first elastic member is a spring.

[0043] In order to avoid the movement of the third gear 53 to reduce the control effect on the movement of the latch assembly, a fixing seat 58 is also provided, and the third gear 53 is placed in the fixing seat 58; so as to avoid the axial movement of the third gear 53.

[0044] In order to limit the movement of the fixing part 5, the fixing part 5 also includes a limiting member 59. The limiting member 59 is arranged between the transmission assembly and the latch assembly, including a cross rod 59a and a limiting block 59b; among them, the cross rod 59a is parallel to the second sleeve 55, is fixedly sleeved on the connecting rod 57, and is movably inserted into the subarray skeleton 2; among them, both ends of the connecting rod protrude out of the subarray skeleton, and the limiting block 59b is fixedly arranged.

[0045] The fixed part cooperates with other parts as follows: the mounting side of the radome 4 cooperates with the first gear 51; the outer side wall of the subarray 3 is provided with a first insertion hole, which cooperates with the spare end of the first insertion pin 56.

[0046] In a specific implementation, in an initial state, i.e., when the subarray 3 is placed in the subarray framework 2, the first insertion pin 56 cooperates with the first insertion hole to fix the subarray 3. If the subarray 3 needs to be disassembled, the radome 4 needs to be opened, at this time, the first gear 51 is rotated during the opening of the radome 4, and then the second gear 52 and the third gear 53 are sequentially rotated; the third gear 53 drives the screw rod threaded with the first sleeve to move to the mounting side of the radome 4, and then drives the first insertion pin 56 to move to the mounting side of the radome 4 under the action of the connecting rod 57 fixed with the screw rod, thereby releasing the locking and fixing of the subarray 3 between the first insertion pin 56 and the first insertion hole. During the installation of the subarray, the radome 4 is pressed and closed, and the first elastic member gradually recovers the deformation, so that the first insertion pin 56 cooperates with the first insertion hole again to fix the subarray 3.

[0047] In order to further improve the installation efficiency of the subarray, as a specific implementation, the bottom plate 1 is provided with a limiting column, and the bottom of the subarray 3 is provided with a limiting hole. The limiting column and the limiting hole one-to-one correspond to each other. At this time, the subarray is preliminarily positioned through the insertion and cooperation of the limiting column and the limiting hole, so as to improve the alignment accuracy when the first insertion pin 56 cooperates with the first insertion hole, and then improve the insertion and cooperation efficiency.

[0048] As another specific implementation, the spare end of the first insertion pin 56 is provided with a chamfer. At this time, even if there is an alignment error between the first insertion pin 56 and the first insertion hole, the first insertion pin 56 can also smoothly slide into the first insertion hole to realize the insertion and cooperation of the two.

[0049] During the disassembly and installation of the subarray, in order to facilitate the opening and closing of the radome 4 to improve the overall operation efficiency, the side of the radome 4 opposite to the mounting side is provided with an operation handle. The operator can use the operation handle as a force point to quickly open and close the radome 4.

[0050] In combination Figure 4As shown, as another specific embodiment, in order to improve the efficiency of opening and closing of the radome 4, and the reliability when closed, the radome 4 is provided with a spliced first sub-cover 41 and a second sub-cover 42, and the mounting side of the first sub-cover 41 and the second sub-cover 42 is provided with the fixed part 5. Wherein, the splicing side of the first sub-cover 41 is provided with a third sleeve 43, a second bolt 44 and a push rod 45, the second bolt 44 is movably arranged in the third sleeve 43, and one end protrudes from the side surface of the first sub-cover 41. The push rod 45 is interference-inserted in the third sleeve 43, and has a freedom degree of movement along the length direction of the side wall of the push rod 45; at the same time, one end of the push rod 45 protrudes from the upper surface of the first sub-cover 41, and the other end is fixed perpendicularly to the second bolt 44. The side surface of the splicing side of the second sub-cover 42 is provided with a second insertion hole, and the second insertion hole is inserted and matched with the second bolt 44. At this time, the reliable connection between the first sub-cover 41 and the second sub-cover 42 can be realized through the insertion and matching of the second bolt 44 and the second insertion hole.

[0051] Further, the splicing side of the first sub-cover 41 is provided with a second elastic member 46; the second elastic member 46 is arranged in the third sleeve 43, and one end abuts against the inner wall of the third sleeve 43, and the other end abuts against the end of the second bolt arranged in the third sleeve. Thus, the reliability of the splicing and fixing between the two sub-covers is further improved. In the embodiment, the second elastic member 46 is a spring.

[0052] At the same time, in order to improve the overall reliability of the fixed part 5, the transmission assembly is provided with a connecting block, the connecting block is arranged on the upper surface of the radome 4, and the screw rod and the connecting rod 57 are fixedly matched through the connecting block.

[0053] Although the present application has been disclosed with reference to the preferred embodiments, it is not intended to limit the present application. Those skilled in the art can make various modifications and improvements without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application shall be subject to the right claim.
