Description

Technical Field

[0001] This utility model relates to a radar motion device, belonging to the field of radar equipment technology. Background Technology

[0002] To maximize the radar's detection range—that is, to expand the detection range from one direction to a hemispherical three-dimensional space centered on itself—a pitch support device is typically used to connect the servo turntable and the radar main unit. Examples include a radar pitch mechanism disclosed in Chinese utility model patent application publication number CN222506547U, and a motion mechanism for a phased array radar disclosed in CN219067210U. However, these devices all have the following drawbacks:

[0003] During rotation or pitching motion, the wiring of the device, such as the cables connecting the radar host and the servo turntable, is exposed. When exposed to the outdoors for a long time, it will affect the service life of the cables and cause problems such as radar detection failure. Utility Model Content

[0004] The present invention aims to provide a radar motion device that solves the problems of short cable life and easy detection failure caused by exposed wiring in existing devices.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A radar motion device includes a servo turntable, a radar host, a telescopic mechanism hinged to the servo turntable and the radar host respectively, a lower ear fixed to the servo turntable, and an upper ear fixed to the radar host; the lower ear and the upper ear are hinged with an open space between them; the lower ear has a lower connecting hole communicating with the interior of the servo turntable, and the upper ear has an upper connecting hole communicating with the interior of the radar host; a cable for electrically connecting the servo turntable and the radar host is provided between the lower connecting hole and the upper connecting hole; a multi-directional deformable flexible element for enclosing the cable in the open space is provided between the lower ear and the upper ear; one end of the multi-directional deformable flexible element is fixed to the lower ear or the servo turntable, and the other end is fixed to the upper ear or the radar host.

[0007] When adjusting the rotational angle detection is required, the servo turntable is driven to rotate. When adjusting the pitch angle detection is required, the telescopic mechanism extends and retracts, causing the radar main unit to rotate relative to the servo turntable around the hinge axis of the lower and upper earpieces. During rotational or pitching movements, the cables electrically connecting the servo turntable and the radar main unit are located in an open space but are enclosed by a multi-directional deformation flexible element, preventing the cables from being exposed to the outside. The multi-directional deformation flexible element deforms along with the radar main unit during pitching, ensuring that the cables remain enclosed. This radar motion device solves the problems of short cable life and easy detection failures caused by exposed wiring in existing devices.

[0008] Furthermore, in order to enhance the aesthetics of the structure and improve the protection of the cables, the lower ear seat is provided with lower cover plates on both sides, which are fixed to the lower ear seat or the servo turntable, and the upper ear seat is provided with upper cover plates on both sides, which are fixed to the upper ear seat or the radar host; the two ends of each multi-directional deformation flexible element are located inside the lower cover plate and the upper cover plate, respectively.

[0009] Furthermore, in order to prevent external rainwater or moisture from entering and damaging the cable, a sealing gasket is provided between one end of the multi-directional deformation flexible element and the lower ear or the servo turntable, and a sealing gasket is provided between the other end of the multi-directional deformation flexible element and the upper ear or the radar host.

[0010] Furthermore, the lower ear seat and the upper ear seat are hinged together by a central shaft, and the end of the lower ear seat or the upper ear seat is provided with a protective cover for covering the central shaft.

[0011] Furthermore, in order to detect the pitch angle in real time, the protective cover is equipped with an angle encoder, and the angle encoder is connected to a display screen.

[0012] Furthermore, in order to limit the range of pitch angles and to protect the radar, a rotation limit block is fixed at the end of the central shaft. A limit switch is provided on one side of the rotation limit block. The limit switch is installed on one side of the lower ear or the upper ear and is connected to the emergency stop.

[0013] Furthermore, for ease of assembly, the upper connecting hole is provided with a connector electrically connected to the radar host, and / or the lower connecting hole is provided with a connector electrically connected to the servo turntable; the cable is electrically connected to the connector.

[0014] Furthermore, the multi-directional deformation flexible element is a corrugated pipe sheet.

[0015] Furthermore, the lower ear seat includes a lower support plate fixed on the servo turntable and lower ear plates fixed at both ends of the lower support plate; the upper ear seat includes an upper support plate fixed on the radar host and upper ear plates fixed at both ends of the upper support plate; the lower ear plates and the upper ear plates are hinged together, and the space between the lower support plate, the lower ear plates, the upper support plate and the upper ear plates is an open space.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] See Figures 1 to 3 This embodiment provides a radar motion device. The radar motion device includes a servo turntable 1, a radar host 2, a telescopic mechanism 3 hinged to both the servo turntable 1 and the radar host 2, a lower lug 4 fixed to the servo turntable 1, an upper lug 5 fixed to the radar host 2, and a multi-directional deformable flexible element disposed between the lower lug 4 and the upper lug 5. The telescopic mechanism 3 is an electric cylinder. The multi-directional deformable flexible element is a corrugated tube sheet 6, or a rectangular corrugated tube.

[0028] Both the lower ear mount 4 and the upper ear mount 5 are conventional ear mount structures, hinged together. Specifically, the lower ear mount 4 includes a lower support plate 41 fixed to the servo turntable 1 and lower ear plates 42 symmetrically fixed to both ends of the lower support plate 41. The upper ear mount 5 includes an upper support plate 51 fixed to the radar host 2 and upper ear plates 52 symmetrically fixed to both ends of the upper support plate 51. The two upper ear plates 52 are respectively hinged to the inner side of the end faces of the two lower ear plates 42, and the hinge assembly is achieved through a central shaft 9 and a heavy-duty bearing 10. After the hinge is completed, an open space is left between the lower support plate 41, the two lower ear plates 42, the upper support plate 51, and the two upper ear plates 52. A lower connecting hole 43 communicating with the interior of the servo turntable 1 is opened in the middle of the lower support plate 41, and an upper connecting hole 53 communicating with the interior of the radar host 2 is opened in the middle of the upper support plate 51. The cable used to electrically connect the servo turntable 1 and the radar host 2 is led out from inside the servo turntable 1, passes through the lower connection hole 43 and extends into the open space, then passes through the upper connection hole 53 from the open space and enters the radar host 2 for electrical connection.

[0029] Corrugated pipe section 6 is used to enclose open spaces, protecting cables within them. See also Figure 2Each open space is enclosed by two corrugated tube segments 6, that is, corrugated tube segments 6 are provided on both the side of the hinged lower ear seat 4 and upper ear seat 5 closest to the telescopic mechanism 3 and the side furthest from the telescopic mechanism 3. The lower end of the corrugated tube segment 6 is fixed to the lower ear seat 4 or the servo turntable 1 with screws, and the upper end of the corrugated tube segment 6 is fixed to the upper ear seat 5 or the radar host 2 with screws.

[0030] To prevent the screws used to install the corrugated tube segments 6 from being exposed and affecting the overall appearance of the radar, upper cover plates 7 and lower cover plates 8 are respectively installed on the outer sides of the upper and lower ends of each corrugated tube segment 6. The lower cover plates 8 are symmetrically located on both sides of the lower lug 4 and are fixed to the lower lug 4 or the servo turntable 1. The upper cover plates 7 are symmetrically located on both sides of the upper lug 5 and are fixed to the upper lug 5 or the radar main unit 2. Both the upper cover plates 7 and lower cover plates 8 are square plates. The upper cover plates 7 and lower cover plates 8 also further enhance the enclosure and protection of the cables.

[0031] To prevent external rainwater or moisture from entering and damaging the cables, sealing gaskets (not shown in the figure) are installed at the contact points between the corrugated tube 6 and the structure. Specifically, a sealing gasket is installed between the lower end of the corrugated tube 6 and the lower lug 4 or the servo turntable 1, and a sealing gasket is installed between the upper end of the corrugated tube 6 and the upper lug 5 or the radar host 2. The sealing gaskets are made of nylon rubber.

[0032] To protect the hinge structure and prevent the central shaft 9 and heavy bearing 10 from rusting or corroding due to exposure, a protective cover 11 is provided on the outer end face of the lower ear plate 42 of the lower ear seat 4. The protective cover 11 covers the end of the central shaft 9 and the heavy bearing 10. At the same time, in order to detect the pitch angle in real time, an angle encoder 12 is provided on the protective cover 11, and the angle encoder 12 is connected to a display screen for observation.

[0033] See Figure 2 To limit the range of the pitch angle and protect the radar, a rotation limit block 13 is fixed at the end of the central shaft 9. A limit switch 14 is installed on one side of the rotation limit block 13, mounted on the end of either the lower ear plate 4 or the upper ear plate 5. In this embodiment, the limit switch 14 is installed on the outer side of the lower ear plate 42 end face of the lower ear plate 4. The limit switch 14 is fixed at a pitch angle of 91°. The limit switch 14 is an inductive proximity switch connected to an emergency stop mechanism. When the angle encoder 12 detects an error or the button for driving the electric cylinder extension / retraction is accidentally pressed, causing the electric cylinder extension rod to overextend and damage the radar host 2, the rotation limit block 13 and the limit switch 14 automatically stop the electric cylinder's movement, thus protecting the radar.

[0034] See Figure 2To facilitate assembly, a quick-connect high-speed aviation connector 15 for electrical connection to the radar host 2 is provided in the upper connection hole 53, and / or a quick-connect high-speed aviation connector 15 for electrical connection to the servo turntable 1 is provided in the lower connection hole 43. During assembly, only a short cable needs to be directly electrically connected to the connector 15, which is convenient and quick.

[0035] The radar motion device achieves 360° azimuth angle detection by driving the servo turntable 1 to rotate; it achieves 0° to 90° pitch angle detection by extending and retracting the electric cylinder, and can pitch the radar host 2 to a horizontal state or to a state perpendicular to the horizontal plane; the installation of corrugated tube 6 and the concealed wiring method achieve the requirements of waterproof, dustproof and salt spray-proof cables.
