Description

Technical Field

[0001] This invention relates to the field of radar 5G antenna technology, and in particular to a lifting and flipping device for radar 5G antennas. Background Technology

[0002] 5G radar antennas are integrated vehicle-mounted antenna devices that combine radar detection and 5G communication transmission functions. They are widely used in vehicle-mounted mobile platforms such as emergency communication vehicles, command vehicles, monitoring vehicles, and engineering rescue vehicles. To meet the requirements of low center of gravity, small size, and high concealment during vehicle operation, as well as the signal transmission and reception needs of high elevation angle, large height, and wide coverage during operation, these antennas require a lifting and flipping device to quickly switch between storage and operating states.

[0003] Current radar 5G antenna adjustment devices on the market have some defects and are difficult to meet the requirements of integrated vehicle use:

[0004] First, the lifting structure generally adopts the wire rope winch type, which relies on the wire rope to pull to achieve lifting. It has poor rigidity, is easy to sway, has low positioning accuracy, and is prone to problems such as loosening of rope, jamming, wear and breakage after long-term use, resulting in insufficient stability and service life.

[0005] Secondly, they usually lack a dedicated flipping mechanism, and can only achieve single lifting and lowering. They cannot complete the 90-degree flip from horizontal storage to vertical operation. The antenna occupies a lot of space and has poor maneuverability. At the same time, the wire rope structure has no self-locking ability, and it is easy to slip off when the power is off, resulting in insufficient safety. Furthermore, it cannot achieve multi-level synchronous telescopic lifting and lowering, and it is difficult to balance the height adjustment range and stability. Summary of the Invention

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figures 1-10 Example 1: A lifting and flipping device for a radar 5G antenna includes a base plate 1 fixedly installed in the vehicle body compartment by screws. The top outer wall of the base plate 1 is welded with symmetrically distributed reinforcing ribs 2, and the top outer wall of the reinforcing ribs 2 is fixedly connected to a bearing seat 3 by screws. A housing 4 is rotatably connected between the two bearing seats 3 by bearings. The outer walls on both sides of the housing 4 are fixedly connected to mounting plates 5 by screws. An electric push rod 6 is hinged between the mounting plate 5 and the base plate 1. A sleeve 7 is provided through one inner wall of the housing 4, and a telescopic drive mechanism 8 is installed inside the housing 4 at one end of the outer wall of the sleeve 7.

[0037] The telescopic drive mechanism 8 includes a base plate 81, a reducer 82, a drive gear 83, an intermediate wheel 84, a driven gear 85, and a cover plate 86. The cover plate 86 is fixedly connected to the inner wall of the frame 41 on the other side by screws. The base plate 81 is fixedly connected to the outer wall of the cover plate 86 on one side by screws. The reducer 82 is mounted on the outer wall of the base plate 81 on one side. The drive gear 83 is mounted on the output shaft of the reducer 82. The intermediate wheel 84 meshes with the outer wall of the drive gear 83. The driven gear 85 meshes with the outer wall of the intermediate wheel 84. The drive gear 83, the intermediate wheel 84, and the driven gear 85 are all located between the base plate 81 and the cover plate 86. The telescopic drive mechanism 8 also includes a handle 87, which is inserted into the input shaft of the reducer 82.

[0038] With the above scheme, the base plate 1 serves as the mounting base for the entire vehicle, the reinforcing rib 2 enhances the support strength to prevent deformation, the bearing seat 3 provides coaxial rotation support to ensure that the rotation center of the box 4 is consistent, and the electric push rods 6 on both sides synchronously extend and retract to drive the box 4 to achieve 0-90 degree rotation, which meets the requirements for switching between storage and working postures. The sleeve 7 provides protection and guidance for the multi-stage telescopic mechanism 9. The telescopic drive mechanism 8 reduces speed and increases torque through the drive gear 83, the intermediate wheel 84, and the driven gear 85. The handle 87 manually drives the smooth lifting and lowering control. The gear transmission is precise and reliable and has self-locking capability to ensure that the lifting position is fixed and does not slip.

[0039] In this embodiment, the base plate 1, reinforcing rib 2, bearing seat 3, housing 4, mounting plate 5 and electric push rod 6 work together to achieve stable 0-90 degree flipping. When stored, it is placed horizontally to reduce the height of the vehicle body, and when working, it is erected vertically to increase the working height. It has strong support rigidity, smooth rotation and no jamming or shaking, thus solving the defect of traditional devices that do not have a flipping function.

[0040] In embodiment 2, a multi-stage telescopic mechanism 9 is provided on one side of the outer wall of the telescopic drive mechanism 8, and the multi-stage telescopic mechanism 9 is located inside the sleeve 7. The multi-stage telescopic mechanism 9 includes a first-stage telescopic component 91, a second-stage telescopic component 92, a third-stage telescopic component 93, a fourth-stage telescopic component 94, and a fifth-stage telescopic component 95, wherein the first-stage telescopic component 91, the second-stage telescopic component 92, the third-stage telescopic component 93, the fourth-stage telescopic component 94, and the fifth-stage telescopic component 95 are nested sequentially from the inside to the outside.

[0041] Through the above scheme, the multi-stage telescopic mechanism 9 adopts a five-stage structure nested from the inside to the outside to achieve a large stroke telescopic effect. It is small in size when retracted and high in height when extended, which is fully adapted to the installation requirements of limited vehicle space. The all-screw 12 drive replaces the traditional steel wire rope, which has stronger structural rigidity. There is no shaking, no noise, and no slippage during the lifting process. The positioning accuracy and service life are significantly improved. At the same time, synchronous telescopic and consistent movement are achieved.

[0042] In this embodiment, the multi-stage telescopic mechanism 9 realizes five-stage synchronous telescopic lifting and lowering. The rotation of the first-stage lead screw 12 drives all lead screws 12 to move together, and the telescopic tubes 13 of each stage extend or retract synchronously. It provides rigid support throughout the entire process, eliminates slack and swaying of the wire rope, ensures smooth lifting and lowering, high positioning accuracy, and self-locking safety, thus solving the problems of easy wear, easy breakage, and poor stability of traditional wire rope lifting.

[0043] In embodiment 3, a connecting plate 10 is provided on the outer wall of one end of the multi-stage telescopic mechanism 9, and a radar assembly 11 is provided on the outer wall of one side of the connecting plate 10. The radar assembly 11 includes a horizontal plate 111, a fixing column 112, a frame 113, and a radar head 114. The horizontal plate 111 is fixedly connected to the outer wall of one side of the connecting plate 10 by screws. The symmetrically distributed fixing columns 112 are welded to the outer wall of one side of the horizontal plate 111. The frame 113 is installed through the outer wall of the fixing column 112. The radar head 114 is fixedly connected to the bottom outer wall of the frame 113 by screws.

[0044] Through the above scheme, the connecting plate 10 realizes the rigid connection between the multi-stage telescopic mechanism 9 and the radar component 11, ensuring the synchronous transmission of lifting and flipping movements. The horizontal plate 111, the fixed column 112 and the frame 113 form a stable support frame, providing a reliable mounting base for the radar head 114, ensuring that the radar antenna has a stable attitude and the signal does not deviate during the lifting and flipping process, thus improving the reliability of communication and detection.

[0045] In this embodiment, the radar component 11 is rigidly connected to the multi-stage telescopic mechanism 9, and with the dual functions of flipping and lifting, the signal coverage angle is wider, the operating height is higher, the storage volume is smaller, the structure is highly integrated, the installation is simple, and the protection is good, which meets the all-weather and all-scenario use requirements of the vehicle-mounted mobile platform radar 5G antenna.

[0046] The housing 4 includes a frame 41, a sealing cover 42, and an end sleeve 43. The frame 41 is fixedly connected between two mounting plates 5 by screws. The sealing cover 42 is installed on the top outer wall of the frame 41. The end sleeve 43 is fixedly connected to one side outer wall of the frame 41 by screws, and the sleeve 7 is installed through the inner wall of the end sleeve 43.

[0047] Through the above scheme, the frame 41 provides installation and protection space for the internal drive components, the sealing cover 42 facilitates later maintenance and repair, and the end sleeve 43 is fixed in the position of the sleeve 7 to ensure that the extension and retraction of the multi-stage telescopic mechanism 9 has high coaxiality, smooth movement without eccentricity or jamming, and improves the overall operational stability.

[0048] The first-level telescopic assembly 91, the second-level telescopic assembly 92, the third-level telescopic assembly 93, the fourth-level telescopic assembly 94, and the fifth-level telescopic assembly 95 each include a lead screw 12 and a telescopic tube 13, and two adjacent telescopic tubes 13 are slidably fitted together.

[0049] With the above scheme, each stage is achieved by the cooperation of the lead screw 12 and the telescopic tube 13 to realize synchronous extension and contraction at each stage. The sliding cooperation between adjacent telescopic tubes 13 ensures smooth movement, stable support, and rigid support throughout the entire process. Compared with the traditional steel wire rope structure, it has stronger load-bearing capacity, better wind resistance and stability, and higher safety.

[0050] Both ends of the lead screw 12 are respectively provided with threaded rings 14 and guide heads 15 on their outer walls, and both ends of the telescopic tube 13 are fixedly installed with fixed sleeves 16 and sliding sleeves 17. The threaded rings 14 are installed on the inner wall of the fixed sleeves 16, and the lead screw 12 is threadedly engaged with the adjacent threaded rings 14. The guide heads 15 are slidably engaged with the inner wall of the adjacent lead screw 12. The inner wall of the sliding sleeve 17 is filled with sealing rings 18, and the sealing rings 18 are interference-fitted with the adjacent telescopic tubes 13.

[0051] Through the above scheme, the lead screw 12 and the threaded ring 14 are threaded together to realize the telescopic drive. The guide head 15 slides in the adjacent lead screw 12 to ensure coaxiality and motion accuracy. The fixed sleeve 16 and the sliding sleeve 17 are accurately positioned. The sealing ring 18 achieves dust and water protection, reduces internal wear, adapts to harsh vehicle and outdoor environments, and extends the service life of the device.

[0052] The lead screw 12 inside the first-stage telescopic assembly 91 is fixedly connected to the outer wall of one side of the driven gear 85.

[0053] With the above scheme, the driven gear 85 directly drives the lead screw 12 of the first-stage telescopic component 91 to rotate, and then through the threaded engagement and guide structure, drives all the lead screws 12 of all stages to rotate synchronously, and all the telescopic tubes 13 to extend or retract synchronously, realizing single-power drive five-stage synchronous telescopic movement. The structure is simple, the transmission is efficient, and the failure rate is low.

[0054] The top outer wall of the base plate 1 is welded with symmetrically distributed support supports 19, and the top outer wall of the support supports 19 is provided with an arc-shaped groove, and the sleeve 7 is tightly attached to the inner wall of the arc-shaped groove.

[0055] Through the above scheme, the support 19 provides reliable support for the sleeve 7 and the multi-stage telescopic mechanism 9 in the horizontal storage state, disperses the load, protects the structure, prevents deformation and damage caused by vehicle bumps, and the arc groove fits tightly, providing stable support and good shock absorption.

[0056] A control cabinet 20 is installed on the top outer wall of the base plate 1 between two support arms 19, and the control cabinet 20 is electrically connected to the electric push rod 6 and the radar head 114 via signal lines.

[0057] Through the above solution, the control cabinet 20 achieves automatic control, and can control the electric push rod 6 to flip and the radar head 114 to start and stop with one button, realizing automated operation. It is convenient to operate, responds quickly, and improves the intelligence level and operation efficiency of vehicle use.

[0058] Working principle: The working process of this device is divided into five stages: horizontal storage, synchronous flipping, multi-stage lifting, working operation, and retraction and reset. All mechanisms work together in a stable and reliable manner.

[0059] When the vehicle is in motion, the device is in a horizontally retracted position. The multi-stage telescopic mechanism 9 is completely retracted into the sleeve 7, which is supported by the support 19. The overall center of gravity is low and the space occupied is small.

[0060] When entering the working mode, the control cabinet 20 simultaneously outputs synchronous control signals to the two electric push rods 6. The two electric push rods 6 adopt coaxial and stroke linkage control. Through the electronic control closed loop, the thrust and extension speed are consistent and extend upward synchronously, pushing the mounting plates 5 on both sides and the box 4 to rotate synchronously around the bearing seat 3. This smoothly drives the sleeve 7 and the multi-stage telescopic mechanism 9 to flip upward from the horizontal state until the box 4 and the bottom plate 1 are in a 90° vertical position, completing the flipping action.

[0061] After flipping into place, turn the handle 87. The power is reduced and increased in torque by the reducer 82 and then transmitted to the drive gear 83. The drive gear 83 drives the intermediate wheel 84 to mesh and rotate with the driven gear 85. The driven gear 85 directly drives the lead screw 12 inside the first-stage telescopic component 91 to rotate.

[0062] The lead screw 12 forms a threaded engagement with the threaded ring 14 of the adjacent telescopic tube 13, while the guide head 15 slides with the inner wall of the adjacent lead screw 12. When the first-stage lead screw 12 rotates, it sequentially drives all the lead screws 12 in the second-stage telescopic assembly 92, the third-stage telescopic assembly 93, the fourth-stage telescopic assembly 94, and the fifth-stage telescopic assembly 95 to rotate synchronously. Each stage of the lead screw 12 engages with the corresponding threaded ring 14, pushing each stage of the telescopic tube 13 to extend outward along the sliding sleeve 17 in sequence, achieving five-stage synchronous extension and driving the radar assembly 11 to rise and fall smoothly. When the handle 87 is rotated in the opposite direction, each stage of the lead screw 12 rotates in the opposite direction, and the telescopic tube 13 retracts synchronously, realizing the lifting and lowering adjustment.

[0063] After the work is completed, first turn the handle 87 in the opposite direction to make the multi-stage telescopic mechanism 9 fully retract, then control the two electric push rods 6 to retract synchronously, and the box 4 flips down to restore the horizontal storage state, completing the entire work cycle.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
