Technical Field

[0001] This utility model relates to the field of lidar technology, and in particular to a drone radar pod with easy heat dissipation. Background Technology

[0002] Rotating lidar pods are widely used as important sensor mounting devices in fields such as UAV remote sensing mapping, environmental monitoring, and topographic mapping. Currently, mainstream UAV lidar pods typically use motor-driven rotating mechanisms, enabling the radar to achieve all-round perception of the surrounding environment.

[0003] The existing pods suffer from poor internal heat dissipation after radar installation.

[0004] Therefore, a drone radar pod with good heat dissipation is needed. Utility Model Content

[0005] This invention proposes a drone radar pod with easy heat dissipation, which solves the problem of poor internal heat dissipation after radar installation in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat-dissipating UAV radar pod includes an outer shell. A mounting frame is fixedly installed on the top of the outer shell. A motor is fixed to the rear side of the mounting frame. A rotating rod is connected to the output end of the motor. A gear is fixed in the middle of the rotating rod. A rack meshes with the gear below. A first sliding mechanism is connected to the bottom of one end of the rack. A first guide rail is slidably connected to the outer side of the first sliding mechanism. A movable baffle is installed at the bottom of the first sliding mechanism. A second guide rail is provided in front of the first guide rail. A second sliding mechanism is connected to the bottom of the other end of the rack. Limiting frames are fixed to the outer walls of both sides of the outer shell. A protective net is engaged inside the limiting frame.

[0008] Preferably, the bottom two sides of the outer casing are integrally provided with connecting frames, the bottom of the outer casing is installed with a base, and the two ends of the base are vertically penetrated by connecting bolts.

[0009] Preferably, the first sliding mechanism includes a sliding frame, guide wheels are rotatably mounted on both sides of the sliding frame, an upper transmission rod is movably mounted on the top of the sliding frame, and a lower transmission rod is movably connected to the bottom of the sliding frame.

[0010] Preferably, the first sliding mechanism forms a transmission structure through a rack and pinion, and the first sliding mechanism and the second sliding mechanism have the same structure.

[0011] Preferably, the sliding frame forms a sliding structure between the guide wheel and the first guide rail, and the end of the upper transmission rod is rotatably connected to the sliding frame, and the end of the lower transmission rod is rotatably connected to the sliding frame.

[0012] Preferably, a second sliding mechanism is slidably installed inside the second guide rail, and the bottom of the second sliding mechanism is connected to the top of the movable baffle.

[0013] Preferably, the base is detachable from the connecting frame via connecting bolts, and the connecting bolts are symmetrically arranged about the central axis of the base.

[0014] This invention proposes a heat-dissipating UAV radar pod. Compared with the prior art, the advantages of this invention are:

[0015] 1. By setting gears, the control motor can drive the rotating rod to rotate at a constant speed during use, and through meshing transmission, the lower rack performs forward and backward translational operation. The bottom ends of the rack are respectively connected to a first sliding mechanism and a second sliding mechanism. These sliding mechanisms, with identical structures, are connected to the rack, ensuring that the rack can synchronously control the bottom sliding mechanism and further drive the top of the lower movable baffle to translate along the first and second guide rails. This allows for flexible control of the opening and closing of the movable baffle, facilitating the opening of the movable baffle at appropriate times to improve internal heat dissipation. When the rack drives the sliding frame along the first guide rail via the upper transmission rod, it can steadily... The sliding mechanism ensures overall stability during sliding. Simultaneously, the ends of both the upper and lower transmission rods are rotatably connected to the sliding frame. When the rack and pinion move parallel to the movable baffle, rotation ensures the sliding frame automatically adjusts according to changes in the first guide rail. This allows the sliding frame to automatically adapt to the angled section at the front end of the first guide rail. At this time, the sliding frame automatically changes its sliding angle while stably translating the movable baffle, ensuring the movable baffle smoothly closes outwards until flush with the outer wall of the casing. When opening, it can also retract inwards a short distance to allow the movable baffle to be retracted to the rear of the inner wall of the casing for opening control. The operation is flexible and convenient, facilitating opening and closing control on both sides of the equipment.

[0016] 2. By setting up a protective net, the protective net is inserted horizontally into the middle of the limiting frame for locking and fixing during use. The inner side of the limiting frame is made of rubber, which can directly limit and fix the protective net, ensuring that the protective net is stably locked between the limiting frames. The protective net can be flexibly added as needed to ensure that it provides shielding and protection for the internal equipment without affecting the ventilation effect. It improves heat dissipation and provides better protection for the internal parts. The bottom base is used to install and support the internal radar equipment, and is stably connected and fixed to the connecting frame through the connecting bolts on both sides, ensuring that the equipment can be stably connected, fixed, disassembled and maintained, and facilitating radar installation and fixed support.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see Figure 1-5This utility model provides a technical solution: an easily heat-dissipating UAV radar pod, including a shell 1, a fixing frame 2 fixedly installed on the top of the shell 1, a motor 3 fixedly installed on the rear side of the fixing frame 2, a rotating rod 4 connected to the output end of the motor 3, a gear 5 fixed in the middle of the rotating rod 4, a rack 6 meshing below the gear 5, a first sliding mechanism 7 connected to the bottom of one end of the rack 6, a first guide rail 8 slidably connected to the outer side of the first sliding mechanism 7, a movable baffle 9 installed at the bottom of the first sliding mechanism 7, a second guide rail 10 provided on the front side of the first guide rail 8, a second sliding mechanism 11 connected to the bottom of the other end of the rack 6, and limit frames 12 fixed to the outer walls of both sides of the shell 1, with a protective net 13 engaged inside the limit frame 12.

[0025] Furthermore, the bottom sides of the outer casing 1 are integrally provided with connecting brackets 14, and the bottom of the outer casing 1 is equipped with a base 15, with connecting bolts 16 vertically penetrating both ends of the base 15.

[0026] Furthermore, the first sliding mechanism 7 includes a sliding frame 701, guide wheels 702 are rotatably mounted on both sides of the sliding frame 701, an upper transmission rod 703 is movably mounted on the top of the sliding frame 701, and a lower transmission rod 704 is movably connected to the bottom of the sliding frame 701.

[0027] Furthermore, the first sliding mechanism 7 forms a transmission structure between the rack 6 and the gear 5, and the first sliding mechanism 7 and the second sliding mechanism 11 have the same structure. The rack 6 can synchronously control the bottom sliding mechanism and further drive the top of the lower movable baffle 9 to perform translation operation along the first guide rail 8 and the second guide rail 10, flexibly control the opening and closing, and ensure that the equipment can perform the opening and closing adjustment operation of the movable baffle 9.

[0028] Furthermore, the sliding frame 701 forms a sliding structure with the first guide rail 8 through the guide wheel 702, and the end of the upper transmission rod 703 is rotatably connected to the sliding frame 701, and the end of the lower transmission rod 704 is rotatably connected to the sliding frame 701. The sliding frame 701 can automatically adapt to the bend section at the front end of the first guide rail 8. At this time, the sliding frame 701 can automatically change the sliding angle and stably translate the movable baffle 9, ensuring that the movable baffle 9 can smoothly close outward to be flush with the outer wall of the outer shell 1. When opening, it can also retract inward a bit so that the movable baffle 9 can be retracted to the rear side of the inner wall of the outer shell 1 for opening control. The operation is flexible and convenient.

[0029] Furthermore, a second sliding mechanism 11 is slidably installed inside the second guide rail 10, and the bottom of the second sliding mechanism 11 is connected to the top of the movable baffle 9. The bottom ends of the rack 6 are respectively connected to the first sliding mechanism 7 and the second sliding mechanism 11. The rack 6 is connected to the first sliding mechanism 7 and the second sliding mechanism 11 through the sliding mechanism with the same structure, so that the rack 6 can synchronously control the bottom sliding mechanism.

[0030] Furthermore, the base 15 forms a detachable structure with the connecting bracket 14 through the connecting bolt 16, and the connecting bolt 16 is symmetrically arranged about the central axis of the base 15. The bottom base 15 is used to install and support the internal radar equipment, and is stably connected and fixed with the connecting bracket 14 through the connecting bolt 16 on both sides, so as to ensure that the equipment can be stably connected, fixed and disassembled for maintenance, and facilitate the installation and fixed support of the radar.

[0031] Working principle: First, during use, the control motor 3 drives the rotating rod 4 to rotate at a constant speed, and through meshing transmission, the lower rack 6 performs forward and backward translational operations. The bottom ends of the rack 6 are respectively connected to the first sliding mechanism 7 and the second sliding mechanism 11, which are connected to the rack 6 through identical sliding mechanisms. This ensures that the rack 6 can synchronously control the bottom sliding mechanism and further drive the top of the lower movable baffle 9 to perform translational operations along the first guide rail 8 and the second guide rail 10. This allows for flexible control of the opening and closing of the movable baffle 9, facilitating the opening of the movable baffle 9 at appropriate times to improve internal heat dissipation. When the rack 6 drives the sliding frame 701 along the first guide rail 8 via the upper transmission rod 703, it can stably move... The sliding mechanism ensures overall stability. Simultaneously, the ends of the upper transmission rod 703 and lower transmission rod 704 are rotatably connected to the sliding frame 701. When the overall rack 6 and movable baffle 9 move parallel to each other, the sliding frame 701 automatically adjusts according to the changes in the first guide rail 8, allowing it to automatically adapt to the angled section at the front end of the first guide rail 8. At this time, the sliding frame 701 automatically changes its sliding angle while stably translating the movable baffle 9, ensuring that the movable baffle 9 can smoothly close outwards to be flush with the outer wall of the outer casing 1. When opening, it can also retract inwards a section to allow the movable baffle 9 to be retracted to the rear of the inner wall of the outer casing 1 for opening control. The operation is flexible and convenient, facilitating opening and closing control on both sides of the equipment.

[0032] Next, during use, the protective net 13 is inserted horizontally into the middle of the limiting frame 12 for locking and fixing. The inner side of the limiting frame 12 is made of rubber, which can directly limit and fix the protective net 13, ensuring that the protective net 13 is stably locked between the limiting frames 12. The protective net 13 can be flexibly added as needed to ensure that it provides shielding and protection for the internal equipment without affecting the ventilation effect. It improves heat dissipation and provides better protection for the internal parts. The bottom base 15 is used to install and support the internal radar equipment, and is stably connected and fixed to the connecting frame 14 through the connecting bolts 16 on both sides, ensuring that the equipment can be stably connected, fixed, disassembled and repaired, and facilitating the installation and fixing of the radar.
