Description

Technical Field

[0001] The utility model belongs to the technical field of installation structures, and particularly relates to an inertial navigation installation structure. Background Technique

[0002] The inertial navigation system is an ideal navigation system. In the field of intelligent UAV navigation, the research on the inertial navigation system has been widely concerned for many years, and a large number of theoretical research results have been applied in practice. The inertial navigation system greatly enhances the autonomy, flexibility and adaptability of intelligent UAVs, enabling them to efficiently execute tasks in various complex and challenging environments.

[0003] The inertial navigation system needs to be installed on the intelligent UAV through a corresponding installation structure. At present, there are some installation structures for the inertial navigation system of intelligent UAVs on the market. For example, a Chinese patent discloses an inertial navigation installation structure for a UAV with a publication number of CN220809836U. This installation structure can realize the fixation of inertial navigation bodies of different specifications, but there are some defects and deficiencies to be improved: (1) Due to the structural design, some existing inertial navigation installation structures often lack an independent power supply module. After the inertial navigation system is installed on the intelligent UAV, it needs to rely on the power supply of the UAV to supply power to the inertial navigation system, which will increase the power consumption of the UAV, affect the endurance, and at the same time cause fluctuations in the stability of the UAV power supply, thus affecting the normal operation of the UAV and the inertial navigation system; (2) Some existing inertial navigation installation structures lack effective heat dissipation measures. When the inertial navigation system operates for a long time or the UAV flies in a high-temperature environment, the heat generated by it is difficult to be discharged in time, which easily leads to failures of electronic components in the inertial navigation system due to overheating. Therefore, in view of the above problems, it is of great significance to provide an inertial navigation installation structure according to the utility model. Content of the Utility Model

[0004] The utility model provides an inertial navigation installation structure, which can realize the independent power supply of the inertial navigation system through the power supply module without consuming the power of the UAV itself, thus effectively reducing the power consumption of the UAV and prolonging its endurance time. And through the independent power supply module, the power supply of the inertial navigation system and the UAV can be made more stable, thus ensuring the normal operation of the inertial navigation system and the UAV; through the heat dissipation member, the heat generated by the inertial navigation system and the power supply module can be fully absorbed and quickly diffused to the outside of the installation shell through the heat dissipation port, thus greatly improving the heat dissipation performance of the installation structure and effectively avoiding failures of electronic components in the inertial navigation system and the power supply module due to overheating. In summary, the problems in the background technique are solved.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0030] In the description of the present utility model, it should be understood that the terms "relative", "one end", "inside", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc. indicating orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0031] Please refer to Figures 1-9 As shown, an inertial navigation installation structure of the present utility model includes a mounting shell 1. The two top ends of the mounting shell 1 are L-shaped and are provided with a plurality of mounting holes 2. Screws can be inserted into the mounting holes 2, and the mounting shell 1 can be fixedly installed on the unmanned aerial vehicle through the screws. Fixed blocks 3 are fixedly connected to the inner walls of the two bottom ends of the mounting shell 1. A support plate 4 is arranged above the fixed blocks 3. The support plate 4 is fixedly connected to the inner wall of the mounting shell 1, and a plurality of heat conduction holes 5 are formed on its surface. An inertial navigation body 6 is installed on the support plate 4. The inertial navigation body 6 is a prior art, and an inertial measurement unit, a data processing unit, an interface module, etc. (not shown in the figure) are integrated inside it. These components are all existing products that can be directly purchased on the market, and their specific structures will not be elaborated. A power supply module is arranged at the bottom of the mounting shell 1, and a plurality of heat dissipation ports 7 are formed on the two side walls thereof. Heat dissipation components are arranged on both sides of the mounting shell 1;

[0032] The power supply module includes a bottom cover 8. The bottom cover 8 is rectangular, and its length and width are respectively equal to the inner wall length and width of the installation shell 1. A power supply 9 is installed on the top of the bottom cover 8. Threaded holes 10 are provided at the four corners of the bottom cover 8, and bolts 11 that are matched with the threaded holes 10 are threadedly connected therein. When the inertial navigation body 6 and the power supply module are both installed in the installation shell 1, the power supply 9 can be electrically connected to the inertial navigation body 6 through a power supply wire. At this time, the inertial navigation body 6 can be independently powered by the power supply 9 without consuming the power of the drone itself, thereby effectively reducing the power consumption of the drone and extending its endurance time. Moreover, the independent power supply module can make the power supply of the inertial navigation body 6 and the drone more stable, thus ensuring the normal operation of the inertial navigation system and the drone;

[0033] The heat dissipation component includes a heat dissipation frame 12. The heat dissipation frame 12 is L-shaped, and one side of it is fixedly connected to the outer wall of the installation shell 1. A plurality of heat conduction fins 13 are fixedly connected to the side wall of the heat dissipation frame 12. The heat conduction fins 13 pass through the heat dissipation port 7 and extend into the installation shell 1. The heat conduction fins 13 are made of metal materials with strong heat conduction performance such as copper sheets. When the inertial navigation body 6 operates for a long time or the drone flies in a high-temperature environment, the heat conduction fins 13 can fully absorb the heat generated by the inertial navigation body 6 and the power supply 9 and quickly diffuse it to the outside of the installation shell 1 through the heat dissipation port 7, thereby greatly improving the heat dissipation performance of the installation structure and effectively preventing the electronic components in the inertial navigation body 6 and the power supply 9 from malfunctioning due to overheating.

[0034] Among them, a plurality of bumps 14 are fixedly connected to both sides of the inertial navigation body 6. Positioning holes 15 are provided on the surface of the bumps 14. A plurality of positioning columns 16 are fixedly connected to the top of the support plate 4. External threads are engraved on the column body of the positioning columns 16, and nuts 17 that are matched with the positioning columns 16 are threadedly connected thereto. The number of the positioning columns 16 is the same as that of the positioning holes 15, and their diameters are equal. The center of each positioning column 16 corresponds to the center of each positioning hole 15 one by one. When the inertial navigation body 6 is placed on the support plate 4, each positioning column 16 can be aligned with and pass through the corresponding positioning hole 15. At this time, when the nuts 17 are threadedly connected to each positioning column 16 and tightened, the inertial navigation body 6 can be fixed through the mutual cooperation among the positioning columns 16, the positioning holes 15, and the nuts 17 to prevent it from loosening after being installed on the drone. By unscrewing the nuts 17, the inertial navigation body 6 can be removed from the support plate 4 for regular maintenance or replacement.

[0035] Among them, a plurality of threaded grooves 18 adapted to the bolts 11 are provided on the bottom surface of the fixed block 3. The number of the threaded grooves 18 is the same as that of the threaded holes 10, and the diameters are equal. The centers of each threaded groove 18 and each threaded hole 10 correspond to each other one by one. When the bottom cover 8 is attached to the bottom of the mounting case 1, the bolts 11 in each threaded hole 10 can be screwed into the corresponding threaded grooves 18. At this time, the bottom cover 8 together with the power supply 9 can be fixed through the mutual cooperation between the bolts 11 and the threaded grooves 18. By unscrewing the bolts 11, the power supply 9 can be taken out of the mounting case 1, so as to be charged in time or directly replaced after the power supply 9 is used up.

[0036] Among them, the heat dissipation openings 7 are rectangular and are linearly distributed at equal intervals along the width direction of the mounting case 1. The number of the heat conducting fins 13 is the same as that of the heat dissipation openings 7, and the centers of each heat conducting fin 13 and each heat dissipation opening 7 correspond to each other one by one. Each heat conducting fin 13 can pass through the corresponding heat dissipation opening 7 and extend into the mounting case 1. Through the plurality of heat conducting fins 13 and the heat dissipation openings 7, the heat absorption and heat conduction ranges of the heat dissipation components can be expanded, so as to accelerate the discharge of heat, thereby further improving the heat dissipation efficiency and effect.

[0037] Among them, a pair of wire openings 19 are provided on the top of the support plate 4. The wire openings 19 are rectangular and are respectively located on the front side and the rear side of the inertial navigation body 6. A pair of wiring boards 20 are fixedly connected to the top of the support plate 4. The wiring boards 20 are located between the wire openings 19 and the inertial navigation body 6, and a plurality of wiring grooves 21 are provided on the top of the wiring boards 20. The wiring grooves 21 are U-shaped and are linearly distributed at equal intervals along the length direction of the wiring boards 20. Each power supply line on the power supply 9 can pass through the wire opening 19 and be connected to each interface on the inertial navigation body 6. When the number of power supply lines is large, each power supply line can pass through and fit in the corresponding wiring groove 21 respectively. At this time, each power supply line can be separated and fixed through the wiring groove 21, so that the wiring of the power supply lines is more tidy and reasonable, thereby effectively avoiding the entanglement of the power supply lines after messy wiring.

[0038] The circuits, electronic components and chip modules involved in the present utility model are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve the improvement of software and methods either.

[0039] The standard parts used in the application documents can be purchased from the market. All the components in the application documents can be customized according to the descriptions in the specification and the drawings.

The machines, parts and equipment all adopt conventional models in the prior art. The electrical components in this article are all electrically connected to the external main controller and 220V mains, and the main controller can be a conventional known device such as an LED lamp body for control.

[0040] The working principle of the present utility model is as follows:

[0041] When the present utility model is in use, the inertial navigation body 6 and the power supply module can be respectively installed on the pallet 4 inside the installation shell 1 and the bottom of the installation shell 1, and then the installation shell 1 is fixedly installed on the unmanned aerial vehicle by screws, so as to realize the application of the inertial navigation body 6 on the unmanned aerial vehicle. The power supply 9 in the power supply module can be electrically connected to the inertial navigation body 6 through a power supply line. At this time, the inertial navigation body 6 can be independently powered by the power supply 9 without consuming the power of the unmanned aerial vehicle itself, thereby effectively reducing the power consumption of the unmanned aerial vehicle and extending its endurance time. Moreover, the independent power supply module can make the power supply of the inertial navigation body 6 and the unmanned aerial vehicle more stable, thus ensuring the normal operation of the inertial navigation system and the unmanned aerial vehicle. The power supply 9 can be taken out of the installation shell 1 by unscrewing the bolt 11, so as to charge or directly replace it in time after the power supply 9 is used up. The inertial navigation body 6 can be removed from the pallet 4 by unscrewing the nut 17, so as to perform regular maintenance or replacement on the inertial navigation body 6. When the inertial navigation body 6 operates for a long time or the unmanned aerial vehicle flies in a high-temperature environment, the heat dissipation fin 13 can fully absorb the heat generated by the inertial navigation body 6 and the power supply 9, and quickly diffuse it to the outside of the installation shell 1 through the heat dissipation port 7, thereby greatly improving the heat dissipation performance of the installation structure and effectively avoiding the failure of the electronic components in the inertial navigation body 6 and the power supply 9 due to overheating.
