Description

Technical Field

[0001] This utility model relates to the field of drone camera protection technology, and in particular to a drone camera protection device. Background Technology

[0002] In fields such as drone aerial photography, surveying, and inspection, the stability and image quality of cameras are crucial. Drones experience vibrations and airflow impacts during flight, and their working environment may also encounter rain, snow, dust, or temperature changes, all of which can damage exposed cameras or affect their normal operation.

[0003] A search revealed a prior art camera protection device for drones (publication number: CN220518590U), comprising a drone body, a protective shell connected to the drone body, a connecting shaft connected to the protective shell, a sealing cover fixedly connected to the connecting shaft, a fixed base slidably connected to the protective shell, several clamping claws connected to the fixed base, a top rod fixedly connected to the fixed base, a drive motor for driving the top rod to slide, and a controller. The protective shell has an opening slot and a sliding port. The position of the opening slot corresponds to the position of the sealing cover, and the shape and size of the opening slot and the sealing cover are adapted to each other. The top rod passes through the sliding port, and the cross-sectional shape of the top rod is adapted to the cross-sectional shape of the sliding port. The sliding direction of the fixed base is parallel to the axial direction of the opening slot. A spring is provided on the connecting shaft. When the spring is in its initial state, the sealing cover covers the opening slot. The controller is electrically connected to the drive motor. The overall structure is complex and not easy to disassemble and assemble quickly. When it is necessary to replace the lens, clean the inside or perform maintenance, the operation is cumbersome. Secondly, it is difficult to balance the airtightness and heat dissipation of the shell. Although a completely sealed shell can prevent dust and water, it is easy to cause internal heat to accumulate, which will affect the life of the camera and even produce water vapor. Furthermore, there is a lack of effective anti-fog measures. In environments with large temperature differences, water vapor is easy to condense inside the shell, which seriously affects the shooting image.

[0004] Therefore, we propose a camera protection device for drones. Utility Model Content

[0005] The present invention mainly solves the technical problem that the above-mentioned protective shell is inconvenient to disassemble and install for the maintenance of camera components, and provides a camera protection device for drones.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a camera protection device for unmanned aerial vehicles, comprising: The first shell and the second shell are horizontally connected and can be used to build a box structure. The top of the first shell is fixedly installed with a flange for assembly. The side walls of the first shell and the second shell are provided with several ventilation slots. A first locking structure is provided between a first housing and a second housing for locking. The first locking structure includes a pawl and a locking block. The pawl is fixedly connected to the second housing and the locking block is fixedly connected to the first housing. The locking block has a slot, and the pawl can be engaged into the slot. The second locking structure is provided on the side wall of the first housing to horizontally limit the box structure formed by the first housing and the second housing.

[0007] In a preferred embodiment of the present invention, the first housing forms an L-shaped plate with a top, the second housing forms an L-shaped plate with a bottom, and a plurality of drawers are fixedly installed on the inner top surface of the first housing, the drawers storing anti-fog bags.

[0008] In a preferred embodiment of the present invention, the side wall of the first housing is provided with an insertion hole, the side wall of the second housing is provided with a protrusion that fits the insertion hole with a gap, the protrusion is inserted into the insertion hole, and a sealing gasket is provided between the first housing and the second housing.

[0009] In a preferred embodiment of this utility model, the claw is formed into a deformable L-shaped rod, and the slot of the locking block cooperates with the claw.

[0010] In a preferred embodiment of this utility model, the second locking structure includes a permanent magnet and a locking frame. The permanent magnet is fixedly installed with the first housing, and the locking frame is vertically mounted above the permanent magnet. The permanent magnet can attract the locking frame, and the locking frame forms a rectangular frame to lock the first housing and the second housing.

[0011] In a preferred embodiment of this utility model, the permanent magnet is L-shaped and is fixedly installed on the outer side wall of the first housing. The locking frame is a rectangular frame, and the box structure formed by the first housing and the second housing is adapted to the locking frame.

[0012] In a preferred embodiment of this utility model, the second locking structure further includes a guide rod, which is fixedly installed at the bottom of the locking frame. A permanent magnet passes through a through hole adapted to the guide rod, and the guide rod is slidably disposed within the through hole.

[0013] This utility model provides a camera protection device for drones. It has the following beneficial effects: 1. The camera protection device for a drone forms a box by horizontally inserting a first shell and a second shell, and combines a first locking structure composed of claws and locking blocks to achieve quick docking and initial locking of the shell. This modular design allows the shell to be easily separated without the aid of tools when it is necessary to inspect or replace the internal camera, which greatly simplifies the maintenance process and improves work efficiency.

[0014] 2. This is a camera protection device for a drone. The device achieves air circulation between the inside and outside of the shell by opening ventilation slots, which not only helps to dissipate heat and prevent the camera from overheating during long-term operation, but also balances the temperature difference between the inside and outside, and suppresses the formation of fog from a physical structure perspective. At the same time, a drawer for storing anti-fog bags is set on the top surface inside the first shell, which further prevents the lens from fogging through active moisture absorption. This passive ventilation + active anti-fog strategy significantly improves the adaptability of the device in different environments and ensures image quality.

[0015] 3. This camera protection device for drones innovatively features a second locking structure composed of a permanent magnet and a locking frame. When the shell is assembled, the lowered locking frame can clamp it and fix it by the attraction force of the permanent magnet. This dual locking mechanism combining mechanical and magnetic forces effectively enhances the overall rigidity and stability of the shell structure, can resist vibration and impact during flight, and provides redundant and reliable protection for the internal camera.

[0018] A camera protection device for drones, such as Figure 1 and Figure 2 As shown, it includes: The first housing 10 and the second housing 11 can be horizontally inserted to form a box structure. The top of the first housing 10 is fixedly installed with a flange 12 for assembly. The flange 12 can be installed by locking it to the drone with bolts. The side walls of the first housing 10 and the second housing 11 are provided with several ventilation slots 13. In this solution, the first housing 10 and the second housing 11 are assembled to form a box structure to protect the camera assembly, which is convenient for disassembly and maintenance. Secondly, the ventilation slots 13 can maintain ventilation inside the box structure, avoid high temperature of the camera assembly, and at the same time, the ventilation method can also keep the temperature inside and outside the box consistent, suppress the formation of fog, and thus ensure the quality of the camera shooting.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a first locking structure is provided between the first housing 10 and the second housing 11 for locking. The first locking structure includes a claw 14 and a locking block 15. The claw 14 is fixedly connected to the second housing 11, and the locking block 15 is fixedly connected to the first housing 10. The locking block 15 has a slot, and the claw 14 can be inserted into the slot. The first housing 10 forms an L-shaped plate with a top, and the second housing 11 forms an L-shaped plate with a bottom. Several drawers 16 are fixedly installed on the inner top surface of the first housing 10. The drawers 16 store anti-fog bags. The side wall of the first housing 10 has an insertion hole, and the side wall of the second housing 11 has a protrusion that fits with the insertion hole. The protrusion is inserted into the insertion hole. A sealing gasket is provided between the first housing 10 and the second housing 11. The claw 14 forms a deformable L-shaped rod, and the slot of the locking block 15 cooperates with the claw 14. To achieve rapid assembly of the first housing 10 and the second housing 11, the second housing 11 is horizontally inserted into the first housing 10, with the protrusion inserted into the corresponding insertion hole. The spring steel claw 14 can be engaged in the L-shaped slot of the locking block 15, thus initially locking the first housing 10 and the second housing 11 and enabling quick disassembly of the first housing 10 and the second housing 11. The anti-fog bag stored in the drawer 16 can suppress the formation of fog and is convenient for replacement in conjunction with the detachable second housing 11.

[0020] like Figure 2 , Figure 4 and Figure 5 As shown, the second locking structure is provided on the side wall of the first housing 10 to horizontally limit the box structure formed by the first housing 10 and the second housing 11. The second locking structure includes a permanent magnet 20 and a locking frame 21. The permanent magnet 20 is fixedly installed with the first housing 10. The locking frame 21 can be raised and lowered above the permanent magnet 20. The permanent magnet 20 can attract the locking frame 21. The locking frame 21 forms a rectangular frame to lock the first housing 10 and the second housing 11. The permanent magnet 20 is L-shaped and is fixedly installed on the outer side wall of the first housing 10. The locking frame 21 is a rectangular frame. The box structure formed by the first housing 10 and the second housing 11 is adapted to the locking frame 21. The second locking structure also includes a guide rod 22. The guide rod 22 is fixedly installed at the bottom of the locking frame 21. The permanent magnet 20 has a through hole adapted to the guide rod 22. The guide rod 22 is slidably installed in the through hole. As a supplementary explanation to the above solution, since the first housing 10 and the second housing 11 are installed on the bottom of the drone, in order to prevent the second housing 11 from falling off, after the second housing 11 is inserted into the first housing 10, the locking frame 21 drives the guide rod 22 to slide down through the through hole. The bottom of the locking frame 21 is equipped with an iron plate, or the locking frame 21 is made entirely of iron material. The locking frame 21 is fixed by adsorption by a permanent magnet 20. The frame-shaped locking frame 21 tightens the first housing 10 and the second housing 11 to keep them in a stable box shape. The strength and stability of the first housing 10 and the second housing 11 after assembly are higher, and the protection effect is better.

[0021] The working principle of this utility model: Housing docking and initial locking: When installing or maintaining the camera, first push the second housing 11 horizontally towards the first housing 10, so that the protrusion on the second housing 11 is inserted into the corresponding hole of the first housing 10, completing the initial positioning and docking. During this process, the L-shaped claw 14 on the second housing 11 will undergo elastic deformation. When it moves to the slot position of the locking block 15 on the first housing, the claw 14 quickly locks into the slot under its own elastic restoring force, realizing the first quick locking. This process is simple to operate and has a clear locking feel.

[0022] Secondary locking and overall reinforcement: After the initial locking is completed, in order to cope with the more severe vibrations and impacts that the UAV may encounter during flight, the rectangular locking frame 21 is pressed down along the guide rod 22 so that it is completely clamped to the outside of the box structure formed by the assembled first shell 10 and second shell 11. When the locking frame 21 moves down to the designated position, the iron part at its bottom (or the locking frame itself) will be firmly attracted by the L-shaped permanent magnet 20 fixed to the side wall of the first shell 10, thereby fixing the locking frame in this position. This frame structure is like a tight band, which applies a strong constraint force to the two shells from the outside, effectively preventing them from loosening in any direction, and greatly improving the stability and reliability of the overall structure.

[0023] Internal environment control mechanism: During the operation of the drone, the camera generates heat. Multiple ventilation slots 13 on the side wall of the shell form a natural convection channel, allowing the internal hot air to rise and be replaced by the external cold air, thereby achieving effective heat dissipation and preventing heat accumulation. At the same time, this air circulation also helps to maintain the balance of temperature and humidity inside and outside the shell, reducing the risk of condensation on the lens due to the internal temperature being higher than the external dew point. In addition, the anti-fog bag (usually containing moisture-absorbing materials such as silica gel desiccant) placed in the drawer 16 on the top surface of the first shell 10 can actively absorb the trace amount of water vapor that penetrates into the shell, keeping the internal environment dry and providing double anti-fog protection for the camera.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
