Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and specifically relates to a waterproof structure for UAVs. Background Technology

[0002] With the rapid development of drone technology, drones are widely used in fields such as agricultural monitoring, logistics transportation, emergency rescue, and outdoor surveying, often requiring operation in humid, rainy, or water-filled environments. However, the problem of moisture penetration in complex environments seriously threatens the safety of internal electronic components of drones, especially the connection between the battery pack and the casing, which is prone to water ingress, leading to short circuits or malfunctions.

[0003] Existing drone waterproofing technologies mostly employ simple sealing rings or adhesive layers to seal interfaces, such as placing rubber gaskets at the battery mounting area to achieve static sealing. Traditional sealing structures are prone to wear during frequent battery removal and installation, leading to seal failure; furthermore, the lack of an active drainage structure inside the fuselage means that even small amounts of water cannot be drained in time, and long-term accumulation can still corrode electronic components. In view of this, a waterproof structure for drones was designed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a waterproof structure for drones, aiming to solve to some extent the technical problems in the prior art where the sealing structure of drones is easily worn during frequent battery disassembly and assembly, leading to sealing failure; and the lack of an active drainage structure inside the fuselage, so that when a small amount of water seeps in, it cannot be discharged in time, and long-term accumulation will still corrode electronic components.

[0005] The technical solution of this utility model is: a waterproof structure for a drone, including a shell and a battery assembly, wherein the top of the shell is provided with a mounting groove for fixing the battery assembly;

[0006] The inner bottom wall of the mounting groove is provided with an interface groove, and a silicone pad is adhered in the interface groove. The silicone pad is tightly fitted with the battery shell of the battery assembly to form a sealed interface.

[0007] The rear of the housing is provided with at least two drainage grooves, which penetrate the outer wall of the housing and are used to drain water accumulated in the mounting groove to the outside of the housing.

[0008] As a preferred embodiment of the waterproof structure of the UAV described in this utility model, the mounting groove has grooves on both sides of its inner wall, and a mounting bracket located on the casing is fixed in the groove.

[0009] As a preferred embodiment of the waterproof structure of the UAV described in this utility model, the battery assembly has claws on both sides of the battery shell, and the claws are elastically engaged with the mounting base of the shell to form a detachable waterproof locking structure.

[0010] As a preferred embodiment of the waterproof structure of the UAV described in this utility model, the claws are symmetrically distributed on both sides of the battery shell, and the ends of the claws are provided with barbs, which are interference-fitted with the limiting groove of the card seat.

[0011] As a preferred embodiment of the waterproof structure of the UAV described in this utility model, the drainage channel has a U-shaped cross-section, an open top, and the bottom of the drainage channel is flush with the bottom of the mounting groove.

[0012] As a preferred embodiment of the waterproof structure of the UAV described in this utility model, a support pad is adhered to the inner bottom wall of the mounting groove.

[0013] As a preferred embodiment of the waterproof structure of the drone described in this utility model, the inner wall of the mounting groove is provided with a raised strip, which extends longitudinally along the mounting groove and abuts against the outer surface of the battery shell.

[0014] As a preferred embodiment of the waterproof structure of the UAV described in this utility model, the inner walls of the mounting groove and the drainage groove are coated with a hydrophobic coating.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0016] This application incorporates a silicone pad bonded inside the interface slot, effectively sealing the connection between the battery assembly and the casing.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1-4 A waterproof structure for a drone includes a housing 100 and a battery assembly 200. The top of the housing 100 has a mounting groove 110 for fixing the battery assembly 200. The inner bottom wall of the mounting groove 110 has an interface groove 130, and a silicone pad 140 is adhered to the interface groove 130. The silicone pad 140 is adhered to the housing 100 by waterproof double-sided adhesive. The silicone pad 140 and the battery shell 210 of the battery assembly 200 are tightly fitted to form a sealed interface. The silicone pad 140 adhered to the interface groove 130 can utilize the elasticity and flexibility of silicone material to form a seamless sealed interface with the surface of the battery shell 210. This design effectively isolates external moisture from seeping into the interior of the drone from the connection between the battery assembly 200 and the housing 100, and is suitable for the operation needs of drones in humid, rainy or wading environments.

[0026] The rear of the housing 100 is provided with at least two drainage channels 150, which penetrate the outer wall of the housing 100 and are used to drain water accumulated in the mounting slot 110 to the outside of the housing 100. The drainage channels 150 can quickly guide water that has seeped into the mounting slot 110 to the outside of the housing, preventing water from stagnating and corroding the internal electronic components.

[0027] The inner wall of the mounting slot 110 has grooves 160 on both sides, and a mounting bracket 170 located on the housing 100 is fixed in the groove 160. The battery housing 210 of the battery assembly 200 has claws 220 on both sides, which elastically engage with the mounting brackets 170 of the housing 100 to form a detachable, waterproof locking structure. The symmetrically distributed claws 220 on both sides of the battery housing 210 and the mounting brackets 170 of the housing 100 form a locking structure through elastic engagement, enabling detachable installation of the battery assembly 200 and constraining its installation position to prevent displacement due to vibration during flight.

[0028] The claws 220 are symmetrically distributed on both sides of the battery housing 210. The ends of the claws 220 are provided with barbs. The barbs are interference-fitted with the limiting groove of the card holder 170, which improves the stability of the battery assembly 200 installation.

[0029] The drainage channel 150 has a U-shaped cross-section, with an open top and a bottom flush with the bottom of the mounting groove 110. This allows water accumulated in the mounting groove 110 to flow quickly to the outside of the casing, preventing moisture retention and corrosion of internal electronic components. The U-shaped cross-section further enhances drainage efficiency and reduces the occurrence of blockages.

[0030] A support pad 120 is bonded to the inner bottom wall of the mounting slot 110, providing a stable support surface for the battery assembly 200. The flexible material of the support pad 120 can absorb the vibration energy generated by airflow or landing impact during flight, reducing wear caused by hard contact between the battery assembly 200 and the housing 100.

[0031] The inner wall of the mounting groove 110 is provided with a raised strip 180, which extends longitudinally along the mounting groove 110 and abuts against the outer surface of the battery case 210. The slight elastic deformation of the raised strip 180 can compensate for the assembly tolerance of the battery case 210, ensuring the stability of the battery assembly 200 installation.

[0032] The inner walls of the mounting groove 110 and the drainage groove 150 are coated with a hydrophobic coating. The hydrophobic coating reduces the surface energy of the inner wall, making it difficult for water to adhere and improving the flow efficiency of the drainage groove 150.

[0033] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
