Those skilled in the art can reasonably determine the specific meaning of the above terms in this specification in conjunction with the specific content of the technical solution.

[0034] Unmanned Aerial Vehicles (UAVs), as aircraft controlled by radio remote control or autonomous programs, can be applied to fields such as daily video shooting, sports photography, agricultural plant protection, and geographic surveying. With technological advancements, UAVs are gradually developing towards multi-functionality and intelligence, and their operational scenarios are expanding from conventional land environments to water surfaces, seas, and rainy climates, which places higher demands on the environmental adaptability of UAVs.

[0035] The main technical challenge currently facing drones taking off from water or in marine environments lies in the waterproofing of their power systems and electronic equipment. The high salt spray corrosion, wave impact, and the risk of instantaneous immersion during takeoff and landing in the marine environment necessitate reliable, sealed structures for drones. In some application scenarios, drones must ensure that their motors, flight control systems, and gimbal systems continue to function normally even under splashes or brief water immersion. Furthermore, the need for continuous operation in rainy environments also compels drones to possess splash-proof and water-proof capabilities to prevent rainwater intrusion that could cause short circuits or sensor malfunctions.

[0036] Based on this, one or more embodiments of this specification provide a waterproof drone, wherein the lower shell assembly and the upper shell assembly of the main unit are sealed by potting, and a sealing surface and a battery sealing component are arranged between the battery and the battery compartment, which has good waterproof performance.

Figure 2 This is a top view schematic diagram of a waterproof drone according to some embodiments shown in this specification. Figure 3This is a bottom view schematic diagram of a waterproof drone according to some embodiments shown in this specification. Figure 4 This is a front view schematic diagram of a waterproof drone according to some embodiments of this specification. Figure 5 This is a side view schematic diagram of a waterproof drone according to some embodiments shown in this specification. Figure 6 This is an exploded schematic diagram of a waterproof drone according to some embodiments of this specification. See also Figures 1 to 6 As shown, in one or more embodiments of this specification, a waterproof drone may include: a main unit 1, a rotor assembly 2 electrically connected to the main unit 1, and a frame 3 surrounding the main unit 1. In some embodiments, the rotor assembly 2 includes blades and a motor for driving the blades to rotate. In some embodiments, see [link to documentation]. Figure 7 As shown, the main unit 1 includes a lower shell assembly 11, an upper shell assembly 12, and a battery 13. The lower shell assembly 11 and the upper shell assembly 12 are connected. One of the lower shell assembly 11 and the upper shell assembly 12 has a main unit sealant groove 100, which is filled with main unit sealant (e.g., Kraft glue). In some embodiments, the lower shell assembly 11 has a receiving space for accommodating electrical components such as circuit boards. In some embodiments, the main unit sealant groove 100 surrounds the receiving space. In some embodiments, the lower shell assembly 11 and the upper shell assembly 12 are bonded together by main unit sealant. In some embodiments, the lower shell assembly 11 and the upper shell assembly 12 may further be fixedly connected by one or more fasteners.

[0038] In some embodiments, during assembly, host sealant is injected into the host sealant groove 100, the upper shell assembly 12 is assembled onto the lower shell assembly 11, so that the upper shell assembly 12 and the lower shell assembly 11 fit together in place, and pressure is applied to allow the host sealant to cure naturally, thereby achieving a waterproof seal between the lower shell assembly 11 and the upper shell assembly 12.

[0039] In some embodiments, the upper housing assembly 12 includes a battery compartment 121 for accommodating the battery 13, and the battery compartment 121 includes a first battery sealing surface 1211.

The lower battery structure 131 is disposed inside the battery compartment 121, and the size of the upper battery structure 132 is larger than the size of the lower battery structure 131. At least a portion of the upper battery structure 132 forms a second battery sealing surface 1321.

[0040] In some embodiments, the first battery sealing surface 1211 and the second battery sealing surface 1321 mate. In some embodiments, the first battery sealing surface 1211 and the second battery sealing surface 1321 abut against each other to form a seal. In some embodiments, the first battery sealing surface 1211 and the second battery sealing surface 1321 may be parallel to or substantially parallel to the bottom surface or horizontal plane of the drone, so that the seam of the first battery sealing surface 1211 and the second battery sealing surface 1321 is located on the side of the main unit 1 to reduce rainwater infiltration.

[0041] In some embodiments, a battery sealing member 14 is provided between the first battery sealing surface 1211 and the second battery sealing surface 1321. In some embodiments, the battery sealing member 14 may surround the lower battery structure 131 of the battery 13. In some embodiments, the battery sealing member 14 may be an annular sealing ring, such as an annular silicone sealing ring.

[0042] In one or more embodiments of this specification, the waterproof drone may further include a gimbal 4 connected to the main unit 1 or the frame 3. In some embodiments, the gimbal 4 may rotate relative to the main unit 1 or relative to the frame 3. In some embodiments, the gimbal 4 may be used to actively isolate various harmful movements generated by the waterproof drone, providing a stable physical platform for the mounted imaging device. In some embodiments, the gimbal 4 may ensure that the mounted imaging device is always pointed to and stably maintained in the target direction.

[0043] In some embodiments, the imaging device mounted on the gimbal 4 may include one or more of a camera, an infrared thermal imager, a lidar, and a multispectral sensor. In some embodiments, harmful motions actively isolated by the gimbal 4 may include high-frequency micro-vibrations caused by motor rotation, propeller aerodynamic turbulence, and structural resonance of the airframe, as well as low-frequency large-amplitude angular swaying caused by changes in the UAV's flight attitude (such as pitch, roll, and yaw). In some embodiments, the gimbal 4 also allows the operator to actively control the angle of the mounted imaging device.

[0044] In some embodiments, see Figure 8 As shown, the gimbal 4 may include: a gimbal housing 41, a gimbal heat sink 42, and a first gimbal sealing member 43 disposed between the gimbal housing 41 and the gimbal heat sink 42. In some embodiments, the gimbal heat sink 42 includes a substrate and one or more heat dissipation fins disposed on the substrate. In some embodiments, see [link to relevant documentation]. Figure 9 , Figure 10As shown, the gimbal heat sink 42 includes a first annular structure 421 and a second annular structure 422 surrounding the first annular structure 421, with a heat sink sealing groove formed between the first annular structure 421 and the second annular structure 422. In some embodiments, the gimbal housing 41 includes a gimbal housing sealing mating portion 411, which is disposed within the heat sink sealing groove. In some embodiments, a first gimbal sealing member 43 is disposed within the heat sink sealing groove. In some embodiments, the gimbal housing sealing mating portion 411 can abut against the first gimbal sealing member 43 to form a seal. In some embodiments, the first gimbal sealing member 43 can be an annular sealing ring, such as an annular silicone sealing ring.

[0045] In some embodiments, the first gimbal sealing member 43 includes a sidewall sealing surface 431 that conforms to the sidewall of the heat sink sealing groove and a bottom sealing surface 432 that conforms to the bottom of the heat sink sealing groove. In some embodiments, the sidewall sealing surface 431 may be annular. In some embodiments, the bottom sealing surface 432 may be annular.

[0046] In some embodiments, see Figure 9 , Figure 10 As shown, the first gimbal sealing member 43 includes a first gimbal sealing member fixing portion 430, which can cover the first annular structure 421 to fix the first gimbal sealing member 43 to the gimbal heat sink 42. In some embodiments, the cross-section of the first gimbal sealing member fixing portion 430 can be U-shaped. In some embodiments, one side of the first gimbal sealing member fixing portion 430 (e.g.) Figure 10 The right side of the gimbal housing sealing mating part 411 provides a sidewall sealing surface 431. In some embodiments, the side of the gimbal housing sealing mating part 411 (e.g., the inner side of the gimbal housing sealing mating part 411, i.e., the right side of the gimbal housing sealing mating part 411) provides a sidewall sealing surface 431. Figure 10 The left side of the middle can be fitted to the side wall sealing surface 431.

[0047] In some embodiments, see Figure 9 , Figure 10 As shown, one side of the first gimbal sealing member fixing portion 430 extends outward to provide a bottom sealing surface 432. In some embodiments, the end face of the gimbal housing sealing mating portion 411 (e.g., Figure 10 The upper surface of the middle part can be fitted to the bottom sealing surface 432.

[0048] In some embodiments, one or more sealing protrusions 433 are formed on the sidewall sealing surface 431. In some embodiments, the gimbal housing sealing mating part 411 can fit against the sealing protrusion 433. In some embodiments, the gimbal housing sealing mating part 411 can deform the sealing protrusion 433 to achieve an interference fit and enhance the sealing effect.

[0049] In some embodiments, the sidewall sealing surface 431 extends outward (e.g. towards...). Figure 10 One or more sealing protrusions 433 are formed by extending to the right side of the sealing surface 431. In some embodiments, the sealing protrusions 433 may be annular. In some embodiments, a plurality of annular sealing protrusions 433 may be arranged sequentially along the sidewall sealing surface 431. For example, Figure 10 The image shows two annular sealing protrusions 433. In other embodiments, the sealing protrusions 433 may be dot-shaped, with a plurality of dot-shaped sealing protrusions 433 arranged in an annular array relative to the sidewall sealing surface 431.

[0050] In some embodiments, the plane containing the sidewall sealing surface 431 may intersect the plane containing the bottom sealing surface 432. In some embodiments, the plane containing the sidewall sealing surface 431 may be perpendicular to the plane containing the bottom sealing surface 432. In some embodiments, the sidewall sealing surface 431 and the bottom sealing surface 432 provide multiple seals. Specifically, the sidewall sealing surface 431 provides a seal at the connection between the gimbal housing 41 and the gimbal heat sink 42 (e.g., ...). Figure 10 The seal is located in the left-right direction (this direction is the possible water ingress direction of the gimbal 4). The angle formed by the bottom sealing surface 432 and the side wall sealing surface 431 forms a labyrinth seal.

[0051] In one or more embodiments of this specification, a bearing 442 may be arranged at one end of the gimbal 4 to adapt it for rotation, and a motor 47 may be arranged at the other end of the gimbal 4 to provide power for its rotation.
