[0027] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] See also Figure 1 and Figure 2 The present application provides a drone 100, which includes a fuselage 10, wings 20, a power device 30 and a battery device 40. The wings 20 and the power device 30 are both arranged on the fuselage 10, and the wings 20 and the power device 30 provide lift for the fuselage 10 so that the drone 100 can perform flight missions. The fuselage 10 is provided with a battery compartment 11 and a battery interface 12, and the battery device 40 is arranged in the battery compartment 11 and connected to the battery interface 12, and the battery device 40 is configured to provide electrical energy to the power device 30 and the electrical components inside the fuselage 10. The battery compartment 11 includes a relatively arranged compartment opening 11a and a compartment bottom 11b, wherein the compartment opening 11a is upwardly connected to the outside world, so that the battery device 40 can be placed in the battery compartment 11 from above the battery compartment 11, and the compartment bottom 11b has a supporting function for the battery device 40. The battery interface 12 is located at the upper part of the battery compartment 11. As Figure 4 As shown, that is, along the direction from the bottom 11b of the battery compartment 11 toward the compartment opening 11a, the battery interface 12 is located between the compartment opening 11a and the bottom 11b, and is arranged closer to the compartment opening 11a.

[0029] The drone 100 of the present application sets the battery compartment 11 on the fuselage 10 to be open with the compartment opening 11a facing upward, so that the battery device 40 can be directly installed in the battery compartment 11 or removed from the battery compartment 11 without first removing the cover plate on the battery compartment 11, which effectively improves the efficiency of disassembling and installing the battery device 40. After the battery device 40 is installed in the battery compartment 11, part of the structure of the battery device 40 can cover the compartment opening 11a of the battery compartment 11 to prevent external liquids, dust and other debris from entering the battery compartment 11, ensuring the cleanliness of the battery compartment 11; in addition, the battery interface 12 is set in the battery compartment 11 near the compartment opening 11a, which can effectively reduce the probability of water entering the battery compartment 11 and pouring into the battery interface 12, causing the battery device 40 to fail to power supply, thereby ensuring the normal flight of the drone 100.

[0030] In some embodiments, see Figure 2 and Figure 4The battery compartment 11 includes a first bottom wall 111, a second bottom wall 112 and a side wall 113. The side wall 113 is connected to the first bottom wall 111 and the second bottom wall 112 respectively, and together they enclose the battery compartment 11, wherein the first bottom wall 111 constitutes the bottom 11b of the battery compartment 11. The battery compartment 11 is open, and the opening 11a of the battery compartment 11 is located at the top 41 of the fuselage 10. The bottom 11b and the opening 11a of the battery compartment 11 are arranged opposite to each other. The first bottom wall 111 and the second bottom wall 112 are arranged roughly in parallel. Along the direction perpendicular to the first bottom wall 111, the second bottom wall 112 is located between the bottom 11b and the opening 11a of the battery compartment 11. The battery interface 12 is arranged at the second bottom wall 112. The battery interface 12 is connected to the electrical components inside the fuselage 10. The battery interface 12 is configured to be connected to the battery device 40 in the battery compartment 11, thereby providing power to the electrical components inside the fuselage 10. Figure 4 As shown, along the direction perpendicular to the first bottom wall 111, the distance L1 between the first bottom wall 111 and the hatch 11a is greater than the distance L2 between the second bottom wall 112 and the hatch 11a, that is, the second bottom wall 112 is closer to the hatch 11a of the battery compartment 11 than the first bottom wall 111. Such a structure can prevent the accumulated water from easily entering the battery interface 12 when some water enters the battery compartment 11, since the battery interface 12 is far away from the bottom 11b of the battery compartment 11, causing the power supply of the battery device 40 to fail.

[0031] In some embodiments, see Figure 2 and Figure 5 The drone 100 further includes a water retaining wall 114, which is disposed on the second bottom wall 112 and surrounds the battery interface 12. The water retaining wall 114 extends in a direction perpendicular to the second bottom wall 112 and toward the hatch 11a. The water retaining wall 114 is used to prevent accumulated water from entering the interior of the fuselage 10 from the battery interface 12, thereby ensuring the safety of the electrical components inside the fuselage 10.

[0032] In some embodiments, see Figure 5 The drone 100 further includes an annular protrusion 115, which is disposed on the second bottom wall 112 and is located at the periphery of the water retaining wall 114. The annular protrusion 115 and the water retaining wall 114 are spaced apart to form an annular groove 1151. When the battery device 40 is installed in the battery compartment 11, the annular protrusion 115 abuts against a part of the battery device 40, and the annular groove 1151 is used to accommodate a part of the structure of the battery device 40, so that a first waterproof structure formed by the annular protrusion 115 and a second waterproof structure formed by the water retaining wall 114 are formed between the battery device 40 and the battery interface 12, and the first waterproof structure and the second waterproof structure further improve the sealing between the battery device 40 and the battery interface 12.

[0033] It is understood that, in some embodiments, the annular protrusion 115 may be a hard structure, and the hard annular protrusion 115 is abutted and connected with a soft structure on the battery device 40, such as a sealing ring, to form a sealing effect. In other embodiments, the annular protrusion 115 may be a soft structure, and the soft annular protrusion 115, such as a rubber sealing ring, is abutted and connected with a hard structure on the battery device 40, such as a battery housing, to form a sealing effect.

[0034] In some embodiments, see Figure 6 The bottom 11b of the battery compartment 11 is provided with a drainage channel 116, and the drainage channel 116 connects the bottom 43 of the battery compartment 11 with the outside. The drainage channel 116 is used to drain the accumulated water in the battery compartment 11 out of the battery compartment 11, so as to reduce the risk of the accumulated water soaking the battery device 40 and affecting the safety and performance of the battery device 40. It can be understood that the number of the drainage channels 116 can be one, two or more.

[0035] In some embodiments, see Figure 6 The drainage channel 116 has an inner drainage port 1161 and an outer drainage port 1162. The inner drainage port connects the battery compartment 11 and the drainage channel 116, and the outer drainage port 1162 connects the drainage channel 116 and the outside. The size of the outer drainage port 1162 is smaller than that of the inner drainage port 1161. During the flight of the drone 100, the air flows through the outer surface of the drone 100, and the flow rate at the smaller outer drainage port 1162 is large, so that the pressure outside the outer drainage port 1162 is greater than the pressure inside the outer drainage port 1162, thereby sucking the accumulated water out of the drainage channel 116. By setting the structure that the size of the outer drainage port 1162 is smaller than that of the inner drainage port 1161, the drainage capacity and drainage speed of the drainage channel 116 can be enhanced, and the time that the accumulated water stays in the battery compartment 11 is reduced, thereby reducing the time that the accumulated water soaks the battery device 40.

[0036] In some embodiments, see Figure 7 The battery device 40 has a top 41 and a bottom 43 opposite to each other, and a side 42 connecting the top 41 and the bottom 43. When the battery device 40 is installed in the battery compartment 11, the bottom 43 of the battery device 40 is close to the compartment bottom 11b of the battery compartment 11, and the top 41 of the battery device 40 covers the compartment opening 11a of the battery compartment 11 and is connected to the battery interface 12.

[0037] For some examples, see Figure 7The side 42 of the battery device 40 is provided with a convex rib 421, and the convex rib 421 is used to space the side 42 of the battery device 40 from the side wall 113 of the battery compartment 11. Such a structure can, on the one hand, speed up the air flow speed around the battery device 40 to facilitate heat dissipation, and on the other hand, it can allow the accumulated water that penetrates from the compartment opening 11a of the battery compartment 11 to flow smoothly to the bottom 43 of the battery compartment 11 and be discharged to the outside through the drainage channel 116.

[0038] The bottom 43 of the battery device 40 is provided with a third bottom wall 431, and the inner drain port 1161 of the battery compartment 11 is spaced apart from the third bottom wall 431, so that the accumulated water in the battery compartment 11 can enter the drainage channel 116 from the gap between the third bottom wall 431 and the inner drain port 1161 and be discharged to the outside.

[0039] As an example, a concave drainage channel 116 is provided on the first bottom wall 111 of the battery compartment 11, and the concave drainage channel 116 is spaced apart from the third bottom wall 431 of the battery device 40, so as to facilitate the flow of accumulated water. Figure 7 A foot pad 44 is provided on the third bottom wall 431 of the battery device 40, and the foot pad 44 is used to prop up the battery device 40 relative to the first bottom wall 111 of the battery compartment 11, so that the third bottom wall 431 and the inner drain port 1161 are spaced apart to facilitate the flow of accumulated water.

[0040] In some embodiments, see Figure 4 and Figure 7 A locking portion 1131 is provided on the side wall 113 of the battery compartment 11, and a locking structure 45 is provided on the side portion 42 of the battery device 40. The locking structure 45 is configured to be connected to the locking portion 1131 to lock the battery device 40 in the battery compartment 11 to prevent the battery device 40 from shaking relative to the battery compartment 11, or to prevent the battery device 40 from falling off from the battery compartment 11 when the drone 100 is rolling.

[0041] As an example, the locking portion 1131 is a locking hole, the locking structure 45 is a retractable locking column, and the battery device 40 is also provided with a handle 46 that is reciprocatingly rotated along the direction F, and the handle 46 is connected to the locking column to control the telescopic movement of the locking column relative to the side portion 42. Specifically, when the battery device 40 is placed in the battery compartment 11, the handle 46 is rotated to a flattened state, at which time the locking column extends out of the side portion 42 and is inserted into the locking hole, so that the battery device 40 is locked in the battery compartment 11; when the battery device 40 needs to be disassembled, the handle 46 is rotated to a lifted state, at which time the locking column withdraws from the locking hole and retracts into the side portion 42, so that the battery device 40 is unlocked from the battery compartment 11, and the battery device 40 can be separated from the battery compartment 11.

[0042] In some embodiments, see Figure 1 The power device 30 includes a power assembly 31 and a propeller 32. The power assembly 31 is disposed on the fuselage 10. The propeller 32 is connected to the power assembly 31 and is located above the fuselage 10. The power assembly 31 is electrically connected to the battery device 40 and drives the propeller 32 to rotate to generate lift. Figure 3 As shown, when observing the structure of the drone 100 from the top 41 of the drone 100, at least a part of the battery compartment 11 on the fuselage 10 is located within the projection range of the rotation area of ​​the propeller 32. Since the battery compartment 11 is open, a part of the battery device 40 is directly exposed to the outside. Through the above structure, on the one hand, the airflow during the rotation of the propeller 32 can be fully utilized to dissipate heat and cool the battery device 40 in the battery compartment 11, thereby preventing the battery device 40 from overheating and reducing its working performance; on the other hand, the distance for the battery device 40 to supply power to the power assembly 31 can be reduced, thereby shortening the length of the power supply wire and reducing the overall weight of the drone 100.

[0043] In some embodiments, see Figure 8 The fuselage 10 further includes a connection frame 13 and a skin 14. The connection frame 13 is arranged between the battery compartment 11 and the skin 14. The skin 14 constitutes a partial outer wall surface of the fuselage 10. The connection frame 13 is respectively connected to the first bottom wall 111, the side wall 113 and the skin 14 of the battery compartment 11. By arranging the connection frame 13 between the battery compartment 11 and the skin 14, the structural strength between the battery compartment 11 and the skin 14 can be effectively enhanced, thereby ensuring the overall structural strength of the drone 100.

[0044] The present application provides a drone 100, including a fuselage 10, wings 20, a power device 30 and a battery device 40. The wings 20 and the power device 30 are both arranged on the fuselage 10, and the wings 20 and the power device 30 provide lift for the fuselage 10. The fuselage 10 is provided with a battery compartment 11 and a battery interface 12, and the battery compartment 11 includes a relatively arranged compartment opening 11a and a compartment bottom 11b, wherein the compartment opening 11a is upwardly connected to the outside. The battery interface 12 is located at the upper part of the battery compartment 11. That is, along the direction of the compartment opening 11a of the battery compartment 11 toward the compartment opening 11a, the battery interface 12 is between the compartment opening 11a and the compartment bottom 11b, and is arranged closer to the compartment opening 11a. In the present application, by setting the battery compartment 11 to an open and upward structure, the battery can be directly installed in the battery compartment 11 or removed from the battery compartment 11 without first removing the cover plate of the battery compartment 11 for sealing, thereby improving the operation efficiency.

[0045] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application.
