[0003] In this regard, in the prior art, a frame structure is used to place the battery for the drone therein, and the frame structure is attached to the leg assembly of the drone. However, the frame often has a fixed size and cannot flexibly solve the problem that the drone needs to replace battery compartments of different sizes to accommodate batteries of different sizes or quantities in different flight scenarios.

Detailed implementation manners

[0038] The following will be combined with the attached Figure 1 To the attached Figure 7The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] It should be noted that if there are directions involved in the embodiments of the present utility model, they shall be subject to those shown in the drawings. When a specific posture changes, the directional indication shall also change accordingly.

[0040] Currently, the battery is an important power source in drones. For some short-distance flights or small drones, small-sized batteries are required, while for some large and long-distance flight drones, large-sized batteries are needed. However, the area for assembling the battery compartment in existing drones is fixed, so that the size of the battery assembled in the battery compartment is fixed, and thus it is impossible to flexibly replace the battery compartments of different sizes to accommodate different sizes or quantities of batteries. The existing battery compartments have the problem of being unable to adapt to different flight scenarios of drones.

[0041] In view of this, the inventor of the present application provides a drone, aiming to be able to replace battery compartments of different sizes to accommodate different sizes or quantities of batteries according to different flight scenarios of the drone, so that the battery compartments can adapt to different flight scenarios of the drone.

[0042] As Figure 1 shown, a drone of the present technical solution includes a fuselage 10. An arm assembly 11 is circumferentially arranged on the fuselage 10. The arm assembly 11 is arranged along the circumference of the fuselage 10 in an array. A functional assembly 12 is arranged at the outer end of the arm assembly 11. The functional assembly 12 is used to support the flight of the drone. A battery compartment 13 is connected to the fuselage 10. In this embodiment, the battery compartment 13 is located below the fuselage 10. A leg assembly 14 is arranged below the fuselage 10. The leg assembly 14 is longitudinally arranged around the battery compartment 13 in an array, and a part of the leg assembly 14 is assembled and connected to the battery compartment 13, so that the battery compartment 13 is attached to the leg assembly 14.

[0043] As Figure 2 shown, the leg assembly 14 encloses an assembly area 141 capable of assembling the battery compartment 13; An adjustment and locking structure 15 is assembled on the leg assembly 14; The adjustment and locking structure 15 is assembled and connected to the battery compartment 13; The adjustment and locking structure 15 slides from a first position A to a second position B along the length direction of the leg assembly 14 and is locked at the second position B.

[0044] It should be understood that when the adjustment locking structure 15 slides along the tripod assembly 14 towards the fuselage 10, the assembly area 141 becomes smaller, so that a battery compartment 13 of a small size can be assembled; when the adjustment locking structure 15 slides along the tripod assembly 14 away from the fuselage 10, the assembly area 141 becomes larger, so that a battery compartment 13 of a large size can be assembled. And when the adjustment locking structure 15 is adjusted to a proper position, for example, sliding from the first position A to the second position B, it can also be locked at the second position B, so that after the battery compartment 13 is assembled in the assembly area 141, the situation that the battery compartment 13 falls downward under the action of gravity can be avoided.

[0045] Specifically, as Figure 3 shown, the adjustment locking structure 15 includes a clamping body 151, the clamping body 151 has two opposite clamping arms 1511, the two opposite clamping arms 1511 enclose a semi-closed cylindrical structure, the tripod assembly 14 is assembled in the cylindrical structure, and the diameter of the cylindrical structure enclosed by the two opposite clamping arms 1511 is greater than or equal to the diameter of the tripod assembly 14, so as to realize that the cylindrical structure can slide up and down on the outer surface of the tripod assembly 14.

[0046] Furthermore, a connecting mechanism 152 is arranged at the end of each clamping arm 1511 to allow the clamping arm 1511 to tightly wrap around the tripod assembly 14 and be fixed through the connecting mechanism 152.

[0047] During assembly, after the adjustment locking structure 15 slides to a proper position, by pulling closer the connecting mechanisms 152 located on each clamping arm 1511, the pressure of the two opposite clamping arms 1511 on the tripod assembly 14 is increased respectively, so as to lock the adjustment locking structure 15 at this position.

[0048] Specifically, the connecting mechanism 152 includes at least one bolt hole 1521; the bolt hole 1521 is located at the end of each clamping arm 1511; it also includes one or more bolts 1522 and nuts 1523, the bolts 1522 are used to pass through the two opposite bolt holes 1521, and the clamping body 151 is locked or unlocked on the tripod assembly 14 by loosening or tightening the bolts 1522.

[0049] It should be understood that after the adjustment and locking structure 15 slides to a proper position, the bolt 1522 is passed through two opposite bolt holes 1521 until the bolt 1522 is stopped on the upper surface of the bolt hole 1521 and cannot be screwed in further, and the other end of the bolt 1522 is exposed on the other side of the bolt hole 1521. Then, the nut 1523 is sleeved on the exposed bolt hole 1521, and the nut 1523 is rotated to make it approach and rotate relative to the bolt hole 1521, so as to reduce the distance between two opposite clamping arms 1511, and thus achieve the purpose of fixing the adjustment and locking structure 15 at a proper position. On the contrary, when it is necessary to adjust the position of the adjustment and locking structure 15, only the nut 1523 needs to be loosened to make the two opposite clamping arms 1511 relax the clamping force on the tripod assembly 14, so that the adjustment and locking structure 15 can slide up and down on the tripod assembly 14.

[0050] However, since the battery compartment 13 is equipped with a battery inside, its weight is relatively heavy. During the use of the drone, the connection between the battery compartment 13 and the tripod assembly 14 is prone to looseness, resulting in the battery compartment 13 not being firmly attached to the tripod assembly 14.

[0051] In this regard, as Figure 4 and Figure 5 shown, the adjustment and locking structure 15 of the present technical solution further includes a loosening prevention mechanism 153; the loosening prevention mechanism 153 includes through holes 1531 provided on each clamping arm 1511, and a positioning pin 1532; the positioning pin 1532 is inserted into the through hole 1532 until it contacts the tripod assembly 14 provided in the clamping arm 1511.

[0052] In this embodiment, during assembly, after the positioning pin 1532 is inserted, it abuts against the tripod assembly 14, so that the adjustment and locking structure 15 cannot move in position on the tripod assembly 14.

[0053] In some other embodiments, through holes 143 are provided on the tripod assembly 14. The aperture of the through hole 143 is adapted to the aperture of the through hole 1531 and penetrates the left and right tube walls of the tripod assembly 14. When the positioning pin 1532 passes through the through holes 143 and 1531 in sequence, the adjustment and locking structure 15 is locked in this position, thereby preventing the battery compartment 13 from being loosely attached to the tripod assembly 14.

[0054] To make the assembly of the battery compartment 13 and the adjustment and locking structure 15 more fitting, as Figure 5As shown, further, the adjustment and locking structure 15 further includes an assembly mechanism 154; the assembly mechanism 154 includes a flange 1541 and a limiting member 1543; the flange 1541 has a through hole 1542; the assembly mechanism 154 further includes an assembly hole 161 on the base 16 of the battery compartment 13, and the assembly hole 161 is correspondingly assembled with the through hole 1542; the limiting member 1543 sequentially passes through the assembly hole 161 and the through hole 1542 to realize the assembly connection between the battery compartment 13 and the adjustment and locking structure 15.

[0055] It should be noted that, in this embodiment, one end of the flange 1541 is inclined with respect to the clamping arm 1511, so that after the adjustment and locking structure 15 is assembled on the tripod assembly 14, the lower surface of the adjustment and locking structure 15 is in close contact with the assembly surface of the battery compartment 13, that is, the bottom surface of the flange 1541 is in close contact with the upper surface near the hole of the assembly hole 161. This makes the entire battery compartment 13 and the adjustment and locking structure 15 more stably installed, preventing the battery compartment 13 from being prone to jolting due to gravity during the flight or landing of the drone. It should be noted that, in this embodiment, the assembly method between the battery compartment 13 and the adjustment and locking structure 15 is a detachable assembly connection, such as a screw assembly connection or the like.

[0056] In some other scenarios, the assembly connection between the adjustment and locking structure 15 and the battery compartment 13 further includes a fixed connection, such as welding, etc. It should also be noted that multiple adjustment and locking structures 15 can be provided according to actual needs.

[0057] Further, as also Figure 5 shown, the battery compartment 13 has a base 16; the base 16 is assembled and connected with the adjustment and locking structure 15.

[0058] In some application scenarios, especially for the convenience of transporting the drone, since the battery compartment 13 is usually a large-sized frame structure, in this embodiment, the battery compartment 13 is a three-dimensional structure formed by enclosing four transverse panels 132 and two longitudinal panels 133 to form a hollow inner cavity 136 for assembling the battery. Two of the transverse panels 132 and two of the longitudinal panels 133 are assembled and connected with the base 16, and this assembly connection can be, for example, a screw and nut connection or a slot and block connection. When transportation is required, the battery compartment 13 can be disassembled into several small pieces for convenient transportation.

[0059] It should be noted that in this embodiment, the battery compartment 13 is assembled and connected to the adjustment and locking structure 15 through the base 16. Specifically, at the position on the base 16 adapted to the adjustment and locking structure 15, there is also a locking assembly hole 161 correspondingly. The assembly hole 161 and the through hole 1542 are assembled and connected through the limiting member 1543.

[0060] For the convenience of battery replacement, the battery compartment 13 further has a covering portion 131 and a compartment opening 134. The covering portion 131 is used to cover the compartment opening 134 of the battery compartment 13. The covering portion 131 is provided on one side of the battery compartment 13 and is rotatably connected to the battery compartment 13.

[0061] The covering portion 131 has a bolt 135. One end of the bolt 135 is connected to the covering portion 131, and the other end is connected to the adjacent transverse panel 132 or longitudinal panel 133 of the covering portion 131. The bolt enables the covering portion 131 to close the compartment opening 134. When the battery needs to be replaced, only the bolt 135 needs to be opened, and the covering portion 131 is pushed to expose the compartment opening 134, so that the battery can be replaced.

[0062] As Figure 7 shown, an anti-slip sleeve 142 is sleeved on the bottom of the tripod assembly 14. In this embodiment, the cross-section of the anti-slip sleeve 142 presents an annular structure. In some other embodiments, the cross-section of the anti-slip sleeve 142 presents shapes such as triangular, U-shaped, etc. Preferably, an anti-slip sleeve 142 is sleeved on the bottom of each tripod assembly 14 respectively.

[0063] In this embodiment, the anti-slip sleeve 142 is sleeved on the bottom of the tripod assembly 14. The bottom is the part of the tripod assembly 14 that contacts the landing surface. When the drone lands, due to the inertial effect, it is not easy for the drone to land stably on the landing surface. However, the anti-slip sleeve 142 in this embodiment can increase the friction with the landing surface, so that when the drone lands, it is not easy to slip and stand unsteadily.

[0064] In addition, the tripod assembly 14 also has a socket connector 144. The socket connector 144 is used to mount an external power socket, and the external power socket is electrically connected to the battery disposed inside the battery compartment 13. The socket connector 144 can be provided with multiple ones according to actual needs.

[0065] In summary, for a drone of the present technical solution, the adjustment and locking structure 15 is provided on the tripod assembly 14. The adjustment and locking structure 15 can slide up and down on the outer peripheral surface of the tripod assembly, so that the assembly area 141 for assembling the battery compartment 13 changes according to the adjustment to adapt to battery compartments 13 of different sizes, so as to adapt to more flight scenarios of the drone.
