[0035] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0036] Ginseng Figures 1 to 9 A specific embodiment of a drone fuselage disclosed in the utility model, the fuselage 1 is composed of a frame 11 and a landing gear 12, the frame 11 forms a receiving opening 13 for placing a drone box 5, the box 5 is placed in the receiving opening 13 and is located in a receiving space 14 formed by the receiving opening 13 and the landing gear 12 in the height direction, and the frame 11 is located at a position away from the receiving opening 13 to install a battery installation assembly 2 for connecting a battery 3. Compared with the prior art in which the battery is installed inside the drone fuselage, thereby occupying the storage space of the box, the utility model avoids occupying the internal space of the fuselage 1 by installing the battery installation assembly 2 at a position of the frame 11 away from the receiving space 14, thereby achieving the completion of the sowing task without increasing the size of the fuselage 1 and changing the shape of the box 5, thereby avoiding the problem of increasing the load of the drone and the problem of the special-shaped box affecting the installation and heat dissipation of the battery.

[0037] Ginseng Figures 1 to 9 As shown, in this embodiment, the battery mounting assembly 2 and the control assembly mounting assembly 6 are respectively installed on both sides of the frame 11 away from the receiving opening 13, and the frame 11 is equipped with several Figure 1 and Fig. 9 The support arm 15 shown in the figure has a fuselage 1 with an air avoidance area 16 for the support arm 15 to be folded toward the side of the frame 11. The battery mounting assembly 2 and the control assembly mounting assembly 6 are both located outside the air avoidance area 16 of the support arm 15. The fuselage 1 is detachably connected to the battery 3 via the battery mounting assembly 2.

[0038] The longitudinal space formed by the receiving opening 13 of the frame 11 and the height direction of the landing gear 12 constitutes a receiving space 14, and the box 5 of the drone is placed in the receiving space 14 through the receiving opening 13. The battery mounting assembly 2 is arranged on the side of the frame 11 away from the receiving opening 13 and connected to the frame 11. When the box 5 for storing liquid medicine or seeds to be sown is placed in the receiving space 14 through the receiving opening 13, since the battery mounting assembly 2 is arranged at a position of the fuselage 1 away from the receiving space 14, the battery 3 is not installed between the battery mounting assembly 2. It will occupy the space in the receiving opening 13 and the receiving space 14, that is, it will not occupy the space inside the fuselage 1 for receiving the box 5, so that the box 5 with a conventional volume and a conventional shape can be installed in the fuselage 1 of conventional size and weight without the interference of the battery 3, and the volume of the box 5 that can be installed in the fuselage 1 can be increased to a certain extent to avoid the problem of increasing the invalid load of the fuselage 1, and the battery 3 is installed at a position away from the frame 11 and away from the receiving opening 13, and the box 5 and the battery 3 do not interfere with each other, which is convenient for plugging and unplugging and heat dissipation of the battery 3. When the battery 3 is installed in the battery installation assembly 2, it forms an angle less than or equal to 90° with the length direction of the fuselage 1. Specifically, in this embodiment, when the battery 3 is installed in the battery installation assembly 2, the angle formed with the length direction of the fuselage 1 is 90°.

[0039] Ginseng Figure 1 as well as Figures 3 to 9 As shown, it should be noted that the frame 11 is formed in an integral manner, the receiving opening 13 is formed in the center of the integrally formed frame 11, and, or the frame 11 is composed of a plurality of connecting rods, the receiving opening 13 is formed by enclosing a plurality of connecting rods, and the battery mounting assembly 2 is arranged on the side of the frame 11 away from the receiving opening 13. Specifically, in this embodiment, the frame 11 has two first connecting rods 111 arranged along the length direction of the fuselage 1 and two second connecting rods 112 arranged along the width direction of the fuselage 2, and the two first connecting rods 111 and the two second connecting rods 112 are connected end to end to form the receiving opening 13; and, the frame 11 is connected to four support arms 15, and the four support arms 15 are respectively installed at four connection points formed by the two first rod bodies 111 and the two second connecting rods 112 enclosing the receiving opening 13, and the four support arms 16 are in a folded state as shown Fig. 9 As shown, two first connecting rods 111 (the first connecting rods 111 are marked as Figure 2 and Figure 3As shown), therefore, the air avoidance area 16 is formed on the side where the two first connecting rods 111 are away from each other; the two second connecting rods 112 are respectively the first rod body 1121 and the second rod body 1122, the second rod body 1122 is arranged behind the first rod body 1121 along the flight direction of the fuselage 1, the battery mounting assembly 2 is connected to the side of the second rod body 1122 away from the first rod body 1121, and the upper surface of the first rod body 1121 is connected to the control assembly mounting assembly 6 of the drone. The landing gear 12 includes a first landing rod 121 and a second landing rod 122, and the first landing rod 121 and the second landing rod 122 respectively have two top connecting ends connected to the two ends of the length direction of the bottom surface of the two first rod bodies 11, and the first landing rod 121 and the second landing rod 122 are connected between the reinforcement rod 123.

[0040] The fuselage 1 surrounded by the landing gear 12 and the frame 11 forms a shape that is approximately a prism with a small top and a large bottom, so that the fuselage 1 has better stability when placed on the take-off plane. Therefore, the accommodating space 14 formed between the landing gear 12 and the frame 11 is larger than the volume of the box 5 that can be stably placed in the accommodating opening 13. Therefore, no matter whether the battery mounting assembly 2 is installed on the frame 11 or the landing gear 12 is installed on the side away from the accommodating space 14, the purpose of non-interference between the battery 3 and the box 5 can be achieved, thereby ensuring that the box 5 has sufficient volume.

[0041] According to the above description, when the fuselage 1 is in flight, based on the flight direction of the fuselage 1, the first rod 1121 is located in front of the second rod 1122, that is, the first rod 1121 is the head of the drone, which is used to install drone functional modules such as the camera module (not shown), the lighting module (not marked), and the control assembly installation component 6. Furthermore, the frame 11 as a whole also needs to be connected to the support arm 15 to install the power structure mainly composed of the motor and the propeller ( Figure 1 The dotted line in FIG. 1 is a circle formed by taking the end point of the support arm 15 as the center. The support arm 15 is Fig. 9 In the clearing area 16 shown, turn to close Figure 3 and Figure 4The positions of the two first connecting rods 111 are shown so as to be folded and stored. Taking the aforementioned first rod body 1121 as the head of the drone as an example, the two first connecting rods 111 are the left and right sides of the fuselage 1. In this embodiment, the two first connecting rods 111 are also respectively provided with clamping seats 1111 for clamping the support arm 15 in the storage state. When the support arm 15 is rotated and folded in the air avoidance area 16 to a state close to being in contact with the first connecting rod 111, it is clamped and fixed by the clamping seat 1111. Therefore, by connecting the battery mounting assembly 2 to the side of the second rod body 1122 away from the first rod body 1121, while avoiding occupying the accommodating space 14 to ensure that the box body 5 has sufficient storage space, the support arm 15 can be smoothly folded in the air avoidance area 16 without interference, which is further beneficial to the movement and storage of the entire drone. Furthermore, by installing the battery mounting assembly 2 on the second rod body 1122, when the battery 3 is installed on the battery mounting assembly 2, the weight of the drone modules such as the control assembly mounting assembly 6 installed on the first rod body 1121 can be balanced, thereby ensuring a stable flight posture of the drone.

[0042] Specific reference Figures 4 to 8 As shown, the battery installation assembly 2 includes a first connecting portion 21 and a second connecting portion 22, and the first connecting portion 21 and the second connecting portion 22 are connected to the side of the second rod body 1122 away from the accommodating port 13. The first connecting portion 21 and the second connecting portion 22 are symmetrically distributed along the symmetry axis of the second rod body 1122 perpendicular to the length direction, and the first connecting portion 21 and the second connecting portion 22 are relatively close to one side to form an accommodating groove 23 for the battery 3 to be placed therein; the first connecting portion 21 has a first power interface 2121, and the second connecting portion has a second power interface 2221, and the first power interface 2121 and the second power interface 2221 are used to electrically connect the battery 3. The first connection part 21 includes a first end plate 212 and a first boss 211, the first end plate 212 is fixedly connected to the top of the first boss 211, and the first power interface 2121 is arranged on the upper surface of the first end plate 212. The second connection part 22 includes a second end plate 222 and a second boss 221, the second end plate 222 is fixedly connected to the top of the second boss 221, and the second power interface 2221 is arranged on the top surface of the second end plate 222. When the battery 3 is placed in the receiving groove 23, it is connected and electrically connected to the first power interface 2121 and the second power interface 2221. It should be noted that two mounting crossbeams 1123 are vertically fixed to the side of the second rod body 1122 away from the first rod body 1121, and the first connection part 21 and the second connection part 22 are connected to the first rod body 1121. Figure 2 and Figure 5 The state shown is assembled at the mounting beam 1123.

[0043] The utility model also discloses a drone, including the drone fuselage described in the above-mentioned embodiment, still combined with Figures 1 to 9It is described that the battery mounting assembly 2 is equipped with a battery 3, and the battery 3 includes a body 33 and a top cover 31 located on the top of the body 33. The two ends of the top cover 31 in the length direction are set as two lugs 311, and the two lugs 311 each include a connecting surface 312, and the two connecting surfaces 312 are respectively provided with a first polarity connector (not shown) and a second polarity connector (not shown); the battery mounting assembly 2 supports the two lugs 311, and the battery mounting assembly 2 has an interface electrically connected to the first polarity connector (not shown) and the second polarity connector (not shown). Specifically, the battery mounting assembly 2 in this embodiment is consistent with the aforementioned embodiment, and is composed of a first connecting portion 21 including a first end plate 212 and a first boss 211, and a second connecting portion 22 including a second end plate 222 and a second boss 221. Therefore, the interface electrically connected to the first polarity connector (not shown) and the second polarity connector (not shown) is specifically a first power interface 2121 arranged on the top surface of the first end plate 212 and a second power interface 2221 arranged on the top surface of the second end plate 222. Specifically, the first power interface 2121 is a positive electrode interface, and the second power interface 2221 is a negative electrode interface.

[0044] After the battery 3 is inserted between the first connection portion 21 and the second connection portion 22, the connection surfaces 312 of the two lugs 311 are in contact with the top surfaces of the first end plate 212 and the second end plate 222, and the first polarity connector and the second polarity connector are electrically connected to the first power interface 2121 and the second power interface 2221. Figure 2 When placed in the accommodating opening 13 in the shown state, there is enough space above the battery mounting assembly 2 for plugging and unplugging the battery 3. Taking docking the battery 3 to the battery mounting assembly 2 as an example, align the bottom end of the battery 3 with the top opening of the accommodating groove 23 between the first connecting portion 21 and the second connecting portion 22, so that the battery 3 moves downward as a whole and slides in the accommodating groove 23 until the top cover 31 of the battery 3 is buckled on the top of the first connecting portion 21 and the second connecting portion 22. At this time, the mounting surfaces 312 of the two lugs 311 are supported by the top surfaces of the first end plate 212 and the second end plate 222, respectively, and the first polarity connector and the second polarity connector are electrically connected to the first power interface 2121 and the second power interface 2221, respectively, to supply power to various modules of the drone. When the battery 3 needs to be removed, lift the battery 3 as a whole to move the lug 311 away from the first end plate 212 and the second end plate 222, and the first polarity connector and the second polarity connector are disengaged from the first power interface 2121 and the second power interface 2221, and continue to lift the battery 3 to completely move it out of the accommodating groove 23 between the first connecting part 21 and the second connecting part 22.

[0045] Ginseng Figures 4 to 8As shown, the battery installation assembly 2 includes a guide portion that limits the vertical movement of the body 33, the body 33 is provided with a matching portion extending vertically, and the guide portion and the matching portion are matched in a concave-convex manner; the guide portion includes two protrusions 26, and the matching portion includes two grooves 32 distributed on both sides of the body 33, the grooves 32 are matched in a concave-convex manner with the protrusions 26, and the protrusions 26 are provided with a friction-reducing layer 24, and the friction-reducing layer 24 is set as a plurality of rollers 23 evenly distributed along the height direction of the protrusion 26, and the rollers 23 roll and rub against the groove wall of the groove 32. Specifically, the two protrusions 26 are respectively formed on the side relatively close to the first boss 211 and the second boss 221, and after the battery 3 is placed in the receiving groove 23, the two grooves 32 are respectively matched in a concave-convex manner with the two protrusions 26, and the battery 3 as a whole slides downward in the vertical direction under the guidance of the protrusions 26 (i.e., the battery 3 is pulled out and installed).

[0046] It should be noted that the first boss 211 and the second boss 221 in this embodiment are both selected to be materials with greater strength and certain toughness, such as carbon fiber, polyethylene and polypropylene, so as to avoid collision damage between the drone and the body 33 of the battery 3 due to vibration during flight. In the process of installing the battery 3 to the battery mounting assembly 2, the bottom ends of the grooves 32 on both sides of the battery 3 are aligned with the protrusions 26 on the first boss 211 and the second boss 221, and the grooves 32 slide downward relative to the protrusions 26 during the overall downward movement of the battery 3 until the first polarity connector and the second polarity connector of the battery 3 are docked with the first power interface 2121 and the second power interface 2221. Through the cooperation between the grooves 32 and the protrusions 26, the longitudinal movement direction of the battery 3 is limited, which plays an effective limiting and guiding role. When the groove 32 rises and falls along the protrusion 26, the friction between the groove 32 and the protrusion 26 is effectively reduced by the relative rolling friction of the roller 23 with respect to the groove wall of the groove 32, so that the insertion and removal process of the battery 3 is smoother, and the friction between the body 33 and the protrusion 26 is effectively reduced, thereby effectively extending its service life. It should be noted that the friction-reducing layer 24 can also be set as a guide rail or other components with guiding and friction-reducing functions.

[0047] Ginseng Figures 4 to 8As shown, the battery installation assembly 2 is provided with a plurality of support members 25 around the interface, that is, the top surfaces of the first end plate 212 and the second end plate 222 are provided with a plurality of support members 25 around the first power interface 2121 and the second power interface 2221, and the support members are inserted into the connection surface 312 of the lug to support the lug 311, and at the same time, the first polarity connector and the second polarity connector are electrically connected to the corresponding interface, that is, the first power interface 2121 and the second power interface 2221. It should be noted that the connection surface 312 is provided with a receiving groove (not shown) adapted to the support member 25, and when the two connection surfaces 312 are in contact with the upper surfaces of the first end plate 212 and the second end plate 222, the support member 25 is inserted into the receiving groove, and the first polarity connector and the second polarity connector are respectively connected to the first power interface 2121 and the second power interface 2221. By setting the support member 25, the support member 25 can share the weight of the battery 3, so as to avoid the weight of the battery 3 being completely borne by the first power interface 2121 and the second power interface 2221, thereby preventing the battery 3 from being damaged. In addition, by designing the support member 25 and the receiving groove provided on the connection surface 312, the battery 3 can be effectively prevented from being misplaced during installation. The battery 3 can only be connected when the support member 25 is accurately inserted into the receiving groove, further improving the accuracy of the overall structure of the battery installation assembly 2. It should be noted that Figure 5 In the shown state, the battery 3 has not yet been installed.
