[0002] A drone is an aircraft that can be remotely or autonomously controlled without humans on board. In recent years, it has made significant progress in technological innovation and expansion of application scenarios, becoming an important force driving change in multiple industries.

[0003] Existing drone structures, such as frames and other parts, are generally made by injection molding, which requires mold opening and is costly.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See Figures 1-8 , the present invention provides the following three technical solutions:

[0035] The first embodiment: a waterproof quadrotor multi-axis drone, comprising:

[0036] The drone frame is assembled by modularizing stamped sheet metal parts, and the control module 1 and power supply 2 are installed on the drone frame;

[0037] The flight unit is installed at the four corners of the drone frame and is used for drone flight;

[0039] The sealing shell 4 is installed on the UAV frame, and a sealing structure is provided between the contact surface of the sealing shell 4 and the UAV frame.

[0040] The center of the drone frame includes, from top to bottom, a battery substrate 5, a fixing ring plate 6, a chip substrate 7, and a gripper mounting plate 8. The power supply 2 is bound to the bottom of the battery substrate 5 by a strap, which can be a cable tie. The control module 1 is a chip and is mounted on the top of the chip substrate 7 by screws. The battery substrate 5, chip substrate 7, and gripper mounting plate 8 are all fixed in series by long screws, and the outer sleeve of the long screw is provided with a sleeve column 19 for supporting and separating the battery substrate 5, chip substrate 7, and gripper mounting plate 8.

[0041] The drone frame also includes arms 9 at the four corners. The arms 9 are sandwiched between the fixed ring plate 6 and the chip substrate 7 and fixed together with screws. A section of the arms 9 away from the fixed ring plate 6 is fixed to the flight unit. The control module 1 is connected to the power supply 2 and the flight unit through wires. A wire housing 10 is also installed on the arms 9 to cover the wires of the flight unit.

[0042] The battery substrate 5, the fixed ring plate 6, the chip substrate 7, the grabber mounting plate 8 and the machine arm 9 are all stamped plate parts, and through holes for mounting bolts are punched on the battery substrate 5, the fixed ring plate 6, the chip substrate 7, the grabber mounting plate 8 and the machine arm 9;

[0043] The flight unit includes a wing protection frame 11 installed on the top of one end of the arm 9, a motor 12 is installed on the wing protection frame 11, and the output end of the motor 12 is fixedly connected to the wing 13, a support foot 14 is installed at the bottom of one end of the arm 9, and the support foot 14, the arm 9, the wing protection frame 11 and the motor 12 are fixed as a whole by bolts, and a foot pad 15 is also installed at the bottom of the support foot 14.

[0044] The main frame of the drone is made of stamped plates, which are easy to process and assemble and have low cost. The electronic components are installed in layers, with a reasonable layout and easy installation. In addition, a sealing structure is provided in the gap of the sealed shell 4 to ensure the waterproof performance of the drone, thereby improving the adaptability of the equipment to the environment. At the same time, a grabber 3 can be installed at the bottom of the drone to realize the automatic grabbing function.

[0045] The second embodiment is mainly different from the first embodiment in that: the sealed shell 4 includes an upper shell 41 and a lower shell 42, the upper shell 41 and the lower shell 42 enclose the battery substrate 5, the fixing ring plate 6, the chip substrate 7 and the grabber mounting plate 8, and the four corners of the upper shell 41 and the lower shell 42 are provided with a notch for passing the machine arm 9, the contact surfaces of the upper shell 41 and the lower shell 42 are provided with an inwardly extending groove, and a sealing rubber ring 43 is provided in the groove. The sealing rubber ring 43 is a rubber strip bonded in electronic products such as mobile phones. The sealing rubber ring 43 is used to seal and bond the contact surface of the upper shell and the lower shell. When the upper shell 41 and the lower shell 42 need to be disassembled, the joint is heated to cause the sealing rubber ring 43 to melt. A rubber sleeve 44 covering the machine arm 9 is clamped in the notch of the upper shell 41 and the lower shell 42;

[0046] The side of the rubber sleeve 44 is provided with an annular groove 441 adapted to the upper shell 41 and the lower shell 42. The inside of the rubber sleeve 44 is provided with a slot 442 adapted to the flight unit wire and a through hole 443 adapted to the machine arm 9.

[0047] The flight unit wires are divided into two sections, connected by a male connector 16 and a female connector 17. Slots 442 fit over these connectors, each with a raised ring 18 on its exterior. During installation, the rubber sleeve 44 is first placed over the arm 9, and then the male and female connectors 16, 17 are inserted through the sleeve 44, keeping them inside. The raised ring 18 presses against the inner wall of the sleeve 44 to improve sealing.

[0048] By setting different sealing structures at various possible leakage positions of the sealed shell 4, especially setting rubber sleeves 44 at the positions of the arms 9 and wires where there are more irregular gaps, the irregular cross-section is converted into a regular cross-section, which is convenient for sealing, effectively ensuring the sealing isolation effect between the inside and the outside, and ensuring the waterproof performance of the drone.

[0049] The third embodiment is mainly different from the first embodiment in that the grabber 3 includes a motor 31 and a mounting plate 32 fixedly connected to the upper and lower surfaces of the grabber mounting plate 8 by bolts, the bottom of the mounting plate 32 is rotatably connected to a rotating drum 33, and the top of the rotating drum 33 is fixedly connected to a prismatic shaft 34 that passes through the top of the mounting plate 32, the output end of the motor 31 is installed with a prismatic sleeve 35 that is sleeved with the prismatic shaft 34, the four corners of the bottom of the mounting plate 32 are rotatably connected to the clamping jaws 36, the clamping jaws 36 are connected to the rotating drum 33 by a pull rod 37, and the two ends of the pull rod 37 are connected in a ball head manner, the bottom of the grabber mounting plate 8 is provided with an extension sleeve that is adapted to the bolts and the prismatic sleeve 35, the bottom end of the extension sleeve passes through the bottom of the lower shell 42, and a sealing ring is provided in the gap between the extension sleeve and the lower shell 42, and the extension sleeve is plugged with a sealing rubber plug for sealing when the grabber 3 is not installed. By controlling the motor 31, the drum 33 can be driven to rotate, and then the clamping claws 36 on the four sides can be pulled through the pull rod 37. The connection method of the ball heads at both ends of the pull rod 37 ensures that the horizontal angle of the pull rod 37 does not affect the vertical rotation of the clamping claws 36.

[0050] The grabbing arm 3 is driven by a motor 31, which can simultaneously realize the synchronous deflection of the four clamping jaws 36 toward the middle, thereby achieving the effect of automatic grabbing, and the grabbing arm 3 can be disassembled or installed as needed, and the sealing can be always maintained by setting a corresponding sealing structure.
