[0031] Please see Figure 1 , Figure 2 and Figure 3 This application provides a detachable quadcopter 100, which includes a body 10 and a plurality of arm assemblies 20, wherein the arm assemblies 20 are detachably mounted on the periphery of the body 10; wherein the arm assemblies 20 are provided with hook-lock assemblies 30, and the arm assemblies 20 are connected to the body 10 through the hook-lock assemblies 30.
[0032] Specifically, the fuselage 10 serves as the mounting platform, the core mounting platform of the entire aircraft. It is also a key component connecting the four arms 21, allowing them to be distributed in a reasonable layout around the fuselage 10, thus forming a stable flight platform. Furthermore, the fuselage 10 serves to support and connect components, bearing the weight of the entire aircraft. Generally, the fuselage 10 uses high-strength yet lightweight materials, such as carbon fiber, to reduce weight while ensuring sufficient strength to support other components. In addition, the design of the fuselage 10 also protects internal equipment: the outer shell of the fuselage 10 provides a certain degree of protection against damage from external objects, dust, rain, and other factors during flight. Moreover, the fuselage 10 maintains the flight balance and stability of the quadcopter 100: the shape and mass distribution of the fuselage 10 are crucial to the flight balance and stability of the quadcopter 100. A well-designed fuselage 10 ensures a reasonable center of gravity distribution for the quadcopter 100, maintaining a stable attitude during flight. For example, if the shape of the fuselage 10 is symmetrical and the weight is evenly distributed, then when the four motors 22 generate power to propel the quadcopter 100 into flight, it can better resist external interference, such as wind, and keep the quadcopter 100 flying stably.
[0033] In one embodiment, the arm assembly 20 is installed around the fuselage 10, serving to transmit power and lift and adjust flight attitude. In this application, the arm assembly 20 is detachably mounted on the periphery of the fuselage 10 and can be removed from the fuselage 10. Specifically, the arm assembly 20 is provided with a hook-lock assembly 30, which connects the arm assembly 20 to the fuselage 10. The design is simple and the connection is convenient. The hook-lock assembly 30 design improves the assembly efficiency of the quadcopter 100, facilitates maintenance, and provides high flexibility.
[0034] Please see Figure 4 The hook-lock assembly 30 includes a hook body 31, a bracket 32, and a torsion spring 33. One end of the hook body 31 is provided with a locking hook 34 for hooking the machine body 10. The first end 321 of the bracket 32 has a first opening for accommodating the locking hook 34 of the hook body 31. The second end 322 of the bracket 32 includes a second opening, through which a fixed shaft 35 passes. The torsion spring 33 is coaxially arranged with the fixed shaft 35. One end of the torsion spring 33 abuts against the hook body 31, and the other end abuts against the machine arm assembly 20.
[0035] Specifically, through the design of the torsion spring 33, the locking hook 34 of the hook body 31 can move in the first opening of the bracket 32, and is used to hook the machine body 10 through the locking hook 34 during assembly, so as to connect the arm assembly 20 and the machine body 10. At the same time, a fixing shaft 35 is set in the second opening of the bracket 32 to fix the position of the torsion spring 33 and the hook body 31, which facilitates the application of the hook-lock assembly 30.
[0036] Please continue reading. Figure 4 The hook-lock assembly 30 also includes a hook sleeve 36, which is used to hold the boom assembly 20. The boom assembly 20 and the hook sleeve 36 are located on the same side of the bracket 32. Specifically, during the assembly process, the boom assembly 20 and the hook-lock assembly 30 can be assembled together first, and then the assembled structure can be installed onto the machine body 10. When assembling the boom assembly 20 and the hook-lock assembly 30, the hook sleeve 36 is used to fix the position of the boom assembly 20. Both the bracket 32 and the hook sleeve 36 abut against the boom assembly 20, which is beneficial to the stability of the overall structure and improves the installation efficiency.
[0037] Please continue reading. Figure 4 The hook body 31 also includes a mounting plate 37, which is perpendicular to the main body of the hook body 31 and has a mounting hole. The fixing shaft 35 passes through the mounting hole, allowing the hook body 31 to rotate around the fixing shaft 35. Specifically, the hook body 31 is mounted to the bracket 32 via the mounting plate 37, and the fixing shaft 35 passes through the mounting hole of the mounting plate 37, allowing the mounting plate 37 to rotate around the fixing shaft 35, thus achieving a rotatable connection between the hook body 31 and the bracket 32.
[0038] Please see Figure 5 and Figure 6 The body 10 includes a body base plate 11, a quick-release plate 12, and a body upper plate 13 arranged sequentially. The body base plate 11 has multiple through holes 111 for engaging with the hook lock assembly 30 to accommodate the locking hook 34 of the hook body 31. The quick-release plate 12 includes a recessed area 121 that matches the protrusion of the arm 21 in the arm assembly 20 for fixing the arm 21. Specifically, the quick-release plate 12 is recessed within the body base plate 11 and body upper plate 13 in the installation area, providing space for installing the arm 21. The portions of the body base plate 11 and body upper plate 13 that protrude from the quick-release plate 12 are used to clamp the arm 21, ensuring the installation effect. Simultaneously, the body base plate 11 has through holes 111 through which the locking hook 34 passes to be fixed to the body 10. Additionally, the quick-release plate 12 includes a recessed area 121 that matches the protrusion of the arm 21 for fixing the arm 21. Meanwhile, the quick-release plate 12 is provided with a through hole 122 for connecting with the bottom plate 11 and the upper plate 13 of the fuselage.
[0039] Please continue reading. Figure 5 and Figure 6The casing 10 also includes a battery mounting bracket 14 and a support column 15. The battery mounting bracket 14 is located on the upper side of the casing 10 and is used to fix the battery 181. The support column 15 connects the casing base plate 11 and the battery mounting bracket 14. Specifically, the design of the support column 15 provides a space between the battery mounting bracket 14 and the casing base plate 11. At the same time, the design of the battery mounting bracket 14 facilitates fixing the battery 181 to the upper side of the casing 10, which is beneficial to the overall compact structural design.
[0040] Please continue reading. Figure 5 The fuselage 10 also includes a flight control board 16, located between the battery mounting bracket 14 and the upper fuselage plate 13. The flight control board 16 has quick-connect plugs 161 on both sides of the quadcopter 100's forward direction for connecting to the wiring on the arms 21. Specifically, the flight control board 16 is the "brain" of the quadcopter 100, responsible for controlling various flight parameters such as flight attitude and altitude. The flight control board 16 is installed near the center of the fuselage 10 to ensure precise and balanced control of the motors 22 on each arm 21.
[0041] Please continue reading. Figure 5 The body 10 also includes a camera mounting bracket 17 and a camera 171. The camera mounting bracket 17 is located between two support columns 15 at the front end of the quadcopter 100 in the forward direction. The camera 171 is mounted on the camera mounting bracket 17. Specifically, placing the camera mounting bracket 17 between the battery fixing bracket 14 and the body base plate 11 helps to further reduce the size of the quadcopter 100.
[0042] Please continue reading. Figure 5 The fuselage 10 also includes a battery connector mount 18 and an antenna 19. The battery connector mount 18 is located between two support columns 15 at the rear end of the quadcopter 100 in the forward direction, and is connected to the battery 181 via a quick-connect connector. The antenna 19 is mounted on the battery connector mount 18 and is located at the rear end of the quadcopter 100 in the forward direction. Specifically, the battery connector mount 18 is positioned between the battery mounting bracket 14 and the fuselage base plate 11, resulting in a compact overall structure that helps to further reduce the size of the quadcopter 100. Simultaneously, the battery connector mount 18 transfers electricity from the battery 181 to the flight control board 16 via the quick-connect connector, and further to the arm 21. Additionally, the battery connector mount 18 further secures the antenna 19, contributing to the reduction in size.
[0043] Please see Figure 7The arm assembly 20 includes an arm 21, a motor 22, and a propeller 23. The arm 21 has a protrusion on the side near the fuselage 10. The motor 22 is detachably connected to the arm 21. The propeller 23 is located on the side of the motor 22 away from the arm 21. The motor 22 and the arm 21 are connected by hexagonal flathead screws.
[0044] Specifically, arm 21 is used to mount motor 22 and propeller 23, and is the direct mounting point for motor 22 and propeller 23. Motor 22 is fixed to the end of arm 21, providing power for the rotation of propeller 23. Propeller 23 generates lift under the drive of motor 22, enabling quadcopter 100 to take off and fly. The structural design of arm 21 needs to ensure that motor 22 is securely mounted and can withstand the centrifugal force and vibration generated by motor 22 and propeller 23 during high-speed rotation. Therefore, hexagonal flathead screws are used to connect motor 22 and arm 21 to ensure a good connection.
[0045] In addition, the arm 21 transmits the power generated by the motor 22 to the propeller 23, causing the propeller 23 to rotate and generate lift. Simultaneously, the lift generated by the propeller 23 is also transmitted back to the fuselage 10 via the arm 21, enabling the quadcopter 100 to perform takeoff, hovering, ascent, and descent. Furthermore, the arm 21 can distribute the weight of the propeller 23 and motor 22, as well as various forces generated during flight, to the fuselage 10, preventing excessive localized stress on the fuselage 10. Moreover, in the event of a collision or crash, the arm 21 typically contacts the ground or obstacle first, acting as a buffer to reduce direct impact on the fuselage 10 and critical internal equipment, thus protecting the safety of the entire aircraft.
[0046] In one embodiment, the arm 21 has a protrusion on the side near the body 10, which is designed to match the recessed area 121 on the quick-release plate 12, thereby fixing the arm 21 to the horizontal plane between the arm and the body 10. The hook-lock assembly 30 is used to fix the arm 21 to the vertical plane between the arm and the body 10, thereby achieving a better assembly effect between the arm assembly 20 and the body 10.
[0047] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
