Detailed implementation manners

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0029] Please refer to Figure 1 , an embodiment of the present application provides a drone, including a drone body 10 and a locking and quick-release assembly 20. Among them, the drone body 10 includes a fuselage 11, arms 12, propellers 13, and a base 14. One end of the arm 12 is rotatably connected to the fuselage 11, and the opposite end is connected to the side of the base 14. A motor is provided inside the base 14, and the output shaft of the motor extends from the end face of the base 14 and is connected to the propeller 13 to drive the propeller 13 to rotate. When the propeller 13 rotates below the arm 12 and the length direction of the propeller 13 is substantially the same as the length direction of the arm 12, the folding of the propeller 13 is achieved. However, without being fixed, once the drone body 10 is slightly shaken or tilted, the arm 12 and the folded propeller 13 are likely to unfold or rotate by themselves, causing significant trouble to the operators. The locking and quick-release assembly 20 is provided on the base 14 of the drone body 10 to lock the arm 12 and the propeller 13 of the drone body 10 simultaneously.

[0030] Specifically, please refer to Figure 2 and Figure 3 , the locking and quick-release assembly 20 includes: a fixing member 30, the fixing member 30 includes a first fixing portion 31 and a second fixing portion 32 fixedly connected to the first fixing portion 31. A first accommodation groove 311 is provided on the side of the first fixing portion 31, and a second accommodation groove 321 communicating with the first accommodation groove 311 is provided on the side of the second fixing portion 32. The inner wall of the first accommodation groove 311 is used to wrap the side of the base 14, and a buckle 33 is provided at the notch of the first accommodation groove 311. The buckle 33 is used to be clamped with the side of the base 14 so that the first fixing portion 31 is fixed on the base 14. The inner wall of the second accommodation groove 321 is used to wrap the side of the folded propeller 13 to prevent the propeller 13 from rotating and unfolding.

[0031] During the installation process, the user can easily push the fixing member 30 directly into the predetermined position. By utilizing the elastic deformation of the buckle 33 on the first fixing portion 31 of the fixing member 30, the buckle 33 is tightly engaged with the side surface of the base 14, ensuring that the fixing member 30 is firmly fixed and does not fall off. After the fixing member 30 is installed on the base 14, its first fixing portion 31 wraps the side surface of the base 14, and the second fixing portion 32 wraps the side surface of the folded propeller 13. The first fixing portion 31 is fixed to the base 14 through the engagement of the buckle 33 with the side surface of the base 14. At this time, since the second fixing portion 32 is fixedly connected to the first fixing portion 31, the second fixing portion 32 is also fixed, thereby preventing the folded propeller 13 from rotating or unfolding relative to the base 14. Therefore, the above-mentioned fixing member 30 can lock the arm 12 of the drone body 10 and the folded propeller 13 simultaneously, thus preventing the folded propeller 13 from unfolding and rotating by itself during transportation, and significantly improving the convenience and efficiency of transporting the drone body 10. When disassembly is required, the operation is also simple and fast. The user only needs to push the buckle 33 slightly to disengage the buckle 33 from the base 14, and the fixing member 30 can be easily detached, achieving rapid disassembly, which greatly improves the operation efficiency and user experience.

[0032] In summary, through the design of the fixing member 30, the above-mentioned locking and quick-release assembly 20 can lock the arm 12 of the drone body 10 and the folded propeller 13 simultaneously, thus significantly improving the convenience and efficiency of transporting the drone body 10. While ensuring stability and safety, it also significantly optimizes the convenience of installation and disassembly. In addition, when the number of drone bodies 10 is multiple and the structural dimensions of the multiple bases 14 on each drone body 10 are the same, the fixing member 30 has strong versatility and a small volume, and can be mass-produced, thereby reducing the manufacturing cost.

[0033] Optionally, the buckle 33 includes a wrapping portion 331 and a disassembly portion 332. One end of the wrapping portion 331 is connected to the notch of the first accommodating groove 311, and the opposite end is connected to the disassembly portion 332. The disassembly portion 332 extends from the wrapping portion 331 in a direction away from the base 14. The wrapping portion 331 and the first accommodating groove 311 jointly wrap the base 14 along the circumferential direction of the base 14, and the circumferential wrapping length is greater than half of the circumference of the base 14.

[0034] The side surface of the base 14 is cylindrical. In order to wrap the side surface of the base 14, the inner walls of the first receiving groove 311 and the wrapping portion 331 are both arc-shaped. After the fixing member 30 is installed in place, the inner walls of the first receiving groove 311 and the wrapping portion 331 jointly wrap the side surface of the base 14 along the circumferential direction of the base 14, while the disassembly portion 332 is separated from the side surface of the base 14 and extends outward from the base 14. The wrapping length of the wrapping portion 331 of the buckle 33 and the first receiving groove 311 along the circumferential direction is greater than half of the circumference of the base 14, thereby forming a closing trend to tightly wrap the base 14 and making the connection between the fixing member 30 and the base 14 more stable. When disassembly is required, the user only needs to gently push the disassembly portion 332 in an obliquely outward direction, then the fixing member 30 can be separated from the base 14. In addition, the setting of the disassembly portion 332 also increases the opening size of the first fixing portion 31, enabling the buckle 33 to automatically deform and open after abutting against the side surface of the base 14, thereby enabling the user to more easily push the fixing member 30 into the predetermined position. Therefore, the setting of the disassembly portion 332 further improves the convenience of installation and disassembly of the fixing member 30.

[0035] Optionally, the number of buckles 33 is two, and the two buckles 33 are respectively arranged on two opposite edges of the notch of the first receiving groove 311.

[0036] The two buckles 33 are simultaneously clamped on the side surface of the base 14, making the connection between the fixing member 30 and the base 14 tighter and more stable, effectively preventing the fixing member 30 from accidentally falling off during handling and movement.

[0037] Furthermore, the two buckles 33 are symmetrically distributed along the radial direction of the base 14, so that the force on the fixing member 30 is more symmetrical.

[0038] Optionally, a limiting block 34 is provided on the inner wall of the first receiving groove 311. The limiting block 34 is used to cooperate with the limiting groove 141 on the base 14 to prevent the first fixing portion 31 from rotating relative to the base 14.

[0039] The limiting block 34 is embedded in the limiting groove 141 of the base 14, which can effectively prevent the fixing member 30 from rotating unnecessarily around the axis of the base 14. The limiting block 34 cooperates with the buckle 33, further enhancing the stability and safety of the locking and quick-release assembly 20 while ensuring quick installation and disassembly.

[0040] Exemplarily, the limiting block 34 is located on the inner end surface of the first fixing portion 31, and the limiting groove 141 on the base 14 is a card slot provided on the end cover of the base 14. The limiting block 34 is snapped into the card slot provided on the base 14 itself. By using the original structure of the base 14 to cooperate with the limiting block 34, the cost can be reduced.

[0041] Optionally, an avoidance groove 312 is provided on the inner wall of the first accommodation groove 311. The avoidance groove 312 is used to accommodate the protrusion 142 on the side surface of the base 14, so as to prevent interference between the first fixing portion 31 of the fixing member 30 and the protrusion 142 on the side surface of the base 14 during installation.

[0042] Optionally, please refer to Figure 3 and Figure 4 , the first fixing portion 31 has a fixing vertical surface 313 and two opposite fixing end surfaces 314. The two fixing end surfaces 314 are respectively connected to two opposite edges of the fixing vertical surface 313. The fixing vertical surface 313 and the two fixing end surfaces 314 enclose the first accommodation groove 311. The fixing vertical surface 313 is used to wrap the side surface of the base 14. One fixing end surface 314 is used to abut against one end surface of the base 14, and the other fixing end surface 314 is used to abut against the other end surface of the base 14 and is connected to the second fixing portion 32.

[0043] While wrapping the side surface of the base 14, the first fixing portion 31 also abuts against the two opposite end surfaces of the base 14, which can prevent the fixing member 30 from moving unnecessarily along the axial direction of the base 14, thereby further improving the stability and safety of the locking quick-release assembly 20.

[0044] Optionally, please refer to Figure 1 in combination, the second fixing portion 32 has a first limiting vertical surface 322 and two opposite second limiting vertical surfaces 323. The first edge of the first limiting vertical surface 322 is connected to the end surface of the first fixing portion 31. The two second limiting vertical surfaces 323 are respectively connected to the second edge and the third edge opposite to the first limiting vertical surface 322. The second edge and the third edge are respectively located at two opposite ends of the first edge. The first limiting vertical surface 322 and the two second limiting vertical surfaces 323 respectively abut against three side surfaces of the propeller 13.

[0045] The first limiting vertical surface 322 and the two second limiting vertical surfaces 323 are distributed in a U shape and respectively abut against three side surfaces of the propeller 13. The first limiting vertical surface 322 is used to prevent the propeller 13 from rotating, and the two second limiting vertical surfaces 323 are used to prevent the propeller 13 from unfolding. The cooperation of the first limiting vertical surface 322 and the two second limiting vertical surfaces 323 significantly enhances the stability of the propeller 13 during handling, movement, etc., effectively avoiding the occurrence of self-rotation and self-unfolding phenomena, thereby extending the service life of the UAV body 10 and improving the operation safety.

[0046] Optionally, the second fixing portion 32 further has a connecting surface 324, and the connecting surface 324 is connected to both the first limiting vertical surface 322 and the two second limiting vertical surfaces 323 at the same time.

[0047] The first limiting vertical surface 322, the two second limiting vertical surfaces 323 and the connecting surface 324 jointly enclose to form the second accommodating groove 321. The arrangement of the connecting surface 324 can improve the structural stability of the second fixing part 32, preventing it from deforming under the impact of the propeller 13 and thus losing the limiting effect on the propeller 13.

[0048] Furthermore, the connecting surface 324 abuts against the propeller 13 to prevent the fixing member 30 from moving along the axial direction of the base 14.

[0049] It should be noted that the propeller 13 may include at least two propeller bodies and a fixing component for fixing the at least two propeller bodies on the motor output shaft. The propeller body provides driving force for the drone body 10 by rotating. The first limiting vertical surface 322 and the second limiting vertical surface 323 may abut against the side surface of the propeller body or the side surface of the fixing component, as long as it can ensure that the propeller 13 will not rotate after folding. At the same time, the connecting surface 324 may also abut against the propeller body or the fixing component.

[0050] Optionally, please refer to Figure 1 and Figure 5 , the locking quick-release component 20 further includes a connecting belt 40. The number of the fixing members 30 is two. One end of the connecting belt 40 is connected to one fixing member 30, and the opposite end is connected to the other fixing member 30.

[0051] The locking quick-release component 20 includes two fixing members 30, which are connected by a connecting belt 40. This design forms a stable and flexible overall structure, which not only simplifies the assembly process and reduces costs, but also cleverly restricts the unnecessary movement of the arm 12, ensuring the stability of the locking quick-release component 20 during handling, and thus significantly improving the compactness and durability of the locking quick-release component 20. The quadcopter is a common form of the drone body 10, so generally two locking quick-release components 20 are used to fix the drone body 10 in practical applications. The two locking quick-release components 20 have a total of four fixing members 30 and two connecting belts 40, and the four fixing members 30 are respectively fixed on the four bases 14 of the drone body 10.

[0052] Furthermore, the connecting belt 40 is a leather belt.

[0053] The flexible design of the connecting belt 40 enhances the general compatibility of the fixing member 30 and effectively reduces the manufacturing cost. At the same time, the two fixing members 30 are flexibly connected by a leather belt, with strong adaptability. When disassembled, the two fixing members 30 can be wound or folded together by using the flexibility of the leather belt, which is convenient for storage and reduces the occupied space. After the drone body 10 is loaded into the box, the flexible leather belt can also avoid other items in the box.

[0054] Optionally, please refer to Figure 2 . The connecting belt 40 and the fixing member 30 are connected by bolts 51 and nuts 52. Specifically, a third receiving groove 315 is provided on the inner wall of the first receiving groove 311. The third receiving groove 315 is used to receive the nut 52. A first through hole 316 is provided at the bottom of the third receiving groove 315. The first through hole 316 corresponds to the threaded hole of the nut 52. A second through hole 41 is provided at the end of the connecting belt 40. After the bolt 51 passes through the second through hole 41 and the first through hole 316 in sequence, it is threadedly connected to the nut 52, thereby fixing the end of the belt on the fixing member 30.

[0055] In addition, the setting of the third receiving groove 315 can also cause the fixing member 30 to bulge outward to form a support platform 318. The support platform 318 provides a support plane for the installation of the connecting belt 40. The support plane is perpendicular to the axis of the bolt 51, so that the connecting belt 40 can be smoothly fixed on the fixing member 30.

[0056] Furthermore, the number of the third receiving grooves 315 on one fixing member 30 is two, and the two third receiving grooves 315 are symmetrically arranged. Both of the two third receiving grooves 315 can be used for the connection between the connecting belt 40 and the fixing member 30. In this way, the versatility of the fixing member 30 can be further improved and the cost can be reduced.

[0057] Optionally, a baffle 317 is provided in the third receiving groove 315. The baffle 317 divides the third receiving groove 315 into at least two sub-receiving grooves 3151. The at least two sub-receiving grooves 3151 are respectively used to receive the nuts 52. A first through hole 316 is provided at the bottom of each sub-receiving groove 3151. The number of the second through holes 41 on the belt is equal to and corresponds to the number of the first through holes 316 one by one. The end of the belt and the fixing member 30 are fixedly connected by at least two pairs of bolts 51 and nuts 52, which can improve the connection reliability and prevent the relative rotation between the belt and the fixing member 30.

[0058] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
