[0050] Embodiment 1

[0051] This embodiment provides a quick-release structure for use in connecting the propeller 1 and the protective cover 2 of a drone, but is not limited thereto and can also be used in other devices to simplify the disassembly and assembly process of the two components and achieve quick disassembly and assembly.

[0052] like Figure 1 and Figure 2 As shown, the quick-release structure provided in this embodiment includes a first piece, a second piece and a lock structure. In this embodiment, the first piece is a propeller 1 and the second piece is a protective cover 2. Of course, when the first piece and the second piece are other parts, the quick-release structure is also within the protection scope of the present invention.

[0053] The propeller 1 is provided with a protrusion 151, and the protective cover 2 is provided with a slot 231. The protrusion 151 is provided along a first direction (such as Figure 2 The propeller 1 and the protective cover 2 are connected to or separated from the slot 231 in the direction of the arrow in the middle (as shown in the L direction), so that the propeller 1 and the protective cover 2 are connected to or separated from the slot 231 in the direction of the arrow in the middle (as shown in the L direction). Figure 2 After the protrusion 151 is inserted into the slot 231, it can limit the relative movement of the propeller 1 and the protective cover 2 in a direction perpendicular to the first direction, that is, the slot 231 and the insert can limit the relative movement of the propeller 1 and the protective cover 2 in the up and down directions and the front and rear directions (the direction perpendicular to the paper surface).

[0054] The locking mechanism 3 is arranged on the protective cover 2, and can be selectively inserted into the propeller 1, and the insertion direction of the locking mechanism 3 into the propeller 1 is set at an angle to the first direction. Since the insertion direction of the locking mechanism 3 is set at an angle to the first direction, after the locking mechanism 3 is inserted into the propeller 1, the movement of the protective cover 2 along the first direction can be restricted. By inserting the locking mechanism 3 into the propeller 1, and inserting the protrusion 151 of the propeller 1 into the groove 331 along the first direction, the relative movement of the protective cover 2 and the propeller 1 along six directions is restricted, that is, the protective cover 2 is fixed to the propeller 1, and the quick installation of the protective cover 2 is achieved. When the protective cover 2 needs to be removed, the locking mechanism 3 is separated from the propeller 1, and the protrusion 151 is separated from the groove 331 in the direction opposite to the first direction, so as to achieve the quick removal of the protective cover 2. The quick-release structure provided in this embodiment is simple and fast to assemble and disassemble.

[0055] Furthermore, the propeller 1 includes a motor 11, a rotating shaft 12, a blade 13 and an arm 14. The motor 11 is drivingly connected to the rotating shaft 12, the blade 13 is fixedly connected to the rotating shaft 12, and the connecting arm 21 is rotatably connected to the rotating shaft 12 through a bearing and other components. The arm 14 includes an arm body and a first arc portion 15, the first arc portion 15 is connected to one end of the arm body and encloses a circular hole, and the bearing is passed through the circular hole, so that the arm 14 is connected to the bearing.

[0056] The protective cover 2 includes a connecting arm 21, an arc-shaped protective rod 22, and a second arc portion 23. Both ends of the protective rod 22 are connected to the connecting arm 21, and the end of the connecting arm 21 that is not connected to the protective rod 22 is connected to the outer side of the second arc portion 23. The second arc portion 23 can be buckled on the outer circumferential surface of the first arc portion 15, wherein the protrusion 151 is provided on the first arc portion 15, and the slot 231 is provided on the second arc portion 23.

[0057] like Figure 2-Figure 5 As shown, in this embodiment, an annular groove 152 is provided on the outer periphery of the projection 151, and an annular protrusion 232 is provided on the outer periphery of the slot 231, and the annular protrusion 232 can be inserted into or out of the annular groove 152. The annular protrusion 232 and the annular groove 152 form a second plug-in barrier, further limiting the movement of the protective cover 2 and the propeller 1 in a direction perpendicular to the first direction.

[0058] Of course, in other embodiments, the propeller 1 may be provided with a slot 231, and the protective cover 2 may be provided with a protrusion 151. That is, the protrusion 151 is provided on the second arc portion 23, and the slot 231 is provided on the first arc portion 15. The groove wall of the slot 231 extends toward the side where the second arc portion 23 is located to form an annular protrusion 232; the protrusion 151 is provided on the second arc portion 23, and the second arc portion 23 is provided with an annular groove 152 that matches the annular protrusion 232.

[0059] Preferably, the locking mechanism 3 is disposed on the connecting arms 21 , wherein the locking mechanism 3 may be disposed on only one of the connecting arms 21 , or one locking mechanism 3 may be disposed on both connecting arms 21 .

[0060] In this embodiment, a locking mechanism 3 is disposed on each of the two connecting arms 21, and the slot 231 is located between the two locking mechanisms 3. The insertion directions of the two locking mechanisms 3 are arranged at an angle, and the insertion directions of the two locking mechanisms 3 are arranged at an angle to the first direction, thereby ensuring that after the propeller 1 and the protective cover 2 are fixed, the propeller 1 and the protective cover 2 will not separate along the first direction.

[0061] The two locking mechanisms 3 can make the distance between the second arc portion 23 and the first arc portion 15 consistent, thereby preventing the end of the second arc portion 23 from tilting downward.

[0062] like Figure 6-Figure 8 As shown, further, the lock mechanism 3 includes a fixing frame 31, a toggle key 32, a lock core 33 and an elastic member 34. The fixing frame 31 is fixed to the connecting arm 21 through a first connecting member 36, and a slideway 35 is provided on the fixing frame 31. The toggle key 32 is configured to slide on the slideway 35 so that the lock core 33 switches between a locking position for locking the propeller 1 and the protective cover 2 and an unlocking position for unlocking the propeller 1 and the protective cover 2. Specifically, the elastic member 34 can be a spring or a spring. In this embodiment, the elastic member 34 is a spring.

[0063] The lock core 33 is connected to the toggle key 32 via a second connecting member 37. The first connecting member 36 and the second connecting member 37 may be screws or other connecting members. Preferably, the connecting arm 21 is a hollow structure, the lock core 33 is located in the connecting arm 21, and can reciprocate relative to the connecting arm 21 along the length direction of the lock core 33, wherein the length direction of the lock core 33 is consistent with the insertion direction of the lock mechanism 3. In order to insert the lock core 33 into the propeller 1, a lock hole 153 is provided on the first arc portion 15 to allow the lock core 33 to pass through, and a keyhole is also provided on the second arc portion 23 to allow the lock core 33 to pass through. The toggle key 32 slides in the slideway 35, so that the lock core 33 penetrates the lock hole 153, and the lock core 33 is in a locked position to lock the propeller 1; and the lock core 33 is disengaged from the lock hole 153, and the lock core 33 is in an unlocked position to unlock the propeller 1.

[0064] In this embodiment, in order to realize the conversion of the lock core 33 between the locked position and the unlocked position, the slide 35 includes a first transverse slide 351 and a first longitudinal slide 352 which are arranged at an angle and connected to each other. Preferably, the slide 35 is an L-shaped structure, the length direction of the first longitudinal slide 352 is consistent with the insertion direction of the lock mechanism 3, and the first transverse slide 351 is located at one end of the first longitudinal slide 352 away from the second arc portion 23. A limiting protrusion is provided at the connection between the first transverse slide 351 and the first longitudinal slide 352 to limit the sliding of the toggle key 32 from the first transverse slide 351 to the first longitudinal slide 352.

[0065] One end of the elastic member 34 is fixedly connected to the fixing frame 31 or the connecting arm 21, and the other end is fixedly connected to the lock core 33. The elastic force of the elastic member 34 acts on the lock core 33, thereby keeping the lock core 33 in the locked position; in this embodiment, a groove 331 is provided at the rear end of the lock core 33, and the elastic member 34 is connected to the lock core 33 through the groove 331.

[0066] When the toggle key 32 is located in the first longitudinal slide 352, the elastic member 34 is in a compressed state, and the lock core 33 is subjected to the elastic force toward the second arc portion 23, so the elastic member 34 can keep the lock core 33 in the locked position for locking the propeller 1. When the toggle key 32 moves from the first longitudinal slide 352 to the end of the first transverse slide 351, the lock core 33 is separated from the lock hole 153, and the lock core 33 is in the unlocked position for unlocking the propeller 1. The lock core 33 can be rotatably connected to the fixing frame 31 or the connecting arm 21, the toggle key 32 moves along the first transverse slide 351, the lock core 33 rotates around its own axis, and the toggle key 32 abuts against the side wall or the limiting protrusion of the first transverse slide 351, thereby limiting the movement of the toggle key 32 in the slide 35, that is, ensuring that the lock core 33 is always in the unlocked position for unlocking the propeller 1. Or the lock core 33 can be slidably connected to the fixed frame 31 or the connecting arm 21, the toggle key 32 moves along the first horizontal slide 351, the movement trajectory of the lock core 33 and the toggle key 32 is the same, and the toggle key 32 abuts against the side wall or the limiting protrusion of the first horizontal slide 351, thereby limiting the movement of the toggle key 32 and the lock core 33.

[0067] This embodiment also provides an aircraft, which may be a drone. The aircraft includes the above-mentioned quick-release structure, thereby realizing the quick assembly and disassembly of the propeller 1 and the protective cover 2.

[0068] Embodiment 2

[0069] like Fig. 9 and Fig.10 As shown, the quick-release structure of the second embodiment is basically the same as that of the first embodiment, and the difference between the two is that the specific structures of the locking mechanism 3 and the slideway 35 are different.

[0070] The lock mechanism 3 includes a fixing frame 31, a toggle key 32 and a lock core 33. A lock plate 332 is provided at the end of the lock core 33. Preferably, the lock plate 332 is a rectangular parallelepiped structure, and the lock hole 153 provided on the first arc portion 15 is a waist-shaped hole. The lock core 33 reciprocates along its length direction, so that the lock plate 332 can be inserted into or out of the lock hole 153.

[0071] like Fig. 9 As shown, during the process of inserting or disengaging the lock plate 332, the lock core 33 is in the unlocking position for unlocking the propeller 1, and the lock plate 332 is in the first state, so that the lock plate 332 can pass through the lock hole 153. Fig.10 As shown, after the lock plate 332 is inserted into the lock hole 153, the lock core 33 can rotate 90°, the lock core 33 is in a locking position to lock the propeller 1, the lock plate 332 is in a second state, the length of the lock plate 332 is greater than the width of the lock hole 153, and the lock plate 332 abuts against the inner wall of the propeller 1, thereby limiting the lock plate 332 from detaching from the lock hole 153.

[0072] Furthermore, in order to realize the conversion of the lock core 33 between the locked position and the unlocked position, the slide 35 includes a second horizontal slide and a second vertical slide set at an angle. Preferably, the second horizontal slide and the second vertical slide are L-shaped, and the second horizontal slide is located at one end of the second vertical slide close to the second arc portion 23. The toggle key 32 slides in the second horizontal slide, which can make the lock core 33 rotate around its own axis. In order to enable the lock core 33 to rotate 90°, preferably, the second horizontal slide is an arc structure with an arc angle of 90°.

[0073] When the toggle key 32 is located at the second longitudinal slideway, the lock core 33 is at the unlocking position for unlocking the propeller 1, and the lock plate 332 is in the first state (eg Fig. 9 When the toggle key 32 slides from the second longitudinal slideway to the second transverse slideway, the lock plate 332 of the lock core 33 is inserted into the first arc portion 15 through the lock hole 153. The toggle key 32 is located in the second transverse slideway and slides along the second transverse slideway in a direction away from the second longitudinal slideway, so that the lock core 33 rotates 90° and the lock plate 332 is in the second state (as shown in FIG. Fig.10 As shown), the lock core 33 is in the locking position of the locking protection cover 2.

[0074] Embodiment 3

[0075] like Fig.11 As shown, the quick-release structure of the third embodiment is basically the same as that of the first embodiment, and the difference between the two is that the specific structure of the locking mechanism 3 is different.

[0076] At least one end of the second arc portion 23 is bent upward or downward along its axial direction to form a bent portion 233 (eg Fig.11The locking mechanism 3 includes a protrusion 38, which is arranged on the inner side of the curved portion 233. A bayonet 154 is arranged on the first arc portion 15. The curved portion 233 is configured to be deformed in a direction opposite to its bending direction so that the protrusion 38 and the bayonet 154 can be engaged with each other. When the protrusion 38 is inserted into the buckle, the curved portion 233 applies pressure to the first arc portion 15, thereby increasing the friction between the protrusion 38 and the side wall of the bayonet 154, increasing the connection strength between the bayonet 154 and the protrusion 38, and locking the propeller 1 with the protective cover 2. In order to enable the curved portion 233 to deform in a direction opposite to its bending direction, the second arc portion 23 is made of elastic material.

[0077] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
