The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] Please refer to Figures 1 - 5 , which shows a schematic diagram of a blade quick-release structure provided in an embodiment of the present utility model. The blade quick-release structure includes a blade seat assembly 100 provided on the motor and a locking assembly 200 provided on the blade seat assembly 100, where:

[0032] To connect the motor and the blade, a blade seat assembly 100 is provided on the motor. The blade seat assembly 100 includes a blade seat lower plate 120 provided on the motor and a blade seat upper plate 110 movably connected to the blade seat lower plate 120 through the locking assembly 200. The bottom of the blade seat lower plate 120 can be connected to the motor through fasteners such as bolts to provide support for the assembly of the blade. The blade seat lower plate 120 is a circular block-shaped base, which is provided with first clamping portions 121 oppositely along the circumference, and second clamping portions 123 symmetrically extending circularly towards the blade seat lower plate 120. The two first clamping portions 121 and the two second clamping portions 123 are arranged oppositely in pairs, and the first clamping portions 121 are arranged between the two second clamping portions 123.

[0033] To lock the upper paddle seat plate 110, a clamping boss 122 is provided on the first clamping portion 121, so that after the upper paddle seat plate 110 and the lower paddle seat plate 120 are rotationally clamped, it is used to lock the locking assembly 200 to prevent the upper paddle seat plate 110 and the lower paddle seat plate 120 from rotating relative to each other. It should be emphasized that for the purpose of anti-fooling, the clamping bosses 122 on the oppositely arranged first clamping portions 121 are not symmetrically arranged.

[0034] Furthermore, on one side of the upper paddle seat plate 110 close to the lower paddle seat plate 120, a strip-shaped accommodating portion 111 is provided which is arranged in imitation of the locking assembly 200. At the same time, clamping pins 112 symmetrically extend towards the lower paddle seat plate 120 on both sides of the accommodating portion 111 for clamping with the lower paddle seat plate 120. The paddle blade is arranged at one end of the upper paddle seat plate 110 far from the lower paddle seat plate 120.

[0035] Even further, the clamping pin 112 further includes a connecting portion 113 connected to the upper paddle seat plate 110 and a third clamping portion 114 provided on the connecting portion 113. The outer part of the third clamping portion 114 is set as an arc-shaped end face for cooperating with the second clamping portion 123 provided on the lower paddle seat plate 120. Since the second clamping portion 123 is a clamping edge extending from the circumference of the lower paddle seat plate 120, there is an arc edge left between the two second clamping portions 123, and the arc edge is arranged in imitation of the third clamping portion 114. When the upper paddle seat plate 110 and the lower paddle seat plate 120 are assembled, just align the third clamping portion 114 with the arc edge and move it downward until the third clamping portion 114 extends into the interior of the lower paddle seat plate 120, and then rotate the upper paddle seat plate 110 to align the third clamping portion 114 with the second clamping portion 123 to complete the clamping process.

[0036] To drive the upper plate 110 of the paddle seat to move up and down and rotate, the locking assembly 200 includes a connecting shaft 210 passing through the upper plate 110 of the paddle seat, and a locking plate 220 and a locking shaft member 230 respectively disposed at both ends of the connecting shaft 210. The locking plate 220 is disposed within the receiving portion 111 to be embedded in the upper plate 110 of the paddle seat. The connecting shaft 210 includes a first connecting tube 211 connected to the locking plate 220 and a second connecting tube 212 connected to the locking shaft member 230. The first connecting tube 211 passes through the upper plate 110 of the paddle seat, and the diameter of the first connecting tube 211 is greater than the diameter of the second connecting tube 212. A first fastener 410 is provided on the locking plate 220, which penetrates the locking plate 220 and is connected to the end of the first connecting tube 211. A second fastener 420 is provided on the locking shaft member 230. Since the second connecting tube 212 passes through the locking shaft member 230, the second fastener 420 is connected to the end of the second connecting tube 212. Therefore, when the locking shaft member 230 is controlled to rotate, since the locking plate 220 is clamped within the upper plate 110 of the paddle seat, the upper plate 110 of the paddle seat can rotate following the locking shaft member 230. At the same time, to avoid the accident of ejecting the paddle, the locking shaft member 230 can also be screwed to the upper plate 110 of the paddle seat to enhance the connection stability.

[0037] It should be noted that a lapping inclined surface 221 is provided on one side of the locking plate 220 close to the upper plate 110 of the paddle seat, and this inclined surface has the problems of anti-fooling and preventing the locking plate 220 from falling off. A clamping interface 222 for cooperating with the clamping boss 122 is provided on the side close to the lower plate 120 of the paddle seat. An elastic member 300 is further provided between the locking plate 220 and the upper plate 110 of the paddle seat, and the elastic member 300 is sleeved on the connecting shaft 210.

[0038] When assembling between the upper plate 110 and the lower plate 120 of the paddle seat, when the third clamping portion 114 is aligned with the arc edge and pressed down, the third clamping portion 114 extends into the lower plate 120 of the paddle seat. At this time, the locking shaft member 230 is rotated, thereby driving the upper plate 110 of the paddle seat to rotate, so that the second clamping portion 123 is clamped on the connecting portion 113. Since an elastic member 300 is provided between the locking plate 220 and the upper plate 110 of the paddle seat, and the elastic member 300 has a restoring function, one end thereof abuts against the top of the receiving portion 111, and the other end presses down the locking plate 220, so that the clamping interface 222 is engaged with the clamping boss 122 provided on the first clamping portion 121, thereby causing the locking plate 220 to be pressed and fitted into the lower plate 120 of the paddle seat, and thus the assembly is completed.

[0039] Similarly, when disassembly is required, the locking shaft member 230 is pulled upward, thereby driving the locking plate 220 to disengage from the clamping boss 122. At the same time, the locking shaft member 230 is rotated to drive the upper plate 110 of the paddle seat to rotate. When the third clamping portion 114 is aligned with the arc edge, the upper plate 110 of the paddle seat can be directly taken out.

[0040] In summary, a blade quick-release structure proposed according to the present utility model connects the lower plate of the blade seat to the motor. The locking shaft member drives the locking plate through the connecting shaft, and then drives the upper plate of the blade seat to rotate and be clamped to the lower plate of the blade seat. At the same time, the clamping structure between the locking plate and the lower plate of the blade seat prevents the upper plate of the blade seat from rotating when it is clamped to the lower plate of the blade seat, achieving the purpose of quick disassembly and assembly. Specifically, the blade seat assembly includes a lower plate of the blade seat provided on the motor and an upper plate of the blade seat movably connected to the lower plate of the blade seat through a locking assembly; the locking assembly includes a connecting shaft passing through the upper plate of the blade seat, locking plates respectively provided at both ends of the connecting shaft, and a locking shaft member. The locking plate is clamped to the upper plate of the blade seat, and the end of the locking plate away from the connecting shaft is clamped to the lower plate of the blade seat. The locking shaft member drives the upper plate of the blade seat and the locking plate to be pulled up along the axial direction of the connecting shaft, and at the same time drives the upper plate of the blade seat to rotate so that the upper plate of the blade seat and the lower plate of the blade seat are clamped. Release the locking shaft member so that the locking plate is clamped to the lower plate of the blade seat, thereby locking the upper plate and the lower plate of the blade seat.
