[0001] The embodiments of the utility model relate to the technical field of unmanned aerial vehicles (UAVs), and in particular to a blade structure and a UAV. Background Art

[0002] The propeller structure, the power actuator of a drone, typically consists of a propeller assembly and a base assembly. The propeller assembly is screwed to the base assembly, which is in turn fixed to the motor. As the propeller structure ages, it can become damaged and require replacement. Furthermore, during transportation, the propeller assembly takes up considerable space horizontally, potentially causing inconvenience, necessitating removal.

[0003] During the process of realizing the present invention, the inventors found that in order to ensure the firmness of the threaded connection between the blade assembly and the base assembly, multiple bolts are usually used to thread the blade assembly and the base assembly.

[0015] The beneficial effects of the embodiment of the present invention are as follows: Different from the prior art, the embodiment of the present invention modularizes the blade structure and divides the blade structure into a blade assembly and a base assembly. The blade assembly includes a blade member, a guide slide, a limit member and an elastic member. The blade member is provided with a first abutment structure. The guide slide is connected to the blade member. The limit member is sleeved on the guide slide. The limit member can slide along the guide slide but cannot rotate relative to the guide slide. The two ends of the elastic member are respectively connected to the blade member and the limit member. The base assembly includes a base, a paddle seat and a driving member. The paddle seat is fixed to the base. The paddle seat is provided with a second abutment structure and a first limit groove. The driving member is movably arranged on the base.

[0016] When the blade assembly needs to be installed on the base assembly, the first abutting structure and the second abutting structure are first misaligned, and then the blade assembly is pressed toward the base assembly, and the limiting member abuts against the paddle seat. At this time, the elastic member is compressed by force until the first abutting structure exceeds the second abutting structure. Then, the blade assembly is rotated until the first abutting structure and the second abutting structure at least partially overlap, and the limiting member is rotated to a position where the first limiting groove is aligned. At this time, the elastic member stretches and pushes the limiting member to snap into the first limiting groove. The first abutting structure abuts against the second abutting structure, limiting the separation of the blade assembly and the base assembly. The limiting member and the first limiting groove limit the rotation of the blade assembly relative to the base assembly, thereby achieving fixation between the blade assembly and the base assembly.

[0017] When it is necessary to separate the blade assembly and the base assembly, the driving member is driven so that the driving member forces the limiting member to slide along the guide member toward the blade member until the limiting member disengages from the first limiting groove, and then the blade assembly is rotated in the opposite direction until the first abutment structure and the second abutment structure are misaligned. At this time, the blade assembly and the base assembly are in an unlocked state, and the blade assembly and the base assembly can move away from each other.

[0018] In short, by controlling the movement of the blade assembly toward the base assembly and then controlling the rotation of the blade assembly, the blade assembly and the base assembly can be fixed to each other. In addition, by controlling the driving member and then rotating the blade assembly in the opposite direction, the blade assembly and the base assembly can be unlocked. There is no need to use external tools to tighten the bolts, and the disassembly and assembly operations are simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0041] See also Figure 1 The blade structure 1000 includes a blade assembly 1 and a base assembly 3. The base assembly 3 is mounted on the rotating portion of the motor 2000 (not shown), and the blade assembly 1 and the base assembly 3 are detachably connected. The blade structure 1000 has two states: a locked state and an unlocked state. In the locked state, the blade assembly 1 and the base assembly 3 are fixedly connected; in the unlocked state, the blade assembly 1 and the base assembly 3 can be separated by moving them away from each other.

[0042] For the blade assembly 1 above, see Figure 2 The blade assembly 1 includes a blade member 11, a guide slide 14, a limit member 13 and an elastic member 12. The guide slide 14 is arranged on the blade member 11, and the limit member 13 is slidably arranged on the guide slide 14. The limit member 13 can slide along the guide slide 14. One end of the elastic member 12 is connected to the blade member 11, and the other end of the elastic member 12 is connected to the limit member 13. The limit member 13 is used to be detachably connected to the base assembly 3. When the limit member 13 is fixedly connected to the base assembly 3, the limit member 13 and the base assembly 3 remain in a fixed state, reducing the risk of the limit member 13 and the base assembly 3 being detached. When the elastic force of the elastic member 12 is overcome to separate the limit member 13 from the base assembly 3, the blade assembly 1 and the base assembly 3 can be separated from each other, which facilitates the disassembly of the blade assembly 1.

[0043] For the above-mentioned blade member 11, please refer to Figure 2-4The paddle member 11 includes a clamping member 111, a paddle blade 112, a blade seat 113, and a first threaded member. A positioning hole 1122 and a plurality of first through holes 1121 are formed on the paddle blade 112. The positioning hole 1122 and each first through hole 1121 are approximately located in the middle of the paddle blade 112, and each first through hole 1121 is arranged around the positioning hole 1122. A positioning post 1131 and a plurality of second screw holes 1132 are provided on the top surface of the blade seat 113. The positioning post 1131 and each second screw hole 1132 are approximately arranged at the center of the top surface of the blade seat 113, and each second screw hole 1132 is arranged around the positioning post 1131. A receiving hole 1112 and a plurality of second through holes 1111 are formed on the clamping member 111. The receiving hole 1112 and each second through hole 1111 are approximately located at the center of the clamping member 111, and each second through hole 1111 is arranged around the receiving hole 1112. The paddle blade 112 is located between the blade seat 113 and the clamping member 111. The positioning post 1131 of the blade seat 113 passes through the positioning hole 1122 and is inserted into the receiving hole 1112. The first through hole 1121, the second through hole 1111, and the second screw hole 1132 correspond one to one. A first threaded member passes through a second through hole 1111 and a first through hole 1121 in sequence and is screwed into a second screw hole 1132 to fix the paddle blade 112 and the blade seat 113. The paddle blade 112 and the blade seat 113 are fixed in a detachable manner. When a component of the paddle blade 112 and the blade seat 113 is damaged, one of the components can be disassembled and replaced without replacing the entire paddle member 11, which helps to reduce the cost of subsequent maintenance.

[0044] It is understandable that, in some embodiments, the paddle blade 112 and the blade seat 113 may not be fixed in a detachable manner, for example, the paddle blade 112 and the blade seat 113 may be integrally formed.

[0045] The blade seat 113 is located at one end away from the blade 112, i.e., the bottom of the blade seat 113. The blade seat 113 forms an inner cavity with an opening at the bottom. The blade seat 113 is provided with a first abutment structure 1134 on the side wall of the inner cavity. The guide slide 14 includes a guide slide portion 141 and a limiting portion 142. One end of the guide slide portion 141 is fixed to the top wall of the blade seat 113 in the inner cavity. The limiting portion 142 is provided at the other end of the guide slide portion 141, and the limiting portion 142 protrudes from the side wall of the guide slide portion 141. The shape of the limiting portion 13 can be a straight line, a cross, a Y-shape, etc., and those skilled in the art can also set it to other shapes according to actual needs. The limiting portion 13 is provided with a third connecting hole 132, the size of which matches the size of the guide slide portion 141. The guide portion 141 is provided through the third connection hole 132, so that the limiter 13 is sleeved between the limiter 142 and the top inner wall of the blade seat 113, and the limiter 13 can slide along the guide portion 141. The elastic member 12 is sleeved on the guide portion 141 and arranged between the limiter 13 and the top wall of the inner cavity of the blade seat 113. The elastic member 12 is set in a compressed state so that the elastic member 12 continuously applies a force to the limiter 13 toward the limiter 142, so that the limiter 13 always maintains a tendency to move toward the base assembly 3.

[0046] It should be noted that: when the limiting member 13 is slidably sleeved on the guide slide 14, the limiting member 13 is allowed to slide along the guide slide 14, but the limiting member 13 is restricted from rotating relative to the guide slide 14, and a second limiting groove 1135 is provided on the inner top wall of the inner cavity, and the depth of the second limiting groove 1135 is not less than the height of the limiting member 13, the limiting member 13 can be accommodated in the second limiting groove 1135, and the limiting member 13 can slide in the second limiting groove 1135, and when the limiting member 13 abuts against the limiting portion 142, the limiting member 13 will also keep a part of it in the second limiting groove 1135, and the other part of the limiting member 13 is exposed from the second limiting groove 1135, so as to pass through the second limiting groove 1135 The rotation of the limit member 13 relative to the guide slide 14 is limited; or, the wall surface of the third connecting hole 132 is provided with a first limit plane, and the side wall of the guide slide 141 is provided with a second limit plane. When the limit member 13 is sleeved on the guide slide 141, the second limit plane and the first limit plane are fitted together, allowing the limit member 13 to slide along the guide slide 141, but limiting the rotation of the limit member 13 relative to the guide slide 141. Of course, there can also be multiple planes between the limit member 13 and the guide slide 14 that limit the relative rotation, so that the cross-section of the guide slide 141 and the cross-section of the limit member 13 are polygonal. For example, the cross-sectional shapes of the guide slide 141 and the limit member 13 can be triangular, quadrilateral, cross-shaped, etc.

[0047] In some embodiments, the guide sliding member 14 and the blade seat 113 can be fixed by screwing, for example: the guide sliding member 14 is set as a bolt, or an external thread is provided at the end of the guide sliding portion 141 away from the limiting portion 142, and a third screw hole 1133 is provided at the center of the top wall of the inner cavity of the blade seat 113, and the guide sliding member 14 is screwed to the third screw hole 1133.

[0048] For base assembly 3 above, see Figure 5 and Figure 6 The base assembly 3 includes a paddle seat 31, a driving member 32, a cover plate 33, a base 34, and a second threaded member. The second threaded member is sequentially inserted into the cover plate 33 and the driving member 32 and is screwed to the paddle seat 31. The driving member 32 and the cover plate 33 are clamped between the paddle seat 31 and the base 34. The paddle seat 31, the driving member 32, and the cover plate 33 are mounted on the base 34 by bolts, and the driving member 32 can also move relative to the paddle seat 31 and the cover plate 33. The paddle seat 31 is used to engage with the limiting member 13 of the blade assembly 1 to achieve fixation of the base assembly 3 and the blade assembly 1. The driving member 32 is used to drive the limiting member 13 of the blade assembly 1 and the paddle seat 31 to separate when driven by an external force, thereby releasing the fixation between the paddle seat 31 and the blade assembly 1.

[0049] For the paddle seat 31 mentioned above, see Figure 5 The outer edge of the paddle seat 31 is provided with a second abutment structure 315. The top surface of the paddle seat 31 is provided with a first limiting groove 311, which matches the limiting member 13. The center of the paddle seat 31 is provided with a first connecting hole 312, which communicates with the first limiting groove 311. The driving member 32 includes a driving portion 321, which is inserted into the first connecting hole 312.

[0050] For ease of understanding, the following describes the installation and disassembly processes of the blade assembly 1 and the base assembly 3:

[0051] 1) Installation process: first stagger the second abutment structure 315 and the first abutment structure 1134, then push the blade assembly 1 toward the base assembly 3, the limiting member 13 is abutted by the paddle seat 31, and the limiting member 13 slides along the guide sliding portion 141 toward the direction of the paddle blade 112, compressing the elastic member 12, and then control the blade assembly 1 to rotate relative to the base assembly 3 until the second abutment structure 315 and the first abutment structure 1134 are aligned, remove the external force, and the first abutment structure 1134 abuts against the second abutment structure 315. At this time, the limiting member 13 rotates to correspond to the first limiting groove 311, the elastic member 12 extends, and drives the limiting member 13 to be inserted into the first limiting groove 311, thereby achieving locking between the blade assembly 1 and the base assembly 3.

[0052] 2) Disassembly process: First, drive the driving member 32, the driving member 32 abuts the limiting member 13, and forces the limiting member 13 to move toward the blade assembly 1 until the limiting member 13 disengages from the first limiting groove 311. At this time, the blade assembly 1 can rotate relative to the base assembly 3; then control the blade assembly 1 to rotate relative to the base assembly 3 until the second abutting structure 315 and the first abutting structure 1134 are staggered. At this time, the blade assembly 1 and the base assembly 3 are in an unlocked state.

[0053] It can be seen from the installation and disassembly processes of the blade assembly 1 and the base assembly 3 that by controlling the blade assembly 1 to move toward the base assembly 3 and then controlling the rotation of the blade assembly 1, the blade assembly 1 and the base assembly 3 can be fixed to each other, and by controlling the driving member 32 and then rotating the blade assembly 1 in the opposite direction, the blade assembly 1 and the base assembly 3 can be unlocked. There is no need to use external tools to tighten the bolts, and the disassembly and assembly operations are simple and convenient.

[0054] It is understandable that, in the locked state, the axial projection of the limiting member 13 along the first connecting hole 312 is at least partially located within the first connecting hole 312 , so that the driving member 32 can drive the limiting member 13 to move toward the blade assembly 1 .

[0055] In some embodiments, when the first limiting groove 311 restricts the rotation of the limiting member 13 relative to the paddle seat 31, the depth of the first limiting groove 311 is equal to the height at which the limiting member 13 emerges from the second limiting groove 1135 in the locked state. This configuration prevents the first limiting groove 311 from being too deep, thereby not only improving the structural strength of the paddle seat 31 but also reducing the thickness of the paddle seat 31, making the blade structure 1000 more compact. Furthermore, the first limiting groove 311 is prevented from being too shallow, thereby preventing a gap from forming between the blade seat 113 and the paddle seat 31 in the locked state, making the blade structure 1000 more compact and improving its structural strength.

[0056] In some embodiments, there are multiple second abutment structures 315 and first abutment structures 1134, for example, 3, 4, 5, etc. The second abutment structures 315 are evenly spaced along the circumference of the paddle seat 31. The second abutment structures 315 are formed as latching teeth extending outward from the outer edge of the paddle seat 31. The first abutment structures 1134 are spaced apart on the inner sidewall of the blade seat 113, and the first abutment structures 1134 are evenly spaced along the circumference of the inner sidewall of the blade seat 113. A first sliding channel is formed between two adjacent first abutment structures 1134, and a second sliding channel is formed between two adjacent second abutment structures 315. When the blade assembly 1 is assembled to the base assembly 3, each second abutment structure 315 is aligned with each first sliding channel, and each first abutment structure 1134 is aligned with the second sliding channel, and then external force is applied to make the blade seat 113 close to the paddle seat 31 until the second abutment structure 315 exceeds the first abutment structure 1134, and then the blade assembly 1 is rotated until the limiting member 13 is aligned with the first limiting groove 311, and the second abutment structure 315 is aligned one by one with the first abutment structure 1134. At this time, the external force is removed, and under the action of the elastic member 12, the limiting member 13 is stuck in the first limiting groove 311, limiting the mutual rotation between the blade assembly 1 and the base assembly 3, and at this time the second abutment structure 315 abuts against the first abutment structure 1134, limiting the mutual distance between the blade assembly 1 and the base assembly 3, completing the fixation between the blade assembly 1 and the base assembly 3. When separating the blade assembly 1 from the base assembly 3, drive the driving member 32 to move the limiting member 13 toward the blade seat 113 until the limiting member 13 disengages from the first limiting groove 311 and the first abutment structure 1134 separates from the second abutment structure 315, then rotate the blade assembly 1 until the second abutment structure 315 is aligned with the sliding channel, which is now in an unlocked state, and finally move away from the blade assembly 1 and the base assembly 3 until the second abutment structure 315 is withdrawn from the inner cavity of the blade seat 113, completing the separation of the blade assembly 1 and the base assembly 3.

[0057] In some embodiments, the first abutment structure 1134 can be configured as a baffle extending inwardly from the inner sidewall of the blade seat 113. Furthermore, both sides of the baffle can extend toward the top to form side panels. Thus, when the latch abuts against the baffle, the side panels can restrict the rotation of the latch, thereby limiting the relative rotation between the blade seat 113 and the paddle seat 31.

[0058] In some embodiments, the top surface of the paddle seat 31 is provided with four grooves 313, each groove 313 being evenly distributed along the circumference of the paddle seat 31. A second connection hole 314 is provided at the bottom of the groove 313, and four first screw holes 341 are provided on the base 34. Bolts are sequentially inserted through the grooves 313, the second connection holes 314, the drive portion 321, and the cover plate 33, and are screwed into the first screw holes 341. The cover plate 33 can be configured in a cross shape to avoid interference with the bolts. The provision of the grooves 313 can prevent the head of the bolt from being higher than the top surface of the paddle seat 31, thereby preventing the head of the bolt from obstructing the rotation of the limit member 13 relative to the paddle seat 31.

[0059] For the above-mentioned drive member 32, see Figure 5 The driving member 32 also includes a disk portion 322 and an operating portion 323. The disk portion 322 is arranged in a ring shape, the driving portion 321 is arranged at the center of the disk portion 322, and the operating portion 323 is arranged on the outside of the disk portion 322. The driving portion 321 and the disk portion 322 are connected by a plurality of connecting rods 324, and the space enclosed by the driving portion 321, the connecting rods 324 and the disk portion 322 is used for the bolt to pass through. The connecting rod 324 extends toward the outside of the disk portion 322 and is connected to the operating portion 323. A plurality of operating portions 323 can be provided so that the operator can conveniently operate the driving member 32 at multiple angles. Each connecting rod 324 and each operating portion 323 are evenly arranged along the circumference of the disk portion 322 to enhance the structural strength of the driving member 32.

[0060] The center of the driving portion 321 is provided with an escape hole 3211 for accommodating the guide member 14. In the locked state, the guide member 14 is inserted into the escape hole 3211. This prevents a gap from forming between the blade seat 113 and the paddle seat 31, making the blade structure 1000 more compact and improving the structural strength of the blade structure 1000.

[0061] In some embodiments, the driving portion 321 is provided with a first guide slope. In the locked state, the stopper 13 abuts against the first guide slope. When the driving member 32 rotates, the first guide slope can force the driving member 32 to move toward the blade seat 113.

[0062] Furthermore, the limiting member 13 is provided with a second guiding bevel 131 that matches the first guiding bevel. In the locked state, the second guiding bevel 131 is in contact with the first guiding bevel. Through such a setting, the movement of the limiting member 13 when it is separated from the first limiting groove 311 is smoother, avoiding jamming. The top and bottom of the limiting member 13 are both provided with the second guiding bevel 131, so that when installed, the top and bottom of the limiting member 13 can be installed toward the paddle seat 31, which is convenient for assembly. It can be understood that in the locked state, the projection of the second guiding bevel 131 along the axial direction of the first connecting hole 312 is at least partially located within the first connecting hole 312.

[0063] In some embodiments, a gap is provided between the cover plate 33 and the paddle seat 31 to allow the driver 32 to move axially along the second connection hole 314. In the locked state, the driver 321 abuts against the stopper. By driving the driver 321 toward the blade seat 113, the stopper 13 is forced to move toward the blade seat 113, thereby disengaging the stopper 13 from the first stopper slot 311.

[0064] In the embodiment of the present invention, the blade structure 1000 is modularly designed and divided into a blade assembly 1 and a base assembly 3. The blade assembly 1 includes a blade member 11, an elastic member 12, a limiting member 13, and a guide slide 14. The blade member 11 is provided with a first abutting structure 1134. The guide slide 14 is connected to the blade member 11. The limiting member 13 is sleeved on the guide slide 14. The limiting member 13 can slide along the guide slide 14 but cannot rotate relative to the guide slide 14. The two ends of the elastic member 12 are respectively connected to the blade member 11 and the limiting member 13. The base assembly 3 includes a paddle seat 31, a driving member 32, and a base 34. The paddle seat 31 is fixed to the base 34. The paddle seat 31 is provided with a second abutting structure 315 and a first limiting groove 311. The driving member 32 is movably provided on the base 34.

[0065] When the blade assembly 1 needs to be installed on the base assembly 3, the first abutting structure 1134 and the second abutting structure 315 are first misaligned, and then the blade assembly 1 is pressed toward the base assembly 3, and the limiting member 13 abuts against the paddle seat 31. At this time, the elastic member 12 is compressed until the first abutting structure 1134 exceeds the second abutting structure 315. Then, the blade assembly 1 is rotated until the first abutting structure 1134 and the second abutting structure 315 at least partially overlap, and the limiting member 13 is rotated to a position where the first limiting groove 311 is aligned. At this time, the elastic member 12 extends, pushing the limiting member 13 to fit into the first limiting groove 311, and the first abutting structure 1134 abuts against the second abutting structure 315, limiting the separation of the blade assembly 1 and the base assembly 3. The limiting member 13 and the first limiting groove 311 limit the rotation of the blade assembly 1 relative to the base assembly 3, thereby achieving fixation between the blade assembly 1 and the base assembly 3.

[0066] When it is necessary to separate the blade assembly 1 and the base assembly 3, the driving member 32 is driven so that the driving member 32 forces the limiting member 13 to slide along the guide member 14 toward the blade member 11 until the limiting member 13 disengages from the first limiting groove 311, and then the blade assembly 1 is rotated in the opposite direction until the first abutment structure 1134 and the second abutment structure 315 are misaligned. At this time, the blade assembly 1 and the base assembly 3 are in an unlocked state, and the blade assembly 1 and the base assembly 3 can move away from each other.
