Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles, and in particular to a gear-clamping quick-release device and a propeller blade for an unmanned aerial vehicle. Background Art

[0002] The propeller blades of a drone play an extremely important role in the entire drone system, but they are also a relatively easy-to-damage part. In order to ensure the safe flight of the drone and extend its service life, regular inspection and replacement of the propeller blades are necessary maintenance measures.

[0003] To facilitate the removal and maintenance of the propeller blades, traditional UAV propeller blades are mostly installed with springs inside the propeller seat. After long-term use, the elasticity of the spring decreases, causing the propeller blades to sometimes not stick tightly, affecting the stability of the UAV propeller blade structure and also affecting the removal speed. Summary of the invention

[0004] In order to improve the above-mentioned problems, the present application provides a gear clamping quick-release device and a drone blade.

[0005] The present application provides a gear clamping quick-release device and a drone propeller blade using the following technical solutions:

[0006] A gear clamping quick-release device, applied to drone blades, comprises a pressure plate body, a rotating member, a gear pin and a main body cover; the pressure plate body is provided with an adjusting hole, and a accommodating cavity is opened inside; the main body cover is connected to the pressure plate body and closes the accommodating cavity, and a plurality of pin fixing holes are opened on the main body cover; the rotating member is located in the accommodating cavity and below the adjusting hole, and a rotating hole is opened on the rotating member; a plurality of gear pins are provided, and correspond to the pin fixing holes one by one, one end of each is located in the accommodating cavity and meshes with the rotating member, and the other end passes through the pin fixing hole and extends away from the pressure plate body; a screw-tightening portion is provided at one end of the gear pin away from the rotating member; a disassembly tool passes through the adjusting hole and extends into the rotating hole, and the rotating member is rotated, and the rotating member synchronously rotates the gear pin so that the screw-tightening portion is screwed with the drone blade.

[0007] By adopting the above technical solution, the disassembly and assembly tool extends through the adjustment hole to the rotating hole. After the disassembly and assembly tool is stuck in the rotating hole, force is applied to the rotating part to rotate the rotating part. The rotating part is engaged with the gear pin shaft to synchronously drive all the gear pin shafts and the screw-tightening parts to rotate, so that all the screw-tightening parts are synchronously screwed to the UAV blades to achieve the effect of stable and quick installation. At the same time, multiple screw-tightening parts tighten the UAV blades at the same time, so that the stability of the connection is guaranteed. The disassembly and assembly tool rotates the rotating part in the opposite direction, and synchronously drives the gear pin shaft and the screw-tightening part to rotate in the opposite direction, so that all the screw-tightening parts can be synchronously separated from the UAV blades, thereby achieving the effect of quick disassembly.

[0008] Optionally, the main body cover is further provided with a fastening hole; the main body cover also includes a fixing piece, and the fixing piece passes through the fastening hole and is connected to the pressure plate body.

[0009] By adopting the above technical solution, the main body cover plate is connected to the pressure plate body by using the fixing piece to pass through the fastening hole, so that the main body cover plate and the pressure plate body can also be easily disassembled and assembled, making it easy to open the accommodating cavity for maintenance or replacement of internal parts.

[0010] Optionally, the gear pin is also sleeved with an adjusting washer.

[0011] By adopting the above technical solution, when the adjusting washer is sleeved on the gear pin shaft, it can prevent the gear pin shaft from loosening. For example, when the gear pin shaft is rotating, the adjusting washer can prevent it from loosening.

[0012] Optionally, the rotating hole has a prismatic hole wall.

[0013] By adopting the above technical solution, the prismatic hole wall can make the quick release tool abut against the prismatic hole wall when inserted therein, so that when the quick release tool rotates, it can more easily drive the rotating part to rotate through the rotating hole.

[0014] A drone blade comprises the quick-release device, a blade body and a driving body, wherein the blade body is located between the driving body and the quick-release device, and the quick-release device penetrates the blade body and is connected to the driving body.

[0015] By adopting the above technical solution, the blade body can be installed on the driving body using the quick release device. When disassembly is required, the blade body can also be disassembled from the driving body using the quick release device, thereby achieving the function of rapid installation and disassembly.

[0016] Optionally, the blade body is provided with a through hole, the driving body is provided with a threaded hole, and the screw-fastening portion passes through the through hole and is threadedly connected to the threaded hole.

[0017] By adopting the above technical solution, after the screw-fastening part passes through the through hole and is screwed into the threaded hole, the blade body is restricted on the screw-fastening part and the gear pin and cannot be separated, thereby ensuring the stable installation of the blade body.

[0018] Optionally, a plug-in hole is provided on the blade body, and a positioning column corresponding to the plug-in hole is provided at one end of the driving body close to the blade body.

[0019] By adopting the above technical solution, the blade body uses the insertion of the insertion hole and the positioning column to provide fixation of the position of the blade body and reduce deviation.

[0020] Optionally, the number of the threaded holes is plural, and the number of the threaded holes is greater than or equal to the number of the screw-fastening parts.

[0021] By adopting the above technical solution, the same number of threaded holes and the screw-fastening parts are screwed together to improve the stability of the installation. When the number of threaded holes is greater than the number of screw-fastening parts, the drive body can be adapted to different styles of blade bodies and quick-release devices, thereby improving the adaptability of the drive body.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The disassembly and assembly tool extends through the adjustment hole into the rotating hole. After the disassembly and assembly tool is stuck in the rotating hole, a force is applied to the rotating part to rotate the rotating part. The rotating part is meshed with the gear pin shaft to synchronously drive the rotation of several gear pin shafts and the screw-tightening parts, so that several screw-tightening parts are synchronously screwed to the UAV blades to achieve the effect of stable and fast installation. At the same time, several screw-tightening parts simultaneously tighten the UAV blades, so that the stability of the connection is guaranteed. The disassembly and assembly tool rotates the rotating part in the opposite direction, and synchronously drives the gear pin shaft and the screw-tightening parts to rotate in the opposite direction, so that all the screw-tightening parts can be synchronously separated from the UAV blades, thereby achieving the effect of quick disassembly;

[0024] 2.

[0038] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0039] The embodiments of the present application disclose a gear-clamping quick-release device and a UAV propeller blade.

[0040] A gear clamping quick-release device 3 is applied to a UAV blade and performs stable and convenient quick-release installation on the UAV blade.

[0041] refer to Figure 1 and Figure 2 As shown, it includes a pressure plate body 31, a rotating part 32, a gear pin shaft 33 and a main body cover plate 35; a positioning hole 311 is provided on the pressure plate body 31, and a accommodating cavity 312 is opened inside. The pressure plate body 31 can adopt a circular cover structure, so that there is a circular accommodating cavity 312 inside that can accommodate the rotating part 32 and the gear pin shaft 33, and the positioning hole 311 and the accommodating cavity 312 are in a connected state.

[0042] The main cover plate 35 is connected to the pressure plate body 31 . The main cover plate 35 mainly closes the cavity opening of the accommodating cavity 312 away from the adjustment hole 311 . A plurality of pin fixing holes 351 are provided on the main cover plate 35 for limiting the gear pin 33 .

[0043] The rotating member 32 is located in the accommodating cavity 312. The rotating member 32 is used to provide a linkage effect. The rotating member 32 can adopt a driving gear and is located below the adjusting hole 311. A rotating hole 321 is opened on the rotating member 32. The rotating hole 321 is located directly below the adjusting hole 311, so that an external quick-release tool can pass through the adjusting hole 311 and be inserted into the rotating hole 321. By clamping the rotating hole 321, the rotating member 32 is driven to rotate, providing a driving force for quick release or quick installation.

[0044] Among them, reference Figure 2 As shown, a pivot ring 353 is provided on the main cover plate 35, and a pivot groove 322 is provided on the rotating member 32. The pivot ring 353 is plugged into the pivot groove 322, and the rotating member 32 rotates along the pivot ring 353 through the pivot groove 322. The pivot ring 353 is used to provide a limit for the rotating member 32 to prevent the rotating member 32 from shifting in position during rotation.

[0045] There are several gear pins 33, the number of which is consistent with the number of pin fixing holes 351 and corresponds one to one. One end of the gear pin 33 is the gear end, which is located in the accommodating cavity 312 and meshes with the rotating member 32. When the rotating member 32 rotates, it can drive the gear pin 33 to rotate synchronously. The gear pin 33 is a rotating member 32 and is limited by the main cover plate 35 and cannot be separated from the accommodating cavity 312, thereby ensuring stability during rotation.

[0046] The other end of the gear pin 33 is a shaft end, which passes through the pin fixing hole 351 and extends away from the pressure plate body 31, and can extend to the UAV blade to be connected thereto.

[0047] Among them, in the present application, the number of gear pin shafts 33 and pin shaft fixing holes 351 are set to four for example. The specific number is determined according to the size of the accommodating cavity 312, the size of the gear pin shaft 33, and the size of the rotating part 32, and is not limited here.

[0048] A screw tightening portion 331 is provided at one end of the gear pin 33 away from the rotating member 32. The screw tightening portion 331 can be a screw rod. One end of the screw rod is provided with an external thread and the other end is connected to the gear pin 33, so that when the gear pin 33 is rotated by the rotating member 32, the screw rod is driven to rotate synchronously.

[0049] Specifically, the disassembly and assembly tool passes through the adjustment hole 311 and extends into the rotating hole 321. After the disassembly and assembly tool is stuck in the rotating hole 321, a force is applied to the rotating member 32 to rotate the rotating member 32. The rotating member 32 is engaged with the gear pin shaft 33 to synchronously drive all the gear pin shafts 33 and the screw-tightening parts 331 to rotate, so that all the screw-tightening parts 331 are synchronously screwed to the UAV blades to achieve the effect of stable and quick installation. At the same time, several screw-tightening parts 331 tighten the UAV blades at the same time, so that the stability of the connection is guaranteed.

[0050] The disassembly tool rotates the rotating member 32 in the opposite direction, and synchronously drives the gear pin 33 and the screw-tightening part 331 to rotate in the opposite direction, so that all the screw-tightening parts 331 can be synchronously separated from the drone blades, thereby achieving the effect of quick disassembly.

[0051] For further reference, Figure 1 and Figure 2 As shown, the main body cover 35 is also provided with fastening holes 352, and the number of fastening holes 352 can be set in multiple numbers. The main body cover 35 also includes fixing parts 36, and the number of fixing parts 36 is consistent with the number of fastening holes 352, and they correspond one to one. The present application takes four as an example. The fastening holes 352 and the pin fixing holes 351 are arranged at intervals so as not to interfere with the normal operation of the gear pin 33.

[0052] The fixing member 36 can be a screw, a fixing nail, etc. The fixing member 36 is connected to the pressure plate body 31 by passing through the fastening hole 352. The connection method can be screw connection or other connection methods. The main body cover 35 is not limited to being fixed on the pressure plate body 31 by other installation methods. The present application takes screw connection as an example. For example, a mounting block is set in the accommodating cavity 312 inside the pressure plate body 31, and a threaded mounting hole is opened on the mounting block. The fixing member 36 passes through the fastening hole 352 and is inserted into the threaded mounting hole and screwed. The fastening effect of multiple fixing members 36 is used to make the main body cover 35 fastened to the pressure plate body 31.

[0053] Specifically, the fixing member 36 is used to penetrate the fastening hole 352 to connect the main cover plate 35 with the pressure plate body 31, so that the main cover plate 35 and the pressure plate body 31 can also be easily disassembled and assembled, making it easy to open the accommodating cavity 312 to repair or replace internal components such as the gear pin 33, the rotating member 32, etc.

[0054] Furthermore, the gear pin 33 is also provided with an adjusting washer 34. When the adjusting washer 34 is provided on the gear pin 33, it can prevent the gear pin 33 from loosening. For example, when the gear pin 33 is rotating, the adjusting washer 34 can prevent it from loosening. At the same time, it can also play the role of adapting the pin fixing hole 351 and provide protection for the main body cover 35, thereby reducing the friction and damage caused by the contact between the gear pin 33 and the main body cover 35 during the rotation process.

[0055] Further, refer to Figure 3 As shown, the rotating hole 321 has a prismatic hole wall, which enables the quick release tool to abut against the prismatic hole wall when inserted therein, so that the quick release tool can more easily drive the rotating member 32 to rotate through the rotating hole 321 when rotating.

[0056] In addition to the prismatic hole wall, the rotating hole 321 can also be a straight hole, a cross hole, etc., so as to facilitate the adaptation of other quick-release tools such as a straight screwdriver and a cross screwdriver.

[0057] This application also provides a drone blade, reference Figure 4 As shown, it includes the gear clamping quick-release device 3 in the above embodiment, and also includes a blade body 1 and a driving body 2. The blade body 1 can adopt a single-blade or multi-blade structure, and the specific number of blades is not limited. The driving body 2 can adopt any required driving element such as a driving motor, a driving motor, etc., and the specific driving element is not limited.

[0058] The blade body 1 is located between the driving body 2 and the quick-release device 3, and the quick-release device 3 penetrates the blade body 1 and is connected to the driving body 2. The blade body 1 is installed on the driving body 2 using the quick-release device 3. When disassembly is required, the blade body 1 can also be removed from the driving body 2 using the quick-release device 3, thereby completing the function of rapid installation and disassembly.

[0059] For further reference, Figure 5 As shown, the blade body 1 is provided with a through hole 12, and the through hole 12 is for the screw-fastening part 331 and the gear pin shaft 33 to pass through. The driving body 2 is provided with a threaded hole 22, and the threaded hole 22 provides a screw connection for the screw-fastening part 331. When the screw-fastening part 331 passes through the through hole 12 and is screwed with the threaded hole 22, the blade body 1 is restricted on the screw-fastening part 331 and the gear pin shaft 33 and cannot be detached, thereby ensuring the stable installation of the blade body 1. When disassembly is required, the screw-fastening part 331 is rotated out of the threaded hole 22 and removed, and the screw-fastening part 331 and the gear pin shaft 33 are detached from the through hole 12 at the same time, and the quick disassembly is completed.

[0060] Furthermore, a plug-in hole 11 is provided on the blade body 1, and a positioning column 21 corresponding to the plug-in hole 11 is provided at one end of the driving body 2 close to the blade body 1. The blade body 1 utilizes the connection between the plug-in hole 11 and the positioning column 21 to provide a fixation of the position of the blade body 1 and reduce the offset. At the same time, after the blade body 1 is connected with the positioning column 21 through the plug-in hole 11, the through hole 12 can be aligned with the threaded hole 22 more quickly and accurately, thereby reducing the time required for fine-tuning and further increasing the work efficiency of quick disassembly or quick assembly.

[0061] Furthermore, the number of threaded holes 22 is set to be several, and the number of threaded holes 22 is greater than or equal to the number of screw-fastening parts 331. The number of threaded holes 22 and the number of screw-fastening parts 331 can be consistent, and when consistent, the threaded holes 22 and the screw-fastening parts 331 correspond one-to-one, so that when the screw-fastening part 331 is screwed with the threaded hole 22, the threaded hole 22 can be conveniently selected for screwing.

[0062] When the number of threaded holes 22 is inconsistent with the number of screw-fastening parts 331, the number of threaded holes 22 is greater than the number of screw-fastening parts 331, which can conveniently adapt to blade bodies 1 with different sizes and numbers of holes 12 or quick-release devices 3 with different numbers of screw-fastening parts 331, thereby improving the adaptability of the driving body 2.

[0063] Among them, the initial thread screwing angle of the screw-in portion 331 is consistent with that of the threaded hole 22, so that when the screw-in portion 331 is synchronously rotated by the rotating part 32 through the gear pin shaft 33, it can be synchronously screwed into the threaded hole 22 along the initial thread, or synchronously screwed out from the threaded hole 22, so as to achieve a more stable quick release or quick installation effect.

[0064] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
