Description

Technical Field

[0001] This utility model belongs to the technical field of drones, and specifically relates to a structure for disassembling and assembling the propeller blades of a drone. Background Art

[0002] A drone, short for an unmanned aerial vehicle, is an unpiloted aircraft controlled by radio remote control equipment and a self - contained program control device. From a technical perspective, it can be classified into: unmanned fixed - wing aircraft, unmanned vertical take - off and landing aircraft, unmanned airships, unmanned helicopters, rotary - wing drones, unmanned parafoil aircraft, etc. Among them, rotary - wing drones are widely used in various fields due to their small size and lower price. Common rotary - wing drones include quad - rotor, hex - rotor, and octo - rotor types. The main structure of the rotor part includes motors and propeller blades.

[0003] However, in the prior art, the common connection method between the rotor and the propeller blade of a drone is to pass the propeller blade through a screw rod and install a reverse nut on it to lock the propeller blade. However, this structure brings great inconvenience to the users of the drone because when installing and disassembling the propeller blades, each propeller blade needs to be passed through and the nut tightened one by one. For a multi - rotor drone, it takes a lot of time, thus wasting a large amount of time and energy. Content of the Utility Model

[0004] The purpose of this utility model is to provide a structure for disassembling and assembling the propeller blades of a drone, which can disassemble and assemble the propeller blades of the drone faster, without a particularly cumbersome operation process, is simple to operate, does not require spending a large amount of time and energy for disassembly and assembly, and thus can effectively improve work efficiency.

[0005] The technical solution adopted by this utility model is specifically as follows:

[0006] A structure for disassembling and assembling the propeller blades of a drone includes a motor. Above the motor is a fixed block. Inside the fixed block is a control device. Above the fixed block is a rotating block. Above the rotating block is a connecting block. At both ends of the connecting block are respectively provided with propeller blades.

[0007] Among them, the control device includes a control rod and an L - shaped limiting block. The control rod is used to control the rotation of the L - shaped limiting block.

[0008] As one of the preferred embodiments of this utility model, the control device includes a control disk. One end of the control rod is fixedly connected to the outside of the control disk. Two groups of L - shaped limiting blocks are respectively arranged at both ends above the control disk, and the L - shaped limiting blocks are fixedly connected to the control disk. At both ends below the control disk are respectively fixedly connected with control blocks. On one side of the center symmetry of the two groups of control blocks are respectively fixedly connected with return springs. The other end of the return spring is fixedly connected with a pressing block.

[0009] In one of the preferred embodiments of the present utility model, positioning blocks are fixedly connected to both sides of the lower end of the rotating block. The two L-shaped limiting blocks are designed to be centrosymmetric, and the positioning blocks are matched with the L-shaped limiting blocks.

[0010] In one of the preferred embodiments of the present utility model, an annular rail groove is formed inside the lower end of the fixed block. The two extrusion blocks are respectively arranged in the annular rail groove and are fixedly connected to the fixed block. The lower end of the annular rail groove is matched with the control disc, the upper end of the annular rail groove is matched with the rotation trajectory of the L-shaped limiting block, and a track through hole is formed on one side of the annular rail groove and is matched with the control rod.

[0011] In one of the preferred embodiments of the present utility model, a groove is formed at the upper end of the fixed block, and rectangular grooves are respectively formed on both sides of the groove formed in the fixed block. The rectangular grooves are arranged at the upper end of the annular rail groove and are matched with the positioning blocks.

[0012] The technical effects achieved by the present utility model are as follows:

[0013] The blade disassembly and assembly structure of the unmanned aerial vehicle of the present utility model can quickly disassemble and assemble the propeller blades of the unmanned aerial vehicle. By controlling the control component, the control rod in the control component rotates, thereby driving the control disc at the other end of the control rod to rotate, driving the control block below the control disc to rotate, thereby squeezing the return spring. The L-shaped limiting block above the control disc can move. At this time, the rotating block and the positioning block are placed into the groove and the rectangular groove formed in the fixed block, so that the positioning block can be quickly disassembled and assembled. There is no particularly cumbersome operation process, the operation is simple, and it does not require a lot of time and energy to disassemble and assemble it, thereby effectively improving the work efficiency.

[0022] In order to make the purpose and advantages of the present utility model clearer, the following specific description of the present utility model is given in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0023] As Figure 1 and Figure 2 shown, a structure for disassembling and assembling propeller blades of a drone includes a motor 1, a fixed block 2 is arranged above the motor 1, a control device 3 is arranged inside the fixed block 2, a rotating block 4 is arranged above the fixed block 2, a connecting block 5 is arranged above the rotating block 4, and propeller blades 6 are respectively arranged at both ends of the connecting block 5;

[0024] Among them, the control device 3 includes a control rod 301 and an L-shaped limit block 305, and the control rod 301 is used to control the rotation of the L-shaped limit block 305.

[0025] In this embodiment, when preparing to disassemble the drone propeller blade 6, the control lever 301 in the control device 3 is rotated, so that the control lever 301 rotates within the track through-hole 203, causing the control disk 302 at the other end of the control lever 301 to rotate at the lower end of the annular track groove 201. Due to the rotation of the control disk 302, the two groups of L-shaped limit blocks 305 above the turntable rotate at the upper end of the annular track groove 201, moving away from above the positioning block 401. At the same time, as the control disk 302 rotates, the two groups of control blocks 303 below the control disk 302 rotate, thereby stretching the return spring 304. At this time, the rotating block 4 is moved upward out of the groove opened in the fixed block 2, so that the positioning blocks 401 at both ends below the rotating block 4 move upward along the rectangular groove 204. After releasing the control lever 301, under the action of the return spring 304, the control device 3 can return to its initial state, enabling the quick disassembly of the connecting block 5 and the propeller blade 6; when preparing to install the drone propeller blade 6, just repeat the above process. And when the L-shaped limit block 305 rotates, just install the rotating block 4 in the groove opened in the fixed block 2, and install the positioning block 401 in the rectangular groove 204, then release the control lever 301. Under the elastic function of the return spring 304, the control device 3 can return to its initial state, and the L-shaped limit block 305 can limit and fix the positioning block 401, enabling the fixed installation of the connecting block 5 and the propeller blade 6, thus completing a series of operations.

[0026] As Figure 4 and Figure 6 shown, the control device 3 includes a control disk 302. The outer side of the control disk 302 is fixedly connected to one end of the control lever 301. Two groups of L-shaped limit blocks 305 are respectively arranged at both upper ends of the control disk 302, and the L-shaped limit blocks 305 are fixedly connected to the control disk 302. Control blocks 303 are fixedly connected to both lower ends of the control disk 302 respectively. Return springs 304 are fixedly connected to the symmetric sides of the centers of the two groups of control blocks 303 respectively. The other end of the return spring 304 is fixedly connected to a pressing block 202.

[0027] In the above - mentioned method, the control lever 301 in the control device 3 is rotated, so that the control lever 301 rotates, and the control disk 302 at the other end of the control lever 301 rotates. Since the control disk 302 rotates, the two groups of L - shaped limit blocks 305 above the turntable rotate, moving them away from the rectangular groove 204. At the same time, as the control disk 302 rotates, the two groups of control blocks 303 below the control disk 302 rotate, thereby stretching the return spring 304. When disassembling and assembling the drone propeller blade 6 at this time, only the rotating block 4 and the positioning block 401 need to be removed from or installed into the groove and the rectangular groove 204 opened in the fixed block 2. Release the control lever 301, and under the action of the return spring 304, the control device 3 can return to the initial state, so that the connecting block 5 and the propeller blade 6 can be quickly disassembled.

[0028] As Figure 2 and Figure 4 shown, the two sides of the lower end of the rotating block 4 are respectively fixedly connected with positioning blocks 401. The two groups of L - shaped limit blocks 305 are designed with central symmetry, and the positioning blocks 401 match the L - shaped limit blocks 305.

[0029] In the above - mentioned method, the control lever 301 in the control device 3 is rotated, so that the control lever 301 rotates, and the control disk 302 at the other end of the control lever 301 rotates. Since the control disk 302 rotates, the two groups of L - shaped limit blocks 305 above the turntable rotate, moving them away from the rectangular groove 204. When installing the drone propeller blade 6, only the positioning blocks 401 on both sides of the rotating block 4 need to be installed into the rectangular groove 204, so that the L - shaped limit blocks 305 can fix the positioning blocks 401, and thus the drone propeller blade 6 can be quickly installed.

[0030] As Figures 3 to 5 shown, an annular rail groove 201 is opened inside the lower end of the fixed block 2. The two groups of extrusion blocks 202 are respectively arranged in the annular rail groove 201, and the two groups of extrusion blocks 202 are respectively fixedly connected with the fixed block 2. The lower end of the annular rail groove 201 matches the control disk 302, the upper end of the annular rail groove 201 matches the rotation trajectory of the L - shaped limit block 305, and a track through - hole 203 is opened on one side of the annular rail groove 201, and the track through - hole 203 matches the control lever 301.

[0031] In the above method, when preparing to disassemble the drone propeller blade 6, rotate the control lever 301 in the control device 3, so that the control lever 301 rotates within the track through hole 203, and the control disk 302 at the other end of the control lever 301 rotates at the lower end of the annular track groove 201. Due to the rotation of the control disk 302, the two groups of L-shaped limit blocks 305 above the turntable rotate at the upper end of the annular track groove 201 and move away from above the positioning block 401. At the same time, as the control disk 302 rotates, the two groups of control blocks 303 below the control disk 302 rotate, thereby stretching the return spring 304. At this time, lift the rotating block 4 out of the groove opened in the fixed block 2 upward, so that the positioning blocks 401 at both ends below the rotating block 4 move upward along the rectangular groove 204. Release the control lever 301, and under the action of the return spring 304, the control device 3 can return to the initial state, and the connecting block 5 and the propeller blade 6 can be quickly disassembled.

[0032] As Figure 5 shown, the upper end of the fixed block 2 is provided with a groove, and rectangular grooves 204 are respectively opened on both sides of the groove opened in the fixed block 2. The rectangular grooves 204 are arranged at the upper end of the annular track groove 201, and the rectangular grooves 204 are matched with the positioning blocks 401.

[0033] In the above method, when disassembling and assembling the drone propeller blade 6, the rotating block 4 can be moved along the groove opened in the fixed block 2, so that the rotating block 4 can be disassembled and assembled. Moreover, since the rectangular groove 204 is matched with the positioning block 401, when the rotating block 4 moves along the groove opened in the fixed block 2, the positioning block 401 can move along the rectangular groove 204, thereby enabling the quick disassembly and assembly of the drone propeller blade 6.

[0034] The working principle of this utility model is as follows: When preparing to disassemble the drone propeller blade 6, rotate the control lever 301 in the control device 3, so that the control lever 301 rotates within the track through-hole 203, causing the control disk 302 at the other end of the control lever 301 to rotate at the lower end of the annular track groove 201. Due to the rotation of the control disk 302, the two groups of L-shaped limit blocks 305 above the turntable rotate at the upper end of the annular track groove 201 and move away from above the positioning block 401. At the same time, as the control disk 302 rotates, the two groups of control blocks 303 below the control disk 302 rotate, thereby stretching the return spring 304. At this time, move the rotating block 4 upward out of the groove opened in the fixed block 2, so that the positioning blocks 401 at both ends below the rotating block 4 move upward along the rectangular groove 204. Release the control lever 301, and under the action of the return spring 304, the control device 3 can return to the initial state, enabling the quick disassembly of the connecting block 5 and the propeller blade 6; When preparing to install the drone propeller blade 6, just repeat the above process. And when the L-shaped limit block 305 rotates, just install the rotating block 4 in the groove opened in the fixed block 2, and install the positioning block 401 in the rectangular groove 204, then release the control lever 301. Under the elastic function of the return spring 304, the control device 3 can return to the initial state, and the L-shaped limit block 305 can limit and fix the positioning block 401, enabling the fixed installation of the connecting block 5 and the propeller blade 6, thus completing a series of work.

[0035] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
