The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0033] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the mounting component provided in one embodiment of the present invention; Figure 2 yes Figure 1 A partial structural diagram of the mounted components.

[0034] One embodiment of this utility model provides a mounting assembly 100, including a housing 10, a drive member 20, a transmission shaft 30, and mounting arms 40. The housing 10 has a receiving cavity 11. The drive member 20 is mounted on the housing 10, and the transmission shaft 30 is received in the receiving cavity 11. The output end of the drive member 20 is connected to the transmission shaft 30. A guide groove 31 is formed on the circumferential outer surface of the transmission shaft 30. The guide groove 31 is inclined relative to the rotation axis O of the transmission shaft 30. One end of each mounting arm 40 is located inside the housing 10 and received in a corresponding guide groove 31. The drive member 20 can drive the transmission shaft 30 to rotate around the rotation axis of the transmission shaft 30, so that one end of each mounting arm 40 moves up and down along a corresponding guide groove 31, so that the other ends of all the mounting arms 40 move closer to or further away from each other.

[0035] Specifically, the drive unit 20 drives the transmission shaft 30 to rotate around its rotation axis O. When the transmission shaft 30 rotates, the guide groove 31 rotates with it, and the wall of the guide groove 31 abuts against one end of the mounting arm 40, driving that end of the mounting arm 40 to move up and down. When one end of each mounting arm 40 moves upward, the other ends of all the mounting arms 40 move closer together, thus completing the action of grasping the object. When one end of each mounting arm 40 moves downward, the other ends of all the mounting arms 40 move away from each other, thus completing the action of detaching from the object. The entire process only requires the drive unit 20 to control the rotation of the transmission shaft 30, thereby improving the efficiency of the UAV in grasping objects. The drive unit 20 drives the transmission shaft 30 to rotate around its rotation axis O, and the transmission shaft 30 drives one end of multiple mounting arms 40 to move up and down; this reduces the connection structure between the output end of the drive unit 20 and the multiple mounting arms 40, simplifying the overall structure of the mounting assembly 100.

[0036] See Figure 2 , Figure 3 and Figure 4 , Figure 3 yes Figure 1 A cross-sectional view of the first state of the mounted components; Figure 4 yes Figure 1 A cross-sectional structural diagram of the second state of the mounted component.

[0037] In one embodiment, the mounting arm 40 includes a mounting portion 41, a connecting portion 42, and a mounting portion 43. The connecting portion 42 is connected between the mounting portion 41 and the mounting portion 43. One end of the mounting portion 41 facing away from the mounting portion 43 is received in the guide groove 31. The housing 10 has a communication port 12, which communicates with the receiving cavity 11. The connecting portion 42 of each mounting arm 40 passes through a corresponding communication port 12, and the connecting portion 42 is rotatably mounted on the housing 10.

[0038] Specifically, the connecting part 42 is rotatably mounted on the housing 10, and the connecting part 42 acts as a fulcrum, allowing the mounting part 41, the connecting part 42, and the hanging part 43 to rotate relative to the housing 10. The mounting part 41 rotates upward relative to the housing 10, and the corresponding hanging part 43 rotates downward relative to the housing 10 to clamp the item at an angle; when the mounting part 41 rotates downward relative to the housing 10, the corresponding hanging part 43 rotates upward relative to the housing 10 to disengage the item at an angle; thus ensuring the rotation path of the hanging arm 40. The mounting part 41 is installed inside the housing 10 to protect the connection between the mounting part 41 and the drive shaft 30.

[0039] In this embodiment, the end of the mounting part 43 that is away from the connecting part 42 is tilted upward to form a hook structure.

[0040] In one embodiment, the mounting portion 43 includes an extension 431 and a mounting portion 432. The extension 431 is connected between the mounting portion 432 and the connecting portion 42. The extension 431 extends downward from the connecting portion 42 and is inclined relative to the horizontal plane. The extension 431 and the mounting portion 432 have a first preset angle 433. The opening of the first preset angle 433 faces the rotation axis O of the drive shaft 30.

[0041] Specifically, the extension section 431 serves two purposes: firstly, it increases the lever arm, and secondly, it acts as a bend, making the mounting arm 40 resemble a hook. The purpose of this design is that when multiple mounting arms 40 rotate simultaneously, the corresponding mounting sections 432 move closer and further apart, resulting in a better clamping effect.

[0042] In one embodiment, the connecting portion 42 includes a mounting section 421 and a transition section 422. The transition section 422 is connected between the mounting section 421 and the extension section 431. The mounting section 421 and the transition section 422 have a second preset angle 423. The opening direction of the second preset angle 423 is opposite to the opening direction of the first preset angle 433. The mounting section 421 is rotatably connected to the cavity wall of the receiving cavity 11.

[0043] Specifically, the opening orientation of the second preset angle 423 is opposite to that of the opening orientation of the first preset angle 433. A recess will be generated between the end of the mounting section 421 away from the transition section 422 and the end of the transition section 422 away from the mounting section 421. When the connecting part 42 rotates, the recess can play a role in avoiding collision between the connecting part 42 and the side wall of the connecting port 12.

[0044] In this embodiment, the mounting section 421 has a chamfer on the side near the cavity wall of the receiving cavity 11, and the outer surface of the chamfer is arc-shaped, so that the connecting part 42 avoids collision between the connecting part 42 and the cavity wall of the receiving cavity 11 during rotation.

[0045] In one embodiment, the connecting portion 42 includes an arcuate surface 424, which is located on the side of the connecting portion 42 away from the opening of the second preset angle 423, so that there is a gap between the arcuate surface 424 and the sidewall of the communication port 12 when the connecting portion 42 rotates.

[0046] Specifically, the arc-shaped surface 424 is located at the bottom of the connecting part 42, and the center of curvature of the arc-shaped surface 424 is located on the side of the connecting part 42 away from the rotation axis O of the drive shaft 30. The purpose of this arrangement is that during the rotation of the connecting part 42, the arc-shaped surface 424 and the lower side wall of the communication port 12 are always kept at a distance, preventing the connecting part 42 from colliding with the housing 10.

[0047] Furthermore, the curved surface 424 can increase the width of the connecting part 42, thereby increasing the strength of the connecting part 42 and improving the service life of the mounting arm 40.

[0048] In one embodiment, the mounting assembly 100 further includes a retaining block 50, which is housed in a receiving cavity 11. The retaining block 50 is connected to the cavity wall of the receiving cavity 11 and is located above the mounting arm 40. When the mounting arm 40 is used to mount an item, the retaining block 50 abuts against the upwardly moving mounting arm 40.

[0049] Specifically, the drive member 20 drives the transmission shaft 30 to rotate, the mounting part 41 rotates upward relative to the housing 10, and the hanging part 43 rotates downward relative to the housing 10 to clamp the item; the mounting part 41 rotates upward and is located at the end of the guide groove 31, the end face of the mounting part 41 away from the drive member 20 abuts against the clamping block 50, the clamping block 50 abuts against the mounting part 41 so that the mounting part 41 cannot move upward continuously, so as to maintain the state of the hanging arm 40 clamping the item.

[0050] In this embodiment, the clamping block 50 and the housing 10 are integrated to reduce the number of connecting structures, making the overall mounting assembly 100 simpler and reducing production costs.

[0051] In one embodiment, the mounting assembly 100 further includes a mounting plate 60, which is connected to the output shaft of the drive member 20. The mounting plate 60 has a cross-shaped structure and abuts against and is connected to the end face of the drive shaft 30 near the drive member 20.

[0052] Specifically, the output shaft of the drive component 20 passes through the mounting plate 60. When the output shaft of the drive component 20 rotates, it drives the mounting plate 60 to rotate. The mounting plate 60 and the transmission shaft 30 can be connected by screws, and the transmission shaft 30 rotates in turn, so as to ensure that the transmission shaft 30 rotates when the drive component 20 moves, and to prevent slippage between the drive component 20 and the transmission shaft 30.

[0053] See Figure 2 , Figure 3 and Figure 5 , Figure 5 yes Figure 1 A schematic diagram of the structure at the bottom of the housing of the mounting component.

[0054] In one embodiment, the mounting assembly 100 further includes a mounting ear 70, a mounting post 72, and a screw (not shown). The drive unit 20 is connected to the mounting ear 70. The mounting ear 70 has a mounting hole. The mounting post 72 is connected to the housing 10. The screw passes through the mounting hole and is fixedly mounted on the mounting post 72, thereby fixing the mounting ear 70 to the mounting post 72.

[0055] Specifically, the housing of the drive component 20 and the mounting ear 70 can be integrally formed, and the mounting post 72 and the housing 10 can be integrally formed. The mounting post 72 has a threaded hole, and the screw passes through the mounting hole of the mounting ear 70 and is threaded into the threaded hole of the mounting post 72. The nut of the screw presses the mounting ear 70 against the mounting post 72, which can quickly fix the mounting ear 70 to the mounting post 72.

[0056] Furthermore, there are two mounting ears 70, which are located on opposite sides of the drive member 20. Each mounting ear 70 has two mounting holes, and the mounting posts 72 have four corresponding holes.

[0057] In this embodiment, the housing 10 includes an upper housing 14 and a lower housing 15, which are detachably connected to facilitate the maintenance of the mounting assembly 100. The mounting hole is located on the side of the lower housing 15 opposite to the upper housing 14.

[0058] See Figure 6 and Figure 7 , Figure 6 yes Figure 1 Assembly diagram of the drive unit, drive shaft, and mounting arm of the mid-mounted component. Figure 7 yes Figure 1 Another assembly diagram of the drive unit, drive shaft, and mounting arm of the mounting assembly.

[0059] In one embodiment, the drive shaft 30 is a cylindrical structure, and a plurality of guide grooves 31 are formed on the circumferential outer surface of the drive shaft 30. All guide grooves 31 are spirally arranged around the rotation axis O of the drive shaft 30 in the same rotation direction, and the helix angle θ of each guide groove 31 is 25 degrees to 50 degrees.

[0060] Specifically, when the drive shaft 30 rotates, the two ends of the guide groove 31 spiral upwards or downwards accordingly. The mounting portion 41 of the corresponding mounting arm 40, located at the end of the guide groove 31, moves vertically upwards or downwards. The end of the corresponding mounting portion 43, away from the connecting portion 42, rotates downwards or upwards relative to the housing 10. In other words, the mounting portion 41 of the mounting arm 40 does not move horizontally, and the mounting portion 43 does not move horizontally either. This design eliminates the need to consider the horizontal movement of the connecting portion 42, simplifying the rotatable connection between the connecting portion 42 and the housing 10.

[0061] The helix angle θ of each guide groove 31 is between 25 and 50 degrees, meaning that the angle between each guide groove 31 and the plane P perpendicular to the rotation axis O of the drive shaft 30 is between 25 and 50 degrees. This arrangement ensures that when one end of each mounting arm 40 located within the guide groove 31 moves to the opposite end of the guide groove 31, that end of each mounting arm 40 located within the guide groove 31 self-locks with the groove wall. In other words, only when the drive member 20 drives the drive shaft 30 to rotate around the rotation axis O of the drive shaft 30 can one end of each mounting arm 40 located within the guide groove 31 move up and down along the corresponding guide groove 31. When the weight of the item or an external force acts on the mounting arm 40, the end of each mounting arm 40 located within the guide groove 31 will not move up and down along the corresponding guide groove 31, thus allowing the mounting arm 40 to stably mount the item.

[0062] In this embodiment, there are two guide grooves 31, which are located on opposite sides of the drive shaft 30. The two guide grooves 31 are spirally arranged around the rotation axis O of the drive shaft 30 in the same rotation direction.

[0063] There are two mounting arms 40, which are located on opposite sides of the drive shaft 30.

[0064] The shell 10 is roughly cubic in shape. There are two connecting ports 12, which are respectively opened on two opposite side surfaces of the shell 10.

[0065] It is understood that in some other embodiments, the number of guide slots 31, the number of mounting arms 40 and the number of communication ports 12 can be multiple, for example, 3 or 4, and the housing 10 as a whole can be cylindrical or prismatic.

[0066] This utility model also provides an unmanned aerial vehicle, including the mounting component 100 described in any of the above embodiments.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
