DETAILED DESCRIPTION

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0038] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0039] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0041] Drones can be widely used in fields such as seeding, filming, and transportation. When a drone is used in the transportation field, it is usually necessary to configure a lifting mechanism for the drone so that the hook of the lifting mechanism can be used to lift objects for transportation.

[0042] However, when the drone is flying by hooking and lifting objects, electromagnetic interference may occur between the actuator and controller of the lifting mechanism, resulting in technical problems such as the lifting mechanism losing control.

[0043] Please refer to Figures 1-6 This embodiment provides a drone comprising a body and a lifting mechanism 1000. The lifting mechanism 1000 is mounted on the body and can follow the drone's flight to perform transport operations. This embodiment effectively alleviates the aforementioned technical issues by electromagnetically isolating the interior of the lifting mechanism 100, thereby preventing electromagnetic interference and ensuring the operational stability of the lifting mechanism 100.

[0044] In this embodiment, the carrier is a drone, specifically an agricultural drone, which is generally equipped with a lifting device, a spraying device, a seeding device, etc. required for agriculture, and can realize the transportation of goods, spraying irrigation, seeding, etc. Of course, the carrier can also carry a camera, game equipment, etc.

[0045] Among them, the structure of the main body is similar to that of the related technology. For example, the main body of the drone includes a fuselage, a battery, an arm, a motor and a propeller. The battery is assembled on the fuselage, one end of the arm is connected to the fuselage, and the other end of the arm is connected to the motor. The output shaft of the motor is connected to the propeller transmission, and the motor is electrically connected to the battery; the battery passes electric energy to the motor, so that the motor can drive the propeller to rotate, so as to use the rotating propeller to provide lift and realize the flight of the drone body.

[0046] Specifically, the lifting device 1000 includes a landing gear 200 and a lifting mechanism 100. The lifting mechanism 100 is connected to the landing gear 200 via a lifting rope 60. The landing gear 200 is mounted on the bottom of the fuselage. The lifting mechanism 100 is used to lift objects. The lifting mechanism 100 is mounted on the fuselage via the landing gear 200, thereby ensuring easy operation of the lifting mechanism 100 when lifting and unloading objects.

[0047] Specifically, the landing gear 200 is detachably connected to the fuselage, using methods including, but not limited to, snap-fit ​​connections and fasteners such as bolts. This arrangement allows the landing gear 200 and the lifting mechanism 100 to be removed from the fuselage as needed, increasing the flexibility of the drone's operation and allowing for separate maintenance of the landing gear 200 and the lifting mechanism 100 as needed, reducing maintenance costs and difficulty.

[0048] In this embodiment, the landing gear 200 includes a top frame 220, a horizontally arranged crossbar 210, and a plurality of support legs 230. One end of each of the support legs 230 is connected to the top frame 220, and the plurality of support legs 230 are spaced apart around the circumference of the top frame 220. The other ends of the plurality of support legs 230 are used to support the ground or other supporting positions. The crossbar 210 is connected to the top frame 220, and the lifting mechanism 100 is generally distributed in the middle of the crossbar 210. Specifically, the two ends of the crossbar 210 are connected to opposite sides of the top frame 220 via connectors. This arrangement allows the lifting mechanism 100 to be centrally positioned via the crossbar 210, thereby ensuring the balance of the drone lifting objects.

[0049] More preferably, one end of the lifting rope 60 is connected to the cross bar 210 , and the other end is connected to the lifting mechanism 100 .

[0050] Specifically, an adjustment member is provided on the crossbar 210 and / or the suspension rope 60. The adjustment member is disposed at the connection between the crossbar 210 and the suspension rope 60 and is used to adjust the length of the suspension rope 60. In this embodiment, the adjustment member is provided on both the crossbar 210 and the suspension rope 60. In other embodiments, the adjustment member may be provided only on the crossbar 210 or only on the suspension rope 60, and this is not specifically limited here.

[0051] Please refer to Figures 1-6 The lifting mechanism 100 includes a shell 10, a hook 20, a locking assembly 30 and an electrical assembly 40. The shell 10 has an isolated first accommodating cavity 14 and a second accommodating cavity 15. The hook 20 is arranged in the shell 10. The hook 20 can rotate to an unloading position and a mounting position relative to the shell 10. The locking assembly 30 is arranged in the first accommodating cavity 14. The locking assembly 30 is used to lock or unlock the hook 20 according to an electrical control signal. The electrical assembly 40 is arranged in the second accommodating cavity 15. The electrical assembly 40 and the locking assembly 30 are electrically connected.

[0052] It should be noted that the housing 10 includes a force-bearing body 11, a first housing 12, and a second housing 13. The first housing 12 and the second housing 13 are respectively arranged on both sides of the force-bearing body 11 and connected to the force-bearing body 11. A first accommodating cavity 14 is formed between the first housing 12 and the force-bearing body 11, and a second accommodating cavity 15 is formed between the second housing 13 and the force-bearing body 11. The first housing 12 and the second housing 13 are respectively detachably connected to the two sides of the force-bearing body 11. The connection method between the two includes but is not limited to snap-on connection and connection with fasteners such as bolts. The hook 20 is rotatably arranged at the bottom of the force-bearing body 11.

[0053] The locking assembly 30 and the electrical assembly 40 are respectively disposed in the first accommodating cavity 14 and the second accommodating cavity 15 , and can achieve electromagnetic isolation through the force-bearing body 11 .

[0054] To ensure the stability of items suspended on the hook 20, the lifting mechanism 100 further includes a baffle 80, which is rotatably connected to the housing 10 and is used to prevent items suspended on the hook 20 from falling off the hook 20. The baffle 80 is rotatable relative to the housing 10 between a closed position and an open position. When the baffle 80 is in the closed position, it blocks the opening 202 of the hook 20, preventing items suspended on the hook 20 from falling off the hook 20. When the baffle 80 is in the open position, the baffle 80 opens the opening 202 of the hook 20, facilitating loading and unloading of items from the hook 20. This arrangement not only ensures that the baffle 80 prevents items from falling off the hook 20, thereby improving the stability of the hook 20 lifting items, but also prevents the baffle 80 from interfering with the loading and unloading of items on the hook 20.

[0055] Specifically, the bottom of the force-bearing body 11 is provided with a hook shaft hole 110 and a baffle shaft hole 120. The lifting mechanism 100 also includes a baffle shaft 101 and a hook shaft 102. The baffle shaft 101 passes through both the through hole 131 in the baffle 80 and the baffle shaft hole 120, thereby rotatably connecting the baffle 80 and the force-bearing body 11. The hook shaft 102 passes through both the through hole 131 in the hook 20 and the hook shaft hole 110, thereby rotatably connecting the hook 20 and the force-bearing body 11.

[0056] Furthermore, a torsion spring is provided in both the hook shaft hole 110 and the baffle shaft hole 120. The torsion spring in the baffle shaft hole 120 is in a normally closed setting, and the restoring force of the torsion spring can close the baffle 80; the torsion spring in the hook shaft hole 110 is in a normally open setting, and the restoring force of the torsion spring can open the hook 20.

[0057] It should also be noted that the locking assembly 30 includes a driving member 31, a transmission connecting rod 32, and a latch 33. The two ends of the transmission connecting rod 32 are respectively connected to the driving member 31 and the latch 33. The latch 33 is used to lock or unlock the hook 20. The driving member 31 drives the latch 33 to move through the transmission connecting rod 32, thereby locking or unlocking the hook 20.

[0058] In this embodiment, the driving member 31 is a steering gear. The axial extension direction of the steering gear's output shaft forms an angle with the direction of movement of the latch 33, including but not limited to 90°, 88°, 93°, etc. The steering gear's output shaft is in driving connection with the connecting end of the transmission link 32, thereby driving the free end of the transmission link 32 to rotate about its connecting end. This rotation of the transmission link 32 drives the latch 33 connected to the free end of the transmission link 32 to move along its longitudinal extension direction, thereby withdrawing the latch 33 from the rotation path of the hook 20. In other embodiments, the driving member 31 may also be a motor, which is not specifically limited here.

[0059] Specifically, a guide hole is provided on the force-bearing body 11 , and the latch 33 is slidably inserted into the guide hole. The guide hole can limit the moving direction of the latch 33 , thereby improving the problem that the latch 33 is easily displaced.

[0060] In this embodiment, the latch 33 is always set on the path that blocks the rotation of the hook 20. When the item needs to be unloaded, the driving member 31 drives the latch 33 to exit the rotation path of the hook 20, so that the hook 20 can rotate to the unloading position relative to the shell 10.

[0061] Furthermore, a torsion spring is provided on the transmission member, which abuts against the transmission member and the force-bearing body 11 at the same time. The torsion spring is provided so that the transmission member always has the tendency to drive the pin 33 to move to the rotation path that blocks the hook 20, thereby ensuring the stability of the hook 20 in hoisting items.

[0062] In order to further facilitate the unloading of items by the hook 20, a torsion spring is also provided on the hook shaft 102, which is in contact with the hook 20 and the force-bearing body 11 at the same time, so that the hook 20 always has a tendency to rotate toward the unloading position, so that when the driving member 31 drives the pin 33 to exit the rotation path of the hook 20, the hook 20 with the rotation tendency unlocked can automatically rotate to the unloading position under the action of the torsion spring, thereby ensuring the automated unloading and the labor-saving and easy operation of unloading, that is, when unloading is required, only the locking component 30 needs to be electrically controlled, and there is no need to control the hook 20, which has low energy consumption.

[0063] Furthermore, the hook 20 has a bending force point 201 for hanging items and an opening 202 for loading and unloading items. The hook 20 can swing around the first axis 103 on both sides of the second axis 104, and the first axis 103 is perpendicular to the second axis 104. The bending force point 201 and the opening 202 are distributed on both sides of the second axis 104. In this way, the force point for hanging items on the hook 20 is distributed on one side of the axis of the baffle shaft 101, and the opening 202 of the hook 20 is distributed on the other side of the axis of the baffle shaft 101. When an item is hung on the hook 20, the weight of the item causes the hook 20 to tend to rotate toward the hanging position, thus forming a certain self-locking effect and improving the stability of the hook 20 in hanging items. Furthermore, since the hook 20 tends to rotate toward the loading position when hanging items, the latch 33 blocking the path of the hook 20 turning toward the unloading position does not bear the weight of the items. The locking assembly 30 only serves as a secondary insurance to prevent the items from falling off, thereby increasing the service life of the latch 33.

[0064] It should also be noted that the lifting mechanism 100 also includes a counterweight 50, which is disposed in the first accommodating cavity 14 and / or the second accommodating cavity 15 to balance the weight on both sides of the load-bearing body 11. In this embodiment, the counterweight 50 is disposed in both the first accommodating cavity 14 and the second accommodating cavity 15. In other embodiments, the counterweight 50 may be disposed only in the first accommodating cavity 14 or only in the second accommodating cavity 15, without specific limitation herein.

[0065] In this embodiment, the counterweight 50 includes a mounting seat 51 , which is disposed on a side of the force-bearing body 11 close to the first shell 12 . The locking assembly 30 includes a driving member 31 , which is disposed on the mounting seat 51 .

[0066] In addition, the electrical assembly 40 includes a wireless communication module, a circuit board 41, and an antenna. The wireless communication module is mounted on the circuit board 41 for wireless communication with the drone, and the antenna is electrically connected to the wireless communication module. The circuit board 41 is electrically connected to the driver 31, thereby controlling the operation of the driver 31. The antenna communicates with the wireless communication module of the electrical assembly 40, specifically, the Bluetooth module on the circuit board 41.

[0067] In this embodiment, the electrical component 40 further includes a battery module 42 . The battery module 42 is electrically connected to the driving component 31 . The battery module 42 is used to supply power to the driving component 31 .

[0068] The electrical component 40 and the locking component 30 are respectively arranged in the first accommodating cavity 14 and the second accommodating cavity 15. Electromagnetic isolation can be achieved through the force-bearing body 11 to prevent the coil inside the servo from causing electromagnetic interference to the wireless communication in the electrical component 40, thereby preventing loss of control. This ensures the safety and accuracy of the hook 20 in lifting items, and at the same time ensures the accurate control of the lifting mechanism 100 by the drone.

[0069] In this embodiment, the circuit board 41 is provided with at least one of a charging port 411, an indicator light 412, and a button 413. The second shell 13 is penetrated by at least one through hole 131, and the through hole 131 is used to expose at least one of the charging port 411, the indicator light 412, and the button 413. Specifically, the circuit board 41 is provided with a charging port 411, an indicator light 412, and a button 413. The second shell 13 is penetrated by three through holes 131, which are used to expose the charging port 411, the indicator light 412, and the button 413, respectively. The operator and the drone pilot can remotely communicate whether the mounting is completed or not through the button 413 and the indicator light 412 on the second shell 13, further ensuring the safety of the drone and the cargo taking off and landing. In other embodiments, the second shell 13 may have only one through hole 131 or another number of through holes 131, which are not specifically limited here.

[0070] It should also be noted that the lifting mechanism 100 also includes a lifting rope 60 and an adjusting assembly 70 . The adjusting assembly 70 is connected to the top of the shell 10 , and the lifting rope 60 is connected to the adjusting assembly 70 . The adjusting assembly 70 is used to adjust the length of the lifting rope 60 .

[0071] Specifically, the adjustment assembly 70 includes a cam 71. A mounting portion 130 is provided at the top of the force-bearing body 11. A mounting space is defined between the mounting portion 130 and the top of the force-bearing body 11. The cam 71 is rotatably disposed within the mounting space, and a gap is defined between the cam 71 and the mounting space to accommodate the sling 60. A sling hole 1301 is formed through the mounting portion 130. One end of the sling hole 1301 communicates with the top surface of the mounting portion 130, and the other end communicates with the side surface of the mounting portion 130. One end of the sling 60 enters the sling hole 1301 via the top surface of the mounting portion 130, passes through the sling hole 1301 from the side surface of the mounting portion 130, and then enters the mounting space. The rope section of the sling 60 located within the mounting space contacts the cam 71.

[0072] Furthermore, a gear is provided on the side of the cam 71 close to the rope 60, thereby increasing the friction between the surface of the cam 71 and the rope 60 and improving the locking reliability. A torsion spring is provided at the rotating shaft position of the cam 71, which provides a force that always presses the cam 71 toward the rope 60. When the rope 60 moves along the Figure 2When the cam 71 moves in the direction of A in the figure, the friction force can be used to drive the cam 71 to rotate in the direction of loosening the rope 60, so that the length of the rope 60 can be adjusted. Figure 2 When the lever moves in the direction B, the friction force can be used to drive the cam 71 to rotate in the direction of pressing the hanging rope 60, thereby locking the hanging rope 60 and making it impossible to adjust the hanging rope 60.

[0073] In other embodiments, the contact area between the cam 71 and the sling 60 can be increased to increase friction therebetween, thereby improving locking reliability. Alternatively, grooves can be provided on the surface of the cam 71 to increase friction therebetween, thereby improving locking reliability. This is not specifically limited herein.
