DETAILED DESCRIPTION

[0043] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0044] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization given by the corresponding device owner.

[0045] In the present disclosure, the orientation words such as "up, down" generally refer to the up and down in space when the suspension device is in use, unless otherwise stated. "Inside, outside" refers to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another element, and do not have sequentiality and importance. In addition, in the description with reference to the drawings, the same reference signs in different drawings represent the same elements.

[0046] According to a first aspect of the present disclosure, a suspension assembly is provided, as shown in FIGS. 1-12, which includes a base body 1 and a hoisting assembly 2, the hoisting assembly 2 including two carriers 210 connected to the base body 1, the two carriers 210 being configured to move towards or away from each other to switch between a carrying position and a release position; in the carrying position, the two carriers 210 can cross each other to form an open upward limiting groove 3, and wherein the carrier 210 extends from one side of the limiting groove 3 to the opposite side to form at least part of the bottom wall 320 of the limiting groove 3 and the side wall 330 on the other side, the limiting groove 3 being used to carry the transfer part 410 of the goods 4, and the side wall 330 being used to limit the transfer part 410 of the goods 4, and the opening 310 of the limiting groove 3 being used for the transfer part 410 to enter or exit the limiting groove 3.

[0047] By the above technical solution, i.e., the suspension assembly provided by the present disclosure, the two carriers 210 are configured to move towards or away from each other, so that the two carriers 210 can switch between the carrying position and the release position. When the suspension assembly is applied to, for example, a drone, the drone can perform goods delivery work through the suspension assembly. Since when the two carriers 210 are in the carrying position, the two carriers 210 can cross each other to form the limiting groove 3 with the opening 310 upward and used to carry the transfer part 410 of the goods 4, and the side wall 330 of the limiting groove 3 can be used to limit the transfer part 410 of the goods 4, when the transfer part 410 of the goods 4 is placed in the limiting groove 3, the transfer part 410 of the goods 4 can be used to limit the two carriers 210 in the carrying position, so as to achieve the purpose of automatically locking the two carriers 210 in the carrying position through the cooperation of the limiting groove 3 of the carrier 210 and the transfer part 410 of the goods 4, effectively reducing the possibility of the goods 4 falling due to the disconnection of the two carriers 210 (switching from the carrying position to the release position) during the transportation of the goods 4, and improving the reliability, which helps to improve the quality and safety of goods delivery.

[0048] In addition, since the opening 310 of the limiting groove 3 is upward (for example, along the up-down direction of the drawing plane of FIG. 3, or can also refer to the vertical direction), in the process of the transfer part 410 of the goods 4 exiting through the limiting groove 3, the gravity of the suspension assembly can be used to overcome the friction between the limiting groove 3 and the transfer part 410, which helps the transfer part 410 to exit through the opening 310 of the limiting groove 3, and the side wall 330 of the limiting groove 3 and the transfer part 410 of the goods limit each other, which can also improve the stability of the goods 4 during the exiting process. After the transfer part 410 exits the limiting groove 3, since the limiting between the two bearing pieces 210 is released, the two bearing pieces 210 can move away from each other, so that the two bearing pieces 210 quickly switch to the release position, facilitating the disengagement operation of the two bearing pieces 210.

[0049] It should be noted that in the related art, in order to reduce the risk of goods falling during the goods delivery process, an unmanned aerial vehicle usually separately configures an electrically controlled locking mechanism at the hook for hoisting the goods, so as to realize the locking and unlocking of the hook through the locking mechanism, thereby reducing the risk of goods falling during the goods transportation process. However, the above arrangement for realizing the self-locking of the hook makes the overall structure of the unmanned aerial vehicle more complex, which is not conducive to the lightweight design of the unmanned aerial vehicle. In addition, the electric control also has the risk of electrical failure, which has certain safety hazards. In the present disclosure, the side wall 330 of the limiting groove 3 formed by the two bearing pieces 210 crossing each other in the bearing position is used to limit the transfer part 410 of the goods 4, so as to achieve the purpose of automatically locking the two bearing pieces 210 in the bearing position. This effectively reduces the possibility of the goods 4 falling due to the disengagement (switching from the bearing position to the release position) of the two bearing pieces 210 during the transportation of the goods 4. Compared with the electrically controlled locking structure in the related art, the suspension assembly provided by the present disclosure can automatically lock (that is, automatically lock the two bearing pieces 210 in the bearing position) the two bearing pieces 210 without the need to additionally add an electrically controlled locking mechanism. The overall structure is simpler and is conducive to the lightweight design of the unmanned aerial vehicle.

[0050] In addition, since the goods 4 itself has a certain gravity, in the process of the unmanned aerial vehicle delivering the goods 4, the gravity of the goods 4 can be used to make the transfer part 410 of the goods 4 more stably placed in the limiting groove 3, which has high reliability. In addition, the structure arrangement of the two bearing pieces 210 provided by the present disclosure can quickly disengage the two bearing pieces 210 crossing each other and move away from each other to the release position after the transfer part 410 exits the limiting groove 3, which helps to improve the disengagement success rate of the two bearing pieces 210 after the transfer part 410 of the goods 4 exits the limiting groove 3.

[0051] In some embodiments, as shown in FIGS. 7-10, the carrier 210 can include carrier arms 211, which include carrier segments 2111 and stop segments 2112 arranged in an L shape, in the carrying position, at least part of the carrier segments 2111 form the bottom wall 320 of the limiting groove 3, and the stop segments 2112 form the side wall 330 of the limiting groove 3, so that when the carrier 210 is in the carrying position, the two carrier arms 211 can form the upward limiting groove 3 when they intersect each other, which is simple in structure and easy to manufacture and install.

[0052] For example, as shown in FIGS. 7-10, an avoiding groove 2113 can be formed in one of the two carrier arms 211 inside the corresponding carrier segment 2111 and stop segment 2112, so that when the carrier 210 is in the carrying position and the two carrier arms 211 intersect each other, the corresponding carrier segment 2111 and stop segment 2112 of the other carrier arm 211 can be placed in the avoiding groove 2113, thereby forming the upward limiting groove 3 between the two carrier arms 211, so that when the transfer part 410 of the goods 4 is placed in the limiting groove 3, the two carriers 210 can be limited in the carrying position by the transfer part 410 of the goods 4, so as to achieve the purpose of automatically locking the two carriers 210 in the carrying position by the cooperation between the limiting groove 3 of the carrier 210 and the transfer part 410 of the goods 4, and improve the reliability of the goods 4 during transportation, which helps to improve the quality and safety of goods delivery.

[0053] The specific embodiment that one of the two carrier arms 211 has an avoiding groove 2113 formed inside the corresponding carrier segment 2111 and stop segment 2112 is exemplary, in other embodiments not shown, the carrier segments and stop segments of the two carrier arms can also be constructed as the same shape structure, and an avoiding gap can be formed at the end of the corresponding carrier segment and stop segment, so that when the carrier is in the carrying position and the two carrier arms intersect each other, the two carrier arms can be placed in the corresponding avoiding gap, and the upward limiting groove 3 can also be formed between the two carrier arms 211, and the disclosure is not limited thereto, and the purpose is to form the upward limiting groove 3 between the two carriers 210 when the carrier 210 is in the carrying position and the two carrier arms 211 intersect each other.

[0054] In some embodiments, as shown in FIGS. 4-10, the carrier 210 can further include a movable arm 212 movably connected to the base 1, and the carrier arm 211 is arranged on the movable arm 212, so that when the delivery personnel manually pushes or drives the two carriers 210 to move closer to or away from each other by the driving device (to be described in detail below) 1010, the relative movement between the movable arm 212 and the base 1 is generated, and then the carrier arm 211 on the movable arm 212 is driven to move, so as to achieve the purpose of switching the two carriers 210 between the carrying position and the release position.

[0055] For example, as shown in FIGS. 4-10, the movable arm 212 of the two carriers 210 can be hinged to the base 1, and the suspension assembly can further include an actuating rod 6 and a second elastic reset member 7 movably connected to the base 1, the actuating rod 6 is connected to the two carriers 210, so as to drive the movable arm 212 of the two carriers 210 to rotate on the base 1 to move closer to or away from each other by the relative movement between the actuating rod 6 and the base 1, so as to realize the switching between the two carriers 210 between the carrying position and the release position, and the second elastic reset member 7 is connected to the actuating rod 6 and the base 1, so as to provide the elastic force for the two carriers 210 to move from the carrying position to the release position, so as to facilitate the two carriers 210 to be automatically reset from the carrying position to the release position under the elastic force of the second elastic reset member 7 after the transfer part 410 of the goods 4 exits the limiting groove 3, which is good in controllability, simple in overall structure and high in reliability.

[0056] In addition, due to the arrangement of the second elastic reset member 7, when the delivery personnel does not manually push or drive the two carriers 210 to move closer to each other by the driving device 1010, the two carriers 210 can be in the release position in the natural state, and under the elastic force of the second elastic reset member 7, it is helpful to improve the success rate of the two carriers 210 to be released (switched from the carrying position to the release position), so as to facilitate the transfer part 410 of the goods 4 to enter and exit between the two carriers 210, and facilitate the development of goods delivery work.

[0057] In the embodiments, as shown in FIGS. 4-10, the base 1 is sleeved on the actuating rod 6, and the outer side wall of the rod segment of the actuating rod 6 located in the base 1 can be provided with an outwardly protruding sliding block 610, and the inner wall surface of the base 1 is provided with a sliding groove 120 in sliding cooperation with the sliding block 610, the sliding block 610 moves in the sliding groove 120 and is limited by the protrusions 130 formed on the inner wall surface of the sliding groove 120, so that the sliding connection of the sliding block 610 and the sliding groove 120 can improve the stability of the actuating rod 6 during movement, reduce the shaking, and improve the reliability, the goods delivery quality and safety.

[0058] Exemplarily, as shown in FIGS. 4-10, the second elastic reset member 7 can be a compression spring 710 connected to the actuating rod 6 and the base body 1, for example, the compression spring 710 can be arranged between the top surface of the sliding block 610 and the bottom surface of the sliding groove 120, so that when the two carriers 210 are moved close to each other manually by the delivery personnel or by driving the driving device 1010, the sliding block 610 of the actuating rod 6 can press the compression spring 710, so that the compression spring 710 is in a compressed state, and when the transfer part 410 of the goods 4 is placed in the limiting groove 3, the two carriers 210 are limited in the carrying position, at this time the compression spring 710 is always compressed, and after the transfer part 410 of the goods 4 is taken out of the limiting groove 3, the compression spring 710 recovers from the compressed state to the elongated state, so that the two carriers 210 can be automatically reset from the carrying position to the release position under the elastic force of the compression spring 710, and the overall structure is simple and has high reliability.

[0059] The specific embodiment of the above-mentioned second elastic reset member 7 being a compression spring 710 is exemplary, and in other embodiments, the above-mentioned second elastic reset member 7 can also be, for example, a rubber spring or a composite spring, and the like, and the purpose is to be able to provide the elastic force for moving the two carriers 210 from the carrying position to the release position, and those skilled in the art can adaptively design according to the actual application requirements.

[0060] In addition, the movable arms 212 of the two carriers 210 can be hinged to the base body 1, and the relative movement of the actuating rod 6 and the base body 1 drives the movable arms 212 of the two carriers 210 to rotate on the base body 1 to move close to or away from each other, that is, as shown in FIG. 4, the first end of the movable arm 212 is connected to the actuating rod 6, the second end of the movable arm 212 is provided with the carrying arm 211, and the intermediate end between the first end and the second end of the movable arm 212 is hinged to the base body 1, so that the relative movement of the actuating rod 6 and the base body 1 drives the movable arms 212 of the two carriers 210 to rotate on the base body 1 to move close to or away from each other, thereby driving the carrying arms 211 of the two carriers 210 to rotate close to or away from each other, so that the two carrying arms 211 can be crossed by rotating close to or away from each other to form the above-mentioned limiting groove 3.

[0061] The specific embodiment of the above-mentioned two carrying arms 211 rotating close to or away from each other to cross each other to form the limiting groove 3 is exemplary, and in other embodiments not shown, those skilled in the art can adaptively design the specific structure of the movable arm 212, so that the two carrying arms 211 can also cross each other by moving linearly close to or away from each other to form the limiting groove 3, and the specific structure of the movable arm 212 is not specifically limited in the present disclosure, and those skilled in the art can adaptively design according to the requirements by referring to the existing movement mechanism of the mechanical claw, which will not be described in detail herein.

[0062] In order to facilitate the loading of the goods 4 between the two carriers 210 even when the two carriers 210 are in the carrying position, in some embodiments, as shown in FIGS. 5-8, the carrier arm 211 can be rotatably connected to the movable arm 212, and in the carrying position, the two carrier arms 211 are in the crossed position to form the limiting groove 3, and the two carrier arms 211 are configured to rotate away from each other from the crossed position to the separated position under the pushing of the transfer part 410, so that in the separated position, the transfer part 410 can pass through the gap 5 between the two carrier arms 211, so that the goods 4 can be conveniently loaded between the two carriers 210 even when the two carriers 210 are in the carrying position, improving the applicability of the suspension assembly.

[0063] In addition, in order to facilitate the automatic resetting of the two carrier arms 211 to the crossed position after rotating away from each other from the crossed position to the separated position under the pushing of the transfer part 410, so as to place the transfer part 410 of the goods 4 in the limiting groove 3 formed between the two carrier arms 211, as shown in FIGS. 5-8, the carrier 210 can further include a first elastic reset member 213 connected to the carrier arm 211 and the movable arm 212, for providing elastic force of the carrier arm 211 from the separated position to the crossed position, so as to facilitate the automatic resetting of the two carrier arms 211, good controllability and high reliability.

[0064] For example, as shown in FIGS. 5-8, the first elastic reset member 213 can be configured as a torsion spring 2131, the carrier arm 211 is rotatably arranged in the mounting groove 2122 of the movable arm 212 through the rotating shaft 21, the torsion spring 2131 is sleeved on the rotating shaft 21 and one end abuts against the bottom wall surface 2123 of the mounting groove 2122, and the other end abuts against the carrier arm 211, in the crossed position, the torsion spring 2131 provides elastic force of the carrier arm 211 abutting against the bottom wall surface 2123 of the mounting groove 2122, to form the limiting groove 3 described above, in the separated position, the transfer part 410 pushes the carrier arm 211 to overcome the elastic force and can rotate from the side away from the bottom wall surface 2123 of the mounting groove 2122 towards the inner side of the movable arm 212, to form the gap 5 between the two carrier arms 211 for the transfer part 410 to pass through.

[0065] It should be noted that, for example, when the cargo delivery operation needs to be performed by the unmanned aerial vehicle, the transfer part 410 of the cargo 4 can be manually delivered to the lower side of the two bearing members 210 by the delivery personnel or by a mechanical arm, etc. When the two bearing members 210 are located at the release position, for example, the transfer part 410 of the cargo 4 can be directly delivered to the space between the two bearing members 210. After the transfer part 410 is delivered to the space between the two bearing members 210, the two bearing members 210 are moved towards each other by the delivery personnel manually or by the driving device 1010, so that the transfer part 410 of the cargo 4 is placed in the limiting groove 3. In this way, the two bearing members 210 are automatically locked in the bearing position by the cooperation between the limiting groove 3 of the bearing member 210 and the transfer part 410 of the cargo 4.

[0066] When the two bearing members 210 are located at the bearing position, for example, the two bearing arms 211 can be moved away from the cross position to the separation position by pushing the two bearing arms 211 against the elastic force of the torsional spring 2131 through the transfer part 410 of the cargo 4. When the transfer part 410 enters the space between the two bearing members 210 and is separated from the two bearing arms 211, the two bearing arms 211 are automatically reset to the cross position under the elastic force of the torsional spring 2131. Then, the transfer part 410 of the cargo 4 is placed in the limiting groove 3. In this way, the two bearing members 210 are automatically locked in the bearing position by the cooperation between the limiting groove 3 of the bearing member 210 and the transfer part 410 of the cargo 4.

[0067] In the present disclosure, the rotation angle of the bearing arm 211 relative to the movable arm 212 is not specifically limited. For example, the bearing arm 211 can be rotated by 90° from one side of the bottom wall surface 2123 of the mounting groove 2122 towards the inner side of the movable arm 212. The purpose is to enable the transfer part 410 of the cargo 4 to pass through the gap 5 between the two bearing arms 211. Those skilled in the art can adaptively design it according to actual application requirements.

[0068] In addition, in some embodiments, referring to FIGS. 4-8, the movable arm 212 can have a first guide surface 2121 for guiding the transfer part 410 to move towards the two bearing arms 211 in the bearing position to push the two bearing arms 211 to switch to the separation position. The first guide surface 2121 can be an inclined surface or an arc surface formed on the movable arm 212, etc. The present disclosure does not make specific limitations thereon, and those skilled in the art can adaptively design it according to actual application requirements.

[0069] In addition, in some embodiments, referring to FIGS. 4-10, the suspension assembly can further include a guide structure 8 connected to the actuating rod 6, which can include a guide rod 810 located between the two carriers 210, and the guide rod 810 is used to pass through the guide hole 411 of the transfer part 410 to guide the movement of the transfer part 410, so that the transfer part 410 can stably enter and exit the limiting groove 3 formed between the two carriers 211 through the opening 310 along the extension direction of the guide rod 810, avoiding the problem of being stuck between the two carriers 210 after the transfer part 410 of the goods 4 exits the limiting groove 3, affecting the disengagement (from the carrying position to the release position) of the two carriers 210, therefore, the setting of the guide rod 810 can help to improve the success rate of disengagement of the two carriers 210 after the transfer part 410 of the goods 4 exits the limiting groove 3, and the limiting cooperation between the guide rod 810 and the guide hole 411 of the transfer part 410 can also reduce the shaking of the goods 4 during movement, thereby improving the quality and safety of goods delivery.

[0070] In addition, in some embodiments, referring to FIGS. 4-10, the guide structure 8 can further include two guide parts 820 arranged oppositely, each having a second guide surface 821, and the two guide parts 820 have a guide gap 822, the two second guide surfaces (which can be inclined surfaces or arc surfaces) 821 are used to guide the guide hole 411 of the transfer part 410 to be sleeved on the guide rod 810 and guide the transfer part 410 to enter the guide gap 822, which can further improve the success rate of disengagement of the two carriers 210 after the transfer part 410 of the goods 4 exits the limiting groove 3, reduce the shaking of the goods 4 during movement, and improve the quality and safety of goods delivery.

[0071] For example, referring to FIGS. 4-10, the actuating rod 6 can be arranged in the base body 1 and one end thereof is connected to the driving device (to be described below) 1010, and the other end is provided with a connecting part 620 connected to the first end of the movable arm 212, so that the relative movement between the actuating rod 6 and the base body 1 driven by the driving device 1010 can drive the movable arms 212 of the two carriers 210 to rotate towards or away from each other on the base body 1, so as to switch the two carriers 210 between the carrying position and the release position, and the guide rod 810 and the guide part 820 can be formed on the bottom of the connecting part 620 to guide the transfer part 410 to enter and exit the limiting groove 3 formed between the two carriers 211.

[0072] The number of guide rods 810 can be one or two, and the two guide parts 820 can be arranged in pairs, and the number of pairs can be more, which is not limited in the present disclosure, and can be designed according to the actual application requirements by those skilled in the art.

[0073] In addition, in some embodiments, as shown in FIGS. 9 and 10, the two guide rods 810 and the two pairs of guide portions 820 form a clearance space 9 to clear the cross arrangement of the two carriers 210, so as to facilitate the switching of the two carriers 210 between the carrying position and the releasing position.

[0074] In addition, the specific connection mode of the actuating rod 6 and the connecting portion 620 is not specifically limited in the present disclosure, for example, it can be integrally formed, or it can also be assembled and connected, for example, it can be connected through fasteners such as bolts, and the like, and the present disclosure does not specifically limit such transformation modes, and a person skilled in the art can adaptively design according to the needs. In addition, the specific arrangement structure of the actuating rod 6, the connecting portion 620 and the base body 1 is not specifically limited in the present disclosure, and the purpose is to be able to drive the connecting portion 620 to move synchronously during the movement of the actuating rod 6, and drive the movable arm 212 to rotate on the base body 1 synchronously through the connecting portion 620, thereby being able to realize the switching of the two carriers 210 between the carrying position and the releasing position.

[0075] According to a second aspect of the present disclosure, a suspension device is provided, which comprises the suspension assembly provided in the first aspect and a suspension body 10, and the suspension body 10 comprises a driving device 1010 for driving the suspension assembly to move relative to the suspension body 10, so that the suspension assembly has a plurality of cargo transfer positions (which can be a cargo pickup position or a cargo unloading position) relative to the suspension body 10. The suspension device can effectively reduce the possibility of falling during cargo transportation, and improve the quality and safety of cargo distribution. In addition, the suspension device also has all the beneficial effects of the above-mentioned suspension assembly, which will not be described herein again. It should be understood that in other embodiments, the suspension device can replace the suspension assembly provided in the first aspect with a suspension assembly in other technologies, and the beneficial effects of improving the quality and safety of cargo distribution can also be obtained.

[0076] In some embodiments, as shown in FIGS. 1 to 11, the suspension body 10 can comprise a box body 1020, the bottom of the box body 1020 is provided with a channel 1021, and the plurality of cargo transfer positions comprises a first cargo transfer position, in which the suspension assembly is at least partially received into the channel 1021. In this way, when the unmanned aerial vehicle is performing cargo distribution operation, for example, since the suspension assembly is received in the channel 1021, the stability during cargo transportation can be improved, which helps to improve the quality and safety of cargo distribution, and when the unmanned aerial vehicle flies to a predetermined position, the suspension assembly can be driven by the driving device 1010 to move from the first cargo transfer position received in the box body 1020 to a second cargo transfer position located outside the box body 1020, for example, to facilitate the operation of picking up or unloading the cargo.

[0077] In addition, in order to facilitate the re-storing of the base body 1 into the channel 1021 and still keep the base body 1 at the preset storing position after the base body 1 extends out of the cabinet 1020, in some embodiments, as shown in FIG. 3 and FIG. 11, one of the inner side wall of the channel 1021 and the outer side wall of the base body 1 is provided with a positioning structure 11, and the other is provided with a positioning matching structure 12. In the first goods handover position, the positioning structure 11 cooperates with the positioning matching structure 12. Exemplarily, the positioning structure 11 can be a positioning groove, and the positioning matching structure 12 can be a positioning protrusion capable of cooperating with the positioning groove. In this way, after the base body 1 is re-stored into the channel 1021, the positioning structure 11 plays a role of positioning and guiding, which can ensure that the base body 1 continues to be at the preset storing position. In addition, the cooperation between the positioning structure 11 and the positioning matching structure 12 can also improve the connection reliability of the base body 1 and the cabinet 1020, reduce the possibility of shaking, and help improve the quality and safety of goods distribution.

[0078] In addition, in some embodiments, as shown in FIG. 3 and FIG. 11, an opening of the channel 1021 can be formed with an extension section 1022 located outside the cabinet 1020 and in a trumpet shape, so that after the base body 1 is re-stored into the channel 1021, the base body 1 can be guided back into the channel 1021 through the trumpet-shaped extension section 1022. In addition, an outer side wall of the base body 1 can be formed with a protrusion 110 extending outward. In the first goods handover position, the protrusion 110 abuts against an inner wall surface of the extension section 1022, thereby limiting and fixing the base body 1, further improving the connection reliability of the suspension assembly and the cabinet 1020, reducing the possibility of shaking, and helping to improve the quality and safety of goods distribution.

[0079] The driving device 1010 can be designed adaptively according to actual application requirements. For example, in some embodiments, referring to FIGS. 3 and 11, the driving device 1010 can include a motor 1011, a winding drum 1012 connected to the motor 1011, and a flexible cable 1013 capable of being wound on the winding drum 1012, one end of the flexible cable 1013 being fixedly connected to the actuating rod 6 of the suspension assembly. The driving device 1010 is configured to wind the flexible cable 1013 by the winding drum 1012 at the first goods transfer position, so as to drive the two carriers 210 to the carrying position by the actuating rod 6, so as to achieve the purpose of driving the two carriers 210 to move close to each other by the driving device 1010, so as to achieve the purpose of stably maintaining the two carriers 210 in the carrying position by the traction force of the driving device 1010, thereby playing a double insurance role. In this way, even if the transfer part 410 of the goods 4 exits the limiting groove 3, the two carriers 210 can still be stably maintained in the carrying position under the action of the traction force of the flexible cable 1013. In addition, winding or releasing the flexible cable 1013 by the driving device 1010 can also achieve switching of the suspension assembly between a plurality of goods transfer positions, such as between the first goods transfer position and the second goods transfer position. The present disclosure is not limited thereto.

[0080] In addition, in some embodiments, referring to FIGS. 3 and 11, at least one guide roller 13 and at least one pressure roller 14 can also be arranged in the box 1020, the flexible cable 1013 passing around the at least one guide roller 13 and through the gap between the oppositely arranged guide roller 13 and pressure roller 14, so as to guide the movement of the flexible cable 1013 by the guide roller 13, and at the same time, the cooperation of the guide roller 13 and the pressure roller 14 can also reduce the shaking of the flexible cable 1013 during movement, thereby improving the reliability of the connection between the flexible cable 1013 and the guide roller 13. The specific arrangement number and specific structure of the above-mentioned guide roller 13 and pressure roller 14 can be designed adaptively according to actual needs. Those skilled in the art can select any known guide roller 13 and pressure roller 14 according to actual conditions, and the present disclosure is not limited thereto.

[0081] In addition, in some embodiments, referring to FIGS. 3 and 11, a fuse device 15 can also be arranged in the box 1020, for selectively fusing the flexible cable 1013, so that the suspension assembly is separated from the box 1020. In this way, when the suspension assembly is entangled or pulled by an obstacle during, for example, the flight of the unmanned aerial vehicle, the fuse device 15 can be controlled by, for example, the control module 22 to fuse the flexible cable 1013, so as to achieve the separation of the suspension assembly from the box 1020, thereby reducing the possibility of the unmanned aerial vehicle falling and ensuring the safety of the unmanned aerial vehicle.

[0082] In addition, in some embodiments, as shown in FIGS. 3 and 11, the box 1020 can further be provided with a locking device 16, which includes a movable locking rod 1610, and the base body 1 and / or the actuating rod 6 is provided with a plug-in portion 17 for the insertion of the locking rod 1610 at the first cargo handover position. For example, the plug-in portion 17 can be a plug hole formed on the sidewall of the base body 1 and the slider 610 of the actuating rod 6. After the base body 1 of the suspension assembly is again accommodated in the predetermined accommodation position in the passage 1021 of the box 1020, the locking rod 1610 can be controlled to pass through the through hole on the sidewall of the passage 1021 and then moved into the plug hole, so as to achieve the limiting and fixing of the suspension assembly, play the role of insurance, reduce the risk of the suspension assembly coming out of the box 1020, further improve the connection reliability of the suspension assembly and the box 1020, reduce the possibility of shaking, and help to improve the quality and safety of cargo distribution.

[0083] In order to facilitate the monitoring of whether the suspension assembly moves to the predetermined accommodation position in the passage 1021 of the box 1020, in some embodiments, as shown in FIGS. 3 and 11, the box 1020 can further be provided with a position sensor 18 for monitoring the position of the suspension assembly, and the position sensor 18 can be signal-connected with the control module 22. After the position sensor 18 monitors that the base body 1 of the suspension assembly is again accommodated in the predetermined accommodation position in the passage 1021 of the box 1020, for example, the position information can be transmitted to the control module 22, so that the control module 22 can control the locking rod 1610 of the locking device 16 to extend and be inserted into the plug hole of the slider 610 of the base body 1 and the actuating rod 6, thereby achieving the limiting and fixing of the suspension assembly.

[0084] It should be noted that the above-mentioned specific embodiments of the driving device 1010 are exemplarily constructed as the motor 1011, the winding drum 1012 and the flexible cable 1013. In other embodiments not shown, the rotation of the motor can also be converted into the linear reciprocating motion of the actuating rod 6 of the suspension assembly through the cooperation of the motor and the gear or cam structure, or the actuating rod 6 can also be driven to move linearly through the cylinder. The present disclosure is not limited thereto, and the purpose is to achieve the linear reciprocating motion of the actuating rod 6 of the suspension assembly through the driving device 1010, and then drive the two bearing members 210 to move towards or away from each other, so as to switch between the bearing position and the release position.

[0085] In addition, the specific structure of the locking device 16, the position sensor 18, the motor 1011, the fuse device 15 and the control module 22 is not limited in the present disclosure, and any known structure can be selected and designed according to the actual situation by those skilled in the art, and the present disclosure will not be described in detail.

[0086] According to a third aspect of the present disclosure, a UAV is provided, which comprises the suspension device provided in the second aspect. The suspension body 10 is connected to the fuselage of the UAV. The UAV can effectively reduce the possibility of falling during the transportation of goods and improve the quality and safety of the delivery of goods during the delivery of goods. In addition, the UAV also has all the beneficial effects of the suspension device, and the present disclosure will not be described here.

[0087] In some embodiments, referring to FIGS. 1-3, the suspension body 10 can be provided with an adapter bracket 19 connected to the fuselage. Correspondingly, the fuselage of the UAV can be provided with a connection structure such as a screw hole or a quick-release clamping slot, so as to realize the stable connection of the suspension device to the fuselage of the UAV through the adapter bracket 19 by means of fasteners such as screws, which is convenient for installation and operation and has high reliability.

[0088] In addition, the specific structure of the adapter bracket 19 is not limited in the present disclosure, and the purpose is to realize the stable connection of the suspension device to the fuselage of the UAV through the adapter bracket 19. Those skilled in the art can design it adaptively according to the actual application requirements. In addition, the adapter bracket 19 and the channel 1021 can be arranged relatively, so as to facilitate the UAV to take or unload the goods 4 through the suspension device after the UAV is moved to the predetermined goods transfer area.

[0089] In addition, in some embodiments, referring to FIG. 1, a three-dimensional force sensor 20 can be arranged between the suspension body 10 and the adapter bracket 19 to monitor the movement state of the UAV and / or weigh the goods 4, that is, it can be understood that the three-dimensional force sensor 20 can collect data of the weight, pressure, tension and other three-dimensional forces of the suspension device and the goods 4 thereon, and transmit the collected data to the control module 22, so that the control module 22 can realize the sway elimination operation of the UAV based on the data information fed back by the three-dimensional force sensor 20, thereby improving the stability and safety of the UAV flight. The specific structure of the three-dimensional force sensor 20 can be designed adaptively according to actual needs, and any known three-dimensional force sensor 20 can be selected by those skilled in the art according to actual conditions, and the present disclosure is not limited in this regard.

[0090] Based on the above embodiments, the present disclosure exemplarily describes the goods delivery process of the UAV, as follows:

[0091] a. UAV picks up goods:

[0092] By controlling the UAV to fly to the preset position, the suspension assembly can be in the first goods handover position. By controlling the UAV to descend, for example, when the two carriers 210 are in the release position, referring to FIG. 4, the delivery personnel can manually or through a mechanical arm or the like to realize the transfer of the transfer part 410 of the goods 4 to the lower side of the two carriers 210, then lift the goods 4 and make the transfer part 410 of the goods 4 guide the transfer part 410 into the guide gap 822 along the second guide surface 821 on the guide part 820 on the actuating rod 6 and make the guide hole 411 of the transfer part 410 sleeve the guide rod 810. In this way, when the transfer part 410 moves to the inside of the two carriers 210, the delivery personnel can manually push or drive the driving device 1010 to drive the two carriers 210 to move towards each other, thereby switching from the release position to the carrying position. After the two carriers 210 cross each other to form the upward limiting groove 3, the transfer part 410 is lowered and placed in the limiting groove 3 (as shown in FIG. 7). In this way, the transfer part 410 of the goods 4 is directly used to limit the two carriers 210 in the carrying position, so as to realize the automatic locking of the two carriers 210 in the carrying position through the cooperation between the limiting groove 3 of the carrier 210 and the transfer part 410 of the goods 4, thereby effectively reducing the possibility of the goods 4 falling due to the disconnection of the two carriers 210 (switching from the carrying position to the release position) during the transportation of the goods 4, and improving the delivery quality and safety of the goods 4.

[0093] For example, when the two carriers 210 are in the carrying position, as shown in FIG. 5, the transfer part 410 of the goods 4 can be manually or by a mechanical arm or the like to the lower part of the two carriers 210, then the goods 4 are lifted and the transfer part 410 of the goods 4 is moved along the first guide surface 2121 of the movable arm 212 towards the two carrying arms 211, the two carrying arms 211 are rotated away from each other from the crossing position to the separated position (as shown in FIGS. 6 and 8) by pushing the two carrying arms 211 to overcome the elastic force of the torsional spring 2131 by moving the transfer part 410 of the goods 4, and when the transfer part 410 enters between the two carriers 210 and is separated from the two carrying arms 211 along the guide structure 8, the two carrying arms 211 are automatically reset to the crossing position under the elastic force of the torsional spring 2131, and then the transfer part 410 is lowered and placed in the limiting groove 3 (as shown in FIG. 7), so as to realize the purpose of automatically locking the two carriers 210 in the carrying position by the cooperation of the limiting groove 3 of the carrier 210 and the transfer part 410 of the goods 4, and at the same time, the position of the carrier 210 does not need to be switched, that is, even if the two carriers 210 are in the carrying position, the goods 4 can still be placed in the limiting groove 3 of the two carriers 210, which is convenient for the development of unmanned aerial vehicle distribution work.

[0094] It should be noted that the above-mentioned taking goods operation by controlling the unmanned aerial vehicle to descend is exemplary, for example, the unmanned aerial vehicle can also be stopped in the air, the motor 1011 of the driving device 1010 releases the flexible cable 1013, so that the suspension assembly moves and falls relative to the suspension main body 10 under the action of its own gravity, and it should be noted that during the process of releasing the flexible cable 1013, the two carriers 210 are switched to the release position (as shown in FIG. 4) under the elastic force of the second elastic reset member 7 because the flexible cable 1013 cannot provide pulling force, after the suspension assembly falls to the preset goods transfer position, the transfer part 410 of the goods 4 can be manually placed between the two carriers 210 by the delivery personnel, and the two carriers 210 are manually pressed, after the two carriers 210 are crossed to form the upward limiting groove 3 of the opening 310, the transfer part 410 is lowered and placed in the limiting groove 3, the two carriers 210 are limited in the carrying position by the transfer part 410 of the goods 4, and further, the suspension assembly is retracted into the channel 1021 of the box 1020 by winding the flexible cable 1013 by the motor 1011 of the driving device 1010, which is convenient for the development of subsequent goods 4 distribution work.

[0095] b. Unmanned aerial vehicle unloading:

[0096] After the unmanned aerial vehicle carrying the goods 4 flies to the preset position, the suspension assembly is in the first goods handover position. After the unmanned aerial vehicle is controlled to descend, the goods 4 are placed at the preset position. Further control of the unmanned aerial vehicle to descend causes the suspension assembly to move relative to the transfer part 410 of the goods 4, so that the transfer part 410 of the goods 4 is separated from the limiting groove 3. At this time, it is necessary to ensure that the flexible cable 1013 does not pull the actuating rod 6 or can gradually release the flexible cable 1013 during the movement of the two bearing members 210 away from each other. Thus, after the transfer part 410 of the goods 4 is separated from the limiting groove 3, the two bearing members 210 can switch to the release position (as shown in FIG. 4) under the elastic force of the second elastic return member 7. Then, the unmanned aerial vehicle is controlled to take off, and the distribution operation of placing the goods 4 at the preset position is completed.

[0097] The above operation of placing the goods 4 at the preset position by controlling the unmanned aerial vehicle to descend is exemplary. The unmanned aerial vehicle can also be stopped in the air, and the motor 1011 of the driving device 1010 releases the flexible cable 1013. Thus, the suspension assembly moves and falls relative to the suspension main body 10 under the action of its own gravity. During the process of releasing the flexible cable 1013, the two bearing members 210 switch to the release position (as shown in FIG. 4) under the elastic force of the second elastic return member 7, but the transfer part 410 of the goods 4 is placed in the limiting groove 3, so that the two bearing members 210 are still limited in the bearing position (as shown in FIG. 7). At this time, the compression spring 710 of the second elastic return member 7 is in a compressed state. After the goods 4 are placed at the preset position, the flexible cable 1013 is continuously released, which causes the suspension assembly to move relative to the transfer part 410 of the goods 4, so that the transfer part 410 of the goods 4 is separated from the limiting groove 3. Thus, after the limitation between the two bearing members 210 is released, the two bearing members 210 can move away from each other under the elastic force of the second elastic return member 7, so as to quickly switch to the release position (as shown in FIG. 4). Then, the flexible cable 1013 is wound, the suspension assembly is retracted into the passage 1021 of the box 1020, and the distribution operation of placing the goods 4 at the preset position is completed.

[0098] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept range of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection range of the present disclosure.

[0099] In addition, it should be noted that various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, various possible combinations are not described again in the present disclosure.

[0100] Furthermore, the various embodiments of the present disclosure can be combined with each other as long as they do not violate the idea of the present disclosure, and they should be considered as disclosed in the present disclosure.
