Description

Technical Field

[0001] This disclosure relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a UAV hook assembly and a UAV. Background Technology

[0002] Drone delivery is a significant trend in the logistics sector, widely used in scenarios such as express delivery and medical supply transportation. However, drone hook components in related technologies have significant shortcomings, requiring manual assistance for loading and unloading, which is cumbersome and inconvenient. Therefore, there is an urgent need for a drone hook component that can automatically load and release goods. Utility Model Content

[0003] The purpose of this disclosure is to provide a drone hook assembly and a drone to at least partially solve the problems existing in the related art.

[0004] To achieve the above objectives, this disclosure provides a drone hook assembly, including a base, a hook, and a locking component;

[0005] The hook is provided with a first rotating shaft and is rotatably connected to the base through the first rotating shaft; the hook has an unloaded state and a loaded state, and can rotate from the unloaded state to the loaded state under the push of the object to be loaded;

[0006] The locking member is provided with a second rotating shaft and is rotatably connected to the base through the second rotating shaft. The locking member is used to releasably restrict the hook to the mounted state.

[0007] Optionally, the hook includes a force-bearing finger, a locking part, and a mounting finger. The force-bearing finger, the locking part, and the mounting finger are integrally formed or fixedly connected to each other and arranged sequentially around the first rotating shaft in the circumferential direction. The force-bearing finger and the mounting finger form a first angle. A first elastic element is sleeved on the first rotating shaft. The first elastic element is used to rotate the hook toward the unloaded state.

[0008] Optionally, the locking member has a second elastic member for abutting the locking member against the hook to prevent the hook from rotating.

[0009] Optionally, the latching portion has a connected second arc segment and a straight segment, and the locking member has a connected first arc segment and a stop segment at the end near the hook. The second arc segment and the first arc segment have the same curvature. When the second arc segment and the straight segment are connected in sequence, the stop segment and the first arc segment are connected in sequence. When the straight segment and the second arc segment are connected in sequence, the first arc segment and the stop segment are connected in sequence.

[0010] Optionally, when the hook is in the unloaded state, the end of the hanging finger away from the first rotating shaft points downwards, and the second arc segment and the first arc segment abut against each other.

[0011] Optionally, when the object to be loaded pushes upward to rotate the hook in the loading state, the second arc segment slides relative to the first arc segment until the straight segment abuts against the top segment, thereby restricting the hook to the loading state;

[0012] In the mounted state, the end of the mounting finger away from the first rotating shaft is in a horizontal state or at a second angle to the horizontal state so that the object to be mounted is mounted on the mounting finger.

[0013] Optionally, the locking member further includes a release part for overcoming the second elastic member's obstruction of the hook's rotation, so that the straight segment slides away from the abutting segment, thereby allowing the hook to return to the unloaded state.

[0014] Optionally, there are two hooks, which are set at the same height position of the base in a mirror-symmetrical manner, so that in the loaded state, the loading fingers of the two hooks cooperate with each other to enclose the object to be loaded in the loading space formed by the two hooks;

[0015] Correspondingly, there are two locking components, which are used to simultaneously and releasably restrict the corresponding hooks to the mounted state.

[0016] Optionally, the first angle is a right angle; and / or, the first elastic element is a torsion spring; and / or, the second elastic element is a torsion spring sleeved on the second rotating shaft; or, when there are two locking elements, the second elastic element is a helical spring connected between the two locking elements; and / or, the second angle is less than a preset angle threshold.

[0017] According to a second aspect of this disclosure, a drone is provided, including the aforementioned drone hook assembly.

[0018] Using the above technical solution, when a load needs to be hooked and transported, the drone can be controlled to descend, causing the load to push the hook. This rotates the hook from an unloaded state to a loaded state via the first rotating shaft, and a locking device secures the hook in this loaded state to prevent it from rotating under the weight of the load, ensuring reliable hooking. When the load needs to be released after transport, the locking device is controlled to rotate via the second rotating shaft to release the hook from the loaded state. The load can then push the hook to rotate under its own weight, allowing it to detach from the hook. The entire loading and unloading process requires no manual intervention and eliminates the need for complex drone movements, making operation convenient and quick.

[0019] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0031] In this disclosure, unless otherwise stated, the directional terms “inner” and “outer” and “upper” and “lower” used may be defined based on the actual direction of use of the relevant components, or they may be based on their own structure. For example, “mounted” refers to the end away from the first pivot, and “downward” refers to the direction toward the ground. That is, “upper” and “lower” here correspond to the height direction perpendicular to the ground.

[0032] In addition, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0033] Reference Figures 1-3 This disclosure exemplarily illustrates a drone hook assembly, including a base 1, a hook 2, and a locking member 3. The hook 2 is provided with a first rotating shaft 61 and is rotatably connected to the base 1 via the first rotating shaft 61. The hook 2 has an unloaded state and a loaded state, and can rotate from the unloaded state to the loaded state under the push of a loading member 4. The locking member 3 is provided with a second rotating shaft 62 and is rotatably connected to the base 1 via the second rotating shaft 62. The locking member 3 is used to releasably restrict the hook 2 to the loaded state; that is, the locking member 3 can restrict the hook 2 to the position corresponding to the loaded state, and can also selectively release the hook 2 from that position to allow it to rotate freely. Of course, in some embodiments of this disclosure, the locking member 3 may also restrict the hook to the position corresponding to the unloaded state in the unloaded state so that it remains unloaded and can be pushed by the loading member 4 at any time. Of course, when the loading member 4 pushes the hook 2, the thrust can overcome the restriction of the locking member 3, or the locking member 3 may release the hook 2 when the loading member 4 pushes the hook 2. This disclosure does not limit this.

[0034] This disclosure does not limit the specific structure of the hook 2, as long as it can be rotated to the mounted state when pushed by the object to be loaded 4 in an unloaded state. The object to be loaded 4 refers to the object that needs to be hooked and transported by the drone, and it has Figures 1-6 The crossbar 41 (handle) shown is used to push the hook 2. This "pushing" can be achieved by the drone descending, during which the crossbar 41 rises relative to the drone, thereby pushing the hook 2. Alternatively, it can be achieved by other driving components pushing the loaded object 4 upward.

[0035] By using the above technical solution, when it is necessary to hook and transfer the load 4, the drone can be controlled to descend, causing the load 4 to push the hook 2, thereby rotating the hook 2 from an unloaded state to a loaded state via the first rotating shaft 61. The locking member 3 then restricts the hook 2 to this loaded state, preventing it from rotating under the weight of the load 4 and ensuring the reliability of hooking the load 4. When the load 4 needs to be released after transportation, the locking member 3 is controlled to rotate via the second rotating shaft 62 to release the hook 2 from the loaded state. Thus, the load 4 can push the hook 2 to rotate under gravity until it can detach from the hook 2. The entire loading and unloading process requires no manual intervention and does not require complex drone movements, making operation convenient and quick.

[0036] Reference Figures 4-6 In some embodiments of this disclosure, the hook 2 may include a force-receiving finger 21, a locking portion, and a mounting finger 22. The force-receiving finger 21, the locking portion, and the mounting finger 22 may be integrally formed or fixedly connected to each other, and arranged sequentially around the first rotating shaft 61 in a circumferential direction, so that when the hook 2 rotates, the force-receiving finger 21, the locking portion, and the mounting finger 22 can rotate accordingly to achieve a change in working state. The force-receiving finger 21 and the mounting finger 22 may be at a first angle. A first elastic element 51 may be sleeved on the first rotating shaft 61, which is used to rotate the hook 2 to an unloaded state. With this design, in the unloaded state, the load-bearing item 4 can push the force-receiving finger 21 to make the mounting finger 22 rotate around the first rotating shaft 61 to a mounting state, and the locking 3 cooperates with the locking portion to limit it to this state. When unloading is required, the locking element 3 can release the hook 2 from the mounting state, and the first elastic element 51 can reset the hook 2 to the unloaded state. The hook 2 is designed with the aforementioned structure to achieve the aforementioned technical effects in the simplest possible way, reducing production costs and technical difficulties. By setting the first elastic element 51, when the weight of the load 4 is too small to drive the hook 2 to rotate by gravity, the first elastic element 51 can assist in driving the hook 2 to rotate, ensuring that the load 4 can be smoothly detached from the hook. Furthermore, setting the first elastic element 51 can meet the unloading needs of more scenarios. For example, when the load 4 is in the unloading position, that is, when there is support on the lower side and it cannot move downwards, the first elastic element 51 can drive the hook 2 to rotate, and when it rotates to avoid the load 4, it can drive the drone to rise to complete the unloading.

[0037] This disclosure does not limit the first angle. For example, in some embodiments, the first angle can be a right angle. Of course, the right angle here does not have to be absolutely equal to 90 degrees, as long as it is close to a right angle in general, such as 70°-110°.

[0038] This disclosure does not limit the first elastic element 51, for example in Figures 4-6In the illustrated embodiment, the first elastic element 51 can be a torsion spring sleeved on the first rotating shaft 61. By providing the torsion spring, when the hook 2 rotates from the unloaded state to the loaded state, the torsion spring can be twisted to have a restoring force, so that when the hook 2 is released from the loaded state, the torsion spring can drive the hook 2 to rotate to the unloaded state. In addition, in some other embodiments, the first elastic element may also include a spring, rubber strip, etc. connected between the base 1 and the hook 2, as long as it can generate a restoring force when the hook 2 rotates from the unloaded state to the loaded state, so that when the hook 2 is released from the loaded state, the restoring force can drive the hook 2 to rotate to the unloaded state.

[0039] Specifically Figures 4-6 In the illustrated embodiment, the force-bearing finger 21 and the mounting finger 22 can be connected to form a T-shaped structure. In the unloaded state, the mounting finger 22 avoids the load-bearing member 4, allowing the load-bearing member 4 to move upward and push the force-bearing finger 21, thereby causing the mounting finger 22 to rotate to the underside of the load-bearing member 4 to achieve hooking. In addition, in some other embodiments, the force-bearing finger 21 and the mounting finger 22 can also be connected to form an L-shaped structure, which is not limited in this disclosure.

[0040] Reference Figures 4-6 In some embodiments of this disclosure, the locking member 3 may have a second elastic member 52, which can be used to abut the locking member 3 against the hook 2 to prevent the hook 2 from rotating. By designing the second elastic member 52, when the hook 2 rotates to the loaded state, it can drive the locking member 3 to rotate to abut against the hook 2 to restrict the rotation of the hook 2 and keep it in the loaded state. In the unloaded state and during the process of rotating from the unloaded state to the loaded state, the second elastic member may not have elasticity, or it may have elasticity, but the locking member 3 can be restricted from rotating under the action of the elasticity until the hook 2 rotates to the loaded state, at which point the elasticity of the second elastic member 52 takes effect.

[0041] This disclosure does not limit the second elastic element 52, for example in Figures 4-6 In the illustrated embodiment, the second elastic element 52 can be fitted onto the torsion spring of the second rotating shaft 62. By providing the torsion spring, it is configured to have elasticity in the initial position. This elasticity can be used to press the two arc segments (the first arc segment and the second arc segment, mentioned below) together when the hook 2 rotates, and to quickly drive the locking element 3 to rotate to restrict the hook 2 to the loading state when the hook 2 rotates to the loading state (the two arc segments are staggered). In addition, in some other embodiments, the second elastic element 52 may also include a spring, rubber strip, etc., connected between the base 1 and the locking element 3, as long as it can have elasticity and achieve the aforementioned technical effects.

[0042] This disclosure does not limit the specific structure of the hook 2 and the locking element 3, or their mating relationship. (Refer to...) Figures 4-6 In some embodiments of this disclosure, the engaging portion may have a connected second arc segment 201 and a straight segment 202, and the end of the locking member 3 near the hook 2 may have a connected first arc segment 301 and abutting segment 302. The second arc segment 201 and the first arc segment 301 have the same curvature to ensure that the two arc segments do not interfere with the rotation of the hook 2 when they are in contact, and that when the two arc segments are offset, the locking member 3 only requires a small rotation angle to move to the locking state.

[0043] In some embodiments of this disclosure, when the second arc segment 201 and the straight line segment 202 are connected sequentially, the abutting segment 302 and the first arc segment 301 are connected sequentially. See [link to specific embodiments]. Figures 4-6 A set of locking components 3 and hooks 2 are located on the left side of the drawing. When the straight segment 202 and the second arc segment 201 are connected sequentially, the first arc segment 301 and the abutment segment 302 are connected sequentially. See [reference needed] for details. Figures 4-6 A set of locking components 3 and hooks 2 are located on the right side of the drawing. Here, "sequential connection" refers to... Figures 4-6 The two segments in the diagram are connected sequentially from left to right, so that the first arc segment 301 and the second arc segment 201 correspond to each other. When the hook 2 rotates at a certain angle to become a loaded state, the straight segment 202 can cooperate with the abutment segment 302 to stop and restrict the rotation of the hook 2.

[0044] Reference Figures 4-6 In some embodiments of this disclosure, when the hook 2 is in an unloaded state, the end of the mounting finger 22 away from the first rotating shaft 61 can point downwards, and the second arc segment 201 and the first arc segment 301 can abut against each other. With this design, when the hook 2 needs to rotate from an unloaded state to a mounted state, the two arc segments slide against each other without causing rotational interference, thus ensuring that the hook 2 can smoothly rotate to the mounted state under the push of the load-bearing member 4. Furthermore, in the unloaded state, the end of the mounting finger 22 away from the first rotating shaft 61 points downwards and does not have a mounting function, thus avoiding the installation path of the load-bearing member 4, allowing the load-bearing member 4 to push the force-bearing finger 21 to drive the mounting finger 22 to rotate to the mounted state.

[0045] Reference Figures 4-6In some embodiments of this disclosure, when the component to be loaded 4 pushes the force-bearing finger 21 upward to rotate towards the loading state of the hook 2, the second arc segment 201 slides relative to the first arc segment 301 until the straight segment 202 abuts against the abutting segment 302, thereby restricting the hook 2 to the loading state. In the loading state, the end of the loading finger 22 away from the first rotating shaft 61 is in a horizontal state or at a second angle to the horizontal state so that the component to be loaded 4 is loaded onto the loading finger 22. Specifically, when the hook 2 rotates from the unloaded state to the loaded state, the first arc segment 301 and the second arc segment 201 slide against each other. During this process, the second elastic element 52 can drive the first arc segment 301 to press against the second arc segment 201, and the locking element 3 cannot rotate. When the second arc segment 201 rotates to the point where it is offset from the first arc segment 301, the hook 2 rotates to the loaded state. The second elastic element 52 can drive the locking element 3 to rotate until the abutting segment 302 can form an abutting relationship with the straight segment 202, thereby restricting the rotation of the hook 2. That is, the locking element 3 can restrict the hook 2 from reversing to the unloaded state under the gravity of the load-bearing element 4 and the elastic force of the first elastic element 51.

[0046] This disclosure does not impose any restrictions on the second angle, as long as it can satisfy the requirement that the mounting finger 22 can hook onto the load 4 from below in the mounting state. That is, the second angle can be less than a preset angle threshold, thereby ensuring that the end of the mounting finger 22 away from the first rotating shaft 61 can be approximately horizontal (if the angle is too large, it may not be able to hold the load 4, and the load 4 will slide off). The preset angle threshold can be 10°, 20°, etc., and can be adapted to actual needs.

[0047] Reference Figures 4-6 In some embodiments of this disclosure, the locking member 3 may further include a release part (not shown in the figure). The release part can be used to overcome the obstruction of the second elastic member 52 to the rotation of the hook 2, so that the straight segment 202 can slide off the abutting segment 302, allowing the hook 2 to return to an unloaded state. With this design, when it is necessary to release the hook 2 for unloading, the release part can drive the locking member 3 to rotate against the elastic force of the second elastic member 52 until the hook 2 can rotate to an unloaded state under the action of the aforementioned first elastic member 51 or the gravity of the load 4, so as to allow the load 4 to disengage from the hook 2 to complete the unloading.

[0048] This disclosure does not limit the release part; for example, the release part can be a drive motor connected to the second rotating shaft 62.

[0049] Reference Figures 4-6In some embodiments of this disclosure, there may be two hooks 2, which are mirror-symmetrically positioned at the same height on the base 1. This allows the hooking fingers 22 of the two hooks 2 to cooperate in the loading state, enclosing the object to be loaded 4 within the loading space formed by the two hooks 2. Here, it should be explained that "mirror-symmetry" means that the openings of the two hooks 2 face each other. Thus, when simultaneously pushed by the object to be loaded 4, the hooking fingers 22 of the two hooks 2, used to hook the object to be loaded 4, can move simultaneously from both sides towards the center until they approach or contact each other, thereby achieving simultaneous hooking of the object to be loaded 4 from below. This design, by using the two hooks 2 to enclose the object to be loaded 4 within the loading space in the loading state, prevents it from detaching from the hooks 2, improving the reliability of loading and transportation.

[0050] Specifically, when the two hooks 2 respectively have the aforementioned mounting finger 22 and force-bearing finger 21, refer to Figures 4-6 In the unloaded state, the two force-bearing fingers 21 cross each other and are centered so that they can be pushed simultaneously by the object to be loaded 4; the two mounting fingers 22 are far apart from each other and located on both sides of the movement path of the object to be loaded 4, so that the object to be loaded 4 can move upward from the middle of the two mounting fingers 22 to push the force-bearing fingers 21, so that the two mounting fingers 22 can rotate to hook the object to be loaded 4 from the bottom side together, so as to prevent it from falling off the hook 2.

[0051] Correspondingly, when the number of hooks 2 is two, refer to Figures 4-6 In some embodiments of this disclosure, there may be two locking members 3, used to simultaneously and releasably restrict the corresponding hooks 2 to the mounted state. The two locking members 3 may be rotatably mounted on the base 1 via the aforementioned second pivot 62 and act on the corresponding hooks 2.

[0052] Reference Figures 4-6 In some embodiments of this disclosure, when there are two locking members 3, the second elastic member 52 can be a helical spring 53 connected between the two locking members 3. In the unloaded state, the helical spring 53 can elastically abut against the two locking members 3, causing the locking members 3 to have a rotational tendency (i.e., the aforementioned two arc segments abut against each other). When the hook 2 rotates to the loaded state, the helical spring 53 can simultaneously drive the two locking members 3 to rotate, thereby restricting the hook 2 to the loaded state. Of course, when there are two locking members 3, the second elastic member 52 can also be a torsion spring acting on the corresponding locking member 3, and this disclosure does not limit this. Figures 4-6 In the illustrated embodiment, the second elastic element 52 includes both a torsion spring and a coil spring to improve the reset effect. In fact, in some other embodiments, only one of the two may be present.

[0053] According to a second aspect of this disclosure, a drone is provided, including the aforementioned drone hook assembly, since the drone has all the beneficial effects of the aforementioned drone sling assembly, which will not be described in detail here.

[0054] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0055] It should also be noted that the 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, this disclosure will not describe the various possible combinations separately.

[0056] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
