Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV unhooking device. Background Technology

[0002] Unmanned vehicles, or URMs for short, are devices operated by radio remote control equipment and their own program control devices, or by an onboard computer that operates them completely or intermittently autonomously. These include unmanned aerial vehicles, unmanned vehicles, and robot dogs.

[0003] With the widespread application of drone technology in various fields, in rescue and emergency response scenarios, such as disaster relief and material delivery, drones typically use a release device to suspend first aid kits, communication equipment or other rescue supplies, and release the load after reaching the designated location to achieve rapid and efficient rescue operations.

[0004] Currently, drone unhooking devices typically employ mechanical locking structures, such as a method where the hook is rotated and engages with a limiting post after hoisting. However, when not in use, the hook of existing drone unhooking devices often droops due to gravity and enters the hook's interior, which can easily affect the hook's normal closure. Alternatively, to prevent the hook from interfering with hook closure, an unnecessary operation is performed to move the hook to one side before hoisting, which is cumbersome and inconvenient to use. Utility Model Content

[0005] This utility model proposes a drone unhooking device, which solves the problem in the existing drone unhooking devices in related technologies that, when not in use, the hook usually rotates and droops due to gravity and enters the hook, which can easily affect the normal closure of the hook, or require the unnecessary operation of moving the hook to one side before hoisting.

[0006] The technical solution of this utility model is as follows: a drone unhooking device, comprising: two main connecting rods that are rotatably connected to each other;

[0007] Two hooks are provided below the two main connecting rods and are arranged in a cross manner. The top of the two hooks and the bottom of the two main connecting rods are provided with a through hole one, and the intersection of the two hooks is provided with a through hole two.

[0008] A connecting component 1, installed in the through hole 1, is used to rotatably connect the main connecting rod and the hook.

[0009] A connecting piece 2 is installed inside the through hole 2 to allow the two hooks to rotate relative to each other;

[0010] A limiting post is fixedly installed on one side of a main connecting rod;

[0011] A hook plate is rotatably connected to one side of another main body connecting rod, and the hook plate cooperates with the limiting post to limit the movement;

[0012] A circular stop block fixedly installed on one side of a main connecting rod and located below the hook plate;

[0013] And a tension spring located between the main connecting rod and the hook.

[0014] Preferably, the hook plate is T-shaped, and the corners of the vertical and horizontal sections of the hook plate are rounded.

[0015] Preferably, a gripping block is rotatably mounted on one side of the hook plate, and a limit block is fixedly mounted on one side of the hook.

[0016] Preferably, one of the main connecting rods has a protruding ring 1 integrally formed, and one of the hooks has a protruding ring 2 integrally formed, with the two ends of the tension spring connected to the protruding ring 1 and the protruding ring 2 respectively.

[0017] Preferably, the connector includes a pin rod with a T-shaped cross-section that passes through the through hole, an annular groove formed on one end surface of the pin rod, and an annular pad that is engaged in the annular groove, wherein the annular pad has a notch for easy engagement.

[0018] Preferably, the second connector has the same structure as the first connector.

[0019] Preferably, a connecting ring is rotatably installed at the connection point of the two main connecting rods.

[0020] The working principle and beneficial effects of this utility model are as follows:

[0021] During hoisting, the main connecting rod and the hook rotate relative to each other and close, while the tension spring is stretched. Then, the hook plate and the limiting post are rotated to overlap and limit the movement. When unloading the item, the hook plate is reversed and separated from the limiting post. Only then can the main connecting rod and the hook rotate and open due to the elastic force of the tension spring. The hook plate can then overlap the circular stop, which blocks it and limits the rotation range of the hook plate. This prevents the hook plate from entering the hook and avoids the hook plate rotating too downward, which would affect the closure of the hook. Furthermore, it eliminates the need for extra operations to adjust the position of the hook plate, effectively improving the use and operation convenience of the unhooking device.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0029] Please see Figure 1 - Figure 4 The drone unhooking device provided by this utility model includes: two main connecting rods 1 that are rotatably connected to each other;

[0030] Two hooks 2 are located below the two main connecting rods 1 and are arranged in a cross configuration. The top of the two hooks 2 and the bottom of the two main connecting rods 1 are both provided with a through hole 1, and a through hole 2 is provided at the intersection of the two hooks 2.

[0031] A connecting piece 1 is installed in the through hole 1 to allow the main connecting rod 1 and the hook 2 to rotate and connect;

[0032] A connecting piece 2 is installed inside the through hole 2 to allow the two hooks 2 to rotate relative to each other;

[0033] A limiting post 3 is fixedly installed on one side of a main connecting rod 1;

[0034] The hook plate 4 is rotatably connected to one side of another main body connecting rod 1, and the hook plate 4 and the limiting post 3 cooperate to limit the movement;

[0035] A circular stop 6 is fixedly installed on one side of a main connecting rod 1 and located below the hook plate 4;

[0036] And a tension spring 7 located between the main connecting rod 1 and the hook 2.

[0037] The hook plate 4 is T-shaped, and the corners of the vertical and horizontal sections of the hook plate 4 are rounded. The hook plate 4 is engaged with the limiting post 3 through the rounded corners.

[0038] The technical solution provided in this embodiment is as follows: In use, two hooks 2 are cross-connected together by connector two, and then the main connecting rod 1 and hooks 2 are connected by connector one. Later, connector one and connector two can be detached to separate the main connecting rod 1 and hooks 2 for maintenance. When not hoisting, hooks 2 are in the open state, hook plate 4 and limit post 3 are separated, and tension spring 7 is in a compressed state. During hoisting, the hoisting part of the item to be hoisted is placed between the two hooks 2, and the device is moved upward by a drone. The two main connecting rods 1 rotate relative to each other and close. Under the action of connector one and connector two, the two hooks 2 rotate and close with the rotation of the main connecting rod 1, simultaneously stretching the tension spring 7, thereby hoisting the item. Afterwards, the device rotates... The hook plate 4 and the limiting post 3 overlap and are fixed by the arc part of the hook plate 4 and the limiting post 3, so as to fix the closed state of the hook 2 and prevent the hook 2 from accidentally opening during the hoisting process and causing the hoisted object to fall. When unloading the object, the hook plate 4 is separated from the limiting post 3 by reversing the hook plate 4 again. The tension spring 7 can then cause the main connecting rod 1 and the hook 2 to rotate and open. The hook plate 4 can overlap the circular stop 6, so that the circular stop 6 blocks it and limits the rotation range of the hook plate 4. Therefore, the hook plate 4 is prevented from entering the hook 2. This avoids the hook plate 4 rotating downward too much and affecting the closure of the hook 2. There is no need to perform extra operations to adjust the position of the hook plate 4, which effectively improves the use effect and operation convenience of the unhooking device. Furthermore, when this unhooking device is closed, the hook plate 4 and the limiting post 3 can have two different limiting states. The first state is that the hook plate 4 hooks the limiting post 3 from above, that is, the hook plate 4 is above the limiting post 3. The second state is that the hook plate 4 hooks the limiting post 3 from below, that is, the hook plate 4 is below the fiber paper 3. When the first state is closed, it can prevent the suspended object from falling. When the suspended object is lowered, the unhooking device needs to be opened manually. When the suspended object is lowered in the second state, the unhooking device can automatically unhook under the action of elasticity without human intervention, which saves manpower.

[0039] It should be noted that when the second state is in the limit position, the hook plate 4 should be rotated from the top to the side of the limit post 3 before the unhooking device closes. When closed, the hook plate 4 is located below the limit post 3. Rotating the hook plate 4 upwards will allow it to hook the limit post 3 with the help of the arc design and the elastic force. When the load is lowered, the unhooking device can automatically open with the help of the elastic force.

[0040] Furthermore, a gripping block 5 is rotatably mounted on one side of the hook plate 4, and a limit block 10 is fixedly mounted on one side of the hook 2.

[0041] Specifically, by setting the gripping block 5, when rotating the hook plate 4, the gripping block 5 can be held to drive the hook plate 4 to rotate, which is convenient for operation and use. By using the limiting block 10, the rotation angle range between the main connecting rod 1 and the hook 2 can be limited, thereby limiting the opening and closing angle of the hook 2 and avoiding the situation where the opening angle of the hook 2 is too large, causing the device structure to be unstable.

[0042] Furthermore, a convex ring 8 is integrally formed on a main connecting rod 1, and a convex ring 9 is integrally formed on a hook 2. The two ends of the tension spring 7 are connected to the convex ring 8 and the convex ring 9 respectively.

[0043] Specifically, by setting convex ring 8 and convex ring 9, it is convenient to install tension spring 7, and convex ring 8 and convex ring 9 are set at an angle to each other to facilitate the optimization of force distribution.

[0044] Furthermore, the connector includes a pin 11 that passes through the through hole and has a T-shaped cross-section, an annular groove 13 formed on one end surface of the pin 11, and an annular pad 12 that is engaged in the annular groove 13. The annular pad 12 has a notch 14 for easy engagement.

[0045] Specifically, when connecting the main body connecting rod 1 and the hook 2, the main body connecting rod 1 and the hook 2 are aligned so that the through holes are aligned. Then, the pin rod 11 is passed through the first through hole, and the annular washer 12 passes through the notch 14 and the annular groove 13. This allows the annular washer 12 and the annular groove 13 to engage and fix the pin rod 11, thus achieving the function of connecting the main body connecting rod 1 and the hook 2. Conversely, the annular washer 12 is removed from the annular groove 13, and then the pin rod 11 is pulled out to separate the main body connecting rod 1 and the hook 2. This allows for the connection and disassembly of the main body 1 and the hook 2, facilitating subsequent individual replacement and maintenance of the main body connecting rod 1 or the hook 2, and making it convenient for future use.

[0046] Furthermore, the structure of connector two is the same as that of connector one.

[0047] Specifically, by setting up connector 2, it is easy to connect the two hooks 2 to each other by rotation, and it is also easy to disassemble the two hooks 2 for subsequent replacement and maintenance.

[0048] Furthermore, a connecting ring 15 is rotatably installed at the connection point of the two main connecting rods 1.

[0049] Specifically, by setting up a connecting ring 15, it is easy to connect this device to the drone. The connecting ring 15 is rotatably installed, so when the drone is flying, this device can be tilted relative to the drone, which makes it easy to adjust the angle of rotation according to the drone's flight, thus reducing flight resistance.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
