A pipe fitting is disposed on the other side of the mounting slot and movably connected to the base. When the pipe fitting is in the first working position, the first end of the pipe fitting is tightly fitted with the mounting component to restrict the mounting component from rotating in the second direction. When the pipe fitting leaves the first working position, the first end of the pipe fitting separates from the mounting component to release the restriction on the mounting component. A braking element is disposed on the side of the pipe away from the mounting element and hinged to the base.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In related technologies, the unhooking mechanism of drones is often complex in structure and large in size, which increases the manufacturing cost. Moreover, with long-term use, the reliability of attachment and unhooking deteriorates, affecting the overall performance and maneuverability of the drone.

[0022] In view of this, embodiments of this application provide a drone unhooking device.

[0023] See Figure 1 A drone unhooking device, comprising: The base 1 is provided with a mounting slot 100, and the opening end of the mounting slot 100 faces downward. The mounting component 4 is disposed on one side of the mounting slot 100. One end of the mounting component 4 is hinged to the base 1. The other end of the mounting component 4 can rotate around the hinge center in a first direction to close the opening end of the mounting slot 100, or rotate in a second direction to open the opening end of the mounting slot 100. Pipe 5 is disposed on the other side of the mounting slot 100 and movably connected to the base 1. When the pipe 5 is in the first working position, the first end of the pipe 5 is tightly engaged with the mounting member 4 to restrict the mounting member 4 from rotating in the second direction. When the pipe 5 leaves the first working position, the first end of the pipe 5 is separated from the mounting member 4 to release the restriction on the mounting member 4. Braking element 6 is disposed on the side of the pipe 5 away from the mounting element 4 and hinged to the base 1. Braking element 6 can engage with the second end of the pipe 5 to lock the pipe 5 in the first working position. Servo motor 2 is mounted on the base 1. The output shaft of servo motor 2 is connected to servo motor arm 3. Servo motor arm 3 is connected to brake element 6. Servo motor 2 is used to drive brake element 6 to rotate to release the position lock of brake element 6 on tube 5.

[0024] For details, see Figure 1 and Figure 2 The base 1 serves as the mounting base for installing the servo motor 2, the mounting bracket 4, the tubing 5, and the brake component 6. The base 1 is connected to the UAV body, enabling the entire UAV unhooking device to be mounted on the UAV. In this embodiment, the base 1 includes a detachably connected upper cover 11 and a lower cover 12. A receiving cavity is formed in the lower cover 12, and the servo motor 2, the mounting bracket 4, the tubing 5, and the brake component 6 are all installed in the receiving cavity. The upper cover 11 is used to close the receiving cavity to protect the internal core components.

[0025] A U-shaped mounting slot 100 is provided at the bottom of the base 1, with the open end of the mounting slot 100 facing downwards, for mounting external materials. A mounting component 4 is installed on one side of the mounting slot 100. One end of the mounting component 4 is hinged to the lower cover 12 of the base 1, and the other end of the mounting component 4 is a free end, capable of rotating around the hinge center. The length of the mounting component 4 is greater than the length of the open end of the mounting slot 100. By rotating the mounting component 4, the open end of the mounting slot 100 can be sealed or exposed. For details, see [link to documentation]. Figure 2 and Figure 3 When the mounting component 4 rotates clockwise (i.e., in the first direction), the mounting component 4 closes the mounting slot 100. When the mounting component 4 rotates counterclockwise (i.e., in the second direction), the mounting component 4 opens the mounting slot 100.

[0026] The fitting 5 is installed on the side of the mounting slot 100 away from the mounting member 4. The fitting 5 can move relative to the base 1, and the movement state of the mounting member 4 can be controlled by changing its position. Specifically, when the fitting 5 is in the first working position, the first end of the fitting 5 can be tightly engaged with the free end of the mounting member 4, restricting the mounting member 4 from rotating in the second direction, that is, restricting the mounting member 4 from rotating in the direction of opening the mounting slot 100, ensuring that the mounting slot 100 is in a stable closed state and preventing materials from accidentally falling off; when the fitting 5 leaves the first working position, the first end of the fitting 5 separates from the free end of the mounting member 4, and the mounting member 4 loses the constraint of the fitting 5, and can rotate around the hinge center in the second direction, thereby opening the open end of the mounting slot 100 and realizing the unhooking of the materials.

[0027] The brake element 6 is located on the side of the pipe 5 away from the hanger 4 and is hinged to the lower cover 12 of the base 1. The brake element 6 can engage with the second end of the pipe 5. When the brake element 6 engages with the pipe 5, the pipe 5 can be locked in the first working position, thereby ensuring that the hanger 4 is always restricted by the pipe 5 and maintaining the closure of the hanger slot 100.

[0028] The servo motor 2 is mounted on the base 1, and its output shaft is connected to the servo motor arm 3. The servo motor arm 3 is connected to the brake element 6. The servo motor 2 can precisely control the rotation of the brake element 6. By driving the brake element 6 to rotate, the second end of the brake element 6 can be separated from the second end of the pipe 5, thereby releasing the position lock of the pipe 5. After the pipe 5 loses the force of the brake element 6, it will leave the first working position, thereby releasing the constraint on the free end of the mounting member 4, realizing the opening of the mounting slot 100, and completing the unhooking of the material.

[0029] Therefore, through the cooperation of servo motor 2, servo motor arm 3, brake component 6, pipe component 5 and mounting component 4, the opening and closing of the mounting slot 100 can be realized. Compared with the traditional unhooking mechanism, the entire device has a simple and compact structure, reduces unnecessary complex structures and the number of parts, can achieve lightweighting, reduces manufacturing costs, and also reduces the risk of failure caused by too many complex parts. The mounting and unhooking operations are more stable and reliable.

[0030] Optionally, the pipe 5 is hinged to the base 1. When the pipe 5 is in the first working position, the pipe 5 is in a horizontal state, the brake 6 is in a vertical state, the first end of the pipe 5 is located below the hanger 4 and is tightly engaged with the hanger 4, and the second end of the pipe 5 is engaged with the brake 6.

[0031] Specifically, in this embodiment, the pipe 5 is hinged to the lower cover 12 of the base 1, see [reference]. Figure 2 When the device is in the mounted state, pipe fitting 5 is in the first working position, pipe fitting 5 is in a horizontal state, and braking component 6 is located on the left side of pipe fitting 5 and is in a vertical state. The first end of pipe fitting 5, i.e. Figure 2 The right end of the pipe fitting 5 shown is located below the hanger 4 and is tightly fitted against the hanger 4, restricting the hanger 4 from rotating in the second direction, i.e., counterclockwise; the second end of the pipe fitting 5, i.e. Figure 2 The left end of the tube 5 shown is engaged with the bottom end of the brake 6, restricting the tube 5 from rotating in the first direction, i.e., clockwise.

[0032] When the servo motor 2 drives the brake 6 to rotate clockwise, the bottom end of the brake 6 separates from the left end of the tube 5. The tube 5 will rotate clockwise under the action of gravity, releasing the restriction on the mounting piece 4. The mounting piece 4, without the constraint of the tube 5, will rotate counterclockwise under the action of gravity, thus opening the opening end of the mounting slot 100.

[0033] To ensure that after the brake element 6 separates from the tube 5, the tube 5 can automatically rotate clockwise to leave the first working position, the center of gravity of the tube 5 should be located at its right end, that is, the second end that mates with the mounting element 4. As an optional implementation, in this embodiment, the length from the right end of the tube 5 to the hinge center is greater than the length from the left end of the tube 5 to the hinge center, so that after the tube 5 loses the constraint of the brake element 6, the heavier right end will automatically rotate clockwise around the hinge center. In other embodiments, the weight of the right end of the tube 5 can also be increased by adding counterweights.

[0034] Optionally, a tension spring 7 is provided on the base 1, and the tension spring 7 and the servo arm 3 are respectively located on both sides of the brake member 6; the middle part of the brake member 6 is hinged to the base 1, the first end of the brake member 6 is connected to the servo arm 3 through a pull rope 8, the first end of the brake member 6 is connected to the base 1 through the tension spring 7, and the second end of the brake member 6 is engaged with the second end of the tube 5; the servo arm 3 is used to drive the brake member 6 to rotate in a first direction so that the second end of the brake member 6 is separated from the second end of the tube 5, and the tension spring 7 is used to drive the brake member 6 to rotate and reset in a second direction.

[0035] See Figure 2 The tension spring 7 is located on the left side of the brake component 6. One end of the tension spring 7 is connected and fixed to the lower cover 12 of the base 1 through a mounting post, and the other end of the tension spring 7 is connected and fixed to the upper end of the brake component 6. The servo arm 3 is located on the right side of the brake component 6. The servo arm 3 is connected to the upper end of the brake component 6 through a pull rope 8, which is a steel wire rope. When the device is in the mounted state, the brake component 6 is in a vertical state. The tension of the tension spring 7 can provide a preload force to the upper left of the brake component 6, so that the pull rope 8 is taut between the servo arm 3 and the upper end of the brake component 6. At the same time, it ensures that the lower end of the brake component 6 is tightly engaged with the left end of the tube 5, preventing the tube 5 from rotating clockwise and ensuring that the mounting slot 100 is stably closed.

[0036] See Figure 3 When the servo motor 2 drives the servo motor arm 3 to rotate counterclockwise, the pull rope 8 pulls the upper end of the brake 6 to move to the right. Simultaneously, the tension spring 7 is stretched, and the brake 6 rotates clockwise around the hinge center, causing the lower end of the brake 6 to separate from the left end of the tube 5, releasing the lock on the tube 5, and thus releasing the rotation restriction on the mounting member 4, enabling the opening of the mounting slot 100. (See also...) Figure 4 After the mounting slot 100 is opened, the servo motor 2 drives the servo motor arm 3 to rotate clockwise back to the initial position. At this time, the elastic force of the tension spring 7 will pull the upper end of the brake 6 to move to the left to reset, so that the brake 6 rotates counterclockwise around the hinge center back to the vertical state, thereby resetting the brake 6 and preparing for the next mounting operation.

[0037] By using the tension spring 7, the pull rope 8, and the servo arm 3 to control the rotation of the brake 6, the entire unhooking process becomes more stable and reliable. The preload of the tension spring 7 not only ensures the tight engagement between the brake 6 and the tube 5, but also accurately drives the brake 6 to reset after the servo arm 3 moves, thus improving the repeatability and durability of the device.

[0038] Optionally, the second end of the pipe fitting 5 is provided with a snap-fit ​​groove 51, the shape of which is adapted to the shape of the second end of the brake member 6.

[0039] like Figure 2 As shown, a snap-fit ​​groove 51 is provided at the left end of the pipe fitting 5. The shape of the snap-fit ​​groove 51 is adapted to the shape of the lower end of the brake member 6, ensuring that the brake member 6 can be firmly snapped into the snap-fit ​​groove 51 of the pipe fitting 5, further enhancing the locking effect of the brake member 6 on the pipe fitting 5.

[0040] Optionally, the distance from the second end of the pipe 5 to the hinge center of the pipe 5 is greater than the horizontal distance between the hinge center of the pipe 5 and the hinge center of the brake 6.

[0041] Specifically, in this embodiment, the second end of the brake 6 is snapped onto the upper side of the second end of the pipe 5. To ensure a tight and secure snapping, the distance from the end of the second end of the pipe 5 to its hinge center (i.e., the arm length of the second end of the pipe 5) is greater than the horizontal distance between the hinge center of the pipe 5 and the hinge center of the brake 6, so as to prevent the arm length of the second end of the pipe 5 from being too short to contact the brake 6, and to ensure that the pipe 5 can be smoothly snapped onto the brake 6 in a horizontal state.

[0042] Optionally, the second end of the pipe fitting 5 is provided with an arc shape, and the second end of the brake member 6 is provided with an arc-shaped surface on the side facing the pipe fitting 5.

[0043] Specifically, Figure 4 This diagram shows the device in the mounted state, with the servo arm 3 driving the brake 6 back to a vertical position. At this time, the mounting slot 100 is open, and both the tube 5 and the mounting member 4 are in a naturally hanging, i.e., vertical, position. When a heavy object needs to be mounted again, the mounting rope must first be placed into the mounting slot 100, then the mounting member 4 is rotated clockwise to a horizontal position, and then the tube 5 is rotated counterclockwise to a horizontal position. Because the arm length of the second end of the tube 5 is greater than the horizontal distance between the hinge center of the tube 5 and the hinge center of the brake 6, during the counterclockwise rotation of the tube 5 from a vertical to a horizontal position, the second end of the tube 5 will abut against the second end of the brake 6, overcoming the elastic force of the tension spring 7 and pushing the second end of the brake 6 to the left. Figure 5As shown, the brake 6 rotates clockwise by a certain angle under the resistance of the tube 5, during which the tension spring 7 is stretched. When the tube 5 rotates to the moment it separates from the brake 6, the brake 6, which has lost the resistance of the tube 5, will rotate counterclockwise under the elastic force of the tension spring 7 and quickly engage in the locking groove 51 at the second end of the tube 5, making a collision sound, thus locking the tube 5 and closing the mounting slot 100, thereby realizing the mounting of the heavy object.

[0044] The second end of the pipe fitting 5 is set to be arc-shaped, and an arc-shaped surface is set on the side of the second end of the brake 6 facing the pipe fitting 5. Through the smooth arc surface cooperation, the pipe fitting 5 can make more smooth contact with the brake 6 during the process of rotating to the horizontal position, thereby reducing the action resistance of the loading operation and avoiding the impact of jamming or jamming during contact on the smooth progress of the loading operation.

[0045] Optionally, the base 1 has a hook-off hole 101 at the bottom of one side where the mounting slot 100 is located. The length of the hook-off hole 101 is greater than the distance between the hinge center of the pipe 5 and the hinge center of the mounting member 4, and the width of the hook-off hole 101 is greater than the thickness of the pipe 5 and the mounting member 4.

[0046] Specifically, since the mounting component 4 and the pipe component 5 rotate during mounting and unmounting, a unmounting hole 101 is provided at the bottom of one side of the base 1 where the mounting slot 100 is located to avoid interference with the base 1 during rotation. The length of the unmounting hole 101 is greater than the distance between the hinge center of the pipe component 5 and the hinge center of the mounting component 4, and the width of the unmounting hole 101 is greater than the thickness of both the pipe component 5 and the mounting component 4. This ensures that the mounting component 4 and the pipe component 5 have sufficient space to complete their respective actions during rotation. Furthermore, in the mounted state, both the mounting component 4 and the pipe component 5 can naturally fall off the base 1 through the unmounting hole 101, allowing the mounting slot 100 to be fully opened. This facilitates the installation and removal of the UAV by personnel and allows for manual operation of the mounting component 4 and the pipe component 5 to close the mounting slot 100 after installation, further improving the stability and reliability of the UAV unmounting device's mounting and unmounting operation.

[0047] Optionally, a limiting post 102 is provided on the side of the mounting slot 100 away from the mounting member 4, and the limiting post 102 is used to limit the angle of rotation of the mounting member 4 in the first direction.

[0048] Specifically, a limiting post 102 is provided on the side of the mounting slot 100 away from the mounting member 4. When the mounting member 4 rotates in the first direction to close the mounting slot 100, the limiting post 102 can block the rotation of the mounting member 4. When the mounting member 4 rotates around the hinge center in the first direction until it abuts against the limiting post 102, the mounting member 4 can no longer rotate, thus avoiding excessive rotation. See also Figure 2In this embodiment, under the loading state, the loading slot 100 is closed, and both the loading component 4 and the pipe component 5 are in a horizontal state. The limiting post 102 is pressed against the upper side of the free end of the loading component 4, and the pipe component 5 is pressed against the lower side of the free end of the loading component 4. The limiting post 102 and the pipe component 5 cooperate to further ensure the stability of the position of the loading component 4, so that the loading slot 100 can maintain a stable closed state under the loading state, thereby improving the accuracy and reliability of the loading operation.

[0049] Optionally, the base 1 includes a lower cover 12 and an upper cover 11. A receiving cavity is formed in the lower cover 12. The servo arm 3, the brake 6, the pipe 5, and the mounting member 4 are all disposed in the receiving cavity. The upper cover 11 is connected to the lower cover 12 to close the receiving cavity. The servo 2 is installed on the side of the lower cover 12 away from the upper cover 11. The output shaft of the servo 2 passes through the lower cover 12, enters the receiving cavity, and is connected to the servo arm 3.

[0050] Specifically, in this embodiment, the base 1 includes a lower cover 12 and an upper cover 11. The lower cover 12 has a receiving cavity, within which a mounting pin is installed. The brake component 6, the pipe component 5, and the mounting component 4 are hinged within the lower cover 12 via the mounting pin. The servo motor 2 is mounted on the side of the lower cover 12 away from the receiving cavity via a first screw 901. The lower cover 12 has a through hole for the output shaft of the servo motor 2 to pass through, allowing the output shaft of the servo motor 2 to extend into the receiving cavity and be fixedly connected to the servo motor rotating arm 3 via a second screw 902. The upper cover 11 is located on one side of the receiving cavity and is connected to the lower cover 12 via a third screw 903. The upper cover 11 seals the receiving cavity, protecting the core working components from exposure, effectively reducing the risk of misoperation, extending the service life of components, and improving the safety and reliability of the device.

[0051] The drone unhooking device provided in this embodiment ensures that the device is completely unhooked before performing attachment operations, such as... Figure 4 As shown, at this time, pipe fitting 5, hanging component 4, and braking component 6 are all in a vertical position. Place the hanging rope into the hanging slot 100, manually rotate the hanging component 4 clockwise, and then rotate the pipe fitting 5 counterclockwise. Figure 5 As shown; until you hear the sound of fitting 5 and brake 6 fastening together, it indicates that fitting 5 has rotated into place, as shown. Figure 2 As shown, the mounting slot 100 is now closed. See Figure 3During the unhooking operation, the servo motor 2 is activated, causing the servo motor arm 3 to rotate counterclockwise by a certain angle. This drives the brake component 6 to rotate clockwise around the hinge center, thereby releasing the position lock on the pipe component 5. Under the influence of gravity, the pipe component 5 rotates clockwise, releasing the restriction on the mounting component 4. Under the influence of gravity, the mounting component 4 rotates counterclockwise, causing the mounting slot 100 to open, thus unhooking the materials. (See also...) Figure 4 After unhooking, servo motor 2 drives servo arm 3 to rotate clockwise back to its initial position, and the elastic force of tension spring 7 pulls brake 6 to rotate counterclockwise back to the vertical position, preparing for the next loading operation. In practical applications, the rotation angle of servo arm 3 can be flexibly set as needed. For example, the rotation angle of servo arm 3 can be set to 45° each time, and the rotation angle and direction can be controlled by servo motor 2.

[0052] The UAV unhooking device provided in this embodiment has a more compact structure and more reasonable stress distribution at the attachment points, allowing it to withstand greater tensile force. The core working components are not exposed when attached, and a clear locking sound is emitted after the pipe 5 is properly installed during attachment operations, reducing the risk of misoperation and improving the device's reliability and durability. The overall structure of the device is simple, reducing manufacturing costs and enabling lightweight design. It also allows for fast and precise attachment and detachment operations while ensuring safety, effectively solving the failure rate problem caused by existing complex structures and adapting to complex field working environments.

[0053] This application also proposes a drone, including a drone body and a drone unhooking device as described above, wherein the drone unhooking device is connected to the drone body.

[0054] Specifically, the drone unhooking device includes a base 1, which is connected to the drone body via a fourth screw, ensuring that the drone unhooking device can be securely installed on the drone body. In practical applications, the drone can carry supplies to a designated location. When it arrives at the delivery area, the operator only needs to control the servo motor 2 to easily open the mounting slot 100 and complete the unhooking and delivery of the supplies.

[0055] Equipped with the aforementioned drone unhooking device, the drone can efficiently complete the task of loading and dropping materials, realizing automation and safety in the process of material transportation and heavy object handling.
