[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments of this utility model, the hanging and dispensing device includes: The mounting bracket 10 can be installed on the aircraft; The mounting and fixing assembly is set on the mounting bracket 10 and includes at least one set of hook units 20 and fixing support units. The hook units 20 are used to connect with the object to be mounted, and the fixing support units are used to apply a tightening force to the object to be mounted. The object to be mounted is fixed by cooperation with the hook units. The deployment execution unit is used to lock and unlock the hook unit 20, enabling the hook unit to connect to the object being mounted when locked and to disconnect from the object when unlocked.
[0026] In some embodiments, such as Figure 5 As shown, the mounting bracket 10 includes a fixed frame 11 and a hanging frame 12; the hanging frame 12 is connected to the fixed frame via two hooks 13, and the connection position of the hooks 13 on the fixed frame is adjustable. By adjusting the connection position of the hooks on the fixed frame, the center of gravity of the suspended deployment device and the suspended device can be adaptively adjusted.
[0027] Specifically, two slide rails 14 are provided on the fixed frame 11, and the hanger 13 is connected to the corresponding slide rail 14 by fixing bolts 15, so as to facilitate flexible adjustment of the position of the hanger on the fixed frame.
[0028] In some embodiments, such as Figure 5 As shown, the mounting bracket 11 is provided with two mounting lugs 16, and each mounting lug 16 is provided with a mounting hole. The mounting bracket is connected to the aircraft by the mounting lugs and bolts to facilitate the installation of the device on the aircraft.
[0029] The mounting bracket 10 has an overall sheet-like frame structure, which reduces the space occupied while ensuring structural strength, making it convenient for mounting on the aircraft.
[0030] In some embodiments, refer to Figure 2 and Figure 3 The hook unit 20 includes a fixed buckle 21 and a rotating buckle 22. The fixed buckle 21 is fixedly connected to the mounting bracket 10, and the rotating buckle 22 is rotatably connected to the mounting bracket 10. Both the fixed buckle 21 and the rotating buckle 22 are provided with matching slots.
[0031] The fixing and rotating buckles of the hook unit can be set up as a whole in a lock box. The lock box is provided with a U-shaped groove, so the entire lock box can be fixedly installed on the mounting bracket during installation.
[0032] The delivery unit is used to drive the rotating buckle to rotate, thereby enabling the hook unit to lock and unlock the object being hung.
[0033] In some embodiments, such as Figure 2 As shown, the deployment execution unit includes a deployment servo motor 31, which is fixedly mounted on the mounting bracket 10. The deployment servo motor 31 is connected to the rotating buckle 22 via a rocker arm 32, and the rotating buckle is driven to rotate by the deployment servo motor.
[0034] In some embodiments, such as Figure 2As shown, the mounting and fixing assembly includes two sets of hook units 20, and the deployment servo motor 31 is connected to the rotation buckle 22 of the two sets of hook units respectively. The two sets of hook units are arranged front and back on the mounting bracket, and the two hook points cooperate with the fixing support unit to achieve stable mounting of the object on the device.
[0035] The two sets of hook units 20 are symmetrically arranged on the front and rear sides of the deployment servo. The deployment servo is connected to a rocker arm 33 and drives the rocker arm 33 to rotate. The two ends of the rocker arm 33 are respectively connected to the rotation latches of the two sets of hook units through rocker arms. At this time, through the layout design of the deployment servo and the two sets of hook units, the locking and unlocking operations on the two hook points can be realized by a single deployment servo.
[0036] In some embodiments, the fixed support unit includes two sets of support members 40; The support member 40 includes a support rod 41 and limiting bolts 42 at both ends of the support rod. The support rod 41 is fixedly installed on the mounting bracket 10. The mounting bracket is set along the axis of the aircraft, and the support rod is set along the transverse direction of the aircraft. The support rod is set perpendicular to the mounting bracket. The limiting bolts are threadedly connected to the support member. The limiting bolts are adjusted to tighten onto the object being mounted.
[0037] The object is supported at four points by four limiting bolts on two sets of support members. At this time, the hook unit provides an upward force to the object, and the two sets of support members provide a counter-tightening force to the object, so as to achieve stable mounting of the object on the device.
[0038] By adjusting the limit bolts and their torque, the tightening force exerted by the limit bolts on the mounted object can be adjusted, thus ensuring a reliable connection between the mounted object and the object.
[0039] In some embodiments, the end of the limiting bolt 42 is provided with a support pad 43 to provide protection for the object being mounted.
[0040] In the mounted state, the object to be mounted is connected to the two hook units respectively. The hook units are locked by the release servo motor, which is in the "zero state". The four limit bolts are adjusted to tighten the object to be mounted, thus fixing the object to the suspending and releasing device. The connection position between the hanger and the fixed frame is adjusted to adjust the center of the device to match the center of gravity of the mounting platform. Then the position of the hanger is locked by the fixing bolts, and the mounting state is entered.
[0041] During the deployment operation, the deployment servo motor is controlled to drive the two rocker arms to rotate and turn the latches, unlocking the two hook units. The object being mounted separates from the device under the action of gravity, thus realizing the deployment operation of the object being mounted.
[0042] In this embodiment, the object to be mounted is attached close to the device, which can reduce the torque of the object in the longitudinal and lateral directions, thereby reducing the impact of the payload deployment on flight.
[0043] In the locked state, the object being hung is suspended on the hook unit, and the object exerts a torque and a downward force on the hook unit. At this time, rotating the hook shaft 23 of the latch 22 limits the hook unit, and the hook unit is in a balanced state. Then, the limiting bolt is tightened against the surface of the object being hung, so that the force and torque received by the object are balanced, achieving a "self-locking" state.
[0044] like Figure 6 As shown, the workflow for hanging and placing operations using the hanging and placing device in this embodiment is as follows: The object to be mounted is hoisted and assembled onto the hook unit. The release servo is controlled to lock the object. If a malfunction occurs, the ground station will issue an alarm and check whether the hook unit is working properly. Adjust the limit bolts to fix the object. When the mounting self-test is successful, adjust the center of gravity of the hanger to the appropriate position. The maintenance crew will conduct a visual inspection. If no problems are found, the maintenance crew will notify the ground station personnel, and the aircraft can take off normally. The delivery mission is carried out according to the planned route. Five minutes before reaching the destination, the ground station personnel initiate the pre-delivery command. After reaching the destination, the ground station personnel send the delivery command to carry out the delivery operation.
[0045] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0046] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0047] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
