Description

Technical Field

[0001] This application relates to the field of aircraft airframes, and more particularly to an external rocket booster connection mechanism. Background Technology

[0002] In some situations, drones need to rapidly reach a certain altitude and speed upon takeoff, such as when quickly deploying them for reconnaissance or attack missions; or when there is no suitable runway or launch platform, such as in remote areas or complex terrain, where traditional takeoff methods may be limited. Rocket-assisted launch technology offers high thrust, low cost, mature technology, high reliability, and greater flexibility. It is not dependent on specific launch environments and has high launch efficiency, making it suitable for launching drones under a ton. Therefore, it is widely used, which has spurred the development of drone rocket booster mounts. These mounts reliably connect the drone to the rocket booster, ensuring stability during launch and thus improving launch safety and reliability.

[0003] Currently, the structure of the mounting base for drone rocket boosters is quite complex, making the installation and positioning of rocket boosters time-consuming and labor-intensive. Utility Model Content

[0004] The main objective of this application is to provide an external rocket booster connection mechanism, which addresses the problem of time-consuming and labor-intensive installation and positioning of existing rocket boosters.

[0005] To achieve the above objectives, this application provides an external rocket booster connection mechanism for connecting a rocket booster and a drone. The mechanism includes a first connector and a second connector sequentially connected axially to the rocket booster, and a first mounting base and a second mounting base connected to the drone. The first connector includes two hooks symmetrically connected to the same circumference at the rear end of the rocket booster. Each hook has a bent portion containing an explosive bolt. The bent portions of the two hooks have the same bending direction. The first mounting base has first interfaces adapted to the two bent portions, which pass through their respective interfaces. The second connector includes a first connecting rod, one end of which is vertically connected to the front end of the rocket booster, and the other end of which is vertically connected to a second connecting rod along the axial direction of the rocket booster, with the second connecting rod facing the front end of the rocket booster. The second mounting base has a second interface adapted to the second connecting rod, which passes through the second interface.

[0006] Optionally, the cross-sectional shape of the second interface is circular, and the free end of the second connecting rod is connected to a ball head that is adapted to the second interface, with the ball head located inside the second interface.

[0007] Optionally, the distance between the first connecting rod and the two hooks is equal.

[0008] Optionally, the first mounting base includes a first mounting plate, on which two first ear plates are fixed, and two first interfaces are located on the first ear plates respectively.

[0009] Optionally, a first reinforcing plate is connected between the two first ear plates, and a second reinforcing plate is connected to the outer side of each of the two first ear plates.

[0010] Optionally, the second mounting base includes a second mounting plate, on which a second ear plate is fixed, and the second interface is located on the second ear plate.

[0011] Optionally, a third reinforcing plate is connected to each side of the second ear plate.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] This utility model's external rocket booster connection mechanism, during rocket booster operation, uses a second connecting rod and a second interface to lock the rocket booster in place, preventing directional displacement or accidental detachment. Simultaneously, a hook engages at the first interface, restricting rotation or other directional displacement of the external rocket booster. After the rocket booster completes operation, an explosive bolt inside the controlled bend blasts open the second interface, releasing the connection between the rocket booster's rear end and the first mounting base. Subsequently, the rocket booster swings downwards under gravity; during this swing, the end of the second connecting rod at the front end slides out of the first interface, releasing the front-end connection and achieving safe and rapid detachment of the rocket booster. The structure is simple and easy to install. Attached Figure Description

[0017] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions 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.

[0019] The first embodiment of this utility model provides an external rocket booster connection mechanism for connecting a rocket booster 9 and a drone, such as... Figure 1-3 As shown, the system includes a first connector and a second connector connected axially to a rocket booster 9, and a first mounting base 1 and a second mounting base 2 connected to a drone. The first connector includes two hooks 3 symmetrically connected to the same circumference at the front end of the rocket booster 9. Each hook 3 has a bent portion with an explosive bolt inside. The bent portions of the two hooks 3 have the same bending direction. The first mounting base 1 has first interfaces 4 that are adapted to the two bent portions, and the two bent portions pass through the corresponding first interfaces 4. The second connector includes a first connecting rod 5, one end of which is vertically connected to the rear end of the rocket booster 9, and the other end is vertically connected to a second connecting rod 6 along the axial direction of the rocket booster 9, with the second connecting rod 6 facing the rear end of the rocket booster 9. The second mounting base 2 has a second interface 7 adapted to the second connecting rod 6, and the second connecting rod 6 passes through the second interface 7.

[0020] Furthermore, the distance between the first connecting rod 5 and the two hooks 3 is equal, which can ensure that the hooks 3 are accurately connected to the first interface 4.

[0021] In this embodiment, bolts are used to pass through the fuselage skin and the fuselage frame flange of the UAV in sequence, or the first mounting base 1 and the second mounting base 2 are connected to the fuselage stringer by bolts, and the inner side is fixed with nuts. During installation, the free end of the second connecting rod 6 is first inserted into the second interface 7, and then the rocket booster 9 is rotated to connect the two hooks 3 to the corresponding first interface 4; installation is convenient. When the rocket booster 9 is working, the second connecting rod 6 and the second interface 7 lock the rocket booster 9 in place, preventing directional displacement or accidental detachment. Simultaneously, the hooks 3 are attached to the first interface 4, restricting the rotation of the external rocket booster 9 or preventing displacement in other directions, thus achieving positioning of the rocket booster 9 at both ends with the UAV. After the rocket booster 9 finishes working, the explosive bolt inside the bent section is controlled to blast open the second interface 7, releasing the connection between the rear end of the rocket booster 9 and the first mounting base 1. Then, the rocket booster 9 swings down due to gravity. During the swing, the end of the second connecting rod 6 at the front end of the rocket booster 9 slides out of the first interface 4, releasing the front end connection, and the rocket detaches. This design ensures safe and rapid rocket detachment, meeting the detachment requirements of the external rocket booster 9. The loads at both the front and rear ends of rocket booster 9 are distributed through the skin, fuselage frame, and beams. This design ensures stable and reliable connections, a reasonable force transmission path, and meets the requirements for external installation and use of the externally mounted rocket booster 9.

[0022] For example, the type of explosion bolt can be MD-22.

[0023] It is worth noting that the specific connection positions of the first mounting base 1 and the second mounting base 2 with the UAV can be achieved by installing the first mounting base 1 and the second mounting base 2 on the fuselage frame of the UAV, so that the rocket booster 9 is located on both sides of the UAV fuselage. The fuselage frame is part of the structure of the UAV itself, and its specific structure and the specific installation positions of the first mounting base 1 and the second mounting base 2 are not within the scope of protection of this application. As long as the corresponding connection between the first mounting base 1 and the first connecting member and the second mounting base 2 and the second connecting member can be achieved, it is sufficient. It will not be elaborated here.

[0024] Furthermore, the second interface 7 has a circular cross-sectional shape, and the free end of the second connecting rod 6 is connected to a ball head 8 that is adapted to the second interface 7. The ball head 8 is located inside the second interface 7. Before the rocket booster 9 operates, the free end of the second connecting rod 6 is first inserted into the second interface 7, and then the hook 3 is connected to the first interface 4. At this time, the rocket booster 9 needs to be rotated. The ball head 8 and the circular second interface 7 can prevent damage to the second connecting rod 6 or the second interface 7 when the rocket booster 9 rotates.

[0025] For example, the first mounting base 1 includes a first mounting plate 101, on which two first ear plates 102 are fixed, and two first interfaces 4 are correspondingly located on the first ear plates 102. The first ear plates 102 are parallel to the axis of the rocket booster 9. A first reinforcing plate 103 is connected between the two first ear plates 102, and second reinforcing plates 104 are respectively connected to the outer sides of the two first ear plates 102. The second mounting base 2 includes a second mounting plate 201, on which second ear plates 202 are fixed, and second interfaces 7 are located on the second ear plates 202. The second ear plates 202 are perpendicular to the axis of the rocket booster 9; third reinforcing plates 203 are respectively connected to both sides of the second ear plates 202.

[0026] In this embodiment, the first ear plate 102 is parallel to the axis of the rocket booster 9, and the second ear plate 202 is perpendicular to the axis of the rocket booster 9. That is, the direction of the first interface 4 is perpendicular to the direction of the second interface 7. This allows the second connecting rod 6 to slide out of the first interface 4 under the gravity of the front end of the rocket booster 9 after the hook 3 separates from the first mounting base 1, ensuring that the rocket booster 9 can be safely and quickly detached.

[0027] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
