Abstract
Description
Technical Field
[0001] This utility model relates to the field of drone catapult technology, specifically to a universal drone catapult device. Background Technology
[0002] There are four main takeoff methods for drones: catapult takeoff, taxiway takeoff, hand-launched takeoff, and rocket-assisted takeoff. In many applications, due to limitations such as takeoff weight and launch site, catapult takeoff offers irreplaceable advantages over the other methods, making it one of the most common launch methods for drones. The specific process of catapult takeoff is as follows: Before launch, the drone is placed on a trolley device on the catapult track. As the drone accelerates with the trolley device to the end of the catapult track, it is quickly released, achieving successful flight.
[0003] Current catapult systems typically have non-adjustable support structures, thus limiting their versatility to support only a single model or specification of UAV. Furthermore, existing catapult systems are relatively complex in structure with numerous connecting components, which affects launch stability and frequently causes UAVs to fall off the catapult during takeoff, resulting in takeoff failure. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a universal drone ejection device to adapt to the ejection requirements of drones of different specifications, while improving the stability, reliability and safety of ejection.
[0005] This utility model solves the above problems through the following technical means:
[0006] A universal UAV ejection device includes a UAV connecting component, a trolley device connected to the UAV connecting component and supporting the UAV, and a power device for pushing the trolley device to slide; the trolley device includes a base frame, a front support member and a rear support member, the front support member includes a front support column, a sleeve and a spring, the bottom end of the front support column is connected to the top end of the sleeve through the spring, and the bottom end of the sleeve is hinged to the base frame.
[0007] Furthermore, the bottom end of the sleeve is hinged to the base frame via a pin.
[0008] Furthermore, the front support and the rear support are respectively located at the front end and the rear end of the base frame.
[0009] Furthermore, the UAV connecting component includes a front connector and a rear connector, the front connector being connected to the front support component, and the rear connector being connected to the rear support component.
[0010] Furthermore, the front connector includes a base and a bent component. The base has left and right limiting grooves. The bent component bends downward and is fixedly connected to the base to form a vertical limiting groove. The top of the front support column is provided with a hook. The hook includes a vertical part and a horizontal part. The vertical part of the hook engages with the left and right limiting grooves, and the horizontal part of the hook engages with the vertical limiting groove.
[0011] Furthermore, the top of the rear support forms a step that restricts the rear connector from moving backward.
[0012] The beneficial effects of this utility model are:

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.
[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", "head", and "tail" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not 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.
[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0023] like Figures 1 to 5 As shown, this utility model discloses a universal UAV ejection device, including a UAV connecting component 1, a trolley device 2 connected to the UAV connecting component and supporting the UAV, and a power device 3 for pushing the trolley device to slide. The trolley device includes a base frame 21, a front support member 22, and a rear support member 23. The front and rear support members are respectively located at the front and rear ends of the base frame and are used to support the front and tail of the UAV, respectively. The front support member includes a front support column 221, a sleeve 222, and a spring 223. The bottom end of the front support column is connected to the top end of the sleeve through the spring. The bottom end of the sleeve is hinged to the base frame. Specifically, the bottom end of the sleeve is hinged to the base frame through a pin 24. In this way, the front support member can swing relative to the base frame, thereby adapting to the support requirements of different UAV models. It should be noted that the hinge freedom can be locked, which is prior art and will not be described in detail here.
[0024] The UAV connecting components include a front connector 11 and a rear connector 12. The front connector is connected to the front support, and the rear connector is connected to the rear support. Specifically, the front connector includes a base 112 and a bent component 111. The base has left and right limiting grooves 113. The bent component bends downward and is fixedly connected to the base to form a vertical limiting groove 114. The top of the front support column is provided with a hook 224, which includes a vertical part 2242 and a horizontal part 2241. The vertical part of the hook engages with the left and right limiting grooves, and the horizontal part of the hook engages with the vertical limiting groove. In this way, the cooperation between the front connector and the hook restricts the UAV's left, right, up, down, and backward degrees of freedom, allowing it to only move forward from the trolley device under the action of inertia. The top of the rear support forms a step that restricts the rear connector from moving backward.
[0025] The power unit is an open-cylinder type power structure, which is suitable for providing power by compressed gas, including but not limited to compressed air, supercritical CO2 phase change and other power sources.
[0026] The work process is as follows:
[0027] Before launch, the drone is placed on the trolley device 2. Under the thrust of the power unit 3, the drone accelerates along the launch track on the power unit 3 with the trolley device 2. When the lift of the drone is sufficient to overcome the spring resistance or accelerate to the end of the track, the drone is quickly released, realizing the successful launch of the drone.
[0028] In summary, the UAV launch device of this application allows the spring 223 to be adjusted according to the weight specifications of the UAV. In addition, since the front support can rotate around the base frame 21 via the pin 24, the launch angle can be adjusted, supporting the launch of different models of UAVs.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
