Technical Field

[0001] This application relates to the field of airdrop equipment technology, and more specifically, to a dual-mounted airdrop device with charging and discharging functions. Background Technology

[0002] An airdropper is a device that can drop supplies, equipment, or personnel from the air to a designated location. It is used to airdrop weapons, ammunition, food, and other supplies, and can also quickly drop relief supplies such as medicines, food, and life-saving equipment to provide timely assistance to disaster-stricken areas or personnel. It is widely used in military, rescue, scientific research and other fields.

[0003] A dual-mount airdropper is a device that can carry two items at the same time and drop them as needed. It is commonly used in the field of drone airdrops and is suitable for rescue missions, material delivery and other scenarios, providing efficient and accurate aerial delivery capabilities.

[0004] Through long-term observation, it has been found that some airdrop devices use non-adjustable metal buckles, which can only be adapted to airdrop boxes of specific sizes. Some airdrop devices use Velcro straps, but the strap length adjustment range is limited, and the fixing strength decreases after adjustment. During the airdrop descent and landing impact, the airdropped items may shift, fall off, or even be damaged.

[0005] In view of this, we propose a dual-mounted airdrop device with charging and discharging functions. Summary of the Invention

One end of the fixing strap is used to fix the airdropped item, and the other end can be adjusted in circumference via a Velcro fastener. The output shaft of the servo motor is connected to the connector, and the connector has three angle adjustment holes. The fixed shaft passes through the angle adjustment hole of the connector. Adjust the hole position and adapt it to the fixing buckle of the fixing strap; the indicator light group is electrically connected to the charging and discharging module and the airdrop controller to display the working status of the charging and discharging module; the interface includes a power interface, a control signal interface and at least two discharge interfaces, the power interface, control signal interface and discharge interface are all electrically connected to the airdrop controller, the charging and discharging module is electrically connected to the airdrop controller, the airdrop controller can control the charging and discharging module to perform charging or discharging actions according to the signal received by the control signal interface, and control the servo drive connector to drive the fixed shaft to move, so as to realize the fixing or release of the fixing strap.

[0008] As an optional solution to the technical solution of this application, a bracket is also provided inside the receiving cavity. The bracket is fixedly connected to the lower shell, and the two charging and discharging modules are respectively fixed on the bracket.

[0009] As an optional solution to the technical solution of this application, both indicator light groups are electrically connected to the charging and discharging module, and are used to display the control signal test, charging in progress, charging complete, discharging in progress, and discharging complete status of the two charging and discharging modules, respectively.

[0010] As an optional solution to the technical solution of this application, the upper shell and the lower shell are provided with strap fixing holes that are adapted to the fixing straps.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3 This application discloses a dual-mounted airdrop device with charging and discharging functions, including an upper shell 1, a lower shell 2, an airdrop controller 3, two charging and discharging modules 4, a servo motor 5, a connector 6, a fixing shaft 7, two fixing straps 8, two indicator light groups 9, and an interface for power supply and signal transmission. The upper shell 1 and lower shell 2 cooperate to form a receiving cavity, and the airdrop controller 3, charging and discharging modules 4, and servo motor 5 are all disposed in the receiving cavity. One end of the fixing strap 8 is used to fix the airdropped item, and the other end can be adjusted in circumference by a Velcro fastener. The output shaft of the servo motor 5 is connected to the connector 6, and the connector 6 has three angle adjustment holes. The fixing shaft 7 passes through the connector. The angle adjustment hole of 6 is adapted to the fixing buckle of the fixing strap 8; the indicator light group 9 is electrically connected to the charging and discharging module 4 and the airdrop controller 3, and is used to display the working status of the charging and discharging module 4; the interface includes a power interface, a control signal interface and at least two discharge interfaces, the power interface, control signal interface and discharge interface are all electrically connected to the airdrop controller 3, the charging and discharging module 4 is electrically connected to the airdrop controller 3, and the airdrop controller 3 can control the charging and discharging module 4 to perform charging or discharging actions according to the signal received by the control signal interface, and control the servo motor 5 to drive the connecting piece 6 to move the fixing shaft 7, so as to realize the fixing or releasing of the fixing strap 8;

[0021] The upper shell 1 and lower shell 2 form a receiving cavity, in which the airdrop controller 3, two charging / discharging modules 4, and servo motor 5 are all housed, achieving integrated protection of the components. Power is then supplied to the power interface, the control signal interface receives commands and transmits them to the airdrop controller 3, and the discharge interface is used for power output. All three are electrically connected to the airdrop controller 3. After receiving the signal, the airdrop controller 3 controls the charging / discharging modules 4 to perform charging or discharging actions. When it is necessary to secure the airdropped item, one end of the securing strap 8 secures the item, and the other end is adjusted for circumference via a hook and loop fastener. The output shaft of the servo motor 5 is connected to the connector 6, and the fixing shaft 7 passes through the connector 6. The angle adjustment hole is adapted to the fixing buckle 8. The airdrop controller 3 controls the servo motor 5 to drive the connector 6 to move the fixed shaft 7, so as to fix or release the fixing strap 8. The indicator light group 9 is electrically connected to the charging and discharging module 4 and the airdrop controller 3 to display the charging and discharging status. With the integration of dual mounting and charging and discharging functions, the airdrop load is simplified and the practicality is improved. At the same time, the circumference of the fixing strap 8 can be adjusted to adapt to different sizes of airdropped items, expanding the scope of application. The angle adjustment hole ensures the precise movement of the fixed shaft 7. The indicator light group 9 facilitates real-time monitoring, improving reliability and maintenance efficiency.

[0022] Reference Figures 1-3 The cavity is also equipped with a support 10, which is fixedly connected to the lower shell 2. The two charging and discharging modules 4 are respectively fixed on the support 10. The support 10 in the cavity is fixed to the lower shell 2, and the two charging and discharging modules 4 are respectively fixed on the support 10, which provides a stable mounting carrier for the charging and discharging modules 4, avoids displacement of the modules due to air-drop vibration, enhances the installation stability of the charging and discharging modules 4, prevents vibration damage, and ensures stable operation of the charging and discharging function.

[0023] Reference Figures 1-3 Both indicator light groups 9 are electrically connected to the charging / discharging module 4, and are used to display the control signal test, charging, charging complete, discharging, and discharging complete states of the two charging / discharging modules 4, respectively. The two indicator light groups 9 are electrically connected to the corresponding charging / discharging module 4. If the signal transmission is normal, the indicator light group 9 will light up a specific test indicator (such as solid blue); if the signal transmission is abnormal, the indicator light group 9 will not respond or will light up a fault indicator (such as flashing red). The operator can quickly judge the signal connection status of the charging / discharging module 4 by observing the indicator light status. By using two indicator light groups 9 connected to the two charging / discharging modules 4 respectively, the five states of "control signal test, charging, charging complete, discharging, and discharging complete" of a single charging / discharging module can be displayed independently, avoiding the problem of confusion caused by a single indicator light group.

[0024] Reference Figures 1-3 The upper shell 1 and the lower shell 2 are provided with strap fixing holes 11 that are adapted to the fixing strap 8; the strap fixing holes 11 of the upper shell 1 and the lower shell 2 allow the middle part of the fixing strap 8 to pass through, and the stability of the fixing strap 8 is enhanced by the action of the strap fixing holes 11.

[0025] Reference Figures 1-3 The angle adjustment holes of the connector 6 are spaced apart along its length. If there is a deviation between the servo motor 5 and the swing arm during assembly or use, the fixed shaft 7 can be installed at different hole positions to compensate for the deviation and avoid the travel deviation of the fixed shaft 7. This step can ensure the movement accuracy of the fixed shaft 7 and ensure that the fixing strap 8 is reliably fixed and released.

[0026] In summary, the dual-mounted airdrop device with charging and discharging functions disclosed in this application, when in use, forms a cavity with the upper shell 1 and lower shell 2. The airdrop controller 3, two charging and discharging modules 4, and servo motor 5 are all placed inside the cavity, achieving integrated protection of the components. Subsequently, power is supplied to the power interface, the control signal interface receives commands and transmits them to the airdrop controller 3, and the discharge interface is used for power output. All three are electrically connected to the airdrop controller 3. After receiving the signal, the airdrop controller 3 controls the charging and discharging modules 4 to perform charging or discharging actions. When it is necessary to fix the airdropped item, one end of the fixing strap 8 fixes the airdropped item, and the other end is adjusted for circumference via a hook and loop fastener. The output shaft of the servo motor 5 is connected to the connector 6, and the fixing shaft 7 passes through the angle adjustment hole of the connector 6 and is adapted to the fixing buckle of the fixing strap 8. The airdrop controller 3 controls the servo motor 5 to drive the connector 6 to move the fixing shaft 7, thereby fixing or releasing the fixing strap 8. The indicator light group 9 is connected to the charging and discharging modules 4 and the airdrop... The controller 3 is electrically connected and displays the charging and discharging status. The bracket 10 inside the cavity is fixed to the lower shell 2. The two charging and discharging modules 4 are respectively fixed on the bracket 10, providing a stable mounting carrier for the charging and discharging modules 4 and preventing the modules from shifting due to air-drop vibration. The two indicator light groups 9 are electrically connected to the corresponding charging and discharging modules 4. If the signal transmission is normal, the indicator light group 9 will light up a specific test indicator light (such as a solid blue light); if the signal transmission is abnormal, the indicator light group 9 will not respond or will light up a fault indicator light (such as a flashing red light). The operator can quickly judge the signal connection status of the charging and discharging module 4 through the indicator light status. The strap fixing holes 11 on the upper shell 1 and the lower shell 2 allow the middle of the fixing strap 8 to pass through. The angle adjustment holes of the connector 6 are set at intervals along the length. During assembly or use, if there is a deviation between the servo motor 5 and the swing arm, different hole positions can be selected to install the fixing shaft 7 to compensate for the deviation and prevent the fixed shaft 7 from offsetting its stroke.
