Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to an electro-hydraulic brake valve controller for UAVs. Background Technology

[0002] An electro-hydraulic brake valve controller for unmanned aerial vehicles (UAVs) is the core control device of the UAV braking system. It integrates electronic control and hydraulic transmission technology. By receiving braking commands from the UAV flight control system (such as the deceleration requirements during takeoff and landing), it precisely adjusts the hydraulic output pressure of the electro-hydraulic brake valve, thereby controlling the braking torque of the braking actuator (such as wheel brake pads).

[0003] The smooth deceleration, precise stopping, and stable gliding direction of the UAV during the ground taxiing phase are achieved by dynamically adapting to the braking requirements under different working conditions (such as load, runway slope, wind speed, etc.), avoiding skidding, rollover, or insufficient braking that would prolong the taxiing distance due to excessive braking. At the same time, it integrates functions such as pressure feedback and fault diagnosis to ensure the safety and reliability of the braking process. It is a key component in the ground motion control of UAVs to ensure safe take-off and landing.

[0004] In existing technologies, wiring connections require tedious manual steps such as stripping, twisting, and wrapping insulation, resulting in extremely low installation efficiency. This significantly increases labor costs, especially during mass production or on-site debugging. Furthermore, manual connections are prone to poor contact, intermittent connections, or short circuits due to improper operation, leading to delays in controller command reception, abnormal brake pressure regulation, and even safety hazards such as brake failure during drone gliding. Therefore, a drone electro-hydraulic brake valve controller is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of an electro-hydraulic brake valve controller for a drone, comprising a docking device 5. A fixed rod 6 is fixedly connected internally to the docking device 5, serving as the fulcrum for the rotation of a rocker arm 7, ensuring stable rocker arm 7 to lock and release the connector 4. The rocker arm 7 is rotatably connected externally to the fixed rod 6, amplifying the operating force through leverage, making it easier to release the restriction on the connector 4 when the switch 10 is pressed. A first spring 8 is fixedly connected internally to the docking device 5, providing a restoring force after the rocker arm 7 rotates, ensuring the rocker arm 7 can quickly return to its original position and relock the connector 4. A push rod 9 is fixedly connected to the other end of the first spring 8, transmitting the elastic force of the first spring 8 to the rocker arm 7, enhancing its restoring effect. A second spring 12 is fixedly connected internally to the docking device 5, providing a buffering force when the connector 4 is inserted, preventing… For components damaged by hard impact, the other end of spring 12 is fixedly connected to connecting rod 13. Connecting rod 13 cooperates with rocker 7 to restrict the position of connector 4, ensuring a stable connection between docking device 5 and connector 3. Connector 4 is movably connected to the other end of connecting rod 13. Connector 4 serves as a signal transmission medium, connecting the starting component and the adjustment component. Connector 3 is fixedly connected to the outside of connector 4. Connector 3 is used to integrate the wiring of power supply 1 and adjustment component, simplifying the wiring structure. Starting component is fixedly connected to the outside of connector 3. Starting component provides power support for the entire controller. Two connecting wires 14 are fixedly connected to the other end of connector 4. Connecting wires 14 transmit control signals to adjustment component to achieve precise adjustment of brake valve. Adjustment component is fixedly connected to the other end of connecting wires 14. Adjustment component drives brake valve through motor 23 to achieve braking control of UAV.

[0033] The starting component includes a connecting wire 2, which connects the power supply 1 to the connector 3 to power the entire controller. One end of the connecting wire 2 is fixedly connected to the outside of the connector 3 to ensure reliable circuit connection. The other end of the connecting wire 2 is fixedly connected to the power supply 1, which provides power to the motor 23 and the speed controller 15.

[0034] The outside of connector 3 contacts the outside of docking device 5. The contact design facilitates quick docking. The outside of connector 4 is slidably connected to the inside of docking device 5. The sliding connection ensures that connector 4 can be smoothly inserted and locked.

[0035] Reference Figure 2 and Figure 4The regulating component includes a speed controller 15, which receives control signals and regulates the speed of the motor 23 to control the braking force. The speed controller 15 is externally fixedly connected to the other end of connecting wire 14 to ensure signal transmission stability. Three connecting wires 16 are fixedly connected to the other end of the speed controller 15, serving as circuit connection media to connect the speed controller 15 to the motor 23. Connecting wires 18 are snap-fitted to the other end of connecting wires 16. This combined structure facilitates quick assembly and disassembly, improving maintenance efficiency. The external fixed connection of 8 is a connecting pipe 19, which is used to protect the internal circuit and fix the buffer rod 20. Multiple buffer rods 20 are fixedly connected inside the connecting pipe 19. The buffer rods 20 provide guidance during docking to ensure that the first docking wire 16 and the second docking wire 18 are accurately docked. The buffer rod 20 is fitted with a spring 3 21. The spring 3 21 absorbs the impact force during docking to avoid damage to the components. The other end of the buffer rod 20 is fixedly connected to a limit plate 22. The limit plate 22 cooperates with the limit groove 17 to prevent the first docking wire 16 from falling off.

[0036] A limiting groove 17 is provided on the outside of the first connecting wire 16. The limiting groove 17 cooperates with the limiting plate 22 to ensure a stable connection between the first connecting wire 16 and the second connecting wire 18. The outside of the limiting plate 22 is slidably connected to the inside of the limiting groove 17. The sliding design makes the docking process smoother.

[0037] The other end of the connecting wire 2 18 is fixedly connected to a motor 23. The motor 23 acts as an actuator to drive the brake valve. One end of the spring 3 21 is fixedly connected to the inside of the connecting pipe 19, and the other end is fixedly connected to the outside of the limiting plate 22. The elastic force of the spring 3 21 ensures that the limiting plate 22 is always tightly attached to the limiting groove 17 to prevent loosening.

[0038] Reference Figure 1 and Figure 2 A switch 10 is slidably connected to the outside of the rocker 7. The switch 10 drives the rocker 7 to rotate by pressing, thereby releasing the connector 4. A limit ring 11 is fixedly connected to the outside of the switch 10. The limit ring 11 prevents the rocker 7 from being damaged due to excessive pressing of the switch 10.

[0039] The external sliding connection of switch 10 is inside the docking device 5. The sliding design makes the operation smoother. The external sliding connection of limit ring 11 is on the inner wall of docking device 5. The sliding range of limit ring 11 ensures that the stroke of switch 10 is controllable.

[0040] Working principle: During the docking stage, the operator inserts the connector head 4 of connector 3 into the docking device 5. The connector head 4 pushes the connecting rod 13 to compress the spring 12, and at the same time triggers the rocker plate 7 to rotate around the fixed rod 6. At this time, the spring 8 applies a pre-tightening force through the push rod 9, so that one end of the rocker plate 7 cooperates with the connecting rod 13, and the connector head 4 is firmly locked from both sides, completing the mechanical interlock between the docking device 5 and the connector 3, ensuring the stability of the electrical connection. When separation is required, press the switch 10 to push the rocker plate 7 to rotate, release the constraint on the connector head 4, and the spring 8 releases its elastic force to assist the rocker plate 7.

[0041] When adjusting the assembly, insert the first connecting wire 16 into the connecting tube 19. The limiting groove 17 on its outside contacts the limiting plate 22 inside the connecting tube 19. During the insertion process, the limiting plate 22 slides along the inclined surface of the limiting groove 17, pushing the buffer rod 20 to compress the third spring 21 and generating elastic potential energy. When the limiting plate 22 slides to the slot of the limiting groove 17, the third spring 21 rebounds and pushes the limiting plate 22 to lock into the slot, forming a firm lock and realizing the quick fixation of the first connecting wire 16 and the second connecting wire 18.

[0042] Power supply 1 supplies power to speed controller 15 through connecting cable 1 2, connector 3, docking device 5 and connecting cable 2 14. Speed ​​controller 15 transmits signals through docking cable to control motor 23 and adjust the brake valve action. The whole process does not require tools and relies on mechanical structure and elastic elements to achieve quick docking, stable locking and convenient separation, which is suitable for reliable operation in the vibration environment of UAV.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
