Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a UAV tripod. Background Technology

[0002] In diverse application scenarios such as aerial photography, geographic surveying and agricultural monitoring, drones need to achieve stable take-off and landing and safe parking under different terrain conditions. This places strict requirements on the functionality and adaptability of the tripod. Most traditional drone tripods adopt a fixed structure design, which is connected to the bottom of the drone body by bolts or buckles. Although it can support the drone body to a certain extent, its installation process is cumbersome and requires the use of professional tools to tighten in multiple places. This not only takes a long time, but also increases the complexity of field operations.

[0003] Most existing tripod angles are preset and fixed, lacking a flexible adjustment mechanism. Operators can only barely change the support angle by placing stones or other temporary items under the tripod. This method is not only unstable and inaccurate, but also prone to displacement of the support due to airflow disturbances during takeoff. In scenarios involving high-precision aerial surveys or long-term hovering operations, the inconvenience of tripod angle adjustment seriously affects data acquisition quality and operational efficiency. It also increases equipment wear and battery consumption, failing to meet the dual requirements of precise positioning and rapid deployment for professional UAV operations. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a drone tripod to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drone tripod, comprising a drone body and a support tripod. A linkage mechanism is provided below the drone body. The linkage mechanism includes a support frame and a fixed frame. The support frame is fixed to the bottom surface of the drone body. The fixed frame is rotatably connected to the bottom end of the support frame. A quick-release mechanism is provided between the fixed frame and the support tripod. The quick-release mechanism includes a fixed sleeve and a plug rod. The fixed sleeve is fixed inside the fixed frame. The plug rod is fixed to the top end of the support tripod. A rotating sleeve is rotatably connected to the bottom end of the fixed sleeve. A locking block is fixed to the inner wall of the fixed sleeve. Multiple sets of locking blocks are provided, and each set has a locking hole on its outer wall. A plug plate is fixed to the outer wall of the plug rod. Multiple sets of plug plates are provided and are respectively inserted into multiple sets of locking holes.

[0008] The present invention is further configured such that a transmission frame is rotatably connected to the outer wall of the fixed frame, and a linkage frame is rotatably connected between the top of the transmission frame and the support frame. This design forms a closed-loop transmission chain structure, realizing the effective transmission of torque, enhancing the smoothness and accuracy of angle adjustment, reducing transmission gap, and improving the stability of the overall structure.

[0009] The present invention is further configured such that a micro motor is fixedly provided on the outer wall of the support frame, and the output end of the micro motor is fixedly connected to the linkage frame. The motor drive design realizes the automation and precision of angle adjustment, avoids the instability of manual adjustment, and can realize remote or programmed angle adjustment through the electronic control system, thereby improving the adaptability of the UAV in complex environments.

[0010] The present invention is further configured such that a positioning block is fixedly provided on the inner side of the rotating sleeve, and multiple sets of positioning blocks are provided. A positioning groove is provided on the outer wall of the insertion rod, and multiple sets of positioning grooves are provided and are respectively inserted into multiple sets of positioning blocks. The multi-point positioning structure ensures the accuracy of the installation position of the insertion rod, prevents deviation during rotation, and the multiple sets of design disperse the stress points, thereby improving the connection strength and service life.

[0011] The present invention is further configured such that a push spring is connected to the outer wall of the insertion rod, a stop ring is connected to the top of the push spring, and a pressure ring is fixedly provided on the inner wall of the rotating sleeve. The elastic reset mechanism allows the insertion rod to pop out automatically after unlocking without the need for additional tools to assist in disassembly. The cooperative design of the stop ring and the pressure ring ensures that no lateral displacement occurs when the push spring is compressed, thereby improving the convenience and reliability of operation.

[0012] The present invention is further configured such that all of the multiple sets of insert plates and lock holes are arc-shaped. The arc-shaped design reduces the frictional resistance between the insert plates and lock holes, making the rotation locking process smoother. At the same time, it increases the contact area, improves the connection strength, reduces local stress concentration, and extends the service life of the components.

[0013] The present invention is further configured such that the outer wall of the rotating sleeve is provided with a threaded sleeve, the threaded sleeve is threadedly connected to the outer wall of the rotating sleeve and abuts against the bottom surface of the fixed sleeve. The threaded connection provides precise pressure adjustment capability, forming a second locking guarantee, preventing the rotating sleeve from loosening in a vibration environment, ensuring the reliability and safety of the connection system, and effectively preventing the scaffold from accidentally falling off during high-altitude operations.

[0014] The present invention is further configured such that the inner wall of the threaded sleeve is made of a frosted surface. The frosted surface design increases the friction between the finger and the threaded sleeve, improves the comfort and stability of manual rotation operation, reduces the possibility of slipping in wet environments, and facilitates quick and reliable adjustment operations under various working conditions.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a drone tripod with the following advantages:

[0017] 1. The linkage mechanism achieves precise angle adjustment of the drone's tripod through a combination of support and fixed frames. The support frame is fixed to the bottom of the drone body to provide a stable support point, while the fixed frame is connected to the support frame through a rotating connection to increase the degree of freedom of movement. The transmission frame and linkage frame form a linkage transmission system to effectively transmit power to the fixed frame. The micro motor serves as the power source, providing precise and controllable driving force. The motor drives the linkage frame to drive the entire transmission system to achieve automated adjustment, avoiding the instability of manual adjustment. The entire system forms a closed-loop transmission chain to ensure the smoothness and accuracy of the adjustment process. This design greatly improves the drone's adaptability and stability on irregular terrain and solves the technical problem that traditional fixed-angle tripods cannot cope with complex terrain.

[0018] 2. The quick-release mechanism adopts a plug-in connection method of fixed sleeve and plug rod, realizing the rapid installation and disassembly of the support frame. The fixed sleeve is installed inside the fixed frame to form a stable connection base, and the plug rod is fixed to the top of the support frame as a docking component. The multi-point plug-in design of the locking block and plug plate enhances the connection strength and stability. The rotation locking mechanism of the rotating sleeve can be locked and unlocked by a simple rotation action. The precise alignment of the positioning block and positioning groove ensures the accuracy of the installation position. The elastic reset design of the push spring and the abutment ring facilitates the automatic pop-out of the plug rod during disassembly. The arc-shaped design of the plug plate and locking hole reduces frictional resistance and improves the smoothness of operation. This mechanism can complete the rapid installation and disassembly of the frame without tools, which greatly improves the efficiency of field operations and emergency response capabilities.

[0019] 3. The threaded sleeve design of the quick-release mechanism further enhances the reliability and safety of the entire connection system. The threaded sleeve is installed on the outer wall of the rotating sleeve through a threaded connection to form a second locking guarantee. The threaded connection provides precise pressure adjustment capability to adapt to different working conditions. The threaded sleeve abuts against the bottom of the fixed sleeve to form an effective limit on the rotating sleeve to prevent accidental loosening. The frosted surface design increases friction and improves the comfort and stability of manual operation. This dual locking mechanism ensures the stability of the connection parts of the drone in vibration and impact environments, effectively prevents the tripod from accidentally falling off during high-altitude operations, and significantly improves the safety and reliability of the entire system.

[0029] Please see Figures 1-5 A drone tripod includes a drone body 1 and a support tripod 2. A linkage mechanism is provided below the drone body 1. The linkage mechanism includes a support frame 3 and a fixing frame 4. The support frame 3 is fixed to the bottom surface of the drone body 1. The fixing frame 4 is rotatably connected to the bottom end of the support frame 3. A quick-release mechanism is provided between the fixing frame 4 and the support tripod 2. The quick-release mechanism includes a fixing sleeve 5 and a plug rod 6. The fixing sleeve 5 is fixed inside the fixing frame 4. The plug rod 6 is fixed to the top end of the support tripod 2. A rotating sleeve 7 is rotatably connected to the bottom end of the fixing sleeve 5. A locking block 8 is fixed on the inner wall of the fixing sleeve 5. Multiple sets of locking blocks 8 are provided, and each set has a locking hole 9 on its outer wall. A plug plate 10 is fixed on the outer wall of the plug rod 6. Multiple sets of plug plates 10 are provided and are respectively inserted into multiple sets of locking holes 9.

[0030] A transmission frame 11 is rotatably connected to the outer wall of the fixed frame 4. A linkage frame 12 is rotatably connected between the top of the transmission frame 11 and the support frame 3. This design forms a closed-loop transmission chain structure. When the linkage frame 12 is subjected to force and rotates, the torque is transmitted to the transmission frame 11 through the lever principle. The transmission frame 11 then drives the fixed frame 4 to rotate, realizing the precise adjustment of the angle of the support leg. The rotational connection method of each component ensures the stability and flexibility of the movement process.

[0031] A micro motor 13 is fixedly installed on the outer wall of the support frame 3. The output end of the micro motor 13 is fixedly connected to the linkage frame 12. The motor drive system converts electrical energy into mechanical energy to provide stable and continuous power output to the linkage frame 12, realizing the automated control of the tripod angle adjustment, avoiding the instability of manual adjustment. The direct connection between the motor and the linkage frame 12 reduces transmission loss and improves adjustment accuracy and response speed.

[0032] A positioning block 14 is fixedly provided on the inner side of the rotating sleeve 7. Multiple sets of positioning blocks 14 are provided. A positioning groove 15 is provided on the outer wall of the insertion rod 6. Multiple sets of positioning grooves 15 are provided and are respectively inserted into multiple sets of positioning blocks 14. The positioning blocks 14 and positioning grooves 15 constitute a keyway positioning system to ensure the precise installation position of the insertion rod 6 in the rotating sleeve 7. The multiple sets of designs disperse radial stress, prevent single-point force, and provide a guiding function during rotation to ensure that the insertion plate 10 can be accurately aligned with the lock hole 9.

[0033] A push spring 16 is connected to the outer wall of the insertion rod 6, and a stop ring 17 is connected to the top of the push spring 16. A pressure ring 18 is fixed to the inner wall of the rotating sleeve 7. The elastic reset mechanism works based on Hooke's law. When the insertion rod 6 is inserted, the push spring 16 is compressed and stores elastic potential energy. After unlocking, the potential energy is released and pushes the insertion rod 6 to pop out automatically. The design of the stop ring 17 and the pressure ring 18 ensures that the push spring 16 is subjected to axial force and prevents lateral displacement, thus forming a reliable automatic pop-out mechanism.

[0034] The multiple sets of insert plates 10 and lock holes 9 are all set to be arc-shaped. The arc design is based on geometric principles to reduce the contact friction between the insert plates 10 and lock holes 9, making the rotation insertion process smoother. At the same time, the arc structure increases the contact area, disperses the stress points, avoids stress concentration at sharp angles, and improves the connection strength and component durability.

[0035] The outer wall of the rotating sleeve 7 is provided with a threaded sleeve 19. The threaded sleeve 19 is threadedly connected to the outer wall of the rotating sleeve 7 and abuts against the bottom surface of the fixed sleeve 5. The threaded connection system uses the inclined plane principle of the spiral to convert the rotational motion into axial motion. When the threaded sleeve 19 is tightened, it moves upward and abuts against the bottom surface of the fixed sleeve 5 to form axial pressure, which generates a frictional locking force on the rotating sleeve 7, thus forming a second safety guarantee against loosening.

[0036] The inner wall of the threaded sleeve 19 is made of frosted surface. The frosted surface design is based on the principle of surface roughness, which increases the micro-unevenness of the contact surface, improves the static friction coefficient between the fixed sleeve 5 and the threaded sleeve 19, and reduces the possibility of slippage during operation.

[0037] In this embodiment, when it is necessary to disassemble the support leg 2, loosen the threaded sleeve 19 to release the contact with the fixed sleeve 5. Rotate the rotating sleeve 7 to drive the insertion rod 6 to rotate through multiple sets of positioning blocks 14. The rotation of the multiple sets of insertion rods 6 causes the multiple sets of insertion plates 10 to disengage from the locking hole 9. The elastic reset of the push spring 16 pushes the insertion rod 6 to disengage from the fixed sleeve 5 and the rotating sleeve 7, thus completing the disassembly of the support leg 2. When it is necessary to install the support leg 2, insert the insertion rod 6 into the rotating sleeve 7 and the fixed sleeve. Within 5, multiple sets of positioning blocks 14 are inserted into positioning grooves 15. At the same time, the abutment ring 17 abuts against the bottom surface of the pressure ring 18 and squeezes the push spring 16. At this time, multiple sets of insert plates 10 are parallel to multiple sets of insertion holes. Rotating the rotating sleeve 7 drives the insert rod 6 to rotate. The rotation of the insert rod 6 drives the multiple sets of insert plates 10 to rotate and insert into the lock hole 9. Then, rotating the threaded sleeve 19 causes it to move along the rotating sleeve 7 and press against the outer wall of the fixed sleeve 5 to limit the rotation sleeve 7, thus completing the installation of the support bracket 2.

[0038] More specifically, starting the micro motor 13 drives the linkage frame 12 to rotate along the support frame 3. The linkage frame 12 pulls the transmission frame 11, and the transmission frame 11 pulls the fixed frame 4 to rotate along the support frame 3. At the same time, the fixed frame 4 drives the fixed sleeve 5 and the support leg 2 to move, thereby adjusting the angle of the support leg 2.

[0039] In summary, when the entire equipment is in use or running, but it is necessary to disassemble the support leg 2, loosen the threaded sleeve 19 to release the contact with the fixed sleeve 5, rotate the rotating sleeve 7 to drive the insertion rod 6 to rotate through multiple sets of positioning blocks 14, and the rotation of multiple sets of insertion rod 6 causes multiple sets of insertion plates 10 to disengage from the locking hole 9. Through the elastic reset of the push spring 16, the insertion rod 6 is pushed to disengage from the fixed sleeve 5 and the rotating sleeve 7, thus completing the disassembly of the support leg 2. When it is necessary to install the support leg 2, insert the insertion rod 6 into the rotating sleeve 7. Inside the fixed sleeve 5, multiple sets of positioning blocks 14 are inserted into the positioning grooves 15. At the same time, the abutment ring 17 abuts against the bottom surface of the pressure ring 18 and squeezes the push spring 16. At this time, multiple sets of insert plates 10 are parallel to multiple sets of insertion holes. Rotating the rotating sleeve 7 drives the insert rod 6 to rotate. The rotation of the insert rod 6 drives the multiple sets of insert plates 10 to rotate and insert into the lock hole 9. Then, rotating the threaded sleeve 19 causes it to move along the rotating sleeve 7 and press against the outer wall of the fixed sleeve 5 to limit the rotation sleeve 7, thus completing the installation of the support bracket 2.

[0040] The micro motor 13 is started to drive the linkage frame 12 to rotate along the support frame 3. The linkage frame 12 pulls the transmission frame 11, and the transmission frame 11 pulls the fixed frame 4 to rotate along the support frame 3. At the same time, the fixed frame 4 drives the fixed sleeve 5 and the support leg 2 to move, thereby adjusting the angle of the support leg 2.

[0041] Of all the solutions mentioned above, those involving connections between two components can be selected based on the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other well-known connection methods. These will not be elaborated on here. For all the fixed connections mentioned above, welding is the preferred option.

[0042] In all the solutions mentioned above, those involving the operation of electrical components, unless otherwise specified, are controlled by a controller. Since the devices matched with the controllers are common devices, their control principles and circuit connections are existing, well-known, and mature technologies, and their specific circuit structures will not be described in detail here.

[0043] Of all the solutions mentioned above, those involving motors can be combined with reducers if necessary. The connection structure and working principle between the motor and the reducer are existing known technologies and will not be addressed in this utility model.
