Description

Technical Field

[0001] This utility model relates to a drone structure with a buffer protection structure, and in particular to a drone structure with a buffer protection structure applied in the field of drone protection. Background Technology

[0002] Traditional protective frames are generally a single, integrated structure, symmetrically installed on the bottom of the drone to cushion the impact during landing. However, this design has certain drawbacks. The protective frame is subject to repeated impacts with the ground, making it prone to wear and tear or damage. Moreover, the ground environment is complex, and the bottom of the protective frame is easily contaminated with mud, sand, and other debris. In such cases, the traditional integrated protective frame can only be disassembled for subsequent repairs and replacements, which is not only difficult to disassemble and reassemble but also wastes materials.

[0003] To address the issues of difficult disassembly and assembly, and material waste during maintenance, a certain drone buffer protection frame on the market adopts a detachable design and has a certain market share.

[0004] Chinese utility model patent CN221738156U discloses a drone buffer protection frame, including a support frame and a base frame installed at the bottom of the drone. The base frame is installed between the bottom ends of the support frame. A buffer component and a disassembly / removal component are provided between the support frame and the base frame. The buffer component includes a fixed connecting rod, a connecting post, a buffer groove, and a buffer spring. The top end of the fixed connecting rod is telescopically connected to the connecting post. This drone buffer protection frame, through its designed buffer component and disassembly / removal component, can transform the traditional one-piece structure of the protection frame into a split structure composed of a support frame and a base frame. When the drone lands, the base frame impacts the ground, and the buffer component buffers and weakens the impact force. If the protection frame needs maintenance and replacement after long-term use, only the base frame needs to be disassembled and reassembled, while the support frame can continue to be used. This design not only improves the efficiency of disassembly and assembly of the protection frame but also increases the utilization rate of the protection frame material and reduces material waste.

[0005] Although the existing protective frame is detachable, its length is fixed. However, the span of the legs of different drone models is different, and some drones have tilted or horizontal legs. The protective frame is difficult to adapt to the installation and use of various drone models. In addition, it requires threads to be drilled on the original drone legs during installation, which requires additional modification procedures during the initial assembly and is not conducive to widespread use. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is how to design a drone structure with a buffer protection structure that is more applicable and easier to install.

[0007] To address the above problems, this utility model provides a drone structure with a buffer protection structure, comprising:

[0008] The base frame is a telescopic and adjustable long pole.

[0009] Wear-resistant strips are fixed to the lower end of the base frame;

[0010] The buffer support is installed on the upper surface of the base frame and serves as a buffer and protection function.

[0011] An adjustable mounting platform is installed on the upper end of the buffer support. The adjustable mounting platform can adjust the angle and direction of its upper end.

[0012] The leg connector is mounted on the upper end of the adjustable mounting platform, and the leg connector is movably connected to the upper end of the buffer support body through the adjustable mounting platform.

[0013] The foot connector includes a stud, a sleeve, and a second bolt. The upper end of the stud is fitted onto the end of the UAV foot. The thread of the second bolt passes through the upper end of the stud, and the axis of the second bolt coincides with the radial direction of the stud. One end of the second bolt abuts against the periphery of the UAV foot. The sleeve is threaded onto the lower part of the stud, and the lower end of the sleeve is rotatably connected to the upper end of the adjustable mounting platform.

[0014] In the aforementioned drone structure with a buffer protection feature, the base frame is modified to be telescopic, allowing it to adapt to drones with varying leg strides. The adjustable mounting platform design allows for adjustment of the angle and orientation of the leg connectors, accommodating drone legs in different postures. Furthermore, the existing connection structure is improved through the design of the leg connectors, enabling a stable connection without requiring threaded grooves on the original drone legs. This avoids the need for additional modification steps during initial assembly. Overall, this significantly enhances the applicability and ease of use of the drone structure with a buffer protection feature, facilitating its widespread adoption.

[0015] As a further improvement of this application, a threaded groove is provided on the outer side of the lower part of the stud, a slot is provided on the upper part of the stud, and a threaded hole is provided on the periphery of the slot to penetrate the stud. The second bolt is threaded to fit the thread of the threaded hole, and the slot is used to accommodate the UAV feet.

[0016] The upper part of the sleeve is integrally formed with a threaded section that matches the threaded groove.

[0017] As a further improvement to this application, the adjustable mounting platform includes:

[0018] The fixing block is fixed to the upper end of the buffer support;

[0019] The bracket is installed on the upper part of the fixed block;

[0020] A rotating rod is rotatably connected to a bracket, and the axis of the rotating rod extends horizontally.

[0021] The support rod and the rotating rod are integrally formed around the support rod, and the end of the support rod away from the rotating rod is fitted with a bearing.

[0022] The lower part of the sleeve is rotatably mounted on the support rod via a bearing.

[0023] As a further improvement of this application, the adjustable mounting platform also includes a rotating disk, which is rotatably connected to the upper part of the fixed block, and the lower end of the bracket is fixed to the upper end of the rotating disk.

[0024] As another improvement of this application, the base frame includes a sleeve rod and a connecting rod. There are two sleeve rods arranged symmetrically. Each sleeve rod has a sliding groove, and the openings of the two sliding grooves are arranged opposite to each other.

[0025] The two ends of the connecting rod are slidably inserted into two grooves respectively, and the top of the sleeve rod is screwed with a first bolt. The lower end of the first bolt passes through the top of the sleeve rod and abuts against the top of the connecting rod.

[0026] As another improvement to this application, the cushioning support includes:

[0027] A fixed sleeve is fixed at its lower end to the upper surface of the sleeve rod, and a movable cavity is provided inside the fixed sleeve.

[0028] The piston rod has its lower end movably inserted into the fixed sleeve. The lower end of the piston rod is integrally formed with a piston plate whose diameter is the same as the inner diameter of the movable cavity. A vertically penetrating damping hole is opened on the piston plate.

[0029] The lower end of the spring is fixed to the bottom wall of the movable cavity, and the upper end of the spring is fixed to the bottom surface of the piston plate.

[0030] The upper end of the piston rod is fixed to the bottom of the fixed block.

[0031] In summary, by changing the base frame to a telescopic structure, it can be adapted to use with drones of different strides; and through the design of the adjustable mounting platform, the angle and orientation of the strut connectors can be adjusted, thus adapting to use with drone struts in different postures.

[0032] Furthermore, when connecting the drone structure with the buffer protection structure to the drone feet, the operator only needs to place the upper end of the stud onto the end of the drone foot, then tighten the second bolt so that one end of the second bolt abuts against the periphery of the drone foot, thus fixing the stud to the drone foot. Afterward, simply rotate the sleeve to connect the sleeve to the stud. By improving the existing connection structure, the improved foot connector can achieve a stable connection without needing to create threaded grooves on the original drone foot, thus avoiding the need for additional modification procedures during initial assembly. This comprehensively enhances the applicability and ease of use of the drone structure with the buffer protection structure, thereby facilitating its widespread adoption. Attached Figure Description

[0040] The following describes one embodiment of this application in detail with reference to the accompanying drawings.

[0041] Implementation method 1:

[0042] Figure 1-5 The diagram shows a drone structure with a buffer protection structure, including: a base frame 1, a wear-resistant strip 2, a buffer support body 3, an adjustable mounting platform 4, and a leg connector 5;

[0043] The base frame 1 is a telescopic and adjustable long rod. The wear-resistant strip 2 is fixed to the lower end of the base frame 1, and the buffer support 3 is installed on the upper surface of the base frame 1 and plays a buffering and protective role.

[0044] The adjustable mounting platform 4 is installed on the upper end of the buffer support 3. The adjustable mounting platform 4 can adjust the angle and direction of its upper end.

[0045] The support leg connector 5 is installed on the upper end of the adjustable mounting platform 4, and the support leg connector 5 is movably connected to the upper end of the buffer support 3 through the adjustable mounting platform 4.

[0046] The foot connector 5 includes a stud 51, a sleeve 52, and a second bolt 53. The upper end of the stud 51 is fitted onto the end of the UAV foot. The second bolt 53 is threaded through the upper end of the stud 51. The axis of the second bolt 53 is radially aligned with the stud 51. One end of the second bolt 53 abuts against the periphery of the UAV foot. The sleeve 52 is threaded onto the lower part of the stud 51, and the lower end of the sleeve 52 is rotatably connected to the upper end of the adjustable mounting platform 4.

[0047] Based on the above structure, by changing the base frame 1 to a telescopic structure, it can be adapted to use with drones with different strides; and by designing the adjustable mounting platform 4, the angle and orientation of the foot connector 5 can be adjusted, thus adapting to use with drone feet in different postures (such as tilted, horizontal, vertical, etc.).

[0048] Furthermore, when connecting the drone structure with the buffer protection structure to the drone feet, the operator only needs to place the upper end of the stud 51 onto the end of the drone feet, and then tighten the second bolt 53 so that one end of the second bolt 53 abuts against the periphery of the drone feet, thus fixing the stud 51 to the drone feet. After that, simply rotate the sleeve 52 to connect the sleeve 52 to the stud 51. By improving the existing connection structure, the improved foot connector 5 can achieve a stable connection without opening threaded grooves on the original drone feet, thus avoiding the need for additional modification procedures during initial assembly. This comprehensively improves the applicability and ease of use of the drone structure with the buffer protection structure, thereby facilitating its widespread adoption.

[0049] Furthermore, a threaded groove 511 is provided on the lower outer side of the stud 51, a slot 512 is provided on the upper part of the stud 51, and a threaded hole 513 is provided on the periphery of the slot 512 to penetrate the stud 51. The second bolt 53 is threadedly matched with the threaded hole 513, and the slot 512 is used to accommodate the drone feet.

[0050] The upper part of the sleeve 52 is integrally formed with a threaded part 521 that is adapted to the threaded groove 511.

[0051] Furthermore, the adjustable mounting platform 4 includes: a fixed block 41, a rotating disk 42, a bracket 43, a rotating rod 44, and a support rod 45. The fixed block 41 is fixed to the upper end of the buffer support body 3.

[0052] The bracket 43 is installed on the upper part of the fixed block 41, and the rotating rod 44 is rotatably connected to the bracket 43, with the axis of the rotating rod 44 extending horizontally.

[0053] A support rod 45 is integrally formed on the periphery of the rotating rod 44, and a bearing 46 is snapped into the end of the support rod 45 away from the rotating rod 44.

[0054] The lower part of the sleeve 52 is rotatably sleeved on the support rod 45 via the bearing 46;

[0055] The rotating disk 42 is rotatably connected to the upper part of the fixed block 41, and the lower end of the bracket 43 is fixed to the upper end of the rotating disk 42.

[0056] When the rotating disk 42 rotates, it can drive the bracket 43, the rotating rod 44 and the support rod 45 to rotate synchronously, thereby adjusting the horizontal orientation of the support rod 45. When the rotating rod 44 rotates, it can adjust the vertical angle of the support rod 45, thereby realizing multi-directional flexible adjustment of the support rod 45. That is, it can adjust the orientation and angle of the sleeve 52 to adapt to the use of drone feet in different postures, thereby improving the applicability of the drone structure with buffer protection structure.

[0057] Furthermore, the base frame 1 includes a sleeve rod 11 and a connecting rod 12. There are two sleeve rods 11 arranged symmetrically. Each sleeve rod 11 has a sliding groove 111, and the openings of the two sliding grooves 111 are arranged opposite to each other.

[0058] The two ends of the connecting rod 12 are slidably inserted into the two sliding grooves 111 respectively. The top of the sleeve rod 11 is screwed with a first bolt 13, the lower end of the first bolt 13 passes through the top of the sleeve rod 11 and abuts against the top of the connecting rod 12.

[0059] Users can adjust the distance between the two sleeve rods 11 by pulling them, thereby adjusting the overall length of the base frame 1 to accommodate drone legs of different spans. After adjustment, simply tighten the first bolt 13 to fix the two sleeve rods 11 to the connecting rod 12, ensuring the structural stability of the base frame 1 during use.

[0060] Furthermore, the buffer support 3 includes: a fixed sleeve 31, a piston rod 32 and a spring 33. The lower end of the fixed sleeve 31 is fixed to the upper surface of the sleeve rod 11, and a movable cavity 311 is provided inside the fixed sleeve 31.

[0061] The lower end of the piston rod 32 is movably inserted into the fixed sleeve 31. The lower end of the piston rod 32 is integrally formed with a piston plate 321 with a diameter consistent with the inner diameter of the movable cavity 311. A vertically penetrating damping hole 3211 is opened on the piston plate 321.

[0062] The lower end of the spring 33 is fixed to the bottom wall of the movable cavity 311, and the upper end of the spring 33 is fixed to the bottom surface of the piston plate 321.

[0063] The upper end of piston rod 32 is fixed to the bottom of fixing block 41;

[0064] By setting the damping hole 3211, when the piston rod 32 drives the piston plate 321 to press down, the air passing through the damping hole 3211 can generate a damping effect, thereby making the buffer support 3 have a damping buffering effect, weakening or even eliminating the repeated vibration caused by using only the spring 33 for shock absorption, and providing better protection for the drone.

[0065] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
